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 generally accepted auditing standards. 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, 1999 and 1998, and the changes in net assets available for benefits for the year ended December 31, 1999 in conformity with generally accepted accounting principles. Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets held for investment purposes 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 financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements as a whole.

Participants should refer to the Plan agreement for a more complete description of the Plan's provisions. General: The Plan was established by the plan sponsor, Mercantile Bank of West Michigan (the Bank), effective January 1, 1998. The Bank acts as trustee for the Plan assets. The Plan is a defined contribution plan which covers all employees who have completed one hour of service. The Plan has a contributory 401(k) portion based on elective contributions from participants in the Plan. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). Contributions: Elective deferrals by participants under the 401(k) provisions are based on a percentage of their compensation as defined in the Plan agreement which are subject to certain limitations. Employees also may rollover account balances from other plans into their account. The Bank may, at the sole discretion of the Board of Directors, contribute to each participant's account a matching contribution which is a percentage of the participant's elective contribution for the year. For 1999, the Bank made matching contributions equal to 100% of the first 4% of the compensation deferred by each 401(k) participant subject to certain limitations as specified in the Plan agreement. Participant Accounts: Each participant's account is credited with the participant's contributions and allocation of (a) the Bank's contributions 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 aggregate of the participants' deferrals and rollovers and employer matching contributions. Investment options: Participants may direct, on a quarterly basis, the trustee to invest their elective 401(k) contributions as well as employer matching contributions to the Plan in any of the available investment options. Participants can individually determine their investment options based on desired level of risk and return for all contributions (employer and employee) to the Plan. Each participant has a self-directed account in addition to the investment options offered by the Plan. This gives participants the option to invest their contributions (employer and employee) to purchase common stock of Mercantile Bank Corporation or any other stock. As of December 31, 1999 and 1998, all Plan participants had opted to invest in Mercantile Bank Corporation common stock within their self-directed accounts. - -------------------------------------------------------------------------------- (Continued) 4. 6 MERCANTILE BANK OF WEST MICHIGAN 401(K) PLAN NOTES TO FINANCIAL STATEMENTS December 31, 1999 and 1998 - -------------------------------------------------------------------------------- NOTE 1 - DESCRIPTION OF PLAN (Continued) Retirement, Death and Disability: A participant is entitled to 100% of his or her account balance upon retirement, death or disability while employed. Vesting: Participants are immediately vested in their elective and employer contributions plus actual earnings thereon. Payment of Benefits: A participant or his or her beneficiary receives the vested portion in the participant's account in a lump sum. A participant may receive the portion of his or her account invested in Mercantile Bank Corporation in stock or cash. Loan Provisions: The Plan provides that participants can borrow funds against their account balances up to 50% of their vested account balance, or $50,000, whichever is less. Expenses: Substantially all administrative expenses are paid by the Plan sponsor. NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The principles and policies which significantly affect the determination of net assets and results of operations are summarized below. Investment Valuation and Income Recognition: Investments are stated at fair value. Mutual fund shares and Mercantile Bank Corporation common stock are traded on national exchanges and are valued at the last sales price on the date of valuation. 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 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. It is at least reasonably possible that a significant change may occur in the near term for the estimates of investment valuation. Payment of Benefits: Benefits are recorded when paid. New Accounting Standard: During 1999, the Plan adopted the requirements of the American Institute of Certified Public Accountants Statement of Position 99-3, Accounting and Reporting of Certain Defined Contribution Plan Investments and Other Disclosure Matters. The 1998 financial statement has been reclassified to be comparative. - -------------------------------------------------------------------------------- (Continued) 5. 7 MERCANTILE BANK OF WEST MICHIGAN 401(K) PLAN NOTES TO FINANCIAL STATEMENTS December 31, 1999 and 1998 - -------------------------------------------------------------------------------- NOTE 3 - 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 and its related regulations.
