Item 4.     Changes in Registrant's Certifying Accountant

            On June 21, 2002, the Audit Committee of the Board of Directors of
Thermo Electron Corporation (the "Company") decided to no longer engage Arthur
Andersen LLP ("Arthur Andersen" or "AA") as the Company's independent public
accountants and engaged PricewaterhouseCoopers LLP ("PwC") to serve as the
Company's independent public accountants for the fiscal year 2002.

            Arthur Andersen's reports on the Company's consolidated financial
statements for each of the last two completed fiscal years did not contain an
adverse opinion or disclaimer of opinion, nor were they qualified or modified as
to uncertainty, audit scope or accounting principles, except for an explanatory
paragraph concerning the adoption of Staff Accounting Bulletin No. 101, "Revenue
Recognition in Financial Statements," and Statement of Financial Accounting
Standards No. 133, "Accounting for Derivative Instruments and Hedging
Activities."

            During the last two completed fiscal years and through the date
hereof, there were no disagreements with Arthur Andersen on any matter of
accounting principle or practice, financial statement disclosure, or auditing
scope or procedure which, if not resolved to AA's satisfaction, would have
caused them to make reference to the subject matter in connection with their
report on the Company's consolidated financial statements for such years; and
there were no reportable events as defined in Item 304(a)(1)(v) of Regulation
S-K.

            The Company provided Arthur Andersen with a copy of the foregoing
disclosures. Attached as Exhibit 16 is a copy of AA's letter, dated June 25,
2002, stating its agreement with such statements.

            During the last two completed fiscal years and through the date
hereof, the Company did not consult PwC with respect to the application of
accounting principles to a specified transaction, either completed or proposed,
or the type of audit opinion that might be rendered on the Company's
consolidated financial statements, or any other matters or reportable events as
set forth in Items 304(a)(2)(i) and (ii) of Regulation S-K.
