           On May 24, 2004, IDEX Corporation issued a press release announcing

                 IDEX CORPORATION COMPLETES ACQUISITION OF SCIVEX, INC.;
                      STRATEGIC EXPANSION OF LIFE SCIENCES BUSINESS


           NORTHBROOK, IL, MAY 24, 2004 -- IDEX CORPORATION (NYSE: IEX) today
           announced the completion of its previously-announced acquisition of
           Scivex, Inc., a leading provider of fluidic components and systems
           for the analytical, biotechnology and diagnostic instrumentation
           markets. Scivex, which represents a strategic expansion of IDEX's
           life sciences business, will be operated as a standalone business as
           part of the IDEX Pump Products Group. Scivex was previously owned by
           KRG Capital Partners, a middle market private equity firm based in
           Denver, Colorado. Terms of the cash transaction were not DISCLOSED.

           Scivex operates Upchurch Scientific in Oak Harbor, Washington;
           Sapphire Engineering in Pocasset, Massachusetts; and J.L. White in
           Santa Clara, California, and has annual sales of approximately $31
           million. Scivex is a leading developer, manufacturer and marketer of
           highly-engineered, cost-effective fluidic solutions for the
           analytical, biotechnology, clinical diagnostic and related life
           sciences market.

           Commenting on the acquisition, IDEX Chairman and Chief Executive
           Officer Dennis K. Williams said, "Scivex fits IDEX's growth strategy
           exceptionally well and is an excellent addition to our company. The
           combination of Micropump, Ismatec, Trebor, Rheodyne, Systec and
           Scivex will significantly enhance our ability to meet our customers'
           needs in the growing, global market for analytical, biotechnology,
           medical and diagnostic instrumentation solutions."

           Alan Schell, chief executive officer of Scivex, Inc., said, "We are
           excited to become part of IDEX, a world leader in fluid-handling
           technologies. Together, our companies are well positioned to meet the
           global demand for high-value, cost-effective fluidic components and
           sub-assemblies used in the analytical, biotechnology, clinical
           diagnostic and related life sciences markets."
