                    YOUR VOTE IS VERY IMPORTANT

Dear Stockholder:

      We are writing to remind you that we still have not
received your proxy card for the upcoming July 31 Special
Meeting.

      At the Special Meeting, stockholders will consider three
proposals related to our pending merger with U. S. Bancorp.
Approval of the merger requires an affirmative vote by holders of
50% of the Company's outstanding shares and a related proposal to
amend our certificate of incorporation to increase the maximum
size of our Board of Directors requires a supermajority vote by
holders of 80% of the Company's outstanding shares. AS A RESULT,
NOT VOTING HAS THE SAME EFFECT AS VOTING AGAINST THESE PROPOSALS.

        THE SPECIAL MEETING IS JULY 31. PLEASE VOTE TODAY.

      By the time you receive this letter, the Special Meeting
will be less than two weeks away. Please take a moment to sign
and date the enclosed proxy card and return it in the
postage-paid envelope provided. Your Board of Directors
unanimously recommends that you vote FOR all three proposals.

      YOUR VOTE IS EXTREMELY IMPORTANT -- NO MATTER HOW MANY
SHARES YOU OWN. VOTING PROMPTLY WILL ALSO SAVE OUR COMPANY
ADDITIONAL SOLICITATION EXPENSES.

      If you have any questions about voting your shares, please
contact our proxy solicitation firm, MacKenzie Partners, Inc., at
(800) 322-2885. We appreciate your prompt cooperation and support
of First Bank System.

                                    Sincerely,

                                    /s/ Lee R. Mitau

                         IMPORTANT REQUEST

Dear Stockholder:

      We have instructed our transfer agent to send this letter
and a duplicate proxy card to all stockholders who voted against
Proposal 2 for our July 31 Special Meeting. Proposal 2 relates to
the expansion of the Board of Directors in connection with our
pending merger with U. S. Bancorp.

      The purpose of Proposal 2 is to enable the Board to
initially accommodate all 15 current directors of First Bank
System and all 11 current directors of U. S. Bancorp after the
merger. However, it is intended that the size of the Board will
be substantially reduced at the next annual meeting. If Proposal
2 is not approved, it will cause us to require some members of
the Board to resign in order to implement the merger and we do
not believe this would be in the best interests of the Company
and its stockholders.

      WE HOPE THAT YOU WILL RECONSIDER YOUR DECISION AND VOTE FOR
PROPOSAL 2 ON THE ENCLOSED PROXY CARD AND RETURN IT IN THE
POSTAGE-PAID ENVELOPE PROVIDED.

      First Bank System has a confidential voting policy.
Therefore, we have asked our proxy solicitor, MacKenzie Partners,
Inc., to contact stockholders who have voted against Proposal 2
to discuss it with them without disclosing their identity to the
Company. Of course, we at First Bank System would welcome the
opportunity to speak directly with you, if you so desire.

      If you have any questions, please call MacKenzie Partners
at (800) 322-2885 or our Shareholder Relations Department at
(800) 947-9820. We appreciate your prompt cooperation and support
of First Bank System.

                                    Sincerely,

                                    /s/ Lee R. Mitau
