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. We were not engaged to perform an audit of the Plan's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and 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 then ended, 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 schedule of assets (held at end of year) as of December 31, 2004 is presented for the purpose of additional analysis and is not a required part of the 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. /s/ Ernst & Young LLP Chicago, Illinois June 27, 2005 1 TRUSTCORP MORTGAGE COMPANY EMPLOYEE RETIREMENT SAVINGS PLAN STATEMENTS OF NET ASSETS AVAILABLE FOR BENEFITS December 31 2004 2003 -------------------------------- Assets Cash and cash equivalents $ 75,609 $ 45,683 Investments at fair value Common stock 848,443 923,402 Mutual funds 3,676,785 2,961,002 1st Source Bank common trust fund 377,301 511,452 Participant loans receivable 198,250 217,024 -------------------------------- Total investments 5,100,779 4,612,880 Contribution receivable Employer 36,349 24,151 Employee 17,031 15,332 -------------------------------- 53,380 39,483 Other assets Other receivables 5,789 6,374 -------------------------------- Total assets 5,235,557 4,704,420 Liabilities Accrued expenses payable 10,757 10,806 -------------------------------- Total liabilities 10,757 10,806 -------------------------------- Net assets available for benefits $ 5,224,800 $ 4,693,614 ================================ See accompanying notes. 2 TRUSTCORP MORTGAGE COMPANY EMPLOYEE RETIREMENT SAVINGS PLAN STATEMENT OF CHANGES IN NET ASSETS AVAILABLE FOR BENEFITS For the Years Ended December 31 2004 2003 ----------------------------- Additions Investment income: Interest $ 17,327 $ 16,471 Dividends 58,661 49,425 ----------------------------- 75,988 65,896 Contributions: Employer 157,885 174,768 Employee 330,607 453,176 ----------------------------- 488,492 627,944 Net realized and unrealized appreciation in fair value of investments: 427,212 764,409 ----------------------------- Total additions 991,692 1,458,249 Deductions Benefits paid to participants 432,316 113,361 Plan expenses 28,190 25,122 ----------------------------- Total deductions 460,506 138,483 ----------------------------- Net increase 531,186 1,319,766 Net assets available for benefits: Beginning of year 4,693,614 3,373,848 ----------------------------- End of year $ 5,224,800 $4,693,614 ============================= See accompanying notes. 3 Trustcorp Mortgage Company Employee Retirement Savings Plan Notes to Financial Statements December 31, 2004 1. DESCRIPTION OF THE PLAN GENERAL The Trustcorp Mortgage Company Employee Retirement Savings Plan (the Plan) is a defined contribution plan covering substantially all employees of Trustcorp Mortgage Company (Trustcorp) 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). Trustcorp is a wholly owned subsidiary of 1st Source Corporation. The Board of Directors of Trustcorp Mortgage Company may authorize a contribution from consolidated net profit or retained earnings in excess of the 401(k) matching contributions which are also approved by the Board. These discretionary contributions are made in cash and are allocated to each participant based upon provisions of the Plan Agreement. FUNDING AND VESTING Participants are permitted to designate up to 25% of their annual compensation as a salary reduction contribution to the Plan under Section 401(k) of the Internal Revenue Code. In addition, participants age 50 or older may elect to defer up to an additional $3,000 (in 2004) and $2,000 (in 2003) per year (called "catch-up contributions") to the plan. When applying the discretionary matching contributions, only salary reductions up to six percent (6%) of eligible employee compensation is considered. For the years 2004 and 2003, the discretionary matching contribution percentage was 50%. In addition, as part of the profit sharing component of the Plan, Trustcorp has the discretion to make an additional contribution to the Plan, out of current or accumulated net profits. There was no discretionary contribution to the Plan for 2004 and the discretionary contribution for 2003 was $16,000. Vesting of participant contributions and Trustcorp's 401(k) matching contributions are immediate. Vesting of the Trustcorp contributions for the profit sharing component of the Plan is based on years of credited service, with participants becoming 100% vested after seven years of credited service. However, a participant becomes 100% vested upon satisfying the requirements for early retirement under the terms of the Plan document. Each participant's account is credited with the participant's contribution and an allocation of (a) Trustcorp's contribution, (b) Plan earnings net of Plan expenses, and (c) forfeitures of terminated participants' non-vested 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. 4 Trustcorp Mortgage Company Employee Retirement Savings Plan Notes to Financial Statements December 31, 2004 1. DESCRIPTION OF THE PLAN (CONTINUED) 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 the national prime rate as posted in the Wall Street Journal. 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 be up to fifteen years. PAYMENT OF BENEFITS On termination of service, a participant receives a lump-sum amount equal to the value of his or her vested account balance. At December 31, 2004 and 2003, there have been no amounts 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, Trustcorp 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, the Summary Plan Description, or the Employee Handbook for a more complete description of the Plan's provisions. Copies are available from the Trustcorp Human Resources Division. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES INVESTMENT VALUATION AND INCOME RECOGNITION Investments are stated at fair value. Securities traded on a national securities exchange are valued at the last reported sales price on the last business day 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 5 Trustcorp Mortgage Company Employee Retirement Savings Plan Notes to Financial Statements December 31, 2004 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) INVESTMENT VALUATION AND INCOME RECOGNITION (CONTINUED) net asset value as reported by the funds. Loans to participants 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 preparation of financial statements in conformity with United States generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. 3. INVESTMENTS During 2004 and 2003, the Plan's investments (including investments purchased, sold, as well as held during the year) appreciated in value by $427,212 and $764,409, respectively, as follows: Net Appreciation (Depreciation) in Fair Value During 2004 2003 ------------------- -------------------- Common stock $124,479 $205,600 Mutual funds 290,895 539,009 1st Source Bank common trust fund 11,838 19,800 ------------------- -------------------- $427,212 $764,409 =================== ==================== 6 Trustcorp Mortgage Company Employee Retirement Savings Plan Notes to Financial Statements December 31, 2004 3.

Recordkeeper & Tax Accountant $18,839 $16,701 1st Source Bank Trustee 9,351 8,421 --------- -------- $28,190 $25,122 ========= ======== 5. INCOME TAX STATUS The Plan has received a determination letter from the Internal Revenue Service dated September 30, 2003, stating that the Plan is qualified under Section 401(a) of the Internal Revenue Code (the Code) and, therefore, the related trust is exempt from taxation. Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualification. The Plan Administrator believes the Plan is being operated in compliance with the applicable requirements of the Code and, therefore, believes that the Plan is qualified and the related trust is tax exempt. 6. RISKS AND UNCERTAINTIES The Plan invests in various investment securities. 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, it is likely that changes in the values of investment securities will occur in the near term and that such changes could materially affect participants' account balances and the amounts reported in the statements of assets available for benefits. 8 Trustcorp Mortgage Company Employee Retirement Savings Plan Schedule H, Line 4i - Schedule of Assets (Held at End of Year) December 31, 2004 EIN: 35-1933290 Plan Number: 003 Identity of Issue, Borrower, Lessor or Similar Party Description of Investment Cost Fair Value ----------------------------------------------------------------------------------------------------------------------- Common Stock: * 1st Source Corporation 26,741 shares ** $ 682,164 Key Corp 4,905 shares ** 166,279 -------------- 848,443 Mutual Funds: Morgan Stanley Institutional International Equity Fund 48,771 units ** 1,016,874 * 1st Source Monogram Income Equity Fund 54,969 units ** 738,785 * 1st Source Monogram Diversified Equity Fund 100,037 units ** 736,269 * 1st Source Monogram Special Equity Fund 45,793 units ** 397,025 * 1st Source Monogram Long/Short Fund 34,760 units ** 375,063 * 1st Source Monogram Income Fund 41,112 units ** 412,769 -------------- 3,676,785 Common Trust Funds: * 1st Source Bank Employee Benefits 15,121 units ** 377,301 -------------- Guaranteed Income Fund 377,301 * Loans to Participants: $198,250 principal amount, interest rates ranging from 5.00% to 10.50%, maturities through 2012 ** 198,250 -------------- 198,250 $ 5,100,779 ============== * Indicates a party-in-interest to the Plan. **Historical cost information is not required for participant-directed investments. 9
