Item 5. Other Information

     On April 3, 2000, IDEX Corporation (the "Company") announced that Donald N.
Boyce, the Company's Chairman of the Board of Directors, retired on March 31,
2000. Mr. Boyce's decision to retire was consistent with his plan to remain on
the Board of Directors for one year following his retirement on March 31, 1999,
as chief executive officer. Mr. Boyce, 61, has been with the Company since its
founding in 1988. He served as chairman, president and chief executive officer
through 1997, and as chairman and chief executive officer through March 31,
1999.

     Frank J. Hansen, who was appointed president and director on January 1,
1998, and assumed the additional duties of chief executive officer on April 1,
1999, previously announced his intention to retire in November, 1999, but will
remain as president and chief executive officer until his replacement is
selected. In the interim, IDEX's board of directors will continue with eight
members. The search for the new president and chief executive officer, who will
also assume the additional role of chairman, is expected to conclude by the end
of April, 2000. Mr. Hansen will continue to provide leadership through this
transition.
