Explanation of Responses:

1. This Form is being filed to report the exercise of a 3M stock option for a total of 50,500 shares by means of a stock swap. A stock swap is a method of exercising a stock option in which the option holder attests to the ownership of enough shares of stock already owned by the option holder to cover the exercise price of the option being exercised. As a result of this stock swap, the reporting person acquired ownership of an additional 6,823 shares of 3M common stock. As a result of this transaction, 9,656 shares were sold to pay withholding taxes to the respective government agencies.

2. Includes shares acquired during the fiscal year pursuant to the 3M Voluntary Investment Plan.
