            (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 this Registration
                Statement (or the most recent post-effective amendment thereto)
                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 (1)(i) and (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 Section 15(d) 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 that
            remain unsold at the termination of the offering.


                                      II-2
   4
            (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 Section 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.

            (c) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Registrant, 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.

Registration Statement to be signed on its behalf by the undersigned, thereunto
duly authorized, in the City of Phoenix, State of Arizona, on April 6, 2001.
