Thrift Plan and Trust Administrative Committee
First Financial Bancorp

We have audited the accompanying statements of net assets available for benefits
of the First Financial Bancorp Thrift Plan and Trust as of December 31, 2001 and
2000, and the related statements of changes in net assets available for benefits
for the years then ended. These financial statements are the responsibility of
the Plan's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards 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. An audit
also includes assessing the accounting principles used and significant estimates
made by management as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the First
Financial Bancorp Thrift Plan and Trust at December 31, 2001 and 2000, and
changes in net assets available for benefits for the years then ended in
conformity with accounting principles generally accepted in the United States.

Our audits were performed for the purpose of forming an opinion on the financial
statements taken as a whole. The accompanying supplemental schedules of assets
held as of December 31, 2001, and reportable transactions for the year then
ended, are presented for the purposes of complying with the Department of
Labor's Rules and Regulations for Reporting and Disclosure under the Employee
Retirement Income Security Act of 1974, and are not a required part of the basic
financial statements. The Fund Information in the statement of net assets
available for benefits and the statement of changes in net assets available for
benefits is presented for purposes of additional analysis rather than to present
the net assets available for benefits and changes in net assets available for
benefits of each fund. The supplemental schedules and Fund Information have been
subjected to the auditing procedures applied in our audits of the basic
financial statements and, in our opinion, are fairly stated in all material
respects in relation to the financial statements taken as a whole.

1. DESCRIPTION OF THE PLAN

The following brief description of the First Financial Bancorp Thrift Plan and
Trust (the Plan) is provided for general information purposes only. Participants
should refer to the summary plan description for more information.

First Financial Bancorp (Bancorp) is the sponsor of the Plan.

GENERAL

The Plan is a defined-contribution plan, qualified under Section 401 of the
Internal Revenue Code and is subject to the provisions of the Employee
Retirement Income Security Act of 1974 (ERISA). The Plan covers substantially
all employees of First Financial Bancorp (Plan Sponsor) and affiliates who have
attained at least one year of service and are age twenty-one or older. The Plan
is subject to the provisions of Section 401(k) of the Internal Revenue Code
whereby the participants' discretionary contributions would not be reportable as
compensation for federal and state income tax purposes. The Plan is a single
plan of a controlled group as defined in Code Sections 414(b) and 414(c).

FUNDING

Employer contributions to the Plan are equal to 50 percent of the employee's
contribution limited to three (3) percent of the employee's base salary.
Employer contributions are invested in the First Financial Bancorp Common Stock
Fund and are fully vested upon contribution to the Plan. Although the sponsor
has not expressed any intention to do so, it has the right under the Plan to
discontinue contributions at any time and terminate the Plan, subject to
provisions set forth in ERISA.

Participants may elect to make contributions to the Plan of up to 12 percent of
their eligible salary on a before-tax basis. Prior to February 1, 1986,
participants were permitted to contribute certain amounts on an after-tax basis.
All contributions are fully vested when made and can be made to any of the
investment options.







                                                                               6

                    Notes to Financial Statements (continued)



1. DESCRIPTION OF THE PLAN (CONTINUED)

PARTICIPATING CORPORATIONS

The terms of the Plan provide that any corporation, which is or becomes a
subsidiary of Bancorp may, with consent of Bancorp, adopt this plan for those
employees which the subsidiary determines shall be eligible.

Effective January 1, 2000, the Plan was amended to admit the employees of Sand
Ridge Bank and Hebron Deposit Bank, both wholly-owned subsidiaries of Bancorp.

BENEFIT PAYMENTS

Participants who have withdrawn all of their after-tax contributions may elect
to withdraw employer contributions and the earnings of their accounts. Employer
contributions withdrawn are limited to those made more than eight plan quarters
prior to the quarter in which the withdrawal is being made. Such a withdrawal
suspends the participant's right to make contributions for one year.

Active employees under 59-1/2 years of age may withdraw before-tax savings only
if the participant can prove "financial hardship" as defined by the Internal
Revenue Service. If a participant is an active employee over 59-1/2 years of
age, he or she may withdraw any amount of before-tax savings for any reason. Any
distribution of before-tax funds results in a one-year suspension of
participation in the Plan. Withdrawal of funds must be made in the following
sequences: after-tax contributions; earnings on participants' after-tax
contributions; employer contributions; and before-tax contributions.

PARTICIPANTS' ACCOUNTS

Earnings are allocated on beginning account balances less any withdrawals during
the quarter. A participant may elect to withdraw all or any part of his or her
after-tax savings from the Plan. Such withdrawal suspends the participant's
rights to make future contributions for six months.




                                                                               7

                    Notes to Financial Statements (continued)



1. DESCRIPTION OF THE PLAN (CONTINUED)

PARTICIPANTS' ACCOUNTS (CONTINUED)

Employee contributions to the Plan may be allocated, in 5 percent increments,
among any of the eight available funds, as follows:

      The Savings Fund invests primarily in the Goldman Sachs Prime Corporate
      Money Fund, which holds a diversified portfolio of high-grade short-term
      debt obligations that have minimal credit risk. The fund seeks to maintain
      a net asset value of $1.00 per unit. The investment objective is to
      provide income, preserve capital, and provide liquidity.

      The Fixed Income Fund invests primarily in the Fixed Income Fund -
      Collective Investment Fund for Pension and Profit Sharing Trusts of First
      National Bank of Southwestern Ohio, which holds a diversified portfolio of
      U.S. Government bonds, notes, agencies, and high quality corporate bonds.
      The fund only purchases bonds with a credit rating of A or better and a
      short to intermediate term maturity. The objectives of the Fixed Income
      Fund are to provide a reasonable level of income and stability of capital.

      The Balanced Fund divides its investments between the Equity Fund -
      Collective Investment Fund for Pension and Profit Sharing Trusts of First
      National Bank of Southwestern Ohio and the Fixed Income Fund - Collective
      Investment Fund for Pension and Profit Sharing Trusts of First National
      Bank of Southwestern Ohio. The objectives of the Balanced Fund include
      providing current income, conserving capital, and long-term growth
      capital. The Balanced Fund's risk is generally considered to be more than
      the Savings and Fixed Income Funds, but less than the Equity Fund and the
      First Financial Bancorp Common Stock Fund.

      The Equity Fund invests in the Equity Fund - Collective Investment Fund
      for Pension and Profit Sharing Trusts of First National Bank of
      Southwestern Ohio, which holds a diversified portfolio of common stocks.
      The investment objective is long-term growth of capital.

      The First Financial Bancorp Common Stock Fund invests primarily in First
      Financial Bancorp Common Stock. The investment objective is long-term
      growth of capital. This fund is generally considered to be the riskiest
      investment alternative offered because of the absence of diversification.









                                                                               8

                    Notes to Financial Statements (continued)



1.  DESCRIPTION OF THE PLAN (CONTINUED)

PARTICIPANTS' ACCOUNTS (CONTINUED)

      The International Fund invests primarily in international mutual funds,
      which invest in stocks of established and emerging foreign markets.
      Performances of foreign stocks are closely tided to the economic,
      political, and environmental condition of a country and region.

      The Vanguard 500 Index Fund invests primarily in the Vanguard 500 Index,
      which seeks investment results that correspond with the price and yield
      performance of the S&P 500 index. Though the fund seeks to match the S&P
      500 index, its performance typically can be expected to fall short by a
      small percentage representing operating costs.

      The Small Capital Fund invests primarily in small cap mutual funds, which
      invest in stock of emerging companies whose market value generally is
      below $2 billion. These stocks tend to be more volatile and may perform
      differently than large cap stocks.

PLAN TERMINATION

In the event of termination, the net assets will be distributed to participants
and beneficiaries in proportion to their respective account balances, which
become 100 percent vested.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

USE OF ESTIMATES

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires management to make estimates
and assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

VALUATION OF INVESTMENTS

Separate trust accounts at First National Bank of Southwestern Ohio, a
wholly-owned subsidiary of Bancorp, are used to hold and invest the Plan's
assets. Investments are stated at fair values based on quoted closing market
prices obtained by the trustee from published market data. Security transactions
are recorded on the trade date.





                                                                               9

3. INVESTMENTS

The Plan uses the average cost method for determining the cost of securities
sold when determining realized gains and losses. The Plan's investments
(including investments bought, sold, and held during the year) appreciated in
fair value by $1,240,110 in 2001 and depreciated by $5,984,107 in 2000 as
follows:

4. INCOME TAX STATUS

The Plan has received a determination letter from the Internal Revenue Service
dated March 3, 1995, stating that the Plan is qualified under section 401(a) of
the Internal Revenue Code (the "Code") and, therefore, the related trust is
exempt from taxation. Once qualified, the Plan is required to operate in
conformity with the Code to maintain its qualification. However, the Plan has
been amended and restated subsequent to the date of the determination letter.
The Plan Administrator believes the Plan, as amended and restated, is being
operated in compliance with the applicable requirements of the Code and,
therefore, believes that the Plan is qualified and the related trust is tax
exempt.

5. TRANSACTIONS WITH PARTIES-IN-INTEREST

Administrative and other service fees are paid by the Plan Sponsor. The Trust is
not charged for administrative services performed on its behalf by First
Financial Bancorp.

The Trust invests in common stock of the Plan Sponsor.

An affiliate of the Plan Sponsor is the Plan Trustee.
