or postponements thereof.

     I instruct Putnam Fiduciary Trust Company, as trustee of the BancWest
Corporation Future Plan and the BancWest Corporation Defined Contribution Plan,
to vote all shares of BancWest Corporation Common Stock allocated to my accounts
in those plans (1) as set forth on the reverse side of this card as to Proposal

business which may properly come before the meeting or any adjournments or
postponements of the special meeting. However, these instructions do not
authorize the trustee to vote such shares on any proposal to adjourn or postpone

the adoption of the merger agreement.

     If no instruction card is submitted to the trustee, such shares will not
be voted.
