                    PSC AND PERCON ANNOUNCE MERGER AGREEMENT

Rochester, New York--November 10, 1999--PSC Inc. (Nasdaq:PSCX),  a global leader
in  the   manufacture   and   marketing  of  bar  code  scanning  and  automatic
identification solutions and Percon Incorporated  (Nasdaq:PRCN),  a manufacturer
of wireless and batch portable data terminals,  decoders, input devices and data
management application software, located in Eugene, Oregon, today announced they
have entered into a merger agreement. The transaction, which was approved by the
board of  directors  of each  company,  is  subject  to Percon  shareholder  and
regulatory approvals.

PSC will pay $15.00 in cash for each outstanding share of Percon common stock.

Robert C.  Strandberg  will  retain his  position as PSC's  President  and Chief
Executive Officer.  Andy J. Storment,  Percon's  Executive Vice President,  will
join PSC and will direct the  Company's  portable  data  terminal  and  software
businesses.  Michael P. Coughlin, Percon's President and CEO, will assist PSC in
a  consulting   capacity   regarding  sales  channel   strategies  and  business
development opportunities.

"This  acquisition  provides  significant  benefits  for  PSC  shareholders  and
customers,  primarily because it immediately expands our product line beyond bar
code  scanning into  complementary  and  fast-growing  segments of the automatic
identification  and data  capture  industry,"  said  Robert C.  Strandberg,  PSC
President  and  CEO.  "Together  we will  have  broader  distribution  for  both
companies' product sets and the opportunity to reduce costs, as we capitalize on
the strengths of each company."

Michael P.  Coughlin,  Percon's  President and CEO,  said,  "We are very excited
about our merger with PSC.  Percon's  wireless  systems fit very well with PSC's
scanner  product  line and will  enable  us to offer  complete  data  collection
solutions to customers."
