(including amendments thereto), Form 144, or Schedule 13D or 13G (including

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 Limited 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 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 the acts such attorney-in-fact, or such
attorney-in-fact's substitute or substitutes, shall lawfully do or cause to be
done by virtue of this Limited Power of Attorney and the rights and powers
herein granted.  The undersigned acknowledges that each of the foregoing
attorneys-in-fact, in serving in such capacity at the request of the
undersigned, is not assuming any of the undersigned's responsibilities to comply
with Sections 13 or 16 of the Exchange Act or Rule 144 under the Securities Act.

The undersigned hereby revokes any and all prior powers of attorney executed for
this purpose.  This Limited Power of Attorney shall remain in full force and
effect until the undersigned is no longer required to file Forms 3, 4, and 5

amendments thereto) with respect 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 each of the foregoing
attorneys-in-fact.  In addition, at such time as any attorney-in-fact (i) ceases
to serve as an employee or counsel of the Company or any subsidiary of the
Company or (ii) resigns as attorney-in-fact by the execution of a written
resignation delivered to the undersigned or the Company, without any action on
the part of the undersigned, this Limited Power of Attorney shall be partially
revoked solely with respect to such individual; such individual shall cease to
be an attorney-in-fact under this Limited Power of Attorney; and the authority
of the other attorneys-in-fact then existing hereunder shall remain in full
force and effect.

IN WITNESS WHEREOF, the undersigned has caused this Limited Power of Attorney to
be executed as of this 15th day of October, 2018.
