ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Registrant is incorporated under the laws of the State of Delaware.
Section 145 ("Section 145") of the General Corporation Law of the State of
Delaware, as the same exists or may hereafter be amended (the "General
Corporation Law"), inter alia, provides that a Delaware corporation may
indemnify any persons who were, are or are threatened to be made, parties to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of such corporation), by reason of the fact that such person is or was an
officer, director, employee or agent of such corporation, or is or was serving
at the request of such corporation as a director, officer, employee or agent of
another corporation or enterprise. The indemnity may include expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by such person in connection with such action, suit or
proceeding, provided such person acted in good faith and in a manner he
reasonably believed to be in or not opposed to the corporation's best interests
and, with respect to any criminal action or proceeding, had no reasonable cause
to believe that his conduct was illegal.

         Section 145 further authorizes a corporation to purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee or
agent of the corporation, or is or was serving at the request of the corporation
as a director, officer, employee or agent of another corporation or enterprise,
against any liability asserted against him and incurred by him in any such
capacity, arising out of his status as such, whether or not the corporation
would otherwise have the power to indemnify him under Section 145.

         Registrant's Bylaws, as amended, provide for the indemnification of
officers and directors to the fullest extent permitted by the General
Corporation Law.

         All of Registrant's directors and officers will be covered by insurance
policies maintained by Registrant against certain liabilities for actions taken
in their capacities as such, including liabilities under the Securities Act of
1933, as amended.

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 of
                                    1933;

                           (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;

                           (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 Satement;

                  Provided, however that paragraphs (a)(1)(i) and (a)(1)(ii) do
                  not apply if the registration statement is on Form S-3, Form
                  S-8 or Form F-3, and 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 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
                  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 (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 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.


                                   SIGNATURES

         Pursuant to the requirements of the Securities Act of 1933, the
Registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-8 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of St. Paul, and State of Minnesota on December 10,
2002.
