taken, or any failure to act, prior to such amendment, repeal or
adoption.  This Section 17 may be amended or repealed only with

                            ARTICLE V
                         INDEMNIFICATION

     Section 1.     Indemnification Granted.  Every person who is
or was a director, officer or employee of the Company or of any
other corporation, partnership, joint venture, trust or other
enterprise which such person serves or served as such at the
request of the Company (hereinafter referred to as an "eligible
person") shall in accordance with this Article V, but not if
prohibited by law, be indemnified by the Company as hereinafter
provided against reasonable expense and any liability paid or
incurred by such person in connection with or resulting from any
claim in which such person may be involved, as a party or
otherwise, by reason of such person's being or having been a
director, officer or employee of the Company or such other
enterprise, whether or not such person continues to be such at
the time such liability or expense shall have been paid or
incurred.

     Section 2.     Certain Definitions.  As used in this Article
V, the term "claim" shall mean any threatened or actual claim,
action, suit or proceeding (whether brought by or in the right of
the Company or such other enterprise or otherwise), whether
civil, criminal, administrative or investigative; the term
"expense" shall mean counsel fees and disbursements and all other
expenses (except any liability) incurred in connection with any
claim; and the term "liability" shall mean amounts of judgments,
fines or penalties against, and amounts paid in settlement by, an
eligible person with respect to any claim.

     Section 3.     Expense Reimbursement to the Extent
Successful.  Any eligible person who has been wholly successful,
on the merits or otherwise, with respect to any claim shall be
reimbursed by the Company for such person's reasonable expense.
Any eligible person who has been partially successful shall be
proportionately reimbursed by the Company for such person's
reasonable expense.

     Section 4.     Indemnification Where Not Wholly Successful.
Any eligible person who has been partially unsuccessful and any
other eligible person not described in Section 3 of this Article
V shall be reimbursed by the Company for such person's reasonable
expense and for any liability if a Referee shall deliver to the
Company the written finding of such Referee that such person
acted in good faith and in a manner such person reasonably
believed to be in, or not opposed to, the best interests of the
Company, and in addition with respect to any criminal action or
proceeding, had no reasonable cause to believe the conduct of
such person was unlawful.  Where such person is found by the
Referee to have met the foregoing standards of conduct with
respect to one or more but not all the claims made against such
person, such person shall be entitled to indemnification for 
such expense and liability in such proportion as the Referee 
shall determine.  The termination of any claim by judgment, 
order, settlement (whether with or without court approval), 
adverse decision, or conviction after trail or upon a plea of 
guilty or of nolo contendere or its equivalent, shall not of 
itself create a presumption that an eligible person did not meet
the foregoing standards of conduct.  The person claiming 
indemnification shall, at the request of the Referee, appear 
before the Referee and answer questions which the Referee deems 
relevant and shall be given ample opportunity to present to the 
Referee evidence upon which such person relies for indemnifica-
tion; and the Company shall at the request of the Referee, make
available to the Referee facts, opinions or other evidence in 
any way relevant for the Referee's finding which are within the
possession or control of the Company.  As used in this Article V,
the term "Referee" shall mean independent legal counsel (who may
be regular independent legal counsel of the Company), or other 
disinterested person or persons, selected to act as such 
hereunder by the board of directors of the Company, whether or 
not a disinterested quorum exists.

     Section 5.     Advancement of Expenses.  Any expense
incurred with respect to any claim may be advanced by the Company
prior to the final disposition thereof upon receipt of an
undertaking by or on behalf of the recipient to repay such amount
if it is ultimately determined that such recipient is not to be
indemnified under this Article V.

     Section 6.     Article V Not Exclusive; Survival of Rights.
The rights of indemnification provided in this Article V shall be
in addition to any rights to which any eligible person may
otherwise be entitled by contract or as a matter of law; and in
the event of such person's death, such rights shall extend to the
heirs and legal representatives of such person.

                           ARTICLE VI
                SHARE CERTIFICATES AND TRANSFERS

     Section 1.     Share Certificates.  Share certificates shall
be in such form as the board of directors may from time to time
determine.  Each certificate shall be signed by the chairman of
the board, the president, the treasurer or the secretary of the
Company, by manual or facsimile signature.

     Section 2.     Transfer Agent and Registrar.  The board of
directors may from time to time appoint one or more transfer
agents and may appoint one or more registrars of transfer, each
to act with respect to such preferred and common shares of the
Company as the board of directors may designate.  No share
certificate of the Company shall be valid or binding unless
countersigned, manually or by facsimile signature, by a transfer
agent if one has been appointed to act with respect to the shares
evidenced by such certificate, and registered before issue by a
registrar if one has been appointed to act with respect to the
shares evidenced by such certificate.

     Section 3.     Signatures by Former Corporate Officers or
Agents.  In case any officer of the Company, or any authorized
signatory of any transfer agent or registrar, who has signed, or
whose facsimile signature has been placed upon, any share
certificate shall have ceased to be such officer or authorized
signatory because of death, resignation or otherwise, before the
certificate is issued, it may be issued with the same effect as
if the officer or authorized signatory had not ceased to be such
at the date of its issue.
                                
                           ARTICLE VII
                           AMENDMENTS
                                
     These By-laws may be altered, amended, added to or repealed
by the board of directors at any meeting of the board duly
convened with or without notice of that purpose, subject to the
power of the shareholders to change such action.
                                
                          ARTICLE VIII
                  INDEMNIFICATION FOR DIRECTORS
                                

     Section 1.     Right to Indemnification.  Except as
prohibited by law, every director 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 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 a "claim"); provided, that no
such right of indemnification shall exist with respect to a claim
brought by a director against the Company except as provided in
the last sentence of this Section 1.  Indemnification hereunder
shall include the right to have expenses incurred by such person
in connection with a claim paid in advance by the Company prior
to final disposition of such claim, subject to any obligation
which may be imposed by law, By-law, agreement or otherwise to
reimburse the Company in certain events.  As used herein,
"expenses" shall include fees and expenses of counsel selected by
any such director and "liability" shall include amounts of
judgments, excise taxes, fines, penalties and amounts paid in
settlement.  With respect to any claim brought by a director or
other person against the Company, the director or other person
shall be entitled to be indemnified for expenses incurred in
connection with such claim pursuant to this Section 1 only (i) if
the claim is a suit brought as a claim for indemnity under
Section 2 of this Article VIII or otherwise, (ii) if the director
or other person is successful in whole or in part in the claim
for which expenses are claimed or (iii) if the indemnification
for expenses is included in a settlement of the claim or is
awarded by a court.

     Section 2.     Right of Claimant to Bring Suit.  If a claim
under Section 1 of this Article VIII is not paid in full by the
Company within thirty days after a written claim has been
received by the Company, the claimant may at any time thereafter
bring suit against the Company to recover the unpaid amount of
the claim and, if successful in whole or in part, the claimant
shall also be entitled to be paid the expense of prosecuting such
claim.  It shall be a defense to any such suit to recover
indemnification that the claimant's conduct was such that under
Pennsylvania law the Company is prohibited from indemnifying the
claimant 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, legal counsel and its
shareholders) to have made a determination prior to the
commencement of such suit that indemnification of the claimant is
proper in the circumstances, nor an actual determination by the
Company (including its board of directors, legal counsel or its
shareholders) that the claimant's conduct was such that
indemnification is prohibited by law, shall be a defense to the
suit to recover indemnification or create a presumption that the
claimant's conduct was such that indemnification is prohibited by
law.  The only defense to any such suit to receive payment of
expenses in advance shall be failure to make an undertaking to
reimburse if such an undertaking is required by law, By-law,
agreement or otherwise.

     Section 3.     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 claim, 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 Article.  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 as provided herein.

     Section 4.     Non-Exclusivity; Nature and Extent of Rights.
The right of indemnification provided for in this Article VIII(i)
shall not be deemed exclusive of any other rights, whether now
existing or hereafter created, to which those seeking
indemnification hereunder may be entitled under any provision of
the Articles or By-laws, or any agreement, vote of shareholders
or directors or otherwise, (ii) shall be deemed to create
contractual rights in favor of persons entitled to
indemnification hereunder, (iii) shall continue as to persons who
have ceased to have the status pursuant to which they were
entitled or were denominated as entitled to indemnification
hereunder and shall inure to the benefit of the heirs and legal
representatives of persons entitled to indemnification hereunder
and (iv) shall be applicable to claims commenced after the
adoption hereof, whether arising from acts or omissions occurring
before or after the adoption hereof.  The right of
indemnification provided for herein may not be amended or
repealed so as to limit in any way the indemnification provided
for herein with respect to any acts or omissions occurring prior
to any such amendment or repeal.
