Title of Securities Being Registered: Common Stock

No filing fee is due because of reliance on Section 24(f) of the Investment
Company Act of 1940.

This Registration Statement shall hereafter become effective in accordance with
Section 8(a) of the Securities Act of 1933. It is proposed that this filing will
become effective on Nov. 28, 2007.



Part A.

     Part A is incorporated by reference to that filed in Registrant's
     Pre-Effective Amendment No. 1 to Registration Statement No. 333-146689 on
     or about November 26, 2007.

Part B.

     Part B is incorporated by reference to that filed in Registrant's
     Pre-Effective Amendment No. 1 to Registration Statement No. 333-146689 on
     or about November 26, 2007.



PART C. OTHER INFORMATION

Item 15. Indemnification

The Articles of Incorporation of the registrant provide that the Fund shall
indemnify any person who was or is a party or is threatened to be made a party,
by reason of the fact that she or he is or was a director, officer, employee or
agent of the Fund, or is or was serving at the request of the Fund as a
director, officer, employee or agent of another company, partnership, joint
venture, trust or other enterprise, to any threatened, pending or completed
action, suit or proceeding, wherever brought, and the Fund may purchase
liability insurance and advance legal expenses, all to the fullest extent
permitted by the laws of the State of Minnesota, as now existing or hereafter
amended. The By-laws of the registrant provide that present or former directors
or officers of the Fund made or threatened to be made a party to or involved
(including as a witness) in an actual or threatened action, suit or proceeding
shall be indemnified by the Fund to the full extent authorized by the Minnesota
Business Corporation Act, all as more fully set forth in the By-laws filed as an
exhibit to this registration statement.

Insofar as indemnification for liability 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.

Any indemnification hereunder shall not be exclusive of any other rights of
indemnification to which the directors, officers, employees or agents might
otherwise be entitled. No indemnification shall be made in violation of the
Investment Company Act of 1940.

Item 17. Undertakings.

(1)       The undersigned registrant agrees that prior to any public reoffering
          of the securities registered through the use of a prospectus which is
          a part of this registration statement by any person or party who is
          deemed to be an underwriter within the meaning of Rule 145(c) of the
          Securities Act, the reoffering prospectus will contain the information
          called for by the applicable registration form for the reofferings by
          persons who may be deemed underwriters, in addition to the information
          called for by the other items of the applicable form.

(2)       The undersigned registrant agrees that every prospectus that is filed
          under paragraph (1) above will be filed as a part of an amendment to
          the registration statement and will not be used until the amendment is
          effective, and that, in determining any liability under the 1933 Act,
          each post-effective amendment shall be deemed to be a new registration
          statement for the securities offered therein, and the offering of the
          securities at that time shall be deemed to be the initial bona fide
          offering of them.

(3)       The Registrant undertakes to file by Post-Effective Amendment an
          Opinion of Counsel supporting the tax consequences of the proposed
