	 	Re:	 Credit Facility provided to MSA Safety Incorporated 

Dear Ladies and Gentlemen: 

Reference is made to that certain Fourth Amended and Restated Credit Agreement, dated as of May 24, 2021, by and among
MSA Safety Incorporated (the “Company” or “you”), the other Borrowers (as defined therein) party thereto, the Guarantors (as defined therein) party thereto, the Lenders (as defined therein) party thereto and PNC
Bank, National Association, as administrative agent (in such capacity, the “Administrative Agent”) (as previously or as hereinafter may be further amended, modified, supplemented or restated from time to time, the “Credit
Agreement”). Capitalized terms used herein and not otherwise defined shall have the meanings assigned to them in the Credit Agreement. 

1.     Overview of Projects 

You have advised us that the Company is contemplating two projects, each of which is more particularly described as set forth
below. 
 (a)    Project Leo 

(i)    General Description. Project Leo contemplates the ultimate transfer to a newly-formed
subsidiary of MSAW of the operating assets and specified liabilities of MSACL through a statutory division and subsequent merger; after giving effect to such statutory division, MSACL, as a surviving entity thereunder, will retain cash, marketable
securities, certain insurance rights applicable to its retained liabilities, certain deferred tax assets, and all of its liabilities relating to asbestos, silica, coal dust, and PFAS and foam-related claims. Immediately prior to the effectiveness of
the division, MSAW will make a cash capital contribution in the amount of $41.3 million to MSACL (the “FMV Contribution”), which amount represents the net fair market value (the “FMV”) of the operating assets
and specified liabilities to be transferred. The FMV was determined by MSAW based on a valuation performed by Kroll Worldwide (formerly Duff & Phelps) (“Kroll”), as evidenced by a fairness opinion dated December 28,
2022 delivered by Kroll to the Board of Managers of MSACL (the “Fairness Opinion”). The ultimate transferee of the operating assets and specified liabilities of MSACL will be MSA Safety Jacksonville Manufacturing, LLC, a newly
formed Pennsylvania limited liability company (“MSAJ”). The foregoing project and the transactions contemplated thereunder, are hereinafter generally referred to as “Project Leo”. 

(ii)    Detailed Description. A more detailed description of Project Leo and the transactions to be
consummated thereunder is as follows: 
  

	 	(1)	 MSACL will enter into that certain Plan of Division, dated on or around the date hereof, in the form
delivered to the Lenders on or prior to the date 

	 	 
hereof (the “Plan of Division”) providing for the division of MSACL into two Pennsylvania limited liability companies: MSACL and a new limited liability company created through
the Plan of Division to be known as MSA SJM, LLC (“MSA SJM”). Under the Plan of Division, MSACL as the surviving entity will retain the Surviving Company Assets and the Surviving Company Liabilities (as each such term is defined in
the Plan of Division), and MSA SJM will be allocated all of the MSA SJM Assets and MSA SJM Liabilities (as each such term is defined in the Plan of Division). 

 

	 	(2)	 Prior to the effectiveness of the Division (such term, and the use of such term hereinafter in this letter
agreement, in each case has the meaning assigned to such term in the Plan of Division), MSAW will make the FMV Contribution to MSACL. The amount of the FMV Contribution represents the net fair market value of the MSA SJM Assets less the MSA SJM
Liabilities, consistent with the Fairness Opinion. The FMV Contribution will be funded by a borrowing under the Credit Agreement. 

  

	 	(3)	 After the effectiveness of the Division: 

 

	 	(i)	 MSA SJM will merge into MSAJ, with MSAJ as the surviving entity (the “Merger”), pursuant to
an Agreement and Plan of Merger (the “Merger Agreement”); and 

  

	 	(ii)	 MSAW will make an additional cash capital contribution to MSACL in an amount not to exceed
$173 million, in order to achieve the desired level of capitalization of MSACL for the Equity Sale (as defined below) (the “Capitalization Contribution”). The Capitalization Contribution will be funded by a borrowing under the
Credit Agreement in accordance with the terms and conditions thereof. 

  

	 	(4)	 Upon the effectiveness of the Division and the Merger, MSAJ will employ the employees currently employed by
MSACL. 

 (b)    Project Horizon 

(i)    General Description. Project Horizon contemplates, on the second (2nd) Business Day after the completion of the Division and other transactions contemplated by Project Leo, the sale by MSAW to an unrelated third party of its entire equity interest in MSACL (the
“Equity Sale”) pursuant to the Purchase Agreement (as defined below) and the related Transaction Documents (as such term is defined in the Purchase Agreement; the Purchase Agreement and such Transactions Documents are collectively,
the “Equity Sale Documents”). Immediately prior to the closing of the Equity Sale, MSACL’s assets and liabilities will consist of the Surviving Company Assets and the Surviving Company Liabilities (as each such term is defined
in the Plan of Division). The foregoing project and the transactions contemplated thereunder, are hereinafter generally referred to as “Project Horizon”; Project Horizon and Project Leo are hereinafter collectively referred to as
the “Transactions”. 

  
 -2- 

 (ii)    Detailed Description. A more detailed
description of Project Horizon and the transactions to be consummated thereunder is as follows: 
  

	 	(1)	 On the second (2nd) Business Day following the
effectiveness of the Division: 

  

	 	(i)	 MSAW will pay in full the outstanding principal amount and accrued interest owed to MSACL on the MSACL
Promissory Notes in an amount not to exceed $112 million (the “Subordinated Debt Payment”). The Subordinated Debt Payment will be funded by a borrowing under the Credit Agreement in accordance with the terms and
conditions thereof. 

  

	 	(ii)	 MSAW, MSACL, Sag Main Holdings, LLC (“Buyer”) and MSAJ (solely in the case of MSAJ, with
respect to the indemnity provisions set forth in the Purchase Agreement) will (a) enter into a Membership Interest Purchase Agreement, substantially in the form delivered to the Lenders on or prior to the date hereof (the “Purchase
Agreement”), and the other Equity Sale Documents, and (b) close the Equity Sale. 

  

	 	(2)	 Immediately following the closing of the Equity Sale, the Company, the existing Domestic Guarantors and MSAJ
(as a guarantor) will enter into a new unsecured term loan facility to be arranged by PNC, and provided by PNC and certain other financial institutions (with PNC acting as administrative agent thereunder), in an aggregate principal amount not to
exceed $250 million (the “New Term Loan Facility”). The New Term Loan Facility will provide for a single delayed draw term loan. The proceeds of the draw under the New Term Loan Facility shall substantially be used to repay a
portion of the borrowings to be made under the Credit Agreement referred to under the description of Project Leo and this description of Project Horizon. 

2.     Specific Consents Requested In Connection With Consummation of the Transactions 

You have advised us that a number of specific actions (including, without limitation, certain of the actions described above)
that the Company and its Subsidiaries intend to consummate in connection with Project Leo and Project Horizon (collectively, the “Contemplated Actions”) are expressly prohibited by certain provisions of the terms of the Credit
Agreement (collectively, the “Restrictive Covenants”). Such Restrictive Covenants, and the applicable Contemplated Actions that would contravene such Restrictive Provisions, are more particularly described in Exhibit A
attached hereto. Notwithstanding the existence of the Restrictive Provisions, you have requested that the Administrative Agent and the Lenders hereby consent to the Contemplated Actions. 

  
 -3- 

 The Administrative Agent and the Lenders party hereto hereby consent to the
Contemplated Actions; provided however that such consent is conditioned on (i) there being no continuing Event of Default as of the date of this letter agreement after giving effect to the consent in this letter agreement to the
Contemplated Actions, or after giving effect to the consummation of all of the Contemplated Actions and (ii) the satisfaction of all conditions set forth in Exhibit B attached hereto (collectively, the “Conditions”), in
each case in form and substance reasonably satisfactory to the Administrative Agent, on or prior to January 31, 2023 (such date, which may be extended by the Administrative Agent in its sole discretion, the “Deadline”). If the
Loan Parties do not satisfy all of the Conditions by the Deadline, the consent set forth in this paragraph will automatically be deemed null and void, and any Contemplated Action taken in contravention of any Restrictive Provision will be deemed to
be an Event of Default under the Credit Agreement. 
 3.     Condition Subsequent – Joinder of MSAJ 

Notwithstanding anything to the contrary contained in any provision of the Credit Agreement, each of the parties hereto hereby
agrees that MSAJ shall join the Credit Agreement as a Guarantor pursuant to, and in accordance with, the provisions of Section 10.13 of the Credit Agreement, no later than thirty (30) days after the date upon which all Conditions are
satisfied (such date, which may be extended by the Administrative Agent in its sole discretion for up to an additional thirty (30) days, the “Joinder Deadline”). If the Loan Parties do not satisfy the requirements of this
Section 3 by the Joinder Deadline, such failure will be deemed an Event of Default under the Credit Agreement. The parties hereby acknowledge and agree that MSAJ was formed on October 19, 2022, and that the provisions of this
Section 3 are hereby given retroactive effect as of such date. 
 4.     Deemed Amendments Upon Closing of the
Transactions 
 If the Conditions are all satisfied on or prior to the Deadline, immediately upon the closing and
consummation of the Equity Sale, the parties hereto hereby agree that the applicable Sections of the Credit Agreement set forth on Exhibit C attached hereto shall automatically be deemed to be amended or modified in accordance with the
express provisions of such Exhibit C. 
 5.     Miscellaneous 

(a)    Each of the Company and each other Loan Party hereby represents and warrants to the Administrative
Agent and each Lender, and agrees with the Administrative Agent and the Lenders, that, as of the date hereof after giving effect to this letter, (i) all of the representations and warranties made by the Credit Parties under the Credit Agreement
and any other Loan Document are true and correct as of the date hereof, except to the extent such representation and warranty expressly relates to an earlier date, and (ii) it has no claim or offset against, or defense or counterclaim to, any
obligation or liability under the Credit Agreement or any other Loan Document, and each of the Company and each other Loan Party hereby waives and releases the Administrative Agent and the Lenders and each of their respective directors, officers,
employees, agents, attorneys, representatives, affiliates and subsidiaries, as of the date hereof, from any and all claims, offsets, defenses and counterclaims of which the Company or any other Loan Party is aware as of the date hereof in connection
with the Credit Agreement and the other Loan Documents, such waiver and release being with full knowledge and understanding of the circumstances and effect thereof and after having consulted legal counsel with respect thereto. 

  
 -4- 

 (b)    The consents and agreements contained herein
shall be limited to the specific consents and agreements made herein. Except as set forth herein, the Administrative Agent and the Lenders hereby expressly reserve all rights, remedies, powers and privileges they have or may have under the Credit
Agreement, any of the other Loan Documents, and applicable law or equity. Except as otherwise modified herein, all other terms and conditions of the Credit Agreement and the other Loan Documents continue in full force and effect and are unmodified
by this letter agreement. 
 (c)    Each of the parties hereto acknowledges and agrees that the
Administrative Agent may act as the administrative agent under the New Term Loan Facility notwithstanding any potential or actual conflict of interest presented by the foregoing and each party hereto hereby waives any claim against Administrative
Agent or any of its affiliates based upon any conflict of interest that Administrative Agent may have with regard to acting as Administrative Agent under the Credit Agreement and acting in such other role. 

(d)    This letter agreement may be executed in separate counterparts, each of which shall be deemed an
original, but all of which together shall be deemed to be one and the same agreement. A signed copy of this letter agreement delivered by facsimile, e-mail or other means of electronic transmission shall be
deemed to have the same legal effect as delivery of an original signed copy of this letter agreement. The parties hereto consent to the use of electronic signatures and records in connection with the transactions hereunder.

	B.	 The Company has informed Prudential and the Noteholders that it is contemplating two transactions, each of
which is more particularly described as set forth below: 

  

	 	(a)	 Project Leo 

(i)     General Description. Project Leo contemplates the ultimate transfer to a
newly-formed subsidiary of MSAW of the operating assets and specified liabilities of Mine Safety Appliances Company, LLC, a Pennsylvania limited liability 

  
 1 

 
company (“MSA”), through a statutory division and subsequent merger; after giving effect to such statutory division, MSA, as a surviving entity thereunder, will retain cash,
marketable securities, certain insurance rights applicable to its retained liabilities, certain deferred tax assets, and all of its liabilities relating to asbestos, silica, coal dust, and PFAS and foam-related claims. Immediately prior to the
effectiveness of the division, MSAW will make a cash capital contribution in the amount of $41.3 million to MSA (the “FMV Contribution”), which amount represents the net fair market value (the “FMV”) of the
operating assets and specified liabilities to be transferred. The FMV was determined by MSAW based on a valuation performed by Kroll, LLC (formerly Duff & Phelps) (“Kroll”), as evidenced by a fairness opinion dated
December 28, 2022 delivered by Kroll to the Board of Managers of MSA prior to making the FMV contribution (the “Kroll Fairness Opinion”). Following the Plan of Division and the transactions contemplated by the Merger Agreement,
and in accordance therewith, MSA Safety Jacksonville Manufacturing, LLC, a newly formed Pennsylvania limited liability company (“MSAJ”) and a Wholly-Owned Subsidiary of MSAW, shall be the ultimate transferee of the operating assets
and specified liabilities described as the “MSA SJM Assets” and the “MSA SJM Liabilities” in the Plan of Division (as defined below). The foregoing project and the transactions contemplated thereunder, are hereinafter generally
referred to as “Project Leo”. 
  

	 	(ii)	 Detailed Description. A more detailed description of Project Leo and the transactions to be
consummated thereunder is as follows: 

  

	 	(1)	 MSA has entered into that certain Plan of Division, dated as of December 29, 2022, in the form

liability company created through the Plan of Division to be known as MSA SJM, LLC (“MSA SJM”). Under the Plan of Division: 

  

	 	(i)	 MSA SJM will retain the MSA SJM Assets and MSA SJM Liabilities (each as defined and described in the Plan of
Division). 

  

	 	(ii)	 MSA will retain the Surviving Company Assets and Surviving Company Liabilities (each as defined and
described in the Plan of Division). 

  

	 	(2)	 Prior to the effectiveness of the Division (such term, and the use of such term hereafter, in each case, has
the meaning assigned to such term in the Plan of Division), MSAW will make the FMV Contribution to MSA. The amount of the FMV Contribution represents the net fair market value of the MSA SJM Assets less the MSA SJM Liabilities, consistent with the
Kroll Fairness Opinion. The capital contribution would be funded by a borrowing under the Bank Credit Agreement. 

  
 2 

	 	(3)	 After the effectiveness of the Division: 

 

	 	(i)	 MSA SJM will merge into MSAJ, with MSAJ as the surviving entity (the “Merger”), pursuant to
an Agreement and Plan of Merger entered as of January 3, 2023 (the “Merger Agreement”). 

  

	 	(ii)	 MSAW will make an additional cash capital contribution to MSA in an amount not to exceed $173 million, in
order to achieve the desired level of capitalization of MSA for the Equity Sale (as defined below) (the “Capitalization Contribution”). The Capitalization Contribution would be funded by a borrowing under the Bank Credit Agreement.

  

	 	(4)	 Upon the effectiveness of the Division and the Merger, MSAJ will employ the employees currently employed by
MSA. 

  

	 	(b)	 Project Horizon 

(i)     General Description. Project Horizon contemplates, on the second (2nd) Business Day after the completion of the Division and other transactions contemplated by Project Leo, the sale by MSAW to an unrelated third party of its entire equity interest in MSA (the
“Equity Sale”) pursuant to a Membership Interest Purchase Agreement (as defined below) and the related Transaction Documents (as such term is defined in the Membership Interest Purchase Agreement; the Membership Interest Purchase
Agreement and such Transaction Documents are collectively, the “Equity Sale Documents”). Immediately prior to the closing of the Equity Sale, MSA’s assets and liabilities will consist of the Surviving Company Assets and the
Surviving Company Liabilities. The foregoing project and the transactions contemplated thereunder, are hereinafter generally referred to as “Project Horizon”; Project Horizon and Project Leo are hereinafter collectively referred to
as the “Transactions”. 
  

	 	(ii)	 Detailed Description. A more detailed description of the contemplated Project Horizon transaction is
as follows: 

  

	 	(1)	 On the second (2nd) Business Day following the
effectiveness of the Division: 

  

	 	(i)	 MSAW will pay in full the outstanding principal amount and accrued interest owed to MSA on the MSACL
Promissory Notes in an amount not to exceed $112 million (the “Subordinated Debt Payment”). The Subordinated Debt Payment will be funded by a borrowing under the Bank Credit Agreement. 

  
 3 

	 	(ii)	 MSAW, MSA, Sag Main Holdings, LLC (“MSACL Buyer”) and MSAJ (solely in the case of MSAJ,

without limitation, certain of the actions described above) that the Company and its Subsidiaries intend to consummate in connection with Project Leo and Project Horizon (collectively, the “Contemplated Actions”) are expressly
