                           ZYGO CORPORATION COMPLETES
                     ACQUISITION OF NEXSTAR AUTOMATION, INC.

MIDDLEFIELD, CONNECTICUT (SEPTEMBER 13, 1996).......Zygo Corporation
(NASDAQ:ZIGO) today announced that it has completed the acquisition of NexStar
Automation, Inc. ("NexStar"), a Canadian company that was publicly traded on the
Vancouver Stock Exchange. NexStar shareholders voted on September 11th to
approve the acquisition at an extraordinary meeting. In the transaction, which
was structured as a statutory plan of arrangement under Canadian law, Zygo
acquired all the outstanding shares of NexStar in exchange for 250,000 shares of
Zygo's common stock. The acquisition will be accounted for as a pooling of
interests.

     NexStar is engaged in the business of designing, developing and
manufacturing automation and parts handling equipment to improve production
efficiency and manufacturing yields within the data storage, semiconductor and
medical disposables markets. Its operations are located in Longmont, Colorado.

     Gary K. Willis, president and chief executive officer of Zygo, noted, "The
addition of NexStar will strengthen our capability to fully automate the test
and measurement process for our customers. NexStar's parts handling capability
is expected to see




significantly increased demand as piece parts continue to become smaller and
handling those parts without human intervention becomes more critical in a
variety of industries. Like Zygo, the data storage industry has been a primary
market focus for NexStar with NexStar's emphasis on the disk side of the
industry, and Zygo's emphasis on the head side. The combination will result in
access to major new opportunities." Ahmad Akrami, president of NexStar, added,
"Our merger with Zygo will provide our company with the resources which should
allow us to realize our potential much faster than as a standalone enterprise.
The fit with Zygo is very good; our technologies, our people, our focus on
quality and the customer, and our markets are all very much aligned, and we are
all looking forward to working together as a team."

     Shareholders who have not tendered the certificates for their NexStar
shares to Montreal Trust Company in Vancouver, accompanied by a properly
executed Letter of Transmittal, are urged to do so as soon as possible so as to
ensure that they receive certificates for the Zygo shares to which they are
entitled, without delay.

     Zygo Corporation designs, develops, manufactures and markets precision
measurement and automation equipment and components used to enhance production
yields in high technology industries. The firm is based in Middlefield,
Connecticut, and also has operations in Sunnyvale, California, and Longmont,
Colorado.
