                          INDEPENDENT AUDITORS' REPORT

Director's Compensation and Stock Option Committee
Bank United 401(k) Retirement Savings Plan:

We have audited the accompanying statements of net assets available for plan
benefits of Bank United 401(k) Retirement Savings Plan as of December 31, 2000
and 1999, and the related statement of changes in net assets available for plan
benefits for the year ended December 31, 2000. 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 of America. 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 plan benefits as of
December 31, 2000 and 1999 and the changes in net assets available for plan
benefits for the year ended December 31, 2000 in conformity with accounting
principles generally accepted in the United States of America.

Our audits were performed for the purpose of forming an opinion on the basic
financial statements taken as a whole. The Schedule H, Line 4i-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 schedule is the responsibility of the Plan's
management. The schedule has been subjected to the auditing procedures applied
in the audits 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.

                           DECEMBER 31, 2000 AND 1999

(1) DESCRIPTION OF PLAN

    (a) ORGANIZATION OF PLAN

       The Bank United 401(k) Retirement Savings Plan (the Plan) was established
       effective January 1, 1989 for the benefit of its eligible employees. The
       Plan's sponsor is Bank United and its subsidiaries (the Bank). The Plan
       is a defined contribution plan created as authorized by Section 401(k) of
       the Internal Revenue Code (the Code). Fidelity Management Trust Company
       is trustee and recordkeeper of the Plan. The specific provisions of the
       Plan, including eligibility, contributions, priorities upon termination
       and benefit information, are contained in the Plan document which governs
       the legal operations of the Plan. Participants should refer to the Plan
       document for more complete information.

       Effective January 1, 2000, the Plan was amended to change eligibility,
       employer contributions, and the vesting schedule for participants, as
       indicated in sections 1(b)--1(e).

    (b) ELIGIBILITY AND PARTICIPATION

       Participation in the Plan is voluntary. Any employee who has completed
       one month of service with the Bank or a participating subsidiary (the
       Employers) and has attained the age of 21 is eligible to become a
       participant of the Plan.

    (c) CONTRIBUTIONS

       The Plan is a defined contribution plan through which participants may
       voluntarily agree to contribute from 1 to 15 percent of their
       compensation (as defined by the Plan document), subject to certain
       limitations under the Internal Revenue Code. The employer makes matching
       contributions to the Plan of 100% of the first 4% of a participant's
       annual compensation.

    (d) PARTICIPANT ACCOUNTS

       Each participant's account is credited with the participant's
       contribution and allocations of (a) the Bank's contribution and (b) Plan
       earnings or losses, and charged with an allocation of administrative
       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.

    (e) VESTING

       Participants are 100% vested with respect to their rollovers and
       contributions plus actual earnings thereon. Participants become fully
       vested in the Bank's matching contribution portion of their accounts plus
       actual earnings after one year of active service. Participants are
       automatically 100% vested upon retirement, death or disability (as
       defined in the Plan).

    (f) INVESTMENTS

       Contributions and any investment income thereon are invested at the
       direction of each participant in one or a combination of the options set
       forth below:

           - BANK UNITED CORP. STOCK FUND--The Bank United Corp. Stock Fund is a
             unitized stock fund allowing participants to invest in the Bank's
             stock while allowing for day

                         NOTES TO FINANCIAL STATEMENTS

                           DECEMBER 31, 2000 AND 1999

(1) DESCRIPTION OF PLAN (CONTINUED)
             trading similar to a mutual fund. The fund is comprised of Bank
             United Corp. Stock and a short-term cash component. The short-term
             cash component provides liquidity for daily trading. This fund
             differs from a mutual fund since a mutual fund is a registered
             security and a unitized fund is not a registered security.

           - FIDELITY MAGELLAN FUND--The Magellan Fund invests in common stock
             and securities convertible to common stock issued by companies
             operating in the United States and/or abroad as well as foreign
             companies.

           - FIDELITY INTERMEDIATE BOND FUND--The Intermediate Bond Fund invests
             in corporate debt obligations that are rated Aaa, Aa or A by
             Moody's Investor Service, Inc. or AAA, AA or A by Standard & Poor's
             Corporation. The fund also invests in obligations issued or
             guaranteed by the U.S. government or any of it agencies or
             instrumentalities and in obligations of U.S. banks, including
             certificates of deposit and bankers' acceptances. The issues have
             limited or long-term maturities.

           - FIDELITY GROWTH & INCOME FUND--The Growth & Income Fund invests in
             any combination of common stock, securities convertible to common
             stock, preferred stock and fixed-income securities. Securities may
             be of foreign or domestic issuers. It is expected that the primary
             fixed-income investments will be in corporate bonds.

           - FIDELITY FUND--The Fidelity Fund invests in the common stock and
             securities convertible into common stock of well-established
             companies. The fund may hold the stock and fixed-income securities
             of smaller corporations.

           - FIDELITY RETIREMENT MONEY MARKET FUND--The Retirement Money Market
             Fund invests funds in high-quality, U.S. dollar-denominated money
             market instruments of U.S. and foreign issuers. Investments include
             short-term corporate obligations, U.S. government obligations and
             certificates of deposit.

           - FIDELITY ASSET MANAGER FUND--The Asset Manager Fund invests funds
             in stocks, bonds and short-term instruments, both domestic and
             foreign. Its investment strategy is to seek high total return with
             reduced risk over the long term.

           - FIDELITY ASSET MANAGER: GROWTH FUND--The Asset Manager: Growth Fund
             invests funds in stocks, bonds and short-term instruments, both
             domestic and foreign. Its investment strategy is to seek to
             maximize total return over the long term.

           - FIDELITY ASSET MANAGER: INCOME FUND--The Asset Manager: Income Fund
             invests funds in stocks, bonds and short-term instruments, both
             domestic and foreign. Its investment strategy is to seek high
             current income while considering the potential for capital
             appreciation.

           - FIDELITY OVERSEAS FUND--The Overseas Fund invests in stocks and
             bonds of companies whose principal business activities are outside
             the United States. Its investment strategy seeks long-term growth
             of capital by investing at least 65% of the fund's total assets in
             securities of issuers from at least three different countries
             outside of North America.

    (g) PARTICIPANT LOANS

       Participants may borrow from their fund accounts a minimum of $1,000 and
       up to a maximum equal to the lesser of $50,000 or 50 percent of their
       vested account balance. Loan terms range from one to five years or up to
       15 years for the purchase of a primary residence. The loans are secured
       by the balance in the participant's account and bear an interest rate
       equal to the prime interest rate on the first business day of the month.
       The interest rate is updated to the trustee on a monthly basis by the
       plan administrator. Interest rates range from 7.75 to 10 percent.
       Principal and interest are paid ratably through payroll deductions.

    (h) PAYMENT OF BENEFITS

       Benefits will be distributed to participants only upon retirement, death,
       total and permanent disability, severance of employment with the
       Employers or in the event of financial hardship (as defined in the Plan).
       A participant may elect to receive payment in either a lump sum amount or
       series of payments equal to the value of the participant's vested
       interest in his or her account.

    (i) EXPENSES

       Investment management fees are deducted from fund earnings while other
       fees and administrative expenses are paid by the Employers.

    (j) FORFEITURES

       During 2000, forfeitures totaling $75,201 were deposited into the Plan's
       Forfeiture Account, which can be used to reduce future employer
       contributions.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    (a) BASIS OF ACCOUNTING

       The financial statements of the Plan are prepared under the accrual
       method of accounting in accordance with accounting principles generally
       accepted in the United States of America. These principles require
       management to make estimates and assumptions that affect the reported
       amounts of assets, liabilities, and changes therein, and disclosure of
       contingent assets and liabilities; accordingly, actual results could
       differ from those estimates.

    (b) NEW ACCOUNTING PRONOUNCEMENTS

       In June 1998, the Financial Accounting Standards Board issued SFAS
       No. 133, ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES
       (SFAS No. 133). SFAS No. 133 requires that an entity recognize all
       derivatives and measure those instruments at fair value.

       SFAS No. 133 is effective for fiscal years beginning after June 15, 2000.
       Pursuant to SFAS No. 137, the Plan is required to adopt SFAS No. 133
       effective January 1, 2001. Management has not yet determined the impact
       of SFAS No. 133 on the Plan's financial statements.

    (c) INVESTMENT VALUATION AND INCOME RECOGNITION

       Investment securities are carried at fair value as determined by the
       Plan's trustee, based primarily on quoted market values of the underlying
       stocks or securities. Purchases and sales of investment securities are
       recorded as of the trade dates. Gains and losses on sales of these
       securities are computed on an average cost basis. Interest income is
       recorded on the accrual basis, while dividends are recorded on the
       ex-dividend date. Participant loans are valued at cost, which
       approximates fair value.

    (d) FINANCIAL INSTRUMENTS

       The carrying value of financial instruments such as receivables and
       payables approximate their fair value.

(3) INVESTMENTS

    In September 1999, the American Institute of Certified Public Accountants
    issued Statement of Position 99-3, ACCOUNTING FOR AND REPORTING ON CERTAIN
    DEFINED CONTRIBUTION PLAN INVESTMENTS AND OTHER DISCLOSURE MATTERS (SOP
    99-3). SOP 99-3 simplifies the disclosure for certain investments and is
    effective for Plan years ending after September 15, 1999. The Plan adopted
    SOP 99-3 during the Plan year ended December 31, 1999. Accordingly,
    information previously required to be disclosed about participant-directed
    fund investment programs is not presented in the Plans financial statements.

(4) PARTY-IN-INTEREST TRANSACTIONS

    Certain plan investments are shares of mutual funds managed by Fidelity
    Management Trust Company (Fidelity). Fidelity is the trustee as defined by
    the Plan and, therefore, these transactions qualify as party-in-interest.

(5) TERMINATION OF THE PLAN

    Although it has not expressed any intent to do so, the Bank may discontinue
    contributions, amend, or terminate the Plan at any time. If the Plan is
    terminated, participants will become fully vested in employer contributions
    and net earnings or loss thereon.

(6) TAX STATUS

    The Internal Revenue Service has determined and informed the Bank by a
    letter dated September 11, 1995, that the Plan was in compliance with
    applicable sections of the Code. The Plan administrator and the Plan's tax
    counsel believe that the Plan is designed and is currently being operated in
    compliance with the applicable requirements of the Code. Accordingly, no
    provision for income taxes has been included in the Plan's financial
    statements.

(7) SUBSEQUENT EVENT

    On February 9, 2001, Bank United merged with and into Washington
    Mutual, Inc. Subsequent to the merger and prior to May 1, 2001, participants
    could continue to participate in the Plan. Subsequent to May 1, 2001,
    contributions to the Plan were frozen and participants will be eligible to
    participate in the Washington Mutual, Inc. Retirement Savings and Investment
    Plan (RSIP). Assets of the Plan will be merged into the RSIP on July 1,
    2001.
