Company, as an Oklahoma corporation, is empowered by Section&nbsp;1031 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 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&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.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; background-color: white">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)&nbsp;any breach of the director&rsquo;s duty of loyalty to the
corporation or its shareholders, (ii)&nbsp;acts or omissions not in good faith or which involve intentional misconduct or a knowing violation
of law, (iii)&nbsp;payment of unlawful dividends or unlawful stock purchases or redemptions or (iv)&nbsp;any transaction from which the
director derived an improper personal benefit.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; background-color: white">Article VIII of the Company&rsquo;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)&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 quorum; (ii)&nbsp;by a committee of directors designated by a majority vote of directors, even though
less than a quorum; (iii)&nbsp;if there are no such directors, or if such directors so direct, by independent legal counsel in a written
opinion; or (iv)&nbsp;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&rsquo;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.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; background-color: white">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 &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>
