       PART I
 
Item 1.  Business

Background

Matrix Service Company (the "Company") provides specialized on-site
maintenance and construction services for petroleum  refining and storage
facilities and water storage tanks and systems for the municipal and
private industry sector.  Owners of these facilities use the Company's
services in an effort to improve operating efficiencies and to comply with
stringent environmental and safety regulations.  Through its subsidiaries
Matrix Service, Inc.("Matrix"), San Luis Tank Piping Construction Co., Inc.,
and an affiliated company West Coast Industrial Coatings, Inc. (collectively
"San Luis"), Heath Engineering, Ltd., and an affiliated company ("Heath"),
Brown Steel Contractors, Inc. and affiliated companies (collectively, "Brown")
and Mayflower Vapor Seal Corporation ("Mayflower"), the Company provides
maintenance and construction services and related products for large
aboveground storage tanks ("ASTs") holding petroleum, petrochemical and
other products and piping systems located at petroleum refineries and bulk
storage terminals.  Also, the Company provides field-erected, elevated and
ground-level water tanks for the municipal and private industry sector.
Through its subsidiaries, Midwest Industrial Contractors, Inc. ("Midwest"),
and Colt Construction Company ("Colt"), the Company provides maintenance and
construction services for refineries.  Midwest and Colt specialize in
performing "turnarounds", which involve complex, time-sensitive maintenance
of the critical operating units of a refinery.  The Company focuses on
fluid catalytic cracking units and process heaters, but has the ability to
work on all units within a refinery.

The Company was incorporated in Delaware in 1989 to become a holding company
for Matrix, which was incorporated in Oklahoma in 1984, and Petrotank
Equipment Inc. ("Petrotank"), which was incorporated in Oklahoma in 1988.
In October 1990, the Company acquired through a subsidiary substantially all
of the assets and operations of Midwest.  In June 1991, the Company acquired
San Luis (the "San Luis Acquisition").  In December 1992, the Company acquired
through a subsidiary substantially all of the assets and operations of Colt.
In June 1993, the Company acquired substantially all of the assets and assumed
certain liabilities of Heath. In July 1993, the Company entered into a joint
venture (Al Shafai-Midwest Constructors) with a Saudi Arabian company to
perform mechanical contracting services in the Kingdom of Saudi Arabia.
Al Shafai-Midwest Constructors is 49%  owned by Midwest International, Inc.,
a wholly-owned subsidiary of the Company.  Al Shafai-Midwest Constructors was
issued a commercial license to perform services in Saudi Arabia in June 1993.
In May 1995, the Company discontinued operations in Saudi Arabia, and is in
the process of liquidating the joint venture.  In April 1994, the Company
acquired Brown.  In August 1994 the Company acquired certain assets of
Mayflower Vapor Seal Corporation. Unless the context otherwise requires,
all references herein to the Company include Matrix Service Company and its
subsidiaries.  The Company's principal executive offices are located at
10701 East Ute Street, Tulsa, Oklahoma  74116, and its telephone number at
such address is (918) 838-8822.

Recent Development - The MainServ Acquisition

On June 17, 1997, the Company acquired (the "MainServ Acquisition") General
Service Corporation and affiliated companies (collectively, "MainServ"). 
MainServ provides services and products similar to those provided by Matrix
and operates primarily in the Northeast part of the United States, with
products sales to U.S. and foreign customers.  The aggregate consideration
payable for the MainServ Acquisition is up to$7.75 million, including
certain potential future payments.  A portion of the consideration was
payable by delivery at the closing of the transaction of (i) $4.75 million
in cash, and (ii) a $250,000 promissory notes payable in 12 equal quarterly
installments.  In addition, the stockholders and stock appreciation rights
holders of MainServ are entitled to receive in the future up to an additional
$2.75 million in cash if MainServ satisfies certain earnings requirements.
The MainServ Acquisition will be accounted for under the "Purchase" method
of accounting and will result in the creation of approximately $2.9 million
of intangibles (excluding goodwill that would be attributable to the $2.75
million contingent earnout payment if it is paid), of which $2.3 million,
representing the goodwill, will be amortized by the Company over a 40-year
period and $600 thousand, attributable to noncompetition covenants, will be
amortized over a three-year period.  See the Notes to the Company's
consolidated financial statements included elsewhere in this annual report.
  
Aboveground Storage Tank Operations

The Company's AST operations include the maintenance, repair, inspection,
design and construction of ASTs, and the equipping of these tanks with
devices mandated by current and proposed environmental regulations.  These
devices include a variety of floating roof and seal assemblies, tank bottoms
and secondary containment systems, each of which is designed to enable tank
owners and operators to comply with federal and state air and water quality
guidelines and regulations regarding leaks and spills of petroleum products
from storage facilities.The Company manufactures and sells certain of these
devices, including a line of patented floating roof seals.  These seals,
which are marketed under the Company's Flex-A-Seal and Flex-A-Span trademarks,
reduce losses of stored petroleum products through evaporation and,
consequently, reduce air pollution.  In addition, the seals reduce the amount
of rainwater that enters the tanks, reduce the hazards of rim fires thereby
reducing product contamination, lowering waste-water disposal costs, and
reduce tank owner's overall risk.  The Company's secondary containment
systems allow tank owners to detect leaks in the tanks at an early stage,
before groundwater or surface water contamination has occurred.  In addition,
the systems help to control leakage until the tank can be repaired.

AST Market and Regulatory Background

The American Petroleum Institute has estimated that there are approximately
700,000 ASTs in the United States that store crude oil, condensate, lube
oils, distillates, gasolines and various other petroleum products.  These
tanks range in capacity from 26 barrels (42 gal/barrel) to in excess of
1,000,000 barrels.  The Company's principal focus is inspecting,
maintaining, repairing, designing and constructing large ASTs, with
capacities ranging from approximately 50 to 1,000,000 barrels.  The Company
believes, based on industry statistics, that there are over 120,000 of
these large tanks currently in use, accounting for more than 70% of the
domestic petroleum product storage capacity.  These ASTs are employed
primarily by the refining and storage segments of the petroleum industry. 
The petrochemical industry also employs a significant number of large ASTs.

Historically, many AST owners limited capital expenditures on ASTs to new
construction and periodic maintenance on an as-needed basis.  Typically,
these expenditures decreased during periods of depressed conditions in the
petroleum and petrochemical industries, as AST owners sought to defer
expenditures not immediately required for continued operations.

In the two most recent years, there has been some increased demand for AST
services; however, during fiscal years 1995 and 1994 there was a decrease
in the overall demand for AST services, generally related to conditions in
the petroleum industry.  During the last three years, several factors have
shifted new responsibilities to AST service companies.   First, increased
safety and health requirements have caused owners of the facilities to rely
on outside sources who have the safety equipment and training to provide
repair and maintenance services. Second, increasingly stringent federal and
state regulations regarding air, soil and water contamination from petroleum
storage facilities, and the related potential liability associated with
responsibility for environmental damage, have led AST owners to rely on
service companies to provide more preventive maintenance and equip their
ASTs with various pollution control devices.  Third, many technical personnel
left the petroleum and petrochemical industries resulting in a loss of in-house
AST management expertise.  Fourth, recent changes in the marketing of gasoline
and changes in the supply of refined petroleum products resulting from the
closing of certain refineries have caused an increase in demand for new
tankage to provide storage facilities at new locations.  Fifth, environmental
requirements for oxygenated fuels has also created a demand for new tanks.

The principal environmental regulations that affect AST owners generally
fall within two categories - air pollution regulations and soil and water
contamination regulations.  See "Business - Other Business Matters -
Regulation."  Regulations adopted by the United States Environmental
Protection Agency ("EPA") and several states provide incentives to owners
and operators of ASTs to maintain and inspect their tanks on a regular
basis and, in some cases, to install double tank bottoms and other
secondary containment systems to prevent contamination of soil and water
and allow for early detection of leaks.  The EPA and numerous states have
also adopted regulations generally requiring facilities that hold petroleum
products, petrochemicals and other volatile liquids be equipped with roof
and seal assemblies that substantially decrease atmospheric emissions from
these liquids.  Because many existing ASTs were designed with a floating
roof assembly that contained only a single roof seal, these regulations
have required many AST owners to retrofit their tanks with new roof and
seal assemblies.  See "Aboveground Storage Tank Operations - AST Services
and Products" and "Other Business Matters - Regulation."


On March 29, 1990, the EPA published the Toxicity Characteristic Leachate
Procedure (the "TCLP") regulation, which provided new guidelines for
identifying certain wastes as "hazardous" under the Resource Conservation
Recovery Act of 1976 ("RCRA").  The TCLP regulation continues to be
amended.  The regulation generally provides that a waste will be considered
hazardous if the leachate from the TCLP leaching procedure test contains
any one of several identified substances at concentrations higher than
prescribed levels.  These  substances include benzene, a common component
of petroleum wastes from refineries.  Benzene was not included in the prior
EPA leaching procedure test, which has been replaced by the TCLP.  The
Company believes that regulations pursuant to the TCLP and RCRA have been,
and will continue to be, beneficial to its business by requiring its
customers to construct new storage tanks to replace existing surface
impoundments.  See "Other Business Matters - Regulation."

In January 1991, the American Petroleum Institute ("API") adopted industry
standards for the maintenance, inspection and repair of existing ASTs.  The
API standards provide the industry for the first time with uniform guidelines
for the maintenance and repair of ASTs.  The Company believes that these
standards have resulted, and will continue to result, in an increased
level of AST maintenance and repair on the part of many AST owners.

AST Services and Products

The Company provides its customers with a comprehensive range of AST
services and products.  The Company specializes in maintenance and repair
of ASTs and retro-fitting existing ASTs with a variety of pollution control
devices as part of its general maintenance services.  In addition, the
Company constructs new ASTs, provides AST inspection and manufactures tank
appurtenances. 

New Construction

The Company designs, fabricates and constructs new ASTs to both petroleum
and water industry standards and customer specifications.  These tanks
range in capacity from approximately 50 barrels to 1,000,000 barrels. 
Clients require new tanks in conjunction with expansion plans, replacement
of old or damaged tanks, storage for additional product lines to meet
environmental requirements, replacement of surface impoundments and changes
in population.

Maintenance and Modification
        
The Company derives a significant portion of its revenues from providing
AST maintenance, repair and modification services.  The principal services
in this area involve the design, construction and installation of floating
roof and seal assemblies, the design and construction of secondary
containment systems (double bottoms), and the provision of a variety of
services for underground and aboveground piping systems.  The Company also
installs, maintains and modifies tank appurtenances, including spiral
stairways, platforms, water drain-off assemblies, roof drains, gauging
systems, fire protection systems, rolling ladders and structural supports.

Floating Roof and Seal Assemblies.  Many ASTs are equipped with a floating
roof and seal assembly.  A floating roof consists of a circular piece of
welded steel or thin aluminum that floats on the surface of the stored
petroleum product.  The floating roof is required by environmental
regulations to minimize vapor emissions and reduce fire hazard.  A floating
roof also prevents losses of stored petroleum products.  The seal spans the
gap between the rim of the floating roof and the tank wall.  The seal
prevents vapor emissions from an AST by creating the tightest possible seal
around the perimeter of the roof while still allowing movement of the roof
and seal downward and upward with the level of stored product.  In
addition, the Company's seal system prevents substantially all rain water
from entering the tank.  The type of seal assembly the Company most
commonly installs consists of a primary mechanical "shoe" seal and a
secondary flexible seal mounted above the shoe seal.  A mechanical shoe
seal is a metal sheet connected to the outer rim of a floating roof and
held vertically against the wall of the storage vessel by hangers and
springs system.  A flexible coated "vapor" fabric spans the space between
the metal shoe and the floating roof.  The secondary seal is composed of a
flexible tip and an additional vapor fabric mounted on a metallic
compression plate attached to the  rim of the floating roof.  The Company's
seals are manufactured from a variety of materials designed for
compatibility with specific petroleum products.  All of the seals installed
by the Company may be installed while the tank is in service, which reduces
tank owners' maintenance, cleaning and disposal costs.  In addition to a
mechanical shoe seal coupled with a secondary flexible seal, the Company
also installs a variety of other types of seal systems designed to meet
customer specifications.

Secondary Containment Systems.  The Company constructs a variety of
secondary containment systems under or around ASTs according to its own
design or the design provided by its customers.  Secondary leak detection
systems allow tank owners to detect leaks in the tanks at an early stage
before groundwater contamination has occurred.  In addition, the systems
help to contain leakage until the tank can be repaired.

The most common type of secondary containment system constructed involves
installing a liner of high-density polyethylene, reinforced polyurethane
or a layer of impervious clay under the steel tank bottom.  The space
between the liner and elevation of the new bottom is then filled with
a layer of concrete or sand.  A cathodic protection system may be installed
between the liner and the new bottom to help control corrosion.  Leak
detection ports are  installed between the liner and steel bottom to
allow for visual inspection while the tank is in service.

The Company believes that during the 1990's a substantial number of AST
owners have installed, and will continue to install, secondary containment
systems. 

Elevated Tanks                    

In April 1994, as a result of the Company's efforts to expand its product
base, the Company purchased Brown Steel, which designs, fabricates and
erects elevated tanks for water storage for municipalities and industrial
customers.  Brown's facilities in Georgia include fabrication equipment,
and buildings containing 184,350 square feet support the elevated tank
operations.  The equipment gives Brown the ability to produce two-dimension
roll in steel for the fabrication of spherical shaped tanks.  This facility
is qualified to perform services on equipment that requires American Society
of Mechanical Engineering Code Stamps ("ASME Codes"). Demand for these types
of tanks is expected to increase given the current upturn in housing starts
resulting in a corresponding increase in the demand for water.          
    
                                                       

Manufacturing
                 
 The Company owns and operates a "state-of-the-art" fabrication facility
located on 13 acres at the Tulsa Port of Catoosa.  The Company owns the
building and equipment.  This facility has the capacity to fabricate new
tanks, new tank components and all maintenance, retrofit and repair parts
including fixed roofs, floating roofs,  seal assemblies, shell plate and
tank appurtenances.  The Tulsa Port has transportation service via railroad
and Mississippi River barge facilities in addition to the interstate highway
system, making it economical to transport heavy loads of raw material and
fabricated steel.  This facility is qualified to perform services on
equipment that requires ASME Codes.  Many state agencies and insurance
carriers require that certain equipment be ASME coded.  Many of the
Company's competitors are not ASME code qualified, forcing them to
subcontract portions of a project, giving the Company an advantage on this
type of work.

The Company leases two manufacturing facilities in California and owns a
manufacturing facility in Georgia.  See "Business - Aboveground Storage
Tank Operations - Elevated Tanks" for a description of the facility in
Georgia.  The Company rents the real estate and owns the equipment in the
two leased facilities in California which is used for fabricating new tanks
and tank components.

Hydrocarbon Process Operations

The Company provides specialized maintenance and construction services to
the domestic petroleum refining industry and, to a lesser extent, to the
gas processing and petrochemical industries.  The Company specializes in
routine and supplemental plant maintenance, turnarounds and capital
construction services, which involve complex, time-sensitive maintenance of
the critical operating units of a refinery.  The Company concentrates on
performing these services for the more structurally complex components in a
refinery.  See "Hydrocarbon Process Operations - Hydrocarbon Process
Components".

Hydrocarbon Process Market Overview

The domestic petroleum refining industry presently consists of approximately
163 operating refineries.  To ensure the operability, environmental compliance,
efficiency and safety of their plants, refiners must maintain, repair or
replace process equipment, operating machinery and piping systems on a
regular basis.  Major maintenance and capital projects require the shutdown
of an operating unit, or in some cases, the entire refinery.  In addition to
routine maintenance, numerous repair and capital improvement projects are
undertaken during a turnaround.  Depending on the type, utilization rate,
and operating efficiency of a refinery, turnarounds of a refinery unit
typically occur at scheduled intervals ranging from six months to four years.

The U.S. refinery industry has undergone significant changes in the last 16
years.  From 1981 to 1997, crude oil refining capacity dropped from a peak
of approximately 18.6 million barrels per day in 1981, to approximately
15.3 million barrels per day by the end of 1996, due primarily to the
closure of many inefficient refineries.  The closings were the result of
increased international competition, reduced demand for domestic petroleum
products, which resulted in declining product prices during the first part
of this period, and the inability of some refineries to cost effectively
finance capital improvements required to produce cleaner burning fuels and
meet environmental regulations.

Since 1993, a combination of increased demand for petroleum products and a
stabilization in refining capacity has led to a substantial increase in
refinery utilization.  In addition,  an improvement in refining profitability
during the last two years has also provided an incentive for refiners to
maintain high levels of utilization at their facilities.  The high utilization
rates have accelerated the physical deterioration of existing refineries,
intensifying the need for repair and maintenance services.  In addition, due
to the high cost and environmental opposition associated with the construction
of new refineries, any increase in current refining capacity is likely to
involve refurbishing old refineries and expanding existing facilities, which
will require specialized construction services.  Increased utilization rates
and increased refining profitability provide an incentive for refineries to
minimize the duration of maintenance turnarounds.  In addition, increased
public awareness of environmental issues, potential liability for exposure to
hazardous working conditions, toxic materials, and environmental contamination,
have resulted in increased stringent regulations which dictate that refineries
clean, inspect and maintain process and storage facilities more frequently.
Further, refineries have been subject to increasing regulatory pressure to
upgrade their emission control systems.

These factors have encouraged refineries to increase their reliance on
outside contractors who can perform specialized turnaround services within
strict time constraints.  The Company believes, for example, that
substantially all fluid catalytic cracking unit turnarounds are currently
performed by outside contractors.  Additional specialized modifications to
many existing refineries may be required to produce cleaner burning,
reformulated gasolines and desulphurized diesel fuel based on amendments to
the Clean Air Act.  See "Other Business Matters - Regulation."  Management
believes that projects related to pollution control are contributing a
significant part of the Company's refinery-related revenues.

Hydrocarbon Process Components

The Company's principal refinery services are related to turnaround projects
at petroleum refineries.  The size and complexity of a turnaround project
depends on the type of refinery unit being maintained or modified and the
nature of any necessary modifications.  The following paragraphs describe
the major units involved in a typical refinery.  The Company performs
turnaround services with respect to each of the units described below, all
of which must be maintained on a regular basis to ensure safe and efficient
refinery operations.

Crude Distillation Unit.  In the refining process, hydrocarbon raw materials
(primarily crude oil) are heated to approximately 275 degrees Farenheit.
The crude is then treated to remove salt and then heated further, resulting
in partial vaporization.  The vapors are then routed to a crude distillation
unit, where they are further heated.  The hydrocarbon compounds that comprise
crude oil separate, or "fractionate", when subjected to high temperatures.
The crude distillation unit fractionates the hydrocarbons into several
intermediate products, several of which undergo further processing in various
downstream units, the most important of which are discussed below.

Fluid Catalytic Cracking Unit.  Catalytic cracking greatly enhances the
efficiency of a refinery by converting a greater percentage of hydrocarbon
compounds to gasoline and other light distillates.  The Fluid Catalytic
Cracking Unit ("FCCU") mixes straight-run heavy gas oil with a fine
powdered catalyst in the presence of extreme heat (650 degrees farenheit to
1,050 degrees farenheit).  The larger hydrocarbon molecules "crack apart"
under such conditions, and can then be fractionated into light gases,
gasoline and light and heavy cycle oils.  Spent catalyst is delivered to a
regenerator where carbon deposits are burned so the catalyst can be used
again.

Delayed Coker Unit.  Delayed coking is a thermal cracking process in which
residual substances are heated to high temperatures and allowed time to
decompose into hydrocarbon vapors and a solid residue coke product.  A full
range of light hydrocarbon gases, including hydrogen and olefins, are
produced by the coking reaction.  These gases, in addition to gasoline
boiling range material ("naphtha") cracked products, are compressed and
cooled at sufficiently high pressure to condense the volatile light
hydrocarbons.  The liquified petroleum gases are then routed to an Alkylation
Unit, which is described below.  Coker gas oil is produced as a side product
from the coker fractionator with a vaporization temperature of approximately
900 degrees Farenheit.  This oil is routed to the FCCU. Petroleum coke from
the Delayed Coker Unit is used for fuel, for electrodes and for special
purposes such as manufacturing graphite.

Catalytic Reformer Unit.  The Catalytic Reformer Unit upgrades the octane
of the naphtha produced in the Delayed Coker Unit.  The octane of the
naphtha is approximately 52, compared with the average refinery gasoline
pool octane of 87.9.  Straight-run and cracked refinery naphthas boiling
between 160 degres Farenheit and 390 degrees Farenheit are catalytically
reformed to improve motor fuel properties.  Prior to entering the Catalytic
Reformer Unit, naphtha is fractionated into light, medium and heavy naphtha
streams.  The two lighter streams are selectively blended into gasoline and
military jet fuel.  The heavy naphtha fraction is routed to a naphtha
hydro-treating unit prior to catalytic reforming.  The principal product of
the reformer is reformat, a high octane gasoline blending stock.

Alkylation Unit.  The Alkylation Unit is used to alkylate or chemically
combine isobutane with propylene and butylene to form high octane gasoline. 
The process utilizes hydrofluoric acid or sulfuric acid as the alkylation
catalyst.  The feedstock for the Alkylation Unit is produced by the FCCU
and the Delayed Coker Unit and contains saturated propane, isobutane, and
normal butane in addition to propylene and butylene.  The feed stream also
contains significant amounts of hydrogen sulfide, which is extracted and
routed to a sulfur recovery unit.  The reactor effluent is partially
vaporized through a heat exchanger to provide refrigeration for the
reactor-contractor.  The vapors are compressed and then fractionated into
propane, isobutane and normal butane, and alkylate.  

Butamer Unit.  A Butamer Unit converts normal butane to isobutane.  A
refinery needs a source of supplemental isobutane on a year-round basis to
balance the requirements of the Alkylation Unit.  Most of the normal butane
produced in a refinery is blended into gasoline to increase vapor pressure. 
During the summer months, when gasoline vapor pressure specifications are low,
the refinery generally has adequate or surplus supplies of normal butane.
During the winter months, when gasoline vapor pressure specifications are
high, a refinery buys normal butane from outside sources.  

Process Heaters.  A process heater is a large, specialized furnace used to
heat hydrocarbons to varying temperatures within each of the refining units
described above.  Each of such units includes at least one heater, and
frequently includes several heaters.

Hydrocarbon Process Services

The Company's principal refinery services include turnarounds for the
complete refinery with integrated process units, the FCC Units within a
refinery, and complete construction and maintenance services.

Turnarounds

FCCU Turnarounds.  The Company's principal refinery operations involve
turnarounds of FCCUs.  FCCUs require a high level of maintenance because of
the extremely high temperatures inside the unit - in excess of 1000 degrees
Farenheit - and due to abrasive catalysts flow and their many internal
parts, which consist generally of stainless steel components and refractory
lined systems. Refractory is a heat and erosion resistant lining that
insulates the inner shell of the unit vessels.  The main pieces of equipment
in an FCCU are the reactor, the regenerator and the flue gas handling system.
Most of the repair and revamp work during a turnaround is performed on this
equipment. Major revamp work is required to increase efficiencies of the FCCU
with changing technology and to reduce air pollution from the unit, as required
by constantly changing laws.   In most cases, the mechanical work - involving
the disassembly and repair of the unit components - and the refractory work -
involving the installation of the refractory material onto the inside of
the units vessels - is performed by different contractors.  The Company
provides all of these services. Total Unit Turnarounds.  The Company also
performs total unit turnarounds involving maintenance of crude distillation
units, catalytic reformer units, delayed coker units, alkylation units,
reformers,  FCCUs and butamer units. These services also involve the
maintenance and modification of heat exchangers, heaters, vessels and
piping.

Heat Exchanger Services

The Company provides heat exchanger service to the refining industry,
which involves the removal, testing, repairing and reinstallation of heat
exchangers.  The Company owns specialized equipment to extract and reinstall
heat exchangers from both ground levels and aerial installations. In addition,
the Company owns retubing equipment, hydraulic bolt torquing equipment and
specialized transport carriers for moving these heat exchangers throughout
the facilities.  

Process Heaters

The Company constructs new refinery process heaters and repairs and revamps
existing heaters.  These units require skilled craftsmen and supervisors
and specialized construction techniques.  Through associations with various
heater manufacturing companies, the Company also offers turnkey fabrication
and erection of process heaters.  The Company has performed field erection
work for most of the major heater design companies in the U.S.

Other Support Services

Emergency Response Services.  The Company also performs substantial repair
and revamp services in connection with refinery unit failures, fires,
explosions and other accidents.  The Company believes that it has enhanced
its relationships with its customers by responding quickly to these types of
emergencies and by providing timely repair services, returning the affected
plants to normal operations without substantial delays.  

Manufacturing.  The Company owns and operates a 40,000 square foot fabrication
shop in Tulsa, Oklahoma and operates a 30,000 square foot facility in
Bellingham, Washington and a 12,000 square foot facility in Carson, California
that it uses to support its turnaround projects.  At these facilities, the
Company constructs piping,heater coils and components, and FCCU equipment
installed during turnarounds.  The Company also performs emergency fabrication
at these facilities when necessary to assist its customers.  In many instances,
the facilities are operated 24 hours per day to assist a turnaround project.

Refractory.  The Company also owns and operates a 15,000 square foot shop,
located at the Tulsa, Oklahoma facility used for performing refractory
installation.  The shop, which supports the Company's mechanical turnaround
services, contains specialized equipment and is operated by the Company's
refractory department.

ASME Code Stamp Services.  The Company is qualified to perform services on
equipment that contains American Society of Mechanical Engineer Code Stamps
("ASME codes").  Many state agencies and insurance companies require that
qualified ASME code installers perform services on ASME coded equipment. 
Many of the Company's competitors are not ASME code qualified, which forces
them to subcontract portions of a project involving work with coded equipment.

Daily and Routine Supplemental Maintenance.  The Company provides supplemental
and routine daily maintenance services for operating refineries.  Daily work
crews at the refineries range in size from 120 to over 165 per refinery.
The Company provides a wide range of supplemental services including equipment
operations and complete daily maintenance services and repairs.  Moreover,
the pressure to reduce the overall cost of maintaining the refineries has
initiated a trend of restructuring the daily and routine maintenance forces.
Refineries are seeking outside supplemental maintenance forces with proven
programs for increasing unit and equipment reliability, and a history of
performing work safely.  The Company has entered into two multi-year
maintenance agreements.  The Company believes there is a substantial market
for a quality maintenance workforce that places an emphasis on safety and
that can forge partnerships with refinery personnel to reduce maintenance
expenses.

Other Business Matters

Customers and Marketing

The Company derives most of its revenues from performing services for the
major integrated oil companies.  The Company also performs services for
independent petroleum refining and marketing companies, architectural and
engineering firms and for several major petrochemical companies.  In
addition, the Company builds water tanks for private and municipal water
facilities.  The Company is typically engaged by the manager of the facility
at which the work is being performed, although on occasion the Company
contracts with one of its customers to perform services at several facilities.

The Company did not have any one customer accounting for more than 10% of
revenues in 1997 and 1995.  During fiscal 1996, ARCO USA accounted for more
than 10% of the Company's revenues.  The Company sold its products and
services to approximately 311 customers during fiscal 1997.

The Company markets its services and products primarily through its marketing
personnel, senior professional staff and its management.  The marketing
personnel concentrate on developing new customers and assist management and
staff with existing customers.  The Company generally is required to bid
competitively for work on a project-by-project basis.  Projects are typically
awarded after a bidding process spanning two weeks to four months, and are
generally awarded based on price considerations, work quality, safety and
efficiency.  The Company bids for projects on both a fixed price basis and
on a detailed time and materials basis.  During 1997 the Company entered
into an alliance contract with a major oil company to be the sole supplier
of tank repair and maintenance services for this customer.  The Company has
had discussions with other customers for maintenance alliances.

Competition

The AST and refinery service industries are highly fragmented and
competition is intense within these industries.  Competition is based on,
among other factors, work quality and timeliness of performance, safety and
efficiency, availability of personnel and equipment, and price.  The
Company believes that its expertise and its reputation for providing timely
services allow it to compete effectively.  Although many companies that are
substantially larger than the Company have entered the market from time to
time in competition with the Company, the Company believes that the level
of expertise necessary to perform complicated, on-site maintenance and
construction operations presents an entry barrier to these companies and
other competitors with less experience than the Company.

Backlog

At May 31, 1997, the Company had an estimated backlog of work under
contracts believed to be firm of approximately $ 69.1 million, as compared
with an estimated backlog of approximately $71.9 million as of May 31,
1996.  Virtually all of the projects comprising this backlog are expected
to be completed within fiscal year 1998. Because many of the Company's
contracts are performed within short time periods after receipt of an
order, the Company does not believe that the level of its backlog is a
meaningful indicator of its sales activity. 

Insurance

The Company maintains worker's compensation insurance, general liability
insurance and auto liability insurance in the primary amount of $2.0
million, and an umbrella policy with coverage limits of $ 20.0 million in
the aggregate.  The Company also maintains policies to cover its equipment
and other property with coverage limits of $59.9 million and policies for
care, custody and control with coverage limits of $2.7 million in the
aggregate.  Most of the Company's policies provide for coverage on an
occurrence basis, not a "claims made" basis.  The Company's liability
policies are subject to certain deductibles, none of which is higher than
$100,000.  The Company maintains a performance and payment bonding line of
$45.0 million.  The Company also maintains key-man insurance policies
covering certain of its executive officers, and professional liability
insurance.

Many of the Company's contracts require it to indemnify its customers for
injury, damage or loss arising in connection with their projects, and
provide for warranties of materials and workmanship.  There can be no
assurance that the Company's insurance coverage will protect it against
the incurrence of loss as a result of such contractual obligations.
                                                  

Employees

At May 31, 1997, the Company had approximately 272 non-field, full-time
employees.  The Company also employed up to approximately 1,174 additional
persons on a project-by-project basis during fiscal  1997.  In its refinery
turnaround operations, the Company employed up to approximately 830 persons
at its job sites during the most active periods of 1997.  Approximately 361
of the employees of Matrix Service Mid-Continent, Inc., a subsidiary of the
Company, are covered by a collective bargaining agreement.  In addition,
substantially all of the temporary employees of Midwest are employed under
collective bargaining agreements.  The Company believes that its relations
with its employees are good, and has not experienced any significant strikes
or work stoppages.

Patents and Proprietary Technology

The Company holds two issued U.S. patents, which cover its Flex-A-Seal and
Flex-A-Span roof seal products.  The Company's Flex-A-Seal patent is held
jointly with an English company, which markets the Flex-A-Seal products in
the United Kingdom.  The Flex-A-Seal patent expires in August 2000 and the
Flex-A-Span patent expires in August 2008.  The Company also holds the
patents for Flex-A-Seal and Flex-A-Span in Holland and in Canada.  The
Company holds a U.S. patent which covers its ThermoStor, a diffuser system
that receives, stores and dispenses both chilled and warm water in and from
the same storage tank.  The ThermoStor patent expires in March 2010.  The
Company also holds a patent for a Floating Deck Support Apparatus for
aluminum roofs.  This patent expires on January 24, 2001. The Company has
applied for patents for two other products it has developed.  The Company
has developed the RS 1000 Tank Mixer which controls sludge build-up in crude
oil tanks through resuspension.  Also the Company has designed the Firesafe
which is an environmentally safe alternative to underground storage tanks
that meets the stringent requirements of UFC 77-203 (d)(2), NFPA 30, EPA and
Underwriter's Laboratories.  While the Company believes that the protection
of its patents is important to its business, it does not believe that these
patents are essential to the success of the Company.  

Regulation

Various environmental protection laws have been enacted and amended during
the past 20 years in response to public concern over the environment.  The
operations of the Company and its customers are subject to these evolving
laws and the related regulations, which are enforced by the EPA and various
other federal, state and local environmental, safety and health agencies
and authorities. Although the Company believes that its operations are in
material compliance with such laws and regulations, there can be no
assurance that significant costs and liabilities will not be incurred due
to increasingly stringent environmental restrictions and limitations. 
Historically, however, the cost of measures taken to comply with these laws
has not had a material adverse effect on the financial condition of the
Company.  In fact, the proliferation of such laws has led to an increase in
the demand for some of the Company's products and services.  A discussion
of the principal environmental laws affecting the Company and its customers
is set forth below.

Air Emissions Requirements.  The EPA and many state governments have
adopted legislation and regulations subjecting many owners and operators of
storage vessels and tanks to strict emission standards.  The regulations
prohibit the storage of certain volatile organic liquids ("VOLs") in
open-top tanks and require tanks which store VOLs to be equipped with primary
and/or secondary roof seals mounted under a fixed or floating roof.  Related
regulations also impose continuing seal inspection and agency notification
requirements on tank owners and prescribe certain seal requirements.  Under
the latest EPA regulations, for example, floating roofs on certain large
tanks constructed or modified after July 1984 must be equipped with one of
three alternative continuous seals mounted between the inside wall of the
tank and the edge of the floating roof.  These seals include a foam or
liquid-filled seal mounted in contact with the stored petroleum product; a
combination of two seals mounted one above the other, the lower of which
may be vapor mounted; and a mechanical shoe seal, composed of a metal sheet
held vertically against the inside wall of the tank by springs and
connected by braces to the floating roof.  The EPA is in the process of
developing further regulations regarding seals and floating roofs.

Though Company facilities themselves are generally not subject to such
requirements, these and other similar regulations have resulted in the
implementation of ongoing tank maintenance and inspection programs by
many owners and operators of ASTs.  These programs also generally result
in additional tank repairs, maintenance and modifications which provide a
market for the Company's services.

Amendments to the federal Clean Air Act adopted in 1990 require, among
other things, that refineries produce cleaner burning gasoline for sale
in certain large cities where the incidence of volatile organic compounds
in the atmosphere exceeds prescribed levels leading to ozone depletion.
Refineries are undergoing extensive modifications to develop and produce
acceptable reformulated fuels that satisfy the Clean Air Act Amendments.
Such modifications are anticipated to cost refineries several billion dollars,
and require the use of specialized construction services such as those provided
by the Company.  A significant number of refineries have completed changes to
produce "reformulated fuels", principally refineries serving specific areas
of the U.S.; however, there are a substantial number of refineries that have
not made the change.

Water Protection Regulations.   Protection of groundwater and other water
resources from spills and leakage of hydrocarbons and hazardous substances
from storage tanks and pipelines has become a subject of increasing legislative
and regulatory attention,  including releases from ASTs.  Under federal Clean
Water Pollution Control Act regulations, owners of  most ASTs are required to
prepare spill prevention, control and countermeasure ("SPCC") plans detailing
steps that have been taken to prevent and respond to spills and to provide
secondary containment for the AST to prevent contamination of soil and
groundwater.  These plans are also subject to review by the EPA, which has
authority to inspect covered ASTs to determine compliance with SPCC
requirements.  Various states have also enacted groundwater legislation that
has materially affected owners and operators of petroleum storage tanks.
The adoption of such laws has prompted many companies to install double
bottoms on their storage tanks to lessen the chance that their facilities
will discharge or release regulated chemicals.  State statutes regarding
protection of water resources have also induced many petroleum companies
to excavate product pipelines located in or near marketing terminals, to
elevate the pipelines aboveground and to install leak detection systems
under the pipelines.  These laws and regulations have generally led to an
increase in the demand for some of the Company's products and services.

In the event hydrocarbons are spilled or leaked into groundwater or surface
water from an AST that the Company has constructed or repaired, the Company
could be subject to lawsuits involving such spill or leak.  To date, the
Company has not suffered a material loss resulting from such litigation. 

Hazardous Waste Regulations.  The Resource Conservation and Recovery Act of
1976 ("RCRA") provides a comprehensive framework for the regulation of
generators and transporters of hazardous waste, as well as persons engaged
in the treatment, storage and disposal of hazardous waste. Under state and
federal regulations, many generators of hazardous waste are required to
comply with a number of requirements, including the identification of such
wastes, strict labeling and storage standards, and preparation of a manifest
before the waste is shipped off site.  Moreover, facilities that treat, store
or dispose of hazardous waste must obtain a RCRA permit from the EPA, or
equivalent state agency, and must comply with certain operating, financial
responsibility and site closure requirements.

In 1990, the EPA issued its Toxicity Characteristic Leaching Procedure
("TCLP") regulations.  Under the TCLP regulations, which have been amended
from time to time, wastes containing prescribed levels of any one of 
several identified substances, including organic materials found in
refinery wastes and waste-waters (such as benzene), will be characterized
as "hazardous" for RCRA purposes.  As a result, some owners and operators
of facilities that produce hazardous wastes  are being required  to make
modifications to their facilities or operations in order to remain outside
the regulatory framework or to come into compliance with the Subtitle C
requirements.   Many petroleum refining, production, transportation and
marketing facilities  are choosing to replace existing surface impoundments
with storage tanks and to equip certain of the remaining impoundments with
secondary containment systems and double liners.  Accordingly, the Company
believes that the promulgation of the TCLP regulations are having a
positive impact on its tank construction and modification business.

Amendments to RCRA require the EPA to promulgate regulations banning the
land disposal of hazardous wastes, unless the wastes meet certain treatment
standards or the particular land disposal method meets certain waste
containment criteria.  Regulations governing disposal of wastes identified
as hazardous under the TCLP, for example, could require water drained from
the bottom of many petroleum storage tanks to be piped from the tanks to a
separate facility for treatment prior to disposal.  Because the TCLP
regulations can, therefore, provide an incentive for owners of petroleum
storage tanks to reduce the amount of water seepage in the tanks, the
Company believes that the regulations have and will continue to positively
influence sales of its Flex-A-Seal roof seals, which materially reduce the
amount of water seepage into tanks.

CERCLA.  The Comprehensive Environmental Response, Compensation and
Liability Act of 1980 ("CERCLA"), also known as "Superfund",  authorizes
the EPA to identify and clean up sites contaminated with hazardous
substances and to recover the costs of such activities, as well as damages
to natural resources, from certain classes of persons specified as liable
under the statute.  Such persons include the owner or operator of a site
and companies that disposed or arranged for the disposal of hazardous
substances at a site.  Under CERCLA, private parties which incurred
remedial costs may also seek recovery from statutorily responsible persons.

Liabilities imposed by CERCLA can be joint and several where multiple
parties are involved.  Many states have adopted their own statutes and
regulations to govern investigation and cleanup of, and liability for,
sites contaminated with hazardous substances or petroleum products.  

Although the liabilities imposed by CERCLA (and other environmental
legislation) are more directly related to the activities of the Company's
clients, they could under certain circumstances give rise to liability on
the part of the Company if the Company's efforts in completing client
assignments were considered arrangements related to the transport or
disposal of hazardous substances belonging to such clients.  In the opinion
of management, however, it is unlikely that the Company's activities will
result in any liability under either CERCLA or other environmental regulations
in an amount which will have a material adverse effect on the Company's
operations or financial condition, and management is not aware of any current
liability of the Company based on such a theory.

Oil Pollution Act.  The Oil Pollution Act of 1990 ("OPA") established a new
liability and compensation scheme for oil spills from onshore and offshore
facilities.  Section 4113 of the OPA directed the President to conduct a
study to determine whether liners or other secondary means of containment
should be used to prevent leaking or to aid in leak detection at onshore
facilities used for storage of oil.  The Company believes that its business
would be positively affected by any regulations eventually promulgated by
EPA that required liners and/or secondary containment be used to minimize
leakage from ASTs.  While the regulation has not, to date, been enacted, the
industry designs secondary containment in all new tanks being built and, in
general, secondary containment is installed in existing tanks when they are
taken out of service for other reasons, in anticipation of this regulation.

Health and Safety Regulations.  The operations of the Company are subject
to the requirements of the Occupational Safety and Health Act ("OSHA") and
comparable state laws.  Regulations promulgated under OSHA by the
Department of Labor require employers of persons in the refining and
petrochemical industries, including independent contractors, to implement
work practices, medical surveillance systems, and personnel protection
programs in order to protect employees from workplace hazards and exposure
to hazardous chemicals.  In addition, in response to recent accidents in the
refining and petrochemical industries, new legislation and regulations
including OSHA's Process Safety Management Standard ("PSM") requiring
stricter safety requirements have been enacted.  Under PSM, employers and
contractors must ensure that their employees are trained in and follow all
facility work practices and safety rules and are informed of known potential
hazards.  The Company has established comprehensive programs for complying
with health and safety regulations.  While the Company believes that it
operates safely and prudently, there can be no assurance that accidents will
not occur or that the Company will not incur substantial liability in
connection with the operation of its business.

The State of California has promulgated particularly stringent laws and
regulations regarding health and safety and environmental protection.  The
Company's operations in California are subject to strict oversight under
these laws and regulations and the failure to comply with these laws and
regulations could have a negative impact on the Company.

Dividend Policy

The Company has never paid cash dividends on its Common Stock.  The Company
currently intends to retain earnings to finance the growth and development
of its business and does not anticipate paying cash dividends in the
foreseeable future.  Any payment of cash dividends in the future will
depend upon the financial condition, capital requirements and earnings of
the Company as well as other factors the Board of Directors may deem
relevant.  Certain of the Company's credit agreements restrict the
Company's ability to pay dividends.

Management's Discussion and Analysis of Financial Condition and Results of
Operations."  

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations General The Company was organized in October 1989 to become a holding company of Matrix and Petrotank. The discussion and analysis presented below is of the consolidated financial statements of these companies and the Company's other subsidiaries since the date of acquisition, including (i) Tank Supply, Inc., (ii) after October 3, 1990, Midwest, (iii) after June 1, 1991, San Luis, (iv) after December 30, 1992, Colt, (v) after June 10, 1993, Heath, (vi) after April 1, 1994, Brown, and (vii) after August 26, 1994, Mayflower. The Company recognizes revenues from fixed price contracts using the percentage of completion accounting method which measures progress on an uncompleted contract based on the amount of costs incurred for such project compared with the total amount of costs expected to be incurred through the completion of the project. Revenues from cost-plus-fee contracts are recognized on the basis of costs incurred plus the estimated fee earned. The Company has experienced an increase in revenues during two of the last three fiscal years. For fiscal 1995, Mayflower was included for nine months. All acquired companies were included for the full year for fiscal 1997 and 1996. Incremental revenues, gross profit and selling, general and administrative expenses attributable to the results of operations of acquired companies not included in the prior year are as follows: (in thousands) Year ended May 31, 1995 ------------ Revenues $765 Gross Profit 44 Selling, general & administrative expenses 35 The Company expects a continued demand for its services in the foreseeable future. Management believes that the percentage growth of its revenues for fiscal 1998 will be stronger than fiscal year 1997. The limitation to growth for the last three fiscal years was due to decreased demand for the Company's services. Limitations on growth capacity also reflect the seasonal nature of the Company's refinery turnaround activities, which creates pressure to expand the supervisory staff during the turnaround seasons. The Company continues to recruit, hire and train additional project engineers and project managers, and the Company's ability to continue to grow will depend, in part, on its ability to continue this process, and a stronger demand for the Company's services. The Company's quarterly results may tend to fluctuate from period to period, due primarily to the timing of turnarounds performed by the Company. Generally, the Company performs a substantial percentage of its turnaround projects in two periods February through May and September through November. Historically, these are the time periods when most refiners temporarily shutdown certain operating units for maintenance, repair or modification prior to changing their product mix in anticipation of a seasonal shift in product demand. Consequently, the Company's second quarter ending November 30 and its fourth quarter ending May 31 will typically include greater revenues from turnarounds than its first quarter or its third quarter. Results of Operations The following table presents, for the periods indicated, the percentage relationship which certain items in the Company's statement of operations bear to revenues, and the percentage increase or decrease in the dollar amount of such items. The following data should be read in conjunction with the financial statements of the Company and the notes thereto contained elsewhere in this Form 10-K. Revenues for fiscal year ending May 31, 1995 were positively affected by the inclusion of Mayflower for nine months. [CAPTION] Percentage of Revenues | Years ended May 31, | Period-to-Period Change -------------------------------------------------------------- | 1997 1996 | vs. vs. 1997 1996 1995 | 1996 1995 ---- ----- ----- | ----- ----- | Revenues........................... 100.0 % 100.0 % 100.0 % | (0.3)% 3.5 % | Cost of revenues................... 90.5 91.0 92.2 | (0.8) 2.1 | Gross profit....................... 9.5 9.0 7.8 | 5.0 19.4 | Selling, general and administrative | expenses....................... 6.0 5.9 6.2 | 2.7 (1.3) | Operating income................... 3.0 2.6 0.8 | 16.5 224.1 | Interest income.................... 0.1 0.2 0.1 | (60.1) 175.8 | Income before income tax | expense........................ 2.8 2.4 (0.3) | 16.3 1067.0 | Net income......................... 1.6 % 1.3 % (0.1) % | 21.8 % 1396.0 % ======= ======= ======= ======= ========
Fiscal 1997 Compared to Fiscal 1996 Revenues for the year ended May 31, 1997 were $183.1 million as compared to revenues of $183.7 million for the year ended May 31, 1996, representing a decrease of approximately $581 thousand or 0.3%. The decrease was primarily due to decreased revenues for the Company's services in aboveground storage tank markets primarily on the West and Gulf Coasts. The Company believes that the decrease in activity on the West Coast was due primarily to additional expenditures in the two prior years to comply with state environmental regulations with a compliance date of January 1, 1996. Gross profit increased to $17.4 million for the year ended May 31, 1997 from gross profit of $16.6 million for the year ended May 31, 1996, an increase of approximately $822 thousand or 5.0%. Gross profit as a percentage of revenues increased to 9.5% in the 1997 period from 9.0% for the 1996 period. The Company continues to experience pricing pressure as a result of intense competition in its established markets; however, the demand for the Company's services for capital projects has improved during the year. Customer inquiry levels and the available projects for repairs and maintenance and new construction of AST's and refinery maintenance have been improving during the year. Selling, general and administrative expenses increased to $11.1 million for the year ended May 31, 1997 from expenses of $10.8 million for the year ended May 31, 1996, an increase of $296 thousand or approximately 2.7%. The increase was due to an increase of certain administrative personnel and facilities in line with the increased revenues at the Company's Colt and Brown operations. Selling, general and administrative expenses as a percentage of revenues increased to 6.0% for fiscal 1997 from 5.9% for fiscal 1996. Operating income increased to $5.5 million for the year ended May 31, 1997 from $4.7 million for the year ended May 31, 1996, an increase of $777 thousand or approximately 16.5%. The increase was due to improved gross profit margin and a decrease in amortization of intangible assets. Due to changes in the economic conditions in Saudi Arabia, there is a shortage of work available of the nature performed by the foreign joint venture Al Shafai-Midwest Constructors, Ltd. It is management's opinion that those conditions will last for several years. The venture partners, Saud Al Shafai and Sons Contractors and the Company, are in the process of liquidating the joint venture. At May 31, 1995, the Company had reduced its carrying value of the investment in this joint venture to the estimated recovery amount upon completion of the liquidation. The Company recorded a loss of $1.4 million for the year ended May 31, 1995. The Company had no expenses related to the joint venture for the year ended May 31, 1997 and 1996. Interest income decreased to $164 thousand for the year ended May 31, 1997 from $411 thousand for the year ended May 31, 1996. This decrease resulted from interest earned on the refund of certain state and federal income taxes received during the previous year. Interest expense decreased to $536 thousand for the year ended May 31, 1997 from $815 thousand of interest expense for the year ended May 31, 1996. The decrease resulted primarily from decreased borrowing under the Company's revolving credit facility. Under this facility, a $4.9 million term loan was made to the Company on October 5, 1994, and $2.4 million remains outstanding at May 31, 1997. Net income increased to $3.0 million for the 1997 period from $2.4 million for the 1996 period. The increase was due to improved gross profit margin, and decreased amortization of intangible assets, as compared with the prior year. Fiscal 1996 Compared to Fiscal 1995 Revenues for the year ended May 31, 1996 were $183.7 million as compared to revenues of $177.5 million for the year ended May 31, 1995, representing an increase of approximately $6.2 million or 3.5%. The increase was primarily due to increased revenues for the Company's services in both refinery maintenance and aboveground storage tank markets. Gross profit increased to $16.6 million for the year ended May 31, 1996 from gross profit of $13.9 million for the year ended May 31, 1995, an increase of approximately $2.7 million or 19.4%. Gross profit as a percentage of revenues increased to 9.0% in the 1996 period from 7.8% for the 1995 period. Selling, general and administrative expenses decreased to $10.8 million for the year ended May 31, 1996 from expenses of $10.9 million for the year ended May 31, 1995, a decrease of $143 thousand or approximately 1.3%. The decrease was due to areduction of certain administrative personnel. Selling, general andadministrative expenses as a percentage of revenues decreased to 5.9% for fiscal 1996 from 6.2% for fiscal 1995. Operating income increased to $4.7 million for the year ended May 31, 1996 from $1.5 million for the year ended May 31, 1995, an increase of $3.2 million or approximately 224.1%. The increase was due to increased revenue, improved gross profit margin, and decreases in selling, general and administrative expenses. Due to changes in the economic conditions in Saudi Arabia, there is a shortage of work available of the nature performed by the foreign joint venture Al Shafai-Midwest Constructors, Ltd. It is management's opinion that those conditions will last for several years. The venture partners, Saud Al Shafai and Sons Contractors and the Company, are in the process of liquidating the joint venture. At May 31, 1995, the Company had reduced its carrying value of the investment in this joint venture to the estimated recovery amount upon completion of the liquidation. The Company recorded a loss of $1.4 million for the year ended May 31, 1995. The Company had no expenses related to the joint venture for the year ended May 31, 1996. Interest income increased to $411 thousand for the year ended May 31, 1996 from $149 thousand for the year ended May 31, 1995. This increase resulted from interest earned on the refund of certain state and federal income taxes received during the year. Interest expense decreased to $815 thousand for the year ended May 31, 1996 from $897 thousand of interest expense for the year ended May 31, 1995. The decrease resulted primarily from decreased borrowing under the Company's revolving credit facility and a term loan established thereunder. Under this facility, a $4.9 million term loan was made to the Company on October 5, 1994, and $3.5 million remains outstanding at May 31, 1996. Net income increased to $2.4 million for the 1996 period from a net loss income of $189 thousand for the 1995 period. The increase was due to improved gross profit margin, decreased selling, general and administrative expenses, and no losses from investment in foreign joint venture as compared with the prior year. Liquidity and Capital Resources The Company's cash and cash equivalents totaled approximately $1.9 million at May 31, 1997 and 1996. The Company has financed its operations recently with cash generated by operations and advances under the Company's credit facility. The Company has a credit facility with a commercial bank under which the Company may borrow a total of $20.0 million. The Company may borrow up to $15.0 million under a revolving credit agreement based on the level of the Company's eligible receivables. The agreement provides for interest at the Prime Rate minus one-half of one percent (1/2 of 1%), or a LIBOR based option, and matures on October 31, 1999. At May 31, 1997, the outstanding advances under the revolver totaled $5.0 million. The interest rate for this facility at May 31, 1997 was: 1) Prime Option 8% on $2.0 million and 2) LIBOR Option 7.2% on $3.0 million. The credit facility also provides for a term loan up to $5.0 million. On October 5, 1994, a term loan of $4.9 million was made to the Company. The term loan is due on August 31, 1999 and is to be repaid in 54 equal payments beginning in March 1995 at an interest rate based upon the Prime Rate or a LIBOR Option. At May 31, 1997 the balance outstanding on this facility was $2.45 million. The interest rate at May 31, 1997 was 1) Prime Option of 8.5% on $450 thousand and 2) LIBOR Option of 7.8% on $2.0 million. Operations of the Company provided $6.2 million of cash for the year ended May 31, 1997 as compared with providing $9.6 million of cash for the year ended May 31, 1996, representing a decrease of approximately $3.4 million. The decrease was due to a decrease of $6.3 million from the collection of accounts, a decrease of $1.9 million from prepaid expenses and inventory, a decrease related to income taxes and other accrued liabilities of $5.5 million, and a decrease of $486 thousand from depreciation and amortization. These decreases are net of increased net income of $535 thousand, a net increase of $5.2 million of costs and estimated earnings in excess of billings on uncompleted contracts and billings on uncompleted contracts in excess of costs and estimated earnings, and a $5.0 million increase from accounts payable. Capital expenditures during the year ended May 31, 1997 totaled approximately $5.8 million. Of this amount, approximately $998 thousand was used to purchase trucks for field operations, and approximately $1.9 million was used to purchase welding, construction, and fabrication equipment. The Company has expended $2.5 million on land and construction of a new facility in the Northwest. The Company has invested approximately $426 thousand in furniture and fixtures during the year, which includes approximately $319 thousand invested in computer equipment for operations and automated drafting. The Company has currently budgeted approximately $5.6 million for capital expenditures for fiscal 1998. The Company expects to be able to finance these expenditures with working capital and borrowings under the Company's credit facility. The Company believes that its existing funds, amounts available from borrowings under its existing credit facility, and cash generated by operations will be sufficient to meet the Company's working capital needs at least through fiscal 1998 and possibly thereafter unless significant expansions of operations not now planned are undertaken, in which case the Company would arrange additional financing as a part of any such expansion. Other In March 1995, the Financial Accounting Standards Board (FASB) issued Statement No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of," which required impairment losses to be recorded on long-lived assets used in operations when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the assets' carrying amount. Statement 121 also addresses the accounting for long-lived assets that are expected to be disposed of. The Company adopted Statement 121 in the first quarter of 1997. The adoption of Statement 121 did not have a significant impact on the Company's financial statements. In February 1997, the Financial Accounting Standards Board issued Statement No. 128, "Earnings Per Share," which is required to be adopted on December 31, 1997. At that time, the Company will be required to change the method currently used to compute earnings per share and to restate all prior periods. Under the new requirements for calculating primary earnings per share, the dilutive effect of stock options will be excluded. The impact on earnings per share for the year ended May 31, 1997 would have been an increase of $0.01 per share for both basic and diluted shares. Certain Factors Influencing Results and Accuracy of Forward-Looking Statements This Annual Report contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933. Discussions containing such forward-looking statements may be found in the material set forth under "Business" and "Management's Discussion and Analysis of Financial Condition and Results of Operations," as well as within the Annual Report generally. In addition, when used in this Annual Report, the words "believes", "anticipates", "expects" and similar expressions are intended to identify forward-looking statements. In the normal course of its business, the Company, in an effort to help keep it shareholders and the public informed about the Company's operations, may from time to time issue certain statements, either in writing or orally, that contain or may contain forward-looking information. Generally, these statements relate to business plans or strategies, projected or anticipated benefits or other consequences of such plans or strategies, or projections involving anticipated revenues, earnings or other aspects of operating results. Such forward-looking statements are subject to a number of risks and uncertainties. As noted elsewhere in this Annual Report, all phases of the Company's operations are subject to a number of uncertainties, risks and other influences, many of which are beyond the control of the Company, and any one of which, or a combination of which, could materially affect the results of the Company's operations and whether forward-looking statements made by the Company ultimately prove to be accurate. The following discussion outlines certain factors that in the future could affect the Company's consolidated results and cause them to differ materially from those that may be set forth in any forward-looking statement made by or on behalf of the Company. The Company cautions the reader, however, that this list of risk factors may not be exhaustive. Competition. The Company competes with numerous large and small companies, some of which have greater financial and other resources than the Company. Competition within both the aboveground storage tank and hydrocarbon process services business is intense and is based on quality of service, price, safety considerations and availability of personnel. See "Business- Other Business Matters-Competition." Market Factors. The Company is dependent on the petroleum storage operations of the petroleum industry, and a downturn in that industry could negatively affect its operations. The Company's hydrocarbon processing operations focus primarily on the refining industry. The refining industry has undergone significant changes in the past decade with respect to product composition, costs of petroleum products, and refinery capacity and utilization. Although the Company believes that these changes in the industry have positively affected its business, changes could occur that decrease the industry's dependence on the type of services the Company provides. See "Business- Aboveground Storage Tank Operations-Hydrocarbon Process Services." Availability of Supervisory Personnel. The Company employs in its operations project supervisors with substantial experience and training. The growth of the business will depend on, and may be restricted by, its ability to retain these personnel and to recruit and train additional supervisory employees. The competition to recruit qualified supervisor staff is intense. Labor Markets. The operations of the Company are labor intensive. The Company has employed up to 650 workers for a single project, and many of the workers employed by the Company are represented by labor unions and covered by collective bargaining agreements. Although the Company has to date been able to employ sufficient labor to complete its projects, changes in labor market conditions could restrict the availability of workers or increase the cost of such labor, either of which could adversely affect the Company. In addition, the operations of the Company could be adversely affected by a strike or work stoppage. See "Business-Other Business Matters-Employees." Fluctuations in Quarterly Results. The operating results of hydrocarbon process services may be subject to significant quarterly fluctuations, affected primarily by the timing of planned maintenance projects at customers' facilities. Generally, the Company's turnaround projects are undertaken in two primary periods-February through May and September through November- when refineries typically shut down certain operating units to make changes to adjust to seasonal shifts in product demand. As a result, the Company's quarterly operating results can fluctuate materially. See "Management's Discussion and Analysis of Financial Condition and Results of Operations of the Company." Environmental Regulation. The operations of the Company have been affected positively by the promulgation of more stringent environmental laws and more stringent enforcement of existing laws. Although the Company's future business success is not dependent on increased environmental regulation, decreased regulation and enforcement could adversely affect the demand for the services provided by the Company. See "Business-AST Market and Regulatory Background- Other Business Matters." Potential Liability and Insurance. The operations of the Company involve the use of heavy equipment and exposure to construction hazards, with attendant significant risks of liability for personal injury and property damage. While the Company believes that it operates safely and prudently, there can be no assurance that accidents will not occur or that the Company will not incur substantial liability in connection with the operation of its business. In addition, recent accidents within the refining and petrochemical industries may result in additional regulation of independent contractors serving those industries. See "Business-Other Business Matters-Regulation." The Company maintains workers compensation insurance, general liability insurance and auto liability insurance, but such insurance is subject to coverage limits of $2.0 million per accident or occurrence. The Company also maintains an umbrella policy with coverage limits of $20.0 million in the aggregate. Such insurance includes coverage for losses or liabilities relating to environmental damage or pollution. Although the Company believes that it conducts its operations prudently and that it minimizes its exposure to such risks, the Company could be materially adversely affected by a claim that was not covered or only partially covered by insurance. See "Business-Other Business Matters-Insurance." Item 8. Financial Statements and Supplementary Data Reference is made to the financial statements, the report thereon, the notes thereto and supplementary data commencing at page 1 of this Annual Report on Form 10-K, which financial statements, report, notes and data are incorporated herein by reference.

[DESCRIPTION] Matrix Service Company Notes to Consolidated Financial Statements 1. Summary of Significant Accounting Policies Organization and Basis of Presentation The consolidated financial statements present the accounts of Matrix Service Company ("MSC") and its subsidiaries (collectively referred to as "the Company"). Subsidiary companies include Matrix Service, Inc., ("Matrix"), Midwest Industrial Contractors, Inc. ("Midwest"), Matrix Service Mid-Continent, Petrotank Equipment, Inc. ("Petrotank"), Tank Supply, Inc., San Luis Tank Piping Construction Co., Inc. ("San Luis"), Colt Construction Co. ("Colt"), Midwest International, Inc., Heath Engineering Ltd. ("Heath"), Brown Steel Contractors, Inc. ("Brown") and Mayflower Vapor Seals Corp. ("Mayflower"). Intercompany transactions and balances have been eliminated in consolidation. Mayflower was acquired on August 26, 1994 by MSC (see Note 3). The Company operates primarily in the United States but has operations in Canada and Mexico through Heath and San Luis. The Company's one industry segment is maintenance, construction services and products for petroleum refining and storage facilities and water storage tanks and systems for municipalities and private industry. Cash Equivalents The Company includes as cash equivalents all investments with original maturities of three months or less which are readily convertible into cash. The carrying value of cash equivalents approximates fair value. Inventories Inventories consist primarily of raw materials and are stated at the lower of cost or net realizable value. Cost is determined using the first-in, first-out or average cost method. Revenue Recognition Revenues from fixed-price contracts are recognized on the percentage-of- completion method measured by the percentage of costs incurred to date to estimated total costs for each contract. Revenues from cost-plus-fee contracts are recognized on the basis of costs incurred plus the estimated fee earned. Anticipated losses on uncompleted contracts are recognized in full when they become known. Losses from the investment in the undistributed equity of the foreign joint venture were recognized in accordance with the equity method of accounting in 1995. Depreciation and Amortization Depreciation is computed using the straight-line method over the estimated useful lives of the depreciable assets. Goodwill and noncompete agreements are being amortized over 40 and 5 years, respectively, using the straight- line method. Income Taxes The Company accounts for income taxes under Statement of Financial Accounting Standards No. 109, "Accounting for Income Taxes" ("SFAS 109"). Under SFAS 109, the deferred tax provision is determined under the liability method whereby deferred tax assets and liabilities are recognized based on differences between financial statement and tax bases of assets and liabilities using presently enacted tax rates. Net Income per Common and Common Equivalent Share Primary net income per common and common equivalent share is computed using the weighted average number of shares of common stock and common stock equivalents. Common stock equivalents consist of stock options (calculated using the treasury stock method). Fully diluted net income per common and common equivalent share is computed using the higher of year-end or average market price under the treasury stock method. Stock Option Plans The Company has elected to follow Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees" (APB 25), and related interpretations in accounting for its employee stock options because, as discussed in Note 6, the alternative fair value accounting provided for under FASB Statement No. 123, "Accounting for Stock-Based Compensation," requires use of option valuation models that were not developed for use in valuing employee stock options. Under APB 25, because the exercise price of the Company's employee stock options equals the market price of the underlying stock on the date of grant, no compensation expense is recognized. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. 2. Uncompleted Contracts Contract terms generally provide for progress billings based on completion of certain phases of the work. The excess of costs incurred and estimated earnings recognized for construction contracts over amounts billed on uncompleted contracts is reported as a current asset and the excess of amounts billed over costs incurred and estimated earnings recognized for construction contracts on uncompleted contracts is reported as a current liability as follows: May 31 1997 1996 ------------------ (In thousands)
Costs incurred and estimated earnings recognized on uncompleted contracts $104,746 $97,683 Billings on uncompleted contracts 109,770 89,914 ------------------- $ 5,024 $ 7,769 =================== Shown on balance sheet as: Costs and estimated earnings in excess of billings on uncompleted contracts $11,349 $12,122 Billings on uncompleted contracts in excess of costs and estimated earnings 6,325 4,353 ------------------- $ 5,024 $ 7,769 ===================
Approximately $4.2 million and $3.5 million of accounts receivable at May 31, 1997 and 1996, respectively, relate to billed retainages under contracts. 3. Acquisitions Mayflower Vapor Seals On August 26, 1994, the Company acquired certain assets of Mayflower Vapor Seals Corp. for $660,000. The transaction was accounted for as a purchase and resulted in approximately $442,000 of goodwill, which is being amortizedon a straight-line basis over a 40-year period. The operations of the newsubsidiary have been included in the accompanying financial statements subsequent to August 26, 1994. Pro forma results of operations for the year ended May 31, 1995, assuming Mayflower transaction occurred on June 1, 1994, were not significantly different from the results reported. Noncash Investing Activities At May 31, 1997, the Company has an earnout payable of $2.4 million for distributions which will be made pursuant to contingent consideration provisions of various business acquisition agreements. The earnout payable represents final settlement of the earnout agreement. 4. Long-Term Debt Long-term debt consists of the following: 1997 1996 ---------------- (In thousands)

In August 1994, the Company established a credit facility with a commercial bank under which the Company may borrow a total of $20 million. The Company may borrow up to $15 million under a revolving credit agreement based on the level of the Company's eligible accounts receivable, which was $31,769,000 at May 31, 1997. The agreement provides for interest at the Prime Rate (8.5% at May 31, 1997) minus one-half of one percent, or a LIBOR based option, (7.3% at May 31, 1997) and matures on October 31, 1999. The agreement requires maintenance of certain financial ratios, limits the amount of additional borrowings and prohibits the payment of dividends. Advances of $5 million were outstanding under this agreement at May 31, 1997. The credit facility also provides for a term loan up to $5 million. On October 5, 1994, a term loan of $4.9 million was made to the Company. The term loan is due on August 31, 1999 and is to be repaid in 54 equal payments beginning in March 1995 at an interest rate based upon the Prime Rate or LIBOR option. At May 31, 1997, the interest rates for this credit facililty were Prime Rate option of 8.0% on $2.0 million and LIBOR option of 7.2% on $3.0 million. At May 31, 1997, the balance outstanding on the term loan was $2,450,000 at Prime Rate option of 8.5% on $450 thousand and LIBOR option of 7.8% on $2.0 million. The credit facility is secured by all accounts receivable, inventory, intangibles, and proceeds related thereto. The Company has outstanding letters of credit and letters of guarantee totaling $3,337,718 which mature during 1997, 1998 and 1999. Aggregate maturities of long-term debt excluding the revolving note are as follows (in thousands): 1998 - $1,495; 1999 - $1,090; 2000 - $272; and 2001 - $0. The carrying value of debt approximates fair value. 5. Income Taxes The components of the provision for income taxes are as follows: 1997 1996 1995 --------------------------- (In thousands)
Current: Federal $1,825 $1,145 $ (83) State 443 373 (10) Foreign 218 165 (234) ---------------------------- 2,486 1,683 (327) Deferred: Federal (121) (21) 48 State (180) 368 11 Foreign (55) (81) 2 ---------------------------- (356) 266 61 ---------------------------- $2,130 $1,949 $(266) ============================
The difference between the expected tax rate and the effective tax rate is indicated below: 1997 1996 1995 ------------------------------- (In thousands)
Expected provision (benefit) for federal Income taxes at the statutory rate $1,739 $1,495 $(155) State income taxes, net of federal benefit 290 257 (8) Charges without tax benefit, primarily goodwill amortization 225 246 246 Life insurance proceeds - - (255) Other (124) (49) (94) ------------------------------- Provision for income taxes $2,130 $1,949 $(266)
The Company incurred pretax losses from foreign operations of $1,449,000 in 1996. Significant components of the Company's deferred tax liabilities and assets as of May 31, 1997 and 1996 are as follows: 1997 1996 ---------------- (In thousands)
Deferred tax liabilities: Tax over book depreciation $4,713 $5,055 Other - net 44 33 ----------------- Total deferred tax liabilities 4,757 5,088 Deferred tax assets: Foreign insurance dividend 275 287 Vacation accrual 205 203 Colt & Brown noncompete amortization 423 483 Other - net 118 (22) ----------------- Total deferred tax assets 1,021 995 ----------------- Net deferred tax liability $3,736 $4,093 ==================
The Company had operating loss carryforwards at May 31, 1995 attributable to foreign operations totaling $694,000 that were fully utilized during 1996. The Company has unused state job tax credit carryforwards of $369,000 at May 31, 1997. 6. Stockholders' Equity The Company has adopted a 1990 Incentive Stock Option Plan (the "1990 Plan") and a 1991 Incentive Stock Option Plan (the "1991 Plan") to provide additional incentives for officers and other key employees of the Company to promote the success of the business and to enhance the Company's ability to attract and retain the services of qualified persons. The Company has adopted a 1995 Nonemployee Directors' Stock Option Plan (the "1995 Plan") to promote the interests of the Company and its stockholders by helping to attract and retain highly qualified independent directors and allowing them to develop a sense of proprietorship and personal involvement in the development and financial success of the Company. Under the 1990 and 1991 Plans, incentive and nonqualified stock options may be granted to the Company's key employees and nonqualified stock options may be granted to nonemployees who are elected for the first time as directors of the Company after January 1, 1991. Options generally become exercisable over a five-year period from the date of the grant. Under the 1995 Plan, qualified stock options are granted annually to nonemployee directors. Stock options granted under the 1995 Plan generally become exercisable over a two-year period from the date of the grant. Under each plan, options may be granted with durations of no more than ten years. The option price per share may not be less than the fair market value of the common stock at the time the option is granted. Shareholders have authorized an aggregate of 1,250,000, 620,000, and 250,000 options to be granted under the 1990, 1991, and 1995 Plans, respectively. Options exercisable total 681,279 and 497,618 at May 31, 1997 and 1996, respectively. Pro forma information regarding net income and earnings per share is required by Statement 123, and has been determined as if the Company had accounted for its employee stock options under the fair value method of that Statement. The fair value for these options was estimated at that date of grant using a Black-Scholes option pricing model with the following weighted-average assumptions: risk-free interest rates of 5.70% to 6.62%; dividend yield of 0%; volatility factors of the expected market price of the Company's stock of .376 to .690; and an expected life of the options of 3.5 to 5 years. The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options which have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions including the expected stock price volatility. Because the Company's employee stock options have characeristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management's opinion, the existing models do not necessarily provide a reliable single measure of the fair value of its employee stock options. The effect on pro forma net income from the options is as follows: 1997 1996 ------------------------ (in thousands) Income before stock options $2,984 $2,449 Compensation expense from stock options: 1996 grant 231 78 1997 grant 38 - ------------------------ Net income $2,715 $2,371 ======================== Pro forma earnings per share: Primary .28 .25 Fully diluted .27 .25
The effect of compensation expense from stock options on 1996 pro forma net income reflects only the vesting of 1996 awards. However, 1997 pro forma net income reflects the second year of vesting of the 1996 awards and the first year of vesting of 1997 awards. The following summary reflects option transactions for the past three years: Option Price Shares Per Share --------------------------------
Shares under option: Balance at May 31, 1994 1,244,104 $ .67 - $11.25 Granted 1,390,525 3.63 11.25 Exercised (7,235) .67 - .80 Canceled (1,195,189) .80 - 11.25 -------------------------------- Balance at May 31, 1995 1,432,205 .67 - 11.25 Granted 391,500 3.63 - 6.25 Exercised (36,408) .67 - 3.63 Canceled (265,741) .80 - 5.75 -------------------------------- Balance at May 31, 1996 1,521,556 .67 - 6.25 Granted 113,000 5.88 - 7.875 Exercised (62,239) .67 - 6.250 Canceled (47,313) 3.63 - 6.25 -------------------------------- Balance at May 31, 1997 1,525,004 $ .67 - $ 7.875 ================================
7. Commitments The Company is the lessee under operating leases covering real estate in Tulsa, Oklahoma; Bristol, Pennsylvania; Anaheim, California; Bay Point, California; Paso Robles, California; Bellingham, Washington; and Carson, California. The Paso Robles lessors are former stockholders of San Luis, now a stockholder of the Company and parties related to him. In 1995 and 1994, the Bellingham lessors were former stockholders of Colt, who became a stockholder of the Company and parties related to him. The Company is also the lessee under operating leases covering office equipment. Future minimum lease payments are as follows (in thousands): 1998 - $517; 1999 - $372; 2000 - $279; 2001 - $239; 2002 - $89 and thereafter $154. Rental expense was $516,000, $646,000 and $663,000 for the years ended May 31, 1997, 1996 and 1995, respectively. Rental expense related to the Paso Robles lease was $149,000 for the year ended May 31, 1997 and 1996 and $120,000 for the years ended May 31, 1995. Rental expense related to the Bellingham lease was $57,000 for the years ended May 31, 1997, 1996 and 1995. 8. Discontinued Foreign Operations During 1993 the Company invested $662,000 to establish a joint venture (Al Shafai - Midwest Constructors) with a Saudi Arabian company to perform mechanical contracting services in the Kingdom of Saudi Arabia. Al Shafai- Midwest Constructors is 49% owned by Midwest International, Inc. The Company invested another $1,404,000 in the joint venture in 1994 and received $46,000 from the joint venture in 1995. The Company's 49% share of the losses was $349,000 and $200,000 for 1995 and 1994, respectively. Due to changes in economic conditions in Saudi Arabia, the Company and the Saudi Arabian company are in the process of liquidating the joint venture. The Company reduced the carrying value of its investment in this joint venture by $1,017,000 in 1995 to the estimated recovery upon completion of the liquidation. Effective February 29, 1996, the Company discontinued the operations of its United Kingdom tank maintenance subsidiary. As a result, assets totaling $426,000 were sold or written off. Remaining assets of $556,000 were transferred to other Company locations for use in operations. 9. Other Financial Information The Company provides specialized on-site maintenance and construction services for petrochemical processing and petroleum refining and storage facilities. The Company grants credit without requiring collateral to customers consisting of the major integrated oil companies, independent refiners and marketers, and petrochemical companies. Although this potentially exposes the Company to the risks of depressed cycles in oil and petrochemical industries, the Company's receivables at May 31, 1997 have not been adversely affected by such conditions and historical losses have been minimal. Sales to one customer accounted for approximately 11% of the Company's revenues for the year ended May 31, 1996. There were no sales to one customer in excess of 10% of for the years ended May 31, 1997 and 1995. Depreciation expense for the years ended May 31, 1997, 1996 and 1995 was $4.5 million, $4.7 million and $4.5 million, respectively. Amortization of goodwill and noncompete for the years ended May 31 ,1997, 1996 and 1995 was $864,000, $1.1 million and $1.5 million, respectively. 10. Employee Benefit Plan On June 1, 1993, the Company established a defined contribution 401(k) savings plan (the "Plan"). All employees meeting length of service requirements are eligible to participate in the Plan. Participants may contribute an amount up to 15% of pretax annual compensation as defined in the Plan, subject to certain other limitations in accordance with Section 401(k) of the Internal Revenue Code. The Company may match contributions at a percentage determined by the Company, but not to exceed 100% of the elective deferral contributions made by participants during the Plan year. The Company has made no matching contributions to the Plan for the years ended May 31, 1997, 1996, and 1995. 11. New Accounting Standard In March 1995, the Financial Accounting Standards Board (FASB) issued Statement No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of," which requires impairment losses to be recorded on long-lived assets used in operations when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the assets' carrying amount. Statement 121 also addresses the accounting for long-lived assets that are expected to be disposed of. The Company will adopt Statement 121 in the first quarter of 1997. The adoption of Statement 121 did not have a significant impact on the Company's financial statements. In February 1997, the Financial Accounting Standards Board issued Statement No. 128, "Earnings Per Share," which is required to be adopted on December 31, 1997. At that time, the Company will be required to change the method currently used to compute earnings per share and to restate all prior periods. Under the new requirements for calculating primary earnings per share, the dilutive effect of stock options will be excluded. The impact on earnings per share for the year ended May 31, 1997 would have been an increase of $.01 per share for both basic and diluted shares. 12. Contingent Liabilities The Company is self-insured for worker's compensation, auto, and general liability claims with stop loss protection at $250,000, $100,000, and $50,000 per incident, respectively. Management estimates the reserve for such claims based on knowledge of the circumstances surrounding the claims, the nature of any injuries involved, historical experience, and estimates of future costs provided by certain third parties. Accrued insurance at May 31, 1997 represents management's estimate of the Company's liability at that date. Changes in the assumptions underlying the accrual could cause actual results to differ from the amounts reported in the financial statements. 13. Subsequent Events On June 17, 1997, Matrix Service Company acquired the stock of General Service Corporation ("GSC") and it's affiliated companies, Maintenance Services Inc., Allentech, and Environmental Protection Services, Inc. for up to $7.8 million, subject to certain adjustments. The purchase price was payable in cash of $4.8 million, a $250,000 note payable in 12 quarterly installments. In addition, the stockholders of GSC are entitled to receive in the future up to an additional $2.75 million in cash if GSC satisfies certain earnings requirements. The transaction will be accounted for as a purchase and is expected to result in the creation of approximately $2.9 million of goodwill and noncompetition covenants of which $2.3 million, representing the goodwill, will be amortized over a 40-year period and the remaining balance will be amortized over a three-year period. GSC is engaged in the same line of business as Matrix Service Company.

                         Fiscal Year          Earnout
                         Ending May 31       Threshold
                         -------------       ---------

                             1998            2,000,000
                             1999            2,250,000

                             2004            2,500,000

Operations will be the greater of (a) $1,209,000 or (b) the EBIT from the

For purposes of calculating EBIT, no reduction shall be made for (1)
interest charges on any indebtedness, (2) costs attributable to the

(4) any management fees charged by Purchaser to the Earnout Companies that

maintenance, repair and seal jobs located in the Territory and (ii) all
jobs in the facilities currently owned and operated by British Petroleum,
Ashland Oil, IMTT, Mobil Team East, Citgo and Colonial Pipe Line.

In the event (i) that the Purchaser merges with or is acquired by another
company that is not an Affiliate of Purchaser or (ii) of the divestiture of
a material portion of the assets of the Earnout Companies, whether directly
or indirectly (through a transfer of such assets, a sale of stock, a merger
or otherwise), so as to, in the reasonable judgment of Sellers, have an
adverse effect on their receipt of the Maximum Earnout Payment (a "Change
in Control"), each Seller may, at such Seller's option, either:

(a) continue the Earnout as outlined in Section 1.4(c), or

(b) receive, at the time of a Change in Control, an amount equal to 70% of
the sum of (a) such Seller's pro rata portion of the Maximum Earnout
Payment less (b) all prior Earnout Payments paid by the Purchaser to such
Seller.  

The amount, if any, payable in respect of each of the fiscal years set
forth shall be payable, without interest, as soon as practicable after the
completion of the audit for such fiscal year, but in any event within 120
days following the end of such fiscal year.

Section 1.5 Earnout Procedures.  (a) Purchaser agrees to maintain
accounting records sufficient to allow the computation and verification of
the computation of the payments by the Purchaser to the Sellers under
Section 1.4(c) (each, an "Earnout Payment").

(b) In connection with the making of each Earnout Payment the Purchaser
shall deliver to the Sellers a copy of the audited consolidated financial
statements of Matrix Service Company, together with certain supplemental
income data of the Earnout Companies, a schedule setting forth the
computation of such payment and a copy of any other financial information
used in making such computation.  The Sellers shall have the right
following their receipt of an Earnout Payment to cause an accounting firm
chosen by the Sellers (the "Sellers' Accountants") to conduct an accounting
audit of the Earnout Companies at Sellers' expense (except as provided
below) solely for the purpose of determining the amount of such Earnout
Payment, provided that such audit shall be conducted upon reasonable
advance notice at Matrix Service Company at 10701 East Ute Street, Tulsa,
Oklahoma 74116, during normal business hours and in a manner which does not
unduly interfere with the business operations of the Earnout Companies. 
The Sellers shall give the Purchaser written notice of such an accounting
audit within twenty days following Sellers' receipt of the Earnout Payment
and the accompanying required schedule and financial information (the
"Delivery Date"). The Purchaser's computation of any Earnout Payment shall
be conclusive and binding upon the parties hereto unless, within twenty
days following the Delivery Date or, if Sellers have elected to have an
accounting audit conducted, within ten days of Sellers' receipt of the
report from Sellers' Accountants regarding the Earnout Payment, any Seller
notifies the Purchaser in writing (the "Seller's Notice") that such Seller,
either individually or on behalf of such Seller and the other Sellers
identified in the Seller's Notice (individually or collectively, as the
case may be, the "Notifying Seller"), disagrees with the Purchaser's
computation of the Earnout Payment.  The Seller's Notice shall include a
schedule setting forth the Notifying Seller's computation of the Earnout
Payment, together with a copy of any financial information, other than that
previously supplied by the Purchaser to the Sellers, used in making the
Notifying Seller's computation.  The Notifying Seller shall send a copy of
the Seller's Notice to each Seller who is not a Notifying Seller.

The Notifying Seller's computation of the Earnout Payment under this
Section 1.5(b) shall be conclusive and binding upon the parties hereto
unless, within twenty days following the Purchaser's receipt of the
Seller's Notice, the Purchaser notifies the Sellers in writing that it
disagrees with the Notifying Seller's computation of the Earnout Payment. 
If the Purchaser disagrees with the Notifying Seller's computation of the
Earnout Payment, the Purchaser and the Notifying Seller shall request a
national firm of independent certified public accountants mutually
agreeable to the Purchaser and the Notifying Seller to compute the amount
of the Earnout Payment as promptly as possible, which computation shall be
conclusive and binding upon the Purchaser and the Notifying Seller.  In the
event that the Purchaser and the Notifying Seller cannot agree on such a
national firm of independent certified public accountants, then the names
of the national accounting firms, exclusive of any such firm which is
rendering or has within the past three years rendered services to the
Purchaser or the Notifying Seller or their Affiliates, shall be selected by
lottery until one such firm is willing to compute the disputed payment for
purposes of this Agreement.  The expenses of any computation by any such
national accounting firm selected by the Purchaser and the Notifying Seller
to resolve computational disputes hereunder shall be borne half by the
Purchaser and half by the Notifying Seller.

In the event the amount of Earnout Payment to be paid by the Purchaser to
the Sellers in accordance with Section 1.4(c) is recomputed in accordance
with this Section 1.5, the adjustment to the amount of the Earnout Payment
shall be paid by the Purchaser to the Notifying Sellers within ten business
days after the date of final recomputation of such payment.  If any final
determination of the Earnout Payment shall exceed the Purchaser's original
computation of such Earnout Payment by more than ten percent (10%), then
the Earnout Payment shall also include interest on such difference from the
date upon which the original computation was delivered by the Purchaser to
the Sellers to the date of payment of the Earnout Payment, at a per annum
rate equal to the rate of the Note and the Purchaser shall reimburse the
Notifying Sellers or pay directly for the fees and expenses of Sellers'
accountants.

Sellers who are not Notifying Sellers may become Notifying Sellers by
delivering a written request to be treated as such to the Notifying Seller
and the Purchaser within ten days of receipt of the Seller's Notice given
by the Notifying Seller, whereupon such Seller shall be deemed to have been
a Notifying Seller identified in the Seller's Notice, with all rights and
obligations of a Notifying Seller provided in this Section 1.5.

Each of the Sellers hereby appoints James D. Hammond to serve as the
Notifying Seller on his or her behalf with full power and authority to make
the determinations and to take or refrain from taking the actions within
the authority of the Notifying Seller.  Each Seller shall have the right to
withdraw said appointment upon written notice to the Purchaser and each of
the other Sellers.

Section 1.6 Delivery of Certificates Representing the Shares.  At the
Closing, the Sellers shall deliver to Purchaser stock certificates
representing the Shares, duly endorsed in blank for transfer or accompanied
by appropriate stock powers duly executed in blank with all taxes, direct
or indirect, attributable to the transfer of such Shares paid or provided
for.

Section 1.7 Employment and Non-Competition Agreements.  At the Closing,
James D. Hammond, James W. Buhler, Tor F. Larson, and Douglas P. Leh shall
enter into employment and  non-competition agreements (the "Employment and
Non-Competition Agreements") with Purchaser in the form of Exhibit 1.7
hereto.

are unconditional and are in full force and effect and such notices which
have been given.

(2) Purchaser has the corporate power and authority to enter into this
Agreement and the Operative Documents to which it is a party and to carry
out its obligations hereunder and thereunder.  This Agreement has been duly
authorized, executed and delivered by Purchaser.  This Agreement

enforceable in accordance with its terms, except as may be limited by
bankruptcy, reorganization, insolvency and similar laws of general
application relating to or affecting the enforcement of rights of

Indemnitee shall promptly, and in any event within 60 days of the assertion
of any claim or the discovery of any fact upon which Indemnitee intends to
base a claim for indemnification under this Agreement ("Claim"), notify the
party or parties from whom indemnification is sought ("Indemnitor") of such
Claim.  In the event of any Claim, Indemnitor, at its option, may assume
(with legal counsel reasonably acceptable to the Indemnitee) the defense of
any claim, demand, lawsuit or other proceeding in connection with the
Indemnitee's Claim, and may assert any defense of Indemnitee or Indemnitor;
provided that Indemnitee shall have the right at its own expense to
participate jointly with Indemnitor in the defense of any claim, demand,
lawsuit or other proceeding in connection with the Indemnitee's Claim.  In
the event that Indemnitor elects to undertake the defense of any Claim
hereunder, Indemnitee shall cooperate with Indemnitor to the fullest extent
possible in regard to all matters relating to the Claim (including, without
limitation, corrective actions required by applicable law, assertion of
defenses and the determination, mitigation, negotiation and settlement of
all amounts, costs, actions, penalties, damages and the like related
thereto) so as to permit Indemnitor's management of same with regard to the
amount of Damages payable by the Indemnitor hereunder.  Neither Purchaser
nor any Seller shall be entitled to settle any Claim without the prior
written consent of the other, which consent shall not unreasonably be
withheld.

the third anniversary of the Closing, except that claims for
indemnification in respect of breaches of the representations and
warranties contained in Sections 2.1(c), (h) and (r) hereof may be made so
long as any claim may be made in respect of such matters under any
applicable statute of limitations; provided, however, that the foregoing
shall not affect any Claim made in accordance with this Article VI and in
good faith prior to the date of such expiration.

Section 6.3 Indemnification if Negligence of Indemnitee.  The
indemnification provided in this Article VI shall be applicable whether or
not negligence of the Indemnitee is alleged or proven.  The parties
acknowledge that any arbitrators appointed pursuant to Section 7.15 of this
Agreement may consider such negligence in arbitrating any disputes among
the parties.

Section 6.4 Reimbursement.  In the event that the Indemnitor shall
undertake, conduct or control the defense or settlement of any Claim and it
is later determined that such Claim was not a Claim for which the
Indemnitor is required to indemnify the Indemnitee under this Article VI,
the Indemnitee shall reimburse the Indemnitor for all its costs and
expenses with respect to such settlement or defense, including reasonable
attorneys' fees and disbursements.

for which it is entitled to indemnification under this Article VI against
any amounts payable by Purchaser to Sellers in their capacity as such,

any amounts for which they are entitled to indemnification under this
Article VI against any amounts payable by Sellers pursuant to any Operative
Documents.

Section 6.6 No Third Party Beneficiaries.  The foregoing indemnification is

the Purchaser Indemnitees and the Seller Indemnitees and shall not be
deemed extended to, or interpreted in a manner to confer any benefit, right
or cause of action upon, any other Person.

for in Section 6.1 shall be subject to the following:

(1) Sellers shall not be obligated to pay any amounts for indemnification
under Section 6.1 until the aggregate amount of Damages actually incurred

incurrence, exceeds $25,000, whereupon Sellers shall be obligated to pay
all Damages actually incurred by the Purchaser Indemnitees including such
$25,000;

and maintenance of the Collateral and Debtor's financial reporting,  and
(ii) afford any authorized representative of Secured Party with access  to
any Property owned by Debtor, during business hours and upon reasonable
notice.  For the further security of Secured Party, Secured Party shall
have a security interest in all such books and records pertaining to the
Collateral, and after any Event of Default Debtor shall turn over any such
books and records to Secured Party or to its representatives during normal
business hours at the request of Secured Party.

4.4  Location of Office and Records; Change of Name.  Debtor  shall keep
its chief place of business and chief executive office, and the  offices
where it keeps its records concerning the Accounts and the original copies
of all contracts and chattel paper that evidence or constitute  Collateral,
at the location therefor specified in Subsection 3.5 above and  shall
notify Secured Party at least thirty (30) days prior to any change  from
said location.  Debtor will not change its name, identity or corporate or
other structure to such an extent that any financing statement filed by
Secured Party in connection with this Agreement would become seriously
misleading, unless it shall have given Secured Party at least thirty (30)
days prior written notice thereof and prior to effecting any such change
taken such steps as Secured Party may deem necessary or advisable to
continue the perfection and priority of the security interest granted
pursuant hereto.

4.5  Removal of Inventory.  Debtor shall keep the Inventory at the
locations listed on Schedule II or, with the prior written consent of 
Secured Party, at such other location in a jurisdiction in which all
actions required by Subsection 4.2 shall have been taken with respect to
the Collateral as Debtor may have advised Secured Party at least thirty
(30) days prior to such removal.

4.6  Debtor Remains Liable.  Debtor shall remain liable under all
contracts or other agreements included in the Collateral to the extent set
forth therein to perform all of its duties and obligations thereunder to
the same extent as if this Agreement had not been executed.  The exercise
by Secured Party of any of the rights hereunder shall not release Debtor
from any of its duties or obligations under such contracts or agreements
included in the Collateral.  Secured Party shall not have any obligation or
liability under such contracts or agreements included in the Collateral by
reason of this Agreement, nor shall Secured Party be obligated to perform
any of the obligations or duties of Debtor thereunder or to take any action
to collect or enforce any claim for payment assigned hereunder.  Debtor
shall at its expense perform and observe all of the terms and provisions of
such contracts to be performed or observed by it to maintain such contracts
in full force and effect, enforce such contracts in accordance with their
terms, and take all such action to such ends as may from time to time be
reasonably requested by Secured Party.

4.7  Debtor to Pay Taxes.  Debtor will pay promptly when due all  property
and other taxes, assessments, and governmental charges or levies  imposed
upon and claims (including claims for labor, materials and  supplies)
against the Collateral, except to the extent (i) the validity  thereof is
being contested in good faith and by proper proceedings, (ii)  proper
reserves are being maintained in connection therewith, in accordance with
generally accepted accounting principles, consistently applied, and  (iii)
the proceedings referred to in clause (i) above could not subject  Secured
Party to any civil or criminal penalty or liability or involve any  risk of
sale, forfeiture or loss of any of the Collateral.

4.8  Transfers and Other Liens.  Debtor shall not: (a) sell,  assign, or
otherwise dispose of or grant any option with respect to any of the
Collateral (except as permitted by Subsection 7.2 of the Credit 
Agreement), or (b) create or suffer to exist any lien upon or with respect
to any of the Collateral (except as permitted by Subsection 7.1 of the
Credit Agreement).

4.9  Limitations on Modifications, Waivers or Extensions of Agreements
Giving Rise to Accounts.  Debtor will not (i) amend, modify, terminate or
waive any provision of any agreement giving rise to an Account in any
manner which could reasonably be expected to materially adversely affect
the value of such Account as Collateral, or (ii) fail to exercise promptly
and diligently each and every material right which it may have under each
agreement giving rise to an Account (other than any right of termination).
Debtor will deliver to Secured Party a copy of each material demand,
notice or document sent or received by it relating in any way to any
amendment, modification, termination or waiver of any provision of any
agreement giving rise to an Account.

4.10 Secured Party's Rights and Duties.  Debtor shall remain liable under
the Accounts to observe and perform all the conditions and obligations to
be observed and performed by it thereunder, all in accordance with and
pursuant to the terms and provisions of each Account.  Secured Party shall
not have any obligation or liability under any Accounts by reason of or
arising out of this Agreement, or the receipt by Secured  Party of any
payment relating to any Account pursuant hereto, nor shall Secured Party
be required or obligated in any manner to perform or fulfill any of the
obligations of Debtor under or pursuant to any Account or to  make any
payment, or to make any inquiry as to the nature or the sufficiency of any
payment received by Secured Party or the sufficiency of any performance by
any party under any Account or to present or file any claim, or to take
any action to collect or enforce any performance or the payment of any
amounts which have been assigned to Secured Party or to which Secured
Party may be entitled at any time or times.

4.11 Collection of Accounts and Proceeds.  Debtor shall cause all payments
from account debtors on any of the Accounts to be remitted directly to a
"lockbox" maintained with Secured Party.  Until further  notice from
Secured Party, any proceeds of Accounts remitted to the lockbox, whether
consisting of checks, notes, drafts, bills of exchange, money orders,
commercial paper of any kind whatsoever, or other documents received in
payment of any Accounts or in payment for any Inventory, shall  be
deposited by Secured Party in an operating account maintained by Matrix 
with Secured Party (subject to Secured Party's established policies on 
availability of uncollected funds).  Such proceeds when deposited shall 
continue to be collateral security for all of the Indebtedness and shall 
not constitute payment thereof until applied as hereinafter provided.  Upon
the occurrence and during the continuation of an Event of Default, Secured
Party may apply all or any part of the funds on deposit in said operating
account on account of the principal of and/or interest on any of the
Indebtedness, the order and method of any such application to be in the
sole discretion of Secured Party.  If an Event of Default shall have
occurred and be continuing, at Secured Party's request Debtor shall deliver
to Secured Party all original and other documents evidencing and relating
to the sale and delivery of Inventory or the performance of labor or
services which created the Accounts, including, but not limited to, all 
original orders, invoices, and shipping receipts.  Secured Party may, at 
any time after the occurrence and during the continuation of any Event of 
Default, notify account debtors that the Accounts have been assigned to 
Secured Party and that payment shall be made directly to Secured Party, and
Debtor will so notify such account debtors on the request of Secured Party.
 Secured Party may in its own name or in the name of others, at any time
after the occurrence and during the continuation of any Event of Default,
communicate with account debtors in order to verify with them the existence,
amount, and terms of any Accounts.

     ARTICLE V

     DEFAULT

The term "Event of Default" for all purposes of this Agreement shall mean
the occurrence of an "Event of Default" as defined in the Credit Agreement.

     ARTICLE VI

     REMEDIES

6.1  Acceleration of Indebtedness.  Upon the occurrence of any Event of
Default, Secured Party may, at its option, without notice or demand,
terminate its obligations to Debtor (including the Revolving Commitment as
defined in the Credit Agreement) and declare the Indebtedness to be
immediately due and payable, whereupon the same shall become forthwith due
and payable.

6.2  Other Remedies.  Upon the occurrence and during the continuation of
any Event of Default, Secured Party shall be entitled to exercise all
remedies available to it under the Loan Documents (as defined in the
Credit Agreement) or otherwise under applicable law, including, without
limitation, the following:

6.2.1All Legal Remedies.  Proceed to selectively and successively enforce
and exercise any and all rights and remedies which Secured Party may have
under this Agreement, any other applicable agreement or applicable law,
including, without limitation:  (i) commencing one or more actions against
Debtor and reducing the  claims of Secured Party against Debtor to judgment,
(ii) foreclosing,  realizing upon, or otherwise enforcing Secured Party's
security  interest in the Collateral, or any portion thereof, or other
enforcing  Secured Party's rights and remedies in respect of the Collateral,
through judicial action or otherwise, including all available remedies  under
the applicable provisions of the UCC, and (iii) paying or  discharging of any
claim or Lien, prior or subordinate, in respect of  or affecting the
Collateral.

6.2.2Cash Equivalent Items.  As regards any portion of the Collateral
consisting of cash equivalent items (i.e., checks, drafts or other items
convertible at face), immediately apply them  against the Indebtedness and
for this purpose Debtor agrees that such  items will be considered identical
in character to cash proceeds.

6.2.3Disposition.  Sell, lease or otherwise dispose of the Collateral at
private or public sale, in bulk or in parcels and, where permitted by law,
without having the Collateral present at the place of sale.  Unless the
Collateral is perishable or it appears that the value of the Collateral
will decline speedily or the Collateral is a type customarily sold on a
recognized market, or unless Debtor has  signed a statement (after the
occurrence of an Event of Default)  renouncing or modifying Debtor's right
to notice, Secured Party will  give Debtor reasonable notice of the time
and place of any public sale or other disposition thereof or the time
after which any private sale or other disposition thereof is to be made.
The requirements of  reasonable notice shall be met if such notice is given
to Debtor at least ten (10)days before the time of any such sale or
disposition.

6.2.4Costs and Expenses.  Recover from Debtor an amount equal to all costs,
expenses and attorney's fees incurred by Secured  Party in connection with
the exercise of the rights contained or  referred to herein, together with
interest on such sums at the default  rate applicable to the Term Note from
time to time.

6.2.5Collections.  Exercise any and all rights and remedies of Debtor
relating to the Collateral, including, but not by way of limitation, the
right to collect, demand, receive, settle, compromise, adjust or sue for
all amounts due thereon or thereunder  and the right either in Secured
Party's own name or in the name of  Debtor, to take such legal or other
action as Debtor might have taken  except for this Agreement.

6.3  Letters of Credit.  Upon the acceleration of the Indebtedness after
an Event of Default an amount equal to the aggregate stated amount of all
outstanding Letters of Credit issued by Secured Partyfor the account of
the Borrowers shall, at Secured Party's option and without demand upon or
further notice to Debtor, be deemed (as between Secured Party and the
Borrowers) to have been paid or disbursed by Secured Party under the Letters
of Credit (notwithstanding that such amounts may not in fact have been so
paid or disbursed), and a loan to the Borrowers in the amount of such Letters
of Credit to have been made and accepted, which loan shall be immediately
due and payable and shall bear interest at the post default rate provided in
the Revolving Note.  In lieu of the foregoing, at the election of Secured
Party, Debtor and/or the other Borrowers shall, upon Secured Party's demand,
deliver to Secured Party cash, or other collateral of a type satisfactory to
Secured Party, having a value, as determined by Secured Party, equal to the
aggregate outstanding Letters of Credit.  Any such collateral and/or any
amounts received by Secured Party in payment of the loan made pursuant to
this Section shall be held by Secured Party in a separate account
appropriately designated as a cash collateral account in relation to this
Agreement and the Letters of Credit and retained by Secured Party as
collateral security for the Indebtedness and each of the Letters of Credit.
Such amounts shall not be used by Secured Party to pay any amounts drawn or
paid under or pursuant to any Letter of Credit, but may be applied to
reimburse Secured Party for drawings or payments under or pursuant to Letters
 of Credit which Secured Party has paid or, if no such reimbursement is
 required, to payment of suchother Indebtedness as Secured Party shall
 determine.  At the option ofSecured Party, proceeds of sale of the
 Collateral may be used to fund thecash collateral account herein provided
 for.  Any amounts remaining in any cash collateral account established
 pursuant to this Section following payment in full of the Indebtedness,
 which amounts are not (as determined by Secured Party) to be applied to
 reimburse Secured Party for amounts actually paid by Secured Party in
 respect of a Letter of Credit, shall be returned to the Borrowers (after
 deduction of Secured Party's reasonable and necessary expenses).

6.4  Selective Enforcement.  In the event Secured Party shall elect to
selectively and successively enforce its rights and remedies in respect of
any of the Collateral, pursuant to any applicable agreements or otherwise,
such action shall not be deemed a waiver or discharge of any other right,
remedy, lien or encumbrance until such time as Secured Party shall have
been paid in full the Indebtedness.

6.5  Waiver of Default.  Secured Party may, by an instrument in writing
signed by Secured Party, waive any Event of Default which shall have
occurred and any of the consequences thereof and, in such event, Secured
Party and Debtor shall be restored to their respective former positions,
rights and obligations.  Any Event of Default so waived shall, for all
purposes of this Agreement, be deemed to have been cured and not to be
continuing, but no such waiver shall extend to any subsequent or other 
default or impair any consequence thereof.

6.6  Deposits; Setoff.  Regardless of the adequacy of any other Collateral
held by Secured Party, any deposits or other sums credited by or due from
Secured Party to Debtor shall at all times constitute collateral security
for the Indebtedness and may be set off against the Indebtedness. The
rights granted in this subsection shall be in addition to the rights of
Secured Party under any statutory banker's lien or common law right of
setoff.

6.7  Application of Payments.  During the continuance of any  Event of
Default, all payments received by Secured Party in respect of the 
Indebtedness, whether from Debtor, any of the other Borrowers, any 
guarantor, recoveries upon any portion of the Collateral or otherwise, may
be applied by Secured Party to any liabilities, obligations or indebtedness
included in the Indebtedness selected by Secured Party in its sole and
exclusive discretion.

6.8  Secured Party's Satisfaction of Debtor's Obligations.  Upon the
occurrence of any event which, but for the giving of notice or the passage
of time, would constitute an Event of Default, Secured Party may, but
shall not be obligated to, pay, satisfy or cure any liability or
obligation of Debtor arising out of or relating to this Agreement or the
Notes, upon prior notice to Debtor, and Debtor will from time to time
within ten (10) days after a request made by Secured Party, reimburse
Secured Party for all amounts expended, advanced or incurred by Secured
Party in connection with such payment, cure or satisfaction, together with
interest on such sums at the default rate applicable to the Term Note from
time to time.
