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. Forward-looking statements are identifiable by words or phrases such as "outlook", or "strategy"; that an event or trend "may", "should", "will", "is likely", or is "probable" to occur or "continue" or "is scheduled" or "on track" or that Southern Michigan Bancorp, Inc. or its management "anticipates", "believes", "estimates", "plans", "forecasts", "intends", "predicts", "projects", or "expects" a particular result, or is "confident," "optimistic" or has an "opinion" that an event will occur, or other words or phrases such as "ongoing", "future", or "tend" and variations of such words and similar expressions. Management's determination of the provision and allowance for loan losses and other accounting estimates, such as the carrying value of goodwill and mortgage servicing rights and the fair value of investment securities (including whether any impairment on any investment security is temporary or other-than-temporary), involve judgments that are inherently forward-looking. There can be no assurance that future loan losses will be limited to the amounts estimated. Our ability to successfully implement new programs and initiatives, increase efficiencies and improve profitability is not entirely within our control and is not assured. The future effect of changes in the real estate markets and the Michigan and national 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. undertakes no obligation to update, amend or clarify forward-looking statements, whether as a result of new information, future events or otherwise.

Risk factors include, but are not limited to, the risk factors described in "Item 1A - Risk Factors" of Southern Michigan Bancorp, Inc.'s Annual Report on Form 10-K for the year ended December 31, 2008; the timing and level of asset growth; 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; and current uncertainties and fluctuations in the financial and credit 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.

SOUTHERN MICHIGAN BANCORP, INC.
NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

NOTE A - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation: The consolidated financial statements include the accounts of Southern Michigan Bancorp, Inc. (the Company) and its wholly-owned subsidiary, Southern Michigan Bank & Trust (SMB&T), after elimination of significant inter-company balances and transactions. FNB Financial was a wholly-owned subsidiary of the Company until its consolidation with SMB&T in April 2009. SMB&T owns SMB Mortgage Company, which transacts all residential real estate loans and it is consolidated into SMB&T's financial statements. SMB&T also owns FNB Financial Services, which conducts a brokerage business and is also consolidated into SMB&T's financial statements. During 2004, the Company formed a special purpose trust, Southern Michigan Bancorp Capital Trust I, for the sole purpose of issuing trust preferred securities. Under U.S. generally accepted accounting principles, the trust is not consolidated into the financial statements of the Company.

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions for Form 10-Q and Rule 8-03 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of management, all adjustments considered necessary in order to make the financial statements not misleading have been included. Operating results for the six months ended June 30, 2009 are not necessarily indicative of the results that may be expected for the year ending December 31, 2009.

The accompanying consolidated financial statements should be read in conjunction with the consolidated financial statements and footnotes of the Company for December 31, 2008 included in the Company's Annual Report on Form 10-K for the year ended December 31, 2008, filed with the Securities and Exchange Commission on March 30, 2009.

Reclassifications
Some items in the prior period consolidated financial statements have been reclassified to conform to the current year presentation.

NOTE B - NEW ACCOUNTING PRONOUNCEMENTS

Adoption of New Accounting Standards:

In April 2009, the FASB issued Staff Position (FSP) No. 115-2 and No. 124-2, Recognition and Presentation of Other-Than-Temporary Impairments,which amends existing guidance for determining whether impairment is other-than-temporary (OTTI) for debt securities. The FSP requires an entity to assess whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. If either of these criteria is met, the entire difference between amortized cost and fair value is recognized in earnings. For securities that do not meet the aforementioned criteria, the amount of impairment recognized in earnings is limited to the amount related to credit losses, while impairment related to other factors is recognized in other comprehensive income. Additionally, the FSP expands and increases the frequency of existing disclosures about other-than-temporary impairments for debt and equity securities. This FSP is effective for interim and annual reporting periods ending after June 15, 2009, with early adoption permitted for periods ending after March 15, 2009. The adoption of this FSP on April 1, 2009 did not have a material impact on the results of operations or financial position of the Company because the Company did not hold any other-than-temporary impaired debt securities.

In April 2009, the FASB issued Staff Position (FSP) No. 157-4, Determining Fair Value When the Volume and Level of Activity for the Asset or Liability Have Significantly Decreased and Identifying Transactions That Are Not Orderly. This FSP emphasizes that even if there has been a significant decrease in the volume and level of activity, the objective of a fair value measurement remains the same. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants. The FSP provides a number of factors to consider when evaluating whether there has been a significant decrease in the volume and level of activity for an asset or liability in relation to normal market activity. In addition, when transactions or quoted prices are not considered orderly, adjustments to those prices based on the weight of available information may be needed to determine the appropriate fair value. The FSP also requires increased disclosures. This FSP is effective for interim and annual reporting periods ending after June 15,

2009, and shall be applied prospectively. The adoption of this FSP as of April 1, 2009 did not have a material impact on the results of operations or financial position of the Company.

In April 2009, the FASB issued FSP No. 107-1 and APB 28-1,Interim Disclosures about Fair Value of Financial Instruments. This FSP amends FASB Statement No. 107,Disclosures about Fair Value of Financial Instruments, to require disclosures about fair value of financial instruments for interim reporting periods of publicly traded companies that were previously only required in annual financial statements. This FSP is effective for interim reporting periods ending after June 15, 2009. The adoption of this FSP as of April 1, 2009 did not have a material impact on the results of operations or financial position of the Company as it only required disclosures which are included in Note F.

FAS No. 165, "Subsequent Events," establishes general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued or are available to be issued. In particular, this Statement sets forth the period after the balance sheet date during which management of a reporting entity should evaluate events or transactions that may occur for potential recognition or disclosure in the financial statements, the circumstances under which an entity should recognize events or transactions occurring after the balance sheet date in its financial statements, and the disclosures that an entity should make about events or transactions that occurred after the balance sheet date. In accordance with this Statement, an entity should apply the requirements to interim or annual financial periods ending after June 15, 2009. The adoption of this Statement did not significantly change the financial statements. See Note H for additional comments.

Effect of Newly Issued But Not Yet Effective Accounting Standards:

FAS No. 166, "Accounting for Transfers of Financial Assets-an amendment of FASB Statement No. 140," removes the concept of a qualifying special-purpose entity from Statement 140 and removes the exception from applying FASB Interpretation No. 46 (revised December 2003), Consolidation of Variable Interest Entities, to qualifying special-purpose entities. The objective in issuing this Statement is to improve the relevance, representational faithfulness, and comparability of the information that a reporting entity provides in its financial statements about a transfer of financial assets; the effects of a transfer on its financial position, financial performance, and cash flows; and a transferor's continuing involvement, if any, in transferred financial assets. This Statement must be applied as of the beginning of each reporting entity's first annual reporting period that begins after November 15, 2009, for interim periods within that first annual reporting period and for interim and annual reporting periods thereafter. The impact of adoption is not expected to be material.

FAS No. 167, "Amendments to FASB Interpretation No. 46(R)," seeks to improve financial reporting by enterprises involved with variable interest entities. The statement addresses (1) the effects on certain provisions of FASB Interpretation No. 46 (revised December 2003), Consolidation of Variable Interest Entities, as a result of the elimination of the qualifying special-purpose entity concept in FASB Statement No. 166, Accounting for Transfers of Financial Assets, and (2) constituent concerns about the application of certain key provisions of Interpretation 46(R), including those in which the accounting and disclosures under the Interpretation do not always provide timely and useful information about an enterprise's involvement in a variable interest entity. This Statement is effective as of the beginning of each reporting entity's first annual reporting period that begins after November 15, 2009, for interim periods within that first annual reporting period, and for interim and annual reporting periods thereafter. The impact of adoption is not expected to be material.

FAS No. 168, "The FASB Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting Principles-a replacement of FASB Statement No. 162," will become the source of authoritative U.S. generally accepted accounting principles (GAAP) recognized by the FASB to be applied by nongovernmental entities. Rules and interpretive releases of the Securities and Exchange Commission (SEC) under authority of federal securities laws are also sources of authoritative GAAP for SEC registrants. On the effective date of this Statement, the Codification will supersede all then-existing non-SEC accounting and reporting standards. All other nongrandfathered non-SEC accounting literature not included in the Codification will become nonauthoritative. This Statement is effective for financial statements issued for interim and annual periods ending after September 15, 2009. The impact of adoption is not expected to be material.

NOTE C - EARNINGS PER SHARE

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

A reconciliation of the numerators and denominators of basic and diluted earnings per share for the three and six month periods ended June 30, 2009 and 2008 is as follows (dollars in thousands, except per share data):

The Company has performed an evaluation of its investments for other than temporary impairment. No impairment was identified. Unrealized gains and losses within the investment portfolio are determined to be temporary as the issuers are believed to be of high credit quality, management does not intend to sell the securities and the decline in fair value is largely due to changes in market interest rates. The fair value is expected to recover as the bonds approach their maturity date.

NOTE F - FAIR VALUE INFORMATION

The following methods and assumptions were used by the Company in estimating fair values for financial instruments:

Cash and cash equivalents and federal funds sold: The carrying amount reported in the balance sheet approximates fair value.

Securities available for sale: Fair values for securities available for sale are based on quoted market prices, where available.  For all other securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information, and the bond's terms and conditions, among other things.

---



Loans and loans held for sale, net: For variable-rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values. The fair values for other loans are estimated using discounted cash flows analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. The allowance for loan losses is considered to be a reasonable estimate of discount for credit quality concerns.

Accrued interest receivable: The carrying amount reported in the balance sheet approximates fair value.

Off-balance-sheet financial instruments: The estimated fair value of off-balance-sheet financial instruments is based on current fees or costs that would be charged to enter or terminate the arrangements. The estimated fair value is not considered to be significant for this presentation.

Deposits: The fair values disclosed for demand deposits (e.g., interest and non-interest checking, passbook savings, and certain types of money market accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amounts). Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of expected monthly maturities on time deposits.

Securities sold under agreements to repurchase, federal funds sold and purchased:The carrying amount reported in the balance sheet approximates fair value.

Other borrowings: The fair value of other borrowings is estimated using discounted cash flows analysis based on the current incremental borrowing rate for similar types of borrowing arrangements.

Subordinated debentures:The carrying amount reported in the balance sheet approximates fair value of the variable-rate subordinated debentures.

Accrued interest payable:The carrying amount reported in the balance sheet approximates fair value.

While these estimates of fair value are based on management's judgment of appropriate factors, there is no assurance that if the Company had disposed of such items at June 30, 2009 or December 31, 2008, respectively, the estimated fair values would have been achieved. Market values may differ depending on various circumstances not taken into consideration in this methodology. The estimated fair values at June 30, 2009 and December 31, 2008, respectively, should not necessarily be considered to apply at subsequent dates.

In addition, other assets and liabilities that are not defined as financial instruments are not included in the following disclosures, such as property and equipment. Also, non-financial instruments typically not recognized in financial statements may have value but are not included in the following disclosures.

The preceding table does not include net cash surrender value of life insurance and dividends payable which are also considered financial instruments. The estimated fair value of such items is considered to be their carrying amount.

The Company has also unrecognized financial instruments which relate to commitments to extend credit and standby letters of credit. The contract amount of such instruments is considered to be the fair value.

NOTE G - FAIR VALUE MEASUREMENTS

As of January 1, 2008, the Company adopted Financial Accounting Standards No. 157, Fair Value Measurements(FAS 157). In accordance with Financial Accounting Standards Board Staff Position (FSP) No. 157-2, Effective Date of FASB Statement No. 157, the Company adopted, as of January 1, 2009, the application of SFAS 157 for most nonfinancial assets and nonfinancial liabilities not recognized or disclosed at least annually at fair value. Items affected by this deferral included repossessions and other real estate, all for which any necessary impairment analyses are performed using fair value measures.

SFAS 157 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. The price in the principal (or most advantageous) market used to measure the fair value of the asset or liability shall not be adjusted for transaction costs. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets and liabilities; it is not a forced transaction. Market participants are buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact, and (iv) willing to transact.

SFAS 157 requires the use of valuation techniques that are consistent with the market approach, the income approach, and/or the cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities. The income approach uses valuation techniques to convert future amounts, such as cash flows or earnings, to a single present amount on a discounted basis. The cost approach is based on the amount that currently would be required to replace the service capacity of an asset (replacement cost). Valuation techniques should be consistently applied. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable, meaning those that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources, or unobservable, meaning those that reflect the reporting entity's own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. In that regard, SFAS 157 establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

Level 1 Inputs - Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Level 2 Inputs - Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.), or inputs that are derived principally from or corroborated by market data by correlation or other means.

Level 3 Inputs - Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity's own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.

A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, follows. These valuation methodologies were applied to all of the Company's financial and nonfinancial assets and liabilities carried at fair value.

---



In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon internally developed models that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality, the company's creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. The Company's valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While management believes the Company's valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date.

Securities Available for Sale. Securities classified as available for sale are reported at fair value utilizing Level 1, Level 2 and Level 3 inputs. Unadjusted quoted prices in active markets for identical assets are utilized to determine fair value at the measurement date for Level 1 securities.  For all other securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information, and the bond's terms and conditions, among other things. When there are unobservable inputs, such securities are classified as Level 3.

Impaired Loans. The Company does not record impaired loans at fair value on a recurring basis. However, periodically, a loan is considered impaired and is reported at the fair value of the underlying collateral, less estimated costs to sell, if repayment is expected solely from the collateral. Impaired loans measured at fair value typically consist of loans on nonaccrual status and loans with a portion of the allowance for loan losses allocated specific to the loan. Some loans may be included in both categories whereas other loans may only be included in one category. Collateral values are estimated using level 2 inputs, including recent appraisals, and Level 3 inputs based on customized discounting criteria.  Due to the significance of the level 3 inputs, impaired loans have been classified as level 3.

Other Real Estate Owned (OREO). The Company values OREO at the fair value of the underlying collateral less expected selling costs. Collateral values are estimated primarily using appraisals and reflect a market value approach.

Management evaluated subsequent events through August 14, 2009, the date the financial statements were issued. Events or transactions occurring after June 30, 2009, but prior to August 14, 2009, that provided additional evidence about conditions that existed at June 30, 2009, have been recognized in the financial statements for the six months ended June 30, 2009. Events or transactions that provided evidence about conditions that did not exist at June 30, 2009, but arose before the financial statements were issued, have not been recognized in the financial statements for the six months ended June 30, 2009.

|Item 2. | Management's Discussion and Analysis of Financial Condition and Results of Operations
|------- | -------------------------------------------------------------------------------------

The following discussion provides information about the financial condition and results of operations of the Company and its subsidiary bank, Southern Michigan Bank & Trust (SMB&T), for the three and six month periods ending June 30, 2009 and 2008. At the close of business on April 24, 2009, SMB&T and FNB Financial united under a single charter and single name: Southern Michigan Bank & Trust.

The continuing decline in economic conditions had a direct negative impact on the Company. High unemployment, reduced business activity and falling home prices have adversely affected the credit quality of the Company's loan portfolio. The continued decline in collateral values and cash flows for the Company's commercial and retail borrowers has resulted in higher delinquency rates, increased foreclosure activity and higher charge offs.

Results of Operations

For the first six months of 2009, Southern recorded net income of $480,000 and basic and diluted earnings per share of $0.21, compared with net income of $1,550,000 and basic and diluted earnings per share of $0.68 for the first six months of 2008. An $800,000 increase in the provision for loan losses as compared to the same period last year, a reduced net interest margin and costs of FDIC insurance, including a second quarter $217,000 special assessment, were the primary reasons for the decrease in net income.

Net income for the second quarter of 2009 was $751,000 compared to $349,000 for the same period of 2008. Basic and diluted earnings per share increased from $0.16 for the second quarter of 2008 to $0.33 for the same period of 2009. For the second quarter of 2009, the Company's provision for loan losses was $300,000 lower and non-interest income was $622,000 higher than the comparable period of 2008. The Company recorded $407,000 of gains on the sale of securities and $236,000 on the sale of loans during the second quarter of 2009 compared to $2,000 and $96,000, respectively, for the 2008 comparable period. A reduced net interest margin and

---

increased FDIC premiums, including a $217,000 special assessment for the second quarter of 2009, partially offset the increases.

Return on average assets was 0.21% for the first six months of 2009 compared to 0.64% for the first six months of 2008. Return on average shareholders' equity was 2.13% for the first six months of 2009 compared to 6.75% for the same period in 2008.

Net Interest Income

The Company derives the greatest portion of its income from net interest income. During 2008, the Federal Open Market Committee lowered short-term rates eight times for a total of 400 basis points. The Company has been able to lower its cost of funds by 84 basis points compared to June 30, 2008, but tax equivalent yields on average assets declined to 5.48% from 6.53% for the same periods. This resulted in a decline in the interest rate spread and net interest margin.

The following tables provide information regarding interest income and expense for the six-month periods ended June 30, 2009 and 2008, respectively. Table 1 shows the year-to-date daily average balances for interest earning assets and interest bearing liabilities, interest earned or paid, and the annualized effective rate, for the six-month periods ended June 30, 2009 and 2008. Table 2 shows the effect on interest income and expense of changes in volume and interest rates on a tax equivalent basis.

As shown in Tables 1 and 2, tax equivalent net interest income decreased $870,000, or 9.3%, in the first six months of 2009 compared to the same period in 2008. Net interest income decreased $688,000 during the first six months of 2009 compared to the first six months of 2008 on a tax equivalent basis. This decrease was due primarily to the rate decreases described above.

The presentation of net interest income on a tax equivalent basis is not in accordance with U.S. generally accepted accounting principles ("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 net interest income on a tax equivalent basis were $291,000 and $320,000 for the six months ended June 31, 2009 and 2008, respectively. These adjustments were computed using a 34% federal income tax rate.

Provision for Loan Losses

The provision for loan losses is based on an analysis of the required additions to the allowance for loan losses. The provision is charged to income to bring the allowance for loan losses to a level believed appropriate by management. The allowance for loan losses is maintained at a level believed adequate by management to absorb probable incurred losses in the loan portfolio. Some factors considered by management in determining the level at which the allowance is maintained include specific credit reviews, historical loan loss experience, current economic conditions and trends, results of examinations by regulatory agencies and the volume, growth and composition of the loan portfolio. The provision is adjusted quarterly, if necessary, to reflect changes in the factors above, as well as actual charge-off experience and any known losses.

The provision for loan losses was $500,000 for the second quarter of 2009, down from $1,450,000 for the first quarter of 2009 and $800,000 for the second quarter of 2008. However, for the first six months of 2009 the provision totaled $1,950,000 compared to $1,150,000 for the same period of 2008. Ongoing economic issues have

resulted in stresses on borrowers resulting in the increase in the 2009 provision for loan losses. While specific reserves have decreased at June 30, 2009 from December 31, 2008 levels, it was a result of a number of loans with specific reserves being charged off. Net charge-offs increased significantly in the first quarter of 2009 to $1,664,000 compared to $197,000 for the first quarter of 2008, but then declined by over fifty percent to $766,000, for the second quarter of 2009. Net charge-offs are projected to decline further in the third and fourth quarters.

The allowance was 1.99% of total loans at June 30, 2009 compared to 2.12% at December 31, 2008.

Charge-offs and recoveries for respective loan categories for the six months ended June 30, 2009 and 2008 were as follows:

(Dollars in Thousands)

|                        | 2009        |       | 2008      
|----------------------- | ----------- | ----- | ----------
|                        | Charge-offs |       | Recoveries
|                        |             |       |           
|Commercial              | $           | 1,556 |           
|Residential real estate |             | 795   |           
|Consumer                |             | 179   |           
|Total                   | $           | 2,530 |           

Net charge-offs in the first six months of 2009 were $2,430,000, or 1.46%, of average loans on an annualized basis. Net charge-offs in the first six months of 2008 were $698,000, or 0.41%, of average loans on an annualized basis.

Non-interest income

Second quarter total non-interest income increased from $1,516,000 at June 30, 2008 to $2,138,000 at June 30, 2009, an increase of $622,000. Year to date total non-interest income increased from $3,466,000 at June 30, 2008 to $3,626,000 at June 30, 2009, an increase of $160,000.

The Company sold $15.5 million of securities and recorded $407,000 in gains on security sales during the second quarter of 2009, as the Company reduced the level of mortgage backed securities it held.

Fixed rate long term residential mortgages are generally sold in the secondary market, while adjustable rate mortgages are retained in the loan portfolio. Income for loans sold in the secondary market increased $140,000, or 145.8%, in the second quarter of 2009 compared to the second quarter of 2008, and through the first six months of 2009 was $215,000, or 100%, above the levels for the same period in 2008. This improvement is a result of recent rate driven refinancing activity.

Trust fees were down 12.3%, or $32,000, for the second quarter of 2009 compared to the second quarter of 2008, and through six months of 2009 were down 12.6%, or $69,000, compared to the same period of 2008. This decline in income reflects a decline in market value of assets managed despite an increase in new accounts.

Service charges on deposit accounts decreased 3.3%, or $45,000, during the first six months of 2009 compared to 2008. However service charges on deposit accounts were up 6.8%, or $47,000, in the second quarter of 2009 compared to the second quarter of 2008, as service charges were standardized when the two banks were consolidated in April, 2009.

Non-interest expense

Total non-interest expense decreased $49,000, or 0.5%, comparing the six month periods ending June 30, 2009 and 2008. Total non-interest expense increased $99,000, or 2.1%, for the second quarter of 2009 compared to the second quarter of 2008.

---



Salaries and employee benefits decreased $143,000 or 5.6%, during the second quarter of 2009 when compared to the same period in 2008 and $320,000, or 6.1%, for the first six months of 2009 compared to the same period in 2008. The Company has been able to reduce staff through attrition and has reduced contributions to the 401(k) plan. At June 30, 2009, the Company had 198 full time equivalent positions (FTE) compared to 203 at June 30, 2008.

Occupancy costs decreased for both the three and six month periods ending June 30, 2009 compared to the same periods in 2008. The Company incurred reduced building repair and maintenance costs in the first six months of 2009 compared to the same period in 2008.

Equipment and software maintenance costs were lower for the both the three and six month periods ending June 30, 2009 compared to the same periods of 2008. Depreciation expense has declined in 2009 compared to 2008 for both the three and six month periods ending June 30.

Professional and outside services decreased during both the three and six month periods ending June 30, 2009 compared to the same periods in 2008. The core system conversion was completed during the second quarter of 2008 increasing the outside services fee expense.

The Company's FDIC insurance expense increased $394,000, or 3,030.8%, in the second quarter of 2009 and $480,000, or 1,230.8%, in the first six months of 2009 over the same period in 2008, as a result of increased premiums, a special assessment and the elimination of credits at the end of 2008. Included in the second quarter of 2009 was $217,000 for a FDIC special assessment.

Other non-interest expense increased for both the second quarter and year to date period ending June 30, 2009. Expenses related to OREO property, including costs to maintain the property, write-downs of the value and losses on the sale of the property increased $217,000 for the six months ending June 30, 2009 compared to the same period in 2008. The Company is carrying 32 properties as of June 30, 2009 compared to 14 at June 30, 2008.

Federal income taxes

Income taxes were a credit of $205,000 for the first six months of 2009 compared to an expense of $157,000 for the comparable period in 2008. Because of the decline in 2009 income before taxes, a federal income tax credit resulted after consideration of tax-exempt interest income and other normal tax reconciling items. Tax-exempt income continues to have a major impact on the Company's tax provision or credit. The benefit offsetting lower coupon rates on municipal instruments is the nontaxable feature of the income earned on such investments. This resulted in a lower effective tax rate and a reduced federal income tax provision or credit.

Financial Condition

Assets

Total assets decreased $18.5 million at June 30, 2009 compared to December 31, 2008. Cash and cash equivalents decreased $10.1 million and investments decreased $5.3 million at June 30, 2009 compared to December 31, 2008, due to $14.2 million of non core deposits being eliminated from the balance sheet in the first quarter of 2009.

Gross loans decreased $2,856,000, or 0.9%, as of June 30, 2009 compared to December 31, 2008. The Company is controlling growth during these difficult economic times. The decrease resulted from net charge offs and payments received on loans exceeding the new loan volume.

Nonperforming assets

Nonperforming assets include nonaccrual loans, accruing loans past due 90 days or more, and other real estate owned, which includes real estate acquired through foreclosure and deeds in lieu of foreclosure.

---



A loan generally is classified as nonaccrual when full collectibility of principal or interest is doubtful or a loan becomes 90 days past due as to principal or interest, unless management determines that the estimated net realizable value of the collateral is sufficient to cover the principal balance and accrued interest. When interest accruals are discontinued, unpaid interest is reversed. Nonperforming loans are returned to performing status when the loan is brought current and has performed in accordance with contract terms for a period of time.

The following table sets forth the aggregate amount of nonperforming assets in each of the following categories:

(Dollars in thousands)

|                                        |         |       |          |   |         |  
|Total nonperforming loans               |         | 7,357 |          |   | 9,152   |  
|Other real estate owned                 |         | 1,761 |          |   | 1,119   |  
|                                        |         |       |          |   |         |  
|Total nonperforming assets              | $       | 9,118 |          | $ | 10,271  |  
|Nonperforming loans to total loans      |         | 2.21  | %        |   | 2.73    | %
|Nonperforming assets to total assets    |         | 2.00  | %        |   | 2.16    | %

Nonperforming loans are subject to continuous monitoring by management and estimated losses are specifically allocated for in the allowance for loan losses where appropriate.

Holdings of other real estate owned at June 30, 2009 increased by $642,000 since the end of 2008. Other real estate owned includes properties that were acquired through foreclosure or in lieu of foreclosure. The properties include residential homes and lots as well as commercial properties. The increase in other real estate owned reflects the increased level of foreclosure activity.

In management's evaluation of the loan portfolio risks, any significant future increases in nonperforming loans is dependent to a large extent on the economic environment. In a deteriorating or uncertain economy, such as the current environment, management applies more conservative assumptions when assessing the future prospects of borrowers and when estimating collateral values. This has resulted in a higher number of loans being classified as nonperforming.

Liabilities

Deposits decreased $18.2 million from December 31, 2008 to June 30, 2009. The decrease consisted of primarily one non core deposit relationship, totaling $14.2 million, which was eliminated during the first quarter of 2009. The majority of deposits are derived from core client sources, relating to long term relationships with local personnel, business and public clients. A small amount of brokered deposits are maintained, but are not used to support growth.

Shareholders' equity

As of June 30, 2009, total shareholders' equity increased $221,000 from December 31, 2008. The increase is primarily attributable to the current year's net income offset by dividends to shareholders.

The following table summarizes the Company's regulatory capital ratios as of June 30, 2009 and December 31, 2008:

|                               | June 30, 2009 |   | December 31, 2008 |      | Minimum Required for

|Tier I capital ratio           | 10.3          | % |                   | 9.7  | %                                             
|Leverage ratio                 | 7.7           | % |                   | 7.9  | %                                             

Liquidity

Liquidity management involves the ability of the Company to meet the cash flow requirements of customers who may be either depositors wanting to withdraw funds or borrowers needing assurance that sufficient funds will be available to meet their credit needs. SMB&T maintains certain levels of liquid assets (the most liquid of which are cash and cash equivalents, federal funds sold and investment securities) in order to meet these demands. Maturing loans and investment securities are the principal sources of asset liquidity. Liquidity is monitored and closely managed by the Asset/Liability Management Committee (ALCO), whose members are comprised of senior management.

In the past, the Company has used overnight federal funds lines of credit with correspondent banks as a short term source of liquidity. The recent events within the financial industry have caused correspondent banks to eliminate these lines of credit that were previously available to the Company. As a result, to ensure adequate liquidity, collateral is pledged at the Federal Reserve Discount Window. At June 30, 2009, $2.1 million of securities were pledged that could be used for future borrowings. In addition, the Company has $12.6 million of securities which are available to be pledged for future borrowings. The Company also has the ability to borrow $36.5 million from the Federal Home Loan Bank based on FHLB stock owned and collateral pledged.

The Company's principal source of funds to pay cash dividends is the dividends paid by SMB&T.

Impact of Inflation and Changing Prices

The majority of assets and liabilities of a financial institution are monetary in nature and differ greatly from most commercial and industrial companies that have significant investments in fixed assets or inventories. However, inflation does have an important impact on the growth of total assets in the banking industry and the resulting need to increase equity capital at higher than normal rates in order to maintain an appropriate equity-to-assets ratio. Another significant effect of inflation is on other expenses, which tend to rise during periods of general inflation.

|Item 4T. | Controls and Procedures
|-------- | -----------------------

An evaluation was performed under the supervision and with the participation of the Company's management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Company's disclosure controls and procedures (as defined in Rule 15d - 15(e) under the Exchange Act) as of June 30, 2009. Based on and as of the time of that evaluation, the Company's management, including the Chief Executive Officer and Chief Financial Officer, concluded that as of the end of the period covered by this report the Company's disclosure controls and procedures were 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 the Securities and Exchange Commission's rules and forms.

There was no change in the Company's internal control over financial reporting that occurred during the three months ended June 30, 2009 that has materially affected, or that is reasonably likely to materially affect, the Company's internal control over financial reporting.
