The Company reports segment information using the "management approach" in
accordance with SFAS No. 131, "Disclosures about Segments of an Enterprise and
Related Information" ("SFAS 131"). This approach is based on the way management
organizes and reports 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.
These segments and the types of products and services offered are more fully
described below.

In 2006, 2005 and 2004, the United States contributed sales of $1.3 billion,
$1.2 billion and $1.0 billion, equal to 38%, 42% and 42% of total sales,
respectively. In 2006, 2005 and 2004, the United Kingdom contributed sales of
$0.7 billion, $0.5 billion and $0.5 billion, respectively, equal to 20%, 20% and
21% of total sales, respectively. One customer represented 10% of the Company's
sales during 2006. No customer represented 10% or more of the Company's sales in
2005 and 2004. There were no significant inter-segment sales.

(b)  Financial Information about Segments

Financial information concerning industry segments is included in Note 14,
Information by Segment and Geographic Area, to the Consolidated Financial
Statements under Part II, Item 8, "Financial Statements and Supplementary Data."

(c)  Narrative Description of Business

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

      MILL SERVICES SEGMENT - 40% OF CONSOLIDATED SALES FOR 2006

      The Mill Services Segment, which consists of the MultiServ Division, is
      the Company's largest operating segment in terms of revenues and operating
      income. MultiServ is the world's largest provider of on-site, outsourced
      mill services to the global steel and metals industries. MultiServ
      provides its services on a long-term contract basis, supporting each stage
      of the metal-making process from initial raw material handling to
      post-production by-product processing and on-site recycling. Working as a
      specialized, high-value-added services provider, MultiServ rarely takes
      ownership of its customers' raw materials or finished products. Similar
      services are provided to the producers of non-ferrous metals, such as
      aluminum, copper and nickel. The Company's multi-year Mill Services
      contracts had estimated future revenues of $4.4 billion at December 31,
      2006. This provides the Company with a substantial base of long-term
      revenues. Approximately 60% of these revenues are expected to be
      recognized by December 31, 2009. The remaining revenues are expected to be
      recognized principally between January 1, 2010 and December 31, 2015.

      MultiServ's geographic reach to over 30 countries, and its increasing
      range of services, enhance the Company's financial and operating balance.
      In 2006, this Segment's revenues were generated in the following regions:

                              MILL SERVICES SEGMENT

      access solutions. The U.K.-based SGB

                                       -3-


      Group Division operates from a network of international branches
      throughout Europe, the Middle East and Asia/Pacific; the Germany-based
      Hunnebeck Division serves Europe, the Middle East and South America while
      the U.S.-based Patent Construction Systems Division serves North America.
      Major services include the rental of concrete shoring and forming systems,
      scaffolding and powered access equipment for non-residential construction
      and international multi-dwelling residential construction projects; as
      well as a variety of other access services including project engineering
      and equipment erection and dismantling and, to a lesser extent, access
      equipment sales.

      The Company's access services are provided through branch locations in
      approximately 30 countries plus export sales worldwide. In 2006, this
      Segment's revenues were generated in the following regions:

                                 ACCESS SERVICES SEGMENT
            ----------------------------------------------------------------

            Asia/Pacific                                        1%
            Latin America                                       1%

      For 2006, 2005 and 2004, the Access Services Segment's percentage of the
      Company's consolidated sales was 31%, 29% and 28%, respectively.

      The Engineered Products and Services ("all other") Category includes the
      Harsco Track Technologies, Reed Minerals, IKG Industries, Air-X-Changers,
      and Patterson-Kelley Divisions. Approximately 88% of this category's
      revenues originate in the United States.

      Export sales for this Category totaled $96.6 million, $116.6 million and
      $101.2 million in 2006, 2005 and 2004, respectively. In 2006, 2005 and
      2004, export sales for the Harsco Track Technologies Division were $51.5
      million, $80.0 million and $76.3 million, respectively, which included
      sales to Europe, Asia, the Middle East and Africa. The increased export
      sales for the Division in 2005 and 2004 were due to large shipments to
      China.

      Harsco Track Technologies is a global provider of equipment and services
      to maintain, repair and construct railway track. The Company's railway
      track maintenance services provide high-technology comprehensive track

      government-owned railroads and urban transit systems worldwide.

      Reed Minerals' roofing granules and industrial abrasives are produced from
      power-plant utility coal slag at a number of locations throughout the
      United States. The Company's Black Beauty(R) abrasives are used for
      industrial surface preparation, such as rust removal and cleaning of

      GAS TECHNOLOGIES SEGMENT - 12% OF CONSOLIDATED SALES FOR 2006

      The Gas Technologies Segment includes the Company's Harsco GasServ
      Division. The Segment's manufacturing and service facilities in the United
      States, Europe, Australia, Malaysia and China comprise an integrated
      manufacturing network for gas containment and control products. This
      global operating presence and product breadth provide economies of scale
      and multiple code production capability, enabling Harsco GasServ to serve
      as a primary source to the world's leading industrial gas producers and
      distributors, as well as regional and local customers. In 2006,
      approximately 85% of this Segment's revenues were generated in the United
      States.

      The Company's gas containment products include cryogenic gas storage
      tanks; high pressure and acetylene gas cylinders; propane tanks; and

      Company's consolidated sales was 12%, 13% and 14%, respectively.

      In January 2007, the Company's Board of Directors approved the divestiture
      of this Segment. The Company expects this divestiture to occur in the
      second half of 2007.

      (1)           (i) The products and services of the Company include a
                    number of product groups. These product groups are more
                    fully discussed in Note 14, Information by Segment and
                    Geographic Area, to the Consolidated Financial Statements
                    under Part II, Item 8, "Financial Statements and
                    Supplementary Data." The product groups that contributed 10%
                    or more as a percentage of consolidated sales in any of the
                    last three fiscal years are set forth in the following
                    table:

      (1)   (ii)    New products and services are added from time to time;
                    however, in 2006 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
                    are usually readily available. The profitability of the
                    Company's manufactured products are affected by changing
                    purchase prices of steel and other materials and
                    commodities. Beginning in 2004, the price paid for steel and
                    certain other commodities increased significantly compared
                    with prior years. Although these costs moderated in 2005,
                    such costs increased during 2006. If steel or other material
                    costs associated with the Company's manufactured products
                    continue to increase and the costs cannot be passed on to
                    the Company's customers, operating income would be adversely
                    impacted. Additionally, decreased availability of steel or
                    other materials, such as carbon fiber used to manufacture
                    filament-wound composite cylinders, could affect the
                    Company's ability to produce manufactured products in a
                    timely manner. If the Company cannot obtain the necessary
                    raw materials for its manufactured products, then revenues,
                    operating income and cash flows will be adversely impacted.

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

      (1)   (v)     The Company furnishes products and materials and certain
                    industrial services within the Access Services and Gas
                    Technologies Segments and the Engineered Products and
                    Services ("all other") Category that are seasonal in nature.
                    As a result, the Company's sales and net income for the
                    first quarter ending

                                       -5-


                    March 31 are normally lower than the second, third and
                    fourth quarters. Additionally, the Company has historically
                    generated the majority of its cash flows in the third and
                    fourth quarters (periods ending September 30 and December
                    31). This is a direct result of normally higher sales and
                    income during the latter part of the year. The Company's
                    historical revenue patterns and cash provided by operating
                    activities were as follows:

        (a) Does not total due to rounding.

      (1)   (vi)    The practices of the Company relating to working capital are
                    similar to those practices of other industrial service
                    providers or manufacturers servicing both domestic and
                    international industrial services and commercial markets.
                    These practices include the following:

                    o    Standard accounts receivable payment terms of 30 days
                         to 60 days, with progress payments required for certain
                         long-lead-time or large orders. Payment terms are
                         longer in certain international markets.

                    o    Standard accounts payable payment terms of 30 days to
                         90 days.

                    o    Inventories are maintained in sufficient quantities to
                         meet forecasted demand. Due to the time required to
                         manufacture certain railway maintenance equipment to
                         customer specifications, inventory levels of this
                         business tend to increase for an extended time during
                         the production phase and then decline when the
                         equipment is sold.

      (1)   (vii)   No single customer represented 10% or more of the Company's
                    sales in 2005 and 2004. However, in 2006 one customer
                    represented 10% of its sales. In addition, the Mill Services
                    Segment is dependent largely on the global steel industry
                    and in 2006, 2005 and 2004, there were two customers that
                    each provided in excess of 10% of this Segment's revenues
                    under multiple long-term contracts at several mill sites.
                    The loss of any one of the contracts would not have a
                    material adverse effect upon the Company's financial
                    position or cash flows; however, it could have a material
                    effect on quarterly or annual results of operations.
                    Additionally, these customers have significant accounts
                    receivable balances. Further consolidation in the global
                    steel industry is probable. Should transactions occur
                    involving some of the Company's larger steel industry
                    customers, it would result in an increase in concentration
                    of credit risk for the Company. If a large customer were to
                    experience financial difficulty, or file for bankruptcy
                    protection, it could adversely impact the Company's income,
                    cash flows, and asset valuations. As part of its credit risk
                    management practices, the Company closely monitors the
                    credit standing and accounts receivable position of its
                    customer base.

                                       -6-


      (1)   (viii)  Backlog of orders was $301.0 million and $275.8 million as
                    of December 31, 2006 and 2005, respectively. It is expected
                    that approximately 20% of the total backlog at December 31,
                    2006 will not be filled during 2007. The Company's backlog
                    is seasonal in nature and tends to follow in the same
                    pattern as sales and net income which is discussed in
                    section (1) (v) above. Order backlog for scaffolding,
                    shoring and forming services of the Access Services Segment
                    is excluded from the above amounts. These amounts are
                    generally not quantifiable due to short order lead times for
                    certain services, the nature and timing of the products and
                    services provided and equipment rentals with the ultimate
                    length of the rental period often unknown. Backlog for
                    roofing granules and slag abrasives is not included in the
                    total backlog because it is generally not quantifiable, due
                    to the short order lead times of the products provided.
                    Contracts for the Mill Services Segment are also excluded
                    from the total backlog. These contracts have estimated
                    future revenues of $4.4 billion at December 31, 2006. For
                    additional information regarding backlog, see the Backlog
                    section included in Part II, Item 7, "Management's
                    Discussion and Analysis of Financial Condition and Results
                    of Operations."

      (1)   (ix)    At December 31, 2006, the Company had no material contracts
                    that were subject to renegotiation of profits or termination
                    at the election of the U.S. Government.

      (1)   (x)     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 $3.0
                    million, $2.7 million and $2.6 million in 2006, 2005 and
                    2004, respectively. For additional information regarding
                    product development activities, see the Research and
                    Development section included in Part II, Item 7,
                    "Management's Discussion and Analysis of Financial Condition
                    and Results of Operations."

      (1)  (xii)    The Company has become subject, as have others, to stringent
                    air and water quality control legislation. In general, the
                    Company has not experienced substantial difficulty complying
                    with these environmental regulations in the past, and does
                    not anticipate making any material capital expenditures for
                    environmental control facilities. While the Company expects
                    that environmental regulations may expand, and that 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, Commitments and
                    Contingencies, to the Consolidated Financial Statements
                    included in Part II, Item 8, "Financial Statements and
                    Supplementary Data."

      (1)   (xiii)  As of December 31, 2006, the Company had approximately
                    21,500 employees.

(d)  Financial Information about Geographic Areas

Financial information concerning foreign and domestic operations is included in
Note 14, Information by Segment and Geographic Area, to the Consolidated
Financial Statements under Part II, Item 8, "Financial Statements and
Supplementary Data." Export sales totaled $162.6 million, $171.0 million and
$139.3 million in 2006, 2005 and 2004, respectively.

Business."


ITEM 1A. RISK FACTORS

      MARKET RISK.

In the normal course of business, the Company is routinely subjected to a
variety of risks. In addition to the market risk associated with interest rate
and currency movements on outstanding debt and non-U.S. dollar-denominated
assets and liabilities, other examples of risk include collectibility of
receivables, volatility of the financial markets and their effect on pension
plans, and global economic and political conditions.

                                       -7-


CYCLICAL INDUSTRY AND ECONOMIC CONDITIONS MAY ADVERSELY AFFECT THE COMPANY'S
BUSINESSES.

The Company's businesses are subject to general economic slowdowns and cyclical
conditions in the industries served.  In particular,

o     The Company's Mill Services business may be adversely impacted by
      slowdowns in steel mill production, excess capacity, consolidation or
      bankruptcy of steel producers or a reversal or slowing of current
      outsourcing trends in the steel industry;

o     The Company's Access Services business may be adversely impacted by
      slowdowns in non-residential or commercial construction and the volatility
      of annual industrial and building maintenance cycles;

o     The railway track maintenance business may be adversely impacted by
      developments in the railroad industry that lead to lower capital spending
      or reduced maintenance spending;

o     The industrial abrasives and roofing granules business may be adversely
      impacted by reduced home resales or economic conditions that slow the rate
      of residential roof replacement, or by slowdowns in the industrial and
      infrastructure refurbishment industries;

o     The industrial grating business may be adversely impacted by slowdowns in
      non-residential construction and industrial production;

o     The air-cooled heat exchangers business is affected by cyclical conditions
      present in the natural gas industry. A high demand for natural gas is
      currently creating increased demand for the Company's air-cooled heat
      exchangers. However, a slowdown in natural gas production could adversely
      affect this business; and

o     The Company's Gas Technologies business may be adversely impacted by
      reduced industrial production and lower demand for industrial gases,
      slowdowns in demand for medical cylinders and valves, or lower demand for
      natural gas vehicles.

      THE COMPANY'S DEFINED BENEFIT PENSION EXPENSE IS DIRECTLY AFFECTED BY THE
      EQUITY AND BOND MARKETS AND A DOWNWARD TREND IN THOSE MARKETS COULD
      ADVERSELY IMPACT THE COMPANY'S FUTURE EARNINGS. AN UPWARD TREND IN THE
      EQUITY AND BOND MARKETS COULD POSITIVELY AFFECT THE COMPANY'S FUTURE
      EARNINGS.

In addition to the economic issues that directly affect the Company's
businesses, changes in the performance of equity and bond markets, particularly
in the United Kingdom and the United States, impact actuarial assumptions used
in determining annual pension expense, pension liabilities and the valuation of
the assets in the Company's defined benefit pension plans. The downturn in
financial markets during 2000, 2001 and 2002 negatively impacted the Company's
pension expense and the accounting for pension assets and liabilities. This
resulted in an increase in pre-tax defined benefit pension expense from
continuing operations of approximately $20.8 million for calendar year 2002
compared with 2001 and $17.7 million for calendar year 2003 compared with 2002.
The upturn in certain financial markets beginning in 2003 and certain plan
design changes (discussed below) contributed to a decrease in pre-tax defined
benefit pension expense from continuing operations of approximately $1.6 million
for 2006 compared with 2005, approximately $3.8 million for 2005 compared with
2004, and approximately $5.4 million for 2004 compared with 2003. An upward
trend in capital markets would likely result in a decrease in future unfunded
obligations and pension expense. This could also result in an increase to
Stockholders' Equity and a decrease in the Company's statutory funding
requirements. If the financial markets deteriorate, it would most likely have a
negative impact on the Company's pension expense and the accounting for pension
assets and liabilities. This could result in a decrease to Stockholders' Equity
and an increase in the Company's statutory funding requirements.

In response to the adverse market conditions, during 2002 and 2003 the Company
conducted a comprehensive global review of its pension plans in order to
formulate a plan to make its long-term pension costs more predictable and
affordable. The Company implemented design changes for most of these plans
during 2003. The principal change involved converting future pension benefits
for many of the Company's non-union employees in both the U.K. and U.S. from
defined benefit plans to defined contribution plans as of January 1, 2004. This
conversion is expected to make the Company's pension expense more predictable
and affordable and less sensitive to changes in the financial markets.

The Company's pension committee continues to evaluate alternative strategies to
further reduce overall pension expense including the on-going evaluation of
investment fund managers' performance; the balancing of plan assets

                                       -8-


and liabilities; the risk assessment of all multi-employer pension plans; the
possible merger of certain plans; the consideration of incremental cash
contributions to certain plans; and other changes that are likely to reduce
future pension expense volatility and minimize risk.

      THE COMPANY'S GLOBAL PRESENCE SUBJECTS IT TO A VARIETY OF RISKS ARISING
      FROM DOING BUSINESS INTERNATIONALLY.

The Company operates in 46 countries, including the United States. The Company's
global footprint exposes it to a variety of risks that may adversely affect
results of operations, cash flows or financial position. These include the
following:

o    periodic economic downturns in the countries in which the Company does
     business;

o    fluctuations in currency exchange rates;

o    customs matters and changes in trade policy or tariff regulations;

o    imposition of or increases in currency exchange controls and hard currency
     shortages;

o    changes in regulatory requirements in the countries in which the Company
     does business;

o    higher tax rates and potentially adverse tax consequences including
     restrictions on repatriating earnings, adverse tax withholding requirements
     and "double taxation ";

o    longer payment cycles and difficulty in collecting accounts receivable;

o    complications in complying with a variety of international laws and
     regulations;

o    political, economic and social instability, civil unrest and armed
     hostilities in the countries in which the Company does business;

o    inflation rates in the countries in which the Company does business;

o    laws in various international jurisdictions that limit the right and
     ability of subsidiaries to pay dividends and remit earnings to affiliated
     companies unless specified conditions are met; and,

o    uncertainties arising from local business practices, cultural
     considerations and international political and trade tensions.

If the Company is unable to successfully manage the risks associated with its
global business, the Company's financial condition, cash flows and results of
operations may be negatively impacted.

The Company has operations in several countries in the Middle East, including
Bahrain, Egypt, Saudi Arabia, United Arab Emirates and Qatar, which are
geographically close to Iraq, Iran, Israel, Lebanon and other countries with a
continued high risk of armed hostilities. During 2006, 2005 and 2004, the
Company's Middle East operations contributed approximately $34.8 million, $32.7
million and $25.5 million, respectively, to the Company's operating income.
Additionally, the Company has operations in and sales to countries that have
encountered outbreaks of communicable diseases (e.g., Acquired Immune Deficiency
Syndrome (AIDS), avian influenza and others). Should such outbreaks worsen or
spread to other countries, the Company may be negatively impacted through
reduced sales to and within those countries and other countries impacted by such
diseases.

      EXCHANGE RATE FLUCTUATIONS MAY ADVERSELY IMPACT THE COMPANY'S BUSINESS.

Fluctuations in foreign exchange rates between the U.S. dollar and the
approximately 40 other currencies in which the Company conducts business may
adversely impact the Company's operating income and income from continuing
operations in any given fiscal period. Approximately 62% and 58% of the
Company's sales and approximately 71% and 67% of the Company's operating income
from continuing operations for the years ended December 31, 2006 and 2005,
respectively, were derived from operations outside the United States. More
specifically, during both 2006 and 2005, approximately 20% of the Company's
revenues were derived from operations in the U.K. Additionally, approximately
23% and 18% of the Company's revenues were derived from operations with the euro
as their functional

                                       -9-


currency during 2006 and 2005, respectively. Given the structure of the
Company's revenues and expenses, an increase in the value of the U.S. dollar
relative to the foreign currencies in which the Company earns its revenues
generally has a negative impact on operating income, whereas a decrease in the
value of the U.S. dollar tends to have the opposite effect. The Company's
principal foreign currency exposures are to the British pound sterling and the
euro. The Company's exposure to these currencies, as well as other foreign
currencies, has increased in 2006 due to the acquisitions of Hunnebeck and the
Northern Hemisphere mill services operations of Brambles Industrial Services
("BISNH") in the fourth quarter of 2005 and the acquisition of Cleton in the
third quarter of 2006.

Compared with the corresponding period in 2005, the average values of major
currencies changed as follows in relation to the U.S. dollar during 2006,
impacting the Company's sales and income:

      o     British pound sterling                    Strengthened by 2%
      o     euro                                      Strengthened by 2%
      o     South African rand                        Weakened by 6%
      o     Brazilian real                            Strengthened by 11%
      o     Canadian dollar                           Strengthened by 7%
      o     Australian dollar                         Neutral

Compared with exchange rates at December 31, 2005, the values of major
currencies changed as follows as of December 31, 2006:

      o     British pound sterling                    Strengthened by 14%
      o     euro                                      Strengthened by 12%
      o     South African rand                        Weakened by 10%
      o     Brazilian real                            Strengthened by 9%
      o     Canadian dollar                           Neutral
      o     Australian dollar                         Strengthened by 8%

The Company's foreign currency exposures increase the risk of income statement,
balance sheet and cash flow volatility. If the above currencies change
materially in relation to the U.S. dollar, the Company's financial position,
results of operations, or cash flows may be materially affected.

To illustrate the effect of foreign currency exchange rate changes in certain
key markets of the Company, in 2006, revenues would have been approximately 1%
or $35.3 million less and operating income would have been approximately 1% or
$3.0 million less if the average exchange rates for 2005 were utilized. A
similar comparison for 2005 would have decreased revenues approximately 1% or
$14.8 million, while operating income would have been approximately 1% or $2.8
million less if the average exchange rates for 2005 would have remained the same
as 2004. If the U.S. dollar weakens in relation to the euro and British pound
sterling, the Company would expect to see a positive impact on future sales and
income from continuing operations as a result of foreign currency translation.
Currency changes also result in assets and liabilities denominated in local
currencies being translated into U.S. dollars at different amounts than at the
prior period end.

The Company seeks to reduce exposures to foreign currency transaction
fluctuations through the use of forward exchange contracts. At December 31,
2006, the notional amount of these contracts was $170.9 million, and over 99% of
these contracts will mature within the first quarter of 2007. 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.

Although the Company engages in foreign currency forward exchange contracts and
other hedging strategies to mitigate foreign exchange risk, hedging strategies
may not be successful or may fail to offset the risk.

In addition, competitive conditions in the Company's manufacturing businesses
may limit the Company's ability to increase product prices in the face of
adverse currency movements. Sales of products manufactured in the United States
for the domestic and export markets may be affected by the value of the U.S.
dollar relative to other currencies. Any long-term strengthening of the U.S.
dollar could depress demand for these products and reduce sales and may cause
translation gains or losses due to the revaluation of accounts payable, accounts
receivable and other asset and liability accounts. Conversely, any long-term
weakening of the U.S. dollar could improve demand for these products and
increase sales and may cause translation gains or losses due to the revaluation
of accounts payable, accounts receivable and other asset and liability accounts.

                                      -10-


      NEGATIVE ECONOMIC CONDITIONS MAY ADVERSELY IMPACT THE ABILITY OF THE
      COMPANY'S CUSTOMERS TO MEET THEIR OBLIGATIONS TO THE COMPANY ON A TIMELY
      BASIS AND IMPACT THE VALUATION OF THE COMPANY'S ASSETS.

If a downturn in the economy occurs, it may adversely impact the ability of the
Company's customers to meet their obligations to the Company on a timely basis
and could result in bankruptcy filings by them. If customers are unable to meet
their obligations on a timely basis, it could adversely impact the realizability
of receivables, the valuation of inventories and the valuation of long-lived
assets across the Company's businesses, as well as negatively affect the
forecasts used in performing the Company's goodwill impairment testing under
SFAS No. 142, "Goodwill and Other Intangible Assets" ("SFAS 142"). If management
determines that goodwill or other assets are impaired or that inventories or
receivables cannot be realized at recorded amounts, the Company will be required
to record a write-down in the period of determination, which will reduce net
income for that period. Additionally, the risk remains that certain Mill
Services customers may file for bankruptcy protection, be acquired or
consolidate in the future, which could have an adverse impact on the Company's
income and cash flows. The potential financial impact of this risk has increased
with the Company's acquisition of BISNH in December 2005 and consolidation of
certain large steel mill customers in 2006. Conversely, such consolidation may
provide additional service opportunities for the Company.

      A NEGATIVE OUTCOME ON PERSONAL INJURY CLAIMS AGAINST THE COMPANY MAY
      ADVERSELY IMPACT RESULTS OF OPERATIONS AND FINANCIAL CONDITION.

The Company has been named as one of many defendants (approximately 90 or more
in most cases) in legal actions alleging personal injury from exposure to
airborne asbestos. In their suits, the plaintiffs have named as defendants many
manufacturers, distributors and repairers of numerous types of equipment or
products that may involve asbestos. Most of these complaints contain a standard
claim for damages of $20 million or $25 million against the named defendants. If
the Company was found to be liable in any of these actions and the liability was
to exceed the Company's insurance coverage, results of operations, cash flows
and financial condition could be adversely affected. For more information
concerning this litigation, see Note 10, Commitments and Contingencies, to the
Consolidated Financial Statements under Part II, Item 8, "Financial Statements
and Supplementary Data."

      THE COMPANY MAY LOSE CUSTOMERS OR BE REQUIRED TO REDUCE PRICES AS A RESULT
      OF COMPETITION.

The industries in which the Company operates are highly competitive.

o     The Company's Mill Services business is sustained mainly through contract
      renewals. Historically, the Company's contract renewal rate has averaged
      approximately 95%. If the Company is unable to renew its contracts at the
      historical rates or renewals are at reduced prices, revenue may decline.
o     The Company's Access Services business rents and sells equipment and
      provides erection and dismantling services to principally the
      non-residential and commercial construction and industrial plant
      maintenance markets. Contracts are awarded based upon the Company's
      engineering capabilities, product availability, safety record, and the
      ability to competitively price its rentals and services. If the Company is
      unable to consistently provide high-quality products and services at
      competitive prices, it may lose customers or operating margins may decline
      due to reduced selling prices.
o     The Company's manufacturing businesses compete with companies that
      manufacture similar products both internationally and domestically.
      Certain international competitors export their products into the United
      States and sell them at lower prices due to lower labor costs and
      government subsidies for exports. Such practices may limit the prices the
      Company can charge for its products and services. Additionally,
      unfavorable foreign exchange rates can adversely impact the Company's
      ability to match the prices charged by international competitors. If the
      Company is unable to match the prices charged by international
      competitors, it may lose customers.

The Company's strategy to overcome this competition includes continuous process
improvement and cost reduction programs, international customer focus and the
diversification, streamlining and consolidation of operations.

      INCREASED CUSTOMER CONCENTRATION AND CREDIT RISK IN THE MILL SERVICES
      SEGMENT MAY ADVERSELY IMPACT THE COMPANY'S FUTURE EARNINGS AND CASH FLOWS.

Concentrations of credit risk with respect to accounts receivable are generally
limited due to the Company's large number of customers and their dispersion
across different industries and geographies. However, the Company's Mill
Services Segment has several large customers throughout the world with
significant accounts receivable balances. In December 2005, the Company acquired
BISNH. This acquisition has increased the Company's corresponding concentration
of credit risk to customers in the steel industry. Additionally, further
consolidation in the global steel industry occurred in 2006 and additional
consolidation is probable. Should additional transactions occur involving some
of the steel industry's larger companies, which are customers of the Company, it
would result in an increase in

                                      -11-


concentration of credit risk for the Company. If a large customer were to
experience financial difficulty, or file for bankruptcy protection, it could
adversely impact the Company's income, cash flows and asset valuations. As part
of its credit risk management practices, the Company is developing strategies to
mitigate this increased concentration of credit risk.

      INCREASES IN ENERGY PRICES COULD INCREASE THE COMPANY'S OPERATING COSTS
      AND REDUCE ITS PROFITABILITY.

Worldwide political and economic conditions, an imbalance in the supply and
demand for oil, extreme weather conditions, or armed hostilities in
oil-producing regions, among other factors, may result in an increase in the
volatility of energy costs, both on a macro basis and for the Company
specifically. In 2006, 2005 and 2004, energy costs have approximated 4.0%, 3.6%
and 3.5% of the Company's revenue, respectively. To the extent that such costs
cannot be passed to customers in the future, operating income and results of
operations may be adversely affected.

      INCREASES OR DECREASES IN PURCHASE PRICES OR SELLING PRICES OR
      AVAILABILITY OF STEEL OR OTHER MATERIALS AND COMMODITIES MAY AFFECT THE
      COMPANY'S PROFITABILITY.

The profitability of the Company's manufactured products are affected by
changing purchase prices of steel and other materials and commodities. Beginning
in 2004, the price paid for steel and certain other commodities increased
significantly compared with prior years. Although these costs moderated in 2005,
such costs increased again during 2006 on a comparative basis with 2005. If raw
material costs associated with the Company's manufactured products increase and
the costs cannot be passed on to the Company's customers, operating income would
be adversely impacted. Additionally, decreased availability of steel or other
materials, such as carbon fiber used to manufacture filament-wound composite
cylinders, could affect the Company's ability to produce manufactured products
in a timely manner. If the Company cannot obtain the necessary raw materials for
its manufactured products, then revenues, operating income and cash flows will
be adversely affected. The Company acquired Excell Materials ("Excell") in
February 2007. Certain services performed by Excell result in the recovery,
processing and sale of stainless steel scrap to its customers. The selling price
of the scrap material is market-based and varies based upon the current fair
value of its components (predominantly nickel). Therefore, the revenue amounts
recorded from the sale of such scrap material vary based upon the fair value of
the commodity components being sold. The Company intends to execute hedging
instruments to help reduce the volatility of the revenue from the sale of the
scrap material at varying market prices. However, there can be no guarantee that
such hedging strategies will be fully effective in reducing the variability of
revenues from period to period.

      THE COMPANY IS SUBJECT TO VARIOUS ENVIRONMENTAL LAWS AND THE SUCCESS OF
      EXISTING OR FUTURE ENVIRONMENTAL CLAIMS AGAINST IT COULD ADVERSELY IMPACT
      THE COMPANY'S RESULTS OF OPERATIONS AND CASH FLOWS.

The Company's operations are subject to various federal, state, local and
international laws, regulations and ordinances relating to the protection of
health, safety and the environment, including those governing discharges to air
and water, handling and disposal practices for solid and hazardous wastes, the
remediation of contaminated sites and the maintenance of a safe work place.
These laws impose penalties, fines and other sanctions for non-compliance and
liability for response costs, property damages and personal injury resulting
from past and current spills, disposals or other releases of, or exposure to,
hazardous materials. The Company could incur substantial costs as a result of
non-compliance with or liability for remediation or other costs or damages under
these laws. The Company may be subject to more stringent environmental laws in
the future, and compliance with more stringent environmental requirements may
require the Company to make material expenditures or subject it to liabilities
that the Company currently does not anticipate.

The Company is currently 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
under the federal "Superfund" law. At several sites, the Company is currently
conducting environmental remediation, and it is probable that the Company will
agree to make payments toward funding certain other of these remediation
activities. It also is possible that some of these matters will be decided
unfavorably to the Company and that other sites requiring remediation will be
identified. Each of these matters is subject to various uncertainties and
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
Company has evaluated its potential liability and the Consolidated Balance
Sheets at December 31, 2006 and 2005 include an accrual of $3.8 million and $2.8
million, respectively, for environmental matters. The amounts charged against
pre-tax earnings related to environmental matters totaled $2.2 million, $1.5
million and $2.1 million for the years ended December 31, 2006, 2005 and 2004,
respectively. The liability for future remediation costs is evaluated on a
quarterly basis. Actual costs to be incurred at

                                      -12-


identified sites in future periods may be greater than the estimates, given
inherent uncertainties in evaluating environmental exposures.

      RESTRICTIONS IMPOSED BY THE COMPANY'S CREDIT FACILITIES AND OUTSTANDING
      NOTES MAY LIMIT THE COMPANY'S ABILITY TO OBTAIN ADDITIONAL FINANCING OR TO
      PURSUE BUSINESS OPPORTUNITIES.

The Company's credit facilities and certain notes payable agreements contain a
covenant requiring a maximum debt to capital ratio of 60%. In addition, certain
notes payable agreements also contain a covenant requiring a minimum net worth
of $475 million. These covenants limit the amount of debt the Company may incur,
which could limit its ability to obtain additional financing or pursue business
opportunities. In addition, the Company's ability to comply with these ratios
may be affected by events beyond its control. A breach of any of these covenants
or the inability to comply with the required financial ratios could result in a
default under these credit facilities. In the event of any default under these
credit facilities, the lenders under those facilities could elect to declare all
borrowings outstanding, together with accrued and unpaid interest and other
fees, to be due and payable, which would cause an event of default under the
notes. This could, in turn, trigger an event of default under the cross-default
provisions of the Company's other outstanding indebtedness. At December 31,
2006, the Company was in compliance with these covenants with a debt to capital
ratio of 48.1%, and a net worth of $1.15 billion. The Company had $395.3 million
in outstanding indebtedness containing these covenants at December 31, 2006.

      HIGHER THAN EXPECTED CLAIMS UNDER INSURANCE POLICIES, UNDER WHICH THE
      COMPANY RETAINS A PORTION OF THE RISK, COULD ADVERSELY IMPACT RESULTS OF
      OPERATIONS AND CASH FLOWS.

The Company retains a significant portion of the risk for property, workers'
compensation, U.K. employers' liability, automobile, general and product
liability losses. Reserves have been recorded which reflect the undiscounted
estimated liabilities for ultimate losses including claims incurred but not
reported. Inherent in these estimates are assumptions that are based on the
Company's history of claims and losses, a detailed analysis of existing claims
with respect to potential value, and current legal and legislative trends. At
December 31, 2006 and 2005, the Company had recorded liabilities of $103.4
million and $102.3 million, respectively, related to both asserted and
unasserted insurance claims. Included in the balance at December 31, 2006 and
2005 were $18.9 million and $25.2 million, respectively, of recognized
liabilities covered by insurance carriers. If actual claims are higher than
those projected by management, an increase to the Company's insurance reserves
may be required and would be recorded as a charge to income in the period the
need for the change was determined. Conversely, if actual claims are lower than
those projected by management, a decrease to the Company's insurance reserves
may be required and would be recorded as a reduction to expense in the period
the need for the change was determined.

      THE SEASONALITY OF THE COMPANY'S BUSINESS MAY CAUSE ITS QUARTERLY RESULTS
      TO FLUCTUATE.

The Company has historically generated the majority of its cash flows in the
third and fourth quarters (periods ending September 30 and December 31). This is
a direct result of normally higher sales and income during the second half of
the year, as the Company's business tends to follow seasonal patterns. If the
Company is unable to successfully manage the cash flow and other effects of
seasonality on the business, its results of operations may suffer. The Company's
historical revenue patterns and net cash provided by operating activities are
included in Part I, Item 1, "Business."

      THE COMPANY'S CASH FLOWS AND EARNINGS ARE SUBJECT TO CHANGES IN INTEREST
      RATES.

The Company's total debt as of December 31, 2006 was $1.06 billion. Of this
amount, approximately 47.7% had variable rates of interest and 52.3% had fixed
rates of interest. The weighted average interest rate of total debt was
approximately 5.7%. At current debt levels, a one-percentage increase/decrease
in variable interest rates would increase/decrease interest expense by
approximately $5.1 million per year.

The future financial impact on the Company associated with the above risks
cannot be estimated.

EXECUTIVE OVERVIEW
The Company's record performance in 2006 reflected the execution of the
Company's portfolio-based management strategy of growth through selective
strategic acquisitions and increased international diversity that is industrial
services focused. All of the Company's core operating groups showed improved
full-year results over the prior year. The 2006 results were led by the Access
Services and Mill Services Segments. Only the Gas Technologies Segment's results
were below prior year. In the first quarter of 2007, the Board of Directors
approved the divestiture of this business, which is expected to occur in the
second half of 2007.

The Company's 2006 revenues were a record $3.4 billion. This was an increase of
$657.1 million or 24% over 2005. Income from continuing operations was a record
$196.5 million for 2006 compared with $156.8 million in 2005, an increase of
25%. Diluted earnings per share from continuing operations were a record $4.65
for 2006, a 25% increase from 2005.

In addition to strong market conditions for most of the Company's services and
products, the 2006 performance benefited from the Company's November 21, 2005
acquisition of Hunnebeck Group GmbH ("Hunnebeck") and the December 29, 2005
acquisition of the Northern Hemisphere steel mill services of Brambles
Industrial Services ("BISNH"). Both of these acquisitions performed well in
2006. Revenues in 2006 were reduced by the sale of the Company's U.K.-based
Youngman manufacturing operation on October 1, 2005. The net effect of business
acquisitions and divestitures increased revenues by $405.2 million in 2006.

During 2006, the Company had record net cash provided by operating activities of
$409.2 million, a 30% increase over the $315.3 million achieved in 2005. The
Company expects strong cash flows from operating activities in 2007, exceeding
the record achieved in 2006. The Company's cash flows are further discussed in
the Liquidity and Capital Resources section.

The record revenue, income from continuing operations and diluted earnings per
share for 2006 demonstrate the balance and geographic diversity of the Company's
operations. The Company's Mill Services and Access Services Segments, as well as
the Engineered Products and Services ("all other") Category delivered improved
results. This operating balance and geographic diversity, as well as growth
opportunities in the Company's core services platforms, such as the February
2007 acquisition of Excell Materials, provide a broad foundation for future
growth and a hedge against normal changes in economic and industrial cycles.

                                      -19-


SEGMENT OVERVIEW
Mill Services Segment revenues in 2006 were $1.4 billion compared with $1.1
billion in 2005, a 29% increase. Operating income increased by 35% to $147.8
million, from $109.6 million in 2005. Operating margins for this Segment
increased by 50 basis points to 10.8% from 10.3% in 2005. The increase in
operating margins was due to improved operating performance at several
locations, principally due to the Company's ongoing cost reduction program. The
overall effect of acquisitions increased revenues for the Segment by $219.0
million in 2006, and BISNH was accretive in 2006. This Segment accounted for 40%
of the Company's revenues and 41% of the operating income for 2006.

The Access Services Segment's revenues in 2006 were $1,080.9 million compared
with $788.8 million in 2005, a 37% increase. Operating income increased by 61%
to $120.4 million, from $74.7 million in 2005. Operating margins for the Segment
improved by 160 basis points to 11.1% from 9.5% in 2005. These improvements were
broad-based, and were led by the North American and European operations,
including Hunnebeck. The net effect of business acquisitions and divestitures
increased revenues for this Segment by $186.2 million in 2006, mostly due to
Hunnebeck. This Segment accounted for 31% of the Company's revenues and 34% of
the operating income for 2006.

The Engineered Products and Services ("all other") Category's revenues in 2006
were $578.2 million compared with $546.9 million in 2005, a 6% increase.
Operating income increased by 11% to $77.5 million, from $69.7 million in 2005.
Four of the five businesses in this Category contributed higher revenues in 2006
compared with 2005, and three of the businesses contributed higher operating
income. The air-cooled heat exchangers business continued to benefit from strong
energy market demand due to increased natural gas drilling and transmission. The
industrial grating business again posted improved results due to strong
end-markets in energy and non-residential construction. The roofing granules and
abrasives business and the boiler and process equipment business contributed
solid performances in 2006, consistent with 2005. The railway track maintenance
services and equipment business continued the shift towards contract services,
but operating income was negatively impacted by increased operating expenses,
mostly from the effects of a rail grinder accident, increased raw material costs
and higher sub-contractor equipment and labor costs. However, the overall strong
performance by the businesses in this group helped to moderate the rising
commodity costs experienced throughout this Category in 2006. This Category
accounted for 17% of the Company's revenue and 21% of the operating income for
2006.

The Gas Technologies Segment's revenues in 2006 were $397.7 million compared
with $370.2 million in 2005, a 7% increase. Operating income decreased by 21% to
$14.2 million, from $17.9 million in 2005. Operating income was negatively
impacted by restructuring costs associated with strategic initiatives including
exiting an underperforming product line, as well as higher commodity costs for
brass and steel. These increased costs reduced operating margins for this
Segment by 120 basis points from 4.8% in 2005 to 3.6% in 2006. This Segment
accounted for 12% of the Company's revenues and 4% of the operating income for
2006.

The positive effect of foreign currency translation increased 2006 consolidated
revenues by $35.3 million and pre-tax income by $2.4 million when compared with
2005.

OUTLOOK OVERVIEW
The Company's operations span several industries and products as more fully
discussed in Part I, Item 1, "Business." On a macro basis, the Company is
affected by worldwide steel mill production and capacity utilization;
non-residential and commercial construction and industrial maintenance
activities; industrial production volume; and the general business trend towards
the outsourcing of services. The overall outlook for 2007 continues to be
positive for these business drivers.

The Company's Mill Services Segment expects to continue to benefit from
consistent levels of global steel production at mills served by the Company, new
contract signings and continued accretion from the December 2005 acquisition of
BISNH. However, the Company may also experience increased operating costs that
could have a negative impact on operating margins, to the extent these costs
cannot be passed to customers.

Both the domestic and international Access Services activity remains strong.
Although the sale of the Youngman light-access manufacturing business in late
2005 modestly affected 2006 revenues, operating income in 2006 for the Segment
was a record and is expected to continue to benefit from the strong performance
of Hunnebeck; increased non-residential construction spending and industrial
maintenance activity in the Company's major markets; continued development of
new markets; further market penetration from new products; product cross-selling
opportunities among the markets served by the three Access Services businesses;
and cost reduction opportunities through consolidated procurement and continuous
process improvement initiatives.

                                      -20-


The outlook for the Engineered Products and Services ("all other") Category
remains positive for 2007. Income and margins in the Company's railway track
maintenance services and equipment business are expected to improve in the long
term from the shift towards contract services. The air-cooled heat exchangers
business is expected to continue to benefit from strong end-market demand due to
increased natural gas drilling and transmission. The boiler and process
equipment business and the industrial grating products business are expected to
post another year of solid, stable results in 2007. The roofing granules and
abrasives business is expected to continue to perform consistently well
long-term, although increased operating costs could reduce operating margins.

In January 2007, the Company announced its intention to divest the Gas
Technologies business. This decision is consistent with the Company's overall
strategic focus on global industrial services businesses. The divestiture is
expected to be completed in the second half of 2007.

The stable or improved market conditions for most of the Company's services and
products, the significant investments made recently for acquisitions, such as
the February 2007 acquisition of Excell Materials, and other growth-related
capital expenditures provide the base for achieving the Company's stated
objective for growth in diluted earnings per share from continuing operations
and net cash provided by operating activities for 2007. The record performance
and cash flow achieved in 2006 and the executed strategic actions provide a
solid foundation towards achieving these goals.

2006 HIGHLIGHTS
The following significant items affected the Company overall during 2006 in
comparison with 2005:

Company Wide:
o     Strong worldwide economic activity, as well as the accretive performance
      of the Hunnebeck and BISNH acquisitions, benefited the Company in 2006.
      This included increased access equipment services, especially in North
      America and Europe; net increased volume and new business in the Mill
      Services Segment; and increased demand for air-cooled heat exchangers and
      industrial grating products.
o     As expected, during 2006, the Company experienced higher fuel and
      energy-related costs, as well as higher commodity costs for certain
      manufacturing businesses. To the extent that such costs cannot be passed
      to customers in the future, operating income may be adversely affected.
o     Total pension expense for 2006 increased $5.8 million compared with 2005.
      Defined contribution and multi-employer plan expenses for 2006 increased
      approximately $7.4 million from 2005 due to increased volume in the Mill
      Services and Access Services Segments. This was partially offset by
      decreased defined benefit pension expense of approximately $1.6 million
      due principally to improved returns on plan assets in 2005 as well as the
      Company's cash contributions to the plans' assets. The Company is
      currently taking additional actions designed to further mitigate pension
      expense volatility. This is more fully discussed in the Outlook, Trends
      and Strategies section.
o     During 2006, international sales and operating income were 62% and 71%,
      respectively, of total sales and operating income. This compares with 2005
      levels of 58% of sales and 67% of operating income. The international
      percentages have increased from 2005 to 2006 principally as a result of
      the Hunnebeck and BISNH acquisitions.

     ===========================================================================

     MILL SERVICES SEGMENT - SIGNIFICANT EFFECTS ON OPERATING INCOME:

     o    Operating income for 2006 increased by $35.3 million (excluding the
          effect of foreign currency translation), as a result of the BISNH
          acquisition and increased volumes and net new business, particularly
          in the United States, Europe and Latin America, partially offset by
          increased operating costs (as noted below).
     o    Compared with 2005, the Segment's operating income and margins in 2006
          were negatively impacted by increased fuel and energy-related costs
          (excluding increased costs due to acquisitions) of approximately $10
          million. A portion of this increase was growth-related. Despite the
          increased energy costs, margins improved in 2006 due to continuous
          process improvement activities and stringent cost controls.
     o    Foreign currency translation in 2006 increased operating income for
          this Segment by $2.8 million, compared with 2005.

     ===========================================================================

     ACCESS SERVICES SEGMENT - SIGNIFICANT EFFECTS ON OPERATING INCOME:

     o    The net effect of acquisitions and divestitures had a positive effect
          on 2006 operating income of $25.8 million, with the Hunnebeck business
          performing well.
     o    In 2006, there was a continued strengthening in the North American
          non-residential construction markets that started in the latter half
          of 2004. This had a positive effect on volume (particularly equipment
          rentals) which caused overall margins and operating income in North
          America to improve. Equipment rentals, particularly in the
          construction sector, provide the highest margins for this Segment.

                                      -22-


     o    The international access services business continued to improve due to
          increased non-residential construction spending and industrial
          maintenance activity in the Company's major markets.
     o    Operating income and margins were negatively impacted in 2006 due to
          lower gains on the sale of significant assets in 2006 of $2.5 million,
          compared with asset gains of $5.1 million in 2005.
     o    Foreign currency translation in 2006 increased operating income for
          this Segment by $1.5 million compared with 2005.

     ===========================================================================

     ENGINEERED PRODUCTS AND SERVICES ("ALL OTHER") CATEGORY - SIGNIFICANT
     EFFECTS ON OPERATING INCOME:

     o    Operating income for the air-cooled heat exchangers business improved
          in 2006 due to increased volume resulting from an improved natural gas
          market.
     o    The boiler and process equipment business delivered improved results
          in 2006 due to increased revenues from the new-generation MACH
          boilers, Thermific boilers and process equipment.
     o    The increase in 2006 operating income for the industrial grating
          products business was due principally to higher pricing and an
          improved product mix, partially offset by higher raw material costs.
     o    Higher pricing resulting from the pass-through of higher energy costs
          for roofing granules and abrasives again sustained profitable results
          for that business in 2006, approximating 2005's operating income.
     o    Operating income for the railway track maintenance services and
          equipment business was lower in 2006 compared with 2005 due to
          increased operating expenses, mostly from the effects of a rail
          grinder accident, increased raw material costs and higher
          sub-contractor equipment and labor costs, partially offset by
          favorable equipment sales mix and increased repair parts volume.
     o    The impact of foreign currency translation in 2006 did not have a
          material impact on operating income for this Category when compared
          with the 2005.

     GAS TECHNOLOGIES SEGMENT - SIGNIFICANT IMPACTS ON OPERATING INCOME:

     o    Operational improvements and the effect of increased sales were offset
          by increased brass costs, higher insurance and restructuring costs
          (principally in the third quarter) associated with strategic
          initiatives in the valves business in 2006 compared with 2005. A
          strategic action plan has been implemented to improve the results of
          the valves business. Cost savings as a result of this plan helped
          decrease the impact of significantly increased brass costs in 2006. In
          addition, certain product lines have been rationalized which resulted
          in significant restructuring costs incurred in 2006.
     o    The international businesses, principally in Europe, contributed to
          the improved performance of the cryogenics business during 2006
          compared with 2005.
     o    Despite higher demand for industrial cylinders, operating income
          decreased from 2005 due mainly to the effect of equipment repairs and
          maintenance, product mix and higher commodity and energy-related
          costs.
     o    Operating income decreased for propane tanks in 2006, due to decreased
          demand, as well as increased commodity costs. The negative effect of
          these items was partially offset by a favorable product mix and
          process improvement initiatives.
     o    Operating income increased during 2006 for composite-wrapped cylinders
          due to increased sales and a favorable product mix, partially offset
          by higher raw material costs.
     o    Foreign currency translation in 2006 decreased operating income for
          this Segment by $0.9 million.

OUTLOOK, TRENDS AND STRATEGIES
Looking to 2007 and beyond, the following significant items, trends and
strategies are expected to affect the Company:

Company Wide:
-------------
 o    The Company will continue its focus on expanding the industrial services
      businesses, with a particular emphasis on growing the Mill Services
      Segment, the Access Services Segment and other specialized services.
      Growth is expected to be achieved through the provision of additional
      services to existing customers, new contracts in both developed and
      emerging markets and strategic acquisitions, such as the February 2007
      acquisition of Excell Materials, Inc. Additionally, new higher-margin
      service opportunities in railway services will be pursued globally.
o     In January 2007, the Company announced its intention to divest the Gas
      Technologies business. This decision is consistent with the Company's
      overall strategic focus on industrial services businesses.
o     The Company will continue to invest in strategic acquisitions and growth
      capital investments; however, management will be very selective in its
      capital investments, choosing those with the highest Economic Value Added
      (EVA(R)).
o     A greater focus on corporate-wide expansion into emerging economies is
      expected in the coming years. More specifically, within the next three to
      five years, a focused strategy of the Company is to approximately double
      its presence in the Latin American, Asia Pacific, Middle East and Africa,
      and Eastern European markets to approximately 30% of total revenues.
o     The continued growth of the Chinese steel industry, as well as other Asian
      emerging economies, could impact the Company in several ways. Increased
      steel mill production in China, and in other Asian countries, may provide
      additional service opportunities for the Mill Services Segment. However,
      increased Asian steel exports could result in lower steel production in
      other parts of the world, affecting the Company's customer base.
      Additionally, continued increased Chinese economic activity may result in
      increased commodity costs in the future, which may adversely affect the
      Company's manufacturing businesses. The potential impact of these risks is
      currently unknown.
o     Increases in energy and commodity costs (e.g., fuel, natural gas, steel,
      brass, aluminum, etc.) and worldwide demand for these commodities could
      have an adverse effect on the Company's raw material costs and ability to
      obtain the necessary raw materials. Fuel and energy costs increased
      approximately $15 million in 2006 compared

                                      -24-


      with 2005 (excluding increased costs due to acquisitions). A portion of
      this increase was growth-related. Should cost increases continue, it could
      result in reduced operating income for certain products to the extent that
      such costs cannot be passed on to customers. The effect of any Middle East
      armed hostilities on the cost of fuel and commodities is currently
      unknown, but it could have a significant effect.
o     The armed hostilities in the Middle East could also have a significant
      effect on the Company's operations in the region. The potential impact of
      this risk is currently unknown. This exposure is further discussed in Part
      I, Item 1A, "Risk Factors."
o     Foreign currency translation had an overall favorable effect on the
      Company's sales, operating income and Stockholders' equity as a result of
      translation adjustments during 2006. If the U.S. dollar strengthens,
      particularly in relationship to the euro or British pound sterling, the
      impact on the Company would generally be negative in terms of reduced
      sales, income and Stockholders' equity.
o     The Company expects strong cash flow from operating activities in 2007
      exceeding the record of $409 million achieved in 2006. This will help
      support the Company's growth initiatives.
o     Controllable cost reductions and continuous process improvement
      initiatives across the Company are targeted to further enhance margins for
      most businesses. These initiatives include improved supply-chain
      management; additional outsourcing in the manufacturing businesses; and an
      added emphasis on corporate-wide procurement initiatives. The Company will
      use its increased size and leverage due to recent acquisitions to reduce
      vendor costs and focus on additional opportunities for cost reductions via
      procurement in low-cost countries such as China and India.
o     Total pension expense (defined benefit, defined contribution and
      multi-employer) for 2007 is expected to approximate or be slightly higher
      than the 2006 level. Defined benefit pension expense is expected to
      decline in 2007 due to the significant level of cash contributions,
      including voluntary cash contributions (approximately $10.6 million during
      2006 and $16.9 million during 2005, mostly to the U.K. plan, which will
      have a positive effect on future years' pension expense), to the defined
      benefit pension plans as well as the higher than expected returns in 2006
      on the plans' assets. The Company's pension task force continues to
      evaluate alternative strategies to further mitigate overall pension
      expense, including the on-going evaluation of investment fund managers'
      performance; the balancing of plan assets and liabilities; the risk
      assessment of all multi-employer pension plans; the possible merger of
      certain plans; the consideration of incremental cash contributions to
      certain plans; and other changes that should mitigate future volatility
      and expense. On a comparative basis, total pension expense during 2006 was
      $5.8 million higher than 2005, due principally to increased defined
      contribution and multi-employer pension expense resulting from increased
      volume in the Access Services and Mill Services Segments.
o     Changes in worldwide interest rates, particularly in the U.S. and Europe,
      could have a significant effect on the Company's overall interest expense,
      as approximately 48% of the Company's borrowings are at variable interest
      rates as of December 31, 2006 (in comparison to approximately 50% at
      December 31, 2005). The Company manages the mix of fixed rate and floating
      rate debt to preserve adequate funding flexibility as well as control the
      effect of interest rate changes on consolidated interest expense.

Mill Services Segment:
----------------------
o     To maintain pricing levels, a more disciplined steel industry has been
      adjusting production levels to bring inventories in-line with current
      demand. Based on current market conditions and industry reports, the
      Company expects global steel production to remain stable in 2007, which
      would generally have a favorable effect on this Segment's revenues.
o     Further consolidation in the global steel industry is probable. Should
      additional transactions occur involving some of the steel industry's
      larger companies that are customers of the Company, it would result in an
      increase in concentration of revenues and credit risk for the Company. If
      a large customer were to experience financial difficulty, or file for
      bankruptcy protection, it could adversely impact the Company's income,
      cash flows and asset valuations. As part of its credit risk management
      practices, the Company closely monitors the credit standing and accounts
      receivable position of its customer base. Further consolidation may also
      increase pricing pressure on the Company and the competitive risk of
      services contracts which are up for renewal. Conversely, such
      consolidation may provide additional service opportunities for the Company
      as the Company believes it is well-positioned competitively.
o     Energy-related costs increased approximately $10 million during 2006
      compared with 2005 (excluding increased costs due to acquisitions). Some
      of these costs were passed on to customers in the form of selling price
      increases. Given the volatility of such costs, the future effect on the
      Company cannot be quantified.
o     The Company has been placing significant emphasis on improving operating
      margins of this Segment. Margin improvements are most likely to be
      achieved through internal efforts such as global procurement initiatives;
      process improvement programs; maintenance best practices programs; and
      continued execution of the Company's reorganization plan.

                                      -25-


Access Services Segment:
------------------------
o     Both the international and domestic Access Services businesses experienced
      buoyant markets during 2006 and that is expected to continue in 2007.
      Specifically, international and especially North American non-residential
      construction activity continues at historically high volume levels.
      Additionally, new product line additions continue to benefit growth in
      North America.

Engineered Products and Services ("all other") Category:
--------------------------------------------------------
o     International demand for the railway track maintenance services and
      equipment business's products and services is expected to be strong in the
      long term. In addition, increased volume of higher-margin contract
      services and manufacturing process improvements and efficiencies are
      expected to improve margins on a long-term basis. Additionally,
      higher-margin international equipment sales will continue to be pursued by
      this business.
o     Worldwide supply and demand for steel could have an adverse impact on raw
      material costs and the ability to obtain the necessary raw materials for
      most businesses in this Category. The Company has implemented certain
      strategies and plans to help ensure continued product supply to our
      customers and mitigate the potentially negative impact that rising steel
      prices could have on operating income.
o     The roofing granules and abrasives business is expected to continue to
      perform well long-term, although increased energy costs could reduce
      operating margins. This business is pursuing the use of more
      energy-efficient equipment to help mitigate the increased energy-related
      costs.
o     Due to a strong natural gas market and additional North American
      opportunities, demand for air-cooled heat exchangers is expected to remain
      strong for 2007.

Gas Technologies Segment:
-------------------------
o     In January 2007, the Company announced its intention to divest the Gas
      Technologies business. This decision is consistent with the Company's
      overall strategic focus on industrial services businesses.

      26.3     Net increased revenues in the Gas Technologies Segment due
               principally to demand for cryogenics equipment, certain valves
               and industrial cylinders, partially offset by decreased demand
               for propane tanks.

       8.4     Increased revenues of the industrial grating products business
               due to increased demand and, to a lesser extent, increased prices
               and a more favorable product mix.

     (17.0)    Net decreased revenues in the railway track maintenance services
               and equipment business due to decreased equipment sales,
               partially offset by increased contract services as well as repair
               part sales in the U.K. Equipment sales declined due to a large
               order shipped to China in 2005 which did not recur in 2006.

  IN MILLIONS                  CHANGE IN REVENUES 2005 VS. 2004
--------------------------------------------------------------------------------
$     72.5     Net increased revenues in the Access Services Segment due
               principally to improved markets in the North America and the
               strength of the international business, particularly in the
               Middle East and Europe (excluding the net effect of acquisitions
               and divestitures).

      41.9     Net increased volume, new contracts and price changes in the Mill
               Services Segment (excluding acquisitions).

      38.0     Net increased revenues in the railway track maintenance services
               and equipment business due to increased contract services
               (principally in the U.K.), rail equipment sales (primarily to
               international customers) and repair part sales.

      32.2     Increased revenues of the air-cooled heat exchangers business due
               to an improved natural gas market.

      31.0     Net increased revenues in the Gas Technologies Segment due
               principally to improved market conditions for industrial
               cylinders, cryogenics equipment and composite-wrapped cylinders,
               partially offset by slightly decreased demand for propane tanks.
               The decrease in propane tank sales was due to customers
               accelerating purchases in 2004 to avoid anticipated price
               increases due to commodity cost inflation.

      16.5     Net effect of business acquisitions and divestitures. Increased
               revenues of $4.0 million and $12.5 million in the Mill Services
               and Access Services Segments, respectively.

      14.8     Effect of foreign currency translation.

      12.4     Increased revenues of the industrial grating products business
               due to increased demand (partially due to the effects of

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

2006 vs. 2005
-------------
Selling, general and administrative ("SG&A") expenses for 2006 increased $114.2
million or 29% from 2005, a higher rate than the 24% increase in revenues. The
higher relative percentage increase in SG&A expense as compared with revenues
was due principally to the effect of certain acquisitions which, by their
nature, have a higher percentage of SG&A-related costs. This increase was
attributable to the following significant items:

               decrease was attributable principally to $5.5 million in net
               gains that were realized in 2006 from the sale of non-core assets
               compared with $9.7 million in 2005. The net gains for both years
               were principally within the Access Services and Mill Services
               Segments.

       3.9     Increase in impaired asset write-downs due principally to exiting

--------------------------------------------------------------------------------

INTEREST EXPENSE

2006 vs. 2005
-------------
Interest expense in 2006 was $18.6 million or 44% higher than in 2005. This was
principally due to increased borrowings to finance business acquisitions made in
the fourth quarter of 2005 and, to a lesser extent, higher interest rates on
variable interest rate borrowings. The impact of foreign currency translation
also increased interest expense by approximately $0.6 million.

2005 vs. 2004
-------------
Interest expense in 2005 was $0.9 million or 2% higher than in 2004. This was
principally due to higher interest rates on variable interest rate borrowings in
the United States and, to a lesser extent, increased borrowings in November and
December 2005 to finance acquisitions. This was partially offset by
approximately $0.3 million of decreased interest expense due to the effect of
foreign currency translation.

--------------------------------------------------------------------------------

INCOME TAX EXPENSE FROM CONTINUING OPERATIONS

2006 vs. 2005
-------------
The increase in 2006 of $32.8 million or 51% in the provision for income taxes
from continuing operations was primarily due to increased earnings from
continuing operations for the reasons mentioned above and an increased effective
income tax rate. The effective income tax rate relating to continuing operations
for 2006 was 32.3% versus 28.1% for 2005. The increase related principally to
increased effective income tax rates on international earnings and remittances.
The year 2005 included a one-time benefit recorded in the fourth quarter of $2.7
million associated with funds repatriated under the American Jobs Creation Act
of 2004 (AJCA). Additionally, during the fourth quarter of 2005, consistent with
the Company's strategic plan of investing for growth at certain international
locations, the Company received a one-time income tax benefit of $3.6 million.

2005 vs. 2004
-------------
The increase in 2005 of $15.7 million or 32% in the provision for income taxes
from continuing operations was primarily due to increased earnings from
continuing operations for the reasons mentioned above, partially offset by a
decreased effective income tax rate. The effective income tax rate relating to
continuing operations for 2005 was 28.1% versus 28.6% for 2004. The decrease
related principally to reduced effective income tax rates on international
earnings and remittances, partially offset by reduced favorable settlements of
tax contingencies in comparison with 2004. The differences on international
earnings and remittances from 2004 to 2005 included a one-time benefit recorded
in the fourth quarter of 2005 of $2.7 million associated with funds repatriated
under the American Jobs Creation Act of 2004 (AJCA). Additionally, during the
fourth quarter of 2005, consistent with the Company's strategic plan of
investing for growth at certain international locations, the Company received a
one-time income tax benefit of $3.6 million.

Financial Statements under Part II, Item 8, "Financial Statements and

--------------------------------------------------------------------------------

INCOME FROM CONTINUING OPERATIONS

2006 vs. 2005
-------------
Income from continuing operations in 2006 of $196.5 million was $39.8 million or
25% higher than 2005. This increase resulted from strong demand for most of the
Company's services and products and the net effect of business acquisitions and
divestitures.

2005 vs. 2004
-------------
Income from continuing operations in 2005 of $156.8 million was $43.2 million or
38% higher than 2004. This increase resulted from strong demand for most of the
Company's services and products (principally from the Access Services Segment
and industrial grating products) that resulted in increased revenues, as well as
from stringent cost controls and process improvements that contained selling,
general and administrative expenses growth to a level below revenue growth.

--------------------------------------------------------------------------------

INCOME FROM DISCONTINUED OPERATIONS

2006 vs. 2005
-------------
Income from discontinued operations for 2006 approximated the 2005 amount and
was immaterial.

2005 vs. 2004
-------------
Income from discontinued operations for 2005 decreased $7.8 million or 101% from
2004. This decrease was attributable principally to after-tax income from the
one-time settlement of the Company's Federal Excise Tax (FET) litigation in
2004. For additional information on the FET litigation see Note 10, Commitments
and Contingencies, to the Consolidated Financial Statements under Part II, Item
8, "Financial Statements and Supplementary Data," in the Company's 2004 Form
10-K.

--------------------------------------------------------------------------------

NET INCOME AND EARNINGS PER SHARE

2006 vs. 2005
Net income of $196.4 million and diluted earnings per share of $4.65 in 2006
exceeded 2005 by $39.7 million or 25% and $0.93 or 25%, respectively, due to
increased income from continuing operations for the reasons described above.

2005 vs. 2004
Net income of $156.7 million and diluted earnings per share of $3.72 in 2005
exceeded 2004 by $35.4 million or 29% and $0.81 or 28%, respectively, primarily
due to increased income from continuing operations, partially offset by the
decrease in income from discontinued operations for the reasons described above.

LIQUIDITY AND CAPITAL RESOURCES

OVERVIEW
Building on its history of strong operating cash flows, the Company achieved a
record $409.2 million in operating cash flow in 2006. This represents a 30%
improvement over 2005's operating cash flow of $315.3 million. In 2006, this
significant source of cash has enabled the Company to invest $340.2 million in
capital expenditures (45% of which were for revenue-growth projects); pay $54.5
million in stockholder dividends; and invest $34.3 million in business
acquisitions. These significant 2006 investments follow $290 million of capital
expenditures (over 50% of which were for revenues-growth projects); $49.9
million in stockholder dividends; and $394.5 million in business acquisitions
invested in 2005. The Company believes these investments provide a solid
foundation for future revenue and Economic Value Added (EVA(R)) growth.

Despite significant investment amounts in 2006, the Company's net cash
borrowings decreased by $35.7 million. Balance sheet debt, which is affected by
foreign currency translation, increased $53.1 million from December 31, 2005.
However, for the same period, the debt to capital ratio declined from 50.4% to
48.1% as a result of increased Stockholder's Equity.

                                      -31-


The Company's strategic objectives for 2007 include generating record net cash
provided by operating activities in excess of the $409.2 million generated in
2006. The Company's strategy to redeploy excess or discretionary cash in
long-term, high-renewal-rate services contracts for the Mill Services business;
for growth and international diversification in the Access Services Segment; for
growth and international expansion of the recently acquired Excell Materials;
expansion of the railway track maintenance services and equipment business; and
for sensible bolt-on acquisitions in the industrial services businesses. The
Company also foresees continuing its long and consistent history of paying
dividends to stockholders and to pay down debt to the extent possible.

To further enhance its portfolio of industrial services businesses and provide
cash flow for strategic investments, in January 2007, the Company's Board of
Directors approved a plan to divest the Gas Technologies Segment. The Company
estimates that the business will be sold during the second half of 2007.
Proceeds from the sale of this manufacturing business will provide financial
flexibility to further invest in the Company's services businesses and for debt
reduction.

The Company also intends to focus on improved working capital management.
Specifically, accounts receivable in the Access Services Segment and inventory
levels in the manufacturing businesses will continue to be scrutinized and
challenged to improve the Company's use of funds.

SOURCES AND USES OF CASH
The Company's principal sources of liquidity are cash from operations and
borrowings under its various credit agreements, augmented periodically by cash
proceeds from asset sales. The primary drivers of the Company's cash flow from
operations are the Company's sales and income, particularly in the services
businesses. The Company's long-term Mill Services contracts provide predictable
cash flows for several years into the future. (See "Certainty of Cash Flows"
section for additional information on estimated future revenues of Mill Services
contracts and order backlogs for the Company's manufacturing businesses and
railway track maintenance services and equipment business). Cash returns on
capital investments made in prior years, for which no cash is currently
required, are a significant source of operating cash. Depreciation expense
related to these investments is a non-cash charge. The Company also continues to
maintain working capital at a manageable level based upon the requirements and
seasonality of the business.

Major uses of operating cash flows and borrowed funds include payroll costs and
related benefits; pension funding payments; raw material purchases for the
manufacturing businesses; income tax payments; interest payments; insurance
premiums and payments of self-insured casualty losses; and machinery, equipment,
automobile and facility rental payments. Other primary uses of cash include
capital investments, principally in the industrial services businesses; debt
principal payments; and dividend payments. Cash will also be used for strategic
or bolt-on acquisitions as the appropriate opportunities arise.

      RESOURCES AVAILABLE FOR CASH REQUIREMENTS - The Company has various credit

-------------------------------------------------------------------------------

The Company's euro-based commercial paper program has not been rated since the
euro market does not require it. In August 2006, S&P reaffirmed it's A- and A-2
ratings for the Company's long-term notes and U.S. commercial paper,
respectively, and its stable outlook. In January 2007, Fitch reaffirmed it's
ratings for the Company's long-term notes and U.S. commercial paper,
respectively, and its stable outlook. Also in January 2007, Moody's reaffirmed
its ratings for the Company. A downgrade to the Company's credit ratings would
probably increase borrowing costs to the Company, while an improvement in the
Company's credit ratings would probably decrease borrowing costs to the Company.

CURRENT RATIO                                1.4:1          1.5:1
================================================================================

Working capital decreased 9% in 2006 due principally to the following factors:

o    Cash decreased by $19.7 million due principally to payments made to reduce
     the Company's net cash borrowings.

o    Net receivables increased by $86.9 million due principally to increases in
     the Mill Services and Access Services Segments which were largely due to
     foreign currency translation as a result of the strengthening of the
     British pound sterling and the euro in relation to the U.S. dollar, higher
     sales and the Cleton acquisition. Partially offsetting these increases was
     the timing of cash collections in the railway track maintenance services
     and equipment business.

o    The increase in inventory balances related principally to increased demand
     in the Access Services Segment, increased demand and the timing of
     purchases and shipments in the Gas Technologies Segment and foreign
     currency translation.

o    Notes payable and current maturities increased $94.2 million principally
     due to increased bank overdrafts and the anticipated payment of a portion
     of commercial paper borrowings within one year.

o    Accounts payable increased $39.8 million due principally to increases in
     the Mill Services and Access Services Segments which were largely due to
     foreign currency translation, the Cleton acquisition and the timing of
     payments.

CERTAINTY OF CASH FLOWS - The certainty of the Company's future cash flows is
underpinned by the long-term nature of the Company's mill services contracts. At
December 31, 2006, the Company's mill services contracts had estimated future
revenues of $4.4 billion, compared with $4.3 billion as of December 31, 2005. In
addition, as of December 31, 2006, the Company had an order backlog of $301.0
million for its manufacturing businesses and railway track maintenance services
and equipment business. This compares with $275.8 million as of December 31,
2005. This increase is due principally to new orders for air-cooled heat
exchangers, industrial grating and increased demand for certain products within
the Gas Technologies Segment, partially offset by decreased orders for railway
track maintenance services in the Engineered Products and Services ("all other")
Category. The railway track maintenance services and equipment business backlog
includes a significant portion that is long-term, which will not be realized
until 2007 and later due to the long lead times necessary to build certain
equipment, and the long-term nature of certain service contracts. Order backlog
for scaffolding, shoring and forming services of the Access Services Segment and
for roofing granules and slag abrasives is excluded from the above amounts.
These amounts are generally not

                                      -35-


quantifiable due to short order lead times for certain services, the nature and
timing of the products and services provided and equipment rentals with the
ultimate length of the rental period often unknown.

The types of products and services that the Company provides are not subject to
rapid technological change, which increases the stability of related cash flows.
Additionally, each of the Company's businesses is among the top three companies
(relative to sales) in the industries and markets the Company serves. Due to
these factors, the Company is confident in its future ability to generate
positive cash flows from operations.

CASH FLOW SUMMARY
The Company's cash flows from operating, investing and financing activities, as
reflected in the Consolidated Statements of Cash Flows, are summarized in the
following table:

   Net change in cash and cash equivalents    $  (19.7)   $   26.8    $    13.9
================================================================================

      CASH FROM OPERATING ACTIVITIES - Net cash provided by operating activities
in 2006 was a record $409.2 million, an increase of $93.9 million from 2005. The
increased cash from operations in 2006 resulted from the following factors:

o    Increased net income in 2006 compared with 2005.

o    The timing of accounts receivable collections at the railway track
     maintenance services and equipment business, mill services business and the
     air-cooled heat exchangers business.

o    Partially offsetting the above improvements was the use of cash for other
     assets and liabilities in 2006 compared with a source of cash for other
     assets and liabilities for 2005. This was principally due to an increase in
     insurance liabilities during 2005 not repeated in 2006, partially offset by
     an increase in income tax payments due to increased net income in 2006. The
     increased insurance liabilities during 2005 were directly offset by
     increased third-party insurance claim receivables.

      CASH USED IN INVESTING ACTIVITIES - Capital investments in 2006 were
$340.2 million, an increase of $50.0 million from 2005. Approximately 45% of the
investments were for projects intended to grow future revenues. Investments were
made predominantly for the industrial services businesses with 48% in the Mill
Services Segment and 41% in the Access Services Segment. The Company also
invested $34.3 million principally for acquisitions in the Mill Services and
Access Services Segments. See Note 2, Acquisitions and Dispositions, to the
Consolidated Financial Statements under Part II, Item 8, "Financial Statements
and Supplementary Data," for additional disclosures related to these
acquisitions.

      CASH USED IN FINANCING ACTIVITIES - The following table summarizes the
Company's debt and capital positions as of December 31, 2006 and 2005.

                                      -36-


The Company's debt as a percentage of total capital decreased in 2006. Overall
debt increased due to increases in foreign currency-denominated debt due to
foreign currency translation resulting from the weakening of the U.S. dollar in
comparison with the euro and the British pound sterling. Additionally, total
equity increased due principally to increased net income in 2006 and foreign
currency translation, partially offset by SFAS No. 158, "Employers' Accounting
for Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB
Statements No. 87, 88, 106 and 132(R)" ("SFAS 158") pension adjustments and
dividends.

DEBT COVENANTS
The Company's credit facilities and certain notes payable agreements contain
covenants requiring a minimum net worth of $475 million and a maximum debt to
capital ratio of 60%. Based on balances at December 31, 2006, the Company could
increase borrowings by approximately $655.2 million and still be within its debt
covenants. Alternatively, keeping all other factors constant, the Company's
equity could decrease by approximately $438.0 million and the Company would
still be within its covenants. Additionally, the Company's 7.25% British pound
sterling-denominated notes due October 27, 2010 include a covenant that permits
the note holders to redeem their notes, at par, in the event of a change of
control of the Company. The Company expects to be compliant with these debt
covenants one year from now.

CASH AND VALUE-BASED MANAGEMENT
The Company plans to continue with its strategy of selective investing for
strategic purposes for the foreseeable future. An example of the execution of
this strategy is the February 2007 acquisition of Excell Materials. The goal of
this strategy is to improve the Company's Economic Value Added (EVA(R)) under
the program that commenced January 1, 2002. Under this program the Company
evaluates strategic investments based upon the investment's economic profit. EVA
equals after-tax operating profits less a charge for the use of the capital
employed to create those profits (only the service cost portion of pension
expense is included for EVA purposes). Therefore, value is created when a
project or initiative produces a return above the cost of capital. Consistent
with the 2006 results, meaningful improvement in EVA was achieved compared with
2005.

The Company is committed to continue paying dividends to stockholders. The
Company has increased the dividend rate for 13 consecutive years, and in
November 2006, the Company paid its 226th consecutive quarterly cash dividend.
In November 2006, the Company declared its 227th consecutive quarterly dividend
and increased its dividend rate by more than nine percent. The Company also
plans to continue paying down debt to the extent possible. Additionally, the
Company has authorization to repurchase up to one million of its shares through
January 31, 2008.

The Company's financial position and debt capacity should enable it to meet
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
well-positioned and intends to continue investing strategically in high-return
projects and acquisitions, reducing debt, to the extent possible, and paying
cash dividends as a means to enhance stockholder value.

APPLICATION OF CRITICAL ACCOUNTING POLICIES
The Company's discussion and analysis of its financial condition and results of
operations are based upon the consolidated financial statements, which have been
prepared in accordance with accounting principles generally accepted in the
United States. The preparation of these financial statements requires the
Company to make estimates and judgments that affect the reported amounts of
assets, liabilities, revenues and expenses and related disclosure of contingent
liabilities. On an on-going basis the Company evaluates its estimates, including
those related to pensions and other postretirement benefits, bad debts, goodwill
valuation, long-lived asset valuations, inventory valuations, insurance
reserves, contingencies and income taxes. The impact of changes in these
estimates, as necessary, is reflected in the respective segment's operating
income in the period of the change. The Company bases its estimates on
historical experience and on various other assumptions that are believed to be
reasonable under the circumstances, the results of which form the basis for
making judgments about the carrying values of assets and liabilities that are
not readily apparent from other sources. Actual results may differ from these
estimates under different outcomes, assumptions or conditions.

The Company believes the following critical accounting policies are affected by
its more significant judgments and estimates used in the preparation of its
consolidated financial statements. Management has discussed the development and
selection of the critical accounting estimates described below with the Audit
Committee of the Board of Directors and the Audit Committee has reviewed the
Company's disclosure relating to these estimates in this Management's Discussion
and Analysis of Financial Condition and Results of Operations. These items
should be read in conjunction with Note 1, Summary of Significant Accounting
Policies, to the Consolidated Financial Statements under Part II, Item 8,
"Financial Statements and Supplementary Data."

                                      -37-


PENSION BENEFITS
The Company has defined benefit pension plans in several countries. The largest
of these plans are in the United Kingdom and the United States. The Company's
funding policy for these plans is to contribute amounts sufficient to meet the
minimum funding pursuant to U.K. and U.S. statutory requirements, plus any
additional amounts that the Company may determine to be appropriate. The Company
made cash contributions to its defined benefit pension plans of $37.2 million
(including $10.6 million of discretionary payments) and $48.8 million (including
$16.9 million discretionary payments) during 2006 and 2005, respectively.
Additionally, the Company expects to make a minimum of $25.6 million in cash
contributions to its defined benefit pension plans during 2007.

For the year 2005, the Company accounted for its defined benefit pension plans
in accordance with SFAS No. 87, "Employer's Accounting for Pensions" ("SFAS
87"), which requires that amounts recognized in financial statements be
determined on an actuarial basis. At December 31, 2005, the adjustment to
recognize the additional minimum liability required under SFAS 87 impacted
accumulated other comprehensive loss in the Stockholders' Equity section of the
Consolidated Balance Sheets by $14.7 million, net of deferred income taxes.

As of December 31, 2006, the Company accounted for its defined benefit pension
plans in accordance with SFAS 158, which requires the Company to recognize in
its balance sheet, the overfunded or underfunded status of its defined benefit
postretirement plans measured as the difference between the fair value of the
plan assets and the benefit obligation (projected benefit obligation for a
pension plan) as an asset or liability. The charge or credit is recorded as
adjustment to accumulated other comprehensive income/loss, net of tax. This
reduced the Company's equity on an after-tax basis by approximately $88.2
million compared with measurement under prior standards. The results of
operations were not affected. The adoption of SFAS 158 did not have a negative
impact on compliance with the Company's debt covenants.

Management implemented a three-part strategy in 2002 and 2003 to deal with the
adverse market forces that have increased the unfunded benefit obligations of
the Company. These strategies included pension plan design changes, a review of
funding policy alternatives and a review of the asset allocation policy and
investment manager structure. With regards to plan design, the Company amended a
majority of the U.S. defined benefit pension plans and certain international
defined benefit pension plans so that accrued service is no longer granted for
periods after December 31, 2003, although compensation increases will continue
to be recognized on actual service to-date (for the U.S. plans this is limited
to 10 years - through December 2013). In place of these plans, the Company
established, effective January 1, 2004, defined contribution pension plans
providing for the Company to contribute a specified matching amount for
participating employees' contributions to the plan. Domestically, this match is
made on employee contributions up to four percent of their eligible
compensation. Additionally, the Company may provide a discretionary contribution
of up to two percent of compensation for eligible employees. Internationally,
this match is up to six percent of eligible compensation with an additional two
percent going towards insurance and administrative costs. The Company believes
these new retirement benefit plans will provide a more predictable and less
volatile pension expense than existed under the defined benefit plans.

The Company's pension task force continues to evaluate alternative strategies to
further reduce overall pension expense including the on-going evaluation of
investment fund managers' performance; the balancing of plan assets and
liabilities; the risk assessment of all multi-employer pension plans; the
possible merger of certain plans; the consideration of incremental cash
contributions to certain plans; and other changes that could reduce future
pension expense volatility and minimize risk.

      CRITICAL ESTIMATE - DEFINED BENEFIT PENSION BENEFITS

Accounting for defined benefit pensions and other postretirement benefits
requires the use of actuarial assumptions. The principal assumptions used
include the discount rate and the expected long-term rate-of-return on plan
assets. Each assumption is reviewed annually and represents management's best
estimate at that time. The assumptions are selected to represent the average
expected experience over time and may differ in any one year from actual
experience due to changes in capital markets and the overall economy. These
differences will impact the amount of unfunded benefit obligation and the
expense recognized.

The discount rates as of the September 30, 2006 measurement date for the U.K.
defined benefit pension plan and the October 31, 2006 measurement date for the
U.S. defined benefit pension plans were 5.13% and 5.87%, respectively. These
rates were used in calculating the Company's projected benefit obligations as of
December 31, 2006. The discount rates selected represent the average yield on
high-quality corporate bonds as of the measurement dates. The global
weighted-average of these assumed discount rates for the years ending December
31, 2006, 2005 and 2004 were 5.3%, 5.3% and 5.7%, respectively. Annual pension
expense is determined using the discount rate as of

                                      -38-


the beginning of the year, which for 2007 is the 5.3% global weighted-average
discount rate. Pension expense and the projected benefit obligation generally
increase as the selected discount rate decreases.

The expected long-term rate-of-return on plan assets is determined by evaluating
the portfolios' asset class return expectations with the Company's advisors as
well as actual, long-term, historical results of asset returns for the pension
plans. The pension expense increases as the expected long-term rate-of-return on
assets decreases. For 2006, the global weighted-average expected long-term
rate-of-return on asset assumption was 7.6%. For 2007, the expected global
long-term rate-of-return on assets will remain the same at 7.6%. This rate was
determined based on a model of expected asset returns for an actively managed
portfolio.

Based on the updated actuarial assumptions and the structural changes in the
pension plans mentioned previously, the Company's 2007 pension expense is
expected to stabilize. Total pension expense increased from 2005 to 2006 by $5.8
million due principally to increased multi-employer and defined contribution
pension plan costs resulting from increased volume in the Access Services and
Mill Services Segments. From 2004 to 2005, pension expense decreased by $1.7
million due principally to lower defined benefit pension expense in the United
Kingdom. This resulted from plan design changes in 2004 when certain defined
benefit plans were replaced by defined contribution plans.

Changes in pension benefit expense may occur in the future due to changes in
actuarial assumptions and due to changes in returns on plan assets resulting
from financial market conditions. Holding all other assumptions constant, a
one-half percent increase or decrease in the discount rate and the expected
long-term rate-of-return on plan assets would increase or decrease annual 2007
pre-tax defined benefit pension expense as follows:

Should circumstances change that affect these estimates, changes (either
increases or decreases) to the net pension obligations may be required and would
be recorded in accordance with the provisions of SFAS 87 and SFAS 158.
Additionally, certain events could result in the pension obligation changing at
a time other than the annual measurement date. This would occur when the benefit
plan is amended or when plan curtailments occur under the provisions of SFAS No.
88, "Employers' Accounting for Settlements and Curtailments of Defined Benefit
Pension Plans and for Termination Benefits" ("SFAS 88").

See Note 8, Employee Benefit Plans, to the Consolidated Financial Statements
under Part II, Item 8, "Financial Statements and Supplementary Data," for
additional disclosures related to these items.

NOTES AND ACCOUNTS RECEIVABLE
Notes and accounts receivable are stated at their net realizable value through
the use of an allowance for doubtful accounts. The allowance is maintained for
estimated losses resulting from the inability or unwillingness of customers to
make required payments. The Company has policies and procedures in place
requiring customers to be evaluated for creditworthiness prior to the execution
of new service contracts or shipments of products. These reviews are structured
to minimize the Company's risk related to realizability of its receivables.
Despite these policies and procedures, the Company may still experience
collection problems and potential bad debts due to economic conditions within
certain industries (e.g., construction and steel industries) and countries and
regions in which the Company operates. As of December 31, 2006 and 2005,
receivables of $753.2 million and $666.3 million, respectively, were net of
reserves of $25.4 million and $24.4 million, respectively.

      CRITICAL ESTIMATE - NOTES AND ACCOUNTS RECEIVABLE

A considerable amount of judgment is required to assess the realizability of
receivables, including the current creditworthiness of each customer, related
aging of the past due balances and the facts and circumstances

                                      -39-


surrounding any non-payment. The Company's provisions for bad debts during 2006,
2005 and 2004 were $9.2 million, $6.5 million and $5.0 million, respectively.
The increase from 2005 to 2006 related principally to the acquisition of
businesses in the fourth quarter of 2005 and overall increased revenues.

On a monthly basis, customer accounts are analyzed for collectibility. Reserves
are established based upon a specific-identification method as well as
historical collection experience, as appropriate. The Company also evaluates
specific accounts when it becomes aware of a situation in which a customer may
not be able to meet its financial obligations due to a deterioration in its
financial condition, credit ratings or bankruptcy. The reserve requirements are
based on the facts available to the Company and are re-evaluated and adjusted as
additional information is received. Reserves are also determined by using
percentages (based upon experience) applied to certain aged receivable
categories. Specific issues are discussed with Corporate Management and any
significant changes in reserve amounts or the write-off of balances must be
approved by a specifically designated Corporate Officer. All approved items are
monitored to ensure they are recorded in the proper period. Additionally, any
significant changes in reserve balances are reviewed to ensure the proper
Corporate approval has occurred.

If the financial condition of the Company's customers were to deteriorate,
resulting in an impairment of their ability to make payments, additional
allowances may be required. Conversely, an improvement in a customer's ability
to make payments could result in a decrease of the allowance for doubtful
accounts. Changes in the allowance related to both of these situations would be
recorded through income in the period the change was determined.

The Company has not materially changed its methodology for calculating
allowances for doubtful accounts for the years presented.

See Note 3, Accounts Receivable and Inventories, to the Consolidated Financial
Statements under Part II, Item 8, "Financial Statements and Supplementary Data,"
for additional disclosures related to these items.

GOODWILL
The Company's net goodwill balances were $612.5 million and $559.6 million, as
of December 31, 2006 and 2005, respectively. Goodwill is not amortized but
tested for impairment at the reporting unit level on an annual basis, and
between annual tests whenever events or circumstances indicate that the carrying
value of a reporting unit's goodwill may exceed its fair value.

      CRITICAL ESTIMATE - GOODWILL

A discounted cash flow model is used to estimate the fair value of a reporting
unit. This model requires the use of long-term planning estimates and
assumptions regarding industry-specific economic conditions that are outside the
control of the Company. The annual test for impairment includes the selection of
an appropriate discount rate to value cash flow information. The basis of this
discount rate calculation is derived from several internal and external factors.
These factors include, but are not limited to, the average market price of the
Company's stock, the number of shares of stock outstanding, the book value of
the Company's debt, a long-term risk-free interest rate, and both market and
size-specific risk premiums. The Company's annual goodwill impairment testing,
performed as of October 1, 2006 and 2005, indicated that the fair value of all
reporting units tested exceeded their respective book values and therefore no
additional goodwill impairment testing was required. Due to uncertain market
conditions, it is possible that estimates used for goodwill impairment testing
may change in the future. Therefore, there can be no assurance that future
goodwill impairment tests will not result in a charge to earnings.

The Company has not materially changed its methodology for goodwill impairment
testing for the years presented. There are currently no known trends, demands,
commitments, events or uncertainties that are reasonably likely to occur that
would materially affect the methodology or assumptions described above.

See Note 5, Goodwill and Other Intangible Assets, to the Consolidated Financial
Statements under Part II, Item 8, "Financial Statements and Supplementary Data,"
for additional information on goodwill and other intangible assets.

ASSET IMPAIRMENT
Long-lived assets are reviewed for impairment when events and circumstances
indicate that the book value of an asset may be impaired. The amounts charged
against pre-tax income related to impaired long-lived assets were $4.4 million,
$0.6 million and $0.4 million in 2006, 2005 and 2004, respectively. The
increased 2006 amount relates to exiting an underperforming product line of the
Gas Technologies Segment.

                                      -40-


      CRITICAL ESTIMATE - ASSET IMPAIRMENT

The determination of a long-lived asset impairment loss involves significant
judgments based upon short and long-term projections of future asset
performance. Impairment loss estimates are based upon the difference between the
book value and the fair value of the asset. The fair value is generally based
upon the Company's estimate of the amount that the assets could be bought or
sold for in a current transaction between willing parties. If quoted market
prices for the asset or similar assets are unavailable, the fair value estimate
is generally calculated using a discounted cash flow model. Should circumstances
change that affect these estimates, additional impairment charges may be
required and would be recorded through income in the period the change was
determined.

The Company has not materially changed its methodology for calculating asset
impairments for the years presented. There are currently no known trends,
demands, commitments, events or uncertainties that are reasonably likely to
occur that would materially affect the methodology or assumptions described
above.

INVENTORIES
Inventories are stated at the lower of cost or market. Inventory balances are
adjusted for estimated obsolete or unmarketable inventory equal to the
difference between the cost of inventory and its estimated market value. At
December 31, 2006 and 2005, inventories of $285.2 million and $251.1 million,
respectively, are net of lower of cost or market reserves and obsolescence
reserves of $14.3 million and $16.1 million, respectively.

      CRITICAL ESTIMATE - INVENTORIES

In assessing the ultimate realization of inventory balance amounts, the Company
is required to make judgments as to future demand requirements and compare these
with the current or committed inventory levels. If actual market conditions are
determined to be less favorable than those projected by management, additional
inventory write-downs may be required and would be recorded through income in
the period the determination is made. Additionally, the Company records reserves
to adjust a substantial portion of its U.S. inventory balances to the last-in,
first-out (LIFO) method of inventory valuation. In adjusting these reserves
throughout the year, the Company estimates its year-end inventory costs and
quantities. At December 31 of each year, the reserves are adjusted to reflect
actual year-end inventory costs and quantities. During periods of inflation, the
LIFO expense usually increases and during periods of deflation it decreases.
These year-end adjustments resulted in pre-tax income/(expense) of $(2.1)
million, $1.7 million and $(4.3) million in 2006, 2005 and 2004, respectively.

The Company has not materially changed its methodology for calculating inventory
reserves for the years presented. There are currently no known trends, demands,
commitments, events or uncertainties that are reasonably likely to occur that
would materially affect the methodology or assumptions described above.

See Note 3, Accounts Receivable and Inventories, to the Consolidated Financial
Statements under Part II, Item 8, "Financial Statements and Supplementary Data,"
for additional disclosures related to these items.

INSURANCE RESERVES
The Company retains a significant portion of the risk for property, workers'
compensation, U.K. employers' liability, automobile, general and product
liability losses. At December 31, 2006 and 2005 the Company has recorded
liabilities of $103.4 million and $102.3 million, respectively, related to both
asserted as well as unasserted insurance claims. At December 31, 2006 and 2005,
$18.9 million and $25.2 million, respectively, is included in insurance
liabilities related to claims covered by insurance carriers for which a
corresponding receivable has been recorded.

      CRITICAL ESTIMATE - INSURANCE RESERVES

Reserves have been recorded based upon actuarial calculations which reflect the
undiscounted estimated liabilities for ultimate losses including claims incurred
but not reported. Inherent in these estimates are assumptions which are based on
the Company's history of claims and losses, a detailed analysis of existing
claims with respect to potential value, and current legal and legislative
trends. If actual claims differ from those projected by management, changes
(either increases or decreases) to insurance reserves may be required and would
be recorded through income in the period the change was determined. During 2006,
the Company recorded a retrospective insurance reserve adjustment that increased
pre-tax insurance expense by $1.2 million. In 2005 and 2004, the retrospective
insurance reserve adjustments decreased pre-tax insurance expense for
self-insured programs by $4.1 million and $2.7 million, respectively. The
Company has programs in place to improve claims experience, such as aggressive
claim and insured litigation management and an improved focus on workplace
safety.

                                      -41-


The Company has not materially changed its methodology for calculating insurance
reserves for the years presented. There are currently no known trends, demands,
commitments, events or uncertainties that are reasonably likely to occur that
would materially affect the methodology or assumptions described above.

LEGAL AND OTHER CONTINGENCIES
Reserves for contingent liabilities are recorded when it is probable that an
asset has been impaired or a liability has been incurred and the loss can be
reasonably estimated. Adjustments to estimated amounts are recorded as necessary
based on new information or the occurrence of new events or the resolution of an
uncertainty. Such adjustments are recorded in the period that the required
change is identified.

      CRITICAL ESTIMATE - LEGAL AND OTHER CONTINGENCIES

On a quarterly basis, recorded contingent liabilities are analyzed to determine
if any adjustments are required. Additionally, functional department heads
within each business unit are consulted monthly to ensure all issues with a
potential financial accounting impact, including possible reserves for
contingent liabilities have been properly identified, addressed or disposed of.
Specific issues are discussed with Corporate Management and any significant
changes in reserve amounts or the adjustment or write-off of previously recorded
balances must be approved by a specifically designated Corporate Officer. If
necessary, outside legal counsel, other third parties or internal experts are
consulted to assess the likelihood and range of outcomes for a particular issue.
All approved changes in reserve amounts are monitored to ensure they are
recorded in the proper period. Additionally, any significant changes in reported
business unit reserve balances are reviewed to ensure the proper Corporate
approval has occurred. On a quarterly basis, the Company's business units submit
a reserve listing to the Corporate headquarters which is reviewed in detail. All
significant reserve balances are discussed with a designated Corporate Officer
to assess their validity, accuracy and completeness. Anticipated changes in
reserves are identified for follow-up prior to the end of a reporting period.
Any new issues that may require a reserve are also identified and discussed to
ensure proper disposition. Additionally, on a quarterly basis, all significant
environmental reserve balances or issues are evaluated to assess their validity,
accuracy and completeness.

The Company has not materially changed its methodology for calculating legal and
other contingencies for the years presented. There are currently no known
trends, demands, commitments, events or uncertainties that are reasonably likely
to occur that would materially affect the methodology or assumptions described
above.

See Note 10, Commitments and Contingencies, to the Consolidated Financial
Statements under Part II, Item 8, "Financial Statements and Supplementary Data,"
for additional disclosure on this uncertainty and other contingencies.

INCOME TAXES
The Company is subject to various federal, state and local income taxes in the
taxing jurisdictions where the Company operates. At the end of each quarterly
period, the Company makes its best estimate of the annual effective income tax
rate and applies that rate to year-to-date pre-tax income to arrive at the
year-to-date income tax provision. Income tax loss contingencies are recorded in
the period when it is determined that it is probable that a liability has been
incurred and the loss can be reasonably estimated. Adjustments to estimated
amounts are recorded as necessary based upon new information, the occurrence of
new events or the resolution of an uncertainty. As of December 31, 2006, 2005
and 2004, the Company's net effective income tax rate was 32.3%, 28.1% and
29.1%, respectively.

A valuation allowance to reduce deferred tax assets is evaluated on a quarterly
basis. The valuation allowance is principally for tax-loss carryforwards which
are uncertain as to realizability. The valuation allowance was $13.9 million and
$21.7 million as of December 31, 2006 and 2005, respectively.

      CRITICAL ESTIMATE - INCOME TAXES

The annual effective income tax rates are developed giving recognition to tax
rates, tax holidays, tax credits and capital losses, as well as certain exempt
income and non-deductible expenses in all of the jurisdictions where the Company
does business. The income tax provision for the quarterly period is the change
in the year-to-date provision from the previous quarterly period.

The Company considers future taxable income and ongoing prudent and feasible tax
planning strategies in assessing the need for the valuation allowance. In the
event the Company were to determine that it would more likely than not be able
to realize its deferred tax assets in the future in excess of its net recorded
amount, an adjustment to the deferred tax asset would increase income in the
period such determination was made. Likewise, should the Company

                                      -42-


determine that it would not be able to realize all or part of its net deferred
tax assets in the future, an adjustment to the deferred tax assets would
decrease income in the period in which such determination was made.

The Company has not materially changed its methodology for calculating income
tax expense for the years presented.

In July 2006, the FASB issued FASB Interpretation, ("FIN") 48, "Accounting for
Uncertainty in Income Taxes-an interpretation of FASB Statement No. 109" ("FIN
48"), which clarifies the accounting for uncertainty in income taxes recognized
in an entity's financial statements in accordance with SFAS No. 109, "Accounting
for Income Taxes." It prescribes a recognition threshold and measurement
attribute for financial statement recognition and disclosure of tax positions
taken or expected to be taken on a tax return. This interpretation is effective
for fiscal years beginning after December 15, 2006. The Company will adopt this
interpretation in the first quarter of 2007.

The Company is currently evaluating the requirements of FIN 48 and has not yet
determined the impact on the consolidated financial statements. There are
currently no other known trends, demands, commitments, events or uncertainties
that are reasonably likely to occur that would materially affect the methodology
or assumptions described above.

See Note 9, Income Taxes, to the Consolidated Financial Statements under Part
II, Item 8, "Financial Statements and Supplementary Data," for additional
disclosures related to these items.

RESEARCH AND DEVELOPMENT
The Company invested $3.0 million, $2.7 million and $2.6 million in internal
research and development programs in 2006, 2005 and 2004, respectively. Internal
funding for research and development was as follows:

==============================================================================

BACKLOG
As of December 31, 2006, the Company's order backlog, exclusive of long-term
mill services contracts, access services and roofing granules and slag
abrasives, was $301.0 million compared with $275.8 million as of December 31,
2005, a 9% increase. Of the $301.0 million of order backlog at December 31,
2006, approximately $58.7 million or 20% is not expected to be filled in 2007.

                                                              ORDER BACKLOG

      Consolidated Backlog                                $  301.0    $  275.8
===============================================================================

Order backlog for the Engineered Products and Services ("all other") Category at
December 31, 2006 was 3% above the December 31, 2005 order backlog. The change
is principally due to increased order backlog of air-cooled heat exchangers and
industrial grating products, partially offset by decreased order backlog for
railway track maintenance services. Order backlog for roofing granules and slag
abrasives is excluded from the above amounts. Order backlog amounts for that
product group are generally not quantifiable due to the short order lead times
of the products provided.

                                      -43-


The Gas Technologies Segment order backlog at December 31, 2006 was 43% above
the December 31, 2005 order backlog. The change primarily reflects increased
order backlog for cryogenics equipment and industrial gas cylinders, partially
offset by decreased order backlog for composite pressure vessels.

Mill services contracts have an estimated future value of $4.4 billion at
December 31, 2006 compared with $4.3 billion at December 31, 2005. Approximately
60% of these revenues are expected to be recognized by December 31, 2009. The
remaining revenues are expected to be recognized between January 1, 2010 and
December 31, 2015.

Order backlog for scaffolding, shoring and forming services of the Access
Services Segment is excluded from the above amounts. These amounts are generally
not quantifiable due to short order lead times for certain services, the nature
and timing of the products and services provided and equipment rentals with the
ultimate length of the rental period often unknown.

DIVIDEND ACTION
The Company paid four quarterly cash dividends of $0.325 per share in 2006, for
an annual rate of $1.30. This is an increase of 8.3% from 2005. At the November
2006 meeting, the Board of Directors increased the dividend by 9.2% to an annual
rate of $1.42 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 February 2007 payment marked the 227th consecutive quarterly dividend paid
at the same or at an increased rate. In 2006, 28% of net earnings were paid out
in dividends. The Company is philosophically committed to maintaining or
increasing the dividend at a sustainable level. The Company has paid dividends
each year since 1939.

                  MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER
                               FINANCIAL REPORTING

Management of Harsco Corporation, together with its consolidated subsidiaries
(the Company), is responsible for establishing and maintaining adequate internal
control over financial reporting. The Company's internal control over financial
reporting is a process designed under the supervision of the Company's principal
executive and principal financial officers to provide reasonable assurance
regarding the reliability of financial reporting and the preparation of the
Company's financial statements for external reporting purposes in accordance
with U.S. generally accepted accounting principles.

The Company's internal control over financial reporting includes policies and
procedures that:

o     Pertain to the maintenance of records that, in reasonable detail,
      accurately and fairly reflect transactions and dispositions of assets of
      the Company;

o     Provide reasonable assurance that transactions are recorded as necessary
      to permit preparation of financial statements in accordance with U.S.
      generally accepted accounting principles, and that receipts and
      expenditures of the Company are being made only in accordance with
      authorizations of management and the directors of the Company; and

o     Provide reasonable assurance regarding prevention or timely detection of
      unauthorized acquisition, use or disposition of the Company's assets that
      could have a material effect on the Company's financial statements.

Because of its inherent limitations, internal control over financial reporting
may not prevent or detect misstatements. Also, projections of any evaluation of
effectiveness to future periods are subject to the risk that controls may become
inadequate because of changes in conditions, or that the degree of compliance
with the policies and procedures may deteriorate.

Management has assessed the effectiveness of its internal control over financial
reporting as of December 31, 2006 based on the framework established in INTERNAL
CONTROL -- INTEGRATED FRAMEWORK issued by the Committee of Sponsoring
Organizations of the Treadway Commission (COSO). Based on this assessment,
management has determined that the Company's internal control over financial
reporting is effective as of December 31, 2006.

Management's assessment of the effectiveness of the Company's internal control
over financial reporting as of December 31, 2006 has been audited by
PricewaterhouseCoopers LLP, an independent registered public accounting firm, as
stated in their report appearing below, which expresses unqualified opinions on
management's assessment and on the effectiveness of the Company's internal
control over financial reporting as of December 31, 2006.

             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

PricewaterhouseCoopers LLP

To The Stockholders of Harsco Corporation:

We have completed integrated audits of Harsco Corporation's consolidated
financial statements and of its internal control over financial reporting as of
December 31, 2006, in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Our opinions, based on our audits,
are presented below.

Consolidated financial statements and financial statement schedule

In our opinion, the consolidated financial statements listed in the accompanying
index present fairly, in all material respects, the financial position of Harsco
Corporation and its subsidiaries at December 31, 2006 and 2005, and the results
of their operations and their cash flows for each of the three years in the
period ended December 31, 2006 in conformity with accounting principles
generally accepted in the United States of America. In addition, in our opinion,
the financial statement schedule listed in the index appearing under Item 15(a)2
presents fairly, in all material respects, the information set forth therein
when read in conjunction with the related consolidated financial statements.
These financial statements and financial statement schedule are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements and financial statement schedule based on
our audits. We conducted our audits of these statements in accordance with the
standards of the Public Company Accounting Oversight Board (United States).
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit of financial statements 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 our opinion.

Internal control over financial reporting
-----------------------------------------

Also, in our opinion, management's assessment, included in the accompanying
"Management's Report on Internal Control Over Financial Reporting," that the
Company maintained effective internal control over financial reporting as of
December 31, 2006 based on criteria established in INTERNAL CONTROL - INTEGRATED
FRAMEWORK issued by the Committee of Sponsoring Organizations of the Treadway
Commission (COSO), is fairly stated, in all material respects, based on those
criteria. Furthermore, in our opinion, the Company maintained, in all material
respects, effective internal control over financial reporting as of December 31,
2006, based on criteria established in INTERNAL CONTROL - INTEGRATED FRAMEWORK
issued by the COSO. The Company's management is responsible for maintaining
effective internal control over financial reporting and for its assessment of
the effectiveness of internal control over financial reporting. Our
responsibility is to express opinions on management's assessment and on the
effectiveness of the Company's internal control over financial reporting based
on our audit. We conducted our audit of internal control over financial
reporting in accordance with the standards of the Public Company Accounting
Oversight Board (United States). Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether effective
internal control over financial reporting was maintained in all material
respects. An audit of internal control over financial reporting includes
obtaining an understanding of internal control over financial reporting,
evaluating management's assessment, testing and evaluating the design and
operating effectiveness of internal control, and performing such other
procedures as we consider necessary in the circumstances. We believe that our
audit provides a reasonable basis for our opinions.

A company's internal control over financial reporting is a process designed to
provide reasonable assurance regarding the reliability of financial reporting
and the preparation of financial statements for external purposes in accordance
with generally accepted accounting principles. A company's internal control over
financial reporting includes those policies and procedures that (i) pertain to
the maintenance of records that, in reasonable detail, accurately and fairly
reflect the transactions and dispositions of the assets of the company; (ii)
provide reasonable assurance that transactions are recorded as necessary to
permit preparation of financial statements in accordance with generally accepted
accounting principles, and that receipts and expenditures of the company are
being made only in accordance with authorizations

                                      -47-


of management and directors of the company; and (iii) provide reasonable
assurance regarding prevention or timely detection of unauthorized acquisition,
use, or disposition of the company's assets that could have a material effect on
the financial statements.

Because of its inherent limitations, internal control over financial reporting
may not prevent or detect misstatements. Also, projections of any evaluation of
effectiveness to future periods are subject to the risk that controls may become
inadequate because of changes in conditions, or that the degree of compliance
with the policies or procedures may deteriorate.

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 (the "Company"). Additionally, the Company
consolidates three entities in which it has an equity interest of 49% to 50% and
exercises management control. These three entities had combined revenues of
approximately $87.3 million or 2.5% of the Company's total revenues in 2006.
Investments in unconsolidated entities (all of which are 40-50% owned) are
accounted for under the equity method. The Company does not have any off-balance
sheet arrangements with unconsolidated special-purpose entities.

RECLASSIFICATIONS
Certain reclassifications have been made to prior years' amounts to conform with
current year classifications. These reclassifications relate principally to
components of the Consolidated Balance Sheets.

As a result of these reclassifications, certain prior year amounts presented for
comparative purposes will not individually agree with previously filed Forms
10-K or 10-Q.

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, 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 of by sale
are not depreciated while they are held for sale.

LEASES
The Company leases certain property and equipment under noncancelable lease
agreements. All lease agreements are evaluated and classified as either an
operating lease or capital lease. A lease is classified as a capital lease if
any of the following criteria are met: transfer of ownership to the Company by
the end of the lease term; the lease contains a bargain purchase option; the
lease term is equal to or greater than 75% of the asset's economic life; or the
present value of future minimum lease payments is equal to or greater than 90%
of the asset's fair market value. Operating lease expense is recognized ratably
over the entire lease term, including rent abatement periods and rent holidays.

GOODWILL AND OTHER INTANGIBLE ASSETS
Goodwill is not amortized but tested for impairment at the reporting unit level.
SFAS No. 142, "Goodwill and Other Intangible Assets," (SFAS 142) defines a
reporting unit as an operating segment or one level below an operating segment
(referred to as a component). A component of an operating segment is a reporting
unit if the component constitutes a business for which discrete financial
information is available and segment management regularly reviews the operating
results of that component. Accordingly, the Company performs the goodwill
impairment test at the operating segment level for the Mill Services Segment,
the Access Services Segment and the Engineered Products and Services category
and at the component level for the Gas Technologies Segment. The goodwill
impairment tests are performed on an annual basis as of October 1 and between
annual tests whenever events or circumstances indicate that the carrying value
of a reporting unit's goodwill may exceed its fair value. A discounted cash flow
model is used to estimate the fair value of a reporting unit. This model
requires the use of long-term planning forecasts and assumptions regarding
industry-specific economic conditions that are outside the control of the
Company. See Note 5, "Goodwill and Other Intangible Assets," for additional
information on intangible assets and goodwill impairment testing. Finite-lived
intangible assets are amortized over their estimated useful lives.

IMPAIRMENT OF LONG-LIVED ASSETS (OTHER THAN GOODWILL)
Long-lived assets 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

                                      -54-


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 of are reported at the lower of the carrying
amount or fair value less cost to sell.

REVENUE RECOGNITION
Product sales and service sales are recognized when they are realized or
realizable and when earned. Revenue is realized or realizable and earned when
all of the following criteria are met: persuasive evidence of an arrangement
exists, delivery has occurred or services have been rendered, the Company's
price to the buyer is fixed or determinable and collectibility is reasonably
assured. Service sales include sales of the Mill Services and Access Services
Segments as well as railway track maintenance services. Product sales include
sales of the Gas Technologies Segment as well as the manufacturing businesses of
the Engineered Products and Services ("all other") Category.

      MILL SERVICES SEGMENT - This Segment provides services predominantly on a
long-term, volume-of-production contract basis. Contracts may include both fixed
monthly fees as well as variable fees based upon specific services provided to
the customer. The fixed-fee portion is recognized periodically as earned
(normally monthly) over the contractual period. The variable-fee portion is
recognized as services are performed and differs from period-to-period based
upon the actual provision of services.

      ACCESS SERVICES SEGMENT - This Segment rents equipment under
month-to-month rental contracts, provides services under both fixed-fee and
time-and-materials short-term contracts and, to a lesser extent, sells products
to customers. Equipment rentals are recognized as earned over the contractual
rental period. Services provided on a fixed-fee basis are recognized over the
contractual period based upon the completion of specific units of accounting
(i.e., erection and dismantling of equipment). Services provided on a
time-and-materials basis are recognized when earned as services are performed.
Product sales revenue is recognized when title and risk of loss transfer, and
when all of the revenue recognition criteria have been met.

      GAS TECHNOLOGIES SEGMENT - This Segment sells products under
customer-specific sales contracts. Product sales revenue is recognized when
title and risk of loss transfer, and when all of the revenue recognition
criteria have been met. Title and risk of loss for domestic shipments generally
transfers to the customer at the point of shipment. For international sales,
title and risk of loss transfer in accordance with the international commercial
terms included in the specific customer contract.

      ENGINEERED PRODUCTS AND SERVICES ("ALL OTHER") CATEGORY - This category
includes the Harsco Track Technologies, Reed Minerals, IKG Industries,
Patterson-Kelley and Air-X-Changers operating segments. These operating segments
principally sell products. The Harsco Track Technologies Division sells products
and provides services. Product sales revenue for each of these operating
segments is recognized generally when title and risk of loss transfer, and when
all of the revenue recognition criteria have been met. Title and risk of loss
for domestic shipments generally transfers to the customer at the point of
shipment. For export sales, title and risk of loss transfer in accordance with
the international commercial terms included in the specific customer contract.
Revenue may be recognized subsequent to the transfer of title and risk of loss
for certain product sales of the Harsco Track Technologies Division if the
specific sales contract includes a customer acceptance clause which provides for
different timing. In those situations revenue is recognized after transfer of
title and risk of loss and after customer acceptance. The Harsco Track
Technologies Division also provides services predominantly on a long-term,
time-and-materials contract basis. Revenue is recognized when earned 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. A valuation allowance to reduce deferred tax assets is evaluated on a
quarterly basis. The valuation allowance is principally for tax loss
carryforwards which are uncertain as to realizability. Income tax loss
contingencies are recorded in the period when it is determined that it is
probable that a liability has been incurred and the loss can be reasonably
estimated. Adjustments to estimated amounts are recorded as necessary based upon
new information, the occurrence of new events or the resolution of an
uncertainty. Beginning in 2007, income tax contingencies will be measured under
FASB Interpretation ("FIN") 48, "Accounting for Uncertainty in Income Taxes-an
interpretation of FASB Statement No. 109" ("FIN 48").

                                      -55-


ACCRUED INSURANCE AND LOSS RESERVES
The Company retains a significant portion of the risk for workers' compensation,
U.K. employers' liability, automobile, general and product liability losses.
During 2006, 2005 and 2004, the Company recorded insurance expense related to
these lines of coverage of approximately $44 million, $37 million and $37
million, respectively. Reserves have been recorded which reflect the
undiscounted estimated liabilities including claims incurred but not reported.
When a recognized liability is covered by third-party insurance, the Company
records an insurance claim receivable to reflect the covered liability. Changes
in the estimates of the reserves are included in net income in the period
determined. During 2006, the Company recorded a retrospective insurance reserve
adjustment that increased pre-tax insurance expense for self insured programs by
$1.2 million. In 2005 and 2004, the retrospective insurance reserve adjustments
decreased pre-tax insurance expense by $4.1 million and $2.7 million,
respectively. At December 31, 2006 and 2005, the Company has recorded
liabilities of $103.4 million and $102.3 million, respectively, related to both
asserted as well as unasserted insurance claims. Included in the balance at
December 31, 2006 and 2005 were $18.9 million and $25.2 million, respectively,
of recognized liabilities covered by insurance carriers. Amounts estimated to be
paid within one year have been classified as current Insurance liabilities, with
the remainder included in non-current Insurance liabilities in the Consolidated
Balance Sheets.

WARRANTIES
The Company has recorded product warranty reserves of $4.8 million, $5.0 million
and $4.2 million as of December 31, 2006, 2005 and 2004, respectively. The
Company provides for warranties of certain products as they are sold in
accordance with SFAS No. 5, "Accounting for Contingencies." The following table
summarizes the warranty activity for the years ended December 31, 2006, 2005 and
2004:

================================================================================

FOREIGN CURRENCY TRANSLATION
The financial statements of the Company's subsidiaries outside the United
States, except for those subsidiaries located in highly inflationary economies
and those entities for which the U.S. dollar is the currency of the primary
economic environment in which the entity operates, are 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 account, a separate component of Other comprehensive income (loss).
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, and those entities for
which the U.S. dollar is the currency of the primary economic environment in
which the entity operates, gains and losses on foreign currency transactions and
balance sheet translation adjustments are included in net income.

FINANCIAL INSTRUMENTS AND HEDGING
The Company has operations throughout the world that 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 foreign currency forward exchange contracts to hedge
transactions for firm purchase commitments, to hedge variable cash flows of
forecasted transactions and for export sales denominated in foreign currencies.
These contracts are generally for 90 days or less. For those contracts that are
designated as qualified

                                      -56-


cash flow hedges under SFAS No. 133, "Accounting for Derivative Instruments and
Hedging Activities" ("SFAS 133"), gains or losses are recorded in Other
comprehensive income (loss).

Amounts recorded in Other comprehensive income (loss) are reclassified into
income in the same period or periods during which the hedged forecasted
transaction affects income. The cash flows from these contracts are classified
consistent with the cash flows from the transaction being hedged (e.g., the cash
flows related to contracts to hedge the purchase of fixed assets are included in
cash flows from investing activities, etc.). The Company also enters into
certain forward exchange contracts not designated as hedges under SFAS 133.
Gains and losses on these contracts are recognized in income based on fair
market value. For fair value hedges of a firm commitment, the gain or loss on
the derivative and the offsetting gain or loss on the hedged firm commitment are
recognized currently in income.

OPTIONS FOR COMMON STOCK
In prior years, when stock options were issued to employees, the Company used
the intrinsic value method to account for the options. No compensation expense
was recognized on the grant date, since at that date, the option price equaled
the market price of the underlying common stock. Effective in 2002 and 2003, the
Company ceased granting stock options to employees and non-employee directors,
respectively.

The Company's net income and earnings per common share would have been reduced
to the pro forma amounts indicated below if compensation cost for the Company's
stock option plan had been determined based on the fair value at the grant date
for awards in accordance with the provisions of SFAS No. 123 (revised 2004),
"Share-Based Payment" ("SFAS 123(R)").

In 2004, the Board of Directors approved the granting of performance-based
restricted stock units as the long-term equity component of officer
compensation. See Note 12, "Stock-Based Compensation," for additional
information on the Company's equity compensation plans.

EARNINGS PER SHARE
Basic earnings per share are calculated using the average shares of common stock
outstanding, while diluted earnings per share reflect the dilutive effects of
restricted stock units and the potential dilution that could occur if stock
options were exercised. See Note 11, "Capital Stock," for additional information
on earnings per share.

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. Actual results could differ from
those estimates.

NEW FINANCIAL ACCOUNTING STANDARDS ISSUED

SFAS No. 155, "Accounting for Certain Hybrid Financial Instruments, an Amendment
--------------------------------------------------------------------------------
of FASB Statements No. 133 and 140" ("SFAS 155")
------------------------------------------------

In February 2006, the Financial Accounting Standards Board (FASB) issued SFAS
155, which amends SFAS No. 133, "Accounting for Derivative Instruments and
Hedging Activities," and SFAS No. 140, "Accounting for Transfers and Servicing
of Financial Assets and Extinguishments of Liabilities." SFAS 155 addresses
several issues relating to the
                                      -57-


accounting for financial instruments, including permitting fair value
measurement for any hybrid financial instrument that contains an embedded
derivative, and eliminating the prohibition on a qualifying special-purpose
entity from holding certain derivative instruments. SFAS 155 also provides
clarification that concentrations of credit risk in the form of subordination
are not embedded derivatives. SFAS 155 is effective for all financial
instruments issued or acquired after the fiscal year that begins after September
15, 2006 (January 1, 2007 for the Company), with early adoption permitted. The
Company implemented SFAS 155 effective January 1, 2007, and it did not have a
material impact on the Company's financial position, results of operations or
cash flows.

SFAS No. 156, "Accounting for Servicing of Financial Assets, an Amendment of
----------------------------------------------------------------------------
FASB Statement 140" ("SFAS 156")
--------------------------------

In March 2006, the FASB issued SFAS 156, which amends SFAS No. 140, "Accounting
of Transfers and Servicing of Financial Assets and Extinguishments of
Liabilities." SFAS 156 requires, in certain specified situations, an entity to
recognize a servicing asset or servicing liability when it undertakes an
obligation to service a financial asset by entering into a servicing contract.
SFAS 156 also requires all separately recognized servicing assets and servicing
liabilities to be initially recognized at fair value, if practical, and allows
entities to choose either the amortization method or the fair value measurement
method for subsequent measurement. SFAS 156 is effective for all servicing
transactions occurring on or after the beginning of the first fiscal year that
begins after September 15, 2006 (January 1, 2007 for the Company), with early
adoption permitted. The Company implemented SFAS 156 effective January 1, 2007,
and it did not have a material impact on the Company's financial position,
results of operations or cash flows.

FASB Interpretation ("FIN") 48, "Accounting for Uncertainty in Income Taxes-an
------------------------------------------------------------------------------
interpretation of FASB Statement No. 109" ("FIN 48")
----------------------------------------------------

In July 2006, the FASB issued FIN 48, which clarifies the accounting for
uncertainty in income taxes recognized in an entity's financial statements in
accordance with SFAS No. 109, "Accounting for Income Taxes." It prescribes a
recognition threshold and measurement attribute for financial statement
recognition and disclosure of tax positions taken or expected to be taken on a
tax return. The provisions of this interpretation are required to be adopted for
fiscal periods beginning after December 15, 2006. The Company will be required
to apply the provisions of FIN 48 to all tax positions upon initial adoption
with any cumulative effect adjustment to be recognized as an adjustment to
retained earnings.
 The Company is currently evaluating the requirements of FIN 48 and has not yet
determined the impact on the consolidated financial statements.

SFAS No. 157, "Fair Value Measurements" ("SFAS 157")
----------------------------------------------------

In September 2006, the FASB issued SFAS 157 to provide a single definition of
fair value, establish a framework for measuring fair value in U.S. generally
accepted accounting principles ("GAAP"), and expand the disclosure requirements
regarding fair value measurements. SFAS 157 is applicable in the application of
other accounting pronouncements that require or permit fair value measurements,
but does not require new fair value measurements. SFAS 157 is effective for
fiscal years beginning after November 15, 2007 (January 1, 2008 for the
Company), with limited retrospective application required. The Company is
currently evaluating the requirements of SFAS 157 and has not yet determined the
impact on the consolidated financial statements.

Staff Accounting Bulletin No. 108, "Considering the Effects of Prior Year
-------------------------------------------------------------------------
Misstatements When Quantifying Misstatements in Current Year Financial
----------------------------------------------------------------------
Statements" ("SAB 108")
-----------------------

In September 2006, the SEC issued SAB 108 to provide guidance for quantifying
and evaluating the materiality of a misstatement. SAB 108 indicates that an
entity should use both a balance sheet (iron curtain) approach and an income
statement (rollover) approach when quantifying and evaluating the materiality of
a misstatement, and provides guidance for using the dual approach. SAB 108 also
provides transition guidance for correcting errors existing in prior years. SAB
108 is effective for annual financial statements covering the first fiscal year
ending after November 15, 2006 (December 31, 2006 for the Company). The Company
implemented SAB 108 effective December 31, 2006, and it did not have an impact
on the Company's financial position, results of operations or cash flows as
there were no misstatements that required evaluation under the standard.

SFAS No. 158, "Employer's Accounting for Defined Benefit Pension and Other
--------------------------------------------------------------------------
Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106, and
--------------------------------------------------------------------------
132(R)" ("SFAS 158")
--------------------

The FASB is currently reconsidering the accounting for pensions and other
postretirement benefits in a two-phase project. Phase I of this project
primarily addresses the balance sheet recognition of a plan's overfunded or
underfunded status. Phase II will be a comprehensive reconsideration of all
elements of pension accounting, and is expected to take several years to
complete once Phase I is complete. As part of Phase I, the FASB issued SFAS 158

                                      -58-


in September 2006. Included in SFAS 158 is a requirement for an entity to
recognize in its balance sheet, the overfunded or underfunded status of its
defined benefit postretirement plans measured as the difference between the fair
value of the plan assets and the benefit obligation. For a pension plan, this
would be the projected benefit obligation; for any other postretirement plan,
the benefit obligation would be the accumulated postretirement benefit
obligation. SFAS 158 also eliminates the early measurement dates by requiring
the pension plan obligation to be measured as of the date of the entity's
balance sheet. The requirement to recognize the funded status of the pension
plans is effective for publicly-held companies for fiscal years ending after
December 15, 2006 (December 31, 2006 for the Company). The requirement to
measure the pension obligation as of the entity's balance sheet date is
effective for fiscal years ending after December 15, 2008 (December 31, 2008 for
the Company). The Company implemented Phase I of SFAS 158 effective December 31,
2006. This reduced the Company's equity on an after-tax basis by approximately
$88.2 million compared with measurement under prior standards. The results of
operations were not affected. The adoption of SFAS 158 did not have a negative
impact on compliance with the Company's debt covenants.

SFAS No. 159, "The Fair Value Option for Financial Assets and Financial
-----------------------------------------------------------------------
Liabilities" ("SFAS 159").
--------------------------

In February 2007, the FASB issued SFAS 159, which permits all entities to choose
to measure eligible items at fair value at specified election dates. Unrealized
gains and losses on items for which the fair value option has been elected will
be reported in earnings at each subsequent reporting date. The fair value option
may be applied financial instrument by financial instrument (with limited
exceptions), is generally irrevocable, and must be applied to the entire
financial instrument. SFAS 159 is effective for fiscal years that begin after
November 15, 2007 (January 1, 2008 for the Company). The Company is currently
evaluating the requirements of SFAS 159, and has not yet determined the impact
on the consolidated financial statements.


2. ACQUISITIONS AND DISPOSITIONS

ACQUISITIONS
In February 2007, the Company acquired Excell Materials, Inc. ("Excell"), a
Pittsburgh-based multinational company, for approximately $200 million, subject
to various adjustments. Excell specializes in the reclamation and recycling of
high-value content from steelmaking slag. Excell is also involved in the
development of minerals technologies for commercial applications. Excell
recorded 2006 sales in excess of $100 million and maintains operations at nine
locations in the United States, Canada, Brazil, and South Africa.

In November 2006, the Company acquired the Santiago, Chile-based company
Moldajes y Andamios TH S.A. ("MyATH"), a supplier of rental formwork,
scaffolding and related services to the construction, infrastructure and
building maintenance sectors. MyATH employs approximately 100 people and its
annual revenues are approximately $8 million. MyATH has been included in the
Hunnebeck Division of the Access Services Segment.

In November 2006, the Company acquired the conveyor services and trading arm of
Technic Gum, a Belgium-based provider of conveyor belt maintenance services for
the steel and cement-producing industries. Technic Gum recorded revenues of
approximately $8 million in 2005 and employs approximately 50 people. Technic
Gum has been included in the Mill Services Segment.

In July 2006, the Company acquired the assets of UK-based Cape PLC's Cleton
industrial maintenance services ("Cleton") subsidiaries in Holland, Belgium and
Germany for (euro)8 million (approximately $10 million). Cleton posted 2005
revenues in excess of $50 million and employs close to 400 people. Cleton
specializes in providing scaffolding and related insulation services for the
maintenance of large-scale industrial plants, and serves some of the largest oil
refinery, petrochemical, and process plant sites in the Benelux countries.
Cleton has been included in the SGB Division of the Access Services Segment.

In December 2005, the Company acquired the Northern Hemisphere steel mill
services operations of Brambles Industrial Services ("BISNH"), a unit of the
Sydney, Australia-based Brambles Industrial Limited, for (pound)136 million
(approximately $235 million), excluding acquisition costs. BISNH has been
included in the Company's Mill Services Segment. The Company did not assume debt
as part of this acquisition. BISNH is a provider of on-site, outsourced mill
services to the steel and metals industries, operating at 19 locations in the
U.K., France, Holland and the United States. Goodwill recognized in this
transaction (based on foreign exchange rates at the transaction date) was $96.3
million, of which $91.8 million is expected to be deductible for U.S. income tax
purposes.

In November 2005, the Company acquired the Germany-based Hunnebeck Group GmbH
(Hunnebeck) for (euro)140 million (approximately $164 million), which included
the assumption of debt but excluded acquisition costs.

                                      -59-


Hunnebeck has been included in the Company's Access Services Segment. Hunnebeck
is a provider of highly engineered formwork and scaffolding equipment with more
than 60 branches and depots in 12 countries and export sales worldwide. Goodwill
recognized in this transaction (based on foreign exchange rates at the
transaction date) was $67.8 million, none of which is expected to be deductible
for U. S. income tax purposes.

DISPOSITIONS - ASSETS HELD FOR SALE AND DISCONTINUED OPERATIONS
In January 2007, the Company's Board of Directors approved the divestiture of
its Gas Technologies Segment. This Segment recorded revenues and operating
income of $397.7 million and $14.2 million, respectively, for 2006. The Company
expects the divestiture to occur in the second half of 2007. Results of the
Segment will be included in Discontinued Operations of the income statement
effective with the first quarter 2007 report. The Segment's assets and
liabilities will be classified as held-for-sale in the Company's first quarter
2007 balance sheet.

Throughout the past several years, management approved the sale of certain
long-lived assets (primarily land and buildings) throughout the Company's
operations. The major classes of assets held-for-sale included in the
Consolidated Balance Sheets are as follows:

3. ACCOUNTS RECEIVABLE AND INVENTORIES

At December 31, 2006 and 2005, accounts receivable of $753.2 million and $666.3
million, respectively, were net of allowances for doubtful accounts of $25.4
million and $24.4 million, respectively. Gross accounts receivable included
trade accounts receivable of $737.1 million and $638.5 million at December 31,
2006 and 2005, respectively. Other receivables included insurance claim
receivables of $18.9 million and $25.2 million at December 31, 2006 and 2005,
respectively. The increase in accounts receivable and the allowance for doubtful
accounts from December 31, 2005 related principally to increased sales, foreign
currency translation and the net effect of acquisitions and divestitures
discussed in Note 2, "Acquisitions and Dispositions." The provision for doubtful
accounts was $9.2 million, $6.5 million and $5.0 million for 2006, 2005 and
2004, respectively.

Inventories consist of the following:

                                                        INVENTORIES

   ===========================================================================

The increase in inventory balances related principally to increased demand in
the Access Services Segment, increased demand and the timing of purchases and
shipments in the Gas Technologies Segment, and foreign currency translation.

Inventories valued on the LIFO basis at December 31, 2006 and 2005 were
approximately $46.1 million and $34.1 million, respectively, less than the
amounts of such inventories valued at current costs.

                                      -60-


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 $0.11 million, $1.6 million and $0.02 million in 2006,
2005 and 2004, respectively.

4. PROPERTY, PLANT AND EQUIPMENT

Property, plant and equipment consists of the following:

   (IN THOUSANDS)                                      2006            2005

   ---------------------------------------------------------------------------
   Net property, plant and equipment               $1,322,467      $1,139,808
   ===========================================================================

The increase in net property, plant and equipment from 2005 to 2006 related
principally to investments in the Mill Services and Access Services Segments.

The estimated useful lives of different types of assets are generally:

   Land improvements                               5 to 20 years

   Buildings and improvements                      5 to 40 years

   Machinery and equipment                         3 to 20 years

   Leasehold improvements             Estimated useful life of the improvement
                                      or, if shorter, the life of the lease


5. GOODWILL AND OTHER INTANGIBLE ASSETS

In connection with the provisions of SFAS No. 142, "Goodwill and Other
Intangible Assets," (SFAS 142) goodwill and intangible assets with indefinite
useful lives are no longer amortized. Goodwill is tested for impairment at the
reporting unit level on an annual basis, and between annual tests, whenever
events or circumstances indicate that the carrying value of a reporting unit's
goodwill may exceed its fair value. This impairment testing is a two-step
process as outlined in SFAS 142. Step one is a comparison of each reporting
unit's fair value to its book value. If the fair value of the reporting unit
exceeds the book value, step two of the test is not required. Step two requires
the allocation of fair values to assets and liabilities as if the reporting unit
had just been purchased resulting in the implied fair value of goodwill. If the
carrying value of the goodwill exceeds the implied fair value, a write down to
the implied fair value would be required.

The Company uses a discounted cash flow model to estimate the fair value of a
reporting unit in performing step one of the testing. This model requires the
use of long-term planning estimates and assumptions regarding industry-specific
economic conditions that are outside the control of the Company. The Company
performed required annual testing for goodwill impairment as of October 1, 2006
and 2005 and all reporting units of the Company passed the step one testing
thereby indicating that no goodwill impairment exists. However, there can be no
assurance that future goodwill impairment tests will not result in a charge to
earnings.

                                      -61-

The Company has various credit facilities and commercial paper programs
available for use throughout the world. The following table illustrates the
amounts outstanding on credit facilities and commercial paper programs and
available credit at December 31, 2006. As of December 31, 2006, the Company
limited the aggregate commercial paper, syndicated credit facility and bilateral
credit facility borrowings at any one time to a maximum of $600 million.
Effective February 1, 2007, with the increase in the supplemental credit
facility to $250 million as indicated below, this maximum was increased to $750
million to provide additional financial flexibility for growth-related
investments. These credit facilities and programs are described in more detail

       commercial paper program from $400 million to $550 million.
 (b)   U.S.-based program
 (c)   This facility was increased to $250 million effective February 1, 2007.
 (d)   International-based program
 (e)   Although the Company has significant available credit, as of
       December 31, 2006, it was the Company's policy to limit aggregate
       commercial paper and credit facility borrowings at any one time to a
       maximum of $600 million. Effective February 1, 2007, this maximum
       was increased to $750 million.

The Company has a U.S. commercial paper borrowing program under which it can
issue up to $550 million of short-term notes in the U.S. commercial paper
market. In addition, the Company has a 200 million euro commercial paper
program, equivalent to approximately $264 million at December 31, 2006, which is
used to fund the Company's international operations. Commercial paper interest
rates, which are based on market conditions, have been lower than comparable
rates available under the credit facilities. At December 31, 2006 and 2005, the
Company had $263.4 million and $351.3 million of U.S. commercial paper
outstanding, respectively, and $207.2 million and $127.4 million outstanding,
respectively, under its European-based commercial paper program. Commercial
paper is classified as long-term debt when the Company has the ability and
intent to refinance it on a long-term basis through existing long-term credit
facilities. At December 31, 2006 and 2005, the Company classified $161.5 million
and $88.7 million of commercial paper as short-term debt, respectively. The
remaining $309.1 million and $390.1 million in commercial paper at December 31,
2006 and 2005, respectively, was classified as long-term debt.

The Company has a revolving credit facility in the amount of $450 million,
through a syndicate of 16 banks, which matures in November 2010. This facility
serves as back-up to the Company's commercial paper programs. Interest rates on
the facility are based upon the London Interbank Offered Rate (LIBOR) plus a
margin. The Company pays a facility fee (.08% per annum as of December 31, 2006)
that varies based upon its credit ratings. At December 31, 2006 and 2005, there
were no borrowings outstanding on this credit facility.

On December 22, 2006, the Company renewed its supplemental 364-day credit
facility in the amount of $100 million, through two banks, which now matures in
December 2007. On February 1, 2007, the Company increased its supplemental
364-day credit facility to $250 million. This facility also serves as back-up to
the Company's commercial paper programs. Interest rates on the facility are
based upon either the announced Citicorp lending rate, the Federal Funds
Effective Rate plus a margin or LIBOR plus a margin. The Company pays a facility
fee (.08% per annum as of December 31, 2006) that varies based upon its credit
ratings. As of December 31, 2006 and 2005, there were no borrowings outstanding
on this credit facility.

The bilateral credit facility was renewed in December 2006 for an additional one
year. The facility serves as back-up to the Company's commercial paper programs
and also provides available financing for the Company's European operations.
Borrowings under this facility, which expires in December 2007, are available in
most major currencies with active markets at interest rates based upon LIBOR
plus a margin. Borrowings outstanding at expiration may be repaid over the
succeeding 12 months. As of December 31, 2006 and 2005, there were no borrowings
outstanding on this facility.

Short-term debt amounted to $185.1 million and $98.0 million (of which $161.5
million and $88.7 million was commercial paper) at December 31, 2006 and 2005,
respectively. Other than the commercial paper borrowings, short-term debt was
principally bank overdrafts. The weighted-average interest rate for short-term
borrowings at December 31, 2006 and 2005 was 4.8% and 4.0%, respectively.

The Company's credit facilities and certain notes payable agreements contain
covenants requiring a minimum net worth of $475 million and a maximum debt to
capital ratio of 60%. Additionally, the Company's 7.25% British pound
sterling-denominated notes due October 27, 2010 include a covenant that permits
the note holders to redeem their notes, at par, in the event of a change of
control of the Company. At December 31, 2006, the Company was in compliance with
these covenants.

The maturities of long-term debt for the four years following December 31, 2007

8. EMPLOYEE BENEFIT PLANS

PENSION BENEFITS
In September 2006, the FASB issued SFAS No. 158, "Employers' Accounting for
Defined Benefit Pension and Other Postretirement Plans" ("SFAS 158"). The
Company adopted the recognition provisions of SFAS 158 effective December 31,
2006. The impact of adopting SFAS 158 has been reflected in the consolidated
financial statements as of December 31, 2006 and the incremental effect of
applying SFAS 158 is disclosed below.

The Company has pension and profit sharing retirement plans covering a
substantial number of its employees. The defined 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 also makes periodic voluntary contributions
as recommended by its pension committee. The Company's policy is to amortize
prior service costs of defined benefit pension plans over the average future
service period of active plan participants. The Company uses an October 31
measurement date for its United States defined benefit pension plans and
recently acquired international plans. A September 30 measurement date is used
for other international defined benefit pension plans.

For a majority of the U.S. defined benefit pension plans and certain
international defined benefit pension plans, accrued service is no longer
granted for periods after December 31, 2003. In place of these plans, the
Company has established, effective January 1, 2004, defined contribution pension
plans providing for the Company to contribute a specified matching amount for
participating employees' contributions to the plan. Domestically, this match is
made on employee contributions up to four percent of their eligible
compensation. Additionally, the Company may provide a discretionary contribution
of up to two percent of compensation for eligible employees. The two percent
discretionary contribution was recorded for the last three years, 2006, 2005 and
2004, and paid in February of the subsequent year. Internationally, this match
is up to six percent of eligible compensation with an additional two percent
going towards insurance and administrative costs. The Company believes the
defined contribution plans will provide a more predictable and less volatile
pension expense than exists under the defined benefit plans.

(a) Balances represent major captions as presented on the Consolidated Balance
    Sheet.

The Company's best estimate of expected contributions to be paid in year 2007
for the U.S. defined benefit plans is $2.4 million and for the international
defined benefit plans is $23.2 million.

On August 17, 2006, the Pension Protection Act of 2006 (the "Act") was signed
into law. Key provisions of the Act include a requirement to fully fund U.S.
defined benefit pension plans within seven years and an increase in the annual
income tax deduction limit applicable to pension plans. The Company is currently
evaluating the impact of the Act on its cash flows; however, it is not expected
to materially impact the Company's cash flows for any given period.

Contributions to multi-employer pension plans were $18.3 million, $13.6 million
and $15.2 million in years 2006, 2005 and 2004, respectively. For defined
contribution plans, payments were $13.7 million, $12.9 million and $9.7 million
for years 2006, 2005 and 2004, respectively.

The U.S. discount rate was determined using a yield curve that was produced from
a universe containing over 500 U.S.-issued, AA-graded corporate bonds, all of
which were noncallable (or callable with make-whole provisions), and excluding
the 10% of the bonds with the highest yields and the 10% with the lowest yields.
The discount rate was then developed as the level-equivalent rate that would
produce the same present value as that using spot rates to discount the
projected benefit payments. For international plans, the discount rate is
aligned to Corporate bond yields in the local markets, normally AA-rated
Corporations. The process and selection seeks to approximate the cash outflows
with the timing and amounts of the expected benefit payments. As of the
September 30, 2006 measurement date, these rates have declined by 10 basis
points from the prior year.

The asset allocations attributable to the Company's U.S. defined benefit pension
plans at October 31, 2006 and 2005 and the target allocation of plan assets for
2007, by asset category, are as follows:

Plan assets are allocated among various categories of equities, fixed income,
cash and cash equivalents with professional investment managers whose
performance is actively monitored. The primary investment objective is long-term
growth of assets in order to meet present and future benefit obligations. The
Company periodically conducts an asset/liability modeling study to ensure the
investment strategy is aligned with the profile of benefit obligations.

The Company reviews the long-term expected return-on-asset assumption on a
periodic basis taking into account a variety of factors including the historical
investment returns achieved over a long-term period, the targeted allocation of
plan assets and future expectations based on a model of asset returns for an
actively managed portfolio, inflation and administrative/other expenses. The
model simulates 500 different capital market results over 15 years. For 2007,
the expected return-on-asset assumption for U.S. plans is 8.25%, consistent with
the expected return-on-asset assumption for 2006.

The U.S. defined benefit pension plans assets include 382,640 shares of the
Company's stock valued at $31.3 million and $24.4 million on October 31, 2006
and 2005, respectively, representing 11.5% and 9.9%, respectively, of total plan
assets. As part of a rebalancing of the pension fund to further diversify the
plan assets, approximately one-half of the pension fund's holdings in the
Company's stock were sold in the second quarter of 2004. As of December 31,
2006, the Company's stock represented 10.3% of total plan assets. The Company is
considering a further rebalancing of the Company's stock in the pension fund
during 2007. Dividends paid to the pension plans on the Company stock amounted
to $0.5 million in 2006 and $0.4 million in 2005.

Plan assets as of September 30, 2006, in the United Kingdom (U.K.) defined
benefit pension plan amounted to 90% of the international pension assets. These
assets were divided into portfolios representing various categories of equities,
fixed income, cash and cash equivalents managed by a number of professional
investment managers.

The primary investment objective is long-term growth of assets in order to meet
present and future benefit obligations. The Company periodically conducts
asset/liability modeling studies to ensure the investment strategies are aligned
with the profile of benefit obligations. For the international long-term
rate-of-return assumption, the Company considered the current level of expected
returns in risk-free investments (primarily government bonds), the historical
level of the risk premium associated with other asset classes in which the
portfolio is invested and the expectations for future returns of each asset
class and plan expenses. The expected return for each asset class was then
weighted based on the target asset allocation to develop the expected long-term
rate-of-return on assets. The Company's expected rate-of-return assumption for
the U.K. plan was 7.50% for both 2007 and 2006. The remaining international
pension plans with assets representing 10% of the international pension assets
are under the guidance of professional investment managers and have similar
investment objectives.

POSTRETIREMENT BENEFITS
The Company has postretirement health care benefits for a limited number of
employees mainly under plans related to acquired companies and postretirement
life insurance benefits for certain hourly employees. The costs of health care
and life insurance 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
Company uses an October 31 measurement date for its postretirement benefit
plans.

================================================================================

The curtailment gains of $0.3 million for 2005 and $2.2 million for 2004 were
due to the termination of certain retiree health care plans.

Effective October 31, 2004, the Company adopted the provisions of Financial
Accounting Standards Board Staff Position No. 106-2, "Accounting and Disclosure
Requirements Related to the Medicare Prescription Drug, Improvement and
Modernization Act of 2003" ("FSP FAS 106-2"). Adoption of FSP FAS 106-2 reduced
the Company's accumulated postretirement benefit obligation by $0.3 million as
of December 31, 2004. This amount was treated as an unrecognized actuarial gain.
The Company deferred re-measurement of its postretirement health care benefit
obligation until its measurement date, so there was no effect on 2004 reported
expense. The expense for 2006 and 2005 decreased by $29 thousand and $36
thousand, respectively, after reflecting the value of the federal subsidy.

SAVINGS PLAN
Prior to January 1, 2004, the Company had a 401(k) Savings Plan ("the Savings
Plan") which covered substantially all U.S. employees with the exception of
employees represented by a collective bargaining agreement, unless the agreement
expressly provides otherwise. Effective January 1, 2004, certain U.S. employees
previously covered by the Savings Plan were transferred into the Harsco
Retirement Savings and Investment Plan ("HRSIP") which is a defined contribution
pension plan. The transferred employees were those whose credited years of
service under the qualified Defined Benefit Pension Plan were frozen as of
December 31, 2003. Employees whose credited service was not frozen as of
December 31, 2003 remained in the Savings Plan. The expenses related to the
HRSIP are included in the defined contribution pension plans disclosure in the
Pension Benefits section of this footnote.

Employee contributions to the Savings Plan are generally determined as a
percentage of covered employees' compensation. The expense for contributions to
the Savings Plan by the Company was $0.9 million, $0.9 million and $0.4 million
for 2006, 2005 and 2004, respectively.

Employee directed investments in the Savings Plan and HRSIP include the
following amounts of Company stock:

EXECUTIVE INCENTIVE COMPENSATION PLAN
The amended 1995 Executive Incentive Compensation Plan provides the basis for
determination of annual incentive compensation awards under a performance-based
Economic Value Added (EVA(R)) plan. Actual cash awards are usually paid in
January or February of the following year. The Company accrues amounts
reflecting the estimated value of incentive compensation anticipated to be
earned for the year. Total executive incentive compensation expense was $7.7
million, $6.1 million and $4.5 million in 2006, 2005 and 2004, respectively. The
2006 and 2005 expenses included performance-based restricted stock units
("RSUs") that were granted to certain officers and key employees of the Company.
There were no RSUs granted to officers or employees in 2004. See Note 12,
"Stock-Based Compensation," for additional information on the equity component
of executive compensation.

The difference in effective tax rates on international earnings and remittances
from 2005 to 2006 includes a one-time benefit recorded in the fourth quarter of
2005 of $2.7 million associated with funds repatriated under the American Jobs
Creation Act of 2004 ("AJCA"). Additionally, during the fourth quarter of 2005,
consistent with the Company's strategic plan of investing for growth, the
Company designated certain international earnings as permanently reinvested
which resulted in a one-time income tax benefit of $3.6 million.

At December 31, 2006, the tax effected amount of net operating loss
carryforwards ("NOLs") totaled $18.4 million. Of that amount, $8.6 million is
attributable to international operations and can be carried forward
indefinitely. Tax effected U.S. federal NOLs are $1.2 million and expire in
2018. Tax effected U.S. state NOLs are $8.6 million. Of that amount, $0.9
million expire in 2007-2013, $0.7 million expire in 2014-2021, and $7.0 million
expire in 2026. Included in the above-mentioned total are $1.2 million of
preacquisition NOLs.

The valuation allowance of $13.9 million and $21.7 million at December 31, 2006
and 2005, respectively, related principally to NOLs 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 goodwill.

The change in the valuation allowances for 2006 and 2005 results primarily from
the utilization of NOLs, the release of valuation allowances in certain
jurisdictions based on the Company's revaluation of the realizability of future
benefits and the increase in valuation allowances in certain jurisdictions based
on the Company's revaluation of the realizability of future benefits.

The Company has not provided U.S. income taxes on certain of its non-U.S.
subsidiaries' undistributed earnings as such amounts are permanently reinvested
outside the U.S. At December 31, 2006 and 2005, such earnings were approximately
$425 million and $295 million, respectively. If these earnings were repatriated
at December 31, 2006, the one time tax cost associated with the repatriation
would be approximately $48 million. The Company has various tax holidays in
Europe, the Middle East and Asia that expire between 2005 and 2010. During 2006,
2005 and 2004, these tax holidays resulted in approximately $3.6 million, $2.4
million and $4.2 million, respectively, in reduced income tax expense.

On October 22, 2004, the AJCA was signed into law. The AJCA included a deduction
of 85% for certain international earnings that are repatriated, as defined in
the AJCA, to the U.S. The Company completed its evaluation of the repatriation
provisions of the AJCA and repatriated qualified earnings of approximately $24
million in the fourth quarter

                                      -75-


of 2005. This resulted in the Company receiving a one-time income tax benefit of
approximately $2.7 million during the fourth quarter of 2005.


10. COMMITMENTS AND 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 Sheets at December 31, 2006 and 2005 include accruals of
$3.8 million and $2.8 million, respectively, for environmental matters. The
amounts charged against pre-tax income related to environmental matters totaled
$2.2 million, $1.5 million and $2.1 million in 2006, 2005 and 2004,
respectively.

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,
results of operations or cash flows.

ROYALTY EXPENSE DISPUTE
The Company is involved in a royalty expense dispute with the Canada Revenue
Agency ("CRA"). The CRA is proposing to disallow certain royalty expense
deductions claimed by the Company's Canadian subsidiary on its 1994-1998 tax
returns. As of December 31, 2006, the maximum assessment from the CRA for the
period 1994-1998 is approximately $10.4 million including tax and interest. The
Ontario Ministry of Finance ("Ontario") is also proposing to disallow these same
deductions for the period 1994-1998. As of December 31, 2006, the maximum
assessment from Ontario is approximately $3.3 million, including tax and
interest. The Company has filed administrative appeals and will vigorously
contest these disallowances.

The Company currently anticipates that, ultimately, it may have liability for
some portion of the assessment in this royalty expense dispute. However, the
Company intends to utilize competent authority proceedings in the U.S. to
recover a portion of any required tax payment amount. The Company believes that
any amount not recovered through these proceedings has been fully reserved as of
December 31, 2006 and, therefore will not have a material adverse effect on the
Company's future results of operations or financial condition. In accordance
with Canadian tax law, the Company made a payment to the CRA in the fourth
quarter of 2005 of $5.0 million. Additionally, the Company made a payment to the
Ontario Ministry of Finance in the first quarter of 2006 for the entire disputed
amount. These payments were made for tax compliance purposes and to reduce
potential interest expense on the disputed amount. These payments in no way
reflect the Company's acknowledgement as to the validity of the assessed
amounts.

DERAILMENT
One of the Company's production rail grinders derailed near Baxter, California
on November 9, 2006, resulting in two crew member fatalities and the near total
loss of the rail grinder. Government and private investigations into the cause
of the derailment are on-going. Most of the clean-up and salvage efforts are
completed, although work on environmental remediation is on-going. Estimated
environmental remediation expenses have been recognized as of December 31, 2006.
All remaining Company rail grinders have been inspected by the Federal Railroad
Administration ("FRA") and each grinder is fully operational and in compliance
with legal requirements. The Company has also conducted its own inspections to
ensure that its grinders are safe and in compliance with contractual
commitments. The Company believes that the insurance proceeds from the loss of
the rail grinder will offset the majority of incurred expenses, which have been
recognized as of December 31, 2006. Therefore, the Company does not believe that
the derailment will have a material adverse effect on its financial position,
results of operations or cash flows.

OTHER
The Company has been named as one of many defendants (approximately 90 or more
in most cases) in legal actions alleging personal injury from exposure to
airborne asbestos over the past several decades. In their suits, the plaintiffs
have named as defendants, among others, many manufacturers, distributors and
installers of numerous types of equipment or products that allegedly contained
asbestos.

                                      -76-


The Company believes that the claims against it are without merit. The Company
has never been a producer, manufacturer or processor of asbestos fibers. Any
component within a Company product which may have contained asbestos would have
been purchased from a supplier. Based on scientific and medical evidence, the
Company believes that any asbestos exposure arising from normal use of any
Company product never presented any harmful levels of airborne asbestos
exposure, and moreover, the type of asbestos contained in any component that was
used in those products was protectively encapsulated in other materials and is
not associated with the types of injuries alleged in the pending suits. Finally,
in most of the depositions taken of plaintiffs to date in the litigation against
the Company, plaintiffs have failed to specifically identify any Company
products as the source of their asbestos exposure.

The majority of the asbestos complaints pending against the Company have been
filed in New York. Almost all of the New York complaints contain a standard
claim for damages of $20 million or $25 million against the approximately 90
defendants, regardless of the individual plaintiff's alleged medical condition,
and without specifically identifying any Company product as the source of
plaintiff's asbestos exposure.

As of December 31, 2006, there are 26,440 pending asbestos personal injury
claims filed against the Company. Of these cases, 26,111 were pending in the New
York Supreme Court for New York County in New York State. The other claims,
totaling 329, are filed in various counties in a number of state courts, and in
certain Federal District Courts (including New York), and those complaints
generally assert lesser amounts of damages than the New York State court cases
or do not state any amount claimed.

As of December 31, 2006, the Company has obtained dismissal by stipulation, or
summary judgment prior to trial, in 16,953 cases.

In view of the persistence of asbestos litigation nationwide, which has not yet
been sufficiently addressed either politically or legally, the Company expects
to continue to receive additional claims. However, there have been developments
during the past several years, both by certain state legislatures and by certain
state courts, which could favorably affect the Company's ability to defend these
asbestos claims in those jurisdictions. These developments include procedural
changes, docketing changes, proof of damage requirements and other changes that
require plaintiffs to follow specific procedures in bringing their claims and to
show proof of damages before they can proceed with their claim. An example is
the action taken by the New York Supreme Court (a trial court), which is
responsible for managing all asbestos cases pending within New York County in
the State of New York. This Court issued an order in December 2002 that created
a Deferred or Inactive Docket for all pending and future asbestos claims filed
by plaintiffs who cannot demonstrate that they have a malignant condition or
discernable physical impairment, and an Active or In Extremis Docket for
plaintiffs who are able to show such medical condition. As a result of this
order, the majority of the asbestos cases filed against the Company in New York
County have been moved to the Inactive Docket until such time as the plaintiff
can show that they have incurred a physical impairment. As of December 31, 2006,
the Company has been listed as a defendant in 248 Active or In Extremis asbestos
cases in New York County. The Court's Order has been challenged by plaintiffs.

The Company's insurance carrier has paid all legal and settlement costs and
expenses to date. The Company has liability insurance coverage under various
primary and excess policies that the Company believes will be available, if
necessary, to substantially cover any liability that might ultimately be
incurred on these claims.

The Company intends to continue its practice of vigorously defending these cases
as they are listed for trial. It is not possible to predict the ultimate outcome
of asbestos-related lawsuits, claims and proceedings due to the unpredictable
nature of personal injury litigation. Despite this uncertainty, and although
results of operations and cash flows for a given period could be adversely
affected by asbestos-related lawsuits, claims and proceedings, management
believes that the ultimate outcome of these cases will not have a material
adverse effect on the Company's financial condition, results of operations or
cash flows.

The Company is subject to various other claims and legal proceedings 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, as would not have a material adverse effect on the
financial position, results of operations or cash flows of the Company.

Insurance liabilities are recorded in accordance with SFAS 5, "Accounting for
Contingencies." Insurance reserves have been estimated based primarily upon
actuarial calculations and reflect the undiscounted estimated liabilities for
ultimate losses including claims incurred but not reported. Inherent in these
estimates are assumptions which are based on the Company's history of claims and
losses, a detailed analysis of existing claims with respect to potential value,
and current legal and legislative trends. If actual claims differ from those
projected by management, changes

                                      -77-


(either increases or decreases) to insurance reserves may be required and would
be recorded through income in the period the change was determined. When a
recognized liability is covered by third-party insurance, the Company records an
insurance claim receivable to reflect the covered liability. See Note 1,
"Summary of Significant Accounting Policies," for additional information on
Accrued Insurance and Loss Reserves.


11. CAPITAL STOCK

The authorized capital stock of the Company 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. Under that
Plan, the Board declared a dividend to stockholders 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, 2006,
750,000 shares of $1.25 par value preferred stock were reserved for issuance
upon exercise of the rights.

The Board of Directors has authorized the repurchase of shares of common stock
as follows:

          NO. OF SHARES                                        REMAINING NO. OF

================================================================================
(a)  The 133 shares purchased were not part of the share repurchase program.
     They were shares which a retired employee sold to the Company in order to
     pay personal federal and state income taxes on shares issued to the
     employee upon retirement.

In November 2006, the Board of Directors extended the share purchase
authorization through January 31, 2008 for the 1,000,000 shares still remaining
from the prior authorization.

In 2006, 2005 and 2004, additional issuances of treasury shares of 1,766 shares,
5,306 shares and 11,195 shares, respectively, were made for SGB stock option
exercises, employee service awards and shares related to vested restricted stock
units.

All outstanding stock options were included in the computation of diluted
earnings per share at December 31, 2006, 2005 and 2004.

On January 23, 2007, the Company's Board of Directors approved a two-for-one
stock split. One additional share of common stock will be issued on March 26,
2007, to stockholders of record at the close of business on February 28, 2007.

The total number of authorized common stock shares and par value were unchanged
by this action. The stock split will require retroactive restatement of all
historical share and per share data in the first quarter ending on March 31,
2007. Stockholder's equity will also be restated to give retroactive recognition
of the stock split. For all periods presented, the par value of the additional
shares resulting from the split will be reclassified from Additional paid-in
capital to Common stock.

All references to the number of shares and per share amounts in the Consolidated
Financial Statements for the years 2006, 2005 and 2004 are presented on a
pre-split basis.

12. STOCK-BASED COMPENSATION

Effective January 1, 2006, the Company adopted SFAS No. 123 (revised 2004),
"Share-Based Payments" ("SFAS 123(R)"), which replaced SFAS No. 123, "Accounting
for Stock-Based Compensation," and superseded Accounting Principles Board
("APB") Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB 25").
SFAS 123(R) requires the cost of employee services received in exchange for an
award of equity instruments to be based upon the grant-date fair value of the
award (with limited exceptions). Additionally, this cost is to be recognized as
expense over the period during which an employee is required to provide services
in exchange for the award (usually the vesting period). However, this
recognition period would be shorter if the recipient becomes retirement-eligible
prior to the vesting date. SFAS 123(R) also requires that the additional tax
benefits the Company receives from stock-based compensation be recorded as cash
inflows from financing activities in the statement of cash flows. Prior to
January 1, 2006, the Company applied the provisions of APB 25 in accounting for
awards made under the Company's stock-based compensation plans.

The Company adopted the provisions of SFAS 123(R) using the modified-prospective
transition method. Under this method, results from prior periods have not been
restated. During 2002 and 2003, the Company ceased granting stock options to
employees and non-employee directors, respectively. Primarily because of this,
the effect of adopting SFAS 123(R) was not material to the Company's income from
continuing operations, income before income taxes, net income, basic or diluted
earnings per share or cash flows from operating and financing activities for the
year ended December 31, 2006, and the cumulative effect of adoption using the
modified-prospective transition method was not material. In addition, the
Company elected to use the short-cut transition method for calculating the
historical pool of windfall tax benefits.

In 2004, the Board of Directors approved the granting of performance-based
restricted stock units as the long-term equity component of director, officer
and certain key employee compensation. The restricted stock units require no
payment from the recipient and compensation cost is measured based on the market
price on the grant date and is generally recorded over the vesting period. The
vesting period for restricted stock units granted to non-employee directors is
one year and each restricted stock unit will be exchanged for a like number of
shares of Company stock following the termination of the participant's service
as a director. The vesting period for restricted stock units granted to officers
and certain key employees is three years, and, upon vesting, each restricted
stock unit will be exchanged for a like number of shares of the Company's stock.
In September 2006, the Board of Directors approved changes to the employee
restricted stock units program where future awards will vest on a pro rata basis
over a three-year period and the specified retirement age will be 62. This
compares with the prior three-year cliff vesting and retirement age of 65.
Restricted stock units do not have an option for cash payment.

NONVESTED AT DECEMBER 31, 2006              72,617            $  61.76
============================================================================

As of December 31, 2006, the total unrecognized compensation costs related to
nonvested restricted stock units was $2.7 million which is expected to be
recognized over a weighted-average period of approximately 1.8 years.

As of December 31, 2006, 2005 and 2004, excess tax benefits, resulting
principally from stock options were $3.6 million, $3.9 million and $3.3 million,
respectively.

No stock options have been granted to officers and employees since February
2002. No stock options have been granted to non-employee directors since May
2003. Prior to these dates, the Company had granted stock options for the
purchase of its common stock to officers, certain key employees and non-employee
directors under two stockholder-approved plans. The exercise price of the stock
options was the fair value on the grant date, which was the date the Board of
Directors approved the respective grants. 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 stock options or other equity awards such as restricted stock,
restricted stock units or stock appreciation rights. The 1995 Non-Employee
Directors' Stock Plan authorizes the issuance of up to 300,000 shares of the
Company's common stock for equity awards. At December 31, 2006, there were
1,242,231 and 148,500 shares available for granting equity awards under the 1995
Executive Incentive Compensation Plan and the 1995 Non-Employee Directors' Stock
Plan, respectively. Generally, new shares are issued for exercised stock options
and treasury shares are issued for vested restricted stock units.

Options issued under the 1995 Executive Incentive Compensation Plan generally
vested and became exercisable one year following the date of grant except
options issued in 2002 generally vested and became exercisable two years
following the date of grant. Options issued under the 1995 Non-Employee

13. FINANCIAL INSTRUMENTS

OFF-BALANCE SHEET RISK
As collateral for the Company's performance and to insurers, the Company is
contingently liable under standby letters of credit, bonds and bank guarantees
in the amounts of $128.4 million and $154.0 million at December 31, 2006 and
2005, respectively. These standby letters of credit, bonds and bank guarantees
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 0.25 percent to 1.90 percent per annum of the instruments' face
value. If the Company were required to obtain replacement standby letters of
credit, bonds and bank guarantees as of December 31, 2006 for those currently
outstanding, it is the Company's opinion that the replacement costs would not
vary significantly from the present fee structure.

                                      -82-


The Company has currency exposures in approximately 45 countries. The Company's
primary foreign currency exposures during 2006 were in the United Kingdom,
members of the European Economic and Monetary Union, Brazil, Canada and South
Africa.

OFF-BALANCE SHEET RISK - THIRD PARTY GUARANTEES
In connection with the licensing of one of the Company's trade names and
providing certain management services (the furnishing of selected employees),
the Company guarantees the debt of certain third parties related to its
international operations. These guarantees are provided to enable the third
parties to obtain financing of their operations. The Company receives fees from
these operations, which are included as Services sales in the Company's
Consolidated Statements of Income. The revenue the Company recorded from these
entities was $2.2 million, $1.9 million and $1.0 million for the twelve months
ended December 31, 2006, 2005 and 2004, respectively. The guarantees are renewed
on an annual basis and the Company would only be required to perform under the
guarantees if the third parties default on their debt. The maximum potential
amount of future payments (undiscounted) related to these guarantees was $2.9
million at December 31, 2006 and 2005. There is no recognition of this potential
future payment in the accompanying financial statements as the Company believes
the potential for making these payments is remote. These guarantees were renewed
in June 2006, September 2006 and November 2006.

The Company provided an environmental indemnification for property that was sold
to a third party in 2006. The term of this guarantee is three years and the
Company would only be required to perform under the guarantee if an
environmental matter is discovered on the property. The Company is not aware of
any environmental issues related to the property. The maximum potential amount
of future payments (undiscounted) related to this guarantee is $0.2 million at
December 31, 2006. There is no recognition of this potential future payment in
the accompanying financial statements as the Company believes the potential for
making this payment is remote.

The Company provided an environmental indemnification for property that was sold
to a third party in 2006. The term of this guarantee is indefinite, and the
Company would only be required to perform under the guarantee if an
environmental matter is discovered on the property relating to the time the
Company owned the property. The Company is not aware of any environmental issues
related to this property. The maximum potential amount of future payments
(undiscounted) related to this guarantee is estimated to be $3.0 million at
December 31, 2006. There is no recognition of this potential future payment in
the accompanying financial statements as the Company believes the potential for
making this payment is remote.

The Company provides guarantees related to arrangements with certain customers
that include joint and several liability for actions for which the Company may
be partially at fault. The terms of these guarantees do not exceed four years
and the maximum amount of future payments (undiscounted) related to these
guarantees is $3.0 million per occurrence. This amount represents the Company's
self-insured maximum limitation. There is no specific recognition of potential
future payments in the accompanying financial statements as the Company is not
aware of any claims.

The Company provided a guarantee related to the payment of taxes for a product
line that was sold to a third party in 2005. The term of this guarantee is five
years, and the Company would only be required to perform under the guarantee if
taxes were not properly paid to the government while the Company owned the
product line in accordance with applicable statutes. The Company is not aware of
any instances of noncompliance related to these statutes. The maximum potential
amount of future payments (undiscounted) related to this guarantee is estimated
to be $1.3 million at December 31, 2006. There is no recognition of any
potential future payment in the accompanying financial statements as the Company
believes the potential for making this payment is remote.

The Company provided an environmental indemnification for property that was sold
to a third party in 2004. The term of this guarantee is seven years and the
Company would only be required to perform under the guarantee if an
environmental matter is discovered on the property relating to the time the
Company owned the property that was not known by the buyer at the date of sale.
The Company is not aware of any environmental issues related to this property.
The maximum potential amount of future payments (undiscounted) related to this
guarantee is $0.8 million at December 31, 2006 and 2005. There is no recognition
of this potential future payment in the accompanying financial statements as the
Company believes the potential for making this payment is remote.

Every three years, the Company requires a third party to review procedures and
record keeping related to the production of certain products. Commencing in
2004, the Company provided an indemnification for any costs incurred by the
third party resulting from an injury while these services are being provided to
the Company. In addition, the Company provided an indemnification for certain
costs resulting from an outside claim against the third party. The
indemnification is provided for as long as the Company is producing products
which meet the third party's specifications. At December 31, 2006 and 2005, the
maximum potential amount of future payments (undiscounted) related to this
guarantee is $3.0 million per occurrence. This amount represents the Company's
self-insured maximum

                                      -83-


limitation. There is no specific recognition of this potential future payment in
the accompanying financial statements as the Company is not aware of any claims.

Prior to the Company's acquisition of the business, Hunnebeck guaranteed certain
third party debt to leasing companies in connection with the sale of equipment.
The guarantees expire on January 1, 2007 and December 1, 2008. At December 31,
2006, the maximum potential amount of future payments (undiscounted) related to
these guarantees was $0.1 million. The Company would only be required to perform
under the guarantees if a customer defaulted on the lease payments. There is no
recognition of these potential future payments in the accompanying financial
statements as the Company believes the potential for making these payments is
remote.

Liabilities for the fair value of each of the guarantee instruments noted above
were recognized in accordance with FASB Interpretation No. 45, "Guarantor's
Accounting and Disclosure Requirements for Guarantees, Including Indirect
Guarantees of Indebtedness of Others" ("FIN 45"). These liabilities are included
in Other current liabilities or Other liabilities (as appropriate) on the
Consolidated Balance Sheets. The recognition of these liabilities did not have a
material impact on the Company's financial condition or results of operations
for the twelve months ended December 31, 2006 or 2005.

In the normal course of business, the Company provides legal indemnifications
related primarily to the performance of its products and services and patent and
trademark infringement of its goods and services sold. These indemnifications
generally relate to the performance (regarding function, not price) of the
respective goods or services and therefore no liability is recognized related to
the fair value of such guarantees.

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES
The Company has several hedges of net investment recorded in accordance with
SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities"
("SFAS 133"). The Company recorded a debit of $14.0 million and a credit of
$16.3 million during 2006 and 2005, respectively, in the foreign currency
translation adjustments line of Other comprehensive income (loss) related to
hedges of net investments.

At December 31, 2006 and 2005, the Company had $170.9 million and $157.9 million
contracted amounts, respectively, of foreign currency forward 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 outstanding at December 31, 2006 mature within six months and are with
major financial institutions. The Company may be 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 and does not expect
default by them. Foreign currency forward 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.

The following tables summarize by major currency the contractual amounts of the
Company's forward exchange contracts in U.S. dollars as of December 31, 2006 and
2005. The "Buy" amounts represent the U.S. dollar equivalent of commitments to
purchase foreign currencies, and the "Sell" amounts represent the U.S. dollar
equivalent of commitments to sell foreign currencies.

pounds sterling, euros, Canadian dollars, Australian dollars, Mexican pesos,
South African rands and Taiwan dollars which were used to offset certain future

thousand that was included in Other comprehensive income (loss), net of deferred
taxes, at December 31, 2006. The Company did not elect to treat the remaining
contracts as hedges under SFAS 133 and so mark-to-market gains and losses were
recognized in net income.

================================================================================

At December 31, 2005, the Company held forward exchange contracts in British
pounds sterling, euros, Canadian dollars and Taiwan dollars which were used to
offset certain future payments between the Company and its various subsidiaries,
vendors or customers. These contracts all mature by November 2006. The Company
had outstanding forward contracts designated as SFAS 133 cash flow hedges in the
amount of $6.1 million at December 31, 2005. These forward contracts had a net
unrealized loss of $112 thousand that was included in other comprehensive income
(loss), net of deferred taxes, at December 31, 2005. The Company did not elect
to treat the remaining contracts as hedges under SFAS 133 and so mark-to-market
gains and losses were recognized in net income.

CONCENTRATIONS OF CREDIT RISK
Financial instruments, which potentially subject the Company to concentrations
of credit risk, consist principally of cash and cash equivalents 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 generally
limited due to the Company's large number of customers and their dispersion
across different industries and geographies. However, the Company's Mill
Services Segment has several large customers throughout the world with
significant accounts receivable balances. In December 2005, the Company acquired
BISNH. This acquisition has increased the Company's corresponding concentration
of credit risk to customers in the steel industry. Additionally, consolidation
in the global steel industry has increased the Company's exposure to specific
customers. Additional consolidation is possible. Should transactions occur
involving some of the steel industry's larger companies, which are customers of
the Company, it would result in an increase in concentration of credit risk for
the Company.

The Company generally does not require collateral or other security to support
customer receivables. If a receivable from one or more of the Company's larger
customers becomes uncollectible, it could have a material effect on the
Company's results of operations and cash flows.

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

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

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

         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.

the Company in the United States and the United Kingdom exceeded 10% of
consolidated sales with 38% and 20%, respectively, in 2006; 42% and 20%,
respectively, in 2005; and 42% and 21%, respectively, in 2004. There are no
significant inter-segment sales.

No single customer represented 10% or more of the Company's sales in 2005 and
2004. However, one customer in the Mill Services Segment provided $351.0 million
in sales for 2006, which was 10% of the Company's revenues for the year. In
addition, the Mill Services Segment is dependent largely on the global steel
industry and in 2006, 2005 and 2004, there were two customers that each provided
in excess of 10% of this Segment's revenues under multiple long-term contracts
at several mill sites. The loss of any one of these contracts would not have a
material adverse impact upon the Company's financial position or cash flows;
however, it could have a material effect on quarterly or annual results of
operations. Additionally, these customers have significant accounts receivable
balances. Further consolidation in the global steel industry is probable. Should
transactions occur involving some of the Company's larger steel industry
customers, it would result in an increase in concentration of credit risk for
the Company.

Corporate assets include principally cash, insurance receivables, prepaid
pension costs and United States deferred income taxes. Net Property, Plant and
Equipment in the United States represented 30%, 33% and 34% of total Net
Property, Plant and Equipment as of December 31, 2006, 2005 and 2004,
respectively. Net Property, Plant and Equipment in the United Kingdom
represented 23% of total Net Property, Plant and Equipment as of December 31,
2006, 2005 and 2004.

Cash proceeds associated with these gains are included in Proceeds from the sale
of assets in the investing activities section of the Consolidated Statements of
Cash Flows.

IMPAIRED ASSET WRITE-DOWNS
Impairment losses are measured as the amount by which the carrying amount of
assets exceeded their fair value. Fair value is estimated based upon the
expected future realizable cash flows including anticipated selling prices. In
2006, the Company recorded an asset impairment loss of $4.2 million for certain
plant, property and equipment related to exiting an underperforming product line
in the Gas Technologies Segment.

Non-cash impaired asset write-downs are included in Other, net in the
Consolidated Statements of Cash Flows as adjustments to reconcile net income to
net cash provided by operating activities.

EMPLOYEE TERMINATION BENEFIT COSTS
The Company adopted SFAS No. 146, "Accounting for Costs Associated with Exit or
Disposal Activities," ("SFAS 146") on January 1, 2003. This standard addresses
involuntary termination costs associated with one-time benefit arrangements
provided as part of an exit or disposal activity. These costs and the related
liabilities are recognized by the Company when a formal plan for reorganization
is approved at the appropriate level of management and communicated to the
affected employees. Additionally, costs associated with on-going benefit
arrangements, or in certain countries where statutory requirements dictate a
minimum required benefit, are recognized when they are probable and estimable,
in accordance with SFAS No. 112, "Employers' Accounting for Postemployment
Benefits," (SFAS 112).

The total amount of employee termination benefit costs incurred for the years
2006, 2005 and 2004 was as follows. None of the actions are expected to incur
any additional costs.

Employee termination benefit costs incurred but not paid as of December 31 2006
totaled $1.9 million. The payments for employee termination benefit costs are
reflected as uses of operating cash in the Consolidated Statements of Cash
Flows.

COSTS ASSOCIATED WITH EXIT OR DISPOSAL ACTIVITIES
Costs associated with exit or disposal activities are recognized in accordance
with SFAS 146 and are included as a component of Other expenses in the Company's
Consolidated Statements of Income. SFAS 146 addresses involuntary termination
costs (as discussed above) and other costs associated with exit or disposal
activities (exit costs). Costs to terminate a contract that is not a capital
lease are recognized when an entity terminates the contract or when an entity
ceases using the right conveyed by the contract. This includes the costs to
terminate the contract before the end of its term or the costs that will
continue to be incurred under the contract for its remaining term without
economic benefit to the entity (e.g., lease run-out costs). Other costs
associated with exit or disposal activities (e.g., costs to consolidate or close
facilities and relocate equipment or employees) are recognized and measured at
their fair value in the period in which the liability is incurred. In 2006, $1.4
million of exit costs were incurred. These were principally relocation costs and
lease run-out costs for the Engineered Products and Services Category and the
Mill Services and Access Services Segments.

In 2005 and 2004, exit costs incurred were $1.0 million and $1.0 million,
respectively. These were principally lease run-out costs, lease termination
costs and relocation costs for the Mill Services and Access Services Segments
and the Engineered Products and Services Category.

          Schedules other than that listed above are omitted for the reason that
