Item 4.  Description of Securities.

     Not Applicable.

Item 5.  Interests of Named Experts and Counsel.

     Not Applicable.


Item 6.  Indemnification of Directors and Officers.

     Subchapter D (Sections 1741 through 1750) of Chapter 17 of the Pennsylvania
Business Corporation Law of 1988 (the "PBCL") contains provisions for mandatory
and discretionary indemnification of a corporation's directors, officers,
employees and agents (collectively "Representatives") and related matters.

     Under Section 1741, subject to certain limitations, a corporation has the
power to indemnify directors, officers and other Representatives under certain
prescribed circumstances against expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
in connection with a threatened, pending or completed action or proceeding,
whether civil, criminal, administrative or investigative, to which any of them
is a party or threatened to be made a party by reason of his being a
Representative of the corporation or serving at the request of the corporation
as a Representative of another corporation, partnership, joint venture, trust or
other enterprise, if he 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,
with respect to any criminal proceeding, had no reasonable cause to believe his
conduct was unlawful.

     Section 1742 provides for indemnification with respect to derivative and
corporate actions similar to that provided by Section 1741. However,
indemnification is not provided under Section 1742 in respect of any claim,
issue or matter as to which a Representative has been adjudged to be liable to
the corporation unless and only to the extent that the proper court determines
upon application that, despite the adjudication of liability but in view of all
the circumstances of the case, a Representative is fairly and reasonably
entitled to indemnity for the expenses that the court deems proper.

     Section 1743 provides that indemnification against expenses is mandatory to
the extent that a Representative has been successful on the merits or otherwise
in defense of any such action or proceeding referred to in Section 1741 or 1742.

     Section 1744 provides that unless ordered by a court, any indemnification
under Section 1741 or 1742 shall be made by the corporation as authorized in the
specific case upon a determination that indemnification of a Representative is
proper because the Representative met the applicable standard of conduct, and
such determination will be made by the board of directors by a majority vote of
a quorum of directors not parties to the action or proceeding; if a quorum is
not obtainable or if obtainable and a majority of disinterested directors so
directs, by independent legal counsel; or by the shareholders.

     Section 1745 provides that expenses incurred by a Representative in
defending any action or proceeding referred to in Subchapter D of Chapter 17 of
the PBCL may be paid by the corporation in advance of the final disposition of
such action or proceeding upon receipt of an undertaking by or on behalf of the
Representative to repay such amount if it shall ultimately be determined that he
is not entitled to be indemnified by the corporation.

     Section 1746 provides generally that except in any case 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, the
indemnification and advancement of expenses provided by


Subchapter D of Chapter 17 of the PBCL shall not be deemed exclusive of any
other rights to which a Representative seeking indemnification or advancement of
expenses may be entitled under any bylaw, agreement, vote of shareholders or
disinterested directors or otherwise, both as to action in his official capacity
and as to action in another capacity while holding that office.

     Section 1747 grants a corporation the power to purchase and maintain
insurance on behalf of any Representative against any liability incurred by him
in his capacity as a Representative, whether or not the corporation would have
the power to indemnify him against that liability under Subchapter D of Chapter
17 of the PBCL.

     Sections 1748 and 1749 apply the indemnification and advancement of
expenses provisions contained in Subchapter D of Chapter 17 of the PBCL to
successor corporations resulting from consolidation, merger or division and to
service as a Representative of a corporation or an employee benefit plan.

     Article VII of the Registrant's bylaws provides indemnification to
directors and officers for all actions taken by them and for all failures to
take action to the fullest extent permitted by Pennsylvania law against all
expense, liability and loss reasonably incurred or suffered by them in
connection with any threatened, pending or completed action, suit or proceeding
(including, without limitation, an action, suit or proceeding by or in the right
of the Registrant), whether civil, criminal, administrative, investigative or
through arbitration. Article VII also permits the Registrant, by action of its
board of directors, to indemnify officers, employees and other persons to the
same extent as directors. Amendments, repeals or modifications of Article VII
can only be prospective, and such changes require the affirmative vote of not
less than all of the directors then serving or the holders of a majority of the
outstanding shares of stock entitled to vote in elections of directors. Article
VII further permits the Registrant to maintain insurance, at its expense, for
the benefit of any person on behalf of whom insurance is permitted to be
purchased by Pennsylvania law against any such expenses, liability or loss,
whether or not the Regsistrant would have the power to indemnify such person
against such expense, liability or loss under Pennsylvania or other law.

Item 7.  Exemption from Registration Claimed.

     Not Applicable.

Item 8.  Exhibits.

     The following exhibits are filed as part of this Registration Statement.

          filed on May 9, 2000)

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 of 1933;

               (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;

               (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 with or furnished to the
Commission by the Registrant pursuant to Section 13 or Section 15(d) of the
Securities Exchange Act of 1934 that are incorporated by reference in the
Registration Statement.

          (2)  That, for the purpose of determining any liability under the
Securities Act of 1933, 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 which remain unsold at the
termination of the offering.

     (b)  The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
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 of 1933 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 Securities and Exchange 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.


                                  SIGNATURES

     Pursuant to the requirements of the Securities Act of 1933, the Registrant

requirements for filing on Form S-8 and has duly caused this Registration

authorized, in Malvern, Pennsylvania on September 19, 2001.
