      (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 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  such  attorney-in-fact, acting
singly,  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 that 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 power of attorney and the
rights  and  powers  herein  granted.  The  undersigned  acknowledges  that  the
foregoing  attorneys-in-fact,  in serving in such capacity at the request of the
undersigned,  are  not  assuming,  nor  is  the  Company  assuming,  any  of the

to  indemnify the attorneys-in-fact and the Company from and against any demand,
damage,  loss,  cost or expense arising from any false or misleading information
provided by the undersigned to the attorneys-in-fact.

undersigned's  holdings of and transactions in securities issued by the Company,
unless  earlier  revoked by the undersigned in a signed writing delivered to the
foregoing  attorneys-in-fact.  This Power of Attorney supersedes any prior power
of  attorney  in connection with the undersigned's capacity as an officer and/or
director  of  the  Company.  This  Power  of  Attorney  shall  expire  as to any

officer of, or legal counsel to, the Company.

      IN  WITNESS  WHEREOF, the undersigned has caused this Power of Attorney to
be executed as of August 22, 2016.
