ITEM 5.    OTHER EVENTS AND REGULATION FD DISCLOSURE

           On April 22, 2004, IDEX Corporation issued a press release announcing
           a 3 for 2 Stock Split and an increase in its quarterly cash dividend
           of 29 percent. A copy of this press release is included below.


                 IDEX CORPORATION ANNOUNCES 3-FOR-2 STOCK SPLIT;
                  INCREASES QUARTERLY CASH DIVIDEND 29 PERCENT


           NORTHBROOK, IL, APRIL 22, 2004 - IDEX CORPORATION (NYSE: IEX) today
           announced that its Board of Directors has declared a 3-for-2 split of
           the company's common stock and approved a 29 percent increase in the
           quarterly cash dividend.

           The 3-for-2 stock split of IDEX common shares, which will be effected
           in the form of a 50 percent stock dividend, will be payable May 28,
           2004, to shareholders of record as of May 14, 2004. Shareholders will
           receive one additional share of IDEX common stock for every two
           shares that they own as of the record date. Any fractional shares
           resulting from the split will be paid in cash based on the closing
           market price of the common stock on the record date. This action
           reflects the third split of the company's common stock since its
           initial public offering in 1989.

           Separately, the Board of Directors has approved a 29 percent increase
           in the company's regular quarterly cash dividend to $0.18 per common
           share (or $0.12 per post-split share), payable July 30, 2004, to
           shareholders of record as of July 15, 2004.

           IDEX Chairman and Chief Executive Officer Dennis K. Williams said,
           "IDEX has an excellent track record and its prospects for the future
           remain bright. The dividend increase reflects the Board's confidence
           in the company's outlook as we continue to pursue our operational
           excellence and global growth initiatives. Our strong performance also
           has created the opportunity for a stock split which we believe, over
           time, will help enhance liquidity in the trading of IDEX shares for
           current and prospective shareholders."

           FORWARD-LOOKING STATEMENTS
           This news release contains forward-looking statements within the
           meaning of Section 27A of the Securities Act of 1933, as amended, and
           Section 21E of the Exchange Act of 1934, as amended. These statements
           may relate to, among other things, capital expenditures, cost
           reductions, cash flow, and operating improvements and are indicated
           by words or phrases such as "anticipate," "estimate," "plans,"
           "expects," "projects," "should," "will," "management believes," "the
           company believes," "the company intends," and similar words or
           phrases. These statements are subject to inherent uncertainties and
           risks that could cause actual results to differ materially from those
           anticipated at the date of this news release. The risks and
           uncertainties include, but are not limited to, the following:
           economic and political consequences resulting from terrorist attacks
           and wars; levels of industrial activity and economic conditions in
           the U.S. and other countries around the world; pricing pressures and
           other competitive factors, and levels of capital spending in certain
           industries - all of which could have a material impact on order rates
           and IDEX's results, particularly in light of the low levels of order
           backlogs it typically maintains; its ability to make acquisitions and
           to integrate and operate acquired businesses on a profitable basis;
           the relationship of the U.S. dollar to other currencies and its
           impact on pricing and cost competitiveness; political and economic
           conditions in foreign countries in which the company operates;
           interest rates; capacity utilization and the effect this has on

           developments with respect to contingencies, such as litigation and
           environmental matters. The forward-looking statements included here
