Intrado Announces Agreements with Leading Location Determination Technology Vendors; Agreements Highlight Growing Importance of

Intrado Inc. (NASDAQ: TRDO), a global provider of
integrated data and telecommunications solutions and leading provider
of VoIP 9-1-1 services, today announced agreements with three leading
location determination technology vendors, Rosum Corporation, S5
Wireless, Inc. and Skyhook Wireless Inc. The agreements reflect the
growing importance of location determination in VoIP E9-1-1 service
delivery. Intrado will work with these companies to demonstrate a
range of location determination solutions and their ability to
integrate into Intrado(R) V9-1-1(R) Services.
   "As VoIP moves towards fixed mobile convergence, location
determination will become a fundamental component within the
IP-enabled communications market," said Stephen Meer, Intrado chief
technology officer and co-founder. "Intrado continues to anticipate
the needs of the VoIP E9-1-1 market and to make sure that we have the
necessary solutions in place. The framework we are developing supports
the continued progression of a more mobile-oriented VoIP solution that
can be deployed with any device, in any location at any time."

solution that allows VoIP service providers to support their
increasingly mobile subscribers. By establishing these relationships,
Intrado is leading early efforts to transcend the need for subscribers
to self provision their location information and instead create an
environment where communication devices can automatically determine
their location for 9-1-1 call routing purposes.

   About S5

   S5 Wireless creates location technology that's right on the money.
Founded in 2003, S5 Wireless has developed a new low-cost technology
for locating and tracking important items indoors or outdoors with the
accuracy of GPS, anywhere in the coverage area. Costing under a
dollar, and with years of potential battery life, the S5 chip can be
attached or embedded in consumer, industrial, military or
communications devices and transmit critical location and telemetry
information when it's needed. VoIP callers, for example, can use S5
technology to automatically route their 911 calls to the nearest
emergency dispatcher and pinpoint their precise location for
first-responders. Visit S5's company Web site at www.S5W.com, or
