Item 5. Other Information

On September 10, 2001, IDEX Corporation announced that it expects earnings per
diluted share for the third quarter of 2001 to be in the range of 25 to 30
cents. In the same period last year, IDEX earned 54 cents; in the second quarter
of this year, the Company earned 42 cents; and in the first quarter, earnings
were 35 cents before restructuring charges. The decline in profits is primarily
attributable to weaker-than-expected business conditions in the U.S. and some
international markets.

The Company's July 17, 2001 earnings guidance for the third quarter was based on
the expectation that orders and sales levels would remain at the rate achieved
in the first half of the year. Unfortunately, this has not occurred. Orders
received in July were the lowest this year. While August orders increased
somewhat, they still were below the first-half average. As a result, it is
highly unlikely that the full third quarter will match the first or second
quarter's orders and sales, let alone the performance seen at this time last
year. These expected declines are primarily associated with the continuing
weakness in North America and declines in European business activity. While IDEX
has seen softness in virtually all end-markets, the most significant impact has
been felt at the Company's pump and dispensing equipment business units that
serve the paints and coatings, general industrial, automotive and chemical
processing markets. These are the same problems that many of IDEX's peers and
customers are facing. However, two positive points are worth noting. First, the
Asian market remains strong and is growing, and second, the Company's management
believes IDEX is maintaining its market shares.

The Company's fourth quarter performance will depend on the pace of incoming
business over the next few months. IDEX operates with a very small backlog of
unfilled orders, and it is not able to assess how long the current softness in
the Company's markets will last.

The Company's management believes IDEX is well positioned for a strong recovery
once economic conditions improve. This is based on the Company's reduced cost
structure; margin improvement initiatives of Six Sigma, global sourcing and
eBusiness; and also the use of strong cash flow to cut debt and interest
expense. In addition, IDEX continues to pursue acquisitions to drive the
company's longer-term profitable growth.
