ITEM 5. OTHER EVENTS

        On July 22, 2004, IDEX Corporation issued a press release announcing the
        appointment of Lawrence D. Kingsley as Chief Operating Officer. A copy
        of this press release is included below.


                 IDEX CORPORATION APPOINTS LAWRENCE D. KINGSLEY
                           AS CHIEF OPERATING OFFICER


NORTHBROOK, IL, JULY 22 - IDEX CORPORATION (NYSE: IEX), the world leader in
fluid-handling technologies for positive displacement pumps, dispensing
equipment for color formulation, and other highly engineered products including
fire suppression and rescue tools, today announced the appointment of Lawrence
D. (Larry) Kingsley to the newly created position of chief operating officer.
Kingsley most recently served as corporate vice president and group executive
for the Industrial Controls Group at Danaher Corporation.

Reporting to the company's Chairman, President and Chief Executive Officer
Dennis K. Williams, Kingsley will be responsible for assisting in the
development and execution of corporate strategy and driving the financial and
operating performance of IDEX's three global business groups in pumps,
dispensing equipment, and engineered products.

Prior to joining IDEX, Kingsley progressed through a series of increasingly
responsible operating positions at Danaher Corporation, including corporate vice
president and group executive for the combined industrial controls and sensors
businesses; president of the industrial controls group; and president, motion
group - special purpose systems. Prior to Danaher, Kingsley held several
positions of increasing responsibility with Kollmorgen Corporation, including
vice president and general manager for European operations of the industrial and
commercial products division. Prior to Kollmorgen, Kingsley was vice president
marketing and sales for Weidmuller Incorporated, a subsidiary of C.A.
Weidmuller, GmbH. He holds an undergraduate degree in industrial engineering
with a mechanical engineering concentration from Clarkson University and an MBA
from the College of William and Mary.

Commenting on the appointment, Williams said, "We are delighted to welcome an
executive of Larry's caliber to the IDEX team. He brings to our company
impressive operating experience and global leadership capability. Larry will
work closely with me and the senior leadership of our organization to continue
to drive our best-in-class operational practices, while further developing and
leveraging the strategic and operational synergies of our growing and
increasingly global business platform. Larry's appointment is also part of the
succession planning for the company."

The Board of Directors and Mr. Williams are committed to achieving an orderly
succession of the CEO position at an appropriate time in the future. Mr.
Williams has committed to remain with the company beyond the May 2005 expiration
of his current contract to assure a smooth transition with his eventual
successor. While no related commitment has been made to Mr. Kingsley at this
point in time, he would, of course, be considered for the CEO position.
