       INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3.  INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE
         ----------------------------------------------

    The  following  documents  filed  by  the  Company  with  the
Securities and Exchange Commission are incorporated herein by
reference:

   a.   Annual Report on Form 10-K for the fiscal year ended
        December 31, 1999 filed by the Company pursuant to Section 13(a)
        of the Securities Exchange Act of 1934 ("Exchange Act").

        April 15, 1986 (File No. 33-4885) under the Securities Act of
        1933, including all amendments and reports subsequently filed for
        the purpose of updating such description.

All documents subsequently filed by the Company pursuant to Sections

post-effective amendment which indicates that all securities offered hereby
have been sold or which deregisters all securities then remaining unsold,

Item 4. DESCRIPTION OF SECURITIES
        --------------------------

   Not applicable.

Item 5. INTERESTS OF EXPERTS AND NAMED COUNSEL
        --------------------------------------

   Not applicable.

Item 6.  INDEMNIFICATION OF OFFICERS AND DIRECTORS
        -----------------------------------------

   The Company's Certificate of Incorporation and By-Laws contain provisions
permitted by the Delaware General Corporation Law

 Page II-2

("DGCL") (under which the Company is organized) that provide that directors and
officers will be indemnified by the Company to  the fullest  extent  permitted
by law for all losses that may be incurred by them in connection with any
action, suit or proceeding in which they may become involved by reason of
their service as a director or officer of the Company. Under Section 145 of
the DGCL, a corporation has the power to indemnify directors and officers
under certain prescribed circumstances and subject to certain limitations
against certain costs and expenses, including attorney's fees actually and
reasonably incurred in connection with any action, suit or proceeding,
whether civil, criminal, administrative or investigative, to which any of
them is a party by reason of being a  director or officer of the corporation
if it is determined that the director or officer acted in accordance with the
applicable standard  of conduct set forth in such statutory provision.

    In  addition,  the  Company's  Certificate  of  Incorporation contains
provisions permitted by the DGCL that limit the monetary liability of
directors of the Company for certain breaches of their fiduciary duty, and
its By-Laws provide for the advancement by  the Company to directors and
officers of expenses incurred by them  in connection with a proceeding of a
type to which the duty of indemnification applies.  The Company maintains
directors' and officers' liability insurance to insure its directors and
officers against certain liabilities incurred in their capacity as  such,
including claims based on breaches of duty, negligence,error and other
wrongful acts.

   Reference is made to the Exhibit Index on Page II-6.

Item 9.   UNDERTAKINGS
            ------------

   The undersigned registrant hereby undertakes:

(1)    To file, during the 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 this registration statement (or
                  the most recent post-effective amendment hereof) which,
                  individually or in the aggregate, represent a fundamental
                  change in the information set forth in this registration
                  statement.

 Page II-3

        (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 (1)(i) and (1)(ii)
                  --------  -------
                  shall apply to this registration statement on Form S-8 if
                  the information required to be included in the post-
                  effective amendment by these 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 this 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.

         (4)   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.
                  ---- ----

         (5)   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

 Page II-4


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 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 Township of Lower Salford, Commonwealth of
Pennsylvania, on this 17th day of May, 2000.
