ITEM 4. DESCRIPTION OF SECURITIES



Not Applicable.



ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL



Not Applicable.



ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS



Section 302A.521 of Minnesota Statutes requires the
Registrant to indemnify a person made or threatened to be made a party to a proceeding by reason of the former or present official
capacity of the person with respect to the Registrant, against judgments, penalties, fines, including, without limitation, excise
taxes assessed against the person



II-1

---

with respect to an employee benefit plan,
settlements and reasonable expenses, including attorneys fees and disbursements, incurred by the person in connection with
the proceeding, if such person (1) has not been indemnified by another organization or employee benefit plan for the same
judgments, penalties, fines, including, without limitation, excise taxes assessed against the person with respect to an employee
benefit plan, settlements, and reasonable expenses, including attorneys fees and disbursements, incurred by the person in
connection with the proceeding with respect to the same acts or omissions; (2) acted in good faith; (3) received no improper
personal benefit, and statutory procedure has been followed in the case of any conflict of interest by a director; (4) in the case
of a criminal proceeding, had no reasonable cause to believe the conduct was unlawful; and (5) in the case of acts or omissions
occurring in the persons performance in the official capacity of director or, for a person not a director, in the official
capacity of officer, committee member or employee, reasonably believed that the conduct was in the best interests of the
Registrant, or, in the case of performance by a director, officer or employee of the Registrant as a director, officer, partner,
trustee, employee or agent of another organization or employee benefit plan, reasonably believed that the conduct was not opposed
to the best interests of the Registrant. In addition, Section 302A.521, subd. 3, requires payment by the Registrant, upon written
request, of reasonable expenses in advance of final disposition in certain instances. A decision as to required indemnification is
made by a disinterested majority of the Board of Directors present at a meeting at which a disinterested quorum is present, or by
a designated committee of the Board, by special legal counsel, by the shareholders or by a court. The Registrants Bylaws
provide for indemnification of officers, directors, employees, and agents to the fullest extent provided by Section 302A.521.
Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended may be permitted to directors,
officers and controlling persons of the Registrant pursuant to the provisions referenced in Item 6 of this Registration Statement
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 the securities being registered hereunder, 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.



The Registrant also maintains directors and officers liability insurance.



ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED

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:

II-2

---

(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 this 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 this 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 Securities and Exchange 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 (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 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 this 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 in it, 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 (and, where
applicable, each filing of an employee benefit plan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 this Registration Statement shall be deemed to be a new
registration statement relating to the securities offered in it, 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 of 1933 may be permitted to directors, officers and controlling persons of the
Registrant, 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 of 1933 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 of 1933 and will be
governed by the final adjudication of such issue.
