                          INDEPENDENT AUDITORS' REPORT



Plan Administrator
Kirby 401(k) Plan:



We have audited the accompanying statements of net assets available for
benefits (modified cash basis) of the Kirby 401(k) Plan (the Plan) as of
December 31, 2000 and 1999, and the related statements of changes in net assets
available for benefits (modified cash basis) for the years ended December 31,
2000 and 1999. 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.

As described in note 2, these financial statements and supplemental schedule
were prepared on a modified cash basis of accounting, which is a comprehensive
basis of accounting other than generally accepted accounting principles.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan as of
December 31, 2000 and 1999, and the changes in net assets available for
benefits for the years ended December 31, 2000 and 1999 on the basis of
accounting described in note 2.

Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of assets held
for investment purposes 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, as amended. The supplemental 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.

                             (Modified Cash Basis)

                           December 31, 2000 and 1999

(1)    DESCRIPTION OF THE PLAN
       (a)    GENERAL
              The Kirby 401(k) Plan (the Plan) is a defined contribution 401(k)
              plan for the benefit of employees of Kirby Corporation (the
              Company), and certain subsidiaries. Each employee is eligible to
              join the Plan as of the first pay period beginning in any quarter
              following completion of one year of service and the attainment of
              age 18. Employees covered by collective bargaining agreements,
              the terms of which do not provide for participation in the Plan,
              are not eligible. The Plan is subject to the provisions of the
              Employee Retirement Income Security Act of 1974 (ERISA). Further
              information relating to the Plan's provisions is available in the
              Summary Plan Description provided to all eligible employees.

       (b)    PLAN MERGER
              The Hollywood Marine, Inc. (HMI) 401(k) Plan (HMI Plan) was
              merged into the Plan and all HMI balances were transferred to the
              Plan effective December 31, 1999. Commencing January 1, 2000,
              former HMI Plan participants are subject to the same plan
              provisions as the Kirby 401(k) Plan participants.

       (c)    PLAN AMENDMENTS
              In December 1999, the Plan was amended to include HMI employees
              as the HMI Plan was merged into the Plan effective December 31,
              1999.

              Effective December 31, 1999, in connection with the merger of the
              HMI Plan into the Plan, the Plan added the Janus Growth and
              Income Fund, the Vanguard 500 Index Trust, and the Dreyfus
              Emerging Leaders Fund Options.

       (d)    CONTRIBUTIONS
              The Plan provides for basic employee pretax contributions to the
              Plan of 3% of covered compensation as defined, and for additional
              employee pretax contributions to the Plan of up to 14% of covered
              compensation subject to the provisions of the Internal Revenue
              Code. The Company contributes matching employer contributions
              equal to 100% of basic employee pretax contributions. The Company
              does not match the additional employee pretax contributions.

       (e)    BENEFITS PAYMENTS
              Benefits payments are made in a lump-sum distribution to the
              participant upon termination of employment (or to the beneficiary
              in the event of death). However, a participant may request a loan
              for up to 50% of the participant's vested interest up to a
              maximum of $50,000. Loans are typically repaid over a five-year
              period and have interest rates ranging from 7% to 10.5%. Loans
              outstanding upon termination of a participant are considered
              deemed distributions if not repaid and are deducted from the
              participant's account balance prior to distribution. These
              amounts are taxed to the participant in the year of the
              participant's termination.

                                       4                         (Continued)

                         Notes to Financial Statements
                             (Modified Cash Basis)

                           December 31, 2000 and 1999


       (f)    VESTING
              A participant in the Kirby 401(k) Plan, excluding former HMI Plan
              participants, has an immediate and fully vested nonforfeitable
              interest in the portion of the account relating to both
              participant and employer contributions and may, upon resignation
              from or discharge by the employer, withdraw their entire account
              balance.

              Employer contributions made in the prior HMI Plan are subject to
              a five-year vesting schedule based on the participant's HMI
              Service date. Forfeitures of non-vested participants are credited
              to the accounts of former HMI Plan participants based on a
              formula that considers the total compensation, as defined, of all
              former HMI Plan participants for that plan year.

              Commencing January 1, 2000, employer contributions to former HMI
              Plan participants are subject to the same vesting as Kirby
              participants.

       (g)    PLAN ADMINISTRATION
              The general administration of the Plan is vested in the Vice
              President of Human Resources of the Company (the Plan
              Administrator). The Plan Administrator has broad powers regarding
              the operation and administration of the Plan and receives no
              compensation for service to the Plan. All administrative
              expenses, unless paid by the Company at its discretion, are paid
              by the Plan.

       (h)    PLAN TERMINATION
              Although it has not expressed any intent to do so, the Company
              has the right under the Plan to terminate the Plan subject to the
              provisions of ERISA. In the event of termination, the amounts
              credited to the accounts of participants shall vest immediately
              and will be distributed to the participants after payment of
              expenses for distribution and liquidation.

       (i)    RECLASSIFICATIONS
              Certain reclassifications have been made to reflect current
              presentation of financial information.

       (j)    USE OF ESTIMATES
              The preparation of financial statements requires Plan management
              to make estimates and assumptions that affect the reported
              amounts of net assets and disclosure of contingent assets and
              liabilities at the date of the financial statements and the
              reported amounts of additions and deductions to net assets during
              the reporting period. Actual results could differ from those
              estimates. However, in the opinion of Plan management, such
              differences would be immaterial.

       (k)    ACCOUNTING PRONOUNCEMENT
              In September 1999, the American Institute of Certified Public
              Accountants issued Statement of Position 99-3, Accounting for and
              Reporting of Certain Defined Contribution Plan Investments and
              Other Disclosure Matters (SOP 99-3). SOP 99-3 simplifies the
              disclosure requirements for certain investments and is effective
              for plan years ending after December 15, 1999. The Plan adopted
              SOP 99-3 during the Plan year ending December 31, 1999.
              Accordingly, information previously required to be disclosed by
              fund is not presented in the Plan's 1999 financial statements.

(2)    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

       (a)    BASIS OF PRESENTATION
              The accompanying financial statements have been prepared on the
              modified cash basis, which is a comprehensive basis of accounting
              other than generally accepted accounting principles, and is an
              acceptable method of reporting for the Department of Labor and
              ERISA. The modified cash basis of accounting utilizes the cash
              basis of accounting while adjusting debt and equity securities to
              their corresponding market value for financial reporting
              purposes.

       (b)    INVESTMENT VALUATION
              Investments in the common trust fund, mutual funds and Kirby
              Corporation common stock are stated at fair value based on quoted
              market prices. Purchases and sales of investments are recorded on
              a trade date basis. Net realized gains and losses on disposition
              of investments are reported on the revalued cost method. Revalued
              cost is the fair value of the assets at the beginning of the plan
              year or historical cost if the investment was acquired during the
              year. Any unrealized appreciation or depreciation is recognized
              currently in the statement of changes in net assets available for
              benefits. Participant loans are stated at cost which approximates
              their fair value.

(3)    INVESTMENTS

       Each participant has the right to direct his contributions and the
       Company's matching contributions between the investment funds offered by
       the Plan. Descriptions of the Plan's investment fund options are
       included in the summary plan description provided to all eligible
       employees.

       During 2000, the Plan's investments (including realized gains and losses

       investments held during the year) depreciated in value by $3,449,191 as
       follows:

                                       =================

(4)    RELATED PARTY TRANSACTIONS

       Certain plan investment options include shares of Kirby Corporation
       common stock and mutual funds managed by Chase Bank of Texas. Kirby is
       the plan sponsor and Chase Bank of Texas is the recordkeeper and trustee
       as defined by the Plan, and therefore, these transactions qualify as
       party-in-interest transactions.

       The Plan has participant loans outstanding which are secured solely by a
       portion of the participant's vested account balance, in accordance with
       the plan document.

(5)    FEDERAL INCOME TAXES

       The Plan obtained its latest determination letter on December 30, 1996
       in which the Internal Revenue Service stated that the Plan, as then
       designed, was in compliance with the applicable requirements of the
       Internal Revenue Code. The Plan has been amended since receiving this
       determination letter. However, the Plan Administrator believes the Plan
       is currently designed and operated in compliance with the applicable
       requirements of the Code. Therefore, the Plan Administrator believes the
       Plan was qualified and the related trust was tax-exempt as of December
       31, 2000. The Company intends to continue to administer the Plan, and
       its related trust, so it will qualify for tax-exempt status.

                           December 31, 2000 and 1999

       A participant is not taxed on employer contributions when made; instead,
       taxation is deferred until the amount credited to the participant's
       account is distributed or made available to him or, in the event of the
       participant's death, to a beneficiary or an estate. Amounts distributed
       or made available to employees or their beneficiaries, in excess of
       their contributions, are taxable according to the provisions of the
       Internal Revenue Code.
