EXHIBIT 10.b FIRST BANK SYSTEM, INC. EMPLOYEE STOCK PURCHASE PLAN 1984 (As Amended and Restated February 15, 1989 and As Amended and Restated April 24, 1991 and reflecting further amendments through April 17, 1996) ARTICLE I. INTRODUCTION Section 1.01 Purpose. The purpose of this 1984 Employee Stock Purchase Plan (amended and restated as of February 15, 1989) (the "Plan") is to provide employees of First Bank System, Inc., a Delaware corporation (the "Company"), and certain related corporations with an opportunity to share in the ownership of the Company by providing them with a convenient means for regular and systematic purchases of the Company's Common Stock, par value $1.25 per share, and, thus, to develop a stronger incentive to work for the continued success of the Company. The Plan shall constitute an amendment and restatement of the Company's existing 1984 Employee Stock Purchase Plan (as amended January 31, 1987) (the "Former Plan") and as such shall supersede and replace the Former Plan. No additional offers to purchase shares of the Company's Common Stock or any other rights or benefits shall be provided or granted under the Former Plan; provided, however, that the Former Plan shall deem to be outstanding to the extent necessary solely for the purpose of determining the terms and conditions of any such purchase offer or other rights previously granted under the Former Plan. Section 1.02 Rules of Interpretation. It is intended that the Plan be an "employee stock purchase plan"as defined in Section 423(b) of the Internal Revenue Code of 1986, as amended (the "Code"), and Treasury Regulations promulgated thereunder, if approved by the Company's shareholders. Accordingly, the Plan will be interpreted and administered in a manner consistent therewith if so approved.

If the purchases for all Participants would otherwise cause the aggregate number of shares of Stock to be sold under the Plan to exceed the number specified in Section 10.03, however, each Participant shall be allocated a pro rata portion of the Stock to be sold. Section 4.02 Purchase Price. The purchase price for any Purchase Period shall be that price as announced by the Committee prior to the first business day of that Purchase Period, which price may, in the discretion of the Committee, be a price which is not fixed or determinable as of the first business day of that Purchase Period; provided, however, that in no event shall the purchase price for any Purchase Period be less than (a) 85% of the Fair Market Value of the Stock on the first business day of that Purchase Period or (b) 85% of the Fair Market Value of the Stock on the last business day of that Purchase Period, in each case rounded up to the next higher full cent, whichever is lower. ARTICLE V. EXERCISE OF RIGHT Section 5.01 Purchase of Stock. On the last business day of a Purchase Period, the entire credit balance in each Participant's Stock Purchase Account will be used to purchase the largest number of whole shares of Stock purchasable with such amount (subject to the limitations of Section 4.01), unless the Participant has filed with the Company, in advance of that date and subject to such terms and conditions as the Committee in its sole discretion may impose, a form provided by the Company (which elects to receive the entire credit balance in cash). Section 5.02 Cash Distributions. Any amount remaining in a Participant's Stock Purchase Account after the last business day of a Purchase Period will be paid to the Participant in cash within 30 days after the end of that Purchase Period. Section 5.03 Notice of Acceleration Date. The Company shall use its best efforts to notify each Participant in writing at least ten days prior to any Acceleration Date that the then current Purchase Period will end on such Acceleration Date. ARTICLE VI. WITHDRAWAL FROM PLAN Section 6.01 Voluntary Withdrawal. A Participant may, in accordance with such terms and conditions as the Committee in its sole discretion may impose, withdraw from the Plan and cease making payroll deductions by filing with the Company a form provided for this purpose. In such event, the entire credit balance in the Participant's Stock Purchase Account will be paid to the Participant in cash within 30 days. A Participant who withdraws from the Plan will not be eligible to reenter the Plan until the beginning of the next Purchase Period. Section 6.02 Death. Subject to such terms and conditions as the Committee in its sole discretion may impose, upon the death of a Participant, no further amounts shall be credited to the Participant's Stock Purchase Account. Thereafter, on the last business day of the Purchase Period during which such Participant's death occurred and in accordance with Section 5.01, the entire credit balance in such Participant's Stock Purchase Account will be used to purchase Stock, unless Participant's estate has filed with the Company, in advance of that day and subject to such terms and conditions as the Committee in it sole discretion may impose, a form provided by the Company which elects to have the entire credit balance in such Participant's Stock Purchase Account will be used to purchase Stock, unless Participant's estate has filed with the Company, in advance of that day and subject to such terms and conditions as the Committee in its sole discretion may impose, a form provided by the Company which elects to have the entire credit balance in such participant's Stock Account distributed in cash, in accordance with Section 5.02 or at such earlier time as the Committee in its sole discretion may decide. Each Participant, however, may designate one or more beneficiaries who, upon death, are to receive the stock or the amount that otherwise would have been distributed or paid to the Participant's estate and may change or revoke any such designation from time to time. No such designation, change or revocation will be effective unless made by the Participant in writing and filed with the Company during the Participant's lifetime. Unless the Participant has otherwise specified in the beneficiary designation, the beneficiary or beneficiaries so designated will become fixed as of death so that, if a beneficiary survives the Participant but dies before the receipt of the payment due such beneficiary, the payment will be made to such beneficiary's estate. Section 6.03 Termination of Employment. Subject to such terms and conditions as the Committee in its sole discretion may impose, upon a Participant's normal or early retirement with the consent of the Company under any pension or retirement plan of the Company or Participating Affiliate, no further amounts shall be credited to the Participant's Stock Purchase Account. Thereafter, on the last business day of the Purchase Period during which such Participant's approved retirement occurred and in accordance with Section 5.01, the entire credit balance in such Participant's Stock Purchase Account will be used to purchase Stock, unless such Participant has filed with the Company, in advance of that day and subject to such terms and conditions as the Committee in its sole discretion may impose, a form provided by the Company which elects to receive the entire credit balance in such Participant's Stock Purchase Account in cash, in accordance with Section 5.02; provided, however, that such Participant shall have no right to purchase Stock in the event that the last day of such a Purchase Period occurs more than three (3) months following the termination of such Participant's employment with the Company by reason of such an approved retirement. In the event of any other termination of employment (other than death) with the Company or a Participatory Affiliate by a Participant, participation in the Plan will cease on the date the Participant ceases to be a Permanent Full-Time Employee for any reason. In such event, the entire credit balance in such Participant's Stock Purchase Account will be paid to the Participant in cash within 30 days. For purposes of this Section, a transfer of employment to any Affiliate, or a leave of absence which has been approved by the Committee, will not be deemed a termination of employment as a Permanent Full-Time Employee. ARTICLE VII. NONTRANSFERABILITY Section 7.01 Nontransferable Right to Purchase. The right to purchase Stock hereunder may not be assigned, transferred, pledged or hypothecated (whether by operation of law or otherwise), except as provided in Section 6.02, and will not be subject to execution, attachment or similar process. Any attempted assignment, transfer, pledge, hypothecation or other disposition or levy of attachment or similar process upon the right to purchase will be null and void and without effect. Section 7.02 Nontransferable Account. Except as provided in Section 6.02, the amounts credited to a Stock Purchase Account may not be assigned, transferred, pledged or hypothecated in any way, and any attempted assignment, transfer, pledge, hypothecation or other disposition of such amount will be null and void and without effect. ARTICLE VIII. STOCK CERTIFICATES Section 8.01 Delivery. Promptly after the last day of each Purchase Period and subject to such terms and conditions as the Committee in its sole discretion may impose, the Company will cause to be delivered to or for the benefit of the Participant a certificate representing the Stock purchased on the last business day of such Purchase Period. Section 8.02 Securities Laws. The Company shall not be required to issue or deliver any certificate representing Stock prior to registration under the Securities Act of 1933, as amended, or registration or qualification under any state law if such registration is required. The Company will use its best efforts to accomplish such registration (if and to the extent required) not later than a reasonable time following the Purchase Period, and delivery of certificates may be deferred until such registration is accomplished. Section 8.03 Completion of Purchase. A Participant will have no interest in the Stock purchased until a certificate representing the same is issued to or for the benefit of the Participant. Section 8.04 Form of Ownership.

The Committee shall have full and complete authority to determine whether all or any part of the Stock acquired pursuant to the Plan shall be subject to restrictions on the transferability thereof or any other restrictions affecting in any manner a Participant's rights with respect thereto but any such restrictions shall be contained in the form by which a Participant elects to participate in the Plan pursuant to Section 2.02. Decisions of the Committee will be final and binding on all parties who have an interest in the Plan. Section 10.03 Stock to be Sold.
