NOTE 1 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation: The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Macatawa Bank, and its wholly-owned subsidiary, Macatawa Bank Mortgage Company; and Macatawa Investment Services, Inc. All significant intercompany accounts and transactions have been eliminated in consolidation.

The Company also owns all of the common stock of Macatawa Statutory Trust I and Macatawa Statutory Trust II. These are grantor trusts that issued trust preferred securities and are not consolidated with the Company per FASB Interpretation No. 46.

Basis of Presentation: The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of management, all adjustments (consisting only of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three month periods ended March 31, 2006, are not necessarily indicative of the results that may be expected for the year ending December 31, 2006. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s 2005 Annual Report containing financial statements for the year ended December 31, 2005.

All per share amounts and average shares outstanding have been adjusted for all periods presented to reflect the 5% stock dividend to be distributed on May 30, 2006, the 3-for-2 stock split to be distributed on June 29, 2006, and the 15% stock dividend distributed on May 27, 2005.

Stock Compensation: On January 1, 2006, the Company adopted FAS 123, Revised, which requires all public companies to record compensation cost for stock options provided to employees in return for employee service. The cost is measured at the fair value of the options when granted, and this cost is expensed over the employee service period, which is normally the vesting period of the options. As amended, this applies to awards granted or modified beginning with the first quarter of 2006. Compensation cost was also recorded for prior option grants that vested after the date of adoption. For the three months ended March 31, 2006, the Company recorded compensation cost for stock options of $188,000, or $147,000 after taxes, representing $.01 per share. Future compensation cost for stock options is expected to be recognized as follows (in thousands):

Employee compensation expense under stock option plans was reported using the intrinsic value method for the three month period ended March 31, 2005. No compensation cost related to stock options was recognized during the three month period March 31, 2005, as all options granted had an exercise price equal to or greater than the market price of the underlying common stock at date of grant. Had compensation cost for stock options been measured using the fair value method, net income and basic and diluted earnings per share would have been the pro forma amounts indicated below (dollars in thousands).

Securities with unrealized losses at March 31, 2006 and December 31, 2005, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, are as follows: (in thousands)

For unrealized losses on securities, no loss has been recognized into income because management has the intent and ability to hold these securities for the foreseeable future and the declines are largely due to differences in market interest rates as compared to those of the underlying securities. The declines in fair value are considered temporary and are expected to recover as the bonds approach their maturity date.

NOTE 6 — STOCK OPTIONS

Options to buy stock are granted to officers and employees under the Employee Stock Option Plan (the Employees’ Plan), which provides for issue of up to 1,038,390 options. Options are also granted to directors under the Directors’ Stock Option Plan (the Directors’ Plan), which provides for issuance of up to 293,241 options. The exercise price is the market price at the date of grant for all plans. The maximum option term is ten years. The vesting schedule is over a one-year period for both the Employees’ Plan and the Directors’ Plan for all grants through the third quarter of 2005. Beginning with grants in the fourth quarter of 2005, the vesting schedule was increased to three years. Upon exercise of stock options, the Company issues new shares from its authorized but unissued shares. The amount of options available for future grant at March 31, 2006 is 83,554. All per share amounts and average shares outstanding have been adjusted for all periods presented to reflect the 5% stock dividend to be distributed on May 30, 2006, the 3-for-2 stock split to be distributed on June 29, 2006, and the 15% stock dividend distributed on May 27, 2005.

A summary of option activity in the plans is as follows: (dollars in thousands)

There were no options granted during the three months ended March 31, 2006. The weighted-average fair value of the 5,435 options granted during the three months ended March 31, 2005 was $4.39 per share. The total intrinsic value of options exercised during the three months ended March 31, 2006 and 2005 was $1.3 million and $630,000, respectively. The total fair value of options vested during the three months ended March 31, 2006 was $23,860. No options vested during the three months ended March 31, 2005.

NOTE 7 — EARNINGS PER SHARE

A reconciliation of the numerators and denominators of basic and diluted earnings per share for the three month periods ended March 31, 2006 and 2005 are as follows (dollars in thousands):

Stock options for 170,888 and 5,434 shares of common stock were not considered in computing diluted earnings per share for the quarters ended March 31, 2006 and March 31, 2005, respectively, because they were antidilutive.

NOTE 8 – CONTINGENCIES

The Company and its subsidiaries periodically become defendants in certain claims and legal actions arising in the ordinary course of business.

On July 8, 2003, the Company filed a Form 8-K (dated July 1, 2003) with the Securities and Exchange Commission reporting events related to a former trust customer, Trade Partners, Inc. (“Trade Partners”), of the former Grand Bank, which the Company acquired effective April 1, 2002. Trade Partners was involved in purchasing and selling interests in viaticals, which are interests in life insurance policies of the terminally ill or elderly. Beginning in 1996, Grand Bank served as a custodian and escrow agent with respect to viaticals purchased by Trade Partners and sold to investors. Two lawsuits were filed, one in December 2002 and another in March 2003, against Trade Partners, Grand Bank and the Company alleging that Grand Bank breached certain escrow agreements related to viatical settlement contracts. Both of these lawsuits have been dismissed although the plaintiffs reserved the right to pursue the claims in the future. A third lawsuit was filed in April 2003 by two individual investors against Grand Bank, the Company, Trade Partners and certain individuals and entities associated with Trade Partners. The claims against Grand Bank and the Company in this lawsuit have been settled and dismissed with prejudice. In May 2003 a purported class action complaint was filed against the Company. As amended, this suit alleges that Grand Bank breached escrow agreements and fiduciary duties and violated the Michigan Uniform Securities Act with respect to the investments secured by the purported class in viaticals and in interests in limited partnerships which made loans to Trade Partners secured by viaticals, and with respect to loans made by purported class members directly to Trade Partners. The Company has answered the complaint denying the material allegations and raising certain affirmative defenses. Management believes the Company has strong defenses and will vigorously defend the cases.

Trade Partners is now in receivership. The supervising court authorized the receiver to borrow money from Macatawa Bank to pay premiums, if needed. Macatawa Bank extended a $4 million line of credit to the receiver, conditioned upon obtaining a security interest in the viaticals. No draws were made against the line, and the line expired during the fourth quarter of 2004.

It is possible that one or more additional legal actions may be initiated involving the custodial and escrow agent services provided by Grand Bank in connection with Trade Partners. If any such legal actions are commenced, the Company intends to defend them vigorously. To the extent any pending or future claims allege errors or omissions on the part of Grand Bank or Macatawa Bank, management believes that some or all liability, if any is proven or established, will be covered by errors and omissions insurance maintained by Grand Bank and Macatawa Bank. The Company has reported the Trade Partners matter to its two insurance carriers. One carrier has assumed the Company’s defense and has advanced a portion of its defense costs pursuant to a reservation of rights letter asserting certain coverage defenses, and an Interim Funding Agreement. The other carrier has taken the position that the duty of defense rests solely with the first carrier, and reserves its rights with respect to indemnity.

The legal actions involving Trade Partners have not progressed to trial and the outcome of such actions is uncertain. While we are therefore unable to determine at this time whether or to what extent these actions may impact the Company, the Company believes it has strong defenses and fully intends to defend any and all such actions vigorously.

NOTE 9 – HEDGING ACTIVITIES

The Company’s asset/liability management policy includes guidelines for measuring and monitoring interest rate risk. Within these guidelines, parameters have been established for maximum fluctuations in net interest income. Possible fluctuations are measured and monitored using simulation analysis. The policies provide for the use of derivative instruments and hedging activities to aid in managing interest rate risk to within the policy parameters.

The Company’s assets are comprised of a large portion of loans on which the interest rates are variable. As such, the Company may periodically enter into derivative financial instruments to mitigate exposure to fluctuations in cash flows resulting from changes in interest rates. Interest rate swap arrangements may be utilized to hedge against these fluctuations in cash flows.

The Company has entered into interest rate swap arrangements (“swaps”), all of which are classified as cash flow hedges that convert the variable rate cash inflows on certain of its loans to fixed rates of interest. These swaps pay interest to the Company at a fixed rate and require interest payments from the Company at a variable rate. All of these swaps were fully effective during 2005 and the first three months of 2006. At March 31, 2006, it is anticipated that approximately $788,000, net of tax, of net unrealized losses on these cash flow hedges will be reclassified to earnings over the next twelve months.

Summary information about interest rate swaps were as follows (dollars in thousands).

NOTE 10 — REGULATORY MATTERS

The Company and the Bank 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 the 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 the Bank is only adequately capitalized, regulatory approval is required to accept brokered deposits; and if the Bank is undercapitalized, capital distributions are limited, as is asset growth and expansion, and plans for capital restoration are required.

At March 31, 2006 and December 31, 2005, actual capital levels and minimum required levels were (in thousands):

The Company and the Bank were categorized as well capitalized at March 31, 2006 and December 31, 2005. There are no conditions or events since March 31, 2006 that management believes have changed either institution’s category.

Macatawa Bank Corporation is a Michigan corporation and is the holding company for two wholly owned subsidiaries, Macatawa Bank and Macatawa Investment Services, Inc. and for two trusts, Macatawa Statutory Trust I and Macatawa Statutory Trust II. Macatawa Bank Corporation is a financial holding company pursuant to Title I of the Gramm-Leach-Bliley Act. Macatawa Bank is a Michigan chartered bank with depository accounts insured by the Federal Deposit Insurance Corporation. The bank operates twenty-three branch offices and a lending and operational service facility, providing a full range of commercial and consumer banking and trust services in Kent County, Ottawa County, and northern Allegan County, Michigan. Macatawa Investment Services is a broker/dealer that provides various services including discount brokerage and consultation regarding mutual funds and annuities. Macatawa Statutory Trusts I and II are grantor trusts and issued $20.0 million each of pooled trust preferred securities. These trusts are not consolidated in the Corporation’s financial statements. For further information regarding consolidation, see the Notes to the Consolidated Financial Statements included herein. Macatawa Bank Mortgage Company, a subsidiary of Macatawa Bank, originates and sells residential mortgage loans into the secondary market on a servicing released basis.

While maintaining asset quality and improving profitability, we have experienced rapid and substantial growth since opening Macatawa Bank in November of 1997. We first became profitable in 1999 and have increased earnings each year since then with 2005 net income reaching $20.9 million. Since our inception in 1997, we have raised approximately $100.6 million in capital through private and public common stock offerings and trust preferred offerings to facilitate our growth and progress over these years.

We believe that growth in core deposits is key to our long-term success and is our primary funding source for asset growth. Establishing a branching network in our markets has been of high importance in order to facilitate this core deposit growth. We have gained community awareness and acceptance in our markets through this expanding branch network and our high service quality standards.

The West Michigan markets within which we operate continue to provide significant expansion opportunities for us. We opened our tenth branch in the Kent County market on the north side of the greater Grand Rapids area during the second quarter of 2005. Because of the significance of the greater Grand Rapids market and the great opportunity for market share growth, we anticipate additional branch openings in this market. We also continue to enjoy success in building new and existing relationships in both our Holland/Zeeland and Grand Haven markets. We anticipate that we will continue to experience growth in our balance sheet and in our earnings due to these expansion opportunities.

RESULTS OF OPERATIONS

Summary: Net income for the quarter ended March 31, 2006 was $5.2 million, an increase of 15% as compared to first quarter 2005 net income of $4.5 million. Earnings per share on a diluted basis were $0.32 for the first quarter of 2006 compared to $0.28 for the same period in 2005.

The increase in net income was primarily due to an increase in total revenue, comprising net interest income and non-interest income of $2.0 million, partially offset by an increase in noninterest expense.

Net Interest Income: Net interest income totaled $16.3 million for the first quarter of 2006, an increase of $1.5 million or 10%, as compared to the first quarter of 2005. The improvement in net interest income was driven by a strong increase in average earning assets that was partially offset by a slight decline in the net interest margin. Average earning assets increased $175.4 million to $1.74 billion, or 11% for the first quarter of 2006 compared to the first quarter of 2005 of $1.57 billion. The net interest margin decreased 6 basis points to 3.78% for the first quarter of 2006 when compared to 3.84% for the first quarter of 2005.

The increase in the cost of funds exceeded the increase in the yield on earning assets and is the primary reason for the decrease in the net interest margin. For the first quarter of 2006, the yield on assets was 102 basis points higher than the first quarter of the prior year and the cost of funds was 121 basis points higher than the first quarter of the prior year. The increases in short-term rates that began in mid-2004 and have continued into 2006 have caused an increase in the yield on our variable rate loan portfolio and are the primary reasons for the increase in the yield on earning assets. An increase in the rates paid on our deposit accounts, the rollover of time deposits at higher rates within the current rising rate environment and a shift to higher costing sources of funds are the primary reasons for the increase in the cost of funds. The rates paid on time deposits have reached attractive levels causing deposit customers to shift funds from transaction accounts, primarily money market accounts, into the higher rate time accounts.

Anticipated growth in earning assets is expected to continue to increase levels of net interest income. We do not, however, expect future changes in short-term interest rates to have a significant impact on our net interest margin considering the Company’s move to a more balanced sensitivity to interest rate changes.

The following table shows an analysis of net interest margin for the three-month periods ending March 31, 2006 and 2005.
