                                     PART I
ITEM 1.  BUSINESS.
FIRST FINANCIAL BANCORP.
First Financial Bancorp., an Ohio corporation (Bancorp), is a bank and savings
and loan holding company that engages in the business of commercial banking, and
other permissible activities closely related to banking, through seventeen
wholly owned subsidiary institutions: First National Bank of Southwestern Ohio
(First Southwestern), Bright National Bank (Bright National), and National Bank
of Hastings (Hastings), all national banking associations, Community First Bank
& Trust (Community First), The Clyde Savings Bank Company (Clyde), both Ohio
banking corporations, Indiana Lawrence Bank (Indiana Lawrence), Citizens First
State Bank (Citizens First), Union Bank & Trust Company (Union Bank), Peoples
Bank and Trust Company (Peoples Bank), Farmers State Bank (Farmers), Vevay
Deposit Bank (Vevay), and Sand Ridge Bank (Sand Ridge), all Indiana banking
corporations, Hebron Deposit Bank (Hebron), a Kentucky banking corporation,
Fidelity Federal Savings Bank (Fidelity Federal), and Home Federal Bank, a
Federal Savings Bank (Home Federal), both federal savings banks. First Finance
Mortgage Company of Southwestern Ohio (First Finance) is Bancorp's only finance
company and First Financial Bancorp Service Corporation (Service Corporation) is
Bancorp's operations subsidiary. Bancorp provides management and similar
services for its subsidiary financial institutions. Since it does not itself
conduct any operating businesses, Bancorp must depend largely upon its seventeen
subsidiaries for funds with which to pay the expenses of its operation and, to
the extent applicable, any dividends on its outstanding shares of stock. For
further information see Note 6 of the Notes to Consolidated Financial Statements
appearing on page 19 of Bancorp's Annual Report to Shareholders, which is
incorporated by reference in response to this item.

Bancorp was formed in 1982 for the purpose of becoming the parent holding
company of First Southwestern. For additional information, please see
"Subsidiaries" on pages F-2 and F-3.

Bancorp is registered as a bank holding company under the Bank Holding Company
Act of 1956, as amended. Bancorp is also a savings and loan holding company
under the savings and loan holding company provisions of the Home Owners' Loan
Act of 1933, as amended by the Financial Institutions Reform, Recovery, and
Enforcement Act of 1989 (FIRREA). As such, Bancorp is subject to strict
regulation regarding the acquisition of additional financial institutions and
the conduct, through subsidiaries, of non-banking activities. The recent passage
of the Gramm-Leach-Bliley Act of 1999, however, has created new opportunities
for Bancorp by lifting some of the long-standing prohibitions against certain
non-banking activities (see "Regulation" on page F-3).

Bancorp faces strong competition from both financial institutions and other
non-financial organizations. Its competitors include local and regional
financial institutions, savings and loans, and bank holding companies, as well
as some of the largest banking organizations in the United States. In addition,
other types of financial institutions, such as credit unions, also offer a wide
range of loan and deposit services that are directly competitive with those
offered by Bancorp's subsidiaries. The consumer is also served by brokerage
firms and mutual funds that provide checking services, credit cards, and other
services similar to those offered by Bancorp's subsidiaries. Major stores
compete for loans by offering credit cards and retail installment contracts. It
is anticipated that competition from entities other than financial institutions
will continue to grow.

                                       F-2

The range of banking services provided by Bancorp's subsidiaries to their
customers includes commercial lending, real estate lending, consumer credit,
credit card, and other personal loan financing. First Southwestern, Community
First, Indiana Lawrence, Union Bank, Clyde, and Bright National also offer lease
financing. In addition, Bancorp's financial institutions offer deposit services
that include interest-bearing and noninterest-bearing deposit accounts and time
deposits. Most subsidiaries provide safe deposit facilities. A full range of
trust and asset management services is provided by Bancorp's subsidiaries,
excluding the savings banks, the finance company and the service corporation.
Each subsidiary retains its local identity and operates under the direction of
its own board of directors and officers.

Bancorp and its subsidiaries operate in one business segment--the financial
institutions industry. Foreign transactions are nominal. Information regarding
statistical disclosure required by Industry Guide 3 is included in Bancorp's
Annual Report to Shareholders for the year ended December 31, 1999, and is
incorporated herein by reference.

At December 31, 1999, Bancorp and its subsidiaries employed 1,871 employees.

Bancorp's executive office is located at 300 High Street, Hamilton, Ohio 45011,
and its telephone number is (513) 867-4700.

Community First was formed on November 1, 1997 as a result of the merger of two
of Bancorp's affiliates, the Citizens Commercial Bank & Trust Company and Van
Wert National Bank. On December 8, 1997, Community First purchased the assets
and assumed the liabilities of eleven branches of KeyBank National Association.
The purchase of The Union State Bank, completed on April 1, 1998, resulted in
the addition of another branch and $53 million in deposits for Community First.
On June 30, 1999, Union Trust Bank, a wholly owned subsidiary of Bancorp, merged
into Community First.

In April 1996, Bancorp acquired Farmers & Merchants Bank of Rochester,
Rochester, Indiana (F&M). Upon completion of the merger F&M was merged with
Indiana Lawrence.

In November 1995, Home Federal combined operations with Fayette Federal,
resulting in Fayette Federal operating as a division of Home Federal.

located in Indiana, it is also subject to examination by the Indiana Department
of Financial Institutions. First Finance is subject to supervision and regular
examinations by the State of Ohio Division of Consumer Finance. All depository
institutions are insured by the Federal Deposit Insurance Corporation and are
subject to the provisions of the Federal Deposit Insurance Act.

To the extent that the following information consists of summaries of certain
statutes or regulations, it is qualified in its entirety by reference to the
statutory or regulatory provisions described.

Bancorp is subject to the provisions of the Bank Holding Company Act of 1956, as
amended (the Act), which requires a bank holding company to register under the
Act and to be subject to supervision and examination by the Board of Governors
of the Federal Reserve System. As a bank holding company, Bancorp is required to
file with the Board of Governors an annual report and such additional
information as the Board of Governors may require pursuant to the Act. The Act
requires prior approval by the Board of Governors of the acquisition by a bank
holding company, or any subsidiary thereof, of 5% or more of the voting stock or
substantially all the assets of any bank within the United States. Prior to the
passage of FIRREA, it was not possible for bank holding companies, such as
Bancorp, to acquire "healthy" thrift institutions. Although such acquisitions
are now authorized, mergers between bank holding companies and thrift
institutions must be approved by the Federal Reserve Board and the Office of
Thrift Supervision. When a bank holding company acquires a thrift institution,
it is then considered a savings and loan holding company which subjects the bank
holding company to regulation and examination by the Office of Thrift
Supervision. As a bank holding company located in the State of Ohio, Bancorp is
not permitted to acquire a bank or other financial institution located in
another state unless such acquisition is specifically authorized by the statutes
of such state, as is the case in Indiana, Michigan, and Kentucky. The Act
further provides that the Board of Governors shall not approve any such
acquisition that would result in a monopoly or would be in furtherance of any
combination or conspiracy to monopolize or attempt to monopolize the business of
banking in any part of the United States, or the effect of which may be to
substantially lessen competition or to create a monopoly in any section of the
country, or that in any other manner would be in restraint of trade, unless the
anti-competitive effects of the proposed transaction are clearly outweighed in
the public interest by the probable effect of the transaction in meeting the
convenience and needs of the community to be served.

The Act and the regulations of the Board of Governors prohibit a bank holding
company and its subsidiaries from engaging in certain tie-in arrangements in
connection with any extension of credit, lease or sale of property, or
furnishing of services. The Act also imposes certain restrictions upon dealings
by affiliated banks with the holding company and among themselves, including
restrictions on interbank borrowing and upon dealings in respect to the
securities or obligations of the holding company or other affiliates.

The Act was recently amended by the Gramm-Leach-Bliley Act of 1999 (the Gramm
Act), which was enacted on November 12, 1999. The Gramm Act also repealed
portions of the Glass-Steagall Act, a piece of depression-era legislation
intended to separate banking and commerce. Under the Gramm Act, bank holding
companies that satisfy certain requirements may elect to become financial
holding companies. The Gramm Act allows financial holding companies to engage in
certain financial activities that are not permitted for bank holding companies.
The Gramm Act provides a list of activities that are "financial in nature" and
therefore permitted for financial holding companies. The list includes: lending,
investing or safeguarding money or securities; underwriting insurance or
annuities, or acting as an insurance or annuity principal, agent or broker;
providing financial or investment advice; issuing or selling interests in pools
of assets that a bank could hold; underwriting, dealing or making markets in
securities; and, subject to certain conditions, merchant banking or insurance
portfolio investing. The Board of Governors has the authority to determine that
other activities are permitted for financial holding companies, if those
activities satisfy certain criteria.

On March 13, 2000, Bancorp filed an election with the Board of Governors to
become a financial holding company in order to take advantage of the expanded
activities available to financial holding companies. The election will become
effective on April 13, 2000, unless the Board of Governors notifies Bancorp
prior to that time that the election is ineffective. The Board of Governors may
notify


   7
                                       F-5

Bancorp prior to April 13th that the election is effective. Bancorp anticipates
that its election will become effective.

The Gramm Act establishes the concept of functional regulation for bank holding
companies and financial holding companies, which means that the authority to
regulate will be determined by the nature of the activity involved. Bank holding
companies, financial holding companies and their subsidiaries will be supervised
by the regulatory agency that has traditionally regulated the particular
activity in question, while the Board of Governors will serve as an "umbrella
supervisor." Upon becoming a financial holding company, Bancorp and its
affiliates will continue to be supervised by the various regulatory agencies as
described above. However, if Bancorp expands its activities into new areas,
those activities may be subject to the supervision of regulatory agencies that
have not previously supervised Bancorp's activities.

The earnings of banks, and therefore the earnings of Bancorp (and its
subsidiaries), are affected by the policies of regulatory authorities, including
the Board of Governors of the Federal Reserve System. An important function of
the Federal Reserve Board is to regulate the national supply of bank credit in
an effort to prevent recession and to restrain inflation. Among the procedures
used 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 procedures are used in varying combinations to influence overall growth
and distribution of bank loans, investments and deposits, and their use also may
affect interest rates charged on loans or paid for deposits.

Monetary policies of the Federal Reserve Board 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. The effect, if any, of such policies upon the
future business and earnings of Bancorp cannot accurately be predicted.

Bancorp makes no attempt to predict the effect on its revenues and earnings of
changes in general economic, industrial, and international conditions or in
legislation and governmental regulations.
