Item 4.  Changes in Registrant's Certifying Accountant.
------   ---------------------------------------------

     Effective June 17, 2002, upon the recommendation of its Audit Committee,
the Board of Directors of the registrant (i) rescinded its previous selection of
Arthur Andersen LLP to examine the financial statements of and to serve as the
independent accountants for the registrant and its subsidiaries for 2002 and
(ii) selected KPMG LLP to audit the financial statements of the registrant and
its subsidiaries for 2002.

     Arthur Andersen LLP audited the registrant's financial statements for 2000
and 2001.  The reports of Arthur Andersen LLP on such financial statements did
not contain an adverse opinion or a disclaimer of opinion and were not qualified
or modified as to uncertainty, audit scope, or accounting principles.

     During the registrant's two most recent fiscal years (2000 and 2001) and
the subsequent interim period through June 17, 2002, there were no disagreements
with Arthur Andersen LLP on any matter of accounting principles or practices,
financial statement disclosure, or auditing scope or procedure; and during such
periods there was no reportable event, as described in Item 304(a)(1)(v) of
Regulation S-K.

     During the registrant's two most recent fiscal years (2000 and 2001) and
the subsequent interim period through June 17, 2002, the registrant did not
consult KPMG LLP regarding any of the matters referred to in Item 304(a)(2) of
Regulation S-K.

     The letter required by Item 304(a)(3) of Regulation S-K accompanies this
Form 8-K as Exhibit 16.1.
