Item 2.03 - Creation of a Direct Financial Obligation or an Obligation Under
Off-Balance Sheet Arrangements.

On December 22, 2006, IDEX Corporation announced that it closed an amended and
restated five-year, $600 million senior revolving credit facility. The facility
was financed through a syndication of 15 financial institutions, co-led by Banc
of America Securities LLC and Wachovia Capital Markets LLC, with LaSalle Bank,
N.V., Mizuho Corporate Bank, Ltd., and The Bank of Tokyo-Mitsubishi UFJ, Ltd.,
acting as co-documentation agents.

The amended credit facility was timed to capitalize on current, favorable market
conditions and replaces the company's previous $600 million credit facility,
which had been due to expire on December 14, 2009.

A copy of the Amended and Restated Credit Agreement is filed as Exhibit 10.1 to
this current report on Form 8-K and is incorporated herein by reference.
