       CERTIFICATION OF SENIOR VICE PRESIDENT AND CHIEF FINANCIAL OFFICER

I, David L. White, certify that:

               1.   I have reviewed this Amendment No. 1 to the annual report on
     Form 10-K of Asyst Technologies, Inc.;

               2.   Based on my knowledge, this report does not contain any
     untrue statement of a material fact or omit to state a material fact
     necessary to make the statements made, in light of the circumstances under
     which such statements were made, not misleading with respect to the period
     covered by this report;

               3.   Based on my knowledge, the financial statements, and other
     financial information included in this report, fairly present in all
     material respects the financial condition, results of operations and cash
     flows of the registrant as of, and for, the periods presented in this
     report;

               4.   The registrant's other certifying officer and I are
     responsible for establishing and maintaining disclosure controls and
     procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for
     the registrant and have:


               (a) designed such disclosure controls and procedures, or caused
     such disclosure controls and procedures to be designed under our
     supervision, to ensure that material information relating to the
     registrant, including its consolidated subsidiaries, is made known to us by
     others within those entities, particularly during the period in which this
     report is being prepared;

               (b) evaluated the effectiveness of the registrant's disclosure
     controls and procedures and presented in this report our conclusions about
     the effectiveness of the disclosure controls and procedures, as of the end
     of the period covered by this report based on such evaluation; and

               (c) disclosed in this report any change in the registrant's
     internal control over financial reporting that occurred during the
     registrant's most recent fiscal quarter (the registrant's fourth fiscal
     quarter in the case of an annual report) that has materially affected, or
     is reasonably likely to materially affect, the registrant's internal
     control over financial reporting; and

               5.   The registrant's other certifying officer and I have
     disclosed, based on our most recent evaluation of internal control over
     financial reporting, to the registrant's auditors and the audit committee
     of the registrant's board of directors (or persons performing the
     equivalent functions):

               (a) all significant deficiencies and material weaknesses in the
     design or operation of internal control over financial reporting which are
     reasonably likely to adversely affect the registrant's ability to record,
     process, summarize and report financial information; and

               (b) any fraud, whether or not material, that involves management
     or other employees who have a significant role in the registrant's internal
     control over financial reporting.

                               Date: October 29, 2003
                               /s/ David L. White
                               _____________________________________
                               David L. White,
                               Senior Vice President and
                               Chief Financial Officer
