Item 5.   Other Events
          ------------

          On April 24, 2000, Advanced Machine Vision Corporation  ("AMVC"),  Key
          Technology,  Inc.  ("Key"),  KTC  Acquisition  Corp.  ("KTC")  and FMC
          Corporation  ("FMC")  entered into an Agreement  whereby FMC agreed to
          vote its AMVC securities in favor of the previously  announced  merger
          of AMVC and Key. Such approval is a condition of Key's  obligations to
          effect  the  merger as set forth in the  Agreement  and Plan of Merger
          ("Merger Agreement") between AMVC and Key effective February 15, 2000.

          The Agreement provides for the following:

          1.   FMC agreed to vote its AMVC  securities in favor of the merger at
               the AMVC shareholders meeting.

          2.   At the  closing of the  merger,  FMC will  exchange  its  119,106
               shares of AMVC  preferred  stock into a like  number of shares of
               new Key Series C Preferred  Stock and 29,776 warrants to purchase
               Key  common  stock.   The  new  shares  have  a  $20  liquidation
               preference  and can be converted into Key common stock at $12 per
               share.  The Series C shares shall be redeemed at $20 per share in
               five  years.  FMC may also  "put"  the  shares to Key for $20 per
               share at any time. The warrants allow FMC to purchase  29,776 Key
               common  shares at $15 per  share,  or are  redeemable  at $10 per
               warrant for a total of $297,760.

          3.   At the closing of the  merger,  FMC will  exchange  its option to
               purchase  15%  of  AMVC's   outstanding  shares  into  an  option
               (expiring  October 14, 2003) to acquire for $2.52 million 210,000
               shares of Key's Series B Preferred  Stock,  which can be redeemed
               at $10 per share or can be converted into Key common stock at $15
               per share,  and a warrant to purchase 52,500 Key common shares at
               an  exercise  price  of $15  per  share.  The  warrants  will  be
