(2)    do and perform any and all acts for and on behalf of the undersigned that
may be necessary or desirable to complete and execute any such Documents and
timely file such Documents with the United States Securities and Exchange

(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

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

fact (or such attorney in fact's 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 each attorney in

delivering and filing Documents and agrees to reimburse the Company and such
attorney-in-fact for any legal or other expenses reasonably incurred in
connection with investigating or defending against any such loss, claim,
damage, liability or action.

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

unless earlier revoked by the undersigned in a signed writing delivered to each
of the foregoing attorneys in fact.

IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
executed as of this 27th day of January, 2020.
