     period ended December 31, 2001, have been audited by the independent public
     accountants SyCip Gorres Velayo & Co., a member firm of Arthur Andersen,
     (referred to herein as Arthur Andersen). However, the Registrant has been
     unable to obtain the written consent of Arthur Andersen with respect to the
     incorporation by reference of such financial statements in this
     Registration Statements on Form S-8 (the "Registration Statement").
     Therefore, the Registrant has dispensed with the requirement to file the
     written consent of Arthur Andersen in reliance on Rule 437a under the
     Securities Act of 1933, as amended. As a result, you may not be able to
     recover damages from Arthur Andersen under Section 11 of the Securities Act
     of 1933, as amended, for any untrue statements of material fact or any
     omissions to state a material fact, if any, contained in the financial
     statements of the Registrant for the aforementioned financial statements,
     which are incorporated by reference in the Registration Statement.

ITEM 9. UNDERTAKINGS

(a)      Rule 415 Offering

         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 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.

         (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)      Filings incorporating subsequent Exchange Act documents by reference

         The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's or the Plan's annual report pursuant to section 13(a) or section
15(d) of the Exchange 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.

(h)      Request for acceleration of effective date or filing of registration
statement on Form S-8

         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 provisions described in Item 6 above, 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

                                                                             -3-

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.


                                                                             -4-

                  registration statement or any material change to such
                  information 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)      Filings incorporating subsequent Exchange Act documents by reference

         The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's or the Plan's annual report pursuant to section 13(a) or section
15(d) of the Exchange 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.

(h)      Request for acceleration of effective date or filing of registration
statement on Form S-8

         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 provisions described in Item 6 above, 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

                                                                             -3-
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.

                                                                             -4-

     fact, if any, contained in the financial statements of the Registrant for
