<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt">B. The undersigned registrant hereby undertakes
that, for purposes of determining liability under the Securities Act, each filing of the Registrant&rsquo;s annual report pursuant
to Section&nbsp;13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan&rsquo;s annual
report pursuant to Section&nbsp;15(d) of the Exchange Act) that is incorporated by reference in the 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.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt">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 Securities and Exchange 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.</P>
