                                THE TRANSACTIONS
 
In the fourth quarter of 1998, Minorco announced that it was merging with Anglo
American Corporation of South Africa Limited and that it would sell all the
shares of common stock of Engelhard owned by Minorco and its affiliates,
approximately 46 million shares.
 
On March 2, 1999, we announced that Minorco would sell 26 million shares in this
offering and we also agreed to purchase approximately 18 million of our shares
owned by Minorco. We will purchase those shares for $18.72 per share. The 18
million shares represent approximately 13% of our total shares outstanding.
Minorco has agreed to compensate us for our costs and other expenses relating to
this offering and our purchase of the shares.
 
We plan to initially finance the purchase with short-term debt and intend to
take steps to reduce our total debt going forward. We do not believe the
financing of the purchase will have any material impact on our liquidity. We
anticipate issuing $100 million of bonds by mid-1999 to retire a portion of the
short-term debt, which is not expected to have a material impact on our total
interest expense. We are reviewing our portfolio to identify non-core assets and
businesses for potential sale and exploring ways to further reduce operating
expenses. We expect the buy-back to increase our earnings per share. If we had
purchased the 18 million shares from Minorco on January 1, 1998 at a price of
$18.72 per share, we estimate that our 1998 earnings per share would have
increased by approximately $.10 per share on a basic basis and $.09 per share on
a diluted basis.
 
The following table lists the shares Minorco is selling:

                              RECENT DEVELOPMENTS
 
On April 22, 1999, we reported that net earnings for the first quarter ended
March 31 declined 6% to $40.5 million, compared with 1998 first-quarter net
earnings of $43.2 million. Earnings per share on a diluted basis for the quarter
declined to 28 cents from 30 cents a year ago.
 
First-quarter sales reached $1,073 million, up 11% from $971 million in last
year's first quarter.
 
As we previously announced, the first-quarter shortfall reflects the comparison
with unusually high earnings from our industrial commodities management business
in the year-ago quarter.

                      SUMMARY CONSOLIDATED FINANCIAL DATA
 
The following table sets forth consolidated financial data for Engelhard for
each of the fiscal years in the five year period ended December 31, 1998 and as
of December 31, 1998 which has been derived from our audited consolidated
financial statements for such years, which have been audited by
PricewaterhouseCoopers LLP, independent accountants. You should read this
information in conjunction with "Capitalization," "Selected Consolidated
Financial Data," "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and our consolidated financial statements and
accompanying notes included in this prospectus.
 
The basic earnings per share calculation is computed by dividing net earnings by
the average number of shares outstanding. The diluted earnings per share
calculation includes the average number of shares outstanding plus the effect of
dilutive stock options. In addition, diluted earnings per share in 1998 includes
shares held in Engelhard's Rabbi Trust described in Note 13 to our Consolidated
Financial Statements. All per share amounts reflect the three-for-two stock
split as of June 30, 1995.
 
"EBITDA" consists of operating earnings plus depreciation and amortization.
EBITDA is a commonly used measure of financial performance and is presented to
enhance the understanding of Engelhard's operating results. EBITDA is not a
measure of financial performance under GAAP and may not be comparable to other
similarly titled measures of other companies. EBITDA should not be considered as
an alternative to operating or net income as an indicator of Engelhard's
performance or as an alternative to cash flows from operating activities as a
measure of liquidity. See Engelhard's Consolidated Statements of Earnings and
Consolidated Statements of Cash Flows and notes thereto, included elsewhere in
this prospectus.

                                  RISK FACTORS
 
In addition to the other information in this prospectus, you should carefully
consider the following factors before making an investment decision in the
shares of our common stock offered by this prospectus.
 
OUR SENIOR UNSECURED DEBT RATING WILL BE DOWNGRADED AS A RESULT OF THE MINORCO
STOCK PURCHASE
 
Standard & Poor's has indicated that, upon completion of the Minorco stock
purchase, it will lower our senior unsecured debt rating to A- and our
commercial paper rating from A-1 to A-2. Moody's has confirmed our senior
unsecured debt rating at A3 and our commercial paper rating at P-2. We expect
that the Standard & Poor's downgrade will result in an increase in our borrowing
rates but we do not expect it to be significant.
 
WE HAVE A SIGNIFICANT AMOUNT OF INDEBTEDNESS
 
We have a significant level of indebtedness, which could have important
consequences to you. For example, it:
 
- - will require us to dedicate a material portion of our cash flow from
  operations to make payments on our indebtedness, thereby reducing the
  availability of our cash flow to fund working capital, capital expenditures,
  acquisitions or other general corporate purposes.
 
- - could make us less attractive to prospective or existing customers or less
  attractive to potential acquisition targets.
 
- - may limit our flexibility to adjust to changing business and market conditions
  and make us more vulnerable to a downturn in general economic conditions as
  compared to a competitor that may be less leveraged.
 
After giving effect to borrowings we will make to finance the purchase of shares
from Minorco, we estimate that we will have in excess of $1 billion of total
debt as compared to $604.6 million of total shareholders' equity at December 31,
1998. We estimate that approximately $552 million of our debt will be in the
form of short-term bank borrowings and commercial paper. Significant increases
in short-term interest rates would significantly increase our interest expense.
 
SOME OF OUR COMPETITORS MAY HAVE GREATER FINANCIAL, TECHNICAL, MARKETING AND
OTHER RESOURCES THAN US
 
The industries in which we compete are highly competitive and most of our
customers use more than one supplier. Some of our competitors may have greater
financial, technical, marketing and other resources, which could provide them
with a competitive advantage over us. Significant competitors in some of our
business segments include other large, well-established companies such as W.R.
Grace, Akzo, Johnson Matthey and DeGussa.
 
Our competitors can be expected to continue to develop and introduce new and
enhanced products, which could cause a decline in market acceptance of our
products. In addition, our competitors could cause a reduction in the prices for
some of our products as a result of intensified price competition.
 
FAILURE TO MAKE CONTINUED IMPROVEMENTS IN OUR TECHNOLOGY AND PRODUCTIVITY COULD
HURT OUR COMPETITIVE POSITION
 
Many of our products could be affected by rapid technological change and new
product introductions and enhancements. We believe we must continue to enhance
our existing products and to develop and manufacture new products with improved
capabilities in order to
 
                                       10
<PAGE>   11
 
continue to be a market leader. We also believe that we must continue to make
improvements in our productivity in order to maintain our competitive position.
Our inability to anticipate, respond to or utilize changing technologies could
have a material adverse effect on our business and results of operations.
 
MANY OF OUR CUSTOMERS ARE IN CYCLICAL INDUSTRIES
 
A majority of our profits are derived from customers which are in industries and
businesses that are cyclical in nature and sensitive to changes in general
economic conditions, such as the chemical and automotive industries. The demand
for our products depends upon the general economic conditions of the markets of
our customers. Downward economic cycles in our customers' industries may reduce
sales of our products.
 
CURRENCY FLUCTUATIONS COULD IMPACT OUR FINANCIAL PERFORMANCE
 
Our products are sold around the world and, as a result, currency fluctuations
could impact our financial performance in the future. Our revenues in foreign
countries largely are generated in foreign currencies, while costs incurred to
generate those revenues are only partly incurred in the same currencies. Since
our financial statements are denominated in U.S. dollars, changes in currency
exchange rates between the U.S. dollar and other currencies can have an impact
on our earnings. To reduce this currency exchange risk, we enter into foreign
currency forward contracts to hedge our exposure in certain currencies to reduce
the risk of an adverse currency exchange movement but such hedging positions do
not eliminate the risks associated with currency fluctuations.
 
WE ARE VULNERABLE TO GLOBAL AND REGIONAL ECONOMIC CONDITIONS
 
Engelhard's international operations are subject to a number of other potential
risks. Such risks include, among others, currency exchange controls, labor
unrest, regional economic uncertainty, political instability, restrictions on
the transfer of funds into or out of a country, export duties and quotas,
domestic and foreign customs and tariffs, current and changing regulatory
environments, difficulty in obtaining distribution support and potentially
adverse tax consequences. These factors could have an adverse effect on our
international operations in the future by reducing the demand for our products,
increasing the prices at which we can sell our products and otherwise having an
adverse affect on our results of operations. In recent years Asian economies
have been highly volatile and recessionary, resulting in significant
fluctuations in local currencies and other instabilities. These instabilities
may continue or worsen, which could have a continued adverse impact on our
results of operations.
 
FUTURE GROWTH OF OUR ENVIRONMENTAL TECHNOLOGIES SEGMENT DEPENDS IN PART
ON TIGHTENING OF EMISSIONS STANDARDS WORLDWIDE
 
We expect that our future business growth in our Environmental Technologies
segment will be driven, in part, by tightening of emissions standards worldwide.
If such standards do not continue to become stricter or are loosened by
governmental authorities, it could have an adverse impact on the results of
operations of this segment.
 
CHANGES IN ENVIRONMENTAL LAWS AND REGULATIONS COULD SUBJECT US TO SIGNIFICANT
FUTURE LIABILITIES
 
In the ordinary course of our business, like most other industrial companies, we
are subject to numerous environmental laws and regulations which impose various
environmental controls on, among other things, the discharge of pollutants into
the air and water and the handling, use, storage, disposal and clean-up of solid
and hazardous wastes. These laws and regulations govern actions that may have
adverse environmental effects and also require compliance with certain practices
when handling and disposing of hazardous and non-hazardous wastes. These
 
                                       11
<PAGE>   12
 
laws and regulations also impose liability for the costs of, and damages
resulting from, cleaning up sites, past spills, disposals and other releases of
hazardous substances. Changes in these laws and regulations may have a material
adverse effect on our financial position and results of operations. Any failure
by us to adequately comply with such laws and regulations could subject us to
significant future liabilities.
 
IF YEAR 2000 PROBLEMS ARE SIGNIFICANT, WE COULD HAVE INTERRUPTIONS IN, OR
FAILURES OF, OUR NORMAL BUSINESS OPERATIONS
 
The ability of computers, software or any equipment utilizing microprocessors to
properly recognize and process data at the turn of century is commonly referred
to as a Y2K compliance issue. The failure to correct a material Y2K compliance
problem could result in an interruption in, or a failure of, certain normal
business activities or operations. Such failures could have a material adverse
impact on the operations of Engelhard and its customers.
 
We have already taken substantial steps to address the Y2K issue. We believe
that, with the implementation of new business systems and completion of our Y2K
project as scheduled, the possibility of significant interruptions of our normal
operations is reduced. However, we cannot assure you that we will identify and
address all significant internal or external Y2K problems in a prompt and
cost-effective manner. Such Y2K problems, if not fixed, could have a material
adverse effect on our business, results of operations or financial condition.
For a more complete discussion of Y2K issues, you should read "Management's
Discussion and Analysis of Financial Condition and Results of Operations -- Year
2000 Update."
 
FLUCTUATIONS IN THE SUPPLY AND PRICES OF PRECIOUS AND BASE METALS
COULD NEGATIVELY IMPACT OUR FINANCIAL RESULTS
 
Our Environmental Technologies and Process Technologies segments are dependent
on the availability of precious platinum group metals to manufacture many of
their products. Accordingly, the availability of platinum group metals and
fluctuations in the supply and prices of precious and base metals could impair
our ability to procure the necessary materials to, or increase our costs to,
manufacture our products. Our Industrial Commodities Management segment is
responsible for procuring precious and base metals to meet the requirements of
our operations and our customers. Supplies of newly mined platinum group metals
are obtained primarily from South Africa and the Russian Federation and, to a
lesser extent, the United States and Canada, the only four regions that are
known significant sources. In addition, in limited and closely monitored
situations for which exposure levels have been set by senior management, our
Industrial Commodities Management business holds significant unhedged metal
positions that can be subject to future market fluctuations that could result in
a negative impact on our financial results.

                      SELECTED CONSOLIDATED FINANCIAL DATA
 
The following table sets forth consolidated financial data for Engelhard for,
and as of, each of the fiscal years in the five year period ended December 31,
1998 that has been derived from our audited consolidated financial statements
for such years, which have been audited by PricewaterhouseCoopers LLP,
independent accountants. You should read this information in conjunction with
"Capitalization," "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and our consolidated financial statements and
accompanying notes included in this prospectus.
 
The basic earnings per share calculation is computed by dividing net earnings by
the average number of shares outstanding. The diluted earnings per share
calculation includes the average number of shares outstanding plus the effect of
dilutive stock options. In addition, diluted earnings per share in 1998 includes
shares held in Engelhard's Rabbi Trust described in Note 13 to our Consolidated
Financial Statements. All per share amounts reflect the three-for-two stock
split as of June 30, 1995.
 
"EBITDA" consists of operating earnings plus depreciation and amortization.
EBITDA is a commonly used measure of financial performance and is presented to
enhance the understanding of Engelhard's operating results. EBITDA is not a
measure of financial performance under GAAP and may not be comparable to other
similarly titled measures of other companies. EBITDA should not be considered as
an alternative to operating or net income as an indicator of Engelhard's
performance or as an alternative to cash flows from operating activities as a
measure of liquidity. See Engelhard's Consolidated Statements of Earnings and
Consolidated Statements of Cash Flows and notes thereto, included elsewhere in
this prospectus.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
 
Unless otherwise indicated, all per-share amounts are presented as basic
earnings per share, as calculated under SFAS No. 128, "Earnings per Share."
 
RESULTS OF OPERATIONS
 
Net earnings in 1997 include special and other charges of $117.7 million ($0.82
per share) for a variety of events, including restructuring actions and a loss
from the base-metal fraud in Japan (see "Business--Legal Proceedings and
Contingencies" for detail).
 
The information in the discussion of each segment's results is derived directly
from that segment's internal financial reporting system used for Management
purposes. Items allocated to the segment's results include various corporate
overhead charges such as expenses for information technology, research and
development, and site management. Unallocated items include interest expense,
royalty income, sale of inventory accounted for under the LIFO method, special
and other charges and other miscellaneous Corporate items (see Note 15 of the
Notes to Consolidated Financial Statements for further detail on Engelhard's
segment reporting).
 
ENVIRONMENTAL TECHNOLOGIES
 
The Environmental Technologies segment develops and markets sophisticated
technologies and systems to control emissions from mobile and stationary
sources. These technologies enable customers to cost-effectively meet stringent
environmental regulations.
 
1998 Performance
 
Sales increased 9% to $558.5 million, and operating earnings increased 22% to
$83.5 million.
 
Discussion
 
The segment's operating earnings grew at a greater rate than sales as a result
of three key factors:
1) sale of higher-value, more sophisticated emission-control technologies
   required to meet stricter environmental regulations;
2) lower manufacturing and overall operating costs; and
3) the absence of losses from the portion of the stationary-source,
   emission-control business related to capital equipment, which was sold in
   February 1998.
 
More than 80% of the segment's sales and more than 90% of its operating earnings
came from technologies to control emissions from mobile sources, including
gasoline- and diesel-powered passenger cars, sport utility vehicles, trucks,
buses and off-road vehicles. Sales and operating earnings from these
technologies increased 12% and 13%, respectively. Continuing demand for the more
sophisticated emission-control technologies drove sales increases in both Europe
and North America. In Europe, the volume increase resulted from greater share
with major European automakers. In North America, a major volume gain resulted
from increased shipments to General Motors for their redesigned full-size
trucks.
 
Outlook
 
We expect demand for environmental technologies to increase, driven by
tightening air-emission standards worldwide. In 1998, for example, the
California Air Resources Board (CARB)--a leader for the world's clean-air
initiatives--enacted more stringent regulations for passenger cars, light
trucks, minivans and sport utility vehicles for the 2004 model year. Compliance
with stricter standards will likely require more sophisticated catalyst systems,
which plays to Engelhard's technology strength. Additionally, the U.S.
Environmental Protection Agency has
 
                                       19
<PAGE>   20
 
accelerated the effective date for stricter diesel truck regulations to 2002
from 2004, driving development of new catalyst systems for diesel engine
manufacturers. Beginning in 1999, we expect new sales of our diesel retrofit
systems for several major urban bus programs.
 
We are bolstering manufacturing capacity in emerging markets where the phase-out
of leaded fuels is driving catalyst demand. Engelhard Environmental Systems,
Ltd., a joint venture of Engelhard and UCAL Fuel Systems Ltd., opened India's
first emission-catalyst plant in June 1998. We also broke ground for a plant in
Brazil, which will supply a major automaker's South American operations
beginning in mid-1999.
 
Some automakers continue to emphasize the environmental benefits of their
vehicles. For example, Volvo announced that it will include Engelhard's
proprietary PremAir(R) catalyst system on the Volvo S80 luxury sedan beginning
in late 1999. When applied to an automobile's radiator, PremAir converts
ground-level ozone into oxygen.
 
ENVIRONMENTAL TECHNOLOGIES--PRIOR-YEAR COMPARISONS
 
1997 compared with 1996
 
Sales increased 10% to $512.4 million, and operating earnings increased 27% to
$68.3 million.
 
Sales from mobile-source, emission-control technologies grew 16%, while
operating earnings increased 43%. Earnings growth outpaced the sales increase
due to the sale of higher-value, more sophisticated emission-control
technologies required to meet stricter environmental regulations, improved
utilization of existing manufacturing capacity and other productivity
improvements. New volume from several European automakers provided the majority
of the sales growth.
 
1996 compared with 1995
 
Sales increased 31% to $465.7 million, and operating earnings increased 63% to
$53.9 million.
 
Sales from mobile-source, emission-control technologies grew 24%, while
operating earnings grew 73%. The increases were driven by demand for the more
sophisticated new technologies needed to meet stricter environmental
regulations. Share growth at Ford Motor Company in North America and new
customers in Europe provided the majority of the sales increase.
 
PROCESS TECHNOLOGIES
 
The Process Technologies segment helps customers make their processes more
productive, efficient, environmentally sound and safer. The segment supplies
advanced chemical and polymerization catalysts, sorbents and separation
products. In addition, the segment's advanced cracking and hydroprocessing
technologies enable petroleum refiners to more efficiently produce gasoline,
transportation fuels and heating oils.
 
1998 Performance
 
Sales increased 19% to $533.3 million, and operating earnings increased 41% to
$78.5 million.
 
Discussion
 
Sales and earnings growth were driven by the May 1998 acquisition of the
catalyst businesses of Mallinckrodt Inc., which accounted for $67.7 million in
sales and $16.2 million in operating earnings in 1998. The operating earnings
increase also reflects a lower overall cost structure for the petroleum
catalysts business. The lower cost structure resulted from the mid-1998 shutdown
of a manufacturing facility in The Netherlands, manufacturing efficiencies and
reduced administrative expenses. The plant shutdown reduced fixed costs by $4.0
million in 1998. The manufacturing efficiencies accounted for $6.0 million,
while the reduced administra-
 
                                       20
<PAGE>   21
 
tive expenses totaled $3.0 million. Global customer needs for fluid catalytic
cracking (FCC) catalysts are now being met from expanded facilities in North
America.
 
   
The acquisition broadened and strengthened the segment's existing product
offering and gave it a position in the high-growth polymerization catalyst
market segment. This business is now a major producer of custom and licensed
catalysts for the manufacture of polypropylene, one of the fastest growing
segments of the polyolefin market. The polypropylene market segment is expected
to grow about 6% per year compared with growth rates of about 3%-5% for other
polymerization catalyst market segments. This portion of the business had enough
new commitments to justify significant expansions shortly following the
acquisition. These expansions will increase capacity by about 20%.
    
 
Excluding the results of the acquisition, operating earnings for the segment
would have increased 12%, largely due to the improved performance from petroleum
catalysts, which more than offset declines from petrochemical catalysts. Overall
competitive weakness in the chemical industry reduced demand for petrochemical
catalysts.
 
Outlook
 
We expect earnings growth opportunities for chemical catalysts to be driven by:
 
1) a favorable comparison from the full-year inclusion of results from the
   acquired Mallinckrodt businesses; and
 
2) anticipated strong demand for polypropylene catalysts.
 
We expect new capacity to be on stream by mid-year, and, based on continuing
indications of growing demand, we are planning to add even more capacity in the
second half of the year. We anticipate weakness in the chemical industry to
continue to negatively affect demand for petrochemical catalysts. As a result,
the business intends to focus on aggressively controlling operating costs.
 
Lower spreads between light and heavy crude oils flattened demand for FCC
catalysts in recent years. Petroleum refiners use FCC catalysts to break down
crude oil in gasoline and other transportation and heating fuels. Refining
lighter crudes requires a reduced quantity of catalysts as well as less
sophisticated catalyst technology. As a result, competing technologies have
become less differentiated. We expect demand for FCC catalysts to be relatively
flat for several years. To generate value, this business expects to aggressively
manage costs, maintain positive price momentum, capitalize on opportunities
inherent in process technology proprietary to Engelhard and pursue select growth
opportunites worldwide.
 
PROCESS TECHNOLOGIES--PRIOR-YEAR COMPARISONS
 
1997 compared with 1996
 
Sales increased 3% to $447.5 million, and operating earnings decreased 5% to
$55.6 million.
 
Operating earnings from increased sales of chemical catalysts were offset by a
$6 million decline in operating earnings from petroleum catalysts, primarily the
result of continuing losses from European FCC catalyst operations. Sales of
petroleum catalysts were flat. The segment's sales gain reflects higher sales of
chemical catalysts driven by new alliances and the trend toward
decaptivation -- producing catalysts for customers who formerly made their own.
Alliances and decaptivation accounted for more than two thirds of the sales
increase.
 
1996 compared with 1995
 
Sales increased 7% to $433.3 million, and operating earnings increased 14% to
$58.6 million.
 
Strong economic conditions in the chemical industry and success in new business
programs led to sales and operating earnings increases. Volumes were up for all
product lines, most notably
 
                                       21
<PAGE>   22
 
for catalysts used to make PTA (the main component for polyester), catalysts
used to make PVC intermediates, and products to remove lead from drinking water.
Collectively, these product lines accounted for about 25% of the segment's sales
increase. Volume increases in petroleum catalysts were offset by lower pricing
due to excess capacity in the FCC catalyst industry.
 
PAPER PIGMENTS AND ADDITIVES
 
The Paper Pigments and Additives segment provides primarily kaolin-based
performance products used as coating and extender pigments by papermakers to
improve the opacity, brightness, gloss and printability of their products.
 
1998 Performance
 
Sales decreased 1% to $239.4 million, and operating earnings increased 6% to
$35.8 million.
 
Discussion
 
Operating earnings were up despite relatively flat sales as a result of ongoing
productivity initiatives, which accounted for substantially all of the increase.
The flat sales reflected an overall slowdown in the paper industry and reduced
demand resulting from some paper makers switching to a process that does not
require Kaolin-based pigments. Regionally, sales varied, with North American
sales down 10% from the prior year and Europe up 7%. Asia-Pacific volume grew
modestly, but prices there declined about 4%. The business launched Digitex(TM)
paper pigment, which enables large-scale commercial ink jet printers to
economically produce large, colorful graphics like those on billboards and bus
advertisements. The market's initial reception was positive, although shipments
primarily were for trial and testing purposes.
 
Outlook
 
We expect paper industry conditions to remain depressed. We believe recovery in
1999 will be gradual if it occurs at all. Unused industry capacity could again
impact pricing. In the face of these market conditions, the segment intends to
focus on aggressive cost reductions, sale of higher-value-add products and
continued introduction of new products. The segment is targeting increased sales
of newly introduced Digitex(TM) pigments as well as engineered pigments.
 
PAPER PIGMENTS AND ADDITIVES--PRIOR-YEAR COMPARISONS
 
1997 compared with 1996
 
Sales increased 2% to $242.0 million, and operating earnings decreased 19% to
$33.9 million.
 
Lower pricing was the primary factor in the operating earnings decline despite a
slight sales increase. The industry sought to address overcapacity issues by
lowering prices to boost manufacturing volume. Earnings also were adversely
affected by sales of lower margin products to certain customers in Asia and
unscheduled maintenance costs.
 
1996 compared with 1995
 
Sales decreased 1% to $237.6 million, and operating earnings decreased 13% to
$41.9 million.
 
Lower operating earnings resulted from reduced demand, which resulted from
depressed economic conditions in the paper industry. However, new performance
products developed and marketed during 1996 improved Engelhard's results
compared with much of the industry. Among these new products was Luminex(R), a
pigment bright enough to compete with more costly products and several other
pigments that work better on high-speed papermaking machines. These pigments are
based on a new, patented manufacturing process.

SPECIALTY PIGMENTS AND ADDITIVES
 
The Specialty Pigments and Additives segment provides functional additives to
customers in a broad array of markets, including coatings, plastics, cosmetics
and construction. The segment also provides iridescent films used in a variety
of creative, decorative and packaging applications. The segment's products help
customers improve the look, performance and overall cost of their products.
 
1998 Performance
 
Sales of $349.0 million were flat, and operating earnings decreased 35% to $42.0
million.
 
Discussion
 
Sales were flat as the impact of the economic downturn in the Asia-Pacific
region and lower selling prices offset increases in sales of pearlescent
pigments and attapulgite-based products. The economic crisis in Asia-Pacific
began in 1997 and continued throughout 1998. Sales in Asia of pearlescent
pigments and specialty-mineral products decreased 24% to $33.1 million.
Competitive pressures in our color and pearlescent pigment businesses drove
prices down about 1.5%. We expect prices to continue at the same level through
1999. Overall, sales of pearlescent pigments rose 1% to $139.1 million, on the
strength of increased demand from the cosmetics and industrial market segments.
Sales of attapulgite-based products increased 15% to $32.2 million, reflecting
the full-year inclusion of results from the acquisition of certain assets of
Floridin, which occurred in June 1997.
 
A number of factors resulted in reduced operating earnings. First, reduced sales
in Asia lowered earnings by $6.8 million, primarily in the industrial and
automotive segments served by the specialty pigments and specialty minerals
businesses. Second, operating earnings were reduced by another $4.9 million as a
result of a sales shift to less sophisticated color products, which was driven
by customer consolidations and vertical integration of a portion of the customer
base, particularly in the ink market segment. Third, operating earnings were
affected by price decreases of about 5%, which resulted from competitive
pressure in the specialty pigments business. Fourth, operating earnings were
adversely affected by $7.5 million as a result of an inventory-reduction program
completed in 1998. All other sales volume increases resulted in an earnings
increase of $1.0 million, due mostly to increased pearlescent pigment sales
outside the Asia-Pacific region. In addition, operating earnings from
attapulgite-based products were up $2.9 million, reflecting full-year benefit of
the Floridin acquisition.
 
Benefits of cost reduction and productivity initiatives resulted in savings of
$8.0 million in manufacturing costs, which partially was offset by operating
cost increases of $6.0 million and non-recurring items totaling $2.0 million.
 
Outlook
 
The segment intends to focus on aggressive cost management and implementation of
productivity improvements. We expect any improvement in economic conditions in
Asia will be slow. The segment has planned new product introductions to the
cosmetics and personal care markets as well as new product launches in the
specialty-mineral and optical-effect film businesses. The segment is targeting
increased sales of new glass-flake effect pigments across multiple market
segments, including: custom car finishes; motorcycles, gel coats for
automobiles, boats and personal watercraft; and plastic items such as toys and
skis.
 
SPECIALTY PIGMENTS AND ADDITIVES--PRIOR-YEAR COMPARISONS
 
1997 compared with 1996
 
Sales increased 34% to $349.0 million, and operating earnings rose 64% to $64.3
million.
 
                                       23

Sales and operating earnings growth were driven by the successful integration of
Mearl Corporation, which was acquired in May 1996. Full-year, pretax benefit of
the acquisition totaled $29.1 million. Capitalizing on cost, technology and
market-channel synergies, Engelhard continued to build its leadership in
pearlescent and color pigments, particularly in the automotive and cosmetics
industries. In 1997, Engelhard introduced a unique product line called
Cellini(R) which combines pearlescent and organic pigments. These unique
products better position Engelhard to capitalize on the growing, high-fashion
trend toward bright, vibrant color.
 
1996 compared with 1995
 
Sales increased 59% to $260.5 million, and operating earnings increased 64% to
$39.1 million.
 
Sales growth was driven by performance additives and color pigments and addition
of pearlescent pigment sales resulting from the acquisition of Mearl in May
1996. These factors contributed $15.2 million in operating earnings.
 
INDUSTRIAL COMMODITIES MANAGEMENT
 
The Industrial Commodities Management segment purchases and sells precious
metals, base metals and related products. It does so under a variety of pricing
and delivery arrangements structured to meet the logistical, financial and price
risk management requirements of Engelhard, its customers and suppliers.
Additionally, it offers related services for precious-metals refining and
produces salts and solutions.
 
1998 Performance
 
Sales increased 20% to $2,346.8 million and operating earnings increased 8% to
$48.4 million.
 
Discussion
 
Sales for this segment include all sales of metals to industrial customers plus
purchases for refining, which are resold to the market at the conclusion of the
refining process. The significant increase resulted primarily from higher
palladium and rhodium volumes and prices. Changes in metal sales amounts are not
necessarily indicative of changes in earnings because of the mix of potential
arrangements with customers and other factors that may affect dealing and
refining revenues. Operating earnings in 1998 were affected by lower margins
earned on metal sales. As described in Note 1 to our Consolidated Financial
Statements, the lower margins on Industrial Commodities Management sales are
driven by including precious metals in both sales and cost of sales for certain
transactions. Sales growth outpaced operating earnings as the result of higher
prices for certain platinum group metals.
 
Both 1998 and 1997 operating earnings benefited greatly from volatility in
platinum group metals. This volatility resulted primarily from the variability
of shipments from Russia, which impacted both spot prices and the relationship
of the spot price to forward prices. The situation was exacerbated by the
continually increasing demand for platinum, palladium and rhodium in the
manufacture of various products, including jewelry and automotive catalysts.
Volatility not only increases the spreads on dealing transactions, but also
provides opportunities to benefit from strong and prudent physical positions.
The increase in 1998 was partially offset by a decrease in pretax earnings from
Japanese base-metal dealing.
 
It should be noted that customers often supply the precious metals for
manufactured products. In those cases, precious-metal values are not included as
sales. The mix of such arrangements and the extent of market-price fluctuation
can significantly affect the level of reported sales, but do not usually have a
material effect on earnings. Precious metals are considered as sales if the
metal was supplied by Engelhard. Purchase of metal generally is hedged (see Note
1 to our Consolidated Financial Statements.)

<PAGE>   25
 
Outlook
 
While a sustainable level of base business is anticipated, market volatility,
such as described above, cannot be assured. The benefits of such volatility
represent an upside opportunity for this segment above its sustainable base
business.
 
INDUSTRIAL COMMODITIES MANAGEMENT--PRIOR-YEAR COMPARISONS
 
1997 compared with 1996
 
Sales increased 18% to $1,954.0 million and operating earnings increased 111% to
$44.9 million.
 
Strong increases in both sales and operating earnings were driven by unusually
high volatility in the platinum-group-metals markets. Refining operations,
although down slightly, also benefited from increased activity generated by the
market volatility.
 
1996 compared with 1995
 
Sales increased 39% to $1,659.1 million and operating earnings increased 8% to
$21.3 million.
 
Improvement was driven by strong performance in the precious-metals refining and
salts and solutions product lines.
 
SPECIAL AND OTHER CHARGES
 
In response to weak results of certain operations, and as a result of the
base-metal fraud in Japan, Engelhard recorded, in the fourth quarter of 1997,
special and other charges of $149.6 million ($117.7 million after tax). The
following table sets forth the impact of the special and other charges in the
1997 Consolidated Statement of Earnings:

The 1997 special and other charges are described below:
 
     - The Process Technologies segment incurred charges of $35.4 million
       primarily related to the closure and subsequent sale of a petroleum
       catalysts facility in The Netherlands used for the manufacture of fluid
       catalytic cracking (FCC) catalysts. Management approved a plan to improve
       the profitability of this business, primarily by lowering its cost
       structure and optimizing its manufacturing resources. The most
       significant action resulted in the 1998 sale of the FCC catalysts
       facility in The Netherlands. There was no gain or loss on the sale of the
       facility as the sales price approximated the carrying value as adjusted
       by
 
                                       25
<PAGE>   26
 
the special and other charges. This decision was driven by industry overcapacity
and the determination that Engelhard's European customers could be served more
efficiently by North American FCC catalysts operations. As a result, Engelhard
      provided for employee severance obligations of $6.4 million covering 90
      site employees, plant closure and other miscellaneous costs of $1.7
      million and asset write-downs of $27.3 million consisting of $22.1 million
      to reduce the carrying value of the facility to an estimate of fair value
      based on appraisals performed by third parties, a $2.7 million reserve for
      obsolete inventory, and $2.5 million to write-off intangible assets
      related to production technology which could no longer be utilized. These
      actions are expected to be substantially complete by the end of 1999.
 
       Management anticipated annual pretax savings of $11 million, consisting
of:
 
       Cash savings of $7 million due to the elimination of Terneuzen-based
       operating staff and non-Terneuzen-based-support staff involved in
       research and development and sales and marketing.
 
       Non-cash savings of $4 million due to the elimination of depreciation
       charges related to fixed assets written off.
 
       The actual pretax savings realized during 1998 were $7 million - $5
       million in cash savings and $2 million in non-cash savings. During 1999,
       management expects to realize the full pretax savings of $11 million.
 
   
     - The Environmental Technologies segment incurred charges of $29.6 million
       related to the sale of the stationary-source, emission-control capital
       equipment business. Management approved a plan to sell this business
       based on unfavorable market growth projections, combined with low
       technological barriers to enter this market. Management believes that
       this strategy will allow Engelhard to concentrate on its core
       competency--catalyst technology. Revenue and operating loss for the
       capital equipment business were $21.6 million and $6.4 million,
       respectively, for the year ended December 31, 1997 and $40.3 million and
       zero, respectively, for the year ended December 31, 1996. Engelhard
       continues to sell catalysts for stationary-source pollution abatement.
       Engelhard provided for losses on contracts and warranty costs of $7.9
       million and reduced the carrying value of goodwill and other assets by
       $21.7 million to an estimate of fair value based on negotiations with
       third parties. This write-down consisted of the write-off of goodwill of
       $15.0 million, a reserve for uncollectable accounts receivable of $4.2
       million and a reserve for obsolete inventory of $2.5 million. The sale
       was completed in February 1998 and there was no gain or loss on the sale
       of the business as the sales price approximated the carrying value as
       adjusted by the special and other charges. These actions are expected to
       be substantially complete by the end of 1999.
    
 
       Management anticipated annual pretax savings of $6 million, consisting
of:
 
       Cash savings of $5 million due to the elimination of losses generated by
       the capital equipment business.
 
       Non-cash savings of $1 million due to the elimination of amortization
       charges related to goodwill written off.
 
       The actual pretax savings realized during 1998 were $6 million - $5
       million in cash savings and $1 million in non-cash savings.
 
     - The Specialty Pigments and Additives segment wrote off assets of
       approximately $0.8 million.
 
     - Japan base-metal fraud of $39.0 million which is discussed in Note 18 to
       our Consolidated Financial Statements.
 
                                       26
<PAGE>   27
 
     - Engelhard recorded equity in losses of affiliates of $44.8 million as
       follows:
 
     - Engelhard-CLAL continued to face pressures of declining demand for French
       manufactured jewelry, generally due to the availability of inexpensive
       high-quality costume jewelry, and increased competition from other
       international fabricators of precious-metal products with lower cost
       structures. In response to these economic pressures and market
       conditions, Engelhard and its partner, FIMALAC, agreed to rationalize
       certain operations, determined that related assets were impaired and
       reduced those assets to their estimated realizable value. The impact to
       Engelhard of these actions was approximately $30.9 million, the
       components of which were: a valuation allowance provided on deferred tax
       assets of $14.3 million, employee severance of $10.5 million, write off
       of production equipment of $4.3 million and inventory obsolescence
       reserves of $1.8 million. In addition, Engelhard wrote off goodwill of
       $9.0 million related to its investment in the joint venture based on the
       expected future undiscounted cash flows. While market conditions continue
       to reflect the circumstances noted in 1997, as a result of the actions
       taken by Engelhard-CLAL, operating results turned marginally positive in
       1998. Engelhard-CLAL management expects that these actions will be
       substantially completed during 1999.
 
       Management anticipated annual pretax savings of $2 million due to the
       elimination of the losses from this joint venture. The actual pretax
       savings realized during 1998 were $2 million.
 
     - In 1997, Engelhard reached an agreement with its partner, ICC
       Technologies, to restructure Engelhard/ICC, a joint venture in
       desiccant-based, climate-control systems. As a result of this
       restructuring, Engelhard subsequently acquired 100% of Engelhard Hexcore
       L.P., the portion of the former joint venture that focuses on
       manufacturing and marketing desiccant-coated rotors and related products,
       and sold its interest in Fresh Air Solutions L.P. which comprised the
       remainder of the joint venture. Goodwill of $4.9 million related to Fresh
       Air Solutions L.P. was written off as a loss on sale. Management believes
       that this reorganization will allow greater concentration on core
       competencies. This action had been completed prior to the end of 1998.
 
       Management anticipated annual pretax savings of $5 million due to the
       elimination of the losses from this joint venture. The actual pretax
       savings realized during 1998 were $5 million.
 
In summary, the activities covered by these charges yielded pretax savings of
approximately $20 million as a result of lower manufacturing costs for the FCC
catalysts business and the elimination of operating losses for the former
stationary-source, emission-control capital equipment business and the equity
investments, and yielded annual cash savings of approximately $10 million as a
result of lower employee and plant operating costs for the FCC catalysts
business, capital equipment business and the Engelhard/ICC joint venture.
 
PRE-1997 CHARGES
 
The pre-1997 restructuring charges are related to:
 
     - The restructuring of administrative operations at corporate headquarters
       and the process technologies organization;
 
     - The transfer of Attapulgite operations from Engelhard's Attapulgus, GA
       facility to the acquired Quincy, FL site and the associated closing of
       the Attapulgus operations;
 
     - The closure of the Plainville, MA site and the subsequent disposal upon
       the completion of environmental remediation activities;
 
     - The shutdown of operations at an Engelhard facility in Newark, NJ and the
       subsequent disposal of the facility;
 
                                       27
<PAGE>   28
 
     - The shutdown of certain operations of the Union, NJ facility and
       relocation of certain other operations to other underutilized Engelhard
       facilities.
 
   
The employee severance costs associated with the pre-1997 restructuring charges
are primarily related to the restructuring of administrative operations and the
transfer of Attapulgite operations. The severance costs associated with these
actions have been paid over extended periods as certain agreements negotiated
with severed employees provided for payments to be spread over several years.
The pre-1997 restructuring charges originally provided for employee severance
obligations for 1,863 corporate and site employees. The remaining severance
obligation as of December 31, 1998 is primarily attributable to 43 employees.
Additionally, regulatory delays in the consummation of Engelhard's acquisition
of the Quincy, FL attapulgite operation and inherent delays in the completion of
environmental remediation activities at Plainville, MA have extended the payment
periods for those severance costs. Costs of retention of employees for the
longer than expected periods prior to termination have been expensed as
incurred. The remaining severance accrual of $3.6 million at December 31, 1998
is principally for long-term severance payments related to the Union facility
and for severance costs for employees remaining at the Plainville, MA site until
its closure.
    
 
Non-separation related costs associated with the pre-1997 restructuring charges
are primarily for costs associated with the shut down of the Union and Newark,
NJ sites, the Attapulgus, GA attapulgite operations, as well as
non-environmental shut-down costs at the Plainville, MA site. These shut down
costs approximated $15 million during the three year period ended December 31,
1998. The remaining accrual of $2.9 million is primarily for shut-down costs to
be incurred until closure of the Plainville and Union facilities. The timeframe
for final closure of the Plainville facility is pending government approval of
environmental cleanup plans at the site. Additionally, negotiations have begun
for the sale of a portion of the Union facility which, if consummated, will
complete the closure process for that site.
 
The actions related to the Plainville, MA site and the Union, NJ site are
expected to be substantially complete by the end of 2000. Pending resolution of
the matters discussed above, Engelhard believes remaining reserves related to
pre-1997 restructuring activities are adequate for remaining activities under
those plans. No significant incremental savings from the pre-1997 restructurings
were achieved in 1998.
 
The following table sets forth the components of Engelhard's reserves for
restructuring and exit costs:

The non-separation related cash spending for pre-1997 restructuring and exit
cost liabilities for each of the three years ended December 31, 1998, 1997, and
1996 consisted primarily of costs associated with the shut-down of the Union and
Newark, NJ sites, the Attapulgus, GA site and the Plainville, MA site. The
Newark, NJ site was sold in 1998 and had a carrying value of $4.8 million in
1993. The proceeds received in 1998 of $7.1 million related to this facility
have been netted against $4.9 million of cash expenditures in the above
presentation. The remaining balance in the pre-1997 restructuring reserves
consist of shut-down costs for the Union, NJ, Attapulgus, GA and Plainville, MA
sites.
    
 
The non-separation restructuring and exit cost provision made in 1997 consists
primarily of costs associated with the shutdown of the facilities to be closed
in connection with the Process Technologies and Environmental Technologies
actions discussed above, and certain warranty obligations associated with the
sold Environmental Technologies business. Non-separation related cash spending
related to these liabilities for the year ended December 31, 1998 consisted of
payments related to the completion of the shutdown of the facilities and the
satisfaction of any warranty obligations.

GROSS PROFIT
 
Gross profit as a percentage of sales was 16% in 1998 compared to 17% in 1997.
The decrease was driven by the lower margins earned on metal sales by the
Industrial Commodities Management segment. Sales from this segment increased 20%
in 1998 to $2,346.8 million and provided a gross profit of 4% while 1998 sales
from all other segments increased by 9% and provided a gross profit of 31%. As
described in Note 1 to our Consolidated Financial Statements, the lower margins
on Industrial Commodities Management sales are driven by including precious
metals in both sales and cost of sales for certain transactions.
 
SELLING, ADMINISTRATIVE AND OTHER EXPENSES
 
Selling, administrative and other expenses of $337.6 million in 1998 were up
from $327.8 million in 1997 and $255.5 million in 1996. The 1998 amount reflects
the acquisition of the Mallinckrodt businesses in May 1998. The 1997 amount
reflects a full year of Mearl (acquired in May 1996), the impact of the special
and other charges (see "--Special and Other Charges" for detail), a 1996
insurance recovery ($5.7 million after tax or $0.04 per share) and general
growth in our businesses due to new programs and strategic alliances. Selling,
administrative and other expenses as a percentage of sales were 8% in 1998
compared to 9% in 1997. The decrease was driven by higher metal sales by the
Industrial Commodities Management segment. See "--Gross Profit" above. Some
metal sales from this segment do not generate proportionate increases in
underlying selling and administrative expenses. See Note 1 to our Consolidated
Financial Statements.

EQUITY EARNINGS/LOSSES
 
Equity in earnings of affiliates was $10.1 million in 1998, compared with equity
in losses of affiliates of $47.8 million in 1997 and $5.0 million in 1996. The
1997 loss reflects the 1997 special and other charges of $44.8 million related
to Engelhard-CLAL and Engelhard/ICC (see "--Special and Other Charges" for
detail). The increase was also partially attributable to Engelhard-CLAL's
improved operating results and the absence of losses from Engelhard/ICC.
 
GAIN ON SALE OF INVESTMENT
 
In 1996, we sold our share of Heraeus Engelhard Electrochemistry Corporation, a
marketer of electrochemical products. We realized a gain of $2.4 million ($1.5
million after tax or $0.01 per share) on the sale.
 
INTEREST
 
Interest expense was $58.9 million in 1998, compared with $52.8 million in 1997
and $45.0 million in 1996. The 1998 increase primarily reflects the incremental
financing costs associated with acquiring the Mallinckrodt businesses in May
1998. Excluding the impact of financing the acquisition of the Mallinckrodt
businesses, interest expense would have decreased in the current year primarily
due to lower interest rates and a decrease in average debt balances. Higher
interest expense in 1997 and 1996 was primarily due to higher average debt
balances as a result of acquisitions and investments.
 
We capitalized interest of $1.9 million in 1998, $0.7 million in 1997 and $0.9
million in 1996.
 
Interest income, included as a component of net sales, was $2.3 million in 1998,
$1.1 million in 1997 and $1.8 million in 1996.
 
TAXES
 
Income tax expense was $73.5 million in 1998, $38.0 million in 1997 and $59.5
million in 1996. The effective income tax rate was 28.2% in 1998, 29.7% in 1997,
excluding the valuation allowance associated with the 1997 special and other
charges, and 28.3% in 1996. The effective income tax rate was 44.3% in 1997
including the special and other charges.
 
The effective tax rate in 1998 includes a $7.1 million reduction of a valuation
allowance created in 1997 for certain capital loss carryforwards. In 1998,
capital gains were realized on the disposal of certain capital assets. We also
anticipate additional capital gains in 1999 sufficient to fully utilize this
benefit.
 
At year-end 1998, the net deferred tax asset was $106.0 million, primarily for
accrued postretirement and postemployment benefit obligations, the 1997 special
and other charges, the environmental clean-up reserve and other accruals.
Management believes Engelhard will generate sufficient taxable income and employ
tax planning strategies to ensure deferred tax benefits are realized.
 
FINANCIAL CONDITION AND LIQUIDITY
 
Working capital was $89.5 million at December 31, 1998, compared with $15.0
million last year. The increase was primarily due to an increase in accounts
receivable combined with changes in metal related assets and liabilities. The
current ratio was 1.1, compared with 1.0 in 1997. The year-end market value of
our precious-metal inventories exceeded carrying cost by $85.8 million, compared
with $49.7 million last year. The increase in excess value reflects higher
market values which more than offset the impact of slightly reduced levels of
this inventory accounted for under the LIFO method. (See Note 4 to our
Consolidated Financial Statements.)
 
                                       30
<PAGE>   31
 
Our total debt increased to $752.4 million at December 31, 1998, compared with
$622.9 million last year, primarily due to the acquisition of the Mallinckrodt
businesses in May 1998. The ratio of total debt to total capital was 45% at
December 31, 1998, compared with 44% last year.
 
We currently have one $600 million, five-year committed credit facility with a
group of major U.S. and overseas banks. Additional unused, uncommitted lines of
credit available exceeded $670 million at year-end 1998.
 
In July 1998, we filed a shelf registration for $300 million. The net proceeds
from offerings under the shelf registration are expected to be used to retire
short-term debt and for general corporate purposes. We anticipate issuing $100
million of bonds under the shelf registration by mid-1999.
 
Operating activities provided net cash of $176.7 million in 1998, compared with
$196.5 million in 1997 and $24.8 million in 1996. The variance in cash flows
from operating activities primarily occurred in the Industrial Commodities
Management segment (ICM) and reflects changes in metal positions used to
facilitate both supplier and customer requirements. ICM routinely enters into a
variety of arrangements for the sourcing of industrial commodities. Generally,
all such transactions are hedged on a daily basis (see Note 1 to our
Consolidated Financial Statements.) Hedging is accomplished primarily through
forward, future and option contracts. Hedged metal obligations (metal sold not
yet purchased but fully hedged) are considered financing activities and reflect
the fair value of the derivative instruments. These transactions generally cover
the sourcing requirements of ICM. ICM works to ensure that Engelhard and its
customers have an uninterrupted source of industrial commodities utilizing
supply contracts and commodities markets around the world.
 
The cash provided from operations other than the change in metal related assets
and liabilities, exceeded $200 million in 1998 and 1997 and approximated $145
million in 1996.
 
The variance in cash flows from investing activities is primarily due to the
acquisition of the Mallinckrodt businesses in May 1998, partially offset by
proceeds received from the sale and leaseback of our principal executive and
administrative offices in December 1998.
 
The variance in cash flows from financing activities is primarily due to the
issuance in June 1998 of $120 million of our 6.95% bonds due 2028 related to the
acquisition of the Mallinckrodt businesses.
 
Management believes that existing sources of capital, together with cash flows
from operations, will be sufficient to meet foreseeable cash flow requirements.
 
MARKET RISK SENSITIVE TRANSACTIONS
 
We are exposed to market risks arising from adverse changes in interest rates,
foreign currency exchange rates, and commodity prices. In the normal course of
business, we use a variety of techniques and instruments, including derivatives,
as part of our overall risk management strategy. We enter into derivative
agreements with a diverse group of major financial and other institutions with
individually determined credit limits to reduce the risk of nonperformance by
counterparties.
 
INTEREST RATE RISK
 
We use sensitivity analysis to assess the market risk of our debt-related
financial instruments and derivatives. Market risk is defined here as the
potential change in the fair value of debt resulting from an adverse movement in
interest rates. The fair value of our total debt was $750.0 million at December
31, 1998 and $633.5 million at December 31, 1997 based on average market
quotations of price and yields provided by investment banks. A 100 basis point
increase in interest rates could result in a reduction in the fair value of
total debt of $23.0 million at December 31, 1998 compared with $13.9 million at
December 31, 1997.
 
                                       31
<PAGE>   32
 
Also, we use interest rate derivatives to help achieve its fixed and floating
rate debt objectives. As of December 31, 1998, we had two forward treasury lock
agreements with a total notional value of $100 million, both of which were
settled in March 1999. As of December 31, 1997, we had forward starting swaps
with a total notional value of $120 million, each with a start date of April 30,
1998 and termination date of April 30, 2008. These contracts hedged a debt
issuance of $120 million in June 1998.
 
FOREIGN CURRENCY EXCHANGE RATE RISK
 
We use a variety of strategies, including foreign currency forward contracts, to
minimize or eliminate foreign currency exchange rate risk associated with
substantially all of our foreign currency transactions, including metal-related
transactions denominated in other than U.S. dollars. In selected circumstances,
we may enter into foreign currency forward contracts to hedge the U.S. dollar
value of our foreign investments.
 
We use sensitivity analysis to assess the market risk associated with our
foreign currency transactions. Market risk is defined here as the potential
change in fair value resulting from an adverse movement in foreign currency
exchange rates. A 10% adverse movement in foreign currency rates could result in
a net loss of $7.3 million in 1998 compared with $4.7 million in 1997 on our
foreign currency forward contracts; however, since we limit the use of foreign
currency derivatives to the hedging of contractual foreign currency payables and
receivables, this loss in fair value for those instruments would generally be
offset by a gain in the value of the underlying payable or receivable.
 
A 10% adverse movement in foreign currency rates could result in an unrealized
loss of $61.4 million in 1998 compared with $61.3 million in 1997 on our net
investment in foreign subsidiaries and affiliates; however, since we view these
investments as long term, we would not expect such a loss to be realized in the
near term.
 
COMMODITY PRICE RISK
 
Generally, all industrial commodity transactions are hedged on a daily basis
using forward, future or option contracts to substantially eliminate the
exposure to price risk. In addition, all industrial commodity transactions are
marked-to-market daily. In limited and closely monitored situations, for which
exposure levels have been set by senior management, we hold significant unhedged
industrial commodity positions that are subject to future market fluctuations.
Such positions may include varying levels of derivative commodity instruments.
 
We have performed a "value-at-risk" analysis on all of our commodity assets and
liabilities. The "value-at-risk" calculation is a statistical model that uses
historical price and volatility data to predict market risk on a one-day
interval with a 95% confidence level. While the "value-at-risk" models are
relatively sophisticated, the quantitative information generated is limited by
the historical information used in the calculation. For example, the volatility
in the platinum and palladium markets in 1998 and 1997 was greater than
historical norms. Therefore, we use this model only as a supplement to other
risk management tools and not as a substitute for the experience and judgment of
senior management and dealers who have extensive knowledge of the markets and
adjust positions and revise strategies as the markets change. Based on the
"value-at-risk" analysis, the maximum potential one-day loss in fair value was
approximately $2.7 million as of December 31, 1998 compared with $1.1 million as
of December 31, 1997.
 
CAPITAL EXPENDITURES, COMMITMENTS AND CONTINGENCIES
 
Capital projects are designed to maintain capacity, expand operations, improve
efficiency or protect the environment. Capital expenditures amounted to $116.5
million in 1998, $136.9 million in 1997 and $128.2 million in 1996. Capital
expenditures in 1999 are expected to approximate 1998 spending. For information
about commitments and contingencies, see Note 17 and Note 18 to our Consolidated
Financial Statements.
                                       32
<PAGE>   33
 
DIVIDENDS AND CAPITAL STOCK
 
The annualized common stock dividend rate at the end of 1998 and 1997 was $0.40
per share. In the third quarter of 1997, the Board of Directors approved an
11.1% increase in the common stock dividend, raising the level to $0.10 per
share effective September 30, 1997.
 
In the first quarter of 1996, the Board approved the purchase of five million
shares of our common stock. At December 31, 1998, 435,000 shares had been
purchased under this plan.
 
YEAR 2000 UPDATE
 
The ability of computers, software or any equipment utilizing microprocessors to
properly recognize and process data at the turn of the century is commonly
referred to as a Y2K compliance issue. To address this issue, Engelhard has
developed a worldwide Y2K readiness plan that is divided into phases. The phases
are as follows:
 
     -  INVENTORY -- understanding what applications are in the portfolio
 
     -  ASSESSMENT -- determining what, if any, Y2K shortcomings each
        application has
 
     -  REMEDIATION -- fixing or replacing each application to make it Y2K
        compliant
 
     -  TESTING -- conducting thorough Y2K scenarios to ensure that the fixing
        of each application is complete
 
The entire company has completed the inventory and assessment stages. Our major
corporate-wide applications, such as order processing, financials, metals
trading, human resources and payroll, are all complete, including testing.
 
Engelhard has approached its Y2K compliance issue by categorizing its
dependencies into two sections: Internal IT systems, and External systems of
suppliers and customers. Generally, internal systems identified as non-Y2K
compliant will be replaced or modified by reprograming, upgrading or other
means. Many of the internal non-compliant systems were targeted for replacement
for reasons other than Y2K issues as the benefits of newer technology had
already created an economic business case for action. The cost of these
replacement solutions will be capitalized as permitted by applicable accounting
standards whereas the cost of modification solutions will generally be expensed
as repairs. External systems will be monitored with the cooperation of our
suppliers and customers.
 
Internal IT systems -- includes internal applications software such as finance,
manufacturing and logistics. All internal IT systems have been inventoried and
assessed for Y2K compliance.
 
An estimate of completion for individual business unit systems is as follows:

The projects which are either complete or still underway have been primarily
internally planned and staffed. The only major project which used external help
in assessment, remediation, and testing was our corporate order processing
system (CSS), for which we engaged MCI Systemhouse. This is now complete.
 
                                       33
<PAGE>   34
 
A core team in corporate headquarters, including a representative from internal
audit, has been given the responsibility to assess Y2K project progress during
remediation. They also conduct reviews at the end of each major project to
validate Y2K concurrence, according to a pre-determined checklist.
 
   
There has been little in the way of deferral of projects due to Y2K efforts. In
fact, the two major system implementations at corporate (PeopleSoft for Human
Resources and Oracle for Accounts Receivable) were Y2K compliance driven. Both
are now complete.
    
 
There have been no Y2K problems to date. In particular, orders which have been
placed with Y2K delivery have experienced no problem.
 
Internal Non-IT systems--includes embedded chip technology such as programmable
logic controllers and related hardware/software; and personal computers and
related software. Engelhard's programmable logic controllers and related
hardware/software have been inventoried and assessed for Y2K compliance.
Engelhard anticipates that all non-compliant equipment software will be replaced
or upgraded by mid-1999. Engelhard believes that all of its "critical" personal
computers and related software are Y2K compliant. All of Engelhard's other
personal computers and related software are in the process of being remediated
and tested. Engelhard believes that any non-compliant hardware/software will be
replaced or upgraded by mid-1999.
 
   
External systems--includes systems of customers and suppliers. Engelhard is in
the process of understanding the extent to which it is vulnerable to the Y2K
issues of its customers and suppliers. Engelhard has identified and contacted
third parties who would have a significant negative impact on operations if not
Y2K compliant. Engelhard has assessed the status of these third parties and has
developed requisite action where necessary. There can be no assurance that the
Y2K compliance issues of these customers and suppliers will not have a material
adverse affect on operating results or cash flows of Engelhard.
    
 
Engelhard's assessment of its suppliers regarding their Y2K readiness, including
both domestic and international, includes comprehensive surveys of all vendors
and individual assessments of key ones. The surveys are complete and revealed no
major problems. The individual assessments are ongoing through 1999, and will
include face-to-face reviews if appropriate. In Engelhard's communication with
its customers regarding their inquiries to us, we have replied, with a standard
written response which gives our assurance that we are taking the appropriate
steps to be Y2K compliant before January 1, 2000.
 
The estimated total cost of implementing Y2K solutions is approximately $13.1
million. The total amount expended through December 31, 1997 was $0.8 million,
with an additional $9.8 million expended in 1998. With regard to the $10.6
million expended to date, approximately $6.1 million has been expensed and $4.5
million capitalized in accordance with applicable accounting standards. The
remaining Y2K expenditures are estimated to be incurred by the end of 1999, of
which approximately $1.6 million will be expensed.
 
The dates on which Engelhard plans to complete any necessary Y2K modifications
are based on management's best estimates, which were derived utilizing numerous
assumptions of future events, including the continued availability of certain
resources, third-party modification plans and other factors. However, there can
be no assurance that these estimates will be achieved and actual results could
differ materially from those plans. Specific factors that might cause such
material differences include, but are not limited to, the availability of
personnel trained in this area, the ability to locate and correct all relevant
computer codes and similar uncertainties.
 
The failure to correct a material Y2K compliance problem could result in an
interruption in, or a failure of, certain normal business activities or
operations. Such failures could have a material adverse impact on the operations
of Engelhard. Engelhard believes that, with the implementation of new business
systems and completion of the Y2K project as scheduled, the possibility of
significant interruptions of normal operations is reduced.

While we feel that we do not have significant exposure with respect to our major
systems in dealing with Y2K, we have begun to assess areas in which a
contingency plan is prudent in the event of an unforeseen problem.
 
To that end, each business has identified the key systems that require a
contingency plan to be developed. Going forward, the milestones through 1999
are:

EURO
 
On January 1, 1999, eleven of fifteen member countries of the European Union
established fixed conversion rates between their existing currencies ("legacy
currencies") and one common currency--the euro. The euro is traded on currency
exchanges and may be used in business transactions. The conversion to the euro
will eliminate currency exchange rate risk between the member countries.
Beginning in January 2002, new euro-denominated bills and coins will be issued,
and legacy currencies will be withdrawn from circulation. Our operating
subsidiaries affected by the euro conversion have established plans to address
the issues raised by the currency conversion. These issues include, among
others, the need to adapt computer and financial systems, business processes and
equipment, to accommodate euro-denominated transactions and the impact of one
common currency on pricing. Since financial systems and processes currently
accommodate multiple currencies, the plans contemplate conversion by mid-2001 if
not already addressed in conjunction with Y2K remediation. We do not expect the
system and equipment conversion costs to be material. Due to numerous
uncertainties, we cannot reasonably estimate the effects one common currency
will have on pricing and the resulting impact, if any, on our financial
condition or results of operations.
 
JAPAN FRAUD UPDATE
 
In 1998, management learned that we and several other companies operating in
Japan had been victims of a fraudulent scheme involving base-metal inventory
held in third-party warehouses in Japan. The inventory loss was approximately
$40 million in 1997 and $20 million in 1998. We are vigorously pursuing various
recovery actions. These actions include negotiations with the various third
parties involved and in several instances the commencement of litigation. During
1998, we recorded a receivable from the insurance carriers and third parties
involved for approximately $20 million. This amount represents management's and
counsel's best estimate of the minimum probable recovery from the various
insurance policies and other parties involved in the fraudulent scheme.
 
OTHER MATTERS
 
We adopted Statement of Financial Accounting Standards No. 131 "Disclosures
about Segments of an Enterprise and Related Information" in the fourth quarter
of 1998. This statement establishes standards for the way in which public
business enterprises report information about operating segments in annual
financial statements and requires that those enterprises report selected
information about those operating segments in interim reports. It also
establishes standards for related disclosures about products and services,
geographic areas and major customers. The adoption of SFAS 131 did not have an
effect on our financial position or results of operations.
 
We adopted Statement of Financial Accounting Standards No. 132 "Employers'
Disclosures about Pensions and Other Postretirement Benefits" in the fourth
quarter of 1998. This statement
 
                                       35
<PAGE>   36
 
revises employers' disclosures about pension and other postretirement benefit
plans. It does not change the measurement or recognition of those plans. The
adoption of SFAS 132 did not have an effect on our financial position or results
of operations.
 
In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133 "Accounting for Derivative Instruments
and Hedging Activities." SFAS 133 is effective for the Company on January 1,
2000. We will adopt SFAS 133 by the first quarter of 2000. SFAS 133 requires
that all derivative instruments be recorded on the balance sheet at their fair
value. We have not yet determined the impact that the adoption of SFAS 133 will
have on our earnings, comprehensive income or statement of financial position.
 
SUBSEQUENT EVENT
 
In October 1998, Standard & Poor's and Moody's Investors Service each placed its
ratings of our debt on credit watch. The rating action was prompted by our
announcement that we had hired financial advisors to help the Company explore
its strategic alternatives after Minorco announced that it will be divesting its
31.8% interest in Engelhard. In March 1999, Moody's Investors Service confirmed
the A3 ratings on our senior unsecured debt and confirmed our commercial paper
rating at Prime-2. In addition, in March 1999 Standard & Poor's announced that
ratings on Engelhard remain on credit watch, with the implications being revised
to "negative" from "developing". If the transaction is consummated as described
above, Standard & Poor's indicated that it would lower its corporate credit and
senior unsecured debt ratings to single-A minus from single-A and its commercial
paper ratings to A-2 from A-1. These rating actions followed the March 2, 1999
announcement of our purchase of shares of our common stock owned by Minorco.

                                    BUSINESS
 
We are a leading developer and producer of products and systems based on our
expertise in chemistry and other sciences. Our business activities are organized
into five segments: Environmental Technologies, Process Technologies, Paper
Pigments and Additives, Specialty Pigments and Additives, and Industrial
Commodities Management.
 
ENVIRONMENTAL TECHNOLOGIES
 
Our Environmental Technologies segment consists of Automotive Emission Systems
and Emission and Performance Systems, serving the automotive, off-road vehicle,
light and heavy duty truck, aircraft, power generation and process industries.
 
Environmental technology catalysts are used in applications such as the
abatement of carbon monoxide, oxides of nitrogen and hydrocarbons from gasoline,
diesel and alternate fueled vehicle exhaust gases to meet emission control
standards. These catalysts also are used for removal of odors, fumes and
pollutants generated by a variety of process industries, including but not
limited to the painting of automobiles, appliances and other equipment; printing
processes; the manufacture of nitric acid and tires; the curing of polymers; and
power generation sources. In 1997, we dissolved our Metreon joint venture,
formed in 1995 with W. R. Grace, to develop and market metallic substrate
catalytic converters for cars. Also in 1997, we purchased the assets of W. R.
Grace's Camet Metal Monolith business, which manufactures and markets pre-coated
catalyzed metal monoliths for mobile-source applications as well as stationary
nitrogen oxides and carbon dioxide emission-control products.
 
We also participate in the manufacture and supply of automotive emission-control
catalysts through affiliates serving the Asia-Pacific region: N.E. Chemcat
Corporation (Japan)--38.8% owned; and Heesung-Engelhard (South Korea)--49%
owned, both of which also produce other catalysts and products.
 
The products of the Environmental Technologies segment compete in the
marketplace on the basis of cost and value performance. No single competitor is
dominant in the markets in which the Company operates.
 
The manufacturing operations of the Environmental Technologies segment are
carried out in the United States, Germany, India, South Africa and the United
Kingdom with equity investments located in the United States and South Korea.
The products are sold principally through the Company's sales organizations or
those of its equity investments, supplemented by independent distributors and
representatives.
 
The principal raw materials used by the Environmental Technologies segment
include precious metals, procured by the Industrial Commodities Management
segment, and a variety of minerals and chemicals that are generally readily
available.

                                       37
<PAGE>   38
 
These catalysts are used in both batch and continuous operations, that in many
cases, require special catalysts for each application. Chemical catalysts are
based on our proprietary technology and are developed in close cooperation with
specific customers. Sorbents are used to purify and decolorize naturally
occurring fats and oils for manufacture into shortenings, margarines and cooking
oils.
 
On May 1, 1998, we acquired the chemical catalysts businesses of Mallinckrodt
Inc. for approximately $210 million in cash. The acquired businesses produce
custom and licensed polymerization catalysts, base-metal catalysts,
precious-metal catalysts, and maleic-anhydride catalysts and expanded our
existing chemical catalysts businesses.
 
The products of the Chemical Catalysts business compete in the marketplace on
the basis of cost and value performance. No single competitor is dominant in the
markets in which the Company operates.
 
The manufacturing operations of the Chemical Catalysts business are carried out
in the United States, Belgium, Italy and The Netherlands. The products are sold
principally through the Company's sales organizations supplemented by
independent representatives.
 
The principal raw materials used by the Chemical Catalysts business include
metals, procured by the Industrial Commodities Management segment and third
parties, and a variety of minerals and chemicals that are generally readily
available.
 
The principal products of the Petroleum Catalysts business are zeolitic cracking
catalysts widely used by refiners to provide economies in petroleum processing.
We offer a full line of fluid catalytic cracking (FCC) catalysts, many of which
are based on patented technology. These catalysts can be used to separately
control selectivity and cracking activity, which enables catalyst formulations
to be tailored to meet specific refiners' needs.
 
Other catalyst products of the Petroleum Catalysts business are used in
reforming, hydrotreating, isomerization and selective hydrogenation processes in
petroleum refineries to meet increasingly stringent fuel quality requirements.
Silica gel absorbents are used in air drying and natural gas treating.
 
The products of the Petroleum Catalysts business compete in the marketplace on
the basis of cost and value performance. No single competitor is dominant in the

INDUSTRIAL COMMODITIES MANAGEMENT
 
Our Industrial Commodities Management segment purchases and sells precious
metals, base metals and related products. It does so under a variety of pricing
and delivery arrangements structured to meet the logistical, financial and price
risk management requirements of the Company, its customers and suppliers.
Additionally, it offers related services for precious-metals refining and
produces salts and solutions.
 
The Industrial Commodities Management segment is responsible for procuring
precious and base metals to meet the requirements of the Company's operations
and its customers. Supplies of newly mined platinum group metals are obtained
primarily from South Africa and the Russian Federation and to a lesser extent
from the United States and Canada, the only four regions that are known
significant sources. Most of these platinum group metals are obtained pursuant
to a number of contractual arrangements with different durations and terms. Gold
and silver are purchased from various sources. In addition, in the normal course
of business, certain customers and suppliers deposit significant quantities of
precious metals with the Company under a variety of arrangements. Equivalent
quantities of precious metals are returnable as product or in other forms.
 
The Industrial Commodities Management segment also engages in precious and base
metals dealing with industrial consumers, dealers, central banks, miners and
refiners. It also participates in refining of precious metals and the production
of salts and solutions. Offices are located in the United States, Italy, Japan,
Peru, the Russian Federation, Switzerland and the United Kingdom.
 
As of January 1, 1999 the Industrial Commodities Management segment had
approximately 125 employees worldwide.
 
MAJOR CUSTOMERS
 
For the years ended December 31, 1998 and 1997, Ford Motor Company, a customer
of our Environmental Technologies and Industrial Commodities Management
segments, accounted for 18% and 12%, respectively, of our net sales. For the
year ended December 31, 1996, Engelhard-CLAL, a related party and a customer of
our Environmental Technologies and Industrial Commodities Management segments,
accounted for 16% of our net sales. Sales to these customers include both
fabricated products and precious metals and were therefore significantly
influenced by fluctuations in precious-metal prices, as was the quantity and
type of metal purchased. In such cases, market price fluctuations, quantities
and types purchased can result in material variations in sales reported, but do
not usually have a direct or significant effect on earnings.
 
RESEARCH AND PATENTS
 
We currently employ approximately 475 scientists, technicians and auxiliary
personnel engaged in research and development in the field of chemistry and
metallurgy. These activities are conducted in the United States and abroad.
Research and development expense was $69.8 million in 1998, $61.4 million in
1997 and $56.5 million in 1996.
 
Research facilities include fully staffed instrument analysis laboratories,
which we maintain in order to achieve the high level of precision necessary for
our various business groups and to assist customers in understanding how
Engelhard's products and services add value to their businesses.
 
We own or are licensed under numerous patents secured over a period of years. It
is our policy to normally apply for patents whenever we develop new products or
processes considered to be commercially viable and, in appropriate
circumstances, to seek licenses when such products or processes are developed by
others. While we deem our various patents and licenses to be
 
                                       40
<PAGE>   41
 
   
important to certain aspects of our operations, we do not consider any
significant portion of our business as a whole to be materially dependent on
patent protection.
    
 
ENVIRONMENTAL MATTERS
 
With the oversight of environmental agencies, we are currently preparing, have
under review, or are implementing, environmental investigations and cleanup
plans at several currently or formerly owned and/or operated sites, including
Plainville, MA, Salt Lake City, UT and Attapulgus, GA. We are continuing to
investigate contamination at Plainville under a 1993 agreement with the United
States Environmental Protection Agency (EPA) and are awaiting approval of a
decommissioning plan by the State of Massachusetts under authority delegated by
the Nuclear Regulatory Commission. Investigation of the environmental status at
Salt Lake City continues under a 1993 agreement with the Utah Solid and
Hazardous Waste Control Board. An approved reclamation program at the Attapulgus
site, under a 1994 consent order with the Georgia Department of Natural
Resources, Environmental Protection Division, is complete pending final
Department approval.
 
In addition, seven sites have been identified at which we believe liability as a
potentially responsible party (PRP) is probable under the Comprehensive
Environmental Response, Compensation, and Liability Act of 1980, as amended, or
similar state laws (collectively referred to as Superfund) for the cleanup of
contamination resulting from the historic disposal of hazardous substances
allegedly generated by the Company, among others. Superfund imposes strict,
joint and several liability under certain circumstances. In many cases, the
dollar amount of the claim is unspecified and claims have been asserted against
a number of other entities for the same relief sought from the Company. Based on
existing information, we believe that we are a de minimis contributor of
hazardous substances at a number of the sites referenced above. Subject to the
reopening of existing settlement agreements for extraordinary circumstances or
natural resource damages, we have settled a number of other cleanup proceedings.
We have also responded to information requests from EPA and state regulatory
authorities in connection with other Superfund sites.
 
The liabilities for environmental cleanup related costs recorded in the
consolidated balance sheets at December 31, 1998 and 1997 were $39.5 million and
$43.6 million, respectively, including $1.2 million and $3.8 million,
respectively, for Superfund sites. These amounts represent those costs which we
believe are probable and reasonably estimable. Based on currently available
information and analysis, our accrual represents approximately 55% of what we
believe are the reasonably possible environmental cleanup related costs of a
noncapital nature. The estimate of reasonably possible costs is less certain
than the probable estimate upon which the accrual is based.
 
During the past three-year period, cash payments for environmental cleanup
related matters were $4.1 million, $6.0 million and $7.0 million for 1998, 1997
and 1996, respectively. The amounts accrued in connection with environmental
cleanup related matters were not significant over this time period.
 
For the past three-year period, environmental related capital projects have
averaged less than 10 percent of our total capital expenditure programs, and the
expense of environmental compliance, including environmental testing, permits,
consultants and in-house staff, was not material.
 
There can be no assurances that environmental laws and regulations will not
become more stringent in the future or that we will not incur significant costs
in the future to comply with such laws and regulations. Based on existing
information and currently enacted environmental laws and regulations, cash
payments for environmental cleanup related matters are projected to be $8.0
million for 1999, all of which has already been accrued. Further, we anticipate
that the amounts of capitalized environmental projects and the expense of
environmental compliance will approximate current levels. While it is not
possible to predict with certainty, we believe
                                       41
<PAGE>   42
 
that environmental cleanup related reserves at December 31, 1998 are reasonable
and adequate and that environmental matters are not expected to have a material
adverse effect on financial condition. These matters, if resolved in a manner
different from the estimates, could have a material adverse effect on our
operating results or cash flows.
 
LEGAL PROCEEDINGS AND CONTINGENCIES
 
Various lawsuits, claims and proceedings are pending against Engelhard. During
1998, 1997 and 1996, we provided $2.4 million, $2.8 million and $4.3 million,
respectively, for existing legal proceedings.
 
We and certain of our present and former officers have agreed to a stipulation
of settlement of a class action filed in November 1995 which alleged
misstatements and omissions in connection with press releases issued in 1995
concerning our PremAir catalyst systems. In the settlement, which was approved
by the Court on December 8, 1998, in exchange for the dismissal of the complaint
against all defendants, we will pay no more than $7.2 million of a maximum
settlement amount of $21.5 million. The balance of the settlement amount will be
paid by insurance carried by us for such purposes. Because the final settlement
amount will depend on the number of eligible shares of our common stock for
which claims are submitted, the amounts to be paid by us and our insurer could
be less, but in no event more, than the above-stated amounts. This matter, if
resolved in accordance with the stipulation of settlement, will not have a
material adverse effect on our operating results.
 
We are one of a number of defendants in numerous proceedings which allege that
the plaintiffs contracted cancer and/or suffered other injuries from exposure to
talc, asbestos or other "toxic" substances purportedly supplied by us and other
defendants. We are also subject to a number of environmental contingencies and
are a defendant in a number of lawsuits covering a wide range of other matters.
In some of these matters, the remedies sought or damages claimed are
substantial. While it is not possible to predict with certainty the ultimate
outcome of these lawsuits or the resolution of the environmental contingencies,
management believes, after consultation with counsel, that resolution of these
matters is not expected to have a material adverse effect on our financial
condition. These matters, if resolved in a manner different from management's
current expectations, could have a material adverse effect on our operating
results or cash flows. See Note 17 to our Consolidated Financial Statements for
information regarding environmental cleanup costs.
 
In July 1996, the Securities and Exchange Commission issued a formal order of
investigation concerning the sales of our stock by certain of our officers and
directors during 1995. Subpoenas for documents and witness testimony were issued
by the SEC. In response, we provided documents to the SEC and witnesses were
examined by the SEC staff during 1996.
 
In 1998, management learned that we and several other companies operating in
Japan had been victims of a fraudulent scheme involving base-metal inventory
held in third-party warehouses in Japan. The inventory loss was approximately
$40 million in 1997 and $20 million in 1998. We are vigorously pursuing various
recovery actions. These actions include negotiations with the various third
parties involved and in several instances the commencement of litigation. During
1998, we recorded a receivable from the insurance carriers and third parties
involved for approximately $20 million. This amount represents management's and
counsel's best estimate of the minimum probable recovery from the various
insurance policies and other parties involved in the fraudulent scheme.
 
In February 1999, the Peruvian taxing authority made public an investigation of
the country's gold industry stemming from suspected evasion of value-added tax
payments. Engelhard Peru, S.A., a purchaser and exporter of gold, paid the tax
to its vendors for each purchase and then claimed a refund from the Peruvian
taxing authority after export. We typically would post a one-month letter of
credit to obtain a prompt refund. Our refund claims for November and December of
1998 and January of 1999 were approximately $10 million per month. We have
                                       42
<PAGE>   43
 
   
received the refunds for November and December, but, at the request of the
government, the letters of credit, in the amount of $20 million, have been
extended until July 1999 while the investigation is conducted. The refund for
January 1999 is going through the claims procedure and remains unpaid.
Management believes, based upon consultation with counsel, that all appropriate
tax payments have been made and that we are entitled to all refunds claimed.
However, if the resolution of this matter differs from management's belief, the
maximum financial exposure is approximately $30 million. Meanwhile, Engelhard
has suspended any operations that could further increase the value-added tax
exposure pending completion of the industry investigation.

                            THE SELLING STOCKHOLDER
 
Minorco is selling the common stock. Minorco, through Taurus Investments S.A., a
wholly-owned subsidiary of Minorco, holds 45,943,494 shares of common stock of
Engelhard, representing approximately 32% of the outstanding voting securities
of Engelhard.
 
                          DESCRIPTION OF CAPITAL STOCK
General
 
Engelhard is authorized to issue 350,000,000 shares of common stock, par value
$1.00 per share, and 5,000,000 shares of preferred stock, without par value. All
outstanding shares of common stock are fully paid and non-assessable. As of
January 31, 1999, there were 144,645,642 shares of common stock outstanding.
 
Common Stock
 
The holders of the common stock of Engelhard are entitled to receive dividends
from legally available funds when they are declared by the Board of Directors,
subject to the rights of the holders of preferred stock, and are entitled upon
liquidation to share on a proportionate basis in all assets of Engelhard after
claims of creditors of Engelhard and holders of any preferred stock have been
satisfied.
 
The holders of the common stock are entitled to one vote for each share held on
all matters which shareholders are entitled to vote upon. The holders of the
common stock do not have cumulative voting rights, any preferential or
preemptive right with respect to any securities of Engelhard, or any conversion
rights. The common stock is not subject to redemption.
 
The common stock is listed on the following stock exchanges: New York, Chicago
(options), London and the Swiss Electronic Bourse. The transfer agent for the
common stock is ChaseMellon Shareholder Services, L.L.C.
 
Preferred Stock
 
Engelhard is authorized to issue 5,000,000 shares of preferred stock in one or
more series. Engelhard's Board of Directors can fix the rights, preferences and
limitations of each series. If any particular issue of preferred stock has the
right to receive dividends before the common stock, any payments to satisfy
those dividend preferences would reduce the amount of funds available for the
payment of dividends on common stock. Also, holders of preferred stock would
normally be entitled to receive a preference payment before any payment is made
to holders of common stock in the event of any liquidation, dissolution or
winding-up of Engelhard. As of the date of this prospectus, no shares of
preferred stock are issued or outstanding.
 
Supermajority Voting Requirements and Classified Board of Directors
 
Engelhard's restated certificate of incorporation contains restrictions on
business combinations, including by merger, sale, consolidation or through the
issuance of voting securities of Engelhard, with any entity who beneficially
owns 5% or more of the outstanding common stock of Engelhard. At least 80% of
the outstanding shares of common stock must vote to approve a business
combination. The 80% affirmative vote must include at least 50% of the
outstanding shares of common stock held by shareholders other than any such 5%
beneficial owner. A majority of the board of directors of Engelhard could
approve a business combination without the 80% affirmative vote if a majority of
the directors approving the transaction had been
 
                                       46
<PAGE>   47
 
members of the board prior to the time such 5% beneficial owner became the 5%
beneficial owner.
 
Engelhard's restated certificate of incorporation also provides for a classified
board of directors divided into three classes. All classes shall be as nearly
equal in number as possible and no class shall include fewer than two directors,
with one class of directors to be elected each year for a three-year term.
 
Neither provision described in the previous paragraphs can be amended without
the affirmative vote of the holders of at least 80% of the outstanding shares of
common stock. The 80% affirmative vote must include at least 50% of the
outstanding shares of common stock held by shareholders other than a 5%
beneficial owner.
 
Engelhard believes that the classified board and the 80% voting requirements are
desirable to assure continuity in board membership and in policy formulated by
the board. Such provisions are expected to moderate the pace of any change in
control of Engelhard by extending the time required to elect a majority of the
directors and to better enable the board to protect the interests of
shareholders in the event that any person or corporation should attempt to
obtain control of Engelhard.
 
Engelhard recognizes, however, that these provisions could prevent or discourage
a merger, tender offer or proxy contest or attempts to gain control of a large
block of Engelhard securities.
 
The 80% voting requirement for approval of business combinations with 5%
beneficial owners, absent board approval, provides the board and minority
shareholders with a veto power over such transactions. This provision would be
beneficial to Engelhard management when confronted with a hostile tender offer
and may deter such offers, thus depriving a shareholder of the opportunity to
dispose of his or her shares in a hostile tender offer or at a premium to the
market price of the common stock. The deterrence of such offers also has the
effect of supporting existing management in its present position.
 
Shareholder Rights Plan
 
   
On October 1, 1998, our board of directors adopted a stockholder rights plan
declaring a dividend distribution on November 13, 1998 of one right for each
outstanding share of our common stock. Each right entitles the registered
stockholders to purchase from Engelhard one one-thousandth of a share of series
A junior participating preferred stock at a price of $100 per one one-thousandth
of a share.
    
 
Subject to certain exceptions, the rights may not be exercised until 10 days
after:
 
  - a person or group acquires 15% or more of our common stock.
 
  - a person or group announces a tender offer that, if consummated, would
    result in such person or group owning 15% or more of our common stock.
 
If either of these events happen, each holder of a right, other than the person
or group who acquired 15% or more of our common stock, may exercise the right
and receive common stock, or, in certain circumstances, cash, property, or other
securities of Engelhard, having a value equal to two times the purchase price of
the right rather than receiving the series A junior participating preferred
stock.
 
In the event that we are acquired in a merger or other business combination
transaction, or 50% or more of our assets or earning power is sold or
transferred, each holder of a right will have the right to receive common stock
of the acquiring company having a value equal to two times the purchase price of
the right.
 
Subject to certain exceptions, if 15% or more of our common stock is acquired,
the board of directors may exchange the rights, other than the acquirer's rights
which will have become void, in whole or in part, at an exchange ratio of one
share of common stock, or a fraction of a share of preferred stock having the
same market value, per right.
                                       47
<PAGE>   48
 
The rights will expire on October 1, 2008, unless exchanged or redeemed prior to
that date. We may redeem the rights at a price of $.001 per right at any time
prior to the tenth day following a public announcement that a person or group
has acquired 15% or more of our common stock.
 
Until the rights become exercisable, they may be transferred only with the
common stock.
 
The purchase price payable, and the number of shares of series A preferred stock
or other securities or property issuable, upon exercise of the rights are
subject to adjustment to prevent dilution in the event of certain actions taken
by Engelhard.
 
The rights have certain anti-takeover effects. The rights will cause substantial
dilution to a person or group that attempts to acquire Engelhard without
conditioning the offer on a substantial number of rights being acquired. The
rights should not interfere with any merger or other business combination
approved by the board of directors of Engelhard since the board of directors
may, at its option, at any time prior to the time a person has become an
acquiring person, redeem all the then outstanding rights at redemption price of
$.001 per right.
 
Directors' Liability and Indemnification of Directors and Officers
 
Engelhard's restated certificate of incorporation, as amended, provides that no
director of Engelhard will be held personally liable to Engelhard or its
shareholders for monetary damages of any kind for breach of fiduciary duty as a
director, except for liability:
 
(1) for any breach of the director's duty of loyalty to Engelhard or its
shareholders,
 
(2) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law,
 
(3) in respect of certain unlawful dividend payments or stock redemptions or
repurchases in violation of Section 174 of the Delaware General Corporation Law
("DGCL"), or
 
(4) for any transaction from which the director derived an improper personal
benefit.
 
The effect of such provisions in the restated certificate of incorporation will
be to eliminate the rights of Engelhard and its shareholders, including through
shareholders' derivative suits on behalf of Engelhard, to recover monetary
damages against a director for breach of fiduciary duty as a director, including
breaches resulting from negligent or grossly negligent behavior, except in the
situations described in clauses (1) through (4) above.
 
The by-laws of Engelhard provide that each person who was or is made a party or
is threatened to be made a party to or is involved in any actual or threatened
action, suit or proceeding, whether civil, criminal, administrative or
investigative, by reason of the fact that such person is or was a director or
officer of Engelhard or is or was serving at the request of Engelhard as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, whether the basis of such proceeding is
alleged action in an official capacity as a director, officer, employee or agent
or in any other capacity while serving as a director, officer, employee or
agent, shall be indemnified and held harmless by Engelhard to the fullest extent
authorized by the DGCL. This right to indemnification shall also include the
right to be paid by Engelhard the expenses incurred in connection with any such
proceeding in advance of its final disposition to the fullest extent authorized
by the DGCL. This right to indemnification shall be a contract right. Engelhard
may, by action of the board of directors, provide indemnification to such of the
employees and agents of Engelhard to such extent and to such effect as the board
of directors determines to be appropriate and authorized by the DGCL.

</TABLE>
 
The underwriters are offering the shares of common stock subject to their
acceptance of the shares from Minorco and subject to prior sale. The
underwriting agreement provides that the obligations of the several underwriters
to pay for and accept delivery of the shares of common stock offered hereby are
subject to the approval of certain legal matters by their counsel and to certain
other conditions. The underwriters are obligated to take and pay for all of the
shares of common stock offered hereby, if any such shares are taken.
 
The underwriters initially propose to offer part of the shares of common stock
directly to the public at the public offering price set forth on the cover page
hereof and part to certain dealers at a price that represents a concession not
in excess of $0.48 a share under the public offering price. Any underwriter may
allow, and such dealers may reallow, a concession not in excess of $0.10 a share
to other underwriters or to certain dealers. After the initial offering of the
shares of common stock, the offering price and other selling terms may from time
to time be varied by the representatives.
 
Engelhard and certain directors, executive officers and stockholders of
Engelhard, and Minorco, have agreed that, without the prior written consent of
the representatives, on behalf of the underwriters, it will not, during the
period ending 90 days after the date of this prospectus:
 
     (1) offer, pledge, sell, contract to sell, sell any option or contract to
         purchase, purchase any option or contract to sell, grant any option,
         right or warrant to purchase, lend or
 
                                       49
<PAGE>   50
 
         otherwise transfer or dispose of, directly or indirectly, any shares of
         common stock or other securities of Engelhard that are convertible into
         or exchangeable for common stock or
 
     (2) enter into any swap or other ownership arrangement that transfers to
         another, in whole or in part, any of the economic consequences of
         ownership of the common stock, whether any such transaction described
         in clause (1) or (2) above is to be settled by delivery of common stock
         or such other securities, in cash or otherwise.
 
The restrictions described in the above paragraph do not apply to:
 
     (a) the sale of shares of common stock to the underwriters,
 
     (b) in the case of Engelhard, the sale of shares of common stock of
         Engelhard to Engelhard by Minorco,
 
     (c) the issuance by Engelhard of shares of common stock upon the exercise
         of an option or a warrant or the conversion of a security outstanding
         on the date of this prospectus of which the underwriters have been
         advised in writing or
 
     (d) transactions by any person other than Engelhard relating to shares of
         common stock or other securities acquired in open market transactions
         after the completion of the offering of the common stock.
 
In order to facilitate the offering of the common stock, the underwriters may
engage in transactions that stabilize, maintain or otherwise affect the price of
the common stock. Specifically, the underwriters may overallot in connection
with the offering, creating a short position in the common stock for their own
account. In addition, to cover overallotments or to stabilize the price of the
common stock, the underwriters may bid for, and purchase, shares of common stock
in the open market. Finally, the underwriting syndicate may reclaim selling
concessions allowed to an underwriter or a dealer for distributing the common
stock in the offering, if the syndicate repurchases previously distributed
common stock in transactions to cover syndicate short positions, in
stabilization transactions or otherwise. Any of these activities may stabilize
or maintain the market price of the common stock above independent market
levels. The underwriters are not required to engage in these activities, and may
end any of these activities at any time.
 
Engelhard, Minorco and the underwriters have agreed to indemnify each other
against civil liabilities under the Securities Act, including material
misstatements or omissions in this prospectus.
 
In the ordinary course of their respective businesses, certain of the
underwriters and their affiliates have engaged, are engaging and may in future
engage in commercial banking, financial advisory and/or investment banking
transactions with Engelhard and its affiliates for which they have received or
will receive customary compensation.
 
                                 LEGAL MATTERS
 
Cahill Gordon & Reindel (a partnership including a professional corporation) of
New York, New York, will issue an opinion with respect to the validity of the
common stock for Engelhard Corporation. Elvinger, Hoss & Prussen of Luxembourg
and Ben L. Keisler, General Counsel for Minorco, will each act as counsel for
Minorco. Shearman & Sterling of New York, New York will act as counsel for the
Underwriters.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Shareholders and
Board of Directors of Engelhard Corporation:
 
In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of earnings, shareholders' equity and cash flows
appearing on pages F-3 through F-34 present fairly, in all material respects,
the consolidated financial position of Engelhard Corporation and Subsidiaries
(the "Company") as of December 31, 1998 and 1997, and the consolidated results
of operations and their cash flows for each of the three years in the period
ended December 31, 1998, in conformity with generally accepted accounting
principles. These financial statements are the responsibility of the Company's
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these statements in
accordance with generally accepted auditing standards which require that we plan

                             ENGELHARD CORPORATION
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        DECEMBER 31, 1996, 1997 AND 1998
 
NOTE ONE--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
Principles of Consolidation
The accompanying consolidated financial statements include the accounts of
Engelhard Corporation and its wholly-owned subsidiaries (collectively referred
to as Engelhard or the Company). All significant intercompany transactions and
balances have been eliminated in consolidation. Certain prior year amounts have
been reclassified to conform with the current year presentation.
 
Use of Estimates
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.
 
Cash and Cash Equivalents
Cash equivalents include all investments purchased with an original maturity of
three months or less, and have virtually no risk of loss in value.
 
Inventories
Inventories are stated at the lower of cost or market. The elements of cost
include direct labor and materials, variable overhead and the full absorption of
fixed manufacturing overhead. The cost of precious-metals inventories is
determined using the last-in, first-out (LIFO) method of inventory valuation.
The cost of other inventories is principally determined using either the average
cost or the first-in, first-out (FIFO) method.
 
Property, Plant and Equipment
Property, plant, and equipment are stated at cost. Depreciation of buildings and
equipment are provided primarily on a straight-line basis over the estimated
useful lives of the assets. Buildings and building improvements are depreciated
over 20 years, while machinery and equipment is depreciated based on lives
varying from 3 to 10 years. Depletion of mineral deposits and mine development
are provided under the units of production method. When assets are sold or
retired, the cost and related accumulated depreciation is removed from the
accounts and any gain or loss is included in earnings.
 
Intangible Assets
Identifiable intangible assets such as patents and trademarks are amortized
using the straight-line method over their estimated useful lives. Goodwill is
amortized over periods up to 40 years using the straight-line method. The
Company recorded amortization expense of $12.6 million in 1998, $9.6 million in
1997, and $6.3 million in 1996. The accumulated amortization amounted to $34.8
million and $22.2 million at December 31, 1998 and December 31, 1997,
respectively. Included in intangible assets, is net goodwill which amounted to
$300.0 million and $209.4 million at December 31, 1998 and December 31, 1997,
respectively. The increase in net goodwill was primarily the result of the
acquisition of the Mallinckrodt businesses in May 1998. The Company continually
evaluates the reasonableness of its amortization of intangibles. In addition, if
it becomes probable that expected future undiscounted cash flows associated with
intangible assets are less than their carrying value, the assets are written
down to their fair value.

                             ENGELHARD CORPORATION
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
Committed Metal Positions and Hedged Metal Obligations
The Company routinely enters into a variety of arrangements for the sourcing of
industrial commodities. These arrangements are spread among a number of
counterparties, which are generally major industrial companies or highly rated
financial or other institutions. The conduct of this business is closely
monitored.
 
Generally, all industrial commodity transactions are hedged on a daily basis,
using forward, future, option or swap contracts to substantially eliminate the
exposure to price risk. In addition, all industrial commodity transactions are
marked-to-market daily. In limited and closely monitored situations, for which
exposure levels have been set by senior management, the Company holds
significant unhedged industrial commodity positions that are subject to future
market fluctuations. Such positions may include varying levels of derivative
commodity instruments.
 
Committed metal positions (non-inventory metal purchases) and hedged metal
obligations (metal sold not yet purchased but fully hedged) are carried at fair
value. Fair value is generally based on listed market prices. If listed market
prices are not available or if liquidating the Company's positions would
reasonably be expected to impact market prices, fair value is determined based
on other relevant factors, including dealer price quotations and price
quotations in different markets, including markets located in different
geographic areas. Any change in value, realized or unrealized, is recognized in
gross profit in the period of the change.
 
Environmental Costs
In the ordinary course of business, like most other industrial companies, the
Company is subject to extensive and changing federal, state, local and foreign
environmental laws and regulations, and has made provisions for the estimated
financial impact of environmental cleanup related costs. The Company's policy is
to accrue environmental cleanup related costs of a noncapital nature when those
costs are believed to be probable and can be reasonably estimated. Environmental
clean-up costs are deemed probable when litigation has commenced or a claim or
an assessment has been asserted or, based on available information, commencement
of litigation or assertion of a claim or an assessment is probable and based on
available information, it is probable that the outcome of such litigation, claim
or assessment will be unfavorable. The quantification of environmental exposures
requires an assessment of many factors, including changing laws and regulations,
advancements in environmental technologies, the quality of information available
related to specific sites, the assessment stage of each site investigation,
preliminary findings and the length of time involved in remediation or
settlement. For certain matters, the Company expects to share costs with other
parties. The Company does not include anticipated recoveries from insurance
carriers or other third parties in its accruals for environmental liabilities.
 
Revenue Recognition
Revenues are recognized on sales of product at the time the goods are shipped or
when title has passed to the customer. In limited situations, revenue is
recognized on a bill and hold basis as title passes to the customer before
shipment of goods. These bill and hold sales meet the criteria for revenue
recognition. Sales recognized on a bill and hold basis were approximately $10.8
million in 1998, $2.6 million in 1997 and $4.1 million in 1996.
 
The metal component of product sales is recognized at contract price on the date
of title transfer. For all other commodity related activities, an unrealized
gain or loss is recorded based on changes in the market value of the Company's
positions.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
Sales and Cost of Sales
Some of the Company's businesses use precious metals in their manufacturing
processes. Precious metals are included in sales and cost of sales if the metal
has been supplied by the Company. Often, customers supply the precious metals
for the manufactured product. In those cases, precious-metals values are not
included in sales or cost of sales. The mix of such arrangements and the extent
of market price fluctuations can significantly affect the level of reported
sales but do not usually have a material effect on earnings.
 
In addition, sales and purchases of precious metals to/from industrial and
refining customers are transacted through the Company's dealing operations and
are recorded in sales and cost of sales. Secondarily, and usually as a
consequence of the above transactions, the Company also engages in
precious-metals dealing with other counterparties. In these cases, the
precious-metals values are generally included in sales and cost of sales only to
the extent that the Company has added value by changing the physical form of the
metal.
 
Income Taxes
Deferred income taxes reflect the differences between the assets and liabilities
recognized for financial reporting purposes and amounts recognized for tax
purposes. Deferred taxes are based on tax laws as currently enacted.
 
Equity Method of Accounting
The Company's investments in 20% to 50% owned companies in which it has the
ability to exercise significant influence over operating and financial policies
are accounted for using the equity method. Accordingly, the Company's share of
the earnings of these companies is included in consolidated net income.
Investments in other companies are carried at cost.
 
Derivative Instruments
Engelhard enters into foreign exchange contracts as a hedge against monetary
assets and/or liabilities which are denominated in currencies other than the
functional currency of the entity holding those assets or liabilities. The
ultimate maturities of the contracts are timed to coincide with the expected
liquidation of the underlying monetary balances. Gains and losses on the
ultimate settlement of the contracts are offset against the losses and gains
realized on those underlying monetary accounts.
 
Interest rate swaps and similar arrangements are used by Engelhard to lock in
interest rates and/or convert floating rates to fixed and vice versa. The
differential to be paid or received is accrued as interest rates change and is
recognized over the life of the underlying debt agreements.
 
The use of derivative commodity instruments is discussed above under "Committed
Metal Positions and Hedged Metal Obligations." To the extent that the maturities
of these instruments are mismatched, Engelhard may be exposed to cash interest
rates. This exposure is mitigated through use of Eurodollar futures which are
marked to market daily along with the underlying commodity instruments.
 
Stock Option Plans
The Company adopted Statement of Financial Accounting Standards No. 123
"Accounting for Stock-Based Compensation" in 1997. In conjunction with the
adoption, the Company will continue to apply the intrinsic value based method of
accounting prescribed by Accounting Principles Board Opinion No. 25 "Accounting
for Stock Issued to Employees" with pro-forma disclosure of net income and
earnings per share as if the fair value based method prescribed by
 
                                      F-10

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
SFAS 123 had been applied. In general, no compensation cost related to these
plans is recognized in the consolidated statements of earnings.
 
Research and Development Costs
Research and development costs are charged to expense as incurred and were $69.8
million in 1998, $61.4 million in 1997 and $56.5 million in 1996. These costs
are included within selling, administrative and other expenses in the Company's
consolidated statements of earnings.
 
Foreign Currency Translation
The functional currency for the majority of the Company's foreign operations is
the applicable local currency. The translation from the applicable foreign
currencies to U.S. dollars is performed for balance sheet accounts using current
exchange rates in effect at the balance sheet date and for revenue and expense
accounts using a weighted average exchange rate during the period. The resulting
translation adjustments are recorded as a component of shareholders' equity.
Gains or losses resulting from foreign currency transactions are included in the
Company's consolidated statements of earnings.
 
New Accounting Pronouncements
In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133 "Accounting for Derivative Instruments
and Hedging Activities". SFAS 133 is effective for the Company on January 1,
2000. The Company will adopt SFAS 133 by the first quarter of 2000. SFAS 133
requires that all derivative instruments be recorded on the balance sheet at
their fair value. The Company has not yet determined the impact that the
adoption of SFAS 133 will have on its earnings, comprehensive income or
statement of financial position.
 
NOTE TWO--ACQUISITIONS
 
   
On May 1, 1998, the Company acquired the chemical catalyst businesses of
Mallinckrodt Inc. for approximately $210 million in cash. The Company initially
financed the acquisition with a combination of commercial paper and bank
borrowings. The purchase price exceeded the preliminary assessment of the fair
value of net assets acquired by approximately $90 million, which is being
amortized on a straight-line basis over 40 years. The results of the
Mallinckrodt businesses are included in the accompanying financial statements
from the date of acquisition: For the year ended December 31, 1998, the
acquisition increased net sales by $67.7 million; operating earnings by $16.2
million; and earnings per share by $0.04. Earnings per share include the impact
of higher interest expense related to the acquisition.

(1) The 1997 pro forma balances include special and other charges of $149.6
    million ($117.7 million after tax or $0.82 per share).
 
The 1997 amounts above include the Mallinckrodt businesses actual results in
1997. The 1998 amounts above include the Mallinckrodt businesses results for the
first four months of 1998 prior to the acquisition, and the eight months in 1998
postacquisition. The pro forma amounts are based upon certain assumptions and
estimates, and do not reflect any benefit economies that might be achieved from
combined operations. The pro forma results do not necessarily represent results
that would have occurred if the acquisition had taken place on the basis assumed
above, nor are they indicative of the results of future combined operations.
 
On May 31, 1996, the Company acquired the Mearl Corporation (Mearl). Mearl
manufactured and supplied the automotive, cosmetics and industrial markets with
pearlescent pigments, and also manufactured and supplied iridescent film and
other products to a variety of markets. The transaction was accounted for as a
purchase. The purchase price was $272.7 million in cash, financed primarily with
long-term debt. The purchase price exceeded the fair value of net assets
acquired by $153.5 million, which is being amortized on a straight-line basis
over 35 years. The results of operations of Mearl, integrated into the Specialty
Pigments and Additives segment, are included in the accompanying consolidated
financial statements from the date of acquisition.
 
NOTE THREE--SPECIAL AND OTHER CHARGES
 
In response to weak results of certain operations, and as a result of the
base-metal fraud in Japan, Engelhard recorded, in the fourth quarter of 1997,
Special and Other Charges of $149.6 million ($117.7 million after tax).

</TABLE>
 
The 1997 special and other charges are described below:
 
     - The Process Technologies segment incurred charges of $35.4 million
       primarily related to the closure and subsequent sale of a petroleum
       catalysts facility in The Netherlands used for the manufacture of fluid
       catalytic cracking (FCC) catalysts. Management approved a plan to improve
       the profitability of this business, primarily by lowering its cost
       structure and optimizing its manufacturing resources. The most
       significant action resulted in the 1998 sale of the FCC catalysts
       facility in The Netherlands. There was no gain or loss on the sale of the
       facility as the sales price approximated the carrying value as adjusted
       by the special and other charges. This decision was driven by industry
       overcapacity and the determination that Engelhard's European customers
       could be served more efficiently by North American FCC catalysts
       operations. As a result, Engelhard provided for employee severance
       obligations of $6.4 million covering 90 site employees, plant closure and
       other miscellaneous costs of $1.7 million and asset write-downs of $27.3
       million consisting of $22.1 million to reduce the carrying value of the
       facility to an estimate of fair value based on appraisals performed by
       third parties, a $2.7 million reserve for obsolete inventory, and $2.5
       million to write-off intangible assets related to production technology
       which could no longer be utilized. These actions are expected to be
       substantially complete by the end of 1999.
 
     - The Environmental Technologies segment incurred charges of $29.6 million
       related to the sale of the stationary-source, emission-control capital
       equipment business. Management approved a plan to sell this business
       based on unfavorable market growth projections, combined with low
       technological barriers to enter this market. Management believes that
       this strategy will allow Engelhard to concentrate on its core
       competency--catalyst technology. Revenue and operating loss for the
       capital equipment business were $21.6 million and $6.4 million,
       respectively, for the year ended December 31, 1997 and $40.3 million and
       zero, respectively, for the year ended December 31, 1996. Engelhard
       continues to sell catalysts for stationary-source pollution abatement.
       Engelhard provided for losses on contracts and warranty costs of $7.9
       million and reduced the carrying value of goodwill and other assets by
       $21.7 million to an estimate of fair value based on
                                      F-13

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
       negotiations with third parties. This write-down consisted of the
       write-off of goodwill of $15.0 million, a reserve for uncollectable
       accounts receivable of $4.2 million and a reserve for obsolete inventory
       of $2.5 million. The sale was completed in February 1998 and there was no
       gain or loss on the sale of the business as the sales price approximated
       the carrying value as adjusted by the special and other charges. These
       actions are expected to be substantially complete by the end of 1999.
 
     - The Specialty Pigments and Additives segment wrote off assets of
       approximately $0.8 million.
 
     - Japan base-metal fraud of $39.0 million (see Note 18--"Litigation and
       Contingencies" of the Notes to Consolidated Financial Statements of the
       1998 Form 10-K for further detail).
 
     - Engelhard recorded equity in losses of affiliates of $44.8 million as
       follows:
 
      - Engelhard-CLAL continued to face pressures of declining demand for
        French manufactured jewelry, generally due to the availability of
        inexpensive high-quality costume jewelry, and increased competition from
        other international fabricators of precious-metal products with lower
        cost structures. In response to these economic pressures and market
        conditions, Engelhard and its partner, FIMALAC, agreed to rationalize
        certain operations, determined that related assets were impaired and
        reduced those assets to their estimated realizable value. The impact to
        Engelhard of these actions was approximately $30.9 million, the
        components of which were: a valuation allowance provided on deferred tax
        assets of $14.3 million, employee severance of $10.5 million, write off
        of production equipment of $4.3 million and inventory obsolescence
        reserves of $1.8 million. In addition, Engelhard wrote off goodwill of
        $9.0 million related to its investment in the joint venture based on the
        expected future undiscounted cash flows. While market conditions
        continue to reflect the circumstances noted in 1997, as a result of the
        actions taken by Engelhard-CLAL, operating results turned marginally
        positive in 1998. Engelhard-CLAL management expects that these actions
        will be substantially completed during 1999.
 
      - In 1997, Engelhard reached an agreement with its partner, ICC
        Technologies, to restructure Engelhard/ICC, a joint venture in
        desiccant-based, climate-control systems. As a result of this
        restructuring, Engelhard subsequently acquired 100% of Engelhard Hexcore
        L.P., the portion of the former joint venture that focuses on
        manufacturing and marketing desiccant-coated rotors and related
        products, and sold its interest in Fresh Air Solutions L.P., which
        comprised the remainder of the joint venture. Goodwill of $4.9 million
        related to Fresh Air Solutions L.P. was written off as a loss on sale.
        Management believes that this reorganization will allow greater
        concentration on core competencies. This action had been completed prior
        to the end of 1998.
 
PRE-1997 CHARGES
 
The pre-1997 restructuring charges are related to:
 
     - The restructuring of administrative operations at corporate headquarters
       and the process technologies organization;
 
     - The transfer of Attapulgite operations from the Company's Attapulgus, GA
       facility to the acquired Quincy, FL site and the associated closing of
       the Attapulgus operations;
 
     - The closure of the Plainville, MA site and the subsequent disposal upon
       the completion of environmental remediation activities;
 
                                      F-14

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
     - The shutdown of operations at a Company facility in Newark, NJ and the
       subsequent disposal of the facility;
 
     - The shutdown of certain operations of the Union, NJ facility and
       relocation of certain other operations to other underutilized Company
       facilities.
 
The employee severance costs associated with the pre-1997 restructuring charges
are primarily related to the restructuring of administrative operations and the
transfer of Attapulgite operations. The severance costs associated with these
actions have been paid over extended periods as certain agreements negotiated
with severed employees provided for payments to be spread over several years.
The pre-1997 restructuring charges originally provided for employee severance
obligations for 1,863 corporate and site employees. The remaining severance
obligation as of December 31, 1998 is primarily attributable to 43 employees.
Additionally, regulatory delays in the consummation of the Company's acquisition
of the Quincy, FL attapulgite operation and inherent delays in the completion of
environmental remediation activities at Plainville, MA. have extended the
payment periods for those severance costs. Costs of retention of employees for
the longer than expected periods prior to termination have been expensed as
incurred. The remaining severance accrual of $3.6 million at December 31, 1998
is principally for long-term severance payments related to the Union facility
and for severance costs for employees remaining at the Plainville, MA site until
its closure.
 
Non-separation related costs associated with the pre-1997 restructuring charges
are primarily for costs associated with the shut down of the Union and Newark,
NJ sites, the Attapulgus, GA attapulgite operations, as well as
non-environmental shut-down costs at the Plainville, MA site. These shut down
costs approximated $15 million during the three year period ended December 31,
1998. The remaining accrual of $2.9 million is primarily for shut-down costs to
be incurred until closure of the Plainville and Union facilities. The timeframe
for final closure of the Plainville facility is pending government approval of
environmental cleanup plans at the site. Additionally, negotiations have begun
for the sale of a portion of the Union facility which, if consummated, will
complete the closure process for that site.
 
The actions related to the Plainville, MA site and the Union, NJ site are
expected to be substantially complete by the end of 2000.
 
Pending resolution of the matters discussed above, the Company believes
remaining reserves related to pre-1997 restructuring activities are adequate for
remaining activities under those plans.

</TABLE>
 
The non-separation related cash spending for pre-1997 restructuring and exit
cost liabilities for each of the three years ended December 31, 1998, 1997, and
1996 consisted primarily of costs associated with the shut-down of the Union and
Newark, NJ sites, the Attapulgus, GA site and the Plainville, MA site. The
Newark NJ site was sold in 1998 and had a carrying value of $4.8 million in
1993. The proceeds received in 1998 of $7.1 million related to this facility
have been netted against $4.9 million of cash expenditures in the above
presentation. The remaining balance in the pre-1997 restructuring reserves
consist of shut-down costs for the Union, NJ, Attapulgus, GA and Plainville, MA
sites.
 
The non-separation restructuring and exit cost provision made in 1997 consists
primarily of costs associated with the shutdown of the facilities to be closed
in connection with the Process Technologies and Environmental Technologies
actions discussed above, and certain warranty obligations associated with the
sold Environmental Technologies business. Non-separation related cash spending
related to these liabilities for the year ended December 31, 1998 consisted of
payments related to the completion of the shutdown of the facilities and the
satisfaction of any warranty obligations.

All precious-metals inventories are stated at LIFO cost. The market value of the
precious-metals inventories exceeded cost by $85.8 million and $49.7 million at
December 31, 1998 and 1997, respectively. Net earnings include after-tax gains
of $4.9 million in 1998, $2.0 million in 1997, and $3.3 million in 1996 from the
sale of inventory accounted for under the LIFO method.
 
In the normal course of business, certain customers and suppliers deposit
significant quantities of precious metals with the Company under a variety of
arrangements. Equivalent quantities of precious metals are returnable as product
or in other forms.

Mineral deposits and mine development consist of industrial mineral reserves
such as kaolin, attapulgite and mica. The Company does not own any mining
reserves or conduct any mining operations with respect to platinum, palladium or
other metals.
 
In December 1998, the Company entered into a sale-leaseback transaction for
property that served as the principal executive and administrative offices of
the Company and its operating businesses. The gain on the transaction was
approximately $15.3 million and is being amortized over the twenty-year term of
the lease.
 
The Company capitalized interest of $1.9 million in 1998, $0.7 million in 1997
and $0.9 million in 1996.
 
NOTE SIX--INVESTMENTS
 
The Company has investments in affiliates that are accounted for on the equity
method. The more significant of these investments are Engelhard-CLAL and N.E.
Chemcat Corporation (N.E. Chemcat). Engelhard-CLAL, a 50% joint venture,
manufactures and markets certain products containing precious metals. N.E.
Chemcat is a 38.8% owned, publicly-traded Japanese corporation and a leading
producer of automotive and chemical catalysts, electronic chemicals and other
precious-metals-based products.
 
At December 31, 1998 and 1997, the quoted market value of the Company's
investment in N.E. Chemcat was approximately $66 million and $56 million,
respectively. The valuation represents a mathematical calculation based on the
closing quotation published by the Tokyo over-the-counter market and is not
necessarily indicative of the amount that could be realized upon sale.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
Due to the recent weakness of the Japanese equity markets, the Company's
investment in N.E. Chemcat exceeded the quoted market values by $3.7 million and
$17.9 million as of December 31, 1998 and 1997, respectively. Management
believes this situation to be temporary.

NOTE EIGHT--FINANCIAL INSTRUMENTS
 
The Company's nonderivative financial instruments consist primarily of cash in
banks, temporary investments, accounts receivable and debt. The fair value of
financial instruments in working capital approximates book value. The fair value
of long-term debt was $495.9 million in 1998 and $384.1 million in 1997 based on
current interest rates, compared with a book value of $497.4 million in 1998 and
$373.6 million in 1997.
 
The Company believes that its financial instruments do not represent a
concentration of credit risk because the Company deals with a variety of major
banks worldwide, and its accounts receivable are spread among a number of major
industries, customers and geographic areas. In addition, a centralized credit
committee reviews significant credit transactions and risk management issues
before the granting of credit and an appropriate level of reserves is
maintained. For the past three-year period, provisions to these reserves were
not significant.
 
Foreign Currency Instruments
Aggregate foreign transaction gains and losses were not significant for any year
presented. The following table sets forth, in U.S. dollars, the Company's open
foreign currency forward contracts used for hedging other than metal-related
transactions (see Note 7, "Metal Positions and

None of these contracts exceeds a year in duration and the net amount of
deferred income and expense on foreign currency forward contracts had no impact
on financial position or results of operations in 1998, 1997 and 1996.
 
Interest Rate Instruments
In 1998, the Company entered into two treasury lock agreements which were
settled in March 1999.
 
In 1997, the Company entered into five forward starting swaps commencing in
1998, which were closed concurrent with the debt issuance.
 
In 1996, in connection with the $150 million 7% Notes due 2001 and the $100
million 7.375% Notes due 2006, the Company entered into ten forward starting
swaps, which were closed concurrent with the debt issuance. The resulting impact
on the weighted-average interest rate for 1998 and 1997 was not material.
 
The Company entered into an interest rate swap agreement in 1993 to change
certain fixed rate debt into floating rate debt. The impact of this swap
contract, which terminated in 1996, was to increase interest expense by $0.6
million in 1996.
 
NOTE NINE--SHORT-TERM BORROWINGS AND LONG-TERM DEBT
 
At December 31, 1998, the Company had an unsecured committed revolving credit
agreement for $600 million with a group of North American money center banks and
major foreign banks which expires in the year 2002. In connection with its
credit facility, the Company has agreed to certain covenants, none of which is
considered restrictive to the operations of the Company. Facility fees are paid
to the bank group for this line.
 
At December 31, 1998 and 1997, short-term bank borrowings were $185.0 million
and $164.2 million, respectively. Weighted-average interest rates were 5.5%,
5.9% and 5.7% during 1998, 1997 and 1996, respectively. At December 31, 1998 and
1997, long-term debt due within one year was $5.0 million and $0.2 million,
respectively.

against the capital loss carryforwards expected to be generated by some of these
charges. In 1998, the Company disposed of certain capital assets and thereby
realized capital gains. The Company also anticipates that additional capital
gains will be realized in 1999. Therefore, the valuation allowance recorded in
1997 against the capital loss carryforwards was reduced in 1998 by $7.1 million.
 
As of December 31, 1998, the Company had approximately $17.6 million of
nonexpiring alternative minimum tax credit carryforwards available to offset
future U.S. federal income taxes. Also, as of December 31, 1998, the Company had
approximately $3.8 million of domestic capital loss carryforwards expiring in
2003 and approximately $5.4 million of foreign investment tax credits expiring
in 2000 available to offset certain future foreign income taxes. Management
believes that the Company will generate sufficient taxable income and employ tax
planning strategies to ensure realization of these tax benefits.

expense and the expense computed at the federal statutory rate is shown in the

At December 31, 1998, the Company's share of the cumulative undistributed
earnings of foreign subsidiaries was approximately $259.2 million. No provision
has been made for U.S. or additional foreign taxes on the undistributed earnings
of foreign subsidiaries because such earnings are expected to be reinvested
indefinitely in the subsidiaries' operations. It is not practical to estimate
the amount of additional tax that might be payable on these foreign earnings in
the event of distribution or sale; however, under existing law, foreign tax
credits would be available to substantially reduce, or in some cases eliminate,
U.S. taxes payable.
 
NOTE ELEVEN--RELATED PARTY TRANSACTIONS

$17.5 million in 1998, $16.3 million in 1997 and $37.7 million in 1996. At
December 31, 1998 and 1997, amounts due to such entities totaled $8.6 million

NOTE TWELVE--BENEFITS
 
The Company has domestic and foreign pension plans covering substantially all
employees. Plans covering most salaried employees generally provide benefits
based on years of service and the employee's final average compensation. Plans
covering most hourly bargaining unit members generally provide benefits of
stated amounts for each year of service. The Company makes contributions to the
plans as required and to such extent contributions are currently deductible for
tax purposes. Plan assets primarily consist of listed stocks and fixed income
securities.
 
The following table sets forth the plans' funded status:

in 1998. The aggregate fair value of assets for those plans with ABO's in excess
of plan assets is $28.2 million in 1998.
 
The Company also sponsors three savings plans covering certain salaried and
hourly paid employees. The Company's contributions, which may equal up to 50% of
certain employee contributions, were $3.2 million in 1998, $2.9 million in 1997
and $2.4 million in 1996.
 
The Company also currently provides postretirement medical and life insurance
benefits to certain retirees (and their spouses), certain disabled employees
(and their families) and spouses of certain deceased employees. Substantially
all U.S. salaried employees and certain hourly paid employees are eligible for
these benefits, which are paid through the Company's general health care and
life insurance programs, except for certain medicare-eligible salaried and
hourly retirees who are provided a defined contribution towards the cost of a
partially insured health plan. In addition, the Company provides postemployment
benefits to former or inactive employees after employment but before retirement.
These benefits are substantially similar to the postretirement benefits but
cover a much smaller group of employees.
 
The following table sets forth the components of the accrued postretirement and
postemployment benefit obligation, all of which are unfunded:

The weighted-average discount rate used in determining the actuarial present
value of the accumulated postretirement and postemployment benefit obligation
for 1998 is 6.75%. The average assumed health care cost trend rate used for 1998
is 8%, gradually decreasing to 5% by 2005. A 1% increase in the assumed health
care cost trend rate would have increased aggregate service and interest cost in
1998 by $0.8 million and the accumulated postretirement and postemployment
benefit obligation as of December 31, 1998 by $6.6 million. A 1% decrease in the
assumed healthcare cost trend rate would have decreased aggregate service and
interest cost in 1998 by $1.3 million and the accumulated postretirement and
postemployment benefit obligation as of December 31, 1998 by $11.1 million.
 
NOTE THIRTEEN--STOCK OPTION AND BONUS PLANS
 
The Company's Stock Option Plans of 1991 and 1981, as amended (the Key Option
Plans) generally provide for the granting to key employees of options to
purchase an aggregate of 16,875,000 and 6,834,375 common shares, respectively,
at fair market value on the date of grant. No options under the Key Option Plans
may be granted after June 30, 2001.
 
In 1993, the Company established the Employee Stock Option Plan of 1993, as
amended, which generally provided for the granting to all employees (excluding
U.S. bargaining unit employees and key employees eligible under the Key Option
Plans) of options to purchase an aggregate of 2,812,500 common shares at fair
market value on the date of grant. No additional options may be granted under
this plan. In 1995, the Company established the Directors Stock Options Plan,
which generally provides for the granting to each nonemployee director the
option to purchase up to 3,000 common shares at the fair market value on the
date of grant. Options under all plans become exercisable in four installments
beginning after one year, and no options may be exercised after 10 years from
the date of grant. Outstanding options may be canceled and reissued under terms
specified in the plan documents.
 
Had compensation cost for the Company's two stock option plans been determined
based on the fair value at grant date for awards in 1998, 1997 and 1996

The pro forma amounts shown above are not representative of the effects on net
earnings or earnings per share in future years because only options granted
after January 1, 1995 have been included in the above numbers, and the full net
earnings effect is recognized over the vesting period, typically four years. The
weighted-average fair value at date of grant for options granted during 1998,
1997 and 1996 was $5.07, $5.74 and $7.37, respectively. Fair value of each
option grant is estimated on the date of grant using the Black-Scholes
option-pricing model. The following assumptions were used for option grants in
1998, 1997 and 1996: dividend yield of 1.3% to 2.3%, expected volatility of 31%
to 32%; risk free interest rate of 4.5% to 6.5%; and expected life of 4 to 5
years.

The Company's Key Employee Stock Bonus Plan, as amended (the Bonus Plan)
provides for the award of up to 15,187,500 common shares to key employees as
compensation for future services, not exceeding 1,518,750 shares in any year
(plus any canceled awards or shares available for award, but not previously
awarded). The Bonus Plan terminates on June 30, 2006. Shares awarded vest in
five annual installments, provided the recipient is still employed by the
Company on the vesting date. Compensation value is measured on the date the
award is granted. In 1998 and 1997, the Company granted 197,000 and 193,000
shares to key employees at a fair value of $17.54 and $20.25, respectively, per
share.
 
Compensation expense relating to stock awards was $3.9 million in 1998, $5.2
million in 1997 and $7.0 million in 1996. Shares awarded, net of cancellations,
are included in average shares outstanding.
 
Engelhard has certain deferred compensation arrangements where shares earned
under the Engelhard stock bonus plan are deferred and placed in a "Rabbi Trust".
Under certain conditions, the plan permits the employees to convert their
deferred stock balance to deferred cash. In the third quarter of 1998, the
Company adopted the provisions of Emerging Issues Task Force ("EITF") 97-14
"Accounting for Deferred Compensation Arrangements Where Amounts Earned Are Held
in a Rabbi Trust and Invested". This EITF requires Engelhard to consolidate into
its financial statements the net assets of the trust. The impact to the third
quarter, 1998 consolidated financial statements was a $20.1 million increase in
treasury stock (measured at historical cost); the recording of a $23.7 million
deferred compensation obligation (measured on the reporting date by fair value
of the Engelhard common stock held in the trust on behalf of the employees); and
a charge to equity for the $3.6 million difference (referred to as the
"transition differential"). After the transition date but prior to final
settlement, increases/ decreases in the deferred compensation liability will be
recognized (1) in equity to the extent that the share price change falls within
the transition differential, or (2) in income to the extent that the share
change falls outside the transition differential.
 
During the fourth quarter of 1998, the Company recognized a charge to expense of
$2.4 million as a result of an increase in the stock price from $17.69 at
September 30, 1998 to $19.50 at December 31, 1998. For the year ended December
31, 1998, the total charge to expense as a result of adopting EITF 97-14 was
$2.4 million. The total value of the Rabbi Trust at December 31, 1998 was $26.1
million.

and 1,757,223 (at a price range of $22.38 to $23.88) were outstanding at the end
of 1998, 1997 and 1996, respectively, but were not included in the computation
of diluted EPS because the options' exercise prices were greater than the
average annual market price of the common shares. Shares held in the Rabbi Trust
were included in basic and diluted shares outstanding until adoption of EITF
97-14 (as of September 30, 1998) at which point they were considered treasury
stock and excluded from basic shares outstanding.
 
NOTE FIFTEEN--BUSINESS SEGMENT AND GEOGRAPHIC AREA DATA
 
The Company adopted SFAS No. 131 "Disclosures about Segments of an Enterprise
and Related Information" in the fourth quarter of 1998. SFAS No. 131 requires a
new basis of determining reportable business segments, i.e., the management
reporting approach. This approach designates the Company's internal
organizational structure as used by management for making operating decisions
and assessing performance, as the source of business segments. On this basis,
the Company has five reportable business segments: Environmental Technologies,
Process Technologies, Paper Pigments and Additives, Specialty Pigments and
Additives, and Industrial Commodities Management. Segment results, as well as
selected geographic data, are presented on this new basis in 1998, as well as
1997 and 1996.
 
Items that are allocated to the segment results include various corporate
overhead charges such as expenses for information technology, research and
development, and site management. Unallocated items include interest expense,
royalty income, sale of inventory accounted for under the LIFO method, special
and other charges and other miscellaneous Corporate items.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
The Environmental Technologies segment, located principally in the United
States, Europe and South Africa, develops and markets sophisticated
emission-control technologies and systems that enable customers to cost
effectively meet stringent environmental regulations.
 
The Process Technologies segment, located principally in the United States and
Europe, enables customers to improve the productivity, efficiency, environmental
compliance and safety of their processes through advanced chemical and
polymerization catalysts, sorbents and separation products and related
manufacturing expertise. In addition, the segment manufactures advanced cracking
and hydroprocessing technologies that enable petroleum refiners to more
efficiently produce gasoline, transportation fuels and heating oils.
 
The Paper Pigments and Additives segment, located principally in the United
States, Finland and Japan, provides kaolin-based performance products used as
coating and extender pigments by the paper industry. These pigments provide the
opacity, brightness, gloss and printability in paper products.
 
The Specialty Pigments and Additives segment, located principally in the United
States and South Korea, provides functional additives to customers in a broad
array of markets including coatings, plastics, cosmetics and construction. The
segment also provides iridescent films used in a variety of creative, decorative
and packaging applications. These products help customers improve the look,
performance and overall cost of their products.
 
The Industrial Commodities Management segment, located principally in the United
States, Europe and Japan, purchases and sells precious metals, base metals and
related products. It does so under a variety of pricing and delivery
arrangements structured to meet the logistical, financial and price risk
management requirements of the Company, its customers and suppliers.
Additionally, it offers related services for precious-metals refining and
produces salts and solutions.
 
Within the "All Other" category, sales to external customers are primarily from
the Engineered Materials business; operating earnings/(losses) are derived
primarily from the Engineered Materials business, the sale of inventory
accounted for under the LIFO method, royalty income and other miscellaneous
income and expense items not related to the reportable segments.

For the year ended December 31, 1996, Engelhard-CLAL, a related party and a
customer of the Environmental Technologies and Industrial Commodities Management
segments, accounted for approximately $513 million (16%) of the Company's net
sales.
 
Ford Motor Company, a customer of the Environmental Technologies and Industrial
Commodities Management segments, accounted for approximately $731 million (18%)
of the Company's net sales in 1998 and approximately $443 million (12%) of the
Company's net sales in 1997.
 
NOTE SIXTEEN--LEASE COMMITMENTS

Rental/lease expense, including all leases, amounted to $10.7 million in 1998,
$9.2 million in 1997 and $11.8 million in 1996. In December 1998, the Company
entered into a sales-leaseback transaction for property that served as the
principal executive and administrative offices of the Company and its operating
businesses. The term of the lease is twenty years.
 
NOTE SEVENTEEN--ENVIRONMENTAL COSTS
 
With the oversight of environmental agencies, the Company is currently
preparing, has under review, or is implementing, environmental investigations
and cleanup plans at several currently or formerly owned and/or operated sites,
including Plainville, MA, Salt Lake City, UT and Attapulgus, GA. The Company is
continuing to investigate contamination at Plainville under a 1993 agreement
with the United States Environmental Protection Agency (EPA) and is awaiting
approval of a decommissioning plan by the State of Massachusetts under authority
delegated by the Nuclear Regulatory Commission. Investigation of the
environmental status at the Salt Lake City site continues under a 1993 agreement
with the Utah Solid and Hazardous Waste Control Board. An approved reclamation
program at the Attapulgus site, under a 1994 consent order with the Georgia
Department of Natural Resources, Environmental Protection Division, is complete
pending final Department approval.
 
In addition, seven sites have been identified at which the Company believes
liability as a potentially responsible party (PRP) is probable under the
Comprehensive Environmental Response, Compensation, and Liability Act of 1980,
as amended, or similar state laws (collectively referred to as Superfund) for
the cleanup of contamination resulting from the historic disposal of hazardous
substances allegedly generated by the Company, among others. Superfund imposes
strict, joint and several liability under certain circumstances. In many cases,
the dollar amount of the claim is unspecified and claims have been asserted
against a number of other entities for the same relief sought from the Company.
Based on existing information, the Company believes that it is a de minimis
contributor of hazardous substances at a number of the sites referenced above.
Subject to the reopening of existing settlement agreements for extraordinary
circumstances or natural resource damages, the Company has settled a number of
other cleanup proceedings. The Company has also responded to information
requests from EPA and state regulatory authorities in connection with other
Superfund sites.
 
The liabilities for environmental cleanup related costs recorded in the
consolidated balance sheets at December 31, 1998 and 1997 were $39.5 million and
$43.6 million, respectively, including $1.2 million and $3.8 million,
respectively, for Superfund sites. These amounts represent those costs which the
Company believes are probable and reasonably estimable. Based on currently
available information and analysis, the Company's accrual represents
approximately 55% of what it believes are the reasonably possible environmental
cleanup related costs of a noncapital nature. The estimate of reasonably
possible costs is less certain than the probable estimate upon which the accrual
is based.
 
During the past three-year period, cash payments for environmental cleanup
related matters were $4.1 million, $6.0 million and $7.0 million for 1998, 1997
and 1996, respectively. The amounts accrued in connection with environmental
cleanup related matters were not significant over this time period.
 
For the past three-year period, environmental related capital projects have
averaged less than 10 percent of the Company's total capital expenditure
programs, and the expense of environmental compliance (e.g. environmental
testing, permits, consultants and in-house staff) was not material.

                             ENGELHARD CORPORATION
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
There can be no assurances that environmental laws and regulations will not
become more stringent in the future or that the Company will not incur
significant costs in the future to comply with such laws and regulations. Based
on existing information and currently enacted environmental laws and
regulations, cash payments for environmental cleanup related matters are
projected to be $8.0 million for 1999, all of which has already been accrued.
Further, the Company anticipates that the amounts of capitalized environmental
projects and the expense of environmental compliance will approximate current
levels. While it is not possible to predict with certainty, management believes
that environmental cleanup related reserves at December 31, 1998 are reasonable
and adequate and that environmental matters are not expected to have a material
adverse effect on financial condition. These matters, if resolved in a manner
different from the estimates, could have a material adverse effect on operating
results or cash flows.
 
NOTE EIGHTEEN--LITIGATION AND CONTINGENCIES
 
Various lawsuits, claims and proceedings are pending against the Company. During
1998, 1997 and 1996, the Company provided $2.4 million, $2.8 million and $4.3
million, respectively, for existing legal proceedings.
 
The Company and certain of its present and former officers have agreed to a
Stipulation of Settlement ("Stipulation") of a class action filed in November
1995 which alleged misstatements and omissions in connection with press releases
issued in 1995 concerning the Company's PremAir(TM) catalyst systems. In the
settlement, which was approved by the Court on December 8, 1998, in exchange for
the dismissal of the complaint against all defendants, the Company will pay no
more than $7.2 million of a maximum settlement amount of $21.5 million. The
balance of the settlement amount will be paid by insurance carried by the
Company for such purposes. Because the final settlement amount will depend on
the number of eligible shares of the Company's common stock for which claims are
submitted, the amounts to be paid by the Company and the insurer could be less
(but in no event more) than the above-stated amounts. This matter, if resolved
in accordance with the Stipulation, will not have a material adverse effect on
the operating results of the Company.
 
The Company is one of a number of defendants in numerous proceedings which
allege that the plaintiffs contracted cancer and/or suffered other injuries from
exposure to talc, asbestos or other "toxic" substances purportedly supplied by
the Company and other defendants. The Company is also subject to a number of
environmental contingencies (see Note 17, "Environmental Costs" of the Notes to
Consolidated Financial Statements) and is a defendant in a number of lawsuits
covering a wide range of other matters. In some of these matters, the remedies
sought or damages claimed are substantial. While it is not possible to predict
with certainty the ultimate outcome of these lawsuits or the resolution of the
environmental contingencies, management believes, after consultation with
counsel, that resolution of these matters is not expected to have a material
adverse effect on financial condition. These matters, if resolved in a manner
different from management's current expectations, could have a material adverse
effect on the operating results or cash flows.
 
In July 1996, the Securities and Exchange Commission (SEC) issued a formal order
of investigation concerning the sales of Engelhard stock by certain of the
Company's officers and directors during 1995. Subpoenas for documents and
witness testimony were issued by the SEC. In response, the Company provided
documents to the SEC and witnesses were examined by the SEC staff during 1996.

                             ENGELHARD CORPORATION
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
In 1998, management learned that Engelhard and several other companies operating
in Japan had been victims of a fraudulent scheme involving base-metal inventory
held in third-party warehouses in Japan. The inventory loss was approximately
$40 million in 1997 and $20 million in 1998. The Company is vigorously pursuing
various recovery actions. These actions include negotiations with the various
third parties involved and in several instances the commencement of litigation.
During 1998, Engelhard recorded a receivable from the insurance carriers and
third parties involved for approximately $20 million. This amount represents
management's and counsel's best estimate of the minimum probable recovery from
the various insurance policies and other parties involved in the fraudulent
scheme.
 
In February 1999, the Peruvian taxing authority made public an investigation of
the country's gold industry stemming from suspected evasion of value-added tax
payments. Engelhard Peru, S.A., a purchaser and exporter of gold, has paid the
tax to its vendors for each purchase and then claimed a refund from the Peruvian
taxing authority after export. Engelhard typically would post a one-month letter
of credit to obtain a prompt refund. Engelhard's refund claims for November and
December of 1998 and January of 1999 were approximately $10 million per month.
Engelhard has received the refunds for November and December, but, at the
request of the government, the letters of credit, in the amount of $20 million,
have been extended until July 1999 while the industry investigation is
conducted. The refund for January 1999 is going through the claim procedure and
remains unpaid. Management believes, based upon consultation with counsel, that
all appropriate tax payments have been made and that the Company is entitled to
all refunds claimed. However, if the resolution of this matter differs from
management's belief, the maximum financial exposure is approximately $30
million. Meanwhile, the Company has suspended any operations that could further
increase the value-added tax exposure pending completion of the industry
investigation.

NOTE TWENTY--SUBSEQUENT EVENT
 
On March 2, 1999, Engelhard Corporation announced that it has reached an
agreement to purchase approximately 18 million shares of Engelhard stock owned
by Minorco, with the remainder of Minorco's 31.8% stake (approximately 28
million shares) to be sold through an underwritten public offering. Engelhard
has filed a shelf registration on Form S-3 for those 28 million shares.
 
Minorco, a Luxembourg-based company, previously announced its intention to
divest its 31.8% interest in Engelhard prior to the combination of its
businesses with those of Anglo American Corporation of South Africa Limited,
which is expected to occur by the end of May 1999.
 
Under terms of the agreement, Engelhard will purchase approximately 18 million
shares at $18.90 per share or the price received by Minorco in the secondary
offering less the underwriting spread, whichever is lower. Engelhard also has
agreed to purchase up to an additional two million shares if available at the
end of the offering. The 20 million shares represent 13.9% of Engelhard's total
shares outstanding. In addition, Minorco will compensate Engelhard for the costs
and expenses incurred in connection with the transaction.
 
Engelhard anticipates initially financing the purchase with short-term debt and
intends to take steps to reduce its total debt going forward. It is reviewing
its portfolio to identify non-core assets and businesses for potential sale and
exploring ways to further reduce operating expenses.
 
Engelhard's purchase of shares and the secondary offering are expected to be
completed during the second quarter of 1999.
 
In October 1998, Standard & Poor's and Moody's Investors Service each placed its
ratings of Engelhard Corporation debt on credit watch. The rating action was
prompted by Engelhard's announcement that it had hired financial advisors to
help the Company explore its strategic alternatives after Minorco announced that
it will be divesting its 31.8% interest in Engelhard Corporation. In March 1999,
Moody's Investors Service confirmed the A3 ratings on Engelhard's senior
unsecured debt and confirmed the Company's commercial paper rating at Prime-2.
In addition, in March 1999 Standard & Poor's announced that ratings on Engelhard
remain on credit watch, with the implications being revised to "negative" from
"developing". If the

transaction is consummated as described above, Standard & Poor's indicated that
it would lower its corporate credit and senior unsecured debt ratings to
single-'A' minus from single-'A' and its commercial paper ratings to A-'2' from
A-'1'. These rating actions followed the March 2, 1999 announcement discussed
above.
