ITEM 4.  CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT

     On April 23, 2003, Registrant engaged BDO Seidman, LLP ("BDO") as its new
principal independent accountant to audit Registrant's financial statements for
the fiscal year ending December 31, 2003.

     During the two most recent fiscal years and through April 22, 2003, the
Company has consulted with BDO on the following:

     On March 27, 2003, the law firm of Morgan, Lewis & Bockius, LLP as counsel
to the Audit Committee of Registrant engaged BDO to assist the Audit Committee
with its investigation related to certain sales transactions for fiscal 2002 and
the 4th quarter of 2001. As a result of the work preformed, BDO has orally
communicated to Registrant that it believes certain sales transactions (the
"Transactions") were not recorded in the proper period.

     There were no other written or oral consultations between Registrant and
BDO regarding either the specific application of accounting principles or the
type of audit opinion that might be rendered on Registrant's financial
statements that was considered an important factor by Registrant in reaching a
decision as to an accounting, auditing or financial reporting issue, or any
other matter that was the subject of a disagreement or a reportable event, that
would have required disclosure under Item 304(a)(2) of Regulation S-K.

     The Company is consulting with Deloitte & Touche LLP ("Deloitte") with
regard to the Transactions.

     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 29, 2003, from Deloitte to the Securities and
Exchange Commission is attached to this Form 8-K as Exhibit 16.1.
