                                    --------

                                     PART I

Item 1.  Business:

(a)      Description of Business:

Harsco Corporation ("the Company") is a services and engineered products
company. The principal lines of business are: mill services that are provided to
steel and non-ferrous metal producers in over 30 countries, including the United
States; gas control and containment products for customers worldwide;
scaffolding services to the industrial maintenance and construction markets
principally in North America; railway maintenance of way services and equipment
that are provided to worldwide railroads; and several other lines of business
including, but not limited to, process equipment, industrial grating and bridge
decking, industrial pipe fittings, slag abrasives and roofing granules. The
Company's operations fall into three operating segments: Harsco Mill Services,
Harsco Gas and Fluid Control and Harsco Infrastructure. The Company has over 300
locations in 32 countries, including the United States.

In 1999, the Company acquired three businesses and divested three small non-core
operations.

Harsco Infrastructure Segment - In October 1999, the Company acquired Charter
plc's Pandrol Jackson railway track maintenance business. The transaction was
completed for approximately $48 million in cash plus assumption of liabilities,
for a total consideration of approximately $65 million. Pandrol Jackson
manufactures and markets worldwide a wide range of equipment and services used
in railway track maintenance. In December 1999, the Company completed the sale
of the railway switch, crossing and transit grinding business obtained as part
of the Pandrol Jackson railway maintenance acquisition. This business, with
annual sales of approximately $6 million, was divested in accordance with an
agreement with the Department of Justice as a condition to the acquisition of
Pandrol Jackson.

In July 1999, the Company acquired certain assets and assumed certain
liabilities of Structural Accessories, Inc. The total consideration was
approximately $2 million. Structural Accessories, Inc. manufactures and sells
bridge bearings and expansion joints.

Harsco Gas and Fluid Control Segment - In February 1999, the Company acquired
certain assets and assumed certain liabilities of Natural Gas Vehicle Systems,
Inc. Total consideration was approximately $3 million. Natural Gas Vehicle
Systems, Inc. manufactures cylinders used in vehicles which use natural gas. The
Company completed the sale of Astralloy Wear Technology in March 1999 and the
sale of the pavement marking and vegetation control business of Chemi-Trol in
August 1999.

Harsco Mill Services Segment - The Manchester truck dealership was sold in
September 1999.

The Company reports information about its operating segments according to the
"management approach". The management approach is based on the way management
organizes the segments within the enterprise for making operating decisions and
assessing performance. The Company's reportable segments are identified based
upon differences in products, services, and markets served.


                                      -2-
<PAGE>   3


The operations of the Company in any one country, except the United States, do
not account for more than 10% of sales. No single customer represented
10% or more of the Company's sales during 1999, 1998, and 1997. There are no
significant intersegment sales.

(b)      Financial Information about Industry Segments:

Financial information concerning Industry Segments is included in Note 14 to the
Consolidated Financial Statements under Item 8, "Financial Statements and
Supplementary Data".

(c)      Narrative Description of Business:

         (1)      A narrative description of the businesses by operating segment
                  is as follows:

Harsco Mill Services

This segment is the world leader in providing on-site highly specialized
services and technology under long-term contracts to steel producers and
non-ferrous metal industries. The Company's flame and recycling technologies
along with computerized scrap handling are several examples of the specialized
services the Company provides. These highly specialized services and
technologies include: scarfing, ferrocut, carbofer, briquetting and scrap
management. The Company provides in-plant transportation and other specialized
services, including slab management systems, general plant services, and other
recycling technology. Other services provided include metal reclamation; slag
processing, marketing and utilization; raw material management and handling;
by-product recovery and recycling; and finished product handling and transport.
Highly specialized recovery and cleaning equipment, installed and operated on
the property of steel producers, together with standard material handling
equipment are employed to reclaim metal and handle material. The customer uses
this reclaimed metal in its steel production process. The nonmetallic residual
slag is graded into various sizes at on-site Company-owned processing facilities
and then sold commercially. It is used as an aggregate material in asphalt
paving applications, railroad ballast and building blocks. Similar services are
also provided to non-ferrous metal industries, such as aluminum, copper, and
nickel.

This segment also provides roofing granules and slag abrasives. The Company's
slag abrasives and roofing granules are produced from utility coal slag and
natural rock materials at a number of locations throughout the United States.
The Company's Black Beauty(TM) abrasives are used for industrial surface
preparation, such as rust removal and cleaning of bridges, ship hulls, and
various structures. Roofing granules are sold to residential roofing shingle
manufacturers.

This segment operates at more than 160 sites in over 30 countries.  Also
included is the Reed Minerals unit, which provides roofing granules and
slag abrasives.

For 1999, percentage of consolidated net sales was 42%.

Harsco Gas and Fluid Control

Major product classes in this segment are gas containment and control equipment,
industrial pipe fittings, and process equipment, principally air-cooled heat
exchangers.

Gas containment products include cryogenic gas storage tanks, high pressure and
acetylene cylinders, propane tanks, and composite vessels for industrial and
commercial gases and other products. Gas control products include valves and
regulators serving a variety of markets, including the industrial gas commercial
refrigeration, life support, and outdoor recreation industries. Products are
used in applications such as scuba diving equipment and outdoor barbecue grills.



                                      -3-
<PAGE>   4

The segment provides custom designed and manufactured air-cooled heat
exchangers, principally for applications on field-sited natural gas compression
packages, for both domestic and international locations.

The segment is a major supplier of industrial pipe fittings and related products
for the plumbing, hardware and energy industries.

For 1999, percentage of consolidated net sales was 33%.

Harsco Infrastructure

Major product classes in this segment are scaffolding, shoring and concrete
forming services, railway maintenance-of-way services and equipment, and
industrial grating and bridge decking products.

The segment's scaffolding, shoring and concrete forming service products include
steel and aluminum support systems that are leased or sold to customers through
a North American network of some 50 branch service centers. The Company also
provides design engineering services, on-site installation, and equipment
management services.

The Company's railway maintenance-of-way services provide high technology
comprehensive track maintenance and new track construction support to railroad
customers. The railway maintenance-of-way services and equipment product class
includes specialized track maintenance equipment used by private and
government-owned railroads and urban transit systems worldwide. The equipment
manufactured by the Company includes a comprehensive range of specially-designed
systems used in the construction and maintenance of track and railbeds.

The segment manufactures a varied line of industrial grating products at several
plants in North America. The Company produces a full range of riveted,
pressure-locked and welded grating in steel, aluminum and fiberglass, used
mainly in industrial flooring, safety, and security applications for power,
paper, chemical, refining and processing applications.

The Company also produces bridge decking and related products for bridge
surfaces.

This segment also produces commercial and industrial boilers and hot water
heaters, and blenders, dryers and mixers for the chemical and food processing
industries.

For 1999, percentage of consolidated net sales was 25%.

   (1) (i)    The products and services of Harsco include a number of classes.
The product classes that contributed 10% or more as a percentage of
consolidated net sales in any of the last three fiscal years are as set forth in
the following table.

<TABLE>

                                               1999                    1998                    1997

   Gas Control and Containment Equipment       24%                     21%                     21%
</TABLE>

   (1) (ii)   New products and services are added from time to time; however, in
1999 none required the investment of a material amount of the Company's assets.

   (1) (iii)  The manufacturing requirements of the Company's operations are
such that no unusual sources of supply for raw materials are required. The raw
materials used by the Company include principally steel and to a lesser extent
aluminum which usually are readily available.

   (1) (iv)   While Harsco has a number of trademarks, patents and patent
applications, it does not consider that any material part of its business
is dependent upon them.



                                      -4-
<PAGE>   5


   (1) (v)    Harsco furnishes building products and materials and a wide
variety of specialized equipment for commercial, industrial, public works and
non-residential construction which are seasonal in nature. In 1999,
construction-related operations accounted for 12% of total sales.

   (1) (vi)   The practices of the Company relating to working capital items are
not unusual compared with those practices of other service providers or
manufacturers servicing mainly industrial and commercial markets.

   (1) (vii)  No material part of the business of the Company is dependent upon
a single customer or a few customers, the loss of any one of which would have a
material adverse effect upon the Company.

   (1) (viii) Backlog of orders was $231.6 million and $188.6 million as of
December 31, 1999 and 1998, respectively. It is expected that approximately 18%
of the total backlog at December 31, 1999, will not be filled during 2000. There
is no significant seasonal aspect to the Company's backlog. Backlog for
scaffolding, shoring and forming services, and for roofing granules and slag
abrasives is not included in the total backlog, because it is generally not
quantifiable due to the nature of the products and services provided. Contracts
for the Harsco Mill Services Segment are also excluded from the total backlog.
These Contracts have an estimated value of $3.6 billion at December 31, 1999.

   (1) (ix)   At December 31, 1999, the Company had no material contracts that
were subject to renegotiation of profits or termination at the election
of the Government.

   (1) (x)    The various businesses in which the Company operates are highly
competitive and the Company encounters active competition in all of its
activities from both larger and smaller companies who produce the same or
similar products or services or who produce different products appropriate for
the same uses.

   (1) (xi)   The expense for product development activities was $7,759,000,
$6,977,000, and $6,090,000 in 1999, 1998, and 1997, respectively.

   (1) (xii)  The Company has become subject, as have others, to increasingly
stringent air and water quality control legislation. In general, the Company has
not experienced substantial difficulty in complying with these environmental
regulations in the past and does not anticipate making any major capital
expenditures for environmental control facilities. While the Company expects
that environmental regulations may expand, and its expenditures for air and
water quality control will continue, it cannot predict the effect on its
business of such expanded regulations. For additional information regarding
environmental matters see Note 10 to the Consolidated Financial Statements
included in Item 8, "Financial Statements and Supplementary Data".

   (1) (xiii) As of December 31, 1999, the Company had approximately 15,700
employees.

         Domestic Operations and Export Sales:

during 1999 was due principally to a reduction in current liabilities of $44.3
million. Additionally, current assets increased, but at a lesser rate. The
largest reduction within current liabilities was an $18.0 million decrease in
notes payable and current maturities of long-term debt due principally to
refinancing short term notes into long-term debt. The reduction in current
liabilities also included $14.6 million of cash payments related to the
discontinued defense business. This is reflected as a reduction in Other current
liabilities in the Consolidated Balance Sheet.

A strategic focus of the Company is the minimization of capital employed
including inventory levels. Inventories decreased a net of $3.6 million despite
an increase of $16.3 million related to a fourth quarter 1999 acquired company
(acquisition). Receivables increased by $20.2 million principally due to the
acquisition and the timing of sales. Sales in the last two months of 1999
substantially exceeded those in the last two months of 1998.

Long-term debt increased in 1999 principally as a result of capital expenditures
(investments), share repurchases and an acquisition in the fourth quarter of
1999. Capital investments for 1999 were a record $175.2 million compared with
the previous record of $159.8 million in 1998. Investments were made for new
mill services contracts and other business growth initiatives, information
technology, new processes, and for productivity improvements. The Company
acquired 2,326,798 shares of its common stock in 1999 at a cost of $66.4
million. Due to the timing of actual cash settlements for the purchase of the
stock, the cash used in 1999 was $71.9 million. The capital investments, share
repurchases and cash dividends demonstrate the Company's continued commitment to
creating value through strategic investment and return of capital to
shareholders. In the past six years, the Company has committed over $1.7 billion
to increasing shareholder value.

</TABLE>

The Company's debt as a percent of total capital changed as a result of
increased debt and a decrease in equity capital due to the Company's share
repurchases and $27.3 million resulting from foreign currency translation
adjustments. The foreign currency translation adjustments are principally due to
1999's 14% decrease in the translated value of the euro and a 33% decrease in
the translated value of the Brazilian real.

</TABLE>

Lower returns on average equity, assets, and capital are due principally to
lower income in 1999 compared with the record income from continuing operations
for 1998. More specifically, income was lower in the first half of 1999 compared
to the first half of 1998. However, this was partially offset by higher income
for the second half of 1999 than the same period of 1998. Return on average
equity was positively affected by lower average equity due principally to share
repurchases. The Company's book value per share was unchanged at $16.22 per
share at December 31, 1998 and 1999.

NET CASH PROVIDED BY OPERATIONS:                $214.0           $189.3          $148.5
</TABLE>

Operating cash flows were a strong $214.0 million in 1999 compared with $189.3
million in 1998. These amounts include $14.6 million in 1999 and $13.6 million
in 1998 of cash payments for the discontinued defense business. The increase in
cash from operating activities was due principally to intensified efforts to
reduce inventories in 1999. A strategic management initiative in 1999 has
focused on a reduction of working capital components including inventory. This
focus will continue in 2000 and beyond. Lower earnings in 1999, the timing of
cash receipts from accounts receivable, and the timing of payments on accounts
payable, partially offset the significant improvement in cash provided by
operations.

The Company has a U.S. commercial paper borrowing program under which it can
issue up to $400 million of short-term notes in the U.S. commercial paper
market. In addition, the Company has a three billion Belgian franc commercial
paper program, equivalent to



                                      -13-
<PAGE>   14

approximately U.S. $75 million at December 31, 1999. The Belgian program
provides the capacity to borrow euros to fund the Company's European operations
more efficiently. The Company limits the aggregate commercial paper and
syndicated credit facility borrowings at any one time to a maximum $400 million.
At December 31, 1999, the Company had $205.4 million of U.S. commercial paper
debt outstanding, and $28.3 million of commercial paper debt outstanding under
the Belgian program.

The Company has available through a syndicate of banks a $400 million
multi-currency five-year revolving credit facility, extending through July 2001.
This facility serves as back-up to the Company's U.S. commercial paper program.
As of December 31, 1999 there were no borrowings outstanding under this
facility.

The Company's outstanding long-term notes are rated A by Standard & Poor's, A by
Fitch IBCA and A-3 by Moody's. The Company's commercial paper is rated A-1 by
Standard & Poor's, F-1 by Fitch IBCA and P-2 by Moody's. A Form S-3 shelf
registration is on file with the Securities and Exchange Commission for the
possible issuance of up to an additional $200 million of new debt securities,
preferred stock or common stock.

As supported by the above, the Company's financial position and debt capacity
should enable it to meet its current and future requirements. As additional
resources are needed, the Company should be able to obtain funds readily and at
competitive costs. The Company is positioned to continue to invest in strategic
acquisitions, selective high return capital investments, and to issue cash
dividends as means to enhance shareholder value. The Company recently completed
its strategic initiative of purchasing 20% of the Company's outstanding shares.
With the completion of this program, the Company intends to use future
discretionary cash flow principally for debt reduction and acquisitions,
although additional shares may be acquired from time to time.

SUMMARY ANALYSIS OF RESULTS

Despite improving conditions in the steel industry during the last six months of
1999, the Company's results for the full year of 1999 reflect the adverse
effects of a steel industry affected by overcapacity, reduced prices and weak
demand in certain parts of the world. These problems contributed to reduced
steel production and financial stress at several steel mills. Certain customers
in the United States were forced to file for bankruptcy protection. In the
second half of 1999, increased levels of domestic steel production and capacity
utilization



                                      -14-
<PAGE>   15

favorably affected the Company's results. Second half net income and earnings
per share for 1999 exceeded the same period of 1998.

Soft market conditions in the industrial gas and oil industries contributed to
lower results for 1999. However, the significant increase in crude oil prices
that was experienced in late 1999 contributed to improved results for the second
half. The Company's order backlog in the Harsco Gas and Fluid Control Segment as
of December 31, 1999 is 27% higher than as of December 31, 1998, reflecting
improved business conditions.

In 1999, the strong U.S. dollar adversely impacted the foreign currency
translation effect on results of operations in many countries in which the
Company operates.

Additionally, pre-tax pension expense for 1999, calculated in accordance with
SFAS No. 87, was $10.6 million higher than 1998. The increase unfavorably
impacted cost of services and products sold as well as selling, general, and
administrative expenses.

Despite decreases in the Company's revenues and income for 1999 when compared to
1998, certain economic and market conditions as of December 31, 1999,
particularly for the Harsco Mill Services and the Harsco Gas and Fluid Control
Segments, indicate that the unfavorable trends experienced in 1999 have begun to
dissipate.

COMPARATIVE ANALYSIS OF CONSOLIDATED RESULTS

REVENUES

Revenues for 1999 were $1.72 billion, slightly below 1998. The decrease reflects
principally the unfavorable effects of market conditions in the steel, oil and
gas industries during the first six months of 1999. Improvements in market
conditions in the second half of 1999, as well as higher sales from
acquisitions, net of dispositions of non-core businesses, partially offset the
lower sales reported in the first six months of 1999. Excluding the adverse
foreign exchange translation effect of the strengthening U.S. dollar,
particularly relative to the Brazilian real, the euro, the South African rand
and the British pound, revenues exceeded 1998.

COST OF SALES AND SELLING, GENERAL, AND ADMINISTRATIVE EXPENSES

Costs of services and products sold for 1999 approximated that of 1998. As a
result of divesting certain non-core businesses and the Company's continuing
cost reduction, process improvement, and reorganization efforts, selling,
general, and administrative expenses decreased despite the inclusion of acquired
companies. The total of cost of sales plus selling, general, and administrative
expenses was lower than 1998, despite a significant increase in pension expense.

NET SPECIAL CHARGES AND GAINS

In 1999 the Company incurred $6.0 million of net pre-tax expense related to
special charges and gains. Special charges include asset write-downs, employee
termination benefit costs, costs to exit activities, and other
reorganization-related costs resulting from the company's continuing efforts to
consolidate and streamline its businesses. Gains result principally from the
disposal of non-core businesses. In 1998 net special charges were $2.2 million.

Net gains for 1998 of $29.1 million consist principally of a pre-tax net gain of
$27 million recorded on the October 1998 sale of the Nutter Engineering unit of
the Harsco Gas and Fluid Control Segment. Such gains are reflected as
adjustments to reconcile net income to net cash provided by operating activities
in the Consolidated Statement of Cash Flows. Total proceeds associated with 1998
special gains were $42.9 million and are included in proceeds from the sale of
businesses and property, plant and equipment in the investing activities section
of the Consolidated Statement of Cash Flows. Net gains for 1999 were $0.6
million.

Impaired asset write-downs for 1999 of $2.9 million include a $1.9 million
pre-tax, non-cash, write-down of the Company's investment in Bio-Oxidation
Services Inc. which is included in the Harsco Gas and Fluid Control Segment. The
Company's investment in Bio-Oxidation Services Inc. is being held for disposal.
The write-down amount was measured on the basis of the lower of carrying amount
or fair value less cost to sell. Fair value was determined using available
information based upon the estimated amount at which the assets could be sold in
a current transaction between willing parties. For the year ended December 31,
1999, Bio-Oxidation Services Inc. recorded a pre-tax loss of $2.3 million which
includes the asset write-down of $1.9 million. The Company estimates that the
disposal will occur during 2000.

Impaired asset write-downs of $14.4 million for 1998 include a $6.1 million
pre-tax, non-cash, write-down of the Company's investment in Bio-Oxidation
Services Inc. For the year ended December 31, 1998, Bio-Oxidation Services Inc.
recorded a pre-tax loss of $9.8 million which includes the asset write-down of
$6.1 million.

Impaired asset write-downs for 1998 also include a $6.1 million pre-tax,
non-cash, write-down of assets, principally property, plant and equipment in the
Harsco Mill Services Segment. The



                                      -16-
<PAGE>   17

write-down became necessary as a result of significant adverse changes in the
international economic environment and the steel industry. Impairment loss was
measured as the amount by which the carrying amount of assets exceeded their
estimated fair value. Fair value was estimated based upon the expected future
realizable net cash flows. In September 1999, assets associated with a
substantial portion of this provision were sold in conjunction with the
termination settlement of a contract in Russia.

Employee termination benefit costs consist principally of severance arrangements
to employees terminated as a result of management reorganization actions. Under
these reorganization actions, the Company's management has established and
approved specific plans of termination. Details of the termination benefit plans
have been communicated to the affected employees prior to recognition of related
provisions. Non-cash charges for employee termination benefit costs are included
as adjustments to reconcile net income to net cash provided by operating
activities in the Consolidated Statement of Cash Flows.

During 1999, $2.9 million of expense related to employee termination benefits
was incurred principally in the Harsco Mill Services Segment, primarily in
France and the United Kingdom. In 1999, 220 employees were included in employee
termination arrangements initiated by the Company and approximately $1.8 million
of cash payments were made under such arrangements. The payments are reflected
as uses of operating cash in the Consolidated Statement of Cash Flows.

During 1998, $6.5 million of expense related to employee termination benefits
occurred principally in the Harsco Mill Services Segment, primarily in South
Africa, United States, France, and Germany. In 1998, approximately 670 employees
were included in employee termination arrangements initiated by the Company and
approximately $2.4 million of cash payments were made under such arrangements.
An additional $3.3 million was disbursed in 1999 for the 1998 reorganization
actions.

INTEREST EXPENSE

The Company's defense business was sold in the fourth quarter of 1997. This
resulted in $344 million of pre-tax cash proceeds. The availability of a
substantial portion of this cash in 1998 resulted in additional interest income,
as well as reduced interest expense compared to 1999. Additionally, interest
expense for 1999 was higher than 1998 as a result of increased borrowings for
record capital expenditures (investments), the Company's share repurchase
program and an acquisition in the fourth quarter of 1999. Capital investments,
$175.2 million in 1999, were made for new mill services contracts, other
business growth initiatives, information technology, new processes, and for
productivity improvements.

INCOME BEFORE INCOME TAXES AND MINORITY INTEREST

As a result of factors disclosed in previous sections, income before income
taxes and minority interest was down 18% from 1998.

PROVISION FOR INCOME TAXES

The effective income tax rate for 1999 was 35% versus 37.5% for 1998. The
reduction in the income tax rate is due principally to lower effective income
tax rates on domestic earnings.

NET INCOME AND EARNINGS PER SHARE

Net income of $90.7 million was below 1998. Basic earnings per common share were
$2.22 down from $2.36 in 1998. Diluted earnings per common share were $2.21 down
from $2.34 in 1998.

</TABLE>

Sales of the Harsco Mill Services Segment were below 1998. The inclusion of
sales from an acquired company for the full year 1999 was partially offset by
the 1998 disposition of a non-core business. The decrease also reflects the
unfavorable effects of foreign exchange translation and overcapacity in the
steel industry which adversely affected worldwide steel prices and production.
This is particularly true in the United States where the steel industry filed
complaints with the government due to alleged unfairly low-priced imports. Lower
steel production adversely affected volume and margins at most steel mills in
the United States including many of the Company's customers. However, during the
last six months of 1999, steel production and capacity utilization in the United
States trended upwards reflecting the highest levels since the second quarter of
1998. Additionally, certain other key countries in which the Company conducts
business also experienced upward trends in steel production in 1999. The Harsco
Mill Services Segment fourth quarter 1999 results reflected this trend as
revenues and income, excluding special charges and gains, exceeded the same
period of 1998.

Income before interest, income taxes, and minority interest of the Harsco Mill
Services Segment was below 1998. Results in 1998 included $10.0 million of
pre-tax, non-cash write-downs of assets, principally property, plant and
equipment. Additionally, $4.9 million of employee termination benefit costs were
included in net special charges and gains in 1998. Excluding net special charges
and gains, income before interest, income taxes, and minority interest was $84.5
million in 1999 compared to $99.9 million in 1998.

The decrease in income for 1999 reflected the adverse effects of lower steel
production and prices in the first half of 1999. Results for 1999 include a
foreign currency transaction gain in Brazil, while in 1998, net foreign currency
translation exchange losses were incurred. The transaction gain in Brazil
partially offset the net unfavorable foreign currency impact associated with
translation of the results of operations of the Harsco Mill Services Segment.

      Segment. Sales of these product lines were $26.9 million and $29.2 million
      for the years 1999 and 1998, respectively.

Sales of the Harsco Gas and Fluid Control Segment decreased from 1998. The
inclusion of a full year's sales of three acquired companies was more than
offset by lower sales of process equipment due in part to the disposition of
three non-core businesses. Reduced sales of gas control and containment
equipment and process equipment also reflected decreased demand in the
industrial gas and oil industries. In late 1999, these industries were favorably
affected by rising crude oil prices.

Income before interest, income taxes, and minority interest of the Harsco Gas
and Fluid Control Segment was below 1998 principally due to the inclusion in
1998 of gains on the disposal of two businesses. Excluding net special charges
and gains, income before interest, income taxes, and minority interest was $50.0
million in 1999 compared to $54.1 million in 1998. The decrease reflected the
adverse effects of reduced demand from customers in the industrial gas and oil
industries.

Segment net income was below 1998 principally due to the inclusion in 1998 of
gains on the disposal of two businesses. Net income for 1999 was adversely
affected, but to a lesser extent than 1998, by valuation provisions related to
the write-down of assets held for disposal. Excluding net special charges and
gains, net income in 1999 was $28.6 million compared to $30.0 million in 1998.

      of the heat transfer and industrial blending equipment product lines from
      the Harsco Gas and Fluid Control Segment to the Harsco Infrastructure
      Segment. Sales of these product lines were $26.9 million and $29.2 million
      for the years 1999 and 1998, respectively.

The Harsco Infrastructure Segment's sales for 1999 exceeded 1998 due to
increased sales of scaffolding, shoring and forming services, as well as sales
of railway maintenance-of-way equipment and contract services which included the
effect of an acquisition in the fourth quarter of 1999.

Income before interest, income taxes, and minority interest of the Harsco
Infrastructure Segment was significantly above 1998. Excluding net special
charges and gains, income before interest, income taxes, and minority interest
was $41.2 million compared to $37.7 million in 1998. The increase was due
principally to improved margins on sales of grating products and, to a lesser
extent, higher income for scaffolding, shoring and forming services.

Segment net income was above 1998 due principally to improved margins on sales
of grating products. Additionally, increased income was recorded for
scaffolding, shoring and forming services. Excluding net special charges and

</TABLE>

SUMMARY ANALYSIS OF RESULTS

The Company's results for 1998 showed substantial improvement over 1997. The
acquisition of Faber Prest Plc for the Harsco Mill Services Segment and three
acquisitions for the Harsco Gas and Fluid Control Segment enhanced the market
leading position of these segments, and contributed to the overall revenue
growth. Strong results from scaffolding, shoring and forming services and
process equipment also contributed to improved operating results.

However, 1998 results were adversely affected by the Asian economic crisis,
particularly its effects on the steel industry. Beginning in the third quarter
of 1998, a significant decline in worldwide steel prices occurred due to
overcapacity in the industry. Several mills temporarily idled capacity,
impacting activity levels for the Harsco Mill Services Segment. The Asian
economic crisis also impacted the results of the Harsco Gas and Fluid Control
Segment's Asian operations, lowered export sales from certain domestic
locations, and reduced margins of certain domestic operations adversely affected
by low-priced imports.

The strong U.S. dollar also adversely impacted 1998 results compared to 1997 for
many of the company's international operations.

COMPARATIVE ANALYSIS OF CONSOLIDATED RESULTS

REVENUES

Revenues from continuing operations for 1998 were $1.74 billion, 7% above 1997.
The increase was due to the inclusion of acquired companies in 1998. Inclusion
of the acquired companies increased revenues for the Harsco Mill Services
Segment and for gas control and containment equipment in the Harsco Gas and
Fluid Control Segment. Process equipment sales also increased. Sales of
scaffolding, shoring, and forming services increased, but to a lesser extent.
These increases were partially offset by lower sales of industrial fittings,
railway maintenance-of-way equipment and contract services, and grating.
Excluding the adverse foreign exchange translation effect of the strengthening
U.S. dollar, revenues from continuing operations for 1998 were approximately 8%
above 1997.

<PAGE>   24

COST OF SALES AND SELLING, GENERAL, AND ADMINISTRATIVE EXPENSES

Cost of products and services sold increased due to the inclusion of acquired
companies. Selling, general, and administrative expenses were only slightly
above 1997, despite the inclusion of acquired companies. This resulted from the
Company's cost control efforts. Also included in 1998 were $1.7 million of net
pre-tax foreign currency translation/transaction losses, principally due to the
weakening of the Mexican new peso and the Russian ruble in relation to the U.S.
dollar, as compared with $0.5 million of net foreign currency
translation/transaction gains in 1997.

NET SPECIAL CHARGES AND GAINS

In 1998 the Company incurred $2.2 million of net pre-tax special charges
including asset write-downs, employee termination benefit costs, costs to exit
activities, and other reorganization-related costs, compared with $2.6 million
in 1997. The charges were incurred as a result of the Company's continuing
efforts to consolidate and streamline its businesses. The $2.2 million net
special charges for 1998 include a $15.6 million net charge in the Harsco Mill
Services Segment and a $4.8 million net charge in the Harsco Infrastructure
Segment partially offset by an $18.2 million net gain in the Harsco Gas and
Fluid Control Segment. This net gain included a $27 million gain associated with
the sale of a business. The $2.6 million net special charges for 1997 include a
$1.8 million net charge in the Harsco Gas and Fluid Control Segment, a $0.4
million net charge in the Harsco Mill Services Segment and a $0.7 million net
charge in general Corporate expenses, partially offset by a $0.3 million net
gain in the Harsco Infrastructure Segment.

Net gains for 1998 consist principally of a pre-tax net gain of $27 million
recorded on the October 1998 sale of the Nutter Engineering unit of the Harsco
Gas and Fluid Control Segment. Such gains are reflected as adjustments to
reconcile net income to net cash provided by operating activities in the
Consolidated Statement of Cash Flows. Total proceeds associated with special
gains were $42.9 million and are included in proceeds from the sale of
businesses and property, plant and equipment in the investing activities section
of the Consolidated Statement of Cash Flows.

Impaired asset write-downs for 1998 include a $6.1 million pre-tax, non-cash,
write-down of the Company's investment in Bio-Oxidation Services Inc. which is
included in the Harsco Gas and Fluid Control Segment. The write-down amount was
measured on the basis of the lower of carrying amount or fair value less cost to
sell. Fair value was determined using available information based upon the
estimated amount at which the assets could be sold in a current transaction
between willing parties. For the year ended December 31, 1998 Bio-Oxidation
Services Inc. recorded a pre-tax loss of $9.8 million, which includes the asset
write-down of $6.1 million.

Impaired asset write-downs also include a fourth quarter 1998 $6.1 million
pre-tax, non-cash, write-down of assets, principally property, plant and
equipment, in the Harsco Mill Services Segment. The write-down became necessary
as a result of significant adverse changes in the international economic
environment and the steel industry. Impairment loss was measured as the amount
by which the carrying amount of assets exceeded their estimated fair value. Fair
value was estimated based upon the expected future realizable net cash flows.

Non-cash impaired asset write-downs are generally included in Other (income) and
expenses in the Consolidated Statement of Cash Flows as adjustments to reconcile
net income to net cash provided by operating activities.

Employee termination benefit costs consist principally of severance arrangements
to employees terminated as a result of management reorganization actions. Under
these reorganization actions, the Company's management has established and
approved specific plans of termination. Details of the termination benefit plans
have been communicated to the affected employees prior to recognition of related
provisions. Non-cash charges for employee termination benefit costs are included
as adjustments to reconcile net income to net cash provided by operating
activities in the Consolidated Statement of Cash Flows.

During 1998, $6.5 million of reorganization expense related to employee
termination benefits occurred principally in the Harsco Mill Services Segment,
primarily in South Africa, United States, France, and Germany. In 1998,
approximately 670 employees were included in employee termination arrangements
initiated by the Company and approximately $2.4 million of cash payments were
made under such arrangements. An additional $3.3 million was disbursed in 1999
for the 1998 reorganization actions.

Costs to exit activities consist of incremental direct costs of reorganization
actions and lease run-out costs. Such costs are recorded when a specific exit
plan is approved by management. Relocation expenses, such as employee moving
costs, are classified as exit costs and are expensed as incurred. Other costs
classified in this category are generally expensed as incurred. During 1998,
$1.0 million and $0.8 million of exit costs, principally relocation expenses,
were included in the Harsco Mill Services and Harsco Infrastructure Segments,
respectively. During 1997, $1.5 million of exit costs were included in the
Harsco Mill Services Segment. These costs resulted principally from the
expiration or termination of contracts at certain mill sites, as well as
facility relocation costs.

INTEREST EXPENSE

Interest expense increased in 1998 as a result of increased borrowings for the
Company's share repurchase program and for the funding of acquisitions.

INCOME FROM CONTINUING OPERATIONS BEFORE INCOME TAXES AND MINORITY INTEREST

Income from continuing operations before income taxes and minority interest
increased 5% from 1997 due principally to improved performance. Increased
earnings were achieved due principally to improved results for scaffolding,
shoring, and forming services and process equipment, as well as the inclusion of
acquired companies. These increases were partially offset by lower results for
metal reclamation and mill services, industrial fittings, grating, and gas
control and containment equipment, as well as start-up losses and asset
write-downs associated with the medical waste disposal services business.

PROVISION FOR INCOME TAXES

The effective income tax rate for continuing operations for 1998 was 37.5%
versus 38% in 1997. The reduction in the income tax rate is due to lower
effective income tax rates on state, as well as international earnings.

INCOME FROM CONTINUING OPERATIONS

Income from continuing operations was up 7% from 1997. Basic earnings per common
share from continuing operations of $2.36 were up 15% from 1997.

NET INCOME AND EARNINGS PER SHARE

Net income of $107.5 million for 1998 was below 1997, which included $178.4
million of income and a gain from the Company's discontinued defense business.
Basic earnings per common share were $2.36, down from $5.72 in 1997. Diluted
earnings per common share were $2.34, down from $5.67 in 1997.

Sales of the Harsco Mill Services Segment were above 1997 despite the adverse
effect of foreign exchange translation. The increase was due to the inclusion of
an acquired company as of the second quarter of 1998.

Income before interest, income taxes, and minority interest of the Harsco Mill
Services Segment was below 1997. Excluding special charges and gains, income
before interest, income taxes, and minority interest for 1998 was $99.9 million,
a slight increase from $99.5 million for 1997. Increased income due to the
inclusion of an acquired company was offset by the adverse foreign exchange
translation effect of the strong U.S. dollar.

Net income of the Harsco Mill Services Segment was below 1997. The decrease
included after-tax net special charges of $9.8 million in 1998, as well as the
adverse foreign exchange translation effect of the strong U.S. dollar, offset by
the inclusion of an acquired company. The special charges included principally
asset write-downs and employee termination benefit costs.

      and $28.2 million for the years 1998 and 1997, respectively.

Sales of the Harsco Gas and Fluid Control Segment increased from 1997 due to the
inclusion of sales of three acquired companies and due to increased sales for
process equipment.

Income before interest, income taxes, and minority interest of the Harsco Gas
and Fluid Control Segment was significantly above 1997's comparable amount due
to the inclusion of special charges and gains, including a $27 million pre-tax
net gain from the sale of a business. Excluding all special charges and gains,
income before interest, income taxes, and minority interest was $54.1 million in
1998 compared to $53.1 million in 1997. This increase was due to improved
results for process equipment.

</TABLE>

Industrial services income decreased 19% in 1998 compared to 1997 due to net
special charges and gains. Net special charges and gains in 1998 included asset
write-downs associated with the medical waste disposal services business and
asset write-downs and employee termination benefit costs in the Harsco Mill
Services Segment. Excluding net special charges and gains, industrial services
income was $102.5 million in 1998 compared to $98.9 million in 1997. This
increase was due to improved results for scaffolding, shoring, and forming
services.

Engineered products income increased 35% in 1998 compared to 1997. This increase
was principally due to a $27 million pre-tax net gain from the sale of a
business. Excluding net special charges and gains, engineered products income in
1998 was $89.2 million compared to $83.1 million in 1997. This increase was due
to improved results for process equipment and the inclusion of acquired
companies.

ECONOMIC ENVIRONMENT

The Company has currency exposures for its international operations which may be
subject to volatility, such as the 1999 foreign exchange fluctuations
experienced in Brazil and the decline of the euro. Such exposures may result in
reduced sales, income, and cash flows. The situations in Brazil and Europe are
not expected to have a material adverse impact on the Company's financial
position or results of operations. However, these and similar risks could result
in a material impact on the Company's financial position or results of
operations in the future. Balance sheet translation adjustments for the
Brazilian and European operations generally do not affect results of operations.

In 1998 and early 1999 the worldwide steel industry experienced selling price
reductions and production curtailments at many steel producers, particularly in
the United States. The United States steel industry was unfavorably affected by
imports of low-priced foreign steel. Additionally, certain steel producers were
forced to file for bankruptcy protection. The situation improved in



                                      -29-
<PAGE>   30

the second half of 1999. There is a risk that the Company's future results of
operations or financial condition could be adversely affected if the steel
industry's problems were to continue. The Harsco Mill Services Segment provides
services at steel mills throughout the world. The future financial impact on the
Company associated with these risks cannot be estimated.

RESEARCH AND DEVELOPMENT

The Company invested $7.8 million in internal research and development programs
in 1999, an increase of 11% above 1998. Internal funding for the Harsco
Infrastructure Segment amounted to $3.5 million, principally for railway
maintenance-of-way equipment and services. Expenditures for the Harsco Mill
Services and Harsco Gas and Fluid Control Segments were $3.2 million and $1.1
million, respectively.

BACKLOG

As of December 31, 1999, the Company's order backlog, exclusive of long-term
mill services contracts, was $231.6 million compared to $188.6 million as of
December 31, 1998, a 23% increase. The Harsco Infrastructure Segment order
backlog at December 31, 1999 was $151.6 million, an increase of 24% over the
December 31, 1998 backlog of $122.5 million. This increase principally results
from the fourth quarter 1999 Pandrol Jackson acquisition. The Harsco Gas and
Fluid Control Segment backlog increased approximately 27% to $80.0 million from
$62.8 million as of December 31, 1998. The increase results from higher backlog
for gas control and containment equipment. Backlog for scaffolding, shoring and
forming services of the Harsco Infrastructure Segment and roofing granules and
slag abrasives of the Harsco Mill Services Segment are excluded from the backlog
amounts. They are generally not quantifiable due to the nature of the products
and services provided.

Metal reclamation and mill services contracts have an estimated value of $3.6
billion at December 31, 1999, an increase of approximately 9% over the December
31, 1998 amount of $3.3 billion.

DIVIDEND ACTION

The Company paid four quarterly cash dividends of $.225 per share in 1999, for
an annual rate of $.90. This is an increase of 2.3% from 1998. At the November
1999 meeting, the Board of Directors increased the dividend 4.4% to an annual
rate of $.94 per share. The Board normally reviews the dividend rate
periodically during the year and annually at its November meeting. There are no
material restrictions on the payment of dividends.

The Company is proud of its history of paying dividends. The Company has paid
dividends each year since 1939. The February 2000 payment marked the 199th
consecutive quarterly dividend paid at the same or at an increased rate. During
the five-year period ended December 31, 1999, dividends paid were increased five
times. In 1999, the dividend payout rate was 41%. The Company is philosophically
committed to maintaining or increasing the dividend at a sustainable level.

YEAR 2000 READINESS

The Company has taken steps to assure that its operations are not adversely
impacted by potential Year 2000 computer failures. All phases of the Company's
Year 2000 readiness process have been completed for information technology and
non-information technology systems. Those phases included awareness, assessment,
prioritization, remediation or replacement, testing and contingency planning.
Additionally, Year 2000 readiness assessments have been completed of critical
third parties including significant business



                                      -30-
<PAGE>   31

partners, suppliers, and major customers. As of December 31, 1999, no mission
critical third parties have indicated that they are not Year 2000 ready.

Through March 16, 2000 the Company has not experienced any material Year 2000
failures.

As of December 31, 1999, the Company has incurred approximately $3.3 million in
cumulative Year 2000 readiness costs. The Company does not expect to incur
additional Year 2000 readiness costs unless a material Year 2000 failure occurs.

The Company believes that its major Year 2000 risks involve the continuing Year
2000 readiness and performance of third parties. The impact of such Year 2000
risks and potential failures on the Company's financial position or results of
operations cannot be estimated.

The Company has developed contingency plans to be invoked in the event of a
material Year 2000 failure. However, if there is an extended Year 2000 failure
by several third parties or of supporting infrastructures, there could be a
material adverse impact on the Company's financial position or results of
operations.

Year 2000 Statements contained herein about Harsco products and services are
Year 2000 Readiness Disclosures, pursuant to the Year 2000 Information and
Readiness Disclosure Act, 15 U. S. C. 1-note.

FORWARD LOOKING STATEMENTS

The nature of the Company's operations and the many countries in which it
operates subject it to changing economic, competitive, regulatory, and
technological conditions, risks, and uncertainties. In accordance with the "safe
harbor" provisions of the Private Securities Litigation Reform Act of 1995, the
Company provides the following cautionary remarks regarding important factors
which, among others, could cause future results to differ materially from the
forward-looking statements, expectations, and assumptions expressed or implied
herein. These include statements about our management confidence and strategies
for performance; expectations for new and existing products, technologies, and
opportunities; and expectations for market segment and industry growth and
earnings.

These factors include, but are not limited to: (1) changes in the worldwide
business environment in which the Company operates, including import, licensing,
and trade restrictions, currency exchange rates, interest rates, and capital
costs; (2) changes in governmental laws and regulations, including taxes; (3)
market and competitive changes, including market demand and acceptance for new
products, services, and technologies; (4) effects of unstable governments and
business conditions in emerging economies; and (5) other risk factors listed
from time to time in the Company's SEC reports. The Company does not intend to
update this information and disclaims any legal liability to the contrary.

Item 7A.  Quantitative And Qualitative Disclosures About Market Risk

The Company is exposed to foreign currency risk in its international operations.
The Company conducts business in over thirty foreign countries and approximately
36%, 37% and 36% of the Company's net revenues for the years ended December 31,
1999, 1998 and 1997, respectively, were derived from the Company's operations
outside the United States. To illustrate the effect of foreign currency exchange
rate changes due to the strengthening of the U.S. dollar, in 1999 sales would
have been 2.5% greater using the average exchange rates for the year 1998. A
similar comparison for the year 1998, would have increased sales one percent, if
the average exchange rates for 1997 would have remained the same in 1998.

The Company seeks to reduce exposures to foreign currency fluctuations, through
the use of forward exchange contracts. At December 31, 1999, these contracts
amounted to $19.2 million and all mature within 2000. The Company does not hold
or issue financial instruments for trading purposes, and it is the Company's
policy to prohibit the use of derivatives for speculative purposes.

Also, the Company's cash flows and earnings are subject to changes in interest
rates. Total debt of $455.1 million as of December 31, 1999 had interest rates
ranging from 3.2% to 13.0%, of which approximately 35% were at fixed rates of
interest. The weighted average interest rate of total debt was approximately
5.8%. At current debt levels, a one percentage increase in interest rates would
increase interest expense by approximately three million dollars per year.

For additional information, see Note 13, Financial Instruments, to the
Consolidated Financial Statements under Item 8, "Financial Statements and
Supplementary Data."

The Company is also exposed to risks related to changing economic conditions and
their effect on the markets it serves and on the Company's supply chain, and
related costs. For additional information, see "Economic Environment" under Item
7, "Management's Discussion and Analysis of Financial Condition and Results of
Operations."

                                                  OF INDEPENDENT ACCOUNTANTS

To the Shareholders of Harsco Corporation:

In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of income, of shareholders' equity, of comprehensive
income and of cash flows present fairly, in all material respects, the financial
position of Harsco Corporation and Subsidiary Companies at December 31, 1999 and
1998, and the results of their operations and their cash flows for each of the
three years in the period ended December 31, 1999, in conformity with accounting
principles generally accepted in the United States. 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 auditing standards
generally accepted in the United States, which require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

HARSCO CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

CONSOLIDATION

The consolidated financial statements include the accounts of Harsco Corporation
and its majority-owned subsidiaries ("Company"). Investments in unconsolidated
entities (all of which are 20-50% owned) are accounted for under the equity
method.

CASH AND CASH EQUIVALENTS

Cash and cash equivalents include cash on hand, demand deposits, and short-term
investments which are highly liquid in nature and have an original maturity of
three months or less.

INVENTORIES

Inventories are stated at the lower of cost or market. Inventories in the United
States are accounted for using principally the last-in, first-out (LIFO) method.
Other inventories are accounted for using the first-in, first-out (FIFO) or
average cost methods.

DEPRECIATION

Property, plant and equipment is recorded at cost and depreciated over the
estimated useful lives of the assets using principally the straight-line method.
When property is retired from service, generally the cost of the retirement is
charged to the allowance for depreciation to the extent of the accumulated
depreciation, and the balance is charged to income. Long-lived assets to be
disposed are not depreciated while they are held for disposal.

INTANGIBLE ASSETS

Intangible assets consist principally of cost in excess of net assets of
businesses acquired, which is amortized on a straight line basis over a period
not to exceed 30 years. Accumulated amortization was $74.9 and $58.6 million at
December 31, 1999 and 1998, respectively.

IMPAIRMENT OF LONG-LIVED ASSETS

Long-lived assets, including cost in excess of net assets of businesses acquired
and other intangible assets, used in the Company's operations are reviewed for
impairment when events and circumstances indicate that the carrying amount of an
asset may not be recoverable. The Company's policy is to record an impairment
loss when it is determined that the carrying amount of the asset exceeds the sum
of the expected undiscounted future cash flows resulting from use of the asset
and its eventual disposition. Impairment losses are measured as the amount by
which the carrying amount of the asset exceeds its fair value. Long-lived assets
to be disposed are reported at the lower of the carrying amount or fair value
less cost to sell.

REVENUE RECOGNITION

Revenue is recognized for product sales generally when title and risk of loss
transfer. Service sales are recognized over the contractual period or as
services are performed.

INCOME TAXES

United States federal and state income taxes and non-U.S. income taxes are
provided currently on the undistributed earnings of international subsidiaries
and unconsolidated affiliated entities, giving recognition to current tax rates
and applicable foreign tax credits, except when management has specific plans
for reinvestment of undistributed earnings which will result in the indefinite
postponement of their remittance. Deferred taxes are provided using the asset
and liability method for temporary differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases.

ACCRUED INSURANCE AND LOSS RESERVES

The Company retains a significant portion of the risk for workers' compensation,
automobile, general, and product liability losses. Reserves have been recorded
which reflect the undiscounted estimated liabilities including claims incurred
but not reported. Changes in the estimates of the reserves are included in net
income in the period determined. Amounts estimated to be paid within one year
have been classified as Other current liabilities, with the remainder included
in Insurance liabilities.

FOREIGN CURRENCY TRANSLATION

The financial statements of the Company's subsidiaries outside the United
States, except for those subsidiaries located in highly inflationary economies,
are principally measured using the local currency as the functional currency.
Assets and liabilities of these subsidiaries are translated at the exchange
rates as of the balance sheet date. Resulting translation adjustments are
recorded in the cumulative translation adjustment, a separate component of Other
comprehensive income (expense). Income and expense items are translated at
average monthly exchange rates. Gains and losses from foreign currency
transactions are included in net income. For subsidiaries operating in highly
inflationary economies, gains and losses on foreign currency transactions and
balance sheet translation adjustments are included in net income.

Effective January 1997, the Company's operations in Mexico were accounted for as
a highly inflationary economy since the three-year cumulative rate of inflation
at December 31, 1996 exceeded 100%. The functional currency for the Company's
operations in Mexico was the U.S. dollar for 1997 and 1998. Effective January
1999, the three-year cumulative rate of inflation fell below 100%. As of January
1, 1999, the Company measures the financial statements of its Mexican entities
using the Mexican new peso as the functional currency.

Effective January 1998, the Company's operations in Brazil were no longer
accounted for as a highly inflationary economy, because the three-year
cumulative rate of inflation fell below 100%. The Company measures the financial
statements of its Brazilian entities using the Brazilian real as the functional
currency.

FINANCIAL INSTRUMENTS AND HEDGING

The Company has subsidiaries principally operating in North America, South
America, Europe, and Asia-Pacific. These operations are exposed to fluctuations
in related foreign currencies in the normal course of business. The Company
seeks to reduce exposure to foreign currency fluctuations, through the use of
forward exchange contracts. The Company does not hold or issue financial
instruments for trading purposes, and it is the Company's policy to prohibit the
use of derivatives for speculative purposes. The Company has a Foreign Currency
Risk Management Committee that meets periodically to monitor foreign currency
risks.

The Company executes forward foreign exchange contracts to hedge transactions of
its non-U.S. subsidiaries for firm purchase commitments and for export sales
denominated in foreign currencies. These contracts generally are for 90 to 180
days or less. For those contracts that hedge an identifiable transaction, gains
or losses are deferred and accounted for as part of the underlying transaction.
The cash flows from these contracts are classified consistent with the cash
flows from the transaction being hedged. The Company also enters into forward
foreign exchange contracts for intercompany foreign currency commitments. These
foreign exchange contracts do not qualify as hedges. Therefore, gains and losses
are recognized in income based on fair market value.

OPTIONS FOR COMMON STOCK

The Company uses the intrinsic value based method to account for options granted
for the purchase of common stock. No compensation expense is recognized on the
grant date, since at that date, the option price equals the market price of the
underlying common stock. The Company discloses the pro-forma effect of
accounting for stock options under the fair value method.

EARNINGS PER SHARE

Basic earnings per share is calculated using the average shares of common stock
outstanding, while diluted earnings per share reflects the potential dilution
that could occur if stock options were exercised.

USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS

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, the 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.

RECLASSIFICATIONS

Certain reclassifications have been made to prior years' amounts to conform with
current year classifications.

NEW FINANCIAL ACCOUNTING STANDARDS NOT YET ADOPTED

In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities" (SFAS 133), with
an amended effective date for fiscal years beginning after June 15, 2000. SFAS
133 requires that an entity recognize on its balance sheet all derivative
instruments as either assets or liabilities at their fair value. Changes in the
fair value of derivatives are recorded each period in current earnings or Other
comprehensive income, depending on whether a derivative is designated as part of
a hedge transaction, and, if it is, the type of hedge transaction. The Company
will adopt SFAS 133 as of January 1, 2001. Due to the Company's limited use of
derivative instruments, SFAS 133 is not expected to have a material effect on
the financial position or results of operations of the Company.

2.          DISCONTINUED DEFENSE BUSINESS

On August 25, 1997, the Company and FMC Corporation signed an agreement to sell
United Defense, L.P. for $850 million, and the sale was completed on October 6,
1997. Prior to the sale, FMC had been the managing general partner and 60% owner
of United Defense, L.P., while the Company owned the balance of 40% as the
limited partner. United Defense supplies ground combat and naval weapons
systems for the U.S. and military customers worldwide.

On the Consolidated Statement of Income under Discontinued Operations, "Equity
in income of defense business" includes equity income through August 1997 (the
measurement date) from the Company's 40% interest in United Defense, L.P. The
sale resulted in pre-tax cash proceeds to the Company in 1997 of $344 million
and resulted in an after tax gain on the sale of $150 million or $3.08 per
share after taking into account certain retained liabilities from the
partnership and estimated post-closing net worth adjustments, as well as
pre-partnership formation contingencies and other defense business
contingencies.

On the Consolidated Statement of Cash Flows for 1997, equity in income of the
defense business and distributions from the defense business through the
measurement date are included in "Equity in income of unconsolidated entities"
and "Dividends or distributions from unconsolidated entities", respectively.
Disbursements related to the discontinued defense business, principally legal
fees and settlements, are shown separately on the Consolidated Statement of Cash
Flows for 1997, 1998, and 1999.

As a result of reducing certain inventory quantities valued on the LIFO basis,
net income increased from that which would have been recorded under the FIFO
basis of valuation, by $1.1 million, $0.2 million and $0.1 million in 1999,
1998, and 1997, respectively.

6.       DEBT AND CREDIT AGREEMENTS

The Company has a $400 million Five-Year Competitive Advance and Revolving
Credit Facility ("credit facility") maturing in July 2001. Borrowings under this
agreement are available in U.S. dollars or Eurocurrencies and the credit
facility serves as back-up to the Company's U.S. commercial paper program.
Interest rates are either negotiated, based upon the U.S. federal funds
interbank market, prime, or based upon the London Interbank Offered Rate (LIBOR)
plus a margin. The Company pays a facility fee (0.08% per annum as of December
31, 1999) that varies based upon its credit ratings. At December 31, 1999 and
1998, there were no borrowings outstanding.

The Company can also issue up to $400 million of short-term notes in the U.S.
commercial paper market. In addition, the Company has a three billion Belgian
franc commercial paper program (approximately U.S. $75 million at December 31,
1999) which is used to fund the Company's international operations. The Company
limits the aggregate commercial paper and credit facility borrowings at any one
time to a maximum of $400 million. Commercial paper interest rates, which are
based on market conditions, have been lower than on comparable borrowings under
the credit facility. At December 31, 1999 and 1998, $233.7 million and $108.8
million of commercial paper was outstanding, respectively. Commercial paper is
classified as long-term debt at December 31, 1999 and 1998, because the Company
has the ability and intent to refinance it on a long-term basis through existing
long-term credit facilities.

Short-term debt amounted to $32.0 million and $46.8 million at December 31, 1999
and 1998, respectively. The weighted average interest rate for short-term
borrowings at December 31, 1999 and 1998 was 4.6% and 7.9%, respectively.

8.          EMPLOYEE BENEFIT PLANS

PENSION BENEFITS

The Company has pension and profit sharing retirement plans, most of which are
noncontributory, covering substantially all of its employees. The benefits for
salaried employees generally are based on years of service and the employee's
level of compensation during specified periods of employment. Plans covering
hourly employees generally provide benefits of stated amounts for each year of
service. The multi-employer plans in which the Company participates provide
benefits to certain unionized employees. The Company's funding policy for
qualified plans is consistent with statutory regulations and customarily equals
the amount deducted for income tax purposes. The Company's policy is to amortize
prior service costs over the average future service period of active plan
participants.

In 1997, the curtailment gain of $5.5 million was the result of a sizable
reduction in the number of employees under a plan related to a discontinued
facility. This gain, along with certain costs, was recorded under Other (income)
and expenses in the Consolidated Statement of Income.

POSTRETIREMENT BENEFITS

The Company has postretirement life insurance benefits for a majority of
employees, and postretirement health care benefits for a limited number of
employees mainly under plans related to acquired companies. The cost of life
insurance and health care benefits are accrued for current and future retirees
and are recognized as determined under the projected unit credit actuarial
method. Under this method, the Company's obligation for postretirement benefits
is to be fully accrued by the date employees attain full eligibility for such
benefits. The Company's postretirement health care and life insurance plans are
unfunded.

The postretirement benefit expense (health care and life insurance) was $0.4
million in 1999, $0.3 million in 1998, and $0.2 million in 1997. The components
of these expenses are not shown separately as they are not material.

The changes in the postretirement benefit liability recorded in the Consolidated
Balance Sheet are:

- ----------------------------------------------------------------------------------------------------
</TABLE>

For 1999, a one percent decrease in the health care cost trend rate would
decrease the cost component by $19 thousand and decrease the accumulated benefit
obligation by $405 thousand.

It is anticipated that the health care cost trend rate will decrease from 7.5%
in 2000 to 6.5% in the year 2003.

SAVINGS PLAN
The Company has a 401(k) savings plan which covers substantially all U.S.
employees with the exception of employees represented by a collective bargaining
agreement, unless the agreement expressly provides otherwise. Employee
contributions are generally determined as a percentage of covered employee's
compensation. The expense for contributions to the plan by the Company was (in
millions) $4.4, $4.8, and $4.5 for 1999, 1998, and 1997, respectively.

EXECUTIVE INCENTIVE COMPENSATION PLAN
Under the 1995 Executive Incentive Compensation Plan, the Management Development
and Compensation Committee awarded 60% of the value of any earned annual
incentive compensation award to be paid to participants in the form of cash and
40% in the form of restricted shares of the Company's common stock. Upon the
request of the participant, the Committee was authorized to make the incentive
award payable all in cash, subject to a 25% reduction in the total amount of the
award. Awards were made in February of the following year. The Company accrued
amounts based on performance reflecting the value of cash and common stock which
was anticipated to be earned for the year. Compensation expense relating to
these awards was (in millions) $3.8, $3.7, and $5.1 in 1999, 1998 and 1997,
respectively.

Effective January 1, 1999 the restricted stock portion of the compensation plan
was discontinued and the terms of the plan were amended to provide for payment
of the incentive compensation all in cash. On January 6, 1999 the Company
repurchased from the participants, at the original award value, the restricted
shares awarded in 1998. For all other shares, the restrictions were removed
effective January 6, 1999.

Cash payments for income taxes were (in millions) $50.7, $38.8, and $167.0, for
1999, 1998, and 1997, respectively. Approximately $5.4 million of the taxes paid
in 1998 and $100.0 million of the taxes paid in 1997 are related to the gain on
the disposal of the defense business.

9.      INCOME TAXES (CONTINUED)


At December 31, 1999, certain of the Company's subsidiaries had total available
net operating loss carryforwards ("NOLs") of approximately $27.8 million, of
which approximately $17.9 million may be carried forward indefinitely and $9.9
million have varying expiration dates. Included in the total are $8.7 million of
preacquisition NOLs.

During 1999 and 1998, $2.3 million and $4.4 million, respectively, of
preacquisition NOLs were utilized by the Company, resulting in tax benefits of
$0.8 million and $1.7 million, respectively.

The valuation allowance of $4.0 million and $6.3 million at December 31, 1999
and 1998, respectively, relates principally to cumulative unrelieved tax losses
which are uncertain as to realizability. To the extent that the preacquisition
NOLs are utilized in the future and the associated valuation allowance reduced,
the tax benefit will be allocated to reduce the cost in excess of net assets of
businesses acquired.

The change in the valuation allowances for 1999 and 1998 results primarily from
the utilization of international tax loss carryforwards and the release of
valuation allowances in certain international jurisdictions based on the
Company's reevaluation of the realizability of future benefits. The release of
valuation allowances in certain jurisdictions was allocated to reduce the cost
in excess of net assets of businesses acquired by $0.3 million in 1999. There
was no reduction in 1998.

10.     COMMITMENTS AND CONTINGENCIES

DISCONTINUED DEFENSE BUSINESS - CONTINGENCIES

FEDERAL EXCISE TAX AND OTHER MATTERS RELATED TO THE FIVE-TON TRUCK CONTRACT
In 1995, the Company, the United States Army ("Army"), and the United States
Department of Justice concluded a settlement of Harsco's previously reported
claims against the Army relating to Federal Excise Tax ("FET") arising under a
completed 1986 contract for the sale of five-ton trucks to the Army. On
September 27, 1995, the Army paid the Company $49 million in accordance with the
settlement terms. The Company released the Army from any further liability for
those claims, and the Department of Justice released the Company from a
threatened action for damages and civil penalties based on an investigation
conducted by the Department's Commercial Litigation Branch that had been pending
for several years.

The settlement preserves the rights of the parties to assert claims and defenses
under the Internal Revenue Code, and rights of the Army and the Company to claim
certain amounts that may be owed by either party to reconcile possible
underpayments or overpayments on the truck contract as part of the formal
contract close-out process.

The settlement does not resolve the claim by the Internal Revenue Service
("IRS") that, contrary to the Company's position, certain cargo truck models
sold by the Company should be considered to have gross vehicle weights in excess
of the 33,000 pound threshold under FET law, are not entitled to an exemption
from FET under any other theory, and therefore are taxable. In 1999, the IRS
assessed an increase in FET of $30.4 million plus penalties of $9.3 million and
applicable interest currently estimated to be $45.5 million. In October 1999,
the Company posted an $80 million bond required as security by the IRS. This
increase in FET takes into account offsetting credits of $9.2 million, based on
a partial allowance of the Company's $31.9 million claim that certain truck
components are exempt from FET. The IRS disallowed in full the Company's
additional claim that it is entitled to the entire $52 million of FET (plus
applicable interest currently estimated by the Company to be $41.7 million) the
Company has paid on the five-ton trucks, on the grounds that such trucks qualify
for the FET exemption applicable to certain vehicles specially designed for the
primary function of off-highway transportation. In the event that the Company
ultimately receives from the IRS a refund of tax (including applicable interest)
with respect to which the Company has already received reimbursement from the
Army, the refund would be allocated between the Company and the Army. The
Company plans to vigorously contest the IRS assessment in the U.S. Court of
Federal Claims. Although there is risk of an adverse outcome, both the Company
and the Army believe that the cargo trucks are not taxable. No recognition has
been given in the accompanying financial statements for the Company's claims
with the IRS.

- --------------------------------------------------------------------------------
10.     COMMITMENTS AND CONTINGENCIES (CONTINUED)

The settlement agreement with the Army preserves the Company's right to seek
reimbursement of after-imposed tax from the Army in the event that the cargo
trucks are determined to be taxable, but the agreement limits the reimbursement
to a maximum of $21 million. Additionally, in an earlier contract modification,
the Army accepted responsibility for $3.6 million of the potential tax, bringing
its total potential responsibility up to $24.6 million.

Under the settlement, the Army agreed that if the cargo trucks are determined to
be taxable, the 1993 decision of the Armed Services Board of Contract Appeals
(which ruled that the Company is entitled to a price adjustment to the contract
for reimbursement of FET paid on vehicles that were to be delivered after
October 1, 1988) will apply to the question of the Company's right to
reimbursement from the Army for after-imposed taxes on the cargo trucks. In the
Company's view, application of the 1993 decision will favorably resolve the
principal issues regarding any such future claim by the Company. Therefore, the
Company believes that even if the cargo trucks are ultimately held to be
taxable, the Army would be obligated to reimburse the Company for a majority of
the tax, (but not interest or penalty, if any), resulting in a net maximum
liability for the Company of $5.8 million plus penalties and applicable interest
currently estimated to be $9.3 million and $45.5 million, respectively. The
Company believes it is unlikely that resolution of this matter will have a
material adverse effect on the Company's financial position, however, it could
have a material effect on quarterly or annual results of operations.

OTHER DEFENSE BUSINESS LITIGATION
In 1992, the U.S. Government filed a counterclaim against the Company in a civil
suit alleging violations of the False Claims Act and breach of a contract to
supply M109A2 Self-Propelled Howitzers. In May 1999, the Company and the U.S.
Government settled. Under the settlement agreement, Harsco paid the U.S.
Government $11 million and both parties released all claims in the case. The
settlement payment was charged against an existing reserve in the second quarter
of 1999.

In 1992, the United States Government through its Defense Contract Audit Agency
commenced an audit of certain contracts for sale of tracked vehicles by the
Company to foreign governments, which were financed by the United States
Government through the Defense Security Assistance Agency. In September 1994,
the Company received a subpoena issued by the Department of Defense Inspector
General seeking various documents relating to issues raised in the audit.

10.     COMMITMENTS AND CONTINGENCIES (CONTINUED)

The Government subsequently subpoenaed a number of former employees of the
Company's divested defense business to testify before a grand jury and issued
grand jury subpoenas to the Company for additional documents. On December 22,
1999, the Company announced that it reached agreement with the U.S. Government
on behalf of its former BMY Combat Systems Division to settle the matter. Under
the agreement, BMY Combat Systems pled guilty to a one-count misdemeanor
relating to submitting advance payment certifications which resulted in BMY
receiving a portion of the payments for the contract prematurely. Harsco will
pay the Government a $200,000 fine plus $10.8 million in damages for a total of
$11 million.

The settlement, which is subject to acceptance by the U.S. District Court, ends
the Government's investigation and releases Harsco and BMY from further
liability for the issues under investigation. Harsco will charge the payment
against an existing reserve, resulting in no charge to the Company's earnings.
Based on the terms of the settlement, the Company expects to pay the $11 million
in the second quarter of 2000, following the Court's entry of judgment.

CONTINUING OPERATIONS - CONTINGENCIES

ENVIRONMENTAL
The Company is involved in a number of environmental remediation investigations
and clean-ups and, along with other companies, has been identified as a
"potentially responsible party" for certain waste disposal sites. While each of
these matters is subject to various uncertainties, it is probable that the
Company will agree to make payments toward funding certain of these activities
and it is possible that some of these matters will be decided unfavorably to the
Company. The Company has evaluated its potential liability, and its financial
exposure is dependent upon such factors as the continuing evolution of
environmental laws and regulatory requirements, the availability and application
of technology, the allocation of cost among potentially responsible parties, the
years of remedial activity required and the remediation methods selected. The
Consolidated Balance Sheet at December 31, 1999, and 1998 includes an accrual of
$3.0 million and $4.9 million, respectively, for environmental matters. The
amounts affecting pre-tax earnings related to environmental matters totaled $0.7
million of income for the year 1999, $0.8 million of expense for the year 1998
and $1.7 million of expense for the year 1997.

The liability for future remediation costs is evaluated on a quarterly basis.
Actual costs to be incurred at identified sites in future periods may vary from
the estimates, given inherent uncertainties in evaluating environmental
exposures. The Company does not expect that any sum it may have to pay in
connection with environmental matters in excess of the amounts recorded or
disclosed above would have a material adverse effect on its financial position
or results of operations.

OTHER
The Company is subject to various other claims, legal proceedings, and
investigations covering a wide range of matters that arose in the ordinary
course of business. In the opinion of management, all such matters are
adequately covered by insurance or by accruals, and if not so covered, are
without merit or are of such kind, or involve such amounts, that would not have
a material adverse effect on the financial position or results of operations of
the Company.

11.     CAPITAL STOCK

The authorized capital stock consists of 150,000,000 shares of common stock and
4,000,000 shares of preferred stock, both having a par value of $1.25 per share.
The preferred stock is issuable in series with terms as fixed by the Board of
Directors. None of the preferred stock has been issued. On June 24, 1997, the
Company adopted a revised Shareholder Rights Plan to replace the Company's 1987
Plan which expired on September 28, 1997. Under the new Plan, the Board declared
a dividend to shareholders of record on September 28, 1997, of one right for
each share of common stock. The rights may only be exercised if, among other
things, a person or group has acquired 15% or more, or intends to commence a
tender offer for 20% or more, of the Company's common stock. Each right entitles
the holder to purchase 1/100th share of a new Harsco Junior Participating
Cumulative Preferred Stock at an exercise price of $150. Once the rights become
exercisable, if any person acquires 20% or more of the Company's common stock,
the holder of a right will be entitled to receive common stock calculated to
have a value of two times the exercise price of the right. The rights, which
expire on September 28, 2007, do not have voting power, and may be redeemed by
the Company at a price of $.05 per right at any time until the 10th business day
following public announcement that a person or group has accumulated 15% or more
of the Company's common stock. At December 31, 1999, 750,000 shares of $1.25 par
value preferred stock were reserved for issuance upon exercise of the rights.

In November 1998, the Board of Directors authorized the purchase, over a
one-year period, of 2,000,000 shares of the Company's common stock. The Company
purchased 877,500 shares of this authorization in 1998. The Board of Directors
subsequently increased the authorization by 2,000,000 shares in January 1999.
Through December 31, 1999, 3,143,646 shares of common stock were purchased under
these authorizations. This leaves 856,354 shares remaining under the
authorization. In January 2000, the Board of Directors extended the share
purchase authorization through January 25, 2001.

In 1999, additional share repurchases of 58,155, net of issues, were made
principally as part of the 1995 Executive Compensation Plan.

The Company has granted stock options to officers, certain key employees, and
directors for the purchase of its common stock under two shareholder approved
plans. The 1995 Executive Incentive Compensation Plan authorizes the issuance of
up to 4,000,000 shares of the Company's common stock for use in paying incentive
compensation awards in the form of restricted stock and stock options. The 1995
Non-Employee Directors' Stock Plan authorizes the issuance of up to 300,000
shares of the Company's common stock for stock option awards. Options are
granted at fair market value at date of grant and become exercisable commencing
one year later. The options expire ten years from the date of grant. Upon
shareholder approval of these two plans in 1995, the Company terminated the use
of the 1986 stock option plan for granting of stock option awards. At December
31, 1999, there were 2,729,158 and 220,000 shares available for granting stock
options under the 1995 Executive Incentive Compensation Plan and the 1995
Non-Employee Directors' Stock Plan, respectively.

13.    FINANCIAL INSTRUMENTS

OFF-BALANCE SHEET RISK
As collateral for performance and to ceding insurers, the Company is
contingently liable under standby letters of credit and bonds in the amount of
$165.9 million and $38.7 million at December 31, 1999 and 1998, respectively.
These standby letters of credit and bonds are generally in force for up to four
years. Certain issues have no scheduled expiration date. The Company pays fees
to various banks and insurance companies that range from 0.08 to 1.9 percent per
annum of their face value. If the Company were required to obtain replacement
standby letters of credit and bonds as of December 31, 1999 for those currently
outstanding, it is the Company's opinion that the replacement costs would not
vary significantly from the present fee structure.

At December 31, 1999 and 1998, the Company had $19.2 million and $18.3 million,
respectively, of forward foreign currency exchange contracts outstanding. These
contracts are part of a worldwide program to minimize foreign currency exchange
operating income and balance sheet exposure. The unsecured contracts mature
within 12 months and are with major financial institutions. The Company is
exposed to credit loss in the event of non-performance by the other parties to
the contracts. The Company evaluates the credit worthiness of the
counterparties' financial condition and does not expect default by the
counterparties.

FOREIGN EXCHANGE RISK MANAGEMENT
The Company generally has currency exposures in thirty-two countries. The
Company's primary foreign currency exposures are in United Kingdom, France,
Canada, South Africa, Brazil, Germany, Australia, and Mexico.

Forward foreign currency exchange contracts are used to hedge commitments, such
as foreign currency debt, firm purchase commitments, and foreign currency cash
flows for certain export sales transactions.

At December 31, 1999, the Company had entered into forward exchange contracts in
euros and British pounds, which were used to hedge certain future payments
between the Company and its various subsidiaries. These forward contracts do not
qualify as hedges for financial reporting purposes. At December 31, 1999, the
Company had recorded net losses of $0.6 million on these contracts. These losses
were generally offset by gains on the hedged items. In January 2000, the euro
contract was extended to March 18, 2000. The Company also had forward exchange
contracts in French francs and British pounds, which were used to hedge
equipment purchases. Since these contracts hedge identifiable foreign currency
firm commitments, the losses were deferred and will be accounted for as part of
the underlying transactions.

13.    FINANCIAL INSTRUMENTS (CONTINUED)

CONCENTRATIONS OF CREDIT RISK
Financial instruments, which potentially subject the Company to concentrations
of credit risk, consist principally of cash and cash equivalents, investments,
and accounts receivable. The Company places its cash and cash equivalents with
high quality financial institutions and, by policy, limits the amount of credit
exposure to any one institution. Concentrations of credit risk with respect to
accounts receivable are limited due to the Company's large number of customers
and their dispersion across different industries and geographies. The Company
generally does not require collateral or other security to support customer
receivables.

FAIR VALUE OF FINANCIAL INSTRUMENTS
The major methods and assumptions used in estimating the fair values of
financial instruments are:

         CASH AND CASH EQUIVALENTS
         The carrying amount approximates fair value due to the relatively short
         period to maturity of these instruments.

         LONG-TERM DEBT
         The fair value of the Company's long-term debt is estimated based on
         the quoted market prices for the same or similar issues or on the
         current rates offered to the Company for debt of the same remaining
         maturities.

         FOREIGN CURRENCY EXCHANGE CONTRACTS
         The fair value of foreign currency exchange contracts are estimated by
         obtaining quotes from brokers.

14.      INFORMATION BY SEGMENT AND GEOGRAPHIC AREA

The Company reports information about its operating segments according to the
"management approach". The management approach is based on the way management
organizes the segments within the enterprise for making operating decisions and
assessing performance.

The Company's reportable segments are identified based upon differences in
products, services, and markets served. The Company's business units are
aggregated into three reportable segments. The three reportable segments and the
type of products and services offered include:

HARSCO MILL SERVICES
This segment provides metal reclamation and other mill services, principally for
the global steel industry. Mill services include slag processing, marketing, and
disposal; slab management systems; materials handling and scrap management
programs; in-plant transportation; and a variety of environmental services.
Similar services are provided to non-ferrous metallurgical industries, such as
aluminum, nickel, and copper. Also, slag recovery services are provided to
electric utilities from which granules for asphalt roofing shingles and slag
abrasives for industrial surface preparation are derived.

HARSCO GAS AND FLUID CONTROL
Major products and services are gas containment cylinders and tanks, including
cryogenic equipment; valves, regulators, and gauges, including scuba and life
support equipment; industrial pipe fittings; and air-cooled heat exchangers.

Major customers include various industrial markets; hardware, plumbing, and
petrochemical sectors; natural gas and process industries; propane, compressed
gas, life support, scuba, and refrigerant gas industries; gas equipment
companies; welding distributors; medical laboratories; beverage carbonation
users; and the animal husbandry industry.

HARSCO INFRASTRUCTURE
Major products and services include railway maintenance-of-way equipment and
services; scaffolding, shoring, and concrete forming products and erection and
dismantling services; bridge decking and industrial grating; process equipment,
including industrial blenders, dryers, mixers, water heaters, boilers, and heat
transfer equipment.

Products and services are provided to private and government-owned railroads
worldwide; urban mass transit operators; public utilities; industrial plants;
the oil, chemical, petrochemical, and process industries; bridge repair
companies; commercial and industrial construction firms; and infrastructure
repair and maintenance markets. Other customers include the chemical, food
processing, and pharmaceutical industries; and institutional building and
retrofit markets.

OTHER INFORMATION
The measurement basis of segment profit or loss is income after taxes from
continuing operations. Interest income is recorded by each segment as incurred.
Interest expense is allocated to the segments based on actual interest expense
incurred by international operations and based on internal borrowings at an
estimated weighted average interest rate for domestic operations. Income taxes
are allocated to the segments based on actual income tax expense incurred, or
where aggregated for tax purposes, based on the effective income tax rates for
the countries in which they operate. The operations of the Company in any one
country, except the United States, do not account for more than 10% of sales and
no single customer represented 10% or more of the Company's sales, during 1999,
1998, and 1997. There are no significant intersegment sales.

Corporate assets include principally cash, investments, prepaid pension costs,
and United States deferred taxes. Assets in the United Kingdom represent 12% of
total segment assets as of December 31, 1999 and 1998 and are disclosed
separately in the geographic area information.

15.    OTHER (INCOME) AND EXPENSES AND SPECIAL CHARGES AND (GAINS) (CONTINUED)

NET GAINS
Net gains for 1998 consist principally of a pre-tax net gain of $27 million
recorded on the October 1998 sale of the Nutter Engineering unit of the Harsco
Gas and Fluid Control Segment. Such gains are reflected as adjustments to
reconcile net income to net cash provided by operating activities in the
Consolidated Statement of Cash Flows. Total proceeds associated with 1998
special gains were $42.9 million and are included in proceeds from the sale of
businesses and property, plant and equipment in the investing activities section
of the Consolidated Statement of Cash Flows. Other related information
concerning dispositions is discussed in Note 3.

IMPAIRED ASSET WRITE-DOWNS
Impaired asset write-downs for 1999 include a $1.9 million pre-tax, non-cash,
write-down of the Company's investment in Bio-Oxidation Services Inc. which is
included in the Harsco Gas and Fluid Control Segment. The Company's investment
in Bio-Oxidation Services Inc. is being held for disposal. The write-down amount
was measured on the basis of the lower of carrying amount or fair value less
cost to sell. Fair value was determined using available information based upon
the estimated amount at which the assets could be sold in a current transaction
between willing parties. The investment carrying value as of December 31, 1999
was $6.6 million. For the year ended December 31, 1999, Bio-Oxidation Services
Inc. recorded a pre-tax loss of $2.3 million which includes the asset write-down
of $1.9 million. The Company estimates that the disposal will occur during 2000.

Impaired asset write-downs for 1998 include a $6.1 million pre-tax, non-cash,
write-down of the Company's investment in Bio-Oxidation Services Inc. The
investment carrying value as of December 31, 1998 was $7.6 million. For the year
ended December 31, 1998 Bio-Oxidation Services Inc. recorded a pre-tax loss of
$9.8 million which includes the asset write-down of $6.1 million.

Impaired asset write-downs for 1998 also include a $6.1 million pre-tax,
non-cash, write-down of assets, principally property, plant and equipment in the
Harsco Mill Services Segment. The write-down became necessary as a result of
significant adverse changes in the international economic environment and the
steel industry. Impairment loss was measured as the amount by which the carrying
amount of assets exceeded their estimated fair value. Fair value was estimated
based upon the expected future realizable net cash flows. In September 1999,
assets associated with a substantial portion of this provision were sold in
conjunction with the termination settlement of a contract in Russia.

Non-cash impaired asset write-downs are included in Other (income) and expenses
in the Consolidated Statement of Cash Flows as adjustments to reconcile net
income to net cash provided by operating activities.

15.    OTHER (INCOME) AND EXPENSES AND SPECIAL CHARGES AND (GAINS) (CONTINUED)

EMPLOYEE TERMINATION BENEFIT COSTS
Employee termination benefit costs consist principally of severance arrangements
to employees terminated as a result of management reorganization actions. Under
these reorganization actions, the Company's management has established and
approved specific plans of termination. Details of the termination benefit plans
have been communicated to the affected employees prior to recognition of related
provisions. Non-cash charges for employee termination benefit costs are included
as adjustments to reconcile net income to net cash provided by operating
activities in the Consolidated Statement of Cash Flows.

During 1999, $2.9 million of reorganization expense related to employee
termination benefits was incurred, principally in the Harsco Mill Services
Segment, primarily in France and the United Kingdom. In 1999, 220 employees were
included in employee termination arrangements initiated by the Company and
approximately $1.8 million of cash payments were made under such arrangements.
The payments are reflected as uses of operating cash in the Consolidated
Statement of Cash Flows.

During 1998, $6.5 million of reorganization expense related to employee
termination benefits was incurred, principally in the Harsco Mill Services
Segment primarily in South Africa, United States, France, and Germany. In 1998,
approximately 670 employees were included in employee termination arrangements
initiated by the Company and approximately $2.4 million of cash payments were
made under such arrangements. An additional $3.3 million was disbursed in 1999
for the 1998 reorganization actions.

COSTS TO EXIT ACTIVITIES
Costs to exit activities consist of incremental direct costs of reorganization
actions and lease run-out costs. Such costs are recorded when a specific exit
plan is approved by management. Relocation expenses, such as employee moving
costs, are classified as exit costs and are expensed as incurred. Other costs
classified in this category are generally expensed as incurred.

During 1998, $1.0 million and $0.8 million of exit costs, principally relocation
expenses, were included in the Harsco Mill Services and Harsco Infrastructure
Segments, respectively.

During 1997, $1.5 million of exit costs were included in the Harsco Mill
Services Segment. These costs resulted principally from the expiration or
termination of contracts at certain mill sites, as well as facility relocation
costs.

         Condensed financial information of the registrant is omitted since
         there are no substantial amounts of "restricted net assets" applicable
         to the Company's consolidated subsidiaries.

         Financial statements of 50% or less owned unconsolidated companies are
         not submitted inasmuch as (1) the registrant's investment in and
         advances to such companies do not exceed 20% of the total consolidated
         assets, (2) the registrant's proportionate share of the total assets of
         such companies does not exceed 20% of the total consolidated assets,
         (3) the registrant's equity in the income from continuing operations
         before income taxes of such companies does not exceed 20% of the total
