        ASYST TECHNOLOGIES, INC. ANTICIPATES LOWER THAN EXPECTED REVENUE
                        FOR FIRST QUARTER OF FISCAL 1999
                   COMPANY ANNOUNCES SHAREHOLDER RIGHTS PLAN
                                        
FREMONT, Calif., June 25, 1998 Asyst Technologies, Inc. (Nasdaq:ASYT), the
leading supplier of manufacturing automation and Standard Mechanical InterFace
(SMIF) isolation to the global semiconductor industry, announced today that it
expects to report lower than anticipated total revenue for the first quarter
fiscal year 1999 ending June 27, 1998.  The Company expects to report revenue
for the first quarter in the range of $32 to $35 million.

"Visibility remains very limited and business has recently weakened further,"
said Dr. Mihir Parikh, chairman and chief executive officer.  "As a result, we
have seen a softening of orders.  Due to the uncertain outlook in Asia at this
time, it is likely that revenue for the second quarter of fiscal 1999 (September
end) will be lower than in the first fiscal quarter.

"We feel it prudent to continue with the steps previously planned to reduce our
expense growth in the near term, while continuing to invest in critical
strategic areas.  Despite the present uncertain outlook for fiscal 1999, we
believe that we are positioned to rebound quickly upon return of normal market
conditions given our strategic position in providing customers with a complete
tool automation solution," concluded Parikh.

These statements are preliminary.  The Company plans to announce actual results
for the first quarter on July 22, 1998 after the close of market.

In further developments, the Company's Board of Directors approved the adoption
of a Shareholder Rights Plan under which all shareholders of record as of July
10, 1998 will receive rights to purchase shares of a new series of Preferred
Stock.

The Rights Plan is designed to enable all Asyst shareholders to realize the full
value of their investment and to provide for fair and equal treatment for all
shareholders in the event that an unsolicited attempt is made to acquire Asyst.
The adoption of the Rights Plan is intended as a means to guard against abusive
takeover tactics and is not in response to any particular proposal.

The rights will be distributed as a non-taxable dividend and will expire in 10
years from the Record Date.  The rights will be exercisable only if a person or
group acquires 15 percent or more of the Asyst Common Stock or announces a
tender offer for 15 percent or more of the Common Stock.  If a person acquires
15 percent or more of Asyst's Common Stock, all rightsholders except the buyer
will be entitled to acquire Asyst Common Stock at a discount.  The effect will
be to discourage acquisitions of more than 15 percent of Asyst's Common Stock
without negotiations with the Board.

The rights will trade with Asyst's Common  Stock, unless and until they are
separated upon the occurrence of certain future events.  The rights distribution
is not taxable to the shareholders.  Asyst's Board of Directors may terminate
the Rights Plan at any time or redeem the rights prior to the time a person
acquires more than 15 percent of the Asyst Common Stock.  Additional details
regarding the Rights Plan will be outlined in a summary to be mailed to all
shareholders following the Record Date.

Except for statements of historical fact, the statements in this press release
are forward-looking.  Such statements are subject to a number of risks and
uncertainties that could cause actual results to differ materially from the
statements made.  These factors include, but are not limited to, general
economic conditions, semiconductor industry cycles, risks associated with the
acceptance of new products and product capabilities, and other factors more
fully detailed in the Company's most recent Forms 10-K annual report and 10-Q
quarterly report on file with the SEC.
