sentence of this Section may vary the terms of a Participant’s participation on a case-by-case basis, as set forth in the Participant’s Participation
Agreement. A designated Eligible Executive shall not become a Participant unless and until the Participation Agreement is duly executed. Once participation in the Plan has commenced, a Participant shall remain a Participant until the first to occur
of (i) the Participant’s Nonqualifying Termination, (ii) the completion of the delivery of all benefits under the Plan following a Qualifying Termination under circumstances giving rise to a right to such benefits, or

or otherwise, and no such payment or benefit shall be offset or reduced by the amount of any compensation or benefits provided to the Participant in any subsequent employment. 

(b) The Company does not intend to duplicate severance benefits. Accordingly, the severance payments and benefits under the Plan to a
Participant shall be reduced by any severance benefits to which the Participant would otherwise be entitled under the Participant’s offer letter or employment agreement with the Company (if applicable), or any general severance policy or plan
maintained by the Company that provides for severance benefits (unless the agreement, policy or plan expressly provides for severance benefits to be in addition to those provided under the Plan). The severance payments and benefits to which a

ARTICLE VII 
 FEDERAL
EXCISE TAX UNDER SECTION 4999 OF THE CODE IN CONNECTION WITH A CHANGE IN CONTROL 
 Section 7.01 Adjustments to
Payments. Anything in this Plan to the contrary notwithstanding, if (a) it is determined that any payment or distribution by the Company to the Participant or for the Participant’s benefit (whether paid or payable or distributed or
distributable pursuant to the terms of this Plan or otherwise) (the “Payments”) would be subject to the excise tax imposed by Section 4999 (or any successor provisions) of the Code, or (b) any interest or penalty is
incurred by the Participant with respect to such excise tax (such excise tax, together with any such interest and penalties, is hereinafter collectively referred to as the “Excise Tax”), then the Payments shall be reduced (but not
below zero) if and to the extent that such reduction would result in the Participant retaining a larger amount, on an after-tax basis (taking into account federal, state and local income taxes and the
imposition of the Excise Tax), than if the Participant received all of the Payments. The Company shall reduce or eliminate the Payments by first reducing or eliminating the portion of the Payments which are not payable in cash and then by reducing
or eliminating cash payments, in each case in reverse order beginning with payments or benefits which are to be paid the farthest in time from the determination. 

Section 7.02 Determinations. All determinations required to be made under this Article VII, including whether and when an
adjustment to any Payments is required and, if applicable, which Payments are to be so adjusted, shall be made by an independent accounting firm selected by the Company from among the four largest accounting firms in the United States or any
nationally recognized financial planning and benefits consulting company (the “Accounting Firm”) which shall provide detailed supporting calculations both to the Company and the applicable Participant at such time as may be
requested by the Company, or earlier within 15 business days of the receipt of notice from the Participant that there has been a Payment. If the Accounting Firm that the Company selects is serving as accountant or auditor for the individual, entity
or group effecting the Change in Control, the Company shall appoint another nationally recognized accounting firm to make the determinations required hereunder (which accounting firm shall then be referred to as the Accounting Firm hereunder). All
fees and expenses of the Accounting Firm shall be borne solely by the Company. If the Accounting Firm determines that no Excise Tax is payable by a Participant, it shall furnish the Participant with a written opinion that failure to report the
Excise Tax on the Participant’s applicable federal income tax return would not result in the imposition of a negligence or similar penalty. Any determination by the Accounting Firm shall be binding upon the Company and the Participant.

Section 8.03 Successors’ Binding Obligation. The Plan will be binding upon any successor to the Corporate
Parent, its assets, its businesses or its interest (whether as a result of the occurrence of a Change in Control or otherwise), in the same manner and to the same extent that the Corporate Parent would be obligated under the Plan if no succession
had taken place. In the case of any transaction in which a successor would not by the foregoing provision or by operation of law be bound by the Plan, the Corporate Parent shall require any successor to the Corporate Parent to expressly and
unconditionally assume the Plan in writing and honor the obligations of the Corporate Parent and any applicable Affiliates hereunder, in the same manner and to the same extent that the Corporate Parent and such Affiliates would be required to
perform if no succession had taken place. All payments and benefits that become due to a Participant under the Plan will inure to the benefit of his or her heirs, assigns, designees or legal representatives. 

Section 8.04 No Assignment or Transfer; Beneficiaries; Unfunded Obligations. Except as otherwise determined by the
Plan Administrator, benefits payable under this Plan shall not be assignable or transferable by the Participant, and shall not be subject in any manner to assignment, alienation, pledge, encumbrance or charge. Notwithstanding the foregoing, in the
event of the death of a Participant, except as otherwise provided by the Plan Administrator, benefits earned but unpaid under this Plan shall become payable to the Participant’s beneficiary as designated by the Participant in the manner
prescribed by the Plan Administrator or, in the absence of an authorized beneficiary designation, by a legatee or legatees of the Participant’s Plan benefit under the Participant’s last will or by such Participant’s executors,
personal representatives or distributees of such Plan benefit in accordance with the 

  
 13 

 
Participant’s will or the laws of descent and distribution. The amounts to be paid to Participants under the Plan are unfunded obligations of the Company. The Company is not required to
segregate any monies or other assets from its general funds with respect to these obligations. Participants shall not have any preference or security interest in any assets of the Company other than as a general unsecured creditor. 

Section 8.05 Compensation Recoupment. All awards, amounts or benefits received or outstanding under this Plan shall
be subject to clawback, cancellation, recoupment, rescission, payback, reduction or other similar action in accordance with any Company clawback or similar policy or any applicable law related to such actions. Each Participant shall be deemed to
have acknowledged and consented to the Company’s application, implementation and enforcement of any applicable Company clawback or similar policy that may apply to the Participant, whether adopted before or after the Effective Date, and any
applicable law relating to clawback, cancellation, recoupment, rescission, payback, or reduction of compensation, and the Company may take any actions that may be necessary to effectuate any such policy or applicable law, without further
consideration or action. 
 Section 8.06 Notice. 

(a) For purposes of this Plan, all notices and other communications required or permitted hereunder shall be in writing and shall be deemed to
have been duly given when received if delivered by hand, recognized expedited courier service, or email, postage and other fees prepaid, addressed as follows: 

If to the Participant: 
 To the
most recent address or email address of the Participant set forth in the personnel records of the Company 
 If to the Company: 

II-VI Incorporated 

5000 Ericsson Drive 
 Warrendale,
PA 15806 
 Attention: Chief Legal Officer 

Email: ChiefLegalOfficer@II-VI.com 

or to such other address as either party may have furnished to the other in writing in accordance herewith. 

(b) A written notice of the Participant’s Date of Termination by the Company or the Participant, as the case may be, to the other, shall
(i) indicate the specific termination provision in this Plan relied upon, (ii) to the extent applicable, set forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of Participant’s employment
under the provision so indicated, and (iii) specify the Date of Termination. In the case of a termination by the Company other than a termination for Cause, the Date of Termination shall not be less than 30 days after the notice of termination
is given. In the case of a termination by the Participant, the Date of Termination shall be the 

  
 14 

 
date that the cure period contemplated under Section 1.01(aa) has expired if the Company has failed to remedy within such period the circumstances constituting Good Reason. The failure by
the Participant or the Company to set forth in such notice any fact or circumstance which contributes to a showing of Good Reason or Cause shall not waive any right of the Participant or the Company, or preclude the Participant or the Company, from
asserting such fact or circumstance in enforcing the Participant’s or the Company’s rights hereunder. 

Section 8.07 Governing Law; Validity. The interpretation, construction and performance of the provisions of this
Plan shall be governed by and construed and enforced in accordance with the internal laws of the Commonwealth of Pennsylvania without regard to conflicts of law principles, to the extent Pennsylvania laws are not preempted by ERISA. The invalidity
or unenforceability of any provision of this Plan shall not affect the validity or enforceability of any other provision of this Plan, which other provisions shall remain in full force and effect. 

Section 8.08 Waiver. No provision of this Plan may be waived unless such waiver is agreed to in writing and signed
by the Participant and by a duly authorized officer of the Company. No waiver by one party of the other party’s of a breach of, or failure to comply with,, a condition or provision of this Plan shall be deemed a waiver of similar or dissimilar
provisions or conditions at the same or at any prior or subsequent time. Failure by the Participant or the Company to insist upon strict compliance with any provision of this Plan or to assert any right the Participant or the Company may have
hereunder, including without limitation, the right of the Participant to terminate employment for Good Reason, shall not be deemed to be a waiver of such provision or right, or of any other provision or right. 

Section 8.09 Code Section 409A. Notwithstanding any provision of the Plan to the contrary, the
Plan and any payments provided hereunder are intended to comply with, or be exempt from, Code Section 409A. The Plan shall in all respects be interpreted, operated, and administered in accordance with this intent. Payments provided under the
Plan may only be made upon an event and in a manner that complies with Code Section 409A or an applicable exemption, including, to the maximum extent possible, exemptions for separation pay due to Separation from Service and/or short-term
deferrals. Any payments provided under the Plan to be made upon a Participant’s termination of employment with the Company that constitute deferred compensation subject to Code Section 409A shall only be made if such termination of service
constitutes a Separation from Service. Each installment payment provided under the Plan shall be treated as a separate identified payment for purposes of Code Section 409A. The Company makes no representations or warranties that the payments
provided under the Plan comply with, or are exempt from, Code Section 409A, and in no event shall the Company be liable for any portion of any taxes, penalties, interest, or other expenses that may be incurred by a Participant on account of non-compliance with Code Section 409A. If a Participant is a “specified employee” under Code Section 409A at his or her Date of Termination, to the extent necessary to avoid the imposition of any
additional taxes under Code Section 409A, any payments to be made upon the Participant’s Separation from Service that constitute deferred compensation subject to Code Section 409A and that are scheduled to be made within six months
following the Participant’s Date of Termination shall be delayed, without interest, and paid in a lump sum on the earlier of (i) the first payroll date to occur following the six month anniversary of the Participant’s Date of
Termination, or (ii) the Participant’s death, and any payments otherwise scheduled to be made thereafter shall be made in accordance with their original schedule. 

  
 15 

 Section 8.10 No Right to Continued Employment. Neither the
establishment of the Plan, nor any modification of it, and no creation of any fund, trust or account, or payment of any benefits, will be construed as giving any Participant, or any other person, the right to be retained in the service of the
Company, and all Participants will remain subject to discharge to the same extent as if the Plan had never been adopted. 
 ARTICLE IX

 CLAIMS, INQUIRIES, APPEALS 

Section 9.01 Applications for Benefits and Inquiries. Any application for benefits, inquiries about the Plan, and
inquiries about present or future rights under the Plan must be submitted to the Plan Administrator in writing, addressed to the Company in accordance with the notice provisions set forth in the Plan. 

Section 9.02 Denial of Claims. If any application for benefits is denied in whole or in part, the Plan Administrator
must notify the applicant, in writing, of the denial, and of the applicant’s right to review the denial. The written notice of denial will be set forth in a manner designed to be understood by the Participant, and will include specific reasons
for the denial, specific references to the Plan provision upon which the denial is based, a description of any information or material that the Plan Administrator needs in order to complete the review, and an explanation of the Plan’s review
procedure. 
 This written notice will be given to the Participant within 30 days after the Plan Administrator receives the application,
unless special circumstances require an extension of time, in which case, the Plan Administrator has up to an additional 30 days for processing the application. If an extension of time for processing is required, written notice of the extension will
be furnished to the applicant before the end of the initial 30 day period. 
 This notice of extension will describe the special
circumstances necessitating the additional time and the date by which the Plan Administrator is to render his or her decision. If written notice of denial of the application for benefits is not furnished within the specified time, the application
will be deemed to be denied. The applicant will then be permitted to appeal the denial in accordance with the review procedure described below. 

Section 9.03 Request for a Review. Any person (or that person’s authorized representative) for whom an
application for benefits is denied (or deemed denied), in whole or in part, may (but is not required to) appeal the denial by submitting a request for a review to the Plan Administrator within 60 days after the application is denied (or deemed
denied). The Plan Administrator will give the applicant (or his or her representative) an opportunity to review pertinent documents in preparing a request for a review. A request for a review must be in writing and addressed to the Company in
accordance with the notice provisions set forth in the Plan. 

  
 16 

 A request for review must set forth all of the grounds on which it is based, all facts in
support of the request, and any other matters that the applicant feels are pertinent. The Plan Administrator may require the applicant to submit additional facts, documents or other material the Plan Administrator deems necessary or appropriate in
connection with his or her review. 
 Section 9.04 Decision on Review. The Plan Administrator will act on each
request for review within 20 days after receipt of the request, unless special circumstances require an extension of time (not to exceed an additional 20 days). If an extension for review is required, written notice of the extension will be
furnished to the applicant within the initial 20-day period. The Plan Administrator will give prompt, written notice of his or her decision to the applicant. If the Plan Administrator confirms the denial of
the application for benefits in whole or in part, the notice will outline, in a manner calculated to be understood by the applicant, the specific Plan provisions on which the decision is based. If written notice of the Plan Administrator’s
decision is not given to the applicant within the time prescribed in this Section 9.04, the application will be deemed denied on review. 

Section 9.05 Rules and Procedures. The Plan Administrator may establish rules and procedures, consistent with the
Plan and with ERISA, that are necessary or appropriate in carrying out his or her responsibilities in reviewing benefit claims. The Plan Administrator may require an applicant who wishes to submit additional information in connection with an appeal
to do so at the applicant’s own expense. 
 Section 9.06 Exhaustion of Remedies. No claim for benefits under
the Plan may be brought in any forum until the claimant (a) has submitted a written application for benefits in accordance with the procedures described by Section 9.01, (b) has been notified by the Plan Administrator that the application
is denied (or the application is deemed denied due to the claims administrator’s failure to act within the established time period), (c) has filed a written request for a review of the application in accordance with the appeal procedure
described in Section 9.03, and (d) has been notified in writing that the Plan Administrator has denied the appeal (or the appeal is deemed to be denied under Section 9.04). 

Section 9.07 Final Dispute Resolution; Limitations on Legal Action. 

(a) General. Except as provided in Section 9.07(c) below, all claims and disputes under this Plan (including but not limited to
claims and disputes regarding interpretation, scope, or validity of the Plan, and any pendant state claims not preempted by ERISA) must follow the claims procedures described in Sections 9.01 through 9.06, before a claimant may take action in any
other forum regarding a claim for benefits under the Plan. Any action initiated by a claimant under the Plan must be brought within one year of a final determination on the claim, or the claim will be deemed permanently waived and abandoned, and the
claimant will be precluded from reasserting it. 
 (b) Claims for Benefits. After following the claims procedures described in
Sections 9.01 through 9.06, the following provisions apply to any further disputes, claims, questions or disagreements that may arise regarding this Plan. Except to the extent set forth in Section 9.07(c), any such dispute shall be finally
settled by arbitration conducted expeditiously in accordance with the rules of the American Arbitration Association by three independent and impartial arbitrators. Each party shall appoint one arbitrator, and the two arbitrators so appointed shall
appoint the third. The arbitration shall be conducted 

  
 17 

 
in English, and shall be governed by the United States Arbitration Act, 9 U.S.C. §§ 1-16, and judgment on the award rendered by the arbitrators
may be entered by any court having jurisdiction. The place of arbitration shall be Pittsburgh, Pennsylvania. The arbitrators are not empowered to award damages in excess of economic and compensatory damages. 

(c) Injunctive Relief. Notwithstanding any provision in the Plan to the contrary, if a Participant violates a covenant contained in
Section 6 and the Company would be caused immediate, material and irreparable harm for which money damages might not be adequate compensation, the Company shall be entitled to injunctive or other equitable relief in addition to any other
remedies provided by law, in equity or otherwise. The Restricted Period applicable to the Participant shall be extended by any period of time in which the Participant is in breach of the covenants contained in Section 6 and for any period of
time necessary to secure an order of court or injunction, either temporary or permanent, to enforce any of the covenants contained in Section 6.

 EXHIBIT A 

GENERAL RELEASE AGREEMENT 

This General Release Agreement (this “Agreement”) is made and entered into by ___________________ (“Executive” or
“Your” or “Your”) (collectively, referred to in this Agreement as “Executive”) and II-VI Incorporated, any parent, subsidiary, affiliate, successor, predecessor or
otherwise related companies, and the past, present, and future employees, agents, officers, attorneys, directors, shareholders, members, managers and executive benefit programs of any of them, and their agents and insurers (collectively, referred to
in this Agreement as “II-VI” or the “Company”). This Agreement shall become effective upon the signing of this Agreement by You or, if applicable, as defined in
Section 9.2 below. 
 In consideration of the severance pay and benefits provided to Executive as set forth in the II-VI Incorporated’s Executive Severance Plan (the “Severance Plan”), as well as any promises set forth in this Agreement, Executive agrees as follows: 

1. Release of Claims. 
 1.1 In exchange for the
Company providing You with the payments and other benefits set forth in the Severance Plan, You, and Your spouse, attorneys, heirs, dependents, beneficiaries, executors, administrators, successors, and assigns, hereby unconditionally release and
completely and forever discharge the Company, on behalf of and for the benefit of itself, all related corporate entities and partnerships, and each of their past, present and future employees, officers, directors, attorneys, owners, partners,
members, insurers, benefit plan fiduciaries and agents, and all of their respective successors and assigns (“Released Parties”), from any and all rights, claims, causes of action, or lawsuits whether known or unknown, that
you ever had, now have, or may have against any or all of the Released Parties up to the date of execution of this Agreement including, without limitation, any and all claims you had, have, or may have arising out of or relating to your employment
with the Company or the separation of that employment, for any and all reasons. 
 You specifically release Released Parties from any rights
or claims that you may have based upon the Employee Retirement Income Security Act, Title VII of the Civil Rights Act of 1964, the Americans With Disabilities Act of 1990, the Age Discrimination in Employment Act of 1967, the Equal Pay Act, the
Family and Medical Leave Act, Sections 1981 through 1988 of U.S.C. Title 42, all as amended, and any rules or regulations under such laws and authorities; all Pennsylvania employment discrimination laws, including but not limited to the Pennsylvania
Human Relations Act; the Pennsylvania Equal Pay Act; the Pennsylvania Minimum Wage Act; the Pennsylvania Wage Payment and Collection Law; Pennsylvania statutes regarding whistleblower protection, personnel Files, criminal records, wage complaints,
retaliation; all as amended together with all of their respective implementing regulations; and/or any other federal, state or local laws or regulations prohibiting employment discrimination or which otherwise regulate employment terms and
conditions. You also release the Released Parties from any claim for negligence, wrongful discharge, unfair treatment, defamation, breach of public policy, express or implied contract, or any other claims arising under common law that relate in any
way to your employment with the Company or the termination thereof. The foregoing description of claims is intended to be illustrative and is not exhaustive. The Parties intend this release to be a release of any and all claims to the fullest extent
permissible under law. This waiver and release is of Your rights to all remedies and damages available to You in law or equity, including but not limited to Your right to compensation, backpay, front pay,
non-economic damages, punitive and exemplary damages, statutory damages, attorneys’ fees, injunctive relief and declaratory judgments. This general release does not extend to claims which You do not know
or suspect exist at the time of executing the release, which if known by You would have materially affected Your entering into this Agreement with the Company. 

  
 19 

 1.2 Notwithstanding the release contained in Section 1.1, You do not waive
(i) Your entitlement to receive any 401(k), pension plan benefits, or Company ERISA-covered benefits that shall have vested (if any) as of the date You sign this Agreement to the extent You have any entitlement to those benefits under the terms
of the relevant plans, or (ii) Your right to file a charge with the EEOC or participate in an investigation conducted by the EEOC; however, You expressly waive Your right to monetary or other relief should any administrative agency, including
but not limited to the EEOC, pursue any claim on Your behalf. 
 1.3 The release contained in Section 1.1 above does not apply to any
claim or rights that may arise after that date You sign this Agreement or claims that the controlling law clearly states may not be released by private agreement. You also understand that You are not waiving Your rights to unemployment compensation.

 2.0 Covenant Not to Sue. 
 2.1 You
warrant that You do not have any complaint, charge or grievance against any Released Party pending before any federal, state or local court or administrative or arbitral agency, and You further covenant not to sue, file a lawsuit, or commence any
other proceeding, arbitral, administrative or judicial action, against any of the Released Parties in any court of law or equity, or before any arbitral body or administrative agency, with respect to any matter released in Section 1.1 above;
provided, however, that this covenant not to sue does not affect Your rights to enforce appropriately the terms of the Severance Plan in a court of competent jurisdiction and does not affect Your right to file a charge with the EEOC or participate
in an investigation conducted by the EEOC; however, You expressly waive Your right to monetary or other relief should any administrative agency, including but not limited to the EEOC, pursue any claim on Your behalf. Notwithstanding the foregoing,
nothing herein shall limit Your right to receive an award for information provided to the Securities and Exchange Commission. 
 Nothing in this Agreement
prohibits You from reporting possible violations of federal law or regulation to any governmental agency or entity, including but not limited to the Department of Justice, the Securities and Exchange Commission, the Congress, and any agency
Inspector General, or making other disclosures that are protected under the whistleblower provisions of federal law or regulation. You do not need the prior authorization of the Company to make any such reports or disclosures and You are not
required to notify the Company that You have made such reports or disclosures. 
 2.2 Should You file a lawsuit with any court concerning any
claim, demand, issue, or cause of action waived, released or discharged through this Agreement or otherwise in breach of Section 2.1 above, You agree (i) that any amounts payable or paid to You, as applicable, pursuant to Section 2 of
the Severance Plan shall no longer be payable and, if already paid, shall promptly be returned to the Company and (ii) to the fullest extent allowed by applicable law, to indemnify the Released Parties for all costs and expenses incurred by
them in defending such lawsuit. You further agree that nothing in this Agreement shall limit the right of a court to determine, in its sole discretion, that the Released Parties are entitled to restitution, recoupment or set off of any monies paid
should the release of any claims under this Agreement subsequently be found to be invalid. 

  
 20 

 2.3 You agree not to advocate or incite the institution of, or assist or participate in, any
suit, unrest, complaint, charge or administrative proceeding by any other person against any of the Released Parties, unless compelled by legal process to do so. Nothing in this Section 2 shall prohibit any Party from lawfully participating or
cooperating in an investigative proceeding of any federal, state or local government agency. 
 3.0 Non-Admission
of Liability. You agree that this Agreement shall not in any way be construed as an admission that any of the Released Parties owe You any money or have acted wrongfully, unlawfully, or unfairly in any way towards You. In fact, You understand
that the Released Parties specifically deny that they have violated any federal, state or local law or ordinance or any right or obligation that they owe or might have owed to You at any time, and maintain that they have at all times treated You in
a fair, non-discriminatory and non-retaliatory manner. 
 4.0
Confidentiality of Agreement. You also acknowledge and agree that You shall not publicize, communicate, authorize or permit the publication or communication in any form whatsoever of the contents of this Agreement or the events giving rise
thereto, except to Your immediate family, Your financial advisors and/or legal counsel, or where required by law. 
 5.0 Representations and
Indemnification. 
 5.1 You represent to the company that You will abide by any and all post-employment restrictive covenants You signed
or entered into in connection with Your employment, including but not limited to, covenants relating to competition, solicitation or hiring of employees, solicitation of customers, and confidentiality. 

5.2 You agree that You will indemnify and hold the Released Parties harmless from any loss, cost, damage or expense (including attorneys’
fees) incurred by the Released Parties arising out of Your breach of any portion of this Agreement or any post-employment restrictive covenant You signed or entered into in connection with Your employment. You also agree and understand that Your
entitlement to and retention of the Severance Benefits the Company has agreed to provide to You are expressly conditioned upon Your fulfillment of Your promises herein and any applicable post-employment restrictive covenants, and You agree that if
You breach this Agreement or any applicable post-employment restrictive covenants that any amounts payable or paid to You, as applicable, pursuant to the Severance Plan, shall no longer be payable and, if already paid, shall promptly be returned to
the Company within seven days of the Company providing you with written notice of Your breach of any provision of this Agreement or any applicable post-employment restrictive covenants, to the extent permitted or required by law. The Company shall
determine whether a breach has occurred in its sole discretion and under any applicable law or regulation.

accordance with, the laws of the Commonwealth of Pennsylvania, without reference to conflict of laws principles. Any action relating to this Agreement must be instituted in the courts of Butler County, Pennsylvania, or the federal courts of the
Western District of Pennsylvania. The Company and Employee hereby consent to the jurisdiction of such courts and waive any right or defense relating to venue or jurisdiction.
