Form of 2025 Performance Restricted Stock Unit Agreement for certain officers pursuant to the Flowserve Corporation 2020 Long-Term Incentive Plan

This Performance Restricted Stock Unit Agreement (this “Agreement”) is made and entered into by and between Flowserve Corporation, a New York corporation (the “Company”), and /$ParticipantName$/ (the “Participant”) as of /$GrantDate$/ (the “Date of Grant”). All capitalized terms used in this Agreement and not otherwise defined herein have the meanings given to such terms in the Plan (as defined below).

WHEREAS, the Company has adopted the Flowserve Corporation 2020 Long-Term Incentive Plan (as amended from time to time, the “Plan”) to strengthen the ability of the Company to retain the services of key Employees and Outside Directors and to increase the interest of such persons in the Company’s welfare.

WHEREAS, the Committee believes that the grant of Performance Restricted Stock Units to the Participant as described herein is consistent with the stated purposes for which the Plan was adopted.

NOW, THEREFORE, in consideration of the mutual covenants and conditions hereafter set forth and for other good and valuable consideration, the Company and the Participant agree as follows:

1. Performance Restricted Stock Units

(a) In order to encourage the Participant’s contribution to the successful performance of the Company, and in consideration of the covenants and promises of the Participant herein contained, the Company hereby grants to the Participant as of the Date of Grant, an Award of /$AwardsGranted$/ Restricted Stock Units subject to performance conditions (the “Performance Shares”), which will be converted into a number of shares of Common Stock of the Company equal to the number of vested Performance Shares or, as determined in the sole discretion of the Committee, into an equivalent amount of cash, subject to the conditions and restrictions set forth below and in the Plan. The Performance Shares granted hereunder shall constitute a Performance Award within the meaning of the Plan.

The Performance Shares will be earned based on the Company’s performance against the three performance metrics outlined below for the period beginning January 1, 2025, and ending December 31, 2027 (the “Performance Cycle”).

(a) Return on Invested Capital. One-half of the Performance Shares (the “ROIC Performance Shares”) will be earned based on the Company’s return on invested capital performance over each of the three calendar years of the Performance Cycle with such ROIC Performance Shares allocated evenly among each of the three years of the Performance Cycle (the “ROIC Performance Goals”), and subject to further adjustment as provided under Paragraph 2(c) below. The Committee has established the threshold, target and maximum ROIC Performance Goal for the first calendar year of the Performance Cycle, as set forth in Appendix A attached hereto. The Committee will establish and communicate to the Participant a threshold, target and maximum ROIC Performance Goal for the second and third calendar years of the Performance Cycle prior to March 30th of each such year, in accordance with the requirements of Section 6.7 of the Plan. Following the end of the Performance Cycle, the Committee shall compare the actual performance of the Company with the ROIC Performance Goals and certify, in writing, whether and to what extent the ROIC Performance Goals have been achieved for such Performance Cycle. Subject to the provisions of Paragraph 3 below, upon written certification by the Committee, which shall occur no later than March 15 of the year

following the year in which the Performance Cycle ends, as to whether, and to what extent, the ROIC Performance Goals have been achieved, the ROIC Performance Shares will become vested (the “Vesting Date”) and will be eligible for conversion in accordance with the following schedule, in each case, subject to further adjustment as provided under Paragraph 2(c) below:

(i) If the ROIC Performance Goal achieved is less than the threshold, the ROIC Performance Shares will not vest.

(ii) If the threshold ROIC Performance Goal is achieved, then 50% of the ROIC Performance Shares will vest.

(iii) If the target ROIC Performance Goal is achieved, then 100% of the ROIC Performance Shares will vest.

(iv) If the maximum ROIC Performance Goal is achieved or exceeded, then 200% of the ROIC Performance Shares will vest.

(v) If the ROIC Performance Goal achieved is between the threshold and the target, or between target and maximum, the number of ROIC Performance Shares that will vest will be interpolated on a straight-line basis between the two nearest designated points.

(b) Free Cash Flow. The remaining one-half of the Performance Shares (the “FCF Performance Shares”) will be earned based on the Company’s average annual free cash flow performance as a percentage of net income over each of the three calendar years in the Performance Cycle (the “FCF Performance Goals”), subject to further adjustment as provided under Paragraph 2(c) below. The Committee has established a threshold, target and maximum FCF Performance Goal for the 2025 calendar year, as set forth in Appendix A attached hereto. The Committee will establish and communicate to the Participant a threshold, target and maximum FCF Performance Goal for the 2026 and 2027 calendar years prior to March 30, 2026, and March 30, 2027, respectively, in accordance with the requirements of Section 6.7 of the Plan. Following the end of the Performance Cycle, the Committee shall compare the actual performance of the Company with the FCF Performance Goals and certify, in writing, whether and to what extent the FCF Performance Goals have been achieved for such Performance Cycle. Subject to the provisions of Paragraph 3 below, upon written certification by the Committee on the Vesting Date as to whether, and to what extent, the FCF Performance Goals have been achieved, the FCF Performance Shares will become vested on the Vesting Date and will be eligible for conversion in accordance with the following schedule, in each case, subject to further adjustment as provided under Paragraph 2(c) below:

(i) If the FCF Performance Goal achieved is less than the threshold, the FCF Performance Shares will not vest.

(ii) If the threshold FCF Performance Goal is achieved, then 50% of the FCF Performance Shares will vest.

(iii) If the target FCF Performance Goal is achieved, then 100% of the FCF Performance Shares will vest.

(iv) If the maximum FCF Performance Goal is achieved or exceeded, then 200% of the FCF Performance Shares will vest.

(v) If the FCF Performance Goal achieved is between the threshold and the target or between target and maximum, the number of FCF Performance Shares that will vest will be interpolated on a straight-line basis between the two nearest designated points.

(c) Relative Total Shareholder Return Modifier. ROIC Performance Shares and FCF Performance Shares which vest pursuant to the foregoing Paragraphs 2(a) and 2(b) shall be subject to adjustment in the aggregate based on the Company’s relative total shareholder return performance as compared to the total shareholder return performance of the constituent companies in a performance peer group over the Performance Cycle (“Relative TSR”). The Committee has established the Company’s performance peer

group for purposes of calculating the Relative TSR performance as set forth in Appendix A attached hereto. Subject to the provisions of Paragraph 3 below, upon written certification by the Committee on the Vesting Date as to whether, and to what extent, the Relative TSR has been achieved, the Performance Shares will become vested on the Vesting Date and will be eligible for conversion in accordance with the following schedule:

((i) If the Relative TSR achieved is at the 25th percentile or below, the aggregate percentage of Performance Shares that have vested pursuant to the foregoing Paragraphs 2(a) and 2(b) shall be reduced by 15% and such reduced amount shall be eligible for conversion.

(ii) If the Relative TSR achieved is above the 25th percentile and below the 45th percentile, the aggregate percentage of Performance Shares that have vested pursuant to the foregoing Paragraphs 2(a) and 2(b) shall be reduced by 7.5% and such reduced amount shall be eligible for conversion.

(iii) If the Relative TSR achieved is at or above the 45th percentile and below the 55th percentile, the aggregate percentage of Performance Shares that have vested pursuant to the foregoing Paragraphs 2(a) and 2(b) shall be neither reduced nor increased and such amount shall be eligible for conversion.

(iv) If the Relative TSR achieved is at or above the 55th percentile and below the 75th percentile, the aggregate percentage of Performance Shares that have vested pursuant to the foregoing Paragraphs 2(a) and 2(b) shall be increased by 7.5% and such increased amount shall be eligible for conversion. Notwithstanding the foregoing, if the Total Shareholder Return of the Company over the Performance Cycle is negative, the 7.5% increase shall not apply, and the aggregate percentage of Performance Shares that have vested pursuant to Paragraphs 2(a) and 2(b) shall be neither reduced nor increased and such amount shall be eligible for conversion.

(v) If the Relative TSR achieved is at the 75th percentile or higher, the aggregate percentage of Performance Shares that have vested pursuant to the foregoing Paragraphs 2(a) and 2(b) shall be increased by 15% and such increased amount shall be eligible for conversion. Notwithstanding the foregoing, if the Total Shareholder Return of the Company over the Performance Cycle is negative, the 15% increase shall not apply, and the aggregate percentage of Performance Shares that have vested pursuant to Paragraphs 2(a) and 2(b) shall be neither reduced nor increased and such amount shall be eligible for conversion.

(d) Except as otherwise provided in Paragraph 3 below, by no later than March 15 of the year following the year in which the Performance Cycle ends, the Company shall convert the vested Performance Shares into the number of whole shares, rounded up to the nearest whole share, of Common Stock equal to the number of vested Performance Shares, subject to the provisions of the Plan and the Agreement, or into a cash amount determined in accordance with Paragraph 2(g) below, and shall deliver such shares (in accordance with Paragraph 2(e) below) or cash to the Participant. The value of such shares of Common Stock shall not bear any interest owing to the passage of time.

(e) Following conversion of the vested Performance Shares into shares of Common Stock, such shares of Common Stock will be registered and transferred of record to the Participant. The delivery of any shares of Common Stock pursuant to this Agreement is subject to the provisions of Paragraphs 8 and 10 below.

(f) Each year that this Agreement is in effect, the Participant will receive credits (“Dividend Equivalents”) based upon the cash dividends that would have been paid on the number of shares of Common Stock equal to 100% of the Performance Shares as if such shares of Common Stock were actually held by the Participant. Dividend Equivalents shall be deemed to be reinvested in additional Performance Shares (which may thereafter accrue additional Dividend Equivalents). Any such reinvestment shall be at the Fair Market Value of the Common Stock at the time thereof. Dividend Equivalents may be settled in cash or shares of Common Stock, or any combination thereof, as determined by the Committee, in its sole and absolute discretion. The settlement of Dividend Equivalents in the form of shares of Common Stock will constitute a Bonus Stock Award for purposes of the Plan. Following conversion of the vested Performance Shares into shares of Common Stock, the Participant also shall receive a distribution of the Dividend Equivalents accrued with respect to such Performance Shares prior to the date of such conversion. In the

event any Performance Shares do not vest, the Participant shall forfeit his or her right to any Dividend Equivalents accrued with respect to such unvested Performance Shares.

(g) Notwithstanding the foregoing provisions of Paragraphs 2(e) and 2(f), the Committee may, in its sole and absolute discretion, in lieu of distributing any shares of Common Stock to the Participant, elect to pay the Participant an amount in cash equal to the Fair Market Value on the date of conversion of the shares of Common Stock that the Participant otherwise would be entitled to receive pursuant to this Agreement.

3. Effect of Termination of Service

(a) The Performance Shares granted pursuant to this Agreement shall vest in accordance with the provisions of Paragraphs 2(a)-2(c) above, on condition that the Participant does not experience a Termination of Service (i) for any reason other than “cause” (as determined by the Committee in its sole discretion) through the end of the Performance Cycle or (ii) for “cause” (as determined by the Committee in its sole discretion) at any time prior to the Vesting Date. If, however, the Participant experiences a Termination of Service, then, except as otherwise provided in Paragraphs 3(b) through 3(d) below, the Performance Shares that have not previously vested in accordance with the vesting schedule reflected in Paragraphs 2(a)-2(c) above, as of the date of such Termination of Service shall be forfeited by the Participant to the Company.

(b) Termination due to Death or Total and Permanent Disability. In the event the Participant experiences a Termination of Service due to his or her Total and Permanent Disability or death prior to the end of the Performance Cycle, then on the date of such Termination of Service (the “Death/Disability Vesting Date”), 100% of the outstanding Performance Shares shall vest as if the target Performance Goal has been achieved. Notwithstanding Paragraph 2(d) above, as soon as practicable, but in no event later than March 15 of the year following the year in which the Death/Disability Vesting Date occurs, the Company shall convert the vested Performance Shares into the number of whole shares of Common Stock equal to the number of vested Performance Shares, subject to the provisions of the Plan and this Agreement, or into a cash amount determined in accordance with Paragraph 2(g) above, and shall deliver such shares (in accordance with Paragraph 2(e) above) or cash to the Participant (or the Participant’s estate).

(c) Termination due to Special End of Service. In the event the Participant experiences a Termination of Service due to his or her Special End of Service prior to the end of the Performance Cycle, then the Performance Shares shall remain outstanding and on each remaining Vesting Date the Participant shall be entitled to receive the number of shares of Common Stock that would have been payable to such Participant if he or she had continued to provide services through the end of the Performance Cycle based on actual performance as determined by the Committee in accordance with Paragraph 2. For purposes of this Agreement, the term “Special End of Service” shall mean the voluntary termination of a Participant’s employment and other service with the Company for any reason other than due to the Participant’s death, Total and Permanent Disability or termination for “cause” (as determined by the Committee in its sole discretion) on or after (i) the date that is six months after the Date of Grant and (ii) attaining both (A) age 55 and (B) 10 years of service with the Company or its subsidiaries.

(a) Participant acknowledges that that he or she has become and will continue to become familiar with new and on-going Confidential Information (as defined below). Participant recognizes and agrees that: (i) the Company has devoted a considerable amount of time, effort and expense to develop its Confidential Information and business goodwill; (ii) the Confidential Information and the Company’s business goodwill are valuable assets to the Company; and (iii) any unauthorized use or disclosure of the Company’s Confidential Information would cause irreparable harm to the Company, including damage to the Company’s business goodwill, for which there is no adequate remedy at law. For these reasons, Participant agrees that, to protect the Company’s Confidential Information (as defined below) and business goodwill, it is necessary to enter into the following restrictive covenants. As used in this Paragraph 4, references to the “Company” refer to the Company and its Subsidiaries.

Participant, whether individually or as a principal, partner, stockholder, manager, agent, consultant, contractor, employee, lender, investor, volunteer, director or officer of any corporation or association or in any other manner or capacity whatsoever, agrees that during Participant’s employment by the Company and for a period of one (1) year following the date on which Participant’s employment ceases (for whatever reason) (the “Restricted Period”), Participant shall not, whether directly or indirectly, without the express prior written consent of the Company:

(I) Non-Solicitation. Other than for the benefit of the Company during Participant’s period of employment with or engagement by the Company, curtail the business of, interfere with the Company’s relationship with, solicit business from, attempt to transact business with or transact business with any customer or prospective customer of the Company with whom the Company transacted business or solicited within the preceding twenty-four (24) months, and which either: (A) Participant contacted, called on, serviced, did business with or had contact with during Participant’s employment or that Participant attempted to contact, call on, service, or do business with during Participant’s employment or engagement; (B) Participant became acquainted with or dealt with, for any reason, as a result of Participant’s employment or engagement by the Company; or (C) Participant received Confidential Information regarding during Participant’s employment with or engagement by the Company. This restriction applies only to business that is in the scope of services or products provided by the Company.

(II) Non-Recruitment. Recruit, solicit for employment, induce or encourage to leave the employment of or engagement by the Company, or otherwise cease their employment or engagement with the Company, on behalf of Participant or any other person or entity, any current employee or independent contractor of the Company or its subsidiaries (including those employees on vacation and approved leaves of absence, disability or other approved absence with the legal right to return to employment) or any former employee or independent contractor of the Company or its subsidiaries whose employment or engagement ceased no more than three (3) months earlier.

(III) Non-Competition. Become employed by, advise, perform services for, establish, have any ownership interest in, invest in or otherwise engage in any capacity, whether directly or indirectly, with a Competing Business in the Restricted Area. For purposes of this Agreement, “Competing Business” means any entity or business that is in the business of providing flow management products and related repair and/or replacement services. Because the scope and nature of the Company’s business is international in scope, the “Restricted Area” is worldwide. Nothing in this Paragraph 4(a)(III) shall prohibit the Participant’s direct or indirect ownership of securities of any business traded on any national securities exchange or an inter-dealer quotation system, on condition that: the Participant does not, directly or indirectly, own three percent (3%) or more of any class of securities of such business; such ownership is for investment purposes only; and the Participant does not have the right, and is not a member of a group that has the right, through the ownership of an equity interest, voting securities or otherwise, to direct the activities of such business.

For purposes of this Agreement, “Confidential Information” includes any trade secrets or confidential or proprietary information of the Company and its affiliates, including, but not limited to, the following:

(A) information concerning customers, clients, marketing, business and operational methods of the Company and its customers or clients, contracts, financial or other data, technical data, e-mail and other correspondence or any other confidential or proprietary information possessed, owned or used by the Company;

(B) business records, product construction, product specifications, financial information, audit processes, pricing, business strategies, marketing and promotional practices (including internet-related marketing) and management methods and information;

(C) financial data, strategies, systems, research, plans, reports, recommendations and conclusions;

(D) names, arrangements with, or other information relating to, any of the Company’s customers, clients, suppliers, financiers, owners, representatives and other persons who have business relationships with the Company or who are prospects for business relationships with the Company; and

(b) Non-Disclosure. The Participant shall not, during the period of the Participant’s employment or engagement by the Company or at any time thereafter, disclose, publish or use for any purpose any Confidential Information, except as: (i) required in the ordinary course of the Company’s business or the Participant’s work for the Company; (ii) required by law; or (iii) directed and authorized in writing by the Company. Upon the Participant’s Termination of Service for any reason and at any other time so requested by the Company, the Participant shall immediately return and deliver to the Company any and all Confidential Information, computers, hard drives, papers, books, records, documents, memoranda, manuals, e-mail, electronic or magnetic recordings or data, including all copies thereof, which belong to the Company or relate to the Company’s business and which are in the Participant’s possession, custody or control, whether prepared by the Participant or others. If at any time after the Participant’s Termination of Service, for any reason, the Participant determines that the Participant has any Confidential Information in the Participant’s possession or control, the Participant shall immediately return to the Company, or at the Company’s request destroy, all such Confidential Information in the Participant’s possession or control, including all copies and portions thereof. Participant shall provide the Company with written affirmation of the Participant’s compliance with the Participant’s obligations under this Paragraph 4(b) if so, requested by the Company. The Participant understands and agrees that the obligations under this Paragraph 4(b) are in addition to, and not in limitation or preemption of, all other obligations of confidentiality which the Participant may have to the Company under general legal or equitable principles, any other agreement with the Company or other policies implemented by the Company. Notwithstanding anything to the contrary contained herein, the Participant shall not be held criminally or civilly liable under any Federal or State trade secret law for the disclosure of a trade secret that is made in confidence to a Federal, State, or local government official, either directly or indirectly, or to an attorney; and solely for the purpose of reporting or investigating a suspected violation of law; or is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. If the Participant files a lawsuit for retaliation by Company for reporting a suspected violation of law, the Participant may disclose the trade secret to the Participant’s attorney and use the trade secret information in the court proceeding, if the Participant files any document containing the trade secret under seal, and does not disclose the trade secret, except pursuant to court order. In addition, nothing in this Agreement or any other outstanding award under the Plan or other agreement between the Company and the Participant prohibits disclosure or discussion of conduct the Participant reasonably believes to be unlawful, including illegal discrimination, illegal harassment, illegal retaliation, a wage-and-hour violation, or sexual assault or otherwise limits the Participant’s ability to communicate with the Securities and Exchange Commission or any other federal, state or local governmental agency or commission (each, a “Government Agency”) or otherwise participate in any investigation or proceeding that may be conducted by any Government Agency, including providing documents or other information and reporting possible violations of law or regulation or other disclosures

protected under the whistleblower provisions of applicable law or regulation, with or without notice to the Company, or from accepting any monetary award in connection therewith.

(c) Non-Disparagement. The Participant agrees that the Company’s goodwill and reputation are assets of great value to the Company which were obtained through great costs, time and effort. Therefore, the Participant agrees that during the Participant’s employment or engagement by the Company and at any time thereafter, the Participant will not in any way disparage, libel, defame, or make public statements or third-party disclosures, except to the extent required by law or legal proceedings or otherwise permitted under Paragraph 4(b) hereof, that are injurious to the Company, its business or business practices, its products or services or its employees.

(d) Remedies. The Participant acknowledges that the restrictions contained in this Paragraph 4, in view of the nature of the Company’s business, are reasonable and necessary to protect the Company’s legitimate business interests and business goodwill and that any violation of these restrictions would result in irreparable injury to the Company. The existence of any claim or cause of action by the Participant against the Company, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by the Company of the restrictive covenants contained in Paragraph 4.

(i) Forfeiture by the Participant. If the Participant breaches any restriction in this Paragraph 4, the Company shall be entitled to, in addition to any legal remedies available to the Company, undertake any or all of the following: (A) require the Participant to forfeit any Performance Shares (whether then vested or unvested) that have not yet been converted into Common Stock (or an equivalent cash payment) as of the date of such violation; (B) require the Participant to immediately sell to the Company a number of shares of Common Stock equal to the gross number of Performance Shares converted into Common Stock hereunder, for the then-current Fair Market Value of such shares; (C) require the Participant to immediately pay to the Company any cash settlement of Performance Shares hereunder or any gain that the Participant realized on any sale of shares of Common Stock issued in settlement of the Performance Shares granted hereunder; (D) discontinue future grants of any and all equity awards under any equity incentive plan in which the Participant may participate; (E) recover damages incurred by the Company as a result of the breach; and (F) recover its attorneys’ fees, costs and expenses incurred in connection with such actions. To the extent that the provisions of this Paragraph 4 are inconsistent with the terms of any other agreement between the Company and the Participant, the Company and the Participant agree that the provisions of this Paragraph 4 shall control.

(ii) Injunctive Relief and Damages. Participant acknowledges and agrees that a breach of Paragraph 4 will result in irreparable harm and continuing damage to the Company, and that money damages and the remedies set forth in Paragraph 4(d)(i) above would not be sufficient remedies to the Company for any such breach or threatened breach. Therefore, to the fullest extent permitted by law, Participant agrees that the Company shall also be entitled to a temporary restraining order and injunctive relief restraining Participant from the commission of any breach of Paragraph 4. Nothing contained in this Agreement shall be construed as prohibiting the Company from pursuing any other remedies available to it for any breach or threatened breach, including, without limitation, the remedies set forth in Paragraph 4(d)(i) or the recovery of money damages, attorneys’ fees and costs.

(e) Tolling. If Participant violates any of the restrictions contained in this Paragraph 4, the Restricted Period will be suspended and will not run in favor of Participant until such time that Participant cures the violation to the satisfaction of the Company.

5. Limitation of Rights

Nothing in this Agreement or the Plan shall be construed to:

(a) give the Participant any right to be awarded any further Performance Shares or any other Award in the future, even if Performance Shares or other Awards are granted on a regular or repeated basis, as grants of

Performance Shares and other Awards are completely voluntary and made solely in the discretion of the Committee;

(b) give the Participant or any other person any interest in any fund or in any specified asset or assets of the Company or any Subsidiary; or

(c) confer upon the Participant the right to continue in the employment or service of the Company or any Subsidiary, or affect the right of the Company or any Subsidiary to terminate the employment or service of the Participant at any time or for any reason.

6. Data Privacy

By execution of this Agreement, the Participant acknowledges that he or she has read and understands the Flowserve Corporation Employee Data Protection Policy and Flowserve’s Privacy Policy. The Participant hereby consents to the collection, processing, transmission, use and electronic and manual storage of his or her personal data by the Company, EQ Trust Company (“EQ Trust”) and Merrill Lynch & Co., Inc. (“Merrill Lynch”) in order to facilitate Plan administration. The Participant understands and acknowledges that this consent applies to all personally-identifiable data relevant to Plan administration, including the Participant’s name, home address, work email address, job title, GEMS ID, National Identification Number or Social Security Number, employee status, work location, work phone number, tax class, previous equity grant transaction data and compensation data. The Participant further agrees to furnish to the Company any additional information requested by the Company to enable it to comply with any reporting or other requirement imposed upon the Company by or under any applicable statute or regulation.

The Participant understands that for purposes of Plan administration, the Participant’s personal data will be collected and processed at 5215 N. O’Connor Blvd, 6th Floor, Irving, Texas (USA), and transferred to EQ Trust at 1110 Centre Pointe Curve, Suite 101, Mendota Heights, Minnesota (USA) and Merrill Lynch at 4 World Financial Center, 250 Vesey St., New York, New York (USA).

10. Securities Act

The Company will not be required to deliver any shares of Common Stock pursuant to this Agreement if, in the opinion of counsel for the Company, such issuance would violate the Securities Act of 1933, as amended (the “Securities Act”) or any other applicable federal or state securities laws or regulations. The Committee may require that the Participant, prior to the issuance of any such shares, sign and deliver to the Company a written statement, which shall be in a form and contain content acceptable to the Committee, in its sole discretion (“Investment Letter”):

When the Company is required to withhold any amount or amounts under the applicable provisions of any foreign, federal, state or local requirement or the Code, the Company shall withhold from the Common Stock to be issued to the Participant a number of shares necessary to satisfy the Company`s withholding obligations. The number of shares of Common Stock to be withheld shall be based upon the Fair Market Value of the shares on the date of withholding.

In the event any breach of this promise comes to the attention of the Company, it shall take into consideration that breach in determining whether to recommend the grant of any future similar award to the Participant, as a factor weighing against the advisability of granting any such future award to the Participant.

18. Amendments

Except as otherwise provided in the Plan or below, this Agreement may be amended only by a written agreement executed by the Company and the Participant. Notwithstanding the foregoing, the Board or the Committee may amend this Agreement to the extent necessary or advisable in light of any addition to or change in any federal or state, tax or securities law or other law or regulation, which change occurs after the Date of Grant and by its terms applies to the Award or to the extent that such amendment is not materially adverse to the Participant.

26. Insider Trading Restrictions/Market Abuse Laws.

The Participant may be subject to insider trading restrictions and/or market abuse laws based on the exchange on which the shares of Common Stock are listed and in applicable jurisdictions including the United States and the Participant’s country or his or her broker’s country, if different, which may affect the Participant’s ability to accept, acquire, sell or otherwise dispose of shares, Performance Shares or rights linked to the value of shares of Common Stock (e.g., Dividend Equivalents) during such times as the Participant is considered to have “inside information” regarding the Company (as defined by the laws in applicable jurisdictions).

regulations may prohibit the cancellation or amendment of orders the Participant placed before he or she possessed inside information. Furthermore, the Participant could be prohibited from (i) disclosing the inside information to any third party, which may include fellow employees and (ii) “tipping” third parties or causing them otherwise to buy or sell securities. Any restrictions under these laws or regulations are separate from and in addition to any restrictions that may be imposed under any applicable insider trading policy of the Company.

For greater certainty, "Continuous Service" shall be deemed to include any period constituting the minimum notice of termination period that is required to be provided to the Employee pursuant to the applicable employment standards legislation (if any), but shall exclude any other period, including any period of reasonable notice of termination at common law, that follows, or ought to have followed, the later of: (a) the end of the applicable minimum statutory notice period (if any); or (b) the Employee’s last day of actually and actively performing work for the Company or a Subsidiary;

selected unilaterally or by mutual agreement; (ii) an Employee of the Company or any Subsidiary suffers a Total and Permanent Disability; or (iii) an Outside Director of the Company or a Subsidiary ceases to serve as a director of the Company and its Subsidiaries for any reason. Except as may be necessary or desirable to comply with applicable federal, state or provincial law, a “Termination of Service” shall not be deemed to have occurred when a Participant who is an Employee becomes an Outside Director or vice versa.

Restrictive Covenants. Paragraph 4(a) of this Agreement shall be amended and replaced as follows:

Participant recognizes and agrees that: (i) the Company has devoted a considerable amount of time, effort and expense to develop its Confidential Information and business goodwill; (ii) the Confidential Information and the Company’s business goodwill are valuable assets to the Company; and (iii) any unauthorized use or disclosure of the Company’s Confidential Information would cause irreparable harm to the Company, including damage to the Company’s business goodwill, for which there is no adequate remedy at law. For these reasons, Participant agrees that, to protect the Company’s Confidential Information (as defined below) and business goodwill, it is necessary to enter into the following restrictive covenants. As used in this Paragraph 4, references to the “Company” refer to the Company and its Subsidiaries.

Participant, whether individually or as a principal, partner, stockholder, manager, agent, consultant, contractor, employee, lender, investor, volunteer, director or officer of any corporation or association or in any other manner or capacity whatsoever, agrees that during Participant’s employment by the Company and for a period of one (1) year following the date on which Participant’s employment ceases (for whatever reason) (the “Restricted Period”), Participant shall not, whether directly or indirectly, without the express prior written consent of the Company:

Nothing in this Paragraph 4(a)(III) shall prohibit the Participant’s direct or indirect ownership of securities of any business traded on any national securities exchange or an inter-dealer quotation system, on condition that: the Participant does not, directly or indirectly, own three percent (3%) or more of any class of securities of such business; such ownership is for investment purposes only; and the

Participant does not have the right, and is not a member of a group that has the right, through the ownership of an equity interest, voting securities or otherwise, to direct the activities of such business.

For purposes of this Agreement, “Confidential Information” includes any trade secrets or confidential or proprietary information of the Company and its affiliates, including, but not limited to, the following:

For absolute certainty, by accepting and executing this Agreement, the Participant specifically represents, warrants and acknowledges that the Participant has read and understood the Plan, this Agreement (including Appendices A, B and C), and including specifically Paragraph 4 (“Restrictive Covenants”) of this Agreement as amended by this Appendix B, Paragraph 27 (“Clawback”) of this Agreement, and Paragraph 3 (“Effect of Termination of Service”) of this Agreement along with the definitions of "Continuous Service" and “Termination of Service” of this Appendix B, which together: (i) have the effect that a Participant shall have no entitlement to damages or other compensation whatsoever arising from, in lieu of, or related to any Performance Shares which would have vested or been granted after their Termination of Service, including but not limited to damages in lieu of notice at common law; and (ii) have the effect that no period of contractual or common law reasonable notice that exceeds the Participant's minimum statutory notice period under applicable employment standards legislation (if any), shall be used for the purposes of calculating an Participant's entitlement under the Plan or this Agreement. By accepting and executing this Agreement, the Participant further waives any eligibility to receive damages or payment in lieu of any forfeited Performance Shares that would have vested or accrued during any contractual or common law reasonable notice period that exceeds a Participant's minimum statutory notice period under the applicable employment standards legislation (if any).

By accepting and executing this Agreement, the Participant represents, warrants and acknowledges:

(a)participation in the trade and acceptance of Performance Shares is voluntary;

(b)Performance Shares do not form an integral part of the Participant’s compensation from employment;

(c)they have not been induced to participate in the Plan by expectation of employment or continued employment with the Company or any Subsidiary;

(d)they have received, or have had the opportunity to receive independent legal advice in connection with the terms and conditions of this Agreement and the Plan (including the consequences in connection with the cessation of the Participant’s Continuous Service);

(e)the grant of Performance Shares does not create any contractual or other right or expectation to receive any additional grant(s) of Performance Shares or similar awards, or benefits in lieu of similar awards including without limitation during any common law period of reasonable notice of termination to which the Participant may be entitled, and even if they have been repeatedly awarded grants of Performance Shares;

(f)they understand that there is no promise of a particular monetary value associated with the vesting of any Performance Shares;

(g)the grant of Performance Shares is not compensation for services rendered and are an extraordinary item of compensation that is outside the scope of the Participant’s employment agreement with the Company or any Subsidiary, whether written or oral, and nothing can or must automatically be inferred from such the granting of such Performance Shares; and

(h)the Performance Shares will not be counted for any purpose including relating to the calculation of any overtime, severance, resignation, redundancy or end of service payments, or any long-service awards, bonuses, pension or retirement income or similar payments, and the Participant waives any claim on such basis.

The award of Performance Shares granted pursuant to the Agreement (the “Award”) is subject to the following additional terms and conditions to the extent that the Company, in its discretion, determines that the Participant’s participation in the Plan is subject to exchange control restrictions in the People’s Republic of China (“PRC” or “China”), as implemented by the State Administration of Foreign Exchange (“SAFE”), or other applicable laws of PRC.

Non-Competition Compensation.

Participant acknowledges and agrees that any non-competition compensation stipulated in the employment agreement (the “Employment Contract”) entered into between Participant, on the one hand, and the Company or any of its affiliates, on the other hand, shall constitute the entire consideration and compensation payable to Participant for his or her performance of the non-competition obligations under the Employment Contract and Paragraph 4 (Restrictive Covenants) of this Agreement, and the Company shall have no obligation to pay any additional compensation to Participant under this Agreement for Participant’s compliance with the restrictive covenants contained herein.

Modification of this Agreement. If any of the terms of this Agreement may in the opinion of the Company conflict or be inconsistent with any applicable PRC laws or regulations, the Company reserves the right to modify this Agreement to be consistent with applicable PRC laws or regulations.

Enforceability of this Agreement. It is expressly understood and agreed that although Participant and the Company consider the restrictions contained in Paragraph 4 (Restrictive Covenants) to be reasonable, if a judicial determination is made by a court in China that the time or territory or any other restriction contained in this Agreement is an unenforceable restriction against Participant, the provisions of this Agreement will not be rendered void, but will be deemed amended to apply as to such maximum time and territory and to such maximum extent as such court may judicially determine or indicate to be enforceable. Alternatively, if any court of competent jurisdiction in China finds that any restriction contained in this Agreement is unenforceable, and such restriction cannot be amended so as to make it enforceable, such finding will not affect the enforceability of any of the other restrictions contained in this Agreement.

Award Conditioned on Satisfaction of Regulatory Obligations. The Performance Shares are conditioned upon the Company securing and maintaining all necessary approvals from the SAFE and any other applicable government entities in the PRC to permit the operation of the Plan in China, as determined by the Company in its sole discretion.

Sale of Shares. Notwithstanding anything in the Plan to the contrary, when the Participant terminates employment with the Company or its affiliates, the Participant will be required to sell all Shares acquired under the Plan and any other equity incentive or purchase plan or program (collectively, “Equity Programs”) within such time period as may be established by the SAFE or otherwise within the later of six (6) months of such termination or of the final release of Shares underlying the Performance Shares, or other such period as may be required by Company policy, as determined in the Company’s discretion. If the Participant has not completed any required sale within the required period, then applicable, the Participant hereby authorizes the Company or any of its affiliates to complete such sale on the Participant’s behalf. The Participant agrees to sign any agreements, forms and/or consents that may be reasonably requested by the Company (or any of its affiliates or the Company’s designated brokerage firm) to effectuate the sale of the Shares (including, without limitation, as to the transfers of the proceeds and other exchange control matters noted below) and shall otherwise cooperate with the Company with respect to such matters. The Participant acknowledges that neither the Company nor the designated brokerage firm is under any obligation to arrange for such sale of the Shares at any particular price (it being understood that the sale will occur in the market), and that broker’s fees and similar expenses may be incurred in any such sale. In any event, when the Shares are sold, the sale proceeds, less any (mandatory) tax withholding, any broker’s fees or commissions, and any similar expenses of the sale will be remitted to the Participant in accordance with applicable exchange control laws and regulations and Company practices. The Participant acknowledges that any Award the Participant receives under the Equity Programs is taxable as per applicable PRC laws or regulations. The Participant accepts that paying personal income tax is the legal responsibility of the Participant and that the employer of the Participant has the obligation to withhold related personal income tax in China.

Exchange Control Restrictions. The Participant understands and agrees that the Participant will be required immediately to repatriate to China cash dividends (to the extent such dividends are not reinvested to purchase additional Shares, if such reinvestment is permitted by the SAFE and applicable laws) and the proceeds from the sale of any Shares acquired under the Equity Programs. The Participant further understands that such repatriation of dividends and proceeds may need to be affected through a special bank account established by the Company or its affiliate, and the Participant hereby consents and agrees that dividends and proceeds from the sale of Shares acquired under the Plan may be transferred to such account by the Company on the Participant’s behalf prior to being delivered to the Participant. The dividends and proceeds may be paid to the Participant in U.S. dollars or local currency, at the Company’s discretion. If the dividends and proceeds are paid to the Participant in U.S. dollars, the Participant understands that a U.S. dollar bank account in China must be established and maintained by the Participant so that the proceeds may be deposited into such account. If the dividends and proceeds are paid to the Participant in local currency, the Participant acknowledges that the Company is under no obligation to secure any particular exchange conversion rate and that the Company may face delays in converting the dividends and proceeds to local currency due to exchange control restrictions. The Participant agrees to bear any currency fluctuation risk between the time dividends are declared or the Shares are sold, and the dividends or net proceeds are converted into local currency and distributed to the Participant. The Participant further agrees to comply with any other requirements that may be imposed by the Company and its affiliates in the future in order to facilitate compliance with exchange control requirements in China and to sign any agreements, forms and/or consents that may be reasonably requested by the Company or its designated broker to effectuate any of the remittances, transfers, conversions or other processes affecting the proceeds.

Administration. The Participant shall be solely responsible for, and neither the Company nor its affiliates shall be liable for, any costs, fees, lost interest or dividends or other losses the Participant may incur or suffer resulting from the enforcement of the terms of this Appendix A or otherwise from the Company’s operation and enforcement of the Plan, the Agreement and the Performance Shares in accordance with Chinese law including, without limitation, any applicable SAFE rules, regulations and requirements.

Foreign Asset and Account Reporting Notification. If the Participant is a Chinese resident, the Participant may be required to report to SAFE all details of his or her foreign financial assets and liabilities, as well as details of any

economic transactions conducted with non-PRC residents. The Participant should consult with his or her personal tax advisor to determine the Participant’s personal reporting obligations.

Conversion from USD to CNY: The Participant’s proceeds will be converted from USD to CNY using the official rates as determined by HSBC on the date of payment. These CNY proceeds will be deposited into the Participant’s China Merchant Bank account. The Participant may elect to have proceeds paid in USD if the Participant is an account holder at HSBC. Please contact the Vice President, Total Rewards and HRIS to file or update optional payment instructions.

For the following, “French Participant” shall mean a Participant under the Plan who is, or is deemed to be, resident in France for the purpose of payment of income taxes or are otherwise liable to tax under the French Tax Code (Code Général des Impôts) in respect of its participation in the Plan.

French Language Consent. By signing and returning this Agreement, the French Participant confirms having read and understood the documents relating to the Plan which were provided to the Participant in English language. The French Participant accepts the terms of those documents accordingly and recognizes that those documents shall not be considered as amendments to the French Participant’s employment contract, and as such can be modified without his/her prior approval.

Labor Law Acknowledgment. In participating in the Plan, each French Participant acknowledges and agrees that:

(i)except if required by applicable employment standards legislation, any Award granted under the Plan shall not be considered to form an integral part of the French Participant’s compensation or considered to be normal or expected wages or salary for any purposes, including, but not limited to, for the calculation of any notice of termination of employment, payment in lieu of any notice of termination of employment, severance, resignation payment, termination payment, redundancy payment, expiry of fixed-term contract payment, dismissal payment, end of service payments, bonuses, holiday pay, paid time off, vacation pay, long-service awards, pension or retirement benefits or similar payments and in no event should be considered as compensation for, or relating in any way to, past services for the Company or its subsidiaries;

(ii)neither the Awards nor any provision of Plan or the policies adopted pursuant to the Plan confer upon any French Participant any right with respect to service or continuation of current service and shall not be interpreted to form an employment or a service contract or an amendment to the French Participant’s employment contract or relationship with the Company or its subsidiaries;

(iii)participation in the Plan by a French Participant is purely voluntary and the French Participant has not been induced to participate by expectation of engagement, appointment, employment or continued engagement, appointment or employment, as applicable.

Taxes. The Participant accepts any liability for any income tax, including any income withholding tax (prélèvement à la source), employee social security contributions (prélèvements sociaux) and employee share of any employment-related taxes including any social security contributions and charges which may be payable by the Company with respect to any taxable event arising pursuant to this Agreement (including the grant or vesting of the Performance Shares, Dividend Equivalents or the acquisition or disposal of any shares of Common Stock). The Participant shall pay to and indemnify the Company against and make arrangements satisfactory to the Company regarding payment of taxes mentioned above to the fullest extent permitted by applicable law and pursuant to Paragraph 11 of this Agreement.

By accepting this Award of Performance Shares, the Participant expressly acknowledges and agrees that this Award can be considered for purposes of calculating any applicable taxes that are statutorily required to be withheld by the Company or its subsidiaries.

The Plan is not intended to qualify for the application of the tax and social security treatment applicable to shares granted for no consideration under Articles L. 225-197-1 to L. 225-197-5 of the French Commercial Code, Article 80 quaterdecies of the French Tax Code and Articles L. 242-1, L. 137-13 and L. 137-14 of the French Social Security Code, as amended. In no event whatsoever a claim or entitlement to compensation or damages by the Company shall arise in connection with the non-application of such tax and social security treatment. Accordingly, under the standard French tax rules, the acquisition gain, equal to the fair market value of the Common Shares issued or the equivalent cash amount received by the participant, should be taxable as salary at the progressive income tax scale (with a maximum tax rate at 45%) and subject to social security contributions at the end of the vesting period.

Foreign Asset and Account Reporting Notification. The French Participant shall comply with tax reporting requirements as the result of the acquisition of Common Shares or cash derived from his participation in the Plan, in, to and/or from a brokerage/bank account or legal entity located outside of France. The French Participant acknowledges that he is responsible for ensuring compliance with the applicable foreign asset/account and tax reporting requirements and should consult his personal tax, legal and/or financial advisors regarding the same.

Exchange Control Notification. Cross-border payments in excess of a specified threshold (currently EUR 12,500) must be reported monthly to the German Federal Bank (Bundesbank). For payments made or received in connection with securities (including proceeds realized upon the sale of shares of Common Stock), the report must be filed electronically using the “General Statistics Reporting Portal” (“Allgemeines Meldeportal Statistik”) available via Bundesbank’s website (www.bundesbank.de). The Participant is personally responsible for complying with applicable exchange control requirements in Germany.

No Prospectus Requirements: Participation in the Plan is not offered to the public in Germany, and no action has been or will be taken which would allow an offering of participations in the Plan to the public in Germany. Participants in the Plan in Germany are exclusively employees of the Company or its affiliates, it being understood that such offer to employees to participate in the Plan is or shall be made to less than 150 non-qualified investors in each member state of the European Economic Area. The Plan, the discretionary Award of Performance Shares to a Participant and/or their vesting and subsequent settlement do not trigger any prospectus obligations in Germany. The granting of the Performance Shares to a Participant who is resident or employed in Germany does not constitute an “offer of securities to the public” within the meaning of article 2 lit. d) of the Regulation (EU) 2017/1129 of the European Parliament and of the Council of 14 June 2017 on the prospectus to be published when securities are offered to the public or admitted to trading on a regulated market, and repealing Directive 2003/71/EC (the “Prospectus Regulation”). In addition, no obligation to publish a prospectus would apply pursuant to either article 1 para. 4 lit. (i) or lit (b) of the Prospectus Regulation or any other provisions of German law.

These recipients may be located in the United States or elsewhere (including outside the European Economic Area). The recipients’ countries may have different data privacy laws and a lower level of data privacy protection standards than the Participant’s country of residence. The data transfer made to the Company in the United States is necessary for the conclusion and performance of the contract with the Participant. For subsequent transfers, the Participant will be enabled to explicitly consent to such transfers.

To the extent provided by law, the Participant has the right to (i) request access to, and a copy of, the Participant’s Personal Data as well as additional information about the processing and third party recipients of its Personal Data, (ii) request deletions, corrections or amendments to the Participant’s Personal Data, (iii) object to the processing of its Personal Data, withdraw the Participant’s consent, or request restrictions to the processing, (iv) ask for receiving, in a structured and standard format the Participant’s Personal Data, in each case without cost, by contacting local human resources representatives.

On any settlement or divestment of the Common Stock and/or reinvestment of proceeds from the sale of such Common Stock, Participant agrees to provide to the Indian Company in due time, true and accurate details regarding all such transactions, including amount of proceeds received and all supporting documenting evidencing such transactions (such as bank account statements or share certificates). It is hereby clarified that Participant also permits the Indian Company to disclose such information to an Authorized Dealer bank, Reserve Bank of India or any other regulatory authority, to comply with the Indian Company’s reporting obligations under the Indian laws (including FEMA).

Share Valuation. The amount subject to tax at vesting will partially be dependent upon a valuation that the Company will obtain from a Category I Merchant Banker in India. The Company has no responsibility or obligation to obtain the most favorable valuation possible nor obtain valuations more frequently than required under Indian tax law.

Data Privacy. You consent to the collection, use, disclosure and transfer, in electronic or other form, of your personal information (as such term is defined in the Information Technology Act, 2000 read with the Information Technology (Reasonable Security Practices and Procedures and Sensitive Personal Data or Information) Rules, 2011) as described in this document by and among, as applicable, the Indian Company, the Company and its Subsidiaries and affiliates for the exclusive purpose of implementing, administering and managing your participation in the Plan. You understand and consent to your personal information being transferred to any third parties assisting in the implementation, administration and management of the Plan, that these recipients may be located in India or elsewhere, in particular in the United States, and that the recipient country may have different data privacy laws providing less protections of your personal data than your country. You understand that refusing or withdrawing consent may affect your ability to participate in the Plan.

Taxation. At the time of vesting of the Stock Units, the Participant shall be liable to pay the difference between the Fair Market Value of such Stock Units and the exercise price. Such difference shall be treated as a perquisite and shall be included in the Participant’s income, subject to tax under the head “income from salary” as per the applicable provisions under the Income Tax Act, 1961. Upon the sale of such Stock Units, the gains arising from such sale shall be subject to capital gains tax. The classification of such capital gains as short-term or long-term shall be subject to the holding period and the capital gains tax shall be levied as per the applicable tax rates for short-term or long-term capital gains under the Income Tax Act, 1961. The Participant should consult with his or her personal tax advisor to determine the Participant’s personal reporting obligations.

Labor Law Acknowledgment. This provision supplements the acknowledgements contained in Paragraph 1 (Restricted Stock Units) of the Agreement:

In accepting the grant of Performance Shares, the Participant consents to participation in the Plan and acknowledges that the Participant has received a copy of the Plan.

This Agreement shall not be considered as an extension of the employment contract – if any – or of an obligation deriving from an employment contract. The Participant understands that the Company has unilaterally, gratuitously and in its own discretion decided to grant Performance Shares under the Plan to certain individuals who may be or not employees of the Company or an affiliate. The decision is a limited decision that is entered into upon the express assumption and condition that any grant will not bind the Company or an affiliate, other than as set forth in the Agreement. Consequently, the Participant understands that the Performance Shares are granted on the assumption and condition that the Performance Shares and any shares of Common Stock (“Shares”) acquired upon settlement of the Performance Shares are not a part of any employment contract (either with the Company or an affiliate) and shall not be considered a mandatory benefit, salary, nor salary components, for any purposes (including severance compensation), or any other right whatsoever. Further, the Participant understands that the Performance Shares would not be granted to the Participant but for the assumptions and conditions referred to above; thus, the Participant acknowledges and freely accepts that should any or all of the assumptions be mistaken, or should any of the conditions not be met for any reason, any grant of or right to the Performance Shares shall be null and void.

Cause. The parties agree that, when reference is made to termination for “Cause”, this shall be interpreted as termination for giusta causa under art. 2119 of the Italian civil code.

Non-competition. Paragraph 4(a)(III) shall be replaced as follows.

(III) Non-Competition. Perform activity in competition with that of the Company. It is hereby agreed that, for the purpose of such obligation, “Activity in Competition” refers to the performance of any activity in favour of companies, or even cooperative, bodies, organisations or any other entity that are in competition with the activity carried out by the Company at the termination of the employment contract. Particularly, “Activity in Competition” will be considered any activity in favour of companies and/or individuals that perform their activities within in the sector of manufacturing and aftermarket services for comprehensive flow control systems. This restrictive covenant prohibits any activity, even if different from the duties performed by the Participant during the employment agreement, in favour of the above mentioned entities, either directly or through a third party, or as a self-employed or as an employee, whether on occasional basis or for free, or as an associato in partecipazione or socio con prestazioni accessorie, or as a director or an institore, regardless of the job description of the future role performed. The non-competition covenant applies within the whole world. As consideration for all the above obligations, the Company shall pay the Participant a gross amount equivalent to the amount stated in the Participant’s employee agreement. If the obligations referred to in this clause are completely fulfilled, such amount will be paid, by deferred quarterly instalments, of the same amount each, starting from the employment contract termination date.

Nothing in this Paragraph 4(a)(III) shall prohibit the Participant’s direct or indirect ownership of securities of any business traded on any national securities exchange or an inter-dealer quotation system, on condition that: the Participant does not, directly or indirectly, own three percent or more of any class of securities of such business; such ownership is for investment purposes only; and the Participant does not have the right, and is not a member of a group that has the right, through the ownership of an equity interest, voting securities or otherwise, to direct the activities of such business.

Language Consent. By accepting the grant of Performance Shares, the Participant confirms having read and understood the Plan and Agreement which were provided in English.

Tax, taxes and tax withholding. References to tax, taxes and tax withholding in Paragraph 8. (Delivery of Shares), 11. (Federal and State Taxes) and 18. (Amendments) of the Agreement shall include social security contributions.

Governing law. Venue. With reference to Paragraph 19, it is understood that this paragraph will apply to the extent that it is compliant with Italian law.

Foreign Asset and Account Reporting Notification. If at any time during the fiscal year the Participant holds foreign financial assets (including bank accounts, cash and shares of Common Stock), the Participant may be required to

report these assets on his or her annual tax return (e.g., UNICO Form, PF Form, RW Schedule) for the year during which the assets are held, or on a special form if no tax return is due, irrespective of their value. These reporting obligations also will apply to Italian residents who are the beneficial owners of foreign financial assets under Italian money laundering provisions. The Participant should consult with his or her personal tax advisor to determine the Participant’s personal reporting obligations.

The Participant is eligible to an IVA benefit (Income Provision for Fully Disabled Persons) which is part of the WIA (Work and Income according to Labor Capacity Act).

“Involuntary termination” without cause shall be deemed to include entering into a termination agreement (in Dutch: ‘vaststellingsovereenkomst’) if the employer has initiated the termination, the employee cannot be held responsible for the necessity to terminate the employment agreement, and this is explicitly stated in the termination agreement.

“Termination for cause” shall have the following meaning.

“Termination for cause” includes the employer immediately terminating the employment contract due to seriously culpable behavior by the employee, as referred to in Articles 7:677 and 7:678 of the Dutch Civil Code (DCC), as well as termination by the competent court due to culpable acts or omissions by the employee, as outlined in Article 7:669 paragraph 1 sub e DCC. Examples include:

Securities Law Information. Any securities issued pursuant to the Plan (“Securities”) are issued pursuant to the “Qualifying Person” exemption” under section 273(1)(i) of the Securities and Futures Act 2001 of Singapore (“SFA”). No prospectus in connection with the Plan has been lodged or registered with the Monetary Authority of Singapore. Participant should note that the Securities are subject to section 257 of the SFA and Participant should not make any subsequent sale of Securities in Singapore or any offer of such subsequent sale of Securities in Singapore, unless such sale or offer in Singapore is made pursuant to the exemptions under Part XIII Division (1) Subdivision (4) (other than section 280) of the SFA.

Chief Executive Officer and Director Notification Requirement. If Participant is a chief executive officer (“CEO”) or director (including an alternate, substitute, or shadow director) of a Singapore Subsidiary, he or she is subject to certain notification requirements under the Companies Act 1967 of Singapore, regardless of whether he or she is a Singapore resident or employed in Singapore. Among these requirements is the obligation to notify the Singapore Subsidiary in writing when Participant receives or disposes of an interest (e.g., Performance Shares, Common Stock) in the Company or any related company. These notifications must be made within two (2) business days of (i) acquiring or disposing of any interest in the Company or any related company, or (ii) any change in a previously-disclosed interest (e.g., when Common Shares are subsequently sold). In addition, a notification must be made of his or her interests in the Company or any related company within two (2) business days of becoming a CEO or a director, associate director, or shadow director.

Insider Trading Information. Participant should be aware of the Singapore insider trading rules, which may impact the acquisition or disposal of Common Stock or rights to Common Stock under the Plan. Under the Singapore insider trading rules, you are prohibited from selling Common Stock when in possession of information which is not generally available and which you know or should know will have a material effect on the price of Common Stock once such information is generally available.

Vesting. Paragraph 2 (d) shall be replaced as follows.

(d) Except as otherwise provided in Paragraph 3 below, by no later than March 15 of the year following the year in which the Performance Cycle ends, the Company shall convert the vested Performance Shares into the number of whole shares, rounded up to the nearest whole share, of Common Stock equal to the number of vested Performance Shares, subject to the provisions of the Plan and the Agreement, or into a cash amount in accordance with the Plan which regulates the circumstances where conversion of vested Performance Shares in shares of common stock or cash amount will take place, and shall deliver such shares (in accordance with Paragraph 2(e) below) or cash to the Participant. The value of such shares of Common Stock shall not bear any interest owing to the passage of time.

Paragraph 2 (f) shall be replaced as follows.

(f) Each year that this Agreement is in effect, the Participant will receive credits (“Dividend Equivalents”) based upon the cash dividends that would have been paid on the number of shares of Common Stock equal to 100% of the Performance Shares as if such shares of Common Stock were actually held by the Participant. Dividend Equivalents shall be deemed to be reinvested in additional Performance Shares (which may thereafter accrue additional Dividend Equivalents). Any such reinvestment shall be at the Fair Market Value of the Common Stock at the time thereof. Dividend Equivalents will be settled in cash or shares of Common Stock, or any combination thereof, in accordance with the Plan which stipulates the circumstances where settlement in cash or settlement by shares of Common Stock or combination of both will take place. The settlement of Dividend Equivalents in the form of shares of Common Stock will constitute a Bonus Stock Award for purposes of the Plan. Following conversion of the vested Performance Shares into shares of Common Stock, the Participant also shall receive a distribution of the Dividend Equivalents accrued with respect to such Performance Shares prior to the date of such conversion. In the event any Performance Shares do not vest, the Participant shall forfeit his or her right to any Dividend Equivalents accrued with respect to such unvested Performance Shares.

Termination of Service. Paragraph 3 shall be replaced as follows:

(a) The Participant understands and agrees that, except in the case of Termination due to Death or Total and Permanent Disability covered in Paragraph 3(b) below, the Participant will forfeit any unvested Performance Shares as of the date Participant’s service ends without entitlement to the underlying Shares or to any amount of indemnification in the event of termination of Participant’s employment for any reason including, but not limited to, resignation, retirement, disciplinary dismissal adjudged to be with cause, disciplinary dismissal adjudged or recognized to be without cause (i.e., subject to a “despido improcedente”), individual or collective dismissal on objective grounds, whether adjudged or recognized to be with or without cause, material modification of the terms of employment under Article 41 of the Workers’ Statute, relocation under Article 40 of the Workers’ Statute, and/or

Article 50 of the Workers’ Statute, unilateral withdrawal by the Employer and under Article 10.3 of the Royal Decree 1382/1985.

(b) Termination due to Death or Total and Permanent Disability. In the event the Participant experiences a Termination of Service due to his or her Total and Permanent Disability or death, then on the date of such Termination of Service (the “Death/ Disability Vesting Date”), 100% of the Performance Shares shall vest. Notwithstanding Paragraph 2(b) above and subject to Paragraph 24, as soon as practicable, but in no event later than March 15 of the year following the year in which the Death/Disability Vesting Date occurs, the Company shall convert the vested Performance Shares into the number of whole shares of Common Stock equal to the number of vested Performance Shares, subject to the provisions of the Plan and this Agreement, and shall deliver such shares (in accordance with Paragraph 2(c) above) to the Participant (or the Participant’s estate).

Paragraph 4.d (i) shall be replaced as follows.

(i) Forfeiture by the Participant. If the Participant breaches any restriction in this Paragraph 4, the Company shall be entitled to, in addition to any legal remedies available to the Company, undertake any or all of the following: (A) require the Participant to forfeit any Performance Shares (whether then vested or unvested) that have not yet been converted into Common Stock as of the date of such violation; (B) discontinue future grants of any and all equity awards under any equity incentive plan in which the Participant may participate; and (C) recover damages incurred by the Company as a result of the breach. To the extent that the provisions of this Paragraph 4 are inconsistent with the terms of any other agreement between the Company and the Participant, the Company and the Participant agree that the provisions of this Paragraph 4 shall control.

Remedies. Paragraph 16 shall not apply to Participants located in Spain.

Labor Law Acknowledgment. This provision supplements the acknowledgements contained in Paragraph 1 (Restricted Stock Units) of the Agreement:

In accepting the grant of Performance Shares, the Participant consents to participation in the Plan and acknowledges that the Participant has received a copy of the Plan.

The Participant understands that the Company has unilaterally, gratuitously and in its own discretion decided to grant Performance Shares under the Plan to certain individuals who may be employees of the Company or an affiliate. The decision is a limited decision that is entered into upon the express assumption and condition that any grant will not bind the Company or an affiliate, other than as set forth in the Agreement. Consequently, the Participant understands that the Performance Shares are granted on the assumption and condition that the Performance Shares and any shares of Common Stock (“Shares”) acquired upon settlement of the Performance Shares are not a part of any employment contract (either with the Company or an affiliate) and shall not be considered a mandatory benefit, salary for any purposes (including severance compensation), or any other right whatsoever. Further, the Participant understands that the Performance Shares would not be granted to the Participant but for the assumptions and conditions referred to above; thus, the Participant acknowledges and freely accepts that should any or all of the assumptions be mistaken, or should any of the conditions not be met for any reason, any grant of or right to the Performance Shares shall be null and void.

Securities Law Notification. No “offer of securities to the public,” as defined under Spanish law, has taken place or will take place in the Spanish territory in connection with the grant of Performance Shares under the Plan. Neither the Plan nor the Agreement (which includes this Appendix A) have been, nor will they be registered with the Comisión Nacional del Mercado de Valores (Spanish securities regulator), and they do not constitute a public offering prospectus.

Exchange Control Notification. The Participant must declare the acquisition of Shares to the Dirección General de Comercial e Inversiones (the “DGCI”) of the Ministerio de Economia for statistical purposes. Generally, the declaration must be filed in January for Shares acquired or disposed of during the prior year and/or for Shares owned as of December 31 of the prior year; however, if the value of the Shares acquired under the Plan or the amount of the

sale proceeds exceeds a specified threshold (currently EUR 1,502,530), the declaration must be filed within one (1) month of the acquisition or disposition, as applicable.

The Participant also must declare electronically to the Bank of Spain any foreign securities accounts (including brokerage accounts held abroad), as well as the shares held in such accounts and transactions carried out with non-residents, depending on the amount of the transactions with non-residents during the relevant year or the balances/positions with non-residents. Different thresholds and deadlines to file the declarations apply. However, if neither such transactions during the immediately preceding year nor the balances/positions as of December 31 exceed a specified threshold (currently EUR one (1) million), no such declaration must be filed unless expressly required by the Bank of Spain. If neither the Participant’s total balances/positions nor total transactions with non-residents pertaining to the relevant period exceed a specified threshold (currently EUR 50 million), a summarized form of declaration may be used. The Participant is personally responsible for complying with applicable exchange control requirements in Spain.

Foreign Asset and Account Reporting Notification. Individuals owning shares deposited outside of Spain and/or holding bank accounts outside of Spain whose value as of December 31 each year, or at any time throughout the year of sale, exceeds, for each type of asset, a specified threshold (currently EUR 50,000), must report their existence to the Spanish Tax Authorities on a specific tax reporting form. After the assets have been reported, the subsequent reporting obligation will only apply if their value increases by more than specified amount (currently EUR 20,000) as of each subsequent December 31, or if the assets already declared are being transferred or the bank accounts are being closed. The Participant should consult with his or her personal tax advisor to determine whether this reporting requirement applies.

Additional Terms. The Award is granted to the Participant pursuant to the terms of the Flowserve Corporation 2020 Long-Term Incentive Plan UK Sub-Plan (“UK Sub-Plan”) and all references to the “Plan” in the Agreement and this Appendix A shall include a reference to the UK Sub-Plan.

Effect of Termination of Service. The term “Special End of Service” in Paragraph 3(c) shall be amended to mean the voluntary termination of a Participant’s employment with the Company or a Subsidiary for any reason other than due to the Participant’s death, Total and Permanent Disability, or termination for “cause” (as determined by the Committee in its sole discretion) on or after (i) the date that is six months after the Date of Grant and (ii) attaining both (A) 10 years of service with the Company or its subsidiaries and (B) the stated intention of leaving employment in the industry of the Company full-time.

Restrictive Covenants. The restrictions of Paragraphs 4(a)(I), 4(a)(II) and 4(a)(III) shall be replaced as follows:

Participant, whether individually or as a principal, partner, stockholder, manager, agent, consultant, contractor, employee, lender, investor, volunteer, director or officer of any corporation or association or in any other manner or capacity whatsoever, agrees that during Participant’s employment by the Company and for a period of one (1) year following the earlier of the : (i) date on which Participant’s employment ceases (for whatever reason); or (ii) the date the Participant commences a period of garden leave immediately prior to the date on which the Participant’s employment ceases (each “Termination”) (the “Restricted Period”), Participant shall not, whether directly or indirectly, without the express prior written consent of the Company:

(i)Non-Solicitation. Other than for the benefit of the Company during Participant’s period of employment with or engagement by the Company, curtail the business of, interfere with the Company’s relationship with, solicit business from, attempt to transact business with or transact business with any customer or prospective customer of the Company with whom the Company transacted business or solicited within the preceding twelve (12) months prior to Termination (“Relevant Period”), and which either: (A) Participant materially contacted, called on, serviced, did business with or had material or personal contact with during the Relevant Period; (B) Participant became materially or personally acquainted with or materially dealt with, for any reason, during the Relevant Period and as a result of Participant’s employment by the Company; or (C) Participant received Confidential Information regarding during the Relevant Period.

Because the scope and nature of the Company’s business is international in scope, the “Restricted Area” is the United Kingdom and such other countries within which the Company conducted Competing Business in the Relevant Period. Nothing in this Paragraph 4(a)(III) shall prohibit the Participant’s direct or indirect ownership of securities of any business traded on any national securities exchange or an inter-dealer quotation system, on condition that: the Participant does not, directly or indirectly, own three percent (3%) or more of any class of securities of such business; such ownership is for investment purposes only; and the Participant does not have the right, and is not a member of a group that has the right, through the ownership of an equity interest, voting securities or otherwise, to direct the activities of such business.

Data Privacy. For the purposes of administering the Plan and UK Sub-Plan, the Company will collect and process information relating to the Participant in accordance with the Employee Privacy Notice, which is available at Flowserve Ethics Hotline, and which supplements the Flowserve Corporation Employee Data Protection Policy and Flowserve’s Privacy Policy and replaces and supersedes the consent provided for under the second and third sentence of Paragraph 6 (Privacy).

(e) As a condition of the grant of the Performance Shares and the Dividend Equivalents, and to the fullest extent permitted by applicable law, the Participant agrees to accept any liability for secondary Class 1 National Insurance Contributions (the “Employer NICs”) which may be payable by the Company or the Employer with respect to the vesting of the Performance Shares and the settlement of the Dividend Equivalents or otherwise payable with respect to a benefit derived in connection with the Performance Shares or the Dividend Equivalents.

The Participant further agrees to execute such other joint elections as may be required between the Participant and any successor to the Company and/or the Employer. If the Participant does not enter into a Joint Election, no shares of Common Stock shall be issued to the Participant without any liability to the Company and/or the Employer.

The Participant further agrees that the Company and/or the Employer may collect the Employer NICs from the Participant by any of the means set forth in Paragraph 11 of this Agreement.

(f) The Participant acknowledges that the Participant is ultimately liable and responsible for all Tax Liability arising in connection with the Performance Shares and the Dividend Equivalents, regardless of any action the Company or any Subsidiary takes with respect to any tax withholding obligations that arise in connection with the Performance Shares or the Dividend Equivalents, and regardless of the way such Award is settled. Neither the Company nor any Subsidiary makes any representation or undertaking regarding the treatment of any tax withholding in connection with the awarding, vesting or payment of the Performance Shares or the Dividend Equivalents or any subsequent sale of the shares of Common Stock. The Company and the Subsidiaries do not commit and are under no obligation to structure the Performance Shares or the Dividend Equivalents to reduce or eliminate the Participant’s Tax Liability.
