CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT. On April 2, 2002, Asyst Technologies, Inc. ("Asyst" or the "Registrant") terminated the engagement of its current independent public accountant, Arthur Andersen LLP. This termination followed Asyst's decision to seek proposals from other independent auditors to audit Asyst's consolidated financial statements for its fiscal year ended March 31, 2002. On April 2, 2002, the Board of Directors, based on the recommendation of the Audit Committee, retained PricewaterhouseCoopers LLP as its independent auditors with respect to the audit of Asyst's consolidated financial statements for its fiscal year ended March 31, 2002. During Asyst's two most recent fiscal years ended March 31, 2001, and during the subsequent interim period preceding the replacement of Arthur Andersen LLP, there was no disagreement between Asyst and Arthur Andersen LLP on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure which, if not resolved to Arthur Andersen LLP's satisfaction, would have caused Arthur Andersen LLP to make reference to the subject matter of the disagreement in connection with its reports. The audit reports of Arthur Andersen LLP on the consolidated financial statements of Asyst as of and for the last two fiscal years ended March 31, 2001 did not contain any adverse opinion or disclaimer of opinion, nor were these opinions qualified or modified as to uncertainty, audit scope or accounting principles. A letter from Arthur Andersen LLP is attached hereto as Exhibit 16.1. During Asyst's two most recent fiscal years ended March 31, 2001, and during the subsequent interim period preceding the replacement of Arthur Andersen LLP, Asyst has not consulted with PricewaterhouseCoopers LLP regarding the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on Asyst's financial statements.
