ITEM 5.  Interests of Named Experts and Counsel

ITEM 6.  Indemnification of Directors and Officers

         The Company's Restated Articles of Incorporation provide that the Company may indemnify the agents of

prohibit the Company from terminating its indemnification obligations as to acts or omissions of any director or
executive officer occurring before the termination.  The indemnification and limitations on liability permitted
by the Restated Articles of Incorporation and the agreements are subject to the limitations set forth by

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;

                                    (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;

2


                                    (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
                           Section 15(d) of the Exchange Act that are incorporated by reference in this
                           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 that 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 each filing of the Plan's annual report pursuant to Section 15(d) of the Exchange
Act 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.

         (c)      The undersigned Registrant hereby undertakes that the Registrant has submitted or will submit
the Plan and any amendment thereto to the Internal Revenue Service ("IRS") in a timely manner and has made or
will make all changes required by the IRS in order to qualify the Plan.

         (d)      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 Securities 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 Securities Act and will be governed by the final adjudication of such
issue.
