NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 — BASIS OF PRESENTATION

The consolidated financial statements of Middlefield Banc Corp. (“Middlefield”) includes its wholly owned subsidiary, The Middlefield Banking Company (the “Bank”). All significant inter-company items have been eliminated.

The accompanying financial statements have been prepared in accordance with U.S. generally accepted accounting principles and the instructions for Form 10-Q and Article 10 of Regulation S-X. In Management’s opinion, the financial statements include all adjustments, consisting of normal recurring adjustments, that Middlefield considers necessary to fairly state Middlefield’s financial position and the results of operations and cash flows. The balance sheet at December 31, 2006, has been derived from the audited financial statements at that date but does not include all of the necessary informational disclosures and footnotes as required by U. S. generally accepted accounting principles. The accompanying financial statements should be read in conjunction with the financial statements and notes thereto included with Middlefield’s Form 10-K (File No. 33-23094). The results of Middlefield’s operations for any interim period are not necessarily indicative of the results of Middlefield’s operations for any other interim period or for a full fiscal year.

Recent Accounting Pronouncements

In September 2006, the FASB issued FAS No. 157, Fair Value Measurements, which provides enhanced guidance for using fair value to measure assets and liabilities. The standard applies whenever other standards require or permit assets or liabilities to be measured at fair value. The Standard does not expand the use of fair value in any new circumstances. FAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. Early adoption is permitted. The adoption of this standard is not expected to have a material effect on the Company’s results of operations or financial position. Or The Company is currently evaluating the impact the adoption of the standard will have on the Company’s results of operations.

In February 2007, the FASB issued FAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities – Including an amendment of FASB Statement No. 115, which provides all entities with an option to report selected financial assets and liabilities at fair value. The objective of the FAS No. 159 is to improve financial reporting by providing entities with the opportunity to mitigate volatility in earnings caused by measuring related assets and liabilities differently without having to apply the complex provisions of hedge accounting. FAS No. 159 is effective as of the beginning of an entity’s first fiscal year beginning after November 15, 2007. Early adoption is permitted as of the beginning of a fiscal year that begins on or before November 15, 2007 provided the entity also elects to apply the provisions of FAS No. 157, Fair Value Measurements. The adoption of this standard is not expected to have a material effect on the Company’s results of operations or financial position.

In June 2006, the FASB issued FASB Interpretation No. 48 (“FIN 48”), Accounting for Uncertainty in Income Taxes. FIN 48 is an interpretation of FAS No. 109, Accounting for Income Taxes, and it seeks to reduce the diversity in practice associated with certain aspects of measurement and recognition in accounting for income taxes. In addition, FIN No. 48 requires expanded disclosure with respect to the uncertainty in income taxes and is effective for fiscal years beginning after December 15, 2006. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s results of operations.

In September 2006, the FASB reached consensus on the guidance provided by Emerging Issues Task Force Issue 06-4 (“EITF 06-4”), Accounting for Deferred Compensation and Postretirement Benefit Aspects of Endorsement Split-Dollar Life Insurance Arrangements. The guidance is applicable to endorsement split-dollar life insurance arrangements, whereby the employer owns and controls the insurance policy, that are associated with a postretirement benefit. EITF 06-4 requires that for a split-dollar life insurance arrangement within the scope of the Issue, an employer should recognize a liability for future benefits in accordance with FAS No. 106 (if, in substance, a postretirement benefit plan exists) or Accounting Principles Board Opinion No. 12 (if the arrangement is, in substance, an individual deferred compensation contract) based on the substantive agreement with the employee. EITF 06-4 is effective for fiscal years beginning after December 15, 2007. The Company is currently evaluating the impact the adoption of the EITF will have on the Company’s results of operations or financial condition.

In March 2007, the FASB ratified Emerging Issues Task Force Issue No. 06-10 (“EITF 06-10”), Accounting for Collateral Assignment Split-Dollar Life Insurance Agreements. EITF 06-10 provides guidance for determining a liability for the postretirement benefit obligation as well as recognition and measurement of the associated asset on the basis of the terms of the collateral assignment agreement. EITF 06-10 is effective for fiscal years beginning after December 15, 2007. The Company is currently evaluating the impact the adoption of the EITF will have on the Company’s results of operations or financial condition.

In June 2007, the FASB ratified Emerging Issues Task Force Issue No. 06-11 (“EITF 06-11”), Accounting for Income Tax Benefits of Dividends on Share-Based Payment Awards. EITF 06-11 applies to share-based payment arrangements with dividend protection features that entitle employees to receive (a) dividends on equity-classified nonvested shares, (b) dividend equivalents on equity-classified nonvested share units, or (c) payments equal to the dividends paid on the underlying shares while an equity-classified share option is outstanding, when those dividends or dividend equivalents are charged to retained earnings under FAS No. 123R, Share-Based Payment, and result in an income tax deduction for the employer. A consensus was reached that a realized income tax benefit from dividends or dividend equivalents that are charged to retained earnings and are paid to employees for equity-classified non-vested equity shares, non-vested equity share units, and outstanding equity share options should be recognized as an increase in additional paid-in capital. EITF 06-11 is effective for fiscal years beginning after December 15, 2007, and interim periods within those fiscal years. The Company is currently evaluating the impact the adoption of the EITF will have on the Company’s financial condition.

NOTE 2 — STOCK-BASED COMPENSATION

The Company adopted FAS 123R on January 1, 2006 and applied the modified prospective transition method. Under this transition method, the Company (1) did not restate any prior periods and (2) are recognizing compensation expense for all share-based payment awards that were outstanding, but not yet vested, as of January 1, 2006, based upon the same estimated grant-date fair values and service periods used to prepare the FAS 123 pro-forma disclosures.

During the six months ended June 30, 2007, the Company recorded no compensation as no options vested during the year. As of June 30, 2007, there was approximately $26,435 of unrecognized compensation cost related to the unvested share-based compensation awards granted. That cost is expected to be recognized in 2007.

FAS 123R requires that the cash flows from the tax benefits resulting from tax deductions in excess of the compensation cost recognized for stock-based awards (excess tax benefits) be classified as financing cash flows. Prior to the adoption of FAS 123R, such excess tax benefits were presented as operating cash flows. Accordingly, there have been no excess tax benefits that have been classified as a financing cash inflow for the six months ended June 30, 2007 in the Consolidated Statements of Cash Flows.

Prior to adopting FAS 123R, the Company accounted for share-based payment awards using the intrinsic value method of APB 25 and related interpretations. Under APB 25, the Company did not record compensation expense for employee share options, unless the awards were modified, because the share options were granted with exercise prices equal to or greater than the fair value of our stock on the date of grant. The Company did not have any non-vested stock options outstanding during the periods ended June 30, 2006. There were no options issued during the three and six months ended June 30, 2006.

Stock option activity during the six months ended June 30, 2007 and 2006 is as follows:

						Weighted-								Weighted-
						average								average
						Exercise								Exercise
		2007				Price				2006				Price

Forfeited			—				—				—				—
Outstanding, June 30			82,933			$	28.99				75,617			$	26.87

NOTE 3 — EARNINGS PER SHARE

Middlefield provides dual presentation of Basic and Diluted earnings per share. Basic earnings per share utilizes net income as reported as the numerator and the actual average shares outstanding as the denominator. Diluted earnings per share includes any dilutive effects of options, warrants, and convertible securities.

There are no convertible securities that would affect the numerator in calculating basic and diluted earnings per share; therefore, net income as presented on the Consolidated Statement of Income (Unaudited) will be used as the numerator. The following tables set forth the composition of the weighted-average common shares (denominator) used in the basic and diluted earnings per share computation.

		For the Three								For the Six
		Months Ended								Months Ended
		June 30,								June 30,

Weighted average common shares and common stock equivalents used to calculate basic earnings per share			1,503,412				1,418,496				1,464,975				1,420,620
Additional common stock equivalents (stock options) used to calculate diluted earnings per share			20,441				23,365				20,932				22,953
Weighted average common shares and common stock equivalents used to calculate diluted earnings per share			1,523,853				1,441,861				1,485,907				1,443,573

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis provides further detail to the financial condition and results of operations of the Company. The MD&A should be read in conjunction with the notes and financial statements presented in this report.

CHANGES IN FINANCIAL CONDITION

General. The Company’s total assets increased by $65.6 million or 19.2% from December 31, 2006 to June 30, 2007 to a balance of $406.4 million. On April 19, 2007 Middlefield Banc Corp. completed the acquisition of Emerald Bank, an Ohio-chartered savings bank headquartered in Dublin, Ohio. Emerald Bank will operate as a separate banking subsidiary of Middlefield under the Emerald Bank name, employing a commercial bank charter. The acquisition of Emerald Bank represented $42.6 million or 62.7% of the asset growth for the first six months of 2007. Loans receivable and investment securities increased $53.3 million and $8.8 million respectively. The increase in total assets reflects a corresponding increase in total liabilities of $61.5 million or 19.8% and an increase in stockholders’ equity of $4.0 million or 13.2%. The increase in total liabilities was primarily the result of growth in deposits of $55.8 million, $37.4 of which were the result of the purchase of Emerald Bank. The increase in stockholders’ equity was the result of increases in common stock and retained earnings of $4.0 million and $1.0 million, respectively, as well as decreases in comprehensive loss and treasury stock of $768,000 and $197,000 respectively.

Cash on hand and due from banks. Cash on hand and due from banks represent cash equivalents. Cash equivalents declined a combined $1.2

million or 8.7% to $12.5 million at June 30, 2007 from $13.6 million at December 31, 2006. Deposits from customers into savings and checking accounts, loan and security repayments and proceeds from borrowed funds typically increase these accounts. Decreases result from customer withdrawals, new loan originations, security purchases and repayments of borrowed funds. The decline for the first six months can principally be attributed a decrease in Federal Funds Sold which was used to fund the loan portfolio.

Investment securities. Investment securities available for sale ended the June 30, 2007 quarter at $71.9 million an increase of $8.8 million or 14.0% from $63.1 million at December 31, 2006. During this period the Company recorded purchases of available for sale securities of $12.6 million, consisting of purchases of municipal bonds. Offsetting the purchases of securities were repayments and maturities of securities of $2.5 million during the six months ended June 30, 2007. In addition, the securities portfolio decreased approximately $768,000 due to a decline in the market value. These fair value adjustments represent temporary fluctuations resulting from changes in market rates in relation to average yields in the available for sale portfolio. If securities are held to their respective maturity dates, no fair value gain or loss is realized.

Loans receivable. The loans receivable category consists primarily of single family mortgage loans used to purchase or refinance personal residences located within the Company’s market area and commercial real estate loans used to finance properties that are used in the borrowers businesses or to finance investor-owned rental properties, and to a lesser extent commercial and consumer loans. Net loans receivable increased $52.9 million or 21.5% to $299.2 million at June 30, 2007 from $246.3 million at December 31, 2006. Included in this increase were increases in mortgage loans of $32.1 million or 22.9% and commercial loans of $15.3 million or 19.6%, as well as an increase in home equity loans of $5.5 million during the six months ended June 30, 2007. The Corporation’s lending philosophy is to focus on the commercial loans and to attempt to grow the portfolio. To attract and build the commercial loan portfolio, the Corporation has taken a proactive approach in contacting new and current clients to ensure that the Corporation is servicing its client’s needs. These lending relationships generally offer more attractive returns than residential loans and also offer opportunities for attracting larger balance deposit relationships. However, the shift in loan portfolio mix from residential real estate to commercial oriented loans may increase credit risk.

Non-performing loans. Non-performing loans included non-accrual loans, renegotiated loans, loans 90 days or more past due, other real estate loans, and repossessed assets. A loan is classified, as non-accrual when, in the opinion of management, there are serious doubts about collectibility of interest and principal. At the time the accrual of interest is discontinued, future income is recognized only when cash is received. Renegotiated loans are those loans which terms have been renegotiated to provide a reduction or deferral of principal or interest as a result of the deterioration of the borrower. Non-performing loans amounted to $3.7 million or 1.21% and $1.3 million or 0.54% of total loans at June 30, 2007 and December 31, 2006, respectively. One commercial real estate credit, which was well secured and in the process of collection, accounted for $0.8 million of the increase. The majority of the remaining increase in this category was in residential secured real estate loans.

Deposits. The Company considers various sources when evaluating funding needs, including but not limited to deposits, which are a significant source of funds totaling $326.9 million or 88.4% of the Company’s total funding sources at June 30, 2007. Total deposits increased $55.8 million or 20.6% to $326.9 million at June 30, 2007 from $271.1 million at December 31, 2006. The increase in deposits is primarily related to the growth of certificates of deposits that totaled $171.8 million at June 30, 2007 an increase of $22.5 million or 15.0% for the year. Saving deposits and money market accounts increased $18.8 and $12.8 respectively, while interest-bearing demand increased $346,000, or .8%, during the six months ended June 30, 2007.

Borrowed funds. The Company utilizes short and long-term borrowings as another source of funding used for asset growth and liquidity needs. These borrowings primarily include FHLB advances, junior subordinated debt and repurchase agreements. Borrowed funds increased $5.3 million or 14.0% to $43.0 million at June 30, 2007 from $37.7 million at December 31, 2006. FHLB advances increased $1.1 million or 3.1% while Federal Funds purchased increased $3.7% or 100%. The increase in FHLB advances was the result of Emerald Bank’s FHLB borrowings which totaled $3.2 million which was practically offset with the runoff of $2.1 million of advances to the Middlefield bank.

Stockholders’ equity. Stockholders’ equity increased $4.0 million or 13.2% to $34.5 million at June 30, 2007 from $30.5 million at December 31, 2006. The increase in stockholders’ equity was the result of increases in common stock and retained earnings of $4.0 million and $1.0 million, respectively, as well as, decreases in accumulated other comprehensive loss and treasury stock of $768,000 and $197,000 respectively. The decrease of accumulated other comprehensive loss was the result of a reduction in the mark to market of the Company’s securities available for sale portfolio. The decline in treasury stock was the result of the purchase of 5,000 shares of the bank’s common stock at an average price of $39.35 since December 31, 2006.

RESULTS OF OPERATIONS

General. Net income for the second quarter of 2007 totaled $899,231, or 9.0 percent less than the $987,800 reported for the same period in 2006. Diluted earnings per share for the second quarter of 2007 were $0.59, a 14.5% decrease from 2006’s second quarter diluted earnings per share of $0.69. These second quarter results include the operations of Emerald Bank of Dublin, Ohio, which became a subsidiary of Middlefield on April 19, 2007.

Results from the first half of 2007 reflect a net income of $1,651,606; an 8.5% decrease compared to $1,805,372 for the first half of 2006. Diluted earnings per share for the first half of 2007 were $1.11, or 11.9% less than diluted earnings per share of $1.26 for the first six months of 2006. These figures include Emerald Bank’s operations from April 19, 2007 through June 30, 2007.

Net interest income. Net interest income, the primary source of revenue for the Company, is determined by the Company’s interest rate spread, which is defined as the difference between income on earning assets and the cost of funds supporting those assets, and the relative amounts of interest earning assets and interest bearing liabilities. Management periodically adjusts the mix of assets and liabilities, as well as the rates earned or paid on those assets and liabilities in order to manage and improve net interest income. The level of interest rates and changes in the amount and composition of interest earning assets and liabilities affect the Company’s net interest income. Historically from an interest rate risk perspective, it has been management’s perception that differing interest rate environments can cause sensitivity to the Company’s net interest income, these being extended low long-term interest rates or rapidly rising short-term interest rates.

Net interest income for the second quarter was $2.9 million, an increase of 4.5% from the $2.8 million reported for the comparable period of 2006. The net interest margin was 3.31% for the second quarter of 2007, down from the 3.88% reported for the same quarter of 2006. The decline is primarily attributable to higher deposit costs and competitive pricing on lending opportunities associated with the current interest rate environment. Deposit growth at the banks has primarily been in products such as time deposits and money market accounts, which generally carry higher interest costs than other deposit alternatives. The Middlefield subsidiary offered a special money market promotion during the first quarter of 2007, which was tied to the grand opening of the Newbury banking office. Emerald Bank found most of its deposit growth in its Prime Savings Account product, which is positioned at 300 basis points below the Prime Rate.

Net interest income increased $50,000, or .9%, for the six months ended June 30, 2007 compared to the same period in the prior year. This increase in net interest income can be attributed to an increase in interest income of $2.3 million, partially offset by an increase in interest expense of $2.2 million. The net interest margin was 3.36% for the first half of 2007, down from the 3.88% reported for the same period of 2006. The decline is primarily attributable to higher deposit costs and competitive pricing on lending opportunities associated with the current interest rate environment. Deposit growth at the banks has primarily been in products such as time deposits and money market accounts, which generally carry higher interest costs than other deposit alternatives. The Middlefield subsidiary offered a special money market promotion during the first quarter of 2007, which was tied to the grand opening of the Newbury banking office. Emerald Bank found most of its deposit growth in its Prime Savings Account product, which is positioned at 300 basis points below the Prime Rate.

Interest income. Interest income increased $1.5 million, or 30.2%, for the three months ended June 30, 2007, compared to the same period in the prior year. This increase can be attributed to growth in interest earned on loans receivable, investment securities and interest bearing deposits with other banks of $1.1 million, $177,000 and $173,000 respectively. Interest income increased $2.3 million, or 24.3%, for the six months ended June 30, 2007, compared to the same period in the prior year. This increase can be attributed to increases in interest earned on loans receivable, investment securities and interest bearing deposits with other banks of $1.6 million, $273,000 and $362,000 respectively.

Interest earned on loans receivable increased $1.1 million, or 26.0%, for the three months ended June 30, 2007, compared to the same period in the prior year. This increase was attributable to an increase in the average balance of loans outstanding of $50.9 million, or 21.4%, to $289.1 million for the three months ended June 30, 2007 compared to $238.2 million for the same period in the prior year. Loan interest income was enhanced by an increase in the yield on the loans to 7.37% for the three months ended June 30, 2007 from 7.1% for the same period in the prior year.

For the six months ended June 30, 2007, interest earned on loans receivable increased $1.6 million, or 16.3%, , compared to the same period in the prior year. This increase was attributable to an increase in the average balance of loans outstanding of $34.8 million, or 14.8%, to $270.8 million for the six months ended June 30, 2007 compared to $236.0 million for the same period in the prior year. Loan interest income was enhanced by an increase in the yield on the loans to 7.33% for the six months ended June 30, 2007 from 7.01% for the same period in the prior year.

Interest earned on securities increased $177,000, or 32.9%, for the three months ended June 30, 2007, compared to the same period in the prior year. This increase was primarily the result of an increase in the average balance of the securities portfolio of $15.4 million, or 27.1%, to $72.4 million at June 30, 2007 from $57.0 million for the same period in the prior year. Interest earned on securities was enhanced by an increase in the yield on the investments to 5.27% for the three months ended June 30, 2007 from 4.69% for the same period in the prior year.

Interest earned on securities increased $273,000, or 25.1%, for the six months ended June 30, 2007, compared to the same period in the prior year. This increase was primarily the result of an increase in the average balance of the securities portfolio of $11.3 million, or 19.6%, to $69.0 million at June 30, 2007 from $57.7 million for the same period in the prior year. Interest earned on securities was enhanced by an increase in the yield on the investments to 5.25% for the three months ended June 30, 2007 from 4.70% for the same period in the prior year.

Interest expense. Interest expense increased $1.3 million, or 64.9%, for the three months ended June 30, 2007, compared to the same period in

the prior year. This increase in interest expense can be attributed to increases in interest incurred on deposits and other borrowing $1.2 million and $172,000, respectively. For the six months ended June 30, 2007 interest expense increased $2.2 million, or 56.4% compared to the same period in the prior year. This increase in interest expense can be attributed to increases in interest incurred on deposits and other borrowing $2.0 million and $344,000, respectively.

Interest incurred on deposits, the largest component of the Company’s interest-bearing liabilities, increased $1.2 million , or 71.0%, for the three months ended June 30, 2007, compared to the same period in the prior year. This increase was primarily attributable to an increase in the cost of interest-bearing deposits to 4.14% from 3.15% for the quarters ended June 30, 2007 and 2006, respectively. Additionally the average balance of interest-bearing deposits increased by $64.1 million, or 30.0%, to $277.9 million for the three months ended June 30, 2007, compared to $213.8 million for the same period in the prior year. The Company diligently monitors the interest rates on its products as well as the rates being offered by its competition and utilizing rate surveys to keep its total interest expense costs down. For the six months ended June 30, 2007 interest incurred on deposits, increased $2.0 million, or 35.9%, compared to the same period in the prior year. This increase was primarily attributable to an increase in the cost of interest-bearing deposits to 4.04% for the six months ended June 30, 2007 compared to 3.05% for the same period in the prior year. In addition the increase in the cost of interest-bearing deposits was also attributed to an increase in the average balance of interest-bearing deposits of $46.1 million, or 21.6%, to $259.1 million for the six months ended June 30, 2007, compared to $213.0 million for the same period in the prior year.

Interest incurred on borrowed funds, increased $130,000, or 36.2%, for the three months ended June 30, 2007, compared the same period in the prior year. This increase was primarily attributable to the increase in the cost of these funds to 5.02% from 4.51% for the quarters ended June 30, 2007 and 2006, respectively. Adding to the cost of these funds was a rise in the average balance of borrowed funds of $7.2 million, or 22.4%, to $39.2 million for the three months ended June 30, 2007, compared to $32.0 million for the same period in the prior year. This increase is reflected in the quarterly rate volume report presented below which depicts that the increase to the costs associated with the interest-bearing liabilities.

For the six months ended June 30, 2007, interest incurred on borrowed funds increased $261,000, or 37.6%, compared to the same period in the prior year. This increase was attributable to the rise in the average balance of borrowed funds of $6.7 million, or 21.2%, to $38.2 million for the six months ended June 30, 2007, compared to $31.5 million for the six months ended June 30, 2006. Adding to the expense of these funds was a rise in the cost to 5.04% for the six months ended June 30, 2007, compared to 4.44% for the same period in the prior year.

Provision for loan losses. Provision for loan losses was $114,000 for the 2007 six month period, which was in line with the company’s plan. While lower than the $150,000 provision during the first six months of 2006, this amount was in keeping with the company’s intention to reduce the unallocated portion of its loan loss reserve. The provision is maintained at a level to absorb management’s estimate of probable inherent credit losses within the bank’s loan portfolio. At June 30, 2007, the allowance for loan losses as a percentage of total loans was 1.09%, which was down from the 1.23% reported at June 30, 2006. The ratio of non-performing loans to total loans stood at 1.16% at June 30, 2007. This was an increase from the 0.82% reported as of June 30, 2006. Loans classified as non-accrual at June 30, 2007, were $1.69 million, which was $0.1 million less than the total reported at June 30, 2006. Loans past due 90 days and still accruing interest, as of June 30, 2007, were $1.8 million, or $1.7 million more than the prior year figure. One commercial real estate credit, which was well secured and in the process of collection, accounted for $0.8 million of the increase. The majority of the remaining increase in this category was in residential secured real estate loans.

Non-interest income. Non-interest income increased $54,000 for the three-month period of 2007 over the comparable 2006 period. This increase of 9.1% was primarily the result of higher service charge revenue associated with an increase in the number of deposit accounts, expanded ATM/Debit card usage, and an increase in revenue from investment services. Additionally, earnings on bank-owned life insurance were $8,000 higher during the second quarter of 2007 than the same period of 2006.

For the six months ended June 30, 2007, non-interest income increased $125,000 or 10.9% to $1.3 million, compared to $1.1 million for the same period in the prior year. This increase is attributed to increases in fees and service charges, earnings on bank-owned life insurance (BOLI) and other income of $84,000, $27,000 and $8,000, respectively. Adding to the increase non-interest income was a $6,000 loss on the sale of investments during the first quarter 2006 which was not duplicated in the same period in 2007.

Non-interest expense. Non-interest expense for the second quarter of 2007 was 22.3%, or $423,000, higher than the second quarter of 2006. Increases in salary and employee benefits of $205,000, occupancy expense of $85,000, and equipment expense of $32,000, were largely attributable to the opening of the Newbury banking office and the Cortland loan production office, as well as the acquisition of Emerald Bank. Non-interest expenses directly attributable to Emerald Bank accounted for $205,000 of the increase in the aggregate. Other associated expense items contributing to the increase were legal, printing, and transfer agent costs, as well as an increase of costs associated with compliance with Section 404 of the Sarbanes-Oxley Act.

For the six months ended June 30, 2007 non-interest expense increased $661,000 or 16.8% for the same period in the prior year.

Provision for income taxes. The Company recognized $398,000 in income tax expense, which reflected an effective tax rate of 19.48% for the six months, ended June 30, 2007, as compared to $695,000 with an effective tax rate of 27.8% for the respective 2006 period.

CRITICAL ACCOUNTING ESTIMATES

The Company’s critical accounting estimates involving the more significant judgments and assumptions used in the preparation of the consolidated financial statements as of June 30, 2007, have remained unchanged from December 31, 2006.

Average Balance Sheet and Yield/Rate Analysis. The following table sets forth, for the periods indicated, information concerning the total dollar amounts of interest income from interest-earning assets and the resultant average yields, the total dollar amounts of interest expense on interest-bearing liabilities and the resultant average costs, net interest income, interest rate spread and the net interest margin earned on average interest-earning assets. For purposes of this table, average balances are calculated using monthly averages and the average loan balances include non-accrual loans and exclude the allowance for loan losses, and interest income includes accretion of net deferred loan fees. Interest and yields on tax-exempt securities (tax-exempt for federal income tax purposes) are shown on a fully tax equivalent basis utilizing a federal tax rate of 34%. Yields and rates have been calculated on an annualized basis utilizing monthly interest amounts.

Analysis of Changes in Net Interest Income. The following tables analyzes the changes in interest income and interest expense, between the three and six month periods ended June 30, 2007 and 2006, in terms of: (1) changes in volume of interest-earning assets and interest-bearing liabilities and (2) changes in yields and rates. The table reflects the extent to which changes in the Company’s interest income and interest expense are attributable to changes in rate (change in rate multiplied by prior period volume), changes in volume (changes in volume multiplied by prior period rate) and changes attributable to the combined impact of volume/rate (change in rate multiplied by change in volume). The changes attributable to the combined impact of volume/rate are allocated on a consistent basis between the volume and rate variances. Changes in interest income on securities reflects the changes in interest income on a fully tax equivalent basis.

LIQUIDITY

Management’s objective in managing liquidity is maintaining the ability to continue meeting the cash flow needs of its customers, such as borrowings or deposit withdrawals, as well as its own financial commitments. The principal sources of liquidity are net income, loan payments, maturing and principal reductions on securities and sales of securities available for sale, federal funds sold and cash and deposits with banks. Along with its liquid assets, the Company has additional sources of liquidity available to ensure that adequate funds are available as needed. These include, but are not limited to, the purchase of federal funds, and the ability to borrow funds under line of credit agreements with correspondent banks and a borrowing agreement with the Federal Home Loan Bank of Cincinnati, Ohio and the adjustment of interest rates to obtain depositors. Management feels that it has the capital adequacy, profitability and reputation to meet the current and projected needs of its customers.

For the six months ended June 30, 2007, the adjustments to reconcile net income to net cash from operating activities consisted mainly of depreciation and amortization of premises and equipment, the provision for loan losses, net amortization of securities and net changes in other assets and liabilities. Cash and cash equivalents increased as a result of the purchasing of government agency securities. For a more detailed illustration of sources and uses of cash, refer to the condensed consolidated statements of cash flows.

INFLATION

Substantially all of the Company’s assets and liabilities relate to banking activities and are monetary in nature. The consolidated financial statements and related financial data are presented in accordance with U.S. GAAP. GAAP currently requires the Company to measure the financial position and results of operations in terms of historical dollars, with the exception of securities available for sale, impaired loans and other real estate loans that are measured at fair value. Changes in the value of money due to rising inflation can cause purchasing power loss.

Management’s opinion is that movements in interest rates affect the financial condition and results of operations to a greater degree than changes in the rate of inflation. It should be noted that interest rates and inflation do effect each other, but do not always move in correlation with each other. The Company’s ability to match the interest sensitivity of its financial assets to the interest sensitivity of its liabilities in its asset/liability management may tend to minimize the effect of changes in interest rates on the Company’s performance.

REGULATORY MATTERS

The Company is subject to the regulatory requirements of The Federal Reserve System as a one-bank holding company. The affiliate bank is subject to regulations of the Federal Deposit Insurance Corporation (FDIC) and the State of Ohio, Division of Financial Institutions.

REGULATORY CAPITAL REQUIREMENTS

The Company is subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and prompt corrective action regulations involve quantitative measures of assets, liabilities and certain off-balance sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators about components, risk weightings and other factors and the regulators can lower classifications in certain cases. Failure to meet various capital requirements can initiate regulatory action that could have a direct material effect on the Banks’ operations.

The prompt corrective action regulations provide five classifications, including well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized, although these terms are not used to represent overall financial condition. If adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion and plans for capital restoration are required.
