Minnesota Statutes Chapter 302A, the Minnesota Business Corporation Act (the &ldquo;Corporation Act&rdquo;). Section&nbsp;302A.521 of
the Corporation Act provides in substance that, unless prohibited by its articles of incorporation or bylaws, a corporation must indemnify
a person, including an officer or director, who is made or threatened to be made a party to a proceeding by reason of the former or present
official capacity of the person against 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&rsquo; fees and disbursements,
incurred by such person in connection with the proceeding, if certain criteria are met. These criteria, all of which must be met by the
person seeking indemnification, are (a)&nbsp;that such person 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&rsquo; fees and disbursements, incurred by the person in connection
with the proceeding with respect to the same acts or omissions; (b)&nbsp;that such person must have acted in good faith; (c)&nbsp;that
no improper personal benefit was obtained by such person and such person satisfied certain statutory conflicts of interest provisions,
if applicable; (d)&nbsp;that in the case of a criminal proceeding, such person had no reasonable cause to believe that the conduct was
unlawful; and (e)&nbsp;that, in the case of acts or omissions occurring in such person&rsquo;s performance in an official capacity, such
person must have acted in a manner such person reasonably believed was in the best interests of the corporation or, in certain limited
circumstances, not opposed to the best interests of the corporation. In addition, Section&nbsp;302A.521, subd. 3 requires payment by the
Company, upon written request, of reasonable expenses in advance of final disposition in certain instances. A decision as to required
indemnification is made by a majority of the disinterested board of directors present at a meeting at which a disinterested quorum is
present, or by a designated committee of disinterested directors, by special legal counsel, by the disinterested shareholders, or by a
court.</P>

Item 6.
Indemnification of Directors and Officers.
The Company is subject to
Minnesota Statutes Chapter 302A, the Minnesota Business Corporation Act (the "Corporation Act"). Section 302A.521 of
the Corporation Act provides in substance that, unless prohibited by its articles of incorporation or bylaws, a corporation must indemnify
a person, including an officer or director, who is made or threatened to be made a party to a proceeding by reason of the former or present
official capacity of the person against 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 such person in connection with the proceeding, if certain criteria are met. These criteria, all of which must be met by the
person seeking indemnification, are (a) that such person 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; (b) that such person must have acted in good faith; (c) that
no improper personal benefit was obtained by such person and such person satisfied certain statutory conflicts of interest provisions,
if applicable; (d) that in the case of a criminal proceeding, such person had no reasonable cause to believe that the conduct was
unlawful; and (e) that, in the case of acts or omissions occurring in such person's performance in an official capacity, such
person must have acted in a manner such person reasonably believed was in the best interests of the corporation or, in certain limited
circumstances, not opposed to the best interests of the corporation. In addition, Section 302A.521, subd. 3 requires payment by the
Company, upon written request, of reasonable expenses in advance of final disposition in certain instances. A decision as to required
indemnification is made by a majority of the disinterested board of directors present at a meeting at which a disinterested quorum is
present, or by a designated committee of disinterested directors, by special legal counsel, by the disinterested shareholders, or by a
court.
The Company also maintains a director and officer
insurance policy to cover the Company, its directors and its officers against certain liabilities.

Undertakings.
(a) The Company 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;
(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.
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 20 percent 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) above do not apply if the Registration Statement is on Form S-8,
and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished
to the Commission by the Company pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference
in this Registration Statement; and
(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 Company hereby undertakes that, for
purposes of determining any liability under the Securities Act, each filing of the Company's annual report pursuant to Section 13(a) or
15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of
the Exchange Act) 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 Company pursuant to the foregoing
provisions, or otherwise, the Company 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 Company of expenses incurred or paid by a director, officer or controlling person
of the Company 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 Company 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.
