which indicates that all securities  offered have been sold or which reregisters
all securities  then remaining  unsold,  shall be deemed to be  incorporated  by
reference in this registration statement and to be part thereof from the date of
filing of such documents.

Item 4.  Description of Securities.

         Not Applicable

Item 5.  Interests of Named Experts and Counsel.

         None

Item 6. Indemnification of Directors and Officers.

         Section  6.01 of the  Company's  By-Laws  provides,  in part,  that the
Company shall, to the fullest extent  permitted by Pennsylvania  law,  indemnify
its  officers  and  directors  in  connection  with any  actual,  threatened  or
completed action, suit or proceeding arising out of their service to the Company
or to another entity at the request of the Company.

         The Company's  directors and officers currently are covered as insureds
under directors' and officers' liability insurance.  Such insurance,  subject to
an annual  renewal and certain  rights of the insurer to terminate,  provides an
aggregate  maximum of  $1,000,000  of coverage for directors and officers of the
Company and its subsidiaries for claims made during the policy period.

         Each Plan provides  that,  except to the extent  insured and except for
willful  misconduct,  the Company  shall  indemnify  any employee of the Company
against  any  liability  incurred  by  reason  of the  employee's  service  as a
fiduciary with respect to the Plan.

Item 9. Undertakings.

         The undersigned registrant 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 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.  The  registrant
further  undertakes  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.  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 indemnification provisions
described in Item 6, 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.

statement  to be  signed  on its  behalf  by  the  undersigned,  thereunto  duly
