preceding fiscal year shall be presented at the Annual Meeting, and shall be

purpose of the meeting need be specified in the Waiver of Notice of such
Meeting.

       Attendance of a person, either in person or by proxy, at any meeting

       Section 2.11 Adjournment of Meetings:

       Adjournment of any meeting may be taken, but any meeting at which
Directors are to be elected shall be adjourned only from day to day, or for such
longer periods not exceeding fifteen days each, as may be directed by the
holders of at least a majority of the shares entitled to be voted at an election
of directors, until such Directors have been elected. When a meeting is
adjourned, it shall not be necessary to give any notice of the adjourned meeting
or of the business to be transacted thereat, other than by announcement at the
meeting at which such adjournment is taken. In case of any meeting called for
the election of Directors, those who attend the second of such adjourned

the purpose of electing 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.

       The directors, other than any who (i) 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, or (ii) shall be nominated by the Board of Directors or
any appropriately empowered committee thereof to serve for a term of one year
(the "One Year Class"), 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 1999 for a term expiring at the Annual Meeting
of Shareholders to be held in 2002 shall be designated as "Class A"; the second
Three Year Classes to be elected at the Annual Meeting of Shareholders in 2000
for a term expiring at the Annual Meeting of Shareholders to be held in 2003
shall be designated as "Class B"; and the third Three Year Class to be elected
at the

                                        4




Annual Meeting of Shareholders held in 1998 for a term expiring at the Annual
Meeting of Shareholders to be held in 2001 shall be designated "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 that Annual Meeting of Shareholders held in the third year following the year
of their election, expect that the successors to the Directors in the One Year
Class shall be elected to hold office for a term expiring at the Annual Meeting
of Shareholders held in the next succeeding year."

       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.

shareholders. The Chairman may appoint another member of the Board to preside in
his absence.


       Section 3.2 Quorum for Directors' Meetings:

       A majority of the Directors in office shall be necessary to constitute a
quorum for the transaction of business, and the acts of a majority of the
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

Committee, as the case may be, and shall be filed with the Secretary of the

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.

       Section 3.4 Vacancies in Board of Directors:

       Except as otherwise provided for or fixed pursuant to the Articles of
Incorporation of the Corporation, newly created directorships resulting from an
increase in the number of Directors, and any vacancies on the Board of Directors
resulting from death, resignation, disqualification, removal or other cause
shall be filled by the vote of a majority of the remaining members of the Board,
even though less than a quorum. Any person so elected shall hold office for the
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
have been elected and qualified. No decrease in the number of Directors
constituting the Board of Directors shall shorten the term of any incumbent
Director.

Board may meet for the purpose of organization or otherwise:

          (a) Immediately following their election, or at such time and place as
     shall be fixed by vote of the shareholders at the Annual Meeting (and in
     either such case no notice of such meeting to the newly elected Directors
     shall be necessary in order legally to constitute the meeting, provided a
     majority of the whole Board shall be present); or

                                        6

          (a) The Corporation shall indemnify and hold 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

                                       13



     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.

          (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's fees and disbursements,
     punitive and other damages, judgements, 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.

          (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's conduct
     constituted willful misconduct or recklessness.

          (d) Expenses incurred by a director or officer in defending a
     Proceeding shall be paid by the Corporation

                                       14



          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.

                                       15


                 

          (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

                                       16



     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.

          (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.
