Canadian Carrier TELUS Signs Multi-Year Agreement With Acision to Provide Advanced Messaging Solution

Mobile Data Leader to Deploy "Best of Breed" Messaging Platform Across TELUS' Multiple Mobile Network Technologies

TORONTO, September 20, 2010 - Acision, a world leader in mobile data, today announced that TELUS has
signed a multi-year agreement to use Acision's advanced messaging solution
across the company's multiple mobile network technologies, including CDMA
2000, UMTS, HSPA+ and iDEN.

With Canadian text messaging traffic growing in 2009 at a year-over-year
rate of 70 percent *, Acision's technology will help TELUS accommodate the
surge in SMS traffic and address new market opportunities by providing a high
value messaging service to its customers. The agreement also positions TELUS
for future development as Acision's advanced messaging solution is designed
to enable operators to scale easily and launch additional mobile data
services such as MMS, as well as innovative and personalized messaging
services.

"TELUS is seeing tremendous interest from its customers for new SMS
capabilities. In Acision, we have found a partner which offers a
best-in-breed next generation SMS architecture that addresses the
opportunities available to us today and positions us to deliver superior
services in the future," said Ken Kerrigan , vice-president of Network
Technology at TELUS. "In addition to a superior customer experience and
future-proof SMS messaging environment, this centrally-managed SMS platform
simplifies our current architecture and reduces our Total Cost of Ownership
significantly."

This advanced messaging capability is made possible by the deployment of
the Acision Short Message Service Center, a complete messaging solution and
core part of Acision's Data Services Architecture that can support TELUS'
entire messaging infrastructure. Acision will also deploy the Acision
Universal Gateway, which enables the introduction of new third-party
services, real-time event triggering and database look ups; the Acision
Central Management Station, a framework to monitor, measure and manage
messaging data services; and Acision Business Tools, which enables services
and key performance reporting, as well as web based customer care.

"The multi-year agreement with TELUS - a tier one carrier with 6.7
million wireless subscribers - is further evidence of Acision's commitment to
serve the Canadian market with profit generating mobile data solutions," said
Rory Buckley, Chief Executive of Acision. "TELUS' selection of Acision is
further validation of the high quality and value add of our data services
solutions and strategy. In addition, the agreement further extends Acision's
market share leadership position, both globally and within the North American
market."
