day prior to the  annual  meeting  and not later  than the later of the 60th day

notice as described above. A shareholder's notice shall set forth (A) as to each
person whom the shareholder proposes to nominate for election or reelection as a
director,  all  information  relating  to such  person  that is  required  to be

description  of the  business  desired to be brought  before  the  meeting,  the

2.12 to the contrary, in the event that the number of directors to be elected to
the Board of Directors  of the  Corporation  at the annual  meeting is increased
pursuant to an act of the Board of Directors of the  Corporation and there is no
public  announcement by the Corporation  naming all of the nominees for director
or specifying the size of the increased Board of Directors on or before the date
which is 15 days before the latest date by which a shareholder may timely notify
the  Corporation of nominations or other business to be brought by a shareholder
in  accordance  with  paragraph  (a)(ii) of this Section  2.12, a  shareholder's
notice required by this Section 2.12 shall also be considered  timely,  but only
with respect to nominees for any new positions  created by such increase,  if it
shall be received by the  Secretary at the  principal  executive  offices of the
Corporation  not later than the 15th day  following the day on which such public
announcement is first made by the Corporation.

         (B)  SPECIAL  MEETINGS OF  SHAREHOLDERS.  Only such  business  shall be

persons for election to the Board of Directors may be made at a special  meeting
of  shareholders  at  which  directors  are  to  be  elected   pursuant  to  the
Corporation's  notice  of  meeting  (i) by or at the  direction  of the Board of
Directors or (ii)  provided  that the Board of  Directors  has  determined  that
directors  shall  be  elected  at  such  meeting,  by  any  shareholder  of  the
Corporation  who is a  shareholder  of  record  at the time of  giving of notice
provided for in this paragraph (b), who shall be entitled to vote at the meeting
and who complies with the notice  procedures set forth in this paragraph (b). In
the event  the  Corporation  calls a special  meeting  of  shareholders  for the
purpose of electing one or more  directors to the Board of  Directors,  any such
shareholder may nominate a person or persons (as the case may be), for election


                                       5

the  later  of the  60th  day  prior  to such  special  meeting  or the 15th day
following the day on which public  announcement is first made of the date of the
special  meeting and of the  nominees  proposed by the Board of  Directors to be
elected  at such  meeting.  In no event  shall  the  public  announcement  of an
adjournment or postponement of a special meeting  commence a new time period for
the giving of a shareholder's notice as described above.

procedures  set  forth  in this  Section  2.12  shall  be  eligible  to serve as
directors and only such business shall be conducted at a meeting of shareholders
as shall have been brought before the meeting in accordance  with the procedures
set  forth in this  Section  2.12.  Except as  otherwise  provided  by law,  the
Certificate of Incorporation or these bylaws,  the Chairman of the meeting shall
have the  power  and duty to  determine  whether a  nomination  or any  business
proposed to be brought before the meeting was made or proposed,  as the case may
be, in accordance with the procedures set forth in this Section 2.12 and, if any
proposed  nomination or business is not in compliance with this Section 2.12, to
declare that such defective proposal or nomination shall be disregarded.

mean  disclosure  in a press  release  reported  by the Dow Jones News  Service,
Associated Press or comparable  national news service or in a document  publicly
filed by the Corporation with the Securities and Exchange Commission pursuant to
Section 13, 14 or 15(d) of the Exchange Act.

         (iii) If the  Corporation  is  required  under  Rule  14a-8  under  the
Exchange Act to include a shareholder's  proposal in its proxy  statement,  such
shareholder  shall be deemed to have given  timely  notice for  purposes of this
Section 2.12 with respect to such proposal.

         Nothing  in this  Section  2.12 shall be deemed to affect any rights of
the holders of any series of Preferred Stock to elect directors.

     Section 3.1  BOARD OF DIRECTORS, NUMBER, QUALIFICATION,
                  ELECTIONS, TERM OF OFFICE AND COMPENSATION:
                  -------------------------------------------

         The business and affairs of the Corporation shall be managed by a Board
of not less than five (5) nor more than fifteen (15) Directors,  as may be fixed
from time to time by the vote of a majority of the whole Board.  Directors shall
be of full age, but need not be residents of Pennsylvania or shareholders of the
Corporation.

         Any  nominee for any  vacancy on the Board of  Directors  which has not
been  proposed  by this  Board of  Directors  or by the  Nomination  and  Search
Committee  of this  Board  may be  proposed  by a  nominator  only  if (i)  such
nominator is a shareholder of this corporation, (ii) such nominator supplies the
Nomination and Search Committee with such information  concerning such candidate
or candidates as would be required to be included in the form of proxy statement
filed with the Securities and Exchange  Commission with respect to such nominee,
(iii) the  foregoing  is sent to the  attention  of the  Nomination  and  Search
Committee, c/o the Secretary of the Corporation,  at least 120 days prior to the
date of the meeting at which such  nominee,  if permitted to stand for election,
would be voted  upon by the  shareholders  of this  Corporation,  and (iv)  such
proposed  nominee has been  approved to stand for  election by a majority of the
members of the Nomination and Search Committee and by a majority of the Board of
Directors of this  Corporation,  which  approval does not require that he be the
only  nominee for a  particular  vacancy and does not require that such Board or
Committee recommend his election to such vacancy.

         The  Directors,  other than any who may be  elected  by the  holders of
shares of any class or series of stock  entitled to elect  Directors  separately
pursuant to the terms of Articles Fifth of the Articles of  Incorporation or any
resolution  or  resolutions  providing for the issuance of such stock adopted by
the Board of Directors shall be classified,  with respect to the duration of the
term for which they severally hold office, into three classes as nearly equal as
possible (each,  individually a "Three Year Class",  and collectively the "Three
Year  Classes").  Such  Three Year  Class  which  shall be elected at the Annual
Meeting of  Shareholders  held in 1993 for a term expiring at the Annual Meeting
of  Shareholders to be held in 1996 shall be designated as "Class A"; the second
Three Year Class to be elected  at the Annual  Meeting of  Shareholders  held in
1994 for a term  expiring at the Annual  Meeting of  Shareholders  to be held in
1997 shall be  designated  as "Class  B";  and the third  Three Year Class to be
elected at the Annual Meeting of  Shareholders  held in 1995 for a term expiring
at the Annual Meeting of  Shareholders to be held in 1998 shall be designated as
"Class C". The Board of  Directors  shall  increase  or  decrease  the number of
Directors in one or more classes as may be appropriate  whenever it increases or
decreases  the number of  Directors  pursuant to this  Section  3.1, in order to
ensure that the three Three Year  Classes  shall be as nearly equal in number of
possible. At each Annual Meeting of Shareholders, the successors of the class of
Directors whose term expires at that meeting shall be elected to hold office for
a term  expiring at the Annual  Meeting of  Shareholders  held in the third year
following the year of their election.

                                       7




         The Board of Directors shall have the authority to fix the compensation
of  Directors  for their  services  and to  authorize  payment  for  expenses of
attendance at meetings. A Director may also be a salaried officer or employee of
the Corporation.

         The Board of Directors  may elect a Chairman who shall,  when  present,
preside  at all  meetings  of the  Board of  Directors  and at all  meetings  of
shareholders. The Chairman may appoint another member of the Board to preside in
his absence.

Directors present at a meeting at which a quorum is present shall be the acts of
the Board of Directors.  A Director who is present at a meeting shall be counted
in  determining  the presence of a quorum even though a contract or  transaction
between the  Corporation  and such  Director  or another  business in which such
Director has a financial interest is authorized at the meeting.

     Section 3.3 DIRECTORS' CONSENT IN LIEU OF MEETING:
                 -------------------------------------

         Any action which may be taken at a meeting of the Board of Directors or
of any Committee thereof may be taken without a meeting if a consent or consents
in  writing,  setting  forth the action so taken,  shall be signed by all of the
Directors  or the  members  of the  Committee,  as the case may be, and shall be
filed  with  the  Secretary  of the  Corporation.  One  or  more  Directors  may
participate  in a meeting of the Board of  Directors  or a Committee  thereof by
means of a conference telephone or similar communications  equipment by means of
which all persons participating in such meeting can hear each other.

remainder of the full term of the class of  Directors in which the  directorship
was created or the vacancy  occurred and until such  Director's  successor shall

harmless  to the  fullest  extent  permitted  under  the  Pennsylvania  Business
Corporation  Law, the Directors'  Liability Act (the "DLA") and other applicable
law, as such laws  existed on the date this Section 7.1 was adopted by the Board
Of Directors or, except as provided in Section 7.1(f)  hereof,  as such laws may
thereafter by amended  ("Pennsylvania Law"), any person who was or is a party or
was or is threatened to be made a party to any threatened,  pending or completed
action,  suit  or  proceeding,   whether  civil,  criminal,   administrative  or
investigative,  including,  without limitation,  an action by or in the right of
the Corporation (collectively,  for purposes of this Section 7.1 and Section 7.2
hereof, "Proceeding"),  by reason of the fact that he is or was or has agreed to
become a director  or officer of the  Corporation,  or is or was  serving or has
agreed to serve at the  request of the  Corporation  as a director or officer of
another corporation,  or if a director or officer of the Corporation,  is or was
serving or has agreed to serve at the request of the  Corporation as an employee
or agent of another  corporation,  partnership,  joint  venture,  trust or other
enterprise,  or by reason of any action alleged to have been taken or omitted in
any such  capacity,  and may indemnify  and hold harmless to the fullest  extent
permitted under  Pennsylvania  Law any person who was or is a party or was or is
threatened to be made a party to such a Proceeding by reason of the fact that he
is or was or has agreed to become an employee or agent of the  Corporation,  or,
if any employee or agent of the Corporation,  is or was serving or has agreed to
serve at the  request  of the  Corporation  as an  employee  or agent of another
corporation,  partnership,  joint venture,  trust or other  enterprise,  against
expenses, liability and loss (including, without limitation, attorneys' fees and
disbursements,  punitive and other damages,  judgments, fines, penalties, excise
taxes assessed with respect to an employee  benefit plan,  amounts paid or to be
paid in  settlement  and costs and  expenses of any  nature)  incurred by him in
connection with such Proceeding and any appeal  therefrom:  PROVIDED,  that such
indemnification  shall not be made in any case  where the act or  failure to act
giving  rise to the  claim for  indemnification  is  determined  by a court in a
final,   binding   adjudication  to  have  constituted   willful  misconduct  or
recklessness.


                                       16



         (b) The  Corporation  may  indemnify  and hold  harmless to the fullest
extent permitted under  Pennsylvania Law any person who was or is a party or was
or is threatened to be made a party to any  Proceeding,  by reason of any of his
actions  in a  non-official  capacity  while  serving  as a  director,  officer,
employee  or agent of the  Corporation,  against  expenses,  liability  and loss
including, without limitation,  attorneys' fees and disbursements,  punitive and
other damages,  judgments,  fines, penalties, excise taxes assessed with respect
to an employee benefit plan,  amounts paid or to be paid in settlement and costs
and expenses of any nature  incurred by him in connection  with such  Proceeding

in any case  where  the act or  failure  to act  giving  rise to the  claim  for
indemnification  is determined by a court in a final,  binding  adjudication  to
have constituted willful misconduct or recklessness.

         (c) The termination of any Proceeding by judgment,  order,  settlement,
conviction,  or upon a plea of guilty  or NOLO  CONTENDERE,  or its  equivalent,
shall not, of itself, create a presumption that the persons' conduct constituted
willful misconduct or recklessness.

         (d)  Expenses  incurred  by  a  director  or  officer  in  defending  a
Proceeding shall be paid by the Corporation in advance of the final  disposition
of the Proceeding,  provided that, if Pennsylvania Law requires,  the payment of
such expenses  shall be made only upon receipt of an undertaking by or on behalf
of the  director  or  officer  to repay such  amount if it shall  ultimately  be
determined  that he is not  entitled to be  indemnified  by the  Corporation  as
mandated in this Section 7.1 or otherwise.  Expenses incurred by other employees
and agents may be so paid to the extent provided by the Board of Directors, upon
receipt of the foregoing undertaking by or on behalf of the employee or agent.

         (e) The  indemnification  provided  by this  Section  7.1  shall  be in
addition  to and not  exclusive  of any  other  rights  to which  those  seeking
indemnification  may be entitled  under  Pennsylvania  Law, or under any By-Law,
agreement  executed by the  Corporation,  insurance  policy,  fund of any nature
established by the Corporation,  vote of shareholders or disinterested directors
or otherwise.  The indemnification so provided by this Section 7.1 or otherwise,
may be granted whether or not the Corporation  would have the power to indemnify
such person under any provision of Pennsylvania Law other than the DLA.

         (f) The indemnification provisions of this Section 7.1 shall constitute
a  contract  between  the  Corporation  and  each  of its  directors,  officers,
employees and agents who are or may be entitled to indemnification hereunder and
who serve in any such capacity at any time while such  provisions are in effect.
Any appeal or modification of the indemnification provisions of this Section 7.1
shall not limit any such  person's  rights  to  indemnification  (including  the
advancement  of  expenses)  then  existing  or arising  out of  events,  acts or
omissions  occurring prior to such repeal or  modification,  including,  without
limitation,  the right to indemnification with respect to Proceedings  commenced
after such repeal or modification based in whole or in part upon any such event,
act or omission.

         (g) The  Corporation  may create a fund of any nature,  which may,  but
need not be, under the control of a trustee,  or otherwise  may secure or insure
in any manner its indemnification obligations, whether arising under or pursuant
to this Section 7.1 or otherwise.

                                       18



         (h) The Corporation  may purchase and maintain  insurance to insure its
indemnification  obligations on behalf of any person who is or was or has agreed
to become a director,  officer,  employee or agent of the Corporation,  or is or
was serving at the request of the Corporation as a director,  officer,  employee
or agent of another  corporation,  partnership,  joint  venture,  trust or other
enterprise,  against any  expense,  liability or loss  asserted  against him and
incurred  by him or on his behalf in any such  capacity,  or arising  out of his
status as such, whether or not the Corporation would have the power to indemnify
him against such liability under the provisions of this Section 7.1 or under any
provision of Pennsylvania Law other than the DLA.

         (i) The indemnification  provided by this Section 7.1 shall continue as
to a person  who has ceased to be a  director,  officer,  employee  or agent and
shall inure to the benefit of the heirs,  executors and administrators of such a
person.

         (j) If Section 7.1 or any portion  thereof shall be  invalidated on any
ground  by any  court of  competent  jurisdiction,  then the  Corporation  shall
nevertheless indemnify each director or officer, and may indemnify each employee
or agent of the  Corporation,  as to expenses,  liability  and loss  (including,
without  limitation,  attorneys'  fees and  disbursements,  punitive  and  other
damages,  judgments,  fines, penalties, excise taxes assessed with respect to an
employee  benefit plan,  amounts paid or to be paid in settlement  and costs and
expenses  of any  nature)  incurred by him in  connection  with any  Proceeding,
including an action by or in the right of the Corporation, to the fullest extent
permitted by any applicable portion of this Section 7.1 that shall not have been
invalidated and to the fullest extent permitted by applicable law.

     Section 7.2 LIMITATION ON DIRECTORS' PERSONAL LIABILITY:
                 -------------------------------------------

         (a) To the fullest extent permitted under the DLA, as it existed on the
date this Section 7.2 was adopted or, except as provided in  subsection  7.2(e),
as such law may thereafter be amended,  a director of this Corporation shall not
be personally  liable for monetary  damages as a result of any action or failure
to act unless  both:  (1) the  director  has  breached  or failed to perform the
duties  of his  office  under  Section  8363 of the DLA:  and (2) the  breach or
failure to perform constitutes self-dealing, willful misconduct or recklessness.

         (b) The  provisions  of this  Section  7.2 shall not apply to:  (1) the
responsibility or liability of a director  pursuant to any criminal statute:  or
(2) the  liability  of a director  for the  payment of taxes  pursuant to local,
state or federal law.

         (c) The termination of any Proceeding by judgment,  order,  settlement,
conviction,  or upon a plea of guilty  or NOLO  CONTENDERE,  or its  equivalent,
shall not, of itself,  create a presumption that the director breached or failed
to perform the duties of his office  under  Section 8363 of the DLA and that the
breach or failure to perform  constituted  self-dealing,  willful  misconduct or
recklessness.


                                       19



         (d)  Notwithstanding  the date of adoption  of this  Section  7.2,  the
provisions  of  Section  7.2 shall  apply to any  action  filed or  breaches  of
performance  of duty or any failure of performance of duty by any director on or
after January 27, 1987.

         (e) No  amendment  to or repeal  of this  Section  7.2 or the  relevant
provisions  of the DLA  shall  reduce  the  limitation  on  directors'  personal
liability for or with respect to any events,  acts or omissions of such director
occurring prior to such amendment or repeal, including,  without limitation, the
limitation on personal liability with respect to any Proceedings commenced after
such repeal or modification  based in whole or in part upon any such event,  act
or omission.
