Item 6.  Indemnification of Directors and Officers.

         Chapter 17, Subchapter D of the Pennsylvania Business Corporation Law
of 1988, as amended (the "PBCL") contains provisions permitting indemnification
of officers and directors of a business corporation in Pennsylvania.

         Sections 1741 and 1742 of the PBCL provide that a business corporation
may indemnify directors and officers against liabilities and expenses they may
incur as such in connection with any threatened, pending or completed civil,
administrative or investigative proceeding, provided that the particular person
acted in good faith and in a manner he or she reasonably believed to be in, or
not opposed to, the best interests of the corporation, and, with respect to any
criminal proceeding, had no reasonable cause to believe his or her conduct was
unlawful. In general, the power to indemnify under these sections does not exist
in the case of actions against a director or officer by or in the right of the
corporation if the person otherwise entitled to indemnification shall have been
adjudged to be liable to the corporation unless it is judicially determined
that, despite the adjudication of liability but in view of all the circumstances
of the case, the person is fairly and reasonably entitled to indemnification for
specified expenses.

         Section 1743 of the PBCL provides that the corporation is required to
indemnify directors and officers against expenses they may incur in defending
actions against them in such capacities if they are successful on the merits or
otherwise in the defense of such actions.

         Section 1746 of the PBCL grants a corporation broad authority to
indemnify its directors and officers for liabilities and expenses incurred in
such capacity, except in circumstances where 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.

         Section 1747 of the PBCL permits a corporation to purchase and maintain
insurance on behalf of any person who is or was a director or officer of the
corporation, or is or was serving at the request of the corporation as a
representative of another corporation or other enterprise, against any liability
asserted against such person and incurred by him or her in any such capacity, or
arising out of his or her status as such, whether or not the corporation would
have the power to indemnify the person against such liability under Chapter
17-Subchapter D of the PBCL.

         The Registrant's Bylaws provide a right to indemnification to the full
extent permitted by law, for expenses (including attorneys' fees), damages,
punitive damages, judgments, penalties, fines and amounts paid in settlement,
actually and reasonably incurred by any director or officer whether or not the
indemnified liability arises or arose from any threatened, pending or completed
proceeding by or in the right of the Registrant (a derivative action) by reason
of the fact that such director or officer is or was serving as a director,
officer, employee or agent of the Registrant or, at the request of the
Registrant, as a director, officer, partner, fiduciary or trustee of another
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise, unless the act or failure to act giving rise to the claim for
indemnification is financially determined by a court to have constituted willful
misconduct or recklessness. The Bylaws provide for the advancement of expenses
to an indemnified party upon receipt of an undertaking by the party to repay
those amounts if it is finally determined that the indemnified party is not
entitled to indemnification.

         The Registrant's Bylaws authorize the Registrant to take steps to
ensure that all persons entitled to indemnification are properly indemnified,
including, if the Board of Directors so determines, purchasing and maintaining
insurance. The Registrant maintains directors and officers insurance.

Item 7.  Exemption from Registration Claimed.

         Not applicable.

                           and incorporated herein by reference).
           5.1             Opinion of Morgan Lewis & Bockius, LLP.
          23.1             Consent of Morgan Lewis & Bockius LLP (contained in
                           the opinion of counsel filed as Exhibit 5.1).
          23.2             Consent of KPMG LLP.
                           Consent of Arthur Andersen LLP (omitted pursuant to

                           page hereof).

Item 9.  Undertakings.

     (a) The undersigned registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement:

                  (i) To include any prospectus required by Section 10(a)(3) of
         the Securities Act;

                  (ii) To reflect in the prospectus any facts or events arising
         after the effective date of the registration statement (or the most
         recent post-effective amendment thereof) which, individually or in the
         aggregate, represent a fundamental change in the information set forth
         in the registration statement; and

                  (iii) To include any material information with respect to the
         plan of distribution not previously disclosed in the registration
         statement or any material change to such information in the
         registration statement;

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the registrant pursuant to
Section 13 or Section 15(d) of the Exchange Act that are incorporated by
reference in this Registration Statement.

         (2) That, for the purpose of determining any liability under the
Securities Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (3) To remove from registration by means of a post-effective amendment
any of the securities being registered that remain unsold at the termination of
the offering.

     (b) The undersigned registrant hereby undertakes that, for the purpose of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act that is incorporated by reference in this registration statement
shall be deemed to be a new registration statement relating to the securities
offered therein and the offering of such securities at that time shall be deemed
to be the initial bona fide offering thereof.

     (c) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Act and is, therefore, unenforceable.
In the event that a claim for indemnification against such liabilities (other
than the payment by the registrant of expenses incurred or paid by a director,
officer or controlling person of the registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.
