MINE SAFETY APPLIANCES COMPANY MANAGEMENT'S DISCUSSION AND ANALYSIS Most of the sales increase was due to the inclusion of HAZCO Services, Inc., Dayton, Ohio, which was acquired in the last half of 1993. This acquisition added equipment rental services and a significant presence in the hazardous materials/ environmental market. U.S. commercial safety equipment sales have been essentially flat, while sales of gas detection and monitoring instruments and specialty chemicals have maintained robust growth. Shipments of gas masks to the U.S. military have continued at reduced levels, although some modest improvement in the second half of this year is expected. Sales by the company's German and selected European affiliates remained depressed by economic conditions. Business grew particularly in Asia and Australia, while overall sales in other international markets have been firm. The increase in other income in the second quarter of 1994 was primarily due to an increase in rental income. The major contributors to the earnings increase were HAZCO, the U.S. Instrument Division and certain international operations. Operating earnings trends in 1994 in the U.S. were meaningfully better than net profit movement due to transitional expenses to reengineer the company's customer communications, distribution and cost management processes. European operations, although depressed by economic conditions, have improved as a result of restructuring. Earnings have shown encouraging growth in Canada, Australia and Asia to historically high levels. Latin American results, though, remain unsatisfactory. Earnings per share have benefitted from higher net income and reduced shares outstanding as a result of the share repurchase program. These results represent another step along the journey to return MSA to a satisfactory level of performance with a good way yet to travel. The company continues its strategy of particularly emphasizing innovation in products, services and business processes with the goals of improved customer response and lower cost. This will enhance growth in expanding markets and improve profitability in weak markets. We will also continue selective geographic extension of MSA's activities. The company has made progress in overcoming some unfavorable economic and market trends. We will continue to move forward in our journey. If external factors become neutral or more favorable, our speed along the way could accelerate. Comparative foreign currency exchange losses charged to income are as follows:

Currency exchange adjustments charged directly to the equity cumulative translation adjustments account are shown below. Significant second quarter 1994 translation gains relate primarily to Germany, Australia,and Italy. Year to date 1993 translation losses relate primarily to Spain and Italy.

Available credit facilities along with internal cash resources are adequate to provide for ensuing capital requirements. The company's financial position and liquidity continue to be adequate. The current ratio and term debt in relation to capital as of June 30, 1994 were 3.7 and 8.2%, respectively, as compared to 3.7 and 11.0% at December 31, 1993.

                  In compliance with the requirements of Article VIII of the
Business Corporation Law, approved the 5th day of May, 1933, P.L. 364 as
amended, the applicant, MINE SAFETY APPLIANCES COMPANY, desiring to amend its
Restated Articles, hereby certifies under its corporate seal that:


                  1.       The name of the corporation is MINE SAFETY
APPLIANCES COMPANY, and the location of its registered office in the
Commonwealth of Pennsylvania is 121 Gamma Drive, RIDC Industrial Park, O'Hara
Township, Pittsburgh, Allegheny County, Pennsylvania 15238.

                  2.       The corporation was incorporated on January 25, 1917
under the Act of the General Assembly of the Commonwealth of Pennsylvania,
approved April 29, 1874, P.L. 73, and the several supplements hereto, and is
now subject to the provisions of the Business Corporation Law.

                  3.       The meeting of the shareholders of the corporation
at which the amendment was adopted was held on April 19, 1989 at 10:00 a.m.,
local Pittsburgh time, at the corporation's Executive Offices, 121 Gamma Drive,
RIDC Industrial Park, O'Hara Township,


Pittsburgh, Pennsylvania, pursuant to written notice mailed on March 13, 1989.

                  4.       At the time of the action of the shareholders (a)
the total number of shares outstanding was 6,578,314 shares of common stock,
without par value, and 26,290 shares of 4 1/2% cumulative preferred stock, par
value $50 per share, and (b) the number of shares entitled to vote on the
proposed amendment was 6,578,314 shares of common stock.

                  5.       In the action taken by the shareholders, the number
of shares voted for the proposal to amend was 5,036,017 shares of common stock,
and the number of shares voted against the proposal to amend was 478,137 shares
of common stock.

                  6.       The amendment adopted by the shareholders was to add
to Article 7th of the restated Articles of the corporation a new Section 7.9 to
read as set forth in full below:

                  7.9.    Applicability of BCL Section 910; Suspension of
Article 7th.  Section 910 of the Pennsylvania Business Corporation Law ("BCL
Section 910") shall be applicable to the Company, and the provision of the
By-Laws providing to the contrary is hereby repealed. For so long as BCL
Section 910 as in effect on the date of approval by the Board of Directors of
this Section 7.9 (the "Approval Date") or amendatory or replacement legislation
substantially equivalent in effect thereto shall remain in effect and
applicable to the Company, Sections 7.1 through 7.8 of this Article 7th shall
be suspended.  In the event that the Disinterested Directors by majority vote
shall determine (the date of any such determination being referred to herein as
the "Determination Date") that BCL Section 910 has been repealed in whole or in
part or invalidated in whole or in part by any court or amended or replaced by
other legislation such that provisions


substantially equivalent in effect to BCL Section 910 as in effect on the
Approval Date shall not be applicable to the Company, then unless and until
such determination shall be rescinded (whether by reason of further legislation
or court decisions or otherwise) by a majority vote of the Disinterested
Directors, Sections 7.1 through 7.8 of this Article 7th shall no longer be
suspended and shall apply in the event that any Acquiring Person is on the
Determination Date or thereafter becomes a 40% Shareholder.  In the event that
the Company has received prior to the Determination Date credible notice that
an Acquiring Person has become a 40% Shareholder, then, notwithstanding Section
7.1, the term "Effective Date" as used in this Article 7th shall mean the
Determination Date. In determining whether provisions substantially equivalent
in effect to those of BCL Section 910 on the Approval Date remain in effect and
applicable to the Company, the Disinterested Directors may consider, in
addition to whether any legislation then applicable to the Company provides
substantially equivalent or greater rights to the shareholders of the Company,
whether such legislation contains exclusions from the coverage of such
legislation which are in practical effect substantially equivalent in coverage
to those provided in clauses (a), (b) and (c) of BCL Section 910(B)(2)(ii) as
in effect on the Approval Date. Nothing contained in this Section 7.9 shall
prevent the Board of Directors from exercising any right provided by any
amendment to BCL Section 910 or any replacement or other legislation to opt out
from coverage of such legislation and, if appropriate, determining on such
basis that the suspension of Articles 7.1 through 7.8 provided for herein has
been terminated.

         IN TESTIMONY WHEREOF, the undersigned corporation has caused these
Articles of Amendment to be signed by its President and its corporate seal,
duly attested by its Secretary, to be affixed onto this document this 25th day
of April, 1989.

RESTATED ARTICLES
        OF
MINE SAFETY APPLIANCES COMPANY




     Article 1st. The name of the corporation is MINE SAFETY APPLIANCES COMPANY
(hereinafter the "Company").

     Article 2nd. The location and post office address of its current
registered office in this Commonwealth is 201 North Braddock Avenue,
Pittsburgh, Allegheny County, Pennsylvania 15208.

     Article 3rd. The Company is organized under the provisions of the Business
Corporation Law for the following purposes, which shall be construed
independently of each other:

          (a) To manufacture, develop, prepare, install, buy, sell, maintain,
     service, lease as lessor and lessee, import, export and otherwise deal in
     and with all types of appliances, equipment, apparatus, instruments,

          (c) To engage in mercantile, manufacturing, processing, research,

     of which is a direct or indirect benefit to the Company.

The Company shall also have unlimited power to engage in and to do any lawful
act concerning any or all lawful business for which corporations may be
incorporated under the Business Corporation Law.

     Article 4th. The term of its existence is perpetual.

     Article 5th. The aggregate number of shares which the Company shall have
authority to issue shall be 21,100,000 shares, divided into three classes so
that 100,000 shares shall be 4 1/2% Cumulative Preferred Stock of the par value
of $50 per share (hereinafter referred to as the "4 1/2% Preferred Stock"),
1,000,000 shares shall be Second Cumulative Preferred Stock of the par value of
$10 per share (hereinafter referred to as the "Second Preferred Stock"), and
20,000,000 shares shall be Common Stock without par value.

     A description of said classes of stock and a statement of the preferences,
qualifications, privileges, limitations, options, conversion rights, and other
special or relative rights granted to or imposed upon the shares of each class
are as follows:


Section I. 4 1/2% Cumulative Preferred Stock.

     A. DIVIDENDS. The holders of 4 1/2% Preferred Stock shall be entitled to
receive and the Company shall be required to pay, when and as declared by the
Board of Directors, out of any assets or funds of the Company available for the
payment of dividends in accordance with law, dividends at the rate of 4 l/2% per
annum payable quarterly upon the first day of March, June, September and
December in each year. Dividends on the 4 1/2% Preferred Stock shall be
cumulative from the first day of the quarterly dividend period in which such
shares are issued, whether or not earned or declared, but arrears in payment
thereof shall not bear interest. The said 4 1/2% Preferred Stock shall be

preferred over the shares of all other classes of the Company's stock
(hereinafter referred to as "Junior Stock"). No dividends shall be paid upon,
nor shall any distribution be ordered or made, in respect of the Junior Stock
of the Company in any year while any dividends are accumulated and unpaid upon
the 4 1/2% Preferred Stock and unless and until dividends at the rate aforesaid
for the current year shall have been declared and paid or set apart for the 4
1/2% Preferred Stock. So long as any of the 4 1/2% Preferred Stock shall be
outstanding, the Company shall not pay or declare any dividend (except
dividends payable in its shares of a class ranking junior to the 4 1/2%
Preferred Stock as to dividends and assets) on any shares of Junior Stock which
will reduce the earned surplus of the Company below an amount equal to 50% of
the par value of the shares of said 4 1/2% Preferred Stock outstanding as of
the time any such calculation is required to be made.

     B. REDEMPTION. On and after December 1, 1955, the Board of Directors of
the Company, at its option, may redeem at any time or from time to time the
whole or any part of the 4 1/2% Preferred Stock at the redemption price of
$52.50 per share plus all accrued and unpaid dividends on such shares at the
date fixed for redemption. Notice of each such intended redemption shall be
given by publication at least once in each of two successive calendar weeks, in
each case on any day of the week, in a daily newspaper of general circulation
in the City of Pittsburgh, Allegheny County, Pennsylvania, the first
publication to be made not less than thirty (30) days nor more than sixty (60)
days prior to the date fixed for such redemption. A similar notice shall be
mailed by the Company, postage prepaid, not less than thirty (30) days nor more
than sixty (60) days prior to the date fixed for such redemption, to the
holders of record of the shares to be redeemed, addressed to each such
shareholder at his address as the same appears upon the stock transfer books of
the Company, but failure to mail such notice or any defect therein or in the
mailing thereof shall not affect the validity of the proceedings for the
redemption of any shares of the 4 1/2% Preferred Stock to be redeemed, and the
mailing of such notice shall not be a condition of such redemption. In case of
redemption of only a part of the outstanding shares of the 4 1/2% Preferred
Stock, the shares to be redeemed shall be selected by lot or pro rata as the
Board of Directors shall determine. On or after the date of redemption stated
in such notice, each holder of the shares of the 4 1/2% Preferred Stock called
for redemption shall surrender his certificate for such shares to the Company
at the place designated in such notice, and shall thereupon be entitled to
receive payment of the redemption price. In case less than all the shares
represented by such surrendered certificate are redeemed, a new certificate
shall be issued representing the non-redeemed shares. If the aforesaid notice
of redemption shall have been duly published, and if, on or before the
redemption date specified in such notice, the funds necessary for such
redemption shall have been deposited in trust for such purpose with a bank or
trust company in good standing, designated in such notice, doing business in
the City of Pittsburgh, Pennsylvania, from and after the date of redemption so
designated, notwithstanding that any certificate for shares of 4 1/2% Preferred
Stock so called for redemption shall not have been surrendered for
cancellation, the shares represented thereby so called for redemption shall no
longer be deemed outstanding, the dividends on the number of shares called for
redemption represented thereby shall cease to accrue, and all rights with
respect to the shares of 4 1/2% Preferred Stock so called for redemption shall
forthwith after such redemption date cease and determine, except only the right
of the holder to receive out of the moneys so deposited the redemption price,
but without interest thereon. None of the 4 1/2% Preferred Stock so redeemed by
the Company shall be reissued, and no 4 1/2% Preferred Stock shall be issued in
lieu thereof or in exchange therefor, and the Company shall from time to time
cause all of such 4 1/2% Preferred Stock so redeemed to be cancelled and its
capital reduced in the manner provided by law.

     Nothing in this Subparagraph B contained shall prevent the purchase by the
Company of the whole or any part of the 4 1/2% Preferred Stock, so long as
dividends thereon are not in arrears, at public or private sale, or upon call
for tender, upon such terms as the Board of Directors may prescribe, and at
prices not to exceed the redemption price thereof and all accrued and unpaid
dividends on the shares so purchased to the date of purchase.

     C. DISTRIBUTION ON LIQUIDATION OR DISSOLUTION. The 4 1/2% Preferred Stock
shall be preferred over all shares of Junior Stock as to assets, and in the
event of any liquidation or dissolution or winding up of the Company, the
holders of such stock shall be entitled to receive out of the assets of


the Company available for distribution to its shareholders, whether from
capital, surplus or earnings, the preferential amounts hereinafter provided for
each share held by them before any distribution of the assets shall be made to
the holders of shares of Junior Stock, but the holders of such 4 1/2% Preferred
Stock shall be entitled to no other or further amounts. Upon liquidation,
dissolution or winding up of the Company, the holders of the 4 1/2% Preferred
Stock shall be entitled to receive the sum of $50 per share if such
liquidation, dissolution or winding up be involuntary, and the redemption price
of such stock hereinbefore provided if such liquidation, dissolution or winding
up be voluntary, together in either case with all accrued and unpaid dividends
on such shares to the date fixed for payment of such preferential amounts.

     D. VOTING RIGHTS. Except as otherwise herein provided or otherwise
required by law, the entire voting power of the Company shall be vested
exclusively in the holders of its Junior Stock. If at any time dividends
payable on the 4 1/2% Preferred Stock shall be accrued and unpaid in an amount
equivalent to or exceeding six quarterly dividends then, and in such event, the
holders of the 4 1/2% Preferred Stock shall be entitled, voting separately as a
class, to elect two directors, at all elections of directors, in addition to
the directors to be elected by the holders of the Junior Stock, but such voting
power and the terms of office of any directors so elected by the holders of the
4 l/2% Preferred Stock shall continue only until, and shall cease when, all
accrued and unpaid dividends on such stock to the beginning of the then current
dividend period shall have been paid in full or funds for the payment thereof
shall have been set apart, subject always to the same provisions for the
revesting of such voting power in the case of any similar future default or
defaults. In such election, the holders of 4 1/2% Preferred Stock shall be
entitled to one vote per share. A meeting of the holders of the 4 1/2%
Preferred Stock having voting power may be called upon notice to such holders
similar to that provided in the By-Laws for shareholders' meetings, at the
expense of the Company at any time after the accrual of such voting power and
prior to the next annual meeting of shareholders (and the termination of such
voting power), by the holders of not less than 10% of the 4 1/2% Preferred
Stock then outstanding.

     E. RESTRICTION ON CORPORATE ACTION. Except upon the affirmative vote or
written consent of the holders of record of at least 60% of the aggregate
number of shares of the 4 1/2% Preferred Stock at the time outstanding (in
addition to any other vote or consent at the time required by law) the Company
shall not in any manner, whether by amendment of the Articles, by sale of all
or substantially all the Company's assets or business, by merger or
consolidation, or otherwise.

          (a) amend, alter or repeal any of the provisions of the Articles     
     so as to affect adversely the relative rights, preferences or powers of   
     the 4 1/2% Preferred Stock; or

          (b) authorize, or increase the authorized amount of, the 4 1/2%      
     Preferred Stock or any class or series of stock ranking senior to or on a 
     parity with the 4 1/2% Preferred Stock in the payment of dividends or the 
     preferential distribution of assets;

     Provided, however, that no such vote or consent shall be required for any
sale of all or substantially all the Company's assets or business or for any
merger or consolidation if (i) such holder of shares of 4 1/2% Preferred Stock
immediately prior thereto shall thereafter and in connection therewith continue
to hold or shall receive the same number of shares of preferred stock, with the
same relative rights, preferences and powers, of such acquiring, surviving or
resulting corporation, or (ii) the authorized capital stock of the acquiring,
surviving or resulting corporation immediately thereafter shall include only
classes of stock for which no such vote or consent would have been required for
the authorization thereof under clauses (a) or (b) above; and Provided Further,
However, that no such consent shall be required under the provisions of this
Subparagraph E if, at or prior to the time when the act with respect to which
such vote would otherwise be required shall be effected, provision is made in
accordance with the Articles for the redemption of all shares of 4 1/2%
Preferred Stock at the time outstanding.

     For the purpose of obtaining the affirmative vote or written consent of
the holders of any specified number of shares of 4 1/2% Preferred Stock at the
time outstanding there shall be excluded, in computing the number of shares
outstanding, and there shall be excluded from voting, all shares of such stock
owned directly or indirectly by or for the account of the Company.


Section II. Second Cumulative Preferred Stock.

     A. AUTHORITY OF BOARD; VARIATIONS IN SERIES. The shares of Second
Preferred Stock may be divided into and issued in series. Authority is hereby
expressly vested in the Board of Directors of the Company, at any time or from
time to time, by resolution to divide any or all of the shares of the Second
Preferred Stock into series, and to fix and determine the designation and the
relative rights and preferences of any series so established, to the fullest
extent now or hereafter permitted by the laws of the Commonwealth of
Pennsylvania, including, but not limited to, the variations between different
series in the following respects:

          (i) the rate of dividend upon the shares of such series;

          (ii) the price or prices at which, and the terms and conditions on   
     which, the shares of such series may be redeemed at the option of the     
     Company;

          (iii) the amount or amounts payable upon the shares of such series in
     the event of voluntary or involuntary liquidation;

          (iv) the obligation, if any, of the Company to purchase, redeem      
     and/or retire shares of such series pursuant to a sinking fund;

          (v) the terms and conditions upon which shares of such series may be 
     converted, in the event that the shares of such series are issued with the
     privilege of conversion;

          (vi) the voting rights, if any, of the holders of shares of such     
     series; and

          (vii) the relative seniority, parity or junior rank of such series   
     with respect to other series of Second Preferred Stock then or thereafter 
     to be issued.

     The Board of Directors is hereby expressly authorized (a) to fix the
number of shares which shall constitute any series of Second Preferred Stock,
which number may at any time or from time to time be increased or decreased
(but not below the number of shares thereof then outstanding), unless the Board
of Directors shall have otherwise provided in establishing such series; (b) to
fix the dates in each year on which dividends upon any such series shall be
payable, and the date or dates from which such dividends shall be cumulative;
and (c) to fix and determine such other terms, limitations and relative rights
and preferences, if any, of any such series as it may now or hereafter lawfully
do under the laws of the Commonwealth of Pennsylvania.

     B. VOTING RIGHTS. (i) Except as otherwise provided in these Articles or in
the resolution or resolutions establishing any series of Second Preferred
Stock, the holders of Common Stock shall exclusively have the sole voting power.

     (ii) If at the time of any annual meeting of shareholders a default in
preference dividends on the Second Preferred Stock, as hereinafter defined,
shall exist, the number of directors constituting the Board of Directors of the
Company shall be increased by two, and the holders of the Second Preferred
Stock, voting separately as a class without regard to series, shall, to the
exclusion of the holders of the 4 1/2% Preferred Stock (whose voting rights upon
default in dividends are hereinabove described in Section I) and the holders of
Common Stock, have the right at such meeting to elect two directors of the
Company to fill such newly created directorships. Such right shall continue
until there are no dividends in arrears upon the Second Preferred Stock. Each
director elected by the holders of the Second Preferred Stock, voting as a
class as aforesaid (herein called a Second Preferred Director), shall continue
to serve as such director for the full term for which he shall have been
elected, notwithstanding that prior to the end of such term a default in
preference dividends shall cease to exist. Any Second Preferred Director may be
removed by, and shall not be removed except by, the vote of the holders of
record of the outstanding shares of Second Preferred Stock, voting separately
as a class without regard to series, at a meeting of the shareholders, or of
the holders of shares of Second Preferred Stock, called for the purpose. So
long as a default in any preference dividends on the Second Preferred Stock
shall exist any vacancy in the office of a Second Preferred Director may be
filled either by an instrument in writing signed by the remaining Second
Preferred Director and filed with the Company or by the vote of the holders of


the outstanding Second Preferred Stock, voting separately as a class without
regard to series. Whenever the term of office of the Second Preferred Directors
shall end and a default in preference dividends shall no longer exist, the
number of directors shall be the number otherwise specified without reference
to the provisions of this Subparagraph B. For the purposes of this Subpara-
graph B, a default in preference dividends on the Second Preferred Stock shall
be deemed to have occurred whenever the amount of dividends accrued or in
arrears upon any series of the Second Preferred Stock shall be equivalent to
six full quarter-yearly (or three full semi-annual) dividends or more, and,
having so occurred, such default shall be deemed to exist thereafter until all
dividends accrued or in arrears on all shares of Second Preferred Stock then
outstanding, of each series, shall have been paid to the end of the last
preceding quarterly dividend period.

     (iii) Except upon the affirmative vote of the holders of at least 60% of
the aggregate number of shares of Second Preferred Stock at the time
outstanding (in addition to any other vote at the time required by law), the
Company shall not in any manner, whether by amendment of the Articles, by sale
of all or substantially all the Company's assets or business by merger or
consolidation, or otherwise,

          (a) amend, alter or repeal any of the provisions of the Articles so  
     as to affect adversely the relative rights, preferences or powers of the  
     Second Preferred Stock, or

          (b) authorize, or increase the authorized amount of, the Second      
     Preferred Stock or any class or series of stock ranking senior to or on a 
     parity with the Second Preferred Stock in the payment of dividends or the 
     preferential distribution of assets;

     Provided, However, that no such vote shall be required for any sale of all
or substantially all the Company's assets or business or for any merger or
consolidation if (x) each holder of shares of Second Preferred Stock
immediately prior thereto shall thereafter and in connection therewith continue
to hold or shall receive the same number of shares of preferred stock, with the
same relative rights, preferences and powers, of such acquiring, surviving or
resulting corporation, and (y) the authorized capital stock of the acquiring,
surviving or resulting corporation immediately thereafter shall include only
classes of stock for which no such vote would have been required for the
authorization thereof under clauses (a) or (b) above; and Provided Further,
However, that no such vote shall be required under the provisions of clause
(iii) of this Subparagraph B if, at or prior to the time when the act with
respect to which such vote would otherwise be required shall be effected,
provision is made in accordance with the Articles for the redemption of all
shares of Second Preferred Stock at the time outstanding.


Section III. Preemptive Rights.

     No holder of any shares of any class of stock shall be entitled to have
any right, as such holder, to subscribe for or to purchase

          (a) any part of any issue of shares of any class whatsoever, which   
     the Company may hereafter issue or sell; or

          (b) any obligations or securities of whatsoever kind and character   
     which the Company may hereafter issue or sell, convertible into or        
     exchangeable for any shares of the Company of any other class or classes, 
     or to which shall be attached or shall appertain any warrant or warrants  
     or other instruments which shall confer upon the holder or owner thereof  
     the right to subscribe for or purchase from the Company any of its shares 
     of any class or classes;

whether such shares, obligations or securities hereafter issued shall be part
of the number of shares authorized by the Articles as now or hereafter amended,
or whether such shares, obligations or securities hereafter issued shall be
part of any new or additional issue of shares, obligations or securities of any
class whatsoever. The approval of this amendment shall be effective to
eliminate and deny any preemptive rights which may have existed in respect of
any outstanding shares.


Section IV. Non-Cumulative Voting of Second Preferred Stock and Common Stock.

     No holder of Second Preferred Stock and no holder of Common Stock shall
have any right to cumulate his votes and cast them for one candidate or
distribute them among two or more candidates in any election of directors.

Stock deemed to be outstanding shall include shares deemed owned by such Person
through application of this paragraph (d) but shall not include any other
shares of Voting Stock which may be issuable pursuant to any agreement,
arrangement or understanding, or upon exercise of conversion rights, warrants
or options, or otherwise.

     (e) The term "Business Combination" shall mean:

          (i) any merger, consolidation or share exchange of the Company or a  
     Subsidiary of the Company with an Acquiring Person or into or with another
     Person which is or after such merger, consolidation or share exchange     
     would be an Affiliate or an Associate of an Acquiring Person, in each case
     without regard to which entity is the surviving entity;

          (ii) any sale, lease, exchange or other disposition (whether in one  
     transaction or a series of related transactions), including without       
     limitation a mortgage or any other security device, of all or any         
     Substantial Part of the assets of the Company (including without          
     limitation any voting securities of a Subsidiary of the Company) or of a  
     Subsidiary of the Company to an Acquiring Person or of all or any         
     Substantial Part of the assets of an Acquiring Person to the Company or a 
     Subsidiary of the Company;

          (iii) the issuance, transfer or delivery of any securities of the

     Subsidiaries to an Acquiring Person, or of any securities of an Acquiring 
     Person by the Acquiring Person to the Company or a Subsidiary of the     
     Company (other than issuance or transfer of securities which is effected  
     or offered on a pro rata basis to all shareholders of the Company or of   
     the Acquiring Person, as the case may be):

          (iv) any recapitalization, reorganization, reclassification of       
     securities (including any reverse stock split) or other transaction or    
     series of related transactions involving the Company that would have the

     Acquiring Person; or

          (v) the adoption of any plan or proposal for the liquidation or      
     dissolution of the Company in which an Acquiring Person owning shares of  
     any class of the Company is treated differently from other shareholders   
     of the same class (other than dissenting shareholders exercising          
     statutory appraisal rights).

     As used in this definition, a "series of related transactions" shall be
deemed to include not only a series of transactions with the same Acquiring
Person but also a series of separate transactions with different Persons all
included in the definition of Acquiring Person.

     (f) The Term "Disinterested Director" at any time shall mean any director
of the Company at the time in office except that if at any time there exists an
Acquiring Person, then the term shall mean a director of the Company who is
unaffiliated with and not a representative of any Acquiring Person and either
(i) was a director of the Company immediately prior to the time that the
Acquiring Person became an Acquiring Person or (ii) shall have been recommended
for election by a majority of the then Disinterested Directors. Where any
provision in the Articles calls for a determination, recommendation or approval
by a majority of the Disinterested Directors, if there is at any particular
relevant time no Disinterested Director in office, then such provision shall be
deemed to be satisfied if the Board, by a two-thirds vote of all the Directors


in office, makes or gives such determination, recommendation or approval.

     (g) The term "Fair Market Value" means: (i) in the case of stock, the
highest closing sale price on the date in question of a share of such stock on
the Composite Tape for the New York Stock Exchange Listed Stocks, or, if not so
quoted, on the New York Stock Exchange, or if not so listed, on the principal
United States securities exchange registered under the Securities Exchange Act
of 1934 on which such stock is listed, or, if not so listed, the closing sale
or, if none, the closing bid quotation with respect to a share of such stock on
the date in question on the National Association of Securities Dealers, Inc.
Automated Quotations System or any system then in use, or if no such quotations
are available, the fair market value on the date in question of a share of such
stock without regard to any depreciation thereof in consequence of any Business
Combination then proposed, as determined by a majority of the Disinterested
Directors in good faith; and (ii) in the case of property other than cash or
stock, the fair market value of such property on the date in question as
determined by a majority of the Disinterested Directors in good faith.

     (h) The term "Person" shall mean any individual, partnership, corporation,
group or other entity. When two or more Persons act as a partnership, limited
partnership, syndicate, association or other group for the purpose of
acquiring, holding or disposing of shares of stock, such partnership,
syndicate, association or group shall be deemed a "Person". As used herein, the
pronouns "which", "that" and "it" in relation to Persons that are individuals

appropriate.

     (i) The term "Subsidiary" of any Person shall mean any corporation of

     (k) A specified percentage of "Voting Power", with reference to any matter
being voted upon by the shareholders, shall mean such number of shares of stock
as shall enable the holders thereof to cast such percentage of the total number
of votes entitled to be cast by holders of shares entitled to vote thereon.

     (I) The term "Voting Stock'' at any time shall mean outstanding shares of
capital stock of a corporation entitled to vote at its next annual election of
directors (without consideration of the rights of any class of stock other than
the Common Stock to elect directors by a separate class vote).

     6.2. Authority of Disinterested Directors. The Disinterested Directors, by
a majority vote, are authorized to determine on the basis of information known
to them after reasonable inquiry: (i) whether a Person is an Acquiring Person,
(ii) the number of shares of Voting Stock Beneficially Owned by any Person,
(iii) whether a Person is an Affiliate or Associate of another, (iv) whether
certain assets constitute a Substantial Part of the assets of any Person and
(v) any other fact required to be determined in the application of Articles
6th, 7th, 10th, 11th or 12th of the Articles of the Company. The Disinterested
Directors, by a majority vote, are authorized to interpret all the terms and
provisions of Articles 6th, 7th, 10th, 11 th or 12th of the Articles of the
Company. Any such determination or interpretation made in good faith shall be
binding and conclusive on all parties.

     6.3. Fiduciary Obligations. Nothing contained in Articles 6th, 7th, 10th,
11th or 12th of the Articles shall be construed to relieve any Acquiring Person
from any fiduciary obligation imposed by law.

     Article 7th. Repurchase Rights.

     7.1. Triggering Events. Except as provided below, in the event that any
Acquiring Person (hereinafter referred to as a "40% Shareholder") becomes the


Beneficial Owner of shares representing more than forty percent of the Voting
Power of the outstanding Voting Stock of the Company, each Person who is a
holder of shares of Voting Stock of the Company at any time until and including
the 90th day following the date the notice referred to in Section 7.2 below is
mailed, other than the 40% Shareholder or a transferee of the 40% Shareholder,
shall have the right, until and including such 90th day, to have some or all of
the shares of Voting Stock held by such holder repurchased by the Company at
the Repurchase Price and in the manner set forth in this Article 7th. Any
holder of securities convertible into shares of Voting Stock, or of options,
warrants or rights to acquire shares of Voting Stock, other than the 40%
Shareholder or a transferee of the 40% Shareholder, who converts such
securities or exercises such options, warrants or rights after such an event
and on or prior to the 90th day following the date the notice aforesaid is
mailed, shall have the same right (except as provided below) to have the shares
of Voting Stock to be received upon such conversion or exercise repurchased at
the Repurchase Price. No person shall have any right to have shares of Voting
Stock repurchased by the Company pursuant to this Article (i) if a
determination that the acquisition of shares by the 40% Shareholder is in the
best interests of the Company and its shareholders shall have been expressly
made by a resolution duly adopted by a majority vote of the Disinterested
Directors within 20 days following the date on which the Company receives
credible notice that an Acquiring Person has become a 40% Shareholder (the
"Effective Date"), or (ii) if such repurchase is at the time prohibited by the
general corporate law of the Company's state of incorporation.

     7.2. Notice. If holders of shares of Voting Stock become entitled to have
their shares repurchased as provided in Section 7.1, then not later than 90
days following the Effective Date, the Company shall give written notice, by
first class mail, postage prepaid, at the address shown on the records of the
Company, to each holder of record of shares of Voting Stock other than the 40%
Shareholder (and to any other person known by the Company to have rights to
demand repurchase pursuant to Section 7.1 as of any date on or after the
Effective Date), advising each such holder or other person of the right to have
shares repurchased and the procedures for such repurchase, and setting forth
the Repurchase Price. In the event that the Company fails to give notice as
required by this Section 7.2, any Person entitled to receive such notice may
within twenty days thereafter serve written demand upon the Company to give
such notice. If within twenty days after the receipt of written demand the
Company fails to give the required notice, such Person may at the expense and
on behalf of the Company take reasonable action as may be appropriate to give
notice or to cause notice to be given pursuant to this Section 7.2.

     7.3. Repurchase Price. The Repurchase Price shall be the greater amount
determined by a majority vote of the Disinterested Directors on either of the
following bases, but in no event shall the Repurchase Price be less than the
amount of its involuntary liquidation preference, in the case of preferred
stock, and otherwise the amount of shareholders' equity per share of the
particular class or series as determined in accordance with generally accepted
accounting principles and as reflected in any report published by the Company
or filed with any governmental agency as at the end of the latest fiscal
quarter for which such a report has been published or filed prior to the notice
to shareholders referred to in Section 7.2:

          (i) the highest per share price (including any brokerage commissions,
     transfer taxes, dealer management compensation and soliciting dealers'    
     fees) that can be determined to have been paid by the 40% Shareholder for 
     any shares of Voting Stock of the particular class or series acquired by  
     it at any time; for this purpose, if the consideration paid in any such   
     acquisition of shares by a 40% Shareholder consisted, in whole or in part,
     of consideration other than cash, the Disinterested Directors by a        
     majority vote shall take such action as in their judgment they deem       
     appropriate to establish the cash value of such consideration, but such   
     valuation shall not be less than the cash value, if any, ascribed to such 
     consideration by the 40% Shareholder; and

          (ii) the highest Fair Market Value per share of the particular class 
     or series at any time during the three months prior to the Effective Date.

The determination to be made pursuant to this Section 7.3, when made by the
Disinterested Directors acting in good faith on the basis of such information


and assistance as was then reasonably available for such purpose, shall be
conclusive and binding upon the Company and its shareholders, including any
Person referred to in Section 7.1.

     7.4. Repurchase Agent. If holders of shares of Voting Stock become
entitled to have their shares repurchased as provided in Section 7.1, the Board
of Directors shall designate a Repurchase Agent, which shall be a corporation
or association (i) organized and doing business under the laws of the United
States or any State, (ii) subject to supervision or examination by Federal or
State authority, (iii) having combined capital and surplus of at least
$50,000,000 and (iv) having the power to exercise corporate trust powers.

     7.5. Election to Have Shares Repurchased. For a period of 90 days from the
date of the mailing of the notice, holders of shares of Voting Stock and other
persons entitled to have shares of Voting Stock repurchased pursuant to this
Article 7th may, at their option, deposit certificates representing all or less
than all shares of Voting Stock held of record by them with the Repurchase
Agent together with written notice that the holder elects to have all or a
specified number of such shares repurchased pursuant to this Article 7th.
Repurchase of shares evidenced by certificates deposited in proper form with
the Repurchase Agent shall be deemed to have been effected at the close of
business on the 90th day after the date of the mailing of the notice.

     7.6. Deposit and Payment of Repurchase Price. Promptly after the end of
the 90-day period referred to in Section 7.5, the Company shall deposit in
trust with the Repurchase Agent cash in an amount equal to the aggregate
Repurchase Price of all of the shares of Voting Stock deposited with the
Repurchase Agent for purposes of repurchase. As soon as practicable after
receipt by the Repurchase Agent of the cash deposit, the Repurchase Agent shall
issue checks payable to the order of the persons entitled to receive the
Repurchase Price of the shares of Voting Stock in respect of which such cash
deposit was made.

     7.7. Pro Rata Repurchase. If the Company is unable to repurchase all
shares deposited for repurchase because of limitations upon repurchase
contained in the general corporation law of the Company's state of
incorporation, the Company shall promptly deposit with the Repurchase Agent
cash in the maximum amount which may be used for the repurchase of shares of
Voting Stock. In the event of deposit of less than the full aggregate
Repurchase Price pursuant to the provisions of this Section 7.7, the Repurchase
Agent shall use the amount so deposited to repurchase the deposited shares pro
tanto, in proportion to the Repurchase Price of the shares deposited by each
shareholder for repurchase. Certificates representing all shares which remain
unpurchased shall be returned to the depositors thereof as soon as practicable
thereafter and there shall be no further repurchase rights with respect to such
shares arising in connection with the transactions already completed.

     7.8. Vote Needed to Amend. In addition to any vote required by any other
provisions of law, the Articles or the By-Laws of the Company, the affirmative
vote of the holders of at least a majority of the outstanding Voting Power of
the Voting Stock which is not Beneficially Owned, directly or indirectly, by an
Acquiring Person, shall be required to amend, alter, change or repeal, or adopt
any provision inconsistent with, this Article 7th (including the provisions in
Article 6th which are applicable to this Article 7th), unless such action has
been previously approved by a majority vote of the Disinterested Directors.

     Article 8th. Except as provided in subparagraph B below, no corporate
action of a character described in subparagraph A below, and no agreement, plan
or resolution providing therefor, shall be valid or binding upon the Company
unless such corporate action shall have been approved in compliance with all
applicable provisions of the Business Corporation Law and these Articles and
shall have been authorized by the affirmative vote of at least seventy-five
percent of the outstanding shares of Common Stock entitled to vote, given in
person or by proxy, at a meeting called for such purpose.

8th shall be:

          (b) The Board of Directors shall have approved the transaction prior 
     to consummation thereof upon the vote of not less than a majority         
     disregarding the vote of each director who was an interested person       
     referred to in subparagraph A above, or an affiliate, associate or agent  
     of such interested person, or an associate or agent of any such affiliate.

     Article 9th. The Board of Directors of the Company, when evaluating any
proposal

          (i) involving a tender or exchange offer for any securities of the

economic effect, both immediate and long-term, upon the Company's shareholders,
including shareholders, if any, not to participate in the transaction, and the
social and economic effect on the employees, suppliers and customers of, and
other dealing with, the Company and its subsidiaries and on the communities in
which the Company and its subsidiaries operate or are located. The definitions
set forth in subparagraph C of Article 8th shall apply to this Article 9th.

     Article 10th. Classification of the Board of Directors and Related Matters.

     10.1. Number, Election, etc. The business and affairs of the Company shall
be managed by or under the direction of a Board of Directors comprised as
follows:

          (a) Number. The whole Board of Directors shall consist of such number
     of persons, not less than 5 nor more than 15, as may from time to time be 
     determined by the Board pursuant to a resolution adopted by a majority    
     vote of the Disinterested Directors then in office.

          (b) Classes; Election and Terms. Beginning with the Board of         
     Directors to be elected at the annual meeting of shareholders to be held  
     in 1986, the directors shall be classified in respect of the time for     
     which they shall severally hold office by dividing them into three        
     classes, as nearly equal in number as possible. If the classes of         
     directors are not equal, the Board of 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 meeting after their election; and the term of office of the        
     directors of the third class to expire at the third annual meeting after  
     their election. At each succeeding annual meeting, the shareholders shall 
     elect directors of the class whose term then expires, to hold office until
     the third succeeding annual meeting. Each director shall hold office for  
     the term for which elected and until his or her successor shall be elected
     and shall qualify.

          (c) Removal of Directors. Any directors, any class of directors or   
     the entire Board of Directors may be removed from office by shareholder   
     vote at any time, without assigning any cause, but only if shareholders   
     entitled to cast at least 80% of the votes which all shareholders would be
     entitled to cast at an 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 shareholders may remove a director or     
     directors from office at any time only for cause and only if, in addition 
     to any vote required by any other provision of law, the Articles or the   
     ByLaws of the Company, such removal is approved by the affirmative vote of
     at least a majority of the Voting Power of the outstanding shares of


     Voting Stock of the Company which are not Beneficially Owned by an        
     Acquiring Person..

          (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.

          (e) Nominations of Director Candidates. Nominations for the election 
     of directors may be made only by the Board of Directors or a committee    
     appointed by the Board of Directors or by any holder of record of stock   
     entitled to vote in the election of the directors to be elected; but a    
     nomination may be made by a shareholder only if written notice of such    
     nomination has been given, either by personal delivery or by United States
     mail, postage prepaid, to the Secretary of the Company not later than 90  
     days in advance of the meeting at which the election is to be held. Each  
     such notice shall set forth: (a) the name and address of the shareholder  
     who intends to make the nomination and of the person or persons to be     
     nominated; (b) a representation that the shareholder is a holder of record
     of stock of the Company entitled to vote at such meeting and intends to   
     appear in person or by proxy at the meeting to nominate the person or     
     persons specified in the notice; (c) a description of all arrangements or 
     understandings between the shareholder and each nominee and any other     
     person or persons (naming such person or persons) pursuant to which the   
     nomination or nominations are to be made by the shareholder; (d) such     
     other information regarding each nominee proposed by such shareholder as  
     would be required to be included in a proxy statement filed pursuant to   
     the proxy rules of the Securities and Exchange Commission, had the nominee
     been nominated by the Board of Directors; and (e) the consent of each     
     nominee to serve as a director of the Company if so elected.

          (f) Exception for Directors Elected by Preferred Stock. Whenever the 
     holders of any class or series of stock having a preference over the      
     Common Stock of the Company as to dividends or assets shall have the      
     right, voting separately as a class, to elect one or more directors of the
     Company, none of the foregoing provisions of this Section 10.1 shall apply
     with respect to the director or directors elected by such holders of      
     preferred stock.

     10.2. Vote Needed to Amend. In addition to any vote required by any other
provisions of law, the Articles or the By-Laws of the Company, the affirmative
vote of the holders of at least a majority of the Voting Power of the Voting
Stock of the Company which is not Beneficially Owned, directly or indirectly,
by an Acquiring Person, shall be required to amend, alter, change or repeal, or
adopt any provision inconsistent with, this Article 10th (including the
provisions in Article 6th which are applicable to this Article 10th), unless
such action has been previously approved by a majority vote of the
Disinterested Directors.

     Article 11th. Extraordinary Vote for Business Combinations.

     11.1. Votes Required. In addition to any vote required by any other
provisions of law, the Articles or the By-Laws of the Company, the affirmative
vote of the holders of at least a majority of the Voting Power of the Voting
Stock of the Company which is not Beneficially Owned by an Acquiring Person
shall be required for the approval or authorization of (i) any Business
Combination or (ii) any proposal to amend, alter, change or repeal, or adopt
any provision inconsistent with, this Article 11th (including the provisions
in Article 6th which are applicable to this Article 11th); provided, however,
that the foregoing voting requirements shall not be applicable if the Board of
Directors of the Company shall have approved the Business Combination or

                                                           EXHIBIT 10(a)
                       MINE SAFETY APPLIANCES COMPANY

             1990 NON-EMPLOYEE DIRECTORS' STOCK OPTION PLAN

                       (As amended April 27, 1994)

     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 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 are to be granted, the timing of such grants, the number of shares
subject to any stock option, the exercise price of any stock option, the
periods during which any stock option may be exercised 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 may be made under the Plan is 50,000 shares of the Common
Stock, without par value, of the Company (the "Common Stock"), subject to
adjustment and substitution as set forth in Section 5.  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.  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

     On the third business day following the day of each annual meeting of the
shareholders of the Company, 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 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 500 shares of Common Stock, subject to
adjustment and substitution as set forth in Section 5.  If the number of shares
then remaining available for the grant of stock options under the Plan is not
sufficient for each non-employee Director to be granted an option for 500
shares (or the number of adjusted or substituted shares pursuant to Section 5),
then each non-employee Director shall be granted an option for a number of
whole shares equal to the number of shares then remaining available divided by
the number of non-employee Directors, 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 date of grant, determined as provided in Section 4(G).  


         (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, determined as provided in Section 4(G), 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 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 as
      provided in Section 4(E).  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 date of grant.  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)  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 (but only to the extent 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 two years after
            the date the grantee ceases to be a Director, whichever is the
            shorter period, provided that, in the case of a grantee who is
            disabled within the meaning of Section 22(e)(3) of the Code (a
            "Disabled Grantee"), any then outstanding stock option shall be
            exercisable in full whether or not exercisable by the grantee
            immediately prior to ceasing to be a Director;

              (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 two years after the date of death, whichever is
            the shorter period;

              (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) at any time prior to
            the expiration date of such stock option or within one year after
            the date of death, whichever is the shorter period.

              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).
            Whether a grantee is a Disabled Grantee shall be determined, in its
            discretion, by the Committee, and any such determination by the
            Committee shall be final and binding.

         (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)  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 (or on any composite index
     including) the principal United States securities exchange registered
     under the Securities Exchange Act of 1934 (the "1934 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 Section  
     4(G).  If the fair market value of the Common Stock cannot be determined   
     on the basis previously set forth in this Section 4(G) 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.

        (H)  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

                  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 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.

     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, 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, the number and kind of shares of stock or
other securities into which each outstanding share of the Common Stock shall be
so changed or for which each such share shall be exchangeable.

     In case of any adjustment or substitution as provided for in this Section
5, 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 5 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.  


                             SECTION 6

      Effect of the Plan on the Rights of Company and Shareholders

     Nothing in the Plan, in any stock option granted under the Plan, or in any
stock option 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 7

                        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 1934 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, (b) amend more than once
every six months the provisions of the Plan relating to the selection of the
Directors to whom stock options are to be granted, the timing of such grants,
the number of shares subject to any stock option, the exercise price of any
stock option, the periods during which any stock option may be exercised and
the term of any stock option other than to comport with changes in the Code or
the rules and regulations thereunder or (c) otherwise amend the Plan in any
manner that would cause stock



options 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 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 agreement, the Board shall have the
power to amend the Plan in any manner deemed necessary or advisable for stock
options 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
1934 Act), and any such amendment shall, to the extent deemed necessary or
advisable by the Board, be applicable to any outstanding stock options
theretofore granted under the Plan notwithstanding any contrary provisions
contained in any stock option agreement.  In the event of any such amendment to
the Plan, the holder of any stock option outstanding under the Plan shall, upon
request of the Committee and as a condition to the exercisability of such
option, execute a conforming amendment in the form prescribed by the Committee
to the stock option agreement referred to in Section 4(F) within such
reasonable time as the Committee shall specify in such request.  


                             SECTION 8

                   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 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.  

    
                                                              EXHIBIT 10(b)

    providing life insurance benefits for their families and dependents
    during their working career with the Company and to provide them
    with additional flexibility and post-employment benefits upon their
    retirement from active employment with the Company.  This result is
    to be accomplished by substituting, for eligible employees, all but
    $50,000 of group term life insurance with permanent life insurance. 
    The major portion of the premium cost will be paid by the Company
    and the balance will be paid by the Participant.

         The following definitions shall apply for purposes of the Plan
    unless another meaning is clearly required by the context.

         "Beneficiary" shall mean any person, persons or entity who or

    of a Participant.  A portion of the Death Benefit, referred to as
    the "Insurance Amount" (as listed in the "Table of Insurance
    Amounts" attached hereto), will be paid to the Participant's
    Beneficiaries and the balance paid to the Company.

    provided to executives who are selected for participation after the
    effective date of the Plan shall be in an amount determined by the
    President 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

    rates, or acceptance by the Company of an offer of insurance made
    by the Insurer at non-standard rates.

    Section 5 - Payment for Coverage

             The cost of the applicable amount of life insurance shall
    be borne jointly by the Company and the Participant as follows.

             The Company shall pay, not later than the due date
    therefor (including any "grace period"), the gross amount of
    
    premium due under each Policy issued to fund the benefits of the
    Plan.  Thereafter, each Participant shall reimburse the Company, by
    direct payment in cash or through payroll deduction, an amount
    equal to the Imputed Cost of Benefit ("ICOB").  The ICOB shall be
    determined by multiplying the Participant's Insurance Amount
    (expressed in one thousand dollar increments) by the "Unit Price"
    determined pursuant to "Table of Unit Values" attached hereto,
    based upon the age of the Participant as of the Policy anniversary
    date.  Alternatively, there shall be substituted for the applicable
    Unit Price, the Insurer's initial issue, one-year term insurance
    standard risk rate, but only if such rate is lower than the
    otherwise applicable Unit Price.

    Section 6 - Payment of Proceeds Upon Death Prior to Retirement

             In the event of the death of the Participant prior to his
    retirement from 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

             On or before the date on which a Participant becomes a
    Retired Participant, he shall be given the right to elect one of
    the following options with respect to his Insurance Amount.

             (1)  Maintain the Existing Arrangement.  Under this
    option the Executive Insurance Program would remain as it existed
    prior to the Participant's retirement except that the Retired
    Participant will not be required to reimburse the Company for any
    cost associated with the post-retirement coverage.  For federal
    income tax purposes, however, a Retired Participant will be deemed
    
    to have received taxable income equal to the "Imputed Cost of
    Benefit" described in Section 5, 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 not imputed "cost of benefit" 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 Retired 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. 
    Payment of the supplemental retirement benefits shall be made in a
    series of approximately equal monthly payments over a period of 15
    years.

             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
    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.

    
    Section 8 - 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.

    Section 9 - 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.

             (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 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.
