             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Participants and Administrator of
FirstBank 401(k) Retirement Plan
for Residents of Puerto Rico


In our opinion, the accompanying statements of net assets available for benefits
and the related statement of changes in net assets available for benefits
present fairly, in all material respects, the net assets available for benefits
of FirstBank 401(k) Retirement Plan for Residents of Puerto Rico (the "Plan") at
December 31, 2003 and 2002, and the changes in net assets available for benefits
for the year ended December 31, 2003 in conformity with accounting principles
generally accepted in the United States of America. 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 of these statements in accordance with
the standards of the Public Company Accounting Oversight Board (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, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of Assets (Held
at End of Year) is presented for the purpose of additional analysis and is not a
required part of the basic financial statements but is supplementary information
required by the Department of Labor's Rules and Regulations for Reporting and
Disclosure under the Employee Retirement Income Security Act of 1974. This
supplemental schedule is the responsibility of the Plan's management. The
supplemental schedule has been subjected to the auditing procedures applied in
the audit of the basic financial statements and, in our opinion, is fairly
stated in all material respects in relation to the basic financial statements
taken as a whole.

FIRSTBANK 401(K) RETIREMENT PLAN FOR RESIDENTS OF PUERTO RICO
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2003 AND 2002
--------------------------------------------------------------------------------


1.      DESCRIPTION OF THE PLAN

        REPORTING ENTITY

        The accompanying financial statements include the assets of the
        FirstBank 401(k) Retirement Plan for Residents of Puerto Rico (the
        "Plan") sponsored by FirstBank Puerto Rico (the "Bank") for its Puerto
        Rico employees only.

        The following description of the Plan provides only general information.
        Participants should refer to the Plan agreement for a more complete
        description of the Plan's provisions.

        GENERAL

        The Plan is a defined contribution plan, which became effective in 1965,
        and was amended in 1977, to comply with the requirements of the Employee
        Retirement Income Security Act of 1974 (ERISA) and as of January 1,
        1985, to comply with the requirements of the Retirement Equity Act of
        1984 (REACT). Accordingly, it is subject to the provisions of the
        Employee Retirement Income Security Act of 1974 (ERISA). Effective
        September 1, 1991, the Plan was further amended to become a savings plan
        under the provisions of the Puerto Rico Internal Revenue Code Section
        1165(e).

        All full-time employees of the Bank and its wholly owned subsidiaries
        are eligible to participate in the Plan after completion of one year of
        service.

        CONTRIBUTIONS

        Participants are permitted to contribute up to 10% of their pretax
        annual compensation, as defined in the Plan, and up to an additional 8%
        on an after-tax basis. During the plan year, contributions were limited
        to a pre-tax maximum of $8,000 per year. The Bank is required to make a
        matching contribution of twenty-five cents for every dollar on the first
        4% of the compensation that a participant contributes to the Plan on a
        pre-tax basis. In addition, the Bank may voluntarily make additional
        discretionary contributions to the Plan at the end of the year to be
        distributed among the participants' accounts as established in the
        Plan's document. Investment of participants' and employer's
        contributions are directed by participants into various investment
        options, which include several mutual funds and common stock of First
        BanCorp., the Bank's parent company. Contributions are subject to
        certain limitations.

        PARTICIPANT ACCOUNTS

        Each participant's account is credited with the participant's
        contributions and allocations of (a) the Bank's contributions and (b)
        Plan earnings, and charged with an allocation of investment management
        expenses. Allocations are based on participant earnings or account
        balances, as defined. The benefit to which a participant is entitled is
        the benefit that can be provided from the participant's vested account.

        VESTING

        Participants are immediately vested in their contributions and
        employer's matching contribution plus actual earnings thereon.

FIRSTBANK 401(K) RETIREMENT PLAN FOR RESIDENTS OF PUERTO RICO
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2003 AND 2002
--------------------------------------------------------------------------------

        Effective January 1, 2002, the Plan was amended to adopt a graded
        vesting schedule for the Bank's additional discretionary contribution as
        follows:




                Years of                              Vested
                 Service                            Percentage
                                                 
                Less than 2                              0%
                 2                                      20%
                 3                                      40%
                 4                                      60%
                5 or more                              100%


        LOANS TO PARTICIPANTS

        Under the terms of the Plan, participants are allowed to borrow from
        their accounts up to 50% of their vested account balance or $50,000
        whichever is less. Loan transactions are treated as a transfer to
        (from) the investment funds from (to) the Participants Loan Fund. Loans
        are secured by the balance in the participants' accounts and bear
        interest at the rate determined by the Plan administrator at the time of
        the loan. The interest rate of these loans range from 6% to 9%.
        Principal and interest is paid ratably through biweekly payroll
        deductions.

        PAYMENT OF BENEFITS

        Plan participants are permitted to make withdrawals from the Plan,
        subject to provisions in the Plan agreement. If a participant suffers
        financial hardship, as defined in the Plan agreement, the participant
        may request a withdrawal from his or her contributions. In the case of
        participant termination because of death, the entire vested amount is
        paid to the person or persons legally entitled thereto.

        Benefits are paid in a lump-sum cash payment. If the value of the vested
        account is more than $5,000, the participant may elect to defer any
        benefit payable under the Plan until a specified future date. If benefit
        payments are to be deferred, the Plan will earmark the balance as part
        of its assets in a special account or a deposit certificate with the
        funds of the former member. Interest earned on such special account is
        paid to the participant. Such special accounts or certificates do not
        participate in the allocation of the Bank's contributions or earnings of
        the Plan's investments. There were no deferred vested benefits at
        December 31, 2003.

        PLAN EXPENSES AND ADMINISTRATION

        Bank and participant contributions are held by AST Trust Company as
        custodian and managed by Milliman USA, Inc. as plan recordkeeper, both
        appointed by the Board of Directors of the Bank. The custodian invests
        cash received, interest and dividend income and makes distributions to
        participants.

        Administrative fees are paid by the Bank.

        FORFEITURES

        Forfeited balances of terminated participants' nonvested accounts are
        used to reduce future Bank contributions or used to cover administrative
        expenses of the Plan for the following year.

2.      SUMMARY OF ACCOUNTING POLICIES

        BASIS OF FINANCIAL STATEMENTS

        The Plan's policy is to prepare its financial statements using the
        accrual basis of accounting.

        USE OF ESTIMATES

        The preparation of financial statements in conformity with accounting
        principles generally accepted in the United States of America requires
        management to make estimates and assumptions that affect the reported
        amounts of assets and liabilities and disclosure of contingent assets
        and liabilities at the date of the financial statements and the reported
        amounts of revenues and expenses during the reporting period. Actual
        results could differ from those estimates.

        CONTRIBUTIONS

        Employee contributions are recorded in the period in which the Bank
        makes payroll deductions from the participants' compensation. Matching
        employer's contributions are recorded in the same period.

        INVESTMENTS VALUATION AND INCOME RECOGNITION

        The Plan's investments in mutual funds and common stock of First
        BanCorp. are stated at fair value. Shares of registered investment
        companies are valued at quoted market prices which represent the net
        asset value of shares held by the Plan at the reporting date. First
        BanCorp.'s common stock is valued at its quoted market price. The Plan
        presents in the statements of changes in assets available for benefits
        the net appreciation (depreciation) in the fair value of its investments
        which consists of the realized gains or losses and the unrealized
        appreciation (depreciation) on them.

        Purchases and sales of securities are recorded on a trade-date basis.
        Interest income is recorded on the accrual basis and dividends are
        recorded on the ex-dividend date.

        PARTICIPANT LOANS

        Participant loans receivable are valued at the amounts receivable from
        participants.

        PAYMENT OF BENEFITS

        Benefits are recorded when paid.

        *Investment exceeds five percent of net assets available for benefits.

        During 2003, the Plan's investments (including gains and losses on
        investments bought and sold) appreciated (depreciated) in values as
        follows:

                                                                 $ 2,374,350

4.      TAX STATUS

        The Puerto Rico Department of Treasury has determined and informed the
        Bank under letter dated April 5, 1993 that the Plan is designed in
        accordance with the applicable sections of the Internal Revenue Code of
        the Commonwealth of Puerto Rico and, therefore, exempt from income
        taxes. The Plan and the income tax law have been amended since receiving
        the determination letter. However, the Plan Administrator believes that
        the Plan is designed and is currently being operated in compliance with
        the applicable requirements of the income tax law.


5.      PLAN TERMINATION

        Although it has not expressed any intent to do so, the Bank has the
        right to discontinue its contributions at any time and to terminate the
        Plan subject to the provisions of ERISA. In the event of Plan
        termination, participants will become 100 percent vested in their
        accounts and such termination shall not reduce the interest of any
        participating employee or their beneficiaries accrued under the Plan up
        to the date of such termination.

6.      FORFEITED AMOUNT

        Forfeited nonvested accounts amounted to $11,603 at December 31, 2003
        (2002 - $4,393). These accounts are transferred by the Plan
        administrator to an unallocated account to be used to cover
        administrative expenses of the Plan for the following year or reduce the
        Bank's future contributions. In 2002, $12,888 from forfeited nonvested
        accounts were used to cover administrative expenses. No forfeitures were
        used to reduce Bank's contributions or administrative expenses in 2003.

7.      RISKS AND UNCERTAINTIES

        The Plan's investments are exposed to various risks, such as interest
        rate, market and credit risks. Due to the level of risk associated with
        certain investments and the level of uncertainty related to changes in
        the values of investments, it is at least reasonably possible that
        changes in these factors in the near term would materially affect the
        amounts reported in the statement of assets available for benefits and
        the statement of changes in assets available for benefits.

8.      ADDITIONAL CONTRIBUTIONS

        The Board of Directors of the Bank approved in 2004 an additional
        contribution of approximately $481,200 based on the Bank's 2003 results
        and has been recorded as employer contribution receivable in the
        statement of net assets available for benefits. In addition, as part of
        the Plan's compliance with its non-discrimination test the Bank agreed
        to contribute approximately $107,600 to non-highly compensated
        participants to satisfy contribution requirements. Such additional
        contribution has been also recorded as employer contribution receivable
        in the statement of net assets for benefits.
