                 WHITE PINE SOFTWARE TO ACQUIRE T.120 TECHNOLOGY

     ACQUISITION OF ASSETS OF LABTAM COMMUNICATIONS ADDS DATA COLLABORATION
CAPABILITIES, EXTENDING WHITE PINE'S LEADERSHIP IN MULTIMEDIA CONFERENCING

NASHUA, New Hampshire - July 20, 1998 - White Pine Software, Inc. 
(NASDAQ:WPNE), a leading provider of multimedia conferencing applications for 
the Internet and intranets, today announced it has signed a definitive 
agreement to acquire assets and intellectual property, including T.120 
whiteboarding and data collaboration technology, from privately-held Labtam 
Communications Pty of Victoria, Australia. Terms of the agreement were not 
disclosed.

White Pine Software -- maker of CU-SeeMe(R), MeetingPoint(TM), and 
ClassPoint(TM) -- plans to incorporate this key technology into its 
MeetingPoint and ClassPoint conferencing solutions. T.120 is the protocol 
that defines whiteboarding, application sharing and data collaboration for 
multipoint conferencing applications.

"From a strategic standpoint, this acquisition is very important as we continue
to evolve our products into multimedia conferencing applications tailored to
business, education, and training," said Killko Caballero, president of White
Pine Software. "By acquiring this technology, White Pine is strengthening its
H.323-related technology capital and has reinforced its commitment to open
standards. We are extending our reach to new levels of data and bringing a core
competency in-house that will enable tighter integration between T.120 and H.323
for faster and better delivery of solutions as we continue to develop
conferencing applications for both business and education." This acquisition of
T.120 technology complements White Pine's recent announcement regarding the
integration of Microsoft NetMeeting's whiteboarding and application sharing
features into its ClassPoint distance learning product.
