REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Plan Administrator
Macatawa Bank 401(k) Plan
Holland, Michigan

We have audited the accompanying statements of net assets available for benefits of the Macatawa Bank 401(k) Plan (“the Plan”) as of December 31, 2003 and 2002, and the related statement of changes in net assets available for benefits for the year ended December 31, 2003. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2003 and 2002, and the changes in net assets available for benefits for the year ended December 31, 2003 in conformity with U.S. generally accepted accounting principles.

Our audit was conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets (held at end of year) is presented for the purpose of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The supplemental schedule has been subjected to the auditing procedures applied in the audit of the basic 2003 financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic 2003 financial statements as a whole.

NOTE 1 — DESCRIPTION OF PLAN

The following description of the Macatawa Bank (Bank) 401(k) Plan (Plan) provides only general information. Participants should refer to the Plan agreement or Summary Plan Description for a more complete description of the Plan’s provisions. The Bank is a 100% owned subsidiary of Macatawa Bank Corporation.

General: The Plan is a defined contribution plan covering all full-time employees who have attained the age of 21 or older. The Plan is subject to the provisions of the Employee Retirement Income Security Act (ERISA).

Contributions: Each year, participants may contribute up to 15 percent of pretax annual compensation, as defined by the Plan. Participants may also contribute amounts representing distributions from other qualified defined benefit or defined contribution plans. Participants direct the investment of their contributions into various investment options offered by the Plan. The Bank contributes an amount equal to 100 percent of the first 3 percent and 50 percent of the second 3 percent of base compensation that a participant contributes to the Plan. All administrative costs have been paid by the Bank. During 2003 Macatawa Bank Corporation common stock was added as an investment option to the Plan.

Participant Accounts: Each participant’s account is credited with the participant’s contribution and an allocation of (a) the Bank’s contribution, if eligible, and b) Plan earnings. Allocations are based on participant earnings or account balances, as defined. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested account. Each participant directs the investment of their account to any of the investment options available under the Plan.

Vesting: A participant is immediately vested in employee and employer matching contributions plus actual earnings thereon.

Payment of Benefits: On termination of service due to death, disability or retirement, a participant may elect to receive an amount equal to the value of the participant’s vested interest in his or her account in either a lump-sum amount, or in annual payments, or more frequently if permitted by the Administrator, over an elected period of years not exceeding the life expectancy of the participant or the joint life expectancy of the participant and a beneficiary. For termination of service due to other reasons, a participant may transfer the value of the vested interest in his or her account to the trustee or custodian of another qualified retirement plan or receive a lump-sum distribution.

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Accounting: The financial statements of the Plan are prepared under the accrual method of accounting.

Investment Valuation and Income Recognition: The Plan’s investments are stated at fair value other than money market fund investments and participant loans. Quoted market prices are used to value investments. Shares of registered investment companies are valued at the net asset value of shares held by the Plan at year-end. Money market fund investments and participant loans are reported at cost which approximates fair value.

Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date.

Estimates: The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires the plan administrator to make estimates and assumptions that affect certain reported amounts and disclosures, and actual results may differ from these estimates. Investment valuation estimates are particularly subject to change in the near term.

Risks and Uncertainties: The Plan provides for investment options in various mutual funds, money market funds, and Macatawa Bank Corporation common stock. The underlying investment securities are exposed to various risks, such as, interest rate, market and credit risks. Due to the level of risk associated with certain investment securities and the level of uncertainty related to changes in the value of investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect the amounts reported in the statement of net assets available for benefits and participants’ individual account balances.

Payments of Benefits: Benefits are recorded when paid.

NOTE 3 – RIGHTS UPON PLAN TERMINATION

Although it has not expressed any intent to do so, the Bank has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of plan termination, participants would become 100% vested in their accounts.

NOTE 5 — PARTY-IN-INTEREST TRANSACTIONS

Parties-in-interest are defined under Department of Labor (DOL) regulations as any fiduciary of the Plan, any party rendering service to the Plan, the employer, and certain others. The Plan’s investment in participant loans as of December 31, 2003 and 2002 represent party-in-interest investments. Participant loans totaled $10,682 and $14,160 as of December 31, 2003 and 2002.

Macatawa Bank, through its trust department, serves as trustee, custodian and recordkeeper for the Plan. Therefore, all transactions between the Plan and Macatawa Bank constitute party-in-interest transactions.
