ITEM 5.02 DEPARTURE OF DIRECTORS OR CERTAIN OFFICERS; ELECTION OF DIRECTORS;
          APPOINTMENT OF CERTAIN OFFICERS; COMPENSATORY ARRANGEMENTS OF CERTAIN
          OFFICERS.

THE FOLLOWING DISCLOSURE IS MADE PURSUANT TO ITEM 5.02(F) OF FORM 8-K:

Footnote 7 to the Summary Compensation Table in our 2008 proxy statement dated
May 22, 2008 stated that Masaaki Tanaka, President and Chief Executive Officer,
might receive a discretionary annual cash payment paid by The Bank of
Tokyo-Mitsubishi UFJ and reimbursed by us under our service agreement with The
Bank of Tokyo-Mitsubishi UFJ. This cash payment would be for the service period
from July 1, 2007 to June 30, 2008. Prior to July 2008, the actual amount of
this cash payment was not calculable, and so the amount of the payment to Mr.
Tanaka was not included in the Summary Compensation Table in reliance on
Instruction 1 to Item 402(c)(2)(iv) of Regulation S-K.

On July 2, 2008, our Executive Compensation & Benefits Committee approved the
reimbursement to The Bank of Tokyo-Mitsubishi UFJ of $211,950 for the annual
discretionary cash payment described above, of which $105,975 was attributable
to service rendered for 2007 compensation and would appear in the "Bonus" column
for 2007.

Also on July 2, 2008, our Executive Compensation & Benefits Committee approved
the reimbursement to The Bank of Tokyo-Mitsubishi UFJ of an additional
discretionary bonus of $77,830 to Mr. Tanaka, of which $38,915 was attributable
to service rendered for 2007 compensation and would appear in the "Bonus" column
for 2007.

Mr. Tanaka's total 2007 compensation, as recalculated to include these bonuses,
is $668,662.
