FORM 10-K CROSS REFERENCE INDEX

Part I

Item 1. Business.

First Financial Bancorp.

First Financial Bancorp., an Ohio corporation (Bancorp), was formed in 1982. Bancorp is a bank and savings and loan holding company headquartered in Hamilton, Ohio.

Bancorp engages in the business of commercial banking and other banking and banking-related activities through its wholly owned subsidiary institutions: First Financial Bank, National Association (First Financial), a national banking association, 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), Heritage Community Bank (Heritage), and Sand Ridge Bank (Sand Ridge), all Indiana banking corporations, and Fidelity Federal Savings Bank (Fidelity Federal), a federal savings bank. First Financial Bancorp Service Corp. (Service Corp) is Bancorp’s operations subsidiary which serves Bancorp’s subsidiaries in regard to items processing, deposit services, loans operations, and similar processing functions. First Financial Capital Advisors LLC (FFCA) is Bancorp’s registered investment advisory company created to serve as investment advisor to The Legacy Funds Group, Bancorp’s proprietary mutual funds introduced in May of 2002, and assists Bancorp’s subsidiaries with the investment management of trust assets. Two other subsidiaries of Bancorp are First Financial (OH) Statutory Trust I (Statutory Trust I) and First Financial (OH) Statutory Trust II (Statutory Trust II) which were established to facilitate raising Tier I capital in the form of corporation-obligated mandatorily redeemable capital securities of subsidiary trust — commonly referred to as Trust Preferred Securities. 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 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 29 of Bancorp’s Annual Report to Shareholders, which is incorporated by reference in response to this item.

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. 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 bank, the service corporation, and the statutory trust companies. Each subsidiary retains its local identity and operates under the direction of its own board of directors and officers.

     Bancorp makes a variety of loans to individuals and businesses. Loan interest and fees make up the majority of Bancorp’s income, approximately 66% in 2003. The principal types of lending that Bancorp engages in are real estate, commercial and consumer. Real estate loans are loans secured by a mortgage lien on the real property of the borrower and includes both residential property (one to four family residential housing units) and commercial property (owner-occupied and investor income producing real estate, such as apartments, shopping centers, office buildings). The majority of residential real estate loans made by Bancorp’s subsidiary banks conform to secondary market loan standards. The credit underwriting standards adhere to a certain level of documentation,

verifications, valuation, and the borrower’s overall credit performance. The underwriting of these loans includes an evaluation of these and other pertinent factors prior to the extension of credit. These standards help in the management of the credit risk elements.

Commercial real estate loans are also secured by a mortgage lien on the real property. The credit underwriting for both owner-occupied and investor income producing real estate loans involves detailed market analysis, historical and projected cash flow analysis, appropriate equity margins, assessment of lessees and lessors, type of real estate and other analysis. Risk of loss is managed by adherence to a standard loan policy that establishes certain levels of performance prior to the extension of a loan to the borrower. Diversification in market areas within Bancorp’s service area and a diversification by industry are other means by which the risk is managed at Bancorp.

Commercial loans are made to all types of businesses, from the local retail outlet for its seasonal sales needs to the manufacturing company for new equipment financing. Bancorp’s subsidiaries work with rapidly growing businesses to meet both their working capital needs while at the same time providing long-term financing for their acquisition and expansion plans. Many of our community banks work closely with agricultural customers to provide financing for new farm implements, livestock, and crop production. Credit risk is managed by a standard loan policy, established authorized credit limits, and the diversification of market area and industries. The overall strength of the borrower is evaluated through the credit underwriting process and includes a review of historical and projected cash flows, historical financial performance, financial strength of the principals and guarantors, and collateral values, where applicable.

Installment loans primarily include loans made to individuals. Types of loans include new and used vehicle loans, second mortgages on residential real estate, and unsecured loans to individuals. Risk elements in the installment loan portfolio are focused on the ability of the borrower to repay. Some security is provided through liens on automobile titles and second mortgage liens, where applicable. Installment loans are generally smaller dollar amounts than other types of lending and are made to a large number of customers. Both factors help provide diversification of the portfolio. Economic conditions that affect consumers in Bancorp’s markets have a direct impact on the credit quality of these loans. Higher levels of unemployment, lower levels of income growth and weaker economic growth are factors that can adversely impact installment loan credit quality. These loans are generally underwritten to affiliate standards, which focus on the borrower’s cash flow and credit history.

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, 2003, and is incorporated herein by reference.

At December 31, 2003, Bancorp and its subsidiaries employed 1,795 employees.

Bancorp’s executive office is located at 300 High Street, Hamilton, Ohio 45011, and the telephone number is (513) 867-5447. Bancorp makes available, free of charge, its annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and all amendments to those reports, as soon as reasonably practicable after filing with the Securities and Exchange Commission, through its website, www.ffbc-oh.com under the “Investor Information” link, click on “SEC Filings”.

Subsidiaries
The following table lists each of Bancorp’s subsidiaries, their acquisition dates, the number of offices that each subsidiary has, their total deposits, and the number of ATMs owned by each subsidiary:

Historically, Bancorp has operated under a community banking philosophy. In the past, this philosophy was implemented by small, multiple banking subsidiaries. In January of 2001, Bancorp began a process of regionalization and market expansion, known as “Project Renaissance,” the purpose of which was to reduce the number of banking subsidiaries to four and to convert each banking subsidiary to a common data processing system. Bancorp initiated this plan to gain efficiencies through consolidation, to provide a structure with a smaller number of subsidiaries that could more easily be managed, and to better position the company for growth, for instance by reducing operational burdens on certain employees and enabling them to focus more on customer sales and service. To date, all data processing conversions have been completed and three of the four regional financial institutions have been formed.

In November 2001, Bancorp completed the first consolidation of “Project Renaissance” by merging four of its wholly owned subsidiaries, Union Bank & Trust Company, Peoples Bank and Trust Company, Farmers State Bank, and Vevay Deposit Bank, to form Heritage.

On December 31, 2001, Community First purchased certain assets and assumed certain liabilities of a division of Blue River Bancshares operating under the name First Community Bank of Fort Wayne, Indiana. This acquisition allowed Community First to expand into the Fort Wayne market.

In July 2002, Bancorp formed its second regional financial institution by merging two of its wholly owned subsidiaries, First National Bank of Southwestern Ohio and Hebron Deposit Bank, to form First Financial.

Bancorp merged three of its wholly owned subsidiaries, Bright National Bank, National Bank of Hastings, and Sand Ridge, in November 2002. Sand Ridge is the surviving subsidiary and became the third regional financial institution to be formed under “Project Renaissance.”

In 2004, Bancorp will begin the process of forming its fourth and final regional financial institution, subject to regulatory approval. This final stage of regionalization is expected to involve the consolidation of Citizens First, Clyde, Fidelity Federal and Indiana Lawrence into Community First.

Bancorp still believes in the philosophy of community banking. Upon completion of “Project Renaissance,” Bancorp will be an alliance of regionally based community banks — each with its own identity, unique history, and separate responses to local market needs. This consolidation process will afford Bancorp’s subsidiaries the opportunity to offer more products, such as cash management services, expanded trust services, private banking, and annuity products. Bancorp’s goal in this process is to achieve efficiencies of size and standardization, while maintaining each subsidiary’s customer relationships.

Market and Competitive Information

Bancorp, through its regionalization plan “Project Renaissance,” has focused its subsidiary group around four broad geographic regions. One region, covered by Heritage, serves Southeastern Indiana. A second region, covered by First Financial, consists of a Southwestern Ohio and Northern Kentucky market. The third region, covered by Sand Ridge, serves Northwestern Indiana and Southern Michigan. The fourth group of subsidiaries, consisting of Citizens First, Clyde, Fidelity Federal, Indiana Lawrence and Community First, focuses on Northwestern Ohio and Central to Northeastern Indiana. The market areas include many different types of activities, such as manufacturing, agriculture, education, healthcare, and service based economies. Within these regions, growth is projected to continue in key demographic groups and in levels of population. Core demographic measures Bancorp evaluates include income levels, median household income, and population growth within key segments. The Midwest markets that Bancorp serves have experienced a slowing and more uncertain economy from 2001 through 2003 as indicated by such items as increased unemployment rates and personal bankruptcy growth rates in Ohio and Indiana. These economic factors continue to have a negative impact on Bancorp’s business.

Bancorp, as a mid-sized regional bank holding company, believes it is well positioned to compete in these markets. Smaller than super-regional and multi-national bank holding companies, Bancorp believes it can meet the needs of its markets through a local decision making network of local management and affiliate boards of directors. Bancorp believes it is better positioned to compete for business than some smaller banks that may have size or geographic limitations. Bancorp’s strategy is to differentiate itself by providing superior customer service and delivering innovative products in its markets. Bancorp’s targeted customers include individuals and small to medium sized businesses

within the geographic region of the subsidiary branch network. Through Bancorp’s subsidiaries’ delivery system of branches, automated teller machines (ATM’s), internet banking, and telephone based transactions, we meet the needs of our customers in an ever-changing marketplace.

Bancorp faces strong competition from 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, 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.

Regulation

First Financial, as a national banking association, is subject to supervision and regular examination by the Comptroller of the Currency. Community First and Clyde, as Ohio state chartered banks, are subject to supervision and regular examination by the Superintendent of Banks of the State of Ohio. First Financial, Community First, Clyde, Heritage, and Sand Ridge are members of the Federal Reserve System and, as such, are subject to the applicable provisions of the Federal Reserve Act. Community First, Heritage, and Sand Ridge are also subject to regular examination by the Board of Governors of the Federal Reserve System (Federal Reserve Board). Indiana Lawrence, Citizens First, Heritage, and Sand Ridge, as Indiana state chartered banks, are subject to supervision and regular examination by the Indiana Department of Financial Institutions. Fidelity Federal, as a federal savings bank, is subject to supervision and regular examination by the Office of Thrift Supervision. Since Fidelity Federal is located in Indiana, it is also subject to examination by the Indiana Department of Financial Institutions. All depository institutions are insured by the Federal Deposit Insurance Corporation and are subject to the provisions of the Federal Deposit Insurance Act.

As a bank and savings and loan holding company, Bancorp is subject to the provisions of the Bank Holding Company Act of 1956, as amended (the Act). The Act requires bank holding companies to register under the Act and to be subject to supervision and examination by the Federal Reserve Board. Bancorp is required to file with the Federal Reserve Board an annual report and such additional information as the Federal Reserve Board may require pursuant to the Act. The Act requires prior approval by the Federal Reserve Board of the acquisition of 5% or more of the voting stock or substantially all the assets of any bank within the United States. Following the passage of the Financial Institutions Reform, Recovery, and Enforcement Act of 1989, bank holding companies may acquire thrift institutions subject to approval by the Federal Reserve Board and the Office of Thrift Supervision and ongoing regulation and examination by the Office of Thrift Supervision. As a bank and savings and loan holding company located in the State of Ohio, Bancorp is not permitted to acquire a bank 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 Federal Reserve Board 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 Federal Reserve Board 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 the securities or obligations of the holding company or other affiliates.

The Act was amended by the Gramm-Leach-Bliley Act of 1999 (GLBA), which was enacted on November 12, 1999. The GLBA also repealed portions of the Glass-Steagall Act, a piece of depression-era legislation intended to separate banking and commerce. Under the GLBA, bank holding companies that satisfy certain requirements may elect to become financial holding companies. The GLBA allows financial holding companies to engage in certain activities that are “financial in nature” and that are not permitted for bank holding companies. Bancorp initially elected to become a financial holding company in March 2000 and then withdrew its election in July 2002. Bancorp’s decision to remain a bank and savings and loan holding company was due to the more stringent regulatory requirements imposed upon financial holding companies and to the fact that Bancorp’s strategic plans did not include utilizing the expanded activities available to financial holding companies.

The earnings of banks, and therefore the earnings of Bancorp (and its subsidiaries), are affected by the policies of regulatory authorities, including the Federal Reserve Board. 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.

Compliance Matter

On July 2, 2002, Community First, which represents 17.22% of Bancorp’s December 31, 2003, total assets, entered into an agreement with the Federal Reserve Board regarding the steps necessary to bring the bank into compliance with the Bank Secrecy Act. Community First has fully satisfied the provisions of the agreement, and, as a result, the agreement was terminated by the Federal Reserve Board effective January 29, 2004.
