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;
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.

     The statements in this report,  including  statements under the headings of
Business,  Legal Proceedings,  and Management's  Discussion and Analysis and the
attached  financial  statements,  reflect  the  business  lines and two  month's
financial results of Science  Management  Corporation  ("SMC").  On May 2, 1997,
Versar,  Inc.  ("Versar"  or the  "Company")  purchased a majority of the common
shares  and  all of the  outstanding  preferred  shares  of  SMC as  more  fully
described  below.  As a  result,  the SMC  revenue  for the last two  months  of
Versar's fiscal year is included in Versar's financial  statements as a majority
owned subsidiary.  In addition,  because SMC has negative retained earnings, the
entire net income of SMC for May and June of 1997 is also  included  in Versar's
results.  This inclusion will continue until the negative  retained earnings are
eliminated and then,  until the closing of the merger  described  below,  Versar
will  account  for  SMC's  earnings  on an equity  basis of its 53.5%  ownership
interest in SMC's common stock. On July 27, 1997, SMC and Versar entered into an
Agreement  and Plan of Merger  which is  subject  to SMC  stockholder  approval.
Versar  believes that the merger and, thus, the acquisition of the remaining SMC
outstanding  common stock,  will occur during the second  quarter of fiscal year
1998.

     Versar is a diversified  international  professional services firm, helping
clients in the  private  and public  sectors  enhance  their  performance  while
reducing costs and achieving environmental excellence.  Versar combines science,
technology, and people with specialized skills to design and implement programs.
In addition, we design systems,  facilities,  and equipment to improve operating
performance,  conserve resources,  reduce emissions and waste generation,  which
ultimately increase  productivity and profitability,  protects worker health and
safety and our environment.

     On May 2, 1997,  pursuant  to a Stock  Purchase  Agreement  dated April 30,
1997,  Versar  purchased  from  Imperial  Capital  Worldwide  Partners,  L.P., a
Delaware limited partnership  ("Imperial")  1,070,000 shares common stock of SMC
(representing  53.5% of the issued and outstanding common stock of SMC), 100% of
the  issued  and  outstanding  preferred  stock of SMC and  certain  options  to
purchase 350,000  additional  shares of SMC common stock for a purchase price of
$2,790,000 paid in cash. As additional  consideration  for such stock purchases,
the Company paid certain legal fees  incurred by Imperial and its  affiliates in
connection  with the stock  purchase  and  other  matters  related  to SMC in an
aggregate  amount  of  $80,000.  The  purchase  price  paid by the  Company  was
determined by the Company's bid exceeding another competitive bid.

     Versar's four major business  areas are: (1)  environmental  services;  (2)
management services; (3) facilities and information management services; and (4)
engineering,  design, and construction services to the process industries. As is
indicated  below,  certain of these business areas have developed as a result of
the integration of

                                        2

<PAGE>

SMC into the Versar  corporate  group and represent a combination of traditional
services of SMC with Versar's traditional services offerings.

     Environmental  Services include the full range of scientific,  engineering,
and  construction  services to address the  prevention,  detection,  management,
control,  and cleanup of toxic substances and hazardous waste in the environment
and constituted the primary  business line of Versar prior to the acquisition of
SMC.  Versar  emphasizes  innovation in process and  technology  application  to
achieve  better  results  more  quickly  and at  less  cost  in  today's  highly
competitive market.  Versar's  Environmental Services Group works in partnership
with  government  and  industry by becoming an involved  member of our  clients'
organization.  We focus on a client-centered approach that builds relationships,
sets priorities,  ensures proper  allocation and control of resources,  supports
and  encourages  synergistic  activities  among  the  various  elements  of  the
organization,  and  monitors  results.  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,  better manage the spectrum of  environmental  compliance,  and apply
innovative and cost-effective  approaches to remediation or corrective action of
past problems in our environment.

     Today's  environmental  challenges require an integrated  multidisciplinary
team actively  assisting  clients in making informed  decisions and implementing
them at the least cost. These challenges are driven by:

     o    A 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.

     o    A Increased  emphasis on compliance  management and  recognition  that
          pollution prevention and waste minimization are necessary parts of the
          long-term sollution to local and national environmental challenges.

     o    A  Competition  for  limited  resources  and a need for new and better
          technology to achieve pollution  prevention and remediation goals more
          cost effectively.

Versar  helps its clients  meet these  challenges  as a  full-service  firm that
emphasizes:

Strategic  Planning  and  Pollution  Prevention.  These are  Versar's  trademark
environmental  services,  capitalizing  on its combined  strengths in regulatory
policy,  risk  assessment,   information  management,   pollution  control,  and
treatment technology, which emphasize pollution prevention. This service is also
fully integrated with and is part of Versar's Management  Services.  Versar also
provides  nationally  recognized  services  in the  area  of  natural  resources
management and ecological studies.

Total Compliance  Management  (TCM). TCM is a strategic  approach and process of
continuous  improvement  that permits  senior  management to view  environmental
compliance expenditures as a business investment thus creating an "Environmental
Balance Sheet." Versar consults at the highest levels of industry and government
where policy decisions are made. Versar supports its clients in implementing new
programs  and  approaches  as well as  managing  current  programs  on-site  and
outsourcing  through its Facilities and  Information  Services.  Versar has also
positioned  itself  to  be  a  leader  in  marketing  services  related  to  the
environmental  standards by the  International  Organization for Standards,  ISO
14000. A further  enhancement to the ISO 9000 quality standards  promulgated and
widely  adopted   several  years  ago,  ISO  14000  will   establish   voluntary
environmental compliance standards for the international business community.

Corrective/Remedial  Action.  Versar  provides  the full  range of  services  in
remedial/corrective   action   from   site   investigation,   remedial   design,
construction,  and operation and maintenance (O&M) of remedial systems. More and
more clients are asking how their project can be accomplished  more efficiently.
Versar  emphasizes   innovative   solutions  to  such  problems  as  groundwater
remediation. For example, Versar successfully demonstrated the

                                        3

<PAGE>

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.  Versar also brings to its clients a new alternative to conventional
remedial technologies, known as Bio-Injection. This method of remediation allows
the concurrent treatment of soils and groundwater with a mixture of bacteria and
nutrients.  This process typically requires a one-time treatment,  with positive
results  achieved within months instead of years at less cost than  conventional
treatment methods.

     Versar is applying these and other technologies as it focuses more and more
on emerging  opportunities in the  redevelopment of industrial  properties under
EPA and States' Brownfields programs. Versar has established alliances with real
estate  and  investment  firms to help  clients  bring  new  life to  abandoned,
contaminated sites in prime real estate areas.

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

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

     Personal  Protection  Equipment  (PPE)/ChemDemil.  A specialty area for the
Company is our Chemical Surety  Laboratory and our 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 third 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
an  individual  cooling  system  for the  worker.  GEOMET  is also a  commercial
supplier to remedial action  contractors  and others of PPE specially  qualified
for chemical protection.  Driven in part by the Sarin attack on the Tokyo subway
in 1995,  Versar has  significantly  expanded  offering  its  services to local,
State,  and  foreign  governments  in support of  counter-terrorism.  Management
believes the  opportunities  for commercial  application  will continue to grow.
GEOMET also has an energy services practice,  which involves energy auditing and
energy  conservation  services  to a variety of clients.  This  service is fully
integrated with and part of utility support services.

     Management  Services  include  strategic  planning and the  development and
implementation  of  comprehensive  programs to help  clients  optimize  resource
utilization to enhance  operating  performance,  improve the quality of products
and services, achieve sustainable environmental compliance as well as maintain a
competitive  advantage  and  return on  investment  goals.  Versar's  Management
Services Group assists its clients in identifying  areas requiring  improvement,
provides specific recommendations,  develops programs, and actively participates
in their  implementation.  Using a "Total Enterprise"  approach to productivity,
the Management Services Group helps clients

                                        4

<PAGE>

improve   profitability  by  more  effectively  employing  all  their  resources
(personnel,  materials,  equipment,  facilities,   organization,   science,  and
technology)  in day-to-day  operations  and adapting to ever  changing  business
conditions. A key focus is helping clients integrate environmental,  health, and
safety  performance into facility  operation in a way that reduces operating and
overhead  costs,  emissions  and waste  generation,  and the need for  expensive
"end-of-pipe"  control technology.  Key service areas of the Management Services
include:

     o    Profit Improvement and Sustainability
     o    Team Building and Improved Management Effectiveness
     o    Organizational Optimization
     o    Quality Improvement/Management
     o    Resources Management and Conservation
     o    Technology Management
     o    Risk Management
     o    Strategic Environmental Management
     o    Business Process Reengineering
     o    Logistics Support
     o    Documentation Reduction
     o    Facility O&M Performance Benchmarking and Improvement

     Versar has provided  management  consulting and program support services to
both  government and industry.  Versar has  significantly  expanded this service
offering with the  acquisition of SMC, one of whose core businesses is providing
senior  level  strategic  planning  and  management  consulting  services.   The
Management  Services  Group which  employs a variety of  proprietary  analytical
techniques   including  the   Work-Factor(R)   System,   a  widely   recognized,
predetermined  elemental  time system  developed  by SMC and used to measure the
human work component of highly-repetitive  manufacturing processes. SMC has also
developed other systems and techniques  designed to improve the  productivity of
administrative,   support,  and  professional  personnel  in  a  wide  range  of
functions.

     Facilities  and  Information  Management  Services  include a full range of
utility   infrastructure   (energy,   water,   wastewater)   support   services,
environmental  compliance  management  functions,  information  management,  and
business  recovery  services.  Versar provides  consulting  services and on-site
support with  dedicated  personnel,  and takes  responsibility  for and provides
specific services on an outsourcing basis.

     Versar provides utility infrastructure support services in three areas:

     o    A Consulting and  management  support in  evaluating,  procuring,  and
          implementing  alternative  options  for the  optimization  of  utility
          operations  and  maintenance   services.  A  key  focus  is  improving
          compliance  and the quality of utility  services,  while  reducing the
          costs of these services  through  better use of available  technology,
          training,  and  development  of  operating  personnel  and  innovative
          approaches to project financing.

     o    A Contract  operations  or  outsourcing  where  Versar  takes over the
          operations and maintenance of our clients' utility infrastructure.

     o    A Privatization  initiatives where Versar designs,  builds,  operates,
          and maintains a client's utility infrastructure needs.

Versar also offers  services to take over existing  utility assets on a purchase
or lease basis.  Versar will deliver the required  services on a contract  basis
and will assume responsibility for permitting and ensuring regulatory compliance
for all systems it manages whether  performed on a outsourcing  basis or under a
privatization initiative.

     Versar provides  environmental  compliance management services both on-site
and on an  outsourcing  basis to meet our  clients'  needs as they  continue  to
restructure, reduce their overhead costs, and improve productivity. Industry and
government are using new  technology to improve  environmental  performance  and
bolster  profits.  In doing so,  companies are turning to solutions that address
pollution prevention as an integral part of plant operations and control. Versar
brings  its  clients  knowledge  and  experience  in  the  application  of  such
technology.  An  integral  part  of  Versar's  services  is the  application  of
environmental  health  and  safety  management  information  systems  in helping
clients make more informed decisions.  Having long recognized the limitations of
regulatory driven environmental, health, and safety programs, Versar has focused
on the economic benefits of an alternative approach to environmental management.
This approach  places the  customer's  business  objectives at the center of the
decision-making process, and then addresses the environmental, health and safety
issues in such a way that they complement  those objectives while complying with
the regulations. Beyond regulatory compliance, this approach challenges Versar's
expertise  to develop and  implement  alternatives  that  enhance  the  client's
productivity  and reduce  the unit costs of  operations.  Versar  will  tailor a
program to suite a client's  needs as part of its  management  services and then
implement it through on-site support or on an outsourcing basis, as required.

     Versar's Business  Information  Systems ("BIS") services,  operated through
SMC, include systems support in Facilities  Management,  Business Recovery,  and
Professional Support Services.  Versar offers clients the full range of services
in managing,  staffing,  and operating data processing centers,  operations,  or
specific functions in accordance with client specifications.  Services performed
and functions  managed include data entry,  tape handling,  library  management,
maintenance,  and systems development.  Under multi-year  subcontracts from IBM,
Versar's BIS group currently  manages data centers in Connecticut and Tennessee,
performing a variety of activities for clients in several  industries.  With low
overhead and highly skilled  management,  Versar's BIS group offers  outsourcing
services at significantly  lower costs than larger  competitors.  The facilities
management   operations  of  BIS  have  built  an  excellent   service   record,
consistently  achieving  performance  reliability  targets  well  in  excess  of
contract requirements.

     In the business recovery area, Versar's BIS group offers a complete menu of
services  covering all aspects of business  continuation and recovery  services.
Through its highly qualified staff and consultants,  the BIS  professionally and
cost effectively  evaluates a client's business continuation and recovery needs,
creates specific  disaster recovery plans and programs,  and audits,  updates or
tests existing client plans for data backup and disaster  response.  Unlike many
of its competitors,  however,  BIS can also perform as a full solution provider,
offering  clients  online  backup  facilities  and  access  to  state of the art
alternate EDP operating  sites in its capacity as a business  partner to IBM and
other well known vendors. In this role, the BIS professionals  assist clients in
identifying and specifying  their needs,  arrange for backup or "hot sites" with
their  business  partners,  and support  implementation,  testing,  and periodic
update of the total business continuation or disaster recovery program.

     The professional  services support group included in the BIS group supports
all of its  services  and also  offers  clients  support in a variety of systems
needs,  including  network  and  internet  anti-virus  protection  programs  and
products.

Markets

     Versar's  markets are evolving in response to our clients'  changing needs,
and market  opportunities  are being driven by the  availability  of  technology
aimed at  productivity  improvement.  Versar has  significantly  diversified its
business over the last year,  primarily  through the  acquisition of SMC, with a
much greater emphasis on (1) environmental  services with particular emphasis on
redevelopment  of industry  properties  and  conversion  of  military  bases for
alternative uses, (2) facilities and information  management support services to
respond to our clients'  increasing need to make more informed  decisions and to
outsource  non-core  functions,  (3)  services to design,  build,  finance,  and
operate utility  infrastructure and facilities for the process  industries,  and
(4) management services to help industry and government  restructure and improve
their operating performance.

     Versar is on the cutting edge of a number of growth markets. These include:

     o    A  Industry's   continued  focus  on  productivity   improvement,   in
          particular  opportunities  internationally  and  with  Versar's  (SMC)
          multinational clients.

     o    A  Deregulation  of the energy  industry  presents  opportunities  for
          Versar (GEOMET) as a certified energy service provider contractor.

     o    A  Continued  growth in  consumption  of fossil  fuel and  demand  for
          improved  process  technologies  that prevent  pollution will increase
          worldwide  opportunities  for Versar (SMC McEver) in process  facility
          design and construction.

     o    A Government  /commercial  interest in expanding capability to respond

     Versar's  current client base,  including  clients of SMC, is well balanced
with 41 percent  industrial/commercial and 59 percent government.  Approximately
50 percent of Versar's  industrial/commercial  clients are in the petrochemical,
specialty chemical, and manufacturing industry. A major part of Versar's support
services to this client base  includes  the design and  construction  of process
facilities through SMC McEver, management services to multinationals and fortune
100 companies,  and environmental  management  services.  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 our 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.  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 cutting edge knowledge of
regulatory trends and their impacts.  Other Federal clients make up 6 percent of
our business and include the  Departments  of Energy and the  Interior,  Federal
Housing Authority,  and Intelligence Agencies.  State and local governments make
up 13 percent of Versar's business.

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,  our competitors are larger and have more
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
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, 1997, total backlog for Versar, including unfunded tasks and
orders,  was  approximately  $340  million,  as compared to  approximately  $325
million as of June 30, 1996.  Funded  backlog for Versar was  approximately  $41
million,  an increase of 28 percent compared to approximately  $32 million as of
June 30,  1996.  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, 1997,  Versar had  approximately  554 full-time  employees,  of
which  approximately 369 were engineers,  scientists,  and other  professionals.
Sixty percent of the Company's  professional  employees have a bachelors degree,
24% have a masters degree, and 3% 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 from Sarnia Corporation.  In June 1996, Versar reduced this leased space to
68,239 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, 1997,  the  Company had under  lease an  aggregate  of
approximately  227,000  square  feet  of  office  and  laboratory  space  in the
following  locations:  Springfield,  VA; Tempe,  AZ;  Alameda and Fair Oaks, CA;
Northglenn,  CO;  Miami,  FL;  Lombard,  IL; North Andover and  Burlington,  MA;
Hopkins,  MN;  Columbia,  Gaithersburg  and  Germantown,  MD;  Bridgewater,  NJ;
Cincinnati,  OH; Bristol and King of Prussia,  PA; San Antonio and Houston,  TX;
American Fork,  UT; France and England.  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

     On June 28, 1990, Gary R. Windolph, a former officer and director of Versar
Architects  & Engineers,  Inc.  ("VA&E",  formerly  ARIX  Corporation,  a former
subsidiary  of Versar,  which was merged  into Versar in July 1993) and a former
officer of Versar, filed an action in the District Court for the City and County
of Denver,  State of Colorado,  entitled Gary R.  Windolph v. ARIX  Corporation,
Versar,  Inc.,  et al.,  Case NO.  90-CV-7155.  On October  21,  1991,  the jury
returned  verdicts for Mr. Windolph on two defamation claims against the Company
and  awarded  him  damages in the  amount of  $200,000.  The jury also  returned
verdicts for Mr.  Windolph on certain of his statutory and common law securities
claims and awarded  damages in the amount of $1.00 each on all such  claims.  On
January 6, 1992,  the Court ruled that,  based upon the  evidence  presented  at
trial,  the  $200,000  awarded to Mr.  Windolph by the jury was  excessive  as a
matter of law and  ordered a new damage  trial on those  claims.  The retrial of
damages on these  claims  ended on October  21,  1992 with the jury  returning a
verdict against Versar in the total amount of $1,000,001  including $500,000 for
damages to Mr.  Windolph's  reputation  and $500,001  for personal  humiliation,
mental anguish and suffering.

     Versar promptly filed appropriate  post-trial  motions seeking either a new
trial or the entry of  judgment in an amount  less than the jury's  verdict.  On
January 10, 1993,  the Court  granted  Versar's  motion,  in part,  and gave the
plaintiff  the  choice of  accepting  the  entry of  judgment  in the  amount of
$75,000,  or retrying for a third time the amount of damages for the  defamation
claim.  The Court also decided,  as a matter of law, that the maximum amount Mr.
Windolph  could  recover was $250,000 due to a statutory  limit on  non-economic
damages.  At the same time, the Court ordered the parties to participate in good
faith in a mandatory  settlement  conference  to try to settle this matter.  The
parties  were  unable  to  reach a  settlement  as a  result  of the  settlement
conference  held in April,  1993, and the plaintiff  rejected the opportunity to
have judgment entered for $75,000 or proceed with a new trial. On June 16, 1993,
the trial court entered final judgment on all outstanding issues.

     Both parties appealed to the Colorado Court of Appeals. On May 25, 1995 the
Court issued its decision  affirming in part,  reversing in part and remanding a
part of the case to the trial  court.  The Court of Appeals  reversed  the trial
court's  dismissal of Windolph's  promissory  estoppel claim,  and remanded with
directions  for a new trial on that matter only.  The Court of Appeals  affirmed
the trial court as to all other matters,  including the trial court's refusal to
enter  judgment in  Windolph's  favor on the two jury  verdicts  relating to the
defamation  claim.  Both parties filed  motions for rehearing  with the Court of
Appeals, which were denied on August 10, 1995.

     In  September  1995,  Windolph  sought  review of this case by the Colorado
Supreme Court which was denied on February 20, 1996. The case proceeded to trial
on the  promissory  estoppel  claim only. A bench trial without jury was held on
January 27, 1997. On April 3, 1997, the Court entered judgment for Versar on the
promissory  estoppel claim rejecting Windolph arguments on the basis of Delaware
and  Colorado  law.  Alternatively,  the Court held that even if its judgment is
overturned on appeal, the maximum liability to Windolph would be $11,000. On May
23, 1997, the parties entered into a Stipulation of Dismissal  pursuant to which
Versar  agreed to  withdraw  its demand for court costs and  Windolph  agreed to
waive his right to appeal the trial court's decision,  thereby fully terminating
this litigation without any payment to Windolph.

     As part of the agreement to sell its  laboratory  assets and  operations to
Kemron  Environmental  Services,  Inc.  (Kemron) in July 1994,  Versar agreed to
refer its analytical laboratory work for a period of 48 months after the closing
date to Kemron subject to certain  limitations and exclusions  including federal
procurement  requirements  and the  ability  of Kemron to perform  the  required
services.  On July 31,  1996,  Kemron  filed an action in the  Circuit  Court of
Fairfax  County,   Commonwealth  of  Virginia,   entitled  Kemron  Environmental
Services, Inc. vs. Versar Laboratories,  Inc. and Versar, Inc., Law No. L154205.
Kemron alleged the defendants breached certain covenants that Versar would refer
laboratory work to Kemron in the Asset Acquisition Agreement and alleged damages
in the amount of not less than $3,000,000.

     Versar  responded  by  denying  the  allegations  and filed a  counterclaim
alleging various material breaches of the Asset Acquisition  Agreement by Kemron
and seeking a  declaratory  judgment  that  Kemron's  breaches  have  terminated
Versar's obligations under the Agreement.  On June 16, 1997, the parties entered
into a settlement  agreement  extending  and amending the right of Kemron to the
referral of analytical services from Versar.

     In June 1996,  Flintlock Ltd, a client of SMC McEver,  (a subsidiary of SMC
which is a majority  owned  subsidiary of Versar),  filed an action in the 165th
Judicial District Court of Harris County,  Texas, entitled Flintlock Ltd. v. SMC
McEver, Inc., Case No. 96-002700.  Flintlock alleged that SMC McEver negligently
failed to manage the construction of a citronella candle project and negligently
misrepresented  the  project's  cost.  Flintlock  asserts that it incurred  over
$700,000 in damages.  SMC McEver has  counterclaimed  for over $244,000 which it
claims is due under the  contract  between the  parties.  The parties have taken
certain  discovery  which  remains  ongoing.  The parties  have also  engaged in
discussions regarding possible mediation. SMC McEver has retained counsel and is
defending  this matter  vigorously.  The Company  does not expect the outcome of
this litigation to have a material adverse effect on its 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 1997.

Item 5.  Market for Registrant's Common Equity and Related Stockholder Matters

Common Stock

     The Company's  common stock is traded on the American  Stock  Exchange (the
"AMEX"),  under  the  symbol  VSR.  At  June  30,  1997,  the  Company  had  746
stockholders of record, excluding stockholders whose shares were held in nominee
name.  The  quarterly  high and low sales  prices as reported on the AMEX during
fiscal years 1997 and 1996 are presented below.

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,  Versar's guarantee was reduced from $12.4 million to $1.5 million and the
divestiture was considered complete for accounting purposes.  Fiscal year 1997's
data includes the financial position of Science Management  Corporation (SMC) in
which a majority  interest was  acquired by Versar on May 2, 1997.  As a result,
the SMC revenue and income for the two months  ended June 30, 1997 are  included
in Versar's income statement.  See Notes B, C and F of the Notes to Consolidated
Financial Statements for further information.

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;
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  gross  revenues  for fiscal year 1997  totalled  $48,517,000,  or
$4,234,000  (10%) above  fiscal year 1996 gross  revenue of  $44,283,000.  Gross
revenue for fiscal year 1996 was  $5,193,000  (13%) above that reported in 1995.
The increase in Versar's  revenue in the last fiscal year was  primarily  due to
the acquisition of a majority interest in Science Management Corporation ("SMC")
on May 2, 1997.  Gross revenues of $3,854,000 of SMC are included in fiscal year
1997 from the date of  acquisition  of SMC.  The  increase in gross  revenues in
fiscal year 1996 was due to task orders being  performed in the Company's  Rocky
Mountain   and  Midwest   regions  in  support  of  the  Air  Force  Center  for
Environmental  Excellence  contract.  As  reflected  in the  table  on page  15,
government revenue represented 59% of the total revenue in 1997, compared to 66%
in 1996 and 64% in 1995.  The reduction is  attributable  to the addition of SMC
revenues, which are predominately commercial.

     Purchased services and materials for fiscal year 1997 totalled  $14,947,000
or $2,583,000 (21%) higher than fiscal year 1996 purchased  services.  Purchased
services  for fiscal year 1996 were  $2,621,000  (27%)  higher than  reported in
fiscal year 1995.  The increase in fiscal years 1996 and 1997 was  primarily due
to the increase in gross revenue as mentioned above.

     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  decreased to 80.5% in
1997 compared to 81.4% in 1996 and 81.0% in 1995.  The decreases in fiscal years
1997 and 1996 are  attributable to improved labor  utilization and reduced fixed
operating costs.

     Selling,  general and  administrative  expenses  approximated  15.1% of net
service  revenue  in 1997,  compared  to 15.5%  in 1996 and  17.0% in 1995.  The
decrease is primarily  due to the higher  volume of net service  revenue,  while
selling, general and administrative expenses increased by only 3% in fiscal year
1997.

     Other  income  includes  the  costs  and  revenues  that  are not  directly
attributable to contracts.  In 1997, the Company recognized the remainder of the
non-compete  income from the sale of its  majority-owned  subsidiary  Gammaflux,
Inc. of $42,000  compared to $28,000 in fiscal year 1996,  and $47,000 in fiscal
year 1995. In 1995,

                                       14

<PAGE>

the  remaining  $214,000 of other  income was due to the reversal of $174,000 of
anticipated  costs that were  ultimately not incurred as a result of winning new
contracts and the reduction of other operating reserves of $40,000.

     Losses on Sarnia  Corporation  ("Sarnia")  in fiscal  year 1996 of $142,000
were  recorded in the first six months of fiscal year 1996 compared to losses of
$270,000  in  fiscal  year  1995.  See  Note  C in  the  consolidated  financial
statements.  The Sarnia  losses were recorded as a separate line item due to the
spin-off of Versar's real estate entity to shareholders on June 30, 1994,  which
was completed as of January 25, 1996 for accounting purposes.

     Operating  income for 1997 was  $1,503,000,  an increase  of $631,000  over
fiscal year 1996. The increase is primarily due to a combination of lower direct
costs  of  services  and  selling,  general  and  administrative  expenses  as a
percentage of net service revenue as discussed above. Fiscal year 1996 operating
income   increased   by  $312,000  due  to   decreased   selling,   general  and
administrative expenses as a percentage of net service revenue.

     Interest expense in 1997 was $97,000,  an increase of $1,000 from 1996. The
increase is due to interest cost of $46,000  incurred  during the fourth quarter
associated with financing the acquisition of SMC.  Interest  expense in 1996 was
$96,000,  a decrease of $62,000  from 1995.  The  decrease is due to the reduced
debt in fiscal year 1996.

     Versar's income tax expense for fiscal year 1997 was $150,000 compared to a
tax benefit of $216,000 and $56,000 in fiscal years 1996 and 1995, respectively.
The Company reduced the valuation against the deferred tax assets in each of the
fiscal years due to the assessment of future earnings potential. Refer to Note H
of the Notes to Financial Statements.

     In  summary,  Versar's  net  income  was  $1,256,000  in fiscal  year 1997,
compared  to net  income  of  $992,000  in fiscal  year  1996 and net  income of
$458,000 in fiscal year 1995.

REVENUE

     Versar provides professional services to various industries, government and
commercial  clients.  A summary of revenue  generated from the Company's  client
base is as follows:

     Liquidity and Capital Resources

     The  Company's  operating  activities  provided  $2,184,000 of cash in 1997
primarily from operations.  Non-cash expenses included $722,000 for depreciation
and amortization and stock issued to the ESSOP of $446,000.

                                       15

<PAGE>

     The Company utilized short-term bank financing to supplement its ability to
meet day-to-day  operating cash requirements.  At June 30, 1997, the Company had
$9,141,000 of working capital,  compared to $7,629,000 in 1996.  Working capital
increased by 20% primarily due to the earnings in fiscal year 1997.

     The Company's  accounts  receivable  balance increased by $5,149,000 due to
the acquisition of SMC.

     In  April  1997,  the  Company  moved  its  line  of  credit   facility  to
NationsBank,  N.A. The new line of credit is restricted to the borrowing base of
qualifying  receivables  less the $1,500,000  reserve for a guarantee of debt of
Sarnia and outstanding  acquisition loan balances  (approximately  $1,958,000 at
June 30, 1997).  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 (8.22% at
June 30,  1997).  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, 1997 was
$2,688,000.  Advances on the line are due on November 30, 1998.  The Company was
in compliance with the financial covenants at June 30, 1997. Management believes
that cash  generated by operations and  borrowings  available  under the line of
credit will be adequate to meet the working capital needs for fiscal year 1998.

     As  previously  reported,  Versar has  guaranteed  a five year term loan of
$1,500,000 for Sarnia.  Versar has  established a reserve of $1,500,000  against
the loan.  As the term loan is repaid,  the reserve will be reduced and added to
Versar's equity. In fiscal year 1998, principal payments of $300,000 are due and
will be added back to Versar's equity as they are paid.

Acquisition of Science Management Corporation

     On May 2, 1997,  Versar acquired 53.5% of the outstanding  common stock and
all outstanding preferred stock of SMC for aggregate consideration of $2,870,000
paid 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,  1997) from  NationsBank,
N.A. The remaining  portion of $870,000 was paid with current  working  capital.
Principal payments on the term note of $520,833,  $750,000, and $687,500 are due
in fiscal years 1998, 1999 and 2000, respectively.  On July 29, 1997, Versar and
SMC entered into an Agreement  and Plan of Merger  pursuant to which Versar will
obtain the  remaining  SMC common stock for newly issued shares of Versar common
stock via a merger of SMC with a newly formed wholly owned subsidiary of Versar.
The merger is expected to occur in the second  quarter of fiscal year 1998.  The
transactions  costs associated with the merger are projected to be approximately
$400,000.

New Accounting Standards

     In March 1995, the Financial  Accounting Standard Board issued Statement of
Financial  Accounting  Standards  No. 121,  "Accounting  for the  Impairment  of
Long-Lived  Assets and for  Long-Lived  Assets to be Disposed Of" ("SFAS  121").
SFAS 121 is effective for fiscal year 1997, and requires that long-lived  assets
be reviewed for impairment whenever events or changes in circumstances  indicate
that the  carrying  amount of an asset may not be  recoverable.  The adoption of
SFAS  121 had no  material  effect  on the  financial  position  or  results  of
operations of the Company.

     SFAS 123, "Accounting for Stock-Based  Compensation" was issued in October,
1995 and is effective for fiscal year 1997. The Statement  encourages,  but does
not require,  adoption of the fair value based method of accounting for employee
stock  options  and other  stock  compensation  plans.  The Company has opted to
account  for its stock  option  plan in  accordance  with APB  Opinion  No.  25,
"Accounting  for Stock  Issued to  Employees."  The Company has made certain pro
forma  disclosures of net income and per share  information as if the fair value
based method for accounting defined in SFAS 123 had been applied.

                                       16

<PAGE>

     The Financial  Accounting  Standards  Board issued SFAS 128,  "Earnings per
Share" in  February  1997.  SFAS 128  requires a company  to  present  basic and
diluted earnings per share amounts on the face of the Consolidated Statements of
Operations.  The  Company is required to adopt the  provisions  of the  standard
during the second quarter of 1998, and when adopted, will require restatement of
prior years' earnings per share. The standard will not have a material impact on
historical earnings per share reported by the Company.

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.

                    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, 1997 and 1996, 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,  1997.
These financial  statements are the responsibility of the Company's  management.
Our responsibility is to express an opinion on these financial  statements based
on our audits.

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, 1997 and 1996, and the results of their  operations
and their  cash flows for each of the three  years in the period  ended June 30,
1997, 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.

     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.

     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.

     Intangible  assets:  On April 29, 1996,  Versar purchased for 30,000 common
shares  the  assets of Valu Add,  which was  primarily  contract  vehicles.  The
purchase  resulted in the Company recording  goodwill of $97,500,  which will be
amortized over a five year period.  On May 2, 1997, Versar acquired 53.5% of the
outstanding  common  stock  and  all  outstanding  preferred  stock  of  Science
Management  Corporation  ("SMC"). The Company recorded goodwill of $2,452,000 to
be amortized over fifteen years. Versar believes the customer  relationships and
the  value of  SMC's  business  reputation  were and  continue  to be  long-term
intangible  assets with an almost infinite life. Versar has selected a period of
15 years for  amortization  of the goodwill,  which is  reasonable  based on the
mature businesses of SMC and the compatibility of these businesses with Versar's
business.  Amortization  expense  was  $46,000  and  $19,000  for 1997 and 1996,
respectively. Refer to Note B for further information.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

     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 income per share:  Per share  amounts are  computed by dividing the net
income by the fully diluted weighted average number of common shares outstanding
during the applicable period being reported upon.

     Income  taxes:  The  Company  follows  Statement  of  Financial  Accounting
Standards  No. 109,  "Accounting  for Income  Taxes"  (SFAS 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 $990,000 and $965,000 at June 30, 1997
and 1996, respectively. Versar purchased key-man life insurance policies to fund
the amounts due under the deferred compensation agreements.  The Company borrows
against  the cash  surrender  value of the  policies to pay  premiums.  The cash
surrender value of the policies, net of loans, was $215,000 and $236,000 at June
30, 1997 and 1996, respectively.

     Statements  of cash  flows:  For  statements  of cash flows  purposes,  all
investments with an original  maturity of three months or less are considered to
be cash equivalents.

     Impact of  accounting  standards:  SFAS 123,  "Accounting  for  Stock-Based
Compensation" was issued in October, 1995 and is effective for fiscal year 1997.
The Statement encourages, but does not require, adoption of the fair value based
method of accounting  for employee  stock  options and other stock  compensation
plans.  The Company has opted to account for its stock option plan in accordance
with APB Opinion No. 25, "Accounting for Stock Issued to Employees." The Company
has made certain pro forma  disclosures of net income and per share  information
as if the fair value based  method for  accounting  defined in SFAS 123 had been
applied.

     The Financial  Accounting  Standards  Board issued SFAS 128,  "Earnings per
Share" in  February  1997.  SFAS 128  requires a company  to  present  basic and
diluted earnings per share amounts on the face of the Consolidated Statements of
Operations.  The  Company is required to adopt the  provisions  of the  standard
during the second quarter of 1998, and when adopted, will require restatement of
prior years' earnings per share. The standard will not have a material impact on
historical earnings per share reported by the Company.

NOTE B  ACQUISITION

     On May 2, 1997,  Versar acquired 53.5% of the outstanding  common stock and
all outstanding preferred stock of SMC for aggregate consideration of $2,870,000
paid 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,  1997) from  NationsBank,
N.A. The remaining  portion of $870,000 was paid with current  working  capital.
Principal payments of $520,833,  $750,000, and $687,500 on the term loan are due
in fiscal years 1998, 1999 and 2000,  respectively.  Versar and SMC have entered
into an  Agreement  and Plan of Merger  pursuant to which Versar will obtain the
remaining  SMC  common  stock for newly  issued  shares of Versar  common  stock
subject to the approval of SMC's shareholders. The transactions costs associated
with the merger are projected to be approximately $400,000.

     This  transaction  has been  accounted  for  under the  purchase  method of
accounting.  Operating  results  of SMC have  been  included  with  those of the
Company since the closing date of May 2, 1997.

NOTE C  ASSET DISPOSITIONS

     Gammaflux,    Inc.:   Gammaflux,   Inc.   (Gammaflux),   a   majority-owned
manufacturing subsidiary of the Company, sold substantially all of its assets to
CHC Acquisition Partners,  L.P., an Illinois limited partnership (CHC), pursuant
to an Asset  Purchase  Agreement,  dated June 5, 1991  (effective  May 1, 1991),
among Gammaflux,  the Company,  CHC, the minority shareholder of Gammaflux,  the
general partner of CHC, and the principals of CHC. As a part of the transaction,
CHC agreed to assume certain liabilities of Gammaflux.

     On May 1, 1992,  Versar agreed to the early payout for the note  receivable
and the non-competition agreements. The net cash generated from the early payout
was  approximately  $1,727,000  and was  used to  reduce  debt.  Versar  and the
previous  minority  shareholder  are still bound by the terms of the non-compete
agreement,  and  therefore,  the  Company  has  deferred  certain  income  to be
recognized over the life of the agreement.

     Sarnia  Corporation:  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  guaranty  of Sarnia's  $12.4
million 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.  Versar has
taken a reserve of $1,500,000 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.

June 30, 1997 unbilled receivables will be substantially billed and collected in
fiscal year 1998. Of the $17,525,000 accounts  receivable,  $5,280,000 represent

     Until  April  1997,  Versar  maintained  a bank line of credit for  working
capital  purposes with Riggs National Bank.  Prior to January 25, 1996, the line
provided for advances up to $1,500,000.  On January 25, 1996,  Versar obtained a
new line of credit with Riggs  National  Bank which  provides for advances up to
$3,000,000. Borrowings on the line were at the prime rate of interest plus 1/2%.
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 $3,000,000 based on qualifying  receivables less the $1,500,000  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  (8.22% at June 30,
1997).  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, 1997 was $2,688,000.  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  was in
compliance with the financial  covenants at June 30, 1997.  Management  believes
that cash generated by operations and borrowings available from the bank line of
credit will be adequate to meet the working capital needs for fiscal year 1998.

     Versar obtained a $2,000,000  promissory note from NationsBank on April 30,
1997 for the  acquisition of Science  Management  Corporation  (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, 1997). Principal payment commenced on May 31, 1997 and
is scheduled to be paid in full on April 30, 2000.

     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 July 1, 1997. Versar has
established  a reserve  of  $1,500,000  against  the  loan.  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,  1997,  1996,  and  1995,  approximated
$306,000,  $673,000,  and  $544,000,  respectively,  and  the  weighted  average
interest rates for such periods were 8.78%,  10.82%,  and 10.79%,  respectively.
The  maximum  amount  outstanding  approximated  $1,146,000,   $1,500,000,   and
$1,375,000  during fiscal years 1997,  1996,  and 1995,  respectively.  Weighted
average  interest  rates are computed by relating  the  interest  expense to the
average month-end balance.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

     Interest payments were $62,000,  $89,000, and $157,000 for the fiscal years
ended June 30, 1997, 1996, and 1995, respectively.

NOTE G  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  encourages  superior
performance  for the  Company's  benefit.  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, 1997,  options to purchase an  aggregate  of 924,280  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 $3.940 and
options to purchase an aggregate of 368,835  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:

     At June 30, 1997, 1996, and 1995, options of 560,731,  807,408, and 667,515
shares were exercisable under the 1982, 1992 and 1996 Plans.

     On April 30, 1987,  the Board of Directors  adopted a  Non-Qualified  Stock
Option  Plan.   Participants   in  the  Plan  include   employees,   independent
contractors,  and, in certain circumstances,  Directors of the Company.  Options
are granted by the Board of  Directors  at a price not less than 50% of the fair
market  value at the date of grant  and for a period  not to  exceed  10  years.
Generally, options are issued at 100% of the market value at the date of grant.

     Options under the 1987 Non-Qualified Plan are as follows:

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

     The Company  applies APB 25 and related  interpretations  in accounting for
its  plan.  Accordingly,  no  compensation  cost has been  recognized  for stock
options.  Had  compensation  cost for stock options been determined based on the
fair value at the grant  dates for awards  under this plan  consistent  with the
method of SFAS 123, the Company's net income and net income per share would have
been reduced to the pro forma amounts indicated as follows:

                                                    1997         1996

     In  accordance  with SFAS 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 $1.56 and $1.35
during 1997 and 1996,  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 1997 and 1996:  expected  volatility of
40.5% for both years;  risk-free interest rate of 6%; and expected lives of five
years after the grant date.

NOTE H  INCOME TAXES

     At June 30, 1997, the Company had $74,000 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.

     Income  taxes paid for the years ended June 30, 1997,  1996,  and 1995 were
$307,000, $7,000, and $140,000, respectively.

     Science  Management  Corporation  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 which limits the recoverable  amount to approximately  $4,500,000.  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.  In conjunction with
the proposed Agreement and Plan of Merger (see Note B), the Company is analyzing
its alternatives  with respect to treatment of the acquisition for tax purposes.
Versar will file  consolidated  tax returns  including SMC after it acquires the
remaining 46.5% of SMC common stock. Due to the annual limitations and questions
surrounding the Company's  ability to utilize these  carryforwards,  the Company
has not recorded any benefit or valuation allowances,  effectively reserving the
full amount of the net operating loss  carryforwards.  The Company will finalize
the tax  treatment  in fiscal  year 1998,  as the second  phase of the merger is
finalized.

NOTE I   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 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 1997, 1996, and
1995, 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.

matching contributions approximated $492,000, $473,000, and $434,000, for fiscal
years 1997, 1996, and 1995, 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.  There  were no
contributions  in fiscal years 1997 and 1996,  but $29,000 for fiscal year 1995.
Vesting occurs over time, such that an employee is 100% vested after seven years
of participation.

NOTE J  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  227,000  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
$2,658,000, $2,467,000, and $2,938,000 for 1997, 1996, and 1995, 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.

     FOR VALUE RECEIVED, VERSAR, INC., a corporation organized under the laws of
the State of Delaware and GEOMET  TECHNOLOGIES,  INC., a  corporation  organized
under the laws of the State of Delaware (collectively,  the "Borrowers" and each
a "Borrower"), jointly and severally promise to pay to the order of NATIONSBANK,
N.A., a national banking association, its successors and assigns (the "Lender"),
the  principal  sum of TWO  MILLION  AND  NO/100  DOLLARS  ($2,000,000.00)  (the
"Principal  Sum"),   together  with  interest  thereon  at  the  rate  or  rates
hereinafter provided, in accordance with the following:

1.   Interest.  Commencing as of the date hereof and continuing  until repayment
in full of all sums due hereunder,  the unpaid Principal Sum shall bear interest
at the fluctuating  per annum interest rate  established by the Lender from time
to time,  at its  discretion,  whether or not such rate is  otherwise  published
("Prime Rate"), plus one half of one percent (.50%) per annum. The Prime Rate is
established  by the Lender as an index or base and may or may not be the best or
lowest  rate  charged by the Lender on any loan.  The rate of  interest  charged
under this Note shall change immediately and  contemporaneously  with any change
in the Prime Rate.  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.

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

                                        1

<PAGE>

     (a) Interest on the unpaid  Principal Sum shall be due and payable monthly,
commencing  May 31,  1997,  and on the  last  day of each  month  thereafter  to
maturity; and

     (b)  The  unpaid  Principal  Sum  shall  be  due  and  payable  in  monthly
installments of principal in the amount of $41,666.67  each,  commencing May, 31
1997, and on the last day of each month to and including April 30, 1998; and

     (c) Commencing on May 31, 1998 and continuing on the last day of each month
thereafter until maturity,  the unpaid Principal Sum shall be due and payable in
monthly installments of principal in the amount of $62,500 each; and

     (d) Unless sooner paid, the entire unpaid Principal Sum,  together with all
interest accrued and unpaid thereon,  shall be due and payable in full on April,
30, 2000.

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  (2.0%) 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,  with  application  first  made  to all  principal  installments  then  due
hereunder,  next to the outstanding  principal balance due and owing at maturity
and thereafter to the principal

                                        2

<PAGE>

payments due in the inverse order of maturities.  Notwithstanding  any provision
contained herein to the contrary,  any portion of a permitted partial prepayment
applied to the unpaid  Principal Sum shall be applied  first to the  outstanding
principal  balance due and owing at maturity  and  thereafter  to the  principal
payments due in the inverse order of maturities. 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
__________ 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
upon ten (10)  days  prior  written  notice to the  Lender  without  premium  or
penalty.

7.   Financing Agreement and Other Financing Documents.  This Note is one of the
"Acquisition  Notes" described in a Financing and Security Agreement dated March
31,  1997 by and among the  Borrowers  and the  Lender  (as  amended,  modified,
restated,  substituted,  extended and renewed at any time and from time to time,
the "Financing Agreement").  The indebtedness evidenced by this Note is included
within  the  meaning  of the term  "Obligations"  as  defined  in the  Financing
Agreement.  The term  "Financing  Documents"  as used in this  Note  shall  mean
collectively  this  Note,  the  Financing  Agreement  and any other  instrument,
agreement,  or document  previously,  simultaneously,  or hereafter executed and
delivered by the Borrowers  and/or any other person,  singularly or jointly with
any other person, evidencing, securing, guaranteeing, or in connection with

                                        3

<PAGE>

the Principal Sum, this Note and/or the Financing Agreement.

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 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

                                        4

<PAGE>

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  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

                                        5

<PAGE>

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  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

                                        6

<PAGE>

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 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. The Borrowers acknowledge and agree 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.

                            REVOLVING PROMISSORY NOTE

$3,000,000                                                      McLean, Virginia
                                                                  March 27, 1997

     FOR VALUE RECEIVED, VERSAR, INC., a corporation organized under the laws of
the State of Delaware and GEOMET  TECHNOLOGIES,  INC., a  corporation  organized
under the laws of the State of Delaware (collectively,  the "Borrowers" and each
a "Borrower"), jointly and severally promise to pay to the order of NATIONSBANK,
N.A., a national banking association, its successors and assigns (the "Lender"),
the principal sum of THREE MILLION DOLLARS  ($3,000,000)  (the "Principal Sum"),
or so much  thereof as has been or may be advanced or  readvanced  to or for the
account of the Borrowers  pursuant to the terms and  conditions of the Financing
Agreement (as hereinafter  defined),  together with interest thereon at the rate
or rates hereinafter provided, in accordance with the following:

     1. Interest.

          (a) Except as otherwise expressly set forth below, amounts outstanding
     hereunder shall bear interest at the LIBOR Rate (as  hereinafter  defined),
     plus two hundred and fifty basis points (i.e.  2.50%). For purposes hereof,
     the "LIBOR  Rate" shall mean a  fluctuating  rate equal to 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

                                       1

<PAGE>

     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 President and Chief
     Executive  Officer,  the Vice President,  Treasure & Chief Financial Office
     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

     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  July 1,  1997,  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 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

                                        3

<PAGE>

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  _____________ 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
"Revolving  Promissory Note" described in a Financing and Security  Agreement of
even date  herewith  by and among the  Borrowers  and the  Lender  (as  amended,
modified, restated, substituted,  extended and renewed at any time and from time
to time, the "Financing Agreement").  The indebtedness evidenced by this Note is
included  within  the  meaning  of the  term  "Obligations"  as  defined  in the
Financing Agreement.  The term "Financing  Documents" as used in this Note, each
Acquisition Note, shall mean collectively this Note, the Financing Agreement and
any other instrument,  agreement,  or document  previously,  simultaneously,  or
hereafter  executed and  delivered  by the  Borrowers  and/or any other  person,
singularly or jointly with any other person, evidencing, securing, guaranteeing,
or in  connection  with the  Principal  Sum,  this  Note  and/or  the  Financing
Agreement.

     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:

                                        4

<PAGE>

          (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; 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  Borrower 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 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

                                        5

<PAGE>

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  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

                                        6

<PAGE>

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

                                        7

<PAGE>

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 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 BE PARTIES,
ARISING OUT OF OR IN ANY WAY  PERTAINING  TO (A) THIS NOTE OR (B) THE  FINANCING

II.  BORROWING

     SECTION 2.1 (a) The  Acquisition  Loans.  Subject to and in accordance with
the provisions of this  Agreement,  the Lender agrees from time to time from the
Closing Date until  November 30, 1998, to lend (each an  "Acquisition  Loan" and
collectively  the  "Acquisition  Loans")  to  the  Borrowers  such  sums  as the
Borrowers request and as the Lender approves  pursuant to this Agreement,  up to
the maximum aggregate principal amount of Five Million Dollars ($5,000,000) (the
"Acquisition Loan Committed Amount").

     (b) Proceeds of the Acquisition  Loans.  The proceeds of each advance under
the  Acquisition  Loan  shall  be used  by the  Borrowers  to  make a  Permitted
Acquisition in accordance with Section 8.04 of this Agreement,  and for no other
purposes except as may otherwise be agreed by the Lender in writing.

     (c) Procedure for Making  Acquisition Loans. The Borrowers may borrow under
the  Acquisition  Loan on any Banking Day. The Borrowers shall notify the Lender
no  later  than  ten  (10)  Banking  Days  prior  to the date of the date of the
proposed  borrowing.  The Lender will not lend more than  seventy  five  percent
(75%) of the Purchase  Price of any  Acquisition.  The Lender shall not consider
making an advance  under the  Acquisition  Loan  unless  the  Lender  shall have
received and approved  with respect to such advance,  among other things;  (i) a
pro forma post acquisition  balance statement,  income statement,  and cash flow
statement,  (ii) a  listing  of all  assets  to be  acquired,  (iii)  historical
financial statements on the Target (as hereinafter  defined);  (iv) the proposed
terms  and  conditions  for  the  proposed  acquisition;   and  (v)  such  other
information as the Lender may request.

     (d)  Acquisition  Loan  Notes.  The joint  and  several  obligation  of the
Borrowers to repay with  interest each advance made under the  Acquisition  Loan
made by the Lender from time to time shall be evidenced by an  Acquisition  Note
(as from time to time extended,  amended,  restated,  supplemented  or otherwise
modified, each an "Acquisition Note" and collectively,  the "Acquisition Notes")
substantially  in the form set forth in EXHIBIT "A-1" attached hereto and made a
part hereof, with appropriate insertions, dated as of the date of each advance.

     SECTION  2.2 The  Revolving  Loan.  (a) The  Lender  agrees  to lend to the
Borrowers  and the Borrowers  agree to borrow on a revolving  basis from time to
time the  principal  amount  (the  "Revolving  Loan")  not to exceed at any time
outstanding the lesser (the "Revolving Loan Committed  Amount") of Three Million
Dollars ($3,000,000) or the Borrowing Base.

                                       11

<PAGE>

     (b) If at any time the outstanding  principal balance of the Revolving Loan
exceeds the limitations  provided in subsection (a) above, the Borrowers promise
to pay to the order of the Lender, on demand, the amount of the excess.

     (c) The joint and several obligation of the Borrowers to repay the advances
under  the  Revolving  Loan  shall  be  evidenced  by the  Borrowers'  Revolving
Promissory Note of even date herewith (the "Revolving  Promissory Note") payable
to the  Lender in the form  attached  hereto as  EXHIBIT  "A-2".  The  Revolving
Promissory  Note shall bear interest and shall be repaid by the Borrowers in the
manner and at the times set forth in the Revolving Promissory Note.

     (d) The Borrowers may prepay the principal sum outstanding on the Revolving
Loan only in accordance  with the terms of the Revolving Note. Sums borrowed and
repaid may be readvanced under the terms and conditions of this Agreement.

     (e) The proceeds of the  Revolving  Loan shall be used by the Borrowers for
the purposes set forth in Recital A above,  and, unless prior written consent of
the Lender is obtained, for no other purpose.

     SECTION 2.3 Revolving Loan Procedure.  (a) Each advance under the Revolving
Loan shall be in an amount of not less than $10,000, or a multiple thereof.  The
Borrowers  shall  notify the  Lender not late than 1:00 p.m.  on the date of any
proposed advance.

     (b) The Borrowers shall furnish to the Lender such schedules, certificates,
lists,  records,  reports,  information  and documents as required by the Lender
from time to time so that the  Lender  may,  in its  discretion,  determine  the
Borrowing Base.

     (c) In addition,  the Borrowers hereby irrevocably  authorize the Lender to
make  advances  under  the  Revolving  Loan at any time  and from  time to time,
without  further request from or notice to the Borrowers,  which the Lender,  in
its sole and absolute discretion,  deems necessary or appropriate to protect the
Lender's  interests  under  this  Agreement  or  otherwise,  including,  without
limitation, advances made to cover Overdrafts, principal of, and/or interest on,
any  Loans,  fees,  and/or  Enforcement  Costs,  prior  to,  on,  or  after  the
termination of this Agreement, regardless of whether the aggregate amount of the
advances  which the Lender  may make  hereunder  exceeds  the  Revolving  Credit
Committed  Amount.  The Lender shall have no  obligation  whatsoever to make any
advance under this  subsection and the making of one or more advances under this
subsection  shall not  obligate  the  Lender to make  other  similar  advance or
advances. Any such advances will be secured by the Collateral.

     (d) The Lender is authorized to deduct any payment  (including  payments of
principal,  interest  and/or Fees as  provided  herein or in the Notes) from the
Borrowers' Account Number _____________ 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

                                       12

<PAGE>

due and,  further  provided,  that the Lender will  provide the  Borrowers  with
notice of any such deduction.

     SECTION 2.4 Revolving Loan Account.  The Lender will establish and maintain
a loan account on its books (the  "Revolving  Loan Account") to which the Lender
will ( debit (i) the principal  amount of each Revolving Loan made by the Lender
hereunder as of the date made,  (ii) the amount of any  interest  accrued on the
Revolving  Loans as and when due, and (ii) any other  amounts due and payable by
the  Borrowers  to the  Lender  from time to time under the  provisions  of this
Agreement in connection with the Revolving Loans, including, without limitation,
Enforcement Costs, Fees, late charges,  and service,  collection and audit fees,
as and when due and payable,  and (b) credit all payments  made by the Borrowers
to the Lender on account of the Revolving  Loans as of the date made  including,
without  limitation,  funds credited to the Collateral Account and collected and
paid to the Lender,  the Lender  reserving the right,  exercised in its sole and
absolute  discretion from time to time, to provide earlier credit or to disallow
credit for any Collection which is unsatisfactory to the Lender.

     The  Lender  may debit the  Revolving  Loan  Account  for the amount of any
Collection  which is returned to the Lender  unpaid.  All credit  entries to the
Revolving  Loan Account are  conditional  and shall be readjusted as of the date
made if final and indefeasible  payment is not received by the Lender in cash or
solvent credits. The Borrowers hereby promise to pay to the order of the Lender,
on demand,  an amount equal to the excess, if any, of all debit entries over all
credit  entries  recorded in the Revolving  Loan Account under the provisions of
this Agreement.

     SECTION 2.5 Collateral  Account.  The Borrowers will deposit or cause to be
deposited to a bank account  designated  by the Lender and from which the Lender
alone has power of access and withdrawal (the "Collateral  Account"),  all Items
of  Payment.  The  Borrowers  shall  deposit  Items of Payment for credit to the
Collateral  Account  not later  than the next  Banking  Day  after  the  receipt
thereof, and in precisely the form received,  except for the endorsements of the
Borrowers where necessary to permit the collection of any such Items of Payment,
which  endorsement the Borrowers  hereby agree to make.  Pending such deposit to
the Collateral Account, endorsement and/or other delivery thereof to the Lender,
the  Borrowers  will not  commingle  any Items of Payment  with any of its other
funds or property,  but will hold them separate and apart therefrom in trust and
for the account of the Lender.  The Lender is not,  however,  required to credit
the Collateral  Account for the amount of any Collection which is unsatisfactory
to the Lender.  In addition,  the Borrowers shall, if so directed by the Lender,
establish a lock box to which Items of Payments may be sent and shall direct the
Borrowers' customers and others as the Lender may require to forward payments to
that lock box.  Items of Payment  received in the lock box shall be deposited in
the Collateral Account or as otherwise directed by the Lender from time to time.

     SECTION 2.6 Commitment Fee. The Borrowers agree to pay to the Lender on the
first day of each calendar quarter commencing after the date of this Agreement a
commitment fee (computed on the basis of a year  consisting of three hundred and
sixty (360) days for the actual

                                       13

<PAGE>

number of days  elapsed) of one  quarter of one percent  (.25%) per annum on the
daily average of the unused amount of the Revolving Loan.

     SECTION 2.7 Acquisition  Loan Fee. The Borrowers agree to pay to the Lender
a fee  in  conjunction  with  each  advance  under  the  Acquisition  Loan.  The
Acquisition  Loan fee will be one half of one  percent  (.50%)  per annum of the
amount of each Acquisition Note and shall be payable on the date of each advance
under the  Acquisition  Loan.  THE  BORROWERS  ACKNOWLEDGE  AND  AGREE  THAT THE
ACQUISITION LOAN FEE IS PAID IN CONSIDERATION OF THE LENDER'S  PROCESSING OF THE
BORROWERS' CREDIT  APPLICATION,  AND IS NOT INTENDED AS A COMMITMENT FEE FOR THE
ACQUISITION  LOAN FACILITY;  PAYMENT OF THE ACQUISITION  LOAN FEE SHALL UNDER NO
CIRCUMSTANCES  OBLIGATE  THE LENDER TO MAKE ANY FUTURE  ADVANCES  OR APPROVE ANY
DISCRETIONARY ACQUISITIONS UNDER THE ACQUISITION LOAN FACILITY.

     SECTION 2.8 Transactions under this Agreement Between the Borrowers and the
Lender.  In respect to any advance and all other  matters under or in connection
with this  Agreement 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 any employee or
representative  of the Company  designated by the Borrowers in writing delivered
to the  Lender  from  time to time.  The  Borrowers  each  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,  releases and
discharges  the Lender from any and all  responsibility  or  liability  for, and
agrees 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.

     SECTION 2.9 Account Statements. Any and all periodic or other statements or
reconciliations,   and  the  information   contained  in  those   statements  or
reconciliations, of the Revolving Loan Account shall be presumed conclusively to
be correct and shall  constitute  an account  stated  between the Lender and the
Borrowers unless the Lender receives specific written objection thereto from the
Borrowers within thirty (30) Banking Days after such statement or reconciliation
shall have been sent by the Lender.

     SECTION  2.10  Overdraft  Advances.  If, after the close of business on any
Banking  Day,  any  banking  account  of  either  Borrower  with the  Lender  is
determined  by the  Lender  to  have  an  Overdraft,  the  Lender,  in its  sole
discretion  on each  and any  such  occasion  may  (and  is  hereby  irrevocably
authorized by the Borrowers  to), but is not obligated to, make an advance under
the

                                       14

<PAGE>

Revolving  Loan  to the  Borrowers  in a  principal  amount  equal  to any  such
Overdraft as of the close of business on such Banking Day. All Overdrafts  shall
be secured by the Collateral.

III. COLLATERAL

     As security for the payment of all of the Obligations, each Borrower hereby
assigns,  grants and conveys to the Lender and agrees that the Lender shall have
a  perfected,  continuing  security  interest  in all of  the  Collateral.  Each
Borrower further agrees that the Lender shall have in respect the Collateral all
of the  rights  and  remedies  of a secured  party  under the  Virginia  Uniform
Commercial Code and under other applicable Laws and Security Documents,  as well
as those  provided in this  Agreement.  Each  Borrower  covenants  and agrees to
execute and deliver such financing  statements and other instruments and filings
as are necessary in the opinion of the Lender to perfect such security interest.
Notwithstanding  the fact that the proceeds of the Collateral  constitute a part
of the Collateral,  neither Borrower may dispose of the Collateral,  or any part
thereof,  other than in the ordinary  course of its business or as otherwise may
be permitted by this Agreement.

IV.  UNCONDITIONAL OBLIGATIONS

     The payment and  performance by the Borrowers of the  Obligations  shall be
absolute  and  unconditional,  irrespective  of any  defense  or any  rights  of
set-off, recoupment or counterclaim they might otherwise have against the Lender
and the Borrowers shall pay absolutely net all of the  Obligations,  free of any
deductions and without  abatement,  diminution or set-off;  and until payment in
full  of all of  the  Obligations,  the  Borrowers:  (a)  will  not  suspend  or
discontinue any payments provided for in the Notes; (b) will perform and observe
all of their other agreements  contained in this Agreement,  including  (without
limitation)  all  payments  required to be made to the Lender;  and (c) will not
terminate or attempt to terminate this Agreement for any cause.

V.   REPRESENTATIONS AND WARRANTIES

     To induce  the  Lender to make the  Loans,  each  Borrower  represents  and
warrants to the Lender and,  unless the Lender is notified by either Borrower of
a change or changes  effecting such  representations  and  warranties,  shall be
deemed to  represent  and warrant to the Lender at the time each  request for an
advance  under the Loans is submitted  and again at the time any advance is made
under the Loans that:

     SECTION 5.1 Subsidiaries. Geomet is the Company's only Subsidiary.

     SECTION 5.2 Good Standing.  The Company and each of its Subsidiaries (a) is
a corporation  duly  organized,  existing and in good standing under the laws of
the  jurisdiction of its  incorporation,  (b) has the corporate power to own its
property  and to carry on its business as now being  conducted,  and (c) is duly
qualified to do business and is in good standing in each  jurisdiction  in which
the character of the properties  owned by it therein or in which the transaction
of its business makes such qualification necessary.

                                       15

<PAGE>

     SECTION 5.3 Power and Authority.  The Company and each of its  Subsidiaries
has full power and  authority to execute and deliver this  Agreement and each of
the  other  Financing  Documents  executed  and  delivered  by it,  to make  the
borrowing hereunder,  and to incur the Obligations,  all of which have been duly
authorized by all proper and necessary  corporate action. No consent or approval
of  stockholders  or of any public  authority  is required as a condition to the
validity  or  enforceability  of this  Agreement  or any of the other  Financing
Documents executed and delivered by the Borrowers.

     SECTION  5.4  Binding  Agreements.  This  Agreement  and each of the  other
Financing  Documents  executed and delivered by the Borrowers have been properly
executed by each Borrower,  constitute valid and legally binding  obligations of
the  Borrowers,  and are fully  enforceable  against the Borrowers in accordance
with their respective terms.

     SECTION  5.5  Litigation.  There are no  proceedings  pending or, so far as
either  Borrower knows,  threatened  before any court or  administrative  agency
which will materially  adversely affect the financial condition or operations of
the Company or any Subsidiary, or the authority of either Borrower to enter into
this Agreement or any of the other Financing Documents executed and delivered by
the Borrowers.

     SECTION 5.6 No Conflicting  Agreements.  There is (a) no charter, by-law or
preference  stock  provision of either Borrower and no provision of any existing
mortgage,  indenture,  contract  or  agreement  binding  on either  Borrower  or
affecting its property,  and (b) to the knowledge of each Borrower, no provision
of law or order of court binding upon the  Borrowers,  which would conflict with
or in any way prevent the  execution,  delivery,  or performance of the terms of
this Agreement or of any of the other Financing Documents executed and delivered
by the  Borrowers,  or which would be  violated  as a result of such  execution,
delivery or performance.

     SECTION 5.7 Financial  Condition.  The financial  statements of the Company
dated June 30, 1996 are complete and correct and, in the opinion of the Company,
fairly  present the  current  financial  condition  of the Company and have been
prepared in accordance  with GAAP applied on a consistent  basis  throughout the
period involved. There are no material liabilities, direct or indirect, fixed or
contingent, of either Borrower as of the date of such financial statements which
are not  reflected  therein or in the notes  thereto.  There has been no adverse
change in the financial  condition or operations  of either  Borrower  since the
date of such financial  statements  (and to each Borrower's  knowledge,  no such
adverse change is pending or threatened),  and the Borrowers have not guaranteed
the  obligations  of, or made any  investments  in or advances  to, any company,
individual or other entity except as disclosed in such financial statements.

     SECTION 5.8 Taxes. Each Borrower has filed or has caused to have been filed
all  federal,  state  and local  tax  returns  which,  to the  knowledge  of the
Borrowers,  are  required to be filed,  and has paid or caused to have been paid
all taxes as shown on such returns or on any  assessment  received by it, to the
extent that such taxes have become due,  unless and to the extent only that such
taxes,  assessments  and  governmental  charges are currently  contested in good
faith and by appropriate

                                       16

<PAGE>

proceedings  by  the  Borrowers  and  adequate   reserves   therefor  have  been
established as required under generally accepted accounting principles.

     SECTION 5.10 Compliance With Law.  Neither  Borrower is in violation of any
law,  ordinance,  governmental rule or regulation to which it is subject and the
violation  of which would have a material  adverse  effect on the conduct of its
business,  and  each  Borrower  has  obtained  any  and all  licenses,  permits,
franchises or other governmental  authorizations  necessary for the ownership of
its properties and the conduct of its business.

     SECTION 5.11 Place(s) of Business and Location of Collateral. The Borrowers
warrant  that the  address  of each  Borrower's  chief  executive  office  is as
specified  in  EXHIBIT C  attached  hereto  and made a part  hereof and that the
address  of each  other  place  of  business  of the  Borrowers,  if any,  is as
disclosed to the Lender in EXHIBIT C. The  Collateral  and all books and records
pertaining to the Collateral are and will be located at the address indicated on
EXHIBIT C. Each  Borrower will  immediately  advise the Lender in writing of the
opening  of any new place of  business  or the  closing  of any of its  existing
places of  business,  and of any change in the  location of the places where the
Collateral,  or any part  thereof,  or the  books  and  records  concerning  the
Collateral,  or any part thereof,  are kept.  The proper and only places to file
financing  statements  with respect to the Collateral  within the meaning of the
Uniform  Commercial  Code are the Circuit Court for Fairfax County and the State
Corporation Commission.  A copy of a fully executed financing statement shall be
sufficient to satisfy for all purposes the requirements of a financing statement
as set forth in Article 9 of the Virginia Uniform Commercial Code.

     SECTION 5.12 Title to  Properties.  Each  Borrower has good and  marketable
title to all of its properties,  including the Collateral, and the Collateral is
free and clear of  mortgages,  pledges,  liens,  charges and other  encumbrances
other than the Permitted Liens.

     SECTION 5.13 Margin Stock.  None of the proceeds of the Loans will be used,
directly  or  indirectly,  by the Company or any  Subsidiary  for the purpose of
purchasing  or  carrying,  or for  the  purpose  of  reducing  or  retiring  any
indebtedness  which was  originally  incurred to purchase or carry,  any "margin
security"  within the  meaning  of  Regulation  G (12 CFR Part 207),  or "margin
stock"  within the meaning of  Regulation  U (12 CFR Part 221),  of the Board of
Governors of the Federal  Reserve System  (herein  called "margin  security" and
"margin  stock") or for any other  purpose  which  might  make the  transactions
contemplated  herein a "purpose  credit" within the meaning of said Regulation G
or Regulation U, or cause this Agreement to violate any other  regulation of the
Board of Governors of the Federal Reserve System or the Securities  Exchange Act
of 1934 or the Small Business  Investment Act of 1958, as amended,  or any rules
or regulations promulgated under any of such statutes.

     SECTION  5.14  ERISA.  With  respect  to any  "pension  plan" as defined in

contributed to by either Borrower and/or by any Commonly  Controlled Entity: (a)
no  "accumulated  funding  deficiency" as defined in Code ss.412 or ERISA ss.302
has occurred, whether or not that accumulated funding deficiency has

                                       17

<PAGE>

been waived; (b) no "reportable event" as defined in ERISA ss.4043 has occurred;
(c) no  termination  of any plan subject to Title IV of ERISA has occurred;  (d)
neither any Borrower nor any Commonly Controlled Entity has incurred a "complete
withdrawal" within the meaning of ERISA ss.4203 from any multiemployer plan; (e)
neither any Borrower nor any Commonly  Controlled Entity has incurred a "partial
withdrawal"   within  the  meaning  of  ERISA   ss.4205   with  respect  to  any
multiemployer  plan;  (f) no  multiemployer  plan to which any  Borrower  or any
Commonly   Controlled   Entity   has  an   obligation   to   contribute   is  in
"reorganization"  within  the  meaning  of ERISA  ss.4241  nor has  notice  been
received  by  any  Borrower  or  any  Commonly  Controlled  Entity  that  such a
multiemployer plan will be placed in "reorganization".

     SECTION 5.15 Governmental Consent. Neither the nature of any Borrower or of
its business or properties,  nor any  relationship  between any Borrower and any
other entity or person,  nor any  circumstance  in connection with the making of
the Loans,  or the offer,  issue,  sale or  delivery  of the Notes is such as to
require a consent,  approval or  authorization  of, or filing,  registration  or
qualification with, any governmental  authority, on the part of any Borrower, as
a condition to the execution and delivery of this  Agreement or any of the other
Financing Documents,  the borrowing of the principal amounts of the Loans or the
offer, issue, sale or delivery of the Notes.

     SECTION 5.16 Inventory.  With respect to all Inventory of each Borrower, as
reflected on the books and records of each  Borrower,  (a) such  Inventory is of
good and merchantable  quality, free from defects, and (b) such Inventory is not
stored with a bailee,  warehouseman  or similar  party,  and such  Inventory  is
located at the places of business indicated on EXHIBIT C.

     SECTION 5.17 Full Disclosure.  The financial statements referred to in this
Part V do not, nor does this Agreement,  nor do any written statements furnished
by the  Borrowers  to the  Lender in  connection  with the  making of the Loans,
contain  any  untrue  statement  of fact or omit a fact  necessary  to make  the
statements  contained  therein or herein not misleading.  There is no fact which
the  Borrowers  have not  disclosed  to the Lender in writing  which  materially
adversely  affects or, will or could prove to  materially  adversely  affect the
properties,  business,  prospects, profits or condition (financial or otherwise)
of the Borrowers or the ability of either Borrower to perform this Agreement.

     SECTION  5.18  Presence  of  Hazardous  Materials  or  Hazardous  Materials
Contamination.  To the  best  of each  Borrower's  knowledge,  (a) no  Hazardous
Materials are located on any real property  owned,  controlled or operated by of
either  Borrower  or for  which  either  Borrower  is  responsible,  other  than
reasonable  quantities of Hazardous  Materials stored or kept by either Borrower
in the  ordinary  course  of its  current  line  of  business,  which  Hazardous
Materials  are at all  times  stored,  used  and  disposed  in  accordance  with
applicable  Laws;  and (b) no property  owned,  controlled or operated by either
Borrower  has ever  been  used as a  manufacturing,  storage,  or dump  site for
Hazardous Materials nor is affected by Hazardous Materials  Contamination at any

     SECTION 5.19 Intellectual Property.  Each Borrower owns or possesses rights
to use all of the patents,  trademarks,  service marks, trade names,  copyrights
and licenses and all rights with respect  thereto  necessary for the present and
planned  future  operation of its business,  without any known conflict with the
rights of any other Person.

     SECTION 5.20 Business Names and Addresses.  In the five (5) years preceding
the date hereof,  neither  Borrower has conducted  business under any name other
than its current name nor conducted its business in any jurisdiction  other than
those disclosed on EXHIBIT C attached hereto.

     SECTION 5.21  No  Default.  There is no Event of  Default  (as  hereinafter
defined) and no event has occurred and no condition exists which with the giving
of notice or the passage of time would  constitute an Event of Default.  Neither
Borrower is in default  under the terms of any other  agreement or instrument to
which it may be a party or by which the  Collateral or any of its properties may
be bound or subject.

     SECTION 5.22 Compliance with  Eligibility  Standards.  Unless the Lender is
advised by the Borrowers in writing to the contrary,  each Account  described in
any schedule,  certificate, record and data furnished to the Lender for purposes
of  calculating  the  Borrowing  Base will at all times meet and comply with the
Eligibility Standards.

     SECTION 5.23 Accounts. With respect to all Accounts and to the best of each
Borrower's knowledge (a) they are genuine, and in all respects what they purport
to be, and are not  evidenced by a judgment,  an  instrument,  or chattel  paper
(unless such judgment has been assigned and such instrument or chattel paper has
been endorsed and delivered to the Lender); (b) they represent undisputed,  bona
fide  transactions  completed  in  accordance  with  the  terms  and  provisions
contained in the invoices and purchase  orders relating  thereto;  (c) the goods
sold (or services  rendered) which resulted in the creation of the Accounts have
been  delivered  or rendered to and  accepted  by the  account  debtor;  (d) the
amounts shown on each  Borrower's  books and records,  with respect  thereto are

lease of which gave rise to an Account,  the  Borrowers  will (unless the Lender

otherwise  completely  service all of the  Accounts  including  (i) the billing,
posting and maintaining of complete  records  applicable  thereto,  and (ii) the
taking of such action with respect to such Accounts as the Lender may request or
in the absence of such request,  as the Company and each of the Subsidiaries may
deem advisable;  and (b) may grant,  in the ordinary course of business,  to any
account debtor, any rebate, refund or adjustment to which the account debtor may
be lawfully  entitled,  and may accept, in connection  therewith,  the return of
goods,  the sale or lease of which  shall  have given  rise to an  Account.  The
Lender  may,  at its  option,  at any time or from  time to time  after  default
hereunder,  revoke the collection privilege given to the Company and each of the
Subsidiaries  herein by either giving notice of its  assignment  of, and lien on

under  such  contracts  with  potential  values in excess of  $500,000  shall be
assigned  to the Lender and notice  thereof  given to the  government  under the
Federal  Assignment of Claims Act or any other applicable law. In addition,  the
Lender  may,  without  notice  to  the  Borrowers,  discuss  the  status  of any
Government  Contract with the contracting officer responsible for such contract,
and the Borrowers  will  cooperate  with the Lender and its agents in connection
with such discussions.

     SECTION 7.29 Hazardous  Materials;  Contamination.  Each Borrower agrees to
(a) give  notice to the Lender  immediately  upon  either  Borrower's  acquiring
knowledge  of the  presence  of any  Hazardous  Materials  Contamination  on any
property  owned or leased by either  Borrower  or for which  either  Borrower is
responsible,  with a full description  thereof; (b) comply at all times with any
Laws  governing  the handling,  requiring the removal,  treatment or disposal of
Hazardous Materials or Hazardous Materials  Contamination and provide the Lender
with satisfactory evidence of such compliance; (c) in the event of any Hazardous

available to pay the cost of removing, treating, and disposing of such Hazardous
Materials  Contamination  and discharging any Lien which may be established as a
result  thereof on any property  owned or controlled  by either  Borrower or for
which  either  Borrower  is  responsible;  and (d)  defend,  indemnify  and hold
harmless the Lender and its agents, employees,  trustees, successors and assigns
from any and all claims which may now or in the future  (whether before or after
the  termination  of this  Agreement) be asserted as a result of the presence of

for  which  either   Borrower  is  responsible   for  any  Hazardous   Materials
Contamination.

     SECTION 10.3  Performance by Lender.  If either  Borrower shall fail to pay
the Obligations or otherwise fail to perform,  observe or comply with any of the
material conditions,  covenants,  terms, stipulations or agreements contained in
this  Agreement  or any of the other  Financing  Documents,  the Lender  without
notice to or demand upon the Borrowers  and without  waiving or releasing any of

and other  property of any nature  whatsoever  of either  Borrower now or at any
time hereafter in the possession of, in transit to or from, under the control or
custody  of, or on deposit  with,  the Lender.  Upon  demand by the Lender,  the
Borrowers shall assemble the Collateral and make it available to the Lender,  at
a place  designated by the Lender.  The Lender or its agents may enter upon each
Borrower's  premises  to take  possession  of the  Collateral,  to remove it, to
render it unusable, or to sell or otherwise dispose of it.

Lender with respect to the  Collateral  which is sent by regular  mail,  postage
prepaid,  to the  Borrowers at the address set forth in Part XI hereof,  or such
other  address  of the  Borrowers  which  may from  time to time be shown on the

proceeds of sale or other  disposition of the Collateral  will be applied by the
Lender to the payment of the  Liquidation  Costs and Expense  Payments,  and any
balance of such  proceeds  will be  applied by the Lender to the  payment of the
balance of the Obligations in such order and manner of application as the Lender
may from time to time in its sole discretion  determine.  After such application
of the  proceeds,  any balance  shall be paid to the  Borrowers  or to any other
party entitled thereto.

     SECTION  11.2  Consents  and  Approvals.  If  any  consent,   approval,  or
authorization of any state, municipal or other governmental  department,  agency
or authority or of any person, or

                                       36

<PAGE>

any  person,  corporation,  partnership  or other  entity  having  any  interest
therein,  should be necessary to effectuate any sale or other disposition of the
Collateral,  the  Borrowers  agree to execute  all such  applications  and other
instruments, and to take all other action, as may be required in connection with
securing any such consent, approval or authorization.

     SECTION 11.3 Remedies, etc. Cumulative. Each right, power and remedy of the
Lender  as  provided  for in this  Agreement  or in any of the  other  Financing
Documents  or now or  hereafter  existing  at law or in equity or by  statute or
otherwise  shall be cumulative  and concurrent and shall be in addition to every
other right,  power or remedy  provided  for in this  Agreement or in any of the
other Financing  Documents or now or hereafter  existing at law or in equity, by
statute or  otherwise,  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.  In order to entitle  the Lender to  exercise  any
remedy  reserved  to it herein,  it shall not be  necessary  to give any notice,
other than such notice as may be expressly required in this Agreement.

     SECTION 11.4 No Waiver of Rights by the Lender.  No failure or delay by the
Lender to insist upon the strict performance of any term, condition, covenant or
agreement of this Agreement or of 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 any later time or times.  By accepting  payment  after the due date of
any amount  payable  under this  Agreement  or under any of the other  Financing
Documents,  the Lender  shall not be deemed to waive the right either to require
prompt  payment when due of all other amounts  payable  under this  Agreement or
under any of the other Financing Documents,  or to declare a default for failure
to effect such prompt payment of any such other amount.

     SECTION 11.5 Entire Agreement. The Financing Documents shall completely and
fully supersede all other agreements,  both written and oral, between the Lender
and the  Borrowers  relating  to the  Obligations.  Neither  the  Lender nor the
Borrowers shall hereafter have any rights under such prior  agreements but shall
look solely to the Financing  Documents for definition and  determination of all
of their respective  rights,  liabilities and  responsibilities  relating to the
Obligations.

     SECTION 11.6 Survival of Agreement;  Successors and Assigns. All covenants,
agreements,  representations  and warranties made by the Borrowers herein and in
any  certificate,  in the Financing  Documents and in any other  instruments  or
documents  delivered  pursuant  hereto shall survive the making by the Lender of
the Loans and the  execution  and delivery of the Notes,  and shall  continue in
full  force and effect so long as any of the  Obligations  are  outstanding  and
unpaid,  INCLUDING,  BUT NOT LIMITED TO,  REPAYMENT  IN FULL OF ALL  OBLIGATIONS
UNDER THE SARNIA DOCUMENTS. Whenever in this Agreement any of the parties hereto
is referred to, such  reference  shall be deemed to include the  successors  and
assigns of such party;  and all  covenants,  promises  and  agreements  by or on
behalf of the Borrowers,  which are contained in this  Agreement  shall inure to
the benefit of the successors and assigns of the Lender, and all covenants,

                                       37

<PAGE>

promises and  agreements  by or on behalf of the Lender  which are  contained in
this  Agreement  shall  inure to the  benefit of the  permitted  successors  and
permitted  assigns of the  Borrowers,  but this Agreement may not be assigned by
the Borrowers without the prior written consent of the Lender.

     SECTION  11.7  Expenses.  Each  Borrower  agrees  to pay all  out-of-pocket
expenses of the Lender  (including the reasonable fees and expenses of its legal
counsel) in connection with the  preparation of this Agreement,  the recordation
of all financing statements and such other instruments as may be required by the
Lender at the time of, or  subsequent  to, the  execution  of this  Agreement to
secure the  Obligations  (including any and all  recordation tax and other costs
and taxes  incident to  recording),  the  enforcement  of any  provision of this
Agreement  and the  collection  of the  Obligations.  Each  Borrower  agrees  to
indemnify  and save  harmless the Lender for any  liability  resulting  from the
failure to pay any required recordation tax, transfer taxes,  recording costs or
any other expenses  incurred by the Lender in connection  with the  Obligations.
The  provisions of this Section shall survive the execution and delivery of this
Agreement and the repayment of the Obligations.  Each Borrower further agrees to
reimburse  the Lender  upon  demand for all  out-of-pocket  expenses  (including
reasonable  attorneys'  fees and  legal  expenses)  incurred  by the  Lender  in
enforcing any of the Obligations or any security therefor, which agreement shall
survive the termination of this Agreement and the repayment of the Obligations.

     SECTION 11.8 Counterparts.  This Agreement may be executed in any number of
counterparts all of which together shall constitute a single instrument.

     SECTION 11.9 Governing  Law. This Agreement and all of the other  Financing
Documents shall be governed by, and construed in accordance with the laws of the
State.

     SECTION 11.10 Modifications.  No modification or waiver of any provision of
this Agreement or of any of the other  Financing  Documents,  nor consent to any
departure by the Borrowers therefrom, shall in any event be effective unless the
same shall be in  writing,  and then such waiver or consent  shall be  effective
only in the specific  instance and for the purpose for which given. No notice to
or demand on the  Borrowers in any case shall entitle the Borrowers to any other
or further notice or demand in the same, similar or other circumstance.

     SECTION 11.11  Illegality.  If fulfillment  of any provision  hereof or any
transaction  related hereto or to any of the other Financing  Documents,  at the
time performance of such provision shall be due, shall involve  transcending the
limit of validity  prescribed  by law,  then ipso facto,  the  obligation  to be
fulfilled  shall be reduced to the limit of such validity;  and if any clause or
provisions  herein  contained  other than the  provisions  hereof  pertaining to
repayment  of  the  Obligations  operates  or  would  prospectively  operate  to
invalidate  this  Agreement  in whole or in part,  then such clause or provision
only shall be void,  as though not herein  contained,  and the remainder of this
Agreement  shall  remain  operative  and in full force and  effect;  and if such
provision  pertains to repayment of the Obligations,  then, at the option of the
Lender,  all of the  Obligations  of the  Borrowers  to the Lender  shall become
immediately due and payable.

                                       38

<PAGE>

     SECTION 11.12 Extension of Maturity. Should the principal of or interest on
the Notes  become  due and  payable on other than a Banking  Day,  the  maturity
thereof shall be extended to the next succeeding  Banking Day and in the case of
principal,  interest shall be payable thereon at the rate per annum specified in
the Notes during such extension.

include  the  plural,  the plural  the  singular  and the use of the  masculine,
feminine or neuter gender shall include all genders.

     SECTION 11.14 Headings.  The headings in this Agreement are for convenience
only and shall not limit or otherwise affect any of the terms hereof.

     SECTION  11.15  Waiver of Trial by Jury.  The parties  hereto  hereby waive
trial by jury in any action or  proceeding to which both of them may be parties,
arising out of or in any way  pertaining to (a) this  Agreement,  (b) the Loans,
Obligations, and Collateral which are the subject of this Agreement, and (c) any
and all notes, guarantees, assignments or agreements of any kind relating to the
Loans.  It is agreed and  understood  that this waiver  constitutes  a waiver of
trial by jury of all claims against all parties to such actions or  proceedings,
including claims against parties who are not parties to this Agreement.

     This waiver is  knowingly,  willingly and  voluntarily  made by each of the
parties hereto, and the parties hereby represent that no representations of fact
or opinion  have been made by any  individual  to induce this waiver of trial by
jury  or to in any way  modify  or  nullify  its  effect.  The  parties  further
represent  that they have been  represented in the signing of this Agreement and
in the making of this waiver by independent legal counsel, selected of their own
free will,  and that they have had the  opportunity  to discuss this waiver with
counsel.

     SECTION 11.16 Liability of the Lender.  The Borrowers hereby agree that the
Lender shall not be chargeable for any negligence,  mistake,  act or omission of
any accountant,  examiner, agency or attorney employed by the Lender (except for
the  gross  negligence  or  willful  misconduct  of  any  person,   corporation,
partnership  or other  entity  employed by the  Lender) in making  examinations,
investigations  or  collections,   or  otherwise  in  perfecting,   maintaining,
protecting or realizing upon any lien or security interest or any other interest
in the Collateral or other security for the Obligations.

     SECTION 11.17  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
APPLICABLE  STATE LAW),  THE RULES OF PRACTICE AND PROCEDURE FOR  ARBITRATION OF
COMMERCIAL DISPUTES OF ENDISPUTE, INC., D/B/A J.A.M.S./ENDISPUTE ("J.A.M.S.")

<PAGE>

AND THE "SPECIAL RULES" SET FORTH BELOW. IN THE EVENT OF AN  INCONSISTENCY,  THE
SPECIAL RULES SHALL CONTROL.  JUDGMENT UPON ANY ARBITRATION AWARD MAY BE ENTERED
IN ANY COURT HAVING  JURISDICTION.  ANY PARTY TO THIS  INSTRUMENT,  AGREEMENT OR
DOCUMENT MAY BRING ANY ACTION,  INCLUDING A SUMMARY OR EXPEDITED PROCEEDING,  TO
COMPEL ARBITRATION OF ANY CONTROVERSY OR CLAIM TO WHICH THIS NOTE RELATES IN ANY
COURT HAVING JURISDICTION OVER SUCH ACTION.

     (A) SPECIAL RULES.  THE  ARBITRATION  SHALL BE CONDUCTED IN FAIRFAX COUNTY,
VIRGINIA  AND  ADMINISTERED  BY  J.A.M.S.  WHO WILL  APPOINT AN  ARBITRATOR.  IF
J.A.M.S. IS UNABLE OR LEGALLY PRECLUDED FROM ADMINISTERING THE ARBITRATION, THEN
THE AMERICAN  ARBITRATION  ASSOCIATION WILL SERVE. ALL ARBITRATION HEARINGS WILL
BE COMMENCED WITHIN NINETY (90) DAYS OF THE DEMAND FOR ARBITRATION; FURTHER, THE
ARBITRATOR  SHALL  ONLY,  UPON A SHOWING OF CAUSE,  BE  PERMITTED  TO EXTEND THE
COMMENCING OF SUCH HEARING FOR AN ADDITIONAL SIXTY (60) DAYS.

         (B) RESERVATION OF RIGHTS. NOTHING IN THIS NOTE SHALL BE DEEMED TO: (I)
LIMIT THE  APPLICABILITY OF ANY OTHERWISE  APPLICABLE  STATUTES OF LIMITATION OR
REPOSE AND ANY WAIVERS CONTAINED IN THIS INSTRUMENT,  AGREEMENT OR DOCUMENT;  OR
(II) BE A WAIVER BY THE  LENDER OF THE  PROTECTION  AFFORDED  TO IT BY 12 U.S.C.
ss.91 OR ANY SUBSTANTIALLY EQUIVALENT STATE LAW; OR (III) LIMIT THE RIGHT OF THE
LENDER: (A) TO EXERCISE SELF HELP REMEDIES SUCH AS (BUT NOT LIMITED TO) SET OFF,
OR (B) TO FORECLOSE AGAINST ANY REAL OR PERSONAL PROPERTY 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 SELF HELP  REMEDIES  NOR THE
INSTITUTION OR MAINTENANCE OF ANY ACTION FOR  FORECLOSURE OR FOR  PROVISIONAL OR
ANCILLARY  REMEDIES  SHALL  CONSTITUTE  A  WAIVER  OF THE  RIGHT  OF ANY  PARTY,
INCLUDING  THE  CLAIMANT  IN  SUCH  ACTION,  TO  ARBITRATE  THE  MERITS  OF  THE
CONTROVERSY OR CLAIM OCCASIONING RESORT TO SUCH REMEDIES.

     SECTION  11.18 Right of  Contribution.  The  Borrowers and the Lender agree
that on and after the Closing Date, each Borrower (an "Entitled Borrower") shall
be entitled to contribution from each other Borrower to the extent, if any, that
(a) an  Entitled  Borrower  incurs any  Obligations  in excess of such  Entitled
Borrowers Net Valuation (as hereinafter defined) or (b) the Obligations incurred
by  such  Entitled   Borrower  would  leave  such  Entitled   Borrower  with  an
unreasonably small

                                       40

<PAGE>

amount of capital to enable the  Entitled  Borrower to operate  the  business in
which it is engaged,  and/or the Obligations  incurred by such Entitled Borrower
prevent  such  Entitled  Borrower  from  paying its debts as such debts  mature;
provided,  however, that such right of contribution shall be subordinated to the
payment of the Obligations and may not be exercised by any Borrower until all of
the Obligations have been paid in full.  Nothing in this Section shall be deemed
to in any manner impair the joint and several liability of each Borrower for any
and all of the Obligations.  The provisions of this Section shall be in addition
to and shall in no manner  limit any other rights of  contribution  available to
any Borrower.  The term "Net Valuation" as used in this Section means the amount
by which (1) an Entitled  Borrower's  property at a fair  valuation  exceeds (2)
such Entitled Borrower's debts.

     IN WITNESS  WHEREOF,  the  parties  hereto  have  signed  and  sealed  this
Agreement on the day and year first above written.

                               FIRST AMENDMENT TO
                        FINANCING AND SECURITY AGREEMENT

         THIS FIRST AMENDMENT TO FINANCING AND SECURITY AGREEMENT (this
"Agreement") made as of the 30th day of April, 1997 by and among VERSAR, INC., a
corporation  organized  under the laws of the State of Delaware  ("Versar")  and
GEOMET TECHNOLOGIES,  INC., a corporation  organized under the laws of the State
of  Delaware  (collectively,   the  "Borrowers"  and  each  a  "Borrower"),  and
NATIONSBANK,  N.A., a national banking  association,  its successors and assigns
(the "Lender").

                                    RECITALS

     A. The Borrowers are parties to a certain Financing and Security Agreement,
along with the Lender dated March 31, 1997 (as thereafter amended,  modified and
renewed from time to time,  the  "Financing  Agreement"),  pursuant to which the
Lender has agreed to make  available to the  Borrowers a guidance line of credit
in the maximum principal amount of Five Million Dollars  ($5,000,000) to be used
by the  Borrowers  to finance  Permitted  Acquisitions  and a  revolving  credit
facility in the maximum  principal amount of Three Million Dollars  ($3,000,000)
to be used by the Borrowers to finance  Receivables  all as more fully described
in the Financing  Agreement.  Unless otherwise  defined herein,  all capitalized
terms used herein shall have the meanings  given to such terms in the  Financing
Agreement.

     B. The Borrowers have requested that the Lender make an Acquisition Loan in
the amount of Two Million Dollars  ($2,000,000) for the purpose of acquiring not
less than seventy percent (70%) of the issued and  outstanding  stock of Science
Management Corporation,  a Delaware corporation (together with its subsidiaries,
"SMC") and to amend the  Financing  Agreement in  accordance  with the terms and
conditions set forth below.

                                        1

     NOW, THEREFORE,  in consideration of the foregoing,  and for other good and
valuable  consideration,   the  receipt  and  sufficiency  of  which  is  hereby
acknowledged,  the  Borrowers  and the  Lender do hereby  agree as  follows:

     1.  Recitals.  The  parties  hereto  acknowledge  and agree  that the above
Recitals  are true and correct in all  material  respects  and that the same are
incorporated herein and made a part hereof by reference.

     2.  Borrowing  Base.  Subject to the terms and  conditions set forth herein
from the date hereof  through the earlier of: (i) October 31, 1997,  or (ii) the
date on which Versar closes on the sale of its  operations  located in the State
of Utah (such date being called,  the "Borrowing  Base  Conversion  Date"),  the
parties  hereto  agree  that the  definition  of  "Borrowing  Base" set forth in
Section 1.01 of the Financing  Agreement shall be as follows:

          "Borrowing Base" means the sum of (a) ninety percent (90%) of Eligible
     Government  Receivables,  plus (b) eighty  five  percent  (85%) of Eligible
     Subcontractor   Receivables,   plus  (c)  eighty   percent  (80%)  Eligible
     Commercial  Receivables,  plus (d) the lesser of (i) fifty percent (50%) of
     Eligible Unbilled Borrowing Base Receivables, or (ii) $1,500,000, minus the
     sum of (y) the then outstanding  balance of the Acquisitions Notes, and (z)
     the then outstanding balance of the Sarnia Note.

From and after the Borrowing Base Conversion Date, the parties hereto agree that
without  further  notice to the Borrowers,  the  definition of "Borrowing  Base"
shall automatically be as follows:

          "Borrowing Base" means the sum of (a) ninety percent (90%) of Eligible
     Government  Receivables,  plus (b) eighty  five  percent  (85%) of Eligible
     Subcontractor   Receivables,   plus  (c)  eighty   percent  (80%)  Eligible
     Commercial Receivables, less the sum of (y) the then outstanding balance of
     the Acquisitions  Notes, and (z) the then outstanding balance of the Sarnia
     Note.

From and  after  the date  hereof,  for  purposes  of the  Financing  Agreement,
"Eligible Unbilled Borrowing Base Receivables@ means all Accounts arising out of
work actually performed by either

                                        2

<PAGE>

Borrowers  which (i) are eligible to be billed in accordance with the applicable
contract within thirty (30) days of the Aas of@ date of the applicable Borrowing
Base Certificate (with no additional  performance required by any Person, and no
condition to payment by the account debtor, other than receipt of an appropriate
invoice). The Borrowers understand and agree that any sums outstanding under the
Revolving  Loan in excess of the Borrowing Base shall be due and payable in full
on demand.

     3.  Period to  Complete  Acquisition.  None of the  Accounts  of SMC may be
included by the Borrowers in the  calculation  of the Borrowing  Base until such
date as the  Borrowers  satisfy  the  requirements  of  Sections 4 and 5 of this
Agreement  and  all of the  following  conditions  have  been  satisfied  in the
Lender's  sole and  absolute  discretion  (such date being  called the  "Joinder
Date"):

          (a) The Lender shall have received from the Borrower evidence that all
     of the unsecured  bankruptcy creditors of SMC have either been paid in full
     and fully released their liens on any and all of the assets of SMC, or have
     entered into one or more  subordination  agreements  in form and  substance
     satisfactory in all respects to the Lender and its counsel.

          (b) The Borrowers  shall have provided the Lender with fully  executed
     Subordination Agreements by and among Versar, SMC, and any and all existing
     secured   administrative   claim  lienholders  of  SMC  (the  "Subordinated
     Creditors")  and the  Lender  in form  and  substance  satisfactory  in all
     respects  to  the  Lender  and  its  counsel  (the  "Administrative   Claim
     Subordination").

From and after the Joinder Date,  all Accounts of SMC which in the Lender's sole
and  absolute  discretion  meet  the  Eligibility  Standards  and are  otherwise
acceptable to the Lender in its sole and absolute discretion, may be included by
the Borrowers in the Borrowing Base.

                                        3

<PAGE>

     4. Joinder of SMC. As soon as possible, but in no event later than June 30,
