ITEM 1.  BUSINESS

FORWARD LOOKING STATEMENTS

         This report contains certain forward-looking statements which are
based on current expectations.  Actual results may differ materially.  The
forward-looking statements include those regarding cost controls and
reductions, the expected resolution of delays in billing of certain projects,
the possible impact of current and future claims against the Company based upon
negligence and other theories of liability, the integration of the recent or
ongoing acquisitions, and the possibility of the Company making acquisitions
during the next 12 to 18 months. Forward-looking statements involve numerous
risks and uncertainties that could cause actual results to differ materially,
including, but not limited to, the possibilities that the demand for the
Company's services may decline as a result of possible changes in general and
industry specific economic conditions and the effects of competitive services
and pricing; one or more current or future claims made against the Company may
result in substantial liabilities; the possibility that acquired entities may
not perform as well as expected; and such other risks and uncertainties as are
described in reports and other documents filed by the Company from time to time
with the Securities and Exchange Commission.

         In May 1997, Versar acquired a majority interest in the equity of
Science Management Corporation ("SMC") and, thereafter in October 1997,
acquired the remaining outstanding equity by merging SMC into a wholly owned
subsidiary of Versar.  During the second half of 1998, Versar discontinued the
management services and engineering, design and construction businesses
acquired from SMC as a result of poor performance and the lack of anticipated
contract backlog.  The discontinuance of the engineering, design and
construction business was a result of declining oil prices and its impact on
the process industries.  The management services business acquired from SMC
suffered from the loss of three major contracts, which constituted 75% of its
revenues. Continuing to operate SMC in its current state would have severely
impacted the viability of the entire Company.  Versar has developed a plan for
the discontinuance of SMC or the sale of the entities.  Versar has set up
appropriate reserves to shut down the existing businesses or sell them to third
parties.

         Versar is a diversified international professional services firm,
helping clients in the private and public sectors enhance their performance
while reducing costs, conserving energy, and achieving environmental
excellence.  Versar combines science, technology, and people with specialized
skills to identify problems and develop and implement solutions to assist
clients achieve their long term goals.  As part of these services, we design
facilities, systems, and equipment to improve operating performance, conserve
resources, reduce emissions and waste generation, which ultimately increase
productivity and profitability and protect worker health and safety and our
environment.

         Versar's three remaining major business areas include:  (1)
environmental services; (2) energy service; and (3) facilities infrastructure
services.  As is indicated below, certain of these business areas have
developed as a result of the integration of The Greenwood Partnership ("TGP")
into the Versar corporate group and represent a combination of TGP's services
with Versar's traditional service offerings.

         ENVIRONMENTAL SERVICES includes a full range of scientific,
engineering, and construction services to address the prevention, detection,
control, management, and cleanup of toxic substances and hazardous waste in the
environment and constituted the primary business line of Versar prior to the
acquisition of TGP. Versar emphasizes innovation in process and technology
application to achieve better results more quickly and at less cost in today's
highly competitive market.  Our goal is to help our clients build environmental
performance into each aspect of their organizational activities to enhance both
their environmental performance and improve their bottom line.  Versar achieves
this goal by helping clients become more active in preventing pollution, and
applying innovative and cost-





                                       2
<PAGE>   3
effective approaches to achieving sustainable growth while maintaining
compliance and taking corrective actions to cleanup past problems.

         Today's business challenges require viewing environmental management
as integral to a business's, operations so that informed decisions can be made
based on the economics of alternate solutions and their impact on productivity
and profitability.  These challenges are driven by:

    -    Complex and changing environmental regulations and the need for a more
         strategic approach to meet national and international environmental
         requirements in a way that allows industry to be profitable and
         competitive in a global market.

    -    Increased emphasis on managing compliance as part of operations and
         recognition that pollution prevention and waste minimization are
         necessary parts of the long-term solution to local and national
         environmental challenges.

    -    Competition for limited resources and a need for new and better
         technology to eliminate waste, reduce emissions,  and to achieve
         remediation goals more cost effectively.

Versar provides the following services to help its clients meet these
challenges:

Consulting/Engineering.  Capitalizing on Versar's combined strengths in
regulatory policy, risk assessment, information management, pollution control,
and treatment technology, which emphasize pollution prevention and waste
reduction.  Versar provides nationally recognized expert services in the area
of natural resources management and ecological assessments to assist in
establishing policies that address issues such as nonpoint source pollution,
and health and ecological impacts of industrial effluent discharge practices.
Versar also provides consulting and engineering services to industry and
government agencies in assessing alternative compliance strategies and their
impacts on our customers' operations and profits.

Versar provides turnkey services in evaluating state-of-the-art environmentally
friendly and energy efficient technology and designing and installing systems
that both enhance operating performance and reduce costs - in most cases
providing pollution prevention solutions to compliance problems.  For example,
Versar redesigned the water cycle of an industrial laundry in the Northeast so
that it would recycle and reuse process water.  This both reduced water use and
operating costs with less than a two year payback.  On another project Versar
applied an alternative technology and paint formulation for coating mass
transit vehicles eliminating the need to install a $4M fume collection system.

Outsourcing.  Versar is increasingly providing on-site and off-site support to
help our customers manage their   environmental programs.  Over the last 5
years we have been providing a full range of pollution prevention, compliance
management, cleanup, and O&M services for the Washington, D.C. Metropolitan
Transit Authority.  Versar also has a total of 19 on-site support staff at DOD
installations and industrial facilities across the country managing a wide
spectrum of customer's environmental management functions ranging from
underground storage tanks (USTs), asbestos abatement programs, air
compliance/permitting, real property transfers, and on-site hazardous material
pharmacies.

Corrective/Remedial Action.  Versar provides the full range of services in
remedial/corrective action from site investigation, remedial design, and
construction to the operation and maintenance (O&M) of remedial systems.  A
major accomplishment of the Company in FY98 was the award of a worldwide
environmental remedial action services contract (RAC) to support the Air Force
Center of Environmental Excellence.  This contract has an estimated value of
$40M over 5 years and clearly indicates recognition of Versar as a remedial
construction contractor which is where the environmental market has been moving
over the last few years.  Versar brings to its customers innovative solutions
to cleanup that are more cost effective and permanent.  For example, Versar has





                                       3
<PAGE>   4
successfully demonstrated the effectiveness of a passive reactive wall
consisting of iron fillings placed in a trench to remove halogenated organic
compounds from groundwater at Lowry Air Force Base.  This eliminated the need
to pump and treat the groundwater.  Under an existing contract to the Air Force
Armstrong Labs, Versar is separating reusable materials from bomb range
residues, used targets, and other scrap materials at Nellis Air Force Base.
Versar is brokering reusable material to aluminum processors and scrap metal
smelters and is saving the government an estimated $3.5M in offsets to the
total cleanup cost of $8.6M.  Versar is also applying innovative approaches
that include creative financing, and stop loss insurance to cleanup
opportunities in the redevelopment of industrial properties under EPA and
States' Brownfields programs.  For example, Versar is in the process of
redeveloping a Petroleum Refinery in the Western U.S. where we have assisted
the customer in creatively financing of the project through previous insurers
of the property.  Versar primarily focuses on the enhancement of assets in the
cleanup of sites and the redevelopment of industrial facilities and commercial
properties.  Versar has established alliances with real estate and investment
firms to help clients bring new life to other abandoned, contaminated sites in
prime real estate locations.

    Versar's Environmental Services address management, compliance, and
remedial/corrective needs of clients in a wide range of technical areas
including:

    -    Environmental Policy
    -    Air Quality
    -    Water/Groundwater Quality
    -    Waste Management
    -    Risk Assessment
    -    Ecological Studies
    -    Technology Evaluations
    -    Natural Resources Management
    -    Industrial Hygiene
    -    Asbestos and Lead Paint
    -    Tank Management

    Personal Protection Equipment (PPE)/ChemDemilitarization.  A specialty area
for the Company is its Chemical Surety Laboratory and its related expertise in
personal protection equipment. Versar's support to the U.S. Army's Chemical
Weapons Demilitarization program is an important business area for Versar.
Versar's subsidiary, GEOMET Technologies, Inc., is involved in the disposal of
residual chemical weapons material at sites throughout the United States.
GEOMET's program, now in its fourth year, includes outfitting and operating the
mobile laboratory, which will support the disposal operations, design of air
monitoring and warning systems, specification of the PPE to be used, and other
assignments dealing with environmental compliance, development of operational
procedures, and program management.  GEOMET is also in the business of
developing and testing PPE.  Current projects include development of two PPE
ensembles for use in the depots where chemical weapons are stockpiled and in
activities where exposure to chemical agents is likely, such as laboratory work
and emergency response.  The ensembles include a protective suit, clean air
source, radio communications, and a personal ice cooling system (PICS) for the
worker.  In July 1998, GEOMET was awarded a $27.5M contract for the production
and fielding of the Army's Self-Contained Toxic Environment Protection Outfit
(STEPO) System at 73 installations through the year 2002.  The system will be
used to recover, render safe, store and dispose of unexploded chemical and
biological weapons.  GEOMET is also a commercial supplier to remedial action
contractors and emergency responders of PPE specially qualified for chemical
protection.  Driven in part by the sarin nerve gas attack on the Tokyo subway
in 1995, Versar has significantly expanded this division's offering its
services to local, state, United States, and foreign governments in support of
counter-terrorism.  Management believes the opportunities for commercial
application of its products and services will continue to grow in this area.

    ENERGY CONSERVATION SERVICES.  With the acquisition of The Greenwood
Partnership ("Greenwood" or "TGP"), Versar now includes energy conservation
services as part of its core business.  This not only helps diversify the





                                       4
<PAGE>   5
Company's business it provides a new entry to existing and new customers in an
emerging growth market. GEOMET Technologies Inc., Versar's subsidiary, has for
many years provided demand side management support to utilities in the
identification and implementation of efforts to reduce energy consumption.
GEOMET has provided energy auditing and energy conservation services for a
variety of clients.  The Greenwood Partnership brings to Versar, engineering,
design, and construction management expertise in the upgrade of plant
infrastructure to reduce energy consumption.

    Versar, through TGP, currently has alliances with three major utilities who
are marketing and experienced in Energy Services Performance Contracts (ESPC)
for the government and industry. These alliances include Duke Energy
(DukeSolutions Inc.), Virginia Power and Light (Evantage Co.), and Carolina P&L
(Strategic Resources Services).  Potential fees on these contracts are based on
energy savings that can be achieved. Versar's utility partners make the
required investment to upgrade each facility while Versar is reimbursed on the
basis of a negotiated fixed fee.

    Major utilities in the ESPC market are driven by the opportunity to develop
alliances with government and industry customers as deregulation of this
industry occurs in the U.S.  The current market in the Federal sector is driven
by Executive Order 12902 that requires government facilities to reduce energy
consumption by 30% by 2005.  However, it is generally believed that an even
larger market for energy conservation services exists in the private and
commercial sectors.

    FACILITY INFRASTRUCTURE SERVICES include a full range of architectural and
engineering services in industrial/commercial facilities and supporting central
mechanical and electrical utilities and building systems.  It also includes O&M
outsourcing services.

    Facility Infrastructure Services is the core business of TGP which has been
integrated with Versar's engineering capabilities of Versar's core
environmental engineering services.  This combined capability allows the
Company to bring state-of-the-art technology to its customers in reducing
waste, minimizing emissions, and in recovering and reusing resources to achieve
a sustainable business environment.  For example, TGP recently designed a
microchip manufacturing facility deploying state-of-the-art material handling,
waste treatment, and utility infrastructure support technology.

    Key industrial sectors that the Company serves include the pharmaceuticals,
electronics, biotechnology, food processing, paper products, film, plastics and
fiber industries.  Services include architectural design, site development, as
well as the design, construction or design-build of plant facility, and
supporting utility, material handling, and waste management systems.

    Versar/TGP provides design expertise in plant structures and associated
utilities, fuel handling, chemical treatment, distribution, piping systems
instrumentation and controls, substations and electric power distribution
systems.  Systems are designed to optimize performance, environmental
compliance, safety, energy use, and utilization of space.  Economic evaluations
of alternative designs, fuels, and operating parameters are conducted to
produce bottom line savings for our customers throughout the life cycle of
heating, cooling and electric power systems.

    Services are performed for a wide range of corporate, industrial,
commercial, state, Federal, health care and educating customers.  Specific
services include:

    -    Retrofit and Renovations
    -    Energy Management Studies and Audits
    -    Fire Protection
    -    Life Safety
    -    Performance Contracting





                                       5

    -    Life-Cycle Analysis
    -    Heating and Cooling Distribution Systems
    -    Electrical Power and Lighting
    -    Building HVAC Systems

    Versar is offering to take over the operation and maintenance of utility
infrastructure systems of its customers on a contract services basis.


MARKETS

    Versar's markets are evolving in response to its clients' changing needs,
and market opportunities are being driven by the availability of technology
aimed at enhancing operating performance and profitability.  Versar has
diversified its business over the last few years, primarily through the
acquisition of TGP, with a much greater emphasis on  (1) environmental services
which help the bottom line such as P2 initiatives with short paybacks and
redevelopment of industry properties and conversion of military bases for
alternative productive uses, (2) the emerging energy conservation services
markets with TGP providing Versar with alliances and core capabilities to enter
this new market, and (3) facilities infrastructure services to respond to our
clients' increasing need to upgrade plant and equipment to improve their
operating performance and to outsource non-core functions.

Versar is participating in a number of growth markets.  These include:

    -    Industry's continued focus on productivity improvement with increased
         need for services in upgrading plant and utility infrastructure.

    -    Deregulation of the energy industry presents opportunities for Versar
         through TGP in energy conservation projects.

    -    Government /commercial interest in expanding capability to respond to
         potential terrorism worldwide will provide continued growth
         opportunities for Versar (GEOMET) services in personnel protection
         equipment.

    -    Brownsfield legislation and tax incentives will provide opportunities
         for growth of Versar's environmental cleanup services.

    -    Continued pressure to reduce environmental management cost will
         provide opportunities for Versar to grow its business in pollution
         prevention, and outsourcing services.

    Versar's current client base is well balanced with 44 percent
industrial/commercial and 56 percent government.  Versar also provides a wide
range of services to the financial/real estate/insurance business sector,
transportation and communications sector, services industries and others.

    The U.S. Department of Defense (DOD) is Versar's largest government client,
making up 33 percent of its business base. DOD is going through many of the
same issues as are faced in private industry with restructuring and cost
reduction in response to increasing budget limitations.  DOD also has an
aggressive environmental program to cleanup, realign, and close bases worldwide
as it continues to restructure to a smaller force.  The major focus over the
next few years will be the to reduce its infrastructure.  Versar is a major
support contractor to DOD, offering the same range of services as in the
private sector.  The U.S. Environmental Protection Agency (EPA) makes up 7
percent of Versar's business and is growing in new areas such as water quality,
risk assessment, and natural resources management.  Versar thus maintains
extensive knowledge of regulatory trends and their impacts.  Other Federal
clients make up 5 percent of our business and include NASA, the Departments of
Energy and the Interior, Federal Housing Authority, and Intelligence Agencies.
State and local governments make up 11 percent of Versar's business.





                                       6

COMPETITION

    Versar traditionally has faced substantial competition in each market in
which it operates and expects to continue to face substantial competition as it
diversifies its business.  Many times, its competitors are larger and have
greater financial resources.  Versar has historically competed primarily on its
scientific, technological,  and engineering expertise as well as costs.  As
Versar's business mix shifts more toward providing turnkey infrastructure and
resources management support services, Versar will compete with more facility
O&M and engineering/construction contractors on projects that lend themselves
more to innovation in approach, technology application, and project financing
- -- areas where Versar's senior management are skilled in packaging responses to
new and different opportunities.  In essence, the market is changing rapidly,
and Versar is taking advantage of these changes to position itself for
substantial growth in new and emerging markets by providing much needed
infrastructure support to industry and government as we enter the 21st century.
However, no assurances can be given that Versar will be able to achieve such
growth or successfully compete in such new areas.

BACKLOG

    As of June 30, 1998, total backlog for Versar, including unfunded tasks and
orders, was approximately $301 million, as compared to approximately $340
million as of June 30, 1997.  Funded backlog for Versar was approximately $30
million, a decrease of 27 percent compared to approximately $41 million as of
June 30, 1997, as a result of the discontinuance of the operations of SMC,
which made up approximately $15 million of the fiscal year 1997 backlog.
Funded backlog is the incremental funding authorization of contracts and task
orders based on firm contractual obligations.  Unfunded backlog includes
contracts and contract vehicles, including option periods, in which specific
work tasks and funding have not been authorized and for which Versar and the
client are contractually obligated to perform. Funded backlog amounts have
historically resulted in revenues; however, no assurance can be given that all
amounts included in funded backlog will ultimately be realized as revenue.

EMPLOYEES

    At June 30, 1998, Versar had approximately 441 full-time employees, of
which approximately 394 were engineers, scientists, and other professionals.
Seventy-five percent of the Company's professional employees have a bachelors
degree, 30% have a masters degree, and 4% have doctorate degrees.

ITEM 2.  PROPERTIES

         The Company's executive office is located in a building in
Springfield, Virginia, a suburb of Washington, D.C.  In June 1995, Versar
leased 73,371 square feet in two buildings from Sarnia Corporation.  In October
1997, Versar reduced this leased space to 68,414 square feet.  The rent is
subject to a 4% escalation per year.  Both lease streams are subject to
adjustment on June 1, 1999 and 2004.  In these years, the lease streams will be
adjusted to the current fair value.  This value will set the base rate of the
lease streams in the year of adjustment.  The adjusted lease stream is subject
to the contracted escalation in future years.

         As of September 1, 1998, the Company had under lease an aggregate of
approximately 209,000 square feet of office and laboratory space in the
following locations:  Springfield, Lynchburg, Richmond, and Williamsburg, VA;
Tempe, AZ; Alameda and Fair Oaks, CA; Northglenn, CO; Miami, FL; Lombard, IL;
Burlington, MA; Hopkins, MN; Columbia, Gaithersburg and Germantown, MD;
Bristol, PA; San Antonio, TX; and American Fork, UT.  These leases are
generally for terms of five years or less.

         Versar believes that its facilities are suitable and adequate for its
current and foreseeable operational and administrative needs.

ITEM 3.  LEGAL PROCEEDINGS

         In December 1994, SMC Environmental Services Group, Inc., an indirect
subsidiary of Versar, a former employee of SMC, and two other entities were
sued by Edward A. Long, an employee of an operator of a municipal waste
transfer station.  Mr. Long alleges that in October 1992, while transferring
leachate from a holding tank to a tanker truck, he blacked-out and suffered
serious personal injuries.  The lawsuit, entitled Edward A. Long v. Lehigh
Valley Recycling, Inc. et al., No. 94-20222, was filed in the Court of Common
Pleas of Montgomery County, Pennsylvania, Civil Division.  SMC Environmental
and its employee, who had been retained by the owner of the municipal waste
transfer station to help finalize a permit application with the Pennsylvania
Department of Environmental Protection in 1988, filed an answer denying the
allegations.  The parties have undertaken certain discovery which remains
ongoing.  Because this claim arose prior to the acquisition of SMC and its
subsidiaries by Versar, the Company is reviewing the insurance coverage
available to the Company.  Based upon consultation with outside counsel,
management does not believe the ultimate outcome of this lawsuit will have a
material impact on Versar's consolidated financial condition or its results of
operations.

         Versar and its subsidiaries are parties to various other legal actions
arising in the normal course of business.  The Company believes that an
ultimate unfavorable resolution of these other legal actions will not have a
material adverse effect on its consolidated financial condition and results of
operations.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

         No matters were submitted to a vote of the Company's security holders
during the last quarter of fiscal year 1998.

         Certain amounts in fiscal year 1994 have been reclassified to reflect
Versar Laboratories, Inc. and Gammaflux, Inc. as discontinued operations for
comparative purposes.  In addition, Versar has included the results of
operations and financial position of Sarnia through January 1, 1996.  Sarnia
was spun-off to stockholders in fiscal year 1994, but continued to be reflected
in Versar's financial statements due to the guarantee of all of Sarnia's debt
by Versar.  After the completion of Sarnia's refinancing of its debt in January
1996, Versar's guarantee was reduced from $12.4 million to $1.5 million and the
divestiture was considered complete for accounting purposes. Certain amounts in
fiscal year 1997 have been reclassified to reflect the two segments of SMC,
engineering, design and construction services and management services, as 
discontinued operations for comparative purposes.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS

         This report contains certain forward-looking statements which are
based on current expectations.  Actual results may differ materially.  The
forward-looking statements include those regarding cost controls and
reductions, the expected resolution of delays in billing of certain projects,
the possible impact of current and future claims against the Company based upon
negligence and other theories of liability, the integration of the recent or
ongoing acquisitions, and the possibility of the Company making acquisitions
during the next 12 to 18 months. Forward-looking statements involve numerous
risks and uncertainties that could cause actual results to differ materially,
including, but not limited to, the possibilities that the demand for the
Company's services may decline as a result of possible changes in general and
industry specific economic conditions and the effects of competitive services
and pricing; one or more current or future claims made against the Company may
result in substantial liabilities; the possibility that acquired entities may
not perform as well as expected; and such other risks and uncertainties as are
described in reports and other documents filed by the Company from time to time
with the Securities and Exchange Commission.

         Versar's results of operations include the financial results that are
part of the continuing operations of the Company.  In May 1997, Versar acquired
a majority equity interest in SMC and, thereafter in October 1997, the
remaining outstanding equity.  Following its acquisition, SMC's engineering,
design and construction services and management services segments failed to 
perform in accordance with the expectations of Versar's management due to
significant business shortfalls in these segments.  In September 1998, Versar's
Board of Directors authorized management to discontinue the operations of
Science Management Corporation constituting the engineering, design and
construction services and management services segments of Versar.  Therefore, 
results of operations of SMC's two segments have been netted together and 
presented on one line, as a loss from discontinued operations. The following 
discussion relates to continuing operations only, unless specifically noted.

         Versar's gross revenues from continuing operations for fiscal year
1998 totaled $50,420,000, or $5,485,000 (12.2%) above fiscal year 1997 gross
revenue of $44,935,000.  Gross revenue for fiscal year 1997 was $652,000
(1.5%) above that reported in 1996.  The increase in Versar's gross revenue in
fiscal year 1998 was due to five months of revenue from the acquisition of the
Greenwood Partnership ("TGP") of $2,300,000 and the remaining balance of the
increase was with Versar's base business.  As reflected in the table on page
14, government revenue represented 56.0% of the total revenue in 1998, compared
to 64.0% in 1997 and 66.0% in 1996.  The reduction is attributable to the
addition of TGP and additional Versar commercial revenues.

         Purchased services and materials for fiscal year 1998 totaled
$15,525,000 or $2,286,000 (17.3%) higher than fiscal year 1997 purchased
services.  Purchased services for fiscal year 1997 were $875,000 (7.1%) higher
than reported in fiscal year 1996. The increase in 1998 is due to subcontracted
efforts on a remediation project in the Company's Northeast operation.

         Net service revenue is derived by deducting the costs of purchased
services from gross revenue.  Versar considers it appropriate to analyze
operating margins and other ratios in relation to net service revenue because
such revenues reflect the actual work performed by the Company.

         Direct costs of services and overhead include the cost to Versar of
direct and overhead staff, including recoverable overhead costs and unallowable
costs that are directly attributable to overhead.  The percentage of these
costs to net service revenue increased to 84.3% in 1998 compared to 80.1% in
1997 and 81.4% in 1996.  The increase is due to operating losses of EIMS
software business and ValuAdd municipal operations of $422,000, lower labor
multipliers in TGP and lower margins on existing projects than Versar's base
business.

         Selling, general and administrative expenses approximated 13.7% of net
service revenue in 1998, compared to 16.0% in 1997 and 15.5% in 1996.  The
decrease in fiscal years 1998 and 1997 are attributable to the higher net
service revenue, while the corporate costs for the Company were reduced.

         Other income includes the costs and revenues that are not directly
attributable to contracts.  In 1998, the Company had no other income or costs
compared to $42,000 and $28,000 of income in fiscal years 1997 and 1996
associated with a non-compete agreement from the sale of its majority-owned
subsidiary Gammaflux, Inc.

         In fiscal year 1998, the Company recorded a special charge of $330,000
to write off of receivables and write-off of goodwill for the ValuAdd
operations.  The Company's decision to shut down the ValuAdd operations is a
result of significant business shortfalls in the ValuAdd operations.

         Operating income for 1998 was $378,000, a decrease of $888,000 over
fiscal year 1997.  The decrease is primarily due to the special charge as
mentioned above and the $422,000 of operating losses on EIMS and ValuAdd
operations, which were closed in fiscal year 1998.

         Interest expense during 1998 was $251,000, an increase of $154,000
from 1997.  The increase is due to the cost of financing for the acquisition of
SMC of approximately $150,000.

         Versar's income tax benefit for fiscal year 1998 was $149,000 compared
to a tax expense of $60,000 in fiscal year 1997.  Due to the losses in the
current fiscal year and the non-deductible goodwill from SMC, the Company
increased its valuation on deferred tax assets until the earnings improve to
ensure the utilization of the tax assets.  Refer to Note I of the Notes to
Financial Statements.

         In fiscal year 1998, the Company recorded a loss from discontinued
operations for the two segments acquired from SMC of $8,829,000 net of $90,000
tax benefit including the write-off of goodwill associated with its acquisition
of $5,064,000 and operating losses for a total of $5,776,000 (net of tax) and
accrued reserves of $3,053,000 to finalize the disposition of SMC.  As part of
the accrued reserves the Company reserved approximately $1,700,000 for
operating losses in the phase out of the two segments. (Refer to Note C and I
of the Notes to Financial Statements for further information on the
discontinuance of the engineering, design and construction services and
management services segments of SMC and the related tax impact to the Company.)

         In summary, Versar's net loss was $8,553,000 in fiscal year 1998,
compared to net income of $1,256,000 in fiscal year 1997 and net income of
$992,000 in fiscal year 1996.

LIQUIDITY AND CAPITAL RESOURCES

         The Company's operating activities utilized $1,667,000 of cash in 1998
primarily for working capital requirements at SMC and delayed receipt of
receivables.

         The Company utilized short-term bank financing to supplement its
ability to meet day-to-day operating cash requirements.  At June 30, 1998, the
Company had $4,720,000 of working capital, compared to $9,140,000 in 1997.
Working capital decreased by 48% primarily due to poor operating performance of
SMC, working capital requirements of SMC and the acquisition of The Greenwood
Partnership.

         In April 1997, the Company moved its line of credit facility to
NationsBank, N.A.  The new line of credit of $5,000,000 is restricted to the
borrowing base of qualifying receivables less the balance of $1,200,000 reserve
for a guarantee of debt of Sarnia and outstanding acquisition loan balances
(approximately $1,437,500 at June 30, 1998).  Borrowings on the line of credit
are at the lower of the 30 day London Interbank Offered Rate ("LIBOR") plus 250
or the prime rate (8.16% at June 30, 1998).  A fee of 1/4% on the unused
portion of the line of credit is also charged.  The line is guaranteed by the
Company and each of the Company's wholly owned subsidiaries individually and is
collectively secured by accounts receivable, equipment and intangibles, plus
all insurance policies on property constituting collateral.  Unused borrowing
availability at June 30, 1998 was approximately $1,336,000.  Advances on the
line are due on November 30, 1998.  The Company's covenants were modified as of
June 30, 1998, due to the discontinuance of the two segments acquired from SMC.
Management believes that cash generated by operations and borrowings available
under the line of credit and extension of the line will be adequate to meet the
working capital needs for fiscal year 1999.

         As previously reported, Versar has guaranteed a five year term loan
with an original balance of $1,500,000 and a current balance of $1,200,000 for
Sarnia.  Versar's reserve against the loan as of June 30, 1998 is $1,200,000.
As the term loan is repaid, the reserve will be reduced and added to Versar's
equity. Starting in fiscal year 1998, principal payments of $300,000 are due
each year and will be added back to Versar's equity as they are paid by Sarnia.

ACQUISITION OF THE GREENWOOD PARTNERSHIP

         On January 30, 1998, Versar completed the acquisition of The Greenwood
Partnership, P.C.  As a part of the acquisition, the Company increased its
current line of credit by $2,000,000 to $5,000,000 and retired existing debt of
Greenwood of approximately $672,000, paid $300,000 in cash, recorded additional
notes payable to Greenwood stockholders of $450,000 payable over 4 years, and
issued 228,572 shares of common stock. The transaction was accounted for as a
purchase of assets and goodwill recorded as part of the transaction was
approximately $1.1 million.  The assets of Greenwood are now included as
collateral under the Company's line of credit.

IMPACT OF INFLATION

         Versar seeks to protect itself from the effects of inflation.  The
majority of contracts the Company performs are for a period of a year or less
or are cost plus fixed-fee type contracts and, accordingly, are less
susceptible to the effects of inflation.  Multi-year contracts provide for
projected increases in labor and other costs.

BUSINESS SEGMENT

         In June 1997, the Financial Accounting Standard Board issued Statement
of Financial Accounting Standard No. 131 "Disclosures about Segments of an
Enterprise and Related Information" (SFAS No. 131).  SFAS No. 131 becomes
effective in Versar's fiscal year 1999.  SFAS No. 131 requires disclosure of
operating segments of the Company so that the reader can better understand and
assess the business enterprise performance taken as a whole. Versar currently
has three business segments:  environmental services, energy conservation
services, and facility infrastructure services.  Currently, the energy
conservation and facility infrastructure services segments do not meet the
reporting requirements under those required by SFAS No. 131 or SFAS No. 14. 
During fiscal year 1999, the growth in these segments may require the Company
to provide financial disclosure as required under SFAS No. 131.

YEAR 2000

         Certain computer programs have been written using two digits rather
than four to define the applicable year, which could result in the computer
recognizing a date using "00" as the year 1900 rather than the year 2000.
This, in turn, could result in major system failures and in miscalculations,
and is generally referred to as the "Year 2000" problem.  On August 4, 1998,
the Company's Board of Directors adopted a comprehensive Strategy for Achieving
Year 2000 Compliance program for Versar and its subsidiaries.  Subsequently,
management has begun to implement the eight step program to identify both
internally and externally the extent of any Year 2000 problem, the cost to the
Company to mitigate any Year 2000 effects and identify any significant client
or subcontractor compliance issues. Among other things, Versar is in the
process of evaluating the different options that are available to upgrade the
Company's existing data, business processing and financial reporting software
applications to be Year 2000 compliant.  Presently, Versar does not believe
that Year 2000 compliance will result in any material investments, nor does
Versar have any information that the Year 2000 problem will have material
adverse effects on the business operations or financial performance of Versar.
In addition, Versar is not aware of any Year 2000 problems of its customers,
suppliers or network affiliates that will have a material adverse effect on the
business, operations or financial performance of Versar. However, the
implementation of our in-house and outside survey has just begun, so there can
be no assurance that the year 2000 problem will not adversely affect Versar and
its business.  It is expected to cost between $100,000 to $300,000.  Versar
expects that the Company will be in Year 2000 compliance by June 30, 1999.

                    Report of Independent Public Accountants



To the Board of Directors and Stockholders of Versar, Inc.:

We have audited the accompanying consolidated balance sheets of Versar, Inc.
and its subsidiaries (a Delaware corporation) as of June 30, 1998 and 1997, and
the related consolidated statements of operations, changes in stockholders'
equity, and cash flows for each of the three years in the period ended June 30,
1998. These financial statements are the responsibility of the Company's
management.  Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Versar, Inc. and
its subsidiaries as of June 30, 1998 and 1997, and the results of their
operations and their cash flows for each of the three years in the period ended
June 30, 1998, in conformity with generally accepted accounting principles.

Our audit was made for the purpose of forming an opinion on the basic financial
statements taken as a whole.  The schedule listed in the index of financial
statements is presented for purposes of complying with the Securities and
Exchange Commission's rules and is not part of the basic financial statements.
This schedule has been subjected to the auditing procedures applied in the
audit of the basic financial statements and, in our opinion, fairly states in
all material respects the financial data required to be set forth therein in
relation to the basic financial statements taken as a whole.

                          VERSAR, INC. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE A  SIGNIFICANT ACCOUNTING POLICIES

         Principles of consolidation: The accompanying consolidated financial
statements include the accounts of Versar, Inc. and its majority-owned
subsidiaries ("Versar" or the "Company"). All significant intercompany balances
and transactions have been eliminated in consolidation. The results of
operations of Sarnia Corporation ("Sarnia") were included in the Company's
financial statements through January 1, 1996. In September 1998, the Company
decided to discontinue its management services and engineering, design and
construction services businesses which are classified as discontinued
operations. Both of these businesses came from the acquisition of SMC in May
1997 (see Note B). The Company's remaining business segments are environmental
services, energy conservation services and facility infrastructure services. The
energy conservation and facility infrastructure segments are collectively less
than 10% of consolidated revenues, operating profit and identifiable assets and
therefore separate segment reporting is not required under Statement of
Financial Accounting Standards (SFAS) No. 14 "Financial Reporting for Segments
of a Business Enterprise". Both segments are expected to grow and may become
separate reportable segments in fiscal year 1999.

         Accounting estimates: The preparation of financial statements in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results may differ from those estimates.

         Contract accounting: Contracts in process are stated at the lower of
actual cost incurred plus accrued profits or net estimated realizable value of
incurred costs, reduced by progress billings. The Company records income from
major fixed-price contracts, extending over more than one accounting period,
using the percentage-of-completion method. During performance of such
contracts, estimated final contract prices and costs are periodically reviewed
and revisions are made as required. The effects of these revisions are included
in the periods in which the revisions are made. On cost-plus-fee contracts,
revenue is recognized to the extent of costs incurred plus a proportionate
amount of fee earned, and on time-and-material contracts, revenue is recognized
to the extent of billable rates times hours delivered plus material and other
reimbursable costs incurred. Losses on contracts are recognized when they become
known. Disputes arise in the normal course of the Company's business on projects
where the Company is contesting with customers for collection of funds because
of events such as delays, changes in contract specifications and questions of
cost allowability or collectibility. Such disputes, whether claims or unapproved
change orders in the process of negotiation, are recorded at the lesser of their
estimated net realizable value or actual costs incurred and only when
realization is probable and can be reliably estimated. Claims against the
Company are recognized where loss is considered probable and reasonably
determinable in amount.

         It is the Company's policy to provide reserves for the collectibility
of accounts receivable when it is determined that it is probable that the
Company will not collect all amounts due and the amount of reserve requirements
can be reasonably estimated.

         Depreciation and amortization: Depreciation and amortization are
computed on a straight-line basis over the estimated useful lives of the assets.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)



         Intangible assets: On April 29, 1996, Versar purchased for 30,000
common shares the assets of ValuAdd. The purchase resulted in the Company
recording goodwill of $97,500, which was being amortized over a five year
period. In fiscal year 1998, the Company recorded a special charge of $330,000
to write off of receivables and write off of goodwill for the ValuAdd
operations. The Company's decision to shut down the ValuAdd operations is a
result of significant business shortfalls in the ValuAdd operations. The
remaining balance of approximately $55,000 was written off as of June 30, 1998
as the Company determined that the goodwill was impaired. On May 2, 1997, Versar
acquired 53.5% of the outstanding common stock and all outstanding preferred
stock of Science Management Corporation ("SMC") for cash. Versar had selected a
period of 15 years for amortization of the goodwill, which was determined to be
reasonable based on the mature businesses of SMC.

         On October 22, 1997, the shareholders of SMC approved the Agreement and
Plan of Merger between Versar and SMC, and SMC was merged into a wholly-owned
subsidiary of Versar effective October 23, 1997. In connection with the merger,
Versar issued approximately 533,433 shares of Versar's common stock to SMC
stockholders and SMC became a wholly-owned subsidiary of Versar. The issuance of
the 533,433 shares and transaction costs increased goodwill and equity of Versar
during the second quarter of fiscal year 1998 by approximately $2,898,000.

         In accordance with SFAS No. 121, in the fourth quarter of fiscal year 
1998, the Company determined that the projected future cash flows over the 
next 14 years, based on current information, will not be sufficient to offset 
the goodwill amortization related to the SMC acquisition. The Company further
determined that the goodwill was fully impaired and, accordingly, wrote off the
entire balance of $5,064,000 of goodwill resulting from the SMC acquisition.

         On January 30, 1998, Versar completed the acquisition of The Greenwood
Partnership, P.C. ("Greenwood" or "TGP"). As a part of the acquisition, the
Company increased its current line of credit by $2,000,000 and retired existing
debt of Greenwood of approximately $672,000, paid $300,000 in cash, recorded
additional notes payable to Greenwood stockholders of $450,000 payable over 4
years, and issued 228,572 shares of common stock. The transaction was accounted
for as a purchase. Goodwill recorded as part of the transaction was
approximately $1.1 million. Versar is amortizing the goodwill related to the
acquisition over 15 years, which was determined to be reasonable based on the
mature business of Greenwood. The assets of Greenwood are now included as
collateral as part of the Company's line of credit.

         Direct costs of services and overhead: These expenses represent the
cost to Versar of direct and overhead staff, including recoverable overhead
costs and unallowable costs that are directly attributable to overhead.

         Net (loss) income per share: The Company adopted Statement of Financial
Accounting Standards (SFAS) No. 128 "Earnings Per Share," which requires
companies to present basic earnings per share and diluted earnings per share.
The Standard requires additional informational disclosures along with the
restatement of earnings per share for all prior periods reported.

         Income taxes: The Company follows Statement of Financial Accounting
Standards No. 109, "Accounting for Income Taxes" (SFAS No. 109). The Standard
requires the recognition of deferred tax liabilities and assets for the expected
future tax consequences of temporary differences between the carrying amounts
and the tax bases of other assets and liabilities.

         Deferred compensation: The Company permitted employees to defer a
portion of their compensation, during fiscal years 1988 through 1991, providing
for future annual payments, including interest. Interest is accrued on a monthly
basis at the amount stated in each employee's agreement. The Company has
liabilities for deferred compensation of $1,026,868 and $990,000 at June 30,
1998 and 1997, respectively. Versar purchased key-man life insurance policies to
fund the amounts due under the deferred compensation agreements. The cash
surrender value of the policies, net of loans, was $194,000 and $215,000 at June
30, 1998 and 1997, respectively.

         Cash and Cash Equivalents: All investments with an original maturity of
three months or less are considered to be cash equivalents.

         New Accounting Pronouncements: In June 1997, the Financial Accounting
Standard Board issued Statement of Financial Accounting Standard No. 131
"Disclosures about Segments of an Enterprise and Related Information" (SFAS
131). SFAS No. 131 becomes effective in Versar's fiscal year 1999. SFAS No. 
131 requires disclosure of operating segments of the Company so that the reader
can better understand and assess the business enterprise performance taken as a
whole. Versar currently has three business segments: environmental services,
energy conservation services, and facility infrastructure services. Currently,
the energy conservation and facility infrastructure services segments do not
meet the reporting requirements under those required by SFAS No. 131 or SFAS
No. 14. During fiscal year 1999, the growth in these segments may require the
Company to provide financial disclosure as required under SFAS No. 131.

NOTE B  ACQUISITIONS

         On May 2, 1997, Versar acquired 53.5% of the outstanding common stock
and all outstanding preferred stock of SMC for $2,870,000 in cash. The
acquisition was financed by a three year $2,000,000 term note at a prime rate of
interest plus 1/2% (9% at June 30, 1998) from NationsBank, N.A. The remaining
portion of $870,000 was paid with current working capital. This transaction was
accounted for under the purchase method of accounting.

         On October 22, 1997, the shareholders of SMC approved the Agreement and
Plan of Merger between Versar and SMC, and SMC was merged into a wholly-owned
subsidiary of Versar effective October 23, 1997. In connection with the merger,
Versar issued approximately 533,433 shares of Versar's common stock to SMC
stockholders other than Versar and SMC became a wholly-owned subsidiary of
Versar. The issuance of the 533,433 shares increased goodwill and equity of
Versar during the second quarter of fiscal year 1998 by $2,898,000. SMC
represented the engineering, design, and construction services and management
services segments of the company in fiscal year 1997. The entire balance of the
goodwill was written off in fiscal year 1998 as the SMC businesses are
presented as discontinued operations in fiscal year 1998.

         On January 30, 1998, Versar completed the acquisition of The Greenwood
Partnership, P.C. As a part of the acquisition, the Company increased its
current line of credit by $2,000,000 and retired existing debt of Greenwood of
approximately $672,000, paid $300,000 in cash, recorded an additional note
payable to Greenwood stockholders of $450,000 payable over 4 years, and issued
228,572 shares of common stock. The transaction was accounted for as a purchase
of assets and goodwill recorded as part of the transaction was approximately
$1.1 million. The assets of Greenwood are now included as collateral as part of
the Company's line of credit. The Greenwood operation became part of Versar's
energy conservation segment.

NOTE C  DISCONTINUED OPERATIONS

         As a result of poor performance following its acquisition of SMC, the
Company determined to discontinue operations of its management services and
engineering, design and construction services segments (acquired from SMC),
which provides services to the commercial and the petrochemical industries. 
The engineering, design and construction services segment was severely impacted
by the recent downturn in the petrochemical industry and the winding down of a
$20 million construction project, which reduced their sales volume by over 80%.
Such a downturn could not be reasonably anticipated as several pending projects
were put on hold or cancelled because the reduced oil prices did not make it
economically feasible for the projects. The management services segment of SMC
also suffered from loss of three large contracts which represented 75% of the
sales volume. The Company is pursuing sale of these two businesses and expects
that such sales will occur within fiscal year 1999. The Company has identified
potential buyers, but, if a sale does not occur within a reasonable period it
is likely that a shut down will be required. A shut down would

not result in further material loss to the Company. SMC's sales for fiscal year
1998 were $34,769,000 and $3,582,000 for the two months of fiscal year 1997.

         In conjunction with the decision for discontinuance of these
businesses, the Company recorded a loss from discontinued operations of
$8,829,000 net of $90,000 tax benefit due to the write-off of goodwill
associated with its acquisition and operating losses of $5,776,000 (net of tax)
and accrued reserves of $3,053,000 to finalize the disposition. As part of the 
accrued reserves, the Company reserved approximately $1,700,000 for operating 
losses in the period prior to the sale or shut down.

         Current assets of discontinued operations consist primarily of accounts
receivable. Long term liabilities consist primarily of previous SMC bankruptcy
obligations prior to 1996. (see Note I concerning the tax effect of the
discontinuance.)

         Summarized financial results of the discontinued operations are as 
follows:

NOTE D  ASSET DISPOSITIONS

     Sarnia, formerly Versar Virginia, Inc., a former wholly-owned real estate
subsidiary of Versar, was spun-off to Versar stockholders on June 30, 1994.
Sarnia was established in 1982 to own and operate Versar Center, the
headquarters buildings of Versar in Springfield, Virginia. On June 30, 1994,
Versar distributed to the holders of its common stock substantially all of the
common stock of Sarnia (the Distribution). The Distribution provided Versar
stockholders one share of Sarnia common stock for every outstanding share of
Versar common stock. The spin-off, although a divestiture for legal and tax
purposes, was not accounted for as a divestiture for accounting purposes until
January 1996, because the spin-off did not relieve Versar of the risks of
ownership due to Versar's guarantee of Sarnia's $12,400,000 debt at June 30,
1994.

     On January 25, 1996, Sarnia obtained new financing which reduced Versar's
guarantee of Sarnia's indebtedness from $12,400,000 to $1,500,000. Sarnia has
paid down the debt that Versar has guaranteed to $1,200,000 at June 30, 1998,
and accordingly Versar's current reserve is $1,200,000 against the guarantee.
Therefore, after the second quarter of fiscal year 1996, Versar no longer
includes the results of operations and financial position of Sarnia in the
consolidated financial statements. Sarnia's results of operations through
January 1, 1996 are presented as single line items in the Consolidated
Statements of Operations.

         In April 1997, Versar changed its line of credit facility from the
Riggs National Bank to NationsBank, N.A. The new line of credit provides for
advances up to $5,000,000 based on qualifying receivables less the $1,200,000
guarantee of Sarnia's term loan by Versar and the outstanding acquisition loan
balance. Interest on the borrowings is based on the lower of the 30 day London
Interbank Offered Rate (LIBOR) plus two hundred and fifty basis points (8.16% at
June 30, 1998). A commitment fee of 1/4% on the unused portion of the line of
credit is also charged. The line is guaranteed by the Company and each
subsidiary individually and is collectively secured by accounts receivable,
equipment and intangibles, plus all insurance policies on property constituting
collateral. Unused borrowing availability at June 30, 1998 was approximately
$1,336,000. Advances under the line are due upon demand or on November 30, 1998.
The loan has certain covenants related to maintenance of financial ratios. The
Company's covenants were modified at June 30, 1998 due to the SMC goodwill write
off discontinuance of SMC segments. Management believes that cash generated by
operations and borrowings available from the bank line of credit and the
extension of the line will be adequate to meet the working capital needs for
fiscal year 1999.

         Versar obtained a $2,000,000 promissory note from NationsBank on April
30, 1997 for the acquisition of SMC (See Note B). The interest on the note is
based on prime rate plus one half of one percent (.50%) per annum (9% at June
30, 1998). Principal payment commenced on May 31, 1997 and is scheduled to be
paid in full on April 30, 2000. At June 30, 1998, approximately $1,438,000 was
remaining on this loan.

         Versar has guaranteed certain debt of Sarnia Corporation (formerly
Versar Virginia, Inc., which was spun-off to Versar shareholders on June 30,
1994). On January 25, 1996, Sarnia refinanced its outstanding debt. As a result
of the refinancing, Versar's guarantee of Sarnia's debt has decreased from
approximately $12,400,000 to $1,500,000. The $1,500,000 note matures in five
years with $300,000 principal payment per year starting fiscal year 1997.
Sarnia's balance due on the term loan was $1,200,000 at June 30, 1998 and
accordingly, Versar reduced its reserve to $1,200,000 as of June 30, 1998. As
the term loan is repaid, the reserve will be reduced and added to Versar's
equity.

         The revolving bank line of credit amount outstanding based on average
daily balances for the years ended June 30, 1998, 1997, and 1996, approximated
$2,126,000, $306,000, and $673,000, respectively, and the weighted average
interest rates for such periods were 8.19%, 8.78%, and 10.82%, respectively. The
maximum amount outstanding approximated $4,449,700, $1,146,000, and $1,500,000
during fiscal years 1998, 1997, and 1996, respectively. Weighted average
interest rates are computed by relating the interest expense to the average
month-end balance.

         Interest payments were $339,000, $62,000, and $89,000 for the fiscal
years ended June 30, 1998, 1997, and 1996, respectively.

NOTE H  STOCK OPTIONS

         In November 1996, the stockholders approved the Versar 1996 Stock
Option Plan to provide employees and directors of the Company and certain other
persons an incentive to remain as employees of the Company and to encourage
superior performance. At June 30, 1997, 91,750 shares were granted under the
1996 Plan to SMC employees in connection with the acquisition. The Company also
maintains the Versar 1992 Stock Option Plan, the 1982 Incentive Stock Option
Plan, and a Non-Qualified Option Plan adopted in 1987. Options have been granted
from these plans to purchase the Company's common stock.

         At June 30, 1998, options to purchase an aggregate of 1,170,240 shares
of common stock were outstanding under the 1996, 1992 and 1982 Incentive Stock
Option Plans at per share exercise prices ranging from $2.375 to $5.375 and
options to purchase an aggregate of 343,835 shares were outstanding under the
Non-Qualified Stock Option Plan at per share exercise prices ranging from $2.375
to $3.563.

         Under the 1992 Plan, options have been granted and may be granted to
key employees at the fair market value on the date of grant and become
exercisable during the four-year period from the date of the grant at 20% per
year. Unexercised options are cancelled on the fifth anniversary of certain
grants under the 1982 Plan and on the tenth anniversary of the grant under the
remainder of the 1982 and 1992 Plans. Under the 1996 Stock Option Plan, options
may be granted at the fair market value on the date of grant. The vesting of
each option will be determined by the Administrator of the Plan. Each option
expires on the earlier of the last day of the tenth year after the date of grant
or the date the optionee ceases to be affiliated with the Company or its
subsidiaries.

         Options under the Incentive Stock Option 1982, 1992, and 1996 Plans are
as follows:

         In accordance with SFAS No. 123, the fair value approach to valuing 
stock options used for pro forma presentation has not been applied to stock
options granted prior to July 1, 1995. The compensation cost calculated under
the fair value approach is recognized over the vesting period of the stock
options.

         The weighted average fair value of options granted was $2.05 and $1.56
during 1998 and 1997, respectively. The fair value is estimated on the date of
grant using the Black-Scholes option pricing model with the following weighted
average assumptions used for grants in 1998 and 1997: expected volatility of
47.5% for both years; risk-free interest rate of 5%; and expected lives of five
years after the grant date.

      Realization of deferred tax assets is dependent upon generation of
sufficient income by Versar and in some cases sufficient income in specific
jurisdictions and by specific office locations. At June 30, 1997, the Company
had $132,000 of alternative minimum tax credit carryforwards which can be
carried forward indefinitely. The alternative minimum tax credit carryforward
may be used to offset regular tax liability in future years to the extent it
exceeds the alternative minimum tax liability. These carryforwards are reflected
as deferred tax assets. The Company has established a valuation allowance until
the probability of realization of these amounts becomes more certain.

         SMC has net operating loss carryforwards of approximately $9,500,000
for federal income tax purposes, which will expire in the years 1997 through
2011. Due to the substantial changes in SMC's ownership, there are annual
limitations on the amount of the carryforwards that can be utilized. The
utilization of the net operating losses is limited to approximately $300,000 per
year for the 13 remaining years. If the net operating losses are utilized, they
will favorably impact the results of operations as the related deferred tax
asset is fully reserved. SMC also has net operating loss carryforwards available
for use in the United Kingdom of approximately $1,000,000 which are available
indefinitely, as well as minor amounts available for use in other jurisdictions.

NOTE J   EMPLOYEE SAVINGS AND STOCK OWNERSHIP PLAN

         The Company has established an Employee Savings and Stock Ownership
Plan (ESSOP) for the benefit of its employees and those of its subsidiaries. To
be eligible to participate in the plan, an employee must have been

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

employed for one year with at least 1,000 hours of service. The plan includes an
Employee Stock Ownership Plan (ESOP) and an Employee Savings Plan (401(k)).

         Contributions to the ESOP are made at the discretion of the Company in
the form of the Company's stock or cash, which is invested by the plan's
trustees in the Company's stock. No contributions were made in fiscal years
1998, 1997, and 1996, respectively.

         The Employee Savings Plan was adopted in accordance with Section 401(k)
of the Internal Revenue Code. Under the plan, participants may elect to defer up
to 15% of salary through contributions to the plan, which are invested in
selected mutual funds or used to buy insurance. The Company will match qualified
contributions with a contribution of 100% of each employee's contribution up to
4% of the employee's salary. This contribution may be in the Company's stock or
cash, which will be invested by the plan's trustees in the Company's stock.
Company matching contributions approximated $514,000, $492,000, and $473,000,
for fiscal years 1998, 1997, and 1996, respectively.

         All contributions to the 401(k) Plan vest immediately. Contributions to
the ESOP vest ratably with years of service such that full vesting occurs after
five years of credited service.

         Geomet Technologies, Inc. ("Geomet"), a wholly-owned subsidiary, has a
profit-sharing retirement plan for the benefit of its employees. Contributions
are made at the discretion of Geomet's Board of Directors. In fiscal year 1998
contributions approximated $25,000, but there were no contributions in fiscal
years 1997 and 1996. Vesting occurs over time, such that an employee is 100%
vested after seven years of participation.

NOTE K  COMMITMENTS AND CONTINGENCIES

         Versar has a substantial number of U.S. Government contracts, the costs
of which are subject to audit by the Defense Contract Audit Agency. All fiscal
years through 1993 have been audited and closed. Management believes that the
effect of disallowed costs, if any, for the periods not yet audited will not
have a material adverse effect on the consolidated financial position and
results of operations.

         The Company leases approximately 210,000 square feet of office space,
including space leased from Sarnia, as well as data processing and other
equipment under agreements expiring through 2009. Minimum future obligations
under operating leases are as follows:

         Certain of the lease payments are subject to adjustment for increases
in utility costs and real estate taxes. Total rental expense approximated
$2,898,000, $2,658,000 and $2,467,000, for 1998, 1997 and 1996, respectively.

         Versar is a defendant in lawsuits that have arisen in the ordinary
course of its business. Management does not believe that the outcome of these
lawsuits will have a material adverse effect on the Company's consolidated
financial position and results of operations.

making such investigation as Purchaser may desire, and Seller shall furnish
Purchaser such information concerning Seller's Business or the Purchased Assets
as Purchaser may request. Seller shall assist Purchaser in making such
investigation and shall cause its counsel, accountants, engineers, consultants
and other non-employee representatives to be reasonably available to Purchaser

shall limit or affect the representations, warranties, covenants and indemnities
of Seller and the Shareholders hereunder, each of which shall survive any such

disclosure thereof by Seller to Purchaser;

               (c) any information which comes into the public domain through no

non-employee representatives of Seller) having the legal right to make such
disclosure; or

               (e) any information which is required to be disclosed by order of
any court or other tribunal of competent jurisdiction.

           2.3 COOPERATION. The parties shall cooperate fully with each other

required to be taken as part of their respective obligations under this

<PAGE>   12
the prior written consent of the other parties, no party hereto may take any
intentional action that would cause the conditions precedent to the obligations
of the parties hereto to effect the transactions contemplated hereby not to be
fulfilled, including, without limitation, taking or causing to be taken any
action which would cause the representations and warranties made by such party
herein not to be true, correct and complete as of the Closing.

           2.4 EXPENSES. All expenses incurred by Purchaser in connection with
the authorization, preparation, execution and performance of this Agreement,

claiming to have been employed by or on behalf of Seller.

           2.6 EMPLOYMENT AGREEMENTS. If the transactions contemplated by this
Agreement are consummated at the Closing, then Purchaser and Shareholders agree
to execute employment agreements in the form attached hereto as Exhibit B.

           2.7 COVENANT AGAINST COMPETITION.

               (a) In order to induce Purchaser to enter into this Agreement and
purchase the Purchased Assets as provided herein, and for the consideration
specified in Paragraph 2.7(e) below, Seller and each Shareholder agrees that,
during Shareholders' employment by Purchaser, and for six months thereafter,
they shall not compete with the business of Purchaser, its subsidiaries or
affiliates within the geographic area of the states of Virginia, North Carolina,
West Virginia, Maryland and the District of Columbia. For the purpose of this
Agreement, activities among others which shall be deemed competitive include:
(i) owning any portion of or consulting for or employment by any entity
competitive with the services performed by Purchaser; (ii) encouraging and
soliciting or attempting to solicit any customers of Purchaser, its subsidiaries
or affiliates (including those who are or have been customers of Purchaser or
its subsidiaries or affiliates during the previous 24 months) to become a
customer of Shareholder or any other person except through normal competitive
bidding; and (iii) encouraging





                                      -8-
<PAGE>   13
any employee of Purchaser, its subsidiaries or affiliates to become an employee
of Shareholder or of any other person.

               (b) Shareholders acknowledge that the damage to Purchaser, its
subsidiaries and affiliates resulting from a breach of this Paragraph 2.7 may
cause irreparable injury. Therefore, in the event of any such breach, Purchaser,
its subsidiaries and affiliates shall be entitled to seek such remedies as are
available at law or equity to restrain and enjoin Shareholders from continuing
to violate the provisions of this paragraph.


               (c) Seller and each Shareholder agrees that each of them will
not, without the prior written consent of Purchaser, for their own account or
jointly with another, directly or indirectly, for or on behalf of any
individual, partnership, corporation or other legal entity, as principal, agent
or otherwise, use or authorize any other person to use the name "The Greenwood
Partnership" or any name similar thereto, in connection with the sale or
performance of any professional engineering or architectural services. On the
Closing Date, Seller shall, and the Shareholders shall cause Seller to change
its name, and the names of any of Seller's subsidiaries, so as not to
incorporate the name "The Greenwood Partnership" or any other confusingly
similar name.

               (d) Notwithstanding anything herein to the contrary (i) it shall
not be a breach of the covenants contained in Paragraph 2.7(a) above for Seller
or any Shareholder to own not more than two percent (2.0%) of the capital stock
of any corporation whose shares are publicly traded, and (ii) the covenants
described in this Paragraph 2.7 shall apply only if the transactions
contemplated by this Agreement are consummated at the Closing.

               (e) In consideration of the agreements of Seller and the
Shareholders not to compete as provided in this Paragraph 2.7, Purchaser shall
pay to Shareholders $18,000 allocated pursuant to the Exhibit E attached hereto.


               (f) In the event that any part of this Paragraph 2.7 shall be
deemed a court of competent jurisdiction to be in violation of applicable law
for any reason whatsoever, than such part shall not be deemed to be void, but
shall be deemed to be modified so as to be valid and enforceable, and the
remaining provisions of this Paragraph 2.7 or of this Agreement shall not be
affected. The provisions of Paragraph 2.7 shall survive the termination of
Shareholders employment for any reason.

           2.8 PUBLICITY. All press releases and other public announcements
respecting the subject matter hereof shall be made only with the mutual
agreement of the parties hereto; provided,





                                      -9-
<PAGE>   14
however, that the parties understand that Purchaser is a publicly held company
with its shares traded on the American Stock Exchange and may make such
announcements as may be necessary or convenient to comply with the rules and
regulations of the American Stock Exchange and any and all applicable federal
and state securities laws.

           2.9 WAIVER OF BULK SALES LAW COMPLIANCE. Compliance with the bulk
sales laws of the State of Virginia and in any other jurisdiction where Seller
conducts its business is hereby waived by Purchaser, and Seller and the
Shareholders hereby jointly and severally agree to defend, indemnify and hold
harmless Purchaser and its affiliates from and against any claims by any person
arising out of or due to the failure to comply with such bulk sales laws,
including, without limitation, any claims by any Person against all or any part

further, the liability of Shareholders Charles R. Bourn, Jr., Randy G. Parish
and Randal S. Vanghan to reimburse the Indemnities shall be limited to $50,000
each.


           8.3 DEFENSE OF CLAIMS.

               (a) If any claim or action by a third party arises after the
Closing Date for which Seller and the Shareholders may be liable under the terms
of this Agreement, then Indemnities shall notify Seller (who shall also act as
agent for the Shareholders for purposes of such claim or action) within a
reasonable time after such claim or action arises and is known to Indemnities,
and shall give Seller a reasonable opportunity:

                          (i) to conduct any proceedings or negotiations in
           connection therewith and necessary or appropriate to defend
           Indemnities;

                          (ii) to take all other required steps or
           proceedings to settle or defend any such claim or action; and

                          (iii) to employ counsel to contest any such claim
           or action in the name of Indemnities or otherwise.

The expenses of all proceedings, contests or lawsuits with respect to such
claims or actions shall be borne by Seller and the Shareholders.  If Seller and
the Shareholders wish to assume the defense of such claim or action, then
Seller shall give written notice to Indemnities within 30 days after notice
from Indemnities of such claim or action (unless the claim or action reasonably
requires a response in less than 30 days after the notice is given to Seller,
in which event they shall notify Indemnities at least 10 days prior to such
reasonably required response date), and Seller and the Shareholders shall
thereafter assume the defense of any such claim or liability, through counsel
reasonably satisfactory to Indemnities; provided that Indemnities may
participate in such





                                      -32-
<PAGE>   37
defense at their own expense and shall, in any event, have the right to control
the defense of the claim or action.

               (b) If Seller and the Shareholders do not assume the defense of,
or if after so assuming Seller and the Shareholders fail to defend, any such
claim or action, then Indemnities may defend against such claim or action in
such manner as they may deem appropriate (provided that Seller and the
Shareholders may participate in such defense at their own expense) and
Indemnities may settle such claim or litigation on such terms as they may deem
appropriate, and Seller and the Shareholders jointly and severally shall
promptly reimburse Indemnities for the amount of all expenses, legal and
otherwise, reasonably and necessarily incurred by Indemnities in connection with
the defense against and settlement of such claim or action. If no settlement of
such claim or litigation is made, Seller and the Shareholders jointly and
severally shall satisfy any judgment rendered with respect to such claim or in
such action, before Indemnities are required to do so, and pay all expenses,
legal or otherwise, reasonably and necessarily incurred by Indemnities in the
defense of such claim or litigation.

               (c) If a judgment is rendered against any of the Indemnities in
any action covered by the indemnification hereunder, or any lien in respect of
such judgment attaches to any of the assets of any of the Indemnities, Seller
and the Shareholders shall immediately upon such entry or attachment pay such
judgment in full or discharge such lien unless, at the expense and direction of
Seller and the Shareholders, an appeal is taken under which the execution of the
judgment or satisfaction of the lien is stayed. If and when a final judgment is
rendered in any such action, Seller and the Shareholders shall forthwith pay
such judgment or discharge such lien before any of Indemnities is compelled to
do so.


9.   SURVIVAL OF REPRESENTATIONS AND OTHER PROVISIONS.

           9.1 SURVIVAL. The representations, warranties, covenants, agreements
and indemnifications of the parties contained in this Agreement or in any
writing delivered pursuant to the provisions of this Agreement shall survive any
investigation heretofore or hereafter made by Purchaser and the consummation of
the transactions contemplated herein and shall continue in full force and effect
for the period (the "Survival Period") beginning on the Closing Date and
continuing until February 1, 2001. Provided, however, that the Survival Period
shall be extended automatically to include any time period necessary to resolve
a specific claim for indemnification which was made before expiration of the
Survival Period but not resolved prior to its expiration;





                                      -33-
<PAGE>   38
and provided, further, that any such extension shall apply only as to claims
asserted and not so resolved within the Survival Period.

           9.2 LIABILITIES NOT ASSUMED. Notwithstanding the provisions of
Paragraph 9.1 above, Seller shall remain liable, during the Survival Period and
thereafter, for all liabilities and obligations of Seller not assumed pursuant
to Paragraph 1.5 above, including, without limitation, the liabilities and
obligations specified in Paragraph 1.6 above.

10.        TERMINATION.

           10.1 TERMINATION FOR CERTAIN CAUSES. This Agreement may be terminated
at any time prior to or on the Closing Date by Seller or Purchaser upon written
notice to the other party as follows, and, upon such termination of this
Agreement, no party hereto shall have any liability to the other:

               (a) By Purchaser, if a material adverse change in the financial
condition or business of Seller shall have occurred, or any substantial part of
the Purchased Assets of Seller are destroyed due to fire or other casualty.

               (b) By Purchaser if the terms, covenants or conditions of this
Agreement to be complied with or performed by the Shareholders and Seller at or
before the Closing Date shall not have been complied with or performed and such
noncompliance or nonperformance shall not have been waived by Purchaser.

               (c) By Purchaser, if there is any fact or condition with respect
to Seller's Business, the Purchased Assets, or any obligation of Seller, which
materially and adversely affects such business, assets, or the Assumed
Liabilities, or the value or continuance of the Seller's Business.

               (d) By Seller and the Shareholders, if the terms, covenants or
conditions of this Agreement to be complied with or performed by Purchaser at or
before the Closing Date shall not have been complied with or performed and such
noncompliance or nonperformance shall not have been waived by Seller and the
Shareholders.

               (e) By any party, if any action, suit or proceeding shall have
been instituted or threatened against any party to this Agreement to restrain or
prohibit, or to obtain substantial damages in respect of, this Agreement or the
consummation of the transactions contemplated herein, which, in the good faith
opinion of any party, makes consummation of the transactions herein contemplated
inadvisable.

11.  POWER-OF-ATTORNEY.

           11.1 APPOINTMENT OF AGENT. The Shareholders and each of them, hereby
irrevocably constitute and appoint Seller (the "Agent") as their agent and
attorney-in-fact to modify, amend or otherwise change this Agreement, or any of
its terms or provisions (including modifications, amendments or changes
subsequent to Closing), to take all actions and to execute all documents
(including all actions and documents required under Section 6 hereof) necessary

to take all actions and to execute all documents which may be necessary or
desirable in connection therewith, to give and receive consents and all notices
hereunder, to negotiate and settle claims for indemnification under Section 8
hereof, and to perform any other act arising under or pertaining to this
Agreement and the transactions contemplated hereby. The Shareholders, and each
of them, agree that service of process upon the Agent in any action or
proceeding arising under or pertaining to this Agreement shall be deemed to be
valid service of process upon the Shareholders, and any claim by Purchaser
against the Shareholders, or any of them, in respect to this Agreement may be
asserted against, and settled with, the Agent. The Agent shall be deemed to have
accepted the appointment herein upon his execution of this Agreement.

           11.2 LIABILITY OF AGENT. Nothing contained herein shall be deemed to
make the Agent personally liable to the Shareholders because of service in his
capacity as agent and attorney-in-fact. In performing any of his duties
hereunder, the Agent shall not incur any liability to the Shareholders for
losses, damages, liabilities or expenses, except for his own wilful default.

           11.3 IRREVOCABLE; BINDING ON SUCCESSORS, ETC. It is expressly
understood and agreed that this power of attorney and the agency created hereby
is coupled with an interest of the respective parties hereto and shall be
binding and enforceable on and against the respective heirs, personal
representatives, successors and assigns of the Shareholders, and each of them,
and this power of attorney shall not be revoked or terminated by the death,
disability, bankruptcy or incompetency of the Shareholders, or any of them, but
shall continue to be binding and enforceable by the Agent, Purchaser and their
respective successors and on and against the heirs, personal representatives,
successors and assigns of the Shareholders in the manner provided herein.

contained herein may be exercised and shall be applicable and binding only to
the extent that they do not violate any applicable laws and are intended to be

unenforceable by a court of competent jurisdiction, it is the intention of the

agreement with respect to the subject matter hereof and all such remaining

waiver is evidenced by a writing signed by such party. No failure on the part of
any party hereto to exercise, and no delay in exercising any right, power or
remedy created hereunder, shall operate as a waiver thereof, nor shall any
single or partial exercise of any right, power or remedy by any such party
preclude any other or further exercise thereof or the exercise of any other
right, power or remedy. No waiver by any party hereto to any breach of or
default in any term or condition of this Agreement shall constitute a waiver of
or assent to any succeeding breach of or default in the same or any other term
or condition hereof.

the daily London Interbank Offered Rate for thirty (30) days U.S. Dollar
deposits as quoted by the Lender as of 11:00 A.M. (Washington, D.C., time) (the
"LIBOR Rate"). The interest rate on all sums accruing interest at the LIBOR
Rate under this Note shall change immediately and contemporaneously with any
change in the LIBOR Rate.

                 (b)    In addition, so long as no event of default or any act,
event or condition which, with notice or the passage of time or both, would
constitute an event of default under any Financing Document has occurred and is
continuing, the Borrowers shall have the right to elect that specified amounts
advanced under this Note in a minimum amount of $100,000 and increments of
$50,000, bear interest at the Prime Rate per annum. For purposes hereof, the
"Prime Rate" means the fluctuating prime rate of interest established and
declared by the Lender from time to time. The Prime Rate does not necessarily
represent the lowest rate of interest charged by the Lender to its borrowers.

                 (c)    All interest payable under the terms of this Note shall
be calculated on the basis of a 360-day year and the actual number of days
elapsed.

                 (d)    In respect to any interest rate election hereunder and
any transactions contemplated hereby, the Borrowers authorize the Lender to
accept, rely upon, act upon and comply with, any verbal or written
instructions, requests, confirmations and orders of the



<PAGE>   3
President and Chief Executive Officer, the Vice President, Treasurer & Chief
Financial Officer and Vice President, Secretary & General Counsel on behalf of
the Borrowers. The Borrowers acknowledge that the transmission between the
Borrowers and the Lender of any such instructions, requests, confirmations and
orders involves the possibility of errors, omissions, mistakes and
discrepancies and agrees to adopt such internal measures and operational
procedures to protect its interests. By reason thereof, the Borrowers hereby
assume all risk of loss and responsibility for, release and discharge the
Lender from any and all responsibility or liability for, and agree to
indemnify, reimburse on demand and hold the Lender harmless from, any and all
claims, actions, damages, losses, liability and expenses by reason of, arising
out of or in any way connected with or related to, (i) the Lender's acceptance,
reliance and actions upon, compliance with or observation of any such
instructions, requests, confirmations or orders, and (ii) any such errors,
omissions, mistakes and discrepancies, except those caused by the Lender's
gross negligence or willful misconduct.

          2.     Payments and Maturity.  The unpaid Principal Sum, together with
interest thereon at the rate or rates provided above, shall be payable as
follows:

                 (a)    Interest only on the unpaid Principal Sum shall be due
and payable monthly, commencing February 1, 1998, and on the same day of each
month thereafter to maturity; and

                 (b)    Unless sooner paid, the unpaid Principal Sum, together
with interest accrued and unpaid thereon, shall be due and payable in full on
November 30, 1998. 

          The fact that the balance hereunder may be reduced to zero from time 
to time pursuant to the Financing Agreement will not affect the continuing 
validity of this Note or the Financing





                                       3
<PAGE>   4
Agreement, and the balance may be increased to the Principal Sum after any such
reduction to zero.

          3.     DEFAULT INTEREST.  Upon the occurrence of an Event of Default 
(as hereinafter defined), the unpaid Principal Sum shall bear interest 
thereafter at a rate (the "Default Rate") two percent (2%) per annum in excess 
of the then current rate or rates of interest hereunder until such Event of 
Default is cured.

          4.     LATE CHARGES.  If the Borrowers shall fail to make any payment 
under the terms of this Note within ten (10) days after the date such payment is
due, the Borrowers shall pay to the Lender on demand a late charge equal to five
percent (5%) of such payment.

          5.     APPLICATION AND PLACE OF PAYMENTS.  All payments, made on
account of this Note shall be applied first to the payment of any late charge
then due hereunder, second to the payment of accrued and unpaid interest then
due hereunder, and the remainder, if any, shall be applied to the unpaid
Principal Sum. All payments on account of this Note shall be paid in lawful
money of the United States of America in immediately available funds during
regular business hours of the Lender at its principal office in McLean,
Virginia or at such other times and places as the Lender may at any time and
from time to time designate in writing to the Borrowers. The Lender is
authorized to deduct any payment (including payments of principal and/or
interest as above provided) from the Borrowers' Account Number 4113103748 on or
after the date the payment is due; provided, however, that such authorization
shall not be deemed to relieve the Borrowers from their obligation to make
such payment when it is due.

          6.     PREPAYMENT.  The Borrowers may prepay the Principal Sum in
whole or in part without premium or penalty.

          7.     FINANCING AGREEMENT AND OTHER FINANCING DOCUMENTS.  This Note
is the "Second Restated Note" described in that certain Third Amendment to
Financing and Security Agreement of even date herewith by and among the
Borrowers and the Lender, which Third Amendment to Financing and Security
Agreement, further amends that certain Financing and Security Agreement dated
March 31, 1997 (the "Original Financing Agreement") by and among Versar and
Geomet (the "Original Borrowers"). The Original Financing Agreement has been
amended by that certain First Amendment to Financing and Security Agreement
dated April 30, 1997, by and among the Original Borrowers and the Lender and
which Original Financing Agreement was further amended by that certain Second
Amendment to Financing and Security Agreement dated November 30, 1997 by and
among the Original Borrowers, SMC, SMC Environmental, SMC McEver and SMC
Business and the Lender (the Original Financing Agreement, as amended,
modified, restated, substituted, extended and renewed at any time and from time
to time, is called the "Financing Agreement"). The indebtedness evidenced by
this Note is included within the meaning of the term "Obligations" as defined
in the Financing Agreement. This Note increases, amends and restates in its
entirety that certain Amended and Restated Revolving Promissory Note in the
maximum principal amount of Three Million Dollars ($3,000,000) dated November
30, 1997 (the "First Restated Note") from the Original Borrowers, SMC, SMC
Environmental, SMC McEver and SMC Business in favor of the Lender.  The term
"Financing Documents" as used in this Note, shall mean collectively this Note,
each Acquisition Note, the Financing Agreement and any other instrument,
agreement, or document previously, simultaneously, or hereafter executed and
delivered by any of the Borrowers and/or any other person, singularly or
jointly with any other person, evidencing, securing, guaranteeing, or in





                                       5
<PAGE>   6
connection with the Principal Sum, this Note and/or the Financing Agreement.
It is expressly understood and agreed that the indebtedness evidenced by the
First Restated Note has not been extinguished or discharged hereby. The
Borrowers and the Lender agree that the execution of this Note is not intended
and shall not cause or result in a novation with regard to the First Restated
Note.

          8.     SECURITY.  This Note is secured as provided in the Financing
Agreement.

          9.     EVENTS OF DEFAULT.  The occurrence of any one or more of the
following events shall constitute an event of default (individually, an "Event
of Default" and collectively, the "Events of Default") under the terms of this
Note:

                 (a)    The failure of the Borrowers to pay to the Lender
within five (5) days of when due any and all amounts payable by the Borrowers
to the Lender under the terms of this Note; or

                 (b)    The occurrence of an event of default (as defined
therein) under the terms and conditions of any of the other Financing
Documents.

          10.    REMEDIES.  Upon the occurrence of an Event of Default, at the
option of the Lender, all amounts payable by the Borrowers to the Lender under
the terms of this Note shall immediately become due and payable by the
Borrowers to the Lender without notice to the Borrowers or any other person,
and the Lender shall have all of the rights, powers, and remedies available
under the terms of this Note, any of the other Financing Documents and all
applicable laws. The Borrowers and all endorsers, guarantors, and other
parties who may now or in the future be primarily or secondarily liable for the
payment of the indebtedness evidenced by this Note hereby severally waive
presentment, protest and demand, notice of protest, notice of





                                       6
<PAGE>   7
demand and of dishonor and non-payment of this Note and expressly agree that
this Note or any payment hereunder may be extended from time to time without in
any way affecting the joint and several liability of the Borrowers, guarantors
and endorsers.

          Until such time as the Lender is not committed to extend further
credit to the Borrowers and all Obligations of the Borrowers to the Lender have
been indefeasibly paid in full in cash, and subject to and not in limitation of
the provisions set forth in the next following paragraph below, no Borrower
shall have any right of subrogation (whether contractual, arising under the
Bankruptcy Code or otherwise), reimbursement or contribution from any Borrower,
or any guarantor nor any right of recourse to its security for any of the debts
and obligations of any Borrower which are the subject of this Note. Except as
otherwise expressly permitted by the Financing Agreement, any and all present
and future debts and obligations of any other to any Borrower are hereby
subordinated to the full payment and performance of all present and future
debts and obligations to the Lender under this Note and the Financing Agreement
and the Financing Documents, provided, however, notwithstanding anything set
forth in this Note to the contrary, prior to the occurrence of a payment
Default, the Borrowers shall be permitted to make payments on account of any of
such present and future debts and obligations from time to time in accordance
with the terms thereof.

          The Borrowers further agree that, if any payment made by the
Borrowers, or any other person is applied to this Note and is at any time
annulled, set aside, rescinded, invalidated, declared to be fraudulent or
preferential or otherwise required to be refunded or repaid, or the proceeds of
any property hereafter securing this Note is required to be returned by the
Lender to any Borrower, their estate, trustee, receiver or any other party,
including, without limitation, such





                                       7
<PAGE>   8
Borrower, under any bankruptcy law, state or federal law, common law or
equitable cause, then, to the extent of such payment or repayment, such
Borrower's liability hereunder (and any lien, security interest or other
collateral securing such liability) shall be and remain in full force and
effect, as fully as if such payment had never been made, or, if prior thereto
any such lien, security interest or other collateral hereafter securing such
the Borrower's liability hereunder shall have been released or terminated by
virtue of such cancellation or surrender, this Note (and such lien, security
interest or other collateral) shall be reinstated in full force and effect, and
such prior cancellation or surrender shall not diminish, release, discharge,
impair or otherwise affect the obligations of such Borrower of the amount of
such payment (or any lien, security interest or other collateral securing such
obligation).

          The JOINT AND SEVERAL obligations of each Borrower under this Note
shall be absolute, irrevocable and unconditional and shall remain in full force
and effect until the outstanding principal of and interest on this Note and all
other Obligations or amounts due hereunder and under the Financing Agreement
and the Financing Documents shall have been indefeasibly paid in full in cash
in accordance with the terms thereof and this Note shall have been canceled.

          11.    EXPENSES.  The Borrowers jointly and severally promise to pay
to the Lender on demand by the Lender all costs and expenses incurred by the
Lender in connection with the collection and enforcement of this Note,
including, without limitation, reasonable attorneys' fees and expenses and all
court costs.

          12.    NOTICES.  Any notice, request, or demand to or upon the
Borrowers or the Lender shall be deemed to have been properly given or made
when delivered in accordance with Section 11.01 of the Financing Agreement.

          13.    MISCELLANEOUS.  Each right, power, and remedy of the Lender as
provided for in this Note or any of the other Financing Documents, or now or
hereafter existing under any applicable law or otherwise shall be cumulative
and concurrent and shall be in addition to every other right, power, or remedy
provided for in this Note or any of the other Financing Documents or now or
hereafter existing under any applicable law, and the exercise or beginning of
the exercise by the Lender of any one or more of such rights, powers, or
remedies shall not preclude the simultaneous or later exercise by the Lender of
any or all such other rights, powers, or remedies. No failure or delay by the
Lender to insist upon the strict performance of any term, condition, covenant,
or agreement of this Note or any of the other Financing Documents, or to
exercise any right, power, or remedy consequent upon a breach thereof, shall
constitute a waiver of any such term, condition, covenant, or agreement or of
any such breach, or preclude the Lender from exercising any such right, power,
or remedy at a later time or times. By accepting payment after the due date of
any amount payable under the terms of this Note, the Lender shall not be deemed
to waive the right either to require prompt payment when due of all other
amounts payable under the terms of this Note or to declare an Event of Default
for the failure to effect such prompt payment of any such other amount. No
course of dealing or conduct shall be effective to amend, modify, waive,
release, or change any provisions of this Note.

          14.    PARTIAL INVALIDITY.  In the event any provision of this Note
(or any part of any provision) is held by a court of competent jurisdiction to
be invalid, illegal, or unenforceable in





                                       9
<PAGE>   10
any respect, such invalidity, illegality, or unenforceability shall not affect
any other provision (or remaining part of the affected provision) of this Note;
but this Note shall be construed as if such invalid, illegal, or unenforceable
provision (or part thereof) had not been contained in this Note, but only to
the extent it is invalid, illegal, or unenforceable.

          15.    CAPTIONS.  The captions herein set forth are for convenience
only and shall not be deemed to define, limit, or describe the scope or intent
of this Note.

          16.    APPLICABLE LAW.    Each Borrower acknowledges and agrees that
this Note shall be governed by the laws of the Commonwealth of Virginia, even
though for the convenience and at the request of the Borrowers, this Note may
be executed elsewhere.

          17.    WAIVER OF TRIAL BY JURY.  EACH BORROWER HEREBY WAIVES TRIAL
BY JURY IN ANY ACTION OR PROCEEDING TO WHICH EITHER BORROWER AND THE LENDER MAY

THIS WAIVER BY INDEPENDENT LEGAL COUNSEL, SELECTED OF ITS OWN FREE WILL, AND
THAT IT HAS HAD THE OPPORTUNITY TO DISCUSS THIS WAIVER WITH COUNSEL.

          18.    ARBITRATION.   ANY CONTROVERSY OR CLAIM BETWEEN OR AMONG THE
PARTIES HERETO INCLUDING BUT NOT LIMITED TO THOSE ARISING OUT OF THIS NOTE OR
ANY RELATED INSTRUMENTS, AGREEMENTS OR DOCUMENTS, INCLUDING ANY CLAIM BASED ON
OR ARISING FROM AN ALLEGED TORT, SHALL BE DETERMINED BY BINDING ARBITRATION IN
ACCORDANCE WITH THE FEDERAL ARBITRATION ACT (OR IF NOT APPLICABLE, THE

COMMERCIAL DISPUTES OF ENDISPUTE, INC., D/B/A J.A.M.S./ENDISPUTE ("J.A.M.S.")

AGREEMENT OR DOCUMENT MAY BRING ANY ACTION, INCLUDING A SUMMARY OR EXPEDITED
PROCEEDING, TO COMPEL ARBITRATION OF ANY CONTROVERSY OR CLAIM TO WHICH THIS

THE RIGHT OF THE LENDER: (A) TO EXERCISE SELF HELP REMEDIES SUCH AS (BUT NOT

COLLATERAL, OR (C) TO OBTAIN FROM A COURT PROVISIONAL OR ANCILLARY REMEDIES
SUCH AS (BUT NOT LIMITED TO) INJUNCTIVE RELIEF, WRIT OF POSSESSION OR THE
APPOINTMENT OF A RECEIVER. THE LENDER MAY EXERCISE SUCH SELF HELP RIGHTS,
FORECLOSE UPON SUCH PROPERTY, OR OBTAIN SUCH PROVISIONAL OR ANCILLARY REMEDIES
BEFORE, DURING OR AFTER THE PENDENCY OF ANY ARBITRATION PROCEEDING BROUGHT
PURSUANT TO THIS INSTRUMENT, AGREEMENT OR DOCUMENT. NEITHER THE EXERCISE OF

and C), upon receipt of a duly executed delivery order or Notice of Award (NOA)
signed by the Contracting Officer.  The Contractor may visit the site to
perform any necessary and required efforts prior to actual mobilization and
start-up at the site.  Pursuant to SCR H-011 and AFMC FAR Supplement
5352.228-9003, the contractor shall not commence actual remedial
action/construction work at the site until receipt of a written
Notice-To-Proceed (NTP) signed by the Contracting Officer.  Prior to issuance
of the NTP, the Government reserves the right to convene a post-award
pre-construction conference at the applicable site. The contractor shall attend
any such conference as directed by the Contracting Officer Representative.  The
contractor shall not deliver any materials or equipment to the site prior to
receipt of an NTP or a written authorization signed by the Contracting Officer
Representative.

H-014             TEAMING ARRANGEMENTS

                 (a) If this contract was awarded from an offer submitted on
 the basis of a major teaming arrangement, the government's consideration of
 the contractor for placement of

                                                                   Page 30 of 78


delivery orders will reflect the teaming arrangement.  In the event that the
teaming arrangement is dissolved or significantly changed, the government
reserves the right to reconsider the suitability of the changed arrangements
for purposes of issuing delivery orders.

                 (b) Your teaming approach and major team members provided in
your proposal are hereby incorporated as set forth in AFMC FAR clause
5352.215.9005(JUL 1997).  The major teaming partners are listed below:

Sverdrup Civil, Inc., Maryland Heights, MO
Granite Construction Company, 735 W. Beach St., Watsonville, CA
Ferguson-Harbour, Inc., 340 Rockland Road, Hendersonville, TN
ERM Program Management Company, 855 Springdale Dr. Exton PA

                 (c) Should it become advantageous to deviate from the initial
teaming arrangement, the contractor should request approval from the
Contracting Officer before making such arrangements.

                 (d) This does not authorize contractor team arrangements in
violation of antitrust statutes or limit the Government's rights to require
consent to subcontract.  The prime contractor is held fully responsible for
contract performance, regardless of any team arrangement between the prime
contractor and its subcontractors.

                 (e) Notwithstanding the above teaming arrangements and issues
relating to consent, all teaming arrangement (subcontract) pricing must be
supported in accordance with Far 15.806. Subcontract cost and pricing data, as
appropriate, should be presented in the delivery order proposal.

III.  FAR CLAUSES IN FULL TEXT

                 A.  THE FOLLOWING FULL TEXT CLAUSES SHALL BE APPLICABLE TO BOTH
COST-REIMBURSEMENT AND FIXED-PRICE DELIVERY ORDER EFFORTS.

52.223-3         HAZARDOUS MATERIAL IDENTIFICATION AND MATERIAL SAFETY DATA
(JAN 1997)

                 (a)  "Hazardous material," as used in this clause, includes
any material defined as hazardous under the latest version of Federal Standard
No. 313 (including revisions adopted during the term of the contract).

                 (b)  The offeror must list any hazardous material, as defined
in paragraph (a) of this clause, to be delivered under this contract.  The
hazardous material shall be properly identified and include any applicable
identification number, such as National Stock Number or Special Item Number.
This information shall also be included on the Material Safety Data Sheet
submitted under this contract.

                 Material (If none, insert "None")       Identification No.
                 [AS DETERMINED AT DELIVERY ORDER LEVEL]

                 (c) The apparently successful offeror, by acceptance of the
contract, certifies that the list in paragraph (b) of this clause is complete.
This list must be updated during

<PAGE>   40
                                                                   Page 40 of 78


performance of the contract whenever the Contractor determines that any other
material to be delivered under this contract is hazardous.

                 (d)  The apparently successful offeror agrees to submit, for
each item as required prior to award, a Material Safety Data Sheet, meeting the
requirements of 29 CFR 1910.1200(g) and the latest version of Federal Standard
No. 313, for all hazardous material identified in paragraph (b) of this clause.
Data shall be submitted in accordance with Federal Standard No. 313, whether or
not the apparently successful offeror is the actual manufacturer of these
items.  Failure to submit the Material Safety Data Sheet prior to award may
result in the apparently successful offeror being considered nonresponsible and
ineligible for award.

                 (e)  If, after award, there is a change in the composition of
the item(s) or a revision to Federal Standard No.  313, which renders
incomplete or inaccurate data submitted under paragraph (d) of this clause or
the certification submitted under paragraph (c) of this clause, the Contractor
shall promptly notify the Contracting Officer and resubmit the data.

                 (f)  Neither the requirements of this clause nor any act or
failure to act by the Government shall relieve the Contractor of any
responsibility or liability for the safety of  Government, Contractor, or
subcontractor personnel or property.

                 (g)  Nothing contained in this clause shall relieve the
Contractor from complying with applicable Federal, State, and local laws,
codes, ordinances, and regulations (including the obtaining of licenses and
permits) in connection with hazardous material.

                 (h) The Government's rights in data furnished under this
contract with respect to hazardous material are as follows:

                           (1) To use, duplicate and disclose any data to which
this clause is applicable.  The purposes of this right are to:
                                  (i) Apprise personnel of the hazards to which
they may be exposed in using handling, packaging, transporting, or disposing of
hazardous materials;

                                 (ii) Obtain medical treatment for those
affected by the material; and

                                (iii) Have others use, duplicate, and disclose
the data for the Government for these purposes.

                           (2) To use, duplicate, and disclose data furnished
under this clause, in accordance with subparagraph (h)(1) of this clause, in
precedence over any other clause of this contract providing for rights in data.

                             (3) The Government is not precluded from using
similar or identical data acquired from other sources.

                      (b) Wherever in the specifications or upon the drawings
the words "directed", "required", "ordered", "designated", "prescribed", or
words of like import are used, it shall be understood that the "direction",
"requirement", "order", "designation", or "prescription", of the Contracting
Officer is intended and similarly the words "approved", "acceptable",
"satisfactory", or words of like import shall mean "approved by", or
"acceptable to", or "satisfactory to" the Contracting Officer, unless otherwise
expressly stated.

                      (c) Where "as shown", "as indicated", "as detailed", or
words of similar import are used, it shall be understood that the reference is
made to the drawings accompanying this contract unless stated otherwise. The
word "provided" as used herein shall be understood to mean "provide complete in
place", that is "furnished and installed".

                      (d) Shop drawings means drawings, submitted to the
Government by the Contractor, subcontractor, or any lower tier subcontractor

Contractor shall coordinate all such drawings, and review them for accuracy,
completeness, and compliance with contract requirements and shall indicate its
approval thereon as evidence of such coordination and review.  Shop drawings
submitted to the Contracting Officer without evidence of the Contractor's
approval may be returned for resubmission.  The Contracting Officer will
indicate an approval or disapproval of the shop drawings and if not approved as
submitted shall indicate the Government's reasons therefor.  Any work done
before such approval shall be at the Contractor's risk and subject to
disallowance of costs.  Approval by the Contracting Officer shall not relieve
the Contractor from responsibility for any errors or omissions in such
drawings, nor from responsibility for complying with the requirements of this
contract, except with respect to variations described and approved in
accordance with (f) below.

                      (f) If shop drawings show variations from the contract
requirements, the Contractor shall describe such variations in writing,
separate from the drawings, at the time of submission.  If the Contracting
Officer approves any such variation, the Contracting Officer shall issue an
appropriate contract modification, except that, if the variation is minor or
does not involve a change in price or in time of performance, a modification
need not be issued.

                      (g) The Contractor shall submit to the Contracting
Officer for approval four copies (unless otherwise indicated) of all shop
drawings as called for under the various headings of these specification. Three
sets (unless otherwise indicated) of all shop drawings, will be retained by the
Contracting Officer and one set will be returned to the Contractor.  Upon
completing the work under this contract the Contractor shall furnish a complete
set of all shop drawings as finally approved.  These drawings shall show all
changes and revisions made up to the time the equipment is completed and
accepted.

                             (2) The Contractor shall be responsible for loss
or destruction of, or damage to, the Government property provided under this
contract (including expenses incidental to such loss, destruction, or damage)-
                                  (i) That results from a risk expressly
required to be insured under this contract, but only to the extent of the
insurance required to be purchased and maintained or to the extent of insurance
actually purchased and maintained, whichever is greater;

                                  (ii) That results from a risk that is in fact
covered by insurance or for which the Contractor is otherwise reimbursed, but
only to the extent of such insurance or reimbursement;

 (iii) For which the Contractor is otherwise responsible under the express terms
                                                               of this contract;

                                  (iv) That results from willful misconduct or
lack of good faith on the part of the Contractor's managerial personnel; or

                                  (v) That results from a failure on the part
of the Contractor, due to willful misconduct or lack of good faith on the part
of the Contractor's managerial personnel, to establish and administer a program
or system for the control, use, protection, preservation, maintenance, and
repair of Government property as required by paragraph (e) of this clause.

                            (3)   (i) If the Contractor fails to act as
provided by subdivision (g)(2)(v) above, after being notified (by certified
mail addressed to one of the Contractor's managerial personnel) of the
Government's disapproval, withdrawal of approval, or non-acceptance of the
system or program, it shall be conclusively presumed that such failure was due
to willful misconduct or lack of good faith on the part of the Contractor's
managerial personnel.

                                  (ii) In such event, any loss or destruction
of, or damage to, the Government property shall be presumed to have resulted
from such failure unless the Contractor can establish by clear and convincing
evidence that such loss, destruction, or damage--

                                        (A) Did not result from the
Contractor's failure to maintain an approved program or system; or

                                        (B) Occurred while an approved program
or system was maintained by the Contractor.

                           (4) If the Contractor transfers Government property
to the possession and control of a subcontractor, the transfer shall not affect
the liability of the Contractor for loss or destruction of, or damage to, the
property as set forth above.  However, the Contractor shall require the
subcontractor to assume the risk of, and be responsible for, any loss or
destruction of, or damage to, the property while in the subcontractor's
possession or control, except to the extent that the subcontract, with the
advance approval of the Contracting Officer, relieves the subcontractor from
such liability.  In the absence

<PAGE>   51
                                                                   Page 51 of 78


of such approval, the subcontract shall contain appropriate provisions
requiring the return of all Government property in as good condition as when
received, except for reasonable wear and tear or for its use in accordance with
the provisions of the prime contract.

                           (5) The Contracting Officer shall notify the
Contracting Officer upon loss or destruction of, or damage to, Government
property provided under this contract, with the exception of low value property
for which loss, damage, or destruction is reported at contract termination,
completion, or when needed for contract performance.  The Contractor shall take
all reasonable action to protect the Government property from further damage,
separate the damaged and undamaged Government property, put all the affected
Government property in the best possible order, and furnish to the Contracting
Officer a statement of-
                                (i) The lost, destroyed, or damaged Government 
property;

                                (ii) The time and origin of the loss, 
destruction, or damage;

                                (iii) All known interests in commingled 
property of which the Government property is a part; and

                        (iv) The insurance, if any, covering any part of or
interest in such commingled property.

                           (6) The Contractor shall repair, renovate, and take
such other action with respect to damaged Government property as the
Contracting Officer directs.  If the Government property is destroyed or
damaged beyond practical repair, or is damaged and so commingled or combined
with property of others (including the Contractor's) that separation is
impractical, the Contractor may, with the approval of and subject to any
conditions imposed by the Contracting Officer, sell such property for the
account of the Government.  Such sales may be made in order to minimize the
loss to the Government, to permit the resumption of business, or to accomplish
a similar purpose.  The Contractor shall be entitled to an equitable adjustment
in the contract price for the expenditures made in performing the obligations
under this subparagraph (g)(6) in accordance with paragraph (h) of this clause.
However, the Government may directly reimburse the loss and salvage
organization for any of their charges.  The Contracting Officer shall give due
regard to the Contractor's liability under this paragraph (g) when making any
such equitable adjustment.

                           (7) The Contractor shall not be reimbursed for, and
shall not include as an item of overhead, the cost of insurance or of any
reserve covering risk of loss or destruction of, or damage to, Government
property, except to the extent that the Government may have expressly required
the Contractor to carry such insurance under another provision of this
contract.

                           (8) In the event the Contractor is reimbursed or
otherwise compensated for any loss or destruction of, or damage to, Government
property, the Contractor shall use the proceeds to repair, renovate, or replace
the lost, destroyed, or damaged Government property or shall otherwise credit
the proceeds to, or equitably reimburse, the Government, as directed by the
Contracting Officer.

                           (9) The Contractor shall do nothing to prejudice the
Government's rights to recover against third parties for any loss or
destruction of, or damage to, Government property.  Upon the request of the
Contracting Officer, the Contractor shall, at the Government's expense, furnish
to the Government all reasonable assistance and

                                                                   Page 52 of 78


cooperation (including the prosecution of suit and the execution of instruments
of assignment in favor of the Government) in obtaining recovery.  In addition,
where a subcontractor has not been relieved from liability for any loss or
destruction of, or damage to, Government property, the Contractor shall enforce
for the benefit of the Government  the liability of the subcontractor for such
loss, destruction, or damage.

                 (h) Equitable adjustment.  When this clause specifies an
equitable adjustment, it shall be made to any affected contract provision in
accordance with the procedures of the Changes clause.  When appropriate, the
Contracting Officer may initiate an equitable adjustment in favor of the
Government.  The right to an equitable adjustment shall be the Contractor's
exclusive remedy.  The Government shall not be liable to suit for breach of
contract for--

                           (1) Any delay in delivery of Government-furnished
property;

                           (2) Delivery of Government-furnished property 
in a condition not suitable for its intended use;

                           (3) A decrease in or substitution of Government-
furnished property; or

                           (4) Failure to repair or replace Government
property for which the Government is responsible.

                 (i) Final accounting and disposition of Government property.
Upon completing this contract, or at such earlier dates as may be fixed by the
Contracting Officer, the Contractor shall submit, in a form acceptable to the
Contracting Officer, inventory schedules covering all items of Government
property not consumed in performing this contract or delivered to the
Government.  The Contractor shall prepare for shipment, deliver f.o.b. origin,
or dispose of the Government property as may be directed or authorized by the
Contracting Officer.  The net proceeds of any such disposal shall be credited
to the cost of the work covered by this contract or paid to the Government as
directed by the Contracting Officer.  The foregoing provisions shall apply to
scrap from Government property; provided, however, that the Contracting Officer
may authorize or direct the Contractor to omit from such inventory schedules
any scrap consisting of faulty castings or forgings or of cutting and
processing waste, such as chips, cuttings, borings, turnings, short ends,
circles, trimmings, clippings, and remnants, and to dispose of such scrap in
accordance with the Contractor's normal practice and account for it as a part
of general overhead or other reimbursable costs in accordance with the
Contractor's established accounting procedures.

                 (j) Abandonment and restoration of Contractor premises.
Unless otherwise provided herein, the Government-

                           (1) May abandon any Government property in place, at
                           which time all
obligations of the Government regarding such abandoned property shall cease;
and

                           (2) Has no obligation to restore or rehabilitate the
Contractor's premises under any circumstances (e.g., abandonment, disposition
upon completion of need, or contract completion).  However, if the
Government-furnished property (listed in the Schedule or specifications) is
withdrawn or is unsuitable for the intended use, or if other Government
property is substituted, then the equitable adjustment under paragraph (h) of
this clause may properly include restoration or rehabilitation costs.

                 (k) Communications.  All communications under this clause
shall be in writing.

Contracting Officer and shall be built with labor and materials furnished by the
Contractor without expense to the Government.  The temporary buildings and
utilities shall remain the property of the Contractor and shall be removed by

consent of the Contracting Officer, the buildings and utilities may be abandoned
and need not be removed.

                 (c) The Contractor shall, under regulations prescribed by the

Contracting Officer.  The Contractor shall describe these shipments in the
following format:

the Government will reject and return it to the Contractor as an improper
invoice for the purposes of the Prompt Payment clause of this contract.  In the

performance of this contract, the Contracting Officer is entitled to equitably
adjust the contract, based on the unauthorized use.

paragraph (g), in all subcontracts under this contract which exceed the

5352.243-9001    ADVANCE CHANGE ADJUSTMENT AGREEMENTS
                 (AFMC) (JUL 1997)

                 (a)  Purpose.  This clause establishes a procedure by which
the parties agree to change this contract per the Changes clause of this
contract without an equitable adjustment to the contract price.  The parties
agree that each change not exceeding $5,000.00 [or as otherwise negotiated at
the delivery order level], which also does not affect the contract delivery or
performance schedules or any other contract clause, ter~m or condition shall be
a change having no effect on the contract price.  For cost contracts, there
will be no fee adjustment for each change not exceeding $5.,000.00 [or as
otherwise negotiated at the delivery order level], which does not affect
contract delivery or performance, or any contract clause, term or condition.

                 (b)  Procedure.  When it is proposed to make a change under
the Changes clause and both parties agree that such a change shall require no
equitable adjustment as contemplated by paragraph (a) of this clause, the
Contractor shall submit a written

proposal or offer to accomplish the proposed change without an equitable
adjustment.  If the Contracting Officer determines no adjustment is necessary,
the Contractor's proposal may be accepted by issuing a unilateral modification
using an SF Form 30 or AFMC Form 702, Amendment of Solicitation/Modification of
Contract.  The modification shall (1) be issued under the Changes clause; (2)
cite this clause; (3) reference the Contractor's proposal or offer; and (4)
direct the changes to be made.  The issuance of the modification shall
constitute acceptance of the Contractor's proposal or offer, shall be binding
on both parties, and shall be a full, complete and final settlement for the
directed changes.

5352.243-9002    NOT-TO-EXCEED/NOT-LESS-THAN AGREEMENTS
                 (AFMC) (JUL 1997)

          (a) Prior to the issuance of a change order under this
firm-fixed-price contract, the Contractor shall promptly furnish, upon request
of the Contracting Officer, written agreement as to the maximum (in the case of
an increase) adjustments to the contract price and/or in the delivery schedule
(or time of performance), caused by the change.

* Or in the case of a reduction, a not-less-than amount for the price.

          (b) The Contracting Officer shall also solicit such agreement on
limitations to the adjustments or to any other contract requirements which may
be subject to equitable adjustment by reason of the change. Any such written
agreement shall then be cited in the change order and, upon its issuance, shall
be a binding part of the contract.  In no event shall the definitive equitable
adjustment exceed the delivery schedule (or time of performance) adjustments so
established.  All costs associated with the change order shall be segregated
from other contract costs until the change order has been definitized.  Except
with respect thereto, nothing contained herein shall affect the rights of the
parties to an equitable adjustment by reason of the change, pursuant to the
"Changes" clause.

ALTERNATE III (AFMC) (JUL 1997).

          (a) Prior to the issuance of a change order under this contract, the
Contractor shall promptly furnish, upon request of the Contracting Officer,
written agreement as to the maximum (in the case of an increase) adjustments* to
be made in both the estimated cost and fixed fee, and/or in the delivery
schedule (or time of performance), caused by the change.

cost and the fixed fee.

Letter Contracts), do not apply to the following subcontracts, which were

This clause shall in no way relieve the Contractor of any responsibility for
performing this contract; shall not create any obligation of the Government to,

or claim of the Government under this contract; and shall not constitute a
determination of the acceptability of the subcontract terms or conditions or
the allowability of any costs under this contract.  Any request for consent to

cognizant Administrative Contracting Officer as required by the "Subcontracts"
clause.

Base support shall be provided by the Government to the Contractor in

requirements of this clause shall release the Government, without prejudice,

warranted, and if the Contractor has complied with the requirements of this
clause, an equitable adjustment shall be made if the Government fails to
provide base support by the date(s) required.

          (a) Base support includes Government-controlled working space,
material, equipment, services (including automatic data processing), or other
support (excluding use of the Defense Switched Network (DSN)) which the
Government determines can be made available at, or through, any Air Force

the possession of the Contractor, provided through the base support clause,
shall be used and managed in accordance with the Government Property clauses.

          (b) The Air Force installations providing the support shall be listed
in subparagraph (e), and the Government support to be furnished by each
installation under this contract shall be listed in subparagraph (f).

          (c) Unless otherwise stipulated in the contract schedule, support

cognizant CAO) inadequacies, defective Government-Furnished Property (GFP), or
nonavailability of support stipulated by the contract schedule, together with a

requirement and the method by which it shall be fulfilled (e.g., purchase,
rental, lease, GFP, etc.).  Facilities shall not be purchased under this clause.
Additionally, the Contractor (or authorized representative) shall not purchase,
or otherwise furnish any base support requirement provided by the clause (or

Officer regarding the price, terms, and conditions of the proposed purchase, or
approval of other arrangements.

          (e) Following are installations where base support will be provided
(insert list of installations).

          (f) The Government support to be furnished under this contract is

time-and-materials, or labor hour contract, the Contractor agrees that in the
performance of this contract or any major subcontract no direct or indirect
costs for property will be incurred if the Government determines that property
is available at, or through any Air Force installation where this contract shall
be performed.  Only the prior written approval of the Contracting Officer can
relieve the Contractor from this restriction.

APPLICABLE TO COSTREIMBURSEMENT DELIVERY ORDER EFFORTS.


5352.216-9003    AWARD FEE (AFMC) (JUL 1997)

(a) In addition to the Zero percent (0%) base fee set forth in H-004 of this
contract, the Contractor may earn an award fee of up to six percent (6%) of the
estimated cost on each delivery order on the basis of performance during the
evaluation periods, and in the amount specified in the award fee plan.

(b) Monitoring of Performance.  The Contractor's performance will be
continually monitored by the performance monitor whose findings are reported to
the Award Fee Review Board (AFRB).  The AFRB recommends an award fee to the Fee
Determining Official (FDO) who makes the final decision of the award fee amount
paid based on the Contractor's performance during the award fee evaluation
period.

(c) Award Fee Plan.  The evaluation criteria and associated grades are
specified in the award fee plan.  The evaluation periods with the associated
award fee pool amounts and performance criteria with associated percentages of

award fee plan if the Contractor is provided written notification by the
Contracting Officer before the start of the upcoming evaluation period.
Changes affecting the current evaluation period must be by bilateral agreement.

(e) Self-Evaluation.  The Contractor may submit to the Contracting Officer,
within five (5) working days after the end of each award fee evaluation period,
a brief written self-evaluation of its performance for that period.  This
self-evaluation shall not exceed (insert number of pages) pages.  This
self-evaluation will be used in the AFRB's evaluation of the Contractor's
performance during this period.

(f) Disputes.  All FDO decisions regarding the award fee, including but not
limited to, the amount of the award fee, if any; the methodology used to
calculate the award fee; the calculation of the award fee; the Contractor's
entitlements to the award fee; and the nature and success of the Contractor's
performance, shall not be subject to the "Disputes" clause nor reviewed by any
Board of Contract Appeal (BCA), court, or other judicial entity.

5352-228-9000    PAYMENT AND PERFORMANCE BONDS
                 REQUIREMENTS FOR FIXED-PRICE
                 SUBCONTRACTS (AFMC) (JUL 1997)

          (a) Pursuant to DFARS 228.102-1, the requirement for payment and
performance bonds is waived for cost-reimbursement contracts.  In the
performance of this cost reimbursement contact, it is expected that fixed-price
subcontracts for construction or demolition efforts will be used. Therefore, for
fixed-price construction subcontracts greater than $25,000 the prime Contractor
is required to obtain from each construction subcontractor: (1) A payment bond
in favor of the prime Contractor sufficient to pay material and labor costs;
and, (2) A performance bond in an equal amount, if available at no additional
cost.

          (b) When evidence of a performance bond and a payment bond with good
and sufficient surety is required, such evidence shall be delivered to the
Contracting Officer within 10 calendar days after award of the respective
subcontract by the prime Contractor.

          (c) All bonds, including any necessary reinsurance agreements and
construction permits, must be received by the Contracting Officer before a
notice to proceed with the work is issued.

          (b) When evidence of a performance bond and a payment bond with good
and sufficient surety is required, such evidence shall be delivered to the
Contracting Officer within 10 calendar days after award of the respective
subcontract by the prime Contractor.

          (c) All bonds, including any necessary reinsurance agreements and
construction permits, must be received by the Contracting Officer before a
notice to proceed with the work is issued.

                  (a) Pursuant to DFARS 228.102-1, the requirement for payment
and performance bonds is waived for cost-reimbursement contracts.  In the
performance of this cost-reimbursement contract, it is expected that fixed price
subcontracts for construction or demolition efforts will be used. Therefore, for
fixed price construction subcontracts greater than $25,000, the Contractor is
required to obtain from each construction subcontractor:

                       (1) A payment bond in favor of the prime contractor
sufficient to pay material and labor costs; and,

                       (2) A performance bond in an equal amount, if available
at no additional cost.

                 (b) When evidence of a performance bond and a payment bond
with good and sufficient surety is required, such evidence shall be delivered
to the Contracting Officer within 10 calendar days after award of the
respective subcontract by the prime contractor.

                 (c) All bonds, including any necessary reinsurance agreements
and construction permits must be received by the Contracting Officer before a
notice to proceed with the work will be issued.


1.  DFARS CLAUSES IN FULL TEXT

                 THE FOLLOWING FULL TEXT CLAUSE SHALL BE APPLICABLE ONLY TO
FIXED-PRICE DELIVERY ORDER EFFORTS.

252.232-7007     LIMITATION OF GOVERNMENT'S OBLIGATION (AUG)

                 (a) Contract line item 0001 is incrementally funded.  For this 
item, the sum of $________________________ [TBD at each Delivery Order] of the 
total price is presently available for payment and allotted to this contract.
An allotment schedule is set forth in paragraph (i) of this clause.

                      (b) For item(s) identified in paragraph (a) of this 
clause, the Contractor agrees to perform up to the point at which the total
amount payable by the Government, including reimbursement in the event of
termination of those item(s) for the Government's convenience, approximates the
total amount currently allotted to the contract.  The Contractor will not be
obligated to continue work on those item(s) beyond that point.  The Government
will not be obligated in any event to reimburse the Contractor in excess of the
amount allotted to the contract those item(s) regardless of anything to the
contrary in the clause entitled "Termination for Convenience of the Government."
As used in this clause, the total amount payable by the Government in the event
of termination of applicable contract line item(s) for convenience includes
costs, profit, and estimated termination settlement costs for those item(s).

                      (c) Notwithstanding the dates specified in the allotment
schedule in paragraph (i) of this clause, the Contractor will notify the
Contracting Officer in writing at least ninety days prior to the date when, in
the Contractor's best judgment, the work will reach the point at which the
total amount payable by the Government, including any cost for termination for
convenience will approximate 85 percent of the total amount then allotted to
the contract for performance of the applicable item(s).  The notification will
state (1) the estimated date when that point will be reached and (2) an
estimate of additional funding, if any, needed to continue performance of
applicable line items up to the next scheduled date for allotment of funds
identified in paragraph (i) of this clause, or to a

mutually agreed upon substitute date.  The notification will also advise the
Contracting Officer of the estimated amount of additional funds that will be
required for the timely performance of the item(s) funded pursuant to this
clause, for a subsequent period as may be specified in the allotment schedule
in paragraph (i) of this clause or otherwise agreed to by the parties.  If
after such notification additional funds are not allotted by the date
identified in the Contractor's notification, or by an agreed substitute date,
the Contracting Officer will terminate any item(s) for which additional funds
have not been allotted, pursuant to the clause of this contract entitled
"Termination for Convenience of the Government."

          (d) When additional funds are allotted for continued performance of
the contract line item identified in paragraph (a) of this clause, the parties
will agree as to the period of contract performance which will be covered by the
funds.  The provisions of (b) through (d) of this clause will apply in like
manner to the additional allotted funds and agreed substitute date, and the
contract will be modified accordingly.

                      (e) If, solely by reason of failure of the Government to
allot additional funds, by the dates indicated below, in amounts sufficient for
timely performance of the contract line item identified in paragraph (a) of
this clause, the Contractor incurs additional cost or is delayed in the
performance of the work under this contract, and if additional funds are
allotted, an equitable adjustment will be made in the price or prices
(including appropriate target, billing, and ceiling prices where applicable) of
the items or in the time of delivery or both.  Failure to agree to any such
equitable adjustment hereunder will be a dispute concerning a question of fact
within the meaning of the clause of this contract entitled "Disputes."

          (f) The Government may at any time prior to termination allot
additional funds for the performance of the contract line item identified in
paragraph (a) of this clause.

          (g) The termination provisions of this clause do not limit the rights
of the Government under the clause entitled "Default." The provisions of this
clause are limited to the work on and allotment of funds for the contract line
items set forth in paragraph (a) above.  This clause no longer applies once the
contract is fully funded except with regard to the rights or obligations of the
parties concerning equitable adjustments negotiated under paragraphs (d) and (e)
of this clause.

          (h) Nothing in this clause affects the rights of the Government to
terminate this contract pursuant to the clause of this contract entitled
"Termination for Convenience of the Government."

          (i) The parties contemplate that the Government will allot funds to
this contract in accordance with the following schedule:

          On execution of contract                                            $
          (month) (day), 199x [to be determined on each delivery order]       $
          (month) (day), 199y [to be determined on each delivery order]       $
          (month) (day), 199z [to be determined on each delivery order]       $

1.0  SCOPE

This basic contract Statement of Work (SOW) defines the scope of remedial
actions that may be carried out under a Delivery Order (DO) at various worldwide
locations. This SOW encompasses the range of methods and technologies supporting
activities necessary to remedy site conditions in accordance with technical and
regulatory requirements. These sites may require proven and/or innovative
technologies and methods to accomplish the work. Innovative technologies and
methods may include those listed in the reports of the Superfund Innovative
Technology Evaluation (SITE) Program published by the US Environmental
Protection Agency (EPA), and those developed under sponsorship of the US Air
Force.

The work to be performed under this basic contract SOW requires environmental
remediation of sites located on US Government (primarily Air Force)
installations as well as any other worldwide site for which the Air Force Center
for Environmental Excellence (AFCEE) customers have responsibility.

The Contractor shall function as an integral team member in support of the AFCEE
mission. These expectations include efficient management of DOs including
accurate, on-time submittals of contract deliverables and timely identification
and solution of impediments to successful project execution. Technical
requirements include early involvement in the process to allow for the
development of the most cost-effective and technically sound remedy. AFCEE will
rely on the contractor's expertise in recognizing and addressing problematic
issues and successful execution of each DO. The Contractor shall perform all
work in accordance with federal, state, and local statutes and regulations.
Remedies shall conform to environmental permit or decision document
requirements.

1. 1  Background

The Air Force is committed to effective compliance and stewardship activities
for Air Force lands, including Government Owned-Contractor Operated (GOCO)
facilities, to provide access to the air, land, and water needed to maintain and
improve Air Force mission capability. This commitment is accomplished by
complying with federal, state, and local environmental statutes and regulations.
Compliance is accomplished under many Air Force programs, several of which have
been implemented to investigate conditions at past hazardous waste disposal and
spill sites and select remedial actions for those sites that pose a threat to
human health and welfare and to the environment. It is the expanded mission of
the AFCEE, as a national asset to the US Government, to provide these same
services and capabilities to other agencies and AFCEE customers, in addressing
similarly aggressive national and international remediation programs, as
requested.

3.1              Management, Planning, and Reporting Requirements

The Contractor shall plan project activities and develop, implement, and
maintain schedules of project events, describe the status of resources, report
on activity and progress toward accomplishing objectives, and document the
results of project efforts for each DO.

3.1.1            Integrated Master Schedule

The Contractor shall prepare a work breakdown structure (WBS) or equivalent task
breakdown for each DO. The breakdown structures shall be used to report schedule
status. The Contractor shall provide an Integrated Master Schedule for the task
specific DO. (Contract Data Requirements Lists [CDRLS] B001, B002)

3.1.2            Project Schedules

The Contractor shall prepare a computer generated network analysis which is a
detailed task plan for all tasks for approval by the COR. The network analysis
(e.g., GANTT, PERT, CPM) shall be in the form of a progress chart of suitable
scale to indicate appropriately the percentage of work scheduled for completion
by any given date during the period of the DO. The Network Analysis shall show
both serial and parallel sub-tasks leading to a deliverable product/report. Show
early and late start and completion date with float. (CDRL B003)

3.1.3            Cost Performance Report
