EXHIBIT 10

This EMPLOYMENT AGREEMENT (the "Agreement"), dated as of November 19, 2002, is
entered into between 3M Company, a corporation incorporated under the laws of
Delaware, with its corporate headquarters in St. Paul, Minnesota (the
"Company") and Richard F. Ziegler ("Executive").

	WHEREAS, the Company desires to employ Executive to serve as its Senior
Vice President, Legal Affairs and General Counsel upon the terms and
conditions set forth herein, and Executive wishes to accept employment with
the Company upon such terms and conditions;

	NOW, THEREFORE, in consideration of the premises and the mutual
agreements contained herein, the Company and Executive hereby agree as
follows:

1.	TERM OF AGREEMENT.
(a) Employment Period.  Subject to the termination provisions of this
Agreement, the term of Executive's employment under this Agreement (the
"Employment Period") will begin on January 1, 2003 (the "Commencement Date")
and end on the third anniversary of such Commencement Date.  Except as
provided in this Agreement, if Executive remains employed by the Company
following the expiration of the Employment Period, his employment will be
governed by the same terms and conditions applicable to similar executives of
the Company and will not be governed by any provision of this Agreement.

(b) Survival.  Upon the expiration or termination of this Agreement for any
reason, the provisions of this Agreement that by their terms survive such
expiration or termination shall continue in effect and will bind each of the
parties according to the terms thereof.  Such provisions include, without
limitation, Sections 1, 4, 5, 7, 8, 9 and 10 hereof.

2.	DUTIES.  The Company shall employ Executive during the Employment Period
as its Senior Vice President, Legal Affairs and General Counsel.  His primary
work site shall be the Company's corporate headquarters in St. Paul,
Minnesota.  During the Employment Period, excluding any periods of short-term
disability, vacation or sick leave to which he is entitled, Executive shall
perform the duties of such positions and such other duties as may be assigned
to him by the Chief Executive Officer of the Company (the "Chief Executive
Officer").  In performing such duties, Executive shall devote substantially
all of his business time, attention and effort to the affairs of the Company
and shall use his reasonable best efforts to promote the interests of the
Company.  As part of performing such duties, Executive shall comply with all
applicable policies generally in effect for employees and senior executives of
the Company.

3.	CURRENT COMPENSATION.
(a) Base Salary.  The Company shall pay Executive in accordance with the
normal payroll practices of the Company (but not less frequently than monthly)
an annual salary at a rate of $600,000 per year ("Base Salary") beginning on
the Commencement Date.

(b) Profit Sharing.  In addition to the Base Salary described in paragraph (a)
above, the Company shall pay to Executive additional variable compensation
pursuant to the Company's Executive Profit Sharing Plan.  The amount of such
additional variable compensation will depend on the future performance of the
Company, as defined in such Plan, and is not guaranteed.  Subject to the
foregoing, the number of plan shares initially assigned to Executive shall be
sufficient to produce annual planned compensation of $400,000.  The Company
shall pay such profit sharing to Executive in the form of cash, restricted
shares of common stock of the Company ("Common Shares") or a combination
thereof as determined by the Committee at such times and in such manner as is




consistent with the treatment of other senior executives of the Company and
with the provisions of such Executive Profit Sharing Plan.  If Executive's
employment with the Company ends on a date other than the end of a calendar
quarter, he shall receive a prorated amount of such profit sharing for the
calendar quarter in which his employment ends in the same manner as is
consistent with the treatment of other senior executives of the Company and
with the provisions of such Executive Profit Sharing Plan.

(c) Adjustments.  During the Employment Period, Executive's annual planned
cash compensation (consisting of the Base Salary described in paragraph (a)
above and the profit sharing described in paragraph (b) above) shall be
reviewed at least annually and may be increased from time to time as
determined by the Compensation Committee of the Company's Board of Directors
(the "Committee").

4.	SIGNING GRANTS.
(a) Cash Bonus.  The Committee has granted to Executive, effective as of the
Commencement Date, a cash signing bonus (the "Cash Bonus") in the amount of
$850,000.  The Cash Bonus will be payable in equal installments of one-third
on the Commencement Date and each of the first 2 anniversaries of the
Commencement Date, so long as Executive remains continuously employed by the
Company.  However, any unpaid balance of the Cash Bonus will become payable in
full immediately upon a Change in Control, the death of the Executive,
termination of his employment due to Disability, termination without Cause or
termination for Good Reason.  Any unpaid balance of the Cash Bonus shall
automatically be forfeited immediately upon a termination for Cause.

(b) Restricted Stock.  The Committee has granted to Executive, effective as of
the Commencement Date, 6,000 restricted Common Shares (the "Restricted
Shares").  The Restricted Shares will vest in increments of one-third on each
of the third, fifth and seventh anniversaries of the Commencement Date, so
long as Executive remains continuously employed by the Company.  However, the
Restricted Shares will vest immediately upon a Change in Control, the death of
the Executive or termination of his employment due to Disability.  In
addition, the vesting percentage of the Restricted Shares will be increased by
33-1/3% upon a termination without Cause or a termination for Good Reason.  If
the Company terminates Executive's employment for Cause or if Executive
terminates his employment (other than by reason of death, Disability or Good
Reason) prior to vesting in all the Restricted Shares, the Shares which are
not vested shall be automatically forfeited on the date of termination unless
the Committee in its sole discretion elects to vest all or any portion of the
unvested Shares.  In all other respects, the Restricted Shares shall be
subject to and governed by the terms of the Company's 2002 Management Stock
Ownership Program.

(c) Definition.  For purposes of this Section 4, the term "Change in Control"
means any of the following events:

(i)	any person (as such term is used in Rule 13d-5 under the Securities
Exchange Act of 1934) or group (as such term is defined in sections 3(a)(9)
and 13(d)(3) of the Securities Exchange Act of 1934), other than a subsidiary
or any employee benefit plan (or any related trust) of the Company or a
subsidiary, becomes the beneficial owner of 20% or more of the common shares
or of securities of the Company that are entitled to vote generally in the
election of directors of the Company ("Voting Securities") representing 20% or
more of the combined voting power of all Voting Securities of the Company;

(ii)	individuals who, as of the Commencement Date, constitute the Board of
Directors of the Company (the "Incumbent Directors") cease for any reason to
constitute at least 50% of the members of such Board; provided that any
individual who becomes a Director of the Company after the Commencement Date
whose election or nomination for election by the Company's shareholders was
approved by a majority of the Incumbent Directors (other than an election or
nomination of an individual whose initial assumption of office is in
connection with an actual or threatened "election contest" relating to the
election of the Directors of the Company (as such terms are used in rule 14a-
11 under the Securities Exchange Act of 1934), "tender offer" (as such term is
used in section 14(d) of the Securities Exchange Act of 1934) or a proposed
Merger (as defined below)) shall be deemed to be an Incumbent Director; or

(iii)	approval by the shareholders of the Company of either of the following:
(A)  a merger, reorganization, consolidation or similar transaction (any of
the foregoing, a "Merger") as a result of which the individuals and
entities who were the respective beneficial owners of common shares
and Voting Securities of the Company immediately before such Merger
are not expected to beneficially own, immediately after such Merger,
directly or indirectly, more than 50% of, respectively, the common
shares and the combined voting power of the Voting Securities of the




corporation resulting from such Merger in substantially the same
proportions as immediately before such Merger, or

(B)  a plan of liquidation of the Company or a plan or agreement for the sale
or other disposition of all or substantially all of the assets of the Company,
other than such a sale or disposition to an entity which is, directly or
indirectly more than 50% owned by the Company or an entity of which the
individuals and entities who were the respective beneficial owners of common
shares and Voting Securities of the Company immediately before such sale or
other disposition beneficially owned immediately after such sale or other
disposition directly or indirectly more than 50% of, respectively, the common
shares and the combined voting power of the Voting Securities of the
corporation to which such sale or other disposition was made.

Notwithstanding the foregoing, there shall not be a Change in Control for
purposes of this Agreement if, in advance of such event, Executive agrees in
writing that such event shall not constitute a Change in Control.

5.	STOCK OPTIONS.  In May 2003 the Committee shall grant Executive an
option (the "2003 Option") to purchase a minimum of 23,000 Common Shares at an
exercise price equal to the fair market value of a Common Share on the date of
grant.  The 2003 Option will have a term of 10 years from the date of grant,
and will become exercisable on the first anniversary of the date of grant.
However, the 2003 Option will become exercisable in full immediately upon and
may be exercised up to two years following the death of the Executive,
termination of his employment due to Disability, termination without Cause or
termination for Good Reason.  In addition, any portion of the 2003 Option that
has already become exercisable by the date of termination may be exercised up
to 90 days following a termination by the Executive without Good Reason.  In
no event, however, shall the 2003 Option be exercisable after the expiration
of its 10-year term.  The 2003 Option shall automatically expire immediately
upon a termination for Cause.  In all other respects, the 2003 Option shall be
subject to and governed by the terms of the Management Stock Ownership Program
in effect on the date of grant.  The Committee shall in its sole discretion
consider Executive for possible future grants of stock options in accordance
with the provisions of the Management Stock Ownership Program in effect at
such time.

6.	PERFORMANCE UNITS.   In February 2003 the Committee shall grant
Executive units under the Company's Performance Unit Plan with a par value
equal to $288,000 (the "Initial Performance Units").  These Initial
Performance Units will have a 3-year performance period beginning January 1,
2003 and ending December 31, 2005.  The ultimate value of the Initial
Performance Units will depend on the performance of the Company during the
performance period, and is not guaranteed.  The Initial Performance Units will
vest at the end of the 3-year performance period, so long as Executive remains
continuously employed by the Company.  However, the Initial Performance Units
will vest immediately upon the Executive's death, termination of his
employment due to Disability, termination without Cause or a termination for
Good Reason prior to the end of the 3-year performance period; provided that
in such event, the value of such Units will be limited to their par value
multiplied by the ratio of the days the Executive was employed by the Company
to the total number of days from the Commencement Date through December 31,
2005.  The Committee shall in its sole discretion consider Executive for
possible future grants of performance units in accordance with the provisions
of the Performance Unit Plan in effect at such time.

7.	OTHER BENEFITS.
(a) Retiree Medical Benefits.  The Company shall establish an opening account
balance for Executive under its retiree medical program equal to 39,000
retiree medical credits.  In recognition of such opening account balance,
Executive will be eligible to earn additional retiree medical credits under
such program only for up to an additional nine years of employment with the
Company.




(b) Vacation.  During his employment, Executive shall be entitled to earn and
receive paid vacation benefits in accordance with the Company's vacation plan
applicable to other senior executives of the Company; provided that in no
event shall Executive earn less than five weeks of vacation benefits per year.

(c) Gross Up for Excise Taxes.  In the event that any payment made to
Executive pursuant to this Agreement or otherwise is finally determined to be
subject to the excise tax imposed by section 4999 of the Internal Revenue Code
of 1986 or any similar tax payable under any federal, state or local law, then
the Company shall pay Executive an additional amount sufficient to fully
satisfy such excise tax and any additional federal, state and local income
taxes payable on the additional amount.

(d) Relocation Expenses.  To the extent not inconsistent with applicable laws,
the Company will reimburse Executive for the reasonable expenses of relocating
his primary residence to the Minneapolis-St. Paul area in accordance with the
Company's relocation policy applicable to senior executives.  This will
include assistance with the sale of Executive's principal residence (without
regard to the policy's current $500,000 value limit), reimbursement for
temporary living expenses for up to six months following the Commencement
Date, and reimbursement of the travel expenses for a reasonable number of
trips between Executive's current principal residence and St. Paul by
Executive and members of his immediate family.

(e) Life Insurance.  In lieu of participation in the 3M Senior Executive Split
Dollar Plan, 3M shall purchase term life insurance on the life of Executive
with coverage equal to three times the amount of his annual Base Salary and
planned profit sharing, subject to any conditions required by the insurer
selected by 3M (such as providing satisfactory evidence of good health).  If
and when 3M replaces such Plan with another life insurance arrangement for its
senior executives, 3M may replace the term life insurance coverage described
in this Section 7 with coverage under such new arrangement that is similar to
the coverage provided to other similarly-situated senior executives.

(f) Other Benefits.  Executive shall be eligible to receive the other benefits
and perquisites made available to similarly situated executives of the
Company, in accordance with the provisions of the applicable benefit plans and
policies.

(g) Retirement.  In accordance with the provisions of the Company's Employee
Retirement Income Plan, Executive shall be eligible to retire from employment
with the Company after five years of employment and receive all of the
retirement-related benefits and privileges (including the right to exercise
stock options granted under the Management Stock Ownership Program during the
balance of the original term thereof) available to other similarly-situated
senior executives of the Company.

8.	SUPPLEMENTAL RETIREMENT BENEFIT.
(a) Amount.  The Company will pay Executive additional pension benefits (the
"Supplemental Retirement Benefit") to supplement the pension benefits he will
be entitled to receive under the Company's pension plans.  The formula for
this Supplemental Retirement Benefit, which is expressed in the form of an
annuity payable monthly over his lifetime beginning when he attains age 62,
shall be:

One-twelfth of 45% of his highest average (4 years) annual earnings (base
salary plus profit sharing), multiplied by the following fraction, where the
numerator is the number of years (or portions thereof) Executive has been
employed by the Company (up to 9) and the denominator is 9,

minus

(ii)	the sum of the pension benefits Executive is actually receiving or is
entitled to receive under the Company's qualified and nonqualified defined
benefit pension plans, in each case after converting the benefits paid or
payable under such plans to an Actuarially Equivalent annuity payable for his
lifetime commencing at his age 62.




Once Executive has completed two years of continuous employment with the
Company, the sum of the amount determined under the above formula and the
pension benefits paid or payable monthly under the Company's pension plans
shall not be less than one-twelfth of $300,000.

(b) Vesting.  Executive will become fully vested in the Supplemental
Retirement Benefit after he has completed five years of continuous employment
with the Company.  However, the Supplemental Retirement Benefit will vest
immediately upon Executive's death, termination of his employment due to
Disability, a termination without Cause or a termination for Good Reason.  If
Executive's employment terminates for any other reason prior to his completion
of five years of continuous employment with the Company, he will forfeit and
will not receive any portion of the Supplemental Retirement Benefit other than
the $300,000 minimum benefit described in the last sentence of paragraph (a)
above (which he shall receive only if he has completed at least two years of
continuous employment with the Company).

(c) Payment.  Payment of the Supplemental Retirement Benefit shall begin at
the same time as and shall be made in the same form as Executive receives
payment of his monthly benefits from the Company's pension plans; provided,
however, that the amount of such monthly Benefit payments shall be Actuarially
Adjusted in the event payment begins before Executive has attained age 62 or
payment is made in a form other than an annuity payable over his lifetime.  In
the event Executive will not receive any benefits under the Company's pension
plans (due to his death or termination of employment prior to vesting in such
benefits), the Company shall pay the Actuarial Equivalent of such Supplemental
Retirement Benefit in a single lump sum payment promptly following such event,
or in such other form available for the payment of benefits under the
Company's pension plans as Executive may elect prior to the date that his
Supplemental Retirement Benefit vests hereunder.  For purposes of the
Supplemental Retirement Benefit, the terms "Actuarially Equivalent" or
"Actuarially Adjusted" shall mean making one benefit of equivalent value to
another benefit using the interest rate and mortality assumptions then in
effect under the Company's pension plans; provided, however, that in no event
shall this paragraph's language requiring that such Supplemental Retirement
Benefit payments be "Actuarially Adjusted" or "Actuarially Equivalent" result
in the payment of less than $300,000 of combined annual pension benefits to
Executive under this Agreement's Supplemental Retirement Benefit provisions
and the Company's pension plans once Executive has completed the two years of
continuous employment with the Company required in paragraph (a) above.  If
Executive dies prior to retiring or otherwise terminating his employment with
the Company, his surviving spouse (if any) shall be entitled to receive
payment of that portion of the Supplemental Retirement Benefit earned prior to
his date of death she would have received if Executive's employment had
terminated due to Disability on the day immediately preceding his date of
death and he had elected to receive payment of his Supplemental Retirement
Benefit in the form of an Actuarially Equivalent 50% joint and survivor
annuity.  Payments of the Supplemental Retirement Benefit will be made from
the Company's general assets, and not from any trust funding the Company's
pension plans.

9. 	TERMINATION BENEFITS.
(a) Termination without Cause or for Good Reason.  The Company may terminate
Executive's employment without Cause or Executive may terminate his employment
for Good Reason.  In such event, the Company shall pay to Executive promptly
after the date of termination a lump sum cash amount equal to (a) two times
his then current annual Base Salary and annual planned profit sharing if such
termination occurs during the first three years following the Commencement
Date, or (b) one times his then current annual Base Salary and annual planned
profit sharing if such termination occurs more than three but no more than ten
years following the Commencement Date.  Executive's right to the payment
described in the preceding sentence will be contingent upon his execution of a
general release of all claims against the Company, in a form mutually
acceptable to Executive and the Company.  In addition to the foregoing
payment, Executive shall also be entitled to receive the other benefits he has
accrued under the Company's benefit plans and programs through the date of
termination in accordance with their applicable terms.

(b) Termination for Cause, upon Disability or other than for Good Reason. During
the Employment Period and thereafter, the Company may terminate Executive's




Executive's employment for Cause or in the event of Executive's Disability,
and Executive may terminate his employment for other than Good Reason.  In
such event, Executive shall only be entitled to receive the Base Salary,
profit sharing and other benefits he has accrued through the date of
termination and Executive shall not be entitled to receive any severance
payment.

(c) Termination upon Death.  Executive's employment will automatically
terminate in the event of his death.  In such event, Executive shall only be
entitled to receive the Base Salary, profit sharing and other benefits he has
accrued through the date of termination and Executive shall not be entitled to
receive any severance payment.

(d) Exclusive Remedy.  The amounts described in this Section 9 shall be
Executive's exclusive remedy for any damages resulting from a termination of
his employment for any reason.

(e) Definitions.  For purposes of this Agreement:

(i) 	The term "Cause" means any one of the following:

(A) Executive's indictment on or conviction of any felony or a misdemeanor
involving fraud, dishonesty or moral turpitude,

(B) Executive's material breach of this Agreement, provided that such breach
will not constitute Cause if Executive cures the breach within 10 days after
delivery to the Executive of a written notice from the Chief Executive Officer
specifying the breach,

(C) the willful and intentional material misconduct by Executive in the
performance of his duties under this Agreement; provided, however, that an act
shall not be considered willful for purposes of this Agreement if it is taken
in good faith with the reasonable belief that it is in the best interests of
the Company, or

(D) the willful or intentional failure by Executive to materially comply with
a specific, lawful written directive of the Chief Executive Officer that is
consistent with normal business practice and Executive's responsibilities
under this Agreement;

The term "Disability" means a mental or physical illness or injury which
renders Executive unable or incompetent to carry out the material job
responsibilities or the material duties of Executive's position, with or
without reasonable accommodation, and which is expected to last for a duration
in excess of six months; and

(iii)	The term "Good Reason" means any one of the following events unless
Executive otherwise agrees in writing:

the Company reduces Executive's total annual planned compensation (Base Salary
plus profit sharing);

(B)	the Company's material breach of this Agreement, provided that such
breach will not constitute Cause if the Company cures the breach within 10
days after delivery to the Company of a written notice from Executive
specifying the breach,

(C)	Executive is relocated to a primary work site located outside of a 50-
mile radius of his then current work site; or

(D)	Executive is assigned duties materially inconsistent with his position
and duties described in this Agreement;

provided, however, that none of the above events will constitute Good Reason
if the Company cures such event within 10 days after delivery of a written
notice from Executive specifying the Good Reason.

10. MISCELLANEOUS.

and its execution of this Agreement, Executive has agreed to enter into and
will on the Commencement Date sign the Employee Agreement provided by the
Company.

(b) Confirmation.  By signing this Agreement, Executive confirms that he is
