                 BROADVISION COMPLETES ACQUISITION OF INTERLEAF,
                              THE E-CONTENT COMPANY

         REDWOOD  CITY,  Calif.,  April 17, 2000 -  BroadVision,  Inc.  (Nasdaq:
BVSN), a leading  worldwide  supplier of personalized  e-business  applications,
announced  it  has  completed  the  acquisition  of  Interleaf,  Inc.  including
Interleaf's  e-content(TM)business  dedicated to the development,  marketing and
sale of  XML-based  content  management  tools and WAP  technology  for wireless
delivery of content. The acquisition closed on April 14, 2000.

         On January 26, 2000,  BroadVision  announced a definitive  agreement to
acquire  Interleaf  pursuant  to a  statutory  merger.  Under  the  terms of the
agreement and after giving effect to  BroadVision's  3-for-1 stock split paid in
March 2000, each outstanding  share of Interleaf common stock now represents the
right to  receive  1.0395  shares of  BroadVision  common  stock.  In  addition,
BroadVision  assumed all outstanding options to purchase Interleaf common stock.
Based on the number of Interleaf shares and Interleaf options  outstanding as of
the close of the acquisition, BroadVision will issue (or reserve for issuance on
the exercise of Interleaf options) a total  approximately 16.8 million shares of
its common  stock.  Interleaf  common stock  ceased  trading on The Nasdaq Stock
Market at the close of market on April 14, 2000.

         The acquisition, which will be accounted for as a purchase, is intended
to qualify as a tax-free reorganization for Interleaf shareholders.

         "This acquisition will add significant wireless technology capabilities
and  substantially   increase  our  ability  to  provide  enhanced  personalized
e-business  applications  across  multi-touch  points,"  said Dr.  Pehong  Chen,
president  and CEO of  BroadVision,  Inc.  "Interleaf's  expertise  in  wireless
solutions  combined with  BroadVision's  leadership in providing a comprehensive
suite of  integrated  and  personalized  e-business  applications  creates a new
powerhouse  emphasizing  both  companies'  synergies  for  delivering  the total
experience from Web to wireless for customers,  partners and  employees."
