prospectively only and shall not affect any action taken, or any failure to act,
prior to such amendment, repeal or adoption. This Section 17 may be amended or

                                    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.

                                      -7-



     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 sh all 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 indemnification; 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.

                                      -8-



     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.

                                      -9-



                                  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

                                      -10-



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.

                          ____________________________
