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 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 estimate made by management, and evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion. The financial statements of the Plan as of December 31, 2001 and for the year then ended were audited by other independent accountants whose report dated June 27, 2002 expressed an unqualified opinion on those statements. Our audit was conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule 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.

Plan Description The following description of the Thermo Electron Corporation Choice Plan (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 Thermo Electron Corporation Choice Plan (the Plan) is a defined contribution plan. The Plan covers eligible full-time and part-time employees of Thermo Electron Corporation and subsidiaries (the Company) who have completed two months of service. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). Contributions Each year participants may contribute up to 50 percent of pre-tax annual compensation or $11,000, as defined in the Plan. Participants may also contribute amounts representing distributions from other qualified defined benefit or defined contribution plans. Beginning on the first day of the calendar quarter following completion of one year of service, the Company makes non-discretionary matching contributions equal to 200 percent of the first 2 percent and 25 percent of the next 2 percent of base compensation that a participant contributes to the Plan. Participants direct the investment of their contributions and the Company match into various investment options offered by the Plan. The Plan currently offers the Company's common stock and eighteen investment funds as investment options for participants. Contributions are subject to certain limitations. Participant Accounts Each participant's account is credited with the participant's contributions and allocations of the Company's contribution and plan earnings, 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. Vesting Participants are immediately vested in their voluntary contributions plus actual earning thereon. Vesting in the Company matching contributions plus actual earnings thereon is based on years of service. A participant is 100 percent vested after three years of credited service. A participant is automatically 100 percent vested in all contributions upon the attainment of age 65, upon becoming permanently disabled, or upon death while still an active participant. Due to the number of divestitures in 2002 and 2001, the Company may have experienced partial terminations. As a result, the Company has accelerated the vesting of all contributions for all participants involved in the divestitures. Participant Loans Participants may only borrow from their employee portion of fund accounts a minimum of $1,000 up to a maximum equal to $50,000 or 50% of the vested account balance, whichever is less. The term of the loan is generally five years except when use of the proceeds is for the purchase of a primary residence, for which the term can be up to 30 years. The loans are secured by the balance in the participant's account and bear interest at a rate commensurate with local prevailing rates as determined by the plan administrator. The interest rates on plan loans range from 5.25% to 7% at December 31, 2002. Principal and interest are repaid through payroll deductions. < 5 > Thermo Electron Corporation Choice Plan Notes to Financial Statements For the Years Ended December 31, 2002 and 2001 -------------------------------------------------------------------------------- Benefit Payments and Plan Withdrawals On termination of service due to death, disability or retirement, a participant (or beneficiary) may elect to receive either a lump-sum amount equal to the value of the participant's vested interest in his or her account or periodic instalments. For termination of service due to other reasons, a participant may receive the value of the vested interest in his or her account as a lump-sum distribution. Withdrawals may be made under certain other circumstances in accordance with the Plan document. Forfeitures Upon a participant's break in service, as defined, the nonvested portion of the participant's account is forfeited and is used to reduce the Company's future funding requirements. If a participant who has terminated employment is rehired by the Company before the greater of a five-year break in service or the number of the participant's years of service prior to the participant's break in service, the participant shall be reinstated in such forfeited amount. In 2002, employer contributions were reduced by $240,519 from forfeited nonvested accounts. Transfer In/Out In connection with certain reorganization activities at the Company, the assets of certain other plans sponsored by subsidiaries of the Company have been transferred into the Choice Plan in connection with the termination of those plans. Additionally, the reorganization has involved a number of business dispositions. As a result, the plan assets in the accounts of the affected employees have sometimes been transferred to plans sponsored by the acquirers of these businesses disposed. These transfers to and from other plans are captioned "net transfers to this plan" in the financial statements. 2. Summary of Significant Accounting Policies Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of plan assets and liabilities and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. Investment Valuation Investments are stated at fair value as determined by Fidelity Management Trust Company (the "Trust Company"), a trust company that is the trustee and custodian of the Plan's investment assets. Common shares are valued based on quoted market prices. Registered investment companies and bank collective investment funds are valued based on net asset value. Participant loans are valued at cost plus accrued interest, which approximates fair value. Payment of Benefits Benefits are recorded when paid. 3. Tax Status The Plan has received a favorable determination letter from the Internal Revenue Service dated May 15, 1995. The Plan has been amended since that date and a revised application for a determination letter is pending approval by the IRS; however, the plan administrator and Plan's tax counsel believe the Plan is currently designed and being operated in compliance with the applicable requirements of the Internal Revenue Code. < 6 > Thermo Electron Corporation Choice Plan Notes to Financial Statements For the Years Ended December 31, 2002 and 2001 --------------------------------------------------------------------------------------------------------------------------------- 4.

Interest income is recorded on the accrual basis. Dividends are recorded on ex-dividend date. 5. Related Party Transactions Plan investments are managed by the Trust Company, which is a trustee as defined by the Plan. Therefore, these transactions qualify as party-in-interest transactions. There were no fees paid by the Plan for investment management services for the period ended December 31, 2002. 6. Plan Termination Although it has not expressed an 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 employer contributions. 7. Administrative Expenses The Company pays for administrative expenses associated with management of and professional services for the Plan. Administrative fees for hardship withdrawals and loan transactions are paid by the participants. The administrative expenses included in the statement of changes in net assets available for benefits represent expenses paid by the participants. 8.

The balance of $14,627,249 for the net assets available for benefits as of May 31, 2002 was transferred into the Plan. On July 31, 2002, the Thermo Finnigan LLC 401(k) Plan was merged into the Plan.
