    CHICAGO, LONDON and SINGAPORE, Jan. 8 /PRNewswire-FirstCall/ -- The Board
of Directors of Jones Lang LaSalle Incorporated (NYSE: JLL) announced today
that it has accepted with regret the resignation of Christopher A. Peacock as
President and Chief Executive Officer. At Mr. Peacock's request, his
employment resignation takes effect immediately, and he has also retired from
the Board of Directors at this time.  Stuart L. Scott, Chairman of the Board

until a permanent replacement is named.  Mr. Peacock's resignation is based on
his personal decision to spend more time with his family. Although total year
results are not yet complete, the firm is making no adjustment to its 2003

a new CEO, members of the firm's Global Executive Committee will report

are the company's regional CEOs for Asia Pacific, Europe and the Americas,
respectively; Lynn Thurber, CEO of LaSalle Investment Management; and Lauralee
Martin, the company's Chief Financial Officer.

Chris for his more than 30 years of committed service to the firm," said Mr.
Scott.  "His dedication to superior client service has played a significant
role in establishing Jones Lang LaSalle as the leader in delivering
comprehensive real estate services across the globe. I am pleased that Chris
will serve the company on a consultative basis for the immediate future."
    Mr. Scott continued, "We are beginning our search for a new CEO
immediately and, while we expect to move quickly, we will take whatever time
is required to select the best person to lead our company. I want to emphasize
that, during this time, we will not be distracted from our commitment to the
highest standards of client service, and to our employees and shareholders."

2002.  He was CEO of LaSalle Partners from 1990 until the merger with Jones
Lang Wootton in 1999.  Mr. Peacock held the position of Chief Operating
