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


Note 1.    Basis of Presentation

     The  unaudited   consolidated  condensed  financial  statements  have  been
prepared in accordance with the  instructions for Form 10-Q and therefore do not
include all  information  and  footnotes  necessary for a fair  presentation  of
financial  position,  results of operations  and cash flows in  conformity  with
generally  accepted  accounting  principles.  The information  furnished  herein
reflects 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
results for the interim periods for which this report is submitted. The 2000 1st
Source Corporation Annual Report on Form 10-K should be read in conjunction with
these statements.


Note 2.    New Accounting Pronouncements

     On January 1, 2001,  1st Source adopted  Statement of Financial  Accounting
Standards No. 133 ("SFAS No. 133"),  "Accounting for Derivative  Instruments and
Hedging  Activities",  as  amended.  SFAS No.  133  establishes  accounting  and
reporting  standards for derivative  instruments and for hedging  activities and
requires  that all  derivative  instruments  be recorded on the balance sheet at
their fair value.  Changes in the fair value of  derivatives  are recorded  each
period in current  earnings  or other  comprehensive  income,  depending  on the
intended use of the derivative and its resulting designation.

     On adoption, it was permitted to transfer  held-to-maturity debt securities
to  available-for-sale  or trading  securities without calling into question the
intent of management to hold other debt securities to maturity in the future. In
conjunction  with the  adoption  of SFAS No.  133,  1st Source  transferred  the
held-to-maturity  portfolio  with an amortized cost of $59.2 million and a gross
unrealized gain of $1.1 million into the available-for-sale portfolio at January
1, 2001.

     In September 2000, the FASB issued SFAS No. 140,  "Accounting for Transfers
and Servicing of Financial Assets and  Extinguishments  of  Liabilities",  which
replaces SFAS No. 125. This  statement  revises the standards for accounting for
securitizations  and other  transfers of  financial  assets and  collateral  and
requires  certain  disclosures,  but carries over most of the provisions of SFAS
No.  125  without  reconsideration.  SFAS No.  140 is  effective  for  transfers
occurring  after March 31, 2001 and for disclosures  relating to  securitization
transactions  and  collateral  for fiscal years ending after  December 15, 2000.
This  statement  is not  expected  to have a  material  effect  on 1st  Source's
financial position or results of operations.

                                     ITEM 2.
                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS


     The following management's  discussion and analysis is presented to provide
information  concerning  the  financial  condition of 1st Source as of March 31,
2001,  as compared to March 31, 2000 and December  31, 2000,  and the results of
operations for the three months ended March 31, 2001 and 2000.

     This  discussion  and  analysis  should  be read in  conjunction  with  1st
Source's  consolidated  condensed  financial  statements  and the  financial and
statistical  data  appearing  elsewhere  in this  report and the 2000 1st Source
Corporation Annual Report on Form 10-K.

     Except for historical  information  contained herein, the matters discussed
in this document,  and other information  contained in 1st Source's SEC filings,
may express "forward-looking  statements." Those statements may involve risk and
uncertainties,  including statements  concerning future events,  performance and
assumptions  and other  statements  that are other than statements of historical
facts.  1st  Source  cautions  readers  not  to  place  undue  reliance  on  any
forward-looking  statements,  which speak only as of the date made.  Readers are
advised that various  factors - including,  but not limited to, changes in laws,
regulations  or  generally   accepted   accounting   principles;   1st  Source's
competitive position within the markets served;  increasing consolidation within
the banking industry; unforeseen changes in interest rates; unforeseen downturns
in the local,  regional or national  economies - could cause 1st Source's actual
results or  circumstances  for future  periods to differ  materially  from those
anticipated or projected.

     1st Source does not undertake,  and specifically  disclaims any obligation,
to  publicly  release  the  result  of any  revisions  that  may be  made to any
forward-looking  statements to reflect the occurrence of unanticipated events or
circumstances after the date of such statements.

                               FINANCIAL CONDITION

     1st Source's assets at March 31, 2001 were $3.25 billion, up 10.7% from the
same time last  year.  Total  loans were up 12.4% and total  deposits  increased
11.3%  over the  comparable  figures  at the end of the first  quarter  of 2000.
Shareholders'  equity was $287.2  million,  up 16.8% from the $245.9 million one
year ago. As of March 31, 2001, the 1st Source  equity-to-assets ratio was 8.8%,
compared to 8.4% a year ago.

     Nonperforming  assets at March  31,  2001,  were  $25,005,000  compared  to
$24,462,000  at December  31,  2000,  an increase of 2.22%.  At March 31,  2001,
nonperforming  assets were 1.04% of net loans  compared to 1.06% at December 31,
2000.

     Loans are reported at the  principal  amount  outstanding,  net of unearned
income.  Loans  identified as held-for- sale are carried at the lower of cost or
market determined on an aggregate basis. Loans held-for-sale were $114.3 million
and $54.4 million at March 31, 2001 and 2000, respectively.

     Included in Other Assets are capitalized  mortgage  servicing  rights.  The
costs of purchasing the rights to service  mortgage  loans  originated by others
are deferred and amortized as  reductions of mortgage  servicing fee income over
the estimated  servicing period in proportion to the estimated  servicing income
to be received.  SFAS No. 140 allows companies that sell originated or purchased
loans and retain the  related  servicing  rights,  to  allocate a portion of the
total costs of the loans to servicing  rights,  based on  estimated  fair value.
Fair value is estimated based on market prices,  when available,  or the present
value of future net servicing income,  adjusted for such factors as discount and
prepayment rates.

     In the first quarter of 2001, 1st Source completed the sale of $1.0 billion
in  principal  value of its  mortgage  servicing  rights  held by its  Trustcorp
Mortgage  Company  subsidiary.  This  servicing  sale was in  addition to normal
quarterly sales levels,  and was made possible by favorable  market  conditions.
Pre-tax income of $11.06 million ($6.87 million, net of tax) was recorded in the
first  quarter,  2001 on this  transaction.  As of March 31, 2001 and 2000,  the
carrying value of mortgage servicing rights was $12.3 million and $21.2 million,
respectively.


CAPITAL RESOURCES

     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.  These
guidelines  require all banks to maintain a minimum  leverage  capital  ratio of
4.00% for adequately capitalized banks and 5.00% for well-capitalized banks. 1st
Source's leverage capital ratio was 10.17% at March 31, 2001.

     The Federal Reserve Board has established risk-based capital guidelines for
U.S. banking  organizations.  The guidelines  established a conceptual framework
calling for risk  weights to be assigned  to on and  off-balance  sheet items in
arriving at risk-adjusted  total assets,  with the resulting ratio compared to a
minimum standard to determine whether a bank has adequate  capital.  The minimum
standard  risk-based  capital ratios  effective in 2001 are 4.00% for adequately
capitalized  banks and 6.00% for  well-capitalized  banks for Tier 1  risk-based
capital and 8.00% and 10.00%,  respectively,  for total risk-based capital.  1st
Source's  Tier 1 risk-based  capital  ratio on March 31, 2001 was 11.95% and the
total risk-based capital ratio was 13.21%.

                                     - 8 -

LIQUIDITY AND INTEREST RATE SENSITIVITY

     Asset and  liability  management  includes the  management of interest rate
sensitivity and the maintenance of an adequate liquidity  position.  The purpose
of liquidity management is to match the sources and uses of funds to anticipated
customers' deposits and withdrawals, to anticipate borrowing requirements and to
provide  for the cash flow needs of 1st Source.  The  purpose of  interest  rate
sensitivity  management  is to stabilize net interest  income during  periods of
changing interest rates.

     Close  attention is given to various  interest  rate  sensitivity  gaps and
interest  rate  spreads.  Maturities  of rate  sensitive  assets  are  carefully
maintained relative to the maturities of rate sensitive liabilities and interest
rate  forecasts.  At March 31,  2001,  the  consolidated  statement of financial
condition  was rate  sensitive  by  $238,579,000  more  liabilities  than assets
scheduled  to  reprice  within  one  year  or  87.90%.  Management  adjusts  the
composition  of  its  assets  and   liabilities  to  manage  the  interest  rate
sensitivity gap based upon its expectations of interest rate fluctuations.

                              RESULTS OF OPERATIONS

NET INCOME

     Net income for the three month period ended March 31, 2001, was $13,643,000
compared to $8,685,000 for the equivalent period in 2000. The primary reason for
the  increase was the gain on the sale of the $1.0  billion  mortgage  servicing
rights in the first quarter, 2001, offset by an increased loan loss provision.

     Diluted net income per common share  increased to $0.65 for the three month
period  ended  March 31,  2001,  from $0.41 in 2000.  Return on  average  common
shareholders'  equity was  19.91% for the three  months  ended  March 31,  2001,
compared to 14.46% in 2000. The return on total average assets was 1.73% for the
three months ended March 31, 2001, compared to 1.22% in 2000.


NET INTEREST INCOME

     The taxable equivalent net interest income for the three month period ended
March 31, 2001,  was  $27,990,000,  an increase of 7.21% over the same period in
2000. The net interest margin on a fully taxable  equivalent basis was 3.90% for
the three month  period  ended  March 31,  2001  compared to 4.05% for the three
month  period  ended March 31, 2000 and 3.82% for the three month  period  ended
December 31, 2000. The net interest  margin has declined in the past year due to
the costs of funds  rising more than the yield on interest  earning  assets;  in
part,  due to the greater  reliance on brokered,  negotiated  rate  deposits and
jumbo certificates of deposits to meet funding needs.

     Total average  earning assets  increased  12.05% for the three month period
ended  March  31,  2001,  over the  comparative  period in 2000.  Total  average
investment  securities  increased 3.66% for the three month period over one year
ago primarily due to an increase of investments in U.S.  Government  Securities.
Average loans  increased by 13.96% for the three month  period,  compared to the
same period in 2000, due to growth in loan volume in commercial and agriculture,
commercial loans secured by transportation and construction  equipment and loans
secured by real estate.  The taxable  equivalent yields on total average earning
assets were 8.70% and 8.36% for the three month  periods  ended March 31,  2001,
and 2000, respectively.

     Average deposits  increased 11.05% for the three month period over the same
period from 2000. The cost rate on average  interest-bearing funds was 5.55% and
4.97% for the three months ended March 31, 2001,  and 2000.  The majority of the
growth in deposits from last year has occurred in  certificates of deposits with
maturities  greater  than one year,  brokered  certificates  of deposits and NOW
accounts.

     The following table sets forth consolidated  information  regarding average
balances and rates.

PROVISION AND RESERVE FOR LOAN LOSSES

     The provision  for loan losses for the first  quarter of 2001  increased to
$7,295,000 as compared to $3,918,000 for the first quarter of 2000. The increase
is primarily due to increased  charge-offs  over the past two quarters and to an
increase in loan  delinquencies  to 2.13% at March 31, 2001 as compared to 0.54%
at March 31, 2000 and 1.03% at the end of 2000.  Net  Charge-offs  of $3,065,000
have been  recorded in the first quarter 2001,  compared to Net  Charge-offs  of
$3,348,000  in the first quarter 2000 and  $2,204,000  in the fourth  quarter of
2000. A summary of loan loss experience  during the three months ended March 31,
2001 and 2000 and for year ended December 31, 2000 is provided below.

     It is management's  opinion that the reserve for loan losses is adequate to
absorb losses inherent in the loan portfolio as of March 31, 2001.


NONINTEREST INCOME

     Noninterest  income for the three month periods  ended March 31, 2001,  and
2000 was $30,204,000 and $17,114,000, respectively, an increase of 76.49%. Trust
fees increased 6.33%, service charges on deposit accounts increased 34.83%, loan
servicing and sale income increased  170.20%,  equipment rental income increased
26.50% and other income increased 45.95%.  Service charges on deposits increased
due to the  implementation  of an  overdraft  protection  program  during  2000.
Servicing  and sale  income  increased  due to the $1 billion  sale of  mortgage
servicing  rights in the first quarter,  2001. The increase in equipment  rental
income was primarily due to growth in operating leases.  Investment Security and
other net gains for March 31,  2001,  were  $1,032,000  compared to net gains of
$497,000 in 2000,  an  increase  of  107.65%.  The net gains for both years were
primarily attributed to certain partnership and venture capital investments.

NONINTEREST EXPENSE

     Noninterest  expense for the three month period  ended March 31, 2001,  was
$28,017,000,  an  increase of 15.36% over the same period in 2000 and 4.31% over
the prior  quarter  ended  December  31, 2000.  Salaries  and employee  benefits
increased  13.57% and 14.15% from the three month  periods  ended March 31, 2000
and  December  31,  2000,  respectively,  primarily  due to an  increase in base
salaries in the first quarter,  2001. Base salaries  increased  partially due to
increased  mortgage  loan  commissions  and to fewer open  positions  within the
organization.  Net occupancy expense  increased 12.95%,  furniture and equipment
expense  increased  6.13%,  depreciation on leased equipment  increased  28.06%,
supplies and communications  expense increased 4.11%,  business  development and
marketing expense increased 13.46%,  and miscellaneous  other expenses increased
24.19% over the same period in 2000.  The  increase  in  depreciation  of leased
equipment  is due to a  significant  volume  increase  from the prior year.  The
miscellaneous  other expense increase from one year ago is attributed  primarily
to an increase in professional fees.


INCOME TAXES

     The  provision  for income taxes for the three month period ended March 31,
2001, was $7,818,000  compared to $4,845,000 for the comparable  period in 2000.
The  provision  for income taxes for the three months ended March 31, 2001,  and
2000, is at a rate which management believes approximates the effective rate for
the year.
