        Securities and Exchange Commission and any stock exchange or similar
        authority; and

(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 of, 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 such attorney-in-fact full power
and authority to do and perform any and every act and thing whatsoever requisit,
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 limited power of attorney and all rights and powers

fact, in serving in such capacity at the request of the undersigned, are not
assuming, nor is the Company assuming, any of the undersigned's responsibilities
to comply with Section 16 of the Act.

       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 with

by, the Company, unless earlier revoked by the undersigned in a signed writing
delivered to the foregoing attorneys-in-fact.

       IN WITNESS WHEREOF, the undersigned has caused this limited power of
attorney to be executed as of this 9th of March, 2015.
