Item 2. Acquisition or Disposition of Assets

         On August 2, 1999,  Pinnacle  Systems,  Inc., a California  corporation
(the "Company" or "Pinnacle"), completed the purchase ("Purchase") of certain of
the assets and the assumption of certain liabilities of the Video Communications
Division of Hewlett-Packard Company, a Delaware corporation ("HP"). The Purchase
was made  pursuant to the terms and  conditions of an Asset  Purchase  Agreement
dated June 30, 1999 (the  "Agreement").  Under the terms of the  Agreement,  the
Company paid  approximately  $12.6 million in cash and issued  773,172 shares of
its common  stock valued at $19.0  million.  In  addition,  the Company  assumed
liabilities  of  approximately  $2.0  million.  The  Company  expects  to  incur
approximately  $1.0 million in costs  associated  with executing the transaction
and integrating the businesses.  The Company will account for the acquisition as
a purchase and  currently  anticipates  that  approximately  $6.5 million of the
purchase price will be charged as in-process  research and development and other
non-recurring costs in the quarter ending September 30, 1999. In connection with
the Purchase, Pinnacle hired 55 employees of HP's Video Communications Division.
The purchase price was determined  through an arm's-length  negotiation  between
the parties.

         HP's   Video   Communications    Division   manufactures    MPEG2-based
broadcast-quality  video servers.  During a six-month transition period, HP will
continue to operate the  engineering  and  manufacturing  operations  as well as
support and certain sales  operations  located in Europe and Asia. At the end of
the transition period,  the engineering and manufacturing  organizations will be
merged into  Pinnacle's  Mountain  View,  California  facility and the sales and
customer support organizations integrated into Pinnacle's existing networks.
