 PREAMBLE 
 Mine Safety Appliances Company (the “Company”) hereby establishes this Supplemental Executive Retirement Plan (the “Plan”) effective January 1, 2008 as provided below. 
 WHEREAS, the Company had previously established an executive benefit plan known as the “Executive Insurance Program” (the “EIP”)
which provided both pre-retirement life insurance and post-retirement income benefits to eligible members of the Company’s senior management; and 
 WHEREAS, when Congress enacted the American Jobs Creation Act of 2004, that Act contained a new section of the Internal Revenue Code, Section 409A, which imposed a new set of rules on plans or programs which
provided deferred compensation to employees. 
 WHEREAS, the payment of post-retirement income benefits is treated as deferred compensation
under Code Section 409A, and subjected the EIP to the new rules; and 
 WHEREAS, the Company accordingly decided to terminate the EIP
and to replace it with the Plan; and 
 WHEREAS, the Plan is an unfunded plan of deferred compensation subject to Internal Revenue Code
Section 409A, is subject to FICA taxes in accordance with the non-account balance provisions of Internal Revenue Code Section 3121, and is an unfunded, nonqualified plan of deferred compensation for a select group of management or highly
compensated employees for purposes of Title I of the Employee Retirement Income Security Act of 1974, as amended. 
 NOW THEREFORE, the Plan
is hereby established as follows:

 - 6 - 

 ARTICLE II 
 SERP BENEFIT 
 2.1 Eligibility for a SERP Benefit. A Vested Participant shall become eligible
to receive a SERP Benefit as of the date of his Retirement. 
 2.2 Amount of the SERP Benefit. The aggregate amount of the SERP
Benefit a Vested Participant shall be entitled to receive shall be based upon the Vested Participant’s title at the time of the Vested Participant’s Retirement according to the attached Appendix A or Appendix B whichever is applicable.
However, the Compensation Committee of the Board shall have the authority to increase the amount of a Participant’s SERP Benefit at their sole discretion. 
 2.3 Form of Payment. The actual payment of the SERP Benefit shall be in the form of a series of approximately equal periodic payments over a period of fifteen (15) years. Each such payment to be equal to
the quotient of the aggregate SERP Benefit divided by the number of payments to be made. No interest shall accrue on any unpaid benefit amounts. 
 2.4 Commencement of the SERP Benefit. Following a Vested Participant’s Retirement, the
Vested Participant shall commence to receive the SERP Benefit on the first day of the seventh (7th) month following the month in which the
Vested Participant’s Retirement occurs. The first payment shall be equal to the sum of seven (7) monthly payments (the six payments delayed plus the payment due at the beginning of the seventh (7th) month) and shall include interest on the delayed payments calculated at the prime rate specified in the Northeast Edition of the Wall Street Journal on the first day of the
delay period. All payments shall be payable as soon as administratively feasible on or after the first day of each successive month, but in no event later than the second pay processed thereafter pursuant to the Company’s routine payroll
practices as in effect from time to time. 
 2.5 Effect of a “Change in Control”. Notwithstanding any other provision of
this Plan, if a Vested Participant incurs a Separation from Service on or within the two (2)-year period immediately following a Change in Control, the Company shall pay to the Vested 

  

 - 7 - 

 
Participant a lump sum amount equal to the aggregate SERP amount described in Section 2.2. Such payment shall be made as soon as administratively
feasible on or after the first day of the seventh (7th) month following the month of the Vested Participant’s Separation from Service, but
in no event later than the second pay processed thereafter pursuant to the Company’s routine payroll practices as in effect from time to time. 
 2.6 Death Benefits. 
 (a) Before Retirement. If a Vested Participant has a Separation from Service due to death prior
to Retirement, a death benefit equal to the aggregate SERP amount shall be paid to the Participant’s surviving spouse, if living, in a series of approximately equal periodic payments over a period of fifteen (15) years. If the
Participant is not vested, or if the Participant is not married, no death benefits will be paid. 
 (b) After Retirement. If a
Participant dies after Retirement, the Participant’s Beneficiary shall receive the remaining payments of the SERP Benefit that would have been payable to the Participant if he had survived, except that the 6-month delay set forth in
Section 2.4 shall not apply and the form of payment shall be a continuation of the monthly payments described in of Section 2.3. If there is no designated Beneficiary, or if the named Beneficiary predeceased the Participant, the remaining
unpaid balance of the SERP Benefit shall be paid to the Participant’s estate. If the Beneficiary dies before all remaining SERP Benefits have been paid, the remaining unpaid balance of the SERP Benefit shall be paid to the Beneficiary’s
estate. 
 (c) After a Change in Control. If a Participant becomes entitled to a SERP Benefit described in Section 2.5, but dies
before the initial payment date, the Company shall pay to the Vested Participant’s surviving spouse, if living, a lump sum amount equal to the aggregate SERP amount described in Section 2.2. Such payment shall be made within thirty
(30) days of the date of the Participant’s death. If there is no surviving spouse and no other Beneficiary has been named, the lump sum shall be paid to the Participant’s estate. 
  

 - 8 - 

 (d) Beneficiary Designation. Each Participant shall have the right to designate and from time to
time change the designation of a Beneficiary to receive any benefits which may be payable hereunder in the event of the death of the Participant. 
 2.7 Effect of Reemployment. In the event that a Participant has retired, has commenced the receipt of SERP Benefits under this Article II and is subsequently reemployed by the Company, the payment of the SERP Benefits shall cease
during the Participant’s period of reemployment. Upon the occurrence of a subsequent Retirement, the SERP Benefits shall resume at the same level with the remaining balance paid over the remainder of the fifteen (15) year payment period.
However, if the Participant is in a higher position at the time of the subsequent Retirement, the amount of SERP Benefit the Participant is entitled to on the subsequent Retirement shall be calculated using the higher benefit amount listed in the
Table of Benefit Amounts, reduced for the dollar amount of the SERP Benefits received prior to the Participant’s reemployment. The net balance shall be paid over the remainder of the fifteen (15) year payment period. 
  

 - 9 - 

 ARTICLE III 
 FUNDING AND PARTICIPANT’S INTEREST 
 3.1 Unfunded SERP. The Plan shall be unfunded and no
trust is created by the existence of the Plan. There will be no funding of any SERP Benefit; provided, however, that nothing herein shall prevent the Company from establishing one or more grantor trusts or other dedicated funding sources from which
SERP Benefits may be paid. Notwithstanding the establishment of one or more grantor trusts or other dedicated funding sources from which SERP Benefits may be paid, the right of a Participant to receive SERP Benefits shall constitute an unsecured
contractual obligation by the Company to make benefit payments in the future, and all such benefits shall be deemed to be paid from the general assets of the Company. 
 3.2 Participant’s Interest in Plan. A Participant has an interest only in the contractual right to receive SERP Benefits described in Article II. A Participant has no rights or interests in any specific
funds, stock or securities of the Company by reason of participation in the Plan and entitlement to a SERP Benefit. Nothing in the Plan shall be interpreted as a guaranty that any funds in a grantor trust or the assets of the Company will be
sufficient to pay the SERP Benefit. The right of any Participant or Beneficiary to a SERP Benefit shall be no greater than the right of any unsecured general creditor of the Company. 
  

 - 10 - 

 ARTICLE IV 
 GENERAL PROVISIONS 
 4.1 Administration. 
 (a) Generally. The Plan shall be administered by the Administrator. The Administrator is hereby authorized to delegate any part or
all of its duties to such other administrators as it may appoint. 
 (b) Duties. The Administrator (or its delegate)
shall perform the duties required, and shall have the powers necessary, to administer the Plan and carry out the provisions thereof. 
 (c) Powers. The powers of the Administrator (or its delegate) shall be as follows: 
 (1) To determine any
question arising in connection with the Plan (and its decision or action in respect thereof shall be final, conclusive and binding upon the Company and the Participants and other individual interested herein); 
 (2) To engage the services of counsel or an attorney (who may be counsel or attorney for the Company) and an actuary, if it deems
necessary, and such other agents or assistants as it deems advisable for the proper administration of the Plan; and 
 (3) To
receive from the Company and from Participants such information as shall be necessary for the proper administration of the Plan. 
 (d) Records and Reports. The Administrator shall keep a record of proceedings and actions and shall maintain or cause to be maintained all such books of account, records, and other data as shall be necessary for the proper
administration of the Plan. Such records shall contain all relevant data pertaining to Participants and their rights under this Plan. 

  

 - 11 - 

 
The Administrator shall have the duty to carry into effect all rights or benefits provided under the Plan to the extent assets of the Company are properly
available. 
 (e) Interpretation. The Administrator may reasonably take any action, correct any defect, supply any
omission or reconcile any inconsistency in the Plan, or in any Beneficiary designation under the Plan, in the manner and to the extent it shall deem necessary to carry this Plan into effect or to carry out the Company’s intent and purposes in
adopting the Plan. Any decision, interpretation or other action made or taken in good faith by the Administrator arising out of or in connection with the Plan, shall be within its reasonable discretion, and shall be final, binding and conclusive on
the Company and all Participants and Beneficiaries and their respective heirs, executors, administrators, successors and assigns, except as otherwise provided in this Article IV. The Administrator’s determinations hereunder need not be
uniform or consistent. 
 4.2 Claim and Appeal Procedure. 
 (a) Application for Benefits. In the event of a claim by a Participant or other person for or in respect to any benefit under the
Plan, such Participant or other person (the “Claimant”) shall present the reason for the claim in writing to the Administrator or to such other person or entity designated and communicated by the Administrator. 
 (b) Claims and Appeals. 
 1. In the event a claim for benefits is denied by the Administrator, written notice of the denial will be provided within ninety (90) days after receipt of the claim, or within one hundred and eighty
(180) days if special circumstances require an extension of time (in which event the Claimant will be notified in writing of the delay during the initial ninety (90)-day period and the notice will indicate the special circumstances requiring an
extension of time and the date by which the Administrator expects to render the benefit determination). The notice shall set forth: 
 a. the specific reason(s) for the denial; 
  

 - 12 - 

 b. specific reference to the Plan provisions on which the denial is based; 

c. a description of any additional material or information which must be submitted to perfect the claim, and an explanation of why
such material of information is necessary; 
 d. an explanation of the Plan’s review procedure; and 
 e. the time limits applicable to the Plan’s review procedure and a statement of the claimant’s right to bring a civil action
under Section 502(a) of ERISA following an adverse benefit determination on review. 
 2. The Claimant shall have sixty
(60) days after the day on which such written notice of denial is received, in which to apply (in person or by his authorized representative) to the Administrator in writing for a full and fair review of the denial of his claim. In connection
with such review, the Claimant (or his representative) shall be afforded reasonable opportunity to review pertinent documents, and may submit issues and comments in writing. In addition, the Claimant (or his representative) shall have the right to
submit documents, records, and other information relating to the claim for benefits, and shall be provided, upon request and free of charge, reasonable access to and copies of all documents, records, and other information relevant to the claim for
benefits. At the Committee’s sole option, it may arrange for a written or oral hearing or to meet personally with the Claimant and/or representative for the purpose of hearing the claimant’s contentions and such relevant evidence as the
Claimant may wish to offer. 
 3. The Administrator will issue its decision on review within sixty (60) days after
receipt of the request for review, or within one hundred and twenty (120) days if special circumstances require an extension of time after receipt of the request for review. (Written notice of any such extension will be furnished to the
Claimant before the commencement of such extension, and the notice shall indicate the special circumstances requiring an extension of time and the date by which the Administrator expects to render the determination on review.) The decision will be
in writing and set forth specific reasons for the decision and specific references to pertinent Plan provisions on which the decision is based. In addition, the written notice of the decision denying a claim will contain: 
  

 - 13 - 

 a. a statement that the Claimant is entitled to receive, upon request and free of
charge, reasonable access to and copies of all Plan documents, records, and other information relevant to the claimant’s claim for benefits, and 
 b. a statement of the claimant’s right to bring an action under Section 502(a) of ERISA. 
 4. The Administrator’s review shall take into account all comments, documents, records, and other information submitted by the Claimant (or his representative), without regard to whether such information was submitted or considered in
the initial benefit determination. 
 5. For purposes of this Section 4.2, Plan information is considered
“relevant” to a claimant’s claim if such document, record, or other information 
 a. was relied upon in
making the benefit determination; 
 b. was submitted, considered, or generated in the course of making the benefit
determination, without regard to whether such document, record, or other information was relied upon in making the determination; or 
 c. demonstrates compliance with the Plan’s review procedures and that, if appropriate, the Plan provisions have been applied consistently with respect to similarly situated claimants. 
 (b) Statute of Limitations. Notwithstanding the foregoing, an action brought under ERISA Section 502(a), if any, must be
commenced within one (1) year after the claimant’s receipt of the denial of any appeal pursuant to this Section 4.2(b)(3), without regard to any state or federal statutes establishing provisions relating to limitations of actions.

 (c) Failure to Follow Claims Procedure. If a Claimant does not follow the procedures set forth above, he shall be
deemed to have waived the right to appeal benefit determinations under the Plan. In addition, all determinations by and decisions of the Administrator under this Section 4.2 shall be binding on and conclusive as to the claimant. 
  

 - 14 - 

 4.3 No Contract of Employment. This Plan shall not be construed to establish a guarantee of future
or continued employment by the Company of any Participant. 
 4.4 Non-Alienation. Benefits payable under this Plan shall not be
subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, attachment or garnishment, whether voluntary or involuntary, and any attempt to anticipate, alienate, sell, transfer, assign, pledge, encumber,
attach or garnish the same shall be void; nor shall any such distribution or payment be in any way liable for or subject to the debts, contracts, liabilities, engagements or torts of any person entitled to such distribution or payment. If any
Participant or Beneficiary is adjudicated bankrupt or purports to anticipate, alienate, sell, transfer, assign, pledge, encumber, attach or garnish any such distribution or payment voluntarily or involuntarily, the Administrator, in its discretion,
may hold or cause to be held or applied such distribution or payment or any part thereof to or for the benefit of such Participant or Beneficiary in such manner as the Administrator shall direct. The foregoing provisions of this Section 4.4
shall not apply to the extent provided in a domestic relations court order issued to a spouse or former spouse of a Participant in connection with a divorce if the order is determined by the Administrator to be proper under the Code to transfer tax
liability to such spouse or former spouse and not violative of the terms of applicable law including Code Section 409A. 
 4.5
Payments to Minors or Incompetents. If the Administrator determines that any person entitled to payments under the Plan is a minor or incompetent by reason of physical or mental disability, it may cause all payments thereafter becoming due to
such person to be made to any other person for his benefit, without responsibility to follow the application of amounts so paid. Payments made pursuant to this provision shall completely discharge the Company, the Plan, and the Administrator.

  

 - 15 - 

 4.6 No Effect on Other Compensation and Benefits. Nothing contained herein shall exclude or in any
manner modify or otherwise affect any existing or future rights of any Participant to participate in and receive the benefits of any compensation, bonus, pension, life insurance, medical or other employee benefit plan or program to which he or she
otherwise might be or become entitled as an officer or employee of the Company. 
 4.7 Construction: Choice of Laws. The provisions of
the Plan shall be construed, administered and governed under the laws of the Commonwealth of Pennsylvania (including its statute of limitations provisions, but excluding its choice of law provisions) to the extent such laws are not preempted by
ERISA or any other federal laws which may from time to time be applicable. Whenever any words are used herein in the masculine gender, they shall be construed as though they were also used in the feminine gender in all cases where they would so
apply, and whenever any words are used herein in the singular form, they shall be construed as though they were also used in the plural form in all cases where they would so apply. Titles of Articles and Sections hereof are for convenience
of reference only and are not to be taken into account in construing the provisions of this Plan. 
 4.8 Invalidity of Provisions. If
any provision of the Plan shall be held illegal or invalid for any reason, said illegality or invalidity shall not affect the remaining parts of the Plan, but the Plan shall be construed and enforced as if said illegal and invalid provision had
never been inserted herein. 
 4.9 Status. This Plan is not intended to satisfy the requirements for qualification under Code
Section 401(a). It is intended to be a nonqualified plan that is not subject to ERISA except as required by applicable law. The Plan shall be construed and administered so as to effectuate this intent. 
 4.10 Expenses. The Company shall bear all expenses incurred by the Committee in administering this Plan. 
 4.11 Indemnification for Liability. The Company shall indemnify the Committee and the employees of the Company to whom the Committee delegates
duties under this Plan, against any and all claims, losses, damages, expenses and liabilities arising from their responsibilities in connection with this Plan, unless the same is determined to be due to gross negligence or willful misconduct.

  

 - 16 - 

 4.12 Successors. To the extent not automatically assumed by operation of law, the Company shall
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 Company to expressly assume the Company’s obligations hereunder in the same
manner and to the same extent that the Company would be required to perform if no such succession had taken place. 
 4.13 Withholding
Requirements. Payment of benefits under this Plan shall be subject to applicable withholding requirements. 
 4.14 Amendment and
Termination. The Board shall have the right, at any time, to amend or terminate the Plan in whole or in part; provided, however, that no amendment or termination shall be permissible if it would reduce the amount of the SERP Benefit to which the
Participant would have been entitled if he terminated employment on the effective date of the amendment or termination. The Company, upon review of the effectiveness of the Plan, may at any time recommend amendments to or termination of the Plan to
the Board. The Board reserves the right, in its reasonable discretion, to completely terminate the Plan at any time, provided, however, that termination of the Plan shall not be a distribution event. 
 4.15 Limitation of Liability. Notwithstanding any provision herein to the contrary, the Company, nor any individual acting as employee or agent of
the Company, shall be liable to any Participant, former Participant, Beneficiary, or any other person for any claim, loss, liability or expense incurred in connection with the Plan, unless attributable to fraud or willful misconduct on the part of
the Company or any such agent of the Company, or a breach by the Company of any provision of the Plan that results in a reduction of the SERP Benefit.

fide only if there is a reasonable expectation that the Participant will resume performing services for the Company. In addition, where a leave of absence (a) is due to a medically determinable physical or mental impairment that is expected to
result in death or can be expected to last for a continuous period of at least six months, and (b) such impairment causes the Participant to be unable to perform the duties of his position with the Company or any substantially similar position,
then the Committee shall be permitted to extend the foregoing six (6) month maximum period of leave to not more than twenty-nine (29) months of continuous absence (or such shorter period as is consistent with the Company’s employment
policy regarding termination of employment of employees on disability leave). Whether a Separation from Service has occurred shall be determined by the Committee based on whether the facts and circumstances indicate that the Participant and the
Company reasonably anticipate that no further services would be performed after a certain date. However, if the Participant and the Company reasonably expect that, after such certain date, the Participant would not perform more than twenty percent
(20%) of the average level of bona fide services performed (measured by time devoted to work or other measure of performance deemed appropriate by the Committee) by the Participant over the immediately preceding thirty-six (36) month
period of service to the Company (or any shorter period that represents the Participant’s full period of service to the 

  

 10 

 
Company), then a Separation from Service by the Participant shall be deemed to have occurred as of said certain date for purposes of this Plan. At all times,
this definition shall be construed to comply with the definition of “separation from service” under Section 409(A)(a)(2)(A)(i) of the Code and regulations thereunder. 
 1.27. “Single Life Annuity” means an annuity that provides a monthly payment solely for the life of the Participant (or Spouse, in the

Participant’s Spouse waiving the form of benefit otherwise payable to the Spouse, and acknowledging the effect thereof, where such waiver and acknowledgment are provided in accordance with procedures established and on forms provided by the
Committee and witnessed by a notary public. For purposes of elections under Article IV of the Plan, Spousal Consent shall be required to the same extent that it would be required if such elections were made under the Pension Plan. 
 1.29. “Spouse” means, in accordance with the Federal Defense of Marriage Act, 28 U.S.C.A. §1738C (1996), the person of the
opposite sex, if any, to whom a Participant is legally married under applicable state law. In addition, the term “Spouse” shall include a former spouse who is entitled to a distribution under Section 4.6.

Limitation causes a reduction in the employee’s accrued benefit under the Pension Plan. 
  

 11 

 ARTICLE III 
 AMOUNT OF BENEFITS AND VESTING 
 3.1 Supplemental Pension Benefit. Each Participant (or
his joint annuitant or designated survivor or Beneficiary) shall be entitled under this Plan to receive a Supplemental Pension Benefit in an amount equal to the difference between (a) the benefits (if any) that would have been payable to such
individual under the Pension Plan without regard to the Benefit Limitation, and (b) the benefits (if any) actually payable to such individual under the Pension Plan, in each case determined on the basis of the form of payment specified in
Article IV below and as of the Participant’s Separation from Service; provided, however, that in the case of a Participant who Separated from Service between January 1, 2008 and December 31, 2008, the determination shall be made as of
his Distribution Date. 
 Notwithstanding the foregoing, a Participant who ceases to be an Eligible Employee prior to his Separation from
Service shall forfeit all Supplemental Pension Benefits accrued under the Plan as of that date. 
 3.2 Vesting. A Participant shall be
vested in his Supplemental Pension Benefit only if the Participant would be vested in his benefit under the Pension Plan; provided, however, that such determination shall be made without regard to vesting status that results from a Code
Section 420 transfer under the Pension Plan. 
  

 12 

 ARTICLE IV 
 DISTRIBUTION 
 4.1 Timing of Payment. Payment of the Supplemental Pension Benefit
determined under Article III above shall commence as soon as administratively feasible on or after the Distribution Date, but in no event later than the second pay processed thereafter pursuant to the Company’s routine payroll practices as in
effect from time to time. For purposes of this Section 4.1, the Distribution Date shall be determined as follows: 
 (a)
If the Participant’s Separation from Service is on or after attainment of age fifty-five (55), the Distribution Date is the first day of the calendar month which is seven (7) months after the Participant’s Separation from Service, or

 (b) If the Participant’s Separation from Service is before attainment of age fifty-five (55), the Distribution Date is
the later of the first day of the calendar month after the Participant’s attainment of age fifty-five (55) and the first day of the calendar month which is seven (7) months after the Participant’s Separation from Service.

 Notwithstanding the foregoing, in the case of a Participant whose Distribution Date determined pursuant to
Section 4.1(a) or (b) above, as applicable, would be in 2009 and on or before October 1, 2009, such Participant’s Distribution Date shall be the later of (i) the first day of the calendar month which is seven (7) months
after the Participant’s Separation from Service and (ii) the Participant’s attainment of his Social Security Retirement Age (as defined in the Pension Plan). 
 Effective for Separations from Service occurring on or after January 1, 2009, if the Distribution Date is delayed solely to ensure
that the payment does not begin prior to the first day of the calendar month which is seven (7) months after the Participant’s Separation from Service, the first payment of any applicable Annuity will include payments for all months in the
delay period with interest on the delayed payments calculated at the prime rate specified in the Northeast Edition of the Wall Street Journal on the first day of the delay period. 
 4.2 Forms of Payment. 
 (a) Normal Form. A Participant who is eligible to receive a Supplemental Pension Benefit shall receive such Benefit in the Normal Form unless the Participant has elected to receive payment under an optional form of payment elected by
the Participant under subsection (b) below. 
  

 13 

 (b) Optional Forms. In lieu of the Normal Form, a Participant may elect in
accordance with the provisions of Sections 4.3 and 4.4 below, and subject to any Spousal Consent requirements, to receive the Supplemental Pension Benefit in an Optional Form of Annuity or the Single Life Annuity. 
 4.3 Initial Payment Election. The form of payment of the Supplemental Pension Benefit determined under Section 3.1 above shall be the Normal
Form as provided in Section 4.2(a), unless an optional form of benefit is elected by the Participant, subject to the provisions of Section 4.4. 
 4.4 Subsequent Form of Payment Elections. A Participant may change from one Annuity form of payment to another Annuity form of payment prior to his Distribution Date without restriction (other than any required
Spousal Consent) provided that the Annuity form elected is Actuarially Equivalent to the Annuity option being changed. 
 4.5 Effect of
Change in Control. Notwithstanding any other provision of this Plan, if a Participant is vested in his Supplemental Pension Benefit on the date of the Participant’s Separation from Service and that separation occurs on or within the
two-year period immediately following a Change in Control (other than by the Participant’s death), payment of a Participant’s Supplemental Pension Benefit shall be paid to him in a single cash payment that is Actuarially Equivalent to the
Participant’s Supplemental Pension Benefit, with payment to be made as soon as administratively feasible on or after the first day of the month that is seven (7) months after such Separation from Service, but in no event later than the
second pay processed thereafter pursuant to the Company’s routine payroll practices as in effect from time to time. Payment pursuant to this Section 4.5 shall be in lieu of making payment of such Supplemental Pension Benefit in accordance
with Section 4.1 hereof. 
 4.6 Distributions Pursuant to Domestic Relations Orders. Notwithstanding anything in the Plan to the
contrary, payments to an individual other than the Participant may be made as necessary to fulfill the requirements of a domestic relations order (as defined in Code Section 414(p)(1)(B)); provided, however, that in no event shall payments
pursuant to this Section 4.6 commence until such time as the Participant commences distribution of benefits in accordance with the applicable Plan terms. 
  

 14 

 4.7 Death Benefits. 
 (a) Post-Retirement Death Benefit. In the event of the death of the Participant after payments from the Plan have begun, the form
of such payments will determine the amount and duration of payments following the Participant’s death, if any, which shall be due from the Plan with respect to the Participant. 
 (b) Pre-Retirement Death Benefits 
 (i) Amount of Payment. In the event a Participant dies prior to commencing any payments under the Plan, in lieu of all other payments from the Plan, the Participant’s Spouse who is receiving or is entitled
to receive the Actual Death Benefit shall receive a monthly death benefit from the Plan equal to (A) the difference between the Actual Death Benefit and what the Actual Death Benefit would have been without regard to the Benefit Limitation,
determined solely for purposes of this Section 4.7 as if the Participant died at normal retirement age under the Pension Plan without any reductions, reduced by (B) the early commencement reduction factors and spouse’s age difference
or Qualified Joint and 50% Survivor Annuity factors that apply to the determination of the Actual Death Benefit, if any, except that for a Participant whose Actual Death Benefit is not payable to the Spouse prior to the Participant’s normal
retirement age, the applicable early commencement and Qualified Joint and 50% Survivor Annuity reduction factors shall be those that apply to the Actual Death Benefit for a Participant not eligible for early retirement under the Pension Plan at the
time of death. 
 (ii) Form of Payment. The Benefit payable pursuant to this Section 4.7(b) shall be payable in
the form of a Single Life Annuity for the life of the Spouse. 
 (iii) Timing of Payment. Payment of the amount payable
pursuant to this Section 4.7(b) shall be payable as soon as administratively feasible following the later of the Participant’s death or the date that the Participant would have attained age fifty-five (55), but in no event later than the
second pay processed thereafter pursuant to the Company’s routine payroll practices as in effect from time to time. 
  

 15 

 (c) Effect of a Change in Control. Notwithstanding anything in the foregoing to
the contrary, if a Participant becomes entitled to a Supplemental Pension Benefit pursuant to Section 4.5, but dies before the payment of such benefit, the Company shall pay to the Participant’s Spouse a single cash payment equal to the
aggregate Supplemental Pension Benefit described in Section 4.5. Such payment shall be made within thirty (30) days of the date of the Participant’s death. 
 4.8 409A Transition Rule. Notwithstanding anything herein to the contrary, the Participant’s Supplemental Pension Benefit shall be paid in the manner elected by the Participant under the terms of the
Pension Plan, provided that such election is made under the Pension Plan and payment commences under this Plan on or before December 31, 2008, or such later date as is permitted under Code Section 409A or regulations, rulings, or
applicable law issued thereunder. 
 4.9 Additional Procedures. The Committee, in its sole discretion, may establish additional
procedures and requirements for elections under the Plan and for payment of Supplemental Pension Benefits provided that they do not violate Code Section 409A.

such review, the Claimant (or his representative) shall be afforded reasonable opportunity to review pertinent documents, and may submit issues and comments in writing. In addition, the Claimant (or his representative) shall have the right to submit

of any appeal from an initial claim denial made pursuant to this Section 5.2, without regard to any state or federal statutes establishing provisions relating to limitations of actions. 
 (d) Failure to Follow Claims Procedure. If a Claimant does not follow the procedures set forth above, he shall be deemed to have
waived the right to appeal benefit determinations under the Plan. In addition, all determinations by and decisions of the Committee under this Section 5.2 shall be binding on and conclusive as to the Claimant. 
  

 19 

 5.3 No Right to Assets. Any Participant (or Participant’s beneficiary) who may have or claim
any interest in or right to any compensation, payment or benefit payable hereunder shall rely solely upon the unsecured promise of the Company as set forth herein for the payment thereof and shall have the status of a general unsecured creditor of
the Company. The Plan constitutes a mere promise by the Company to make certain benefit payments in the future. The right of any Participant or beneficiary to benefits hereunder is strictly contractual. Notwithstanding the foregoing provisions of
this Section 5.3, the Company may, in its discretion, establish a trust to pay amounts becoming payable by the Company pursuant to this Plan, which trust shall be subject to the claims of the general creditors of the Company in the event of its
bankruptcy or insolvency. Notwithstanding any establishment of such a trust, the Company shall remain responsible for the payment of any amounts so payable which are not so paid by such trust. If any such trust is established, the trustee will not
be required to invest trust assets in accordance with the directions of Participants given in accordance with this Plan, although the trustee, in its discretion, may so invest the trust assets. 
 5.4 No Contract of Employment. This Plan shall not be construed to establish a guarantee of future or continued employment by the Company of any
Participant. 
 5.5 Non-Alienation. Benefits payable under this Plan shall not be subject in any manner to anticipation, alienation,
sale, transfer, assignment, pledge, encumbrance, attachment or garnishment, whether voluntary or involuntary, and any attempt to anticipate, alienate, sell, transfer, assign, pledge, encumber, attach or garnish the same shall be void; nor shall any
such distribution or payment be in any way liable for or subject to the debts, contracts, liabilities, engagements or torts of any person entitled to such distribution or payment. If any Participant or Beneficiary is adjudicated bankrupt or purports
to anticipate, alienate, sell, transfer, assign, pledge, encumber, attach or garnish any such distribution or payment voluntarily or involuntarily, the Committee, in its discretion, may hold or cause to be held or applied such 

  

 20 

 
distribution or payment or any part thereof to or for the benefit of such Participant or Beneficiary in such manner as the Committee shall direct. The
provisions of this Section 5.5 shall not apply to any benefit payable pursuant to a “qualified domestic relations order,” as defined in Section 414(p) of the Code, which the Committee determines is applicable to any benefit
hereunder as referenced in Section 4.6. 
 5.6 Payments to Minors or Incompetents. If the Committee determines that any person
entitled to payments under the Plan is a minor or incompetent by reason of physical or mental disability, it may cause all payments thereafter becoming due to such person to be made to any other person for his benefit, without responsibility to
follow the application of amounts so paid. Payments made pursuant to this provision shall completely discharge the Company, the Plan, and the Committee. 
 5.7 No Effect on Other Compensation and Benefits. Nothing contained herein shall exclude or in any manner modify or otherwise affect any existing or future rights of any Participant to participate in and
receive the benefits of any compensation, bonus, pension, life insurance, medical or other employee benefit plan or program to which he otherwise might be or become entitled as an officer or employee of the Company. 
 5.8 No Amendment to Pension Plan. This Plan shall not be deemed to constitute an amendment to, or a part of, the Pension Plan. All references
hereunder to the Pension Plan shall include any amended or successor plan or plans maintained by the Company, the terms of which may be applicable at any time to a Participant’s defined benefit retirement benefit. If, however, the Pension Plan
terminates, merges with, or is replaced by a successor plan, and as a result thereof the amount of the Supplemental Pension Benefit to be paid to any Participant hereunder would be reduced or calculated on a different basis, or commence at a later
date or dates, such Supplemental Pension Benefit shall not be less than an amount calculated pursuant to the provisions of this Plan and in accordance with the terms of the Pension Plan, as in effect immediately prior to such termination, merger or
replacement. 
  

 21 

 5.9 Construction: Choice of Laws. The provisions of the Plan shall be construed, administered and
governed under the laws of the Commonwealth of Pennsylvania (including its statute of limitations provisions, but excluding its choice of law provisions) to the extent such laws are not preempted by ERISA or any other federal laws which may from
time to time be applicable. Whenever any words are used herein in the masculine gender, they shall be construed as though they were also used in the feminine gender in all cases where they would so apply, and whenever any words are used herein in
the singular form, they shall be construed as though they were also used in the plural form in all cases where they would so apply. Titles of Articles and Sections hereof are for convenience of reference only and are not to be taken into
account in construing the provisions of this Plan. 
 5.10 Invalidity of Provisions. If any provision of the Plan shall be held
illegal or invalid for any reason, said illegality or invalidity shall not affect the remaining parts of the Plan, but the Plan shall be construed and enforced as if said illegal and invalid provision had never been inserted herein. 
 5.11 Status. This Plan is not intended to satisfy the requirements for qualification under Section 401(a) of the Code. It is intended to
be a nonqualified plan that is not subject to ERISA except as required by applicable law. The Plan shall be construed and administered so as to effectuate this intent. 
 5.12 Expenses. The Company shall bear all expenses incurred by the Committee in administering this Plan. 
 5.13 Indemnification for Liability. The Company shall indemnify the Committee and the employees of the Company to whom the Committee delegates duties under this Plan, against any and all claims, losses, damages, expenses and
liabilities arising from their responsibilities in connection with this Plan, unless the same is determined to be due to gross negligence or willful misconduct. 
  

 22 

 5.14 Successors. To the extent not automatically assumed by operation of law, the Company shall
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 Company to expressly assume the Company’s obligations hereunder in the same
manner and to the same extent that the Company would be required to perform if no such succession had taken place. 
 5.15 Withholding
Requirements. Payment of benefits under this Plan shall be subject to applicable withholding requirements. 
 5.16 Amendment and
Termination. The Company expects to continue the Plan indefinitely, but specifically reserves the right, in the sole and unfettered discretion of its Board, at any time, to amend, in whole or in part, any or all of the provisions of the Plan and
to terminate the Plan in whole or in part, provided, however, that no such amendment or termination shall (a) reduce or adversely affect the benefits payable under the Plan to a Participant (or his Beneficiary) if the Participant’s
termination of employment with the Company has occurred prior to such termination or amendment of the Plan, or (b) reduce or adversely affect the benefit to be paid with respect to the Participant on the date of such termination or amendment,
as compared with the benefit that would have been payable with respect to the Participant if his employment had terminated on the day before the Plan was so terminated or amended. Termination of the Plan shall not be a distribution event under the
Plan. 
 5.17 Limitation of Liability. Notwithstanding any provision herein to the contrary, neither the Company, the Committee, nor
any individual acting as employee or agent of the Company or Committee, shall be liable to any Participant, former Participant, Beneficiary, or any other person for any claim, loss, liability or expense incurred in connection with the Plan, unless
attributable to fraud or willful misconduct on the part of the Company, Committee, or any such agent of the Company or Committee, or a breach by the Company or Committee of any provision of the Plan that results in a reduction of the benefit
provided hereunder. 
  

 23 

 5.18 409A Compliance. Prior to January 1, 2009, the Plan was intended to and was administered
to comply with the requirements of Code Section 409A, including good faith, reasonable statutory interpretations of Section 409A which occurred prior to the Plan’s amendment and restatement and which were contrary to the terms of the
Plan, if any. The Plan shall at all times be interpreted in a manner consistent with Section 409A. In the event that any provision that is necessary for the Plan to comply with Section 409A is determined by the Committee, in its sole
discretion, to have been omitted, such omitted provision shall be deemed to be included herein and is hereby incorporated as part of the Plan. 
 IN WITNESS WHEREOF, Mine Safety Appliances Company has caused the Mine Safety Appliances Company
Supplemental Pension Plan to be executed by its duly authorized officers this 19th day of December, 2008.
