              Asyst Technologies Announces Strategic Alliance with
                         Japanese Robotic Company MECS

Proposed transaction strengthens Asyst's fab automation solutions for the global
      semiconductor industry while expanding its direct presence in Japan

TOKYO, Japan, Sept.  22, 1999 - Asyst Technologies, Inc. (Nasdaq NM: ASYT), a
leading supplier of advanced manufacturing solutions for the semiconductor
industry, today announced a strategic alliance with Nagoya-based MECS Corp.-one
of Japan's leading suppliers of robotic systems used to automate today's
sophisticated semiconductor and flat panel display manufacturing tools.  The two
companies will cooperate in many areas, including joint product development,
marketing and support for the growing installed base of Asyst products in Japan.
Under terms of the agreement, Asyst will take a minority share ownership in
MECS. In addition, Asyst has agreed to acquire a majority interest in MECS upon
attainment by MECS of certain business objectives.  Asyst and MECS believe that
these goals may be achieved in the three to six month time frame.

According to Asyst Chairman and Chief Executive Officer Mihir Parikh, the MECS
transaction is the latest in a series of strategic acquisitions and partnerships
designed to enhance Asyst's comprehensive portfolio of value assurance systems
and technologies.  "The MECS tool set complements Asyst's existing robotic
technologies with systems that enable high-speed precision wafer handling at a
low cost of ownership.  This transaction exemplifies Asyst's commitment to
continually broaden its product portfolio with innovative technologies that
optimize both regional and global chipmakers' ability to protect the integrity
of their wafers throughout the manufacturing cycle."

Commenting on the synergy between the two organizations, MECS president Kazuo
Kimata noted, "MECS has positioned itself as a leading supplier of robotic
solutions in Japan, while Asyst is a global leader in tool automation.  Our
cooperative efforts better position MECS and Asyst to provide Japanese IC makers
with the latest and most complete automation solution set in Japan."

Strategic alliance expands Asyst's presence in Japan

The Asyst/MECS partnership will greatly expand Asyst's direct presence in Japan.
With revenues of $4.7 billion yen ($43 million U.S. for the year ending March
1999), five locations throughout the country and 160 employees, MECS has the
critical mass necessary to handle all regional engineering, manufacturing and
system-integration services for Asyst's full line of isolation and automation
products.  This includes the recently introduced Asyst PlusTM Portal, which
provides a turnkey, tool-automation front-end solution for today's most advanced
semiconductor process tools.  "Asyst's ability to provide local design,
manufacturing, integration and support services through MECS will be of critical
importance as the Japanese semiconductor market steps through its next growth
phase," explained Parikh.

Industry analysts indicate that Japan's semiconductor industry is showing
increased strength.  Supporting this trend, a quarter-to-quarter comparison of
semiconductor equipment sales into Japan from VLSI Research, Inc. show that
sales were up 40 percent in the second calendar

                                       1


quarter 1999, compared with the same quarter in 1998. Sales of equipment were
nearly $1.13 billion in the second quarter 1999 compared with $805 million for
the same period in 1998.

Asyst is already capitalizing on this growth as both new and existing Japanese
labs turn to Asyst for their isolation and automation solutions.  Since March
1999, Asyst has booked orders worth multimillions of dollars from Japan's
leading chip manufacturers, which are either upgrading older labs for 0.25
micron device production or equipping new fabs for 0.18 micron technology.

Asyst reports that leading equipment manufacturers in Japan present a second,
and equally compelling, market opportunity for Asyst.  Like its U.S. and
European counterparts, these toolmakers are increasingly turning to outside
contractors to not only automate their tools, but to develop complete tool
front-end solutions that enable seamless integration between original equipment
manufacturer (OEM) production tools and advanced fab automation systems.  Asyst
aggressively supports this market need with a comprehensive portfolio of tool
automation and Asyst Plus Portals, which are complete tool front-end solution
sets.  Through its partnership with MECS, Asyst has an even stronger platform
for supporting and attracting major OEM and IC manufacturing customers.  In
addition, the ability to provide full regional factory support will ensure that
these technologies are both tailored and optimized to meet the unique needs of
the region.
