                               POWER OF ATTORNEY

      KNOW ALL BY THESE PRESENTS, that the undersigned hereby constitutes and

     "Exchange Act"), and the rules thereunder;

     (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, 4 or 5, complete and execute any amendments thereto, and timely file
     such form with theU.S. Securities and Exchange Commission (the "SEC"),
     including without limitation the filing of a Form ID or any other documents
     necessary or appropriate to enable the undersigned to file the Forms 3, 4
     and 5 electronically with the SEC; 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

    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

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

fact, in serving in such capacity at the request of the undersigned, are not
