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.

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.

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.

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.

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.

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

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.

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.

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.
