         3M Company, a corporation duly organized and existing under the laws of
the State of Delaware (hereinafter called the "Company", which term includes any
successor Person under the Indenture), for value received, hereby promises to
pay to Cede & Co., or registered assigns, as principal the Principal Amount on
the Stated Maturity Date and to pay interest thereon, at the Interest Rate shown
above (computed on the basis of a 360-day year of twelve 30-day months),
semi-annually on each Interest Payment Date set forth above from and after the
date of this Security and at Maturity until payment of the principal amount
hereof has been made or duly provided for. Unless this Security is a Security
which has been issued upon transfer of, in exchange for, or in replacement of, a
Predecessor Security, interest on this Security shall accrue from the Original
Issue Date indicated above. If this Security has been issued upon transfer of,
in exchange for, or in replacement of, a Predecessor Security, interest on this
Security shall accrue from the last Interest Payment Date to which interest was
paid on such Predecessor Security or, if no interest was paid on such
Predecessor Security, from the Original Issue Date indicated above. The first
payment of interest on this Security shall be on the first Interest Payment Date
that is at least 15 calendar days after the Original Issue Date. Any premium and
any such installment of interest that is overdue at any time shall also bear
interest (to the extent that the payment of such interest shall be legally
enforceable), at the rate per annum at which the principal then bears interest,
from the date any such overdue amount first becomes due until it is paid or made
available for payment. Notwithstanding the foregoing, interest on any principal,
premium or installment of interest that is overdue shall be payable on demand.

         The interest so payable, and punctually paid or duly provided for, on
any Interest Payment Date will, as provided in the Indenture, be paid to the
Person in whose name this Security (or one or more Predecessor Securities) is
registered at the close of business on the 15th calendar day (whether or not a
Business Day, as such term is defined in Section 3(c) on the reverse hereof)
next preceding such Interest Payment Date (a "Regular Record Date"). Any
interest so payable, but not punctually paid or duly provided for, on any
Interest Payment Date will forthwith cease to be payable to the Holder on such
Regular Record Date and such Defaulted Interest either may be paid to the Person
in whose name this Security (or one or more Predecessor Securities) is
registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest to be fixed by the Trustee, notice whereof shall be
given to the Holder of this Security not less than 10 days prior to such Special
Record Date, or may be paid in any other lawful manner not inconsistent with the
requirements of any securities exchange on which this Security may be listed,
and upon such notice as may be required by such exchange, all as more fully
provided in the Indenture.

CURRENCY OF PAYMENT

         Payment of principal of (and premium, if any) and interest on this
Security will be made in the Specified Currency for such payment, except as
provided in this and the next three paragraphs. The Specified Currency for any
payment shall be the currency specified as such on the face of this Security
unless, at the time of such payment, such currency is not legal tender for the
payment of public and private debts in the country issuing such currency on the
Original Issue Date, in which case the Specified Currency for such payment shall
be such coin or currency as at the time of such payment is legal tender for the
payment of public and private debts in such country, except as provided in the
next sentence. If the euro is specified on the face of this Security as the
Specified Currency for any payment, the Specified Currency for such


                                       3

<PAGE>

payment shall be such coin or currency as at the time of payment is legal tender
for the payment of public and private debts in all EMU Countries (as defined in
Section 3(c) on the reverse hereof), provided that, if on any day there are not
at least two EMU Countries, or if on any day there are at least two EMU
Countries but no coin or currency is legal tender for the payment of public and
private debts in all EMU Countries, then the Specified Currency for such payment
shall be deemed not to be available to the Company on such day.

         Except as provided in the next paragraph, any payment to be made on
this Security in a Specified Currency other than U.S. dollars will be made in
U.S. dollars if the Person entitled to receive such payment transmits a written
request for such payment to be made in U.S. dollars to the Trustee at its
Corporate Trust Office, on or before the tenth day before the payment is to be
made. Such written request may be mailed, hand delivered, telecopied or
delivered in any other manner approved by the Trustee. Any such request made
with respect to any payment on this Security payable to a particular Holder will
remain in effect for all later payments on this Security payable to such Holder,
unless such request is revoked on or before the tenth day before a payment is to
be made, in which case such revocation shall be effective for such and all later
payments. In the case of any payment of interest payable on an Interest Payment
Date, such written request must be made by the Person who is the registered
Holder of this Security on the relevant Regular Record Date.

         The U.S. dollar amount of any payment made pursuant to the preceding
paragraph will be determined by the Exchange Rate Agent based upon the highest
bid quotation received by the Exchange Rate Agent as of 11:00 A.M., New York
City time, on the second Business Day preceding the applicable payment date,
from three (or, if three are not available, then two) recognized foreign
exchange dealers selected by the Exchange Rate Agent in The City of New York, in
each case for the purchase by the quoting dealer, for U.S. dollars and for
settlement on such payment date of an amount of the Specified Currency for such
payment equal to the aggregate amount of such Specified Currency payable on such
payment date to all Holders of Securities of this or any other series who elect
to receive U.S. dollar payments on such payment date, and at which the
applicable dealer commits to execute a contract. If the Exchange Rate Agent
determines that two such bid quotations are not available on such second
Business Day, such payment will be made in the Specified Currency for such
payment. All currency exchange costs associated with any payment in U.S. dollars
on this Security will be borne by the Holder entitled to receive such payment,
by deduction from such payment.

         Notwithstanding the foregoing, if any amount payable on this Security
is payable on any day (including at Maturity) in a Specified Currency other than
U.S. dollars, and if such Specified Currency is not available to the Company on
the two Business Days before such day, due to the imposition of exchange
controls, disruption in a currency market or any other circumstances beyond the
control of the Company, the Company will be entitled to satisfy its obligation
to pay such amount in such Specified Currency by making such payment in U.S.
dollars. The amount of such payment in U.S. dollars shall be determined by the
Exchange Rate Agent on the basis of the noon buying rate for cable transfers in
The City of New York for such Specified Currency (the "Exchange Rate") as of the
latest day before the day on which such payment is to be made. Any payment made
under such circumstances in U.S. dollars where the required payment is in other
than U.S. dollars will not constitute an Event of Default under the Indenture or
this Security.

MANNER OF PAYMENT - U.S. DOLLARS

         Except as provided in the next paragraph, payment of any amount payable
on this Security in U.S. dollars will be made at the office or agency of the
Company maintained for that purpose in The City of New York (or at any other
office or agency maintained by the Company for that purpose), against surrender
of this Security in the case of any payment due at the Maturity of the principal
hereof (other than any payment of interest that first becomes due on an Interest
Payment Date); provided, however, that, at the option of the Company and subject
to the next paragraph, payment of interest may be made by check mailed to the
address of the Person entitled thereto as such address shall appear in the
Security Register.

         Payment of any amount payable on this Security in U.S. dollars will be
made by wire transfer of immediately available funds to an account maintained by
the payee with a bank located in The City of New York, if (i) the principal of
this Security is at least $1,000,000 and (ii) the Holder entitled to receive
such payment transmits a written request for such payment to be made in such
manner to the Paying Agent at its Corporate Trust Office, Attention: Citibank
Agency & Trust Services, on or before the tenth day before the day on which such
payment is to be made; provided that, in the case of any such payment due at the
Maturity of the principal hereof (other than any payment of interest that first
becomes due on an Interest Payment Date), this Security must be surrendered at
the office or agency of the Company maintained for that purpose in The City of
New York (or at any other office or agency maintained by the Company for that
purpose) in time for the Paying Agent to make such payment in such funds in
accordance with its normal procedures. Any such request made with respect to any
payment on this Security payable to a particular Holder will remain in effect
for all later payments on this Security payable to such Holder, unless such
request is revoked on or before the tenth day before a payment is to be made, in
which case such revocation shall be effective for such and all later payments.
In the case of any payment of interest payable on an Interest Payment Date, such
written request must be made by the Person who is the registered Holder of this
Security on the relevant Regular Record Date. The Company will pay any
administrative costs imposed by banks in connection with making payments by wire
transfer with respect to this Security, but any tax, assessment or other
governmental charge imposed upon any payment will be borne by the Holder of this
Security and may be deducted from the payment by the Company or the Paying
Agent.

MANNER OF PAYMENT - OTHER SPECIFIED CURRENCIES

         Payment of any amount payable on this Security in a Specified Currency
other than U.S. dollars will be made by wire transfer of immediately available
funds to such account as is maintained in such Specified Currency at a bank or
other financial institution acceptable to the Company and the Trustee and as
shall have been designated at least ten days prior to the applicable payment
date by the Person entitled to receive such payment; provided that, in the case
of any such payment due at the Maturity of the principal hereof (other than any
payment of interest that first becomes due on an Interest Payment Date), this
Security must be surrendered at the office or agency of the Company maintained
for that purpose in The City of New York (or at any other office or agency
maintained by the Company for that purpose) in time for the Paying Agent to make
such payment in such funds in accordance with its normal procedures. Such
account designation shall be made by transmitting the appropriate information to
the Paying Agent at its Corporate Trust Office, Attention: Citibank Agency &
Trust Services, by mail, hand


                                       5
<PAGE>

delivery, telecopier or in any other manner approved by the Trustee. Unless
revoked, any such account designation made with respect to this Security by the
Holder hereof will remain in effect with respect to any further payments with
respect to this Security payable to such Holder. If a payment in a Specified
Currency other than U.S. dollars with respect to this Security cannot be made by
wire transfer because the required account designation has not been received by
the Paying Agent on or before the requisite date or for any other reason, the
Company will cause a notice to be given to the Holder of this Security at its
registered address requesting an account designation pursuant to which such wire
transfer can be made and such payment will be made within five Business Days
after the Paying Agent's receipt of such a designation meeting the requirements
specified above, with the same force and effect as if made on the due date. The
Company will pay any administrative costs imposed by banks in connection with
making payments by wire transfer with respect to this Security, but any tax,
assessment or other governmental charge imposed upon any payment will be borne
by the Holder of this Security and may be deducted from the payment by the
Company or the Paying Agent.

MANNER OF PAYMENT - GLOBAL SECURITIES

         Notwithstanding any provision of this security or the Indenture, if
this Security is a Global Security, the Company may make any and all payments of
principal, premium and interest on this Security pursuant to the applicable
policies of the Depositary for this Security as permitted in the Indenture.

PAYMENTS DUE ON A BUSINESS DAY

         Unless otherwise specified on the face of this Security, the following
sentence shall apply to this Security. Notwithstanding any provision of this
Security or the Indenture, if any amount of principal, premium or interest would
otherwise be due on this Security on a day (the "Specified Day") that is not a
Business Day, such amount may be paid or made available for payment on the next
succeeding Business Day with the same force and effect as if such amount were
paid on the Specified Day. The provisions of this paragraph shall apply to this
Security in lieu of the provisions of Section 113 of the Indenture.

         Reference is hereby made to the further provisions of this Security set
forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

the Trustee by manual signature, this Security shall not be entitled to any
benefit under the Indenture or be valid or obligatory for any purpose.

                              (Reverse of Security)

         1.       SECURITIES AND INDENTURE

         This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities") issued and to be issued in one or more
series under an Indenture, dated as of November 17, 2000 (herein called the
"Indenture", which term shall have the meaning assigned to it in such
instrument), between the Company and Citibank, N.A., as Trustee (herein called
the "Trustee", which term includes any successor trustee under the Indenture),
and reference is hereby made to the Indenture for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Company,
the Trustee and the Holders of the Securities and of the terms upon which the
Securities are, and are to be, authenticated and delivered.

         2.       SERIES AND DENOMINATIONS

         This Security is one of the series designated on the face hereof,
limited to an aggregate principal amount not to exceed $1,500,000,000 (or the
equivalent thereof in any other currency or currencies or currency units), which
amount may be increased at the option of the Company if in the future it
determines that it may wish to sell additional Securities of this series.
References herein to "this series" mean the series of securities designated on
the face hereof.

         The Securities of this series are issuable only in registered form
without coupons in "Authorized Denominations", which term shall have the
following meaning. For each Security of this series having a principal amount
payable in U.S. dollars, the Authorized Denominations shall be $1,000 and
integral multiples thereof. For each Security of this series having a principal
amount payable in a Specified Currency other than U.S. dollars, the Authorized
Denominations shall be the amount of such Specified Currency equivalent, at the
Exchange Rate on the first Business Day next preceding the date on which the
Company accepts the offer to purchase such Security, to $1,000 and any integral
multiple thereof.

         3.       INTEREST RATE

         (a) CALCULATION OF INTEREST. Payments of interest hereon with respect
to any Interest Payment Date or at the Maturity of the principal hereof will
include interest accrued to but excluding such Interest Payment Date or the date
of such Maturity, as the case may be.

         All percentages resulting from any calculation with respect to this
Security will be rounded upward or downward, as appropriate, to the next higher
or lower one hundred-thousandth of a percentage point (e.g., 9.876541% (or
..09876541) being rounded down to 9.87654% (or .0987654) and 9.876545% (or
..09876545) being rounded up to 9.87655% (or .0987655) ). All amounts used in or
resulting from any calculation with respect to this Security will be rounded
upward or downward, as appropriate, to the nearest cent, in the case of U.S.
dollars, or to the nearest corresponding hundredth of a unit, in the case of a
currency other than U.S. dollars, with one-half cent or one-half of a
corresponding hundredth of a unit or more being rounded upward.



                                       8
<PAGE>

         (b) EXCHANGE RATE AGENT. The Company has initially appointed the
institution named on the face of this Security as Exchange Rate Agent, to act as
such agent with respect to this Security, but the Company may, in its sole
discretion, appoint any other institution (including any Affiliate of the
Company) to serve as such agent from time to time. The Company will give the
Trustee prompt written notice of any change in any such appointment. Insofar as
this Security provides for any such agent to obtain rates, quotes or other data
from a bank, dealer or other institution for use in making any determination
hereunder, such agent may do so from any institution or institutions of the kind
contemplated hereby notwithstanding that any one or more of such institutions
are any such agent, Affiliates of any such agent or Affiliates of the Company.

         All determinations made by the Exchange Rate Agent may be made by such
agent in its sole discretion and, absent manifest error, shall be conclusive for
all purposes and binding on the Holder of this Security and the Company. The
Exchange Rate Agent shall not have any liability therefor.

         (c) DEFINITIONS OF TERMS. As used in this Security, the following terms
have the meanings set forth below:

                  (ii) if the Specified Currency for payment of principal of or
         interest on this Security is other than U.S. dollars or euros, is also
         a day on which banking institutions in the principal financial center
         of the country issuing such Specified Currency are not authorized or

                  (iv) solely with respect to any payment or other action to be
         made or taken at any Place of Payment outside The City of New York, is

         4.       REDEMPTION AT THE COMPANY'S OPTION

         Unless a Redemption Commencement Date is specified on the face hereof,
this Security shall not be redeemable at the option of the Company before the
Stated Maturity Date. If a Redemption Commencement Date is so specified, and
unless otherwise specified on the face hereof, this Security is subject to
redemption upon not less than 30 days' nor more than 60 days' notice at any time
and from time to time on or after the Redemption Commencement Date, in each case
as a whole or in part, at the election of the Company and at the applicable
Redemption Price specified on the face hereof (expressed as a percentage of the
principal amount of this Security to be redeemed), together with accrued
interest to the Redemption Date, but interest installments due on or prior to
such Redemption Date will be payable to the Holder of this Security, or one or
more Predecessor Securities, of record at the close of business on the relevant
Regular Record Date, all as provided in the Indenture.

         5.       REPAYMENT AT THE HOLDER'S OPTION

         Except as otherwise may be provided on the face hereof, if one or more
Repayment Dates are specified on the face hereof, this Security will be
repayable in whole or in part in an amount equal to any Authorized Denomination
(provided that the remaining principal amount of any Security surrendered for
partial repayment shall at least equal an Authorized Denomination), on any such
Repayment Date, in each case at the option of the Holder and at the applicable
Repayment Price specified on the face hereof (expressed as a percentage of the
principal amount to be repaid), together with accrued interest to the applicable
Repayment Date (but interest installments due on or prior to such Repayment Date
will be payable to the Holder of this Security, or one or more Predecessor
Securities, of record at the close of business on the relevant Regular Record
Date as provided in the Indenture). If this Security provides for more than one
Repayment Date, and the Holder exercises its option to elect repayment, the
Holder shall be deemed to have elected repayment on the earliest repayment date
after all conditions to


                                       10
<PAGE>

such exercise have been satisfied, and references herein to the applicable
Repayment Date shall mean such earliest Repayment Date.

         In order for the exercise of such option to be effective and this
