Changes in Registrant's Certifying Accountant. On June 24, 2002, the Board of Directors of Hologic, Inc. ("Hologic"), based upon the recommendation of Hologic's Audit Committee, approved the dismissal of Arthur Andersen LLP ("Arthur Andersen"), as its independent auditors, and the engagement of Ernst & Young LLP to serve as its new independent auditors for fiscal 2002. The change in auditors became effective as of June 24, 2002. The reports of Arthur Andersen on Hologic's consolidated financial statements for each of the fiscal years ended September 29, 2001 and September 30, 2000 did not contain an adverse opinion or disclaimer of opinion nor were they qualified or modified as to uncertainty, audit scope or accounting principles. During the fiscal years ended September 29, 2001 and September 30, 2000 and through the date hereof, there were no disagreements with Arthur Andersen on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which, if not resolved to the satisfaction of Arthur Andersen, would have caused Arthur Andersen to make reference to the subject matter of the disagreement in connection with their report on the financial statements for such years. In addition, during the fiscal years ended September 29, 2001 and September 30, 2000 and through the date hereof, there were no reportable events as defined in Item 304(a)(1)(v) of Regulation S-K. Hologic provided Arthur Andersen with a copy of the foregoing disclosures prior to the filing of this Current Report on Form 8-K with the Securities and Exchange Commission and requested Arthur Andersen to furnish it with a letter addressed to the Securities and Exchange Commission stating whether Arthur Andersen agrees with the statements made by Hologic herein and, if not, stating the respects in which it does not agree. Attached hereto as Exhibit 16 is a copy of Arthur Andersen's letter, dated June 27, 2002, stating its agreement with such statements. As mentioned above, simultaneously with the dismissal of its former auditors, Hologic engaged Ernst & Young LLP to act as its independent auditors as successor to Arthur Andersen for fiscal 2002 effective as of June 24, 2002. During the fiscal years ended September 29, 2001 and September 30, 2000 and through the date hereof, Hologic did not consult with Ernst & Young LLP regarding any matters or events set forth in Items 304(a)(2)(i) or (ii) of Regulation S-K.
