                         3M WINS MAJOR INSURANCE RULING

         St. Paul, MN - Aug. 21, 2003 - The Minnesota Supreme Court ruled in
favor of 3M today in litigation with its insurers over insurance coverage for
breast implant claims. The court's ruling confirms insurance coverage owed to 3M
by 29 insurers remaining in the case and holds that these insurers are liable up
to the limits of their respective policies. This ruling

essentially concludes the eight-year litigation between 3M and these insurers.
Subsequent proceedings to effectuate today's ruling are expected.

         "We're very pleased by the court's decision today requiring insurers to
provide the insurance benefits purchased by 3M," said Richard Ziegler, senior
vice president, Legal Affairs and General Counsel. "This ruling is good not only
for 3M, but for all policyholders because it reaffirms insurers' responsibility
to meet their coverage obligations."

         3M expects to collect approximately $250 million from these insurers as
a result of this decision. This event will not impact 3M's earnings as the
amount received will offset a portion of a previously recorded receivable.

This news release contains forward-looking statements that reflect current views
and estimates of 3M's management of future economic circumstances, industry
conditions, company performance and financial results. The statements are based
on many assumptions and factors, such as legal proceedings, as described in the
Company's Annual Report on Form 10-K for the year ended December 31, 2002, and
in its subsequent periodic reports on Forms 10-Q. Any changes in such
assumptions or factors could produce significantly different results.
