Item 9.   UNDERTAKINGS

               The Company 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, as amended;

                               (ii) To reflect in the prospectus
          any facts or events arising after the effective date of
          this 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 this Registration Statement.
          Notwithstanding the foregoing, any increase or decrease
          in the volume of securities offered (if the total
          dollar value of securities offered would not exceed
          that which was registered) and any deviation from the
          low or high end of the estimated maximum offering range
          may be reflected in the form of prospectus filed with
          the Commission pursuant to Rule 424(b) if, in the
          aggregate, the changes in volume and price represent no
          more than a 20% change in the maximum aggregate
          offering price set forth in the "Calculation of
          Registration Fee" table in the effective Registration
          Statement.

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

                           Provided, however, that paragraphs
          (1)(i) and (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
          Company pursuant to Section 13 or Section 15(d) of the
          Securities Exchange Act of 1934, as amended, that are
          incorporated by reference in this Registration
          Statement.

                (2) That, for the purpose of determining any
     liability under the Securities Act of 1933, as amended, 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 any registration by means of a
     post-effective amendment any of the securities being
     registered which remain unsold at the termination of the
     offering.

           The  Company hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, as
amended, each filing of the Company's annual report pursuant to
Section 13(a) or Section 15(d) of the Securities Exchange Act of
1934, as amended, 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.

           Insofar as indemnification for liabilities arising
under the Securities Act of 1933, as amended, may be permitted to
directors, officers and controlling persons of the Company
pursuant to the foregoing provisions, or otherwise, the Company
has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy
as expressed in the Securities Act of 1933, as amended, and is,
therefore, unenforceable.  In the event that a claim  for
indemnification against such liabilities (other than the payment
by the Company of expenses incurred or paid by a director,
officer or controlling person of the Company 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 Company 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 Securities Act of 1933, as amended,
and will be governed by the final adjudication of such issue.
                           
                           
                           SIGNATURES
                           
           Pursuant to the requirements of the Securities Act of
1933, as amended, 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 Town of West Chester,
Commonwealth of Pennsylvania, on the date below:

Item 9.   UNDERTAKINGS

               The Company 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, as amended;

                               (ii) To reflect in the prospectus
          any facts or events arising after the effective date of
          this 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 this Registration Statement.
          Notwithstanding the foregoing, any increase or decrease
          in the volume of securities offered (if the total
          dollar value of securities offered would not exceed
          that which was registered) and any deviation from the
          low or high end of the estimated maximum offering range
          may be reflected in the form of prospectus filed with
          the Commission pursuant to Rule 424(b) if, in the
          aggregate, the changes in volume and price represent no
          more than a 20% change in the maximum aggregate
          offering price set forth in the "Calculation of
          Registration Fee" table in the effective Registration
          Statement.

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

                           Provided, however, that paragraphs
          (1)(i) and (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
          Company pursuant to Section 13 or Section 15(d) of the
          Securities Exchange Act of 1934, as amended, that are
          incorporated by reference in this Registration
          Statement.

                (2) That, for the purpose of determining any
     liability under the Securities Act of 1933, as amended, 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 any registration by means of a
     post-effective amendment any of the securities being
     registered which remain unsold at the termination of the
     offering.

           The  Company hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, as
amended, each filing of the Company's annual report pursuant to
Section 13(a) or Section 15(d) of the Securities Exchange Act of
1934, as amended, 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.

           Insofar as indemnification for liabilities arising
under the Securities Act of 1933, as amended, may be permitted to
directors, officers and controlling persons of the Company
pursuant to the foregoing provisions, or otherwise, the Company
has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy
as expressed in the Securities Act of 1933, as amended, and is,
therefore, unenforceable.  In the event that a claim  for
indemnification against such liabilities (other than the payment
by the Company of expenses incurred or paid by a director,
officer or controlling person of the Company 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 Company 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 Securities Act of 1933, as amended,
and will be governed by the final adjudication of such issue.
                           
                           
                           SIGNATURES
                           
           Pursuant to the requirements of the Securities Act of
1933, as amended, 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 Town of West Chester,
Commonwealth of Pennsylvania, on the date below:
