FOOTNOTES TO COMMON STOCK AND TOTAL STOCK-BASED HOLDINGS TABLE

(1) This column lists beneficial ownership of 3M common stock as calculated under SEC rules, including restricted stock held by certain of the Executive Officers over which they have sole voting power but no investment power. The restricted stock generally vests over a three- to five-year period if the executive remains continuously employed by the Company and is subject to forfeiture under certain circumstances. Unless otherwise noted, voting power and investment power in the shares are exercisable solely by the named person, and none of the shares are pledged as security by the named person. In accordance with SEC rules, this column also includes shares that may be acquired pursuant to stock options that are or will be exercisable within 60 days of February 28, 2011 as follows: Mr. Buckley (898,608), Mr. Campbell (457,110), Mr. Thulin (380,772), Mr. Shin (258,962), Mr. Kelly (164,834), and Mr. Morrison (92,632). Mr. Morrison’s options were granted during his service as interim CEO from June 30 to December 6, 2005.

(2) This column reflects restricted stock units that generally vest over a three- to five-year period, assuming continued employment until each vesting date (or until the individual retires from the Company, in some cases). This column also includes the following shares of the Company’s common stock which the Named Executive Officer or other Executive Officers are entitled to receive following their retirement from the Company as a result of their election to defer the payout of their 2008 performance share awards under the 3M Performance Unit Plan: Mr. Buckley (27,063.1), and All Directors and Executive Officers as a Group (30,211.796). The Executive Officers do not have voting power with respect to the shares listed in this column.

(5) Of this total number of shares, beneficial ownership of 4,992.271 shares earned by Mr. Buckley as a result of his 2008 performance share award under the 3M Performance Unit Plan has been assigned to his former spouse pursuant to their marital dissolution agreement.

(6) Of this total number of shares, 1,277 shares credited to Mr. Campbell’s Company stock account in the Company’s 401(k) plan have been assigned to his former spouse in connection with the dissolution of their marriage.
