                        Report of Independent Accountants


Board of Directors
Trustcorp Mortgage Company


We have audited the accompanying statements of net assets available for benefits
of the  Trustcorp  Mortgage  Company  Employee  Retirement  Savings  Plan  as of
December 31, 2001 and 2000, and the related  statements of changes in net assets
available for benefits for the years then ended. 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 auditing standards generally accepted
in the 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,  2001 and 2000,  and the changes in its net assets  available  for
benefits for the years then ended,  in  conformity  with  accounting  principles
generally accepted in the United States.

Our audits  were  performed  for the  purpose of forming an opinion on the basic
financial statements taken as a whole. The accompanying supplemental schedule of
assets held for  investment  purposes at end of year as of December 31, 2001, is
presented for purposes 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  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.

           Trustcorp Mortgage Company Employee Retirement Savings Plan

                          Notes to Financial Statements

                                December 31, 2001




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 attained age 21 and 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 15% of their annual  compensation
as a salary  reduction  contribution  to the Plan  under  Section  401(k) of the
Internal Revenue Code. When applying the discretionary  matching  contributions,
only salary reductions up to six percent (6%) of eligible employee  compensation
is  considered.   For  the  year  2001  and  2000,  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.  For the
years 2001 and 2000, this  discretionary  contribution was equal to $202,000 and
$76,000, respectively.

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.

                    Notes to Financial Statements (continued)



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 ten 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, 2001 and 2000,
$283,396 and $311,778  respectively,  has been allocated to participants who had
effectively withdrawn from the Plan 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  aggregate  current  value as  reported  by the  funds.  Loans to
participants are stated at cost, which approximates fair value.


2. Summary of Significant Accounting Policies (continued)

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 Trustcorp Mortgage Company Employee  Retirement
Savings Plan (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.

3. Investments

During 2001 and 2000, the Plan's investments  (including  investments purchased,

5. Income Tax Status

The Plan has received a determination  letter from the Internal  Revenue Service
dated July 18, 1994,  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.
