        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 attorney-in-fact full power and
       authority to do and perform all and every act and thing whatsoever
       requisite, necessary and proper to be done in the exercise of any of the

       as the undersigned might or could do if personally present, with full
       power of substitution or revocation, hereby ratifying and confirming all

       undersigned acknowledges that the foregoing attorneys-in-fact, in serving
       in such capacity at the request of the undersigned, are not assuming, nor

       of 1934 or Rule 144 of the Securities Act of 1933.

       delivered to the foregoing attorneys-in-fact. This Power of Attorney
       shall supersede any and all existing Powers of Attorney with respect to
       the subject matter hereof.

IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
executed as of this 20th day of February, 2014.
