    Act of 1934, as amended (the "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 the execution of any such Form 3, Form 4, Form 5
    or Form ID and the timely filing of such form with the

    stock exchange or similar authority; 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 such form and shall
    contain such terms and conditions as such attorney-in-fact
    may approve in his or her discretion.

    The undersigned hereby grants to each such attorney-in-fact
full power and authority to do and perform all 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,

substitution or revocation, hereby ratifying and confirming all
that such attorney-in-fact, or his substitute or substitutes,
shall lawfully do or cause to be done by virtue of his Power of
Attorney and the rights and powers herein granted. The

not assuming, nor is Agilent assuming, any of the undersigned's
responsibilities to comply with Section 16 of the Exchange Act.

     This Power of Attorney shall remain in full force and
effect until the undersigned is no longer required to file

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
