July 21, 2004 (filed as Exhibit 10.1 to the Company's Quarterly Report filed on
Form 10-Q for the period ending September 30, 2004) pursuant to which Mr.

Officer. Mr. Kingsley's annual base salary was increased to $600,000 and a bonus

on a bonus of 100% of base salary. A copy of the First Amendment to Employment
Agreement is attached hereto as Exhibit 10.20(a).

Incentive Award Plan

      On February 2, 2005 the Board of Directors of the Company adopted the IDEX
Corporation Incentive Award Plan (the "Plan"), subject to approval of the
Company's stockholders. On March 22, 2005 the holders of a majority of the
issued and outstanding stock of the Company present in person or by proxy and
entitled to vote thereon approved adoption of the Plan. A copy of the Plan was
filed as Appendix A to the Proxy Statement, dated February 25, 2005 and filed
with the Securities and Exchange Commission on February 28, 2005, and is
incorporated herein by reference.

Option and Restricted Stock Grants

      On March 22, 2005, upon approval of the Plan by its stockholders, the
Company awarded nonqualified stock options with an exercise price of $40.35, the
closing price of the Company's common stock on the immediately preceding trading
day, which is the fair market value of the Company's common stock as determined
under the terms of the Plan, to the following executive officers and in the
following amounts:

                                              Number of Shares of Common
          Officer                              Stock Subject to Option
          -------                             --------------------------
          Lawrence D. Kingsley                          55,060
          Dominic A. Romeo                              12,500
          John L. McMurray                              10,000
          David T. Windmuller                            7,000

      Each of the options vest at a rate of 25% each year on the anniversary of
the date of grant and expire on March 22, 2015. However, if the executive's
employment terminates by reason of death, disability or retirement (age plus
service equals 70, with at least 5 years of service after attaining an age of at
least 50) then they will fully vest in their options. Options also fully vest
upon a change in control. To the extent then vested and subject to the term of
the option, each option may only be exercised for 90 days following the
recipient's final day of active employment with the Company, unless such
termination is by reason of death, disability or retirement. Upon termination
for death, disability or retirement, the option remains exercisable for up to
one year. Each option is not transferable except by will or by the laws of
descent or distribution. A copy of the form of Stock Option Agreement that the
Compensation Committee has approved for award of stock option grants under the
Plan is attached hereto as Exhibit 10.23.

          Officer                                   Restricted Stock
          -------                                  -------------------     
          Lawrence D. Kingsley                          17,810
          Dominic A. Romeo                               4,040
          John L. McMurray                               3,240
          David T. Windmuller                            2,260

      The restricted stock is not transferable and is subject to forfeiture in
the event the recipient terminates employment for reasons other than death,
disability or retirement prior to March 22, 2009. A recipient will be vested in
the stock if they terminate



employment by reason of death, disability or retirement prior to March 22, 2009.

reason of death, disability or retirement. A copy of Mr. Kingsley's Restricted
Stock Agreement is attached hereto as Exhibit 10.25.

performance award under the terms of the Plan, pursuant to which Mr. Kingsley is
eligible to receive a cash bonus based upon attainment of performance goals
relating to operating income in 2005. The maximum bonus that Mr. Kingsley may
receive under the terms of the performance award is 2% of the Company's
