        collectively, the "Reports"): (a) Forms 3, 4 and 5, including any
        amendments thereto, and any other report required pursuant to Section

        and in my name, any and all applications, certificates, consents,
        instruments, verifications, exhibits, schedules, or other ancillary

        ability to file, any Report (including, without limitation, the EDGAR
        Form ID or any other form of application or request for Securities and
        Exchange Commission ("SEC") filing codes and/or the modification,
        renewal or replacement of such codes, including CIK, CCC, or the like,

        thereto, in such form, with such changes and modifications therein, and
        additions thereto, as such attorney-in-fact executing the same may
        approve, such approval to be conclusively evidenced by his or her
        execution thereof;

    (3) Perform on my behalf, and in my name, any and all acts of any kind or
        description whatsoever, as may be in any way necessary or desirable to
        complete and execute any Reports and timely file such Reports with the
        SEC and/or any stock exchange or similar authority; and

    (4) Take any and all other or further action in connection with the
        foregoing that, 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 any document executed by such
        attorney-in-fact on my behalf 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 his or her discretion.

    I grant to each such attorneys-in-fact full power and authority to do and
perform any act 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 I
might or could do if personally present, with full power of substitution or
revocation.  I ratify and confirm all that such attorney-in-fact, or any
substitute of such attorney-in-fact, shall lawfully do or cause to be done by
the rights and powers granted by this Power of Attorney.

    I acknowledge that each such attorney-in-fact, in serving in such capacity
at my request, is not assuming, nor is the Company assuming, any of my
responsibilities to comply with Section 16 of the Exchange Act, Rule 144 under
the Securities Act or applicable federal or state securities laws generally.

    This Power of Attorney shall remain in full force and effect until I am no
longer required to file any Reports with respect to my holdings of and
transactions in securities issued by the Company, unless I earlier revoke it in
a signed writing delivered to the Office of the Corporate Secretary of the
Company.

    IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
executed as of this 30th day of November, 2017
