    The undersigned acknowledges that:

    a)   This Limited Power of Attorney authorizes, but does not require, the

         such Attorney-in-Fact without independent verification of such
         information;

    b)   Any documents prepared or executed by the Attorney-in-Fact on behalf of
         the undersigned pursuant to this Limited Power of Attorney will be in
         such form and will contain such information as the Attorney-in-Fact, in
         his discretion, deems necessary or desirable;

    c)   Neither the Company nor the Attorney-in-Fact assumes any liability for
         the undersigned's responsibility to comply with the requirements of
         Section 16 of the Exchange Act or Rule 144, any liability of the
         undersigned for any failure to comply with such requirements, or any
         liability of the undersigned for disgorgement of profits under Section
         16(b) of the Exchange Act; and

    d)   This Limited Power of Attorney does not relieve the undersigned from
         responsibility for compliance with the undersigned's obligations under
         Section 16 of the Exchange Act, including, without limitation, the
         reporting requirements under Section 16 of the Exchange Act.

      The undersigned hereby grants to the Attorney-in-Fact full power and
authority to do and perform each and every act and thing requisite, necessary or
advisable to be done in connection with the foregoing, as fully, to all intents
and purposes, as the undersigned might or could do in person, hereby ratifying
and confirming all that each Attorney-in-Fact, or his substitute or substitutes,
shall lawfully do or cause to be done by authority of this Limited Power of
Attorney. This Limited Power of Attorney shall remain in full force and effect
until the undersigned is no longer required to file Forms 3, 4 or 5 or Forms 144
with respect to the undersigned's holdings of and transactions in securities of
the Company, unless earlier revoked by the undersigned in a signed writing
delivered to the Attorney-in-Fact. This Limited Power of Attorney revokes all
previous powers of attorney with respect to the subject matter of this Limited
Power of Attorney.

    IN WITNESS WHEREOF, the undersigned has signed this Limited Power of
Attorney as of April 8, 2021.
