IPC and Internet Solutions Partner to Deliver Direct Trading Connectivity Between Global Financial Centers

Strategic Partnership Delivers Instantaneous and Resilient Trader Communications across South Africa, Europe, United States and Asia Pacific

JERSEY CITY, New Jersey, March 1, 2010 - IPC Systems, a leading provider of indispensable trading communications
solutions to the world's leading financial services firms and global
enterprises, today announced that it has expanded its global network coverage
through a partnership with Internet Solutions (IS), a division of Dimension
Data, based in South Africa. This partnership dramatically reduces the
installation time to connect with trading venues across Europe and Africa,
whilst assuring optimal service levels required to complete international
trading transactions. Today's news follows IPC's recent announcement
(www.ipc.com/repository/document/411.pdf) of the expansion of its
services in Asia Pacific and demonstrates commitment to partnering with
best-of-breed companies to deliver access to IPC's global network.

IPC partnered with IS, a leading converged communications service
provider offering an innovative portfolio of voice and data services within
South Africa. The partnership enables IPC's customers to take advantage of
its network reach supported by the expertise of IS to deliver its services
effectively and reliably to financial services firms based in Africa.

South Africa is primed for connection to major international capital
markets due to the strength of its bond market. This enables IPC's On-Net
community, comprising nearly 4,000 locations, to connect more rapidly to
trading partners in Cape Town and Johannesburg, across a resilient and
diverse network dedicated to traders. The presence in South Africa and the
relationship with IS increases IPC's global network reach and provides direct
connectivity to a rapidly developing financial center.

"IPC continually invests in its global network to provide access to new
pools of liquidity. This ensures that we are able to connect our customers to
more markets quickly, securely and reliably," said Mathew Whitmore, program
manager, Network Services, IPC Systems. "Our partnership with Internet
Solutions is another important step in supporting global financial services
firms to compete effectively in the modern marketplace."

The connectivity in South Africa provides an ultra-resilient secure
global financial network supported by IPC's unmatched, always-on, proactive
service management to facilitate high performance trading on a global scale.

"Internet Solutions is proud to have been chosen for the provision,
management and uptime support for IPC's South African footprint," said Wayne
Speechly, general manager, Voice Solutions, Internet Solutions. "Driven by
our experience and in-depth knowledge of the local market both from a
technical and regulatory perspective, our services enforce IPC's network
capabilities securely and reliably within this region."
