  action or proceeding, had no reasonable cause to believe his conduct was unlawful. However, in an action by or in the right of the Company,
  Section&nbsp;1031 prohibits indemnification if such person is adjudged to be liable to the Company, unless such indemnification is allowed
  by a court of competent jurisdiction. The statute provides that indemnification pursuant to its provisions is not exclusive of other rights
  of indemnification to which a person may be entitled under any bylaw, agreement, vote of shareholders, or disinterested directors, or

  the specified director or officer to the fullest extent permitted by law. The agreements provide that, upon request by a director or officer,
  the Company is obligated to advance expenses for defense of a claim made against the director or officer. The obligation of the Company
  to indemnify the director or officer is subject to applicable law and the determination by a &ldquo;reviewing party&rdquo; selected by
  the board of directors that the director or officer is entitled to indemnification. In addition, the agreements obligate the Company to
  indemnify the specified officer or director to the extent of the Company&rsquo;s recoveries under insurance policies regardless of whether
  the director or officer is ultimately determined to be entitled to indemnification. The agreements also provide for partial indemnification
  if a portion of a claim for indemnification is not allowed by the reviewing party appointed by the board of directors.</P>

  Item 6.
  Indemnification of Directors and Officers.
  The
  Company, as an Oklahoma corporation, is empowered by Section 1031 of the Oklahoma General Corporation Act, subject to the procedures
  and limitations stated therein, to indemnify any person against expenses (including attorneys' fees), judgments, fines and amounts
  paid in settlement actually and reasonably incurred by him in connection with any threatened, pending or completed action, suit or proceeding
  (whether civil, criminal, administrative or investigative) in which such person is made or threatened to be made a party by reason of
  the person being or having been a director, officer, employee or agent of the Company or is or was serving at its request as a director,
  officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, if the person acted in good
  faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Company, and with respect to any criminal
  action or proceeding, had no reasonable cause to believe his conduct was unlawful. However, in an action by or in the right of the Company,
  Section 1031 prohibits indemnification if such person is adjudged to be liable to the Company, unless such indemnification is allowed
  by a court of competent jurisdiction. The statute provides that indemnification pursuant to its provisions is not exclusive of other rights
  of indemnification to which a person may be entitled under any bylaw, agreement, vote of shareholders, or disinterested directors, or
  otherwise.
  The certificate of incorporation of the Company
  provides that a director of the corporation shall not be personally liable to the corporation or its shareholders for monetary damages
  for breach of fiduciary duty as a director, except for liability for (i) any breach of the director's duty of loyalty to the
  corporation or its shareholders, (ii) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation
  of law, (iii) payment of unlawful dividends or unlawful stock purchases or redemptions or (iv) any transaction from which the
  director derived an improper personal benefit.
  Article VIII of the Company's bylaws
  provides that directors and officers of the Company shall be indemnified by the Company to the fullest extent permitted by the Oklahoma
  General Corporation Act, including the advance of related expenses. Pursuant to Article VIII of the bylaws of the Company, upon authorization
  and determination (i) by the board of directors by a majority vote of the directors who were not parties to such action, suit or
  proceeding, even though less than quorum; (ii) by a committee of directors designated by a majority vote of directors, even though
  less than a quorum; (iii) if there are no such directors, or if such directors so direct, by independent legal counsel in a written
  opinion; or (iv) by the shareholders, the Company is obligated to indemnify any person who incurs liability by reason of the fact
  that he is or was a director, officer, employee or agent of the Company, or is or was serving at its request as a director, officer, employee
  or agent of another corporation, partnership, limited liability company, joint venture, trust or other enterprise, or as a member of any
  committee or similar body, 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 Company, and with respect to any criminal action or proceeding, had no reasonable cause to believe the person's
  conduct was unlawful. However, in an action, suit or proceeding by or in the right of the Company, no indemnification will be made if
  such person shall be adjudged to be liable to the Company, unless such indemnification is allowed by a court of competent jurisdiction.
  The Company has entered into indemnification
  agreements with certain of its directors and officers. These indemnification agreements provide that the Company is obligated to indemnify
  the specified director or officer to the fullest extent permitted by law. The agreements provide that, upon request by a director or officer,
  the Company is obligated to advance expenses for defense of a claim made against the director or officer. The obligation of the Company
  to indemnify the director or officer is subject to applicable law and the determination by a "reviewing party" selected by
  the board of directors that the director or officer is entitled to indemnification. In addition, the agreements obligate the Company to
  indemnify the specified officer or director to the extent of the Company's recoveries under insurance policies regardless of whether
  the director or officer is ultimately determined to be entitled to indemnification. The agreements also provide for partial indemnification
  if a portion of a claim for indemnification is not allowed by the reviewing party appointed by the board of directors.
  The Company provides liability insurance for
  its directors and officers which provides for coverage against loss from claims made against officers and directors in their capacity
  as such, including, subject to certain exceptions, liabilities under the federal securities laws.
  It is recognized that the above-summarized
  provisions of the Company's bylaws, the indemnification agreements and the applicable provisions of the Oklahoma General Corporation
  Act may be sufficiently broad to indemnify officers, directors and controlling persons of the Company against liabilities arising under
  such act.

  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 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 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 SEC 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 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) of this section 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 Company pursuant to Section 13 or 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; and
  (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 further undertakes that, for the 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 that is incorporated by reference in this 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 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 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.
