         FMC Corporation Salaried Employees' Equivalent Retirement Plan
         --------------------------------------------------------------
              (As amended and restated effective as of May 1, 2001)


         Section 1. Establishment and Purposes of the Plan. The FMC Salaried
                    --------------------------------------
Employees' Equivalent Retirement Plan (the "Plan") was established effective
January 1, 1976 by FMC Corporation, a Delaware corporation ("Company"). The
purpose of the Plan is to provide employees of the Company and its affiliated
companies that have adopted the Plan (collectively, the "Employer") with the
retirement benefits they would have received under Part I - Salaried and
Non-Union Hourly Employees' Retirement Plan of the FMC Corporation Employees'
Retirement Program (the "Salaried Retirement Plan"), but for the limitations of
Sections 401(a)(17) and 415 of the Internal Revenue Code of 1986, as amended
(the "Code"), and but for the fact that amounts an employee defers under the FMC
Corporation Non-Qualified Savings and Investment Plan are not pensionable
earnings under the Salaried Retirement Plan. This document represents an
amendment and restatement of the Plan, effective as of May 1, 2001.

         Section 2. Participants. An employee of any Employer who is an active
                    ------------
participant in the Salaried Retirement Plan will become a "Participant" on the
day he or she becomes entitled to an Excess Benefit under Section 3. Once an
individual is a Participant, he or she will remain a Participant until his or
her entire Excess Benefit has been paid.

         Section 3. Excess Benefit. Each employee of an Employer who is an
                    --------------
active participant in the Salaried Retirement Plan will be entitled to receive
an "Excess Benefit" equal to the amount, if any, by which his or her accrued
benefit under the Salaried Retirement Plan is reduced:

         (a)   to comply with the limitations of Section 415 of the Code;

         (b)   because his or her pensionable earnings exceed the annual
               compensation limit under Code Section 401(a)(17), as adjusted
               (for 2001, $170,000); and

         (c)   because deferred compensation is not included in the definition
               of pensionable earnings under the Salaried Retirement Plan.

If the Participant's Excess Benefit is paid in a form other than the normal form
of benefit under the Salaried Retirement Plan, his or her Excess Benefit will be
converted to the form of benefit in which it is paid, using the same actuarial
assumptions and methods as are used to determine actuarial equivalence under the
Salaried Retirement Plan.

         Section 4. Funding. The amount of a Participant's Excess Benefit, if
                    -------
any, will be determined at the time the Participant becomes entitled to receive
a retirement benefit under the Salaried Retirement Plan, or at another time
determined by the Committee (as defined in Section 7) in its sole discretion,
according to rules of uniform application. Neither the Company

<PAGE>

nor any Employer is required to segregate on its books or elsewhere any amount
to be used to pay Excess Benefits, and no accounts will be maintained for
Participants under the Plan. This Plan will be unfunded, and Plan benefits will
be payable only from the general assets of the Company or any Employer. Each
Participant has only the rights of an unsecured creditor of the Company or any
Employer, as to his or her Excess Benefit.

     Section 5. Establishment of Trust. The Company may, in its sole discretion,
                ----------------------
establish a grantor trust in order to accumulate assets to pay Plan obligations.
The assets and income of any trust established under this Plan will be subject
to the claims of the Company's creditors (and those of any Employer, but only to
the extent they are attributable to the contributions of such Employer or
required by law) in the event of the Company's (or any Employer's) bankruptcy or
insolvency, and the trust document will specifically contain language to that
effect, and language specifying the mandatory procedure for the Company to
notify the trustee of bankruptcy or insolvency. The establishment or maintenance
of a trust will not affect the Company's (or any Employer's) liability to pay
Plan benefits, except as and to the extent amounts from the trust are actually
used to pay a Participant's Plan benefits. If the Company does establish a trust
under the Plan, the Company will determine how much will be contributed to the
trust and when, and trust assets will be invested in accordance with the terms
of the trust.

A Participant will have no direct or secured claim in any asset of the trust, or
in specific assets of the Company or any Employer, and will have the status of a
general unsecured creditor for any amounts due under this Plan.

     Section 6. Payment of Excess Benefit. Except as described below, a
                -------------------------
Participant's Excess Benefit will be paid to him or her (or, if he or she dies,
to his or her beneficiary) at the same time and in the same manner as his or her
accrued benefit under the Salaried Retirement Plan. A Participant's beneficiary
under this Plan will be the same person or persons as his or her beneficiary
under the Salaried Retirement Plan. Except as described below, no Participant
will be required or permitted to make any election or designation, including but
not limited to a payment election or a beneficiary designation, under this Plan.
Instead, each election or designation a Participant makes under the Salaried
Retirement Plan will apply to the Participant's Excess Benefit.

Effective for distributions beginning on or after January 1, 1998, a Participant
may elect a lump sum distribution of his or her Excess Benefit. A lump sum will
be paid as of the last day of the sixth calendar month after the calendar month
in which the Participant terminated employment with the Company and all other
Employer, or at such other time as the Committee determines.

Effective for distributions beginning on or after August 1, 1999, the Committee
may, in its sole discretion, give a Participant the ability to elect a special
annuity distribution option whereby the Company will purchase an annuity
contract to pay the Participant's Excess Benefit at the same time and in the
same manner as his or her accrued benefit under the Salaried Retirement Plan are
to be paid.

Notwithstanding anything herein to the contrary, the Committee may on its own
initiative authorize the Company to distribute to any Participant (or, if the
Participant has died, to his or

                                      -2-

<PAGE>

her designated beneficiary) all or any part of the Participant's Excess Benefit.
Payment under the preceding sentence is specifically authorized if there is a
change in tax law, a published ruling or a similar announcement issued by the
Internal Revenue Service, a Treasury Regulation, a decision by a court of
competent jurisdiction involving a Participant or designated beneficiary or a
closing agreement involving a Participant, that the Committee determines will
cause the Participant to have or recognize income for federal income tax
purposes as to Excess Benefits payable under this Plan.

     Section 7.  Administration of the Plan. This Plan will be administered by
                 --------------------------
the FMC Corporation Compensation and Organization Committee (the "Committee").
The Committee has all necessary power to administer the Plan, including the
authority and duty to interpret and apply the Plan's terms, adopt any rules or
regulations the Committee deems necessary or desirable to operate the Plan, make
whatever determinations are permitted or required to maintain or administer the
Plan and take any other actions that prove necessary to administer the Plan
properly, in accordance with its terms. Any decision of the Committee as to any
matter within its authority will be final, binding and conclusive upon the
Company, each Employer, and each Participant, former Participant, beneficiary or
other person claiming under or through any Participant or beneficiary. An action
of the Committee regarding a particular Participant will not be binding on the
Committee regarding an action to be taken as to any other Participant. A member
of the Committee may be a Participant, but he or she may not participate in any
decision that directly affects his or her rights under the Plan, or the
computation of his or her Excess Benefit. Each determination required or
permitted under the Plan will be made by the Committee in its sole and absolute
discretion. The Committee may delegate some or all of its Plan duties or
responsibilities.

     Section 8.  Amendment and Termination. The Company may amend or terminate
                 -------------------------
the Plan by action of its Board of Directors, or by action of an officer or
Company employee or committee authorized by the Company's Board of Directors to
amend the Plan. Any Employer may terminate its participation in the Plan at any
time by appropriate action, in its discretion. The Plan will automatically
terminate as to any Employer upon termination of the Employer's participation in
the Salaried Retirement Plan. Notwithstanding the foregoing, no Plan amendment
or termination may adversely affect the right of a Participant (or of his or her
beneficiary) to a benefit accrued under this Plan before the date the amendment
is adopted or effective, whichever is later.

     Section 9.  Employment. Nothing in this Plan will be deemed to give any
                 ----------
person the right to remain in the employ of the Company, any Employer or any of
its affiliates, or affect the right of the Company, any Employer or any of its
affiliates to terminate or change the terms of any Participant's employment,
with or without cause. By accepting any payment under this Plan, each
Participant, former Participant and designated beneficiary and each person
claiming under or through a Participant, former Participant or designated
beneficiary, is conclusively bound by any action or decision taken or made under
the Plan by the Committee, the Company or any Employer.

     Section 10. Withholding for Taxes. Notwithstanding anything contained in
                 ---------------------
this Plan to the contrary, any Employer will withhold from any distribution or
deferral under the

                                      -3-

<PAGE>

Plan whatever amount or amounts it is required to withhold to comply with the
tax withholding provisions of the Code or any state income tax act for purposes
of paying any income, estate, inheritance, employment or other tax attributable
to any amounts distributable under the Plan.

     Section 11. Immunity of Committee Members. The members of the Committee may
                 -----------------------------
rely upon any information, report or opinion supplied to them by any officer of
an Employer or any legal counsel, independent public accountant or actuary, and
will be fully protected in relying on any such information, report or opinion.
No member of the Committee will have any liability to the Company, any Employer
or any Participant, former Participant, beneficiary, person claiming under or
through any Participant or beneficiary, or other person interested or concerned
in connection with any Plan decision made by that member of the Committee, so
long as the decision was based on any such information, report or opinion, and
the Committee member relied on it in good faith.

     Section 12. Action by Employer. Any action required or permitted to be
                 ------------------
taken under the Plan by an Employer must be taken by its board of directors, by
a duly authorized committee of its board of directors, or by a person or persons
authorized by its board of directors or an authorized committee.

     Section 13. Effect on Other Employee Benefit Plans. Compensation accrued
                 --------------------------------------
under this Plan will not be included in the Participant's compensation or
earnings for purposes of computing benefits under any other employee benefit
plan maintained or contributed to by the Company or any Employer, except as and
to the extent required under the terms of that employee benefit plan or
applicable law.

     Section 14. Non-Alienation of Benefits. A Participant's rights to Excess
                 --------------------------
Benefits under the Plan cannot be granted, transferred, pledged or otherwise
assigned, in whole or in part, by the voluntary or involuntary acts of any
person, or by operation of law, and will not be liable or taken for any
obligation of the Participant. Any attempted grant, transfer, pledge or
assignment of a Participant's rights to Plan benefits will be null and void and
without any legal effect.

     Section 15. Employer Liability. Each Employer is liable to pay the Plan
                 ------------------
benefits earned or accrued for its eligible employees who are Participants. With
the consent of the Company's Board of Directors (or of a duly appointed delegate
of the Board of Directors), any Employer may assume any other Employer's Plan
liabilities and obligations. To the extent that an Employer assumes another
Employer's Plan liabilities or obligations, the second Employer will be released
from any continuing obligation under the Plan. At the Company's request, a
Participant, former Participant or designated beneficiary will sign any
documents reasonably required by the Company to effectuate the purposes of this
Section 15.

     Section 16. Notices. Any notice required to be given by the Company, an
                 -------
Employer or the Committee must be in writing and must be delivered in person, by
registered mail, return receipt requested, or by regular mail, telecopy or
electronic mail. Any notice given by mail will be deemed to have been given on
the date it was mailed, correctly addressed to the last known address of the
person to whom the notice is to be given.

                                      -4-

     Section 17. Gender, Number and Headings. Except where the context otherwise
                 ---------------------------
requires, in this Plan the masculine gender includes the feminine, the feminine
includes the masculine, the singular includes the plural, and the plural
includes the singular. Headings are inserted for convenience only, are not part
of the Plan, and are not to be considered in the Plan's construction.

     Section 18. Controlling Law. The Plan will be construed according to the
                 ---------------
internal laws of Delaware to the extent they are not preempted by any applicable
federal law.

     Section 19. Successors. The Plan is binding on all persons entitled to
                 ----------
benefits under it, on their respective heirs and legal representatives, on the
Committee and its successor, and on any Employer and its successor, whether by
way of merger, consolidation, purchase or otherwise.

     Section 20. Severability. If any provision of the Plan is held to be
                 ------------
illegal or invalid for any reason, that illegality or invalidity will not affect
the remaining provisions of the Plan, and the Plan will be enforced and
administered, from that point forward, as if the invalid provisions had never
been part of it.

     Section 21. Subsequent Changes. All benefits to which any Participant,
                 ------------------
beneficiary or other person is entitled under this Plan will be determined
according to the terms of the Plan as in effect when the Participant ceases to
be an employee for purposes of the Salaried Retirement Plan, and will not be
affected by any subsequent changes in Plan provisions, unless the Participant
again becomes an employee, or unless and to the extent the subsequent change
expressly applies to the Participant, his or her beneficiary, or other person
claiming through or on behalf of the Participant or beneficiary.

     Section 22. Benefits Payable to Minors, Incompetents and Others. If any
                 ---------------------------------------------------
benefit is payable to a minor, an incompetent, or a person otherwise under a
legal disability, or to a person the Committee reasonably believes to be
physically or mentally incapable of handling and disposing of his or her
property, the Committee has the power to apply all or any part of the benefit
directly to the care, comfort, maintenance, support, education or use of the
person, or to pay all or any part of the benefit to the person's parent,
guardian, committee, conservator or other legal representative, to the
individual with whom the person is living, or to any other individual or entity
having the care and control of the person. The Plan, the Committee, the Company
and any Employer and their employees and agents will have fully discharged their
responsibilities to the Participant or beneficiary entitled to a payment by
making payment under this Section 22.

     IN WITNESS WHEREOF, the Company has caused this Plan to be executed in its
name and behalf as of this 1st day of May, 2001.
