LONGMONT, COLORADO (SEPTEMBER 11, 1996)....... NexStar Automation, Inc. is
pleased to announce that at the extraordinary general meeting of shareholders
held in Vancouver today, the shareholders approved the proposed arrangement
under which NexStar shares are to be exchanged for shares of Zygo Corporation,
by a majority of approximately 92% of the shares voted. A total of 4,022,803 of
the approximately 5.4 million shares eligible to vote were voted at the meeting.

     The final exchange ratios will be one common share of Zygo Corporation for
22.0637 NexStar freely trading shares, and for 23.4849 NexStar escrowed shares
respectively.

     As indicated in the management information circular sent by NexStar to its

to the Supreme Court of British Columbia for a final order approving the
arrangement, and thereafter to file the court order with the Registrar of
Companies. It is presently expected that the arrangement will become final
shortly thereafter.

     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.
