Administrative Committee
First Merchants Corporation
  Retirement Savings Plan
Muncie, Indiana

We have audited the accompanying statements of net assets available for benefits
of First Merchants Corporation Retirement Savings Plan (Plan) as of December 31,
2004 and 2003, and the related statements of changes in net assets available for
benefits for the years ended December 31, 2004 and 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 (United States). 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, 2004 and 2003, and the changes in net assets available for benefits
for the years ended December 31, 2004 and 2003 in conformity with U. S.
generally accepted accounting principles.

The accompanying supplemental schedule 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. This supplemental schedule is the
responsibility of the Plan's management. The supplemental schedule has been
subjected to the auditing procedures applied in the audits of the basic
financial statements and, in our opinion, is fairly stated, in all material
respects, in relation to the basic financial statements taken as a whole.

                             Retirement Savings Plan
                          Notes to Financial Statements
                           December 31, 2004 and 2003

Note 1: Description of Plan

            The following description of First Merchants Corporation Retirement
            Savings Plan (Plan) provides only general information. Participants
            should refer to the Plan Document and Summary Plan Description for a
            more complete description of the Plan's provisions, which are
            available from the plan administrator.

      General

            The Plan is a defined-contribution plan sponsored by First Merchants
            Corporation (Corporation) for the benefit of all employees who are
            age 18 or older. It is subject to the provisions of the Employee
            Retirement Income Security Act of 1974 (ERISA). Merchants Trust
            Company is the trustee of the Plan. PrimeVest Financial Services is
            the custodian for a majority of the Plan's assets.

      Contributions

            The Plan permits eligible employees through a salary deferral
            election to have the Corporation make annual contributions of up to
            the limit allowed by the Internal Revenue Code. Employee rollover
            contributions are also permitted. The Corporation makes matching
            contributions of its employees' salary deferral amounts of 25% of
            the first 5% of employees' eligible compensation. Company
            profit-sharing contributions are discretionary as determined by the
            Company's Board of Directors. Contributions are subject to certain
            limitations.

            The Plan document also includes an automatic deferral feature
            whereby a participant is treated as electing to defer 3% of eligible
            compensation unless the participant made an affirmative election
            otherwise.

      Participant Investment Account Options

            Investment account options available include various funds including
            a Corporation common stock fund. Each participant has the option of
            directing his contributions into any of the separate investment
            accounts and may change the allocation daily.

      Participant Accounts

            Each participant's account is credited with the participant's
            contribution, the Corporation's contribution and plan earnings.
            Allocations of Plan earnings are based on participant account
            balances, as defined. The benefits to which a participant is
            entitled is the benefit that can be provided from the participant's
            vested account.


                                                                               4

      Vesting

            Participants are immediately vested in their voluntary contributions
            and rollover contribution accounts plus earnings thereon. Vesting in
            the Corporation's contribution portion of their accounts plus
            earnings thereon is based on years of continuous service. A
            participant is fully vested after five years of credited service.
            The nonvested balance is forfeited upon termination of service.
            Forefeitures are used to reduce the Corporation's contribution.

      Payment of Benefits

            Upon termination of service, participants may elect to receive a
            lump-sum amount or installments equal to the value of their
            accounts. Withdrawals other than for termination are permitted under
            circumstances provided by the Plan.

      Plan Termination

            Although it has not expressed any intent to do so, the Corporation
            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 will become 100%
            vested in their accounts.

Note 2: Summary of Significant Accounting Policies

      Method of Accounting

            The accompanying financial statements are prepared on the accrual
            method of accounting.

      Use of Estimates

            The preparation of financial statements in conformity with
            accounting principles generally accepted in the United States of
            America requires management to make estimates and assumptions that
            affect the reported amounts of net assets and changes in net assets
            available for benefits. Actual results could differ from those
            estimates.

      Valuation of Investments and Income Recognition

            Quoted market prices, if available, are used to value investments.
            The Federated Capital Preservation Fund is carried at contract
            value. Money market funds are valued at cost, which approximates
            market. Investment in the Corporation's unrestricted common stock is
            valued at the quoted market price.

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


                                                                               5

                           December 31, 2004 and 2003

      Plan Tax Status

            The Plan obtained its latest determination letter in September 2001,
            in which the Internal Revenue Service stated that the Plan and
            related trust, as then designed, were in compliance with the
            applicable requirements of the Internal Revenue Code and therefore
            not subject to tax. The Plan has been amended and restated since
            receiving the determination letter. However, the Plan administrator
            believes that the Plan and related trust are currently designed and
            being operated in compliance with the applicable requirements of the
            Internal Revenue Code.

      Payment of Benefits

            Benefit payments to participants are recorded upon distribution.

      Administrative Expenses

            Administrative expenses may be paid by the Corporation or the Plan,
            at the Corporation's discretion.

Note 3: Investments

            The Plan's investments are held by PrimeVest Financial Services,
            Inc. and the Corporation. The investment contract included in Plan
            assets may be subject to withdrawal charges upon contract
            termination. Crediting interest rates on the guaranteed interest
            portion of the investment contract are determined by the issuer. The
            Plan's investments (including investments bought, sold, and held
            during the year) appreciated in fair value as follows:

            Bank, First Merchants Insurance Services and Indiana Title Insurance
            Company to become participants in the Plan. Approximately
