Your annual base salary will be $240,000, payable on a biweekly basis at the rate of $9,230.77 per pay period. You will be eligible for a review of your salary with consideration for an increase in January 2009.

You will be eligible for participation in our Management Incentive Compensation Plan (MICP), which provides annual incentive earnings opportunity based on business unit and personal performance. You will be placed in Salary Range 22, which means your target level of incentive compensation will be 50% of your annual base pay in effect at the beginning of the plan year. The actual pay-out under the plan could be more or less than the target level and will depend on Gast’s performance and your performance. Enclosed is a copy of the IDEX MICP plan document.

You will be eligible for the full range of ChoiceComp benefits: IDEX Defined Contribution Retirement Plan, IDEX 401(k) Savings Plan, medical and dental coverage, short-term and long-term disability coverage, and life insurance. Summaries of these plans are enclosed. You will also be included in the IDEX Supplemental Executive Retirement Plan which provides restoration of retirement and 401(k) benefits beyond the qualified plan limitation set by the IRS.

You are eligible for a car allowance of $1,100 per month.

You will be eligible for three (3) weeks of vacation annually.

You will be eligible to participate in the IDEX Deferred Compensation Plan which provides an alternative to defer income and subsequent earnings on that income until after retirement.

Subject to approval from our Board of Directors, you will be eligible for equity grants in the form of a combination of stock options and restricted shares under the IDEX Incentive Award Plan at our annual grant in April. These annual awards are currently targeted at a value of 50% of base salary. This plan is designed to provide an incentive and reward to key employees who are in a position to make substantial contributions to the success of the company.

You will be eligible for select provisions of the IDEX moving policy, including reimbursement of realtor commissions and closing costs on the sale of your current Edwardsville, Illinois through our third-party home sale assistance provider under the Buyer Value Option (BVO), reimbursement of closing costs and fees involved in the purchase of a Toledo, Ohio-area home, and payment of household goods moving expenses.

You are eligible to enroll in the Executive Long Term Disability program which provides additional income in the case of total and permanent disability. This program is fully paid by IDEX.

In the event of a “Change in Control”, as defined in the Amended and Restated IDEX Corporation Supplemental Executive Retirement Plan, that results in your termination from service within twenty-four (24) months of the Change in Control, the Company shall be obligated to pay your base salary at the rate then in effect and your then current target annual bonus (MICP or equivalent pay) for a minimum of twenty-four (24) months following the date of termination (for a total payment of two (2) times both base salary and target annual bonus). This payment shall not be applicable in the event of your voluntary termination.

If, in the future, your employment with IDEX Corporation is terminated, without cause (“cause” defined as willful misconduct or fraudulent behavior), IDEX will pay you up to twelve (12) months base salary at the then current monthly base rate plus your targeted annual incentive bonus in exchange for a signed release. Such benefit will not be applicable in the event of your voluntary termination.
