Item 1.01.  Entry into a Material Definitive Agreement.

On October 15, 2004, the Board of Directors of Concord Communications, Inc. (the
"Company") appointed Ted D. Williams to the position of Executive Vice
President, Worldwide Field Operations. The press release announcing the
appointment of Mr. Williams is attached hereto as Exhibit 99.1. In connection
with such appointment, Mr. Williams entered into a Management Change in Control
Agreement with the Company on October 15, 2004 (the "Change in Control
Agreement").

In connection with entering into the Change in Control Agreement, Mr. Williams
has entered into a non-competition agreement with the Company pursuant to which
he has agreed, following a change in control of the Company, not to compete with
the Company for a period of six months if he has been terminated with or without
cause by the Company or he has voluntarily terminated his employment for "good
reason."

Pursuant to the terms of the Change in Control Agreement, Mr. Williams is
entitled to receive a single severance payment in cash in an amount equal to six
months' base annual salary if he is terminated by the Company without cause or
he voluntarily terminates his employment with the Company for "good reason"
(each a "Termination Event"), in each case within six months of a change in
control of the Company. Effective upon a change in control of the Company, the
vesting date for Mr. Williams' unvested options shall be accelerated by a period
of twenty-four months. If within twenty-four months of a change in control of
the Company there is a Termination Event, Mr. Williams' remaining unvested
options will become fully vested.

The Change in Control Agreement also provides that Mr. Williams is guaranteed a
minimum quarterly bonus of $32,500 for each quarter of the 2005 calendar year.
In addition, if Mr. Williams is terminated without cause, the Company will pay
severance to Mr. Williams in a cash amount equal to twelve months base annual
salary.
