Changes in Registrant's Certifying Accountant. On April 26, 2002, our Board of Directors decided to no longer engage Luboshitz Kasierer, a Member Firm of Arthur Andersen, as our independent auditors and engaged Kost Forer & Gabbay, a member of Ernst & Young International, to serve as our independent auditors for the fiscal year 2002, in accordance with the recommendation of the Board's Audit Committee. The determination to change independent auditors followed our decision to seek proposals from independent public accountants to audit our financial statements for the fiscal year ending December 31, 2002. The appointment of Kost Forer & Gabbay is subject to shareholder ratification at the 2002 Annual Meeting of Shareholders to be held in June. Luboshitz Kasierer's audit reports on our consolidated financial statements for each of the fiscal years ended December 31, 2001 and 2000 did not contain an adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles. During our two fiscal years ended December 31, 2001 and 2000 and the subsequent interim period preceding the decision to change independent public accountants, there were no disagreements with Luboshitz Kasierer on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure which, if not resolved to Luboshitz Kasierer's satisfaction would have caused them to make reference to the subject matter of the disagreement in connection with the audit reports on our consolidated financial statements for such years, and there were no reportable events as defined in Item 304(a) (1) (v) of Regulation S-K. We provided Luboshitz Kasierer with a copy of the foregoing disclosures. Attached as Exhibit 16.1 is a copy of Luboshitz Kasierer's letter, dated April 29, 2002, stating its agreement with such statements. In the years ended December 31, 2001 and 2000 and through the date hereof, we did not consult Kost Forer & Gabbay with respect to the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on our consolidated financial statements, or any other matters or reportable events as set forth in Items 304(a) (2) (i) and (ii) of Regulation S-K.
