  of the Oklahoma General Corporation Act, subject to the procedures and limitations stated therein, to indemnify any person against expenses
  (including attorneys&rsquo; 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 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&rsquo;s
  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 otherwise.</P>

  (ii)&nbsp;acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii)&nbsp;payment

  (i)&nbsp;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 a quorum; (ii)&nbsp;by a committee of directors designated by a majority vote of directors, even though less than a quorum;

  another corporation, partnership, limited liability company, joint venture, trust or other enterprise, or as a member of any committee

  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 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 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 a 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 the person 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.
  II-
  2
  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.
  Item 7.
  Exemption from Registration Claimed.
  Not applicable.
  Item 8.
  Exhibits.
  A list of exhibits filed herewith is contained in the Exhibit Index
  that immediately precedes such exhibits and is incorporated herein by reference.
  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 the 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 a prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
  price represent no more than a 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)
  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 registrant pursuant to Section 13
  or Section 15(d) of the Exchange Act that are incorporated by reference into this Registration Statement.
  II-
  3
  (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 will 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 into this Registration
  Statement will be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities
  at that time will 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 registrant pursuant
  to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the 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 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.
