ITEM 2.03.    CREATION OF A DIRECT FINANCIAL OBLIGATION OR AN OBLIGATION UNDER 
              OFF-BALANCE SHEET ARRANGEMENTS.

On December 15, 2004, IDEX Corporation announced that it closed a new five-year,
$600 million senior revolving credit facility.

The facility was financed through a syndication of 17 financial institutions,
co-led by Banc of America Securities LLC and Wachovia Capital Markets LLC, with
ABN AMRO Bank, N.V., Mizuho Corporate Bank, Ltd. and U.S. Bank National
Association acting as co-agents.

The increased credit facility was timed to capitalize on current, favorable
market conditions and replaces the company's previous $300 million credit
facility, which had been due to expire on June 8, 2006.

Also on this date, the company renewed its Receivables Purchase Agreement for
another year. The agreement provides for borrowings of up to $25 million
depending upon the level of eligible receivables.
