ITEM 4.  CHANGES IN THE REGISTRANT'S CERTIFYING ACCOUNTANT

     As discussed in the Company's Current Report on Form 8-K filed on April 23,
2003, on April 16, 2003, Deloitte and Touche LLP, which we refer to in this
report as Deloitte, informed the Company that it did not intend to stand for
reelection as the Company's principal independent accountant.

     On July 16, 2003, Deloitte advised the Company that the client-auditor
relationship between the Company and Deloitte had ceased.

     The reports of Deloitte on the Company's financial statements for the
fiscal years ended December 31, 2002 and 2001 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, except for the 2002 report
which contained an explanatory paragraph relating to a going concern
uncertainty.

     During the fiscal years ended December 31, 2002 and 2001 and the period
from January 1, 2003 to July 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, except as follows:

     Deloitte informed the Company that material weaknesses in the Company's
internal controls existed. Specifically, Deloitte advised the Company that:

     o    The Company's accounting and finance staff are inadequate to meet the
          needs of a complex, multinational SEC registrant. The Company needs to
          strengthen its capability to implement existing generally accepted
          accounting principles, as well as understand and implement new
          accounting standards. In addition, the Company needs to strengthen its
          capabilities in performing routine accounting processes involved in
          closing its books, such as account reconciliations and analyses.

     o    The Company needs to strengthen its controls and processes related to
          revenue recognition. During 2002, 2001 and 2000, revenue was
          recognized for transactions that did not meet the requirements for
          revenue recognition under the Company's policies or generally accepted
          accounting principles.

     The Company has furnished Deloitte with a copy of the foregoing disclosures
and has requested Deloitte to furnish the Company 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 July 22, 2003, from Deloitte to the Securities and Exchange
Commission is attached to this Current Report on Form 8-K as Exhibit 16.1.
