Item 9B. Other Information.

On February 22, 2018, the Company entered into an amended and restated employment agreement with its Chief Executive Officer, Andrew K. Silvernail, effective as of February 22, 2018 (the “Employment Agreement”), replacing his previous employment agreement, dated February 19, 2016. The Employment Agreement provides for a term of approximately four years (expiring December 31, 2021).

Under the terms of the Employment Agreement, Mr. Silvernail will be entitled to the following: (i) an annual base salary of $1,000,000 subject to increase (but not decrease) in the discretion of the Board of Directors after an annual review; (ii) an annual incentive cash bonus under the IDEX Corporation Incentive Award Plan (the “IAP”) or other bonus plan as may be in

effect for senior executives and annual consideration for long-term equity awards under the IAP; and (iii) in addition to normal employee benefits offered to the Company’s officers, Mr. Silvernail will be permitted to use IDEX’s corporate aircraft for up to 25 hours of personal travel (as well as an additional 25 hours of use subject to reimbursement by Mr. Silvernail of the incremental costs for such additional hours of use) and will be provided with an automobile allowance in accordance with Company policy.

Under the terms of the Employment Agreement, if Mr. Silvernail’s employment is terminated by the Company other than for “cause” and not in connection with a “change in control” (each as defined in the Employment Agreement), then, subject to his execution and non-revocation of a general release of claims and his continued compliance with applicable restrictive covenants, he will receive (i) continuing salary payments and health benefits for 24 months following termination, (ii) a pro rata portion of his annual bonus for the year in which his termination occurs (based on the portion of the year he was employed), (iii) a payment equal to 200% of his base salary payable over 24 months commencing approximately 60 days after his termination, (iv) fully accelerated vesting and immediate exercisability of all unvested time-based equity awards (the “time-based acceleration”) with such time-based equity awards remaining exercisable for one year following the date of termination of his employment or until expiration of the option term, if earlier, (v) vesting of all unvested performance-based equity awards granted prior to February 22, 2018, on the December 31 following his termination of employment with respect to that number of shares of the Company’s common stock (or performance units or dividend equivalents, as applicable) based on the performance level achieved with respect to the performance goal(s) under each such award from the beginning date of the performance period applicable thereto through such December 31, and (vi) vesting of all unvested performance-based equity awards granted on or following February 22, 2018, at the end of the applicable performance period with respect to that number of shares of Company common stock (or performance units or dividend equivalents, as applicable) based on the performance level achieved through the end of such performance period ((v) and (vi), as applicable, the “performance-based acceleration”).

If Mr. Silvernail’s employment is terminated due to his disability or death, he or his estate, as applicable, will receive (i) a pro rata portion of his annual bonus for the year in which his termination occurs (based on the portion of the year he was employed), (ii) time-based acceleration, with such time-based awards granted before February 22, 2018, remaining exercisable for one year following the date of termination of employment or until expiration of the option term, if earlier, and those granted on or following February 22, 2018, remaining exercisable for five years following the date of termination of employment, or until expiration of the term, if earlier and (iii) performance-based acceleration.

If Mr. Silvernail’s employment is terminated due to his retirement, he will receive (i) the time-based acceleration, with such time-based awards granted before February 22, 2018, remaining exercisable for one year following the date of termination of employment or until expiration of the option term, if earlier, and with those granted on or following February 22, 2018, remaining exercisable for five years following the date of termination of employment or until expiration of the option term, if earlier and (ii) performance-based acceleration.

If Mr. Silvernail’s employment is terminated by the Company without cause or by him for “good reason” (as defined in the Employment Agreement), in either case, in contemplation of or within the 24 month period following a change in control, then, subject to his execution and non-revocation of a general release of claims and his continued compliance with applicable restrictive covenants, he will receive (i) continuing salary payments and health benefits for 36 months following termination, (ii) a pro rata portion of his annual bonus for the year in which his termination occurs (based on the portion of the year he was employed), (iii) a payment equal to 300% of his base salary, payable over 36 months commencing approximately 60 days after his termination, (iv) fully accelerated vesting and immediate exercisability of all unvested time-based equity awards and (v) in lieu of performance-based acceleration, a cash payment in respect of all performance-based equity awards with respect to which he has not yet received payment, based on the performance level achieved with respect to the performance goal(s) under each such award from the beginning date of the performance period applicable thereto through such change in control, with such cash payment adjusted to reflect hypothetical earnings (equal to the lesser of the Barclays Long Aaa US Corporate Index or 120% of the applicable federal long-term rate, in each case, determined as of the first business day of November of the calendar year preceding the change in control and compounded) for the period between such change in control and the date of payment.

In addition, to the extent that any payment or benefit received in connection with a change in control would be subject to an excise tax under Section 4999 of the Internal Revenue Code, such payments and/or benefits will be subject to a “best pay cap” reduction if such reduction would result in a greater net after-tax benefit to Mr. Silvernail than receiving the full amount of such payments. The Employment Agreement contains confidentiality covenants by Mr. Silvernail, which apply indefinitely.

The foregoing description of Mr. Silvernail’s Employment Agreement is qualified in its entirety by reference to its terms, which is filed as Exhibit 10.5 to this Form 10-K.
