best interest of, or legally required by, the undersigned, it being understood
that the documents executed by such Attorney on behalf of the undersigned
pursuant to this Power of Attorney shall be in such form and shall contain such

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 serving in such
