                        REPORT OF INDEPENDENT ACCOUNTANTS

To the Plan Administrator
Ecolab Savings Plan

     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 the Ecolab Savings Plan (the "Plan") as of December 31, 2000 and
1999, and the changes in net assets available for benefits for the year ended
December 31, 2000, in conformity with accounting principles generally accepted
in the United States of America. These financial statements are the
responsibility of the Plan Administrator; 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 auditing standards generally
accepted in the United States of America, which 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 the
Plan Administrator, 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 schedules referred
to in the accompanying index on page 1 are presented for the purpose of
additional analysis and are not a required part of the basic financial
statements but are 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. These supplemental schedules are the
responsibility of the Plan Administrator. The supplemental schedules have been
subjected to the auditing procedures applied in the audits of the basic
financial statements and, in our opinion, are fairly stated in all material
respects in relation to the basic financial statements taken as a whole.

                          NOTES TO FINANCIAL STATEMENTS

1.     DESCRIPTION OF PLAN:

       The following brief description of the Ecolab Savings Plan (the "Plan")
       is provided for general information purposes only. Participants should
       refer to the Plan document for complete information regarding the Plan's
       definitions, benefits, eligibility and other matters.

       GENERAL AND ELIGIBILITY:

       The Plan is a contributory qualified defined contribution plan available
       to employees of Ecolab Inc. (the "Company") and certain of its
       subsidiaries. Employees regularly scheduled to work at least 20 hours per
       week may participate immediately in the Plan provided they are not
       subject to a collective bargaining agreement which does not provide for
       their inclusion. Part-time employees working less than 20 hours a week
       must have been employed for a twelve consecutive month period during
       which they have worked at least 1,000 hours to be eligible to
       participate. Employee participation in the Plan is voluntary.

       The Plan is subject to the provisions of the Employee Retirement Income
       Security Act of 1974, as amended ("ERISA") and the Internal Revenue Code
       of 1986, as amended (the "Code").

       GCS Service Inc. (an entity recently acquired by the Company) employees
       became eligible to participate in the Plan effective July 31, 1999.

       CONTRIBUTIONS:

       Contributions are made to the Plan as "before-tax savings contributions,"
       "after-tax savings contributions," "employer matching contributions" or
       "employer profit sharing contributions."

       Before-tax savings contributions are contributions made by the Company on
       behalf of participants who have agreed to have their taxable compensation
       reduced. Participants may reduce their compensation up to 10% (subject to
       a statutory annual maximum of $10,500 for 2000) for the purpose of making
       before-tax savings contributions to the Plan.

                                   (Continued)

                               ECOLAB SAVINGS PLAN
                   NOTES TO FINANCIAL STATEMENTS, (Continued)

1.     DESCRIPTION OF PLAN, (Continued):

       After-tax savings contributions are contributions made by the Company on
       behalf of participants through after-tax payroll deductions. The total of
       before-tax and after-tax savings contributions made on behalf of a
       participant cannot exceed 16% of a participant's compensation.

       Employer matching contributions are made by the Company in an amount
       equal to 50% of the total before-tax and after-tax savings contributions
       for a payroll period up to a maximum 6% of a participant's eligible
       compensation for that period, as defined. Employer matching contributions
       are invested entirely in the Ecolab Stock Fund.

       Employer profit sharing contributions are discretionary and are
       determined annually by the Company's Board of Directors. If made, profit
       sharing contributions are divided among participants who are not eligible
       for a management incentive or equivalent bonus. Discretionary employer
       profit sharing contributions are also invested entirely in the Ecolab
       Stock Fund.

       The levels of contributions made by or on behalf of participants who are
       "highly compensated", as defined in the Code, are subject to limitations
       under the Code based on the level of contributions made by employees who
       are not considered highly compensated.

       VESTING:

       Participant interests in before-tax savings contributions, after-tax
       savings contributions, discretionary employer profit sharing
       contributions and investment income thereon are always 100% vested.
       Participants become vested in the employer matching contributions and
       investment income thereon at a rate of 25% each year, after two years of
       continuous service, until fully vested after five years of continuous
       service. Participants also become fully vested in employer matching
       contributions and investment income thereon in the event of death or
       total disability while employed by the Company or upon retirement at, or
       after, age 65.

       PLAN BENEFITS:

       Benefits to participants are limited to the amount vested in each
       participant's account. Upon retirement, death, disability or separation
       from service, a distribution may be made to the participant or
       beneficiary equal to the vested portion of the participant's account. An
       employee distribution or withdrawal from the Plan generally is subject to
       federal income tax and may be subject to a 10% penalty. Forfeitures of
       non-vested employer matching contributions and related investment income
       are used to reduce future employer contributions.

1.     DESCRIPTION OF PLAN, (Continued):

       PARTICIPANT LOANS:

       Active employee participants (and beneficiaries who are parties in
       interest as defined by ERISA) are permitted to borrow from their
       accounts. The total amount of a participant's loan may not exceed the
       lesser of (a) $50,000 minus the participant's highest outstanding loan
       balance for the previous twelve-month period, or (b) 50% of the
       participant's vested interest in his or her account. When a loan is
       granted, the appropriate account balances are reduced and a separate loan
       account is created. Loan payments, together with interest at a market
       rate determined by the Plan Administrator, are repaid generally over 5 or
       10 years. Participant loans at December 31, 2000 had interest rates
       ranging from 6.0% to 9.5%. No more than two loans can be outstanding at
       any time. Participant loans are collateralized by a borrower's vested
       account balance and are repaid through payroll deductions.

       PARTICIPANT ACCOUNTS AND ALLOCATION:

       Fidelity Management Trust Company ("Fidelity"), a division of Fidelity
       Investments Institutional Services Company, Inc., provides investment
       management, recordkeeping and trustee services for the Plan directly or
       indirectly through one or more of its subsidiaries. The trust agreement
       authorizes services to be performed by the trustee, its agents or
       affiliates.

       Each participant's account is credited with the participant's
       contributions, the employer matching contributions, any employer profit
       sharing contributions and investment income thereon.

       Except for employer matching and profit sharing contributions and
       investment income thereon which are invested entirely in the Ecolab Stock
       Fund, participants are allowed to allocate their entire account balance
       and their before-tax and after-tax savings contributions in any
       combination of investment options (19 at December 31, 2000). Participants
       can transfer their account balances among the investment options and/or
       change the investment of their future contributions, and earnings thereon
       daily. These transfers and changes must be made in whole dollar amounts
       of at least $250 and/or in whole percent increments.

1.     DESCRIPTION OF PLAN, (Continued):

       All contributions made under the Plan are paid to and invested by
       Fidelity in one or more of the available investment options as directed
       by the participants. Seventeen of the 19 investment options existing at
       December 31, 2000 are mutual funds. The remaining two investment options
       include a fund invested primarily in investment contracts (the Managed
       Income Fund) and a non-diversified fund invested primarily in Ecolab Inc.
       common stock, held by Fidelity Management Trust Company (the Ecolab Stock
       Fund).

       PLAN TERMINATION:

       Although it has not expressed any intent to do so, the Company has the
       right under the Plan 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 would become 100% vested in their
       accounts.

                   NOTES TO FINANCIAL STATEMENTS, (Continued)

2.     SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

       The financial statements are prepared in conformity with generally
       accepted accounting principles and use the following significant
       accounting policies.

       VALUATION OF INVESTMENTS:

       Investments in the Managed Income Fund are recorded at the underlying net
       asset value per unit as determined by the Plan's trustee, which
       approximates fair value. Investments in the Ecolab Stock Fund are
       recorded at the underlying net asset value per unit as determined by the
       Plan's trustee, which approximates fair value based on the quoted market
       price of the Company's common stock. Mutual funds are recorded at the
       underlying net asset value per unit, which approximates fair value based
       on the publicly quoted market price of these funds. The Plan determines
       the cost of investments sold by the average cost method. Participant
       loans receivable are recorded at the principal value of outstanding
       loans, plus accrued interest, which approximates fair value.

       INTEREST AND DIVIDENDS:

       Interest income is recorded as earned on an accrual basis and dividend
       income is recorded on the ex-dividend date.

       NET APPRECIATION (DEPRECIATION) IN THE FAIR VALUE OF MUTUAL FUNDS:

       The Plan presents in the Statements of Changes in Net Assets Available
       for Benefits, the net appreciation (depreciation) in the fair value of
       mutual funds, which consists of the realized gains or losses and the
       unrealized appreciation (depreciation) on those mutual funds.

       INCREASE IN PLAN'S INTEREST IN OTHER FUNDS:

       The Plan presents in the Statement of Changes in Net Assets Available for
       Benefits, the increase in Plan's interest in other funds, which consists
       of the change in the fair value of investments which consists of the
       realized gains or losses and the unrealized appreciation (depreciation)
       on those investments.

       CONTRIBUTIONS:

       Participant before-tax and after-tax savings contributions are recorded
       in the period the employer makes the payroll deductions. Employer
       matching contributions are recorded based on participant contributions.
       No discretionary employer profit sharing contributions were made for the
       2000 Plan year.

                   NOTES TO FINANCIAL STATEMENTS, (Continued)

2.     SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, (Continued):

       USE OF ESTIMATES:

       The preparation of the Plan's financial statements in conformity with
       accounting principles generally accepted in the United States of America
       requires the Plan Administrator to make significant estimates and
       assumptions that affect the reported amounts of Net Assets Available for
       Benefits at the date of the financial statements and the changes in Net
       Assets Available for Benefits during the reporting period and, when
       applicable, disclosures of contingent assets and liabilities at the date
       of the financial statements. Actual results could differ from those
       estimates.

       RISKS AND UNCERTAINTIES:

       The Plan provides for various investment options in various combinations
       of investment funds. Investment funds are exposed to various risks, such
       as interest rate, market and credit risks. Due to the level of risk
       associated with certain investment securities, it is at least reasonably
       possible that changes in the values of investment securities will occur
       in the near term and that such changes could materially affect
       participants' account balances and the amounts reported in the Statement
       of Net Assets Available for Benefits in future periods.

       CONCENTRATION OF MARKET RISK:

       As of December 31, 2000 and 1999, approximately 52% of the Plan's net
       assets were invested in the common stock of Ecolab Inc. The underlying
       value of the Ecolab Stock Fund is entirely dependent on the performance
       of Ecolab Inc. and the market's evaluation of such performance. It is at
       least reasonably possible that changes in the fair value of Ecolab Inc.
       common stock in the near term could materially affect participants'
       account balances and the amounts reported in the Statement of Net Assets
       Available for Benefits and the Statement of Changes in Net Assets
       Available for Benefits.

       DISTRIBUTIONS TO PARTICIPANTS:

       Distributions to participants are recorded when the distribution is made.

       PLAN EXPENSES:

       The Company pays a portion of the administrative expenses of the Plan and
       a portion is paid by plan participants within plan. Certain asset
       management and administrative fees of the Plan are charged against the
       Plan's investment income.

5.      TAX STATUS:

        The Plan constitutes a qualified trust under Section 401(a) of the Code
        and therefore is exempt from federal income taxes under provisions of
        Section 501(a). The Plan also complies with the provisions of Section
        401(k) of the Code. A tax qualification letter, dated October 26, 1994,
        was received from the Internal Revenue Service. The letter stated that
        the Plan, as then designed, was in compliance with the applicable
        requirements of the Code. The Plan has been amended since receiving the
        determination letter. However, the Plan Administrator believes the Plan
        is currently designed and being operated in compliance with the
        applicable requirements of the Code and therefore believes the Plan is
        qualified and tax-exempt, as described above. Therefore, no provision
        for income taxes has been included in the Plan's financial statements.

6.      RELATED PARTY AND PARTY-IN-INTEREST TRANSACTIONS:

        The trustee is authorized under contract provisions, or by ERISA
        regulations providing an administrative or statutory exemption, to
        invest in funds under its control and in securities of the Company.

        Participant contributions are invested in one or more of the investment
        fund options offered under the Plan, including the Ecolab Stock Fund. In
        addition, employer matching and profit sharing contributions are
        invested in the Ecolab Stock Fund, consisting of primarily Ecolab Inc.
        common stock and also short-term investment funds under the trustee's
        control. In 2000, the amount of such purchases and sales of funds
        managed by the trustee and the fund consisting of Company stock were as
        follows (dollars in thousands):
