SEPARATION AGREEMENT

August 14, 2018

Jan Kees van Gaalen

Dear Jan Kees:

This letter agreement (“Separation Agreement”) is provided to confirm the terms of your separation from employment with Kennametal Inc. (“Company”). The Company advises you to consult with an attorney regarding this Separation Agreement, which includes the Company’s consideration it shall pay you in exchange for a release of claims, as per Section 4(a) and Section 15 of your Officer’s Employment Agreement effective September 1, 2015 (“Officer’s Employment Agreement”).

1.      Termination of Officer Status and Employment with the Company.

Your status as Vice President and Chief Financial Officer and employment with the Company will terminate without cause effective September 7, 2018 (“Termination Date”). On the Termination Date, you will cease to perform any duties or responsibilities of your former position as Vice President and Chief Financial Officer. As such, you are not authorized to make any commitments on behalf of the Company or otherwise bind or obligate the Company, nor are you authorized to represent to others (directly or by implication) that you have any such authority.

Your Officer’s Employment Agreement will terminate on the Termination Date concurrent with your employment, except for your continued obligations under the terms of paragraph 9 concerning confidential information and non-disclosure (which are reincorporated herein as if set forth in full). You acknowledge and agree that no “Change of Control” as defined under the Officer’s Employment Agreement has occurred. Your designation as an “executive officer” of the Company for purposes of the Securities Exchange Act of 1934, as amended, shall also cease on your Termination Date or such earlier date as determined by the Kennametal Board of Directors, but the Company’s Insider Trading Policy, as well as all other applicable Company policies and procedures, will continue to apply to you in accordance with their terms.

Notwithstanding your termination of employment and officer status, the Company acknowledges and agrees that the obligations set forth under the Indemnification Agreement dated September 1, 2015 between you and the Company remain in full force and effect according to the terms of that agreement.

2.        Compensation and Benefits.

In accordance with the terms and conditions of your employment with the Company, the following sets forth the compensation and benefits you are entitled to and will receive. You are not entitled to any compensation or benefits not otherwise set forth in this Section 2.

This represents full payment of all of your PTO as of the termination of your employment. You will not earn any PTO or pay after your Termination Date, and you will not receive any further payment for earned and unused PTO. In the event you have used more PTO than you have earned up to your Termination Date, you authorize the Company to withhold from the separation benefit payments, which are to be paid in accordance with Section 3, an amount equal to the unearned PTO taken.

(c)        Active Benefits: Subject to your current elections, you will continue to receive active coverage for medical, dental, and vision benefits through the last day of the month in which your employment terminates. Coverage for life, AD&D, and disability will end effective on your Termination Date.

(d)        COBRA Benefits: After your healthcare coverage as an active employee ends, you and your dependents have the right to continue your group health care coverage under the Consolidated Omnibus Budget Reconciliation Act (“COBRA”), by paying the applicable premium, for a period of time (usually 18 months). You will receive information about this benefit continuation under separate cover from Business Solver, Kennametal’s third party COBRA administrator.

3.        Separation Benefits

Consistent with the terms of your Officers Employment Agreement, the Company asks that you sign this Separation Agreement to obtain the compensation described in this Section 3 and to effectuate the release of claims set forth in Section 4. In exchange for your execution of this release, and upon your signing this Separation Agreement (without revoking it, as provided herein) and it becoming effective, the Company will provide you:

(a) Severance: For the twelve (12) month period beginning on September 7, 2018 and ending on September 6, 2019, you will receive severance pay in the form of salary continuation payments, at the rate of your current base salary ($556,200 per year), in substantially equal installments (at least monthly) in accordance with the Company’s established payroll practices, subject to required and authorized withholdings and deductions.

3

(b) Additional Severance: The Company will pay to you a lump sum cash payment equal to $600,000, which represents 50% of your ERP vested amount on the vesting date of December 2, 2018. This amount will be paid as a total lump sum payment six (6) months following the Termination Date, subject to required and authorized withholdings and deductions in accordance with IRC 409A.

The following disclosure pertains to Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and how it may affect payments of deferred compensation under this Separation Agreement. The Code governs the taxation of deferred compensation, and contains provisions that accelerate income recognition and impose interest and additional taxes on payments and awards subject to Code Section 409A that fail to conform or are modified inconsistent with the requirements of Code Section 409A. You should review the content of this Agreement, specifically this paragraph 3, with your attorney and/or tax advisor for Section 409A compliance. You are solely liable for all tax, interest and penalties that might be imposed under Section 409A. The Company agrees to discuss modifying the terms of this paragraph 3 at your request, if necessary, to comply with the requirements of Section 409A and the regulations promulgated thereunder. Such request must be made within 21 days from the date of this letter. For purposes of this Agreement, each payment is intended to be excepted from Section 409A to the maximum extent provided under Section 409A as follows: each severance payment, including each individual installment payment, shall be treated as a separate payment. Each payment under this Agreement is intended to be excepted from Section 409A to the maximum extent provided under Section 409A as follows: (i) each payment made within the applicable 2 ¹⁄₂ month period specified in Treas. Reg. § 1.409A-1(b)(4) is intended to be excepted under the short-term deferral exception as specified in Treas. Reg. § 1.409A-1(b)(4); (ii) post-termination medical benefits are intended to be excepted under the medical benefits exceptions as specified in Treas. Reg. § 1.409A-1(b)(9)(v)(B); and (iii) to the extent payments are made as a result of an involuntary separation, each payment that is not otherwise excepted under the short-term deferral exception or medical benefits exception is intended to be excepted under the involuntary pay exception as specified in Treas. Reg. § 1.409A-1(b)(9)(iii). You shall have no right to designate the date of any payment hereunder. With respect to payments subject to Section 409A of the Code (and not excepted therefrom), if any, it is intended that each payment is paid on permissible distribution event and at a specified time consistent with Section 409A of the Code.

4.        Your Release of Claims.

By signing this Separation Agreement and accepting the compensation set forth in Section 3, you, on behalf of yourself, your heirs, executors, administrators, successors and assigns, waive, release and forever discharge the Company and all current and former subsidiaries, divisions, related or affiliated companies, and all of their officers, directors, employees, agents, successors, predecessors and assigns, including but not limited to all management and supervisory employees (severally and collectively “Releasees”), jointly and individually, from all claims, complaints, demands, causes of action, obligations, liabilities and damages of every nature and description, known or unknown, foreseen or unforeseen, in law or equity, at common law or under any statute, rule, regulation, order or law, whether federal, state or local, on any grounds whatsoever arising before your signing this Separation Agreement,

4

including but not limited to any claim relating to or arising out of your employment by the Company or the Company’s involuntary termination of your employment, any claim under the WARN Act, any claim under the Age Discrimination in Employment Act of 1967, as amended, any claim of discrimination on any basis under any federal, state or local law, any claim of breach of any express or implied contract, any claim for promissory estoppel or detrimental reliance, and any claim for wrongful or constructive discharge. If any administrative agency or court assumes jurisdiction of any charge, complaint, proceeding or action covered by Section 4 of this Separation Agreement against any of the Releasees, you agree not to accept, recover or receive any monetary damages or other relief from or in connection with such charge, complaint, proceeding or action. You agree that if a court of competent jurisdiction determines that you are to be awarded damages under WARN, those damages will be offset by the total compensation paid to you under Section 3(a) and 3(b) of this Separation Agreement.

The Company advises you to consult with your own attorney before agreeing to the release of claims set forth in this section. As set forth below in Section 12, you have twenty-one (21) days from the date of your receipt of this letter to review this Separation Agreement and the release it contains.

Nothing in this section impairs your right to vested Company benefits to which you are entitled as of the date you sign this Separation Agreement. Nothing in this section impairs any right you hold that cannot be waived or released as a matter of law. By way of example, nothing in this section impairs your right to file a charge or complaint with any appropriate federal, state, or local agency, such as the United States Equal Employment Opportunity Commission, or to participate in or cooperate with any such charge or complaint procedure. After signing this Separation Agreement, you retain the right to challenge the validity of the Separation Agreement. If you have any questions about other rights you may hold that cannot be waived or released as a matter of law, the Company advises you to consult with your own attorney on that subject.

5.        Your Representations.

By signing this Separation Agreement and accepting the compensation set forth in Section 3, you represent and affirm that you have neither filed nor caused or permitted to be filed on your behalf any claim, charge, proceeding or action against any of the Releasees in any court or administrative agency for your benefit. Further, you represent and affirm that you are aware of no facts that would support the filing of any such claim, charge, proceeding or action. Further, you represent and affirm that, as of the date you signed this Separation Agreement, you were aware of no facts indicating that the Company, or any person or entity acting on its behalf, engaged in illegal or unethical conduct of any sort, and that you have not engaged in any such conduct. If you are unable to make these representations, you must contact the Company before signing this Separation Agreement. All of the representations contained in this Section 5 are material to the Company’s decision to offer the compensation set forth in Section 3, and the Company is acting in reliance on your representations when offering and providing these benefits.
