This  Amendment No. 6  supplementally  amends the initial  statement on Schedule

terms used but not defined  herein shall have the  meanings  ascribed to them in
the  Initial  Statement.  The Initial  Statement  is  supplementally  amended as
follows.


Item 2.   Identity and Background.


        This Statement is being filed on behalf of each of the following persons
(collectively, the "Reporting Persons"):

                  i)       Quantum Industrial Partners LDC ("QIP");

                  v)       Mr. George Soros ("Mr. Soros").


                  This Statement relates to Shares held for the accounts of QIP
and SFM Domestic Investments LLC ("SFM Domestic Investments").

                  On December 27, 2002, Mr. Soros appealed a decision of the 11e
Chambre du Tribunal  Correctionnel in Paris, France that fined him $2.28 million
on  December  20,  2002 based on a finding of insider  trading  with  respect to
trading in  securities  of Societe  Generale in 1988.  Mr.  Soros has elected to
provide the foregoing information on a voluntary basis.

Item 5.   Interest in Securities of the Issuer.

          (a)     (i)  Each of QIP,  QIHMI,  QIH  Management  and SFM LLC may be
deemed the  beneficial  owner of 2,630,625  Shares  (approximately  9.72% of the
total number of Shares outstanding).

                  (ii) Mr. Soros may be deemed the beneficial owner of 3,325,300
Shares (approximately 12.29% of the total number of Shares outstanding). This
number includes (A) 2,630,625 Shares held for the account of QIP and (B) 694,675
Shares held for the account of SFM Domestic Investments.


          (b)     (i) Each of QIP, QIHMI,  QIH Management and SFM LLC (by virtue
of the QIP  Contract)  and Mr. Soros (as a result of his position  with SFM LLC)
may be deemed to have the sole power to direct the voting and disposition of the
2,630,625 Shares held for the account of QIP.


                  (ii) Mr. Soros in his capacity as the sole managing member of
SFM Domestic Investments may be deemed to have the sole power to direct the
voting and disposition of the 694,675 Shares held for the account of SFM
Domestic Investments.
