(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 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 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 power of attorney and the rights and powers herein granted.
The undersigned acknowledges that the foregoing attorneys-in-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
Securities Exchange Act of 1934.

     The undersigned agrees that each such attorney-in-fact herein
may rely entirely on information furnished orally or in writing by
the undersigned to such attorney-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

for purposes of executing, acknowledging, delivering or filing
Forms 3, 4 or 5 (including amendments thereto) or Form ID and
agrees to reimburse the Company and such attorney-in-fact for any
legal or other expenses reasonably incurred in connection with

liability or action.

     This Power of Attorney supersedes any power of attorney

outlined in the first paragraph hereof ("Prior Powers of
Attorney"), and the authority of the attorneys-in-fact named in
any Prior Powers of Attorney is hereby revoked.

     This Power of Attorney shall remain in full force and effect
until the undersigned is no longer required to file Forms 3, 4
or 5 with respect to the undersigned's holdings of and
transactions in securities issued by the Company, unless earlier

the foregoing attorneys-in-fact or (b) superseded by a new power
of attorney regarding the purposes outlined in the first
paragraph hereof dated as of a later date.

     IN WITNESS WHEREOF, the undersigned has caused this Power
of Attorney to be executed as of this 16th day of October, 2008.
