Report of Independent Registered Public Accounting Firm

The Benefits and Finance Administration Committee

Beckman Coulter, Inc. Savings Plan:

We have audited the accompanying statement of net assets available for benefits of the Beckman Coulter, Inc. Savings Plan (the Plan) as of December 31, 2004, and the related statement of changes in net assets available for benefits for the year 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 audit.

We conducted our audit 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. 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 audit provides 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 Plan as of December 31, 2004, and the changes in net assets available for benefits for the year then ended in conformity with U.S. generally accepted accounting principles.

Our audit was performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental Schedule H, Line 4i - Schedule of Assets (Held at End of Year) as of December 31, 2004, 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.

BECKMAN COULTER, INC. SAVINGS PLAN

Notes to Financial Statements

December 31, 2004 and 2003

(1) Description of Plan

The following description of Beckman Coulter, Inc. Savings Plan (the Plan) provides only general information. Participants should refer to the Plan document for a complete description of the Plan’s provisions.

(a) General

Beckman Coulter, Inc. (the Company) established and adopted the Plan effective August 1, 1989.

The Plan is a defined contribution plan covering substantially all Company employees who have completed a three-month period of employment with the Company. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). The Plan is administered by the Benefits and Finance Administration Committee (the Committee), whose members are appointed by the Board of Directors of the Company.

(b) Contributions

Participants may elect to contribute up to 45% of their eligible pay in combination of pretax and after-tax withholdings. Each participant’s pretax contributions in the calendar year may not exceed $13,000 and $12,000 in 2004 and 2003, respectively. Additionally, participants age 50 or greater may contribute up to $3,000 and $2,000 in 2004 and 2003, respectively, as a catchup contribution.

The Company matches 70% of participants’ contributions invested in Beckman Coulter, Inc. common stock and 50% of other contributions, up to 5% of participants’ total compensation. Forfeitures are applied to reduce the Company’s contributions.

Retirement Plus was established in 1996 for the benefit of employees of Coulter Corporation. Employees of the Coulter Corporation as of the acquisition date of October 31, 1997, and hired through April 30, 2000, participate (or are eligible for participation) upon completing one year of service. Annually, the Company makes contributions to participants’ Retirement Plus accounts. These contributions consist of a basic contribution which ranges from 3% to 9% of eligible pay for the year and an excess contribution which ranges from 0% to 4% of eligible pay that is above the Social Security taxable wage base for the year. Both ranges are based on the participant’s age.

Upon commencement of benefit payments, participants are subject to federal income tax on the receipt of participant pretax contributions, Company contributions, and earnings on all contributions.

(c) Investment Options

Participants have a choice of various investment funds for their contributions. Company contributions may be directed to any of these core investment funds. Participants have the right to elect investment options upon enrollment or reenrollment into the Plan. Additionally, participants may elect to change their investment options and to transfer their account balances among the different investment funds on a daily basis.

Income on investment funds is allocated to participants’ accounts based on the participants’ investment fund balance as a percentage of the total investment fund balance.

(d) Participant Loans

Participants may borrow from their fund accounts a minimum of $1,000 up to a maximum equal to the lesser of $50,000 or 50% of their account balance. Repayment is generally required within 5 years or up to 15 years for the purchase of a principal residence. The loans are secured by the balance in the participant’s account and bear interest at prime rate plus 1%, determined at the beginning of each quarter (6.25% at December 31, 2004 for new loans).

(e) Participant Accounts

Each participant’s account is credited with: (a) the participant’s contributions, (b) the Company’s contributions, and (c) Plan earnings. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested balance.

(f) Benefits and Vesting

Participants become entitled to payment of the total vested value of their accounts at the time of termination, retirement, permanent layoff, permanent disability, or death. If total vested value is greater than $5,000, the participants may elect to postpone their distribution until the year following the year they attain age 70-1/2.

Participants’ interests in the Company’s contributions, income, gains, and losses on investments become fully vested immediately upon enrolling in the Plan, except for Retirement Plus contributions, which vest after five years of employment. Participants also become fully vested in Retirement Plus upon reaching normal retirement age, death, or permanent disability. Participants immediately vest in the value of their own contributions.

(g) Forfeitures

All forfeitures of benefits reduce total cash contributions made by the Plan sponsor. Forfeitures are rare as the majority of Plan participants are 100% vested upon enrollment.

(h) Benefits Payable

At December 31, 2004 and 2003, the amounts of benefits payable to participants who have withdrawn from participation in the Plan were $10,804 and $162,842, respectively. Such amounts are not considered liabilities for financial reporting purposes, and accordingly, the balances are not included in the deductions from Plan assets attributed to distribution of benefits for the years ended December 31, 2004 and 2003.

(i) Continuation of the Plan

The Company anticipates and believes the Plan will continue without interruption but reserves the right to discontinue the Plan. If the Plan is terminated by the Company, the accounts of all affected participants become 100% vested and nonforfeitable without regard to the years of service of participants.

(2) Summary of Significant Accounting Policies

(a) Basis of Presentation

The accompanying financial statements have been prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States of America.

(b) Investment Valuation

Investments are stated at fair value except for guaranteed investment contracts, which are stated at contract value (see note 3). The fair value of the common stock is based on quotations obtained from national securities exchanges on the last business day of the Plan year. The fair values of the mutual funds and commingled funds are based on the net asset value reported by the funds. The purchases and sales of securities are recorded as of the date of trade. The average-cost method is used in determining gains and losses on the sales of securities.

(c) Administrative Expenses

Substantially all of the Plan’s administrative expenses are paid by the Company. The Company has elected to pay these administrative expenses on behalf of the Plan but reserves the right to change this election. Such expenses amounted to approximately $35,974 and $29,962 for the years ended December 31, 2004 and 2003, respectively.

(d) Cash and Cash Equivalents

The Plan considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.

(e) Risks, Concentrations, and Uncertainties

The Plan provides for various investment options in any combination of equity, fixed-income, and other investment securities. Investment securities are exposed to various risks, such as interest rate, market, and credit. Due to the level of risk associated with certain investment securities and the level of uncertainty related to changes in the value of investment securities, it is at least reasonably possible that changes in risks in the near term could materially affect participants’ account balances and the amounts reported in the statements of net assets available for benefits and the statements of changes in net assets available for benefits.

The Plan allows participants to invest in the common stock of the plan sponsor, Beckman Coulter, Inc. The Plan's investment in the common stock of the Plan Sponsor was 15.5% and 13.5% of plan assets as of December 31, 2004 and 2003, respectively.

(3) Valuation of Investment Contracts

The Interest Income Fund includes investments in guaranteed investment contracts (GICs) and synthetic GICs. The Plan’s investments in GICs are included in the statements of net assets available for benefits at contract value (which represents contributions made under the contract plus earnings, less withdrawals and administrative expenses) because they are fully benefit responsive. For example, participants may ordinarily direct the withdrawal or transfer of all or a portion of their investment at contract value.

Withdrawals resulting from events initiated by the Company, such as Plan termination, are not typically considered participant-initiated transactions. With such an event, some of the contracts contain contingencies that could lead to withdrawal penalties. However, since no such events are being contemplated at this time or the withdrawals resulting from such an event will be funded outside the contracts’ provisions, these “potential” limitations do not jeopardize the contract value reporting for these investments.

Contract value for the synthetic GICs is determined based on the fair value of the assets underlying the synthetic GICs. The difference between the fair value of the assets underlying the synthetic GICs and the contract value of the GICs is the value of the “wrapper” contract issued by a third party. The fair value for GICs varies based on the type of contract held (e.g., security-backed investments and general account investments). Fair value for security-backed investment contracts was derived from outside sources, based on the type of investment held.

GICs provide a fixed crediting interest rate, and a financially responsible entity guarantees liquidity at contract value prior to maturity for any and all participant-initiated benefit withdrawals, loans, or transfers arising under the terms of the Plan, which allows access for all participants.

Synthetic GICs operate similarly to a separate account guaranteed investment contract, except that the assets are placed in a trust with ownership by the Plan rather than a separate account of the issuer and a financially responsible third party issues a wrapper contract that provides that participants can, and must, execute Plan transactions at contract value.

Inasmuch a trust assets are owned by the Plan, the wrapper contract and the assets in trust are separately valued and disclosed. The wrapper contract is valued at the difference between the fair value of the trust assets and the contract value attributable by the wrapper to such assets. When considered together, the trust assets and the wrapper contract are reported at the wrapper contract value because participants are guaranteed return of principal and accrued interest.

During 2004, the average yield earned on amounts invested in the GICs was 4.59%. As of December 31, 2004 and 2003, the average crediting interest rate on such contracts was 4.70% and 4.61%, respectively. There ware no valuation reserves recorded to adjust contract amounts during the Plan years. Crediting rate resets are applied to specific investment contracts, as determined at the time of purchase. The reset values for security-backed investment rates are a function of contract value, market value, yield, and duration. General account investment rates are based on a predetermined index rate of return, plus a fixed-basis point spread.

The following is a reconciliation between the contract value and the fair value of the synthetic GICs at December 31, 2004 (dollar amounts in thousands):
