As representatives of the several Purchasers

identified in Schedule I hereto

Dear Ladies and Gentlemen:

Reference is made to the Second Amended and Restated Distribution Agreement, dated May 19, 2016 (the “Distribution Agreement”), between 3M Company (the “Company”) on the one hand and the agents from time to time a party thereto (the “Agents”) on the other relating to the issuance and sale by the Company from time to time of its medium-term notes, Series F (the “MTN Program”).  The Company proposes to issue and sell to Barclays Bank PLC (“Barclays”), Credit Suisse Securities (Europe) Limited (“Credit Suisse”) Deutsche Bank AG, London Branch (“Deutsche Bank”) and each of the entities identified in Schedule I hereto (the “Purchasers”) for whom Barclays, Credit Suisse and Deutsche Bank are acting as representatives, the securities specified in Schedule I hereto (the “Purchased Securities”).  The Company hereby appoints each of the Purchasers as an Agent under the MTN Program but only in respect of the Purchased Securities and each of the Purchasers hereby accepts such appointment.  For the purposes of the sale and offering of the Purchased Securities as contemplated hereby, each of the Purchasers named herein agrees that it shall be bound by the obligations of Agents set forth in, and shall be entitled to the benefits of such Agents pursuant to, the provisions of the Distribution Agreement

and each of the provisions of the Distribution Agreement (excluding, for the avoidance of doubt, the Administrative Procedure (as defined therein) and any provisions related to the solicitation by the Agents, as agents of the Company, of offers to purchase Securities) is incorporated herein by reference in its entirety, and shall be deemed to be part of this Terms Agreement to the same extent as if such provisions had been set forth in full herein.  Nothing contained herein or in the Distribution Agreement shall make any party hereto an agent of the Company or make such party subject to the provisions therein relating to the solicitation of offers to purchase Securities from the Company, solely by virtue of its execution of this Terms Agreement.  Each of the representations and warranties set forth therein shall be deemed to have been made at and as of the date of this Terms Agreement to the Purchasers, except that each representation and warranty in Section 1 of the Distribution Agreement which makes reference to the Prospectus shall be deemed to be a representation and warranty as of the date of the Distribution Agreement in relation to the Prospectus (as therein defined), and also a representation and a warranty as of the date of this Terms Agreement in relation to the Prospectus as amended and supplemented to relate to the Purchased Securities.

A supplement to the Prospectus relating to the Purchased Securities, substantially in the form attached as Schedule IV hereto (the “Pricing Supplement”), will be filed with the Commission within the time period specified in Rule 424(b) under the Securities Act of 1933, as amended. The Purchased Securities will be issued in book-entry form through a common depositary for Clearstream Banking, S.A. (“Clearstream”), and Euroclear Bank S.A./N.V., as operator of the Euroclear system (“Euroclear”), and will be issued in denominations of €100,000 and integral multiples of €1,000 in excess thereof, all as more fully described in the Pricing Supplement.

1.                                      Subject to the terms and conditions set forth herein and in the Distribution Agreement incorporated herein by reference:

(a)                                 the Company agrees to issue and sell to the Purchasers identified in Schedule I hereto, and such Purchasers severally agree to purchase from the Company, the Purchased Securities, at the time and place, in the respective principal amounts and at the respective purchase prices set forth in Schedule I hereto;

(b)                                 the Company represents and warrants that the form of the Purchased Securities shall comply with the requirements of the rules of the New York Stock Exchange (the “NYSE”);

(c)                                  the Company represents and warrants that the paying and calculation agency agreement (the “Paying and Calculation Agency Agreement”) to be dated as of May 31, 2016 between the Company, The Bank of New York Mellon, London Branch, as paying and calculation agent, and The Bank of New York Mellon Trust Company, N.A., as trustee, has been duly authorized and, as of the closing date of the offering of the Purchased Securities, will be duly executed and delivered and constitute a valid and legally binding instrument, enforceable in accordance with its terms, subject, as to enforcement, to bankruptcy, insolvency, reorganization and other laws of general applicability relating to or affecting creditors’ rights and to general equity principles; and

2

the Paying and Calculation Agency Agreement conforms to the descriptions thereof in the Prospectus and the Disclosure Package;

(d)                              the Company will use its reasonable best efforts to cause the Purchased Securities to be listed for trading on the NYSE as of the date of the issuance of the Purchased Securities, or as promptly as practicable thereafter, and, upon such listing, the Company will use its reasonable best efforts to maintain such listing and satisfy the requirements for such continued listing;

(e)                                  the Company hereby authorizes Deutsche Bank in its role as stabilizing manager (the “Stabilizing Manager”) to make adequate public disclosure regarding stabilization of the information required in relation to such stabilization by Commission Regulation (EC) 2273/2003 of the Commission of the European Communities. The Stabilizing Manager for its own account may, to the extent permitted by applicable laws and directives, over-allot and effect transactions with a view to supporting the market price of the Purchased Securities at a level higher than that which might otherwise prevail, but in doing so the Stabilizing Manager shall act as principal and not as agent of the Company and any loss resulting from overallotment and stabilization shall be borne, and any profit arising therefrom shall be beneficially retained, by the Stabilizing Manager. However, there is no assurance that the Stabilizing Manager (or persons acting on behalf of the Stabilizing Manager) will undertake any stabilization action. Nothing contained in this paragraph shall be construed so as to require the Company to issue in excess of the aggregate principal amount of Purchased Securities specified in Schedule I hereto.  Such stabilization, if commenced, may be discontinued at any time and shall be conducted by the Stabilizing Manager in accordance with all applicable laws and directives;

(g)                                  each Purchaser hereby represents and agrees that it and each of its affiliates, if any, through which it may offer and sell the Purchased Securities: (i) has complied and will comply with all applicable provisions of the United Kingdom’s Financial Services and Markets Act of 2000, as amended (the “FSMA”) with respect to anything done by it in relation to any Purchased Securities in, from or otherwise involving the United Kingdom; and (ii) has only communicated or caused to be communicated and will only communicate or cause to be communicated an invitation or inducement to engage in investment activity (within the meaning of Section 21 of the FSMA) received by it in connection with the issue or sale of any Purchased Securities in circumstances in which Section 21(1) of the FSMA does not apply to the Company; and

(h)                                 the Company agrees to pay any stamp duty or other issue, transaction, value added or similar tax, fund or duty (including court fees) payable in the United States of America, Belgium, Luxembourg or the United Kingdom in connection with the issue and distribution of the Purchased Securities or the enforcement or delivery of this Terms Agreement.

2.                                      If one or more of the Purchasers shall fail at the Time of Delivery to purchase the Purchased Securities (such Purchased Securities, including any Purchased Securities which any

3

such Purchaser is no longer obligated to purchase in accordance with the exercise of Bail-in Powers described in Section 6 hereof, the “Defaulted Securities”), then the nondefaulting Purchasers shall have the right, within 24 hours thereafter, to make arrangements for one of them or one or more other Purchasers to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; provided, however, that if such arrangements shall not have been completed within such 24-hour period, then:

(a)                                 if the aggregate principal amount of Defaulted Securities does not exceed 10% of the aggregate principal amount of Purchased Securities, the nondefaulting Purchasers shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective initial obligations under this Terms Agreement bear to the obligations of all nondefaulting Purchasers under this Terms Agreement; or

(b)                                 if the aggregate principal amount of Defaulted Securities exceeds 10% of the aggregate principal amount of Purchased Securities, this Terms Agreement shall terminate without liability on the part of any nondefaulting Purchasers.

No action taken pursuant to this Section 2 shall relieve any defaulting Purchaser from liability in respect of its default.  In the event of any such default which does not result in a termination of this Terms Agreement, either the nondefaulting Purchasers or the Company shall have the right to postpone the Time of Delivery for a period not exceeding seven days in order to effect any required changes in the Registration Statement or the Prospectus or in any other documents or arrangements.

3.                                      The execution of this Terms Agreement by all parties will constitute the Purchaser’s acceptance of the ICMA Agreement Among Managers Version 1/New York Schedule subject to any amendment notified to the Purchasers in writing at any time prior to the execution of this Terms Agreement. References to the “Managers” shall be deemed to refer to the Purchasers, references to the “Lead Manager” shall be deemed to refer to Barclays, Credit Suisse and Deutsche Bank and references to “Settlement Lead Manager” shall be deemed to refer to Deutsche Bank. As applicable to the Purchasers, Clause 3 of the ICMA Agreement Among Managers Version 1/New York Schedule shall be deemed to be deleted in its entirety and replaced with Section 2 of this Terms Agreement.

4.                                      For purposes of this Terms Agreement and the transactions contemplated herein:

(i)                                     Section 5 of the Distribution Agreement is hereby amended by adding new clause “(x) the fees and expenses incurred in connection with the listing of the Securities on the New York Stock Exchange; and” (with deletion of “and” at the end of clause (ix) and the renumbering of the existing clause (x) to (xi)).
