Vivox™ And BigWorld Pty Ltd Announce Partnership

Framingham, Mass. - September 5, 2006 - Vivox Inc., a leader in integrated online voice communications, today announced a joint marketing agreement with BigWorld Pty. Ltd. and the inclusion of the Vivox Precision Studio integrated voice solution into the BigWorld Technology Suite.

The BigWorld Technology Suite provides operators and studios with a lower total time-to-release and cost of ownership through several innovations. The BigWorld Server architecture allows operators to run several games on a single server cluster, dramatically reducing the cost of running the game, while the enhanced content creation pipeline reduces the time and cost of building and filling out the complex worlds required in next-generation games.

With its carrier-grade managed service, Vivox empowers game developers to integrate communications that allows players to communicate dynamically in groups or privately one-on-one within the game. Unlike third-party applications, Vivox communication services are fully integrated into the game. As a result, all players can communicate clearly and naturally - talking, strategizing, plotting and negotiating with each other with no impact on game server performance. Vivox empowers game developers to open communication capabilities to their entire player base without limitation or concern. Real-time communications are integrated, clear, and massively scalable. And because all communication is done through the Vivox Network, there is no impact on the game servers and minimal drain to CPU resources.

"BigWorld is the leading provider of advanced development solutions for game designers and producers," said Rob Seaver, CEO of Vivox. "BigWorld's selection of Vivox's integrated voice communications is a clear example of their ongoing commitment to delivering the best possible features and solutions to their customers. Finally, developers will be able to include a voice solution in their games that is deeply integrated, massively scalable and supported by a team of communications experts. We're excited to be working with BigWorld and their customers to support their development of visionary new games."

BigWorld Technology Suite is an integrated set of tools, software and systems that provides all of the underlying technology and content development tools required to produce an MMOG. "There is no doubt that the next-generation of online games includes voice," commented John De Margheriti, CEO, BigWorld Pty Ltd. "By partnering with Vivox we can now offer the scalability service to our developers that they require to expand their game worlds and player base."

Vivox and BigWorld will be co-exhibiting at the Austin Games Conference, September 6-8, 2006 in Austin, Texas. The integrated solution will be demonstrated in the Vivox booth number 314 and the BigWorld booth number 502.
