             Report of Independent Registered Public Accounting Firm


Human Resources Committee of the Board of Directors
1st Source Corporation

We have audited the accompanying statements of net assets available for benefits
of the 1st Source Corporation Employees' Profit Sharing Plan and Trust 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 (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, 2003 and 2002, and the changes in its net assets available for
benefits for the year ended December 31, 2003, in conformity with U.S. generally
accepted accounting principles.

Our audits were performed for the purpose of forming an opinion on the financial
statements taken as a whole. The accompanying supplemental schedule of assets
held for investment purposes at end of year as of December 31, 2003, is
presented for purposes 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 our audits of the financial
statements and, in our opinion, is fairly stated in all material respects in
relation to the financial statements taken as a whole.

1. DESCRIPTION OF THE PLAN

GENERAL

The 1st Source Corporation Employees' Profit Sharing Plan and Trust (the "Plan")
is a defined contribution plan covering substantially all employees of 1st
Source Corporation and its subsidiaries, with the exception of Trustcorp
Mortgage Company, ("1st Source") who have completed one year of service in which
the employee has worked 1,000 hours. The Plan is subject to the provisions of
the Employee Retirement Income Security Act of 1974 ("ERISA").

CONTRIBUTIONS AND VESTING

Effective July 1, 2002 participants are permitted to designate up to 25% of
their annual pre-tax compensation as a salary reduction contribution to the Plan
(prior to that date participants were permitted to designate up to 15%).
Provided net profits or retained earnings are sufficient, 1st Source will match
employee salary reduction contributions one hundred percent (100%) for the first
four percent (4%) of compensation that is deferred and fifty percent (50%) of
any additional contributions up to six percent (6%) of compensation that is
deferred. Participants direct the investment of their contributions into various
investment options offered by the Plan. The Plan currently offers nine different
fund options, one of which is the 1st Source Stock Fund, which primarily
consists of 1st Source Corporation common stock. 1st Source matching
contributions are invested in the 1st Source Stock Fund.

1st Source makes an annual, mandatory contribution to the plan based on 2%
of participants' eligible annual compensation. This contribution is made to the
Profit Sharing Mandatory Account of the Plan. The Profit Sharing Mandatory
Account is invested in a diversified portfolio of investments as directed by 1st
Source.

In addition, the Human Resources Committee of the Board of Directors of 1st
Source Corporation may authorize a contribution from consolidated net profits or
retained earnings in excess of the minimum 401(k) matching contributions
required by the Plan. This discretionary profit sharing contribution is made to
the Profit Sharing Regular Account of the Plan. The Profit Sharing Regular
Account is invested in a diversified portfolio of investments as directed by 1st
Source. There was no discretionary contribution for 2003.

Vesting of participant contributions is immediate upon contribution to the Plan.
Vesting of 1st Source contributions, both of the match of the employee salary
reduction contributions, the discretionary profit sharing contribution and the
mandatory 2% contribution, is based on years of credited service. A participant
is one hundred percent (100%) vested after five years of credited service or
upon reaching early retirement age, normal retirement age, or disability.

                    Notes to Financial Statements (Continued)

1. DESCRIPTION OF THE PLAN (CONTINUED)

CONTRIBUTIONS AND VESTING (CONTINUED)

Each participant's account is credited with the participant's contribution and
an allocation of (a) 1st Source's contribution, (b) Plan earnings, and (c)
forfeitures of terminated participants' nonvested accounts. Allocations are
based on participant compensation 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 balance.

PARTICIPANT LOANS

Participants may borrow from the Plan amounts not to exceed the lesser of
one-half of the participant's vested account balance or $50,000. The loans are
collateralized by the participant's vested account balance and bear interest at
fixed rates of 1% above 1st Source Bank's (a wholly owned subsidiary of 1st
Source Corporation) prime rate. The loans are repayable over five years except
for loans used to acquire or construct a participant's principal residence in
which case the repayment term may exceed five years.

PAYMENT OF BENEFITS

On termination of service, a participant may elect to receive either a lump-sum
amount equal to the value of his or her vested account balance or periodic
installments in accordance with Plan provisions. At December 31, 2003 and 2002,
$1,748,546 and $1,056,932, respectively, of the net assets available for
benefits at the end of the year has been allocated to participants who had
effectively withdrawn from the Plan and requested distribution as of the end of
those respective years, but had yet to receive their final distribution.

PLAN TERMINATION

Although it has not expressed any intention to do so, 1st Source 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 fully vested in their accounts.

The foregoing description of the Plan provides only general information.
Participants should refer to the Plan Agreement for a more complete description
of the Plan's provisions. Copies are available from the 1st Source Corporation
Human Resources Division.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

INVESTMENT VALUATION

Investments are stated at fair value. Securities traded on a national securities
exchange are valued at the average of the reported sales prices for the last
five business days of the plan year; securities traded in the over-the-counter
market and listed securities for which no sale was reported on that date are
valued at the average of the last reported bid and ask prices. The fair value of
mutual funds and the Plan's participation in common/collective trust funds of
1st Source Bank are stated at the net asset value as reported by the funds on
the last business day of the plan year. Loans to participants and short-term
temporary investments are stated 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.

USE OF ESTIMATES

The financial statements of the Plan are presented on the accrual basis and are
prepared in conformity with accounting principles generally accepted in the
United States, which require management to make estimates and assumptions that
affect amounts in the financial statements and accompanying notes. Actual
results could differ from those estimates.

CASH EQUIVALENTS

All short-term investments with a maturity of less than 90 days are deemed to be
cash equivalents.

RECLASSIFICATIONS

Certain reclassifications have been made to the prior year financial statements
to conform with the current year presentation.
