     Reference  is made to the Power of  Attorney,  dated  June 22, 2003 (the
"POA"),  pursuant to which Claes Dahlback (the "Reporting  Person") appointed
the undersigned,  as well as Saskia Brookfield Martin (and any other employee
of The Goldman Sachs Group,  Inc. or one of its affiliates  (the "Firm")
designated in writing by one of the  attorneys-in-fact), one of the Reporting
Person's lawful attorneys  with  power  to act  without  the  other,  and  with
full  power  of substitution and  resubstitution,  to, among other things,
execute and file for the Reporting Person and in the Reporting Person's name
any Statement of Changes in  Beneficial  Ownership  on Form 4 and any  Annual
Statement  of  Changes  in Beneficial  Ownership on Form 5, or any similar or
successor form,  which may be required  to be filed by the  Reporting  Person
with  the U.S.  Securities  and Exchange  Commission  pursuant to Section 16 of
the  Securities  Exchange Act of 1934, as amended.

     Pursuant to the  authority  set forth in the POA,  the  undersigned  hereby
designates  Kenneth L. Josselyn,  Beverly L. O'Toole and Benjamin J. Rader, each

same  authority  to  act as  was  provided  to the  undersigned  and  the  other
attorneys-in-fact in the POA.

     This Designation of Additional Attorneys-in-Fact (this "Designation") shall

this Designation  shall be affected by the subsequent  disability or
incompetence of the Reporting  Person.  This  Designation  shall remain in full
force and effect until either it or the POA is revoked in writing by the

Designation cease to be employees of the Firm.

     IN WITNESS thereof the  undersigned  hereunto signed his name this 22nd day
of September 2005.
