supersedes such statement.  Any statement so modified or superseded shall not be
deemed,  except as so  modified  or  superseded,  to  constitute  a part of this
Registration Statement.

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  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.

                                      II-2


          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.
