ITEM 4.  CHANGE OF ACCOUNTANTS

      On May 15, 2002, Arthur Andersen LLP informed us that it would no longer
be able to serve as our independent public accountants, and therefore the Board
of Directors, upon recommendation of the Audit Committee, dismissed Arthur
Andersen LLP as our independent public accountants effective as of the close of
business on May 15, 2002. We intend to initiate an interview process to obtain
new accountants to serve as our independent public accountants for 2002.

      Arthur Andersen LLP has been our independent public accountants since 1986
and their report on our financial statements for the fiscal years ended December
31, 2001 and 2000 contains no adverse opinion or disclaimer of opinion and was
not qualified or modified as to uncertainty, audit scope or accounting
principles. During our two most recent fiscal years and through May 15, 2002, we
have not had any disagreements with Arthur Andersen LLP on any matter of
accounting principles or practices, financial statement disclosure or auditing
scope or procedure, nor any reportable events (as defined in Regulation S-K Item
304(a)(1)(v)).

      We provided Arthur Andersen LLP with a copy of this disclosure and
requested that Arthur Andersen furnish us with a letter addressed to the
Securities and Exchange Commission stating whether it agrees with the above
statements and, in response to our request, Arthur Andersen LLP has delivered a
letter to the Securities and Exchange Commission, dated May 15, 2002, a copy of
which is filed as Exhibit 16.1 to this Form 8-K.

ITEM 7. EXHIBITS
