ITEM 1. BUSINESS
 
GENERAL
 
     The principal businesses of ChemFirst Inc. (the "Company") involve the
production of electronic and other specialty chemicals for use in the
semiconductor industry and in agricultural, pharmaceutical, polymer,
photographic and photosensitive applications, as well as the production of
polyurethane chemicals. The Company has reclassified the engineered products and
services operation and the steel operation as discontinued operations pending
disposition of these businesses. It is anticipated that the disposition of the
engineered products and service business will take place during 1999. The
Company also plans to divest the steel business in 1999, although adverse
industry conditions have hampered this effort.
 
     At March 1, 1999, the Company had 1,087 employees, which includes employees
of the parent company and all subsidiaries.
 
  Recent History
 
     The Company was incorporated in Mississippi in 1983 under the name Omnirad,
Inc., as a wholly-owned subsidiary of First Mississippi Corporation ("First
Mississippi"). In November 1996, in anticipation of the Distribution (as defined
below), the Company's name was changed from Omnirad, Inc. to ChemFirst Inc. On
December 23, 1996 (the "Distribution Date"), First Mississippi contributed all
of its assets and subsidiaries, other than those relating to its fertilizer
business, to the Company, which at that time was a wholly owned subsidiary of
First Mississippi and had engaged in no activities during the previous five
years. First Mississippi then spun off the Company in a tax-free distribution of
the Company's common stock to First Mississippi shareholders (the
"Distribution") on the Distribution Date. The Distribution occurred immediately
prior to and in connection with the merger of First Mississippi with a wholly
owned subsidiary of Mississippi Chemical Corporation on December 24, 1996,
pursuant to an Agreement and Plan of Merger and Reorganization dated as of
August 27, 1996. The Company has operated as a publicly held entity since the
Distribution Date. Prior to the Distribution Date, the Company's subsidiaries
were subsidiaries of First Mississippi and the Company's operations were
conducted through subsidiaries of First Mississippi.
 
  Recent Developments
 
     On December 31, 1997, the Company acquired the acylation derivatives
business of Clariant Corporation. This business is conducted through TriQuest,
L.P., a limited partnership in which the Company owns an 87.5% interest, with
the remaining 12.5% interest owned by former members of Clariant Corporation's
acylation derivatives management group who are also employees of TriQuest. This
acylation derivatives business is involved in the development and marketing of
derivatives of 4-hydroxyacetophenone for deep ultraviolet ("DUV") photoresist
resin applications for advanced integrated circuits with line geometries of 0.25
microns and below and for polymer additives and specialty adhesives. Also on
December 31, 1997, the Company acquired certain chemical mechanical
planarization ("CMP") assets of Baikowski International Corporation, a
subsidiary of Baikowski Chimie, SA, and the CMP assets of Moyco Technologies,
Inc. and its affiliate, Sweet Pea Technologies, Inc. The acquisition of these
CMP assets provided the Company with an entrance into the CMP market, which
includes mechanical polishing of silicon wafers utilizing a slurry of abrasives
and chemicals to produce a flatter surface for shorter wavelength lithography.
Acylation derivatives and CMP are included in the Company's Electronic and Other
Specialty Chemicals segment.
 
     On January 22, 1998, the Company sold its 50% interest in Power Sources,
Inc. ("PSI") to Trigen Energy Corporation ("Trigen") for approximately $20.0
million. As of January 21, 1999, there are contingencies specified in the
purchase and sale agreement with Trigen that could result in the Company
refunding as much as $750,000 of the proceeds referenced above, and accordingly,
the Company has classified these proceeds as deferred revenue pending resolution
of the contingencies. The Company no longer has an ownership interest in PSI.
The Company's disposition of its interests in PSI and the planned disposition of
the
 
                                        3

engineered products and services business and the steel business is in
furtherance of the Company's strategy to focus on chemicals.

ELECTRONIC AND OTHER SPECIALTY CHEMICALS
 
  General
 
     The Company's Electronic and Other Specialty Chemicals segment produces
specialty chemicals for use by others in electronic, agricultural,
pharmaceutical, polymer and photosensitive applications. These chemicals are
typically produced by multi-step batch processing. These products are sold both
on specification and performance and must typically be qualified for use by the
customer in addition to meeting certain specifications. The chemicals in this
segment are sold in smaller volumes and have a higher value added component than
those associated with the polyurethane chemicals. Another commonality of the
chemicals sold in this segment is the Company's focus on applied research.
Whereas the primary focus for many of the Company's customers in this segment is
on basic discovery, much of the Company's focus is on development of products
and processes for our customers' next generation semiconductors, pharmaceutical,
agricultural or consumer products. These chemicals are produced at facilities in
Hayward, California, East Kilbride, Scotland, Pascagoula, Mississippi, Tyrone,
Pennsylvania and Dayton, Ohio.
 
     Purchasers of electronic chemicals, who are typically end-users, acquire
the product to achieve a specific performance objective. As with the other
specialty chemicals, these chemicals have very specific uses, although the
customer base is often larger than for other specialty chemicals. The production
and sale of these chemicals are labor intensive and are usually dependent on
highly technical proprietary formulae and a sophisticated, well-trained
applications engineering staff. The Company's electronic chemicals are used in
the semiconductor and related industries. These chemicals include organic
post-metal cleaning solutions which remove photoresist and dry-etch residue
during the manufacture of semiconductors, post-dry-etch polymer removers, deep
ultraviolet resins for production of photoresists, and other performance
chemicals and
 
                                        4
<PAGE>   5
 
materials for cleaning and polishing silicon wafers in semiconductor
manufacturing. The Company's electronic and other specialty chemicals accounted
for approximately 59%, 60% and 61% of the Company's consolidated sales for 1998,
1997 and 1996, respectively.
 
     Most of the Company's other specialty chemicals are sold to a narrow base
of customers, which are either end-users or producers of performance chemicals.
Because of their specialized, complex molecular structure, these products are
designed for specific end-use for one or two customers and significant technical
service is expected by the customer. The key to successful production of these
specialty chemicals is identifying the markets for the product and developing a
chemical synthesis production route and process. These chemicals are sold as
intermediates to other specialty chemical producers and to agricultural,
electronic, pharmaceutical, polymer and cosmetics companies for use in
herbicides, a plant growth regulator, plastic curatives, cosmetics, protease
inhibitors, rubber processing chemicals, optical brighteners, dyestuffs and
pigments, and photoinitiators. The Company makes substantial sales of a
herbicide ingredient to one manufacturer under an agreement that will expire in
2002.
 
     The Company owns and operates electronic chemical manufacturing facilities
in Hayward, California and East Kilbride, Scotland. The Company's 65,000 square
foot California facility includes offices, research and development labs and
manufacturing and packaging facilities. The California facility currently
utilizes approximately 70% of production capability on a one-shift, five-day
basis. During 1998, the Company completed an expansion and improvement project
at its 26,300 square-foot Scotland facility. The Scotland facility currently
utilizes approximately 80% of available production capability on a one-shift,
five-day basis. Utilization is expected to drop to about 40% within several
months when full capacity and expected operating efficiencies from the 1998
expansion are brought fully online. Thus, the Company has substantial capacity
to expand production. The Company leases office and applications engineering lab
space in Kawasaki City, Japan to provide marketing and technical support for the
Japanese electronic chemical markets, and also leases an applications laboratory
in Phoenix, Arizona for the development of CMP products.
 
     The Company produces specialty chemicals manufactured to the specifications
and performance criteria of its customers ranging from gram to commercial
manufacturing quantities. These multifunctional manufacturing facilities enable
the Company to perform multi-step batch and continuous processing of specialties
and custom production of complex fine chemicals. The Company has versatile
facilities that use numerous reactors capable of producing custom fine chemicals
in quantities ranging from the very small amounts needed for initial product
testing, through pilot plant production of developmental quantities and
continuing through commercial production. Although historically customers have
purchased relatively small quantities of certain specialty chemicals, primarily
for their new product development and market testing, recently the sale of
commercial quantities of product has increased significantly as the trend to
outsource strengthens. Companies involved in the mass production of chemically
based agricultural, pharmaceutical and consumer products often find it expensive
and inefficient to manufacture small quantities of the complex chemicals
required for new product development or products with limited markets. By
providing a versatile array of manufacturing capabilities, related services and
capacity to a number of such companies, the Company achieves economies of scale
and is able to manufacture certain fine specialty chemicals more economically
and timely than they can be manufactured by its customers. As a result,
customers can reduce the time to market and capital exposure associated with the
manufacture and marketing of their new developmental products and are able to
better utilize and focus their own manufacturing capacity and research and
development abilities.
 
     The Company produces specialty and electronic chemicals at Tyrone,
Pennsylvania, Dayton, Ohio and Pascagoula, Mississippi. All of these facilities
are owned by the Company. Annual production capacity at the Tyrone facility is
between 4.5 million and 6.0 million pounds, depending on the product mix and the
type of processing required. Production in 1998 was approximately 6.0 million
pounds. During 1998, the Company completed an expansion at the Dayton facility
for the production of DUV photoresist resins. The Dayton facility also includes
a cGMP (current Good Manufacturing Practices) pilot plant for scale-up work and
production of small quantities of fine and pharmaceutical chemicals. Annual
production capacity at Dayton is between 1.5 million and 2.0 million pounds
depending on the product mix and the type of processing required. Production in
1998 was approximately 1.0 million pounds. Specialty chemical production
capacity at Pascagoula is between 70 million and 80 million pounds, depending on
the product mix and the processing
 
                                        5
<PAGE>   6
 
required. Production at this facility was approximately 61 million pounds during
1998. At these sites, the Company has differentiated itself by its capacity to
manufacture electronic and/or other specialty chemicals using multi-step batch
processing combined with the capability to produce specialty chemicals through
continuous process technology. In addition, the Company outsources the
manufacture of selected small volume chemicals.
 
  Marketing and Sales
 
     Electronic chemicals are marketed domestically and internationally in
Europe and the Pacific Rim. The California facility serves North America and the
Pacific Rim, and the Scotland facility serves the European community. These
chemicals are distributed in gallon, liter, returnable drum or large volume
dedicated containers. In Japan, the Company's electronic chemicals are
repackaged from bulk containers into returnable containers by the Company's
Japanese distributor. In late 1998, the Japanese distributor began toll
manufacturing select Company products for distribution in Japan. A majority of
the Company's electronic chemicals are sold through its internal sales force
although the Company utilizes independent sales representatives as well.
 
     The Company's other specialty chemicals are marketed globally. Most of
these chemicals are sold by purchase order or short-term agreements although the
Company has long-term contracts with a number of its largest customers. A
significant amount of these chemical sales are to three customers under
long-term contracts. These chemicals sales are made primarily through the
Company's internal sales force. Most of these specialty chemicals are sold in
drums. Exported product is shipped in ocean-going tankers, iso-containers or
drums to European, Japanese and South American markets. Domestic shipments are
typically by truck.
 
  Raw Materials
 
     The primary raw materials for the manufacture of electronic chemicals
include free-base hydroxylamine, diglycolamine, N-methylpyrrolidone and alumina
powders. With the exception of hydroxylamine, raw materials are generally
available in adequate quantities from several suppliers, subject to market
variation in price. Hydroxylamine is currently available from one supplier,
located in Japan. The Company is seeking an additional source of hydroxylamine
and is currently evaluating samples supplied by another manufacturer. The supply
of 4-hydroxyacetophenone, a primary raw material for the Company's acylation
derivatives business, is available from a single source under a long-term
contract.
 
     Primary raw materials for the production of its other specialty chemicals
include hydrogen, hydrogen peroxide, caustic, toluene, ethyl
trifluoroacetoacetate, 2-Fluorophenylhydrazine, o-aminophenol, formaldehyde,
ethanol and natural gas. These raw materials are obtained from a number of
different sources. The Company does not believe that any one source for raw
materials used in the production of these chemicals is material to the Company's
business.
 
  Competition
 
     The Company is one of the largest producers of post-metal cleaning
solutions for semiconductor production. Although there are approximately 12
companies participating in this market worldwide, only the Company and three
others have significant market share for advanced and post-metal cleaning
solutions required by the current state of the art semiconductor and related
industries. Competition is based on service, product performance, quality,
product development capabilities and cost of ownership. The Company has entered
into a cross-licensing agreement with a major competitor whereby the Company
licenses its HDA(TM) (hydroxylamine) patented etch residue remover technology.
The agreement results from a patent infringement complaint brought by the
Company against the competitor in federal court. The agreement allows the
competitor to continue to market its products which utilize the Company's
hydroxylamine technology, but provides for the Company to receive a royalty and
license fee. The Company has approximately five U.S. and four foreign patents
regarding its HDA(TM) technology. The earliest of these patents expires in 2011.
Regarding CMP, the oxide slurry market is dominated by two other companies, with
the larger company holding a 90%
 
                                        6
<PAGE>   7
 
market share. In the tungsten slurry market, the Company is now the third
largest supplier for this application. The Company is one of the largest
suppliers of products to the global DUV photoresist resin market.
 
     The Company competes domestically and internationally with numerous
producers of specialty chemicals. Major competitors are both smaller and larger
companies. Competition is fierce and is based on service, quality, manufacturing
capabilities and expertise in batch chemical production, research and
development capabilities and price. The Company's large batch manufacturing
sites allow it the flexibility and breadth of service to meet a wide variety of
customer needs, including the ability to provide gram and multi-ton quantities
in either cGMP (current Good Manufacturing Practices) or ISO-9000 manufacturing
environments.
 
  Seasonality of Business
 
     Generally, electronic and other specialty chemical sales are not seasonal
and working capital requirements do not vary significantly from period to
period.
 
POLYURETHANE CHEMICALS
 
  General
 
     The Company produces aniline and nitrobenzene by a continuous production
process at its facilities in Pascagoula, Mississippi and Baytown, Texas. Unlike
electronic and other specialty chemicals, these chemicals generally require
additional processing steps and chemical reactions to produce the end product
used by consumers and are primarily sold under long-term contracts.
 
     Typically, polyurethane chemicals are more sensitive to the business cycle
and the cost of raw materials than are most electronic and specialty chemicals,
although the Company's sales contracts provide protection from fluctuation in
raw material price for most of the aniline sold. These chemicals are typically
sold in large volumes to industrial customers that purchase on the basis of
product specifications. The key to successful production of these chemicals is
efficient chemical conversion of large quantities of raw materials and
productive use of plant capacity. Providing technical services to customers is
generally less important than for specialty products.
 
     The Company's manufacturing facility in Pascagoula is supported by storage,
rail, truck, barge and ship distribution facilities. The Pascagoula facility
utilizes nitration technology and a proprietary process for continuous
hydrogenation. The annual polyurethane chemical production capacity at the
facility is between 315 million and 350 million pounds depending on the products
being produced. Production of polyurethane chemicals at the Pascagoula facility
during 1998 was approximately 335 million pounds, which was lower than planned
because of production problems during the first half of the year and a hurricane
during the third quarter.
 
     In 1996, the Company entered into a long-term agreement with Bayer
Corporation ("Bayer") to build, own and operate a world scale nitrobenzene and
aniline facility at Bayer's Baytown, Texas chemical complex to supply Bayer's
MDI (methylene diphenyl diisocyantate) manufacturing operations. Phase I of the
facility, with a design capacity of 250 million pounds, was completed in 1998
and is now operating near design capacity. If a potential Phase II to the
facility is constructed, it would add another 250 million pounds of capacity. A
majority of the Company's current aniline production from the Pascagoula
facility is sold to Bayer under a long-term contract. If Phase II of the Baytown
facility is constructed, Bayer may terminate this contract and take requirements
from the Baytown facility.
 
     Aniline is the Company's largest volume product. The Company is among the
largest merchant marketers of aniline in the U.S. Most of the aniline produced
in the U.S. is used to manufacture MDI. MDI's primary end-use is in rigid
polyurethane foam, an insulation material that is widely used in residential and
commercial construction. MDI is also used in the manufacture of impact-resistant
plastic that is used as a replacement for metal in automobile parts such as
bumpers, where flexibility and impact resistance are important. Aniline's other
primary applications are in the production of an antioxidizing (anti-cracking)
agent used in the manufacture of synthetic rubber and in a widely used herbicide
for corn and soybeans.
 
                                        7
<PAGE>   8
 
Polyurethane chemicals accounted for approximately 41%, 40% and 39% of the
Company's consolidated sales for 1998, 1997 and 1996, respectively.
 
     Nitrobenzene is used to make aniline and is also sold separately for the
manufacture of pharmaceuticals, rubber and agricultural chemicals.
 
  Marketing and Sales
 
     The Company's polyurethane chemicals are sold primarily in the U.S. Most
chemicals produced in this segment are sold under long-term contracts to a
number of customers. The Company's internal sales force accounts for essentially
all of the sales in this segment. These products are generally sold in bulk.
Domestic shipments are by barge, rail or tank trucks and exports are shipped in
ocean-going tankers, iso-containers or drums.
 
  Raw Materials
 
     Benzene, which is a principal raw material for polyurethane chemicals
production, is a readily available commodity by-product of oil refining. Like
most commodities, the price of benzene is subject to fluctuation. Benzene prices
are affected by the demand for a variety of products, principally including
styrene and phenolic resins. The Company is protected from fluctuations in raw
material prices under the contracts in which most of its aniline production is
sold. The remainder of its production is sold under short-term contracts or
purchase orders at prices that generally reflect its actual raw material cost.
Other significant raw materials include ammonia and natural gas. The Company
purchases ammonia at market prices. The Company purchases natural gas in the
spot market for use in producing the hydrogen necessary for its manufacturing
processes. This gas is transported into the Pascagoula plant through an
interstate pipeline. Prices paid by the Company for natural gas are affected by
the degree of interruptibility of the gas supply.
 
  Competition
 
     The Company is one of five major U.S. producers of aniline, with
approximately 25% of domestic capacity and an estimated 7.5% of world capacity.
Major competitors are large chemical companies. Competition for the products
produced in this segment is based on price, service, quality, marketing and
research and development support capabilities.
 
  Seasonality of Business
 
     Generally, the Company's polyurethane chemical sales are not seasonal and
working capital requirements do not vary significantly from period to period.
 
COMPANY RESEARCH AND DEVELOPMENT
 
     The Company conducts research and development to improve existing products,
to develop and produce new specialty and performance chemicals and to develop
and improve production processes. The Company spent approximately $10.7 million,
$5.3 million and $5.8 million on research and development in 1998, 1997 and
1996, respectively. Research facilities include laboratories, pilot plant and
semi-works for process research and development with gram to multi-pound sample
production capabilities. The Company maintains a radiation curing applications
laboratory in Pascagoula to evaluate new products and provide customer technical
support. The Company's electronic chemicals applications engineering and
research and development labs in California, Texas, Scotland and Japan are
strategically located near key regional semiconductor production centers,
enabling applications engineers to work closely with customers to develop unique
chemical solutions to semiconductor manufacturing needs and to test
developmental products. The Company continues to focus research efforts on
developing new and improved electronic chemicals, including remover products,
CMP and DUV resins. The Company also sponsors applied research at leading
universities in the U.S. and the U.K. These closely directed programs have led
to the development and introduction of proprietary technology in electronic and
other specialty chemicals. In addition, the Company has entered into a joint
development
 
                                        8

arrangement with an industry consortium to develop advanced products to meet
future semiconductor manufacturing technology.
 
COMPANY PATENTS
 
     The Company owns, or is licensed under, a number of patents, patent
applications and trade secrets covering its products and processes. The Company
believes that, in the aggregate, the rights under such patents and licenses are
important to its operations, but, with the exception of the HDA(TM) etch residue
remover patents referenced above, does not consider any patent, or license, or
group thereof related to a specific process or product, to be of material
importance when viewed from the standpoint of the Company's total business.
 
ENVIRONMENTAL CONSIDERATIONS
 
     Company operations are subject to a wide variety of environmental laws and
regulations governing emissions to the air, discharges to water sources, and the
handling, storage, treatment and disposal of waste materials, as well as other
laws and regulations concerning health and safety conditions. The Company holds
a number of environmental permits and licenses regulating air emissions, water
discharges and hazardous waste disposal and, to the best of its knowledge, is in
material compliance with such requirements at all locations. The Company makes
capital and other expenditures in a continuing effort to comply with
environmental laws and regulations, or changing interpretations of existing laws
and regulations. The Company's environmental capital expenditures for 1998 were
$0.2 million. Projected environmental capital expenditures for 1999 and 2000 are
$1.4 million and $1.1 million, respectively. While these expenditures are
necessary to comply with environmental laws and regulations, they may also
reduce operating expenses and improve efficiencies.
 
     The Company monitors and participates in the environmental regulatory
development process which assists it in evaluating new laws and regulations. The
Company does not anticipate a material increase in expenses related to current
environmental regulations, but because federal and state environmental laws and
regulations are constantly changing, the Company is unable to predict their
future impact.
 
     The Company has received notices from the U.S. Environmental Protection
Agency or similar state agencies that it has been deemed a potentially
responsible party ("PRP") under Superfund or a comparable state statute at
several sites and, thus, may be liable for a share of the associated remediation
cost. It is difficult to estimate the Company's ultimate liability relating to
these sites due to several uncertainties such as, but not limited to, the method
and extent of remediation, the percentage of material attributable to the
Company at the site relative to that attributable to other parties, and the
financial capabilities of the other PRPs. Based on currently available
information, however, the Company does not believe that its future liability at
these sites will be material to its financial condition, results of operations,
cash flow or competitive position.
 
DISCONTINUED OPERATIONS
 
     Following is a brief discussion of the Engineered Products and Services
business and the Steel business, both of which are reported as discontinued
operations in anticipation of being divested.
 
ENGINEERED PRODUCTS AND SERVICES
 
     The Company has announced plans to dispose of the Engineered Products and
Services business and it has been classified as a discontinued operation. The
Company anticipates that the disposition should be completed during 1999. This
business principally includes the development and marketing of proprietary
equipment and systems for industrial applications. These include design and
production of low-emission burners, flares, incinerators and thermal plasma
equipment. Raw materials and components for these operations are available from
numerous vendors. The businesses are not considered materially seasonal. This
business is operated primarily through the Company's subsidiary Callidus
Technologies Inc.
 
     Principal products and services are custom designed and fabricated
gas/liquid incinerators, flares, solid waste systems, vapor recovery units,
burners and thermal plasma heating systems. The Company also provides
engineering and consulting services for environmental and combustion
applications.
 
                                        9
<PAGE>   10
 
     The Company markets these products and services worldwide to refining,
petrochemical, chemical, pharmaceutical, wood products and other industries
requiring disposal of gas, liquid and solid wastes. Marketing is primarily
through a combination of manufacturers' representatives and company personnel.
The market is well established but growing through advancements of existing
technology, driven primarily by increasingly strict environmental regulations
both in the U.S. and abroad. Competition is based on a wide variety of factors,
with the most prominent being price, technological innovation and delivery
schedule. The Company competes with the John Zink Company, which has a
significant share of the burner, flare and vapor recovery markets. Numerous
competitors exist in the gas and liquids incineration market. Primary
competition in the solid waste systems market comes from alternative
technologies. The Company is affected by a variety of factors beyond its
control, including governmental control of environmental standards and
compliance deadlines, competitor pricing strategies and changing technology; any
one of which could impact operating results. The Company leases office space in
Tulsa, Oklahoma, owns a manufacturing and test facility in Beggs, Oklahoma and
has leased foreign offices in Belgium, England, France, Germany and Japan.
 
STEEL
 
     The Company's Steel business is operated through its subsidiary, FirstMiss
Steel, Inc. This operation is conducted through a 400,000 square-foot steel
melting and production facility in Hollsopple, Pennsylvania, which is
approximately 100 miles east of Pittsburgh. As previously noted, the Company
plans to divest the steel business. These efforts have been hampered by adverse
industry conditions. The Company leases the land on which the facility is
located but has the right to purchase the land for a nominal price at the
conclusion of the lease. Annual capacity of the operation includes 150,000 tons
of carbon, alloy and specialty grade, bottom-poured ingots and 50,000 tons of
high-grade steel billets through a horizontal continuous caster. The value-
added product line includes specialty stainless and tool steel ingots or
billets, which are converted into forged billets, bars and plates by outside
processors. Small quantities of cobalt, nickel, copper and iron-based alloys in
bars and wire are also produced from two small horizontal continuous casters,
small bottom-poured forging ingots and remelt sand ingots. There is an adequate
supply in the North American market of steel scrap and various alloys for raw
material use.
 
     Carbon and alloy steel ingots are sold directly to the forging industry,
ring rollers, extruders and integrated steel producers. The Company competes
primarily with three other steel companies in this market. Specialty steel
products are primarily sold to steel service centers and forgers. Ten customers
account for approximately 60% of the Company's steel revenue. Alloy products are
sold as feedstock directly to forgers, extruders and investment casters. There
are numerous competitors, both domestic and foreign, that compete with the
Company in the specialty steel, ferrous and nonferrous metals markets.
Competitive factors include price, quality and service. Carbon steel ingots and
billets are commodities and are extremely price competitive. Stainless and tool
steel long product pricing is currently being pressured by strong import
penetration.
 
ITEM 2. PROPERTIES
 
     A description of various properties and the segments to which they relate
is included in the Business discussion located on pages 4 through 10 of this

TO THE PURCHASERS LISTED IN THE ATTACHED SCHEDULE A:

Ladies and Gentlemen:

         CHEMFIRST INC., a Mississippi corporation (the "Company"), agrees with
the Purchasers named on Schedule A (the "Purchasers") to this Note Purchaser
Agreement (this or the "Agreement") as follows:

SECTION 1.           AUTHORIZATION OF NOTES.

         The Company will authorize the issue and sale of (i) $15,000,000
aggregate principal amount of its 6.50% Series 1998-A Senior Notes, Tranche A,
due October 30, 2003 (the "Tranche A Notes"), (ii) $5,000,000 aggregate
principal amount of its 6.75% Series 1998-A Senior Notes, Tranche B, due October
30, 2005 (the "Tranche B Notes", and together with the Tranche A Notes, the
"Series A Notes"). The Series A Notes together with each Series of Additional
Notes which may from time to time be issued pursuant to the provisions of
Section 2.2 are collectively referred to as the "Notes" (such term shall also
include any such notes issued in substitution therefor pursuant to Section 13 of
this Agreement or the Other Agreements (as hereinafter defined)). The Tranche A
Notes and the Tranche B Notes shall be substantially in the forms set out in
Exhibits 1 and 2, respectively, with such changes therefrom, if any, as may be
approved by you and the Company. Certain capitalized terms used in this
Agreement are defined in Schedule B; references to a "Schedule" or an "Exhibit"
are, unless otherwise specified, to a Schedule or an Exhibit attached to this
Agreement.

SECTION 2.           SALE AND PURCHASE OF NOTES.

         Section 2.1. Series A Notes. Subject to the terms and conditions of
this Agreement, the Company will issue and sell to the Purchasers and the
Purchasers will purchase from the Company, at the Closing provided for in
Section 3, Series A Notes of the Tranche and in the principal amount specified
opposite such Purchaser's name in Schedule A at the purchase price of 100% of
the principal amount thereof. The Purchasers' obligation hereunder, and the
obligations of the Additional Purchasers under the Supplements, are several and
not joint obligations, and the Purchasers shall have no obligation under any
Supplement and no liability to any Person for the performance or nonperformance
by any Additional Purchaser thereunder.

         Section 2.2. Additional Series of Notes. The Company may, from time to
time, in its sole discretion but subject to the terms hereof, issue and sell one
or more additional Series of its unsecured promissory notes under the provisions
of this Agreement pursuant to a supplement (a "Supplement") substantially in
the form of Exhibit S. Each additional Series of Notes (the "Additional Notes")
issued pursuant to a Supplement shall be subject to the following terms and
conditions:

                   (i) each Series of Additional Notes, when so issued, shall be
         differentiated from all previous series by sequential alphabetical
         designation inscribed thereon;

                  (ii) Additional Notes of the same Series may consist of more
         than one different and separate tranches and may differ with respect to
         outstanding principal amounts, maturity dates, interest rates and
         premiums, if any, and price and terms of redemption or payment prior to
         maturity, but all such different and separate tranches of the same
         Series shall vote as a single class and constitute one Series;

                 (iii) each Series of Additional Notes shall be dated the date
         of issue, bear interest at such rate or rates, mature on such date or
         dates, be subject to such mandatory and optional prepayment on the
         dates and at the premiums, if any, have such additional or different
         conditions precedent to closing, such representations and warranties
         and such additional covenants as shall be specified in the Supplement
         under which such Additional Notes are issued, provided, that any such
         additional covenants shall inure to the benefit of all holders of Notes
         so long as any Additional Notes issued pursuant to such Supplement
         remain outstanding;

                  (iv) each Series of Additional Notes issued under this
         Agreement shall be in substantially the form of Exhibit 1 to Exhibit S
         hereto with such variations, omissions and insertions as are necessary
         or permitted hereunder;

                   (v) the minimum principal amount of any Note issued under a
         Supplement shall be $100,000, except as may be necessary to evidence
         the outstanding amount of any Note originally issued in a denomination
         of $100,000 or more;

                  (vi) all Additional Notes shall constitute Senior Debt of the
         Company and shall rank pari passu with all other outstanding Notes; and

                 (vii) no Additional Notes shall be issued hereunder if at the
         time of issuance thereof and after giving effect to the application of
         the proceeds thereof, any Default or Event of Default shall have
         occurred and be continuing.

SECTION 3.           CLOSING.

         The sale and purchase of the Series A Notes to be purchased by the
Purchasers shall occur at the offices of Chapman and Cutler, 111 West Monroe
Street, Chicago, Illinois 60603, at 11:00 A.M. Chicago time, at a closing (the
"Closing") on November 10, 1998 or on such other Business Day thereafter on or
prior to November 15, 1998 as may be agreed upon by the 

                                      -2-

Company and the Purchasers. At the Closing, the Company will deliver to each
Purchaser the Notes to be purchased by such Purchaser in the form of a single
Note (or such greater number of Notes in denominations of at least $100,000 as
such Purchaser may request) dated the date of the Closing and registered in such
Purchaser's name (or in the name of such Purchaser's nominee), against delivery
by such Purchaser to the Company or its order of immediately available funds in
the amount of the purchase price therefor by wire transfer of immediately
available funds for the benefit of the Company to its account at Bank of America
National Trust and Savings Association, Account No. 8188300511 (ABA #071000039).
If, at the Closing, the Company shall fail to tender such Notes to any Purchaser
as provided above in this Section 3, or any of the conditions specified in
Section 4 shall not have been fulfilled to any Purchaser's satisfaction, such
Purchaser shall, at its election, be relieved of all further obligations under
this Agreement, without thereby waiving any rights such Purchaser may have by
reason of such failure or such nonfulfillment.

SECTION 4.           CONDITIONS TO CLOSING.

         The obligation of each Purchaser to purchase and pay for the Notes to
be sold to such Purchaser at the Closing is subject to the fulfillment to such
Purchaser's satisfaction, prior to or at the Closing, of the following
conditions:

         Section 4.1. Representations and Warranties. The representations and
warranties of the Company in this Agreement shall be correct when made and at
the time of the Closing.

         Section 4.2. Performance; No Default. The Company shall have performed

         The Company represents and warrants to each Purchaser that:

         Section 5.1. Organization; Power and Authority. The Company is a
corporation duly organized, validly existing and in good standing under the laws
of its jurisdiction of incorporation, and is duly qualified as a foreign
corporation and is in good standing in each jurisdiction in which such
qualification is required by law, other than those jurisdictions as to which the
failure to be so qualified or in good standing could not, individually or in the

has the corporate power and authority to own or hold under lease the properties
it purports to own or hold under lease, to transact the business it transacts
and proposes to transact, to execute and deliver this Agreement and the Series A
Notes and to perform the provisions hereof and thereof.

         Section 5.2. Authorization, etc. This Agreement and the Series A Notes
have been duly authorized by all necessary corporate action on the part of the
Company and this Agreement constitutes, and upon execution and delivery thereof
each Note will constitute, a legal, valid and binding obligation of the Company
enforceable against the Company in accordance with its terms, except as such
enforceability may be limited by (i) applicable bankruptcy, insolvency,
reorganization, moratorium or other similar laws affecting the enforcement of
creditors' rights generally and (ii) general principles of equity (regardless of
whether such enforceability is considered in a proceeding in equity or at law).

         Section 5.3. Disclosure. The Company, through its agents, NationsBanc
Montgomery Securities and ABN AMRO Incorporated, has delivered to each Purchaser
a copy of a Private

Placement Memorandum, dated August, 1998 (the "Memorandum"), relating to the
transactions contemplated hereby. The Memorandum fairly describes, in all
material respects, the general nature of the business and principal properties
of the Company and its Restricted Subsidiaries. This Agreement, the Memorandum,
the documents, certificates or other writings delivered to the Purchasers by or
on behalf of the Company in connection with the transactions contemplated hereby
and the financial statements listed in Schedule 5.5, taken as a whole, do not
contain any untrue statement of a material fact or omit to state any material
fact necessary to make the statements therein not misleading in light of the
circumstances under which they were made. Since June 30, 1998, there has been no
change in the financial condition, operations, business or properties of the
Company or any Restricted Subsidiary except changes that individually or in the
aggregate could not reasonably be expected to have a Material Adverse Effect.
There is no fact known to the Company that could reasonably be expected to have
a Material Adverse Effect that has not been set forth herein or in the
Memorandum or in the other documents, certificates and other writings for the
Company (including the Press Release dated October 22, 1998 relating to the
earnings of the Company for the Fiscal Period ending September 30, 1998
delivered to the Purchasers by or on behalf of the Company specifically for use
in connection with the transactions contemplated hereby.

         Section 5.4. Organization and Ownership of Shares of Restricted
Subsidiaries; Affiliates and Investments. (a) Schedule 5.4 contains (except as
noted therein) complete and correct lists (i) of the Company's Restricted and
Unrestricted Subsidiaries, and showing, as to each Subsidiary, the correct name
thereof, the jurisdiction of its organization, and the percentage of shares of
each class of its capital stock or similar equity interests outstanding owned by
the Company and each other Subsidiary, (ii) of the Company's Affiliates, other
than Unrestricted Subsidiaries, (iii) of the Company's directors and executive
officers and (iv) the Investments existing at the Closing, other than
Investments in Subsidiaries and Affiliates.

         (b) All of the outstanding shares of capital stock or similar equity
interests of each Subsidiary shown in Schedule 5.4 as being owned by the Company
and its Subsidiaries have been validly issued, are fully paid and nonassessable
and are owned by the Company or another Subsidiary free and clear of any Lien
(except as otherwise disclosed in Schedule 5.4).

         (c) Each Subsidiary identified in Schedule 5.4 is a corporation or
other legal entity duly organized, validly existing and in good standing under
the laws of its jurisdiction of organization, and is duly qualified as a foreign
corporation or other legal entity and is in good standing in each jurisdiction
in which such qualification is required by law, other than those jurisdictions
as to which the failure to be so qualified or in good standing could not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect. Each such Subsidiary has the corporate or other power and
authority to own or hold under lease the properties it purports to own or hold
under lease and to transact the business it transacts and proposes to transact.

         (d) No Subsidiary is a party to, or otherwise subject to, any legal
restriction or any agreement (other than customary limitations imposed by
corporate law statutes) restricting the ability of such Subsidiary to pay
dividends out of profits or make any other similar distributions of profits to
the Company or any of its Subsidiaries that owns outstanding shares of capital
stock or similar equity interests of such Subsidiary.

         Section 5.5. Financial Statements. The Company has delivered to each
Purchaser copies of the financial statements of the Company and its Subsidiaries
listed on Schedule 5.5. All of said financial statements (including in each case
the related schedules and notes) fairly present in all material respects the
consolidated financial position of the Company and its Subsidiaries as of the
respective dates specified in such financial statements and the consolidated
results of their operations and cash flows for the respective periods so
specified and have been prepared in accordance with GAAP consistently applied
throughout the periods involved except as set forth in the notes thereto
(subject, in the case of any interim financial statements, to normal, recurring
year-end adjustments).

         Section 5.6. Compliance with Laws, Other Instruments, etc. The
execution, delivery and performance by the Company of this Agreement and the
Series A Notes will not (a) contravene, result in any breach of, or constitute a
default under, or result in the creation of any Lien in respect of any property
of the Company or any Restricted Subsidiary under, any indenture, mortgage, deed
of trust, loan, purchase or credit agreement, lease, corporate charter or
by-laws, or any other agreement or instrument to which the Company or any
Restricted Subsidiary is bound or by which the Company or any Restricted
Subsidiary or any of their respective properties may be bound or affected, (b)
conflict with or result in a breach of any of the terms, conditions or
provisions of any order, judgment, decree, or ruling of any court, arbitrator or
Governmental Authority applicable to the Company or any Restricted Subsidiary or
(c) violate any provision of any statute or other rule or regulation of any
Governmental Authority applicable to the Company or any Restricted Subsidiary
which could reasonably be expected to have a Material Adverse Effect.

         Section 5.7. Governmental Authorizations, etc. No consent, approval or
authorization of, or registration, filing or declaration with, any Governmental
Authority is required in connection with the execution, delivery or performance
by the Company of this Agreement or the Series A Notes.

         Section 5.8. Litigation; Observance of Agreements, Statutes and Orders.
(a) There are no actions, suits or proceedings pending or, to the knowledge of
the Company, threatened against or affecting the Company or any Subsidiary or
any property of the Company or any Subsidiary in any court or before any
arbitrator of any kind or before or by any Governmental Authority that,
individually or in the aggregate, could reasonably be expected to have a
Material Adverse Effect.

         (b) Neither the Company nor any Subsidiary is in default under any term
of any agreement or instrument to which it is a party or by which it is bound,
or any order, judgment, decree or ruling of any court, arbitrator or
Governmental Authority or is in violation of any applicable law, ordinance, rule
or regulation (including without limitation Environmental Laws) of any
Governmental Authority, which default or violation, individually or in the
aggregate, could reasonably be expected to have a Material Adverse Effect.

         Section 5.9. Taxes. The Company and its Subsidiaries have filed all tax
returns that are required to have been filed in any jurisdiction, and have paid
all taxes shown to be due and payable on such returns and all other taxes and
assessments levied upon them or their properties, assets, income or franchises,
to the extent such taxes and assessments have become due and 



                                      -7-

<PAGE>   13


payable and before they have become delinquent, except for any taxes and
assessments (a) the amount of which is not individually or in the aggregate
Material or (b) the amount, applicability or validity of which is currently
being contested in good faith by appropriate proceedings and with respect to
which the Company or a Subsidiary, as the case may be, has established adequate
reserves in accordance with GAAP. The Company knows of no basis for any other
tax or assessment that could reasonably be expected to have a Material Adverse
Effect. The charges, accruals and reserves on the books of the Company and its
Subsidiaries in respect of Federal, state or other taxes for all fiscal periods
are adequate. The Federal income tax liabilities of the Company and its
Subsidiaries have been determined by the Internal Revenue Service and paid for
all fiscal years up to and including the fiscal year ended June 30, 1988.

        Section 5.10. Title to Property; Leases. The Company and its
Subsidiaries have good and sufficient title to their respective properties which
the Company and its Subsidiaries own or purport to own that individually or in
the aggregate are Material, including all such properties reflected in the most
recent audited balance sheet referred to in Section 5.5 or purported to have
been acquired by the Company or any Restricted Subsidiary after said date
(except as sold or otherwise disposed of in the ordinary course of business), in
each case free and clear of Liens prohibited by this Agreement. All leases that
individually or in the aggregate are Material are valid and subsisting and are
in full force and effect in all material respects.

         Section 5.11. Licenses, Permits, etc. Except as disclosed in Schedule
5.11,

         (a) the Company and its Restricted Subsidiaries own or possess all
licenses, permits, franchises, authorizations, patents, copyrights, service
marks, trademarks and trade names, or rights thereto, that individually or in
the aggregate are Material, without known conflict with the rights of others;

         (b) to the best knowledge of the Company, no product of the Company or
any Restricted Subsidiary infringes in any Material respect any license, permit,
franchise, authorization, patent, copyright, service mark, trademark, trade name
or other right owned by any other Person; and

         (c) to the best knowledge of the Company, there is no Material
violation by any Person of any right of the Company or any of its Restricted
Subsidiaries with respect to any patent, copyright, service mark, trademark,
trade name or other right owned or used by the Company or any of its Restricted
Subsidiaries.

        Section 5.12. Compliance with ERISA. (a) The Company and each ERISA
Affiliate have operated and administered each Plan in compliance with all
applicable laws except for such instances of noncompliance as have not resulted
in and could not reasonably be expected to result in a Material Adverse Effect.
Neither the Company nor any ERISA Affiliate has incurred any liability pursuant
to Title I or IV of ERISA or the penalty or excise tax provisions of the Code
relating to employee benefit plans (as defined in Section 3 of ERISA), and no
event, transaction or condition has occurred or exists that could reasonably be
expected to result in the incurrence of any such liability by the Company or any
ERISA Affiliate, or in the imposition of any Lien on any of the rights,
properties or assets of the Company or any ERISA Affiliate, in 









                                      -8-
<PAGE>   14



either case pursuant to Title I or IV of ERISA or to such penalty or excise tax
provisions or to Section 401(a)(29) or 412 of the Code, other than such
liabilities or Liens as would not be individually or in the aggregate Material.

         (b) The present value of the aggregate benefit liabilities under each
of the Plans (other than Multiemployer Plans), determined as of the end of such
Plan's most recently ended plan year on the basis of the actuarial assumptions
specified for funding purposes in such Plan's most recent actuarial valuation
report, did not exceed the aggregate current value of the assets of such Plan
allocable to such benefit liabilities, or such deficit, if any, did not exceed
5% of Consolidated Net Worth. The terms "benefit liabilities" has the meaning
specified in section 4001 of ERISA and the terms "current value" and "present
value" have the meaning specified in section 3 of ERISA.

         (c) The Company and its ERISA Affiliates have not incurred withdrawal
liabilities (and are not subject to contingent withdrawal liabilities) under
section 4201 or 4204 of ERISA in respect of Multiemployer Plans that
individually or in the aggregate are Material.

         (d) The expected post-retirement benefit obligation (determined as of
the last day of the Company's most recently ended fiscal year in accordance with
Financial Accounting Standards Board Statement No. 106, without regard to
liabilities attributable to continuation coverage mandated by section 4980B of
the Code) of the Company and its Restricted Subsidiaries is not Material or has
otherwise been disclosed in the most recent audited consolidated financial
statements of the Company and its Subsidiaries.

         (e) The execution and delivery of this Agreement and the issuance and
sale of the Notes hereunder will not involve any transaction that is subject to
the prohibitions of section 406 of ERISA or in connection with which a tax could
be imposed pursuant to section 4975(c)(1)(A)-(D) of the Code. The representation
by the Company in the first sentence of this Section 5.12(e) is made in reliance
upon and subject to the accuracy of each Purchaser's representation in Section
6.2 as to the sources of the funds used to pay the purchase price of the Notes
to be purchased by such Purchaser.

        Section 5.13. Private Offering by the Company. Neither the Company nor
anyone acting on its behalf has offered the Series A Notes or any similar
securities for sale to, or solicited any offer to buy any of the same from, or
otherwise approached or negotiated in respect thereof with, any Person other
than the Purchasers and not more than 60 other Institutional Investors, each of
which has been offered the Series A Notes at a private sale for investment.
Neither the Company nor anyone acting on its behalf has taken, or will take, any
action that would subject the issuance or sale of the Series A Notes to the
registration requirements of Section 5 of the Securities Act.

        Section 5.14. Use of Proceeds; Margin Regulations. The Company will
apply the proceeds of the sale of the Series A Notes to repay outstanding
indebtedness, repurchase shares of capital stock of the Company and for general
corporate purposes. No part of the proceeds from the sale of the Series A Notes
hereunder will be used, directly or indirectly, for the purpose of buying or
carrying any margin stock within the meaning of Regulation U of the Board of
Governors of the Federal Reserve System (12 CFR 207), or for the purpose of
buying or carrying 





                                      -9-
<PAGE>   15


or trading in any securities under such circumstances as to involve the Company
in a violation of Regulation X of said Board (12 CFR 224) or to involve any
broker or dealer in a violation of Regulation T of said Board (12 CFR 220).
Margin stock does not constitute more than 5% of the value of the consolidated
assets of the Company and its Subsidiaries and the Company does not have any
present intention that margin stock will constitute more than 5% of the value of
such assets. As used in this Section, the terms "margin stock" and "purpose of
buying or carrying" shall have the meanings assigned to them in said Regulation
U.

        Section 5.15. Existing Debt; Future Liens. (a) Except as described
therein, Schedule 5.15 sets forth a complete and correct list of all outstanding
Debt of the Company and its Restricted Subsidiaries as of June 30, 1998, since
which date there has been no Material change in the amounts, interest rates,
sinking funds, installment payments or maturities of the Debt of the Company or
its Restricted Subsidiaries. Neither the Company nor any Restricted Subsidiary
is in default and no waiver of default is currently in effect, in the payment of
any principal or interest on any Debt of the Company or such Restricted
Subsidiary and no event or condition exists with respect to any Debt of the
Company or any Restricted Subsidiary (exceeding such amount) that would permit
(or that with notice or the lapse of time, or both, would permit) one or more
Persons to cause such Debt to become due and payable before its stated maturity
or before its regularly scheduled dates of payment.

         (b) Neither the Company nor any Restricted Subsidiary has agreed or
consented to cause or permit in the future (upon the happening of a contingency
or otherwise) any of its property, whether now owned or hereafter acquired, to
be subject to a Lien not permitted by Section 10.5.

        Section 5.16. Foreign Assets Control Regulations, etc. Neither the sale
of the Series A Notes by the Company hereunder nor its use of the proceeds
thereof will violate the Trading with the Enemy Act, as amended, or any of the
foreign assets control regulations of the United States Treasury Department (31
CFR, Subtitle B, Chapter V, as amended) or any enabling legislation or executive
order relating thereto.

        Section 5.17. Status under Certain Statutes. Neither the Company nor any
Subsidiary is an "investment company" registered or required to be registered
under the Investment Company Act of 1940, as amended, or is subject to
regulation under the Public Utility Holding Company Act of 1935, as amended, the
ICC Termination Act of 1995 or the Federal Power Act, as amended.

        Section 5.18. Environmental Matters. Neither the Company nor any
Restricted Subsidiary has knowledge of any claim or has received any notice of
any claim, and no proceeding has been instituted asserting any claim against the
Company or any of its Restricted Subsidiaries or any of their respective real
properties now owned, leased or operated by any of them or other assets, and
neither the Company nor any Restricted Subsidiary has any knowledge of any
proceeding which has been instituted asserting any claim against the Company or
any of its Restricted Subsidiaries for any real properties formerly owned,
leased or operated by any them, alleging any damage to the environment or
violation of any Environmental Laws, except, 






                                      -10-
<PAGE>   16



in each case, such as could not reasonably be expected to result in a Material
Adverse Effect. Except as otherwise disclosed to the Purchasers in writing:

                   (a) neither the Company nor any Restricted Subsidiary has
         knowledge of any facts which would give rise to any claim, public or
         private, of violation of Environmental Laws or damage to the
         environment emanating from, occurring on or in any way related to real
         properties now or formerly owned, leased or operated by any of them or
         to other assets or their use, except, in each case, such as could not
         reasonably be expected to result in a Material Adverse Effect;

                   (b) neither the Company nor any of its Restricted
         Subsidiaries has stored any Hazardous Materials on real properties now
         or formerly owned, leased or operated by any of them and or has
         disposed of any Hazardous Materials in a manner contrary to any
         Environmental Laws in each case in any manner that could reasonably be
         expected to result in a Material Adverse Effect; and

                   (c) all buildings on all real properties now owned, leased or
         operated by the Company or any of its Restricted Subsidiaries are in
         compliance with applicable Environmental Laws, except where failure to
         comply could not reasonably be expected to result in a Material Adverse
         Effect.

         Section 5.19. Computer 2000 Compliant. The Company and its Restricted
Subsidiaries have implemented measures to have all critical business and
computer systems year 2000 compliant in a timely manner and the advent of the
year 2000 and its impact on said internal business and computer systems are not
expected to have a Material Adverse Effect.

SECTION 6.           REPRESENTATIONS OF THE PURCHASER.

         Section 6.1. Purchase for Investment. Each Purchaser represents that
such Purchaser is purchasing the Series A Notes for its own account or for one
or more separate accounts maintained by it or for the account of one or more
pension or trust funds and not with a view to the distribution thereof, provided
that the disposition of its or their property shall at all times be within its
or their control. Each Purchaser understands that the Series A Notes have not
been registered under the Securities Act and may be resold only if registered
pursuant to the provisions of the Securities Act or if an exemption from
registration is available, except under circumstances where neither such
registration nor such an exemption is required by law, and that the Company is
not required to register the Series A Notes.

         Section 6.2. Source of Funds. Each Purchaser represents that at least
one of the following statements is an accurate representation as to each source
of funds (a "Source") to be used by such Purchaser to pay the purchase price of
the Series A Notes to be purchased by such Purchaser hereunder:

                   (a) if such Purchaser is an insurance company, the Source is
         an "insurance company general account" within the meaning of Department
         of Labor Prohibited Transaction Exemption 95-60 (issued July 12, 1995)

         plan" (within the meaning of Section 3(3) of ERISA or Section
         4975(e)(1) of the Code), treating as a single plan, all plans
         maintained by the same employer or employee organization, with respect
         to which the amount of the general account reserves and liabilities for
         all contracts held by or on behalf of such plan, exceed ten percent
         (10%) of the total reserves and liabilities of such general account
         (exclusive of separate account liabilities) plus surplus, as set forth
         in the NAIC Annual Statement filed with your such Purchaser's state of
         domicile; or

                   (b) the Source is either (i) an insurance company pooled
         separate account, within the meaning of Prohibited Transaction
         Exemption ("PTE") 90-1 (issued January 29, 1990), or (ii) a bank
         collective investment fund, within the meaning of the PTE 91-38 (issued
         July 12, 1991) and, except as such Purchaser has disclosed to the
         Company in writing pursuant to this paragraph (b), no employee benefit
         plan or group of plans maintained by the same employer or employee

SECTION 8.           PREPAYMENT OF THE SERIES A NOTES.

         Section 8.1. Required Prepayments. There shall be no principal
prepayments on any Tranche of the Series A Notes. The entire principal amount of
each Tranche of Series A Notes shall become due and payable on its respective
maturity date.

         Section 8.2. Optional Prepayments with Make-Whole Amount. The Company
may, at its option, upon notice as provided below, prepay at any time all, or
from time to time any part of (but if in part then in a minimum principal amount
of $1,000,000), the outstanding Notes of any Series on any interest payment date
for the Notes of such Series at 100% of the principal amount so prepaid, and
accrued interest thereon to the date of prepayment, plus the Make-Whole Amount
determined for the prepayment date with respect to such principal amount of each
Note of the applicable Series then outstanding. The Company will give each
holder of Notes of the Series to be prepaid written notice of each optional
prepayment under this Section 8.2 not less than 30 days and not more than 60
days prior to the date fixed for such prepayment. Each such notice shall specify
such date, the aggregate principal amount of the Notes and each Series of Notes
to be prepaid on such date, the principal amount of each Note held by such
holder to be prepaid (determined in accordance with Section 8.3), and the
interest to be paid on the prepayment date with respect to such principal amount
being prepaid, and shall be accompanied by a certificate of a Senior Financial
Officer as to the estimated Make-Whole Amount due in connection with such
prepayment (calculated as if the date of such notice were the date of the
prepayment), setting forth the details of such computation. Two Business Days
prior to such prepayment, the Company shall deliver to each holder of Notes of
the Series to be prepaid a certificate of a Senior Financial Officer specifying
the calculation of such Make-Whole Amount as of the specified prepayment date.

         Section 8.3. Allocation of Partial Prepayments. In the case of each
partial prepayment of the Notes pursuant to the provisions of Section 8.2, the
principal amount of the Notes of the Series to be prepaid shall be allocated
among all of the Notes of such Series at the time outstanding in proportion, as
nearly as practicable, to the respective unpaid principal amounts thereof. All
regularly scheduled partial prepayments made with respect to any Additional
Series of Notes pursuant to any Supplement shall be allocated as therein
provided.




                                      -17-
<PAGE>   23


         Section 8.4. Maturity; Surrender, etc. In the case of each prepayment
of Notes pursuant to this Section 8, the principal amount of each Note to be
prepaid shall mature and become due and payable on the date fixed for such
prepayment, together with interest on such principal amount accrued to such date
and the applicable Make-Whole Amount, if any. From and after such date, unless
the Company shall fail to pay such principal amount when so due and payable,
together with the interest and Make-Whole Amount, if any, as aforesaid, interest
on such principal amount shall cease to accrue. Any Note paid or prepaid in full
shall be surrendered to the Company and cancelled and shall not be reissued, and
no Note shall be issued in lieu of any prepaid principal amount of any Note.

         Section 8.5. Purchase of Notes. The Company will not and will not
permit any Restricted Subsidiary or any Affiliate to purchase, redeem, prepay or
otherwise acquire, directly or indirectly, any of the outstanding Notes except
upon the payment or prepayment of the Notes in accordance with the terms of this
Agreement (including any Supplement hereto) and the Notes. The Company will
promptly cancel all Notes acquired by it or any Restricted Subsidiary or any
Affiliate pursuant to any payment, prepayment or purchase of Notes pursuant to
any provision of this Agreement and no Notes may be issued in substitution or
exchange for any such Notes.

         Section 8.6. Make-Whole Amount for Series A Notes. The term "Make-Whole
Amount" means, with respect to a Series A Note of any Tranche, an amount equal
to the excess, if any, of the Discounted Value of the Remaining Scheduled
Payments with respect to the Called Principal of the Series A Note of such
Tranche over the amount of such Called Principal, provided that the Make-Whole
Amount may in no event be less than zero. For the purposes of determining the
Make-Whole Amount, the following terms have the following meanings:

                  "Called Principal" means, with respect to a Series A Note of
         any Tranche, the principal of such Series A Note that is to be prepaid
         pursuant to Section 8.2 or has become or is declared to be immediately
         due and payable pursuant to Section 12.1, as the context requires.

                  "Discounted Value" means, with respect to the Called Principal
         of a Series A Note of any Tranche, the amount obtained by discounting
         all Remaining Scheduled Payments with respect to such Called Principal
         from their respective scheduled due dates to the Settlement Date with
         respect to such Called Principal, in accordance with accepted financial
         practice and at a discount factor (applied on the same periodic basis
         as that on which interest on such Series A Note is payable) equal to
         the Reinvestment Yield with respect to such Called Principal.

                  "Reinvestment Yield" means, with respect to the Called
         Principal of a Series A Note of any Tranche, 0.50% over the yield to
         maturity implied by (i) the ask yields reported, as of 10:00 A.M. (New
         York City time) on the second Business Day preceding the Settlement
         Date with respect to such Called Principal, on the display designated
         as "PX-1" on the Bloomberg Financial Market Services Screen (or such
         other display as may replace Page PX-1 on Bloomberg Financial Market
         Services Screen) for actively traded U.S. Treasury securities having a
         maturity equal to the Remaining Average Life of 







                                      -18-
<PAGE>   24


         such Called Principal as of such Settlement Date, or (ii) if such
         yields are not reported as of such time or the yields reported as of
         such time are not ascertainable, the Treasury Constant Maturity Series
         Yields reported, for the latest day for which such yields have been so
         reported as of the second Business Day preceding the Settlement Date
         with respect to such Called Principal, in Federal Reserve Statistical
         Release H. 15 (519) (or any comparable successor publication) for
         actively traded U.S. Treasury securities having a constant maturity
         equal to the Remaining Average Life of such Called Principal as of such
         Settlement Date. Such implied yield will be determined, if necessary,
         by (a) converting U.S. Treasury bill quotations to bond-equivalent
         yields in accordance with accepted financial practice and (b)
         interpolating linearly between (1) the actively traded U.S. Treasury
         security with the maturity closest to and greater than the Remaining
         Average Life and (2) the actively traded U.S. Treasury security with
         the maturity closest to and less than the Remaining Average Life.

                  "Remaining Average Life" means, with respect to any Called
         Principal, the number of years (calculated to the nearest one-twelfth
         year) obtained by dividing (i) such Called Principal into (ii) the sum
         of the products obtained by multiplying (a) the principal component of
         each Remaining Scheduled Payment with respect to such Called Principal
         by (b) the number of years (calculated to the nearest one-twelfth year)
         that will elapse between the Settlement Date with respect to such
         Called Principal and the scheduled due date of such Remaining Scheduled
         Payment.

                  "Remaining Scheduled Payments" means, with respect to the
         Called Principal of a Series A Note of any Tranche, all payments of
         such Called Principal and interest thereon that would be due after the
         Settlement Date with respect to such Called Principal if no payment of
         such Called Principal were made prior to its scheduled due date,
         provided that if such Settlement Date is not a date on which interest
         payments are due to be made under the terms of such Series A Note, then
         the amount of the next succeeding scheduled interest payment will be
         reduced by the amount of interest accrued to such Settlement Date and
         required to be paid on such Settlement Date pursuant to Section 8.2 or
         12.1.

                  "Settlement Date" means, with respect to the Called Principal
         of a Series A Note of any Tranche, the date on which such Called
         Principal is to be prepaid pursuant to Section 8.2 or has become or is
         declared to be immediately due and payable pursuant to Section 12.1, as
         the context requires.

SECTION 9.           AFFIRMATIVE COVENANTS.

         The Company covenants that so long as any of the Notes are outstanding:

         Section 9.1. Compliance with Law. The Company will, and will cause each
of its Subsidiaries to, comply with all laws, ordinances or governmental rules
or regulations to which each of them is subject, including, without limitation,
Environmental Laws, and will obtain and maintain in effect all licenses,
certificates, permits, franchises and other governmental authorizations
necessary to the ownership of their respective properties or to the conduct of
their 





                                      -19-
<PAGE>   25


respective businesses, in each case to the extent necessary to ensure that
non-compliance with such laws, ordinances or governmental rules or regulations
or failures to obtain or maintain in effect such licenses, certificates,
permits, franchises and other governmental authorizations could not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect.

         Section 9.2. Insurance. The Company will, and will cause each of its
Restricted Subsidiaries to, maintain, with financially sound and reputable
insurers, insurance with respect to their respective properties and businesses
against such casualties and contingencies, of such types, on such terms and in
such amounts (including deductibles, co-insurance and self-insurance, if
adequate reserves are maintained with respect thereto) as is customary in the
case of entities of established reputations engaged in the same or a similar
business and similarly situated.

         Section 9.3. Maintenance of Properties. The Company will, and will
cause each of its Restricted Subsidiaries to, maintain and keep, or cause to be
maintained and kept, their respective properties in good repair, working order
and condition (other than ordinary wear and tear), so that the business carried
on in connection therewith may be properly conducted at all times, provided that
this Section shall not prevent the Company or any Restricted Subsidiary from
discontinuing the operation and the maintenance of any of its properties if such
discontinuance is desirable in the conduct of its business and the Company has
concluded that such discontinuance could not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect.

         Section 9.4. Payment of Taxes and Claims. The Company will, and will
cause each of its Subsidiaries to, file all tax returns required to be filed in
any jurisdiction and to pay and discharge all taxes shown to be due and payable
on such returns and all other taxes, assessments, governmental charges, or
levies imposed on them or any of their properties, assets, income or franchises,
to the extent such taxes and assessments have become due and payable and before
they have become delinquent and all claims for which sums have become due and
payable that have or might become a Lien on properties or assets of the Company
or any Subsidiary, provided that neither the Company nor any Subsidiary need pay
any such tax or assessment or claims if (i) the amount, applicability or
validity thereof is contested by the Company or such Restricted Subsidiary on a
timely basis in good faith and in appropriate proceedings, and the Company or a
Subsidiary has established adequate reserves therefor in accordance with GAAP on
the books of the Company or such Subsidiary or (ii) the nonpayment of all such
taxes and assessments in the aggregate could not reasonably be expected to have
a Material Adverse Effect.

         Section 9.5. Corporate Existence, etc. Subject to Sections 10.6 and
10.7, the Company will at all times preserve and keep in full force and effect
its corporate existence and the Company will at all times preserve and keep in
full force and effect the corporate existence of each of its Restricted
Subsidiaries (unless merged into the Company or a Restricted Subsidiary) and all
rights and franchises of the Company and its Restricted Subsidiaries unless, in
the good faith judgment of the Company, the termination of or failure to
preserve and keep in full force and effect such corporate existence, right or
franchise could not, individually or in the aggregate, have a Material Adverse
Effect.

         period, as the case may be, beginning on the first day of such fiscal
         year and ending as of the end of each completed fiscal quarter of such

shall be so secured, such security to be pursuant to an agreement reasonably
satisfactory in the good faith judgment of the holders of more than 50% in

         Company and its Restricted Subsidiaries, taken as a whole, or the value
         of such property for the purpose of such business;

Company and its Restricted Subsidiaries (other than in transactions in the

         this Agreement (C) such entity would be permitted to incur at least
         $1.00 of additional Priority Debt under the limitations of Section 10.4
         and (D) such entity shall cause to be delivered to each holder of Notes
         an opinion of independent counsel to the effect that all agreements or

Subsidiary as Restricted or Unrestricted, give written notice of such action to
each holder of a Note.

         (b) The Company acknowledges and agrees that if, after the date hereof,
any Person becomes a Restricted Subsidiary, all Debt, leases and other
obligations and all Liens and Investments of such Person existing as of the date

this Agreement, to have been incurred, entered into, made or created at the same
time such Person so becomes a Restricted Subsidiary.

       Section 10.10. Nature of Business. Neither the Company nor any Restricted
Subsidiary will engage in any business if, as a result, the general nature of
the business, taken on a consolidated basis, which would then be engaged in by

the general nature of the business engaged in by the Company and its Restricted
Subsidiaries on the date of this Agreement.

         described in clauses (i) through (vi) above, either individually or
         together with any other such event or events, could reasonably be
         expected to have a Material Adverse Effect.

As used in Section 11(j), the terms "employee benefit plan" and "employee
welfare benefit plan" shall have the respective meanings assigned to such terms
in Section 3 of ERISA.

SECTION 12.          REMEDIES ON DEFAULT, ETC.

        Section 12.1. Acceleration. (a) If an Event of Default with respect to
the Company described in paragraph (g) or (h) of Section 11 (other than an Event
of Default described in clause (i) of paragraph (g) or described in clause (vi)
of paragraph (g) by virtue of the fact that such clause encompasses clause (i)
of paragraph (g)) has occurred, all the Notes of every Series then outstanding
shall automatically become immediately due and payable.

         (b) If any other Event of Default has occurred and is continuing, any
holder or holders of more than 50% in aggregate principal amount of the Notes of
all Series at the time outstanding may at any time at its or their option, by
notice or notices to the Company, declare all the Notes then outstanding to be
immediately due and payable.




                                      -27-
<PAGE>   33


         (c) If any Event of Default described in paragraph (a) or (b) of
Section 11 has occurred and is continuing with respect to any Series of Notes,
any holder or holders of Notes of such Series at the time outstanding affected
by such Event of Default may at any time, at its or their option, by notice or
notices to the Company, declare all the Notes of such Series held by it or them
to be immediately due and payable.

         Upon any Note becoming due and payable under this Section 12.1, whether
automatically or by declaration, such Note will forthwith mature and the entire
unpaid principal amount of such Note, plus (x) all accrued and unpaid interest
thereon and (y) the Make-Whole Amount determined in respect of such principal
amount (to the full extent permitted by applicable law), shall all be
immediately due and payable, in each and every case without presentment, demand,
protest or further notice, all of which are hereby waived. The Company
acknowledges, and the parties hereto agree, that each holder of a Note has the
right to maintain its investment in the Notes free from repayment by the Company
(except as herein specifically provided for), and that the provision for payment
of a Make-Whole Amount by the Company in the event that the Notes are prepaid or
are accelerated as a result of an Event of Default, is intended to provide
compensation for the deprivation of such right under such circumstances.

        Section 12.2. Other Remedies. If any Default or Event of Default has
occurred and is continuing, and irrespective of whether any Notes have become or
have been declared immediately due and payable under Section 12.1, the holder of
any Note at the time outstanding may proceed to protect and enforce the rights
of such holder by an action at law, suit in equity or other appropriate
proceeding, whether for the specific performance of any agreement contained
herein or in any Note, or for an injunction against a violation of any of the
terms hereof or thereof, or in aid of the exercise of any power granted hereby
or thereby or by law or otherwise.

        Section 12.3. Rescission. At any time after any Notes of any Series have
been declared due and payable pursuant to clause (b) or (c) of Section 12.1, the
holders of more than 50% in aggregate principal amount of the Notes of all
Series then outstanding, by written notice to the Company, may rescind and annul
any such declaration and its consequences if (a) the Company has paid all
overdue interest on the Notes of such Series, all principal of and Make-Whole
Amount, if any, on any Notes of such Series that are due and payable and are
unpaid other than by reason of such declaration, and all interest on such
overdue principal and Make-Whole Amount, if any, and (to the extent permitted by
applicable law) any overdue interest in respect of the Notes of such Series, at
the Default Rate, (b) all Events of Default and Defaults, other than non-payment
of amounts that have become due solely by reason of such declaration, have been
cured or have been waived pursuant to Section 17, and (c) no judgment or decree
has been entered for the payment of any monies due pursuant hereto or to any
Note. No rescission and annulment under this Section 12.3 will extend to or
affect any subsequent Event of Default or Default or impair any right consequent
thereon.

        Section 12.4. No Waivers or Election of Remedies, Expenses, etc. No
course of dealing and no delay on the part of any holder of any Note in
exercising any right, power or remedy shall operate as a waiver thereof or
otherwise prejudice such holder's rights, powers or remedies. No right, power or
remedy conferred by this Agreement or by any Note upon any holder thereof shall
be exclusive of any other right, power or remedy referred to herein or therein
or now or 









                                      -28-
<PAGE>   34


hereafter available at law, in equity, by statute or otherwise. Without limiting
the obligations of the Company under Section 15, the Company will pay to the
holder of each Note on demand such further amount as shall be sufficient to
cover all costs and expenses of such holder incurred in any enforcement or
collection under this Section 12, including, without limitation, reasonable
attorneys' fees, expenses and disbursements.

SECTION 13.          REGISTRATION; EXCHANGE; SUBSTITUTION OF NOTES.

        Section 13.1. Registration of Notes. The Company shall keep at its
principal executive office a register for the registration and registration of
transfers of Notes. The name and address of each holder of one or more Notes,
each transfer thereof and the name and address of each transferee of one or more
Notes shall be registered in such register. Prior to due presentment for
registration of transfer, the Person in whose name any Note shall be registered
shall be deemed and treated as the owner and holder thereof for all purposes
hereof, and the Company shall not be affected by any notice or knowledge to the
contrary. The Company shall give to any holder of a Note that is an
Institutional Investor promptly upon request therefor, a complete and correct
copy of the names and addresses of all registered holders of Notes.

        Section 13.2. Transfer and Exchange of Notes. Upon surrender of any Note
at the principal executive office of the Company for registration of transfer or
exchange (and in the case of a surrender for registration of transfer, duly
endorsed or accompanied by a written instrument of transfer duly executed by the
registered holder of such Note or its attorney duly authorized in writing and
accompanied by the address for notices of each transferee of such Note or part
thereof), the Company shall execute and deliver, at the Company's expense
(except as provided below), one or more new Notes (as requested by the holder
thereof) of an identical Series (and of an identical tranche if such Series has
separate tranches) in exchange therefor, in an aggregate principal amount equal
to the unpaid principal amount of the surrendered Note. Each such new Note shall
be payable to such Person as such holder may request and shall be substantially
in the form of the Note of such Series originally issued hereunder or pursuant
to any Supplement. Each such new Note shall be dated and bear interest from the
date to which interest shall have been paid on the surrendered Note or dated the
date of the surrendered Note if no interest shall have been paid thereon. The
Company may require payment of a sum sufficient to cover any stamp tax or
governmental charge imposed in respect of any such transfer of Notes. Notes
shall not be transferred in denominations of less than $100,000, provided that
if necessary to enable the registration of transfer by a holder of its entire
holding of Notes, one Note may be in a denomination of less than $100,000. Any
transferee, by its acceptance of a Note registered in its name (or the name of
its nominee), shall be deemed to have made the representation set forth in
Section 6.2, provided that such holder may (in reliance upon information
provided by the Company, which shall not be unreasonably withheld) make a
representation to the effect that the purchase by such holder of any Note will
not constitute a non-exempt prohibited transaction under Section 406(a) of
ERISA.

        Section 13.3. Replacement of Notes. Upon receipt by the Company of
evidence reasonably satisfactory to it of the ownership of and the loss, theft,
destruction or mutilation of any Note (which evidence shall be, in the case of
an Institutional Investor, notice from such Institutional Investor of such
ownership and such loss, theft, destruction or mutilation), and








                                      -29-
<PAGE>   35

                   (a) in the case of loss, theft or destruction, of indemnity
         reasonably satisfactory to it (provided that if the holder of such Note
         is, or is a nominee for, an original Purchaser or another holder of a
         Note with a minimum net worth of at least $10,000,000, such Person's
         own unsecured agreement of indemnity shall be deemed to be
         satisfactory), or

                   (b) in the case of mutilation, upon surrender and
         cancellation thereof,

the Company at its own expense shall execute and deliver, in lieu thereof, a new
Note of an identical Series (and of an identical tranche if such Series has
separate tranches), dated and bearing interest from the date to which interest
shall have been paid on such lost, stolen, destroyed or mutilated Note or dated
the date of such lost, stolen, destroyed or mutilated Note if no interest shall
have been paid thereon.

SECTION 14.          PAYMENTS ON NOTES.

        Section 14.1. Place of Payment. Subject to Section 14.2, payments of
principal, Make-Whole Amount, if any, and interest becoming due and payable on
the Notes shall be made in Chicago, Illinois at the principal office of Bank of
America in such jurisdiction. The Company may at any time, by notice to each
holder of a Note, change the place of payment of the Notes so long as such place
of payment shall be either the principal office of the Company in such
jurisdiction or the principal office of a bank or trust company in such
jurisdiction.

        Section 14.2. Home Office Payment. So long as any Purchaser or any
Purchaser's nominee shall be the holder of any Note, and notwithstanding
anything contained in Section 14.1 or in such Note to the contrary, the Company
will pay all sums becoming due on such Note for principal, Make-Whole Amount, if
any, and interest by the method and at the address specified for such purpose in
Schedule A hereto or Schedule A attached to any Supplement, or by such other
method or at such other address as such Purchaser shall have from time to time
specified to the Company in writing for such purpose, without the presentation
or surrender of such Note or the making of any notation thereon, except that
upon written request of the Company made concurrently with or reasonably
promptly after payment or prepayment in full of any Note, such Purchaser shall
surrender such Note for cancellation, reasonably promptly after any such
request, to the Company at its principal executive office or at the place of
payment most recently designated by the Company pursuant to Section 14.1. Prior
to any sale or other disposition of any Note held by such Purchaser or such
Purchaser's nominee such Purchaser will, at its election, either endorse thereon
the amount of principal paid thereon and the last date to which interest has
been paid thereon or surrender such Note to the Company in exchange for a new
Note or Notes pursuant to Section 13.2. The Company will afford the benefits of
this Section 14.2 to any Institutional Investor that is the direct or indirect
transferee of any Note.

SECTION 15.          EXPENSES, ETC.

        Section 15.1. Transaction Expenses. Whether or not the transactions
contemplated hereby are consummated, the Company will pay all costs and expenses
(including 







                                      -30-
<PAGE>   36


reasonable attorneys' fees of a special counsel and, if reasonably required,
local or other counsel) incurred by each Purchaser and each other holder of a
Note in connection with such transactions and in connection with any amendments,
waivers or consents under or in respect of this Agreement or the Notes (whether
or not such amendment, waiver or consent becomes effective), including, without
limitation: (a) the costs and expenses incurred in enforcing or defending (or
determining whether or how to enforce or defend) any rights under this Agreement
or the Notes or in responding to any subpoena or other legal process or informal
investigative demand issued in connection with this Agreement or the Notes, or
by reason of being a holder of any Note, and (b) the costs and expenses,
including financial advisors' fees, incurred in connection with the insolvency
or bankruptcy of the Company or any Subsidiary or in connection with any
work-out or restructuring of the transactions contemplated hereby and by the
Notes. The Company will pay, and will save each Purchaser and each other holder
of a Note harmless from, all claims in respect of any fees, costs or expenses,
if any, of brokers and finders (other than those retained by the Purchasers).

        Section 15.2. Survival. The obligations of the Company under this
Section 15 will survive the payment or transfer of any Note, the enforcement,
amendment or waiver of any provision of this Agreement, any Supplement or the
Notes, and the termination of this Agreement or any Supplement.

SECTION 16.      SURVIVAL OF REPRESENTATIONS AND WARRANTIES; ENTIRE AGREEMENT.

         All representations and warranties contained herein or in any
Supplement shall survive the execution and delivery of this Agreement, such
Supplement and the Notes, the purchase or transfer by any Purchaser or any
Additional Purchaser of any Note or portion thereof or interest therein, and may
be relied upon by any subsequent holder of a Note, regardless of any
investigation made at any time by or on behalf of any Purchaser or any
Additional Purchaser or any other holder of a Note. All statements contained in
any certificate or other instrument delivered by or on behalf of the Company
pursuant to this Agreement or any Supplement shall be deemed representations and
warranties of the Company under this Agreement. Subject to the preceding
sentence, this Agreement (including every Supplement) and the Notes embody the
entire agreement and understanding between the Purchasers and the Additional
Purchasers and the Company and supersede all prior agreements and understandings
relating to the subject matter hereof.

SECTION 17.      AMENDMENT AND WAIVER.

        Section 17.1. Requirements. (a) This Agreement (including any Supplement
hereto) and the Notes may be amended, and the observance of any term hereof or
of the Notes may be waived (either retroactively or prospectively), with (and
only with) the written consent of the Company and the holders of Notes holding
more than 50% in aggregate principal amount of the Notes at the time
outstanding, except that (a) no amendment or waiver of any of the provisions of
Section 1, 2, 3, 4, 5, 6 or 21 hereof, or any defined term (as it is used
therein), will be effective as to any Purchaser unless consented to by such
Purchaser in writing, and (b) no such amendment or waiver may, without the
unanimous written consent of all of the holders of Notes of all Series







                                      -31-
<PAGE>   37

at the time outstanding, (i) subject to the provisions of Section 12 relating to
acceleration or rescission, change the amount or time of any prepayment or
payment of principal of, or reduce the rate or change the time of payment or
method of computation of interest or of the Make-Whole Amount on, the Notes of
such Series, (ii) change the percentage of the principal amount of the Notes the
holders of which are required to consent to any such amendment or waiver, or
(iii) amend any of Sections 8, 11(a), 11(b), 12, 17 or 20. For purposes of this
Section 17.1, any amendment to Section 11 which gives the holders of Notes of
any Series greater rights than the holders of Notes of any other Series with
respect to any Default or Event of Default shall require the consent of more
than 50% in aggregate principal amount of the Notes of each Series.

         (b) Supplements. Notwithstanding anything to the contrary contained
herein, the Company may enter into any Supplement providing for the issuance of
one or more Series of Additional Notes consistent with Sections 2.2 and 4.11
hereof without obtaining the consent of any holder of any other Series of Notes.

        Section 17.2.    Solicitation of Holders of Notes.

         (a) Solicitation. The Company will provide each holder of the Notes
(irrespective of the amount of Notes then owned by it) with sufficient
information, sufficiently far in advance of the date a decision is required, to
enable such holder to make an informed and considered decision with respect to
any proposed amendment, waiver or consent in respect of any of the provisions
hereof or of the Notes. The Company will deliver executed or true and correct
copies of each amendment, waiver or consent effected pursuant to the provisions
of this Section 17 to each holder of outstanding Notes promptly following the
date on which it is executed and delivered by, or receives the consent or
approval of, the requisite holders of Notes.

         (b) Payment. The Company will not directly or indirectly pay or cause
to be paid any remuneration, whether by way of supplemental or additional
interest, fee or otherwise, or grant any security, to any holder of Notes as
consideration for or as an inducement to the entering into by any holder of
Notes of any waiver or amendment of any of the terms and provisions hereof
unless such remuneration is concurrently paid, or security is concurrently
granted, on the same terms, ratably to each holder of Notes then outstanding
even if such holder did not consent to such waiver or amendment.

        Section 17.3. Binding Effect, etc. Any amendment or waiver consented to
as provided in this Section 17 applies equally to all holders of Notes and is
binding upon them and upon each future holder of any Note and upon the Company
without regard to whether such Note has been marked to indicate such amendment
or waiver. No such amendment or waiver will extend to or affect any obligation,
covenant, agreement, Default or Event of Default not expressly amended or waived
or impair any right consequent thereon. No course of dealing between the Company
and the holder of any Note nor any delay in exercising any rights hereunder or
under any Note shall operate as a waiver of any rights of any holder of such
Note. As used herein, the term "this Agreement" and references thereto shall
mean this Agreement as it may from time to time be amended or supplemented.






                                      -32-
<PAGE>   38

        Section 17.4. Notes Held by Company, etc. Solely for the purpose of
determining whether the holders of the requisite percentage of the aggregate
principal amount of Notes then outstanding approved or consented to any
amendment, waiver or consent to be given under this Agreement or the Notes, or
have directed the taking of any action provided herein or in the Notes to be
taken upon the direction of the holders of a specified percentage of the
aggregate principal amount of Notes then outstanding, Notes directly or
indirectly owned by the Company, any Restricted Subsidiary or any of its
Affiliates shall be deemed not to be outstanding.

SECTION 18.          NOTICES.

         All notices and communications provided for hereunder shall be in
writing and sent (a) by telefacsimile if the sender on the same day sends a
confirming copy of such notice by a recognized overnight delivery service
(charges prepaid), or (b) by registered or certified mail with return receipt
requested (postage prepaid), or (c) by a recognized overnight delivery service
(with charges prepaid). Any such notice must be sent:

                   (i) if to a Purchaser or such Purchaser's nominee, to such
         Purchaser or it at the address specified for such communications in
         Schedule A, or at such other address as such Purchaser or it shall have
         specified to the Company in writing,

                  (ii) if to any other holder of any Note, to such holder at
         such address as such other holder shall have specified to the Company
         in writing, or

                 (iii) if to the Company, to the Company at its address set
         forth at the beginning hereof to the attention of Chief Financial
         Officer, or at such other address as the Company shall have specified
         to the holder of each Note in writing.

Notices under this Section 18 will be deemed given only when actually received.

SECTION 19.          REPRODUCTION OF DOCUMENTS.

         This Agreement and all documents relating thereto, including, without
limitation, (a) consents, waivers and modifications that may hereafter be
executed, (b) documents received by any holder of Notes at the time such Notes
were issued (except the Notes themselves), and (c) financial statements,
certificates and other information previously or hereafter furnished to any
holder of Notes, may be reproduced by such holder by any photographic,
photostatic, microfilm, microcard, miniature photographic or other similar
process and such holder may destroy any original document so reproduced. The
Company agrees and stipulates that, to the extent permitted by applicable law,
any such reproduction shall be admissible in evidence as the original itself in
any judicial or administrative proceeding (whether or not the original is in
existence and whether or not such reproduction was made by a Purchaser in the
regular course of business) and any enlargement, facsimile or further
reproduction of such reproduction shall likewise be admissible in evidence. This
Section 19 shall not prohibit the Company or any other holder of Notes from
contesting any such reproduction to the same extent that it could contest the
original, or from introducing evidence to demonstrate the inaccuracy of any such
reproduction.

SECTION 20.          CONFIDENTIAL INFORMATION.

         For the purposes of this Section 20, "Confidential Information" means
information delivered to any Purchaser by or on behalf of the Company or any
Restricted Subsidiary in connection with the transactions contemplated by or
otherwise pursuant to this Agreement that is proprietary in nature and that was
clearly marked or labeled or otherwise adequately identified when received by
such Purchaser as being confidential information of the Company or such
Restricted Subsidiary, provided that such term does not include information that
(a) was publicly known or otherwise known to such Purchaser prior to the time of
such disclosure, (b) subsequently becomes publicly known through no act or
omission by such Purchaser or any Person acting on its behalf, (c) otherwise
becomes known to such Purchaser other than through disclosure by the Company or
any Restricted Subsidiary or (d) constitutes financial statements delivered to
such Purchaser under Section 7.1 that are otherwise publicly available. Each
Purchaser will maintain the confidentiality of such Confidential Information in
accordance with procedures adopted by such Purchaser in good faith to protect
confidential information of third parties delivered to such Purchaser, provided
that such Purchaser may deliver or disclose Confidential Information to (i) such
Purchaser's directors, trustees, officers, employees, agents, attorneys and
affiliates (to the extent such disclosure reasonably relates to the
administration of the investment represented by such Purchaser's Notes), (ii)
such Purchaser's financial advisors and other professional advisors who agree to
hold confidential the Confidential Information substantially in accordance with
the terms of this Section 20, (iii) any other holder of any Note, (iv) any
Institutional Investor to which such Purchaser sells or offers to sell such Note
or any part thereof or any participation therein (if such Person has agreed in
writing prior to its receipt of such Confidential Information to be bound by the
provisions of this Section 20), (v) any Person from which such Purchaser offers
to purchase any security of the Company (if such Person has agreed in writing
prior to its receipt of such Confidential Information to be bound by the
provisions of this Section 20), (vi) any federal or state regulatory authority
having jurisdiction over such Purchaser, (vii) the National Association of
Insurance Commissioners or any similar organization, or any nationally
recognized rating agency that requires access to information about such
Purchaser's investment portfolio or (viii) any other Person to which such
delivery or disclosure may be necessary or appropriate (w) to effect compliance
with any law, rule, regulation or order applicable to such Purchaser, (x) in
response to any subpoena or other legal process, (y) in connection with any
litigation to which such Purchaser is a party or (z) if an Event of Default has
occurred and is continuing, to the extent such Purchaser may reasonably
determine such delivery and disclosure to be necessary or appropriate in the
enforcement or for the protection of the rights and remedies under such
Purchaser's Notes and this Agreement. Each holder of a Note, by its acceptance
of a Note, will be deemed to have agreed to be bound by and to be entitled to
the benefits of this Section 20 as though it were a party to this Agreement. On
reasonable request by the Company in connection with the delivery to any holder
of a Note of information required to be delivered to such holder under this
Agreement or requested by such holder (other than a holder that is a party to
this Agreement or its nominee), such holder will enter into an agreement with
the Company embodying the provisions of this Section 20.

SECTION 21.          SUBSTITUTION OF PURCHASER.

         Each Purchaser shall have the right to substitute any one of such
Purchaser's Affiliates as the purchaser of the Notes that such Purchaser has
agreed to purchase hereunder, by written notice to the Company, which notice
shall be signed by both such Purchaser and such Affiliate, shall contain such
Affiliate's agreement to be bound by this Agreement and shall contain a
confirmation by such Affiliate of the accuracy with respect to it of the
representations set forth in Section 6. Upon receipt of such notice, wherever
the word "Purchaser" is used in this Agreement (other than in this Section 21),
such word shall be deemed to refer to such Affiliate in lieu of such Purchaser.
In the event that such Affiliate is so substituted as a purchaser hereunder and
such Affiliate thereafter transfers to such Purchaser all of the Notes then held
by such Affiliate, upon receipt by the Company of notice of such transfer,
wherever the word "Purchaser" is used in this Agreement (other than in this
Section 21), such word shall no longer be deemed to refer to such Affiliate, but
shall refer to such Purchaser, and such Purchaser shall have all the rights of
an original holder of the Notes under this Agreement.

SECTION 22.          MISCELLANEOUS.

        Section 22.1. Successors and Assigns. All covenants and other agreements
contained in this Agreement (including all covenants and other agreements
contained in any Supplement) by or on behalf of any of the parties hereto bind
and inure to the benefit of their respective successors and assigns (including,
without limitation, any subsequent holder of a Note) whether so expressed or
not.

        Section 22.2. Payments Due on Non-Business Days. Anything in this

Mr. J. Kelley Williams
Chief Executive Officer/Chairman of the Board
ChemFirst Inc.
700 North Street
Jackson, MS  39202          PRIVILEGED AND CONFIDENTIAL

RE: Termination Agreement


Dear Kelley:

          ChemFirst Inc. (the "Company") considers it essential to the best
interests of its stockholders to foster the continuous employment of key
management personnel. In this connection, the Board of Directors of the Company
(the "Board") recognizes that, as is the case with many publicly held
corporations and their subsidiaries, the possibility of a Change in Control may
exist and that such possibility, and the uncertainty and questions which it may
raise, may result in the departure or distraction of management personnel to the
detriment of the Company and its stockholders.

          The Board has determined that appropriate steps should be taken to
reinforce and encourage the continued attention and dedication of the Company's
management to their assigned duties, without distraction in the face of
potentially disturbing circumstances arising from the possibility of a Change in
Control of the Company, although no such change is now contemplated.

          In order to induce you to remain in the employ of the Company and in
consideration of your agreement set forth in Subsection 2(iii) hereto, the
Company agrees that you shall receive the severance benefits set forth in this
letter agreement ("Agreement") in the event your employment with the Company is
terminated subsequent to a "Change in Control" of the Company (as defined in
Section 2 hereof) under the circumstances described below. This letter, however,
does not otherwise change your employment arrangements and except for the
conditions contained therein pertaining to a Change in Control, your continued
employment continues to be subject to the will of the Board of the Company.


          1. Term of Agreement. This Agreement shall be deemed effective on June
1, 1996 and shall continue in effect through May 31, 1999 (the "Original Term");
provided, however, that commencing on June 1, 1999, the term of this Agreement
shall automatically be extended for one additional term of three (3) years
beyond May 31, 1999, unless not later than June 30 of that year, the

Company shall have given notice that it does not wish to extend this Agreement.
Notwithstanding the above, if a Change in Control (as defined in Section 2
below) of the Company shall have occurred during the original or extended term
of this Agreement, this Agreement shall continue in effect for a period of three
(3) years beyond the month in which such Change in Control occurred; provided
that, if you qualify as a Bona Fide Executive ("Bona Fide Executive") as that
term is defined under the Fair Labor Standards Act (29 C.F.R. Section 1625.12),
as may be amended, in no event shall this Agreement extend beyond the end of the
month in which you reach the age of 70 years.


          2. Change in Control.

               (i) No benefits shall be payable hereunder unless there shall

               directly or indirectly, by the stockholders of the Company in
               substantially the same proportions as their ownership of stock of

               (as defined in Rule 13d-3 under the Exchange Act), directly or
               indirectly, of securities of the Company representing twenty

                    (B) during any period of two consecutive years (not
               including any period prior to the execution of this Agreement),
               individuals who at the beginning of such period constitute the
               Board and any new director (other than a director designated by a
               Person who has entered into an agreement with the Company to
               effect a transaction described in clause (A), (C) or (D) of this
               Subsection) whose election by the Board or nomination for
               election by the Company's stockholders was approved by a vote of
               at least two-thirds (2/3) of the directors then still in office
               who either were directors at the beginning of the period or whose
               election or nomination for election was previously so approved,
               cease for any reason to constitute a majority thereof; or

                    (C) the shareholders of the Company approve a merger or
               consolidation of the Company with any other corporation, other
               than (i) a merger or consolidation which would result in the
               voting securities of the Company outstanding immediately prior
               thereto continuing to represent (either by remaining outstanding
               or be being converted into voting securities of the surviving
               entity or any parent thereof), in combination with the ownership
               of any trustee or other fiduciary holding securities under an

               such surviving entity or any parent thereof

                                                                               3


               outstanding immediately after such merger or consolidation, or
               (ii) a merger or consolidation effected to implement a
               recapitalization of the Company (or similar translation) in which
               no Person is or becomes the beneficial owner (determined pursuant
               to Subsection A above) of twenty percent (20%) or more of the
               combined voting power of the Company's then outstanding
               securities; or

                    (D) the shareholders of the Company approve a plan of
               complete liquidation of the Company or an agreement for the sale
               or disposition by the Company of all or substantially all the
               Company's assets.

               (ii) For purposes of this Agreement, a "Potential Change in
          Control" of the Company shall be deemed to have occurred if:

                    (A) the Company enters into an agreement, the consummation
               of which would result in the occurrence of a Change in Control of
               the Company;

                    (B) any person (including the Company) publicly announces an
               intention take or to consider taking actions which if consummated
               would constitute a Change in Control of the Company;

                    (C) any person, other than a trustee or other fiduciary
               holding securities under an employee benefit plan of the Company
               or a corporation owned, directly or indirectly, by the
               stockholders of the Company in substantially the same proportions
               as their ownership of stock of the Company, who is or becomes the
               beneficial owner, directly or indirectly, of securities of the
               Company representing nine and a half (9.5%) percent or more of
               the combined voting power of the Company's then outstanding
               securities, increases his beneficial ownership of such securities
               by five (5%) or more over the amount theretofore owned by such
               person; or

                    (D) the Board adopts a resolution to the effect that, for
               purposes of this Agreement, a Potential Change in Control of the
               Company has occurred.

               (iii) You agree that, subject to the terms and conditions of this
          Agreement, in the event of a Potential Change in Control of the
          Company, you will remain in the employ of the Company until the
          earliest of (A) a date which is six (6) months from the occurrence of
          such Potential Change in Control of the Company, (B) the termination
          by you of your employment by reason of Disability, as defined in
          Subsection 3(i), or (C) the occurrence of a Change in Control of the
          Company.

               (iv) Notwithstanding the foregoing, neither a "Change in Control"
          nor a "Potential Change in Control" shall be deemed to have occurred
          by virtue of the Company entering into any agreement with respect to,
          the public announcement of, the approval by the Company's shareholders
          or directors of, or the consummation of, any transaction or series of
          integrated transactions (including any merger or other business
          combination transaction) entered into in connection with, or expressly
          conditioned upon the occurrence of, a Spin-Off Transaction (as 


<PAGE>   4

                                                                               4


          defined below) immediately following which the recordholders of the
          common stock of the Company immediately prior to such transaction or
          series of transactions continue to have substantially the same
          proportionate ownership in an entity (the "Spun-Off Entity") which
          owns all or substantially all of the assets of either of the Company's
          Principal Businesses (as defined below) immediately following such
          transaction or series of transactions (such transaction or series of
          transactions, a "Spin-Off Transaction"); provided that such Spin-Off
          Transaction (including any related merger or other business
          combination transaction) has been approved by a vote of a majority of
          the Company's Continuing Directors (as defined below) then in office.
          For purposes of this Agreement (1) "Principal Businesses" shall mean
          either of the Company's Chemical or Fertilizer businesses as described
          in the Company's Annual Report on Form 10-K for the fiscal year ended
          June 30, 1995 and (2) "Continuing Director" shall mean any member of
          the Board of Directors of the Company who is a member of the Board of
          Directors as of the date of this Agreement and any person who
          subsequently becomes a member of the Board of Directors, if such
          person's nomination for election or election to the Board of Directors
          is recommended or approved by a majority of the Continuing Directors.

          3. Termination Following Change in Control. If any of the events
described in Subsection 2(i) hereof constituting a Change in Control of the
Company shall have occurred, you shall be entitled to the benefits provided in
Subsection 4(iii) and (iv) hereof upon the subsequent termination of your
employment during the term of this Agreement unless such termination is (A)
because of your death or Disability as defined in Section 3(i), or (B) by the
Company for Cause, or upon your resignation within thirty-six (36) months of the
occurrence of such events as specified in Section 2.

               (i) Disability. If, as a result of your incapacity due to
          physical or mental illness, you shall have been absent from the
          full-time performance of your duties with the Company for six (6)
          consecutive months, and within thirty (30) days after written notice
          of termination is given you shall not have returned to the full-time
          performance of your duties, your employment may be terminated for
          "Disability".

               (ii) Cause. Termination by the Company of your employment for
          "Cause" shall mean termination upon (A) the willful and continued
          failure by you to substantially perform your duties with the Company
          (other than any such failure resulting from your incapacity due to
          physical or mental illness) or any such actual or anticipated failure
          after the issuance of a Notice of Termination after a written demand
          for substantial performance is delivered to you by the Board, which
          demand specifically identifies the manner in which the Board believes
          that you have not substantially performed your duties, or (B) the
          willful engaging by you in conduct which is demonstrably and
          materially injurious to the Company, monetarily or otherwise. For
          purposes of this Subsection, an act, or failure to act, shall be
          deemed "willful" if done, or omitted to be done, by you other than in
          good faith and without reasonable belief that your action or omission
          was in the best interest of the Company. Notwithstanding the
          foregoing, you shall not be deemed to have been terminated for Cause
          unless and until there shall have been delivered to you a copy of a
          resolution duly adopted by the affirmative vote of a minimum of
          three-quarters (3/4) of the entire membership of the 


<PAGE>   5

                                                                               5


          Board at a meeting of the Board called and held for such purpose
          (after reasonable notice to you and opportunity for you, together with
          your counsel, to be heard before the Board), finding that in good
          faith opinion of the Board you were guilty of conduct set forth above
          in clauses (A) or (B) of the first sentence of this Subsection and
          specifying the particulars thereof in detail.

                  (iii) Notice of Termination. Any purported termination of your
          employment by the Company or by you shall be communicated by written
          Notice of Termination to the other party hereto in accordance with
          Section 6 hereof. For purposes of this Agreement, a "Notice of
          Termination" shall mean a notice which shall indicate the specific
          termination provision in this Agreement relied upon and shall set
          forth in reasonable detail the facts and circumstances claimed to
          provide a basis for termination of your employment under the
          provision so indicated.
          
               (iv) Date of Termination, Etc. "Date of Termination" shall mean
          the following: (A) if your employment is terminated for Disability,
          thirty (30) days after Notice of Termination is given (provided that
          you shall not have returned to the full-time performance of your
          duties during such thirty (30) day period), and (B) if your employment
          is terminated pursuant to Subsection (ii) above or for any other
          reason (other than Disability), the date specified in the Notice of
          Termination (which, in the case of a termination pursuant to
          Subsection (ii) above shall not be less than thirty (30) days from the
          date such Notice of Termination is given); provided that if within
          fifteen (15 days after any Notice of Termination is given, or if
          later, prior to the Date of Termination (as determined without regard
          to this provision), the party receiving such Notice of Termination
          notifies the other party that a dispute exists concerning the
          termination, the Date of Termination shall be the date on which the
          dispute is finally determined, either by mutual written agreement of
          the parties, by a binding arbitration award, or by a final judgment,
          order or decree of a court of competent jurisdiction (which is not
          appealable or with respect to which the time for appeal therefrom has
          expired and no appeal has been perfected); provided further that the
          Date of Termination shall be extended by a notice of dispute only if
          such notice is given in good faith and the party giving such notice
          pursues the resolution of such dispute with reasonable diligence.
          Notwithstanding the pendency of any such dispute, the Company will
          continue to pay you your full compensation in effect when the notice
          giving rise to the dispute was given (including, but not limited to
          base salary) and continue your participation in all compensation,
          benefit and insurance plans in which you were participating when the
          notice giving rise to the dispute was given, until the dispute is
          finally resolved in accordance with this Subsection. Amounts paid
          under this Subsection are in addition to all other amounts due under
          this Agreement and shall not be offset against or reduce any other
          amounts due under this Agreement.

          4. Compensation Upon Termination or During Disability. Following a
          Change in Control of the Company, as defined by Subsection 2(i), upon
          termination of your employment or during a period of disability, you
          shall be entitled to the following benefits.

                                                                               6


               (i) During any period that you fail to perform your full-time
          duties with the Company as a result of incapacity due to physical or
          mental illness, you shall continue to receive your base salary at the
          rate in effect at the commencement of any such period, together with
          all compensation payable to you under the Company's annual bonus plan,
          the First Mississippi Corporation 1980 Long-Term Incentive Plan, the
          First Mississippi Corporation 1988 Long-Term Incentive Plan, the First
          Mississippi Corporation 1995 Long-Term Incentive Plan, or other plan
          during such period, until this Agreement is terminated pursuant to
          Section 3(i) hereof. Thereafter your benefits shall be determined
          under the Company's retirement, insurance and other compensation
          programs then in effect in accordance with the terms of such programs.

               (ii) If your employment shall be terminated by the Company for
          Cause or by you other than for Disability, or death, the Company shall
          pay you your full base salary through the Date of Termination at the
          rate in effect at the time Notice of Termination is given, plus all
          other amounts to which you are entitled under any compensation plan of
          the Company at the time such payments are due, and the Company shall
          have no further obligations to you under this Agreement.

               (iii) If your employment by the Company shall be terminated (a)
          by the Company other than for Cause or Disability, then you shall be
          entitled to the benefits provided below:

                    (A) The Company shall pay you your full base salary through
                    the Date of Termination at the rate in effect at the time
                    Notice of Termination is given, plus all other amounts to
                    which you are entitled under any compensation plan of the
                    Company, at the time such payments are due, except as
                    otherwise provided below.

                    (B) (1) In lieu of any further salary payments to you for
                    periods subsequent to the Date of Termination, the Company
                    shall pay to you, subject to subsection 2 below, a lump sum
                    severance payment (together with the payments provided in
                    Paragraphs C, E and F below and any payment you may receive
                    pursuant to Paragraph D below, the "Severance Payments")
                    equal to 3 times the sum of (i) your average annual base
                    salary for the five (5) full years preceding the year in
                    which the Date of Termination occurs averaged over said five
                    (5) full years, and (ii) either the average annual bonus
                    earned by you with respect to such five (5) year period, or
                    the average annual bonus earned by you with respect to such
                    five (5) year period immediately preceding the date of the
                    Change in Control, whichever is higher (taking the value of
                    such bonuses into account whether paid in cash or defined or
                    converted into another form of compensation under any
                    Company plan).

                         (2) Notwithstanding subsection (B)(1) above, if you
                    will reach the age of 70 years within 36 months after the
                    Date of Termination, then the lump sum severance payment
                    calculated in subsection (B)(1) above shall be reduced by
                    multiplying such payment by a fraction, the numerator of
                    which shall equal 


<PAGE>   7

                                                                               7


                    one plus the number of full calendar months between the Date
                    of Termination and the date on which you attain the age of
                    70, if you qualify as a Bona Fide Executive, and the
                    denominator of which shall equal 36.

                    (C) The Company shall continue to provide you with medical
               insurance, life insurance and disability insurance in the amounts
               and upon the terms and conditions present immediately prior to
               Notice of Termination for a period of three years following the
               Date of Termination. However, if during such three year period
               you (i) become re-employed with another employer and you are
               eligible to receive medical or other welfare benefits under
               another employer provided plan, or (ii) you reach the age of 70
               years and do not qualify as a Bona Fide Executive, then the
               medical and other welfare benefits described above shall no
               longer be provided by the Company. In the event that the Company
               cannot, despite its best efforts, provide such coverage under its
               benefit plans, it shall arrange for equivalent coverage outside
               such plans.

                    (D) Notwithstanding any provision of the Company's Long-Term
               Incentive Plans as amended from time to time, or any other
               compensation arrangements then in effect, the Company shall pay
               to you a lump sum amount equal to the sum of any incentive
               compensation which has been allocated or awarded to you for a
               year or other measuring period preceding the Date of Termination,
               but has not yet been paid.

                    (E) Except for Incentive Stock Options ("ISOs") which are
               hereby specifically excluded, in lieu of shares of common stock
               of the Company ("Company Shares") issuable upon exercise of
               outstanding options ("Options"), granted to you under the
               Company's Long-Term Incentive Plans as amended from time to time,
               or any other plan then in effect (which Options shall be canceled
               upon the making of the payment referred to below), unless you
               notify the Company by giving notice in accordance with Section 6
               hereof within fifteen (15) days after receipt of Notice of
               Termination that you do not wish such payment, the Company shall
               pay to you not later then the fifth day following the Date of
               Termination, an amount in cash equal to the product of (i) the
               difference (to the extent that such difference is a positive
               number) obtained by subtracting the per share exercise price of
               each Option held by you whether or not then fully exercisable
               from the higher of (A) the closing price of Company Shares as
               reported on the New York Stock Exchange on the Date of
               Termination, or (B) the highest per share price of Company Shares
               actually paid in connection with any Change in Control of the
               Company, and (ii) the number of Company Shares covered by each
               such Option. In lieu of convertible debentures of the Company
               ("the Debentures") issuable upon exercise of outstanding options
               ("Debenture Options") granted to you under the Company's
               Long-Term Incentive Plans, as amended from time to time, or any
               other plan then in effect (which Debenture Options shall be
               canceled upon the making of the payment referred to below),
               unless you notify the Company by giving notice in accordance with
               Section 6 hereof within fifteen (15) days after receipt of Notice
               of Termination that you do not wish to receive such payment, the
               Company will pay to you, not later than the fifth

               (5th) day following the Date of Termination, an amount in cash
               equal to the product of (i) the difference (to the extent that
               such difference is a positive number) obtained by subtracting the
               per share price at which the Debentures would be convertible into
               Company Shares whether or not then fully exercisable from the
               higher of (A) the closing price of Company Shares as reported on
               the New York Stock Exchange on the Date of Termination, or (B)
               the highest per share price for Company Shares actually paid in
               connection with any Change in Control of the Company, and (ii)
               the number of Company Shares issuable upon conversion of the
               Debentures covered by the Debenture Options. In lieu of any
               conversion rights under any outstanding Debentures issued upon
               the exercise of Debenture Options (which Debentures shall be
               canceled upon the making of the payment referred to below),
               unless you notify the Company by giving notice in accordance with
               Section 6 hereof within fifteen (15) days after receipt of Notice
               of Termination that you do not wish such payment, the Company
               will pay to you an amount in cash equal to the product of (i) the
               higher of (A) the closing price of Company Shares as reported on
               the New York Stock Exchange on the Date of Termination or (B) the
               highest per share price for Company Shares actually paid in
               connection with any Change in Control of the Company, and (ii)
               the number of Company Shares into which such Debentures are then
               convertible. In lieu of any rights under any outstanding
               Performance Shares or Performance Units (as each term is defined
               in the First Mississippi Corporation 1995 Long-Term Incentive
               Plan) granted to you by the Company, the Company shall, pursuant
               to the terms and conditions of the First Mississippi Corporation
               1995 Long-Term Incentive Plan, pay to you in cash an amount equal
               to the value of such Performance Shares or Performance Units.

                    (F) If on the Date of Termination, you are not 100% vested
               under the Retirement Plan For Employees of First Mississippi
               Corporation and the corresponding provisions of the First
               Mississippi Corporation Benefits Restoration Plan (together the
               "Retirement Plan"), the Company shall pay you a lump sum equal to
               the present value of a straight life annuity benefit commencing
               at the earliest date you could have elected to receive benefits
               under the Retirement Plan (using the interest rate and the
               mortality table then in use under the Retirement Plan) to provide
               the excess of:

                         (i) an aggregate benefit equal to the benefit that
                    would have been paid under the Retirement Plan if you were
                    100% vested under such Retirement Plan, over

                         (ii) the aggregate benefit actually payable under the
                    Retirement Plan.

               In addition, if on the Date of Termination you are not 100%
               vested under either the First Mississippi Corporation 401(k)
               Savings Plan and the corresponding provisions of the First
               Mississippi Corporation Benefits Restoration Plan (effective
               March 1, 1989),

               the Company shall pay you a lump sum equal to the current amount
               forfeited under each such plan.

                    (G) The Company shall also pay to you all legal fees and
               expenses incurred by you as a result of such termination
               (including all such fees and expenses, if any, incurred in
               contesting or disputing any such termination or in seeking to
               obtain or enforce any right or benefit provided by this Agreement
               or in connection with any tax audit or proceeding to the extent
               attributable to the application of Section 4999 of the Internal
               Revenue Code of 1986, as amended (the "Code") to any payment or
               benefit provided hereunder).

                    (H) The payments provided for in paragraphs (A), (B), (D),
               (E) and (F) above and in Paragraph (iv) below, shall be made not
               later than the fifth (5th) day following the Date of Termination,
               provided, however, that if the amounts of such payments cannot be
               finally determined on or before such day, the Company shall pay
               to you on such day an estimate, as determined in good faith by
               the Company, of the minimum amount of such payments and shall pay
               the remainder of such payments (together with interest at the
               rate provided in Section 1274(b)(2)(B) of the Code) as soon as
               the amount thereof can be determined, but in no event later than
               the thirtieth (30th) day after the Date of Termination. In the
               event that the amount of the estimated payments exceeds the
               amount subsequently determined to have been due, such excess
               shall constitute a loan by the Company to you payable on the
               fifth (5th) day after demand by the Company (together with
               interest at the rate provided in Section 1274(b)(2)(B) of the
               Code).

               (iv) In the event that you become entitled to the Severance
          Payments or to any other payments or benefits received or to be
          received by you in connection with a Change in Control of the Company
          or your termination of employment (whether pursuant to the terms of
          this Agreement or any other plan, arrangement or agreement with the
          Company, (collectively with the Severance Payments, the "Total
          Payments"), and if any of the Total Payments will be subject to the
          tax (the "Excise Tax") imposed by Section 4999 of the Code, the
          Company shall pay to you at the time specified in paragraph (H),
          above, an additional amount (the "Gross-Up Payment") such that the net
          amount retained by you, after deduction of any Excise Tax on the Total
          Payments and any income tax, employment tax and Excise Tax upon the
          payment provided for by this paragraph, shall be equal to the Total
          Payments. For purposes of determining whether any of the Total
          Payments will be subject to the Excise Tax and the amount of such
          Excise Tax, (i) the Total Payments shall be treated as "parachute
          payments" within the meaning of Section 280G(b)(2) of the Code, and
          all "excess parachute payments" within the meaning of Section
          280G(b)(2) shall be treated as subject to the Excise Tax, unless in
          the opinion of tax counsel selected by the Company's independent
          auditors and acceptable to you such other payments or benefits (in
          whole or in part) do not constitute parachute payments, or such excess
          parachute payments (in whole or in part) represent reasonable
          compensation for services actually rendered within the meaning of
          Section 280G(b)(4) of the Code in excess of the base amount within the
          meaning of Section 280G(b)(3) of the Code, or are otherwise not
          subject to the Excise Tax, (ii) the amount of the Total Payments which
          shall

<PAGE>   10

                                                                              10


          be treated as subject to the Excise Tax shall be equal to the lesser
          of (A) the total amount of the Total Payments or (B) the amount of
          excess parachute payments within the meaning of Section 280(b)(1)
          (after applying clause (i), above), and (iii) the value of any
          non-cash benefits or any deferred payment or benefit shall be
          determined by the Company's independent auditors in accordance with
          the principles of Sections 280(G)(d)(3) and (4) of the Code. For
          purposes of determining the amount of the Gross-Up Payment, you shall
          be deemed to pay income taxes at the highest marginal rate of income
          taxation in the calendar year in which the Gross-Up Payment is to be
          made. In the event that the Excise Tax is subsequently determined to
          be less than the amount taken into account hereunder at the time of
          termination of your employment, you shall repay to the Company at the
          time that the amount of such reduction in Excise Tax is finally
          determined the portion of the Gross-Up Payment attributable to such
          reduction (plus the portion of the Gross-Up Payment attributable to
          the Excise Tax and income tax imposed on the Gross-Up Payment being
          repaid by you if such repayment results in a reduction in Excise Tax
          and/or an income tax deduction) plus interest on the amount of such
          repayment at the rate provided in Section 127(b)(2)(B) of the Code. In
          the event that the Excise Tax is determined to exceed the amount taken
          into account hereunder at the time of the termination of your
          employment (including by reason of any payment the existence or amount
          of which cannot be determined at the time of the Gross-Up Payment),
          the Company shall make an additional Gross-Up Payment in respect of
          such excess (plus any interest payable with respect to such excess) at
          the time that the amount of such excess is finally determined.

               (v) Notwithstanding anything to the contrary in this Agreement,
          amounts received under paragraph (iii) above shall be in lieu of any
          other amount of severance relating to salary or bonus continuation to
          be received by you upon termination of employment under any severance
          plan, policy or arrangement of the Company.

               (vi) You shall not be required to mitigate the amount of any
          payment provided for in this Paragraph 4 by seeking other employment
          or otherwise, nor shall the amount of any payment or benefit provided
          for in this Paragraph 4 be reduced by any compensation or benefits
          earned by you as the result of employment by another employer (except
          as provided in paragraph (iii)(C) above), by retirement benefits, by
          offset against any amount claimed to be owed by you to the Company, or
          otherwise.

               (vii) In addition to all other amounts payable to you under this
          Paragraph 4, you shall be entitled to receive all benefits payable to
          you under the 401(k) Savings Plan, and any other plan or agreement
          relating to retirement benefits.

          5. Successors; Binding Agreement.

               (i) The Company will require any successor (whether direct or
          indirect, by purchase, merger, consolidation or otherwise) to all or
          substantially all of the business and /or assets of the Company to
          expressly assume and agree to perform this Agreement in the same
          manner and to the same extent that the Company would be required to
          perform it if no such succession had taken place. Failure of the
          Company to obtain such assumption and agreement

<PAGE>   11

                                                                              11


          prior to the effectiveness of any such succession shall be a breach of
          this Agreement and shall entitle you to compensation from the Company
          in the same amount and on the same terms as you would be entitled to
          hereunder if you terminated your employment for any reason following a
          Change in Control of the Company, except that for purposes of
          implementing the foregoing, the date on which any such succession
          becomes effective shall be deemed the Date of Termination. As used in
          this Agreement, "Company" shall mean the Company as hereinbefore
          defined and any successor to its business and/or assets as aforesaid
          which assumes and agrees to perform this Agreement by operation of
          law, or otherwise.

               (ii) This Agreement shall inure to the benefit of and be
          enforceable by your personal or legal representatives, executors,
          administrators, successors, heirs, distributees, devisees and
          legatees. If you should die while any amount would still be payable to
          you hereunder if you had continued to live, all such amounts, unless
          otherwise provided herein, shall be paid in accordance with the terms
          of this Agreement to your devisee, legatee or other designee or, if
          there is no such designee, to your estate. Notwithstanding the
          foregoing, you and the Company hereby agree that, upon the
          distribution (the "Distribution") of shares of common stock of the
          Spun-Off Entity to stockholders of the Company in a Spin-Off
          Transaction, the Spun-Off Entity shall assume all of the obligations
          and succeed to all of the rights of the Company under this Agreement,
          the Company shall be released of all of its obligations under this
          Agreement and thereafter, as used in this Agreement, the term
          "Company" shall mean the Spun-Off Entity and any successor to its
          business and/or assets which assumes and agrees to perform this
          Agreement by operation of law or otherwise. This Agreement shall
          terminate and be of no further force and effect and you hereby agree
          to release the Company and the Spun-Off Entity from any obligations
          hereunder upon the Distribution if, as of the Distribution, you are
          not employed by the Spun-Off Entity or one of its direct or indirect
          subsidiaries.

          6. Notices. For the purpose of this Agreement, notices and all other
communications provided for in the Agreement shall be in writing and shall be
deemed to have been duly given when delivered or mailed by United States
registered mail, return receipt requested, postage prepaid, addressed to the
respective addresses set forth on the first page of this Agreement, provided
that all notices to the Company shall be directed to the attention of the Board
with a copy to the Secretary of the Company, or to such other address as either
party may have furnished to the other in writing in accordance herewith, except
that notice of change of address shall be effective only upon receipt.

          7. Miscellaneous. No provision of this Agreement may be modified,
waived or discharged unless such waiver, modification or discharge is agreed to
in writing and signed by you and such officer as may be specifically designated
by the Board. No waiver by either party hereto at any time of any breach by the
other party hereto of, or compliance with, any condition or provision of this
Agreement to be performed by such other party shall be deemed a waiver of
similar or dissimilar provisions or conditions at the same or at any prior or
subsequent time. No agreements or representations, oral or otherwise, express or
implied, with respect to the subject matter hereof have been made by either
party which are not expressly set forth in this Agreement. The validity,
interpretation, construction and performance of this Agreement shall be governed
by the laws of the State of Mississippi. All references to Sections of the
Exchange Act or the Code shall be deemed also

<PAGE>   12

                                                                              12


to refer to any successor provisions to such Sections. Any payments provided for
hereunder shall be paid net of any applicable withholding required under
federal, state or local law. The obligations of the Company under Paragraph 4
shall survive the expiration of the term of this Agreement.

          8 Validity. The invalidity or unenforceability of any provision of
this Agreement shall not affect the validity or enforceability of any other
provision of this Agreement, which shall remain in full force and effect.

          9. Counterparts. This Agreement may be executed in several
counterparts, each of which shall be deemed to be an original, but all of which
together will constitute one and the same instrument.

          10. Amendment. This Agreement amends and restates in its entirety that
certain Termination Agreement dated May 29, 1996 between J. Kelley Williams and
First Mississippi Corporation, which was assigned to and assumed by ChemFirst
Inc.

If this letter sets forth our agreement on the subject matter hereof, please
sign and return the enclosed copy of this letter to Teresa Holland in the CEM
human resources department which will then constitute our agreement on this
subject.



Sincerely yours,

Dear Fellow Shareholders

CHEMFIRST PRODUCES CHEMICALS FOR ELECTRONIC, PHARMACEUTICAL, POLYMER,
AGRICULTURAL, AND POLYURETHANE MARKETS. WE ARE NOW EXCLUSIVELY FOCUSED ON
CHEMICALS. WE HAVE RECLASSIFIED ENGINEERED PRODUCTS AND SERVICES AS DISCONTINUED
OPERATIONS IN ADDITION TO STEEL PENDING DISPOSITION OF THESE BUSINESSES. DURING
THE YEAR WE MADE SUBSTANTIAL INVESTMENTS IN TECHNOLOGY AND CAPACITY ADDITIONS TO
BUILD ON MARKET AND TECHNOLOGY LEADERSHIP IN CHEMICALS AND TO TAKE ADVANTAGE OF
GROWTH OPPORTUNITIES. WE EXPECT TO SEE RESULTS IN 1999.

         EARNINGS IN 1998 SUFFERED FROM DEPRESSED CONDITIONS IN MANY OF OUR
MARKETS. VOLUME DECLINED AND PRICES FELL FOR SOME PRODUCTS DUE TO WEAKER DEMAND,
EXCESS CAPACITY, THE STRONG DOLLAR, AND DETERIORATING ECONOMIES IN THE FAR EAST
AND OTHER PARTS OF THE WORLD. AGRICULTURAL CHEMICAL DEMAND ALSO FELL DUE TO
COMPETITION FROM BIOTECHNOLOGY. UNUSUAL AND HOPEFULLY NONRECURRING PRODUCTION
PROBLEMS ALSO HURT RESULTS.

         Earnings from continuing operations excluding special items were down
about 30% versus 1997. Peer company earnings were also down, about 25%. The
decline in our earnings reflected development expenses for chemical mechanical
planarization (CMP) for electronic chemical markets as well as the other factors
noted above. Total sales of $305 million were about the same as last year. A 22%
increase in electronic chemical sales was offset by decreased sales in other
areas.

         Continuing operations include Electronic and Other Specialty Chemicals
and Polyurethane Chemicals. Emphasis is on chemicals and services for the
semiconductor industry where rapid technology change is creating more and more
opportunities for growth. We intend to build on our market and technology
leadership to take advantage of these opportunities.

FINANCIAL RESULTS

         Earnings from continuing operations were $24.7 million, or $1.27 per
share, including special items of 29 cents per share primarily from a gain on
the sale of former equity affiliate Power Sources, Inc.

         Results were disappointing following record chemical sales and earnings
last year. However, we made good progress positioning the company in key markets
for future growth. The new Baytown, Texas, aniline facility came on line in
April as planned and operated above design capacity by year end. We introduced
second-generation CMP products for customer trials, established research and
development and production facilities in Japan, and added production capability
for ultra-pure electronic chemicals. The deep ultraviolet (DUV) resins business
acquired last year was profitable and is growing.

CAPITAL EXPENDITURES

         CAPITAL EXPENDITURES FOR 1998 WERE $44 MILLION, PRIMARILY FOR
COMPLETION OF THE WORLD SCALE ANILINE FACILITY LOCATED AT BAYER CORPORATION'S
BAYTOWN CHEMICAL COMPLEX. THIS PLANT MORE THAN DOUBLED OUR ANILINE CAPACITY. A
PLANNED SECOND PHASE WILL ADD ANOTHER 250 MILLION POUNDS AND WILL BRING TOTAL
ANILINE CAPACITY TO ABOUT 740 MILLION POUNDS WHEN COMPLETED.

         CAPITAL EXPENDITURES IN 1999 WILL BE ONLY ABOUT $30 MILLION FOLLOWING
RECORD EXPENDITURES OVER THE PAST THREE YEARS THAT INCREASED PRODUCTION CAPACITY
IN MAJOR PRODUCT LINES 40% TO 100%. CAPITAL PROJECTS IN 1999 WILL BE PRIMARILY
FOR LAB EQUIPMENT AND PRODUCTION IMPROVEMENTS IN ELECTRONIC CHEMICALS,
MAINTENANCE AND PROCESS AND PRODUCTION IMPROVEMENTS IN OTHER AREAS, AND
COMPLETION OF AN ENTERPRISE RESOURCE PLANNING SYSTEM TO UPGRADE AND INTEGRATE
INFORMATION SYSTEMS.

         We do not anticipate major acquisitions. Our focus has been and
continues to be on product-line and technology acquisitions that build on and
extend our existing base of products and technologies. 

FINANCIAL STRUCTURE

         The balance sheet is strong. Debt is 20% of total capitalization. This
is below our long-term target of 35% and the 36% average of peer companies.

         Our former subsidiary Getchell Gold has agreed to merge with Placer
Dome. This will accelerate repayment of a $29 million note to the company.
Following receipt of this repayment and cash from the planned dispositions of
Steel and Engineered Products, financial leverage will decrease further. Excess
cash will be used to reduce debt and repurchase stock and to make product line
and technology acquisitions that complement and extend our existing businesses,
given the right opportunity.

         We spent nearly $43 million to repurchase 1.8 million shares of
ChemFirst stock in 1998 and are now working on an additional $50 million
repurchase authorization. We believe stock repurchases are a tax efficient way
to return value to shareholders when other attractive investment opportunities
are not available. 

ELECTRONIC AND OTHER SPECIALTY CHEMICALS

         ChemFirst is the global market leader in advanced cleaners for
back-end-of-the-line high-value applications in semiconductor production. Sales
volume of our HDA(R)products was up 15% for the year in spite of problems in the
semiconductor industry, which experienced a 4% decline in silicon acreage and a
drop in use of semiconductor materials of nearly 8%. In 1999 silicon acreage
growth is projected at 2% and materials growth at 6%. We should benefit from
this growth and from new product introductions.

         During the year we completed an applications lab in Japan to service
semiconductor manufacturers in this market. Japan represents approximately 40%
of the global market for cleaners and removers. Our current market share there
is relatively small. So we view Japan as a growth opportunity.

         Growing use of DUV photolithography and CMP is being driven by the
industry shift to smaller feature sizes and increased chip complexity. Chip
geometry is moving from 0.25 to 0.18 micron about 18 months ahead of the
semiconductor industry roadmap.

THIS REQUIRES ADVANCED DUV PHOTOLITHOGRAPHY. WE ARE THE LARGEST SUPPLIER OF DUV
PHOTORESIST RESINS INTO THIS RAPIDLY GROWING GLOBAL MARKET.

         CMP MARKETS ARE ALSO GROWING. THE PLANARIZED SURFACES CREATED BY CMP
PERMIT SHORTER WAVELENGTH, HIGH-RESOLUTION DUV LITHOGRAPHY REQUIRED FOR THE
SMALLER GEOMETRIES OF HIGHER PERFORMANCE CHIPS.

         OTHER SPECIALTY CHEMICALS INCLUDE PRODUCTS FOR PHARMACEUTICAL,
AGRICULTURAL, POLYMER, PHOTOGRAPHIC, AND PHOTOSENSITIVE APPLICATIONS. WE TAKE
PRODUCTS FROM RESEARCH AND DEVELOPMENT THROUGH COMMERCIAL PRODUCTION FOR BOTH
PROPRIETARY AND CUSTOM CHEMICALS. OUR STRATEGY IS TO IDENTIFY AND CAPITALIZE ON
GROWTH OPPORTUNITIES IN NICHE MARKETS FOR PROPRIETARY PRODUCTS AND PRODUCTION
PROCESSES. WE ARE THE ONLY U.S. PRODUCER OF MANY NITROTOLUENES AND DERIVATIVES.
ALTHOUGH MANY MARKETS FOR THESE PRODUCTS ARE MATURE, THIS IS A GOOD NICHE FOR US
BECAUSE OF OUR UNIQUE SUPPLY POSITION. MARKET CONDITIONS PROMPTED PRICE CUTS TO
PROTECT SUPPLY POSITIONS IN 1998. WE HOPE FOR MORE STABLE PRICES IN 1999, BUT
WILL CONTINUE TO DEFEND OUR MARKET SHARE.

POLYURETHANE CHEMICALS    

        Aniline production is back on track following first-half production
problems and a third-quarter hurricane at Pascagoula. The Baytown aniline plant
started up in March 1998 and is running near design capacity. Demand is good,
and we expect to operate at full rate in 1999 with a substantial increase in
revenues and earnings. We are the industry's largest merchant producer of
aniline.

        Cash flow from this business is greater than reinvestment opportunities
except for intermittent large projects. We view it as a source of funds for
growth in other areas.

OUTLOOK

        Although the first half will probably be weaker than last year, we
expect the year to be better helped by increased aniline and electronic chemical
sales. A 10% workforce reduction and other cost cuts, which amounted to about 5%
of total fixed costs, will also help 1999 results. This may be offset to some
degree by slightly higher interest expense and possibly some below-the-line
expenses associated with discontinued businesses.

ELECTRONIC AND OTHER SPECIALTY CHEMICALS

        THE COMPANY PRODUCES CHEMICALS FOR USE IN THE MANUFACTURE OF
SEMICONDUCTOR CHIPS AND FOR AGRICULTURAL, PHARMACEUTICAL, POLYMER, AND
PHOTOSENSITIVE APPLICATIONS. OBJECTIVES ARE TO DEVELOP AND MARKET PROPRIETARY,
HIGH-VALUE SPECIALTY CHEMICALS AND TO PROVIDE RESEARCH AND SCALE-UP PRODUCTION
FOR CUSTOMER PROCESSES. 

ELECTRONIC CHEMICALS

        THE COMPANY PRODUCES ORGANIC PHOTORESIST REMOVERS, POST-DRY-ETCH POLYMER
REMOVERS, DEEP ULTRAVIOLET RESINS FOR PRODUCTION OF PHOTORESISTS, AND OTHER
PERFORMANCE CHEMICALS AND MATERIALS FOR CLEANING AND POLISHING SILICON WAFERS IN
SEMICONDUCTOR MANUFACTURING. PRODUCTS ARE SOLD ON THE BASIS OF PRODUCT FUNCTION,
PURITY, AND CLEANNESS. THE COMPANY'S APPLICATIONS ENGINEERS WORK CLOSELY WITH
CUSTOMERS TO DEVELOP UNIQUE CHEMICAL SOLUTIONS TO ADVANCED SEMICONDUCTOR
MANUFACTURING ISSUES. PRODUCT PERFORMANCE, APPLICATIONS ENGINEERING SUPPORT, AND
SERVICE ARE KEY TO CUSTOMER SATISFACTION AND COMPETITIVE ADVANTAGE.

        Semiconductor growth is being driven by the increasing use of personal
computers and the proliferation of other electronic devices such as digital
television, digital cameras, and wireless communications; by the growing
acceptance of Internet applications and Web TV; and by the need to increase
device performance, speed, and capacity. In addition, new products containing
logic devices are being developed and introduced routinely for an increasing
number of office, home, and automotive applications. All of these devices
require high performance integrated circuits.

REMOVER PRODUCTS

        The company is the world's largest supplier of post-dry-etch polymer
removers and the second largest supplier of photoresist removers. Production
facilities and applications engineering labs in Hayward, California; East
Kilbride, Scotland; and Kawasaki-City, Japan, are strategically located near key
regional semiconductor production centers. Patented HDA(R) polymer removers
effectively remove residues formed during dry etching of silicon wafers and
continue to be the fastest-growing products in the history of the company. They
increase yields and improve chip performance, which translates into lower costs
and higher margins for chip manufacturers. This technology has established the
company as a leader in the electronic chemicals industry.

CHEMICAL MECHANICAL PLANARIZATION (CMP)

        In January 1998, the company entered the CMP market through two
product-line acquisitions. These acquisitions provided ChemFirst with CMP
technologies, products and customers, slurry manufacturing equipment,
applications labs, and exclusive supply positions for proprietary powders and
abrasives used in CMP slurries.

During the year, the company introduced new proprietary remover products that
facilitate the use of advanced copper interconnects for tomorrow's semiconductor
devices. These products permit cleaning of copper without corrosion or surface
etching while maintaining compatibility with low-k dielectric materials.

        CMP IS RAPIDLY BECOMING AN ESSENTIAL SEMICONDUCTOR PROCESS FOR THE
PRODUCTION OF ADVANCED LOGIC AND MEMORY DEVICES. THE CMP PROCESS INVOLVES
POLISHING THE OXIDE (INSULATING) LAYERS AND THE METAL (CONDUCTOR) LAYERS DURING
SEMICONDUCTOR FABRICATION USING A SLURRY OF ABRASIVES AND CHEMICALS TO PRODUCE A
FLAT OR PLANARIZED SURFACE. FLATTER SURFACES ENABLE THE USE OF SHORTER
WAVELENGTH, HIGH-RESOLUTION LITHOGRAPHY SUCH AS THE NEW DEEP ULTRAVIOLET (DUV)
LITHOGRAPHY TO CREATE THE SMALLER LINE-WIDTH GEOMETRIES NEEDED FOR FUTURE
GENERATIONS OF SMALLER, HIGHER PERFORMANCE, AND FASTER INTEGRATED CIRCUITS. THE
COMPANY'S FOCUS IS ON DEVELOPING PRODUCTS AND MATERIALS FOR METAL CMP
APPLICATIONS AND POST-CMP CLEANING.

        Several leading semiconductor manufacturers have announced major
programs to advance the use of copper as an interconnect layer using a new
inlaying or damascene process. Chips made using the damascene process are
faster, less expensive, and more energy efficient than chips made with
conventional processes. Copper damascene processing requires metal CMP.

DEEP ULTRAVIOLET (DUV) RESINS

        The company supplies DUV resins to photoresist manufacturers for
production of DUV photoresist used in leading edge manufacture of semiconductor
chips.

        In DUV photolithography, a thin film of DUV photoresist is applied to a
highly polished, ultra-pure silicon wafer. This film is then exposed to DUV
light through a pattern mask followed by development, ion implantation, etching,
and other procedures. This processing sequence creates single-layer circuit
tracings onto a wafer and is repeated as necessary to ultimately achieve the
complex, multi-layer circuitry of finished semiconductors.

        Growing use of DUV photolithography in semiconductor production is
driven by the trend toward smaller chip geometry for increased productivity
(number of chips per wafer). Smaller design geometries with feature sizes below
0.25 micron are achieved by using DUV photolithography. The company currently is
the largest supplier of products to the global DUV photoresist resin market.

OTHER SPECIALTY CHEMICALS

        The company manufactures specialty chemicals using both proprietary and
customer technology. Markets include agricultural, pharmaceutical, polymer,
photographic, dye and pigment and photosensitive applications.

printing inks, varnishes, lacquers, and adhesives. The photo curing process
utilizes ultraviolet light to convert liquid coatings or inks into a dry or
"cured" film. These products are energy efficient, have shorter curing cycles,
are more environmentally friendly than traditional processes, and create a
higher-quality, more durable finish. The company also produces chemicals for
pharmaceuticals, including protease inhibitors used in the treatment of AIDS,
and other chemical applications such as in herbicides, rubber processing
chemicals, photographic chemicals, optical brighteners, and dyestuffs and
pigments.

POLYURETHANE CHEMICALS

        The company is a major producer of aniline and nitrobenzene, with world
scale plants and long-term supply relationships with major chemical companies.
These products are produced in efficient, continuous process facilities.

        Aniline is the company's largest product. Approximately 75% of aniline
produced in the U.S. is used to manufacture MDI (methylene diphenyl
diisocyanate) used in polyurethane foams and in urethane elastomers used in
automobile body components. Other significant markets for aniline include tire
and agricultural chemicals and plastics for consumer goods.

        The company currently supplies all of Bayer Corporation's North American
aniline requirements under long-term contract from plants in Pascagoula,
Mississippi, and Baytown, Texas.


THE COMPANY RECENTLY ESTABLISHED CUSTOM CHEMICAL SERVICES CAPABILITY FOR

        NITROBENZENE IS USED TO MAKE ANILINE AND IS SOLD SEPARATELY FOR THE
MANUFACTURE OF PHARMACEUTICALS, RUBBER CHEMICALS, AND AGRICULTURAL CHEMICALS.

        ANILINE AND NITROBENZENE ARE SOLD IN BULK AND DISTRIBUTED BY RAIL, 
TRUCK, BARGE, AND SHIP DEPENDING ON THE SIZE AND DESTINATION OF THE SHIPMENT.

        DURING THE YEAR, THE COMPANY COMPLETED CONSTRUCTION AND STARTED
PRODUCTION OF THE WORLD SCALE, 250-MILLION-POUND-PER-YEAR ANILINE FACILITY
LOCATED AT BAYER'S BAYTOWN, TEXAS, CHEMICAL COMPLEX. THE FACILITY IS AN INTEGRAL
PART OF BAYER'S U.S. MDI MANUFACTURING OPERATIONS. THIS PLANT, PHASE I OF A
TWO-PHASE PROJECT, MORE THAN DOUBLED THE COMPANY'S ANILINE CAPACITY. A PLANNED
SECOND PHASE WILL ADD ANOTHER 250 MILLION POUNDS OF CAPACITY, BRINGING TOTAL
ANILINE CAPACITY TO APPROXIMATELY 740 MILLION POUNDS WHEN COMPLETED.

RESEARCH AND DEVELOPMENT

        R&D activities identify new markets and applications, new and improved
process technologies, and new products. Applied research is sponsored at several
leading universities in the United States and Europe to complement in-house
efforts. University research programs have led to the successful development and
introduction of patented semiconductor wafer cleaners and performance polymers.

        The focus of R&D spending in 1998 was primarily on electronic chemicals,
including new CMP products for tungsten and copper applications and DUV resins
development for new photoresists. The company is working with new low-k
materials suppliers to develop chemistries and processes for these new materials
and with etch equipment manufacturers to develop removers for their new etch
recipes. Joint development and cooperative agreements with major semiconductor
equipment suppliers, materials suppliers, and key customers are leading to the
development of chemical solutions for problems related to the production of next
generation chips.

<PAGE>   18

MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

        In June 1997, Statement of Financial Accounting Standards (SFAS) No.
131, Disclosures about Segments of an Enterprise and Related Information, was
issued, to be effective for fiscal years beginning after December 15, 1997. This
statement mandates a management approach, based on the way management organizes
businesses within a company for making operating decisions and assessing
performance, to provide selected reporting information. The following discussion
is based upon and should be read in conjunction with the selected historical
financial information and the Company's financial statements, including the
notes thereto, which reflect the adoption of this statement.

        1998 VERSUS 1997

        CONSOLIDATED RESULTS

        Income from continuing operations for 1998 was $24.7 million, down 35%
from the prior year. Results for 1998 include other income of $9.3 million ($5.7
million after tax), primarily related to the gain on the sale of the Company's
50% interest in Power Sources, Inc. (PSI) in the first quarter of 1998. Prior
year results include a $14.7 million gain ($8.8 million after tax) from the
fourth quarter sale of the Companys 23% interest in Melamine Chemicals, Inc.
(Melamine) and $2.5 million equity in net earnings of PSI and Melamine (see note
3 to the Consolidated Financial Statements). Excluding these gains and equity
earnings, earnings from continuing operations were $19.0 million, down 28% from
$26.5 million in 1997 primarily due to lower margins, increased research and
development and higher interest expense. Sales for the year were up 2%,
primarily due to higher aniline volume.

        SEGMENTS

        Electronic and Other Specialty Chemicals pretax operating profits for
1998 were $17.8 million on sales of $179.6 million. Sales of chemical mechanical
planarization and acylation derivatives products (used primarily in the
manufacture of integrated circuits) from acquisitions in December 1997, were
$14.9 million and pretax operating losses were $2.6 million. Pretax operating
profits and sales, excluding the above acquisitions, were down 26% and 8%,
respectively, due to lower demand for an agricultural chemical intermediate and
lower prices from many products due to competitive pressure. Remover product
sales volume was up 4% and average unit prices were unchanged despite an
estimated 4% decline in worldwide silicon consumption and a downturn in the
semiconductor industry.

        Polyurethane Chemicals pretax operating profits were $22.6 million, down
6% from the prior year. Operating profits declined in 1998 as lower production
and higher costs at the Pascagoula, Mississippi, facility and 17% lower average
nitrobenzene prices more than offset the additional production from the Baytown,
Texas, facility. Sales for the year were $125.5 million, up 6% as a 16% increase
in sales volume was partially offset by lower average sales prices. The
increased volume was due to the added production from the Companys new
250-million-pound-per-year aniline facility in Baytown, which began operations
in March 1998. The additional Baytown production was partially offset by reduced
aniline production at Pascagoula mostly due to production inefficiencies and
unscheduled plant maintenance in the first quarter and a scheduled plant
turnaround in the second quarter. Hurricane Georges struck the Pascagoula
facility on September 28, 1998, and shut down operations for 18 days. However,
the Companys insurance will cover most of the facility's repairs and lost 
profits incurred during that period.

        Unallocated corporate expenses for 1998 were $9.8 million, down 14% from
the prior year primarily due to a reduction in compensation expense indexed to
the Companys stock price. Net interest income was down $2.8 million due to $1.7
million in higher interest expense, net of capitalized interest, and $1.1
million in lower interest income. Capitalized interest for the year was up $0.8
million over the prior year. Interest expense was up on higher debt while
interest income declined as cash proceeds received in 1996 from the fertilizer
disposition were used for capital expenditures and share repurchases. Other
income and expense in 1998 included a $10.1 million gain on the sale of PSI and
a $0.8 million valuation allowance for a note received in the disposition of
Plasma Processing Corporation in January 1997. Other income for 1997 included
the $14.7 million gain on the sale of Melamine.

        1997 VERSUS 1996

        CONSOLIDATED RESULTS

        Income from continuing operations for 1997 was $37.8 million versus
$17.0 million for 1996. Results for 1997 include a $14.7 million ($8.8 million
after tax) gain from the sale of Melamine. Excluding this gain and equity
earnings, income from continuing operations for 1997 was $26.5 million, up 64%
from 1996 on a 21% increase in sales and lower interest expense. Interest
expense for 1997 was down $6.3 million from the prior year due to the
extinguishment of most debt of the company with the disposal of fertilizer
operations in December 1996 (see note 2 to the Consolidated Financial
Statements).

        SEGMENT OPERATIONS

        Electronic and Other Specialty Chemicals operating profits for 1997 were
$27.6 million, up 23% from 1996 as sales grew 19%. The increase in sales was due
to high utilization of capacity expansions completed in December 1996 and
increased nitrotoluene derivative sales volume.

        Polyurethane Chemicals pretax operating profits for 1997 were $24.1
million, up 14% from 1996 as sales increased 24% primarily due to higher sales
volumes. Nitrobenzene sales volume was up due to increased production following
modifications at the Pascagoula facility. Aniline sales volume was up 16%,
primarily due to the purchase of product for resale. However, these aniline
sales did not contribute significantly to operating results.

        Unallocated corporate expenses for 1997 were $11.3 million, down 15%
from 1996, which included $1.0 million in corporate expenses related to the
companys name change and restructuring in association with the disposition of
fertilizer operations. Net interest income was $3.0 million in 1997 versus a net
interest expense of $3.9 million in 1996, primarily due to the assumption of
debt by Mississippi Chemical Corporation related to the disposal of fertilizer
in December 1996 and higher interest income from the invested cash proceeds of
the transaction. Other income for 1997 included the $14.7 million gain on the
sale of Melamine.

        DISCONTINUED OPERATIONS

        In the fourth quarter of 1998, the Company's board of directors approved
a plan to dispose of Callidus Technology, Inc. (CTI). The plan assumes this
disposition will be finalized during 1999. CTIs net book amount at December 31,
1998, was $15.6 million. The disposal of CTI, which includes Plasma Energy
Corporation, will complete the disposition of the Engineered Products and
Services segment. The disposition of the other major portion of this segment,
Plasma Processing Corporation, was completed in January 1997.

        In the third quarter of 1998, the Company finalized plans to dispose of
its steel operations by the end of 1999. An anticipated loss on disposal of
$12.0 million, net of applicable income taxes of $6.0 million, was recorded at
September 30, 1998, and was primarily related to the writedown of assets to
their estimated net realizable value. As of December 31, 1998, the proceeds of
this disposal, including income tax benefit, are estimated to be approximately
$27.0 million. During the year, the U. S. steel industry was hurt by imports and
by a weak domestic market. This led to a sharp decline in steel orders and
margins. The Company believes these conditions have also negatively affected
disposition of the steel operations.

        On December 24, 1996, First Mississippi completed the spinoff of
ChemFirst Inc. and the combining of its fertilizer operations with Mississippi
Chemical Corporation. On October 20, 1995, the Company completed the spinoff of
its 81% owned subsidiary, Getchell Gold Corporation (Getchell), to shareholders.
In November 1998, Getchell and Placer Dome Inc. announced plans to merge.
Closing is anticipated in the second quarter of 1999 and, if consummated, will
result in the prepayment of approximately $29.3 million of principal and
interest due to the Company.

<PAGE>   20
        The historical results of the above businesses, the gain on disposal of
fertilizer operations and the estimated loss on disposal of steel operations,
are reflected in discontinued operations.

        Loss from discontinued operations for 1998 was $2.6 million versus
earnings of $1.1 million and $9.1 million in 1997 and 1996, respectively. The
loss in 1998 was primarily in steel operations. The earnings in 1996 included
$36.6 million in earnings from fertilizer operations, partially offset by $27.5
million in total losses in steel and engineered products and services
operations. Engineered products and services losses in 1996 were primarily due
to write-downs and accruals made in anticipation of the sale of aluminum
recovery operations. In 1998, the Company recorded a net loss from disposal of
steel operations of $12.0 million. The gain on disposal of businesses in 1996
includes $225.4 million in gain from the disposal of fertilizer operations, net
of $1.7 million in losses related to operations discontinued in prior years (see
notes 1 and 2 to the Consolidated Financial Statements for the details of these
transactions).

        ENVIRONMENTAL MATTERS

        The Company's operations are subject to a wide variety of constantly
changing environmental laws and regulations governing emissions to the air,
discharges to water sources, and the handling, storage, treatment and disposal
of waste materials, as well as other laws and regulations concerning health and
safety conditions for which it must incur certain costs. The Companys capital
expenditures for environmental protection were $0.2 million in 1998. Capital
expenditures are projected to be $1.4 million and $1.1 million for 1999 and
2000, respectively. In addition, the Company accrues for anticipated costs
associated with investigatory and remediation efforts relating to the
environment. At December 31, 1998, the Companys accrued liability for these
matters totaled $1.6 million, $1.4 million of which is for discontinued
operations and $0.2 million for continuing operations. Based on information
presently available, the Company believes any amounts paid in excess of the
accrued liabilities will not have a material adverse effect on its financial
position, cash flows or results of operations.

        In October 1996, the American Institute of Certified Public Accountants
issued Statement of Position 96-1, Environmental Remediation Liabilities. This
statement provides guidance in applying existing accounting literature to
calculating, recording and disclosing environmental remediation liabilities. The
adoption of this standard did not have a material effect on the Company's 1997
or 1998 financial statements.

        CAPITAL RESOURCES AND LIQUIDITY

        Net cash provided by operations was $34.2 million, up $10.6 million from
1997. Net cash provided by operating activities in 1997 was lower, primarily due
to the reduction of accruals made in 1996 related to the fertilizer disposition.
Investing activities for the year included pretax proceeds of $19.0 million from
the sale of PSI and $43.8 million in capital expenditures. Capital expenditures
were down versus 1997 when the bulk of expenditures for the new aniline facility
in Baytown and expenditures for specialty chemical expansions in Pascagoula were
made. Financing activities for 1998 included $42.6 million for the repurchase of
Company stock and $46.4 million in net borrowings.

        Projected capital expenditures for 1999 are approximately $30.0 million.
Also, the Company has approximately $48.0 million remaining in its current stock
repurchase plan. The Company believes that its cash flow from operations,
combined with access to its existing or additional bank credit facilities,
adequately provide for the Companys cash requirements. Additional anticipated
sources of cash include proceeds related to discontinued operations, including
the disposal of its steel operations and CTI, plus collection of a note due from
Getchell (see Discontinued Operations).

        RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

        In March 1998, the Accounting Standards Executive Committee (AcSEC)
released Statement of Position (SOP) 98-1, Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use. The SOP identifies the
characteristics of internal-use software and provides guidance for accounting
treatment of costs for computer software developed or obtained for internal use
as related to capitalization or expense decisions. The statement is effective
for fiscal years beginning after December 15, 1998. In April 1998, AcSEC
released SOP 98-5, Reporting on the Costs of Start-Up Activities. The SOP
broadly defines start-up activities and provides guidance on the financial
reporting of start-up costs and organization costs. It requires costs of
start-up activities and organization costs to be expensed as incurred. The
statement is effective for fiscal years beginning after December 15, 1998.
Adoption of these statements is not expected to have a material impact on the
Companys financial statements.

        SFAS No. 133, Accounting for Derivative Instruments and Hedging
Activities, was issued in June 1998, effective for fiscal years beginning after
June 15, 1999. The statement establishes accounting and reporting standards for
derivative instruments and for hedging activities. All derivatives are required
to be recognized as either assets or liabilities in the statement of financial
position and measured at fair value. Changes in fair value will be reported
either in earnings or outside earnings depending on the intended use of the
derivative and the resulting designation. Entities applying hedge accounting are
required to establish at the inception of the hedge the method used to assess
the effectiveness of the hedging derivative and the measurement approach for
determining the ineffective aspect of the hedge. The Company currently follows
SFAS No. 52, Foreign Currency Translation, and applies hedge accounting
treatment to certain foreign currency transactions by entering into forward
exchange contracts. Gains and losses associated with currency rate changes on
forward contracts hedging foreign currency transactions are recorded in income
and generally offset the transaction losses or gains on the foreign currency
cash flows that they are intended to hedge. Gains and losses on contracts
hedging firm sales commitments are deferred until the related transactions are
consummated. The Company has not completed its analysis of SFAS No. 133 and,
accordingly, has not determined what effect, if any, it may have on future
operations and financial statement disclosure.

        MARKET RISK

        The Company is exposed to changes in financial market conditions in the
normal course of its business, including changes in interest rates and foreign
currency exchange rates. At December 31, 1998, the Companys derivative and other
financial instruments included long-term debt denominated in U.S. dollars and
short-term debt denominated in Japanese yen and a series of short-term forward
sales of Japanese yen. Due to the short-term nature and size of these yen
obligations, the Company does not consider its exposure to foreign currency or
interest rate fluctuations on these instruments to be material.

        The Company utilizes fixed and variable-rate debt to maintain liquidity
and fund its business operations, with the terms and amounts based on business
requirements, market conditions and other factors. At December 31, 1998, the
market value of the Company's fixed rate borrowings was approximately $24.0
million. A 100 basis point change in interest rates (all other variables held
constant) as of December 31, 1998, would result in a $1.0 million change in fair
market value, but would not affect interest expense or cash flow. At December
31, 1998, the Company had $41.0 million in variable-rate debt. A 100 basis point
change in interest rates (all other variables held constant) on this portion of
the Company's debt, would result in a change in interest expense of
approximately $0.4 million.

        YEAR 2000

        The advent of the Year 2000 poses significant risks to many companies
because of calculation limitations imposed by some equipment and systems limited
to storing a year as a two-digit field (e.g., 1998 as 98), which may lead to
computational errors when the years 2000 or later are used in calculations. In
1996, the Company began a study which led to the purchase in 1997 of a
company-wide Enterprise Resource Planning (ERP) system to integrate the
Company's information systems, replacing small, stand-alone purchased systems.

<PAGE>   22
        The ERP system will be Year 2000 compliant, with the material portion of
the system planned for completion by the middle of 1999. Installation is being
completed in stages, with the first sites converted at December 31, 1998. To
date, the Company has spent $8.9 million on this project and is projecting to
spend approximately $2.0 million in 1999. If difficulties are encountered that
delay the ERP system implementation, contingency plans provide for the purchase
of select, Year 2000 compliant personal computer software products, the cost of
which should not be material.

        A corporate-wide survey of other information technology (IT) and non-IT
equipment and systems utilizing date or time functions has been undertaken. The
current estimated cost to remediate is less than $0.6 million, most of which
will be incurred in 1999. Remediation, including verification testing of most
non-compliant systems, equipment and software is targeted for completion by
April 30, 1999. Some remediations at the Pascagoula facility, however, will
occur in the fourth quarter of 1999 to coincide with the next scheduled plant
maintenance turnaround. Contingency plans are currently being developed in the
event the remediations do not occur or are delayed. Severe delay or widespread
failure affecting both the remediation effort and the contingency plans,
although not expected, could have a material effect on the Company's financial
condition and results of operations.

        Key customers, as well as service and raw material suppliers, are being
surveyed about their Year 2000 readiness. Depending on their responses,
contingency plans will be developed as appropriate. It is anticipated that this
process will be completed no later than September 30, 1999. Although the Company
cannot quantify the precise effect, significant or prolonged disruptions of key
customers or suppliers could have a material effect on the Companys financial
condition and results of operations. For example, the majority of aniline
produced by the Company is sold through long-term contracts to a few customers.
Their inability to utilize the Company's aniline could have a material adverse
effect.

        FORWARD-LOOKING STATEMENTS

        Certain statements included in this Managements Discussion and Analysis
of Financial Condition and Results of Operations that relate to the Year 2000,
proceeds from the discontinuance of steel and engineered products and services
operations, the prepayment of a note by Getchell and insurance recoveries
related to recent hurricane damage, as well as other statements in this Annual
Report that are not historical in nature, may constitute forward-looking
statements within the meaning of the Private Securities Litigation Reform Act of
1995. Such forward-looking statements, as well as other forward-looking
statements made from time to time by the Company or in the Company's press
releases and filings with the U.S. Securities and Exchange Commission, are based
on certain underlying assumptions and expectations of management.

        These forward-looking statements are subject to risks and uncertainties
which could cause actual results to differ materially from those expressed in
such forward-looking statements. Such risks and uncertainties include, but are
not limited to, general economic conditions, availability and pricing of raw
materials, supply/demand balance for key products, new product development,
manufacturing efficiencies, conditions of and product demand by key customers,
the timely completion and start up of construction projects, pricing pressure as
a result of the downturn in markets, successful installation of the Company's
new ERP system, the inability of the Company to either resolve the Companys Year
2000 issues or to accurately estimate the costs associated with Year 2000
compliance, the resolution of contingencies related to the sale of PSI,
insurance coverage related to hurricane damage to the Company's Pascagoula
facility and other factors as may be discussed in the Company's Form 10-K for
the fiscal year ended December 31, 1998.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

DECEMBER 31, 1998, 1997 AND 1996

(In thousands of dollars, except share data; disclosures included in the Notes
to Consolidated Financial Statements relate to continuing operations, unless
otherwise indicated.)

1.      BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

        CHANGE IN ORGANIZATION

        ChemFirst Inc. (the Company) was incorporated in Mississippi in 1983
under the name, Omnirad, Inc., as a wholly owned subsidiary of First Mississippi
Corporation (First Mississippi). In November 1996, in anticipation of the
Distribution (as described below), the Companys name was changed from Omnirad,
Inc. to ChemFirst Inc.

        Prior to December 23, 1996, the Companys subsidiaries were subsidiaries
of First Mississippi and the Companys operations were conducted through
subsidiaries of First Mississippi. On December 23, 1996 (the Distribution Date),
First Mississippi contributed all of its assets and subsidiaries, other than
those relating to its fertilizer business, to the Company, which at that time
was a wholly owned subsidiary of First Mississippi and had engaged in no
operating activities during the previous five years. First Mississippi then spun
off the Company in a tax-free distribution of the Companys common stock to First
Mississippi shareholders (the Distribution) on the Distribution Date. The
Distribution occurred immediately prior to and in connection with the merger of
First Mississippi with a wholly owned subsidiary of Mississippi Chemical
Corporation (MCC), pursuant to an Agreement and Plan of Merger and
Reorganization dated as of August 27, 1996 (the Merger). The Company has
operated as a publicly held entity since the Distribution Date. For financial
reporting purposes, this transaction has been accounted for as a disposal of the
fertilizer business. Accordingly, the Companys financial statements prior to the
Distribution are the historical financial statements of First Mississippi
restated to present the fertilizer business as a discontinued operation. For
further information, see note 2.

        BASIS OF PRESENTATION

        The principal businesses of the Company involve the production of
electronic and other specialty chemicals for use in the semiconductor industry
and in agricultural, pharmaceutical, polymer, photographic and photosensitive
applications, as well as the production of polyurethane chemicals. Further
descriptions of the Companys products and the relative significance of its
operations are included in the segment information data in note 12.

        The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates. Material
estimates that are susceptible to significant change in the near term relate to
the estimated losses and timing of discontinuation and disposal of businesses.

        PRINCIPLES OF CONSOLIDATION

        The consolidated financial statements include the accounts of the
Company and its subsidiaries. Intercompany balances and transactions have been
eliminated in consolidation. Investments in equity investments are accounted for
by the equity method.

        RECOGNITION OF REVENUE

        Revenues generally are recorded when title and risk of ownership pass
except for long-term construction-type contracts of certain discontinued
operations, which are accounted for under the percentage of completion method.

        INVENTORIES

        Inventories are stated at the lower of cost or market. Cost is
determined using the first-in, first-out and weighted average methods.



10
<PAGE>   28
        INTANGIBLE ASSETS

        Intangible assets are reviewed for impairment when the facts and
circumstances indicate that the carrying amount may not be recoverable.

        DEPRECIATION AND AMORTIZATION

        Depreciation of plant and equipment and depreciable investments is based
on cost and the estimated useful lives of the separate units of property. The
straight-line method is used in determining the amount of depreciation charged
to expense. Goodwill of businesses acquired is generally amortized up to 20
years using the straight-line method. Other intangibles are amortized over their
estimated useful lives (5-17 years) using the straight-line method.

        Loan costs are amortized over the terms of related loans using the
interest method.

        PENSION PLANS

        Pension cost is determined using the projected unit credit actuarial
method for financial reporting purposes. The Companys funding policy is to
contribute annually at amounts not less than the minimum requirements of the
Employee Retirement Income Security Act of 1974.

        INCENTIVE COMPENSATION

        All outstanding stock options are nonqualified and require no charges to
expense upon grant or exercise. The tax benefit the Company receives from
dispositions that result in ordinary income to option recipients is included in
stockholders equity.

        Phantom share units require no charge to expense upon grant or
redemption except that compensation plan discounts are amortized to expense over
various holding periods of up to three years. The share units are credited with
equivalent dividends equal to cash dividends paid by the Company. Equivalent
dividends are expensed through the statement of operations.

        CASH AND CASH EQUIVALENTS

        The Company considers all short-term investments with original
maturities of three months or less to be cash equivalents.

        INVESTMENTS

        Realized gains and losses on investments are determined on the basis of
specific costs.

        CONTINGENCIES

        Estimates of loss contingencies, including environmental liability costs
for remediation, are charged to expense when it is probable an asset has been
impaired or a liability incurred and the amount can be reasonably estimated. If
a potentially material loss contingency is reasonably possible, or probable but
cannot be estimated, then the nature of the contingency and an estimated range
of possible loss, if determinable and material, are disclosed.

        FOREIGN CURRENCY TRANSLATION

        Financial statements of foreign subsidiaries are translated into U.S.
dollars at current rates, except that revenues, costs and expenses are
translated at average current rates during each reporting period. Net exchange
gains or losses resulting from the translation of foreign financial statements
and the effect of exchange rate changes on intercompany transactions of a
long-term investment nature are accumulated in other comprehensive income.




                                                                              11

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS CONTINUED

        DERIVATIVE FINANCIAL INSTRUMENTS        

        The Company uses forward exchange contracts to hedge certain foreign
receivables and firm sales commitments to be denominated in currencies other
than the functional currency of the entity involved. The contracts are
designated and effective as hedges. Gains and losses on contracts that hedge
recorded receivables activity offset the exchange rate fluctuations of the
underlying hedged transaction. Accounting for gains and losses on contracts
designated as hedges of identifiable foreign currency sales commitments involves
deferring recognition until the related transactions are consummated. When
consummated, these gains and losses are recorded in net income (see note 15).

        ACCOUNTING CHANGES

        Statement of Financial Accounting Standards (SFAS) No. 121, Accounting
for the Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed of,
was adopted by the Company in 1996 with no material effect to the Company.

        SFAS No. 123, Accounting for Stock-Based Compensation, was adopted by
the Company in 1996. In accounting for employee stock options and similar equity
instruments, companies are given the choice of either recognizing related
compensation cost by adopting the fair value method, or to continue using the
intrinsic value method prescribed by Accounting Principles Board Opinion No. 25
(APB No. 25), Accounting for Stock Issued to Employees, and supplementally
disclose the proforma effect on earnings and earnings per share using SFAS No.
123 measurement criteria. The Company elected to continue to follow the
requirements of APB No. 25, and accordingly, there is no effect on the results
of operations.

        SFAS No. 128, Earnings per Share, was adopted by the Company in 1997.
This Statements objective is to simplify and standardize, relative to other
countries, the computation of earnings per share (EPS) previously required by
APB Opinion No. 15, Earnings per Share. It requires dual presentation of basic
and diluted EPS on the face of the income statement and a reconciliation of
basic and diluted EPS for continuing operations. Adoption of this Statement did
not have a material effect on the Companys EPS.

        SFAS No. 129, Disclosure of Information about Capital Structure, was
adopted by the Company in 1997 relative to descriptive disclosure of securities
outstanding. The Companys disclosure requirements are unchanged from previous
requirements.

        SFAS No. 130, Reporting Comprehensive Income, was adopted by the Company
in 1998. Its objective is to report all changes in equity during a period except
those resulting from investments by owners and distributions to owners. The
Company has presented comprehensive income detail in the consolidated statements
of stockholders equity.

        SFAS No. 131, Disclosures about Segments of an Enterprise and Related
Information, was adopted by the Company in 1998. Its objective is to report
segment information based on the way management organizes the segments within
the enterprise for making operating decisions and assessing performance. Segment
information has been presented on this basis.

        SFAS No. 132, Employers Disclosures about Pensions and Other
Postretirement Benefits, was adopted by the Company in 1998. The purpose of this
statement is to provide additional insight into benefit obligation and plan
asset changes.

<PAGE>   30
        FUTURE IMPACT OF RECENT ACCOUNTING PRONOUNCEMENTS

        SFAS No. 133, Accounting for Derivative Instruments and Hedging
Activities, was issued in June 1998, effective for fiscal years beginning after
June 15, 1999. The statement establishes accounting and reporting standards for
derivative instruments and for hedging activities. All derivatives are required
to be recognized as either assets or liabilities in the statement of financial
position and measured at fair value. Changes in fair value will be reported
either in earnings or outside earnings depending on the intended use of the
derivative and the resulting designation. Entities applying hedge accounting are
required to establish at the inception of the hedge the method used to assess
the effectiveness of the hedging derivative and the measurement approach for
determining the ineffective aspect of the hedge. The Company currently follows
SFAS No. 52, Foreign Currency Translation, and applies hedge accounting
treatment to certain foreign currency transactions by entering into forward
exchange contracts. Gains and losses associated with currency rate changes on
forward contracts hedging foreign currency transactions are recorded in income
and generally offset the transaction losses or gains on the foreign currency
cash flows that they are intended to hedge. Gains and losses on contracts
hedging firm sales commitments are deferred until the related transactions are
consummated. The Company has not completed its analysis of SFAS No. 133 and,
accordingly, has not determined what effect, if any, it may have on future
operations and financial statement disclosure.

2.      ACQUISITIONS AND DISPOSALS

        ACQUISITIONS

        On December 31, 1997, the Company acquired from Clariant Corporation an
acylation derivatives business involved in the development and marketing of
photoresist applications, as well as the chemical mechanical planarization
assets of Baikowski International Corporation and Moyco Technologies, Inc. The
aggregate purchase price of these three businesses was approximately $14,900,
including approximately $11,200 in cash and contingent consideration of
approximately $3,700 (approximately $5,000 face value before discounting),
payable in five years. Goodwill is amortized on a straight-line basis over the
period assigned to each acquisition, ranging from five to 15 years.

        DISPOSALS

        In the fourth quarter of 1998, the Companys board of directors approved
a plan to dispose of Callidus Technology, Inc. (CTI). The plan assumes this
disposition will be finalized during 1999. The assets and liabilities of CTI
have been classified, net, as current discontinued assets of $9,600 and
non-current discontinued assets of $6,000. With this disposal, the Company will
complete the disposition of its Engineered Products and Services segment. The
disposition of the other major portion of this segment, Plasma Processing
Corporation was completed in January 1997 with a sale for $4,100, generating no
gain or loss on disposal. The Company recorded pretax charges of $20,402,
($18,256 and $2,146 during the second and fourth quarters of 1996, respectively)
in anticipation of the sale. These charges included $13,941 in asset writedowns
and $6,461 in accruals, consisting of $4,146 in estimated costs in excess of
market value to process inventory to meet contractual obligations, $500 for
disposal of marketable inventory, $525 for severance and $1,290 for contract
cancellations and other estimated costs. In December 1998, an additional accrual
of $1,465 was made to dispose of unprocessed inventory. In 1998 and prior years,
the Company expended $888 and $5,598, respectively, in cash against these
accruals, primarily related to inventory processing and severance payments,
leaving an accrual balance of $1,440.

        In the third quarter of 1998, the Companys board of directors approved a
plan to discontinue its steel operations through a disposal of the assets of
FirstMiss Steel, Inc. by September 1999 and accordingly, the assets and
liabilities, net, have been classified as current. The carrying amount of these
assets was written down by $14,872 in the third quarter of 1998 to estimated net
realizable amount. In addition, accruals of $3,128 were recorded for estimated
costs of exiting this business. The carrying amount of the Steel net assets was
$26,565 at December 31, 1998. A previous writedown of $10,125 was taken in 1996.





                                                                              13

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS CONTINUED

        As discussed in note 1, on December 23, 1996, First Mississippi
completed the spinoff of the Company and on December 24, 1996, First Mississippi
and its fertilizer operations (Fertilizer) were merged with a wholly owned
subsidiary of MCC. Prior to the completion of the transaction, First Mississippi
borrowed $150,500, which was used to refinance First Mississippis existing
indebtedness and pay certain transaction costs. This debt remained the
obligation of First Mississippi, which became a subsidiary of MCC as a result of
the Merger. As part of the transaction, for each share of First Mississippi
common stock outstanding at the close of trading on December 23, 1996, First
Mississippi shareholders received one share of ChemFirst Inc. common stock and
approximately one-third share of MCC common stock. The total value of the
transaction was approximately $312,500, based on the value of the assumed
indebtedness of $150,500 and the value, approximately $162,000, of the shares of
MCC distributed to First Mississippi shareholders. These total proceeds, less
the net book value of the Fertilizer assets and related transaction costs,
resulted in a pretax gain of approximately $222,000 and an after tax gain of
approximately $225,000. The gain on disposition of the Fertilizer assets is
included in gain on disposal of businesses in the December 31, 1996,
consolidated statements of operations. The tax benefit from the transaction was
for certain tax deductible expenses incurred by the Company. The distribution of
MCC shares to First Mississippi shareholders is reported as a reduction of
stockholders equity in the accompanying December 31, 1996, financial statements.

        A pretax loss of $2,700 was also recorded during the year ended December
31, 1996, related to other previously discontinued businesses and is included in
gain on disposal of businesses, net of applicable income tax benefit of $954, in
the consolidated statements of operations. Such loss resulted from revised
estimates of environmental remediation costs and settlements of operating costs
related to previously discontinued phosphate fertilizer (1982) and oil and gas
(1993) businesses.

        The net assets and liabilities of discontinued operations included in
the consolidated financial statements are classified as current assets,
noncurrent assets and noncurrent liabilities by segment as follows:

        There were no compensating balance requirements under loan agreements in
effect at December 31, 1998. The above obligations mature in various amounts
through 2005, including $251 in 1999, $44,956 in 2002, $15,000 in 2003 and
$5,000 in 2005.

        In November 1998, the Company entered into a $20,000 private placement
of senior notes with two institutional investors. The Tranche A and B notes have
interest-only payments until October 30, 2003 and October 30, 2005, at interest
rates of 6.50% and 6.75%, respectively.

        The Company has a $100,000 bank revolving credit facility originating
June 1997, which is committed until May 2002. At December 31, 1998, there was a
balance of $41,000 outstanding under the facility at a weighted average rate of
5.85%. Outstanding letters of credit under the facility were $8,678, leaving
$50,322 available for borrowings. Interest rates are based on either the London
Interbank Offered Rate or the prime rate. A facility fee ranging from .125 to
..150 of 1% per annum is charged. The facility fee was $126 for the year ended
December 31, 1998 and $80 for the period from June 1997 to December 31, 1997.
Prior to June 1997, the Company had a $65,000 bank revolving credit facility.
Interest rates were based on either the London Interbank Offered Rate or the
prime rate. Commitment fees for the period January 1997 through May 1997 and for
the year ended December 31, 1996, were $45 and $133, respectively.

        The senior notes and the revolving credit facility contain certain
convenants, the most significant of which require a specified ratio of earnings
before interest and taxes to cover fixed charges, maintaining a minimum net
worth amount, and a specified debt to capitalization ratio. At December 31,
1998, the Company was in compliance with these covenants.

        The Company has access to a $10,000 short-term uncommitted facility for
foreign or trade related borrowings. The facility, which originated during 1998
and expires in August 1999, is renewable at the Companys request and the banks
option. The total outstanding at December 31, 1998, was $5,354. Interest rates
are based on either the London Interbank Offered Rate or the Tokyo Interbank
Offered Rate. The average interest rate for the short-term facility was 1.15% at
year-end 1998.

        The Company also has access to an uncommitted facility for the issuance
of foreign currency letters of credit. The total outstanding at December 31,
1998, was $1,642. The possibility of default is considered remote but would
cause these letters of credit to come due immediately. If this occurred,
payments would be made from available cash or borrowings under the revolving
credit facility.

        The net deferred tax liability at December 31, 1998 and 1997 consists of
a long-term deferred tax liability of $13,501 and $10,130, respectively, and a
current deferred tax asset of $3,138 and $2,824, respectively. The current
deferred tax asset is included in prepaid expenses and other current assets in
the consolidated balance sheets.

        In assessing the realizability of deferred tax assets, management
considers whether it is more likely than not that some portion or all of the
deferred tax assets will not be realized. The ultimate realization of deferred
tax assets is dependent upon the generation of future taxable income during the
periods in which those temporary differences become deductible. Management
considers the scheduled reversal of deferred tax liabilities, recoverable taxes
paid, projected taxable income and tax planning strategies in making this
assessment. Based on the reversal of existing deferred tax liabilities and
projections for future taxable income over the periods in which the deferred tax
assets are deductible, management believes it is more likely than not the
Company will realize the benefit of these deductible differences.

        Current income taxes payable of $3,569 at December 31, 1998, and
refundable income taxes of $2,655 at December 31, 1997, are included in accrued

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS CONTINUED

        As a result of the Merger described in note 1, the Company assumed
liability for the prior tax returns of First Mississippi. The federal income tax
returns have been examined through June 30, 1996, and all years prior to June
30, 1989 are closed. In December 1998, the Company agreed to a resolution of the
remaining disputed issues for the years ended June 30, 1989 through June 30,
1996. Management believes that adequate provision has been made for any
adjustments which might be assessed for open years through December 31, 1998.

8.      EMPLOYEE BENEFIT AND INCENTIVE PLANS

        The Company has a noncontributory defined benefit pension plan covering
substantially all full-time permanent employees. The benefits are based on years
of service and participants compensation during the last five years of
employment. The following tables present plan information at December 31, 1998
and 1997, and for the years ended December 31, 1998, 1997 and 1996: December 31,

        Net annual pension expense allocated to discontinued operations was
$1,211, $1,162 and $1,354 for the years ended December 31, 1998, 1997 and 1996,
respectively. Plan assets are invested primarily in equity securities and U. S.
Government and corporate bonds.

        The Company has a contributory 401(k) savings plan and an employee stock
ownership plan, both of which cover substantially all eligible employees who
have completed six months of service. Total expense under the plans amounted to
approximately $1,116, $1,038 and $813 for the years ended December 31, 1998,
1997 and 1996, respectively. These plans and the pension plan invest in the
Companys stock. The total number of shares held by the plans at December 31,
1998 and 1997, was 387,261 and 355,964, respectively.

        The Company has various nonqualified plans that act to restore earned
benefits limited by income tax regulations, or allow for other compensation
deferrals. Beginning in July 1997, participants in certain of these plans could
elect to convert existing deferred balances and/or future deferrals, at the
start of each new year, into phantom share units tracking the performance of the
Companys stock. Additionally, a 15 percent discount on the market value of the
stock at the original conversion date and each new plan year is given to those
participants making this election. Beginning in 1998, Company officers could
elect to defer a portion of salary and/or bonuses into phantom share units on a
pretax basis at a 15 percent discount. The total liability for these deferrals
at December 31, 1998 is $936. The nonqualified supplemental pension plan
provides for incremental pension payments from the Companys funds, and is based
on the same actuarial assumptions as the qualified plan. The total liability
relating to this unfunded plan at December 31, 1998 and 1997, was $1,689 and
$1,378, respectively. Net annual pension expense for this plan was $311, $77
(net of an actuarial adjustment of $233), and $250 for the years ended December
31, 1998, 1997 and 1996, respectively. The cost of the nonqualified 401(k) and
ESOP plans was $355, $622 and $274 for the years ended December 1998, 1997 and
1996, respectively. Individual life insurance contracts were purchased, with the
Company as beneficiary, to assist in the funding of portions of certain
nonqualified deferred compensation plans covering directors, officers and key
employees. The expense for these plans was $896, $795 and $802 for the years
ended December 31, 1998, 1997 and 1996, respectively.

        Directors, officers and certain key employees of the Company participate
in the long-term incentive plans (the Plans) under which the Company has
reserved shares of common stock for issuance. Awards under the Plans include
stock options, options to purchase debentures convertible into preferred stock
and then convertible into common stock of the Company, stock appreciation
rights, performance units, restricted stock, supplemental cash and such other
forms as the Board of Directors may direct. Options under all plans are granted
at the market price of the shares on the date of the grants, with vesting
occurring no earlier than six months after grant and expiration no later than 10
years after grant. At December 31, 1998, shares available for grant under the
referenced plans totaled 694,113 shares of common stock. Additional information

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS CONTINUED

        * The number of shares of common stock underlying outstanding
debentures, debenture options and nonqualifying stock options, as well as stock
option prices, were adjusted to reflect the distribution value of the fertilizer
business sale (note 2). This adjustment, which increased the number of shares
underlying the outstanding awards and reduced the exercise prices by a factor of
1.25 is reflected in the total number of shares and ending average option prices
at December 31, 1998, 1997 and 1996.

        In accordance with SFAS No. 123, the following additional disclosures
are required related to stock-based compensation shares granted during the
three-year period ended December 31, 1998:

        The fair value of each grant is estimated on the date of grant using the
Black-Scholes option-pricing model with the following weighted-average
assumptions used for grants made during the years ended December 31, 1998, 1997
and 1996, respectively: dividend yields of 1.5, 1.7 and 2.1 percent; expected
volatilities of 33, 26 and 25 percent; risk-free interest rates of 6.1, 6.8 and
6.9 percent, and expected lives of four years for all periods presented. A
summary of the status of the Companys stock-based compensation shares at
December 31, 1998, 1997 and 1996, and changes during the years ended on those
dates is presented below:

        The Company applies APB Opinion 25 and related interpretations in
accounting for its plans. Accordingly, no compensation cost has been recognized
for its stock-based compensation plans. Had compensation cost been determined
based on the fair value at the grant dates for awards under the plan consistent
with the method prescribed by SFAS No. 123, the Companys net income, earnings
per common share and earnings per common share, assuming dilution, would have
been reduced to the pro forma amounts indicated below for the years ended
December 31:

9.      STOCKHOLDERS' EQUITY

        Earnings per common share calculations are based on the weighted average
number of common shares outstanding during each year. Calculations for fully
diluted earnings per common share are based on the weighted average number of
outstanding common shares and common share equivalents during each year. A
reconciliation of the numerators and denominators for basic and diluted per
share computations from continuing operations for the years ended December 31,
1998, 1997 and 1996 follows:

        In connection with the Shareholder Rights Plan adopted by the Company on
October 30, 1996, preferred stock purchase rights were distributed to
stockholders and are deemed to be attached to the outstanding shares of common
stock of the Company. Under certain conditions, each right may be exercised to
purchase one one-hundredth (1/100) of a share of a new series of preferred
stock, at an exercise price of $100 per share (subject to adjustment). The
rights, which do not have voting rights, expire in 2006 and may be redeemed by
the Company at a price of $0.01 per right prior to a specified period of time
after the occurrence of certain events. In certain events, each right (except
certain rights beneficially owned by 10% or more owners, which rights are
voided) will entitle its holder to purchase shares of common stock with a value
of twice the then-current exercise price.

        In August 1998, the Companys directors authorized a $50,000 stock
repurchase program. This addition brings total repurchase authorizations, since
inception at January 1997, to $110,000.

        Provisions applicable to certain transportation equipment leases provide
for mileage credits computed on the basis of usage. No recognition has been
given to the effect of such credits in the amounts presented above.

        Rental expense, including short-term rentals (net of mileage credits and
short-term subleases of approximately $483, $407 and $244 for the years ended
December 31, 1998, 1997 and 1996, respectively), was approximately $1,590, $781
and $1,012 for the years ended December 31, 1998, 1997 and 1996, respectively.
In most cases management expects that leases will be renewed or replaced by
other leases in the normal course of business.

        Company operations are subject to a wide variety of environmental laws
and regulations governing emissions to the air, discharges to water sources, and
the handling, storage, treatment and disposal of waste materials, as well as
other laws and regulations concerning health and safety conditions. The Company
accrues for anticipated costs associated with investigatory and remediation
efforts relating to the environment. At December 31, 1998 and 1997, the Companys
estimated liability for these matters totaled $1,338 and $1,399, respectively,
for discontinued operations. The estimated liability related to continuing
operations at December 31, 1998 was $244.

        The Company has pending several claims incurred in the normal course of
business which, in the opinion of management and legal counsel, can be disposed
of without material effect on the accompanying consolidated financial
statements.

12.     SEGMENT INFORMATION

        The Company operates in two segments: Electronic and Other Specialty
Chemicals and Polyurethane Chemicals. The Electronic and Other Specialty
Chemicals segment produces specialty chemicals for use by others in electronic,
agricultural, pharmaceutical, polymer and photosensitive applications. These
chemicals are typically produced by multi-step batch processing with products
sold both on specification and performance. This segment includes research and
development for new products and processes. The Polyurethane Chemicals segment
produces aniline and nitrobenzene by a continuous production process. These
chemicals generally require more processing to produce the end product used by
consumers and are primarily sold under long-term contracts to industrial
customers. The accounting policies of the segments are the same as those
described in the summary of significant accounting policies. The Company
evaluates performance and allocates resources based on the segments profit or
loss from operations before interest income and expense and income taxes. The
Company's reportable segments are based on similarities in products and
services, type and class of customers, production processes and methods of
distribution.

        The polyurethane chemicals segment had unaffiliated major customer sales
of $99,522, $86,806 and $75,910 for the years ended December 31, 1998, 1997 and
1996, respectively.

        The following is a breakdown by segment of certain Company financial

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS CONTINUED

        Revenues from sales to all foreign countries were $46,207, $43,096 and
$36,982 in 1998, 1997 and 1996, respectively, and are attributed to those
countries based on ship-to location of customers. Identifiable assets in foreign
countries were $17,386, $7,736 and $5,881.

        Identifiable assets by segment are those assets used in the Companys
operations. Corporate assets and investments are principally cash and cash
equivalents, nontrade receivables and certain other investments.

        The Company performs ongoing credit evaluations of its customers and
generally does not require collateral on trade receivables. The Company believes
that adequate allowances are maintained for any uncollectible trade receivables.
Certain corporate expenses, primarily those related to the overall management of
the Company, were not allocated to the operating segments.

        Net earnings increased during the fourth quarter of 1997 due to the gain
on the sale of Melamine Chemicals, Inc. (note 3).

        The above quarterly earnings (loss) per share calculations are based on
the weighted average number of common shares outstanding during each quarter for
earnings (loss) per common share and the weighted average number of outstanding
common shares and common share equivalents during each quarter for the earnings
(loss) per common share, assuming dilution. The annual earnings (loss) per share
calculations are based on the weighted average number of common shares
outstanding during each year for earnings (loss) per common share and the
weighted average number of outstanding common shares and common share
equivalents during each year for earnings (loss) per common share, assuming
dilution.

15.     FINANCIAL INSTRUMENTS

        FAIR VALUE OF FINANCIAL INSTRUMENTS

        At December 31, 1998 and 1997, cash and cash equivalents, trade
receivables, notes receivable, trade payables, accrued liabilities and notes
payable are reflected in the financial statements at fair value. The $20,000
senior notes, placed with institutional investors in November 1998, approximate
fair value based on current rates offered the Company for debt of similar
characteristics and maturities. The revolving credit facilities have floating
interest rates and approximate fair value.

        DERIVATIVE FINANCIAL INSTRUMENTS

        The Company enters into forward foreign exchange contracts to minimize
its exposure related to foreign receivables denominated in yen. To lessen the
short-term effect of exchange rate fluctuations on consolidated performance, the
Company hedges a portion of these yen-denominated receivables and future sales
commitments. The forward contracts related to existing receivables are
marked-to-market each month and offset the underlying hedged transaction. Gains
and losses on contracts related to firm sales commitments are deferred and
recorded in net income in the period in which the related transactions are
consummated. The open contracts at December 31, 1998, represent forward sales of
664,500,000 yen with a U.S. dollar value of $5,857 and have terms of one year or
less.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS CONTINUED

16.     YEAR 2000 (UNAUDITED)

        In 1996, the Company began a study which led to the purchase in 1997 of
a company-wide Enterprise Resource Planning (ERP) system to integrate the
Companys information systems, replacing small, stand-alone purchased systems.
The ERP system will be Year 2000 compliant, with the material portion of the
system planned for completion by the middle of 1999. Installation is being
completed in stages, with the first sites converted at December 31, 1998. To
date, the Company has spent $8,900 on this project, and is projecting to spend
approximately $2,000 in 1999 on this project. If difficulties are encountered
that delay the ERP system implementation, contingency plans provide for the
purchase of select Year 2000 compliant personal computer software products, the
cost of which should not be material.

        A corporate-wide survey of other information technology (IT) and non-IT
equipment and systems utilizing date or time functions has been undertaken. The
current estimated cost to remediate is less than $600, most of which will be
incurred in 1999. Remediation, including verification testing, of most
noncompliant systems, equipment and software is targeted for completion by April
30, 1999. Some remediations at the Pascagoula facility, however, will occur in
the fourth quarter of 1999 to coincide with the next scheduled plant maintenance
turnaround. Contingency plans are currently being developed in the event the
remediations do not occur or are delayed. Severe delay or widespread failure
affecting both the remediation effort and the contingency plans, although not
expected, could have a material effect on the Companys financial condition and
results of operations.

        Key customers, as well as service and raw material suppliers, are being
surveyed about their Year 2000 readiness. Depending on their responses,
contingency plans will be developed as appropriate. It is anticipated that this
process will be completed no later than September 30, 1999. Although the Company
cannot quantify the precise effect, significant or prolonged disruptions of key
customers or suppliers could have a material effect on the Companys financial
condition and results of operations. For example, the majority of aniline
produced by the Company is sold through long-term contracts to a few customers.
Their inability to utilize the Companys aniline could have a material adverse
effect.


INDEPENDENT AUDITORS REPORT

The Board of Directors and Stockholders
ChemFirst Inc.

        We have audited the consolidated balance sheets of ChemFirst Inc. and
subsidiaries as of December 31, 1998 and 1997, and the related consolidated
statements of operations, stockholders equity and cash flows for each of the
years in the three-year period ended December 31, 1998. These consolidated
financial statements are the responsibility of the Companys management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.

        We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

        In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of ChemFirst
Inc. and subsidiaries as of December 31, 1998 and 1997, and the results of their
operations and their cash flows for each of the years in the three-year period
ended December 31, 1998, in conformity with generally accepted accounting
principles.
