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 statement;

          provided,  however,  that paragraphs  (a)(l)(i) and (a)(l)(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  of 1934 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 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  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 Securities  and Exchange  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  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.

   Pursuant to the  requirements  of the  Securities Act of 1933, the registrant

requirements for filing on Form S-8 and has duly caused this to be signed on its
behalf by the undersigned, thereunto duly authorized, in the City of Rapid City,
State of South Dakota, on the 13th day of July, 1999.
