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 of Chapter 17 of the Pennsylvania Business Corporation Law of
1988, as amended (the "PBCL"), contains provisions relating to the
indemnification of persons by a Pennsylvania business corporation, including
directors and officers of the corporation.

     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 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 Subchapter D
of Chapter 17 of the PBCL. The Registrant currently maintains directors and
officers liability insurance on behalf of its directors and officers.

                                       3



     Section 7.1 of the Registrant's Bylaws contains provisions requiring the
Registrant to indemnify and hold harmless directors and officers to the fullest
extent and manner authorized or permitted by the laws of the Commonwealth of
Pennsylvania.

     24.   Power of Attorney (included as part of the signature page hereto)

Item 9. Undertakings.

     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)(l)(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 15(d) of the Securities
Exchange Act of 1934 that are incorporated by reference in the registration
statement.

                                       4



     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.

     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 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.

     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.

                                       5



                        SIGNATURES AND POWER OF ATTORNEY

     Pursuant to the requirements of the Securities Act of 1933, the Registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-8 and has duly caused this registration
statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Conshohocken, Commonwealth of Pennsylvania on this
31st day of March, 2003.
