ITEM 4.  CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT

     On April 16, 2003, Deloitte & Touche LLP ("Deloitte") notified Registrant
that it did not intend to stand for reelection as Registrant's principal
independent accountant.

     The reports of Deloitte on Registrant's financial statements for the fiscal
years ended December 31, 2001 and 2000 have not included an adverse opinion or a
disclaimer of opinion, nor were they qualified or modified as to uncertainty,
audit scope, or accounting principles. However, as previously announced by
Registrant, the Audit Committee is currently conducting an investigation into
issues involving revenue recognition, which, upon completion of this
investigation, may materially impact the previously issued financial statements
and related reports.

     During the fiscal years ended December 31, 2001 and 2000 and the period
from January 1, 2002 to April 16, 2003, (a) there were no disagreements with
Deloitte on any matter of accounting principles or practices, financial
statement disclosure, or auditing scope or procedure, which disagreements, if
not resolved to the satisfaction of Deloitte, would have caused Deloitte to make
reference to the subject matter of the disagreements in connection with its
report, and (b) there were no "reportable events" as the term is defined in Item
304(a)(1)(v) of Regulation S-K. However, as previously announced by Registrant,
the Audit Committee is currently conducting an investigation into issues
involving revenue recognition, which, upon completion of this investigation, may
result in a determination that events requiring additional disclosure under Item
304(a)(1)(v) of Regulation S-K have occurred.

     Registrant has furnished Deloitte with a copy of the foregoing disclosures
and has requested Deloitte to furnish Registrant with a letter addressed to the
Securities and Exchange Commission stating whether it agrees with the above
statements and, if not, stating the respects in which it does not agree. A copy
of the letter, dated April 23, 2003, from Deloitte to the Securities and
Exchange Commission is attached to this Form 8-K as Exhibit 16.1.

ITEM 5.  OTHER EVENTS AND REQUIRED FD DISCLOSURE

     Reference is made to the press releases of Registrant, issued on April 22
and 23, 2003, which contain information meeting the requirements of this Item 5,
and which are incorporated herein by this reference. Copies of the press
releases are attached to this Form 8-K as Exhibits 99.1 and 99.2.

ITEM 7.  FINANCIAL STATEMENTS AND EXHIBITS

        (b) Pro Forma Financial Information. None.
