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.

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 case of a pre-retirement death payment pursuant to Section 4.7).

1.28. “Spousal Consent” means written consent by a 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.

2.2 Each other Eligible Employee of the Company who was not participating in the Plan on December 31, 2004 for whom benefits under the Pension Plan are reduced as a result of the Benefit Limitation shall begin participating in the Plan on the first date the Benefit Limitation causes a reduction in the employee’s accrued benefit under the Pension Plan.

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.

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.

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.

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 19^th day of December, 2008.
