Dear Michael:

Ampco-Pittsburgh Corporation (the “Corporation”) recognizes your experience and potential contribution to the success of the Corporation and desires to assure the Corporation of your continued employment. In this connection, the Board of Directors of the Corporation (the “Board”) recognizes that, as is the case with other publicly held corporations, the possibility of a change in control may exist and that such possibility, and the uncertainty that it may raise among the Corporation’s management, may result in the departure or distraction of management personnel to the detriment of the Corporation and its stockholders.

The Board has determined that appropriate steps should be taken to reinforce and encourage the continued attention and dedication of members of the Corporation’s management, including you, to their assigned duties without distraction in the face of potentially disturbing circumstances arising from the possibility of a change in control of the Corporation.

In order to induce you to remain in the employ of the Corporation, the Corporation agrees that you shall receive the severance benefits set forth in this letter agreement (“Agreement”) in the event your employment with the Corporation is terminated subsequent to a “Change in Control” (as defined in Section 2 hereof) under the circumstances described below.

1. Term of Agreement . This Agreement will commence effective as of April 25, 2016 and shall continue in effect for twenty-four (24) months from such date; provided, however , that commencing on April 25, 2018 and on each anniversary thereafter, the term of this Agreement shall automatically be extended for one additional year unless, not later than thirty (30) days prior to such date, the Corporation shall have given notice that it does not wish to extend this Agreement; provided, further, however , that if a Change in Control shall have occurred during the original or extended term of this Agreement, this Agreement cannot be cancelled.

2. Change in Control .

(a) No benefits shall be payable hereunder unless there shall have been a Change in Control as set forth below. For purposes of this Agreement, a “Change in Control” shall be deemed to have occurred if:

(i) any “person” (as defined in Sections 13(d) and 14(d) of the Exchange Act) other than the persons or the group of persons in control of the Corporation on the date hereof is or becomes the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Corporation representing fifty percent (50%) or more of the combined voting power of the Corporation’s then outstanding securities;

(ii) within any period of two consecutive years (not including any period prior to the execution of this Agreement) there shall cease to be a majority of the Board comprised as follows: individuals who at the beginning of such period constitute the Board and any new director(s) whose election was approved by a vote of at least two-thirds (2/3) of the directors then still in office who either were directors at the beginning of the period or whose election or nomination for election was previously so approved;

(iii) the shareholders of the Corporation approve a merger of, or consolidation involving, the Corporation in which (A) the Corporation’s Common Stock, par value $1.00 per share (such stock, or any other securities of the Corporation into which such stock shall have been converted through a reincorporation, recapitalization or similar transaction, hereinafter called “Common Stock of the Corporation”), is converted into shares or securities of another corporation, or into cash or other property, or (B) the Common Stock of the Corporation is not converted as described in Clause (A), but in which more than forty percent (40%) of the Common Stock of the surviving corporation in the merger is owned by Shareholders other than those who owned such amount prior to the merger; or any other transaction after which the Corporation’s Common Stock is no longer to be publicly traded; in each case, other than a transaction solely for the purpose of reincorporating the Corporation in another jurisdiction or recapitalizing the Common Stock of the Corporation; or

(iv) the shareholders of the Corporation approve a plan of complete liquidation of the Corporation, or an agreement for the sale or disposition by the Corporation of all or substantially all the Corporation’s assets, either of which is followed by a distribution of all or substantially all of the proceeds to the shareholders.

For purposes of this Agreement, a “Potential Change in Control of the Corporation” shall be deemed to have occurred if (i) the Corporation enters into an agreement, the consummation

of which would result in the occurrence of a Change in Control, (ii) any person (including the Corporation) publicly announces an intention to take or to consider taking actions, which if consummated would constitute a Change in Control, or (iii) the Board adopts a resolution to the effect that, for purposes of this Agreement, a Potential Change in Control of the Corporation has occurred.

4. Termination Following a Change in Control .

(a) If any of the events described in Section 2 constituting a Change in Control shall have occurred, you shall be entitled to the benefits provided in Section 5(d) upon the termination of your employment within twenty-four (24) months after the Change in Control has occurred, or pursuant to Section 6 prior to the Change in Control, unless such termination is (i) because of your death or Disability, (ii) by the Corporation for Cause, or (iii) by you other than for Good Reason.

(b) For purposes of this Agreement, “Disability” shall mean that if, as a result of your incapacity due to physical or mental illness, you shall have been absent from the full-time performance of your duties with the Corporation for six (6) consecutive months, and within thirty (30) days after written notice of termination shall have been given to you, you shall not have returned to the full-time performance of your duties.

(c) For purposes of this Agreement, termination by the Corporation of your employment for “Cause” shall mean termination upon:

(i) the willful and continued failure by you to substantially perform duties consistent with your position with the Corporation (other than any such failure resulting from incapacity due to physical or mental illness or termination by you for Good Reason), after a demand for substantial performance is delivered to you by the Board, together with a copy of the resolution of the Board that specifically identifies the manner in which the Board believes that you have not substantially performed your duties, which resolution must be passed by at least two-thirds (2/3) of the entire Board at a meeting called for the purpose and after an opportunity for you and your counsel to be heard by the Board, and you have failed to resume substantial performance of your duties on a continuous basis within fourteen (14) days of receiving such demand,

(ii) the willful engaging by you in conduct that is demonstrably and materially injurious to the Corporation, monetarily or otherwise, as set forth in a resolution of the Board, which resolution must be passed by at least two-thirds (2/3) of the entire Board at a meeting called for the purpose and after an opportunity for you and your counsel to be heard by the Board, or

(iii) your conviction of a felony, or conviction of a misdemeanor involving assets of the Corporation.

(d) For purposes of this Agreement, “Good Reason” shall mean, without your express written consent, the occurrence after a Change in Control of any one or more of the following conditions, which condition continues without timely and complete remedy by the Corporation after notice, as provided below:

(i) If, following a Change in Control, there is no Parent Corporation and your status as Chief Financial Officer of the Corporation shall not continue after such Change in Control or, if following a Change in Control, there is a Parent Corporation, as defined below, you shall not be Chief Financial Officer of the Parent Corporation, or, in either case, you shall not be afforded the authority, responsibilities and prerogatives of such position and report directly to the Chief Executive Officer of the Corporation or the Parent Corporation, as the case may be;

(ii) a reduction by the Corporation in your base salary as in effect immediately before the Change in Control, a failure to increase such base salary at the same intervals as prevailed before the Change in Control in an amount at least equal to the same percentage increase as the last increase prior to the Change in Control, or a reduction in bonus after the Change in Control over the last bonus paid before the Change in Control unless there are equivalent reductions in bonuses for all executives of the Corporation;

(iii) the requirement that you be based at a location in excess of twenty-five (25) miles from the location where you are currently based;

(iv) the failure by the Corporation to continue in effect any of the Corporation’s employee benefit plans, policies, practices or arrangements in which you participate or under which you are entitled to benefits, or the failure by the Corporation to continue your participation therein or benefits thereunder on substantially the same basis, both in terms of the amount of benefits provided and the level of your participation relative to other participants, as existed immediately prior to the Change in Control; or

(v) the breach of this Agreement by the Corporation because of the Corporation’s failure to obtain a satisfactory agreement from any successor to the Corporation to assume and agree to perform this Agreement, as contemplated in Section 7.

The foregoing notwithstanding, you shall notify the Corporation within 90 days of the initial existence of a particular condition described above in this Section 4(d), and the Corporation shall have 30 days from such notice completely to remedy such particular condition so that the you are in the same position as if the condition had never occurred. If the Corporation timely and completely remedies the condition as required above, then the particular occurrence of the particular condition for which you gave notice shall no longer constitute Good Reason. If the Corporation does not timely and completely remedy the particular occurrence of the particular condition for which you gave notice, you shall be deemed to terminate employment for Good Reason on the 31st day following your notice to the Corporation.

(e) For purposes of this Agreement, “Parent Corporation” shall mean any “affiliate” of the Corporation that is the ultimate controlling entity of the Corporation or its

(f) “Good Reason” may be established notwithstanding your possible incapacity due to physical or mental illness, provided that Disability has not been established pursuant to Section 4(b). Your continued employment following the Change in Control shall not constitute a waiver of any rights hereunder including, but not limited to, rights with respect to any circumstance constituting Good Reason or rights under Section 7.

5. Compensation Upon Termination or During Incapacity . Following a Change in Control, upon termination of your employment, or during a period of incapacity but before termination for Disability, you shall be entitled to the following benefits:

(a) During any period prior to termination for Disability in which you fail to perform your full-time duties with the Corporation as a result of incapacity due to physical or mental illness, you shall continue to receive your Base Salary at the rate in effect at the commencement of any such period. Following termination for Disability, your benefits shall be determined in accordance with the Corporation’s retirement, insurance and other applicable programs and plans then in effect.

(b) If your employment shall be terminated by the Corporation for Cause or by you other than for Good Reason, the Corporation shall pay to you your full Base Salary through the date of termination of your employment at the rate then in effect, plus all other amounts to which you are entitled under any compensation or benefit plans of the Corporation at the time such amounts are due, and the Corporation shall have no further obligations to you under this Agreement.

(c) If your employment terminates by reason of your death, your benefits shall be determined in accordance with the Corporation’s retirement, survivor’s benefits, insurance and other applicable programs and plans then in effect.

(C) in lieu of shares of common stock of the Corporation (“Shares”) issuable upon exercise of outstanding options (“Options”), if any, granted to you under the Corporation’s Incentive Stock Option Plan, or under any additional, substitute or successor option program or plan as may be in effect from time to time (which Options shall be cancelled upon the making of the payment referred to below), you shall receive an amount in cash equal to the product of (i) the higher of the closing price per Share as reported on the New York Stock Exchange on the date of termination of your employment or the highest price per Share actually paid in connection with any Change in Control, over the exercise price per Share of each Option held by you, times (ii) the number of Shares covered by each such option;

(D) as more completely described in Section 5(i), for a twenty-four (24) month period after such termination, the Corporation will arrange to provide you at the Corporation’s expense with benefits under the Corporation’s health, dental, disability, life insurance, and other similar employee benefit insurance plans applicable to salaried employees, or benefits substantially similar to the benefits you were receiving under such plans immediately prior to the termination of your employment;

(E) the opportunity to purchase the leased Corporation car, if any, which has been assigned to you, at its then book value under the Corporation’s leasing arrangements, provided that should you choose to take such opportunity, you must complete such purchase by a date that is within two and one-half months after the calendar year of your termination;

(F) any unearned Restricted Stock Units granted to you under the any Stock Incentive Plan of the Corporation approved by the shareholders shall become immediately earned and vested as of the date of the termination of your employment; and

(G) all benefits payable to you under any defined benefit or retirement plan in effect at the time of such termination, in accordance with the terms and provisions of such plan.

(e) Anything in this Agreement to the contrary notwithstanding, in the event it shall be determined that any payment or distribution by the Corporation to you or for your benefit (whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise) (the “Payments”) would be subject to the excise tax imposed by Section 4999 (or any successor provisions) of the Internal Revenue Code of 1986, as amended (the “Code”), or any interest or penalty is incurred by you with respect to such

Page | 7

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 you 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 you received all of the Payments. The Corporation 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. All determinations required to be made under this Section 5(e), 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 accounting firm selected by the Corporation (the “Accounting Firm”) which shall provide detailed supporting calculations both to the Corporation and to you within fifteen (15) business days of the receipt of notice from you that there has been a Payment, or such earlier time as is requested by the Corporation. In the event that the Accounting Firm is serving as accountant or auditor for the individual, entity or group effecting the Change in Control, you 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 Corporation. If the Accounting Firm determines that no Excise Tax is payable by you, it shall furnish you with a written opinion that failure to report the Excise Tax on your 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 Corporation and you.

(f) The payments provided for in Sections 5(d)(A), (B) and (C) shall be made not later than the fifth day following your termination of employment pursuant to the provisions of Section 5(d); provided, however , that if the amounts of such payments cannot be finally determined on or before such day, the Corporation shall pay to you on such day an estimate as determined in good faith by the Corporation of the minimum amount of such payments and shall pay the remainder of such payments (together with interest at the rate provided in Section 1274(b)(2)(B) of the Code) as soon as the amount thereof can be determined, but in no event later than the thirtieth day after the date of such termination. Such payments will be made in all events within 2-1/2 months following the calendar year in which such termination of employment occurred. If the amount of the estimated payments exceeds the amount subsequently determined to have been due, such excess shall constitute a loan by the Corporation to you payable on the fifth day after demand by the Corporation (together with interest at the rate provided in Section 1274(b)(2)(B) of the Code).

(g) The Corporation shall also pay to you all legal fees and expenses incurred by you as a result of, and related to, such termination of your employment by the Corporation for Cause, by the Corporation other than for Cause, or by you for Good Reason (including all such fees and expenses, if any, incurred in contesting or disputing any such termination or in seeking to obtain or enforce any right or benefit provided by this Agreement or in connection with any tax audit or proceeding to the extent attributable to the application of Section 4999 of the Code to any payment or benefit provided hereunder).

(h) You shall not be required to mitigate the amount of any payment provided for in this Agreement by seeking other employment or otherwise, nor shall the amount of any payment provided for in this Agreement be reduced by any compensation earned by you as the result of employment by another employer after the date of termination of your employment, or otherwise.

(i) With respect to the continuation of certain employee benefits for twenty-four (24) months pursuant to Section 5(d)(D), the following shall apply:

(A) During the 18-month COBRA Continuation Period, the Corporation will provide coverage as follows :

(i) If you elect COBRA Continuation Coverage, you shall continue to participate in all medical, dental and vision insurance plans you were participating in on the termination date, and the Corporation shall pay the entire applicable premium. During the COBRA Continuation Period, you shall be entitled to benefits on substantially the same basis and cost as would have otherwise been provided had you not separated from service. To the extent that such benefits are available under the above-referenced benefit plans and you had such coverage immediately prior to termination of employment, such continuation of benefits for you shall also cover your dependents for so long as you are receiving benefits under this Section 5. The COBRA Continuation Period for medical and dental insurance under this Section 5(i) shall be deemed to run concurrent with the continuation period federally mandated by COBRA (generally 18 months), or any other legally mandated and applicable federal, state, or local coverage period for benefits provided to terminated employees under the health care plan. For purposes of this Agreement, (1) “COBRA” means the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended, and (2) “COBRA Continuation Period” shall mean the continuation period for medical and dental insurance to be provided under the terms of this Agreement which shall commence on the first day of the calendar month following the month in which the date of your termination falls and generally shall continue for an 18 month period.

(ii) Following the conclusion of the 18-month COBRA Continuation Period, the Corporation will provide coverage as follows :

(1) If the relevant plan is self-insured (within the meaning of Section 105(h) of the Code), and such plan permits coverage for you, then the Corporation will continue to provide coverage under the plan for an additional eighteen (18) months and will annually impute income to you for the fair market value of the premium.

(2) If, however, any such plan does not permit the continued participation following the end of the COBRA Continuation Period as contemplated above, then the Corporation shall take all commercially reasonable efforts to provide you with, or assist you in obtaining, continued medical and dental coverage comparable to the coverage you had during the COBRA Continuation Period. It is specifically acknowledged by you that if such coverage is provided under a Corporation sponsored self-insured plan, it will be provided on an after- tax basis and you will have income imputed to you annually equal to the fair market value of the premium. If this coverage cannot be provided by the Corporation, (or where such continuation would adversely affect the tax status of the plan pursuant to which the coverage is provided), then as an alternative, the Corporation will reimburse you in lieu of such coverage an amount equal to your actual and reasonable cost of continuing comparable coverage.

(B) With respect to the continuation of disability, life insurance, and other similar employee benefit insurance plans applicable to salaried employees for twenty-four (24) months pursuant to Section 5(d)(D), the following shall apply:

(i) To the extent your coverage for disability, life insurance, and other similar employee benefit insurance plans applicable to salaried employees, cannot be provided under the Corporation’s insurance plans, the Corporation will reimburse you for your premium cost to obtain comparable insurances coverages.

(C) Reimbursement to you pursuant to Section 5(i)(A) or (B) above will be available only to the extent that (1) such expense is actually incurred for any particular calendar year and reasonably substantiated; (2) reimbursement shall be made no later than the end of the calendar year following the year in which such expense is incurred by you; (3) no reimbursement provided for any expense incurred in one taxable year will affect the amount available in another taxable year; and (4) the right to this reimbursement is not subject to liquidation or exchange for another benefit. Notwithstanding the foregoing, no reimbursement will be provided for any expense incurred following the thirty-six month period of benefit continuation or for any expense which relates to coverage after such date.

(j) Notwithstanding any provision of this Agreement to the contrary, to the extent that a payment hereunder is subject to Section 409A of the Code (and not excepted therefrom) and payable on account of your separation from service, such payment

shall be delayed for a period of six months after your termination date (or, if earlier, your death) if you are a Specified Employee (namely, a “key employee”, as defined in Section 416(i) of the Code without regard to paragraph (5) thereof, of the Corporation, as determined in accordance with the regulations issued under Code Section 409A and the procedures established by the Corporation). Any such payment that would otherwise have been due or owing during such six-month period will be paid immediately following the end of the six-month period in the month following the month containing the 6-month anniversary of your date of termination, together with interest at the rate provided in Section 1274(b)(2)(B) of the Code.

6. Notice of Termination Before a Change in Control . Notwithstanding any other provisions of this Agreement, if prior to a Change in Control there has been any statement made by the person (or an affiliate of such person) involved in such Change in Control to the effect that following such Change in Control any action or actions will be taken that would have the effect of creating a condition described in Section 4(d) that would permit you following a Change in Control to terminate your employment for Good Reason, and such statements have appeared in any proxy statement or other proxy soliciting materials, any tender offer, exchange offer, or prospectus or any other document or press release publicly issued or filed with the Securities and Exchange Commission or other governmental agency in connection with the contemplated Change in Control (including any such documents issued by the Corporation in which such statement is reported), then you shall have the right to notify the Corporation that, unless the condition that would constitute Good Reason is completely remedied prior to the effective date of the Change of Control, you intend to terminate your employment for Good Reason as of the effective date of the Change in Control, in which case your employment shall terminate on the effective date of the Change in Control and you shall be entitled to receive the payments due under Section 5(d) and (e) pursuant to the payment provisions described in Section 5(f).

7. Successors; Binding Agreement .

(a) The Corporation will require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Corporation or of any division or subsidiary thereof employing you to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Corporation would be required to perform if no such succession had taken place. Failure of the Corporation to obtain such assumption and agreement prior to the effectiveness of any such succession shall be a breach of this Agreement and shall entitle you to compensation from the Corporation in the same amount and on the same terms as you would be entitled hereunder if you terminated your employment for Good Reason, except that for purposes of implementing the foregoing, the date on which any such succession becomes effective shall be deemed to be the date of termination of your employment.

(b) This Agreement shall inure to the benefit of and be enforceable by your personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees.
