Item 1. Business
- ----------------

      Operating Segments:
      ------------------

      The company is organized into three geographic operating segments - North
America, Europe and Other International. Further information with respect to the
registrant's operating segments is reported at Note 7 of Notes to Consolidated
Financial Statements contained in the registrant's Annual Report to Shareholders
for the year ended December 31, 2000, incorporated herein by reference.

      Products and Markets:
      --------------------

      The primary business of the registrant and its affiliated companies is the
manufacture and sale of products designed to protect the safety and health of
people throughout the world.

      Principal products include respiratory protective equipment that is
air-purifying, air-supplied and self-contained in design; instruments that
monitor and analyze workplace environments and control industrial processes;
thermal imaging cameras that enable firefighters and rescue workers to see
through smoke and darkness; and personal protective products including head, eye
and face, hearing protectors, and fall protection equipment.

      Many of these products have wide application for workers in industries
that include manufacturing, municipal and volunteer fire departments, public
utilities, mining, chemicals, petroleum, construction, transportation, the
military, and hazardous materials clean-up. Consumer products target the growing
do-it-yourself market and are available through select home center retail
outlets under the MSA Safety Works(TM) brand.

      Other products manufactured and sold, which do not fall within the
category of safety and health equipment, include boron-based and other specialty
chemicals. Additional information concerning the registrant's products is
reported at Note 7 of Notes to Consolidated Financial Statements contained in
the registrant's Annual Report to Shareholders for the year ended December 31,
2000, incorporated herein by reference.

      The registrant and its affiliated companies compete with many large and
small enterprises. For most of the registrant's products and in most markets,
principal methods of competition are product features, quality and price. In the
opinion of management, the registrant is a leader in the manufacture of safety
and health


                                       3


equipment.

      Orders, except under contracts with U.S. government agencies, are
generally filled promptly after receipt and the production period for special
items is usually less than one year. The year-end backlog of orders under
contracts with U.S. government agencies was $14,582,000 in 2000, $10,225,000 in
1999 and $18,265,000 in 1998.

      Sales of products to U.S. government agencies decreased in 2000; however,
incoming orders were higher than shipments in both 2000 and 1999. The company's
business is not dependent on a single customer or group of related customers,
the loss of which would have a material adverse effect on the registrant's
results.

   Research:
   --------

      The registrant and its affiliated companies engage in applied research
with a view to developing new products and new applications for existing
products. Most of the products are designed and manufactured to meet currently
applicable performance and test standards published by groups such as ANSI
(American National Standards Institute), MSHA (Mine Safety & Health
Administration), NIOSH (National Institute for Occupational Safety and Health),
UL (Underwriters' Laboratories), SEI (Safety Equipment Institute), FM (Factory
Mutual), CEN (European Committee for Standardization) and CSA (Canadian
Standards Association). The registrant also from time to time engages in
research projects for others such as the Bureau of Mines and the Department of
Defense or its prime contractors. Registrant-sponsored research and development
costs were $17,241,000 in 2000, $17,097,000 in 1999, and $17,415,000 in 1998.

      In the aggregate, patents have represented an important element in
building the business of the registrant and its affiliates, but in the opinion
of management no one patent or group of patents is of material significance to
the business as presently conducted.

   General:
   -------

      The company was founded in 1914 and is headquartered in Pittsburgh,
Pennsylvania. As of December 31, 2000, the registrant and its affiliated
companies had approximately 4,000 employees, of which 2,100 were employed by
international affiliates. None of the U.S. employees are subject to the
provisions of a collective bargaining agreement.


                                       4


      In the United States and in those countries in which the registrant has
affiliates, its products are sold by its own salespersons, independent
distributors and/or manufacturers' representatives. In international countries
where the registrant has no affiliate, products are sold primarily through
independent distributors located in those countries.

      The registrant is cognizant of environmental responsibilities and has
taken affirmative action regarding this responsibility. There are no current or
expected legal proceedings or expenditures with respect to environmental matters
which would materially affect the operations of the registrant and its
affiliates.

      Generally speaking, the operations of the registrant and its affiliates
are such that it is possible to maintain sufficient inventories of raw materials
and component parts on the manufacturing premises.

      Equipment and machinery for processing chemicals and rubber, plastic
injection molding equipment, molds, metal cutting, stamping and working
equipment, assembly fixtures and similar items are regularly acquired, repaired
or replaced in the ordinary course of business at prevailing market prices as
necessary.

      Further information about the registrant's business is included in
Management's Discussion and Analysis at pages 14 to 17 of the 2000 Annual Report
to Shareholders, incorporated herein by reference.

            Section 1.03. Special Meetings. Except as other-wise required by law
                          ----------------
and subject to the rights of the holders of any class or series of preferred
stock with respect to any vote of the holders of such class or series when
voting by class, special meetings of shareholders of the Company may be called
only by the Board of Directors pursuant to a resolution approved by a majority
vote of the Disinterested Directors (as that term is defined in the Restated
Articles). [Restated Articles Section 12.03] Special meetings shall be held at
such place as may be designated by the Board of Directors, or if not so
designated, at the principal office of the Company.

            Section 1.04. Business at Special Meetings. No business may be
                          ----------------------------
transacted at any special meeting of share-holders other than that the general
nature of which has been stated in the notice of meeting, and business which is
incidental or germane thereto.

            Section 1.05. Notice of Shareholders' Meetings. Written notice
                          --------------------------------
specifying the place, date and time of each meeting of the shareholders and the
purpose or purposes for which the meeting is called shall be given to all
share-holders of record entitled to vote at such meeting at least ten days
before the day named for the meeting.

            Section 1.06. Quorum; Organization. A share-holders' meeting duly
                          --------------------
called shall not be organized for the transaction of business unless a quorum is
present. At any meeting the presence in person or by proxy of shareholders
entitled to cast at least a majority of the votes which all shareholders are
entitled to cast on the particular matter shall be necessary and sufficient to
constitute a quorum for the purpose of considering such matter. The shareholders
present at a duly organized meeting can continue to do business until
adjournment, notwithstanding the withdrawal of enough shareholders to leave less
than a majority. If a meeting


                                      -5-


cannot be organized because a quorum has not attended, those present in person
or by proxy may adjourn the meeting to such time and place as they may
determine, without notice other than announcement at the meeting, until a quorum
as aforesaid shall be present; and in the case of any meeting called for the
election of directors, such meeting may be adjourned only from day to day, or
for such longer periods not exceeding fifteen days each, as may be directed by
shareholders who are present in person or by proxy, and those who attend the
second of such adjourned meetings, although entitled to cast less than a
majority of the votes which all outstanding shares are entitled to cast, shall
nevertheless constitute a quorum for the purpose of electing directors. The
Chairman, or in his absence, the President, shall preside, and the Secretary
shall take the minutes, at all meetings of the shareholders. In the absence of
the foregoing officers the presiding officer shall be designated by the Board of
Directors or if not so designated selected by the shareholders present; and in
the absence of the Secretary, the presiding officer shall designate any person
to take the minutes of the meeting.

            Section 1.07. Vote Required; Meeting Procedure. When a quorum is
                          --------------------------------
present at any meeting, the vote of share-holders present, in person or by
proxy, entitled to cast at least a majority of the votes which al shareholders
present and voting (excluding abstentions) are entitled to cast on the
particular matter shall decide any question brought before such meeting, except
that (a) if the question is one upon which, by express provision of statute or
of the Restated Articles, a different or additional vote is required, such
express provision shall govern, (b) all elections shall be determined by a
plurality of the votes cast, and (c) in the case or privileged, subsidiary or
incidental motions or questions involving the convenience of the shareholders
present, the Chairman may call for a per capita vote, either by voice or by show
of hands. Elections for directors need not be by


                                      -6-


ballot, unless otherwise ordered by the presiding officer at the meeting or
unless a demand is made by a shareholder at the meeting and before the voting
begins. The chairman of any meeting shall determine the order of business and
the procedure at the meeting, including such regulation of the conduct of
discussion as seems to him in order. The conduct of meetings shall be governed
by accepted corporate practice, the fundamental rule being that all who are
entitled to take part shall be treated with fairness and good faith.

            Section 1.08. Proxies; Appointment and Revocation. Every shareholder
                          -----------------------------------
entitled to vote at a meeting of shareholders or to express consent or dissent
to corporate action in writing without a meeting may authorize another person or
persons, but not more than three, to act for him by proxy. Every proxy shall be
appointed by an instrument in writing (including telegram, cable or radio-gram,
telex or similar transmission), executed by such shareholder or by his
authorized attorney, and filed with the Secretary of the Company. A proxy shall
not be revoked by the death or incapacity of the maker unless, before the vote
is counted or the proxy is exercised, written notice of such death or incapacity
is given to the Secretary of the Company.

Directors by a majority vote of the Disinterested Directors then in office shall
determine which class shall contain an unequal number of directors. At the
annual meeting of shareholders to be held in 1986, separate elections shall be
held for the directors of each class, the term of office of directors of the
first class to expire at the first annual meeting after their election; the term
of office of the directors of the second class to expire at the second annual

annual election of directors or of such class of directors shall vote in favor
of such removal; provided, however, that the shareholders shall have such power
of removal without cause only if and so long as the general corporate law of the
Company's state of incorporation specifically mandates such power. If such power
of removal without cause is not mandated by statute, the share-holders may
remove a director or directors from office at any time


                                      -8-

Owned by an Acquiring Person [Restated Articles Section 10.1(c)]

            (d) Vacancies. Vacancies in the Board of Directors, including
                ---------
vacancies resulting from an increase in the number of directors, shall be filled
only by a majority vote of the Disinterested Directors then in office, though
less than a quorum, except as otherwise required by law. All directors elected
to fill vacancies shall hold office for a term expiring at the annual meeting of
shareholders at which the term of the class to which they have been elected
expires. No decrease in the number of directors constituting the Board of
Directors shall shorten the term of an incumbent director. [Restated Articles

director or directors elected by such holders of preferred stock. [Restated
Articles Section 10.1(f)]

election; otherwise from the time he accepts office or attends his first meeting
of the Board.

                       [Approved by Shareholders 4/24/87.]

            Section 7.01.  Indemnification of Directors, Officers and Others.
                           -------------------------------------------------

            (a) Right to Indemnification. Except as prohibited by law, every
                ------------------------
Director and officer of the Company shall be entitled as


                                      -23-


of right to be indemnified by the Company against expenses and any liability
paid or incurred by such person in connection with any actual or threatened
claim, action, suit or proceeding, civil, criminal, administrative,
investigative or other, whether brought by or in the right of the Company or
otherwise, in which he or she may be involved, as a party or otherwise, by
reason of such person being or having been a Director or officer of the Company
or by reason of the fact that such person is or was serving at the request of
the Company as a director, officer, employee, fiduciary or other representative
of another corporation, partnership, joint venture, trust, employee benefit plan
or other entity (such claim, action, suit or proceeding hereinafter being
referred to as "Action"); provided that no such right or indemnification shall
exist with respect to an Action brought by an indemnitee (as hereinafter
defined) against the Company except as provided in the last sentence of this
Subsection (a). Persons who are not directors or officers of the Company may be
similarly indemnified in respect of service to the Company or to another such
entity at the request of the Company to the extent the Board of Directors at any
time denominates any of such persons as entitled to the benefits of this
Section. As used in this Section 7.01, "indemnitee" shall include each Director
and officer of the Company and each other person denominated by the Board of
Directors as entitled to the benefits of this Section, "expenses" shall include
fees and expenses of counsel selected by any such indemnitee and "liability"
shall include amounts of judgments, excise taxes, fines, penalties and amounts
paid in settlement. An indemnitee shall be entitled to be indemnified pursuant
to this Subsection (a) for expenses incurred in connection with any Action
brought by an indemnitee against the Company only (i) as provided under
Subsection (c) of this Section, (ii) if the indemnitee is successful in whole or
in part in the Action for which expenses are claimed or (iii) if the
indemnification for expenses is included in a settlement of the Action or is
awarded by a court.


                                      -24-


            (b) Right to Advancement of Expenses. Every indemnitee shall be
                --------------------------------
entitled as of right to have his or her expenses in defending any Action or in
any Action under Subsection (c) paid in advance by the Company prior to final
disposition of such Action, subject to any obligation which may be imposed by
law or by provision in the Articles, By-Laws, agreement or otherwise to
reimburse the Company in certain events.

            (c) Right of Indemnitee to Initiate Action. If a written claim under
                --------------------------------------
Subsection (a) or Subsection (b) of this Section is not paid in full by the
Company within thirty days after such claim has been received by the Company,
the indemnitee may at any time thereafter initiate an Action against the Company
to recover the unpaid amount of the claim and, if successful in whole or in
part, the indemnitee shall also be entitled to be paid the expense of
prosecuting such Action. The only defense to any Action to recover a claim under
Subsection (a) of this Section shall be that the indemnitee's conduct was such
that under Pennsylvania law the Company is prohibited from indemnifying the
indemnitee for the amount claimed, but the burden of proving such defense shall
be on the Company. Neither the failure of the Company (including its Board of
Directors, independent legal counsel and its shareholders) to have made a
determination prior to the commencement of such suit that indemnification of the
indemnitee is proper in the circumstances, nor an actual determination by the
Company (including its Board of Directors, independent legal counsel or its
shareholders) that the indemnitee's conduct was such that indemnification is
prohibited by law, shall be a defense to such Action or create a presumption
that the indemnitee's conduct was such that indemnification is prohibited by
law. The only defense to any such Action to receive payment of expenses in
advance under Subsection (b) of this Section shall be failure to make an


                                      -25-


undertaking to reimburse if such an undertaking is required by law or by
provision in the Articles, By-Laws, agreement or otherwise.

            (d) Insurance and Funding. The Company may purchase and maintain
                ---------------------
insurance to protect itself and any person eligible to be indemnified hereunder
against any liability or expense asserted or incurred by such person in
connection with any Action, whether or not the Company would have the power to
indemnify such person against such liability or expense by law or under the
provisions of this Section. The Company may create a trust fund, grant a
security interest, cause a letter of credit to be issued or use other means
(whether or not similar to the foregoing) to ensure the payment of such sums as
may become necessary to effect indemnification a provided herein.

            (e) Non-Exclusivity; Nature and Extent of Rights. The right of
                --------------------------------------------
indemnification and advancement of expenses provided for in this Section (i)
shall not be deemed exclusive of any other rights, whether now existing or
here-after created, to which any indemnitee may be entitled under any agreement
or by-law, charter provision, vote of share-holders or directors or otherwise
(ii) shall be deemed to create contractual rights in favor of each indemnitee,
(iii) shall continue as to each person who has ceased to have the status
pursuant to which he or she was entitled or was denominated as entitled to
indemnification under this Section and shall inure to the benefit of the heirs
and legal representatives of each indemnitee and (iv) shall be applicable to
Actions commenced after the adoption of this Section, whether arising from acts
or omissions occurring before or after the adoption of this Section. The rights
of indemnification and advancement of expenses provided for in this Section may
not be amended or repealed so as to limit in any way the indemnification or the
right to advancement of expenses provided for in this Section with respect to
any acts


                                      -26-


or omissions occurring prior to the adoption of any such amendment or repeal.

            (f) Effective Date. This Section 7.01 shall apply to every Action
                --------------
other than an Action filed prior to January 27, 1987, except that it shall not
apply to the extent that Pennsylvania law does not permit its application to any
breach of performance of duty or any failure of performance of duty by an
indemnitee occurring prior to January 27, 1987. [Approved by Shareholders

            Section 7.02 Personal Liability of Directors.
                         -------------------------------

            (a) To the fullest extent that the laws of the Commonwealth of
Pennsylvania, as in effect on January 27, 1987 or as thereafter amended, permit
elimination or limitation of the liability of directors, no Director of the
Company shall be personally liable for monetary damages as such for any action
taken, or any failure to take any action, as a Director.

            (b) This Section 7.02 shall not apply to any actions filed prior to
January 27, 1987, nor to any breach of performance of duty or any failure of
performance of duty by any Director of the Company occurring prior to January
27, 1987. The provisions of this Section shall be deemed to be a contract with
each Director of the Company who serves as such at any time while this Section
is in effect and each such Director shall be deemed to be doing so in reliance
on the provisions of this Section. Any amendment or repeal of this Section or
adoption of any other By-Law or provision of the Articles of the Company which
has the effect of increasing Director liability shall operate prospectively only
and shall not affect any action taken, or any failure to act, prior to the
adoption of such amendment, repeal, other By-Law or provision.

                         MINE SAFETY APPLIANCES COMPANY
                         RETIREMENT PLAN FOR DIRECTORS,

                    As Amended Effective as of April 1, 2001
                    ----------------------------------------

            1. Purpose. The purpose of this plan, as originally established
               -------
December 17, 1987, was to provide to each individual serving as a member of the
Board of Directors from time to time (individually referred to as a "Director"
and collectively as the "Board") of Mine Safety Appliances Company (the
"Company"), a lifetime retirement benefit following the attainment of certain
age and service requirements described hereafter. Effective April 1, 2001, the
Plan was amended to freeze benefits as of that date.

            2. Eligibility. A Director who has terminated his or her service on
               -----------
the Board, whether before or after April 1, 2001, after completing at least 5
years of service as a Director shall be entitled to an annual "Retirement
Allowance" during his or her lifetime, as described below, when his or her
combined age and service as a Director, whether before or after April 1, 2001,
satisfy the "Rule of 75". The "Rule of 75" shall be satisfied when the sum of
the Director's age (measured in full and partial years, in increments of
one-twelfth (1/12) year) and the Director's years of service as a Director
(measured in full and partial years, in increments of one-twelfth (1/12) year)
equals or exceeds 75. A Director who has not terminated his or her service but
has satisfied the "Rule of 75" as described herein shall have a vested right to
an annual "Retirement Allowance" during his or her lifetime, as described below.

            3. Retirement Allowance. Subject to Section 4 hereof, the amount of
               --------------------
the annual Retirement Allowance paid to a retired Director shall be equal to
$20,000 multiplied by a fraction of which the numerator is the Director's years
of service (measured as provided in Section 2) as of March 31, 2001 and the
denominator is the Director's years of service (whether before or after March
31, 2001) required to satisfy the "Rule of 75." The amount of the annual
Retirement Allowance, as so computed, for each eligible Director serving on the
Board as of March 31, 2001 is shown in the attached Schedule. The annual
Retirement Allowance shall be paid in four equal installments as of the first
day of each calendar quarter, beginning with the calendar quarter following the
Director's termination of service and including the calendar quarter in which
the Director's death occurs. No Retirement Allowance payments shall be made
following the death of a retired Director.

            4. Effect of Change in Control. Notwithstanding any other provision
               ---------------------------
of this Plan, if a Director is vested in his or her Retirement Allowance on the
date of the Director's termination of service and that termination date occurs
on,


or within the three-year period immediately following, a Change in Control (as
defined in this Section 4), then, not later than the fifth (5th) business day
following such termination date, the Company shall pay the Director a lump sum
amount equal to the actuarial equivalent of the Director's Retirement Allowance
(in lieu of making payment of such Retirement Allowance in accordance with
Section 3 hereof). For purposes of this Section 4, "actuarial equivalent" shall
be determined using the same assumptions utilized under the Non-Contributory
Pension Plan for Employees of Mine Safety Appliances Company (or successor plan
thereto) immediately prior to the Director's termination date, or, if more
favorable to the Director, immediately prior to the Change in Control.

            Change in Control shall be deemed to have occurred if the event set
            -----------------
forth in any one of the following paragraphs shall have occurred:

                        (I) any Person (as defined in this Section 4) is or
            becomes the Beneficial Owner (as defined in this Section 4),
            directly or indirectly, of securities of the Company (not including
            in the securities beneficially owned by such Person any securities
            acquired directly from the Company or its Affiliates (which term
            shall have the meaning set forth in Rule 12b-2 promulgated under
            Section 12 of the Exchange Act, as defined in this Section 4))
            representing thirty percent (30%) or more of the combined voting
            power of the Company's then outstanding securities, excluding any
            Person who becomes such a Beneficial Owner in connection with a
            transaction described in clause (I) of paragraph (III) below; or

                        (II) the following individuals cease for any reason to
            constitute a majority of the number of directors then serving:
            individuals who, on May 5, 1998, constitute the Board and any new
            director (other than a director whose initial assumption of office
            is in connection with an actual or threatened election contest,
            including but not limited to a consent solicitation, relating to the
            election of directors of the Company) whose appointment or election
            by the Board or nomination for election by the Company's
            shareholders was approved or recommended by a vote of at least
            two-thirds (2/3) of the directors then still in office who either
            were directors on May 5, 1998 or whose appointment, election or
            nomination for election was previously so approved or recommended;
            or

                        (III) there is consummated a merger or consolidation of
            the Company or any direct or indirect subsidiary of the Company with
            any other corporation, other than (I) a merger or consolidation


                                      -2-


            which would result in the voting securities of the Company
            outstanding immediately prior to such merger or consolidation
            continuing to represent (either by remaining outstanding or by being
            converted into voting securities of the surviving entity or any
            parent thereof), in combination with the ownership of any trustee or
            other fiduciary holding securities under an employee benefit plan of
            the Company or any subsidiary of the Company, at least fifty-one
            percent (51%) of the combined voting power of the securities of the
            Company or such surviving entity or any parent thereof outstanding
            immediately after such merger or consolidation, or (ii) a merger or
            consolidation effected to implement a recapitalization of the
            Company (or similar transaction) in which no Person is or becomes
            the Beneficial Owner, directly or indirectly, of securities of the
            Company representing thirty percent (30%) or more of the combined
            voting power of the Company's then outstanding securities; or

                        (IV) the shareholders of the Company approve a plan of
            complete liquidation or dissolution of the Company or there is
            consummated an agreement for the sale or disposition by the Company
            of all or substantially all of the Company's assets, other than a
            sale or disposition by the Company of all or substantially all of
            the Company's assets to an entity, at least fifty-one percent (51%)
            of the combined voting power of the voting securities of which are
            owned by shareholders of the Company in substantially the same
            proportions as their ownership of the Company immediately prior to
            such sale.

Notwithstanding the foregoing, a Change in Control shall not be deemed to have
occurred by virtue of the consummation of any transaction or series of
integrated transactions immediately following which the record holders of the
common stock of the Company immediately prior to such transaction or series of
transactions continue to have substantially the same proportionate ownership in
an entity which owns all or substantially all of the assets of the Company
immediately following such transaction or series of transactions.

      Beneficial Owner shall have the meaning set forth in Rule 13d-3 under the
      ----------------
Exchange Act.

      Exchange Act shall mean the Securities and Exchange Act of 1934, as
      ------------
amended from time to time.

      Person shall have the meaning given in Section 3(a)(9) of the Exchange
      ------
Act, as modified and used in Sections 13(d) and 14(d) thereof, except that such

                                      -3-


not include (I) the Company or any of its subsidiaries, (ii) a trustee or other
fiduciary holding securities under an employee benefit plan of the Company or
any of its Affiliates, (iii) an underwriter temporarily holding securities
pursuant to an offering of such securities, or (iv) a corporation owned,
directly or indirectly, by the shareholders of the Company in substantially the

individual or entity [including the trustees (in such capacity) of any such
entity which is a trust] which is, directly or indirectly, the Beneficial Owner
of securities of the Company representing five percent (5%) or more of the
combined voting power of the Company's then outstanding securities immediately
before the date hereof or any Affiliate of any such individual or entity,
including, for purposes of this Plan, any of the following: (A) any trust
(including the trustees thereof in such capacity) established by or for the
benefit of any such individual; (B) any charitable foundation (whether a trust
or a corporation, including the trustees or directors thereof in such capacity)

            5. Source of Payments. This plan shall not be formally funded; a
               ------------------

                         MINE SAFETY APPLIANCES COMPANY

                 1990 NON-EMPLOYEE DIRECTORS' STOCK OPTION PLAN

                      (As amended effective April 1, 2001)

      The purposes of the 1990 Non-Employee Directors' Stock Option Plan (the
"Plan") are to promote the long-term success of Mine Safety Appliances Company
(the "Company") by creating a long-term mutuality of interests between the
non-employee Directors and shareholders of the Company, to provide an additional
inducement for such Directors to remain with the Company and to provide a means
through which the Company may attract able persons to serve as Directors of the
Company.

                                    SECTION 1
                                 Administration

      The Plan shall be administered by a Committee (the "Committee") appointed
by the Board of Directors of the Company (the "Board") and consisting of not
less than two members of the Board. The Committee shall keep records of action
taken at its meetings. A majority of the Committee shall constitute a quorum at
any meeting, and the acts of a majority of the members present at any meeting at
which a quorum is present, or acts approved in writing by a majority of the
Committee, shall be the acts of the Committee.

      The Committee shall interpret the Plan and prescribe such rules,
regulations and procedures in connection with the operations of the Plan as it
shall deem to be necessary and advisable for the administration of the Plan
consistent with the purposes of the Plan. All questions of interpretation and
application of the Plan, or as to stock options or restricted stock awards
granted under the Plan, shall be subject to the determination of the Committee,
which shall be final and binding.

      Notwithstanding the above, the selection of the Directors to whom stock
options and restricted stock awards are to be granted, the timing of such
grants, the number of shares subject to any stock option or restricted stock
award, the exercise price of any stock option, the periods during which any
stock option may be exercised or a restricted stock award shall be subject to
restriction and the term of any stock option shall be as hereinafter provided,
and the Committee shall have no discretion as to such matters.

                                    SECTION 2
                         Shares Available under the Plan

      The aggregate number of shares which may be issued and as to which grants
of stock options and restricted stock awards may be made under the Plan is
150,000 shares of the Common Stock, without par value, of the Company (the
"Common Stock"), subject to adjustment and substitution as set forth in Section
6. If any stock option granted under the Plan is cancelled by mutual consent or
terminates or expires for any reason without having been exercised in full, the
number of shares subject thereto shall again be available for purposes of the
Plan. If shares of Common Stock are forfeited to the Corporation pursuant to the
restrictions


applicable to restricted stock, the shares so forfeited shall again be available
for purposes of the Plan. The shares which may be issued under the Plan may be
either authorized but unissued shares or treasury shares or partly each, as
shall be determined from time to time by the Board.

                                    SECTION 3
                   Grant of Stock Options and Restricted Stock

      On the third business day following the day of each annual meeting of the
shareholders of the Company (the "Grant Date"), each person who is then a member
of the Board and who is not then an employee of the Company or any of its
subsidiaries (a "non-employee Director") shall automatically and without further
action by the Board or the Committee be granted:

            (1) a "nonstatutory stock option" (i.e., a stock option which does
      not qualify under Section 422 of the Internal Revenue Code of 1986 (the
      "Code")) to purchase a number of shares of Common Stock determined by
      dividing 75% of the amount of the annual Director's retainer then in
      effect by the Grant Date per share value of the option as determined by
      the Company under the Black-Scholes option pricing model; and

            (2) a number of restricted shares of Common Stock ("restricted
      stock") determined by dividing 25% of the amount of the annual Director's
      retainer then in effect by the Fair Market Value of a share of Common
      Stock on the Grant Date.

The numbers of shares determined under the above formulas shall be rounded to
the nearest whole share. If on any Grant Date the number of shares remaining
available under the Plan is not sufficient for each non-employee Director to be
granted the full number of options and shares of restricted stock provided in
this Section, then the available shares shall be allocated among the options and
shares of restricted stock to be granted to each non-employee Director in
proportion to the amounts determined under the above formulas, disregarding any
fractions of a share.

                                    SECTION 4
                      Terms and Conditions of Stock Options

      Stock options granted under the Plan shall be subject to the following
terms and conditions:

            (A) The purchase price at which each stock option may be exercised
      (the "option price") shall be one hundred percent (100%) of the Fair
      Market Value per share of the Common Stock covered by the stock option on
      the Grant Date.

            (B) The option price for each stock option shall be paid in full
      upon exercise and shall be payable in cash in United States dollars
      (including check, bank draft or money order); provided, however, that in
      lieu of such cash the person exercising the stock option may pay the
      option price in whole or in part by delivering to the Company shares of
      the Common Stock having a Fair Market Value on the date of exercise of the
      stock option equal to the option price for the shares being purchased;
      except that (i) any portion of the option price representing a fraction of
      a share shall in any event be paid in cash and (ii) no shares of the
      Common Stock which have been held for less than one year may be


                                      -2-


      delivered in payment of the option price of a stock option. The date of
      exercise of a stock option shall be determined under procedures
      established by the Committee, and as of the date of exercise the person
      exercising the stock option shall be considered for all purposes to be the
      owner of the shares with respect to which the stock option has been
      exercised. Payment of the option price with shares shall not increase the
      number of shares of the Common Stock which may be issued under the Plan as
      provided in Section 2.

            (C) No stock option shall be exercisable by a grantee during the
      first six months of its term except in case of death or Disability.
      Subject to the terms of Section 4(E) providing for earlier termination of
      a stock option, no stock option shall be exercisable after the expiration
      of ten years from the Grant Date. A stock option to the extent exercisable
      at any time may be exercised in whole or in part.

            (D) No stock option shall be transferable by the grantee otherwise
      than by Will, or if the grantee dies intestate, by the laws of descent and
      distribution of the state of domicile of the grantee at the time of death.
      All stock options shall be exercisable during the lifetime of the grantee
      only by the grantee or the grantee's guardian or legal representative.

            (E) Subject to Section 4(C), if a grantee ceases to be a Director of
      the Company for any reason, any outstanding stock options held by the
      grantee shall be exercisable and shall terminate according to the
      following provisions:

                  (i) If a grantee ceases to be a Director of the Company for
            any reason other than resignation, removal for cause or death, any
            then outstanding stock option held by such grantee shall be
            exercisable by the grantee (whether or not exercisable by the
            grantee immediately prior to ceasing to be a Director) at any time
            prior to the expiration date of such stock option or within five
            years after the date the grantee ceases to be a Director, whichever
            is the shorter period;

                  (ii) If during his term of office as a Director a grantee
            resigns from the Board or is removed from office for cause, any
            outstanding stock option held by the grantee which is not
            exercisable by the grantee immediately prior to resignation or
            removal shall terminate as of the date of resignation or removal,
            and any outstanding stock option held by the grantee which is
            exercisable by the grantee immediately prior to resignation or
            removal shall be exercisable by the grantee at any time prior to the
            expiration date of such stock option or within 90 days after the
            date of resignation or removal, whichever is the shorter period;

                  (iii) Following the death of a grantee during service as a
            Director of the Company, any outstanding stock option held by the
            grantee at the time of death (whether or not exercisable by the
            grantee immediately prior to death) shall be exercisable by the
            person entitled to do so under the Will of the grantee, or, if the
            grantee shall fail to make testamentary disposition of the stock
            option or shall die intestate, by the legal representative of the
            grantee at any time prior to the expiration date of such stock
            option or within five years after the date of death, whichever is
            the shorter period;


                                      -3-


                  (iv) Following the death of a grantee after ceasing to be a
            Director and during a period when a stock option is exercisable, any
            outstanding stock option held by the grantee at the time of death
            shall be exercisable by such person entitled to do so under the Will
            of the grantee or by such legal representative (but only to the
            extent the stock option was exercisable by the grantee immediately
            prior to the death of the grantee) within one year after the date of
            death or, if applicable, within the period provided in Section
            4(E)(i), whichever is the longer period, but not later than the
            expiration date of such stock option.

      A stock option held by a grantee who has ceased to be a Director of the
      Company shall terminate upon the expiration of the applicable exercise
      period, if any, specified in this Section 4(E).

            (F) All stock options shall be confirmed by an agreement, or an
      amendment thereto, which shall be executed on behalf of the Company by the
      Chief Executive Officer (if other than the President), the President or
      any Vice President and by the grantee.

            (G) The obligation of the Company to issue shares of the Common
      Stock under the Plan shall be subject to (i) the effectiveness of a
      registration statement under the Securities Act of 1933, as amended, with
      respect to such shares, if deemed necessary or appropriate by counsel for
      the Company, (ii) the condition that the shares shall have been listed (or
      authorized for listing upon official notice of issuance) upon each stock
      exchange, if any, on which the Common Stock shares may then be listed and
      (iii) all other applicable laws, regulations, rules and orders which may
      then be in effect.

Subject to the foregoing provisions of this Section 4 and the other provisions
of the Plan, any stock option granted under the Plan may be subject to such
restrictions and other terms and conditions, if any, as shall be determined, in
its discretion, by the Committee and set forth in the agreement referred to in
Section 4(F), or an amendment thereto.

                                    SECTION 5
                    Terms and Conditions of Restricted Stock

      Restricted stock awards granted under the Plan shall be subject to the
following terms and conditions:

            (A) As of the Grant Date of the restricted stock award, certificates
      representing the shares of restricted stock shall be issued in the name of
      the Director and held by the Company in escrow until the earlier of the
      forfeiture of the shares of restricted stock to the Company or the lapse
      of the service restriction with respect to such shares. The Director shall
      execute and deliver to the Company a blank stock power in form acceptable
      to the Company with respect to each of the certificates representing the
      shares of restricted stock. Such stock power shall be returned to the
      Director if the service restriction lapses with respect to the shares to
      which the stock power relates.


                                      -4-


            (B) The Director shall not sell, exchange, assign, alienate, pledge,
      hypothecate, encumber, charge, give, transfer or otherwise dispose of,
      either voluntarily or by operation of law, any shares of restricted stock,
      or any rights or interests appertaining thereto, prior to the lapse of the
      service restriction imposed thereon and the issuance or transfer to the
      Director of certificates with respect to such shares, except that, subject
      to the provisions of Section 5(F), shares of restricted stock may be
      transferred by the Director by Will or, if the Director dies intestate, by
      the laws of descent and distribution of the state of domicile of the
      Director at the time of death.

            (C) As of the Grant Date, the Director shall be a shareholder of the
      Company with respect to the restricted stock and shall have all the rights
      of a shareholder with respect to the restricted stock, including the right
      to vote the restricted stock and to receive all dividends and other
      distributions paid with respect to such restricted stock, subject to the
      restrictions of the Plan and the restricted stock agreement, including
      without limitation the restriction that, with the exception of regular
      quarterly dividends payable in cash, all dividends and distributions on
      the restricted stock, whether paid in cash, Common Stock or other
      securities or property will be held in escrow subject to the same
      restrictions as the restricted stock.

            (D) If the Director's service as a Director of the Company
      terminates for any reason, other than as a result of the Director's death,
      Disability or Retirement, prior to the date of the third Annual Meeting of
      Shareholders of the Company following the Grant Date, then 100% of the
      shares of restricted stock awarded on the Grant Date shall, upon such
      termination of service and without any further action, be forfeited to the
      Company by the Director and cease to be issued and outstanding shares of
      Common Stock.

            If the Director remains a Director of the Company until the date of
      the third Annual Meeting following the Grant Date and the shares of
      restricted stock have not been previously forfeited to the Company
      pursuant to Section 5(E), the service restriction on 100% of the shares of
      restricted stock originally awarded on that Grant Date shall lapse, and a
      certificate representing such shares shall be issued or transferred by the
      Company to the Director. If the Director's service with the Company or a
      Subsidiary terminates as a result of the Director's death, Disability or
      Retirement, the service restriction imposed on any shares of restricted
      stock set forth above which have not been previously forfeited to the
      Company pursuant to Section 5(E) and on which the service restriction has
      not previously lapsed shall lapse, and a certificate representing such
      shares shall be issued or transferred by the Company to the Director (or
      the Director's personal representative).

            (E) Following the lapse of the service restriction on shares of
      restricted stock and the issuance or transfer of certificates representing
      such shares (and subject to Section 5(G) hereof), the Director shall not
      sell, exchange, assign, alienate, pledge, hypothecate, encumber, charge,
      give, transfer or otherwise dispose of ("transfer"), either voluntarily or
      by operation of law, any such shares or any rights or interests
      appertaining thereto and, in the case of death of the Director, the
      Director's personal representative shall not transfer such shares or any
      such rights or interests in accordance with the Director's Will, or if the
      Director dies intestate, with the laws of descent and distribution,
      without first offering to sell such shares to the Company at a price equal
      to the Fair


                                      -5-


      Market Value of the shares on the date of the mailing of the offer by the
      Director (or the Director's personal representative) to the Company. The
      Director (or within 90 days of the Director's death, the Director's
      personal representative) shall offer such shares to the Company for a
      period of 30 days by giving written notice by certified mail to the
      Company at its principal executive offices to the attention of its Vice
      President - Finance. Such offer may be accepted by the Company by
      delivering written notice of acceptance to the Director (or the Director's
      personal representative) by certified mail during the 30-day period during
      which the offer remains open. The date such notice is postmarked shall be
      deemed the date of acceptance. The purchase of the restricted stock shall
      be consummated, and payment in full for the shares purchased shall be
      made, at the principal executive offices of the Company in the United
      States on such date and at such time as may be reasonably designated by
      the Company in such written notice delivered to the Director (or the
      Director's personal representative), but not later than 30 days following
      the date of such written notice. Upon receipt of the purchase price, the
      Director (or the Director's personal representative) shall assign,
      transfer and deliver to the Company the certificates for the purchased
      restricted stock, duly endorsed, with all necessary stock transfer tax
      stamps duly affixed, together with any and all of the documents required
      effectively to transfer such restricted stock. If the Company does not
      accept the offer of the Director (or the Director's personal
      representative) within the required period, the Director (or the
      Director's personal representative) may transfer the restricted stock so
      offered, and such restricted stock shall no longer be subject to the
      Company's right of first refusal. If, at the date of death of the
      Director, the Director has previously offered shares to the Company
      pursuant to this Section 5(F) and the Company did not accept such offer,
      the Director's personal representative may transfer such shares without
      again offering such shares to the Company pursuant to this Section 5(F).

            (F) Each certificate representing shares of restricted stock shall
      have noted on the face of such certificate the following legend:

                  "Notice is hereby given that the shares of stock represented
            by this certificate are held subject to, and may not be transferred
            except in accordance with, the Mine Safety Appliances Company 1990
            Non-Employee Directors' Stock Option Plan and a restricted stock
            agreement executed thereunder, copies of which are on file at the
            office of Mine Safety Appliances Company."

            (G) All restricted stock awards shall be confirmed by an agreement,
      or an amendment thereto, which shall be executed on behalf of the Company
      by the Chief Executive Officer (if other than the President), the
      President or any Vice President and by the grantee.

Subject to the foregoing provisions of this Section 5 and the other provisions
of the Plan, any restricted stock award granted under the Plan may be subject to
such additional restrictions and other terms and conditions, if any, as shall be
determined, in its discretion, by the Committee and set forth in the agreement
referred to in Section 5(G), or an amendment thereto.


                                      -6-


                                    SECTION 6
                      Adjustment and Substitution of Shares

      If a dividend or other distribution shall be declared upon the Common
Stock payable in shares of the Common Stock, the number of shares of the Common
Stock set forth in Section 3, the number of shares of the Common Stock then
subject to any outstanding stock options and the number of shares of the Common
Stock which may be issued under the Plan but are not then subject to outstanding
stock options or restricted stock awards shall be adjusted by adding thereto the
number of shares of the Common Stock which would have been distributable thereon
if such shares had been outstanding on the date fixed for determining the
shareholders entitled to receive such stock dividend or distribution. Shares of
Common Stock so distributed with respect to any restricted stock held in escrow
shall also be held by the Company in escrow and shall be subject to the same
restrictions as are applicable to the shares of restricted stock on which they
were distributed.

      If the outstanding shares of the Common Stock shall be changed into or
exchangeable for a different number or kind of shares of stock or other
securities of the Company or another corporation, or cash or other property,
whether through reorganization, reclassification, recapitalization, stock
split-up, combination of shares, merger or consolidation, then there shall be
substituted for each share of the Common Stock set forth in Section 3, for each
share of the Common Stock subject to any then outstanding stock option, and for
each share of the Common Stock which may be issued under the Plan but which is
not then subject to any outstanding stock option or restricted stock award, the
number and kind of shares of stock or other securities (and in the case of
outstanding options, the cash or other property) into which each outstanding
share of the Common Stock shall be so changed or for which each such share shall
be exchangeable. Unless otherwise determined by the Committee in its discretion,
any such stock or securities, as well as any cash or other property, into or for
which any restricted stock held in escrow shall be changed or exchangeable in
any such transaction shall also be held by the Company in escrow and shall be
subject to the same restrictions as are applicable to the restricted stock in
respect of which such stock, securities, cash or other property was issued or
distributed.

      In case of any adjustment or substitution as provided for in this Section
6, the aggregate option price for all shares subject to each then outstanding
stock option prior to such adjustment or substitution shall be the aggregate
option price for all shares of stock or other securities (including any
fraction) to which such shares shall have been adjusted or which shall have been
substituted for such shares. Any new option price per share shall be carried to
at least three decimal places with the last decimal place rounded upwards to the
nearest whole number.

      No adjustment or substitution provided for in this Section 6 shall require
the Company to issue or sell a fraction of a share or other security.
Accordingly, all fractional shares or other securities which result from any
such adjustment or substitution shall be eliminated and not carried forward to
any subsequent adjustment or substitution.


                                      -7-


                                    SECTION 7
          Effect of the Plan on the Rights of Company and Shareholders

      Nothing in the Plan, in any stock option or restricted stock award granted
under the Plan, or in any stock option or restricted stock agreement shall
confer any right to any person to continue as a Director of the Company or
interfere in any way with the rights of the shareholders of the Company or the
Board of Directors to elect and remove Directors.

                                    SECTION 8
                            Amendment and Termination

      The right to amend the Plan at any time and from time to time and the
right to terminate the Plan at any time are hereby specifically reserved to the
Board; provided always that no such termination shall terminate any outstanding
stock options granted under the Plan; and provided further that no amendment of
the Plan shall (a) be made without shareholder approval if shareholder approval
of the amendment is at the time required for stock options under the Plan to
qualify for the exemption from Section 16(b) of the Exchange Act provided by
Rule 16b-3 or by the rules of the NASDAQ National Market System or any stock
exchange on which the Common Stock may then be listed or (b) otherwise amend the
Plan in any manner that would cause stock options or restricted stock awards
under the Plan not to qualify for the exemption provided by Rule 16b-3. No
amendment or termination of the Plan shall, without the written consent of the
holder of a stock option or restricted stock award theretofore awarded under the
Plan, adversely affect the rights of such holder with respect thereto.

      Notwithstanding anything contained in the preceding paragraph or any other
provision of the Plan or any stock option or restricted stock agreement, the
Board shall have the power to amend the Plan in any manner deemed necessary or
advisable for stock options and restricted stock awards granted under the Plan
to qualify for the exemption provided by Rule 16b-3 (or any successor rule
relating to exemption from Section 16(b) of the Exchange Act), and any such
amendment shall, to the extent deemed necessary or advisable by the Board, be
applicable to any outstanding stock options and restricted stock awards
theretofore granted under the Plan notwithstanding any contrary provisions
contained in any stock option or restricted stock agreement. In the event of any
such amendment to the Plan, the holder of any stock option or restricted stock
award outstanding under the Plan shall, upon request of the Committee and as a
condition to the exercisability of such option or the retention of such
restricted stock award, execute a conforming amendment in the form prescribed by
the Committee to the stock option agreement or the restricted stock agreement,
as the case may be, within such reasonable time as the Committee shall specify
in such request.

                                    SECTION 9
                       Effective Date and Duration of Plan

      The effective date and date of adoption of the Plan shall be December 17,
1990, the date of adoption of the Plan by the Board, provided that on or prior
to December 31, 1991 such adoption of the Plan by the Board is approved by the
affirmative vote of the holders of at least a majority of the outstanding shares
of voting stock of the Company represented in person or by


                                      -8-


proxy at a duly called and convened meeting of such holders. Notwithstanding any
other provision contained in the Plan, no stock option granted under the Plan
may be exercised until after such shareholder approval.

                                   SECTION 10
                                Change in Control

      Notwithstanding any other provision of the Plan to the contrary,
immediately prior to any Change in Control of the Company (as defined in Section
11), all stock options which are then outstanding hereunder shall become fully
vested and exercisable, and all restrictions with respect to shares of
restricted stock awarded hereunder shall lapse, and such shares shall be fully
vested and nonforfeitable. As used in the immediately preceding sentence,
"immediately prior" to the Change in Control shall mean sufficiently in advance
of the Change in Control to permit the grantee to take all steps reasonably
necessary to exercise the option fully and to deal with the shares purchased
under the option and the restricted stock released from restriction so that
those shares may be treated in the same manner in connection with the Change in
Control as the shares of Common Stock of other shareholders.

                                   SECTION 11
                                   Definitions

      In addition to terms defined elsewhere herein, as used in the Plan:

      Beneficial Owner shall have the meaning set forth in Rule 13d-3 under the
      ----------------
Exchange Act.

      A Change in Control shall be deemed to have occurred if the event set
        -----------------

      Beneficial Owner (as defined in this Section 11), directly or indirectly,
      of securities of the Company (not including in the securities beneficially
      owned by such Person any securities acquired directly from the Company or
      its Affiliates (which term shall have the meaning set forth in Rule 12b-2
      promulgated under Section 12 of the Exchange Act, as defined in this
      Section 11)) representing thirty percent (30%) or more of the combined
      voting power of the Company's then outstanding securities, excluding any
      Person who becomes such a Beneficial Owner in connection with a
      transaction described in clause (I) of paragraph (III) below; or

            (II) the following individuals cease for any reason to constitute a
      majority of the number of Directors then serving: individuals who, on May
      5, 1998, constitute the Board and any new Director (other than a Director
      whose initial assumption of office is in connection with an actual or
      threatened election contest, including but not limited to a consent
      solicitation, relating to the election of Directors of the Company) whose
      appointment or election by the Board or nomination for election by the
      Company's shareholders was approved or recommended by a vote of at least
      two-thirds (2/3) of the Directors then still in office who either were
      Directors on May 5, 1998 or whose


                                      -9-


      appointment, election or nomination for election was previously so
      approved or recommended; or

            (III) there is consummated a merger or consolidation of the Company
      or any direct or indirect subsidiary of the Company with any other
      corporation, other than (I) a merger or consolidation which would result
      in the voting securities of the Company outstanding immediately prior to
      such merger or consolidation continuing to represent (either by remaining
      outstanding or by being converted into voting securities of the surviving
      entity or any parent thereof), in combination with the ownership of any
      trustee or other fiduciary holding securities under an employee benefit
      plan of the Company or any subsidiary of the Company, at least fifty-one
      percent (51%) of the combined voting power of the securities of the
      Company or such surviving entity or any parent thereof outstanding
      immediately after such merger or consolidation, or (ii) a merger or
      consolidation effected to implement a recapitalization of the Company (or
      similar transaction) in which no Person is or becomes the Beneficial
      Owner, directly or indirectly, of securities of the Company representing
      thirty percent (30%) or more of the combined voting power of the Company's
      then outstanding securities; or

            (IV) the shareholders of the Company approve a plan of complete
      liquidation or dissolution of the Company or there is consummated an
      agreement for the sale or disposition by the Company of all or
      substantially all of the Company's assets, other than a sale or
      disposition by the Company of all or substantially all of the Company's
      assets to an entity, at least fifty-one percent (51%) of the combined
      voting power of the voting securities of which are owned by shareholders
      of the Company in substantially the same proportions as their ownership of
      the Company immediately prior to such sale.

      Notwithstanding the foregoing, a Change in Control shall not be deemed to
have occurred by virtue of the consummation of any transaction or series of
integrated transactions immediately following which the record holders of the
common stock of the Company immediately prior to such transaction or series of
transactions continue to have substantially the same proportionate ownership in
an entity which owns all or substantially all of the assets of the Company
immediately following such transaction or series of transactions.

      Disability shall mean that the Director is disabled within the meaning of
      ----------
Section 22(e)(3) of the Code. Whether a grantee is so disabled shall be
determined, in its discretion, by the Committee, and any such determination by
the Committee shall be final and binding.

      Exchange Act shall mean the Securities and Exchange Act of 1934, as
      ------------
amended from time to time.

      Fair Market Value of the Common Stock shall be the mean between the
      -----------------
following prices, as applicable, for the date as of which Fair Market Value is
to be determined as quoted in The Wall Street Journal (or in such other reliable
                              -----------------------
publication as the Committee, in its discretion, may determine to rely upon):
(a) if the Common Stock is listed on the New York Stock Exchange, the highest
and lowest sales prices per share of the Common Stock as quoted in the
NYSE-Composite Transactions listing for such date, (b) if the Common Stock is
not listed on such exchange, the highest and lowest sales prices per share of
Common Stock for such date on


                                      -10-


(or on any composite index including) the principal United States securities
exchange registered under the Exchange Act on which the Common Stock is listed,
or (c) if the Common Stock is not listed on any such exchange, the highest and
lowest sales prices per share of the Common Stock for such date on the National
Association of Securities Dealers Automated Quotations System or any successor
system then in use ("NASDAQ"). If there are no such sale price quotations for
the date as of which Fair Market Value is to be determined but there are such
sale price quotations within a reasonable period both before and after such
date, then Fair Market Value shall be determined by taking a weighted average of
the means between the highest and lowest sales prices per share of the Common
Stock as so quoted on the nearest date before and the nearest date after the
date as of which Fair Market Value is to be determined. The average should be
weighted inversely by the respective numbers of trading days between the selling
dates and the date as of which Fair Market Value is to be determined. If there
are no such sale price quotations on or within a reasonable period both before
and after the date as of which Fair Market Value is to be determined, then Fair
Market Value of the Common Stock shall be the mean between the bona fide bid and
asked prices per share of Common Stock as so quoted for such date on NASDAQ, or
if none, the weighted average of the means between such bona fide bid and asked
prices on the nearest trading date before and the nearest trading date after the
date as of which Fair Market Value is to be determined, if both such dates are
within a reasonable period. The average is to be determined in the manner
described above in this paragraph. If the Fair Market Value of the Common Stock
cannot be determined on the basis previously set forth in this paragraph for the
date as of which Fair Market Value is to be determined, the Committee shall in
good faith determine the Fair Market Value of the Common Stock on such date.
Fair Market Value shall be determined without regard to any restriction other
than a restriction which, by its terms, will never lapse.

      Person shall have the meaning given in Section 3(a)(9) of the Exchange
      ------
Act, as modified and used in Sections 13(d) and 14(d) thereof, except that such
term shall not include (I) the Company or any of its subsidiaries, (ii) a
trustee or other fiduciary holding securities under an employee benefit plan of
the Company or any of its Affiliates, (iii) an underwriter temporarily holding
securities pursuant to an offering of such securities, or (iv) a corporation
owned, directly or indirectly, by the shareholders of the Company in
substantially the same proportions as their ownership of stock of the Company,
or (v) any individual or entity [including the trustees (in such capacity) of
any such entity which is a trust] which is, directly or indirectly, the
Beneficial Owner of securities of the Company representing five percent (5%) or
more of the combined voting power of the Company's then outstanding securities
immediately before the date hereof or any Affiliate of any such individual or
entity, including, for purposes of this Plan, any of the following: (A) any
trust (including the trustees thereof in such capacity) established by or for
the benefit of any such individual; (B) any charitable foundation (whether a
trust or a corporation, including the trustees or directors thereof in such
capacity) established by any such individual; (C) any spouse of any such
individual; (D) the ancestors (and spouses) and lineal descendants (and spouses)
of such individual and such spouse; (E) the brothers and sisters (whether by the
whole or half blood or by adoption)of either such individual or such spouse; or
(F) the lineal descendants (and their spouses) of such brothers and sisters.

      Retirement shall mean a termination of a Director's service on the Board
      ----------
on or after the date that (1) the Director has completed least 5 years of
service as a Director and (2) the Director's combined age and service as a
Director satisfy the "Rule of 75." The "Rule of 75"


                                      -11-


shall be satisfied when the sum of the Director's age (measured in full and
partial years, in increments of one-twelfth (1/12) year) and the Director's
years of service as a Director (measured in full and partial years, in
increments of one-twelfth (1/12) year) equals or exceeds 75.


                                      -12-


                                                                 EXHIBIT (10)(g)

equals or exceeds 70.

                                       3


Section 3 - Eligibility
- -----------------------

     Those members of management who are eligible to participate in the
Executive Insurance Program shall be the Chief Executive Officer of the Company
and such other key members of senior management as shall be designated from time
to time by the Chief Executive Officer of the Company and approved for
participation by the Board of Directors.

Section 4 - Amount and Effective Date of Coverage
- -------------------------------------------------

     The initial amount of life insurance coverage provided under the Plan to
those selected for participation as of the effective date of the Plan shall be
as described in the "Table of Insurance Amounts" attached hereto.  The amount of
life insurance provided to executives who are selected for participation after
the effective date of the Plan shall be in an amount determined by the Chief
Executive Officer and approved by the Board at the time of their selection.

     The effective date of insurance coverage hereunder shall be the later of
the date of the employee's selection for participation herein or acceptance by
the Insurer as a standard risk.  The cancellation of a Participant's group term
life insurance in excess of $50,000, and his actual participation in this Plan
shall be conditioned upon his insurability in a standard risk category for the
benefit to be provided herein or, if not insurable in a standard risk category,
the acceptance by the Company of the non-standard risk category proposed by the
Insurer.

     The Board reserves the right to change the amount of insurance on the life
of any Participant from time to time, and any such change in the level of
insurance shall be effective as of the later of the first day of the month
coincident with or next following the effective date of the change or the date
of acceptance by the Insurer of the new insurance amount at standard rates, or
acceptance by the Company of an offer of insurance made by the Insurer at non-
standard rates; provided, however, that, from and after the first date on which
the combined age and service of any Participant (whether a Retired Participant
or an active Participant) satisfy the Rule of 70 (as the satisfaction of such
Rule is described in the definition of Retired Participant which appears in
Section 2 hereof) or will have satisfied the Rule of 70 upon an assumed
immediate termination of employment (as the requirements for satisfaction of
such Rule may have been modified by any written Severance Agreement between the
Company and such Participant), the amount of insurance on the life of such
Participant (sometimes referred to in this Plan as the "Insurance Amount")
cannot be decreased.

Section 5 - Payment for Coverage
- --------------------------------

     The cost of the applicable amount of life insurance on the life of the
Participant shall be paid when due by the Company.  The Company shall annually
furnish each Participant with a statement of imputed income reportable by the
Participant for income tax purposes as a result of the payment.

                                       4


Section 6 - Payment of Proceeds Upon Death While Employed
- ---------------------------------------------------------

     In the event of the death of the Participant while employed by the Company,
the gross death benefit payable under the Policy shall be split between the
Company and the Participant's Beneficiary.  The Beneficiary shall receive an
amount equal to the Insurance Amount and the Company shall receive the
difference between the gross Death Benefit and the Insurance Amount.  The
amounts payable to the Company and the Beneficiary shall be paid directly to
each payee by the Insurer directly from the Insurer.

Section 7 - Options Upon Retirement of a Participant
- ----------------------------------------------------

     Subject to Section 8 hereof, at any time prior to the year in which a
Participant becomes a Retired Participant, he shall have the right to make an
irrevocable election in writing of one of the following three options with
respect to his Insurance Amount.  If a Participant shall fail to make such an
election, he shall be deemed to have elected the supplemental retirement benefit
payments described in this Section 7 as Option 3.

     (1)    Maintain the Existing Arrangement.  Under this option the Executive
            ----------------------------------
Insurance Program would remain as it existed prior to the Participant's
retirement.  For federal income tax purposes, a Retired Participant will be
deemed to have received imputed income, but the Death Benefit received by the
Participant's Beneficiary will not be subject to federal income tax.

     (2)    Company-Paid Post-Retirement Death Benefit.  Alternatively, the
            ------------------------------------------
Participant can elect not to continue the Executive Insurance Program, but in
lieu thereof, can elect a non-insured post-retirement death benefit equal to the
Insurance Amount in effect at the date of the Participant's retirement.  Under
this Option there is no imputed income for tax purposes to the Retired
Participant but the Death Benefit paid to the Participant's Beneficiary by the
Company will be subject to federal income tax when received.

     (3)    Supplemental Retirement Benefits.  Rather than a continuation of the
            --------------------------------
Death Benefit described in either Option 1 or Option 2 above, a Participant can
elect to receive a series of supplemental retirement payments which, in the
aggregate, equal three-quarters (75%) of the pre-retirement Insurance Amount
except that for a Participant who will receive supplemental retirement benefits
under this Section 7(3) for the first time on or after January 1, 2001, such
Participant can elect to receive a series of supplemental retirement payments
which, in the aggregate, equal one hundred (100%) percent of the pre-retirement
Insurance Amount.  Payment of the supplemental retirement benefits shall be made
in a series of approximately equal semi- monthly payments over a period of 15
years.  Payment of such semi-monthly payments to the Retired Participant shall
commence no later than sixty days after the Retired Participant's termination of
employment with the Company.

     The Supplemental Retirement Benefit Option may be elected by a Participant
at any time on or after August 1, 1991.  It shall be available to any
Participant who retires on or after that date as well as to any previously
Retired Participant who had previously elected either Option 1 or Option 2.  If
the supplemental retirement payments of Option 3 are elected, and in the event
of

                                       5


the death of the Retired Participant prior to the completion of the 15-year
payment period, the then unpaid installments shall continue to be paid to the
Retired Participant's Beneficiary or, at the discretion of the Board, may be
commuted and paid to such Beneficiary in a single sum as soon as may be
practicable after the Board's decision to make such a single sum payment.

Section 8 - Effect of a Change in Control
- -----------------------------------------

     Notwithstanding any other provision of this Plan, if a Participant's
termination of employment occurs on, or within the three-year period immediately
following, a Change in Control and the Participant thereupon becomes a Retired
Participant within the meaning of Section 2 hereof (the determination of such
Retired Participant status taking into account any relevant provision in any
written Severance Agreement the Participant may have with the Company), then,
not later than the fifth (5th) business day following such termination, the
Company shall pay the Retired Participant a lump sum amount equal to the present
value of the series of supplemental retirement payments described as Option 3 in
Section 7 hereof to which the Retired Participant would otherwise be entitled if
the Retired Participant had elected Option 3.  The Company's payment of such
lump sum shall be in lieu of making payment to the Retired Participant in
accordance with any option described in Section 7 hereof.  For purposes of this
Section 8, such present value shall be determined using a discount rate equal to
120% of the applicable rate provided in section 1274(b)(2)(B) of the Internal
Revenue Code of 1986, as amended from time to time.

Section 9 - Administration, Amendment, Termination
- --------------------------------------------------

     The Board, or its delegate, shall be the "Administrator" of this Plan, and
shall have full power and authority to interpret, construe and administer the
same.  Any such interpretation and construction shall be final and binding upon
any and all parties in interest.  In addition, the Board shall have the right to
amend this Plan from time to time, and to terminate it at any time..
Notwithstanding the foregoing provisions of this Section 9, no amendment or
termination of this Plan by the Board and no act (or failure to act) by the
Board (or its delegate) as Administrator shall affect detrimentally the rights
under the Plan of any Retired Participant or of any active Participant whose
combined age and service have satisfied the Rule of 70 (as the satisfaction of
such Rule is described in the definition of Retired Participant which appears in
Section 2 hereof) or will have satisfied the Rule of 70 upon an assumed
immediate termination of employment (as the requirements for satisfaction of
such Rule may have been modified by any written Severance Agreement between the
Company and such Participant).

Section 10 - Miscellaneous Matters
- ----------------------------------

     (a)     No Right to Assets.  No Participant, Beneficiary or other person or
             ------------------
entity claiming entitlement to any benefit from or through such person shall
have any right to or title in any policy or any other asset obtained by the
Company for the purpose of funding the benefits provided hereunder except as
otherwise expressly provided herein.

                                       6


     (b)     Alienation.  Except with respect to the designation of a
             ----------
Beneficiary to be the recipient of any death benefits hereunder, or the
assignment of the incidents of ownership of any death benefits hereunder, the
interest of Participants and their Beneficiaries under the Plan are not in any
way subject to their debts or other obligations and may not be voluntarily or
involuntarily sold, transferred, assigned, alienated or encumbered, and any
attempt to do so shall be void

     (c)     Construction.     The Plan shall be construed and administered
             ------------
according to the laws of the Commonwealth of Pennsylvania and any 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 apply, and whenever any
words are used 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.  Headings
of Sections of this instrument are inserted for convenience of reference only
and as such they constitute no part of this Plan and are not to be considered in
the construction hereof.

     (d)     Limitation of Benefit.  All benefits hereunder except those
             ---------------------
described in Section 8 and Options 2 and 3 of Section 7 shall be payable solely
by the Insurer(s) under the Policies issued hereunder, and the Company does not
assume any liability or responsibility therefor or guarantee such benefits.  The
liability and responsibility of the Company are strictly limited to the
provisions of this Plan.

Management's Discussion and Analysis

Forward-looking Statements

      This report contains "forward-looking statements" within the meaning of
the Private Securities Litigation Reform Act of 1995. Such forward-looking
statements may include, without limitation, statements regarding expectations
for future product introductions, cost reduction and restructuring plans,
liquidity, sales and earnings, and market risk. Actual results may differ from
expectations contained in such forward-looking statements and can be affected by
any number of factors, many of which are outside of management's direct control.
Among the factors that could cause such differences are the effects of cost
reduction efforts, new product introductions, market and operating conditions
affecting specialty chemical customers, availability of critical materials and
components, the economic environment, and interest and currency exchange rates.

Results of Operations

      Corporate initiatives - During the past year, MSA made significant
progress in improving its competitive position and profitability through new
product introductions, targeted acquisitions in focused product and geographic
markets, and continuing cost reduction programs. These efforts are expected to
continue in 2001 and beyond.

      In 2000, MSA strengthened its product offerings and commitment to the fire
service market in two important ways - the introduction of the Evolution line of
Thermal Imaging Cameras and the addition of CairnsHelmets, the most respected
and established line of firefighter head protection. Since the mid-nineties, MSA
has recognized the dramatic market potential of thermal imaging camera
technology in protecting lives and assisting firefighters in the line of duty.
During the first quarter of 2000, the company's commitment to the practical
application of this technology was demonstrated by the acquisition of ISI Group,
Inc. (ISIG), an established manufacturer of infrared cameras, and the mid-year
introduction of the MSA-designed and manufactured Evolution line of cameras. In
August, MSA acquired CairnsHelmets of Clifton, New Jersey, the best known and
respected supplier of firefighter head protection in North America.

      On February 2, 2001, MSA acquired Surety Manufacturing and Testing, Ltd.
in Canada. Surety is a leading provider of fall protection equipment and rescue
systems to railway, construction, and utility markets. The acquisition
complements the existing line of MSA Rose fall protection products and services.
In addition, the Surety line of rescue and retrieval systems further enhances
MSA product offerings to the fire service market.

      Current year results in North America benefited from workforce reduction
and voluntary retirement incentive programs that were completed in 1999. Further
activities are underway in 2001 to more closely integrate the company's sales
and marketing strategy throughout North America and to streamline operations,
particularly in Canada. The company remains committed to the
previously-announced plan to consolidate office space in Pittsburgh as a means
of further reducing operating costs and improving communications and
productivity.

      In Europe, the company is making organizational changes that are expected
to dramatically improve profitability by reducing operating costs, improving
manufacturing efficiencies, and providing an integrated marketing and
distribution approach. Significant European reorganization efforts include
centralized customer service, product line management, and inventory planning
and control. Country-specific reorganization is also underway in Britain and
Germany, including workforce reductions and sale of excess facilities.

      In South Africa, the company completed its reorganization and facilities
consolidation plan following the 1999 acquisition of Campbell Gardwel, a South
African maker of personal protective equipment. MSA is now positioned as the
largest safety products supplier on the African continent, with strength in both
mining and industrial markets.

      During the year a dedicated team made significant progress in advancing
the company's e-business capabilities. Initial applications that facilitate
business relationships with the company's North American distributor/partners
are expected to be operational in the first half of 2001, including an on-line
catalog and internet-enabled inventory, order, and account status query
capabilities.

      Supply-chain management presents MSA with major opportunities for
improving inventory management, manufacturing efficiencies, and customer
service. In 2000, the company established a team that is focused on improving
all aspects of supply chain management.

      2000 versus 1999 - Sales for 2000 were $500.4 million, an increase of $2.5
million, or less than 1%, from $497.9 million in 1999. Local currency sales
growth of 5% was partially offset by negative exchange rate movements when
stated in U.S. dollars.

      Sales by North American operations were $327.8 million in 2000, an
increase of $12.7 million, or 4%, from $315.1 million in 1999. Higher sales in
2000 reflect new product offerings and strong shipments of core safety products
to the fire service, industrial and construction markets. Shipments of
self-contained breathing apparatus for firefighters, gas masks for defense
preparedness, and helmets for industrial and construction worker head-protection
all improved significantly during the year. Sales were also strengthened by the
third quarter 2000 introductions of the Evolution series of thermal imaging
cameras and the CairnsHelmets line of firefighter head protection. The company
expects continued sales growth with the inclusion of a full year of sales for
these products in 2001. Portable instrument sales were also higher in 2000,
reflecting the late-1999 introduction of the improved Passport FiveStar Alarm
multigas detector. Specialty chemical sales in 2000 were 8% lower than in the
prior year, but rebounded sharply in the fourth quarter. Short-term specialty
chemical sales levels are highly dependent on the performance of a limited
number of large pharmaceutical and chemical company customers. The company
believes that lower specialty chemical sales in the second half of 1999 and the
first three quarters of 2000 were largely due to a number of special situations
with individual customer's drug development, production and marketing
activities. Continued recovery in specialty chemical sales is expected in 2001.

      Sales by European operations were $99.1 million in 2000, a decrease of
$14.3 million, or 13%, from $113.4 million in 1999. However, in local currency,
sales in Europe were flat year-to-year. Sales growth in Eastern European markets
was offset by mixed, but somewhat lower sales in Western European affiliates.

14 | 2000 MSA Annual Report


      Sales by MSA's other international operations were $73.2 million in 2000
compared to $68.0 million in 1999, an increase of $5.2 million, or 8%. A 14%
improvement in local currency sales was partially offset by unfavorable currency
translation effects when stated in U.S. dollars. Sales growth in South America
was particularly strong on improved economic conditions in the region. Notable
growth also occurred in Africa and China reflecting expanding operations in
those areas.

      Gross profit for 2000 was $187.1 million, an increase of $7.4 million, or
4%, from $179.7 million in 1999. An increase in the ratio of gross profit to
sales to 37.4% in 2000 from 36.1% in 1999 is the primary reason for higher gross
profit in 2000. Higher sales accounts for approximately $1.0 million of the
gross profit improvement.

      Research and development expenses were largely unchanged in 2000 at $17.2
million, compared to $17.1 million in 1999. These expenses relate primarily to
safety and health equipment research and development activities in the U.S. and
Germany.

      Depreciation, selling and administrative expenses decreased $3.8 million
to $149.0 million in 2000, and decreased as a percent of sales to 29.8% in 2000
compared to 30.7% in 1999. The decrease follows a similar decrease in 1999 and
is the result of cost saving restructuring initiatives in North America and
Europe. Depreciation, selling and administrative expenses at other international
operations were slightly higher than in 1999.

      Cost of products sold and selling, general and administrative expenses
include net periodic pension benefit costs and credits. As described in note 12,
pension credits, combined with pension costs, resulted in net pension credits of
$14.9 million in 2000 and $10.2 million in 1999. Net pension credits in 2000
included credits of $2.4 million for settlement and curtailment gains in Canada
and Britain. In 1999 net pension credits included a net gain of $2.8 million
resulting from the termination benefit costs and settlement gains associated
with a voluntary retirement incentive program in the U.S. Future net pension
credits can be volatile depending on the future market performance of plan
assets, changes in actuarial assumptions regarding discount rates and return on
plan assets, changes in the amortization levels of actuarial gains and losses,
plan amendments affecting benefit payout levels, and profile changes in the
participant populations. Changes in any of these factors could cause net pension
credits to change. To the extent net pension credits decline in the future,
income would be adversely affected.

      Interest expense in 2000 was $4.5 million compared to $4.3 million in
1999.

      Currency exchange gains were $444,000 in 2000 compared to $694,000 in
1999. The most significant gains from currency valuation changes in 2000
occurred in North America.

      Restructuring charges in 2000 were $2.4 million compared to $4.0 million
in 1999. The charges in 2000 relate primarily to severance and early retirement
costs associated with workforce reductions in Britain, Germany and Canada. The
1999 charges were principally for severance costs in Germany.

      Other income, for which further information is included in note 4, was
$2.5 million in 2000 compared to $3.8 million in 1999. Other income in 2000
included a discount of $2.7 million on the sale of trade accounts receivable
under the securitization agreement, which is more fully-described in note 15.
Because the accounts receivable securitization arrangement commenced in November
1999, the comparable loss in the prior year was only $300,000.

      The effective income tax rate, for which further information is included
in note 8, was 31.8% in 2000 and 29.6% in 1999. The effective rate in both years
was lower than the U.S. statutory income tax rate primarily due to operating
losses in Germany and adjustments to prior years' taxes in the U.S., mainly due
to foreign sales corporation tax benefits.

      As further described in note 16, during 1999 the company changed the
reporting periods of a number of international affiliates, including Germany
which is the company's largest international affiliate. The effect of this
change, which represents the after-tax results of these affiliates for December
1999, is reported as a change in accounting principle. The December 1999 net
loss included severance costs related to ongoing workforce reductions in
Germany.

      Net income for 2000 was $23.2 million, an increase of $8.1 million, or
54%, over 1999 net income of $15.1 million. Basic earnings per share of common
stock improved to $1.89 in 2000 compared to $1.16 in 1999. Earnings per share
benefited from net treasury share repurchases that reduced average shares
outstanding by 5% in 2000.

      1999 versus 1998 - Sales for 1999 were $497.9 million, a decrease of $2.3
million, or less than 1%, from $500.2 million in 1998. Sales in 1998 included
the HAZCO Services, Inc. and Baseline Industries, Inc. business units until they
were divested on June 30, 1998. Sales of ongoing operations improved $19.3
million in 1999, but were partially offset by the negative currency translation
effect of the strong U.S. dollar on international affiliate sales.

      Sales by North American operations were $315.1 million in 1999, an
increase of $3.6 million, or 1%, from $311.5 million in 1998. North American
sales in 1998 included HAZCO Services, Inc. and Baseline Industries, Inc.,
through mid-year. The divestitures resulted in approximately $13.6 million less
sales in 1999 compared to 1998. The improvement in North American sales from
ongoing businesses reflected strong growth in safety products sales, partially
offset by lower shipments of specialty chemicals. Sales of self-contained
breathing apparatus and thermal imaging cameras to fire service markets in the
U.S. and Canada were particularly strong in 1999. Lower specialty chemical sales
in 1999 reflect a number of special situations with individual customers during
the second half of the year.

      Sales by European operations, stated in U.S. dollars, were $113.4 million
in 1999, a decrease of $8.0 million, or 7%, from $121.4 million in 1998. The
decrease reflects a slight decline in local currency sales and negative currency
translation effects when stated in U.S. dollars. Flat or somewhat improved local
currency sales in most European countries were partially offset by lower sales
in Britain.

      Sales by MSA's other international operations were $68.0 million in 1999
compared to $64.1 million in 1998, an increase of $3.9 million, or 6%.
Significant improvements in local currency sales in most countries were
partially offset by unfavorable currency translation effects when stated in U.S.
dollars. Local currency sales increased in 1999 at most operations, but were


                                                     15 | 2000 MSA Annual Report


Management's Discussion and Analysis

particularly strong in Africa, which benefited from the second quarter
acquisition of Campbell Gardwel. Sales in South America were somewhat lower in
1999 due to continuing economic difficulties in Peru and Chile.

      Gross profit for 1999 was $179.7 million, a decrease of $4.7 million, or
3%, from $184.4 million in 1998. Approximately $1.0 million of the decrease was
volume related. The remainder of the decrease in gross profit dollars was due to
a small decline in the ratio of gross profit to sales to 36.1% in 1999 compared
to 36.9% in 1998.

      Research and development expenses were largely unchanged in 1999 at $17.1
million, compared to $17.4 million in 1998. These expenses relate primarily to
safety and health equipment research and development activities in the U.S. and
Germany.

      Depreciation, selling and administrative expenses decreased $4.9 million
to $152.8 million in 1999 compared to $157.7 million in 1998, and decreased as a
percent of sales to 30.7% in 1999 compared to 31.5% in 1998. The decrease
reflects cost savings resulting from restructuring initiatives in the U.S. and
the mid-1998 divestitures of HAZCO Services, Inc. and Baseline Industries, Inc.
Depreciation, selling and administrative expenses at international operations
were slightly higher than in 1998.

      Cost of products sold and selling, general and administrative expenses
include net periodic pension benefit costs and credits. As described in note 12,
pension credits, combined with pension costs, resulted in net pension credits of
$10.2 million in 1999 and $10.3 million in 1998. Net pension credits in 1999 and
1998 included settlement gains, net of termination benefit costs, of $2.8
million and $4.0 million, respectively.

      Currency exchange gains were $694,000 in 1999, compared to losses of
$315,000 in 1998. The most significant gains from currency valuation changes in
1999 occurred in Latin America.

      Restructuring charges in 1999 were $4.0 million compared to $1.0 million
in 1998. The charges in both years relate primarily to severance and early
retirement costs associated with workforce reductions in Germany.

      Other income, for which further information is included in note 4, was
$3.8 million in 1999 compared to $6.0 million in 1998. Other income for 1999
included pre-tax gains of $2.2 million on sales of real estate. Other income for
1998 included $2.8 million pre-tax gains related to the divestitures of the
HAZCO Services, Inc. and Baseline Industries, Inc. affiliates. The operating
results of these two affiliates were not material to the consolidated financial
statements during the year ended December 31, 1998.

      The effective income tax rate, for which further information is included
in note 8, was 29.6% in 1999 and 35.2% in 1998. The lower effective rate in 1999
reflects tax benefits on international operating losses, primarily in Germany,
and adjustments to prior years' taxes in the U.S., mainly due to foreign sales
corporation tax benefits.

      As further described in note 16, during 1999 the company changed the
reporting periods of a number of international affiliates, including Germany
which is the company's largest affiliate. The change in reporting period reduced
1999 net income by $1.2 million and earnings per share of common stock by $0.09,
representing the after-tax results of the affected affiliates for the one month
period ended December 31, 1999. This net loss included severance costs related
to ongoing workforce reductions in Germany combined with the results of low
December operating activity in the units affected.

      Net income for 1999 was $15.1 million compared to $18.3 million in 1998.
Basic earnings per share of common stock declined in 1999 to $1.16, compared to
$1.37 in 1998. Earnings per share benefited from share repurchases that reduced
average shares outstanding by 2% in 1999.

Liquidity and Financial Condition

      Cash and cash equivalents increased $9.4 million during 2000, compared to
a decrease of $6.9 million in 1999. The company's principal source of financing
capital expenditures and internal growth is cash flow from operations.
Operations provided cash of $52.3 million in 2000 compared to providing $39.4
million in 1999. The most significant reasons for improved operating cash flow
were higher earnings and reduced inventories. Cash provided by operations in
1999 was $18.7 million higher than in 1998.

      Investing activities used cash of $46.2 million in 2000 compared to $29.6
million in 1999. The increased use of cash for investing activities in 2000 was
for the acquisitions of CairnsHelmets and ISI Group, Inc. In 1999 acquisitions
and other investing included $2.6 million related to the acquisition of Campbell
Gardwel in South Africa and $2.7 million for development costs at the Cranberry
Woods office park. Cash flow for investing activities in 1998 benefited from net
proceeds of $22.9 million received on the sales of HAZCO Services, Inc. and
Baseline Industries, Inc. Capital expenditures totaled $19.4 million in 2000,
$26.2 million in 1999, and $34.3 million in 1998. Both 1999 and 1998 included
increased expenditures for information systems and manufacturing facility
improvements associated with U.S. restructuring activities. In the past five
years, approximately $137 million has been spent on new facilities, equipment,
and information systems.

      Financing activities provided cash of $4.1 million in 2000 compared to
using $15.4 million in 1999. During 2000 the company issued $40 million of
private placement debt to finance acquisitions and common stock repurchases. The
additional use of cash in 1999 reflects reductions in short-term borrowings
during the year. Dividends paid on common stock during 2000 (the 83rd
consecutive year of dividend payment) were 47 cents per share, up from 44 cents
per share in both 1999 and 1998. Cash dividends are paid at a conservative
percentage of income. During 2000 the company repurchased 2.2 million shares of
common stock, including 2.1 million shares from the family of a co-founder, for
$54.9 million. Approximately 1.1 million shares of common stock held in treasury
were sold to the MSA pension plan in 2000 for $27.0 million. As of December 31,
2000, an additional 89,705 shares may be repurchased under current
authorizations.

      Short term debt decreased $2.7 million during 2000 to $1.3 million. The
average amount of short term debt outstanding during 2000 and 1999 was $5.6
million and $38.9 million, respectively. Credit available at year-end with
financial institutions was the U.S. dollar equivalent of $21.4 million, of which
$19.6 million was unused.

      Long-term debt, including the current portion, increased $40.2 million
during 2000 to $77.1 million, or 25.4% of total capital. Total capital is
defined as long-term debt plus the current


16 | 2000 MSA Annual Report


portion of long-term debt and shareholders' equity. The increase is due to the
issuance of $40 million in fixed rate senior notes payable in installments
through 2012. Proceeds of the notes were used for acquisitions and common stock
repurchases.

      Trade receivables decreased $11.8 million to $47.1 million at December 31,
2000. As more-fully described in note 15, the decrease reflects the sale of
accounts receivable under the securitization facility. Trade receivables
expressed in number of days' sales outstanding was 34 days at December 31, 2000,
compared to 43 days at the end of 1999. Other receivables were $30.5 million at
December 31, 2000 and $22.7 million at December 31, 1999, representing the
company's retained interest in securitized receivables. Inventories decreased
$9.4 million to $72.7 million at December 31, 2000. Inventory measured against
sales turned 6.9 times in 2000 and 6.1 times in 1999. The working capital ratio
was 2.3 to 1 at the end of 2000 and 2.5 to 1 at the end of 1999.

      The company's financial position remains strong and is expected to provide
adequate capital resources for operations, capital expansion and dividends to
shareholders.

Cumulative Translation Adjustments

      The year-end position of the U.S. dollar relative to international
currencies resulted in translation losses of $5.9 million being charged to the
cumulative translation adjustments shareholders' equity account in 2000,
compared to losses of $5.1 million in 1999 and $3.6 million in 1998. Translation
losses in 2000 occurred primarily in Australia, South Africa, Britain, Canada,
and Germany. Translation losses in 1999 occurred primarily in Brazil, Germany
and Italy. Significant 1998 translation losses occurred in Germany, Canada and
Australia.

Financial Instrument Market Risk

      Market risk represents the risk of adverse changes in the value of a
financial instrument caused by changes in currency exchange rates, interest
rates, and equity prices. The company is exposed to market risks related to
currency exchange rates and interest rates.

      Currency exchange rate sensitivity - By the very nature of its global
operations, the company's cash flow and earnings are subject to fluctuations due
to exchange rate changes. However, because the company operates in a number of
locations around the world, currency exchange risk is well diversified.
Short-term debt of international affiliates is generally payable in local
currencies, which is in keeping with the company's policy of reducing currency
exchange exposures by offsetting local currency assets with local currency debt.

      Interest rate sensitivity - The company is exposed to changes in interest
rates primarily as a result of borrowing and investing activities used to
maintain liquidity and fund business operations. Because of the relatively short
maturities of temporary investments and the variable rate nature of industrial
development debt, these financial instruments were reported at carrying values
which approximate fair value at December 31, 2000. The incremental increase in
the fair value of fixed rate long term debt resulting from a hypothetical 10%
decrease in interest rates would be approximately $1.5 million. However, the
company's sensitivity to interest rate declines and the corresponding increase
in the fair value of its debt portfolio would unfavorably affect earnings and
cash flows only to the extent that the company elected to repurchase or retire
all or a portion of its fixed rate debt portfolio at prices above carrying
values.

Recently Issued Accounting Standards

      SEC Staff Accounting Bulletin No. 101, Revenue Recognition in Financial
Statements, which became effective in the fourth quarter of 2000, provides
guidance on the recognition, presentation, and disclosure of revenue in
financial statements. The effects of this guidance did not have a significant
impact on the company's financial statements.

      FASB Emerging Issues Task Force Issue No. 00-10, Accounting for Shipping
and Handling Costs, which became effective in the fourth quarter of 2000,
requires that shipping and handling costs billed to a customer in a sale
transaction be classified as revenue in the income statement. Adoption of this
guidance by the company, while not significant, increased both net sales and
cost of products sold by reclassifying shipping costs billed to customers.
Comparative financial statements for periods prior to fourth quarter 2000 were
restated to comply with this guidance.

      FAS No. 133, Accounting for Derivative Instruments and Hedging Activities,
effective January 1, 2001, establishes accounting and reporting standards for
derivative instruments, including those embedded in other contracts. The company
does not expect that adoption of this statement will have a significant effect
on its results or financial position.

Common Stock

      At December 31, 2000, there were 11,827,623 shares of common stock
outstanding. There were at least 875 identifiable common stockholders on
November 17, 2000, a recent date for dividends. Common stock price and volume
information is included on the American Stock Exchange under the symbol MSA. The
quarterly high and low price quotations and cash dividend information for common
shares, adjusted to reflect the three-for-one split in May 2000, follow:

Report of Independent Accountants

      To the Shareholders and Board of Directors of Mine Safety Appliances
Company

      In our opinion, the accompanying consolidated balance sheet and the
related consolidated statements of income, of changes in retained earnings and
accumulated other comprehensive income, and of cash flows present fairly, in all
material respects, the financial position of Mine Safety Appliances Company and
its subsidiaries at December 31, 2000 and 1999, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 2000, in conformity with accounting principles generally accepted
in the United States of America. These financial statements are the
responsibility of the Company's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with auditing standards generally
accepted in the United States of America which require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for our opinion.

      As discussed in Note 16 to the financial statements, the Company changed
the reporting period for certain subsidiaries in 1999.

22 | 2000 MSA Annual Report See notes to consolidated financial statements. Notes to Consolidated Financial Statements Note 1--Basis of Presentation Certain prior year balances have been reclassified to conform with the current year presentation. Significant accounting policies are stated in italics in the applicable notes to consolidated financial statements. THE PREPARATION OF FINANCIAL STATEMENTS IN CONFORMITY WITH GENERALLY ACCEPTED ACCOUNTING PRINCIPLES REQUIRES MANAGEMENT TO MAKE ESTIMATES AND ASSUMPTIONS THAT AFFECT THE REPORTED AMOUNTS OF ASSETS AND LIABILITIES AND DISCLOSURE OF CONTINGENT ASSETS AND LIABILITIES AT THE DATE OF THE FINANCIAL STATEMENTS AND THE REPORTED AMOUNTS OF REVENUES AND EXPENSES DURING THE REPORTING PERIOD. ACTUAL RESULTS COULD DIFFER FROM THOSE ESTIMATES. ALL SIGNIFICANT MAJORITY-OWNED COMPANIES, EXCEPT MINE SAFETY FUNDING CORPORATION, A QUALIFYING SPECIAL PURPOSE ENTITY, ARE INCLUDED IN THE CONSOLIDATED FINANCIAL STATEMENTS. INVESTMENTS IN WHICH THE COMPANY HAS AN EQUITY INTEREST OF 20% TO 50% ARE CARRIED AT EQUITY IN NET ASSETS. INTERCOMPANY TRANSACTIONS ARE ELIMINATED IN CONSOLIDATION. REVENUE FROM THE SALE OF PRODUCTS IS RECOGNIZED WHEN BOTH RISK OF LOSS AND TITLE HAVE TRANSFERRED TO THE CUSTOMER. PROPERTY IS STATED AT COST. DEPRECIATION IS BASED ON ESTIMATED USEFUL LIVES USING ACCELERATED AND STRAIGHT-LINE METHODS. MAINTENANCE AND REPAIRS ARE CHARGED TO EXPENSE. RENEWALS AND BETTERMENTS WHICH SUBSTANTIALLY EXTEND THE USEFUL LIFE OF PROPERTY ARE CAPITALIZED. PROFITS OR LOSSES RESULTING FROM DISPOSITIONS ARE INCLUDED IN INCOME. INTANGIBLE ASSETS, INCLUDING GOODWILL AND PATENTS, ARE AMORTIZED ON A STRAIGHT LINE BASIS OVER PERIODS NOT EXCEEDING 35 YEARS. THE FINANCIAL STATEMENTS OF COMPANIES FOR WHICH THE UNITED STATES DOLLAR IS DETERMINED TO BE THE FUNCTIONAL CURRENCY ARE TRANSLATED USING CURRENT AND HISTORIC EXCHANGE RATES; ADJUSTMENTS ARE INCLUDED IN INCOME FOR THE CURRENT PERIOD. THE FINANCIAL STATEMENTS OF ALL OTHER COMPANIES ARE TRANSLATED FROM THEIR FUNCTIONAL CURRENCY INTO UNITED STATES DOLLARS USING CURRENT EXCHANGE RATES; TRANSLATION ADJUSTMENTS ARE NOT INCLUDED IN INCOME BUT ARE ACCUMULATED IN A SEPARATE EQUITY ACCOUNT. TRANSACTION GAINS AND LOSSES ARE RECOGNIZED IN INCOME FOR THE CURRENT PERIOD. CASH AND CASH EQUIVALENTS IN THE CONSOLIDATED STATEMENT OF CASH FLOWS INCLUDES TEMPORARY INVESTMENTS THAT ARE READILY MARKETABLE AND HAVE MINIMAL RISK OF CHANGE IN VALUE. CERTAIN SECURITIES HAVE MATURITIES IN EXCESS OF NINETY DAYS; BUT, AS PART OF THE COMPANY'S CASH MANAGEMENT PROGRAM, MATURITIES ARE SCHEDULED BASED ON EXPECTED CASH NEEDS FOR THE ENSUING TWELVE MONTHS. COMPREHENSIVE INCOME, DETERMINED IN ACCORDANCE WITH STATEMENT OF FINANCIAL ACCOUNTING STANDARDS NO. 130, INCLUDES NET INCOME AND CHANGES IN OTHER COMPREHENSIVE INCOME ITEMS WHICH ARE REPORTED IN SHAREHOLDERS' EQUITY. OTHER COMPREHENSIVE INCOME IS REPORTED NET OF RELATED INCOME TAX EXPENSE OR BENEFIT. Note 2--Restructuring Restructuring charges of $2,433,000 in 2000, $3,960,000 in 1999, and $1,021,000 in 1998 relate to workforce reductions, primarily in Britain, Germany, and Canada in 2000, and in Germany in 1999 and 1998. Note 3--Research and Development Expense RESEARCH AND DEVELOPMENT COSTS, CHARGED AGAINST INCOME AS INCURRED, were $17,241,000 in 2000, $17,097,000 in 1999, and $17,415,000 in 1998.

OTHER INVENTORIES ARE VALUED AT THE LOWER OF COST, USING AVERAGE OR CURRENT STANDARD COSTS WHICH APPROXIMATE ACTUAL COSTS ON A FIRST-IN, FIRST-OUT (FIFO) BASIS, OR MARKET, DETERMINED BY REPLACEMENT COST OR NET REALIZABLE VALUE. Reductions in certain inventory quantities during 2000, 1999, and 1998 resulted in liquidations of LIFO inventory quantities carried at lower costs prevailing in prior years. The effect of these liquidations reduced cost of sales by $1,920,000 in 2000, $216,000 in 1999, and $320,000 in 1998, and increased net income by $1,171,000 ($.10 per share), $132,000 ($.01 per share), and $195,000 ($.01 per share), respectively.

On May 10, 2000, the company's shareholders approved a three-for-one stock split of both the issued and authorized common stock, which was distributed on May 24, 2000, to shareholders of record on May 12, 2000. During 2000, the company purchased 2.1 million shares of common stock from a major shareholder for $54.9 million. In a subsequent transaction, the company sold 1,125,000 shares of common stock that were held in treasury to the MSA Non-Contributory Pension Plan for Employees for $27 million. The Mine Safety Appliances Company Stock Compensation Trust was established to fund certain stock-related benefit plans, including employee stock options and awards. Shares held by the Stock Compensation Trust, and the corresponding cost of those shares, are reported as a reduction of common shares issued. Differences between the cost of the shares held by the Stock Compensation Trust and the market value of shares released for stock-related benefits are reflected in shares issued. The company has a Shareholder Rights Plan under which each outstanding share of common stock is granted one-third of a preferred share purchase right. The rights are exercisable for a fraction of a share of preferred stock, only if a person or group acquires or commences a tender offer for 15% or more of the company's common stock. In the event a person or group acquires 15% or more of the outstanding common stock, each right not owned by that person or group will entitle the holder to purchase that number of shares of common stock having a value equal to twice the $225 exercise price. The Board of Directors may redeem the rights for $.01 per right at any time until ten days after the announcement that a 15% position has been acquired. The rights expire on February 21, 2007.

Note 12--Pensions and Other Postretirement Benefits THE COMPANY'S NON-CONTRIBUTORY PENSION PLANS ARE ACCOUNTED FOR IN ACCORDANCE WITH STATEMENT OF FINANCIAL ACCOUNTING STANDARDS NO. 87 WHICH REQUIRES USE OF THE PROJECTED UNIT CREDIT COST METHOD TO DETERMINE THE PROJECTED BENEFIT OBLIGATION AND PLAN COST. THE PRINCIPAL U.S. PLAN IS FUNDED IN COMPLIANCE WITH THE EMPLOYEE RETIREMENT INCOME SECURITY ACT (ERISA). IT IS THE GENERAL POLICY TO FUND CURRENT COSTS FOR THE INTERNATIONAL PLANS EXCEPT IN GERMANY AND MEXICO, WHERE IT IS COMMON PRACTICE AND PERMISSIBLE UNDER TAX LAWS TO ACCRUE BOOK RESERVES. A minimum liability is recognized for unfunded defined benefit plans for which the accumulated benefit obligation exceeds accrued pension costs. The amount of the minimum liability in excess of unrecognized prior service cost, net of tax benefit, is recorded as a reduction in shareholders' equity. Non-contributory plan benefits are generally based on years of service and employees' compensation during the last years of employment. Benefits are paid from funds previously provided to trustees or are paid by the company and charged to the book reserves. The company provides certain health care benefits and limited life insurance for retired employees and their eligible dependents, THE COSTS FOR WHICH ARE ACCOUNTED FOR IN ACCORDANCE WITH STATEMENT OF FINANCIAL ACCOUNTING STANDARDS (SFAS) NO. 106.

For measurement purposes, a 7.5% increase in the costs of covered health care benefits was assumed for the year 2000, decreasing by .5% for each successive year to 4% in 2007 and thereafter. A one-percentage-point change in assumed health care cost trend rates would have increased or decreased the other postretirement benefit obligations and current year plan expense by approximately $1 million and $100,000, respectively. Expense for defined contribution pension plans was $2,619,000 in 2000, $2,750,000 in 1999, and $3,113,000 in 1998. Note 13--Acquisitions During 2000, the company acquired ISI Group, Inc. (ISIG), an established manufacturer of infrared thermal imaging cameras, and CairnsHelmets (Cairns), a leading supplier of firefighter head protection. The acquisitions were recorded using the purchase method of accounting. The aggregate purchase price of $29.7 million was allocated to the assets acquired and the liabilities assumed based on estimated fair values and included $24.9 million in goodwill, which is being amortized on a straight line basis over 10 years for ISIG and 35 years for Cairns. The results of operations of ISIG and Cairns are included in the financial statements from their respective dates of acquisition. The acquisition agreement for ISIG provides for additional consideration to be paid to the seller annually based on a defined calculation of gross profit from the sale of certain thermal imaging cameras in 2000 through 2003. Additional consideration will be charged to goodwill when paid and amortization expense will be adjusted to fully amortize ISIG goodwill by the end of the 10 year period. The following unaudited pro forma summary presents information as if ISIG and Cairns had been acquired at January 1, 1999: (In thousands, except earnings per share) 2000 1999 --------------------- Net sales................................................ $509,937 $515,785 Net income............................................... 23,551 15,624 Basic earnings per share................................. 1.91 1.20 The pro forma amounts include certain adjustments, primarily to recognize goodwill amortization and interest expense, and do not recognize any benefits which may be achieved from combining operations. The pro forma information does not necessarily reflect the actual results that would have occurred and is not necessarily indicative of future results of operations of the combined companies. 28 | 2000 MSA Annual Report Note 14--Leases The company leases office space, manufacturing and warehouse facilities, automobiles and other equipment under operating leases expiring at various dates through 2015. Rent expense was $5,700,000 in 2000, $5,813,000 in 1999, and $5,846,000 in 1998. Minimum rental commitments under noncancelable leases are $1,133,000 in 2001, $752,000 in 2002, $657,000 in 2003, $548,000 in 2004, $555,000 in 2005, and $5,227,000 after 2005. Note 15--Accounts Receivable Securitization STATEMENT OF FINANCIAL ACCOUNTING STANDARD NO. 125, ACCOUNTING FOR TRANSFERS AND SERVICING OF FINANCIAL ASSETS AND EXTINGUISHMENT OF LIABILITIES (FAS NO. 125), APPLIES A CONTROL-ORIENTED, FINANCIAL COMPONENTS APPROACH TO FINANCIAL-ASSET-TRANSFER TRANSACTIONS. FINANCIAL ASSETS, NET OF RETAINED INTERESTS, ARE REMOVED FROM THE BALANCE SHEET WHEN THE ASSETS ARE SOLD AND CONTROL IS SURRENDERED. IN SEPTEMBER 2000, FAS NO. 125 WAS REPLACED BY FAS NO. 140 WHICH REVISED CERTAIN ACCOUNTING AND DISCLOSURE REQUIREMENTS FOR SECURITIZATIONS AND OTHER TRANSFERS OF FINANCIAL ASSETS, BUT CARRIED OVER MOST FAS NO. 125 PROVISIONS. In November 1999, the company and Mine Safety Funding Corporation (MSF) entered into securitization agreements under which the company sells MSF, on a continuous basis, an undivided interest in eligible trade accounts receivable generated by the company, while maintaining a subordinated interest in a portion of the receivables. MSF is an unconsolidated wholly-owned special purpose, bankruptcy-remote subsidiary of the company. The company services the sold receivables for MSF at market rates and, accordingly, no servicing asset or liability has been recorded. MSF and the company have also entered into securitization agreements with financial institutions under which MSF may sell up to $30 million of accounts receivable to a multi-seller asset-backed commercial paper issuer. At December 31, 2000, accounts receivable of $53.2 million were owned by MSF. The company held a subordinated interest in these receivables of $31.5 million, of which $30.5 million is classified as other receivables. Net proceeds to the company from the securitization arrangement were $21.0 million at December 31, 2000. The company incurred costs associated with the securitization facility of $2.4 million in 2000, representing the discount loss on the sale of the receivables, partially offset by related servicing income. At December 31, 1999, accounts receivable of $43.3 million were owned by MSF. The company held a subordinated interest in these receivables of $23.7 million, of which $22.7 million is classified as other receivables. Net proceeds to the company from the securitization arrangement were $18.7 million at December 31, 1999. The company incurred costs associated with the securitization facility of $300,000 in 1999, representing the discount loss on the sale of the receivables, partially offset by related servicing income. Note 16--Change in Reporting Period Beginning in 1999, certain international affiliates which had been consolidated based on fiscal years ending November 30 changed to fiscal years ending December 31. The after-tax effect of the change in reporting period is included in the 1999 income statement as a change in accounting principle.

(695) ------- Change in reporting period, net of tax........................ (1,192) Note 17--Recently Issued Accounting Standards In June 1998, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 133, Accounting for Derivative Instruments and Hedging Activities (FAS No. 133), which later was amended by FAS Nos. 137 and 138. FAS No.133 requires the recognition of all derivatives, including those embedded in other contracts, as either assets or liabilities at fair value. Changes in fair value are to be reflected in either current period net income or other comprehensive income, depending on the designation of the derivative instrument. The company may elect not to designate a derivative instrument as a hedge even if the strategy would be expected to qualify for hedge accounting treatment. The adoption of FAS No. 133 will change the timing of recognition for derivative gains and losses as compared to previous accounting standards. The company will adopt FAS No.133 effective January 1, 2001. The company does not expect that adoption of this statement will have a significant effect on its results or financial position. 29 | 2000 MSA Annual Report Notes to Consolidated Financial Statements Note 18--Stock Plans The 1998 Management Share Incentive Plan permits the granting of restricted stock awards and stock options to eligible key employees through March 2008. The 1990 Non-Employee Directors' Stock Option Plan provides for annual grants of stock options to eligible directors. As of December 31, 2000, there were 1,260,114 shares and 83,400 shares, respectively, reserved for future grants pursuant to these plans. THE COMPANY APPLIES ACCOUNTING PRINCIPLES BOARD OPINION 25 AND RELATED INTERPRETATIONS IN ACCOUNTING FOR THE PLANS. ACCORDINGLY, NO COMPENSATION COST IS RECOGNIZED FOR STOCK OPTION GRANTS. COMPENSATION COST FOR RESTRICTED STOCK AWARDS IS MEASURED BY THE MARKET VALUE OF THE SHARES WHEN AWARDED AND IS AMORTIZED BY CHARGES TO OPERATIONS OVER THE PERIOD THAT THE EMPLOYEE PROVIDES THE SERVICE. Restricted stock awards are granted to employees without payment to the company in consideration of services to be performed in ensuing four-year periods. Restricted stock awards of 19,760 shares (pre-split), with a fair value of $63.06 per share, were granted in 2000. Restricted stock awards expense charged to operations was $547,000 in 2000, $448,000 in 1999, and $368,000 in 1998. Stock options are generally granted at market value option prices and expire after ten years (limited instances of option prices in excess of market value and expiration after five years). If compensation cost for stock option grants had been determined based on the fair value method provided in Statement of Financial Accounting Standards No. 123, proforma net income in 2000, 1999 and 1998 would have been $21,775,000, $14,609,000, and $17,805,000 and earnings per basic share would have been $1.77, $1.13, and $1.34, respectively. The fair value of the options granted was estimated at the grant date using the Black-Scholes option pricing model and the following weighted average assumptions for options granted in 2000, 1999, and 1998, respectively: risk-free interest rate of 7.0%, 5.1%, and 5.5%; dividend yield of 2.3%, 2.2%, and 2.0%; expected option life of 9.8 years, 9.8 years, and 9.7 years; and expected volatility factor of 19% in all three years. A summary of stock option activity under the two plans, adjusted to reflect the three-for-one stock split in May 2000, follows:
2000 1999 1998 ------------------------------------------------------------------------------------ Weighted-Average Weighted-Average Weighted-Average Shares Exercise Price Shares Exercise Price Shares Exercise Price ------------------------------------------------------------------------------------ Outstanding at beginning of year.... 305,379 $19.24 215,715 $18.25 165,003 $16.88 Granted............................. 267,120 21.11 101,844 21.24 87,252 20.62 Exercised...........................

The weighted average remaining contractual life of all options outstanding at December 31, 2000 was approximately 7 years. Weighted average remaining contractual life by exercise price range is summarized as follows: Exercise prices of $13.48 to $15.71 - 4 years Exercise prices of $18.33 to $23.88 - 8 years Note 19--Quarterly Financial Information (Unaudited) (In thousands, except earnings per share)

Fourth quarter 1999 net income and earnings per share include a loss of $1,192,000 or $.09 per share resulting from the change in reporting period. The effect of this change on full year 1999 net income and earnings per share was $1,192,000 or $.09 per share. Shipping charges billed to customers have been reclassified from cost of products sold to net sales to comply with FASB Emerging Issues Task Force Issue 00-10, Accounting for Shipping and Handling Costs. Amounts reclassified in the first, second, third, and fourth quarters of 2000 were $1,018,000, $980,000, $994,000, and $945,000, respectively, and for the first, second, third, and fourth quarters of 1999 were $912,000, $958,000, $885,000, and $926,000, respectively. Earnings per share information has been adjusted to reflect the three-for-one stock split in May 2000. 30 | 2000 MSA Annual Report Summary of Selected Financial Data
