<p style=' margin-bottom:0pt; margin-top:0pt; text-indent:0.5in;text-align:left;'><b><font size=2>Dividend Reinvestment.  </font></b><font size=2>You may elect to reinvest cash dividends on all, some or none of your shares of Common Stock.  The Plan Administrator will use the cash dividends, from the shares that you elect reinvestment, to purchase shares of Common Stock that will be added to your Plan account (see Question 11).  We will pay cash dividends to you by check or direct deposit on shares that you do not select reinvestment.</font></p>

You may make optional cash investments by authorizing automatic monthly withdrawals from your bank account or by sending a check to the Plan Administrator at any time (see Question 12).</font></p>

If the shares are purchased on the open market, the price will be the weighted average price at which the Plan Administrator acquires the shares plus a brokerage commission and other fees.  If the shares are purchased directly from us, the price of the shares will be the average of the high and low sale prices on the applicable investment date (see Question 16).</font></p>

case of conduct in an official capacity, in the best interests of the corporation, and in all other cases, at least 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 proceedings by or in our right to procure judgment in our favor, no

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.</font></p>

<p style=' margin-bottom:5pt; margin-top:5pt; text-indent:0.33in;text-align:left;'><font size=2>Based on the foregoing and subject to the qualifications and limitations stated herein, I am of the opinion that the Shares are duly authorized and, when issued and delivered upon payment of the consideration therefore (not less than the par value of the Common Stock) in the manner contemplated in the Registration Statement, will be validly issued, fully paid and non-assessable.</font></p>

<p style=' margin-bottom:5pt; margin-top:5pt; text-indent:0.33in;text-align:left;'><font size=2>I am a member of the bar of the State of South Dakota.

<p style=' margin-bottom:5pt; margin-top:5pt; text-indent:0.33in;text-align:left;'><font size=2>I consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to me in the Prospectus constituting a part of the Registration Statement under the caption &#147;Legal Opinions.&#148; In giving this consent, I do not thereby admit that I am in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Securities and Exchange Commission promulgated thereunder. </font></p>
