Item 4.   Description of Securities.

          Not applicable.


                                      II-3




Item 5.   Interests of Named Experts and Counsel.

          Not applicable.


Item 6.   Indemnification of Directors and Officers.

          Subchapter D (Sections 1741 through 1750) of Chapter 17 the
Pennsylvania Business Corporation Law of 1988 (the "BCL") contains provisions
for mandatory and discretionary indemnification of a corporation's directors,
officers, employees and agents (collectively "Representatives"), and related
matters.

          Under Section 1741, subject to certain limitations, a corporation has
the power to indemnify directors, officers and other Representatives under
certain prescribed circumstances against expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
in connection with a threatened, pending or completed action or proceeding,
whether civil, criminal, administrative or investigative, to which any of them
is a party or threatened to be made a party by reason of his being a
Representative of the corporation or serving at the request of the corporation
as a Representative of another corporation, partnership, joint venture, trust or
other enterprises, if he acted in good faith and in a manner he reasonably
believed to be in, or not opposed to, the best interests of the corporation and,
with respect to any criminal proceeding, had no reasonable cause to believe his
conduct was unlawful.

          Section 1742 provides for indemnification with respect to derivative
actions similar to that provided by Section 1741. However, indemnification is
not provided under Section 1742 in respect to any claim, issue or matter as to
which a Representative has been adjudged to be liable to the corporation unless
and only to the extent that the proper court determines upon application that,
despite the adjudication of liability but in view of all the circumstances of
the case, the Representative is fairly and reasonably entitled to indemnity for
the expenses that the court deems proper.

          Section 1743 provides that indemnification against expenses is
mandatory to the extent that a Representative has been successful on the merits
or otherwise in defense of any such action or proceeding referred to in Section
1741 or 1742.

          Section 1744 provides that unless ordered by a court, any
indemnification under Section 1741 or 1742 shall be made by the corporation as
authorized in the specific case upon a determination that indemnification of a
Representative is proper



                                      II-4




because the Representative met the applicable standard of conduct, and such
determination will be made by the board of directors by a majority vote of a
quorum of directors not parties to the action or proceeding; if a quorum is not
obtainable or if obtainable and a majority of disinterested directors so
directs, by independent legal counsel in a written opinion; or by the
shareholders.

          Section 1745 provides that expenses incurred by a Representative in
defending any action or proceeding referred to in Subchapter D of Chapter 17 of
the BCL may be paid by the corporation in advance of the final disposition of
such action or proceeding upon receipt of an undertaking by or on behalf of the
Representative to repay such amount if it shall ultimately be determined that he
is not entitled to be indemnified by the corporation.

          Section 1746 provides generally that except in any case where the act
or failure to act giving rise to the claim for indemnification is determined by
a court to have constituted willful misconduct or recklessness, the
indemnification and advancement of expenses provided by Subchapter D of Chapter
17 of the BCL shall not be deemed exclusive of any other rights to which a
Representative seeking indemnification or advancement of expenses may be
entitled under any bylaw, agreement, vote of shareholders or disinterested
directors or otherwise, both as to action in his official capacity and as to
action in another capacity while holding that office.

          Section 1747 grants a corporation the power to purchase and maintain
insurance on behalf of any Representative against any liability incurred by him
in his capacity as a Representative, whether or not the corporation would have
the power to indemnify him against that liability under Subchapter D of Chapter
17 of the BCL.

          Sections 1748 and 1749 apply the indemnification and advancement of
expenses provisions contained in Subchapter D of Chapter 17 of the BCL to
successor corporations resulting from consolidation, merger or division and to
service as a representative of a corporation or an employee benefit plan.

          Section 7-2 of the Registrant's Bylaws provides that the Registrant
will indemnify any director or officer of the Registrant to the fullest extent
permitted by Pennsylvania Law against all expense, liability and loss reasonably
incurred or suffered by such person in connection with any threatened, pending
or completed action, suit or proceeding (a "Proceeding") involving such person
by reason of the fact that he or she is or was a director or officer of the
Registrant or is or was serving


                                      II-5




at the request or for the benefit of the Registrant in any capacity for another
corporation or other enterprise. No indemnification pursuant to Section 7-2 may
be made, however, in any case where the act or failure to act giving rise to the
claim for indemnification is determined by a court to have constituted willful
misconduct or recklessness.

          Section 7-2 further provides that the right to indemnification
includes the right to have the expenses incurred by the indemnified person in
defending any Proceeding paid by the Registrant in advance of the final
disposition of the Proceeding to the fullest extent permitted by Pennsylvania
Law. In addition, Section 7-2 provides that the Registrant may purchase and
maintain insurance for the benefit of any person on behalf of whom insurance is
permitted to be purchased by Pennsylvania Law against any expense, liability or
loss whether or not the Registrant would have the power to indemnify such person
under Pennsylvania or other law. The Registrant may also purchase and maintain
insurance to insure its indemnification obligations, whether arising under the
Bylaws or otherwise. In addition, Section 7-2 states that the Registrant may
create a fund of any nature or otherwise may secure in any manner its
indemnification obligations, whether arising under the Bylaws or otherwise.

          Section 7-3 of the Registrant's Bylaws states that the provisions of
the Bylaws relating to indemnification constitute a contract between the
Registrant and each of its directors and officers which may be modified as to
any director or officer only with that person's consent or as provided in
Section 7-3. Further, any repeal or amendment of the indemnification provisions
of the Bylaws adverse to any director or officer will apply only on a
prospective basis. In addition, no repeal or amendment of the Bylaws may affect
the indemnification provisions of the Bylaws so as to reduce or limit
indemnification or the advancement of expenses in any manner unless adopted by
(a) the unanimous vote of the directors of the Registrant then serving or (b)
the affirmative vote of shareholders entitled to cast at least 80% of the votes
that all shareholders are entitled to cast in the election of directors,
provided that no such amendment will have a retroactive effect inconsistent with
the preceding sentence.

          Subsection 2(j) of the Plan provides that the Registrant will
indemnify and hold harmless to the maximum extent permitted by its Bylaws
officers and directors who exercise any discretionary authority or discretionary
control respecting management of the Plan or exercise any authority or control
with respect to management or disposition of the Plan's assets, or who have any
discretionary authority or discretionary responsibility in the administration of
the Plan.


                                      II-6




          The Registrant has purchased directors and officers liability
insurance for its directors and officers.

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:

                    (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 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;

                    (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) do not apply, if 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)


                                      II-8




of the Securities Exchange Act of 1934 that are incorporated by reference in the
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.

          (b) The undersigned registrant hereby 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 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.

          (h) 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 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.


                                      II-9
