R. Scott Rowe

Address on File

Dear Scott,

I am pleased to offer you the position of Chief Executive Officer of Flowserve Corporation, based in Irving, Texas. If you accept this position, we also expect to appoint you to be a member of the Flowserve Board of Directors on your start date.

Below you will find some important details about this job offer, including an overview of your compensation and benefits and general terms of employment.

Base Pay :

Your annual base salary will be $1,100,000, minus applicable taxes and withholdings. Flowserve currently pays wages on a bi-weekly basis (26 times per year), and your per pay period salary will be approximately $42,307.

Your Annual Incentive Pay Potential :

You are invited to participate in the Flowserve Corporation Annual Incentive Plan (“AIP”). Flowserve uses the AIP to reward employees for business success based on how well the company performs on key performance targets set at the beginning of each plan year.

Your target AIP award is 120% of your eligible earnings as defined in the AIP, a copy of which has been provided to you. This is the amount of incentive pay Flowserve expects you to earn in a given year if Flowserve’s and your individual performance objectives are met. The actual incentive amount paid may be more or less than the target based upon business and individual performance results. The maximum award you are eligible to receive (assuming objectives are exceeded) is 200% of the target award.

You will be eligible to participate in the 2017 AIP starting on your first date of employment. Any payment thereunder will be calculated based on your annual base salary (not pro-rated). Eligibility, benefits, payment, and administration of the AIP will follow the terms in the AIP document(s) including the Flowserve Equity and Incentive Compensation Plan and any subsequent amendments to those plans and documents (subject to the immediately preceding sentence).

Your Long-Term Incentive Pay Potential :

You are invited to participate in the Flowserve Corporation Long-Term Incentive Plan (LTIP). Your target long term incentive award is 500% of base salary and all equity grants will be subject to the terms of individual award agreements and the governing stock plan, except as provided below. For 2017, your LTIP grant is comprised of 50% restricted stock units and 50% performance share units under the Flowserve Corporation Equity and Incentive Compensation Plan. The 2017 restricted stock units vest one-third per year over a three-year period (except as provided below), with the vesting period commencing on your start date. The 2017 performance share units cliff vest at the end of the Plan’s three-year cycle, except as provided below. The number of 2017 performance share units that vest is determined by how well the company performed compared to the pre-determined LTIP targets. The maximum payment of performance share units at the end of the performance period is 200% of the target award.

Your 2017 grant will be issued in the first open trading window after your employment begins, and the number of restricted stock units and performance share units granted to you will be determined by using the average stock price of Flowserve stock for the last 20 trading days of the month preceding the grant date.

Grants under the LTIP are subject to approval by the Board of Directors, and your 2017 restricted stock units and 2017 performance share units have been so approved, subject to your acceptance of this offer of employment. Eligibility, benefits, payment, and administration of the LTIP will follow the terms in the stock agreements issued with each grant and the LTIP document(s) including the Flowserve Equity and Incentive Compensation Plan and any subsequent amendments to those plans and documents, except as provided below.

To encourage alignment between executive and shareholder interests, our executive compensation program requires all executives own a minimum amount of company common stock equal in value to a multiple of their respective annual base salaries. As Chief Executive Officer, you will be expected to hold stock equal in value to five times your annual base salary. The required stock ownership is expected to be achieved within five years from the date you join the Company, with interim retention requirements.

Stock Option Sign-On Bonus :

In the first open trading window after your employment begins, you will be granted a one-time stock option with a grant date fair value of $2,000,000 under the Flowserve Corporation Equity and Incentive Compensation Plan. This grant will cliff vest three years from your start date with the company except as provided below, and it will expire ten years after the grant date.

Acceleration of Vesting for 2017 Equity Grants if Terminated Without “Cause” :

With respect to the restricted stock units, performance share units and stock options granted to you in calendar year 2017 and notwithstanding anything to the contrary in the applicable stock agreements and plan documents, (i) “cause” shall be defined as such term is defined in the Flowserve Corporation Officer Severance Plan (“Severance Plan”) and (ii) in the event you are terminated without “cause” by the company prior to the third anniversary of your start date (or, in the case of the performance share units granted in calendar year 2017, prior to their vesting date) and subject to you executing and not revoking a release (in a form reasonably satisfactory
