    2.  do and perform any and all acts for and on behalf of the undersigned
        which may be necessary or desirable to complete the execution of any

        (the "SEC") and any stock exchange, self-regulatory association or any
        other authority;

    3.  take any necessary or appropriate action to obtain or regenerate codes

    4.  take any other action of any type whatsoever in connection with the
        foregoing, which, in the opinion of the attorney-in-fact, may be of
        benefit to, in the best interest of, or legally required of, the
        undersigned, it being understood that the documents executed by the
        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 the attorney-in-fact may approve, in his discretion.

    The undersigned hereby grants to his attorney-in-fact full power and
authority to do and  perform all and every act and thing whatsoever requisite,
necessary and 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 the attorney-in-fact, or his substitute
or substitutes, shall lawfully do or cause to be done by virtue of this Power of
Attorney and the rights and powers herein granted. The undersigned acknowledges
that the foregoing attorney-in-fact, in serving in such capacity at the request
of the undersigned, is not assuming (nor is the Company nor its affiliates
assuming) any of the undersigned's responsibilities to comply with Section 16 of
the Act.

    This Power of Attorney shall remain in full force and effect until the

signed writing delivered to the foregoing attorney-in-fact. This Power of
Attorney does not revoke any other power of attorney that the undersigned has
previously granted.

    IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
executed as of this 18th day of March, 2019.
