eHealth(TM) Suite Manages Infrastructure

for One of the Largest Financial Services Providers

in Canada and North America 

Concord Communications (Nasdaq: CCRD), today announced that Bank of Montreal, part of the BMO Financial Group (NYSE, TSX: BMO), has selected the eHealth Suite(TM) of infrastructure management software to proactively manage and monitor the bank's expansive network infrastructure.

BMO Financial Group is one of the largest financial services providers in North America, with average assets of $247 billion as of July 31, 2002. BMO's subsidiary, Bank of Montreal, leverages Concord's eHealth Suite to manage its corporate IT infrastructure as well as the infrastructure at BMO's subsidiaries, BMO Nesbitt Burns and Chicago-based Harris Bank.

Upon evaluation of three other leading infrastructure management software solutions, Bank of Montreal selected Concord's eHealth Suite based on the software's ability to support a complex IT infrastructure that spans corporate headquarters in Canada as well as the Bank's affiliates in other Canadian regions and in the United States. As the first Canadian bank to open branches abroad, Bank of Montreal has long been active in markets in Europe, Latin America, and East Asia as well as in the United States.

"With a network as large as ours, we needed to be sure that our end-to-end infrastructure management software solution would meet Bank of Montreal's complex IT requirements while protecting our technology investments," said Tom Curtis, network performance manager, Bank of Montreal. "When we evaluated competitive market offerings, we certainly put the leading infrastructure management solutions through their paces and Concord's eHealth Suite proved to be the best integrated fault and performance management software for Bank of Montreal's IT needs. The use of Concord's eHealth Suite continues to grow at Bank of Montreal and is a vital part of our corporate IT infrastructure."

Bank of Montreal's IT staff leverages the eHealth Suite to manage 18,000 elements, 1500 routers and a new IP network, as well as the traffic that is routed to corporate headquarters from BMO subsidiaries. Additionally, the eHealth Suite is used for performance management, reporting, and capacity planning to proactively avert network failures before they impact performance or jeopardize end-user satisfaction.

"As Concord continues to work alongside leading banks and financial institutions, we consistently hear the need for an integrated end-to-end fault and performance management solution that protects IT investments while strengthening relationships with customers, whether it be individual investors, brokerage firms, or commercial clients," said Brian Burba, vice president, market and partner development, Concord. "Bank of Montreal's selection of the eHealth Suite, upon evaluation of several leading offerings, confirms Concord's ability to provide the infrastructure management solution that is required by so many financial institutions today."
