    MARLBORO, Mass.--(BUSINESS WIRE)--Oct. 20, 2004--

  New Executive Vice President Brings Strong Operational, Sales, and
     Customer Relationship Credentials to Existing Management Team

    Concord Communications, Inc. (Nasdaq: CCRD), a global provider of
Business Service Management (BSM) software solutions, today announced
that it has named Ted Williams as its new Executive Vice President of
Worldwide Field Operations. Over the past 25 years, Williams has been
instrumental in creating strong market demand and generating
consistent revenue growth for enterprise software companies. At
Concord, Williams will direct the company's global sales force, manage
its international reseller network, and oversee its professional
services team.
    "Ted's exceptional track record, strong customer relationships,
and thorough grasp of the enterprise software market were key factors
in his selection for this role," stated Jack Blaeser, president and
CEO of Concord Communications. "His systematic approach to selling,
his experience with large and complex deals, and his total commitment
to customer success and satisfaction all align directly with our
corporate philosophy. I am confident that Ted will be instrumental in
leading our sales organization to new levels of productivity and
achievement."
    Prior to joining Concord, Williams was executive vice president of
worldwide sales for MRO Software, a strategic asset management
software provider, where he directed a global team of more than 175
sales professionals and alliance managers. A ten-year veteran of MRO
Software's sales team, Williams substantially contributed to that
company's impressive revenue growth of more than 700 percent since the
early 1990s. Williams' ability to develop measurable, repeatable
processes that leverage a combination of sales best practices and
supporting technologies allowed him to consistently succeed against
the competition. Once sold, customers also remained a priority for
Williams, enabling him to assemble a deep executive-level network
within the Global 1000. Williams' network and operational leadership
experience will prove strong assets for Concord.
    Commenting on his appointment, Ted Williams remarked, "Concord
appears to be uniquely qualified to address a growing market
opportunity. I am confident in the company's ability to execute on
that opportunity and I am excited to bring a fresh perspective and new
energy to the task. I look forward to leveraging my experience in
managing multiple sales channels and my strong ties with systems
integrators to contribute to Concord's future success."
    Earlier in his career at MRO Software, Williams served as director
of industry marketing and managed the company's MAXIMO product line.
Prior to MRO Software, Williams held project management roles at two
world-leading engineering/construction companies, Fluor Corporation
and Stone & Webster Engineering Corporation. He also served as
president and COO of Comac Systems Corporation, an enterprise software
startup. Williams earned his M.B.A. from San Francisco State
University, and his engineering degree from Northeastern University.
He has taught management classes at Boston University and Emmanuel
College.
