Letter to Resellers regarding merger mailed on November 14, 2000.

Late last week Active Voice (Pronexus' parent company) and Cisco each announced
that Cisco Systems, Inc. intends to acquire the Active Voice Corporation. This
is exciting news and creates significant market growth potential (For more
details, please see the press release on the front page of Active Voice's Web
site at www.activevoice.com).

Cisco plans to make Active Voice's Unity(TM) product line a key component of
its IP-based Architecture for Voice, Video and Integrated Data (AVVID) family of
solutions.

Cisco also intends to spin off Active Voice's traditional voice messaging
business into a new self-operating entity. This organization will continue to
sell and support Repartee(R), PhoneSoft(TM), Lingo(TM), Replay(R), Replay
Plus(R), embedded solutions, and other non-Unity products and services.
Pronexus, Inc. will be part of this new entity and will continue to operate as a
subsidiary. Pronexus will retain its head offices in Kanata, Ontario, Canada. We
understand that as a long-time partner of Pronexus solutions, you will have
questions about this important announcement. As we are able to share additional
details regarding the announcement, we will communicate this information to you
as quickly as possible. In the meantime, we're going forward with business as
usual.

Thank you for your ongoing commitment to Pronexus Inc. Our success would not
have been possible without all the hard work and effort that you have put in.

Sincerely,

Gary T. Hannah
President, Pronexus Inc.
