This Service Agreement (“Agreement”), executed on this 4th day of May, 2021 (the “Effective Date”), by and between IPG Laser GmbH, a German limited liability company having an office at Xxxxxxxxxxxxxx 0, X-00000 Xxxxxxx, Xxxxxxx (the “Company”), and Xxxxxx Xxxxxxxxxx (“Executive”). The Company and Executive are referred to jointly below as the “Parties.”

WHEREAS, the Company and Executive previously entered into a restated service agreement dated May 30, 2019 (the “Prior Agreement”);

WHEREAS, the Company and Executive desire to amend and restate the Prior Agreement; and

WHEREAS, the Company desires to continue to retain Executive and Executive desires to continue his services on the terms and conditions set forth in this Agreement.

NOW, THEREFORE, in consideration of the services to be provided by Executive, the mutual terms and conditions set forth below, and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Parties agree as follows:

1. Service. Executive will provide service to the Company in the position of Geschaftsfuhrer and, pursuant to that Secondment Agreement dated 4 May, 2021 will provide service as Chief Executive Officer of IPG Photonics Corporation (“Parent”). Executive will report to the Company’s sole shareholder and to Parent’s Board of Directors (the “Board”). Executive’s primary responsibility will be managing the general business and affairs of the Company and performing related administrative duties, and executing Chief Executive Officer management responsibilities for Parent. Executive will carry such duties as shall be assigned from time to time by the Company’s sole shareholder and Parent’s Board, subject to applicable laws, and ethical duties. During the Term (as defined below), Executive shall devote Executive’s reasonable best efforts, energies and abilities and Executive’s full business time, skill and attention to the business and affairs of Parent and its Affiliates (as defined below), and shall act at all times according to the highest professional standards, for the purpose of advancing the business of Parent and its Affiliates. For purposes of this Agreement, an “Affiliate” shall mean a corporation that, for purposes of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), is a Parent or Subsidiary of the Company within the meaning of Code Sections 424(e) and 424(f).

2. Term. This Agreement shall commence on the Effective Date and shall expire on 12:00 pm E.S.T. on December 31, 2022 (the “Initial Term”), unless terminated earlier pursuant to the provisions of Sections 6, 7, 8, or 9 hereof. The term of service shall be renewed automatically for successive periods of one (1) year each (a “Renewal Term”) after the expiration of the Initial Term, unless the Company provides Executive, or Executive provides the Company, with written notice to the contrary at least one hundred eighty (180) days prior to the end of the Initial Term or any Renewal Term. The Initial Term and any Renewal Terms are collectively referred to herein as the “Term.” If either the Company or Executive elect not to

renew the Term of this Agreement in accordance with this Section 2 and Executive thereafter continues to provide services to the Company or its Affiliates, Executive shall be retained on an at-will basis and the terms of such service and any subsequent termination of service shall be subject solely to the Company’s general practices and policies. In the event of a “Change in Control” of the Company (as such term is defined in the IPG Photonics Corporation 2006 Incentive Compensation Plan, as amended (the “Equity Plan”)) during the Term, the Term automatically will be extended until the later of (i) the second anniversary of the Change in Control, or (ii) the scheduled expiration of the then-current Term.

3. Compensation.

(i) Salary. The Company shall pay to Executive a salary at a monthly rate of €51,779 on the basis of a 14-month year for a gross annual base salary (“Base Salary”) of Five Hundred, Fifty Thousand, Nine Hundred Euros (€724,900) effective as of the Effective Date. The Company will pay Executive’s Base Salary in equal installments in accordance with the Company’s standard payroll policies and schedule, subject to tax and elective withholding and deductions. Thereafter, the Board, or such committee of the Board as is responsible for setting the compensation of senior executive officers, shall review Executive’s performance and Base Salary annually in January of each year, in light of competitive data, the Company’s performance, and Executive’s performance, and such other factors as the Board deems appropriate, and determine whether to adjust Executive’s Base Salary, retroactive to January 1 of the year. The first review shall be in February 2022. Such adjusted annual salary then shall become Executive’s Base Salary for purposes of this Agreement.

(ii) Annual Bonus. Executive will be eligible for an annual cash bonus (the “Bonus”), based on performance, and calculated as a percentage of Executive’s Base Salary. The Bonus will be paid at the time payment is made to other similarly-situated executives of the Company, but in no event later than two and a half of the close of the calendar year in which Executive’s right to the Bonus is no longer subject to a substantial risk of forfeiture.

(iii) Equity Compensation. Executive will be eligible to participate in any long-term incentive plans, and/or equity-based compensation plans established or maintained by the Company’s shareholder for its senior executive officers or employees, including, but not limited to, the Equity Plan.

4. Benefits.

(i) Executive shall be entitled to the extent eligible to participate in any benefit plans as may be adopted and modified by the Company from time to time, including without limitation health, dental and medical plans, life and disability insurance, paid vacation, holiday, and retirement plans. The benefits available to Executive shall be no less favorable than those available to other executives at similar levels within the organization or to the employees of the Company at the location where Executive works. Benefits provided under this Agreement shall be subject to the terms and conditions of any applicable benefit plan, including any eligibility and vesting

requirements, as such plans may be in effect from time to time, and to Parent’s and its affiliates’ ability to amend, modify, or terminate such plan(s) at any time and from time to time.

(ii) Executive shall be entitled to five weeks of paid vacation each year. The maximum number of accrued vacation hours that Executive can have at any point in time is equal to the total vacation hours earned in the last twelve (12) months, plus one week of vacation carried over from the prior twelve (12) months of service.

(iii) Executive shall have the right to a luxury class car which may be also used for personal purposes.

5. Other Activities. The retention of Executive shall be on a full-time basis, but Executive may be an investor or otherwise have an interest in or serve on the board of directors or advisory board to other businesses, partnerships and entities so long as the other activities of Executive (a) do not materially interfere with the performance of Executive’s duties to the Company, (b) violate the other provisions of either this agreement or the Company’s Code of Conduct, or (c) cause Executive to violate the Restrictive Covenant Agreement defined and incorporated herein in Section 12 of this Agreement and Executive discloses all such activities to the Chair of Parent’s Compensation Committee of the Board in writing, provided that, Executive may not serve on the board of directors of a private or publicly traded company (other than Parent or a not-for-profit organization) without the Compensation Committee’s written consent and Executive may not serve as chairman of another publicly traded company without the Board’s written consent. Nothing in this provision or this Agreement limits or restricts Executive’s duties and obligations, including the duty of loyalty, that arise under the law.

6. Termination by the Company. The Company may terminate Executive’s service during the Term:

(i) without Cause (as defined below) by giving Executive thirty (30) calendar days’ prior written notice, or

(ii) for Cause (as defined below) by delivering to Executive a copy of a resolution duly adopted by the affirmative vote of a majority of the independent directors of the Board then in office at a meeting of the Board called and held for such purpose, finding that, Executive has committed an act or omission set forth below in this Section 6. Nothing herein shall limit Executive’s right or Executive’s beneficiaries’ right to contest the validity or propriety of any such determination, in accordance with Section 23 of this Agreement. For purposes of this Agreement, “Cause” shall mean: (A) an act of fraud, embezzlement or theft by Executive in connection with Executive’s duties or in the course of Executive’s service to the Company or an Affiliate; (B) Executive’s intentional wrongful damage to the property of the Company or its Affiliates; (C) Executive’s intentional breach of Section 12 hereof while Executive remains in the employ of the Company or an Affiliate; (D) an act of Gross Misconduct (as defined below); (E) Executive’s material violation of Parent’s Code of Conduct, as amended from time to time; or (F) Executive’s conviction of a misdemeanor involving moral turpitude or a felony; and, in each case, the reasonable, good faith determination by the Board as

hereafter provided that any such act or omission shall have been materially harmful to Parent or an Affiliate financially, reputationally or otherwise. For purposes of this Agreement, “Gross Misconduct” shall mean a willful or grossly negligent act or omission that has or will have a material and adverse impact on the business or reputation of Parent or its Affiliates, or on the business of the customers or suppliers of Parent or its Affiliates as such relate to Parent. For purposes of this Agreement, no act or failure to act on Executive’s part shall be considered willful unless it is done, or omitted to be done, by Executive in bad faith or without reasonable belief that Executive’s action or omission was in the best interests of Parent or an Affiliate. Any act or failure to act based upon authority given pursuant to a resolution duly adopted by the Board or based upon the advice of counsel for Parent or an Affiliate shall be conclusively presumed to be done, or omitted to be done, in good faith and in the best interests of Parent or an Affiliate. In addition, Executive’s service shall be deemed to have terminated for Cause if, based on facts and circumstances discovered after Executive’s service has terminated, the Board of Parent determines in reasonable good faith, within one year after Executive’s service terminated, and after appropriate investigation and an opportunity for Executive to be interviewed (with or without counsel as Executive may determine) by a subcommittee of the independent Board members or its representative, that Executive committed an act during the Term that would have justified a termination for Cause.

7. Termination by Executive. Executive may terminate his service during the Term by giving the Company sixty (60) calendar days’ prior written notice; provided that, if Executive purports to terminate his service during the Term for Good Reason (as defined below), Executive must give the Company written notice of Executive’s intent to terminate for Good Reason within sixty (60) days of the occurrence of the event that allegedly constitutes Good Reason. The Company shall have a right to cure the event alleged to constitute Good Reason for a period of thirty (30) calendar days after notice from Executive of intention to terminate for Good Reason. In the event of termination by notice under the first sentence of this Section 7, the Company in its discretion may elect a termination date that is earlier than the conclusion of the sixty (60) calendar day notice period, but the termination shall still be deemed a voluntary termination by Executive with Good Reason under this Section. “Good Reason” means the occurrence of any of the following events without Executive’s express written consent:

(i) The material reduction of Executive’s authorities, duties, or responsibilities with the Company;

(ii) A material reduction by the Company of Executive’s Base Salary, other than a reduction approved by the Board that similarly applies to all executive officers of the Company, provided that such a reduction in Base Salary shall not exceed more than twenty percent (20%) of Executive’s then Base Salary;

(iii) A relocation of the offices of Executive to a place greater than (A) fifty (50) miles in distance from the current executive offices of the Company in Oxford, MA, and (B) the current distance of Executive’s commute from Executive’s home residence to the current executive offices of the Company in Burbach, Germany; or

(iv) Any action or inaction that constitutes a material breach by the Company of this Agreement.

The Company shall have no obligations to Executive after Executive’s last day of service following termination of service under this Section, except as specifically set forth in this Agreement or under any applicable plans, programs or arrangements of the Company including, without limitation, its Articles of Association or similar organizational documents, or Parent’s Certificate of Incorporation or By-Laws, as either may be amended from time to time, the Equity Plan and any agreements thereunder, and the indemnification agreement described in Section 14.

8. Automatic Termination. Notwithstanding the provisions of Section 2, Executive’s service shall automatically terminate upon Executive’s death or Disability (as defined below). Executive shall be deemed to have a “Disability” for purposes of this Agreement if Executive is unable to perform substantially, by reason of physical or mental incapacity, Executive’s duties or obligations under this Agreement, with or without reasonable accommodation as defined in the Americans with Disabilities Act and implementing regulations, for a period of one hundred and eighty (180) consecutive calendar days in any 360-calendar day period. The Board shall determine, in the good faith exercise of its reasonable discretion, according to the facts then available, whether and when the Disability of Executive has occurred.

9. Term of Agreement. Any termination of Executive’s service shall also end the Term. For purposes of this Agreement, Executive’s service with the Company and its Affiliates shall be deemed to be terminated when Executive has a “separation from service” within the meaning of Code Section 409A, and references in this Agreement to termination of service shall be deemed to refer to such a separation from service. Upon Executive’s separation from service for any reason, Executive shall be deemed to have resigned as of the date of Executive’s separation from service from all offices, directorships and fiduciary positions with the Company, its Affiliates, and employee benefit plans of the Company and its Affiliates unless Executive is affirmatively re-appointed or re-elected to such position as of the date of Executive’s separation from service.

10. Certain Obligations of the Company Following Termination of Executive’s Service. Following termination of Executive’s service during the Term under the circumstances described below, the Company will pay to Executive the following compensation and provide the following benefits in addition to any benefits to which Executive may be entitled by law in full satisfaction and final settlement of any and all claims and demands that Executive or the Company may have against the other under this Agreement:

(i) Termination of Service for Any Reason. In the event of Executive’s termination of service for any reason, the Company shall pay or provide Executive (a) any unpaid Base Salary through the date of termination and (b) any benefits (including, without limitation, any unused vacation accrued in accordance with Section 4(ii)) accrued, earned or vested, and any unreimbursed expenses incurred, up to and including the effective date of such termination to which Executive may be entitled under the terms of any applicable arrangement, plan or program (collectively, the “Accrued Amounts”).

(ii) Without Cause by the Company or for Good Reason by Executive. If, during the Term, the Company terminates Executive’s service without Cause under Section 6(i) hereof or Executive terminates his service for Good Reason under Section 7 hereof, Executive shall be entitled to the following payments and benefits, subject to Section 13:

(a) The Accrued Amounts, as soon as reasonably practicable following the date of termination;

(b) Any Bonus that has been actually earned as of or prior to the termination date, but has not been paid, payable at the time payment is made to other similarly-situated executives of Company or its Affiliates, but in no event later than two and a half (2½) months after the close of the calendar year in which Executive’s right to the Bonus is no longer subject to a substantial risk of forfeiture;

(c) A pro rata portion of the amount of Bonus, if any, Executive would have received pursuant to Section 3(ii) for the year in which Executive’s service terminated. The Company shall determine what annual Bonus, if any, Executive would have earned had he been providing services through the end of the applicable period (the “Base Incentive Amount”), in accordance with the methods used to calculate the annual Bonus for the Company’s other similarly-situated executives; provided that, with respect to the personal performance evaluation element of the annual Bonus calculation, if all financial metric components meet or exceed the “target” level of performance, Executive shall be deemed awarded one hundred percent (100%) of the potential personal performance evaluation bonus; if no financial metric bonus is awarded, no personal performance evaluation bonus will be deemed awarded, and amounts in between the threshold, target and maximum levels of performance will be determined by linear interpolation. The pro rata portion to be paid pursuant to this paragraph shall be determined by multiplying the Base Incentive Amount by a fraction, the numerator of which is the number of calendar days from the beginning of the applicable annual period in which the termination occurred through the date of termination and the denominator of which is 365. Any payment due under this paragraph shall be paid at the time payment is made to other similarly-situated executives of the Company, but in no event later than two and a half (2½) months after the close of the calendar year in which Executive would have become vested in such Bonus;

(d) Continuing payments of Base Salary, payable in accordance with regular payroll practices of the Company, for eighteen (18) months following the date of termination; and

of coverage. The foregoing notwithstanding, the Company’s obligation to reimburse described in the preceding sentence shall cease on the date Executive becomes eligible for coverage under another group health plan offered by a new employer of Executive or covered under a group health plan of the employer of Executive’s spouse, in either case, which does not impose pre-existing condition limitations on Executive’s coverage. Nothing herein shall be construed to extend the period of time over which health care premium continuation coverage shall be provided to Executive or his dependents beyond that mandated by law.

If, during the Term, the Company terminates Executive’s service without Cause under Section 6(i) hereof or Executive terminates his service for Good Reason under Section 7 hereof, for purposes of determining the vested portions of Executive’s stock options and any other equity compensation awards then outstanding, Executive shall be deemed to have terminated service twelve (12) months following the date of Executive’s actual termination of service.

(iii) Termination by Executive Without Good Reason or by the Company for Cause. If, during the Term, Executive terminates his service under Section 7(i) hereof without Good Reason or the Company terminates Executive’s service under Section 6(ii) hereof for Cause, Executive shall be entitled to no further compensation or other benefits under this Agreement except for the Accrued Amounts, payable in a single lump sum as soon as practicable following the date of termination.

(iv) Death; Disability. If Executive’s service is terminated during the Term by reason of Executive’s death or for Disability, Executive or Executive’s estate, as the case may be, shall be entitled to the following payments:

(a) The Accrued Amounts, as soon as reasonably practicable following the date of termination;

(b) Any Bonus that has been actually earned as of or prior to the termination date, but has not been paid, payable at the time payment is made to other similarly-situated executives of the Company or its Affiliates, but in no event later than two and a half (2½) months after the close of the calendar year in which Executive becomes vested in such Bonus; and

(c) The amount payable, if any, as determined pursuant to Section 10(ii)(c), payable at the time payment is made to other similarly-situated executives of the Company or its Affiliates, but in no event later than two and a half (2½) months after the close of the calendar year in which Executive’s right to the Bonus is no longer subject to a substantial risk of forfeiture, Executive becomes vested in such Bonus.

If Executive’s service is terminated during the Term by reason of Executive’s death or for Disability, the treatment of any equity compensation awards held by Executive shall be governed by the terms of the plan or agreement under which such awards were granted.

(v) Termination on or After a Change in Control. If, within twenty-four (24) months following a Change in Control (as defined in the Equity Plan), the Company terminates Executive’s service without Cause under Section 6(i) hereof or Executive terminates his service for Good Reason under Section 7 hereof, Executive shall be entitled to the following payments, subject to Section 13:

(a) The Accrued Amounts, as soon as reasonably practicable following the date of termination;

(b) Any Bonus that has been actually earned as of or prior to the termination date, but has not been paid, payable at the time payment is made to other similarly-situated executives of the Company or its Affiliates, but in no event later than two and a half (2½) months after the close of the calendar year in which Executive’s right to the Bonus is no longer subject to a substantial risk of forfeiture;

(d) Continuing payments of Base Salary, payable in accordance with regular payroll practices of the Company, for twenty-four (24) months following the date of termination;

(e) Cash reimbursement of amounts paid by Executive (sufficient to cover full family health care premiums) for a period of twenty-four (24) months following the termination of Executive’s service if Executive elects continuation of coverage. The foregoing notwithstanding, the Company’s obligation to reimburse described in the preceding sentence shall cease on the date Executive becomes eligible for coverage under another group health plan offered by a new employer of Executive or covered under a group health plan of the employer of Executive’s spouse, in either case, which does not impose pre-existing condition limitations on Executive’s coverage. Nothing herein shall be construed to extend the period of time over which health care premium continuation coverage shall be provided to Executive or his dependents beyond that mandated by law;

(f) A lump sum cash amount equal to two (2) times Executive’s average annual Bonus over the three (3) completed years immediately preceding the date of the Change in Control, payable as soon as reasonably practicable after the date of termination; and

(g) All equity (including options, RSUs and other stock) awards outstanding as of the Change in Control and held by Executive on the date of termination shall immediately vest and become non-forfeitable.

(vi) Expiration. If the Term of this Agreement expires due to either the Company or Executive electing not to renew the Term in accordance with Section 2, and the Company does not offer Executive continued service in the same or a substantially similar position as, or in a higher position than, his position on the date of the expiration of the Term, and at a compensation level that is the same or substantially similar to that in effect on the date of the expiration of the Term, Executive shall be entitled to resign from service with the Company and receive the following payments:

(a) The Accrued Amounts, as soon as reasonably practicable following the date of termination;

(b) Any Bonus that has been actually earned as of or prior to the termination date, but has not been paid, payable at the time payment is made to other similarly-situated executives of the Corporation, but in no event later than two and a half (2½) months after the close of the calendar year in which Executive’s right to the Bonus is no longer subject to a substantial risk of forfeiture;

(c) The amount payable, if any, as determined pursuant to Section 10(ii)(c), payable at the time payment is made to other similarly-situated executives of the Corporation, but in no event later than two and a half (2½) months after the close of the calendar year in which Executive would have become vested in such Bonus;

(d) Continuing payments of Base Salary, payable in accordance with regular payroll practices of the Company, for twelve (12) months following the date of termination; and

(e) Cash reimbursement of amounts paid by Executive (sufficient to cover full family health care premiums) for a period of eighteen (18) months following the termination of Executive’s service if Executive elects continuation of coverage. The foregoing notwithstanding, the Company’s obligation to reimburse described in the preceding sentence shall cease on the date Executive becomes eligible for coverage under another group health plan offered by a new employer of Executive or covered under a group health plan of the employer of Executive’s spouse, in either case, which does not impose pre-existing condition limitations on Executive’s coverage. Nothing herein shall be construed to extend the period of time over which health care premium continuation coverage shall be provided to Executive or his dependents beyond that mandated by law. The foregoing notwithstanding, the Company’s obligation to such health care premiums described in the preceding sentence shall cease on the date Executive becomes eligible for coverage under another group health plan offered by a new employer of Executive or covered under a group health plan of the employer of Executive’s spouse, in either case, which does not impose pre-existing condition limitations on Executive’s coverage. Nothing herein shall be construed to extend

the period of time over which health care premium continuation coverage shall be provided to Executive or Executive’s dependents beyond that mandated by law.

Except as provided in Section 10(i), Executive shall not be entitled to payment of the amounts described in this subsection (vi) if the Company offers Executive continued service in the same or a substantially similar position as, or in a higher position than, his position on the date of expiration of the Term, and at a compensation level that is the same or a substantially similar to that in effect on the date of the expiration of the Term, and Executive declines the offer.

(vii) No Duplication of Benefits. Executive shall only be eligible for termination payments and benefits, if any, under one of the provisions of this Section 10. For example, if Executive receives payments and benefits under Section 10(ii) of this Agreement, Executive shall not be eligible to receive payments or benefits under Sections 10(iv), 10(v), or 10(vi). Any termination payments made and benefits provided to Executive under this Agreement shall be in lieu of any other severance payments or benefits for which Executive may be eligible under the IPG Photonics Corporation Executive Severance Plan, as amended, or any similar or successor plan or under the Worker Adjustment Retraining Notification Act of 1988 or any similar state statute or regulation.

(viii) No Mitigation or Offset. In the event of any termination of Executive’s service under this Section 10, Executive shall be under no obligation to seek other employment or assignments or otherwise mitigate his damages, and there shall be no offset against amounts due to Executive under this Agreement on account of any remuneration or benefit attributable to any subsequent employment or assignment obtained by Executive, except as provided in Sections 10(ii)(e), 10(v)(e) and 10(vi)(e).

(viii) Compensation Recovery Policy. Notwithstanding any provision in this Agreement to the contrary, payments under this Agreement will be subject to any Compensation Recovery Policy established by the Company and amended from time to time.

11. Nature of Payments. Upon termination of service pursuant to Sections 6, 7, 8 or 9, Executive will be released from any duties and obligations to the Company set forth in this Agreement (except the duties and obligations under the Restrictive Covenant Agreement and as set forth in Section 12 hereof and the obligation under Sections 13 and 23) and the obligations of the Company to Executive under this Agreement will be as set forth in Section 10.

12. Restrictive Covenant Agreement. Executive has executed and delivered a Confidentiality, Non-Competition and Confirmatory Assignment Agreement prior to or contemporaneous with the date of this Agreement (together with any similar or successor agreements, referred to herein as the “Restrictive Covenant Agreement”), and Executive agrees that, as part of this Agreement, Executive shall comply with the terms of the Restrictive Covenant Agreement. Notwithstanding Section 10(iii) of this Agreement, if (a) Executive terminates service other than for Good Reason and, thus, is not entitled to the payments and benefits under Section 10(ii) of this Agreement, and (b) (i) Executive receives a written offer of

employment during the Non-Competition Period set forth in Section 2(a) of the Restrictive Covenant, or (ii) Executive is not able to find suitable employment in his field in relation to his skills, position and base salary, which employment would not contravene Section 2(a) of the Restrictive Covenant, after a good faith effort by Executive to search for such employment, and (iii) the Company notifies Executive that it intends to enforce the non-compete provisions of such Section 2(a) against Executive, then the Company shall pay to Executive an amount equal to the semi-monthly amount of Executive’s Base Salary for each semi-monthly payroll period beginning (A) on the effective date of the written offer of employment referred to above or (B) during the period in which Executive is not able to find suitable employment, and ending on the earliest to occur of (I) the end of the Non-Competition Period set forth in such Section 2(a), or (II) the date as of which Executive begins new employment with an employer, which employment would not contravene Section 2(a) of the Restrictive Covenant. For the avoidance of doubt, the non-competition and other provisions of the Restrictive Covenant Agreement in all events shall continue to apply until the end of the Non-Competition Period set forth in Section 2(a) of the Restrictive Covenant, regardless of Executive’s new employment with an employer that would not contravene Section 2(a) of the Restrictive Covenant, the subsequent termination of such employment or any other event.

13. Release. Any and all amounts payable and benefits or additional rights provided pursuant to this Agreement beyond Accrued Amounts shall only be payable if Executive delivers to the Company an original, signed release of claims of Executive occurring up to the release date, in a form substantially the same as attached hereto as Exhibit A (the “Release”). The Company shall deliver the Release to Executive within ten (10) calendar days of the date Executive’s service terminates and Executive must deliver to the Company and not revoke an executed and enforceable Release no later than sixty (60) calendar days after the date Executive’s service terminates (the “Release Deadline”). Payment of the amounts described in Section 10 shall commence no earlier than the date on which Executive delivers to the Corporation and does not revoke an executed and enforceable release as described herein. As part of the Release, Executive shall affirm that Executive (i) has advised the Company in writing, of any facts that Executive is aware of that constitute or might constitute a violation of any ethical, legal or contractual standards or obligations of the Company or any Affiliate, and (ii) is not aware of any existing or threatened claims, charges, or lawsuits that Executive has not disclosed to the Company.

14. Indemnification. IPG Photonics Corporation shall maintain a directors’ and officers’ liability insurance policy covering Executive on the same basis as in effect for other senior executive employees, and shall provide indemnity to Executive by a separate, written indemnification agreement.

15. Notices. Any and all notices, requests, demands, and other communications provided for herein shall be sufficient if in writing and shall be deemed to have been duly given if delivered by hand or if sent by registered or certified mail, return receipt requested, sent by a nationally recognized overnight courier for delivery, or sent by other electronic means generating a receipt confirming delivery of the notice. Notice shall be deemed to have been given when notice is received by the party on whom the notice was served. Notice to the Company shall be addressed to the Company at its principal office, with attention to the General Counsel, and

notice to Executive shall be addressed to Executive at Executive’s last address as shown on the records of the Company.

16. Governing Law. This Agreement shall be governed by, construed and enforced in accordance with the substantive laws of the Commonwealth of Massachusetts except that the social security insurance and mandatory statutory provisions set forth under company law shall be governed by the laws of the Federal Republic of Germany, without regard to its internal conflicts of law provisions.

17. Severability. In the event that any provision of this Agreement shall be determined to be invalid, illegal or otherwise unenforceable or contrary to law or public policy, the enforceability of the other provisions in this Agreement shall not be affected thereby.

18. Assignment; Successors. Executive recognizes that this is an agreement for personal services and that Executive may not assign this Agreement. The Agreement shall inure to the benefit of and be binding upon the Company’s successors and assigns.

19. Entire Agreement/Amendment. This Agreement and the Confidentiality, Non-Competition and Confirmatory Assignment Agreement referred to in Section 12 constitute the entire agreement between the Parties with respect to the subject matter hereof and supersedes any and all other agreements, either oral or in writing (including the Prior Agreement), among the Parties hereto with respect to the subject matter hereof. This Agreement may not be amended except by written agreement signed by both Parties. Executive hereby acknowledges and agrees that, during the Term, Executive shall have no rights or benefits under the IPG Photonics Corporation Executive Severance Plan, as amended, or any similar or successor plan.

20. Execution in Counterparts. This Agreement may be executed in one or more counterparts, and by the different Parties in separate counterparts, each of which shall be deemed to be an original but all of which taken together shall constitute one and the same agreement (and all signatures need not appear on any one counterpart), and this Agreement shall become effective when one or more counterparts has been signed by each of the Parties hereto and delivered to each of the other Parties hereto. A copy of this Agreement that is executed by a Party and transmitted by that Party to the other Party by facsimile or as an attachment (e.g., in “.tif” or “.pdf” format) to an email shall be binding upon the signatory to the same extent as a copy hereof containing that Party’s original signature.

21. Waiver. The failure of either of the Parties to at any time enforce any of the provisions of this Agreement shall not be deemed or construed to be a waiver of any such provision, nor to in any way affect the validity of this Agreement or any provision hereof or the right of either of the Parties to enforce each and every provision of this Agreement. No waiver of any breach of any of the provisions of this Agreement shall be effective unless set forth in a written instrument executed by the party against whom or which enforcement of such waiver is sought, and no waiver of any such breach shall be construed or deemed to be a waiver of any other or subsequent breach.

22. Capacity. Executive and the Company hereby represent and warrant to the other that: (i) Executive or the Company has full power, authority and capacity to execute and deliver

this Agreement, and to perform Executive’s or the Company’s obligations hereunder; (ii) such execution, delivery and performance will not (and with the giving of notice or lapse of time or both would not) result in the breach of any agreements or other obligations to which Executive or the Company is a party or Executive or the Company is otherwise bound; and (iii) this Agreement is Executive’s or the Company’s valid and binding obligation in accordance with its terms.

23. Arbitration. Any controversy or claim arising out of or relating to this Agreement or the breach thereof or otherwise arising out of Executive's service or the termination of that service (including, without limitation, any claims of unlawful service discrimination whether based on age or otherwise) shall, to the fullest extent permitted by law, be settled by a single arbitrator in any forum and form agreed upon by the parties or, in the absence of such an agreement, under the auspices of the International Arbitration Association ("IAA") in Frankfurt/Main, Germany in accordance with the rules of the IAA governing dispute resolution of personal services, including, but not limited to, the rules and procedures applicable to the selection of arbitrators.
