when expressed as a straight life annuity with sixty monthly payments
guaranteed, is equal to his Normal Retirement Benefit reduced by his Normal

a Change of Control, all accrual of benefits under this Plan shall cease and
each Participant shall become fully vested in his accrued benefits as of the
date of the Change of Control, even if he is not fully vested under the
Retirement Plan.  Each Participant shall be paid, at the Participant's
election, (a) upon the Change of Control or (b) upon the Participant's
termination of Employment occurring after the Change of Control.  If the
Participant elects to receive payment upon the Change of Control, payment shall
be made in the form of a lump sum distribution which is the actuarial
equivalent of such accrued benefits (using the same actuarial assumptions as
are used in computing equivalent actuarial values under the Retirement Plan).
If the Participant elects to receive payment upon the termination of
Employment occurring after the Change of Control, the Participant shall make an
additional election to receive payment in the form of either a lump sum
distribution or the form of benefit provided under Section IV.  At the
commencement of participation in the Plan, each Participant shall make an
irrevocable election as to the timing and form of any payments due under this
Section VI.

                                SECTION VII
                           FORFEITURE OF BENEFITS

          If any Participant entitled to a benefit under the Plan is discharged
for cause, or enters into competition with the Company, or interferes with the
relations between the Company and any customer, or engages in any activity that
would result in any decrease of, or loss in, sales by the Company, the rights
of such Participant to a benefit under the Plan, including the rights of a
Surviving Spouse to a benefit, will be forfeited, unless the Committee
determines that such activity is not detrimental to the best interests of the
Company.  However, if the individual ceases such activity and notifies the
Committee of this action, then the Participant's right to receive a benefit,
and any right of a Surviving Spouse to a benefit, may be restored within 60
days of said notification, unless the Committee in its sole discretion
determines that the prior activity has caused serious injury to the Company,
which determination shall be final and conclusive.

                                SECTION VIII
                      ADMINISTRATION AND CLAIMS PROCEDURE

          A.     The Committee shall construe, interpret and administer all
provisions of the Plan and a decision of a majority of the members of the
Committee shall govern.
          B.     A decision of the Committee may be made by a written document
signed by a majority of the members of the Committee or by a meeting of the
Committee. The Committee may authorize any of its members to sign documents or
papers on its behalf.
          C.     The Committee may appoint such agents, who need not be
members of the Committee, as it may deem necessary for the effective exercise
of its duties, and may, to the extent not inconsistent herewith, delegate to
such agents any powers and duties, both ministerial and discretionary, as the
Committee may deem expedient and appropriate.
          D.     No member of the Committee shall make any decision or take any
action covering exclusively his own benefits under the Plan, but all such
matters shall be decided by a majority of the remaining members of the
Committee or, in the event of inability to obtain a majority, by the Board of
Directors of the Company.
          E.     A Participant who believes that he is being denied a benefit
to which he is entitled (hereinafter referred to as "Claimant") may file a
written request for such benefit with the Committee setting forth his claim.
The request must be addressed to: Compensation and Human Resources Committee,
Emerson Electric Co., 8000 West Florissant, St. Louis, Missouri 63136.
          F.     Upon receipt of a claim the Committee shall advise the
Claimant that a reply will be forthcoming within 90 days and shall in fact
deliver such reply in writing within such period. The Committee may, however,
extend the reply period for an additional 90 days for reasonable cause.  If the
claim is denied in whole or in part, the Committee will adopt a written opinion
using language calculated to be understood by the Claimant setting forth:
               1.     the specific reason or reasons for denial,
               2.     the specific references to pertinent Plan provisions on
          which the denial is based,
               3.     a description of any additional material or information
          necessary for the Claimant to perfect the claim and an explanation
          why such material or such information is necessary,
               4.     appropriate information as to the steps to be taken if
          the Claimant wishes to submit the claim for review, and
               5.     the time limits for requesting a review under Subsection
          G and for the review under Subsection H.
          G.     Within sixty days after the receipt by the Claimant of the
written opinion described above, the Claimant may request in writing that the
Chief Executive Officer of the Company review the determination of the
Committee. Such request must be addressed to: Chief Executive Officer, Emerson
Electric Co., 8000 West Florissant, St. Louis, Missouri 63136. The Claimant or
his duly authorized representative may, but need not, review the pertinent
documents and submit issues and comments in writing for consideration by the
Chief Executive Officer.  If the Claimant does not request a review of the
Committee's determination by the Chief Executive Officer within such sixty-day
period, he shall be barred and estopped from challenging the Committee's
determination.
          H.     Within sixty days after the Chief Executive Officer's receipt
of a request for review, he will review the Committee's determination. After
considering all materials presented by the Claimant, the Chief Executive
Officer will render a written opinion, written in a manner calculated to be
understood by the Claimant, setting forth the specific reasons for the decision
and containing specific references to the pertinent Plan provisions on which
the decision is based. If special circumstances require that the sixty-day time
period be extended, the Chief Executive Officer will so notify the Claimant and
will render the decision as soon as possible but not later than 120 days after
receipt of the request for review.

                                SECTION IX

benefits payable or to be payable under this Plan.
          C.     Incapacity.  If, in the opinion of the Committee, a person to
whom a benefit is payable is unable to care for his affairs because of illness,
accident or any other reason, any payment due the person, unless prior claim
therefor shall have been made by a duly qualified guardian or other duly
appointed and qualified representative of such person, may be paid to some
member of the person's family, or to some party who, in the opinion of the
Committee, has incurred expense for such person. Any such payment shall be a
payment for the account of such person and shall be a complete discharge of any
liability.
          D.     Employee Rights.  The Employer, in adopting this Plan, shall
not be held to create or vest in any Employee or any other person any benefits
other than the benefits specifically provided herein, or to confer upon any

          F.     Unfunded Plan.  The Plan shall be unfunded.  All payments to a
Participant under the Plan shall be made from the general assets of the
Employer. The rights of any Participant to payment shall be those of an
unsecured general creditor of the Company.
          G.     Company Rights.  The Company reserves the right to amend or
terminate the Plan.  Each Employer may terminate its participation in the Plan
at any time.
          H.     Reemployment.  If a Participant is receiving benefits under
the Plan and is re-employed by an Employer, benefits shall cease until he is no
longer employed by an Employer.
          I.     Governing Law.  The Plan shall be governed and construed
according to the laws of the State of Missouri.
               IN WITNESS WHEREOF, Emerson Electric Co. has caused this
Amendment to be executed by one of its duly authorized officers this 4th day
of October, 1999.
