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 subsidiary, IMS Investment
        Management, N.A. (IMS) 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, 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, and other services
        incident to banking. Bank maintains five facilities located exclusively
        within LaPorte County, Indiana and four facilities located in Porter
        County, Indiana. At December 31, 1997, Bank had total assets of
        $359,751,000 and total deposits of $264,413,000. 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
        $864,000, investment securities totaling approximately $401,000 and
        taxes receivable of approximately $1,323,000 at December 31, 1997.

         The business of the Registrant, Bank, IMS, 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 72% in 1997, 68% in 1996,
        and 67% in 1995 of the total consolidated revenue. Revenues from
        investment securities accounted for 14% in 1997, 15% in 1996 and 20% in
        1995 of total consolidated revenue.

         The Registrant has no employees and there are approximately 180 full
         and part-time persons employed by Bank , IMS and Loan Store as of
         December 31, 1997.

         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 four 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.

         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, 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.

         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. The increase in nonaccrual loans in 1994 is due primarily to
    three loans for approximately $1,500,000, secured by real estate and
    having common ownership.
    These loans were placed on nonaccrual in April and May of 1994.

          period on nonaccrual loans outstanding as
          of December 31, 1997.



         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 $44,000 at December 31, 1997. 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.

    3.   Foreign outstandings

         None

    4.   Loan Concentrations

         As of December 31, 1997 there are no significant concentrations of
         loans exceeding 10% of total loans other than those disclosed in Item
         III above.

         there are no other interest-bearing assets as of December 31, 1997
         which would be required to be disclosed under Item III C.1 or 2 if such
         assets were loans.

         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. Management
         believes that by mid-1998, the volume of charge-offs in these
         portfolios will begin to reduce and that a more normal provision will
         be re-instated. Management expects charge-offs in all other portfolios
         to remain at the 1997 levels.

         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 methodolgy resulted in a $325 increase in the portion of
         the allowance allocated to installment loans in 1996.
