         any such person to release any such information to each of the
         undersigned's attorneys-in-fact appointed by this Power of Attorney and
         approves and ratifies any such release of information; and

    (4)  take any and 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 or for, 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 information and
         disclosure as such attorney-in-fact, in his or her 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,

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

Company, unless earlier revoked by the undersigned in a signed writing delivered
to the foregoing attorneys-in-fact.
