          "Exchange Act") and the rules thereunder, and Form 144, pursuant to
          Rule 144 under the Securities Act of 1933, as amended (the "Securities

     2.   do and perform any and all acts for and on behalf of the undersigned
          which may be necessary or desirable to complete and execute any such
          Form 3, Form 4, Form 5 or Form 144 and timely file such form with the
          United States 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 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 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 might or
could do if personally present, with full power of substitution or revocation,
hereby ratifying and confirming all that such attorney-in-fact 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
attorney-in-fact, in serving in such capacity at the request of the undersigned,
is not assuming, nor is the Company assuming, any of the undersigned's
responsibilities to comply with Section 16(a) of the Exchange Act or Rule 144 of
the Securities Act.

          This Power of Attorney shall remain in full force and effect until the
undersigned is no longer a director of the Company unless earlier revoked by the
undersigned in a signed writing delivered to the foregoing attorneys-in-fact;
provided, however, this Power of Attorney will expire immediately upon the
termination of employment of any attorney-in-fact as to that attorney-in-fact
only, but not as to any other appointed attorney-in-fact hereunder.

          IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney
to be executed as of this 3rd day of December, 2012.
