    (other than an action by or in the right of the Registrant), by reason of the fact that he or she is or was a director or an officer of the Registrant. Such indemnification will cover all expenses (including attorneys&#8217; fees), judgments, fines and
    amounts paid in settlement actually and reasonably incurred by such person in connection therewith.</div>

  </div>
  <div style="text-indent: 36pt;">Subsection (a) of Section 145 of the DGCL empowers a corporation to 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 the 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, joint venture, trust or other enterprise, against expenses (including attorneys<font style="color: #000000;">&#8217;</font> fees), judgments, fines and amounts
    paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the 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 the person<font style="color: #000000;">&#8217;</font>s conduct was unlawful. The termination of any action, suit or proceeding by judgment, order,
    settlement, conviction, or upon a plea of <font style="font-style: italic; color: #000000;">nolo contendere</font> or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which the person
    reasonably believed to be in or not opposed to the best interest of the corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that the person<font style="color: #000000;">&#8217;</font>s conduct was unlawful.</div>
  <div><br>
  </div>
  <div style="text-indent: 36pt;">Subsection (b) of Section 145 of the DGCL empowers a corporation to 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 right of
    the corporation to procure a judgment in its favor by reason of the fact that such person acted in any of the capacities set forth above, against expenses (including attorneys<font style="color: #000000;">&#8217;</font> fees) actually and reasonably incurred
    by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation and except that no
    indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit
    was brought shall determine 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 indemnity for such expenses which the Court of Chancery or such
    other court shall deem proper.</div>
  <div><br>
  </div>
  <div style="text-indent: 36pt;">Subsection (d) of Section 145 of the DGCL provides that any indemnification under subsections (a) and (b) of Section 145 (unless ordered by a court) shall be made by the corporation only as authorized in the specific case
    upon a determination that indemnification of the present or former director, officer, employee or agent is proper in the circumstances because the person has met the applicable standard of conduct set forth in subsections (a) and (b) of Section 145.
    Such determination shall be made, with respect to a person who is a director or officer at the time of such determination, (1) by a majority vote of the directors who are not parties to such action, suit or proceeding, even though less than a quorum,
    or (2) by a committee of such directors designated by the majority vote of such directors, even though less than a quorum, or (3) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion, or (4)
    by the stockholders.</div>
  <div><br>
  </div>
  <div style="text-indent: 36pt;">Section 145 of the DGCL further provides that to the extent a present or former director or officer of a corporation has been successful on the merits or otherwise in the defense of any action, suit or proceeding referred
    to in subsections (a) and (b) of Section 145, or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys<font style="color: #000000;">&#8217;</font> fees) actually and reasonably incurred by
    such person in connection therewith and that such expenses may be paid by the corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such director or officer to repay such
    amount if it shall ultimately be determined that such person is not entitled to be indemnified by the corporation as authorized in Section 145 of the DGCL; that any indemnification and advancement of expenses provided by, or granted pursuant to,
    Section 145 shall not be deemed exclusive of any other rights to which the indemnified party may be entitled; that indemnification and advancement of expenses provided by, or granted pursuant to, Section 145 shall, unless otherwise provided when
    authorized or ratified, continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of such person<font style="color: #000000;">&#8217;</font>s heirs, executors and administrators; and empowers the
    corporation to purchase and maintain insurance on behalf of any person who 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, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person<font style="color: #000000;">&#8217;</font>s status as such,
    whether or not the corporation would have the power to indemnify such person against such liabilities under Section 145.</div>

  <div style="text-indent: 36pt;">(a) The undersigned Registrant hereby undertakes:</div>
  <div><br>
  </div>
  <div style="text-indent: 36pt;">(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:</div>
  <div><br>
  </div>
  <div style="text-indent: 36pt; margin-left: 36pt;">(i) to include any prospectus required by Section 10(a)(3) of the Securities Act;</div>
  <div><br>
  </div>
  <div style="text-indent: 36pt; margin-left: 36pt;">(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 SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
    price represent no more than 20% change in the maximum aggregate offering price set forth in the &#8220;Calculation of Registration Fee&#8221; table in the effective registration statement; and</div>
  <div><br>
  </div>
  <div style="text-indent: 36pt; margin-left: 36pt;">(iii) to include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this Registration
    Statement;</div>
  <div><br>
  </div>
  <div style="text-indent: 36pt;"><font style="font-style: italic;">provided</font>, <font style="font-style: italic;">however</font>, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective

    Exchange Act (and, where applicable, each filing of an employee benefit plan&#8217;s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in this Registration Statement shall be deemed a new registration statement

  </div>
  <div style="text-indent: 36pt;">(c) Insofar as indemnification for liabilities arising under the Securities Act 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 SEC 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, 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.</div>

Item 6.
Indemnification of Directors and Officers
.
Article 10 of the Registrant
'
s amended and restated bylaws requires the Registrant to indemnify and hold harmless, to the full extent permitted from time to time under the General
    Corporation Law of the State of Delaware (the "DGCL") each person who was or is a party to 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 Registrant), by reason of the fact that he or she is or was a director or an officer of the Registrant. Such indemnification will cover all expenses (including attorneys' fees), judgments, fines and
    amounts paid in settlement actually and reasonably incurred by such person in connection therewith.
Subsection (a) of Section 145 of the DGCL empowers a corporation to 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 the 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, joint venture, trust or other enterprise, against expenses (including attorneys
'
fees), judgments, fines and amounts
    paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the 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 the person
'
s conduct was unlawful. The termination of any action, suit or proceeding by judgment, order,
    settlement, conviction, or upon a plea of
nolo contendere
or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which the person
    reasonably believed to be in or not opposed to the best interest of the corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that the person
'
s conduct was unlawful.
Subsection (b) of Section 145 of the DGCL empowers a corporation to 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 right of
    the corporation to procure a judgment in its favor by reason of the fact that such person acted in any of the capacities set forth above, against expenses (including attorneys
'
fees) actually and reasonably incurred
    by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation and except that no
    indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit
    was brought shall determine 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 indemnity for such expenses which the Court of Chancery or such
    other court shall deem proper.
Subsection (d) of Section 145 of the DGCL provides that any indemnification under subsections (a) and (b) of Section 145 (unless ordered by a court) shall be made by the corporation only as authorized in the specific case
    upon a determination that indemnification of the present or former director, officer, employee or agent is proper in the circumstances because the person has met the applicable standard of conduct set forth in subsections (a) and (b) of Section 145.
    Such determination shall be made, with respect to a person who is a director or officer at the time of such determination, (1) by a majority vote of the directors who are not parties to such action, suit or proceeding, even though less than a quorum,
    or (2) by a committee of such directors designated by the majority vote of such directors, even though less than a quorum, or (3) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion, or (4)
    by the stockholders.
Section 145 of the DGCL further provides that to the extent a present or former director or officer of a corporation has been successful on the merits or otherwise in the defense of any action, suit or proceeding referred
    to in subsections (a) and (b) of Section 145, or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys
'
fees) actually and reasonably incurred by
    such person in connection therewith and that such expenses may be paid by the corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such director or officer to repay such
    amount if it shall ultimately be determined that such person is not entitled to be indemnified by the corporation as authorized in Section 145 of the DGCL; that any indemnification and advancement of expenses provided by, or granted pursuant to,
    Section 145 shall not be deemed exclusive of any other rights to which the indemnified party may be entitled; that indemnification and advancement of expenses provided by, or granted pursuant to, Section 145 shall, unless otherwise provided when
    authorized or ratified, continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of such person
'
s heirs, executors and administrators; and empowers the
    corporation to purchase and maintain insurance on behalf of any person who 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, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person
'
s status as such,
    whether or not the corporation would have the power to indemnify such person against such liabilities under Section 145.
As authorized by the Registrant's amended and restated bylaws, the Registrant may purchase and maintain at its expense on behalf of directors and officers insurance, within certain limits, covering liabilities which may be
    incurred by them in such capacities.
To the fullest extent permitted by the DGCL, the Registrant's amended and restated certificate of incorporation provides that a director or officer of the Registrant shall not be personally liable to the
    Registrant or its stockholders for monetary damages for breach of fiduciary duty as a director or officer.

Filed herewith
Pursuant to the instruction to Item 8 to Form S-8, no opinion of counsel as to the legality of the shares of Common Stock registered with respect to the Plan is furnished because no original issuance securities are being registered.
The Registrant undertakes to submit the Plan and any amendment thereto to the Internal Revenue Service ("IRS") in a timely manner and will make all changes required by the IRS in order to qualify the Plan.
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:
(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 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 SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
    price represent no more than 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and
(iii) to include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this Registration
    Statement;
provided
,
however
, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective
    amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement.
(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 undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 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 this Registration Statement shall be deemed a new registration statement
    relating to the securities offered therein, and the offering of such securities at that time shall be deemed 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 Registrant pursuant to the foregoing provisions, or otherwise, the
    Registrant has been advised that in the opinion of the SEC 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, 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.
SIGNATURES
Pursuant to the requirements of the Securities Act, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8, and has duly caused this Registration
    Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Bismarck, and State of North Dakota, on this 2
nd
