OTTAWA and WATERLOO, CANADA, September 29, 2010 - Bridgewater Systems (TSX: BWC), the mobile personalization company, and
Sandvine (TSX:SVC; AIM:SAND) a leading provider of network policy control
solutions for fixed and mobile operators, today announced that the two
companies have successfully completed integration and interoperability
testing enabling intelligent policy control solutions for 3G and 4G mobile
operators.

News

    - Sandvine and Bridgewater have successfully completed
      interoperability of Sandvine's Policy Traffic Switch (
      www.sandvine.com/products/policy_traffic_switch.asp) (PTS) which
      detects network conditions, counts usage and enforces network and
      subscriber policy decisions defined by the Bridgewater(R) Policy
      Controller (PCRF) (
      www.bridgewatersystems.com/Policy-Controller.aspx) to manage
      mobile data growth and deliver new services. The testing included the
      PCRF Gx and Gy usage metering interfaces for 3GPP-compliant Policy
      Control Enforcement Points.

    - The interoperability testing showcases the two companies' commitment to
      delivering 3G and 4G policy control solutions that are standards
      compliant and address next generation services requirements for mobile
      operators.

    - The joint policy solutions enable mobile operators to:

    - Deliver tiered services by applying policies that, for example, give
      Bronze subscribers 500 megabytes per month of data, with no peer-to-
      peer services or parental controls, while providing Gold subscribers
      with one gigabyte per month of data including peer-to-peer services and
      parental controls.

    - Personalize applications usage by applying policies such as allowing
      unlimited social networking for a fixed monthly fee and offering usage
      restrictions during school hours.

    - Ensure fair usage by applying policies based on subscriber service
      plans and real-time network congestion levels.

    - The joint Sandvine and Bridgewater solution is live today in a major
      North American 4G operator network and the two companies are working
      Together on joint opportunities globally.
