                                     PART I
 
ITEM 1. BUSINESS
 
     SPX Corporation ("SPX" or the "company") is a global provider of industrial
products and services, technical products and systems, service solutions and
vehicle components. The company was organized in 1911 under the laws of
Michigan, and reincorporated in Delaware in 1968. It was known as The Piston
Ring Company until 1931, when it changed its name to Sealed Power Corporation.
The name was changed again in 1988, when it became SPX Corporation. Today, SPX
Corporation is a global company with operations in 19 countries. The worldwide
headquarters is located in Muskegon, Michigan.
 
     1998 was a year of dynamic change for SPX. Significant accomplishments in
1998 follow:
 
     -Completed the merger ("Merger") of SPX and General Signal Corporation
      ("GSX") on October 6, 1998 (the "Merger Date"). On an aggregate basis, GSX
      shareholders received 18.236 million shares of SPX common stock and $784.2
      in cash in exchange for all outstanding common stock of GSX. As former GSX
      shareholders owned approximately 60% of the company after the Merger and
      GSX was approximately twice the size of SPX, the Merger was accounted for
      as a reverse acquisition. GSX was considered the accounting acquirer and
      SPX was treated as the acquired company. The transaction was accounted for
      as a purchase business combination whereby the assets and liabilities of
      SPX were recorded at their fair market value as of the Merger Date. SPX
      takes on the financial history of the former GSX. Consequently, the
      company's 1998 operating results include the twelve months operating
      results of GSX on a historical cost basis and the three months operating
      results of the former SPX businesses based on their new fair market values
      assigned to the respective assets and liabilities. In accordance with
      reverse acquisition accounting, the historical financial statements of GSX
      have been adjusted to reflect common share data and earnings per share to
      SPX equivalent shares based on the 0.4186 share portion of the exchange
      ratio. The cash portion of the Merger consideration has been accounted for
      as a dividend to the GSX shareholders.
 
     -Obtained a new $1,650.0 financing facility, including a $250.0 Revolving
      Loan. Three term loans aggregating $1,400.0 funded various payments due
      upon the Merger, including the cash portion of the merger consideration
      and the refinancing of certain debt. See Note 14 to the consolidated
      financial statements for further discussion.
 
     -Closed the former GSX corporate offices during the fourth quarter of 1998
      and recorded a $69.3 charge primarily for Merger related change of control
      agreements (including purchase of GSX stock options and restricted shares)
      with former GSX corporate employees. This charge also included closing
      costs associated with the corporate facility. See Note 4 to the
      consolidated financial statements for further discussion.
 
     -Recorded a $32.4 restructuring charge in the fourth quarter of 1998 for
      costs to close 18 former GSX facilities and reduce net headcount by
      approximately 1,000 employees. See Note 4 to the consolidated financial
      statements for further discussion.
 
     -Received the Dual-Lite and Signaling businesses from EGS Electrical Group
      LLC ("EGS") on October 6, 1998 in a partial rescission of the original EGS
      venture formation in the third quarter of 1997. As a result of this
      transaction, the company's ownership in EGS was reduced from 47.5% to
      44.5%. In February of 1999, the company announced an agreement to sell the
      Dual-Lite business. This sale is anticipated to be completed by the end of
      the first quarter of 1999 and is subject to completion of due diligence
      and regulatory approval.
 
     -Prior to the Merger, SPX completed three acquisitions for an aggregate
      purchase price of $70.2 and GSX completed an acquisition at a purchase
      price of $10.9. These acquisitions expanded the company's presence in
      vehicle technical information services, vehicle diagnostic equipment,
      transmission repair kits and crystal growing furnaces.
 
     -Terminated the planned spin-off of Inrange Technologies and the possible
      disposition of three other units that had been announced by the former GSX
      management team in 1997.
 
                                        1
<PAGE>   3
 
     -Initiated the SPX Value Improvement Process(TM) at the former GSX
      businesses. The SPX Value Improvement Process represents an integrated,
      transferable approach to doing business that consists of six components
      executed concurrently. These include: implementation of Economic Value
      Added ("EVA(R)") in its full form; infusion of the SPX leadership
      standards throughout the organization; completion of the strategic review
      process to determine which businesses to fix, sell or grow; right size and
      consolidate; development of growth strategies; and driving the results
      expected by shareholders.
 
     Additionally, GSX completed several significant transactions in 1997 and
1996 as follows:
 
     -Sold General Signal Pump Group ("GSPG") in August 1997 for approximately
      $200.0 and recognized a pretax gain of $63.7, or $17.2 after-tax. Annual
      1996 sales of GSPG were approximately $201.0. In January 1996, the company
      sold Kinney Vacuum Company ("Kinney") for $29.0 and recorded a pretax gain
      of $20.8, or $12.5 after-tax. Annual 1995 sales of this business were
      approximately $25.0.
 
     -Contributed the net assets of General Signal Electrical Group ("GSEG") in
      September 1997 to a venture with Emerson Electric's Appleton Electric
      operations in exchange for a 47.5% interest in EGS. Annual 1996 sales of
      GSEG were approximately $294.0. The company accounts for its investment in
      EGS under the equity method of accounting.

SERVICE SOLUTIONS
 
     The Service Solutions segment includes operations that design, manufacture
and market a wide range of specialty service tools, equipment and services
primarily to the worldwide motor vehicle industry. The company has numerous
competitors that specialize in certain lines of its products and services. The

producer of electronic engine diagnostic equipment and emissions testing
 
                                        4
<PAGE>   6
 
equipment in North America and Europe. The key competitive factors influencing
the sale of specialty service tools are design expertise, timeliness of
delivery, quality, service and price. Sales of specialty service tools essential
to dealerships tend to vary with changes in vehicle design and the number of
dealerships and are not directly dependent on the volume of vehicles that are
produced by the motor vehicle manufacturers. Design of specialty service tools
is critical to their functionality and generally requires close coordination
with either the motor vehicle manufacturer or with the ultimate users of the
tools or instruments. These products are marketed as solutions to service
problems and as aids to performance improvements. After the design is completed,
the company manufactures, assembles or outsources these products. The company
also markets a broad line of equipment of other manufacturers through dealer
equipment programs coordinated with certain motor vehicle manufacturers and
aftermarket service organizations.
 
     This operation provides customers with essential program and general
specialty service tools, dealer equipment, owners manuals, service manuals,
training materials and other services. Customers include automotive, heavy duty,
agricultural and construction vehicle dealerships of motor vehicle
manufacturers. These products and services are sold or provided using the brands
and trade names of Kent-Moore, OTC, VL Churchill, Lowener OTC Tool, Dieseltune,
Miller Special Tools, Jurubatech, Brasch Tech Data, Dealer Equipment and
Services and, in some cases, the motor vehicle manufacturer's identity.
Essential program and general specialty service tools include specialty
hand-held mechanical tools and specialty hand-held electronic diagnostic
instruments and related software. These products are based on customer needs,
primarily to perform warranty and other service work at franchised dealers. The
division's technical product development and sales staff works closely with the
original equipment manufacturers to design tools to meet the exacting needs of
specialty repair work. Products are sold to franchised dealers under both
essential and general programs. Essential programs are those in which the motor
vehicle manufacturer requires its dealers to purchase and maintain the tools for
warranty and service work.
 
     This operation also provides the motor vehicle service aftermarket with a
wide range of specialty service tools. These products are marketed under the
name brands of Allen Testproducts, Bear, OTC, Robinair, Wheelforce and VL
Churchill. Certain of the products are marketed to dealers of motor vehicle
manufacturers. The division also markets a portion of its products to the
appliance, refrigeration and non-vehicular service repair market. Products
include specialized mechanical and electronic service tools, electronic
diagnostic equipment, refrigeration vacuum pumps, refrigerant recharging
equipment and leak detection equipment, refrigerant and engine coolant recovery
and recycling equipment, vehicle emissions testing equipment and shop equipment.
The operation distributes its products through warehouse distributors and
jobbers, a direct sales force, OEM distribution and independent distributorships
(primarily in foreign countries.) In-house sales and technical staffs support
these various types of distribution. In North America, the operation is
supported by a network of distribution and service centers.
 
     The operation also administers many dealer equipment programs in North
America. Under the motor vehicle manufacturer's identity, the division supplies
service equipment and support material to dealerships, develops and distributes
equipment catalogues and helps dealerships assess and meet their service
equipment needs.
 
VEHICLE COMPONENTS
 
     The company has a range of products for both original equipment
manufacturers and aftermarket customers. The Vehicle Components segment has
achieved various OEM customer quality recognition and awards and includes four
operations that design, manufacture and market component parts for light and
heavy duty vehicle markets. The component parts for the light and heavy duty
vehicle markets are comprised of two primary sectors: (i) the OEM sector and
(ii) the vehicle maintenance and repair sector (the replacement market or
aftermarket). The U.S. -- Canadian -- European OEM sector is composed primarily
of four classes of customers: (a) U.S. manufacturers; (b) foreign companies
producing vehicles in North America and Europe; (c) European vehicle
manufacturers, sometimes sourcing the company's products through assemblies; and
(d) vehicle manufacturers producing vehicles outside the U.S., Canada and
Europe. Aftermarket customers include the service organizations of OEMs,
automotive parts manufacturers and distributors and private brand distributors.

     In its main product areas, the company has a small number of principal
competitors (including the OEMs in certain product categories), some of which
are larger in size and have greater financial resources than the company.
Competitive factors influencing sales include quality, technology, service and
price.
 
          Solenoid Valves -- The company produces solenoid valves and related
     assemblies for major vehicle and transmission manufacturers around the
     world. The company's proprietary solenoid valve products interface between
     the electronic signals of a vehicle's on-board computer and the vehicle's
     hydraulic systems. The company uses this technology to design and
     manufacture solenoid valves for electronically controlled automatic
     transmissions. Products are sold almost exclusively to automotive OEMs
     through marketing and sales personnel who are assisted by an outside sales
     organization. The market is driven primarily by major OEM model and
     assembly programs.
 
          Precision Die-castings -- The company produces precision aluminum and
     magnesium die-cast parts for automotive steering systems, and other
     assorted automotive/light truck uses. Primary products in this area include
     steering column parts, rack-and-pinion components and other castings such
     as components for fuel systems, clutches and transmissions. Products are
     sold almost exclusively to automotive OEMs through marketing and sales
     personnel who are assisted by an outside sales organization. The market is
     driven primarily by major OEM model and assembly programs.
 
          Filtration Products -- The company is a leading producer of automatic
     transmission filters, transmission kits and other filter products and has a
     leading position in the U.S. and Canadian OEM market and aftermarket. A
     typical transmission filter product consists of a composite plastic/metal
     or all metal housing which contains a highly specialized non-woven felt,
     polymesh, or metal screen filter element designed to capture foreign
     particles. The company sells filters directly to the worldwide OEM market
     and aftermarket. Sales to the aftermarket include the OEM parts and service
     organizations as well as private brand manufacturers and assorted
     transmission rebuilders and repackagers. The company also participates in
     the worldwide OEM market. In Europe, the company's 60% owned joint venture,
     IBS Filtran, manufactures and distributes filters to OEM customers. In the
     Pacific Rim, the division exports filters to OEM manufacturers in Japan,
     Korea and Australia.
 
          Cold-Forged Components -- The company is a manufacturer of cold-forged
     solid and tubular metal components and assemblies for the vehicle market.
     Products include cold-forged vehicle steering and suspension parts and
     cold-forged cranks for bicycles. The products are marketed principally to
     the OEM market through a direct sales force.
 
EGS ELECTRICAL GROUP LLC
 
     The company owns 44.5% of EGS, a company which produces electrical
fittings, hazardous location lighting, emergency lighting, power conditioning
products and signaling products.
 
INTERNATIONAL OPERATIONS
 
     The company has wholly owned operations located in Australia, Austria,
Brazil, Canada, China, France, Germany, India, Ireland, Italy, Japan, Mexico,
The Netherlands, Singapore, Spain, Switzerland, Taiwan and the United Kingdom.
The company has an 80% interest in JATEK, a Japanese company that sells various
products into the Asian market, including many of the company's specialty
service tool products, and a 60% interest in IBS Filtran, a German company that
manufacturers and distributes automotive transmission filters to the European
market.
 
     The company's international operations are subject to the risk of possible
currency devaluation and blockage, nationalization or restrictive legislation
regulating foreign investments and other risks attendant to the countries in
which they are located.

RESEARCH AND DEVELOPMENT
 
     The company is actively engaged in research and development programs
designed to improve existing products and manufacturing methods and to develop
new products. These engineering efforts encompass all of the company's products
with divisional engineering teams coordinating their resources. Particular
emphasis has been placed on the development of new products that are compatible
with, and build upon, the manufacturing and marketing capabilities of the
company.
 
     The company spent approximately $73.4 million on research activities
relating to the development and improvement of its products in 1998, $45.7
million in 1997 and $47.5 million in 1996.
 
PATENTS/TRADEMARKS
 
     The company owns numerous domestic and foreign patents covering a variety
of its products and manufacturing methods and owns a number of registered
trademarks. Although in the aggregate its patents and trademarks are of
considerable importance in the operation of its businesses, the company does not
consider any single patent or trademark to be of such material importance that
its absence would adversely affect the company's ability to conduct its
businesses as presently constituted. The company is both a licensor and licensee
of patents. See Note 16 to the consolidated financial statements for further
discussion.
 
RAW MATERIALS
 
     The company manufactures many of the components used in its products. It
also purchases a variety of basic materials and component parts. The company
believes that it will generally be able to obtain adequate supplies of major
items or reasonable substitutes at reasonable costs.
 
COMPETITION
 
     Although the businesses of the company are highly competitive, the
competitive position cannot be determined accurately in the aggregate or by
segment since none of its competitors offer all of the same product lines or
serve all of the same markets, nor are reliable comparative figures available
for many of its competitors. In most product groups, competition comes from
numerous concerns, both large and small. The principal methods of competition
are price, service, product performance and technical innovation. These methods
vary with the type of product sold. The company believes that it can compete
effectively on the basis of each of these factors as they apply to the various
products offered.
 
ENVIRONMENTAL MATTERS
 
     Note 16, Commitments and Contingent Liabilities, to the Consolidated
Financial Statements is hereby incorporated by reference.
 
EMPLOYMENT
 
     At December 31, 1998, the company had approximately 14,000 employees.
Approximately 1,500 employees are represented by 13 different collective
bargaining units. Approximately 39% of the labor force
 
                                        7
<PAGE>   9
 
that is covered by collective bargaining agreements have agreements that expire
within one year. The company has generally experienced satisfactory labor
relations at its various locations.
 
OTHER MATTERS
 
     No customer or group of customers under common control accounted for more
than 10% of consolidated sales.
 
     No single line of business or product line accounted for more than 10% of
consolidated sales.
 
     All of the company's businesses are required to maintain sufficient levels
of working capital to support customer requirements, particularly inventory.
Sales terms and payment terms are in line with the practices of the industries
in which they compete, none of which are unusual.
 
     The majority of the company's businesses tend to be nonseasonal and closely
follow changes in the industrial and motor vehicle markets, and in general
economic conditions.

     In addition to manufacturing plants, the company, as a lessee, occupies
executive offices in Muskegon, Michigan and various sales and service locations
throughout the world. All of these properties, as well as the related machinery
and equipment, are considered to be well maintained, suitable and adequate for
their intended purposes. Virtually all of these assets are collateral in the
company's debt agreements. See Note 14 to the consolidated financial statements
for further discussion. Various facilities included above, including the Former
GSX corporate headquarters, have been or will be affected (sold, sublet, vacated
or closed) pursuant to the restructuring initiatives which the company began in

     During the second quarter of 1997, SPX eliminated quarterly cash dividends
and stated that future distributions to shareholders would be in the form of
open market purchases of common stock when deemed appropriate by management. GSX
discontinued paying dividends as of the Merger announcement in July 1998.
 
     The approximate number of shareholders of record of the company's common
stock as of December 31, 1998 was 9,000.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS
        (DOLLARS IN MILLIONS, EXCEPT PER-SHARE DATA)
 
     The following should be read in conjunction with the company's consolidated
financial statements and the related notes.
 
  Significant Events and Initiatives
 
     1998 was a year of dynamic change for SPX Corporation ("SPX" or the
"company"). Significant accomplishments in 1998 follow:
 
     - Completed the merger ("Merger") of SPX and General Signal Corporation
       ("GSX") on October 6, 1998 (the "Merger Date"). On an aggregate basis,
       GSX shareholders received 18.236 million shares of SPX common stock and
       $784.2 in cash in exchange for all outstanding common stock of GSX. As
       former GSX shareholders owned approximately 60% of the company after the
       Merger and GSX was approximately twice the size of SPX, the Merger was
       accounted for as a reverse acquisition. GSX was considered the accounting
       acquirer and SPX was treated as the acquired company. The transaction was
       accounted for as a purchase business combination whereby the assets and
       liabilities of SPX were recorded at their fair market value as of the
       Merger Date. SPX takes on the financial history of the former GSX.
       Consequently, the company's 1998 operating results include the twelve
       months operating results of GSX on a historical cost basis and the three
       months operating results of the former SPX businesses based on their new
       fair market values assigned to the respective assets and liabilities. In
       accordance with reverse acquisition accounting, the historical financial
       statements of GSX have been adjusted to reflect common share data and
       earnings per share to SPX equivalent shares based on the 0.4186 share
       portion of the exchange ratio. The cash portion of the Merger
       consideration has been accounted for as a dividend to the GSX
       shareholders.
 
     - Obtained a new $1,650.0 financing facility, including a $250.0 Revolving
       Loan. Three term loans aggregating $1,400.0 funded various payments due
       upon the Merger, including the cash portion of the merger consideration
       and the refinancing of certain debt. See Note 14 to the consolidated
       financial statements for further discussion.
 
     - Closed the former GSX corporate offices during the fourth quarter of 1998
       and recorded a $69.3 charge primarily for Merger related change of
       control agreements (including purchase of GSX stock options and
       restricted shares) with former GSX corporate employees. This charge also
       included closing costs associated with the corporate facility. See Note 4
       to the consolidated financial statements for further discussion.
 
     - Recorded a $32.4 restructuring charge in the fourth quarter of 1998 for
       costs to close 18 former GSX facilities and reduce net headcount by
       approximately 1,000 employees. See Note 4 to the consolidated financial
       statements for further discussion.
 
     - Received the Dual-Lite and Signaling businesses from EGS Electrical Group
       LLC ("EGS") on October 6, 1998 in a partial rescission of the original
       EGS venture formation in the third quarter of 1997. As a result of this
       transaction, the company's ownership in EGS was reduced from 47.5% to
       44.5%. In February of 1999, the company announced an agreement to sell
       the Dual-Lite business. This sale is anticipated to be completed by the
       end of the first quarter of 1999 and is subject to completion of due
       diligence and regulatory approval.
 
     - Prior to the Merger, SPX completed three acquisitions for an aggregate
       purchase price of $70.2 and GSX completed an acquisition at a purchase
       price of $10.9. These acquisitions expanded the company's presence in
       vehicle technical information services, vehicle diagnostic equipment,
       transmission repair kits and crystal growing furnaces.
 
     - Terminated the planned spin-off of Inrange Technologies and the possible
       disposition of three other units that had been announced by the former
       GSX management team in 1997.
 
                                       13
<PAGE>   15
 
     - Initiated the SPX Value Improvement Process(TM) at the former GSX
       businesses. The SPX Value Improvement Process represents an integrated,
       transferable approach to doing business that consists of six components
       executed concurrently. These include: implementation of Economic Value
       Added ("EVA(R)") in its full form; infusion of the SPX leadership
       standards throughout the organization; completion of the strategic review
       process to determine which businesses to fix, sell or grow; right size
       and consolidate; development of growth strategies; and driving the
       results expected by shareholders.
 
     Additionally, GSX completed several significant transactions in 1997 and
1996 as follows:
 
     - Sold General Signal Pump Group ("GSPG") in August 1997 for approximately
       $200.0 and recognized a pretax gain of $63.7, or $17.2 after-tax. Annual
       1996 sales of GSPG were approximately $201.0. In January 1996, the
       company sold Kinney Vacuum Company ("Kinney") for $29.0 and recorded a
       pretax gain of $20.8, or $12.5 after-tax. Annual 1995 sales of this
       business were approximately $25.0.
 
     - Contributed the net assets of General Signal Electrical Group ("GSEG") in
       September 1997 to a venture with Emerson Electric's Appleton Electric
       operations in exchange for a 47.5% interest in EGS. Annual 1996 sales of
       GSEG were approximately $294.0. The company accounts for its investment
       in EGS under the equity method of accounting.

</TABLE>
 
     Revenues -- 1998 revenues decreased $129.2, or 6.6%, from 1997, primarily
due to the disposition of GSPG and the contribution of GSEG to EGS in the third
quarter of 1997. 1997 revenues included $353.1 for these two units. Mitigating
this loss of revenues was the Merger at the beginning of the fourth quarter of
1998 that added $237.2 of revenues in 1998. Adjusted for these transactions,
revenues decreased approximately 1%. 1997 revenues decreased 5.3% from 1996
primarily due to the disposition of GSPG and the contribution of GSEG to EGS.
Adjusted for these transactions, revenues increased approximately 2%. 1999
revenues are expected to increase to approximately $2.6 billion with the
inclusion of SPX operations for a full year and are anticipated to show modest
growth on an aggregate basis compared to pro forma 1998 revenues.
 
     Gross margin -- In 1998, gross margin decreased to 30.3% from 32.8% in
1997. The 1998 gross margin decrease was primarily due to $36.5 of environmental
charges related to the Merger and restructuring actions
 
                                       14
<PAGE>   16
 
and $23.9 of other Merger and restructuring related expenses recorded at certain
divisions. 1997 gross margin decreased from 1996 due to a shift in revenues to
lower margin products in certain businesses.
 
     Selling, general and administrative expense ("SG&A") -- SG&A in 1998
increased to $471.8, or 25.8% of revenues. The $471.8 included $5.8 of various
integration costs for combining SPX and GSX, a $9.0 in-process technology charge
from the valuation of SPX for purchase accounting, $19.5 to write down goodwill
of a business held for sale to net realizable value, and $8.0 of other Merger
and restructuring related expenses recorded at certain divisions. Excluding the
impact of these one-time charges, 1998 SG&A as a percentage of revenues was
comparable to the percentages in 1997 and 1996.
 
     Goodwill/intangible amortization -- Amortization in 1998 increased
approximately $7.3 as a result of the Merger. Otherwise, 1998 and 1997
amortization was lower than the prior year due to the disposition of GSPG and
the contribution of GSEG to EGS in late 1997.
 
     Special charges -- The company recorded special charges of $101.7 in 1998,
which included $69.3 of costs associated with closing the former GSX corporate
office and $32.4 of restructuring costs related to the Merger and integration of
the GSX operations. See Note 4 to the consolidated financial statements for
further discussion.
 
     Other expense (income), net -- 1997 includes a $63.7 gain on the sale of
GSPG and $9.0 gain on the sale of an equity interest in a Mexican company. In
1996, the company recorded a $20.8 gain on the sale of Kinney.
 
     Interest expense, net -- Increased significantly in 1998 over 1997 due to
increased debt incurred on the Merger Date as a result of the merger of SPX and
GSX. Interest expense in 1997 decreased significantly from 1996 due to lower
average debt levels.
 
     Income taxes -- The company's effective tax rate from continuing operations
was (7.1)%, 48.2%, and 40.0% in 1998, 1997 and 1996, respectively. The
difference between these rates and the statutory rate is primarily due to
non-deductible goodwill amortization and other non-deductible expenses related
to business divestitures. The company anticipates that its effective income tax
rate for 1999 will be approximately 40.5%.
 
     Capital expenditures -- Capital expenditures in 1998 were higher than 1997
and 1996 primarily due to the Merger. A significant portion of the expenditures
were for new business information systems. In 1999, the company anticipates
capital expenditures will be approximately $100.0.
 
     Total assets -- Total assets increased in 1998 as a result of the Merger.
Approximately $1,500 of total assets were acquired in the Merger. Total assets
in 1997 decreased from 1996 due to the disposition of GSPG and the contribution
of GSEG to EGS.

INDUSTRIAL PRODUCTS AND SERVICES
 
     Revenues for 1998 decreased $374.9 from 1997 which included the revenues of
GSPG and GSEG. Revenues of these units were $353.1 in 1997. Revenues for 1998
included $15.3 from the Merger. Excluding these transactions, revenues decreased
$37.1 in 1998 reflecting overall weakness in sales of industrial mixers, motors
and ovens. The decrease in 1997 revenues from 1996 reflects GSPG and GSEG sales
of $353.1 in 1997 compared to $494.4 in 1996.
 
     The company expects 1999 revenues to be relatively stable with modest
growth over 1998.
 
     Operating Income in 1998 was significantly impacted by the divestiture of
GSPG and GSEG, $16.3 of restructuring charges and $10.5 of other Merger and
restructuring related costs included in cost of sales and SG&A. Operating income
in 1997 decreased from 1996 principally due to the divestiture of GSPG and GSEG
and unusual charges of $1.9 related primarily to asset write downs and lease
termination costs. 1996 was impacted by unusual charges of $11.9 related to
asset write downs, lease termination costs, warranty and other costs offset by
insurance proceeds related to equipment destroyed in a fire. Operating income in
1999 is expected to improve over 1998 due to higher revenues, lower one-time
costs and savings associated with the restructuring initiatives.
 
TECHNICAL PRODUCTS AND SYSTEMS
 
     Revenues for 1998 were up $37.1, or 5.4%, over 1997. This increase was due
to higher revenues in data networking equipment, broadcast antenna systems, and
fire detection products, offset by lower sales of uninterruptible power systems
and crystal growing furnaces. Revenues for 1997 and 1996 were flat reflecting
the continuing softness in sales of uninterruptible power supply equipment and
crystal growing furnaces.
 
     The company expects 1999 revenues to modestly increase due to continuing
demand for broadcast antenna systems and fire detection products and recovery in
demand for uninterruptible power supply equipment and crystal growing furnaces.
 
     Operating Income in 1998 of $24.0 was impacted by $14.5 of restructuring
charges and $18.8 of other Merger and restructuring related costs included in
cost of sales and SG&A. Operating income in 1997 was negatively impacted by
$20.0 of expenses for asset valuations, lease termination costs and other
matters. Operating income in 1996 was impacted by unusual charges of $1.8
related to asset write downs offset by royalty income.
 
     Operating income in 1999 is expected to improve over 1998 due to higher
revenues, lower one-time costs and savings associated with the restructuring
initiatives.
 
SERVICE SOLUTIONS
 
     Revenues for 1998 reflect the results of SPX's Service Solution segment
since the Merger Date. Revenues were comparable to pro forma revenue for the
same period in 1997.
 
     1998 pro forma revenues were approximately $610.0. 1999 revenues are
anticipated to grow 5% to 10% over 1998 pro forma. This increase reflects
continuing strength in the segment's product lines and acquisitions completed in
mid-1998.
 
     Operating Income in 1998 of $12.8 included approximately $3.7 in
incremental goodwill and intangible amortization resulting from the purchase
accounting for SPX.
 
     Operating income in 1999 for this segment is expected to improve over 1998,
due to the inclusion of the SPX businesses for a full year in 1999.
 
VEHICLE COMPONENTS
 
     Revenues for 1998 were up principally from the addition of the SPX Vehicle
Components businesses that, subsequent to the Merger, added $64.9 of revenues.
Excluding the impact of the Merger, 1998 revenues were down $13.3 from 1997
principally reflecting the mid-year strike at General Motors.
                                       16
<PAGE>   18
 
     1999 revenues will include the SPX businesses for a full year and
accordingly, should increase significantly over 1998. Additionally, the company
has been awarded new contracts with an original equipment manufacturer that will
begin in late 1999 and ramp up in 2000.
 
     Operating Income in 1998 of $25.6 included the impact of the Merger of
offset by the impact of the General Motors strike, $1.6 of restructuring charges
and $2.6 of other Merger and restructuring related charges included in the cost
of sales and SG&A and approximately $2.3 in incremental goodwill and intangible
amortization resulting from the purchase accounting for SPX. Operating income in
1997 was up, in line with the increased revenues in 1997 over 1996. Operating
income in 1999 is expected to improve over 1998 due to the inclusion of SPX
businesses for a full year and lower one-time costs.
 
GENERAL CORPORATE EXPENSES
 
     The 1998 expense included the former GSX corporate office for the full year
and the SPX corporate office for the fourth quarter of 1998. Additionally, 1998
included $69.3 of special charges associated with closing the former GSX
corporate headquarters, $5.8 of various integration costs for combining SPX and
GSX, $36.5 of environmental charges related to the Merger and restructuring
actions, a $9.0 in-process technology charge from the valuation of SPX for
purchase accounting, and $19.5 to write down goodwill of a business held for
sale to net realizable value. 1997 and 1996 reflect the GSX corporate office
expenses only. In 1997, unusual gains of $4.0, net, were recorded to settle
patent litigation and the sale of related patents and other matters.
 
     The company expects 1999 general corporate expenses to approximate $30.0 to
$35.0 which reflects one corporate headquarters.

     1998 operating cash flow of $44.9 was negatively impacted by payments of
GSX corporate headquarters change of control obligations and other restructuring
related payments.
 
     Cash flow from investing activities in 1998 reflected capital expenditures
of $69.2 that included computer system upgrades at several operating units and
the inclusion of SPX capital expenditures in the fourth quarter. Cash flow from
investing activities for 1998 also included an expenditure of $10.9 for a
business acquisition. Cash inflows included $10.5 of the cash acquired in the
Merger and $15.5 of distributions received from EGS during the year. The company
anticipates capital expenditures in 1999 to be approximately $100.0.
 
     Cash flow from investing activities in 1997 included capital expenditures
of $56.5 and an outlay of $11.0 for a business acquisition. Additionally, 1997
included $216.9 of cash proceeds from the sale of GSPG and the sale of the
company's equity interest in a company in Mexico.
 
     Cash flow from financing activities in 1998 principally reflects the
refinancing of the company to accomplish the Merger and the related special
dividend payment of $784.2. Additionally, the company purchased $160.2 of common
stock in 1998 primarily as part of a buy-back program initiated in 1997.
Finally, cash flow from financing activities in 1998 included $36.5 in quarterly
dividend payments. As of July 1998, the date the Merger was announced, GSX
discontinued quarterly dividend payments.

     Cash flow from financing activities in 1997 included $51.7 in quarterly
dividend payments, the purchase of $240.4 of common stock as part of a buy-back
program initiated in 1996, and net debt borrowings of $52.4.
 
     On December 12, 1996, the company called for the redemption of its $100.0,
5.75% convertible subordinated notes. As of December 31, 1996, notes with a face
value of $57.4 had been converted into 1.5 million shares of GSX common stock
(before adjustment for the Merger), with an additional $39.3 converted into 1.0
million shares of GSX's common stock (before adjustment for the Merger), on
January 2, 1997. The balance of the notes was redeemed for cash in early 1997.
 
  Debt
 
     The company obtained a new $1,650.0 financing facility ("New Credit
Facility") to consummate the Merger, including a $250.0 Revolving Loan and three
term loans aggregating $1,400.0. See Note 14 to the consolidated financial
statements for further discussion.
 
     The following summarizes the debt outstanding and unused credit
availability, as of December 31, 1998:

(1)  Decreased by $56.3 of letters of credit outstanding under the facility at
     December 31, 1998, which reduce the unused credit availability.
 
     The New Credit Facility is secured by substantially all of the assets of
the company (excluding EGS) and requires the company to maintain certain
leverage and interest coverage ratios. The New Credit Facility also requires
compliance with certain operating covenants which limit, among other things, the
incurrence of additional indebtedness by the company and its subsidiaries, sales
of assets, the distribution of dividends, capital expenditures, mergers,
acquisitions and dissolutions. Under the most restrictive of the financial
covenants, the company was required to maintain (as defined) a maximum debt to
earnings before income taxes, depreciation and amortization ratio and a minimum
interest coverage ratio beginning in March 1999 and becoming more restrictive
thereafter.
 
     Management believes that cash flow from operations and the New Credit
Facility will be sufficient to meet operating cash needs, including working
capital requirements, capital expenditures and cash payments related to
restructuring initiatives for 1999. Aggregate future maturities of total debt
are $49.1 in 1999. Net interest expense will approximate $120.0 in 1999. In
2000, the $200.0 Interim Loan becomes due and the company believes that cash
flow from operations, proceeds from certain asset dispositions and the Revolving
Loan will be sufficient to service these obligations.
 
FACTORS THAT MAY AFFECT FUTURE RESULTS
 
     General Business Conditions -- The company operates within the industrial
and motor vehicle industries and future results may be affected by a number of
factors including industry conditions and economic conditions principally in the
U.S. and Europe. The majority of the company's revenues are not subject to
seasonal variation. Revenues within the Industrial Products and Services segment
generally follow the demand for capital goods orders. Revenues within the
Technical Products and Systems segment depend upon several
 
                                       18
<PAGE>   20
 
markets, principally the nonresidential construction, computer equipment and
telecommunication industries. Revenues within the Service Solutions segment are
dependent upon new vehicle introductions, environmental regulations, and the
general economic status of motor vehicle dealerships and aftermarket repair
facilities. Revenues within the Vehicle Components segment are predominantly
dependent upon domestic and foreign motor vehicle production.
 
     Special Charges -- The company continues to assess the former GSX
operations and expects that further restructuring charges will occur during
1999. These charges, which cannot now be quantified fully, could range from
$25.0 to $35.0, and would be recognized in the period in which such charges
occur. Additionally, 1999 will include an estimated $10.0 of incremental costs
associated with restructuring actions initiated in the fourth quarter of 1998.
These incremental costs did not qualify for recognition in 1998 and will be
expensed as incurred.
 
     Acquisitions and Divestitures -- The company continually reviews each of
its businesses pursuant to its "fix, sell or grow" strategy. These reviews could
result in selected acquisitions to expand an existing business or result in the
disposition of an existing business. Additionally, management has expressed that
it would consider a larger acquisition, more than $1 billion in revenues, if
certain criteria are met.
 
     Readiness for Year 2000  -- The company utilizes software and related
computer technology essential to its operations and to certain products that use
two digits rather than four to specify the year, which could result in a date
recognition problem with the transition to the year 2000. In 1997, the company
established a plan, utilizing both internal and external resources, to assess
the potential impact of the year 2000 problem on its systems, including embedded
technology, and operations and to implement solutions to address this issue. The
company has completed the assessment phase of its year 2000 plan, and is
continuing to survey its suppliers and service providers for year 2000
compliance. The company is in the renovation stage of its year 2000 plan and has
substantially completed the correction of many critical systems. The target
completion date of certain other critical systems is June 30, 1999. Third party
compliance and other factors could adversely affect these target dates. The
company does not believe the cost to remediate software and computer
technologies for the year 2000 problem will exceed $5.0 in 1999 and $10.0 in
total, which does not include costs to replace certain existing enterprise
resource planning systems. The company is in the process of implementing such a
new system across several of its businesses. The company estimates that it will
spend approximately $25 in 1999 to acquire and install this new system. There
can be no assurances that the costs of remediation and testing will not be
material. Moreover, there can be no assurances that the company will not
experience material unanticipated costs and/or business interruption due to year
2000 problems in its products, its internal systems, its supply chain or from
customer product migration issues. Based upon currently available information,
the company believes that the greatest risk associated with the year 2000
problem relates to compliance of third parties including, but not limited to,
electrical power and other utilities. A worst case scenario could result in
business interruptions, which could have a material effect on the company's
operations. The company has sent correspondence to all of its key suppliers in
assessing third party compliance as part of its year 2000 plan. The company is
developing contingency plans to mitigate the risks associated with the year 2000
problem and expects to complete these plans by July 1999. The statements set
forth in the foregoing paragraph are year 2000 readiness disclosures (as defined
under the Year 2000 Information and Readiness Act) and shall be treated as such
for all purposes permissible under such Act.
 
     Potential Volatility of Stock Price -- The market price of SPX's common
stock has been, and could be subject to wide fluctuations in response to, among
other things, quarterly fluctuations in operating results, acquisitions and
divestitures, failure to achieve published estimates of, or changes in earnings
estimates by securities analysts, announcements of new products or services by
competitors, sales of common stock by existing holders, loss of key personnel
and market conditions in the industry.
 
     Environmental and Legal Exposure -- The company's operations and properties
are subject to various regulatory requirements relating to environmental
protection. It is the company's policy to comply fully with applicable
environmental requirements. Also from time to time, the company becomes involved
in lawsuits arising from various commercial matters, including but not limited
to competitive issues, contract issues, intellectual property matters, workers'
compensation and product liability.
 
                                       19
<PAGE>   21
 
     The company maintains property, cargo, auto, product, general liability and
directors' and officers' liability insurance to protect itself against potential
loss exposures. There can be no assurance that such costs for environmental and
legal exposures could not have a material adverse effect on the company's
results of operations or financial position in the future.
 
     Pending Patent Litigation -- The company believes that it should ultimately
prevail on a pending patent infringement lawsuit which could result in a
significant judgement favorable to the company. However, since the amount of the
damages cannot be fully quantified until the legal discovery process proceeds
further and no assurances can be made as to the final timing and outcome of any
litigation, no gain has been recorded. See Note 16 to the consolidated financial
statements for further discussion.
 
     International Operations -- The company is increasing its sales outside the
United States which exposes the company to a number of risks including
unexpected changes in regulatory requirements and tariffs, possible difficulties
in enforcing agreements, longer payment cycles, exchange rate fluctuations,
difficulties in obtaining export licenses, and the possible imposition or
changing of income, withholding or other taxes, embargoes, exchange controls and
the adoption of other restrictions on foreign trade. Should any of these risks
occur, they may have a material adverse impact on the operating results of the
company.
 
     Impact of Inflation -- The company believes that inflation has not had a
significant impact on operations during the period 1996 through 1998.
 
     Significance of Goodwill -- The company had goodwill of $1,004.4 and
shareholders' equity of $390.5 at December 31, 1998. There can be no assurance
that circumstances will not change in the future that will affect the useful
life or carrying value of the company's goodwill. See Note 1 to the consolidated
financial statements for further discussion.
 
     EVA Incentive Compensation -- The company utilizes a measure known as
Economic Value Added ("EVA") for its incentive compensation plans. EVA is
internally computed by the company based on Net Operating Profit After-tax less
a charge on the capital invested in the company. These computations use certain
assumptions that vary from generally accepted accounting principles ("GAAP").
EVA is not a measure under GAAP and is not intended to be used as an alternative
to net income and measuring operating performance presented in accordance with
GAAP. The company believes that EVA, as internally computed, does represent a
strong correlation to the ultimate returns of the company's shareholders. Annual
incentive compensation expense is dependent upon the annual change in EVA,
relative to preestablished improvement targets and the expense can vary
significantly.
 
     Accounting Pronouncements -- Statement of Position 98-1 "Accounting for
Computer Software Developed for or Obtained for Internal Use" ("SOP 98-1")
provides guidance for accounting for software developed for internal use. The
company is required to adopt SOP 98-1 in 1999 and management believes such
adoption will not have a material effect on the company's results of operations
and financial position.
 
     Statement of Financial Accounting Standards ("SFAS") No. 133 "Accounting
for Derivative Instruments and Hedging Activities," which will become effective
January 2000, establishes accounting and reporting standards for derivative
instruments and hedging contracts. It also requires all derivatives to be
recognized as either assets or liabilities in the balance sheet at fair value
and changes in fair value to be recognized in income. Management is currently
analyzing the impact of this statement, but does not anticipate that the effect
on the company's results of operations and financial position will be material.
 
ADDITIONAL ITEM. SAFE HARBOR FOR FORWARD LOOKING STATEMENTS
 
     The company or its representatives from time to time may make or may have
made certain forward looking statements, orally or in writing, including without
limitation any such statements made or to be made in the Management's Discussion
and Analysis of Financial Condition and Results of Operations contained in
various SEC filings. The company wishes to ensure that such statements are
accompanied by meaningful cautionary statements, so as to ensure to the fullest
extent possible the protections of the safe harbor established in the Private
Securities Litigation Reform Act of 1995. Accordingly, such statements are
qualified in their entirety by reference to factors discussed under the caption
"Factors That May Affect Future
                                       20
<PAGE>   22
 
Results" in "Management's Discussion and Analysis of Financial Condition and
Results of Operations" of this filing, which could cause results to differ
materially from those projected in such forward looking statements.
 
     The company cautions the reader that these risk factors may not be
exhaustive. The company operates in a continually changing business environment,
and new risk factors emerge from time to time. Management cannot predict such
risk factors, nor can it assess the impact, if any, of such risk factors on the
company's business or the extent to which any factors, or combination of
factors, may cause actual results to differ materially from those projected in
any forward looking statements. Accordingly, forward looking statements should
not be relied upon as a prediction of actual results. In addition, management's
estimates of future operating results are based on the current compliment of
businesses, which is constantly subject to change as management implements its
fix, sell or grow strategy.
 
ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
 
     The company is exposed to market risk related to changes in interest rates
and foreign currency exchange rates, and selectively uses financial instruments
to manage these risks. The company does not enter into financial instruments for
speculative or trading purposes. The company has interest rate protection
agreements with financial institutions to limit exposure to interest rate
volatility. Additionally, the company enters into foreign currency forward or
option contracts to mitigate the risks of doing business in foreign currencies.
The company hedges currency exposures of firm commitments and specific assets
and liabilities denominated in non-functional currencies to protect against the
possibility of diminished cash flow and adverse impact on earnings. The
company's currency exposures vary, but are primarily concentrated in the
Canadian dollar, British pound, German mark, Japanese yen, Italian lira and
Singapore dollar. Translation exposures generally are not specifically hedged.
 
     The following table provides information, as of December 31, 1998, about
the company's outstanding debt obligations and presents principal cash flows,
weighted average interest rates by expected maturity dates and fair values. The
weighted-average interest rates used for variable rate obligations are based on
the rates in effect at December 31, 1998.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Shareholders and Board of Directors of
  SPX Corporation:
 
     We have audited the accompanying consolidated balance sheet of SPX
CORPORATION (a Delaware corporation) AND SUBSIDIARIES as of December 31, 1998,
and the related statements of income and comprehensive income, shareholders'
equity, and cash flows for the year then ended. These financial statements are
the responsibility of the company's management. Our responsibility is to express
an opinion on these financial statements based on our audit. We did not audit
the financial statements of EGS, the investment in which is reflected in the
accompanying financial statements using the equity method of accounting (see
Note 10). The statements of EGS were audited by other auditors whose report has
been furnished to us and our opinion, insofar as it relates to the amounts
included for EGS, is based solely on the report of the other auditors. The
financial statements of the company as of December 31, 1997 and 1996, were
audited by other auditors whose report dated January 23, 1998 (updated for
certain matters as to which the date is February 15, 1999) included an
explanatory paragraph with respect to the change in the company's method of
accounting for business process reengineering costs, as discussed in Note 1 to
the financial statements.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of SPX Corporation and
subsidiaries as of December 31, 1998 and the results of their operations and
their cash flow for the year then ended, in conformity with generally accepted
accounting principles.

ended December 31, 1997. These financial statements are the responsibility of
the company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

operations and their cash flows for each of the two years in the period ended
December 31, 1997, in conformity with generally accepted accounting principles.
 
     As discussed in the notes to the financial statements, in 1997 the company
changed its method of accounting for business process reengineering costs.

                        SPX CORPORATION AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               DECEMBER 31, 1998
        (DOLLAR AND SHARE AMOUNTS IN MILLIONS, EXCEPT PER SHARE AMOUNTS)
 
(1) SUMMARY OF ACCOUNTING POLICIES
 
     The significant accounting and financial policies of SPX Corporation ("SPX"
or the "company") are described below.
 
     Basis of Presentation -- The preparation of the company's consolidated
     financial statements in conformity with generally accepted accounting
     principles requires management to make estimates and assumptions. These
     estimates and assumptions affect the reported amounts of assets and
     liabilities, the disclosure of contingent assets and liabilities at the
     date of the consolidated financial statements, and the reported amounts of
     revenues and expenses during the reporting period. Actual results could
     differ from those estimates.
 
     Consolidation -- The consolidated financial statements include the accounts
     of the company and its majority owned subsidiaries after elimination of
     intercompany accounts and transactions. Investments in unconsolidated
     companies where the company exercises significant influence are accounted
     for using the equity method.
 
     Cash Equivalents -- The company considers its highly liquid money market
     investments with original maturities of three months or less to be cash
     equivalents.
 
     Revenue Recognition -- The company generally recognizes revenues from
     product sales upon shipment to the customer. Revenue from service contracts
     and long-term maintenance arrangements is deferred and recognized on a pro
     rata basis over the agreement period. Revenues on certain long-term
     contracts are recognized using the percentage-of-completion method of
     accounting. Under this method, earnings accrue, generally based on the
     percentage of total costs incurred or total units of products delivered, as
     contracts progress toward completion.
 
     Research and Development Costs -- Research and development costs are
     expensed as incurred and were $73.4 in 1998, $45.7 in 1997 and $47.5 in
     1996.
 
     Environmental Remediation Costs -- Costs incurred to investigate and
     remediate environmental issues are expensed unless costs incurred extend
     the economic useful life of related assets employed by the company.
     Liabilities are recorded and expenses are reported when it is probable that
     an obligation has been incurred and the amounts can be reasonably
     estimated. The company's environmental accruals cover anticipated costs,
     including investigation, remediation, and operation and maintenance of
     clean-up sites. Environmental obligations are not discounted and are not
     reduced by anticipated insurance recoveries.
 
     Property, Plant and Equipment -- Property, plant and equipment ("PP&E") are
     stated at cost, less accumulated depreciation and amortization. The company
     uses the straight-line method for computing depreciation expense over the
     useful lives of PP&E, which do not exceed 40 years for buildings and range
     from 3 to 15 years for machinery and equipment. Leasehold improvements are
     amortized over the life of the related asset or the life of the lease,
     whichever is shorter.
 
     Financial Instruments -- The company does not enter into financial
     instruments for speculative or trading purposes. The company records the
     net amount to be paid or received under interest rate protection agreements
     over the life of the agreement as a component of interest expense. Gains
     and losses related to forward foreign exchange and option contracts that
     qualify for hedge accounting treatment are deferred and offset against
     losses and gains when the underlying transaction occurs. Gains or losses at
     the time of maturity, termination, sale or repayment of a financial
     instrument contract designated as a hedge are included in earnings. Gains
     and losses related to qualifying hedges of firm commitments or anticipated

     transactions are deferred and are recognized in income or as adjustments of
     carrying amounts when the hedged transaction occurs.
 
     Goodwill and Intangible Assets -- The company amortizes its goodwill and
     intangible assets on a straight-line basis over lives ranging from 10 to 40
     years. In determining the estimated useful lives, management considers the
     nature, competitive position, life cycle position, and historical and
     expected future operating income of each acquired company, as well as the
     company's commitment to support these acquired companies through continued
     investment in capital expenditures, operational improvements, and research
     and development. After an acquisition, the company continually reviews
     whether subsequent events and circumstances have occurred that indicate the
     remaining estimated useful lives of goodwill and intangible assets may
     warrant revision or that the remaining balance of goodwill and intangible
     assets may not be recoverable. If events and circumstances indicate that
     goodwill and intangible assets related to a particular business should be
     reviewed for possible impairment, the company uses projections to assess
     whether future operating income on a non-discounted basis (before
     amortization) of the unit is likely to exceed the amortization over the
     remaining lives of the goodwill and intangible assets, to determine whether
     a write down of goodwill and intangible assets to recoverable value is
     appropriate.
 
     Accounting Pronouncements -- In the fourth quarter of 1997, the company
     recorded a $3.7 charge, net of tax of $1.4, to write-off previously
     capitalized business process engineering costs in accordance with a new
     accounting principle which required all previously capitalized business
     process reengineering costs to be expensed as a cumulative effect of a
     change in accounting principle.
 
     Statement of Position 98-1 "Accounting for Computer Software Developed for
     or Obtained for Internal Use" ("SOP 98-1") provides guidance for accounting
     for software developed for internal use. The company is required to adopt
     SOP 98-1 in 1999 and management believes that such adoption will not have a
     material effect on the company's results of operations and financial
     position.
 
     Statement of Financial Accounting Standards ("SFAS") No. 133 "Accounting
     for Derivative Instruments and Hedging Activities," which will become
     effective January 2000, establishes accounting and reporting standards for
     derivative instruments and hedging contracts. It also requires all
     derivatives to be recognized as either assets or liabilities in the balance
     sheet at fair value and changes in fair value to be recognized in income.
     Management is currently analyzing the impact of this statement, but does
     not anticipate that the effect on the company's results of operations and
     financial position will be material.
 
     Reclassifications -- Certain reclassifications were made to conform prior
     years' data to the current presentation. Unless otherwise noted, historical
     share and earnings per share disclosures have been adjusted to reflect the
     0.4186 share of SPX common stock ("Exchange Ratio") that General Signal
     Corporation ("GSX") shareholders received for each share of GSX common
     stock upon the merger of SPX and GSX (see Note 2).
 
(2) MERGER OF SPX AND GSX
 
     On October 6, 1998 (the "Merger Date"), GSX merged into a subsidiary of SPX
Corporation (the "Merger"). On an aggregate basis, GSX shareholders received
0.4186 share of SPX common stock and $18.00 in cash for each share owned of GSX
common stock. In total, approximately 18.236 million shares of SPX common stock
and $784.2 in cash were exchanged for the outstanding common stock of GSX.
Outstanding restricted stock and stock options of GSX were either redeemed
through change of control payments or terminated.

        (DOLLAR AND SHARE AMOUNTS IN MILLIONS, EXCEPT PER SHARE AMOUNTS)
 
     The Merger was accounted for as a reverse acquisition whereby GSX was
treated as the acquirer and SPX as the acquiree, because GSX shareholders owned
a majority of the company as of the Merger Date and GSX was approximately twice
the size of SPX. Purchase accounting was performed on SPX based upon its fair
market value at the transaction date. The cash portion of the consideration was
accounted for as a dividend by the company.
 
     The fair market value of SPX was based on the average per share value of
SPX's common stock near July 17, 1998-the date that the Merger agreement was
signed. Additionally, since the company assumed the stock options outstanding of
SPX, the fair value of these options was included in determining the valuation
of SPX.
 
     The valuation of SPX, including transaction fees of $15.6, was $776.6. A
summary of assets and liabilities acquired, at estimated fair market value was
as follows:

     The intangibles, including customer lists of $118.0, developed technologies
of $85.8, trademarks and work force of $73.0, and goodwill will be amortized
over 10 to 40 years. The valuation included in-process technology of $9.0, which
was expensed in the fourth quarter of 1998. The valuations of identifiable
intangibles and in-process technology were based upon independent external
appraisals.
 
     The company obtained a new $1,650.0 financing facility, including a $250.0
Revolving Loan. Three term loans aggregating $1,400.0 funded various payments
due upon the Merger, including the cash consideration and the refinancing of
certain debt (see Note 14).
 
     The accompanying consolidated financial statements include the results of
GSX for all periods and the results of SPX beginning on the Merger Date. The
following unaudited 1998 and 1997 pro forma selected financial data reflect the
Merger and related financing as if they had occurred as the beginning of the
applicable year. The 1997 pro forma financial data also reflect SPX's 1997
disposition of its *Sealed Power division, GSX's 1997 disposition of its General
Signal Pump Group ("GSPG"), and GSX's 1997 contribution of its General Signal
Electric Group ("GSEG") to EGS Electrical Group LLC ("EGS"), a venture with
Emerson Electric Co., as if such transactions had occurred on January 1, 1997.
The unaudited pro forma financial data does not purport to represent what the
company's results from continuing operations would actually have been had the
transactions in fact occurred as of an earlier date, or project the results for
any future date or period.

     No individual foreign country in which the company operates accounted for
more than 5% of consolidated revenues in 1998, 1997 or 1996.
 
(4) SPECIAL CHARGES
 
     After the Merger, the company recorded special charges of $101.7, which
included $69.3 of costs associated with closing the former GSX corporate office
and $32.4 of restructuring costs related to GSX operations. The components of
the charge have been computed based on actual cash payouts, management's
estimate of the realizable value of the affected tangible and intangible assets
and estimated exit costs including severance and other employee benefits based
on existing severance policies and local laws.
 
CLOSING OF GSX CORPORATE HEADQUARTERS
 
     These charges include $65.3 of cash costs related to change of control
agreements, option and restricted stock payments, and other employee termination
costs for 88 corporate GSX employees. Substantially all

scheduled terminations and payments were complete by December 31, 1998.
Additionally, a $4.0 charge was recorded for the GSX corporate headquarters
building, which was closed in late 1998. The charge principally represents
rental costs until the lease termination in early 2000 ($2.4) and
non-transferable property write downs ($1.6).
 
RESTRUCTURING CHARGE
 
     The company offered an early retirement program to employees at most of the
GSX operations. Approximately 325 hourly and salaried employees accepted the
offer during the fourth quarter, at a cost of $14.2, which represents
incremental salary to be paid in return for accepting early retirement.
Substantially all such employees will retire by March 31, 1999. Additionally,
during the fourth quarter of 1998, the company committed to close 18
manufacturing, sales and administrative facilities primarily to consolidate
various GSX operations. As a result of these actions, the company recorded
charges of $10.1 for severance payments to approximately 800 other employees
(approximately 330 of which were terminated by December 31, 1998 with the
remaining expected to be terminated by mid-1999) and $8.1 for facility closing
costs (including holding costs of $2.5 and non-cash property write downs of
$4.6). The restructuring of these operations was in response to new management's
assessment of those operations and an effort to minimize inefficiencies and
duplicative functions.
 
     The facility closings should be substantially complete by the end of the
first quarter of 1999. The company expects that approximately $10.0 of
incremental costs associated with these actions will be incurred in the first
and second quarters of 1999. These costs relate to moving and relocation
expenses, incentives to employees to finish production and other activities, and
other miscellaneous costs that did not qualify for accrual in 1998. Generally,
functions performed at the affected facilities will be consolidated into
continuing facilities. The company will also exit manufacturing activities
related to certain unprofitable product lines. Revenues and operating results
related to these exited product lines were not material.
 
(5) DISCONTINUED OPERATIONS AND BUSINESS DIVESTITURES
 
     In 1997, the company reversed $3.8 ($2.3 after-tax) of accruals related to
discontinued operations which the company determined were no longer required.
These accruals were originally recorded in 1995. Substantially all related
assets of these operations were sold by the end of 1996.
 
     In August 1997, the company sold substantially all of the assets of GSPG to
Pentair, Inc. for approximately $200.0 and recognized a pretax gain of $63.7
($17.2 after-tax). The effective tax rate differs from the U.S. statutory tax
rate due to a difference in the book and tax basis of GSPG. Annual 1996 revenues
of GSPG were approximately $201.0.
 
     In the fourth quarter of 1997, the company sold its equity interest in a
company in Mexico for a pretax gain of $9.0($2.3 after-tax). The effective tax
rate on the Mexico gain differs from the U.S. statutory tax rate due to a
difference in the book and tax basis of the equity investment sold.
 
     In 1996, the company sold Kinney Vacuum Company for $29.0 and recognized a
pretax gain of $20.8($12.5 after-tax). Annual 1995 revenues were approximately
$25.0.

(7) EMPLOYEE BENEFIT PLANS
 
BENEFIT PENSION AND POSTRETIREMENT PLANS
 
     The company has defined benefit pension plans that cover substantially all
salaried and hourly paid employees, including certain employees in foreign
countries. These plans provided pension benefits that were based on the
employees' years of credited service and levels of earnings. Effective January
1, 1999, the company amended its plan formula to provide benefits using a cash
balance program. Under the new cash balance program, participants receive
benefits based on a percentage of current salary and interest credits. The
company funds United States ("U.S.") pension plans in amounts equal to the
minimum funding requirements of the Employee Retirement Income Security Act of
1974, plus additional amounts that may be approved from time to time.
Substantially all plan assets are invested in cash and short-term investments or
listed stocks and bonds and real estate. Plan assets include 0.470 shares of the
company's common stock. Plan assets and obligations of non-North American
subsidiaries are not material and are not included below.
 
     The company has domestic postretirement plans that provide health and life
insurance benefits for retirees. Some of these plans require employee
contributions at varying rates. Not all employees are eligible to receive these
benefits, with eligibility governed by the plan(s) in effect at a particular
location. Certain of the company's non-North American subsidiaries have similar
plans for retirees. The company's obligations for such plans are not material
and are not included below.

     A minimum pension liability adjustment is required when the actuarial
present value of accumulated benefits exceeds plan assets and accrued pension
liabilities. The minimum liability adjustment, less allowable intangible assets,
net of tax benefit, is reported as other comprehensive income and accumulated to
$2.4 and $1.7 as of December 31, 1998 and 1997, respectively.
 
     As part of the early retirement program offered and the work force
reduction committed to in the fourth quarter of 1998 (see Note 4), the company
recorded special termination benefits of $14.2, which is included in the fourth

     During 1997, the company's accrued postretirement benefit cost was reduced
by curtailment gains and settlement gains of approximately $7.9 related to the
disposition of GSPG and the formation of EGS. The curtailment gain recognized on
the disposition of GSPG is included in the gain on the sale (see Note 5). The

     The accumulated postretirement benefit obligation was determined using the
terms of the company's various plans, together with relevant actuarial
assumptions and health care cost trend rates. The estimated annual rates ranged

RETIREMENT SAVINGS AND EMPLOYEE STOCK OWNERSHIP PLAN
 
     Concurrent with the Merger, the company assumed the SPX KSOP plan ("Plan"),
which provides benefits to a majority of domestic employees. These employees can
contribute up to 15% of their earnings to the Plan, subject to certain
limitations. The company matches a portion of the employee's contribution with

shares from the Plan's trust. During the fourth quarter of 1998, 0.015 shares
were allocated to employees under the Plan. Compensation expense is recorded
based upon the market value of shares as the shares are allocated to employees.
In 1998, $0.8 was recorded as compensation expense. Employees may vote their
allocated shares directly, while the KSOP trustee votes the unallocated shares
in the trust proportionally on the same basis as the allocated shares voted. At
December 31, 1998, there were 0.516 unallocated shares in the trust with a fair
market value of $34.6. Beginning January 1, 1999, the GSX Savings and Stock
Ownership Plan ("GSX Plan") was merged with the Plan.
 
     The company matched employee contributions, to the GSX Plan and other
supplemental plans, in cash and common stock equal to a percentage of certain
amounts contributed by employees. The company's contributions under these plans
amounted to $23.7 in 1998, $13.2 in 1997 and $10.6 in 1996.

     Inventories include material, labor and factory overhead costs, and are
reduced, when necessary, to estimated realizable values. Certain domestic
inventories are valued using the last-in, first-out ("LIFO") method. Such
inventories were $127.1 and $48.6 at December 31, 1998 and 1997, respectively.
All other inventories are valued using the first-in, first-out ("FIFO") method.
In 1997, a LIFO liquidation of $2.0 was included in the gain of GSPG.
Additionally, $5.3 of the excess of FIFO cost over LIFO inventory value was
transferred from GSEG to the investment in EGS. Progress payments, netted
against work in process at year-end, were $15.2 in 1998 and $10.1 in 1997.
 
(9) CONTRACTS IN PROGRESS
 
     Prepaid expenses and other current assets include contracts in progress of
$3.1 and $3.4 at December 31, 1998 and 1997, respectively. Contracts in progress
represent revenue recognized on a percentage-of-completion basis over related
progress billings of $2.3 and $60.5 at December 31, 1998 and 1997, respectively.
Substantially all contracts in progress at year-end are billed during the
subsequent year.
 
(10) INVESTMENT IN EGS
 
     In the third quarter of 1997, the company and Emerson Electric Co. formed
EGS, a venture combining Emerson's Appleton Electric operations and the
company's GSEG. The company contributed substantially all of the operating
assets of GSEG in exchange for a 47.5% ownership in EGS. Annual 1996 revenues
for GSEG were approximately $294.0. In October 1998, the company's ownership in
EGS was reduced to 44.5% when the company received two businesses of EGS in a
partial rescission of the original formation of EGS. Annual 1998 sales of these
two businesses were approximately $75.0. The company recorded the original
contribution and partial rescission at historical cost.

     The company accounts for its investment in EGS under the equity method of
accounting. Effective January 1, 1998, the company began accounting for its
investment in EGS on a three-month lag basis and, net of the effect of the
returned businesses, recorded a $9.6 adjustment through retained earnings to
reverse the fourth quarter 1997 equity earnings from this venture. EGS operates
primarily in the United States, Canada and Mexico. EGS's results of operations
for its fiscal year ended September 30, 1998 were as follows:

     EGS' pre-tax income for the quarter ended December 31, 1998 was not
materially different than the pre-tax income earned the previous quarter.
 
     The company's equity in earnings of EGS was $40.2 and $11.8 for the years
ended December 31, 1998 and 1997, respectively. The company's recorded
investment in EGS was approximately $122.00 and $65.0 less than its ownership of
EGS's net assets at December 31, 1998 and 1997, respectively. This difference is
being amortized on a straight-line basis over an estimated economic life of 40
years.

     Realization of deferred tax assets associated with the net operating loss
("NOL") and credit carryforwards is dependent upon generating sufficient taxable
income prior to their expiration. Management believes that there is a risk that
certain of these NOL and credit carryforwards may expire unused and,
accordingly,

has established a valuation allowance against them. Although realization is not
assured for the remaining deferred tax assets, management believes it is more
likely than not that the deferred tax assets will be realized through future
taxable earnings or alternative tax strategies. However, deferred tax assets
could be reduced in the near term if management's estimates of taxable income
during the carryforward period are significantly reduced or alternative tax
strategies are no longer viable. The valuation allowance decreased in 1998 and
1997 by $5.3 and $13.3, respectively.
 
     Undistributed earnings of the company's foreign subsidiaries amounted to
approximately $86.6 at December 31, 1998. Those earnings are considered to be
indefinitely reinvested and, accordingly, no provision for U.S. federal and
state income taxes or foreign withholding taxes has been made. If these earnings
were distributed, the company would be subject to U.S. income taxes (subject to
a reduction for foreign tax credits) and withholding taxes payable to the
various foreign countries. Determination of the amount of unrecognized deferred
U.S. income tax liability is not practicable; however, unrecognized foreign tax
credit carryovers would be available to reduce some portion of the U.S.
liability. Withholding taxes of approximately $7.8 would be payable upon
remittance of all previously unremitted earnings at December 31, 1998.

     Aggregate maturities of total debt are $49.1 in 1999, $298.3 in 2000,
$112.8 in 2001, $164.8 in 2002, $156.5 in 2003 and $734.1 thereafter.
 
     In connection with the Merger, the company obtained a $1,650.0 credit
facility consisting of a six year, $600.0 Tranche A Loan ("Tranche A Loan"), an
eight year, $600.0 Tranche B Loan ("Tranche B Loan"), an eighteen month, $200.0
Interim Term Loan ("Interim Loan") and a six year, $250.0 Revolving Facility
("Revolving Loan") collectively hereinafter referred to as the "New Credit
Facility." On October 6, 1998, $1,400.0 was drawn on the New Credit Facility and
was used to finance the cash portion of the Merger and to repay certain
indebtedness of SPX and GSX and pay certain transaction costs (see Note 2).
 
     The New Credit Facility bears interest at variable rates using a calculated
base borrowing rate ("Base Rate") or a Eurodollar Rate, plus the applicable
margin. The applicable margin for the Tranche B Loan is 2.5% for Base Rate
borrowings and 3.5% for Eurodollar Rate borrowings. The Tranche A Loan, Interim
Loan and Revolving Loan have variable margins between 0.5% and 1.75% for Base
Rate loans and 1.5% and 2.75% for Eurodollar Rate borrowings. The Revolving Loan
also is subject to annual commitment fees of 0.25% to 0.5% on the unused portion
of the facility. The variable margins and commitment fees are based on certain
financial measurements of the company as defined in the New Credit Facility.

quarterly. The company has effectively fixed the underlying Eurodollar rate at
approximately 4.8% on $800.0 of indebtedness through interest rate protection
agreements over the next three years. At December 31, 1998, the weighted average
interest rate on outstanding debt under the New Credit Facility was 8.2%,
reflecting the 4.8% fixed Eurodollar rate on $800.0.
 
     The New Credit Facility is secured by substantially all of the assets of
the company (excluding EGS) and requires the company to maintain certain
leverage and interest coverage ratios. The New Credit Facility also requires
compliance with certain operating covenants which limit, among other things, the
incurrence of additional indebtedness by the company and its subsidiaries, sales
of assets, the distribution of dividends, capital expenditures, mergers,
acquisitions and dissolutions. Under the most restrictive of the financial
covenants, the company will be required to maintain (as defined) a maximum debt
to earnings before income taxes, depreciation and amortization ratio and a
minimum interest coverage ratio beginning in March 1999 and becoming more
restrictive thereafter.
 
     The agreement also provides a letter of credit facility, which is available
for the issuance of standby letters of credit in an aggregate amount of $150.0.
Standby letters of credit issued under this facility, $56.3 at December 31,
1998, reduce the aggregate amount available under the Revolving Loan commitment.
 
     The company also has a $20.0 swingline loan facility ("Swingline") to
assist in managing daily cash requirements, none of which was outstanding at
December 31, 1998. Loans under the Swingline bear interest at the Base Rate plus
1.75% at December 31, 1998.
 
(15) FINANCIAL INSTRUMENTS
 
FINANCIAL DERIVATIVES
 
     The company conducts its business in various foreign currencies.
Accordingly, the company is subject to the typical currency risks and exposures
that arise as a result of changes in the relative value of currencies. The risks
are often referred to as transactional, commitment, translational and economic
currency exposures. The company's risk management policy (the "Policy") stresses
risk reduction and specifically prohibits speculation. The Policy's three basic
objectives are to reduce currency risk on a consolidated basis, to protect the
functional currency value of foreign currency-denominated cash flows and to
reduce the volatility that changes in foreign exchange rates may present to
operating income.
 
     The company utilizes natural hedges and offsets to reduce exposures and
also combines positions to reduce the cost of hedging. The company entered into
forward foreign exchange contracts to hedge net consolidated currency
transaction exposure for periods consistent with the terms of the underlying
transactions, extending through 1999. At December 31, 1998, the company had a
notional amount of approximately $23.0 of such contracts outstanding.
 
     From time to time the company enters into various interest rate protection
agreements to reduce the potential impact of increases in interest rates on
floating rate long-term debt. At December 31, 1998, the company was a party to
four interest rate swap agreements ("Swaps"), covering $800.0 of outstanding
debt obligations and expiring in 2001, and three interest rate caps ("Caps"),
covering an additional $200.0 of outstanding debt obligations and expiring in
1999. The Swaps entitle the company to receive from or require the company to
pay to counterparties, on a quarterly basis, the amounts, if any, by which LIBOR
varies from approximately 4.8%. The Caps place a LIBOR rate ceiling of 6.5% on
the obligations covered.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The carrying amount of cash and equivalents and receivables reported on the
consolidated balance sheets approximates their fair value because of the short
maturity of those instruments.

        (DOLLAR AND SHARE AMOUNTS IN MILLIONS, EXCEPT PER SHARE AMOUNTS)
 
     The fair value of the company's debt instruments, based on borrowing rates
available to the company at each yearend for similar debt, is not materially
different than its carrying value.
 
     As collateral for performance on contracts and as credit guarantees to
banks and insurers, the company is contingently liable under standby letters of
credit in the amount of $56.3 and $104.3 at December 31, 1998 and 1997,
respectively. The company pays fees to various banks for these letters of credit
that were 2.95% per annum of their face value at December 31, 1998. If the
company was required to obtain replacement standby letters of credit as of
December 31, 1998 for those currently outstanding, it is the company's opinion
that the replacement costs would not significantly vary from the present fee
structure.
 
     At December 31, 1998, the company had a $7.3 unrealized gain related to the
Swaps and the market value of the company's Caps was not material.
 
CONCENTRATIONS OF CREDIT RISK
 
     Financial instruments that potentially subject the company to significant
concentrations of credit risk consist of cash and temporary investments, trade
accounts receivable and interest rate protection agreements.
 
     Cash and temporary investments are placed with various high quality
financial institutions throughout the world and exposure is limited at any one
institution. The company periodically evaluates the credit standing of these
financial institutions.
 
     Concentrations of credit risk arising from trade accounts receivable are
due to the company selling to a large number of customers in the industrial and
motor vehicle industries, particularly in the United States. The company
performs ongoing credit evaluations of its customers' financial conditions and
does obtain collateral or other security when appropriate. No one customer
accounts for more than 10% of the company's revenues.
 
     The company is exposed to credit losses in the event of nonperformance by
counterparties to its interest rate protection agreements, but has no other
off-balance-sheet credit risk of accounting loss. The company anticipates,
however, that counterparties will be able to fully satisfy their obligations
under the contracts. The company does not obtain collateral or other security to
support financial instruments subject to credit risk but monitors the credit
standing of counterparties.

GENERAL
 
     On April 11, 1996, the company was named as a defendant in an action filed
in Federal Court for the Northern District of Illinois. Snap-on Incorporated,
Snap-on Tools Company and Snap-on Technologies, Inc. v. Ronald J. Ortiz and SPX
Corporation, No. 96C2138, U.S. District Court for the Northern District of
Illinois. The Complaint contained seventeen counts, fifteen of which were
directed to the company. Of the fifteen counts directed to the company, seven
were related to the hiring in 1992 of a former officer of Sun Electric
Corporation, five contained allegations of patent infringement and three sought
a declaration of invalidity of patents held by the company. On June 28, 1996,
the company filed an eight count counterclaim, containing three counts of patent
infringement and five counts for declaration of invalidity of patents held by
the Plaintiffs. These patents pertain to certain features related to performance
test equipment manufactured by Sun, Snap-on and the company. At that time, the
company also filed a motion to dismiss five of the counts of the Complaint
related to the hiring of the former Sun executive. On October 23, 1996, four of
those counts of the Complaint were dismissed, three with prejudice and one with
leave to amend. Since that time, a further motion to dismiss one of those counts
was filed and granted. Document discovery has proceeded and depositions have
been conducted. In 1995 and 1997, the Plaintiffs initiated reexamination of the
three company patents. The U.S. patent office has upheld the validity of the
three company patents by issuing reexamination certificates on one of the
patents in late 1998 and on the other two in early 1999. Neither the Complaint
nor the counterclaim contain specific allegations of damages, however, the
products affected by the patents at issue are significant for Sun, Snap-on and
the company. Management expects that the claims against the company are without
merit. Based on management's understanding of Sun and Snap-on products sold
during the alleged infringement period, management believes that a reasonable
value of the company's claims brought against Sun and Snap-on could be material
to the future results of operations, cash flows and financial position of the
company. Management intends to vigorously prosecute its claims. The company
believes it should ultimately prevail on this litigation. However, since the
amount of the damages cannot be fully quantified until the legal discovery
process proceeds further and no assurances can be made as to the final timing
and outcome of any litigation, no gain has been recorded. Refer to "Factors That
May Affect Future Results" and " Safe Harbor for Forward Looking Statements" in
Management's Discussion and Analysis of Financial Condition and Results of
Operations.
 
     Certain claims, including environmental matters, suits and complaints
arising in the ordinary course of business, have been filed or are pending
against the company and certain of its subsidiaries. In the opinion of
management, such matters are without merit or are of such kind, or involve such
amounts, as would not have a significant effect on the financial position,
results of operations, or cash flows of the company if disposed of unfavorably.
 
ENVIRONMENTAL MATTERS
 
     The company's operations and properties are subject to federal, state,
local, and foreign regulatory requirements relating to environmental protection.
It is the company's policy to comply fully with all such applicable
requirements. As part of its effort to comply, the company has a comprehensive
environmental compliance program which includes environmental audits conducted
by internal and external independent professionals and regular communications
with the company's operating units regarding environmental compliance
requirements and anticipated regulations. Based on current information,
management believes that the company's operations are in substantial compliance
with applicable environmental laws and regulations, and the company is not aware
of any violation that could have a material adverse effect on the business,
financial conditions, results of operations, or cash flows of the company. The
company is engaged in site investigation and/or remediation at 33 company owned
or controlled sites and estimates, based upon currently available information,
that its aggregate probable remaining liability at these sites is approximately
$61.5. There can be no assurance, however, that currently unknown matters, new
laws and regulations,

        (DOLLAR AND SHARE AMOUNTS IN MILLIONS, EXCEPT PER SHARE AMOUNTS)
 
or stricter interpretations of existing laws and regulations will not materially
affect the company's business or operations in the future.
 
     In the case of contamination at offsite, non-owned facilities, the company
has been notified that it is a potentially responsible party and has received
other notices of potential liability pursuant to various environmental laws at
22 sites. Such laws may impose liability on certain persons that are considered
jointly and severally liable for the costs of investigation and remediation of
hazardous substances present at these sites, regardless of fault or legality of
the original disposal. The persons include the present or former owner or
operator of the site and companies that generated, disposed of, or arranged for
the disposal of, hazardous substances at the site. The company is considered a
"deminimis" potentially responsible party at most of the sites and estimates the
aggregate probable remaining liability at these sites is approximately $3.5.
 
     The potential costs related to these environmental matters and the possible
impact on future operations are uncertain due in part to the complexity of
government laws and regulations and their interpretations, the varying costs and
effectiveness of clean-up technologies, the uncertain level of insurance or
other types of recovery, and the questionable level of the company's
responsibility. The company has estimated that costs of investigation and
remediation for these matters will be approximately $65.0 overall and has
included this amount in accrued liabilities in the accompanying balance sheet.
It is at least reasonably possible, however, that a change in this estimate will
occur. In management's opinion, after considering reserves established for such
purposes, remedial actions for compliance with the present laws and regulations
governing the protection of the environment are not expected to have a material
adverse impact on the company's business, financial condition, results of
operations, or cash flows.
 
EXECUTIVE SEVERANCE AGREEMENTS
 
     The company's Board of Directors has adopted executive severance
agreements, which create certain liabilities in the event of the termination of
the covered executives following a change of control of the company. The
aggregate commitment under these executive severance agreements should all six
covered employees be terminated is approximately $19.7. Additionally, should a
change in control occur, restrictions on any outstanding restricted stock, any
outstanding stock options, unvested pension entitlements and the EVA Incentive
Compensation Plan bonus bank would lapse.

SPX STOCK COMPENSATION PLANS
 
     At the time of the Merger, the company adopted SPX's pre-existing stock
compensation plans.
 
     Under the 1992 Stock Compensation Plan, as amended in October 1998, up to
3.0 shares of the company's common stock may be granted to key employees and 1.1
such shares are available for grant at December 31, 1998. Awards of stock
options, stock appreciation rights ("SAR"), performance units and restricted
stock may be made under the Plan although no more than 0.2 shares may be granted
in the form of restricted stock.
 
     Stock options may be granted to key employees in the form of incentive
stock options or nonqualified stock options, vest 50% after two years and 100%
after three years, and expire no later than 10 years from the date of grant. The
option price per share may be no less than the fair market value of the common
stock of the company on the date of grant. Upon exercise, the employee has the
option to surrender shares at current value

in payment of the exercise price and/or for withholding tax obligations, and,
subject to certain restrictions, may receive a reload option having an exercise
price equal to the current market value for the number of shares so surrendered.
The reload option expires at the same time that the exercised option would have
expired.
 
     No SARs or performance units have been granted under this plan.
 
     Restricted stock may be granted to key individuals to recognize or foster
extraordinary performance, promotion, recruitment or retention. At the time of
the grant, restrictions are placed on ownership of the shares for a stated
period of time during which a participant will not be able to dispose of the
restricted shares. Upon lapse of the restriction period, complete ownership is
vested in the participant and the shares become freely transferable.
 
     Under the 1997 Non-employee Directors Compensation Plan, up to 0.075 shares
of common stock have been reserved for issuance (of which 0.048 shares remain as
of December 31, 1998).
 
GSX STOCK INCENTIVE PROGRAM
 
     Prior to the Merger, GSX had a stock incentive program whereby executive
officers and designated employees were granted restricted stock and options to
purchase shares of company common stock. The only compensation expense recorded
under this program was related to restricted stock awards and aggregated $1.0 in
both 1998 and 1997.
 
     The following table shows the GSX option and restricted stock activity from
the period December 31, 1995 through the Merger Date and has not been restated

     The company has adopted the disclosure-only provisions of Statement of
Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" ("SFAS No. 123"). Accordingly, no compensation cost has been

stock options been determined based on the fair value at the grant date for
awards in 1998, 1997 and 1996 consistent with the accounting provisions of SFAS
No. 123, the company's net income (loss) and income (loss) per share would have

     The application of SFAS No. 123 resulted in a lower pro forma net loss in
1998, because some of the expense recorded when the GSX options were repurchased
upon the Merger had, on a pro forma basis, been recognized prior to 1998.
 
     The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option-pricing model with the following weighted-average
assumptions:

</TABLE>
 
     The weighted-average fair value of options granted during 1997 and 1996 was
$10.85 and $9.08, respectively, and $17.46 for options granted during the fourth
quarter of 1998.
 
SHAREHOLDER RIGHTS PLAN
 
     Subsequent to the Merger, and pursuant to a pre-existing Shareholder Rights
Agreement, each share of common stock carries one preferred stock purchase
right. Each right entitles the holder, upon the occurrence of certain events, to
purchase one one-thousandth of a share of a new series of junior participating
preferred stock for $200 per share. Furthermore, if the company is involved in a
merger or other business combination at any time after the rights become
exercisable, the rights will entitle the holder to buy the number of shares of
common stock of the acquiring company having a market value of twice the then
current exercise price of each right. Alternatively, if a 20% or more
shareholder acquires the company by means of a reverse merger in which the
company and its stock survive, or engages in self-dealing transactions with the
company, or if any person acquires 20% or more of the company's common stock,
then each right not owned by a 20% or more shareholder will become exercisable
for the number of shares of common stock of the company having a market value of
twice the then current exercise price of each right. The rights, which do not
have voting rights, expire on June 25, 2006, and may be redeemed by the company
at a price of $.01 per right at any time prior to

(1) On December 12, 1996, the company called for the redemption of its $100.0
    5.75% convertible subordinated notes. As of December 31, 1996, notes with a
    face value of $57.4 had been converted into 1.5 shares of GSX common stock
    (before adjustment for the Merger), with an additional $39.6 converted into
    1.0 shares of GSX's common stock (before adjustment for the Merger), on
    January 2, 1997. The balance of the notes were redeemed for cash in early
    1997.
 
(2) In computing weighted average shares outstanding for diluted earnings per
    share for the year ended December 31, 1998, common stock equivalents
    resulting from stock options outstanding of 0.2 shares were not included as
    they would have been anti-dilutive to the earnings per share calculation.

the Company's management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of EGS
Electrical Group, LLC and subsidiaries as of September 30, 1998, and the results

                               SEPTEMBER 30, 1998
                             (DOLLARS IN THOUSANDS)
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
DESCRIPTION OF BUSINESS
 
     EGS Electrical Group, LLC (EGS) was created on September 15, 1997 by
combining the electrical groups of Emerson Electric Co. (Emerson) and General
Signal, Inc. (General Signal). Emerson holds 52.5% of equity and General Signal
holds 47.5%. General Signal subsequently merged with SPX Corporation (SPX), with
SPX becoming the minority member.
 
     EGS and subsidiaries (the Company) operates offices, plants, and warehouses
in fifteen states and five foreign countries and is engaged in the manufacture
of electrical fittings, enclosures, controls and industrial lighting;
transformers, power conditioning, power protection and power supplies; emergency
and exit lighting, ILS systems; signaling devices; resistance wire electrical
heating cable, and pipe tracing cable; and a variety of electrical heating
products. Approximately 15% of the Company's assets are located outside the
United States, primarily in Canada and France.
 
PRINCIPLES OF CONSOLIDATION
 
     The consolidated financial statements include the accounts of EGS and its
controlled affiliates. All significant intercompany transactions, profits, and
balances are eliminated in consolidation.
 
FOREIGN CURRENCY TRANSLATION
 
     The functional currency of the Company's non-U.S. subsidiaries is the local
currency. Adjustments resulting from the translation of financial statements are
reflected as a separate component of members' equity.
 
CASH EQUIVALENTS
 
     Cash equivalents consist of highly liquid investments with original
maturities of three months or less.
 
INVENTORIES
 
     Inventories are valued at the lower of cost or market. Cost is determined
using the "first in, first out" method for all inventories.
 
PROPERTY, PLANT, AND EQUIPMENT
 
     The Company records investments in land, buildings, and machinery and
equipment at cost. Depreciation on plant and equipment is calculated on the
straight-line method over the estimated useful lives of the assets. Useful lives
are 12 years for machinery and equipment, and 40 years for buildings and
improvements.
 
EXCESS OF COST OVER NET ASSETS OF PURCHASED BUSINESSES
 
     Assets and liabilities related to business combinations accounted for as
purchase transactions are recorded at their respective fair value. The excess of
cost over net assets of purchased businesses is amortized on a straight-line
basis over the expected periods of benefit, not exceeding 40 years. Long-lived
assets are reviewed for impairment whenever events and changes in business
circumstances indicate the carrying value of the assets may not be recoverable.
Impairment losses are recognized if expected future undiscounted cash flows of
the related assets are less than their carrying values.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
                               SEPTEMBER 30, 1998
                             (DOLLARS IN THOUSANDS)
 
INCOME TAXES
 
     The Company does not pay United States federal income taxes. Federal taxes
are paid at the member level. The Company does pay some state income taxes in
those states that do not follow the federal treatment of Limited Liability
Corporations (LLC) and foreign taxes are paid on income attributable to the
foreign entity. Income taxes paid during the year ended September 30, 1998 were
$801.
 
REVENUE RECOGNITION
 
     The Company recognizes nearly all of its revenues through the sale of
manufactured products as shipped.
 
USE OF ESTIMATES
 
     Management of the Company has made a number of estimates and assumptions
relating to the reporting of assets and liabilities and the disclosure of
contingent assets and liabilities to prepare these financial statements in
conformity with generally accepted accounting principles. Actual results could
differ from those estimates.
 
(2) ACQUISITIONS
 
     On June 1, 1998, the Company acquired Easy Heat, Inc., a company that
designs and manufactures freeze protection and electrical heating products,
(Easy Heat) for approximately $23,800 in cash. Easy Heat has plants in Indiana
and Canada and sales offices in Holland and Poland. The fair value of assets
acquired and liabilities assumed were $21,222 and $7,341, respectively, with
$9,950 of goodwill recorded.
 
     On July 1, 1998, the Company acquired ATX, SA, a French manufacturer of IEC
hazard location lighting and related products, for approximately $25,680,
$16,580 of which was deferred and is payable in 2001. The fair value of assets
acquired and liabilities assumed were $8,805 and $1,503, respectively, with
$18,235 of goodwill recorded.
 
     The acquisitions were accounted for using the purchase method of
accounting. The results of operations of these businesses have been included in
the Company's consolidated results of operations since the respective dates of
the acquisitions. Had Easy Heat and ATX, SA been acquired as of the beginning of
the period, the unaudited pro forma net sales for the Company would have been
$580,533 and the unaudited pro forma net income would not have been
significantly different from reported amounts.
 
(3) RELATED-PARTY TRANSACTIONS
 
     During the regular course of business, the Company enters into arms-length
purchase and sales transactions with other companies affiliated with Emerson,
General Signal, and SPX and participates in cash pooling with certain of these
affiliated companies. At September 30, 1998, the Company had receivables from
and payables to such related parties totaling $25,245 and $4,433, respectively.
In addition, the Company was indebted to an affiliated company in the amount of
$9,693 for a promissory note, payable upon demand. The promissory note was
issued in connection with the acquisition of Easy Heat. The interest is payable
quarterly at the Canadian Dollar Bankers' Acceptance rate plus 5 basis points
and resets every 90 days. As of September 30, 1998, the interest rate was 5.05%.
Net interest income from affiliated companies for the fiscal year ended
September 30, 1998 was $1,220.
 
     For the year ended September 30, 1998, the Company paid $2,020 for
management services performed by Emerson.

                             (DOLLARS IN THOUSANDS)
 
(4) SHORT-TERM BORROWINGS -- AFFILIATE
 
     Short-term borrowings at September 30, 1998 consist of a promissory note,
payable upon demand in the amount of $9,693 issued by an affiliate of the
Company in connection with the acquisition of Easy Heat. The interest is payable
quarterly at the Canadian Dollar Bankers' Acceptance rate plus 5 basis points
and resets ever 90 days. As of September 30, 1998, the interest rate was 5.05%.
 
(5) INTEREST-BEARING OBLIGATION
 
     Interest-bearing obligation at September 30, 1998 represents a deferred
obligation arising from the acquisition of ATX, SA which is payable to the
seller in 2001. At September 30, 1998, the applicable interest rate was 3.60%.
 
(6) LONG-TERM DEBT
 
     Long-term debt at September 30, 1998 consists of a 5.625% Industrial
Revenue Bond (IRB) in the amount of $3,500, due December 1, 2002. Interest is
payable semiannually. Total interest paid related to long-term debt and other
interest-bearing obligations during the year ended September 30, 1998 was $487.
 
(7) FINANCIAL INSTRUMENTS
 
     The fair value of the Company's short-term financial instruments
approximate their carrying value due to their short-term nature. The fair value
of the Company's long-term debt approximates its carrying value, as the interest
rate is materially consistent with the rate that could be obtained as of
September 30, 1998.
 
(8) RETIREMENT PLANS
 
     The Company has various defined benefit pension plans covering
substantially all of its U.S. employees. Benefits are based on years of service
for the Company, including years of service for Emerson and General Signal, and
compensation. The cost of the plans is being funded currently. The actuarial
present value of benefit obligations and the funded status of the Company's
defined benefit pension plans as of September 30, 1998 follow:

obligation was 7.25%; the initial assumed health care cost trend rate was 7.0%,
declining to 4.5% in the year 2004.
 
     An increase in the assumed health care cost trend for each year by one
percentage point would increase the projected benefit obligation as of September
30, 1998 by $128 and increase the net postretirement benefit cost for the year
ended September 30, 1998 by $13.
 
(10) SUBSEQUENT EVENTS
