ITEM 1.   BUSINESS

(a) GENERAL DEVELOPMENT OF BUSINESS
Horizon Bancorp, a registered bank holding company organized under the laws of
the State of Indiana on April 26, 1983, (Registrant), became the parent
corporation and sole shareholder of The First Merchants National Bank of
Michigan City pursuant to a plan of reorganization effective October 31, 1983.
Prior to October 31, 1983, the Registrant conducted no business and had only
nominal assets necessary to complete the plan of reorganization.

On October 1, 1986 the Registrant issued 399,340 shares of its common stock in
exchange for all of the common stock of Citizens Michiana Financial Corporation
in connection with mergers of such companies and their subsidiaries. Subsequent
to the merger, the Registrant remains a one-bank holding company with a
wholly-owned subsidiary, Horizon Bank, N.A. (Bank) and Bank's wholly-owned
subsidiaries, IMS Investment Management, N.A. (IMS) and Phoenix Insurance
Services, Inc. (Phoenix) and non-bank subsidiaries, HBC Insurance Group
(Insurance Company) and The Loan Store, Inc., (Loan Store).

(b) FINANCIAL INFORMATION ABOUT INDUSTRY SEGMENTS
The Registrant, Bank and its subsidiaries are engaged in the commercial and
retail banking business, investment management services, commercial and personal
property and casualty insurance services, retail lending and insurance credit
life sales. Refer to Item 1(e) and Item 6 for information pertaining to
Registrant's banking business.

(c) NARRATIVE DESCRIPTION OF BUSINESS
The Registrant's business is that incident to its 100% ownership of Bank, Loan
Store and the Insurance Company. The main source of funds for the Registrant is
dividends from Bank. Bank was chartered as a national bank association in 1873
and has operated continuously since that time. Bank , whose deposits are insured
by the Federal Deposit Insurance Corporation to the extent provided by law, is a
full-service commercial bank offering a broad range of commercial and retail
banking services, corporate and individual trust and agency services, commercial
and personal property and casualty insurance services and other services
incident to banking. Bank maintains four facilities located within LaPorte
County, Indiana and four facilities located in Porter County, Indiana. At
December 31, 1998, Bank had total assets of $408,443,000 and total deposits of
$322,401,000. Aside from the stock of Bank, Insurance Company and Loan Store,
the Registrant's only other significant assets are cash and cash equivalents
totaling approximately $2,007,000, investment securities totaling approximately
$377,000 and taxes receivable of approximately $287,000 at December 31, 1998.

The business of the Registrant, Bank, IMS, Phoenix, Insurance Company and Loan
Store is not seasonal to any material degree.

No material part of the Registrant's business is dependent upon a single or
small group of customers, the loss of any one or more of whom would have a
materially adverse effect on the business of the Registrant. Revenues from loans
accounted for 71% in 1998, 72% in 1997, and 68% in 1996 of the total
consolidated revenue. Revenues from investment securities accounted for 13% in
1998, 14% in 1997 and 15% in 1996 of total consolidated revenue.

The Registrant has no employees and there are approximately 198 full and
part-time persons employed by Bank, IMS and Loan Store as of December 31, 1998.

A high degree of competition exists in all major areas where the Registrant
engages in business. Bank's primary market consists of LaPorte County, Indiana,
Porter County, Indiana, and Berrien County, Michigan. Bank competes with
commercial banks located in the home county and contiguous counties in Indiana
and Michigan, as well as with savings and loan associations, consumer finance
companies, and credit unions located therein. To a more moderate extent, Bank
competes with Chicago money center banks, mortgage banking companies, insurance
companies, brokerage houses, other institutions engaged in money market
financial services, and certain government agencies.

The Insurance Company offers credit life and accident and health insurance. The
Loan Store, Inc. is engaged in the business of retail lending and operates three
facilities in Northwest Indiana. The net income generated from the Insurance
Company and the Loan Store are not significant to the overall operations of the
Registrant.

                                                                               3

REGULATION
The earnings and growth of the banking industry and the Registrant are affected
not only by the general economic conditions, but also by the credit policies of
monetary authorities, particularly the Federal Reserve System. An important
function of the Federal Reserve System is to regulate the national supply of
bank credit in order to contest recessionary trends and curb inflationary
pressures. Among the instruments of monetary policy used by the Federal Reserve
System to implement these objectives are open market operations in U.S.
Government securities, changes in the discount rate on member bank borrowings,
and changes in reserve requirements against member bank deposits. These means
are used in varying combinations to influence overall growth of bank loans,
investments and deposits and may also affect interest rates charged on loans or
paid on deposits. The monetary policies of the Federal Reserve System have had a
significant effect on the operating results of commercial banks in the past and
are expected to continue to do so in the future. Because of changing conditions
in the national and international economy and the money markets, and as a result
of actions by monetary and fiscal authorities, including the Federal Reserve
System, interest rates, credit availability and deposit levels may change due to
circumstances beyond the control of the Registrant or Bank.

The Registrant, as a bank holding company, is subject to regulation under the
Bank Holding Company Act of 1956, as amended (Act), and is registered with the
Board of Governors of the Federal Reserve System (Board of Governors). Under the
Act, the Registrant is required to obtain prior approval of the Board of
Governors before acquiring direct ownership or control of more than 5% of the
voting shares of any bank. With certain exceptions, the Act precludes the
Registrant from acquiring direct or indirect ownership or control of more than
5% of the voting shares of any company which is not a bank and from engaging in
any business other than that of banking, managing and controlling banks, or
furnishing services to its subsidiary. The Registrant may engage in, and may own
shares of companies engaged in, certain activities found by the Board of
Governors to be so closely related to banking as to be a proper incident
thereto.

The Registrant is required to file annual reports of its operations with the
Board of Governors and such additional information as they may require pursuant
to the Act, and the Registrant and Bank are subject to examination by the Board
of Governors. Further, the Registrant and Bank are prohibited from engaging in
certain tie-in arrangements with respect to any extension of credit or provision
of property or services.

The Board of Governors also possesses the authority through cease and desist
powers to regulate parent holding company and nonbank subsidiaries where action
of a parent holding company or its nonbank subsidiaries constitutes a serious
threat to the safety, soundness or stability of a subsidiary bank. Federal bank
regulatory agencies also have the power to regulate debt obligations issued by
bank holding companies. Included in these powers is the authority to impose
interest ceilings and reserve requirements on such debt obligations.

The acquisition of banking subsidiaries by bank holding companies is subject to
the jurisdiction of, and requires the prior approval of, the Federal Reserve
and, for institutions resident in Indiana, the Indiana Department of Financial
Institutions. Bank holding companies located in Indiana are permitted to acquire
banking subsidiaries throughout the state, subject to limitations based upon the
percentage of total state deposits of the holding company's subsidiary banks.
Further, Indiana law permits interstate bank holding company acquisitions on a
reciprocal basis, subject to certain limitations. Beginning July 1, 1992,
Indiana law permits the Registrant to acquire banks, and be acquired by bank
holding companies, located in any state in the country which permits reciprocal
entry by Indiana bank holding companies.

The Registrant, Bank, IMS, Phoenix, Insurance Company and Loan Store are
"affiliates" within the meaning of the Federal Reserve Act. The Federal Reserve
Act and the Federal Deposit Insurance Act limit the amount of the Bank's loans
or extensions of credit to affiliates, its investments in the stock or other
securities thereof, and its taking of such stock or securities as collateral for
loans to any borrower.

Bank, as a national bank, is regulated and regularly examined by the Office of
the Comptroller of the Currency (OCC). In addition to certain statutory
limitations on the payment of dividends, approval of the OCC is required for any
dividend to the Registrant by Bank if the total of all dividends, including any
proposed dividend, declared by Bank in any calendar year exceeds the total of
its net profits (as defined by the OCC) for that year combined with its retained
net profits for the preceding two years, less any required transfers to surplus.

                                                                               4

The Federal Reserve Board implemented risk-based capital requirements for banks
and bank holding companies in December, 1988. The risk-based capital
requirements have little effect on the Registrant because existing capital is in
excess of the requirements. (See additional discussion in Management's
Discussion and Analysis in Registrant's Annual Report to Shareholders, Exhibit
13.)

         The decrease in nonaccrual loans in 1995 is primarily due to three
         loans which were returned to an accruing basis. These loans had
         sustained required payment performance over the last six months or
         longer.
                                                                               7

          the loans had been current, in accordance
          with their original terms and had been

         Discussion of Nonaccrual Policy

         From time to time, the Bank obtains information which may lead
         management to believe that the collection of interest may be doubtful
         on a particular loan. In recognition of such, it is management's policy
         to convert the loan from an "earning asset" to a nonaccruing loan.
         Further, it is management's policy to place a commercial loan on a
         nonaccrual status when delinquent in excess of 90 days, unless the Loan
         Committee approves otherwise. All loans placed on nonaccrual status
         must be reviewed by the officer responsible for the loan, the senior
         lending officer and the loan review officer. The loan review officer
         monitors the loan portfolio for any potential problem loans.

    2.  Potential Problem Loans

         Loans where there are serious doubts as to the ability of the borrower
         to comply with present loan repayment terms, and not included in
         Section 1 above, amount to $341,000 at December 31, 1998. Loan
         customers included in this category are having financial difficulties
         at the present time and may need adjustments in their repayment terms.
         Payments are anticipated or collateral or guarantees are available to
         reduce any possible loss. These loans and potential loss exposure have
         been considered in management's analysis of the adequacy of the
         allowance for loan losses. Consideration was given to loans classified
         for regulatory purposes as loss, doubtful, substandard or special
         mention that have not been disclosed in Section 1 above. Management
         believes that these loans do not represent or result from trends or
         uncertainties which management reasonably expects will materially
         impact future operating results, liquidity or capital resources, or
         management believes that these loans do not represent material credits
         about which management is aware of any information which causes
         management to have serious doubts as to the ability of such borrowers
         to comply with the loan repayment terms.

         None

    4.   Loan Concentrations

         As of December 31, 1998 there are no significant concentrations of

         III above.

         The increase in the provision for loan losses in 1997 was the result of
         increased charge-offs identified in the installment loan portfolio,
         specifically direct consumer loans and credit cards. The volume of
         charge-offs in these portfolios was beginning to reduce in late 1998.
         Management expects charge-offs in all other portfolios to remain at the
         1997 levels.

                                                                               9

                ===================================================================================================================



         The increase in the reserve allocation for installment loans from 1995
         to 1996 is primarily the result of the change in methodology for the
         historical portion of the allowance calculation. In 1996, the Bank
         began using the industry average charge-off rate instead of the Bank's 
         historical charge-off rate which was used in previous years. This
         change in methodology resulted in a $325 increase in the portion of the
         allowance allocated to installment loans in 1996.

         In 1998, $277 thousand of the increase in the allowance allocated to
         installment loans is related to loans originated at the Loan Store. The
         underwriting standards of the subsidiary have been evaluated and
         strengthened in 1998. Management expects the current allocation of the
         allowance to continue through 1999. The remaining increase in the
         allocation associated with installment loans is related to the
         methodology adopted in 1996 in which the higher of the Bank or the
         industry average charge-off rate is utilized. The industry average
         historical rate was higher than Banks historical charge-off rate in
         1998 resulting in an additional allocation to the installment loan
         portfolio of $160 thousand.
