corporation. Section 145 of the Delaware General Corporation Law (the &ldquo;DGCL&rdquo;) provides that a corporation may 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&rsquo; fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection
with such action, suit or proceeding, provided that such person acted in good faith and in a manner 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 that his or her conduct was unlawful.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">This power to indemnify applies
to actions or suits brought by or in the right of the corporation to procure a judgment in its favor as well, but only to the extent of
expenses (including attorneys&rsquo; fees but excluding amounts paid in settlement) actually and reasonably incurred by the person in
connection with the defense or settlement of such action or suit if such person acted in good faith and in a manner reasonably believed
to be in, or not opposed to, the best interests of the corporation, 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
Delaware Court of Chancery or the court in which such action 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 shall deem proper.</P>

provides that to the extent a director or officer of a corporation has been successful in the defense of any action, suit or proceeding
referred to in subsections (a) and (b) of Section 145, or in the defense of any claim, issue or matter therein, he or she shall be indemnified
against expenses (including attorneys&rsquo; fees) actually and reasonably incurred by him or her in connection therewith; that indemnification
provided for by Section 145 shall not be deemed exclusive of any other rights to which the indemnified party may be entitled; and that
the corporation shall have power to purchase and maintain insurance on behalf of a director or officer of the corporation against any
liability asserted against him or her or incurred by him or her in any such capacity or arising out of his or her status as such whether
or not the corporation would have the power to indemnify him or her against such liabilities under Section 145.</P>

a director&rsquo;s duty of loyalty, for acts or omissions not in good faith or involving intentional misconduct or a knowing violation
of the law, for a transaction from which a director derives an improper personal benefit, or for liability arising under Section 174 of

registrant against expenses (including attorney&rsquo;s fees), judgments, fines and amounts paid in settlement, to the fullest extent

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

whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of

Note 1c. Pursuant to Rules 457(c) and (h) under the Securities Act, the proposed maximum offering price per share and the proposed maximum aggregate offering price are estimated for the purpose of calculating the amount of the registration fee and are based on the average of the high and low sales price of the Registrant's Common Stock as reported on the New York Stock Exchange on May 23, 2025.
