The investment in additional infrastructure is in response to strong customer demand and underlines Atrium Network's continued success in providing unparalleled access to the vibrant Canadian markets. Atrium Network's low latency network offers access to all of the cash equities markets in Toronto and also provides access to multiple other trading counterparties throughout the Americas and into Europe.

Trading participants using Atrium Network's infrastructure have been able to connect and take advantage of access to the firm's ever-increasing community of buy-side, sell-side, market data providers and industry vendors.

Commenting on the expansion at the 151 Front Street location, Emmanuel Pellé, chief operating officer of Atrium Network said, "Atrium Network's strategy has been to offer clients full access to all of the Canadian Markets. The success of this strategy has now been verified with the recent announcement of connectivity to TMX Group giving Atrium Network customers low latency access TSX/MX market data and access to TMX Group's equity and derivatives markets. Not only are we witnessing a continued drive for market data feeds from our Toronto customers but we are also seeing Toronto based clients access the US markets located in Chicago and New York/New Jersey."

Emmanuel Carjat, chief executive officer added, "We're delighted that demand for access to Atrium Network continues to grow and as such our global network is becoming ever more populated with valuable trading participants. We are always exploring new routes and new paths between Toronto and the major markets in New Jersey and New York and throughout 2011 will continue to upgrade our infrastructure in line with customer demand and extend our network capabilities within key financial centres."
