MIDDLEFIELD BANC CORP.

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, 2005, 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.

NOTE 2 – STOCK-BASED COMPENSATION

The Company maintains a stock option plan for key officers, employees, and non-employee directors. Had compensation expense for the stock option plans been recognized in accordance with the fair value accounting provisions of FAS No. 123,Accounting for Stock-Based Compensation, net income applicable to common stock, basic, and diluted net income per common share would have been as follows:

	Three Months Ended March 31,
	2005
Net income, as reported:	$	714,090
Less proforma expense related to stock options		12,750
Proforma net income	$	701,340
Basic net income per common share:
As reported	$	0.54
Pro forma		0.53
Diluted net income per common share:
As reported	$	0.53
Pro forma		0.52

For purposes of computing pro forma results, the Company estimated the fair values of stock options using the Black-Scholes option-pricing model. The model requires the use of subjective assumptions that can materially affect fair value estimates. Therefore, the pro forma results are estimates of results of operations as if compensation expense had been recognized for the stock option plans.

As of March 31, 2006, there was no unrecognized compensation cost related to unvested share-based compensation awards granted.

Stock option activity during the three months ended March 31, 2006 is as follows:

Outstanding, March 31		70,189		$	28.28

NOTE 3 — EARNINGS PER SHARE

Middlefield provides dual presentation of Basic and Diluted earnings per share. Basic earnings per share utilize net income as reported as the numerator and the actual average shares outstanding as the denominator. Diluted earnings per share include 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.

	Months Ended

Additional common stock equivalents (stock options) used to calculate diluted earnings per share		21,467			7,157
Weighted average common shares and common stock equivalents used to calculate diluted earnings per share		1,368,931			1,336,957

NOTE 4 – COMPREHENSIVE INCOME

The components of comprehensive income consist exclusively of unrealized gains and losses on available for sale securities. For the three months ended March 31, 2006, this activity is shown under the heading Comprehensive Income as presented in the Consolidated Statement of Changes in Stockholders’ Equity (Unaudited). For the three months ended March 31, 2005, comprehensive income totaled $747,595.

The following shows the components and activity of comprehensive income during the periods ended March 31, 2006 and 2005 (net of the income tax effect):

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

Forward Looking Statements

     When used in this Form 10-Q, or in future filings with the Securities and Exchange Commission, in press releases or other public or shareholder communications, or in oral statements made with the approval of an authorized executive officer, the words or phrases “will likely result”, “are expected to”, “will continue”, “is anticipated”, “estimate”, “project”, or similar expressions are intended to identify “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements involve known and unknown risks, uncertainties and other factors, which may cause the Corporation’s actual results to be materially different from those indicated. Such statements are subject to certain risks and uncertainties including changes in economic conditions in the market areas the Corporation conducts business, which could materially impact credit quality trends, changes in policies by regulatory agencies, fluctuations in interest rates, demand for loans in the market areas the Corporation conducts business, and competition, that could cause actual results to differ materially from historical earnings and those presently anticipated or projected. The Corporation wishes to caution readers not to place undue reliance on any such forward-looking statements, which speak only as of the date made. The Corporation undertakes no obligation to publicly release the result of any revisions that may be made to any forward-looking statements to reflect events or circumstances after the date of such statements or to reflect the occurrence of anticipated or unanticipated events.

CHANGES IN FINANCIAL CONDITION

General.The Company’s total assets increased by $1.4 million or .44% from December 31, 2005 to $312.6 million at March 31, 2006. Cash and cash equivalents, loans receivable, bank owned life insurance and accrued interest and other assets increased $438,000, $1.7 million, $1.1 million and $232,000, respectively. The increase in total assets reflects a corresponding increase in total liabilities of $760,000 or .27% and an increase in stockholders’ equity of $602,000 or 2.2%. The increase in total liabilities was primarily the result of increases in deposits of $4.8 million, partially offset by decreases to short-term borrowing, other borrowing and accrued interest and other liabilities of $2.6 million, $1.4 million, and $121,000, respectively. The increase in stockholders’ equity was the result of increases in retained earnings and common stock of $501,000 and $227,000, respectively. These increase were partially offset by decreases in comprehensive loss and treasury stock of $70,000, and $56,000, respectively.

Cash on hand and due from banks.Cash on hand and due from banks represent cash equivalents. Cash equivalents increased a combined $438,000 or 7.5% to $6.3 million at March 31, 2006 from $5.8 million at December 31, 2005. 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, purchase of bank-owned life insurance, security purchases and repayments of borrowed funds. The increase for the quarter ended March 31, 2006 can principally be attributed to increases in deposits.

Securities.Securities available for sale decreased by $2.0 million or 3.5% to $55.9 million at March 31, 2006 from $57.9 million at December 31, 2005. During the quarter ended March 31, 2006 the Company recorded purchases of available for sale securities of $101,000, consisting of purchases municipal bonds. Offsetting the purchases of securities were repayments and maturities of securities of $1.3 million along with security sales of $700,000 during the three months ended March 31, 2006. In addition, the securities portfolio decreased approximately $106,000 due to decreases 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. Loans receivable increased $1.7 million or .7% to $235.8 million at March 31, 2006 from $234.1 million at December 31, 2005. Included in this increase were increases in commercial loans of $1.1 million or 1.6% and mortgage loans of $1.0 million or .8%, as well as decreases in home equity loans of $336,000 and consumer loans of $266,000 during the three months ended March 31, 2006.

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 $2.1 million or 0.87% and $1.7 million or 0.73% of total loans at March 31, 2006 and December 31, 2005, respectively. The level of non-performing loans remains relatively high in comparison to the bank’s historical levels, however, one large commercial credit constitutes the bulk of the dollar total. Senior credit personnel remain committed to resolving the issue within an expedient timeframe. Our expectations are for nominal losses, should there be any.

Deposits.The Company considers various sources when evaluating funding needs, including but not limited to deposits, which are a significant source of funds totaling $254.3 million or 89.7% of the Company’s total funding sources at March 31, 2006. Total deposits increased $4.8 million or 1.9% to $254.3 million at March 31, 2006 from $249.4 million at December 31, 2005. The increase in deposits is primarily related to the growth of certificates of deposits that totaled $127.2 million at March 31, 2006 an increase of $6.5 million or 5.4% for the year. Interest-bearing demand accounts increased $2.0 million, or 21.2 %, while noninterest-bearing demand deposit and money market accounts decreased $220,000, or .6%, and $10,000, or .1, respectively, during the three months ended March 31, 2006.

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 and repurchase agreements. Borrowed funds decreased $3.9 million or 11.8% to $29.4 million at March 31, 2006 from $33.3 million at December 31, 2005. FHLB advances decreased $1.3 million or 5.1% while short-term borrowings decreased $2.6 million or 38.6%. The decrease in FHLB advances is a result of the increase in the Company’s deposits.

Stockholders’ equity.Stockholders’ equity increased $602,000 or 2.2% to $27.9 million at March 31, 2006 from $27.3 million at December 31, 2005. The increase in stockholders’ equity was the result of increases in common stock and retained earnings of $227,000 and $501,000, respectively offset by an increase in accumulated other comprehensive loss of $70,000. The increase in common stock was due in part to activity of the dividend reinvestment program of $175,000 along with purchases of stock options totaling $52,000 for the quarter. The increase in stock due to the dividend reinvestment program was made up of optional cash payments totaling $107,000 along with $68,000 of reinvested dividends. The increase of accumulated other comprehensive loss was the result of a decrease in the mark to market of the Company’s

securities available for sale portfolio. The increase in treasury stock was the result of the purchase of 1,361 shares of common stock at a price of $41.00 a share.

RESULTS OF OPERATIONS

General.The Company recorded net income of $818,000 for the three months ended March 31, 2006, as compared to net income of $714,000 for the same period in the prior year. The $103,000 or 14.5% increase in net income for the three months ended March 31, 2006, as compared to the three months ended March 31, 2005, was primarily attributable to an increase in net interest income and non-interest income of $118,000 and $69,000, respectively. These items were partially offset by increases in non-interest expense of $23,000 a net change in the provision for loan losses of $15,000 and an increase in provisions for income taxes of $46,000.

Net interest income.Net interest income, the primary source of revenue growth for the Company, is defined as the difference between income on earning assets and the cost of funds supporting those assets. 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. Net interest income increased $118,000 or 4.6% to $2.7 million for the three months ended March 31, 2006, compared to $2.6 million for the same period in the prior year. This increase in net interest income can be attributed to an increase in interest income of $445,000 partially offset by an increase in interest expense $327,000. The net interest margin remained the same during the first quarter of 2006 even with the increase in interest rates. This change in interest rates resulted in a growth in the cost of funds of 37 basis points to 3.07% for the quarter ended March 31, 2006, compared to 2.70% for the same period in the prior year. This increase in the cost of funds negatively impacted net interest income but was offset by an increase in the yield on interest earning assets of 34 basis points to 6.49% for the quarter ended March 31, 2005, compared to 6.15% for the same period in the prior year.

Interest income.Interest income increased $445,000 or 10.8% to $4.6 million for the three months ended March 31, 2006, compared to $4.1 million for the same period in the prior year. This increase can be attributed to interest and fees on loans which was $443,000 higher than the same period in 2005.

Interest and fees on loans increased $443,000 or 12.5 to $4.0 million for the quarter ended March 31, 2006, compared to $3.5 million for the same period in the prior year. This increase was attributable to a increase in the average balance of loans receivable of $16.8 million or 7.7% to $233.7 million for the three months ended March 31, 2006, as compared to $216.9 million for the same period in the prior year.

Interest earned on securities increased slightly by $4,000 or .7% to $551,000 for the three months ended March 31, 2006, compared to $547,000 for the same period in the prior year. This increase in earnings was the result of an increase in market rate as the average balance remained unchanged.

Interest expense.Interest expense increased $327,000 or 21.1% to $1.9 million for the three months ended March 31, 2006, compared to $1.6 million for the same period in the prior year. This increase in interest expense can be primarily attributed to increases in interest incurred on deposits and borrowed funds of $246,000 and $81,000 million, respectively.

Interest incurred on deposits increased $246,000 or 19.0% to $1.5 million for the three months ended March 31, 2006, compared to $1.3 million for the same period in the prior year. This increase was primarily attributable to an increase in the average balance of deposits of $4.3 million to $212.2 million for the three months ended March 31, 2006 from $207.9 million for the same period in the prior year.

Interest incurred on borrowed funds increased $81,000 or 32.2% to $334,000 for the three months ended March 31, 2006, compared to $252,000 million for the same period in the prior year. This increase was primarily attributable to an increase in the average balance of borrowed funds of $10.9 million or 44.0% to $35.6 million for the three months ended March 31, 2006, compared to $24.7 million for the same period in the prior year.

Provision for loan losses.The provision for loan losses for the quarter ended March 31, 2006 is the result of normal operations for the quarter. In determining the appropriate level of allowance for loan losses, management considers historical loss experience, the financial condition of borrowers, economic conditions (particularly as they relate to markets where the Company originates loans), the status of non-performing assets, the estimated underlying value of the collateral and other factors related to the collectability of the loan portfolio. The Company’s total allowance for losses on loans at March 31, 2006 and December 31, 2005 amounted to $2.9 million or 1.23% and $2.8 million or 1.21%, respectively, of the Company’s total loan portfolio. The Company’s allowance for losses on loans as a percentage of non-performing loans was 121.4% and 165.9% at March 31, 2006 and December 31, 2005, respectively.

Non-interest income.Non-interest income increased $69,000 or 14.4% to $550,000 for the three months ended March 31, 2006, compared to $481,000 for the same period in the prior year. This increase can be attributed primarily to increases in fees and service charges and other income of $59,000 and $13,000, respectively. Partially offsetting these increases was a increase in losses on investment securities of $6,000.

Fees and service charges increased $59,000 or 16.8% to $413,000 for the three months ended March 31, 2006, compared to $353,000 for the same period in the prior year. The increase to fees generated from checking accounts is a result of the continued growth in fees from overdraft services.

Non-interest expense.Non-interest expense increased $23,000 or 1.1% to $2.0 million for the three months ended March 31, 2006, from $2.0 million for the same period in the prior year. This increase was the result of increases in occupancy, data processing and other expenses of $19,000, $30,000 and $11,000, respectively. The leading factor in the increased expenses was data processing costs associated with an expanded base of products per customer, as well as the introduction during 2005 of the company’s image based item processing system. Also contributing were the cost of certain maintenance contracts, seasonal utility costs, and depreciation.

Provision for income taxes.The Company recognized $308,000 in income tax expense, which reflected an effective tax rate of 27.4% for the three months, ended March 31, 2006, as compared to $262,000 with an effective tax rate of 26.8% for the respective 2005 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 March 31, 2006, have remained unchanged from December 31, 2005.

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. 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 table analyzes the changes in interest income and interest expense, between the quarters ended March 31, 2006 and 2005, 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 three months ended March 31, 2006, 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.

The minimum requirements are:

	Total			Tier 1			TIER 1
	Capital to			Capital to			Capital to
	Risk-Weighted			Risk-Weighted			Average
	Assets			Assets			Assets
Well capitalized		10.00	%		6.00	%		5.00	%
Adequately capitalized		8.00	%		4.00	%		4.00	%
Undercapitalized		6.00	%		3.00	%		3.00	%

The following table illustrates the Company’s risk-weighted capital ratios at March 31, 2006:

	March 31,
(in thousands)	2006

Item 3 Quantitative and Qualitative Disclosures about Market Risk

ASSET AND LIABILITY MANAGEMENT

The primary objective of the Company’s asset and liability management function is to maximize the Company’s net interest income while simultaneously maintaining an acceptable level of interest rate risk given the Company’s operating environment, capital and liquidity requirements, performance objectives and overall business focus. The principal determinant of the exposure of the Company’s earnings to interest rate risk is the timing difference between the repricing and maturity of interest-earning assets and the repricing or maturity of its interest-bearing liabilities. The Company’s asset and liability management policies are designed to decrease interest rate sensitivity primarily by shortening the maturities of interest-earning assets while at the same time extending the maturities of interest-bearing liabilities. The Board of Directors of the Company continues to believe in strong asset/liability management in order to insulate the Company from material and prolonged increases in interest rates. As a result of this policy, the Company emphasizes a larger, more diversified portfolio of residential mortgage loans in the form of mortgage-backed securities. Mortgage-backed securities generally increase the quality of the Company’s assets by virtue of the insurance or guarantees that back them, are more liquid than individual mortgage loans and may be used to collateralize borrowings or other obligations of the Company.

The Company’s Board of Directors has established an Asset and Liability Management Committee consisting of four outside directors, the President and Chief Executive Officer, Executive/Vice President/ Chief Operating Officer, Senior Vice President/Chief Financial Officer and Senior Vice President/Commercial Lending. This committee, which meets quarterly, generally monitors various asset and liability management policies and strategies, which were implemented by the Company over the past few years. These strategies have included: (i) an emphasis on the investment in adjustable-rate and shorter duration mortgage-backed securities; (ii) an emphasis on the origination of single-family residential adjustable-rate mortgages (ARMs), residential construction loans and commercial real estate loans, which generally have adjustable or floating interest rates and/or shorter maturities than traditional single-family residential loans, and consumer loans, which generally have shorter terms and higher interest rates than mortgage loans; (iii) increase the duration of the liability base of the Company by extending the maturities of savings deposits, borrowed funds and repurchase agreements.

The Company has established the following guidelines for assessing interest rate risk:

Net interest income simulation.Given a 200 basis point parallel and gradual increase or decrease in market interest rates, net interest income may not change by more than 10% for a one-year period.

Portfolio equity simulation.Portfolio equity is the net present value of the Company’s existing assets and liabilities. Given a 200 basis point immediate and permanent increase or decrease in market interest rates, portfolio equity may not correspondingly decrease or increase by more than 20% of stockholders’ equity.

The following table presents the simulated impact of a 200 basis point upward and a 200 basis point downward shift of market interest rates on net interest income and the change in portfolio equity. This analysis was done assuming that the interest-earning asset and interest-bearing liability levels at March 31, 2006 remained constant. The impact of the market rate movements was developed by simulating the effects of rates changing gradually over a one-year period from the March 31, 2006 levels for net interest income. The impact of market rate movements was developed by simulating the effects of an immediate and permanent change in rates at March 31, 2006 for portfolio equity:

	Increase			Decrease
	+200			-200
	BP			BP
Net interest income — increase (decrease)		5.7	%		(6.7	)%
Portfolio equity — increase (decrease)		(3.1	)%		.85	%
