Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangement of Certain Officers

(e) Compensatory Arrangement of Certain Officers

On December 19, 2008, 3M Company adopted and approved amended and restated plan documents for the 3M Nonqualified Pension Plan I (“Plan I”) and the 3M Nonqualified Pension Plan II (“Plan II”). The effective date of these amended and restated plan documents is January 1, 2009.

The following is a summary of the material terms of Plan I and Plan II (the “Plans”) and is qualified in its entirety by reference to the full terms of the amended and restated plan documents, which are attached hereto as Exhibits 10.1 and 10.2 and incorporated by reference into this Item 5.02.

(1) The purpose of the Plans is to provide additional pension benefits to those of the Company’s U.S. employees whose benefits under 3M’s qualified pension plan are restricted by various tax law limits.

(2) Participation in the Plans is limited to employees of 3M Company and its U.S. subsidiaries who participate in the Company’s qualified pension plan and whose benefits under such plan are limited by reason of various federal tax law limits applicable to such plan.

(3) The additional pension benefits payable by the Plans are generally the amount by which the pension benefits that would be paid by the Company’s qualified pension plan if such benefits were not limited by reason of such federal tax law limits exceed the amount of pension benefits actually payable by such qualified pension plan.

(4) A participant in the Plans who is not entitled to a vested benefit under 3M’s qualified pension plan is not entitled to receive any benefit under the Plans unless and until such participant’s benefits under the qualified pension plan become vested.

(5) Neither Plan I nor Plan II will be funded by the Company, and all amounts payable under the Plans will be paid from the general assets of 3M Company. The rights of each participant under the Plans will be no greater than the rights of a general unsecured creditor of the Company.

(6) All of a participant’s benefits under both Plan I and Plan II are generally payable in the form of a lump sum cash payment following the participant’s separation from service with the Company (subject to a 6-month delay for certain employees as required by section 409A of the Internal Revenue Code of 1986). Certain participants were allowed a one-time opportunity to elect to receive payment of their Plan I and Plan II benefits in the form of a life annuity following their retirement from employment with the Company.

(7) Both Plans may be amended or terminated at any time by the Compensation Committee or the Board of Directors of 3M Company. However, no amendment of the Plans may adversely affect the rights of participants acquired under the terms of the Plans in effect prior to the amendment.
