<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">Pursuant to section 145 of the Delaware General Corporation Law (the
&ldquo;DGCL&rdquo;), a corporation has the power to indemnify a party to any threatened, pending or completed legal proceeding by reason
of his or her service on behalf of a corporation. The DGCL further mandates that indemnification shall be made to any such person who
has been successful &ldquo;on the merits&rdquo; or &ldquo;otherwise&rdquo; with respect to the defense of any such proceeding, but does
not require indemnification in any other circumstances. The DGCL provides that a corporation has the power to indemnify a director, officer,
employee or agent of the corporation and certain other persons serving at the request of the corporation in related capacities against
amounts paid and expenses incurred in connection with an action or proceeding to which he or she is or is threatened to be made a party
by reason of such position, if such person has acted in good faith and in a manner he or she reasonably believed to be in or not opposed
to the best interests of the corporation, and, in any criminal proceeding, if such person had no reasonable cause to believe his or her
conduct was unlawful; provided that, in the case of actions brought by or in the right of the corporation, no indemnification may be made
with respect to any matter as to which such person has been adjudged to be liable to the corporation unless and only to the extent that
the adjudicating court determines that such indemnification is proper under the circumstances. A corporation may advance the expenses
incurred in defending such a proceeding upon the giving of an undertaking, or promise, to repay such sums in the event it is later determined
that such indemnitee is not entitled to be indemnified.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The Registrant&rsquo;s amended and restated certificate of incorporation
provides that the Registrant shall indemnify to the fullest extent permitted by section 145 of the DGCL each person that such section
grants the Registrant the power to indemnify and shall advance expenses incurred by an indemnified person in defending any civil, criminal,
administrative, or investigative action, suit or proceeding for which such indemnified person may be entitled to indemnification.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The Registrant also maintains insurance for its directors and officers
against certain liabilities, including liabilities under the&nbsp;Securities Act. The effect of this insurance is to indemnify any director
or officer of the Registrant against expenses, including, without limitation, attorneys&rsquo; fees, judgments, fines and amounts paid
in settlement, incurred by a director or officer upon a determination that such person acted in good faith. The premiums for such insurance
are paid by the Registrant.</P>

any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which

filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change

the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the&nbsp;Securities

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&nbsp;Securities
Act&nbsp;and will be governed by the final adjudication of such issue.</P>
