FORWARD-LOOKING STATEMENTS

          This report contains forward-looking statements that are based on management's beliefs, assumptions, current expectations, estimates and projections about the financial services industry, the economy, and Southern Michigan Bancorp, Inc. Such statements are based upon current beliefs and expectations and involve substantial risks and uncertainties which could cause actual results to differ materially from those expressed or implied by such forward-looking statements. These statements include, among others, statements related to real estate valuation, future levels of non-performing loans, the rate of asset dispositions, dividends, future growth and funding sources, future liquidity levels, future profitability levels, the effects on earnings of changes in interest rates and the future level of other revenue sources. Management's determination of the provision and allowance for loan losses, the appropriate carrying value of intangible assets (including goodwill, mortgage servicing rights and deferred tax assets) and the fair value of investment securities (including whether any impairment on any investment security is temporary or other-than-temporary and the amount of any impairment) involves judgments that are inherently forward-looking. All of the information concerning interest rate sensitivity is forward-looking. Management's assumptions regarding pension and other post retirement plans involve judgments that are inherently forward-looking. Our ability to successfully implement new programs and initiatives, increase efficiencies, respond to declines in collateral values and credit quality, maintain our current level of deposits and other sources of funding, and improve profitability is not entirely within our control and is not assured. The future effect of changes in the real estate, financial and credit markets and the national and regional economy on the banking industry, generally, and Southern Michigan Bancorp, Inc., specifically, are also inherently uncertain. These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions ("risk factors") that are difficult to predict with regard to timing, extent, likelihood and degree of occurrence. Therefore, actual results and outcomes may materially differ from what may be expressed or forecasted in such forward-looking statements. Southern Michigan Bancorp, Inc. does not undertake to update forward-looking statements to reflect the impact of circumstances or events that may arise after the date of the forward-looking statements.

          Risk factors include, but are not limited to, the risk factors described in "Item 1A - Risk Factors" of this report; the timing and level of asset growth; changes in market interest rates; changes in banking laws and regulations; changes in tax laws; changes in prices, levies and assessments; the impact of technological advances and issues; governmental and regulatory policy changes; opportunities for acquisitions and the effective completion of acquisitions and integration of acquired entities; the possibility that anticipated cost savings and revenue enhancements from acquisitions, restructurings, reorganizations and bank consolidations may not be realized at amounts projected, at all or within expected time frames; the local and global effects of the ongoing war on terrorism and other military actions; changes in value and credit quality of investment securities; and current uncertainties and fluctuations in the financial markets and stocks of financial services providers due to concerns about credit availability and concerns about the Michigan economy in particular. These and other factors are representative of the risk factors that may emerge and could cause a difference between an ultimate actual outcome and a preceding forward-looking statement. We undertake no obligation to update or revise our forward-looking statements to reflect developments that occur or information obtained after the date of this report.

PART I

General

          Southern Michigan Bancorp, Inc. ("Southern" the "Company" "we" "our" or "us") is a bank holding company registered under the Bank Holding Company Act of 1956, as amended. Southern was incorporated on March 1, 1982, as a Michigan corporation. Southern was formed to create a bank holding company for the purpose of acquiring all of the capital stock of Southern Michigan Bank & Trust, a Michigan state-chartered bank ("Southern Michigan Bank" or "the Bank") (formerly Southern Michigan National Bank), which it did in November 1982. Southern is also the parent company of Southern Michigan Bancorp Capital Trust I, a Delaware statutory trust. On December 1, 2007, Southern acquired FNB Financial, (formerly, The First National Bank of Three Rivers), a Michigan state-chartered bank. On April 20, 2009 FNB Financial was consolidated with and into Southern Michigan Bank. At December 31, 2009, Southern, on a consolidated basis, had shareholders' equity of $45.7 million.

          Southern Michigan Bank is the parent company of SMB&T Financial Services, Inc., a Michigan corporation, and FNB Financial Services, Inc., a Michigan corporation.

          Through the Bank, we operate 18 banking offices located in Athens, Battle Creek, Camden, Cassopolis, Centreville, Coldwater, Constantine, Hillsdale, Marshall, Mendon, North Adams, Tekonsha, Three Rivers, and Union City, Michigan. At December 31, 2009, on a consolidated basis, we had assets of $462.4 million, deposits of $380.9 million, a net loan portfolio of $327.0 million, and had trust assets under management totaling $208.2 million.

          Our business, which we conduct primarily through the Bank, is concentrated in a single industry segment - commercial banking. We offer a variety of deposit, payment, credit and other financial services to all types of customers. These services include time, savings, and demand deposits, safe deposit services, and automated teller machine services. Loans, including both commercial and consumer, are extended primarily on a secured basis to corporations, partnerships and individuals. Commercial lending covers such categories as business, industry, agricultural, construction, inventory and real estate. Consumer lending covers direct and indirect loans to purchasers of residential real property and consumer goods. We offer trust and investment services, which include investment management, trustee services, IRA rollovers and retirement plans, institutional and personal custody, estate settlement, wealth management, estate planning assistance, wealth transfer planning assistance, charitable gift planning assistance, and cash management custody. No material part of our business is dependent upon a single customer or very few customers, the loss of which would have a material adverse effect on us.

          Effective November 20, 2009, the operations of SMB Mortgage Company were consolidated with and into the Bank, and SMB Mortgage Company was subsequently dissolved and liquidated. All products and services previously provided by SMB Mortgage Company are now provided by the Bank.

Competition

          Our business is highly competitive. We face significant competition from commercial banks, saving and loan associations, credit unions, commercial and consumer finance companies, insurance companies and leasing companies. We also face competition from money market mutual funds, investment and brokerage firms and nonfinancial institutions, which provide many of the financial services we offer. Many of our non-bank competitors are not subject to the same extensive federal regulations that govern bank holding companies and banks. Such non-bank competitors may, as a result, have certain advantages over us in providing some services. The principal methods of competition that we face are price (interest rates paid on deposits, interest rates charged on borrowings and fees charged for services) and service (convenience and quality of services rendered to customers).

Supervision and Regulation

          We are extensively regulated and are subject to a comprehensive regulatory framework that imposes restrictions on our activities, minimum capital requirements, lending and deposit restrictions, dividend restrictions, and numerous other requirements. This system of regulation is primarily intended for the protection of depositors, federal deposit insurance funds and the banking system as a whole, rather than for the protection of shareholders and creditors of Southern. Many of these laws and regulations have undergone significant change in recent years and are likely to change in the future. Future legislative or regulatory change, or changes in enforcement practices or court rulings, may have a significant and potentially adverse impact on our operations and financial condition. Our non-bank subsidiaries are also subject to various federal and state laws and regulations.

          Recent Regulatory Developments

          Emergency Economic Stabilization Act of 2008: On October 3, 2008, the Emergency Economic Stabilization Act of 2008 (EESA) was enacted. EESA enables the federal government, under terms and conditions to be developed by the Secretary of the Treasury, to insure troubled assets, including mortgage-backed securities, and collect premiums from participating financial institutions. EESA includes, among other provisions: (a) the $700 billion Troubled Assets Relief Program (TARP), under which the Secretary of the Treasury is authorized to purchase, insure, hold, and sell a wide variety of financial instruments, and (b) an increase in the amount of deposit insurance provided by the Federal Deposit Insurance Corporation ("FDIC"). Under the TARP, the Department of

Treasury authorized a voluntary capital purchase program ("CPP") to purchase senior preferred shares of qualifying financial institutions that elected to participate by November 14, 2008. We did not participate in the CPP.

          EESA temporarily raised the limit on federal deposit insurance coverage from $100,000 to $250,000 per depositor. The limit is scheduled to return to $100,000 on January 1, 2014. Separate from EESA, in October 2008, the FDIC also announced the Temporary Liquidity Guarantee Program. Under one component of this program, the FDIC is temporarily providing unlimited coverage for noninterest bearing transaction deposit accounts through June 30, 2010.

          Financial Stability Plan: On February 10, 2009, the Financial Stability Plan ("FSP") was announced by the U.S. Treasury Department. The FSP is a comprehensive set of measures intended to shore up the financial system. The core elements of the plan include making bank capital injections, creating a public-private investment fund to buy troubled assets, establishing guidelines for loan modification programs and expanding the Federal Reserve lending program.

          American Recovery and Reinvestment Act of 2009: On February 17, 2009, the American Recovery and Reinvestment Act of 2009 ("ARRA") was enacted. ARRA is intended to provide a stimulus to the U.S. economy in the wake of the economic downturn brought about by the subprime mortgage crisis and the resulting credit crunch. The bill includes federal tax cuts, expansion of unemployment benefits and other social welfare provisions, and domestic spending in education, healthcare, and infrastructure, including the energy structure. The new law also includes numerous non-economic recovery related items, including a limitation on executive compensation in federally aided banks. Under ARRA, an institution will be subject to a number of restrictions and standards throughout the period in which any obligation arising from financial assistance provided under TARP remains outstanding.

          Homeowner Affordability and Stability Plan: On February 18, 2009, the Homeowner Affordability and Stability Plan ("HASP") was announced by the President of the United States. HASP is intended to support a recovery in the housing market and ensure that workers can continue to pay off their mortgages through the following elements:

          More details regarding HASP are expected to be announced at a future date.

          Deposit Insurance Premiums: On November 12, 2009, the FDIC adopted a final rule on assessment regulations to require depository institutions to prepay their quarterly risk-based assessments for the fourth quarter of 2009, and for all of 2010, 2011 and 2012, on December 30, 2009. The projected assessment base for each quarter represents the September 30, 2009 assessment base increased quarterly by a 5 percent annual growth rate. This rule resulted in a prepaid assessment totaling $2.2 million for the Bank.

          Temporary Liquidity Guarantee Program: In November 2008, the FDIC adopted a final rule relating to the Temporary Liquidity Guarantee Program ("TLGP"). The TLGP, an initiative to counter the system-wide crisis in the nation's financial sector, was amended by the FDIC in August 2009 to extend maturity dates originally adopted under the November 2008 final rule. Under the TLGP, the FDIC will (i) guarantee, through the earlier of maturity or December 31, 2012, certain newly-issued senior unsecured debt issued by participating institutions on or after October 14, 2008 and through October 31, 2009 and (ii) provide full FDIC deposit insurance coverage for covered accounts, which are defined as noninterest-bearing transaction deposit accounts, Negotiable Order of Withdrawal ("NOW") accounts paying less than 0.5% interest per annum and Interest on Lawyers Trust Accounts ("IOLTA") held at participating FDIC-insured institutions through June 30, 2010. The fee assessment for coverage of senior unsecured debt ranges from 50 basis points to 100 basis points per annum, depending on the initial maturity of the debt. The fee assessment for deposit insurance coverage is an annualized 10 basis points assessed quarterly on amounts in covered accounts exceeding $250,000. Southern has elected to participate in both guarantee programs.

In October 2009, the FDIC also established a limited, six-month emergency guarantee facility upon expiration of the debt guarantee program, under which certain eligible participating entities can issue FDIC-guaranteed debt starting October 31, 2009 through April 30, 2010. The fee for issuing debt under the emergency facility will be at least 300 basis points per annum. At December 31, 2009, Southern had not issued and does not expect to issue any FDIC-guaranteed debt under the TLGP. Southern's additional FDIC fee assessment in 2009 related to the full deposit coverage for NOW accounts paying less than 0.5% interest per annum and IOLTA was $7,100.

          In addition, the U.S. Government, the Federal Reserve, the Department of the Treasury, the FDIC and other governmental and regulatory bodies have taken, or may be considering taking, other actions to address the financial crisis. There can be no assurance, however, as to the actual impact of these actions on the financial markets and their potential impact on our business.

          Southern

          Southern is subject to supervision and regulation by the Federal Reserve System. Our activities are generally limited to owning or controlling banks and engaging in such other activities as the Federal Reserve System may determine to be closely related to banking. Prior approval of the Federal Reserve System, and in some cases various other government agencies, is required for us to acquire control of any additional bank holding companies, banks or other operating subsidiaries. We are subject to periodic examination by the Federal Reserve System, and are required to file with the Federal Reserve System periodic reports of our operations and such additional information as the Federal Reserve System may require.

          Southern is a legal entity separate and distinct from the Bank. There are legal limitations on the extent to which the Bank may lend or otherwise supply funds to us. Payment of dividends to us by the Bank, our principal source of funds, is subject to various state and federal regulatory limitations. Under the Michigan Banking Code of 1999, the Bank's ability to pay dividends to us is subject to the following restrictions:

          Federal law generally prohibits a bank from making any capital distribution (including payment of a dividend) or paying any management fee to its parent company if the depository institution would thereafter be undercapitalized. The FDIC may prevent an insured bank from paying dividends if the bank is in default of payment of any assessment due to the FDIC. In addition, the FDIC may prohibit the payment of dividends by a bank, if such payment is determined, by reason of the financial conditions of the bank, to be an unsafe and unsound banking practice. Additional information on restrictions on payment of dividends by the banks may be found under "Management's Discussion and Analysis of Financial Condition and Results of Operations" and Note Q of our consolidated financial statements, which information is here incorporated by reference.

          Under Federal Reserve System policy, we are expected to act as a source of financial strength to the Bank and to commit resources to support the Bank. In addition, if the Michigan Office of Financial and Insurance Regulation ("OFIR") deems the Bank's capital to be impaired, OFIR may require the Bank to restore its capital by a special assessment on us as the Bank's only shareholder. If we failed to pay any assessment, our directors would be required, under Michigan law, to sell the shares of the Bank's stock owned by us to the highest bidder at either a public or private auction and use the proceeds of the sale to restore the Bank's capital.

          The Federal Reserve Board and the FDIC have established guidelines for risk-based capital by bank holding companies and banks. These guidelines establish a risk-adjusted ratio relating capital to risk-weighted assets and off-balance-sheet exposures. These capital guidelines primarily define the components of capital, categorize assets into different risk classes, and include certain off-balance-sheet items in the calculation of capital requirements.

          The FDIC Improvement Act of 1991 established a system of prompt corrective action to resolve the problems of undercapitalized financial institutions. Under this system, federal banking regulators have established five capital categories: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized, in which all institutions are placed. The federal banking agencies have also specified by regulation the relevant capital levels for each of the categories.

          Federal banking regulators are required to take specified mandatory supervisory actions and are authorized to take other discretionary actions with respect to institutions in the three undercapitalized categories. The severity of the action depends upon the capital category in which the institution is placed. Subject to a narrow exception, the banking regulator must generally appoint a receiver or conservator for an institution that is critically undercapitalized. An institution in any of the under-capitalized categories is required to submit an acceptable capital restoration plan to its appropriate federal banking agency. An undercapitalized institution is also generally prohibited from paying any dividends, increasing its average total assets, making acquisitions, establishing any branches or engaging in any new line of business, except under an accepted capital restoration plan or with FDIC approval.

          Failure to meet capital guidelines could subject a bank or bank holding company to a variety of enforcement remedies, including issuance of a capital directive, the termination of deposit insurance by the FDIC, a prohibition on accepting brokered deposits, and other restrictions on its business. In addition, such a bank would generally not receive regulatory approval of any application that requires the consideration of capital adequacy, such as a branch or merger application, unless the bank could demonstrate a reasonable plan to meet the capital requirement within a reasonable period of time.

          As of the date of this report, the capital ratios of Southern and the Bank exceeded the minimum thresholds to be categorized as "well-capitalized" under applicable regulations. Note V of our consolidated financial statements provides additional information regarding our capital ratios, and is here incorporated by reference.

          Southern Michigan Bank

          Southern Michigan Bank is chartered under Michigan law and is subject to regulation by OFIR. Michigan banking laws place restrictions on various aspects of banking, including permitted activities, loan interest rates, branching, payment of dividends, and capital and surplus requirements.

          The Bank's deposits are insured by the FDIC to the extent provided by law. From time to time, the Bank is required to pay deposit insurance premiums to the Deposit Insurance Fund ("DIF"). The amount of the premiums varies and are generally determined by the FDIC based on the balance of insured deposits and the amount of risk each institution poses to the DIF. The Bank is a member of the Federal Home Loan Bank system. This provides certain advantages, including favorable borrowing rates for certain funds.

          Pursuant to the Federal Deposit Insurance Reform Act of 2005, the FDIC modified its method of calculating FDIC insurance assessments effective November 2006, and provided credits to certain banks for the calendar year 2007, to be applied to future assessments. The bank had earned assessment credits.  These changes allowed the Bank to partially offset its FDIC insurance assessments for 2007 and much of 2008 using credits they have earned. Credits at the Bank were used up during 2008. The assessment methodology allows the FDIC to set its assessment rates in the future in connection with declines in the insurance funds or increases in the amount of insurance coverage.

          During 2008, the Bank paid $45,000 in Financing Corporation ("FICO") assessments related to outstanding FICO bonds to the FDIC as collection agent. The FICO is a mixed-ownership government corporation established by the Competitive Equality Banking Act of 1987 whose sole purpose was to function as a financing vehicle for the now defunct Federal Savings and Loan Insurance Corporation. FICO assessments will continue in the future for the Bank.

          Banks are subject to a number of federal and state laws and regulations, which have a material impact on their business. These include, among others, minimum capital requirements, state usury laws, state laws relating to fiduciaries, the Truth in Lending Act, the Truth in Savings Act, the Equal Credit Opportunity Act, the Fair Credit Reporting Act, the Expedited Funds Availability Act, the Community Reinvestment Act, the Real Estate Settlement Procedures Act, the USA PATRIOT Act, the FACT Act, the Gramm-Leach-Bliley Act, the Sarbanes-Oxley Act, The Bank Secrecy Act, electronic funds transfer laws, redlining laws, predatory lending laws, antitrust laws, environmental laws, money laundering laws and privacy laws. The instruments of monetary policy of authorities,

such as the Federal Reserve System, may influence the growth and distribution of bank loans, investments and deposits, and may also affect interest rates on loans and deposits. These policies may have a significant effect on the operating results of banks.

          Bank holding companies may acquire banks and other bank holding companies located in any state in the United States without regard to geographic restrictions or reciprocity requirements imposed by state banking law. Banks may also establish interstate branch networks through acquisitions of and mergers with other banks. The establishment of de novo interstate branches or the acquisition of individual branches of a bank in another state (rather than the acquisition of an out-of-state bank in its entirety) is allowed only if specifically authorized by state law.

          Michigan banking laws do not significantly restrict interstate banking. The Michigan Banking Code of 1999 permits, in appropriate circumstances and with the approval of the Office of Financial and Insurance Regulation, (1) acquisition of Michigan banks by FDIC-insured banks, savings banks or savings and loan associations located in other states, (2) sale by a Michigan bank of branches to an FDIC-insured bank, savings bank or savings and loan association located in a state in which a Michigan bank could purchase branches of the purchasing entity, (3) consolidation of Michigan banks and FDIC-insured banks, savings banks or savings and loan associations located in other states having laws permitting such consolidation, (4) establishment of branches in Michigan by FDIC-insured banks located in other states, the District of Columbia or U.S. territories or protectorates having laws permitting a Michigan bank to establish a branch in such jurisdiction, and (5) establishment by foreign banks of branches located in Michigan. A Michigan bank holding company may acquire a non-Michigan bank and a non-Michigan bank holding company may acquire a Michigan bank.

Environmental Regulations

          In our business, we hold title on a temporary or permanent basis, to a number of parcels of real property. These include properties owned for branch offices and other business purposes and properties taken in or in lieu of foreclosure to satisfy loans in default. Under current federal laws, present and past owners of real property are exposed to liability for the cost of cleanup of contamination on or originating from those properties, even if they are wholly innocent of the actions that caused the contamination. These liabilities can be material and can exceed the value of the contaminated property. Although management is currently aware of no such environmental liabilities attributable to us or any of our properties, any such liabilities could have a material adverse effect on our capital expenditures, earnings, or competitive position.

Employees

          As of December 31, 2009, Southern Michigan Bank employed 209 total employees equaling 196 full-time equivalent employees. Southern's only employees as of the same date were its four executive officers (all of whom were also employed by Southern Michigan Bank).

Statistical Information

          Additional statistical information describing our business appears in the following pages and in Management's Discussion and Analysis of Financial Condition and Results of Operations and in our consolidated financial statements and related notes contained in this report.

          Southern acquired FNB Financial Corporation on December 1, 2007. Statistical information presented for 2009, 2008 and 2007 includes information for FNB Financial Corporation from the date of acquisition. Any comparison of information from 2009, 2008 or 2007 to information in previous years must consider that information for FNB Financial Corporation is not included in information presented for periods before December 1, 2007.

          Securities Portfolio

          The book value of securities categorized by type at December 31 was as follows:

          At the end of 2009 and 2008, the market value of securities issued by the State of Michigan and all its political subdivisions totaled $15,466,000 and $16,872,000, respectively. No other securities held of any other single issuer were greater than 10% of shareholders' equity.

          Presented below is the fair value of securities as of December 31, 2009 and 2008, a schedule of maturities of securities as of December 31, 2009, and the weighted average yields of securities as of December 31, 2009.

______________

          The weighted average yields are based on coupon rates for securities purchased at par value and on effective interest rates considering amortization or accretion if the securities were purchased at a premium or discount.

          Loan Portfolio

          Our combined loan portfolio, categorized by loan type (excluding loans held for sale) as of December 31 is presented below.

          We have no foreign loans.

Maturities and Sensitivities of Loans to Changes in Interest Rates

          The following schedule presents the maturities of loans (excluding residential real estate and consumer loans) as of December 31, 2009. All loans over one year in maturity (excluding residential real estate and consumer loans) are also presented classified according to the sensitivity to changes in interest rates as of December 31, 2009.

          Risk Elements

          The objective of our credit risk strategy is to quantify and manage credit risk on an aggregate portfolio basis, and to limit the risk of loss resulting from an individual customer default. This strategy has not changed over the past three years. Such strategy is based on three core principles: conservatism, diversification and monitoring. We believe that effective credit risk management begins with conservative lending practices. These practices include conservative underwriting, documentation, monitoring and collection standards. Our credit risk strategy also emphasizes diversification on an industry and customer level, regular credit examinations, and monthly management reviews of large credit exposures and credits experiencing deterioration of credit quality. Lending activities are centralized, with lending officers delegated specific authority amounts. We have annual independent reviews of the quality of our underwriting and documentation and the accuracy of risk grades.

          Our credit review process and overall assessment of required allowances are based on ongoing quarterly assessments of the probable estimated losses inherent in our loan portfolio. We use these assessments to promptly identify potential problem loans within the portfolio, maintain an allowance for losses we believe to be adequate and take any necessary charge-offs. In addition to the individual review of larger commercial loans that exhibit probable or observed credit weaknesses, the commercial credit review includes the use of a risk grading system.

          Loan originations are developed from a number of sources, including continuing business with depositors, borrowers and real estate developers, advertisements, solicitations by lending staff, walk-in customers, director referrals, and loan participations purchased from other financial institutions.

          Commercial and agricultural loans. We make loans for commercial purposes to sole proprietorships, partnerships, corporations and other business enterprises. We make agricultural loans for the purpose of financing agricultural production, including all costs associated with growing crops or raising livestock. Commercial and agricultural loans may be secured, other than by real estate, or unsecured, requiring one single payment or on an installment repayment schedule. Commercial and agricultural loans generally have final maturities of five years or less and are made with either fixed interest rates or rates that adjust based upon the national prime rate in effect at the time of the rate change.

          Commercial and agricultural lending involves certain risks relating to changes in local and national economic conditions and the resulting effect on commercial or agricultural borrowers. Such loans are subject to greater risk of default during periods of adverse economic conditions. Because such loans may be secured by equipment, inventory, accounts receivable and other non-real estate assets, the collateral may not be sufficient to ensure full payment of the loan in the event of a default. To reduce such risk, we may obtain the personal guarantees of one or more of the principals of the borrowers.

          Real estate - commercial loans. We make non-residential real estate loans secured by first mortgages and/or junior mortgages on non-residential real estate, including retail stores, office buildings, warehouses, apartment buildings, and other commercial properties. These loans typically have a higher degree of risk than residential lending. The increased risk is due primarily to the dependence of the borrower on the cash flow from the property or the business operated on the property to service the loan.

          Real estate - residential loans. We make residential real estate loans secured by first mortgages on one-to-four family residences, with a majority being single family residences. These loans are typically limited in relationship to the appraised value of the real estate and improvements at the time of origination of the loan.

          Real estate - construction. Construction loans are made to finance land development before erecting new structures and to finance the construction of new buildings or additions to existing buildings. Many of the construction loans we make are to owner occupants for the construction of single family homes. Other loans we make are to builders and developers for various projects.

          Consumer loans. We make a variety of consumer loans to individuals for family, household and other personal purposes. We make these loans for the purpose of financing the purchase of vehicles or furniture, educational expenses, medical expenses or vacation expenses, and other consumer purposes. Consumer loans may be secured, other than by real estate, or unsecured, generally requiring repayment on an installment repayment schedule.

          The following were classified as non-accrual, past due and restructured loans as of December 31:

          A loan is placed on nonaccrual status at the point in time at which the collectability of principal or interest is considered doubtful. The table below illustrates interest forgone and interest recorded on nonperforming loans for the years presented.

          Potential Problem Loans

          At December 31, 2009, there were $37.9 million of loans where some concern existed as to the borrowers' abilities to comply with original loan terms. We allocated $1,550,000 in the aggregate for loan losses for nonperforming and potential problem loans as of December 31, 2009. However, our entire allowance for loan losses is also available for potential problem loans.

          Loan Concentrations

          As of December 31, 2009, there was no concentration of loans exceeding 10% of total loans which are not otherwise disclosed as a category of loans pursuant to Item III.A. of Industry Guide 3.

          Summary of Loan Loss Experience

          The following schedule presents a summary of activity in the allowance for loan losses for the periods shown and the percentage of net charge-offs during each period to average gross loans outstanding during the period.

          The following schedule presents an allocation of the allowance for loan losses to the various loan categories as of December 31 of each year presented.

          The Securities and Exchange Commission's Industry Guide 3 provides for a break down of the allowance for loan losses into major loan categories. We allocate the allowance among the various categories through an analysis of the loan portfolio composition, prior loan loss experience, evaluation of those loans identified as being probable problems in collection, results of examination by regulatory agencies and current economic conditions. The entire allowance is available to absorb any losses without regard to the category or categories in which the charged off loans are classified.

Risks Related to Southern's Business

The state of financial markets and the economy may adversely affect our sources of liquidity and capital.

          There has been significant recent turmoil and volatility in worldwide and national financial markets which is, at present, ongoing. These conditions have resulted in a disruption in the liquidity of financial markets, and could directly impact us if we need to access capital markets to raise capital to support our business and could impact our overall liquidity position. This situation could affect the cost of funds or our ability to raise funds. If we were unable to access capital or funding sources when needed, it could adversely impact our financial condition, results of operations, cash flows, and level of regulatory capital.

Restrictions on the Bank's ability to pay dividends subjects Southern to liquidity risk.

          Southern's principal source of funds to pay cash dividends and to fund its corporate obligations is the earnings of and dividends paid by the Bank. Southern's corporate obligations include its obligation to pay interest and principal when and as due under its bank credit agreement, which is secured by a pledge of all of the stock of the Bank, and its obligation to pay interest and principal when due under its junior subordinated debt securities. If the Bank is unable to pay cash dividends to Southern in an amount sufficient to fund these obligations and Southern is unable to access liquidity from other sources, Southern may be unable to pay dividends and satisfy its other financial obligations. As of January 1, 2010, the Bank could pay $3.7 million of dividends to Southern without prior regulatory approval and Southern had limited liquid assets. Additional information related to the liquidity position of Southern may be found in Notes Q and R to the consolidated financial statements.

The Bank is subject to liquidity risk in its operations, which could adversely affect its ability to fund various obligations.

          Liquidity risk is the possibility of being unable to meet obligations as they come due, capitalize on growth opportunities as they arise, or pay regular dividends because of an inability to liquidate assets or obtain adequate funding on a timely basis, at a reasonable cost and within acceptable risk tolerances.  Liquidity is required to fund various obligations, including credit obligations to borrowers, mortgage originations, withdrawals by depositors, repayment of debt, dividends to the Bank's shareholder, operating expenses and capital expenditures.  The Bank's liquidity is derived primarily from retail deposit growth and retention, principal and interest payments on loans and investment securities, net cash provided from operation and access to other funding sources.  Liquidity is essential to the Bank's business. The Bank must maintain sufficient funds to respond to the needs of depositors and borrowers.

An inability to raise funds through deposits, borrowings, the sale or pledging as collateral of loans and other assets could have a material adverse effect on the Bank's liquidity. The Bank's access to funding sources in amounts adequate to finance its activities could be impaired by factors that affect the Bank specifically or the financial services industry in general. Factors that could detrimentally impact the Bank's access to liquidity sources include a decrease in the level of the Bank's business activity due to a market down turn or regulatory action that limits or eliminates the Bank's access to alternate funding sources. The Bank's ability to borrow could also be impaired by factors that are nonspecific to the Bank, such as severe disruption of the financial markets or negative expectations about the prospects for the financial services industry as a whole, as evidenced by recent turmoil in the domestic and worldwide credit markets.

If the Transaction Account Guaranty Program of the FDIC's Temporary Liquidity Guarantee Program expires on June 30, 2010 as currently scheduled, then the Bank could experience a significant reduction in uninsured deposits, which could adversely affect the Bank's liquidity position.

          The Transaction Account Guaranty Program ("TAG") of the FDIC's Temporary Liquidity Guarantee Program temporarily insured non-interest bearing deposits without limitation. TAG is schedule to expire on June 30, 2010 with insured levels on non-interest bearing deposits returning to normal levels. The Bank is a participant in TAG. If TAG expires as scheduled, the Bank could experience a significant reduction in previously insured but then uninsured deposits, which could adversely affect the Bank's liquidity position. Recent media reports indicate that the FDIC is considering extending TAG beyond June 30, 2010, but there is no assurance that the FDIC will do so.

If Southern's allowance for loan losses is not sufficient to cover actual loan losses, Southern's earnings could decrease.

          Southern's loan customers may not repay their loans according to the terms of these loans, and the collateral securing the payment of these loans may be insufficient to assure repayment. Southern may experience significant loan losses, which could have a material adverse effect on its operating results. Southern's management makes various assumptions and judgments about the collectibility of Southern's loan portfolio, including the creditworthiness of its borrowers and the value of the real estate and other assets serving as collateral for the repayment of many of Southern's loans. Southern maintains an allowance for loan losses to cover loan losses that may occur. In determining the size of the allowance, Southern relies on an analysis of its loan portfolio based on historical loss experience, volume and types of loans, trends in classification, volume and trends in delinquencies and non-accruals, national and local economic conditions, and other pertinent information.

          If Southern's assumptions are wrong, its current allowance may not be sufficient to cover loan losses, and adjustments may be necessary to allow for different economic conditions or adverse developments in Southern's loan portfolio. Material increases to Southern's allowance would materially decrease its net income and could materially decrease shareholders' equity.

          In certain situations, where collection efforts are unsuccessful or acceptable work-out arrangements cannot be reached, Southern may have to write off certain loans in whole or in part. In such situations, Southern may acquire real estate or other assets, if any, which secure the loans through foreclosure or other similar available remedies. In such cases, the amount owed under the defaulted loan often exceeds the value of the assets acquired.

          In addition, federal and state regulators periodically review Southern's allowance for loan losses and may require Southern to increase its provision for loan losses or recognize further loan charge-offs based on judgments different than those of Southern's management. Any increase in Southern's allowance for loan losses or loan charge-offs as required by these regulatory agencies could have a material negative effect on Southern's operating results and shareholders' equity.

Southern is subject to lending risk, which could materially adversely affect the Southern's results of operations and financial condition.

          There are inherent risks associated with the Southern's lending activities. These risks include, among other things, the impact of changes in interest rates and changes in the economic conditions in the markets where Southern operates. Increases in interest rates or weakening economic conditions could adversely impact the ability of borrowers to repay outstanding loans or the value of the collateral securing these loans, which could have a material adverse effect on the Southern's results of operations and financial condition.

Southern's loan portfolio includes a substantial percentage of commercial and industrial loans, which may be subject to greater risks than those related to residential loans.

          Southern's loan portfolio includes a substantial percentage of commercial and industrial loans. Commercial and industrial loans generally carry larger loan balances and involve a greater degree of financial and credit risks than home equity loans or residential mortgage loans. Any significant failure to pay on time by Southern's customers would hurt Southern's earnings. The increased financial and credit risk associated with these types of loans is a result of several factors, including the concentration of principal in a limited number of loans and borrowers, the size of loan balances, the effects of general economic conditions on income-producing properties, and the increased difficulty of evaluating and monitoring these types of loans. The repayment of loans secured by commercial real estate is typically dependent upon the successful operation of the related real estate or commercial project. If the cash flow from the project is reduced, the borrower's ability to repay the loan may be impaired. This cash flow shortage may result in the failure to make loan payments. In such cases, Southern may be compelled to modify the terms of the loan. In addition, the nature of these loans is such that they are generally less predictable and more difficult to evaluate and monitor. As a result, repayment of these loans may, to a greater extent than residential loans, be subject to adverse conditions in the real estate market or economy.

Southern is subject to interest rate risk, which may negatively affect Southern's earnings and the value of its assets.

          Southern's earnings and cash flows are largely dependent upon its net interest income. Net interest income is the difference between interest income earned on interest-earning assets, such as loans and securities, and interest expense paid on interest-bearing liabilities, such as deposits and borrowed funds. Interest rates are highly sensitive to many factors that are beyond Southern's control, including general economic conditions and policies of various governmental and regulatory agencies and, in particular, the Federal Reserve Board. Changes in monetary policy, including changes in interest rates, could influence the interest Southern receives on loans and securities and the amount of interest it pays on deposits and borrowings. Such changes could also affect Southern's ability to originate loans and obtain deposits and the fair value of Southern's financial assets and liabilities. If the interest rates paid on deposits and other borrowings increase at a faster rate than the interest rates received on loans and other investments, Southern's net interest income, and therefore earnings, could be adversely affected. Earnings could also be adversely affected if the interest rates received on loans and other investments fall more quickly than the interest rates paid on deposits and other borrowings.

Loss of Southern's Chief Executive Officer or other executive officers could adversely affect its business.

          Southern's success is dependent upon the continued service and skills of its executive officers and senior management. If Southern loses the services of these key personnel, it could have a negative impact on Southern's business because of their skills, years of industry experience and the difficulty of promptly finding qualified replacement personnel. The services of John H. Castle, Southern's Chairman and Chief Executive Officer, Kurt G. Miller, Southern's President, and Danice L. Chartrand, Southern's Chief Financial Officer, would be particularly difficult to replace.

Southern's continued growth may require it to raise additional capital in the future, but that capital might not be available on acceptable terms when it is needed.

          Southern is required by federal and state regulatory authorities to maintain adequate levels of capital to support its operations. Southern expects that it may need to raise additional capital to maintain its regulatory capital at desired levels or support its continued growth. Southern's ability to raise additional capital will depend on conditions in the capital markets at that time, which are outside Southern's control, and on its financial performance. Southern cannot assure you of its ability to raise additional capital on terms acceptable to Southern. If Southern cannot raise additional capital when needed, its ability to maintain assets at current levels or further expand its operations through organic growth and acquisitions could be materially impaired.

Southern's business is subject to the success of the local economies where it operates.

          Southern's success significantly depends upon the economy, population, income levels, deposits and housing starts in the southwest Michigan market. If this market does not grow or if prevailing economic conditions

locally or nationally are unfavorable, Southern's business may be adversely affected. Adverse economic conditions in southern Michigan, including the loss of certain significant employers, could reduce Southern's growth rate, affect the ability of its customers to repay their loans to Southern, and generally adversely affect Southern's financial condition and results of operations. Southern is less able than a larger institution to spread the risks of unfavorable local economic conditions across a large number of diversified economies.

          Any adverse market or economic conditions in Michigan may disproportionately increase the risk that Southern's borrowers are unable to make their loan payments. In addition, the market value of the real estate securing loans as collateral could be adversely affected by unfavorable changes in market and economic conditions. A sustained period of increased payment delinquencies, foreclosures or losses caused by adverse market or economic conditions in the State of Michigan could adversely affect the value of Southern's assets, revenues, results of operations and financial condition.

          Commercial banks and other financial institutions are affected by economic and political conditions, both domestic and international, and by governmental monetary policies. Conditions such as inflation, recession, unemployment, high interest rates, short money supply, scarce natural resources, international disorders, terrorism and other factors beyond Southern's control may adversely affect profitability.

Southern may be required to pay additional insurance premiums to the FDIC, which could negatively impact earnings.

          Recent insured institution failures, as well as deterioration in banking and economic conditions, have significantly increased FDIC loss provisions, resulting in a decline in the designated reserve ratio to historical lows. The FDIC expects a higher rate of insured institution failures in the next few years compared to recent years; thus, the reserve ratio may continue to decline. In addition, the limit on FDIC coverage has been increased to $250,000 through December 31, 2013. These developments have caused the premiums assessed to Southern by the FDIC to increase. Further, depending upon any future losses that the FDIC insurance fund may suffer, there can be no assurance that there will not be additional premium increases in order to replenish the fund. The FDIC may need to set a higher base rate schedule or impose special assessments due to future financial institution failures and updated failure and loss projections. In addition, a decline in the Bank's CAMEL ratings could subject Southern to increased FDIC insurance premiums. Potentially higher FDIC assessment rates could have an adverse impact on Southern's results of operations.

Southern could be adversely affected by the soundness of other financial institutions, including defaults by larger financial institutions.

          Southern's ability to engage in routine funding transactions could be adversely affected by the actions and commercial soundness of other financial institutions. Financial services institutions are interrelated as a result of credit, trading, clearing, counterparty or other relationships between financial institutions. Southern has exposure to different counterparties, and Southern routinely executes transactions with counterparties in the financial industry. As a result, defaults by, or even rumors or questions about, one or more financial services institutions, or the financial services industry generally, have led to market-wide liquidity problems and could lead to losses or defaults by Southern or by other institutions. This is sometimes referred to as "systemic risk" and may adversely affect financial intermediaries, such as clearing agencies, clearing houses, banks, securities firms and exchanges, with which Southern interacts on a daily basis, and therefore could adversely affect Southern.

          Many of these transactions expose Southern to credit risk in the event of default of a counterparty. In addition, Southern's credit risk may be exacerbated when the collateral held by Southern cannot be realized upon or is liquidated at prices not sufficient to recover the full amount of the financial instrument exposure due to Southern. There is no assurance that any such losses would not materially and adversely affect Southern's business, results of operations or financial condition.

Prepayments of loans may negatively impact Southern's business.

          Generally, customers of Southern may prepay the principal amount of their outstanding loans at any time. The speed at which such prepayments occur, as well as the size of such prepayments, are within such customers' discretion. If customers prepay the principal amount of their loans, and Southern is unable to lend those funds to other borrowers or invest the funds at the same or higher interest rates, Southern's interest income will be reduced. A

significant reduction in interest income could have a negative impact on Southern's results of operations and financial condition.

Competition from competing financial institutions and other financial service providers may adversely affect Southern's profitability.

          The banking business is highly competitive and Southern experiences competition in each of its markets from many other financial institutions. Southern competes with commercial banks, credit unions, savings and loan associations, mortgage banking firms, consumer finance companies, securities brokerage firms, insurance companies, money market funds, and other mutual funds, as well as other super-regional, and national financial institutions that operate offices in Southern's primary market areas and elsewhere. In addition, some of the institutions that Southern competes against are not subject to the same regulatory restrictions as Southern, and accordingly, may have certain, inherent, cost advantages.

          Southern competes with these institutions both in attracting deposits and in making loans. Price competition for loans might result in Southern originating fewer loans, or earning less on its loans, and price competition for deposits might result in a decrease in Southern's total deposits or higher rates on its deposits. In addition, Southern has to attract its customer base from other existing financial institutions and from new residents. Many of Southern's competitors are larger financial institutions. While Southern believes it can and does successfully compete with these other financial institutions in its primary markets, Southern may face a competitive disadvantage as a result of its smaller size, lack of geographic diversification, and inability to spread its marketing costs across a broader market. Although Southern competes by concentrating its marketing efforts in its primary markets with local advertisements, personal contacts, and greater flexibility and responsiveness in working with local customers, Southern can give no assurance that this strategy will be successful.

Southern is subject to extensive regulation that could limit or restrict its activities.

          Southern operates in a highly regulated industry and is subject to examination, supervision, and comprehensive regulation by various federal and state agencies. Southern's compliance with these regulations is costly and restricts certain of its activities, including payment of dividends, mergers and acquisitions, investments, loans and interest rates charged, interest rates paid on deposits and locations of offices. Southern is also subject to capitalization guidelines established by its regulators, which require Southern to maintain adequate capital to support its growth.

          The laws and regulations applicable to the banking industry could change at any time, and Southern cannot predict the effects of these changes on its business and profitability. Because government regulation greatly affects the business and financial results of all commercial banks and bank holding companies, Southern's cost of compliance could adversely affect its ability to operate profitably.

Future claims could be made against Southern or Southern Michigan Bank related to their relationship with Alanar, Inc. and its affiliates.

          Southern Michigan Bank previously served as indenture trustee and also was the depository bank in connection with certain bond offerings underwritten by Alanar, Inc. Southern Michigan Bank also was party to an agreement with Guardian Services, LLC, an affiliate of Alanar, Inc., to provide fiduciary oversight services related to the custodianship of certain individual retirement accounts that invested in bonds underwritten by Alanar, Inc. On July 26, 2005, the SEC obtained a court order freezing all assets under the control of Alanar, Inc., Guardian Services, LLC, and their affiliates, including all accounts at Southern Michigan Bank. Alanar, Inc., Guardian Services, LLC, and their affiliates have been under court-appointed monitorship since July 26, 2005 and in receivership since December 20, 2005. The SEC and the receiver alleged that Alanar, Inc., Guardian Services, LLC, and their affiliates engaged in fraud and other improper conduct to hide bond defaults in connection with over 340 bond offerings. Southern Michigan Bank has not served as indenture trustee since November 16, 2006, when the court approved the removal of Southern Michigan Bank as trustee so that the receiver could assume this role to promote efficiency in the administration of the receivership. No claims with respect to this matter have been filed against Southern or Southern Michigan Bank by any person or entity. There can be no assurance, however, that Southern or Southern Michigan Bank will not be subject to future claims arising out of their relationship with Alanar, Inc. and Guardian Services, LLC. Protracted litigation or an adverse decision or settlement of any such action or

proceeding could have a material adverse effect on the financial position, business, prospects, and results of operation of Southern or Southern Michigan Bank.

Evaluation of investment securities for other-than-temporary impairment involves subjective determinations and could materially impact Southern's results of operations and financial condition.

          The evaluation of impairments is a quantitative and qualitative process, which is subject to risks and uncertainties and is intended to determine whether declines in the fair value of investments should be recognized in current period earnings. The risks and uncertainties include changes in general economic conditions, the issuer's financial condition or future recovery prospects, the effects of changes in interest rates or credit spreads and the expected recovery period. Estimating future cash flows involves incorporating information received from third-party sources and making internal assumptions and judgments regarding the future performance of the underlying collateral and assessing the probability that an adverse change in future cash flows has occurred. The determination of the amount of other-than-temporary impairments is based upon Southern's periodic evaluation and assessment of known and inherent risks associated with the respective asset class. Such evaluations and assessments are revised as conditions change and new information becomes available. Southern's management considers a wide range of factors about the security issuer and uses its reasonable judgment in evaluating the cause of the decline in the estimated fair value of the security and in assessing the prospects for recovery. Inherent in management's evaluation of the security are assumptions and estimates about the operations of the issuer and its future earnings potential. Impairments to the carrying value of our investment securities may need to be taken in the future, which could have a material adverse effect on our results of operations and financial condition.

If Southern is required to write down goodwill and other intangible assets, its financial condition and results of operations would be negatively affected.

          A substantial portion of the value of the merger consideration paid in connection with the merger of FNB Financial Corporation was allocated to goodwill and other intangible assets on Southern's consolidated balance sheets. The amount of the purchase price that is allocated to goodwill and other intangible assets is determined by the excess of the purchase price over the net identifiable assets acquired. Southern is required to conduct an annual review to determine whether goodwill and other identifiable intangible assets are impaired.

          Goodwill is tested for impairment annually in the fourth quarter. An impairment test also could be triggered between annual testing dates if an event occurs or circumstances change that would more likely than not reduce the fair value below the carrying amount. Examples of those events or circumstances would include a significant adverse change in business climate; a significant unanticipated loss of clients/assets under management; an unanticipated loss of key personnel; a sustained period of poor investment performance; a significant loss of deposits or loans; a significant reduction in profitability; or a significant change in loan credit quality.

          Southern cannot assure you that it will not be required to take an impairment charge in the future. Any material impairment charge would have a negative effect on Southern's financial results and shareholders' equity.

If Southern is required to take a valuation allowance with respect to its deferred tax assets, its financial condition and results of operations would be negatively affected.

          Southern's net deferred tax asset was $1.76 million at December 31, 2009. A valuation allowance related to deferred tax assets is required when it is considered more likely than not that all or part of the benefit related to such assets will not be realized. A valuation allowance of $54,000 was considered necessary at December 31, 2009 and 2008 as the likelihood of receiving a tax benefit on a portion of the capital loss on the write off of an investment was considered doubtful. If Southern is required in the future to take one or more additional valuation allowances with respect to its deferred tax assets, its financial condition and results of operations would be negatively affected.

If Southern is required to take a valuation allowance with respect to its mortgage servicing rights, its financial condition and results of operations would be negatively affected.

Southern's mortgage servicing rights were $753,000 at December 31, 2009. No valuation allowance for capitalized mortgage servicing rights was necessary at December 31, 2009 or 2008 because the fair value of such rights approximated or exceeded the carrying value. If Southern is required in the future to take a valuation

allowance with respect to its mortgage servicing rights, its financial condition and results of operations would be negatively affected.

Southern depends upon the accuracy and completeness of information about customers.

          In deciding whether to extend credit to customers, Southern may rely on information provided to it by its customers, including financial statements and other financial information. Southern may also rely on representations of customers as to the accuracy and completeness of that information and, with respect to financial statements, on reports of independent auditors. Southern's financial condition and results of operations could be negatively impacted to the extent that Southern extends credit in reliance on financial statements or other information provided by customers that is false or misleading.

Southern may be a defendant in a variety of litigation and other actions, which may have a material adverse effect on Southern's financial condition and results of operations.

          Southern and its subsidiaries may be involved from time to time in a variety of litigation arising out of its business. Southern's insurance may not cover all claims that may be asserted against it, and any claims asserted against it, regardless of merit or eventual outcome, may harm its reputation or cause it to incur unexpected expenses, which could be material in amount. Should the ultimate expenses, judgments or settlements in any litigation exceed Southern's insurance coverage, they could have a material adverse effect on Southern's financial condition and results of operations. In addition, Southern may not be able to obtain appropriate types or levels of insurance in the future, nor may it be able to obtain adequate replacement policies with acceptable terms, if at all. For additional information on legal matters, see Item 3 of this report.

Environmental liability associated with commercial lending could result in losses.

          In the course of its business, Southern may acquire, through foreclosure, properties securing loans it has originated or purchased that are in default. Particularly in commercial real estate lending, there is a risk that hazardous substances could be discovered on these properties. In this event, Southern might be required to remove these substances from the affected properties at Southern's sole cost and expense. The cost of this removal could substantially exceed the value of affected properties. Southern may not have adequate remedies against the prior owner or other responsible parties and could find it difficult or impossible to sell the affected properties. These events could have an adverse effect on Southern's business, results of operations and financial condition.

Attractive acquisition opportunities may not be available to Southern in the future, which may negatively impact Southern's ability to grow its business and effectively compete in existing and new markets.

          Southern will continue to consider the acquisition of other businesses. However, Southern may not have the opportunity to make suitable acquisitions on favorable terms in the future. Southern expects that other banking and financial companies, many of which have significantly greater resources than Southern does, will compete with Southern to acquire compatible businesses. This competition could increase prices for acquisitions that Southern might likely pursue. Also, acquisitions of regulated businesses, such as banks, are subject to various regulatory approvals. Failure to maintain regulatory compliance with the various regulations applicable to Southern could make regulatory approvals difficult to obtain. If Southern fails to receive the appropriate regulatory approvals, Southern will not be able to consummate an acquisition that Southern believes is in its best interests.

Southern may face risks with respect to future expansion and acquisitions or mergers, which include substantial acquisition costs, an inability to effectively integrate an acquired business into Southern's operations, lower than anticipated profit levels, and economic dilution to shareholders.

          Southern may seek to acquire other financial institutions or parts of those institutions and may engage in de novo branch expansion in the future. Southern may also consider and enter into new lines of business or offer new products or services. Southern may incur substantial costs to expand. An expansion may not result in the levels of profits it seeks or levels of profits comparable to or better than Southern's historical experience. Integration efforts for any future mergers or acquisitions may not be successful, which could have a material adverse effect on Southern's operations and financial condition. Also, Southern may issue equity securities, including Southern common stock and securities convertible into shares of Southern common stock, in connection with future acquisitions, which could cause ownership and economic dilution to its current shareholders.

Changes in accounting standards could impact Southern's reported earnings.

          Current accounting and tax rules, standards, policies and interpretations influence the methods by which financial institutions conduct business and govern financial reporting and disclosures. These laws, regulations, rules, standards, policies and interpretations are constantly evolving and may change significantly over time. Events that may not have a direct impact on Southern, such as bankruptcy of major U.S. companies, have resulted in legislators, regulators, and authoritative bodies, such as the Financial Accounting Standards Board, the Securities Exchange Commission, the Public Company Accounting Oversight Board and various taxing authorities, responding by adopting and/or proposing substantive revision to laws, regulations, rules, standards, policies and interpretations. New accounting pronouncements and varying interpretations of accounting pronouncements have occurred and may occur in the future. Southern's financial condition and results of operations may be adversely affected by a change in accounting standards.

We continually encounter technological change, and we may have fewer resources than our competitors to continue to invest in technological improvements.

          The banking industry is undergoing rapid technological changes with frequent introductions of new technology-driven products and services. In addition to better serving customers, the effective use of technology increases efficiency and enables financial institutions to reduce costs. Our future success will depend, in part, on our ability to address the needs of our customers by using technology to provide products and services that will satisfy customer demands for convenience as well as to create additional efficiencies in our operations. Many of our competitors have substantially greater resources to invest in technological improvements. There can be no assurance that we will be able to effectively implement new technology-driven products and services or be successful in marketing such products and services to our customers.

Southern's controls and procedures may fail or be circumvented.

          Management regularly reviews and updates Southern's internal controls, disclosure controls and procedures, and corporate governance policies and procedures. Any system of controls, however well designed and operated, is based in part on certain assumptions and can provide only reasonable, not absolute, assurances that the objectives of the system are met. Any failure or circumvention of Southern's controls and procedures or failure to comply with regulations related to controls and procedures could have a material adverse effect on Southern's business, results of operations and financial condition.

Risks Associated with Southern Common Stock

There is not an active public trading market for Southern common stock.

          Southern common stock is traded in the OTC Bulletin Board market. Transactions in the stock are relatively infrequent. Southern does not expect an active trading market for Southern common stock to develop in the near future.

Southern's ability to pay dividends is limited and Southern may be unable to pay future dividends.

          Southern's ability to pay dividends is limited by regulatory restrictions and the need to maintain sufficient consolidated capital. The ability of the Bank to pay dividends to Southern is limited by its obligations to maintain sufficient capital and by other general restrictions on dividends that are applicable to the Bank. If Southern or its subsidiary banks do not satisfy these regulatory requirements, Southern would be unable to continue to pay dividends on its common stock. As of January 1, 2010, the Bank was able to pay $3.7 million in dividends to Southern without prior regulatory approval. Additional information on restrictions on payment of dividends by the banks may be found under "Management's Discussion and Analysis of Financial Condition and Results of Operations" and Note Q of our consolidated financial statements, which information is here incorporated by reference.

Southern may issue additional shares of its common stock in the future, which would dilute a shareholder's ownership of Southern common stock if the shareholder did not, or was not permitted to, invest in the additional issuances.

          Southern's articles of incorporation authorize its board of directors, without shareholder approval, to, among other things, issue additional common stock. The issuance of any additional shares of Southern common stock could be substantially dilutive to a shareholder's ownership of Southern common stock. To the extent that Southern issues convertible securities, stock appreciation rights, options or warrants to purchase Southern common stock in the future and those convertible securities, stock appreciation rights, options or warrants are exercised, Southern's shareholders may experience further dilution. Holders of shares of Southern common stock have no preemptive rights that entitle holders to purchase their pro rata share of any offering of shares of any class or series and, therefore, Southern's shareholders may not be permitted to invest in future issuances of Southern common stock.

Southern may issue debt and equity securities that are senior to Southern common stock as to distributions and in liquidation, which could negatively affect the value of Southern common stock.

          In the future, Southern may attempt to increase its capital resources by entering into debt or debt-like financing that is unsecured or secured by all or up to all of Southern's assets, or issuing debt or equity securities, which could include issuances of secured or unsecured commercial paper, medium-term notes, senior notes, subordinated notes, preferred stock or common stock. In the event of Southern's liquidation, its lenders and holders of its debt securities would receive a distribution of Southern's available assets before distributions to the holders of Southern common stock. Because Southern's decision to incur debt and issue securities in future offerings will depend on market conditions and other factors beyond Southern's control, Southern cannot predict or estimate the amount, timing or nature of its future offerings and debt financings. Further, market conditions could require Southern to accept less favorable terms for the issuance of its securities in the future. Thus, shareholders will bear the risk of Southern's future offerings reducing the value of their shares of Southern common stock and diluting their interest in Southern.

Unless a shareholder obtains prior consent from Southern, the shareholder will not be permitted to transfer to another party the shareholder's shares of Southern common stock if the party who would receive the shares would own of record fewer than 100 shares of Southern common stock.

          Southern's articles of incorporation provide that a shareholder may not transfer shares of Southern common stock without the consent of Southern, if, as a result of an attempted transfer, the party who would receive the shares would own fewer than 100 shares of Southern common stock. "Transfer" means any type of disposition, including a sale, gift, contribution, pledge, or other action that results in a change of record ownership of any share of Southern common stock. Southern may withhold its consent in its discretion. This restriction will limit the transferability of shares of Southern common stock and, unless a shareholder obtains Southern's prior consent, the shareholder will be prohibited from transferring fewer than 100 shares of Southern common stock if the party who would receive the shares would own of record fewer than 100 shares of Southern common stock.

          None.

          As of March 26, 2010, there were no material pending legal proceedings to which Southern or any of its subsidiaries were a party or to which any of their properties were subject, other than ordinary routine litigation incidental to the business of Southern and its subsidiaries.

Alanar, Inc.

          From approximately December 2001 through November 16, 2006, Southern Michigan Bank served as the indenture trustee on 49 bond offerings that were underwritten by Alanar, Inc. ("Alanar"), an Indiana broker-dealer firm specializing in bond offerings by churches. Southern Michigan Bank also served as the depository bank in connection with these 49 offerings, as well as an additional 35 bond offerings underwritten by Alanar for which Southern Michigan Bank was not the indenture trustee. Southern Michigan Bank also was party to an agreement dated December 27, 2000 with Guardian Services, LLC ("Guardian"), an affiliate of Alanar, pursuant to which Southern Michigan Bank agreed to provide fiduciary oversight services to Guardian and Guardian agreed to provide accounting, reporting and custodial services for individual retirement accounts.

          On July 26, 2005, the SEC obtained a court order freezing all assets under the control of Alanar, Guardian and their affiliates, including all accounts at Southern Michigan Bank. On October 5, 2005, the SEC issued an order finding that the defendants made misrepresentations to investors and misused investment proceeds from church bond issuances and the sale of bond investment fund units. The SEC revoked Alanar's registration as a broker and dealer and barred certain control persons from associating with any broker or dealer. Alanar, Guardian and their affiliates have been under court-appointed monitorship since July 26, 2005 and in receivership since December 20, 2005.

          In June 2006, the receiver filed a motion to have Southern Michigan Bank removed as indenture trustee for the purpose of avoiding inefficiencies and duplication of effort by both the receiver and Southern Michigan Bank. On November 17, 2006, pursuant to the receiver's unopposed motion, the court approved the removal of Southern Michigan Bank as indenture trustee for all bond offerings based upon the court's finding that "in light of the terms of the Receivership Order, as amended, Southern Michigan Bank is incapable of acting as trustee."

          On August 28, 2007, the court approved a plan for future distribution of the receivership assets. The court also issued certain findings of fact and conclusions of law, including finding that the offering documents prepared by Alanar to sell the bonds contained misrepresentations and omissions of material facts necessary for investors to make informed investment decisions. The court also found that there was inappropriate manipulation and commingling of funds, and that the failure to disclose this manipulation and commingling had all the essential elements of a Ponzi scheme. The receiver continues to administer the receivership assets pursuant to court approved plans for the receivership.

          No claims have been filed against Southern or Southern Michigan Bank by any bondholder, bond issuer, individual retirement account holder, the receiver, any governmental agency or any other person related to Southern Michigan Bank's former role as indenture trustee or Southern Michigan Bank's role as depository bank or in any other capacity related to these matters. There can be no assurance, however, that Southern or Southern Michigan Bank will not be subject to future claims, actions, suits or proceedings, including potential claims that our conduct was in breach of contractual, fiduciary or other duties or applicable statutes or regulations, or that, if made, Southern or Southern Michigan Bank would be successful in defending such claims. Protracted litigation or an adverse decision or settlement of any such action or proceeding could have a material adverse effect on the financial position, business, prospects and results of operations of Southern or Southern Michigan Bank.

          By SEC rule, Item 4 of Form 10-K has been removed and reserved.

This discussion should be read in conjunction with the consolidated financial statements and related notes to the consolidated financial statements.

Economic Trends

          The global and U.S. economies are experiencing significantly reduced business activity as a result of, among other factors, disruptions in the financial system during the past two years. Dramatic declines in the housing market during this time, along with falling home prices and increasing foreclosures and unemployment, have resulted in significant write-downs of asset values by financial institutions, including government-sponsored entities and major commercial and investment banks. These write-downs, initially of residential-related loans and mortgage-backed securities, but spreading to credit default swaps and other derivative securities, have caused many financial institutions to seek additional capital, to merge with larger and stronger institutions and, in some cases, to fail. Reflecting concern about the stability of the financial markets, many national and regional lenders have reduced, and in some cases, ceased to provide funding to borrowers, including other financial institutions. The availability of credit, confidence in the financial sector, and level of volatility in the financial markets have been significantly adversely affected as a result.

Market Developments

          Substantially all of the deposits of the Bank are insured up to applicable limits by the Deposit Insurance Fund ("DIF") of the FDIC and are subject to deposit insurance assessments to maintain the DIF. The FDIC utilizes a risk-based assessment system that imposes insurance premiums based upon a matrix that takes into account a bank's capital level and supervisory rating.

          On February 27, 2009, the FDIC adopted a final rule modifying the risk-based assessment system and setting initial base assessment rates beginning April 1, 2009, at 12 to 45 basis points; and due to extraordinary circumstances, extended the time within which the reserve ratio must be returned to 1.15 percent from five to seven years. On May 22, 2009, the FDIC adopted a final rule imposing a 5 basis point special assessment on each insured depository institution's assets minus Tier 1 capital as of June 30, 2009. The Bank incurred expenses of $217,000 as a result of the special assessment in the second quarter of 2009.

          On November 12, 2009, the FDIC amended its regulations requiring certain insured institutions to prepay their estimated quarterly risk-based assessments for the fourth quarter of 2009, and for all of 2010, 2011, and 2012. The prepaid assessment for these periods was collected on December 30, 2009, along with each institution's regular quarterly risk-based deposit insurance assessment for the third quarter of 2009. The total amount of FDIC prepayments for the Bank was $2.4 million. The prepayment relating to 2010-2012 has been treated as a prepaid expense on the books of SMB&T, and will be recognized as expense in the period for which the assessments are effective.

Results of Operations

          Southern's net income for 2009 was $1,936,000 compared to $813,000 in 2008, an increase of $1,123,000, or 138.1%. Provision for loan losses in the amount of $2,725,000 was expensed in 2009; down from $5,080,000 in 2008. Non-interest income of Southern, increased 12.7% to $7,172,000 in 2009. Non-interest expense of $18,970,000 in 2009 was equal to the 2008 expense.

          Results of operations can be measured by various ratio analyses. Two widely recognized performance indicators are return on average equity and return on average assets. Southern's return on average equity was 4.29% in 2009, 1.77% in 2008 and 12.72% in 2007. The return on average assets was 0.41 % in 2009, 0.17% in 2008 and 1.18% in 2007.

          Acquisition of FNB Financial Corporation and Consolidation of Banks

          On December 1, 2007, Southern acquired FNB Financial Corporation. The 2009 and 2008 results of operations include twelve months of combined financial results. The 2007 results of operations include one month of combined financial results after completion of the acquisition. The 2009 and 2008 year end balance sheets include all of the assets acquired and liabilities assumed from FNB Financial Corporation. Therefore, a comparison of 2008 to 2007 results of operations is materially affected as a result of the acquisition. For more detailed information concerning the acquisition, see Note C to the consolidated financial statements.

          In April 2009, FNB Financial (formerly, The First National Bank of Three Rivers) was consolidated with and into SMB&T.

          Net Interest Income

          Interest income is the total amount earned on funds invested in loans, investment securities and federal funds sold. Interest expense is the amount of interest paid on interest bearing checking and savings accounts, time deposits, short term advances, subordinated debentures and other long-term borrowings. Net interest income, on a fully taxable equivalent (FTE) basis, is the difference between interest income and interest expense adjusted for the tax benefit received on tax-exempt loan and investment securities. Net interest margin is calculated by dividing net interest income (FTE) by average interest earning assets. Net interest spread is the difference between the average yield on interest earning assets and the average cost of interest bearing liabilities. Because non-interest bearing sources of funds also support earning assets, the net interest margin exceeds the net interest spread.

          The presentation of net interest income on a FTE basis is not in accordance with GAAP but is customary in the banking industry. This non-GAAP measure ensures comparability of net interest income arising from both taxable and tax-exempt loans and investment securities. The adjustments to determine tax equivalent net interest income are itemized in Table 1 below.

          Net interest income is the most important source of Southern's earnings. Changes in Southern's net interest income are influenced by a number of factors, including changes in the level of interest earning assets, changes in the mix of interest earning assets and interest bearing liabilities, the level and direction of interest rates and the steepness of the yield curve.

          For 2009, Southern's net interest margin (FTE) was 4.14% compared to 4.36% for 2008 and 4.83% for 2007. Beginning with a 50 basis point drop in September 2007, the Federal Reserve began a campaign of decreasing overnight borrowing rates to stimulate the economy. Through December 2008, the Federal Reserve had decreased the overnight borrowing rate 5%, to its lowest level of all time, a range of 0% to .25%. For the entire year of 2009, these rate decreases impacted Southern's net interest margin. Southern's interest rate spread and margin both further decreased as yields on earning assets decreased 0.86%, from 6.31% to 5.45%, while deposit yields were down 0.71%, from 2.20% to 1.49%.

          In 2009, the lower interest margin resulted in $1,256,000 less net interest income than in 2008. The 2009 decrease was a result of lower rates being in effect for the entire year and reduced balances in loans and investment securities. Despite the lower net interest margin in 2008 and 2007, net interest income increased during both years by $3,055,000 and $508,000, respectively. The increase in both years primarily resulted from the acquisition of FNB.

          The 2008 increase was a result of $2,606,000 improvement in interest income and $449,000 reduction of interest expense. The increase in interest income was the result of $104.1 million of additional average earning assets, primarily from FNB, which was enough to overcome the rate decrease. Despite adding $103.6 million of average interest bearing deposits, primarily from FNB, interest expense decreased $449,000 in 2008 as Southern closely monitored deposit rates.

          The following table presents a summary of net interest income (FTE) for 2009, 2008 and 2007.
