NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1.		SIGNIFICANT ACCOUNTING POLICIES
		Basis of Presentation: The unaudited financial statements for the three and six months ended June 30, 2007 include the consolidated results of operations of Mercantile Bank Corporation and its consolidated subsidiaries. These subsidiaries include Mercantile Bank of Michigan (“our bank”), our bank’s three subsidiaries, Mercantile Bank Mortgage Company, LLC (“our mortgage company”), Mercantile Bank Real Estate Co., LLC (“our real estate company”), and Mercantile Insurance Center, Inc. (“our insurance center”). These consolidated financial statements have been prepared in accordance with the instructions for Form 10-Q and Item 303(b) of Regulation S-K and do not include all disclosures required by accounting principles generally accepted in the United States of America for a complete presentation of our financial condition and results of operations. In the opinion of management, the information reflects all adjustments (consisting only of normal recurring adjustments) which are necessary in order to make the financial statements not misleading and for a fair presentation of the results of operations for such periods. The results for the periods ended June 30, 2007 should not be considered as indicative of results for a full year. For further information, refer to the consolidated financial statements and footnotes included in our annual report on Form 10-K for the year ended December 31, 2006.
		We formed a business trust, Mercantile Bank Capital Trust I (“the trust”), in 2004 to issue trust preferred securities. We issued subordinated debentures to the trust in return for the proceeds raised from the issuance of the trust preferred securities. In accordance with FASB Interpretation No. 46, the trust is not consolidated, but instead we report the subordinated debentures issued to the trust as a liability.
		Earnings Per Share: Basic earnings per share is based on weighted average common shares outstanding during the period. Diluted earnings per share include the dilutive effect of additional potential common shares issuable under stock options and the dilutive effect of restricted shares to the extent those shares have not vested. Options for 112,514 shares were antidilutive and were not included in determining diluted earnings per share for the three and six month periods ended June 30, 2007, and options for 7,521 shares were antidilutive and were not included in determining diluted earnings per share for the three and six month periods ended June 30, 2006.
		Stock Dividend: All per share amounts and average shares outstanding have been adjusted for all periods presented to reflect the 5% stock dividend distributed on May 4, 2007. The Statement of Changes in Shareholders’ Equity reflects a transfer from retained earnings to common stock for the value of the shares distributed to the extent of available retained earnings.
		Allowance for Loan and Lease Losses: The allowance for loan and lease losses (“allowance”) is a valuation allowance for probable incurred credit losses, increased by the provision for loan and lease losses and recoveries, and decreased by charge-offs. Management estimates the allowance balance required based on past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, and economic conditions. Allocations of the allowance may be made for specific loans and leases, but the entire allowance is available for any loan or lease that, in management’s judgment, should be charged-off. Loan and lease losses are charged against the allowance when management believes the uncollectibility of a loan or lease balance is likely.

1.		SIGNIFICANT ACCOUNTING POLICIES (Continued)
		A loan or lease is impaired when full payment under the loan or lease terms is not expected. Impairment is evaluated in aggregate for smaller-balance loans of similar nature such as residential mortgage, consumer and credit card loans, and on an individual loan basis for other loans. If a loan or lease is impaired, a portion of the allowance is allocated so that the loan or lease is reported, net, at the present value of estimated future cash flows using the loan’s or lease’s existing rate or at the fair value of collateral if repayment is expected solely from the collateral. Loans and leases are evaluated for impairment when payments are delayed, typically 30 days or more, or when serious deficiencies are identified within the credit relationship.
		New Accounting Pronouncements: We adopted the provisions of FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes (“FIN 48”), on January 1, 2007. The adoption of FIN 48 had no affect on the financial statements. We have no unrecognized tax benefits and do not anticipate any increase in unrecognized benefits during 2007 relative to any tax positions taken prior to January 1, 2007. Should the accrual of any interest or penalties relative to unrecognized tax benefits be necessary, it is our policy to record such accruals in our income tax accounts; no such accruals exist as of June 30, 2007. We file U.S. federal income tax returns which are subject to examination for all years after 2002.
		In September 2006, the FASB issued Statement No. 157, Fair Value Measurements, which provides a definition of fair value for accounting purposes, establishes a framework for measuring fair value, expands related financial statement disclosures and will be effective on January 1, 2008. We have not completed a review of this new standard.
		In February 2007, the FASB issued Statement No. 159, The Fair Value Option for Financial Assets and Financial Liabilities, which permits entities to choose to measure, on an item-by-item basis, specified financial instruments and certain other items at fair value. Unrealized gains and losses on items for which the fair value option has been selected are required to be reported in earnings at each reporting date. Statement No. 159 will be applied prospectively and implemented effective January 1, 2008. We have not completed a review of this new standard.

8.		COMMITMENTS AND OFF-BALANCE-SHEET RISK
		Our bank is a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of our customers. These financial instruments include commitments to extend credit and standby letters of credit. Loan commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Standby letters of credit are conditional commitments issued by our bank to guarantee the performance of a customer to a third party. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements.
		These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized, if any, in the balance sheet. Our bank’s maximum exposure to loan loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual notional amount of those instruments. Our bank uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. Collateral, such as accounts receivable, securities, inventory, and property and equipment, is generally obtained based on management’s credit assessment of the borrower. If required, estimated loss exposure resulting from these instruments is expensed and recorded as a liability. The balance of the liability account was $0.5 million as of June 30, 2007 and December 31, 2006.
		A summary of the contractual amounts of our financial instruments with off-balance-sheet risk at June 30, 2007 and December 31, 2006 follows:

		June 30,				December 31,

9.		REGULATORY MATTERS
		We are 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 our financial statements.
		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 not well 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.
		Our actual capital levels and minimum required levels were (dollars in thousands):

The consolidated capital levels as of June 30, 2007 and December 31, 2006 include the $32.0 million in trust preferred securities issued by the trust subject to certain limitations. Federal Reserve guidelines limit the amount of trust preferred securities which can be included in our Tier 1 capital to 25% of total Tier 1 capital. As of June 30, 2007 and December 31, 2006, all $32.0 million of the trust preferred securities were included as Tier 1 capital.

Our and our bank’s ability to pay cash and stock dividends is subject to limitations under various laws and regulations and to prudent and sound banking practices. We declared a 5% stock dividend on April 10, 2007, that was distributed on May 4, 2007 to record holders as of April 23, 2007. All earnings per share and dividend per share information have been adjusted for the 5% stock dividend. We have also paid two cash dividends on our common stock during 2007. On January 9, 2007, we declared a $0.14 per share cash dividend on our common stock, which was paid on March 9, 2007 to record holders as of February 9, 2007. On April 10, 2007, we declared a $0.14 per share cash dividend on our common stock, which was paid on June 8, 2007 to record holders as of May 10, 2007. On July 10, 2007, we declared a $0.14 per share cash dividend on our common stock, which is payable on September 10, 2007 to record holders as of August 10, 2007.

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

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 our company. Words such as “anticipates”, “believes”, “estimates”, “expects”, “forecasts”, “intends”, “is likely”, “plans”, “projects”, and variations of such words and similar expressions are intended to identify such forward-looking statements. These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions (“Future 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. We undertake no obligation to update, amend, or clarify forward-looking statements, whether as a result of new information, future events (whether anticipated or unanticipated), or otherwise.

Future Factors include, among others, changes in interest rates and interest rate relationships; demand for products and services; the degree of competition by traditional and non-traditional competitors; changes in banking regulations; changes in tax laws; changes in prices, levies, and assessments; the impact of technological advances; governmental and regulatory policy changes; the outcomes of contingencies; trends in customer behavior as well as their ability to repay loans; changes in the national and local economies; and risk factors described in our annual report on Form 10-K for the year ended December 31, 2006. These are representative of the Future Factors that could cause a difference between an ultimate actual outcome and a preceding forward-looking statement.

Introduction
The following discussion compares the financial condition of Mercantile Bank Corporation and its consolidated subsidiaries, Mercantile Bank of Michigan (“our bank”), our bank’s three subsidiaries Mercantile Bank Mortgage Company, LLC (“our mortgage company”), Mercantile Bank Real Estate Co., LLC (“our real estate company”) and Mercantile Insurance Center, Inc. (“our insurance center”), at June 30, 2007 to December 31, 2006 and the results of operations for the three and six months ended June 30, 2007 and June 30, 2006. This discussion should be read in conjunction with the interim consolidated financial statements and footnotes included in this report. Unless the text clearly suggests otherwise, references in this report to “us,” “we,” “our,” or “the company” include Mercantile Bank Corporation and its consolidated subsidiaries referred to above.

Critical Accounting Policies
Generally accepted accounting principles are complex and require management to apply significant judgment to various accounting, reporting and disclosure matters. Management must use assumptions and estimates to apply these principles where actual measurements are not possible or practical. The Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with our unaudited financial statements included in this report. For a complete discussion of our significant accounting policies, see footnotes to our Consolidated Financial Statements included on pages F-35 through F-40 in our Form 10-K for the fiscal year ended December 31, 2006 (Commission file number 000-26719). Below is a discussion of our allowance for loan and lease losses policy. This policy is critical because it is highly dependent upon subjective or complex judgments, assumptions and estimates. Changes in such estimates may have a significant impact on the financial statements, and actual results may differ from those estimates. Management has reviewed the application of this policy with the Audit Committee of our Board of Directors.

MERCANTILE BANK CORPORATION

Allowance for Loan and Lease Losses: The allowance for loan and lease losses (“allowance”) is a valuation allowance for probable incurred credit losses, increased by the provision for loan and lease losses and recoveries, and decreased by charge-offs. Management estimates the allowance balance required based on past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, and economic conditions. Allocations of the allowance may be made for specific loans and leases, but the entire allowance is available for any loan or lease that, in management’s judgment, should be charged-off. Loan and lease losses are charged against the allowance when management believes the uncollectibility of a loan or lease balance is likely.

A loan or lease is impaired when full payment under the loan or lease terms is not expected. Impairment is evaluated in aggregate for smaller-balance loans of similar nature such as residential mortgage, consumer and credit card loans, and on an individual loan basis for other loans. If a loan or lease is impaired, a portion of the allowance is allocated so that the loan or lease is reported, net, at the present value of estimated future cash flows using the loan’s or lease’s existing rate or at the fair value of collateral if repayment is expected solely from the collateral. Loans and leases are evaluated for impairment when payments are delayed, typically 30 days or more, or when serious deficiencies are identified within the credit relationship.

Financial Condition
During the first six months of 2007, our assets increased from $2,067.3 million on December 31, 2006, to $2,103.5 million on June 30, 2007. This represents an increase in total assets of $36.2 million, or 1.8%. The asset growth was comprised primarily of a $29.2 million increase in net loans, a $2.4 million increase in other real estate owned and repossessed assets and a $2.0 million increase in securities. The growth in total assets was primarily funded by a $40.0 million increase in Federal Home Loan Bank advances, partially offset by a $7.9 million decrease in deposits.

Commercial loans and leases increased by $40.2 million during the first six months of 2007, and at June 30, 2007 totaled $1,645.7 million, or 92.7% of the total loan and lease portfolio. The growth in our commercial loan and lease portfolio has slowed over the past several quarters, primarily reflecting the competitive pricing and underwriting environments within our markets. These competitive pressures, from financial institutions and other entities such as private equity funds, have negatively impacted the volume of loans we have booked and accelerated the level of loan payoffs. Despite these competitive pressures, we remain committed to our traditionally high standards of underwriting and believe the long term benefits of this conservative posture outweigh the likely short term negative impact to our net interest income and net income.

The continued significant concentration of the loan and lease portfolio in commercial loans and leases and the typical rapid growth of this portion of our lending business is consistent with our stated strategy of focusing a substantial amount of efforts on “wholesale” banking. Corporate and business lending continues to be an area of expertise of our senior management team, and our commercial lenders have extensive commercial lending experience, with most having at least 10 years’ experience. Of each of the loan categories that we originate, commercial loans and leases are most efficiently originated and managed; thus limiting overhead costs by necessitating the attention of fewer full-time employees. Our commercial lending business generates the greatest amount of local deposits and is our primary source of demand deposits.

MERCANTILE BANK CORPORATION

Residential mortgage loans and consumer loans decreased an aggregate $9.8 million during the first six months of 2007. As of June 30, 2007, residential mortgage and consumer loans totaled a combined $130.3 million, or 7.3% of the total loan and lease portfolio. Although we plan to increase our non-commercial loan portfolios in future periods, we expect the commercial sector of our lending efforts and resultant assets to remain the dominant loan portfolio category given our wholesale banking strategy.

Net loan and lease charge-offs during the first six months of 2007 totaled $2.0 million, or 0.23% of average total loans and leases on an annualized basis. During the first six months of 2006, net loan and lease charge-offs totaled $1.7 million, or 0.22% of average total loans and leases on an annualized basis. Nonperforming assets, including $3.4 million of foreclosed real estate and repossessed assets, totaled $24.0 million, or 1.14% of total assets, as of June 30, 2007. At March 31, 2007, non-performing assets totaled $12.6 million, or 0.60% of total assets, including $2.5 million of foreclosed real estate and repossessed assets. At June 30, 2006, non-performing assets totaled $8.7 million, or 0.44% of total assets, including $0.2 million of foreclosed real estate and repossessed assets. The majority of the recent increase in non-performing assets can be attributed to two loans totaling $8.0 million that were placed into non-accrual status during the second quarter of 2007. Over 90 percent of non-performing loans are collateralized by real estate; although the resolution of distressed real estate loans is a relatively lengthy process, we believe we are adequately reserved as present market conditions stand.

We believe we have instilled a strong credit culture within our lending departments as it pertains to the underwriting and administration processes, which in part is reflected in our historically low loan and lease net charge-off and delinquency ratios. Over 98% of the loan portfolio consists of loans extended directly to companies and individuals doing business and residing within our market area. The remaining portion is primarily comprised of commercial loans participated with certain commercial banks outside the immediate area, which we underwrite using the same loan underwriting criteria as though our bank was the originating bank.

Securities increased $2.0 million during the first six months of 2007, totaling $204.4 million as of June 30, 2007. Purchases during the first six months of 2007 totaled $10.9 million, while proceeds from maturities, calls and repayments of securities totaled $6.0 million. Our securities portfolio primarily consists of U.S. Government Agency bonds, mortgage-backed securities issued or guaranteed by U.S. Government Agencies, investment-grade tax-exempt municipal securities and Federal Home Loan Bank of Indianapolis (“FHLBI”) stock.

Cash and cash equivalents decreased $2.9 million during the first six months of 2007, totaling $48.4 million on June 30, 2007. Cash and due from bank balances were down $2.9 million, while short-term investments were unchanged. We did not have federal funds sold on either June 30, 2007 or December 31, 2006; however, our average federal funds sold position during the first six months of 2007 equaled $6.7 million. Our commercial lending and wholesale funding focus results in relatively large day-to-day fluctuations of our cash and cash equivalent balances. The average cash and cash equivalents during the first six months of 2007 equaled $45.5 million.

Premises and equipment at June 30, 2007 equaled $34.8 million, an increase of $1.3 million over the past six months. Purchases of premises and equipment during the first six months of 2007 totaled $2.6 million, primarily reflecting a portion of the construction costs associated with our new banking facility located in East Lansing, Michigan, which opened in May 2007. Depreciation expense during the first six months of 2007 equaled $1.3 million.

MERCANTILE BANK CORPORATION

Deposits decreased $7.9 million during the first six months of 2007, totaling $1,639.0 million at June 30, 2007. Local deposits decreased $3.5 million, while out-of-area deposits decreased $4.4 million. As a percent of total deposits, local deposits equaled 38.4% on June 30, 2007, unchanged from the level as of December 31, 2006. Noninterest-bearing demand deposits, comprising 7.6% of total deposits, decreased $8.2 million during the first six months of 2007. Savings deposits (5.1% of total deposits) decreased $9.3 million, interest-bearing checking deposits (2.1% of total deposits) decreased $4.9 million and money market deposit accounts (0.7% of total deposits) increased $2.0 million during the first six months of 2007. Local certificates of deposit, comprising 22.9% of total deposits, increased $17.0 million during the first six months of 2007. The increase in local certificates of deposit is primarily attributable to increases in balances from municipalities and transfers of monies by consumer and commercial customers from savings accounts to certificate of deposit products, the latter of which primarily reflecting that rates offered on certificates of deposit products are higher than the rates offered on savings accounts. Our commercial lending and wholesale funding focus results in relatively large day-to-day fluctuations of our noninterest-bearing demand deposits and to a lesser degree our savings deposits.

Out-of-area deposits decreased $4.4 million during the first six months of 2007, totaling $1,009.4 million as of June 30, 2007. Out-of-area deposits consist primarily of certificates of deposit obtained from depositors located outside our market area and placed by deposit brokers for a fee, but also include certificates of deposit obtained from the deposit owners directly. Out-of-area deposits are utilized to support our asset growth, and are generally a lower cost source of funds when compared to the deposit interest rates that would have to be offered in the local market to generate a sufficient level of funds. During the first six months of 2007, rates paid on new out-of-area certificates of deposit were similar to the rates paid on new certificates of deposit issued to local customers. Overhead costs associated with the out-of-area deposits are considerably less than the overhead costs that would be incurred to administer a similar level of local deposits. Although local deposits generally have and are expected to increase as new business, governmental and consumer deposit relationships are established, our relatively high reliance on out-of-area deposits is expected to continue.

Securities sold under agreements to repurchase (“repurchase agreements”) decreased by $0.5 million during the first six months of 2007, totaling $85.0 million as of June 30, 2007. As part of our sweep account program, collected funds from certain business noninterest-bearing checking accounts are invested into over-night interest-bearing repurchase agreements. Although not considered a deposit account and therefore not afforded federal deposit insurance, the repurchase agreements have characteristics very similar to that of our business checking deposit accounts.

Advances obtained from the FHLBI totaled $135.0 million as of June 30, 2007, an increase of $40.0 million from the $95.0 million outstanding as of December 31, 2006. The FHLBI advances are collateralized by residential mortgage loans, first mortgage liens on multi-family residential property loans and first mortgage liens on commercial real estate property loans, and substantially all other assets of our bank, under a blanket lien arrangement. Our borrowing line of credit as of June 30, 2007 totaled $313.8 million, with availability approximating $167.9 million. FHLBI advances, along with out-of-area deposits, are the primary components of our wholesale funding program.

Liquidity
Liquidity is measured by our ability to raise funds through deposits, borrowed funds, capital or cash flow from the repayment of loans and securities. These funds are used to meet deposit withdrawals, maintain reserve requirements, fund loans and securities, and support our operations. Liquidity is primarily achieved through the growth of deposits (both local and out-of-area), advances from the FHLBI and federal funds purchased, as well as liquid assets such as securities available for sale, matured securities, and federal funds sold. Asset and liability management is the process of managing our balance sheet to achieve a mix of earning assets and liabilities that maximizes profitability, while providing adequate liquidity.

Our liquidity strategy is to fund asset growth with deposits, repurchase agreements and FHLBI advances and to maintain an adequate level of short- and medium-term investments to meet typical daily loan and deposit activity. Although deposit and repurchase agreement growth from depositors located in our market area has generally consistently increased, this growth has not been sufficient to meet our substantial loan growth and provide monies for additional investing activities. To assist in providing the additional needed funds, we have regularly obtained monies from wholesale funding sources. Wholesale funds, comprised of certificates of deposit from customers outside of our market area and advances from the FHLBI, totaled $1,144.4 million, or 61.1% of combined deposits and borrowed funds as of June 30, 2007. As of December 31, 2006, wholesale funds totaled $1,108.8 million, or 60.2% of combined deposits and borrowed funds. Reliance on wholesale funds is expected to continue due to our anticipated future asset growth.

As a member of the FHLBI, our bank has access to the FHLBI’s borrowing programs. At June 30, 2007, advances from the FHLBI totaled $135.0 million, up from the $95.0 million outstanding as of December 31, 2006. Based on available collateral at June 30, 2007, our bank could borrow an additional $167.9 million.

Our bank has the ability to borrow money on a daily basis through correspondent banks via established unsecured federal funds purchased lines, totaling $72.0 million as of June 30, 2007. The average balance of federal funds purchased during the first six months of 2007 equaled $4.6 million, compared to a $6.7 million average federal funds sold position during the same time period.

In addition to typical loan funding and deposit flow, we must maintain liquidity to meet the demands of certain unfunded loan commitments and standby letters of credit. As of June 30, 2007, our bank had a total of $490.1 million in unfunded loan commitments and $84.4 million in unfunded standby letters of credit. Of the total unfunded loan commitments, $413.6 million were commitments available as lines of credit to be drawn at any time as customers’ cash needs vary, and $76.5 million were for loan commitments expected to close and become funded within the next twelve months. We monitor fluctuations in loan balances and commitment levels and include such data in managing our overall liquidity.

Capital Resources
Shareholders’ equity is a noninterest-bearing source of funds that provides support for asset growth. Shareholders’ equity increased by $2.6 million during the first six months of 2007, from $171.9 million on December 31, 2006, to $174.5 million at June 30, 2007. The increase is primarily attributable to net income of $6.5 million recorded during the first six months of 2007. Shareholders’ equity also increased $0.1 million from the issuance of new shares of common stock resulting from our dividend reinvestment plan, employee stock purchase plan and stock option exercises. Shareholders’ equity was negatively impacted during the first six months of 2007 by the payment of cash dividends totaling $2.3 million and a $1.9 million mark-to-market adjustment for available for sale securities as defined in SFAS No. 115.

We are subject to regulatory capital requirements primarily administered by federal bank regulatory agencies. Failure to meet the various capital requirements can initiate regulatory action that could have a direct material effect on the financial statements. The capital ratios of the company and our bank as of June 30, 2007 and December 31, 2006 are disclosed under Note 9 of the Notes to Consolidated Financial Statements.

Our and our bank’s ability to pay cash and stock dividends is subject to limitations under various laws and regulations and to prudent and sound banking practices. We declared a 5% stock dividend on April 10, 2007, that was distributed on May 4, 2007 to record holders as of April 23, 2007. All earnings per share and dividend per share information have been adjusted for the 5% stock dividend. We paid a $0.14 per share cash dividend on March 9, 2007 and on June 8, 2007. On July 10, 2007, we declared a $0.14 per share cash dividend payable on September 10, 2007 to record holders as of August 10, 2007.

Results of Operations
Net income for the second quarter of 2007 was $2.2 million ($0.26 per basic and diluted share), which represents a 56.5% decrease from net income of $5.1 million ($0.61 per basic share and $0.60 per diluted share) recorded during the second quarter of 2006. Net income for the first six months of 2007 was $6.5 million ($0.77 per basic and diluted share), which represents a 35.2% decrease from net income of $10.0 million ($1.20 per basic share and $1.18 per diluted share) recorded during the first six months of 2006. The decline in net income during both time periods is primarily the result of lower net interest income and a higher provision for loan and lease losses. In addition, net income for the second quarter of 2007 and the first six months of 2007 include a one-time $1.2 million ($0.8 million after-tax) expense associated with the financial retirement package for former Chairman and Chief Executive Officer, Gerald Johnson Jr., which was recorded during the second quarter of 2007 in conjunction with Mr. Johnson’s retirement effective June 30, 2007. Excluding this one-time expense, net income for the second quarter of 2007 was $3.0 million ($0.36 per basic and diluted share), while net income for the first six months of 2007 was $7.3 million ($0.86 per basic and diluted share).

Interest income during the second quarter of 2007 was $36.1 million, an increase of 6.9% over the $33.7 million earned during the second quarter of 2006. Interest income during the first six months of 2007 was $72.1 million, an increase of 11.2% over the $64.8 million earned during the first six months of 2006. The growth in interest income during both time periods is primarily attributable to growth in earning assets. During the second quarter of 2007, earning assets averaged $1,965.3 million, $123.6 million higher than average earning assets of $1,841.7 million during the second quarter of 2006. Average loans were up $112.0 million and average securities increased $16.6 million. During the first six months of 2007, earning assets averaged $1,959.4 million, $149.0 million higher than average earning assets of $1,810.4 million during the same time period in 2006. Average loans were up $135.8 million and average securities increased $18.1 million. During the second quarter of 2007 and 2006, earning assets had an average yield (tax equivalent-adjusted basis) of 7.43% and 7.42%, respectively. During the first six months of 2007 and 2006, earning assets had an average yield of 7.48% and 7.29%, respectively. With approximately 65% of our total loans and leases tied to the prime rate, our asset yield has benefited from increases in the prime rate. Between January 1, 2006 and June 30, 2006, the Federal Open Market Committee raised the target federal funds rate by a total of 100 basis points, with the prime rate increasing by the same magnitude. During the period of June 30, 2004 through June 30, 2006, the target federal funds rate was increased a total of 425 basis points. In comparison to the average yield on assets during the second quarter of 2006, the average yield on assets during the second quarter of 2007 was lower by about 6 basis points due to an increase in non-performing assets.

Interest expense during the second quarter of 2007 was $22.1 million, an increase of 22.3% over the $18.1 million expensed during the second quarter of 2006. Interest expense during the first six months of 2007 was $43.7 million, an increase of 28.1% over the $34.1 million expensed during the first six months of 2006. The growth in interest expense is primarily attributable to an increase in interest-bearing liabilities necessitated by asset growth and a higher interest rate environment. During the second quarter of 2007, interest-bearing liabilities averaged $1,759.1 million, $114.3 million higher than average interest-bearing liabilities of $1,644.8 million during the second quarter of 2006. Average interest-bearing deposits were up $123.2 million and average short-term borrowings increased $11.4 million, partially offset by a $20.8 million decline in average FHLBI advances. During the first six months of 2007, interest-bearing liabilities averaged $1,754.3 million, $137.6 million higher than average interest-bearing liabilities of $1,616.7 million during the same time period in 2006. Average interest-bearing deposits were up $153.8 million and average short-term borrowings increased $12.4 million, while average FHLBI advances declined $29.4 million. During the second quarter of 2007 and 2006, interest-bearing liabilities had an average rate of 5.05% and 4.41%, respectively. During the first six months of 2007 and 2006, interest-bearing liabilities had an average rate of 5.02% and 4.25%, respectively. The higher average cost of interest-bearing liabilities is primarily due to the increase in market interest rates.

Net interest income during the second quarter of 2007 was $13.9 million, a decrease of 10.9% from the $15.6 million earned during the second quarter of 2006. Net interest income during the first six months of 2007 was $28.4 million, a decrease of 7.5% from the $30.7 million earned during the same time period in 2006. The decrease in net interest income during both time periods was primarily due to a decline in the net interest margin, which more than offset the positive impact from growth in earning assets. The net interest margin during the second quarter of 2007 was 2.91%, compared to 3.47% during the second quarter of 2006. During the first six months of 2007, the net interest margin was 2.99%, compared to 3.49% during the same time period in 2006. The decline in our net interest margin during both time periods primarily reflects our cost of funds increasing more than the improvement in our yield on assets. During the first six months of 2006, our yield on assets increased in conjunction with the increase in the prime rate. However, our yield on assets has remained relatively stable since then, reflecting the unchanged prime rate since June 30, 2006. Our cost of funds increased during the first six months of 2006, reflecting the increase in market interest rates. While deposit and borrowed fund rates have also remained relatively stable since June 30, 2006, our cost of funds has continued to increase as maturing fixed rate certificates of deposit and FHLBI advances that were originated in lower interest rate environments are renewed or replaced with similar products in the current higher interest rate environment.

The following table sets forth certain information relating to our consolidated average interest-earning assets and interest-bearing liabilities and reflects the average yield on assets and average cost of liabilities for the second quarter of 2007 and 2006. Such yields and costs are derived by dividing income or expense by the average daily balance of assets or liabilities, respectively, for the period presented. Tax-exempt securities interest income and yield have been computed on a tax equivalent basis using a marginal tax rate of 35%. Securities interest income was increased by $300,000 and $301,000 in the second quarter of 2007 and 2006, respectively, for this adjustment.
