                  The Common Stock and Rights to purchase Series B Junior
Participating Preferred Stock are registered under the Exchange Act.

Item 5.           Interests of Named Experts and Counsel.

                  The validity of the Common Stock registered hereunder has been
passed upon for the Company by William J. Merritt, Esq., 781 Third Avenue, King

                  Sections 1741-1750 of the Pennsylvania Business Corporation
Law of 1988 (the "BCL") and the Company's By-Laws provide for indemnification of
the Company's directors and officers and certain other persons. Under Sections
1741-1750 of the BCL, directors and officers of the Company may be indemnified
by the Company against all expenses incurred in connection with actions
(including, under certain circumstances, derivative actions) brought against
such director or officer by reason of his or her status as a representative of
the Company, or by reason of the fact that such director or officer serves or
served as a representative of another entity at the Company's request, so long
as the director or officer acted in good faith and in a manner he or she
reasonably believed to be in, or not opposed to, the best interests of the
Company. As permitted under the BCL, the Company's By-Laws provide that the
Company shall indemnify directors and officers against all expenses incurred in

director or officer by reason of the fact that he or she is or was a director or
officer of the Company, or by reason of the fact that such director or officer
serves or served as an employee or agent of any entity at the Company's request,
unless the act or failure to act on the part of the director or officer giving
rise to the claim for indemnification is determined by a court in a final,
binding adjudication to have constituted willful misconduct or recklessness.

Item 7.           Exemption from Registration Claimed.

                  Not applicable.

                          and Protection Plan, as amended through July 31, 2001

         5                Opinion of William J. Merritt, Esquire

         23.1             Consent of Independent Public Accountants

         23.2             Consent of William J. Merritt, Esquire
                          (included in Exhibit 5)

         24               Power of Attorney (see signature pages at pp. 7 - 8)

                  The Registrant hereby undertakes that the Plan and any
amendments thereto have been and will be submitted to the Internal Revenue
Service ("IRS") in a timely manner and all changes required by the IRS in order
to qualify the Plan under Section 401 of the Internal Revenue Code have been or
will be made.

Item 9.           Undertakings.

                  The undersigned Registrant hereby undertakes as follows:

                  (a) To file, during any period in which offers or sales are
being made pursuant to this Registration Statement, a post-effective amendment
to this Registration Statement:

                           (i) To include any prospectus required by Section
10(a)(3) of the Securities Act;

                           (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 aggregate,
represent a fundamental change in the information set forth in this 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 is registered) and any deviation from the low or high end of
the estimated maximum 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 20 percent change in the maximum
aggregate offering price set forth in "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 to such information in this
Registration Statement;

                                      -5-


<PAGE>

provided, however, that paragraphs (i) and (ii) above 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 by the Registrant pursuant to Section 13 or
15(d) of the Exchange Act that are incorporated by reference in this
Registration Statement.

                  (b) That, for the purpose of determining any liability under
the Securities 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.

                  (c) 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.

                  The undersigned Registrant hereby undertakes that, for
purposes of determining any liability under the Securities Act, each filing of
the Registrant's annual report pursuant to Section 13(a) or 15(d) of the
Exchange Act 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 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 Securities 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 Securities Act and will be governed by the final
adjudication of such issue.

such director or officer by reason of his or her status as a representative of
the Company, or by reason of the fact that such director or officer serves or

serves or served as an employee or agent of any entity at the Company's request,
unless the act or failure to act on the part of the director or officer giving
rise to the claim for indemnification is determined by a court in a final,
binding adjudication to have constituted willful misconduct or recklessness.

         24               Power of Attorney (see signature pages at pp. 7 - 8)

                  The Registrant hereby undertakes that the Plan and any
amendments thereto have been and will be submitted to the Internal Revenue
Service ("IRS") in a timely manner and all changes required by the IRS in order
to qualify the Plan under Section 401 of the Internal Revenue Code have been or
will be made.

Item 9.           Undertakings.

                  The undersigned Registrant hereby undertakes as follows:

                  (a) To file, during any period in which offers or sales are
being made pursuant to this Registration Statement, a post-effective amendment
to this Registration Statement:

                           (i) To include any prospectus required by Section
10(a)(3) of the Securities Act;

                           (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 aggregate,
represent a fundamental change in the information set forth in this 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 is registered) and any deviation from the low or high end of
the estimated maximum 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 20 percent change in the maximum
aggregate offering price set forth in "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 to such information in this
Registration Statement;

                                      -5-
provided, however, that paragraphs (i) and (ii) above 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 by the Registrant pursuant to Section 13 or
15(d) of the Exchange Act that are incorporated by reference in this
Registration Statement.

                  (b) That, for the purpose of determining any liability under
the Securities 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.

                  (c) 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.

                  The undersigned Registrant hereby undertakes that, for
purposes of determining any liability under the Securities Act, each filing of
the Registrant's annual report pursuant to Section 13(a) or 15(d) of the
Exchange Act 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 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 Securities 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 Securities Act and will be governed by the final
adjudication of such issue.
