         ------------
corporation shall, to the fullest extent permitted under the laws of the
Commonwealth of Pennsylvania as now or hereafter in effect, indemnify any person
(and his heirs, executors and administrators) who was or is a party, witness or
other participant, or is threatened to be made a party, witness or other
participant, to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative (including, without
limitation, actions by or in the right of the corporation), by reason of the
fact that he is or was a director or officer of the corporation, or is or was
serving at the request of the corporation as a director or officer of another
corporation, partnership, joint venture, trust or other enterprise, against all
expenses (including attorneys' fees, court costs, transcript costs, fees of
experts and witnesses, travel expenses and all other similar expenses),
judgments, fines, penalties and amounts paid in settlement actually and
reasonably incurred by him in connection with such action, suit or proceeding.

     2.  Standard of Conduct.  Except as provided in paragraph 4 below,
         -------------------
indemnification shall be provided under paragraph 1 above only if it is
determined in accordance with the procedure set forth in paragraph 3 below that:
(i) the person seeking indemnification acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation; and (ii) the act or failure to act giving rise to the claim for
indemnification does not constitute willful misconduct or recklessness.
Notwithstanding the foregoing, no person shall be indemnified in any case were
the act or failure to act giving rise to the claim for indemnification is
determined by a court to have constituted willful misconduct or recklessness;
nor shall any person be indemnified in any case where indemnification under this
Article is impermissible by reason of federal law.

     3.  Procedure.  Except as provided under paragraph 4 below, indemnification
         ---------
under paragraph 1 above (unless ordered by a court) shall be made by the
corporation only as authorized in the specific case upon a determination that
indemnification is proper in the circumstances because the person seeking
indemnification has met the applicable standard of conduct set forth in
paragraph 2 above.  All such determinations shall be made in accordance with the
following procedure:

          A.  Method of Determination.  All determinations shall be made:  (i)
              -----------------------
by the board of Directors by majority vote of a quorum consisting or directors
who were not parties to the action, suit or proceeding in respect of which
indemnification is sought; or (ii) in the event that such a quorum is not
obtainable, or, even if obtainable, a majority of such quorum so directs,

                                       5


by Independent Counsel in a written opinion to the Board of directors, a copy of
which shall be delivered to the person seeking indemnification; or (iii) by the
shareholders.

     B.  Selection and Payment of Independent Counsel.  In the event that a
         --------------------------------------------
determination is to be made by Independent Counsel, such Independent counsel
shall be selected by the board of Directors and the law firm or person so
selected shall be subject to the approval of the person seeking indemnification,
which approval shall not be unreasonably with held.  The corporation shall pay
all reasonable fees and expenses of the Independent Counsel.  For purposes of
this Article, "Independent counsel" shall mean a law firm, or a member of a law
firm, that is experienced in matters of corporation law and that has not in the
immediately preceding five years been retained to represent the corporation, the
person, seeking indemnification or any other party to the action, suit or
proceeding giving rise to the claim for indemnification.

          C.  No Presumption.  The termination of any action, suit or proceeding
              --------------
referred to in paragraph 1 above or of any claim, issue or matter therein, by
judgment, order settlement, conviction, or upon a plea of nolo contender, or its
equivalent, shall not of itself create a presumption that a person did not act
in good faith and in a manner which he reasonably believed to be in or not
opposed to the best interests of the corporation or that the act or failure to
act giving rise to the claim for indemnification constitutes willful misconduct
or negligence.

     4.  Successful Defense.  Notwithstanding any other provision of this
         ------------------
Article, to the extent that a person has been successful on the merits or
otherwise in defense of any action, suit or proceeding referred to in paragraph
1 above, or in defense of any claim, issue or matter therein, he shall be
indemnified by the corporation against all expenses (including attorneys' fees,
court costs, transcript costs, fees of experts and witnesses, travel expenses
and all other similar expenses) actually and reasonably incurred by him in
connection therewith.

     5.  Advance Payment of Expenses.  Subject to such terms, conditions and
         ---------------------------
limitations, if any, as the Board of Directors may in its discretion determine
to be appropriate, the corporation shall advance all reasonable expenses
(including attorneys' fees, court costs, transcript costs, fees of experts and
witnesses, travel expenses and all other similar expenses) reasonably incurred
in connection with the defense of or other response to any action, suit or
proceeding referred to in paragraph 1 above upon receipt of any undertaking by
or on behalf of the person seeking the advance to repay all amounts advanced if
it shall ultimately be determined upon final disposition of such action, suit or
proceeding that he is not entitled to be indemnified by the corporation under
the provision of this Article.  Notwithstanding the provisions of the preceding
sentence, the corporation shall not be required to make any advance payment of
expenses (or to make any further advance if one or more advances shall have been
previously made) in the event that a determination is made by the Board of
Directors that the making of an advance or further advance would be
inappropriate in the circumstances.

     6.  No Duplication of Payments.  The corporation shall not be liable under
         --------------------------
this Article to make any payment of amounts otherwise indemnifiable hereunder if
and to the extent that the person seeking indemnification has otherwise actually
received payment under any insurance policy, contract, agreement or otherwise.
In the event that the corporation makes an

                                       6


advance payment of expenses to or on behalf of any person, such person
shall repay to the corporation the amount so advanced, if and to the extent that
he subsequently receives payment therefor under any insurance policy, contract,
agreement, or otherwise.

     7.  Insurance.  The corporation may purchase and maintain at its own
         ---------
expense one or more policies of insurance to protect itself and to protect any
director, officer, employee or agent of the corporation or of another
corporation, partnership, joint venture, trust or other enterprise against any
expense, liability or loss incurred by such person in such capacity, whether or
not the corporation would have the authority to indemnify such person against
any such expense, liability or loss under this Article or under the laws of the
Commonwealth of Pennsylvania.

     8.  Indemnification Agreements.  The corporation shall have authority by
         --------------------------
vote of a majority of the Board of Directors to enter into an Indemnification
Agreement with any person who may be indemnified by the Corporation pursuant to
the provisions of this Article or otherwise.  Any such Indemnification Agreement
may contain such terms and conditions as a majority of the Board of Directors
shall in the exercise of their discretion determine to be necessary or
appropriate, provided that such terms and conditions may not be inconsistent
with the substantive provision of this Article.  The tact that the corporation
has not entered into an Indemnification Agreement with any person shall not in
any way limit the indemnification rights of such person under this Article or
otherwise.

     9.  Non-exclusivity.  The right to indemnification and the payment of
         ---------------
expenses incurred in defending against or otherwise responding to any action,
suit or proceeding in advance of its final disposition as set forth in this
Article shall not he exclusive of any other rights which any person may now have
or hereafter acquire under any agreement, vote of shareholders, vote of
disinterested directors, or under any applicable law or under the Articles of
Incorporation of the corporation, or otherwise.

     10.  Survival of Rights.  The indemnification rights provided to a person
          ------------------
under the provision of this Article shall continue after such person ceases to
be a director or officer of the corporation or of another entity, as to any
action taken, any failure to take action, or any events which occurred while
such person was a director or officer of the corporation or of another entity.

     11.  Modification or Repeal.  The provisions of this Article may be
          ----------------------
modified or repealed in accordance with the procedures for amending these
Bylaws; provided, however, that any such modification or repeal shall not have
any effect upon the indemnification rights of any person as they relate to any
action taken, any failure to take action, or events which occurred prior to the
effective date of such modification or repeal.

                        ARTICLE VII - CORPORATE RECORDS

     1.  Place and Manner of Keeping.  There shall be kept at the registered
         ---------------------------
office or principal place of business of the corporation an original or
duplicate record of the proceedings of the Shareholders and of the Directors,
and the original or a copy of its Bylaws, including all amendments or
alterations thereto to date, certified by the Secretary of the Corporation.  An

                                       7

or principal place of business or at the office of a transfer agent or

therefrom.

     These Bylaws may be amended or repealed either by the vote of Shareholders
entitled to cast at least a majority of the votes which all Shareholders are
entitled to cast thereon, at any regular or special meeting of the Shareholders,
duly convened after notice to the Shareholders of that purpose.  Such proposed
amendment, repeal or new Bylaws, or a summary thereof, shall be set forth in any
notice of such meeting, whether annual, regular or special.

     These Bylaws were adopted by the Shareholders on March 17, 1994.
