3M Company

Management’s Report on Internal Control over Financial Reporting Management is responsible for establishing and maintaining an adequate system of internal control over financial reporting. Management conducted an assessment of the Company’s internal control over financial reporting based on the framework established by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework. Based on the assessment, management concluded that, as of December 31, 2008, the Company’s internal control over financial reporting is effective. Management’s assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2008 excluded Aearo, which was acquired by the Company in April 2008 in a purchase business combination. Aearo is a wholly-owned subsidiary of the Company whose total assets and total net sales represented less than 10% of consolidated total assets and less than 2% of consolidated net sales, respectively, of the Company as of and for the year ended December 31, 2008. Companies are allowed to exclude acquisitions from their assessment of internal control over financial reporting during the first year of an acquisition while integrating the acquired company under guidelines established by the Securities and Exchange Commission. The Company’s internal control over financial reporting as of December 31, 2008 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which is included herein, which expresses an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2008. 3M Company
