This is an amendment to the pricing supplement, subject to completion, dated January 26, 2006 (the “preliminary pricing supplement”), to the prospectus supplement dated June 1, 2005 and the prospectus dated May 3, 2005. This amendment should be read together with the preliminary pricing supplement, the prospectus supplement and the prospectus.

On page PS-5 of the preliminary pricing supplement, in the section entitled “Interest Accrual—Hypothetical Examples”, the dollar amounts listed in the final column entitled “Hypothetical Quarterly Interest Payment per $1,000” are incorrect. A revised table, including the correct dollar amounts for the “Hypothetical Quarterly Interest Payment per $1,000” column, is set forth below:

Total Accrual Days During Interest Calculation Period	Hypothetical Quarterly Interest Rate Accrued per Annum	Hypothetical Quarterly Interest Payment per $1,000
0 10 20 30 40 50 60 70 80 90	0.00% 0.67% 1.33% 2.00% 2.67% 3.33% 4.00% 4.67% 5.33% 6.00%	$   0.00 $   1.67 $   3.33 $   5.00 $   6.67 $   8.33 $ 10.00 $ 11.67 $ 13.33 $ 15.00
