ITEM 1. BUSINESS
 
GENERAL
 
     Serv-Tech, Inc. (the "Company") is an integrated provider of specialty
services and products to process industries worldwide. Serv-Tech has three
primary operating segments: (i) Serv-Tech Specialty Services ("Specialty
Services"); (ii) SECO Industries, Inc. ("SECO"); and (iii) Environmental
Services and Performance Chemicals ("Environmental"). Specialty Services
provides total turnaround project management services including heat exchanger
extraction and cleaning, fabrication, specialty welding, refractory and other
specialized services primarily to the refining, petrochemical, paper, and power
industries. SECO provides specialty electrical and instrumentation contracting
services to the processing, petrochemical, power, pulp and paper, and food
processing industries. The Environmental business formulates specialty chemicals
to meet specific customer needs primarily in the hydrocarbon processing, pulp
and paper, and wastewater industries. Also included in Environmental is
specialty decontamination services provided primarily to the hydrocarbon
processing industry through the Company's subsidiary ST Environmental, and
refined-product and heavy oil tank cleaning services provided through Terminal
Technologies, Inc., a subsidiary of the Company.
 
     The Company was organized in Texas in 1978, to provide conventional
hydroblasting and chemical cleaning services to the refining, petrochemical and
paper processing industries in Texas and Louisiana. In 1985, the Company
introduced its new heat exchanger extraction and cleaning technologies and sold
its conventional businesses. In 1987, the Company introduced its tower and
vessel maintenance services to complement its heat exchanger services. In 1988,
the Company introduced its turnaround management services and its proprietary
tank cleaning services. Specialty pipe welding services were added in late-1990.
Electrical and instrumentation services were added in September 1991, with the
acquisition of SECO. The Company began offering engineering and design services
in May 1992, with the acquisition of Talbert & Associates, Inc. ("TAI"). In
1994, the engineering capabilities of TAI were incorporated into the newly
formed Serv-Tech EPC group, to offer its customers turnkey, single-source
responsibilities for engineering, procurement and construction services. In
1994, the Company introduced refractory services through the acquisition of
Hartney Industrial Services Corporation ("Hartney").
 
     In July 1996, the Company announced its intent to discontinue its
engineering, procurement and construction ("EPC") operations. The EPC operations
provided a full range of engineering, procurement and construction services
primarily to the refining, petrochemical and food processing industries. As of
July 1996, the discontinued EPC operations consisted of: (i) several domestic
EPC projects (which have now been completed); (ii) F.C. Schaffer and Associates,
Inc. ("Schaffer") which includes the Finchaa Sugar Factory project, expected to
be completed during the latter part of 1997 (see Discontinued EPC Operations
section below), and a consulting engineering practice; (iii) a construction
company in Orange, Texas (which has been closed and the majority of its
remaining assets sold); and (iv) engineering operations in Lake Charles and New
Orleans, Louisiana (which have been sold). See "Discontinued EPC Operations"
section below for additional information regarding these operations. With the
exception of the Finchaa project, all EPC operations have ceased.
 
MERGER
 
     On March 5, 1997, the Company entered into an Agreement and Plan of Merger
(the "Merger Agreement") by and among Philip Environmental Inc., an Ontario,
Canada corporation ("Philip"), Taro Aggregates Ltd., an Ontario, Canada
corporation and wholly-owned subsidiary of Philip ("Taro"), ST Acquisition
Corporation, a Texas corporation and wholly-owned subsidiary of Taro ("Sub"),
and the Company. Pursuant to the Merger Agreement, Sub will be merged with and
into the Company, and the Company will become a wholly-owned subsidiary of Taro
and an indirect, wholly-owned subsidiary of Philip.
 
     Under the terms of the Merger Agreement, each share of the Company's Common
Stock, par value $.50 per share ("Company Common Stock") will be exchanged for
0.403 share of Philip common stock, no
 
                                        1
   4
 
par value ("Philip Common Stock") (except for shares held by persons who perfect
and exercise dissenters' rights under Texas law), provided that Philip will pay
cash in lieu of any fractional shares of Philip Common Stock to which holders of
Company Common Stock would otherwise be entitled. Based upon the closing price
of Philip Common Stock on March 5, 1997, each share of Company Common Stock is
valued at $6.60 per share. In aggregate, the transaction is valued at
approximately $72.0 million, including the assumption of approximately $21.0
million of Company indebtedness. The transaction is subject to regulatory and
shareholder approvals, and is expected to close by June 30, 1997.
 
     Philip is a fully integrated, resource recovery and industrial services
company providing metals processing and mill services, solid and liquid
by-products recovery and industrial and remediation services to all major
industry sectors. Philip Common Stock trades on the New York Stock Exchange.
 
SPECIALTY SERVICES
 
     Specialty Service's principal market has been the petroleum refining
industry in the United States. Its customers include the majority of the ten
largest integrated oil companies and many of the large independent oil companies
in the United States. To ensure the operability, environmental compliance,
efficiency and safety of their refineries, these companies must periodically
maintain, repair or replace process equipment, operating machinery and piping
systems. Since 1986, increased demand for petroleum products and a stabilization
in refining capacity has led to a substantial increase in refinery utilization,
providing refineries with an incentive to minimize the duration of maintenance
turnarounds. Consequently, refineries have increased their reliance on outside
contractors who can perform specialized turnaround services within strict time
constraints.
 
     Planning and Management Services. As demand for the Company's specialized
heat exchanger, tower and vessel maintenance services increased, the Company
developed the planning capabilities, operational skills and field supervision
necessary to manage all aspects of a turnaround. When managing a turnaround, the
Company is responsible for scheduling and coordinating the entire project. In
addition, certain aspects of a turnaround, such as heat exchanger and tower and
vessel maintenance, refractory installation, piping repair and fabrication,
inspection and repair of furnaces and heaters, and certain specialized types of
welding are typically provided directly by the Company. The Company intends to
continue to enhance its capabilities in turnaround management by improving its
planning and estimating capabilities, adding additional services, and hiring
experienced, qualified project management.
 
     Heat Exchanger Services. Heat exchangers are essential components in
petroleum refining and petrochemical processing. Crude oil and other feedstocks
must be heated before they are processed. Once processed, finished or
semi-finished products must be cooled before storage. Refineries and
petrochemical plants use heat exchangers to allow hot products, which need
cooling, to give up their heat to crude oil or feedstocks which need heating.
This results in conservation of energy and reduced operating cost.
 
     Heat exchangers require periodic maintenance and cleaning, and are usually
cleaned in conjunction with a scheduled turnaround, which may involve the
removal and cleaning of up to 300 heat exchangers during a one- to four-week
period. During the turnaround, the heat exchangers are disassembled and tube
bundles are extracted, cleaned and inspected. The tube bundles are then
reinserted and the heat exchangers are reassembled and pressure tested.
 
     The Company extracts and reinserts heat exchanger bundles using its
patented Fast Draw(R) mobile heat exchanger bundle extractor. The Fast Draw(R)
unit uses a rotating carriage frame, which is aligned with the heat exchanger
centerline and attached to the exchanger shell. A pulling sled, situated on the
carriage frame, is attached to the bundle tubesheet. The pulling sled is then
activated and exerts a pulling force of up to 100 tons to extract the bundle
from the exchanger shell in one continuous, controlled pull. The carriage can be
adjusted to balance the bundle as it is extracted. Once the heat exchanger
bundle is fully extracted, it is lowered to a Company designed and owned trailer
for transportation to an approved cleaning site at the refinery. After cleaning
and inspection, the process is reversed to reinsert the tube bundle. The Company
has received four United States patents regarding its Fast Draw(R) technology.
See "-- Patents, Licenses and Permits."
 
                                        2
   5
 
     In 1985, the Company introduced its Fast Clean(R) system, a mobile,
self-contained, remotely controlled, high-pressure hydroblasting unit. By
cleaning multiple tubes at one time and eliminating hand-held hydroblasting
equipment, the Fast Clean(R) system has demonstrated significant improvements
from traditional methods in cleaning time, personnel safety and manpower
requirements. The Fast Clean(R) unit enhances operator safety by distancing
personnel from high pressure streams and replacing flexible hoses with rigid
piping. The units' mobility allows the Company to perform jobs at widely
separate locations with a minimum of moving costs. The Company has received
three United States patents regarding its Fast Clean(R) technology. See
"-- Patents, Licenses and Permits."
 
     The Company also provides the manpower and tools to disassemble and
reassemble heat exchanger components and shells. The Company has several fully
equipped tool trucks, which are used in conjunction with Fast Draw(R) and Fast
Clean(R) equipment. By combining the disassembly, extraction, cleaning,
reassembly and testing of the heat exchanger, the Company is able to control all
phases of heat exchanger maintenance and provide the customer with shorter
turnaround cycles.
 
     Tower and Vessel Maintenance. In 1987, Specialty Services expanded its
turnaround maintenance capabilities by offering tower and vessel maintenance
services. An integral part of all refining units, towers are used to separate
the components of crude oil or other hydrocarbons through distillation. The
distillation process utilizes a series of disc-shaped perforated horizontal
plates called trays, spaced about every two feet inside the tower. Since these
trays are exposed to high temperature and corrosive conditions during the
distillation process, and because these trays are critical to meeting product
specifications, towers are always inspected and repaired during maintenance
turnarounds. Frequently, tower maintenance is critical to completing the
turnaround and returning the unit to operation. Inspection, repair, modification
and replacement of the tower trays require an experienced work force to complete
the work within the strict time limits imposed by the customer. During the
turnaround, other towers, drums and vessels which are ancillary parts of the
refining process are opened, inspected and repaired if necessary. The Company
has assembled the necessary management, planning skills and labor force to offer
its customers a cost effective tower and vessel maintenance service.
 
     Specialty Pipe Welding. In late-1990, Specialty Services began offering,
through a newly formed subsidiary, ST Piping, Inc., specialized welding services
to refineries and petrochemical plants. The piping, vessels and heat exchangers
in these plants must be designed to withstand extreme high temperature, pressure
and corrosive conditions. Many of the newer process designs utilize high alloy
steels and exotic metals. ST Piping has the equipment and highly skilled
personnel necessary to provide the specialized welds needed for these design
conditions. All of ST Piping's work conforms to the American Society of
Mechanical Engineers Boiler and Pressure Vessel Code, the highest standards in
the industry.
 
     Refractory, Acid Proof and Fireproof Construction. In 1994, Specialty
Services began offering refractory installation and maintenance services through
Hartney, which was acquired in June 1994. Hartney is a leading provider of
refractory services for turnarounds, outages, revamps and expansions of critical
processing units primarily for the petroleum refining, chemical processing and
power industries. Refractory services include the construction of high
temperature, corrosion resistant and fireproof lining systems for virtually
every type of industrial application, in-plant structural and vessel
fireproofing and major refractory installations on Fluid Catalytic Cracking
Units.
 
SECO
 
     In September 1991, Serv-Tech acquired SECO, a specialty contracting company
engaged primarily in electrical and instrumentation projects. SECO's clients are
primarily petroleum, petrochemical, paper, food processing, mining, marine and
utility companies as well as major engineering firms and general contractors.
 
     SECO was formed in 1961, as an electrical contractor in southern Louisiana.
SECO's initial growth was in the oil field and commercial markets and was
characterized by progressively larger projects and wider geographical scope. At
present, a major portion of SECO's projects involve electrical and
instrumentation systems installation for large offshore petroleum production
facilities. SECO provides its services throughout the world and has worked in 21
countries.
 
                                        3
   6
 
     Offshore production platforms, petroleum refineries and petrochemical
processing plants, mining facilities, and other industrial installations have
complex requirements for electrical, instrumentation, power distribution and
process control systems. Installations of these systems involve large
construction projects often characterized by multiple fabrication sites, wide
diversity of components and processes, and application of advanced technology.
The electrical and instrumentation contractor must excel in every phase of the
project from design assistance to final hook-up.
 
     SECO begins a project by identifying a project management team, which
reviews the project's scope and specifications, and develops a construction
schedule. Project personnel, including engineers, supervisors, foremen and
craftsmen, are assigned to the project. Weekly schedules are developed through
the joint efforts of the project management team and crew foremen, and progress
against the schedules is closely monitored. In addition, inspections of each
task are conducted to assure compliance with customer specifications and
industry codes. SECO's activities are labor intensive, and the ability to
assemble the right number and mix of skilled craftsmen is critical to project
success. Individual projects may require staffing levels of over 150 craftsmen.
 
     During 1994, SECO diversified into the areas of clean-fuels projects (Mobil
Oil Clean Fuels project in Torrance, California), food processing (carrots in
California; rice and salt in Louisiana) and riverboat casinos. In 1995 and 1996,
SECO executed two large oil production projects, the Shell Mars and Ram Powell
deep-water production platforms. SECO is currently involved in the Shell Ursa
deep-water production platform project. The operations of SECO are expected to
continue to include deep-water production platform projects as well as continued
diversification into food processing, petrochemical and other industries.
 
ENVIRONMENTAL SERVICES AND PERFORMANCE CHEMICALS
 
     In 1988, Serv-Tech introduced petroleum storage tank sludge cleaning
services, which significantly enhance personnel safety and reduce the
environmental risks of cleaning petroleum storage tanks. Sludge is a mixture of
hydrocarbons (paraffins and asphaltines), sediment and corrosive elements which,
together with water, form an emulsion of oil, water and solids. Generally, more
than 90 percent of the sludge constitutes valuable hydrocarbons. Sludge is
generally heavier and more viscous than oil and settles to the bottom of the
tank, thereby reducing the effective capacity of the tank and increasing the
likelihood of corrosion of the tank bottom, which can lead to leakage into the
environment.
 
     The Company's petroleum tank cleaning services utilize the HP2000 system, a
high-pressure rotating, controllable submerged jet that is inserted into a tank
while the tank remains in service. The twin nozzle, high-shear unit is
positioned at the center of the tank and directs single or opposed jets of crude
oil horizontally across the tank bottom. The high-pressure sweeping action
resuspends the hydrocarbon components of the sludge by breaking the bonding
within the emulsion. Once suspended, the sludges and crude oil are filtered
through fine mesh screens on Company owned filter trucks to further homogenize
the crude oil and remove any sediment and rust scale. A refinery can then
process the resuspended hydrocarbon in the normal manner. Inorganic sediments,
scale and water remaining in the tank will have to be removed using traditional
methods. However, because the volume of the sludge has been reduced, the time
between such cleanups is significantly increased.
 
     The primary benefits of the Company's petroleum tank cleaning services are
the recovery of hydrocarbons from the resuspended sludge, the minimizing of
vapor emissions associated with the removal of the residual sludge from the
tank, enhancement of worker safety by reduced exposure to hazardous conditions,
and reduction in the volume of sludge and other waste that requires
reprocessing, disposal in landfills or incineration.
 
     In December 1991, the Company acquired the business operations of TTI, a
provider of tank cleaning services for product storage tanks in petroleum
products distribution terminals. TTI's tank cleaning process uses that company's
patented Hydrocarbon Reclaimer System. The Hydrocarbon Reclaimer System filters
the contaminated tank bottoms, recovering all of the reusable product. The waste
material collected in the filtering process is dried and stored in containers
supplied by TTI. All waste generated in the tank-cleaning process
 
                                        4
   7
 
leaves the product distribution terminal as a dried solid. An advantage of the
process is that the waste solids are non-hazardous, and can be transported and
disposed by the customer with a minimum of permitting.
 
     During the first quarter of 1991, the Company acquired a 50-percent
interest in Chemisolv and acquired the remaining 50-percent interest in the
fourth quarter of 1994. Chemisolv is an environmental services and specialty
chemical treatment company with operations in the United Kingdom and the United
States. Management of this company has significant experience in providing
waste-stream treatment and chemical treating solutions to a wide range of
industries including food, hydrocarbon processing, textiles, metal finishing,
and pulp and paper.
 
     In 1992, the Company and Chemisolv jointly developed a proprietary chemical
decontamination process for removing benzene and other hydrocarbons from process
equipment in refineries and petrochemical plants. The Life Guard(R) system
utilizes chemical formulations developed by the Company and Chemisolv to
emulsify and extract hydrocarbons remaining in heat exchangers, towers and
vessels after those units have been removed from service in preparation for
turnaround maintenance. The emulsified solution containing the entrapped benzene
and hydrocarbons is then separated to allow disposal of the contaminants through
the plant's waste treatment facilities. The Life Guard(R) chemicals are
non-toxic and biodegradable.
 
     The benefits of the Life Guard(R) system are twofold: it improves worker
safety by removing harmful, carcinogenic benzene and other hydrocarbon compounds
from vessels in which maintenance is performed; and, it reduces the time
necessary to remove oil, sludges and hydrocarbons from process equipment. This
reduces turnaround time by permitting quicker entry to vessels, eliminating the
need for fresh air respiratory equipment, and providing cleaner work areas. On
turnarounds in which the Life Guard(R) system has been used, the Company has
experienced significant savings in time and manpower requirements. Turnaround
times have been reduced by one to three days and manpower has been reduced up to
25 percent.
 
     The Company manufactures pumping systems, which circulate the Life Guard(R)
chemical solutions. The Company has received one United States patent and two
United States patents are pending regarding its Life Guard(R) Decontamination
System. See "-- Patents, Licenses and Permits."
 
DISCONTINUED EPC OPERATIONS
 
     The Company introduced engineering services in May 1992, with the
acquisition of TAI, an engineering and design firm primarily serving the
petroleum refining and chemical industries. TAI provided a full range of
engineering, design, project management, drafting and estimating services. Since
the physical plants utilized by the Company's customers are large and complex,
they require specialized engineering services in order to undertake
refurbishment, expansion or new construction projects. TAI was able to perform
such jobs, beginning with field inspection activity, through total project
management, which included mechanical, civil, structural, electrical, process
and instrumentation engineering.
 
     In 1994, the engineering capabilities of TAI were incorporated into the
newly-formed Serv-Tech EPC group to offer its customers turnkey, single-source
responsibility for engineering, procurement and construction services. In
November 1994, EPC was awarded an estimated $20.7 million contract to design,
procure and construct a tank farm for Conoco in Westlake, Louisiana. This
project was completed in mid-1996.
 
     During the last part of 1994, the Company acquired all of the outstanding
common stock of Schaffer of Baton Rouge, Louisiana. Schaffer is one of the
leading experts on sugar mill design, engineering and construction management.
In February 1995, Schaffer secured a $83.0 million contract to design, procure
and construct a 4,000 metric-ton-cane-per-day sugar factory and 45,000
liter-per-day ethanol plant in Finchaa, Ethiopia. The project, which is financed
by the African Development Bank, is expected to be completed in the latter part
of 1997, followed by a twelve-month training and warranty period. At December
31, 1996, the Finchaa project was approximately 80 percent complete.
 
     Engineering, procurement and construction projects are typically of longer
duration with more predictable manpower levels than the Company's specialty
services work. Gross profit margins on construction contracts, however, are
lower than specialty services due to the better defined design and scope of work
and less critical nature of completion schedules compared to specialty services
projects.
 
                                        5
   8
 
     In July 1996, the Company announced its intent to discontinue its
engineering, procurement and construction ("EPC") operations. At July 1996, the
discontinued EPC operations consisted of: (i) several domestic EPC projects
(which have now been completed); (ii) Schaffer, which includes the Finchaa Sugar
Factory project as well as a consulting engineering practice; (iii) a
construction company in Orange, Texas (which has been closed and the majority of
its remaining assets sold); and (iv) engineering operations in Lake Charles and
New Orleans, Louisiana (which have been sold). With the exception of the Finchaa
project, which is expected to be completed during late-1997, all EPC operations
have ceased.
 
BUSINESS SEGMENT FINANCIAL INFORMATION
 
     For certain financial information relating to each of the Company's
operating segments, see Note 15 of Notes to Consolidated Financial Statements.
 
CUSTOMERS AND MARKETING
 
     The Company derives most of its revenues from continuing operations from
the refining and oil and gas production industries in the United States.
Services have also been provided to companies in the petrochemical, chemical,
gas processing, pipeline and liquid terminal industries. The Company's customers
operate through various subsidiaries and at multiple plant locations principally
throughout the United States. In general, decisions to award work are made at
each operating facility of the customer.
 
     In each of Serv-Tech's service lines, work is typically bid on a job-by-job
basis. Performance of services by the Company at any single plant or project
location does not assure the Company subsequent work at that facility or other
facilities of that customer. Conversely, the loss of a bid for any one project
does not affect the Company's ability to obtain additional work from that
customer. Chevron USA, Inc. accounted for 15 percent of the Company's revenues
from continuing operations in 1996 and 14 percent in 1995, and Mobil Oil
Corporation accounted for 29 percent of the Company's revenues from continuing
operations in 1994. The following table sets forth the Company's ten largest

     The Company maintains close contact with its customers and reviews
available industry information in order to determine upcoming projects for which
its services may be required. The Company generally is required to bid
competitively for work on a project-by-project basis for each of the services it
provides. Depending on the size and complexity of the work to be awarded, bid
lead times range from two weeks to four months. Much of the work involved in
preparing a bid consists of planning the schedule for the project. As a result,
costs associated with the planning, as well as anticipated costs for management
of the project, are included in the Company's bid. Bids are generally awarded
based on price considerations, although scheduling, efficiency, quality and
safety are also considered by the customer in awarding contracts.
 
     The Company's fee arrangements for its services are primarily based on
either detailed time and material billing schedules or are fixed-price based.
The Company has encouraged its customers to seek firm-bid turnkey proposals for
its Specialty Services contracts. Management believes that firm-bid contracts
permit its customers to realize the benefits of the Company's services and offer
the Company an opportunity to realize
 
                                        6
   9
 
higher profit margins. Time and material billing arrangements provide for
cost-plus billing schedules for labor and equipment used on the job and offer
the Company an assured level of project profitability. The accumulated man hours
and equipment utilized are billed on a weekly or monthly basis. In 1996,
approximately 78 percent of the Company's revenues were derived from time and
material contracts (versus fixed-price). A new pricing method, "performance
pricing", developed by the Company's Specialty Services group, involves
contractual arrangements with the customer based on performance, considering the
benefits of the Company's expertise, including reducing refinery downtime,
increased efficiency and improved safety.
 
     The Company maintains estimators and planners who review the scope of work
to be performed, analyze labor and material requirements, and prepare bids to be
submitted to potential customers. Final bid prices on major proposals are
coordinated between the estimator/planners, regional managers and senior
management.
 
     The Company markets its turnaround services through five regional offices
and its corporate headquarters in Houston, Texas, with its regional managers
primarily responsible for their sales effort. SECO services are marketed through
offices in Metairie, Louisiana, and five regional offices. The Company markets
its environmental services and performance chemicals from its Houston, Texas,
Atlanta, Georgia, and Manchester, England, offices.
 
PATENTS, LICENSES AND PERMITS
 
     The Company is the holder of 19 United States patents covering its Fast
Draw(R), Fast Clean(R), Life Guard(R) Decontamination System and tank cleaning
equipment and technology. The Company is actively developing technology related
to its businesses and has filed several patent applications with the United
States Patent Office. Management believes that the development of proprietary
technology has been an important factor in the Company's growth and the Company
intends to seek additional patent protection where appropriate. However, there
can be no assurance that additional patents will be granted, or as to the
validity or value of such patents. In addition, it is conceivable that
competitors could modify the essential technology represented by the Company's
patents in such a way that it would not result in patent infringement. The
Company's patents expire at various dates between November 18, 2003, and May 10,
2015.
 
     The Company is certified by the American Society of Mechanical Engineers
("ASME") Boiler and Pressure Vessel Code to hold "A", "U", "S", and "PP" stamps,
as well as the National Board "R" stamp. These stamps permit the Company to
perform specialized major weld repairs, nozzle replacements and additions in
compliance with ASME requirements.
 
BACKLOG
 
     Revenue backlog for SECO was $29.1 million, $17.1 million, and $18.0
million as of December 31, 1996, 1995 and 1994, respectively. Revenue backlog at
December 31, 1996, includes $9.4 million related to the Shell URSA project and
$6.0 million related to an additional deep-water drilling platform project, on
which work is scheduled to start in late-1997 and early-1998, respectively.
Backlog for the other operating groups is not meaningful due to the short lead
time and duration of the projects.
 
     While backlog can be an indication of expected future revenues, backlog is
subject to revisions from time-to-time due to cancellations, modifications and
changes in the scope of projects or their design and construction schedules.
There can be no assurance whether or when backlog will be realized as revenue.
 
COMPETITION
 
     The market for the Company's specialty and environmental services is highly
fragmented and competitive. Many of the Company's competitors have greater
financial and other resources than does the Company. Additionally, the Company
competes with numerous small, independent contractors, which collectively have a
significant share of the market for these services. Competitive factors for
these services include price considerations, performance record, quality and
safety.

GOVERNMENT REGULATION
 
     The Company's services involve contact with crude oil and refined petroleum
products. These substances have been classified as hazardous waste. Under
various federal laws, hazardous waste is regulated from the point of generation
until disposal. In addition, the United States Environmental Protection Agency
has issued regulations for hazardous-waste generators, transporters and owners
and operators of treatment, storage and disposal facilities.
 
     The Company's services are structured to avoid any involvement in the
disposal of hazardous wastes, and the Company does not consider itself to be a
generator or transporter of hazardous waste. Typically, all hazardous materials
handled by the Company are disposed of by the customer using the customer's
waste-disposal facilities. The cleaning of heat exchangers is usually performed
on cleaning slabs, with the water and debris collected and treated by the
customer's wastewater facilities. The Company has designed and installed for
several of its customers a closed-loop system to circulate and filter water used
in its Fast Clean(R) system. This minimizes water usage and reduces the volume
of wastewater processed by the customer. The Company's petroleum tank cleaning
and sludge control systems resuspend sludge within the petroleum storage tank,
permitting the refinery to reclaim processible hydrocarbons, rather than
removing the sludge for reprocessing or disposal. The Company's tank cleaning
services for petrochemical product storage tanks employ the patented Hydrocarbon
Reclaimer System which recovers all of the reusable product. All waste generated
by this process is in the form of non-hazardous dried solids, which can be
conveniently transported and disposed by the customer.
 
     All of the Company's operations are subject to regulations issued by the
Department of Labor under OSHA. These regulations have strict requirements for
protecting personnel involved with any materials that are classified as
hazardous, which includes certain materials found in heat exchangers, towers,
vessels and petroleum storage tanks. Violations of these rules can result in
fines and suspension of licenses.
 
INSURANCE
 
     The Company maintains a comprehensive property and casualty risk management
program. This program includes statutory worker's compensation insurance in
accordance with various states requirements and general liability insurance with
an occurrence annual aggregate coverage limit of approximately $100 million. The
Company's general liability insurance, although comprehensive, provides only
limited coverage for pollution-related claims and excludes fines and penalties
levied against the Company as a result of any violations by the Company of the
regulations issued by the Department of Labor under OSHA. To date, the Company
has not incurred significant fines or penalties or any liability for pollution,
environmental damage, toxic torts or personal injury from exposure to hazardous
wastes. However, a successful liability claim for which the Company is only
partially insured or completely uninsured could have a material adverse effect
on the Company. In addition, if the Company experiences a significant amount of
such claims, increases in the Company's insurance premiums could materially and
adversely affect the Company. Any difficulty in obtaining insurance coverage
consistent with industry practice may also impair the Company's ability to
obtain future contracts, which in most cases, are conditioned upon the
availability of specified insurance coverage.
 
WORKING CAPITAL
 
     The Company's customers typically compensate the Company for services
performed upon completion of a given project or on an agreed upon progress
payment schedule for larger projects. Therefore, the Company must have
sufficient working capital to permit it to undertake its services throughout the
duration of a project. The Company believes that its present working capital
position, combined with forecasted cash flows and borrowing capacity, will be
sufficient to meet the Company's working capital requirements. See Note 5 of
Notes to Consolidated Financial Statements for further discussion of the
Company's working capital facility.
 
QUARTERLY FLUCTUATIONS
 
     The Company's revenues and operating income have historically been subject
to significant, seasonal fluctuations with respect to its Specialty Services and
Environmental groups. This is due primarily to the
 
                                        8
   11
 
timing of shutdowns at plant facilities. Accordingly, it is anticipated that the
Company's quarterly results will fluctuate, and the results of one quarter
should not be deemed to be representative of the results of any other quarter or
for the year.
 
EMPLOYEES
 
     At December 31, 1996, the Company had 969 full-time employees, of which 173
were salaried and 796 were hourly. In addition, the Company employs hourly
workers on an as-required basis to perform labor on a job-by-job basis. Total
employment levels have ranged from 639 to 1,267 per week during 1996, averaging
1,059 employees on a weekly basis. The number of employees fluctuates
significantly due to changing demand during the peak turnaround periods. The
Company has been able to staff its projects through maintenance of a
computerized listing of qualified workers and the personal contacts of its
superintendents and foremen. The Company's two union subsidiaries maintain
collective bargaining agreements with several construction trade unions.
Management believes its relations with its employees to be good.
 
ITEM 2. PROPERTIES
 
     The Company's corporate offices are located at 5200 Cedar Crest Boulevard
in Houston, Texas, at a Company-owned combination office and operations
facility. This location contains 15,000 square feet of office space and 72,500
square feet of shop facilities. SECO occupies 27,500 square feet of leased
property located in Metairie, Louisiana. The Company leases an aggregate of
approximately 200,000 square feet of office, shop and storage space in Lake
Charles, Baton Rouge and Lafayette, Louisiana; Beaumont and Houston, Texas;
Atlanta, Georgia; and Los Angeles, California. The Company does not anticipate
any difficulty in renewing those leases that require renewal within the next
five years. The Company owns land and buildings containing an aggregate of
approximately 50,000 square feet of office and shop space in Houston, Texas; and
Westlake and Belle Chasse, Louisiana. The Company believes that its existing
facilities are adequate to meet the requirements of current operations and that
suitable additional space will be available as required to accommodate any
expansion of operations.
 
     The Company designs, engineers and assembles the Fast Draw(R), Fast
Clean(R), Tank Cleaning, and Chemical Decontamination equipment at its Westlake,
Louisiana facility. The Company assembles this equipment from components that it
purchases from outside suppliers or which it fabricates. The Company has several
sources for these components and does not rely upon any single supplier.
 
ITEM 3. LEGAL PROCEEDINGS
 
     The Company is involved in various claims and disputes incidental to its
business. The Company believes that the disposition of all such claims and
disputes, individually or in the aggregate, should not have a material adverse
effect upon the Company's financial position, results of operations or cash
flows.

date was $5.25. The Company has not paid dividends on its common stock, and the
Board of Directors of the Company presently intends to continue a policy of
retaining earnings for use in the Company's operations and to fund the Company's
working capital requirements and growth opportunities.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS
 
     The following discussion should be read in conjunction with the
Consolidated Financial Statements and related notes thereto included elsewhere
in this Report.
 
CONTINUING OPERATIONS
 
     The year ended December 31, 1996 net loss from continuing operations of
$2.5 million, or $0.37 per share, includes a $2.3 million, or $0.35 per share
charge for the impairment of certain equipment that will no longer be utilized
in the future operations of the Company, the write-off of an uncollectible
receivable and severance related costs. Additionally, included in the 1996 loss
is $5.8 million ($3.9 million, or $0.57 per share, on an after-tax basis), of
net proceeds from the Stewart & Stevenson settlement (see Note 8 of Notes to
Consolidated Financial Statements). Excluding the effects of these two items,
the Company generated a net loss from continuing operations of $4.0 million, or
$0.60 per share, compared to a net loss of $0.8 million, or $0.11 per share in
1995, and a net loss of $9.3 million, or $1.52 per share, in 1994. The 1994 net
loss includes a special charge of $10.0 million, or $1.64 per share. Excluding
the effect of the special charge, the Company generated net earnings from
continuing operations in 1994 of $0.7 million, or $0.12 per share.
 
     Consolidated revenues for 1996 decreased 26.9 percent to $142.4 million
from $194.8 million in 1995, which was 16.1 percent higher than 1994
consolidated revenues of $167.8 million. The 1996 decrease in revenues was
attributable primarily to lower levels of activity in the specialty turnaround
maintenance business, Specialty Services, resulting from delays in scheduled
maintenance at refinery facilities. The increase in 1995 was due to increased
levels of activity in Specialty Services and the Company's Environmental and
Performance Chemicals business, which provides tank cleaning, decontamination
services and specialty chemicals.
 
     Consolidated gross profit margins as a percentage of revenues were 21.0
percent for 1996, increasing from 1995 margins of 18.8 percent. This increase in
gross profit margins was due primarily to improved Specialty Services project
mix, management and performance. The 1995 consolidated gross profit margin
increased from 17.2 percent in 1994. This increase was mainly attributable to
improved Specialty Services and Environmental and Performance Chemical profit
margins over 1994.
 
     Consolidated selling, general and administrative expenses for 1996 of $35.8
million include a pre-tax charge of $3.5 million, discussed above. Excluding
this charge, 1996 overhead expenses decreased $2.0 million, or 6.0 percent to
$32.3 million in 1996 from $34.3 million in 1995. The decrease is lower than the
26.9 percent decrease in revenue for the same period due to the level of fixed
overhead costs inherent in the business which do not decrease with lower revenue
levels. Consolidated selling, general and administrative expenses in 1995 were
$8.3 million, or 32.1 percent, higher than the 1994 level of $26.0 million,
resulting primarily from the expansion of the Specialty Services and the
Environmental and Performance Chemical businesses. The expansion of the
Specialty Services business included the acquisition of Hartney Industrial
Services ("Hartney") in June 1994.
 
     Interest expense increased in 1996 to $2.4 million compared to $1.9 million
in 1995. See Note 5 of Notes to Consolidated Financial Statements for discussion
of the restructuring of the Company's debt and the related increase in interest
costs. In 1995 interest expense increased $0.5 million from $1.4 million in
1994. These increases are due to a higher level of working capital borrowings
under the Company's revolving line of credit necessary to support the Company's
level of business activity.
 
     Interest income increased in 1996 to $0.1 million following a decrease in
1995 from 1994 of $0.5 million. The 1996 increase was primarily due to interest
income generated on the Stewart & Stevenson settlement proceeds. The 1995
decrease resulted primarily from lower available cash balances during the year.
 
     In 1996, other income of $5.9 million includes the net effect of the
Stewart & Stevenson litigation settlement which the Company received during the
year. After payment of attorney's fees and a payment to the Company's founder,
Richard W. Krajicek, the Company received and recorded a $5.8 million net
settlement, or $3.9 million on an after-tax basis (see Note 8 of Notes to
Consolidated Financial Statements).
 
                                       12
   15
 
     Minority interest includes the minority shareholders portion of ST Piping,
Inc. ("ST Piping") earnings. Effective May 18, 1995, the Company acquired an
additional 20 percent of the outstanding common stock of ST Piping, Inc. from
the minority shareholders of that company. Prior to the acquisition, the Company
owned 70 percent (see Note 4 of Notes to Consolidated Financial Statements). The
reduced level of minority ownership in ST Piping coupled with its reduced level
of earnings in 1996 as compared to 1995, due to the lower levels of specialty
turnaround maintenance activity during 1996, have caused the decrease in
minority interest in 1996. Minority interest in 1995 increased over 1994 due to
a higher level of ST Piping earnings in 1995.
 
SPECIALTY SERVICES
 
     In 1996, Specialty Services revenues decreased $52.9 million, or 40.1
percent from 1995 revenues of $131.9 million. Specialty Services revenues
increased $18.3 million, or 16.1 percent, in 1995 over 1994 revenues of $113.5
million. The 1996 revenue decrease was attributable to lower levels of business
activity throughout the turnaround maintenance business, resulting from delays
in scheduled maintenance at refinery facilities which were experiencing improved
margins. The increase in 1995 was mainly due to the acquisition of Hartney in
June 1994, which generated revenues of $21.6 million in 1995, coupled with
increased refinery spending during the year.
 
     Operating income of $0.1 million in 1996 includes a $1.4 million pre-tax
charge for the impairment of certain obsolete equipment and the write-off of an
uncollectible receivable. Excluding the effect of this charge, operating income
was $1.5 million compared to $4.7 million in the prior year. This decrease is
consistent with the reduced levels of turnaround maintenance revenues as
discussed above. Operating income in 1995 was $1.0 million lower than the 1994
level of $5.7 million, excluding a $10.6 million pre-tax special charge recorded
during 1994. Higher levels of revenues and gross profit in 1995 were offset by
increased selling, general and administrative expenses. The increased level of
overhead expenses was attributable primarily to the acquisition of Hartney in
June, 1994.
 
SECO
 
     SECO revenues were $50.0 million in 1996, a decrease of $2.2 million from
1995 revenues of $52.2 million. In 1995, revenues increased 5.6 percent from
1994's level of $49.4 million. The 1996 decrease in revenue is attributed to
decreased activity in onshore projects, due to a reduced number of refinery
turnaround projects in 1996, as discussed above, offset partially by an increase
in offshore drilling platform revenue. Revenues from deepwater drilling platform
installations were $10.1 million, $7.1 million and $1.3 million for 1996, 1995
and 1994, respectively. In October 1996, SECO was awarded a contract for work on
the deck module fabrication of the Shell URSA tension leg platform, currently
scheduled for completion in July 1998. Revenues for 1996 included only $0.1
million attributable to the Shell URSA project.
 
     Operating income amounted to $3.5 million in 1996, a decrease of 4.8
percent from the 1995 level of $3.7 million. However, operating income as a
percentage of revenue remained at 7.1 percent for both periods. Operating income
increased by $0.3 million in 1995 from $3.4 million in 1994. This increase is
consistent with the increased level of revenue experienced in 1995.
 
     Revenue backlog was $29.1 million, $17.1 million, and $18.0 million as of
December 31, 1996, 1995 and 1994, respectively. Revenue backlog at December 31,
1996, includes $9.4 million related to the Shell URSA project and $6.0 million
related to an additional deep-water drilling platform project, on which work is
scheduled to start in late-1997 and early-1998, respectively. While backlog can
be an indication of expected future revenues, backlog is subject to revisions
from time-to-time due to cancellations, modifications and changes in the scope
of projects or their design and construction schedules. There can be no
assurance whether or when backlog will be realized as revenue.
 
ENVIRONMENTAL AND PERFORMANCE CHEMICALS
 
     Environmental and Performance Chemicals 1996 revenues remained constant
with the 1995 level of $16.4 million. In 1995, revenue increased $7.8 million,
or 90.6 percent from $8.6 million in 1994. Chemisolv
 
                                       13
   16
 
Holdings ("Chemisolv"), the Company's performance chemical subsidiary acquired
in November 1994, contributed $5.1 million to the increase in revenues. The
remaining $2.7 million increase was attributable to increased activity in the
Company's tank cleaning services.
 
     The $1.4 million operating loss in 1996, includes a $0.7 million pre-tax
charge for the write-off of certain tank cleaning equipment that will not be
utilized in the future operations of the Company. Excluding the effects of this
charge, the operating loss of $0.7 million was down $1.0 million from 1995
operating income of $0.2 million. This reduction was due to increased research
and development expenditures related to the development of the new
paper-strengthening technology, Mastiff (SM). Operating income in 1995 increased
$0.4 million from a $0.2 million loss in 1994. Higher gross profit margins
recognized on decontamination services and increased activity in the tank
cleaning business contributed to the improved operating results which were
partially offset by Chemisolv operating losses.
 
CORPORATE AND OTHER
 
     The operating loss of $8.0 million includes a $1.3 million pre-tax charge
primarily for severance related costs and some consulting and professional fees.
Excluding this charge, the 1996 operating loss of $6.7 million increased $0.4
million from 1995. This increase is mainly attributable to costs related to
professional services necessary to study and identify strategic alternatives
available to the Company. These expenses were incurred during the latter part of
1996.
 
DISCONTINUED OPERATIONS
 
     In July 1996, the Company announced its intent to discontinue its
engineering, procurement and construction ("EPC") operations. The EPC operations
provided a full range of engineering consultation and project management
services primarily to the refining, petrochemical and food processing
industries. The discontinued EPC operations consisted of, (i) several domestic
EPC projects (which have now been completed), (ii) F.C. Schaffer and Associates,
which includes the Finchaa Sugar Factory project as well as a consulting
engineering practice, (iii) a construction company in Orange, Texas (which has
been closed and substantially all remaining assets have been sold) and (iv)
engineering operations in Lake Charles and New Orleans, Louisiana (which have
been sold).
 
     The 1996 net loss from discontinued operations of $10.3 million (net of
income tax benefit of $4.4 million), or $1.54 per share, included a $9.7 million
($6.6 million, or $0.99 per share, on an after-tax basis) charge primarily for
the write-down of the profitability on several domestic EPC projects and the
Finchaa Sugar Factory project. The Finchaa project was written down to a $4.5
million loss ($2.9 million, or $0.43 per share, on an after-tax basis) during
the fourth quarter. Excluding the effects of this charge, the net loss from
discontinued operations was $3.7 million, or $0.55 per share for 1996 compared
to net income of $2.8 million (net of income tax expense of $0.7 million), or
$0.42 per share for 1995 and net income of $0.5 million (net of income tax
expense of $0.1 million), or $0.08 per share for 1994.
 
     Additionally, in conjunction with the decision to discontinue the EPC
operations, the Company recorded a $4.3 million (net of income tax benefit of
$1.0 million), or $0.64 per share, estimated loss on disposal of the EPC
operations for the estimated loss on sale and disposal of certain EPC divisions
and the related write-off of goodwill. The estimated loss on disposal of the EPC
operations includes a $0.3 million, or $0.05 per share, estimated loss during
phase-out period.
 
     Net current assets from discontinued operations at December 31, 1996
consisted primarily of working capital associated with the Finchaa project and
the consulting engineering practice of F.C. Schaffer and Associates. Net
non-current assets from discontinued operations consisted primarily of property
and equipment, net of a note payable of $0.7 million.
 
     Revenues generated by the discontinued EPC operations for 1996, 1995 and
1994 were $70.3 million, $84.7 million and $13.3 million, respectively. 1996 and
1995 revenues included $38.9 million and $32.8 million related to the Finchaa
Sugar Factory Project, respectively.

   17
 
FINCHAA SUGAR FACTORY PROJECT
 
     During the first quarter of 1995, F. C. Schaffer & Associates ("Schaffer"),
a subsidiary of the Company, secured an $83 million contract to engineer,
design, procure and construct a 4,000 metric ton cane-per-day sugar factory and
45,000 liter-per-day ethanol plant in Finchaa, Ethiopia. The project, which is
financed by the African Development Bank, is expected to be completed in the
latter part of 1997 followed by a twelve month warranty and training period. In
conjunction with the effectiveness of the contract, the Company received an
advance payment equal to 20.0 percent of the contract value. The Company has
issued letters of credit to support performance and the 20.0 percent advance
payment. At December 31, 1996, letters of credit of $6.3 million were
outstanding to support the unrecovered portion of the advance payment and $8.3
million to support project performance guarantees, see Note 5 of Notes to
Consolidated Financial Statements. Contractual payment amounts to Schaffer are
supported by a revolving letter of credit issued by the Ethiopian government via
the African Development Bank.
 
     As of December 31, 1996, the Finchaa project was approximately 80 percent
complete.
 
VOLATILITY AND SEASONALITY OF REVENUES
 
     Specialty Services revenues and operating income are subject to significant
quarterly fluctuations, affected primarily by the timing of planned shutdowns at
its customers' facilities. In general, scheduled turnarounds fall predominantly
in two seasonal periods -- February through April, and September through
November. The exact timing and duration of these periods will largely depend on
the demand for the customers' products. In addition, most of the Specialty
Services contracts are short in duration, and large individual contracts may
significantly influence results in any specific quarter.
 
OTHER
 
     The Company has a combination of contractual and discretionary bonus
programs for key personnel throughout most of its operating groups. Payments
under discretionary plans total, in the aggregate, approximately eight percent
of operating earnings of each unit. For the turnaround maintenance division of
Specialty Services and the Chemisolv division of Environmental and Performance
Chemicals, the Company has established contractual profit sharing programs in
lieu of the discretionary programs noted above. The Specialty Services and
Chemisolv programs generally provide for a profit sharing pool to be established
equal to 20.0 percent of the fully-burdened operating earnings of the respective
group.
 
IMPACT OF INFLATION AND CHANGING PRICES
 
     Inflation and changing prices have not significantly affected the Company's
operating results or the markets in which the Company performs services.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Capital expenditures for 1996, excluding acquisitions, were $2.0 million,
primarily for the purchase of equipment necessary to support the operations and
expansion of the Company's operating groups. Capital expenditures for 1997,
excluding acquisitions, are expected to be approximately $1.5 million, primarily
for the purchase and manufacture of equipment to support the Company's business
activities.
 
     At December 31, 1996, the Company's working capital totaled approximately
$8.2 million. The Company has been able to finance its working capital
requirements through its cash flows from operations and bank borrowings. The
Company maintains a $26.5 million revolving line of credit with two banks (the
"Revolver"), which expires in December 1997. The $26.5 million credit facility
decreases to $23.5 million at April 30, 1997, and $19.5 million at June 30,
1997. At December 31, 1996, $5.6 million was outstanding under the revolving
line of credit. Additionally, the Company has irrevocable letters of credit
totaling $4.6 million outstanding to guarantee certain of the Company's
insurance programs and bid bonds, leaving $16.3 million available for borrowing
under the Revolver. However, subsequent to December 31, 1996, the Company has
drawn approximately $12.9 million against the revolving line of credit in order
to fund working capital requirements
 
                                       15
   18
 
consistent with increased first quarter 1997 revenue activity. These amounts are
expected to be repaid during the second quarter of 1997 as receivables are
collected from the seasonably high point of the Company's turnaround maintenance
business. In addition, the Company has $15.0 million in Senior Notes Payable due
June 2003 (See Note 5 of Notes to Consolidated Financial Statements).
 
     As a result of the fourth quarter 1996 net loss, the Company was in
violation of various financial covenants. The Company received waivers from its
lenders with respect to such covenant violations as well as waivers necessary to
enter into the Merger Agreement with Philip Environmental Inc. (See "Subsequent
Event" below).
 
     In 1995, Schaffer secured an $83 million contract to engineer, design,
procure and construct a sugar factory and ethanol plant in Finchaa, Ethiopia. In
conjunction with the effectiveness of the contract, the Company received an
advance payment equal to 20.0 percent of the contract value. The project is
financed by the African Development Bank. Contractual payment amounts to
Schaffer are supported by a revolving letter of credit issued by the Ethiopian
government via the African Development Bank. The Company has issued letters of
credit to support performance and the 20.0 percent advance payment. At December
31, 1996, letters of credit of $6.3 million were outstanding to support the
unrecovered portion of the advance payment and $8.3 million to support project
performance guarantees.
 
     For the year ended December 31, 1996, net cash flows from continuing
operations were $7.9 million resulting primarily from depreciation and
amortization of $6.0 million, the $1.4 million charge, net decrease in accounts
receivable of $9.4 million, offset by a decrease in accounts payable and accrued
liabilities of $6.7 million. The decreases were due primarily to the lower level
of business activity during 1996. Net cash provided by investing activities
amounted to $0.2 million, resulting from $1.7 million in proceeds from sales of
property, plant and equipment and $0.8 million in investing activities related
to the discontinued EPC operations, partially offset by $2.0 million in capital
expenditures. Cash flows used in financing activities totaled $2.1 million
resulting from net principal payments of long-term debt and financing costs
incurred related to the November 1996 debt restructuring (see Note 5 of Notes to
Consolidated Financial Statements), and $0.7 million of debt payments related to
the discontinued EPC operations.
 
     Management believes that existing cash, cash flow from operations, and
existing credit facilities will be sufficient to meet the current ongoing
requirements of the operations of the Company. In addition, the above sources
may be supplemented with other external sources of funds to meet additional cash
requirements, if necessary.
 
IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS
 
     During 1996, the Company adopted Statement of Financial Accounting
Standards ("SFAS") No. 121 "Accounting for the Impairment of Long-Lived Assets
to be Disposed Of". This statement requires that long-lived assets and certain
identifiable intangible assets to be held and used by an entity be reviewed for
impairment whenever events or changes indicate the carrying amount of an asset
may not be recoverable. The adoption of SFAS No. 121 had no effect on the
consolidated financial statements for the year ended December 31, 1996.
 
     SFAS No. 123 "Accounting for Stock Based Compensation" was issued in
October 1995. SFAS No. 123 defines a fair value based method of accounting for
employee stock options. Under this fair value method, compensation cost is
measured at the grant date based on the fair value of the award and is
recognized over the service period; however, SFAS No. 123 allows an entity to
continue to measure compensation cost in accordance with Accounting Principal
Board Statement No. 25 ("APB 25"). The Company will continue to account for
stock option grants in accordance with APB 25, and recognizes no compensation
expense for stock options granted. Accordingly, the Company has adopted the
disclosure-only provisions of SFAS No. 123, see Note 10 of Notes to Consolidated
Financial Statements.

SUBSEQUENT EVENT
 
     On March 5, 1997, the Company entered into the Merger Agreement. Pursuant
to the Merger Agreement, Sub will be merged with and into the Company, and the
Company will become a wholly-owned subsidiary of Taro and an indirect,
wholly-owned subsidiary of Philip.
 
     Under the terms of the Merger Agreement, each share of Company Common Stock
will be exchanged for 0.403 share of Philip Common Stock (except for shares held
by persons who perfect and exercise dissenters' rights under Texas law),
provided that Philip will pay cash in lieu of any fractional shares of Philip
Common Stock to which holders of Company Common Stock would otherwise be
entitled. Based upon the closing price of Philip Common Stock on March 5, 1997,
each share of Company Common Stock is valued at $6.60 per share. In aggregate,
the transaction is valued at approximately $72.0 million, including the
assumption of approximately $21.0 million of Company indebtedness. The
transaction is subject to regulatory and shareholder approvals, and is expected
to close by June 30, 1997.
 
     Philip is a fully integrated, resource recovery and industrial services
company providing metals processing and mill services, solid and liquid
by-products recovery and industrial and remediation services to all major
industry sectors. Philip Common Stock trades on the New York Stock Exchange.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Basis of Presentation
 
     The consolidated financial statements include the accounts of Serv-Tech,
Inc., and its majority-owned subsidiaries. The Company's investments in
affiliated companies (50% and less owned) are accounted for in accordance with
the equity method. All significant intercompany balances and transactions are
eliminated.
 
  Revenues and Costs Recognition
 
     The Company engages in fixed price and modified fixed price contracts and
contracts based on costs incurred plus applicable profit percentages (time and
material contracts).
 
     Revenues from fixed price and modified fixed price contracts are recognized
on the percentage-of-completion method, measured primarily by the percentage of
costs incurred to date to estimated total costs for each contract (cost-to-cost
method). Management believes this method is the most appropriate measure of
progress on contracts. Revenues from time and material contracts are recognized
currently as costs are incurred in performing the work.
 
     Contract costs include all direct material and labor costs and those
indirect costs related to contract performance, such as indirect labor,
supplies, tools and repairs. Selling, general, and administrative costs are
charged to expense as incurred. Provisions for estimated losses on uncompleted
contracts are made in the period in which such losses are determined. Changes in
job performance, job conditions and estimated profitability may result in
revisions to costs and income which are recognized in the period in which the
revisions are determined.
 
     The asset, "Costs and estimated earnings in excess of billings on
uncompleted contracts," represents revenues recognized in excess of amounts
billed. The liability, "Billings in excess of costs and estimated earnings on
uncompleted contracts", represents billings in excess of revenues recognized.
 
  Research and Development Costs
 
     The Company expenses all research and development costs as they are named.
These costs, primarily related to Chemisolv's new paper-strengthening technology
Mastiff (SM), amounted to 0, $0.2 million and $0.9 million for 1994, 1995 and
1996, respectively.
 
  Cash and Cash Equivalents
 
     Cash and cash equivalents include cash, tax free municipal bond funds and
other highly liquid investments with maturities of three months or less at the
date of acquisition. Cash equivalents are stated at cost which approximates
market value.
 
  Inventory
 
     Inventory consists primarily of materials and supplies and is stated at the
lower of cost or market. Cost is determined principally by the average cost
method.
 
  Property, Plant and Equipment
 
     Property, plant and equipment are recorded at cost. Major renewals and
betterments which extend the lives of equipment are capitalized while all other
repairs and maintenance are charged to operations as incurred.
 
     Disposals are removed at cost less accumulated depreciation with any
resulting gain or loss reflected in results of operations.

                        SERV-TECH, INC. AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     For financial reporting purposes, depreciation for all property, plant and
equipment is provided using the straight-line method over the estimated useful
lives of the depreciable assets, ranging from three to 20 years.
 
     Accelerated methods are generally used for income tax purposes.
 
  Intangible Assets
 
     Intangible assets are carried at cost and amortized using the straight line
method over their legal or estimated useful lives. These lives range from 20 to
40 years for excess of costs over net assets of businesses acquired, 17 years
for patents and three to five years for covenants not to compete. The Company's
management assesses, at least quarterly, recorded balances of excess of costs
over net assets of businesses acquired net of accumulated amortization for
impairment in light of historic and projected operating trends and
profitability, new product development and strategic direction of the Company.
 
  Restricted Cash
 
     At December 31, 1996 and 1995, cash and cash equivalents include restricted
balances of $0.3 million and $0.6 million, respectively. The balances are
restricted for the guarantee of indebtedness of a subsidiary and for the payment
of claims, expenses and premiums under certain insurance policies. Any unused
balances are refundable to the Company.
 
  Foreign Currency Translation
 
     The assets and liabilities of the Company's foreign affiliates are
translated at year-end exchange rates, while income and expenses are translated
at average rates during the year. Translation adjustments are recorded as a
separate component of stockholders' equity.
 
  Income Taxes
 
     The Company recognizes deferred tax liabilities and assets for the expected
future tax consequences of events that have been included in the financial
statements or tax returns. Under this method, deferred tax liabilities and
assets are determined based on the difference between the financial statement
carrying amounts and tax basis of assets and liabilities using enacted tax rates
in effect in the years in which the differences are expected to reverse. The
Company does not provide deferred income taxes on undistributed earnings of
equity affiliates because such earnings are considered to be permanently
reinvested. The amount of deferred income taxes not provided is immaterial.
 
  Earnings (Loss) per Common Share of Stock
 
     Primary and fully diluted earnings (loss) per common share are based on the
weighted average number of shares outstanding during the year after
consideration of the dilutive effect of stock options reflected under the
treasury stock method. Fully diluted earnings per share are not presented
because such amounts would be similar to amounts computed for primary earnings
per share.
 
  Preferred Stock
 
     The Company can issue up to 2,000,000 shares of preferred stock with a par
value of $1.00 per share, none of which are issued or outstanding. The Company's
Board of Directors is authorized to divide the preferred stock into series and
to fix and determine the relative rights and preferences of each series.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Concentration of Credit Risk
 
     The Company provides specialized turnaround maintenance, electrical and
instrumentation, and environmental services, primarily to the hydrocarbon
(petroleum and natural gas related products) processing and production
industries principally in the United States. The Company performs ongoing credit
evaluations of its customers' financial condition. Although generally no
collateral is required from its customers, the Company may place liens against
the property constructed or serviced if payment default occurs. The Company
maintains reserves for potential losses and such losses have been within
management's expectations. See Note 3 regarding the Finchaa project. Excess cash
is invested principally in tax-free municipal bond funds consisting of
securities of municipalities with strong credit ratings. These investments
generally mature within three months and, therefore, bear minimal risk. The
Company has not experienced any losses on these type of short-term investments.
 
  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.
 
  Impact of Recently Issued Accounting Standards
 
     During 1996, the Company adopted Statement of Financial Accounting
Standards ("SFAS") No. 121 "Accounting for the Impairment of Long-Lived Assets
to be Disposed Of". This statement requires that long-lived assets and certain
identifiable intangible assets to be held and used by an entity be reviewed for
impairment whenever events or changes indicate the carrying amount of an asset
may not be recoverable. The adoption of SFAS No. 121 had no effect on the
consolidated financial statement for the year ended December 31, 1996.
 
     SFAS No. 123 "Accounting for Stock Based Compensation" was issued in
October 1995. SFAS No. 123 defines a fair value based method of accounting for
employee stock options. Under this fair value method, compensation cost is
measured at the grant date based on the fair value of the award and is
recognized over the service period; however, SFAS No. 123 allows an entity to
continue to measure compensation cost in accordance with Accounting Principal
Board Statement No. 25 ("APB 25"). The Company will continue to account for
stock option grants in accordance with APB 25, and recognizes no compensation
expense for stock options granted. Accordingly, the Company has adopted the
disclosure-only provisions of SFAS No. 123, see Note 10.
 
  Reclassifications
 
     Certain reclassifications have been made in order to conform to current
year presentation with no effect on net income (loss).

3. DISCONTINUED OPERATIONS
 
     In July 1996, the Company announced its intent to discontinue its
engineering, procurement and construction ("EPC") operations. The EPC operations
provided a full range of engineering consultation and project management
services primarily to the refining, petrochemical and food processing
industries. The discontinued EPC operations consisted of, (i) several domestic
EPC projects (which have now been completed), (ii) F.C. Schaffer and Associates
which includes the Finchaa Sugar Factory project as well as a consulting
engineering practice, (iii) a construction company in Orange, Texas (which has
been closed and substantially all remaining assets have been sold) and (iv)
engineering operations in Lake Charles and New Orleans, Louisiana (which have
been sold).
 
     The 1996 net loss from discontinued operations of $10.3 million (net of
income tax benefit of $4.4 million), or $1.54 per share, included a $9.7 million
($6.6 million, or $0.99 per share, on an after-tax basis) charge primarily for
the write-down of the profitability on several domestic EPC projects and the
Finchaa Sugar Factory project. The Finchaa project was written down to a $4.5
million loss ($2.9 million, or $0.43 per share, on an after-tax basis) during
the fourth quarter of 1996. Excluding the effects of this charge, the net loss
from discontinued operations was $3.7 million, or $0.55 per share for 1996
compared to net income of $2.8 million (net of income tax expense of $0.7
million), or $0.42 per share for 1995 and net income of $0.5 million (net of
income tax expense of $0.1 million), or $0.08 per share for 1994.
 
     Additionally, in conjunction with the decision to discontinue the EPC
operations, the Company recorded a $4.3 million (net of income tax benefit of
$1.0 million), or $0.64 per share, estimated loss on disposal of the EPC
operations for the estimated loss on sale and disposal of certain EPC divisions
and the related write-off of goodwill. The estimated loss on disposal of the EPC
operations includes $0.3 million, or $0.05 per share, estimated losses during
phase-out period.
 
     Net current assets from discontinued operations at December 31, 1996
consisted primarily of working capital associated with the Finchaa project and
the consulting engineering practice of F.C. Schaffer and Associates. Net
non-current assets from discontinued operations consisted primarily of property
and equipment, net of a note payable of $0.7 million.
 
     Revenues generated by the discontinued EPC operations for 1996, 1995 and
1994 were $70.3 million, $84.7 million and $13.3 million, respectively. 1996 and
1995 revenues included $38.9 million and $32.8 million related to the Finchaa
Sugar Factory Project, respectively.
 
  Finchaa Sugar Factory Project
 
     During the first quarter of 1995, F. C. Schaffer & Associates ("Schaffer"),
a subsidiary of the Company, secured an $83 million contract to engineer,
design, procure and construct a 4,000 metric ton cane-per-day sugar factory and
45,000 liter-per-day ethanol plant in Finchaa, Ethiopia. The project, which is
financed by the African Development Bank, is expected to be completed in the
latter part of 1997 followed by a twelve month warranty and training period. In
conjunction with the effectiveness of the contract, the Company received an
advance payment equal to 20% of the contract value. The Company has issued
letters of credit to support performance and the 20% advance payment. At
December 31, 1996, letters of credit of $6.3 million were outstanding to support
the unrecovered portion of the advance payment and $8.3 million to support
project

performance guarantees, see Note 5. Contractual payment amounts to Schaffer are
supported by a revolving letter of credit to be issued by the Ethiopian
government via the African Development Bank.
 
     As of December 31, 1996, the Finchaa project was approximately 80%
complete.
 
4. ACQUISITIONS
 
  ST Piping
 
     Effective May 18, 1995, the Company acquired an additional 20% of the
outstanding common stock of its specialty welding subsidiary, ST Piping, Inc.,
from the minority shareholders of that company. Consideration for the purchase
consisted of $0.6 million cash and 180,000 shares of Company common stock with a
fair market value of approximately $1.4 million (total consideration of $2.0
million). ST Piping, Inc. was formed in January, 1991, between the Company (70%
owner) and the Management Group of that company. This transaction now brings the
Company ownership to 90%. The purchase price and expenses associated with the
acquisition exceeded the fair value of net assets by approximately $1.2 million
and is included in intangible assets. The Company's consolidated financial
statements have included the results of operations of ST Piping, Inc. since
January 1, 1991. Pro forma results were not material to the Company's financial
position or results of operations.

     Effective June 14, 1994, the Company acquired all of the outstanding common
stock of Hartney Industrial Services Corporation ("Hartney"), a Houston, Texas,
company, in exchange for 450,000 shares of Company common stock with a fair
market value of $3.7 million. In addition, the Company paid $0.5 million in cash
for non-competition and confidentiality agreements entered into with the selling
shareholders. Pursuant to the terms of an earnout agreement, the Company may be
required to pay additional amounts based on Hartney's pre-tax earnings through
December 31, 1998. Amounts earned under the terms of the agreement will be
recorded as excess of costs over net assets of businesses acquired. The purchase
price and expenses associated with the acquisition exceeded the fair value of
net assets by approximately $3.0 million.
 
     Hartney is a specialty contractor which provides refractory, acid-proofing
and other corrosion prevention services to the petroleum refining,
petrochemical, cement, power generation and waste incineration industries.
 
  Chemisolv
 
     Effective November 8, 1994, the Company acquired the remaining 50% interest
in its affiliate Chemisolv Holdings, Inc. ("Chemisolv"), a specialty chemical
treatment company with operations in the United Kingdom and the United States.
The purchase price consisted primarily of 200,000 shares of Company common stock
with a fair market value of $1.4 million. In addition, the Company paid $0.5
million for non-competition and confidentiality agreements entered into with the
selling shareholders, consisting of $0.2 million cash and a $0.3 million note
payable due January, 1995. The purchase price and expenses associated with the
acquisition exceeded the fair value of net assets of the business acquired by
approximately $1.8 million.
 
     Unaudited pro forma combined results, assuming the Hartney and Chemisolv
acquisitions had occurred at January 1, 1994, are as follows:
 


                                                                 (IN THOUSANDS,

     The unaudited pro forma summary is not necessarily indicative either of
results of operations that would have occurred had the acquisitions been made at
the beginning of the periods presented, or of future results of operations of
the combined companies.
 
  SECO
 
     During 1994, the Company paid $800,000 to purchase all of the outstanding
redeemable preferred stock of SECO held by a former shareholder of that company.
Prior to July, 1994, annual cumulative dividends of $10 per share were paid
monthly and included in minority interest in the statement of operations.
 
     All acquisitions have been accounted for using the purchase method;
accordingly, the assets and liabilities have been recorded at their estimated
fair values at the date of acquisition. The excess purchase price and related
expenses over the fair value of net assets acquired is included in "excess of
costs over net assets of businesses acquired". Under the purchase method of
accounting, the results of operations are included in the consolidated financial
statements from their acquisition dates.
 
5. LONG-TERM DEBT
 
     In November 1996, the Company reached agreement with its lenders regarding
the restructuring of its debt facilities including the: (i) $15.0 million notes
held by four insurance companies (the "Notes"), (ii) revolving line of credit
with two banks (the "Revolver"), and (iii) the letters of credit supporting
performance and advance payment amounts related to the Finchaa Sugar Factory
project totaling $14.6 million at December 31, 1996.
 
     Effective November 12, 1996, under the new agreements, the Notes accrue
interest at a rate of 10.50% with 0.25% incremental increases each quarter
beginning January 1, 1998, through December 31, 1998 (rate caps at 11.50%
through maturity). The Notes are collateralized by substantially all assets of
the Company. Monthly principal payments of $208,333 are payable beginning July
1997, through the June 2003 maturity date.
 
     The Revolver permits borrowings up to $26.5 million until April 30, 1997,
when it decreases to $23.5 million, and further reduces to $19.5 million at June
30, 1997, until its scheduled December 31, 1997 maturity. Interest is payable
monthly at a rate equivalent to either eurodollar plus 4.09% (at December 31,
1996 the adjusted rate was 9.59%) or prime plus 1.0% (9.25% at December 31,
1996). Borrowings under the Revolver are collateralized by substantially all
assets of the Company. The Company pays a commitment fee of 0.25 percent on the
unused portion. At December 31, 1996, working capital borrowings of $5.6 million
were outstanding under the Revolver. Additionally, the Company has irrevocable
letters of credit totaling $4.6 million outstanding, to guarantee certain of the
Company's insurance programs and bid bonds, leaving total availability under the
Revolver, at $16.3 million. Borrowings under the Revolver are also subject to a
borrowing base computation, which is limited primarily to 75% of eligible
accounts receivable, as defined.
 
     The Notes, Revolver and Finchaa LOC agreements contain covenants, which
require, among others, that the Company maintain: (i) minimum consolidated net
worth, (ii) minimum cash flow (defined as earnings before interest, taxes,
depreciation and amortization), and (iii) minimum fixed charge coverage.
Additionally, the Company is limited in its debt-to-capitalization ratio as well
as capital expenditures. Draws, if any, under the Finchaa LOC would represent
loans, which would be secured by substantially all assets of the Company.
 
     As a result of the fourth quarter 1996 net loss, the Company was in
violation of various financial covenants. The Company received waivers from its
lenders with respect to such covenant violations as well as waivers necessary to
enter into the definitive merger agreement with Philip Environmental Inc. (See
Note 17).

     The aggregate maturities of long-term debt during the five years subsequent
to December 31, 1996, are approximately $1.6 million, $2.6 million, $2.5
million, $2.5 million, and $2.5 million, respectively.

     The Company recorded a valuation allowance for deferred tax assets in 1996
of $1,530,000. In assessing the realizability of deferred tax assets, management
considers whether it is more likely than not that some portion or all of the
deferred tax assets will not be realized. The ultimate realization of deferred
tax assets is dependent upon the generation of future taxable income during the
periods in which those temporary differences become deductible. Management
considers the scheduled reversal of deferred tax liabilities, projected future
taxable income, and tax planning strategies in making this assessment. In order
to fully realize all deferred tax assets, the Company will need to generate
future taxable income of approximately $8,600,000 prior to the expiration of the
net operating loss carryforwards in 2011. Based upon the level of historical
taxable income and projections for future taxable income over the periods which
the deferred tax assets are deductible, management believes it is more likely
than not the Company will realize the benefits of these deductible differences,
net of the existing valuation allowances at December 31, 1996. The amount of the
deferred tax asset considered realizable, however, could be reduced in the near
term if estimates of future taxable income during the carryforward period are
reduced.
 
7. RELATED PARTY TRANSACTION/TREASURY STOCK
 
     In August, 1995, Richard W. Krajicek retired as Chairman of the Company.
Mr. Krajicek was subsequently retained by the Company under a five year
consulting agreement. Mr. Krajicek, along with certain family members, owned
815,491 common shares of Company common stock. The Company has agreed to pay Mr.
Krajicek an amount equal to the shortfall, if any, between the average sales
price and $8.00 per share for up to 203,873 shares sold per year commencing on
November 9, 1995, and ending on November 9, 1999 (the "Krajicek Agreement"). The
average sales price, related to stock sold, shall be computed in arrears at the
end of each twelve month period and shall be based on the highest priced 203,873
shares (or portion thereof) sold during such period.
 
     On October 1, 1995, the Company purchased 203,873 shares of Serv-Tech stock
from Mr. Krajicek at the then fair market price of $8.00 per share, or a total
of $1.6 million, leaving 611,618 shares subject to the Krajicek Agreement.
 
     The Company recently reached an agreement with Mr. Krajicek to defer, to no
earlier than September 30, 1997 unless agreed by the Company, the cash
obligation that may be due, if any, during the period
 
                                       31

                        SERV-TECH, INC. AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
beginning November 9, 1996. Additionally, the cash obligation that may be due,
if any, during the period beginning November 9, 1997 has been deferred to no
earlier than February 1, 1998. Based upon the current level of the Serv-Tech
stock price ($5.375 per share as of March 14, 1997), Mr. Krajicek would be due
approximately $0.5 million (associated with the period beginning November 9,
1996), if the stock were sold pursuant to the terms of the Krajicek Agreement.
 
     See Note 8 for additional related party information regarding Mr. Krajicek.
 
8. STEWART & STEVENSON SETTLEMENT
 
     On July 25, 1996, the Company received a $30.0 million verdict by a
Houston, Texas jury on a retrial against Stewart & Stevenson Services, Inc.
("Stewart & Stevenson") for breach of an agreement that contained confidential
information and trade secrets. Before the trial, the parties entered into a
settlement agreement by which Stewart & Stevenson waived its right of appeal of
the trial-court judgment in the case and guaranteed a minimum recovery of
$250,000 in exchange for a $20.0 million cap on any recovery by the Company. In
September 1996, after payment of attorney's fees and a payment to the Company's
founder, Richard W. Krajicek, the Company received and recorded a $5.8 million
net settlement ($3.9 million on an after-tax basis, or $0.57 per share).
 
9. SPECIAL CHARGE
 
     During the third quarter of 1994, management performed a comprehensive
review of the Company's operating investment activities and structure. This
review was performed in light of management's new strategy for growth, which
focuses on operations that management believed would generate acceptable returns
on investments and elimination of activities that did not meet this criteria. As
a result of this review, the Company recorded a special charge of $12.2 million,
which consisted of non-cash write-offs including goodwill and other intangibles
($3.5 million), equipment ($1.6 million), and investment in affiliates ($1.2
million). Additionally, the special charge included certain project-related
reserves ($2.2 million) and accruals for employee-related and other costs ($3.7
million). The non-cash write-offs for goodwill and investments in affiliates
were primarily a result of management's decision to de-emphasize certain
domestic and foreign operations.
 
10. LONG-TERM INCENTIVE COMPENSATION, STOCK OPTIONS AND STOCK AWARD PLANS
 
     On May 18, 1995, the shareholders approved the 1995 Long-Term Incentive
Plan ("Plan") administered solely by the Long-Term Incentive Plan Committee of
the Board of Directors ("Committee"). The Plan permits the issuance of stock
options, stock appreciation rights ("SARs"), restricted stock awards,
performance grants and any other awards deemed consistent with the plan to key
employees of the Company and certain other key individuals, who perform services
for the Company. The Plan reserves 300,000 shares of Company common stock for
distribution. Under the terms of the Plan, options granted may be either
nonqualified or incentive stock options and the exercise price, determined by
the Committee, may not be less than 50 percent of the fair market value of the
underlying common shares at the time the option is granted; however, in the case
of incentive stock options issued to employees of the Company, the option price
may not be less than the fair market value of a share on the date of grant.
 
     The Committee may grant SARs either alone, or in conjunction with stock
options, performance grants or other awards. Upon exercise of such rights, the
optionee surrenders the exercisable portion of the option in exchange for
payment of the difference between the aggregate option price and the aggregate
fair market value on the date of surrender. Payment may be in the form of cash
and/or common stock valued at its fair market value on the date of surrender.
SARs utilize the same shares reserved for issuance of options, and the exercise
of a SAR or option automatically cancels the related option or SAR. SARs become
exercisable and expire on the same dates as the related options. There were no
SARs issued during 1996.

     Restricted stock awards are issuances of a given number of shares of
Company common stock that are restricted as to the sale and transfer of the
shares; participants are entitled to all rights of a shareholder. Restricted
stock awards vest 20 percent on the date of grant with the remaining shares
vesting within four years. The cost of the awards are charged to expense over
the vesting period. During 1996, 64,800 restricted stock awards were granted
under the Plan. Compensation expense associated with the vesting of stock awards
was $0.1 million in 1996.
 
     Performance grants entitle a participant to receive specified awards, as
determined by the Committee, if certain performance objectives are achieved
during a specified period. There were no performance grants awarded under the
plan during 1996.
 
     Prior to the Plan, the Company had two Incentive Stock Option Plans ("ISO
Plans") that provided up to 920,000 shares of common stock to selected officers
and key employees of the Company. Subject to various conditions, the outstanding
options are exercisable for up to ten years at an option price not less than
market price on the date the option is granted. In connection with the
establishment of the Plan, the ISO Plans were amended to prohibit the grant of
additional common stock options, thereby canceling the remaining shares of
Company stock available for future awards, except for any options which become
available by way of forfeiture of any presently outstanding options.
 
     The Company maintains a Director Stock Option Plan that provides up to
50,000 shares of common stock for issuance to certain non-employee directors of
the Company. The stock options are exercisable for up to ten years, at an option
price not less than the market price on the date the option is granted. The
Company has nonqualified stock options, not granted pursuant to a shareholder
approved plan, with certain key officers, directors, employees and consultants
of the Company. The Agreements provide for the issuance of 378,000 shares of
Company common stock at exercise prices ranging from $3.00 -- $7.75 and are
exercisable, subject to various conditions, for various terms of up to ten
years.
 
     The following table sets forth pertinent information regarding stock option

731,900 have an option price of $3.00 per share. The remaining 375,500 stock
options outstanding have option prices ranging from $5.625 to $9.125 per share.
 
     The Company had 461,800, 503,050, and 280,250, shares of Common Stock
available for grant under existing stock option plans at December 31, 1996,
1995, and 1994, respectively.
 
     As discussed in Note 1, the Company has elected to continue to measure
compensation cost related stock options in accordance with APB 25. However, if
compensation costs were measured using the fair value of the stock options on
the date of grant, during 1995 and 1996, in accordance with SFAS No. 123, the
Company's net earnings (loss) would be as follows:

     The weighted average fair value of options granted in 1995 and 1996 were
$3.74 and $2.11, respectively. The fair value of each option was determined
using the Black-Scholes option valuation model with the following assumptions
(i) risk free interest rate of 6.46 percent, (ii) expected volatility of 49.27
percent, and (iii) expected option life of 6 years and (iv) no annualized
dividend yield.
 
11. COMMITMENTS AND CONTINGENCIES
 
     The Company is involved in various claims and disputes incidental to its
business. The Company believes that the disposition of all such claims and
disputes, individually or in the aggregate, should not have a material adverse
effect upon the Company's financial position, results of operations or cash
flows.
 
     At December 31, 1996, the Company had irrevocable letters of credit
outstanding of approximately $19.8 million. The letters of credit were issued
primarily to (i) guarantee certain of the Company's insurance programs amounting
to $4.6 million, (ii) support Finchaa Sugar Factory Project procurement
amounting to $0.6 million, (iii) $6.3 million to support the unrecovered portion
of the Finchaa project advance payment and (iv) to support job performance
guarantees on the Finchaa project amounting to $8.3 million.
 
  Operating Lease Commitments
 
     The Company has entered into operating leases for various types of
equipment and for its building facilities. Most leases contain purchase and
renewal options at fair market and rental values. Rental expense was
approximately $2.5 million, $2.3 million, and $2.2 million for the years ended
December 31, 1996, 1995, and 1994, respectively.
 
     The following is a schedule of minimum rental commitments under
noncancelable operating leases. Minimum lease payments have not been reduced by
minimum sublease rentals of $2,258,000 due in the future.

INSURANCE
 
     The Company maintains a comprehensive property and casualty risk management
program including worker's compensation insurance for its employees and other
coverages for normal business risks. In many cases, the Company is responsible
for the payment of incurred claims up to specified individual and aggregate
limits, over which a third party insurer is contractually liable for any
additional payment of such claims. Accordingly, the Company bears certain
economic risks related to these coverages. The Company records an accrual equal
to the estimated costs expected to result from incurred claims plus an estimate
of claims incurred but not reported based on the best available information.
However, the nature of these claims is such that actual development of the
claims may vary significantly from the estimated accruals. All changes in the
accrual estimates are accounted for on a prospective basis and could have a
significant impact on the Company's financial position or results of operations.
 
12. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The carrying values of cash and cash equivalents, accounts receivable and
payable, accrued liabilities and the Revolving Note are considered to
approximate fair value due to the short-term nature of these instruments. The
carrying value of long-term debt is estimated to approximate fair value based on
the Company's current incremental borrowing rates for similar types of borrowing
arrangements.
 
     In the normal course of business, the Company issues letters of credits and
other guarantees which are not reflected in the consolidated balance sheet. In
the past no significant claims have been made against these financial
instruments and management expects no material losses to occur.
 
13. SUPPLEMENTAL CASH FLOW INFORMATION
 
     Cash paid during the three years ended December 31, 1996, for interest and
income taxes was as follows:
 


                                                    1996          1995          1994

14. DEFINED CONTRIBUTION PLANS
 
     The Company maintains a defined contribution 401(k) plan for its permanent
employees. Under the plan, eligible employees may contribute amounts through
payroll deductions for investment in various funds established by the plan. The
Company matches 50% of a participant's voluntary contribution up to a maximum of
6% of a participant's compensation in Company common stock. The costs of the
plan were $0.7 million, $0.7 million, and $0.6 million in 1996, 1995, and 1994,
respectively. The Company recently amended its 401(k) plan, effective, April 1,
1997, to replace the Company matching contribution with a discretionary profit
sharing contribution determined by the Company's Board of Directors on an annual
basis (in arrears).
 
15. BUSINESS SEGMENT AND MAJOR CUSTOMERS
 
     The Company's operations include three primary business segments: (i)
Specialty Services, (ii) SECO Industries ("SECO") and (iii) Environmental and
Performance Chemicals ("Environmental"). Specialty Services provides specialized
turnaround maintenance, welding, boiler repair and refractory services primarily
to the refining, petrochemical, power, paper and cement industries. SECO
installs electrical and instrumentation systems for offshore production
platforms, refineries, petrochemical processing plants and food processing
plants. Environmental includes tank cleaning, decontamination services and the
Company's specialty chemical company, Chemisolv. The operations and assets of
Chemisolv have been included from the date of acquisition, November 1994 (See
Note 4).
 
     Operating profit (loss) is defined as total revenue less direct and
operating expenses. Identifiable assets are those assets directly identifiable
with operations in each segment. Corporate and Other consist primarily of cash
and cash equivalents, certain receivables and the corporate facilities.

                          INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors and Stockholders of Serv-Tech, Inc.:
 
     We have audited the accompanying consolidated balance sheets of Serv-Tech,
Inc. and Subsidiaries as of December 31, 1996 and 1995, and the related
consolidated statements of operations, changes in stockholders' equity, and cash
flows for the years then ended. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits. The
accompanying consolidated statements of operations, changes in stockholders'
equity and cash flows of Serv-Tech, Inc. and Subsidiaries, for the year ended
December 31, 1994, were audited by other auditors whose report thereon dated
February 17, 1995, expressed an unqualified opinion on those statements.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the 1996 and 1995 consolidated financial statements
referred to above present fairly, in all material respects, the financial
position of Serv-Tech, Inc. and Subsidiaries at December 31, 1996 and 1995, and
the results of their operations and their cash flows for the years then ended in
conformity with generally accepted accounting principles.

    (iv) options exercised 10 years from the date of grant, and (v) a discount
    rate of 3% per year during the 3 year vesting period to reflect the risk of
    forfeiture of unvested stock options. These assumptions were based upon 6
    years of historical monthly trading data.

                 SERV-TECH, INC. COMPENSATION COMMITTEE REPORT
                           ON EXECUTIVE COMPENSATION
 
     In fiscal year 1996, the Compensation Committee (the "Committee") was
comprised of 3 non-salaried directors, Messrs. O'Brien (Chairman) Hock and
Piette, who also comprise the Administrative Committee of the Company's Long
Term Incentive Plan. For the remainder of this report, the Administrative
Committee is considered a part of the Compensation Committee except as otherwise
indicated.
 
     The Compensation Committee makes recommendations to the Board regarding
executive officer salaries and bonuses, and the Administrative Committee of the
Long Term Incentive Plan makes decisions regarding stock option grants and stock
awards. All recommendations of the Compensation Committee are reviewed and
approved by the entire Board of Directors (except that directors who are also
executive officers or serve as Chairman of the Board abstain from voting with
respect to their own compensation) except as otherwise indicated.

COMPENSATION POLICY
 
     The compensation policy of the Company, which is endorsed by the Committee,
is that a substantial portion of the annual compensation for each executive
officer should relate to and be dependent upon the performance of the Company as
well as the individual contribution of each officer. Consequently, the
compensation program is designed to motivate senior management and to align the
interests of executive officers with the long-term interest of shareholders.
 
COMPENSATION PROGRAM COMPONENTS
 
     The executive compensation program is comprised of salary, annual cash
bonus awards and long-term incentive opportunities primarily in the form of
stock options.
 
     Base Salary -- At senior executive levels, base salaries are modest by
industry standards. Actual salaries are based on individual performance,
comparative levels of responsibility and competitive marketplace relationships.
 
     Annual Bonus Awards -- Except for bonus amounts awarded on the basis of
exceptional and meritorious achievement, the Company awards annual bonuses based
on the attainment of certain operating objectives. Executive officer bonuses are
derived from a specific quantitative formula approved by the Compensation
Committee based on ultimate financial performance of the Company and its
operating subsidiaries as measured against Board approved financial goals.
 
     Stock Option Plans -- The Committee strongly believes that it is in the
best interest of the shareholders for the Company compensation to be tied
directly to shareholder return by the participation of key executives in
long-term incentive stock awards. Therefore, key executives and management are
eligible to receive, from time to time, stock options which give them the right
to purchase stock in the future at a specified price. The number of stock
options granted to executive officers is based on individual performance,
performance of the Company's subsidiaries and competitive practices. In view of
the decline in price of the Company's stock price in 1996 and the need to
maintain an incentive for Company management, the Committee approved the
exchange of all outstanding stock options held by current directors and active
employees for new stock options with a $3.00 per share exercise price and a new
3 year vesting period. Except with respect to non-employee directors and except
with respect to 25,000 share options to the Chairman, Mr. Cresci, all stock
options issued pursuant to the October 1, 1996, exchange have a new 3 year
vesting schedule regardless of the majority-vested status of the stock options
so exchanged.
 
COMPENSATION OF THE CHIEF EXECUTIVE OFFICER
 
     As Chairman of the Board, Mr. Cresci's retainer is determined by the
members of the Compensation Committee based on the performance of the Company
and the efforts of Mr. Cresci. The Board raised Mr. Cresci's annual retainer
from $75,000 to $100,000 effective May 23, 1996, to reflect Mr. Cresci's
additional duties as President and Chief Executive Officer of the Company
commencing as of that date.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
     As disclosed in Note 17 of Notes to the Consolidated Financial Statements
in Item 8 above, the Company recently entered into an Agreement and Plan of
Merger with Philip Environmental, Inc. (the "Merger"). Upon consummation of the
Merger, the Company will pay to Mr. Robert J. Cresci, Chairman, President and
Chief Executive Officer an amount equal to $150,000. In addition, upon
consummation of the Merger, the Company will pay transaction bonuses to David P.
Tusa, Senior Vice President, Finance and Administration, Frank A. Perrone, Vice
President, General Counsel and Corporate Secretary, and Dale W. Wilhelm,
Corporate Controller, in the amounts of $140,000, $50,000, and $45,000,
respectively.
 
     The Employment Agreement of Mr. Tusa dated as of August 29, 1994, as
amended, and the Employment Agreement of Mr. Perrone dated as of November 10,
1994, as amended, (collectively, the "Employment Agreements"), each provide for
the payment of certain benefits to Mr. Tusa and Mr. Perrone
 
                                       49
   52
 
(each being referred to as the "Executive") upon termination of their employment
within three years after a Change in Control (as defined in the Agreements). The
Merger will constitute a "Change in Control" under the Agreements. Accordingly,
if within three years after the consummation of the Merger, either (i) the
Company terminates the Executive's employment for any reason (other than the
Executive's retirement, disability or death) or (ii) the Executive resigns from
his employment with the Company for any reason, then the Executive will be
entitled to receive the following benefits from the Company:
 
          (i) a cash payment equal to (a) the Executive's base salary (plus car
     allowance) for either the 18 month period ending immediately before
     consummation of the Merger or the 18 month period ending immediately before
     the termination of the Executive's employment, whichever is greater, minus
     (b) the minimum amount required to avoid certain adverse excise tax and
     federal income tax consequences to the Executive and the Company,
     respectively, resulting from "excess parachute payments";
 
          (ii) medical and life insurance coverage, paid by the Company, as in
     effect immediately before the Merger for a period of 18 months after the
     Executive's termination, unless the Executive becomes eligible for such
     coverage from a subsequent employer; and
 
          (iii) 18 months of additional service credit for all purposes,
     including vesting, retirement, eligibility, and benefit accrual, under all
     employee benefit plans sponsored by the Company in which the Executive
     participated immediately before the Merger.
 
     The Company has agreed to provide certain supplemental benefits to Mr.
Wilhelm. Specifically, if Mr. Wilhelm's employment is terminated either by the
Company, without cause or by resignation of Mr. Wilhelm prior to reaching the
age of 64 1/2, the Company will pay Mr. Wilhelm a lump sum severance payment
equal to 12 months of his salary (plus car allowance) at the time of such
termination or resignation. In addition, Mr. Wilhelm will be entitled to retain
certain benefits (group health, dental and car allowance) on the then current
terms and cost for the 12 months subsequent to such termination or resignation,
unless Mr. Wilhelm becomes eligible for such benefits from a subsequent
employer.
