CHANGES TO REGISTRANT'S CERTIFYING ACCOUNTANTS. On July 8, 2002, Bio-Rad Laboratories, Inc. ("Bio-Rad") dismissed Arthur Andersen LLP ("Andersen") as its independent public accountants, and appointed Deloitte & Touche LLP ("Deloitte & Touche") as its new independent public accountants. The decision to change independent public accountants was recommended by the Audit Committee and approved by the Board of Directors of Bio-Rad. The report of Andersen for the fiscal years ended December 31, 2001 and 2000 contained no adverse opinions, disclaimer of opinion or qualifications or modification as to uncertainty, audit scope or accounting principles. During the fiscal years ended December 31, 2001 and 2000, and the interim period from January 1, 2002 through July 8, 2002 there were no disagreements between Bio-Rad and Andersen on any accounting principles or practices, financial statement disclosure or auditing scope or procedure, which, if not resolved to the satisfaction of Andersen would have caused it to make reference to the subject matter of the disagreement in connection with its report. No event described in paragraph (a)(1)(v) of Item 304 of Regulation S-K has occurred within Bio-Rad's fiscal years ending December 31, 2001 and 2000 or the period January 1, 2002 through July 8, 2002. Bio-Rad has provided Andersen with a copy of the foregoing disclosures and requested a letter from Andersen addressed to the Securities and Exchange Commission stating whether it agrees with such statements. Andersen has orally advised the Company that due to recent events impacting Andersen's infrastructure it is unable to issue such a letter. Bio-Rad did not consult with Deloitte & Touche during the fiscal years ended December 31, 2001 and 2000, and the interim period from January 1, 2002 through July 8, 2002 on any matter which was the subject of any disagreement or any reportable event or on the application of accounting principles to a specified transaction, either completed or proposed.
