        (3) take any other action of any type whatsoever in connection with the
        foregoing which, in the opinion of such attorney-in-fact, may be of
        benefit to, in the best interest of, or legally required by, the
        undersigned, it being understood that the documents executed by such
        attorney-in-fact on behalf of the undersigned pursuant to this Power of
        Attorney shall be in such form and shall contain such terms and
        conditions as such attorney-in-fact may approve in such
        attorney-in-fact's discretion.

      The undersigned hereby grants to each such attorney-in-fact full power
      and authority to do and perform any and every act and thing whatsoever
      requisite, necessary, or proper to be done in the exercise of any of the
      rights and powers herein granted, as fully to all intents and purposes as
      the undersigned might or could do if personally present, with full power
      of substitution or revocation, hereby ratifying and confirming all that
      such attorney-in-fact, or such attorney-in-fact's substitute or

      to the undersigned's holdings of and transactions in securities issued by
      the Company, unless earlier revoked by the undersigned in a signed
      writing delivered to the foregoing attorneys-in-fact.


      IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to
      be executed as of February 22, 2024.

                                              /s/ Guy A. Metcalfe
