MINE SAFETY APPLIANCES COMPANY MANAGEMENT'S DISCUSSION AND ANALYSIS Sales have grown in most markets, although at a lesser pace in recent months. Commercial sales from U.S. operations have increased this year compared to 1994, but less so in the third quarter. Shipments of gas masks to the U.S. military have continued below prior-year levels as expected. Instruments (particularly permanently installed equipment), chemical specialty products and exports of most products have shown robust growth. International sales also have continued to grow worldwide. U.S. commercial safety products sales have shown mixed results. Business to nuclear power plants has been seriously affected by the reduced usage of respirators following interpretations of studies concerning worker productivity. This has particularly impacted the registrant due to a very high historic market share in this industry. A more recent scientific study has cast new light on worker productivity and respirator use, which may eventually reverse the sales trend. Sales to government and civilian environmental remediation projects have been affected by delays in government funding of such activities, although the need continues to be significant. Sales of self-contained breathing apparatus, particularly to the fire service, and of protective helmets have been strong. The decline in net income in the third quarter compared to the same period of the prior year is due to two factors. The third quarter of 1994 included the LIFO accounting effect of U.S. manufacturing inventory reductions which increased net income by $1,200,000 or 20 cents per share. The third quarter of 1995 includes charges to net income of $575,000 or 10 cents per share, stemming from the restructuring of a South African affiliate, Boart-MSA. The registrant has a minority position in the ownership and management control of this venture. Boart-MSA had a joint venture, Natfire, which was unsuccessful and was reorganized in 1995. The third-quarter charges relate to prior-period losses and the reorganization of Natfire. The profitability of U.S. operations has improved due to somewhat higher sales and increased productivity. Brazilian operations have also made a significant contribution to the corporate earnings improvement as a result of local economic reforms. Other areas of strength were Chile, France, China, Southeast Asia and the Middle East. Improvements were also noted in Italy, Spain and Sweden. Efforts continue in the important task of increasing profitability in Europe. Earnings per share have also benefitted from an ongoing share repurchase program. The decrease in quarterly earnings was disappointing as the abovementioned unusual items could not be overcome by general improvement. The current environment presents a varied mixture of opportunities and challenges. In product innovation, availability of delivery and cost competitiveness, the registrant has made considerable progress. General improvements in the world economy that may come after a recent sluggish period in the U.S. could be of help to the registrant. The registrant has seen a number of areas of vigorous growth this year, which probably represent an increase in market share. Operating costs in most areas have been well managed. One challenge is that a significant part of this growth has come in product and market areas that have been historically volatile. These areas might not be such overachievers in future months. A more significant challenge is dealing with negative movements in nuclear power and environmental remediation markets, which can only be overcome by generating increased business elsewhere and improving productivity. The national needs for environmental work and a settling of the Federal budget conflict, hopefully, should generate recovery in funding for customers in the military and civilian remediation markets. Turning around the nuclear power plant sales situation will be a longer-term project. Comparative foreign currency exchange losses charged to income are as follows:

Brazilian governmental economic reforms in 1994 have had significant impact on the comparative third quarter and year to date currency exchange gains and losses. Currency exchange adjustments charged directly to the equity cumulative translation adjustments account are shown below. Significant third quarter 1995 losses relate to Germany and Japan; year to date translation gains relate to Germany and Netherlands. Significant third quarter 1994 gains relate to Germany and Britain; year to date translation gains relate to Germany and Australia.

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 September 30, 1995 were 3.6 and 6.0%, respectively, as compared to 3.4 and 7.5% at December 31, 1994.

*  Note:  References in the By-Laws to the "Restated Articles" are to the 
Articles of the Corporation as amended by resolutions adopted at the Annual 
Meeting of shareholders on May 23, 1986, and as they may be thereafter amended 
or

supplemented.  Section references in brackets are to specific provisions of 
the Restated Articles, and indicate that the preceding provision is taken 
substantially verbatim from the Restated Articles; and capitalized terms are 
used as those terms are defined in the Restated Articles.

          Section 1.02.  Business at Annual Meetings.  The business at an 

annual meeting of shareholders shall include:  (a) a review of the business of 

the preceding year; (b) the election of directors to succeed those whose terms 

shall expire; (c) the selection of auditors; and (d) such other business as may

properly be brought before the meeting.  No business may be transacted at any

of meeting (or any supplement thereto) and matters which are incidental or 

germane thereto, (ii) matters otherwise properly brought before the meeting by

or at the direction of the Board of Directors, and (iii) matters properly 

brought before the meeting by a shareholders, but only in accordance and upon

compliance with the provisions of the proxy rules of the Securities and Exchange

Commission relating to shareholder proposals.  If for any reason the annual

meeting is not held at the time fixed therefor, the 

election of directors may be held at a subsequent meeting called for that 

purpose.

          Section 1.03.  Special Meetings.  Except as otherwise 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 shareholders other than that the general 

nature of which has been stated in the notice of meeting, and business which is

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 shareholders' 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 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 forgoing 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 shareholders 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 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 radiogram,

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.

                              ARTICLE II

                              Directors

          Section 2.01.  Number, Election, etc.

                (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.  [Restated Articles Section 10.1(a)]


          (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.

[Restated Articles Section 10.1(b)]

          (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 By-Laws 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  [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

Section 10.1(d)]

          (e) Nomination 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.  [Restated Articles Section 10.1(e)]

          (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 2.01 shall apply with respect 

to the director or directors elected by such holders of preferred stock.  

[Restated Articles Section 10.1(f)]

          (g) In case of a vacancy in the office of any director elected 

by the preferred stock, the remaining directors or director elected by the 

preferred stock may choose a successor who shall hold office for the unexpired 

term in respect of which such vacancy occurred.

          (h) Each director shall hold office from the time of his 

election, but shall be responsible as a director from such time only if he 

consents to his election; otherwise from the time he accepts office or attends

for the ensuing year, and may transact any other business.  Notice of the

of Directors from time to time, or if not so designated, as determined by the

not be required to be given, except as otherwise expressly required herein or by

law, except that whenever the time or place of regular meetings shall be 

initially fixed or changed, notice of such action shall be given promptly by

telephone or otherwise to each director not participating in such action.  Any

the meeting, or if not so specified by the Secretary.  Notice of every special 

meeting of the Board of Directors, which states the place, day and hour thereof,

shall be given to each director either by being mailed on at least the second

calendar day prior to the date of the meeting, or by being sent by telex or 

telegraph or given personally or by telephone prior to the date of the meeting.

Neither the call of a special meeting nor the notice thereof 

need specify the purpose thereof or the business to be transacted thereat, 

except as otherwise expressly required herein or by law.

          Section 2.05.  Quorum.  At all meetings of the Board of Directors, the

presence or participation by other lawful means of a majority of the directors 

in office shall be necessary and sufficient to constitute a quorum for the

transaction of business.  The Directors present at a duly organized meeting 

shall continue to constitute a quorum until adjournment, notwithstanding the 

withdrawal of enough Directors to leave less than a majority.  If a quorum is

not present at any meeting, the meeting may be adjourned from time to time by a

majority of directors present, without notice other than announcement at the

meeting, until a quorum as aforesaid shall be present.

          Section 2.06.  Action.  Resolutions of the Board shall be adopted, and

present at a meeting duly organized, except as otherwise provided herein, in the

Restated Articles or by law.  The Chairman, or in his absence the President,

shall preside at all meetings of the Board of Directors.  The Secretary shall

take the minutes at all meetings of the Board.  In the absence of the forgoing

officers the Directors present shall select a member of the Board to preside;

and in the absence of the Secretary, the presiding officer shall designate any

person to take the minutes of the meeting.  The yeas and nays shall be taken and

recorded in the minutes at the request of any director present at a meeting.

the Directors may participate in any regular or special meeting of the Board or 

of a committee of the Board by means of conference telephone or similar 

communications equipment by means of which all persons participating in the

meeting are able to hear each other, or by any other lawful means in lieu of

attendance, any may act by proxy to the extent at the time permitted by law.

All directors so participating shall be deemed present at the meeting.

          Section 2.08.  Emergency Provisions.  Notwithstanding any other 

provisions of law, the Articles or these By-Laws, during any emergency period

caused by war or any other national catastrophe or local disaster of sufficient

severity to prevent the conduct and management of the business and affairs of

the Company by its Board of Directors and officers as contemplated by the other 

provisions of these By-Laws, a majority of the available Directors (or the sole 

such Director) who have not been rendered incapable of acting because of 

incapacity or the difficulty of communication or transportation to the place of

meeting shall constitute a quorum for the sole purpose of electing Directors to

fill such vacancies or to reduce the size of the full Board or both; and a 

majority of the directors (or the sole survivor) present at such a meeting may

take such action. Directors so elected shall serve until the absent Directors 

are able to attend meetings or until the shareholders act to elect Directors to

succeed them.  During such an emergency period, if both the Board and the Exec-

utive Committee are unable or fail to meet, any action appropriate to the 

circumstances may be taken by such officers of the Company as may be present and

able.

Questions as to the existence of a national catastrophe or local disaster and

the number of surviving members capable of acting shall be conclusively

determined at the time by the Directors or the officers so acting.

          Section 2.09.  Presumption of Assent.  Minutes of each meeting of the 

Board shall be made available to each director at or before the next succeeding 

regular meeting.  Every director shall be presumed to have assented to such 

minutes unless his objection thereto shall be made to the Secretary within two 

days after such next regular meeting.

          Section 2.10.  Resignations.  Any director may resign by submitting to

the Chairman of the Board or the President his resignation, which (unless other-

wise specified therein) need not be accepted to make it effective and shall be 

effective immediately upon its receipt by such officer.

          Section 2.11.  Committees.  

          (a) Appointments; Powers.  Except as otherwise provided in 

subsection (b) pertaining to the Executive 

Committee, standing or temporary committees shall consist of one or more 

Directors of the Company and such other members, who need not be directors, as

the Board may direct and may be appointed from time to time by a majority of the

Directors present or participating at any regular or special meeting.  The Board

may from time to time invest committees with such power and authority, subject 

to such conditions as it may see fit, except that no committee shall have any

power or authority to adopt, amend or repeal any By-Law.

          (b) Executive Committee.  An Executive Committee of three or 

more directors may be appointed by resolution adopted by a majority of the

directors in office; it shall have all the powers and exercise all of the

authority of the Board during intervals between meetings, except as specially

limited by the Board.  Meetings of the Executive Committee may be called at any 

time by any member, to be held at such place and day and hour as shall be 

specified by the person or persons calling the meeting, or if not so specified

by the Secretary.  Notice of every meeting of the Executive Committee, which

states the place, day and hour thereof, but need not state the purposes thereof,

shall be given to each 

member either by being mailed on at least the second calendar day prior to the

date of the meeting, or by being sent by telegraph or given personally or by

telephone prior to the date of the meeting.  The presence or particiation by 

other lawful means of a majority of the members of the Committee shall be 

necessary and sufficient to constitute a quorum for the transaction of business,

and any action of the Committee upon any matter shall be taken and be valid with

the affirmative vote of at least a majority of the members of the Committee.

The Executive Committee shall keep a record of all action taken and report such

action to the Board of Directors at its next meeting thereafter.

          (c) Term; Vacancies; Absence or Disqualification.  All committee

members appointed by the Board shall serve during the pleasure of the Board,

which may fill vacancies and may designate one or more Directors as alternate

members of any committee, to take the place of any absent or disqualified member

at any meeting.  In the absence or disqualification of any member or alternate 

member of any committee or committees, the member or members thereof partici-

pating at any meeting and not disqualified from 

voting, whether or not he, she or they constitute a quorum, may unanimously

appoint another Director to act at the meeting in the place of any such absent 

or disqualified member or alternate member.

          (d) Organization; Finality of Action.  All committees shall keep 

such record of the transactions of their meetings as the Board or these By-Laws 

shall direct.  All committees shall determine their own organization, procedures

and times and places of meeting, unless otherwise directed by the Board and

except as otherwise provided in these By-Laws.  Any action taken by any 

committee shall be subject to alteration or revocation by the Board; provided, 

however, that third parties shall not be prejudiced by such alteration or

revocation.

          Section 2.12.  Compensation.  By resolution of the Board, Directors 

may be paid a fixed sum and expenses, if any, of attendance for any regular or 

special meeting of the Board or any committee, and may in addition be paid an

annual retainer fee or a retirement allowance, or both.  Directors shall also be

entitled to receive such 

compensation for services rendered to the Company as officers, committee 

members, or in any capacity other than as directors, as may be provided from 

time to time by resolution of the Board.  [Amended by Board of Directors

                              ARTICLE VII

                            Indemnification

                    [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 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.

          (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

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

hereafter created, to which any indemnitee may be entitled under any agreement

or by-law, charter provision, vote of shareholders 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 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

4/24/87.]

[Approved by Shareholders 4/24/87.]  [Restated Articles, Article 14th.]

          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
