PART I ITEM 1. BUSINESS. IDEX Corporation ("IDEX" or the "Company") manufactures an extensive array of engineered industrial products sold to customers in a variety of industries around the world. We believe that each of our business units is a leader in its niche market. We also believe that our consistent financial performance has been attributable to the manufacture of quality products designed and engineered by us, coupled with our ability to identify and successfully consummate and integrate strategic acquisitions. IDEX consists of three reportable business segments: Pump Products Group, Dispensing Equipment Group, and Other Engineered Products Group.

(with respect to fluid injectors and valves). The principal competitors of the Dispensing Equipment Group are Corob S.p.A. (with respect to dispensing and mixing equipment for the paint industry) and Lincoln Industrial (with respect to centralized lubrication systems). The Other Engineered Products Group's principal competitors are A.J. Gerrard & Company, a division of Illinois Tool Works Inc. (with respect to stainless steel bands, buckles and tools) and Waterous Company, a division of American Cast Iron Pipe Company (with respect to truck-mounted firefighting pumps). EMPLOYEES At December 31, 2005, IDEX had approximately 4,300 employees. Approximately 11% were represented by labor unions with various contracts expiring through November 2008. Management believes that the Company's relationship with its employees is good. The Company has historically been able to satisfactorily renegotiate its collective bargaining agreements, with its last work stoppage in March 1993. SUPPLIERS IDEX manufactures many of the parts and components used in its products. Substantially all materials, parts and components purchased by IDEX are available from multiple sources. INVENTORY AND BACKLOG The Company regularly and systematically adjusts production schedules and quantities based on the flow of incoming orders. Backlogs are therefore typically limited to approximately 1 to 1 1/2 months of production. While total inventory levels may also be affected by changes in orders, the Company generally tries to maintain relatively stable inventory levels based on its assessment of the requirements of the various industries served. 4

ITEM 1A. RISK FACTORS. For an enterprise as diverse and complex as the Company, a wide range of factors could materially affect future developments and performance. In addition to the factors affecting specific business operations identified in connection with the description of these operations and the financial results of these operations elsewhere in this report, the most significant factors affecting our operations include the following: CHANGES IN U.S. OR INTERNATIONAL ECONOMIC CONDITIONS COULD ADVERSELY AFFECT THE PROFITABILITY OF ANY OF OUR BUSINESSES. In 2005, 57% of the Company's revenue was derived from domestic operations while 43% was international. The Company's largest markets include paint and coatings, fire and rescue, machinery, life sciences and medical, chemical processing and petroleum-LPG. A slowdown in the economy and specifically any of these specific end markets could directly affect the Company's revenue stream and profitability. POLITICAL CONDITIONS IN FOREIGN COUNTRIES IN WHICH WE OPERATE COULD ADVERSELY AFFECT US. In the year ended December 31, 2005, approximately 43% of our total sales were to customers outside the U.S. We expect international operations and export sales to continue to contribute to earnings for the foreseeable future. Both the sales from international operations and export sales are subject in varying degrees to risks inherent in doing business outside the United States. Such risks include the following: - possibility of unfavorable circumstances arising from host country laws or regulations; - risks of economic instability; - currency exchange rate fluctuations and restrictions on currency repatriation; - potential negative consequences from changes to taxation policies; - the disruption of operations from labor and political disturbances; - changes in tariff and trade barriers and import or export licensing requirements; - insurrection or war We cannot assure you of the impact on us if such events occur in the future. INNOVATION IS A BIG DRIVER OF OUR REVENUE GROWTH. AN INABILITY TO CONTINUE TO DEVELOP NEW PRODUCTS CAN LIMIT THE COMPANY'S REVENUE AND PROFITABILITY. The Company's organic growth in 2005 and 2004 was 10% and 7%, respectively. More than 20% of our revenue was derived from new products developed over the past three years. Our ability to continue to grow organically is tied to our ability to continue to develop new products. OUR GROWTH STRATEGY INCLUDES ACQUISITIONS AND WE MAY NOT BE ABLE TO MAKE ACQUISITIONS OF SUITABLE CANDIDATES OR INTEGRATE ACQUISITIONS SUCCESSFULLY. Our historical growth has also depended, and our future growth is likely to continue to depend, in large part on our acquisition strategy and the successful integration of acquired businesses into our existing operations. We intend to continue to seek additional acquisition opportunities both to expand into new markets and to enhance our position in existing markets throughout the world. We cannot assure you, 6

however, that we will be able to successfully identify suitable candidates, negotiate appropriate acquisition terms, obtain financing which may be needed to consummate such acquisitions, complete proposed acquisitions, successfully integrate acquired businesses into our existing operations or expand into new markets. In addition, we cannot assure you that any acquisition, once successfully integrated, will perform as planned, be accretive to earnings, or prove to be beneficial to our operations and cash flow. Acquisitions involve numerous risks, including difficulties in the assimilation of the operations, technologies, services and products of the acquired companies and the diversion of management's attention from other business concerns. In addition, prior acquisitions have resulted, and future acquisitions could result, in the incurrence of substantial additional indebtedness and other expenses. Once integrated, acquired operations may not achieve levels of revenues, profitability or productivity comparable with those achieved by our existing operations, or otherwise perform as expected. THE MARKETS WE SERVE ARE HIGHLY COMPETITIVE. THIS COMPETITION COULD LIMIT THE VOLUME OF PRODUCTS THAT WE SELL AND REDUCE OUR OPERATING MARGINS. Most of our products are sold in competitive markets. We believe that the principal points of competition in our markets are product quality, price, design and engineering capabilities, product development, conformity to customer specifications, quality of post-sale support, timeliness of delivery, and effectiveness of our distribution channels. Maintaining and improving our competitive position will require continued investment by us in manufacturing, engineering, quality standards, marketing, customer service and support, and our distribution networks. We cannot assure you that we will be successful in maintaining our competitive position. Our competitors may develop products that are superior to our products, or may develop methods of more efficiently and effectively providing products and services or may adapt more quickly than us to new technologies or evolving customer requirements. Pricing pressures could also cause us to adjust the prices of certain of our products to stay competitive. We cannot assure you that we will be able to compete successfully with our existing competitors or with new competitors. Failure to continue competing successfully could adversely affect our business, financial condition and results of operations. WE ARE DEPENDENT ON THE AVAILABILITY OF RAW MATERIALS AND PARTS AND COMPONENTS USED IN OUR PRODUCTS. While we manufacture many of the parts and components used in our products, we require substantial amounts of raw materials and purchase some parts and components from suppliers. The availability and prices from materials and parts and components may be subject to curtailment or change due to, among other things, suppliers' allocations to other purchasers, interruptions in production by suppliers, changes in exchange rates and prevailing price levels. Any change in the supply of, or price for, these raw materials or parts and components could materially affect our business, financial condition and results of operations. SIGNIFICANT MOVEMENTS IN FOREIGN CURRENCY EXCHANGE RATES MAY HARM OUR FINANCIAL RESULTS. We are exposed to fluctuations in foreign currency exchange rates, particularly with respect to the euro and the British pound. Any significant change in the value of the currencies of the countries in which we do business against the U.S. dollar could affect our ability to sell products competitively and control our cost structure, which could have a material adverse effect on our business, financial condition and results of operations. The impact from these foreign currency exchange rate fluctuations is, to a certain extent, lessoned through invoicing our customers in the same currency as the source of the products. For additional detail related to this risk, see Item 7A. Quantitative and Qualitative Disclosure About Market Risk. AN UNFAVORABLE OUTCOME WITH REGARDS TO ANY OF OUR PENDING CONTINGENCIES OR LITIGATION COULD ADVERSELY AFFECT OUR BUSINESS, FINANCIAL CONDITION AND RESULTS OF OPERATIONS. We are currently involved in certain legal and regulatory proceedings and, as required and where it is reasonably possible to do so, have accrued our estimates of the probable costs for the resolution of these matters. These estimates have been developed in consultation with outside counsel and are based upon an analysis of potential results, assuming a combination of litigation and settlement strategies. It is possible, however, that future operating results for any particular quarter or annual period could be materially affected by changes in our assumptions or the effectiveness of our strategies related to these proceedings. 7

WE COULD BE ADVERSELY AFFECTED BY RAPID CHANGES IN INTEREST RATES. Our profitability may also be adversely affected during any period of unexpected or rapid increase in interest rates. At December 31, 2005, we had $160.0 million of total debt outstanding, of which approximately 6% was priced at interest rates that float with the market. A 50 basis point increase in the interest rate on the floating rate debt would result in an approximate $50,200 annualized increase in interest expense and decrease in cash flows. Historically, we have maintained a higher level of debt on our balance sheet. A higher level of debt would obviously increase the exposure discussed above. For additional detail related to this risk, see Item 7A. Quantitative and Qualitative Disclosure About Market Risk. OUR INTANGIBLE ASSETS ARE A SIGNIFICANT PORTION OF OUR TOTAL ASSETS AND A WRITE-OFF OF OUR INTANGIBLE ASSETS COULD CAUSE A MAJOR IMPACT ON THE COMPANY'S NET WORTH. Our total assets reflect substantial intangible assets, primarily goodwill. At December 31, 2005, goodwill totaled $691.9 million. The goodwill results from our acquisitions, representing the excess of cost over the fair value of the tangible assets we have acquired. At each balance sheet date, we assess whether there has been an impairment in the value of our intangible assets. If future operating performance at one or more of our business units were to fall significantly below current levels, we could reflect, under current applicable accounting rules, a non-cash charge to operating earnings for goodwill impairment. Any determination requiring the write-off of a significant portion of unamortized intangible assets would negatively affect our results of operations and total capitalization, which effect could be material. As of December 31, 2005, we have determined that no impairment existed. OUR BUSINESS COULD SUFFER IF WE ARE UNSUCCESSFUL IN NEGOTIATING NEW COLLECTIVE BARGAINING AGREEMENTS. As of December 31, 2005, we had approximately 4,300 employees. Approximately 11% of our employees are represented by unions with various contracts expiring through November 2008. We cannot assure you that we will be successful in negotiating new collective bargaining agreements, or that such negotiations will not result in significant increases in the cost of labor or that a breakdown in such negotiations will not result in the disruption of our operations. In addition, our closures of certain facilities may create the risk of strikes or work stoppages at those and other facilities. ITEM 1B. UNRESOLVED STAFF COMMENTS. The Company has received no written comments regarding its periodic or current reports from the staff of the Securities and Exchange Commission that were issued 180 days or more preceding the end of its 2005 calendar year and that remain unresolved. ITEM 2. PROPERTIES. The Company's principal plants and offices have an aggregate floor space area of approximately 3.2 million square feet, of which 2.2 million square feet (70%) are located in the U.S. and approximately 1.0 million square feet (30%) are located outside the U.S., primarily in Italy (7%), the U.K. (6%), Germany (6%) and The Netherlands (4%). These facilities are considered to be suitable and adequate for their operations. Management believes that utilization of manufacturing capacity ranges from 40% to 70% in each facility. The Company's executive office occupies approximately 26,000 square feet of leased space in Northbrook, Illinois. Approximately 2.3 million square feet (73%) of the principal plant and office floor area is owned by the Company, and the balance is held under lease. Approximately 1.8 million square feet (56%) of the principal plant and office floor area is held by business units in the Pump Products Group; 0.6 million square feet (19%) is held by business units in the Dispensing Equipment Group; and 0.7 million square feet (21%) is held by business units in the Other Engineered Products Group. 8

ITEM 3. LEGAL PROCEEDINGS. IDEX and five of its subsidiaries have been named as defendants in a number of lawsuits claiming various asbestos-related personal injuries, allegedly as a result of exposure to products manufactured with components that contained asbestos. Such components were acquired from third party suppliers, and were not manufactured by any of the subsidiaries. To date, all of the Company's settlements and legal costs, except for costs of coordination, administration, insurance investigation and a portion of defense costs, have been covered in full by insurance subject to applicable deductibles. However, the Company cannot predict whether and to what extent insurance will be available to continue to cover such settlements and legal costs, or how insurers may respond to claims that are tendered to them. Claims have been filed in Alabama, California, Connecticut, Delaware, Georgia, Illinois, Louisiana, Maryland, Michigan, Minnesota, Mississippi, Missouri, Nevada, New Jersey, New York, Ohio, Oregon, Pennsylvania, Texas, Utah, Washington and Wyoming. Most of the claims resolved to date have been dismissed without payment. The balance have been settled for reasonable amounts. Only one case has been tried, resulting in a verdict for the Company's business unit. No provision has been made in the financial statements of the Company, other than for insurance deductibles in the ordinary course, and IDEX does not currently believe the asbestos-related claims will have a material adverse effect on the Company's business or financial position. IDEX is also party to various other legal proceedings arising in the ordinary course of business, none of which is expected to have a material adverse effect on its business, financial condition or results of operations.

EXHIBIT 10.25 Frank J. Hansen / President and Chief Executive Officer (IDEX CORPORATION LOGO) IDEX CORPORATION 630 Dundee Road Northbrook, IL 60062-2745 (847) 498-7070 April 24, 2000 PERSONAL AND CONFIDENTIAL Mr. Frank J. Notaro 1133 North Dearborn, Apt. 2006 Chicago, Illinois 60610 Dear Frank: Re: Severance Agreement This is to confirm that in the event of your Termination from Service, as hereafter defined, with IDEX Corporation or its successors ("IDEX"), within twenty-four (24) months following, or, directly or indirectly, in connection with, or in anticipation of, a Change of Control, as hereinafter defined, you will be entitled to the following benefits as a severance payment (hereinafter referred to individually as a "Severance Benefit" and collectively as "Severance Benefits"): 1) Payment of your base salary and vacation pay (for vacation not taken, including vacation carryover from the prior year plus a pro rata accrual for the current year) accrued but unpaid through the date of termination of employment payable in a single lump sum payment on the last day employed or as soon thereafter as practicable. 2) Any amount earned under the Management Incentive Compensation Plan ("MICP") for the calendar year preceding the year in which the termination of employment occurs which has not been paid will be paid in a single lump sum payment on the last day employed or as soon thereafter as practicable. 3) An amount equal to three times the sum of (a) your annual base salary, at the rate in effect on the Determination Date, as hereinafter defined, and (b) your full year's bonus under the MICP at your Target Incentive Amount in effect on the Determination Date, calculated in accordance with the practice in effect on the Determination Date. This amount will be paid in a single lump sum payment on the last day employed or as soon thereafter as practicable.

(IDEX CORPORATION LOGO) Mr. Frank J. Notaro April 24, 2000 Page 2 4) A proportionate bonus, as described in this subparagraph, under the MICP. The portion of the bonus payable will be the amount determined by multiplying a full year's MICP bonus, at your Target Incentive Amount in effect on the Determination Date, calculated in accordance with the practice in effect on the Determination Date, by a fraction the numerator of which is the number of full and partial calendar months in the calendar year which precede the date of the termination of employment and the denominator of which is 12. This amount will be paid in a single lump sum payment on the last day employed or as soon thereafter as practicable. 5) Fringe benefits for a continuing period of twenty-four (24) months following the date of termination of employment. Covered fringe benefits for purposes of this agreement include: (a) term life insurance in an amount in effect on the Determination Date, (b) medical benefits at the level in effect on the Determination Date, (c) to the extent coverage is available under the insurance policy in effect, the personal accident plan at the level in effect on the Determination Date, (d) the use of an IDEX-provided automobile, plus related expenses, comparable to that provided to you on the Determination Date, and (e) other miscellaneous fringe benefits in effect on the Determination Date. Medical benefits will be reduced to the extent of coverage provided by subsequent employers. For purposes of COBRA health care continuation coverage, the "qualifying event" will be deemed to have occurred at the end of the twenty-four (24) month period following termination of employment. 6) For a twenty-four (24) month period following the date of your termination of employment, IDEX will promptly pay or reimburse you for expenses, in an aggregate amount not to exceed 10% of your annual base salary, at the rate in effect on the Determination Date, incurred by you for outplacement services, which may include consultants, reasonable travel, rental of an office off IDEX's premises, secretarial support, and photocopying, telephone, and other miscellaneous office expenses.

(IDEX CORPORATION LOGO) Mr. Frank J. Notaro April 24, 2000 Page 3 7) For a sixty (60) month period following the date of the Executive's termination of employment, the Corporation will continue any indemnification agreement with the Executive and will provide directors' and officers' liability insurance insuring the Executive. That coverage will have limits and scope of coverage not less than that in effect immediately prior to the change in control. At your request, IDEX will cause a certificate of insurance, in a form satisfactory to you, verifying this coverage to be provided to you on an annual basis. 8) You shall be fully vested in your accrued benefit under any qualified or non-qualified pension or profit sharing plan maintained by IDEX, provided, however, if the terms of such plan do not permit acceleration of full vesting, you will receive a lump sum payment on the last day employed, or as soon thereafter as practicable, in an amount equal to the value of your accrued benefit which was not vested. 9) Vesting and the ability to exercise stock options granted to you will be governed by the terms of the stock option plan under which the options were granted and the terms of the option agreement. Notwithstanding anything in this letter agreement or any other agreement to the contrary, in the event it is determined that any payments or distributions by IDEX or any affiliate (as defined under the Securities Act of 1933, as amended, and the regulations thereunder) thereof or any other person to or for the benefit of you, whether paid or payable pursuant to the terms of this letter agreement, or pursuant to any other agreement or arrangement with IDEX or any such affiliate ("Payments"), would be subject to the excise tax imposed by Section 4999 of the Internal Revenue Code of 1986, as amended, or any successor provision, or any interest or penalties with respect to such excise tax (such excise tax, together with any such interest and penalties, are hereinafter collectively referred to as the "Excise Tax"), then you will be entitled to receive an additional payment from IDEX (a "Gross-Up Payment") in an amount such that after payment by you of all taxes (including, without limitation, any interest or penalties imposed with respect to such taxes and any Excise Tax) imposed upon the Gross-Up Payment, you retain an amount of the Gross-Up Payment equal to the Excise Tax imposed upon the Payments. The amount of the Gross-Up Payment will be calculated by

(IDEX CORPORATION LOGO) Mr. Frank J. Notaro April 24, 2000 Page 4 the Corporation's independent accounting firm, engaged immediately prior to the event that triggered the payment, in consultation with the Corporation's outside legal counsel. For purposes of making the calculations required by this Section, the accounting firm may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code, provided that the accounting firm's determinations must be made with substantial authority (within the meaning of Section 6662 of the Code). The Gross-Up Payment will be paid on your last day employed or on the occurrence of the event that results in the imposition of the Excise Tax, if later. If the precise amount of the Gross-Up Payment cannot be determined on the date it is to be paid, an amount equal to the best estimate of the Gross-Up Payment will be made on that date and, within ten (10) days after the precise calculation is obtained, either IDEX will pay any additional amount to you or you will pay any excess amount to IDEX, as the case may be. If subsequently the Internal Revenue Service (IRS) claims that any additional Excise Tax is owing, an additional Gross-Up Payment will he paid to you within thirty (30) days of your providing substantiation of the claim made by the IRS. After payment to you of the Gross-Up Payment, you will provide to IDEX any information reasonably requested by IDEX relating to the Excise Tax, you will take such actions as IDEX reasonable requests to contest such Excise Tax, cooperate in good faith with IDEX to effectively contest the Excise Tax and permit IDEX to participate in any proceedings contesting the Excise Tax. IDEX will bear and pay directly all costs and expenses (including any interest or penalties on the Excise Tax), and indemnify and hold you harmless, on an after-tax basis, from all such costs and expenses related to such contest. Should it ultimately be determined that any amount of an Excise Tax is not properly owed, you will refund to IDEX the related amount of the Gross-Up Payment. For purposes of this letter agreement, "Change of Control" shall have the same meaning as under the Amended and Restated IDEX Corporation Supplemental Executive Retirement Plan as in effect on the date of this letter. For the purposes of this letter agreement, Termination of Service is defined as (1) a termination of your employment by IDEX for any reason other than for Cause, as hereinafter defined; (2) your reasonable belief that there has been a material diminution in responsibilities, duties, title, reporting responsibilities within the business organization, status, role or authority (without limiting the generality of the foregoing, such a material diminution in

(IDEX CORPORATION LOGO) Mr. Frank J. Notaro April 24, 2000 Page 5 responsibilities, duties, title, reporting responsibilities within the business organization, status, role or authority will be deemed to have taken place if any of the following occur: (a) you cease to be an officer of a reporting company under the Securities Exchange Act of 1934, (b) you retain the position as an officer of the reporting company but your primary responsibilities, duties, title, status, role or authority are with an entity within the business organization which is not the reporting company or (c) your degree of involvement in executive decision making relating to IDEX has been materially diminished); (3) IDEX moves your primary worksite to a location outside of the Northbrook, Illinois region which necessitates, in your reasonable judgment, your required relocation from your current residence which you choose not to accept; (4) a reduction in your annual base salary, reduction in the aggregate compensation provided to you (aggregate compensation to be determined by taking into consideration, without limitation, the target level of MICP Awards (other than changes in award amounts which are the result of IDEX performance), retirement or pension plans, nonqualified deferred compensation plans, stock option awards, severance benefits, or any other fringe benefit plan), or degradation in working conditions or (5) if following a Change of Control where IDEX Corporation is no longer the ultimate parent corporation, the failure of the then ultimate parent corporation (a) to appoint you to a position with the then ultimate parent corporation having the same responsibilities, duties, title, reporting responsibilities within the business organization, status, role and authority as you now hold with IDEX, (b) to acknowledge and assume, in writing, this letter agreement at the time of the Change of Control, or (c) to acknowledge and assume, in writing, the indemnification agreement with you which is in effect at the time the Change of Control. After notification to you or your obtaining specific and reliable information which gives rise to your reasonable belief, that one of the preceding events is to occur in the near future, you may, after providing reasonable notice, voluntarily terminate your employment (which, if prior to the happening of the event, must be effective no earlier than, and be contingent on, the occurrence of the event) and the termination will be deemed a Termination of Service. If a Change of Control occurs and your responsibilities, duties, title, reporting responsibilities within the business organization, status, role or authority are reduced or in any manner adversely affected prior to the date of the Change of Control (hereafter referred to as a "Modification"), and if you reasonably demonstrate that the modification was at the request of a third party who has taken steps reasonably calculated to effect a Change of Control or otherwise arose, directly or indirectly, in connection with, or in anticipation of, a Change of Control, then the level of your responsibilities, duties, title, reporting

(IDEX CORPORATION LOGO) Mr. Frank J. Notaro April 24, 2000 Page 6 responsibilities within the business organization, status, role or authority for purposes of this letter agreement shall be those in effect on the date immediately prior to the Modification. If your termination of employment occurs prior to a Change of Control and if you reasonably demonstrate that the termination was at the request of a third party who has taken steps reasonably calculated to effect a Change of Control or otherwise arose, directly or indirectly, in connection with, or in anticipation of, a Change of Control, then your termination will be deemed a Termination of Service. If one of the events which would be a Termination of Service occurs, and if your termination of employment at that time would be in a period of time during which you would be unable to exercise stock options or sell shares of IDEX or its successor, either by law or contractual agreement (a "Restrictive Period"), then you may continue in employment until a reasonable period after the Restrictive Period ends and your subsequent termination of employment will be a Termination of Service. For purposes of this letter Agreement, "Cause" exists if (1) you breach, in a substantive and material manner, your fiduciary duty to IDEX, (2) you commit a felony criminal act, or (3) you fail, after repeated requests of the Chief Executive Officer of IDEX, which have been documented to you in writing, to perform the material duties assigned to you (the nature of which must be consistent with the duties assigned to you prior to the Change of Control or prior to any modification of your assigned duties made in connection with, or anticipation of, such Change of Control). For purposes of this letter agreement, the term "Determination Date" means the date immediately prior to the date of (1) payment of any Severance Benefit, (2) the Change of Control, (3) your Termination of Service, or (4) your last day of employment, on whichever of the four preceding dates a factor (i.e. the rate, level, amount, practice, quality or other factor, as the context may indicate) used to calculate a Severance Benefit under this letter agreement is the factor which will result, with respect to such Severance Benefit, in the greatest or largest benefit to be provided. For avoidance of doubt, the Determination Date may be different with respect to different Severance Benefits. If IDEX, or any entity which has an obligation to you under this letter agreement, fails to honor any provision of this letter agreement or if a contest or dispute as to the terms of this letter agreement arises, all legal fees and expenses incurred by you to enforce this agreement or to contest or dispute its terms will

(IDEX CORPORATION LOGO) Mr. Frank J. Notaro April 24, 2000 Page 7 be paid, or at your request, advanced, by IDEX to you or directly to your attorney, as you may direct. To the extent that this letter agreement provides a larger or greater separate Severance Benefit than may be provided to you pursuant to any policy, program, contract or arrangement previously adopted by IDEX prior to your Termination of Service, this letter agreement will supersede and be in full substitution of such other policy, program, contract or arrangement with respect to the larger or greater separate Severance Benefit to be provided. To the extent that any policy, program, contract or arrangement adopted by IDEX prior to your Termination of Service provides a larger or greater separate severance benefit than provided to you pursuant to this letter agreement, such other policy, program, contract or arrangement will supersede and be in full substitution of this letter agreement with respect to the larger or greater separate Severance Benefit to be provided. This letter agreement shall apply to a Change of Control that occurs on or before the date on which IDEX provides written notice to you that the terms this letter agreement will terminate (the date so specified in the notice will not be less than two years following the date of such notice), or, if a Change of Control is pending as of such date, this letter agreement will also apply if that Change of Control does occur in a reasonable period thereafter. If a Change of Control has not occurred as of the date specified in the notice, or is pending as of the date so specified in the notice and is not subsequently consummated in a reasonable period thereafter, this letter agreement shall be null and void. The terms of this letter agreement will be governed by the laws of the State of Illinois and will be binding on IDEX and its successors (who consent to jurisdiction in the State of Illinois with respect to the subject matter of this letter agreement) and will inure to the benefit of your heirs. You will not be required to mitigate the amount of any payment or benefit provided for in this letter agreement by obtaining other employment or other sources of income or benefits nor will the amount of any payment or benefit be reduced by offset against any amount claimed to be owed by you to IDEX (except to the extent that medical benefits are provided by a subsequent employer). For any matter in this letter agreement wherein the determination of the existence of any fact or other matter is indicated to be in your reasonable belief, your belief will be respected and upheld provided you have obtained specific and reliable information giving rise to your reasonable belief and unless IDEX demonstrates, by a preponderance of

(IDEX CORPORATION LOGO) Mr. Frank J. Notaro April 24, 2000 Page 8 the evidence, that the basis for your belief was arbitrary or capricious. If any provision of this letter agreement is held invalid or unenforceable for any reason, all other provisions shall remain in effect. All notices and other communications given pursuant to this letter agreement will be deemed to have been properly given if hand delivered or mailed, addressed to the appropriate party at the address as shown on the first page of this letter agreement, postage prepaid, by certified or registered mail, return receipt requested and, in the case of notice to IDEX to the attention of the President. A copy of any notice sent must also be sent to Hodgson, Russ, Andrews, Woods & Goodyear, LLP, 1800 One M&T Plaza, Buffalo, New York 14203, Attention: Richard E. Heath, Esq. and Richard W. Kaiser, Esq. Any party may from time to time designate, by written notice given in accordance with these provisions, any other address or party to which such notice or communication or copies thereof shall be sent.

IDEX CORPORATION 2005 ANNUAL REPORT Management's Discussion and Analysis of Financial Condition and Results of Operations CAUTIONARY STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT The "Historical Overview and Outlook" and the "Liquidity and Capital Resources" sections of this management's discussion and analysis of our operations contain 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," "we believe," "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 filing. 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 our order rates and results, particularly in light of the low levels of order backlogs we typically maintain; our 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 we operate; interest rates; capacity utilization and the effect this has on costs; labor markets; market conditions and material costs; and developments with respect to contingencies, such as litigation and environmental matters. The forward-looking statements included here are only made as of the date of this report, and we undertake no obligation to publicly update them to reflect subsequent events or circumstances. Investors are cautioned not to rely unduly on forward-looking statements when evaluating the information presented here. HISTORICAL OVERVIEW AND OUTLOOK IDEX Corporation (IDEX or the Company) sells a broad range of pump products, dispensing equipment and other engineered products to a diverse customer base in the United States and other countries around the world. Accordingly, our businesses are affected by levels of industrial activity and economic conditions in the U.S. and in other countries where our products are sold and by the relationship of the U.S. dollar to other currencies. Levels of capacity utilization and capital spending in certain industries and overall industrial activity are among the factors that influence the demand for our products. IDEX consists of three reporting segments: Pump Products Group, Dispensing Equipment Group and Other Engineered Products Group. The Pump Products Group produces a wide variety of pumps, compressors, flow meters, injectors and valves, and related controls for the movement of liquids, air and gases. The Dispensing Equipment Group produces highly engineered equipment for dispensing, metering and mixing colorants, paints, inks and dyes, and personal care products; refinishing equipment; and centralized lubrication systems. The Other Engineered Products Group produces firefighting pumps, valves, controls, rescue tools, lifting bags and other components and systems for the fire and rescue industry; and engineered stainless steel banding and clamping devices used in a variety of industrial and commercial applications. IDEX has a history of achieving above-average operating margins. Our operating margins have exceeded the average operating margin of the companies that comprise the Value Line Composite Index (VLCI) every year since 1988. We view the VLCI operating performance statistics as a proxy for an average industrial company. Our operating margins are influenced by, among other things, utilization of facilities as sales volumes change and inclusion of newly acquired businesses. Some of our key 2005 financial highlights were as follows: - Orders were a record $1,057.0 million, 12% higher than a year ago; base business orders--excluding 2004 acquisitions and foreign currency translation--were up 10%. - Sales of $1,043.3 million set a new record and were up 12% from last year; base business sales--excluding 2004 acquisitions and foreign currency translation--were up 10%. - Gross margins improved 60 basis points to 40.6% of sales, while operating margins at 17.5% were 140 basis points higher than 2004. - Net income rose 27% to $109.8 million. - Diluted EPS of $2.08 was 40 cents ahead of last year. - Cash flows from operating activities rose 1% and reached an all time high of $144.9 million. We are pleased with our results in 2005. Our business units again delivered--with double digit increases in orders, sales, and net income as well as strong cash flow. All three business segments generated organic sales growth and continued operating margin expansion as a result of our operational excellence and new product and market initiatives. We enter 2006 well positioned for continued growth and are using all the tools at our disposal to drive revenues, profitability and cash generation. The following forward-looking statements are qualified by the cautionary statement under the Private Securities Litigation Reform Act set forth above. 18

IDEX CORPORATION 2005 ANNUAL REPORT We expect economic conditions to remain favorable as we continue to leverage rapid process improvement to meet customer needs, drive earnings and fund innovation to support our organic growth. As a short cycle business, we are mindful that our financial performance is reliant on the current pace of incoming orders. Although we have limited visibility on future business conditions, we believe IDEX is well positioned for earnings expansion, based on our lower cost levels resulting from our operational excellence discipline, our investments in new products, applications and global markets, and our pursuit of strategic acquisitions to complement our longer-term profitable growth. RESULTS OF OPERATIONS The following is a discussion and analysis of our financial position and results of operations for each of the three years in the period ended December 31, 2005. For purposes of this discussion and analysis section, reference is made to the table on page 20 and the Consolidated Statements of Operations on page 26. PERFORMANCE IN 2005 COMPARED WITH 2004 Orders, sales, net income and earnings per share were higher in 2005 compared with 2004. New orders in 2005 totaled $1,057.0 million and were 12% higher than the prior year. Excluding foreign currency translation and the impact of the three acquisitions made since the beginning of 2004 (Systec--April 2004; Scivex--May 2004 and Dinglee--July 2004), orders were 10% higher than a year ago. Sales in 2005 of $1,043.3 million were 12% higher than the $928.3 million recorded a year ago. Base business sales rose 10%, while acquisitions accounted for an improvement of 2%. Base business sales increased in all three of the Company's reporting segments. Domestic base sales were up 12% over the prior year, while base sales to international customers increased 7% in 2005. Sales to international customers represented 43% of the total, compared with 44% in 2004. In 2005, the Pump Products Group contributed 59% of sales and 54% of operating income, the Dispensing Equipment Group accounted for 18% of sales and 19% of operating income, and the Other Engineered Products Group represented 23% of sales and 27% of operating income. Pump Products Group sales of $620.7 million in 2005 increased $78.3 million, or 14%, compared with 2004. The 2004 acquisitions of Systec and Scivex accounted for a 3% sales improvement, while base business activity provided an 11% increase. In 2005, base business sales increased 12% domestically, while base international sales increased 7%. Base business sales to customers outside the U.S. were 37% of total group sales in 2005, down from 38% in 2004. Dispensing Equipment Group sales of $187.8 million increased by $17.6 million, or 10%, in 2005 compared with the prior year, due to a 9% increase in base business activity and favorable foreign currency translation of 1%. Base domestic sales increased 20% compared with 2004, while base international sales increased 2%. Base sales to customers outside the U.S. were 59% of total group sales in 2005, down from 61% in 2004. Other Engineered Products Group sales of $239.0 million increased by $20.0 million, or 9%, in 2005 compared with 2004. Base business activity drove the 9% increase in sales. In 2005, base sales increased 8% domestically, while base international sales increased 11%. Base business sales to customers outside the U.S. were 46% of total group sales in 2005, up from 39% in 2004. Gross profit of $423.8 million in 2005 was $53.0 million, or 14%, higher than 2004. As a percent of sales, gross profit was 40.6% in 2005, which represented a 60 basis point increase from 40.0% in 2004. The higher gross profit margin primarily reflects volume leverage and the Company's global sourcing and operational excellence initiatives. Selling, general and administrative (SG&A) expenses increased to $241.1 million in 2005 from $221.4 million in 2004. This increase reflects the deliberate reinvestment in the business to drive long-term growth, volume-related expenses and acquisitions. As a percent of net sales, SG&A expenses were 23.1%, an improvement of 80 basis points compared with the 23.9% achieved in 2004. Operating income increased by $33.4 million, or 22%, to $182.8 million in 2005 from $149.4 million in 2004, primarily due to higher 2005 gross profit, offset by increased SG&A expenses. Operating margins in 2005 were 17.5% of sales, an improvement of 140 basis points compared with the 16.1% achieved in 2004. In the Pump Products Group, operating income of $114.4 million and operating margin of 18.4% increased in 2005 compared with the $93.4 million and 17.2% recorded in 2004. Operating income for the Dispensing Equipment Group increased to $40.8 million in 2005 from $33.5 million last year, and operating margins improved to 21.7% from 19.7% recorded in 2004. Operating income in the Other Engineered Products Group of $56.7 million and operating margin of 23.7% increased from the $47.1 million and 21.5% achieved in 2004. The margin improvement in all three segments was mostly attributable to the improved sales volumes and other factors discussed above. 19

IDEX CORPORATION 2005 ANNUAL REPORT Other income of $.6 million in 2005 was $1.3 million higher than $.7 million of expense in 2004. In 2005, we benefited from foreign currency exchange gains. Additionally, in 2004, we incurred hurricane-related costs at one of our business units as well as certain costs associated with the refinancing of our credit facility. Interest expense decreased to $14.4 million in 2005 from $14.8 million in 2004. The decrease was principally due to lower debt levels resulting from debt paydowns, partially off-set by higher interest rates. The provision for income taxes increased to $59.1 million in 2005 from $47.5 million in 2004. The effective tax rate decreased to 35.0% in 2005 from 35.5% in 2004 due to a favorable impact from foreign tax credits and the additional benefit realized from the deduction for income from qualified domestic production activity, partially offset by a reduction in research and development credits. Net income was $109.8 million, or $2.08 per share, compared with $86.4 million, or $1.68 per share, in 2004. PERFORMANCE IN 2004 COMPARED WITH 2003 Orders, sales, net income and earnings per share were higher in 2004 compared with 2003. New orders in 2004 totaled $942.4 million and were 18% higher than the prior year. Excluding the impact of the six acquisitions made since the beginning of 2003 (Sponsler-June 2003; Classic-September 2003; Vetter-January 2004; Systec-April 2004; Scivex-May 2004 and Dinglee-July 2004) and foreign currency translation, orders were 9% higher in 2004 compared with 2003. Sales in 2004 of $928.3 million were 16% higher than the $797.9 million recorded in 2003. Acquisitions and foreign currency translation accounted for an improvement of 6% and 3%, respectively, while base business sales rose 7%. Base business sales increased in all three of the Company's reporting groups. Domestic base sales were up 10% over the prior year, while base sales to international customers increased 2% in 2004. Base sales to international customers represented 43% of the total, compared with 45% in 2003. In 2004, the Pump Products Group contributed 58% of sales and 54% of operating income, the Dispensing Equipment Group accounted for 18% of sales and 19% of operating income, and the Other Engineered Products Group represented 24% of sales and 27% of operating income. Pump Products Group sales of $542.3 million in 2004 increased $85.8 million, or 19%, compared with 2003. Acquisitions and foreign currency translation accounted for an 8% and 2% sales improvement, respectively, while base business activity provided a 9% increase. In 2004, base business sales increased 12% domestically, while base international sales increased 6%. Base business sales to customers outside the U.S. were 38% of total group sales in 2004, down from 40% in 2003. Dispensing Equipment Group sales of $170.2 million increased by $11.0 million, or 7%, in 2004 compared with the prior year, due to favorable foreign currency translation of 5% and a 2% increase in base business activity. Base domestic sales increased 7% compared with 2003, while base international sales decreased 2%. Base sales to customers outside the U.S. were 61% of total group sales in 2004, down from 63% in 2003. Other Engineered Products Group sales of $219.0 million increased by $34.0 million, or 18%, in 2004 compared with 2003. Acquisitions accounted for an increase of 7%, foreign currency translation added 4% and base business activity contributed 7%. In 2004, base sales increased 13% domestically, while base international sales decreased 1%. Base business sales to customers outside the U.S. were 39% of total group sales in 2004, down from 43% in 2003. Gross profit of $370.8 million in 2004 was $61.5 million, or 20%, higher than 2003. As a percent of sales, gross profit was 40.0% in 2004, which represented a 120 basis point increase from 38.8% in 2003. The higher gross profit margin primarily reflects reduced material costs from our global sourcing and operational excellence initiatives, volume leverage, and price increases, all of which more than offset cost increases and additional expenses. SG&A expenses increased to $221.4 million in 2004 from $199.5 million in 2003. This increase was partly due to the inclusion of six acquisitions that incrementally added $10.0 million of cost. This increase also reflects the deliberate reinvestment in the business to drive organic growth as well as certain volume-related cost increases. As a percent of net sales, SG&A expenses were 23.9% in 2004, down from 25.0% in 2003. Operating income increased by $39.5 million, or 36%, to $149.4 million in 2004 from $109.9 million in 2003, primarily due to higher 2004 gross profit, offset by increased SG&A expenses. Operating margins in 2004 were 16.1% of sales, compared with 13.8% in 2003. 21

IDEX CORPORATION 2005 ANNUAL REPORT Management's Discussion and Analysis of Financial Condition and Results of Operations (continued) In the Pump Products Group, operating income of $93.4 million and operating margin of 17.2% increased in 2004 compared with the $70.4 million and 15.4% recorded in 2003. Operating income for the Dispensing Equipment Group increased to $33.5 million in 2004 from $25.7 million last year, and operating margins improved to 19.7% from 16.2% recorded in 2003. Operating income in the Other Engineered Products Group of $47.1 million and operating margin of 21.5% increased from the $33.0 million and 17.8% achieved in 2003. The margin improvement in all three segments was mostly attributable to the improved sales volumes and other factors discussed above. Other expense of $.7 million in 2004 was $1.6 million higher than $.9 million of income in 2003. In 2004, we incurred hurricane-related costs at one of our business units as well as certain costs associated with the refinancing of our credit facility. In 2003, we benefited from a foreign currency exchange gain related to the anticipated funding of the Vetter acquisition in January 2004. Interest expense increased to $14.8 million in 2004 from $14.1 million in 2003. The increase was principally due to higher debt levels resulting from our recent acquisitions as well as a slightly higher interest rate environment. The provision for income taxes increased to $47.5 million in 2004 from $34.3 million in 2003. The effective tax rate was 35.5% for both periods. Net income was $86.4 million, or $1.68 per share, compared with $62.4 million, or $1.25 per share, in 2003. LIQUIDITY AND CAPITAL RESOURCES At December 31, 2005, working capital was $194.2 million and our current ratio was 2.3 to 1. Cash flows from operating activities increased by $1.8 million, or 1%, to $144.9 million in 2005, mainly due to the improved operating results discussed earlier offset by an increase in working capital requirements. Cash flows from operating activities were more than adequate to fund capital expenditures of $23.0 million and $21.1 million in 2005 and 2004, respectively. Capital expenditures were generally for machinery and equipment that improved productivity, tooling to support IDEX's global sourcing initiative, business system technology and replacement of equipment and facilities. Management believes that IDEX has ample capacity in its plant and equipment to meet expected needs for future growth in the intermediate term. In 2004, the Company acquired Vetter, Systec, Scivex and Dinglee at a cost of $44.8 million, $22.4 million, $98.6 million and $4.1 million, respectively. In 2004, the Company also paid $1.1 million in settlement of a purchase price contingency related to the 2003 acquisition of Classic. These payments were financed under the Company's credit facilities. In addition to the $150.0 million of 6.875% Senior Notes (Senior Notes) due February 15, 2008, the Company also maintains a $600.0 million domestic multi-currency bank revolving credit facility (Credit Facility), which expires on December 14, 2009. With no borrowings outstanding under the Credit Facility at December 31, 2005, and outstanding letters of credit totaling $4.7 million, the maximum amount available under the Credit Facility was $595.3. million. The Credit Facility contains a covenant that limits total debt outstanding to 3.25 times operating cash flow, as defined in the agreement. Our total debt outstanding was $160.0 million at December 31, 2005, and based on the covenant, total debt outstanding was limited to $693.3 million. Interest is payable quarterly on the outstanding balance at the bank agent's reference rate or, at the Company's election, at LIBOR plus an applicable margin. The applicable margin is based on the credit rating of our Senior Notes, and can range from 27 basis points to 75 basis points. Based on the Company's BBB rating at December 31, 2005, the applicable margin was 55 basis points. We also pay an annual fee of 15 basis points on the total Credit Facility. We also have a one-year, renewable $30.0 million demand line of credit (Short-Term Facility), which expires on December 12, 2006. Borrowings under the Short-Term Facility are at LIBOR plus the applicable margin in effect under the Credit Facility. At December 31, 2005, there were no borrowings outstanding under the Short-Term Facility. We believe the Company will generate sufficient cash flow from operations for the next 12 months and over the long term to meet its operating requirements, interest on all borrowings, required debt repayments, any authorized share repurchases, planned capital expenditures, and annual dividend payments to holders of common stock. In the event that suitable businesses are available for acquisition upon terms acceptable to the Board of Directors, we may obtain all or a portion of the financing for the acquisitions through the incurrence of additional borrowings. 22

IDEX CORPORATION 2005 ANNUAL REPORT CONTRACTUAL OBLIGATIONS, COMMITMENTS AND OFF-BALANCE SHEET ARRANGEMENTS Our contractual obligations and commercial commitments include rental payments under operating leases, payments under capital leases, and other long-term obligations arising in the ordinary course of business. There are no identifiable events or uncertainties, including the lowering of our credit rating that would accelerate payment or maturity of any of these commitments or obligations. The Company also has obligations with respect to its pension and postretirement medical benefit plans, which are not included in the table below. See Note 13 of the Notes to Consolidated Financial Statements. The following table summarizes our significant contractual obligations and commercial commitments at December 31, 2005, and the future periods in which such obligations are expected to be settled in cash. In addition, the table reflects the timing of principal and interest payments on outstanding borrowings. Additional detail regarding these obligations are provided in the Notes to Consolidated Financial Statements, as referenced in the table: Less More Payments Due than 1-3 3-5 than by Period Total 1 Year Years Years 5 Years - ----------------- -------- ------- -------- ------ ------- (in thousands) Borrowings (Note 4)(1) $184,673 $13,793 $169,675 $1,074 $ 131 Operating lease commitments (Note 5) 20,250 6,699 8,309 3,441 1,801 Capital lease obligations(2) 6,362 955 1,251 1,374 2,782 Purchase obligations(3) 39,645 36,418 3,199 28 -- -------- ------- -------- ------ ------ Total contractual obligations(4) $250,930 $57,865 $182,434 $5,917 $4,714 ======== ======= ======== ====== ====== (1) Includes interest payments based on contractual terms and current interest rates for variable debt. (2) Comprised primarily of property leases. (3) Comprised primarily of inventory commitments. (4) Comprised of liabilities recorded on the balance sheet of $184,319, and obligations not recorded on the balance sheet of $66,611. CRITICAL ACCOUNTING POLICIES We believe that the application of the following accounting policies, which are important to our financial position and results of operations, requires significant judgments and estimates on the part of management. For a summary of all of our accounting policies, including the accounting policies discussed below, see Note 1 of the Notes to Consolidated Financial Statements. Revenue recognition--We recognize revenue from product sales when title passes and the risks of ownership have passed to the customer. Our customary terms are FOB shipping point. Based on our historical experience, we estimate and record provisions for sales returns and sales allowances in the period the related products are sold. To the extent actual results differ from these estimated amounts, results could be adversely affected. Noncurrent assets--The Company evaluates the recoverability of certain noncurrent assets utilizing various estimation processes. In particular, the recoverability of December 31, 2005 balances for goodwill and intangible assets of $691.9 million and $28.6 million, respectively, are subject to estimation processes, which depend on the accuracy of underlying assumptions, including future operating results. The Company evaluates the recoverability of each of these assets based on estimated business values and estimated future cash flows (derived from estimated earnings and cash flow multiples). The recoverability of these assets depends on the reasonable- ness of these assumptions and how they compare with the eventual operating performance of the specific businesses to which the assets are attributed. To the extent actual business values or cash flows differ from those estimated amounts, the recoverability of these noncurrent assets could be affected. Income taxes--The Company accounts for income taxes in accordance with Statement of Financial Accounting Standards (SFAS) No. 109, "Accounting for Income Taxes." Under SFAS No. 109, deferred income tax assets and liabilities are determined based on the estimated future tax effects of differences between the financial statement and tax bases of assets and liabilities based on currently enacted tax laws. The Company's tax balances are based on management's interpretation of the tax regulations and rulings in numerous taxing jurisdictions. Future tax authority rulings and changes in tax laws and future tax planning strategies could affect the actual effective tax rate and tax balances recorded by the Company. Contingencies and litigation--We are currently involved in certain legal and regulatory proceedings and, as required and where it is reasonably possible to do so, have accrued our estimates of the probable costs for the resolution of these matters. These estimates have been developed in consultation with outside counsel and are based upon an analysis of potential results, assuming a combination of litigation and settlement strategies. It is possible, however, that future operating results for any particular quarterly or annual period could be materially affected by changes in our assumptions or the effectiveness of our strategies related to these proceedings. 23

IDEX CORPORATION 2005 ANNUAL REPORT Management's Discussion and Analysis of Financial Condition and Results of Operations (continued) Defined benefit retirement plans--The plan obligations and related assets of defined benefit retirement plans are presented in Note 13 of the Notes to Consolidated Financial Statements. Plan assets, which consist primarily of marketable equity and debt instruments, are valued using market quotations. Plan obligations and the annual pension expense are determined by consulting with actuaries using a number of assumptions provided by the Company. Key assumptions in measuring the plan obligations include the discount rate at which the obligations could be effectively settled and the anticipated rate of future salary increases. Key assumptions in the determination of the annual pension expense include the discount rate, the rate of salary increases, and the estimated future return on plan assets. To the extent actual amounts differ from these assumptions and estimated amounts, results could be adversely affected. NEW ACCOUNTING PRONOUNCEMENTS In December 2004, the Financial Accounting Standards Board (FASB) issued SFAS No. 123 (revised 2004), "Share-Based Payment" (SFAS 123R). SFAS 123R replaces SFAS No. 123 and supersedes APB Opinion No. 25. SFAS No. 123R will require the fair value of all stock option awards issued to employees to be recorded as an expense over the related vesting period. SFAS 123R also requires the recognition of compensation expense for the fair value of any unvested stock option awards outstanding at the date of adoption. See Note 1 for the pro forma effect on our net income and earnings per share of applying SFAS No. 123. SFAS 123R is effective for public companies for annual periods that begin after June 15, 2005. Accordingly, we will adopt SFAS 123R in the first quarter of 2006. The Company is still evaluating the impact of adopting this SFAS in 2006, but we anticipate an annual pre-tax expense of approximately $8.0 million, or 10 cents per diluted share, net of tax. In March 2005, the FASB issued FASB Interpretation No. 47 (FIN 47), "Accounting for Conditional Asset Retirement Obligations." FIN 47 clarifies that the term conditional asset retirement obligation, as used in SFAS No. 143, "Accounting for Asset Retirement Obligations," refers to a legal obligation to perform an asset retirement activity in which the timing and/or method of settlement are conditional on a future event that may or may not be within the control of the entity. FIN 47 is effective no later than the end of fiscal years ending after December 15, 2005. The adoption of FIN 47 did not have a material impact on our results of operations, financial condition or cash flows. MARKET RISK We are subject to market risk associated with changes in interest rates and foreign currency exchange rates. Interest rate exposure is limited to the $160.0 million of total debt outstanding at December 31, 2005. Approximately 6% of the debt is priced at interest rates that float with the market. A 50 basis point movement in the interest rate on the floating rate debt would result in an approximate $.1 million annualized increase or decrease in interest expense and cash flows. The remaining debt is fixed rate debt. A treasury risk management policy, adopted by the Board of Directors, describes the procedures and controls over derivative financial and commodity instruments, including interest rate swaps. Under the policy, we do not use derivative financial or commodity instruments for trading purposes, and the use of these instruments is subject to strict approvals by senior officers. Typically, the use of derivative instruments is limited to interest rate swaps on the Company's outstanding long-term debt. As of December 31, 2005, the Company did not have any derivative instruments outstanding. Our foreign currency exchange rate risk is limited principally to the euro and British pound. We manage our foreign exchange risk principally through invoicing our customers in the same currency as the source of our products. As a result, the Company's exposure to any movement in foreign currency exchange rates is immaterial to the Consolidated Statements of Operations. 24

IDEX CORPORATION 2005 ANNUAL REPORT Notes to Consolidated Financial Statements (in thousands except per share amounts) 1. SIGNIFICANT ACCOUNTING POLICIES BUSINESS IDEX Corporation (IDEX or the Company) is a manufacturer of a broad range of pumps, metering products, dispensing equipment, and other engineered products sold to a diverse customer base in a variety of industries in the U.S. and internationally. Its products include industrial pumps, compressors, flow meters, injectors and valves, and related controls for use in a wide variety of process applications; precision- engineered equipment for dispensing, metering and mixing paints, and personal care products; refinishing equipment; centralized lubrication systems; and engineered products for industrial and commercial markets, including fire and rescue, transportation equipment, oil and gas, electronics, and communications. These activities are grouped into three business segments: Pump Products, Dispensing Equipment and Other Engineered Products. PRINCIPLES OF CONSOLIDATION The consolidated financial statements include the Company and its subsidiaries. Significant intercompany transactions and accounts have been eliminated. USE OF ESTIMATES The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and judgments that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities, and reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. The principal areas of estimation reflected in the financial statements are sales returns and allowances, warranties, noncurrent assets, income taxes, contingencies and litigation, and defined benefit retirement plans. REVENUE RECOGNITION IDEX recognizes revenue from product sales when title passes and the risks of ownership have passed to the customer. Customary terms are FOB shipping point. Based on its historical experience, the Company estimates and records provisions for sales returns and sales allowances in the period the related products are sold. CASH EQUIVALENTS The Company considers all highly liquid debt instruments purchased with an original maturity of three or fewer months to be cash equivalents. INVENTORIES Inventories are stated at the lower of cost or market. Cost-which includes labor, material and factory overhead-is determined on the first-in, first-out (FIFO) basis or the last-in, first-out (LIFO) basis. A reserve for excess inventory is recorded for inventory on hand in excess of anticipated or historical usage. An obsolescence reserve is recorded for inventory made obsolete by marketplace, product or engineering changes. DEBT EXPENSES Expenses incurred in securing and issuing debt are amortized over the life of the related debt and are included in interest expense in the Consolidated Statements of Operations. EARNINGS PER COMMON SHARE Earnings per common share (EPS) are computed by dividing net income by the weighted average number of shares of common stock (basic) plus common stock equivalents and unvested restricted shares (diluted) outstanding during the year. Common stock equivalents consist of stock options and deferred compensation units (DCUs) and have been included in the calculation of weighted average shares outstanding using the treasury stock method. Basic weighted average shares outstanding reconciles to diluted weighted average shares outstanding as follows: 2005 2004 2003 ------ ------ ------ Basic weighted average common shares outstanding 51,392 50,073 48,795 Dilutive effect of stock options, DCUs and unvested restricted shares 1,328 1,275 1,178 ------ ------ ------ Diluted weighted average common shares outstanding 52,720 51,348 49,973 ====== ====== ====== Options to purchase approximately .2 and .1 million shares of common stock as of December 31, 2005 and 2004, respectively, were not included in the computation of diluted EPS because the exercise price was greater than the average market price of the Company's common stock and, therefore, the effect of their inclusion would be antidilutive. STOCK OPTIONS The Company uses the intrinsic-value method of accounting for stock option awards as prescribed by Accounting Principles Board (APB) Opinion No. 25 and, accordingly, does not recognize compensation expense for its stock option awards in the Consolidated Statements of Operations. 29

IDEX CORPORATION 2005 ANNUAL REPORT Notes to Consolidated Financial Statements (continued) The following table reflects pro forma net income and EPS had the Company elected to adopt the fair value approach of Statement of Financial Accounting Standards (SFAS) No. 123, "Accounting for Stock-Based Compensation." 2005 2004 2003 -------- ------- ------- NET INCOME As reported $109,803 $86,406 $62,352 Add: Stock-based employee compensation expense, 1,804 1,457 1,196 net of tax Deduct: Total stock-based employee compensation expense determined under fair value based method for all awards, net of tax (8,591) (6,839) (5,985) -------- ------- ------- Pro forma $103,016 $81,024 $57,563 ======== ======= ======= BASIC EPS As reported $ 2.14 $ 1.73 $ 1.28 Pro forma 2.00 1.62 1.18 ======== ======= ======= DILUTED EPS As reported $ 2.08 $ 1.68 $ 1.25 Pro forma 1.97 1.58 1.15 ======== ======= ======= The fair value of each option grant was estimated on the date of grant using the Black-Scholes option pricing model with the following assumptions for 2005, 2004 and 2003, respectively: dividend yields of 1.50%, 1.55% and 1.84%; volatility of 30.0%, 29.6% and 32.6%; risk-free interest rates of 4.3%, 3.0% and 3.2%; and expected lives of 5.5 years. DEPRECIATION AND AMORTIZATION Depreciation is recorded using the straight-line method. The estimated useful lives used in the computation of depreciation of tangible assets are as follows: Land improvements 10 to 12 years Buildings and improvements 3 to 30 years Machinery and equipment and engineering drawings 3 to 12 years Office and transportation equipment 3 to 10 years Certain identifiable intangible assets are amortized over their estimated useful lives using the straight-line method. The carrying amount of all long-lived assets is evaluated periodically to determine if adjustment to the depreciation or amortization period or to the unamortized balance is warranted. This evaluation is based on the expected utilization of the long-lived assets and the projected, undiscounted cash flows of the operations in which the long-lived assets are used. RESEARCH AND DEVELOPMENT EXPENDITURES Costs associated with research and development are expensed in the year incurred and included in "Cost of sales." Research and development expenses--which include costs associated with developing new products and major improvements to existing products--were $24,213, $21,242 and $17,261 in 2005, 2004 and 2003, respectively. FOREIGN CURRENCY TRANSLATION The functional currency of substantially all operations outside the United States is the respective local currency. Accordingly, those foreign currency balance sheet accounts have been translated using the exchange rates in effect as of the balance sheet date. Income statement amounts have been translated using the average exchange rate for the year. The gains and losses resulting from changes in exchange rates from year to year have been reported in "Cumulative translation adjustment" in the Consolidated Balance Sheets. The effect on the Consolidated Statements of Operations of transaction gains and losses is insignificant for all years presented. FAIR VALUE OF FINANCIAL INSTRUMENTS The carrying amounts of the Company's financial instruments, including cash, trade receivables, accounts payable and accrued expenses, approximate their fair values. CONCENTRATION OF CREDIT RISK IDEX is not overly dependent on a single customer, the largest of which accounted for less than 2% of net sales for all years presented. RECLASSIFICATION Certain reclassifications have been made in the prior years' financial statements to conform to the current year presentation. Specifically, the 2004 and 2003 effect of foreign currency exchange rates on cash and cash equivalents have been reclassified to a separate line outside of operating activities on the Consolidated Statements of Cash Flows. This change in presentation was deemed to be immaterial. NEW ACCOUNTING PRONOUNCEMENTS In December 2004, the Financial Accounting Standards Board (FASB) issued SFAS No. 123 (revised 2004), "Share-Based Payment" (SFAS 123R). SFAS 123R replaces SFAS No. 123 and supersedes APB Opinion No. 25. SFAS 123R will require the fair value of all stock option awards issued to employees to be recorded as an expense over the related vesting period. SFAS 123R also requires the recognition of compensation expense for the fair value of any unvested stock option awards outstanding at the date of adoption. SFAS 123R is effective for public companies for annual periods that begin after June 15, 2005. Accordingly, we will adopt SFAS 123R in the first quarter of 2006. The Company is still evaluating the impact of adopting this SFAS in 2006, but we anticipate an annual pre-tax expense of approximately $8.0 million, or 10 cents per diluted share, net of tax. In March 2005, the FASB issued FASB Interpretation No. 47 (FIN 47) "Accounting for Conditional Asset Retirement Obligations." FIN 47 clarifies that the term conditional asset retirement obligation, as used in SFAS No. 143, "Accounting for Asset Retirement Obligations," refers to a legal obligation 30

IDEX CORPORATION 2005 ANNUAL REPORT to perform an asset retirement activity in which the timing and/or method of settlement are conditional on a future event that may or may not be within the control of the entity. FIN 47 is effective no later than the end of fiscal years ending after December 15, 2005. The adoption of FIN 47 did not have a material impact on the Company's results of operations, financial condition or cash flows. 2. BALANCE SHEET COMPONENTS The components of certain balance sheet accounts at December 31, 2005 and 2004, were as follows: 2005 2004 -------- -------- RECEIVABLES Customers $133,993 $120,696 Other 2,367 3,131 -------- -------- Total 136,360 123,827 Less allowance for doubtful accounts 3,816 4,260 -------- -------- Total receivables--net $132,544 $119,567 ======== ======== INVENTORIES Raw materials $ 52,215 $ 52,824 Work in process 13,138 14,181 Finished goods 61,223 59,973 -------- -------- Total inventories $126,576 $126,978 ======== ======== Inventories that were carried on a LIFO basis amounted to $97,785 and $104,957 at December 31, 2005 and 2004, respectively.

IDEX CORPORATION 2005 ANNUAL REPORT Notes to Consolidated Financial Statements (continued) Amortization of intangible assets was $708 and $638 in 2005 and 2004, respectively. Amortization expense for the next five years is estimated to be consistent with 2005. 4. BORROWINGS Borrowings at December 31, 2005 and 2004 consisted of the following: 2005 2004 -------- -------- Senior Notes $150,000 $150,000 Bank credit facilities -- 64,195 Other borrowings 10,043 11,122 -------- -------- Total borrowings 160,043 225,317 Less current portion 3,144 -- -------- -------- Total long-term borrowings $156,899 $225,317 ======== ======== In February 1998, the Company sold $150 million of Senior Notes due February 15, 2008 (Senior Notes), with a coupon interest rate of 6.875% and an effective rate of 6.919% to maturity. Interest is payable semiannually. The Senior Notes are redeemable at any time at the option of the Company in whole or in part. At December 31, 2005, the fair market value of the Senior Notes was approximately $154 million, based on the quoted market price. The Company also maintains a $600 million domestic multi-currency bank revolving credit facility (Credit Facility), which expires on December 14, 2009. At December 31, 2005, there were no borrowings outstanding under the Credit Facility and outstanding letters of credit totaled approximately $5 million. The net available borrowings under the Credit Facility as of December 31, 2005, were approximately $595 million. Interest on the outstanding borrowings under the Credit Facility is payable quarterly at a rate based on the bank agent's reference rate or, at the Company's election, at a rate based on LIBOR plus 55 basis points per annum. A facility fee equal to 15 basis points per annum is payable quarterly on the total amount available under the Credit Facility. The Company also has a $30 million demand line of credit (Short-Term Facility), which expires on December 12, 2006. Borrowings under the Short-Term Facility are based on LIBOR plus the applicable margin in effect under the Credit Facility. At December 31, 2005, there were no borrowings under the Short-Term Facility. At December 31, 2005, other borrowings included capital leases as well as debt at international locations maintained for working capital purposes. Interest is payable on the outstanding debt balances at the international locations at rates ranging from 2.3% to 7.7% per annum. There are two financial covenants that the Company is required to maintain in connection with the Credit Facility.

COMMON AND PREFERRED STOCK The Company issued 176 and 145 shares of restricted stock as compensation to key employees in 2005 and 2004, respectively. Of the 176 shares issued in 2005, 100 shares vest annually from one to four years after the grant date, while the remaining 76 shares contain a cliff vesting feature and vest four years after the grant date. Of the 145 shares issued in 2004, 115 shares vest annually from one to five years after the grant date, while the remaining 30 shares contain a cliff vesting feature with half vesting four years and the remaining half five years after the grant date. In 2000, the Company issued 525 shares of restricted stock as compensation to a key employee. These shares vested annually from one to five years after the grant date. All restricted shares carry dividend and voting rights, and the sale of the shares is restricted prior to the date of vesting. The restricted shares were recorded at their fair market value on the date of the grant, with a corresponding charge to shareholders' equity. The unearned portion is being amortized as compensation expense on a straight-line basis over the related vesting period. 32

BUSINESS SEGMENTS AND GEOGRAPHIC INFORMATION IDEX's operations have been aggregated (primarily on the basis of products, production processes, distribution methods and management organizations) into three reportable segments: Pump Products, Dispensing Equipment and Other Engineered Products. The Pump Products Group designs, produces and distributes a wide range of engineered industrial pumps, flow meters, compressors, injectors and valves, and related controls for process applications. The Dispensing Equipment Group designs, manufactures and markets precision-engineered equipment for dispensing, metering and mixing paints, and personal care products; refinishing equipment; and centralized lubrication systems. The Other Engineered Products Group designs, produces and distributes engineered equipment for industrial and commercial markets, including fire and rescue, transportation equipment, oil and gas, electronics, and communications. IDEX is not overly dependent on a single customer, the largest of which accounted for less than 2% of net sales for all years presented. Information on IDEX's business segments follows, and is based on the nature of products and services offered. The Company evaluates performance based on several factors, of which operating income is the primary financial measure. The accounting policies of the business segments are described in Note 1. Intersegment sales are accounted for at fair value as if the sales were to third parties. 2005 2004 2003 ---------- ---------- -------- NET SALES Pump Products External customers $ 616,475 $ 539,101 $453,703 Intersegment sales 4,198 3,235 2,813 ---------- ---------- -------- Total group sales 620,673 542,336 456,516 ---------- ---------- -------- Dispensing Equipment External customers 187,814 170,195 159,224 Intersegment sales -- 3 1 ---------- ---------- -------- Total group sales 187,814 170,198 159,225 ---------- ---------- -------- Other Engineered Products External customers 238,986 219,001 184,994 Intersegment sales 6 5 28 ---------- ---------- -------- Total group sales 238,992 219,006 185,022 ---------- ---------- -------- Intersegment eliminations (4,204) (3,243) (2,843) ---------- ---------- -------- Total net sales $1,043,275 $ 928,297 $797,920 ========== ========== ======== OPERATING INCOME(1) Pump Products $ 114,404 $ 93,356 $ 70,436 Dispensing Equipment 40,785 33,489 25,724 Other Engineered Products 56,682 47,120 32,990 Corporate office and other(2) (29,084) (24,581) (19,288) ---------- ---------- -------- Total operating income $ 182,787 $ 149,384 $109,862 ========== ========== ======== ASSETS Pump Products $ 707,614 $ 694,731 $551,183 Dispensing Equipment 205,333 214,140 203,786 Other Engineered Products 256,622 246,410 186,417 Corporate office and other(2) 74,611 31,011 19,353 ---------- ---------- -------- Total assets $1,244,180 $1,186,292 $960,739 ========== ========== ======== DEPRECIATION AND AMORTIZATION Pump Products $ 15,797 $ 16,464 $ 16,141 Dispensing Equipment 5,210 5,616 5,881 Other Engineered Products 5,696 6,012 5,116 Corporate office and other(3) 3,262 2,857 2,337 ---------- ---------- -------- Total depreciation and amortization $ 29,965 $ 30,949 $ 29,475 ========== ========== ======== CAPITAL EXPENDITURES Pump Products $ 13,758 $ 13,968 $ 12,887 Dispensing Equipment 3,824 2,769 2,967 Other Engineered Products 4,357 3,204 3,874 Corporate office and other 1,055 1,156 590 ---------- ---------- -------- Total capital expenditures $ 22,994 $ 21,097 $ 20,318 ========== ========== ======== (1) Group operating income excludes net unallocated corporate operating expenses.

IDEX CORPORATION 2005 ANNUAL REPORT Notes to Consolidated Financial Statements (continued) The assumptions used in the measurement of the Company's benefit obligation at December 31, 2005 and 2004, were as follows: U.S. Plans Non-U.S. Plans ----------- --------------------- 2005 2004 2005 2004 ---- ---- --------- --------- Discount rate 5.50% 5.75% 4.30-5.10% 5.50-6.00% Expected return on plan assets 8.50% 8.50% 5.00-5.90% 5.00-6.50% Rate of compensation increase 4.00% 4.00% 4.25% 4.25% To develop the expected rate of return on plan assets, the Company considered the historical returns and the future expectations for returns on each asset class, as well as the target asset allocation of the pension portfolio. The following tables provide the components of, and the assumptions used to determine, the net periodic benefit cost for the plans in 2005, 2004, and 2003: Pension Benefits Other Benefits --------------------------- ------------------------ 2005 2004 2003 2005 2004 2003 ------- ------- ------- ------ ------ ------ Service cost $ 4,854 $ 4,430 $ 3,765 $ 410 $ 413 $ 330 Interest cost 5,231 5,103 4,703 1,194 1,088 1,066 Expected return on plan assets (5,935) (5,597) (3,449) -- -- -- Net amortization 3,276 3,227 3,216 212 67 (31) ------- ------- ------- ------ ------ ------ Net periodic benefit cost $ 7,426 $ 7,163 $ 8,235 $1,816 $1,568 $1,365 ======= ======= ======= ====== ====== ====== U.S. Plans Non-U.S. Plans ------------------ ---------------------------- 2005 2004 2003 2005 2004 2003 ---- ---- ---- --------- --------- ---- Discount rate 5.75% 6.00% 6.75% 5.50-6.00% 5.50-6.00% 5.75% Expected return on plan assets 8.50% 8.50% 8.50% 5.00-6.25% 6.50% 6.50% Rate of compensation increase 4.00% 4.00% 4.00% 4.25% 4.25% 3.75% Prior service costs are amortized on a straight-line basis over the average remaining service period of active participants. Gains and losses in excess of 10% of the greater of the benefit obligation on the market value of assets are amortized over the average remaining service period of active participants. Costs of bargaining unit-sponsored multi-employer plans and defined contribution plans were $7,354, $6,404 and $6,756 for 2005, 2004 and 2003, respectively. For measurement purposes, a 9.5% annual rate of increase in the per capita cost of covered health care benefits was assumed for 2005. The rate was assumed to decrease gradually each year to a rate of 6% for 2013, and remain at that level thereafter. Assumed health care cost trend rates have a significant effect on the amounts reported for the health care plans. A 1% increase in the assumed health care cost trend rates would increase the service and interest cost components of the net periodic benefit cost by $103 and the health care component of the accumulated postretirement benefit obligation by $1,445. A 1% decrease in the assumed health care cost trend rate would decrease the service and interest cost components of the net periodic benefit cost by $89 and the health care component of the accumulated postretirement benefit obligation by $1,235. PLAN ASSETS The Company's pension plan weighted average asset allocations at December 31, 2005 and 2004, by asset category, were as follows: 2005 2004 ---- ---- Equity securities 64% 66% Debt securities 35 33 Other 1 1 --- --- Total 100% 100% === === 38

IDEX CORPORATION 2005 ANNUAL REPORT INVESTMENT POLICIES AND STRATEGIES The investment objectives of the Company's plan assets are to earn the highest possible rate of return consistent with the tolerance for risk as determined periodically by IDEX in its role as a fiduciary. The general guidelines of asset allocation of fund assets are that "equities" will represent from 55% to 75% of the market value of total fund assets with a target of 66%, and "fixed income" obligations, including cash, will represent from 25% to 45% with a target of 34%. The term "equities" includes common stock, convertible bonds and convertible stock. The term "fixed income" includes preferred stock and/or contractual payments with a specific maturity date. The Company strives to maintain asset allocations within the designated ranges by conducting periodic reviews of fund allocations and plan liquidity needs, and rebalancing the portfolio accordingly. The total fund performance is monitored and results measured using a 3- to 5-year moving average against long-term absolute and relative return objectives to meet actuarially determined forecasted benefit obligations. No restrictions are placed on the selection of individual investments by the qualified investment fund managers. The performance of the investment fund managers is reviewed on a regular basis, using appointed professional independent advisors. As of December 31, 2005 and 2004, there were no shares of the Company's stock held in plan assets. CASH FLOWS The Company expects to contribute approximately $6.0 million to its defined benefit plans, $7.0 million to its defined contribution plans and $1.0 million to its other postretirement benefit plans in 2006. ESTIMATED FUTURE BENEFIT PAYMENTS The future estimated benefit payments for the next five years and the five years thereafter are as follows: 2006--$9,327; 2007--$7,087; 2008--$5,536; 2009--$5,827; 2010--$6,234; 2011 to 2015--$45,149. 14.

Report of Independent Registered Public Accounting Firm To the Board of Directors and Shareholders of IDEX Corporation We have audited the accompanying consolidated balance sheets of IDEX Corporation and its subsidiaries (the Company) as of December 31, 2005 and 2004 and the related consolidated statements of operations, shareholders' equity, and cash flows for each of the three years in the period ended December 31, 2005. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of IDEX Corporation and its subsidiaries as of December 31, 2005 and 2004, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2005, in conformity with accounting principles generally accepted in the United States of America. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of the Company's internal control over financial reporting as of December 31, 2005, based on the criteria established in "Internal Control--Integrated Framework" issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 27, 2006 expressed an unqualified opinion on management's assessment of the effectiveness of the Company's internal control over financial reporting and an unqualified opinion on the effectiveness of the Company's internal control over financial reporting. /s/ Deloitte & Touche LLP - -------------------------- Deloitte & Touche LLP Chicago, Illinois February 27, 2006 40

Report of Independent Registered Public Accounting Firm To the Board of Directors and Shareholders of IDEX Corporation We have audited management's assessment, included in the accompanying Management's Report on Internal Control Over Financial Reporting, that IDEX Corporation and its subsidiaries (the Company) maintained effective internal control over financial reporting as of December 31, 2005, based on criteria established in "Internal Control--Integrated Frame work" issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on management's assessment and an opinion on the effectiveness of the Company's internal control over financial reporting based on our audit. We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an under standing of internal control over financial reporting, evaluating management's assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinions. A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements. Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. In our opinion, management's assessment that the Company maintained effective internal control over financial reporting as of December 31, 2005, is fairly stated, in all material respects, based on the criteria established in "Internal Control--Integrated Framework" issued by the Committee of Sponsoring Organizations of the Treadway Commission. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2005, based on the criteria established in "Internal Control--Integrated Framework" issued by the Committee of Sponsoring Organizations of the Treadway Commission. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of IDEX Corporation and its subsidiaries as of December 31, 2005 and 2004 and the related consolidated statements of operations, shareholders' equity, and cash flows for each of the three years in the period ended December 31, 2005, and our report dated February 27, 2006 expressed an unqualified opinion on those financial statements. /s/ Deloitte & Touche LLP - -------------------------- Deloitte & Touche LLP Chicago, Illinois February 27, 2006 41

IDEX CORPORATION 2005 ANNUAL REPORT Management's Report on Internal Control over Financial Reporting Internal control over financial reporting refers to the process designed by, or under the supervision of, our Chief Executive Officer and Chief Financial Officer, and effected by our board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles, and includes those policies and procedures that: Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company's assets that could have a material effect on the financial statements. Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives because of its inherent limitations. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Internal control over financial reporting also can be circumvented by collusion or improper management override. Because of such limitations, there is a risk that material misstatements may not be prevented or detected on a timely basis by internal control over financial reporting. However, these inherent limitations are known features of the financial reporting process. Therefore, it is possible to design into the process safeguards to reduce, though not eliminate, this risk. Management is responsible for establishing and maintaining effective internal control over financial reporting for the Company. Management has used the framework set forth in the report entitled "Internal Control--Integrated Framework" issued by the Committee of Sponsoring Organizations of the Treadway Commission to assess the effectiveness of the Company's internal control over financial reporting. Management has concluded that the Company's internal control over financial reporting was effective as of December 31, 2005. Deloitte & Touche LLP has issued an attestation report on management's assessment of the Company's internal control over financial reporting dated February 27, 2006. /s/ Lawrence D.
