$30,000,000                                        November 22, 2002

     For value received, IDEX Corporation, a Delaware corporation ("Borrower"),
promises to pay to the order of Credit Lyonnais New York Branch ("Lender") the
lesser of (a) Thirty Million United States Dollars ($30,000,000) and (b) the
aggregate unpaid principal amount of the Loans made by Lender to Borrower
pursuant to the Offer (as hereinafter defined) on the dates provided for
therein. Borrower promises to pay interest on the unpaid principal amount of
each such Loan on the dates and at the rate or rates provided for in the Offer.
All such payments of principal and interest shall be made in lawful money of the
United States in Federal or other immediately available funds at the office of
Credit Lyonnais New York Branch, 1301 Avenue of the Americas, New York, NY
10019.

     All Loans made by Lender, the respective types and maturities thereof and
all repayments of the principal thereof shall be recorded by Lender and, if
Lender so elects in connection with any transfer or enforcement hereof,
appropriate notations to evidence the foregoing information with respect to each
such Loan then outstanding may be endorsed by Lender in the schedule attached
hereto or on a continuation of such schedule attached to and made a part hereof;
PROVIDED, HOWEVER, that the failure of Lender to make any such recordation or
endorsement shall not affect the obligation of Borrower hereunder or under the
Offer.

     This note is the Note referred to in the Offer, dated as of December 3,
2001, between Borrower and Lender (as amended, and as the same may be amended,
supplemented or otherwise modified from time to time, the "OFFER"). Terms
defined in the Offer are used herein with the same meanings. Reference is made
to the provisions of the Offer for, among other things, prepayment of the Loans
and the acceleration of the maturity thereof.

     This Note is issued in substitution for, but not in repayment of, the Note
dated December 3, 2001. Any Loans outstanding under such prior Note shall
constitute loans under, evidenced by and subject to the terms of this Note.

         This Note shall be governed by and construed in accordance with the
laws of the State of New York.
