         1st Source, through its principal subsidiary 1st Source Bank (the

bank in 1922, is a member of the Federal Reserve System and its deposits are
insured by the Federal Deposit Insurance Corporation (the "FDIC") to the extent
provided by law. The Bank is headquartered in South Bend, Indiana, which is in
northern Indiana, approximately 95 miles east of Chicago and 140 miles north of
Indianapolis. Its principal market area consists of nine counties in northern
Indiana and three counties in southwestern lower Michigan. South Bend, in St.
Joseph County, is the largest city in its market area, and is a regional center
for educational institutions, health care, financial, accounting and legal
services and retailing.

         1st Source's other subsidiaries include 1st Source Leasing, Inc., an
originator and servicer of personal property leases to businesses nationwide,
1st Source Insurance, Inc., a general property and casualty insurance agency in
South Bend, 1st Source Capital Corporation, a licensed small business investment

BUSINESS STRATEGY AND OBJECTIVES

         1st Source, as part of its "Vision 2000" strategic planning process
commenced in 1995, has identified several business objectives and strategies
which focus on growth and customer service. The principal objectives of 1st
Source under Vision 2000 have been to (i) increase financial performance and
market share, (ii) provide exceptional customer service, (iii) enhance credit
quality, and (iv) maintain cost controls.

         1st Source has employed the following strategies to further its Vision
2000 objectives:

         1. Increase market share in each market served and as a percentage of
each customer's relationship. 1st Source has opened 15 new banking locations
from 1995 through 1998 as part of its banking center expansion program designed
to maintain its position as one of the dominant financial institutions in its
market area -- which



                                       2
<PAGE>   3

includes nine counties in northern Indiana and three counties in southwestern
lower Michigan. Management believes that such a strategy allows the most
effective and efficient use of 1st Source's marketing resources and assures that
1st Source's banking offices are accessible to a majority of the people residing
in the markets served. 1st Source's goal is to deliver highly personal and
superior customer services through each of its banking facilities and to meet a
higher percentage of each customer's financial needs through personal
relationship management.

         2. Expand fee-based businesses. 1st Source currently provides a number
of fee-based services to its clients, the major services being trust, mortgage
banking, and insurance. 1st Source believes that additional sources of fee
income are available from existing relationships and that existing fee-based
product lines can be used effectively in developing new relationships with
customers. 1st Source also believes that customers are more loyal and responsive
to its products and services when a large percentage of a customer's financial
services are provided directly by 1st Source. 1st Source's fee-based businesses
are designed to strengthen the relationship between 1st Source and its
customers.

         3. Expand the national niche businesses across the United States taking
advantage of specialized opportunities. 1st Source caters to specialized
national market niches that management believes are not being well served by
either the credit subsidiaries of manufacturers or by other financial
institutions. Asset-based lending and personal relationship management of the
customer base, together with an efficient method of operation, is the focus of
the Bank's Specialty Finance Group, which provides such services. Additional
experienced sales people have been and will be added to ensure better geographic
coverage in areas of opportunity. 1st Source has also pursued a strategy of
securitizing loan receivables so that this Group's business growth is not
totally dependent on deposit funding.

         4. Actively managing credit quality. 1st Source has adopted a proactive
credit management process with loan officers maintaining responsibility for the
quality of the credits they originate and manage. The credit management process
is supported by a collective and collaborative review and approval process and
is balanced by a review, evaluation and grading process undertaken by an
objective third party. Senior management is actively involved in the management
of the process and incentive compensation is based on 1st Source's overall
credit experience.

BANKING AND FINANCIAL SERVICES

         The organization offers a broad range of consumer and commercial
         banking services through its lending operations, retail branches and
         fee based businesses.

         Loans and Leases

         -        1st Source's commercial and agriculture loans at December 31,
                  1998, were approximately $399 million and were 21.2% of total
                  loans outstanding. The primary focus of this lending area is
                  with privately-held or closely-controlled firms in 1st
                  Source's regional market area of Northern Indiana and
                  Southwest Michigan.

         -        Commercial loans secured by transportation  and construction 
                  equipment totaled $732 million, or 38.9% of total loans
                  outstanding, at December 31, 1998. This loan area concentrates
                  on specialty finance lending for automobile leasing and rental
                  companies, truck leasing companies, privately-owned aircraft
                  for businesses and individuals and heavy duty trucks and other
                  equipment used in the construction business. Currently, 1st
                  Source has 14 locations nationwide supporting these lending
                  activities. Loan sale and servicing income resulting from loan
                  securitizations from these specialty


                                       3
<PAGE>   4


                  finance lending activities totaled $8.57 million in 1998. 1st
                  Source also generates equipment rental income through the
                  leasing of various automobiles, construction equipment and
                  other equipment to customers through operating leases, where
                  1st Source retains ownership of the property being leased.
                  Total equipment rental income for 1998 totaled $12.6 million
                  with depreciation on this equipment amounting to $8.9 million.

         -        Loans secured by real estate amounted to $631 million, which
                  was approximately 33.5% of total loans outstanding, at
                  December 31, 1998. The primary focus of this lending area is
                  commercial real estate and residential mortgage lending in the
                  regional market area of Northern Indiana and Southwest
                  Michigan. Most of the residential mortgages are sold into the
                  secondary market and serviced by 1st Source's mortgage
                  subsidiary, Trustcorp Mortgage Company.

         -        1st Source's consumer loans at December 31, 1998, amounted to
                  $119 million and 6.4% of total loans outstanding. Consumer
                  loans are primarily all other non-real estate loans to
                  individuals in 1st Source's regional market area.

         Deposits

         Through its network of 47 branches in 12 counties in Indiana and
         Michigan, 1st Source generates deposits to fund its lending activities.
         The total deposits at December 31, 1998 were $2.18 billion. Enhancing
         customer service, 1st Source offers banking services, in addition to
         its traditional branches, through its network of 48 automatic teller
         machines, bank by phone services and through the internet. Service
         charges on deposit accounts totaled $5.8 million for 1998.

         Fee Based Businesses

         1st Source maintains various fee based businesses to complement net
         interest income.

         -        Trust fees are generated from employee benefit services,
                  personal and agency trusts and estate planning. In 1998, trust
                  fees were approximately $8.3 million.

         -        Mortgage loan sale and servicing income for 1998 amounted to
                  $6.55 million. Income from loan sale and servicing is
                  generated from the mortgage banking operations of Trustcorp
                  Mortgage Company. Trustcorp serviced approximately $1.87
                  billion of mortgage loans at December 31, 1998.

         -        Insurance   commissions  from  1st  Source's  property  and  
                  casualty  insurance  agency  totaled $1.30 million for 1998.

COMPETITION

         The activities in which 1st Source and the Bank engage are highly
competitive. Those activities and the geographic markets served involve
primarily competition with other banks, some of which are affiliated with large
bank holding companies headquartered outside of 1st Source's principal market.
Larger financial institutions competing within 1st Source's principal market,
but headquartered elsewhere, include KeyBank, Norwest Bank, Banc One, Standard
Federal Bank and National City Corporation. Competition among financial
institutions is based upon interest rates offered on deposit accounts, interest
rates charged on loans and other credit and service charges, the quality of
services rendered, the convenience of banking facilities and, in the case of
loans to large commercial borrowers, relative lending limits.




                                       4
<PAGE>   5
         In addition to competing with other banks within its primary service
areas, the Bank also competes with other financial intermediaries, such as
credit unions, industrial loan associations, securities firms, insurance
companies, small loan companies, finance companies, mortgage companies, real
estate investment trusts, certain governmental agencies, credit organizations
and other enterprises. Additional competition for depositors' funds comes from
United States Government securities, private issuers of debt obligations and
suppliers of other investment alternatives for depositors. Many of 1st Source's
non-bank competitors are not subject to the same extensive federal regulations
that govern bank holding companies and banks. Such non-bank competitors may, as
a result, have certain advantages over 1st Source in providing some services.

         1st Source competes against these financial institutions by offering
innovative products and highly personalized services. 1st Source also relies on
a history in the market dating back to 1863, relationships that long-term
employees have with their customers, and the capacity for quick local
decision-making.

EMPLOYEES

         1st Source employs approximately 1,036 persons on a full-time
equivalent basis. 1st Source provides a wide range of employee benefits and
considers employee relations to be good.

REGULATION AND SUPERVISION

         GENERAL. 1st Source and the Bank are extensively regulated under
federal and state law. These laws and regulations are intended to protect
depositors, not shareholders. To the extent that the following information
describes statutory or regulatory provisions, it is qualified in its entirety by
reference to the particular statutory and regulatory provisions. Any change in
applicable laws or regulations may have a material effect on the business and
prospects of 1st Source. The operations of 1st Source may be affected by
legislative changes and by the policies of various regulatory authorities. 1st
Source is unable to predict the nature or the extent of the effects on its
business and earnings that fiscal or monetary policies, economic controls or new
federal or state legislation may have in the future.

         1st Source is a registered bank holding company under the Bank Holding
Company Act of 1956 (the "BHCA") and, as such, is subject to regulation,
supervision and examination by the Board of Governors of the Federal Reserve
System (the "Federal Reserve"). 1st Source is required to file annual reports
with the Federal Reserve and to provide the Federal Reserve such additional
information as it may require.

         The Bank, as an Indiana state bank, is supervised by the Indiana
Department of Financial Institutions (the "DFI") and the Federal Reserve. As
such, the Bank is regularly examined by and subject to regulations promulgated
by the DFI and the Federal Reserve. Because the FDIC provides deposit insurance
to the Bank, the Bank is also subject to supervision and regulation by the FDIC
(even though the FDIC is not its primary federal regulator).

         BANK AND BANK HOLDING COMPANY REGULATION.  As noted above, both 1st
Source and the Bank are subject to extensive regulation and supervision.

         Bank Holding Company Act. Under the BHCA, as amended, the activities of
a bank holding company, such as 1st Source, are limited to business so closely
related to banking, managing or controlling banks as to be a proper incident
thereto. 1st Source is also subject to capital requirements applied on a
consolidated basis in a form





                                       5
<PAGE>   6

substantially similar to those required of the Bank. The BHCA also requires a
bank holding company to obtain approval from the Federal Reserve before (i)
acquiring, or holding more than 5% voting interest in any bank or bank holding
company, (ii) acquiring all or substantially all of the assets of another bank
or bank holding company, or (iii) merging or consolidating with another bank
holding company.

         The BHCA also restricts non-bank activities to those which, by statute
or by Federal Reserve regulation or order, have been identified as activities
closely related to the business of banking or of managing or controlling banks.

         Financial Institutions Reform, Recovery, and Enforcement Act of 1989.
The Financial Institutions Reform, Recovery, and Enforcement Act of 1989
("FIRREA") reorganized and reformed the regulatory structure applicable to
financial institutions generally.

         The Federal Deposit Insurance Corporation Improvement Act of 1991. The
Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA") was
adopted to supervise and regulate a wide variety of banking issues. In general,
FDICIA provides for the recapitalization of the Bank Insurance Fund ("BIF"),
deposit insurance reform, including the implementation of risk-based deposit
insurance premiums, the establishment of five capital levels for financial
institutions ("well capitalized," "adequately capitalized," "undercapitalized,"
"significantly undercapitalized" and "critically undercapitalized") that would
impose more scrutiny and restrictions on less capitalized institutions, along
with a number of other supervisory and regulatory issues.

         Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994.
Congress enacted the Riegle-Neal Interstate Banking and Branching Efficiency Act
of 1994 (the "Interstate Act") in September 1994. Beginning in September 1995,
bank holding companies have the right to expand, by acquiring existing banks,
into all states, even those which had theretofore restricted entry. The
legislation also provides that, subject to future action by individual states, a
holding company has the right to convert the banks which its owns in different
states to branches of a single bank. The states of Indiana and Michigan have
adopted the interstate branching provisions of the Interstate Act.

         Economic Growth and Regulatory Paperwork Reduction Act of 1996. The
Economic Growth and Regulatory Paperwork Reduction Act of 1996 (the "EGRPRA")
was signed into law on September 30, 1996. EGRPRA streamlined the non-banking
activities application process for well-capitalized and well-managed bank
holding companies.

         Regulations Governing Capital Adequacy. The federal bank regulatory
agencies use capital adequacy guidelines in their examination and regulation of
bank holding companies and banks. If the capital falls below the minimum levels
established by these guidelines, the bank holding company or bank may be denied
approval to acquire or establish additional banks or nonbank businesses or to
open facilities. The various regulatory capital requirements that 1st Source is
subject to are disclosed on page 42 in Footnote "O" of the annual shareholders
report for year ended December 31, 1998, and is incorporated herein by
reference. Management of 1st Source believes that the risk-weighting of assets
and the risk-based capital guidelines do not have a material adverse impact on
1st Source's operations or on the operations of the Bank.

         Community Reinvestment Act. The Community Reinvestment Act of 1977
requires that, in connection with examinations of financial institutions within
their jurisdiction, the federal banking regulators must evaluate the record of
the financial institutions in meeting the credit needs of their local
communities, including low and moderate income neighborhoods, consistent with
the safe and sound operation of those banks. These factors are also considered
in evaluating mergers, acquisitions and applications to open a branch or
facility.


                                       6
<PAGE>   7
         Regulations Governing Extensions of Credit. The Bank is subject to
certain restrictions imposed by the Federal Reserve Act on extensions of credit
to the bank holding company or its subsidiaries, or investments in their
securities and on the use of their securities as collateral for loans to any
borrowers. These regulations and restrictions may limit the ability of 1st
Source to obtain funds from the Bank for its cash needs, including funds for
acquisitions and for payment of dividends, interest and operating expenses.
Further, under the BHCA and certain regulations of the Federal Reserve, a bank
holding company and its subsidiaries are prohibited from engaging in certain
tying arrangements in connection with any extension of credit, lease or sale of
property or furnishing of services.

         The Bank is also subject to certain restrictions imposed by the Federal
Reserve Act on extensions of credit to executive officers, directors, principal
shareholders or any related interest of such persons. Extensions of credit (i)
must be made on substantially the same terms, including interest-rates and
collateral, and following credit underwriting procedures that are not less
stringent than, as those prevailing at the time for comparable transactions with
persons not covered above and who are not employees, and (ii) must not involve
more than the normal risk of repayment or present other unfavorable features.
The Bank is also subject to certain lending limits and restrictions on
overdrafts to such persons.

         Reserve Requirements. The Federal Reserve requires all depository
institutions to maintain reserves against their transaction accounts and
non-personal time deposits. Reserves of 3% must be maintained against total
transaction accounts of $47.8 million or less (subject to adjustment by the
Federal Reserve) and 10% must be maintained against that portion of total
transaction accounts in excess of such amount.

         Dividends. The ability of the Bank to pay dividends and management fees
is limited by various state and federal laws, by the regulations promulgated by
its primary regulators and by the principles of prudent bank management.

         Monetary Policy and Economic Control. The commercial banking business
in which 1st Source engages is affected not only by general economic conditions,
but also by the monetary policies of the Federal Reserve. Changes in the
discount rate on member bank borrowing, availability of borrowing at the
"discount window," open market operations, the imposition of changes in reserve
requirements against member banks deposits and assets of foreign branches, and
the imposition of and changes in reserve requirements against certain borrowings
by banks and their affiliates are some of the instruments of monetary policy
available to the Federal Reserve. These monetary policies are used in varying
combinations to influence overall growth and distributions of bank loans,
investments and deposits, and such use may affect interest rates charged on
loans or paid on deposits. The monetary policies of the Federal Reserve have had
a significant effect on the operating results of commercial banks and are
expected to do so in the future. The monetary policies of the Federal Reserve
are influenced by various factors, including inflation, unemployment, short-term
and long-term changes in the international trade balance and in the fiscal
policies of the U.S. Government. Future monetary policies and the effect of such
policies on the future business and earnings of 1st Source and the Bank cannot
be predicted.

1st Source's reserve for loan losses is provided for by direct charges to
operations. Losses on loans are charged against the reserve and likewise,
recoveries during the period for prior losses are credited to the reserve. The
loss reserve is maintained at a level considered by management to be adequate to
absorb anticipated losses from loans presently outstanding. The provision made
to this reserve is determined by management based on the risk factors and
general economic conditions affecting the loan portfolio, including changes in
the portfolio mix and past loan loss experience. Management of 1st Source is
constantly reviewing the status of the loan portfolio to identify borrowers that
might develop financial problems, in order to aid borrowers in the handling of
their accounts and to prevent sizable unexpected losses.

In 1998, after management's assessment of loan quality, 1st Source made a charge
of $9.16 million to operations as a provision for loan losses. At December 31,
1998, the reserve for loan losses was $40.93 million, or 2.18% of loans
outstanding net of unearned discount.

ITEM 2.       PROPERTIES

1st Source's headquarters building is located in downtown South Bend. In 1982,
the land was leased from the City of South Bend on a 49-year lease, with a
50-year renewal option. The building is part of a larger complex, including a
300-room hotel and a 500-car parking garage. 1st Source sold the building and
entered into a leaseback agreement with the purchaser for a term of 30 years.
The bank building is a structure of approximately 160,000 square feet, with 1st
Source and its subsidiaries occupying approximately 70% of the available office
space, and approximately 30% presently subleased to unrelated tenants.

1st Source also owns property and/or buildings on which 28 of the bank
subsidiary's 47 banking offices are located, including the facilities in
Elkhart, LaPorte, Marshall, Porter, St. Joseph and Starke Counties in the state
of Indiana, as well as a parking facility, two buildings housing drive-in
banking plazas, a records retention facility, and a computer operations center.
In 1995, 1st Source reacquired its former headquarters building through
foreclosure. It is being refurbished for additional tenants and 1st Source use.
The remaining properties utilized by the subsidiary are leased from unrelated
parties.

                                 APRIL 16, 1998


     RESOLVED, that the By-Laws of this Corporation shall be amended at Article

shall be eleven (11)", because this Board has determined on the advice of
counsel that such action is not required by law or regulation.

Agreement shall end on December 31, five (5) years subsequent to the date of the
last automatic extension.

          3. Compensation and Benefits.

          (a) Base Salary. Executive shall be paid a Base Salary of not less
     than Four Hundred Fifty Thousand Dollars ($450,000) per annum initially,
     increasing to Five Hundred Thousand Dollars ($500,000) per annum effective

          (d) Life Insurance. Employer will purchase $2 million ($2,000.000.00)
     of life insurance for the benefit of Executive, his family or estate as he
     may direct.

          (e) Death Benefit. If Executive should die during the term of this
     Agreement, Employer shall pay to his estate or such other beneficiary that
     the Executive may designate in writing an additional death benefit equal to
     three (3) times the base salary and bonus paid to Executive in the
     preceding year.

          (f) Additional Benefits. Executive shall be entitled to receive six
     (6) weeks vacation each year without reduction of compensation during the
     term of this Agreement.

          A club membership will be provided by Employer for Executive to at

     with the initiation fees, monthly fee and appropriate business related
     expenses paid by Employer.

          One automobile shall be provided by Employer to Executive on a full
     lease basis consistent with the title and position of Executive.

          4. Disability. In the event that this Agreement is terminated by
reason of Executive's Disability, Executive will continue to receive his Base

participate in any other disability compensation programs, including any Salary

For purposes of this Agreement, "Disability" means Executive's inability by
reason of illness or other physical or mental impairment to perform the duties
required by his employment for any consecutive one hundred eighty (180) day
period, provided that written notice of any termination for Disability shall
have been given by Employer to Executive prior to the full resumption by him of
the performance of such duties.

          5. Termination by Employer; Death or Disability.

          (a) With Cause. In the event the Board determines that Executive is
     guilty of gross dereliction of duty or of fraud or dishonesty in connection
     with the performance of his duties under this Agreement, the Board may
     terminate this Agreement such termination to be effective thirty (30) days
     after the Board gives written notice to Executive setting forth with
     specificity the reason or cause for terminating the Agreement. In such
     event, the compensation and other benefits provided for in this Agreement
     shall




                                       3


<PAGE>   4

     terminate on the date specified by the Board in the written notice of
     termination delivered to Executive.

          (b) Without Cause. If Employer shall discharge Executive from his
     employment hereunder for any reason other than one set forth in Section
     5(a), or if it shall be determined by a court of competent jurisdiction
     that the discharge under Section 5(a) was not justified, or if Employer
     violates the provisions of this Agreement in a material manner, Executive
     shall have the right to terminate his obligations and duties hereunder, but
     the rights of Executive to receive the compensation provided for in Section
     3 shall continue nevertheless to be fully in effect for the remaining term
     of this Agreement in the same manner as would have been payable absent such
     termination. Notwithstanding the foregoing Employer shall have the right at
     any time after the termination contemplated by this Section 5(b) to pay
     Executive in a lump sum the then present value of the amount payable to
     Executive discounted at the then current savings rate for Bank under this
     Section (b).

          (c) Death or Disability. This Agreement shall terminate in the event
     of the death or Disability of Executive. In such event, Executive, his
     estate or designee shall be entitled to the death or Disability benefits
     provided in Sections 3(e) and 4 of this Agreement.

          6. Termination By Executive. Executive may, at any time upon written
notice to Employer, immediately terminate his employment for Good Reason. For
purposes of this Agreement, "Good Reason" shall mean any adverse change in
Executive's status or position as Chairman of the Board, President and Chief
Executive Officer of Employer or as Chairman of the Board and Chief Executive
Officer of Bank or as a director of either including, without limitation, as a
result of a material diminution of his duties or responsibilities or the
assignment to him of duties or responsibilities which, in his reasonable
judgment, are inconsistent with such status or positions, or any removal of
Executive from, or any failure to reappoint or reelect him to, any such position
(except in connection with the termination of his employment pursuant to Section
5(a) or 5(c) or by him for other than Good Reason), or any attempt to require
Executive to relocate outside of the metropolitan area of his current residence.

          (a) If such termination does not follow a Change of Control of
     Employer or Bank, Executive shall continue to receive his Base Salary as
     then in effect for a period of twelve (12) months after the effective date
     of such termination, in the same manner as such Base Salary would have
     become payable pursuant to this Agreement absent such termination.



                                       4

<PAGE>   5

          (b) If such termination occurs within one (1) year after a Change of
     Control of Employer or Bank, as severance pay and in lieu of any further
     compensation for periods subsequent to the effective date of such
     termination, Executive shall receive an amount in cash equal to 2.99 times
     his "annualized includable compensation for the base period" (as defined in
     Section 280G(d)(1) of the Internal Revenue Code of 1986, as amended (the
     "Code")).

          (c) Each of the events specified in the following clauses (i) through
     (iii) of this Section 6(c) shall be deemed a "Change in Control": (i) any
     third person, including a "group" within the meaning of Section 13(d)(3) of
     the Securities Exchange Act of 1934, shall become the beneficial owner of
     20% or more of the then outstanding shares of common stock of Employer or
     the combined voting power of the then outstanding voting securities of
     Employer entitled to vote for the election of the Board of Directors of
     Employer (ii) as a result of, or in connection with, any cash tender offer,
     exchange offer, merger or other business combination, sale of assets or
     contested election, or combination of the foregoing, the persons who were
     directors of Employer shall cease to constitute a majority of such Board of
     Directors or (iii) the shareholders of Employer shall approve an agreement
     providing a sale or other disposition of all or substantially all the
     assets of Employer.

          7. Assignment. This Agreement is a personal contract, and the rights
and interest of Executive hereunder may not be sold, transferred, assigned,
pledged or hypothecated. Except as otherwise may be herein expressly provided,
this Agreement shall inure to the benefit of and be binding upon Employer and
its successors and assigns.

          8. Amendment. This Agreement may be amended only by a written
instrument signed by the parties hereto after approval by either the Board or
Executive Committee of Employer.

          9. Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Indiana.

          10. Fees and Expenses. If a dispute arises regarding the
interpretation or enforcement of this Agreement and Executive obtains a final
judgment in his favor in a court of competent jurisdiction or his claim is
settled by Employer prior to the rendering of a judgment by such a court, all
reasonable legal fees and expenses incurred by Executive in seeking to obtain or
enforce any right or benefit provided for in this Agreement or otherwise
pursuing his claim shall be paid by Employer, to the fullest extent permitted by
law.

          11. Miscellaneous. No provision of this Agreement may be modified,
waived or discharged unless such waiver, modification or discharge is agreed to
in a writing signed by the parties hereto. No waiver by any party hereto at any
time of any breach by the other party hereto of, or compliance with, any
condition or provision of this Agreement to be performed by such other party
shall be deemed a waiver of similar or dissimilar provisions or conditions at
the same or at any prior or subsequent time. This Agreement supersedes the Prior
Agreement in its entirety.

          12. Restrictive Covenants. In order to induce Employer to enter into
this Agreement, Executive hereby agrees as follows:

          (a) While Executive is employed by Employer and for a period of
     twenty-four (24) months after the effective date of termination of such
     employment for reasons other than those set forth in Section 5(b) of this
     Agreement, Executive shall not divulge or furnish any trade secrets (as
     defined in IND. CODE Section 24-2-3-2) of Employer or any confidential
     information acquired by him while employed by Employer concerning the
     policies, plans, procedures or customers of Employer to any person, firm or
     corporation, other than Employer or with its prior written consent, or use
     any such trade secret or confidential information directly or indirectly
     for Executive's own benefit or for the benefit of any person, firm or
     corporation other than Employer, as such trade secrets and confidential
     information are confidential and shall at all times remain the property of
     Employer.

          (b) For a period of twenty-four (24) months after the effective date
     of termination of Executive's employment hereunder for reasons other than
     those set forth in Section 5(b) of this Agreement, Executive shall not,
     directly or indirectly, provide banking or bank-related services to, or
     solicit the banking or bank-related business of, any customer of Employer
     at the time of such provision of services or solicitation which Employee
     served either alone or with others while employed by Employer within St.
     Joseph, Elkhart, Marshall or LaPorte Counties in the State of Indiana, or
     assist any actual or potential competitor of Employer to provide banking or
     bank-related services to, or solicit the banking or bank-related business
     of, any such customer in any such area, and Executive shall not, directly
     or indirectly, as principal, agent, or trustee, or through the agency of
     any corporation, partnership, trade association, agent or agency, engage in
     any banking or bank-related business or venture which competes with the
     business of Employer as conducted during Executive's employment by Employer
     within such area; provided, however, that Executive may own not more than
     five percent of the voting securities of



                                       6


<PAGE>   7


     any entity providing banking or bank-related services within such area if
     the voting securities of such entity are traded on a national securities
     exchange or quoted on a national interdealer quotation system.

          (c) Executive acknowledges that any violation of this Section 12 would
     cause irreparable harm to Employer, that damages for such harm would be
     incapable of precise measurement and that, accordingly, Employer would not
     have an adequate remedy at law to redress the harm caused by such
     violation. Therefore, Executive agrees that, in addition to any other
     remedy, Employer shall be entitled to immediate (i.e., without prior
     notice) preliminary and final injunctive relief to enjoin and restrain any
     violation of this Section 12.

          If Executive's employment is terminated during the Term of this
Agreement for reasons set forth in Section 5(b) of this Agreement, Executive
shall have no obligations to Employer with respect to trade secrets,
confidential information or noncompetition under this Section 12.

          13. Certain Additional Payments by Employer.

          (a) In the event that Section 280G of the Code is determined to apply
     to the payments to be made by Employer to Executive under this Agreement or
     other compensation or benefit programs, and in the event any excise tax
     ("Excise Tax") that may be imposed by Section 4999 of the Code become
     payable by Executive because of any of the payments made to Executive under
     this Agreement or otherwise, Employer will pay to Executive an additional
     amount ("Gross-up Payment") at least 60 days prior to the due date for
     payment of the Excise Tax. The Gross-up Payment shall be in an amount such
     that, after payment by Executive of all taxes (including, without
     limitation, all income and employment tax and Excise Tax and treating as a
     tax the disallowance of any deduction of Executive by virtue of the
     inclusion of the Gross-up Payment in Executive's adjusted gross income) and
     interest and penalties with respect to such taxes imposed upon the Gross-up
     Payment, Executive retains an amount equal to the Excise Tax. Employer
     shall notify Executive of its determination of the amount of payments under
     this Agreement subject to the Excise Tax (which determination shall be made
     by an accounting firm selected by Employer) and shall provide Executive
     with a receipt for the Excise Tax paid. Executive shall report the amount
     indicated in Employer's notice as the amount subject to the Excise Tax on
     Executive's Federal income tax return.





                                       7
 


<PAGE>   8

          (b) If, for any reason, the Internal Revenue Service or any other
     taxing authority proposes an adjustment to the amount of Excise Tax due
     with respect to any payments or with respect to any additional amounts
     received by Executive pursuant to this Agreement, Executive will notify
     Employer immediately of such proposed adjustment and shall give Employer
     the right to contest such proposed adjustment on Executive's behalf;
     provided, however, that Executive may pay such claim if Employer does not
     take any action prior to the time such payment is due. Employer shall bear
     and pay directly all costs related to or associated with any contest,
     regardless of outcome, and shall have complete control over such contest as
     it relates to the Excise Tax, including whether such contest shall be by
     way of non-payment of the Excise Tax, payment of the Excise Tax under
     protest, or payment of the Excise Tax accompanied by a claim for a refund.
     Employer shall pay to Executive (i) an amount equal to the Excise Tax
     required to be paid to the Internal Revenue Service by Executive as a
     result of the outcome of any contest, any penalties or interest thereon,
     and (ii) a Gross-up Payment computed in the same manner and subject t the
     same adjustments as other Gross-up Payments previously described. Payment
     by Employer of an amount equal to the Excise tax and Gross-up Payment shall
     be made to Executive in advance of the due date for payment of Excise
     Taxes.

          (c) In the event that the amount of any additional payments made
     pursuant to this Section 13 exceeds the amount determined to have been due,
     the excess additional amounts made shall constitute a loan by Employer to
     Executive payable within 30 days after receipt by Executive of the refund
     from the Internal Revenue Service together with any interest received.

          14. No Duty to Mitigate. Executive is not required to mitigate the
amount of salary or benefits payable pursuant to this Agreement upon termination
of his employment by seeking other employment or otherwise, nor shall any amount
provided to be paid by Employer pursuant to this Agreement upon termination of
Executive's employment be reduced by any compensation earned by Employee as a
result of employment by another employer that is not in violation of Executive's
obligations under Section 12.

          15. Severability. The invalidity or unenforceability of any provisions
of this Agreement shall not affect the validity or enforceability of any other
provisions of this Agreement, which shall remain in full force and effect.

          16. Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed to be an original but all of which
together shall constitute one and the same instrument.



                                       8


<PAGE>   9


          17. Resolution of Disputes. Employer agrees to pay promptly as
incurred, to the full extent permitted by law, all legal fees and expenses which
Executive may reasonably incur as a result of any contest, regardless of
outcome, by Employer, Executive or others of the validity of enforceability of,
or liability under, any provision of this Agreement or any guarantee of
performance (including as a result of any contest by Executive concerning the
amount of any payment pursuant to this Agreement).

          IN WITNESS WHEREOF, the parties hereto have executed this Agreement as
of the day and year first written above.

     Executive Incentive Plan at a minimum "partnership" rate of 20% of base
     salary for purposes of determining awards under the Plan. All amounts
     awarded are subject to the terms and conditions of the Plan.

          (c) Benefit Plans. During the term of this agreement, Executive shall
     be entitled to participate, at a level commensurate with his position, in
     all benefit plans Employer presently has or hereafter adopts for its
     officers or employees, including (without limitation) pension, profit
     sharing, stock option or any group life or health insurance,
     hospitalization or other similar plans, any eligibility or waiting periods
     to be waived to the extent feasible.

          (d) Life Insurance. Employer will purchase term life insurance
     coverage equal to two (2) times the initial Base Salary provided in Section
     3(b) for the benefit of Executive, his family or estate as he may direct
     and as provided under Employer's insurance benefit programs.

          (e) Club Membership. A club membership will be provided by Employer
     for Executive to at least one country club and to one club in downtown
     South Bend, Indiana, with the initiation fees, monthly fee and appropriate
     business related expenses paid by Employer.

          4. Disability. In the event that this Agreement is terminated by
reason of Executive's Disability, Executive will continue to receive his Base
Salary for up to one year from the date of the termination and shall also
participate in any other disability compensation programs, including any Salary
Continuance Plan in effect at that time for officers or executives of Employer.
For purposes of this Agreement, "Disability" means Executive's inability by
reason of illness or other physical or mental impairment to perform the duties
required by his employment for any consecutive one hundred eighty (180) day
period, provided that written notice of any termination for Disability shall
have been given by Employer to Executive prior to the full resumption by him of
the performance of such duties.

          5. Termination by Employer; Death or Disability.

          (a) With Cause. In the event the Board determines that Executive is
     guilty of gross dereliction of duty or of fraud or dishonesty in connection
     with the performance of his duties under this Agreement, the Board may
     terminate this Agreement such termination to be effective thirty (30) days
     after the Board gives written notice to Executive setting forth with
     specificity the 


                                       2

<PAGE>   3

     reason or cause for terminating the Agreement. In such event, the
     compensation and other benefits provided for in this Agreement shall
     terminate on the date specified by the Board in the written notice of
     termination delivered to Executive.

          (b) Without Cause. If Employer shall discharge Executive from his
     employment hereunder for any reason other than one set forth in Section
     5(a), or if it shall be determined by a court of competent jurisdiction
     that the discharge under Section 5(a) was not justified, or if Employer
     violates the provisions of this Agreement in a material manner, Executive
     shall have the right to terminate his obligations and duties hereunder, but
     the rights of Executive to receive the compensation provided for in Section
     3 shall continue nevertheless to be fully in effect for the remaining term
     of this Agreement in the same manner as would have been payable absent such
     termination. Notwithstanding the foregoing Employer shall have the right at
     any time after the termination contemplated by this Section 5(b) to pay
     Executive in a lump sum the then present value of the amount payable to
     Executive discounted at the then current savings rate for Bank under this
     Section (b).

          (c) Death or Disability. This Agreement shall terminate in the event 
     of the death or Disability of Executive.

          6. Termination By Executive. Executive may, at any time upon written 
notice to Employer, immediately terminate his employment for Good Reason. For
purposes of this Agreement, "Good Reason" shall mean any adverse change in
Executive's status or position as the President of Bank including, without
limitation, as a result of a material diminution of his duties or
responsibilities or the assignment to him of duties or responsibilities which,
in his reasonable judgment, are inconsistent with such status or positions, or
any removal of Executive from, or any failure to reappoint or reelect him to,
any such position (except in connection with the termination of his employment
pursuant to Section 5(a) or 5(c) or by him for other than Good Reason).

          (a) If such termination does not follow a Change of Control of
     Employer or Bank, Executive shall continue to receive his Base Salary as
     then in effect for a period of twelve (12) months after the effective date
     of such termination, in the same manner as such Base Salary would have
     become payable pursuant to this Agreement absent such termination.

          (b) If such termination occurs within one (1) year after a Change of
     Control of Employer or Bank, as severance pay and in lieu of any further
     compensation for periods subsequent to the effective date of such
     termination,

                                       3

<PAGE>   4


     Executive shall receive an amount in cash equal to 2.99 times his 
     "annualized includable compensation for the base period" (as defined in
     Section 280G(d)(1) of the Internal Revenue Code of 1986, as amended (the
     "Code")).

          (c) Each of the events specified in the following clauses (i) through
     (iii) of this Section 6(c) shall be deemed a "Change in Control": (i) any
     third person, including a "group" within the meaning of Section 13(d)(3) of
     the Securities Exchange Act of 1934, shall become the beneficial owner of
     50% or more of the then outstanding shares of common stock of Employer or
     the combined voting power of the then outstanding voting securities of
     Employer entitled to vote for the election of the Board of Directors of
     Employer (ii) as a result of, or in connection with, any cash tender offer,
     exchange offer, merger or other business combination, sale of assets or
     contested election, or combination of the foregoing, the persons who were
     directors of Employer shall cease to constitute a majority of such Board of
     Directors or (iii) the shareholders of Employer shall approve an agreement
     providing a sale or other disposition of all or substantially all the
     assets of Employer.

          7. Assignment. This Agreement is a personal contract, and the rights 
and interest of Executive hereunder may not be sold, transferred, assigned,
pledged or hypothecated. Except as otherwise may be herein expressly provided,
this Agreement shall inure to the benefit of and be binding upon Employer and
its successors and assigns.

          8. Amendment. This Agreement may be amended only by a written
instrument signed by the parties hereto after approval by either the Board or
Executive Committee of Employer.

          9. Governing Law. This Agreement shall be governed by and construed 
in accordance with the laws of the State of Indiana.

          10. Fees and Expenses. If a dispute arises regarding the 
interpretation or enforcement of this Agreement and Executive obtains a final
judgment in his favor in a court of competent jurisdiction or his claim is
settled by Employer prior to the rendering of a judgment by such a court, all
reasonable legal fees and expenses incurred by Executive in seeking to obtain or
enforce any right or benefit provided for in this Agreement or otherwise
pursuing his claim shall be paid by Employer, to the fullest extent permitted by
law.

          11. Miscellaneous. No provision of this Agreement may be modified, 
waived or discharged unless such waiver, modification or discharge is agreed to
in a writing



                                       4

signed by the parties hereto. No waiver by any party hereto at any time of any
breach by the other party hereto of, or compliance with, any condition or
provision of this Agreement to be performed by such other party shall be deemed
a waiver of similar or dissimilar provisions or conditions at the same or at any
prior or subsequent time.

          12. Restrictive Covenants. In order to induce Employer to enter into 
this Agreement, Executive hereby agrees as follows:

          (a) While Executive is employed by Employer and for a period of
     twenty-four (24) months after the effective date of termination of such
     employment for reasons other than those set forth in Section 5(b) of this
     Agreement, Executive shall not divulge or furnish any trade secrets (as
     defined in IND. CODE Section 24-2-3-2) of Employer or any confidential
     information acquired by him while employed by Employer concerning the
     policies, plans, procedures or customers of Employer to any person, firm or
     corporation, other than Employer or with its prior written consent, or use
     any such trade secret or confidential information directly or indirectly
     for Executive's own benefit or for the benefit of any person, firm or
     corporation other than Employer, as such trade secrets and confidential
     information are confidential and shall at all times remain the property of
     Employer.

          (b) For a period of twenty-four (24) months after the effective date
     of termination of Executive's employment hereunder for reasons other than
     those set forth in Section 5(b) of this Agreement, Executive shall not,
     directly or indirectly, provide banking or bank-related services to, or
     solicit the banking or bank-related business of, any customer of Employer
     at the time of such provision of services or solicitation which Employee
     served either alone or with others while employed by Employer within St.
     Joseph, Elkhart, Marshall or LaPorte Counties in the State of Indiana, or
     assist any actual or potential competitor of Employer to provide banking or
     bank-related services to, or solicit the banking or bank-related business
     of, any such customer in any such area, and Executive shall not, directly
     or indirectly, as principal, agent, or trustee, or through the agency of
     any corporation, partnership, trade association, agent or agency, engage in
     any banking or bank-related business or venture which competes with the
     business of Employer as conducted during Executive's employment by Employer
     within such area; provided, however, that Executive may own not more than
     five percent of the voting securities of any entity providing banking or
     bank-related services within such area if the voting securities of such
     entity are traded on a national securities exchange or quoted on a national
     interdealer quotation system.

          (c) Executive acknowledges that any violation of this Section 12 would
     cause irreparable harm to Employer, that damages for such harm would be
     incapable of precise measurement and that, accordingly, Employer would not
     have an adequate remedy at law to redress the harm caused by such
     violation. Therefore, Executive agrees that, in addition to any other
     remedy, Employer shall be entitled to immediate (i.e., without prior
     notice) preliminary and final injunctive relief to enjoin and restrain any
     violation of this Section 12.

          If Executive's employment is terminated during the Term of this 
Agreement for reasons set forth in Section 5(b) of this Agreement, Executive
shall have no obligations to Employer with respect to trade secrets,
confidential information or noncompetition under this Section 12.

          13. Certain Additional Payments by Employer.

          (a) In the event that Section 280G of the Code is determined to apply
     to the payments to be made by Employer to Executive under this Agreement or
     other compensation or benefit programs, and in the event any excise tax
     ("Excise Tax") that may be imposed by Section 4999 of the Code become
     payable by Executive because of any of the payments made to Executive under
     this Agreement or otherwise, Employer will pay to Executive an additional
     amount ("Gross-up Payment") at least 60 days prior to the due date for
     payment of the Excise Tax. The Gross-up Payment shall be in an amount such
     that, after payment by Executive of all taxes (including, without
     limitation, all income and employment tax and Excise Tax and treating as a
     tax the disallowance of any deduction of Executive by virtue of the
     inclusion of the Gross-up Payment in Executive's adjusted gross income) and
     interest and penalties with respect to such taxes imposed upon the Gross-up
     Payment, Executive retains an amount equal to the Excise Tax. Employer
     shall notify Executive of its determination of the amount of payments under
     this Agreement subject to the Excise Tax (which determination shall be made
     by an accounting firm selected by Employer) and shall provide Executive
     with a receipt for the Excise Tax paid. Executive shall report the amount
     indicated in Employer's notice as the amount subject to the Excise Tax on
     Executive's Federal income tax return.

          (b) If, for any reason, the Internal Revenue Service or any other
     taxing authority proposes an adjustment to the amount of Excise Tax due
     with respect to any payments or with respect to any additional amounts
     received by Executive pursuant to this Agreement, Executive will notify
     Employer


                                       6


<PAGE>   7


     immediately of such proposed adjustment and shall give Employer the right
     to contest such proposed adjustment on Executive's behalf; provided,
     however, that Executive may pay such claim if Employer does not take any
     action prior to the time such payment is due. Employer shall bear and pay
     directly all costs related to or associated with any contest, regardless of
     outcome, and shall have complete control over such contest as it relates to
     the Excise Tax, including whether such contest shall be by way of
     non-payment of the Excise Tax, payment of the Excise Tax under protest, or
     payment of the Excise Tax accompanied by a claim for a refund. Employer
     shall pay to Executive (i) an amount equal to the Excise Tax required to be
     paid to the Internal Revenue Service by Executive as a result of the
     outcome of any contest, any penalties or interest thereon, and (ii) a
     Gross-up Payment computed in the same manner and subject to the same
     adjustments as other Gross-up Payments previously described. Payment by
     Employer of an amount equal to the Excise tax and Gross-up Payment shall be
     made to Executive in advance of the due date for payment of Excise Taxes.

          (c) In the event that the amount of any additional payments made
     pursuant to this Section 13 exceeds the amount determined to have been due,
     the excess additional amounts made shall constitute a loan by Employer to
     Executive payable within 30 days after receipt by Executive of the refund
     from the Internal Revenue Service together with any interest received.

          14. No Duty to Mitigate. Executive is not required to mitigate the
amount of salary or benefits payable pursuant to this Agreement upon termination
of his employment by seeking other employment or otherwise, nor shall any amount
provided to be paid by Employer pursuant to this Agreement upon termination of
Executive's employment be reduced by any compensation earned by Employee as a
result of employment by another employer that is not in violation of Executive's
obligations under Section 12.

          15. Severability. The invalidity or unenforceability of any provisions
of this Agreement shall not affect the validity or enforceability of any other
provisions of this Agreement, which shall remain in full force and effect.

          16. Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed to be an original but all of which
together shall constitute one and the same instrument.

          17. Resolution of Disputes. Employer agrees to pay promptly as
incurred, to the full extent permitted by law, all legal fees and expenses which
Executive may reasonably incur as a result of any contest, regardless of
outcome, by Employer, Executive 


                                       7

<PAGE>   8


or others of the validity of enforceability of, or liability under, any
provision of this Agreement or any guarantee of performance (including as a
result of any contest by Executive concerning the amount of any payment pursuant
to this Agreement).

          IN WITNESS WHEREOF, the parties hereto have executed this Agreement as
of the day and year first written above.

                              EMPLOYMENT AGREEMENT


                  THIS AGREEMENT, dated as of April 16, 1998, by and between AL

                  (b) Incentive Compensation. In addition to amounts paid to
         Executive as salary and for other benefits, Executive will participate
         in Employer's Executive Incentive Plan at a "partnership" rate of 15%
         of base salary for purposes of determining awards under the Plan. All
         amounts awarded are subject to the terms and conditions of the Plan.

                  (c) Benefit Plans. During the term of this agreement,
         Executive shall be entitled to participate, at a level commensurate
         with his position, in all benefit plans Employer presently has or

         limitation) pension, profit sharing, stock option or any group life or
         health insurance, hospitalization or other similar plans, any
         eligibility or waiting periods to be waived to the extent feasible.

                  (d) Life Insurance. Employer will purchase term life insurance
         coverage equal to two (2) times the initial Base Salary provided in

the performance of such duties.

                  5.  Termination by Employer; Death or Disability.

                  (a) With Cause. In the event the Board determines that
         Executive is guilty of gross dereliction of duty or of fraud or
         dishonesty in connection with the performance of his duties under this
         Agreement, the Board may terminate this Agreement such termination to
         be effective thirty (30) days after


                                       2

<PAGE>   3


         the Board gives written notice to Executive setting forth with
         specificity the reason or cause for terminating the Agreement. In such
         event, the compensation and other benefits provided for in this
         Agreement shall terminate on the date specified by the Board in the
         written notice of termination delivered to Executive.

                  (b) Without Cause. If Employer shall discharge Executive from
         his employment hereunder for any reason other than one set forth in
         Section 5(a), or if it shall be determined by a court of competent
         jurisdiction that the discharge under Section 5(a) was not justified,
         or if Employer violates the provisions of this Agreement in a material
         manner, Executive shall have the right to terminate his obligations and
         duties hereunder, but the rights of Executive to receive the
         compensation provided for in Section 3 shall continue nevertheless to
         be fully in effect for the remaining term of this Agreement in the same
         manner as would have been payable absent such termination.
         Notwithstanding the foregoing Employer shall have the right at any time
         after the termination contemplated by this Section 5(b) to pay
         Executive in a lump sum the then present value of the amount payable to
         Executive discounted at the then current savings rate for Bank under
         this Section (b).

                  (c) Death or Disability. This Agreement shall terminate in the
         event of the death or Disability of Executive.

                  6. Termination By Executive. Executive may, at any time upon
written notice to Employer, immediately terminate his employment for Good
Reason. For purposes of this Agreement, "Good Reason" shall mean any adverse
change in Executive's status or position as the President of 1st Source
Transportation Finance including, without limitation, as a result of a material
diminution of his duties or responsibilities or the assignment to him of duties
or responsibilities which, in his reasonable judgment, are inconsistent with
such status or positions, or any removal of Executive from, or any failure to
reappoint or reelect him to, any such position (except in connection with the
termination of his employment pursuant to Section 5(a) or 5(c) or by him for
other than Good Reason).

                  (a) If such termination does not follow a Change of Control of
         Employer or Bank, Executive shall continue to receive his Base Salary
         as then in effect for a period of twelve (12) months after the
         effective date of such termination, in the same manner as such Base
         Salary would have become payable pursuant to this Agreement absent such
         termination.

                  (b) If such termination occurs within one (1) year after a
         Change of Control of Employer or Bank, as severance pay and in lieu of
         any further


                                       3

<PAGE>   4


         compensation for periods subsequent to the effective date of such
         termination, Executive shall receive an amount in cash equal to 2.99
         times his "annualized includable compensation for the base period" (as
         defined in Section 280G(d)(1) of the Internal Revenue Code of 1986, as
         amended (the "Code")).

                  (c) Each of the events specified in the following clauses (i)
         through (iii) of this Section 6(c) shall be deemed a "Change in
         Control": (i) any third person, including a "group" within the meaning
         of Section 13(d)(3) of the Securities Exchange Act of 1934, shall
         become the beneficial owner of 50% or more of the then outstanding

                  11. Miscellaneous. No provision of this Agreement may be
modified, waived or discharged unless such waiver, modification or discharge is
agreed to in a writing signed by the parties hereto. No waiver by any party
hereto at any time of any breach by the other party hereto of, or compliance

at the same or at any prior or subsequent time.

                  12. Restrictive Covenants. In order to induce Employer to
enter into this Agreement, Executive hereby agrees as follows:

                  (a) While Executive is employed by Employer and for a period
         of twenty-four (24) months after the effective date of termination of
         such employment for reasons other than those set forth in Section 5(b)
         of this Agreement, Executive shall not divulge or furnish any trade
         secrets (as defined in IND. CODE ' 24-2-3-2) of Employer or any
         confidential information acquired by him while employed by Employer
         concerning the policies, plans, procedures or customers of Employer to
         any person, firm or corporation, other than Employer or with its prior
         written consent, or use any such trade secret or confidential
         information directly or indirectly for Executive's own benefit or for
         the benefit of any person, firm or corporation other than Employer, as
         such trade secrets and confidential information are confidential and
         shall at all times remain the property of Employer.

                  (b) For a period of twenty-four (24) months after the
         effective date of termination of Executive's employment hereunder for
         reasons other than those set forth in Section 5(b) of this Agreement,
         Executive shall not, directly or indirectly, provide banking or
         bank-related services to, or solicit the banking or bank-related
         business of, any customer of Employer at the time of such provision of
         services or solicitation which Employee served either alone or with
         others while employed by Employer within St. Joseph, Elkhart, Marshall
         or LaPorte Counties in the State of Indiana, or assist any actual or
         potential competitor of Employer to provide banking or bank-related
         services to, or solicit the banking or bank-related business of, any
         such customer in any such area, and Executive shall not, directly or
         indirectly, as principal, agent, or trustee, or through the agency of
         any corporation, partnership, trade association, agent or agency,
         engage in any banking or bank-related business or venture which
         competes with the business of Employer as conducted during Executive's
         employment by Employer within such area; provided, however, that
         Executive may own not more than five percent of the voting securities
         of any entity providing banking or bank-related services within such
         area if the


                                       5

<PAGE>   6


         voting securities of such entity are traded on a national securities
         exchange or quoted on a national interdealer quotation system.

                  (c) Executive acknowledges that any violation of this Section
         12 would cause irreparable harm to Employer, that damages for such harm
         would be incapable of precise measurement and that, accordingly,
         Employer would not have an adequate remedy at law to redress the harm
         caused by such violation. Therefore, Executive agrees that, in addition
         to any other remedy, Employer shall be entitled to immediate (i.e.,
         without prior notice) preliminary and final injunctive relief to enjoin
         and restrain any violation of this Section 12.

                  If Executive's employment is terminated during the Term of
this Agreement for reasons set forth in Section 5(b) of this Agreement,
Executive shall have no obligations to Employer with respect to trade secrets,
confidential information or noncompetition under this Section 12.

                  13. Certain Additional Payments by Employer.

                  (a) In the event that Section 280G of the Code is determined
         to apply to the payments to be made by Employer to Executive under this
         Agreement or other compensation or benefit programs, and in the event
         any excise tax ("Excise Tax") that may be imposed by Section 4999 of
         the Code become payable by Executive because of any of the payments
         made to Executive under this Agreement or otherwise, Employer will pay
         to Executive an additional amount ("Gross-up Payment") at least 60 days
         prior to the due date for payment of the Excise Tax. The Gross-up
         Payment shall be in an amount such that, after payment by Executive of
         all taxes (including, without limitation, all income and employment tax
         and Excise Tax and treating as a tax the disallowance of any deduction
         of Executive by virtue of the inclusion of the Gross-up Payment in
         Executive's adjusted gross income) and interest and penalties with
         respect to such taxes imposed upon the Gross-up Payment, Executive
         retains an amount equal to the Excise Tax. Employer shall notify
         Executive of its determination of the amount of payments under this
         Agreement subject to the Excise Tax (which determination shall be made
         by an accounting firm selected by Employer) and shall provide Executive
         with a receipt for the Excise Tax paid. Executive shall report the
         amount indicated in Employer's notice as the amount subject to the
         Excise Tax on Executive's Federal income tax return.



                                       6

<PAGE>   7


                  (b) If, for any reason, the Internal Revenue Service or any
         other taxing authority proposes an adjustment to the amount of Excise
         Tax due with respect to any payments or with respect to any additional
         amounts received by Executive pursuant to this Agreement, Executive
         will notify Employer immediately of such proposed adjustment and shall
         give Employer the right to contest such proposed adjustment on
         Executive's behalf; provided, however, that Executive may pay such
         claim if Employer does not take any action prior to the time such
         payment is due. Employer shall bear and pay directly all costs related
         to or associated with any contest, regardless of outcome, and shall
         have complete control over such contest as it relates to the Excise
         Tax, including whether such contest shall be by way of non-payment of
         the Excise Tax, payment of the Excise Tax under protest, or payment of
         the Excise Tax accompanied by a claim for a refund. Employer shall pay
         to Executive (i) an amount equal to the Excise Tax required to be paid
         to the Internal Revenue Service by Executive as a result of the outcome
         of any contest, any penalties or interest thereon, and (ii) a Gross-up
         Payment computed in the same manner and subject to the same adjustments
         as other Gross-up Payments previously described. Payment by Employer of
         an amount equal to the Excise tax and Gross-up Payment shall be made to
         Executive in advance of the due date for payment of Excise Taxes.

                  (c) In the event that the amount of any additional payments
         made pursuant to this Section 13 exceeds the amount determined to have
         been due, the excess additional amounts made shall constitute a loan by
         Employer to Executive payable within 30 days after receipt by Executive
         of the refund from the Internal Revenue Service together with any
         interest received.

                  14. No Duty to Mitigate. Executive is not required to mitigate
the amount of salary or benefits payable pursuant to this Agreement upon
termination of his employment by seeking other employment or otherwise, nor
shall any amount provided to be paid by Employer pursuant to this Agreement upon
termination of Executive's employment be reduced by any compensation earned by
Employee as a result of employment by another employer that is not in violation
of Executive's obligations under Section 12.

                  15. Severability. The invalidity or unenforceability of any
provisions of this Agreement shall not affect the validity or enforceability of
any other provisions of this Agreement, which shall remain in full force and
effect.

                  16. Counterparts. This Agreement may be executed in one or
more counterparts, each of which shall be deemed to be an original but all of
which together shall constitute one and the same instrument.



                                       7



<PAGE>   8


                  17. Resolution of Disputes. Employer agrees to pay promptly as
incurred, to the full extent permitted by law, all legal fees and expenses which
Executive may reasonably incur as a result of any contest, regardless of
outcome, by Employer, Executive or others of the validity of enforceability of,
or liability under, any provision of this Agreement or any guarantee of
performance (including as a result of any contest by Executive concerning the
amount of any payment pursuant to this Agreement).

                  IN WITNESS WHEREOF, the parties hereto have executed this
Agreement as of the day and year first written above.

                              EMPLOYMENT AGREEMENT


                  THIS AGREEMENT, dated as of April 16, 1998, by and between
LARRY E. LENTYCH, hereinafter referred to as "Executive", and lst SOURCE
CORPORATION, an Indiana corporation, hereinafter referred to as "Employer,"
WITNESSETH; That

                  WHEREAS, Executive is currently employed as an executive
officer of Employer and Employer's subsidiary, lst Source Bank, hereinafter
referred to as "Bank;" and

                  WHEREAS, Employer desires to assure the continued service of
Executive, and Executive is willing to provide such service on the terms and
conditions specified herein.

                  NOW THEREFORE, in consideration of the premises and the mutual
covenants and agreements contained in this Agreement, Employer and Executive
hereby agree as follows:

                  1. Employment Position. The parties agree that the employment
of Executive by Employer shall continue for the term referred to in Section 2.
Employer agrees to continue the employment of Executive in a senior officer

Executive shall devote his full time during business hours to the performance of
his duties hereunder and shall at all times use his best effort to promote the
best interests of Employer. Executive shall report to the Chief Executive
Officer of Employer, and/or the Chief Executive Officer of Bank.

                  2. Term. The term of this Agreement shall be from the date
hereof until December 31, 2001, unless terminated sooner in accordance with
Section 5 or Section 6 hereof, provided, however, that the term shall be
automatically extended for an additional year on January 1, 2002 and on January
1 of each year thereafter, unless either party hereto gives written notice of an
intention not to extend this Agreement on or before September 30 of the
preceding year, in which case no further automatic extension shall occur and the

<PAGE>   2

                  (b) Incentive Compensation. In addition to amounts paid to
         Executive as salary and for other benefits, Executive will participate
         in Employer's Executive Incentive Plan at a "partnership" rate of 15%
         of base salary for purposes of determining awards under the Plan. All
         amounts awarded are subject to the terms and conditions of the Plan.

                  (c) Benefit Plans. During the term of this agreement,
         Executive shall be entitled to participate, at a level commensurate
         with his position, in all benefit plans Employer presently has or
         hereafter adopts for its officers or employees, including (without
         limitation) pension, profit sharing, stock option or any group life or
         health insurance, hospitalization or other similar plans, any
         eligibility or waiting periods to be waived to the extent feasible.

                  (d) Life Insurance. Employer will purchase term life insurance
         coverage equal to two (2) times the initial Base Salary provided in
         Section 3(b) for the benefit of Executive, his family or estate as he
         may direct and as provided under Employer's insurance benefit programs.

                  (e) Club Membership. A club membership will be provided by
         Employer for Executive to at least one country club and to one club in
         downtown South Bend, Indiana, with the initiation fees, monthly fee and
         appropriate business related expenses paid by Employer.

                  4. Disability. In the event that this Agreement is terminated
by reason of Executive's Disability, Executive will continue to receive his Base
Salary for up to one year from the date of the termination and shall also
participate in any other disability compensation programs, including any Salary
Continuance Plan in effect at that time for officers or executives of Employer.
For purposes of this Agreement, "Disability" means Executive's inability by
reason of illness or other physical or mental impairment to perform the duties
required by his employment for any consecutive one hundred eighty (180) day
period, provided that written notice of any termination for Disability shall
have been given by Employer to Executive prior to the full resumption by him of
the performance of such duties.

                  5.       Termination by Employer; Death or Disability.

                  (a) With Cause. In the event the Board determines that
         Executive is guilty of gross dereliction of duty or of fraud or
         dishonesty in connection with the performance of his duties under this
         Agreement, the Board may terminate this Agreement such termination to
         be effective thirty (30) days after the Board gives written notice to
         Executive setting forth with specificity the 


                                       2

<PAGE>   3


         reason or cause for terminating the Agreement. In such event, the
         compensation and other benefits provided for in this Agreement shall
         terminate on the date specified by the Board in the written notice of
         termination delivered to Executive.

                  (b) Without Cause. If Employer shall discharge Executive from
         his employment hereunder for any reason other than one set forth in
         Section 5(a), or if it shall be determined by a court of competent
         jurisdiction that the discharge under Section 5(a) was not justified,
         or if Employer violates the provisions of this Agreement in a material
         manner, Executive shall have the right to terminate his obligations and
         duties hereunder, but the rights of Executive to receive the
         compensation provided for in Section 3 shall continue nevertheless to
         be fully in effect for the remaining term of this Agreement in the same
         manner as would have been payable absent such termination.
         Notwithstanding the foregoing Employer shall have the right at any time
         after the termination contemplated by this Section 5(b) to pay
         Executive in a lump sum the then present value of the amount payable to
         Executive discounted at the then current savings rate for Bank under
         this Section (b).

                  (c) Death or Disability. This Agreement shall terminate in the
         event of the death or Disability of Executive.

                  6. Termination By Executive. Executive may, at any time upon
written notice to Employer, immediately terminate his employment for Good
Reason. For purposes of this Agreement, "Good Reason" shall mean any adverse
change in Executive's status or position as Chief Financial Officer including,
without limitation, as a result of a material diminution of his duties or
responsibilities or the assignment to him of duties or responsibilities which,
in his reasonable judgment, are inconsistent with such status or positions, or
any removal of Executive from, or any failure to reappoint or reelect him to,
any such position (except in connection with the termination of his employment
pursuant to Section 5(a) or 5(c) or by him for other than Good Reason).

                  (a) If such termination does not follow a Change of Control of
         Employer or Bank, Executive shall continue to receive his Base Salary
         as then in effect for a period of twelve (12) months after the
         effective date of such termination, in the same manner as such Base
         Salary would have become payable pursuant to this Agreement absent such
         termination.

                  (b) If such termination occurs within one (1) year after a
         Change of Control of Employer or Bank, as severance pay and in lieu of
         any further compensation for periods subsequent to the effective date
         of such termination, 


                                       3


<PAGE>   4


         Executive shall receive an amount in cash equal to 2.99 times his
         "annualized includable compensation for the base period" (as defined in
         Section 280G(d)(1) of the Internal Revenue Code of 1986, as amended
         (the "Code")).

                  (c) Each of the events specified in the following clauses (i)
         through (iii) of this Section 6(c) shall be deemed a "Change in
         Control": (i) any third person, including a "group" within the meaning
         of Section 13(d)(3) of the Securities Exchange Act of 1934, shall
         become the beneficial owner of 50% or more of the then outstanding
         shares of common stock of Employer or the combined voting power of the
         then outstanding voting securities of Employer entitled to vote for the
         election of the Board of Directors of Employer (ii) as a result of, or
         in connection with, any cash tender offer, exchange offer, merger or
         other business combination, sale of assets or contested election, or
         combination of the foregoing, the persons who were directors of
         Employer shall cease to constitute a majority of such Board of
         Directors or (iii) the shareholders of Employer shall approve an
         agreement providing a sale or other disposition of all or substantially
         all the assets of Employer.

                  7. Assignment. This Agreement is a personal contract, and the
rights and interest of Executive hereunder may not be sold, transferred,
assigned, pledged or hypothecated. Except as otherwise may be herein expressly
provided, this Agreement shall inure to the benefit of and be binding upon
Employer and its successors and assigns.

                  8. Amendment. This Agreement may be amended only by a written
instrument signed by the parties hereto after approval by either the Board or
Executive Committee of Employer.

                  9. Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of Indiana.

                  10. Fees and Expenses. If a dispute arises regarding the
interpretation or enforcement of this Agreement and Executive obtains a final
judgment in his favor in a court of competent jurisdiction or his claim is
settled by Employer prior to the rendering of a judgment by such a court, all
reasonable legal fees and expenses incurred by Executive in seeking to obtain or
enforce any right or benefit provided for in this Agreement or otherwise
pursuing his claim shall be paid by Employer, to the fullest extent permitted by
law.

                  11. Miscellaneous. No provision of this Agreement may be
modified, waived or discharged unless such waiver, modification or discharge is
agreed to in a writing


                                       4

signed by the parties hereto. No waiver by any party hereto at any time of any
breach by the other party hereto of, or compliance with, any condition or
provision of this Agreement to be performed by such other party shall be deemed
a waiver of similar or dissimilar provisions or conditions at the same or at any
prior or subsequent time.

                  12. Restrictive Covenants. In order to induce Employer to
enter into this Agreement, Executive hereby agrees as follows:

                  (a) While Executive is employed by Employer and for a period
         of twenty-four (24) months after the effective date of termination of
         such employment for reasons other than those set forth in Section 5(b)
         of this Agreement, Executive shall not divulge or furnish any trade
         secrets (as defined in IND. CODE Section 24-2-3-2) of Employer or any
         confidential information acquired by him while employed by Employer
         concerning the policies, plans, procedures or customers of Employer to
         any person, firm or corporation, other than Employer or with its prior
         written consent, or use any such trade secret or confidential
         information directly or indirectly for Executive's own benefit or for
         the benefit of any person, firm or corporation other than Employer, as
         such trade secrets and confidential information are confidential and
         shall at all times remain the property of Employer.

                  (b) For a period of twenty-four (24) months after the
         effective date of termination of Executive's employment hereunder for
         reasons other than those set forth in Section 5(b) of this Agreement,
         Executive shall not, directly or indirectly, provide banking or
         bank-related services to, or solicit the banking or bank-related
         business of, any customer of Employer at the time of such provision of
         services or solicitation which Employee served either alone or with
         others while employed by Employer within St. Joseph, Elkhart, Marshall
         or LaPorte Counties in the State of Indiana, or assist any actual or
         potential competitor of Employer to provide banking or bank-related
         services to, or solicit the banking or bank-related business of, any
         such customer in any such area, and Executive shall not, directly or
         indirectly, as principal, agent, or trustee, or through the agency of
         any corporation, partnership, trade association, agent or agency,
         engage in any banking or bank-related business or venture which
         competes with the business of Employer as conducted during Executive's
         employment by Employer within such area; provided, however, that
         Executive may own not more than five percent of the voting securities
         of any entity providing banking or bank-related services within such
         area if the voting securities of such entity are traded on a national
         securities exchange or quoted on a national interdealer quotation
         system.

                  (c) Executive acknowledges that any violation of this Section
         12 would cause irreparable harm to Employer, that damages for such harm
         would be incapable of precise measurement and that, accordingly,
         Employer would not have an adequate remedy at law to redress the harm
         caused by such violation. Therefore, Executive agrees that, in addition
         to any other remedy, Employer shall be entitled to immediate (i.e.,
         without prior notice) preliminary and final injunctive relief to enjoin
         and restrain any violation of this Section 12.

                  If Executive's employment is terminated during the Term of
this Agreement for reasons set forth in Section 5(b) of this Agreement,
Executive shall have no obligations to Employer with respect to trade secrets,
confidential information or noncompetition under this Section 12.

                  13.      Certain Additional Payments by Employer.

                  (a) In the event that Section 280G of the Code is determined
         to apply to the payments to be made by Employer to Executive under this
         Agreement or other compensation or benefit programs, and in the event
         any excise tax ("Excise Tax") that may be imposed by Section 4999 of
         the Code become payable by Executive because of any of the payments
         made to Executive under this Agreement or otherwise, Employer will pay
         to Executive an additional amount ("Gross-up Payment") at least 60 days
         prior to the due date for payment of the Excise Tax. The Gross-up
         Payment shall be in an amount such that, after payment by Executive of
         all taxes (including, without limitation, all income and employment tax
         and Excise Tax and treating as a tax the disallowance of any deduction
         of Executive by virtue of the inclusion of the Gross-up Payment in
         Executive's adjusted gross income) and interest and penalties with
         respect to such taxes imposed upon the Gross-up Payment, Executive
         retains an amount equal to the Excise Tax. Employer shall notify
         Executive of its determination of the amount of payments under this
         Agreement subject to the Excise Tax (which determination shall be made
         by an accounting firm selected by Employer) and shall provide Executive
         with a receipt for the Excise Tax paid. Executive shall report the
         amount indicated in Employer's notice as the amount subject to the
         Excise Tax on Executive's Federal income tax return.

                  (b) If, for any reason, the Internal Revenue Service or any
         other taxing authority proposes an adjustment to the amount of Excise
         Tax due with respect to any payments or with respect to any additional
         amounts received by Executive pursuant to this Agreement, Executive
         will notify Employer


                                       6


<PAGE>   7


         immediately of such proposed adjustment and shall give Employer the
         right to contest such proposed adjustment on Executive's behalf;
         provided, however, that Executive may pay such claim if Employer does
         not take any action prior to the time such payment is due. Employer
         shall bear and pay directly all costs related to or associated with any
         contest, regardless of outcome, and shall have complete control over
         such contest as it relates to the Excise Tax, including whether such
         contest shall be by way of non-payment of the Excise Tax, payment of
         the Excise Tax under protest, or payment of the Excise Tax accompanied
         by a claim for a refund. Employer shall pay to Executive (i) an amount
         equal to the Excise Tax required to be paid to the Internal Revenue
         Service by Executive as a result of the outcome of any contest, any
         penalties or interest thereon, and (ii) a Gross-up Payment computed in
         the same manner and subject to the same adjustments as other Gross-up
         Payments previously described. Payment by Employer of an amount equal
         to the Excise tax and Gross-up Payment shall be made to Executive in
         advance of the due date for payment of Excise Taxes.

                  (c) In the event that the amount of any additional payments
         made pursuant to this Section 13 exceeds the amount determined to have
         been due, the excess additional amounts made shall constitute a loan by
         Employer to Executive payable within 30 days after receipt by Executive
         of the refund from the Internal Revenue Service together with any
         interest received.

                  14. No Duty to Mitigate. Executive is not required to mitigate
the amount of salary or benefits payable pursuant to this Agreement upon
termination of his employment by seeking other employment or otherwise, nor
shall any amount provided to be paid by Employer pursuant to this Agreement upon
termination of Executive's employment be reduced by any compensation earned by
Employee as a result of employment by another employer that is not in violation
of Executive's obligations under Section 12.

                  15. Severability. The invalidity or unenforceability of any
provisions of this Agreement shall not affect the validity or enforceability of
any other provisions of this Agreement, which shall remain in full force and
effect.

                  16. Counterparts. This Agreement may be executed in one or
more counterparts, each of which shall be deemed to be an original but all of
which together shall constitute one and the same instrument.

                  17. Resolution of Disputes. Employer agrees to pay promptly as
incurred, to the full extent permitted by law, all legal fees and expenses which
Executive may reasonably incur as a result of any contest, regardless of
outcome, by Employer, Executive


                                       7


<PAGE>   8

or others of the validity of enforceability of, or liability under, any
provision of this Agreement or any guarantee of performance (including as a
result of any contest by Executive concerning the amount of any payment pursuant
to this Agreement).

                  IN WITNESS WHEREOF, the parties hereto have executed this
Agreement as of the day and year first written above.

                              EMPLOYMENT AGREEMENT


                  THIS AGREEMENT, dated as of April 16, 1998, by and between
RICHARD STIFEL, hereinafter referred to as "Executive", and lst SOURCE
CORPORATION, an Indiana corporation, hereinafter referred to as "Employer,"
WITNESSETH; That

                  WHEREAS, Executive is currently employed as an executive
officer (currently Executive Vice President) of Employer's subsidiary, lst
Source Bank, hereinafter referred to as "Bank;" and

                  WHEREAS, Employer desires to assure the continued service of
Executive, and Executive is willing to provide such service on the terms and
conditions specified herein.

                  NOW THEREFORE, in consideration of the premises and the mutual
covenants and agreements contained in this Agreement, Employer and Executive
hereby agree as follows:

                  1. Employment Position. The parties agree that the employment
of Executive by Employer shall continue for the term referred to in Section 2.
Employer agrees to continue the employment of Executive in a senior officer
position with the title of Executive Vice President of Bank. Executive shall
devote his full time during business hours to the performance of his duties
hereunder and shall at all times use his best effort to promote the best
interests of Employer. Executive shall report to the President of Bank, or such
other senior executive officer of Employer or its subsidiary, 1st Source Bank,
as the Chief Executive Officer of Employer or the Board of Directors shall
direct.

                  2. Term. The term of this Agreement shall be from the date
hereof until December 31, 2001, unless terminated sooner in accordance with
Section 5 or Section 6 hereof, provided, however, that the term shall be
automatically extended for an additional year on January 1, 2002 and on January
1 of each year thereafter, unless either party hereto gives written notice of an
intention not to extend this Agreement on or before September 30 of the
preceding year, in which case no further automatic extension shall occur and the
term of this Agreement shall end.

                  3.       Compensation and Benefits.

                  (a) Base Salary. Executive shall be paid a Base Salary of One
         Hundred Sixty-Five Thousand Dollars ($165,000) per annum, with such
         increases thereafter as may be determined by Employer.



<PAGE>   2


                  (b) Incentive Compensation. In addition to amounts paid to
         Executive as salary and for other benefits, Executive will participate
         in Employer's Executive Incentive Plan at a "partnership" rate of 15%
         of base salary for purposes of determining awards under the Plan. All
         amounts awarded are subject to the terms and conditions of the Plan.

                  (c) Benefit Plans. During the term of this agreement,
         Executive shall be entitled to participate, at a level commensurate
         with his position, in all benefit plans Employer presently has or
         hereafter adopts for its officers or employees, including (without
         limitation) pension, profit sharing, stock option or any group life or
         health insurance, hospitalization or other similar plans, any
         eligibility or waiting periods to be waived to the extent feasible.

                  (d) Life Insurance. Employer will purchase term life insurance
         coverage equal to two (2) times the initial Base Salary provided in
         Section 3(b) for the benefit of Executive, his family or estate as he
         may direct and as provided under Employer's insurance benefit programs.

                  (e) Club Membership. A club membership will be provided by
         Employer for Executive to at least one country club and to one club in
         downtown South Bend, Indiana, with the initiation fees, monthly fee and
         appropriate business related expenses paid by Employer.

                  4. Disability. In the event that this Agreement is terminated
by reason of Executive's Disability, Executive will continue to receive his Base
Salary for up to one year from the date of the termination and shall also
participate in any other disability compensation programs, including any Salary
Continuance Plan in effect at that time for officers or executives of Employer.
For purposes of this Agreement, "Disability" means Executive's inability by
reason of illness or other physical or mental impairment to perform the duties
required by his employment for any consecutive one hundred eighty (180) day
period, provided that written notice of any termination for Disability shall
have been given by Employer to Executive prior to the full resumption by him of
the performance of such duties.

                  5.       Termination by Employer; Death or Disability.

                  (a) With Cause. In the event the Board determines that
         Executive is guilty of gross dereliction of duty or of fraud or
         dishonesty in connection with the performance of his duties under this
         Agreement, the Board may terminate this Agreement such termination to
         be effective thirty (30) days after the Board gives written notice to
         Executive setting forth with specificity the



                                       2

<PAGE>   3


         reason or cause for terminating the Agreement. In such event, the
         compensation and other benefits provided for in this Agreement shall
         terminate on the date specified by the Board in the written notice of
         termination delivered to Executive.

                  (b) Without Cause. If Employer shall discharge Executive from
         his employment hereunder for any reason other than one set forth in
         Section 5(a), or if it shall be determined by a court of competent
         jurisdiction that the discharge under Section 5(a) was not justified,
         or if Employer violates the provisions of this Agreement in a material
         manner, Executive shall have the right to terminate his obligations and
         duties hereunder, but the rights of Executive to receive the
         compensation provided for in Section 3 shall continue nevertheless to
         be fully in effect for the remaining term of this Agreement in the same
         manner as would have been payable absent such termination.
         Notwithstanding the foregoing Employer shall have the right at any time
         after the termination contemplated by this Section 5(b) to pay
         Executive in a lump sum the then present value of the amount payable to
         Executive discounted at the then current savings rate for Bank under
         this Section (b).

                  (c) Death or Disability. This Agreement shall terminate in the
         event of the death or Disability of Executive.

                  6. Termination By Executive. Executive may, at any time upon
written notice to Employer, immediately terminate his employment for Good
Reason. For purposes of this Agreement, "Good Reason" shall mean any adverse
change in Executive's status or position as the Executive Vice President of Bank
including, without limitation, as a result of a material diminution of his
duties or responsibilities or the assignment to him of duties or
responsibilities which, in his reasonable judgment, are inconsistent with such
status or positions, or any removal of Executive from, or any failure to
reappoint or reelect him to, any such position (except in connection with the
termination of his employment pursuant to Section 5(a) or 5(c) or by him for
other than Good Reason).

                  (a) If such termination does not follow a Change of Control of
         Employer or Bank, Executive shall continue to receive his Base Salary
         as then in effect for a period of twelve (12) months after the
         effective date of such termination, in the same manner as such Base
         Salary would have become payable pursuant to this Agreement absent such
         termination.

                  (b) If such termination occurs within one (1) year after a
         Change of Control of Employer or Bank, as severance pay and in lieu of
         any further compensation for periods subsequent to the effective date
         of such termination,


                                       3


<PAGE>   4


         Executive shall receive an amount in cash equal to 2.99 times his
         "annualized includable compensation for the base period" (as defined in
         Section 280G(d)(1) of the Internal Revenue Code of 1986, as amended
         (the "Code")).

                  (c) Each of the events specified in the following clauses (i)
         through (iii) of this Section 6(c) shall be deemed a "Change in
         Control": (i) any third person, including a "group" within the meaning
         of Section 13(d)(3) of the Securities Exchange Act of 1934, shall
         become the beneficial owner of 50% or more of the then outstanding
         shares of common stock of Employer or the combined voting power of the
         then outstanding voting securities of Employer entitled to vote for the
         election of the Board of Directors of Employer (ii) as a result of, or
         in connection with, any cash tender offer, exchange offer, merger or
         other business combination, sale of assets or contested election, or
         combination of the foregoing, the persons who were directors of
         Employer shall cease to constitute a majority of such Board of
         Directors or (iii) the shareholders of Employer shall approve an
         agreement providing a sale or other disposition of all or substantially
         all the assets of Employer.

                  7. Assignment. This Agreement is a personal contract, and the
rights and interest of Executive hereunder may not be sold, transferred,
assigned, pledged or hypothecated. Except as otherwise may be herein expressly
provided, this Agreement shall inure to the benefit of and be binding upon
Employer and its successors and assigns.

                  8. Amendment. This Agreement may be amended only by a written
instrument signed by the parties hereto after approval by either the Board or
Executive Committee of Employer.

                  9. Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of Indiana.

                  10. Fees and Expenses. If a dispute arises regarding the
interpretation or enforcement of this Agreement and Executive obtains a final
judgment in his favor in a court of competent jurisdiction or his claim is
settled by Employer prior to the rendering of a judgment by such a court, all
reasonable legal fees and expenses incurred by Executive in seeking to obtain or
enforce any right or benefit provided for in this Agreement or otherwise
pursuing his claim shall be paid by Employer, to the fullest extent permitted by
law.

                  11. Miscellaneous. No provision of this Agreement may be
modified, waived or discharged unless such waiver, modification or discharge is
agreed to in a writing 


                                       4


<PAGE>   5



signed by the parties hereto. No waiver by any party hereto at any time of any
breach by the other party hereto of, or compliance with, any condition or
provision of this Agreement to be performed by such other party shall be deemed
a waiver of similar or dissimilar provisions or conditions at the same or at any
prior or subsequent time.

                  12. Restrictive Covenants. In order to induce Employer to
enter into this Agreement, Executive hereby agrees as follows:

                  (a) While Executive is employed by Employer and for a period
         of twenty-four (24) months after the effective date of termination of
         such employment for reasons other than those set forth in Section 5(b)
         of this Agreement, Executive shall not divulge or furnish any trade
         secrets (as defined in IND. CODE Section 24-2-3-2) of Employer or any
         confidential information acquired by him while employed by Employer
         concerning the policies, plans, procedures or customers of Employer to
         any person, firm or corporation, other than Employer or with its prior
         written consent, or use any such trade secret or confidential
         information directly or indirectly for Executive's own benefit or for
         the benefit of any person, firm or corporation other than Employer, as
         such trade secrets and confidential information are confidential and
         shall at all times remain the property of Employer.

                  (b) For a period of twenty-four (24) months after the
         effective date of termination of Executive's employment hereunder for
         reasons other than those set forth in Section 5(b) of this Agreement,
         Executive shall not, directly or indirectly, provide banking or
         bank-related services to, or solicit the banking or bank-related
         business of, any customer of Employer at the time of such provision of
         services or solicitation which Employee served either alone or with
         others while employed by Employer within St. Joseph, Elkhart, Marshall
         or LaPorte Counties in the State of Indiana, or assist any actual or
         potential competitor of Employer to provide banking or bank-related
         services to, or solicit the banking or bank-related business of, any
         such customer in any such area, and Executive shall not, directly or
         indirectly, as principal, agent, or trustee, or through the agency of
         any corporation, partnership, trade association, agent or agency,
         engage in any banking or bank-related business or venture which
         competes with the business of Employer as conducted during Executive's
         employment by Employer within such area; provided, however, that
         Executive may own not more than five percent of the voting securities
         of any entity providing banking or bank-related services within such
         area if the voting securities of such entity are traded on a national
         securities exchange or quoted on a national interdealer quotation
         system.

                 (c) Executive acknowledges that any violation of this Section
         12 would cause irreparable harm to Employer, that damages for such harm
         would be incapable of precise measurement and that, accordingly,
         Employer would not have an adequate remedy at law to redress the harm
         caused by such violation. Therefore, Executive agrees that, in addition
         to any other remedy, Employer shall be entitled to immediate (i.e.,
         without prior notice) preliminary and final injunctive relief to enjoin
         and restrain any violation of this Section 12.

                  If Executive's employment is terminated during the Term of
this Agreement for reasons set forth in Section 5(b) of this Agreement,
Executive shall have no obligations to Employer with respect to trade secrets,
confidential information or noncompetition under this Section 12.

                  13.      Certain Additional Payments by Employer.

                  (a) In the event that Section 280G of the Code is determined
         to apply to the payments to be made by Employer to Executive under this
         Agreement or other compensation or benefit programs, and in the event
         any excise tax ("Excise Tax") that may be imposed by Section 4999 of
         the Code become payable by Executive because of any of the payments
         made to Executive under this Agreement or otherwise, Employer will pay
         to Executive an additional amount ("Gross-up Payment") at least 60 days
         prior to the due date for payment of the Excise Tax. The Gross-up
         Payment shall be in an amount such that, after payment by Executive of
         all taxes (including, without limitation, all income and employment tax
         and Excise Tax and treating as a tax the disallowance of any deduction
         of Executive by virtue of the inclusion of the Gross-up Payment in
         Executive's adjusted gross income) and interest and penalties with
         respect to such taxes imposed upon the Gross-up Payment, Executive
         retains an amount equal to the Excise Tax. Employer shall notify
         Executive of its determination of the amount of payments under this
         Agreement subject to the Excise Tax (which determination shall be made
         by an accounting firm selected by Employer) and shall provide Executive
         with a receipt for the Excise Tax paid. Executive shall report the
         amount indicated in Employer's notice as the amount subject to the
         Excise Tax on Executive's Federal income tax return.

                  (b) If, for any reason, the Internal Revenue Service or any
         other taxing authority proposes an adjustment to the amount of Excise
         Tax due with respect to any payments or with respect to any additional
         amounts received by Executive pursuant to this Agreement, Executive
         will notify Employer


                                       6


<PAGE>   7


         immediately of such proposed adjustment and shall give Employer the
         right to contest such proposed adjustment on Executive's behalf;
         provided, however, that Executive may pay such claim if Employer does
         not take any action prior to the time such payment is due. Employer
         shall bear and pay directly all costs related to or associated with any
         contest, regardless of outcome, and shall have complete control over
         such contest as it relates to the Excise Tax, including whether such
         contest shall be by way of non-payment of the Excise Tax, payment of
         the Excise Tax under protest, or payment of the Excise Tax accompanied
         by a claim for a refund. Employer shall pay to Executive (i) an amount
         equal to the Excise Tax required to be paid to the Internal Revenue
         Service by Executive as a result of the outcome of any contest, any
         penalties or interest thereon, and (ii) a Gross-up Payment computed in
         the same manner and subject to the same adjustments as other Gross-up
         Payments previously described. Payment by Employer of an amount equal
         to the Excise tax and Gross-up Payment shall be made to Executive in
         advance of the due date for payment of Excise Taxes.

                  (c) In the event that the amount of any additional payments
         made pursuant to this Section 13 exceeds the amount determined to have
         been due, the excess additional amounts made shall constitute a loan by
         Employer to Executive payable within 30 days after receipt by Executive
         of the refund from the Internal Revenue Service together with any
         interest received.

                  14. No Duty to Mitigate. Executive is not required to mitigate
the amount of salary or benefits payable pursuant to this Agreement upon
termination of his employment by seeking other employment or otherwise, nor
shall any amount provided to be paid by Employer pursuant to this Agreement upon
termination of Executive's employment be reduced by any compensation earned by
Employee as a result of employment by another employer that is not in violation
of Executive's obligations under Section 12.

                  15. Severability. The invalidity or unenforceability of any
provisions of this Agreement shall not affect the validity or enforceability of
any other provisions of this Agreement, which shall remain in full force and
effect.

                  16. Counterparts. This Agreement may be executed in one or
more counterparts, each of which shall be deemed to be an original but all of
which together shall constitute one and the same instrument.

                  17. Resolution of Disputes. Employer agrees to pay promptly as
incurred, to the full extent permitted by law, all legal fees and expenses which
Executive may reasonably incur as a result of any contest, regardless of
outcome, by Employer, Executive 


                                       7

or others of the validity of enforceability of, or liability under, any
provision of this Agreement or any guarantee of performance (including as a
result of any contest by Executive concerning the amount of any payment pursuant
to this Agreement).

                  IN WITNESS WHEREOF, the parties hereto have executed this
Agreement as of the day and year first written above.

                             1ST SOURCE CORPORATION
                       1998 PERFORMANCE COMPENSATION PLAN

                                    SECTION 1
                                     PURPOSE

  The purpose of the 1st Source Corporation ("Company") 1998 Performance
Compensation Plan ("Plan") is to promote the interests of the Company and its
shareholders through the (i) attraction and retention of executive officers and
other key employees ("Employees") essential to the success of the Company and
its subsidiaries; (ii) motivation of Employees using performance-related
incentives linked to longer range performance goals and the interests of Company
shareholders; and (iii) enabling of the Employees to share in the long term
growth and success of the Company.

                                    SECTION 2
                                 ADMINISTRATION

  The Plan will be administered by the Executive Compensation Committee
("Committee") of the Board of Directors of the Company, which will consist of
two or more members.

  The Committee will have the sole, final and conclusive authority to
administer, construe and interpret the Plan. All members of the Committee must
be non-employee, outside directors as defined in applicable IRS Regulations.

                                    SECTION 3
                                   ELIGIBILITY

  The Committee in its sole and complete discretion will select full-time
Employees of the Company and its subsidiaries, who in its opinion, can
contribute significantly to the growth and profitability of, or perform services
of major importance to, the Company and its subsidiaries. No non-employee
director of the Company will be eligible to participate under the Plan. No
member of the Committee will be eligible to participate under the Plan.

                                    SECTION 4
                                GRANTS AND AWARDS

  Any awards made to Employees under the Plan will be performance-based
compensation ("Awards") subject to the attainment of pre-established objective
performance goals, including one or more of the following criteria: (i) net
income; (ii) pre-tax income; (iii) earnings per share; (iv) return on 



<PAGE>   2


equity; (v) return on assets; (vi) Economic Value Added and/or increase in
Economic Value Added; (vii) increase in the market price of the Company's common
stock; (viii) total shareholder return (stock price appreciation plus
dividends); and (ix) the performance of the Company in any of the items
mentioned in clauses (i) through (viii) in comparison to the average performance
of companies combined into a Company-constructed peer group.

  All performance measures, formulas and determination of eligibility for a
performance period will be established by the Committee in writing no later than
ninety (90) days after the beginning of the performance period or by such other
date as may be permitted under Section 162(m) of the Internal Revenue Code of
1986 and the regulations. Performance measures may be based on one or more of
the business criteria listed herein. No Award to any single Employee will exceed
$5 million in one calendar year. No performance measures will allow for any
discretion by the Committee to increase any Award, but discretion to lower
Awards is permissible. The payment of any Award under the Plan to an Employee
with respect to a relevant performance period will be contingent upon
certification by the Committee prior to any such payment that the applicable
performance measure(s) relating to the Award have been satisfied. Payment of the
award will not be conditioned upon it being deductible by the Company.
Notwithstanding any other provision of the Plan, the Committee may impose such
conditions on any Award, and the Board may amend the plan in any such respects,
as may be required to satisfy the requirements of Section 162(m) of the Internal
Revenue Code (or any successor or similar rule relating thereto).

  If an Employee's employment with the Company is terminated by reason of death
or total and permanent disability that occurs before the end of a Performance
Period, the Employee will be entitled to a pro rata award based upon the number
of days elapsed at the time of termination. The amount of any Award due a
deceased Employee will be paid to the beneficiary designated by the Employee in
writing to the Company, or if none, the Employee's Estate.

                                    SECTION 5
                             NO EMPLOYMENT CONTRACT

  The Plan is not and is not intended to be an employment contract with respect
to any of the Employees, and the Company's rights to continue or to terminate
the employment relationship of any Employee will not be affected by the Plan.

                                    SECTION 6
                            AMENDMENT AND TERMINATION

  The Board of Directors of the Company may amend, suspend or terminate the Plan
or any portion thereof at any time, but it may not adversely affect the


<PAGE>   3


rights of any Employee under an award.  Any material amendment will require
shareholder approval.

                                    SECTION 7
                                    INDEMNITY

any loss, cost, liability, or expense that may be imposed upon or reasonably
incurred in connection with or resulting from any claim, action, suit, or
proceeding to which such person may be a party or in which they may be involved
by reason of any action taken or failure to act under the Plan and against and
from any and all amounts paid by such persons in settlement thereof with the
Company's approval, or paid in satisfaction of a judgment in any such action,
suit or proceeding against them, provided they will give the Company an
opportunity, at its own expense, to handle and defend the same before they
undertake to handle and defend it on their behalf. The foregoing right of
indemnification will not be exclusive of any other rights of indemnification to
which such persons may be entitled under the Company Articles of Incorporation
or Code of By-Laws, as a matter of law, or otherwise, or any power that the
Company may have to indemnify them or hold them harmless.

                                    SECTION 8
                                EXPENSES OF PLAN


  The expenses of administering the Plan will be borne by the Company.

                                    SECTION 9
                                   SUCCESSORS

  The Plan will be binding upon the successors and assigns of the Company.

                                   SECTION 10
                                 TAX WITHHOLDING

  The Plan, and its rules, rights, agreements and regulations, will be


<PAGE>   4


governed, construed, interpreted and administered solely in accordance with the
laws of the State of Indiana. In the event any provision of the Plan will be
held invalid, illegal or unenforceable, in whole or in part, for any reason,
such determination will not affect the validity, legality or enforceability of
any remaining provision, portion of provision or Plan overall, which will remain
in full force and effect as if the Plan has been absent the invalid, illegal or
unenforceable provision or portion thereof.

  Unless otherwise specifically provided herein, any notice to be given to the
Committee under the Plan will be given in writing and will be deemed delivered
for all purposes of the Plan if personally delivered to a member of the
Committee or mailed to such Committee addressed to the Company by postpaid,
certified United States mail.

                                   SECTION 12

  The Plan was adopted on February 19, 1998, by the Executive Committee of the
Board of Directors of the Company and will be effective as of that date, subject

                              CONSULTING AGREEMENT


                  This CONSULTING AGREEMENT (the "Agreement") is entered into
this 14th day of April, 1998, between ERNESTINE M. RACLIN ("Raclin") and 1ST

                  A. Effective April 16, 1998, Ernestine M. Raclin is retiring
after long and distinguished service as Chairman of the Board of 1ST Source and
its bank subsidiary.

                  B. Because Raclin possesses valuable experience, knowledge,
and expertise concerning the operations, customers, markets, business plans, and
other matters of vital importance to 1ST Source and its subsidiaries, 1ST Source
desires to ensure its continued and exclusive access to that experience,
knowledge, and expertise by entering into a consulting arrangement with her.

1ST Source.

                  D. 1ST Source and Raclin desire to set forth in writing the
terms and conditions of the consulting relationship.

                                    AGREEMENT

                  In consideration of the premises and the following mutual
undertakings, the parties agree as follows:

                  1. Consulting Relationship. Effective April 16, 1998, Raclin
shall provide consulting services to 1ST Source under the terms of this
Agreement.

                  2. Term. Raclin's consulting relationship under this Agreement
shall commence as of April 16, 1998, and shall continue through April 15, 2008,
unless and until otherwise terminated pursuant to Paragraph 6 (the "Term").

                  3.       Responsibilities of Raclin.

                           3.1 Consultant. As requested by 1ST Source, Raclin,

                  Directors and executive officers of 1ST Source, to foster
                  existing and potential customer relationships for the benefit
                  of



<PAGE>   2


                  1ST Source, to represent the interests of 1ST Source in civic,
                  banking, and other business organizations, and otherwise to
                  make available her experience, knowledge, and expertise for
                  the benefit of 1ST Source. Raclin shall be available to
                  provide up to 400 hours of service per calendar year under the
                  terms of this Agreement.

                  services under this Agreement as an independent contractor.
                  Except as otherwise provided in this Agreement, she shall have
                  the sole discretion and responsibility for the selection of
                  procedures, processes, personnel, materials, working hours,
                  and other incidents of performance of services. So long as
                  Raclin performs services in accordance with this Agreement and
                  complies with the restrictive covenants of Paragraph 7,
                  nothing shall prevent her from performing services for other
                  noncompeting businesses or entities.

                           3.3 Taxes. Raclin shall be solely responsible for all
                  tax obligations with respect to consulting fees received under

                  responsibilities shall be assigned, from time to time, by the
                  Chairman and Chief Executive Officer of 1ST Source. Except as
                  expressly provided by the terms of a particular assignment,
                  Raclin shall not have the authority to bind 1ST Source.

                  4.       Consulting Fees and Support Services. For the first 
five years of the Term, Raclin shall receive an annual consulting fee of
$150,000, payable monthly or as the parties may from time to time agree; for the

                  suite and clerical services.



                                       2


<PAGE>   3


                           4.2 Other Support Services. To assist her in
                  performing consulting services under this Agreement, 1ST
                  Source shall make available to Raclin the use of its corporate
                  aircraft for up to 50 hours per calendar year. 1ST Source
                  shall also provide, at its expense, memberships in one country
                  club and one business club located in the area of South Bend,
                  Indiana, or other geographic area in which a membership can
                  reasonably be used for the benefit of 1ST Source.

                           4.3 Expense Reimbursement. 1ST Source shall reimburse
                  Raclin for reasonable and necessary business and travel and
                  entertainment expenses that she incurs in performing
                  consulting services under this Agreement.

                           4.4 Medical/Physical Exam. 1ST Source shall reimburse
                  Raclin for the monthly insurance premiums required for the
                  purchase of Medicare supplemental insurance Plan J and shall
                  also reimburse Raclin for her annual physical conducted at the
                  Mayo Clinic or such other comparable diagnostic facility for
                  the period of this Agreement.

                  5.       Deferral of Fees. In Raclin's discretion, she may 
elect to defer the payment of all or a portion of the consulting fees that she
is to receive under this Agreement, according to the following procedures:

                           5.1 Election. To defer fees to be earned during a
                  calendar year, Raclin shall deliver a written deferral
                  election to 1ST Source before the beginning of that calendar
                  year. For the period from April 16, 1998, through December 31,
                  1998, however, Raclin may make such an election before the
                  beginning of that period. Each election shall be irrevocable
                  and shall designate the amount to be deferred and the date the
                  deferred amounts are to be paid.

                           5.2 Account. 1ST Source shall maintain an individual
                  bookkeeping account in Raclin's name on the accounting records
                  of 1ST Source. The account shall be credited monthly with the
                  amount of Raclin's deferrals, as well as earnings at 1ST
                  Source Bank's current prime lending rate.

<PAGE>   4


                           5.3 Unfunded Status. The obligation of 1ST Source to
                  pay the deferred fees is only a contractual obligation to make
                  payments when due. The obligation shall not be secured, and
                  1ST Source shall not set aside assets beyond the reach of its
                  general creditors for the purpose of paying the deferred fees.

                           5.4 Payment of Deferred Fees. The account balance
                  shall be paid in a lump sum payment to Raclin (or, in the
                  event of her death, to her beneficiary) upon the earlier of
                  the date designated by her written election or the termination
                  of the consulting relationship under Paragraph 6. In
                  accordance with procedures prescribed by 1ST Source, Raclin
                  may designate as beneficiary the person or persons, including
                  a trustee, to receive the balance of her account in the event
                  of her death. If no beneficiary has been designated or if no
                  designated beneficiary survives Raclin, her beneficiary shall
                  be her estate.

                           5.5 Transferability. Neither Raclin nor her
                  beneficiary shall have the power to transfer, pledge, or
                  otherwise encumber any of the deferred fees due under this
                  Agreement, and any attempt to do so shall be void. Any rights
                  to deferred fees under this Agreement shall not be subject to
                  attachment, garnishment, execution, or other transfer by
                  operation of law in the event of bankruptcy, insolvency, or

                  responsibilities under this Agreement by reason of physical or
                  mental condition for a period of at least 365 consecutive
                  days, as reasonably determined by 1ST Source.

                           6.3 Termination for Cause. Termination of Raclin's
                  consulting relationship by 1ST Source for cause. For purposes

<PAGE>   5
                  of this Agreement, "cause" shall mean solely (i) conviction of
                  a felony or a lesser crime, which lesser crime results in
                  injury to the business, reputation or property of 1ST Source,
                  (ii) material acts of malfeasance in the performance of
                  Raclin's duties, including misuse or diversion of 1ST Source
                  funds or willful and material misrepresentations or
                  concealments on any reports submitted to 1ST Source, or (iii)
                  material breach of this Agreement.

                           6.4 Termination Not for Cause. Termination of
                  Raclin's consulting relationship by 1ST Source for reasons
                  that do not constitute cause.

                           6.5 Resignation. Termination of Raclin's consulting
                  relationship voluntarily by Raclin.

                           6.6 Accrual of Fees Through Termination. Upon
                  termination of Raclin's consulting relationship under
                  Paragraph 6.3 or 6.5, Raclin's accrual of fees shall cease as
                  of the date of the termination. Upon termination of Raclin's
                  consulting relationship under Paragraph 6.4, Raclin's accrual
                  of fees shall continue through April 15, 2008. Upon
                  termination of Raclin's consulting relationship under other
                  circumstances, Raclin's accrual of fees shall cease as of the
                  end of the year in which the termination occurs.

                  7. Restrictive Covenants. In connection with Raclin's
consulting relationship, Raclin will become acquainted with 1ST Source's
services, products, business practices, current and prospective customers and
their requirements, trade secrets, and other information that is not generally
known or readily ascertainable by others (collectively, the "Confidential
Information") and will develop business relationships with employees, customers,
and potential customers of 1ST Source and its subsidiaries. Therefore, as an
essential ingredient and consideration of this Agreement, Raclin enters into the
following covenants:

                           7.1 Confidential Information. Raclin shall use the
                  Confidential Information only in the course of her duties as a
                  consultant to 1ST Source, and she shall not disclose, during
                  or at any time after the term of her consulting relationship,
                  any Confidential Information to anyone except as authorized by
                  1ST Source.



                                       5

 
<PAGE>   6


                          7.2 Corporation Records. Raclin agrees that all
                  records of 1ST Source containing or referring to Confidential
                  Information are the sole property of 1ST Source. Raclin shall
                  keep those records subject to 1ST Source's custody and control
                  and shall return them promptly to 1ST Source at the
                  termination of her consulting services, without retaining any
                  copies or notes of those records.

                           7.3 Competition. During the term of Raclin's
                  consulting relationship and for the period of two (2) years
                  after her consulting relationship terminates for any reason,
                  Raclin shall not directly or indirectly - whether as an
                  individual, employee, sole proprietor, partner, corporate
                  shareholder, officer, director, agent, consultant, formal or
                  informal advisor or by lending any other form of assistance -
                  do any of the following:

                           (a) Engage in any activity that is in material
                  competition with the business of 1ST Source or any of its
                  subsidiaries;

                           (b) Solicit, assist others in soliciting, or engage
                  in any other effort to obtain for any entity other than 1ST
                  Source the business of any customer with whom 1ST Source did
                  business at any time during the one (1) year period
                  immediately preceding the termination of Raclin's consulting
                  relationship; or

                           (c) Hire away, attempt to hire away, or assist in the
                  departure from employment from 1ST Source of any person who
                  was an employee of 1ST Source at the time of the termination
                  of Raclin's consulting arrangement with 1ST Source.

These covenants supplement, and do not supersede, the provisions of the Indiana
Uniform Trade Secrets Act and the duties Raclin owes to 1ST Source under common
law.

                  8.       Enforcement of Restrictive Covenants. Raclin agrees 
that any violation by Raclin of any provision of Paragraph 7 of this Agreement
will cause 1ST Source to suffer irreparable harm, that damages for such harm
will be incapable of precise measurement, and that 1ST Source will therefore not
have an adequate remedy at 


                                       6


<PAGE>   7


law to redress the violation. Therefore, if Raclin violates or threatens to
violate any provision of that Paragraph, 1ST Source shall be entitled, in
addition to its other remedies, to temporary restraining orders and preliminary
and permanent injunctions to restrain and enjoin any violation or threatened
violation of this Agreement. Raclin waives any right to raise questions of
personal jurisdiction or venue in any action 1ST Source may bring against Raclin
in any state or federal court in the county where a violation occurs or is
threatened to occur. In addition to the other relief to which it shall be
entitled, 1ST Source shall be entitled to recover from Raclin its costs and
reasonable attorneys' fees incurred by 1ST Source in seeking enforcement of this
Agreement.

                  9. Separability. Should any clause, portion or paragraph of
this Agreement be unenforceable or invalid for any reason, that shall not affect
the enforceability or validity of the remainder of this Agreement. Should any
particular provision or restriction including, but not limited to, the covenants
and restrictions of Paragraph 7, be held to be unreasonable or unenforceable for
any reason, including the time period, geographical area or scope of activity
covered by the covenant or restriction, then that covenant or restriction shall
be given effect and enforced to whatever extent would be reasonable and
enforceable.

                  10. Notices. All notices and other communications required or
permitted under this Agreement shall be in writing and shall be deemed to have
been properly given if delivered by hand, sent by telecopy, or mailed, certified
or registered mail with postage and fees prepaid:




                  If to 1ST Source, to:            Vincent A. Tamburo, Secretary

                  If to Raclin, to:                Ernestine M. Raclin
                                                   110 N. Esther Steet
                                                   South Bend, Indiana 46617

or to such other person or address as the party to whom such notice or
communication is to be given shall have notified the other party in accordance
with this Paragraph. Any mailed communication shall be deemed to have been given
on the third "business day" (such term excluding, for purposes of this
Agreement, Saturdays, Sundays, and legal holidays) after the day of mailing. Any
communication sent by telecopy shall be deemed



                                       7

<PAGE>   8
 

to have been given on the date receipt of the telecopy transmission is confirmed
by telecopy; provided, that if any communication sent by telecopy is also mailed
by certified mail, return receipt requested, in accordance with this Paragraph,
such communication shall be deemed to have been given on the date receipt of the
telecopy transmission is confirmed by telecopy or the third business day after
the day of mailing, whichever is earlier.

                  11. Successors and Assigns. 1ST Source shall require any
successor (whether direct or indirect, by purchase, merger, consolidation or
otherwise) to all or substantially all of the business or assets of 1ST Source,
by agreement in form and substance satisfactory to Raclin, to expressly assume
and agree to perform this Agreement in the same manner and to the same extent
that 1ST Source would be required to perform it if no such succession had taken
place. Failure of 1ST Source to obtain such agreement prior to the effectiveness
of any such succession shall be a breach of this Agreement and shall entitle
Raclin to consulting fees from 1ST Source under Paragraph 4 and its
subparagraphs for the remaining Term. As used in this Paragraph, "1ST Source"
shall mean 1ST Source Corporation and any successor to its business or assets.

                  12. Oral Modifications Not Binding. This Agreement may not be
modified or terminated orally. No modification, termination or attempted waiver
shall be valid unless in writing signed by the party against whom it is sought
to be enforced.

                  13. Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of Indiana.

                  14. Entire Agreement. With respect to the subject matter
hereof, this Agreement sets forth the entire agreement of the parties and
supersedes all prior agreements, representations or communications between them,
whether written or oral.

                  15. Counterparts. This Agreement may be executed in one or
more counterparts, each of which shall be deemed to be an original and all of
which taken together shall constitute one and the same instrument.

                  The parties have executed this Agreement on the date and year
first written above.

17.1% higher than the $26.5 million earned in 1997. Adjusting for a 10% stock

TO OUR SHAREHOLDERS:
   1998 was a year of both continued good performance and change. By pursuing
our original Vision 2000 goals defined in 1995, we realized growth and record
earnings. For the year, our net income was up 17.1 percent over last year to
$31,020,000, with diluted net income per common share up 17.6 percent to $1.60.
The banking centers opened over the last few years performed well, leading us to
expect the same from the two branches we established in new markets in 1998. New
investment products and services were introduced by our Personal Wealth
Management Division. We also reorganized our reporting structures to ensure
continued management development through more direct authority and
accountability. We experienced record-setting growth in mortgage production at
both 1st Source Bank and at our mortgage company subsidiary, Trustcorp Mortgage.
Growth of our specialty finance businesses continued with the addition of sales
representatives in new markets and an increase in securitized loans in the
aircraft and auto finance industries. Substantial progress too was made in
ensuring that all our mission-critical operating and business systems are Year
2000 compliant; we expect few, if any, problems at the turn of the century.

   Before outlining in greater detail the results of the past year and the
issues to be addressed in the coming one, I want to recognize and thank an
extraordinary woman, Ernestine Raclin, who retired as Chairman of the Board at
our Annual Meeting in April. For the last 20 years we have been signing this
shareholders' letter together. As Chairman of 1st Source she set a standard and
an example that ennobles us and challenges all of us to do our very best for all
of the constituencies we serve. She committed us to independence when others
were selling out, and to high performance for the benefit of our shareholders
and the community. She has imbued 1st Source with positive values, a family
atmosphere, and a commitment to service. As a result, and in tribute, we have
dedicated this Annual Report to her and have recently established the Ernestine
M. Raclin Community Leadership Awards to continue her legacy of a working
commitment to the communities we serve. Her unshakable values, distinctive
personality, incredible energy, and nonstop leadership have set an example for
all of us.

GROWTH
   1998 was again a year of growth. In 1995, we committed the company to a plan
to realize such growth. The prior five years had been spent trying to bring our
costs more into line. This was successful, yet it was apparent we had to find
ways to increase the number of customers we served and to increase the size of
our relationship with each customer. Since we had (and are) committed to staying
an independent company, we had to have profitable growth to meet the long term
needs of our shareholders; we naturally focused on ways to do just that. We had
a belief that there was more value in serving present customers well and in
attracting new customers on a one on one basis than in trying to grow by
acquisition.

   During the late 1980's and the early 1990's, we had made a number of bids to
purchase other banks, savings and loans, or bank branch offices. In nearly every
case, we came in second place and sometimes by a large financial amount. Perhaps
the people we were bidding against were smarter or simply better managers. In
any event, we could never figure out how to make the purchase target profitable
enough at the levels being paid. There was an internal rate of return we were
determined to achieve; we couldn't justify the prices many buyers were willing
to pay. If we couldn't see a way to return 15 percent based on our investment,
we refused to bid up. The result of this sound fiscal discipline was that we
acquired very little. We resolved instead to "grow the old-fashioned way: one
customer at a time."

   By opening 15 new banking centers from the end of 1995 through 1998, we
entered new markets and developed new customers. We also opened two new offices
at Trustcorp Mortgage and added four sales officers and markets in our specialty
finance businesses. As a result, our assets have grown from $1.80 billion at the
beginning of the period to over $2.73 billion today. This has been fueled by
annual loan growth averaging 18.7% over these three years. In 1998, our total
loans (including those securitized) grew 15.5 percent and ended the year at
$1.88 billion on the balance sheet and $321 million off the balance sheet. Our
annual mortgage production both in the bank and at Trustcorp Mortgage was $1.42
billion, an 87.9 percent increase

over the prior year and up a full 362 percent over the $306 million dollars
produced in 1995. Today, Trustcorp services a portfolio of some $1.87 billion of
conventional, FHA and VA mortgages. This is up 57.2 percent from the $1.19
billion dollars serviced at the close of 1995. Our business loans also grew
substantially during this period, benefiting from expansion into new markets in
the Michiana area, the purchase of the last of our local business lending
competitors by out of town banks, and the continued growth of our specialty
finance lending. This growth since the end of 1995 was 71.5 percent from $805
million to $1.38 billion. Our consumer loans and leases excluding first
mortgages grew 87.0 percent over the same period and now total $119.3 million.
   Deposit growth has followed the same pattern. After a slow start with some of
our new branches, many began to grow nicely this year. It takes time to enter a
market and develop the trust necessary for people to switch their "business." By
the close of the year our Quantum Leap branches, those we've added as part of
our Vision 2000 growth strategy, accounted for $129.7 million of our deposits.
At year's end, our total deposits stood at $2.18 billion, up 15.1 percent from
the prior year end and up 51 percent since the end of 1995.
   We continue to be focused on expanding our physical presence with new banking
centers offering service and convenience to our customers. As I write this
letter, we are preparing to open a new full service

branch in Warsaw, Indiana and will open at least one more before the end of
1999. We hope to open one Trustcorp Mortgage office in the Midwest region and
plan to add one or two more sales officers in our specialty lending businesses.
If the economy remains solid and we can continue to find good people, we will
pursue a similar set of objectives in 2000.

YEAR 2000 COMPUTER COMPLIANCE
   A topic receiving enormous attention in the press these days is the Year 2000
computer glitch and its predicted impact on banking and other critical
industries. At 1st Source, we have been working diligently to identify, test,
and install date-correcting software to ensure that all our systems are
compliant. We have made significant progress and should have all our mission
critical systems compliant by the end of the second quarter of 1999. We are
confident that we will be ready for the change of the calendar with minimal
disruptions. We have also been developing contingency plans should systems on
which we rely outside of 1st Source become a problem. We know that the end of
the year will present some challenges, but it always does. Computer calculation
problems have occurred before, and we and the industry have been able to handle
them. I am more worried about the expectations and concerns of people leading to
irrational actions in anticipation of problems than I am of the problems
themselves. Unfortunately, there is a whole industry of people who have sprung
up to take advantage of the concerns surrounding Year 2000. Profiteers are
calling for everything from a computer meltdown to the end of the world. . . and
selling their wares to the unprepared. If nothing is going to work next year,
how are all these people expecting to get paid or enjoy their newfound wealth,
generated by preying on the fear of others? I suspect most of them know that
things will be okay and are planning to enjoy their riches! Clearly, there is no
need to panic. We are not talking about insoluble problems. Again, while there
may indeed be concerns with the "millennium" date change, they will most likely
be manageable.

ORGANIZATION
   With Ernie's retirement and my taking on the title of Chairman of the holding
company, it seems only appropriate to recognize two of the people who drive our
businesses. "Duke" Jones (officially Wellington D. Jones III) and Allen Qualey
were promoted to President of their respective businesses, and they will
continue to report to me. Duke is President of 1st Source Bank and is
responsible for the deposit and lending business carried on in our regional
market. The branches, marketing, mortgage, consumer lending, commercial banking,
insurance, wealth management, trust and human resources report to him. He is
responsible for the "sales and service" side of the traditional bank. Duke began
his business career with IBM, joining 1st Source as head of our systems area in
1975. He took over the consumer banking business in 1979 and became Executive
Vice President of both the bank and the holding company in 1989. He and I have
worked in close cooperation for the last 20 years and he is well prepared for
his new duties and has certainly earned his new title. He has an excellent team
of executive managers and senior officers working with him throughout the bank.

   Allen Qualey is responsible for our specialty finance businesses which
include auto and truck financing, turbine and piston aircraft financing and
construction machinery financing. Allen came to 1st Source in 1985 and started
our aircraft finance business. In 1993, he took over the Specialty Finance Group
and has done an excellent job integrating it into the bank. He has added product
lines, new markets and people and has built an efficient and effective
infrastructure to support our national businesses. This title change recognizes
the role he already plays. For the last seven years we have worked closely in
building our customer base and this Group's support operations. Allen will do an
excellent job leading these businesses into the next century.

   Larry Lentych, our Chief Financial Officer, continues to report to me and has
taken on new responsibilities. Administrative Services including buildings and
grounds management, purchasing, communications, and security have joined
finance, accounting and audit as his area of responsibility. This has allowed
Larry Gardner, Senior Vice President and head of Operations and Information
<PAGE>   6

Services, to focus on the Year 2000 issue and the continued upgrade of our
mainframe and PC systems. These are such strategically important areas to our
continued success that it is appropriate that a tighter focus be developed.
Strong management from elsewhere in the bank and some from outside have been
added to ensure the talent necessary to keep 1st Source technologically and
operationally competitive. Jim Kunzler, President of Trustcorp Mortgage, Jim
Jackson, Senior Vice President of our Funds Management Division and Vince
Tamburo, General

Counsel, continue with their previous responsibilities and complete the officer
group reporting directly to me. 
   Inherent in the structure outlined above is a belief in a decentralized 
operating environment with strong senior managers running their businesses.
Having said that, none of us is so good that we don't need our colleagues. One
of the strengths of 1st Source is the collegial nature of its management team.
We have all made mistakes and we all know we are fallible. We seek each others'
advice and we use it. We have a respect for the people here, throughout the
organization. We try to move decision making as close to the customer as
possible. This allows us to grow by developing people so they can manage more
diverse businesses and markets.

PEOPLE
Our future success depends on the ability to attract, train, motivate, and
retain good people. That is getting more difficult. We have always been blessed
with a great group of colleagues who truly like being in service to others. This
is what we do: serve others. We have been blessed, as well, with people who have
a strong set of values. They are attracted to a company that commits itself to
being in the leadership of the communities it serves by using both its financial
and human resources to improve them. Traditionally, our products have been
rather simple and our competition benign. Those days are gone for good.
Competition is rigorous and it comes from a number of areas: at the consumer
level, it is primarily the credit unions who have the advantage of no federal
income tax cost. It is also now the stock brokerages, mutual funds, insurance
companies, credit card companies and a variety of other consumer financial
service providers. For the commercial business it is banks all over the country,
insurance companies, investment banking firms and commercial finance companies.
They have all upgraded their product offerings and sales processes. To compete,
we must as well.
   Our focus has to be on fully developing relationship management with our
customers and doing so with people who are intelligent enough to represent and
discuss a broad array of products and services. We must deliver on our
commitment to keep our customers' best


- --Page 8--


interest in mind; therefore, we need people who are not driven to make every
sale because it results in more income to the individual or the company or both!
Rather, we have to have people who work with their clients on a day to day basis
making sure they are using the right array of products and services to properly
meet their clients' needs. Our colleague's interest must be in building a
relationship of trust where we are proactively working for the client. Our
colleagues need to be much more sales oriented than in the past, they must be
proactive for the benefit of the client! We can no 




 
<PAGE>   7

longer wait until the client hears about a product or service elsewhere and then
asks if we have it, we need to understand needs and fill them. On the other
hand, we must be very careful of not falling into the trap of trying to have
every bell and whistle out there. Often a need is perceived by the client which
is not real and in these cases it is our responsibility to educate the client as
to the value proposition and then fill their real need.

   Over the next year, we will continue to refine our training programs so we
are better able to prepare our colleagues for the competitive markets of the
next century. We must instill the basics and then upgrade our follow-up systems.
We will also have to look for more highly qualified students to fill our entry
level positions. Raw intelligence is important in a knowledge business. However,
it is worthless without the right value system. Our ethical culture at 1st
Source is very strong and we will work hard to see that it is maintained and
enhanced by the next generation of customer service people and sales officers
entering the business.

COMMUNITY INVOLVEMENT
   We can't end this letter without talking about community involvement. It has
always been a core value at 1st Source. As a business we believe we have a
responsibility to make our communities better places to live. We do it by
encouraging our colleagues to become involved in a leadership way. We do it by
continuing a tradition of United Way leadership. We do it by direct financial
support to programs and projects throughout our region that make this a better
place to live. Two examples of this in the past year were the Indiana
University-South Bend Piano Festival which brought international masters and
young talent from all over the country here to collaborate as they prepare
themselves to move to the highest levels of international performance. A week of
incredible study and performance was concluded with a stirring performance by
the Kirov Orchestra from St. Petersburg, Russia. Their tour of the U.S. included
Boston, New York, South Bend, Chicago and San Francisco. 1st Source's leadership
support in money and administration put us among a select few. 1st Source Bank
has also offered long term support to Urban Youth Services. For almost twenty
years, we have provided board member involvement and underwriting of the 1st
Source Bank Academic Awards honoring African-American and Hispanic high-school
students in the program.

   To recognize our own colleagues who give their time in leadership in the
communities we serve and to encourage other businesses to do the same, we have
established the Ernestine M. Raclin Community Leadership Awards which will be
presented for the first time in 1999. Up to five 1st Source employees and five
employees of 1st Source business customers will be recognized. In each case they
will receive the leadership award itself, a $1000 award, and a $1000
contribution to the charity of their choice. A panel of recognized regional
community leaders will make the first selections in February with the awards
presented at a luncheon at the end of March. We believe this is an excellent way
to recognize people's efforts; to bring attention to the importance of
businesses encouraging volunteer commitment; and to honor a woman who taught us
all how to serve.

Thank you for your commitment and support this past year.
     /s/ Christopher J. Murphy
Chairman, President and Chief Executive Officer

Management's Discussion and Analysis of
Financial Condition and Results of Operations

ABOUT OUR BUSINESS
   1st Source Corporation (1st Source) is an Indiana-based, bank holding company
with $2.73 billion in total assets, $2.18 billion in total deposits, $1.88
billion in total loans, and $215.9 million in total shareholders' equity. 1st
Source's principal subsidiary is 1st Source Bank with its main office in South
Bend, Indiana. The assets of the bank account for 96% of the total consolidated

   The bank offers a broad range of commercial banking, personal banking and
trust services. As part of its commercial banking services, 1st Source also
provides highly specialized financing services for automobile fleets in the
rental and leasing industries; privately owned aircraft used by businesses and
individuals; and heavy duty trucks and construction equipment.
   This section of the Annual Report provides a narrative discussion and
analysis of 1st Source's financial condition and results of operations for the
last three years. All tables, graphs, financial statements and notes to the
consolidated financial statements should be considered an integral part of this
analysis.
   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 its markets served; increasing consolidation within
the banking industry; customers and vendors of critical systems or services
failing to comply with Year 2000 programming issues; 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 Corporation and Subsidiaries

RESULTS OF OPERATIONS
   Net income in 1998 was $31.0 million, up from $26.5 million in 1997 and $23.2
million in 1996. Diluted net income per common share was $1.60 in 1998, $1.36 in
1997 and $1.20 in 1996 after giving retroactive recognition to stock splits and
stock dividends.
   Return on average total assets was 1.22% in 1998, compared to 1.21% in 1997
and 1.22% in 1996. Return on average common equity was 15.12% in 1998 versus
14.51% in 1997 and 14.38% in 1996.
   Net income in 1998 was favorably affected by strong noninterest income
growth. By leveraging internal resources, 1st Source has been successful in
generating additional noninterest income as a way to mitigate the competitive
pressures on the interest margin. Offsetting the increase in noninterest income
were expense increases in salaries, leased equipment depreciation and other
expense.
   Dividends declared on common stock in 1998 amounted to $.278 per share,
compared to $.250 in 1997 and $.218 in 1996. The level of earnings reinvested
and dividend payouts are based on management's assessment of future growth
opportunities and the level of capital necessary to support them.
   The quarterly results of operations for the years ended December 31, 1998 and
1997 are summarized below.

BALANCE SHEET COMPOSITION AND MANAGEMENT
   Changes in interest income and interest expense are affected by the
allocation of funds throughout the Statement of Financial Condition. The
following sections discuss the sources from which 1st Source obtains funds and
the manner in which management has chosen to invest these funds.



<PAGE>   12

SOURCE OF FUNDS
   CORE DEPOSITS -- 1st Source's major source of investable funds is provided by
stable core deposits consisting of all interest bearing and non-interest bearing
deposits, excluding brokered certificates of deposit and certain certificates of
deposit of $100,000 and over. In 1998, average core deposits equaled 62.51% of
average total assets, compared to 63.36% in 1997 and 68.32% in 1996. The
effective cost rate of core deposits in 1998 was 3.94%, compared to 3.97% in
1997 and 3.98% in 1996.
   Average demand deposits (non-interest bearing core deposits) increased 19.02%
in 1998, compared to an increase of 12.78% in 1997. They represented 15.73% of
total core deposits in 1998 compared to 15.13% in 1997 and 14.43% in 1996.
   PURCHASED FUNDS -- 1st Source's purchased funds are used to supplement core
deposits and include certain certificates of deposit of $100,000 and over,
brokered certificates of deposit, federal funds, securities sold under
agreements to repurchase, commercial paper and other short-term borrowings.
Purchased funds are raised from customers seeking short-term investments and are
used to balance the bank's interest rate sensitivity. During 1998, 1st Source's
reliance on purchased funds increased to 25.44% of average total assets from
24.29% in 1997.
   LOAN SECURITIZATIONS -- 1st Source sells many of the aircraft and auto loans
it originates through the issuance of securities backed by those loans in
securitization transactions. In a securitization, 1st Source sells and transfers
pools of loans to a wholly-owned, special purpose subsidiary of 1st Source Bank.
The special purpose subsidiary simultaneously sells and transfers its total
interest in the loans to a trust, which issues beneficial interests in the loans
in the form of securities which are sold through private placement transactions.
The special purpose subsidiary generally retains the right to receive any excess
cash flows of the trust. 1st Source sold $346 million of loans in 1998 and $63
million of loans in 1997 in conjunction with aircraft and auto loan
securitization transactions, and revolving agreements related to all current and
previous years' securitizations.
   SHAREHOLDERS' EQUITY -- Management continues to emphasize profitable asset
growth and retention of equity in the business. Average shareholders' equity
equated to 8.05% of average total assets in 1998 compared to 8.30% in 1997.
Shareholders' equity was 7.90% of total assets at year-end 1998, compared to
8.06% at year-end 1997.

INVESTMENT OF FUNDS
   INVESTMENT SECURITIES -- Investment securities at year-end 1998 increased
30.08% from 1997, following a 1.94% decrease from year-end 1996 to year-end
1997. The increase in 1998 is attributed to deposit growth. The decrease in 1997
was attributed to the sale of various securities used to fund a $20 million
bank-owned life insurance program.
   LOANS -- Average loans, net of unearned discount, increased 15.06% in 1998,
following a 19.49% increase in 1997. Loans, net of unearned discount, at
December 31, 1998, were $1.88 billion and were 68.88% of total assets, compared
to $1.80 billion or 74.30% of total assets at December 31, 1997.
   Commercial and agricultural lending outstandings, excluding those secured by
real estate, increased 9.50% during 1998. 1st Source has experienced success in
its market as customers seek professional personal service with local
decision-making authority.
   Commercial loans secured by transportation and construction equipment at
year-end 1998 decreased 2.68% from year-end 1997. The decrease is reflective of
the $346 million of aircraft and auto loans sold through securitizations in
1998. Despite this, there were strong originations in construction equipment,
auto rental franchises, aircraft and truck, and automobile leasing company
financings.
   Real estate loans recorded growth of 11.05% during 1998.  This increase was 
led by residential mortgage loans held for sale with an increase of 44.83%,

followed by an increase of 9.89% in commercial real estate lending. Portfolio
residential mortgage loans decreased 13.34% from 1997.
   Consumer loans grew a modest 6.90% in 1998.
   LIQUIDITY RISK MANAGEMENT -- The Asset/Liability management process
incorporates overall bank liquidity and interest rate sensitivity. The purpose
of liquidity management is to match the sources and use of funds to anticipated
customer deposits, withdrawals and borrowing requirements, as well as to provide
for the cash flow needs of 1st Source. The primary source of liquidity is the
investment portfolio. At December 31, 1998, securities maturing in one year
amounted to $147.6 million which represented 27.34% of the investment portfolio
as compared to 23.59% at year-end 1997. Other alternative sources of funds are
loan repayments and loan securitizations. The liquidity of 1st Source is further
enhanced by a significant concentration of core deposits and $100,000-and-over
certificates of deposit. Both provide a relatively stable funding base.
   INTEREST RATE RISK MANAGEMENT -- The Asset/Liability Management Committee of
1st Source monitors and manages the relationship of earning assets to interest
bearing liabilities and the responsiveness of asset yields, interest expense and
interest margins to changes in market interest rates. In the normal course of
business, 1st Source faces ongoing interest rate risks and uncertainties. 1st
Source occasionally utilizes interest rate swaps to partially manage the primary
market exposures associated with the interest rate risk related to underlying
assets, liabilities, and anticipated transactions. Under the current interest
rate swaps, 1st Source entered into agreements with another party to exchange,
at specific intervals, the difference between fixed-rate and floating-rate
interest amounts as calculated by reference to a notional amount as a means to
convert floating rate loans to a fixed rate. The notional amounts total $26.9
million at December 31, 1998. The current positions are not leveraged and are
not held for trading.
   A hypothetical change in earnings was modeled by calculating an immediate 100
basis point (1.00%) change in interest rates across all maturities. This
analysis presents the hypothetical change in earnings of those rate sensitive
financial instruments and interest rate swaps held by 1st Source (excluding
Trustcorp Mortgage) at December 31, 1998. The aggregate hypothetical loss in
pre-tax earnings is estimated to be $2,440,690 on an annualized basis on all
rate sensitive financial instruments and the interest rate swaps based on a
hypothetical increase of a 100 basis point change in interest rates. The
aggregate hypothetical increase in pre-tax earnings is estimated to be
$2,386,140 on an annualized basis on all rate sensitive financial instruments
and the interest rate swaps based on a hypothetical decrease of a 100 basis
point change in interest rates. Actual results may differ materially from those
projected. The use of this methodology to quantify the market risk of the
balance sheet should not be construed as an endorsement of its accuracy or the
accuracy of the related assumptions.

INVESTMENT OF FUNDS -- CONCLUDED

   Due to the nature of the mortgage banking business, 1st Source manages the
earning assets and interest-bearing liabilities of Trustcorp Mortgage Company on
a separate basis. The predominant assets on Trustcorp's balance sheet are
mortgage loans held for sale, which are funded by short-term borrowings
(normally less than 30 days) from non-affiliated banks. These borrowings are
managed on a daily basis. Trustcorp's other borrowings for working capital and
purchases of servicing assets are funded by 1st Source Corporation and
non-affiliated

<PAGE>   14

banks. 
Trustcorp manages the interest rate risk related to loan commitments by entering
into contracts for future delivery of loans. (See Note M of Notes to
Consolidated Financial Statements.)

</TABLE>

EARNING RESULTS
   Net interest income, the difference between income from earning assets and
the interest cost of funding those assets, is 1st Source's primary source of
earnings. Net interest income, on a fully taxable equivalent basis, increased
8.74% in 1998, following a 13.31% increase in 1997.
   Net interest margin, the ratio of net interest income to average earning
assets, is affected by movements in interest rates and changes in the mix of
earning assets and the liabilities that fund those assets. Net interest margin
on a fully taxable equivalent basis was 4.16% in 1998 compared to 4.38% in 1997
and 4.48% in 1996. The interest margin has decreased the last two years due to
competitive pricing pressures. In addition, 1st Source has relied more on
purchased funds to meet loan demand.
   The yield on earning assets in 1998 was 8.52%, compared to 8.65% in 1997 and
8.64% in 1996. Average earning assets in 1998 increased 14.56%, following a
15.82% increase in 1997. The effective rate on interest bearing liabilities was
5.10% in 1998, compared to 5.04% for 1997 and 4.85% for 1996.
   NONINTEREST INCOME -- Supplementing the growth in net interest income was an
increase in noninterest income of 44.49% over 1997. The factors influencing the
growth were increased aircraft

and auto loan securitization and servicing income, revenues generated from
operating leases, and the origination and sale of mortgage loans and servicing.
Noninterest income in 1997 increased 39.94% over 1996


<PAGE>   15


primarily for the same reasons as in the current year.
   Trust fees in 1998 were $8.26 million, compared to $7.31 million in 1997 and
$6.73 million in 1996. Trust fees increased 12.92% in 1998, following an 8.62%
increase in 1997.
   Service charges on deposit accounts increased by 8.64% resulting in $5.84
million of income for 1998. The $5.38 million recorded in 1997 was an increase
of 11.41% from the $4.83 million of service charges on deposit accounts
generated in 1996.
   Loan servicing and sale income generated from 1st Source's aircraft and auto
loan securitization and mortgage banking activities increased 56.88% to $15.12
million in 1998. The $9.64 million recorded in 1997 represented a 78.28%
increase over 1996.
   1st Source recognized loan securitization gains of $1.95 million during 1998,
compared to $800,000 during 1997. Aircraft and auto loan servicing income in
1998 was $6.62 million, compared to $3.76 million in 1997. Servicing income has
increased as the result of additional loan sales. The outstanding servicing
portfolio grew to $321 million at year-end 1998, compared to $111 million at the
end of 1997.
   Gains of $4.86 million were recognized on the origination and sale of
mortgage loans and servicing in 1998, compared to gains of $3.38 million in
1997. In addition, net servicing fees on mortgages remained steady at $1.69
million for both 1998 and 1997. As of year-end 1998, Trustcorp Mortgage
Company's mortgage servicing portfolio aggregates $1.87 billion, as compared to
$1.30 billion one year ago.
   Equipment rental income generated from operating leases increased to $12.56
million in 1998, nearly an 81% increase over 1997. The $6.95 million recorded in
1997 was nearly a 154% increase over 1996. Revenues from operating leases for
construction equipment, automobiles and other equipment, and the related
depreciation on the equipment, have increased significantly in the past three
years as 1st Source has focused on increasing this line of business.
   Other income increased 51.42% during 1998, following an increase of 23.44% in
1997. This growth in 1998 was generated primarily by an increase in mortgage
loan fees as homeowners took advantage of lower interest rates to refinance
their mortgages. In addition, increases were realized in insurance commissions,
standby letter of credit fees and appreciation in cash surrender value of
bank-owned life insurance (BOLI). The growth in 1997 was fueled by increases in
cash surrender value of BOLI, mortgage underwriting fees and standby letter of
credit fees.
   The 1998 and 1997 net losses recorded for investment securities and other
represent, primarily, the write-offs of venture capital investments.
   NONINTEREST EXPENSE -- During 1998, 1st Source experienced an increase in
noninterest expense of 17.16% primarily attributed to costs to attract and
retain quality people. In addition, the depreciation on our growing operating
lease portfolio and professional consulting expenses contributed to the overall
increase in operating expenses. Cost control across all business units and
better utilization of resources continues to be a major focus at 1st Source. The
increase in noninterest expense during 1997 of 20.38% was primarily due to the
branch expansion, salaries, operating lease depreciation and additional
provisions needed for our stock incentive reserves.
   Salaries and employee benefits comprised approximately 55% of total
noninterest expense in 1998 compared to 57% in 1997. Salaries and employee
benefits increased 13.20% in 1998, following a 15.80% increase in 1997. Salaries
and wages increased 15.61% in 1998 and 12.73% in 1997. The number of full-time
equivalent employees stood at 1,036 at the end of 1998, compared to 966 and 895
at the end of 1997 and 1996, respectively. Employee benefits increased 5.34% in
1998, following a 27.07% increase in 1997. The smaller increase in employee
benefits was primarily the result of additional provisions made during 1997 to
fund the stock incentive reserves due to the significant 63% increase in the
market price of 1st Source common stock during that period. Group insurance
expense increased 20.01% in 1998, following a 9.86% decrease in 1997.
   Occupancy expense in 1998 increased 9.26% from 1997, following a 3.22%
decrease in 1997. The increase in occupancy expense in 1998 is primarily due to
the full year impact of the previous year's branch expansion. The reduction in
occupancy expense in 1997 is attributed to greater tenant occupancy of our
head-quarters building. Furniture and equipment expense increased in 1998

EARNING RESULTS -- CONTINUED
by 7.15%, following a 15.07% increase in 1997. The increase in 1997 is
attributed to depreciation on new furniture and equipment. 
   Depreciation on operating leases increased 80% in 1998, following a 176%
increase in 1997 due to the increased volume of operating leases. 
   Business development and marketing expense increased 2.98% in 1998, following
an increase of 33.78% in 1997. Contributions to the 1st Source Foundation
declined in 1998 compared to 1997.
   An increase of 17.72% occurred in other expenses during 1998, compared to a
19.56% increase in 1997. During 1998, the majority of the increase in other
expenses was in professional consulting. The increase in professional consulting
expenses was attributed to loan securitization activity and costs in upgrading
various computer systems for Year 2000 (Y2K) compliance. During 1997, 1st Source
experienced increases in employee acquisition and training, communications,
professional consulting and collection and repossession expenses.
   YEAR 2000 -- The Y2K issue is the result of potential problems with computer
systems or any equipment with computer chips that store the year portion of the
date as just two digits (e.g., 98 for 1998). Systems using this two-digit
approach may not be able to determine whether "00" represents the Year 2000 or
1900. The problem, if not corrected, may make those systems fail altogether or,
even worse, allow them to generate incorrect calculations causing a disruption
of normal operations.
   In 1997, a comprehensive project plan to address the Y2K issue as it relates
to 1st Source's operations was developed, approved by the Board of Directors and
implemented. The scope of the plan has five phases comprising Awareness,
Assessment, Renovation, Validation and Implementation as defined by federal
banking regulatory agencies. Two project teams were assigned. The first
consisted of key members of the technology staff, representatives of functional
business units and senior management. The second primarily consisted of lenders
and credit personnel. The first team assessed our systems and equipment and
vendors to ascertain their readiness and to develop the overall plan to bring
our systems into compliance. The second team assessed the readiness of our
customers and determined what risk, if any, our key customers pose to the bank
with regards to their Y2K readiness. Additionally, the duties of the Senior Vice
President of Operations were realigned to allow him to serve as the Year 2000
Project Manager.
   The scope of the project also includes other operational and environmental
systems since they may be impacted if embedded computer chips control the
functionality of those systems. From the assessment, 1st

<PAGE>   18

Source has identified and prioritized those systems deemed to be mission 
critical or those that have a significant impact on normal operations.
   1st Source relies on third-party vendors and service providers for much of
its data processing capabilities and to maintain its computer systems. Formal
communications with these providers and other external counterparties were
initiated in 1997 to assess the Y2K readiness of their products and services.
Their progress in meeting their targeted schedules is being monitored
continually for any indication that they may not be able to address the problems
in time. Thus far, responses indicate that all of the significant providers
currently have compliant versions available or are well into the renovation and
testing phases. However, 1st Source can give no guarantee that the systems of
these service providers and vendors on which 1st Source's systems rely will be
timely renovated.
   Additionally, 1st Source has implemented a plan to manage the potential risk
posed by the impact of the Y2K issue on its major borrowing customers. Formal
communications have been initiated, and the assessment was substantially
complete on December 31, 1998. Loan losses attributed to the Y2K issue are not
anticipated to be material to 1st Source. However, there can be no guarantee
that any loss incurred will be immaterial.
   1st Source's total cost for the Y2K project is estimated to be between
$900,000 and $1,700,000. The total amount expended on the project through
December 31, 1998, was $630,000 of which approximately $610,000 related to the
cost to repair or replace software. Approximately $9,000 was related to the cost
of replacing equipment and approximately $11,000 was related to miscellaneous
items such as training for employees and communications with customers.


- --Page 21--

   Funds have been provided from our normal operating budget and costs are
expensed as they are incurred.
   The total cost to 1st Source of these Year 2000 readiness activities has not
been, and is not anticipated to be, material to its financial position or
results of operations in any given year.
   The project teams feels that 1st Source's Y2K readiness project is on
schedule. The following table provides a summary of the current status of the
five phases involved and a projected timetable for completion.

Implementation                     70%                       June 30, 1999

   No specific other projects have been deferred due to this project. Much of
the work done within this project is an acceleration of work that would have
been done in the normal course of business.
   The costs and timetable in which 1st Source plans to complete the Year 2000
readiness activities are based on management's best estimates, which were
derived using numerous assumptions of future events including the continued
availability of certain resources, third-party plans and other factors. 1st
Source can make no guarantee that these estimates will be achieved and actual
results could differ from such plans.
   Based upon current information related to the progress of its major vendors
and service providers, management has determined that the Y2K issue will not
pose significant operational problems for its computer systems. This
determination is based on the ability of those vendors and service providers to
renovate, in a timely manner, the products and services on which 1st Source's
systems rely. However, 1st Source can give no guarantee that the systems of
these suppliers will be renovated in a timely manner.
   Realizing that some disruption may occur despite its best efforts, 1st Source
is in the process of developing contingency plans for each critical system in
the event that one or more of those systems fail. While this is an ongoing
process, 1st Source expects to have the plans substantially documented by June
30, 1999.
   INCOME TAXES -- Federal income taxes were $13.26 million and $10.79 million,
prior to the tax benefit of $1,196,000 and $936,000 relating to the distribution
on preferred securities of subsidiary trusts for 1998 and

<PAGE>   19

1997, respectively. After this benefit, 1998 federal income taxes were $12.06
million, or 28.01% of income after state taxes, compared to $9.86 million or
27.12% in 1997 and $9.13 million or 28.24% in 1996. The higher percentage of
federal income taxes in 1998 is the result of less tax-exempt income. A
settlement with the Internal Revenue Service was reached during 1997 over a
dispute arising from the 1983 purchase of the First National Bank of Mishawaka
relating to deduction of core deposit intangibles. Interest of $955,000 related
to the settlement was paid to the IRS in 1998. State income taxes were $4.28
million and $3.60 million in 1998 and 1997, respectively, prior to the tax
benefit of $318,000 and $248,000 relating to the distribution on preferred
securities of subsidiary trusts for 1998 and 1997, respectively. After this
benefit, 1998 state income taxes were $3.96 million, compared to $3.35 million
in 1997 and $3.27 million in 1996.

CREDIT EXPERIENCE
   PROVISION FOR LOAN LOSSES -- The ability of a bank to identify and assess the
risk factors affecting its loan portfolio is crucial for profitability.
Management follows a credit policy that balances the risk and return on loans
and monitors potential credit problems to ensure that they are adequately
managed and reserved.
   The provision made to the reserve for loan losses is determined by management
based on the risk factors and general economic conditions affecting the loan
portfolio, including changes to the portfolio mix and past loan loss experience.
The provision for loan losses for 1998 was $9.16 million, compared to $6.05
million in 1997 and $4.65 million in 1996. Net charge-offs of $3.65 million,
$144,000, and $1.78 million were recorded in 1998,


- --Page 22--

1997 and 1996, respectively.
   The reserve for loan losses at December 31, 1998 totaled $40.93 million and
was 2.18% of loans, compared to $35.42 million or 1.97% of loans at December 31,
1997, and $29.52 million or 2.03% of loans at December 31, 1996. It is
management's opinion that the reserve for loan losses is adequate to absorb
anticipated losses in the loan portfolio as of December 31, 1998.
   NONPERFORMING ASSETS -- 1st Source's policy is to discontinue the accrual of
interest on loans on which principal or interest is past due and remains unpaid
for 90 days or more, unless the loan is well collateralized and in the process
of collection. Nonperforming assets amounted to $10.57 million at December 31,
1998, compared to $11.44 million at December 31, 1997 and $7.77 million at
December 31, 1996. Impaired loans totaled $13.30 million, $9.39 million and
$8.13 million at December 31, 1998, 1997 and 1996, respectively.

   EFFECTS OF INFLATION -- The results of operations can also be affected by
inflation, although it is difficult to measure the precise impact on the various
types of income and expense. Interest rates, in particular, are significantly
affected by inflation, but neither the timing nor the magnitude of the changes
coincide with changes in the consumer price index nor other measures of
inflation. Additionally, increases in interest rates, such as those on consumer
deposits, lag behind increases in overall rates. This, in turn, affects the
composition of sources of funds by reducing core deposit growth and increasing
the need for purchased funds. Another significant effect of inflation is on
noninterest expenses, which tend to rise during periods of general inflation.

Notes to Consolidated Financial Statements
1st Source Corporation and Subsidiaries


NOTE A -- ACCOUNTING POLICIES
   The principal line of business of 1st Source Corporation ("1st Source") and
subsidiaries is banking and closely related activities. The following is a
summary of significant accounting policies followed in the preparation of the
consolidated financial statements.
   PRINCIPLES OF CONSOLIDATION -- The financial statements consolidate 1st
Source and its subsidiaries (principally 1st Source Bank and Trustcorp Mortgage
Company). All significant intercompany balances and transactions have been
eliminated. For purposes of the parent company only financial information
presented in Note Q, investments in subsidiaries are carried at 1st Source's
equity in the underlying net assets.
   USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS -- The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements, and
the reported amounts of income and expenses during the reporting period. Actual
results could differ from those estimates.
   INVESTMENT SECURITIES -- Securities that may be sold as part of 1st Source's
asset/liability or liquidity management or in response to or in anticipation of
changes in interest rates and resulting prepayment risk, or for other similar
factors, are classified as available-for-sale and carried at fair market value.
Unrealized holding gains and losses on securities available-for-sale are
reported net of related deferred income taxes as a separate component of
shareholders' equity and the change in such items is a component of
comprehensive income. Securities that 1st Source has the ability and positive
intent to hold to maturity are classified as held-to-maturity and carried at
amortized cost. Trading securities are carried at fair market value with
unrealized holding gains and losses included in earnings. There were no trading
securities at December 31, 1998 or 1997. Realized gains and losses on the sales
of all securities are reported in earnings and computed using the specific
identification cost basis.
   LOANS -- 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. Included in real estate loans
are loans held for sale totaling $188.2 million and $130.0 million at December
31, 1998 and 1997, respectively.


<PAGE>   27


   SECURITIZED ASSETS -- The guidelines set forth in Statement of Financial
Accounting Standards (SFAS) No. 125, "Accounting for Transfers and Servicing of
Financial Assets and Extinguishment of Liabilities," are followed when
accounting for securitizations. When 1st Source sells loans in securitizations,
it retains servicing rights and interest-only strips, which are retained
interests in the securitized assets. Gain or loss on sale of the loans depends
in part on the previous carrying amount of all retained interests, allocated in
proportion to their fair value. 1st Source generally estimates fair value based
on the present value of future cash flows expected under management's best
estimates of the key assumptions - credit losses, prepayment speeds, forward
yield curves and discount rates commensurate with the risks involved and
regularly reviews all assets for impairment. In conjunction with its
securitization activities, 1st Source sold $346 million of aircraft and auto
loans in 1998 resulting in a recognized gain of $1.95 million.
   Approximately $83,000 of cash and $9.1 million of other assets shown on the
December 31, 1998 consolidated statement of financial condition are assets of
1st Source Funding Corporation ("Funding"), a special-purpose subsidiary of 1st
Source Bank, and represent Funding's beneficial (i.e. residual) interest in
certain assets of the 1st Source Master Trust in accordance with 1st Source's
loan securitization transactions. Funding was established in 1998 as a
qualifying special-purpose entity for purposes of SFAS No. 125 and has been
structured to be bankruptcy-remote from 1st Source and its other affiliates.
   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. Gains and losses on the sale
of mortgage servicing rights are recognized as non-interest income in the period
in which such rights are sold on a servicing released basis.
   SFAS No. 125 also requires companies that intend to 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. As of December 31, 1998, and 1997, $20.3 million
and $11.0 million, respectively, of mortgage servicing rights have been
capitalized. As of these dates, the servicing rights had a fair value of $35.7
million and $21.0 million respectively.
   Mortgage servicing rights are being amortized using a method which
approximates the effective yield method and for the years ended December 31,
1998, 1997 and 1996,


- --Page 30--

NOTE A -- ACCOUNTING POLICIES -- CONTINUED 
   $4.09 million, $2.72 million and $2.68  million of amortization expense has
been recognized.
   SFAS No. 125 also requires 1st Source to assess its capitalized servicing
rights for impairment based on their current fair value. 1st Source
disaggregates its servicing portfolio based on loan type and interest rate, the
predominant risk characteristics of the underlying loans. There were no
valuation allowances associated with capitalized mortgage servicing rights at
December 31, 1998 and 1997.
   REVENUE RECOGNITION -- Interest on loans is included in interest income on
the accrual method over the terms of the loans based upon principal balances
outstanding. The accrual of interest on loans is discontinued when a loan
becomes contractually delinquent for 90 days, except for installment loans where
payments are being received regularly and mortgage loans, which are placed on
nonaccrual at the time the loan is placed in foreclosure. When interest accruals
are discontinued, interest credited to income in the current year is reversed,
and interest accrued in the prior year is charged to the reserve for loan
losses. Management may elect to continue the accrual of interest when the net
realizable value of collateral is sufficient to cover the principal and accrued
interest. Certain loan origination and commitment fees and certain direct loan
origination costs are deferred and the net amount amortized to interest income
generally over the contractual life of the related loan or commitment. 

RESERVE FOR LOAN LOSSES -- A loan is considered impaired, based on current
information and events, if it is probable that 1st Source will be unable to
collect the scheduled payments of principal or interest when due according to
the contractual terms of the loan agreement. The measurement of impaired loans
is generally based on the present value of expected future cash flows discounted
at the historical effective interest rate, except that all collateral-dependent
loans are measured for impairment based on the fair value of the collateral. The
provision for loan losses charged to expense is based upon the actual net loan
losses incurred as determined by credit loss experience, the evaluation of
potential losses in the portfolio and the evaluation of impaired loans. Loans
are charged against the reserve for loan losses when deemed uncollectible.

<PAGE>   28


   PREMISES AND EQUIPMENT -- Premises and equipment are stated at cost, less
accumulated depreciation. The provision for depreciation is computed generally
by the straight-line method, primarily with useful lives of 5, 7, 15 and 31H
years.
   LEASED ASSETS -- 1st Source finances various types of equipment and
automobiles under leases principally classified as operating leases. These
assets are being depreciated on a straight-line method over the life of the
lease.
   TRUST FEES -- Trust fees are recognized on the accrual basis.
   INCOME TAXES -- Deferred income taxes are determined under the liability
method. The net deferred tax assets are comprised of the tax effect of net
temporary differences related principally to differing methods of accounting for
loan losses offset by differing methods of accounting for depreciation on
premises and leased equipment and amortization of purchased mortgage servicing
rights.
   NET INCOME PER COMMON SHARE -- Net income per common share is computed in
accordance with SFAS No. 128, "Earnings per Share." Basic earnings per share is
computed by dividing net income by the weighted average number of shares of
common stock outstanding which were as follows (in thousands): 1998, 18,995;
1997, 18,935; and 1996, 18,893. Diluted earnings per share is computed by
dividing net income by the weighted average number of shares of common stock
outstanding plus the dilutive effect of outstanding stock options. The weighted
average number of common shares, increased for the dilutive effect of stock
options, used in the computation of diluted earnings per share were as follows
(in thousands): 1998, 19,371; 1997, 19,543; and 1996, 19,357.
   The computations of the weighted average number of common shares used for the
determination of both basic and diluted earnings per share give retroactive
recognition to a 10% stock dividend declared January 14, 1999, payable February
12, 1999, to shareholders of record on February 4, 1999.
   FUNDS HELD IN TRUST FOR INVESTORS AND MORTGAGORS -- As of December 31, 1998
and 1997, serviced loans which were owned by investors aggregated $1.87 billion
and $1.30 billion, respectively. Funds held in trust at 1st Source for the
payment of principal, interest, taxes and insurance premiums applicable to
mortgage loans being serviced for others, aggregated approximately $50.8 million
and $23.0 million at December 31, 1998 and December 31, 1997, respectively.
   CASH FLOW INFORMATION -- For purposes of the consolidated and parent company
only statements of cash flows, 1st Source considers cash and due from banks as
cash and cash equivalents. Cash paid during the years ended December 31, 1998,
1997 and 1996, for interest and for income taxes was $100.2 million and $7.8
million, $83.7

NOTE A -- ACCOUNTING POLICIES -- CONCLUDED
million and $10.7 million, and $73.3 million and $14.9 million, respectively.
   OFF-BALANCE SHEET FINANCIAL INVESTMENTS -- 1st Source enters into interest
rate swap agreements as part of its interest rate risk management strategies.
These instruments are accounted for under the accrual basis of accounting,
whereby the income or expense is recorded as a component of interest income. If
a swap is terminated, the resulting gain or loss is deferred and amortized over
the remaining life of the off-balance sheet investment product.
   RECENT ACCOUNTING PRONOUNCEMENTS -- 1st Source has adopted SFAS No. 130,
"Reporting Comprehensive Income," as of January 1, 1998. SFAS No. 130
establishes standards for the reporting and disclosure of comprehensive income
and its components in a full set of general purpose financial statements. The
only component of comprehensive income not included in 1st Source's net income
is unrealized gains or losses on available-for-sale investment securities, net
of related income taxes. Prior year financial statements have been restated in
order to conform to the requirements of SFAS No. 130.
   In June 1997, the Financial Accounting Standards Board (FASB) issued SFAS No.
131,"Disclosure about Segments of an Enterprise and Related Information." This
Statement changes the manner in which public companies report segment
information in annual reports and requires companies to report selected segment
information in interim financial reports. Companies are now required to report
financial and descriptive information about the company's operating segments.
1st Source's principal business is banking, and management has not separately
organized the business beyond commercial banking and mortgage banking. Its
wholly owned mortgage subsidiary, Trustcorp Mortgage Company, constitutes a
segment by definition of SFAS No. 131, however, it does not meet the
quantitative thresholds for separate disclosure as set forth by this Statement.
Trustcorp Mortgage Company's revenue is less than 10 percent of consolidated
revenue, the absolute amount of its reported income is less than 10 percent of
the absolute amount of the consolidated net income of 1st Source, and, finally,
its assets are less than 10 percent of consolidated assets.


                                      158
<PAGE>   29


   In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." SFAS No. 133 is effective for all fiscal
quarters of all fiscal years beginning after June 15, 1999 (January 1, 2000 for
1st Source). SFAS No. 133 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. 1st Source anticipates that due to its limited use of derivative
instruments, the adoption of SFAS No. 133 will not have a significant effect on
1st Source's results of operations or its financial position.
   RECLASSIFICATIONS -- Certain amounts in the 1996 and 1997 consolidated
financial statements have been reclassified to conform with the 1998
presentation. These reclassifications had no effect on total assets,
shareholders' equity or net income as previously reported.


NOTE B -- FAIR VALUES OF FINANCIAL INSTRUMENTS
   The fair values of 1st Source's financial instruments as of December 31, 1998
and 1997, are summarized in the following table.
   The following methods and assumptions were used by 1st Source in estimating
the fair value of its financial instruments:
   CASH AND CASH EQUIVALENTS -- The carrying values reported in the consolidated
statements of financial condition for cash and due from banks, federal funds
sold and interest bearing deposits with other banks approximate their fair
values.
   INVESTMENT SECURITIES -- Fair values for investment securities are based on
quoted market prices, where available. If quoted market prices are not
available, fair values are estimated based on quoted market prices of comparable
investments.
   LOANS -- For variable rate loans that reprice frequently and with no
significant change in credit risk, fair values are based on carrying values. The
fair values for certain real estate loans (e.g., one-to-four single family
residential mortgage loans) are based on quoted market prices of similar loans
sold in conjunction with securitization transactions, adjusted for differences
in loan characteristics. The fair values of all other loans are estimated using
discounted cash flow analyses, using interest rates currently being offered for
loans with similar terms to borrowers of similar credit quality.


- --Page 32--

NOTE B -- FAIR VALUES OF FINANCIAL INSTRUMENTS -- CONCLUDED
   DEPOSITS -- The fair values for all deposits other than time deposits are
equal to the amounts payable on demand (the carrying value). Fair values of
variable rate time deposits are equal to their carrying values. Fair values for
fixed rate time deposits are estimated using discounted cash flow analyses using
interest rates currently being offered for deposits with similar remaining
maturities.
   SHORT-TERM BORROWINGS -- The carrying values of federal funds purchased,
securities sold under repurchase agreements and other short-term borrowings
approximate their fair values.
   LONG-TERM DEBT -- The fair values of 1st Source's long-term debt are
estimated using discounted cash flow analyses, based on 1st Source's current
estimated incremental borrowing rates for similar types of borrowing
arrangements.
   GUARANTEED PREFERRED BENEFICIAL INTERESTS IN THE COMPANY'S SUBORDINATED
DEBENTURES (CUMULATIVE TRUST PREFERRED SECURITIES) -- Fair values are based on
quoted market prices.
   GUARANTEES AND LOAN COMMITMENTS -- Contract and fair values for certain of
1st Source's off-balance-sheet financial instruments (guarantees and loan
commitments) are estimated based on fees currently charged to enter into similar
agreements, taking into account the remaining terms of the agreements and the
counterparties' credit standing.
   INTEREST RATE SWAPS -- Fair values for interest rate swaps are based on the
net amount necessary to currently settle the transaction.
   LIMITATIONS -- Fair value estimates are made at a discrete point in time
based on relevant market information and information about the financial
instruments. Because no market exists for a significant portion of 1st Source's
financial instruments, fair value estimates are based on judgments regarding
future expected loss experience, current economic conditions, risk
characteristics of various financial instruments and other such factors.
   These estimates are subjective in nature and involve uncertainties and
matters of significant judgment and therefore cannot be determined with
precision. Changes in assumptions could significantly affect the estimates. In
addition, the fair value estimates are based on existing on and
off-balance-sheet financial instruments without attempting to estimate the value
of anticipated future business and the value of assets and liabilities that are
not considered financial instruments. For example, 1st Source has a substantial
annual trust net fee income. The trust business is not considered a financial
instrument and its value has not been incorporated into the fair value
estimates.
   Other significant assets and liabilities that are not considered financial
instruments include the mortgage banking operation,


                                      159
<PAGE>   30


premises and equipment and other assets. In addition, for investment and
mortgage-backed securities, the income tax ramifications related to the
realization of unrealized gains and losses can have a significant effect on fair
value estimates and have not been considered in many of the estimates. Also, the
fair value estimates for deposits do not include the benefit that results from
the low-cost funding provided by the deposit liabilities compared to the cost of
borrowing funds in the market.

NOTE C -- RESTRICTIONS ON CASH DUE FROM BANKS
   1st Source Bank is required to maintain reserve balances with the Federal
Reserve Bank. The average amount of those reserve balances for the year ended
December 31, 1998 was approximately $13.0 million.
   Under available line of credit agreements, 1st Source may borrow up to $3
million. At December 31, 1998, there were no outstanding borrowings under these
lines, which were assigned to support commercial paper borrowings.

NOTE D -- INVESTMENT SECURITIES
   The amortized cost and estimated aggregate fair value of securities
classified as available-for-sale and held-to-maturity at December 31, 1998, are

   At December 31, 1998 and 1997, loans amounting to $9.27 million and $10.03
million, respectively, substantially all of which are collateralized, are
considered to be nonaccrual or restructured loans. Interest income for the years
ended December 31, 1998, 1997 and 1996 would have increased by approximately
$719,000, $786,000, and $533,000, respectively, if these loans earned interest
at their full contract rate.
   As of December 31, 1998 and 1997, impaired loans totaled $13.30 million and
$9.39 million, respectively, of which $3.73 million and $1.14 million had
corresponding specific reserves for loan losses totaling $1.18 million and $0.61
million, respectively. The remaining balances of impaired loans had no specific
reserves for loan losses associated with them. The vast majority of the impaired
loans are nonaccrual loans; interest is not recognized on nonaccrual loans
subsequent to the date the loan is placed in nonaccrual status. While a loan is
classified as nonaccrual and the future collectibility of the recorded loan
balance is doubtful, collections on interest and principal are generally applied
as a reduction to principal outstanding. Interest on the remainder of the
impaired loans is recognized on the accrual basis. For 1998 and 1997, the
average recorded investment in impaired loans was $13.28 million and $9.46
million, respectively, and interest income recognized on impaired loans totaled
$1.23 million and $508,000, respectively.

NOTE H -- COMMON STOCK
   Effective January 1, 1996, 1st Source adopted SFAS No. 123, "Accounting for
Stock-Based Com-pensation," on a disclosure basis only. The disclosure
requirements include reporting the pro forma effect on net income and net income
per share of compensation expense that is attributable to the fair value of
stock options and other stock-based compensation that have been issued to
employees under the Stock Option Plans and the Employee Stock Purchase Plan. 1st
Source will continue to apply APB No. 25 in accounting for these plans. The
Executive Incentive Plan, the Special Long-Term Incentive Award Plan and the
Restricted Stock Award Plan are already being accounted for as compensatory
plans in accordance with the provisions of SFAS No. 123. Compensation cost that
has been charged against income for these plans was $3.05 million, $1.83
million, and $1.52 million for the years ended December 31, 1998, 1997 and 1996,
respectively.

STOCK OPTION PLANS
   1st Source's incentive stock option plans include the 1992 Stock Option Plan
(the "1992 Plan") and a certain other stock option agreement which became
effective January 1, 1992. As of December 31, 1998, an aggregate of 2,090,619
shares of common stock are reserved for issuance under the above plans. Under
the 1992 Plan, the exercise price of each option equals the market price of 1st
Source stock on the date of grant and an option's term is 10 years. Options
under the 1992 Plan generally vest in one to five years from date of grant.
Options are granted on a discretionary basis by the Executive Compensation
Committee (the "Committee") of the 1st Source Board of Directors.
   The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option pricing model with the following weighted-average
assumptions used for grants in 1998: dividend yield of .74%; expected volatility
of 19.60%; risk-free interest rate of 5.50%; and expected life of 6.47 years.
   The following is a summary of the activity with respect to 1st Source's stock
option plans for the years ended December 31, 1996, 1997 and 1998:

NOTE H -- COMMON STOCK -- CONCLUDED

EMPLOYEE STOCK PURCHASE PLAN
   1st Source also has an employee stock purchase plan for substantially all
employees with at least two years of service on the effective date of an
offering under the plan. Eligible employees may elect to purchase any dollar
amount of stock so long as such


                                      165

<PAGE>   36

amount does not exceed 25% of their base rate of pay and the aggregate stock
accrual rate for all offerings does not exceed $25,000 in any calendar year.
Payment for the stock is made through payroll deductions over the offering
period, and employees may discontinue the deductions at any time and exercise
the option or take the funds out of the program. The most recent offering began
June 1, 1998, and runs through May 31, 2000, with $386,216 in stock value to be
purchased at $32.05 per share. The fair value of the employees' purchase rights
for the 1998 offering was estimated using the Black-Scholes model with the
following assumptions: dividend yield of .74%; expected volatility of 17.53%;
risk-free interest rate of 5.52%; and expected life of two years.
   Pro forma net income and diluted net income per common share, reported as if

EXECUTIVE INCENTIVE PLAN
   1st Source has an Executive Incentive Plan which is administered by the
Committee. Awards under the plan include "Book Value" shares of common stock.
These shares are awarded annually based on weighted performance criteria and
vest over a period of five years. The plan shares may only be sold to 1st
Source, and such sale is mandatory in the event of death, retirement, disability
or termination of employment. Grants under the plan for 1998, 1997 and 1996 are
summarized below:

SPECIAL LONG-TERM INCENTIVE AWARD
   During February 1996 and March 1991, 1st Source granted special long-term
incentive awards, including 1st Source common stock, to participants in the
Executive Incentive Plan. Shares granted under the plan vest over a period of
ten years. The first 10% was vested at the time of the grants. Subsequent
vesting requires (i) the participant to remain an employee of 1st Source and
(ii) that 1st Source be profitable on an annual basis based on the determination
of the Committee. Grants under the plan for 1996 are summarized below:

NOTE J -- EMPLOYEE BENEFIT PLANS
   1st Source maintains a defined contribution money purchase pension plan
covering the majority of its employees.  Contributions to the plan are based on
2% of participants' eligible compensation.  For the years ended December 31,
1998, 1997 and 1996, total pension expense for this plan amounted to $422,000,
$433,000 and $422,000, respectively.
   1st Source also maintains a defined contribution profit sharing and savings
plan covering the majority of its employees. The plan allows eligible employees
to make contributions by salary reduction pursuant to Section 401(k) of the
Internal Revenue Code. 1st Source is required under the plan to match 100% of
participant contributions up to 4% of compensation and one-half of any
additional participant contributions up to 6% of compensation provided that 1st
Source is profitable for the respective plan year. 1st Source may also make
discretionary contributions to the plan, depending on its profitability.
Contribution expense for this plan for the years ended December 31, 1998, 1997
and 1996, amounted to $1.34 million, $1.29 million, and $1.21 million,
respectively.
   Trustcorp Mortgage Company contributes to a defined contribution plan for all
of its employees who meet the general eligibility requirements of the plan. The
contributions, which in part are based on amounts of compensation deferred by
the participants in the plan, were $78,000 in 1998, $54,000 in 1997 and $40,000
in 1996. In addition, Trustcorp Mortgage Company made discretionary
contributions of $145,000 in 1998, $103,000 in 1997, and $100,000 in 1996.
   In addition to the pension and profit sharing plans, 1st Source provides
certain health care and life insurance benefits for substantially all of their
retired employees. All of 1st Source's full-time employees become eligible for
these retiree benefits upon reaching age 55 with 20 years of credited service.
Generally, the medical plan pays a stated percentage of eligible medical
expenses reduced for any deductibles and payments made by government programs
and other group coverage. The lifetime maximum benefit payable under the medical
plan is $15,000 and $3,000 for life insurance.
   1st Source's accrued postretirement benefit cost and net periodic
postretirement benefit cost recognized in the consolidated financial statements
for the years ended December 31, 1998, 1997 and 1996 were not material.

NOTE L -- LEASES
   1st Source and its subsidiaries are obligated under operating leases for
certain office premises and equipment. The headquarters building is leased for a
remaining term of 13 years with options to renew for up to 15 additional years.
Approximately 30% of the facility is subleased to other tenants.
   At December 31, 1998, future minimum rental commitments for all
noncancellable operating leases, reduced by future minimum rentals from
subleases of $1.91 million, aggregate $17.41 million. Annual rental commitments
and sublease rentals for noncancellable operating leases (excluding operating
costs) for the five years succeeding December 31, 1998, are as follows:

NOTE M -- FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK
   1st Source and its subsidiaries are parties to financial instruments with
off-balance-sheet risk in the normal course of business to meet the financing
needs of its customers. These off-balance-sheet financial instruments include
commitments to originate, purchase and sell loans, standby letters of credit and
interest rate swaps. 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.
   1st Source's exposure to credit loss in the event of nonperformance by the
other party to the financial instrument for loan commitments and standby letters
of credit is represented by the dollar amount of those instruments. 1st Source
uses the same credit policies and collateral requirements in making commitments
and conditional obligations as it does for on-balance-sheet instruments.
   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.
   Trustcorp Mortgage Company grants 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.
   Letters of credit are conditional commitments issued by 1st Source to
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 December 1998 and 1997, 1st Source and its subsidiaries had commitments
outstanding to originate and purchase loans aggregating $362 million and $410
million, respectively. Outstanding commitments to sell loans aggregated $198
million at December 31, 1998 and $120 million at December 31, 1997. Commercial
and standby letters of credit totaled $82 million and $57 million at December
31, 1998 and 1997, respectively.
   1st Source Bank participates in interest rate swap agreements as part of its
program to manage the impact of fluctuating interest




<PAGE>   40


rates, namely with respect to floating rate loans.

   Interest rate swaps generally involve the exchange of fixed and floating rate
interest payments without the exchange of the underlying notional amount.
Notional amounts represent agreed upon amounts on which calculations of


- --Page 42--

NOTE M -- FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK -- CONCLUDED
interest payments to be exchanged are based. Notional amounts do not represent
direct credit exposures. The actual market or credit exposure of this type of
financial instrument is significantly less than the notional amount. 1st
Source's direct credit exposure is limited to the net difference between the
calculated "to be paid" and "to be received" amounts on each transaction, which
is generally netted and paid or received monthly, and the inability of the
counterparty to meet the terms of the contract. This risk is normally a small
percentage of the notional amount and fluctuates as interest rates move up and
down. Market risk to 1st Source is more directly measured by the fair values of
the interest rate swap agreements.
   At December 31, 1998, 1st Source had two outstanding amortizing interest rate
swap agreements with an aggregate notional value of $26.9 million. The
agreements have maturities of January 25, 2002 and March 25, 2001. The notional
amounts and lives of amortizing swaps change based on certain interest rate
indices. Generally, as rates fall, the notional amounts of amortizing swaps
decline more rapidly and as rates increase notional amounts decline more slowly.
Unrealized gains/(losses) based on fair value approximated $70,000 at December
31, 1998 and ($137,000) at December 31, 1997.

NOTE N -- CONCENTRATIONS OF CREDIT RISK
   Most of 1st Source's commercial and agricultural, real estate and consumer
loan activity is with customers located in north-central Indiana and southwest
lower Michigan. 1st Source's commercial loans secured by transportation and
construction equipment are with customers located throughout the United States.
Included in loans as of December 31, 1998 and 1997, are business loans to
companies in the following industries:

   Generally, these loans are collateralized by assets of the borrower. The
loans are expected to be repaid from cash flow or proceeds from the sale of
selected assets of the borrower. 1st Source requires collateral on substantially
all borrowings in these categories, which is typically the item being financed.

NOTE O -- CAPITAL ADEQUACY
   1st Source is subject to various regulatory capital requirements administered
by the federal banking agencies. Failure to meet minimum capital requirements
can initiate certain mandatory, and possibly additional discretionary actions by
regulators that, if undertaken, could have a direct material effect on 1st
Source's financial statements. Under capital adequacy guidelines and the
regulatory framework for prompt corrective action, 1st Source must meet specific
capital guidelines that involve quantitative measures of 1st Source's assets,
liabilities, and certain off-balance-sheet items as calculated under regulatory
accounting practices. 1st Source's capital amounts and classification are
subject to qualitative judgments by the regulators about components, risk
weightings, and other factors.
   Quantitative measures established by regulation to ensure capital adequacy
require 1st Source to maintain minimum amounts and ratios (set forth in the
table below) of total and Tier I capital to risk-weighted assets, and of Tier I
capi-tal to average assets. Management believes, as of De-cember 31, 1998, that
1st Source meets all capital adequacy requirements to which it is subject.
   As of December 31, 1998, the most recent notification from the federal bank
regulators categorized 1st Source Bank, the largest of 1st Source's
subsidiaries, as "well capitalized" under the regulatory framework for prompt
corrective action. To be

categorized as "well capitalized" 1st Source must maintain minimum total

REPORT OF INDEPENDENT ACCOUNTANTS 
To the Board of Directors and Shareholders of
1st Source Corporation:

   In our opinion, the accompanying consolidated statements of financial
condition and the related consolidated statements of income, shareholders'
equity and of cash flows present fairly, in all material respects, the financial
position of 1st Source Corporation and its subsidiaries at December 31, 1998 and
1997, and the consolidated results of their operations and their cash flows for
each of the three years in the period ended December 31, 1998, in conformity
with generally accepted accounting principles. These financial statements are
the responsibility of the Corporation's management; our responsibility is to
express an opinion on these financial statements based on our audits. We
conducted our audits of these statements in accordance with generally accepted
auditing standards which 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, 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 the opinion expressed above.
