           March Networks Launches New Managed Video Network Services
                          with 300+ Site Customer Win


March Networks(TM)  (TSX:MN; AIM:MNW), a leading provider of Internet Protocol
(IP)-based digital video surveillance solutions, announced today that it has
launched Managed Video Network Services as a complementary offering to its
extensive portfolio of digital video recorders (DVRs) and software. The
value-added service is designed to provide March Networks customers with an
additional level of video network reliability, as many of these deployed
networks have grown to exceed thousands of systems spanning multiple geographic
regions.

March Networks is initially making the service available to North American
customers and has signed its first Managed Video Network Services contract with
Sheetz, Inc., a convenience store chain based in Altoona, PA with more than 300
locations.

Managed Video Network Services provides organizations with a range of outsourced
health monitoring, diagnostics and troubleshooting options to maintain the
highest performance and availability from their entire IP video network.
Comprehensive monitoring and management of mission-critical video networks can
proactively identify and address technical issues, thereby preventing system
downtime and the potential loss of video information. By subscribing to Managed
Video Network Services, organizations can focus on their core operations,
confident that their video security systems are performing optimally and
cost-effectively.

Sheetz first deployed March Networks DVR systems in 2003 as part of a
comprehensive store security and operations management program. Video from the
DVRs has been used over the years to assist law enforcement with fraud
investigations, and is linked to a centralized monitoring center to enable
Sheetz security operations staff to respond quickly in emergency situations.
Sheetz decided to outsource the management of its DVR systems in 2005. Michelle
Sisto, store solutions manager with Sheetz states, "The whole focus of our
security operations is to ensure the safety of our employees and customers. With
March Networks' new service operating 24/7, it helps us meet that goal."

"The Managed Video Network Services offering is an important element of our core
strategy, focused on continuing to enhance our solutions and provide value-added
services to our customers," states Peter Strom, March Networks president and
CEO. "We anticipate that demand for Managed Video Network Services will increase
considerably in the coming months and years as our key customers continue to
deploy thousands of DVRs in mission-critical applications."
