                             1ST SOURCE CORPORATION
                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

Note 1.    Basis of Presentation

     The accompanying unaudited consolidated financial statements reflect all
adjustments (all of which are normal and recurring in nature) which are, in the
opinion of management, necessary for a fair presentation of the consolidated
financial position, the results of operations, changes in shareholders' equity,
and cash flows for the periods presented. These unaudited consolidated financial
statements have been prepared according to the rules and regulations of the
Securities and Exchange Commission (SEC) and, therefore, certain information and
footnote disclosures normally included in financial statements prepared in
accordance with U. S. generally accepted accounting principles have been
omitted. The Notes to the Consolidated Financial Statements appearing in 1st
Source Corporation's Annual Report on Form 10-K (2005 Annual Report), which
include descriptions of significant accounting policies, should be read in
conjunction with these interim financial statements. The balance sheet at
December 31, 2005 has been derived from the audited financial statements at that
date but does not include all of the information and footnotes required by U. S.
generally accepted accounting principles for complete financial statements.
Certain amounts in the prior period consolidated financial statements have been
reclassified to conform with the current year presentation.

Note 2.    Recent Accounting Pronouncements

     SHARE-BASED PAYMENT: Effective January 1, 2006, we adopted the fair value
recognition provisions of Statement of Financial Accounting Standards (SFAS) No.
123 (revised 2004), "Share-Based Payment" (SFAS No.123(R)), using the modified
prospective transition method and, therefore, have not restated results for
prior periods. Under this transition method, stock-based compensation expense
for the first quarter of 2006 included compensation expense for all stock-based
compensation awards granted prior to, but not yet vested as of January 1, 2006,
based on the grant date fair value estimated in accordance with the original
provision of SFAS No. 123, "Accounting for Stock-Based Compensation" ("SFAS
No.123"). Stock-based compensation expense for all stock-based compensation
awards granted after January 1, 2006 is based on the grant-date fair value
estimated in accordance with the provisions of SFAS No.123(R). We recognize
these compensation costs on a straight-line basis over the requisite service
period of the award. Prior to the January 1, 2006 adoption of SFAS No.123(R), we
recognized stock-based compensation expense in accordance with Accounting
Principles Board (APB) Opinion No. 25, "Accounting for Stock Issued to
Employees" (APB No. 25). In March 2005, the Securities and Exchange Commission
(the SEC) issued Staff Accounting Bulletin No. 107 (SAB No. 107) regarding the
SEC's interpretation of SFAS No.123(R) and the valuation of share-based payments
for public companies. We have applied the provisions of SAB No. 107 in its
adoption of SFAS No. 123(R). See Note 5 to the Unaudited Consolidated Financial
Statements for a further discussion on stock-based compensation.

     ACCOUNTING FOR SERVICING OF FINANCIAL ASSETS: In March 2006, the Financial
Accounting Standards Board (FASB) issued SFAS No. 156, "Accounting for Servicing
of Financial Assets- an amendment of FASB Statement No. 140." SFAS No.156
requires an entity to recognize a servicing asset or servicing liability each
time it undertakes an obligation to service a financial asset by entering into a
servicing contract in specific situations. Additionally, the servicing asset or
servicing liability shall be initially measured at fair value; however, an


                                       7



entity may elect the "amortization method" or "fair value method" for subsequent
balance sheet reporting periods. SFAS No.156 is effective as of an entity's
first fiscal year beginning after September 15, 2006. Early adoption is
permitted as of the beginning of an entity's fiscal year, provided the entity
has not yet issued financial statements, including interim financial statements,
for any period of that fiscal year. We do not expect the adoption of this
statement to have a material impact on our financial condition, results of
operations or cash flows.

    ACCOUNTING FOR CERTAIN HYBRID FINANCIAL INSTRUMENTS: In February 2006, the
FASB issued SFAS No. 155, "Accounting for Certain Hybrid Financial Instruments -
an amendment of FASB Statements No. 133 and 140." SFAS No. 155 simplifies
accounting for certain hybrid instruments currently governed by SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities," by allowing fair
value remeasurement of hybrid instruments that contain an embedded derivative
that otherwise would require bifurcation. SFAS No. 155 also eliminates the
guidance in SFAS No.133 Implementation Issue No. D1, "Application of Statement
133 to Beneficial Interests in Securitized Financial Assets," which provides
such beneficial interests are not subject to SFAS No.133. SFAS No. 155 amends
SFAS No. 140, "Accounting for Transfers and Servicing of Financial Assets and
Extinguishments of Liabilities - a Replacement of FASB Statement No. 125," by
eliminating the restriction on passive derivative instruments that a qualifying
special-purpose entity may hold. This statement is effective for financial
instruments acquired or issued after the beginning of our fiscal year 2007. We
do not expect the adoption of this statement to have a material impact on our
financial condition, results of operations or cash flows.

     MEANING OF OTHER-THAN-TEMPORARY IMPAIRMENT: In November 2005, the Financial
Accounting Standards Board (FASB) issued Staff Position (FSP) SFAS No. 115-1 and
124-1, "The Meaning of Other-Than-Temporary Impairment and Its Application to
Certain Investments." The FSP addresses the determination of when an investment
is considered impaired, whether that impairment is other-than-temporary, and the
measurement of an impairment loss. The FSP also includes accounting
considerations subsequent to the recognition of an other-than-temporary
impairment and requires certain disclosures about unrealized losses that have
not been recognized as other-than-temporary impairments. The FSP amends SFAS No.
115, "Accounting for Certain Investments in Debt and Equity Securities," and
SFAS No. 124, "Accounting for Certain Investments Held by Not-for-Profit
Organizations," and APB Opinion No. 18, "The Equity Method of Accounting for
Investments in Common Stock." The FSP nullifies certain requirements of EITF
Issue No. 03-1, "The Meaning of Other-Than-Temporary Impairment and its
Application to Certain Investments," and supersedes Emerging Issues Task Force
(EITF) Abstracts, Topic D-44, "Recognition of Other-Than-Temporary Impairment
upon the Planned Sale of a Security Whose Cost Exceeds Fair Value." The FSP was
required to be applied to reporting periods beginning after December 15, 2005.
The issuance of this FSP did not have a material impact on the financial
condition, the results of operations, or liquidity of 1st Source.

     ACCOUNTING CHANGES AND ERROR CORRECTIONS: In May 2005, the FASB issued SFAS
No. 154, "Accounting for Changes and Error Corrections," which changes the
accounting for and reporting of a change in accounting principle. This statement
also applies to all voluntary changes in accounting principle and changes
required by an accounting pronouncement in the unusual instance that the
pronouncement does not include specific transition provisions. This statement
requires retrospective application to prior period financial statements of
changes in accounting principle, unless it is impractical to determine either
the period - specific or cumulative effects of the change. SFAS No. 154 was
effective for accounting changes made in fiscal years beginning after December
15, 2005. The adoption of this standard did not have a material effect on the
financial condition, the results of operations or liquidity of 1st Source.

Note 3.  Reserve for Loan and Lease Losses

     The reserve for loan and lease losses is maintained at a level  believed to
be adequate by management  to absorb  probable  losses  inherent in the loan and
lease portfolio.  The determination of the reserve requires significant judgment
reflecting  management's best estimate of probable loan and lease losses related
to  specifically  identified  loans and leases as well as probable losses in the
remainder  of the  various  loan  and  lease  portfolios.  The  methodology  for
assessing the  appropriateness  of the reserve consists of several key elements,
which include:  specific  reserves for identified  special  attention  loans and
leases (classified loans and leases and internal watch list credits), percentage
allocations for special  attention loans and leases without  specific  reserves,
formula  reserves for each  business  lending  division  portfolio,  including a
higher  percentage  reserve  allocation for special  attention  loans and leases
without a  specific  reserve,  and  reserves  for pooled  homogeneous  loans and
leases.  Management's  evaluation  is based  upon a  continuing  review of these
portfolios,  estimates of future  customer  performance,  collateral  values and
dispositions  and forecasts of future economic and geopolitical  events,  all of
which are subject to judgment and will change.

Note 4.  Financial Instruments with Off-Balance-Sheet Risk

     To meet the financing needs of our customers, 1st Source Corporation and
its subsidiaries are parties to financial instruments with off-balance-sheet
risk in the normal course of business. These off-balance-sheet financial
instruments include commitments to originate, purchase and sell loans and
standby letters of credit. The instruments involve, to varying degrees, elements
of credit and interest rate risk in excess of the amount recognized in the
consolidated statements of financial condition. Our exposure to credit loss in
the event of nonperformance by the other party to the financial instruments for
loan commitments and standby letters of credit is represented by the dollar
amount of those instruments. We use the same credit policies and collateral
requirements in making commitments and conditional obligations as we do for
on-balance-sheet instruments.

     Trustcorp Mortgage Company and 1st Source Bank (Bank), subsidiaries of 1st
Source Corporation, grant mortgage loan commitments to borrowers, subject to
normal loan underwriting standards. The interest rate risk associated with these
loan commitments is managed by entering into contracts for future deliveries of
loans. Loan commitments generally have fixed expiration dates or other
termination clauses and may require payment of a fee. Since many of the
commitments are expected to expire without being drawn upon, the total
commitment amounts do not necessarily represent future cash requirements.

     We issue letters of credit which are conditional commitments that guarantee
the performance of a customer to a third party. The credit risk involved and
collateral obtained in issuing letters of credit is essentially the same as that
involved in extending loan commitments to customers.

     As of March 31, 2006 and December 31, 2005, 1st Source had commitments
outstanding to originate and purchase mortgage loans aggregating $210.24 million
and $130.73 million, respectively. Outstanding commitments to sell mortgage
loans aggregated $114.76 million at March 31, 2006, and $98.39 million at
December 31, 2005. Standby letters of credit totaled $75.86 million and $76.43
million at March 31, 2006, and December 31, 2005, respectively. Standby letters
of credit have terms ranging from six months to one year.


                                       9



Note 5.  Stock-Based Compensation

     As of March 31, 2006, we had five stock-based employee compensation plans,
which are more fully described in Note K of the Consolidated Financial
Statements in 1st Source's Annual Report on Form 10-K for the year ended
December 31, 2005. These plans include two stock option plans, the Employee
Stock Purchase Plan, the Executive Incentive Plan, and the Restricted Stock
Award Plan. The Employee Stock Purchase Plan is non-compensatory.

     Effective January 1, 2006, we adopted the fair value recognition provisions
of SFAS No. 123(R), using the modified prospective transition method and,
therefore, have not restated results for prior periods. Under this transition
method, stock-based compensation expense for the first quarter of 2006 included
compensation expense for all stock-based compensation awards granted prior to,
but that remained unvested as of, January 1, 2006. Compensation expense was
based on the grant date fair value estimated in accordance with the original
provision of SFAS No. 123.

     Prior to January 1, 2006, we accounted for stock-based compensation under
the recognition, measurement and pro forma disclosure provisions of APB No. 25,
the original provisions of SFAS No. 123, and SFAS No. 148, "Accounting for
Stock-Based Compensation-Transition and Disclosure" (SFAS 148). In accordance
with APB No. 25, we generally would have recognized compensation expense for
stock awards on the grant date and we generally would have recognized
compensation expense for stock options only when we granted options with a
discounted exercise price or modified the terms of previously issued options,
and would have recognized the related compensation expense ratably over the
associated service period, which was generally the option vesting term.

       Stock-based compensation expense for all stock-based compensation awards
granted after January 1, 2006, is based on the grant-date fair value. For all
awards except stock option awards, the grant date fair value is either the fair
market value per share or book value per share (corresponding to the type of
stock awarded) as of the grant date. For stock option awards, the grant date
fair value is estimated using the Black-Scholes option pricing model. For all
awards we recognize these compensation costs only for those shares expected to
vest on a straight-line basis over the requisite service period of the award,
for which we use the related vesting term. We estimate forfeiture rates based on
historical employee option exercise and employee termination experience. We have
identified separate groups of awardees that exhibit similar option exercise
behavior and employee termination experience and have considered them as
separate groups in the valuation models and expense estimates.

       As a result of our January 1, 2006, adoption of SFAS No.123(R), the
impact to the Consolidated Financial Statements for the three months ended March
31, 2006 on income before income taxes and on net income were additions of $1.15
million and $0.71 million, respectively. The cumulative effect of the change in
accounting was $0.66 million before income taxes and $0.40 million, after income
taxes. The impact on both basic and diluted earnings per share for the three
months ended March 31, 2006 was $0.02 per share. In addition, prior to the
adoption of SFAS No. 123(R), we presented the tax benefit of stock option
exercises as operating cash flows. Upon the adoption of SFAS No. 123(R), tax
benefits resulting from tax deductions in excess of the compensation cost
recognized for those options are classified as financing cash flows.

PRO FORMA INFORMATION UNDER SFAS NO. 123

       Pro forma information regarding the effect on the net income and basic

       The stock-based compensation expense recognized in the condensed
consolidated statement of operations for the three months ended March 31, 2006
is based on awards ultimately expected to vest, and accordingly has been
adjusted by the amount of estimated forfeitures. SFAS No. 123(R) requires
forfeitures to be estimated at the time of grant and revised, if necessary, in
subsequent periods if actual forfeitures differ from those estimates.
Forfeitures were estimated based partially on historical experience.

       The aggregate intrinsic value in the table below represents the total
pretax intrinsic value (the difference between 1st Source's closing stock price
on the last trading day of the first quarter of 2006 (March 31, 2006) and the
exercise price, multiplied by the number of in-the-money options) that would
have been received by the option holders had all option holders exercised their
options on March 31, 2006, this amount changes based on the fair market value of
1st Source's stock. Total intrinsic value of options exercised for the three
months ended March 31, 2006 was $342 thousand. Total fair value of options
vested and expensed was $12 thousand, net of tax, for the three months ended
March 31, 2006. No options were granted during the three months ended March 31,
2006 or 2005.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     Except for historical information contained herein, the matters discussed
in this document express "forward-looking statements." Generally, the words
"believe," "expect," "intend," "estimate," "anticipate," "project," "will,"
"should," and similar expressions indicate forward-looking statements. Those

uncertainties. We caution readers not to place undue reliance on any
forward-looking statements, which speak only as of the date made. We may make
other written or oral forward-looking statements from time to time. Readers are


                                       12



advised that various important factors could cause our actual results or
circumstances for future periods to differ materially from those anticipated or
projected in such forward-looking statements. Such factors include, but are not
limited to, changes in law, regulations or U. S. generally accepted accounting
principles; our competitive position within the markets we serve; increasing
consolidation within the banking industry; unforeseen changes in interest rates;
unforeseen changes in loan prepayment assumptions; unforeseen downturns in or
major events affecting the local, regional or national economies or the
industries in which we have credit concentrations; and other matters discussed
in our filings with the SEC, including our Annual Report on Form 10-K for 2005,
which filings are available from the SEC. We undertake no obligation to publicly
update or revise any forward-looking statements.

     The following management's discussion and analysis is presented to provide
information concerning our financial condition as of March 31, 2006, as compared
to December 31, 2005, and the results of operations for the three months ended
March 31, 2006 and 2005. This discussion and analysis should be read in
conjunction with our consolidated financial statements and the financial and
statistical data appearing elsewhere in this report and our 2005 Annual Report.


                               FINANCIAL CONDITION
                               -------------------

    Our total assets at March 31, 2006, were $3.46 billion, down 1.46% from
December 31, 2005. Total loans and leases increased slightly and total deposits
decreased 2.45% over the comparable figures at the end of 2005.

     Nonperforming assets at March 31, 2006, were $21.07 million, a slight
improvement over the $22.04 million reported at December 31, 2005. Nonperforming
assets decreased primarily due to a decrease in aircraft and construction
equipment nonaccrual loans. At March 31, 2006, nonperforming assets were 0.83%
of net loans and leases compared to 0.87% at December 31, 2005.

Accrued income and other assets were as follows:

                                     -------

      As of March 31, 2006, total shareholders' equity was $347.35 million, up
marginally from the $345.58 million at December 31, 2005. In addition to net
income of $9.93 million, other significant changes in shareholders' equity
during the first three months of 2006 included $5.86 million in treasury stock
purchases, and $2.89 million of dividends paid. The accumulated other
comprehensive loss component of shareholders' equity totaled $3.05 million at
March 31, 2006, compared to $3.24 million at December 31, 2005. The improvement


                                       13



in accumulated other comprehensive loss for the first quarter of 2006 over the
same period of 2005 was primarily a result of changes in unrealized gain/loss on
securities in the available-for-sale portfolio. Our equity-to-assets ratio was
10.04% as of March 31, 2006, compared to 9.84% at December 31, 2005. Book value
per common share rose to $16.96 at March 31, 2006, up from $16.72 at December
31, 2005.

      We declared and paid dividends per common share of $0.14 during the first
quarter of 2006. The trailing four quarters dividend payout ratio, representing
dividends per share divided by diluted earnings per share, was 29.14%. The
dividend payout is continually reviewed by management and the Board of
Directors.

      The banking regulators have established guidelines for leverage capital
requirements, expressed in terms of Tier 1 or core capital as a percentage of
average assets, to measure the soundness of a financial institution. In
addition, banking regulators have established risk-based capital guidelines for
U.S. banking organizations. The actual capital amounts and ratios of 1st Source
and our largest subsidiary, the Bank, as of March 31, 2006, are presented in the

                     LIQUIDITY AND INTEREST RATE SENSITIVITY
                     ---------------------------------------

     The Bank's liquidity is monitored and closely managed by the
Asset/Liability Committee (ALCO), which is comprised of the Bank's senior
management. Asset and liability management includes the management of interest
rate sensitivity and the maintenance of an adequate liquidity position. The
purpose of interest rate sensitivity management is to stabilize net interest
income during periods of changing interest rates.

     Liquidity management is the process by which the Bank ensures that adequate
liquid funds are available to meet financial commitments on a timely basis.
Financial institutions must maintain liquidity to meet day-to-day requirements
of depositors and borrowers, take advantage of market opportunities and provide
a cushion against unforeseen needs.

     Liquidity of the Bank is derived primarily from core deposits, principal
payments received on loans, the sale and maturity of investment securities, net
cash provided by operating activities, and access to other funding sources. The
most stable source of liability funded liquidity is deposit growth and retention
of the core deposit base. The principal sources of asset funded liquidity are
available-for-sale investment securities, cash and due from banks, Federal funds
sold, securities purchased under agreements to resell, and loans and interest
bearing deposits with other banks maturing within one year. Additionally,
liquidity is provided by bank lines of credit, repurchase agreements, and the
ability to borrow from the Federal Reserve Bank and Federal Home Loan Bank.


     The ALCO monitors and manages the relationship of earning assets to


                                       14


interest bearing liabilities and the responsiveness of asset yields, interest
expense, and interest margins to changes in market interest rates. At March 31,
2006, the consolidated statement of financial condition was rate sensitive by
$223 million more liabilities than assets scheduled to reprice within one year,
or approximately 0.90%.

                              RESULTS OF OPERATIONS
                              ---------------------

     Net income for the three month period ended March 31, 2006, was $9.93
million, compared to $6.94 million for the same period in 2005. Diluted net
income per common share was $0.48 for the three month period ended March 31,
2006, compared to $0.33 for the same period in 2005. Return on average common
shareholders' equity was 11.53% for the three months ended March 31, 2006,
compared to 8.60% in 2005. The return on total average assets was 1.18% for the
three months ended March 31, 2006, compared to 0.84% in 2005.

     The increase in net income for the three months ended March 31, 2006, over
the first three months of 2005, was primarily the result of an increase in net
interest income, gains in venture partnership investments, and a decrease in
salaries and employee benefit expense. These positive impacts to net income were
somewhat offset by an increase in the income tax provision. Details of the
changes in the various components of net income are discussed further below.

                               NET INTEREST INCOME
                               -------------------

      The taxable equivalent net interest income for the three months ended
March 31, 2006, was $25.72 million, an increase of 6.06% over the same period in
2005. The increase primarily resulted from an increase in the net interest
margin. The net interest margin on a fully taxable equivalent basis was 3.29%
for the three months ended March 31, 2006, compared to 3.15% for the three
months ended March 31, 2005. The increase in the net interest margin was
primarily driven by an increase in the average yield on earning assets, which
increased from 5.12% for the three months ended March 31, 2005 to 6.01% for the
three months ended March 31, 2006. Total average earning assets increased 1.51%
for the three month period ended March 31, 2006, over the comparative period in
2005.

      The increase in the average yield on earning assets was partially the
result of having a larger proportion of average earning assets invested in
higher-yielding loans and leases during the first quarter of 2006 as compared to
the first quarter of 2005. The increase was also partially attributable to
overall increases in market interest rates. Average loan and lease outstandings
also increased over all categories by 7.85% for the three month period, compared
to the same period in 2005. Total average investment securities decreased 18.48%
for the three month period over one year ago as excess funds were used to fund
loan growth rather than for investment purposes. Average mortgages held for sale
decreased 5.05%, due to timing differences in loan sales in the first quarter of
2006 as compared to the first quarter of 2005. Other investments, which include
federal funds sold, time deposits with other banks and trading account
securities, increased for the three month period over one year ago.

     Average interest-bearing deposits increased 1.81% for the three month
period over the same period in 2005. The rate on average interest-bearing
deposits was 3.07% and 2.26% for the three month periods ended March 31, 2006
and 2005, respectively. The increase in the average cost of interest-bearing
deposits during the first three months of 2006 as compared to the first three
months of 2005 was primarily the result of increases in interest rates offered
on deposit products due to increases in market interest rates and increased
competition for deposits across all markets. These higher cost deposits were
pursued due to increased funding needs. The rate on average interest-bearing
funds was 3.28% and 2.39% for the three months ended March 31, 2006 and 2005,
respectively.

                 PROVISION AND RESERVE FOR LOAN AND LEASE LOSSES
                 -----------------------------------------------

     The recovery of provision for loan and lease losses for the three month
periods ended March 31, 2006 and 2005 was $0.30 million and $0.42 million,
respectively. Net recoveries of $0.70 million were recorded for the first
quarter 2006, compared to net charge-offs of $0.60 million for the same quarter
a year ago.

      In the first quarter 2006, loan and lease delinquencies were 0.76% as
compared to 0.57% on March 31, 2005, and 0.38% at the end of 2005. The increase
in the first quarter of 2006 was primarily due to higher delinquencies in the
turbine aircraft portfolio. The reserve for loan and lease losses as a
percentage of loans and leases outstanding at the end of the period was 2.38% as
compared to 2.75% one year ago and 2.38% at December 31, 2005. A summary of loan
and lease loss experience during the three month periods ended March 31, 2006
and 2005 is provided below.

     Nonperforming assets totaled $21.07 million at March 31, 2006, a slight
improvement over the $22.04 million reported at December 31, 2005, and a 17.90%
improvement from the $25.67 million reported at March 31, 2005. The improvement
during the first quarter 2006 was primarily related to a decrease in nonaccrual
loans and leases in all areas with the exception of slight increases in loans
secured by real estate and consumer loans areas. Nonperforming assets as a
percentage of total loans and leases improved to 0.83% at March 31, 2006, from
0.87% at December 31, 2004, and 1.10% at March 31, 2005.

     As of March 31, 2006, the Bank had a $3.32 million standby letter of credit
outstanding which supported bond indebtedness of a customer. Due to the current
financial condition of the customer, if this standby letter of credit is funded,
the Bank likely will foreclose on the real estate securing the customer's
reimbursement obligation. This likely will result in an increase in other real
estate for approximately the same amount as the funding.

     Repossessions consist of aircraft, automobiles, and light trucks at March
31, 2006. At the time of repossession, the recorded amount of the loan or lease
is written down, if necessary, to the estimated value of the equipment or
vehicle by a charge to the reserve for loan and lease losses, unless the
equipment is in the process of immediate sale. Any subsequent write-downs are
included in noninterest expense.

For financial statements purposes, nonaccrual loans and leases are included in
loan and lease outstandings, whereas repossessions and other real estate are
included in other assets. Net credit losses include net charge-offs on loans and
leases and valuation adjustments and gains and losses on disposition of
repossessions and defaulted operating leases.

behind the increase in 2006 was gains on venture capital investments, due to
market value adjustments.

Gains on venture partnership investment totaled $2.05 million for the first
quarter of 2006 compared to gains of $0.74 million for the first quarter of
2005. Insurance commissions, service charges on deposit accounts, equipment
rental income, and trust fees increased during the first quarter of 2006 as
compared to the first quarter 2005.

     Mortgage banking income decreased primarily due to minimal recoveries of
mortgage servicing rights in the first quarter of 2006 compared to significant
recoveries of mortgage servicing rights of $1.09 million in the first quarter of
2005.

The decrease in noninterest expense for the first quarter of 2006 was primarily
due to the reversal of previously recognized stock-based compensation expense
under historical accounting methods related to the estimated forfeiture of stock
awards. This one-time expense reversal, combined with the adoption of SFAS No.
123(R) estimated forfeiture accounting requirements, resulted in a reduction in


                                       19


stock-based compensation of $2.07 million, pre-tax. Stock-based compensation is
discussed further in Note 5 of the Unaudited Notes to Consolidated Financial
Statements. Additionally, group insurance costs were lower for the first quarter
2006 versus the first quarter of 2005. These decreases were partially offset by
additional compensated absence expenses of $0.61 million for the first quarter
of 2006.

       Net occupancy expense decreased for the first quarter of 2006 as compared
to the first quarter of 2005. During the first quarter 2005, 1st Source reviewed
its lease accounting practices in light of the views expressed by the Office of
the Chief Accountant of the SEC in a February 7, 2005 letter to the American
Institute of Certified Public Accountants. As a result of its review, 1st Source
recorded a one-time, net charge of $0.27 million to correct its accounting for
straight-line rent and depreciation of leasehold improvements.

     Furniture and equipment expense increased on a year-over-year basis due to
increased software costs, expenses related to the core system conversion project
and other processing charges. Loan and lease collection and repossession expense
increased slightly on a year-over-year basis as gains on disposition of
repossessed assets decreased and valuation adjustments related to repossessed
assets increased. Professional fees increased marginally as of March 31, 2006,
as compared to March 31, 2005.

     Supplies and communication, business development and marketing expense, and
other expense all remained comparable to 2005 levels. Leased equipment
depreciation increased due to the increase in the operating lease portfolio.

                                  ------------

     The provision for income taxes for the three months ended March 31, 2006,
was $5.07 million, compared to $3.10 million for the same period in 2005. The
effective tax rate was 33.77% for the quarter ended March 31, 2006, compared to
30.88% for the same quarter in 2005. The effective tax rate increased due to an
increase in pre-tax income. The provision for income taxes for the three months
ended March 31, 2006 and 2005, is at a rate which management believes
approximates the effective rate for the year.
