Item 4.  Description of Securities.
         -------------------------

          Not Applicable.


Item 5.  Interests of Named Experts and Counsel.
         --------------------------------------

          Not Applicable.


Item 6.  Indemnification of Directors and Officers.
         -----------------------------------------

          The Pennsylvania  Business  Corporation Law generally  provides that a
company  shall have the power to indemnify  its  officers,  directors and others
against liability  incurred by them by reason of their position with the company
if such person acted in good faith and in a manner reasonably believed to be in,
or not opposed to, the best  interest of the company,  and,  with respect to any
criminal action or proceeding  related to a third-party  action, the indemnified
party had no reasonable cause to believe his conduct was unlawful.

          Section  1 of  Article  VII  of  the  Company's  Bylaws  provides  for
mandatory  indemnification of directors and officers against third-party actions
in such circumstances. Section 2 of Article VII of the Company's Bylaws provides
for  mandatory

                                      II-2


indemnification for any director or officer made party to any derivative suit if
he acted in good  faith  and in a manner  reasonably  believed  to be in, or not
opposed  to,  the  best  interest  of  the  Company;   provided,   however,   no
indemnification  against  expenses will be made where the person shall have been
adjudged to be liable for  negligence or misconduct  in the  performance  of his
duty to the Company unless and to the extent that the applicable Court of Common
Pleas  shall  determine  such  person  is  fairly  and  reasonably  entitled  to
indemnity.  Under  Section 3 of Article  VII, an  independent  determination  of
disinterested  directors,  legal  counsel or  shareholders  of the Company  will
determine whether the person is entitled to indemnification under Sections 1 and
2,  unless  indemnification  is ordered by a court.  In  addition,  Section 5 of
Article VII of the Bylaws provides for advancement of expenses in advance of the
final  disposition  of  any  action,  suit  or  proceeding  upon  receipt  of an
undertaking,   by  or  on  behalf  of  the  person  who  may  be   entitled   to
indemnification  under  Sections 1, 2 and 4 of Article VII, to repay such amount
if it shall  ultimately be determined  that he is not entitled to be indemnified
by the Company.

          The Pennsylvania  Business  Corporation Law also permits a corporation
to include in its bylaws,  and in  agreements  between the  corporation  and its
directors and officers, provisions expanding the scope of indemnification beyond
that  specifically  provided  by  the  Pennsylvania  Business  Corporation  Law;
provided, however,  indemnification shall not be permitted in any case where the
act giving rise to the claim for  indemnification  is  determined  by a court to
have constituted willful misconduct or recklessness. Section 4 of Article VII of
the  Company's  Bylaws  generally  provides  for  mandatory  indemnification  of
officers  and   directors   acting  on  behalf  of  the  Company,   except  that
indemnification  shall not be permitted in any case where the act giving rise to
the claim  for  indemnification  is  determined  by a court to have  constituted
willful  misconduct  or  recklessness.  Indemnification  under Section 4 will be
provided  without  the  independent  determination  or court  order  required by
Section  3  as   described   above.   The  Company  also  has  entered  into  an
Indemnification  Agreement with each of the executive  officers and directors of
the  Company.   The  Indemnification   Agreements  provide  the  same  scope  of
indemnification as provided under the Bylaws. The Indemnification Agreements are
direct  contractual  obligations  of the Company in favor of the  directors  and
officers.  Therefore,  in the event that the Bylaws are subsequently  changed to
reduce the scope of  indemnification,  executive  officers  and  directors  with
Indemnification Agreements will not be affected by such changes.

          In addition,  the Company maintains  directors and officers  insurance
under which its directors and officers are insured against  certain  liabilities
that may be incurred by them in their capacities as such.


Item 7.  Exemption from Registration Claimed.

                herein)


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:

                                      II-3


               (i) To include any prospectus required by section 10(a)(3) of the
Securities Act of 1933, as amended ("1933 Act");

               (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.  Notwithstanding the foregoing, any increase or decrease in 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 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) of
this section do not apply if the registration statement is on Form S-3, Form S-8
or Form F-3,  and 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 1934 Act that are  incorporated  by reference  in the  registration
statement.

          (2) That, for the purpose of determining  any liability under the 1933
Act, 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 1933 Act, each filing of the  registrant's
annual  report  pursuant to section 13(a) or section 15(d) of the 1934 Act (and,
where  applicable,  each  filing of an employee  benefit  plan's  annual  report
pursuant to section 15(d) of the 1934 Act) 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 1933 Act
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 Commission such  indemnification  is
against  public  policy  as  expressed  in  the  1933  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  1933  Act  and  will  be  governed  by the  final
adjudication of such issue.

                                      II-4
