granted.  The undersigned acknowledges that the
foregoing attorneys-in-fact, in serving in such

The undersigned agrees that each such attorney-in-
fact may rely entirely on information furnished orally
or in writing by the undersigned to the attorneys-in-
fact. The undersigned also agrees to indemnify and
hold harmless the Company and each such attorney-in-
fact against any losses, claims, damages or
liabilities (or actions in these respects) that arise
out of or are based upon any untrue statements or
omissions of necessary facts in the information
provided by the undersigned to such attorneys-in-fact
for purposes of executing, acknowledging, delivering
or filing Form 3, 4 or 5, (including amendments
thereto) and agrees to reimburse the Company and the
attorneys-in-fact on demand for any legal or other
expenses reasonably incurred in connection with
investigating or defending against any such loss,
claim, damage, liability or action.

This 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 respect to the
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.

In Witness Whereof, the undersigned has caused this
Power of Attorney to be executed as of this 22nd day of
September, 2009.
