Exchange Act of 1934, prior to the filing of a post-effective amendment which

Item 6.  Indemnification of Directors and Officers.

     The registrant's amended and restated articles of incorporation contain a

breaches of the director's duty of loyalty, (b) acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of the law,
(c) certain acts specified by Colorado law, and (d) transactions from which the
director derives an improper benefit.

     Colorado law also grants corporations incorporated under the laws of
Colorado the right to indemnify their directors, officers, employees and agents
in accordance with the provisions thereof. The registrant's amended and restated
articles of incorporation provide for extensive indemnification of the
registrant's directors, officers, employees and agents.

Item 9.  Undertakings.

     The 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 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 (I) and (II) above do not apply if the
     registration statement is on Form S-3, Form S-8 or Form F-3, and the
     information required to be included in a post-effective amendment by those
     paragraphs is contained in periodic reports filed with or furnished to the
     Commission 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.


                                       5






     (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.

     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.

     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 foregoing provisions, 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 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.

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 Colorado Springs, State of Colorado, on December 6,
2004.
