         (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;

                           (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. 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 was registered) and any deviation
                                    from the low or high end of the estimated
                                    maximum offering 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 a 20% change in
                                    the maximum aggregate offering price set
                                    forth in the "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 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 Registration Statement is on Form S-3 or Form
                  S-8, 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 Section 15(d) of the Exchange Act that are incorporated
                  by reference in the Registration Statement.

                  (2)      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.

                  (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, each filing of the Registrant's annual report pursuant to
                  Section 13(a) or Section 15(d) of the Exchange Act (and, where
                  applicable, each filing of an employee benefit plan's annual
                  report pursuant to 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 in the initial
                  bona fide offering thereof.

         (c)      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
                  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 of 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.
