                                FMC Corporation
                           Executive Severance Plan
                           ------------------------

           (As Amended and Restated Effective as of January 1, 2000)

1.   History and Purpose.  The Company adopted the Plan in 1983 and amended and
     -------------------
restated the Plan in 1997. The Plan is hereby amended and restated as of January
1, 2000. The purpose of the Plan is to assure the Company that it will have the
continued dedication and the availability of objective advise and counsel from
key executives of the Company, notwithstanding the possibility, threat or
occurrence of a bid to take over control of the Company

     The Board of Directors believes it is imperative that, if the Company
receives any proposals from a third person concerning a possible business
combination with the Company or the acquisition of the Company's equity
securities, both the Company and the Board of Directors be able to rely upon key
executives to continue in their positions and to be available for advice,
without concern that those individuals might be distracted by their own personal
financial situations and the risks to themselves created by the proposal.

     If the Company receives any such proposal, key executives will be called
upon to assist in assessing the proposal, to advise management and the Board of
Directors regarding whether the proposal is in the best interest of the Company
and its stockholders, and to take such other actions as the Board of Directors
might deem appropriate.

2.   Eligible Executives.  The following individuals will be Participants:
     -------------------

     a.  the Chairman of the Board of Directors;

     b.  the President, the Executive Vice Presidents, and the Senior Vice
     Presidents of the Company;

     c.  the Group and Regional Managers of the Company;

     d.  other officers of the Company, except Assistant Secretaries and
     Assistant Treasurers;

     e.  Company Division Managers of the Company; and

     f.  other key executives of the Company and its Subsidiaries who are from
     time to time named as Participants by the Committee in its sole discretion.

A Participant will cease to be a Participant if and when the Committee
determines he or she should no longer be a Participant. The Committee will not
determine that a Participant has ceased to be a Participant during any period
that the Company knows a Person has taken steps reasonably calculated to effect
a Change in Control, and before the Board of Directors has determined that that
Person has abandoned or terminated its efforts to effect a Change in Control.

                                      -1-
<PAGE>

The decision of the Board of Directors that a Person has abandoned or terminated
its efforts to effect a Change in Control will be conclusive and binding on all
Participants.

3.   Terms of the Plan.  The terms of the Plan are as set forth in the forms of
     -----------------
agreement attached to this Plan, with Form IA applicable to Tier IA
Participants, Form I applicable to Tier I Participants, Form II applicable to
Tier II Participants and Form III applicable to Tier III Participants.

The Company will enter into Executive Severance Agreements with each Participant

or a Participant has not executed an Agreement, the Participant will be entitled
to participate in the Plan on the terms and conditions set forth in the form of

     then outstanding voting securities eligible to elect directors of the

     Corporation) except to the extent that such ownership of the Company
     existed prior to the Business Combination and (iii) at least a majority of
     the members of the board of directors of the Parent Corporation (or, if
