Lenders or the Junior Creditors, are hereinafter collectively referred to as the “Senior Creditor Obligations”); 

WHEREAS, as a condition precedent to the Senior Creditor’s and each Lender’s agreement to enter into the Credit Agreement and the
Other Documents, the Senior Creditor and the Lenders require that the Junior Creditor Obligations be subordinated to the Senior Creditor Obligations as and to the extent set forth herein; and 

WHEREAS, in order to induce the Senior Creditor and the Lenders to enter into the Credit Agreement and the Other Documents and to make
advances under the Credit Agreement, each Junior Creditor has agreed to subordinate the Junior Creditor Obligations to the Senior Creditor Obligations pursuant to and in accordance with the terms and conditions of this Subordination Agreement. 

NOW, THEREFORE, in consideration of the premises and mutual covenants contained herein, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto, intending to be legally bound hereby, agree as follows: 
 1. Unless otherwise defined herein, all
capitalized terms used herein shall have the meanings ascribed to them in the Credit Agreement. 

  
 - 2 - 

 2. Except as otherwise set forth in Section 3 hereof and the final sentence of
Section 6 hereof, no Junior Creditor will ask, demand, sue for, take or receive from any Loan Party, in any manner, without the consent of the Senior Creditor the whole or any part of any monies, now or hereafter owing by such Loan Party to
such Junior Creditor pursuant to the Junior Creditor Obligations until the Senior Creditor Obligations (other than indemnity and other contingent obligations) are paid in full and discharged and all commitments to make loans or otherwise make
advances or other extensions of credit under the Credit Agreement have been terminated. 
 3. So long as (i) no Default or Event of
Default under the Credit Agreement has occurred or will occur as a result thereof, Ampco-Pitt Corp. may make and the Junior Creditors may ask, demand, sue for, take, receive and retain for their own accounts (a) interest payments to the Junior
Creditors and (b) payments of reasonable fees, costs and expenses when due and payable in accordance, in each case of (a) and/or (b) above, with the Junior Creditor Documents, as such documents exist on March 3, 2016 (it being
understood and agreed that any amounts not paid as a result of the occurrence or potential occurrence of a Default or Event of Default, may be paid once such circumstance no longer exists whether as a result of cure, waiver or otherwise), and
(ii) in each case of (y) or (z) below, no Default or Event of Default under the Credit Agreement has occurred or will occur as a result thereof and the Loan Parties have demonstrated, in the manner provided for in the Credit
Agreement, compliance with the financial covenant contained in Section 6.5(b) of the Credit Agreement, Ampco-Pitt Corp. may, either (y) on or after the Maturity Date (as defined in the Junior Creditor Notes, as the same exists on
March 3, 2016), or (z) upon the occurrence of a Change in Control (as defined in the Junior Creditor Notes, as the same exists on March 3, 2016), in accordance with Section 3.4 of each applicable Junior Creditor Note, as such
document exists on March 3, 2016, pay, and the Junior Creditors may ask, demand, sue for, take, receive and retain for their own accounts, all outstanding and unpaid principal (including any applicable Make Whole Amount (as defined in the
Junior Creditor Notes, as the same exists on March 3, 2016)) due and payable to the Junior Creditors in accordance with the terms and provisions of the Junior Creditor Notes, as such documents exist on March 3, 2016. Neither the Credit
Agreement nor any document relating to the Senior Creditor Obligations may contain, or be amended or modified in any way to include, any provision which prohibits or restricts Ampco-Pitt Corp. from making a payment under the Junior Creditor
Obligations in the manner and subject to the limitations provided for under the express terms and provisions of this Section 3 and, for the avoidance of doubt, a payment in accordance with this Section 3 shall not itself constitute a
Default or an Event of Default under the Credit Agreement. For the avoidance of doubt, the payments expressly permitted by this Section 3 shall continue to be permitted notwithstanding any amendment, restatement, modification, supplement,
replacement, increase or refinancing of any nature in respect of the Credit Agreement or the Senior Creditor Obligations, including, without limitation, any such amendment, restatement, modification, supplement, replacement, increase or refinancing
of the nature described in Section 10 hereof or in clause (i) of Section 11 hereof, all as if such amendment, restatement, modification, supplement, replacement, increase or refinancing had not taken place. 

4. Senior Creditor shall promptly provide to the Junior Creditors and the Junior Creditors shall promptly provide to the Senior Creditor,
copies of any written notice of the occurrence or existence of an Event of Default or a default or event of default under any Junior Creditor Document, the Credit Agreement or any Other Document, as applicable; provided, however, in each
case, the failure to provide such notice shall not affect the validity of such notice, or create a cause of action against the party failing to give such notice, or create any claim 

  
 - 3 - 

 
or right on behalf of any third party. The sending or receipt of such notice shall not obligate the recipient to cure such default. The Loan Parties hereby consent and agree to the Senior
Creditor or the Junior Creditors providing any such information to the other and to such actions by the Senior Creditor and/or the Junior Creditors and waive any rights or claims against any Lenders or Junior Creditors arising as a result of such
information or actions. 
 5. Notwithstanding any right of the Junior Creditors with respect to the Junior Creditor Obligations but subject
to the provisions of Sections 2 and 3 hereof, all rights to payment and Liens, if any, of any of the Junior Creditors with respect to the Junior Creditor Obligations, whether now existing or hereafter arising and howsoever existing, in any assets of
any Loan Party shall be and hereby are subordinated to the rights and Liens of the Senior Creditor and until the Senior Creditor Obligations (other than indemnity and other contingent obligations) shall have been fully paid and satisfied, and all
commitments to make loans or otherwise make advances or other extensions of credit under the Credit Agreement have been terminated, no Junior Creditor shall have any right to possession of any such assets or to foreclose upon any such assets,
whether by judicial action or otherwise. In the event of (i) the occurrence of a Default or an Event of Default under the Credit Agreement or any of the Other Documents, (ii) any acceleration of any Junior Creditor Obligation or
(iii) any distribution, division or application (partial or complete), voluntary or involuntary, by operation of law or otherwise of all or any part of the assets of any Loan Party or the proceeds thereof to creditors of any Loan Party by
reason of the liquidation, dissolution or other winding up of any Loan Party’s business or in the event of any sale, receivership, insolvency or bankruptcy proceeding, or assignment for the benefit of creditors of any Loan Party, or any
proceeding by or against any Loan Party for any relief under any bankruptcy or insolvency law relating to the relief of creditors, readjustment of indebtedness, reorganizations, compositions or extensions, then and in any such event all of the
Senior Creditor Obligations (other than indemnity and other contingent obligations) shall first be paid in full, or payment thereof provided for in money or monies worth in accordance with the terms thereof, before any payment is made on account of
any Junior Creditor Obligations; and upon any such distribution, division or application, any payment or distribution of any kind or character, either in cash, securities or other property, which shall be payable or deliverable upon or with respect
to the Junior Creditor Obligations shall be paid or delivered directly to the Senior Creditor for application to the Senior Creditor Obligations until the Senior Creditor Obligations (other than indemnity and other contingent obligations) shall have
been fully paid and satisfied and all commitments to make loans or otherwise make advances or other extensions of credit under the Credit Agreement have been terminated. Notwithstanding anything to the contrary contained in Section 2, this
Section 5, Section 7 or otherwise in this Subordination Agreement, the Junior Creditors shall be entitled to receive and retain any distribution of Reorganization Subordinated Securities. For purposes of this Subordination Agreement,
“Reorganization Subordinated Securities” shall mean any (i) debt securities issued in substitution of or exchange for all or any portion of the Junior Creditor Obligations that are subordinated in right of payment, performance and
otherwise to the Senior Creditor Obligations to at least the same extent that the Junior Creditor Obligations are subordinated to the Senior Creditor Obligations pursuant to and in accordance with the terms and provisions of this Subordination
Agreement, and/or (ii) equity securities issued in substitution of or exchange for all or any portion of the Junior Creditor Obligations, provided, that if such equity securities provide for mandatory redemption or mandatory dividend or
distribution payments, the making and payment thereof shall be subordinated in right of payment, performance and 

  
 - 4 - 

 
otherwise to the Senior Creditor Obligations (or any equity securities issued in substitution of or exchange for all or any portion of the Senior Creditor Obligations) to at least the same extent
that the Junior Creditor Obligations are subordinated to the Senior Creditor Obligations pursuant to and in accordance with the terms and provisions of this Subordination Agreement. 

6. In the event of any bankruptcy, reorganization or insolvency proceeding, each Junior Creditor hereby irrevocably appoints the Senior
Creditor as its attorney-in-fact with full power to act in the place and stead of such Junior Creditor, in all matters relating to or affecting the Junior Creditor Obligations, for the purpose of protecting or preserving the Senior Creditor’s
rights under this Subordination Agreement, including for that purpose, the right to execute, verify, deliver and, upon the failure of such Junior Creditor to do so promptly, but in any event, prior to ten (10) days before the expiration of the
time to make, present, file and/or vote any such proof of claim, as applicable, to make, present, file and/or vote such proofs of claim, as applicable, against any Loan Party on account of all or any part of the Junior Creditor Obligations, as the
Senior Creditor may deem advisable and to receive and collect any and all distributions under any federal or state debtor relief statute on account of the Junior Creditor Obligations and to apply the same on account of the Senior Creditor
Obligations. Senior Creditor shall promptly provide the Junior Creditors with notice of any exercise by the Senior Creditor of the aforementioned power of attorney; provided, however, the failure to provide such notice shall not affect the
validity of any such action, or create a cause of action against the party failing to give such notice, or create any claim or right on behalf of any third party. Subject to the foregoing limitations, the Junior Creditors shall retain the right to
file, vote and otherwise act in any applicable bankruptcy proceeding in their capacity as such; provided, however, each Junior Creditor hereby acknowledges and agrees that it shall not file, vote or otherwise act as a creditor in a bankruptcy
proceeding in any manner that contravenes the terms and provisions of this Subordination Agreement. 
 7. Except as otherwise set forth in
Section 3 hereof and except as permitted in Section 5 hereof with respect to Reorganization Subordinated Securities, should any payment or distribution upon or with respect to the Junior Creditor Obligations or any security therefor or
proceeds thereof be received by any of the Junior Creditors prior to the satisfaction of all of the Senior Creditor Obligations (other than indemnity and other contingent obligations), each such Junior Creditor shall forthwith deliver the same to
the Senior Creditor in precisely the form received (except for the endorsement or assignment of such Junior Creditor where necessary) for application to the Senior Creditor Obligations then due and owing (whether by virtue of maturity or any
installment or acceleration or otherwise), and until so delivered the same shall be held in trust by such Junior Creditor as the property of the Senior Creditor. All collateral securing the Senior Creditor Obligations and all proceeds in respect
thereof received by the Senior Creditor after such time as the Senior Creditor Obligations (other than indemnity and other contingent obligations) shall have been fully paid and satisfied and all commitments to make loans or otherwise make advances
or other extensions of credit under the Credit Agreement have been terminated, shall be forthwith paid over, in the funds and currency received, to the Junior Creditors for application to the Junior Creditor Obligations (unless otherwise required by
law). 
 8. Each Junior Creditor hereby represents, warrants and covenants to the Senior Creditor that such Junior Creditor has not
heretofore and will not in the future subordinate in favor of any other person any right, claim or interest in any part of the Junior Creditor 

  
 - 5 - 

 
Obligations or commence or join with any other creditor in commencing any bankruptcy, reorganization or insolvency proceeding against any Loan Party; provided that the forgoing shall not prohibit
any action permitted under the final sentence of Section 6 hereof. In addition, each Junior Creditor hereby represents, warrants and covenants to the Senior Creditor (for itself and the benefit of the Lenders) that the Junior Creditor
Obligations are unsecured and the Junior Creditors shall not take any action to have the Junior Creditor Obligations become secured until the Senior Creditor Obligations shall have been fully paid and satisfied and all commitments to make loans or
otherwise make advances or other extensions of credit under the Credit Agreement have been terminated; provided, however, notwithstanding the foregoing, the Junior Creditors may reduce the Junior Creditor Obligations in their sole discretion;
provided further, however, no Junior Creditor shall be permitted to take any action to enforce any lien or otherwise attach any lien, in each case, resulting from any such judgment, until the Senior Creditor Obligations shall have been fully paid
and satisfied and all commitments to make loans or otherwise make advances or other extensions of credit under the Credit Agreement have been terminated, unless the Junior Creditor Obligations giving rise to such lien were permitted to be paid under
the terms and provisions of Section 3 hereof. 
 9. Each Junior Creditor agrees that it may not at any time enter into any agreement
with any Loan Party which materially modifies, changes or waives any terms or conditions of the Junior Creditor Obligations and adversely affects the Senior Creditors including, but not limited to, the Junior Creditor Notes and/or any of the other
Junior Creditor Documents, while any of the Senior Creditor Obligations (other than indemnity and other contingent obligations) remain unpaid, without the prior written consent of the Senior Creditor (such consent to not be unreasonably withheld or
delayed). 
 10. Subject to Section 3 hereof, the Senior Creditor and the Lenders, at any time and from time to time, may enter into
such agreement or agreements with any Loan Party as the Senior Creditor may deem proper extending the time of payment, increasing the amount of the Senior Creditor Obligations, increasing the interest rate accruing with respect to the Senior
Creditor Obligations or otherwise altering the terms of the Credit Agreement or any Other Documents affecting any security or guarantee conveyed in connection therewith, or may exchange, sell or surrender or otherwise deal with such security,
without notice to or the consent of the Junior Creditors and without in any way impairing or affecting the rights granted to the Senior Creditor and the Lenders pursuant to this Subordination Agreement. 

11. Each Junior Creditor agrees that (i) subject to Section 3 hereof, the provisions hereof shall inure to the benefit of any
financial institution obtained by the Loan Parties or the Senior Creditor to provide replacement working capital or other financing for the Loan Parties in place of the Senior Creditor and the Lenders, regardless of whether any such replacement
lender provides its own financing or succeeds the Senior Creditor’s financing by assignment, and if requested by such replacement lender, each Junior Creditor shall execute with such replacement lender a subordination agreement substantially
similar to and substantively consistent with (and no more onerous with respect to the Junior Creditors than) this Subordination Agreement; (ii) as a prior condition of any assignment of any of its interests under any of the Junior Creditor
Documents, each Junior Creditor shall require the assignee to acknowledge this Subordination Agreement and agree, in writing, to be bound by the terms and conditions hereof; and (iii) the Junior Creditor Notes shall bear a legend which refers
to this Subordination Agreement and states that the applicable Junior Creditor’s rights to payment thereunder are subject to the terms hereof. 

  
 - 6 - 

 12. Each Junior Creditor (on a several and not joint basis) agrees to indemnify and to hold the
Senior Creditor and the Lenders, and each of their respective officers, directors, agents and employees (each, an “Indemnified Party”) harmless for any and all direct losses, damages, liabilities, expenses and obligations, including
reasonable and documented attorneys’ fees and expenses, arising as a result of any actions of such Junior Creditor taken contrary to this Subordination Agreement; provided, however, that the foregoing indemnity (x) shall not:
(i) exceed an amount equal to the maximum amount recoverable under or with respect to the Junior Creditor Obligations; and/or (ii) apply to claims, damages, losses, liabilities, expenses and obligations solely attributable to an
Indemnified Party’s gross negligence, bad faith or willful misconduct or arising out of or in connection with any claim, litigation, investigation or proceeding that does not involve an act or omission of such Junior Creditor and that is
brought by an Indemnified Person against any other Indemnified Person and (y) in the case of attorneys’ fees and expenses, shall be limited to one primary counsel for all Indemnified Parties and one local counsel, in each relevant
jurisdiction, for all Indemnified Parties and one or more additional counsel if one or more conflicts of interest arise and shall exclude allocated costs of in-house counsel. The indemnity contained in this Section shall survive the termination of
this Subordination Agreement, payment of any Senior Creditor Obligations and assignment of any rights hereunder but in each case, only with respect to any applicable indemnification obligations arising as a result of actions of any Junior Creditor
taken contrary to this Subordination Agreement prior to such termination, payment or assignment, as the case may be. If any action or claim shall be brought or threatened against any Indemnified Party by reason of or in connection with one of the
foregoing events, the Senior Creditor, the Lenders or such Indemnified Party shall promptly notify the Junior Creditors in writing. Each Junior Creditor may participate at its expense in the defense of any such action or claim, including the
employment of counsel and the payment of all costs of litigation associated with its participation. Notwithstanding the preceding sentence, such Indemnified Party shall have the right to employ its own counsel and to determine its own defense of
such action in any such case, but the reasonable and documented fees and expenses of such counsel for such Indemnified Party shall be at the expense of the Junior Creditors. In the event that any Junior Creditor assumes the defense of such
proceedings and employs counsel in connection therewith, such Junior Creditor shall keep such Indemnified Party, the Senior Creditor, the Lenders and their respective counsels currently informed of all material developments in such proceeding,

enforced in accordance with, the laws of the State of New York, without regard to the principles of the conflicts of laws thereof.

returned upon the insolvency, bankruptcy or reorganization of Maker or otherwise, Maker’s obligation to make such payment shall be reinstated as though such payment had not been made.

 6.7 No Litigation. No action, suit, litigation, investigation or proceeding of, or before,
any arbitrator or Governmental Authority is pending or, to the knowledge of Maker, threatened by or against Maker or any of its property or assets (a) with respect to the Note or any of the transactions contemplated hereby or (b) that

 8.2 For purposes of this Section 8, “Senior
Indebtedness” shall mean the principal of, premium, if any, and interest (including any interest accruing after the filing of a petition in bankruptcy) on and other amounts due on or in connection with any indebtedness of the Company as

Senior Indebtedness described in the Subordination Agreement is replaced by other Senior Indebtedness (including replacement Senior Indebtedness in amounts greater than the Senior Indebtedness described in the Subordination Agreement). In the event
Maker proposes to issue any future Senior Indebtedness, Noteholder, and each subsequent assignee of any interest in the Note, agrees to execute any subordination agreements as required by Maker provided that such subordination agreements shall be

 8 

 8.5 Notwithstanding the provisions of the Subordination Agreement, so long as and to the extent
that (i) no Default (as defined in the Credit Facility) or Event of Default (as defined in the Credit Facility) under the Credit Facility has occurred or will occur as a result thereof, Maker may make interest payments in full or in part to the

Facility) under the Credit Facility has occurred or will occur as a result thereof and the Loan Parties (as defined in the Credit Facility) have demonstrated, in form and substance reasonably satisfactory to the Senior Creditor (as defined in the
Credit Facility), compliance with the financial covenant contained in Section 8.6, Maker may pay all or any part of outstanding and unpaid principal amount and interest (including, without limitation, the Make Whole Amount where

right, power or remedy referred to herein or now or hereafter available at law, in equity, by statute or otherwise. Maker shall pay all fees (including attorneys’ fees), expenses and court costs incurred by Holders for any claim or controversy

capitalized terms used herein shall have the meanings ascribed to them in the Credit Agreement. 

  
 - 2 - 

 2. Except as otherwise set forth in Section 3 hereof and the final sentence of
Section 6 hereof, no Junior Creditor will ask, demand, sue for, take or receive from any Loan Party, in any manner, without the consent of the Senior Creditor the whole or any part of any monies, now or hereafter owing by such Loan Party to

 - 3 - 

 
or right on behalf of any third party. The sending or receipt of such notice shall not obligate the recipient to cure such default. The Loan Parties hereby consent and agree to the Senior

to the provisions of Sections 2 and 3 hereof, all rights to payment and Liens, if any, of any of the Junior Creditors with respect to the Junior Creditor Obligations, whether now existing or hereafter arising and howsoever existing, in any assets of

Senior Creditor Obligations (other than indemnity and other contingent obligations) shall first be paid in full, or payment thereof provided for in money or monies worth in accordance with the terms thereof, before any payment is made on account of
any Junior Creditor Obligations; and upon any such distribution, division or application, any payment or distribution of any kind or character, either in cash, securities or other property, which shall be payable or deliverable upon or with respect
to the Junior Creditor Obligations shall be paid or delivered directly to the Senior Creditor for application to the Senior Creditor Obligations until the Senior Creditor Obligations (other than indemnity and other contingent obligations) shall have
been fully paid and satisfied and all commitments to make loans or otherwise make advances or other extensions of credit under the Credit Agreement have been terminated. Notwithstanding anything to the contrary contained in Section 2, this
Section 5, Section 7 or otherwise in this Subordination Agreement, the Junior Creditors shall be entitled to receive and retain any distribution of Reorganization Subordinated Securities. For purposes of this Subordination Agreement,
“Reorganization Subordinated Securities” shall mean any (i) debt securities issued in substitution of or exchange for all or any portion of the Junior Creditor Obligations that are subordinated in right of payment, performance and
otherwise to the Senior Creditor Obligations to at least the same extent that the Junior Creditor Obligations are subordinated to the Senior Creditor Obligations pursuant to and in accordance with the terms and provisions of this Subordination
Agreement, and/or (ii) equity securities issued in substitution of or exchange for all or any portion of the Junior Creditor Obligations, provided, that if such equity securities provide for mandatory redemption or mandatory dividend or
distribution payments, the making and payment thereof shall be subordinated in right of payment, performance and 

  
 - 4 - 

 
otherwise to the Senior Creditor Obligations (or any equity securities issued in substitution of or exchange for all or any portion of the Senior Creditor Obligations) to at least the same extent
that the Junior Creditor Obligations are subordinated to the Senior Creditor Obligations pursuant to and in accordance with the terms and provisions of this Subordination Agreement. 

6. In the event of any bankruptcy, reorganization or insolvency proceeding, each Junior Creditor hereby irrevocably appoints the Senior
Creditor as its attorney-in-fact with full power to act in the place and stead of such Junior Creditor, in all matters relating to or affecting the Junior Creditor Obligations, for the purpose of protecting or preserving the Senior Creditor’s
rights under this Subordination Agreement, including for that purpose, the right to execute, verify, deliver and, upon the failure of such Junior Creditor to do so promptly, but in any event, prior to ten (10) days before the expiration of the
time to make, present, file and/or vote any such proof of claim, as applicable, to make, present, file and/or vote such proofs of claim, as applicable, against any Loan Party on account of all or any part of the Junior Creditor Obligations, as the
Senior Creditor may deem advisable and to receive and collect any and all distributions under any federal or state debtor relief statute on account of the Junior Creditor Obligations and to apply the same on account of the Senior Creditor
Obligations. Senior Creditor shall promptly provide the Junior Creditors with notice of any exercise by the Senior Creditor of the aforementioned power of attorney; provided, however, the failure to provide such notice shall not affect the
validity of any such action, or create a cause of action against the party failing to give such notice, or create any claim or right on behalf of any third party. Subject to the foregoing limitations, the Junior Creditors shall retain the right to
file, vote and otherwise act in any applicable bankruptcy proceeding in their capacity as such; provided, however, each Junior Creditor hereby acknowledges and agrees that it shall not file, vote or otherwise act as a creditor in a bankruptcy
proceeding in any manner that contravenes the terms and provisions of this Subordination Agreement. 
 7. Except as otherwise set forth in
Section 3 hereof and except as permitted in Section 5 hereof with respect to Reorganization Subordinated Securities, should any payment or distribution upon or with respect to the Junior Creditor Obligations or any security therefor or
proceeds thereof be received by any of the Junior Creditors prior to the satisfaction of all of the Senior Creditor Obligations (other than indemnity and other contingent obligations), each such Junior Creditor shall forthwith deliver the same to
the Senior Creditor in precisely the form received (except for the endorsement or assignment of such Junior Creditor where necessary) for application to the Senior Creditor Obligations then due and owing (whether by virtue of maturity or any
installment or acceleration or otherwise), and until so delivered the same shall be held in trust by such Junior Creditor as the property of the Senior Creditor. All collateral securing the Senior Creditor Obligations and all proceeds in respect
thereof received by the Senior Creditor after such time as the Senior Creditor Obligations (other than indemnity and other contingent obligations) shall have been fully paid and satisfied and all commitments to make loans or otherwise make advances
or other extensions of credit under the Credit Agreement have been terminated, shall be forthwith paid over, in the funds and currency received, to the Junior Creditors for application to the Junior Creditor Obligations (unless otherwise required by
law). 
 8. Each Junior Creditor hereby represents, warrants and covenants to the Senior Creditor that such Junior Creditor has not
heretofore and will not in the future subordinate in favor of any other person any right, claim or interest in any part of the Junior Creditor 

  
 - 5 - 

 
Obligations or commence or join with any other creditor in commencing any bankruptcy, reorganization or insolvency proceeding against any Loan Party; provided that the forgoing shall not prohibit
any action permitted under the final sentence of Section 6 hereof. In addition, each Junior Creditor hereby represents, warrants and covenants to the Senior Creditor (for itself and the benefit of the Lenders) that the Junior Creditor
Obligations are unsecured and the Junior Creditors shall not take any action to have the Junior Creditor Obligations become secured until the Senior Creditor Obligations shall have been fully paid and satisfied and all commitments to make loans or
otherwise make advances or other extensions of credit under the Credit Agreement have been terminated; provided, however, notwithstanding the foregoing, the Junior Creditors may reduce the Junior Creditor Obligations in their sole discretion;
provided further, however, no Junior Creditor shall be permitted to take any action to enforce any lien or otherwise attach any lien, in each case, resulting from any such judgment, until the Senior Creditor Obligations shall have been fully paid
and satisfied and all commitments to make loans or otherwise make advances or other extensions of credit under the Credit Agreement have been terminated, unless the Junior Creditor Obligations giving rise to such lien were permitted to be paid under
the terms and provisions of Section 3 hereof. 
 9. Each Junior Creditor agrees that it may not at any time enter into any agreement
with any Loan Party which materially modifies, changes or waives any terms or conditions of the Junior Creditor Obligations and adversely affects the Senior Creditors including, but not limited to, the Junior Creditor Notes and/or any of the other
Junior Creditor Documents, while any of the Senior Creditor Obligations (other than indemnity and other contingent obligations) remain unpaid, without the prior written consent of the Senior Creditor (such consent to not be unreasonably withheld or
delayed). 
 10. Subject to Section 3 hereof, the Senior Creditor and the Lenders, at any time and from time to time, may enter into
such agreement or agreements with any Loan Party as the Senior Creditor may deem proper extending the time of payment, increasing the amount of the Senior Creditor Obligations, increasing the interest rate accruing with respect to the Senior
Creditor Obligations or otherwise altering the terms of the Credit Agreement or any Other Documents affecting any security or guarantee conveyed in connection therewith, or may exchange, sell or surrender or otherwise deal with such security,
without notice to or the consent of the Junior Creditors and without in any way impairing or affecting the rights granted to the Senior Creditor and the Lenders pursuant to this Subordination Agreement. 

11. Each Junior Creditor agrees that (i) subject to Section 3 hereof, the provisions hereof shall inure to the benefit of any
financial institution obtained by the Loan Parties or the Senior Creditor to provide replacement working capital or other financing for the Loan Parties in place of the Senior Creditor and the Lenders, regardless of whether any such replacement
lender provides its own financing or succeeds the Senior Creditor’s financing by assignment, and if requested by such replacement lender, each Junior Creditor shall execute with such replacement lender a subordination agreement substantially
similar to and substantively consistent with (and no more onerous with respect to the Junior Creditors than) this Subordination Agreement; (ii) as a prior condition of any assignment of any of its interests under any of the Junior Creditor
Documents, each Junior Creditor shall require the assignee to acknowledge this Subordination Agreement and agree, in writing, to be bound by the terms and conditions hereof; and (iii) the Junior Creditor Notes shall bear a legend which refers
to this Subordination Agreement and states that the applicable Junior Creditor’s rights to payment thereunder are subject to the terms hereof. 

  
 - 6 - 

 12. Each Junior Creditor (on a several and not joint basis) agrees to indemnify and to hold the
Senior Creditor and the Lenders, and each of their respective officers, directors, agents and employees (each, an “Indemnified Party”) harmless for any and all direct losses, damages, liabilities, expenses and obligations, including
reasonable and documented attorneys’ fees and expenses, arising as a result of any actions of such Junior Creditor taken contrary to this Subordination Agreement; provided, however, that the foregoing indemnity (x) shall not:
(i) exceed an amount equal to the maximum amount recoverable under or with respect to the Junior Creditor Obligations; and/or (ii) apply to claims, damages, losses, liabilities, expenses and obligations solely attributable to an
Indemnified Party’s gross negligence, bad faith or willful misconduct or arising out of or in connection with any claim, litigation, investigation or proceeding that does not involve an act or omission of such Junior Creditor and that is
brought by an Indemnified Person against any other Indemnified Person and (y) in the case of attorneys’ fees and expenses, shall be limited to one primary counsel for all Indemnified Parties and one local counsel, in each relevant
jurisdiction, for all Indemnified Parties and one or more additional counsel if one or more conflicts of interest arise and shall exclude allocated costs of in-house counsel. The indemnity contained in this Section shall survive the termination of
this Subordination Agreement, payment of any Senior Creditor Obligations and assignment of any rights hereunder but in each case, only with respect to any applicable indemnification obligations arising as a result of actions of any Junior Creditor
taken contrary to this Subordination Agreement prior to such termination, payment or assignment, as the case may be. If any action or claim shall be brought or threatened against any Indemnified Party by reason of or in connection with one of the
foregoing events, the Senior Creditor, the Lenders or such Indemnified Party shall promptly notify the Junior Creditors in writing. Each Junior Creditor may participate at its expense in the defense of any such action or claim, including the
employment of counsel and the payment of all costs of litigation associated with its participation. Notwithstanding the preceding sentence, such Indemnified Party shall have the right to employ its own counsel and to determine its own defense of
such action in any such case, but the reasonable and documented fees and expenses of such counsel for such Indemnified Party shall be at the expense of the Junior Creditors. In the event that any Junior Creditor assumes the defense of such
proceedings and employs counsel in connection therewith, such Junior Creditor shall keep such Indemnified Party, the Senior Creditor, the Lenders and their respective counsels currently informed of all material developments in such proceeding,
including the provision of all documents reasonably requested by such Indemnified Party, the Senior Creditor, the Lenders or their respective counsels. Neither such Indemnified Party, the Senior Creditor nor any of the Lenders shall be liable for
any settlement of such action effected without the prior written consent of such Indemnified Party, the Senior Creditor, the Lenders and their respective counsels. No Junior Creditor shall be liable for any settlement of any such action effected
without its consent. In no event, shall any Junior Creditor be liable on any theory of liability for any special, indirect, consequential or punitive damages (including without limitation, any loss of profits, business or anticipated savings);
provided that nothing contained in this sentence shall limit any Junior Creditor’s indemnification and reimbursement obligations to the extent set forth herein in connection with any claim by a third party with respect to which an Indemnified
Party is entitled to indemnification hereunder. 

  
 - 7 - 

 13. No waiver shall be deemed to be made by the Senior Creditor or the Lenders of any of their
rights hereunder unless the same shall be in writing, signed by the Senior Creditor or the Lenders, and such waiver, if any, shall be a waiver only with respect to the specific matter or matters to which the waiver relates and shall in no way impair
the rights of the Senior Creditor or the Lenders or the obligations of the Junior Creditors to the Senior Creditor or the Lenders in any other respect at any other time. 

14. This Subordination Agreement shall be binding upon and inure to the benefit of the Junior Creditors, the Senior Creditor, the Lenders and
their respective successors and assigns. This Subordination Agreement may be executed by facsimile, e-mail or other electronic communication and in one or more counterparts, each of which shall be deemed to be an original but all of which together
shall constitute one and the same Subordination Agreement. 
 15. This Subordination Agreement shall be governed by, and construed and
enforced in accordance with, the laws of the State of New York, without regard to the principles of the conflicts of laws thereof. 
 16.
Waiver of Jury Trial. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY RELATING TO THIS SUBORDINATION
AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY, WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY. 
 17. The purpose of this
Subordination Agreement is solely to define the relative rights of the Senior Creditor, the Lenders and the Junior Creditors. This Agreement is not intended to and shall not impair, as between the Junior Creditors and Ampco-Pitt Corp. and the other
Loan Parties, the obligation of Ampco-Pitt Corp. and the other applicable Loan Parties to pay the Junior Creditor Obligations as and when the same shall become due and payable in accordance with the terms applicable thereto; provided,
however, the Junior Creditors and the Loan Parties each hereby acknowledge and agree that, notwithstanding the obligation of Ampco-Pitt Corp. and the other applicable Loan Parties to pay the Junior Creditor Obligations as and when the same
shall become due and payable in accordance with the terms applicable thereto, the right of: (i) Ampco-Pitt Corp. and the other applicable Loan Parties to pay; and (ii) the Junior Creditors to receive and retain payment of, such Junior
Creditor Obligations, shall each be subject to the terms and provisions of this Agreement.
