     All documents filed by the Company pursuant to Sections 13(a), 13(c), 14
and 15(d) of the Securities Exchange Act of 1934 (the "Exchange Act") after the
date hereof and prior to the filing of a post-effective amendment which

Item 6. Indemnification of Directors and Officers.

     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
connection with actions (including derivative actions) brought against such
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.

     No restricted securities are being reoffered or resold pursuant to this
Registration Statement.

Item 9. Undertakings

     The undersigned registrant hereby undertakes as follows:

          (1) 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:


                                       3


<PAGE>


               (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 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; and

               (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;


          (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.

     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 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
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.

Item 6. Indemnification of Directors and Officers.

     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
connection with actions (including derivative actions) brought against such
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.

     No restricted securities are being reoffered or resold pursuant to this
Registration Statement.

Item 9. Undertakings

     The undersigned registrant hereby undertakes as follows:

          (1) 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:

                                       3
(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 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; and

               (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;

          (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.

     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 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
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.
