       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

of the undersigned, are not assuming, nor is the Company assuming, any of the undersigned's
responsibilities to comply with Section 16 of the Exchange Act.

or acted upon such previously executed power of attorney documents and all other interested parties that the
undersigned withdraws every power and authority thereby given and declares such power of attorney
documents null and void and of no further force or effect.
       IN WITNESS WHEREOF, the undersigned has caused this Limited Power of Attorney to be
executed as of this 31st day of October, 2014.
