Item 4. 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.
