faith and in a manner that person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe such conduct was unlawful.  With respect to actions or suits by or in the right of the corporation, the statute provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending, or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that that person is or was a director, officer, employee, or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee, or agent of another corporation, partnership, limited liability company, joint venture, trust, or other enterprise against expenses, including attorneys&#146; fees, actually and reasonably incurred by that person in connection with the
defense or settlement of such action or suit if that person acted in good faith and in a manner that person reasonably believed to be in or not opposed to the best interest of the corporation and except that no indemnification may be made in respect of any claim, issue, or matter as to which such person has been adjudged to be liable for negligence or misconduct in the performance of such duty to the corporation unless and only to the extent that the court in which such action or suit was brought determines upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnification for such expenses which the court deems proper.  </font></p>

Item 6.
INDEMNIFICATION OF DIRECTORS AND OFFICERS
Section 47-2-58.2 of the South Dakota Codified Laws provides generally that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending, or completed action, suit, or proceeding, whether civil, criminal, administrative, or investigative, other than an action by or in the right of the corporation, by reason of the fact that that person is or was a director, officer, employee, or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee, or agent of another corporation, partnership, limited liability company, joint venture, trust, or other enterprise, against expenses, including attorneys' fees, judgments, fines, and amounts paid in settlement actually and reasonably incurred by that person in connection with such action, suit, or proceeding if that person acted in good
faith and in a manner that person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe such conduct was unlawful.  With respect to actions or suits by or in the right of the corporation, the statute provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending, or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that that person is or was a director, officer, employee, or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee, or agent of another corporation, partnership, limited liability company, joint venture, trust, or other enterprise against expenses, including attorneys' fees, actually and reasonably incurred by that person in connection with the
defense or settlement of such action or suit if that person acted in good faith and in a manner that person reasonably believed to be in or not opposed to the best interest of the corporation and except that no indemnification may be made in respect of any claim, issue, or matter as to which such person has been adjudged to be liable for negligence or misconduct in the performance of such duty to the corporation unless and only to the extent that the court in which such action or suit was brought determines upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnification for such expenses which the court deems proper.
The Bylaws of the Company provide that the Company shall indemnify any officer or director who acted in a manner which such person reasonably believed to be within the scope of such person's authority against liability incurred by such person to the same extent and under the same circumstances as are currently permitted under the South Dakota Codified Laws.  In addition, the Company has entered into specific agreements with the directors and officers of the Company providing for indemnification of such persons under certain circumstances.
The Company's Articles of Incorporation also eliminate the liability of the Company's directors for monetary damages for breach of their fiduciary duty as directors.  This provision, however, does not eliminate a director's liability (a) for any breach of the director's duty of loyalty to the Company or its shareholders, (b) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (c) for any violation of Sections 47-5-15 to 47-5-19, inclusive, of the South Dakota Codified Laws, which relate in part to certain unlawful dividend payments or stock redemptions or repurchases, or (d) for any transaction from which the director derived an improper personal benefit.
The Company carries directors' and officers' liability insurance to insure its directors and officers against liability for certain errors and omissions and to defray costs of a suit or proceeding against an officer or director.

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 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 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.
