Source and Availability of Raw Materials
- ----------------------------------------

FMC's natural resource requirements are primarily mineral-oriented.  Substantial
portions of requirements for ores and other raw materials, especially trona and
phosphate rock, are produced from mines in the United States on property held by
FMC under long-term leases which are subject to periodic adjustments of royalty
rates. The Company also owns land, including mineral rights, relating to an
Argentine salar from which it produces lithium. Machinery operations obtain raw
materials, principally steel and castings, from many foreign and domestic
sources. No one source is considered essential to any of the machinery
operations. The Company uses oil, gas, coal, coke, hydroelectric power and
nuclear power to meet its energy needs.

Patents
- -------

Although FMC's patents, trademarks and licenses are cumulatively important to
its business, FMC does not believe that the loss of any one or group of related
patents, trademarks or licenses would have a material adverse effect on the
overall business of FMC or on any of its business segments.

Seasonality
- -----------

FMC's businesses are not generally considered to be seasonal, except for the
Agricultural Products segment, which tends towards lower profitability in the
fourth quarter primarily due to seasonality in worldwide agricultural markets.

                                                                          Page 4

 
Competitive Conditions
- ----------------------

The industries in which FMC competes are highly competitive.  FMC competes on
the basis of product performance, service and price and is among the market
leaders with respect to most products it manufactures. FMC is the world's
largest producer of natural soda ash, a leading North American producer of
hydrogen peroxide, a leading North American producer of industrial phosphorus
chemicals and a world leader in the mining and processing of lithium products.
FMC manufactures Furadan, one of the largest selling insecticides in the world.
FMC is also the largest worldwide producer of carrageenan, microcrystalline
cellulose, and phosphate ester flame retardants. FMC also participates in many
machinery businesses, including food processing, material handling and energy
production equipment, where FMC has a significant market share.

Research and Development Expenses

In 1998, the reduction in research and development ("R&D") expenses in the
Agricultural Products segment results from the completion, in late 1997 and
early 1998, of product development cycles related to the Authority and Aim
herbicides.  The decrease in R&D expenses in the Specialty Chemicals segment
from 1997 to 1998 reflects the Company's reallocation of certain R&D resources
toward customer-focused technical support (which is included in Selling and
Administrative Expenses), as well as workforce reductions in some R&D areas.

                                                                          Page 5

Employees
- ---------

FMC employs 16,216 people in its domestic and foreign operations. Approximately
2,400 such employees are represented by collective bargaining agreements in the
United States. In 1999, three of the Company's 16 collective bargaining
agreements will expire, covering approximately 123 employees. Certain of those
contracts are currently under negotiation. FMC maintains good employee relations
and has successfully concluded virtually all of its recent negotiations without
a work stoppage. In those rare instances where a work stoppage has occurred,
there has been no material effect on consolidated sales and earnings. FMC,
however, cannot predict the outcome of future contract negotiations.

Forward Looking Statements - Safe Harbor Provisions
- ---------------------------------------------------

The Company and its representatives may from time to time make written or oral
statements that are forward-looking and provide other than historical
information, including statements contained in the Company's filings with the
Securities and Exchange Commission and in its reports to stockholders.

                                                                          Page 6

 
Whenever possible, FMC has identified these forward-looking statements by such
words or phrases such as "will likely result", "are expected to", "will
continue", "is anticipated", "is predicted", "forecast", "estimate", "project",
or similar expressions identifying "forward-looking statements" within the
meaning of the Private Securities Litigation Reform Act of 1995.  Such forward-
looking statements reflect the Company's best judgment based on current
information and are subject to certain risks and uncertainties that could cause
actual results to differ materially from those expressed in, or implied by,
these statements. The Company wishes to caution readers not to place undue
reliance on any such forward-looking statements, which speak only as of the date
made. In connection with the "safe harbor" provisions of the Private Securities
Litigation Reform Act of 1995, the Company is hereby identifying important
factors that could affect the Company's financial performance and could cause
the Company's actual results for future periods to differ materially from any
opinions or statements expressed with respect to future periods in any current
statements.

Among the factors that could have an impact on the Company's ability to achieve
its operating results and growth plan goals are:

 .  Significant price competition, particularly among the Company's competitors
   in chemical businesses

 .  The impact of unforeseen economic and political changes in the international
   markets where the Company competes, including currency exchange rates, war,
   civil unrest, inflation rates, recessions, trade restrictions, foreign
   ownership restrictions and economic embargos imposed by any of 24 foreign
   countries in which FMC does business or the United States, and other external
   factors over which the Company has no control

 .  The impact of significant changes in domestic interest rates or taxation
   rates

                                                                          Page 7

 
 .  Increases in ingredient or raw material prices compared to historical levels,
   or shortages of ingredients or raw materials

 .  Inherent risks in the marketplace associated with new product introductions
   and technologies, particularly in agricultural and specialty chemicals

 .  Changes in capital spending by customers in the petroleum exploration service
   and airline industries

 .  Risks associated with developing new manufacturing processes, particularly
   with respect to complex chemical products

 .  The ability of the Company to integrate possible future acquisitions into its
   existing operations

 .  The impact of freight transportation delays beyond the control of the Company

 .  The inability of governmental entities or the Company or its suppliers,
   service providers or customers to remedy potential problems with information
   systems related to the arrival of the year 2000

 .  Risks associated with joint venture, partnership or limited endeavors in
   which the Company may be responsible at least in part for the acts or
   omissions of its partners

 .  Stock market conditions

 .  Risks derived from unforeseen developments in industries served by the
   Company such as weather patterns in the agricultural sector, political or
   economic changes in the energy industries, and other external factors over
   which the Company has no control

 .  Environmental liabilities that may exceed current reserves and estimated loss
   contingencies that may arise in the future and that are not covered by
   insurance or indemnity

                                                                          Page 8

 
 .  Increased competition in the hiring and retention of employees


The Company cautions that the foregoing list of important factors may not be
all-inclusive, and it specifically declines to undertake any obligation to
publicly revise any forward-looking statements that have been made to reflect
events or circumstances after the date of such statements or to reflect the
occurrence of anticipated or unanticipated events.

With respect to forward-looking statements set forth in the "Legal Proceedings"
section, some of the factors that could affect the ultimate disposition of those
contingencies are changes in applicable laws, the development of facts in
individual cases, settlement opportunities and the actions of plaintiffs, judges
and juries.


ITEM 2.    PROPERTIES

FMC leases executive offices in Chicago and administrative offices in
Philadelphia.  The Company operates 107 manufacturing facilities and mines in 25
countries.  Its major research facility is in Princeton, NJ.  FMC holds mining
leases on shale and ore deposits in Idaho to supply its phosphorus plant in
Pocatello, and owns substantial phosphatic ore deposits in Rich County, Utah.
Trona ore, used for soda ash production in Green River, WY, is mined primarily
from property held under long-term leases.  FMC owns the land and mineral rights
to the Salar del Hombre Muerto lithium reserves in Argentina.  Many of FMC's
chemical plants require the basic raw materials which are provided by these FMC-
owned or leased mines, without which other sources would have to be obtained.
With regard to FMC's mining properties operated under long-term leases, no
single lease or related group of leases is material to the businesses of the
Company as a whole.

Most of FMC's plant sites are owned, with an immaterial number of them being
leased.  FMC believes its properties and facilities meet present requirements
and are in good 

                                                                          Page 9

ITEM 3.    LEGAL PROCEEDINGS

Environmental Proceedings
- -------------------------

FMC has signed a Consent Decree with the EPA (Region 10) and the United States
Department of Justice ("DOJ") to settle outstanding alleged violations of the
Resource Conservation Recovery Act ("RCRA") at FMC's Phosphorus Chemicals
("PCD") plant in Pocatello, Idaho. The RCRA Consent Decree was lodged in the
United States District Court for the District of Idaho on October 16, 1998, and
the public comment period closed on December 18, 1998.  Public comments were
received, and the DOJ and the EPA must respond to the public comments before the
RCRA Consent Decree can be entered by the Court.  The RCRA Consent Decree
provides for injunctive relief covering remediation expense for closure of
existing ponds, estimated at $50 million, and approximately $43 million of
capital costs for waste treatment and other compliance projects; these amounts
will be expended over approximately four (4) years.  FMC also will spend
approximately $65 million over the next four (4) years to conduct a number of
supplemental environmental projects.  These projects include approximately $63
million in capital costs for air quality improvements, and an additional $2
million for health studies with the Shoshone-Bannock Tribes, since the plant is
located on tribal land.  FMC has also paid a penalty of $11.8 million.  As
described in Note 4 to the 

                                                                         Page 10

 
consolidated financial statements (page 42 of the 1998 Annual Report to
Stockholders), an expected increase in capital costs for environmental
compliance contributed to impairment in the value of PCD's assets during the
fourth quarter of 1997.

In addition, FMC has signed a second Consent Decree with the EPA, which has yet
to be lodged in court.  On June 6, 1998, the EPA issued a Record of Decision
("ROD") which addresses previously-closed ponds on the FMC portion of the
Eastern Michaud Flats Superfund site, which includes FMC's PCD Pocatello, Idaho,
facility.  The remedy the EPA selected in the ROD is a combination of capping,
surface runoff controls and institutional controls for soils, with a contingency
for extraction and recycling for hydraulic control of groundwater.  FMC believes
its reserves for current and future environmental costs adequately provide for
the estimated costs of the Superfund remediation plan for the site and the
expenses related to the October 16, 1998 RCRA Consent Decree described above.

In a separate matter, FMC has reached an agreement in principle with the EPA and
the DOJ regarding settlement of past costs and future clean-up work at the
discontinued fiber manufacturing site in Front Royal, Virginia. The parties are
currently negotiating the specific terms of the agreement in principal and the
final Consent Decree. The anticipated costs associated with this agreement in
principle are the largest component of the fourth quarter 1998 environmental
charge to discontinued operations of $70.0 million, net of contractual
recoveries as described in Note 3 to the consolidated financial statements
(pages 41-42 of the 1998 Annual Report to Stockholders).

See Note 14 to the consolidated financial statements (pages 49-50 of the
1998 Annual Report to Stockholders) for a discussion of legal proceedings
against other Potentially Responsible Parties and insurers for contribution
and/or coverage with respect to environmental remediation costs.

Other
- -----

On April 14, 1998 a jury returned a verdict against the Company in the amount of
$125.0 million in conjunction with a federal False Claims Act action, in which
Mr. Henry 

                                                                         Page 11

 
Boisvert filed and ultimately took to trial allegations that the Company had
filed false claims for payment in connection with its contract to provide
Bradley Fighting Vehicles to the United States Army between 1981 and 1996. Under
law, portions of the jury verdict were subject to doubling or trebling. On
December 24, 1998, the U.S. District Court for the Northern District of
California entered judgment for Mr. Boisvert in the amount of approximately $87
million, or approximately $300 million less than the maximum judgment possible
under the jury verdict. The reduction resulted from several rulings by the
District Court in favor of the Company in post-trial motions. Cross-appeals to
the U.S. Court of Appeals for the Ninth Circuit are now pending. Both sides are
asserting arguments on appeal, and a number of those arguments, if successful,
would alter or eliminate the amount of the existing judgment. Any legal
proceeding is subject to inherent uncertainty, and it is not possible to predict
how the appellate court will rule. Therefore, it is the position of the
Company's management based on a review, including a review by outside counsel,
that it is not possible to estimate the amount of a probable loss, if any, to
the Company that might result from some adverse aspects of the judgment in this
action ultimately standing against the Company. Accordingly, no provision for
this matter has been made in the Company's consolidated financial statements.
