Transition Agreement and Release, dated February 4, 2019, between the Company and Paul Sechrist

THIS TRANSITION AGREEMENT AND RELEASE (the “Agreement”) is entered into as of February 4, 2019 (“Execution Date”) by Paul Sechrist (“Executive”) and Coherent, Inc. for and on behalf of itself and its predecessors, successors, assigns, parents, subsidiaries, branches, affiliated entities and related entities (collectively, “Company”). Executive and Company are collectively referred to in this Agreement as the “Parties.”

WHEREAS, Executive has been employed by the Company, and Executive’s employment relationship with the Company will be terminated and Executive will retire as of September 30, 2021 (the “Separation Date”);

WHEREAS, Executive effective on September 29, 2019 (“Transition Date”) will transition to the role of Special Advisor to the Chief Executive Officer;

WHEREAS, the Company wishes to set forth the terms of Executive’s role as Special Advisor to the Chief Executive Officer in exchange for the agreements expressed herein;

WHEREAS, this Agreement sets forth the terms and conditions of Executive’s role as Special Advisor to the Chief Executive Officer and any continuing obligations of the parties to one another following the end of the employment relationship;

WHEREAS, each of the undersigned parties to this Agreement has had ample opportunity to review the facts and law relevant to this issue, has consulted fully and freely with competent counsel of its choice if desired, and has entered this Agreement knowingly and intelligently without duress or coercion from any source and Executive has had a reasonable time in which to consider whether to sign this Agreement.

NOW, THEREFORE, in consideration of the foregoing recitals and the mutual promises contained below, it is agreed as follows:

1.Cooperation and Provision of Services. From the Transition Date through the Separation Date, Executive shall perform such strategic and other services reasonably requested by the Chief Executive Officer, with such services not to exceed twenty-five hours per month. Executive agrees to fully cooperate with the orderly transfer of his responsibilities as the Company may direct, including, without limitation, after the Separation Date: (i) assisting in the transition of his duties to those who will assume his duties; (ii) complying with any reasonable Company request for information after the Separation Date; (iii) making himself reasonably available in connection with any and all claims, disputes, negotiations, investigations, and lawsuits or administrative proceedings involving the Company or its affiliates; and (iv) providing thorough and accurate information or documents, providing truthful declarations or statements to the Company or its affiliates, meeting with attorneys or other representatives of the Company or its affiliates, preparing for and giving thorough and truthful testimony, and/or otherwise cooperating in the investigation, defense or prosecution of proceedings involving the Company.

2.    Payments by the Company. In consideration for (i) the Executive’s execution, without revocation, and compliance with this Agreement, including the release of claims below, (ii) Executive’s execution of the Release no earlier than the day following the Transition Date, (iii) Executive not revoking the Release prior to the eighth day following such execution and (iv) Executive providing the services set forth in paragraph 1 and provided that the Company does not terminate Executive’s employment for Cause, the Company will provide Executive with a base salary at a rate no less than that base salary in effect on the Execution Date for the period from the Transition Date through the Separation Date and Executive shall continue to vest in Executive’s outstanding equity awards under the Company’s 2011 Equity Incentive Plan according to their terms during the period from the Transition Date through the Separation Date (such base salary and continued vesting, collectively, “Benefits”). Executive acknowledges and understands that such Benefits will be reduced by any and all applicable federal, state, or local payroll tax withholding or other authorized deductions permitted by applicable law. Executive also acknowledges and understands that this Agreement provides no other rights to compensation or benefits for the period from the Transition Date through the Separation Date. Executive acknowledges that the Benefits provided to Executive as set forth above are greater than the sum to which Executive is otherwise entitled to receive without executing this Agreement, and Executive agrees that these Benefits are in excess of those to which Executive is otherwise entitled without a release of claims under the Company’s policies and procedures, or under any law, agreement or plan, written, oral or implied.

3.    Employment Separation Date and Certain Requirements. Executive’s employment relationship with the Company will be terminated as of the Separation Date, unless earlier terminated by the Company for Cause (as hereafter defined). The period of Executive’s employment relationship with the Company is herein referred to as the “Term”. Executive understands and agrees that the terms contained in this Agreement are offered by the Company contingent upon Executive’s fulfillment of his obligations under this Agreement including, without limitation, serving as a special advisor to the Chief Executive Officer and cooperation in an orderly transition of Executive’s duties and execution and nonrevocation of the release contained within this Agreement and the execution and nonrevocation of the General Release of Claims attached hereto as Exhibit A (“Release”). For purposes of this Agreement, “Cause” means (i)(A) non-performance of Executive’s duties as defined in Section (1) or breach of the provisions of this Agreement; (B) misconduct or gross negligence in the performance of Executive’s duties; (C) Executive’s refusal or failure to adhere to any policy of the Company or any of its affiliates or follow any lawful directive of the Chief Executive Officer; or (D) Executive’s engagement in conduct that discriminates or harasses another employee or contractor of the Company or any of its affiliates on the basis of gender, race, color, creed, religion, sexual orientation, marital status, veteran status, or any other category protected by applicable law; (ii) Executive’s breach of a fiduciary duty owed to the Company or any of its affiliates; (iii)(A) Executive’s commission of a felony; (B) Executive’s misappropriation (or attempted misappropriation) of any of the funds, information, or property of the Company or any of its affiliates; or (C) Executive’s commission of any other act or omission involving theft, moral turpitude, misappropriation, embezzlement, fraud or dishonesty; or (iv) other misconduct or negligence by Executive that has caused or is likely to cause an adverse impact, monetary, reputational or otherwise, to the Company or any of its affiliates or on Executive’s ability

to effectively perform Executive’s duties with the Company or any affiliate, as determined in good faith by the Board of Directors of the Company.

4.    Valid Consideration. Executive and Company agree that the Benefits described in paragraph 2 are in excess of those required by the Company’s policies or procedures or by any pre-existing contractual obligation of the Company or by any statute, regulation or ordinance, and such excess amounts are offered by the Company solely as consideration for this Agreement. In the event Executive fails to abide by the terms of this Agreement, the Company may elect, at its option and without waiver of other rights or remedies it may have, not to pay or provide any excess Benefits, and if in breach of Section (5) to seek to recover previously paid excess Benefits.

5.    Noncompetition and Reaffirmation of Restrictive Agreements. Executive acknowledges the goodwill the Company has built up in conjunction with its business operations, at significant time and expense to the Company. Employee therefore agrees that, during the Term, unless agreed to in writing by the Chief Executive Officer of the Company, Employee will not, directly or indirectly, whether through his own business, or as an employee, salesman, consultant, independent contractor, officer or director, or otherwise, for any person or entity, aid or assist in any manner, any person or entity that engages in a business which is which is competitive with the current or reasonably anticipated business of the Company, including, without limitation, the laser industry or the photonics industry; provided, however, Employee may own, directly or indirectly, solely as an investment, securities of any company which is registered on any national securities exchange or actively traded in a generally recognized over the counter market so long as Employee owns less than two percent (2%) of the outstanding securities of such company. Executive expressly reaffirms and incorporates as part of this Agreement the Employee Agreement dated June 22, 1998 (“Employee Agreement”).

6.    Waiver and Release. To the extent permitted by applicable law, in exchange for the consideration provided in this Agreement, Executive, for himself and his heirs, executors, representatives, agents, insurers, administrators, successors and assigns (collectively, “Releasors”) irrevocably and unconditionally fully and forever waives, releases and discharges the Company and each and all of its present and former officers, agents, directors, managers, employees, representatives, affiliates, shareholders, attorneys, members, and each of their successors and assigns, and all persons acting by, through, under or in concert with, and individually in their official capacities (collectively, “Releasees”) from any and all claims, demands, actions, causes of action, obligations, judgments, rights, fees, damages, liabilities and expenses (inclusive of attorneys’ fees) of any kind whatsoever, whether known or unknown (collectively, “Claim” or “Claims”), including, without limitation, any Claims under any federal, state, local or foreign law, that Releasors may have, have ever had or may in the future have arising out of, or in any way related to Executive’s hire, benefits, employment, termination or separation from employment and any actual or alleged act, omission, transaction, practice, conduct, occurrence or other matter that existed or arose on or before the date of his execution of this Agreement, including, but not limited to any claims, under (as amended) the United States Constitution, Title VII of the Civil Rights Act, the Age Discrimination in Employment Act, the Americans with Disabilities Act, the Equal Pay Act, the Employee Retirement Income Security Act (with respect to unvested benefits), the Civil Rights Act of 1991, 42 U.S.C. section 1981, the Sarbanes-Oxley Act of 2002, the Worker Adjustment and Retraining

Notification Act, the Family Medical Leave Act, the Rehabilitation Act, the Occupational Safety and Health Act, the Fair Labor Standards Act, the California Fair Employment and Housing Act, the California Family Rights Act, the California Business and Professions Codes, Civil Code, Labor Code, and Government Code, and/or any other federal, state or local law (statutory, regulatory or otherwise) that may be legally waived and released and any common law tort and/or contract claims, including, but not limited to, any claims of wrongful discharge, defamation, emotional distress, tortious interference with contract, invasion of privacy, nonphysical injury, personal injury or sickness or any other harm.

Nothing in this Agreement will be construed to (i) limit or affect Executive’s right to challenge the validity of this release; (ii) in any way interfere with Executive’s right and responsibility to give truthful testimony under oath; or (iii) prohibit Executive from participating in an investigation, filing a charge or otherwise communicating with any federal, state or local government office, official or agency, including, but not limited to, the Equal Employment Opportunity Commission, Department of Labor, National Labor Relations Board, or the Securities and Exchange Commission. However, Executive expressly promises never to seek or accept any compensatory damages, back pay, front pay, or reinstatement remedies with respect any Claim that Executive has released in this Agreement. Furthermore, this waiver and release of claims excludes, and Executive does not waive, release or discharge, any claims under state workers’ compensation or unemployment laws Executive has against the Company and/or any claims by Executive that cannot be released by a private settlement agreement. In addition, nothing in this Agreement is intended to affect or to waive any of Executive's vested rights under the Coherent, Inc. 401(k) Retirement Plan or the Coherent, Inc. Deferred Compensation Plan.

7.    Unknown Claims. Executive agrees that his waiver and release of claims extends to all Claims of every nature and kind, known or unknown, suspected or unsuspected, past or present, arising from or attributable to Executive’s employment or separation of employment with the Company. Executive therefore waives the protection of California Civil Code section 1542 or any analogous state law or federal law or regulation. Section 1542 reads as follows:

8.    Resignation from All Positions. Effective as of 5:00 p.m. on September 27, 2019 (California time), Executive hereby resigns from any and all positions he holds with the Company except for the position of Special Advisor to the Chief Executive Officer of the Company, and will not thereafter represent himself as being an executive officer of the Company for any purpose. After the Separation Date, Executive will not represent himself as being an executive officer, officer, attorney, agent or representative of the Company for any purpose.

9.    Confidential Information and Non-Solicitation.

information, documents, materials and other information, in tangible and intangible form about the Company, its business, its customers and its methods of operation (collectively, “Confidential Information”), including but not limited to all trade secrets, confidential knowledge, data or other proprietary information relating to products, processes, know-how, designs, formulas, developmental or experimental work, computer programs, technology, products, product specifications, techniques, inventions, discoveries, improvements, research, test results, databases, other original works of authorship, customer lists or other information related to customers or prospective customers, marketing, sales and business plans, strategies, forecasts, budgets, projections, other financial information, cardholder information, or other information pertaining to any business of the Company or any of its employees, customers, clients, members, joint ventures, vendors, licensees, consultants or third parties with whom it does business. Executive understands that the above list is not exhaustive, and that Confidential Information also includes other information that is marked or otherwise identified as confidential or proprietary, or that would otherwise appear to a reasonable person to be confidential or proprietary in the context and circumstances in which the information is known or used.

Executive will treat all Confidential Information as strictly confidential and will not disclose or use any Confidential Information that Executive acquired, developed or created by reason of Executive’s employment, except (i) if compelled by a valid subpoena or as otherwise required by law, but, in any such case, and to the extent permitted by law, only after providing the Company with prior written notice as soon as practicable and with reasonable opportunity to contest such subpoena or other requirement for information, (ii) for information that is or becomes publicly available other than through Executive’s breach of any of Executive’s obligations to the Company, (iii) pursuant to paragraph 13 below, or (iv) pursuant to 18 U.S.C. section 1833(b) described below.

secret, except pursuant to court order. Executive understands that in the event it is determined that disclosure of Company trade secrets was not done in good faith as described in this paragraph 5.B, Executive may be subject to substantial damages, including punitive damages and attorneys’ fees.

10.    Inventions. In exchange for receiving the benefits set forth in this Agreement, Executive hereby assigns to the Company, or its designee, all of Executive’s right, title and interest throughout the world in and to any and all inventions, original works of authorship, designs, trademarks, formulae, processes, domain names, databases (and their contents), developments, concepts, know-how, improvements of trade secrets, whether or not patentable or registrable under patent, copyright, trademark or similar laws, (“Inventions”) which Executive solely or jointly conceived or developed or reduced to practice, or caused to be conceived or developed or reduced to practice, during Executive’s employment with the Company. Executive acknowledges and agrees

that Executive does not have any Inventions which were made by Executive prior to the commencement of Executive’s employment with the Company. Upon request by the Company, Executive agrees to execute any and all applications, assignments or other instruments that the Company deems necessary to evidence the foregoing assignment or to apply for and obtain patents or trademark or copyright registrations in the United States or any foreign country or otherwise to protect the Company’s interest in this Agreement (without additional compensation to Executive). Furthermore, Executive hereby appoints each of the Company’s managers, acting severally, as Executive’s attorney-in-fact to execute such documents on Executive’s behalf. Executive understands that the provisions of this assignment of inventions to the Company are limited by Section 2870 of the California Labor Code, which states the following: 2870.   (a) Any provision in an employment agreement which provides that an employee shall assign, or offer to assign, any of his or her rights in an invention to his or her employer shall not apply to an invention that the employee developed entirely on his or her own time without using the employer’s equipment, supplies, facilities, or trade secret information except for those inventions that either: (1) Relate at the time of conception or reduction to practice of the invention to the employer’s business, or actual or demonstrably anticipated research or development of the employer; or (2) Result from any work performed by the employee for the employer. (b) To the extent a provision in an employment agreement purports to require an employee to assign an invention otherwise excluded from being required to be assigned under subdivision (a), the provision is against the public policy of this state and is unenforceable.

11.    Return of Property. Upon the Separation Date, Executive will return to the Company all files, memoranda, records, credit cards, pagers, computers, computer files, passwords and pass keys, card keys, or related physical or electronic access devices, and any and all other property received from the Company or any of its current or former executives or generated by Executive in the course of employment. Upon the Separation Date, Executive will delete all electronic data and files pertaining to Executive’s job or the Company’s business operations, existing on Executive’s personal computers, other personal electronic devices, and on any email account maintained or accessible by Executive. Without limitation on the foregoing, Executive will upon the Separation Date return to the Company all of the Company’s property, including records, vendor/client lists, other lists, data, notes, reports, proposals, correspondence, specifications, drawings, blueprints, sketches, laboratory notebooks, flow charts, materials, equipment, other documents or property or other non-public information, or copies or reproductions of any of the aforementioned items, electronic devices (including, but not limited to, any laptop computer, blackberry or similar device, or cellphone), or other documents or property which, in each case, Executive obtained, received or produced in connection with his employment with the Company or that was within Executive’s possession and control.

12.    Non-Disparagement. Subject to paragraph 5.A. above and paragraph 13 below, and except to the extent Executive provides testimony under oath, Executive will not make any statements, whether orally or in writing, about the Company or any of its present or former officers, agents, directors, managers, employees, representatives, affiliates, shareholders, members, or any of their successors or assigns, or to engage in conduct which could reasonably be expected to adversely affect the reputation or business of the Company and/or any of its present or former

officers, agents, directors, managers, employees, representatives, affiliates, shareholders, members, and each of their successors and assigns.

13.    Permitted Communications. Executive acknowledges that nothing in this Agreement prohibits or restricts Executive from initiating communications directly with, responding to any inquiry from, or providing information to or testimony before, the Securities and Exchange Commission, Department of Justice, or any other governmental agency or self-regulatory organization, about actual or potential violations of laws or regulations. Executive further acknowledges that Executive is not required to obtain the Company’s prior authorization before engaging in such communications, nor is Executive required to inform the Company about such communications.

14.    No Admission. The Parties agree and acknowledge that this Agreement, and compliance with this Agreement, will not be construed as an admission by the Company of any liability whatsoever, or as an admission by the Company of any violation of the rights of Executive or any person, or violation of any order, law, statute, duty, or contract whatsoever against Executive or any person.

15.    Assignment. This Agreement will be binding upon the Parties and upon their heirs, administrators, representatives, executors, successors, and assigns, and will inure to the benefit of said parties and each of them and to their heirs, administrators, representatives, executors, successors, and assigns. Executive expressly warrants that he has not transferred to any person or entity any rights, causes of action or claims released in this Agreement. Any purported assignment by Executive will be null and void.

16.    Severability. Should any provision of this Agreement be held by a court of competent jurisdiction to be enforceable only if modified, or if any portion of this Agreement will be held as unenforceable and thus stricken, such holding will not affect the validity of the remainder of this Agreement, the balance of which will continue to be binding upon the Parties with any such modification to become a part of, and treated as though originally set forth in, this Agreement. The Parties further agree that any such court is expressly authorized to modify any such unenforceable provision of this Agreement in lieu of severing such unenforceable provision from this Agreement in its entirety, whether by rewriting the offending provision, deleting any or all of the offending provision, adding additional language to this Agreement or by making such other modifications as it deems warranted to carry out the intent and agreement of the Parties as embodied in this Agreement to the maximum extent permitted by law. However, if a court should hold that Executive’s waiver and release of claims is void or voidable, in whole or in part, the Company at its election may recover the excess Benefits paid or provided under this Agreement.

17.    Entire Agreement. This Agreement, including the Release, sets forth the entire agreement between the Parties and fully supersedes any and all prior agreements or understandings, written or oral, between the Parties pertaining to the subject matter of this Agreement (except that Executive will continue to be bound by the confidentiality, intellectual property and non-solicitation provisions of the Employee Agreement and/or any similar agreement previously executed by Executive will remain fully enforceable and binding on the Parties, all subject to paragraphs 5.A.

and 13 of this Agreement). Executive acknowledges and confirms that his participation in the Company’s Change of Control Severance Plan will cease as of September 28, 2019. Executive represents and acknowledges that in executing this Agreement Executive did not rely and has not relied upon any representation or statement made by the Company or by any of the Company’s agents, attorneys, or representatives with regard to the subject matter, basis or effect of this Agreement or otherwise, other than those specifically stated in this written Agreement. This Agreement may be modified only in a written document signed by the Parties and referring specifically to this Agreement.

18.    Governing Law. This Agreement will be interpreted in accordance with the plain meaning of its terms and not strictly for or against any of the Parties. Except to the extent that federal law applies, this Agreement is entered into under California law and will be construed and governed under the laws of the State of California

19.    Arbitration and Equitable Relief.

CONSTITUTES A WAIVER OF EXECUTIVE’S RIGHT TO A JURY TRIAL AND RELATES TO THE RESOLUTION OF ALL DISPUTES RELATING TO ALL ASPECTS OF THE RELATIONSHIP BETWEEN THE PARTIES.

20.    Taxes. The Company and affiliates make no representations with regard to the effect on Executive’s federal, state, or local income tax liability with regard to the Benefits and any other payments or benefits being provided to Executive. Executive hereby assumes full and sole responsibility for payment of taxes due, if any, on the consideration tendered herein and further agrees to defend, indemnify, and hold the Company and its affiliates harmless from and against any loss, liability, obligation, action, cause of action, claims, demands, or other expenses of any nature whatsoever, relating to, in connection with, or arising out of the payment of said taxes and interest, and/or penalties imposed, arising out of any such tax.

21.    Section 409A. The Company and Executive intend that this Agreement and the payments provided hereunder be exempt from the requirements of Section 409A of the Internal Revenue Code of 1986, as amended (“Section 409A”) to the maximum extent possible, or to the extent Section 409A is applicable to this Agreement, the Company and Executive intend that this Agreement and any payments thereunder comply with the deferral, payout and other limitations and restrictions imposed under Section 409A. Notwithstanding anything herein to the contrary, this Agreement is intended to be interpreted, operated and administered in a manner consistent with such intentions; provided, however that in no event shall the Company or any of its affiliates (or any of their successors) be liable for any additional tax, interest or penalty that may be imposed on the Executive pursuant to Section 409A or for any damages incurred by the Executive as a result of this Agreement (or the payments hereunder) failing to comply with, or be exempt from Section 409A. Without limiting the generality of the foregoing, and notwithstanding any other provision of this Agreement to the contrary if at the time the Executive’s employment hereunder terminates, the Executive is a “specified employee” within the meaning of Section 409A, then to the extent necessary to avoid subjecting the Executive to the imposition of any additional tax or interest under Section 409A, amounts that would (but for this provision) be payable within six months following the date of the Executive’s separation from service shall not be paid to the Executive during such period, but shall instead be paid in a lump sum on the first payroll date that occurs on or after the date six months and one day following the date of such Executive’s separation from service or, if earlier, upon the Executive’s death.

22.    Knowing and Voluntary Acknowledgement. Executive agrees and acknowledges that: (a) Executive has read the terms of this Agreement and understands all of its terms; (b) Executive is hereby advised of Executive’s right to consult with an attorney of his choice prior to executing this Agreement; (c) this Agreement represents an important legal and binding agreement, that he is executing this Agreement voluntarily, free from duress, undue pressure or influence, harassment or intimidation and that he enters into it with full knowledge of its intent and terms; and (d) he is not waiving or releasing rights or claims that may arise after his execution of this Agreement.

Executive understands and agrees that Executive has been given at least 21 days (the “Consideration Period”) within which to consider this Agreement and its ramifications and discuss the terms of this

Agreement with the Company before executing it. Executive further acknowledges that any modification of this Agreement, whether material or immaterial, will not restart or change the Consideration Period.

Executive further understands and agrees that once Executive signs this Agreement, he will have an additional 7 days in which to revoke his acceptance of this Agreement. To do so, Executive must provide notice of revocation prior to the expiration of the 7-day revocation period to Mark Rakic, Senior Vice President of Human Resources in writing via hand delivery, fax at ###-###-#### or by e-mail to ***@***, if using email, with a copy to ***@***, or to their designated successors. Provided Executive has not revoked his acceptance of this Agreement during such 7-day revocation period, this Agreement shall become effective the eighth day after the Executive signs this Agreement (“Effective Date”).

Executive acknowledges that, even if this Agreement is not executed or is canceled or revoked by Executive, the provisions of the Employee Agreement, that otherwise by their terms survive termination of Executive’s employment shall remain in full force and effect.

23.    Counterparts. This Agreement may be signed in counterparts, each of which will be deemed an original, but all of which, taken together, will constitute the same instrument; provided, however, that this Agreement will be of no force or effect unless executed by both parties.

24.    Captions. Captions and headings of the sections and paragraphs of this Agreement are intended solely for convenience and no provision of this Agreement is to be construed by reference to the caption or heading of any section or paragraph.

IN WITNESS WHEREOF, the parties have executed this Agreement as of the dates indicated below.

This General Release of Claims (“Release”) is entered into on the date set forth below by Paul Sechrist (“Executive”) and Coherent, Inc. for and on behalf of itself and its predecessors, successors, assigns, parents, subsidiaries, branches, affiliated entities and related entities (collectively, “Company”). In consideration for the Benefits set forth in the Transition Agreement and Release dated ___________________ (“Agreement”) and as a condition to Executive’s right to receive the Benefits (as described and set forth in the Agreement), Executive hereby agrees as follows:

1.    Waiver and Release. To the extent permitted by applicable law, in exchange for the consideration provided in the Agreement, Executive, for himself and his heirs, executors, representatives, agents, insurers, administrators, successors and assigns (collectively, “Releasors”) irrevocably and unconditionally fully and forever waives, releases and discharges the Company and each and all of its present and former officers, agents, directors, managers, employees, representatives, affiliates, shareholders, attorneys, members, and each of their successors and assigns, and all persons acting by, through, under or in concert with, and individually in their official capacities (collectively, “Releasees”) from any and all claims, demands, actions, causes of action, obligations, judgments, rights, fees, damages, liabilities and expenses (inclusive of attorneys’ fees) of any kind whatsoever, whether known or unknown (collectively, “Claim” or “Claims”), including, without limitation, any Claims under any federal, state, local or foreign law, that Releasors may have, have ever had or may in the future have arising out of, or in any way related to Executive’s hire, benefits, employment, termination or separation from employment and any actual or alleged act, omission, transaction, practice, conduct, occurrence or other matter that existed or arose on or before the date of his execution of this Release, including, but not limited to any claims, under (as amended) the United States Constitution, Title VII of the Civil Rights Act, the Age Discrimination in Employment Act, the Americans with Disabilities Act, the Equal Pay Act, the Employee Retirement Income Security Act (with respect to unvested benefits), the Civil Rights Act of 1991, 42 U.S.C. section 1981, the Sarbanes-Oxley Act of 2002, the Worker Adjustment and Retraining Notification Act, the Family Medical Leave Act, the Rehabilitation Act, the Occupational Safety and Health Act, the Fair Labor Standards Act, the California Fair Employment and Housing Act, the California Family Rights Act, the California Business and Professions Codes, Civil Code, Labor Code, and Government Code, and/or any other federal, state or local law (statutory, regulatory or otherwise) that may be legally waived and released and any common law tort and/or contract claims, including, but not limited to, any claims of wrongful discharge, defamation, emotional distress, tortious interference with contract, invasion of privacy, nonphysical injury, personal injury or sickness or any other harm.

Nothing in this Release or the Agreement will be construed to (i) limit or affect Executive’s right to challenge the validity of this release; (ii) in any way interfere with Executive’s right and responsibility to give truthful testimony under oath; or (iii) prohibit Executive from participating in an investigation, filing a charge or otherwise communicating with any federal, state or local government office, official or agency, including, but not limited to, the Equal Employment Opportunity Commission, Department of Labor, National Labor Relations Board, or the Securities

and Exchange Commission. However, Executive expressly promises never to seek or accept any compensatory damages, back pay, front pay, or reinstatement remedies with respect any Claim that Executive has released in this Release or the Agreement. Furthermore, this waiver and release of claims excludes, and Executive does not waive, release or discharge, any claims under state workers’ compensation or unemployment laws Executive has against the Company and/or any claims by Executive that cannot be released by a private settlement agreement. In addition, nothing in this Release is intended to affect or to waive any of Executive's vested rights under the Coherent, Inc. 401(k) Retirement Plan or the Coherent, Inc. Deferred Compensation Plan.

Executive affirms that he has been paid and/or has received all compensation, wages, bonuses and/or benefits to which he may be entitled and no other compensation, wages, bonuses and/or benefits are due to Executive except as provided in the Agreement. Executive represents that he has reported all injuries and illnesses arising out of Executive’s employment with the Company; has been properly provided any leave of absence required by applicable law because of his or a family members’ health condition or any other qualifying leave; and has not been subject to any improper treatment, conduct, or actions due to a request for or taking such leave.

2.    Unknown Claims. Executive agrees that his waiver and release of claims extends to all Claims of every nature and kind, known or unknown, suspected or unsuspected, past or present, arising from or attributable to Executive’s employment or separation of employment with the Company. Executive therefore waives the protection of California Civil Code section 1542 or any analogous state law or federal law or regulation. Section 1542 reads as follows:

3.    Knowing and Voluntary Acknowledgement. Executive agrees and acknowledges that: (a) Executive has read the terms of this Release and understands all of its terms; (b) Executive is hereby advised of Executive’s right to consult with an attorney of his choice prior to executing this Release; (c) this Release represents an important legal and binding agreement, that he is executing this Release voluntarily, free from duress, undue pressure or influence, harassment or intimidation and that he enters into it with full knowledge of its intent and terms; and (d) he is not waiving or releasing rights or claims that may arise after his execution of this Release.

Executive understands and agrees that Executive has been given at least 21 days (the “Release Consideration Period”) within which to consider this Release and its ramifications and discuss the terms of this Release with the Company before executing it. Executive further acknowledges that any modification of this Release, whether material or immaterial, will not restart or change the Release Consideration Period.

Executive further understands and agrees that once Executive signs this Release, he will have an additional 7 days in which to revoke this Release. To do so, Executive must provide notice of revocation prior to the expiration of the 7-day revocation period to Mark Rakic, Senior Vice President of Human Resources in writing via hand delivery, fax at ###-###-#### or by e-mail to

***@***, if using email, with a copy to ***@***, or their designated successors. Provided Executive has not revoked this Release during such 7-day revocation period, this Release shall become effective the eighth day after the Executive signs this Release (“Release Effective Date”).

IN WITNESS WHEREOF, Executive has executed this Release as of the date indicated below.
