ITEM 5. OTHER INFORMATION

     Effective August 7, 2001, our Board of Directors approved the engagement of
Ernst & Young LLP as its independent accountants for the year ending December
31, 2001 to replace the firm of PricewaterhouseCoopers LLP ("PWC"), which was
dismissed as our independent accountants effective August 7, 2001. The Audit
Committee of our Board of Directors recommended the change of our independent
accountants to our Board of Directors, also effective August 7, 2001.

     PWC's reports on our consolidated financial statements for fiscal years
ended December 31, 1999 and 2000 did not contain an adverse opinion, disclaimer
of opinion, and were not qualified or modified as to uncertainty, audit scope or
accounting principles. During the fiscal years ended December 31, 1999 and 2000
and subsequent interim periods through August 7, 2001, there were no
disagreements with PWC on any matters of accounting principles or practices,
financial statement disclosure, or auditing scope and procedures which, if not
resolved to the satisfaction of PWC, would have caused PWC to make reference to
the matter in its reports. In addition, there were no reportable events during
this period, as described in Item 304(a)(1)(v) of the SEC's Regulation S-K,
except that PWC's Letter of Recommendations on Internal Controls for the year
ended December 31, 2000 identified a material weakness related to the resources
within our corporate accounting and finance department and recommended that the
Company hire new staff and establish additional procedures to facilitate the
proper recognition of revenue. We have hired additional staff and implemented
new policies and procedures that adequately address the issues raised in PWC's
letter.
