PART I

ITEM 1.   BUSINESS

INTRODUCTORY NOTE

      On March 22,  1999,  the  Company  announced  that its Board of  Directors
authorized  the  repurchase of up to 1,500,000  shares of the  Company's  common
stock.  The  purchases  will be made from time to time in the open  market or in
privately negotiated transactions.

      On March 2, 1999, certain of the Company's domestic  subsidiaries (Putnam,
Hayes & Bartlett,  Inc., Hagler Bailly  Consulting,  Inc., TB&A Group, Inc., and
Theodore  Barry &  Associates)  were merged  with and into a newly  incorporated
Delaware  corporation,  PHB Hagler Bailly,  Inc., through which the Company will
provide its commercial rate consulting activities.

      On February 8, 1999, the Company acquired all of the outstanding  stock of
Lacuna Consulting Limited, a United Kingdom corporation,  in exchange for 65,000
shares of the Company's common stock.

      On November 20, 1998, the Company completed a new, three-year, $50 million
revolving  credit  facility  with  NationsBank,  N.A., a  subsidiary  of Bank of
America.  This credit facility  replaced  Hagler Bailly's $15 million  revolving
line of credit and Putnam, Hayes & Bartlett, Inc.'s $4 million revolving line of
credit.

      On November 17, 1998,  the Company  completed the  acquisition  of certain
assets of The  Fieldston  Company  ("TFC") and all of the  outstanding  stock of
Fieldston Publications, Inc. ("FPI"). Total consideration of the acquisition was
approximately  $2.3 million in cash and 232,558  shares of Hagler  Bailly common
stock. The acquisition was accounted for using the purchase method. Accordingly,
the consolidated  financial  statements reflect the results of operations of TFC
and FPI  since the date of  acquisition.  As a result  of the  transaction,  the
Company recorded intangible assets of approximately $4.8 million.



GENERAL

The predecessor of the Company was founded in 1980 as Hagler,  Bailly & Company,
Inc. In July 1984, RCG International,  Inc. ("RCG"),  an indirect  subsidiary of
Reliance Group  Holdings,  Inc.,  acquired the Company,  and in 1987 was renamed
RCG/Hagler Bailly,  Inc. In May 1995, the management of RCG/Hagler Bailly,  Inc.
completed the purchase of RCG/Hagler Bailly,  Inc. from RCG and the successor to
RCG/Hagler Bailly, Inc. became a wholly owned subsidiary of the Company. In July
1997, the Company completed its initial public offering.

      For  almost  20 years the  Company  has  maintained  its  industry  focus,
providing consulting,  research and other professional services to corporate and
government clients in energy, network industries and the environment.

      The  Company  believes  that  several  factors  distinguish  it  from  its
competitors.  In addition  to industry  focus,  its full  service  capabilities,
existing global infrastructure,  established client relationships, public sector
insight,  knowledge base and  experienced  team of management  and  consultants,
position it to capitalize on the growing demand for consulting services in these
industries.

BUSINESS MODEL

      The Company provides  solutions  custom-tailored  to the client's needs by
combining content, including proprietary research and industry information, with
superior  consulting  processes.  The  Company  then  offers  resources  such as
information technologies needed to implement and sustain the solution,  creating
tangible long-term value for the client.

      Through PHB Hagler  Bailly,  Inc.  ("PHB Hagler  Bailly"),  a wholly-owned
subsidiary  of the  Company,  it provides  strategic  advice and  analysis  that
assists  decision makers in business and  governments in developed  countries as
they solve issues involving energy,  telecommunications,  transportation,  water
resources,  the environment,  litigation and other matters.  PHB Hagler Bailly's
consulting   professionals  have  first-hand   experience  in  developing  sound
strategies and applying  business  principles that focus on the unique issues of
each client matter and increase  enterprise value. PHB Hagler Bailly has been at
the forefront of assessing  market  strength,  providing  asset  valuations  and
performance measurements,  analyzing competition, measuring risks, and improving
financial and operating performance.

      Through Hagler Bailly Services,  Inc. ("Hagler Bailly Services"),  another
wholly-owned  subsidiary  of the Company,  it provides  advisory  and  technical
services  to  public  sector  clients   worldwide  in  the  energy  and  network
industries, particularly transportation, water, and telecommunications,  and the
environment.  In addition to U.S. federal and state  governments,  Hagler Bailly
Services assists  multilateral and bilateral donor and financial  organizations,
foreign  governments,  and selected  private  clients in emerging or  developing
markets.  Hagler  Bailly  Services'  consulting  experts  provide  public policy
assistance  by advising  governments  and business  leaders on the  evolution of
specific policies in each country and construct a global view of policy reforms.
Hagler  Bailly  Services  has been at the  forefront  of  developing  policy and
pricing frameworks,  formulating  national and provincial strategy and planning,
drafting laws and regulations,  managing the transition to competitive  markets,
promoting  investment and business  creation,  evaluating  assets, and promoting
sustainable development.

SERVICE OFFERINGS

      The Company offers its clients a broad array of consulting services,  from
assisting in shaping the clients' vision through strategic planning to selection
of appropriate  solutions,  implementation  and on-going  management advice. The
Company's  services are delivered to clients  worldwide  primarily through seven
specialized  practices focused on energy,  including electric and gas utilities;
network   industries,    including   fuels,   water,    telecommunications   and
transportation; and the environment.

      These seven specialized practices are:

o        The Strategy practice  provides  strategic counsel and related services
         to the  executive  leadership  of energy and other  network  companies.
         Hagler Bailly has carefully developed methods that increase shareholder
         value in an environment  of rapid industry  change and new pressures on
         financial  performance.  Each  method  is a  discipline  to help  guide
         executives to value creation.

o        The   Management   and   Operations   practice   advises   utility  and
         telecommunications  companies on all aspects of business management and
         operations.  Hagler Bailly is experienced in helping clients understand
         and respond to both the internal  operational and external customer and
         market challenges that affect businesses today.

o        The Economics & Analytics  practice  provides  practical and innovative
         solutions  to  economic  problems,   providing  economic  analysis  and
         analytical tools to support  strategic  decision making.  Hagler Bailly
         offers a unique combination of academic rigor and hands-on professional
         experience to advise clients on regulatory economics, policy evaluation
         and business strategy.

o        The Market and Survey Analysis practice provides a full range of market
         research and survey  analysis that clients need in order to solve their
         mission-critical  business  problems.  Hagler Bailly helps clients gain
         insight on their customers,  competitors,  and the changing dynamics of
         their market through  state-of-the-art  study design,  quantitative and
         qualitative data collection, and analysis.

o        The Litigation Support practice assists law firms and corporate counsel
         with  litigation,   mediation,   and  arbitration  matters,   including
         liability  and   causation   issues,   determination   of  damages  and
         prejudgment interest,  litigation strategy and settlement negotiations.
         Hagler  Bailly  provides  economic  and  business  analysis  and expert
         testimony on liability and damages  issues in some of the largest civil
         litigation cases of recent decades.

o        The IT practice delivers information technology consulting services and
         solutions to electric,  gas and water utilities,  and service providers
         in the US and Canada.  The Company  provides these services through its
         exclusive  joint  venture,  Cap Gemini Hagler Bailly LLC, which designs
         information  technology  frameworks that pass  information  efficiently
         between and among organizations of all shapes and sizes.

o        The Environment  Management practice assists domestic and international
         clients manage environmental issues and prevent environmental problems,
         whether  of  local,   regional,   and/or   global  impact  by  offering
         environmental economics, scientific,  managerial and technical research
         and services.

     These  specialized  practices  are  designed  to work  together  to provide
clients the full range of services  and  capabilities  of the  Company.  From an
operational  standpoint,  the Company  regularly  reviews  and, as  appropriate,
restructures  these practice areas and services to address the changing business
problems, strategic alternatives and policy issues of its clients.

      In 1998,  the Company  provided its services to more than 1,150 clients in
both the private and public sectors.

COMPETITION

      The market for consulting  services in the energy,  network industries and
the environment is intensely competitive, highly fragmented and subject to rapid
change.  The market  includes a large number of  participants  from a variety of
consulting  market  segments,  both in the United  States  and  internationally,
including  general  management  consulting  firms,  the consulting  practices of
accounting firms,  consulting engineering firms, technical and economic advisory
firms and market research firms.  Many information  technology-consulting  firms
also maintain significant energy,  network industry and environmental  practices
and  others  may enter  the field in the  future.  Many of these  companies  are
national and  international in scope and may have greater  financial,  technical
and marketing resources than the Company.

      Hagler Bailly  believes that it is in a strong position to compete in this
market.  The Company  believes that several factors  distinguish it from many of
its current and potential competitors in the consulting industry.

o        Industry Focus. Since its inception in 1980, the Company has maintained
         its focus on  providing  a broad  array of  consulting  services to the
         energy,   network   industries   and  the   environment.   This   focus
         differentiates  the Company from general  management  consulting  firms
         that serve a full range of industries and firms with limited skill sets
         and  capabilities.  The Company  believes  that the insights  gained by
         working   worldwide  allow  it  to  customize   leading-edge-consulting
         concepts and tools to specific  situations  and thus  provide  tangible
         value, rather than just theories, to its clients.

o        Full Service  Capabilities.  The Company's  strategy is to partner with
         its  clients  in  conceptualizing  and  implementing  solutions,  which
         significantly  increase  enterprise value, by building a broad range of
         consulting platforms enabling it to meet its clients' consulting needs.
         These  include  corporate  strategy,   marketing  and  sales,   product
         development,   energy  supply  and  logistics,  operations  management,
         information systems and technology, economic analysis and environmental
         management.  In addition,  the Company conducts its own market research
         using  a   state-of-the-art   survey  center   equipped  with  26  CATI
         (Computer-Assisted Telephone Interview) stations.

o        Existing Global Infrastructure.  The Company operates from 12 principal
         offices in the United  States at the  following  locations:  Arlington,
         Virginia;  Boulder,  Colorado;   Cambridge,   Massachusetts;   Chicago,
         Illinois;  Houston,  Texas;  Los Angeles,  California (two  locations);
         Madison,  Wisconsin;  New York, New York;  Palo Alto,  California;  San
         Francisco,  California  and The  District of  Columbia  and from eleven
         principal  locations  abroad in the  following  cities:  Buenos  Aires,
         Argentina;  Daventry,  England;  Dublin, Ireland;  Jakarta,  Indonesia;
         Islamabad,  Pakistan;  Melbourne,  Australia;  London,  England; Paris,
         France;  San Paulo,  Brazil;  Sydney,  Australia;  Toronto,  Canada and
         Wellington, New Zealand.

o        Established Client  Relationships.  In the year ended 1998, the Company
         received repeat business from  approximately 42% of the clients who had
         engaged the Company in the year ended 1997.  Further, in the year ended
         1998,  revenues  from  clients  served  in the  year  ended  1997  were
         approximately 60% of the Company's total revenues.  Over the past year,
         the clients have included  approximately  220 electric or gas utilities
         located throughout the world and four international  development banks.
         Relationships with clients, many of which date back over a decade, span
         various  levels within  client  organizations,  ranging from  corporate
         boards,  chief  executive  officers  and  other  senior  management  to
         functional managers.

o        Public Sector  Insight.  The Company has worked with a number of public
         sector   organizations,   including   the  United   States  Agency  for
         International   Development  ("USAID"),  the  Environmental  Protection
         Agency,   the  European  Union,  the  U.K.  Knowlton  Fund,  the  Asian
         Development  Bank and the World  Bank for many  years.  This  gives the
         Company a special perspective on the energy,  utility and environmental
         industries and enhances the Company's reputation and ability to compete
         successfully for consulting business.

o        Knowledge  Base.  The Company has developed an extensive  knowledge and
         information  base. The Company owns several  proprietary  databases and
         software  packages  --  OPECSM  and  NPESM,  two  nuclear  power  plant
         operations  databases,  and IPPSM, a worldwide  information database on
         independent power producers.  The Company has recently developed and is
         aggressively  marketing its proprietary database,  RampUpSM, to provide
         clients with  unprecedented  information on U.S. utility operations and
         cost structure.  Finally,  through the Company's  proprietary  Business
         Information  and Knowledge  Exchange  Intranet  ("BIKEnetSM"),  Company
         personnel have direct access to the Company's proprietary knowledge and
         warehouse of  information.  This system is  accessible  from all of the
         Company's offices.

o        Experienced   Team  of  Management  and   Consultants.   The  Company's
         management  and  senior  consultants  have  a  wide  range  of  energy,
         telecommunications,   transportation   and   environmental   consulting
         expertise and experience.  In addition,  many of the senior  management
         and consultants have worked extensively with one another.  Management's
         average  tenure  with the  Company  is  approximately  13  years.  This
         consistency of leadership and teamwork, combined with training provided
         by the  Company,  has  fostered a strong  company  culture and employee
         loyalty.

o        Established Global Visibility. The Company's staff frequently publishes
         articles  and  is  invited  to  present  at  industry   gatherings  and
         conferences.  The staff is also active in several  industry  groups and
         professional  associations  including elected or appointed positions to
         the  United  States  Energy   Association   (member  of  the  Board  of
         Directors),  the National Coal Council  (member) and the Association of
         Energy Services Professionals (member of the Board of Directors).

      As a result of these  competitive  factors,  the  Company  believes it has
emerged as one of the leading management consulting firms focused on energy, the
network and environmental industries.

MARKETING AND SALES

      The Company  markets its  services  from its  headquarters  in  Arlington,
Virginia and through each of its  subsidiaries.  The Company employs a number of
business  development and marketing  strategies to communicate  with prospective
and current  clients,  including,  but not limited  to,  on-site  presentations;
industry  seminars  featuring  persentations  by the  Company's  management  and
consultants;  speeches;  articles in  industry,  business,  economic,  legal and
scientific journals; and through other publications and press releases regarding
the energy, network and environment industries and the Company's methodologies.

      A  significant  portion  of the new  business  arises  from  prior  client
engagements.  The Company often leverages the client  relationships  of firms it
acquires by cross-selling its existing services.  Clients often expand the scope
of engagements during delivery to include follow-on complementary activities.

      Also, the Company's  on-site  presence  affords it opportunities to become
aware of,  and to help  define,  additional  project  opportunities  as they are
identified  by the  client.  Strong  client  relationships  arising  out of many
engagements   often  facilitate  the  Company's  ability  to  market  additional
capabilities to its clients in the future.

     The  Company  establishes  a  client  development  goal  for  each  of  its
consulting  officers and principals and  systematically  reviews  individual and
group  performance  against  these goals.  The  Company's  compensation  system,
particularly  in the award of bonuses and stock  options,  is  weighted  towards
success in meeting these client development goals.

o        Commercial Sector Clients. In the commercial sector, client acquisition
         techniques  include  referrals and focused  presentations  to boards of
         directors,  chief executive and operating officers and other executives
         of  prospective  client  companies.  Presentations  generally  focus on
         opportunities  in the market  segments most relevant to the prospective
         clients,  examples of the Company's previous work in related industries
         and the Company's international capabilities.

o         Public Sector Clients.  In the public sector,  contracts are awarded
          primarily on the basis of  competitive  solicitation.  The Company has
          developed  strong  capabilities  to prepare  proposals that respond to
          complex requests and often require the integration and coordination of
          the services of several  subcontractors  and independent  consultants.
          The Company has also developed a detailed  understanding of government
          and other institutional  procurement  regulations in the United States
          and  internationally.  In  addition,  in  order to  obtain  government
          contracts,  consultants must adhere to stringent cost,  accounting and
          regulatory  controls.  In order to comply with such requirements,  the
          Company  regularly holds training  seminars to ensure  compliance with
          applicable   government   regulations   and   uses   a   sophisticated
          computer-based  accounting  system  that  allows it to track  costs in
          adherence  to  government  standards.  The Company  also meets  public
          sector clients' cost guidelines through competitive pricing.


HUMAN RESOURCES

      As of  December  31,  1998,  the  Company's  personnel  consisted  of  780
full-time employees.

      The Company supplements its consultants on certain engagements with highly
skilled  independent  contractors.  The Company  believes  that its  practice of
retaining  independent  contractors on a  per-engagement  basis provides it with
greater  flexibility in adjusting  professional  personnel levels in response to
changes in demand for its services.

RISK FACTORS

      Attraction,  Retention and Management of Professional  and  Administrative
Staff. The Company's business involves the delivery of professional services and
is labor intensive.  The Company's future performance depends in large part upon
its ability to attract, develop, motivate and retain highly skilled consultants,
research associates and administrative staff,  particularly senior professionals
with business development skills.

      In connection  with its recruiting  efforts,  the Company seeks  employees
from top graduate schools with prior relevant  consulting  experience and strong
project  management,  analytic  and  communications  skills in  competitive  and
regulated industries, especially those with meaningful international experience.
The Company also hires  professionals with senior executive  experience directly
from industry.

      Qualified  consultants  are in great  demand,  and  there  is  significant
competition for employees with these skills from other consulting and investment
banking  firms,   research  firms,  energy  companies  and  many  other  related
enterprises.  Although the Company  attracts and motivates its  professional and
administrative staff by offering competitive packages of base and incentive cash
compensation,  stock  options,  bonuses and attractive  benefits,  many of these
firms have greater financial  resources than the Company,  which they may use to
attract and compensate qualified  personnel.  There can be no assurance that the
Company will be able to attract and retain sufficient  numbers of highly skilled
consultants in the future.  The loss of the services of a significant  number of
consultants,  research  associates  or  administrative  personnel  could  have a
material  adverse  effect  on the  Company's  business,  operating  results  and
financial condition, including its ability to secure and complete engagements.

      Concentration  of  Revenues.  Over half of the revenues of the Company are
derived from private and institutional  clients involved in the energy,  network
and environmental industries. As a result of this focus, the Company's business,
financial  condition  and  results  of  operations  are  influenced  by  factors
affecting these industries,  including,  but not limited to, changing political,
economic and regulatory influences that may affect the procurement practices and
operations of such  industries.  In particular,  many electric and gas utilities
are consolidating to create larger organizations or strategic  alliances.  These
consolidations  and alliances will reduce the number of potential  customers for
the Company and may also  create  conflicts  of  interest  between  clients.  In
addition,  these  consolidations  and alliances may result in the acquisition of
certain  of the  Company's  key  clients,  and such  clients  may scale  back or
terminate  their  relationship  with the Company  following  their  acquisition.
Similarly,  cutbacks  in the energy,  network  industries  and/or  environmental
budgets of the United  States and other  governments  could  result in the scale
back or termination of some of the Company's public sector contracts. The impact
of these developments in the energy,  utility,  transportation and environmental
industries is difficult to predict and could have a material  adverse  effect on
the Company's business, financial condition and results of operations.



      Ability to Sustain and Manage Growth.  The Company has  experienced  rapid
growth in  recent  years.  The  Company  completed  five  acquisitions  in 1998,
including  the  acquisition  of Putnam,  Hayes and  Bartlett,  Inc.  The Company
believes that sustaining  such growth places a strain on operational,  human and
financial resources. In order to manage its growth, the Company must continue to
improve  its  operating  and  administrative  systems  and to attract and retain
qualified  management  and  professional,   scientific  and  technical-operating
personnel.   Foreign  operations  also  may  involve  the  additional  risks  of
assimilating  differences in foreign  business  practices,  hiring and retaining
qualified  personnel,  and overcoming language barriers.  Failure to manage such
growth  effectively  could  have a  material  adverse  effect  on the  Company's
business.

      Risks  Related to  Possible  Acquisitions.  An  element  of the  Company's
strategy is to expand its operations  through the  acquisition of  complementary
businesses. There can be no assurance that the Company will be able to identify,
acquire,  profitably  manage or successfully  integrate any acquired  businesses
into the Company without  substantial  expenses,  delays or other operational or
financial  problems.  Moreover,  competitors of the Company are also  soliciting
acquisition  candidates,  which  could  result  in an  increase  in the price of
acquisition  targets  and a  decrease  in the  number  of  attractive  companies
available for acquisition. Further, acquisitions may involve a number of special
risks,  including  diversion of  management's  attention,  failure to retain key
acquired  personnel,   increased  costs  to  improve  managerial,   operational,
financial and  administrative  systems,  unanticipated  events or circumstances,
legal  liabilities,  increased  interest  expense and  amortization  of acquired
intangible  assets,  some or all of which could have a materially adverse impact
on the Company's  business,  operating results and financial  condition.  Client
satisfaction  or  performance  problems at a single  acquired  firm could have a
materially  adverse  impact on the  reputation  of the  Company  as a whole.  In
addition,  there can be no assurance  that  acquired  businesses,  if any,  will
achieve anticipated revenues and earnings.  The failure of the Company to manage
its acquisition  strategy  successfully  could have a material adverse effect on
Hagler Bailly's business, operating results and financial condition.

      Dependence on Key Clients.  The Company  derives a significant  portion of
its revenues from a relatively limited number of clients. For example,  revenues
from the Company's ten most significant clients accounted for approximately 39%,
35% and 42% of its total revenues in 1998, 1997 and 1996,  respectively.  A U.S.
government  agency,  USAID,  is the Company's  largest  client,  accounting  for
approximately  22%, 20% and 18% of Hagler  Bailly's total revenues in 1998, 1997
and 1996,  respectively.  Clients  typically  retain the Company as needed on an
engagement basis rather than pursuant to long-term  contracts,  and a client can
usually  terminate  an  engagement  at any time without a  significant  penalty.
Moreover,  there can be no assurance  that the Company's  existing  clients will
continue to engage it for  additional  assignments  or do so at the same revenue
levels.  The loss of any significant client could have a material adverse effect
on the Company's  business,  results of operations and financial  condition.  In
addition,  the  level  of  the  Company's  consulting  services  required  by an
individual  client  can  diminish  over  the life of its  relationship  with the
Company,  and there can be no assurance  that the Company will be  successful in
establishing relationships with new clients as this occurs.



      Professional and Other Liability.  The Company's services involve risks of
professional  and  other  liability.  If the  Company  were  found to have  been
negligent  or to have  breached  its  obligations  to its  clients,  it could be
exposed  to  significant  liabilities  and its  reputation  could  be  adversely
affected. In connection with many of its public sector engagements,  the Company
employs the  services of local staff and uses  consultants  who are  independent
contractors.   Negligent  or  illegal  acts,  or  ethical  violations  by  these
independent contractors could adversely affect the Company.

      Public  Sector  Market and  Contracting  Risks.  Approximately  31% of the
Company's  total revenues in 1998 and 34% in 1997 were derived from contracts or
subcontracts with public sector clients. Providing consulting services to public
sector  clients  is  subject  to  detailed  regulatory  requirements  and public
policies as well as to funding priorities.  Contracts with public sector clients
may be conditioned  upon the continuing  availability of public funds,  which in
turn depends upon lengthy and complex budgetary  procedures,  and may be subject
to certain pricing constraints.  Moreover, public sector contracts may generally
be  terminated  for a  variety  of  factors,  including  when it is in the  best
interests of the  respective  government.  There can be no assurance  that these
factors or others unique to contracts with governmental entities will not have a
material  adverse  effect on the Company's  business,  results of operations and
financial condition.

      Intense  Competition.  The market for  consulting  services in the energy,
network  and the  environmental  industries  is  intensely  competitive,  highly
fragmented  and  subject  to rapid  change,  and such  competition  is likely to
increase  in  the  future.  Many  of  the  Company's  competitors  have  greater
personnel,  financial,  technical and marketing resources than the Company.  The
Company also competes with its clients' internal  resources,  particularly where
such resources  represent a fixed cost to the client. This source of competition
may  heighten  as  consolidation  of electric  and gas utility and other  energy
industry companies creates larger organizations.  There can be no assurance that
the Company will be able to compete  successfully with its existing  competitors
or with any new competitors.

      Risk of International Operations. The Company operates either permanent or
project  offices  in a total of 22 foreign  countries.  The  Company  expects to
continue to expand its international operations and offices primarily in Western
Europe, Latin America and the Pacific Rim. Expansion into new geographic regions
requires  considerable  management  and financial  resources and may  negatively
impact  the   Company's   near-term   results  of   operations.   The  Company's
international operations are subject to numerous potential challenges and risks,
including war, civil  disturbances,  other political and economic  conditions in
various jurisdictions such as tariffs and other trade barriers,  longer accounts
receivable  collection cycles,  fluctuations in currency and potentially adverse
tax consequences. There can be no assurance that such international factors will
not have a  material  adverse  effect  on the  Company's  business,  results  of
operations and financial condition.




      Dependence on Key Employees.  The Company's business consists primarily of
the delivery of professional  services and,  accordingly,  its future success is
highly dependent upon the efforts,  abilities,  business generation capabilities
and  project  execution  of its  consultants.  The  Company's  success  is  also
dependent upon the  managerial,  operational  and  administrative  skills of its
officers.  The loss of the  services  of any  consultant  or the  failure of the
Company's  consultants  to generate  business or  otherwise  perform at or above
historical  levels  could  have a  material  adverse  effect  on  the  Company's
business,  financial  condition and results of operations.  The Company does not
have  employment or  non-competition  agreements with many of its consultants or
officers;  accordingly,  such individuals may terminate their  relationship with
the Company at will and without notice and immediately begin to compete with the
Company.

       Concentration  of  Ownership.  As of March 1,  1999,  the  directors  and
executive officers of the Company  beneficially owned approximately 31.3% of the
Company's  outstanding  shares of common stock. As a result,  these stockholders
will  have  substantial  influence  over the  outcome  of  matters  requiring  a
stockholder  vote,  including  the  election  of the  members  of the  Board  of
Directors. Such control could adversely affect the market price of the Company's
common  stock or delay or prevent a change of control of the  Company at a price
which might represent a premium over the market price of its common stock.

      Need to Develop New Offerings. The Company's future success will depend in
significant  part on its  ability to  successfully  develop  and  introduce  new
service offerings and improved versions of existing service offerings. There can
be no assurance that the Company will be successful in  developing,  introducing
on a timely  basis and  marketing  such service  offerings,  or that any service
offerings will be accepted in the market.  Moreover,  services offered by others
may render the Company's services non-competitive or obsolete.

      Project Risks.  Many of the Company's  engagements  involve projects which
are critical to the  operations of its  customers'  businesses and which provide
benefits that may be difficult to quantify.  The Company's  failure or inability
to meet a customer's  expectations  in the  performance  of its  services  could
result in the incurrence by the Company of a financial loss and could damage the
Company's  reputation and adversely  affect its ability to attract new business.
In addition,  an unanticipated  difficulty in completing a project could have an
adverse effect on the Company's business and results of operations. Fees for the
Company's  engagements  can be  based on the  project  schedule,  the  Company's
staffing  requirements,  the level of customer  involvement and the scope of the
project as agreed upon with the customer at the project's inception. The Company
generally  seeks  to  obtain  an  adjustment  in its  fees in the  event  of any
significant  change in any of the assumptions  upon which the original  estimate
was  based.  However,  there  can be no  assurance  that  the  Company  will  be
successful in obtaining any such adjustment in the future.

      Intellectual  Property  Rights.  The  Company's  performance  is  in  part
dependent upon its internal  information and communication  systems,  databases,
tools,  and the methods and  procedures  that it has developed  specifically  to
serve its clients.  The Company  relies on a combination  of  nondisclosure  and
other contractual arrangements and copyright, trademark and trade secret laws to
protect its proprietary  systems,  information  and procedures.  There can be no
assurance that the steps taken by the Company to protect its proprietary  rights
will be adequate to prevent  misappropriation of such rights or that the Company
will be able to detect  unauthorized use and take  appropriate  steps to enforce
its proprietary rights. The Company believes that its systems and procedures and
other proprietary rights do not infringe upon the rights of third parties. There
can be no assurance,  however,  that third parties will not assert  infringement
claims  against  the  Company  in the  future or that any such  claims  will not
require  the  Company to enter into  costly  litigation  or  materially  adverse
settlements to litigation, regardless of the merits of such claims.

      Government  Regulation of Immigration.  Certain of the Company's employees
are foreign  nationals  working in the United  States  under U.S.  visas or work
permits. Congress and administrative agencies with jurisdiction over immigration
matters  have  periodically  expressed  concerns  over the  levels  of legal and
illegal immigration into the U.S. These concerns have often resulted in proposed
legislation,  rules and regulations aimed at reducing the number of work permits
that may be issued.  Any changes in such laws making it more  difficult  to hire
foreign  nationals  or limiting  the  ability of the  Company to retain  foreign
employees could require the Company to incur  additional  unexpected labor costs
and expenses.

      Fluctuations of Operating Results.  The Company's future operating results
will continue to be subject to quarterly  fluctuations based upon a wide variety
of  factors,  including  the  number  and  significance  of  client  engagements
commenced and completed during a quarter,  delays incurred in connection with an
engagement,  the  number of  business  days in a  quarter,  employee  hiring and
utilization  rates,  the  ability of clients to  terminate  engagements  without
penalties, the size and scope of engagements, the nature of the fee arrangement,
the seasonality of the spending cycle of public sector clients  (especially that
of the United States government),  the timing of new office openings,  return on
investment  capital,  and the general  economy,  such as  recessionary  periods,
political  instability,  changes in trade policies,  fluctuations in interest or
currency exchange rates and other competitive factors.  Seasonality also affects
the Company's  operating results,  particularly in the third and fourth quarters
of  each  fiscal  year.  In  addition,  the  Company's  operating  expenses  are
increasing  as the  Company  continues  to expand  its  operations,  and  future
operating  results  will be  adversely  affected  if  revenues  do not  increase
accordingly.  Additionally,  the Company plans to continue to evaluate and, when
appropriate,  make  acquisitions of  complementary  businesses.  As part of this
process the Company will continue to evaluate the changing  value of its assets,
and when necessary,  make adjustments thereto.  While the Company cannot predict
what  effect  these  various  factors  may have on its  financial  results,  the
aggregate  effect  of these  and  other  factors  could  result  in  significant
volatility in the Company's future performance and stock price.

      Fluctuations  in the  General  Economy.  The  general  level  of  economic
activity  significantly affects demand for the Company's  professional services.
When economic activity slows, clients may delay or cancel plans that involve the
hiring of  consultants.  The  Company is unable to predict the level of economic
activity at any particular  time, and  fluctuations in the general economy could
adversely  affect  the  Company's  business,  operating  results  and  financial
condition.

      Employment  Liability  Risks.  The Company,  as a provider of professional
services,  employs and places  individuals in the workplace of other businesses.
Inherent risks of such activity include possible claims of errors and omissions,
misuse   of  client   proprietary   information,   misappropriation   of  funds,
discrimination and harassment, theft of client property, other criminal activity
or torts and other claims. Although historically the Company has not experienced
any material  claims of these types,  there can be no assurance that the Company
will not experience such claims in the future.

      Certain   Anti-takeover   Effects.  The  Company's  Amended  and  Restated
Certificate of Incorporation,  By-laws, and the Delaware General Corporation Law
include  provisions  that may be deemed to have  anti-takeover  effects  and may
delay,  defer or prevent a takeover attempt that stockholders  might consider in
their best  interests.  These include a Board of Directors which is divided into
three classes, each of which is elected to serve staggered three-year terms, and
by-law  provisions  under which only the  President,  a majority of the Board of
Directors or stockholders owning at least 50% of the Company's capital stock may
call meetings of the  stockholders.  Also, the Board of Directors of the Company
is  authorized  to  issue up to  5,000,000  shares  of  preferred  stock  and to
determine the price, rights,  preferences and privileges of such shares, without
any further  stockholder  action. The existence of this "blank-check"  preferred
stock could render more  difficult or discourage an attempt to obtain control of
the Company by means of a tender  offer,  merger,  proxy  contest or  otherwise.
Furthermore,  the Company is subject to the anti-takeover  provisions of Section
203 of the Delaware  General  Corporation Law that prohibits  Hagler Bailly from
engaging in a "business combination" with an "interested stockholder" unless the
business  combination is approved in a prescribed manner. These provisions could
also have the  effect of  delaying  or  preventing  a change of  control  of the
Company, which could adversely affect the market price of the common stock.

      Fluctuations  in Stock  Price.  The market price of the  Company's  common
stock  may  fluctuate  substantially  due to a  variety  of  factors,  including
quarterly  fluctuations in results of operations,  announcements or terminations
of new services, offices, contracts,  acquisitions or strategic alliances by the
Company or its competitors,  as well as changes in the market  conditions in the
energy, network and environmental  industries,  changes in earnings estimates by
analysts, changes in accounting principles,  sales of the Company's common stock
by existing holders,  loss of key personnel,  a relatively small float of shares
that  are  freely  tradable  without   restriction  or  registration  under  the
Securities Act of 1933 and other factors. The stock market has from time to time
experienced  extreme  price  and  volume  fluctuations  that  have  particularly
affected the market price for many companies and which,  on occasion,  have been
unrelated to operating performance.  To the extent the Company's performance may
not meet  expectations  published by external  sources,  public  reaction  could
result in a sudden and  significantly  adverse impact on the market price of the
Company's  securities,  particularly on a short-term  basis.  In addition,  such
stock price  volatility  may provoke the  initiation of  securities  litigation,
which may divert substantial management resources and may have an adverse effect
on the  management  of business  operations.  Any of these  results could have a
material  adverse  effect  on the  Company's  business,  operating  results  and
financial condition.

      year ended December 31, 1994,  also includes  $1,802 of selling,  general,
      and administrative expenses, representing a note receivable from a related
      party, and the year ended December 31, 1996,  includes  approximately $500
      of cost of services,  representing  that  portion of officer  compensation
      that  exceeded  the  compensation  that  would  have  been  paid  had  the
      compensation plan adopted in January 1997 been in effect for all of 1996.
(3)   In  connection  with an  amendment  to the Hagler  Bailly,  Inc.  Employee
      Incentive and  Non-Qualified  Stock Option and Restricted  Stock Plan (the
      "Stock Option  Plan") and a  reclassification  of its common  stock,  each
      effective  December  31,  1996,  Hagler  Bailly  incurred   non-recurring,
      non-cash  charges to  operations  amounting  to  approximately  $4,600 for
      options and  approximately  $1,600 for stock in 1996. In connection with a
      stock bonus to an employee,  the Company incurred a non-cash  compensation
      charge to operations in the first quarter of 1997 of $65. PHB common stock
      issued or subject to issuance under subscriptions  receivable entered into
      within 12 months preceding the closing of the merger were presumed to have
      been  issued  in  contemplation  of  the  proposed  transaction  and  were
      accounted for at their fair market value at date of issuance. Accordingly,
      PHB recognized a non-recurring,  non-cash, non-tax deductible compensation
      charges for the years ended  December  31, 1997 and 1998 of  approximately
      $9,900 and $2,600,  respectively,  representing the difference between the

      be nonrecurring.  The effect of excluding  these nonrecurring  charges and
      extraordinary  gains on the Company's statement of operations, net of tax,
      would  increase  net  income  by  approximately $6,200, $8,600 and $9,000,
      to pro forma  operating net  income of  approximately  $3,400,  $6,700 and
      $15,700 for the years ended December 31, 1996,1997 and 1998, respectively.
      The effect of  excluding  the nonrecurring charges and extraordinary gains

      ended  December 31, 1996,  1997,  and 1998, respectively.  For purposes of
      the  increase in EPS  caused  by  the  exclusion  of certain  nonrecurring
     transactions discussed above, tax expense was applied at a combined federal
      and state  income tax rate of 40.0% for the year ended  December 31, 1996,
      47.6% for the year  ended December 31, 1997, and 39.7% for the  year ended
      December 31, 1998.

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

Overview

   The predecessor of the Company was founded in February 1980 as Hagler, Bailly
& Company, Inc. In July 1984, it was acquired by RCG International, Inc. ("RCG")
an indirect subsidiary of Reliance Group Holdings,  Inc. and in 1987 was renamed
RCG/Hagler Bailly,  Inc. In May 1995, the management of RCG/Hagler Bailly,  Inc.
completed the purchase of  RCG/Hagler  Bailly,  Inc.  from RCG (the  "Management
Buy-Out"),  and the successor to RCG/Hagler  Bailly,  Inc. became a wholly-owned
subsidiary of the Company. In July 1997, the Company completed an initial public
offering (the "IPO").

      Hagler  Bailly,  together with its wholly owned  subsidiaries,  PHB Hagler
Bailly,  Hagler  Bailly  Services and several of its other  domestic and foreign
wholly  owned  subsidiaries,  is a leading  worldwide  provider of  professional
services to corporate and government  clients on energy,  network industries and
the environment.

      The Company's revenues consist of consulting  revenues and other revenues.
Consulting  revenues  represent  revenues  associated with  professional  staff,
subcontractors and independent consultants, and client reimbursable expenses and
are associated with the Company's primary business of offering corporate clients
strategy and business  operations  consulting,  economic  counsel and litigation
support,  and market research and survey analysis.  Other revenues include those
derived  from  information-based   product  and  services,   financial  advisory
services, and publication of newsletters, reference manuals, and data series for
the energy and  transportation  industries  services.  The Company's client base
includes both the public and private sector.  Revenue from the private sector is
typically  characterized  by higher gross  margins than the public  sector,  yet
generally   requires  a  higher  relative  level  of   infrastructure   support.
Consequently,  the  Company's  operating  performance  is affected by its public
sector /  private  sector  business  mix.  Through  strategic  acquisitions  and
internal  growth,  the Company has increased its private sector client base, and
will continue to pursue such opportunities in the future.

      Total revenues  represent the total of all revenues  related to contracts,
including  revenues  associated  with  professional  staff,  subcontractors  and
independent  consultants.  Consulting  revenues represent the amount of contract
revenue   associated  with  billings  by  the  Company's   professional   staff.
Subcontractor   and  other   revenues   represent   revenues   associated   with
subcontractors  and  independent  consultants,  as well as  travel  and per diem
reimbursements from clients.

      The  Company  derives  substantially  all of its  revenues  from  fees for
professional  services.  Clients are typically  invoiced on a monthly basis. The
majority of revenues are billed at standard daily rates,  standard hourly rates,
or  cost-plus  fixed-fees.  Revenues  from  standard  daily rate  contracts  are
recognized at amounts  represented by the agreed-upon  billing amounts and costs
are recognized as incurred.  Revenues from standard hourly rate  engagements are
recognized as hours are recorded and costs are  recognized as they are incurred.
Revenue from cost-plus  fixed-fee  contracts is recognized as costs are incurred
on the  basis of  direct  costs  plus  allowable  indirect  costs and a pro rata
portion  of  estimated  fee.  The  remainder  of the  revenues  are  billed on a
fixed-bid basis and by lump sum fee  arrangements.  Revenues from fixed-bid type
contracts are  recognized on the  percentage-of-completion  method of accounting
with costs and  estimated  profits  included in contract  revenues  based on the
relationship that contract costs incurred bear to management's estimate of total
contract  costs.  Losses,  if any,  are accrued  when they become  known and the
amount of the loss is reasonably  determinable.  The Company's most  significant
expenses are project personnel costs,  which consist of consultant  salaries and
benefits  (including  bonuses),  and  travel-related  direct  project  expenses.
Project personnel are typically full-time professionals employed by the Company,
although the Company often  supplements its  professional  project staff through
the use of subcontractors and independent consultants. The Company believes that
retaining  subcontractors and independent  consultants on a per-engagement basis
provides it with greater flexibility and reduced risk in adjusting  professional
staff levels in response to changes in demand for its services.

Compensation Charges

      Effective December 31, 1996, the Company adopted an amendment to its Stock
Option Plan which  changed the  exercise  price of future  options to be granted
thereunder to the market value of the underlying  common stock. In addition,  in
connection  with  the   reclassification   of  its  common  stock,  the  Company
substituted  0.9 shares of Class A common stock for each share of Class B common
stock  underlying  971,963 options vesting on January 1, 1997. At the same time,
options to purchase 971,963 shares of Class B common stock vesting on January 1,
1998 were canceled. As a result, the Company recorded a non-recurring,  non-cash
charge to  operations  of  approximately  $6.2 million in December 1996 of which
approximately  $4.6  million  was for  options  to  purchase  common  stock  and
approximately  $1.6  million  was for  394,160  shares of common  stock  sold to
employees during 1996. These charges represent the aggregate  difference between
the exercise price of such  outstanding  options or the issuance price of common
stock sold to  employees  during  1996,  as the case may be,  and the  appraised
market value of the underlying common stock at December 31, 1996.

      The Company also recognized a non-recurring, non-cash charge to operations
of  approximately  $10.0  million  in the year  ended  December  31,  1997,  and
approximately  $2.6 million in the year ended  December 31, 1998.  These charges
are required under generally accepted accounting principles for stock issued, or
obligated  to be issued,  during the twelve  months  preceding  the closing of a
pending   merger  based  on  the   presumption   that  such  issuances  were  in
contemplation  of the merger.  Substantially  all of these costs were related to
the PHB merger and  represent  the  difference  between the fair market and book
value of PHB common stock  issuable under  subscriptions  within one year of the
merger's close.

Recent Mergers and Events

      On December 1, 1997, the Company  completed the merger of Apogee  Research

deliver  information  technology  consulting services and solutions to electric,
gas and water  utilities,  and service  providers  in the U.S.  and Canada.  The
Company  expects the joint venture,  Cap Gemini Hagler Bailly,  L.L.C.,  to turn
profitable  sometime late in the fiscal year ending December 31, 1999. The joint
venture is owned  equally by the  Company  and Cap Gemini  America  and each has
invested capital in the venture and transferred key senior  professionals to it.
Concurrently  with the  creation  of the joint  venture,  Cap  Gemini  purchased

economic and management consulting firm in the United States. The Company issued
6,548,953  shares of its common stock in exchange for all of the common stock of
PHB. The  business  combination  was  accounted  for as a pooling of  interests.
Accordingly,  the Company's  financial  statements have been restated to reflect

1998 COMPARED TO 1997

      Revenues for the year ended December 31, 1998, increased by $16.8 million,
or 10.5%,  to $177.5  million from the year ended  December  31,  1997.  Of this
increase,  $14.3  million was  attributable  to  consulting  revenues,  and $2.5
million was attributable to other revenues.  Consulting  revenues increased 9.0%
for the year ended December 31, 1998, as compared to the year ended December 31,
1997. This increase was primarily driven by the Company's focus on the growth of
private-sector  engagements  resulting  in an  increase  of $6.2  million and an
increase  internationally  of $8.1 million resulting from increased capacity and
capabilities  through the  purchase of Estudio Q, an  Argentinean  company,  and
growth in PT Hagler  Bailly  Indonesia,  Hagler Bailly  Pakistan,  Hagler Bailly
France, and IGA. Other revenues increased 143.6% for the year ended December 31,
1998, as compared to the comparable  period of the prior year. This increase was
attributable to increased revenues from information-based  products and services
associated with contracts the Company was awarded in the current fiscal year. In
the year ended December 31, 1998,  approximately 97.6% of the Company's revenues
were derived from consulting revenues,  as compared with 98.9% in the year ended
December 31, 1997.

      Cost of services for the year ended  December 31, 1998,  increased by $5.6
million,  or 4.7%, to $126.2 million from the year ended December 31, 1997. Cost
of services as a percentage of revenue  decreased from 75.1 % for the year ended
December 31, 1997, to 71.1% for the year ended December 31, 1998,  primarily the
result of a reduction in cash compensation resulting from the integration of the
Company's and merged firms' operations, particularly PHB.

      Selling,  general and administrative  expenses ("SG&A") for the year ended
December 31, 1998,  decreased by approximately  $1.8 million,  or 6.5%, to $25.1
million  from the year ended  December 31,  1997.  Expressed as a percentage  of
total revenues,  SG&A expenses  decreased from 16.7% for the year ended December
31,  1997,  to 14.2% for the year ended  December  31,  1998.  This  decrease is
primarily  reflective  of a reduction in cash  compensation  resulting  from the
integration of the Company's and merged firms' operations, particularly PHB.

      In the year ended December 31, 1998, there were no expenses related to the
liquidation  of a  subsidiary,  compared to  approximately  $328,000 in expenses
related to the liquidation of a subsidiary in the year ended December 31, 1997.

     Merger related and other nonrecurring costs for the year ended December 31,
1998,  increased by $8.1  million to $9.4 million as compared to the  comparable
period of the prior year.  The majority of the merger  related costs in the year
ended December 31, 1998, were associated with the merger of PHB and exiting from
the Company's  financial  advisory  services  business,  as well as the business
combinations with TB&A, IGA, Apogee, FPI, TFC and Estudio Q.

      Stock and stock option  compensation for the year ended December 31, 1998,
decreased  by $7.4  million  from the year  ended  December  31,  1997,  to $2.6
million.  Substantially  all of these costs in both  periods  related to PHB and
include  non-cash,  non-tax  deductible  compensation  based  on the  difference
between  the fair  market and book  values of PHB common  stock  issuable  under
subscriptions within one year of the companies' merger.

      Other income (expenses),  net includes interest income,  interest expense,
minority interest, and other income and expenses.  Other income (expenses),  net
increased by approximately  $670,000 to approximately $270,000 in the year ended
December  31,  1998.  The  primary  reasons  for  this  increase  was a gain  of
approximately  $282,000  from  the  sale  of  certain  assets  of the  Company's
environmental  consulting  business,  as well as a decrease in interest  expense
from the year ended  December 31, 1997,  due to the use of IPO proceeds to repay
the Company's outstanding debt.

      Loss from joint venture for the fiscal year ending  December 31, 1998, was
approximately ($460,000), or (0.2%) expressed as a percentage of total revenues.
The joint  venture,  Cap  Gemini  Hagler  Bailly  LLC,  was  created  to deliver
information  technology  consulting services and solutions to electric,  gas and
water  utilities  and service  providers  in the U.S.  and  Canada.  The Company
expects the joint  venture to turn  profitable  sometime late in the fiscal year
ending December 31, 1999.

      The Company's effective tax rate for the year ended December 31, 1998, was
50.4%.  The 1998  provision for tax is higher than the  provisional  tax rate of
39.7% as a result of the  non-deductibility  for tax  reporting  purposes of the
compensation  charge in connection with subscriptions for the issuance of common
stock, and certain non-deductible merger related costs.

     Net income before extraordinary gains for the year ended December 31, 1998,
increased by  approximately  $10.9  million,  to $6.7 million,  as a result of a
combination of reasons discussed above.

      For the year ended December 31, 1998, there were no  extraordinary  gains,
compared to approximately $2.3 million in extraordinary gains, net of income tax
expense, for the year ended December 31, 1997. The gains in 1997 were the result
of extinguishment of debt at beneficial terms to the Company.

     Net income for the year ended December 31, 1998 increased by  approximately
$8.6 million, to $6.7 million, as a result of the reasons discussed above.

1997 Compared to 1996

      Revenues for the year ended December 31, 1997, increased by $17.5 million,
or 12.2%,  to $160.6  million from the year ended  December  31,  1996.  Of this
increase, $16.2 million is attributable to consulting revenues, and $1.3 million
is attributable to other revenues.  Consulting  revenues  increased by 11.3% for
the year ended  December 31, 1997, as compared to the  comparable  period of the
prior year. A significant  cause of this  increase was the increased  demand for
management   consulting   services   associated  with  the   restructuring   and
deregulation  of the electric  and gas sectors  outside the United  States.  The
overall  increase  was  constrained  by  declining  revenues  generated  from  a
litigation  case  which  represented  approximately  7% of the  Company's  total
revenues  in 1996 and  approximately  1% in 1997  and the  ending  of two  major
private sector  engagements  during the year.  Management  strategy of deploying
core-consulting staff to create and initiate sales of information-based products
and services also mitigated this growth. Other revenues increased 298.2% for the
year ended December 31, 1997, as compared to the comparable  period of the prior
year.  The increase in other revenues was the result of an increase in financial
advisory  services,  as well as the  start  of the  Company's  information-based
products and services business.

      Cost of services for the year ended December 31, 1997,  increased by $10.1
million,  or 9.1%, to $120.6 million from the year ended December 31, 1996. Cost
of services as a percentage  of revenue  decreased  from 77.2% in the year ended
December 31, 1996, to 75.1% in the year ended  December 31, 1997.  The increased
cost was primarily due to an increase from institutional  clients, and the lower
percentage to sales was due to continued  focus on higher margin  private sector
revenues.

       SG&A for the year ended  December  31, 1997,  increased by  approximately
$820,000,  or 3.2%,  to $26.9  million  from the year ended  December  31, 1996.
Expressed as a percentage of total revenues,  SG&A expenses decreased from 18.2%
in the year ended  December  31, 1996,  to 16.7% in the year ended  December 31,
1997,  primarily  due to less  marketing  expenses  relating  to private  sector
revenue  generation as compared to the comparable period in the prior year. SG&A
expenses for the year ended  December 31,  1996,  were  increased as the Company
focused on its marketing  efforts to replace multiyear  institutional  contracts
which were ending during the year.

       Expenses  related  to  the  liquidation  of  a  subsidiary  decreased  by
approximately  $334,000 in the year ended December 31, 1997, from the comparable
period in the prior year.

     Merger related and other nonrecurring costs for the year ended December 31,
1997 were $1.2 million. There were no merger and related and other non-recurring
costs in the  comparable  period of the prior year.  The  majority of the merger
related  costs in the year ended  December 31, 1997,  were  associated  with the
mergers with Apogee and TB&A.

         Stock and stock  option  compensation  for the year ended  December 31,
1997, increased by approximately $3.8 million,  from the year ended December 31,
1996, to approximately  $10.0 million.  Substantially  all of these costs in the
year ended December 31, 1997 were related to PHB and include  non-cash,  non-tax
deductible compensation based on the difference between the fair market and book
values of PHB common stock issuable under  subscriptions  within one year of the
companies' merger.  During the year ended December 31, 1996, the Company amended
its stock plan to change the exercise  price of future  options to be granted to
the  market  value of the  common  stock,  as  opposed to its book value plus an
adjustment for accretion.  All of the costs in the year ended December 31, 1996,
represent the aggregate  difference  between the exercise  price of  outstanding
options,  and the issuance price of common stock sold to employees  during 1996,
and the appraised market value of the common stock on December 31, 1997.

      Other  income  (expenses),  net  increased  by  approximately  $450,000 to
approximately  ($400,000) in the year ended December 31, 1997,  primarily due to
interest  income  earned from the  investment  of IPO funds and a  reduction  in
interest expense  resulting from use of IPO proceeds to pay off outstanding debt
in 1997.

      The Company's effective tax rate for the year ended December 31, 1997, was
442.5%.  The 1997 provision for tax is higher than the  provisional  tax rate of
40% as a result  of the  non-deductibility  for tax  reporting  purposes  of the
compensation  charge in connection with subscriptions for the issuance of common
stock.

     Net loss before  extraordinary  gains for the year ended December 31, 1997,
decreased by approximately $1.3 million,  to ($4.2) million,  as a result of the
reasons discussed above.

      Extraordinary  gains for the year ended  December 31,  1997,  increased by
approximately $2.2 million,  to approximately $2.3 million,  from the year ended
December 31, 1996. These gains were the result of the  extinguishment of debt at
beneficial terms to the Company.

     Net loss for the year ended December 31, 1997,  increased by  approximately
$840,000,  to ($1.9)  million,  from the year ended  December 31, 1996,  for the
reasons discussed above.

Liquidity and Capital Resources

      As of December 31, 1998,  working capital was $54.3 million as compared to
$34.1  million at December  31,  1997.  The  increase  was  primarily  due to an
increase  in cash from the sale of the  Company's  investments,  an  increase in
accounts receivable, and a decrease in accrued compensation and benefits.

     Net cash of approximately  $341,000 was used in operating activities during
the year ended December 31, 1998. Cash provided by net income,  depreciation and
amortization,  deferred  income taxes,  and stock and stock option  compensation
were  offset by a  significant  increase in  accounts  receivable,  as well as a
decrease in accrued  compensation  and benefits for the year ended  December 31,
1998.

      Investment activities provided $1.6 million during the year ended December
31, 1998. The sale of investments for approximately  $6.5 million,  and proceeds
from the  disposition  of certain  public sector assets for  approximately  $2.9
million  were  largely  offset by the  investment  of $4.0 million in office and
computer  related  equipment,   leasehold  improvements,   and  other  resources
necessary  for the  growth  of the  Company,  as well  as $3.3  million  used to
purchase the assets of TFC and the stock of FPI, the stock of Estudio Q, and the
balance  of the  Company's  interest  in a  previously  majority  owned  foreign
subsidiary.

      Financing activities provided $9.7 million for the year ended December 31,
1998.  Cash provided by the issuance of 470,975  shares of the Company's  common
stock  for  consideration,  net of  proceeds,  of $11.8  million  to Cap  Gemini
America,  Inc.,  and  approximately  $900,000  from other stock  issuance,  were
partially  offset by payments on net  borrowings on the Company's line of credit
and  principal  payments on debt of  approximately  $1.5  million and  $300,000,
respectively,  and a payment of  approximately  $1.0 million for the purchase of
common stock from a dissenting shareholder resulting from a business combination
during 1998.  Net proceeds  from equity  financing  are invested in  short-term,
interest-bearing investment grade securities.

     The Company's  primary  source of liquidity for the past 12 months has been
cash flows from sales of common stock,  periodically  supplemented by borrowings
under a bank line of credit.  During  the year  ended  December  31,  1998,  the
Company established $50 million in revolving credit facilities with NationsBank.
The balance  available  under the line of credit at December 31, 1998, was $50.0
million.  The Company  believes that current  projected levels of cash flows and
the availability of financing,  including  borrowings under the Company's credit
facility, will be adequate to fund its anticipated cash needs, which may include
future  acquisitions  of  complementary  businesses,  for the next 12 months and
foreseeable  future. The Company,  depending on market conditions,  may consider
other sources of financing, including equity financing.

New Accounting Pronouncements

     In June 1997, the FASB issued Statement No. 130,  "Reporting  Comprehensive
Income" which  established  standards for reporting and display of comprehensive
income and its components (revenues,  expenses,  gains and losses) in a full set
of  general-purpose  financial  statements.  This  statement  requires  that  an
enterprise  classify  items of other  comprehensive  income by their nature in a
financial  statement and display the accumulated  balance of other comprehensive
income separately from retained  earnings and additional  paid-in capital in the
equity  section of the balance  sheet.  This  statement is effective  for fiscal
years  beginning after December 15, 1997. The Company has adopted the effects of
this statement effecive January 1, 1998.

      In June  1997,  the FASB  issued  Statement  No.  131,  "Disclosure  about
Segments of an Enterprise and Related  Information" which established  standards
for public business  enterprises to report  information about operating segments
in annual financial statements and requires those enterprises to report selected
information about operating segments.  The financial  information is required to
be  reported  on the basis that it is used  internally  for  evaluating  segment
performance  and  deciding  how to allocate  resources  to  segments.  Operating
segments  are  components  of  an  enterprise  about  which  separate  financial
information  is  available  that is evaluated  regularly by the chief  operating
decision  maker  in  deciding  how  to  allocate   resources  and  in  assessing
performance.  This  statement is effective for financial  statements for periods
beginning  after  December 15, 1997.  The Company  operates in  principally  one
business segment and,  accordingly,  no additional  disclosures are necessary to
comply with this statement.

     In June 1998, the Financial  Accounting Standards Board issued Statement on
Financial  Accounting  Standards No. 133 (SFAS 133),  "Accounting for Derivative
Instruments and Hedging  Activities."  SFAS 133  standardizes the accounting for
derivative  instruments  by requiring  that an entity  recognize  derivatives as
assets or liabilities in the statement of financial position and measure them at
fair value.  This  Statement is  effective  for all quarters of all fiscal years
beginning  after June 15, 1999. This Statement is not expected to ahve an impact
on the Company's consolidated financial statements.

Year 2000

         The Year 2000 issue is the result of  computer  hardware  and  software
being  designed  with the year field  being set for two  digits  instead of four
digits.  Computer  programs  and  systems  with this  problem  will be unable to
properly  distinguish  between the year 2000 and the year 1900. As a result, the
programs could fail or yield incorrect results. The Company's business,  as well
of those of its principal  suppliers and clients, is dependent on the ability of
its software and hardware systems to properly  function.  Failure of one or more
of these systems of the Company or a material  client or supplier  could disrupt
the Company's  operations  and cause a material  adverse impact on the Company's
business, results of operations and financial condition.

The Company's Year 2000 Strategy

     The Company has  established  the Year 2000  Readiness Plan (the "Plan") to
prepare  for the Year  2000  issue.  This  Plan is  comprised  of the  following
elements:

     1. Audit, remediation, and testing of internal systems.

     2.  Obtaining  assurance or information on the state of Year 2000 readiness
of our material  clients and suppliers who exchange  information  electronically
with us or upon whom our work product may depend.

     3. Developing contingency plans, when practical,  to address potential Year
2000 failures.

         The  Company's  goal  is to  complete  implementation  of the  Plan  by
September 30, 1999.

Detailed  below are the status of progress and timetables for each of the phases
of the Plan.

         The  Company  made  several   acquisitions  in  1998.  It  undertook  a
comprehensive  due  diligence  examination  that  identified  general  Year 2000
Readiness issues for itself and the companies it acquired.  The Company recently
formalized  its  efforts by  establishing  a Year 2000  Working  Committee  (the
"Committee") led by its Chief Information  Officer to oversee the integration of
its Year 2000 efforts and to implement the Plan. The Committee includes the COO,
CFO, General Counsel,  and other Company  executives and outside  consultants as
required. The Company has engaged a consultant to complete the assessment of its
domestic  offices  and to assist in the  assessment  of its major  international
offices.

         The Company's  front office  systems (used for the delivery of services
to clients), both hardware and software, were replaced or significantly upgraded
in 1997 and 1998  and were  manufactured  to be Year  2000  ready  (with  minor,
vendor-identified  problems).  The Company currently expects that the process of
updating those systems that are not Year 2000 ready will be completed by the end
of the second quarter of 1999.

         The Company does not employ any significant  custom  programming in its
front office, work product,  or back office systems.  The Company's work product
is  generated  almost  exclusively  with  commercially   available  statistical,
econometric,  word processing,  spreadsheet,  database, or mathematical software
for  which the  Company  has  obtained  Year 2000  Readiness  assurances.  These
software products have been audited and updated where appropriate.

         The Company will implement a firm wide software  application to monitor
Year 2000 compliance of new work product and to provide a testing  mechanism for
the  re-use  of  models,  spreadsheets,  or  databases.  This  application  is a
commercially  available  Year 2000 audit and  remediation  product  specifically
designed for Microsoft Windows compliant software applications.

         A  conversion  was  undertaken  in 1998 to  replace a  significant  and
non-compliant analytic system (used to service client analysis needs), including
hardware and software,  with a compliant system.  The implementation is complete
and the  conversion  of  existing  analytic  applications  will be  complete  by
September 30, 1999.

         Back office systems including financial accounting, project accounting,
fixed asset management,  human resources,  payroll, and conflict management have
been  replaced,  updated with vendor  supplied Year 2000 fixes,  or converted to
compliant versions of the software.  During the second quarter 1999, the Company
plans to  undertake a  comprehensive  test of its back office  systems.  Certain
models of personal  computers have been identified as non-compliant  and will be
replaced  in 1999.  The  number of Year 2000  replacements  will not  exceed the
normal annual personal computer turnover.

         The Company is contacting  the vendors of its principal  office systems
in order to obtain proof of Year 2000 readiness.  The Company's  material office
systems include its telephone, communications and networking equipment, security
and facilities systems,  copiers, pagers, voicemail, and faxing systems. Because
the  Company is highly  decentralized  with over 22 domestic  and  international
offices, it does not expect the audit and remediation of these office systems to
be complete  before  September  30, 1999.  Some office  systems in the Company's
international  offices  will not be  corrected  by December  31,  1999,  but the
Company does not expect such systems to materially  affect the Company's ability
to complete its engagements.

Clients

         The Company's  clients include  domestic and  international  companies,
private law firms,  the United States and state,  local and foreign  governments
and  governmental  agencies and  government-owned  enterprises.  The Company has
responded to Year 2000 compliance  surveys from over 50 of its major clients and
shared the  readiness  information  disclosed  here.  The Company is planning to
survey in the second quarter its top 25 clients  (measured by revenue  generated
for the Company in 1998) to  determine  their Year 2000  readiness.  The Company
plans to survey other clients if circumstances warrant and to survey new clients
upon new engagements.





Material Vendors

         The Company performs analytic work on time sensitive  matters.  Certain
vendors have been identified as critical to implementing the Plan. These vendors
include payroll,  credit,  transportation,  information  resources,  and certain
maintenance  providers of mission critical hardware and software. If one or more
of the Company's principal vendors experiences  significant  business disruption
as a result of the Year 2000 issue,  it could have a material  adverse effect on
the Company's  business,  results of operations  and  financial  condition.  For
example, if the Company's principal suppliers of real-time  electricity data are
not functioning properly, the Company may be unable to perform analytic work for
clients.  Similarly,  if hardware used to perform  modeling  cannot be supported
because of a Year 2000 issue at the vendor, the Company's ability to meet client
demands for time sensitive analysis might be jeopardized.  The Committee will be
contacting  the Company's  principal  vendors during the second quarter of 1999.
Based on the responses,  the Committee may need to develop  contingency plans to
replace those vendors whose ability to certify Year 2000  readiness is in doubt.
The Committee  expects that the process of  evaluating  and working with outside
vendors will continue into the third quarter of 1999.

Contingency Planning

         The Committee is  developing a  contingency  plan in the event that any
material system or vendor will not be Year 2000 ready by December 31, 1999. This
contingency  plan is  scheduled to be  substantially  complete by the end of the
third  quarter of 1999,  although it will be reviewed and refined  thereafter as
the Committee continues to evaluate the Company's systems and vendors.

Costs

         The Company will budget  $300,000 in each of the next two fiscal years,
1999 and 2000, to cover the costs of  evaluating  systems,  acquiring  Year 2000
remediation  software,  additional  testing of hardware and software,  hiring an
outside  Year  2000  consultant,   and  administrative   costs  associated  with
implementing  the Plan.  Although  the  Company  believes  this  amount  will be
sufficient to meet the costs of the Company's Year 2000 readiness efforts, there
can be no assurance that the costs to implement the Plan will not  significantly
exceed the Company's  current  estimates.  To date,  expenditures  for Year 2000
readiness  have been nominal and  associated  with the rapid  implementation  of
already planned front office and back office systems upgrades.

Risks

         At present,  the Company  perceives that its greatest Year 2000 risk is
its dependence on an external  network of information  providers,  vendors,  and
experts to complete its engagements. Even if the Company can satisfy itself that
the systems of its material  suppliers  and partners are Year 2000 ready,  those
suppliers  and partners in turn rely on a myriad of  suppliers to operate  their
businesses.  Year  2000-related  failures  far removed  from the  Company  could
trigger a chain of events that could  materially  harm the  Company's  business.
Certain clients, despite their best efforts, may suffer the effects of Year 2000
failures  of others  and thus  delay,  cancel,  or  substantially  alter work in
progress  resulting  in a  negative  effect on the  operations  of the  Company,
including  the  failure  to  meet  financial  expectations  or the  loss  of key
personnel.  Such a chain of events  could also lead to  litigation  against  the
Company.  There can be no  assurance  that Year  2000  problems  will not have a
material  adverse effect on the Company's  business,  results of operations,  or
financial condition.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

      The  following  discussion  about the  Company's  market risk  disclosures
involves forward-looking statements. Actual results could differ materially. The
Company is exposed to market  risk from  changes in  interest  rates and foreign
exchange rates.  Adverse  changes in either  interest rates or foreign  exchange
rates can have a material effect on the Company's operations.

      Interest  Rate  Risk:  The  Company  is  subject  to risk from  changes in
interest rates. The Company utilizes U.S. dollar denominated  borrowings to fund
its operational  needs, and as of December 31, 1998, had total  outstanding debt
of approximately $1,000,000. A hypothetical 10% adverse change in interest rates
on the Company's total  outstanding  debt as of December 31, 1998 would not have
been material. Interest rates may move in the Company's favor. While the Company
does not expect to incur material losses as a result of this interest rate risk,
there can be no assurance that losses will not result.

      Foreign  Currency  Exchange  Risk:  The  Company  is  subject to risk from
changes  in  foreign  exchange  rates for its  subsidiaries  which use a foreign
currency as their functional currency and are translated into U.S. dollars. Such
changes could result in cumulative translation gains or losses that are included
in shareholders' equity.

      In the year ended December 31, 1998,  approximately 10.8% of the Company's
total  revenues  were derived from  operations  in foreign  countries  including
Argentina,  Armenia, Australia, Canada, France, Ireland, Indonesia, Pakistan and
New  Zealand.  Exchange  rate  fluctuations  between  the  U.S.  dollar  and the
currencies of these countries result in positive or negative fluctuations in the
amounts relating to foreign  operations  reported in the Company's  consolidated
financial  statements.  None  of  the  components  of  the  Company's  financial
statements were materially  affected by exchange rate  fluctuations in the years
ended December 31, 1996, 1997, or 1998.

      The potential loss resulting from a hypothetical uniform 10% strengthening
in the value of the U.S. dollar relative to the foreign currencies in which some
of the  Company's  sales are  denominated  would have  resulted in a decrease in
earnings  of   approximately   $390,000.   The  potential  impact  of  the  same
hypothetical uniform change on the Company's cash flows would have resulted in a
decrease in cash flows of approximately  $180,000. This calculation assumes that
each  exchange  rate would  change in the same  direction  relative  to the U.S.
dollar. Foreign exchange rates may move in the Company's favor.

      The  sensitivity  of earnings and cash flows to  fluctuations  in exchange
rates is periodically assessed by management by applying an appropriate range of
potential rate fluctuations to the Company's assets, liabilities,  and projected
results of operations denominated in foreign currency. Historically, the Company
has not used foreign currency options and forward contracts to hedge against the
earnings  effects of such  fluctuations.  While the  Company  does not expect to
incur  material  losses  as a result  of this  currency  risk,  there  can be no
assurance that losses will not result.

                         Report of Independent Auditors

Board of Directors and Stockholders
Hagler Bailly, Inc.

We have audited the accompanying  consolidated  balance sheets of Hagler Bailly,
Inc. as of December 31, 1997 and 1998, and the related  consolidated  statements
of operations,  stockholders' equity, and cash flows for each of the three years
in the period ended  December  31,  1998.  These  financial  statements  are the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these financial statements based on our audits.

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

In our opinion, the consolidated  financial statements referred to above present
fairly, in all material respects,  the consolidated financial position of Hagler
Bailly,  Inc. at December 31, 1997 and 1998,  and the results of its  operations
and its cash flows for each of the three years in the period ended  December 31,
1998 in conformity with generally accepted accounting principles.

                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
                      (in thousands except per share data)


1.    Organization

     Hagler  Bailly,  Inc.  ("Hagler  Bailly" or the  "Company")  is a worldwide
provider of management consulting and other advisory services to the private and
public sectors.  The Company operates in principally one business  segment.  The
Company is  headquartered  in Arlington,  Virginia and has offices in the United
States, Asia, Europe, and Latin America.

     Hagler  Bailly was  organized  under the laws of the state of Delaware  and
formed for the primary  purpose of  facilitating  the  acquisition of RCG/Hagler
Bailly,  Inc.   ("Predecessor")  by  its  management.   The  Predecessor  was  a
wholly-owned  subsidiary  of  RCG  International,  Inc.  ("RCG").  The  date  of
inception of the Company was May 5, 1995. The Company had no operations from May
5, 1995 to May 25, 1995. Effective on the close of business on May 25, 1995, the
Company, through a wholly-owned subsidiary,  acquired all of the voting stock of
the Predecessor and the Company began operations on May 26, 1995.

     On July 3, 1997,  the Company  consummated  an initial  public  offering of
2,500,000  shares at an offering price of $14 per share. The offering netted the
Company $30.3 million used to pay off debt then outstanding,  fund acquisitions,
and provide working capital needs.

2.    Summary of Significant Accounting Policies

Principles of Consolidation

      The consolidated  financial statements include the accounts of the Company
and its wholly-owned  subsidiaries.  All significant  intercompany  accounts and
transactions have been eliminated in consolidation.

      In 1997,  the Company  acquired a 7.8%  minority  ownership  interest in a
consulting  business  in  the  United  Kingdom  for  cash  of  $531.  Due to the
uncertainty of recovery,  the Company has established a valuation  allowance for
this  investment.  During 1997 and 1998, the Company  provided  services to, and
purchased  consulting services from, this consulting business of $38, $288, $405
and $2,  respectively.  At December 31, 1997 and 1998,  the accounts  receivable
from this consulting business amounted to $135 and $543, respectively.

Foreign Currency Translation

         The assets and liabilities of the Company's  foreign  subsidiaries  are
translated  into U.S.  dollars using  exchange rates at the balance sheet dates.
Income  and  expense  items are  translated  at average  exchange  rates for the
respective periods. The effect of translating these amounts at

<PAGE>


     different  rates is  included  as a component  of  comprehensive  income in
stockholders' equity.  Transaction gains and losses are charged to operations in
the period in which they occur.  Transaction  gain  (losses)  in 1996,  1997 and
1998, amounted to $240, ($373) and $420, respectively.

Use of Estimates

      The  preparation of consolidated  financial  statements in conformity with
generally accepted  accounting  principles requires management to make estimates
and assumptions that affect the amounts  reported in the consolidated  financial
statements and  accompanying  notes,  in  particular,  estimates of revenues and
contract costs used in the earnings  recognition  process.  Actual results could
differ from those estimates.

Cash and Cash Equivalents

      Cash equivalents are short-term, highly liquid investments,  which have an
original  maturity  when acquired of three months or less. At December 31, 1998,
cash equivalents include $6,810 in money market funds.

Marketable Securities

      Marketable  securities  are  classified  as  available-for-sale   and  are
recorded at fair market value with  unrealized  gains and losses,  net of taxes,
reported as a component of  comprehensive  income in  stockholders'  equity,  if
material.

      Realized  gains,  losses and  declines in market  value judged to be other
than  temporary  are included in investment  income.  Interest and dividends are
included in investment income (see Note 5).

Property and Equipment

      Property and equipment are recorded at original cost and depreciated using
a combination of  straight-line  and  accelerated  methods over their  estimated
useful lives of three to ten years.  Leasehold improvements are recorded at cost
and amortized  over the shorter of their useful lives or the term of the related
leases by use of the straight-line method.

Revenue Recognition

      Consulting  revenue  represents revenue generated by professional staff of
the Company, and also includes subcontractor revenue that is principally related
to services  provided by  subcontractors  and independent  consultants which are
billed by the Company to its clients.  Other revenue includes those derived from
information-based  products  and  services,  financial  advisory  services,  and
publication services.

      Revenue from  cost-plus  fixed-fee  contracts is  recognized  as costs are
incurred on the basis of direct costs plus  allowable  indirect  costs and a pro
rata portion of estimated fee.

      Revenue   from   fixed-bid   type   contracts   is   recognized   on   the
percentage-of-completion  method of accounting with costs and estimated  profits
included in revenue based on the relationship  that contract costs incurred bear
to management's  estimate of total contract costs.  Losses,  if any, are accrued
when they become known and the amount of the loss is reasonably determinable.

      Revenue from time and materials  contracts is recognized in the period the
work is performed.  Estimated  losses, if any, are provided for at the time such
losses become known.

      Revenue  from  standard  daily rate  contracts  is  recognized  at amounts
represented  by the  agreed-upon  billing  amounts and costs are  recognized  as
incurred.  Estimated  losses,  if any,  are provided for at the time such losses
become known.

      Amounts  billed or received in excess of revenue  recognized in accordance
with the  Company's  revenue  recognition  policy are  classified as billings in
excess of cost in the accompanying balance sheets.


Income Taxes

      The Company  provides for income taxes in  accordance  with the  liability
method.  Under this method,  deferred tax assets and  liabilities are determined
based on temporary  differences  between  financial  and tax bases of assets and
liabilities  and are measured  using the enacted tax rates and laws that will be
in effect when the differences are expected to reverse.


Fair Value of Financial Instruments

         The Company  considers the recorded  value of its financial  assets and
liabilities,  which  consist  primarily of cash and cash  equivalents,  accounts
receivable,  accounts payable,  and accrued compensation to approximate the fair
value of the respective assets and liabilities at December 31, 1997 and 1998.


Intangibles

      The purchase price of acquisitions is allocated to the assets acquired and
the liabilities assumed based upon their fair values as of the acquisition date.
The excess of the purchase  price over the fair value of assets  acquired in the
purchase is recorded as intangible assets,  including goodwill, and is amortized
over 5 to 25 years on a straight-line  basis.  Intangible assets at December 31,
1997  and  1998  are net of  accumulated  amortization  of  $1,753  and  $2,441,
respectively.  Amortization  expense for the years ended December 31, 1996, 1997
and 1998, was $683, $736 and $688, respectively.


Statement of Financial Accounting Standards No. 121

      The  Company  assesses  the  impairment  of  long-lived  assets  including
intangible assets in accordance with 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 requires impairment losses to be
recognized for long-lived  assets when  indicators of impairment are present and
the  undiscounted  cash flows are not sufficient to recover the assets' carrying
amount.  Intangibles  are also  evaluated for  recoverability  by estimating the
projected  undiscounted cash flows,  excluding interest, of the related business
activities. The impairment loss of these assets, including goodwill, is measured
by comparing the carrying  amount of the asset to its fair value with any excess
of carrying  value over fair value  written  off.  Fair value is based on market
prices where  available,  an estimate of market value,  or determined by various
valuation techniques including discounted cash flow.

Merger Related and other Nonrecurring Costs

     For the years ended December 31, 1996,  1997, and 1998,  merger related and
other nonrecurring costs were approximately $0, $1,235 and $9,382, respectively.
Cost of effecting  mergers and  subsequently  integrating  the operations of the
various merged  companies are recorded as merger related and other  nonrecurring
costs when incurred.  These costs consist  primarily of direct merger costs such
as investment  banking,  legal,  accounting  and filing fees, as well as related
costs incurred to realign corporate,  administrative,  and personnel  functions,
implement  efficiencies with regard to information  systems and offices,  change
the corporate identity for the acquired  companies,  and other expenses incurred
to integrate  operations.  Also included  were  nonrecurring  charges  including
certain  asset  impairments  relating  to software  development  costs and notes
receivable,  and the disposition of other investment assets as discussed in Note
18.

Reclassification

     Certain  amounts  in the  prior  period's  financial  statements  have been
reclassified to conform to the 1998 presentation.

New Accounting Pronouncements

     In June 1997, the FASB issued Statement No. 130,  "Reporting  Comprehensive
Income" which  established  standards for reporting and display of comprehensive
income and its components (revenues,  expenses,  gains and losses) in a full set
of  general-purpose  financial  statements.  This  statement  requires  that  an
enterprise  classify  items of other  comprehensive  income by their nature in a
financial  statement and display the accumulated  balance of other comprehensive
income separately from retained  earnings and additional  paid-in capital in the
equity  section of the balance  sheet.  This  statement is effective  for fiscal
years  beginning after December 15, 1997. The Company has adopted the effects of
this statement effective January 1, 1998.

     In June 1997, the FASB issued Statement No. 131, "Disclosure about Segments
of an Enterprise and Related Information" which established standards for public
business  enterprises to report  information about operating  segments in annual
financial   statements  and  requires  those   enterprises  to  report  selected
information about operating segments.  The financial  information is required to
be  reported  on the basis that it is used  internally  for  evaluating  segment
performance  and  deciding  how to allocate  resources  to  segments.  Operating
segments  are  components  of  an  enterprise  about  which  separate  financial
information  is  available  that is evaluated  regularly by the chief  operating
decision  maker  in  deciding  how  to  allocate   resources  and  in  assessing
performance.  This  statement is effective for financial  statements for periods
beginning  after  December 15, 1997.  The Company  operates in  principally  one
business segment and,  accordingly,  no additional  disclosures are necessary to
comply with this statement.

     In June 1998, the Financial  Accounting Standards Board issued Statement on
Financial  Accounting  Standards No. 133 (SFAS 133),  "Accounting for Derivative
Instruments and Hedging  Activities."  SFAS 133  standardizes the accounting for
derivative  instruments  by requiring  that an entity  recognize  derivatives as
assets or liabilities in the statement of financial position and measure them at
fair value.  This  Statement is  effective  for all quarters of all fiscal years
beginning  after June 15, 1999. This Statement is not expected to have an impact
on the Company's consolidated financial statements.

3.    Business Combinations and Joint Ventures

     On December 1, 1997,  the Company  exchanged  409,985  shares of its common

Company has committed to provide $1,000 cash under the joint venture  agreements
of which approximately $500 cash and approximately $200 in software  development
costs were  provided  during the year  ended  December  31,  1998.  The  Company
accounts for its investment under the equity method and, accordingly, recognized
a loss on equity investment of $463 for the year ended December 31, 1998.

4.    Earnings Per Share

     In 1997, the Financial Accounting Standards Board issued Statement No. 128,
"Earnings  per Share"  ("Statement  No.  128").  Statement  No. 128 replaced the
calculation  of  primary  and fully  diluted  earnings  per share with basic and
diluted earnings per share.  Unlike primary  earnings per share,  basic earnings
per share  excludes any dilutive  effects of options,  warrants and  convertible
securities.  Diluted  earnings  per  share  is very  similar  to the  previously
reported  fully diluted  earnings per share.  All earnings per share amounts for
all periods have been presented,  and where appropriate,  restated to conform to
the Statement No. 128 requirements.

     The  following  table  sets  forth the  computation  of basic  and  diluted
earnings per share:

                                                 -------------------------------
         Billed amounts                             $42,911             $38,914

         Allowance for possible losses              (3,873)             (3,888)
                                                  ------------------------------
         Total                                      $51,857             $59,092
                                                 ===============================


      The activity in the allowance for possible losses for years ended December
31 is as follows:

                                                       1997                 1998
                                                   -----------------------------
         Balance at beginning of year                $2,901               $3,873
         Provision for losses charged to expense      2,395                1,135

                                                   =============================


     All billed and  unbilled  receivable  amounts are  expected to be collected
during the next fiscal year.  Management  has provided an allowance  for amounts
that it  believes  are  doubtful  based on an  analysis  of  estimated  ultimate
realization.  Substantially  all the retention  relates to contracts for which a
final invoice is submitted upon  completion of indirect cost audits and contract
close-outs; therefore, it is anticipated that the retention amounts will not all
be collected within the next fiscal year.



7.    Property and Equipment

         Components of property and equipment at December 31 are as follows:



                                                      1997             1998
                                                  ------------------------------
        Office equipment and furniture               $14,212          $17,100
        Leasehold improvements                         2,364            3,189
                                                  ------------------------------
                                                      16,576           20,289
        Accumulated depreciation and amortization    (11,063)         (13,826)
                                                   -----------------------------
                                                      $5,513           $6,463
                                                   =============================


     Depreciation  and  amortization  expense on property and  equipment for the
years ended December 31, 1996, 1997 and 1998, was approximately  $1,677,  $2,123
and $3,121,  respectively.  Costs of repairs  and  maintenance  of property  and
equipment are charged to expense as incurred.

8.    Software Development Costs

     At  December  31,  1997  and  1998,  the  Company  had  $2,463  and $898 of
capitalized  software  development  costs  net of $49 and  $560  of  accumulated
amortization,  respectively.  Amortization  expense for the years ended December
31, 1996, 1997 and 1998 was  approximately $0, $49 and $511,  respectively.  The
Company  accounts for these software  development  costs in accordance with FASB
86,  "Accounting  for the Costs of  Computer  Software  to Be Sold,  Leased,  or
Otherwise Marketed".

     Capitalized  software  development  costs are  amortized  on a  product  by
product  basis  starting  when the product is available  for general  release to
customers.  Amortization is calculated using the  straight-line  method over the
remaining  estimated  economic  life of the  product.  The Company  periodically
evaluates the net realizable value of all unamortized  capitalized costs. During
1998,  management  determined that certain software development costs were fully
impaired due to the  duplication  of  technologies  resulting from the Company's
1998 mergers and the Cap Gemini Hagler Bailly L.L.C. joint venture.  As a result
of such impairment,  the Company expensed approximately $1,107 as merger related
and other nonrecurring costs (see Note 18).

9.    Note Receivable

      During 1997,  the Company  entered into a bridge loan agreement for $1,000
with another company. The loan was due in six equal installments  beginning June
1, 1998.  The loan accrued  interest at 15% and was secured by all of the assets
of the borrower. The loan agreement allowed the Company to purchase an ownership
interest of this company as defined in the loan agreement.

     During  1998,  the  borrower  defaulted  on its  obligation  under the note
receivable.  Management has determined  that the loan is  uncollectable  and has
written off the entire amount of the original loan as other  nonrecurring  costs
(see Note 18).

10.   Bank Line of Credit

      At December 31, 1997, the Company had a line of credit  arrangement with a
bank which provided funds up to $15,000  subject to sufficient  collateral.  The
line was secured  primarily by the Company's  accounts  receivable  and contract
rights.  Under the terms of the line of credit,  interest was payable monthly at
the  bank's  prime  rate  with an annual  fee  equal to 1/4 of 1% of the  unused
portion of the available line of credit. The line of credit agreement  contained
certain  covenants which,  among other things,  restricted future borrowings and
required the Company to maintain certain financial ratios. At December 31, 1997,
the  Company  had  available  borrowing  capacity  of $15,000  under the line of
credit.

     At December  31,  1997,  PHB had a line of credit  arrangement  with a bank
which enabled PHB to borrow up to $4,000 subject to certain  restrictions  which
limited  the  borrowing  base as defined in the  respective  lending  agreement.
Interest was payable at the bank's base rate or the Federal Funds effective rate
plus 0.5%,  and required a commitment fee of 0.5% on the average daily amount of
the  unborrowed  portion of the  commitment,  payable  quarterly in arrears.  At
December 31, 1997, PHB had available borrowing capacity of $2,500 under the line
of credit.

     On  November  20,  1998,  the  Company  entered  into a new line of  credit
arrangement  with a bank enabling the Company to borrow up to $50,000 subject to
certain restrictions.  The Company paid all outstanding balances on its previous
lines of credit,  which were terminated upon  commencement of the new agreement.
Under the terms of the new agreement,  interest is payable at the greater of the
bank's  base  rate  or the  Federal  Funds  effective  rate  plus  0.5%,  or the
applicable  London   Inter-Bank   Offered  Rate  ("LIBOR")  plus  an  additional
percentage ranging from 0.8% to 1.75% depending on certain financial ratios. The
agreement also requires a commitment fee of 0.19% plus an additional  percentage
ranging from 0.01% to 0.06% depending on certain financial ratios,  based on the
average  daily  amount of the  unborrowed  portion  of the  commitment,  payable
quarterly in arrears.  The line of credit matures on November 20, 2001. The line
of credit  agreement  contains  certain  covenants,  which  among  other  things
restrict future borrowings and require the Company to maintain certain financial
ratios.  On December 31, 1998, the Company had available  borrowing  capacity of
$50,000 under the line of credit.



11.    Notes Payable

      During  1997,  the Company  renegotiated  the terms of a note payable to a
financial  institution  resulting in an  extraordinary  gain. As a result of the
1997 renegotiation,  the Company paid the financial institution $360 in cash and
entered into a new note payable of $180,  which was  outstanding at December 31,
1997. The $180 note was paid in full in December 1998.

     At December 31, 1997, TB&A had notes payable to related parties,  primarily
employees and directors, of $620. These notes were paid in full in October 1998.

     At December 31, 1997,  PHB had notes  payable to former  employees of $431.
These notes were paid in full in October 1998.

     The Company has a note payable, related to an acquisition of certain of the
assets and liabilities of The Fieldston  Company,  in the amount of $1,000.  The
payments are due in three annual  installments  beginning in November  1999, and
the note accrues interest equal to the three month LIBOR rate plus 1.5%.

     For the years ended December 31, 1996 and 1997, the Company settled several
notes payable with favorable  terms to the Company,  resulting in  extraordinary
gains of approximately $145 and $2,336, respectively.

     The Company incurred interest under all indebtedness of $1,450,  $1,301 and
$410 for the years ended December 31, 1996, 1997, and 1998, respectively.




12.      Income Taxes

     Prior to the IPO of the  Company's  common  stock in 1997 the  Company  had
historically filed its consolidated federal income tax return on the cash basis,
whereby for tax purposes, revenue was recognized when received and expenses were
recognized when paid. In addition, prior to its merger with the Company, PHB had
also filed its consolidated  federal income tax return on the cash basis.  Under
this basis,  the timing of certain  transactions,  primarily the  collections of
accounts  receivable and the payments of accounts  payable and accrued  expenses
were  applied  to  different  periods  for  financial  statement  and income tax
reporting  purposes.  Deferred  federal and state income taxes were provided for
these  temporary  differences.  Upon  consummation  of the IPO of the  Company's
Common  Stock  during  1997,  the Company was  required to change to the accrual
method for income tax reporting.

     Components of income tax expense consisted of the following:

                              For the years ended December 31,

                          1996              1997             1998

      The Company paid income taxes of $248, $3,117 and $4,995 during 1996, 1997
and 1998, respectively.

13.   Stockholders' Equity

      The Company in May 1995 issued  6,915,067 shares of $.01 par value Class A
common  stock  and  2,074,521  shares of $.01 par  value  Class B common  stock.
Pursuant to a  stockholders'  agreement,  all of the Company's  common stock and
options had certain  restrictions  on ownership and were subject to a repurchase
provision.  Class B shares were not  eligible  for  dividends  and had no voting
privileges.

      Under the Company's Employee Incentive and Non-Qualified  Stock Option and
Restricted Stock Plan (the "Stock Option Plan"), the Company may grant qualified
and  non-qualified  stock options to  employees,  consultants  and  non-employee
members of the board of directors to purchase  common  stock.  Prior to December
31,  1996,  the  Company's  Stock  Option Plan was a formula  based plan and was
authorized to grant options to purchase Class A and B shares. The exercise price
of options  granted  were  based upon the book value per share at May 26,  1995,
adjusted  for  accretion of formula  value  during any interim  period up to the
grant date.  Under the Stock  Option  Plan,  options to purchase  Class B shares
granted  did not accrue  value to the  option  holder  until  date of  exercise.
Options to purchase  Class A shares  accrued value to the option holder from the
date of grant.

     The issuance of common stock and  repurchase  of common stock for the years
ended  December  31,  1996,  1997 and 1998 is  primarily  the  result  of equity
transactions at PHB and TB&A.  These  transactions  were made under  established
Company  plans  and in a  manner  consistent  with  historic  patterns  of stock
issuance or repurchase.

      Effective at December  31,  1996,  the Company (a) adopted an amendment to
its Stock Option Plan which changed the exercise  price of future  options to be
granted  thereunder to the fair value of the underlying common stock; and (b) in
connection with a  reclassification  of its common stock amended all outstanding
options  to  purchase  971,963  Class B shares  vesting  on  January  1, 1997 to
substitute  0.9 of a Class A  share  for  each  Class  B share  underlying  such
options.  In addition,  a remaining total of 971,963 options to purchase Class B
shares  vesting on  January  1, 1998 were  canceled.  As a result,  the  Company
recorded  a  non-recurring,  non-cash  charge to  operations  of $6,172 of which
$4,618  was for  options to  purchase  common  stock and $1,554 was for  394,160
shares of common stock sold to employees  during 1996.  These charges  represent
the aggregate  difference between the exercise price of such outstanding options
or the issuance price of common stock sold to employees during 1996, as the case
may be,  and the  appraised  market  value  of the  underlying  common  stock at
December 31, 1996.

      In connection with the merger with the Company,  PHB recognized  non-cash,
non-tax  deductible  compensation  charges as of December 31, 1997 and 1998,  of
$9,885 and $2,595,  respectively.  These amounts reflect the difference  between
the fair value and the book value of shares of common stock issuable  within one
year of the mergers' close.

      Options granted after 1996 vest over periods  ranging from  immediately to
three years and are  exercisable  for five years.  Options  issued prior to 1996
generally vest 50% after eighteen months and fully after an additional year.
Once vested, the options are exercisable for ten years.

      In August of 1998, the Company's shareholders approved an amendment to the
Stock  Option Plan that  increased  the total  number of shares of common  stock
reserved  for  issuance  from  3,200,000  to  5,000,000.  At December  31, 1998,
2,350,542 shares of common stock were available for grant under the Stock Option
Plan.

      Pro forma  information  regarding  net income (loss) and per share data is
required  by SFAS  No.  123,  and has  been  determined  as if the  Company  had
accounted for its stock options  under the fair value method  therein.  The fair
value for options granted from May 25, 1997 to July 9, 1997 was estimated at the
date  of  grant   using  a  minimal   valuation   method   with  the   following
weighted-average  assumptions,  risk free  interest  rate of 5.25%,  no expected
dividends and an average expected life of the options of 4 years.

      For all options issued subsequent to July 9, 1997, in accordance with SFAS
123,  the fair value was  estimated  at the date of grant using a  Black-Scholes
option pricing model with the following  weighted-average  assumptions  for 1997
and 1998: risk-free interest rate of 5.25%; no dividends; a volatility factor of
the  expected  market  price  of  the  Company's  common  stock  of  .40  and  a
weighted-average  expected life of the options of  approximately 5 years in 1997
and 4 years in 1998.

         The  Black-Scholes  option  valuation  model was  developed  for use in
estimating  the fair value of traded  options that have no vesting  restrictions
and are fully  transferable.  In addition,  option  valuation models require the
input of highly  subjective  assumptions  including  the  expected  stock  price
volatility.  Because the Company's  employee stock options have  characteristics
significantly different from those of traded options, and because changes in the
subjective input assumptions can materially  affect the fair value estimate,  in
management's  opinion, the existing models do not necessarily provide a reliable
single measure of the fair value of its employee stock options.

      For purposes of the pro forma disclosure,  the estimated fair value of the
options is amortized to expense over the options' vesting period.

14.      Operating Leases

      The Company  leases  office space and  equipment  located  throughout  the
United States and worldwide.  Substantially  all office space leases provide for
the  Company to pay a pro rata  share of annual  increases  above a stated  base
amount of the  landlords'  related  real estate  taxes and  operating  expenses.
Management expects that in the normal course of business,  operating leases will
be renewed or replaced by other operating leases.

     The following is a schedule of the annual minimum rental payments  required
under the operating leases that have initial or remaining  non-cancellable lease
terms in excess of one year as of December 31, 1998:

was approximately $7,672, $7,468 and $8,451, respectively.

15.      Retirement Plan

         The Company maintains  tax-deferred  savings plans under Section 401(k)
of the  Internal  Revenue Code to provide  retirement  benefits for all eligible
employees  (the "Plan").  Employees may  voluntarily  contribute a percentage of
their  annual  compensation  to the Plan,  subject to Internal  Revenue  Service
limitations.   The  Company  may,  but  has  no  obligation  to,  make  matching
contributions.  In addition,  the Company may, but has no obligation  to, make a
discretionary   contribution  to  the  Plan.  Discretionary   contributions  are
allocated to participants' accounts in proportion to their compensation.  Rights
to  benefits  provided  by the  Company's  discretionary  contributions  vest as
follows: 40% after two years, 70% after three years and 100% after four years of
service. Participants are fully vested in their voluntary contributions.

     PHB  sponsors two defined  contribution  plans for its  employees:  the PHB
Profit  Sharing Plan and the PHB 401(k) plan.  The plans cover all  employees of
PHB who meet the eligibility requirements.  The Profit Sharing Plan permits only
employer  discretionary profit sharing  contributions.  Eligible participants of
the 401(k) savings plan may contribute up to 15% of their qualified compensation
annually, subject to federal limitations.

     The Company is currently  evaluating the current retirement plans mentioned
above as well as those  plans under its other  subsidiaries  in order to combine
those of the merged  subsidiaries with their own. The Company's expenses related
to its discretionary  matching and other contributions under all plans for 1996,
1997 and 1998 were approximately $2,612, $2,628 and $925, respectively.

16.   Divestitures / Sale of Assets

     On December 23, 1996, the Company caused Putnam,  Hayes & Bartlett  Limited
("PHB Ltd"), the Company's U.K. subsidiary,  to cease operations and appointed a
liquidator to wind up PHB Ltd's affairs.  The operating  results of PHB Ltd have
been included in the Company's  consolidated  statements of operations until the
liquidation  date. The Company  recognized the net amount due as of December 31,
1996,  in  connection  with the  liquidation  of PHB Ltd as a  current  asset of
$2,172.  This  amount  represented  management's  estimate  of the net  proceeds
ultimately  expected to be recovered upon collection of accounts receivable from
clients and payments of obligations  to creditors.  As of December 31, 1997, the
Company estimated that $328 of the $2,172 was not collectable.  Of the Company's
loss of $663  recognized in 1996 in connection  with the liquidation of PHB Ltd,
$549  represented  cumulative  foreign  currency  transaction  losses  which had
previously been recorded as a separate component of the Company's  stockholders'
equity.  

     On September 30, 1998,  the Company sold certain assets of a portion of its
public sector  consulting  practice due to conflicts of interest  resulting from
the  Company's  business   combinations  (see  Note  3).  As  a  result  of  the
transaction,  the Company sold assets for  approximately  $2,855  resulting in a
gain of approximately $282 which was included in other income.

     In December 1998, the Company made the decision to cease  operations in its
financial advisory services business, HB Capital, Inc., resulting in expenses of
approximately $1.8 million (see Note 18).

17.      Commitments and Contingencies

Cost Subject to Audit

      Under its United States  government  contracts,  the Company is subject to
audit by the  Defense  Contract  Audit  Agency,  whose  audits  could  result in
adjustments of amounts previously billed.  Management  believes that the results
of such  audits  will  not  have a  material  adverse  effect  on the  Company's
financial position or results of operations.


Financial Instruments and Risk Management

      The  Company  operates  around  the world  principally  in  United  States
currency.  The Company may reduce any  periodic  exposures  to  fluctuations  in
foreign exchange rates by creating  offsetting  ("hedge")  positions through the
use of derivative  financial  instruments.  The Company  currently  does not use
derivative financial instruments for trading or speculative purposes, nor is the
Company a party to leverage  derivatives.  The Company  regularly  monitors  any
foreign currency exposures and ensures that hedge contract amounts do not exceed
the amounts of the underlying exposures. The Company had no open hedge positions
at December 31, 1997 or 1998.

Financial  instruments  that  potentially  subject  the  Company to  significant
concentrations  of credit risk consist  principally of cash and cash equivalents
and trade accounts receivable.

      The Company  maintains cash and cash  equivalents  with various  financial
institutions.  These  financial  institutions  are  located  in  many  different
countries  throughout the world,  and the Company's  policy is designed to limit
exposure with any one institution.  As part of its cash management process,  the
company performs  periodic  evaluations of the relative credit standing of these
financial institutions.

     At December  31, 1997 and 1998,  cash of  approximately  $2,502 and $4,087,
respectively, was located in foreign bank accounts.


Major Customers

      At December 31, 1997 and 1998,  included in accounts receivable was $9,143
and $12,017,  respectively,  due from agencies of the United States  government.
Credit risk with respect to the remaining trade accounts receivable is generally
diversified  due to the  large  number  of  entities  comprising  the  Company's
customer base and their dispersion  across  different  industries and countries.
The Company  performs  ongoing credit  evaluations  of its customers'  financial
condition.

      The Company generates revenues from contracts with government agencies and
private companies within the United States and worldwide.  During 1996, 1997 and
1998,  the  Company  recognized  approximately  $25,997,  $31,792  and  $38,501,
respectively,  of its revenue from the United  States  Agency for  International
Development  ("USAID"),  a U.S. government agency.  Revenues earned from foreign
customers, both commercial and governmental,  were approximately $10,479, 14,031
and $19,232 for the years ended December 31 1996, 1997 and 1998, respectively.

18.    Merger Related and Other Nonrecurring Costs

      Merger  related and other  nonrecurring  costs were recorded in connection
with the business  combinations  described in Note 2, and impairments  resulting
from the Company's  evaluation  of certain  assets.  The following  represents a
detail of merger related and other nonrecurring costs: <TABLE> <CAPTION>


                                                                           For the years ended December 31,
                                                                                1997              1998
                                                                          --------------    ----------------

       Merger related costs                                                     $ 1,235              $ 6,495

       Impairment of software development costs                                       -                1,107

       Impairment of investments and related infrastructure
       related to termination of financial advisory services
       operations
                                                                                      -                1,780
                                                                         ---------------    -----------------
       Total                                                                    $ 1,235              $ 9,382
                                                                         ===============    =================
      </TABLE>


     Merger  related costs consist  primarily of direct costs such as investment
banking, legal, accounting,  and filing fees as well as consolidation costs from
the closing of duplicate locations, realigning regional and corporate functions,
and reducing  personnel.  At December 31, 1998,  the  accompanying  consolidated
balance sheet  includes  accrued  merger  related  costs of $546,  classified as
accrued expenses,  consisting of involuntary  employee termination costs of $171
and facility related expenses of $375.

      Certain software development costs were impaired due to the duplication of
technologies  resulting from the Company's  business  combinations and its joint
venture  with  Cap  Gemini.  Management  determined  that as a  result  of these
transactions  certain  capitalized  software  balances would not generate future
cash flows.  Consequently,  management  determined that the value of the related
assets had been impaired and has recorded a write off of approximately $1,107.

     During  the fourth  quarter of 1998,  management  determined  that  certain
investments  held by the Company and the related  infrastructure  which  managed
such  investments,  were  impaired.  Accordingly,  management  decided  to cease
operations of its financial  advisory  services  operations and determined  that
certain  investments were fully impaired and recognized a loss of $1,780,  which
included the write off of a $1,000 note receivable (see Note 9). At December 31,
1998, the balance sheet included costs of $616  classified as accrued  expenses,
consisting of legal expenses of $140,  involuntary employee termination costs of
$170,  lease  termination  and other  facility  costs of $200, and other general
accrued expenses of $106.




19.   Subsequent Events

On February 8, 1999, the Company acquired all of the outstanding stock of Lacuna
Consulting Limited, a United Kingdom corporation,  in exchange for 65,000 shares
of the  Company's  common  stock.  The  acquisition  was accounted for using the
purchase method.

                                                    EXHIBIT 4.3




                                           REGISTRATION RIGHTS AGREEMENT


         THIS REGISTRATION  RIGHTS AGREEMENT (this  "Agreement") is entered into
this 23rd day of February,  1998, by and between HAGLER BAILLY, INC., a Delaware
corporation  (the  "Acquiror"),  and  Michael J.  Beck,  acting by virtue of the
Merger  Agreement  (as  hereinafter   defined)  as  the   attorney-in-fact   and
representative  (the  "Stockholders'  Representative")  of the stockholders (the
"Company  Stockholders")  of TB&A  Group,  Inc.,  a  Delaware  corporation  (the
"Company").

         WHEREAS, on or about the date hereof, the Company  Stockholders have or
will have  become the owners of shares of  Acquiror's  common  stock,  par value
$0.01 per share ("Acquiror Common Stock");

         WHEREAS, as part of the inducement for the parties hereto to enter into
and perform the Agreement and Plan of Merger (the "Merger Agreement"),  dated as
of  January  ___,  1998,  the  parties  hereto  have  agreed to enter  into this
Agreement  in order to provide,  among other  things,  for certain  registration
rights;

         NOW, THEREFORE,  the parties hereto, in consideration of the foregoing,
the mutual  covenants and agreements  hereinafter set forth,  and other good and
valuable  consideration,  the  receipt  and  sufficiency  of  which  hereby  are
acknowledged, agree as follows:

     1. Term.  This Agreement  shall  terminate on the date on which the Company
Stockholders could sell all of their Registerable  Securities to the public in a
single  transaction  pursuant to the provisions of Rule 144 under the Securities
Act, provided, however, the indemnification provisions of Section 6 hereof shall
survive the termination of this Agreement.

     2. Piggyback Registration Rights.

     (a) If at any time or times Acquiror  proposes to make a registered  public
offering  of any of its  securities  (whether  for  its own  account  or for the
account of others) under the  Securities  Act,  Acquiror shall (i) promptly give
written notice of the proposed  registration to each of the Company Stockholders
(such  notice to  include  the number of shares  the  Company or other  security
holders propose to register and, if known, the name of the proposed underwriter)
and (ii) use its best efforts to include in such  registration  (and any related
qualification  under Blue Sky laws and/or other compliance) all the Registerable
Securities  specified  in a written  request  or  requests  made by any  Company
Stockholder  within 30 days after the receipt of such notice from the Company (a
"Piggyback  Registration").  Such written request may specify all or a part of a
holder's Registerable Securities,  provided, however, that (x) Acquiror will not
be required to effect a Piggyback  Registration if it is registering  securities
on Forms S-8 or S-4 (or any successor forms) or other SEC registration  form not
suitable  for  inclusion  of shares  of  selling  stockholders  for offer to the
public,  and (y) Acquiror may  withdraw any proposed  registration  statement or
offering of securities under this Section 2 at any time without liability to any
Company  Stockholder,  in which case  Acquiror  will not be required to effect a
registration.

     (b) If a Piggyback  Registration is an underwritten primary registration on
behalf of Acquiror,  and the managing  underwriter  advises  Acquiror in writing
that in the managing underwriter's opinion the number of securities requested to
be  included  in such  registration  exceeds the number that can be sold in such
offering without adversely affecting the marketability of the offering, Acquiror
shall include in such offering first, the securities of Acquiror  proposed to be
sold by Acquiror  and second,  all other  securities  held by security  holders,
including  the  Registerable  Securities,  requested  to  be  included  in  such
registration by all other security holders (including the Company Stockholders),
pro rata among such security holders,  based upon the number of shares requested
by each to be  included  in  such  registration.  In  addition,  if a  Piggyback
Registration is an underwritten primary registration on behalf of Acquiror,  the
selling  Company  Stockholders  agree to sell their  Acquiror  Common Stock,  if
Acquiror so requests, on the same basis as the other securities included in such
registration  are  being  sold  and the  underwriter  or  underwriters  for such
registration  shall be selected by Acquiror.  If a Piggyback  Registration is an
underwritten secondary  registration on behalf of selling stockholders,  and the
managing   underwriter   advises  Acquiror  in  writing  that  in  the  managing
underwriter's  opinion the number of securities requested to be included in such
registration  exceeds  the  number  that  can be sold in such  offering  without
adversely  affecting  the  marketability  of the offering,  then Acquiror  shall
include in such offering first,  the securities of Acquiror  proposed to be sold
by  the   stockholders   requiring  or  demanding  that  Acquiror   effect  such
registration  and  second,  all  other  securities  held  by  security  holders,
including  the  Registerable  Securities,  requested  to  be  included  in  such
registration by all other security holders (including the Company Stockholders),
pro rata among such security holders,  based upon the number of shares requested
by each to be included in such registration.

                           3.       Registration Procedures.

     (a) The Company shall have no obligation to include Registerable Securities
owned by the Company  Stockholders  in a registration  statement for a Piggyback
Registration,  unless  and until the  Company  Stockholders  have  furnished  to
Acquiror all  information  and  statements  about or  pertaining  to the Company
Stockholders in such reasonable detail and on such timely basis as is reasonably
deemed by Acquiror to be necessary or  appropriate  for the  preparation  of the
registration statement.
     (b) Whenever the Company  Stockholders  have  requested  that  Registerable
Securities be registered in a Piggyback  Registration,  Acquiror shall keep each
Company Stockholder advised in writing as to the initiation of each registration
and as to the  completion  thereof.  As  expeditiously  as reasonably  possible,
Acquiror
shall:

     (1) prepare and file with the SEC a registration  statement with respect to
such  Registerable  Securities and use its reasonable  best efforts,  subject to
Section  2(a)(y),  to cause  such  registration  statement  to become  effective
(provided  that before  filing a  registration  statement or  prospectus  or any
amendments or supplements thereto, Acquiror will furnish to one counsel selected
by the  holders of a majority  of the  Registerable  Securities  covered by such
registration  statement copies of all such documents proposed to be filed, which
documents will be subject to the review of such counsel);

     (2) keep such  registration  statement  effective  for a period of not less
than  nine  months  or  until  the  Company   Stockholders  have  completed  the
distribution described in such registration  statement,  whichever occurs first,
and amend or supplement such registration statement and the prospectus contained
therein from time to time to the extent  necessary to comply with the provisions
of the Securities Act and applicable  state  securities laws with respect to the
disposition of all securities covered by such registration statement during such
period in accordance  with the intended  methods of  disposition  by the sellers
thereof set forth in such registration statement;

     (3)  furnish  to the  Company  Stockholders  the  number  of copies of such
registration  statement,  each amendment and supplement thereto,  the prospectus
contained  in  such   registration   statement   (including   each   preliminary
prospectus),  and such other documents as the Company  Stockholders from time to
time may reasonably request;

     (4) use its best efforts to register or qualify such shares under the state
blue sky or securities  ("Blue Sky") laws of such  jurisdictions  as any Company
Stockholder  reasonably  requests,  and to do any and all other  acts and things
that may be reasonably necessary or advisable to enable the Company Stockholders
to consummate the  disposition of such shares in such  jurisdictions;  provided,
however,  that  Acquiror  will not be required to do any of the  following:  (i)
qualify  generally  to do business in any  jurisdiction  where it is not then so
qualified or otherwise required to be so qualified but for this Section 3(b), or
(ii) take any action which would subject it to the service of process in actions
other than those arising out of such registration;

     (5) notify the Company Stockholders, at any time when a prospectus relating
to the Registerable  Securities is required to be delivered under the Securities
Act, of the occurrence of any event as a result of which the prospectus included
in any such  registration  statement  contains an untrue statement of a material
fact or omits  to  state a  material  fact  required  to be  stated  therein  or
necessary to make the statements therein in the light of the circumstances under
which they were made,  not  misleading,  and prepare and furnish to such Company
Stockholders  a reasonable  number of copies of a supplement or amendment to the
prospectus  as  may  be  necessary  so  that,  as  thereafter  delivered  to the
purchasers of such shares,  the prospectus will not contain an untrue  statement
of a material  fact or omit to state any fact  required to be stated  therein or
necessary to make the statements therein, in the light of the circumstances then
existing, not misleading;

     (6) cause all such Registerable  Securities to be listed on each securities
exchange on which similar  securities issued by Acquiror are then listed and, if
not so listed,  to be listed on the National  Association of Securities  Dealers
("NASD")  Automated  Quotation  ("Nasdaq")  system  and, if listed on the Nasdaq
system,  use its  reasonable  best  efforts  to secure  designation  of all such
Registerable  Securities  covered  by such  registration  statement  as a Nasdaq
"national  market system security" within the meaning of Rule 11Aa2-1 of the SEC
or,  failing  that,  to  secure  Nasdaq   authorization  for  such  Registerable
Securities;

     (7)  provide a  transfer  agent  and  registrar  for all such  Registerable
Securities  (if Acquiror does not already have such an agent) not later than the
effective date of such registration statement;

     (8) enter into such customary agreements (including underwriting agreements
in customary  form) and take all such other actions as the holders of a majority
of  the  Registerable  Securities  being  sold  or  the  underwriters,  if  any,
reasonably  request in order to expedite or facilitate  the  disposition of such
Registerable Securities (including, without limitation,  effecting a stock split
or a combination of shares);

     (9) make  available all financial and other  records,  pertinent  corporate
documents and  properties of Acquiror for  inspection  by, and cause  Acquiror's
officers,  directors,  employees  and  independent  accountants  to  supply  all
information reasonably requested by, any seller of Registerable Securities,  any
underwriter  participating  in any  disposition  pursuant  to such  registration
statement  and any  attorney,  accountant  or other  agent  retained by any such
seller or  underwriter  in  connection  with  such  registration  statement  who
executes  any  reasonable  confidentiality  agreement  that  may  be  reasonably
requested  by  Acquiror  or who is  bound  by  fiduciary  duty  or  professional
responsibility to preserve the confidentiality thereof;


     (10)  otherwise  use  its  reasonable  best  efforts  to  comply  with  all
applicable  rules and regulations of the SEC, and make available to its security
holders, as soon as reasonably  practicable,  an earnings statement covering the
period of at least 12 months  beginning  with the first day of Acquiror's  first
full calendar  quarter after the effective date of the  registration  statement,
which  earnings  statement  shall satisfy the provisions of Section 11(a) of the
Securities Act and Rule 158 thereunder; and

     (11) use its reasonable best efforts to cause such Registerable  Securities
covered by such registration statement to be registered with or approved by such
other  governmental  agencies or  authorities  as may be necessary to enable the
sellers thereof to consummate the disposition of such Registerable Securities.

                           4.       Holdback Agreements.

     (a)  Each  holder  of  Registerable  Securities  who  is  included  in  the
Registration  Statement  agrees not to effect any  public  sale or  distribution
(including sales pursuant to Rule 144) of equity securities of Acquiror,  or any
securities  convertible into or exchangeable or exercisable for such securities,
during the seven days prior to and the 90-day period  beginning on the effective
date  of any  underwritten  Piggyback  Registration  (except  as  part  of  such
underwritten  registration),  unless the  underwriters  managing the  registered
public offering otherwise agree.

     (b) The Acquiror  agrees (i) not to effect any public sale or  distribution
of its equity securities,  or any securities convertible into or exchangeable or
exercisable for such  securities,  during the seven days prior to and during the
90-day period  beginning on the  effective  date of any  underwritten  Piggyback
Registration  (except as part of such  underwritten  registration or pursuant to
registrations  on Form  S-8 or  Form  S-4 or any  successor  form),  unless  the
underwriters  managing the registered public offering  otherwise agree, and (ii)
to use all  reasonable  efforts to cause  each  Person  that,  during the 30-day
period prior to the effective date of such Piggyback Registration,  holds shares
of Acquiror  Common Stock (or  securities  convertible  into or  exercisable  or
exchangeable  for Acquiror  Common  Stock)  received  from Acquiror in an amount
which,  on a fully  diluted  basis,  exceeds 1% of  Acquiror  Common  Stock then
outstanding (on a fully diluted  basis),  to agree not to effect any public sale
or  distribution  (including  sales pursuant to Rule 144) of any such securities
during  such  period  (except  as  part of such  underwritten  registration,  if
otherwise  permitted),  unless the underwriters  managing the registered  public
offering otherwise agree.

                           5.       Registration Expenses.

     (a) If Registerable Securities are included in a registration statement for
a Piggyback  Registration,  then each selling Company  Stockholder shall pay all
transfer  taxes,  if any,  relating  to the  sale of its  shares,  the  fees and
expenses  of its own  counsel,  and its pro  rata  portion  of any  underwriting
discounts or commissions or the equivalent thereof.

     (b) If Registerable Securities are included in a registration statement for
a Piggyback  Registration,  then except for the fees and  expenses  specified in
Section  5(a)  hereof  and  except  as  provided  below  in this  Section  5(b),
regardless of whether any registration  statement  becomes  effective,  Acquiror
shall pay all expenses incident to a Piggyback Registration,  including, without
limitation,  all registration,  qualification and filing fees, fees and expenses
of compliance  with Blue Sky laws,  underwriting  discounts,  fees, and expenses
(other  than the  Company  Stockholders'  pro rata  portion of any  underwriting
discounts  or  commissions  or  the  equivalent  thereof),   printing  expenses,
messenger and delivery  expenses,  and fees and expenses of counsel for Acquiror
and all independent  certified public  accountants and other persons retained by
Acquiror.

                           6.       Indemnification.

     (a) The Acquiror agrees to indemnify,  to the extent permitted by law, each
holder of Registerable Securities,  each Person who controls such holder (within
the meaning of Section 15 of the  Securities  Act or Section 20 of the  Exchange
Act) and their respective officers,  directors,  partners, employees, agents and
representatives,  against all losses, claims, damages,  liabilities and expenses
("Losses")  arising out of or based upon any untrue or alleged untrue  statement
of  material  fact  contained  in any  registration  statement,  prospectus,  or
preliminary  prospectus  or any amendment  thereof or supplement  thereto or any
omission or alleged omission of a material fact required to be stated therein or
necessary to make the statements  therein,  in light of the circumstances  under
which they were made, not  misleading,  except insofar as the same are caused by
or contained in any information  furnished in writing to Acquiror by such holder
expressly for use therein or by such  holder's  failure to deliver a copy of the
registration  statement or prospectus or any amendments or  supplements  thereto
after Acquiror has furnished  such holder with a sufficient  number of copies of
the same and  except  insofar  as the same are  caused  by or  contained  in any
prospectus  if such  holder  failed to send or deliver a copy of any  subsequent
prospectus or prospectus  supplement  which would have  corrected such untrue or
alleged untrue  statement of material fact or such omission or alleged  omission
of a material fact with or prior to the delivery of written  confirmation of the
sale by such holder after  Acquiror has furnished  such holder with a sufficient
number of  copies of the same.  In  connection  with an  underwritten  offering,
Acquiror  will  indemnify  such  underwriters,  each  Person who  controls  such
underwriters  (within the meaning of Section 15 of the Securities Act or Section
20 of the Exchange  Act) and their  respective  officers,  directors,  partners,
employees,  agents and representatives to the same extent as provided above with
respect to the indemnification of the holders of Registerable Securities.

     (b) In  connection  with any  registration  statement  in which  holders of
Registerable  Securities  are  participating,  each such holder will  furnish to
Acquiror in writing  such  information  and  affidavits  as Acquiror  reasonably
requests  for  use  in  connection  with  any  such  registration  statement  or
prospectus and, to the extent  permitted by law, will indemnify  Acquiror,  each
Person who controls Acquiror (within the meaning of Section 15 of the Securities
Act or Section 20 of the Exchange Act) and their respective officers, directors,
partners,  employees,  agents and representatives against any Losses arising out
of or based upon any  untrue or  alleged  untrue  statement  of a material  fact
contained in any registration statement,  prospectus,  or form of prospectus, or
arising out of or based upon any omission or alleged omission of a material fact
required to be stated  therein or necessary to make the statements  therein,  in
light of the  circumstances  under which they were made, not misleading,  to the
extent, but only to the extent,  that such untrue or alleged untrue statement is
contained in, or such  omission or alleged  omission is required to be contained
in, any information so furnished in writing by such holder to Acquiror expressly
for use in such registration  statement or prospectus and that such statement or
omission  was  relied  upon by  Acquiror  in  preparation  of such  registration
statement, prospectus or form of prospectus; provided, however, that such holder
of  Registerable  Securities  shall not be liable in any such case to the extent
that the holder has  furnished in writing to the Company  prior to the filing of
any such registration statement or prospectus or amendment or supplement thereto
information  expressly for use in such  registration  statement or prospectus or
any  amendment or  supplement  thereto  which  corrected or made not  misleading
information  previously  furnished to Acquiror,  and Acquiror  failed to include
such information  therein. In no event shall the liability of any selling holder
of Registerable Securities hereunder be greater in amount than the dollar amount
of the proceeds  (net of payment of all  expenses)  received by such holder upon
the sale of the  Registerable  Securities  giving  rise to such  indemnification
obligation.  Such indemnity shall remain in full force and effect  regardless of
any investigation made by or on behalf of such indemnified party.

     (c)  If  any  Person  shall  be  entitled  to  indemnity  hereunder,   such
     indemnified  party  shall give prompt  notice to the party or parties  from
     which such  indemnity is sought of the  commencement  of any action,  suit,
     proceeding or investigation or written threat thereof  ("Proceeding")  with
     respect  to  which  such  indemnified   party  seeks   indemnification   or
     contribution  pursuant hereto;  provided,  however,  that the failure to so
     notify the indemnifying  parties shall not relieve the indemnifying parties
     from any  obligation or liability  hereunder  except to the extent that the
     indemnifying parties have been prejudiced by such failure. The indemnifying
     parties shall have the right,  exercisable  by giving  written notice to an
     indemnified  party  promptly  after the receipt of written notice from such
     indemnified  party  of such  Proceeding,  to  assume,  at the  indemnifying
     parties'  expense,  the  defense  of  any  such  Proceeding,  with  counsel
     reasonably satisfactory to such indemnified party; provided,  however, that
     an indemnified party or parties (if more than one such indemnified party is
     named in any Proceeding) shall have the right to employ separate counsel in
     any such Proceeding and to participate in the defense thereof, but the fees
     and  expenses of such counsel  shall be at the expense of such  indemnified
     party or parties  unless the parties to such  Proceeding  include  both the
     indemnified  party or parties and the  indemnifying  party or parties,  and
     there exists,  in the opinion of the parties'  counsel,  a conflict between
     one or more indemnifying  parties and one or more indemnified  parties,  in
     which case the indemnifying  parties shall, in connection with any one such
     Proceeding or separate but substantially  similar or related Proceedings in
     the same  jurisdiction,  arising  out of the same  general  allegations  or
     circumstances,  be liable  for the fees and  expenses  of not more than one
     separate firm of attorneys (together with appropriate local counsel) at any
     time for  such  indemnified  party or  parties.  If an  indemnifying  party
     assumes the defense of such Proceeding,  the indemnifying  parties will not
     be subject to any  liability  for any  settlement  made by the  indemnified
     party without its or their  consent  (such  consent not to be  unreasonably
     withheld).

     (d) If the indemnification provided for in this Section 6 is unavailable to
     an indemnified  party or is  insufficient  to hold such  indemnified  party
     harmless for any Losses in respect of which this Section 6 would  otherwise
     apply by its terms,  then each  applicable  indemnifying  party, in lieu of
     indemnifying  such  indemnified  party,  shall  have a  joint  and  several
     obligation to contribute to the amount paid or payable by such  indemnified
     party as a result of such Losses,  in such  proportion as is appropriate to
     reflect the relative fault of the indemnifying  party, on the one hand, and
     such indemnified  party, on the other hand, in connection with the actions,
     statements  or omissions  that resulted in such Losses as well as any other
     relevant equitable considerations.  The relative fault of such indemnifying
     party, on the one hand, and indemnified  party, on the other hand, shall be
     determined  by  reference  to,  among other  things,  whether any action in
     question,  including any untrue or alleged  untrue  statement of a material
     fact or omission or alleged  omission  to state a material  fact,  has been
     taken by, or relates to information supplied by, such indemnifying party or
     indemnified party, and the parties' relative intent,  knowledge,  access to
     information  and  opportunity  to  correct  or  prevent  any  such  action,
     statement or omission. The amount paid or payable by a party as a result of
     any Losses  shall be deemed to include  any legal or other fees or expenses
     incurred by such party in  connection  with any  Proceeding,  to the extent
     such party would have been indemnified for such expenses under Section 6(c)
     if the  indemnification  provided for in Section 6(a) or 6(b) was available
     to such  party.  The  parties  hereto  agree  that it would not be just and
     equitable if contribution  pursuant to this Section 6(d) were determined by
     pro rata allocation or by any other method of allocation that does not take
     account of the  equitable  considerations  referred  to in the  immediately
     preceding paragraph. Notwithstanding the provision of this Section 6(d), an
     indemnifying  party  that is a selling  holder of  Registerable  Securities
     shall not be required to  contribute  any amount in excess of the amount by
     which the net  proceeds  received by such  indemnifying  party  exceeds the
     amount of any  damages  that such  indemnifying  party has  otherwise  been
     required to pay by reasons of such untrue or alleged  untrue  statement  or
     omission   or   alleged   omission.   No  person   guilty   of   fraudulent
     misrepresentation  (within the meaning of Section  11(f) of the  Securities
     Act) shall be entitled to  contribution  from any Person who was not guilty
     of such fraudulent misrepresentation.

     7.  Information by Holder.  Each holder of  Registerable  Securities  shall
     furnish to the Acquiror and to the managing  underwriter  such  information
     regarding such holder and the  distribution  proposed by such holder as the
     Acquiror or the managing  underwriter may reasonably request in writing and
     as  shall be  reasonably  required  in  connection  with any  registration,
     qualification or compliance referred to in Section 3.

     8. Rule 144  Reporting.  With a view to making  available  the  benefits of
     certain  rules and  regulations  of the SEC which  may  permit  the sale of
     restricted  securities (as that term is defined in Rule 144(a)(3) under the
     Securities Act) to the public without registration, Acquiror agrees to :

     (a) use its  best  efforts  to file  with the SEC in a  timely  manner  all
     reports and other  documents  required of the Company under the  Securities
     Act and the Exchange Act; and

     (b) so long as any holder of  Registerable  Securities  owns any restricted
     securities,  furnish to such holder upon request a written statement by the
     Acquiror  as to its  compliance  with  the  reporting  requirements  of the
     Securities  Act and the Exchange  Act, a copy of the most recent  annual or
     quarterly  report of the Acquiror,  and such other reports and documents so
     filed as a holder may reasonably  request in availing itself of any rule or
     regulation  of the SEC  allowing  such  holder to sell any such  securities
     without registration.

     9.  Representations  and  Warranties  of  Acquiror.   The  Acquiror  hereby
     represents and warrants to the Company Stockholders, as of the date hereof,
     as follows:

     this Agreement,  to perform its obligations hereunder and to consummate the

     are necessary to authorize this Agreement or to consummate the transactions

     enforceability  may be limited by bankruptcy,  insolvency,  reorganization,
     moratorium and other similar laws of general  applicability  relating to or
     affecting  creditors'  rights  generally and by the  application of general
     principles of equity.

     (b) The  execution  and delivery of this  Agreement by Acquiror do not, and

     ordinance, rule, regulation,  order, judgment or decree whether national or
     foreign,  applicable  to  Acquiror or its assets and  properties,  or (iii)
     result in any  breach of or  constitute  a  default  under any note,  bond,
     mortgage, indenture, contract, agreement, lease, license, permit, franchise

     register  any  equity   securities  of  the  Company,   or  any  securities
     convertible or exchangeable into or exercisable for such securities,  which

     Stockholder may not transfer or assign its rights hereunder, in whole or in

     Company Stockholder.

     15.  Successors and Assigns.  This Agreement  shall inure to the benefit of
     and be binding upon the  successors  and  permitted  assigns of each of the
     parties, including,  without limitation and without the need for an express
     assignment,   Affiliates  of  the  Company  Stockholders.  If  any  Company
     Stockholder shall acquire Registerable  Securities,  in any manner, whether
     by operation of law or otherwise,  such  Registerable  Securities  shall be

     provision of this  Agreement is held to be  prohibited  by or invalid under
     applicable law, such provision  shall be ineffective  only to the extent of
     such prohibition or invalidity,  without invalidating the remainder of this
     Agreement.

     17.  Counterparts.  This  Agreement  may  be  executed  in  any  number  of
     counterparts  and by the parties hereto in separate  counterparts,  each of
     which when so executed  shall be deemed to be an original  and all of which
     taken together shall constitute one and the same agreement.

     18. Headings.  The headings in this Agreement are for convenience reference
     only and shall not limit or otherwise affect the meaning hereof.

     19.  Governing Law. This  Agreement  shall be governed by, and construed in

     to the conflicts of laws provisions thereof.

     20. Specific  Performance.  The parties hereto acknowledge that there would
     be no  adequate  remedy at law if any  party  fails to  perform  any of its
     obligations  hereunder,  and accordingly agree that each party, in addition
     to any other remedy to which it may be entitled at law or in equity,  shall
     be entitled to compel specific  performance of the obligations of any other
     party under this  Agreement in accordance  with the terms and conditions of
     this  Agreement  in any court of the  United  States  or any State  thereof
     having jurisdiction.

     expression  or their  agreement and intended to be a complete and exclusive

                          STOCKHOLDERS' REPRESENTATIVE

                             By: /s/ Michael J. Beck
                              Name: Michael J. Beck







                                                    EXHIBIT 4.4



                                           REGISTRATION RIGHTS AGREEMENT

                 THIS  REGISTRATION   RIGHTS  AGREEMENT  (this  "Agreement')  is
entered  into as of this  17th day of  November,  1998,  by and  between  HAGLER
BAILLY,  INC.,  a  Delaware  corporation  ("HAGLER  BAILLY"),   the  undersigned
stockholders  of FIELDSTON  PUBLICATIONS,  INC., a Maryland  corporation and THE
FIELDSTON  COMPANY,  a District of Columbia  corporation ("TFC" and collectively
with  Fieldston   Publications,   Inc.,  the  "FIELDSTON   Companies")  and  TFC
(collectively the "FIELDSTON Stockholders").

                 WHEREAS,  on the date hereof,  the FIELDSTON  Stockholders have
become the owners of shares of HAGLER  BAILLY's,  common stock,  par value $0.01
per share ("HAGLER BAILLY Common Stock ");

                 WHEREAS,  as part of the  inducement  for the parties hereto to
enter into and perform the Acquisition Agreement (the "Acquisition  Agreement"),
dated as of November 17, 1998, the parties hereto have agreed to enter into this
Agreement in order to provide,  among other things, for certain registration and
"tag-along" rights;

                 NOW,  THEREFORE,  the parties hereto,  in  consideration of the
foregoing,  the mutual covenants and agreements hereinafter set forth, and other
good and valuable consideration, the receipt and sufficiency of which hereby are
acknowledged, agree as follows:

                 1. Term.  This Agreement  shall  terminate on the date on which
the Fieldston  Stockholders could sell all of their  Registerable  Securities to
the public in a single transaction  pursuant to the provisions of Rule 144 under
the Securities Act, provided, however, the indemnification provisions of Section
6 hereof shall survive the termination of this Agreement.

                 2.       Piggyback Registration Rights.

                  (a) If at any time or times HAGLER  BAILLY  proposes to make a
registered public offering of any of its securities (whether for its own account
or for the account of others) under the Securities  Act, HAGLER BAILLY shall (i)
promptly  give  written  notice  of the  proposed  registration  to  each of the
FIELDSTON  Stockholders  (such  notice to include  the  number of shares  HAGLER
BAILLY or other security  holders propose to register and, if known, the name of
the  proposed  underwriter)  and (ii) use its best  efforts  to  include in such
registration  (and any related  qualification  under Blue Sky laws and/or  other
compliance) all the  Registerable  Securities  specified in a written request or
requests made by any FIELDSTON  Stockholder  within 30 days after the receipt of
such  notice from  HAGLER  BAILLY (a  "Piggyback  Registration").  Such  written
request  may  specify  all  or a part  of a  holder's  Registerable  Securities,
provided,  however,  that (x) HAGLER  BAILLY  will not be  required  to effect a
Piggyback  Registration if it is registering  securities on Forms S-8 or S-4 (or
any successor forms) or another SEC registration form not suitable for inclusion
of shares of selling stockholders for offer to the public, and (y) HAGLER BAILLY
may withdraw any proposed registration statement or offering of securities under
this Section 2 at any time without  liability to any FIELDSTON  Stockholder,  in
which case HAGLER BAILLY will not be required to effect a registration.

                 (b) If a  Piggyback  Registration  is an  underwritten  primary
registration on behalf of HAGLER BAILLY,  and the managing  underwriter  advises
HAGLER BAILLY in writing that in the managing  underwriter's  opinion the number
of securities  requested to be included in such registration  exceeds the number
that can be sold in such offering without adversely  affecting the marketability
of the  offering,  HAGLER  BAILLY  shall  include in such  offering  first,  the
securities of HAGLER BAILLY proposed to be sold by HAGLER BAILLY and second, all
other   securities  held  by  security   holders,   including  the  Registerable
Securities,  requested to be included in such  registration by an other security
holders  (including  the FIELDSTON  Stockholders),  pro rata among such security
holders,  based upon the number of shares  requested  by each to be  included in
such  registration.  If a  Piggyback  Registration  is an  underwritten  primary
registration  on behalf of HAGLER  BAILLY,  the selling  FIELDSTON  Stockholders
agree to sell their HAGLER BAILLY Common Stock, if HAGLER BAILLY so requests, on
the same basis as the other securities  included in such  registration are being
sold and the underwriter or underwriters for such registration shall be selected
by HAGLER  BAILLY.  If a Piggyback  Registration  is an  underwritten  secondary
registration  on behalf of selling  stockholders,  and the managing  underwriter
advises HAGLER BAILLY in writing that in the managing  underwriter's opinion the
number of securities  requested to be included in such registration  exceeds the
number  that  can be sold in  such  offering  without  adversely  affecting  the
marketability of the offering, then HAGLER BAILLY shall include in such offering
first,  the securities of HAGLER BAILLY proposed to be sold by the  stockholders
requiring or demanding that HAGLER BAILLY effect such  registration  and second,
all other  securities  held by security  holders  (including  the  Registerable,
Securities)  requested to be included in such registration by all other security
holders (including the FIELDSTON Stockholders),  pro rata among all such selling
stockholders  and  other  security  holders,  based  upon the  number  of shares
requested by each to be included in such registration.


                 3.       Registration Procedures.

                 (a)  HAGLER   BAILLY  shall  have  no   obligation  to  include
Registerable  Securities  owned by the FIELDSTON  Stockholders in a registration
statement  for  a  Piggyback  Registration,   unless  and  until  the  FIELDSTON
Stockholders  have  furnished to HAGLER BAILLY all  information  and  statements
about or pertaining to the FIELDSTON  Stockholders in such reasonable detail and
on such timely basis as is reasonably deemed by HAGLER BAILLY to be necessary or
appropriate for the preparation of the registration statement.

                 (b) Whenever the FIELDSTON  Stockholders  have  requested  that
Registerable Securities be registered in a Piggyback Registration, HAGLER BAILLY
shall  keep each  FIELDSTON  Stockholder  promptly  advised in writing as to the
initiation of each registration,  the date of effectiveness of such registration
and as to the completion thereof As expeditiously as reasonably possible, HAGLER
BAILLY shall:

     (1) prepare and file with the SEC a registration  statement with respect to
     such  Registerable  Securities and use its reasonable best efforts (subject
     to Section 2(a)(y) with respect to a Piggyback  Registration) to cause such
     registration  statement to become effective  (provided that before filing a
     registration  statement or  prospectus  or any  amendments  or  supplements
     thereto,  HAGLER BAILLY will furnish to one counsel selected by the holders
     of a majority of the Registerable  Securities  covered by such registration
     statement  copies  of  all  such  documents  proposed  to be  filed,  which
     documents will be subject to the review of such counsel);

     (2) keep such  registration  statement  effective  for a period of not less
     than nine (9) months or until the FIELDSTON Stockholders have completed the
     distribution  described in such  registration  statement,  whichever occurs
     first,  and  amend  or  supplement  such  registration  statement  and  the
     prospectus  contained  therein from time to time to the extent necessary to
     comply with the  provisions  of the  Securities  Act and  applicable  state
     securities laws with respect to the  disposition of all securities  covered
     by such  registration  statement  during such period in accordance with the
     intended  methods of disposition  by the sellers  thereof set forth in such
     registration statement;

     (3)  furnish  to the  FIELDSTON  Stockholders  the number of copies of such
     registration   statement,   each  amendment  and  supplement  thereto,  the
     prospectus  contained  in  such  registration   statement  (including  each
     preliminary  prospectus),   and  such  other  documents  as  the  FIELDSTON
     Stockholders from time to time may reasonably request;

     (4) use its best efforts to register or qualify such shares under the state
     blue sky or  securities  ("Blue  Sky")  laws of such  jurisdictions  as any
     FIELDSTON Stockholder  reasonably requests, and to do any and an other acts
     and things that may be  reasonably  necessary  or  advisable  to enable the
     FIELDSTON Stockholders to consummate the disposition of such shares in such
     jurisdictions;  provided,  however, that HAGLER BAILLY will not be required
     to do any of the  following:  (i) qualify  generally  to do business in any
     jurisdiction  where it is not then so qualified or otherwise required to be
     so qualified but for this Section 3(b), or (ii) take any action which would
     subject it to the  service of process in actions  other than those  arising
     out of such registration;

     (5)  notify  the  FIELDSTON  Stockholders,  at any time  when a  prospectus
          relating to the  Registerable  Securities  is required to be delivered
          under the  Securities  Act, of the occurrence of any event as a result
          of which the prospectus  included in any such  registration  statement
          contains an untrue  statement  of a material  fact or omits to state a
          material fact  required to be stated  therein or necessary to make the
          statements therein in the light of the circumstances  under which they
          were made, not  misleading,  and promptly  prepare and furnish to such
          FIELDSTON  Stockholders a reasonable  number of copies of a supplement
          or  amendment  to the  prospectus  as may be  necessary  so  that,  as
          thereafter  delivered to the purchasers of such shares, the prospectus
          will not  contain an untrue  statement  of a material  fact or omit to
          state any fact required to be stated  therein or necessary to make the
          statements  therein,  in the light of the circumstances then existing,
          not misleading;

     (6) cause all such Registerable  Securities to be listed on each securities
     exchange  on which  similar  securities  issued by HAGLER  BAILLY  are then
     listed and, if not so listed,  to be listed on the National  Association of
     Securities Dealers ("NASD") Automated  Quotation  ("Nasdaq") system and, if
     listed on the Nasdaq  system,  use its  reasonable  best  efforts to secure
     designation   of  all  such   Registerable   Securities   covered  by  such
     registration statement as a Nasdaq "national market system security" within
     the meaning of Rule 11Aa2-1 of the SEC or,  failing  that, to secure Nasdaq
     authorization for such Registerable Securities;

     (7)  provide a  transfer  agent  and  registrar  for all such  Registerable
     Securities (if HAGLER BAILLY does not already have such an agent) not later
     than the effective date of such registration statement;

     (8) enter into such customary agreements (including underwriting agreements
     in  customary  form) and take all such other  actions  as the  holders of a
     majority of the Registerable Securities being sold or the underwriters,  if
     any,  reasonably request in order to expedite or facilitate the disposition
     of such Registerable Securities (including, without limitation, effecting a
     stock split or a combination of shares);

     (9) make  available all financial and other  records,  pertinent  corporate
     documents  and  properties of HAGLER  BAILLY for  inspection  by, and cause
     HAGLER BAILLY's officers, directors,  employees and independent accountants
     to  supply  all  information   reasonably   requested  by,  any  seller  of
     Registerable,  Securities, any underwriter participating in any disposition
     pursuant to such  registration  statement and any  attorney,  accountant or
     other agent retained by any such seller or  underwriter in connection  with
     such  registration  statement who executes any  reasonable  confidentiality
     agreement that may be reasonably requested by HAGLER BAILLY or who is bound
     by  fiduciary  duty  or   professional   responsibility   to  preserve  the
     confidentiality thereof,

     (10)  otherwise  use  its  reasonable  best  efforts  to  comply  with  all
     applicable  rules and  regulations  of the SEC,  and make  available to its
     security holders, as soon as reasonably practicable,  an earnings statement
     covering the period of at least 12 months  beginning  with the first day of
     HAGLER BAILLY's first full calendar quarter after the effective date of the
     registration   statement,   which  earnings  statement  shall  satisfy  the
     provisions of Section I 1(a) of the Securities Act and Rule 158 thereunder;
     and

     (11) use its reasonable best efforts to cause such Registerable  Securities
     covered by such registration statement to be registered with or approved by
     such other  governmental  agencies or  authorities  as may be  necessary to
     enable  the  sellers   thereof  to  consummate  the   disposition  of  such
     Registerable Securities.

                 4.       Holdback Agreements.

                 (a) Each holder of Registerable,  Securities who is included in
the Registration  Statement agrees not to effect any public sale or distribution
(including sales pursuant to Rule 144) of equity securities of HAGLER BAILLY, or
any  securities  convertible  into  or  exchangeable  or  exercisable  for  such
securities,  during the seven days prior to and the 90-day  period  beginning on
the effective date of any underwritten Piggyback Registration (except as part of
such underwritten registration), unless the underwriters managing the registered
public offering otherwise agree.

                 (b) HAGLER  BAILLY  agrees (i) not to effect any public sale or
distribution of its equity  securities,  or any securities  convertible  into or
exchangeable or exercisable for such securities,  during the seven days prior to
and during the 90-day period beginning on the effective date of any underwritten
Piggyback  Registration  (except as part of such  underwritten  registration  or
pursuant to registrations on Form S-8 or Form S-4 or any successor form), unless
the underwriters  managing the registered  public offering  otherwise agree, and
(ii) to use all reasonable  efforts to cause each Person that, during the 30-day
period prior to the effective date of such Piggyback Registration,  holds shares
of HAGLER BAILLY Common Stock (or securities  convertible into or exercisable or
exchangeable  for HAGLER BAILLY Common Stock)  received from HAGLER BAILLY in an
amount which, on a fully diluted basis, exceeds 1% of HAGLER BAILLY Common Stock
then  outstanding (on a fully diluted basis),  to agree not to effect any public
sale  or  distribution  (including  sales  pursuant  to Rule  144)  of any  such
securities during such period (except as part of such underwritten registration,
if otherwise permitted),  unless the underwriters managing the registered public
offering otherwise agree.

                  5.      Tag-Along Rights.

                 If at any time  HAGLER  BAILLY  arranges  for a sale of  HAGLER
BAILLY Common Stock by security holders in a private placement transaction, then
HAGLER  BAILLY  shall  provide  the  FIELDSTON  Stockholders  with  notice and a
reasonable  opportunity to participate in such intended sale on a pro rata basis
with the other selling security holders.

                 6.       Registration Expenses.

                 (a) If  Registerable  Securities are included in a registration
statement for a Piggyback Registration,  then each selling FIELDSTON Stockholder
shall pay all transfer  taxes, if any,  relating to the sale of its shares,  the
fees  and  expenses  of its  own  counsel,  and  its  pro  rata  portion  of any
underwriting discounts or commissions or the equivalent thereof.



                 (b) If  Registerable  Securities are included in a registration
statement  for a Piggyback  Registration,  then except for the fees and expenses
specified  in  Section  6(a)  hereof,  regardless  of whether  any  registration
statement becomes effective,  HAGLER BAILLY shall pay all expenses incident to a
Piggyback  Registration,   including,   without  limitation,  all  registration,
qualification  and filing fees,  fees and expenses of  compliance  with Blue Sky
laws,  underwriting  discounts,  fees,  and expenses  (other than the  FIELDSTON
Stockholders'  pro rata portion of any underwriting  discounts or commissions or
the equivalent thereof, printing expenses,  messenger and delivery expenses, and
fees and  expenses of counsel for HAGLER  BAILLY and all  independent  certified
public accountants and other persons retained by HAGLER BAILLY.

                 7.       Indemnification.

                  (a) HAGLER BAILLY agrees to indemnify, to the extent permitted
by law, each holder of  Registerable  Securities,  each Person who controls such
holder  (within the meaning of Section 15 of the Securities Act or Section 20 of
the Exchange Act) and their respective officers, directors, partners, employees,
agents and representatives, against all losses, claims, damages, liabilities and
expenses  ("Losses')  arising out of or based upon any untrue or alleged  untrue
statement of material fact contained in any registration statement,  prospectus,
or preliminary  prospectus or any amendment thereof or supplement thereto or any
omission or alleged omission of a material fact required to be stated therein or
necessary to make the statements  therein,  in light of the circumstances  under
which they were made,  not  misleading,  except insofar as any such Losses arise
out of or are based upon (i) an untrue  statement or alleged untrue statement or
omission or alleged omission made in any registration statement,  prospectus, or
preliminary  prospectus  or any  amendment  thereof  or  supplement  thereto  in
reliance  upon and in  conformity  with  written  information  furnished by such
holder expressly for use therein or (ii) such holder's failure to deliver a copy
of any  registration  statement or prospectus or any  amendments or  supplements
thereto after HAGLER BAILLY has furnished  such holder with a sufficient  number
of copies of the same,  and except  insofar as any such untrue or alleged untrue
statement of material  fact or such  omission or alleged  omission of a material
fact is caused by or contained in any  prospectus  if such holder failed to send
or deliver a copy of any subsequent  prospectus or prospectus  supplement  which
would have corrected such untrue or alleged untrue statement of material fact or
such  omission  or  alleged  omission  of a  material  fact with or prior to the
delivery of written  confirmation of the sale by such holder after HAGLER BAILLY
has  furnished  such holder with a sufficient  number of copies of the same.  In
connection  with an  underwritten  offering,  HAGLER BAILLY will  indemnify such
underwriters,  each Person who controls such underwriters (within the meaning of
Section 15 of the  Securities  Act or Section 20 of the Exchange  Act) and their
respective officers, directors,  partners, employees, agents and representatives
to the same extent as provided above with respect to the  indemnification of the
holders of Registerable Securities.

                  (b) In  connection  with any  registration  statement in which
holders of  Registerable  Securities  are  participating,  each such holder will
furnish to HAGLER BAILLY in writing such  information  and  affidavits as HAGLER
BAILLY  reasonably  requests for use in  connection  with any such  registration
statement or  prospectus  and, to the extent  permitted by law,  will  indemnify
HAGLER  BAILLY,  each Person who controls  HAGLER BAILLY  (within the meaning of
Section 15 of the  Securities  Act or Section 20 of the Exchange  Act) and their
respective officers, directors,  partners, employees, agents and representatives
against  any Losses  arising  out of or based upon any untrue or alleged  untrue
statement  of  a  material  fact  contained  in  any   registration   statement,
prospectus,  or form of prospectus, or arising out of or based upon any omission
or  alleged  omission  of a  material  fact  required  to be stated  therein  or
necessary to make the statements  therein,  in light of the circumstances  under
which they were made,  not  misleading,  to the extent,  but only to the extent,
that such untrue or alleged  untrue  statement is contained in, or such omission
or alleged omission is required to be contained in, any information so furnished
in  writing  by  such  holder  to  HAGLER  BAILLY  expressly  for  use  in  such
registration  statement or  prospectus  and that such  statement or omission was
relied upon by HAGLER  BAILLY in  preparation  of such  registration  statement,
prospectus  or form of  prospectus;  provided,  however,  that  such  holder  of
Registerable  Securities shall not be liable in any such case to the extent that
the holder has  furnished in writing to HAGLER BAILLY prior to the filing of any
such  registration  statement or prospectus  or amendment or supplement  thereto
information  expressly for use in such  registration  statement or prospectus or
any  amendment or  supplement  thereto  which  corrected or made not  misleading
information  previously  furnished to HAGLER BAILLY, and HAGLER BAILLY failed to
include such information therein. In no event shall the liability of any selling
holder of Registerable Securities hereunder be greater in amount than the dollar
amount of the proceeds (net of payment of all expenses)  received by such holder
upon the sale of the Registerable Securities giving rise to such indemnification
obligation.  Such indemnity shall remain in full force and effect  regardless of
any investigation made by or on behalf of such indemnified party.

                  (c) If any Person  shall be entitled to  indemnity  hereunder,
such  indemnified  party shall give prompt  notice to the party or parties  from
which  such  indemnity  is  sought  of the  commencement  of any  action,  suit,
proceeding  or  investigation  or written  threat  thereof  ("Proceeding")  with
respect to which such indemnified  party seeks  indemnification  or contribution
pursuant  hereto;  provided,   however,  that  the  failure  to  so  notify  the
indemnifying  parties  shall  not  relieve  the  indemnifying  parties  from any
obligation  or liability  hereunder  except to the extent that the  indemnifying
parties have been  prejudiced by such failure.  The  indemnifying  parties shall
have the right,  exercisable by giving  written  notice to an indemnified  party
promptly after the receipt of written notice from such indemnified party of such
Proceeding,  to assume, at the indemnifying parties' expense, the defense of any
such Proceeding, with counsel reasonably satisfactory to such indemnified party;
provided,  however that an  indemnified  party or parties (if more than one such
indemnified  party is named in any  Proceeding)  shall  have the right to employ
separate  counsel  in any such  Proceeding  and to  participate  in the  defense
thereof,  but the fees and expenses of such  counsel  shall be at the expense of
such indemnified party or parties unless the parties to such Proceeding  include
both the indemnified party or parties and the indemnifying party or parties, and
there exists, in the opinion of the parties' counsel,  a conflict between one or
more indemnifying parties and one or more indemnified parties, in which case the
indemnifying  parties  shall,  in  connection  with any one such  Proceeding  or
separate  but  substantially   similar  or  related   Proceedings  in  the  same
jurisdiction,  arising out of the same general allegations or circumstances,  be
liable for the fees and expenses of not more than one separate firm of attorneys
(together with appropriate local counsel) at any time for such indemnified party
or parties. If an indemnifying party assumes the defense of such Proceeding, the
indemnifying  parties will not be subject to any  liability  for any  settlement
made by the indemnified  party without its or their consent (such consent not to
be unreasonably withheld).

                  (d) If the  indemnification  provided for in this Section 7 is
unavailable to an indemnified  party or is insufficient to hold such indemnified
party harmless for any Losses in respect of which this Section 7 would otherwise
apply  by its  terms,  then  each  applicable  indemnifying  party,  in  lieu of
indemnifying such indemnified  party,  shall have a joint and several obligation
to  contribute  to the amount  paid or payable  by such  indemnified  party as a
result of such  Losses,  in such  proportion  as is  appropriate  to reflect the
relative fault of the indemnifying  party, on the one hand, and such indemnified
party,  on the  other  hand,  in  connection  with the  actions,  statements  or
omissions that resulted in such Losses as well as any other  relevant  equitable
considerations.  The relative fault of such indemnifying party, on the one hand,
and indemnified  party, on the other hand,  shall be determined by reference to,
among other  things,  whether any action in  question,  including  any untrue or
alleged untrue  statement of a material fact or omission or alleged  omission to
state a material fact, has been taken by, or relates to information supplied by,
such indemnifying  party or indemnified party, and the parties' relative intent,
knowledge,  access to information and opportunity to correct or prevent any such
action, statement or omission. The amount paid or payable by a party as a result
of any  Losses  shall be deemed to include  any legal or other fees or  expenses
incurred by such party in  connection  with any  Proceeding,  to the extent such
party would have been  indemnified  for such expenses  under Section 7(c) if the
indemnification  provided  for in  Section  7(a) or 7(b) was  available  to such
party.  The  parties  hereto  agree that it would not be just and  equitable  if
contribution  pursuant  to  this  Section  7(d)  were  determined  by  pro  rata
allocation  or by any other method of  allocation  that does not take account of
the equitable considerations referred to in the immediately preceding paragraph.
Notwithstanding  the provision of this Section 7(d), an indemnifying  party that
is a  selling  holder  of  Registerable  Securities  shall  not be  required  to
contribute any amount in excess of the amount by which the net proceeds received
by  such  indemnifying  party  exceeds  the  amount  of any  damages  that  such
indemnifying  party has otherwise been required to pay by reasons of such untrue
or alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent  misrepresentation  (within  the  meaning  of  Section  11(f)  of the
Securities  Act) shall be entitled to  contribution  from any Person who was not
guilty of such fraudulent misrepresentation.

                  8.   Information  by  Holder.   Each  holder  of  Registerable
Securities  shall furnish to HAGLER BAILLY and to the managing  underwriter such
information  regarding such holder and the distribution  proposed by such holder
as HAGLER BAILLY or the managing  underwriter may reasonably  request in writing
and as  shall be  reasonably  required  in  connection  with  any  registration,
qualification or compliance referred to in Section 3.

                  9. Rule 144  Reporting.  With a view to making  available  the
benefits of certain rules and  regulations  of the SEC which may permit the sale
of restricted  securities (as that term is defined in Rule  144(a)(3)  under the
Securities  Act and any  successor  provision  thereto)  to the  public  without
registration, HAGLER BAILLY agrees to:

                  (a) use its  best  efforts  to file  with  the SEC in a timely
manner all  reports and other  documents  required  of HAGLER  BAILLY  under the
Securities Act and the Exchange Act or necessary to satisfy the  requirements of
Rule 144(c) under the Securities Act and any successor provision thereto; and

                  (b) so long as any holder of Registerable  Securities owns any
restricted  securities,  furnish to such holder upon request a written statement
by HAGLER BAILLY as to its  compliance  with the reporting  requirements  of the
Securities  Act and the  Exchange  Act,  a copy of the  most  recent  annual  or
quarterly report of HAGLER BAILLY, and such other reports and documents so filed
as a holder may reasonably  request in availing itself of any rule or regulation
of  the  SEC  allowing  such  holder  to  sell  any  such   securities   without
registration.

assignment,   Affiliates  of  the  FIELDSTON  Stockholders.   If  any  FIELDSTON

         of this Agreement;  provided,  however,  that if all of the Commitments
         are terminated or reduced to zero  hereunder,  the Pro Rata Share shall
         mean, as of any date of determination and with respect to any Lender, a
         fraction  (expressed as a percentage),  the numerator of which shall be
         the sum of the aggregate  amount of such Lender's  Revolving Loans then

ARTICLE II.

GENERAL PROVISIONS OF REVOLVING CREDIT FACILITY

Section 2.01.     The Revolving Loans.

 Revolving  Loan  Borrowings.  Subject  to the  terms  and  conditions  of  this
Agreement,  each Lender severally and not jointly agrees to make revolving loans
(each,  a "Revolving  Loan" and,  collectively,  the  "Revolving  Loans") to the
Borrower,  at any time and from  time to time on and after  the  Effective  Date
until one Business  Day prior to the Maturity  Date in an amount which shall not
exceed such Lender's Pro Rata Share of the Revolving Loan Commitment;  provided,
however,  that (i) the sum of the aggregate  outstanding amount of all Revolving
Loans  plus the  aggregate  outstanding  amount of all Swing Line Loans plus the
aggregate  amount  then  available  to be drawn  under all  outstanding  Standby
Letters of Credit (such sum, the "Total  Outstanding  Amount")  shall at no time
exceed the Maximum Available Amount,  and (ii) the aggregate  outstanding amount
of all Revolving Loans made by each  individual  Lender pursuant to this Section
2.1 plus the aggregate  amount then available to be drawn under all  outstanding
Standby  Letters of Credit  made by or deemed  made by such  Lender  pursuant to
Section 2.3 hereof  shall at no time exceed such  Lender's Pro Rata Share of the
Maximum  Available  Amount.  Within  the  limits  and  subject  to the terms and
conditions set forth in this Agreement, the Borrower may borrow pursuant to this
Section  2.1 and  Section 2.2  hereof,  may prepay  pursuant  to Section  3.6(b)
hereof, and reborrow under this Section 2.1 hereof.

         Section 2.02. The Revolving Notes;  Maturity.  The Revolving Loans made
by each Lender pursuant hereto shall be evidenced by a separate  Revolving Note.
Each  Revolving  Note shall be issued on or before the Effective  Date and shall
bear interest, for the period from the initial Funding Date hereunder until such
Revolving Note shall be paid in full, on the unpaid  principal amount thereof at
the rate  specified  in Section  3.1 of this  Agreement.  Each  Lender is hereby
authorized to record in the books and records of such Lender (without making any
notation in such Lender's Revolving Note or any schedule  thereto),  among other
things,  the amount and Funding Date of each Revolving Loan made by such Lender,
the amount and date of each payment or prepayment of any Revolving  Loan and the
amount and date of any LIBOR Conversion or of any LIBOR Loan converted to an ABR
Loan,  as the case may be. No failure to so record nor any error in so recording
shall affect the  obligations  of the  Borrower to repay the actual  outstanding
principal amount of the Revolving Loans, with interest  thereon,  as provided in
this Agreement.  The aggregate  principal amount of the Revolving Loans shall be
payable on the Maturity Date, unless sooner accelerated pursuant to the terms of
this Agreement.

         Section 2.03.     Revolving Loan Borrowing Procedures.

(a) Notice of  Revolving  Borrowing.  Whenever  the  Borrower  desires to borrow
Revolving  Loans under  Section 2.1 hereof,  the Borrower  shall  deliver to the
Agent  irrevocable  written notice (each such notice,  a "Borrowing  Notice") no
later than 12:00 noon  (Eastern  time) on the Funding Date of a Revolving  Loan;
provided,  however,  that  if any  Revolving  Loan  requested  pursuant  to such
Borrowing Notice is to bear interest based on LIBOR, such Borrowing Notice shall
be delivered no later than 12:00 noon (Eastern  time) on the date (which must be
a Business Day) that is three (3) LIBOR  Business Days prior to the Funding Date
of such Revolving Loan. The Borrowing Notice shall specify (i) that the Borrower
wishes to effect  one or more  Revolving  Loans,  (ii) the  aggregate  principal
amount of each  Revolving Loan thereby  requested  (which shall not be less than
$1,000,000  and shall be in  multiples  of  $250,000  with  respect to each such
Revolving Loan),  (iii) the requested  Funding Date of each such Revolving Loan,
which date shall be a Business  Day (whether or not any  Revolving  Loans are to
bear  interest  based on the ABR or LIBOR),  (iv)  whether  any  Revolving  Loan
requested  pursuant to such Borrowing Notice shall bear interest based on LIBOR,
in which case such Borrowing  Notice shall specify the  applicable  LIBOR Period
being selected by the Borrower (it being understood and agreed that no change in
LIBOR with respect to any then outstanding LIBOR Loan may be effected during the
LIBOR Period  relating  thereto) and (v) the Cash Flow  Multiple then in effect.
Each  Borrowing  Notice  shall  be  accompanied  by  the  officer's  certificate
contemplated   by  Section   4.2(vi)   hereof.   In  lieu  of   delivering   the
above-described  Borrowing Notice, and only with the consent of the Agent in its
sole discretion at such time, the Borrower may give the Agent telephonic  notice
of any such proposed borrowing by the time period, as applicable, required under
this Section  2.2(a);  provided  that, in the event the Agent so consents,  such
notice shall be confirmed in writing by delivery to the Agent  promptly  (but in
no event  later  than  12:00  noon  (Eastern  time) on the  Funding  Date of the
requested  Revolving  Loans) of a Borrowing Notice (it being understood that any
such telephonic  notice shall be irrevocable and shall be conclusive and binding
as against  the  Borrower).  Notwithstanding  anything  contained  herein to the
contrary, if on any Interest Payment Date or Fee Payment Date the credit balance
in the Borrower Account is insufficient to permit the debit  contemplated by the
second  sentence of Section  3.4(a) of this  Agreement,  the Agent,  without any
notice or other authorization  being required,  shall (and is hereby irrevocably
instructed  by the Borrower to) effect  Revolving  Loans (which shall  initially
bear  interest  at the ABR) in an amount  sufficient  to permit such debit to be
implemented or, if the amount of such debit is greater than the aggregate of the
Lender  Availability of all Lenders, in the amount of the unused portion of such
Lender Availability.

(b) Making of Revolving  Loans.  Promptly  after  receipt of a Borrowing  Notice
under  clause  (a) of this  Section  2.2 (or  telephonic  notice if the Agent so
consents  thereto),  the Agent shall  notify each Lender by telecopy or telex or
other customary form of teletransmission of the requested borrowing. Each Lender
shall make the amount of its  Revolving  Loan  available to the Agent in Dollars
and in immediately  available funds, not later than 3:00 P.M.  (Eastern time) on
the Funding Date  applicable  to Revolving  Loan(s)  specified in the  Borrowing
Notice.  After the Agent's  receipt of the proceeds of such Revolving Loans from
the  Lenders,  the Agent  shall  (unless it shall have  learned  that any of the
conditions  precedent  set forth in Section 4.2 hereof have not been  satisfied)
make the  proceeds of such  Revolving  Loans  available  to the Borrower on such
Funding Date  relating  thereto and shall  disburse such funds in Dollars to the
Borrower in immediately available funds by crediting the Borrower Account.

(c) Failure to Fund by Lender.  Unless the Agent shall have been notified by any
Lender  prior to 2:00 P.M.  (Eastern  time) on any  Funding  Date in  respect of
Revolving  Loans  requested  under a Borrowing  Notice that such Lender does not
intend to make  available  to the Agent  such  Lender's  Revolving  Loan on such
Funding  Date,  the  Agent may  assume  that such  Lender  has made such  amount
available to the Agent on such Funding Date and the Agent in its sole discretion
may,  but  shall  not  be  obligated  to,  make  available  to  the  Borrower  a
corresponding  amount on such Funding Date. If such corresponding  amount is not
in fact  made  available  to the  Agent by such  Lender on or prior to 3:00 P.M.
(Eastern  time) on a Funding  Date,  such Lender  agrees to pay and the Borrower
agrees  to repay to the Agent  forthwith  on demand  such  corresponding  amount
together with interest  thereon,  for each day from the date such amount is made
available  to the  Borrower  until the date such amount is paid or repaid to the
Agent,  at (i) in the case of such Lender,  the Federal Funds Rate,  and (ii) in
the case of the  Borrower,  the ABR, and no such  payment by the Borrower  shall
prejudice any rights which the Company or the Agent may have against such Lender
on  account of such  Lender's  failure to so fund its  Revolving  Loan.  If such
Lender  shall pay to the Agent such  corresponding  amount,  such amount so paid
shall  constitute such Lender's  Revolving Loan, and if both such Lender and the
Borrower shall have paid and repaid,  respectively,  such corresponding  amount,
the Agent shall promptly pay over to the Borrower such  corresponding  amount in
same day  funds,  but the  Borrower  shall  remain  obligated  for all  interest
thereon. Nothing contained in this Section 2.2(c) shall be deemed to relieve any
Lender of its  obligation  hereunder to make its  Revolving  Loan on any Funding
Date.

(d) Maximum Number of LIBOR Loans  Outstanding at Anytime.  No more than six (6)
LIBOR Loans shall be permitted  to be  outstanding  under this  Agreement at any
time. In the event that the Borrower  shall request (i) a Revolving  Loan on any
Funding Date to bear interest  based on LIBOR pursuant to this Section 2.2, (ii)
any LIBOR Conversion  pursuant to a LIBOR Conversion Notice under Section 3.8(a)
hereof or (iii) to  continue  any LIBOR  Loan  pursuant  to a  successive  LIBOR
Conversion  Notice under Section 3.8(c) hereof,  the Agent and the Lenders shall
have no  obligation  to make such  Revolving  Loan based on LIBOR or effect such
LIBOR  Conversion or continue any LIBOR Loan if, after giving effect to any such
transaction,  there shall be outstanding  under this Agreement more than six (6)
LIBOR  Loans,  and the Agent and the  Lenders  shall be  irrevocably  authorized
without  notice to the  Borrower to make such  Revolving  Loan as an ABR Loan or
continue  such ABR Loan as such or convert  such  expiring  LIBOR Loan to an ABR
Loan.

         Section 2.04.     Standby Letters of Credit.

(a)  Generally.  Subject to and in accordance  with the terms and conditions set
forth  herein,  the Borrower may request the Issuing  Lender,  from time to time
during the period  commencing on the Effective  Date and ending 10 Business Days
prior to the  Maturity  Date,  to issue,  and  subject  to the terms  hereof the
Issuing  Lender  shall  issue,  for the account of the Borrower and on behalf of
itself or any Subsidiary thereof, one or more standby letters of credit (each, a
"Standby Letter of Credit") pursuant to the Issuing Lender's customary letter of
credit application.  The aggregate  outstanding amount at any time and from time
to time of all  Standby  Letters  of Credit  shall not  exceed  $5,000,000.  The
Issuing  Lender shall have no obligation  to issue any Standby  Letter of Credit
if, after giving effect to the issuance thereof,  the Total  Outstanding  Amount
shall then exceed the Maximum  Available  Amount (it being  understood  that the
Issuing  Lender shall,  upon request of the Borrower,  issue a Standby Letter of
Credit in an amount that would, after giving effect to the issuance thereof, not
cause the Maximum Available Amount to be exceeded).

(b) Standby Letter of Credit Fees;  Maturity.  The Borrower  shall,  among other
things,  pay to the Issuing  Lender for the benefit of the Lenders,  pro rata, a
quarterly fee (the "L/C Fee"),  payable in arrears on the Fee Payment Date.  The
L/C Fee shall be  computed  by  multiplying  the  Applicable  L/C Margin then in
effect by the daily average of the aggregate  available amount to be drawn under
all Standby Letters of Credit outstanding during the Fiscal Quarter  immediately
preceding  the Fee Payment Date (and shall be  calculated  on the basis of a 360
day year and the actual number of days elapsed).  All Standby  Letters of Credit
issued by the Issuing Lender as contemplated by this Section 2.3 shall expire no
later than the Maturity Date. Notwithstanding that the Issuing Lender shall have
no obligation to issue any Standby Letter of Credit the expiration date of which
shall extend  beyond the Maturity  Date, if the  expiration  date of any Standby
Letter of Credit shall in fact extend beyond the Maturity Date, then on the last
Business Day immediately  preceding the Maturity Date,  there shall be deemed to
have been made  Revolving  Loans in the  aggregate  amount then  available to be
drawn under all  Standby  Letters of Credit the  expiration  date of which shall
occur after the Maturity  Date,  the proceeds of which the Issuing  Lender shall
deposit in a collateral account at the Issuing Lender or an Affiliate thereof in
order to  collateralize  such  outstanding  Standby  Letters  of  Credit,  which
collateral  account  shall bear  interest for the account of the Borrower  based
upon  investment  of the funds as agreed  between  the  Issuing  Lender  and the
Borrower.

(c) Standby Letter of Credit Request  Procedure.  Whenever the Borrower  desires
that a Standby  Letter of Credit be issued on its  behalf or on behalf of any of
its Subsidiaries,  the Borrower shall give the Issuing Lender (with copies to be
sent by the Issuing Lender to the Agent and each other Lender) at least five (5)
Business Days' prior written notice therefor. The execution and delivery of each
request for a Standby  Letter of Credit  shall be deemed to be a  representation
and warranty by the Borrower that such Standby Letter of Credit may be issued in
accordance  with,  and will not violate the  requirements  of, this Section 2.3.
Unless the Issuing  Lender has received  notice from any Lender before it issues
the  respective  Standby  Letter  of Credit  that one or more of the  conditions
specified  in Section 4.2 are not then  satisfied,  or that the issuance of such
Standby Letter of Credit would violate this Section 2.3, then the Issuing Lender
may issue the requested Standby Letter of Credit for the account of the Borrower
in accordance  with the terms of this Agreement and, with respect to any matters
not  specifically  covered by this  Agreement,  in  accordance  with the Issuing
Lender's usual and customary practices as in effect from time to time.

(d)      Letter of Credit Participations.

  Immediately  upon the issuance by the Issuing  Lender of any Standby Letter of
Credit,  the Issuing Lender shall be deemed to have sold and transferred to each
Lender  (other than the Issuing  Lender),  and each such Lender  shall be deemed
irrevocably and  unconditionally to have purchased and received from the Issuing
Lender,  without recourse or warranty,  an undivided interest and participation,
in proportion to such Lender's Pro Rata Share, in such Standby Letter of Credit,
each drawing made  thereunder  and the  obligations  of the Borrower  under this
Agreement with respect thereto, and any collateral therefor.  Upon any change in
a Lender's Pro Rata Share of the Revolving Loan Commitment,  it is hereby agreed
that with respect to all outstanding  Standby Letters of Credit,  there shall be
an automatic adjustment to the participations pursuant to this Section 2.3(d) to
reflect the new Pro Rata Share of the Revolving Loan Commitment of the assigning
and assignee Lenders.

 In determining  whether to pay under any Standby Letter of Credit,  the Issuing
Lender shall have no  obligation  relative to the Lenders  other than to confirm
that any documents  required to be delivered under such Standby Letter of Credit
appear to have been  delivered and that they appear to comply on their face with
the  requirements of such Standby Letter of Credit.  Any action taken or omitted
to be taken by the Issuing Lender under or in connection with any Standby Letter
of Credit,  if taken or omitted in the  absence of gross  negligence  or willful
misconduct,  shall not create for the Issuing Lender any resulting  liability to
any Lender.

 Upon the request of any Lender, the Issuing Lender shall furnish to such Lender
copies of any Standby  Letter of Credit to which the Issuing Lender is party and
such  other  documentation  relating  to such  Standby  Letter  of Credit as may
reasonably be requested by such Lender.

 As between the Borrower on the one hand and the Issuing  Lender and the Lenders
on the other hand, the Borrower  assumes all risks of the acts and omissions of,
or misuse of, the Standby Letters of Credit by the respective  beneficiaries  of
such  Standby  Letters  of  Credit.  Without  limiting  the  generality  of  the
foregoing,  neither the Issuing Lender nor any other Lender shall be responsible
(except  in the case of its gross  negligence  or  willful  misconduct)  for the
following:

                           (A)  the  form,  validity,   sufficiency,   accuracy,

                  or any drawing under such Standby  Letters of Credit,  even if
                  it  should  in  fact  prove  to be in  any  respects  invalid,

                           (B) the  validity or  sufficiency  of any  instrument

                  thereunder or proceeds thereof, in whole or in part, which may

                           (C) failure of the  beneficiary  of any such  Standby
                  Letter of Credit to comply fully with  conditions  required in
                  order to draw upon such Standby  Letter of Credit,  other than
                  material  conditions or instructions  that expressly appear in

                           (G) the misapplication by the beneficiary of any such
                  Standby Letter of Credit of the proceeds of any drawing of any

                           (H) any  consequences  arising from causes beyond the
                  control of the Issuing Lender,  including  without  limitation
                  any acts of governments.

 The obligations of the Lenders to make payments to the Agent for the account of
the  Issuing  Lender  with  respect  to  Standby  Letters  of  Credit  shall  be
irrevocable  and not subject to any  qualification  or exception  whatsoever and
shall be made in  accordance  with the terms and  conditions  of this  Agreement
under all circumstances,  including,  without  limitation,  any of the following
circumstances:

     (A) any lack of validity or  enforceability of this Agreement or any of the
     other Credit Documents;

                           (B) the  existence of any claim,  setoff,  defense or
                  other right which the Borrower or any of its  Subsidiaries may
                  have at any time  against  a  beneficiary  named in a  Standby
                  Letter of Credit,  any  transferee  of any  Standby  Letter of
                  Credit  (or any  Person  for whom any such  transferee  may be
                  acting),  the Agent,  the Issuing Lender,  any Lender,  or any
                  other Person,  whether in connection with this Agreement,  any
                  Standby Letter of Credit, the transactions contemplated herein
                  or any unrelated transactions;

                           (C) any  draft,  certificate  or any  other  document
                  presented under the Standby Letter of Credit shall prove to be
                  forged, fraudulent,  invalid or insufficient in any respect or
                  any  statement  therein shall prove to be untrue or inaccurate
                  in any respect;

     (D) the  surrender or  impairment  of any security for the  performance  or
     observance of any of the terms of any of the Credit Documents;

     (E) the  occurrence of any Event of Default or Potential  Event of Default;
     or

                           (F)  the   termination   of  this  Agreement  or  any
Commitment.

                  (e) Standby  Letter of Credit  Drawings  Constitute  Revolving
Loans.  The Issuing Lender shall promptly notify the Agent,  and the Agent shall
promptly  notify  each  Lender,  in each  case by  telecopy  or  telex  or other
customary form of  teletransmission,  of any drawing under any Standby Letter of
Credit (each drawing, a "Drawing").  Each Drawing shall immediately be deemed to
be and for all purposes of this  Agreement  shall  constitute  a Revolving  Loan
hereunder in the amount of such drawing  (which  Revolving  Loan shall,  for the
avoidance  of doubt,  bear  interest  initially  at the ABR).  Each Lender shall
promptly  and  unconditionally  pay to the Agent for the  account of the Issuing
Lender an amount  equal to such  Lender's Pro Rata Share of such Drawing in same
day funds.  Such payment shall be made to the Agent at the Agent Lending Office.
If the Agent  delivers  such notice to such Lender  prior to 2:00 P.M.  (Eastern
time) on any Business  Day,  such Lender shall make its required  payment on the
same  Business  Day.  If and to the  extent  such  Lender  shall  not have  made
available to the Agent for the account of the Issuing  Lender such  Lender's Pro
Rata  Share of such  Drawing,  such  Lender  agrees  to pay to the Agent for the
account of the Issuing Lender,  promptly upon demand, such amount, together with
interest thereon, for each day from such date until the date such amount is paid
to the Agent for the  account of the Issuing  Lender at the  Federal  Funds Rate
plus 100 basis points.  The failure of any Lender to make available to the Agent
for the  account of the Issuing  Lender its Pro Rata Share of any Drawing  shall
not relieve any other Lender of its  obligation  hereunder to make  available to
the  Agent for the  account  of the  Issuing  Lender  its Pro Rata  Share of any
Drawing on the date so  required;  provided,  however,  that no Lender  shall be
responsible  for the failure of any other Lender to make  available to the Agent
for the account of the Issuing Lender such other Lender's Pro Rata Share of such
Drawing.

         Section 2.05.     Swing Line Loan Subfacility.

                  (a)  Swing  Line   Subfacility.   Subject  to  the  terms  and
conditions hereof,  NationsBank,  N.A., in its individual capacity (as such, the
"Swing Line Lender"),  shall, in its sole and absolute discretion from and after
the Effective Date until one Business Day prior to the Maturity Date, make swing
line loans (each, a "Swing Line Loan" and, collectively, the "Swing Line Loans")
to the Borrower;  provided,  however, that (i) the aggregate principal amount of
all Swing Line Loans shall at no time exceed  $5,000,000.00  (such  amount,  the
"Swing Line Subfacility"),  and (ii) the sum of the aggregate outstanding amount
of all Revolving Loans (whether  bearing interest at the ABR or Applicable LIBOR
Rate)  plus the  aggregate  outstanding  amount of all Swing Line Loans plus the
aggregate  amount  then  available  to be drawn  under all  outstanding  Standby
Letters of Credit shall at no time exceed the Maximum Available Amount.

                  (b) The Swing Line Note;  Maturity.  The Swing Line Loans made
by the Swing Line Lender  pursuant to this  Section 2.4 shall be  evidenced by a
separate  Swing Line Note.  The Swing Line Note shall be issued on or before the
Effective  Date and shall  bear  interest  for the  period  from the date of the
initial  funding  of any  Swing  Line  Loan  until  paid in  full on the  unpaid
principal amount thereof.  The Swing Line Lender is hereby  authorized to record
in its books and records  (without making any notation on the Swing Line Note or
any  schedule  thereto)  the  amount and date of funding of each Swing Line Loan
made by it, and the amount and date of each payment or  prepayment  of any Swing
Line Loan.  No failure to so record nor any error in so  recording  shall affect
the obligations of the Borrower to repay the actual outstanding principal amount
of the Swing Line Loans, with interest  thereon,  as provided in this Agreement.
The aggregate  principal  amount of the Swing Line Loans shall be payable on the
Maturity  Date,  unless  sooner  accelerated  pursuant  to  the  terms  of  this
Agreement.

                  (c) Swing Line Loan Borrowing Procedure. The Swing Line Lender
shall make Swing Line Loans to the  Borrower  upon the terms and  subject to the
conditions  contained in the autoborrow  services  agreement entered into by the
Borrower and the Swing Line Lender (as such  agreement may be amended,  modified
or supplemented  from time to time, the "Autoborrow  Services  Agreement"),  and
otherwise  on the date (which shall be a Business  Day),  at the time and in the
amount as provided in the Autoborrow Services Agreement. The Autoborrow Services
Agreement shall specify,  among other things,  the base interest rate applicable
to any Swing Line Loan (such  rate,  the "Base  Swing Line  Rate"),  the minimum
amount of each Swing Line Loan and the minimum and maximum  period  during which
any Swing Line Loan may remain outstanding.  The Swing Line Lender shall have no
obligation to make available to the Borrower any Swing Line Loan until such time
as the Borrower and the Swing Line Lender shall have  executed and delivered the
Autoborrow Services Agreement.

                  (d) Interest on Swing Line Loans. Subject to the provisions of
clause (e) of this  Section  2.4, in the event that the Swing Line Lender  shall
make any Swing Line Loan  pursuant to this Section 2.4 the  aggregate  principal
amount of Swing Line Loans  outstanding from time to time shall bear interest at
a rate per annum  equal to the  Applicable  Swing Line Rate  (based on a 360 day
year and the actual  number of days  elapsed  for the period  during  which such
Swing Line Loan shall remain  outstanding).  No Swing Line Loan may be converted
into a LIBOR Loan.

                  (e)  Repayment of Swing Line Loans.  Each Swing Line Loan made
by the Swing Line Lender  hereunder shall be due and payable upon the expiration
of the period for which  such Swing Line Loan shall be made in  accordance  with
the terms of the Autoborrow  Services  Agreement.  The Swing Line Lender may, at
any time and in its sole and  absolute  discretion,  by  written  notice  to the
Borrower and the Agent (which shall promptly deliver a copy thereof to the other
Lenders),  demand  repayment of its Swing Line Loans then  outstanding by way of
the making of a Revolving  Loan  borrowing (a "Mandatory  Borrowing"),  in which
case the Borrower  shall be deemed to have  requested a Revolving Loan borrowing
in the amount of the then outstanding Swing Line Loans which shall bear interest
initially at the ABR and shall be applied to refund the then  outstanding  Swing
Line Loans; provided,  however, that, in the following  circumstances,  any such
demand shall also be deemed to have been given one Business Day prior to each of
(i) the  occurrence of the Maturity  Date,  (ii) the  occurrence of any Event of
Default  described  in clause  (g) or (h) of  Section  7.1  hereof,  (iii)  upon
acceleration  of the  Obligations  hereunder,  whether on account of an Event of
Default  described  in clause  (g) or (h) of Section  7.1 or any other  Event of
Default,  and (iv) the exercise of remedies in accordance with the provisions of
Section 7.1 hereof. Each Lender hereby irrevocably agrees to make such Revolving
Loans promptly upon any such request or deemed request on account of a Mandatory
Borrowing, in the amount (but in proportion to each Lender's Pro Rata Share) and
in the manner  specified  in the  preceding  sentence  and on the same such date
notwithstanding  that (A) the amount of the  Mandatory  Borrowing may not comply
with the minimum amount for  borrowings of Revolving  Loans  otherwise  required
hereunder,  (B)  whether  any  conditions  specified  in  Section  4.2 are  then
satisfied,  (C) whether an Event of Default or  Potential  Event of Default then
exists, (D) failure of any such request or deemed request for Revolving Loans to
be made by the time  otherwise  required in Section 2.2 hereof,  (E) the date of
such Mandatory Borrowing,  or (F) any reduction in the Revolving Loan Commitment
or termination of the Commitments  relating  thereto  immediately  prior to such
Mandatory  Borrowing  or  contemporaneously  therewith.  In the  event  that any
Mandatory Borrowing cannot for any reason be made on the date otherwise required
above  (including,  without  limitation,  as a result of the  commencement  of a
proceeding in bankruptcy with respect to the Borrower),  then each Lender hereby
agrees that it shall forthwith purchase (as of the date the Mandatory  Borrowing
would otherwise have occurred,  but adjusted for any payments  received from the
Borrower on or after such date and prior to such  purchase)  from the Swing Line
Lender such  participations in the then outstanding Swing Line Loans as shall be
necessary  to cause each such  Lender to share in such Swing Line Loans  ratably
based  upon its  respective  Pro Rata  Share of the  Revolving  Loan  Commitment
(determined  before  giving  effect to any  termination  of the  Revolving  Loan
Commitments  pursuant to the last  paragraph of Section 7.1);  provided that (1)
all  interest  payable on the Swing Line Loans  shall be for the  account of the
Swing Line Lender  until the date as of which the  respective  participation  of
each  other  Lender  is  purchased,   and  (2)  at  the  time  any  purchase  of
participations pursuant to this sentence is actually made, the purchasing Lender
shall be  required to pay to the Swing Line  Lender  interest  on the  principal
amount of such  participation  purchased for each day from and including the day
upon  which  the  Mandatory  Borrowing  would  otherwise  have  occurred  to but
excluding the date of payment for such  participation,  at the rate equal to, if
paid within 2 Business Days of the date of the Mandatory Borrowing,  the Federal
Funds Rate, and thereafter at a rate equal to the Applicable Swing Line Rate.

                  (f) Optional  Prepayment  of Swing Line Loans.  Subject to the
provisions of this clause (f), the Borrower may, at its sole option,  prepay the
principal  amount of the Swing  Line Loans in whole or in part (and in an amount
not less than the amount provided in the Autoborrow  Services  Agreement) at any
time and from time to time,  without  premium  or  penalty.  In  respect of each
Optional  Prepayment  of a Swing Line Loan  proposed to be made by the Borrower,
the right of the  Borrower to make such  Optional  Prepayment  is subject to the
Agent's receipt from the Borrower,  no later than 12:00 P.M. on the Business Day
specified  therein as the date on which such Optional  Prepayment is to be made,
of a written  notice  (which shall be  irrevocable  and a copy thereof  shall be
promptly  delivered by the Agent to the Swing Line Lender)  specifying  (i) that
the Borrower  desires to prepay such Swing Line Loan, (ii) the principal  amount
of such Optional Prepayment,  and (iii) the date (which shall be a Business Day)
on which such Optional  Prepayment  will be made.  Any Optional  Prepayment of a
Swing Line Loan,  which has not been converted to a Revolving  Loan, made by the
Borrower as  permitted  hereunder  shall be paid to the Agent for the account of
the Swing Line Lender no later than 12:00 P.M.  (Eastern Time) on the applicable
prepayment date.

ARTICLE III.

                                       INTEREST, FEES AND REPAYMENT

         Section 3.01.     Interest on the Revolving Loans

(a) ABR.  Except as provided  pursuant to clause (b) of this  Section  3.1,  the
aggregate  principal amount of the Revolving Loans outstanding from time to time
shall  bear  interest  at a rate per annum  equal to the ABR  until  the  entire
principal  amount of the Revolving  Loans shall have been repaid.  Any change in
the rate of interest on the Revolving  Loans  resulting from a change in the ABR
shall be effective as of the opening of business on the day on which such change
is effective.

(b) LIBOR Rate.  In the event the Borrower  shall effect a LIBOR  Conversion  in
accordance  with the  provisions  of Section 3.8 of this  Agreement  or obtain a
Revolving Loan that shall bear interest  initially at the Applicable  LIBOR Rate
as provided in Section 2.2(a)  hereof,  the aggregate  principal  amount of each
Revolving Loan that is the subject of such LIBOR Conversion or Borrowing Notice,
as the  case may be,  shall  bear  interest  at a rate  per  annum  equal to the
Applicable LIBOR Rate in respect of such Revolving Loan.

     (c)  Regulatory  Changes.  If,  after  the  date  of  this  Agreement,  any
     Regulatory Change

 shall  subject any Lender to any tax,  duty or other charge with respect to its
obligation  to make or  maintain  any  Revolving  Loan or Swing Line Loan or any
Standby  Letter  of  Credit  or its  Commitment,  or shall  change  the basis of
taxation  of  payments  to such  Lender of the  principal  of or interest on the
Revolving Loans or Swing Line Loans or in respect of any other amounts due under
this  Agreement in respect of its obligation to make any Revolving Loan or Swing
Line Loan or any Standby Letter of Credit or maintain its Commitment or maintain
any  Standby  Letter of Credit  (except  for  changes  in the rate of tax on the
overall net income of such Lender);  or shall impose,  modify or deem applicable
any reserve, assessment,  special deposit, capital adequacy, capital maintenance
or similar  requirement  against assets of, deposits with or for the account of,
or credit  extended  by,  such  Lender or shall  impose on such Lender any other
condition  affecting  (x) the  obligation  of the Lender to make or maintain the
Revolving  Loans or Swing Line Loans or its  Commitment or any Standby Letter of
Credit, or (y) the Revolving Notes or the Swing Line Note; and the result of any
of the foregoing is to increase the cost to such Lender of making or maintaining
any  Revolving  Loan or Swing  Line  Loan or any  Standby  Letter  of  Credit or
maintaining  its  Commitment  or to reduce  the  amount of any sum  received  or
receivable by such Lender  under,  or the rate of return  attributable  to, this
Agreement  or under the  Revolving  Notes or the Swing Line Note or any  Standby
Letter of Credit,  then such Lender shall give written notice to the Borrower if
such  Regulatory  Change shall impose costs in excess of those costs,  or reduce
the  amount  of any  such  sum or rate of  return  below  the  amount  or  rate,
applicable  on the date of this  Agreement,  and the Borrower  shall pay to such
Lender for the account of such Lender,  not later than 30 days following receipt
by the Borrower of such Lender's  notice,  such additional  amount or amounts as
will  compensate  such Lender for such  increase or  reduction as reflected in a
certificate  of such Lender  attached to such notice setting forth the basis for
the amount of said  increase  or  reduction,  as the case may be.  The  Lender's
certificate  attached  to such  notice  shall be  conclusive  and binding on the
Borrower in the absence of manifest error.

         Section 3.02.  Interest after Due Date. In the event the Borrower fails
to make  any  payment  of the  principal  amount  of or  interest  on any of the
Revolving Loans or Swing Line Loans or of the Unused Portion Fee, the L/C Fee or
the  Administrative  Fee or any other amount owing hereunder,  in each case when
due (whether by demand,  acceleration or otherwise),  the Borrower, shall pay to
the Agent for the account of the Lenders interest on such unpaid amount, payable
from time to time on demand,  from the date such amount shall have become due to
the date of payment thereof, accruing on a daily basis, at a per annum rate (the
"Default Rate") equal to the sum of (x) the ABR plus (y) two percent (2%).


         Section 3.03.     Payment and Computations.

(a) Payments. All payments required or permitted to be made to the Agent, to the
Agent for the account of the Lenders,  or to any Lender under this  Agreement or
under any Revolving  Note or the Swing Line Note shall be made in Dollars (i) if
to the Agent, at the Lending Office of the Agent in immediately  available funds
and (ii) if to any Lender,  to it in immediately  available  funds at an account
specified  by such  Lender in  writing  to the  Borrower.  The  Borrower  hereby
irrevocably  instructs  and  authorizes  the Agent to  effect  each  payment  of
interest on the  Revolving  Loans and the Swing Line Loans due on each  Interest
Payment Date, and of each payment of the Unused Portion Fee, the L/C Fee and the
Administrative Fee due on the Fee Payment Date, by debiting the Borrower Account
on such Interest  Payment Date or Fee Payment Date, as the case may be, with the
aggregate amount thereof,  in each case, after giving effect to the crediting to
the Borrower Account of the proceeds of the Revolving Loan, if any, made on such
Interest  Payment Date or Fee Payment  Date,  as the case may be, in  accordance
with Section 2.2(a) of this  Agreement.  The Agent shall provide to the Borrower
an  invoice  showing  the  amount of such  debit and the  manner in which it was
calculated.

(b)  Computations  of Interest.  Interest on the unpaid portion of the Revolving
Loans and the Swing Line Loans, and interest accruing at the Default Rate on any
amount owing  hereunder,  shall each be calculated for the actual number of days
(including  the  first day but  excluding  the last  day)  elapsed  and shall be
computed on the basis of a year of 360 days.

(c) Interest on Loans.  Interest on the Revolving Loans and the Swing Line Loans
shall be payable in arrears on each Interest Payment Date.

(d)      Application of Payments; Apportionment.

                           (i) Apportionment of Payments and Prepayments. Unless
                  a Lender shall be in default of its obligations to advance any
                  Revolving Loan or reimburse the Agent as provided herein,  all
                  payments and  prepayments of principal and interest in respect
                  of outstanding Revolving Loans and all payments of fees (other
                  than any  fees  payable  pursuant  to the  Administrative  Fee
                  Letter)  and  all  other  payments  in  respect  of any  other
                  Obligations  (other than with respect to the Swing Line Loans)
                  shall be allocated  among (and paid over as soon as reasonably
                  practicable  after receipt  thereof to) such of the Lenders as
                  are entitled  thereto in  proportion to their  respective  Pro
                  Rata Share.  All payments  and  prepayments  of principal  and
                  interest and other  amounts in respect of the Swing Line Loans
                  that  have not been  converted  to  Revolving  Loans  shall be
                  allocated  to the  Swing  Line  Lender,  and all fees  payable
                  pursuant to the  Administrative  Fee Letter shall be allocated
                  only to the Agent.

                           (ii) Upon the occurrence  and during the  continuance
                  of an Event of  Default,  the Agent  shall,  unless  otherwise
                  specified  by the  Required  Lenders as  provided  in the last
                  paragraph of this clause (ii),  apply all payments  (including
                  the proceeds of any  collateral  obtained upon the exercise by
                  the Agent of any remedy  specified in any Credit  Document) in
                  respect of any Obligations:

                                    (A) first,  to pay  Obligations to the Agent
                           in respect of reimbursement of any costs and expenses
                           (including    reasonable    attorney's    fees    and
                           disbursements) in connection with the exercise of any
                           remedies by the Agent under any Credit Document;

                                    (B)  second,  to pay  interest  on and  then
                           principal of any portion of the Revolving Loans which
                           the Agent may have  advanced  on behalf of any Lender
                           for which the Agent has not then been  reimbursed  by
                           such Lender or the Borrower;

                                    (C) third,  to pay Obligations in respect of
                           any fees, expense reimbursement or indemnities due to
                           the Agent  other than as provided  in  subclause  (A)
                           above;

                                    (D) fourth, to pay Obligations in respect of
                           any   fees,   expense   reimbursement,   indemnities,
                           increased  costs or breakage then due to the Lenders,
                           pro rata;

                           interest  due in respect of the  Revolving  Loans and

     (H) eighth, to the ratable payment of all other Obligations;

provided, however, that no Lender that shall be in default of its obligations to

to its  ratable  share of payments  in respect of any  Obligations  prior to the
payment  to all  non-defaulting  Lenders  of all  amounts  due such  Lenders  as
provided herein.

                  The order of priority set forth in this Section  3.4(d)(ii) is
set forth solely to  determine  the rights and  priorities  of the Agent and the
Lenders as among  themselves.  The order of  priority  set forth in clauses  (D)
through (H) of this Section  3.4(d)(ii) may at any time and from time to time be
changed by the Required Lenders without  necessity of notice to or consent of or
approval by the Borrower,  or any other Person.  The order of priority set forth
in clauses (A) through (C) of this Section  3.4(d)(ii)  may be changed only with
the prior written consent of the Agent.

         Section 3.04. Payment at Maturity.  Any outstanding principal amount of
the Revolving  Notes and the Swing Line Note  theretofore  not repaid,  together
with any accrued and unpaid Unused Portion Fee,  Administrative  Fee or L/C Fee,
any accrued and unpaid interest thereon, together with any other amounts due and
payable in accordance with the provisions hereof (including  pursuant to Section
9.10  hereof),  shall be due and payable in full on the  Maturity  Date  (unless
sooner accelerated  pursuant to the terms hereof),  and this Agreement shall not
terminate until all Obligations shall have been paid in full.

         Section 3.05.     Prepayments; Certain Early Repayments.

(a)  Mandatory  Prepayment  of  Revolving  Loans,  Swing Line Loans and  Standby
Letters of Credit. If at any time the Total Outstanding  Amount shall be greater
than the Maximum Available Amount,  the Borrower shall,  without notice from the
Lender,  prepay that portion of the Revolving Loans, Swing Line Loans and/or the
Standby  Letters  of  Credit,  as the case may be,  in an  amount  equal to such
excess.

(b) Optional Prepayments of Revolving Loans. Subject to the terms and conditions
of clause (c) below and Section 3.9 hereof, the Borrower may, at its sole option
prepay the principal  amount of the Revolving Loans (whether bearing interest at
the ABR or  Applicable  LIBOR  Rate)  in  whole  or in  part  (in an  amount  of
$1,000,000  or more and in  multiples  of $250,000) at any time and from time to
time, without premium or penalty.

(c) Optional  Prepayment  Procedure.  In respect of each Optional  Prepayment of
Revolving Loans (whether  bearing  interest at the ABR or Applicable LIBOR Rate)
proposed  to be made by the  Borrower,  the right of the  Borrower  to make such
Optional  Prepayment  is subject to the Agent's  receipt from the  Borrower,  no
later than 10:00 A.M.  (Eastern  Time) on the Business Day specified  therein as
the date on which such  Optional  Prepayment is to be made (unless such Optional
Prepayment  shall relate to the prepayment of any LIBOR Loan, in which case such
notice shall be given no later than 10:00 A.M. (Eastern time) at least three (3)
Business Days prior to the date of prepayment), of a written notice (which shall
be irrevocable) specifying (i) that the Borrower desires to prepay the Revolving
Loans,  (ii) the  principal  amount of such Optional  Prepayment  and the extent
which any portion  thereof  relates the  prepayment of any LIBOR Loan, and (iii)
the date (which shall be a Business Day or, if such Optional  Prepayment relates
to a LIBOR Loan, a LIBOR Business Day) on which such Optional Prepayment will be
made.  Any  Optional  Prepayment  of  Revolving  Loans made by the  Borrower  as
permitted hereunder shall be paid to the Agent for the account of the Lenders no
later than 12:00 P.M.  (Eastern Time) on the applicable  prepayment date (except
that any  prepayment  of a LIBOR  Loan  shall be paid no later  than  10:00 A.M.
(Eastern Time) on the applicable prepayment date).

         Section 3.06.     Unused Portion Fee and Administrative Fee.

(a) Unused  Portion Fee. For each Fiscal  Quarter (or part  thereof)  during the
period from the Effective  Date until the Maturity  Date, the Borrower shall pay
to the Agent,  for the account of the Lenders pro rata based upon each  Lender's
Pro Rata Share of the  Revolving  Loan  Commitment,  an unused  portion fee (the
"Unused  Portion Fee")  determined by subtracting the Total  Outstanding  Amount
(computed on the basis of the daily  average for such Fiscal  Quarter)  from the
Revolving Loan Commitment  Amount. The Unused Portion Fee shall be computed at a
rate per annum equal to, in the event the Funded Debt to EBITDA ratio calculated
pursuant  to Section  6.1(e)  hereof is (i) less than 0.50 to 1.00,  then 0.19%,
(ii) greater than or equal to 0.50 but less than 1.50 to 1.00, then 0.22%, (iii)
greater  than or equal to 1.50 to 1.00 but less than 2.50 to 1.00,  then  0.25%,
and (iv) greater than or equal to 2.50 to 1.00,  then 0.25%.  The Unused Portion
Fee shall be due and  payable in arrears on the Fee  Payment  Date to which such
Unused  Portion Fee relates and on the Maturity Date, and shall be calculated on
the basis of a 360 day year and the actual days elapsed.  The Unused Portion Fee
for any Fiscal  Quarter  shall be determined  based on the financial  statements
delivered by the  Borrower  during the  immediately  preceding  Fiscal  Quarter;
provided, however, that if such financial statements are not delivered when due,
then the highest Funded Debt to EBITDA ratio shall apply.

(b)  Administrative  Fee. During the term of this Agreement,  the Borrower shall
pay to the Agent, as compensation for the services of the Agent hereunder, a fee
(the  "Administrative  Fee") in an amount specified in, and subject to the terms
and  conditions  of, that certain letter  agreement,  dated the Effective  Date,
between  the  Borrower  and the  Agent  (as the same  may  from  time to time be
amended,  modified  or  supplemented,  the  "Administrative  Fee  Letter").  The
Administrative  Fee  shall be due and  payable  on each  Fee  Payment  Date,  as
provided in the Administrative Fee Letter.

         Section 3.07.     LIBOR Conversion.

(a)  Conversion.  So long as no Event of Default or  Potential  Event of Default
shall have  occurred and be  continuing,  the  Borrower  shall have the right to
convert all or part of the  outstanding  ABR Loans to loans bearing  interest at
the  then  Applicable  LIBOR  Rate  (such  conversion,  a  "LIBOR  Conversion");
provided,  however,  that the LIBOR Period to which such LIBOR  Conversion shall
relate  will not extend  beyond the  Maturity  Date.  In order to effect a LIBOR
Conversion,  the Borrower shall give the Agent irrevocable  written notice (such
notice, a "LIBOR  Conversion  Notice") prior to 10:00 A.M. (Eastern time) on the
date  (which must be a Business  Day) that is at least three (3) LIBOR  Business
Days prior to the first day of the LIBOR  Period to which such LIBOR  Conversion
shall apply,  stating that (i) the Borrower wishes to effect a LIBOR Conversion,
(ii) the aggregate  principal amount of outstanding ABR Loans which the Borrower
wishes to bear interest at the  Applicable  LIBOR Rate (it being  understood and
agreed  that no LIBOR  Conversion  shall be  permitted  in an  amount  less than
$1,000,000.00  and shall be in multiples of  $250,000.00),  (iii) the applicable
LIBOR Period being elected by the Borrower (it being  understood  that no change
in LIBOR with respect to any then outstanding  LIBOR Loan may be effected during
the LIBOR Period relating  thereto) and (iv) the Business Day on which the LIBOR
Period is to be effective.

(b) Notice of LIBOR to Borrower. In the event the Borrower has requested a LIBOR
Conversion,  the Agent shall give written notice to the Borrower and the Lenders
of LIBOR as promptly as reasonably  possible after such rate is determined.  The
Agent's  determination  of LIBOR shall be  conclusive in the absence of manifest
error.

(c) Successive Notice of LIBOR  Conversion.  Subject to the provisions of clause
(a) of this  Section 3.8,  the  Borrower  may, by  executing a LIBOR  Conversion
Notice at least  three LIBOR  Business  Days prior to the first day of the LIBOR
Period to which such LIBOR  Conversion  Notice shall apply,  execute  successive
LIBOR  Conversions  with respect to any then  outstanding ABR Loan together with
any then  outstanding  LIBOR  Loans the  LIBOR  Period  in  respect  of which is
scheduled to expire on or before the start of the LIBOR Period specified in such
LIBOR  Conversion  Notice.  If, with respect to any LIBOR Loans, the Agent shall
not have received a LIBOR Conversion Notice for the next immediately  succeeding
LIBOR Period which  complies  with the  provisions of clause (a) of this Section
3.8, such LIBOR Loans shall, immediately upon the expiration of the then current
LIBOR Period and without any notice to the Borrower, bear interest at the ABR in
accordance with the provisions of Section 3.1(a) of this Agreement.

         Section  3.08.  Breakage,  etc. In the event of the  prepayment  of any
LIBOR Loan  (whether by way of  acceleration  or otherwise or due to an Optional
Prepayment of any LIBOR Loan pursuant to Section  3.6(b)  hereof),  the Borrower
shall  pay to each  Lender  whose  LIBOR  Loan has been so  prepaid  any loss or
expense  which such  Lender may incur or  sustain  directly  as a result of such
prepayment,  including,  without limitation, an amount equal to (i) an amount of
interest  which  would have  accrued  on the  amount so  prepaid  for the period
beginning  on the  date of such  prepayment  and  ending  on the last day of the
applicable LIBOR Period (such period, the "Breakage Period"),  at the Applicable
LIBOR Rate minus (ii) the amount of interest (as  reasonably  determined by each
affected  Lender)  which  would have  accrued to such  Lender on such  amount by
placing such amount on deposit for the Breakage Period with leading banks in the
London interbank market.  All amounts owing to a Lender pursuant to this Section
3.9 shall be paid by the Borrower promptly upon written request therefor.

         Section 3.09.  Inability to Determine Interest Rate for LIBOR Loans. In
the event that the Agent shall have  determined  (which  determination  shall be
conclusive  and binding upon the Borrower)  that (a) by reason of  circumstances
affecting the London interbank market  generally,  adequate and reasonable means
do not exist for ascertaining LIBOR for any LIBOR Period with respect to (i) any
proposed Revolving Loan that the Borrower has requested be made as a LIBOR Loan,
(ii) any LIBOR Loans that will result from the  requested  conversion  of all or
part of any ABR Loans into LIBOR Loans,  or (iii) the  continuation of any LIBOR
Loan as such for an  additional  LIBOR  Period,  (b) LIBOR  determined  or to be
determined  for any LIBOR Period will not adequately and fairly reflect the cost
to the Lenders of making or  maintaining  their affected LIBOR Loans during such
LIBOR Period by reason of  circumstances  affecting the London  interbank market
generally  or (c) dollar  deposits in the  relevant  amount and for the relevant
period with respect to any such LIBOR Loan are not available to the Agent in the
London interbank  market,  then the Agent shall,  prior to the requested Funding
Date or the conversion date or the last day of the then applicable LIBOR Period,
as the case may be, notify the Borrower (by telephone or otherwise, confirmed in
writing), with a copy to the Lenders, of such determination.  If the Agent shall
have given such notice,  then (x) any requested LIBOR Loans shall be made as ABR
Loans,  (y) any ABR Loans that were to have been  converted to LIBOR Loans shall
be  continued  as ABR  Loans,  and (z) any  outstanding  LIBOR  Loans  shall  be
converted,  on the last day of the then current LIBOR Period applicable thereto,
into ABR Loans.  Until such notice has been  withdrawn by the Agent,  no further
LIBOR Loans shall be made and no ABR Loans shall be converted to LIBOR Loans.

         Letter of Credit,  the Agent  shall have  received a  Borrowing  Notice
         (except as otherwise provided in the last sentence of Section 2.2(a) of

         the Borrower  designated by such Authorized Officer as having authority
         to execute such notice);

                  (ii)  Payment of  Obligations.  The prospect of payment of all
         obligations and liabilities  outstanding or to become outstanding under

         there shall have been no material  adverse change in the Borrower's and
         the  Guarantors'  (taken  as a  whole)  financial  condition  or in the
         Borrower's and the Guarantors'  (taken as a whole) assets or prospects,
         in each  case as  determined  by the  Required  Lenders  in their  sole
         discretion;

                  (iv)  Representations and Warranties.  The representations and
         warranties  of each Credit Party in the Credit  Documents  are true and
         correct as of such Funding Date (or, in the case of Standby  Letters of
         Credit,  the date of issuance thereof) as though made on and as of such
         Funding Date (or, in the case of Standby Letters of Credit, the date of
         issuance  thereof),  except  to the  extent  such  representations  and
         warranties  relate  solely  to an  earlier  date,  in which  case  such
         representations  and  warranties  shall be true and  correct as of such
         earlier date (and, if any such representation and warranty shall not be
         true and correct,  the Borrower  shall describe in writing to the Agent
         the nature of such misrepresentation and warranty);

                  (v)  No  Event  of  Default.  No  event  has  occurred  and is
         continuing, or would result from such Revolving Loan or Swing Line Loan
         after giving  effect to the  application  of the proceeds  therefrom or
         from the issuance of such Standby  Letter of Credit if the  beneficiary
         thereof  were to fully draw upon such  Standby  Letter of Credit on the
         date of  issuance,  which  constitutes  an  Event of  Default  or would
         constitute a Potential Event of Default;

                  (vi) Maximum  Available  Amount.  After  giving  effect to the
         making of such  Revolving  Loan or Swing Line Loan on the Funding  Date
         thereof  or the  issuance  of such  Standby  Letter  of  Credit  on the
         issuance date thereof,  the Total  Outstanding  Amount shall not exceed
         the Maximum Available Amount; and

                  (vii) Officer's Certificate. In the case of any Revolving Loan
         or  Standby  Letter  of  Credit,   the  Agent  shall  have  received  a
         certificate,  addressed to the Lenders, of an Authorized Officer of the
         Borrower,  dated the date of the Borrowing Notice,  certifying that the
         matters contained in clauses (iii),  (iv), (v) and (vi) of this Section
         4.2 are true and correct.

which case the Borrower  shall cause such  Subsidiaries  to take or refrain from

in effect or any Obligation shall remain unpaid:

(a) Audited Annual Financials.  The Borrower shall deliver to the Agent and each

statements  of  financial   condition,   income,   cash  flows  and  changes  in
shareholders' equity),  together with all notes thereto, of the Borrower and its
Consolidated  Subsidiaries  prepared in accordance with GAAP and certified by an

the rights and priorities of the Agent and the Lenders as among themselves.  The
order the  Required  Lenders  without  necessity  of notice to or  consent of or
approval by the  Borrower,  or any other  Person.  The order  acceptable  to the
Agent,  relating to the Borrower and its Consolidated  Subsidiaries as the Agent

Borrower and its  Consolidated  Subsidiaries  shall have not suffered a net loss

of the Borrower to the effect that the information contained therein is true and
accurate as of the date of such  certificate,  that the  Borrower  and the other
Credit Parties are in compliance with all covenants  contained in this Agreement
(including  the  financial  ratios  contained in this Section 6.1) and the other
Credit  Documents and that no Event of Default or Potential Event of Default has
occurred and is continuing hereunder.

(c) Exchange Act and Securities Act Filings.  The Borrower shall deliver to each
Lender and the Agent, within 5 days following the filing with the SEC, copies of
all filings by it or any of its  Subsidiaries  under the Exchange Act (including
reports on Forms 10-Q, 10-K and 8-K) and registration  statements filed with the
SEC under  either the  Securities  Act or the Exchange  Act. The Borrower  shall

Subsidiaries to cooperate with each Lender and shall execute and deliver to such
Lender in a timely manner such forms (including  Internal Revenue Service Forms)
and certificates as such Lender shall reasonably  request,  in each case for the
purpose of confirming  that such Lender is capable,  under the provisions of any
applicable  tax treaty  concluded with the United States of America or any other
applicable law, of receiving payments of interest hereunder without deduction or
withholding  of any tax.  In the event that any such tax shall be required to be
withheld or deducted, the Borrower shall pay to such Lender an amount that would
fully indemnify such Lender for such withheld or deducted amount.

(e) Funded Debt to EBITDA Ratio. The Borrower and its Consolidated Subsidiaries,
taken as a whole,  shall  maintain,  for (and at all times  during)  each Fiscal
Quarter beginning with the Fiscal Quarter ended September 30, 1998 (the "Initial
Fiscal  Quarter"),  a ratio of Funded Debt to EBITDA of not greater than 3.00 to
1.00. The ratio  contemplated  by this clause (e) shall be computed on the basis
of a rolling four quarter period and shall include the results of operations for
the Fiscal Quarter for which such ratio shall be determined plus the immediately
preceding three Fiscal Quarters;  provided, however, that to the extent that any
Acquisition  Party  acquired in accordance  with Section 6.2(e) hereof shall not
constitute a Subsidiary  for a period  falling within such rolling four quarters
at the time of the  determination of this ratio, then EBITDA for the purposes of
this ratio shall include,  for such rolling four quarter period as it relates to
such Acquisition  Party, (i) the pro forma EBITDA of such Acquisition  Party for
that portion of the rolling four quarter  period  during which such  Acquisition
Party was not a Subsidiary of the  Borrower,  and (ii) the actual EBITDA of such
Acquisition  Party for that portion of the rolling four  quarter  period  during
which such Acquisition Party  constitutes a Subsidiary of the Borrower.  For the
purposes  of  illustration  of the  proviso  to the  preceding  sentence,  if an
Acquisition  Party is acquired on March 31, 2000 and the ratio  contemplated  by
this clause (e) shall be determined  for the period  ending June 30, 2000,  then
such Acquisition Party's pro forma EBITDA as it existed prior to the acquisition
for the quarters  ending  September  30,  1999,  December 31, 1999 and March 31,
2000,  together with such  Acquisition  Party's actual EBITDA as a Subsidiary of
the Borrower for the quarter  ending June 30, 2000,  shall be taken into account
for the purposes of calculating this ratio.

(f) No Net Loss.  The Borrower  and its  Consolidated  Subsidiaries,  taken as a
whole,  shall not suffer a net loss  (before  (i)  extraordinary  gains and (ii)
non-cash,   non-recurring  compensatory  charges  incurred  in  connection  with
acquisitions) for any Fiscal Quarter.

(g) Fixed Charge Coverage Ratio. The Borrower and its Consolidated Subsidiaries,
taken as a whole,  shall at all times  maintain,  for (and at all times  during)
each Fiscal  Quarter  beginning  with the  Initial  Fiscal  Quarter,  a ratio of
Consolidated  Cash Flow to  Consolidated  Fixed Charges of not less than 2.00 to
1.00. The ratio  contemplated  by this clause (g) shall be computed on the basis
of a rolling four quarter period and shall include the results of operations for
Fiscal  Quarter for which such ratio shall be  determined  plus the  immediately
preceding three Fiscal Quarters;  provided, however, that to the extent that any
Acquisition  Party  acquired in accordance  with Section 6.2(e) hereof shall not
constitute a Subsidiary  for a period  falling within such rolling four quarters
at the time of the  determination of this ratio, then Consolidated Cash Flow for
the purposes of this ratio shall  include,  for such rolling four quarter period
as it relates  to such  Acquisition  Party,  (i) the pro forma Cash Flow of such
Acquisition  Party for that portion of the rolling four  quarter  period  during
which such Acquisition Party was not a Subsidiary of the Borrower,  and (ii) the
actual Cash Flow of such Acquisition  Party for that portion of the rolling four
quarter period during which such Acquisition  Party  constitutes a Subsidiary of
the Borrower.  For the purposes of  illustration of the proviso to the preceding
sentence,  if an  Acquisition  Party is acquired on March 31, 2000 and the ratio
contemplated  by this clause (g) shall be determined  for the period ending June
30, 2000, then such Acquisition  Party's pro forma Cash Flow as it existed prior
to the acquisition for the quarters ending September 30, 1999, December 31, 1999
and March 31, 2000, together with such Acquisition Party's actual Cash Flow as a
Subsidiary of the Borrower for the quarter ending June 30, 2000,  shall be taken
into account for the purposes of calculating this ratio.

(h) Proceeds.  The Borrower shall use the proceeds of the Revolving  Loans,  the
Swing Line Loans and the Standby  Letters of Credit for the  Permitted  Uses and
for no other purpose.

(i) Payment of Debts and Taxes. The Borrower and its Subsidiaries  shall pay all
debts,  liabilities,  taxes, assessments and other governmental charges when due
in the ordinary course;  provided,  however, that no such debt, liability,  tax,
assessment or other governmental  charge need be paid if such is being contested
in good faith by appropriate legal proceedings promptly initiated and diligently
conducted and if such reserves or other appropriate provision,  if any, as shall
be required by GAAP shall have been made therefor.

(j) Conduct of Business.  The Borrower and its  Subsidiaries  shall  continue to
engage in business of the same general type as now  conducted by the Borrower or
such Subsidiary. The Borrower and its Subsidiaries will conduct and manage their
respective business and affairs in the ordinary course, and shall take all steps
necessary  and  reasonable  for the  purpose  of  preserving  the value of their
respective business and assets.

(k) Preservation of Corporate Existence.  Except as otherwise permitted pursuant
to Section 6.2(e) hereof,  the Borrower and its Subsidiaries  shall at all times
preserve and keep in full force and effect their respective  corporate existence
and their  respective  rights,  privileges,  licenses and  franchises  which are
necessary in the normal conduct of their business.

(l) Books and Records. The Borrower and its Subsidiaries shall at all times keep
and maintain complete and accurate books, accounts and records of its operations
and affairs in accordance with customary and sound business practices, and shall
permit  each  Lender  and the Agent and their  respective  officers,  employees,
agents and  representatives  to,  from time to time upon  reasonable  notice and

and  covering  such risks as is  consistent  with sound  business  practice  for
companies  similarly  situated  and in  the  same  or  similar  businesses.  Any
insurance may be subject to  deductibility  or similar clauses which, in effect,
result in  self-insurance of certain losses,  provided that such  self-insurance
under the insurance referred to above is in accord with the general practices of
companies  similarly  situated and adequate insurance reserves are maintained in
connection  with such  self-insurance.  Any  policies  of  insurance  carried in
accordance  with this Section 6.1(m) and any policies taken out in  substitution

insurance,  name the Agent as  additional  insured (the  "Additional  Insured"),
(iii)  provide  that in the case of any  policies  that  contain any  condition,
warranty  or  declaration  (other than the failure to pay  premiums)  which,  if
breached  or violated  prior to a loss,  would void the  insurance  or allow the
underwriters  to avoid  liability  under the policy,  the  insurance  under such
policies shall not be invalidated, in respect to the respective interests of the
Loss  Payee and the  Additional  Insured  in such  insurance,  by any  action or
inaction of the Borrower or its Subsidiaries,  and shall insure the Loss Payee's
and the Additional Insured's interests, regardless of any breach or violation of
any  warranty,  declaration  or  condition  contained  in such  policies  by the
Borrower or any of its  Subsidiaries,  (iv) provide that,  if such  insurance is
cancelled for any reason  whatsoever,  or any substantial  change is made in the
policy which affects the coverage  certified to the Agent,  or if such insurance
is allowed to lapse for  nonpayment  of premium,  such  cancellation,  change or
lapse shall not be effective as to the Loss Payee and the Additional Insured for
30 days after  receipt by the Agent of written  notice from such insurer of such
cancellation,  change or lapse,  (v) provide that neither the Loss Payee nor the
Additional  Insured  shall  have  any  obligation  or  liability  for  premiums,
commissions,  assessments  or calls in  connection  with  such  insurance,  (vi)
provide that the insurers waive (A) any rights to set-off,  counterclaims or any
other deduction, whether by attachment or otherwise, which they may have against
the Loss Payee or the  Additional  Insured,  and (B) any  rights of  subrogation
against the Loss Payee or any Additional Insured, (vii) be primary without right
of contribution  from any other insurance which may be carried by the Loss Payee
or any Additional Insured,  and (viii) in the case of public liability policies,
provide that all  provisions of such  insurance,  except the limits of liability
(which shall be borne solely by the  Borrower)  shall operate in the same manner
as if there were a separate  policy  covering each named  insured.  The Borrower
will  furnish to the Agent upon  request full  information  as to all  insurance
carried by the Borrower or any Subsidiary.

(n) Compliance  with Laws. The Borrower and its  Subsidiaries  shall comply with
all  applicable  laws,  rules,  regulations  and orders of any  governmental  or

any Foreign  Subsidiary of the  Borrower,  not more than 5% of the capital stock

concerning  the  discharge  of  substances   into  the   environment  and  other
environmental   control  matters  or  (ii)  under  which  the  Borrower  or  its
Subsidiaries  shall  admit to any such  violation.  Each copy of any such notice
shall be delivered to the Lenders and the Agent  promptly  following the receipt
or issuance thereof by the Borrower or such Subsidiary.

(s) Seniority.  Under applicable laws in force from time to time, the claims and
rights of the Lenders and the Agent  against  each Credit Party under the Credit
Documents will not be  subordinate  to, and will rank senior in right of payment
to, the claims and rights of each other creditor of each Credit Party.

(t) Year 2000  Compliance.  The Borrower will  promptly  notify the Agent in the
event  the  Borrower  discovers  or  determines  that any  computer  application
(including those of its suppliers and vendors) that is material to its or any of
its  Subsidiaries'  business and operations will not be Year 2000 Compliant on a
timely  basis,  except to the extent that such failure  could not  reasonably be
expected to have a material  adverse effect upon the Borrower or such Subsidiary
taken as a whole.

pledged  to the Agent  sixty-five  percent  (65%) of the  outstanding  shares of

the terms,  conditions,  covenants and  agreements  contained in the  Subsidiary
Guarantee and such  Subsidiary or Affiliate shall have delivered such documents,
certificates and opinions as any Lender may reasonably request to implement such
agreement or instrument;  provided, however, that the Borrower may make advances
to any Foreign  Subsidiary  without such Foreign Subsidiary being a party to the
Subsidiary  Guarantee so long as the  aggregate  amount of all such  advances to
such  Foreign  Subsidiaries,  together  with  all  loans  made to  such  Foreign

any of its assets  (whether real or personal) other than (i) in the ordinary and
usual course of its business for fair value in arm's-length transactions and, so
long as no Event of Default or  Potential  Event of Default has  occurred and is
continuing,  dispositions in a commercially reasonable manner of equipment which
has become redundant,  worn out or obsolete or which should be replaced so as to
improve  productivity,  so long as the proceeds of any such  disposition are (A)
used to acquire replacement equipment which has comparable or better utility and
equivalent or better value or (B) applied to repay the Obligations,  and (ii) as
otherwise permitted by any other Credit Document.

(j)  Permitted  Investments.  Neither the  Borrower nor any  Subsidiary  thereof
shall,  without the prior  written  consent of the  Required  Lenders,  make any

clause  (j)  shall  not  prohibit  the  acquisition  of  the  securities  of any
Acquisition  Party to the extent  permitted by the  provisions of Section 6.2(e)
hereof).

                                                THE AGENT

     Section 8.01.  Appointment of Agent. TC "Section 8.1 Appointment of Agent."
     \f C \l "2"

(a) Appointment  Generally.  Each of the Lenders hereby  designates and appoints
NationsBank, N.A. as the Agent of such Lender under this Agreement and the other
Credit  Documents,  and each of the Lenders  hereby  irrevocably  authorizes the
Agent to take such action on its behalf under the  provisions of this  Agreement
and the other  Credit  Documents  and to  exercise  such powers as are set forth
herein and therein,  together with such other powers as are incidental  thereto.
The Agent  agrees to act as such on the  express  conditions  contained  in this
Article VIII.

(b) Agent Acts for Lenders.  The  provisions of this Article VIII are solely for
the benefit of the Agent and the Lenders,  and the Borrower  shall have no right
(including  as  third  party  beneficiary)  to  rely  on or  enforce  any of the
provisions  hereof.  In  performing  its  functions  and other duties under this
Agreement  and the other Credit  Documents,  the Agent shall act solely as agent
for the Lenders and does not assume and shall not be deemed to have  assumed any
obligation toward or relationship of agency or trust with or for the Borrower or
any of its Affiliates.

     "Section 8.2 Nature of Duties; Non-Reliance on Agent and other Lenders." \f
     C \l "2"

(a) The  Agent  shall  not have any  duties  or  responsibilities  except  those
expressly  set forth in this  Agreement  or in the other Credit  Documents.  The
duties of the Agent shall be mechanical and  administrative in nature. The Agent
shall not have,  by reason of this  Agreement  or any other Credit  Document,  a
fiduciary  relationship  in respect  of any Lender and is not a trustee  for the
Lenders.  Nothing  in  this  Agreement  or any of the  other  Credit  Documents,
expressed  or implied,  is intended to or shall be  construed to impose upon the
Agent any  obligations  in respect of this  Agreement or any of the other Credit
Documents  except as expressly set forth herein and therein.  If the Agent seeks
the consent or approval of the Lenders to the taking or  refraining  from taking
of any action hereunder, the Agent shall send notice thereof to each Lender. The
Agent shall promptly notify each Lender at any time the Required  Lenders or all
of the Lenders,  as the case may be, have instructed the Agent to act or refrain
from acting pursuant  hereto.  The Agent may execute any of its duties hereunder
or under any other Credit Document by or through agents or attorneys-in-fact and
shall be entitled to advice of counsel concerning all matters pertaining to such
duties.  The Agent shall not be responsible  for the negligence or misconduct of
any agents or attorneys-in-fact selected by it with reasonable care.

(b) Each Lender  expressly  acknowledges  that  neither the Agent nor any of its
officers, directors, employees, agents, attorneys-in-fact or Affiliates has made
any  representations  or  warranties  to it and that no act by the  Agent or any
Affiliate thereof hereinafter taken,  including any review of the affairs of the
Borrower  or  any  Subsidiary  thereof,   shall  be  deemed  to  constitute  any
representation or warranty by the Agent to any Lender. Each Lender represents to
the Agent that it has,  independently and without reliance upon the Agent or any
other  Lender,  and based on such  documents  and  information  as it has deemed
appropriate,  made its own  appraisal of and  investigation  into the  business,
assets,  operations,  property,  financial and other  conditions,  prospects and
creditworthiness  of the Borrower and its Subsidiaries and made its own decision
to make its Revolving  Loans and issue or participate in the issuance of Standby
Letters of Credit  hereunder and enter into this  Agreement and the other Credit
Documents  to  which  it  is a  party.  Each  Lender  covenants  that  it  will,
independently and without reliance upon the Agent or any other Lender, and based
on such  documents and  information  as it shall deem  appropriate  at the time,
continue to make its own credit analysis,  appraisals and decisions in taking or
not taking action under this Agreement or any other Credit  Document to which it
is a party,  and to make such  investigations  as it deems  necessary  to inform
itself as to the business,  assets,  operations,  property,  financial and other
conditions, prospects and creditworthiness of the Borrower and its Subsidiaries.
Except  for  notices,  reports  and other  documents  expressly  required  to be
furnished  to the Lenders by the Agent  hereunder,  the Agent shall not have any
duty  or  responsibility  to  provide  any  Lender  with  any  credit  or  other
information concerning the business, operations, assets, property, financial and
other  conditions,  prospects  or  creditworthiness  of  the  Borrower  and  its
Subsidiaries  which  may come  into the  possession  of the  Agent or any of its
officers, directors, employees, agents, attorneys-in-fact or Affiliates.

Section 8.03.  Rights,  Exculpation,  Etc. TC "Section 8.3 Rights,  Exculpation,
Etc." \f C \l "2" Neither the Agent nor any of its  Affiliates  nor any of their
respective  officers,  directors,  employees,  agents,  attorneys or consultants
shall be liable to any  Lender  for any  action  taken or  omitted by it or such
Person  hereunder or under any of the other Credit  Documents,  or in connection
herewith or therewith, except that (i) the Agent shall be obligated on the terms
set forth herein for performance of its express obligations hereunder,  and (ii)
neither the Agent nor any such other Person shall have any  liability  hereunder
or under any other Credit  Document  except to the extent arising out of its own
gross negligence or willful misconduct (as determined by the final judgment of a
court  of  competent  jurisdiction).  The  Agent  shall  not be  liable  for any
apportionment  or  distribution of payments made by it in good faith pursuant to
the terms of this Agreement and if any such  apportionment  or  distribution  is
subsequently  determined  to have been made in error  the sole  recourse  of any
Lender to whom  payment was due,  but not made,  shall be to recover  from other
Lenders any payment in excess of the amount to which they are determined to have
been  entitled.  The  Agent  shall  not be  responsible  to any  Lender  for any
recitals, statements,  representations or warranties made by the Borrower or any
Subsidiary  thereof in this Agreement or in any other Credit  Document or in any
other  document,  certificate,  report or financial  statement  delivered by the
Borrower or any  Subsidiary  thereof in connection  herewith or therewith or for
the   execution,    effectiveness,    genuineness,   validity,   enforceability,
collectibility,  or  sufficiency  of this  Agreement  or any of the other Credit
Documents, or any of the transactions contemplated thereby, or for the financial
condition  of the  Borrower or any of its  Subsidiaries.  The Agent shall not be
required to make any inquiry  concerning  conditions of this Agreement or any of
the  Credit  Documents  or  the  financial  condition  of  the  Borrower  or its
Subsidiaries  or the existence or possible  existence of any Potential  Event of
Default or Event of Default. The Agent may at any time request instructions from
the Lenders with respect to any actions or approvals  which by the terms of this
Agreement  or of any of the other  Credit  Documents  the Agent is  permitted or
required to take or to grant, and if such  instructions are promptly  requested,
the Agent shall be  absolutely  entitled to refrain from taking any action or to
withhold any approval and shall not incur any liability whatsoever to any Person
for  refraining  from any action or  withholding  any approval  under any of the
Credit  Documents  until it  shall  have  received  such  instructions  from the
Required Lenders or, to the extent specifically provided herein, all the Lenders
or unless it shall  first be  indemnified  by the  Lenders  against  any and all
liability  and expense  which may be incurred by it by reason of  refraining  to
take any action or withholding any approval.  Without limiting the foregoing, no
Lender shall have any right of action  whatsoever  against the Agent as a result
of the Agent acting or refraining from acting under this Agreement or any of the
other  Credit  Documents in  accordance  with the  instructions  of the Required
Lenders or, to the extent  specifically  provided herein,  all the Lenders,  and
such instructions  shall be binding upon all Lenders (including their successors
and assigns).

     Section 8.04. Reliance; Notice of Default. TC "Section 8.4 Reliance; Notice
     of Default." \f C \l "2"

(a) The Agent  shall be entitled  to rely upon any  written  notice,  statement,
certificate,  order, letter,  cablegram,  telegram,  telecopy, telex or teletype
message,  statement or other document or any telephone message believed by it in
good  faith to be genuine  and  correct  and to have been  signed or made by the
proper Person,  and with respect to all matters  pertaining to this Agreement or
any of the other Credit Documents and its duties  hereunder or thereunder,  upon
advice of legal counsel  (including  counsel for any Credit Party),  independent
public  accountants and other experts  selected by it with reasonable  care. The
Agent may deem and treat each Lender as the owner of its interests hereunder for
all  purposes  unless and until the Agent  shall have  received a duly  executed
instrument of assignment as  contemplated by Section 9.8(c) hereof and the other
conditions to assignment, to the extent applicable, shall have been satisfied.

(b) The Agent shall not be deemed to have  knowledge or notice of the occurrence
of any Event of  Default  or  Potential  Event of  Default  unless the Agent has
received  notice  from a Lender or the  Borrower  referring  to this  Agreement,
describing  such Event of Default or Potential Event of Default and stating that
such notice is a "notice of Event of Default" of "notice of  Potential  Event of
Default",  as the case may be. The Agent shall take such action with  respect to
such  Event of  Default or  Potential  Event of  Default as shall be  reasonably
directed by the Required Lenders.

Section 8.05. Indemnification.  TC "Section 8.5 Indemnification." \f C \l "2" To
the extent that the Agent is not reimbursed  and  indemnified by the Borrower or
the  Borrower  fails upon  demand by the Agent to  perform  its  obligations  to
reimburse  or indemnify  the Agent,  the Lenders will  severally  reimburse  and
indemnify  the  Agent  for and  against  any and all  liabilities,  obligations,
losses,  damages,  penalties,  actions,  judgments,  suits,  costs,  expenses or
disbursements of any kind or nature whatsoever which may be imposed on, incurred
by, or asserted  against the Agent in any way relating to or arising out of this
Agreement or any of the other Credit Documents or any action taken or omitted by
the  Agent  under  this  Agreement  or any of the  other  Credit  Documents,  in
proportion  to each Lender's Pro Rata Share;  provided,  that no Lender shall be
liable for (i) any portion of such liabilities,  obligations,  losses,  damages,
penalties, actions, judgments, suits, costs, expenses or disbursements resulting
from the Agent's gross  negligence or willful  misconduct  (as determined by the
final judgment of a court of competent  jurisdiction) or (ii) the legal fees and
expenses  incurred by the Agent in connection with the execution and delivery of
this  Agreement and the other Credit  Documents (to the extent not reimbursed by
the  Borrower).  The  obligations  of the Lenders  under this  Section 8.5 shall
survive the payment in full of the Revolving  Loans and the  termination of this
Agreement.

Section 8.06. The Agent Individually.  TC "Section 8.6 The Agent  Individually."
\f C \l "2" With  respect  to its Pro Rata  Share  hereunder  and the  Revolving
Loans,  Standby  Letters of Credit and any Swing Line Loan made by it, the Agent
shall have and may exercise the same rights and powers  hereunder and is subject
to the same  obligations  and  liabilities as and to the extent set forth herein
for any other Lender.  The term  "Lenders" or "Required  Lenders" or any similar
terms shall, unless the context clearly otherwise  indicates,  include the Agent
in its individual  capacity as a Lender. The Agent and its Affiliates may accept
deposits from, lend money to, and generally engage in any kind of banking, trust
or other  business  with the  Borrower  and its  Subsidiaries  as if it were not
acting as Agent pursuant hereto.

     Successor Agent; Resignation of Agent." \f C \l "2"

(a) The Agent may  resign  from the  performance  of its  functions  and  duties
hereunder at any time by giving at least thirty (30) days' prior written  notice
to the Lenders and the Borrower. In the event that the Agent gives notice of its
desire to resign from the performance of its functions and duties as Agent,  any
such resignation shall take effect only upon the acceptance by a successor Agent
of appointment pursuant to clause (b) or (c) below.

(b) The Required Lenders shall jointly appoint a successor Agent, which shall be
a Lender hereunder.

(c) If a  successor  Agent shall not have been so  appointed  within said twenty
(20) day period,  the retiring  Agent shall then  appoint a successor  Agent who
shall serve as Agent until such time, if any, as the Lenders appoint a successor
Agent as provided above, it being understood and agreed that any successor Agent
so  appointed  by the  retiring  Agent  pursuant to this clause (c) need not be,
notwithstanding  the provisions of clause (b) above, a Lender  hereunder so long
as such successor  Agent is a commercial  bank  organized  under the laws of the

                                               SUBSIDIARY GUARANTEE


         SUBSIDIARY GUARANTEE, dated as of November 20, 1998 (this "Guarantee"),
is made by each of the entities that are signatories  hereto (the  "Guarantors")
in favor of NATIONSBANK,  N.A., as Agent (in such capacity, the "Agent") for the
lenders and other financial  institutions  (the "Lenders") that are from time to
time parties to the Revolving Credit Agreement described below.

                                               W I T N E S S E T H:

         WHEREAS,  HAGLER BAILLY,  INC., a Delaware corporation (the "Company"),
is party to the Revolving Credit Agreement, dated as of November 20, 1998, among
the Company,  the Lenders and the Agent (as amended,  supplemented  or otherwise
modified from time to time, the "Revolving Credit Agreement");

         WHEREAS,  pursuant to the terms of the Revolving  Credit  Agreement and
the other Credit Documents, the Lenders have severally agreed to make extensions
of credit in the form of Revolving  Loans,  Swing Line Loans and Standby Letters
of Credit to or for the benefit of the Company;

         WHEREAS,  except as set forth in the Revolving  Credit Agreement or the
schedules attached thereto, the Company owns, directly or indirectly, all of the
issued and outstanding  shares of capital of stock of, or other equity interests
in, each of the Guarantors;

         WHEREAS,  the proceeds of such  Revolving  Loans,  Swing Line Loans and
Standby  Letters of Credit may be used to enable  the  Company to make  valuable
transfers to any or all of the  Guarantors in  connection  with the operation of
their respective businesses and for the Permitted Uses;

         WHEREAS,  each  Guarantor will derive  substantial  direct and indirect
benefit  from such  Revolving  Loans,  Swing Line Loans and  Standby  Letters of
Credit; and

         WHEREAS,  the  obligation of the Lenders to make the  Revolving  Loans,
Swing Line Loans and issue the Standby  Letters of Credit is  conditioned  upon,
among other things,  the  execution and delivery by each of the  Guarantors of a
guarantee to the Agent for the benefit of the Agent and for the ratable  benefit
of the Lenders;

         NOW,  THEREFORE,  in  consideration  of the  premises,  the  commercial
benefits  accruing to each Guarantor and to induce the Lenders to enter into the
Revolving  Credit  Agreement and to make the Revolving  Loans and the Swing Line
Loans and to issue the Standby Letters of Credit,  each Guarantor  hereby agrees
with and for the benefit of the Agent and the Lenders as follows:

         SECTION 1. Defined Terms. As used in this  Guarantee,  terms defined in
the Revolving Credit Agreement (unless otherwise defined herein) are used herein
as therein  defined,  and the following terms shall have the following  meanings
(such meanings to be, when appropriate,  equally applicable to both the singular
and plural forms of the terms defined):

"Agent" shall have the meaning specified in the preamble hereof.

"Guarantee" shall have the meaning specified in the preamble hereof.

"Guarantors" shall have the meaning specified in the preamble hereof.

"Lenders" shall have the meaning specified in the preamble hereof.

"Maximum Guaranteed Amount" for any Guarantor shall mean the amount which can be
guaranteed by such Guarantor under applicable federal and state laws relating to
the insolvency of debtors.

     "Revolving  Credit Agreement" shall have the meaning specified in the first
     whereas clause hereof.

                  SECTION 2.   Guarantee.

(a)  Each  of  the  Guarantors  hereby,   jointly  and  severally,   absolutely,
unconditionally  and  irrevocably  guarantees  to the Agent and the  Lenders and
their respective successors,  indorsees,  transferees and assigns the prompt and
complete  payment by the Company  when due (whether at the stated  maturity,  by
acceleration or otherwise) of the Obligations, and each Guarantor further agrees
to pay any and all expenses (including,  without limitation, all reasonable fees
and  disbursements of counsel) which may be paid or incurred by the Agent or any
Lender in  enforcing,  or obtaining  advice of counsel in respect of, any rights
with respect to, or collecting,  any or all of the Obligations  and/or enforcing
any rights with respect to, or collecting  against,  such  Guarantor  under this
Guarantee;  provided,  however, that,  notwithstanding  anything to the contrary
contained herein or in any other Credit Document,  the maximum liability of each
Guarantor  hereunder  and  under the other  Credit  Documents  shall in no event
exceed such Guarantor's Maximum Guaranteed Amount. This Guarantee  constitutes a
present and continuing  guarantee of payment and performance when due and not of
collection,  and  each of the  Guarantors,  as a  primary  obligor  and not as a
surety,  specifically agrees that no Guarantor shall be entitled to require that
the  Agent or any  Lender  exercise  any  right,  assert  any  claim or  demand,
foreclose against or enforce any remedy  whatsoever  against the Company (or any
other  Person)  before or as a condition to the  obligations  of such  Guarantor
hereunder.  Each  Guarantor  hereby  acknowledges  that it is fully aware of the
terms and conditions and has received a copy of each Credit Document to which it
or any  other  Credit  Party is a party and is fully  aware of the  transactions
contemplated thereby.

(b) Each Guarantor  agrees that the Obligations may at any time and from time to
time exceed the Maximum  Guaranteed  Amount of such  Guarantor  or of all of the
Guarantors without impairing this Guarantee or affecting the rights and remedies
of the Agent and the Lenders hereunder.

(c) No payment or payments made by the Company, any of the Guarantors, any other
guarantor  or any other  Person or  received  or  collected  by the Agent or any
Lender from the Company, any of the Guarantors, any other guarantor or any other
Person by virtue of any action or proceeding or any set-off or  appropriation or
application  at any time or from time to time in  reduction  of or in payment of
the Obligations shall be deemed to modify,  reduce,  release or otherwise affect
the liability of any Guarantor  hereunder which shall,  notwithstanding any such
payment or payments other than payments made by such Guarantor in respect of the
Obligations or payments  received or collected from such Guarantor in respect of
the Obligations,  remain liable for the Obligations up to its Maximum Guaranteed
Amount until such time as the  Obligations  are paid in full, no Standby Letters
of Credit are outstanding or not fully cash  collateralized  and the Commitments
are terminated.

(d) Each Guarantor  agrees that  whenever,  at any time or from time to time, it
shall make any  payment  to the Agent or any Lender on account of its  liability
hereunder,  it will notify the Agent in writing  that such payment is made under
this Guarantee for such purpose.

                  SECTION 3. Right of Contribution. Each Guarantor hereby agrees
that to the extent that a Guarantor shall have paid more than its  proportionate
share of any payment made  hereunder,  such Guarantor  shall be entitled to seek
and receive  contribution from and against any other Guarantor hereunder who has
not paid its  proportionate  share of such payment.  Each  Guarantor's  right of
contribution  shall be subject to the terms and  conditions of Section 5 hereof.
The provisions of this Section 3 shall in no respect limit the  obligations  and
liabilities  of any Guarantor to the Agent and the Lenders,  and each  Guarantor
shall remain liable to the Agent and the Lenders for the full amount  guaranteed
by such Guarantor hereunder.

                  SECTION 4. Right of Set-off.  Upon the  occurrence  and during
the  continuance  of any Event of  Default  specified  in the  Revolving  Credit
Agreement,  each Guarantor hereby irrevocably authorizes each Lender at any time
and from time to time without notice to such  Guarantor or any other  Guarantor,
any such  notice  being  expressly  waived by each  Guarantor,  to  set-off  and
appropriate and apply any and all deposits (general or special,  time or demand,
provisional or final), in any currency,  and any other credits,  indebtedness or
claims,  in any currency,  in each case whether direct or indirect,  absolute or
contingent, matured or unmatured, at any time held or owing by such Lender to or
for the credit or the account of such  Guarantor,  or any part thereof,  in such
amounts as such Lender may elect,  against and on account of the obligations and
liabilities  of such  Guarantor  to such  Lender  hereunder  and claims of every
nature and description of such Lender against such  Guarantor,  in any currency,
whether arising hereunder,  under the Revolving Credit Agreement,  the Revolving
Notes, the Swing Line Note, the Standby Letters of Credit or otherwise under any
other Credit Document, as such Lender may elect, whether or not the Agent or any
Lender  has  made  any  demand  for  payment  and  although  such   obligations,
liabilities  and claims may be contingent  or  unmatured.  Each Lender agrees to
notify such Guarantor  promptly of any such set-off and the application  made by
such Lender,  provided that the failure to give such notice shall not affect the
validity of such set-off and  application.  The rights of each Lender under this
Section  are in  addition  to other  rights  and  remedies  (including,  without
limitation, other rights of set-off) which such Lender may have.

                  SECTION 5. Subrogation,  etc.  Notwithstanding  any payment or
payments made by any of the  Guarantors  hereunder or any set-off or application
of funds of any of the Guarantors by any Lender, no Guarantor shall exercise any
of the rights of the Agent or any Lender which the  Guarantor may acquire by way
of  subrogation,  by any payment  made  hereunder,  by reason of such set-off or
application of funds or otherwise, against the Company or any other Guarantor or
any collateral  security or guarantee or right of set-off held by any Lender for
the payment of the  Obligations,  nor shall any Guarantor seek or be entitled to
seek any contribution or  reimbursement  from the Company or any other Guarantor
in respect of payments made by such Guarantor hereunder, until all amounts owing
to the Agent and the  Lenders by the Company on account of the  Obligations  are
paid in full,  no Standby  Letters of Credit are  outstanding  or not fully cash
collateralized  and the Commitments are terminated.  If any amount shall be paid
to any Guarantor on account of such subrogation or  reimbursement  rights at any
time when all of the  Obligations  shall not have been paid in full, any Standby
Letter of Credit shall be  outstanding or not fully cash  collateralized  or the
Commitments  shall not have been  terminated,  such amount shall be held by such
Guarantor in trust for the Agent and the Lenders, segregated from other funds of
such Guarantor,  and shall, forthwith upon receipt by such Guarantor,  be turned
over to the Agent in the exact form received by such Guarantor (duly indorsed by
such  Guarantor  to  the  Agent,  if  required),   to  be  applied  against  the
Obligations,  whether  matured or  unmatured,  in such order as  required by the
applicable Credit Documents.

                  SECTION 6.  Amendments,  etc. with respect to the Obligations;
Waiver  of   Rights.   Each   Guarantor   shall   remain   obligated   hereunder
notwithstanding  that,  without any  reservation of rights against any Guarantor
and without  notice to or further  assent by any  Guarantor,  (i) any demand for
payment  of any of the  Obligations  made  by the  Agent  or any  Lender  may be
rescinded  by  such  party  and  any  of the  Obligations  continued,  (ii)  the
Obligations,  or the  liability of any other party upon or for any part thereof,
may,  from time to time,  in whole or in part,  be renewed,  extended,  amended,
modified, accelerated, compromised, waived, surrendered or released by the Agent
or any Lender,  (iii) the Revolving Credit  Agreement,  the Revolving Notes, the
Swing Line Note,  the other Credit  Documents,  any Standby Letter of Credit and
any other  collateral  security  document  or other  guarantee  or  document  in
connection therewith may be amended,  modified,  supplemented or terminated,  in
whole or in part, as the Agent and/or any Lender may deem advisable from time to
time,  and (iv) any  collateral  security,  guarantee or right of set-off at any
time held by the Agent or any Lender for the payment of the  Obligations  may be
sold,  exchanged,  waived,  surrendered  or released.  Neither the Agent nor any
Lender shall have any obligation to protect,  secure, perfect or insure any Lien
at any time held by it as security for the  Obligations or for this Guarantee or
any property  subject thereto.  When making any demand hereunder  against any of
the  Guarantors,  the Agent or any Lender may, but shall be under no  obligation
to, make a similar  demand on the Company or any other  Guarantor or  guarantor,
and any failure by the Agent or any Lender to make any such demand or to collect
any  payments  from the Company or any such other  Guarantor or guarantor or any
release of the Company or such other  Guarantor or  guarantor  shall not relieve
any of the  Guarantors in respect of which a demand or collection is not made or
any  of  the  Guarantors  not  so  released  of  their  several  obligations  or
liabilities  hereunder,  and shall not impair or affect the rights and remedies,
express or implied,  or as a matter of law,  of the Agent or any Lender  against
any of the  Guarantors.  For the  purposes  hereof  "demand"  shall  include the
commencement and continuance of any legal proceedings.  EACH GUARANTOR EXPRESSLY
AND  IRREVOCABLY  WAIVES THE BENEFITS  AFFORDED TO IT UNDER  SECTIONS  49-25 AND
49-26 OF THE CODE OF  VIRGINIA  (1950),  AS AMENDED,  OR ANY SIMILAR  STATUTE OR
COMMON LAW.

                  SECTION  7.  Guarantee   Absolute  and   Unconditional.   Each
Guarantor  waives  any and all notice of the  creation,  renewal,  extension  or
accrual  of any of the  Obligations  and notice of or proof of  reliance  by the
Agent or any Lender upon this  Guarantee or  acceptance of this  Guarantee.  The
Obligations, and any of them, shall conclusively be deemed to have been created,
contracted or incurred,  or renewed,  extended,  annexed or waived,  in reliance
upon  this  Guarantee,  and  all  dealings  between  the  Company  or any of the
Guarantors and the Agent or any Lender shall likewise be  conclusively  presumed
to have been had or consummated in reliance upon this Guarantee.  Each Guarantor
waives diligence, presentment, protest, demand for payment and notice of default
or  nonpayment to or upon the Company or any of the  Guarantors  with respect to
the  Obligations or this Guarantee.  Each Guarantor  understands and agrees that
this Guarantee  shall be construed as a continuing,  absolute and  unconditional
guarantee of payment,  and not of collection,  without regard to (whether or not
the  Guarantor or the Company  shall have any  knowledge or notice of any of the
following)  (a) the  validity,  regularity  or  enforceability  of the Revolving
Credit Agreement,  the Revolving Notes, the Swing Line Note, the Standby Letters
of Credit,  any of the other Credit  Documents,  any of the  Obligations  or any
other  collateral  security  therefore  or  guarantee  or right of set-off  with
respect  thereto  at any  time or from  time to time  held by the  Agent  or any
Lender,  (b) any  defense,  set-off  or  counterclaim  (other  than a defense of
payment or performance)  which may at any time be available to or be asserted by
the Company against the Agent or any Lender,  (c) any termination,  amendment or
modification of, or deletion from, or addition or supplement to, or other change
in any of the Credit Documents or any other  instrument or agreement  applicable
to any of the parties to such  agreements,  or any  furnishing  or acceptance of
additional  security,  or any release of, exchange or action with respect to any
security, for the obligations of the Company under the Credit Documents,  or the
failure of any  security or the failure of any Person to perfect any interest in
any collateral security;  (d) any exercise,  nonexercise or waiver of any right,
remedy,  power or  privilege  under or in respect of any Credit  Document or any
obligation  or liability  contained  therein or any failure to mitigate  damages
under any Credit  Document  or any waiver of any such  right,  remedy,  power or
privilege  or any  failure to give any notice  (including  notice of an Event of
Default)  to any Credit  Party;  (e) any  extension  of time for  payment of any
Obligation,  or of the time for performance of any other obligations,  covenants
or agreements under or arising out of any Credit  Document,  or the extension or
the renewal of any  thereof;  and (f) any other law,  rule,  regulation,  event,
condition or circumstance  whatsoever (with or without notice to or knowledge of
the Company or such  Guarantor)  which  constitutes,  or might be  construed  to
constitute,  an equitable or legal discharge of the Company for the Obligations,
or of such  Guarantor  under  this  Guarantee  (or of a  guarantor  or surety in
general),  in bankruptcy or in any other instance.  When pursuing its rights and
remedies  hereunder  against any  Guarantor,  the Agent and any Lender may,  but
shall be under no obligation  to, pursue such rights and remedies as it may have
against the Company or any other  Person or against any  collateral  security or
guarantee for the Obligations or any right of set-off with respect thereto,  and
any failure by the Agent or any Lender to pursue  such other  rights or remedies
or to collect  any  payments  from the  Company  or any such other  Person or to
realize upon any such  collateral  security or guarantee or to exercise any such
right of set-off,  or any release of the Company or any such other Person or any
such collateral security,  guarantee or right of set-off, shall not relieve such
Guarantor of any liability hereunder,  and shall not impair or affect the rights
and remedies,  whether express,  implied or available as a matter of law, of the
Agent or any Lender against such Guarantor.  This Guarantee shall remain in full
force and  effect and be  binding  in  accordance  with and to the extent of its
terms upon each  Guarantor and the  successors  and assigns  thereof,  and shall
inure  to the  benefit  of the  Agent  and the  Lenders,  and  their  respective
successors,  indorsees,  transferees and assigns,  until all the Obligations and
the obligations of each Guarantor under this Guarantee shall have been satisfied
by payment in full, no Standby Letter of Credit shall remain  outstanding or not
fully   cash   collateralized   and  the   Commitments   shall  be   terminated,
notwithstanding  that from time to time during the term of the Revolving  Credit
Agreement the Company may be free from any Obligations.

                  SECTION 8. Reinstatement.  This Guarantee shall continue to be
effective,  or be reinstated  automatically,  as the case maybe,  if at any time
payment,  or any part thereof,  of any of the  Obligations  is rescinded or must
otherwise  be  restored  or  returned  by the  Agent  or  any  Lender  upon  the
insolvency,  bankruptcy,  dissolution,  liquidation  or  reorganization  of  the
Company  or any  Guarantor,  or  upon or as a  result  of the  appointment  of a
receiver,  intervenor or conservator  of, or trustee or similar officer for, the
Company or any Guarantor or any substantial part of its property,  or otherwise,
all as though  such  payments  had not been  made.  If an event  permitting  the
declaration  of default under a Credit  Document shall at any time have occurred
and be  continuing,  and such  declaration  of  default  shall  at such  time be
prevented by reason of the pendency against the Company or any other Person of a
case or proceeding  under a bankruptcy or insolvency law, each Guarantor  agrees
that, for purposes of this Guarantee and its obligations hereunder,  such Credit
Document  shall be deemed to have been  declared in default with the same effect
as if such Credit  Document had been  enforceable  in accordance  with the terms
thereof,  and each Guarantor  shall  forthwith pay the amounts  specified by the
Agent or any Lenders to be paid  thereunder,  any interest thereon and any other
amounts guaranteed hereunder without further notice or demand.

                  SECTION  9.  Payments;  Execution  and  Delivery  Taxes.  Each
Guarantor  hereby  guarantees that payments  hereunder will be paid to the Agent
without  set-off  or  counterclaim  in U.S.  Dollars  at the office of the Agent
located at NationsBank,  N.A., Kay Finlaw-Creel,  VA-200-05-02,  8300 Greensboro
Drive,  Suite 550,  McLean,  VA 22102,  or such other office of the Agent in the
United  States of  America as the Agent may from time to time  designate  to the
Guarantors by written notice.

     SECTION  10.   Representations   and  Warranties.   Each  Guarantor  hereby
     represents and warrants that:

                  (a) such Guarantor is a corporation, limited liability company
or partnership, as the case may be, duly organized, validly existing and in good
standing under the laws of the jurisdiction in which it is organized and has the
corporate,  limited liability company or partnership power and authority and the
legal right to own and operate its  property,  to lease the property it operates
and to conduct the business in which it is currently engaged;

                  (b)  such  Guarantor  has  the  corporate,  limited  liability
company or  partnership  power and  authority and the legal right to execute and
deliver, and to perform its obligations under this Guarantee,  and has taken all
necessary  corporate,   limited  liability  company  or  partnership  action  to
authorize its execution, delivery and performance of this Guarantee;

                  (c) this Guarantee  constitutes  the legal,  valid and binding
obligations of such Guarantor  enforceable  against such Guarantor in accordance
with  its  terms,  except  as  enforceability  may  be  limited  by  bankruptcy,
insolvency,  reorganization,  moratorium,  fraudulent conveyance or similar laws
affecting  the  enforcement  of  creditors'  rights  generally  and  by  general
principles  of  equity  (regardless  of  whether  enforcement  is  sought  in  a
proceeding in equity or at law);

                  (d) the execution,  delivery and performance by such Guarantor
of this Guarantee will not violate any certificate of incorporation,  by-laws or
other charter or formation documents,  or any applicable law, rule or regulation
or any contract, agreement or instrument (including agreements or instruments of
indebtedness) applicable to or binding upon such Guarantor;

                  (e) no consent or authorization  of, filing with, or other act
by or in respect of, any arbitrator or  Governmental  Body and no consent of any
other Person (including, without limitation, any stockholder or creditor of such
Guarantor) is required in connection with the execution, delivery,  performance,
validity or enforceability by or against such Guarantor of this Guarantee; and

                  (f) there is no action,  suit,  investigation or proceeding by
or before  any  court,  administrative  agency or other  governmental  authority
pending or, to the knowledge of such Guarantor, threatened which involves any of
the transactions  contemplated by this Guarantee or would affect  materially the
ability  (financial or otherwise) of such  Guarantor to perform its  obligations
hereunder.

         Each Guarantor agrees that the foregoing representations and warranties
shall be deemed to have been made by such  Guarantor on each Funding Date by the
Company under the Revolving  Credit  Agreement on and as of such Funding Date as
though made hereunder on and as of such Funding Date.

         SECTION 11.  Severability.  Any  provision of this  Guarantee  which is
prohibited or unenforceable in any jurisdiction  shall, as to such jurisdiction,
be ineffective to the extent of such  prohibition  or  unenforceability  without
invalidating  the  remaining  provisions  hereof,  and any such  prohibition  or
unenforceability   in  any   jurisdiction   shall  not   invalidate   or  render
unenforceable such provision in any other jurisdiction.

     SECTION 12. Section  Headings.  The Section headings used in this Guarantee
     are  for   convenience  of  reference  only  and  are  not  to  affect  the

     hereof.

         SECTION 13. No Waiver;  Cumulative Remedies.  Neither the Agent nor any
Lender shall, by any act (except by a written instrument  pursuant to Section 14
hereof), delay,  indulgence,  omission or otherwise be deemed to have waived any
right or remedy  hereunder  or to have  acquiesced  in any  default  or Event of

to  exercise,  nor any  delay in  exercising,  on the  part of the  Agent or any
Lender,  any  right,  power or  privilege  hereunder  shall  operate as a waiver
thereof.  No  single  or  partial  exercise  of any  right,  power or  privilege
hereunder shall preclude any other or further  exercise  thereof or the exercise
of any other right,  power or privilege.  A waiver by the Agent or any Lender of

bar to any right or remedy which the Agent or such Lender would  otherwise  have
on any future occasion.  The rights and remedies herein provided are cumulative,

remedies provided by law.

Guarantee  shall be binding upon the  successors  and permitted  assigns of each

     with sections 9.15 and 9.13 of the Revolving Credit Agreement.

         SECTION  18.   Submission  To  Jurisdiction;   Waivers.   Any  judicial
proceeding  brought  against any Guarantor with respect to this Guarantee or the
transactions  contemplated  hereby  may be  brought  in any  court of  competent
jurisdiction in the Commonwealth of Virginia,  and, by execution and delivery of
this Guarantee, each Guarantor (a) accepts,  generally and unconditionally,  the
nonexclusive  jurisdiction  of such courts and any related  appellate  court and
irrevocably  agrees to be bound by any judgment  rendered  thereby in connection
with this Guarantee or the transactions  contemplated hereby and (b) irrevocably
waives any  objection it may now or  hereafter  have as to the venue of any such
proceeding  brought  in such a court  or that  such a court  is an  inconvenient
forum.  Each Guarantor  hereby waives  personal  service of process and consents
that service of process upon it may be made by  certified  or  registered  mail,

affect the right of any Lender or the Agent to serve process in any other manner
permitted  by law or shall  limit the right of any  Lender or the Agent to bring

THEY ARE PARTIES  INVOLVING  THIS  GUARANTEE  OR THE  TRANSACTIONS  CONTEMPLATED
HEREBY.

         SECTION 19. Authority of Agent.  Each Guarantor  acknowledges  that the
rights and  responsibilities  of the Agent under this  Guarantee with respect to
any action  taken by the Agent or the exercise or  non-exercise  by the Agent of
any option,  right,  request,  judgment or other  right or remedy  provided  for
herein or resulting or arising out of this Guarantee shall, as between the Agent
and the Lenders, be governed by the Revolving Credit Agreement and by such other
agreements  with respect thereto as may exist from time to time among them, but,
as  between  the  Agent and such  Guarantor,  the  Agent  shall be  conclusively
presumed to be acting as Agent for the Lenders with full and valid  authority so
to act or refrain from acting,  and neither such Guarantor,  the Company nor any
other  Guarantor  shall be under any  obligation,  or  entitlement,  to make any
inquiry respecting such authority.

         IN WITNESS  WHEREOF,  each of the undersigned has caused this Guarantee
to be duly executed and delivered by its duly  authorized  officer as of the day

provided,  however,  notwithstanding  anything to the contrary contained herein,
the  Debtor is not  assigning,  pledging  or  otherwise  encumbering  under this
Security Agreement its interests in any Federal Contract to which it is a party,
or in accounts or receivables due to Debtor under such Federal Contract,  to the
extent,  but only to the extent,  such assignment,  pledge or other  encumbrance
would  breach or violate or would cause Debtor to breach or violate such Federal
Contract or statutes or regulations applicable thereto, it being understood that
this proviso does not apply to, or in any way limit, Debtor's assignment, pledge
or encumbrance of Proceeds of all Federal Contracts to which it is a party.

Section  2.02.  Continuing  Liability  of the  Debtor.  Anything  herein  to the
contrary notwithstanding,  the Debtor shall remain liable to observe and perform
all the  terms and  conditions  to be  observed  and  performed  by it under any
contract,   agreement,   warranty  or  other  obligation  with  respect  to  the
Collateral;  and  shall do  nothing  to impair  the  security  interests  herein
granted.  The Agent shall not have any  obligation  or liability  under any such
contract,  agreement, warranty or obligation by reason of or arising out of this
Security  Agreement  or the receipt by the Agent of any payment  relating to any
Collateral,  nor shall the Agent be  required  to perform or fulfill  any of the
obligations of the Debtor with respect to the Collateral, to make any inquiry as
to the nature or sufficiency of any payment received by it or the sufficiency of
the  performance  of any party's  obligations  with  respect to any  Collateral.
Furthermore,  the  Agent  shall not be  required  to file any claim or demand to
collect any amount due or to enforce the performance of any party's  obligations
with respect to, the Collateral.

Section 2.03.     Sales and Collections.

(a) Sales of  Inventory  in the  Ordinary  Course  of  Business.  The  Debtor is
authorized (i) to sell in the ordinary course of its business for fair value and
on an  arm's-length  basis  any of its  Inventory  normally  held by it for such
purpose and (ii) to use and consume, in the ordinary course of its business, any
raw materials,  supplies and materials normally held by it for such purpose. The
Agent may, upon the occurrence of any Event of Default, without cause or notice,
curtail or terminate such authority at any time.

(b) Collection of Receivables. The Debtor is authorized to collect amounts owing
to it with respect to the Collateral, except as otherwise provided in connection
with the Assignment of Federal Contract, if any as provided herein. However, the
Agent may, upon and during the continuance of an Event of Default or a Potential
Event of Default, notify Account Debtors obligated to make payments under any or
all Receivables or Other  Intangibles that the Agent has a security  interest in
such Collateral and that payments shall be made directly to the Agent.  Upon the
request of the Agent upon and during the continuance of an Event of Default or a
Potential  Event of Default,  as the case may be, the Debtor will so notify such
Account  Debtors  and  will  execute  such  contract  assignments,   notices  of
assignment or other  documents as may be required by such Account  Debtors.  The
Debtor will use all  reasonable  efforts to cause each Account  Debtor to comply
with the foregoing  instruction.  In furtherance  of the  foregoing,  the Debtor
authorizes the Agent upon and during the continuance of an Event of Default or a
Potential  Event of Default (i) to ask for,  demand,  collect,  receive and give
acquittances  and  receipts  for any and all amounts due and to become due under
any Collateral and in the name of the Debtor or its own name or otherwise,  (ii)
to  take  possession  of,  endorse  and  collect  any  checks,   drafts,  notes,
acceptances  or other  instruments  for the  payment  of  monies  due  under any
Collateral  and (iii) to file any claim or take any other action in any court of
law or equity or  otherwise  which it may deem  appropriate  for the  purpose of
collecting  any  amounts  due under any  Collateral.  The  Agent  shall  have no
obligation  to obtain or record any  information  relating to the source of such
funds or the obligations in respect of which payments have been made.

Section 2.04.     Segregation of Proceeds.

(a) Cash Collateral  Account  Maintained by Agent. Upon an Event of Default or a
Potential  Event of  Default,  the Agent shall have the right at any time during
the  continuance  thereof to cause to be opened and  maintained at the office of
the Agent in McLean,  Virginia a  non-interest  bearing  bank account (the "Cash
Collateral  Account") which will contain only Proceeds.  Any "cash proceeds" (as
such term is defined  in  Section  9-306(1)  of the UCC)  received  by the Agent
directly from Account  Debtors  obligated to make payments under  Receivables or
Other Intangibles  pursuant to Section 2.3 hereof or from the Debtor pursuant to
clause (b) of this Section 2.4,  whether  consisting of checks,  notes,  drafts,
bills of exchange, money orders,  commercial paper or other Proceeds received on
account of any  Collateral,  shall be promptly  deposited in the Cash Collateral
Account, and until so deposited shall be held in trust for the Agent as property
of the  Agent  and shall not be  commingled  with any  funds of the  Debtor  not
constituting  Proceeds  of  Collateral.  The name in which  the Cash  Collateral
Account is carried shall clearly  indicate that the funds deposited  therein are
the  property  of the  Debtor,  subject to the  security  interest  of the Agent
hereunder. Such Proceeds, when deposited,  shall continue to be security for the
Obligations   and  shall  not  constitute   payment  thereof  until  applied  as
hereinafter  provided.  The Agent shall have sole  dominion and control over the
funds deposited in the Cash Collateral Account,  and such funds may be withdrawn
therefrom only by the Agent.

(b) Deposit of  Proceeds  by the Debtor.  Upon notice by the Agent to the Debtor
that the Cash  Collateral  Account has been  opened,  the Debtor shall cause all
cash  Proceeds  collected  by it to be  delivered  to the Agent  forthwith  upon
receipt,  in the original  form in which  received  (with such  endorsements  or
assignments as may be necessary to permit collection  thereof by the Agent), and
for such  purpose the Debtor  hereby  irrevocably  authorizes  and  empowers the
Agent,  its officers,  employees and  authorized  agents to endorse and sign the
name of the Debtor on all checks, drafts, money orders or other media of payment
so delivered,  and such endorsements or assignments shall, for all purposes,  be
deemed to have been made by the Debtor prior to any  endorsement  or  assignment
thereof by the Agent.  The Agent may use any  convenient or customary  means for
the purpose of collecting  such checks,  drafts,  money orders or other media of
payment.

Section 2.05.  Verification  of  Receivables.  The Agent shall have the right to
make test  verifications of Receivables in any reasonable manner and through any
medium that it considers  advisable,  and the Debtor  agrees to furnish all such
assistance and  information  as the Agent may  reasonable  require in connection
therewith.  The Debtor at its expense will cause its chief financial  officer to
furnish to the Agent at any reasonable  time and from time to time promptly upon
the Agent's reasonable request,  the following reports:  (i) a reconciliation of
all Receivables, (ii) an aging of all Receivables, (iii) trial balances and (iv)
a test verification of such Receivables as the Agent may request.


Section 2.06.     Release of Collateral.

(a) Security  Interest of Agent Ceases Upon Permitted  Dispositions.  The Debtor
may sell or realize upon or transfer or otherwise  dispose of Collateral only to
the extent permitted by Section 4.13, and the security interests of the Agent in
such  Collateral so sold,  realized upon or disposed of (but not in the Proceeds
arising from such sale, realization or disposition) shall cease immediately upon
such sale, realization or disposition, without any further action on the part of
the Agent.  The Agent,  if requested in writing by the Debtor but at the expense
of the Debtor,  is hereby  authorized  and  instructed to deliver to the Account
Debtor or the purchaser or other transferee of any such Collateral a certificate
stating  that the Agent no longer  has a  security  interest  therein,  and such
Account Debtor or such purchaser or other  transferee  shall be entitled to rely
conclusively on such certificate for any and all purposes.

(b) Filing of  Termination  Statements.  Upon the  payment in full of all of the
Obligations  and if  there  is no  commitment  by any  Lender  to  make  further
advances,  incur obligations or otherwise give value, the Agent will (as soon as
reasonably  practicable  after receipt of notice from the Debtor  requesting the
same but at the  expense  of the  Debtor)  deliver  to the  Debtor  (i) for each
jurisdiction  in  which a UCC  financing  statement  is on file to  perfect  the
security  interests  granted to the Agent  hereunder,  a  termination  statement
(appropriately  completed)  to the  effect  that the  Agent no  longer  claims a
security interest under such financing statement,  and (ii) such other documents
as  the  Debtor  shall  reasonably  request   evidencing   satisfaction  of  the
Obligations  and the  release  of the  security  interests  granted to the Agent
hereunder.

ARTICLE III.

                                      REPRESENTATIONS AND WARRANTIES

         The Debtor represents and warrants that:

Section 3.01. Title to Collateral.  Except for the security interests granted to
the Agent  pursuant to this  Security  Agreement  and as otherwise  permitted by
Section 6.2(a) of the Revolving Credit  Agreement,  the Debtor is the sole owner
of each item of the Collateral,  having good and marketable title thereto,  free
and clear of any and all Liens.


Section 3.02.     Validity, Perfection and Priority of Security Interests.

(a) By complying  with Section 4.1 hereof,  the Debtor will have created a valid
security  interest in favor of the Agent in all existing  Collateral  and in all
identifiable  Proceeds of such  Collateral,  which security  interest (except in
respect of  Collateral  not located at a facility  identified  on  Schedule  3.7
hereto  and motor  vehicles  for  which the  exclusive  manner of  perfecting  a
security interest therein is by noting such security interest in the certificate
of title in accordance with local law) would be prior to the claims of a trustee
in bankruptcy under Section 544(a) of the Bankruptcy Code. Continuing compliance
by the Debtor  with the  provisions  of Section  4.2 hereof will also (i) create
valid security interests in all Collateral acquired after the date hereof and in
all  identifiable  Proceeds  of such  Collateral  and (ii) cause  such  security
interests in all Collateral and in all Proceeds which are (A) identifiable  cash
Proceeds of  Collateral  covered by  financing  statements  required to be filed
hereunder,  (B)  identifiable  Proceeds  in  which a  security  interest  may be
perfected  by such  filing  under  the UCC and  (C)  any  Proceeds  in the  Cash
Collateral Account to be duly perfected under the UCC, in each case prior to the
claims of a trustee in bankruptcy  under the Bankruptcy  Code (except in respect
of Collateral not located at a facility identified on Schedule 3.5 hereto).

(b) The  security  interests  of the  Agent  in the  Collateral  located  at the
facilities identified on Schedule 3.5 hereto rank first in priority.  Other than
financing   statements  or  other  similar  documents  perfecting  the  security
interests  in favor of the  Agent,  no  financing  statements,  deeds of  trust,
mortgages or similar documents covering all or any part of the Collateral are on
file or of record in any  government  office in any  jurisdiction  in which such
filing or recording  would be  effective to perfect a security  interest in such
Collateral,  nor is any of the Collateral in the possession of any Person (other
than the Debtor) asserting any claim thereto or security interest therein.

Section 3.03.  Enforceability of Receivables and Other Intangibles.  To the best
knowledge of the Debtor,  each  Receivable  and Other  Intangible is a valid and
binding obligation of the related Account Debtor in respect thereof, enforceable
in accordance with its terms,  except as such  enforceability  may be limited by
applicable bankruptcy,  insolvency,  reorganization,  moratorium or similar laws
affecting  the  enforcement  of  creditors'  rights  generally  and  by  general
provisions of equity (regardless of whether such enforceability is considered in
a  proceeding  in equity or at law),  and  complies  with any  applicable  legal
requirements.

Section 3.04.  Place of Business.  Schedule 3.4  correctly  sets forth the chief
executive  office and principal  place of business of the Debtor and the offices
of the Debtor where records  concerning  Receivables  and Other  Intangibles are
kept.

Section 3.05.  Location of  Collateral.  Schedule 3.5  correctly  sets forth the
location of all Equipment and Inventory,  other than rolling stock, aircraft and
goods in transit.  Except as otherwise  specified in Schedule 3.5, all Inventory
and Equipment  has been located at the address  specified on Schedule 3.5 at all
times during the  four-month  period prior to the date hereof while owned by the
Debtor.  All Inventory has been and will be produced in compliance with the Fair
Labor Standards Act, 29 U.S.C.  ss.ss.  201-219,  except for such non-compliance
which could not reasonably be expected to have a material  adverse effect on the
Debtor. No Inventory is evidenced by a negotiable  document of title,  warehouse
receipt  or bill of  lading.  No  non-negotiable  document  of title,  warehouse
receipt or bill of lading has been  issued to any person  other than the Debtor,
and the Debtor has retained possession of all of such non-negotiable  documents,
warehouse receipts and bills of lading. No amount payable under or in connection
with  any  of  the  Collateral  is  evidenced  by  promissory   notes  or  other
instruments.

Section 3.06.  Trade Names.  Schedule 3.6 correctly sets forth any and all trade
names,  division  names,  assumed  names or other  names  under which the Debtor
currently  transacts  business or has transacted  business within the four-month
period prior to the date hereof.

     Section 3.07. Patents and Trademarks. Schedule 3.7 correctly sets forth all
     Patents,  Patent licenses,  Trademarks and Trademark  licenses now owned by
     the Debtor.

ARTICLE IV.

                                                COVENANTS

                  The Debtor covenants and agrees that until all obligations and
liabilities in respect of the Obligations  shall have performed and paid in full
and  until  no  Standby   Letters  of  Credit  are  outstanding  or  fully  cash
collateralized and the Commitments are terminated:

Section 4.01. Perfection of Security Interests. The Debtor will, at its expense,
cause all filings and recordings and other actions  specified on Schedule 4.1 to
have been completed on or prior to the Effective Date.

Section 4.02.     Further Actions.

(a) At all times after the date hereof, the Debtor will, at its expense,  comply
with the following:

(i) as to all Receivables,  Other Intangibles,  Equipment and Inventory, it will
cause UCC financing statements and continuation statements to be filed and to be
on file in all  applicable  jurisdictions  as required  to perfect the  security
interests  granted to the Agent  hereunder,  to the extent that  applicable  law
permits perfection of a security interest by filing under the UCC;

(ii)  as to all  Proceeds,  it  will  cause  all UCC  financing  statements  and
continuation  statements  filed in accordance with clause (i) above to include a
statement or a checked box  indicating  that Proceeds of all items of Collateral
described herein are covered;

(iii) as to any amount payable under or in connection with any of the Collateral
which  shall  be or  shall  become  evidenced  by any  promissory  note or other
instrument,  the  Debtor  will  promptly  (but in no event  later  than ten (10)
Business Days after receipt of such note or instrument), pledge and deliver such
note or other  instrument to the Agent as part of the Collateral,  duly endorsed
in a manner reasonably satisfactory to the Agent;

(iv) at the request of the Agent,  the Debtor shall deliver all other Collateral
consisting  of  certificated  securities,  endorsed  for  transfer  in a  manner
reasonably  satisfactory  to the Agent (or  execute  a  securities  intermediary
account  control  agreement  to the  extent  possession  by the  Agent  of  such
securities is not feasible); and

(v) as to all Patents,  Patent licenses,  Trademarks or Trademark licenses,  the
Debtor will effect the recordation or renewal of the recordation of the security
interests of the Agent therein so as to maintain  valid and  perfected  security
interests therein under all applicable state and federal laws.

(b) Further  Assurances.  The Debtor will, from time to time and at its expense,
execute, deliver, file or record such UCC financing statements, applications for
certificates  of title  and such  other  statements,  assignments,  instruments,
documents,  agreements  or other  papers and take any other  action  that may be
necessary or desirable,  or that the Agent may reasonably  request,  in order to
create,  preserve,  perfect,  confirm or validate the  security  interest of the
Agent in the Collateral, to enable the Agent to obtain the full benefits of this
Security  Agreement  or to enable it to exercise  and enforce any of its rights,
powers and remedies hereunder,  including, without limitation, its right to take
possession of the Collateral.

(c) Signature. To the fullest extent permitted by law, the Debtor authorizes the
Agent to sign and file  financing and  continuation  statements  and  amendments
thereto with respect to the Collateral without its signature thereon.

Section 4.03. Change of Name, Identity or Structure.  The Debtor will not change
its name, identity or corporate structure in any manner and, except as set forth
on  Schedule  3.6,  will not conduct its  business  under any trade,  assumed or
fictitious  name unless it shall have given the Agent at least  forty-five  (45)
days'  prior  written  notice  thereof  and shall have taken all action (or made
arrangements to take such action  substantially  simultaneously with such change
if it is  impossible  to take such action in advance)  necessary  or  reasonably
requested  by the  Agent  to  amend  any  financing  statement  or  continuation
statement relating to the security interests granted hereby in order to preserve
such  security  interests  and to  effectuate  or maintain the priority  thereof
against all Persons.

Section 4.04.  Place of Business and Collateral.  The Debtor will not change the
location of (i) its places of business, (ii) its chief executive office or (iii)
the  office or other  locations  where it keeps or holds any  Collateral  or any
records relating thereto from the applicable  location listed on Schedule 3.4 or
3.5 unless,  prior to such change, it notifies the Agent forty-five (45) days in
advance of such change,  makes all UCC filings required by Section 4.2 and takes
all other action necessary or that the Agent may reasonably request to preserve,
perfect,  confirm and protect the security  interests granted hereby. The Debtor
will in no event  change the  location of any  Collateral  if such change  would
cause the security  interest granted hereby in such Collateral to lapse or cease
to be  perfected.  The Debtor  will at all times  maintain  its chief  executive
office within one of the forty-eight contiguous states in which Article 9 of the
uniform commercial code is in effect.

Section  4.05.  Fixtures.  The Debtor will not permit any  Equipment to become a
fixture  unless it shall  have  given the  Agent at least ten (10)  days'  prior
written  notice  thereof and shall have taken all such action and  delivered  or
caused to be delivered to the Agent all  instruments  and documents,  including,
without  limitation,  waivers and subordination  agreements by any landlords and
mortgagees, and filed all financing statements necessary or reasonably requested
by the Agent, to preserve and protect the security  interest  granted herein and
to effectuate or maintain the priority  thereof  against all Persons;  provided,
however,  that,  so long as no Event of  Default or  Potential  Event of Default
shall have  occurred  and be  continuing,  the Debtor  shall not be obligated to
comply with the provisions of this Section 4.5 with respect to the first $50,000
of Equipment (determined based on the then fair market value thereof).

Section 4.06.  Maintenance of Records.  The Debtor will keep and maintain at its
own cost and expense complete books and records relating to the Collateral which
are satisfactory to the Agent  including,  without  limitation,  a record of all
payments received and all credits granted with respect to the Collateral and all
of its other  dealings with the  Collateral.  The Debtor will mark its books and
records pertaining to the Collateral to evidence this Security Agreement and the
security interests granted hereby.  For the Agent' further security,  the Debtor
agrees  that the Agent  shall  have a special  property  interest  in all of the
Debtor's  books and records  pertaining to the  Collateral  and the Debtor shall
deliver  and  turn  over any  such  books  and  records  to the  Agent or to its
representatives at any time on demand of the Agent.

Section  4.07.  Compliance  with Laws The  Debtor  will  comply in all  material
respects with all acts, rules,  regulations,  orders,  decrees and directions of
any government or any state or local government  applicable to the Collateral or
any part  thereof or to the  operation of the  Debtor's  business  except to the
extent that the failure to comply  would not have a material  adverse  effect on
the  financial or other  condition of the Debtor;  provided,  however,  that the
Debtor may contest any act, rule, regulation,  order, decree or direction in any
reasonable  manner which shall not, in the sole opinion of the Agent,  adversely
affect the Agent's  rights or, in the case of  Collateral  located at a facility
identified on Schedule 3.7 hereto,  the first priority of its security  interest
in the Collateral.

Section 4.08. Payment of Taxes. The Debtor will pay promptly when due all taxes,
assessments and governmental charges or levies imposed upon the Collateral or in
respect of its income or  profits  therefrom,  as well as all claims of any kind
(including claims for labor, materials and supplies), except that no such charge
need be paid if (i) the  validity  thereof is being  contested  in good faith by
appropriate  proceedings and (ii) such charge is adequately  reserved against in
accordance  with  generally  accepted  accounting  principles,  as  consistently
applied.

Section 4.09.  Compliance with Terms of Accounts and Contracts.  The Debtor will
perform and comply in all material  respects with all of its  obligations  under
all agreements  relating to the Collateral to which it is a party or by which it
is bound.

Section  4.10.  Limitation on Liens on  Collateral.  The Debtor will not create,
permit or suffer to exist,  and will  defend  the  Collateral  and the  Debtor's
rights with respect  thereto  against and take such other action as is necessary
to  remove  any  Lien,  security  interest,  encumbrance,  or claim in or to the
Collateral other than the security interests created hereunder and such Liens to
the  extent  permitted  pursuant  to  Section  6.2(a)  of the  Revolving  Credit
Agreement.

Section 4.11. Limitations on Modifications of Receivables and Other Intangibles;
No Waivers or Extensions.  The Debtor will not (i) amend,  modify,  terminate or
waive any  provisions  of any material  Receivable  or Other  Intangible  in any
manner which might, when taken together with all such other Receivables or Other
Intangibles,  respectively,  materially  reduce the value of all  Receivables or
Other  Intangibles,  respectively,  in the  Collateral,  (ii)  fail to  exercise
promptly and  diligently  each and every  material right which it may have under
each  Receivable  and Other  Intangible  or (iii) fail to deliver to the Agent a
copy of each material demand,  notice or document received by it relating in any
way to any Receivable or Other Intangible.

Section  4.12.   Maintenance  of  Insurance.   The  Debtor  will  maintain  with
financially   sound  insurance   companies   licensed  to  do  business  in  the
jurisdictions  in which the  Collateral  is located  insurance  policies  on the
Inventory and Equipment in accordance  with the  provisions of Section 6.1(m) of
the Revolving Credit Agreement.

Section 4.13.  Limitations on  Dispositions  of Collateral.  The Debtor will not
directly or indirectly (through the sale of stock, merger or otherwise), without
the prior  written  consent of the Agent,  sell,  transfer,  lease or  otherwise
dispose of any of the Collateral,  or attempt, offer or contract to do so except
for (i) sales of Inventory in the ordinary course of its business for fair value
in  arm's-length  transactions  and  (ii) so long as no  Event  of  Default  (or
Potential  Event of Default) has occurred and is continuing,  dispositions  in a
commercially reasonable manner of Equipment which has become redundant, worn out
or obsolete or which should be replaced so as to improve  productivity,  so long
as the  proceeds  of any such  disposition  are (x) used to acquire  replacement
equipment  which has comparable or better utility and equivalent or better value
and which is subject to a first priority security interest in favor of the Agent
therein,  except  as  permitted  by  Section  6.2(a)  of  the  Revolving  Credit
Agreement, or (y) applied to repay the Obligations. The inclusion of Proceeds of
the Collateral under the security interests granted hereby shall not be deemed a
consent by the Agent to any sale or disposition of any Collateral  other than as
permitted by this Section 4.13.

Section 4.14. Further  Identification of Collateral.  The Debtor will furnish to
the Agent from time to time  statements and schedules  further  identifying  and
describing  the  Collateral  and  such  other  reports  in  connection  with the
Collateral as the Agent may reasonably request. The Debtor shall promptly notify
the Agent if the value of the Collateral located at the facilities identified on
Schedule 3.7 hereto is less than 80% of the value of all of the Collateral.

Section  4.15.  Notices.  The  Debtor  will  advise  the Agent  promptly  and in
reasonable detail (i) of any Lien, security interest,  encumbrance or claim made
or  asserted  against  any of the  Collateral,  other  than,  unless  reasonably
requested  by the Agent,  Liens  permitted  by Section  6.2(a) of the  Revolving
Credit  Agreement,  (ii)  of  any  material  change  in the  composition  of the
Collateral,  and (iii) of the  occurrence  of any other event which would have a
material  adverse  effect on the  aggregate  value of the  Collateral  or on the
security interests granted to the Agent in this Security Agreement.

Section 4.16.  Change of Law. The Debtor shall promptly  notify the Agent of any
change in law known to it which (i) adversely  affects or will adversely  affect
the validity,  perfection or priority of the security  interests granted hereby,
(ii)  requires  or will  require a change in the  proceedings  to be followed in
order to maintain and protect such  validity,  perfection  and priority or (iii)
could result in the Agent not having a perfected security interest in any of the
Collateral.

Section 4.17.     Right of Inspection.

(a) Access to Books and Records. The Debtor shall,  following any request by the
Agent and upon reasonable  notice,  permit the Agent or its  representatives  to
have  full  and free  access  during  normal  business  hours to all the  books,
correspondence and records of the Debtor,  and the Agent or its  representatives
may examine the same, take extracts therefrom, make photocopies thereof and have
such discussions with officers,  employees and public  accountants of the Debtor
as the Agent may deem reasonably  necessary,  and the Debtor agrees to render to
the Agent, at the Debtor's cost and expense,  such clerical and other assistance
as  may  be  reasonably  requested  with  regard  thereto.  The  Agent  and  its
representatives  shall upon  reasonable  notice and during normal business hours
also  have the  right to enter  into  and  upon any  premises  where  any of the
Inventory or the  Equipment is located for the purpose of  inspecting  the same,
observing its use or protecting the interests of the Agent therein.

(b)  Audits.  The  Debtor  shall  permit  the  Lenders,   the  Agent  and  their
representatives  and advisors to review the operations of the Debtor and perform
the  audits  and  examinations  as  provided  in  Section  6.1(l) of the  Credit
Agreement.

     Section 4.18.  Maintenance  of Equipment.  The Debtor will, at its expense,
     maintain the Equipment in good operating condition,  ordinary wear and tear
     excepted.

Section 4.19.     Covenants Regarding Patent and Trademark Collateral.

(a)  Generally.  At  such  time as the  Debtor  shall  acquire  any  Patents  or
Trademarks,  it will comply with the terms,  covenants  and  warranties  of this
Section 4.19.

(b) Continued Use of Trademark.  The Debtor (either itself or through licensees)
will, unless the Debtor shall reasonably determine,  after consultation with the
Agent,  that a Trademark  is of  negligible  economic  value to the Debtor,  (i)
continue  to use each  Trademark  on each  and  every  Trademark  class of goods
applicable  to its current  products  and  services as  reflected in its current
catalogs,  brochures and price lists in order to maintain each Trademark in full
force and free from any claim of  abandonment  for non-use,  (ii) maintain as in
the past the quality of products  and  services  offered  under each  Trademark,
(iii) employ each Trademark with the appropriate  notice of  registration,  (iv)
not adopt or use any mark which is confusingly  similar to a colorable imitation
of any Trademark and (v) not (and not permit any licensee or sublicensee thereof
to) do any act or knowingly  omit to do any act whereby any Trademark may become
invalidated.

(c) No  Abandonment.  The Debtor will not,  unless the Debtor  shall  reasonably
determine,  after  consultation  with the Agent,  that a Patent is of negligible
economic  value to the  Debtor,  do any act,  or  knowingly  omit to do any act,
whereby any Patent may be abandoned or dedicated.

(d) Notice of Abandonment or Adverse Determinations. The Debtor shall notify the
Agent  immediately if it knows,  or has reason to know,  that any application or
registration  relating  to any  Patent or  Trademark  may  become  abandoned  or
dedicated,  or of any adverse determination or development  (including,  without
limitation,  the institution of, or any such determination or development in any
proceeding  in the United  States  Patent and  Trademark  Office or any court of
tribunal in any  country)  regarding  the  Debtor's  ownership  of any Patent or
Trademark, its right to register the same or keep and maintain the same.

(e) Filings After Notice to Agent.  In no event shall the Debtor,  either itself
or through any agent,  employee,  licensee or designee,  file an application for
registration  of any  Patent or  Trademark  with the  United  States  Patent and
Trademark  Office or any  similar  office or agency in any other  country or any
political  subdivision  thereof,  unless it promptly informs the Agent and, upon
request of the Agent, executes and delivers any and all agreements, instruments,
documents  and papers as the Agent may request to evidence the Agent's  security
interest in such Patent or Trademark and the goodwill and general intangibles of
the  Debtor  relating  thereto or  represented  thereby,  and the Debtor  hereby
constitutes the Agent its attorney-in-fact to execute and file all such writings
for the foregoing purposes, all such acts of such attorney being hereby ratified
and confirmed.

(f) Pursuit of Applications  and Maintenance of  Registrations.  The Debtor will
take all necessary  steps,  including,  without  limitation,  in any  proceeding
before the United States Patent and  Trademark  Office or any similar  office or
agency in any other country or any political  subdivision  thereof,  to maintain
and pursue each  application  (and to obtain the relevant  registration)  and to
maintain each  registration  of the Patents and  Trademarks,  including  without
limitation, filing of applications for renewal, affidavits of use and affidavits
of incontestability;  provided,  however, that no such Patent or Trademark shall
be required to be  maintained  or pursued to the extent such Patent or Trademark
is  determined  by the  Debtor,  after  consultation  with the  Agent,  to be of
negligible economic value to the Debtor.

(g) Notice of  Infringement.  If any of the Patent and  Trademark  Collateral is
infringed,  misappropriated  or  diluted  by a third  party,  the  Debtor  shall
promptly  notify the Agent after it learns thereof and shall,  unless the Debtor
shall reasonably determine,  after consultation with the Agent, that such Patent
and Trademark Collateral is of negligible economic value to the Debtor, promptly
sue for infringement, misappropriation of dilution, seek injunctive relief where
appropriate   and  recover   any  and  all   damages   for  such   infringement,
misappropriation  or  dilution,  or take such other  action as the Debtor  shall
reasonably deem appropriate  under the  circumstances to protect such Patent and
Trademark Collateral.

Section 4.20.  Termination  of Federal  Contracts.  With respect to each Federal
Contract in respect of which the Debtor is required to execute an  Assignment of
Federal  Contract in accordance with Section 4.21 hereof,  the Debtor shall give
prompt written  notice to the Agent if the U.S.  Government  shall  terminate or
threaten to  terminate  (whether  for  convenience  or default) any such Federal
Contract  with the Debtor  having a value  (including  unexercised  options)  of
$100,000 or more. In addition,  the Debtor shall give prompt  written  notice to
the Agent if the U.S.  Government  shall  terminate or threaten to terminate any
contract between the U.S.  Government and any other prime contractor under which
the  Debtor  is a  subcontractor  if the  value of such  subcontract  (including
unexercised options) is $100,000 or more.

Section 4.21. Federal Contracts.  The Debtor shall provide to the Agent, as soon
as reasonably  practicable but not later than forty-five (45) days following the
end of each Fiscal Quarter,  a report identifying each Federal Contract to which
it is a party,  having  attached  thereto  a copy of the first two pages of such
Federal  Contract  and any  amendment  thereto,  to the  extent  not  previously
provided to the Agent.  At the request of the Agent  (unless an Event of Default
shall have  occurred and be  continuing,  in which case no such request shall be
required),  the Debtor shall  execute and deliver to the Agent an  Assignment of
Federal Contract, in substantially the form of Exhibit A hereto (the "Assignment
of Federal Contract"), and execute any other instruments or take any other steps
required  by the Agent in order  that all moneys due or to become due under such
Federal  Contracts shall be assigned to the Agent and notice thereof given under
the Assignment of Claims Act, including without  limitation  delivery of Notices
of Assignments with respect to each Federal Contract as contemplated by Appendix
A to Exhibit A hereto.

Section 4.22.  Reimbursement  Obligation.  Should the Debtor fail to comply with
the provisions of this Security Agreement, the Revolving Credit Agreement or any
other agreement relating to the Collateral such that the value of any Collateral
or the validity,  perfection,  rank or value of any security interest granted to
the  Agent  hereunder  or  thereunder  is  thereby   diminished  or  potentially
diminished or put at risk (as reasonably  determined by the Agent), the Agent on
behalf of the Debtor may, but shall not be required to,  effect such  compliance
on behalf of the Debtor,  and the Debtor shall  reimburse the Agent for the cost
thereof on demand,  and interest shall accrue on such  reimbursement  obligation
from the date the relevant  costs are incurred  until  reimbursement  thereof in
full at the Default Rate.

ARTICLE V.

                                      REMEDIES; RIGHTS UPON DEFAULT

Section 5.01. UCC Rights.  In the event that any portion of the  Obligations has
been declared or becomes due and payable in accordance with the Revolving Credit
Agreement or other Credit  Documents and such  Obligations have not been paid in
full,  the Agent may in addition to all other rights and remedies  granted to it
in this Security  Agreement and in any other  instrument or agreement  securing,
guarantying,  evidencing or relating to the Obligations, exercise (i) all rights
and  remedies of a secured  party under the UCC (whether or not in effect in the
jurisdiction  where  such  rights  are  exercised)  and  (ii) all  other  rights
available to the Agent at law or in equity.

     Section 5.02.  Payments on Collateral.  Without  limiting the rights of the
     Agent under any other provision of this Security Agreement,  if an Event of
     Default shall occur and be continuing:

(i) all payments  received by the Debtor under or in connection  with any of the
Collateral  shall  be held by the  Debtor  in  trust  for the  Agent,  shall  be
segregated  from other funds of the Debtor and shall  forthwith  upon receipt by
the Debtor be turned  over to the  Agent,  in the same form as  received  by the
Debtor  (duly  indorsed  by the  Debtor  to the  Agent,  if  required  to permit
collection thereof by the Agent); and

(ii) all such  payments  received  by the  Agent  (whether  from the  Debtor  or
otherwise)  may, in the sole  discretion  of the Agent,  be held by the Agent as
collateral  security for, and/or then or at any time thereafter applied in whole
or in part by the Agent to the payment of, the expenses and the  Obligations  as
set forth in Section 5.11 hereof.

Section 5.03.  Possession of Collateral.  In  furtherance of the foregoing,  the
Debtor  expressly  agrees  that,  if an  Event of  Default  shall  occur  and be
continuing, the Agent may (i) by judicial powers, or without judicial process if
it can be done without breach of the peace, enter any premises where any of such
Collateral is or may be located and,  without  charge or liability to the Agent,
seize and remove such  Collateral from such premises and (ii) have access to and
use of the Debtor's books and records relating to such Collateral.

Section 5.04.     Sale of Collateral; Notice.

(a) Sale of Collateral.  The Debtor expressly agrees that if an Event of Default
shall occur and be continuing, the Agent, without demand of performance or other
demand or notice of any kind (except the notice  specified below of the time and
place of any public or private  sale) to or upon the Debtor or any other  Person
(all of which  demands  and/or  notices are hereby  waived by the  Debtor),  may
forthwith (i) apply the cash, if any, then held by it as collateral as specified
in Section  5.11 hereof and (ii) if there shall be no cash or such cash shall be
insufficient to pay the Obligations in full, collect,  receive,  appropriate and
realize upon the Collateral,  and/or sell, assign,  give an option or options to
purchase or otherwise  dispose of and deliver the  Collateral (or contract to do
so) or any part thereof in one or more parcels (which need not be in round lots)
at public or  private  sale,  at any  office of the Agent or  elsewhere  in such
manner as is  commercially  reasonable and, as the Agent may deem best, for cash
or on credit or for future delivery  without  assumption of any credit risk. The
Agent shall have the right upon any such public sale,  and, if the Collateral is
of a type customarily  sold in a recognized  market or is of a type which is the
subject of widely distributed  standard price quotations,  upon any such private
sale or sales,  to purchase the whole or any part of the Collateral so sold, and
thereafter to hold the same,  absolutely and free from any right or claim of any
kind. To the extent  permitted by applicable  law, the Debtor waives all claims,
damages  and  demands  against  the  Agent  arising  out  of  the   foreclosure,
repossession, retention or sale of the Collateral.

(b) Notice of Sale. Unless the Collateral threatens to decline speedily in value
or is of a type  customarily sold on a recognized  market,  the Agent shall give
the Debtor  ten (10)  days'  written  notice of its  intention  to make any such
public or private sale or sale at a broker's board or on a securities  exchange.
Such  notice  shall (i) in the case of a public  sale,  state the time and place
fixed  for  such  sale,  (ii) in the  case of sale at a  broker's  board or on a
securities  exchange,  state the board or  exchange  at which such sale is to be
made and the day on which the  Collateral,  or the portion  thereof  being sold,
will first be offered  for sale and (iii) in the case of a private  sale,  state
the day after which such sale may be consummated.  The Agent shall not obligated
to make any such sale  pursuant  to any such  notice.  The Agent may adjourn any
public or private  sale or cause the same to be  adjourned  from time to time by
announcement at the time and place fixed for the sale, and such sale may be made
at any time or place to which the same may be so  adjourned.  In the case of any
sale of all or any part of the Collateral on credit or for future delivery,  the
Collateral  so sold may be retained by the Agent until the selling price is paid
by the purchaser thereof, but the Agent shall not incur any liability in case of
the failure of such purchase to take up and pay for the  Collateral so sold and,
in the case of such failure, such Collateral may again be sold upon like notice.

(c) Special  Provisions  Relating to Sales of Securities.  The Debtor recognizes
that  the  Agent  may be  unable  to  effect  a  public  sale  of any or all the
Collateral  constituting a "security" (as such term is defined in the Securities
Act) by reason of  certain  prohibitions  contained  in the  Securities  Act and
applicable state securities laws or otherwise, and may be compelled to resort to
one or more private sales thereof to a restricted  group of purchasers that will
be obliged to agree,  among other things,  to acquire such  securities for their
own account for  investment  and not with a view to the  distribution  or resale
thereof.  The Debtor  acknowledges  and agrees  that any such  private  sale may
result in prices and other terms less  favorable than if such sale were a public
sale and, notwithstanding such circumstances,  agrees that any such private sale
shall be deemed to have been made in a commercially reasonable manner. The Agent
shall be under no obligation to delay a sale of any of Collateral constituting a
security  for the  period of time  necessary  to permit  the  issuer  thereof to
register  such  securities  for public sale under the  Securities  Act, or under
applicable state securities laws, even if such issuer would agree to do so.

Section 5.05.  Rights of Purchasers.  Upon any sale of the  Collateral  (whether
public or  private),  the Agent  shall  have the right to  deliver,  assign  and
transfer  to the  purchaser  thereof  the  Collateral  so sold.  Each  purchaser
(including  the  Agent)  at any such  sale  shall  hold the  Collateral  so sold
absolutely,  free from any claim or right of whatever kind, including any equity
or right of redemption of the Debtor who, to the extent permitted by law, hereby
specifically waives all rights of redemption, including, without limitation, any
right to redeem the Collateral  under Section 9-506 of the UCC, and any right to
a judicial or other stay or approval  which it has or may have under any law now
existing or hereafter adopted.

Section 5.06.     Additional Rights of the Agent.

(a) Right to Maintain Proceedings.  The Agent (i) shall have the right and power
to institute and maintain such suits and proceedings as it may deem  appropriate
to protect and enforce the rights  vested in it by this  Security  Agreement and
(ii) may proceed by suit or suits at law or in equity to enforce such rights and
to foreclose  upon the  Collateral and to sell all or, from time to time, any of
the   Collateral   under  the  judgment  or  decree  of  a  court  of  competent
jurisdiction.

(b)  Appointment  of  Receiver.  The Agent  shall,  to the extent  permitted  by
applicable law,  without notice to the Debtor to any party claiming  through the
Debtor,  without regard to the solvency or insolvency at such time of any Person
then liable for the  payment of any of the  Obligations,  without  regard to the
then value of the Collateral and without requiring any bond from any complainant
in such  proceedings,  be entitled as a matter of right to the  appointment of a
receiver  or  receivers  (who may be the  Agent) of the  Collateral  or any part
thereof,  pending  such  proceedings,  with such powers as the court making such
appointment  shall  confer,  and to the  entry  of an order  directing  that the
profits, revenues and other income of the property constituting the whole or any
part of the Collateral be segregated,  sequestered and impounded for the benefit
of the Agent,  and the Debtor  irrevocably  consents to the  appointment of such
receiver or receivers and to the entry of such order.

(c) No Duty to  Exercise  Rights.  In no event  shall the Agent have any duty to
exercise any rights or take any steps to preserve the rights of the Agent in the
Collateral,  nor shall the Agent be liable to the Debtor or any other Person for
any loss caused by the Agent's failure to meet any obligation imposed by Section
9-207 of the UCC or any successor provision. Without limiting the foregoing, the
Agent  shall be deemed to have  exercised  reasonable  care in the  custody  and
preservation  of the  Collateral in its possession if the Collateral is accorded
treatment  substantially equal to that which the Agent accords its own property,
it being understood that the Agent shall not have any duty or responsibility for
(i) ascertaining or taking action with respect to calls, conversions, exchanges,
maturities,  tenders or other matters relative to any Collateral, whether or not
the Agent has or is deemed to have knowledge of such matters, or (ii) taking any
necessary  steps to preserve  rights  against any  parties  with  respect to any
Collateral.

Section 5.07.     Remedies Not Exclusive, etc.

(a) Remedies Not Exclusive. No remedy conferred upon or reserved to the Agent in
this  Security  Agreement  is intended to be  exclusive  of any other  remedy or
remedies,  but every such remedy shall be cumulative and shall be in addition to
every other  remedy  conferred  herein or now or  hereafter  existing at law, in
equity or by statute.

(b)  Restoration  of Rights.  If the Agent shall have  proceeded  to enforce any
right,  remedy or power under this Security Agreement and the proceeding for the
enforcement  thereof shall have been discontinued or abandoned for any reason or
shall have been  determined  adversely  to the  Agent,  the Debtor and the Agent
shall,   subject  to  any  determination  in  such  proceeding,   severally  and
respectively  be  restored  to their  former  positions  and  rights  under this
Security Agreement,  and thereafter all rights, remedies and powers of the Agent
shall continue as though no such proceedings had been taken.

(c)  Enforcement.  All rights of action  under this  Security  Agreement  may be
enforced by the Agent without the  possession of any  instrument  evidencing any
Obligation or the production  thereof at any trial or other proceeding  relative
thereto, and any suit or proceeding  instituted by the Agent shall be brought in
its name and any judgment shall be held as part of the Collateral.

Section 5.08.     Waiver and Estoppel.

(a) No Actions to Impede Sale of Collateral. The Debtor agrees, to the extent it
may lawfully do so, that it will not at any time in any manner  whatsoever claim
or take the benefit or advantage of any appraisal,  valuation,  stay, extension,
moratorium,  turnover or redemption  law, or any law permitting it to direct the
order in which the  Collateral  shall be sold,  now or at any time  hereafter in
force  which  may  delay,   prevent  or  otherwise  affect  the  performance  or
enforcement  of this  Security  Agreement,  and  hereby  waives  all  benefit or
advantage of all such laws. The Debtor covenants that it will not hinder,  delay
or impede  the  execution  of any power  granted  to the Agent in this  Security
Agreement, any Assignment of Federal Contract or any other Credit Document.

(b) Collateral Sold As An Entirety. The Debtor, to the extent it may lawfully do
so, on behalf of itself and all who claim through or under it, including without
limitation any and all  subsequent  creditors,  vendees,  assignees and lienors,
waives  and  releases  all  rights to demand or to have any  marshalling  of the
Collateral upon any sale, whether made under any power of sale granted herein or
pursuant to judicial  proceedings or under any foreclosure or any enforcement of
this Security Agreement,  and consents and agrees that all of the Collateral may
at any such sale be offered and sold as an entirety.

(c) Waiver of  Notices.  The Debtor  waives,  to the  extent  permitted  by law,
presentment,  demand,  protest  and any notice of any kind  (except  the notices
expressly required hereunder) in connection with this Security Agreement and any
action taken by the Agent with respect to the Collateral.

Section 5.09.     Power of Attorney; Powers Coupled With An Interest.

(a) Power of Attorney.  Without limiting any other right granted hereunder,  the
Debtor hereby irrevocably constitutes and appoints the Agent, with full power of
substitution,  as its true and  lawful  attorney-in-fact  with full  irrevocable
power and  authority in the place and stead of the Debtor and in the name of the
Debtor  or in its  own  name,  from  time  to  time  in the  Agent's  reasonable
discretion,  for the  purpose  of  carrying  out  the  terms  of  this  Security
Agreement,  to take any and all  appropriate  action and to execute  any and all
documents and instruments  which may be necessary or desirable to accomplish the
purpose of this Security  Agreement and,  without limiting the generality of the
foregoing,  hereby gives the Agent the power and right, on behalf of the Debtor,
without notice to or assent by the Debtor, to do the following:

     (i)  to  pay  or  discharge  taxes,  liens,  security  interests  or  other
     encumbrances levied or placed on or threatened against the Collateral;

     (ii) to effect any repairs or any insurance called for by the terms of this
     Security Agreement or any other Credit Document, and to pay all or any part
     of the premiums therefor and the costs thereof;

     (iii) upon the  occurrence  and  continuance  of any Event of  Default  and
     otherwise to the extent provided in this Security Agreement,  (A) to direct
     any  party  liable  for any  payment  under any of the  Collateral  to make
     payment of any and all moneys due and to come due  thereunder  directly  to
     the Agent or as the Agent  shall  direct,  (B) to  receive  payment  of and
     receipt  for,  and to demand and sue for,  any and all  moneys,  claims and
     other  amounts  due and to become  due at any time in respect of or arising
     out of the Collateral,  (C) to sign and indorse and receive,  take,  assign
     and deliver,  any checks,  notes,  drafts,  negotiable  and  non-negotiable
     instruments,  any  invoices,  freight  or express  bills,  bills of lading,
     storage  or  warehouse  receipts,  drafts  against  debtors,   assignments,
     verifications  and notices in connection  with accounts and other documents
     relating to the Collateral, (D) to commence, settle, compromise,  compound,
     prosecute,  defend or adjust any claim,  suit,  action or  proceeding  with
     respect to, or in connection with, the Collateral,  (E) to sell,  transfer,
     assign or otherwise deal in or with the Collateral or any part thereof,  as
     fully and  effectively  as if the Agent were the absolute owner thereof and
     (F) to do, at its option,  but at the expense of the Debtor, at any time or
     from time to time,  all acts and things which the Agent deems  necessary to
     protect,  preserve or realize upon the Collateral and the Agent's  security
     interest therein, in order to effect the intent of this Security Agreement,
     all as fully and effectively as the Debtor might do.

(b) Powers Coupled With an Interest.  All authorizations and agencies granted or
provided  herein with respect to the  Collateral,  including the powers  granted
under clause (a) of this Section 5.9, are irrevocable and powers coupled with an
interest.

Section 5.10. Certain Provisions Relating to Securities.  Solely with respect to
any Collateral  constituting a "security" (as defined in the Securities Act), if
an Event of Default shall have occurred and be continuing,  all such  securities
(as defined in the Securities Act)  constituting a part of the Collateral shall,
at the  request  of the  Agent,  be  registered  in the name of the Agent or its
nominee,  and the Agent or its nominee may  thereafter  exercise (i) all voting,
corporate and other rights,  powers and privileges pertaining to such Collateral
at any meeting of shareholders of the issuer thereof or otherwise,  and (ii) any
and all  rights of  conversion,  exchange,  subscription  and any other  rights,
privileges or options  pertaining to such  Collateral as if it were the absolute
owner  thereof  (including,  without  limitation,  the right to  exchange at its
discretion  any  and  all  such  Collateral  upon  the  merger,   consolidation,
reorganization, recapitalization or other fundamental change in the structure of
any such  issuer,  or upon the exercise by the Debtor or the Agent of any right,
privilege or option pertaining to such Collateral,  and in connection therewith,
the right to deposit and deliver any and all such Collateral with any committee,
depositary, transfer agent, registrar or other designated agency upon such terms
and conditions as it may determine), all without liability except to account for
property  actually  received  by it and except as  provided  in  Section  5.6(c)
hereof,  but the Agent  shall  have no duty to the Debtor to  exercise  any such
right, privilege or option and shall not be responsible for any failure to do so
or delay in so doing.

     Section 5.11.  Application of Monies. The proceeds of any sale of, or other
     realization upon, all or any part of the Collateral shall be applied by the
     Agent in the following order of priority:

     first,  to  payment  of the  expenses  of such  sale or other  realization,
     including reasonable  compensation to the Agent and its agents and counsel,
     and all expenses,  liabilities and advances  incurred or made by the Agent,
     its agents and counsel in connection  therewith or in  connection  with the
     care, safekeeping or otherwise of any or all of the Collateral;

     second,  to  payment  of the  Obligations,  in such  order as the Agent may
     elect; and

     third,  any surplus  then  remaining  shall be paid to the  Debtor,  or its
     successors or assigns, or to whomsoever may be lawfully entitled to receive
     the same  (including  pursuant to Section  9-504(1)(C)  of the UCC) or as a
     court of competent jurisdiction may direct.

ARTICLE VI.

                                              MISCELLANEOUS

Section 6.01. Notices. All notices, requests and other communications to a party
hereunder  shall be in writing  and shall be given to such party at its  address
set forth on the  signature  page hereof or such other address as such party may
hereafter  specify for that  purpose by notice to the other.  Each such  notice,
request or other  communication shall be effective (i) in the case of telephonic
notice (to the extent  expressly  permitted  hereunder),  when made, (ii) in the
case of notice delivered by overnight  express  courier,  one Business Day after
the Business Day such notice was delivered to such courier, (iii) in the case of
notice  delivered by first class mail, three Business Days after being deposited
in the mail,  postage  prepaid,  return receipt  requested,  (iv) in the case of
notice by hand,  when  delivered,  or (v) in the case of notice by any customary
means of telecommunication, when sent provided confirmation of receipt or answer
back has been  received,  in each  case if  addressed  to any  party  hereto  as
provided  herein.  Rejection or refusal to accept,  or the  inability to deliver
because of a changed address of which no notice was given,  shall not affect the
validity of notice given in accordance with this section.

Section 6.02.  No Waiver;  Cumulative  Remedies.  The Agent shall not by any act
(except by a written  instrument  pursuant  to Section  6.3 hereof) be deemed to
have waived any right or remedy hereunder. No failure to exercise, nor any delay
in exercising,  on the part of the Agent any right, power or privilege hereunder
shall operate as a waiver thereof.  No single or partial  exercise of any right,
power or  privilege  hereunder  shall  preclude  any other or  further  exercise
thereof or the exercise of any other right, power or privilege.  A waiver by the
Agent  of any  right  or  remedy  hereunder  on any one  occasion  shall  not be
construed as a bar to any right or remedy which the Agent would  otherwise  have
on any future occasion.  The rights and remedies herein provided are cumulative,
may be  exercised  singly or  concurrently  and are not  exclusive  of any other
rights or remedies provided by law.

Section 6.03.  Amendments  and Waivers.  None of the terms or provisions of this
Security Agreement may be amended,  supplemented or otherwise modified except by
a written  instrument  executed by the Debtor and the Agent;  provided  that any
provision of this  Security  Agreement may be waived by the Agent in a letter or
agreement  executed by the Agent or by telex or facsimile  transmission from the
Agent.

Section 6.04.  Successors and Assigns. The provisions of this Security Agreement
shall be binding  upon and inure to the benefit of the parties  hereto and their
respective  successors and assigns;  provided,  however, that the Debtor may not
assign or transfer any of its rights or obligations  hereunder without the prior
written consent of the Agent.

     Section 6.05.  Governing Law. THIS SECURITY  AGREEMENT SHALL BE GOVERNED BY
     AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE  COMMONWEALTH OF VIRGINIA,
     OTHER THAN ITS LAWS RESPECTING  CHOICE OF LAW OTHER THAN THOSE CONTAINED IN
     THE UCC.

Section 6.06.     Limitation by Law; Severability.

(a) All rights,  remedies and powers provided in this Security  Agreement may be
exercised  only to the extent  that the  exercise  thereof  does not violate any
applicable  provision of law, and all the provisions of this Security  Agreement
are intended to be subject to all applicable  mandatory  provisions of law which
may be controlling  and to be limited to the extent  necessary so that they will
not render this Security Agreement  invalid,  unenforceable in whole or in part,
or not entitled to be recorded,  registered or filed upon the  provisions of any
applicable law.

(b) If any provision hereof is invalid and  unenforceable  in any  jurisdiction,
then, to the fullest extent  permitted by law, (i) the other  provisions  hereof
shall  remain  in full  force  and  effect  in such  jurisdiction  and  shall be
liberally  construed in favor of the Agent in order to carry out the  intentions
of the parties  hereto as nearly as may be possible and (ii) the  invalidity  or
unenforceability  of any provision hereof in any  jurisdiction  shall not affect
the validity or enforceability of such provision in any other jurisdiction.

Section  6.07.  Counterparts.  This  Security  Agreement  may be executed in any
number of counterparts and by different parties hereto on separate counterparts,
each complete set of which, when so executed and delivered by all parties, shall
be an original,  but all such counterparts shall together constitute but one and
the same instrument.

Section 6.08. Expenses of the Agent. The Debtor shall pay to the Agent from time
to time upon demand,  all of the costs and expenses incurred by the Agent or any
Lender (including,  without limitation, the reasonable fees and disbursements of
counsel  and any  amounts  payable  by the  Agent or any  Lender to any of their

                               Security Agreement

                                          ASSIGNMENT OF FEDERAL CONTRACT


                  This  ASSIGNMENT OF FEDERAL  CONTRACT,  dated as of _____,  __
(the "Agreement"),  is made by HAGLER BAILLY,  INC., a Delaware corporation (the
"Assignor"), in favor of NATIONSBANK,  N.A., a national banking association (the
"Agent"),  in its capacity as Agent for the lenders from time to time a party to
the Revolving Credit Agreement (as defined in the Security Agreement referred to

                                               W I T N E S S E T H:

                  WHEREAS,   the  Assignor  has  secured   certain   obligations
undertaken by it pursuant to the provisions of a Security Agreement, dated as of
___________________, ____ (as the same may be amended, supplemented or otherwise
modified  from time to time,  the  "Security  Agreement"),  by and  between  the
Assignor and the Agent; and

                  WHEREAS,  the  Assignor  is a party to,  and from time to time
will  become  entitled  to  receive  moneys  under and by  virtue  of, a certain
contract  with,  involving or for the benefit of the United States of America or
any department,  agency or  instrumentality  thereof (herein  referred to as the

Assignor and the Government on ________ __, 19__ (which contract,  together with
all additions, change orders, supplements, amendments, renewals, extensions, and
modifications  thereto now or hereafter in effect, are hereinafter  collectively
called the "Contract"); and

                  WHEREAS,  pursuant to the Security Agreement, the Assignor has
undertaken to effectuate the  assignment(s)  and other actions  contemplated  by
this Agreement.

                  NOW,  THEREFORE,  in  consideration  of the premises and other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the Assignor covenants and agrees as follows:

         1. Incorporation By Reference. The provisions of the Security Agreement
are  incorporated  herein by  reference,  and the terms  defined in the Security
Agreement are used herein with the same meanings.

         2.  Representations.  The Assignor represents and warrants to the Agent
that (a) the Contract is legal,  valid and binding on the  Assignor  and, to its
knowledge,  the other parties thereto,  is in full force and effect,  and is not
evidenced  by any  chattel  paper or  instrument,  (b) upon due  filing  of this
Agreement,  together  with a Notice of Assignment  substantially  in the form of
Appendix A hereto with the authorized representative, the execution and delivery
of this Agreement does not violate and is not in conflict with the provisions of
the  Contract,  (c) there has been no default on the part of the Assignor or any
other party to the Contract, (d) the Assignor has made no previous assignment of
the  Contract to any person and knows of no fact or defense that will render the
moneys due or to be due  thereunder  uncollectible,  (e) no financing  statement
covering  the  Contract  is on  file  in  any  public  office  except  financing
statements in favor of the Agent,  (f) no set-off or  counterclaim to any moneys
due or to become  due  under the  Contract  exists  on the date  hereof,  and no
agreement  has been made with any person  under which any  deduction or discount
may be claimed,  and (g) the address of the office where the Assignor  keeps its
records concerning the Contract is ____________________.

         3. Collateral. As security and collateral for the payment of all of the
Obligations  (defined in the Security  Agreement)  and for  performance  of, and
compliance  with,  by the  Assignor,  all of the terms,  covenants,  conditions,
stipulations,  and  agreements  contained in this  Agreement and in the Security
Agreement,  the Assignor hereby assigns to the Agent,  and grants to the Agent a
lien on and  security  interest  in,  all  moneys  and claims for moneys now and
hereafter  due and to  become  due to the  Assignor  under or by  reason  of the
Contract,  together  with all  cash and  non-cash  proceeds  thereof;  provided,
however,  that nothing  contained  herein shall impose upon the Agent any of the
obligations or liabilities of the Assignor under the Contract.

         4. Covenants. Until payment and performance in full of the Obligations,
the Assignor covenants as follows:

(c) The  Assignor  shall  place  on any and all  vouchers,  invoices,  or  other
instruments demanding payment under the Contract the direction that such payment
is to be made to the Agent in accordance with Section 5 of this Agreement.

(d) The Assignor shall promptly upon request execute,  acknowledge,  and deliver
any  notice,  financing  statement,   renewal,   affidavit,   deed,  assignment,
continuation statement,  security agreement,  certificate,  or other document as
the  Agent  may  require  in  order to  perfect,  preserve,  maintain,  protect,
continue, and/or extend the assignment, lien, and security interest of the Agent
under this  Agreement and its priority.  The Assignor  shall pay to the Agent on
demand all taxes,  costs, and expenses  incurred by the Agent in connection with
the  preparation,  execution,  recording,  and  filing of any such  document  or
instrument  mentioned  aforesaid,  and such taxes,  costs,  and  expenses  shall
constitute  and become a part of the  Obligations.  A carbon,  photographic,  or
other  reproduction  of  a  security  agreement  or  a  financing  statement  is
sufficient as a financing statement.

(e) The Assignor shall fully,  promptly,  and faithfully comply with and perform
its  obligations  and duties  under the  Contract in  accordance  with the terms
thereof and will make no changes or  amendments  to the Contract or terminate or
cancel the  Contract  without the prior  written  consent of the Agent except as
permitted by the Security  Agreement.  In the event that any change,  amendment,
termination  or  cancellation  of  the  Contract  is  made  or  effected  by the
Government,  the Assignor  will  promptly  notify the Agent thereof and promptly
furnish to the Agent a copy of any  document or  agreement  evidencing  any such
change, amendment, termination, or cancellation.

(f)      The Assignor will promptly

     (i) furnish to the Agent all information received by the Assignor affecting
     the moneys due and to become due under the Contract,

     (ii)  inform the Agent of any delay in  performance  of, or claims  made in
     regard to, the Contract, and

(iii) notify the Agent in writing of the failure of any party to the Contract to
perform any of its  obligations  thereunder and any rejection of any performance
rendered by the Assignor under or in connection with the Contract.

(g) The  Assignor  will at all times  keep  accurate  and  complete  records  of
performance  by the Assignor  under the  Contract,  and the Agent and its agents
shall have the right,  during normal business hours and upon reasonable  advance
notice,  to call at the place or places of business of the Assignor at intervals
to be  determined  by the Agent,  and without  hindrance  or delay,  to inspect,
audit,  check,  and make extracts  from the books,  records,  journals,  orders,
receipts,  correspondence,  and other data  relating  to the  Contract or to any
other transactions between the parties hereto related to the Contract.

         5. Payments. The Assignor hereby authorizes,  empowers, and directs the
Government to draw all checks,  drafts,  or other  instruments  representing the
payments of money due the Assignor under the Contract  (herein called the "Items
of Payment") to the order of  NationsBank,  N.A.,  assignee of Assignor,  and to
send  the  same  (i)  if by  mail,  to ,  (ii)  if by  electronic  transfer,  to
NationsBank, N.A. for the account of ________________, Bank Account #__________,
Agent ABA#_________,  or (iii) if by wire transfer, to NationsBank, N.A. for the
account of  _________________________,  Bank Account #_______,  ABA#___________.
If, despite this  direction,  any  instruments or checks  representing  payments
should be delivered to the Assignor,  the Assignor will immediately  endorse and
deliver such  instruments or checks to the order of the Agent. The Assignor does
hereby  irrevocably  (subject  to  revocation  with the  consent  of the  Agent)
designate and appoint (which appointment is coupled with an interest) the Agent,
and the Agent's  successors in interest by operation of law, the Assignor's true
and  lawful  attorney  with  power  irrevocable  for  the  Assignor  and  in the
Assignor's  name,  place,  and  stead,  but at the sole cost and  expense of the
Assignor,  to receive,  endorse,  and collect all Items of Payment,  and to ask,
demand,  receive,  receipt,  and give acquittances for any and all amounts which
may be payable  or which  become due and  payable  by the  Government  under the
Contract,  and in the Agent's  discretion to file any claim or to take any other
action  or  proceeding,  either  in the  Agent's  own name or in the name of the
Assignor or otherwise,  which to the Agent or any successor in interest  thereof
may seem  necessary  or  desirable in order to collect or endorse the payment of
any and all amounts now due or owing or which may  hereafter be or become due or
owing on account of the  Contract.  All Items of Payment  received  by the Agent
pursuant  hereto  which are  finally  paid in cash or solvent  credits  shall be
applied  against the  Obligations  as provided in the  Security  Agreement.  Any
portion of the Items of Payment  which the Agent elects not to so apply shall be
paid over to the  Assignor  or to  whomsoever  shall be entitled  thereto  under
applicable  law,  including  pursuant  to  Section  9-504(1)(C)  of the  Uniform
Commercial Code of the Commonwealth of Virginia.

         6.  No  Waiver.   Neither  this  Agreement  nor  any  term,  condition,
representation,  warranty, covenant, or agreement hereof may be changed, waived,
discharged,  or terminated  orally,  but only by an instrument in writing by the
party against whom such change, waiver, discharge, or termination is sought.

         7. Governing law. THIS AGREEMENT  SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE  WITH THE LAWS OF THE  COMMONWEALTH  OF VIRGINIA,  WITHOUT  REGARD TO
PRINCIPLES OF CONFLICTS OF LAWS.

         8. Gender.  Whenever used herein, the singular number shall include the
plural,  the plural the singular,  and the use of the  masculine,  feminine,  or
neuter gender shall include all genders.

         9.  Counterparts.  This  Agreement  may be  executed  in any  number of
duplicate  originals,  each of  which  shall  be an  original  but all of  which
together shall constitute one and the same instrument.

         10. Paragraph  Headings.  The paragraph  headings of this Agreement are
for  convenience  only and  shall not limit or  define  the  provisions  of this
Agreement.

ARTICLE VIII.

                                            SECURITY INTERESTS

Section  8.01.  Grant of  Security  Interests.  To secure  the due and  punctual
payment of all Obligations,  howsoever  created,  arising or evidenced,  whether
direct or indirect,  absolute or contingent, now or hereafter existing or due or
to become  due,  whether at  maturity  or upon  acceleration  or  otherwise,  in
accordance with the terms thereof and to secure the due and punctual performance
of all of the  Obligations  and in order to induce the Agent and the  Lenders to
enter into the Revolving  Credit Agreement and the other Credit  Documents,  the
Debtor hereby pledges,  assigns,  delivers,  conveys and transfers to the Agent,
for the ratable benefit of the Lenders, and grants to the Agent, for the ratable
benefit of the Lenders, a first priority and continuing security interest in and
lien on, all of the  Debtor's  right,  title and  interest  in, to and under the
following, whether now existing or hereafter acquired (the "Collateral"):

(i)      all Receivables;

(ii)     all Other Intangibles;

(iii)    all Equipment;

(iv)     all Inventory;

(v) to the  extent  not  included  in the  foregoing,  all  securities  (whether
certificated or uncertificated)  and all financial assets,  whether now existing
or hereafter arising, including, without limitation, all capital stock issued by
any Person and held by Debtor,  and all  partnership  interests,  whether in the
nature of a joint venture,  limited liability company member's interest,  master
limited partnership, teaming arrangement or otherwise;

(vi) to the extent not included in the foregoing,  all other personal  property,
whether  tangible or intangible,  and wherever located whether within or outside
of the United  States,  including,  but not  limited  to,  the  balance of every
deposit  account now or hereafter  existing of the Debtor with any bank or other
financial  institution and all monies of the Debtor and all rights to payment of
money of the Debtor;

(vii) to the extent not  included  in the  foregoing,  all  books,  ledgers  and
records and all computer  programs,  tapes,  discs, punch cards, data processing
software,  transaction  files,  master  files and  related  property  and rights
(including computer and peripheral equipment) necessary or helpful in enforcing,
identifying or establishing any item of Collateral; and

(viii) to the extent not otherwise included, all Proceeds and products of any or
all of the foregoing, whether existing on the date hereof or arising hereafter;

provided,  however,  notwithstanding  anything to the contrary contained herein,
the  Debtor is not  assigning,  pledging  or  otherwise  encumbering  under this
Security Agreement its interests in any Federal Contract to which it is a party,
or in accounts or receivables due to Debtor under such Federal Contract,  to the
extent,  but only to the extent,  such assignment,  pledge or other  encumbrance
would  breach or violate or would cause Debtor to breach or violate such Federal
Contract or statutes or regulations applicable thereto, it being understood that
this proviso does not apply to, or in any way limit, Debtor's assignment, pledge
or encumbrance of Proceeds of all Federal Contracts to which it is a party.

Section  8.02.  Continuing  Liability  of the  Debtor.  Anything  herein  to the
contrary notwithstanding,  the Debtor shall remain liable to observe and perform
all the  terms and  conditions  to be  observed  and  performed  by it under any
contract,   agreement,   warranty  or  other  obligation  with  respect  to  the
Collateral;  and  shall do  nothing  to impair  the  security  interests  herein
granted.  The Agent shall not have any  obligation  or liability  under any such
contract,  agreement, warranty or obligation by reason of or arising out of this
Security  Agreement  or the receipt by the Agent of any payment  relating to any
Collateral,  nor shall the Agent be  required  to perform or fulfill  any of the
obligations of the Debtor with respect to the Collateral, to make any inquiry as
to the nature or sufficiency of any payment received by it or the sufficiency of
the  performance  of any party's  obligations  with  respect to any  Collateral.
Furthermore,  the  Agent  shall not be  required  to file any claim or demand to
collect any amount due or to enforce the performance of any party's  obligations
with respect to, the Collateral.

Section 8.03.     Sales and Collections.

(a) Sales of  Inventory  in the  Ordinary  Course  of  Business.  The  Debtor is
authorized (i) to sell in the ordinary course of its business for fair value and
on an  arm's-length  basis  any of its  Inventory  normally  held by it for such
purpose and (ii) to use and consume, in the ordinary course of its business, any
raw materials,  supplies and materials normally held by it for such purpose. The
Agent may, upon the occurrence of any Event of Default, without cause or notice,
curtail or terminate such authority at any time.

(b) Collection of Receivables. The Debtor is authorized to collect amounts owing
to it with respect to the Collateral, except as otherwise provided in connection
with the Assignment of Federal Contract, if any as provided herein. However, the
Agent may, upon and during the continuance of an Event of Default or a Potential
Event of Default, notify Account Debtors obligated to make payments under any or
all Receivables or Other  Intangibles that the Agent has a security  interest in
such Collateral and that payments shall be made directly to the Agent.  Upon the
request of the Agent upon and during the continuance of an Event of Default or a
Potential  Event of Default,  as the case may be, the Debtor will so notify such
Account  Debtors  and  will  execute  such  contract  assignments,   notices  of
assignment or other  documents as may be required by such Account  Debtors.  The
Debtor will use all  reasonable  efforts to cause each Account  Debtor to comply
with the foregoing  instruction.  In furtherance  of the  foregoing,  the Debtor
authorizes the Agent upon and during the continuance of an Event of Default or a
Potential  Event of Default (i) to ask for,  demand,  collect,  receive and give
acquittances  and  receipts  for any and all amounts due and to become due under
any Collateral and in the name of the Debtor or its own name or otherwise,  (ii)
to  take  possession  of,  endorse  and  collect  any  checks,   drafts,  notes,
acceptances  or other  instruments  for the  payment  of  monies  due  under any
Collateral  and (iii) to file any claim or take any other action in any court of
law or equity or  otherwise  which it may deem  appropriate  for the  purpose of
collecting  any  amounts  due under any  Collateral.  The  Agent  shall  have no
obligation  to obtain or record any  information  relating to the source of such
funds or the obligations in respect of which payments have been made.

Section 8.04.     Segregation of Proceeds.

(a) Cash Collateral  Account  Maintained by Agent. Upon an Event of Default or a
Potential  Event of  Default,  the Agent shall have the right at any time during
the  continuance  thereof to cause to be opened and  maintained at the office of
the Agent in McLean,  Virginia a  non-interest  bearing  bank account (the "Cash
Collateral  Account") which will contain only Proceeds.  Any "cash proceeds" (as
such term is defined  in  Section  9-306(1)  of the UCC)  received  by the Agent
directly from Account  Debtors  obligated to make payments under  Receivables or
Other Intangibles  pursuant to Section 2.3 hereof or from the Debtor pursuant to
clause (b) of this Section 2.4,  whether  consisting of checks,  notes,  drafts,
bills of exchange, money orders,  commercial paper or other Proceeds received on
account of any  Collateral,  shall be promptly  deposited in the Cash Collateral
Account, and until so deposited shall be held in trust for the Agent as property
of the  Agent  and shall not be  commingled  with any  funds of the  Debtor  not
constituting  Proceeds  of  Collateral.  The name in which  the Cash  Collateral
Account is carried shall clearly  indicate that the funds deposited  therein are
the  property  of the  Debtor,  subject to the  security  interest  of the Agent
hereunder. Such Proceeds, when deposited,  shall continue to be security for the
Obligations   and  shall  not  constitute   payment  thereof  until  applied  as
hereinafter  provided.  The Agent shall have sole  dominion and control over the
funds deposited in the Cash Collateral Account,  and such funds may be withdrawn
therefrom only by the Agent.

(b) Deposit of  Proceeds  by the Debtor.  Upon notice by the Agent to the Debtor
that the Cash  Collateral  Account has been  opened,  the Debtor shall cause all
cash  Proceeds  collected  by it to be  delivered  to the Agent  forthwith  upon
receipt,  in the original  form in which  received  (with such  endorsements  or
assignments as may be necessary to permit collection  thereof by the Agent), and
for such  purpose the Debtor  hereby  irrevocably  authorizes  and  empowers the
Agent,  its officers,  employees and  authorized  agents to endorse and sign the
name of the Debtor on all checks, drafts, money orders or other media of payment
so delivered,  and such endorsements or assignments shall, for all purposes,  be
deemed to have been made by the Debtor prior to any  endorsement  or  assignment
thereof by the Agent.  The Agent may use any  convenient or customary  means for
the purpose of collecting  such checks,  drafts,  money orders or other media of
payment.

Section 8.05.  Verification  of  Receivables.  The Agent shall have the right to
make test  verifications of Receivables in any reasonable manner and through any
medium that it considers  advisable,  and the Debtor  agrees to furnish all such
assistance and  information  as the Agent may  reasonable  require in connection
therewith.  The Debtor at its expense will cause its chief financial  officer to
furnish to the Agent at any reasonable  time and from time to time promptly upon
the Agent's reasonable request,  the following reports:  (i) a reconciliation of
all Receivables, (ii) an aging of all Receivables, (iii) trial balances and (iv)
a test verification of such Receivables as the Agent may request.

Section 8.06.     Release of Collateral.

(a) Security  Interest of Agent Ceases Upon Permitted  Dispositions.  The Debtor
may sell or realize upon or transfer or otherwise  dispose of Collateral only to
the extent permitted by Section 4.13, and the security interests of the Agent in
such  Collateral so sold,  realized upon or disposed of (but not in the Proceeds
arising from such sale, realization or disposition) shall cease immediately upon
such sale, realization or disposition, without any further action on the part of
the Agent.  The Agent,  if requested in writing by the Debtor but at the expense
of the Debtor,  is hereby  authorized  and  instructed to deliver to the Account
Debtor or the purchaser or other transferee of any such Collateral a certificate
stating  that the Agent no longer  has a  security  interest  therein,  and such
Account Debtor or such purchaser or other  transferee  shall be entitled to rely
conclusively on such certificate for any and all purposes.

(b) Filing of  Termination  Statements.  Upon the  payment in full of all of the
Obligations  and if  there  is no  commitment  by any  Lender  to  make  further
advances,  incur obligations or otherwise give value, the Agent will (as soon as
reasonably  practicable  after receipt of notice from the Debtor  requesting the
same but at the  expense  of the  Debtor)  deliver  to the  Debtor  (i) for each
jurisdiction  in  which a UCC  financing  statement  is on file to  perfect  the
security  interests  granted to the Agent  hereunder,  a  termination  statement
(appropriately  completed)  to the  effect  that the  Agent no  longer  claims a
security interest under such financing statement,  and (ii) such other documents
as  the  Debtor  shall  reasonably  request   evidencing   satisfaction  of  the
Obligations  and the  release  of the  security  interests  granted to the Agent
hereunder.



ARTICLE IX.

                                      REPRESENTATIONS AND WARRANTIES

         The Debtor represents and warrants that:

Section 9.01. Title to Collateral.  Except for the security interests granted to
the Agent  pursuant to this  Security  Agreement  and as otherwise  permitted by
Section 6.2(a) of the Revolving Credit  Agreement,  the Debtor is the sole owner
of each item of the Collateral,  having good and marketable title thereto,  free
and clear of any and all Liens.

Section 9.02.     Validity, Perfection and Priority of Security Interests.

(a) By complying  with Section 4.1 hereof,  the Debtor will have created a valid
security  interest in favor of the Agent in all existing  Collateral  and in all
identifiable  Proceeds of such  Collateral,  which security  interest (except in
respect of  Collateral  not located at a facility  identified  on  Schedule  3.7
hereto  and motor  vehicles  for  which the  exclusive  manner of  perfecting  a
security interest therein is by noting such security interest in the certificate
of title in accordance with local law) would be prior to the claims of a trustee
in bankruptcy under Section 544(a) of the Bankruptcy Code. Continuing compliance
by the Debtor  with the  provisions  of Section  4.2 hereof will also (i) create
valid security interests in all Collateral acquired after the date hereof and in
all  identifiable  Proceeds  of such  Collateral  and (ii) cause  such  security
interests in all Collateral and in all Proceeds which are (A) identifiable  cash
Proceeds of  Collateral  covered by  financing  statements  required to be filed
hereunder,  (B)  identifiable  Proceeds  in  which a  security  interest  may be
perfected  by such  filing  under  the UCC and  (C)  any  Proceeds  in the  Cash
Collateral Account to be duly perfected under the UCC, in each case prior to the
claims of a trustee in bankruptcy  under the Bankruptcy  Code (except in respect
of Collateral not located at a facility identified on Schedule 3.5 hereto).

(b) The  security  interests  of the  Agent  in the  Collateral  located  at the
facilities identified on Schedule 3.5 hereto rank first in priority.  Other than
financing   statements  or  other  similar  documents  perfecting  the  security
interests  in favor of the  Agent,  no  financing  statements,  deeds of  trust,
mortgages or similar documents covering all or any part of the Collateral are on
file or of record in any  government  office in any  jurisdiction  in which such
filing or recording  would be  effective to perfect a security  interest in such
Collateral,  nor is any of the Collateral in the possession of any Person (other
than the Debtor) asserting any claim thereto or security interest therein.

Section 9.03.  Enforceability of Receivables and Other Intangibles.  To the best
knowledge of the Debtor,  each  Receivable  and Other  Intangible is a valid and
binding obligation of the related Account Debtor in respect thereof, enforceable
in accordance with its terms,  except as such  enforceability  may be limited by
applicable bankruptcy,  insolvency,  reorganization,  moratorium or similar laws
affecting  the  enforcement  of  creditors'  rights  generally  and  by  general
provisions of equity (regardless of whether such enforceability is considered in
a  proceeding  in equity or at law),  and  complies  with any  applicable  legal
requirements.

Section 9.04.  Place of Business.  Schedule 3.4  correctly  sets forth the chief
executive  office and principal  place of business of the Debtor and the offices
of the Debtor where records  concerning  Receivables  and Other  Intangibles are
kept.

Section 9.05.  Location of  Collateral.  Schedule 3.5  correctly  sets forth the
location of all Equipment and Inventory,  other than rolling stock, aircraft and
goods in transit.  Except as otherwise  specified in Schedule 3.5, all Inventory
and Equipment  has been located at the address  specified on Schedule 3.5 at all
times during the  four-month  period prior to the date hereof while owned by the
Debtor.  All Inventory has been and will be produced in compliance with the Fair
Labor Standards Act, 29 U.S.C.  ss.ss.  201-219,  except for such non-compliance
which could not reasonably be expected to have a material  adverse effect on the
Debtor. No Inventory is evidenced by a negotiable  document of title,  warehouse
receipt  or bill of  lading.  No  non-negotiable  document  of title,  warehouse
receipt or bill of lading has been  issued to any person  other than the Debtor,
and the Debtor has retained possession of all of such non-negotiable  documents,
warehouse receipts and bills of lading. No amount payable under or in connection
with  any  of  the  Collateral  is  evidenced  by  promissory   notes  or  other
instruments.

Section 9.06.  Trade Names.  Schedule 3.6 correctly sets forth any and all trade
names,  division  names,  assumed  names or other  names  under which the Debtor
currently  transacts  business or has transacted  business within the four-month
period prior to the date hereof.

     Section 9.07. Patents and Trademarks. Schedule 3.7 correctly sets forth all
     Patents,  Patent licenses,  Trademarks and Trademark  licenses now owned by
     the Debtor.

ARTICLE X.

                                                COVENANTS

                  The Debtor covenants and agrees that until all obligations and
liabilities in respect of the Obligations  shall have performed and paid in full
and  until  no  Standby   Letters  of  Credit  are  outstanding  or  fully  cash
collateralized and the Commitments are terminated:

Section  10.01.  Perfection  of  Security  Interests.  The Debtor  will,  at its
expense,  cause all  filings  and  recordings  and other  actions  specified  on
Schedule 4.1 to have been completed on or prior to the Effective Date.

Section 10.02.    Further Actions.

(a) At all times after the date hereof, the Debtor will, at its expense,  comply
with the following:

(i) as to all Receivables,  Other Intangibles,  Equipment and Inventory, it will
cause UCC financing statements and continuation statements to be filed and to be
on file in all  applicable  jurisdictions  as required  to perfect the  security
interests  granted to the Agent  hereunder,  to the extent that  applicable  law
permits perfection of a security interest by filing under the UCC;

(ii)  as to all  Proceeds,  it  will  cause  all UCC  financing  statements  and
continuation  statements  filed in accordance with clause (i) above to include a
statement or a checked box  indicating  that Proceeds of all items of Collateral
described herein are covered;

(iii) as to any amount payable under or in connection with any of the Collateral
which  shall  be or  shall  become  evidenced  by any  promissory  note or other
instrument,  the  Debtor  will  promptly  (but in no event  later  than ten (10)
Business Days after receipt of such note or instrument), pledge and deliver such
note or other  instrument to the Agent as part of the Collateral,  duly endorsed
in a manner reasonably satisfactory to the Agent;

(iv) at the request of the Agent,  the Debtor shall deliver all other Collateral
consisting  of  certificated  securities,  endorsed  for  transfer  in a  manner
reasonably  satisfactory  to the Agent (or  execute  a  securities  intermediary
account  control  agreement  to the  extent  possession  by the  Agent  of  such
securities is not feasible); and

(v) as to all Patents,  Patent licenses,  Trademarks or Trademark licenses,  the
Debtor will effect the recordation or renewal of the recordation of the security
interests of the Agent therein so as to maintain  valid and  perfected  security
interests therein under all applicable state and federal laws.

(b) Further  Assurances.  The Debtor will, from time to time and at its expense,
execute, deliver, file or record such UCC financing statements, applications for
certificates  of title  and such  other  statements,  assignments,  instruments,
documents,  agreements  or other  papers and take any other  action  that may be
necessary or desirable,  or that the Agent may reasonably  request,  in order to
create,  preserve,  perfect,  confirm or validate the  security  interest of the
Agent in the Collateral, to enable the Agent to obtain the full benefits of this
Security  Agreement  or to enable it to exercise  and enforce any of its rights,
powers and remedies hereunder,  including, without limitation, its right to take

Agent to sign and file  financing and  continuation  statements  and  amendments
thereto with respect to the Collateral without its signature thereon.

its name, identity or corporate structure in any manner and, except as set forth
on  Schedule  3.6,  will not conduct its  business  under any trade,  assumed or
fictitious  name unless it shall have given the Agent at least  forty-five  (45)
days'  prior  written  notice  thereof  and shall have taken all action (or made
arrangements to take such action  substantially  simultaneously with such change
if it is  impossible  to take such action in advance)  necessary  or  reasonably
requested  by the  Agent  to  amend  any  financing  statement  or  continuation

advance of such change,  makes all UCC filings required by Section 4.2 and takes
all other action necessary or that the Agent may reasonably request to preserve,
perfect,  confirm and protect the security  interests granted hereby. The Debtor
will in no event  change the  location of any  Collateral  if such change  would
cause the security  interest granted hereby in such Collateral to lapse or cease
to be  perfected.  The Debtor  will at all times  maintain  its chief  executive

to effectuate or maintain the priority  thereof  against all Persons;  provided,
however,  that,  so long as no Event of  Default or  Potential  Event of Default
shall have  occurred  and be  continuing,  the Debtor  shall not be obligated to
comply with the provisions of this Section 4.5 with respect to the first $50,000
of Equipment (determined based on the then fair market value thereof).

Section 10.06.  Maintenance of Records. The Debtor will keep and maintain at its
own cost and expense complete books and records relating to the Collateral which
are satisfactory to the Agent  including,  without  limitation,  a record of all
payments received and all credits granted with respect to the Collateral and all
of its other  dealings with the  Collateral.  The Debtor will mark its books and
records pertaining to the Collateral to evidence this Security Agreement and the
security interests granted hereby.  For the Agent' further security,  the Debtor
agrees  that the Agent  shall  have a special  property  interest  in all of the

respects with all acts, rules,  regulations,  orders,  decrees and directions of
any government or any state or local government  applicable to the Collateral or
any part  thereof or to the  operation of the  Debtor's  business  except to the
extent that the failure to comply  would not have a material  adverse  effect on
the  financial or other  condition of the Debtor;  provided,  however,  that the
Debtor may contest any act, rule, regulation,  order, decree or direction in any
reasonable  manner which shall not, in the sole opinion of the Agent,  adversely
affect the Agent's  rights or, in the case of  Collateral  located at a facility
identified on Schedule 3.7 hereto,  the first priority of its security  interest
in the Collateral.

Section  10.08.  Payment of Taxes.  The Debtor  will pay  promptly  when due all
taxes,   assessments  and  governmental  charges  or  levies  imposed  upon  the
Collateral  or in respect of its  income or  profits  therefrom,  as well as all
claims of any kind (including claims for labor, materials and supplies),  except
that no such charge need be paid if (i) the validity  thereof is being contested
in good faith by  appropriate  proceedings  and (ii) such  charge is  adequately
reserved against in accordance with generally accepted accounting principles, as
consistently applied.

Section 10.09. Compliance with Terms of Accounts and Contracts.  The Debtor will
perform and comply in all material  respects with all of its  obligations  under
all agreements  relating to the Collateral to which it is a party or by which it
is bound.

permit or suffer to exist,  and will  defend  the  Collateral  and the  Debtor's
rights with respect  thereto  against and take such other action as is necessary
to  remove  any  Lien,  security  interest,  encumbrance,  or claim in or to the

Intangibles;  No Waivers or Extensions.  The Debtor will not (i) amend,  modify,
terminate or waive any provisions of any material Receivable or Other Intangible

Receivables or Other Intangibles,  respectively, in the Collateral, (ii) fail to
exercise promptly and diligently each and every material right which it may have

the Revolving Credit Agreement.

Section 10.13.  Limitations on Dispositions  of Collateral.  The Debtor will not

the prior  written  consent of the Agent,  sell,  transfer,  lease or  otherwise
dispose of any of the Collateral,  or attempt, offer or contract to do so except

Potential  Event of Default) has occurred and is continuing,  dispositions  in a

as the  proceeds  of any such  disposition  are (x) used to acquire  replacement
equipment  which has comparable or better utility and equivalent or better value
and which is subject to a first priority security interest in favor of the Agent
therein,  except  as  permitted  by  Section  6.2(a)  of  the  Revolving  Credit
Agreement, or (y) applied to repay the Obligations. The inclusion of Proceeds of

permitted by this Section 4.13.

Section 10.14. Further Identification of Collateral.  The Debtor will furnish to
the Agent from time to time  statements and schedules  further  identifying  and

the Agent if the value of the Collateral located at the facilities identified on
Schedule 3.7 hereto is less than 80% of the value of all of the Collateral.

Section  10.15.  Notices.  The  Debtor  will  advise the Agent  promptly  and in
reasonable detail (i) of any Lien, security interest,  encumbrance or claim made
or  asserted  against  any of the  Collateral,  other  than,  unless  reasonably
requested  by the Agent,  Liens  permitted  by Section  6.2(a) of the  Revolving
Credit  Agreement,  (ii)  of  any  material  change  in the  composition  of the
Collateral,  and (iii) of the  occurrence  of any other event which would have a
material  adverse  effect on the  aggregate  value of the  Collateral  or on the
security interests granted to the Agent in this Security Agreement.

change in law known to it which (i) adversely  affects or will adversely  affect
the validity,  perfection or priority of the security  interests granted hereby,

as the Agent may deem reasonably  necessary,  and the Debtor agrees to render to
the Agent, at the Debtor's cost and expense,  such clerical and other assistance
as  may  be  reasonably  requested  with  regard  thereto.  The  Agent  and  its
representatives  shall upon  reasonable  notice and during normal business hours
also  have the  right to enter  into  and  upon any  premises  where  any of the
Inventory or the  Equipment is located for the purpose of  inspecting  the same,
observing its use or protecting the interests of the Agent therein.

(b)  Audits.  The  Debtor  shall  permit  the  Lenders,   the  Agent  and  their
representatives  and advisors to review the operations of the Debtor and perform
the audits and  examinations  as  provided  in Section  6.1(l) of the  Revolving
Credit Agreement.

     maintain the Equipment in good operating condition,  ordinary wear and tear
     excepted.

     Section 10.19. Covenants Regarding Patent and Trademark Collateral.

(a)  Generally.  At  such  time as the  Debtor  shall  acquire  any  Patents  or
Trademarks,  it will comply with the terms,  covenants  and  warranties  of this
Section 4.19.

(b) Continued Use of Trademark.  The Debtor (either itself or through licensees)
will, unless the Debtor shall reasonably determine,  after consultation with the
Agent,  that a Trademark  is of  negligible  economic  value to the Debtor,  (i)
continue  to use each  Trademark  on each  and  every  Trademark  class of goods
applicable  to its current  products  and  services as  reflected in its current
catalogs,  brochures and price lists in order to maintain each Trademark in full
force and free from any claim of  abandonment  for non-use,  (ii) maintain as in
the past the quality of products  and  services  offered  under each  Trademark,
(iii) employ each Trademark with the appropriate  notice of  registration,  (iv)
not adopt or use any mark which is confusingly  similar to a colorable imitation
of any Trademark and (v) not (and not permit any licensee or sublicensee thereof
to) do any act or knowingly  omit to do any act whereby any Trademark may become
invalidated.

(c) No  Abandonment.  The Debtor will not,  unless the Debtor  shall  reasonably
determine,  after  consultation  with the Agent,  that a Patent is of negligible
economic  value to the  Debtor,  do any act,  or  knowingly  omit to do any act,
whereby any Patent may be abandoned or dedicated.

(d) Notice of Abandonment or Adverse Determinations. The Debtor shall notify the
Agent  immediately if it knows,  or has reason to know,  that any application or
registration  relating  to any  Patent or  Trademark  may  become  abandoned  or
dedicated,  or of any adverse determination or development  (including,  without
limitation,  the institution of, or any such determination or development in any
proceeding  in the United  States  Patent and  Trademark  Office or any court of
tribunal in any  country)  regarding  the  Debtor's  ownership  of any Patent or
Trademark, its right to register the same or keep and maintain the same.

(e) Filings After Notice to Agent.  In no event shall the Debtor,  either itself
or through any agent,  employee,  licensee or designee,  file an application for
registration  of any  Patent or  Trademark  with the  United  States  Patent and
Trademark  Office or any  similar  office or agency in any other  country or any
political  subdivision  thereof,  unless it promptly informs the Agent and, upon
request of the Agent, executes and delivers any and all agreements, instruments,
documents  and papers as the Agent may request to evidence the Agent's  security
interest in such Patent or Trademark and the goodwill and general intangibles of
the  Debtor  relating  thereto or  represented  thereby,  and the Debtor  hereby
constitutes the Agent its attorney-in-fact to execute and file all such writings
for the foregoing purposes, all such acts of such attorney being hereby ratified
and confirmed.

(f) Pursuit of Applications  and Maintenance of  Registrations.  The Debtor will
take all necessary  steps,  including,  without  limitation,  in any  proceeding
before the United States Patent and  Trademark  Office or any similar  office or
agency in any other country or any political  subdivision  thereof,  to maintain
and pursue each  application  (and to obtain the relevant  registration)  and to
maintain each  registration  of the Patents and  Trademarks,  including  without
limitation, filing of applications for renewal, affidavits of use and affidavits
of incontestability;  provided,  however, that no such Patent or Trademark shall
be required to be  maintained  or pursued to the extent such Patent or Trademark
is  determined  by the  Debtor,  after  consultation  with the  Agent,  to be of
negligible economic value to the Debtor.

(g) Notice of  Infringement.  If any of the Patent and  Trademark  Collateral is
infringed,  misappropriated  or  diluted  by a third  party,  the  Debtor  shall
promptly  notify the Agent after it learns thereof and shall,  unless the Debtor
shall reasonably determine,  after consultation with the Agent, that such Patent
and Trademark Collateral is of negligible economic value to the Debtor, promptly
sue for infringement, misappropriation of dilution, seek injunctive relief where
appropriate   and  recover   any  and  all   damages   for  such   infringement,
misappropriation  or  dilution,  or take such other  action as the Debtor  shall
reasonably deem appropriate  under the  circumstances to protect such Patent and
Trademark Collateral.

Section 10.20.  Termination of Federal  Contracts.  With respect to each Federal
Contract in respect of which the Debtor is required to execute an  Assignment of
Federal  Contract in accordance with Section 4.21 hereof,  the Debtor shall give
prompt written  notice to the Agent if the U.S.  Government  shall  terminate or
threaten to  terminate  (whether  for  convenience  or default) any such Federal
Contract  with the Debtor  having a value  (including  unexercised  options)  of
$100,000 or more. In addition,  the Debtor shall give prompt  written  notice to
the Agent if the U.S.  Government  shall  terminate or threaten to terminate any
contract between the U.S.  Government and any other prime contractor under which
the  Debtor  is a  subcontractor  if the  value of such  subcontract  (including
unexercised options) is $100,000 or more.

Section 10.21. Federal Contracts. The Debtor shall provide to the Agent, as soon
as reasonably  practicable but not later than forty-five (45) days following the
end of each Fiscal Quarter,  a report identifying each Federal Contract to which
it is a party,  having  attached  thereto  a copy of the first two pages of such
Federal  Contract  and any  amendment  thereto,  to the  extent  not  previously
provided to the Agent.  At the request of the Agent  (unless an Event of Default
shall have  occurred and be  continuing,  in which case no such request shall be
required),  the Debtor shall  execute and deliver to the Agent an  Assignment of
Federal Contract, in substantially the form of Exhibit A hereto (the "Assignment
of Federal Contract"), and execute any other instruments or take any other steps
required  by the Agent in order  that all moneys due or to become due under such
Federal  Contracts shall be assigned to the Agent and notice thereof given under
the Assignment of Claims Act, including without  limitation  delivery of Notices
of Assignments with respect to each Federal Contract as contemplated by Appendix
A to Exhibit A hereto.

Section 10.22.  Reimbursement Obligation.  Should the Debtor fail to comply with
the provisions of this Security Agreement, the Revolving Credit Agreement or any
other agreement relating to the Collateral such that the value of any Collateral
or the validity,  perfection,  rank or value of any security interest granted to
the  Agent  hereunder  or  thereunder  is  thereby   diminished  or  potentially
diminished or put at risk (as reasonably  determined by the Agent), the Agent on
behalf of the Debtor may, but shall not be required to,  effect such  compliance
on behalf of the Debtor,  and the Debtor shall  reimburse the Agent for the cost
thereof on demand,  and interest shall accrue on such  reimbursement  obligation
from the date the relevant  costs are incurred  until  reimbursement  thereof in
full at the Default Rate.

ARTICLE XI.

                                      REMEDIES; RIGHTS UPON DEFAULT

Section 11.01. UCC Rights.  In the event that any portion of the Obligations has
been declared or becomes due and payable in accordance with the Revolving Credit
Agreement or other Credit  Documents and such  Obligations have not been paid in
full,  the Agent may in addition to all other rights and remedies  granted to it
in this Security  Agreement and in any other  instrument or agreement  securing,
guarantying,  evidencing or relating to the Obligations, exercise (i) all rights
and  remedies of a secured  party under the UCC (whether or not in effect in the
jurisdiction  where  such  rights  are  exercised)  and  (ii) all  other  rights
available to the Agent at law or in equity.

Section 11.02. Payments on Collateral.  Without limiting the rights of the Agent
under any other  provision of this  Security  Agreement,  if an Event of Default
shall occur and be continuing:

(i) all payments  received by the Debtor under or in connection  with any of the
Collateral  shall  be held by the  Debtor  in  trust  for the  Agent,  shall  be
segregated  from other funds of the Debtor and shall  forthwith  upon receipt by
the Debtor be turned  over to the  Agent,  in the same form as  received  by the
Debtor  (duly  indorsed  by the  Debtor  to the  Agent,  if  required  to permit
collection thereof by the Agent); and

(ii) all such  payments  received  by the  Agent  (whether  from the  Debtor  or
otherwise)  may, in the sole  discretion  of the Agent,  be held by the Agent as
collateral  security for, and/or then or at any time thereafter applied in whole
or in part by the Agent to the payment of, the expenses and the  Obligations  as
set forth in Section 5.11 hereof.

Section 11.03.  Possession of Collateral.  In furtherance of the foregoing,  the
Debtor  expressly  agrees  that,  if an  Event of  Default  shall  occur  and be
continuing, the Agent may (i) by judicial powers, or without judicial process if
it can be done without breach of the peace, enter any premises where any of such
Collateral is or may be located and,  without  charge or liability to the Agent,
seize and remove such  Collateral from such premises and (ii) have access to and
use of the Debtor's books and records relating to such Collateral.

Section 11.04.    Sale of Collateral; Notice.

(a) Sale of Collateral.  The Debtor expressly agrees that if an Event of Default
shall occur and be continuing, the Agent, without demand of performance or other
demand or notice of any kind (except the notice  specified below of the time and
place of any public or private  sale) to or upon the Debtor or any other  Person
(all of which  demands  and/or  notices are hereby  waived by the  Debtor),  may
forthwith (i) apply the cash, if any, then held by it as collateral as specified
in Section  5.11 hereof and (ii) if there shall be no cash or such cash shall be
insufficient to pay the Obligations in full, collect,  receive,  appropriate and
realize upon the Collateral,  and/or sell, assign,  give an option or options to
purchase or otherwise  dispose of and deliver the  Collateral (or contract to do
so) or any part thereof in one or more parcels (which need not be in round lots)
at public or  private  sale,  at any  office of the Agent or  elsewhere  in such
manner as is  commercially  reasonable and, as the Agent may deem best, for cash
or on credit or for future delivery  without  assumption of any credit risk. The
Agent shall have the right upon any such public sale,  and, if the Collateral is
of a type customarily  sold in a recognized  market or is of a type which is the
subject of widely distributed  standard price quotations,  upon any such private
sale or sales,  to purchase the whole or any part of the Collateral so sold, and
thereafter to hold the same,  absolutely and free from any right or claim of any
kind. To the extent  permitted by applicable  law, the Debtor waives all claims,
damages  and  demands  against  the  Agent  arising  out  of  the   foreclosure,
repossession, retention or sale of the Collateral.

(b) Notice of Sale. Unless the Collateral threatens to decline speedily in value
or is of a type  customarily sold on a recognized  market,  the Agent shall give
the Debtor  ten (10)  days'  written  notice of its  intention  to make any such
public or private sale or sale at a broker's board or on a securities  exchange.
Such  notice  shall (i) in the case of a public  sale,  state the time and place
fixed  for  such  sale,  (ii) in the  case of sale at a  broker's  board or on a
securities  exchange,  state the board or  exchange  at which such sale is to be
made and the day on which the  Collateral,  or the portion  thereof  being sold,
will first be offered  for sale and (iii) in the case of a private  sale,  state
the day after which such sale may be consummated.  The Agent shall not obligated
to make any such sale  pursuant  to any such  notice.  The Agent may adjourn any
public or private  sale or cause the same to be  adjourned  from time to time by
announcement at the time and place fixed for the sale, and such sale may be made
at any time or place to which the same may be so  adjourned.  In the case of any
sale of all or any part of the Collateral on credit or for future delivery,  the
Collateral  so sold may be retained by the Agent until the selling price is paid
by the purchaser thereof, but the Agent shall not incur any liability in case of
the failure of such purchase to take up and pay for the  Collateral so sold and,
in the case of such failure, such Collateral may again be sold upon like notice.

(c) Special  Provisions  Relating to Sales of Securities.  The Debtor recognizes
that  the  Agent  may be  unable  to  effect  a  public  sale  of any or all the
Collateral  constituting a "security" (as such term is defined in the Securities
Act) by reason of  certain  prohibitions  contained  in the  Securities  Act and
applicable state securities laws or otherwise, and may be compelled to resort to
one or more private sales thereof to a restricted  group of purchasers that will
be obliged to agree,  among other things,  to acquire such  securities for their
own account for  investment  and not with a view to the  distribution  or resale
thereof.  The Debtor  acknowledges  and agrees  that any such  private  sale may
result in prices and other terms less  favorable than if such sale were a public
sale and, notwithstanding such circumstances,  agrees that any such private sale
shall be deemed to have been made in a commercially reasonable manner. The Agent
shall be under no obligation to delay a sale of any of Collateral constituting a
security  for the  period of time  necessary  to permit  the  issuer  thereof to
register  such  securities  for public sale under the  Securities  Act, or under
applicable state securities laws, even if such issuer would agree to do so.

Section 11.05.  Rights of Purchasers.  Upon any sale of the Collateral  (whether
public or  private),  the Agent  shall  have the right to  deliver,  assign  and
transfer  to the  purchaser  thereof  the  Collateral  so sold.  Each  purchaser
(including  the  Agent)  at any such  sale  shall  hold the  Collateral  so sold
absolutely,  free from any claim or right of whatever kind, including any equity
or right of redemption of the Debtor who, to the extent permitted by law, hereby
specifically waives all rights of redemption, including, without limitation, any
right to redeem the Collateral  under Section 9-506 of the UCC, and any right to
a judicial or other stay or approval  which it has or may have under any law now
existing or hereafter adopted.

Section 11.06.    Additional Rights of the Agent.

(a) Right to Maintain Proceedings.  The Agent (i) shall have the right and power
to institute and maintain such suits and proceedings as it may deem  appropriate
to protect and enforce the rights  vested in it by this  Security  Agreement and
(ii) may proceed by suit or suits at law or in equity to enforce such rights and
to foreclose  upon the  Collateral and to sell all or, from time to time, any of
the   Collateral   under  the  judgment  or  decree  of  a  court  of  competent
jurisdiction.

(b)  Appointment  of  Receiver.  The Agent  shall,  to the extent  permitted  by
applicable law,  without notice to the Debtor to any party claiming  through the
Debtor,  without regard to the solvency or insolvency at such time of any Person
then liable for the  payment of any of the  Obligations,  without  regard to the
then value of the Collateral and without requiring any bond from any complainant
in such  proceedings,  be entitled as a matter of right to the  appointment of a
receiver  or  receivers  (who may be the  Agent) of the  Collateral  or any part
thereof,  pending  such  proceedings,  with such powers as the court making such
appointment  shall  confer,  and to the  entry  of an order  directing  that the
profits, revenues and other income of the property constituting the whole or any
part of the Collateral be segregated,  sequestered and impounded for the benefit
of the Agent,  and the Debtor  irrevocably  consents to the  appointment of such
receiver or receivers and to the entry of such order.

(c) No Duty to  Exercise  Rights.  In no event  shall the Agent have any duty to
exercise any rights or take any steps to preserve the rights of the Agent in the
Collateral,  nor shall the Agent be liable to the Debtor or any other Person for
any loss caused by the Agent's failure to meet any obligation imposed by Section
9-207 of the UCC or any successor provision. Without limiting the foregoing, the
Agent  shall be deemed to have  exercised  reasonable  care in the  custody  and
preservation  of the  Collateral in its possession if the Collateral is accorded
treatment  substantially equal to that which the Agent accords its own property,
it being understood that the Agent shall not have any duty or responsibility for
(i) ascertaining or taking action with respect to calls, conversions, exchanges,
maturities,  tenders or other matters relative to any Collateral, whether or not
the Agent has or is deemed to have knowledge of such matters, or (ii) taking any
necessary  steps to preserve  rights  against any  parties  with  respect to any
Collateral.

Section 11.07.    Remedies Not Exclusive, etc.

(a) Remedies Not Exclusive. No remedy conferred upon or reserved to the Agent in
this  Security  Agreement  is intended to be  exclusive  of any other  remedy or
remedies,  but every such remedy shall be cumulative and shall be in addition to
every other  remedy  conferred  herein or now or  hereafter  existing at law, in
equity or by statute.

(b)  Restoration  of Rights.  If the Agent shall have  proceeded  to enforce any
right,  remedy or power under this Security Agreement and the proceeding for the
enforcement  thereof shall have been discontinued or abandoned for any reason or
shall have been  determined  adversely  to the  Agent,  the Debtor and the Agent
shall,   subject  to  any  determination  in  such  proceeding,   severally  and
respectively  be  restored  to their  former  positions  and  rights  under this
Security Agreement,  and thereafter all rights, remedies and powers of the Agent
shall continue as though no such proceedings had been taken.

(c)  Enforcement.  All rights of action  under this  Security  Agreement  may be
enforced by the Agent without the  possession of any  instrument  evidencing any
Obligation or the production  thereof at any trial or other proceeding  relative
thereto, and any suit or proceeding  instituted by the Agent shall be brought in
its name and any judgment shall be held as part of the Collateral.

Section 11.08.    Waiver and Estoppel.

(a) No Actions to Impede Sale of Collateral. The Debtor agrees, to the extent it
may lawfully do so, that it will not at any time in any manner  whatsoever claim
or take the benefit or advantage of any appraisal,  valuation,  stay, extension,
moratorium,  turnover or redemption  law, or any law permitting it to direct the
order in which the  Collateral  shall be sold,  now or at any time  hereafter in
force  which  may  delay,   prevent  or  otherwise  affect  the  performance  or
enforcement  of this  Security  Agreement,  and  hereby  waives  all  benefit or
advantage of all such laws. The Debtor covenants that it will not hinder,  delay
or impede  the  execution  of any power  granted  to the Agent in this  Security
Agreement, any Assignment of Federal Contract or any other Credit Document.

(b) Collateral Sold As An Entirety. The Debtor, to the extent it may lawfully do
so, on behalf of itself and all who claim through or under it, including without
limitation any and all  subsequent  creditors,  vendees,  assignees and lienors,
waives  and  releases  all  rights to demand or to have any  marshalling  of the
Collateral upon any sale, whether made under any power of sale granted herein or
pursuant to judicial  proceedings or under any foreclosure or any enforcement of
this Security Agreement,  and consents and agrees that all of the Collateral may
at any such sale be offered and sold as an entirety.

(c) Waiver of  Notices.  The Debtor  waives,  to the  extent  permitted  by law,
presentment,  demand,  protest  and any notice of any kind  (except  the notices
expressly required hereunder) in connection with this Security Agreement and any
action taken by the Agent with respect to the Collateral.

Section 11.09.    Power of Attorney; Powers Coupled With An Interest.

(a) Power of Attorney.  Without limiting any other right granted hereunder,  the
Debtor hereby irrevocably constitutes and appoints the Agent, with full power of
substitution,  as its true and  lawful  attorney-in-fact  with full  irrevocable
power and  authority in the place and stead of the Debtor and in the name of the
Debtor  or in its  own  name,  from  time  to  time  in the  Agent's  reasonable
discretion,  for the  purpose  of  carrying  out  the  terms  of  this  Security
Agreement,  to take any and all  appropriate  action and to execute  any and all
documents and instruments  which may be necessary or desirable to accomplish the
purpose of this Security  Agreement and,  without limiting the generality of the
foregoing,  hereby gives the Agent the power and right, on behalf of the Debtor,
without notice to or assent by the Debtor, to do the following:

     (i)  to  pay  or  discharge  taxes,  liens,  security  interests  or  other
     encumbrances levied or placed on or threatened against the Collateral;

(ii) to effect  any  repairs  or any  insurance  called for by the terms of this
Security  Agreement or any other Credit Document,  and to pay all or any part of
the premiums therefor and the costs thereof;

(iii) upon the occurrence and  continuance of any Event of Default and otherwise
to the  extent  provided  in this  Security  Agreement,  (A) to direct any party
liable for any payment  under any of the  Collateral  to make payment of any and
all moneys due and to come due thereunder  directly to the Agent or as the Agent
shall direct,  (B) to receive  payment of and receipt for, and to demand and sue
for, any and all moneys,  claims and other  amounts due and to become due at any
time in respect of or arising out of the Collateral, (C) to sign and indorse and
receive,  take, assign and deliver, any checks,  notes,  drafts,  negotiable and
non-negotiable  instruments,  any invoices,  freight or express bills,  bills of
lading,  storage or warehouse  receipts,  drafts against  debtors,  assignments,
verifications  and  notices in  connection  with  accounts  and other  documents
relating to the  Collateral,  (D) to  commence,  settle,  compromise,  compound,
prosecute,  defend or adjust any claim,  suit, action or proceeding with respect
to, or in connection  with, the  Collateral,  (E) to sell,  transfer,  assign or
otherwise  deal in or with the  Collateral  or any part  thereof,  as fully  and
effectively  as if the Agent were the absolute  owner  thereof and (F) to do, at
its option,  but at the expense of the Debtor, at any time or from time to time,
all acts and things  which the Agent deems  necessary  to  protect,  preserve or
realize upon the Collateral and the Agent's security interest therein,  in order
to effect the intent of this Security Agreement, all as fully and effectively as
the Debtor might do.

(b) Powers Coupled With an Interest.  All authorizations and agencies granted or
provided  herein with respect to the  Collateral,  including the powers  granted
under clause (a) of this Section 5.9, are irrevocable and powers coupled with an
interest.

Section 11.10. Certain Provisions Relating to Securities. Solely with respect to
any Collateral  constituting a "security" (as defined in the Securities Act), if
an Event of Default shall have occurred and be continuing,  all such  securities
(as defined in the Securities Act)  constituting a part of the Collateral shall,
at the  request  of the  Agent,  be  registered  in the name of the Agent or its
nominee,  and the Agent or its nominee may  thereafter  exercise (i) all voting,
corporate and other rights,  powers and privileges pertaining to such Collateral
at any meeting of shareholders of the issuer thereof or otherwise,  and (ii) any
and all  rights of  conversion,  exchange,  subscription  and any other  rights,
privileges or options  pertaining to such  Collateral as if it were the absolute
owner  thereof  (including,  without  limitation,  the right to  exchange at its
discretion  any  and  all  such  Collateral  upon  the  merger,   consolidation,
reorganization, recapitalization or other fundamental change in the structure of
any such  issuer,  or upon the exercise by the Debtor or the Agent of any right,
privilege or option pertaining to such Collateral,  and in connection therewith,
the right to deposit and deliver any and all such Collateral with any committee,
depositary, transfer agent, registrar or other designated agency upon such terms
and conditions as it may determine), all without liability except to account for
property  actually  received  by it and except as  provided  in  Section  5.6(c)
hereof,  but the Agent  shall  have no duty to the Debtor to  exercise  any such
right, privilege or option and shall not be responsible for any failure to do so
or delay in so doing.

     Section 11.11. Application of Monies. The proceeds of any sale of, or other
     realization upon, all or any part of the Collateral shall be applied by the
     Agent in the following order of priority:

                  first,  to  payment  of the  expenses  of such  sale or  other
realization,  including reasonable  compensation to the Agent and its agents and
counsel,  and all  expenses,  liabilities  and advances  incurred or made by the
Agent, its agents and counsel in connection  therewith or in connection with the
care, safekeeping or otherwise of any or all of the Collateral;

     second,  to  payment  of the  Obligations,  in such  order as the Agent may
     elect; and

                  third, any surplus then remaining shall be paid to the Debtor,
or its  successors  or assigns,  or to  whomsoever  may be lawfully  entitled to
receive the same (including  pursuant to Section 9-504(1)(C) of the UCC) or as a
court of competent jurisdiction may direct.

ARTICLE XII.

                                              MISCELLANEOUS

Section 12.01.  Notices.  All notices,  requests and other  communications  to a
party  hereunder  shall be in  writing  and shall be given to such  party at its
address set forth on the  signature  page  hereof or such other  address as such
party may hereafter  specify for that purpose by notice to the other.  Each such
notice,  request or other  communication  shall be effective  (i) in the case of
telephonic notice (to the extent expressly permitted hereunder), when made, (ii)
in the case of notice delivered by overnight  express courier,  one Business Day
after the Business Day such notice was delivered to such  courier,  (iii) in the
case of notice  delivered by first class mail,  three  Business Days after being
deposited in the mail, postage prepaid,  return receipt  requested,  (iv) in the
case of  notice  by hand,  when  delivered,  or (v) in the case of notice by any
customary means of telecommunication, when sent provided confirmation of receipt
or answer back has been received,  in each case if addressed to any party hereto
as provided herein.  Rejection or refusal to accept, or the inability to deliver
because of a changed address of which no notice was given,  shall not affect the
validity of notice given in accordance with this section.

Section 12.02. No Waiver;  Cumulative  Remedies.  The Agent shall not by any act
(except by a written  instrument  pursuant  to Section  6.3 hereof) be deemed to
have waived any right or remedy hereunder. No failure to exercise, nor any delay
in exercising,  on the part of the Agent any right, power or privilege hereunder
shall operate as a waiver thereof.  No single or partial  exercise of any right,
power or  privilege  hereunder  shall  preclude  any other or  further  exercise
thereof or the exercise of any other right, power or privilege.  A waiver by the
Agent  of any  right  or  remedy  hereunder  on any one  occasion  shall  not be
construed as a bar to any right or remedy which the Agent would  otherwise  have
on any future occasion.  The rights and remedies herein provided are cumulative,
may be  exercised  singly or  concurrently  and are not  exclusive  of any other
rights or remedies provided by law.

Section 12.03.  Amendments and Waivers.  None of the terms or provisions of this
Security Agreement may be amended,  supplemented or otherwise modified except by
a written  instrument  executed by the Debtor and the Agent;  provided  that any
provision of this  Security  Agreement may be waived by the Agent in a letter or
agreement  executed by the Agent or by telex or facsimile  transmission from the
Agent.

Section 12.04. Successors and Assigns. The provisions of this Security Agreement
shall be binding  upon and inure to the benefit of the parties  hereto and their
respective  successors and assigns;  provided,  however, that the Debtor may not
assign or transfer any of its rights or obligations  hereunder without the prior
written consent of the Agent.

Section 12.05.  Governing Law. THIS SECURITY  AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE  WITH THE LAWS OF THE  COMMONWEALTH  OF VIRGINIA,  OTHER
THAN ITS LAWS RESPECTING CHOICE OF LAW OTHER THAN THOSE CONTAINED IN THE UCC.

Section 12.06.    Limitation by Law; Severability.

(a) All rights,  remedies and powers provided in this Security  Agreement may be
exercised  only to the extent  that the  exercise  thereof  does not violate any
applicable  provision of law, and all the provisions of this Security  Agreement
are intended to be subject to all applicable  mandatory  provisions of law which
may be controlling  and to be limited to the extent  necessary so that they will
not render this Security Agreement  invalid,  unenforceable in whole or in part,
or not entitled to be recorded,  registered or filed upon the  provisions of any
applicable law.

(b) If any provision hereof is invalid and  unenforceable  in any  jurisdiction,
then, to the fullest extent  permitted by law, (i) the other  provisions  hereof
shall  remain  in full  force  and  effect  in such  jurisdiction  and  shall be
liberally  construed in favor of the Agent in order to carry out the  intentions
of the parties  hereto as nearly as may be possible and (ii) the  invalidity  or
unenforceability  of any provision hereof in any  jurisdiction  shall not affect
the validity or enforceability of such provision in any other jurisdiction.

Section  12.07.  Counterparts.  This  Security  Agreement may be executed in any
number of counterparts and by different parties hereto on separate counterparts,
each complete set of which, when so executed and delivered by all parties, shall
be an original,  but all such counterparts shall together constitute but one and
the same instrument.

Section  12.08.  Expenses of the Agent.  The Debtor  shall pay to the Agent from
time to time upon demand, all of the costs and expenses incurred by the Agent or
any Lender (including, without limitation, the reasonable fees and disbursements
of counsel  and any  amounts  payable by the Agent or any Lender to any of their
respective   agents)  (i)  arising  in  connection   with  the   administration,
modification, amendment, waiver or termination of this Security Agreement or any
document or agreement  contemplated hereby or any consent or waiver hereunder or
thereunder  or (ii)  incurred  in  connection  with the  administration  of this
Security  Agreement,  or any document or agreement  contemplated  hereby,  or in
connection  with the  administration,  sale or other  disposition  of Collateral
hereunder  or  under  any  document  or  agreement  contemplated  hereby  or the
preservation,  protection or defense of the rights of the Agent or any Lender in
and to the Collateral.

Section  12.09.  Indemnification.  The  Debtor  shall  at  all  times  hereafter
indemnify, hold harmless and, on demand, reimburse the Agent and the Lenders and
their  respective  subsidiaries,   affiliates,  successors,  assigns,  officers,
directors,   employees  and  agents,  and  their  respective  heirs,  executors,
administrators, successors and assigns (all of the foregoing parties, including,
but not limited to, the Agent, being hereinafter collectively referred to as the
"Indemnities" and individually as an "Indemnitee") from, against and for any and
all liabilities,  obligations,  claims, damages, actions,  penalties,  causes of
action, losses, judgments, suits, costs, expenses and disbursements,  including,
without  limitation,  attorney's  fees  (any  and  all  of the  foregoing  being
hereinafter  collectively referred to as the "Liabilities" and individually as a
"Liability")  which  the  Indemnitees,  or  any  of  them,  might  be or  become
subjected, by reason of, or arising out of the preparation, execution, delivery,
modification,  administration  or enforcement  of, or performance of the Agent's
rights  under,  this  Security  Agreement or any other  document,  instrument or
agreement  contemplated  hereby or executed in  connection  herewith;  provided,
however, that the Debtor shall not be liable to any Indemnitee for any Liability
caused solely by the gross negligence or willful  misconduct of such Indemnitee.
In no event shall any  Indemnitee,  as a condition to enforcing its rights under
this Section 6.9 or  otherwise,  be obligated to make a claim  against any other
Person (including,  without  limitation,  the Agent) to enforce its rights under
this Section 6.9.

Section 12.10.  Termination;  Survival.  This Security Agreement shall terminate
when the security interests granted hereunder have terminated and the Collateral
has been  released as  provided  in Section  2.6;  provided,  however,  that the
obligations  of the Debtor under Section 4.22 and the provisions of this Article
6 shall survive any such termination.

Section  12.11.  Judicial  Proceedings;  Waiver  of  Jury  Trial.  Any  judicial
proceeding  brought  against  the Debtor  with  respect to any Credit  Agreement
Related  Claim hereby may be brought in any court of competent  jurisdiction  in
the  Commonwealth  of Virginia,  County of Fairfax,  or any Federal court in the
Eastern  District of Virginia,  and, by execution  and delivery of this Security
Agreement,   the  Debtor  (a)  accepts,   generally  and  unconditionally,   the
nonexclusive  jurisdiction  of such courts and any related  appellate  court and
irrevocably  agrees to be bound by any judgment  rendered  thereby in connection
with any Credit Agreement Related Claim and (b) irrevocably waives any objection
it may now or hereafter have as to the venue of any such  proceeding  brought in
such a court or that such a court is an  inconvenient  forum.  The Debtor hereby
waives personal  service of process and consents that service of process upon it
may be made by certified or registered mail,  return receipt  requested,  at its
address specified or determined in accordance with the provisions of Section 6.1
hereof,  and service so made shall be deemed completed on the earlier of (x) the
receipt  thereof and (y) if sent by registered or certified mail (return receipt
requested),  the fifth (5th) Business Day after such service is deposited in the
mail. Nothing herein shall affect the right of the Agent to serve process in any
other  manner  permitted  by law or shall  limit the right of the Agent to bring
proceedings  against  the  Debtor in the courts of any other  jurisdiction.  Any
judicial proceeding by the Debtor against the Agent relating to or involving any
Credit  Agreement  Related Claim hereby shall be brought only in a court located
in the Commonwealth of Virginia,  County of Fairfax, or the Federal court in the
Eastern  District of Virginia.  THE DEBTOR AND THE AGENT HEREBY  UNCONDITIONALLY
WAIVE  TRIAL  BY JURY IN ANY  JUDICIAL  PROCEEDING  TO WHICH  THEY  ARE  PARTIES
INVOLVING ANY CREDIT AGREEMENT RELATED CLAIM.

Section  12.12.  Integration.  This  Security  Agreement  and the  other  Credit
Documents  constitute  the entire  agreement  of the  Agent,  the  Lenders,  the
Borrower and the other Credit  Parties with respect to the subject matter hereof
and  thereof,  and  there  are no  promises,  undertakings,  representations  or
warranties by the Agent or any Lender  relative to the subject  matter hereof or
thereof not  expressly  set forth or  referred to herein or in the other  Credit
Documents.

Section 12.13.  Authority of Agent. The Debtor  acknowledges that the rights and
responsibilities  of the Agent under this Security Agreement with respect to any
action  taken by the Agent or the exercise or  non-exercise  by the Agent of any
option,  voting right,  request,  judgment or other right or remedy provided for
herein or resulting or arising out of this Security  Agreement shall, as between
the Agent and the Lenders,  be governed by the Revolving Credit Agreement and by
such other  agreements with respect thereto as may exist from time to time among
them, but, as between the Agent and the Debtor,  the Agent shall be conclusively
presumed to be acting as agent for the Lenders with full and valid  authority so
to act or refrain from acting, and the Debtor shall not be under any obligation,
or entitlement, to make any inquiry respecting such authority.

Section 12.14. Headings,  Bold Type and Table of Contents. The section headings,

                                          ASSIGNMENT OF FEDERAL CONTRACT


                  This  ASSIGNMENT OF FEDERAL  CONTRACT,  dated as of _____,  __
(the  "Agreement"),  is made by  HAGLER  BAILLY  CONSULTING,  INC.,  a  Delaware

Agreement referred to below).

                                               W I T N E S S E T H:

                  WHEREAS,   the  Assignor  has  secured   certain   obligations
undertaken  by Hagler  Bailly,  Inc.  pursuant to the  provisions  of a Security
Agreement,  dated as of  ___________________,  ____ (as the same may be amended,
supplemented or otherwise modified from time to time, the "Security Agreement"),
by and between the Assignor and the Agent; and

                  WHEREAS,  the  Assignor  is a party to,  and from time to time
will  become  entitled  to  receive  moneys  under and by  virtue  of, a certain
contract  with,  involving or for the benefit of the United States of America or
any department,  agency or  instrumentality  thereof (herein  referred to as the

called the "Contract"); and

                  WHEREAS,  pursuant to the Security Agreement, the Assignor has
undertaken to effectuate the  assignment(s)  and other actions  contemplated  by
this Agreement.

                  NOW,  THEREFORE,  in  consideration  of the premises and other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the Assignor covenants and agrees as follows:

         1. Incorporation By Reference. The provisions of the Security Agreement
are  incorporated  herein by  reference,  and the terms  defined in the Security
Agreement are used herein with the same meanings.

         2.  Representations.  The Assignor represents and warrants to the Agent
that (a) the Contract is legal,  valid and binding on the  Assignor  and, to its
knowledge,  the other parties thereto,  is in full force and effect,  and is not
evidenced  by any  chattel  paper or  instrument,  (b) upon due  filing  of this
Agreement,  together  with a Notice of Assignment  substantially  in the form of
Appendix A hereto with the authorized representative, the execution and delivery
of this Agreement does not violate and is not in conflict with the provisions of
the  Contract,  (c) there has been no default on the part of the Assignor or any
other party to the Contract, (d) the Assignor has made no previous assignment of
the  Contract to any person and knows of no fact or defense that will render the
moneys due or to be due  thereunder  uncollectible,  (e) no financing  statement
covering  the  Contract  is on  file  in  any  public  office  except  financing
statements in favor of the Agent,  (f) no set-off or  counterclaim to any moneys
due or to become  due  under the  Contract  exists  on the date  hereof,  and no
agreement  has been made with any person  under which any  deduction or discount
may be claimed,  and (g) the address of the office where the Assignor  keeps its
records concerning the Contract is ____________________.

         3. Collateral. As security and collateral for the payment of all of the
Obligations  (defined in the Security  Agreement)  and for  performance  of, and
compliance  with,  by the  Assignor,  all of the terms,  covenants,  conditions,
stipulations,  and  agreements  contained in this  Agreement and in the Security
Agreement,  the Assignor hereby assigns to the Agent,  and grants to the Agent a
lien on and  security  interest  in,  all  moneys  and claims for moneys now and
hereafter  due and to  become  due to the  Assignor  under or by  reason  of the
Contract,  together  with all  cash and  non-cash  proceeds  thereof;  provided,
however,  that nothing  contained  herein shall impose upon the Agent any of the
obligations or liabilities of the Assignor under the Contract.

         4. Covenants. Until payment and performance in full of the Obligations,
the Assignor covenants as follows:

(c) The  Assignor  shall  place  on any and all  vouchers,  invoices,  or  other
instruments demanding payment under the Contract the direction that such payment
is to be made to the Agent in accordance with Section 5 of this Agreement.

(d) The Assignor shall promptly upon request execute,  acknowledge,  and deliver
any  notice,  financing  statement,   renewal,   affidavit,   deed,  assignment,
continuation statement,  security agreement,  certificate,  or other document as
the  Agent  may  require  in  order to  perfect,  preserve,  maintain,  protect,
continue, and/or extend the assignment, lien, and security interest of the Agent
under this  Agreement and its priority.  The Assignor  shall pay to the Agent on
demand all taxes,  costs, and expenses  incurred by the Agent in connection with
the  preparation,  execution,  recording,  and  filing of any such  document  or
instrument  mentioned  aforesaid,  and such taxes,  costs,  and  expenses  shall
constitute  and become a part of the  Obligations.  A carbon,  photographic,  or
other  reproduction  of  a  security  agreement  or  a  financing  statement  is
sufficient as a financing statement.

(e) The Assignor shall fully,  promptly,  and faithfully comply with and perform
its  obligations  and duties  under the  Contract in  accordance  with the terms
thereof and will make no changes or  amendments  to the Contract or terminate or
cancel the  Contract  without the prior  written  consent of the Agent except as
permitted by the Security  Agreement.  In the event that any change,  amendment,
termination  or  cancellation  of  the  Contract  is  made  or  effected  by the
Government,  the Assignor  will  promptly  notify the Agent thereof and promptly
furnish to the Agent a copy of any  document or  agreement  evidencing  any such
change, amendment, termination, or cancellation.

(f)      The Assignor will promptly

     (i) furnish to the Agent all information received by the Assignor affecting

to it with respect to the Collateral, except as otherwise provided in connection
with the Assignment of Federal Contract, if any as provided herein. However, the
Agent may, upon and during the continuance of an Event of Default or a Potential
Event of Default, notify Account Debtors obligated to make payments under any or
all Receivables or Other  Intangibles that the Agent has a security  interest in
such Collateral and that payments shall be made directly to the Agent.  Upon the
request of the Agent upon and during the continuance of an Event of Default or a
Potential  Event of Default,  as the case may be, the Debtor will so notify such
Account  Debtors  and  will  execute  such  contract  assignments,   notices  of
assignment or other  documents as may be required by such Account  Debtors.  The
Debtor will use all  reasonable  efforts to cause each Account  Debtor to comply
with the foregoing  instruction.  In furtherance  of the  foregoing,  the Debtor
authorizes the Agent upon and during the continuance of an Event of Default or a
Potential  Event of Default (i) to ask for,  demand,  collect,  receive and give
acquittances  and  receipts  for any and all amounts due and to become due under
any Collateral and in the name of the Debtor or its own name or otherwise,  (ii)
to  take  possession  of,  endorse  and  collect  any  checks,   drafts,  notes,
acceptances  or other  instruments  for the  payment  of  monies  due  under any
Collateral  and (iii) to file any claim or take any other action in any court of
law or equity or  otherwise  which it may deem  appropriate  for the  purpose of
collecting  any  amounts  due under any  Collateral.  The  Agent  shall  have no
obligation  to obtain or record any  information  relating to the source of such
funds or the obligations in respect of which payments have been made.

Section 2.04.     Segregation of Proceeds.

(a) Cash Collateral  Account  Maintained by Agent. Upon an Event of Default or a
Potential  Event of  Default,  the Agent shall have the right at any time during
the  continuance  thereof to cause to be opened and  maintained at the office of
the Agent in McLean,  Virginia a  non-interest  bearing  bank account (the "Cash
Collateral  Account") which will contain only Proceeds.  Any "cash proceeds" (as
such term is defined  in  Section  9-306(1)  of the UCC)  received  by the Agent
directly from Account  Debtors  obligated to make payments under  Receivables or
Other Intangibles  pursuant to Section 2.3 hereof or from the Debtor pursuant to
clause (b) of this Section 2.4,  whether  consisting of checks,  notes,  drafts,
bills of exchange, money orders,  commercial paper or other Proceeds received on
account of any  Collateral,  shall be promptly  deposited in the Cash Collateral
Account, and until so deposited shall be held in trust for the Agent as property
of the  Agent  and shall not be  commingled  with any  funds of the  Debtor  not
constituting  Proceeds  of  Collateral.  The name in which  the Cash  Collateral
Account is carried shall clearly  indicate that the funds deposited  therein are
the  property  of the  Debtor,  subject to the  security  interest  of the Agent
hereunder. Such Proceeds, when deposited,  shall continue to be security for the
Obligations   and  shall  not  constitute   payment  thereof  until  applied  as
hereinafter  provided.  The Agent shall have sole  dominion and control over the
funds deposited in the Cash Collateral Account,  and such funds may be withdrawn
therefrom only by the Agent.

(b) Deposit of  Proceeds  by the Debtor.  Upon notice by the Agent to the Debtor
that the Cash  Collateral  Account has been  opened,  the Debtor shall cause all
cash  Proceeds  collected  by it to be  delivered  to the Agent  forthwith  upon
receipt,  in the original  form in which  received  (with such  endorsements  or
assignments as may be necessary to permit collection  thereof by the Agent), and
for such  purpose the Debtor  hereby  irrevocably  authorizes  and  empowers the
Agent,  its officers,  employees and  authorized  agents to endorse and sign the
name of the Debtor on all checks, drafts, money orders or other media of payment
so delivered,  and such endorsements or assignments shall, for all purposes,  be
deemed to have been made by the Debtor prior to any  endorsement  or  assignment
thereof by the Agent.  The Agent may use any  convenient or customary  means for
the purpose of collecting  such checks,  drafts,  money orders or other media of
payment.

Section 2.05.  Verification  of  Receivables.  The Agent shall have the right to
make test  verifications of Receivables in any reasonable manner and through any
medium that it considers  advisable,  and the Debtor  agrees to furnish all such
assistance and  information  as the Agent may  reasonable  require in connection
therewith.  The Debtor at its expense will cause its chief financial  officer to
furnish to the Agent at any reasonable  time and from time to time promptly upon
the Agent's reasonable request,  the following reports:  (i) a reconciliation of
all Receivables, (ii) an aging of all Receivables, (iii) trial balances and (iv)
a test verification of such Receivables as the Agent may request.

Section 2.06.     Release of Collateral.

(a) Security  Interest of Agent Ceases Upon Permitted  Dispositions.  The Debtor
may sell or realize upon or transfer or otherwise  dispose of Collateral only to
the extent permitted by Section 4.13, and the security interests of the Agent in
such  Collateral so sold,  realized upon or disposed of (but not in the Proceeds
arising from such sale, realization or disposition) shall cease immediately upon
such sale, realization or disposition, without any further action on the part of
the Agent.  The Agent,  if requested in writing by the Debtor but at the expense
of the Debtor,  is hereby  authorized  and  instructed to deliver to the Account
Debtor or the purchaser or other transferee of any such Collateral a certificate
stating  that the Agent no longer  has a  security  interest  therein,  and such
Account Debtor or such purchaser or other  transferee  shall be entitled to rely
conclusively on such certificate for any and all purposes.

(b) Filing of  Termination  Statements.  Upon the  payment in full of all of the
Obligations  and if  there  is no  commitment  by any  Lender  to  make  further
advances,  incur obligations or otherwise give value, the Agent will (as soon as
reasonably  practicable  after receipt of notice from the Debtor  requesting the
same but at the  expense  of the  Debtor)  deliver  to the  Debtor  (i) for each
jurisdiction  in  which a UCC  financing  statement  is on file to  perfect  the
security  interests  granted to the Agent  hereunder,  a  termination  statement
(appropriately  completed)  to the  effect  that the  Agent no  longer  claims a
security interest under such financing statement,  and (ii) such other documents
as  the  Debtor  shall  reasonably  request   evidencing   satisfaction  of  the
Obligations  and the  release  of the  security  interests  granted to the Agent
hereunder.

ARTICLE III.

                                      REPRESENTATIONS AND WARRANTIES

         The Debtor represents and warrants that:

Section 3.01. Title to Collateral.  Except for the security interests granted to
the Agent  pursuant to this  Security  Agreement  and as otherwise  permitted by
Section 6.2(a) of the Revolving Credit  Agreement,  the Debtor is the sole owner
of each item of the Collateral,  having good and marketable title thereto,  free
and clear of any and all Liens.

Section 3.02.     Validity, Perfection and Priority of Security Interests.

(a) By complying  with Section 4.1 hereof,  the Debtor will have created a valid
security  interest in favor of the Agent in all existing  Collateral  and in all
identifiable  Proceeds of such  Collateral,  which security  interest (except in
respect of  Collateral  not located at a facility  identified  on  Schedule  3.7
hereto  and motor  vehicles  for  which the  exclusive  manner of  perfecting  a
security interest therein is by noting such security interest in the certificate
of title in accordance with local law) would be prior to the claims of a trustee
in bankruptcy under Section 544(a) of the Bankruptcy Code. Continuing compliance
by the Debtor  with the  provisions  of Section  4.2 hereof will also (i) create
valid security interests in all Collateral acquired after the date hereof and in
all  identifiable  Proceeds  of such  Collateral  and (ii) cause  such  security
interests in all Collateral and in all Proceeds which are (A) identifiable  cash
Proceeds of  Collateral  covered by  financing  statements  required to be filed
hereunder,  (B)  identifiable  Proceeds  in  which a  security  interest  may be
perfected  by such  filing  under  the UCC and  (C)  any  Proceeds  in the  Cash
Collateral Account to be duly perfected under the UCC, in each case prior to the
claims of a trustee in bankruptcy  under the Bankruptcy  Code (except in respect
of Collateral not located at a facility identified on Schedule 3.5 hereto).

(b) The  security  interests  of the  Agent  in the  Collateral  located  at the
facilities identified on Schedule 3.5 hereto rank first in priority.  Other than
financing   statements  or  other  similar  documents  perfecting  the  security
interests  in favor of the  Agent,  no  financing  statements,  deeds of  trust,
mortgages or similar documents covering all or any part of the Collateral are on
file or of record in any  government  office in any  jurisdiction  in which such
filing or recording  would be  effective to perfect a security  interest in such
Collateral,  nor is any of the Collateral in the possession of any Person (other
than the Debtor) asserting any claim thereto or security interest therein.

Section 3.03.  Enforceability of Receivables and Other Intangibles.  To the best
knowledge of the Debtor,  each  Receivable  and Other  Intangible is a valid and
binding obligation of the related Account Debtor in respect thereof, enforceable
in accordance with its terms,  except as such  enforceability  may be limited by
applicable bankruptcy,  insolvency,  reorganization,  moratorium or similar laws
affecting  the  enforcement  of  creditors'  rights  generally  and  by  general
provisions of equity (regardless of whether such enforceability is considered in
a  proceeding  in equity or at law),  and  complies  with any  applicable  legal
requirements.

Section 3.04.  Place of Business.  Schedule 3.4  correctly  sets forth the chief
executive  office and principal  place of business of the Debtor and the offices
of the Debtor where records  concerning  Receivables  and Other  Intangibles are
kept.

Section 3.05.  Location of  Collateral.  Schedule 3.5  correctly  sets forth the
location of all Equipment and Inventory,  other than rolling stock, aircraft and
goods in transit.  Except as otherwise  specified in Schedule 3.5, all Inventory
and Equipment  has been located at the address  specified on Schedule 3.5 at all
times during the  four-month  period prior to the date hereof while owned by the
Debtor.  All Inventory has been and will be produced in compliance with the Fair
Labor Standards Act, 29 U.S.C.  ss.ss.  201-219,  except for such non-compliance
which could not reasonably be expected to have a material  adverse effect on the
Debtor. No Inventory is evidenced by a negotiable  document of title,  warehouse
receipt  or bill of  lading.  No  non-negotiable  document  of title,  warehouse
receipt or bill of lading has been  issued to any person  other than the Debtor,
and the Debtor has retained possession of all of such non-negotiable  documents,
warehouse receipts and bills of lading. No amount payable under or in connection
with  any  of  the  Collateral  is  evidenced  by  promissory   notes  or  other
instruments.

Section 3.06.  Trade Names.  Schedule 3.6 correctly sets forth any and all trade
names,  division  names,  assumed  names or other  names  under which the Debtor
currently  transacts  business or has transacted  business within the four-month
period prior to the date hereof.

     Section 3.07. Patents and Trademarks. Schedule 3.7 correctly sets forth all
     Patents,  Patent licenses,  Trademarks and Trademark  licenses now owned by
     the Debtor.

ARTICLE IV.

                                                COVENANTS

                  The Debtor covenants and agrees that until all obligations and
liabilities in respect of the Obligations  shall have performed and paid in full
and  until  no  Standby   Letters  of  Credit  are  outstanding  or  fully  cash
collateralized and the Commitments are terminated:

Section 4.01. Perfection of Security Interests. The Debtor will, at its expense,
cause all filings and recordings and other actions  specified on Schedule 4.1 to
have been completed on or prior to the Effective Date.

Section 4.02.     Further Actions.

(a) At all times after the date hereof, the Debtor will, at its expense,  comply
with the following:

(i) as to all Receivables,  Other Intangibles,  Equipment and Inventory, it will
cause UCC financing statements and continuation statements to be filed and to be
on file in all  applicable  jurisdictions  as required  to perfect the  security
interests  granted to the Agent  hereunder,  to the extent that  applicable  law
permits perfection of a security interest by filing under the UCC;

(ii)  as to all  Proceeds,  it  will  cause  all UCC  financing  statements  and
continuation  statements  filed in accordance with clause (i) above to include a
statement or a checked box  indicating  that Proceeds of all items of Collateral
described herein are covered;

(iii) as to any amount payable under or in connection with any of the Collateral
which  shall  be or  shall  become  evidenced  by any  promissory  note or other
instrument,  the  Debtor  will  promptly  (but in no event  later  than ten (10)
Business Days after receipt of such note or instrument), pledge and deliver such
note or other  instrument to the Agent as part of the Collateral,  duly endorsed
in a manner reasonably satisfactory to the Agent;

(iv) at the request of the Agent,  the Debtor shall deliver all other Collateral
consisting  of  certificated  securities,  endorsed  for  transfer  in a  manner
reasonably  satisfactory  to the Agent (or  execute  a  securities  intermediary
account  control  agreement  to the  extent  possession  by the  Agent  of  such
securities is not feasible); and

(v) as to all Patents,  Patent licenses,  Trademarks or Trademark licenses,  the
Debtor will effect the recordation or renewal of the recordation of the security
interests of the Agent therein so as to maintain  valid and  perfected  security
interests  therein  under all  applicable  state and federal  laws.  (b) Further
Assurances.  The Debtor  will,  from time to time and at its  expense,  execute,
deliver,  file  or  record  such  UCC  financing  statements,  applications  for
certificates  of title  and such  other  statements,  assignments,  instruments,
documents,  agreements  or other  papers and take any other  action  that may be
necessary or desirable,  or that the Agent may reasonably  request,  in order to
create,  preserve,  perfect,  confirm or validate the  security  interest of the
Agent in the Collateral, to enable the Agent to obtain the full benefits of this
Security  Agreement  or to enable it to exercise  and enforce any of its rights,
powers and remedies hereunder,  including, without limitation, its right to take
possession of the Collateral.

(c) Signature. To the fullest extent permitted by law, the Debtor authorizes the
Agent to sign and file  financing and  continuation  statements  and  amendments
thereto with respect to the Collateral without its signature thereon.

Section 4.03. Change of Name, Identity or Structure.  The Debtor will not change
its name, identity or corporate structure in any manner and, except as set forth
on  Schedule  3.6,  will not conduct its  business  under any trade,  assumed or
fictitious  name unless it shall have given the Agent at least  forty-five  (45)
days'  prior  written  notice  thereof  and shall have taken all action (or made
arrangements to take such action  substantially  simultaneously with such change
if it is  impossible  to take such action in advance)  necessary  or  reasonably
requested  by the  Agent  to  amend  any  financing  statement  or  continuation
statement relating to the security interests granted hereby in order to preserve
such  security  interests  and to  effectuate  or maintain the priority  thereof
against all Persons.

Section 4.04.  Place of Business and Collateral.  The Debtor will not change the
location of (i) its places of business, (ii) its chief executive office or (iii)
the  office or other  locations  where it keeps or holds any  Collateral  or any
records relating thereto from the applicable  location listed on Schedule 3.4 or
3.5 unless,  prior to such change, it notifies the Agent forty-five (45) days in
advance of such change,  makes all UCC filings required by Section 4.2 and takes
all other action necessary or that the Agent may reasonably request to preserve,
perfect,  confirm and protect the security  interests granted hereby. The Debtor
will in no event  change the  location of any  Collateral  if such change  would
cause the security  interest granted hereby in such Collateral to lapse or cease
to be  perfected.  The Debtor  will at all times  maintain  its chief  executive
office within one of the forty-eight contiguous states in which Article 9 of the
uniform commercial code is in effect.

Section  4.05.  Fixtures.  The Debtor will not permit any  Equipment to become a
fixture  unless it shall  have  given the  Agent at least ten (10)  days'  prior
written  notice  thereof and shall have taken all such action and  delivered  or
caused to be delivered to the Agent all  instruments  and documents,  including,
without  limitation,  waivers and subordination  agreements by any landlords and
mortgagees, and filed all financing statements necessary or reasonably requested
by the Agent, to preserve and protect the security  interest  granted herein and
to effectuate or maintain the priority  thereof  against all Persons;  provided,
however,  that,  so long as no Event of  Default or  Potential  Event of Default
shall have  occurred  and be  continuing,  the Debtor  shall not be obligated to
comply with the provisions of this Section 4.5 with respect to the first $50,000
of Equipment (determined based on the then fair market value thereof).

Section 4.06.  Maintenance of Records.  The Debtor will keep and maintain at its
own cost and expense complete books and records relating to the Collateral which
are satisfactory to the Agent  including,  without  limitation,  a record of all
payments received and all credits granted with respect to the Collateral and all
of its other  dealings with the  Collateral.  The Debtor will mark its books and
records pertaining to the Collateral to evidence this Security Agreement and the
security interests granted hereby.  For the Agent' further security,  the Debtor
agrees  that the Agent  shall  have a special  property  interest  in all of the
Debtor's  books and records  pertaining to the  Collateral  and the Debtor shall
deliver  and  turn  over any  such  books  and  records  to the  Agent or to its
representatives at any time on demand of the Agent.

Section  4.07.  Compliance  with Laws The  Debtor  will  comply in all  material
respects with all acts, rules,  regulations,  orders,  decrees and directions of
any government or any state or local government  applicable to the Collateral or
any part  thereof or to the  operation of the  Debtor's  business  except to the
extent that the failure to comply  would not have a material  adverse  effect on
the  financial or other  condition of the Debtor;  provided,  however,  that the
Debtor may contest any act, rule, regulation,  order, decree or direction in any
reasonable  manner which shall not, in the sole opinion of the Agent,  adversely
affect the Agent's  rights or, in the case of  Collateral  located at a facility
identified on Schedule 3.7 hereto,  the first priority of its security  interest
in the Collateral.

Section 4.08. Payment of Taxes. The Debtor will pay promptly when due all taxes,
assessments and governmental charges or levies imposed upon the Collateral or in
respect of its income or  profits  therefrom,  as well as all claims of any kind
(including claims for labor, materials and supplies), except that no such charge
need be paid if (i) the  validity  thereof is being  contested  in good faith by
appropriate  proceedings and (ii) such charge is adequately  reserved against in
accordance  with  generally  accepted  accounting  principles,  as  consistently
applied.

Section 4.09.  Compliance with Terms of Accounts and Contracts.  The Debtor will
perform and comply in all material  respects with all of its  obligations  under
all agreements  relating to the Collateral to which it is a party or by which it
is bound.

Section  4.10.  Limitation on Liens on  Collateral.  The Debtor will not create,
permit or suffer to exist,  and will  defend  the  Collateral  and the  Debtor's
rights with respect  thereto  against and take such other action as is necessary
to  remove  any  Lien,  security  interest,  encumbrance,  or claim in or to the
Collateral other than the security interests created hereunder and such Liens to
the  extent  permitted  pursuant  to  Section  6.2(a)  of the  Revolving  Credit
Agreement.

Section 4.11. Limitations on Modifications of Receivables and Other Intangibles;
No Waivers or Extensions.  The Debtor will not (i) amend,  modify,  terminate or
waive any  provisions  of any material  Receivable  or Other  Intangible  in any
manner which might, when taken together with all such other Receivables or Other
Intangibles,  respectively,  materially  reduce the value of all  Receivables or
Other  Intangibles,  respectively,  in the  Collateral,  (ii)  fail to  exercise
promptly and  diligently  each and every  material right which it may have under
each  Receivable  and Other  Intangible  or (iii) fail to deliver to the Agent a
copy of each material demand,  notice or document received by it relating in any
way to any Receivable or Other Intangible.

Section  4.12.   Maintenance  of  Insurance.   The  Debtor  will  maintain  with
financially   sound  insurance   companies   licensed  to  do  business  in  the
jurisdictions  in which the  Collateral  is located  insurance  policies  on the
Inventory and Equipment in accordance  with the  provisions of Section 6.1(m) of
the Revolving Credit Agreement.

Section 4.13.  Limitations on  Dispositions  of Collateral.  The Debtor will not
directly or indirectly (through the sale of stock, merger or otherwise), without
the prior  written  consent of the Agent,  sell,  transfer,  lease or  otherwise
dispose of any of the Collateral,  or attempt, offer or contract to do so except
for (i) sales of Inventory in the ordinary course of its business for fair value
in  arm's-length  transactions  and  (ii) so long as no  Event  of  Default  (or
Potential  Event of Default) has occurred and is continuing,  dispositions  in a
commercially reasonable manner of Equipment which has become redundant, worn out
or obsolete or which should be replaced so as to improve  productivity,  so long
as the  proceeds  of any such  disposition  are (x) used to acquire  replacement
equipment  which has comparable or better utility and equivalent or better value
and which is subject to a first priority security interest in favor of the Agent
therein,  except  as  permitted  by  Section  6.2(a)  of  the  Revolving  Credit
Agreement, or (y) applied to repay the Obligations. The inclusion of Proceeds of
the Collateral under the security interests granted hereby shall not be deemed a
consent by the Agent to any sale or disposition of any Collateral  other than as
permitted by this Section 4.13.

Section 4.14. Further  Identification of Collateral.  The Debtor will furnish to
the Agent from time to time  statements and schedules  further  identifying  and
describing  the  Collateral  and  such  other  reports  in  connection  with the
Collateral as the Agent may reasonably request. The Debtor shall promptly notify
the Agent if the value of the Collateral located at the facilities identified on
Schedule 3.7 hereto is less than 80% of the value of all of the Collateral.

Section  4.15.  Notices.  The  Debtor  will  advise  the Agent  promptly  and in
reasonable detail (i) of any Lien, security interest,  encumbrance or claim made
or  asserted  against  any of the  Collateral,  other  than,  unless  reasonably
requested  by the Agent,  Liens  permitted  by Section  6.2(a) of the  Revolving
Credit  Agreement,  (ii)  of  any  material  change  in the  composition  of the
Collateral,  and (iii) of the  occurrence  of any other event which would have a
material  adverse  effect on the  aggregate  value of the  Collateral  or on the
security interests granted to the Agent in this Security Agreement.

Section 4.16.  Change of Law. The Debtor shall promptly  notify the Agent of any
change in law known to it which (i) adversely  affects or will adversely  affect
the validity,  perfection or priority of the security  interests granted hereby,
(ii)  requires  or will  require a change in the  proceedings  to be followed in
order to maintain and protect such  validity,  perfection  and priority or (iii)
could result in the Agent not having a perfected security interest in any of the
Collateral.

Section 4.17.     Right of Inspection.

(a) Access to Books and Records. The Debtor shall,  following any request by the
Agent and upon reasonable  notice,  permit the Agent or its  representatives  to
have  full  and free  access  during  normal  business  hours to all the  books,
correspondence and records of the Debtor,  and the Agent or its  representatives
may examine the same, take extracts therefrom, make photocopies thereof and have
such discussions with officers,  employees and public  accountants of the Debtor
as the Agent may deem reasonably  necessary,  and the Debtor agrees to render to
the Agent, at the Debtor's cost and expense,  such clerical and other assistance
as  may  be  reasonably  requested  with  regard  thereto.  The  Agent  and  its
representatives  shall upon  reasonable  notice and during normal business hours
also  have the  right to enter  into  and  upon any  premises  where  any of the
Inventory or the  Equipment is located for the purpose of  inspecting  the same,
observing its use or protecting the interests of the Agent therein.

(b)  Audits.  The  Debtor  shall  permit  the  Lenders,   the  Agent  and  their
representatives  and advisors to review the operations of the Debtor and perform
the audits and  examinations  as  provided  in Section  6.1(l) of the  Revolving
Credit Agreement.

     Section 4.18.  Maintenance  of Equipment.  The Debtor will, at its expense,
     maintain the Equipment in good operating condition,  ordinary wear and tear
     excepted.





Section 4.19.     Covenants Regarding Patent and Trademark Collateral.

(a)  Generally.  At  such  time as the  Debtor  shall  acquire  any  Patents  or
Trademarks,  it will comply with the terms,  covenants  and  warranties  of this
Section 4.19.

(b) Continued Use of Trademark.  The Debtor (either itself or through licensees)
will, unless the Debtor shall reasonably determine,  after consultation with the
Agent,  that a Trademark  is of  negligible  economic  value to the Debtor,  (i)
continue  to use each  Trademark  on each  and  every  Trademark  class of goods
applicable  to its current  products  and  services as  reflected in its current
catalogs,  brochures and price lists in order to maintain each Trademark in full
force and free from any claim of  abandonment  for non-use,  (ii) maintain as in
the past the quality of products  and  services  offered  under each  Trademark,
(iii) employ each Trademark with the appropriate  notice of  registration,  (iv)
not adopt or use any mark which is confusingly  similar to a colorable imitation
of any Trademark and (v) not (and not permit any licensee or sublicensee thereof
to) do any act or knowingly  omit to do any act whereby any Trademark may become
invalidated.

(c) No  Abandonment.  The Debtor will not,  unless the Debtor  shall  reasonably
determine,  after  consultation  with the Agent,  that a Patent is of negligible
economic  value to the  Debtor,  do any act,  or  knowingly  omit to do any act,
whereby any Patent may be abandoned or dedicated.

(d) Notice of Abandonment or Adverse Determinations. The Debtor shall notify the
Agent  immediately if it knows,  or has reason to know,  that any application or
registration  relating  to any  Patent or  Trademark  may  become  abandoned  or
dedicated,  or of any adverse determination or development  (including,  without
limitation,  the institution of, or any such determination or development in any
proceeding  in the United  States  Patent and  Trademark  Office or any court of
tribunal in any  country)  regarding  the  Debtor's  ownership  of any Patent or
Trademark, its right to register the same or keep and maintain the same.

(e) Filings After Notice to Agent.  In no event shall the Debtor,  either itself
or through any agent,  employee,  licensee or designee,  file an application for
registration  of any  Patent or  Trademark  with the  United  States  Patent and
Trademark  Office or any  similar  office or agency in any other  country or any
political  subdivision  thereof,  unless it promptly informs the Agent and, upon
request of the Agent, executes and delivers any and all agreements, instruments,
documents  and papers as the Agent may request to evidence the Agent's  security
interest in such Patent or Trademark and the goodwill and general intangibles of
the  Debtor  relating  thereto or  represented  thereby,  and the Debtor  hereby
constitutes the Agent its attorney-in-fact to execute and file all such writings
for the foregoing purposes, all such acts of such attorney being hereby ratified
and confirmed.

(f) Pursuit of Applications  and Maintenance of  Registrations.  The Debtor will
take all necessary  steps,  including,  without  limitation,  in any  proceeding
before the United States Patent and  Trademark  Office or any similar  office or
agency in any other country or any political  subdivision  thereof,  to maintain
and pursue each  application  (and to obtain the relevant  registration)  and to
maintain each  registration  of the Patents and  Trademarks,  including  without
limitation, filing of applications for renewal, affidavits of use and affidavits
of incontestability;  provided,  however, that no such Patent or Trademark shall
be required to be  maintained  or pursued to the extent such Patent or Trademark
is  determined  by the  Debtor,  after  consultation  with the  Agent,  to be of
negligible economic value to the Debtor.

(g) Notice of  Infringement.  If any of the Patent and  Trademark  Collateral is
infringed,  misappropriated  or  diluted  by a third  party,  the  Debtor  shall
promptly  notify the Agent after it learns thereof and shall,  unless the Debtor
shall reasonably determine,  after consultation with the Agent, that such Patent
and Trademark Collateral is of negligible economic value to the Debtor, promptly
sue for infringement, misappropriation of dilution, seek injunctive relief where
appropriate   and  recover   any  and  all   damages   for  such   infringement,
misappropriation  or  dilution,  or take such other  action as the Debtor  shall
reasonably deem appropriate  under the  circumstances to protect such Patent and
Trademark Collateral.

Section 4.20.  Termination  of Federal  Contracts.  With respect to each Federal
Contract in respect of which the Debtor is required to execute an  Assignment of
Federal  Contract in accordance with Section 4.21 hereof,  the Debtor shall give
prompt written  notice to the Agent if the U.S.  Government  shall  terminate or
threaten to  terminate  (whether  for  convenience  or default) any such Federal
Contract  with the Debtor  having a value  (including  unexercised  options)  of
$100,000 or more. In addition,  the Debtor shall give prompt  written  notice to
the Agent if the U.S.  Government  shall  terminate or threaten to terminate any
contract between the U.S.  Government and any other prime contractor under which
the  Debtor  is a  subcontractor  if the  value of such  subcontract  (including
unexercised options) is $100,000 or more.

Section 4.21. Federal Contracts.  The Debtor shall provide to the Agent, as soon
as reasonably  practicable but not later than forty-five (45) days following the
end of each Fiscal Quarter,  a report identifying each Federal Contract to which
it is a party,  having  attached  thereto  a copy of the first two pages of such
Federal  Contract  and any  amendment  thereto,  to the  extent  not  previously
provided to the Agent.  At the request of the Agent  (unless an Event of Default
shall have  occurred and be  continuing,  in which case no such request shall be
required),  the Debtor shall  execute and deliver to the Agent an  Assignment of
Federal Contract, in substantially the form of Exhibit A hereto (the "Assignment
of Federal Contract"), and execute any other instruments or take any other steps
required  by the Agent in order  that all moneys due or to become due under such
Federal  Contracts shall be assigned to the Agent and notice thereof given under
the Assignment of Claims Act, including without  limitation  delivery of Notices
of Assignments with respect to each Federal Contract as contemplated by Appendix
A to Exhibit A hereto.

Section 4.22.  Reimbursement  Obligation.  Should the Debtor fail to comply with
the provisions of this Security Agreement, the Revolving Credit Agreement or any
other agreement relating to the Collateral such that the value of any Collateral
or the validity,  perfection,  rank or value of any security interest granted to
the  Agent  hereunder  or  thereunder  is  thereby   diminished  or  potentially
diminished or put at risk (as reasonably  determined by the Agent), the Agent on
behalf of the Debtor may, but shall not be required to,  effect such  compliance
on behalf of the Debtor,  and the Debtor shall  reimburse the Agent for the cost
thereof on demand,  and interest shall accrue on such  reimbursement  obligation
from the date the relevant  costs are incurred  until  reimbursement  thereof in
full at the Default Rate.

ARTICLE V.

                                      REMEDIES; RIGHTS UPON DEFAULT

Section 5.01. UCC Rights.  In the event that any portion of the  Obligations has
been declared or becomes due and payable in accordance with the Revolving Credit
Agreement or other Credit  Documents and such  Obligations have not been paid in
full,  the Agent may in addition to all other rights and remedies  granted to it
in this Security  Agreement and in any other  instrument or agreement  securing,
guarantying,  evidencing or relating to the Obligations, exercise (i) all rights
and  remedies of a secured  party under the UCC (whether or not in effect in the
jurisdiction  where  such  rights  are  exercised)  and  (ii) all  other  rights
available to the Agent at law or in equity.

     Section 5.02.  Payments on Collateral.  Without  limiting the rights of the
     Agent under any other provision of this Security Agreement,  if an Event of
     Default shall occur and be continuing:

(i) all payments  received by the Debtor under or in connection  with any of the
Collateral  shall  be held by the  Debtor  in  trust  for the  Agent,  shall  be
segregated  from other funds of the Debtor and shall  forthwith  upon receipt by
the Debtor be turned  over to the  Agent,  in the same form as  received  by the
Debtor  (duly  indorsed  by the  Debtor  to the  Agent,  if  required  to permit
collection thereof by the Agent); and

(ii) all such  payments  received  by the  Agent  (whether  from the  Debtor  or
otherwise)  may, in the sole  discretion  of the Agent,  be held by the Agent as
collateral  security for, and/or then or at any time thereafter applied in whole
or in part by the Agent to the payment of, the expenses and the  Obligations  as
set forth in Section 5.11 hereof.

Section 5.03.  Possession of Collateral.  In  furtherance of the foregoing,  the
Debtor  expressly  agrees  that,  if an  Event of  Default  shall  occur  and be
continuing, the Agent may (i) by judicial powers, or without judicial process if
it can be done without breach of the peace, enter any premises where any of such
Collateral is or may be located and,  without  charge or liability to the Agent,
seize and remove such  Collateral from such premises and (ii) have access to and
use of the Debtor's books and records relating to such Collateral.

Section 5.04.     Sale of Collateral; Notice.

(a) Sale of Collateral.  The Debtor expressly agrees that if an Event of Default
shall occur and be continuing, the Agent, without demand of performance or other
demand or notice of any kind (except the notice  specified below of the time and
place of any public or private  sale) to or upon the Debtor or any other  Person
(all of which  demands  and/or  notices are hereby  waived by the  Debtor),  may
forthwith (i) apply the cash, if any, then held by it as collateral as specified
in Section  5.11 hereof and (ii) if there shall be no cash or such cash shall be
insufficient to pay the Obligations in full, collect,  receive,  appropriate and
realize upon the Collateral,  and/or sell, assign,  give an option or options to
purchase or otherwise  dispose of and deliver the  Collateral (or contract to do
so) or any part thereof in one or more parcels (which need not be in round lots)
at public or  private  sale,  at any  office of the Agent or  elsewhere  in such
manner as is  commercially  reasonable and, as the Agent may deem best, for cash
or on credit or for future delivery  without  assumption of any credit risk. The
Agent shall have the right upon any such public sale,  and, if the Collateral is
of a type customarily  sold in a recognized  market or is of a type which is the
subject of widely distributed  standard price quotations,  upon any such private
sale or sales,  to purchase the whole or any part of the Collateral so sold, and
thereafter to hold the same,  absolutely and free from any right or claim of any
kind. To the extent  permitted by applicable  law, the Debtor waives all claims,
damages  and  demands  against  the  Agent  arising  out  of  the   foreclosure,
repossession, retention or sale of the Collateral.

(b) Notice of Sale. Unless the Collateral threatens to decline speedily in value
or is of a type  customarily sold on a recognized  market,  the Agent shall give
the Debtor  ten (10)  days'  written  notice of its  intention  to make any such
public or private sale or sale at a broker's board or on a securities  exchange.
Such  notice  shall (i) in the case of a public  sale,  state the time and place
fixed  for  such  sale,  (ii) in the  case of sale at a  broker's  board or on a
securities  exchange,  state the board or  exchange  at which such sale is to be
made and the day on which the  Collateral,  or the portion  thereof  being sold,
will first be offered  for sale and (iii) in the case of a private  sale,  state
the day after which such sale may be consummated.  The Agent shall not obligated
to make any such sale  pursuant  to any such  notice.  The Agent may adjourn any
public or private  sale or cause the same to be  adjourned  from time to time by
announcement at the time and place fixed for the sale, and such sale may be made
at any time or place to which the same may be so  adjourned.  In the case of any
sale of all or any part of the Collateral on credit or for future delivery,  the
Collateral  so sold may be retained by the Agent until the selling price is paid
by the purchaser thereof, but the Agent shall not incur any liability in case of
the failure of such purchase to take up and pay for the  Collateral so sold and,
in the case of such failure, such Collateral may again be sold upon like notice.

(c) Special  Provisions  Relating to Sales of Securities.  The Debtor recognizes
that  the  Agent  may be  unable  to  effect  a  public  sale  of any or all the
Collateral  constituting a "security" (as such term is defined in the Securities
Act) by reason of  certain  prohibitions  contained  in the  Securities  Act and
applicable state securities laws or otherwise, and may be compelled to resort to
one or more private sales thereof to a restricted  group of purchasers that will
be obliged to agree,  among other things,  to acquire such  securities for their
own account for  investment  and not with a view to the  distribution  or resale
thereof.  The Debtor  acknowledges  and agrees  that any such  private  sale may
result in prices and other terms less  favorable than if such sale were a public
sale and, notwithstanding such circumstances,  agrees that any such private sale
shall be deemed to have been made in a commercially reasonable manner. The Agent
shall be under no obligation to delay a sale of any of Collateral constituting a
security  for the  period of time  necessary  to permit  the  issuer  thereof to
register  such  securities  for public sale under the  Securities  Act, or under
applicable state securities laws, even if such issuer would agree to do so.

Section 5.05.  Rights of Purchasers.  Upon any sale of the  Collateral  (whether
public or  private),  the Agent  shall  have the right to  deliver,  assign  and
transfer  to the  purchaser  thereof  the  Collateral  so sold.  Each  purchaser
(including  the  Agent)  at any such  sale  shall  hold the  Collateral  so sold
absolutely,  free from any claim or right of whatever kind, including any equity
or right of redemption of the Debtor who, to the extent permitted by law, hereby
specifically waives all rights of redemption, including, without limitation, any
right to redeem the Collateral  under Section 9-506 of the UCC, and any right to
a judicial or other stay or approval  which it has or may have under any law now
existing or hereafter adopted.

Section 5.06.     Additional Rights of the Agent.

(a) Right to Maintain Proceedings.  The Agent (i) shall have the right and power
to institute and maintain such suits and proceedings as it may deem  appropriate
to protect and enforce the rights  vested in it by this  Security  Agreement and
(ii) may proceed by suit or suits at law or in equity to enforce such rights and
to foreclose  upon the  Collateral and to sell all or, from time to time, any of
the   Collateral   under  the  judgment  or  decree  of  a  court  of  competent
jurisdiction.

(b)  Appointment  of  Receiver.  The Agent  shall,  to the extent  permitted  by
applicable law,  without notice to the Debtor to any party claiming  through the
Debtor,  without regard to the solvency or insolvency at such time of any Person
then liable for the  payment of any of the  Obligations,  without  regard to the
then value of the Collateral and without requiring any bond from any complainant
in such  proceedings,  be entitled as a matter of right to the  appointment of a
receiver  or  receivers  (who may be the  Agent) of the  Collateral  or any part
thereof,  pending  such  proceedings,  with such powers as the court making such
appointment  shall  confer,  and to the  entry  of an order  directing  that the
profits, revenues and other income of the property constituting the whole or any
part of the Collateral be segregated,  sequestered and impounded for the benefit
of the Agent,  and the Debtor  irrevocably  consents to the  appointment of such
receiver or receivers and to the entry of such order.

(c) No Duty to  Exercise  Rights.  In no event  shall the Agent have any duty to
exercise any rights or take any steps to preserve the rights of the Agent in the
Collateral,  nor shall the Agent be liable to the Debtor or any other Person for
any loss caused by the Agent's failure to meet any obligation imposed by Section
9-207 of the UCC or any successor provision. Without limiting the foregoing, the
Agent  shall be deemed to have  exercised  reasonable  care in the  custody  and
preservation  of the  Collateral in its possession if the Collateral is accorded
treatment  substantially equal to that which the Agent accords its own property,
it being understood that the Agent shall not have any duty or responsibility for
(i) ascertaining or taking action with respect to calls, conversions, exchanges,
maturities,  tenders or other matters relative to any Collateral, whether or not
the Agent has or is deemed to have knowledge of such matters, or (ii) taking any
necessary  steps to preserve  rights  against any  parties  with  respect to any
Collateral.

Section 5.07.     Remedies Not Exclusive, etc.

(a) Remedies Not Exclusive. No remedy conferred upon or reserved to the Agent in
this  Security  Agreement  is intended to be  exclusive  of any other  remedy or
remedies,  but every such remedy shall be cumulative and shall be in addition to
every other  remedy  conferred  herein or now or  hereafter  existing at law, in
equity or by statute.

(b)  Restoration  of Rights.  If the Agent shall have  proceeded  to enforce any
right,  remedy or power under this Security Agreement and the proceeding for the
enforcement  thereof shall have been discontinued or abandoned for any reason or
shall have been  determined  adversely  to the  Agent,  the Debtor and the Agent
shall,   subject  to  any  determination  in  such  proceeding,   severally  and
respectively  be  restored  to their  former  positions  and  rights  under this
Security Agreement,  and thereafter all rights, remedies and powers of the Agent
shall continue as though no such proceedings had been taken.

(c)  Enforcement.  All rights of action  under this  Security  Agreement  may be
enforced by the Agent without the  possession of any  instrument  evidencing any
Obligation or the production  thereof at any trial or other proceeding  relative
thereto, and any suit or proceeding  instituted by the Agent shall be brought in
its name and any judgment shall be held as part of the Collateral.

Section 5.08.     Waiver and Estoppel.

(a) No Actions to Impede Sale of Collateral. The Debtor agrees, to the extent it
may lawfully do so, that it will not at any time in any manner  whatsoever claim
or take the benefit or advantage of any appraisal,  valuation,  stay, extension,
moratorium,  turnover or redemption  law, or any law permitting it to direct the
order in which the  Collateral  shall be sold,  now or at any time  hereafter in
force  which  may  delay,   prevent  or  otherwise  affect  the  performance  or
enforcement  of this  Security  Agreement,  and  hereby  waives  all  benefit or
advantage of all such laws. The Debtor covenants that it will not hinder,  delay
or impede  the  execution  of any power  granted  to the Agent in this  Security
Agreement, any Assignment of Federal Contract or any other Credit Document.

(b) Collateral Sold As An Entirety. The Debtor, to the extent it may lawfully do
so, on behalf of itself and all who claim through or under it, including without
limitation any and all  subsequent  creditors,  vendees,  assignees and lienors,
waives  and  releases  all  rights to demand or to have any  marshalling  of the
Collateral upon any sale, whether made under any power of sale granted herein or
pursuant to judicial  proceedings or under any foreclosure or any enforcement of
this Security Agreement,  and consents and agrees that all of the Collateral may
at any such sale be offered and sold as an entirety.

(c) Waiver of  Notices.  The Debtor  waives,  to the  extent  permitted  by law,
presentment,  demand,  protest  and any notice of any kind  (except  the notices
expressly required hereunder) in connection with this Security Agreement and any
action taken by the Agent with respect to the Collateral.

Section 5.09.     Power of Attorney; Powers Coupled With An Interest.

(a) Power of Attorney.  Without limiting any other right granted hereunder,  the
Debtor hereby irrevocably constitutes and appoints the Agent, with full power of
substitution,  as its true and  lawful  attorney-in-fact  with full  irrevocable
power and  authority in the place and stead of the Debtor and in the name of the
Debtor  or in its  own  name,  from  time  to  time  in the  Agent's  reasonable
discretion,  for the  purpose  of  carrying  out  the  terms  of  this  Security
Agreement,  to take any and all  appropriate  action and to execute  any and all
documents and instruments  which may be necessary or desirable to accomplish the
purpose of this Security  Agreement and,  without limiting the generality of the
foregoing,  hereby gives the Agent the power and right, on behalf of the Debtor,
without notice to or assent by the Debtor, to do the following:

     (i)  to  pay  or  discharge  taxes,  liens,  security  interests  or  other
     encumbrances levied or placed on or threatened against the Collateral;

(ii) to effect  any  repairs  or any  insurance  called for by the terms of this
Security  Agreement or any other Credit Document,  and to pay all or any part of
the premiums therefor and the costs thereof;

(iii) upon the occurrence and  continuance of any Event of Default and otherwise
to the  extent  provided  in this  Security  Agreement,  (A) to direct any party
liable for any payment  under any of the  Collateral  to make payment of any and
all moneys due and to come due thereunder  directly to the Agent or as the Agent
shall direct,  (B) to receive  payment of and receipt for, and to demand and sue
for, any and all moneys,  claims and other  amounts due and to become due at any
time in respect of or arising out of the Collateral, (C) to sign and indorse and
receive,  take, assign and deliver, any checks,  notes,  drafts,  negotiable and
non-negotiable  instruments,  any invoices,  freight or express bills,  bills of
lading,  storage or warehouse  receipts,  drafts against  debtors,  assignments,
verifications  and  notices in  connection  with  accounts  and other  documents
relating to the  Collateral,  (D) to  commence,  settle,  compromise,  compound,
prosecute,  defend or adjust any claim,  suit, action or proceeding with respect
to, or in connection  with, the  Collateral,  (E) to sell,  transfer,  assign or
otherwise  deal in or with the  Collateral  or any part  thereof,  as fully  and
effectively  as if the Agent were the absolute  owner  thereof and (F) to do, at
its option,  but at the expense of the Debtor, at any time or from time to time,
all acts and things  which the Agent deems  necessary  to  protect,  preserve or
realize upon the Collateral and the Agent's security interest therein,  in order
to effect the intent of this Security Agreement, all as fully and effectively as
the Debtor might do.

(b) Powers Coupled With an Interest.  All authorizations and agencies granted or
provided  herein with respect to the  Collateral,  including the powers  granted
under clause (a) of this Section 5.9, are irrevocable and powers coupled with an
interest.

Section 5.10. Certain Provisions Relating to Securities.  Solely with respect to
any Collateral  constituting a "security" (as defined in the Securities Act), if
an Event of Default shall have occurred and be continuing,  all such  securities
(as defined in the Securities Act)  constituting a part of the Collateral shall,
at the  request  of the  Agent,  be  registered  in the name of the Agent or its
nominee,  and the Agent or its nominee may  thereafter  exercise (i) all voting,
corporate and other rights,  powers and privileges pertaining to such Collateral
at any meeting of shareholders of the issuer thereof or otherwise,  and (ii) any
and all  rights of  conversion,  exchange,  subscription  and any other  rights,
privileges or options  pertaining to such  Collateral as if it were the absolute
owner  thereof  (including,  without  limitation,  the right to  exchange at its
discretion  any  and  all  such  Collateral  upon  the  merger,   consolidation,
reorganization, recapitalization or other fundamental change in the structure of
any such  issuer,  or upon the exercise by the Debtor or the Agent of any right,
privilege or option pertaining to such Collateral,  and in connection therewith,
the right to deposit and deliver any and all such Collateral with any committee,
depositary, transfer agent, registrar or other designated agency upon such terms
and conditions as it may determine), all without liability except to account for
property  actually  received  by it and except as  provided  in  Section  5.6(c)
hereof,  but the Agent  shall  have no duty to the Debtor to  exercise  any such
right, privilege or option and shall not be responsible for any failure to do so
or delay in so doing.

     Section 5.11.  Application of Monies. The proceeds of any sale of, or other
     realization upon, all or any part of the Collateral shall be applied by the
     Agent in the following order of priority:

                  first,  to  payment  of the  expenses  of such  sale or  other
realization,  including reasonable  compensation to the Agent and its agents and
counsel,  and all  expenses,  liabilities  and advances  incurred or made by the
Agent, its agents and counsel in connection  therewith or in connection with the
care, safekeeping or otherwise of any or all of the Collateral;

     second,  to  payment  of the  Obligations,  in such  order as the Agent may
     elect; and

                  third, any surplus then remaining shall be paid to the Debtor,
or its  successors  or assigns,  or to  whomsoever  may be lawfully  entitled to
receive the same (including  pursuant to Section 9-504(1)(C) of the UCC) or as a
court of competent jurisdiction may direct.

ARTICLE VI.

                                              MISCELLANEOUS

Section 6.01. Notices. All notices, requests and other communications to a party
hereunder  shall be in writing  and shall be given to such party at its  address
set forth on the  signature  page hereof or such other address as such party may
hereafter  specify for that  purpose by notice to the other.  Each such  notice,
request or other  communication shall be effective (i) in the case of telephonic
notice (to the extent  expressly  permitted  hereunder),  when made, (ii) in the
case of notice delivered by overnight  express  courier,  one Business Day after
the Business Day such notice was delivered to such courier, (iii) in the case of
notice  delivered by first class mail, three Business Days after being deposited
in the mail,  postage  prepaid,  return receipt  requested,  (iv) in the case of
notice by hand,  when  delivered,  or (v) in the case of notice by any customary
means of telecommunication, when sent provided confirmation of receipt or answer
back has been  received,  in each  case if  addressed  to any  party  hereto  as
provided  herein.  Rejection or refusal to accept,  or the  inability to deliver
because of a changed address of which no notice was given,  shall not affect the
validity of notice given in accordance with this section.

Section 6.02.  No Waiver;  Cumulative  Remedies.  The Agent shall not by any act
(except by a written  instrument  pursuant  to Section  6.3 hereof) be deemed to
have waived any right or remedy hereunder. No failure to exercise, nor any delay
in exercising,  on the part of the Agent any right, power or privilege hereunder
shall operate as a waiver thereof.  No single or partial  exercise of any right,
power or  privilege  hereunder  shall  preclude  any other or  further  exercise
thereof or the exercise of any other right, power or privilege.  A waiver by the
Agent  of any  right  or  remedy  hereunder  on any one  occasion  shall  not be
construed as a bar to any right or remedy which the Agent would  otherwise  have
on any future occasion.  The rights and remedies herein provided are cumulative,
may be  exercised  singly or  concurrently  and are not  exclusive  of any other
rights or remedies provided by law.

Section 6.03.  Amendments  and Waivers.  None of the terms or provisions of this
Security Agreement may be amended,  supplemented or otherwise modified except by
a written  instrument  executed by the Debtor and the Agent;  provided  that any
provision of this  Security  Agreement may be waived by the Agent in a letter or
agreement  executed by the Agent or by telex or facsimile  transmission from the
Agent.

Section 6.04.  Successors and Assigns. The provisions of this Security Agreement
shall be binding  upon and inure to the benefit of the parties  hereto and their
respective  successors and assigns;  provided,  however, that the Debtor may not
assign or transfer any of its rights or obligations  hereunder without the prior
written consent of the Agent.

     Section 6.05.  Governing Law. THIS SECURITY  AGREEMENT SHALL BE GOVERNED BY
     AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE  COMMONWEALTH OF VIRGINIA,
     OTHER THAN ITS LAWS RESPECTING  CHOICE OF LAW OTHER THAN THOSE CONTAINED IN
     THE UCC.

Section 6.06.     Limitation by Law; Severability.

(a) All rights,  remedies and powers provided in this Security  Agreement may be
exercised  only to the extent  that the  exercise  thereof  does not violate any
applicable  provision of law, and all the provisions of this Security  Agreement
are intended to be subject to all applicable  mandatory  provisions of law which
may be controlling  and to be limited to the extent  necessary so that they will
not render this Security Agreement  invalid,  unenforceable in whole or in part,
or not entitled to be recorded,  registered or filed upon the  provisions of any
applicable law.

(b) If any provision hereof is invalid and  unenforceable  in any  jurisdiction,
then, to the fullest extent  permitted by law, (i) the other  provisions  hereof
shall  remain  in full  force  and  effect  in such  jurisdiction  and  shall be
liberally  construed in favor of the Agent in order to carry out the  intentions
of the parties  hereto as nearly as may be possible and (ii) the  invalidity  or
unenforceability  of any provision hereof in any  jurisdiction  shall not affect
the validity or enforceability of such provision in any other jurisdiction.

Section  6.07.  Counterparts.  This  Security  Agreement  may be executed in any
number of counterparts and by different parties hereto on separate counterparts,
each complete set of which, when so executed and delivered by all parties, shall
be an original,  but all such counterparts shall together constitute but one and
the same instrument.

Section 6.08. Expenses of the Agent. The Debtor shall pay to the Agent from time
to time upon demand,  all of the costs and expenses incurred by the Agent or any
Lender (including,  without limitation, the reasonable fees and disbursements of
counsel  and any  amounts  payable  by the  Agent or any  Lender to any of their
respective   agents)  (i)  arising  in  connection   with  the   administration,
modification, amendment, waiver or termination of this Security Agreement or any
document or agreement  contemplated hereby or any consent or waiver hereunder or
thereunder  or (ii)  incurred  in  connection  with the  administration  of this
Security  Agreement,  or any document or agreement  contemplated  hereby,  or in
connection  with the  administration,  sale or other  disposition  of Collateral
hereunder  or  under  any  document  or  agreement  contemplated  hereby  or the
preservation,  protection or defense of the rights of the Agent or any Lender in
and to the Collateral.

Section  6.09.  Indemnification.   The  Debtor  shall  at  all  times  hereafter
indemnify, hold harmless and, on demand, reimburse the Agent and the Lenders and
their  respective  subsidiaries,   affiliates,  successors,  assigns,  officers,
directors,   employees  and  agents,  and  their  respective  heirs,  executors,
administrators, successors and assigns (all of the foregoing parties, including,
but not limited to, the Agent, being hereinafter collectively referred to as the
"Indemnities" and individually as an "Indemnitee") from, against and for any and
all liabilities,  obligations,  claims, damages, actions,  penalties,  causes of
action, losses, judgments, suits, costs, expenses and disbursements,  including,
without  limitation,  attorney's  fees  (any  and  all  of the  foregoing  being
hereinafter  collectively referred to as the "Liabilities" and individually as a
"Liability")  which  the  Indemnitees,  or  any  of  them,  might  be or  become
subjected, by reason of, or arising out of the preparation, execution, delivery,
modification,  administration  or enforcement  of, or performance of the Agent's
rights  under,  this  Security  Agreement or any other  document,  instrument or
agreement  contemplated  hereby or executed in  connection  herewith;  provided,
however, that the Debtor shall not be liable to any Indemnitee for any Liability
caused solely by the gross negligence or willful  misconduct of such Indemnitee.
In no event shall any  Indemnitee,  as a condition to enforcing its rights under
this Section 6.9 or  otherwise,  be obligated to make a claim  against any other
Person (including,  without  limitation,  the Agent) to enforce its rights under
this Section 6.9.

Section 6.10.  Termination;  Survival.  This Security  Agreement shall terminate
when the security interests granted hereunder have terminated and the Collateral
has been  released as  provided  in Section  2.6;  provided,  however,  that the
obligations  of the Debtor under Section 4.22 and the provisions of this Article
6 shall survive any such termination.

Section  6.11.  Judicial  Proceedings;   Waiver  of  Jury  Trial.  Any  judicial

                         ASSIGNMENT OF FEDERAL CONTRACT


                  This  ASSIGNMENT OF FEDERAL  CONTRACT,  dated as of _____,  __
(the  "Agreement"),  is  made  by  HAGLER  BAILLY  SERVICES,  INC.,  a  Delaware
corporation (the "Assignor"), in favor of NATIONSBANK,  N.A., a national banking
association (the "Agent"), in its capacity as Agent for the lenders from time to
time a party to the  Revolving  Credit  Agreement  (as  defined in the  Security
Agreement referred to below).

                                               W I T N E S S E T H:

                  WHEREAS,   the  Assignor  has  secured   certain   obligations
undertaken  by Hagler  Bailly,  Inc.  pursuant to the  provisions  of a Security
Agreement,  dated as of  ___________________,  ____ (as the same may be amended,
supplemented or otherwise modified from time to time, the "Security Agreement"),
by and between the Assignor and the Agent; and

                  WHEREAS,  the  Assignor  is a party to,  and from time to time
will  become  entitled  to  receive  moneys  under and by  virtue  of, a certain
contract  with,  involving or for the benefit of the United States of America or

Assignor and the Government on ________ __, 19__ (which contract,  together with
all additions, change orders, supplements, amendments, renewals, extensions, and
modifications  thereto now or hereafter in effect, are hereinafter  collectively
called the "Contract"); and

                  WHEREAS,  pursuant to the Security Agreement, the Assignor has
undertaken to effectuate the  assignment(s)  and other actions  contemplated  by
this Agreement.

                  NOW,  THEREFORE,  in  consideration  of the premises and other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the Assignor covenants and agrees as follows:

         1. Incorporation By Reference. The provisions of the Security Agreement
are  incorporated  herein by  reference,  and the terms  defined in the Security
Agreement are used herein with the same meanings.

         2.  Representations.  The Assignor represents and warrants to the Agent
that (a) the Contract is legal,  valid and binding on the  Assignor  and, to its
knowledge,  the other parties thereto,  is in full force and effect,  and is not
evidenced  by any  chattel  paper or  instrument,  (b) upon due  filing  of this
Agreement,  together  with a Notice of Assignment  substantially  in the form of
Appendix A hereto with the authorized representative, the execution and delivery
of this Agreement does not violate and is not in conflict with the provisions of
the  Contract,  (c) there has been no default on the part of the Assignor or any
other party to the Contract, (d) the Assignor has made no previous assignment of
the  Contract to any person and knows of no fact or defense that will render the
moneys due or to be due  thereunder  uncollectible,  (e) no financing  statement
covering  the  Contract  is on  file  in  any  public  office  except  financing
statements in favor of the Agent,  (f) no set-off or  counterclaim to any moneys
due or to become  due  under the  Contract  exists  on the date  hereof,  and no
agreement  has been made with any person  under which any  deduction or discount
may be claimed,  and (g) the address of the office where the Assignor  keeps its
records concerning the Contract is ____________________.

         3. Collateral. As security and collateral for the payment of all of the
Obligations  (defined in the Security  Agreement)  and for  performance  of, and
compliance  with,  by the  Assignor,  all of the terms,  covenants,  conditions,
stipulations,  and  agreements  contained in this  Agreement and in the Security
Agreement,  the Assignor hereby assigns to the Agent,  and grants to the Agent a
lien on and  security  interest  in,  all  moneys  and claims for moneys now and
hereafter  due and to  become  due to the  Assignor  under or by  reason  of the
Contract,  together  with all  cash and  non-cash  proceeds  thereof;  provided,
however,  that nothing  contained  herein shall impose upon the Agent any of the
obligations or liabilities of the Assignor under the Contract.

         4. Covenants. Until payment and performance in full of the Obligations,
the Assignor covenants as follows:

(c) The  Assignor  shall  place  on any and all  vouchers,  invoices,  or  other
instruments demanding payment under the Contract the direction that such payment
is to be made to the Agent in accordance with Section 5 of this Agreement.

(d) The Assignor shall promptly upon request execute,  acknowledge,  and deliver
any  notice,  financing  statement,   renewal,   affidavit,   deed,  assignment,
continuation statement,  security agreement,  certificate,  or other document as
the  Agent  may  require  in  order to  perfect,  preserve,  maintain,  protect,
continue, and/or extend the assignment, lien, and security interest of the Agent
under this  Agreement and its priority.  The Assignor  shall pay to the Agent on
demand all taxes,  costs, and expenses  incurred by the Agent in connection with
the  preparation,  execution,  recording,  and  filing of any such  document  or
instrument  mentioned  aforesaid,  and such taxes,  costs,  and  expenses  shall
constitute  and become a part of the  Obligations.  A carbon,  photographic,  or
other  reproduction  of  a  security  agreement  or  a  financing  statement  is
sufficient as a financing statement.

(e) The Assignor shall fully,  promptly,  and faithfully comply with and perform
its  obligations  and duties  under the  Contract in  accordance  with the terms
thereof and will make no changes or  amendments  to the Contract or terminate or
cancel the  Contract  without the prior  written  consent of the Agent except as
permitted by the Security  Agreement.  In the event that any change,  amendment,
termination  or  cancellation  of  the  Contract  is  made  or  effected  by the
Government,  the Assignor  will  promptly  notify the Agent thereof and promptly
furnish to the Agent a copy of any  document or  agreement  evidencing  any such
change, amendment, termination, or cancellation.

(f)      The Assignor will promptly

     (i) furnish to the Agent all information received by the Assignor affecting
     the moneys due and to become due under the Contract,

     (ii)  inform the Agent of any delay in  performance  of, or claims  made in
     regard to, the Contract, and

(iii) notify the Agent in writing of the failure of any party to the Contract to
perform any of its  obligations  thereunder and any rejection of any performance
rendered by the Assignor under or in connection with the Contract.

(g) The  Assignor  will at all times  keep  accurate  and  complete  records  of
performance  by the Assignor  under the  Contract,  and the Agent and its agents
shall have the right,  during normal business hours and upon reasonable  advance
notice,  to call at the place or places of business of the Assignor at intervals
to be  determined  by the Agent,  and without  hindrance  or delay,  to inspect,
audit,  check,  and make extracts  from the books,  records,  journals,  orders,
receipts,  correspondence,  and other data  relating  to the  Contract or to any
other transactions between the parties hereto related to the Contract.

         5. Payments. The Assignor hereby authorizes,  empowers, and directs the
Government to draw all checks,  drafts,  or other  instruments  representing the
payments of money due the Assignor under the Contract  (herein called the "Items
of Payment") to the order of  NationsBank,  N.A.,  assignee of Assignor,  and to
send  the  same  (i)  if by  mail,  to ,  (ii)  if by  electronic  transfer,  to
NationsBank, N.A. for the account of ________________, Bank Account #__________,
Agent ABA#_________,  or (iii) if by wire transfer, to NationsBank, N.A. for the
account of  _________________________,  Bank Account #_______,  ABA#___________.
If, despite this  direction,  any  instruments or checks  representing  payments
should be delivered to the Assignor,  the Assignor will immediately  endorse and
deliver such  instruments or checks to the order of the Agent. The Assignor does
hereby  irrevocably  (subject  to  revocation  with the  consent  of the  Agent)
designate and appoint (which appointment is coupled with an interest) the Agent,
and the Agent's  successors in interest by operation of law, the Assignor's true
and  lawful  attorney  with  power  irrevocable  for  the  Assignor  and  in the
Assignor's  name,  place,  and  stead,  but at the sole cost and  expense of the
Assignor,  to receive,  endorse,  and collect all Items of Payment,  and to ask,
demand,  receive,  receipt,  and give acquittances for any and all amounts which
may be payable  or which  become due and  payable  by the  Government  under the
Contract,  and in the Agent's  discretion to file any claim or to take any other
action  or  proceeding,  either  in the  Agent's  own name or in the name of the
Assignor or otherwise,  which to the Agent or any successor in interest  thereof
may seem  necessary  or  desirable in order to collect or endorse the payment of
any and all amounts now due or owing or which may  hereafter be or become due or
owing on account of the  Contract.  All Items of Payment  received  by the Agent
pursuant  hereto  which are  finally  paid in cash or solvent  credits  shall be
applied  against the  Obligations  as provided in the  Security  Agreement.  Any
portion of the Items of Payment  which the Agent elects not to so apply shall be
paid over to the  Assignor  or to  whomsoever  shall be entitled  thereto  under
applicable  law,  including  pursuant  to  Section  9-504(1)(C)  of the  Uniform
Commercial Code of the Commonwealth of Virginia.

         6.  No  Waiver.   Neither  this  Agreement  nor  any  term,  condition,
representation,  warranty, covenant, or agreement hereof may be changed, waived,
discharged,  or terminated  orally,  but only by an instrument in writing by the
party against whom such change, waiver, discharge, or termination is sought.

         7. Governing law. THIS AGREEMENT  SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE  WITH THE LAWS OF THE  COMMONWEALTH  OF VIRGINIA,  WITHOUT  REGARD TO
PRINCIPLES OF CONFLICTS OF LAWS.

         8. Gender.  Whenever used herein, the singular number shall include the
plural,  the plural the singular,  and the use of the  masculine,  feminine,  or
neuter gender shall include all genders.

         9.  Counterparts.  This  Agreement  may be  executed  in any  number of
duplicate  originals,  each of  which  shall  be an  original  but all of  which
together shall constitute one and the same instrument.

         10. Paragraph  Headings.  The paragraph  headings of this Agreement are
for  convenience  only and  shall not limit or  define  the  provisions  of this
Agreement.

                                            SECURITY INTERESTS

Section  2.01.  Grant of  Security  Interests.  To secure  the due and  punctual
payment of all Obligations,  howsoever  created,  arising or evidenced,  whether
direct or indirect,  absolute or contingent, now or hereafter existing or due or
to become  due,  whether at  maturity  or upon  acceleration  or  otherwise,  in
accordance with the terms thereof and to secure the due and punctual performance
of all of the  Obligations  and in order to induce the Agent and the  Lenders to
enter into the Revolving  Credit Agreement and the other Credit  Documents,  the
Debtor hereby pledges,  assigns,  delivers,  conveys and transfers to the Agent,
for the ratable benefit of the Lenders, and grants to the Agent, for the ratable
benefit of the Lenders, a first priority and continuing security interest in and
lien on, all of the  Debtor's  right,  title and  interest  in, to and under the
following, whether now existing or hereafter acquired (the "Collateral"):

(i)      all Receivables;

(ii)     all Other Intangibles;

(iii)    all Equipment;

(iv)     all Inventory;

(v) to the  extent  not  included  in the  foregoing,  all  securities  (whether
certificated or uncertificated)  and all financial assets,  whether now existing
or hereafter arising, including, without limitation, all capital stock issued by
any Person and held by Debtor,  and all  partnership  interests,  whether in the
nature of a joint venture,  limited liability company member's interest,  master
limited partnership, teaming arrangement or otherwise;

(vi) to the extent not included in the foregoing,  all other personal  property,
whether  tangible or intangible,  and wherever located whether within or outside
of the United  States,  including,  but not  limited  to,  the  balance of every
deposit  account now or hereafter  existing of the Debtor with any bank or other
financial  institution and all monies of the Debtor and all rights to payment of
money of the Debtor;

(vii) to the extent not  included  in the  foregoing,  all  books,  ledgers  and
records and all computer  programs,  tapes,  discs, punch cards, data processing
software,  transaction  files,  master  files and  related  property  and rights
(including computer and peripheral equipment) necessary or helpful in enforcing,
identifying or establishing any item of Collateral; and

(viii) to the extent not otherwise included, all Proceeds and products of any or
all of the foregoing, whether existing on the date hereof or arising hereafter;

provided,  however,  notwithstanding  anything to the contrary contained herein,
the  Debtor is not  assigning,  pledging  or  otherwise  encumbering  under this
Security Agreement its interests in any Federal Contract to which it is a party,
or in accounts or receivables due to Debtor under such Federal Contract,  to the
extent,  but only to the extent,  such assignment,  pledge or other  encumbrance
would  breach or violate or would cause Debtor to breach or violate such Federal
Contract or statutes or regulations applicable thereto, it being understood that
this proviso does not apply to, or in any way limit, Debtor's assignment, pledge
or encumbrance of Proceeds of all Federal Contracts to which it is a party.

Section  2.02.  Continuing  Liability  of the  Debtor.  Anything  herein  to the
contrary notwithstanding,  the Debtor shall remain liable to observe and perform
all the  terms and  conditions  to be  observed  and  performed  by it under any
contract,   agreement,   warranty  or  other  obligation  with  respect  to  the
Collateral;  and  shall do  nothing  to impair  the  security  interests  herein
granted.  The Agent shall not have any  obligation  or liability  under any such
contract,  agreement, warranty or obligation by reason of or arising out of this
Security  Agreement  or the receipt by the Agent of any payment  relating to any
Collateral,  nor shall the Agent be  required  to perform or fulfill  any of the
obligations of the Debtor with respect to the Collateral, to make any inquiry as
to the nature or sufficiency of any payment received by it or the sufficiency of
the  performance  of any party's  obligations  with  respect to any  Collateral.
Furthermore,  the  Agent  shall not be  required  to file any claim or demand to
collect any amount due or to enforce the performance of any party's  obligations
with respect to, the Collateral.

Section 2.03.     Sales and Collections.

(a) Sales of  Inventory  in the  Ordinary  Course  of  Business.  The  Debtor is
authorized (i) to sell in the ordinary course of its business for fair value and
on an  arm's-length  basis  any of its  Inventory  normally  held by it for such
purpose and (ii) to use and consume, in the ordinary course of its business, any
raw materials,  supplies and materials normally held by it for such purpose. The
Agent may, upon the occurrence of any Event of Default, without cause or notice,
curtail or terminate such authority at any time.

(b) Collection of Receivables. The Debtor is authorized to collect amounts owing
to it with respect to the Collateral, except as otherwise provided in connection
with the Assignment of Federal Contract, if any as provided herein. However, the
Agent may, upon and during the continuance of an Event of Default or a Potential
Event of Default, notify Account Debtors obligated to make payments under any or
all Receivables or Other  Intangibles that the Agent has a security  interest in
such Collateral and that payments shall be made directly to the Agent.  Upon the
request of the Agent upon and during the continuance of an Event of Default or a
Potential  Event of Default,  as the case may be, the Debtor will so notify such
Account  Debtors  and  will  execute  such  contract  assignments,   notices  of
assignment or other  documents as may be required by such Account  Debtors.  The
Debtor will use all  reasonable  efforts to cause each Account  Debtor to comply
with the foregoing  instruction.  In furtherance  of the  foregoing,  the Debtor
authorizes the Agent upon and during the continuance of an Event of Default or a
Potential  Event of Default (i) to ask for,  demand,  collect,  receive and give
acquittances  and  receipts  for any and all amounts due and to become due under
any Collateral and in the name of the Debtor or its own name or otherwise,  (ii)
to  take  possession  of,  endorse  and  collect  any  checks,   drafts,  notes,
acceptances  or other  instruments  for the  payment  of  monies  due  under any
Collateral  and (iii) to file any claim or take any other action in any court of
law or equity or  otherwise  which it may deem  appropriate  for the  purpose of
collecting  any  amounts  due under any  Collateral.  The  Agent  shall  have no
obligation  to obtain or record any  information  relating to the source of such
funds or the obligations in respect of which payments have been made.

Section 2.04.     Segregation of Proceeds.

(a) Cash Collateral  Account  Maintained by Agent. Upon an Event of Default or a
Potential  Event of  Default,  the Agent shall have the right at any time during
the  continuance  thereof to cause to be opened and  maintained at the office of
the Agent in McLean,  Virginia a  non-interest  bearing  bank account (the "Cash
Collateral  Account") which will contain only Proceeds.  Any "cash proceeds" (as
such term is defined  in  Section  9-306(1)  of the UCC)  received  by the Agent
directly from Account  Debtors  obligated to make payments under  Receivables or
Other Intangibles  pursuant to Section 2.3 hereof or from the Debtor pursuant to
clause (b) of this Section 2.4,  whether  consisting of checks,  notes,  drafts,
bills of exchange, money orders,  commercial paper or other Proceeds received on
account of any  Collateral,  shall be promptly  deposited in the Cash Collateral
Account, and until so deposited shall be held in trust for the Agent as property
of the  Agent  and shall not be  commingled  with any  funds of the  Debtor  not
constituting  Proceeds  of  Collateral.  The name in which  the Cash  Collateral
Account is carried shall clearly  indicate that the funds deposited  therein are
the  property  of the  Debtor,  subject to the  security  interest  of the Agent
hereunder. Such Proceeds, when deposited,  shall continue to be security for the
Obligations   and  shall  not  constitute   payment  thereof  until  applied  as
hereinafter  provided.  The Agent shall have sole  dominion and control over the
funds deposited in the Cash Collateral Account,  and such funds may be withdrawn
therefrom only by the Agent.

(b) Deposit of  Proceeds  by the Debtor.  Upon notice by the Agent to the Debtor
that the Cash  Collateral  Account has been  opened,  the Debtor shall cause all
cash  Proceeds  collected  by it to be  delivered  to the Agent  forthwith  upon
receipt,  in the original  form in which  received  (with such  endorsements  or
assignments as may be necessary to permit collection  thereof by the Agent), and
for such  purpose the Debtor  hereby  irrevocably  authorizes  and  empowers the
Agent,  its officers,  employees and  authorized  agents to endorse and sign the
name of the Debtor on all checks, drafts, money orders or other media of payment
so delivered,  and such endorsements or assignments shall, for all purposes,  be
deemed to have been made by the Debtor prior to any  endorsement  or  assignment
thereof by the Agent.  The Agent may use any  convenient or customary  means for
the purpose of collecting  such checks,  drafts,  money orders or other media of
payment.

Section 2.05.  Verification  of  Receivables.  The Agent shall have the right to
make test  verifications of Receivables in any reasonable manner and through any
medium that it considers  advisable,  and the Debtor  agrees to furnish all such
assistance and  information  as the Agent may  reasonable  require in connection
therewith.  The Debtor at its expense will cause its chief financial  officer to
furnish to the Agent at any reasonable  time and from time to time promptly upon
the Agent's reasonable request,  the following reports:  (i) a reconciliation of
all Receivables, (ii) an aging of all Receivables, (iii) trial balances and (iv)
a test verification of such Receivables as the Agent may request.

Section 2.06.     Release of Collateral.

(a) Security  Interest of Agent Ceases Upon Permitted  Dispositions.  The Debtor
may sell or realize upon or transfer or otherwise  dispose of Collateral only to
the extent permitted by Section 4.13, and the security interests of the Agent in
such  Collateral so sold,  realized upon or disposed of (but not in the Proceeds
arising from such sale, realization or disposition) shall cease immediately upon
such sale, realization or disposition, without any further action on the part of
the Agent.  The Agent,  if requested in writing by the Debtor but at the expense
of the Debtor,  is hereby  authorized  and  instructed to deliver to the Account
Debtor or the purchaser or other transferee of any such Collateral a certificate
stating  that the Agent no longer  has a  security  interest  therein,  and such
Account Debtor or such purchaser or other  transferee  shall be entitled to rely
conclusively on such certificate for any and all purposes.

(b) Filing of  Termination  Statements.  Upon the  payment in full of all of the
Obligations  and if  there  is no  commitment  by any  Lender  to  make  further
advances,  incur obligations or otherwise give value, the Agent will (as soon as
reasonably  practicable  after receipt of notice from the Debtor  requesting the
same but at the  expense  of the  Debtor)  deliver  to the  Debtor  (i) for each
jurisdiction  in  which a UCC  financing  statement  is on file to  perfect  the
security  interests  granted to the Agent  hereunder,  a  termination  statement
(appropriately  completed)  to the  effect  that the  Agent no  longer  claims a
security interest under such financing statement,  and (ii) such other documents
as  the  Debtor  shall  reasonably  request   evidencing   satisfaction  of  the
Obligations  and the  release  of the  security  interests  granted to the Agent
hereunder.

ARTICLE III.

                                      REPRESENTATIONS AND WARRANTIES

         The Debtor represents and warrants that:

Section 3.01. Title to Collateral.  Except for the security interests granted to
the Agent  pursuant to this  Security  Agreement  and as otherwise  permitted by
Section 6.2(a) of the Revolving Credit  Agreement,  the Debtor is the sole owner
of each item of the Collateral,  having good and marketable title thereto,  free
and clear of any and all Liens.

Section 3.02.     Validity, Perfection and Priority of Security Interests.

(a) By complying  with Section 4.1 hereof,  the Debtor will have created a valid
security  interest in favor of the Agent in all existing  Collateral  and in all
identifiable  Proceeds of such  Collateral,  which security  interest (except in
respect of  Collateral  not located at a facility  identified  on  Schedule  3.7
hereto  and motor  vehicles  for  which the  exclusive  manner of  perfecting  a
security interest therein is by noting such security interest in the certificate
of title in accordance with local law) would be prior to the claims of a trustee
in bankruptcy under Section 544(a) of the Bankruptcy Code. Continuing compliance
by the Debtor  with the  provisions  of Section  4.2 hereof will also (i) create
valid security interests in all Collateral acquired after the date hereof and in
all  identifiable  Proceeds  of such  Collateral  and (ii) cause  such  security
interests in all Collateral and in all Proceeds which are (A) identifiable  cash
Proceeds of  Collateral  covered by  financing  statements  required to be filed
hereunder,  (B)  identifiable  Proceeds  in  which a  security  interest  may be
perfected  by such  filing  under  the UCC and  (C)  any  Proceeds  in the  Cash
Collateral Account to be duly perfected under the UCC, in each case prior to the
claims of a trustee in bankruptcy  under the Bankruptcy  Code (except in respect
of Collateral not located at a facility identified on Schedule 3.5 hereto).

(b) The  security  interests  of the  Agent  in the  Collateral  located  at the
facilities identified on Schedule 3.5 hereto rank first in priority.  Other than
financing   statements  or  other  similar  documents  perfecting  the  security
interests  in favor of the  Agent,  no  financing  statements,  deeds of  trust,
mortgages or similar documents covering all or any part of the Collateral are on
file or of record in any  government  office in any  jurisdiction  in which such
filing or recording  would be  effective to perfect a security  interest in such
Collateral,  nor is any of the Collateral in the possession of any Person (other
than the Debtor) asserting any claim thereto or security interest therein.

Section 3.03.  Enforceability of Receivables and Other Intangibles.  To the best
knowledge of the Debtor,  each  Receivable  and Other  Intangible is a valid and
binding obligation of the related Account Debtor in respect thereof, enforceable
in accordance with its terms,  except as such  enforceability  may be limited by
applicable bankruptcy,  insolvency,  reorganization,  moratorium or similar laws
affecting  the  enforcement  of  creditors'  rights  generally  and  by  general
provisions of equity (regardless of whether such enforceability is considered in
a  proceeding  in equity or at law),  and  complies  with any  applicable  legal
requirements.

Section 3.04.  Place of Business.  Schedule 3.4  correctly  sets forth the chief
executive  office and principal  place of business of the Debtor and the offices
of the Debtor where records  concerning  Receivables  and Other  Intangibles are
kept.

Section 3.05.  Location of  Collateral.  Schedule 3.5  correctly  sets forth the
location of all Equipment and Inventory,  other than rolling stock, aircraft and
goods in transit.  Except as otherwise  specified in Schedule 3.5, all Inventory
and Equipment  has been located at the address  specified on Schedule 3.5 at all
times during the  four-month  period prior to the date hereof while owned by the
Debtor.  All Inventory has been and will be produced in compliance with the Fair
Labor Standards Act, 29 U.S.C.  ss.ss.  201-219,  except for such non-compliance
which could not reasonably be expected to have a material  adverse effect on the
Debtor. No Inventory is evidenced by a negotiable  document of title,  warehouse
receipt  or bill of  lading.  No  non-negotiable  document  of title,  warehouse
receipt or bill of lading has been  issued to any person  other than the Debtor,
and the Debtor has retained possession of all of such non-negotiable  documents,
warehouse receipts and bills of lading. No amount payable under or in connection
with  any  of  the  Collateral  is  evidenced  by  promissory   notes  or  other
instruments.

Section 3.06.  Trade Names.  Schedule 3.6 correctly sets forth any and all trade
names,  division  names,  assumed  names or other  names  under which the Debtor
currently  transacts  business or has transacted  business within the four-month
period prior to the date hereof.

     Section 3.07. Patents and Trademarks. Schedule 3.7 correctly sets forth all
     Patents,  Patent licenses,  Trademarks and Trademark  licenses now owned by
     the Debtor.

ARTICLE IV.

                                                COVENANTS

                  The Debtor covenants and agrees that until all obligations and
liabilities in respect of the Obligations  shall have performed and paid in full

all other action necessary or that the Agent may reasonably request to preserve,
perfect,  confirm and protect the security  interests granted hereby. The Debtor

own cost and expense complete books and records relating to the Collateral which

Debtor may contest any act, rule, regulation,  order, decree or direction in any
reasonable  manner which shall not, in the sole opinion of the Agent,  adversely

identified on Schedule 3.7 hereto,  the first priority of its security  interest
in the Collateral.

Section 4.08. Payment of Taxes. The Debtor will pay promptly when due all taxes,
assessments and governmental charges or levies imposed upon the Collateral or in
respect of its income or  profits  therefrom,  as well as all claims of any kind
(including claims for labor, materials and supplies), except that no such charge
need be paid if (i) the  validity  thereof is being  contested  in good faith by
appropriate  proceedings and (ii) such charge is adequately  reserved against in
accordance  with  generally  accepted  accounting  principles,  as  consistently
applied.

Section 4.09.  Compliance with Terms of Accounts and Contracts.  The Debtor will
perform and comply in all material  respects with all of its  obligations  under
all agreements  relating to the Collateral to which it is a party or by which it

dispose of any of the Collateral,  or attempt, offer or contract to do so except

and which is subject to a first priority security interest in favor of the Agent
therein,  except  as  permitted  by  Section  6.2(a)  of  the  Revolving  Credit
Agreement, or (y) applied to repay the Obligations. The inclusion of Proceeds of
the Collateral under the security interests granted hereby shall not be deemed a
consent by the Agent to any sale or disposition of any Collateral  other than as
permitted by this Section 4.13.

Section 4.14. Further  Identification of Collateral.  The Debtor will furnish to
the Agent from time to time  statements and schedules  further  identifying  and

Section  4.15.  Notices.  The  Debtor  will  advise  the Agent  promptly  and in
reasonable detail (i) of any Lien, security interest,  encumbrance or claim made
or  asserted  against  any of the  Collateral,  other  than,  unless  reasonably
requested  by the Agent,  Liens  permitted  by Section  6.2(a) of the  Revolving
Credit  Agreement,  (ii)  of  any  material  change  in the  composition  of the
Collateral,  and (iii) of the  occurrence  of any other event which would have a
material  adverse  effect on the  aggregate  value of the  Collateral  or on the
security interests granted to the Agent in this Security Agreement.

change in law known to it which (i) adversely  affects or will adversely  affect
the validity,  perfection or priority of the security  interests granted hereby,

Inventory or the  Equipment is located for the purpose of  inspecting  the same,
observing its use or protecting the interests of the Agent therein.

representatives  and advisors to review the operations of the Debtor and perform
the audits and  examinations  as  provided  in Section  6.1(l) of the  Revolving
Credit Agreement.

     maintain the Equipment in good operating condition,  ordinary wear and tear
     excepted.

Section 4.19.     Covenants Regarding Patent and Trademark Collateral.

(a)  Generally.  At  such  time as the  Debtor  shall  acquire  any  Patents  or
Trademarks,  it will comply with the terms,  covenants  and  warranties  of this
Section 4.19.

(b) Continued Use of Trademark.  The Debtor (either itself or through licensees)
will, unless the Debtor shall reasonably determine,  after consultation with the
Agent,  that a Trademark  is of  negligible  economic  value to the Debtor,  (i)
continue  to use each  Trademark  on each  and  every  Trademark  class of goods
applicable  to its current  products  and  services as  reflected in its current
catalogs,  brochures and price lists in order to maintain each Trademark in full
force and free from any claim of  abandonment  for non-use,  (ii) maintain as in
the past the quality of products  and  services  offered  under each  Trademark,
(iii) employ each Trademark with the appropriate  notice of  registration,  (iv)
not adopt or use any mark which is confusingly  similar to a colorable imitation
of any Trademark and (v) not (and not permit any licensee or sublicensee thereof
to) do any act or knowingly  omit to do any act whereby any Trademark may become
invalidated.

(c) No  Abandonment.  The Debtor will not,  unless the Debtor  shall  reasonably
determine,  after  consultation  with the Agent,  that a Patent is of negligible
economic  value to the  Debtor,  do any act,  or  knowingly  omit to do any act,
whereby any Patent may be abandoned or dedicated.

(d) Notice of Abandonment or Adverse Determinations. The Debtor shall notify the
Agent  immediately if it knows,  or has reason to know,  that any application or
registration  relating  to any  Patent or  Trademark  may  become  abandoned  or
dedicated,  or of any adverse determination or development  (including,  without
limitation,  the institution of, or any such determination or development in any
proceeding  in the United  States  Patent and  Trademark  Office or any court of
tribunal in any  country)  regarding  the  Debtor's  ownership  of any Patent or
Trademark, its right to register the same or keep and maintain the same.

(e) Filings After Notice to Agent.  In no event shall the Debtor,  either itself
or through any agent,  employee,  licensee or designee,  file an application for
registration  of any  Patent or  Trademark  with the  United  States  Patent and
Trademark  Office or any  similar  office or agency in any other  country or any
political  subdivision  thereof,  unless it promptly informs the Agent and, upon
request of the Agent, executes and delivers any and all agreements, instruments,
documents  and papers as the Agent may request to evidence the Agent's  security
interest in such Patent or Trademark and the goodwill and general intangibles of
the  Debtor  relating  thereto or  represented  thereby,  and the Debtor  hereby
constitutes the Agent its attorney-in-fact to execute and file all such writings
for the foregoing purposes, all such acts of such attorney being hereby ratified
and confirmed.

(f) Pursuit of Applications  and Maintenance of  Registrations.  The Debtor will
take all necessary  steps,  including,  without  limitation,  in any  proceeding
before the United States Patent and  Trademark  Office or any similar  office or
agency in any other country or any political  subdivision  thereof,  to maintain
and pursue each  application  (and to obtain the relevant  registration)  and to
maintain each  registration  of the Patents and  Trademarks,  including  without
limitation, filing of applications for renewal, affidavits of use and affidavits
of incontestability;  provided,  however, that no such Patent or Trademark shall
be required to be  maintained  or pursued to the extent such Patent or Trademark
is  determined  by the  Debtor,  after  consultation  with the  Agent,  to be of
negligible economic value to the Debtor.

(g) Notice of  Infringement.  If any of the Patent and  Trademark  Collateral is
infringed,  misappropriated  or  diluted  by a third  party,  the  Debtor  shall
promptly  notify the Agent after it learns thereof and shall,  unless the Debtor
shall reasonably determine,  after consultation with the Agent, that such Patent
and Trademark Collateral is of negligible economic value to the Debtor, promptly
sue for infringement, misappropriation of dilution, seek injunctive relief where
appropriate   and  recover   any  and  all   damages   for  such   infringement,
misappropriation  or  dilution,  or take such other  action as the Debtor  shall

Contract in respect of which the Debtor is required to execute an  Assignment of
Federal  Contract in accordance with Section 4.21 hereof,  the Debtor shall give
prompt written  notice to the Agent if the U.S.  Government  shall  terminate or
threaten to  terminate  (whether  for  convenience  or default) any such Federal
Contract  with the Debtor  having a value  (including  unexercised  options)  of
$100,000 or more. In addition,  the Debtor shall give prompt  written  notice to
the Agent if the U.S.  Government  shall  terminate or threaten to terminate any
contract between the U.S.  Government and any other prime contractor under which
the  Debtor  is a  subcontractor  if the  value of such  subcontract  (including
unexercised  options) is $100,000 or more. Section 4.21. Federal Contracts.  The
Debtor shall  provide to the Agent,  as soon as reasonably  practicable  but not
later than  forty-five  (45) days  following the end of each Fiscal  Quarter,  a
report identifying each Federal Contract to which it is a party, having attached
thereto a copy of the first two pages of such Federal Contract and any amendment
thereto,  to the extent not previously  provided to the Agent. At the request of
the Agent (unless an Event of Default shall have occurred and be continuing,  in
which case no such request  shall be  required),  the Debtor  shall  execute and
deliver to the Agent an Assignment of Federal  Contract,  in  substantially  the
form of Exhibit A hereto (the "Assignment of Federal Contract"), and execute any
other  instruments  or take any other steps  required by the Agent in order that
all moneys due or to become due under such Federal  Contracts  shall be assigned

each Federal Contract as contemplated by Appendix A to Exhibit A hereto.

Section 4.22.  Reimbursement  Obligation.  Should the Debtor fail to comply with
the provisions of this Security Agreement, the Revolving Credit Agreement or any
other agreement relating to the Collateral such that the value of any Collateral
or the validity,  perfection,  rank or value of any security interest granted to
the  Agent  hereunder  or  thereunder  is  thereby   diminished  or  potentially
diminished or put at risk (as reasonably  determined by the Agent), the Agent on
behalf of the Debtor may, but shall not be required to,  effect such  compliance
on behalf of the Debtor,  and the Debtor shall  reimburse the Agent for the cost
thereof on demand,  and interest shall accrue on such  reimbursement  obligation
from the date the relevant  costs are incurred  until  reimbursement  thereof in
full at the Default Rate.

ARTICLE V.

                                      REMEDIES; RIGHTS UPON DEFAULT

Section 5.01. UCC Rights.  In the event that any portion of the  Obligations has
been declared or becomes due and payable in accordance with the Revolving Credit
Agreement or other Credit  Documents and such  Obligations have not been paid in
full,  the Agent may in addition to all other rights and remedies  granted to it
in this Security  Agreement and in any other  instrument or agreement  securing,
guarantying,  evidencing or relating to the Obligations, exercise (i) all rights
and  remedies of a secured  party under the UCC (whether or not in effect in the
jurisdiction  where  such  rights  are  exercised)  and  (ii) all  other  rights
available to the Agent at law or in equity.

     Section 5.02.  Payments on Collateral.  Without  limiting the rights of the
     Agent under any other provision of this Security Agreement,  if an Event of
     Default shall occur and be continuing:

(i) all payments  received by the Debtor under or in connection  with any of the
Collateral  shall  be held by the  Debtor  in  trust  for the  Agent,  shall  be
segregated  from other funds of the Debtor and shall  forthwith  upon receipt by
the Debtor be turned  over to the  Agent,  in the same form as  received  by the
Debtor  (duly  indorsed  by the  Debtor  to the  Agent,  if  required  to permit
collection thereof by the Agent); and

(ii) all such  payments  received  by the  Agent  (whether  from the  Debtor  or
otherwise)  may, in the sole  discretion  of the Agent,  be held by the Agent as
collateral  security for, and/or then or at any time thereafter applied in whole
or in part by the Agent to the payment of, the expenses and the  Obligations  as
set forth in Section 5.11 hereof.

Section 5.03.  Possession of Collateral.  In  furtherance of the foregoing,  the
Debtor  expressly  agrees  that,  if an  Event of  Default  shall  occur  and be
continuing, the Agent may (i) by judicial powers, or without judicial process if
it can be done without breach of the peace, enter any premises where any of such
Collateral is or may be located and,  without  charge or liability to the Agent,
seize and remove such  Collateral from such premises and (ii) have access to and
use of the Debtor's books and records relating to such Collateral.

Section 5.04.     Sale of Collateral; Notice.

(a) Sale of Collateral.  The Debtor expressly agrees that if an Event of Default
shall occur and be continuing, the Agent, without demand of performance or other
demand or notice of any kind (except the notice  specified below of the time and
place of any public or private  sale) to or upon the Debtor or any other  Person
(all of which  demands  and/or  notices are hereby  waived by the  Debtor),  may
forthwith (i) apply the cash, if any, then held by it as collateral as specified
in Section  5.11 hereof and (ii) if there shall be no cash or such cash shall be
insufficient to pay the Obligations in full, collect,  receive,  appropriate and
realize upon the Collateral,  and/or sell, assign,  give an option or options to
purchase or otherwise  dispose of and deliver the  Collateral (or contract to do
so) or any part thereof in one or more parcels (which need not be in round lots)
at public or  private  sale,  at any  office of the Agent or  elsewhere  in such
manner as is  commercially  reasonable and, as the Agent may deem best, for cash
or on credit or for future delivery  without  assumption of any credit risk. The
Agent shall have the right upon any such public sale,  and, if the Collateral is
of a type customarily  sold in a recognized  market or is of a type which is the
subject of widely distributed  standard price quotations,  upon any such private
sale or sales,  to purchase the whole or any part of the Collateral so sold, and
thereafter to hold the same,  absolutely and free from any right or claim of any
kind. To the extent  permitted by applicable  law, the Debtor waives all claims,
damages  and  demands  against  the  Agent  arising  out  of  the   foreclosure,
repossession, retention or sale of the Collateral.

(b) Notice of Sale. Unless the Collateral threatens to decline speedily in value
or is of a type  customarily sold on a recognized  market,  the Agent shall give
the Debtor  ten (10)  days'  written  notice of its  intention  to make any such
public or private sale or sale at a broker's board or on a securities  exchange.
Such  notice  shall (i) in the case of a public  sale,  state the time and place
fixed  for  such  sale,  (ii) in the  case of sale at a  broker's  board or on a
securities  exchange,  state the board or  exchange  at which such sale is to be
made and the day on which the  Collateral,  or the portion  thereof  being sold,
will first be offered  for sale and (iii) in the case of a private  sale,  state
the day after which such sale may be consummated.  The Agent shall not obligated
to make any such sale  pursuant  to any such  notice.  The Agent may adjourn any
public or private  sale or cause the same to be  adjourned  from time to time by
announcement at the time and place fixed for the sale, and such sale may be made
at any time or place to which the same may be so  adjourned.  In the case of any
sale of all or any part of the Collateral on credit or for future delivery,  the
Collateral  so sold may be retained by the Agent until the selling price is paid
by the purchaser thereof, but the Agent shall not incur any liability in case of
the failure of such purchase to take up and pay for the  Collateral so sold and,
in the case of such failure, such Collateral may again be sold upon like notice.

(c) Special  Provisions  Relating to Sales of Securities.  The Debtor recognizes
that  the  Agent  may be  unable  to  effect  a  public  sale  of any or all the
Collateral  constituting a "security" (as such term is defined in the Securities
Act) by reason of  certain  prohibitions  contained  in the  Securities  Act and
applicable state securities laws or otherwise, and may be compelled to resort to
one or more private sales thereof to a restricted  group of purchasers that will
be obliged to agree,  among other things,  to acquire such  securities for their
own account for  investment  and not with a view to the  distribution  or resale
thereof.  The Debtor  acknowledges  and agrees  that any such  private  sale may
result in prices and other terms less  favorable than if such sale were a public
sale and, notwithstanding such circumstances,  agrees that any such private sale
shall be deemed to have been made in a commercially reasonable manner. The Agent
shall be under no obligation to delay a sale of any of Collateral constituting a
security  for the  period of time  necessary  to permit  the  issuer  thereof to
register  such  securities  for public sale under the  Securities  Act, or under
applicable state securities laws, even if such issuer would agree to do so.

Section 5.05.  Rights of Purchasers.  Upon any sale of the  Collateral  (whether
public or  private),  the Agent  shall  have the right to  deliver,  assign  and
transfer  to the  purchaser  thereof  the  Collateral  so sold.  Each  purchaser
(including  the  Agent)  at any such  sale  shall  hold the  Collateral  so sold
absolutely,  free from any claim or right of whatever kind, including any equity
or right of redemption of the Debtor who, to the extent permitted by law, hereby
specifically waives all rights of redemption, including, without limitation, any
right to redeem the Collateral  under Section 9-506 of the UCC, and any right to
a judicial or other stay or approval  which it has or may have under any law now
existing or hereafter adopted.

Section 5.06.     Additional Rights of the Agent.

(a) Right to Maintain Proceedings.  The Agent (i) shall have the right and power
to institute and maintain such suits and proceedings as it may deem  appropriate
to protect and enforce the rights  vested in it by this  Security  Agreement and
(ii) may proceed by suit or suits at law or in equity to enforce such rights and
to foreclose  upon the  Collateral and to sell all or, from time to time, any of
the   Collateral   under  the  judgment  or  decree  of  a  court  of  competent
jurisdiction.

(b)  Appointment  of  Receiver.  The Agent  shall,  to the extent  permitted  by
applicable law,  without notice to the Debtor to any party claiming  through the
Debtor,  without regard to the solvency or insolvency at such time of any Person
then liable for the  payment of any of the  Obligations,  without  regard to the
then value of the Collateral and without requiring any bond from any complainant
in such  proceedings,  be entitled as a matter of right to the  appointment of a
receiver  or  receivers  (who may be the  Agent) of the  Collateral  or any part
thereof,  pending  such  proceedings,  with such powers as the court making such
appointment  shall  confer,  and to the  entry  of an order  directing  that the
profits, revenues and other income of the property constituting the whole or any
part of the Collateral be segregated,  sequestered and impounded for the benefit
of the Agent,  and the Debtor  irrevocably  consents to the  appointment of such
receiver or receivers and to the entry of such order.

(c) No Duty to  Exercise  Rights.  In no event  shall the Agent have any duty to
exercise any rights or take any steps to preserve the rights of the Agent in the
Collateral,  nor shall the Agent be liable to the Debtor or any other Person for
any loss caused by the Agent's failure to meet any obligation imposed by Section
9-207 of the UCC or any successor provision. Without limiting the foregoing, the
Agent  shall be deemed to have  exercised  reasonable  care in the  custody  and
preservation  of the  Collateral in its possession if the Collateral is accorded
treatment  substantially equal to that which the Agent accords its own property,
it being understood that the Agent shall not have any duty or responsibility for
(i) ascertaining or taking action with respect to calls, conversions, exchanges,
maturities,  tenders or other matters relative to any Collateral, whether or not
the Agent has or is deemed to have knowledge of such matters, or (ii) taking any
necessary  steps to preserve  rights  against any  parties  with  respect to any
Collateral.

Section 5.07.     Remedies Not Exclusive, etc.

(d) Remedies Not Exclusive. No remedy conferred upon or reserved to the Agent in
this  Security  Agreement  is intended to be  exclusive  of any other  remedy or
remedies,  but every such remedy shall be cumulative and shall be in addition to
every other  remedy  conferred  herein or now or  hereafter  existing at law, in
equity or by statute.

(e)  Restoration  of Rights.  If the Agent shall have  proceeded  to enforce any
right,  remedy or power under this Security Agreement and the proceeding for the
enforcement  thereof shall have been discontinued or abandoned for any reason or
shall have been  determined  adversely  to the  Agent,  the Debtor and the Agent
shall,   subject  to  any  determination  in  such  proceeding,   severally  and
respectively  be  restored  to their  former  positions  and  rights  under this
Security Agreement,  and thereafter all rights, remedies and powers of the Agent
shall continue as though no such proceedings had been taken.

(f)  Enforcement.  All rights of action  under this  Security  Agreement  may be
enforced by the Agent without the  possession of any  instrument  evidencing any
Obligation or the production  thereof at any trial or other proceeding  relative
thereto, and any suit or proceeding  instituted by the Agent shall be brought in
its name and any judgment shall be held as part of the Collateral.

Section 5.08.     Waiver and Estoppel.

(a) No Actions to Impede Sale of Collateral. The Debtor agrees, to the extent it
may lawfully do so, that it will not at any time in any manner  whatsoever claim
or take the benefit or advantage of any appraisal,  valuation,  stay, extension,
moratorium,  turnover or redemption  law, or any law permitting it to direct the
order in which the  Collateral  shall be sold,  now or at any time  hereafter in
force  which  may  delay,   prevent  or  otherwise  affect  the  performance  or
enforcement  of this  Security  Agreement,  and  hereby  waives  all  benefit or
advantage of all such laws. The Debtor covenants that it will not hinder,  delay
or impede  the  execution  of any power  granted  to the Agent in this  Security
Agreement, any Assignment of Federal Contract or any other Credit Document.

(b) Collateral Sold As An Entirety. The Debtor, to the extent it may lawfully do
so, on behalf of itself and all who claim through or under it, including without
limitation any and all  subsequent  creditors,  vendees,  assignees and lienors,
waives  and  releases  all  rights to demand or to have any  marshalling  of the
Collateral upon any sale, whether made under any power of sale granted herein or
pursuant to judicial  proceedings or under any foreclosure or any enforcement of
this Security Agreement,  and consents and agrees that all of the Collateral may
at any such sale be offered and sold as an entirety.

(c) Waiver of  Notices.  The Debtor  waives,  to the  extent  permitted  by law,
presentment,  demand,  protest  and any notice of any kind  (except  the notices
expressly required hereunder) in connection with this Security Agreement and any
action taken by the Agent with respect to the Collateral.

Section 5.09.     Power of Attorney; Powers Coupled With An Interest.

(a) Power of Attorney.  Without limiting any other right granted hereunder,  the
Debtor hereby irrevocably constitutes and appoints the Agent, with full power of
substitution,  as its true and  lawful  attorney-in-fact  with full  irrevocable
power and  authority in the place and stead of the Debtor and in the name of the
Debtor  or in its  own  name,  from  time  to  time  in the  Agent's  reasonable
discretion,  for the  purpose  of  carrying  out  the  terms  of  this  Security
Agreement,  to take any and all  appropriate  action and to execute  any and all
documents and instruments  which may be necessary or desirable to accomplish the
purpose of this Security  Agreement and,  without limiting the generality of the
foregoing,  hereby gives the Agent the power and right, on behalf of the Debtor,
without notice to or assent by the Debtor, to do the following:

     (i)  to  pay  or  discharge  taxes,  liens,  security  interests  or  other
     encumbrances levied or placed on or threatened against the Collateral;

(ii) to effect  any  repairs  or any  insurance  called for by the terms of this
Security  Agreement or any other Credit Document,  and to pay all or any part of
the premiums therefor and the costs thereof;

(iii) upon the occurrence and  continuance of any Event of Default and otherwise
to the  extent  provided  in this  Security  Agreement,  (A) to direct any party
liable for any payment  under any of the  Collateral  to make payment of any and
all moneys due and to come due thereunder  directly to the Agent or as the Agent
shall direct,  (B) to receive  payment of and receipt for, and to demand and sue
for, any and all moneys,  claims and other  amounts due and to become due at any
time in respect of or arising out of the Collateral, (C) to sign and indorse and
receive,  take, assign and deliver, any checks,  notes,  drafts,  negotiable and
non-negotiable  instruments,  any invoices,  freight or express bills,  bills of
lading,  storage or warehouse  receipts,  drafts against  debtors,  assignments,
verifications  and  notices in  connection  with  accounts  and other  documents
relating to the  Collateral,  (D) to  commence,  settle,  compromise,  compound,
prosecute,  defend or adjust any claim,  suit, action or proceeding with respect
to, or in connection  with, the  Collateral,  (E) to sell,  transfer,  assign or
otherwise  deal in or with the  Collateral  or any part  thereof,  as fully  and
effectively  as if the Agent were the absolute  owner  thereof and (F) to do, at
its option,  but at the expense of the Debtor, at any time or from time to time,
all acts and things  which the Agent deems  necessary  to  protect,  preserve or
realize upon the Collateral and the Agent's security interest therein,  in order
to effect the intent of this Security Agreement, all as fully and effectively as
the Debtor might do.

(b) Powers Coupled With an Interest.  All authorizations and agencies granted or
provided  herein with respect to the  Collateral,  including the powers  granted
under clause (a) of this Section 5.9, are irrevocable and powers coupled with an
interest.

Section 5.10. Certain Provisions Relating to Securities.  Solely with respect to
any Collateral  constituting a "security" (as defined in the Securities Act), if
an Event of Default shall have occurred and be continuing,  all such  securities
(as defined in the Securities Act)  constituting a part of the Collateral shall,
at the  request  of the  Agent,  be  registered  in the name of the Agent or its
nominee,  and the Agent or its nominee may  thereafter  exercise (i) all voting,
corporate and other rights,  powers and privileges pertaining to such Collateral
at any meeting of shareholders of the issuer thereof or otherwise,  and (ii) any
and all  rights of  conversion,  exchange,  subscription  and any other  rights,
privileges or options  pertaining to such  Collateral as if it were the absolute
owner  thereof  (including,  without  limitation,  the right to  exchange at its
discretion  any  and  all  such  Collateral  upon  the  merger,   consolidation,
reorganization, recapitalization or other fundamental change in the structure of
any such  issuer,  or upon the exercise by the Debtor or the Agent of any right,
privilege or option pertaining to such Collateral,  and in connection therewith,
the right to deposit and deliver any and all such Collateral with any committee,
depositary, transfer agent, registrar or other designated agency upon such terms
and conditions as it may determine), all without liability except to account for
property  actually  received  by it and except as  provided  in  Section  5.6(c)
hereof,  but the Agent  shall  have no duty to the Debtor to  exercise  any such
right, privilege or option and shall not be responsible for any failure to do so
or delay in so doing.

     Section 5.11.  Application of Monies. The proceeds of any sale of, or other
     realization upon, all or any part of the Collateral shall be applied by the
     Agent in the following order of priority:

                  first,  to  payment  of the  expenses  of such  sale or  other
realization,  including reasonable  compensation to the Agent and its agents and
counsel,  and all  expenses,  liabilities  and advances  incurred or made by the
Agent, its agents and counsel in connection  therewith or in connection with the
care, safekeeping or otherwise of any or all of the Collateral;

     second,  to  payment  of the  Obligations,  in such  order as the Agent may
     elect; and

                  third, any surplus then remaining shall be paid to the Debtor,
or its  successors  or assigns,  or to  whomsoever  may be lawfully  entitled to
receive the same (including  pursuant to Section 9-504(1)(C) of the UCC) or as a
court of competent jurisdiction may direct.

ARTICLE VI.

                                              MISCELLANEOUS

Section 6.01. Notices. All notices, requests and other communications to a party
hereunder  shall be in writing  and shall be given to such party at its  address
set forth on the  signature  page hereof or such other address as such party may
hereafter  specify for that  purpose by notice to the other.  Each such  notice,
request or other  communication shall be effective (i) in the case of telephonic
notice (to the extent  expressly  permitted  hereunder),  when made, (ii) in the
case of notice delivered by overnight  express  courier,  one Business Day after
the Business Day such notice was delivered to such courier, (iii) in the case of
notice  delivered by first class mail, three Business Days after being deposited
in the mail,  postage  prepaid,  return receipt  requested,  (iv) in the case of
notice by hand,  when  delivered,  or (v) in the case of notice by any customary
means of telecommunication, when sent provided confirmation of receipt or answer
back has been  received,  in each  case if  addressed  to any  party  hereto  as
provided  herein.  Rejection or refusal to accept,  or the  inability to deliver
because of a changed address of which no notice was given,  shall not affect the
validity of notice given in accordance with this section.

Section 6.02.  No Waiver;  Cumulative  Remedies.  The Agent shall not by any act
(except by a written  instrument  pursuant  to Section  6.3 hereof) be deemed to
have waived any right or remedy hereunder. No failure to exercise, nor any delay
in exercising,  on the part of the Agent any right, power or privilege hereunder
shall operate as a waiver thereof.  No single or partial  exercise of any right,
power or  privilege  hereunder  shall  preclude  any other or  further  exercise
thereof or the exercise of any other right, power or privilege.  A waiver by the
Agent  of any  right  or  remedy  hereunder  on any one  occasion  shall  not be
construed as a bar to any right or remedy which the Agent would  otherwise  have
on any future occasion.  The rights and remedies herein provided are cumulative,
may be  exercised  singly or  concurrently  and are not  exclusive  of any other
rights or remedies provided by law.

Section 6.03.  Amendments  and Waivers.  None of the terms or provisions of this
Security Agreement may be amended,  supplemented or otherwise modified except by
a written  instrument  executed by the Debtor and the Agent;  provided  that any
provision of this  Security  Agreement may be waived by the Agent in a letter or
agreement  executed by the Agent or by telex or facsimile  transmission from the
Agent.

Section 6.04.  Successors and Assigns. The provisions of this Security Agreement
shall be binding  upon and inure to the benefit of the parties  hereto and their
respective  successors and assigns;  provided,  however, that the Debtor may not
assign or transfer any of its rights or obligations  hereunder without the prior
written consent of the Agent.
     Section 6.05.  Governing Law. THIS SECURITY  AGREEMENT SHALL BE GOVERNED BY
     AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE  COMMONWEALTH OF VIRGINIA,
     OTHER THAN ITS LAWS RESPECTING  CHOICE OF LAW OTHER THAN THOSE CONTAINED IN
     THE UCC.

Section 6.06.     Limitation by Law; Severability.

(a) All rights,  remedies and powers provided in this Security  Agreement may be
exercised  only to the extent  that the  exercise  thereof  does not violate any
applicable  provision of law, and all the provisions of this Security  Agreement
are intended to be subject to all applicable  mandatory  provisions of law which
may be controlling  and to be limited to the extent  necessary so that they will
not render this Security Agreement  invalid,  unenforceable in whole or in part,
or not entitled to be recorded,  registered or filed upon the  provisions of any
applicable law.

(b) If any provision hereof is invalid and  unenforceable  in any  jurisdiction,
then, to the fullest extent  permitted by law, (i) the other  provisions  hereof
shall  remain  in full  force  and  effect  in such  jurisdiction  and  shall be
liberally  construed in favor of the Agent in order to carry out the  intentions
of the parties  hereto as nearly as may be possible and (ii) the  invalidity  or
unenforceability  of any provision hereof in any  jurisdiction  shall not affect
the validity or enforceability of such provision in any other jurisdiction.

Section  6.07.  Counterparts.  This  Security  Agreement  may be executed in any
number of counterparts and by different parties hereto on separate counterparts,
each complete set of which, when so executed and delivered by all parties, shall
be an original,  but all such counterparts shall together constitute but one and
the same instrument.

Section 6.08. Expenses of the Agent. The Debtor shall pay to the Agent from time
to time upon demand,  all of the costs and expenses incurred by the Agent or any
Lender (including,  without limitation, the reasonable fees and disbursements of
counsel  and any  amounts  payable  by the  Agent or any  Lender to any of their
respective   agents)  (i)  arising  in  connection   with  the   administration,
modification, amendment, waiver or termination of this Security Agreement or any
document or agreement  contemplated hereby or any consent or waiver hereunder or
thereunder  or (ii)  incurred  in  connection  with the  administration  of this
Security  Agreement,  or any document or agreement  contemplated  hereby,  or in
connection  with the  administration,  sale or other  disposition  of Collateral
hereunder  or  under  any  document  or  agreement  contemplated  hereby  or the
preservation,  protection or defense of the rights of the Agent or any Lender in
and to the Collateral.

Section  6.09.  Indemnification.   The  Debtor  shall  at  all  times  hereafter
indemnify, hold harmless and, on demand, reimburse the Agent and the Lenders and
their  respective  subsidiaries,   affiliates,  successors,  assigns,  officers,
directors,   employees  and  agents,  and  their  respective  heirs,  executors,
administrators, successors and assigns (all of the foregoing parties, including,
but not limited to, the Agent, being hereinafter collectively referred to as the
"Indemnities" and individually as an "Indemnitee") from, against and for any and
all liabilities,  obligations,  claims, damages, actions,  penalties,  causes of
action, losses, judgments, suits, costs, expenses and disbursements,  including,
without  limitation,  attorney's  fees  (any  and  all  of the  foregoing  being
hereinafter  collectively referred to as the "Liabilities" and individually as a
"Liability")  which  the  Indemnitees,  or  any  of  them,  might  be or  become
subjected, by reason of, or arising out of the preparation, execution, delivery,
modification,  administration  or enforcement  of, or performance of the Agent's
rights  under,  this  Security  Agreement or any other  document,  instrument or
agreement  contemplated  hereby or executed in  connection  herewith;  provided,
however, that the Debtor shall not be liable to any Indemnitee for any Liability
caused solely by the gross negligence or willful  misconduct of such Indemnitee.
In no event shall any  Indemnitee,  as a condition to enforcing its rights under
this Section 6.9 or  otherwise,  be obligated to make a claim  against any other
Person (including,  without  limitation,  the Agent) to enforce its rights under
this Section 6.9.

Section 6.10.  Termination;  Survival.  This Security  Agreement shall terminate
when the security interests granted hereunder have terminated and the Collateral
has been  released as  provided  in Section  2.6;  provided,  however,  that the
obligations  of the Debtor under Section 4.22 and the provisions of this Article
6 shall survive any such termination.

Section  6.11.  Judicial  Proceedings;   Waiver  of  Jury  Trial.  Any  judicial
proceeding  brought  against  the Debtor  with  respect to any Credit  Agreement
Related  Claim hereby may be brought in any court of competent  jurisdiction  in
the  Commonwealth  of Virginia,  County of Fairfax,  or any Federal court in the
Eastern  District of Virginia,  and, by execution  and delivery of this Security
Agreement,   the  Debtor  (a)  accepts,   generally  and  unconditionally,   the
nonexclusive  jurisdiction  of such courts and any related  appellate  court and
irrevocably  agrees to be bound by any judgment  rendered  thereby in connection
with any Credit Agreement Related Claim and (b) irrevocably waives any objection
it may now or hereafter have as to the venue of any such  proceeding  brought in
such a court or that such a court is an  inconvenient  forum.  The Debtor hereby
waives personal  service of process and consents that service of process upon it
may be made by certified or registered mail,  return receipt  requested,  at its
address specified or determined in accordance with the provisions of Section 6.1
hereof,  and service so made shall be deemed completed on the earlier of (x) the
receipt  thereof and (y) if sent by registered or certified mail (return receipt
requested),  the fifth (5th) Business Day after such service is deposited in the
mail. Nothing herein shall affect the right of the Agent to serve process in any
other  manner  permitted  by law or shall  limit the right of the Agent to bring
proceedings  against  the  Debtor in the courts of any other  jurisdiction.  Any
judicial proceeding by the Debtor against the Agent relating to or involving any
Credit  Agreement  Related Claim hereby shall be brought only in a court located
in the Commonwealth of Virginia,  County of Fairfax, or the Federal court in the
Eastern  District of Virginia.  THE DEBTOR AND THE AGENT HEREBY  UNCONDITIONALLY
WAIVE  TRIAL  BY JURY IN ANY  JUDICIAL  PROCEEDING  TO WHICH  THEY  ARE  PARTIES
INVOLVING ANY CREDIT AGREEMENT RELATED CLAIM.

Section  6.12.  Integration.  This  Security  Agreement  and  the  other  Credit
Documents  constitute  the entire  agreement  of the  Agent,  the  Lenders,  the
Borrower and the other Credit  Parties with respect to the subject matter hereof
and  thereof,  and  there  are no  promises,  undertakings,  representations  or
warranties by the Agent or any Lender  relative to the subject  matter hereof or
thereof not  expressly  set forth or  referred to herein or in the other  Credit
Documents.

Section 6.13.  Authority of Agent. The Debtor  acknowledges  that the rights and
responsibilities  of the Agent under this Security Agreement with respect to any
action  taken by the Agent or the exercise or  non-exercise  by the Agent of any
option,  voting right,  request,  judgment or other right or remedy provided for
herein or resulting or arising out of this Security  Agreement shall, as between
the Agent and the Lenders,  be governed by the Revolving Credit Agreement and by
such other  agreements with respect thereto as may exist from time to time among
them, but, as between the Agent and the Debtor,  the Agent shall be conclusively
presumed to be acting as agent for the Lenders with full and valid  authority so
to act or refrain from acting, and the Debtor shall not be under any obligation,
or entitlement, to make any inquiry respecting such authority.

Section 6.14. Headings,  Bold Type and Table of Contents.  The section headings,
subsection headings,  and bold type used herein and the Table of Contents hereto

good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the Assignor covenants and agrees as follows:

         1. Incorporation By Reference. The provisions of the Security Agreement
are  incorporated  herein by  reference,  and the terms  defined in the Security
Agreement are used herein with the same meanings.

         2.  Representations.  The Assignor represents and warrants to the Agent
that (a) the Contract is legal,  valid and binding on the  Assignor  and, to its
knowledge,  the other parties thereto,  is in full force and effect,  and is not
evidenced  by any  chattel  paper or  instrument,  (b) upon due  filing  of this
Agreement,  together  with a Notice of Assignment  substantially  in the form of
Appendix A hereto with the authorized representative, the execution and delivery
of this Agreement does not violate and is not in conflict with the provisions of
the  Contract,  (c) there has been no default on the part of the Assignor or any

covering  the  Contract  is on  file  in  any  public  office  except  financing
statements in favor of the Agent,  (f) no set-off or  counterclaim to any moneys

         3. Collateral. As security and collateral for the payment of all of the
Obligations  (defined in the Security  Agreement)  and for  performance  of, and
compliance  with,  by the  Assignor,  all of the terms,  covenants,  conditions,
stipulations,  and  agreements  contained in this  Agreement and in the Security
Agreement,  the Assignor hereby assigns to the Agent,  and grants to the Agent a
lien on and  security  interest  in,  all  moneys  and claims for moneys now and
hereafter  due and to  become  due to the  Assignor  under or by  reason  of the
Contract,  together  with all  cash and  non-cash  proceeds  thereof;  provided,
however,  that nothing  contained  herein shall impose upon the Agent any of the
obligations or liabilities of the Assignor under the Contract.

         4. Covenants. Until payment and performance in full of the Obligations,
the Assignor covenants as follows:

instruments demanding payment under the Contract the direction that such payment
is to be made to the Agent in accordance with Section 5 of this Agreement.

the  preparation,  execution,  recording,  and  filing of any such  document  or

constitute  and become a part of the  Obligations.  A carbon,  photographic,  or
other  reproduction  of  a  security  agreement  or  a  financing  statement  is
sufficient as a financing statement.

(e) The Assignor shall fully,  promptly,  and faithfully comply with and perform
its  obligations  and duties  under the  Contract in  accordance  with the terms
thereof and will make no changes or  amendments  to the Contract or terminate or

rendered by the Assignor under or in connection with the Contract.

(g) The  Assignor  will at all times  keep  accurate  and  complete  records  of
performance  by the Assignor  under the  Contract,  and the Agent and its agents
shall have the right,  during normal business hours and upon reasonable  advance
notice,  to call at the place or places of business of the Assignor at intervals

audit,  check,  and make extracts  from the books,  records,  journals,  orders,
receipts,  correspondence,  and other data  relating  to the  Contract or to any
other transactions between the parties hereto related to the Contract.

                                            SECURITY INTERESTS

Section  2.01.  Grant of  Security  Interests.  To secure  the due and  punctual
payment of all Obligations,  howsoever  created,  arising or evidenced,  whether
direct or indirect,  absolute or contingent, now or hereafter existing or due or
to become  due,  whether at  maturity  or upon  acceleration  or  otherwise,  in
accordance with the terms thereof and to secure the due and punctual performance
of all of the  Obligations  and in order to induce the Agent and the  Lenders to
enter into the Revolving  Credit Agreement and the other Credit  Documents,  the
Debtor hereby pledges,  assigns,  delivers,  conveys and transfers to the Agent,
for the ratable benefit of the Lenders, and grants to the Agent, for the ratable
benefit of the Lenders, a first priority and continuing security interest in and
lien on, all of the  Debtor's  right,  title and  interest  in, to and under the
following, whether now existing or hereafter acquired (the "Collateral"):

(i)      all Receivables;

(ii)     all Other Intangibles;

(iii)    all Equipment;

(iv)     all Inventory;

(v) to the  extent  not  included  in the  foregoing,  all  securities  (whether
certificated or uncertificated)  and all financial assets,  whether now existing
or hereafter arising, including, without limitation, all capital stock issued by
any Person and held by Debtor,  and all  partnership  interests,  whether in the
nature of a joint venture,  limited liability company member's interest,  master
limited partnership, teaming arrangement or otherwise;

(vi) to the extent not included in the foregoing,  all other personal  property,
whether  tangible or intangible,  and wherever located whether within or outside
of the United  States,  including,  but not  limited  to,  the  balance of every
deposit  account now or hereafter  existing of the Debtor with any bank or other
financial  institution and all monies of the Debtor and all rights to payment of
money of the Debtor;

(vii) to the extent not  included  in the  foregoing,  all  books,  ledgers  and
records and all computer  programs,  tapes,  discs, punch cards, data processing
software,  transaction  files,  master  files and  related  property  and rights
(including computer and peripheral equipment) necessary or helpful in enforcing,
identifying or establishing any item of Collateral; and

(viii) to the extent not otherwise included, all Proceeds and products of any or
all of the foregoing, whether existing on the date hereof or arising hereafter;

provided,  however,  notwithstanding  anything to the contrary contained herein,
the  Debtor is not  assigning,  pledging  or  otherwise  encumbering  under this
Security Agreement its interests in any Federal Contract to which it is a party,
or in accounts or receivables due to Debtor under such Federal Contract,  to the
extent,  but only to the extent,  such assignment,  pledge or other  encumbrance
would  breach or violate or would cause Debtor to breach or violate such Federal
Contract or statutes or regulations applicable thereto, it being understood that
this proviso does not apply to, or in any way limit, Debtor's assignment, pledge
or encumbrance of Proceeds of all Federal Contracts to which it is a party.

Section  2.02.  Continuing  Liability  of the  Debtor.  Anything  herein  to the
contrary notwithstanding,  the Debtor shall remain liable to observe and perform
all the  terms and  conditions  to be  observed  and  performed  by it under any
contract,   agreement,   warranty  or  other  obligation  with  respect  to  the
Collateral;  and  shall do  nothing  to impair  the  security  interests  herein
granted.  The Agent shall not have any  obligation  or liability  under any such
contract,  agreement, warranty or obligation by reason of or arising out of this
Security  Agreement  or the receipt by the Agent of any payment  relating to any
Collateral,  nor shall the Agent be  required  to perform or fulfill  any of the
obligations of the Debtor with respect to the Collateral, to make any inquiry as
to the nature or sufficiency of any payment received by it or the sufficiency of
the  performance  of any party's  obligations  with  respect to any  Collateral.
Furthermore,  the  Agent  shall not be  required  to file any claim or demand to
collect any amount due or to enforce the performance of any party's  obligations
with respect to, the Collateral.

Section 2.03.     Sales and Collections.

(a) Sales of  Inventory  in the  Ordinary  Course  of  Business.  The  Debtor is
authorized (i) to sell in the ordinary course of its business for fair value and
on an  arm's-length  basis  any of its  Inventory  normally  held by it for such
purpose and (ii) to use and consume, in the ordinary course of its business, any
raw materials,  supplies and materials normally held by it for such purpose. The
Agent may, upon the occurrence of any Event of Default, without cause or notice,
curtail or terminate such authority at any time.

(b) Collection of Receivables. The Debtor is authorized to collect amounts owing
to it with respect to the Collateral, except as otherwise provided in connection
with the Assignment of Federal Contract, if any as provided herein. However, the
Agent may, upon and during the continuance of an Event of Default or a Potential
Event of Default, notify Account Debtors obligated to make payments under any or
all Receivables or Other  Intangibles that the Agent has a security  interest in
such Collateral and that payments shall be made directly to the Agent.  Upon the
request of the Agent upon and during the continuance of an Event of Default or a
Potential  Event of Default,  as the case may be, the Debtor will so notify such
Account  Debtors  and  will  execute  such  contract  assignments,   notices  of
assignment or other  documents as may be required by such Account  Debtors.  The
Debtor will use all  reasonable  efforts to cause each Account  Debtor to comply
with the foregoing  instruction.  In furtherance  of the  foregoing,  the Debtor
authorizes the Agent upon and during the continuance of an Event of Default or a
Potential  Event of Default (i) to ask for,  demand,  collect,  receive and give
acquittances  and  receipts  for any and all amounts due and to become due under
any Collateral and in the name of the Debtor or its own name or otherwise,  (ii)
to  take  possession  of,  endorse  and  collect  any  checks,   drafts,  notes,
acceptances  or other  instruments  for the  payment  of  monies  due  under any
Collateral  and (iii) to file any claim or take any other action in any court of
law or equity or  otherwise  which it may deem  appropriate  for the  purpose of
collecting  any  amounts  due under any  Collateral.  The  Agent  shall  have no
obligation  to obtain or record any  information  relating to the source of such
funds or the obligations in respect of which payments have been made.

Section 2.04.     Segregation of Proceeds.

(a) Cash Collateral  Account  Maintained by Agent. Upon an Event of Default or a
Potential  Event of  Default,  the Agent shall have the right at any time during
the  continuance  thereof to cause to be opened and  maintained at the office of
the Agent in McLean,  Virginia a  non-interest  bearing  bank account (the "Cash
Collateral  Account") which will contain only Proceeds.  Any "cash proceeds" (as
such term is defined  in  Section  9-306(1)  of the UCC)  received  by the Agent
directly from Account  Debtors  obligated to make payments under  Receivables or
Other Intangibles  pursuant to Section 2.3 hereof or from the Debtor pursuant to
clause (b) of this Section 2.4,  whether  consisting of checks,  notes,  drafts,
bills of exchange, money orders,  commercial paper or other Proceeds received on
account of any  Collateral,  shall be promptly  deposited in the Cash Collateral
Account, and until so deposited shall be held in trust for the Agent as property
of the  Agent  and shall not be  commingled  with any  funds of the  Debtor  not
constituting  Proceeds  of  Collateral.  The name in which  the Cash  Collateral
Account is carried shall clearly  indicate that the funds deposited  therein are
the  property  of the  Debtor,  subject to the  security  interest  of the Agent
hereunder. Such Proceeds, when deposited,  shall continue to be security for the
Obligations   and  shall  not  constitute   payment  thereof  until  applied  as
hereinafter  provided.  The Agent shall have sole  dominion and control over the
funds deposited in the Cash Collateral Account,  and such funds may be withdrawn
therefrom only by the Agent.

(b) Deposit of  Proceeds  by the Debtor.  Upon notice by the Agent to the Debtor
that the Cash  Collateral  Account has been  opened,  the Debtor shall cause all
cash  Proceeds  collected  by it to be  delivered  to the Agent  forthwith  upon
receipt,  in the original  form in which  received  (with such  endorsements  or
assignments as may be necessary to permit collection  thereof by the Agent), and
for such  purpose the Debtor  hereby  irrevocably  authorizes  and  empowers the
Agent,  its officers,  employees and  authorized  agents to endorse and sign the
name of the Debtor on all checks, drafts, money orders or other media of payment
so delivered,  and such endorsements or assignments shall, for all purposes,  be
deemed to have been made by the Debtor prior to any  endorsement  or  assignment
thereof by the Agent.  The Agent may use any  convenient or customary  means for
the purpose of collecting  such checks,  drafts,  money orders or other media of
payment.

Section 2.05.  Verification  of  Receivables.  The Agent shall have the right to
make test  verifications of Receivables in any reasonable manner and through any
medium that it considers  advisable,  and the Debtor  agrees to furnish all such
assistance and  information  as the Agent may  reasonable  require in connection
therewith.  The Debtor at its expense will cause its chief financial  officer to
furnish to the Agent at any reasonable  time and from time to time promptly upon
the Agent's reasonable request,  the following reports:  (i) a reconciliation of
all Receivables, (ii) an aging of all Receivables, (iii) trial balances and (iv)
a test verification of such Receivables as the Agent may request.

Section 2.06.     Release of Collateral.

(a) Security  Interest of Agent Ceases Upon Permitted  Dispositions.  The Debtor
may sell or realize upon or transfer or otherwise  dispose of Collateral only to
the extent permitted by Section 4.13, and the security interests of the Agent in
such  Collateral so sold,  realized upon or disposed of (but not in the Proceeds
arising from such sale, realization or disposition) shall cease immediately upon
such sale, realization or disposition, without any further action on the part of
the Agent.  The Agent,  if requested in writing by the Debtor but at the expense
of the Debtor,  is hereby  authorized  and  instructed to deliver to the Account
Debtor or the purchaser or other transferee of any such Collateral a certificate
stating  that the Agent no longer  has a  security  interest  therein,  and such
Account Debtor or such purchaser or other  transferee  shall be entitled to rely
conclusively on such certificate for any and all purposes.

(b) Filing of  Termination  Statements.  Upon the  payment in full of all of the
Obligations  and if  there  is no  commitment  by any  Lender  to  make  further
advances,  incur obligations or otherwise give value, the Agent will (as soon as
reasonably  practicable  after receipt of notice from the Debtor  requesting the
same but at the  expense  of the  Debtor)  deliver  to the  Debtor  (i) for each
jurisdiction  in  which a UCC  financing  statement  is on file to  perfect  the
security  interests  granted to the Agent  hereunder,  a  termination  statement
(appropriately  completed)  to the  effect  that the  Agent no  longer  claims a
security interest under such financing statement,  and (ii) such other documents
as  the  Debtor  shall  reasonably  request   evidencing   satisfaction  of  the
Obligations  and the  release  of the  security  interests  granted to the Agent
hereunder.

ARTICLE III.

                                      REPRESENTATIONS AND WARRANTIES

         The Debtor represents and warrants that:

Section 3.01. Title to Collateral.  Except for the security interests granted to
the Agent  pursuant to this  Security  Agreement  and as otherwise  permitted by
Section 6.2(a) of the Revolving Credit  Agreement,  the Debtor is the sole owner
of each item of the Collateral,  having good and marketable title thereto,  free
and clear of any and all Liens.

Section 3.02.     Validity, Perfection and Priority of Security Interests.

(a) By complying  with Section 4.1 hereof,  the Debtor will have created a valid
security  interest in favor of the Agent in all existing  Collateral  and in all
identifiable  Proceeds of such  Collateral,  which security  interest (except in
respect of  Collateral  not located at a facility  identified  on  Schedule  3.7
hereto  and motor  vehicles  for  which the  exclusive  manner of  perfecting  a
security interest therein is by noting such security interest in the certificate
of title in accordance with local law) would be prior to the claims of a trustee
in bankruptcy under Section 544(a) of the Bankruptcy Code. Continuing compliance
by the Debtor  with the  provisions  of Section  4.2 hereof will also (i) create
valid security interests in all Collateral acquired after the date hereof and in
all  identifiable  Proceeds  of such  Collateral  and (ii) cause  such  security
interests in all Collateral and in all Proceeds which are (A) identifiable  cash
Proceeds of  Collateral  covered by  financing  statements  required to be filed
hereunder,  (B)  identifiable  Proceeds  in  which a  security  interest  may be
perfected  by such  filing  under  the UCC and  (C)  any  Proceeds  in the  Cash
Collateral Account to be duly perfected under the UCC, in each case prior to the
claims of a trustee in bankruptcy  under the Bankruptcy  Code (except in respect
of Collateral not located at a facility identified on Schedule 3.5 hereto).

(b) The  security  interests  of the  Agent  in the  Collateral  located  at the
facilities identified on Schedule 3.5 hereto rank first in priority.  Other than
financing   statements  or  other  similar  documents  perfecting  the  security
interests  in favor of the  Agent,  no  financing  statements,  deeds of  trust,
mortgages or similar documents covering all or any part of the Collateral are on
file or of record in any  government  office in any  jurisdiction  in which such
filing or recording  would be  effective to perfect a security  interest in such
Collateral,  nor is any of the Collateral in the possession of any Person (other
than the Debtor) asserting any claim thereto or security interest therein.

Section 3.03.  Enforceability of Receivables and Other Intangibles.  To the best
knowledge of the Debtor,  each  Receivable  and Other  Intangible is a valid and
binding obligation of the related Account Debtor in respect thereof, enforceable
in accordance with its terms,  except as such  enforceability  may be limited by
applicable bankruptcy,  insolvency,  reorganization,  moratorium or similar laws
affecting  the  enforcement  of  creditors'  rights  generally  and  by  general
provisions of equity (regardless of whether such enforceability is considered in
a  proceeding  in equity or at law),  and  complies  with any  applicable  legal
requirements.

Section 3.04.  Place of Business.  Schedule 3.4  correctly  sets forth the chief
executive  office and principal  place of business of the Debtor and the offices
of the Debtor where records  concerning  Receivables  and Other  Intangibles are
kept.

Section 3.05.  Location of  Collateral.  Schedule 3.5  correctly  sets forth the
location of all Equipment and Inventory,  other than rolling stock, aircraft and
goods in transit.  Except as otherwise  specified in Schedule 3.5, all Inventory
and Equipment  has been located at the address  specified on Schedule 3.5 at all
times during the  four-month  period prior to the date hereof while owned by the
Debtor.  All Inventory has been and will be produced in compliance with the Fair
Labor Standards Act, 29 U.S.C.  ss.ss.  201-219,  except for such non-compliance
which could not reasonably be expected to have a material  adverse effect on the
Debtor. No Inventory is evidenced by a negotiable  document of title,  warehouse
receipt  or bill of  lading.  No  non-negotiable  document  of title,  warehouse
receipt or bill of lading has been  issued to any person  other than the Debtor,
and the Debtor has retained possession of all of such non-negotiable  documents,
warehouse receipts and bills of lading. No amount payable under or in connection
with  any  of  the  Collateral  is  evidenced  by  promissory   notes  or  other
instruments.

Section 3.06.  Trade Names.  Schedule 3.6 correctly sets forth any and all trade
names,  division  names,  assumed  names or other  names  under which the Debtor
currently  transacts  business or has transacted  business within the four-month
period prior to the date hereof.

     Section 3.07. Patents and Trademarks. Schedule 3.7 correctly sets forth all
     Patents,  Patent licenses,  Trademarks and Trademark  licenses now owned by
     the Debtor.


ARTICLE IV.

                                                COVENANTS

                  The Debtor covenants and agrees that until all obligations and
liabilities in respect of the Obligations  shall have performed and paid in full
and  until  no  Standby   Letters  of  Credit  are  outstanding  or  fully  cash
collateralized and the Commitments are terminated:

Section 4.01. Perfection of Security Interests. The Debtor will, at its expense,
cause all filings and recordings and other actions  specified on Schedule 4.1 to
have been completed on or prior to the Effective Date.

Section 4.02.     Further Actions.

(a) At all times after the date hereof, the Debtor will, at its expense,  comply
with the following:

(i) as to all Receivables,  Other Intangibles,  Equipment and Inventory, it will
cause UCC financing statements and continuation statements to be filed and to be
on file in all  applicable  jurisdictions  as required  to perfect the  security
interests  granted to the Agent  hereunder,  to the extent that  applicable  law
permits perfection of a security interest by filing under the UCC;

(ii)  as to all  Proceeds,  it  will  cause  all UCC  financing  statements  and
continuation  statements  filed in accordance with clause (i) above to include a
statement or a checked box  indicating  that Proceeds of all items of Collateral
described herein are covered;

(iii) as to any amount payable under or in connection with any of the Collateral
which  shall  be or  shall  become  evidenced  by any  promissory  note or other
instrument,  the  Debtor  will  promptly  (but in no event  later  than ten (10)
Business Days after receipt of such note or instrument), pledge and deliver such
note or other  instrument to the Agent as part of the Collateral,  duly endorsed
in a manner reasonably satisfactory to the Agent;

(iv) at the request of the Agent,  the Debtor shall deliver all other Collateral
consisting  of  certificated  securities,  endorsed  for  transfer  in a  manner
reasonably  satisfactory  to the Agent (or  execute  a  securities  intermediary
account  control  agreement  to the  extent  possession  by the  Agent  of  such
securities is not feasible); and

(v) as to all Patents,  Patent licenses,  Trademarks or Trademark licenses,  the
Debtor will effect the recordation or renewal of the recordation of the security
interests of the Agent therein so as to maintain  valid and  perfected  security
interests therein under all applicable state and federal laws.

(b) Further  Assurances.  The Debtor will, from time to time and at its expense,
execute, deliver, file or record such UCC financing statements, applications for
certificates  of title  and such  other  statements,  assignments,  instruments,
documents,  agreements  or other  papers and take any other  action  that may be
necessary or desirable,  or that the Agent may reasonably  request,  in order to
create,  preserve,  perfect,  confirm or validate the  security  interest of the
Agent in the Collateral, to enable the Agent to obtain the full benefits of this
Security  Agreement  or to enable it to exercise  and enforce any of its rights,
powers and remedies hereunder,  including, without limitation, its right to take
possession of the Collateral.

(c) Signature. To the fullest extent permitted by law, the Debtor authorizes the
Agent to sign and file  financing and  continuation  statements  and  amendments
thereto with respect to the Collateral without its signature thereon.

Section 4.03. Change of Name, Identity or Structure.  The Debtor will not change
its name, identity or corporate structure in any manner and, except as set forth
on  Schedule  3.6,  will not conduct its  business  under any trade,  assumed or
fictitious  name unless it shall have given the Agent at least  forty-five  (45)
days'  prior  written  notice  thereof  and shall have taken all action (or made
arrangements to take such action  substantially  simultaneously with such change
if it is  impossible  to take such action in advance)  necessary  or  reasonably
requested  by the  Agent  to  amend  any  financing  statement  or  continuation
statement relating to the security interests granted hereby in order to preserve
such  security  interests  and to  effectuate  or maintain the priority  thereof
against all Persons.

Section 4.04.  Place of Business and Collateral.  The Debtor will not change the
location of (i) its places of business, (ii) its chief executive office or (iii)
the  office or other  locations  where it keeps or holds any  Collateral  or any
records relating thereto from the applicable  location listed on Schedule 3.4 or
3.5 unless,  prior to such change, it notifies the Agent forty-five (45) days in
advance of such change,  makes all UCC filings required by Section 4.2 and takes
all other action necessary or that the Agent may reasonably request to preserve,
perfect,  confirm and protect the security  interests granted hereby. The Debtor
will in no event  change the  location of any  Collateral  if such change  would
cause the security  interest granted hereby in such Collateral to lapse or cease
to be  perfected.  The Debtor  will at all times  maintain  its chief  executive
office within one of the forty-eight contiguous states in which Article 9 of the
uniform commercial code is in effect.

Section  4.05.  Fixtures.  The Debtor will not permit any  Equipment to become a
fixture  unless it shall  have  given the  Agent at least ten (10)  days'  prior
written  notice  thereof and shall have taken all such action and  delivered  or
caused to be delivered to the Agent all  instruments  and documents,  including,
without  limitation,  waivers and subordination  agreements by any landlords and
mortgagees, and filed all financing statements necessary or reasonably requested
by the Agent, to preserve and protect the security  interest  granted herein and
to effectuate or maintain the priority  thereof  against all Persons;  provided,
however,  that,  so long as no Event of  Default or  Potential  Event of Default
shall have  occurred  and be  continuing,  the Debtor  shall not be obligated to
comply with the provisions of this Section 4.5 with respect to the first $50,000
of Equipment (determined based on the then fair market value thereof).

Section 4.06.  Maintenance of Records.  The Debtor will keep and maintain at its
own cost and expense complete books and records relating to the Collateral which
are satisfactory to the Agent  including,  without  limitation,  a record of all
payments received and all credits granted with respect to the Collateral and all
of its other  dealings with the  Collateral.  The Debtor will mark its books and
records pertaining to the Collateral to evidence this Security Agreement and the
security interests granted hereby.  For the Agent' further security,  the Debtor
agrees  that the Agent  shall  have a special  property  interest  in all of the
Debtor's  books and records  pertaining to the  Collateral  and the Debtor shall
deliver  and  turn  over any  such  books  and  records  to the  Agent or to its
representatives at any time on demand of the Agent.

Section  4.07.  Compliance  with Laws The  Debtor  will  comply in all  material
respects with all acts, rules,  regulations,  orders,  decrees and directions of
any government or any state or local government  applicable to the Collateral or
any part  thereof or to the  operation of the  Debtor's  business  except to the
extent that the failure to comply  would not have a material  adverse  effect on
the  financial or other  condition of the Debtor;  provided,  however,  that the
Debtor may contest any act, rule, regulation,  order, decree or direction in any
reasonable  manner which shall not, in the sole opinion of the Agent,  adversely
affect the Agent's  rights or, in the case of  Collateral  located at a facility
identified on Schedule 3.7 hereto,  the first priority of its security  interest
in the Collateral.

Section 4.08. Payment of Taxes. The Debtor will pay promptly when due all taxes,
assessments and governmental charges or levies imposed upon the Collateral or in
respect of its income or  profits  therefrom,  as well as all claims of any kind
(including claims for labor, materials and supplies), except that no such charge
need be paid if (i) the  validity  thereof is being  contested  in good faith by
appropriate  proceedings and (ii) such charge is adequately  reserved against in
accordance  with  generally  accepted  accounting  principles,  as  consistently
applied.

Section 4.09.  Compliance with Terms of Accounts and Contracts.  The Debtor will
perform and comply in all material  respects with all of its  obligations  under
all agreements  relating to the Collateral to which it is a party or by which it
is bound.

Section  4.10.  Limitation on Liens on  Collateral.  The Debtor will not create,
permit or suffer to exist,  and will  defend  the  Collateral  and the  Debtor's
rights with respect  thereto  against and take such other action as is necessary
to  remove  any  Lien,  security  interest,  encumbrance,  or claim in or to the
Collateral other than the security interests created hereunder and such Liens to
the  extent  permitted  pursuant  to  Section  6.2(a)  of the  Revolving  Credit
Agreement.

Section 4.11. Limitations on Modifications of Receivables and Other Intangibles;
No Waivers or Extensions.  The Debtor will not (i) amend,  modify,  terminate or
waive any  provisions  of any material  Receivable  or Other  Intangible  in any
manner which might, when taken together with all such other Receivables or Other
Intangibles,  respectively,  materially  reduce the value of all  Receivables or
Other  Intangibles,  respectively,  in the  Collateral,  (ii)  fail to  exercise
promptly and  diligently  each and every  material right which it may have under
each  Receivable  and Other  Intangible  or (iii) fail to deliver to the Agent a
copy of each material demand,  notice or document received by it relating in any
way to any Receivable or Other Intangible.

Section  4.12.   Maintenance  of  Insurance.   The  Debtor  will  maintain  with
financially   sound  insurance   companies   licensed  to  do  business  in  the
jurisdictions  in which the  Collateral  is located  insurance  policies  on the
Inventory and Equipment in accordance  with the  provisions of Section 6.1(m) of
the Revolving Credit Agreement.

Section 4.13.  Limitations on  Dispositions  of Collateral.  The Debtor will not
directly or indirectly (through the sale of stock, merger or otherwise), without
the prior  written  consent of the Agent,  sell,  transfer,  lease or  otherwise
dispose of any of the Collateral,  or attempt, offer or contract to do so except
for (i) sales of Inventory in the ordinary course of its business for fair value
in  arm's-length  transactions  and  (ii) so long as no  Event  of  Default  (or
Potential  Event of Default) has occurred and is continuing,  dispositions  in a
commercially reasonable manner of Equipment which has become redundant, worn out
or obsolete or which should be replaced so as to improve  productivity,  so long
as the  proceeds  of any such  disposition  are (x) used to acquire  replacement
equipment  which has comparable or better utility and equivalent or better value
and which is subject to a first priority security interest in favor of the Agent
therein,  except  as  permitted  by  Section  6.2(a)  of  the  Revolving  Credit
Agreement, or (y) applied to repay the Obligations. The inclusion of Proceeds of
the Collateral under the security interests granted hereby shall not be deemed a
consent by the Agent to any sale or disposition of any Collateral  other than as
permitted by this Section 4.13.

Section 4.14. Further  Identification of Collateral.  The Debtor will furnish to
the Agent from time to time  statements and schedules  further  identifying  and
describing  the  Collateral  and  such  other  reports  in  connection  with the
Collateral as the Agent may reasonably request. The Debtor shall promptly notify
the Agent if the value of the Collateral located at the facilities identified on
Schedule 3.7 hereto is less than 80% of the value of all of the Collateral.

Section  4.15.  Notices.  The  Debtor  will  advise  the Agent  promptly  and in
reasonable detail (i) of any Lien, security interest,  encumbrance or claim made
or  asserted  against  any of the  Collateral,  other  than,  unless  reasonably
requested  by the Agent,  Liens  permitted  by Section  6.2(a) of the  Revolving
Credit  Agreement,  (ii)  of  any  material  change  in the  composition  of the
Collateral,  and (iii) of the  occurrence  of any other event which would have a
material  adverse  effect on the  aggregate  value of the  Collateral  or on the
security interests granted to the Agent in this Security Agreement.

Section 4.16.  Change of Law. The Debtor shall promptly  notify the Agent of any
change in law known to it which (i) adversely  affects or will adversely  affect
the validity,  perfection or priority of the security  interests granted hereby,
(ii)  requires  or will  require a change in the  proceedings  to be followed in
order to maintain and protect such  validity,  perfection  and priority or (iii)
could result in the Agent not having a perfected security interest in any of the
Collateral.

Section 4.17.     Right of Inspection.

(a) Access to Books and Records. The Debtor shall,  following any request by the
Agent and upon reasonable  notice,  permit the Agent or its  representatives  to
have  full  and free  access  during  normal  business  hours to all the  books,
correspondence and records of the Debtor,  and the Agent or its  representatives
may examine the same, take extracts therefrom, make photocopies thereof and have
such discussions with officers,  employees and public  accountants of the Debtor
as the Agent may deem reasonably  necessary,  and the Debtor agrees to render to
the Agent, at the Debtor's cost and expense,  such clerical and other assistance
as  may  be  reasonably  requested  with  regard  thereto.  The  Agent  and  its
representatives  shall upon  reasonable  notice and during normal business hours
also  have the  right to enter  into  and  upon any  premises  where  any of the
Inventory or the  Equipment is located for the purpose of  inspecting  the same,
observing its use or protecting the interests of the Agent therein.

(b)  Audits.  The  Debtor  shall  permit  the  Lenders,   the  Agent  and  their
representatives  and advisors to review the operations of the Debtor and perform
the audits and  examinations  as  provided  in Section  6.1(l) of the  Revolving
Credit Agreement.

     Section 4.18.  Maintenance  of Equipment.  The Debtor will, at its expense,
     maintain the Equipment in good operating condition,  ordinary wear and tear
     excepted.

Section 4.19.     Covenants Regarding Patent and Trademark Collateral.

(a)  Generally.  At  such  time as the  Debtor  shall  acquire  any  Patents  or
Trademarks,  it will comply with the terms,  covenants  and  warranties  of this
Section 4.19.

(b) Continued Use of Trademark.  The Debtor (either itself or through licensees)
will, unless the Debtor shall reasonably determine,  after consultation with the
Agent,  that a Trademark  is of  negligible  economic  value to the Debtor,  (i)
continue  to use each  Trademark  on each  and  every  Trademark  class of goods
applicable  to its current  products  and  services as  reflected in its current
catalogs,  brochures and price lists in order to maintain each Trademark in full
force and free from any claim of  abandonment  for non-use,  (ii) maintain as in
the past the quality of products  and  services  offered  under each  Trademark,
(iii) employ each Trademark with the appropriate  notice of  registration,  (iv)
not adopt or use any mark which is confusingly  similar to a colorable imitation
of any Trademark and (v) not (and not permit any licensee or sublicensee thereof
to) do any act or knowingly  omit to do any act whereby any Trademark may become
invalidated.

(c) No  Abandonment.  The Debtor will not,  unless the Debtor  shall  reasonably
determine,  after  consultation  with the Agent,  that a Patent is of negligible
economic  value to the  Debtor,  do any act,  or  knowingly  omit to do any act,
whereby any Patent may be abandoned or dedicated.

(d) Notice of Abandonment or Adverse Determinations. The Debtor shall notify the
Agent  immediately if it knows,  or has reason to know,  that any application or
registration  relating  to any  Patent or  Trademark  may  become  abandoned  or
dedicated,  or of any adverse determination or development  (including,  without
limitation,  the institution of, or any such determination or development in any
proceeding  in the United  States  Patent and  Trademark  Office or any court of
tribunal in any  country)  regarding  the  Debtor's  ownership  of any Patent or
Trademark, its right to register the same or keep and maintain the same.

(e) Filings After Notice to Agent.  In no event shall the Debtor,  either itself
or through any agent,  employee,  licensee or designee,  file an application for
registration  of any  Patent or  Trademark  with the  United  States  Patent and
Trademark  Office or any  similar  office or agency in any other  country or any
political  subdivision  thereof,  unless it promptly informs the Agent and, upon
request of the Agent, executes and delivers any and all agreements, instruments,
documents  and papers as the Agent may request to evidence the Agent's  security
interest in such Patent or Trademark and the goodwill and general intangibles of
the  Debtor  relating  thereto or  represented  thereby,  and the Debtor  hereby
constitutes the Agent its attorney-in-fact to execute and file all such writings
for the foregoing purposes, all such acts of such attorney being hereby ratified
and confirmed.

(f) Pursuit of Applications  and Maintenance of  Registrations.  The Debtor will
take all necessary  steps,  including,  without  limitation,  in any  proceeding
before the United States Patent and  Trademark  Office or any similar  office or
agency in any other country or any political  subdivision  thereof,  to maintain
and pursue each  application  (and to obtain the relevant  registration)  and to
maintain each  registration  of the Patents and  Trademarks,  including  without
limitation, filing of applications for renewal, affidavits of use and affidavits
of incontestability;  provided,  however, that no such Patent or Trademark shall
be required to be  maintained  or pursued to the extent such Patent or Trademark
is  determined  by the  Debtor,  after  consultation  with the  Agent,  to be of
negligible economic value to the Debtor.

(g) Notice of  Infringement.  If any of the Patent and  Trademark  Collateral is
infringed,  misappropriated  or  diluted  by a third  party,  the  Debtor  shall
promptly  notify the Agent after it learns thereof and shall,  unless the Debtor
shall reasonably determine,  after consultation with the Agent, that such Patent
and Trademark Collateral is of negligible economic value to the Debtor, promptly
sue for infringement, misappropriation of dilution, seek injunctive relief where
appropriate   and  recover   any  and  all   damages   for  such   infringement,
misappropriation  or  dilution,  or take such other  action as the Debtor  shall
reasonably deem appropriate  under the  circumstances to protect such Patent and
Trademark Collateral.

Section 4.20.  Termination  of Federal  Contracts.  With respect to each Federal
Contract in respect of which the Debtor is required to execute an  Assignment of
Federal  Contract in accordance with Section 4.21 hereof,  the Debtor shall give
prompt written  notice to the Agent if the U.S.  Government  shall  terminate or
threaten to  terminate  (whether  for  convenience  or default) any such Federal
Contract  with the Debtor  having a value  (including  unexercised  options)  of
$100,000 or more. In addition,  the Debtor shall give prompt  written  notice to
the Agent if the U.S.  Government  shall  terminate or threaten to terminate any
contract between the U.S.  Government and any other prime contractor under which
the  Debtor  is a  subcontractor  if the  value of such  subcontract  (including
unexercised options) is $100,000 or more.

Section 4.21. Federal Contracts.  The Debtor shall provide to the Agent, as soon
as reasonably  practicable but not later than forty-five (45) days following the
end of each Fiscal Quarter,  a report identifying each Federal Contract to which
it is a party,  having  attached  thereto  a copy of the first two pages of such
Federal  Contract  and any  amendment  thereto,  to the  extent  not  previously
provided to the Agent.  At the request of the Agent  (unless an Event of Default
shall have  occurred and be  continuing,  in which case no such request shall be
required),  the Debtor shall  execute and deliver to the Agent an  Assignment of
Federal Contract, in substantially the form of Exhibit A hereto (the "Assignment
of Federal Contract"), and execute any other instruments or take any other steps
required  by the Agent in order  that all moneys due or to become due under such
Federal  Contracts shall be assigned to the Agent and notice thereof given under
the Assignment of Claims Act, including without  limitation  delivery of Notices
of Assignments with respect to each Federal Contract as contemplated by Appendix
A to Exhibit A hereto.

Section 4.22.  Reimbursement  Obligation.  Should the Debtor fail to comply with
the provisions of this Security Agreement, the Revolving Credit Agreement or any
other agreement relating to the Collateral such that the value of any Collateral
or the validity,  perfection,  rank or value of any security interest granted to
the  Agent  hereunder  or  thereunder  is  thereby   diminished  or  potentially
diminished or put at risk (as reasonably  determined by the Agent), the Agent on
behalf of the Debtor may, but shall not be required to,  effect such  compliance
on behalf of the Debtor,  and the Debtor shall  reimburse the Agent for the cost
thereof on demand,  and interest shall accrue on such  reimbursement  obligation
from the date the relevant  costs are incurred  until  reimbursement  thereof in
full at the Default Rate.

ARTICLE V.

                                      REMEDIES; RIGHTS UPON DEFAULT

Section 5.01. UCC Rights.  In the event that any portion of the  Obligations has
been declared or becomes due and payable in accordance with the Revolving Credit
Agreement or other Credit  Documents and such  Obligations have not been paid in
full,  the Agent may in addition to all other rights and remedies  granted to it
in this Security  Agreement and in any other  instrument or agreement  securing,
guarantying,  evidencing or relating to the Obligations, exercise (i) all rights
and  remedies of a secured  party under the UCC (whether or not in effect in the
jurisdiction  where  such  rights  are  exercised)  and  (ii) all  other  rights
available to the Agent at law or in equity.

     Section 5.02.  Payments on Collateral.  Without  limiting the rights of the
     Agent under any other provision of this Security Agreement,  if an Event of
     Default shall occur and be continuing:

(i) all payments  received by the Debtor under or in connection  with any of the
Collateral  shall  be held by the  Debtor  in  trust  for the  Agent,  shall  be
segregated  from other funds of the Debtor and shall  forthwith  upon receipt by
the Debtor be turned  over to the  Agent,  in the same form as  received  by the
Debtor  (duly  indorsed  by the  Debtor  to the  Agent,  if  required  to permit
collection thereof by the Agent); and

(ii) all such  payments  received  by the  Agent  (whether  from the  Debtor  or
otherwise)  may, in the sole  discretion  of the Agent,  be held by the Agent as
collateral  security for, and/or then or at any time thereafter applied in whole
or in part by the Agent to the payment of, the expenses and the  Obligations  as
set forth in Section 5.11 hereof.

Section 5.03.  Possession of Collateral.  In  furtherance of the foregoing,  the
Debtor  expressly  agrees  that,  if an  Event of  Default  shall  occur  and be
continuing, the Agent may (i) by judicial powers, or without judicial process if
it can be done without breach of the peace, enter any premises where any of such
Collateral is or may be located and,  without  charge or liability to the Agent,
seize and remove such  Collateral from such premises and (ii) have access to and
use of the Debtor's books and records relating to such Collateral.

Section 5.04.     Sale of Collateral; Notice.

(a) Sale of Collateral.  The Debtor expressly agrees that if an Event of Default
shall occur and be continuing, the Agent, without demand of performance or other
demand or notice of any kind (except the notice  specified below of the time and
place of any public or private  sale) to or upon the Debtor or any other  Person
(all of which  demands  and/or  notices are hereby  waived by the  Debtor),  may
forthwith (i) apply the cash, if any, then held by it as collateral as specified
in Section  5.11 hereof and (ii) if there shall be no cash or such cash shall be
insufficient to pay the Obligations in full, collect,  receive,  appropriate and
realize upon the Collateral,  and/or sell, assign,  give an option or options to
purchase or otherwise  dispose of and deliver the  Collateral (or contract to do
so) or any part thereof in one or more parcels (which need not be in round lots)
at public or  private  sale,  at any  office of the Agent or  elsewhere  in such
manner as is  commercially  reasonable and, as the Agent may deem best, for cash
or on credit or for future delivery  without  assumption of any credit risk. The
Agent shall have the right upon any such public sale,  and, if the Collateral is
of a type customarily  sold in a recognized  market or is of a type which is the
subject of widely distributed  standard price quotations,  upon any such private
sale or sales,  to purchase the whole or any part of the Collateral so sold, and
thereafter to hold the same,  absolutely and free from any right or claim of any
kind. To the extent  permitted by applicable  law, the Debtor waives all claims,
damages  and  demands  against  the  Agent  arising  out  of  the   foreclosure,
repossession, retention or sale of the Collateral.

(b) Notice of Sale. Unless the Collateral threatens to decline speedily in value
or is of a type  customarily sold on a recognized  market,  the Agent shall give
the Debtor  ten (10)  days'  written  notice of its  intention  to make any such
public or private sale or sale at a broker's board or on a securities  exchange.
Such  notice  shall (i) in the case of a public  sale,  state the time and place
fixed  for  such  sale,  (ii) in the  case of sale at a  broker's  board or on a
securities  exchange,  state the board or  exchange  at which such sale is to be
made and the day on which the  Collateral,  or the portion  thereof  being sold,
will first be offered  for sale and (iii) in the case of a private  sale,  state
the day after which such sale may be consummated.  The Agent shall not obligated
to make any such sale  pursuant  to any such  notice.  The Agent may adjourn any
public or private  sale or cause the same to be  adjourned  from time to time by
announcement at the time and place fixed for the sale, and such sale may be made
at any time or place to which the same may be so  adjourned.  In the case of any
sale of all or any part of the Collateral on credit or for future delivery,  the
Collateral  so sold may be retained by the Agent until the selling price is paid
by the purchaser thereof, but the Agent shall not incur any liability in case of
the failure of such purchase to take up and pay for the  Collateral so sold and,
in the case of such failure, such Collateral may again be sold upon like notice.

(c) Special  Provisions  Relating to Sales of Securities.  The Debtor recognizes
that  the  Agent  may be  unable  to  effect  a  public  sale  of any or all the
Collateral  constituting a "security" (as such term is defined in the Securities
Act) by reason of  certain  prohibitions  contained  in the  Securities  Act and
applicable state securities laws or otherwise, and may be compelled to resort to
one or more private sales thereof to a restricted  group of purchasers that will
be obliged to agree,  among other things,  to acquire such  securities for their
own account for  investment  and not with a view to the  distribution  or resale
thereof.  The Debtor  acknowledges  and agrees  that any such  private  sale may
result in prices and other terms less  favorable than if such sale were a public
sale and, notwithstanding such circumstances,  agrees that any such private sale
shall be deemed to have been made in a commercially reasonable manner. The Agent
shall be under no obligation to delay a sale of any of Collateral constituting a
security  for the  period of time  necessary  to permit  the  issuer  thereof to
register  such  securities  for public sale under the  Securities  Act, or under
applicable state securities laws, even if such issuer would agree to do so.

Section 5.05.  Rights of Purchasers.  Upon any sale of the  Collateral  (whether
public or  private),  the Agent  shall  have the right to  deliver,  assign  and
transfer  to the  purchaser  thereof  the  Collateral  so sold.  Each  purchaser
(including  the  Agent)  at any such  sale  shall  hold the  Collateral  so sold
absolutely,  free from any claim or right of whatever kind, including any equity
or right of redemption of the Debtor who, to the extent permitted by law, hereby
specifically waives all rights of redemption, including, without limitation, any
right to redeem the Collateral  under Section 9-506 of the UCC, and any right to
a judicial or other stay or approval  which it has or may have under any law now
existing or hereafter adopted.




Section 5.06.     Additional Rights of the Agent.

(a) Right to Maintain Proceedings.  The Agent (i) shall have the right and power
to institute and maintain such suits and proceedings as it may deem  appropriate
to protect and enforce the rights  vested in it by this  Security  Agreement and
(ii) may proceed by suit or suits at law or in equity to enforce such rights and
to foreclose  upon the  Collateral and to sell all or, from time to time, any of
the   Collateral   under  the  judgment  or  decree  of  a  court  of  competent
jurisdiction.

(b)  Appointment  of  Receiver.  The Agent  shall,  to the extent  permitted  by
applicable law,  without notice to the Debtor to any party claiming  through the
Debtor,  without regard to the solvency or insolvency at such time of any Person
then liable for the  payment of any of the  Obligations,  without  regard to the
then value of the Collateral and without requiring any bond from any complainant
in such  proceedings,  be entitled as a matter of right to the  appointment of a
receiver  or  receivers  (who may be the  Agent) of the  Collateral  or any part
thereof,  pending  such  proceedings,  with such powers as the court making such
appointment  shall  confer,  and to the  entry  of an order  directing  that the
profits, revenues and other income of the property constituting the whole or any
part of the Collateral be segregated,  sequestered and impounded for the benefit
of the Agent,  and the Debtor  irrevocably  consents to the  appointment of such
receiver or receivers and to the entry of such order.

(c) No Duty to  Exercise  Rights.  In no event  shall the Agent have any duty to
exercise any rights or take any steps to preserve the rights of the Agent in the
Collateral,  nor shall the Agent be liable to the Debtor or any other Person for
any loss caused by the Agent's failure to meet any obligation imposed by Section
9-207 of the UCC or any successor provision. Without limiting the foregoing, the
Agent  shall be deemed to have  exercised  reasonable  care in the  custody  and
preservation  of the  Collateral in its possession if the Collateral is accorded
treatment  substantially equal to that which the Agent accords its own property,
it being understood that the Agent shall not have any duty or responsibility for
(i) ascertaining or taking action with respect to calls, conversions, exchanges,
maturities,  tenders or other matters relative to any Collateral, whether or not
the Agent has or is deemed to have knowledge of such matters, or (ii) taking any
necessary  steps to preserve  rights  against any  parties  with  respect to any
Collateral.

Section 5.07.     Remedies Not Exclusive, etc.

(a) Remedies Not Exclusive. No remedy conferred upon or reserved to the Agent in
this  Security  Agreement  is intended to be  exclusive  of any other  remedy or
remedies,  but every such remedy shall be cumulative and shall be in addition to
every other  remedy  conferred  herein or now or  hereafter  existing at law, in
equity or by statute.

(b)  Restoration  of Rights.  If the Agent shall have  proceeded  to enforce any
right,  remedy or power under this Security Agreement and the proceeding for the
enforcement  thereof shall have been discontinued or abandoned for any reason or
shall have been  determined  adversely  to the  Agent,  the Debtor and the Agent
shall,   subject  to  any  determination  in  such  proceeding,   severally  and
respectively  be  restored  to their  former  positions  and  rights  under this
Security Agreement,  and thereafter all rights, remedies and powers of the Agent
shall continue as though no such proceedings had been taken.

(c)  Enforcement.  All rights of action  under this  Security  Agreement  may be
enforced by the Agent without the  possession of any  instrument  evidencing any
Obligation or the production  thereof at any trial or other proceeding  relative
thereto, and any suit or proceeding  instituted by the Agent shall be brought in
its name and any judgment shall be held as part of the Collateral.

Section 5.08.     Waiver and Estoppel.

(a) No Actions to Impede Sale of Collateral. The Debtor agrees, to the extent it
may lawfully do so, that it will not at any time in any manner  whatsoever claim
or take the benefit or advantage of any appraisal,  valuation,  stay, extension,
moratorium,  turnover or redemption  law, or any law permitting it to direct the
order in which the  Collateral  shall be sold,  now or at any time  hereafter in
force  which  may  delay,   prevent  or  otherwise  affect  the  performance  or
enforcement  of this  Security  Agreement,  and  hereby  waives  all  benefit or
advantage of all such laws. The Debtor covenants that it will not hinder,  delay
or impede  the  execution  of any power  granted  to the Agent in this  Security
Agreement, any Assignment of Federal Contract or any other Credit Document.

(b) Collateral Sold As An Entirety. The Debtor, to the extent it may lawfully do
so, on behalf of itself and all who claim through or under it, including without
limitation any and all  subsequent  creditors,  vendees,  assignees and lienors,
waives  and  releases  all  rights to demand or to have any  marshalling  of the
Collateral upon any sale, whether made under any power of sale granted herein or
pursuant to judicial  proceedings or under any foreclosure or any enforcement of
this Security Agreement,  and consents and agrees that all of the Collateral may
at any such sale be offered and sold as an entirety.

(c) Waiver of  Notices.  The Debtor  waives,  to the  extent  permitted  by law,
presentment,  demand,  protest  and any notice of any kind  (except  the notices
expressly required hereunder) in connection with this Security Agreement and any
action taken by the Agent with respect to the Collateral.







Section 5.09.     Power of Attorney; Powers Coupled With An Interest.

(a) Power of Attorney.  Without limiting any other right granted hereunder,  the
Debtor hereby irrevocably constitutes and appoints the Agent, with full power of
substitution,  as its true and  lawful  attorney-in-fact  with full  irrevocable
power and  authority in the place and stead of the Debtor and in the name of the
Debtor  or in its  own  name,  from  time  to  time  in the  Agent's  reasonable
discretion,  for the  purpose  of  carrying  out  the  terms  of  this  Security
Agreement,  to take any and all  appropriate  action and to execute  any and all
documents and instruments  which may be necessary or desirable to accomplish the
purpose of this Security  Agreement and,  without limiting the generality of the
foregoing,  hereby gives the Agent the power and right, on behalf of the Debtor,
without notice to or assent by the Debtor, to do the following:

     (i)  to  pay  or  discharge  taxes,  liens,  security  interests  or  other
     encumbrances levied or placed on or threatened against the Collateral;

(ii) to effect  any  repairs  or any  insurance  called for by the terms of this
Security  Agreement or any other Credit Document,  and to pay all or any part of
the premiums therefor and the costs thereof;

(iii) upon the occurrence and  continuance of any Event of Default and otherwise
to the  extent  provided  in this  Security  Agreement,  (A) to direct any party
liable for any payment  under any of the  Collateral  to make payment of any and
all moneys due and to come due thereunder  directly to the Agent or as the Agent
shall direct,  (B) to receive  payment of and receipt for, and to demand and sue
for, any and all moneys,  claims and other  amounts due and to become due at any
time in respect of or arising out of the Collateral, (C) to sign and indorse and
receive,  take, assign and deliver, any checks,  notes,  drafts,  negotiable and
non-negotiable  instruments,  any invoices,  freight or express bills,  bills of
lading,  storage or warehouse  receipts,  drafts against  debtors,  assignments,
verifications  and  notices in  connection  with  accounts  and other  documents
relating to the  Collateral,  (D) to  commence,  settle,  compromise,  compound,
prosecute,  defend or adjust any claim,  suit, action or proceeding with respect
to, or in connection  with, the  Collateral,  (E) to sell,  transfer,  assign or
otherwise  deal in or with the  Collateral  or any part  thereof,  as fully  and
effectively  as if the Agent were the absolute  owner  thereof and (F) to do, at
its option,  but at the expense of the Debtor, at any time or from time to time,
all acts and things  which the Agent deems  necessary  to  protect,  preserve or
realize upon the Collateral and the Agent's security interest therein,  in order
to effect the intent of this Security Agreement, all as fully and effectively as
the Debtor might do.

(b) Powers Coupled With an Interest.  All authorizations and agencies granted or
provided  herein with respect to the  Collateral,  including the powers  granted
under clause (a) of this Section 5.9, are irrevocable and powers coupled with an
interest.

Section 5.10. Certain Provisions Relating to Securities.  Solely with respect to
any Collateral  constituting a "security" (as defined in the Securities Act), if
an Event of Default shall have occurred and be continuing,  all such  securities
(as defined in the Securities Act)  constituting a part of the Collateral shall,
at the  request  of the  Agent,  be  registered  in the name of the Agent or its
nominee,  and the Agent or its nominee may  thereafter  exercise (i) all voting,
corporate and other rights,  powers and privileges pertaining to such Collateral
at any meeting of shareholders of the issuer thereof or otherwise,  and (ii) any
and all  rights of  conversion,  exchange,  subscription  and any other  rights,
privileges or options  pertaining to such  Collateral as if it were the absolute
owner  thereof  (including,  without  limitation,  the right to  exchange at its
discretion  any  and  all  such  Collateral  upon  the  merger,   consolidation,
reorganization, recapitalization or other fundamental change in the structure of
any such  issuer,  or upon the exercise by the Debtor or the Agent of any right,
privilege or option pertaining to such Collateral,  and in connection therewith,
the right to deposit and deliver any and all such Collateral with any committee,
depositary, transfer agent, registrar or other designated agency upon such terms
and conditions as it may determine), all without liability except to account for
property  actually  received  by it and except as  provided  in  Section  5.6(c)
hereof,  but the Agent  shall  have no duty to the Debtor to  exercise  any such
right, privilege or option and shall not be responsible for any failure to do so
or delay in so doing.

     Section 5.11.  Application of Monies. The proceeds of any sale of, or other
     realization upon, all or any part of the Collateral shall be applied by the
     Agent in the following order of priority:

                  first,  to  payment  of the  expenses  of such  sale or  other
realization,  including reasonable  compensation to the Agent and its agents and
counsel,  and all  expenses,  liabilities  and advances  incurred or made by the
Agent, its agents and counsel in connection  therewith or in connection with the
care, safekeeping or otherwise of any or all of the Collateral;

     second,  to  payment  of the  Obligations,  in such  order as the Agent may
     elect; and

                  third, any surplus then remaining shall be paid to the Debtor,
or its  successors  or assigns,  or to  whomsoever  may be lawfully  entitled to
receive the same (including  pursuant to Section 9-504(1)(C) of the UCC) or as a
court of competent jurisdiction may direct.

ARTICLE VI.

                                              MISCELLANEOUS

Section 6.01. Notices. All notices, requests and other communications to a party
hereunder  shall be in writing  and shall be given to such party at its  address
set forth on the  signature  page hereof or such other address as such party may
hereafter  specify for that  purpose by notice to the other.  Each such  notice,
request or other  communication shall be effective (i) in the case of telephonic
notice (to the extent  expressly  permitted  hereunder),  when made, (ii) in the
case of notice delivered by overnight  express  courier,  one Business Day after
the Business Day such notice was delivered to such courier, (iii) in the case of
notice  delivered by first class mail, three Business Days after being deposited
in the mail,  postage  prepaid,  return receipt  requested,  (iv) in the case of

means of telecommunication, when sent provided confirmation of receipt or answer
back has been  received,  in each  case if  addressed  to any  party  hereto  as
provided  herein.  Rejection or refusal to accept,  or the  inability to deliver
because of a changed address of which no notice was given,  shall not affect the
validity of notice given in accordance with this section.

Section 6.02.  No Waiver;  Cumulative  Remedies.  The Agent shall not by any act
(except by a written  instrument  pursuant  to Section  6.3 hereof) be deemed to
have waived any right or remedy hereunder. No failure to exercise, nor any delay
in exercising,  on the part of the Agent any right, power or privilege hereunder
shall operate as a waiver thereof.  No single or partial  exercise of any right,
power or  privilege  hereunder  shall  preclude  any other or  further  exercise
thereof or the exercise of any other right, power or privilege.  A waiver by the
Agent  of any  right  or  remedy  hereunder  on any one  occasion  shall  not be
construed as a bar to any right or remedy which the Agent would  otherwise  have
on any future occasion.  The rights and remedies herein provided are cumulative,
may be  exercised  singly or  concurrently  and are not  exclusive  of any other
rights or remedies provided by law.

Section 6.03.  Amendments  and Waivers.  None of the terms or provisions of this
Security Agreement may be amended,  supplemented or otherwise modified except by
a written  instrument  executed by the Debtor and the Agent;  provided  that any
provision of this  Security  Agreement may be waived by the Agent in a letter or
agreement  executed by the Agent or by telex or facsimile  transmission from the
Agent.

Section 6.04.  Successors and Assigns. The provisions of this Security Agreement

written consent of the Agent.

     Section 6.05.  Governing Law. THIS SECURITY  AGREEMENT SHALL BE GOVERNED BY
     AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE  COMMONWEALTH OF VIRGINIA,
     OTHER THAN ITS LAWS RESPECTING  CHOICE OF LAW OTHER THAN THOSE CONTAINED IN
     THE UCC.

Section 6.06.     Limitation by Law; Severability.

(a) All rights,  remedies and powers provided in this Security  Agreement may be
exercised  only to the extent  that the  exercise  thereof  does not violate any
applicable  provision of law, and all the provisions of this Security  Agreement
are intended to be subject to all applicable  mandatory  provisions of law which
may be controlling  and to be limited to the extent  necessary so that they will
not render this Security Agreement  invalid,  unenforceable in whole or in part,
or not entitled to be recorded,  registered or filed upon the  provisions of any
applicable law.

(b) If any provision hereof is invalid and  unenforceable  in any  jurisdiction,
then, to the fullest extent  permitted by law, (i) the other  provisions  hereof
shall  remain  in full  force  and  effect  in such  jurisdiction  and  shall be
liberally  construed in favor of the Agent in order to carry out the  intentions
of the parties  hereto as nearly as may be possible and (ii) the  invalidity  or
unenforceability  of any provision hereof in any  jurisdiction  shall not affect
the validity or enforceability of such provision in any other jurisdiction.

Section  6.07.  Counterparts.  This  Security  Agreement  may be executed in any
number of counterparts and by different parties hereto on separate counterparts,
each complete set of which, when so executed and delivered by all parties, shall
be an original,  but all such counterparts shall together constitute but one and
the same instrument.

Section 6.08. Expenses of the Agent. The Debtor shall pay to the Agent from time
to time upon demand,  all of the costs and expenses incurred by the Agent or any
Lender (including,  without limitation, the reasonable fees and disbursements of
counsel  and any  amounts  payable  by the  Agent or any  Lender to any of their
respective   agents)  (i)  arising  in  connection   with  the   administration,
modification, amendment, waiver or termination of this Security Agreement or any
document or agreement  contemplated hereby or any consent or waiver hereunder or
thereunder  or (ii)  incurred  in  connection  with the  administration  of this
Security  Agreement,  or any document or agreement  contemplated  hereby,  or in
connection  with the  administration,  sale or other  disposition  of Collateral
hereunder  or  under  any  document  or  agreement  contemplated  hereby  or the
preservation,  protection or defense of the rights of the Agent or any Lender in
and to the Collateral.

Section  6.09.  Indemnification.   The  Debtor  shall  at  all  times  hereafter
indemnify, hold harmless and, on demand, reimburse the Agent and the Lenders and
their  respective  subsidiaries,   affiliates,  successors,  assigns,  officers,
directors,   employees  and  agents,  and  their  respective  heirs,  executors,
administrators, successors and assigns (all of the foregoing parties, including,
but not limited to, the Agent, being hereinafter collectively referred to as the
"Indemnities" and individually as an "Indemnitee") from, against and for any and
all liabilities,  obligations,  claims, damages, actions,  penalties,  causes of
action, losses, judgments, suits, costs, expenses and disbursements,  including,
without  limitation,  attorney's  fees  (any  and  all  of the  foregoing  being
hereinafter  collectively referred to as the "Liabilities" and individually as a
"Liability")  which  the  Indemnitees,  or  any  of  them,  might  be or  become
subjected, by reason of, or arising out of the preparation, execution, delivery,
modification,  administration  or enforcement  of, or performance of the Agent's
rights  under,  this  Security  Agreement or any other  document,  instrument or
agreement  contemplated  hereby or executed in  connection  herewith;  provided,
however, that the Debtor shall not be liable to any Indemnitee for any Liability
caused solely by the gross negligence or willful  misconduct of such Indemnitee.
In no event shall any  Indemnitee,  as a condition to enforcing its rights under
this Section 6.9 or  otherwise,  be obligated to make a claim  against any other
Person (including,  without  limitation,  the Agent) to enforce its rights under
this Section 6.9.

Section 6.10.  Termination;  Survival.  This Security  Agreement shall terminate
when the security interests granted hereunder have terminated and the Collateral
has been  released as  provided  in Section  2.6;  provided,  however,  that the
obligations  of the Debtor under Section 4.22 and the provisions of this Article
6 shall survive any such termination.

Section  6.11.  Judicial  Proceedings;   Waiver  of  Jury  Trial.  Any  judicial
proceeding  brought  against  the Debtor  with  respect to any Credit  Agreement
Related  Claim hereby may be brought in any court of competent  jurisdiction  in
the  Commonwealth  of Virginia,  County of Fairfax,  or any Federal court in the
Eastern  District of Virginia,  and, by execution  and delivery of this Security
Agreement,   the  Debtor  (a)  accepts,   generally  and  unconditionally,   the
nonexclusive  jurisdiction  of such courts and any related  appellate  court and
irrevocably  agrees to be bound by any judgment  rendered  thereby in connection
with any Credit Agreement Related Claim and (b) irrevocably waives any objection
it may now or hereafter have as to the venue of any such  proceeding  brought in
such a court or that such a court is an  inconvenient  forum.  The Debtor hereby
waives personal  service of process and consents that service of process upon it
may be made by certified or registered mail,  return receipt  requested,  at its
address specified or determined in accordance with the provisions of Section 6.1
hereof,  and service so made shall be deemed completed on the earlier of (x) the
receipt  thereof and (y) if sent by registered or certified mail (return receipt
requested),  the fifth (5th) Business Day after such service is deposited in the
mail. Nothing herein shall affect the right of the Agent to serve process in any
other  manner  permitted  by law or shall  limit the right of the Agent to bring
proceedings  against  the  Debtor in the courts of any other  jurisdiction.  Any
judicial proceeding by the Debtor against the Agent relating to or involving any
Credit  Agreement  Related Claim hereby shall be brought only in a court located
in the Commonwealth of Virginia,  County of Fairfax, or the Federal court in the
Eastern  District of Virginia.  THE DEBTOR AND THE AGENT HEREBY  UNCONDITIONALLY
WAIVE  TRIAL  BY JURY IN ANY  JUDICIAL  PROCEEDING  TO WHICH  THEY  ARE  PARTIES
INVOLVING ANY CREDIT AGREEMENT RELATED CLAIM.

Section  6.12.  Integration.  This  Security  Agreement  and  the  other  Credit
Documents  constitute  the entire  agreement  of the  Agent,  the  Lenders,  the
Borrower and the other Credit  Parties with respect to the subject matter hereof
and  thereof,  and  there  are no  promises,  undertakings,  representations  or
warranties by the Agent or any Lender  relative to the subject  matter hereof or
thereof not  expressly  set forth or  referred to herein or in the other  Credit
Documents.

Section 6.13.  Authority of Agent. The Debtor  acknowledges  that the rights and
responsibilities  of the Agent under this Security Agreement with respect to any
action  taken by the Agent or the exercise or  non-exercise  by the Agent of any
option,  voting right,  request,  judgment or other right or remedy provided for
herein or resulting or arising out of this Security  Agreement shall, as between
the Agent and the Lenders,  be governed by the Revolving Credit Agreement and by
such other  agreements with respect thereto as may exist from time to time among
them, but, as between the Agent and the Debtor,  the Agent shall be conclusively
presumed to be acting as agent for the Lenders with full and valid  authority so
to act or refrain from acting, and the Debtor shall not be under any obligation,
or entitlement, to make any inquiry respecting such authority.

                               Security Agreement

                                     FORM OF
                         ASSIGNMENT OF FEDERAL CONTRACT


                  This  ASSIGNMENT OF FEDERAL  CONTRACT,  dated as of _____,  __
(the "Agreement"),  is made by PUTNAM,  HAYES & BARTLETT,  INC., a Massachusetts
corporation (the "Assignor"), in favor of NATIONSBANK,  N.A., a national banking
association (the "Agent"), in its capacity as Agent for the lenders from time to
time a party to the  Revolving  Credit  Agreement  (as  defined in the  Security
Agreement referred to below).

                                               W I T N E S S E T H:

                  WHEREAS,   the  Assignor  has  secured   certain   obligations
undertaken  by Hagler  Bailly,  Inc.  pursuant to the  provisions  of a Security
Agreement,  dated as of  ___________________,  ____ (as the same may be amended,
supplemented or otherwise modified from time to time, the "Security Agreement"),
by and between the Assignor and the Agent; and

                  WHEREAS,  the  Assignor  is a party to,  and from time to time
will  become  entitled  to  receive  moneys  under and by  virtue  of, a certain
contract  with,  involving or for the benefit of the United States of America or

called the "Contract"); and

                  WHEREAS,  pursuant to the Security Agreement, the Assignor has
undertaken to effectuate the  assignment(s)  and other actions  contemplated  by
this Agreement.

                  NOW,  THEREFORE,  in  consideration  of the premises and other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the Assignor covenants and agrees as follows:

         1. Incorporation By Reference. The provisions of the Security Agreement
are  incorporated  herein by  reference,  and the terms  defined in the Security
Agreement are used herein with the same meanings.

         2.  Representations.  The Assignor represents and warrants to the Agent
that (a) the Contract is legal,  valid and binding on the  Assignor  and, to its
knowledge,  the other parties thereto,  is in full force and effect,  and is not
evidenced  by any  chattel  paper or  instrument,  (b) upon due  filing  of this
Agreement,  together  with a Notice of Assignment  substantially  in the form of
Appendix A hereto with the authorized representative, the execution and delivery
of this Agreement does not violate and is not in conflict with the provisions of
the  Contract,  (c) there has been no default on the part of the Assignor or any
other party to the Contract, (d) the Assignor has made no previous assignment of
the  Contract to any person and knows of no fact or defense that will render the
moneys due or to be due  thereunder  uncollectible,  (e) no financing  statement
covering  the  Contract  is on  file  in  any  public  office  except  financing
statements in favor of the Agent,  (f) no set-off or  counterclaim to any moneys
due or to become  due  under the  Contract  exists  on the date  hereof,  and no
agreement  has been made with any person  under which any  deduction or discount
may be claimed,  and (g) the address of the office where the Assignor  keeps its
records concerning the Contract is ____________________.

         3. Collateral. As security and collateral for the payment of all of the
Obligations  (defined in the Security  Agreement)  and for  performance  of, and
compliance  with,  by the  Assignor,  all of the terms,  covenants,  conditions,
stipulations,  and  agreements  contained in this  Agreement and in the Security
Agreement,  the Assignor hereby assigns to the Agent,  and grants to the Agent a
lien on and  security  interest  in,  all  moneys  and claims for moneys now and
hereafter  due and to  become  due to the  Assignor  under or by  reason  of the
Contract,  together  with all  cash and  non-cash  proceeds  thereof;  provided,
however,  that nothing  contained  herein shall impose upon the Agent any of the
obligations or liabilities of the Assignor under the Contract.

         4. Covenants. Until payment and performance in full of the Obligations,
the Assignor covenants as follows:

(c) The  Assignor  shall  place  on any and all  vouchers,  invoices,  or  other
instruments demanding payment under the Contract the direction that such payment
is to be made to the Agent in accordance with Section 5 of this Agreement.

(d) The Assignor shall promptly upon request execute,  acknowledge,  and deliver
any  notice,  financing  statement,   renewal,   affidavit,   deed,  assignment,
continuation statement,  security agreement,  certificate,  or other document as
the  Agent  may  require  in  order to  perfect,  preserve,  maintain,  protect,
continue, and/or extend the assignment, lien, and security interest of the Agent
under this  Agreement and its priority.  The Assignor  shall pay to the Agent on
demand all taxes,  costs, and expenses  incurred by the Agent in connection with
the  preparation,  execution,  recording,  and  filing of any such  document  or
instrument  mentioned  aforesaid,  and such taxes,  costs,  and  expenses  shall
constitute  and become a part of the  Obligations.  A carbon,  photographic,  or
other  reproduction  of  a  security  agreement  or  a  financing  statement  is
sufficient as a financing statement.

(e) The Assignor shall fully,  promptly,  and faithfully comply with and perform
its  obligations  and duties  under the  Contract in  accordance  with the terms
thereof and will make no changes or  amendments  to the Contract or terminate or
cancel the  Contract  without the prior  written  consent of the Agent except as
permitted by the Security  Agreement.  In the event that any change,  amendment,
termination  or  cancellation  of  the  Contract  is  made  or  effected  by the
Government,  the Assignor  will  promptly  notify the Agent thereof and promptly
furnish to the Agent a copy of any  document or  agreement  evidencing  any such
change, amendment, termination, or cancellation.

(f)      The Assignor will promptly

     (i) furnish to the Agent all information received by the Assignor affecting
     the moneys due and to become due under the Contract,

     (ii)  inform the Agent of any delay in  performance  of, or claims  made in
     regard to, the Contract, and

(iii) notify the Agent in writing of the failure of any party to the Contract to
perform any of its  obligations  thereunder and any rejection of any performance
rendered by the Assignor under or in connection with the Contract.

(g) The  Assignor  will at all times  keep  accurate  and  complete  records  of
performance  by the Assignor  under the  Contract,  and the Agent and its agents
shall have the right,  during normal business hours and upon reasonable  advance
notice,  to call at the place or places of business of the Assignor at intervals
to be  determined  by the Agent,  and without  hindrance  or delay,  to inspect,
audit,  check,  and make extracts  from the books,  records,  journals,  orders,
receipts,  correspondence,  and other data  relating  to the  Contract or to any
other transactions between the parties hereto related to the Contract.

         5. Payments. The Assignor hereby authorizes,  empowers, and directs the
Government to draw all checks,  drafts,  or other  instruments  representing the
payments of money due the Assignor under the Contract  (herein called the "Items
of Payment") to the order of  NationsBank,  N.A.,  assignee of Assignor,  and to
send  the  same  (i)  if by  mail,  to ,  (ii)  if by  electronic  transfer,  to
NationsBank, N.A. for the account of ________________, Bank Account #__________,
Agent ABA#_________,  or (iii) if by wire transfer, to NationsBank, N.A. for the
account of  _________________________,  Bank Account #_______,  ABA#___________.
If, despite this  direction,  any  instruments or checks  representing  payments
should be delivered to the Assignor,  the Assignor will immediately  endorse and
deliver such  instruments or checks to the order of the Agent. The Assignor does
hereby  irrevocably  (subject  to  revocation  with the  consent  of the  Agent)
designate and appoint (which appointment is coupled with an interest) the Agent,
and the Agent's  successors in interest by operation of law, the Assignor's true
and  lawful  attorney  with  power  irrevocable  for  the  Assignor  and  in the
Assignor's  name,  place,  and  stead,  but at the sole cost and  expense of the
Assignor,  to receive,  endorse,  and collect all Items of Payment,  and to ask,
demand,  receive,  receipt,  and give acquittances for any and all amounts which
may be payable  or which  become due and  payable  by the  Government  under the
Contract,  and in the Agent's  discretion to file any claim or to take any other
action  or  proceeding,  either  in the  Agent's  own name or in the name of the
Assignor or otherwise,  which to the Agent or any successor in interest  thereof
may seem  necessary  or  desirable in order to collect or endorse the payment of
any and all amounts now due or owing or which may  hereafter be or become due or
owing on account of the  Contract.  All Items of Payment  received  by the Agent
pursuant  hereto  which are  finally  paid in cash or solvent  credits  shall be
applied  against the  Obligations  as provided in the  Security  Agreement.  Any
portion of the Items of Payment  which the Agent elects not to so apply shall be
paid over to the  Assignor  or to  whomsoever  shall be entitled  thereto  under
applicable  law,  including  pursuant  to  Section  9-504(1)(C)  of the  Uniform
Commercial Code of the Commonwealth of Virginia.

         6.  No  Waiver.   Neither  this  Agreement  nor  any  term,  condition,
representation,  warranty, covenant, or agreement hereof may be changed, waived,
discharged,  or terminated  orally,  but only by an instrument in writing by the
party against whom such change, waiver, discharge, or termination is sought.

         7. Governing law. THIS AGREEMENT  SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE  WITH THE LAWS OF THE  COMMONWEALTH  OF VIRGINIA,  WITHOUT  REGARD TO
PRINCIPLES OF CONFLICTS OF LAWS.

         8. Gender.  Whenever used herein, the singular number shall include the
plural,  the plural the singular,  and the use of the  masculine,  feminine,  or
neuter gender shall include all genders.

         9.  Counterparts.  This  Agreement  may be  executed  in any  number of
duplicate  originals,  each of  which  shall  be an  original  but all of  which
together shall constitute one and the same instrument.

         10. Paragraph  Headings.  The paragraph  headings of this Agreement are
for  convenience  only and  shall not limit or  define  the  provisions  of this
Agreement.

payment of all Obligations,  howsoever  created,  arising or evidenced,  whether
direct or indirect,  absolute or contingent, now or hereafter existing or due or
to become  due,  whether at  maturity  or upon  acceleration  or  otherwise,  in
accordance with the terms thereof and to secure the due and punctual performance
of all of the  Obligations  and in order to induce the Agent and the  Lenders to
enter into the Revolving  Credit Agreement and the other Credit  Documents,  the
Debtor hereby pledges,  assigns,  delivers,  conveys and transfers to the Agent,
for the ratable benefit of the Lenders, and grants to the Agent, for the ratable
benefit of the Lenders, a first priority and continuing security interest in and
lien on, all of the  Debtor's  right,  title and  interest  in, to and under the
following, whether now existing or hereafter acquired (the "Collateral"):

(i)      all Receivables;

(ii)     all Other Intangibles;

(iii)    all Equipment;

(iv)     all Inventory;

(v) to the  extent  not  included  in the  foregoing,  all  securities  (whether
certificated or uncertificated)  and all financial assets,  whether now existing
or hereafter arising, including, without limitation, all capital stock issued by
any Person and held by Debtor,  and all  partnership  interests,  whether in the
nature of a joint venture,  limited liability company member's interest,  master
limited partnership, teaming arrangement or otherwise;

(vi) to the extent not included in the foregoing,  all other personal  property,
whether  tangible or intangible,  and wherever located whether within or outside
of the United  States,  including,  but not  limited  to,  the  balance of every
deposit  account now or hereafter  existing of the Debtor with any bank or other
financial  institution and all monies of the Debtor and all rights to payment of
money of the Debtor;

(vii) to the extent not  included  in the  foregoing,  all  books,  ledgers  and
records and all computer  programs,  tapes,  discs, punch cards, data processing
software,  transaction  files,  master  files and  related  property  and rights
(including computer and peripheral equipment) necessary or helpful in enforcing,
identifying or establishing any item of Collateral; and

(viii) to the extent not otherwise included, all Proceeds and products of any or
all of the foregoing, whether existing on the date hereof or arising hereafter;

provided,  however,  notwithstanding  anything to the contrary contained herein,
the  Debtor is not  assigning,  pledging  or  otherwise  encumbering  under this
Security Agreement its interests in any Federal Contract to which it is a party,
or in accounts or receivables due to Debtor under such Federal Contract,  to the
extent,  but only to the extent,  such assignment,  pledge or other  encumbrance
would  breach or violate or would cause Debtor to breach or violate such Federal
Contract or statutes or regulations applicable thereto, it being understood that
this proviso does not apply to, or in any way limit, Debtor's assignment, pledge
or encumbrance of Proceeds of all Federal Contracts to which it is a party.

Section  2.02.  Continuing  Liability  of the  Debtor.  Anything  herein  to the
contrary notwithstanding,  the Debtor shall remain liable to observe and perform
all the  terms and  conditions  to be  observed  and  performed  by it under any
contract,   agreement,   warranty  or  other  obligation  with  respect  to  the
Collateral;  and  shall do  nothing  to impair  the  security  interests  herein
granted.  The Agent shall not have any  obligation  or liability  under any such
contract,  agreement, warranty or obligation by reason of or arising out of this
Security  Agreement  or the receipt by the Agent of any payment  relating to any
Collateral,  nor shall the Agent be  required  to perform or fulfill  any of the
obligations of the Debtor with respect to the Collateral, to make any inquiry as
to the nature or sufficiency of any payment received by it or the sufficiency of
the  performance  of any party's  obligations  with  respect to any  Collateral.
Furthermore,  the  Agent  shall not be  required  to file any claim or demand to
collect any amount due or to enforce the performance of any party's  obligations
with respect to, the Collateral.

Section 2.03.     Sales and Collections.

(a) Sales of  Inventory  in the  Ordinary  Course  of  Business.  The  Debtor is
authorized (i) to sell in the ordinary course of its business for fair value and
on an  arm's-length  basis  any of its  Inventory  normally  held by it for such
purpose and (ii) to use and consume, in the ordinary course of its business, any
raw materials,  supplies and materials normally held by it for such purpose. The
Agent may, upon the occurrence of any Event of Default, without cause or notice,
curtail or terminate such authority at any time.

(b) Collection of Receivables. The Debtor is authorized to collect amounts owing
to it with respect to the Collateral, except as otherwise provided in connection
with the Assignment of Federal Contract, if any as provided herein. However, the
Agent may, upon and during the continuance of an Event of Default or a Potential
Event of Default, notify Account Debtors obligated to make payments under any or
all Receivables or Other  Intangibles that the Agent has a security  interest in
such Collateral and that payments shall be made directly to the Agent.  Upon the
request of the Agent upon and during the continuance of an Event of Default or a
Potential  Event of Default,  as the case may be, the Debtor will so notify such
Account  Debtors  and  will  execute  such  contract  assignments,   notices  of
assignment or other  documents as may be required by such Account  Debtors.  The
Debtor will use all  reasonable  efforts to cause each Account  Debtor to comply
with the foregoing  instruction.  In furtherance  of the  foregoing,  the Debtor
authorizes the Agent upon and during the continuance of an Event of Default or a
Potential  Event of Default (i) to ask for,  demand,  collect,  receive and give
acquittances  and  receipts  for any and all amounts due and to become due under
any Collateral and in the name of the Debtor or its own name or otherwise,  (ii)
to  take  possession  of,  endorse  and  collect  any  checks,   drafts,  notes,
acceptances  or other  instruments  for the  payment  of  monies  due  under any
Collateral  and (iii) to file any claim or take any other action in any court of
law or equity or  otherwise  which it may deem  appropriate  for the  purpose of
collecting  any  amounts  due under any  Collateral.  The  Agent  shall  have no
obligation  to obtain or record any  information  relating to the source of such
funds or the obligations in respect of which payments have been made.

Section 2.04.     Segregation of Proceeds.

(a) Cash Collateral  Account  Maintained by Agent. Upon an Event of Default or a
Potential  Event of  Default,  the Agent shall have the right at any time during
the  continuance  thereof to cause to be opened and  maintained at the office of
the Agent in McLean,  Virginia a  non-interest  bearing  bank account (the "Cash
Collateral  Account") which will contain only Proceeds.  Any "cash proceeds" (as
such term is defined  in  Section  9-306(1)  of the UCC)  received  by the Agent
directly from Account  Debtors  obligated to make payments under  Receivables or
Other Intangibles  pursuant to Section 2.3 hereof or from the Debtor pursuant to
clause (b) of this Section 2.4,  whether  consisting of checks,  notes,  drafts,
bills of exchange, money orders,  commercial paper or other Proceeds received on
account of any  Collateral,  shall be promptly  deposited in the Cash Collateral
Account, and until so deposited shall be held in trust for the Agent as property
of the  Agent  and shall not be  commingled  with any  funds of the  Debtor  not
constituting  Proceeds  of  Collateral.  The name in which  the Cash  Collateral
Account is carried shall clearly  indicate that the funds deposited  therein are
the  property  of the  Debtor,  subject to the  security  interest  of the Agent
hereunder. Such Proceeds, when deposited,  shall continue to be security for the
Obligations   and  shall  not  constitute   payment  thereof  until  applied  as
hereinafter  provided.  The Agent shall have sole  dominion and control over the
funds deposited in the Cash Collateral Account,  and such funds may be withdrawn
therefrom only by the Agent.

(b) Deposit of  Proceeds  by the Debtor.  Upon notice by the Agent to the Debtor
that the Cash  Collateral  Account has been  opened,  the Debtor shall cause all
cash  Proceeds  collected  by it to be  delivered  to the Agent  forthwith  upon
receipt,  in the original  form in which  received  (with such  endorsements  or
assignments as may be necessary to permit collection  thereof by the Agent), and
for such  purpose the Debtor  hereby  irrevocably  authorizes  and  empowers the
Agent,  its officers,  employees and  authorized  agents to endorse and sign the
name of the Debtor on all checks, drafts, money orders or other media of payment
so delivered,  and such endorsements or assignments shall, for all purposes,  be
deemed to have been made by the Debtor prior to any  endorsement  or  assignment
thereof by the Agent.  The Agent may use any  convenient or customary  means for
the purpose of collecting  such checks,  drafts,  money orders or other media of
payment.

Section 2.05.  Verification  of  Receivables.  The Agent shall have the right to
make test  verifications of Receivables in any reasonable manner and through any
medium that it considers  advisable,  and the Debtor  agrees to furnish all such
assistance and  information  as the Agent may  reasonable  require in connection
therewith.  The Debtor at its expense will cause its chief financial  officer to
furnish to the Agent at any reasonable  time and from time to time promptly upon
the Agent's reasonable request,  the following reports:  (i) a reconciliation of
all Receivables, (ii) an aging of all Receivables, (iii) trial balances and (iv)
a test verification of such Receivables as the Agent may request.

Section 2.06.     Release of Collateral.

(a) Security  Interest of Agent Ceases Upon Permitted  Dispositions.  The Debtor
may sell or realize upon or transfer or otherwise  dispose of Collateral only to
the extent permitted by Section 4.13, and the security interests of the Agent in
such  Collateral so sold,  realized upon or disposed of (but not in the Proceeds
arising from such sale, realization or disposition) shall cease immediately upon
such sale, realization or disposition, without any further action on the part of
the Agent.  The Agent,  if requested in writing by the Debtor but at the expense
of the Debtor,  is hereby  authorized  and  instructed to deliver to the Account
Debtor or the purchaser or other transferee of any such Collateral a certificate
stating  that the Agent no longer  has a  security  interest  therein,  and such
Account Debtor or such purchaser or other  transferee  shall be entitled to rely
conclusively on such certificate for any and all purposes.

(b) Filing of  Termination  Statements.  Upon the  payment in full of all of the
Obligations  and if  there  is no  commitment  by any  Lender  to  make  further
advances,  incur obligations or otherwise give value, the Agent will (as soon as
reasonably  practicable  after receipt of notice from the Debtor  requesting the
same but at the  expense  of the  Debtor)  deliver  to the  Debtor  (i) for each
jurisdiction  in  which a UCC  financing  statement  is on file to  perfect  the
security  interests  granted to the Agent  hereunder,  a  termination  statement
(appropriately  completed)  to the  effect  that the  Agent no  longer  claims a
security interest under such financing statement,  and (ii) such other documents
as  the  Debtor  shall  reasonably  request   evidencing   satisfaction  of  the
Obligations  and the  release  of the  security  interests  granted to the Agent
hereunder.

ARTICLE III.

                                      REPRESENTATIONS AND WARRANTIES

         The Debtor represents and warrants that:

Section 3.01. Title to Collateral.  Except for the security interests granted to
the Agent  pursuant to this  Security  Agreement  and as otherwise  permitted by
Section 6.2(a) of the Revolving Credit  Agreement,  the Debtor is the sole owner
of each item of the Collateral,  having good and marketable title thereto,  free
and clear of any and all Liens.

Section 3.02.     Validity, Perfection and Priority of Security Interests.

(a) By complying  with Section 4.1 hereof,  the Debtor will have created a valid
security  interest in favor of the Agent in all existing  Collateral  and in all
identifiable  Proceeds of such  Collateral,  which security  interest (except in
respect of  Collateral  not located at a facility  identified  on  Schedule  3.7
hereto  and motor  vehicles  for  which the  exclusive  manner of  perfecting  a
security interest therein is by noting such security interest in the certificate
of title in accordance with local law) would be prior to the claims of a trustee
in bankruptcy under Section 544(a) of the Bankruptcy Code. Continuing compliance
by the Debtor  with the  provisions  of Section  4.2 hereof will also (i) create
valid security interests in all Collateral acquired after the date hereof and in
all  identifiable  Proceeds  of such  Collateral  and (ii) cause  such  security
interests in all Collateral and in all Proceeds which are (A) identifiable  cash
Proceeds of  Collateral  covered by  financing  statements  required to be filed
hereunder,  (B)  identifiable  Proceeds  in  which a  security  interest  may be
perfected  by such  filing  under  the UCC and  (C)  any  Proceeds  in the  Cash
Collateral Account to be duly perfected under the UCC, in each case prior to the
claims of a trustee in bankruptcy  under the Bankruptcy  Code (except in respect
of Collateral not located at a facility identified on Schedule 3.5 hereto).

(b) The  security  interests  of the  Agent  in the  Collateral  located  at the
facilities identified on Schedule 3.5 hereto rank first in priority.  Other than
financing   statements  or  other  similar  documents  perfecting  the  security
interests  in favor of the  Agent,  no  financing  statements,  deeds of  trust,
mortgages or similar documents covering all or any part of the Collateral are on
file or of record in any  government  office in any  jurisdiction  in which such
filing or recording  would be  effective to perfect a security  interest in such
Collateral,  nor is any of the Collateral in the possession of any Person (other
than the Debtor) asserting any claim thereto or security interest therein.

Section 3.03.  Enforceability of Receivables and Other Intangibles.  To the best
knowledge of the Debtor,  each  Receivable  and Other  Intangible is a valid and
binding obligation of the related Account Debtor in respect thereof, enforceable
in accordance with its terms,  except as such  enforceability  may be limited by
applicable bankruptcy,  insolvency,  reorganization,  moratorium or similar laws
affecting  the  enforcement  of  creditors'  rights  generally  and  by  general
provisions of equity (regardless of whether such enforceability is considered in
a  proceeding  in equity or at law),  and  complies  with any  applicable  legal
requirements.

Section 3.04.  Place of Business.  Schedule 3.4  correctly  sets forth the chief
executive  office and principal  place of business of the Debtor and the offices
of the Debtor where records  concerning  Receivables  and Other  Intangibles are
kept.

Section 3.05.  Location of  Collateral.  Schedule 3.5  correctly  sets forth the
location of all Equipment and Inventory,  other than rolling stock, aircraft and
goods in transit.  Except as otherwise  specified in Schedule 3.5, all Inventory
and Equipment  has been located at the address  specified on Schedule 3.5 at all
times during the  four-month  period prior to the date hereof while owned by the
Debtor.  All Inventory has been and will be produced in compliance with the Fair
Labor Standards Act, 29 U.S.C.  ss.ss.  201-219,  except for such non-compliance
which could not reasonably be expected to have a material  adverse effect on the
Debtor. No Inventory is evidenced by a negotiable  document of title,  warehouse
receipt  or bill of  lading.  No  non-negotiable  document  of title,  warehouse
receipt or bill of lading has been  issued to any person  other than the Debtor,
and the Debtor has retained possession of all of such non-negotiable  documents,
warehouse receipts and bills of lading. No amount payable under or in connection
with  any  of  the  Collateral  is  evidenced  by  promissory   notes  or  other
instruments.

Section 3.06.  Trade Names.  Schedule 3.6 correctly sets forth any and all trade
names,  division  names,  assumed  names or other  names  under which the Debtor
currently  transacts  business or has transacted  business within the four-month
period prior to the date hereof.

     Section 3.07. Patents and Trademarks. Schedule 3.7 correctly sets forth all
     Patents,  Patent licenses,  Trademarks and Trademark  licenses now owned by
     the Debtor.

ARTICLE IV.

                  The Debtor covenants and agrees that until all obligations and
liabilities in respect of the Obligations  shall have performed and paid in full

collateralized and the Commitments are terminated:

Section 4.01. Perfection of Security Interests. The Debtor will, at its expense,
cause all filings and recordings and other actions  specified on Schedule 4.1 to

with the following:

cause UCC financing statements and continuation statements to be filed and to be
on file in all  applicable  jurisdictions  as required  to perfect the  security
interests  granted to the Agent  hereunder,  to the extent that  applicable  law
permits perfection of a security interest by filing under the UCC;

(ii)  as to all  Proceeds,  it  will  cause  all UCC  financing  statements  and
continuation  statements  filed in accordance with clause (i) above to include a
statement or a checked box  indicating  that Proceeds of all items of Collateral

(iii) as to any amount payable under or in connection with any of the Collateral
which  shall  be or  shall  become  evidenced  by any  promissory  note or other
instrument,  the  Debtor  will  promptly  (but in no event  later  than ten (10)
Business Days after receipt of such note or instrument), pledge and deliver such
note or other  instrument to the Agent as part of the Collateral,  duly endorsed
in a manner reasonably satisfactory to the Agent;

(iv) at the request of the Agent,  the Debtor shall deliver all other Collateral
consisting  of  certificated  securities,  endorsed  for  transfer  in a  manner
reasonably  satisfactory  to the Agent (or  execute  a  securities  intermediary
account  control  agreement  to the  extent  possession  by the  Agent  of  such
securities is not feasible); and

(v) as to all Patents,  Patent licenses,  Trademarks or Trademark licenses,  the
Debtor will effect the recordation or renewal of the recordation of the security
interests of the Agent therein so as to maintain  valid and  perfected  security
interests  therein  under all  applicable  state and federal  laws.  (b) Further
Assurances.  The Debtor  will,  from time to time and at its  expense,  execute,
deliver,  file  or  record  such  UCC  financing  statements,  applications  for
certificates  of title  and such  other  statements,  assignments,  instruments,
documents,  agreements  or other  papers and take any other  action  that may be
necessary or desirable,  or that the Agent may reasonably  request,  in order to
create,  preserve,  perfect,  confirm or validate the  security  interest of the
Agent in the Collateral, to enable the Agent to obtain the full benefits of this
Security  Agreement  or to enable it to exercise  and enforce any of its rights,
powers and remedies hereunder,  including, without limitation, its right to take
possession of the Collateral.

(c) Signature. To the fullest extent permitted by law, the Debtor authorizes the
Agent to sign and file  financing and  continuation  statements  and  amendments
thereto with respect to the Collateral without its signature thereon.

Section 4.03. Change of Name, Identity or Structure.  The Debtor will not change
its name, identity or corporate structure in any manner and, except as set forth
on  Schedule  3.6,  will not conduct its  business  under any trade,  assumed or
fictitious  name unless it shall have given the Agent at least  forty-five  (45)
days'  prior  written  notice  thereof  and shall have taken all action (or made
arrangements to take such action  substantially  simultaneously with such change
if it is  impossible  to take such action in advance)  necessary  or  reasonably
requested  by the  Agent  to  amend  any  financing  statement  or  continuation
statement relating to the security interests granted hereby in order to preserve
such  security  interests  and to  effectuate  or maintain the priority  thereof
against all Persons.

Section 4.04.  Place of Business and Collateral.  The Debtor will not change the
location of (i) its places of business, (ii) its chief executive office or (iii)
the  office or other  locations  where it keeps or holds any  Collateral  or any
records relating thereto from the applicable  location listed on Schedule 3.4 or
3.5 unless,  prior to such change, it notifies the Agent forty-five (45) days in
advance of such change,  makes all UCC filings required by Section 4.2 and takes
all other action necessary or that the Agent may reasonably request to preserve,
perfect,  confirm and protect the security  interests granted hereby. The Debtor
will in no event  change the  location of any  Collateral  if such change  would
cause the security  interest granted hereby in such Collateral to lapse or cease
to be  perfected.  The Debtor  will at all times  maintain  its chief  executive
office within one of the forty-eight contiguous states in which Article 9 of the
uniform commercial code is in effect.

Section  4.05.  Fixtures.  The Debtor will not permit any  Equipment to become a
fixture  unless it shall  have  given the  Agent at least ten (10)  days'  prior
written  notice  thereof and shall have taken all such action and  delivered  or
caused to be delivered to the Agent all  instruments  and documents,  including,
without  limitation,  waivers and subordination  agreements by any landlords and
mortgagees, and filed all financing statements necessary or reasonably requested
by the Agent, to preserve and protect the security  interest  granted herein and
to effectuate or maintain the priority  thereof  against all Persons;  provided,
however,  that,  so long as no Event of  Default or  Potential  Event of Default
shall have  occurred  and be  continuing,  the Debtor  shall not be obligated to
comply with the provisions of this Section 4.5 with respect to the first $50,000
of Equipment (determined based on the then fair market value thereof).

Section 4.06.  Maintenance of Records.  The Debtor will keep and maintain at its
own cost and expense complete books and records relating to the Collateral which
are satisfactory to the Agent  including,  without  limitation,  a record of all
payments received and all credits granted with respect to the Collateral and all
of its other  dealings with the  Collateral.  The Debtor will mark its books and
records pertaining to the Collateral to evidence this Security Agreement and the
security interests granted hereby.  For the Agent' further security,  the Debtor
agrees  that the Agent  shall  have a special  property  interest  in all of the
Debtor's  books and records  pertaining to the  Collateral  and the Debtor shall
deliver  and  turn  over any  such  books  and  records  to the  Agent or to its
representatives at any time on demand of the Agent.

Section  4.07.  Compliance  with Laws The  Debtor  will  comply in all  material
respects with all acts, rules,  regulations,  orders,  decrees and directions of
any government or any state or local government  applicable to the Collateral or
any part  thereof or to the  operation of the  Debtor's  business  except to the
extent that the failure to comply  would not have a material  adverse  effect on
the  financial or other  condition of the Debtor;  provided,  however,  that the
Debtor may contest any act, rule, regulation,  order, decree or direction in any
reasonable  manner which shall not, in the sole opinion of the Agent,  adversely
affect the Agent's  rights or, in the case of  Collateral  located at a facility
identified on Schedule 3.7 hereto,  the first priority of its security  interest
in the Collateral.

Section 4.08. Payment of Taxes. The Debtor will pay promptly when due all taxes,
assessments and governmental charges or levies imposed upon the Collateral or in
respect of its income or  profits  therefrom,  as well as all claims of any kind
(including claims for labor, materials and supplies), except that no such charge
need be paid if (i) the  validity  thereof is being  contested  in good faith by
appropriate  proceedings and (ii) such charge is adequately  reserved against in
accordance  with  generally  accepted  accounting  principles,  as  consistently
applied.

Section 4.09.  Compliance with Terms of Accounts and Contracts.  The Debtor will
perform and comply in all material  respects with all of its  obligations  under
all agreements  relating to the Collateral to which it is a party or by which it
is bound.

Section  4.10.  Limitation on Liens on  Collateral.  The Debtor will not create,
permit or suffer to exist,  and will  defend  the  Collateral  and the  Debtor's
rights with respect  thereto  against and take such other action as is necessary
to  remove  any  Lien,  security  interest,  encumbrance,  or claim in or to the
Collateral other than the security interests created hereunder and such Liens to
the  extent  permitted  pursuant  to  Section  6.2(a)  of the  Revolving  Credit
Agreement.

Section 4.11. Limitations on Modifications of Receivables and Other Intangibles;
No Waivers or Extensions.  The Debtor will not (i) amend,  modify,  terminate or
waive any  provisions  of any material  Receivable  or Other  Intangible  in any
manner which might, when taken together with all such other Receivables or Other
Intangibles,  respectively,  materially  reduce the value of all  Receivables or
Other  Intangibles,  respectively,  in the  Collateral,  (ii)  fail to  exercise
promptly and  diligently  each and every  material right which it may have under
each  Receivable  and Other  Intangible  or (iii) fail to deliver to the Agent a
copy of each material demand,  notice or document received by it relating in any
way to any Receivable or Other Intangible.

Section  4.12.   Maintenance  of  Insurance.   The  Debtor  will  maintain  with
financially   sound  insurance   companies   licensed  to  do  business  in  the
jurisdictions  in which the  Collateral  is located  insurance  policies  on the
Inventory and Equipment in accordance  with the  provisions of Section 6.1(m) of
the Revolving Credit Agreement.

Section 4.13.  Limitations on  Dispositions  of Collateral.  The Debtor will not

the prior  written  consent of the Agent,  sell,  transfer,  lease or  otherwise
dispose of any of the Collateral,  or attempt, offer or contract to do so except

Potential  Event of Default) has occurred and is continuing,  dispositions  in a
commercially reasonable manner of Equipment which has become redundant, worn out
or obsolete or which should be replaced so as to improve  productivity,  so long
as the  proceeds  of any such  disposition  are (x) used to acquire  replacement
equipment  which has comparable or better utility and equivalent or better value
and which is subject to a first priority security interest in favor of the Agent
therein,  except  as  permitted  by  Section  6.2(a)  of  the  Revolving  Credit
Agreement, or (y) applied to repay the Obligations. The inclusion of Proceeds of
the Collateral under the security interests granted hereby shall not be deemed a
consent by the Agent to any sale or disposition of any Collateral  other than as
permitted by this Section 4.13.

Section 4.14. Further  Identification of Collateral.  The Debtor will furnish to
the Agent from time to time  statements and schedules  further  identifying  and
describing  the  Collateral  and  such  other  reports  in  connection  with the

the Agent if the value of the Collateral located at the facilities identified on
Schedule 3.7 hereto is less than 80% of the value of all of the Collateral.

Section  4.15.  Notices.  The  Debtor  will  advise  the Agent  promptly  and in
reasonable detail (i) of any Lien, security interest,  encumbrance or claim made
or  asserted  against  any of the  Collateral,  other  than,  unless  reasonably
requested  by the Agent,  Liens  permitted  by Section  6.2(a) of the  Revolving
Credit  Agreement,  (ii)  of  any  material  change  in the  composition  of the
Collateral,  and (iii) of the  occurrence  of any other event which would have a
material  adverse  effect on the  aggregate  value of the  Collateral  or on the
security interests granted to the Agent in this Security Agreement.

Section 4.16.  Change of Law. The Debtor shall promptly  notify the Agent of any
change in law known to it which (i) adversely  affects or will adversely  affect
the validity,  perfection or priority of the security  interests granted hereby,
(ii)  requires  or will  require a change in the  proceedings  to be followed in
order to maintain and protect such  validity,  perfection  and priority or (iii)
could result in the Agent not having a perfected security interest in any of the
Collateral.

Section 4.17.     Right of Inspection.

(a) Access to Books and Records. The Debtor shall,  following any request by the
Agent and upon reasonable  notice,  permit the Agent or its  representatives  to
have  full  and free  access  during  normal  business  hours to all the  books,
correspondence and records of the Debtor,  and the Agent or its  representatives
may examine the same, take extracts therefrom, make photocopies thereof and have
such discussions with officers,  employees and public  accountants of the Debtor
as the Agent may deem reasonably  necessary,  and the Debtor agrees to render to
the Agent, at the Debtor's cost and expense,  such clerical and other assistance
as  may  be  reasonably  requested  with  regard  thereto.  The  Agent  and  its
representatives  shall upon  reasonable  notice and during normal business hours
also  have the  right to enter  into  and  upon any  premises  where  any of the
Inventory or the  Equipment is located for the purpose of  inspecting  the same,
observing its use or protecting the interests of the Agent therein.

(b)  Audits.  The  Debtor  shall  permit  the  Lenders,   the  Agent  and  their
representatives  and advisors to review the operations of the Debtor and perform
the audits and  examinations  as  provided  in Section  6.1(l) of the  Revolving
Credit Agreement.

     maintain the Equipment in good operating condition,  ordinary wear and tear
     excepted.

Section 4.19.     Covenants Regarding Patent and Trademark Collateral.

(c)  Generally.  At  such  time as the  Debtor  shall  acquire  any  Patents  or
Trademarks,  it will comply with the terms,  covenants  and  warranties  of this
Section 4.19.

(d) Continued Use of Trademark.  The Debtor (either itself or through licensees)
will, unless the Debtor shall reasonably determine,  after consultation with the
Agent,  that a Trademark  is of  negligible  economic  value to the Debtor,  (i)
continue  to use each  Trademark  on each  and  every  Trademark  class of goods
applicable  to its current  products  and  services as  reflected in its current
catalogs,  brochures and price lists in order to maintain each Trademark in full
force and free from any claim of  abandonment  for non-use,  (ii) maintain as in
the past the quality of products  and  services  offered  under each  Trademark,
(iii) employ each Trademark with the appropriate  notice of  registration,  (iv)
not adopt or use any mark which is confusingly  similar to a colorable imitation
of any Trademark and (v) not (and not permit any licensee or sublicensee thereof
to) do any act or knowingly  omit to do any act whereby any Trademark may become
invalidated.

(e) No  Abandonment.  The Debtor will not,  unless the Debtor  shall  reasonably
determine,  after  consultation  with the Agent,  that a Patent is of negligible
economic  value to the  Debtor,  do any act,  or  knowingly  omit to do any act,
whereby any Patent may be abandoned or dedicated.

(f) Notice of Abandonment or Adverse Determinations. The Debtor shall notify the
Agent  immediately if it knows,  or has reason to know,  that any application or
registration  relating  to any  Patent or  Trademark  may  become  abandoned  or
dedicated,  or of any adverse determination or development  (including,  without
limitation,  the institution of, or any such determination or development in any
proceeding  in the United  States  Patent and  Trademark  Office or any court of
tribunal in any  country)  regarding  the  Debtor's  ownership  of any Patent or
Trademark, its right to register the same or keep and maintain the same.

(g) Filings After Notice to Agent.  In no event shall the Debtor,  either itself
or through any agent,  employee,  licensee or designee,  file an application for
registration  of any  Patent or  Trademark  with the  United  States  Patent and
Trademark  Office or any  similar  office or agency in any other  country or any
political  subdivision  thereof,  unless it promptly informs the Agent and, upon
request of the Agent, executes and delivers any and all agreements, instruments,
documents  and papers as the Agent may request to evidence the Agent's  security
interest in such Patent or Trademark and the goodwill and general intangibles of
the  Debtor  relating  thereto or  represented  thereby,  and the Debtor  hereby
constitutes the Agent its attorney-in-fact to execute and file all such writings
for the foregoing purposes, all such acts of such attorney being hereby ratified
and confirmed.

(h) Pursuit of Applications  and Maintenance of  Registrations.  The Debtor will
take all necessary  steps,  including,  without  limitation,  in any  proceeding
before the United States Patent and  Trademark  Office or any similar  office or
agency in any other country or any political  subdivision  thereof,  to maintain
and pursue each  application  (and to obtain the relevant  registration)  and to
maintain each  registration  of the Patents and  Trademarks,  including  without
limitation, filing of applications for renewal, affidavits of use and affidavits
of incontestability;  provided,  however, that no such Patent or Trademark shall
be required to be  maintained  or pursued to the extent such Patent or Trademark
is  determined  by the  Debtor,  after  consultation  with the  Agent,  to be of
negligible economic value to the Debtor.

(i) Notice of  Infringement.  If any of the Patent and  Trademark  Collateral is
infringed,  misappropriated  or  diluted  by a third  party,  the  Debtor  shall
promptly  notify the Agent after it learns thereof and shall,  unless the Debtor
shall reasonably determine,  after consultation with the Agent, that such Patent
and Trademark Collateral is of negligible economic value to the Debtor, promptly
sue for infringement, misappropriation of dilution, seek injunctive relief where
appropriate   and  recover   any  and  all   damages   for  such   infringement,
misappropriation  or  dilution,  or take such other  action as the Debtor  shall
reasonably deem appropriate  under the  circumstances to protect such Patent and
Trademark Collateral.

Section 4.20.  Termination  of Federal  Contracts.  With respect to each Federal
Contract in respect of which the Debtor is required to execute an  Assignment of
Federal  Contract in accordance with Section 4.21 hereof,  the Debtor shall give
prompt written  notice to the Agent if the U.S.  Government  shall  terminate or
threaten to  terminate  (whether  for  convenience  or default) any such Federal
Contract  with the Debtor  having a value  (including  unexercised  options)  of
$100,000 or more. In addition,  the Debtor shall give prompt  written  notice to
the Agent if the U.S.  Government  shall  terminate or threaten to terminate any
contract between the U.S.  Government and any other prime contractor under which
the  Debtor  is a  subcontractor  if the  value of such  subcontract  (including
unexercised  options) is $100,000 or more. Section 4.21. Federal Contracts.  The
Debtor shall  provide to the Agent,  as soon as reasonably  practicable  but not
later than  forty-five  (45) days  following the end of each Fiscal  Quarter,  a
report identifying each Federal Contract to which it is a party, having attached
thereto a copy of the first two pages of such Federal Contract and any amendment
thereto,  to the extent not previously  provided to the Agent. At the request of
the Agent (unless an Event of Default shall have occurred and be continuing,  in
which case no such request  shall be  required),  the Debtor  shall  execute and
deliver to the Agent an Assignment of Federal  Contract,  in  substantially  the
form of Exhibit A hereto (the "Assignment of Federal Contract"), and execute any
other  instruments  or take any other steps  required by the Agent in order that
all moneys due or to become due under such Federal  Contracts  shall be assigned
to the Agent and  notice  thereof  given  under the  Assignment  of Claims  Act,
including without limitation  delivery of Notices of Assignments with respect to
each Federal Contract as contemplated by Appendix A to Exhibit A hereto.

Section 4.22.  Reimbursement  Obligation.  Should the Debtor fail to comply with
the provisions of this Security Agreement, the Revolving Credit Agreement or any
other agreement relating to the Collateral such that the value of any Collateral
or the validity,  perfection,  rank or value of any security interest granted to
the  Agent  hereunder  or  thereunder  is  thereby   diminished  or  potentially
diminished or put at risk (as reasonably  determined by the Agent), the Agent on
behalf of the Debtor may, but shall not be required to,  effect such  compliance
on behalf of the Debtor,  and the Debtor shall  reimburse the Agent for the cost
thereof on demand,  and interest shall accrue on such  reimbursement  obligation
from the date the relevant  costs are incurred  until  reimbursement  thereof in
full at the Default Rate.

ARTICLE V.

                                      REMEDIES; RIGHTS UPON DEFAULT

Section 5.01. UCC Rights.  In the event that any portion of the  Obligations has
been declared or becomes due and payable in accordance with the Revolving Credit
Agreement or other Credit  Documents and such  Obligations have not been paid in
full,  the Agent may in addition to all other rights and remedies  granted to it
in this Security  Agreement and in any other  instrument or agreement  securing,
guarantying,  evidencing or relating to the Obligations, exercise (i) all rights
and  remedies of a secured  party under the UCC (whether or not in effect in the
jurisdiction  where  such  rights  are  exercised)  and  (ii) all  other  rights
available to the Agent at law or in equity.

     Section 5.02.  Payments on Collateral.  Without  limiting the rights of the
     Agent under any other provision of this Security Agreement,  if an Event of
     Default shall occur and be continuing:

(i) all payments  received by the Debtor under or in connection  with any of the
Collateral  shall  be held by the  Debtor  in  trust  for the  Agent,  shall  be
segregated  from other funds of the Debtor and shall  forthwith  upon receipt by
the Debtor be turned  over to the  Agent,  in the same form as  received  by the
Debtor  (duly  indorsed  by the  Debtor  to the  Agent,  if  required  to permit
collection thereof by the Agent); and

(ii) all such  payments  received  by the  Agent  (whether  from the  Debtor  or
otherwise)  may, in the sole  discretion  of the Agent,  be held by the Agent as
collateral  security for, and/or then or at any time thereafter applied in whole
or in part by the Agent to the payment of, the expenses and the  Obligations  as
set forth in Section 5.11 hereof.

Section 5.03.  Possession of Collateral.  In  furtherance of the foregoing,  the
Debtor  expressly  agrees  that,  if an  Event of  Default  shall  occur  and be
continuing, the Agent may (i) by judicial powers, or without judicial process if
it can be done without breach of the peace, enter any premises where any of such
Collateral is or may be located and,  without  charge or liability to the Agent,
seize and remove such  Collateral from such premises and (ii) have access to and
use of the Debtor's books and records relating to such Collateral.

Section 5.04.     Sale of Collateral; Notice.

(a) Sale of Collateral.  The Debtor expressly agrees that if an Event of Default
shall occur and be continuing, the Agent, without demand of performance or other
demand or notice of any kind (except the notice  specified below of the time and
place of any public or private  sale) to or upon the Debtor or any other  Person
(all of which  demands  and/or  notices are hereby  waived by the  Debtor),  may
forthwith (i) apply the cash, if any, then held by it as collateral as specified
in Section  5.11 hereof and (ii) if there shall be no cash or such cash shall be
insufficient to pay the Obligations in full, collect,  receive,  appropriate and
realize upon the Collateral,  and/or sell, assign,  give an option or options to
purchase or otherwise  dispose of and deliver the  Collateral (or contract to do
so) or any part thereof in one or more parcels (which need not be in round lots)
at public or  private  sale,  at any  office of the Agent or  elsewhere  in such
manner as is  commercially  reasonable and, as the Agent may deem best, for cash
or on credit or for future delivery  without  assumption of any credit risk. The
Agent shall have the right upon any such public sale,  and, if the Collateral is
of a type customarily  sold in a recognized  market or is of a type which is the
subject of widely distributed  standard price quotations,  upon any such private
sale or sales,  to purchase the whole or any part of the Collateral so sold, and
thereafter to hold the same,  absolutely and free from any right or claim of any
kind. To the extent  permitted by applicable  law, the Debtor waives all claims,
damages  and  demands  against  the  Agent  arising  out  of  the   foreclosure,
repossession, retention or sale of the Collateral.

(b) Notice of Sale. Unless the Collateral threatens to decline speedily in value
or is of a type  customarily sold on a recognized  market,  the Agent shall give
the Debtor  ten (10)  days'  written  notice of its  intention  to make any such
public or private sale or sale at a broker's board or on a securities  exchange.
Such  notice  shall (i) in the case of a public  sale,  state the time and place
fixed  for  such  sale,  (ii) in the  case of sale at a  broker's  board or on a
securities  exchange,  state the board or  exchange  at which such sale is to be
made and the day on which the  Collateral,  or the portion  thereof  being sold,
will first be offered  for sale and (iii) in the case of a private  sale,  state
the day after which such sale may be consummated.  The Agent shall not obligated
to make any such sale  pursuant  to any such  notice.  The Agent may adjourn any
public or private  sale or cause the same to be  adjourned  from time to time by
announcement at the time and place fixed for the sale, and such sale may be made
at any time or place to which the same may be so  adjourned.  In the case of any
sale of all or any part of the Collateral on credit or for future delivery,  the
Collateral  so sold may be retained by the Agent until the selling price is paid
by the purchaser thereof, but the Agent shall not incur any liability in case of
the failure of such purchase to take up and pay for the  Collateral so sold and,
in the case of such failure, such Collateral may again be sold upon like notice.

(c) Special  Provisions  Relating to Sales of Securities.  The Debtor recognizes
that  the  Agent  may be  unable  to  effect  a  public  sale  of any or all the
Collateral  constituting a "security" (as such term is defined in the Securities
Act) by reason of  certain  prohibitions  contained  in the  Securities  Act and
applicable state securities laws or otherwise, and may be compelled to resort to
one or more private sales thereof to a restricted  group of purchasers that will
be obliged to agree,  among other things,  to acquire such  securities for their
own account for  investment  and not with a view to the  distribution  or resale
thereof.  The Debtor  acknowledges  and agrees  that any such  private  sale may
result in prices and other terms less  favorable than if such sale were a public
sale and, notwithstanding such circumstances,  agrees that any such private sale
shall be deemed to have been made in a commercially reasonable manner. The Agent
shall be under no obligation to delay a sale of any of Collateral constituting a
security  for the  period of time  necessary  to permit  the  issuer  thereof to
register  such  securities  for public sale under the  Securities  Act, or under
applicable state securities laws, even if such issuer would agree to do so.

Section 5.05.  Rights of Purchasers.  Upon any sale of the  Collateral  (whether
public or  private),  the Agent  shall  have the right to  deliver,  assign  and
transfer  to the  purchaser  thereof  the  Collateral  so sold.  Each  purchaser
(including  the  Agent)  at any such  sale  shall  hold the  Collateral  so sold
absolutely,  free from any claim or right of whatever kind, including any equity
or right of redemption of the Debtor who, to the extent permitted by law, hereby
specifically waives all rights of redemption, including, without limitation, any
right to redeem the Collateral  under Section 9-506 of the UCC, and any right to
a judicial or other stay or approval  which it has or may have under any law now
existing or hereafter adopted.

Section 5.06.     Additional Rights of the Agent.

(a) Right to Maintain Proceedings.  The Agent (i) shall have the right and power
to institute and maintain such suits and proceedings as it may deem  appropriate
to protect and enforce the rights  vested in it by this  Security  Agreement and
(ii) may proceed by suit or suits at law or in equity to enforce such rights and
to foreclose  upon the  Collateral and to sell all or, from time to time, any of
the   Collateral   under  the  judgment  or  decree  of  a  court  of  competent
jurisdiction.

(b)  Appointment  of  Receiver.  The Agent  shall,  to the extent  permitted  by
applicable law,  without notice to the Debtor to any party claiming  through the
Debtor,  without regard to the solvency or insolvency at such time of any Person
then liable for the  payment of any of the  Obligations,  without  regard to the
then value of the Collateral and without requiring any bond from any complainant
in such  proceedings,  be entitled as a matter of right to the  appointment of a
receiver  or  receivers  (who may be the  Agent) of the  Collateral  or any part
thereof,  pending  such  proceedings,  with such powers as the court making such
appointment  shall  confer,  and to the  entry  of an order  directing  that the
profits, revenues and other income of the property constituting the whole or any
part of the Collateral be segregated,  sequestered and impounded for the benefit
of the Agent,  and the Debtor  irrevocably  consents to the  appointment of such
receiver or receivers and to the entry of such order.

(c) No Duty to  Exercise  Rights.  In no event  shall the Agent have any duty to
exercise any rights or take any steps to preserve the rights of the Agent in the
Collateral,  nor shall the Agent be liable to the Debtor or any other Person for
any loss caused by the Agent's failure to meet any obligation imposed by Section
9-207 of the UCC or any successor provision. Without limiting the foregoing, the
Agent  shall be deemed to have  exercised  reasonable  care in the  custody  and
preservation  of the  Collateral in its possession if the Collateral is accorded
treatment  substantially equal to that which the Agent accords its own property,
it being understood that the Agent shall not have any duty or responsibility for
(i) ascertaining or taking action with respect to calls, conversions, exchanges,
maturities,  tenders or other matters relative to any Collateral, whether or not
the Agent has or is deemed to have knowledge of such matters, or (ii) taking any
necessary  steps to preserve  rights  against any  parties  with  respect to any
Collateral.

Section 5.07.     Remedies Not Exclusive, etc.

(a) Remedies Not Exclusive. No remedy conferred upon or reserved to the Agent in
this  Security  Agreement  is intended to be  exclusive  of any other  remedy or
remedies,  but every such remedy shall be cumulative and shall be in addition to
every other  remedy  conferred  herein or now or  hereafter  existing at law, in
equity or by statute.

(b)  Restoration  of Rights.  If the Agent shall have  proceeded  to enforce any
right,  remedy or power under this Security Agreement and the proceeding for the
enforcement  thereof shall have been discontinued or abandoned for any reason or
shall have been  determined  adversely  to the  Agent,  the Debtor and the Agent
shall,   subject  to  any  determination  in  such  proceeding,   severally  and
respectively  be  restored  to their  former  positions  and  rights  under this
Security Agreement,  and thereafter all rights, remedies and powers of the Agent
shall continue as though no such proceedings had been taken.

(c)  Enforcement.  All rights of action  under this  Security  Agreement  may be
enforced by the Agent without the  possession of any  instrument  evidencing any
Obligation or the production  thereof at any trial or other proceeding  relative
thereto, and any suit or proceeding  instituted by the Agent shall be brought in
its name and any judgment shall be held as part of the Collateral.

Section 5.08.     Waiver and Estoppel.

(a) No Actions to Impede Sale of Collateral. The Debtor agrees, to the extent it
may lawfully do so, that it will not at any time in any manner  whatsoever claim
or take the benefit or advantage of any appraisal,  valuation,  stay, extension,
moratorium,  turnover or redemption  law, or any law permitting it to direct the
order in which the  Collateral  shall be sold,  now or at any time  hereafter in
force  which  may  delay,   prevent  or  otherwise  affect  the  performance  or
enforcement  of this  Security  Agreement,  and  hereby  waives  all  benefit or
advantage of all such laws. The Debtor covenants that it will not hinder,  delay
or impede  the  execution  of any power  granted  to the Agent in this  Security
Agreement, any Assignment of Federal Contract or any other Credit Document.

(b) Collateral Sold As An Entirety. The Debtor, to the extent it may lawfully do
so, on behalf of itself and all who claim through or under it, including without
limitation any and all  subsequent  creditors,  vendees,  assignees and lienors,
waives  and  releases  all  rights to demand or to have any  marshalling  of the
Collateral upon any sale, whether made under any power of sale granted herein or
pursuant to judicial  proceedings or under any foreclosure or any enforcement of
this Security Agreement,  and consents and agrees that all of the Collateral may
at any such sale be offered and sold as an entirety.

(c) Waiver of  Notices.  The Debtor  waives,  to the  extent  permitted  by law,
presentment,  demand,  protest  and any notice of any kind  (except  the notices
expressly required hereunder) in connection with this Security Agreement and any
action taken by the Agent with respect to the Collateral.

Section 5.09.     Power of Attorney; Powers Coupled With An Interest.

(a) Power of Attorney.  Without limiting any other right granted hereunder,  the
Debtor hereby irrevocably constitutes and appoints the Agent, with full power of
substitution,  as its true and  lawful  attorney-in-fact  with full  irrevocable
power and  authority in the place and stead of the Debtor and in the name of the
Debtor  or in its  own  name,  from  time  to  time  in the  Agent's  reasonable
discretion,  for the  purpose  of  carrying  out  the  terms  of  this  Security
Agreement,  to take any and all  appropriate  action and to execute  any and all
documents and instruments  which may be necessary or desirable to accomplish the
purpose of this Security  Agreement and,  without limiting the generality of the
foregoing,  hereby gives the Agent the power and right, on behalf of the Debtor,
without notice to or assent by the Debtor, to do the following:

     (i)  to  pay  or  discharge  taxes,  liens,  security  interests  or  other
     encumbrances levied or placed on or threatened against the Collateral;

(ii) to effect  any  repairs  or any  insurance  called for by the terms of this
Security  Agreement or any other Credit Document,  and to pay all or any part of
the premiums therefor and the costs thereof;

(iii) upon the occurrence and  continuance of any Event of Default and otherwise
to the  extent  provided  in this  Security  Agreement,  (A) to direct any party
liable for any payment  under any of the  Collateral  to make payment of any and
all moneys due and to come due thereunder  directly to the Agent or as the Agent
shall direct,  (B) to receive  payment of and receipt for, and to demand and sue
for, any and all moneys,  claims and other  amounts due and to become due at any
time in respect of or arising out of the Collateral, (C) to sign and indorse and
receive,  take, assign and deliver, any checks,  notes,  drafts,  negotiable and
non-negotiable  instruments,  any invoices,  freight or express bills,  bills of
lading,  storage or warehouse  receipts,  drafts against  debtors,  assignments,
verifications  and  notices in  connection  with  accounts  and other  documents
relating to the  Collateral,  (D) to  commence,  settle,  compromise,  compound,
prosecute,  defend or adjust any claim,  suit, action or proceeding with respect
to, or in connection  with, the  Collateral,  (E) to sell,  transfer,  assign or
otherwise  deal in or with the  Collateral  or any part  thereof,  as fully  and
effectively  as if the Agent were the absolute  owner  thereof and (F) to do, at
its option,  but at the expense of the Debtor, at any time or from time to time,
all acts and things  which the Agent deems  necessary  to  protect,  preserve or
realize upon the Collateral and the Agent's security interest therein,  in order
to effect the intent of this Security Agreement, all as fully and effectively as
the Debtor might do.

(b) Powers Coupled With an Interest.  All authorizations and agencies granted or
provided  herein with respect to the  Collateral,  including the powers  granted
under clause (a) of this Section 5.9, are irrevocable and powers coupled with an
interest.

Section 5.10. Certain Provisions Relating to Securities.  Solely with respect to
any Collateral  constituting a "security" (as defined in the Securities Act), if
an Event of Default shall have occurred and be continuing,  all such  securities
(as defined in the Securities Act)  constituting a part of the Collateral shall,
at the  request  of the  Agent,  be  registered  in the name of the Agent or its
nominee,  and the Agent or its nominee may  thereafter  exercise (i) all voting,
corporate and other rights,  powers and privileges pertaining to such Collateral
at any meeting of shareholders of the issuer thereof or otherwise,  and (ii) any
and all  rights of  conversion,  exchange,  subscription  and any other  rights,
privileges or options  pertaining to such  Collateral as if it were the absolute
owner  thereof  (including,  without  limitation,  the right to  exchange at its
discretion  any  and  all  such  Collateral  upon  the  merger,   consolidation,
reorganization, recapitalization or other fundamental change in the structure of
any such  issuer,  or upon the exercise by the Debtor or the Agent of any right,
privilege or option pertaining to such Collateral,  and in connection therewith,
the right to deposit and deliver any and all such Collateral with any committee,
depositary, transfer agent, registrar or other designated agency upon such terms
and conditions as it may determine), all without liability except to account for
property  actually  received  by it and except as  provided  in  Section  5.6(c)
hereof,  but the Agent  shall  have no duty to the Debtor to  exercise  any such
right, privilege or option and shall not be responsible for any failure to do so
or delay in so doing.

     Section 5.11.  Application of Monies. The proceeds of any sale of, or other
     realization upon, all or any part of the Collateral shall be applied by the
     Agent in the following order of priority:

                  first,  to  payment  of the  expenses  of such  sale or  other
realization,  including reasonable  compensation to the Agent and its agents and
counsel,  and all  expenses,  liabilities  and advances  incurred or made by the
Agent, its agents and counsel in connection  therewith or in connection with the
care, safekeeping or otherwise of any or all of the Collateral;

     second,  to  payment  of the  Obligations,  in such  order as the Agent may
     elect; and

                  third, any surplus then remaining shall be paid to the Debtor,
or its  successors  or assigns,  or to  whomsoever  may be lawfully  entitled to
receive the same (including  pursuant to Section 9-504(1)(C) of the UCC) or as a
court of competent jurisdiction may direct.

ARTICLE VI.

                                              MISCELLANEOUS

Section 6.01. Notices. All notices, requests and other communications to a party
hereunder  shall be in writing  and shall be given to such party at its  address
set forth on the  signature  page hereof or such other address as such party may
hereafter  specify for that  purpose by notice to the other.  Each such  notice,
request or other  communication shall be effective (i) in the case of telephonic
notice (to the extent  expressly  permitted  hereunder),  when made, (ii) in the
case of notice delivered by overnight  express  courier,  one Business Day after
the Business Day such notice was delivered to such courier, (iii) in the case of
notice  delivered by first class mail, three Business Days after being deposited
in the mail,  postage  prepaid,  return receipt  requested,  (iv) in the case of
notice by hand,  when  delivered,  or (v) in the case of notice by any customary
means of telecommunication, when sent provided confirmation of receipt or answer
back has been  received,  in each  case if  addressed  to any  party  hereto  as
provided  herein.  Rejection or refusal to accept,  or the  inability to deliver
because of a changed address of which no notice was given,  shall not affect the
validity of notice given in accordance with this section.

Section 6.02.  No Waiver;  Cumulative  Remedies.  The Agent shall not by any act
(except by a written  instrument  pursuant  to Section  6.3 hereof) be deemed to
have waived any right or remedy hereunder. No failure to exercise, nor any delay
in exercising,  on the part of the Agent any right, power or privilege hereunder
shall operate as a waiver thereof.  No single or partial  exercise of any right,
power or  privilege  hereunder  shall  preclude  any other or  further  exercise
thereof or the exercise of any other right, power or privilege.  A waiver by the
Agent  of any  right  or  remedy  hereunder  on any one  occasion  shall  not be
construed as a bar to any right or remedy which the Agent would  otherwise  have
on any future occasion.  The rights and remedies herein provided are cumulative,
may be  exercised  singly or  concurrently  and are not  exclusive  of any other
rights or remedies provided by law.

Section 6.03.  Amendments  and Waivers.  None of the terms or provisions of this
Security Agreement may be amended,  supplemented or otherwise modified except by
a written  instrument  executed by the Debtor and the Agent;  provided  that any
provision of this  Security  Agreement may be waived by the Agent in a letter or
agreement  executed by the Agent or by telex or facsimile  transmission from the
Agent.

Section 6.04.  Successors and Assigns. The provisions of this Security Agreement
shall be binding  upon and inure to the benefit of the parties  hereto and their
respective  successors and assigns;  provided,  however, that the Debtor may not
assign or transfer any of its rights or obligations  hereunder without the prior
written consent of the Agent.

     Section 6.05.  Governing Law. THIS SECURITY  AGREEMENT SHALL BE GOVERNED BY
     AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE  COMMONWEALTH OF VIRGINIA,
     OTHER THAN ITS LAWS RESPECTING CHOICE OF LAW OTHER THAN THOSE CONTAINED
IN THE UCC.

Section 6.06.     Limitation by Law; Severability.

(a) All rights,  remedies and powers provided in this Security  Agreement may be
exercised  only to the extent  that the  exercise  thereof  does not violate any
applicable  provision of law, and all the provisions of this Security  Agreement
are intended to be subject to all applicable  mandatory  provisions of law which
may be controlling  and to be limited to the extent  necessary so that they will
not render this Security Agreement  invalid,  unenforceable in whole or in part,
or not entitled to be recorded,  registered or filed upon the  provisions of any
applicable law.

(b) If any provision hereof is invalid and  unenforceable  in any  jurisdiction,
then, to the fullest extent  permitted by law, (i) the other  provisions  hereof
shall  remain  in full  force  and  effect  in such  jurisdiction  and  shall be
liberally  construed in favor of the Agent in order to carry out the  intentions
of the parties  hereto as nearly as may be possible and (ii) the  invalidity  or
unenforceability  of any provision hereof in any  jurisdiction  shall not affect
the validity or enforceability of such provision in any other jurisdiction.

Section  6.07.  Counterparts.  This  Security  Agreement  may be executed in any
number of counterparts and by different parties hereto on separate counterparts,
each complete set of which, when so executed and delivered by all parties, shall
be an original,  but all such counterparts shall together constitute but one and
the same instrument.

Section 6.08. Expenses of the Agent. The Debtor shall pay to the Agent from time
to time upon demand,  all of the costs and expenses incurred by the Agent or any
Lender (including,  without limitation, the reasonable fees and disbursements of
counsel  and any  amounts  payable  by the  Agent or any  Lender to any of their
respective   agents)  (i)  arising  in  connection   with  the   administration,
modification, amendment, waiver or termination of this Security Agreement or any
document or agreement  contemplated hereby or any consent or waiver hereunder or
thereunder  or (ii)  incurred  in  connection  with the  administration  of this
Security  Agreement,  or any document or agreement  contemplated  hereby,  or in
connection  with the  administration,  sale or other  disposition  of Collateral
hereunder  or  under  any  document  or  agreement  contemplated  hereby  or the
preservation,  protection or defense of the rights of the Agent or any Lender in
and to the Collateral.

Section  6.09.  Indemnification.   The  Debtor  shall  at  all  times  hereafter
indemnify, hold harmless and, on demand, reimburse the Agent and the Lenders and
their  respective  subsidiaries,   affiliates,  successors,  assigns,  officers,
directors,   employees  and  agents,  and  their  respective  heirs,  executors,
administrators, successors and assigns (all of the foregoing parties, including,
but not limited to, the Agent, being hereinafter collectively referred to as the
"Indemnities" and individually as an "Indemnitee") from, against and for any and
all liabilities,  obligations,  claims, damages, actions,  penalties,  causes of
action, losses, judgments, suits, costs, expenses and disbursements,  including,
without  limitation,  attorney's  fees  (any  and  all  of the  foregoing  being
hereinafter  collectively referred to as the "Liabilities" and individually as a
"Liability")  which  the  Indemnitees,  or  any  of  them,  might  be or  become
subjected, by reason of, or arising out of the preparation, execution, delivery,
modification,  administration  or enforcement  of, or performance of the Agent's
rights  under,  this  Security  Agreement or any other  document,  instrument or
agreement  contemplated  hereby or executed in  connection  herewith;  provided,
however, that the Debtor shall not be liable to any Indemnitee for any Liability
caused solely by the gross negligence or willful  misconduct of such Indemnitee.
In no event shall any  Indemnitee,  as a condition to enforcing its rights under
this Section 6.9 or  otherwise,  be obligated to make a claim  against any other
Person (including,  without  limitation,  the Agent) to enforce its rights under
this Section 6.9.

Section 6.10.  Termination;  Survival.  This Security  Agreement shall terminate
when the security interests granted hereunder have terminated and the Collateral
has been  released as  provided  in Section  2.6;  provided,  however,  that the
obligations  of the Debtor under Section 4.22 and the provisions of this Article
6 shall survive any such termination.

Section  6.11.  Judicial  Proceedings;   Waiver  of  Jury  Trial.  Any  judicial
proceeding  brought  against  the Debtor  with  respect to any Credit  Agreement
Related  Claim hereby may be brought in any court of competent  jurisdiction  in
the  Commonwealth  of Virginia,  County of Fairfax,  or any Federal court in the
Eastern  District of Virginia,  and, by execution  and delivery of this Security
Agreement,   the  Debtor  (a)  accepts,   generally  and  unconditionally,   the
nonexclusive  jurisdiction  of such courts and any related  appellate  court and
irrevocably  agrees to be bound by any judgment  rendered  thereby in connection
with any Credit Agreement Related Claim and (b) irrevocably waives any objection
it may now or hereafter have as to the venue of any such  proceeding  brought in
such a court or that such a court is an  inconvenient  forum.  The Debtor hereby
waives personal  service of process and consents that service of process upon it
may be made by certified or registered mail,  return receipt  requested,  at its
address specified or determined in accordance with the provisions of Section 6.1
hereof,  and service so made shall be deemed completed on the earlier of (x) the
receipt  thereof and (y) if sent by registered or certified mail (return receipt
requested),  the fifth (5th) Business Day after such service is deposited in the
mail. Nothing herein shall affect the right of the Agent to serve process in any
other  manner  permitted  by law or shall  limit the right of the Agent to bring
proceedings  against  the  Debtor in the courts of any other  jurisdiction.  Any
judicial proceeding by the Debtor against the Agent relating to or involving any
Credit  Agreement  Related Claim hereby shall be brought only in a court located
in the Commonwealth of Virginia,  County of Fairfax, or the Federal court in the
Eastern  District of Virginia.  THE DEBTOR AND THE AGENT HEREBY  UNCONDITIONALLY
WAIVE  TRIAL  BY JURY IN ANY  JUDICIAL  PROCEEDING  TO WHICH  THEY  ARE  PARTIES
INVOLVING ANY CREDIT AGREEMENT RELATED CLAIM.

Section  6.12.  Integration.  This  Security  Agreement  and  the  other  Credit
Documents  constitute  the entire  agreement  of the  Agent,  the  Lenders,  the
Borrower and the other Credit  Parties with respect to the subject matter hereof
and  thereof,  and  there  are no  promises,  undertakings,  representations  or
warranties by the Agent or any Lender  relative to the subject  matter hereof or
thereof not  expressly  set forth or  referred to herein or in the other  Credit
Documents.

Section 6.13.  Authority of Agent. The Debtor  acknowledges  that the rights and
responsibilities  of the Agent under this Security Agreement with respect to any
action  taken by the Agent or the exercise or  non-exercise  by the Agent of any
option,  voting right,  request,  judgment or other right or remedy provided for
herein or resulting or arising out of this Security  Agreement shall, as between
the Agent and the Lenders,  be governed by the Revolving Credit Agreement and by
such other  agreements with respect thereto as may exist from time to time among
them, but, as between the Agent and the Debtor,  the Agent shall be conclusively
presumed to be acting as agent for the Lenders with full and valid  authority so
to act or refrain from acting, and the Debtor shall not be under any obligation,
or entitlement, to make any inquiry respecting such authority.

Section 6.14. Headings,  Bold Type and Table of Contents.  The section headings,
subsection headings,  and bold type used herein and the Table of Contents hereto
have been  inserted  for  convenience  of reference  only and do not  constitute

         1. Incorporation By Reference. The provisions of the Security Agreement
are  incorporated  herein by  reference,  and the terms  defined in the Security
Agreement are used herein with the same meanings.

         2.  Representations.  The Assignor represents and warrants to the Agent
that (a) the Contract is legal,  valid and binding on the  Assignor  and, to its
knowledge,  the other parties thereto,  is in full force and effect,  and is not
evidenced  by any  chattel  paper or  instrument,  (b) upon due  filing  of this
Agreement,  together  with a Notice of Assignment  substantially  in the form of
Appendix A hereto with the authorized representative, the execution and delivery
of this Agreement does not violate and is not in conflict with the provisions of
the  Contract,  (c) there has been no default on the part of the Assignor or any

statements in favor of the Agent,  (f) no set-off or  counterclaim to any moneys

         3. Collateral. As security and collateral for the payment of all of the

compliance  with,  by the  Assignor,  all of the terms,  covenants,  conditions,
stipulations,  and  agreements  contained in this  Agreement and in the Security
Agreement,  the Assignor hereby assigns to the Agent,  and grants to the Agent a
lien on and  security  interest  in,  all  moneys  and claims for moneys now and
hereafter  due and to  become  due to the  Assignor  under or by  reason  of the
Contract,  together  with all  cash and  non-cash  proceeds  thereof;  provided,

the Assignor covenants as follows:

(c) The  Assignor  shall  place  on any and all  vouchers,  invoices,  or  other
instruments demanding payment under the Contract the direction that such payment
is to be made to the Agent in accordance with Section 5 of this Agreement.

(d) The Assignor shall promptly upon request execute,  acknowledge,  and deliver
any  notice,  financing  statement,   renewal,   affidavit,   deed,  assignment,
continuation statement,  security agreement,  certificate,  or other document as

termination  or  cancellation  of  the  Contract  is  made  or  effected  by the
Government,  the Assignor  will  promptly  notify the Agent thereof and promptly
furnish to the Agent a copy of any  document or  agreement  evidencing  any such

rendered by the Assignor under or in connection with the Contract.

(g) The  Assignor  will at all times  keep  accurate  and  complete  records  of
performance  by the Assignor  under the  Contract,  and the Agent and its agents
shall have the right,  during normal business hours and upon reasonable  advance
notice,  to call at the place or places of business of the Assignor at intervals
to be  determined  by the Agent,  and without  hindrance  or delay,  to inspect,
audit,  check,  and make extracts  from the books,  records,  journals,  orders,
receipts,  correspondence,  and other data  relating  to the  Contract or to any
other transactions between the parties hereto related to the Contract.

         5. Payments. The Assignor hereby authorizes,  empowers, and directs the
Government to draw all checks,  drafts,  or other  instruments  representing the
payments of money due the Assignor under the Contract  (herein called the "Items

deliver such  instruments or checks to the order of the Agent. The Assignor does
hereby  irrevocably  (subject  to  revocation  with the  consent  of the  Agent)
designate and appoint (which appointment is coupled with an interest) the Agent,
and the Agent's  successors in interest by operation of law, the Assignor's true
and  lawful  attorney  with  power  irrevocable  for  the  Assignor  and  in the
Assignor's  name,  place,  and  stead,  but at the sole cost and  expense of the
Assignor,  to receive,  endorse,  and collect all Items of Payment,  and to ask,
demand,  receive,  receipt,  and give acquittances for any and all amounts which
may be payable  or which  become due and  payable  by the  Government  under the
Contract,  and in the Agent's  discretion to file any claim or to take any other
action  or  proceeding,  either  in the  Agent's  own name or in the name of the
Assignor or otherwise,  which to the Agent or any successor in interest  thereof
may seem  necessary  or  desirable in order to collect or endorse the payment of
any and all amounts now due or owing or which may  hereafter be or become due or

                                            SECURITY INTERESTS

Section  2.01.  Grant of  Security  Interests.  To secure  the due and  punctual
payment of all Obligations,  howsoever  created,  arising or evidenced,  whether
direct or indirect,  absolute or contingent, now or hereafter existing or due or
to become  due,  whether at  maturity  or upon  acceleration  or  otherwise,  in
accordance with the terms thereof and to secure the due and punctual performance
of all of the  Obligations  and in order to induce the Agent and the  Lenders to
enter into the Revolving  Credit Agreement and the other Credit  Documents,  the
Debtor hereby pledges,  assigns,  delivers,  conveys and transfers to the Agent,
for the ratable benefit of the Lenders, and grants to the Agent, for the ratable
benefit of the Lenders, a first priority and continuing security interest in and
lien on, all of the  Debtor's  right,  title and  interest  in, to and under the
following, whether now existing or hereafter acquired (the "Collateral"):

(i)      all Receivables;

(ii)     all Other Intangibles;

(iii)    all Equipment;

(iv)     all Inventory;

(v) to the  extent  not  included  in the  foregoing,  all  securities  (whether
certificated or uncertificated)  and all financial assets,  whether now existing
or hereafter arising, including, without limitation, all capital stock issued by
any Person and held by Debtor,  and all  partnership  interests,  whether in the
nature of a joint venture,  limited liability company member's interest,  master
limited partnership, teaming arrangement or otherwise;

(vi) to the extent not included in the foregoing,  all other personal  property,
whether  tangible or intangible,  and wherever located whether within or outside
of the United  States,  including,  but not  limited  to,  the  balance of every
deposit  account now or hereafter  existing of the Debtor with any bank or other
financial  institution and all monies of the Debtor and all rights to payment of
money of the Debtor;

(vii) to the extent not  included  in the  foregoing,  all  books,  ledgers  and
records and all computer  programs,  tapes,  discs, punch cards, data processing
software,  transaction  files,  master  files and  related  property  and rights
(including computer and peripheral equipment) necessary or helpful in enforcing,
identifying or establishing any item of Collateral; and

(viii) to the extent not otherwise included, all Proceeds and products of any or
all of the foregoing, whether existing on the date hereof or arising hereafter;

provided,  however,  notwithstanding  anything to the contrary contained herein,
the  Debtor is not  assigning,  pledging  or  otherwise  encumbering  under this
Security Agreement its interests in any Federal Contract to which it is a party,
or in accounts or receivables due to Debtor under such Federal Contract,  to the
extent,  but only to the extent,  such assignment,  pledge or other  encumbrance
would  breach or violate or would cause Debtor to breach or violate such Federal
Contract or statutes or regulations applicable thereto, it being understood that
this proviso does not apply to, or in any way limit, Debtor's assignment, pledge
or encumbrance of Proceeds of all Federal Contracts to which it is a party.

Section  2.02.  Continuing  Liability  of the  Debtor.  Anything  herein  to the
contrary notwithstanding,  the Debtor shall remain liable to observe and perform
all the  terms and  conditions  to be  observed  and  performed  by it under any
contract,   agreement,   warranty  or  other  obligation  with  respect  to  the
Collateral;  and  shall do  nothing  to impair  the  security  interests  herein
granted.  The Agent shall not have any  obligation  or liability  under any such
contract,  agreement, warranty or obligation by reason of or arising out of this
Security  Agreement  or the receipt by the Agent of any payment  relating to any
Collateral,  nor shall the Agent be  required  to perform or fulfill  any of the
obligations of the Debtor with respect to the Collateral, to make any inquiry as
to the nature or sufficiency of any payment received by it or the sufficiency of
the  performance  of any party's  obligations  with  respect to any  Collateral.
Furthermore,  the  Agent  shall not be  required  to file any claim or demand to
collect any amount due or to enforce the performance of any party's  obligations
with respect to, the Collateral.

Section 2.03.     Sales and Collections.

(a) Sales of  Inventory  in the  Ordinary  Course  of  Business.  The  Debtor is
authorized (i) to sell in the ordinary course of its business for fair value and
on an  arm's-length  basis  any of its  Inventory  normally  held by it for such
purpose and (ii) to use and consume, in the ordinary course of its business, any
raw materials,  supplies and materials normally held by it for such purpose. The
Agent may, upon the occurrence of any Event of Default, without cause or notice,
curtail or terminate such authority at any time.

(b) Collection of Receivables. The Debtor is authorized to collect amounts owing
to it with respect to the Collateral, except as otherwise provided in connection
with the Assignment of Federal Contract, if any as provided herein. However, the
Agent may, upon and during the continuance of an Event of Default or a Potential
Event of Default, notify Account Debtors obligated to make payments under any or
all Receivables or Other  Intangibles that the Agent has a security  interest in
such Collateral and that payments shall be made directly to the Agent.  Upon the
request of the Agent upon and during the continuance of an Event of Default or a
Potential  Event of Default,  as the case may be, the Debtor will so notify such
Account  Debtors  and  will  execute  such  contract  assignments,   notices  of
assignment or other  documents as may be required by such Account  Debtors.  The
Debtor will use all  reasonable  efforts to cause each Account  Debtor to comply
with the foregoing  instruction.  In furtherance  of the  foregoing,  the Debtor
authorizes the Agent upon and during the continuance of an Event of Default or a
Potential  Event of Default (i) to ask for,  demand,  collect,  receive and give
acquittances  and  receipts  for any and all amounts due and to become due under
any Collateral and in the name of the Debtor or its own name or otherwise,  (ii)
to  take  possession  of,  endorse  and  collect  any  checks,   drafts,  notes,
acceptances  or other  instruments  for the  payment  of  monies  due  under any
Collateral  and (iii) to file any claim or take any other action in any court of
law or equity or  otherwise  which it may deem  appropriate  for the  purpose of
collecting  any  amounts  due under any  Collateral.  The  Agent  shall  have no
obligation  to obtain or record any  information  relating to the source of such
funds or the obligations in respect of which payments have been made.

Section 2.04.     Segregation of Proceeds.

(a) Cash Collateral  Account  Maintained by Agent. Upon an Event of Default or a
Potential  Event of  Default,  the Agent shall have the right at any time during
the  continuance  thereof to cause to be opened and  maintained at the office of
the Agent in McLean,  Virginia a  non-interest  bearing  bank account (the "Cash
Collateral  Account") which will contain only Proceeds.  Any "cash proceeds" (as
such term is defined  in  Section  9-306(1)  of the UCC)  received  by the Agent
directly from Account  Debtors  obligated to make payments under  Receivables or
Other Intangibles  pursuant to Section 2.3 hereof or from the Debtor pursuant to
clause (b) of this Section 2.4,  whether  consisting of checks,  notes,  drafts,
bills of exchange, money orders,  commercial paper or other Proceeds received on
account of any  Collateral,  shall be promptly  deposited in the Cash Collateral
Account, and until so deposited shall be held in trust for the Agent as property
of the  Agent  and shall not be  commingled  with any  funds of the  Debtor  not
constituting  Proceeds  of  Collateral.  The name in which  the Cash  Collateral
Account is carried shall clearly  indicate that the funds deposited  therein are
the  property  of the  Debtor,  subject to the  security  interest  of the Agent
hereunder. Such Proceeds, when deposited,  shall continue to be security for the
Obligations   and  shall  not  constitute   payment  thereof  until  applied  as
hereinafter  provided.  The Agent shall have sole  dominion and control over the
funds deposited in the Cash Collateral Account,  and such funds may be withdrawn
therefrom only by the Agent.

(b) Deposit of  Proceeds  by the Debtor.  Upon notice by the Agent to the Debtor
that the Cash  Collateral  Account has been  opened,  the Debtor shall cause all
cash  Proceeds  collected  by it to be  delivered  to the Agent  forthwith  upon
receipt,  in the original  form in which  received  (with such  endorsements  or
assignments as may be necessary to permit collection  thereof by the Agent), and
for such  purpose the Debtor  hereby  irrevocably  authorizes  and  empowers the
Agent,  its officers,  employees and  authorized  agents to endorse and sign the
name of the Debtor on all checks, drafts, money orders or other media of payment
so delivered,  and such endorsements or assignments shall, for all purposes,  be
deemed to have been made by the Debtor prior to any  endorsement  or  assignment
thereof by the Agent.  The Agent may use any  convenient or customary  means for
the purpose of collecting  such checks,  drafts,  money orders or other media of
payment.

Section 2.05.  Verification  of  Receivables.  The Agent shall have the right to
make test  verifications of Receivables in any reasonable manner and through any
medium that it considers  advisable,  and the Debtor  agrees to furnish all such
assistance and  information  as the Agent may  reasonable  require in connection
therewith.  The Debtor at its expense will cause its chief financial  officer to
furnish to the Agent at any reasonable  time and from time to time promptly upon
the Agent's reasonable request,  the following reports:  (i) a reconciliation of
all Receivables, (ii) an aging of all Receivables, (iii) trial balances and (iv)
a test verification of such Receivables as the Agent may request.

Section 2.06.     Release of Collateral.

(a) Security  Interest of Agent Ceases Upon Permitted  Dispositions.  The Debtor
may sell or realize upon or transfer or otherwise  dispose of Collateral only to
the extent permitted by Section 4.13, and the security interests of the Agent in
such  Collateral so sold,  realized upon or disposed of (but not in the Proceeds
arising from such sale, realization or disposition) shall cease immediately upon
such sale, realization or disposition, without any further action on the part of
the Agent.  The Agent,  if requested in writing by the Debtor but at the expense
of the Debtor,  is hereby  authorized  and  instructed to deliver to the Account
Debtor or the purchaser or other transferee of any such Collateral a certificate
stating  that the Agent no longer  has a  security  interest  therein,  and such
Account Debtor or such purchaser or other  transferee  shall be entitled to rely
conclusively on such certificate for any and all purposes.

(b) Filing of  Termination  Statements.  Upon the  payment in full of all of the
Obligations  and if  there  is no  commitment  by any  Lender  to  make  further
advances,  incur obligations or otherwise give value, the Agent will (as soon as
reasonably  practicable  after receipt of notice from the Debtor  requesting the
same but at the  expense  of the  Debtor)  deliver  to the  Debtor  (i) for each
jurisdiction  in  which a UCC  financing  statement  is on file to  perfect  the
security  interests  granted to the Agent  hereunder,  a  termination  statement
(appropriately  completed)  to the  effect  that the  Agent no  longer  claims a
security interest under such financing statement,  and (ii) such other documents
as  the  Debtor  shall  reasonably  request   evidencing   satisfaction  of  the
Obligations  and the  release  of the  security  interests  granted to the Agent
hereunder.

ARTICLE III.

                                      REPRESENTATIONS AND WARRANTIES

         The Debtor represents and warrants that:

Section 3.01. Title to Collateral.  Except for the security interests granted to
the Agent  pursuant to this  Security  Agreement  and as otherwise  permitted by
Section 6.2(a) of the Revolving Credit  Agreement,  the Debtor is the sole owner
of each item of the Collateral,  having good and marketable title thereto,  free
and clear of any and all Liens.

Section 3.02.     Validity, Perfection and Priority of Security Interests.

(a) By complying  with Section 4.1 hereof,  the Debtor will have created a valid
security  interest in favor of the Agent in all existing  Collateral  and in all
identifiable  Proceeds of such  Collateral,  which security  interest (except in
respect of  Collateral  not located at a facility  identified  on  Schedule  3.7
hereto  and motor  vehicles  for  which the  exclusive  manner of  perfecting  a
security interest therein is by noting such security interest in the certificate
of title in accordance with local law) would be prior to the claims of a trustee
in bankruptcy under Section 544(a) of the Bankruptcy Code. Continuing compliance
by the Debtor  with the  provisions  of Section  4.2 hereof will also (i) create
valid security interests in all Collateral acquired after the date hereof and in
all  identifiable  Proceeds  of such  Collateral  and (ii) cause  such  security
interests in all Collateral and in all Proceeds which are (A) identifiable  cash
Proceeds of  Collateral  covered by  financing  statements  required to be filed
hereunder,  (B)  identifiable  Proceeds  in  which a  security  interest  may be
perfected  by such  filing  under  the UCC and  (C)  any  Proceeds  in the  Cash
Collateral Account to be duly perfected under the UCC, in each case prior to the
claims of a trustee in bankruptcy  under the Bankruptcy  Code (except in respect
of Collateral not located at a facility identified on Schedule 3.5 hereto).

(b) The  security  interests  of the  Agent  in the  Collateral  located  at the
facilities identified on Schedule 3.5 hereto rank first in priority.  Other than
financing   statements  or  other  similar  documents  perfecting  the  security
interests  in favor of the  Agent,  no  financing  statements,  deeds of  trust,
mortgages or similar documents covering all or any part of the Collateral are on
file or of record in any  government  office in any  jurisdiction  in which such
filing or recording  would be  effective to perfect a security  interest in such
Collateral,  nor is any of the Collateral in the possession of any Person (other
than the Debtor) asserting any claim thereto or security interest therein.

Section 3.03.  Enforceability of Receivables and Other Intangibles.  To the best
knowledge of the Debtor,  each  Receivable  and Other  Intangible is a valid and
binding obligation of the related Account Debtor in respect thereof, enforceable
in accordance with its terms,  except as such  enforceability  may be limited by
applicable bankruptcy,  insolvency,  reorganization,  moratorium or similar laws
affecting  the  enforcement  of  creditors'  rights  generally  and  by  general
provisions of equity (regardless of whether such enforceability is considered in
a  proceeding  in equity or at law),  and  complies  with any  applicable  legal
requirements.

Section 3.04.  Place of Business.  Schedule 3.4  correctly  sets forth the chief
executive  office and principal  place of business of the Debtor and the offices
of the Debtor where records  concerning  Receivables  and Other  Intangibles are
kept.

Section 3.05.  Location of  Collateral.  Schedule 3.5  correctly  sets forth the
location of all Equipment and Inventory,  other than rolling stock, aircraft and
goods in transit.  Except as otherwise  specified in Schedule 3.5, all Inventory
and Equipment  has been located at the address  specified on Schedule 3.5 at all
times during the  four-month  period prior to the date hereof while owned by the
Debtor.  All Inventory has been and will be produced in compliance with the Fair
Labor Standards Act, 29 U.S.C.  ss.ss.  201-219,  except for such non-compliance
which could not reasonably be expected to have a material  adverse effect on the
Debtor. No Inventory is evidenced by a negotiable  document of title,  warehouse
receipt  or bill of  lading.  No  non-negotiable  document  of title,  warehouse
receipt or bill of lading has been  issued to any person  other than the Debtor,
and the Debtor has retained possession of all of such non-negotiable  documents,
warehouse receipts and bills of lading. No amount payable under or in connection
with  any  of  the  Collateral  is  evidenced  by  promissory   notes  or  other
instruments.

Section 3.06.  Trade Names.  Schedule 3.6 correctly sets forth any and all trade
names,  division  names,  assumed  names or other  names  under which the Debtor
currently  transacts  business or has transacted  business within the four-month
period prior to the date hereof.

     Section 3.07. Patents and Trademarks. Schedule 3.7 correctly sets forth all
     Patents,  Patent licenses,  Trademarks and Trademark  licenses now owned by
     the Debtor.

ARTICLE IV.

                                                COVENANTS

                  The Debtor covenants and agrees that until all obligations and
liabilities in respect of the Obligations  shall have performed and paid in full
and  until  no  Standby   Letters  of  Credit  are  outstanding  or  fully  cash
collateralized and the Commitments are terminated:

Section 4.01. Perfection of Security Interests. The Debtor will, at its expense,
cause all filings and recordings and other actions  specified on Schedule 4.1 to
have been completed on or prior to the Effective Date.

Section 4.02.     Further Actions.

(a) At all times after the date hereof, the Debtor will, at its expense,  comply
with the following:

(i) as to all Receivables,  Other Intangibles,  Equipment and Inventory, it will
cause UCC financing statements and continuation statements to be filed and to be
on file in all  applicable  jurisdictions  as required  to perfect the  security
interests  granted to the Agent  hereunder,  to the extent that  applicable  law
permits perfection of a security interest by filing under the UCC;

(ii)  as to all  Proceeds,  it  will  cause  all UCC  financing  statements  and
continuation  statements  filed in accordance with clause (i) above to include a
statement or a checked box  indicating  that Proceeds of all items of Collateral
described herein are covered;

(iii) as to any amount payable under or in connection with any of the Collateral
which  shall  be or  shall  become  evidenced  by any  promissory  note or other
instrument,  the  Debtor  will  promptly  (but in no event  later  than ten (10)
Business Days after receipt of such note or instrument), pledge and deliver such
note or other  instrument to the Agent as part of the Collateral,  duly endorsed
in a manner reasonably satisfactory to the Agent;

(iv) at the request of the Agent,  the Debtor shall deliver all other Collateral
consisting  of  certificated  securities,  endorsed  for  transfer  in a  manner
reasonably  satisfactory  to the Agent (or  execute  a  securities  intermediary
account  control  agreement  to the  extent  possession  by the  Agent  of  such
securities is not feasible); and

(v) as to all Patents,  Patent licenses,  Trademarks or Trademark licenses,  the
Debtor will effect the recordation or renewal of the recordation of the security
interests of the Agent therein so as to maintain  valid and  perfected  security
interests  therein  under all  applicable  state and federal  laws.  (b) Further
Assurances.  The Debtor  will,  from time to time and at its  expense,  execute,
deliver,  file  or  record  such  UCC  financing  statements,  applications  for
certificates  of title  and such  other  statements,  assignments,  instruments,
documents,  agreements  or other  papers and take any other  action  that may be
necessary or desirable,  or that the Agent may reasonably  request,  in order to
create,  preserve,  perfect,  confirm or validate the  security  interest of the
Agent in the Collateral, to enable the Agent to obtain the full benefits of this
Security  Agreement  or to enable it to exercise  and enforce any of its rights,
powers and remedies hereunder,  including, without limitation, its right to take
possession of the Collateral.

(c) Signature. To the fullest extent permitted by law, the Debtor authorizes the
Agent to sign and file  financing and  continuation  statements  and  amendments
thereto with respect to the Collateral without its signature thereon.

Section 4.03. Change of Name, Identity or Structure.  The Debtor will not change
its name, identity or corporate structure in any manner and, except as set forth
on  Schedule  3.6,  will not conduct its  business  under any trade,  assumed or
fictitious  name unless it shall have given the Agent at least  forty-five  (45)
days'  prior  written  notice  thereof  and shall have taken all action (or made
arrangements to take such action  substantially  simultaneously with such change
if it is  impossible  to take such action in advance)  necessary  or  reasonably
requested  by the  Agent  to  amend  any  financing  statement  or  continuation
statement relating to the security interests granted hereby in order to preserve
such  security  interests  and to  effectuate  or maintain the priority  thereof
against all Persons.

Section 4.04.  Place of Business and Collateral.  The Debtor will not change the
location of (i) its places of business, (ii) its chief executive office or (iii)
the  office or other  locations  where it keeps or holds any  Collateral  or any
records relating thereto from the applicable  location listed on Schedule 3.4 or
3.5 unless,  prior to such change, it notifies the Agent forty-five (45) days in
advance of such change,  makes all UCC filings required by Section 4.2 and takes
all other action necessary or that the Agent may reasonably request to preserve,
perfect,  confirm and protect the security  interests granted hereby. The Debtor
will in no event  change the  location of any  Collateral  if such change  would
cause the security  interest granted hereby in such Collateral to lapse or cease
to be  perfected.  The Debtor  will at all times  maintain  its chief  executive
office within one of the forty-eight contiguous states in which Article 9 of the
uniform commercial code is in effect.

Section  4.05.  Fixtures.  The Debtor will not permit any  Equipment to become a
fixture  unless it shall  have  given the  Agent at least ten (10)  days'  prior
written  notice  thereof and shall have taken all such action and  delivered  or
caused to be delivered to the Agent all  instruments  and documents,  including,
without  limitation,  waivers and subordination  agreements by any landlords and
mortgagees, and filed all financing statements necessary or reasonably requested
by the Agent, to preserve and protect the security  interest  granted herein and
to effectuate or maintain the priority  thereof  against all Persons;  provided,
however,  that,  so long as no Event of  Default or  Potential  Event of Default
shall have  occurred  and be  continuing,  the Debtor  shall not be obligated to
comply with the provisions of this Section 4.5 with respect to the first $50,000
of Equipment (determined based on the then fair market value thereof).

Section 4.06.  Maintenance of Records.  The Debtor will keep and maintain at its
own cost and expense complete books and records relating to the Collateral which
are satisfactory to the Agent  including,  without  limitation,  a record of all
payments received and all credits granted with respect to the Collateral and all
of its other  dealings with the  Collateral.  The Debtor will mark its books and
records pertaining to the Collateral to evidence this Security Agreement and the
security interests granted hereby.  For the Agent' further security,  the Debtor
agrees  that the Agent  shall  have a special  property  interest  in all of the
Debtor's  books and records  pertaining to the  Collateral  and the Debtor shall
deliver  and  turn  over any  such  books  and  records  to the  Agent or to its
representatives at any time on demand of the Agent.

Section  4.07.  Compliance  with Laws The  Debtor  will  comply in all  material
respects with all acts, rules,  regulations,  orders,  decrees and directions of
any government or any state or local government  applicable to the Collateral or
any part  thereof or to the  operation of the  Debtor's  business  except to the
extent that the failure to comply  would not have a material  adverse  effect on
the  financial or other  condition of the Debtor;  provided,  however,  that the
Debtor may contest any act, rule, regulation,  order, decree or direction in any
reasonable  manner which shall not, in the sole opinion of the Agent,  adversely
affect the Agent's  rights or, in the case of  Collateral  located at a facility
identified on Schedule 3.7 hereto,  the first priority of its security  interest
in the Collateral.

Section 4.08. Payment of Taxes. The Debtor will pay promptly when due all taxes,
assessments and governmental charges or levies imposed upon the Collateral or in
respect of its income or  profits  therefrom,  as well as all claims of any kind
(including claims for labor, materials and supplies), except that no such charge
need be paid if (i) the  validity  thereof is being  contested  in good faith by
appropriate  proceedings and (ii) such charge is adequately  reserved against in
accordance  with  generally  accepted  accounting  principles,  as  consistently
applied.

Section 4.09.  Compliance with Terms of Accounts and Contracts.  The Debtor will
perform and comply in all material  respects with all of its  obligations  under
all agreements  relating to the Collateral to which it is a party or by which it
is bound.

Section  4.10.  Limitation on Liens on  Collateral.  The Debtor will not create,
permit or suffer to exist,  and will  defend  the  Collateral  and the  Debtor's
rights with respect  thereto  against and take such other action as is necessary
to  remove  any  Lien,  security  interest,  encumbrance,  or claim in or to the
Collateral other than the security interests created hereunder and such Liens to
the  extent  permitted  pursuant  to  Section  6.2(a)  of the  Revolving  Credit
Agreement.

Section 4.11. Limitations on Modifications of Receivables and Other Intangibles;
No Waivers or Extensions.  The Debtor will not (i) amend,  modify,  terminate or
waive any  provisions  of any material  Receivable  or Other  Intangible  in any
manner which might, when taken together with all such other Receivables or Other
Intangibles,  respectively,  materially  reduce the value of all  Receivables or
Other  Intangibles,  respectively,  in the  Collateral,  (ii)  fail to  exercise
promptly and  diligently  each and every  material right which it may have under
each  Receivable  and Other  Intangible  or (iii) fail to deliver to the Agent a
copy of each material demand,  notice or document received by it relating in any
way to any Receivable or Other Intangible.

Section  4.12.   Maintenance  of  Insurance.   The  Debtor  will  maintain  with
financially   sound  insurance   companies   licensed  to  do  business  in  the
jurisdictions  in which the  Collateral  is located  insurance  policies  on the
Inventory and Equipment in accordance  with the  provisions of Section 6.1(m) of
the Revolving Credit Agreement.

Section 4.13.  Limitations on  Dispositions  of Collateral.  The Debtor will not
directly or indirectly (through the sale of stock, merger or otherwise), without
the prior  written  consent of the Agent,  sell,  transfer,  lease or  otherwise
dispose of any of the Collateral,  or attempt, offer or contract to do so except
for (i) sales of Inventory in the ordinary course of its business for fair value
in  arm's-length  transactions  and  (ii) so long as no  Event  of  Default  (or
Potential  Event of Default) has occurred and is continuing,  dispositions  in a
commercially reasonable manner of Equipment which has become redundant, worn out
or obsolete or which should be replaced so as to improve  productivity,  so long
as the  proceeds  of any such  disposition  are (x) used to acquire  replacement
equipment  which has comparable or better utility and equivalent or better value
and which is subject to a first priority security interest in favor of the Agent
therein,  except  as  permitted  by  Section  6.2(a)  of  the  Revolving  Credit
Agreement, or (y) applied to repay the Obligations. The inclusion of Proceeds of
the Collateral under the security interests granted hereby shall not be deemed a
consent by the Agent to any sale or disposition of any Collateral  other than as
permitted by this Section 4.13.

Section 4.14. Further  Identification of Collateral.  The Debtor will furnish to
the Agent from time to time  statements and schedules  further  identifying  and
describing  the  Collateral  and  such  other  reports  in  connection  with the
Collateral as the Agent may reasonably request. The Debtor shall promptly notify
the Agent if the value of the Collateral located at the facilities identified on
Schedule 3.7 hereto is less than 80% of the value of all of the Collateral.

Section  4.15.  Notices.  The  Debtor  will  advise  the Agent  promptly  and in
reasonable detail (i) of any Lien, security interest,  encumbrance or claim made
or  asserted  against  any of the  Collateral,  other  than,  unless  reasonably
requested  by the Agent,  Liens  permitted  by Section  6.2(a) of the  Revolving
Credit  Agreement,  (ii)  of  any  material  change  in the  composition  of the
Collateral,  and (iii) of the  occurrence  of any other event which would have a
material  adverse  effect on the  aggregate  value of the  Collateral  or on the
security interests granted to the Agent in this Security Agreement.

Section 4.16.  Change of Law. The Debtor shall promptly  notify the Agent of any
change in law known to it which (i) adversely  affects or will adversely  affect
the validity,  perfection or priority of the security  interests granted hereby,
(ii)  requires  or will  require a change in the  proceedings  to be followed in
order to maintain and protect such  validity,  perfection  and priority or (iii)
could result in the Agent not having a perfected security interest in any of the
Collateral.

Section 4.17.     Right of Inspection.

(a) Access to Books and Records. The Debtor shall,  following any request by the
Agent and upon reasonable  notice,  permit the Agent or its  representatives  to
have  full  and free  access  during  normal  business  hours to all the  books,
correspondence and records of the Debtor,  and the Agent or its  representatives
may examine the same, take extracts therefrom, make photocopies thereof and have
such discussions with officers,  employees and public  accountants of the Debtor
as the Agent may deem reasonably  necessary,  and the Debtor agrees to render to
the Agent, at the Debtor's cost and expense,  such clerical and other assistance
as  may  be  reasonably  requested  with  regard  thereto.  The  Agent  and  its
representatives  shall upon  reasonable  notice and during normal business hours
also  have the  right to enter  into  and  upon any  premises  where  any of the
Inventory or the  Equipment is located for the purpose of  inspecting  the same,
observing its use or protecting the interests of the Agent therein.

(b)  Audits.  The  Debtor  shall  permit  the  Lenders,   the  Agent  and  their
representatives  and advisors to review the operations of the Debtor and perform
the audits and  examinations  as  provided  in Section  6.1(l) of the  Revolving
Credit Agreement.

     Section 4.18.  Maintenance  of Equipment.  The Debtor will, at its expense,
     maintain the Equipment in good operating condition,  ordinary wear and tear
     excepted.

Section 4.19.     Covenants Regarding Patent and Trademark Collateral.

(a)  Generally.  At  such  time as the  Debtor  shall  acquire  any  Patents  or
Trademarks,  it will comply with the terms,  covenants  and  warranties  of this
Section 4.19.

(b) Continued Use of Trademark.  The Debtor (either itself or through licensees)
will, unless the Debtor shall reasonably determine,  after consultation with the
Agent,  that a Trademark  is of  negligible  economic  value to the Debtor,  (i)
continue  to use each  Trademark  on each  and  every  Trademark  class of goods
applicable  to its current  products  and  services as  reflected in its current
catalogs,  brochures and price lists in order to maintain each Trademark in full
force and free from any claim of  abandonment  for non-use,  (ii) maintain as in
the past the quality of products  and  services  offered  under each  Trademark,
(iii) employ each Trademark with the appropriate  notice of  registration,  (iv)
not adopt or use any mark which is confusingly  similar to a colorable imitation
of any Trademark and (v) not (and not permit any licensee or sublicensee thereof
to) do any act or knowingly  omit to do any act whereby any Trademark may become
invalidated.

(c) No  Abandonment.  The Debtor will not,  unless the Debtor  shall  reasonably
determine,  after  consultation  with the Agent,  that a Patent is of negligible
economic  value to the  Debtor,  do any act,  or  knowingly  omit to do any act,
whereby any Patent may be abandoned or dedicated.

(d) Notice of Abandonment or Adverse Determinations. The Debtor shall notify the
Agent  immediately if it knows,  or has reason to know,  that any application or
registration  relating  to any  Patent or  Trademark  may  become  abandoned  or
dedicated,  or of any adverse determination or development  (including,  without
limitation,  the institution of, or any such determination or development in any
proceeding  in the United  States  Patent and  Trademark  Office or any court of
tribunal in any  country)  regarding  the  Debtor's  ownership  of any Patent or
Trademark, its right to register the same or keep and maintain the same.

(e) Filings After Notice to Agent.  In no event shall the Debtor,  either itself
or through any agent,  employee,  licensee or designee,  file an application for
registration  of any  Patent or  Trademark  with the  United  States  Patent and
Trademark  Office or any  similar  office or agency in any other  country or any
political  subdivision  thereof,  unless it promptly informs the Agent and, upon
request of the Agent, executes and delivers any and all agreements, instruments,
documents  and papers as the Agent may request to evidence the Agent's  security
interest in such Patent or Trademark and the goodwill and general intangibles of
the  Debtor  relating  thereto or  represented  thereby,  and the Debtor  hereby
constitutes the Agent its attorney-in-fact to execute and file all such writings
for the foregoing purposes, all such acts of such attorney being hereby ratified
and confirmed.

(f) Pursuit of Applications  and Maintenance of  Registrations.  The Debtor will
take all necessary  steps,  including,  without  limitation,  in any  proceeding
before the United States Patent and  Trademark  Office or any similar  office or
agency in any other country or any political  subdivision  thereof,  to maintain
and pursue each  application  (and to obtain the relevant  registration)  and to
maintain each  registration  of the Patents and  Trademarks,  including  without
limitation, filing of applications for renewal, affidavits of use and affidavits
of incontestability;  provided,  however, that no such Patent or Trademark shall
be required to be  maintained  or pursued to the extent such Patent or Trademark
is  determined  by the  Debtor,  after  consultation  with the  Agent,  to be of
negligible economic value to the Debtor.

(g) Notice of  Infringement.  If any of the Patent and  Trademark  Collateral is
infringed,  misappropriated  or  diluted  by a third  party,  the  Debtor  shall
promptly  notify the Agent after it learns thereof and shall,  unless the Debtor
shall reasonably determine,  after consultation with the Agent, that such Patent
and Trademark Collateral is of negligible economic value to the Debtor, promptly
sue for infringement, misappropriation of dilution, seek injunctive relief where
appropriate   and  recover   any  and  all   damages   for  such   infringement,
misappropriation  or  dilution,  or take such other  action as the Debtor  shall
reasonably deem appropriate  under the  circumstances to protect such Patent and
Trademark Collateral.

Section 4.20.  Termination  of Federal  Contracts.  With respect to each Federal
Contract in respect of which the Debtor is required to execute an  Assignment of
Federal  Contract in accordance with Section 4.21 hereof,  the Debtor shall give
prompt written  notice to the Agent if the U.S.  Government  shall  terminate or
threaten to  terminate  (whether  for  convenience  or default) any such Federal
Contract  with the Debtor  having a value  (including  unexercised  options)  of
$100,000 or more. In addition,  the Debtor shall give prompt  written  notice to
the Agent if the U.S.  Government  shall  terminate or threaten to terminate any
contract between the U.S.  Government and any other prime contractor under which
the  Debtor  is a  subcontractor  if the  value of such  subcontract  (including
unexercised  options) is $100,000 or more. Section 4.21. Federal Contracts.  The
Debtor shall  provide to the Agent,  as soon as reasonably  practicable  but not
later than  forty-five  (45) days  following the end of each Fiscal  Quarter,  a
report identifying each Federal Contract to which it is a party, having attached
thereto a copy of the first two pages of such Federal Contract and any amendment
thereto,  to the extent not previously  provided to the Agent. At the request of
the Agent (unless an Event of Default shall have occurred and be continuing,  in
which case no such request  shall be  required),  the Debtor  shall  execute and
deliver to the Agent an Assignment of Federal  Contract,  in  substantially  the
form of Exhibit A hereto (the "Assignment of Federal Contract"), and execute any
other  instruments  or take any other steps  required by the Agent in order that
all moneys due or to become due under such Federal  Contracts  shall be assigned
to the Agent and  notice  thereof  given  under the  Assignment  of Claims  Act,
including without limitation  delivery of Notices of Assignments with respect to
each Federal Contract as contemplated by Appendix A to Exhibit A hereto.

Section 4.22.  Reimbursement  Obligation.  Should the Debtor fail to comply with
the provisions of this Security Agreement, the Revolving Credit Agreement or any
other agreement relating to the Collateral such that the value of any Collateral
or the validity,  perfection,  rank or value of any security interest granted to
the  Agent  hereunder  or  thereunder  is  thereby   diminished  or  potentially
diminished or put at risk (as reasonably  determined by the Agent), the Agent on
behalf of the Debtor may, but shall not be required to,  effect such  compliance
on behalf of the Debtor,  and the Debtor shall  reimburse the Agent for the cost
thereof on demand,  and interest shall accrue on such  reimbursement  obligation
from the date the relevant  costs are incurred  until  reimbursement  thereof in
full at the Default Rate.

ARTICLE V.

                                      REMEDIES; RIGHTS UPON DEFAULT

Section 5.01. UCC Rights.  In the event that any portion of the  Obligations has
been declared or becomes due and payable in accordance with the Revolving Credit
Agreement or other Credit  Documents and such  Obligations have not been paid in
full,  the Agent may in addition to all other rights and remedies  granted to it
in this Security  Agreement and in any other  instrument or agreement  securing,
guarantying,  evidencing or relating to the Obligations, exercise (i) all rights
and  remedies of a secured  party under the UCC (whether or not in effect in the
jurisdiction  where  such  rights  are  exercised)  and  (ii) all  other  rights
available to the Agent at law or in equity.

     Section 5.02.  Payments on Collateral.  Without  limiting the rights of the
     Agent under any other provision of this Security Agreement,  if an Event of
     Default shall occur and be continuing:

(i) all payments  received by the Debtor under or in connection  with any of the
Collateral  shall  be held by the  Debtor  in  trust  for the  Agent,  shall  be
segregated  from other funds of the Debtor and shall  forthwith  upon receipt by
the Debtor be turned  over to the  Agent,  in the same form as  received  by the
Debtor  (duly  indorsed  by the  Debtor  to the  Agent,  if  required  to permit
collection thereof by the Agent); and

(ii) all such  payments  received  by the  Agent  (whether  from the  Debtor  or
otherwise)  may, in the sole  discretion  of the Agent,  be held by the Agent as
collateral  security for, and/or then or at any time thereafter applied in whole
or in part by the Agent to the payment of, the expenses and the  Obligations  as
set forth in Section 5.11 hereof.

Section 5.03.  Possession of Collateral.  In  furtherance of the foregoing,  the
Debtor  expressly  agrees  that,  if an  Event of  Default  shall  occur  and be
continuing, the Agent may (i) by judicial powers, or without judicial process if
it can be done without breach of the peace, enter any premises where any of such
Collateral is or may be located and,  without  charge or liability to the Agent,
seize and remove such  Collateral from such premises and (ii) have access to and
use of the Debtor's books and records relating to such Collateral.

Section 5.04.     Sale of Collateral; Notice.

(a) Sale of Collateral.  The Debtor expressly agrees that if an Event of Default
shall occur and be continuing, the Agent, without demand of performance or other
demand or notice of any kind (except the notice  specified below of the time and
place of any public or private  sale) to or upon the Debtor or any other  Person
(all of which  demands  and/or  notices are hereby  waived by the  Debtor),  may
forthwith (i) apply the cash, if any, then held by it as collateral as specified
in Section  5.11 hereof and (ii) if there shall be no cash or such cash shall be
insufficient to pay the Obligations in full, collect,  receive,  appropriate and
realize upon the Collateral,  and/or sell, assign,  give an option or options to
purchase or otherwise  dispose of and deliver the  Collateral (or contract to do
so) or any part thereof in one or more parcels (which need not be in round lots)
at public or  private  sale,  at any  office of the Agent or  elsewhere  in such
manner as is  commercially  reasonable and, as the Agent may deem best, for cash
or on credit or for future delivery  without  assumption of any credit risk. The
Agent shall have the right upon any such public sale,  and, if the Collateral is
of a type customarily  sold in a recognized  market or is of a type which is the
subject of widely distributed  standard price quotations,  upon any such private
sale or sales,  to purchase the whole or any part of the Collateral so sold, and
thereafter to hold the same,  absolutely and free from any right or claim of any
kind. To the extent  permitted by applicable  law, the Debtor waives all claims,
damages  and  demands  against  the  Agent  arising  out  of  the   foreclosure,
repossession, retention or sale of the Collateral.

(b) Notice of Sale. Unless the Collateral threatens to decline speedily in value
or is of a type  customarily sold on a recognized  market,  the Agent shall give
the Debtor  ten (10)  days'  written  notice of its  intention  to make any such
public or private sale or sale at a broker's board or on a securities  exchange.
Such  notice  shall (i) in the case of a public  sale,  state the time and place
fixed  for  such  sale,  (ii) in the  case of sale at a  broker's  board or on a
securities  exchange,  state the board or  exchange  at which such sale is to be
made and the day on which the  Collateral,  or the portion  thereof  being sold,
will first be offered  for sale and (iii) in the case of a private  sale,  state
the day after which such sale may be consummated.  The Agent shall not obligated
to make any such sale  pursuant  to any such  notice.  The Agent may adjourn any
public or private  sale or cause the same to be  adjourned  from time to time by
announcement at the time and place fixed for the sale, and such sale may be made
at any time or place to which the same may be so  adjourned.  In the case of any
sale of all or any part of the Collateral on credit or for future delivery,  the
Collateral  so sold may be retained by the Agent until the selling price is paid
by the purchaser thereof, but the Agent shall not incur any liability in case of
the failure of such purchase to take up and pay for the  Collateral so sold and,
in the case of such failure, such Collateral may again be sold upon like notice.

(c) Special  Provisions  Relating to Sales of Securities.  The Debtor recognizes
that  the  Agent  may be  unable  to  effect  a  public  sale  of any or all the
Collateral  constituting a "security" (as such term is defined in the Securities
Act) by reason of  certain  prohibitions  contained  in the  Securities  Act and
applicable state securities laws or otherwise, and may be compelled to resort to
one or more private sales thereof to a restricted  group of purchasers that will
be obliged to agree,  among other things,  to acquire such  securities for their
own account for  investment  and not with a view to the  distribution  or resale
thereof.  The Debtor  acknowledges  and agrees  that any such  private  sale may
result in prices and other terms less  favorable than if such sale were a public
sale and, notwithstanding such circumstances,  agrees that any such private sale
shall be deemed to have been made in a commercially reasonable manner. The Agent
shall be under no obligation to delay a sale of any of Collateral constituting a
security  for the  period of time  necessary  to permit  the  issuer  thereof to
register  such  securities  for public sale under the  Securities  Act, or under
applicable state securities laws, even if such issuer would agree to do so.

Section 5.05.  Rights of Purchasers.  Upon any sale of the  Collateral  (whether
public or  private),  the Agent  shall  have the right to  deliver,  assign  and
transfer  to the  purchaser  thereof  the  Collateral  so sold.  Each  purchaser
(including  the  Agent)  at any such  sale  shall  hold the  Collateral  so sold
absolutely,  free from any claim or right of whatever kind, including any equity
or right of redemption of the Debtor who, to the extent permitted by law, hereby
specifically waives all rights of redemption, including, without limitation, any
right to redeem the Collateral  under Section 9-506 of the UCC, and any right to
a judicial or other stay or approval  which it has or may have under any law now
existing or hereafter adopted.

Section 5.06.     Additional Rights of the Agent.

(a) Right to Maintain Proceedings.  The Agent (i) shall have the right and power
to institute and maintain such suits and proceedings as it may deem  appropriate
to protect and enforce the rights  vested in it by this  Security  Agreement and
(ii) may proceed by suit or suits at law or in equity to enforce such rights and
to foreclose  upon the  Collateral and to sell all or, from time to time, any of
the   Collateral   under  the  judgment  or  decree  of  a  court  of  competent
jurisdiction.

(b)  Appointment  of  Receiver.  The Agent  shall,  to the extent  permitted  by
applicable law,  without notice to the Debtor to any party claiming  through the
Debtor,  without regard to the solvency or insolvency at such time of any Person
then liable for the  payment of any of the  Obligations,  without  regard to the
then value of the Collateral and without requiring any bond from any complainant
in such  proceedings,  be entitled as a matter of right to the  appointment of a
receiver  or  receivers  (who may be the  Agent) of the  Collateral  or any part
thereof,  pending  such  proceedings,  with such powers as the court making such
appointment  shall  confer,  and to the  entry  of an order  directing  that the
profits, revenues and other income of the property constituting the whole or any
part of the Collateral be segregated,  sequestered and impounded for the benefit
of the Agent,  and the Debtor  irrevocably  consents to the  appointment of such
receiver or receivers and to the entry of such order.

(c) No Duty to  Exercise  Rights.  In no event  shall the Agent have any duty to
exercise any rights or take any steps to preserve the rights of the Agent in the
Collateral,  nor shall the Agent be liable to the Debtor or any other Person for
any loss caused by the Agent's failure to meet any obligation imposed by Section
9-207 of the UCC or any successor provision. Without limiting the foregoing, the
Agent  shall be deemed to have  exercised  reasonable  care in the  custody  and
preservation  of the  Collateral in its possession if the Collateral is accorded
treatment  substantially equal to that which the Agent accords its own property,
it being understood that the Agent shall not have any duty or responsibility for
(i) ascertaining or taking action with respect to calls, conversions, exchanges,
maturities,  tenders or other matters relative to any Collateral, whether or not
the Agent has or is deemed to have knowledge of such matters, or (ii) taking any
necessary  steps to preserve  rights  against any  parties  with  respect to any
Collateral.

Section 5.07.     Remedies Not Exclusive, etc.

(a) Remedies Not Exclusive. No remedy conferred upon or reserved to the Agent in
this  Security  Agreement  is intended to be  exclusive  of any other  remedy or
remedies,  but every such remedy shall be cumulative and shall be in addition to
every other  remedy  conferred  herein or now or  hereafter  existing at law, in
equity or by statute.

(b)  Restoration  of Rights.  If the Agent shall have  proceeded  to enforce any
right,  remedy or power under this Security Agreement and the proceeding for the
enforcement  thereof shall have been discontinued or abandoned for any reason or
shall have been  determined  adversely  to the  Agent,  the Debtor and the Agent
shall,   subject  to  any  determination  in  such  proceeding,   severally  and
respectively  be  restored  to their  former  positions  and  rights  under this
Security Agreement,  and thereafter all rights, remedies and powers of the Agent
shall continue as though no such proceedings had been taken.

(c)  Enforcement.  All rights of action  under this  Security  Agreement  may be
enforced by the Agent without the  possession of any  instrument  evidencing any
Obligation or the production  thereof at any trial or other proceeding  relative
thereto, and any suit or proceeding  instituted by the Agent shall be brought in
its name and any judgment shall be held as part of the Collateral.

Section 5.08.     Waiver and Estoppel.

(a) No Actions to Impede Sale of Collateral. The Debtor agrees, to the extent it
may lawfully do so, that it will not at any time in any manner  whatsoever claim
or take the benefit or advantage of any appraisal,  valuation,  stay, extension,
moratorium,  turnover or redemption  law, or any law permitting it to direct the
order in which the  Collateral  shall be sold,  now or at any time  hereafter in
force  which  may  delay,   prevent  or  otherwise  affect  the  performance  or
enforcement  of this  Security  Agreement,  and  hereby  waives  all  benefit or
advantage of all such laws. The Debtor covenants that it will not hinder,  delay
or impede  the  execution  of any power  granted  to the Agent in this  Security
Agreement, any Assignment of Federal Contract or any other Credit Document.

(b) Collateral Sold As An Entirety. The Debtor, to the extent it may lawfully do
so, on behalf of itself and all who claim through or under it, including without
limitation any and all  subsequent  creditors,  vendees,  assignees and lienors,
waives  and  releases  all  rights to demand or to have any  marshalling  of the
Collateral upon any sale, whether made under any power of sale granted herein or
pursuant to judicial  proceedings or under any foreclosure or any enforcement of
this Security Agreement,  and consents and agrees that all of the Collateral may
at any such sale be offered and sold as an entirety.

(c) Waiver of  Notices.  The Debtor  waives,  to the  extent  permitted  by law,
presentment,  demand,  protest  and any notice of any kind  (except  the notices
expressly required hereunder) in connection with this Security Agreement and any
action taken by the Agent with respect to the Collateral.

Section 5.09.     Power of Attorney; Powers Coupled With An Interest.

(a) Power of Attorney.  Without limiting any other right granted hereunder,  the
Debtor hereby irrevocably constitutes and appoints the Agent, with full power of
substitution,  as its true and  lawful  attorney-in-fact  with full  irrevocable
power and  authority in the place and stead of the Debtor and in the name of the
Debtor  or in its  own  name,  from  time  to  time  in the  Agent's  reasonable
discretion,  for the  purpose  of  carrying  out  the  terms  of  this  Security
Agreement,  to take any and all  appropriate  action and to execute  any and all
documents and instruments  which may be necessary or desirable to accomplish the
purpose of this Security  Agreement and,  without limiting the generality of the
foregoing,  hereby gives the Agent the power and right, on behalf of the Debtor,
without notice to or assent by the Debtor, to do the following:

     (i)  to  pay  or  discharge  taxes,  liens,  security  interests  or  other
     encumbrances levied or placed on or threatened against the Collateral;

(ii) to effect  any  repairs  or any  insurance  called for by the terms of this
Security  Agreement or any other Credit Document,  and to pay all or any part of
the premiums therefor and the costs thereof;

(iii) upon the occurrence and  continuance of any Event of Default and otherwise
to the  extent  provided  in this  Security  Agreement,  (A) to direct any party
liable for any payment  under any of the  Collateral  to make payment of any and
all moneys due and to come due thereunder  directly to the Agent or as the Agent
shall direct,  (B) to receive  payment of and receipt for, and to demand and sue
for, any and all moneys,  claims and other  amounts due and to become due at any
time in respect of or arising out of the Collateral, (C) to sign and indorse and
receive,  take, assign and deliver, any checks,  notes,  drafts,  negotiable and
non-negotiable  instruments,  any invoices,  freight or express bills,  bills of
lading,  storage or warehouse  receipts,  drafts against  debtors,  assignments,
verifications  and  notices in  connection  with  accounts  and other  documents
relating to the  Collateral,  (D) to  commence,  settle,  compromise,  compound,
prosecute,  defend or adjust any claim,  suit, action or proceeding with respect
to, or in connection  with, the  Collateral,  (E) to sell,  transfer,  assign or
otherwise  deal in or with the  Collateral  or any part  thereof,  as fully  and
effectively  as if the Agent were the absolute  owner  thereof and (F) to do, at
its option,  but at the expense of the Debtor, at any time or from time to time,
all acts and things  which the Agent deems  necessary  to  protect,  preserve or
realize upon the Collateral and the Agent's security interest therein,  in order
to effect the intent of this Security Agreement, all as fully and effectively as
the Debtor might do.

(b) Powers Coupled With an Interest.  All authorizations and agencies granted or
provided  herein with respect to the  Collateral,  including the powers  granted
under clause (a) of this Section 5.9, are irrevocable and powers coupled with an
interest.

Section 5.10. Certain Provisions Relating to Securities.  Solely with respect to
any Collateral  constituting a "security" (as defined in the Securities Act), if
an Event of Default shall have occurred and be continuing,  all such  securities
(as defined in the Securities Act)  constituting a part of the Collateral shall,
at the  request  of the  Agent,  be  registered  in the name of the Agent or its
nominee,  and the Agent or its nominee may  thereafter  exercise (i) all voting,
corporate and other rights,  powers and privileges pertaining to such Collateral
at any meeting of shareholders of the issuer thereof or otherwise,  and (ii) any
and all  rights of  conversion,  exchange,  subscription  and any other  rights,
privileges or options  pertaining to such  Collateral as if it were the absolute
owner  thereof  (including,  without  limitation,  the right to  exchange at its
discretion  any  and  all  such  Collateral  upon  the  merger,   consolidation,
reorganization, recapitalization or other fundamental change in the structure of
any such  issuer,  or upon the exercise by the Debtor or the Agent of any right,
privilege or option pertaining to such Collateral,  and in connection therewith,
the right to deposit and deliver any and all such Collateral with any committee,
depositary, transfer agent, registrar or other designated agency upon such terms
and conditions as it may determine), all without liability except to account for
property  actually  received  by it and except as  provided  in  Section  5.6(c)
hereof,  but the Agent  shall  have no duty to the Debtor to  exercise  any such
right, privilege or option and shall not be responsible for any failure to do so
or delay in so doing.

     Section 5.11.  Application of Monies. The proceeds of any sale of, or other
     realization upon, all or any part of the Collateral shall be applied by the
     Agent in the following order of priority:

                  first,  to  payment  of the  expenses  of such  sale or  other
realization,  including reasonable  compensation to the Agent and its agents and
counsel,  and all  expenses,  liabilities  and advances  incurred or made by the
Agent, its agents and counsel in connection  therewith or in connection with the
care, safekeeping or otherwise of any or all of the Collateral;

     second,  to  payment  of the  Obligations,  in such  order as the Agent may
     elect; and

                  third, any surplus then remaining shall be paid to the Debtor,
or its  successors  or assigns,  or to  whomsoever  may be lawfully  entitled to
receive the same (including  pursuant to Section 9-504(1)(C) of the UCC) or as a
court of competent jurisdiction may direct.

back has been  received,  in each  case if  addressed  to any  party  hereto  as
provided  herein.  Rejection or refusal to accept,  or the  inability to deliver
because of a changed address of which no notice was given,  shall not affect the
validity of notice given in accordance with this section.

Section 6.02.  No Waiver;  Cumulative  Remedies.  The Agent shall not by any act
(except by a written  instrument  pursuant  to Section  6.3 hereof) be deemed to
have waived any right or remedy hereunder. No failure to exercise, nor any delay
in exercising,  on the part of the Agent any right, power or privilege hereunder
shall operate as a waiver thereof.  No single or partial  exercise of any right,
power or  privilege  hereunder  shall  preclude  any other or  further  exercise
thereof or the exercise of any other right, power or privilege.  A waiver by the
Agent  of any  right  or  remedy  hereunder  on any one  occasion  shall  not be
construed as a bar to any right or remedy which the Agent would  otherwise  have
on any future occasion.  The rights and remedies herein provided are cumulative,
may be  exercised  singly or  concurrently  and are not  exclusive  of any other
rights or remedies provided by law.

Section 6.03.  Amendments  and Waivers.  None of the terms or provisions of this
Security Agreement may be amended,  supplemented or otherwise modified except by
a written  instrument  executed by the Debtor and the Agent;  provided  that any
provision of this  Security  Agreement may be waived by the Agent in a letter or
agreement  executed by the Agent or by telex or facsimile  transmission from the
Agent.

Section 6.04.  Successors and Assigns. The provisions of this Security Agreement
shall be binding  upon and inure to the benefit of the parties  hereto and their
respective  successors and assigns;  provided,  however, that the Debtor may not
assign or transfer any of its rights or obligations  hereunder without the prior
written consent of the Agent.

     Section 6.05.  Governing Law. THIS SECURITY  AGREEMENT SHALL BE GOVERNED BY
     AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE  COMMONWEALTH OF VIRGINIA,
     OTHER THAN ITS LAWS RESPECTING  CHOICE OF LAW OTHER THAN THOSE CONTAINED IN
     THE UCC.

Section 6.06.     Limitation by Law; Severability.

(a) All rights,  remedies and powers provided in this Security  Agreement may be
exercised  only to the extent  that the  exercise  thereof  does not violate any
applicable  provision of law, and all the provisions of this Security  Agreement
are intended to be subject to all applicable  mandatory  provisions of law which
may be controlling  and to be limited to the extent  necessary so that they will
not render this Security Agreement  invalid,  unenforceable in whole or in part,
or not entitled to be recorded,  registered or filed upon the  provisions of any
applicable law.

(b) If any provision hereof is invalid and  unenforceable  in any  jurisdiction,
then, to the fullest extent  permitted by law, (i) the other  provisions  hereof
shall  remain  in full  force  and  effect  in such  jurisdiction  and  shall be
liberally  construed in favor of the Agent in order to carry out the  intentions
of the parties  hereto as nearly as may be possible and (ii) the  invalidity  or
unenforceability  of any provision hereof in any  jurisdiction  shall not affect
the validity or enforceability of such provision in any other jurisdiction.

Section  6.07.  Counterparts.  This  Security  Agreement  may be executed in any
number of counterparts and by different parties hereto on separate counterparts,
each complete set of which, when so executed and delivered by all parties, shall
be an original,  but all such counterparts shall together constitute but one and
the same instrument.

Section 6.08. Expenses of the Agent. The Debtor shall pay to the Agent from time
to time upon demand,  all of the costs and expenses incurred by the Agent or any
Lender (including,  without limitation, the reasonable fees and disbursements of
counsel  and any  amounts  payable  by the  Agent or any  Lender to any of their
respective   agents)  (i)  arising  in  connection   with  the   administration,
modification, amendment, waiver or termination of this Security Agreement or any
document or agreement  contemplated hereby or any consent or waiver hereunder or
thereunder  or (ii)  incurred  in  connection  with the  administration  of this
Security  Agreement,  or any document or agreement  contemplated  hereby,  or in
connection  with the  administration,  sale or other  disposition  of Collateral
hereunder  or  under  any  document  or  agreement  contemplated  hereby  or the
preservation,  protection or defense of the rights of the Agent or any Lender in
and to the Collateral.

Section  6.09.  Indemnification.   The  Debtor  shall  at  all  times  hereafter
indemnify, hold harmless and, on demand, reimburse the Agent and the Lenders and
their  respective  subsidiaries,   affiliates,  successors,  assigns,  officers,
directors,   employees  and  agents,  and  their  respective  heirs,  executors,
administrators, successors and assigns (all of the foregoing parties, including,
but not limited to, the Agent, being hereinafter collectively referred to as the
"Indemnities" and individually as an "Indemnitee") from, against and for any and
all liabilities,  obligations,  claims, damages, actions,  penalties,  causes of
action, losses, judgments, suits, costs, expenses and disbursements,  including,
without  limitation,  attorney's  fees  (any  and  all  of the  foregoing  being
hereinafter  collectively referred to as the "Liabilities" and individually as a
"Liability")  which  the  Indemnitees,  or  any  of  them,  might  be or  become
subjected, by reason of, or arising out of the preparation, execution, delivery,
modification,  administration  or enforcement  of, or performance of the Agent's
rights  under,  this  Security  Agreement or any other  document,  instrument or
agreement  contemplated  hereby or executed in  connection  herewith;  provided,
however, that the Debtor shall not be liable to any Indemnitee for any Liability
caused solely by the gross negligence or willful  misconduct of such Indemnitee.
In no event shall any  Indemnitee,  as a condition to enforcing its rights under
this Section 6.9 or  otherwise,  be obligated to make a claim  against any other
Person (including,  without  limitation,  the Agent) to enforce its rights under
this Section 6.9.

Section 6.10.  Termination;  Survival.  This Security  Agreement shall terminate
when the security interests granted hereunder have terminated and the Collateral
has been  released as  provided  in Section  2.6;  provided,  however,  that the
obligations  of the Debtor under Section 4.22 and the provisions of this Article
6 shall survive any such termination.

Section  6.11.  Judicial  Proceedings;   Waiver  of  Jury  Trial.  Any  judicial
proceeding  brought  against  the Debtor  with  respect to any Credit  Agreement
Related  Claim hereby may be brought in any court of competent  jurisdiction  in
the  Commonwealth  of Virginia,  County of Fairfax,  or any Federal court in the
Eastern  District of Virginia,  and, by execution  and delivery of this Security
Agreement,   the  Debtor  (a)  accepts,   generally  and  unconditionally,   the
nonexclusive  jurisdiction  of such courts and any related  appellate  court and
irrevocably  agrees to be bound by any judgment  rendered  thereby in connection
with any Credit Agreement Related Claim and (b) irrevocably waives any objection
it may now or hereafter have as to the venue of any such  proceeding  brought in
such a court or that such a court is an  inconvenient  forum.  The Debtor hereby
waives personal  service of process and consents that service of process upon it
may be made by certified or registered mail,  return receipt  requested,  at its
address specified or determined in accordance with the provisions of Section 6.1
hereof,  and service so made shall be deemed completed on the earlier of (x) the
receipt  thereof and (y) if sent by registered or certified mail (return receipt
requested),  the fifth (5th) Business Day after such service is deposited in the
mail. Nothing herein shall affect the right of the Agent to serve process in any
other  manner  permitted  by law or shall  limit the right of the Agent to bring
proceedings  against  the  Debtor in the courts of any other  jurisdiction.  Any
judicial proceeding by the Debtor against the Agent relating to or involving any
Credit  Agreement  Related Claim hereby shall be brought only in a court located
in the Commonwealth of Virginia,  County of Fairfax, or the Federal court in the
Eastern  District of Virginia.  THE DEBTOR AND THE AGENT HEREBY  UNCONDITIONALLY
WAIVE  TRIAL  BY JURY IN ANY  JUDICIAL  PROCEEDING  TO WHICH  THEY  ARE  PARTIES
INVOLVING ANY CREDIT AGREEMENT RELATED CLAIM.

Section  6.12.  Integration.  This  Security  Agreement  and  the  other  Credit
Documents  constitute  the entire  agreement  of the  Agent,  the  Lenders,  the
Borrower and the other Credit  Parties with respect to the subject matter hereof
and  thereof,  and  there  are no  promises,  undertakings,  representations  or
warranties by the Agent or any Lender  relative to the subject  matter hereof or
thereof not  expressly  set forth or  referred to herein or in the other  Credit
Documents.

Section 6.13.  Authority of Agent. The Debtor  acknowledges  that the rights and
responsibilities  of the Agent under this Security Agreement with respect to any
action  taken by the Agent or the exercise or  non-exercise  by the Agent of any
option,  voting right,  request,  judgment or other right or remedy provided for
herein or resulting or arising out of this Security  Agreement shall, as between
the Agent and the Lenders,  be governed by the Revolving Credit Agreement and by
such other  agreements with respect thereto as may exist from time to time among
them, but, as between the Agent and the Debtor,  the Agent shall be conclusively
presumed to be acting as agent for the Lenders with full and valid  authority so
to act or refrain from acting, and the Debtor shall not be under any obligation,
or entitlement, to make any inquiry respecting such authority.

Exhibit A to
Security Agreement

                                                      FORM OF
                                          ASSIGNMENT OF FEDERAL CONTRACT


                  This  ASSIGNMENT OF FEDERAL  CONTRACT,  dated as of _____,  __
(the  "Agreement"),  is made by  THEODORE  BARRY AND  ASSOCIATES,  a  California
corporation (the "Assignor"), in favor of NATIONSBANK,  N.A., a national banking
association (the "Agent"), in its capacity as Agent for the lenders from time to
time a party to the  Revolving  Credit  Agreement  (as  defined in the  Security
Agreement referred to below).

                                               W I T N E S S E T H:

                  WHEREAS,   the  Assignor  has  secured   certain   obligations
undertaken  by Hagler  Bailly,  Inc.  pursuant to the  provisions  of a Security
Agreement,  dated as of  ___________________,  ____ (as the same may be amended,
supplemented or otherwise modified from time to time, the "Security Agreement"),
by and between the Assignor and the Agent; and

                  WHEREAS,  the  Assignor  is a party to,  and from time to time
will  become  entitled  to  receive  moneys  under and by  virtue  of, a certain
contract  with,  involving or for the benefit of the United States of America or
any department,  agency or  instrumentality  thereof (herein  referred to as the
"Government"),  designated  as  Contract  Number  _______  entered  into  by the
Assignor and the Government on ________ __, 19__ (which contract,  together with
all additions, change orders, supplements, amendments, renewals, extensions, and
modifications  thereto now or hereafter in effect, are hereinafter  collectively
called the "Contract"); and

                  WHEREAS,  pursuant to the Security Agreement, the Assignor has
undertaken to effectuate the  assignment(s)  and other actions  contemplated  by
this Agreement.

                  NOW,  THEREFORE,  in  consideration  of the premises and other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the Assignor covenants and agrees as follows:

         1. Incorporation By Reference. The provisions of the Security Agreement
are  incorporated  herein by  reference,  and the terms  defined in the Security
Agreement are used herein with the same meanings.

         2.  Representations.  The Assignor represents and warrants to the Agent
that (a) the Contract is legal,  valid and binding on the  Assignor  and, to its
knowledge,  the other parties thereto,  is in full force and effect,  and is not
evidenced  by any  chattel  paper or  instrument,  (b) upon due  filing  of this
Agreement,  together  with a Notice of Assignment  substantially  in the form of
Appendix A hereto with the authorized representative, the execution and delivery
of this Agreement does not violate and is not in conflict with the provisions of
the  Contract,  (c) there has been no default on the part of the Assignor or any
other party to the Contract, (d) the Assignor has made no previous assignment of
the  Contract to any person and knows of no fact or defense that will render the
moneys due or to be due  thereunder  uncollectible,  (e) no financing  statement
covering  the  Contract  is on  file  in  any  public  office  except  financing
statements in favor of the Agent,  (f) no set-off or  counterclaim to any moneys
due or to become  due  under the  Contract  exists  on the date  hereof,  and no
agreement  has been made with any person  under which any  deduction or discount
may be claimed,  and (g) the address of the office where the Assignor  keeps its
records concerning the Contract is ____________________.

         3. Collateral. As security and collateral for the payment of all of the
Obligations  (defined in the Security  Agreement)  and for  performance  of, and
compliance  with,  by the  Assignor,  all of the terms,  covenants,  conditions,
stipulations,  and  agreements  contained in this  Agreement and in the Security
Agreement,  the Assignor hereby assigns to the Agent,  and grants to the Agent a
lien on and  security  interest  in,  all  moneys  and claims for moneys now and
hereafter  due and to  become  due to the  Assignor  under or by  reason  of the
Contract,  together  with all  cash and  non-cash  proceeds  thereof;  provided,
however,  that nothing  contained  herein shall impose upon the Agent any of the
obligations or liabilities of the Assignor under the Contract.

         4. Covenants. Until payment and performance in full of the Obligations,
the Assignor covenants as follows:

(c) The  Assignor  shall  place  on any and all  vouchers,  invoices,  or  other
instruments demanding payment under the Contract the direction that such payment
is to be made to the Agent in accordance with Section 5 of this Agreement.

(d) The Assignor shall promptly upon request execute,  acknowledge,  and deliver
any  notice,  financing  statement,   renewal,   affidavit,   deed,  assignment,
continuation statement,  security agreement,  certificate,  or other document as
the  Agent  may  require  in  order to  perfect,  preserve,  maintain,  protect,
continue, and/or extend the assignment, lien, and security interest of the Agent
under this  Agreement and its priority.  The Assignor  shall pay to the Agent on
demand all taxes,  costs, and expenses  incurred by the Agent in connection with
the  preparation,  execution,  recording,  and  filing of any such  document  or
instrument  mentioned  aforesaid,  and such taxes,  costs,  and  expenses  shall
constitute  and become a part of the  Obligations.  A carbon,  photographic,  or
other  reproduction  of  a  security  agreement  or  a  financing  statement  is
sufficient as a financing statement.

(e) The Assignor shall fully,  promptly,  and faithfully comply with and perform
its  obligations  and duties  under the  Contract in  accordance  with the terms
thereof and will make no changes or  amendments  to the Contract or terminate or
cancel the  Contract  without the prior  written  consent of the Agent except as
permitted by the Security  Agreement.  In the event that any change,  amendment,
termination  or  cancellation  of  the  Contract  is  made  or  effected  by the
Government,  the Assignor  will  promptly  notify the Agent thereof and promptly
furnish to the Agent a copy of any  document or  agreement  evidencing  any such
change, amendment, termination, or cancellation.

(f)      The Assignor will promptly

     (i) furnish to the Agent all information received by the Assignor affecting
     the moneys due and to become due under the Contract,

     (ii)  inform the Agent of any delay in  performance  of, or claims  made in
     regard to, the Contract, and

(iii) notify the Agent in writing of the failure of any party to the Contract to
perform any of its  obligations  thereunder and any rejection of any performance
rendered by the Assignor under or in connection with the Contract.

(g) The  Assignor  will at all times  keep  accurate  and  complete  records  of
performance  by the Assignor  under the  Contract,  and the Agent and its agents
shall have the right,  during normal business hours and upon reasonable  advance
notice,  to call at the place or places of business of the Assignor at intervals
to be  determined  by the Agent,  and without  hindrance  or delay,  to inspect,
audit,  check,  and make extracts  from the books,  records,  journals,  orders,
receipts,  correspondence,  and other data  relating  to the  Contract or to any
other transactions between the parties hereto related to the Contract.

         5. Payments. The Assignor hereby authorizes,  empowers, and directs the
Government to draw all checks,  drafts,  or other  instruments  representing the
payments of money due the Assignor under the Contract  (herein called the "Items
of Payment") to the order of  NationsBank,  N.A.,  assignee of Assignor,  and to
send  the  same  (i)  if by  mail,  to ,  (ii)  if by  electronic  transfer,  to
NationsBank, N.A. for the account of ________________, Bank Account #__________,
Agent ABA#_________,  or (iii) if by wire transfer, to NationsBank, N.A. for the
account of  _________________________,  Bank Account #_______,  ABA#___________.
If, despite this  direction,  any  instruments or checks  representing  payments
should be delivered to the Assignor,  the Assignor will immediately  endorse and
deliver such  instruments or checks to the order of the Agent. The Assignor does
hereby  irrevocably  (subject  to  revocation  with the  consent  of the  Agent)
designate and appoint (which appointment is coupled with an interest) the Agent,
and the Agent's  successors in interest by operation of law, the Assignor's true
and  lawful  attorney  with  power  irrevocable  for  the  Assignor  and  in the
Assignor's  name,  place,  and  stead,  but at the sole cost and  expense of the
Assignor,  to receive,  endorse,  and collect all Items of Payment,  and to ask,
demand,  receive,  receipt,  and give acquittances for any and all amounts which
may be payable  or which  become due and  payable  by the  Government  under the
Contract,  and in the Agent's  discretion to file any claim or to take any other
action  or  proceeding,  either  in the  Agent's  own name or in the name of the
Assignor or otherwise,  which to the Agent or any successor in interest  thereof
may seem  necessary  or  desirable in order to collect or endorse the payment of
any and all amounts now due or owing or which may  hereafter be or become due or
owing on account of the  Contract.  All Items of Payment  received  by the Agent
pursuant  hereto  which are  finally  paid in cash or solvent  credits  shall be
applied  against the  Obligations  as provided in the  Security  Agreement.  Any
portion of the Items of Payment  which the Agent elects not to so apply shall be
paid over to the  Assignor  or to  whomsoever  shall be entitled  thereto  under
applicable  law,  including  pursuant  to  Section  9-504(1)(C)  of the  Uniform
Commercial Code of the Commonwealth of Virginia.

         6.  No  Waiver.   Neither  this  Agreement  nor  any  term,  condition,
representation,  warranty, covenant, or agreement hereof may be changed, waived,
discharged,  or terminated  orally,  but only by an instrument in writing by the
party against whom such change, waiver, discharge, or termination is sought.

         7. Governing law. THIS AGREEMENT  SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE  WITH THE LAWS OF THE  COMMONWEALTH  OF VIRGINIA,  WITHOUT  REGARD TO
PRINCIPLES OF CONFLICTS OF LAWS.

         8. Gender.  Whenever used herein, the singular number shall include the
plural,  the plural the singular,  and the use of the  masculine,  feminine,  or
neuter gender shall include all genders.

         9.  Counterparts.  This  Agreement  may be  executed  in any  number of
duplicate  originals,  each of  which  shall  be an  original  but all of  which
together shall constitute one and the same instrument.

         10. Paragraph  Headings.  The paragraph  headings of this Agreement are
for  convenience  only and  shall not limit or  define  the  provisions  of this
Agreement.

Section  2.01.  Grant of  Security  Interests.  To secure  the due and  punctual
payment of all Obligations,  howsoever  created,  arising or evidenced,  whether
direct or indirect,  absolute or contingent, now or hereafter existing or due or
to become  due,  whether at  maturity  or upon  acceleration  or  otherwise,  in
accordance with the terms thereof and to secure the due and punctual performance
of all of the Obligations and in order to induce the Lenders to continue to make
or maintain the extensions of credit under and pursuant to the Revolving  Credit
Agreement, the Debtor hereby pledges, assigns,  delivers,  conveys and transfers
to the Agent,  for the ratable benefit of the Lenders,  and grants to the Agent,
for the ratable benefit of the Lenders, a first priority and continuing security
interest in and lien on, all of the  Debtor's  right,  title and interest in, to
and under the  following,  whether  now  existing  or  hereafter  acquired  (the
"Collateral"):

(i)      all Receivables;

(ii)     all Other Intangibles;

(iii)    all Equipment;

(iv)     all Inventory;

(v) to the  extent  not  included  in the  foregoing,  all  securities  (whether
certificated or uncertificated)  and all financial assets,  whether now existing
or hereafter arising, including, without limitation, all capital stock issued by
any Person and held by Debtor,  and all  partnership  interests,  whether in the
nature of a joint venture,  limited liability company member's interest,  master
limited partnership, teaming arrangement or otherwise;

(vi) to the extent not included in the foregoing,  all other personal  property,
whether  tangible or intangible,  and wherever located whether within or outside
of the United  States,  including,  but not  limited  to,  the  balance of every
deposit  account now or hereafter  existing of the Debtor with any bank or other
financial  institution and all monies of the Debtor and all rights to payment of
money of the Debtor;

(vii) to the extent not  included  in the  foregoing,  all  books,  ledgers  and
records and all computer  programs,  tapes,  discs, punch cards, data processing
software,  transaction  files,  master  files and  related  property  and rights
(including computer and peripheral equipment) necessary or helpful in enforcing,
identifying or establishing any item of Collateral; and

(viii) to the extent not otherwise included, all Proceeds and products of any or
all of the foregoing, whether existing on the date hereof or arising hereafter;

provided,  however,  notwithstanding  anything to the contrary contained herein,
the  Debtor is not  assigning,  pledging  or  otherwise  encumbering  under this
Security Agreement its interests in any Federal Contract to which it is a party,
or in accounts or receivables due to Debtor under such Federal Contract,  to the
extent,  but only to the extent,  such assignment,  pledge or other  encumbrance
would  breach or violate or would cause Debtor to breach or violate such Federal
Contract or statutes or regulations applicable thereto, it being understood that
this proviso does not apply to, or in any way limit, Debtor's assignment, pledge
or encumbrance of Proceeds of all Federal Contracts to which it is a party.

Section  2.02.  Continuing  Liability  of the  Debtor.  Anything  herein  to the
contrary notwithstanding,  the Debtor shall remain liable to observe and perform
all the  terms and  conditions  to be  observed  and  performed  by it under any
contract,   agreement,   warranty  or  other  obligation  with  respect  to  the
Collateral;  and  shall do  nothing  to impair  the  security  interests  herein
granted.  The Agent shall not have any  obligation  or liability  under any such
contract,  agreement, warranty or obligation by reason of or arising out of this
Security  Agreement  or the receipt by the Agent of any payment  relating to any
Collateral,  nor shall the Agent be  required  to perform or fulfill  any of the
obligations of the Debtor with respect to the Collateral, to make any inquiry as
to the nature or sufficiency of any payment received by it or the sufficiency of
the  performance  of any party's  obligations  with  respect to any  Collateral.
Furthermore,  the  Agent  shall not be  required  to file any claim or demand to
collect any amount due or to enforce the performance of any party's  obligations
with respect to, the Collateral.

Section 2.03.     Sales and Collections.

(a) Sales of  Inventory  in the  Ordinary  Course  of  Business.  The  Debtor is
authorized (i) to sell in the ordinary course of its business for fair value and
on an  arm's-length  basis  any of its  Inventory  normally  held by it for such
purpose and (ii) to use and consume, in the ordinary course of its business, any
raw materials,  supplies and materials normally held by it for such purpose. The
Agent may, upon the occurrence of any Event of Default, without cause or notice,
curtail or terminate such authority at any time.

(b) Collection of Receivables. The Debtor is authorized to collect amounts owing
to it with respect to the Collateral, except as otherwise provided in connection
with the Assignment of Federal Contract, if any as provided herein. However, the
Agent may, upon and during the continuance of an Event of Default or a Potential
Event of Default, notify Account Debtors obligated to make payments under any or
all Receivables or Other  Intangibles that the Agent has a security  interest in
such Collateral and that payments shall be made directly to the Agent.  Upon the
request of the Agent upon and during the continuance of an Event of Default or a
Potential  Event of Default,  as the case may be, the Debtor will so notify such
Account  Debtors  and  will  execute  such  contract  assignments,   notices  of
assignment or other  documents as may be required by such Account  Debtors.  The
Debtor will use all  reasonable  efforts to cause each Account  Debtor to comply
with the foregoing  instruction.  In furtherance  of the  foregoing,  the Debtor
authorizes the Agent upon and during the continuance of an Event of Default or a
Potential  Event of Default (i) to ask for,  demand,  collect,  receive and give
acquittances  and  receipts  for any and all amounts due and to become due under
any Collateral and in the name of the Debtor or its own name or otherwise,  (ii)
to  take  possession  of,  endorse  and  collect  any  checks,   drafts,  notes,
acceptances  or other  instruments  for the  payment  of  monies  due  under any
Collateral  and (iii) to file any claim or take any other action in any court of
law or equity or  otherwise  which it may deem  appropriate  for the  purpose of
collecting  any  amounts  due under any  Collateral.  The  Agent  shall  have no
obligation  to obtain or record any  information  relating to the source of such
funds or the obligations in respect of which payments have been made.

Section 2.04.     Segregation of Proceeds.

(a) Cash Collateral  Account  Maintained by Agent. Upon an Event of Default or a
Potential  Event of  Default,  the Agent shall have the right at any time during
the  continuance  thereof to cause to be opened and  maintained at the office of
the Agent in McLean,  Virginia a  non-interest  bearing  bank account (the "Cash
Collateral  Account") which will contain only Proceeds.  Any "cash proceeds" (as
such term is defined  in  Section  9-306(1)  of the UCC)  received  by the Agent
directly from Account  Debtors  obligated to make payments under  Receivables or
Other Intangibles  pursuant to Section 2.3 hereof or from the Debtor pursuant to
clause (b) of this Section 2.4,  whether  consisting of checks,  notes,  drafts,
bills of exchange, money orders,  commercial paper or other Proceeds received on
account of any  Collateral,  shall be promptly  deposited in the Cash Collateral
Account, and until so deposited shall be held in trust for the Agent as property
of the  Agent  and shall not be  commingled  with any  funds of the  Debtor  not
constituting  Proceeds  of  Collateral.  The name in which  the Cash  Collateral
Account is carried shall clearly  indicate that the funds deposited  therein are
the  property  of the  Debtor,  subject to the  security  interest  of the Agent
hereunder. Such Proceeds, when deposited,  shall continue to be security for the
Obligations   and  shall  not  constitute   payment  thereof  until  applied  as
hereinafter  provided.  The Agent shall have sole  dominion and control over the
funds deposited in the Cash Collateral Account,  and such funds may be withdrawn
therefrom only by the Agent.

(b) Deposit of  Proceeds  by the Debtor.  Upon notice by the Agent to the Debtor
that the Cash  Collateral  Account has been  opened,  the Debtor shall cause all
cash  Proceeds  collected  by it to be  delivered  to the Agent  forthwith  upon
receipt,  in the original  form in which  received  (with such  endorsements  or
assignments as may be necessary to permit collection  thereof by the Agent), and
for such  purpose the Debtor  hereby  irrevocably  authorizes  and  empowers the
Agent,  its officers,  employees and  authorized  agents to endorse and sign the
name of the Debtor on all checks, drafts, money orders or other media of payment
so delivered,  and such endorsements or assignments shall, for all purposes,  be
deemed to have been made by the Debtor prior to any  endorsement  or  assignment
thereof by the Agent.  The Agent may use any  convenient or customary  means for
the purpose of collecting  such checks,  drafts,  money orders or other media of
payment.

Section 2.05.  Verification  of  Receivables.  The Agent shall have the right to
make test  verifications of Receivables in any reasonable manner and through any
medium that it considers  advisable,  and the Debtor  agrees to furnish all such
assistance and  information  as the Agent may  reasonably  require in connection
therewith.  The Debtor at its expense will cause its chief financial  officer to
furnish to the Agent at any reasonable time and from time to time, promptly upon
the Agent's reasonable request,  the following reports:  (i) a reconciliation of
all Receivables, (ii) an aging of all Receivables, (iii) trial balances and (iv)
a test verification of such Receivables as the Agent may request.

Section 2.06.     Release of Collateral.

(a) Security  Interest of Agent Ceases Upon Permitted  Dispositions.  The Debtor
may sell or realize upon or transfer or otherwise  dispose of Collateral only to
the extent permitted by Section 4.13, and the security interests of the Agent in
such  Collateral so sold,  realized upon or disposed of (but not in the Proceeds
arising from such sale, realization or disposition) shall cease immediately upon
such sale, realization or disposition, without any further action on the part of
the Agent.  The Agent,  if requested in writing by the Debtor but at the expense
of the Debtor,  is hereby  authorized  and  instructed to deliver to the Account
Debtor or the purchaser or other transferee of any such Collateral a certificate
stating  that the Agent no longer  has a  security  interest  therein,  and such
Account Debtor or such purchaser or other  transferee  shall be entitled to rely
conclusively on such certificate for any and all purposes.

(b) Filing of  Termination  Statements.  Upon the  payment in full of all of the
Obligations  and if  there  is no  commitment  by any  Lender  to  make  further
advances,  incur obligations or otherwise give value, the Agent will (as soon as
reasonably  practicable  after receipt of notice from the Debtor  requesting the
same but at the  expense  of the  Debtor)  deliver  to the  Debtor  (i) for each
jurisdiction  in  which a UCC  financing  statement  is on file to  perfect  the
security  interests  granted to the Agent  hereunder,  a  termination  statement
(appropriately  completed)  to the  effect  that the  Agent no  longer  claims a
security interest under such financing statement,  and (ii) such other documents
as  the  Debtor  shall  reasonably  request   evidencing   satisfaction  of  the
Obligations  and the  release  of the  security  interests  granted to the Agent
hereunder.

ARTICLE III.

                                      REPRESENTATIONS AND WARRANTIES

         The Debtor represents and warrants that:

Section 3.01. Title to Collateral.  Except for the security interests granted to
the Agent  pursuant to this  Security  Agreement  and as otherwise  permitted by
Section 6.2(a) of the Revolving Credit  Agreement,  the Debtor is the sole owner
of each item of the Collateral,  having good and marketable title thereto,  free
and clear of any and all Liens.

Section 3.02.     Validity, Perfection and Priority of Security Interests.

(a) By complying  with Section 4.1 hereof,  the Debtor will have created a valid
security  interest in favor of the Agent in all existing  Collateral  and in all
identifiable  Proceeds of such  Collateral,  which security  interest (except in
respect of  Collateral  not located at a facility  identified  on  Schedule  3.7
hereto  and motor  vehicles  for  which the  exclusive  manner of  perfecting  a
security interest therein is by noting such security interest in the certificate
of title in accordance with local law) would be prior to the claims of a trustee
in bankruptcy under Section 544(a) of the Bankruptcy Code. Continuing compliance
by the Debtor  with the  provisions  of Section  4.2 hereof will also (i) create
valid security interests in all Collateral acquired after the date hereof and in
all  identifiable  Proceeds  of such  Collateral  and (ii) cause  such  security
interests in all Collateral and in all Proceeds which are (A) identifiable  cash
Proceeds of  Collateral  covered by  financing  statements  required to be filed
hereunder,  (B)  identifiable  Proceeds  in  which a  security  interest  may be
perfected  by such  filing  under  the UCC and  (C)  any  Proceeds  in the  Cash
Collateral Account to be duly perfected under the UCC, in each case prior to the
claims of a trustee in bankruptcy  under the Bankruptcy  Code (except in respect
of Collateral not located at a facility identified on Schedule 3.5 hereto).

(b) The  security  interests  of the  Agent  in the  Collateral  located  at the
facilities identified on Schedule 3.5 hereto rank first in priority.  Other than
financing   statements  or  other  similar  documents  perfecting  the  security
interests  in favor of the  Agent,  no  financing  statements,  deeds of  trust,
mortgages or similar documents covering all or any part of the Collateral are on
file or of record in any  government  office in any  jurisdiction  in which such
filing or recording  would be  effective to perfect a security  interest in such
Collateral,  nor is any of the Collateral in the possession of any Person (other
than the Debtor) asserting any claim thereto or security interest therein.

Section 3.03.  Enforceability of Receivables and Other Intangibles.  To the best
knowledge of the Debtor,  each  Receivable  and Other  Intangible is a valid and
binding obligation of the related Account Debtor in respect thereof, enforceable
in accordance with its terms,  except as such  enforceability  may be limited by
applicable bankruptcy,  insolvency,  reorganization,  moratorium or similar laws
affecting  the  enforcement  of  creditors'  rights  generally  and  by  general
provisions of equity (regardless of whether such enforceability is considered in
a  proceeding  in equity or at law),  and  complies  with any  applicable  legal
requirements.

Section 3.04.  Place of Business.  Schedule 3.4  correctly  sets forth the chief
executive  office and principal  place of business of the Debtor and the offices
of the Debtor where records  concerning  Receivables  and Other  Intangibles are
kept.

Section 3.05.  Location of  Collateral.  Schedule 3.5  correctly  sets forth the
location of all Equipment and Inventory,  other than rolling stock, aircraft and
goods in transit.  Except as otherwise  specified in Schedule 3.5, all Inventory
and Equipment  has been located at the address  specified on Schedule 3.5 at all
times during the  four-month  period prior to the date hereof while owned by the
Debtor.  All Inventory has been and will be produced in compliance with the Fair
Labor Standards Act, 29 U.S.C.  ss.ss.  201-219,  except for such non-compliance
which could not reasonably be expected to have a material  adverse effect on the
Debtor. No Inventory is evidenced by a negotiable  document of title,  warehouse
receipt  or bill of  lading.  No  non-negotiable  document  of title,  warehouse
receipt or bill of lading has been  issued to any person  other than the Debtor,
and the Debtor has retained possession of all of such non-negotiable  documents,
warehouse receipts and bills of lading. No amount payable under or in connection
with  any  of  the  Collateral  is  evidenced  by  promissory   notes  or  other
instruments.

Section 3.06.  Trade Names.  Schedule 3.6 correctly sets forth any and all trade
names,  division  names,  assumed  names or other  names  under which the Debtor
currently  transacts  business or has transacted  business within the four-month
period prior to the date hereof.

          Section 3.07.  Patents and  Trademarks.  Schedule 3.7  correctly  sets
          forth all Patents, Patent licenses,  Trademarks and Trademark licenses
          now owned by the Debtor.

ARTICLE IV.

                                                COVENANTS

                  The Debtor covenants and agrees that until all obligations and
liabilities in respect of the Obligations  shall have performed and paid in full
and  until  no  Standby   Letters  of  Credit  are  outstanding  or  fully  cash
collateralized and the Commitments are terminated:

Section 4.01. Perfection of Security Interests. The Debtor will, at its expense,
cause all filings and recordings and other actions  specified on Schedule 4.1 to

with the following:

cause UCC financing statements and continuation statements to be filed and to be
on file in all  applicable  jurisdictions  as required  to perfect the  security
interests  granted to the Agent  hereunder,  to the extent that  applicable  law
permits perfection of a security interest by filing under the UCC;

(ii)  as to all  Proceeds,  it  will  cause  all UCC  financing  statements  and
continuation  statements  filed in accordance with clause (i) above to include a
statement or a checked box  indicating  that Proceeds of all items of Collateral
described herein are covered;

(iii) as to any amount payable under or in connection with any of the Collateral
which  shall  be or  shall  become  evidenced  by any  promissory  note or other
instrument,  the  Debtor  will  promptly  (but in no event  later  than ten (10)
Business Days after receipt of such note or instrument), pledge and deliver such
note or other  instrument to the Agent as part of the Collateral,  duly endorsed
in a manner reasonably satisfactory to the Agent;

(iv) at the request of the Agent,  the Debtor shall deliver all other Collateral
consisting  of  certificated  securities,  endorsed  for  transfer  in a  manner
reasonably  satisfactory  to the Agent (or  execute  a  securities  intermediary
account  control  agreement  to the  extent  possession  by the  Agent  of  such
securities is not feasible); and

(v) as to all Patents,  Patent licenses,  Trademarks or Trademark licenses,  the
Debtor will effect the recordation or renewal of the recordation of the security
interests of the Agent therein so as to maintain  valid and  perfected  security
interests therein under all applicable state and federal laws.

(b) Further  Assurances.  The Debtor will, from time to time and at its expense,
execute, deliver, file or record such UCC financing statements, applications for
certificates  of title  and such  other  statements,  assignments,  instruments,
documents,  agreements  or other  papers and take any other  action  that may be
necessary or desirable,  or that the Agent may reasonably  request,  in order to
create,  preserve,  perfect,  confirm or validate the  security  interest of the
Agent in the Collateral, to enable the Agent to obtain the full benefits of this
Security  Agreement  or to enable it to exercise  and enforce any of its rights,
powers and remedies hereunder,  including, without limitation, its right to take
possession of the Collateral.

(c) Signature. To the fullest extent permitted by law, the Debtor authorizes the
Agent to sign and file  financing and  continuation  statements  and  amendments
thereto with respect to the Collateral without its signature thereon.

Section 4.03. Change of Name, Identity or Structure.  The Debtor will not change
its name, identity or corporate structure in any manner and, except as set forth
on  Schedule  3.6,  will not conduct its  business  under any trade,  assumed or
fictitious  name unless it shall have given the Agent at least  forty-five  (45)
days'  prior  written  notice  thereof  and shall have taken all action (or made
arrangements to take such action  substantially  simultaneously with such change
if it is  impossible  to take such action in advance)  necessary  or  reasonably
requested  by the  Agent  to  amend  any  financing  statement  or  continuation
statement relating to the security interests granted hereby in order to preserve
such  security  interests  and to  effectuate  or maintain the priority  thereof
against all Persons.

Section 4.04.  Place of Business and Collateral.  The Debtor will not change the
location of (i) its places of business, (ii) its chief executive office or (iii)
the  office or other  locations  where it keeps or holds any  Collateral  or any
records relating thereto from the applicable  location listed on Schedule 3.4 or
3.5 unless,  prior to such change, it notifies the Agent forty-five (45) days in
advance of such change,  makes all UCC filings required by Section 4.2 and takes
all other action necessary or that the Agent may reasonably request to preserve,
perfect,  confirm and protect the security  interests granted hereby. The Debtor
will in no event  change the  location of any  Collateral  if such change  would
cause the security  interest granted hereby in such Collateral to lapse or cease
to be  perfected.  The Debtor  will at all times  maintain  its chief  executive
office within one of the forty-eight contiguous states in which Article 9 of the
uniform commercial code is in effect.

Section  4.05.  Fixtures.  The Debtor will not permit any  Equipment to become a
fixture  unless it shall  have  given the  Agent at least ten (10)  days'  prior
written  notice  thereof and shall have taken all such action and  delivered  or
caused to be delivered to the Agent all  instruments  and documents,  including,
without  limitation,  waivers and subordination  agreements by any landlords and
mortgagees, and filed all financing statements necessary or reasonably requested
by the Agent, to preserve and protect the security  interest  granted herein and
to effectuate or maintain the priority  thereof  against all Persons;  provided,
however,  that,  so long as no Event of  Default or  Potential  Event of Default
shall have  occurred  and be  continuing,  the Debtor  shall not be obligated to
comply with the provisions of this Section 4.5 with respect to the first $50,000
of Equipment (determined based on the then fair market value thereof).

Section 4.06.  Maintenance of Records.  The Debtor will keep and maintain at its
own cost and expense complete books and records relating to the Collateral which
are satisfactory to the Agent  including,  without  limitation,  a record of all
payments received and all credits granted with respect to the Collateral and all
of its other  dealings with the  Collateral.  The Debtor will mark its books and
records pertaining to the Collateral to evidence this Security Agreement and the
security interests granted hereby.  For the Agent' further security,  the Debtor
agrees  that the Agent  shall  have a special  property  interest  in all of the
Debtor's  books and records  pertaining to the  Collateral  and the Debtor shall
deliver  and  turn  over any  such  books  and  records  to the  Agent or to its
representatives at any time on demand of the Agent.

Section  4.07.  Compliance  with Laws The  Debtor  will  comply in all  material
respects with all acts, rules,  regulations,  orders,  decrees and directions of
any government or any state or local government  applicable to the Collateral or
any part  thereof or to the  operation of the  Debtor's  business  except to the
extent that the failure to comply  would not have a material  adverse  effect on
the  financial or other  condition of the Debtor;  provided,  however,  that the
Debtor may contest any act, rule, regulation,  order, decree or direction in any
reasonable  manner which shall not, in the sole opinion of the Agent,  adversely
affect the Agent's  rights or, in the case of  Collateral  located at a facility
identified on Schedule 3.7 hereto,  the first priority of its security  interest
in the Collateral.

Section 4.08. Payment of Taxes. The Debtor will pay promptly when due all taxes,
assessments and governmental charges or levies imposed upon the Collateral or in
respect of its income or  profits  therefrom,  as well as all claims of any kind
(including claims for labor, materials and supplies), except that no such charge
need be paid if (i) the  validity  thereof is being  contested  in good faith by
appropriate  proceedings and (ii) such charge is adequately  reserved against in
accordance  with  generally  accepted  accounting  principles,  as  consistently
applied.

Section 4.09.  Compliance with Terms of Accounts and Contracts.  The Debtor will
perform and comply in all material  respects with all of its  obligations  under
all agreements  relating to the Collateral to which it is a party or by which it
is bound.

Section  4.10.  Limitation on Liens on  Collateral.  The Debtor will not create,
permit or suffer to exist,  and will  defend  the  Collateral  and the  Debtor's
rights with respect  thereto  against and take such other action as is necessary
to  remove  any  Lien,  security  interest,  encumbrance,  or claim in or to the
Collateral other than the security interests created hereunder and such Liens to
the  extent  permitted  pursuant  to  Section  6.2(a)  of the  Revolving  Credit
Agreement.

Section 4.11. Limitations on Modifications of Receivables and Other Intangibles;
No Waivers or Extensions.  The Debtor will not (i) amend,  modify,  terminate or
waive any  provisions  of any material  Receivable  or Other  Intangible  in any
manner which might, when taken together with all such other Receivables or Other
Intangibles,  respectively,  materially  reduce the value of all  Receivables or
Other  Intangibles,  respectively,  in the  Collateral,  (ii)  fail to  exercise
promptly and  diligently  each and every  material right which it may have under
each  Receivable  and Other  Intangible  or (iii) fail to deliver to the Agent a
copy of each material demand,  notice or document received by it relating in any
way to any Receivable or Other Intangible.

Section  4.12.   Maintenance  of  Insurance.   The  Debtor  will  maintain  with
financially   sound  insurance   companies   licensed  to  do  business  in  the
jurisdictions  in which the  Collateral  is located  insurance  policies  on the
Inventory and Equipment in accordance  with the  provisions of Section 6.1(m) of
the Revolving Credit Agreement.

Section 4.13.  Limitations on  Dispositions  of Collateral.  The Debtor will not
directly or indirectly (through the sale of stock, merger or otherwise), without
the prior  written  consent of the Agent,  sell,  transfer,  lease or  otherwise
dispose of any of the Collateral,  or attempt, offer or contract to do so except
for (i) sales of Inventory in the ordinary course of its business for fair value

Potential  Event of Default) has occurred and is continuing,  dispositions  in a
commercially reasonable manner of Equipment which has become redundant, worn out
or obsolete or which should be replaced so as to improve  productivity,  so long
as the  proceeds  of any such  disposition  are (x) used to acquire  replacement
equipment  which has comparable or better utility and equivalent or better value
and which is subject to a first priority security interest in favor of the Agent
therein,  except  as  permitted  by  Section  6.2(a)  of  the  Revolving  Credit
Agreement, or (y) applied to repay the Obligations. The inclusion of Proceeds of
the Collateral under the security interests granted hereby shall not be deemed a
consent by the Agent to any sale or disposition of any Collateral  other than as
permitted by this Section 4.13.

Section 4.14. Further  Identification of Collateral.  The Debtor will furnish to
the Agent from time to time  statements and schedules  further  identifying  and
describing  the  Collateral  and  such  other  reports  in  connection  with the
Collateral as the Agent may reasonably request. The Debtor shall promptly notify
the Agent if the value of the Collateral located at the facilities identified on
Schedule 3.7 hereto is less than 80% of the value of all of the Collateral.

Section  4.15.  Notices.  The  Debtor  will  advise  the Agent  promptly  and in
reasonable detail (i) of any Lien, security interest,  encumbrance or claim made
or  asserted  against  any of the  Collateral,  other  than,  unless  reasonably
requested  by the Agent,  Liens  permitted  by Section  6.2(a) of the  Revolving
Credit  Agreement,  (ii)  of  any  material  change  in the  composition  of the
Collateral,  and (iii) of the  occurrence  of any other event which would have a
material  adverse  effect on the  aggregate  value of the  Collateral  or on the
security interests granted to the Agent in this Security Agreement.

Section 4.16.  Change of Law. The Debtor shall promptly  notify the Agent of any
change in law known to it which (i) adversely  affects or will adversely  affect
the validity,  perfection or priority of the security  interests granted hereby,
(ii)  requires  or will  require a change in the  proceedings  to be followed in
order to maintain and protect such  validity,  perfection  and priority or (iii)
could result in the Agent not having a perfected security interest in any of the
Collateral.

(a) Access to Books and Records. The Debtor shall,  following any request by the
Agent and upon reasonable  notice,  permit the Agent or its  representatives  to

as the Agent may deem reasonably  necessary,  and the Debtor agrees to render to
the Agent, at the Debtor's cost and expense,  such clerical and other assistance
as  may  be  reasonably  requested  with  regard  thereto.  The  Agent  and  its
representatives  shall upon  reasonable  notice and during normal business hours
also  have the  right to enter  into  and  upon any  premises  where  any of the
Inventory or the  Equipment is located for the purpose of  inspecting  the same,
observing its use or protecting the interests of the Agent therein.

(b)  Audits.  The  Debtor  shall  permit  the  Lenders,   the  Agent  and  their
representatives  and advisors to review the operations of the Debtor and perform
the audits and  examinations  as  provided  in Section  6.1(l) of the  Revolving
Credit Agreement.

          Section  4.18.  Maintenance  of  Equipment.  The Debtor  will,  at its
          expense, maintain the Equipment in good operating condition,  ordinary
          wear and tear excepted.

Section 4.19.     Covenants Regarding Patent and Trademark Collateral.

(c)  Generally.  At  such  time as the  Debtor  shall  acquire  any  Patents  or
Trademarks,  it will comply with the terms,  covenants  and  warranties  of this
Section 4.19.

(d) Continued Use of Trademark.  The Debtor (either itself or through licensees)
will, unless the Debtor shall reasonably determine,  after consultation with the
Agent,  that a Trademark  is of  negligible  economic  value to the Debtor,  (i)
continue  to use each  Trademark  on each  and  every  Trademark  class of goods
applicable  to its current  products  and  services as  reflected in its current
catalogs,  brochures and price lists in order to maintain each Trademark in full
force and free from any claim of  abandonment  for non-use,  (ii) maintain as in
the past the quality of products  and  services  offered  under each  Trademark,
(iii) employ each Trademark with the appropriate  notice of  registration,  (iv)
not adopt or use any mark which is confusingly  similar to a colorable imitation
of any Trademark and (v) not (and not permit any licensee or sublicensee thereof
to) do any act or knowingly  omit to do any act whereby any Trademark may become
invalidated.

(e) No  Abandonment.  The Debtor will not,  unless the Debtor  shall  reasonably
determine,  after  consultation  with the Agent,  that a Patent is of negligible
economic  value to the  Debtor,  do any act,  or  knowingly  omit to do any act,
whereby any Patent may be abandoned or dedicated.

(f) Notice of Abandonment or Adverse Determinations. The Debtor shall notify the
Agent  immediately if it knows,  or has reason to know,  that any application or
registration  relating  to any  Patent or  Trademark  may  become  abandoned  or
dedicated,  or of any adverse determination or development  (including,  without
limitation,  the institution of, or any such determination or development in any
proceeding  in the United  States  Patent and  Trademark  Office or any court of
tribunal in any  country)  regarding  the  Debtor's  ownership  of any Patent or
Trademark, its right to register the same or keep and maintain the same.

(g) Filings After Notice to Agent.  In no event shall the Debtor,  either itself
or through any agent,  employee,  licensee or designee,  file an application for
registration  of any  Patent or  Trademark  with the  United  States  Patent and
Trademark  Office or any  similar  office or agency in any other  country or any
political  subdivision  thereof,  unless it promptly informs the Agent and, upon
request of the Agent, executes and delivers any and all agreements, instruments,
documents  and papers as the Agent may request to evidence the Agent's  security
interest in such Patent or Trademark and the goodwill and general intangibles of
the  Debtor  relating  thereto or  represented  thereby,  and the Debtor  hereby
constitutes the Agent its attorney-in-fact to execute and file all such writings
for the foregoing purposes, all such acts of such attorney being hereby ratified
and confirmed.

(h) Pursuit of Applications  and Maintenance of  Registrations.  The Debtor will
take all necessary  steps,  including,  without  limitation,  in any  proceeding
before the United States Patent and  Trademark  Office or any similar  office or
agency in any other country or any political  subdivision  thereof,  to maintain
and pursue each  application  (and to obtain the relevant  registration)  and to
maintain each  registration  of the Patents and  Trademarks,  including  without
limitation, filing of applications for renewal, affidavits of use and affidavits
of incontestability;  provided,  however, that no such Patent or Trademark shall
be required to be  maintained  or pursued to the extent such Patent or Trademark
is  determined  by the  Debtor,  after  consultation  with the  Agent,  to be of
negligible economic value to the Debtor.

(i) Notice of  Infringement.  If any of the Patent and  Trademark  Collateral is
infringed,  misappropriated  or  diluted  by a third  party,  the  Debtor  shall
promptly  notify the Agent after it learns thereof and shall,  unless the Debtor
shall reasonably determine,  after consultation with the Agent, that such Patent
and Trademark Collateral is of negligible economic value to the Debtor, promptly
sue for infringement, misappropriation of dilution, seek injunctive relief where
appropriate   and  recover   any  and  all   damages   for  such   infringement,
misappropriation  or  dilution,  or take such other  action as the Debtor  shall
reasonably deem appropriate  under the  circumstances to protect such Patent and
Trademark Collateral.

Section 4.20.  Termination  of Federal  Contracts.  With respect to each Federal
Contract in respect of which the Debtor is required to execute an  Assignment of
Federal  Contract in accordance with Section 4.21 hereof,  the Debtor shall give
prompt written  notice to the Agent if the U.S.  Government  shall  terminate or
threaten to  terminate  (whether  for  convenience  or default) any such Federal
Contract  with the Debtor  having a value  (including  unexercised  options)  of
$100,000 or more. In addition,  the Debtor shall give prompt  written  notice to
the Agent if the U.S.  Government  shall  terminate or threaten to terminate any
contract between the U.S.  Government and any other prime contractor under which
the  Debtor  is a  subcontractor  if the  value of such  subcontract  (including
unexercised options) is $100,000 or more.

Section 4.21. Federal Contracts.  The Debtor shall provide to the Agent, as soon
as reasonably  practicable but not later than forty-five (45) days following the
end of each Fiscal Quarter,  a report identifying each Federal Contract to which
it is a party,  having  attached  thereto  a copy of the first two pages of such
Federal  Contract  and any  amendment  thereto,  to the  extent  not  previously
provided to the Agent.  At the request of the Agent  (unless an Event of Default
shall have  occurred and be  continuing,  in which case no such request shall be
required),  the Debtor shall  execute and deliver to the Agent an  Assignment of
Federal Contract, in substantially the form of Exhibit A hereto (the "Assignment
of Federal Contract"), and execute any other instruments or take any other steps
required  by the Agent in order  that all moneys due or to become due under such
Federal  Contracts shall be assigned to the Agent and notice thereof given under
the Assignment of Claims Act, including without  limitation  delivery of Notices
of Assignments with respect to each Federal Contract as contemplated by Appendix
A to Exhibit A hereto.

Section 4.22.  Reimbursement  Obligation.  Should the Debtor fail to comply with
the provisions of this Security Agreement, the Revolving Credit Agreement or any
other agreement relating to the Collateral such that the value of any Collateral
or the validity,  perfection,  rank or value of any security interest granted to
the  Agent  hereunder  or  thereunder  is  thereby   diminished  or  potentially
diminished or put at risk (as reasonably  determined by the Agent), the Agent on
behalf of the Debtor may, but shall not be required to,  effect such  compliance
on behalf of the Debtor,  and the Debtor shall  reimburse the Agent for the cost
thereof on demand,  and interest shall accrue on such  reimbursement  obligation
from the date the relevant  costs are incurred  until  reimbursement  thereof in
full at the Default Rate.

ARTICLE V.

                                      REMEDIES; RIGHTS UPON DEFAULT

Section 5.01. UCC Rights.  In the event that any portion of the  Obligations has
been declared or becomes due and payable in accordance with the Revolving Credit
Agreement or other Credit  Documents and such  Obligations have not been paid in
full,  the Agent may in addition to all other rights and remedies  granted to it
in this Security  Agreement and in any other  instrument or agreement  securing,
guarantying,  evidencing or relating to the Obligations, exercise (i) all rights
and  remedies of a secured  party under the UCC (whether or not in effect in the
jurisdiction  where  such  rights  are  exercised)  and  (ii) all  other  rights
available to the Agent at law or in equity.

          Section 5.02.  Payments on Collateral.  Without limiting the rights of
          the Agent under any other provision of this Security Agreement,  if an
          Event of Default shall occur and be continuing:

(i) all payments  received by the Debtor under or in connection  with any of the
Collateral  shall  be held by the  Debtor  in  trust  for the  Agent,  shall  be
segregated  from other funds of the Debtor and shall  forthwith  upon receipt by
the Debtor be turned  over to the  Agent,  in the same form as  received  by the
Debtor  (duly  indorsed  by the  Debtor  to the  Agent,  if  required  to permit
collection thereof by the Agent); and

(ii) all such  payments  received  by the  Agent  (whether  from the  Debtor  or
otherwise)  may, in the sole  discretion  of the Agent,  be held by the Agent as
collateral  security for, and/or then or at any time thereafter applied in whole
or in part by the Agent to the payment of, the expenses and the  Obligations  as
set forth in Section 5.11 hereof.

Section 5.03.  Possession of Collateral.  In  furtherance of the foregoing,  the
Debtor  expressly  agrees  that,  if an  Event of  Default  shall  occur  and be
continuing, the Agent may (i) by judicial powers, or without judicial process if
it can be done without breach of the peace, enter any premises where any of such
Collateral is or may be located and,  without  charge or liability to the Agent,
seize and remove such  Collateral from such premises and (ii) have access to and
use of the Debtor's books and records relating to such Collateral.

Section 5.04.     Sale of Collateral; Notice.

(a) Sale of Collateral.  The Debtor expressly agrees that if an Event of Default
shall occur and be continuing, the Agent, without demand of performance or other
demand or notice of any kind (except the notice  specified below of the time and
place of any public or private  sale) to or upon the Debtor or any other  Person
(all of which  demands  and/or  notices are hereby  waived by the  Debtor),  may
forthwith (i) apply the cash, if any, then held by it as collateral as specified
in Section  5.11 hereof and (ii) if there shall be no cash or such cash shall be
insufficient to pay the Obligations in full, collect,  receive,  appropriate and
realize upon the Collateral,  and/or sell, assign,  give an option or options to
purchase or otherwise  dispose of and deliver the  Collateral (or contract to do
so) or any part thereof in one or more parcels (which need not be in round lots)
at public or  private  sale,  at any  office of the Agent or  elsewhere  in such
manner as is  commercially  reasonable and, as the Agent may deem best, for cash
or on credit or for future delivery  without  assumption of any credit risk. The
Agent shall have the right upon any such public sale,  and, if the Collateral is
of a type customarily  sold in a recognized  market or is of a type which is the
subject of widely distributed  standard price quotations,  upon any such private
sale or sales,  to purchase the whole or any part of the Collateral so sold, and
thereafter to hold the same,  absolutely and free from any right or claim of any
kind. To the extent  permitted by applicable  law, the Debtor waives all claims,
damages  and  demands  against  the  Agent  arising  out  of  the   foreclosure,
repossession, retention or sale of the Collateral.

(b) Notice of Sale. Unless the Collateral threatens to decline speedily in value
or is of a type  customarily sold on a recognized  market,  the Agent shall give
the Debtor  ten (10)  days'  written  notice of its  intention  to make any such
public or private sale or sale at a broker's board or on a securities  exchange.
Such  notice  shall (i) in the case of a public  sale,  state the time and place
fixed  for  such  sale,  (ii) in the  case of sale at a  broker's  board or on a
securities  exchange,  state the board or  exchange  at which such sale is to be
made and the day on which the  Collateral,  or the portion  thereof  being sold,
will first be offered  for sale and (iii) in the case of a private  sale,  state
the day after which such sale may be consummated.  The Agent shall not obligated
to make any such sale  pursuant  to any such  notice.  The Agent may adjourn any
public or private  sale or cause the same to be  adjourned  from time to time by
announcement at the time and place fixed for the sale, and such sale may be made
at any time or place to which the same may be so  adjourned.  In the case of any
sale of all or any part of the Collateral on credit or for future delivery,  the
Collateral  so sold may be retained by the Agent until the selling price is paid
by the purchaser thereof, but the Agent shall not incur any liability in case of
the failure of such purchase to take up and pay for the  Collateral so sold and,
in the case of such failure, such Collateral may again be sold upon like notice.

(c) Special  Provisions  Relating to Sales of Securities.  The Debtor recognizes
that  the  Agent  may be  unable  to  effect  a  public  sale  of any or all the
Collateral  constituting a "security" (as such term is defined in the Securities
Act) by reason of  certain  prohibitions  contained  in the  Securities  Act and
applicable state securities laws or otherwise, and may be compelled to resort to
one or more private sales thereof to a restricted  group of purchasers that will
be obliged to agree,  among other things,  to acquire such  securities for their
own account for  investment  and not with a view to the  distribution  or resale
thereof.  The Debtor  acknowledges  and agrees  that any such  private  sale may
result in prices and other terms less  favorable than if such sale were a public
sale and, notwithstanding such circumstances,  agrees that any such private sale
shall be deemed to have been made in a commercially reasonable manner. The Agent
shall be under no obligation to delay a sale of any of Collateral constituting a
security  for the  period of time  necessary  to permit  the  issuer  thereof to
register  such  securities  for public sale under the  Securities  Act, or under
applicable state securities laws, even if such issuer would agree to do so.

Section 5.05.  Rights of Purchasers.  Upon any sale of the  Collateral  (whether
public or  private),  the Agent  shall  have the right to  deliver,  assign  and
transfer  to the  purchaser  thereof  the  Collateral  so sold.  Each  purchaser
(including  the  Agent)  at any such  sale  shall  hold the  Collateral  so sold
absolutely,  free from any claim or right of whatever kind, including any equity
or right of redemption of the Debtor who, to the extent permitted by law, hereby
specifically waives all rights of redemption, including, without limitation, any
right to redeem the Collateral  under Section 9-506 of the UCC, and any right to
a judicial or other stay or approval  which it has or may have under any law now
existing or hereafter adopted.

Section 5.06.     Additional Rights of the Agent.

(a) Right to Maintain Proceedings.  The Agent (i) shall have the right and power
to institute and maintain such suits and proceedings as it may deem  appropriate
to protect and enforce the rights  vested in it by this  Security  Agreement and
(ii) may proceed by suit or suits at law or in equity to enforce such rights and
to foreclose  upon the  Collateral and to sell all or, from time to time, any of
the   Collateral   under  the  judgment  or  decree  of  a  court  of  competent
jurisdiction.

(b)  Appointment  of  Receiver.  The Agent  shall,  to the extent  permitted  by
applicable law,  without notice to the Debtor to any party claiming  through the
Debtor,  without regard to the solvency or insolvency at such time of any Person
then liable for the  payment of any of the  Obligations,  without  regard to the
then value of the Collateral and without requiring any bond from any complainant
in such  proceedings,  be entitled as a matter of right to the  appointment of a
receiver  or  receivers  (who may be the  Agent) of the  Collateral  or any part
thereof,  pending  such  proceedings,  with such powers as the court making such
appointment  shall  confer,  and to the  entry  of an order  directing  that the
profits, revenues and other income of the property constituting the whole or any
part of the Collateral be segregated,  sequestered and impounded for the benefit
of the Agent,  and the Debtor  irrevocably  consents to the  appointment of such
receiver or receivers and to the entry of such order.

(c) No Duty to  Exercise  Rights.  In no event  shall the Agent have any duty to
exercise any rights or take any steps to preserve the rights of the Agent in the
Collateral,  nor shall the Agent be liable to the Debtor or any other Person for
any loss caused by the Agent's failure to meet any obligation imposed by Section
9-207 of the UCC or any successor provision. Without limiting the foregoing, the
Agent  shall be deemed to have  exercised  reasonable  care in the  custody  and
preservation  of the  Collateral in its possession if the Collateral is accorded
treatment  substantially equal to that which the Agent accords its own property,
it being understood that the Agent shall not have any duty or responsibility for
(i) ascertaining or taking action with respect to calls, conversions, exchanges,
maturities,  tenders or other matters relative to any Collateral, whether or not
the Agent has or is deemed to have knowledge of such matters, or (ii) taking any
necessary  steps to preserve  rights  against any  parties  with  respect to any
Collateral.

Section 5.07.     Remedies Not Exclusive, etc.

(a) Remedies Not Exclusive. No remedy conferred upon or reserved to the Agent in
this  Security  Agreement  is intended to be  exclusive  of any other  remedy or
remedies,  but every such remedy shall be cumulative and shall be in addition to
every other  remedy  conferred  herein or now or  hereafter  existing at law, in
equity or by statute.

(b)  Restoration  of Rights.  If the Agent shall have  proceeded  to enforce any
right,  remedy or power under this Security Agreement and the proceeding for the
enforcement  thereof shall have been discontinued or abandoned for any reason or
shall have been  determined  adversely  to the  Agent,  the Debtor and the Agent
shall,   subject  to  any  determination  in  such  proceeding,   severally  and
respectively  be  restored  to their  former  positions  and  rights  under this
Security Agreement,  and thereafter all rights, remedies and powers of the Agent
shall continue as though no such proceedings had been taken.

(c)  Enforcement.  All rights of action  under this  Security  Agreement  may be
enforced by the Agent without the  possession of any  instrument  evidencing any
Obligation or the production  thereof at any trial or other proceeding  relative
thereto, and any suit or proceeding  instituted by the Agent shall be brought in
its name and any judgment shall be held as part of the Collateral.

Section 5.08.     Waiver and Estoppel.

(a) No Actions to Impede Sale of Collateral. The Debtor agrees, to the extent it
may lawfully do so, that it will not at any time in any manner  whatsoever claim
or take the benefit or advantage of any appraisal,  valuation,  stay, extension,
moratorium,  turnover or redemption  law, or any law permitting it to direct the
order in which the  Collateral  shall be sold,  now or at any time  hereafter in
force  which  may  delay,   prevent  or  otherwise  affect  the  performance  or
enforcement  of this  Security  Agreement,  and  hereby  waives  all  benefit or
advantage of all such laws. The Debtor covenants that it will not hinder,  delay
or impede  the  execution  of any power  granted  to the Agent in this  Security
Agreement, any Assignment of Federal Contract or any other Credit Document.

(b) Collateral Sold As An Entirety. The Debtor, to the extent it may lawfully do
so, on behalf of itself and all who claim through or under it, including without
limitation any and all  subsequent  creditors,  vendees,  assignees and lienors,
waives  and  releases  all  rights to demand or to have any  marshalling  of the
Collateral upon any sale, whether made under any power of sale granted herein or
pursuant to judicial  proceedings or under any foreclosure or any enforcement of
this Security Agreement,  and consents and agrees that all of the Collateral may
at any such sale be offered and sold as an entirety.

(c) Waiver of  Notices.  The Debtor  waives,  to the  extent  permitted  by law,
presentment,  demand,  protest  and any notice of any kind  (except  the notices
expressly required hereunder) in connection with this Security Agreement and any
action taken by the Agent with respect to the Collateral.

Section 5.09.     Power of Attorney; Powers Coupled With An Interest.

(a) Power of Attorney.  Without limiting any other right granted hereunder,  the
Debtor hereby irrevocably constitutes and appoints the Agent, with full power of
substitution,  as its true and  lawful  attorney-in-fact  with full  irrevocable
power and  authority in the place and stead of the Debtor and in the name of the
Debtor  or in its  own  name,  from  time  to  time  in the  Agent's  reasonable
discretion,  for the  purpose  of  carrying  out  the  terms  of  this  Security
Agreement,  to take any and all  appropriate  action and to execute  any and all
documents and instruments  which may be necessary or desirable to accomplish the
purpose of this Security  Agreement and,  without limiting the generality of the
foregoing,  hereby gives the Agent the power and right, on behalf of the Debtor,
without notice to or assent by the Debtor, to do the following:

          (i) to pay or  discharge  taxes,  liens,  security  interests or other
          encumbrances levied or placed on or threatened against the Collateral;

(ii) to effect  any  repairs  or any  insurance  called for by the terms of this
Security  Agreement or any other Credit Document,  and to pay all or any part of
the premiums therefor and the costs thereof;

(iii) upon the occurrence and  continuance of any Event of Default and otherwise
to the  extent  provided  in this  Security  Agreement,  (A) to direct any party
liable for any payment  under any of the  Collateral  to make payment of any and
all moneys due and to come due thereunder  directly to the Agent or as the Agent
shall direct,  (B) to receive  payment of and receipt for, and to demand and sue
for, any and all moneys,  claims and other  amounts due and to become due at any
time in respect of or arising out of the Collateral, (C) to sign and indorse and
receive,  take, assign and deliver, any checks,  notes,  drafts,  negotiable and
non-negotiable  instruments,  any invoices,  freight or express bills,  bills of
lading,  storage or warehouse  receipts,  drafts against  debtors,  assignments,
verifications  and  notices in  connection  with  accounts  and other  documents
relating to the  Collateral,  (D) to  commence,  settle,  compromise,  compound,
prosecute,  defend or adjust any claim,  suit, action or proceeding with respect
to, or in connection  with, the  Collateral,  (E) to sell,  transfer,  assign or
otherwise  deal in or with the  Collateral  or any part  thereof,  as fully  and
effectively  as if the Agent were the absolute  owner  thereof and (F) to do, at
its option,  but at the expense of the Debtor, at any time or from time to time,
all acts and things  which the Agent deems  necessary  to  protect,  preserve or
realize upon the Collateral and the Agent's security interest therein,  in order
to effect the intent of this Security Agreement, all as fully and effectively as
the Debtor might do.

(b) Powers Coupled With an Interest.  All authorizations and agencies granted or
provided  herein with respect to the  Collateral,  including the powers  granted
under clause (a) of this Section 5.9, are irrevocable and powers coupled with an
interest.

Section 5.10. Certain Provisions Relating to Securities.  Solely with respect to
any Collateral  constituting a "security" (as defined in the Securities Act), if
an Event of Default shall have occurred and be continuing,  all such  securities
(as defined in the Securities Act)  constituting a part of the Collateral shall,
at the  request  of the  Agent,  be  registered  in the name of the Agent or its
nominee,  and the Agent or its nominee may  thereafter  exercise (i) all voting,
corporate and other rights,  powers and privileges pertaining to such Collateral
at any meeting of shareholders of the issuer thereof or otherwise,  and (ii) any
and all  rights of  conversion,  exchange,  subscription  and any other  rights,
privileges or options  pertaining to such  Collateral as if it were the absolute
owner  thereof  (including,  without  limitation,  the right to  exchange at its
discretion  any  and  all  such  Collateral  upon  the  merger,   consolidation,
reorganization, recapitalization or other fundamental change in the structure of
any such  issuer,  or upon the exercise by the Debtor or the Agent of any right,
privilege or option pertaining to such Collateral,  and in connection therewith,
the right to deposit and deliver any and all such Collateral with any committee,
depositary, transfer agent, registrar or other designated agency upon such terms
and conditions as it may determine), all without liability except to account for
property  actually  received  by it and except as  provided  in  Section  5.6(c)
hereof,  but the Agent  shall  have no duty to the Debtor to  exercise  any such
right, privilege or option and shall not be responsible for any failure to do so
or delay in so doing.

          Section 5.11.  Application of Monies.  The proceeds of any sale of, or
          other  realization  upon, all or any part of the  Collateral  shall be
          applied by the Agent in the following order of priority:

                  first,  to  payment  of the  expenses  of such  sale or  other
realization,  including reasonable  compensation to the Agent and its agents and
counsel,  and all  expenses,  liabilities  and advances  incurred or made by the
Agent, its agents and counsel in connection  therewith or in connection with the
care, safekeeping or otherwise of any or all of the Collateral;

          second, to payment of the Obligations,  in such order as the Agent may
          elect; and

                  third, any surplus then remaining shall be paid to the Debtor,
or its  successors  or assigns,  or to  whomsoever  may be lawfully  entitled to
receive the same (including  pursuant to Section 9-504(1)(C) of the UCC) or as a
court of competent jurisdiction may direct.

ARTICLE VI.

                                              MISCELLANEOUS

Section 6.01. Notices. All notices, requests and other communications to a party
hereunder  shall be in writing  and shall be given to such party at its  address
set forth on the  signature  page hereof or such other address as such party may
hereafter  specify for that  purpose by notice to the other.  Each such  notice,
request or other  communication shall be effective (i) in the case of telephonic
notice (to the extent  expressly  permitted  hereunder),  when made, (ii) in the
case of notice delivered by overnight  express  courier,  one Business Day after
the Business Day such notice was delivered to such courier, (iii) in the case of
notice  delivered by first class mail, three Business Days after being deposited
in the mail,  postage  prepaid,  return receipt  requested,  (iv) in the case of
notice by hand,  when  delivered,  or (v) in the case of notice by any customary
means of telecommunication, when sent provided confirmation of receipt or answer
back has been  received,  in each  case if  addressed  to any  party  hereto  as
provided  herein.  Rejection or refusal to accept,  or the  inability to deliver
because of a changed address of which no notice was given,  shall not affect the
validity of notice given in accordance with this section.

Section 6.02.  No Waiver;  Cumulative  Remedies.  The Agent shall not by any act
(except by a written  instrument  pursuant  to Section  6.3 hereof) be deemed to
have waived any right or remedy hereunder. No failure to exercise, nor any delay
in exercising,  on the part of the Agent any right, power or privilege hereunder
shall operate as a waiver thereof.  No single or partial  exercise of any right,
power or  privilege  hereunder  shall  preclude  any other or  further  exercise
thereof or the exercise of any other right, power or privilege.  A waiver by the
Agent  of any  right  or  remedy  hereunder  on any one  occasion  shall  not be
construed as a bar to any right or remedy which the Agent would  otherwise  have
on any future occasion.  The rights and remedies herein provided are cumulative,
may be  exercised  singly or  concurrently  and are not  exclusive  of any other
rights or remedies provided by law.

Section 6.03.  Amendments  and Waivers.  None of the terms or provisions of this
Security Agreement may be amended,  supplemented or otherwise modified except by
a written  instrument  executed by the Debtor and the Agent;  provided  that any
provision of this  Security  Agreement may be waived by the Agent in a letter or
agreement  executed by the Agent or by telex or facsimile  transmission from the
Agent.

Section 6.04.  Successors and Assigns. The provisions of this Security Agreement
shall be binding  upon and inure to the benefit of the parties  hereto and their
respective  successors and assigns;  provided,  however, that the Debtor may not
assign or transfer any of its rights or obligations  hereunder without the prior
written consent of the Agent.

          Section 6.05. Governing Law. THIS SECURITY AGREEMENT SHALL BE GOVERNED
          BY AND CONSTRUED IN ACCORDANCE  WITH THE LAWS OF THE  COMMONWEALTH  OF
          VIRGINIA,  OTHER  THAN ITS LAWS  RESPECTING  CHOICE OF LAW OTHER  THAN
          THOSE CONTAINED IN THE UCC.

Section 6.06.     Limitation by Law; Severability.

(a) All rights,  remedies and powers provided in this Security  Agreement may be
exercised  only to the extent  that the  exercise  thereof  does not violate any
applicable  provision of law, and all the provisions of this Security  Agreement
are intended to be subject to all applicable  mandatory  provisions of law which
may be controlling  and to be limited to the extent  necessary so that they will
not render this Security Agreement  invalid,  unenforceable in whole or in part,
or not entitled to be recorded,  registered or filed upon the  provisions of any
applicable law.

(b) If any provision hereof is invalid and  unenforceable  in any  jurisdiction,
then, to the fullest extent  permitted by law, (i) the other  provisions  hereof
shall  remain  in full  force  and  effect  in such  jurisdiction  and  shall be
liberally  construed in favor of the Agent in order to carry out the  intentions
of the parties  hereto as nearly as may be possible and (ii) the  invalidity  or
unenforceability  of any provision hereof in any  jurisdiction  shall not affect
the validity or enforceability of such provision in any other jurisdiction.

Section  6.07.  Counterparts.  This  Security  Agreement  may be executed in any
number of counterparts and by different parties hereto on separate counterparts,
each complete set of which, when so executed and delivered by all parties, shall
be an original,  but all such counterparts shall together constitute but one and
the same instrument.

Section 6.08. Expenses of the Agent. The Debtor shall pay to the Agent from time
to time upon demand,  all of the costs and expenses incurred by the Agent or any
Lender (including,  without limitation, the reasonable fees and disbursements of
counsel  and any  amounts  payable  by the  Agent or any  Lender to any of their
respective   agents)  (i)  arising  in  connection   with  the   administration,
modification, amendment, waiver or termination of this Security Agreement or any
document or agreement  contemplated hereby or any consent or waiver hereunder or
thereunder  or (ii)  incurred  in  connection  with the  administration  of this
Security  Agreement,  or any document or agreement  contemplated  hereby,  or in
connection  with the  administration,  sale or other  disposition  of Collateral
hereunder  or  under  any  document  or  agreement  contemplated  hereby  or the
preservation,  protection or defense of the rights of the Agent or any Lender in
and to the Collateral.

Section  6.09.  Indemnification.   The  Debtor  shall  at  all  times  hereafter
indemnify, hold harmless and, on demand, reimburse the Agent and the Lenders and
their  respective  subsidiaries,   affiliates,  successors,  assigns,  officers,
directors,   employees  and  agents,  and  their  respective  heirs,  executors,
administrators, successors and assigns (all of the foregoing parties, including,
but not limited to, the Agent, being hereinafter collectively referred to as the
"Indemnities" and individually as an "Indemnitee") from, against and for any and
all liabilities,  obligations,  claims, damages, actions,  penalties,  causes of
action, losses, judgments, suits, costs, expenses and disbursements,  including,
without  limitation,  attorney's  fees  (any  and  all  of the  foregoing  being
hereinafter  collectively referred to as the "Liabilities" and individually as a
"Liability")  which  the  Indemnitees,  or  any  of  them,  might  be or  become
subjected, by reason of, or arising out of the preparation, execution, delivery,
modification,  administration  or enforcement  of, or performance of the Agent's
rights  under,  this  Security  Agreement or any other  document,  instrument or
agreement  contemplated  hereby or executed in  connection  herewith;  provided,
however, that the Debtor shall not be liable to any Indemnitee for any Liability
caused solely by the gross negligence or willful  misconduct of such Indemnitee.
In no event shall any  Indemnitee,  as a condition to enforcing its rights under
this Section 6.9 or  otherwise,  be obligated to make a claim  against any other
Person (including,  without  limitation,  the Agent) to enforce its rights under
this Section 6.9.

Section 6.10.  Termination;  Survival.  This Security  Agreement shall terminate
when the security interests granted hereunder have terminated and the Collateral
has been  released as  provided  in Section  2.6;  provided,  however,  that the
obligations  of the Debtor under Section 4.22 and the provisions of this Article
6 shall survive any such termination.

Section  6.11.  Judicial  Proceedings;   Waiver  of  Jury  Trial.  Any  judicial
proceeding  brought  against  the Debtor  with  respect to any Credit  Agreement
Related  Claim hereby may be brought in any court of competent  jurisdiction  in
the  Commonwealth  of Virginia,  County of Fairfax,  or any Federal court in the
Eastern  District of Virginia,  and, by execution  and delivery of this Security
Agreement,   the  Debtor  (a)  accepts,   generally  and  unconditionally,   the
nonexclusive  jurisdiction  of such courts and any related  appellate  court and
irrevocably  agrees to be bound by any judgment  rendered  thereby in connection
with any Credit Agreement Related Claim and (b) irrevocably waives any objection
it may now or hereafter have as to the venue of any such  proceeding  brought in
such a court or that such a court is an  inconvenient  forum.  The Debtor hereby
waives personal  service of process and consents that service of process upon it
may be made by certified or registered mail,  return receipt  requested,  at its
address specified or determined in accordance with the provisions of Section 6.1
hereof,  and service so made shall be deemed completed on the earlier of (x) the
receipt  thereof and (y) if sent by registered or certified mail (return receipt
requested),  the fifth (5th) Business Day after such service is deposited in the
mail. Nothing herein shall affect the right of the Agent to serve process in any
other  manner  permitted  by law or shall  limit the right of the Agent to bring
proceedings  against  the  Debtor in the courts of any other  jurisdiction.  Any
judicial proceeding by the Debtor against the Agent relating to or involving any
Credit  Agreement  Related Claim hereby shall be brought only in a court located
in the Commonwealth of Virginia,  County of Fairfax, or the Federal court in the
Eastern  District of Virginia.  THE DEBTOR AND THE AGENT HEREBY  UNCONDITIONALLY
WAIVE  TRIAL  BY JURY IN ANY  JUDICIAL  PROCEEDING  TO WHICH  THEY  ARE  PARTIES
INVOLVING ANY CREDIT AGREEMENT RELATED CLAIM.

Section  6.12.  Integration.  This  Security  Agreement  and  the  other  Credit
Documents  constitute  the entire  agreement  of the  Agent,  the  Lenders,  the
Borrower and the other Credit  Parties with respect to the subject matter hereof
and  thereof,  and  there  are no  promises,  undertakings,  representations  or
warranties by the Agent or any Lender  relative to the subject  matter hereof or
thereof not  expressly  set forth or  referred to herein or in the other  Credit
Documents.

responsibilities  of the Agent under this Security Agreement with respect to any
action  taken by the Agent or the exercise or  non-exercise  by the Agent of any
option,  voting right,  request,  judgment or other right or remedy provided for
herein or resulting or arising out of this Security  Agreement shall, as between
the Agent and the Lenders,  be governed by the Revolving Credit Agreement and by
such other  agreements with respect thereto as may exist from time to time among
them, but, as between the Agent and the Debtor,  the Agent shall be conclusively
presumed to be acting as agent for the Lenders with full and valid  authority so
to act or refrain from acting, and the Debtor shall not be under any obligation,
or entitlement, to make any inquiry respecting such authority.

Section 6.14. Headings,  Bold Type and Table of Contents.  The section headings,

                  WHEREAS,   the  Assignor  has  secured   certain   obligations
undertaken  by Hagler  Bailly,  Inc.  pursuant to the  provisions  of a Security

by and between the Assignor and the Agent; and

                  WHEREAS,  the  Assignor  is a party to,  and from time to time
will  become  entitled  to  receive  moneys  under and by  virtue  of, a certain

                  NOW,  THEREFORE,  in  consideration  of the premises and other

the  Contract,  (c) there has been no default on the part of the Assignor or any

hereafter  due and to  become  due to the  Assignor  under or by  reason  of the
Contract,  together  with all  cash and  non-cash  proceeds  thereof;  provided,

perform any of its  obligations  thereunder and any rejection of any performance
rendered by the Assignor under or in connection with the Contract.

deliver such  instruments or checks to the order of the Agent. The Assignor does
hereby  irrevocably  (subject  to  revocation  with the  consent  of the  Agent)
designate and appoint (which appointment is coupled with an interest) the Agent,
and the Agent's  successors in interest by operation of law, the Assignor's true

Assignor's  name,  place,  and  stead,  but at the sole cost and  expense of the
Assignor,  to receive,  endorse,  and collect all Items of Payment,  and to ask,

contrary notwithstanding,  the Debtor shall remain liable to observe and perform
all the  terms and  conditions  to be  observed  and  performed  by it under any
contract,   agreement,   warranty  or  other  obligation  with  respect  to  the
Collateral;  and  shall do  nothing  to impair  the  security  interests  herein
granted.  The Agent shall not have any  obligation  or liability  under any such
contract,  agreement, warranty or obligation by reason of or arising out of this
Security  Agreement  or the receipt by the Agent of any payment  relating to any
Collateral,  nor shall the Agent be  required  to perform or fulfill  any of the
obligations of the Debtor with respect to the Collateral, to make any inquiry as
to the nature or sufficiency of any payment received by it or the sufficiency of
the  performance  of any party's  obligations  with  respect to any  Collateral.
Furthermore,  the  Agent  shall not be  required  to file any claim or demand to
collect any amount due or to enforce the performance of any party's  obligations
with respect to, the Collateral.

Section 2.03.     Sales and Collections.

(a) Sales of  Inventory  in the  Ordinary  Course  of  Business.  The  Debtor is
authorized (i) to sell in the ordinary course of its business for fair value and
on an  arm's-length  basis  any of its  Inventory  normally  held by it for such
purpose and (ii) to use and consume, in the ordinary course of its business, any
raw materials,  supplies and materials normally held by it for such purpose. The
Agent may, upon the occurrence of any Event of Default, without cause or notice,
curtail or terminate such authority at any time.

(b) Collection of Receivables. The Debtor is authorized to collect amounts owing
to it with respect to the Collateral, except as otherwise provided in connection
with the Assignment of Federal Contract, if any as provided herein. However, the
Agent may, upon and during the continuance of an Event of Default or a Potential
Event of Default, notify Account Debtors obligated to make payments under any or
all Receivables or Other  Intangibles that the Agent has a security  interest in
such Collateral and that payments shall be made directly to the Agent.  Upon the
request of the Agent upon and during the continuance of an Event of Default or a
Potential  Event of Default,  as the case may be, the Debtor will so notify such
Account  Debtors  and  will  execute  such  contract  assignments,   notices  of
assignment or other  documents as may be required by such Account  Debtors.  The
Debtor will use all  reasonable  efforts to cause each Account  Debtor to comply
with the foregoing  instruction.  In furtherance  of the  foregoing,  the Debtor
authorizes the Agent upon and during the continuance of an Event of Default or a
Potential  Event of Default (i) to ask for,  demand,  collect,  receive and give
acquittances  and  receipts  for any and all amounts due and to become due under
any Collateral and in the name of the Debtor or its own name or otherwise,  (ii)
to  take  possession  of,  endorse  and  collect  any  checks,   drafts,  notes,
acceptances  or other  instruments  for the  payment  of  monies  due  under any
Collateral  and (iii) to file any claim or take any other action in any court of
law or equity or  otherwise  which it may deem  appropriate  for the  purpose of
collecting  any  amounts  due under any  Collateral.  The  Agent  shall  have no
obligation  to obtain or record any  information  relating to the source of such
funds or the obligations in respect of which payments have been made.

Section 2.04.     Segregation of Proceeds.

(a) Cash Collateral  Account  Maintained by Agent. Upon an Event of Default or a
Potential  Event of  Default,  the Agent shall have the right at any time during
the  continuance  thereof to cause to be opened and  maintained at the office of
the Agent in McLean,  Virginia a  non-interest  bearing  bank account (the "Cash
Collateral  Account") which will contain only Proceeds.  Any "cash proceeds" (as
such term is defined  in  Section  9-306(1)  of the UCC)  received  by the Agent
directly from Account  Debtors  obligated to make payments under  Receivables or
Other Intangibles  pursuant to Section 2.3 hereof or from the Debtor pursuant to
clause (b) of this Section 2.4,  whether  consisting of checks,  notes,  drafts,
bills of exchange, money orders,  commercial paper or other Proceeds received on
account of any  Collateral,  shall be promptly  deposited in the Cash Collateral
Account, and until so deposited shall be held in trust for the Agent as property
of the  Agent  and shall not be  commingled  with any  funds of the  Debtor  not
constituting  Proceeds  of  Collateral.  The name in which  the Cash  Collateral
Account is carried shall clearly  indicate that the funds deposited  therein are
the  property  of the  Debtor,  subject to the  security  interest  of the Agent
hereunder. Such Proceeds, when deposited,  shall continue to be security for the
Obligations   and  shall  not  constitute   payment  thereof  until  applied  as
hereinafter  provided.  The Agent shall have sole  dominion and control over the
funds deposited in the Cash Collateral Account,  and such funds may be withdrawn
therefrom only by the Agent.

(b) Deposit of  Proceeds  by the Debtor.  Upon notice by the Agent to the Debtor
that the Cash  Collateral  Account has been  opened,  the Debtor shall cause all
cash  Proceeds  collected  by it to be  delivered  to the Agent  forthwith  upon
receipt,  in the original  form in which  received  (with such  endorsements  or
assignments as may be necessary to permit collection  thereof by the Agent), and
for such  purpose the Debtor  hereby  irrevocably  authorizes  and  empowers the
Agent,  its officers,  employees and  authorized  agents to endorse and sign the
name of the Debtor on all checks, drafts, money orders or other media of payment
so delivered,  and such endorsements or assignments shall, for all purposes,  be
deemed to have been made by the Debtor prior to any  endorsement  or  assignment
thereof by the Agent.  The Agent may use any  convenient or customary  means for
the purpose of collecting  such checks,  drafts,  money orders or other media of
payment.

Section 2.05.  Verification  of  Receivables.  The Agent shall have the right to
make test  verifications of Receivables in any reasonable manner and through any
medium that it considers  advisable,  and the Debtor  agrees to furnish all such
assistance and  information  as the Agent may  reasonable  require in connection
therewith.  The Debtor at its expense will cause its chief financial  officer to
furnish to the Agent at any reasonable  time and from time to time promptly upon
the Agent's reasonable request,  the following reports:  (i) a reconciliation of
all Receivables, (ii) an aging of all Receivables, (iii) trial balances and (iv)
a test verification of such Receivables as the Agent may request.

Section 2.06.     Release of Collateral.

(a) Security  Interest of Agent Ceases Upon Permitted  Dispositions.  The Debtor
may sell or realize upon or transfer or otherwise  dispose of Collateral only to
the extent permitted by Section 4.13, and the security interests of the Agent in
such  Collateral so sold,  realized upon or disposed of (but not in the Proceeds
arising from such sale, realization or disposition) shall cease immediately upon
such sale, realization or disposition, without any further action on the part of
the Agent.  The Agent,  if requested in writing by the Debtor but at the expense
of the Debtor,  is hereby  authorized  and  instructed to deliver to the Account
Debtor or the purchaser or other transferee of any such Collateral a certificate
stating  that the Agent no longer  has a  security  interest  therein,  and such
Account Debtor or such purchaser or other  transferee  shall be entitled to rely
conclusively on such certificate for any and all purposes.

(b) Filing of  Termination  Statements.  Upon the  payment in full of all of the
Obligations  and if  there  is no  commitment  by any  Lender  to  make  further
advances,  incur obligations or otherwise give value, the Agent will (as soon as
reasonably  practicable  after receipt of notice from the Debtor  requesting the
same but at the  expense  of the  Debtor)  deliver  to the  Debtor  (i) for each
jurisdiction  in  which a UCC  financing  statement  is on file to  perfect  the
security  interests  granted to the Agent  hereunder,  a  termination  statement
(appropriately  completed)  to the  effect  that the  Agent no  longer  claims a
security interest under such financing statement,  and (ii) such other documents
as  the  Debtor  shall  reasonably  request   evidencing   satisfaction  of  the
Obligations  and the  release  of the  security  interests  granted to the Agent
hereunder.

ARTICLE III.

                                      REPRESENTATIONS AND WARRANTIES

         The Debtor represents and warrants that:

Section 3.01. Title to Collateral.  Except for the security interests granted to
the Agent  pursuant to this  Security  Agreement  and as otherwise  permitted by
Section 6.2(a) of the Revolving Credit  Agreement,  the Debtor is the sole owner
of each item of the Collateral,  having good and marketable title thereto,  free
and clear of any and all Liens.

Section 3.02.     Validity, Perfection and Priority of Security Interests.

(a) By complying  with Section 4.1 hereof,  the Debtor will have created a valid
security  interest in favor of the Agent in all existing  Collateral  and in all
identifiable  Proceeds of such  Collateral,  which security  interest (except in
respect of  Collateral  not located at a facility  identified  on  Schedule  3.7
hereto  and motor  vehicles  for  which the  exclusive  manner of  perfecting  a
security interest therein is by noting such security interest in the certificate
of title in accordance with local law) would be prior to the claims of a trustee
in bankruptcy under Section 544(a) of the Bankruptcy Code. Continuing compliance
by the Debtor  with the  provisions  of Section  4.2 hereof will also (i) create
valid security interests in all Collateral acquired after the date hereof and in
all  identifiable  Proceeds  of such  Collateral  and (ii) cause  such  security
interests in all Collateral and in all Proceeds which are (A) identifiable  cash
Proceeds of  Collateral  covered by  financing  statements  required to be filed
hereunder,  (B)  identifiable  Proceeds  in  which a  security  interest  may be
perfected  by such  filing  under  the UCC and  (C)  any  Proceeds  in the  Cash
Collateral Account to be duly perfected under the UCC, in each case prior to the
claims of a trustee in bankruptcy  under the Bankruptcy  Code (except in respect
of Collateral not located at a facility identified on Schedule 3.5 hereto).

(b) The  security  interests  of the  Agent  in the  Collateral  located  at the
facilities identified on Schedule 3.5 hereto rank first in priority.  Other than
financing   statements  or  other  similar  documents  perfecting  the  security
interests  in favor of the  Agent,  no  financing  statements,  deeds of  trust,
mortgages or similar documents covering all or any part of the Collateral are on
file or of record in any  government  office in any  jurisdiction  in which such
filing or recording  would be  effective to perfect a security  interest in such
Collateral,  nor is any of the Collateral in the possession of any Person (other
than the Debtor) asserting any claim thereto or security interest therein.

Section 3.03.  Enforceability of Receivables and Other Intangibles.  To the best
knowledge of the Debtor,  each  Receivable  and Other  Intangible is a valid and
binding obligation of the related Account Debtor in respect thereof, enforceable
in accordance with its terms,  except as such  enforceability  may be limited by
applicable bankruptcy,  insolvency,  reorganization,  moratorium or similar laws
affecting  the  enforcement  of  creditors'  rights  generally  and  by  general
provisions of equity (regardless of whether such enforceability is considered in
a  proceeding  in equity or at law),  and  complies  with any  applicable  legal
requirements.

Section 3.04.  Place of Business.  Schedule 3.4  correctly  sets forth the chief
executive  office and principal  place of business of the Debtor and the offices
of the Debtor where records  concerning  Receivables  and Other  Intangibles are
kept.

Section 3.05.  Location of  Collateral.  Schedule 3.5  correctly  sets forth the
location of all Equipment and Inventory,  other than rolling stock, aircraft and
goods in transit.  Except as otherwise  specified in Schedule 3.5, all Inventory
and Equipment  has been located at the address  specified on Schedule 3.5 at all
times during the  four-month  period prior to the date hereof while owned by the
Debtor.  All Inventory has been and will be produced in compliance with the Fair
Labor Standards Act, 29 U.S.C.  ss.ss.  201-219,  except for such non-compliance
which could not reasonably be expected to have a material  adverse effect on the
Debtor. No Inventory is evidenced by a negotiable  document of title,  warehouse
receipt  or bill of  lading.  No  non-negotiable  document  of title,  warehouse
receipt or bill of lading has been  issued to any person  other than the Debtor,
and the Debtor has retained possession of all of such non-negotiable  documents,
warehouse receipts and bills of lading. No amount payable under or in connection
with  any  of  the  Collateral  is  evidenced  by  promissory   notes  or  other
instruments.

Section 3.06.  Trade Names.  Schedule 3.6 correctly sets forth any and all trade
names,  division  names,  assumed  names or other  names  under which the Debtor
currently  transacts  business or has transacted  business within the four-month
period prior to the date hereof.

          Section 3.07.  Patents and  Trademarks.  Schedule 3.7  correctly  sets
          forth all Patents, Patent licenses,  Trademarks and Trademark licenses
          now owned by the Debtor.

ARTICLE IV.

                                                COVENANTS

                  The Debtor covenants and agrees that until all obligations and
liabilities in respect of the Obligations  shall have performed and paid in full
and  until  no  Standby   Letters  of  Credit  are  outstanding  or  fully  cash
collateralized and the Commitments are terminated:

Section 4.01. Perfection of Security Interests. The Debtor will, at its expense,
cause all filings and recordings and other actions  specified on Schedule 4.1 to
have been completed on or prior to the Effective Date.

Section 4.02.     Further Actions.

(a) At all times after the date hereof, the Debtor will, at its expense,  comply
with the following:

(i) as to all Receivables,  Other Intangibles,  Equipment and Inventory, it will
cause UCC financing statements and continuation statements to be filed and to be
on file in all  applicable  jurisdictions  as required  to perfect the  security
interests  granted to the Agent  hereunder,  to the extent that  applicable  law
permits perfection of a security interest by filing under the UCC;

(ii)  as to all  Proceeds,  it  will  cause  all UCC  financing  statements  and
continuation  statements  filed in accordance with clause (i) above to include a
statement or a checked box  indicating  that Proceeds of all items of Collateral
described herein are covered;

(iii) as to any amount payable under or in connection with any of the Collateral
which  shall  be or  shall  become  evidenced  by any  promissory  note or other
instrument,  the  Debtor  will  promptly  (but in no event  later  than ten (10)
Business Days after receipt of such note or instrument), pledge and deliver such
note or other  instrument to the Agent as part of the Collateral,  duly endorsed
in a manner reasonably satisfactory to the Agent;

(iv) at the request of the Agent,  the Debtor shall deliver all other Collateral
consisting  of  certificated  securities,  endorsed  for  transfer  in a  manner
reasonably  satisfactory  to the Agent (or  execute  a  securities  intermediary
account  control  agreement  to the  extent  possession  by the  Agent  of  such
securities is not feasible); and

(v) as to all Patents,  Patent licenses,  Trademarks or Trademark licenses,  the
Debtor will effect the recordation or renewal of the recordation of the security
interests of the Agent therein so as to maintain  valid and  perfected  security
interests therein under all applicable state and federal laws.

(b) Further  Assurances.  The Debtor will, from time to time and at its expense,
execute, deliver, file or record such UCC financing statements, applications for
certificates  of title  and such  other  statements,  assignments,  instruments,
documents,  agreements  or other  papers and take any other  action  that may be
necessary or desirable,  or that the Agent may reasonably  request,  in order to
create,  preserve,  perfect,  confirm or validate the  security  interest of the
Agent in the Collateral, to enable the Agent to obtain the full benefits of this
Security  Agreement  or to enable it to exercise  and enforce any of its rights,
powers and remedies hereunder,  including, without limitation, its right to take
possession of the Collateral.  (c) Signature. To the fullest extent permitted by
law, the Debtor authorizes the Agent to sign and file financing and continuation
statements  and amendments  thereto with respect to the  Collateral  without its
signature thereon.

Section 4.03. Change of Name, Identity or Structure.  The Debtor will not change
its name, identity or corporate structure in any manner and, except as set forth
on  Schedule  3.6,  will not conduct its  business  under any trade,  assumed or
fictitious  name unless it shall have given the Agent at least  forty-five  (45)
days'  prior  written  notice  thereof  and shall have taken all action (or made
arrangements to take such action  substantially  simultaneously with such change
if it is  impossible  to take such action in advance)  necessary  or  reasonably
requested  by the  Agent  to  amend  any  financing  statement  or  continuation
statement relating to the security interests granted hereby in order to preserve
such  security  interests  and to  effectuate  or maintain the priority  thereof
against all Persons.

Section 4.04.  Place of Business and Collateral.  The Debtor will not change the
location of (i) its places of business, (ii) its chief executive office or (iii)
the  office or other  locations  where it keeps or holds any  Collateral  or any
records relating thereto from the applicable  location listed on Schedule 3.4 or
3.5 unless,  prior to such change, it notifies the Agent forty-five (45) days in
advance of such change,  makes all UCC filings required by Section 4.2 and takes
all other action necessary or that the Agent may reasonably request to preserve,
perfect,  confirm and protect the security  interests granted hereby. The Debtor
will in no event  change the  location of any  Collateral  if such change  would
cause the security  interest granted hereby in such Collateral to lapse or cease
to be  perfected.  The Debtor  will at all times  maintain  its chief  executive
office within one of the forty-eight contiguous states in which Article 9 of the
uniform commercial code is in effect.

Section  4.05.  Fixtures.  The Debtor will not permit any  Equipment to become a
fixture  unless it shall  have  given the  Agent at least ten (10)  days'  prior
written  notice  thereof and shall have taken all such action and  delivered  or
caused to be delivered to the Agent all  instruments  and documents,  including,
without  limitation,  waivers and subordination  agreements by any landlords and
mortgagees, and filed all financing statements necessary or reasonably requested
by the Agent, to preserve and protect the security  interest  granted herein and
to effectuate or maintain the priority  thereof  against all Persons;  provided,
however,  that,  so long as no Event of  Default or  Potential  Event of Default
shall have  occurred  and be  continuing,  the Debtor  shall not be obligated to
comply with the provisions of this Section 4.5 with respect to the first $50,000
of Equipment (determined based on the then fair market value thereof).

Section 4.06.  Maintenance of Records.  The Debtor will keep and maintain at its
own cost and expense complete books and records relating to the Collateral which
are satisfactory to the Agent  including,  without  limitation,  a record of all
payments received and all credits granted with respect to the Collateral and all
of its other  dealings with the  Collateral.  The Debtor will mark its books and
records pertaining to the Collateral to evidence this Security Agreement and the
security interests granted hereby.  For the Agent' further security,  the Debtor
agrees  that the Agent  shall  have a special  property  interest  in all of the
Debtor's  books and records  pertaining to the  Collateral  and the Debtor shall
deliver  and  turn  over any  such  books  and  records  to the  Agent or to its
representatives at any time on demand of the Agent.

Section  4.07.  Compliance  with Laws The  Debtor  will  comply in all  material
respects with all acts, rules,  regulations,  orders,  decrees and directions of
any government or any state or local government  applicable to the Collateral or
any part  thereof or to the  operation of the  Debtor's  business  except to the
extent that the failure to comply  would not have a material  adverse  effect on
the  financial or other  condition of the Debtor;  provided,  however,  that the
Debtor may contest any act, rule, regulation,  order, decree or direction in any
reasonable  manner which shall not, in the sole opinion of the Agent,  adversely
affect the Agent's  rights or, in the case of  Collateral  located at a facility
identified on Schedule 3.7 hereto,  the first priority of its security  interest
in the Collateral.

Section 4.08. Payment of Taxes. The Debtor will pay promptly when due all taxes,
assessments and governmental charges or levies imposed upon the Collateral or in
respect of its income or  profits  therefrom,  as well as all claims of any kind
(including claims for labor, materials and supplies), except that no such charge
need be paid if (i) the  validity  thereof is being  contested  in good faith by
appropriate  proceedings and (ii) such charge is adequately  reserved against in
accordance  with  generally  accepted  accounting  principles,  as  consistently
applied.

Section 4.09.  Compliance with Terms of Accounts and Contracts.  The Debtor will
perform and comply in all material  respects with all of its  obligations  under
all agreements  relating to the Collateral to which it is a party or by which it
is bound.

Section  4.10.  Limitation on Liens on  Collateral.  The Debtor will not create,
permit or suffer to exist,  and will  defend  the  Collateral  and the  Debtor's
rights with respect  thereto  against and take such other action as is necessary
to  remove  any  Lien,  security  interest,  encumbrance,  or claim in or to the
Collateral other than the security interests created hereunder and such Liens to
the  extent  permitted  pursuant  to  Section  6.2(a)  of the  Revolving  Credit
Agreement.

Section 4.11. Limitations on Modifications of Receivables and Other Intangibles;
No Waivers or Extensions.  The Debtor will not (i) amend,  modify,  terminate or
waive any  provisions  of any material  Receivable  or Other  Intangible  in any
manner which might, when taken together with all such other Receivables or Other
Intangibles,  respectively,  materially  reduce the value of all  Receivables or
Other  Intangibles,  respectively,  in the  Collateral,  (ii)  fail to  exercise
promptly and  diligently  each and every  material right which it may have under
each  Receivable  and Other  Intangible  or (iii) fail to deliver to the Agent a
copy of each material demand,  notice or document received by it relating in any
way to any Receivable or Other Intangible.

Section  4.12.   Maintenance  of  Insurance.   The  Debtor  will  maintain  with
financially   sound  insurance   companies   licensed  to  do  business  in  the
jurisdictions  in which the  Collateral  is located  insurance  policies  on the
Inventory and Equipment in accordance  with the  provisions of Section 6.1(m) of
the Revolving Credit Agreement.

Section 4.13.  Limitations on  Dispositions  of Collateral.  The Debtor will not
directly or indirectly (through the sale of stock, merger or otherwise), without
the prior  written  consent of the Agent,  sell,  transfer,  lease or  otherwise
dispose of any of the Collateral,  or attempt, offer or contract to do so except
for (i) sales of Inventory in the ordinary course of its business for fair value
in  arm's-length  transactions  and  (ii) so long as no  Event  of  Default  (or
Potential  Event of Default) has occurred and is continuing,  dispositions  in a
commercially reasonable manner of Equipment which has become redundant, worn out
or obsolete or which should be replaced so as to improve  productivity,  so long
as the  proceeds  of any such  disposition  are (x) used to acquire  replacement
equipment  which has comparable or better utility and equivalent or better value
and which is subject to a first priority security interest in favor of the Agent
therein,  except  as  permitted  by  Section  6.2(a)  of  the  Revolving  Credit
Agreement, or (y) applied to repay the Obligations. The inclusion of Proceeds of
the Collateral under the security interests granted hereby shall not be deemed a
consent by the Agent to any sale or disposition of any Collateral  other than as
permitted by this Section 4.13.

Section 4.14. Further  Identification of Collateral.  The Debtor will furnish to
the Agent from time to time  statements and schedules  further  identifying  and
describing  the  Collateral  and  such  other  reports  in  connection  with the

the Agent if the value of the Collateral located at the facilities identified on
Schedule 3.7 hereto is less than 80% of the value of all of the Collateral.

Section  4.15.  Notices.  The  Debtor  will  advise  the Agent  promptly  and in
reasonable detail (i) of any Lien, security interest,  encumbrance or claim made
or  asserted  against  any of the  Collateral,  other  than,  unless  reasonably
requested  by the Agent,  Liens  permitted  by Section  6.2(a) of the  Revolving
Credit  Agreement,  (ii)  of  any  material  change  in the  composition  of the
Collateral,  and (iii) of the  occurrence  of any other event which would have a
material  adverse  effect on the  aggregate  value of the  Collateral  or on the
security interests granted to the Agent in this Security Agreement.

Section 4.16.  Change of Law. The Debtor shall promptly  notify the Agent of any
change in law known to it which (i) adversely  affects or will adversely  affect
the validity,  perfection or priority of the security  interests granted hereby,
(ii)  requires  or will  require a change in the  proceedings  to be followed in
order to maintain and protect such  validity,  perfection  and priority or (iii)
could result in the Agent not having a perfected security interest in any of the
Collateral.

Section 4.17.     Right of Inspection.

(a) Access to Books and Records. The Debtor shall,  following any request by the
Agent and upon reasonable  notice,  permit the Agent or its  representatives  to
have  full  and free  access  during  normal  business  hours to all the  books,
correspondence and records of the Debtor,  and the Agent or its  representatives
may examine the same, take extracts therefrom, make photocopies thereof and have
such discussions with officers,  employees and public  accountants of the Debtor
as the Agent may deem reasonably  necessary,  and the Debtor agrees to render to
the Agent, at the Debtor's cost and expense,  such clerical and other assistance
as  may  be  reasonably  requested  with  regard  thereto.  The  Agent  and  its
representatives  shall upon  reasonable  notice and during normal business hours
also  have the  right to enter  into  and  upon any  premises  where  any of the
Inventory or the  Equipment is located for the purpose of  inspecting  the same,
observing its use or protecting the interests of the Agent therein.

(b)  Audits.  The  Debtor  shall  permit  the  Lenders,   the  Agent  and  their
representatives  and advisors to review the operations of the Debtor and perform
the audits and  examinations  as  provided  in Section  6.1(l) of the  Revolving
Credit Agreement.

          Section  4.18.  Maintenance  of  Equipment.  The Debtor  will,  at its
          expense, maintain the Equipment in good operating condition,  ordinary
          wear and tear excepted.

Section 4.19.     Covenants Regarding Patent and Trademark Collateral.

(a)  Generally.  At  such  time as the  Debtor  shall  acquire  any  Patents  or
Trademarks,  it will comply with the terms,  covenants  and  warranties  of this
Section 4.19.

(b) Continued Use of Trademark.  The Debtor (either itself or through licensees)
will, unless the Debtor shall reasonably determine,  after consultation with the
Agent,  that a Trademark  is of  negligible  economic  value to the Debtor,  (i)
continue  to use each  Trademark  on each  and  every  Trademark  class of goods
applicable  to its current  products  and  services as  reflected in its current
catalogs,  brochures and price lists in order to maintain each Trademark in full
force and free from any claim of  abandonment  for non-use,  (ii) maintain as in
the past the quality of products  and  services  offered  under each  Trademark,
(iii) employ each Trademark with the appropriate  notice of  registration,  (iv)
not adopt or use any mark which is confusingly  similar to a colorable imitation
of any Trademark and (v) not (and not permit any licensee or sublicensee thereof
to) do any act or knowingly  omit to do any act whereby any Trademark may become
invalidated.

(c) No  Abandonment.  The Debtor will not,  unless the Debtor  shall  reasonably
determine,  after  consultation  with the Agent,  that a Patent is of negligible
economic  value to the  Debtor,  do any act,  or  knowingly  omit to do any act,
whereby any Patent may be abandoned or dedicated.

(d) Notice of Abandonment or Adverse Determinations. The Debtor shall notify the
Agent  immediately if it knows,  or has reason to know,  that any application or
registration  relating  to any  Patent or  Trademark  may  become  abandoned  or
dedicated,  or of any adverse determination or development  (including,  without
limitation,  the institution of, or any such determination or development in any
proceeding  in the United  States  Patent and  Trademark  Office or any court of
tribunal in any  country)  regarding  the  Debtor's  ownership  of any Patent or
Trademark, its right to register the same or keep and maintain the same.

(e) Filings After Notice to Agent.  In no event shall the Debtor,  either itself
or through any agent,  employee,  licensee or designee,  file an application for
registration  of any  Patent or  Trademark  with the  United  States  Patent and
Trademark  Office or any  similar  office or agency in any other  country or any
political  subdivision  thereof,  unless it promptly informs the Agent and, upon
request of the Agent, executes and delivers any and all agreements, instruments,
documents  and papers as the Agent may request to evidence the Agent's  security
interest in such Patent or Trademark and the goodwill and general intangibles of
the  Debtor  relating  thereto or  represented  thereby,  and the Debtor  hereby
constitutes the Agent its attorney-in-fact to execute and file all such writings
for the foregoing purposes, all such acts of such attorney being hereby ratified
and confirmed.

(f) Pursuit of Applications  and Maintenance of  Registrations.  The Debtor will
take all necessary  steps,  including,  without  limitation,  in any  proceeding
before the United States Patent and  Trademark  Office or any similar  office or
agency in any other country or any political  subdivision  thereof,  to maintain
and pursue each  application  (and to obtain the relevant  registration)  and to
maintain each  registration  of the Patents and  Trademarks,  including  without
limitation, filing of applications for renewal, affidavits of use and affidavits
of incontestability;  provided,  however, that no such Patent or Trademark shall
be required to be  maintained  or pursued to the extent such Patent or Trademark
is  determined  by the  Debtor,  after  consultation  with the  Agent,  to be of
negligible economic value to the Debtor.

(g) Notice of  Infringement.  If any of the Patent and  Trademark  Collateral is
infringed,  misappropriated  or  diluted  by a third  party,  the  Debtor  shall
promptly  notify the Agent after it learns thereof and shall,  unless the Debtor
shall reasonably determine,  after consultation with the Agent, that such Patent
and Trademark Collateral is of negligible economic value to the Debtor, promptly
sue for infringement, misappropriation of dilution, seek injunctive relief where
appropriate   and  recover   any  and  all   damages   for  such   infringement,
misappropriation  or  dilution,  or take such other  action as the Debtor  shall
reasonably deem appropriate  under the  circumstances to protect such Patent and
Trademark Collateral.

Section 4.20.  Termination  of Federal  Contracts.  With respect to each Federal
Contract in respect of which the Debtor is required to execute an  Assignment of
Federal  Contract in accordance with Section 4.21 hereof,  the Debtor shall give
prompt written  notice to the Agent if the U.S.  Government  shall  terminate or
threaten to  terminate  (whether  for  convenience  or default) any such Federal
Contract  with the Debtor  having a value  (including  unexercised  options)  of
$100,000 or more. In addition,  the Debtor shall give prompt  written  notice to
the Agent if the U.S.  Government  shall  terminate or threaten to terminate any
contract between the U.S.  Government and any other prime contractor under which
the  Debtor  is a  subcontractor  if the  value of such  subcontract  (including
unexercised options) is $100,000 or more.

Section 4.21. Federal Contracts.  The Debtor shall provide to the Agent, as soon
as reasonably  practicable but not later than forty-five (45) days following the
end of each Fiscal Quarter,  a report identifying each Federal Contract to which
it is a party,  having  attached  thereto  a copy of the first two pages of such
Federal  Contract  and any  amendment  thereto,  to the  extent  not  previously
provided to the Agent.  At the request of the Agent  (unless an Event of Default
shall have  occurred and be  continuing,  in which case no such request shall be
required),  the Debtor shall  execute and deliver to the Agent an  Assignment of
Federal Contract, in substantially the form of Exhibit A hereto (the "Assignment
of Federal Contract"), and execute any other instruments or take any other steps
required  by the Agent in order  that all moneys due or to become due under such
Federal  Contracts shall be assigned to the Agent and notice thereof given under
the Assignment of Claims Act, including without  limitation  delivery of Notices
of Assignments with respect to each Federal Contract as contemplated by Appendix
A to Exhibit A hereto.

Section 4.22.  Reimbursement  Obligation.  Should the Debtor fail to comply with
the provisions of this Security Agreement, the Revolving Credit Agreement or any
other agreement relating to the Collateral such that the value of any Collateral
or the validity,  perfection,  rank or value of any security interest granted to
the  Agent  hereunder  or  thereunder  is  thereby   diminished  or  potentially
diminished or put at risk (as reasonably  determined by the Agent), the Agent on
behalf of the Debtor may, but shall not be required to,  effect such  compliance
on behalf of the Debtor,  and the Debtor shall  reimburse the Agent for the cost
thereof on demand,  and interest shall accrue on such  reimbursement  obligation
from the date the relevant  costs are incurred  until  reimbursement  thereof in
full at the Default Rate.

ARTICLE V.

                                      REMEDIES; RIGHTS UPON DEFAULT

Section 5.01. UCC Rights.  In the event that any portion of the  Obligations has
been declared or becomes due and payable in accordance with the Revolving Credit
Agreement or other Credit  Documents and such  Obligations have not been paid in
full,  the Agent may in addition to all other rights and remedies  granted to it
in this Security  Agreement and in any other  instrument or agreement  securing,
guarantying,  evidencing or relating to the Obligations, exercise (i) all rights
and  remedies of a secured  party under the UCC (whether or not in effect in the
jurisdiction  where  such  rights  are  exercised)  and  (ii) all  other  rights
available to the Agent at law or in equity.

          Section 5.02.  Payments on Collateral.  Without limiting the rights of
          the Agent under any other provision of this Security Agreement,  if an
          Event of Default shall occur and be continuing:

(i) all payments  received by the Debtor under or in connection  with any of the
Collateral  shall  be held by the  Debtor  in  trust  for the  Agent,  shall  be
segregated  from other funds of the Debtor and shall  forthwith  upon receipt by
the Debtor be turned  over to the  Agent,  in the same form as  received  by the
Debtor  (duly  indorsed  by the  Debtor  to the  Agent,  if  required  to permit
collection thereof by the Agent); and

(ii) all such  payments  received  by the  Agent  (whether  from the  Debtor  or
otherwise)  may, in the sole  discretion  of the Agent,  be held by the Agent as
collateral  security for, and/or then or at any time thereafter applied in whole
or in part by the Agent to the payment of, the expenses and the  Obligations  as
set forth in Section 5.11 hereof.

Section 5.03.  Possession of Collateral.  In  furtherance of the foregoing,  the
Debtor  expressly  agrees  that,  if an  Event of  Default  shall  occur  and be
continuing, the Agent may (i) by judicial powers, or without judicial process if
it can be done without breach of the peace, enter any premises where any of such
Collateral is or may be located and,  without  charge or liability to the Agent,
seize and remove such  Collateral from such premises and (ii) have access to and
use of the Debtor's books and records relating to such Collateral.

Section 5.04.     Sale of Collateral; Notice.

(a) Sale of Collateral.  The Debtor expressly agrees that if an Event of Default
shall occur and be continuing, the Agent, without demand of performance or other
demand or notice of any kind (except the notice  specified below of the time and
place of any public or private  sale) to or upon the Debtor or any other  Person
(all of which  demands  and/or  notices are hereby  waived by the  Debtor),  may
forthwith (i) apply the cash, if any, then held by it as collateral as specified
in Section  5.11 hereof and (ii) if there shall be no cash or such cash shall be
insufficient to pay the Obligations in full, collect,  receive,  appropriate and
realize upon the Collateral,  and/or sell, assign,  give an option or options to
purchase or otherwise  dispose of and deliver the  Collateral (or contract to do
so) or any part thereof in one or more parcels (which need not be in round lots)
at public or  private  sale,  at any  office of the Agent or  elsewhere  in such
manner as is  commercially  reasonable and, as the Agent may deem best, for cash
or on credit or for future delivery  without  assumption of any credit risk. The
Agent shall have the right upon any such public sale,  and, if the Collateral is
of a type customarily  sold in a recognized  market or is of a type which is the
subject of widely distributed  standard price quotations,  upon any such private
sale or sales,  to purchase the whole or any part of the Collateral so sold, and
thereafter to hold the same,  absolutely and free from any right or claim of any
kind. To the extent  permitted by applicable  law, the Debtor waives all claims,
damages  and  demands  against  the  Agent  arising  out  of  the   foreclosure,
repossession, retention or sale of the Collateral.

(b) Notice of Sale. Unless the Collateral threatens to decline speedily in value
or is of a type  customarily sold on a recognized  market,  the Agent shall give
the Debtor  ten (10)  days'  written  notice of its  intention  to make any such
public or private sale or sale at a broker's board or on a securities  exchange.
Such  notice  shall (i) in the case of a public  sale,  state the time and place
fixed  for  such  sale,  (ii) in the  case of sale at a  broker's  board or on a
securities  exchange,  state the board or  exchange  at which such sale is to be
made and the day on which the  Collateral,  or the portion  thereof  being sold,
will first be offered  for sale and (iii) in the case of a private  sale,  state
the day after which such sale may be consummated.  The Agent shall not obligated
to make any such sale  pursuant  to any such  notice.  The Agent may adjourn any
public or private  sale or cause the same to be  adjourned  from time to time by
announcement at the time and place fixed for the sale, and such sale may be made
at any time or place to which the same may be so  adjourned.  In the case of any
sale of all or any part of the Collateral on credit or for future delivery,  the
Collateral  so sold may be retained by the Agent until the selling price is paid
by the purchaser thereof, but the Agent shall not incur any liability in case of
the failure of such purchase to take up and pay for the  Collateral so sold and,
in the case of such failure, such Collateral may again be sold upon like notice.

(c) Special  Provisions  Relating to Sales of Securities.  The Debtor recognizes
that  the  Agent  may be  unable  to  effect  a  public  sale  of any or all the
Collateral  constituting a "security" (as such term is defined in the Securities
Act) by reason of  certain  prohibitions  contained  in the  Securities  Act and
applicable state securities laws or otherwise, and may be compelled to resort to
one or more private sales thereof to a restricted  group of purchasers that will
be obliged to agree,  among other things,  to acquire such  securities for their
own account for  investment  and not with a view to the  distribution  or resale
thereof.  The Debtor  acknowledges  and agrees  that any such  private  sale may
result in prices and other terms less  favorable than if such sale were a public
sale and, notwithstanding such circumstances,  agrees that any such private sale
shall be deemed to have been made in a commercially reasonable manner. The Agent
shall be under no obligation to delay a sale of any of Collateral constituting a
security  for the  period of time  necessary  to permit  the  issuer  thereof to
register  such  securities  for public sale under the  Securities  Act, or under
applicable state securities laws, even if such issuer would agree to do so.

Section 5.05.  Rights of Purchasers.  Upon any sale of the  Collateral  (whether
public or  private),  the Agent  shall  have the right to  deliver,  assign  and
transfer  to the  purchaser  thereof  the  Collateral  so sold.  Each  purchaser
(including  the  Agent)  at any such  sale  shall  hold the  Collateral  so sold
absolutely,  free from any claim or right of whatever kind, including any equity
or right of redemption of the Debtor who, to the extent permitted by law, hereby
specifically waives all rights of redemption, including, without limitation, any
right to redeem the Collateral  under Section 9-506 of the UCC, and any right to
a judicial or other stay or approval  which it has or may have under any law now
existing or hereafter adopted.

Section 5.06.     Additional Rights of the Agent.

(a) Right to Maintain Proceedings.  The Agent (i) shall have the right and power
to institute and maintain such suits and proceedings as it may deem  appropriate
to protect and enforce the rights  vested in it by this  Security  Agreement and
(ii) may proceed by suit or suits at law or in equity to enforce such rights and
to foreclose  upon the  Collateral and to sell all or, from time to time, any of
the   Collateral   under  the  judgment  or  decree  of  a  court  of  competent
jurisdiction.

(b)  Appointment  of  Receiver.  The Agent  shall,  to the extent  permitted  by
applicable law,  without notice to the Debtor to any party claiming  through the
Debtor,  without regard to the solvency or insolvency at such time of any Person
then liable for the  payment of any of the  Obligations,  without  regard to the
then value of the Collateral and without requiring any bond from any complainant
in such  proceedings,  be entitled as a matter of right to the  appointment of a
receiver  or  receivers  (who may be the  Agent) of the  Collateral  or any part
thereof,  pending  such  proceedings,  with such powers as the court making such
appointment  shall  confer,  and to the  entry  of an order  directing  that the
profits, revenues and other income of the property constituting the whole or any
part of the Collateral be segregated,  sequestered and impounded for the benefit
of the Agent,  and the Debtor  irrevocably  consents to the  appointment of such
receiver or receivers and to the entry of such order.

(c) No Duty to  Exercise  Rights.  In no event  shall the Agent have any duty to
exercise any rights or take any steps to preserve the rights of the Agent in the
Collateral,  nor shall the Agent be liable to the Debtor or any other Person for
any loss caused by the Agent's failure to meet any obligation imposed by Section
9-207 of the UCC or any successor provision. Without limiting the foregoing, the
Agent  shall be deemed to have  exercised  reasonable  care in the  custody  and
preservation  of the  Collateral in its possession if the Collateral is accorded
treatment  substantially equal to that which the Agent accords its own property,
it being understood that the Agent shall not have any duty or responsibility for
(i) ascertaining or taking action with respect to calls, conversions, exchanges,
maturities,  tenders or other matters relative to any Collateral, whether or not
the Agent has or is deemed to have knowledge of such matters, or (ii) taking any
necessary  steps to preserve  rights  against any  parties  with  respect to any
Collateral.

Section 5.07.     Remedies Not Exclusive, etc.

(a) Remedies Not Exclusive. No remedy conferred upon or reserved to the Agent in
this  Security  Agreement  is intended to be  exclusive  of any other  remedy or
remedies,  but every such remedy shall be cumulative and shall be in addition to
every other  remedy  conferred  herein or now or  hereafter  existing at law, in
equity or by statute.

(b)  Restoration  of Rights.  If the Agent shall have  proceeded  to enforce any
right,  remedy or power under this Security Agreement and the proceeding for the
enforcement  thereof shall have been discontinued or abandoned for any reason or
shall have been  determined  adversely  to the  Agent,  the Debtor and the Agent
shall,   subject  to  any  determination  in  such  proceeding,   severally  and
respectively  be  restored  to their  former  positions  and  rights  under this
Security Agreement,  and thereafter all rights, remedies and powers of the Agent
shall continue as though no such proceedings had been taken.

(c)  Enforcement.  All rights of action  under this  Security  Agreement  may be
enforced by the Agent without the  possession of any  instrument  evidencing any
Obligation or the production  thereof at any trial or other proceeding  relative
thereto, and any suit or proceeding  instituted by the Agent shall be brought in
its name and any judgment shall be held as part of the Collateral.

Section 5.08.     Waiver and Estoppel.

(a) No Actions to Impede Sale of Collateral. The Debtor agrees, to the extent it
may lawfully do so, that it will not at any time in any manner  whatsoever claim
or take the benefit or advantage of any appraisal,  valuation,  stay, extension,
moratorium,  turnover or redemption  law, or any law permitting it to direct the
order in which the  Collateral  shall be sold,  now or at any time  hereafter in
force  which  may  delay,   prevent  or  otherwise  affect  the  performance  or
enforcement  of this  Security  Agreement,  and  hereby  waives  all  benefit or
advantage of all such laws. The Debtor covenants that it will not hinder,  delay
or impede  the  execution  of any power  granted  to the Agent in this  Security
Agreement, any Assignment of Federal Contract or any other Credit Document.

(b) Collateral Sold As An Entirety. The Debtor, to the extent it may lawfully do
so, on behalf of itself and all who claim through or under it, including without
limitation any and all  subsequent  creditors,  vendees,  assignees and lienors,
waives  and  releases  all  rights to demand or to have any  marshalling  of the
Collateral upon any sale, whether made under any power of sale granted herein or
pursuant to judicial  proceedings or under any foreclosure or any enforcement of
this Security Agreement,  and consents and agrees that all of the Collateral may
at any such sale be offered and sold as an entirety.

(c) Waiver of  Notices.  The Debtor  waives,  to the  extent  permitted  by law,
presentment,  demand,  protest  and any notice of any kind  (except  the notices
expressly required hereunder) in connection with this Security Agreement and any
action taken by the Agent with respect to the Collateral.

Section 5.09.     Power of Attorney; Powers Coupled With An Interest.

(a) Power of Attorney.  Without limiting any other right granted hereunder,  the
Debtor hereby irrevocably constitutes and appoints the Agent, with full power of
substitution,  as its true and  lawful  attorney-in-fact  with full  irrevocable
power and  authority in the place and stead of the Debtor and in the name of the
Debtor  or in its  own  name,  from  time  to  time  in the  Agent's  reasonable
discretion,  for the  purpose  of  carrying  out  the  terms  of  this  Security
Agreement,  to take any and all  appropriate  action and to execute  any and all
documents and instruments  which may be necessary or desirable to accomplish the
purpose of this Security  Agreement and,  without limiting the generality of the
foregoing,  hereby gives the Agent the power and right, on behalf of the Debtor,
without notice to or assent by the Debtor, to do the following:

          (i) to pay or  discharge  taxes,  liens,  security  interests or other
          encumbrances levied or placed on or threatened against the Collateral;

(ii) to effect  any  repairs  or any  insurance  called for by the terms of this
Security  Agreement or any other Credit Document,  and to pay all or any part of
the premiums therefor and the costs thereof;

(iii) upon the occurrence and  continuance of any Event of Default and otherwise
to the  extent  provided  in this  Security  Agreement,  (A) to direct any party
liable for any payment  under any of the  Collateral  to make payment of any and
all moneys due and to come due thereunder  directly to the Agent or as the Agent
shall direct,  (B) to receive  payment of and receipt for, and to demand and sue
for, any and all moneys,  claims and other  amounts due and to become due at any
time in respect of or arising out of the Collateral, (C) to sign and indorse and
receive,  take, assign and deliver, any checks,  notes,  drafts,  negotiable and
non-negotiable  instruments,  any invoices,  freight or express bills,  bills of
lading,  storage or warehouse  receipts,  drafts against  debtors,  assignments,
verifications  and  notices in  connection  with  accounts  and other  documents
relating to the  Collateral,  (D) to  commence,  settle,  compromise,  compound,
prosecute,  defend or adjust any claim,  suit, action or proceeding with respect
to, or in connection  with, the  Collateral,  (E) to sell,  transfer,  assign or
otherwise  deal in or with the  Collateral  or any part  thereof,  as fully  and
effectively  as if the Agent were the absolute  owner  thereof and (F) to do, at
its option,  but at the expense of the Debtor, at any time or from time to time,
all acts and things  which the Agent deems  necessary  to  protect,  preserve or
realize upon the Collateral and the Agent's security interest therein,  in order
to effect the intent of this Security Agreement, all as fully and effectively as
the Debtor might do.

(b) Powers Coupled With an Interest.  All authorizations and agencies granted or
provided  herein with respect to the  Collateral,  including the powers  granted
under clause (a) of this Section 5.9, are irrevocable and powers coupled with an
interest.

Section 5.10. Certain Provisions Relating to Securities.  Solely with respect to
any Collateral  constituting a "security" (as defined in the Securities Act), if
an Event of Default shall have occurred and be continuing,  all such  securities
(as defined in the Securities Act)  constituting a part of the Collateral shall,
at the  request  of the  Agent,  be  registered  in the name of the Agent or its
nominee,  and the Agent or its nominee may  thereafter  exercise (i) all voting,
corporate and other rights,  powers and privileges pertaining to such Collateral
at any meeting of shareholders of the issuer thereof or otherwise,  and (ii) any
and all  rights of  conversion,  exchange,  subscription  and any other  rights,
privileges or options  pertaining to such  Collateral as if it were the absolute
owner  thereof  (including,  without  limitation,  the right to  exchange at its
discretion  any  and  all  such  Collateral  upon  the  merger,   consolidation,
reorganization, recapitalization or other fundamental change in the structure of
any such  issuer,  or upon the exercise by the Debtor or the Agent of any right,
privilege or option pertaining to such Collateral,  and in connection therewith,
the right to deposit and deliver any and all such Collateral with any committee,
depositary, transfer agent, registrar or other designated agency upon such terms
and conditions as it may determine), all without liability except to account for
property  actually  received  by it and except as  provided  in  Section  5.6(c)
hereof,  but the Agent  shall  have no duty to the Debtor to  exercise  any such
right, privilege or option and shall not be responsible for any failure to do so
or delay in so doing.

          Section 5.11.  Application of Monies.  The proceeds of any sale of, or
          other  realization  upon, all or any part of the  Collateral  shall be
          applied by the Agent in the following order of priority:

                  first,  to  payment  of the  expenses  of such  sale or  other
realization,  including reasonable  compensation to the Agent and its agents and
counsel,  and all  expenses,  liabilities  and advances  incurred or made by the
Agent, its agents and counsel in connection  therewith or in connection with the
care, safekeeping or otherwise of any or all of the Collateral;

          second, to payment of the Obligations,  in such order as the Agent may
          elect; and

                  third, any surplus then remaining shall be paid to the Debtor,
or its  successors  or assigns,  or to  whomsoever  may be lawfully  entitled to
receive the same (including  pursuant to Section 9-504(1)(C) of the UCC) or as a
court of competent jurisdiction may direct.

ARTICLE VI.

                                              MISCELLANEOUS

Section 6.01. Notices. All notices, requests and other communications to a party
hereunder  shall be in writing  and shall be given to such party at its  address
set forth on the  signature  page hereof or such other address as such party may
hereafter  specify for that  purpose by notice to the other.  Each such  notice,
request or other  communication shall be effective (i) in the case of telephonic
notice (to the extent  expressly  permitted  hereunder),  when made, (ii) in the
case of notice delivered by overnight  express  courier,  one Business Day after
the Business Day such notice was delivered to such courier, (iii) in the case of
notice  delivered by first class mail, three Business Days after being deposited
in the mail,  postage  prepaid,  return receipt  requested,  (iv) in the case of
notice by hand,  when  delivered,  or (v) in the case of notice by any customary
means of telecommunication, when sent provided confirmation of receipt or answer
back has been  received,  in each  case if  addressed  to any  party  hereto  as
provided  herein.  Rejection or refusal to accept,  or the  inability to deliver
because of a changed address of which no notice was given,  shall not affect the
validity of notice given in accordance with this section.

Section 6.02.  No Waiver;  Cumulative  Remedies.  The Agent shall not by any act
(except by a written  instrument  pursuant  to Section  6.3 hereof) be deemed to
have waived any right or remedy hereunder. No failure to exercise, nor any delay
in exercising,  on the part of the Agent any right, power or privilege hereunder
shall operate as a waiver thereof.  No single or partial  exercise of any right,
power or  privilege  hereunder  shall  preclude  any other or  further  exercise
thereof or the exercise of any other right, power or privilege.  A waiver by the
Agent  of any  right  or  remedy  hereunder  on any one  occasion  shall  not be
construed as a bar to any right or remedy which the Agent would  otherwise  have
on any future occasion.  The rights and remedies herein provided are cumulative,
may be  exercised  singly or  concurrently  and are not  exclusive  of any other
rights or remedies provided by law.

Section 6.03.  Amendments  and Waivers.  None of the terms or provisions of this
Security Agreement may be amended,  supplemented or otherwise modified except by
a written  instrument  executed by the Debtor and the Agent;  provided  that any
provision of this  Security  Agreement may be waived by the Agent in a letter or
agreement  executed by the Agent or by telex or facsimile  transmission from the
Agent.

Section 6.04.  Successors and Assigns. The provisions of this Security Agreement
shall be binding  upon and inure to the benefit of the parties  hereto and their
respective  successors and assigns;  provided,  however, that the Debtor may not
assign or transfer any of its rights or obligations  hereunder without the prior
written consent of the Agent.

          Section 6.05. Governing Law. THIS SECURITY AGREEMENT SHALL BE GOVERNED
          BY AND CONSTRUED IN ACCORDANCE  WITH THE LAWS OF THE  COMMONWEALTH  OF
          VIRGINIA,  OTHER  THAN ITS LAWS  RESPECTING  CHOICE OF LAW OTHER  THAN
          THOSE CONTAINED IN THE UCC.

Section 6.06.     Limitation by Law; Severability.

(a) All rights,  remedies and powers provided in this Security  Agreement may be
exercised  only to the extent  that the  exercise  thereof  does not violate any
applicable  provision of law, and all the provisions of this Security  Agreement
are intended to be subject to all applicable  mandatory  provisions of law which
may be controlling  and to be limited to the extent  necessary so that they will
not render this Security Agreement  invalid,  unenforceable in whole or in part,
or not entitled to be recorded,  registered or filed upon the  provisions of any
applicable law.

(b) If any provision hereof is invalid and  unenforceable  in any  jurisdiction,
then, to the fullest extent  permitted by law, (i) the other  provisions  hereof
shall  remain  in full  force  and  effect  in such  jurisdiction  and  shall be
liberally  construed in favor of the Agent in order to carry out the  intentions
of the parties  hereto as nearly as may be possible and (ii) the  invalidity  or
unenforceability  of any provision hereof in any  jurisdiction  shall not affect
the validity or enforceability of such provision in any other jurisdiction.

Section  6.07.  Counterparts.  This  Security  Agreement  may be executed in any
number of counterparts and by different parties hereto on separate counterparts,
each complete set of which, when so executed and delivered by all parties, shall
be an original,  but all such counterparts shall together constitute but one and
the same instrument.

Section 6.08. Expenses of the Agent. The Debtor shall pay to the Agent from time
to time upon demand,  all of the costs and expenses incurred by the Agent or any
Lender (including,  without limitation, the reasonable fees and disbursements of
counsel  and any  amounts  payable  by the  Agent or any  Lender to any of their
respective   agents)  (i)  arising  in  connection   with  the   administration,
modification, amendment, waiver or termination of this Security Agreement or any
document or agreement  contemplated hereby or any consent or waiver hereunder or
thereunder  or (ii)  incurred  in  connection  with the  administration  of this
Security  Agreement,  or any document or agreement  contemplated  hereby,  or in
connection  with the  administration,  sale or other  disposition  of Collateral
hereunder  or  under  any  document  or  agreement  contemplated  hereby  or the
preservation,  protection or defense of the rights of the Agent or any Lender in
and to the Collateral.

Section  6.09.  Indemnification.   The  Debtor  shall  at  all  times  hereafter
indemnify, hold harmless and, on demand, reimburse the Agent and the Lenders and

judicial proceeding by the Debtor against the Agent relating to or involving any
Credit  Agreement  Related Claim hereby shall be brought only in a court located
in the Commonwealth of Virginia,  County of Fairfax, or the Federal court in the

payment of all Obligations,  howsoever  created,  arising or evidenced,  whether

for the ratable benefit of the Lenders, and grants to the Agent, for the ratable
benefit of the Lenders, a first priority and continuing security interest in and
lien on, all of the  Debtor's  right,  title and  interest  in, to and under the

any Person and held by Debtor,  and all  partnership  interests,  whether in the
nature of a joint venture,  limited liability company member's interest,  master
limited partnership, teaming arrangement or otherwise;

(vi) to the extent not included in the foregoing,  all other personal  property,
whether  tangible or intangible,  and wherever located whether within or outside

deposit  account now or hereafter  existing of the Debtor with any bank or other
financial  institution and all monies of the Debtor and all rights to payment of
money of the Debtor;

Security Agreement its interests in any Federal Contract to which it is a party,
or in accounts or receivables due to Debtor under such Federal Contract,  to the
extent,  but only to the extent,  such assignment,  pledge or other  encumbrance
would  breach or violate or would cause Debtor to breach or violate such Federal
Contract or statutes or regulations applicable thereto, it being understood that
this proviso does not apply to, or in any way limit, Debtor's assignment, pledge
or encumbrance of Proceeds of all Federal Contracts to which it is a party.

contrary notwithstanding,  the Debtor shall remain liable to observe and perform
all the  terms and  conditions  to be  observed  and  performed  by it under any
contract,   agreement,   warranty  or  other  obligation  with  respect  to  the

granted.  The Agent shall not have any  obligation  or liability  under any such
contract,  agreement, warranty or obligation by reason of or arising out of this
Security  Agreement  or the receipt by the Agent of any payment  relating to any
Collateral,  nor shall the Agent be  required  to perform or fulfill  any of the
obligations of the Debtor with respect to the Collateral, to make any inquiry as
to the nature or sufficiency of any payment received by it or the sufficiency of
the  performance  of any party's  obligations  with  respect to any  Collateral.
Furthermore,  the  Agent  shall not be  required  to file any claim or demand to
collect any amount due or to enforce the performance of any party's  obligations
with respect to, the Collateral.

Section 2.03.     Sales and Collections.

(a) Sales of  Inventory  in the  Ordinary  Course  of  Business.  The  Debtor is
authorized (i) to sell in the ordinary course of its business for fair value and
on an  arm's-length  basis  any of its  Inventory  normally  held by it for such
purpose and (ii) to use and consume, in the ordinary course of its business, any
raw materials,  supplies and materials normally held by it for such purpose. The
Agent may, upon the occurrence of any Event of Default, without cause or notice,
curtail or terminate such authority at any time.

(b) Collection of Receivables. The Debtor is authorized to collect amounts owing
to it with respect to the Collateral, except as otherwise provided in connection
with the Assignment of Federal Contract, if any as provided herein. However, the
Agent may, upon and during the continuance of an Event of Default or a Potential
Event of Default, notify Account Debtors obligated to make payments under any or
all Receivables or Other  Intangibles that the Agent has a security  interest in
such Collateral and that payments shall be made directly to the Agent.  Upon the
request of the Agent upon and during the continuance of an Event of Default or a
Potential  Event of Default,  as the case may be, the Debtor will so notify such
Account  Debtors  and  will  execute  such  contract  assignments,   notices  of
assignment or other  documents as may be required by such Account  Debtors.  The
Debtor will use all  reasonable  efforts to cause each Account  Debtor to comply
with the foregoing  instruction.  In furtherance  of the  foregoing,  the Debtor
authorizes the Agent upon and during the continuance of an Event of Default or a
Potential  Event of Default (i) to ask for,  demand,  collect,  receive and give
acquittances  and  receipts  for any and all amounts due and to become due under
any Collateral and in the name of the Debtor or its own name or otherwise,  (ii)
to  take  possession  of,  endorse  and  collect  any  checks,   drafts,  notes,
acceptances  or other  instruments  for the  payment  of  monies  due  under any
Collateral  and (iii) to file any claim or take any other action in any court of
law or equity or  otherwise  which it may deem  appropriate  for the  purpose of
collecting  any  amounts  due under any  Collateral.  The  Agent  shall  have no
obligation  to obtain or record any  information  relating to the source of such
funds or the obligations in respect of which payments have been made.

Section 2.04.     Segregation of Proceeds.

(a) Cash Collateral  Account  Maintained by Agent. Upon an Event of Default or a
Potential  Event of  Default,  the Agent shall have the right at any time during
the  continuance  thereof to cause to be opened and  maintained at the office of
the Agent in McLean,  Virginia a  non-interest  bearing  bank account (the "Cash
Collateral  Account") which will contain only Proceeds.  Any "cash proceeds" (as
such term is defined  in  Section  9-306(1)  of the UCC)  received  by the Agent
directly from Account  Debtors  obligated to make payments under  Receivables or
Other Intangibles  pursuant to Section 2.3 hereof or from the Debtor pursuant to
clause (b) of this Section 2.4,  whether  consisting of checks,  notes,  drafts,
bills of exchange, money orders,  commercial paper or other Proceeds received on
account of any  Collateral,  shall be promptly  deposited in the Cash Collateral
Account, and until so deposited shall be held in trust for the Agent as property
of the  Agent  and shall not be  commingled  with any  funds of the  Debtor  not
constituting  Proceeds  of  Collateral.  The name in which  the Cash  Collateral
Account is carried shall clearly  indicate that the funds deposited  therein are
the  property  of the  Debtor,  subject to the  security  interest  of the Agent
hereunder. Such Proceeds, when deposited,  shall continue to be security for the
Obligations   and  shall  not  constitute   payment  thereof  until  applied  as
hereinafter  provided.  The Agent shall have sole  dominion and control over the
funds deposited in the Cash Collateral Account,  and such funds may be withdrawn
therefrom only by the Agent.

(b) Deposit of  Proceeds  by the Debtor.  Upon notice by the Agent to the Debtor
that the Cash  Collateral  Account has been  opened,  the Debtor shall cause all
cash  Proceeds  collected  by it to be  delivered  to the Agent  forthwith  upon
receipt,  in the original  form in which  received  (with such  endorsements  or
assignments as may be necessary to permit collection  thereof by the Agent), and
for such  purpose the Debtor  hereby  irrevocably  authorizes  and  empowers the
Agent,  its officers,  employees and  authorized  agents to endorse and sign the
name of the Debtor on all checks, drafts, money orders or other media of payment
so delivered,  and such endorsements or assignments shall, for all purposes,  be
deemed to have been made by the Debtor prior to any  endorsement  or  assignment
thereof by the Agent.  The Agent may use any  convenient or customary  means for
the purpose of collecting  such checks,  drafts,  money orders or other media of
payment.

Section 2.05.  Verification  of  Receivables.  The Agent shall have the right to
make test  verifications of Receivables in any reasonable manner and through any
medium that it considers  advisable,  and the Debtor  agrees to furnish all such
assistance and  information  as the Agent may  reasonable  require in connection
therewith.  The Debtor at its expense will cause its chief financial  officer to
furnish to the Agent at any reasonable  time and from time to time promptly upon
the Agent's reasonable request,  the following reports:  (i) a reconciliation of
all Receivables, (ii) an aging of all Receivables, (iii) trial balances and (iv)
a test verification of such Receivables as the Agent may request.

Section 2.06.     Release of Collateral.

(a) Security  Interest of Agent Ceases Upon Permitted  Dispositions.  The Debtor
may sell or realize upon or transfer or otherwise  dispose of Collateral only to
the extent permitted by Section 4.13, and the security interests of the Agent in
such  Collateral so sold,  realized upon or disposed of (but not in the Proceeds
arising from such sale, realization or disposition) shall cease immediately upon
such sale, realization or disposition, without any further action on the part of
the Agent.  The Agent,  if requested in writing by the Debtor but at the expense
of the Debtor,  is hereby  authorized  and  instructed to deliver to the Account
Debtor or the purchaser or other transferee of any such Collateral a certificate
stating  that the Agent no longer  has a  security  interest  therein,  and such
Account Debtor or such purchaser or other  transferee  shall be entitled to rely
conclusively on such certificate for any and all purposes.

(b) Filing of  Termination  Statements.  Upon the  payment in full of all of the
Obligations  and if  there  is no  commitment  by any  Lender  to  make  further
advances,  incur obligations or otherwise give value, the Agent will (as soon as
reasonably  practicable  after receipt of notice from the Debtor  requesting the
same but at the  expense  of the  Debtor)  deliver  to the  Debtor  (i) for each
jurisdiction  in  which a UCC  financing  statement  is on file to  perfect  the
security  interests  granted to the Agent  hereunder,  a  termination  statement
(appropriately  completed)  to the  effect  that the  Agent no  longer  claims a
security interest under such financing statement,  and (ii) such other documents
as  the  Debtor  shall  reasonably  request   evidencing   satisfaction  of  the
Obligations  and the  release  of the  security  interests  granted to the Agent
hereunder.

ARTICLE III.

                                      REPRESENTATIONS AND WARRANTIES

         The Debtor represents and warrants that:

Section 3.01. Title to Collateral.  Except for the security interests granted to
the Agent  pursuant to this  Security  Agreement  and as otherwise  permitted by
Section 6.2(a) of the Revolving Credit  Agreement,  the Debtor is the sole owner
of each item of the Collateral,  having good and marketable title thereto,  free
and clear of any and all Liens.

Section 3.02.     Validity, Perfection and Priority of Security Interests.

(a) By complying  with Section 4.1 hereof,  the Debtor will have created a valid
security  interest in favor of the Agent in all existing  Collateral  and in all
identifiable  Proceeds of such  Collateral,  which security  interest (except in
respect of  Collateral  not located at a facility  identified  on  Schedule  3.7
hereto  and motor  vehicles  for  which the  exclusive  manner of  perfecting  a
security interest therein is by noting such security interest in the certificate
of title in accordance with local law) would be prior to the claims of a trustee
in bankruptcy under Section 544(a) of the Bankruptcy Code. Continuing compliance
by the Debtor  with the  provisions  of Section  4.2 hereof will also (i) create
valid security interests in all Collateral acquired after the date hereof and in
all  identifiable  Proceeds  of such  Collateral  and (ii) cause  such  security
interests in all Collateral and in all Proceeds which are (A) identifiable  cash
Proceeds of  Collateral  covered by  financing  statements  required to be filed
hereunder,  (B)  identifiable  Proceeds  in  which a  security  interest  may be
perfected  by such  filing  under  the UCC and  (C)  any  Proceeds  in the  Cash
Collateral Account to be duly perfected under the UCC, in each case prior to the
claims of a trustee in bankruptcy  under the Bankruptcy  Code (except in respect
of Collateral not located at a facility identified on Schedule 3.5 hereto).

(b) The  security  interests  of the  Agent  in the  Collateral  located  at the
facilities identified on Schedule 3.5 hereto rank first in priority.  Other than
financing   statements  or  other  similar  documents  perfecting  the  security
interests  in favor of the  Agent,  no  financing  statements,  deeds of  trust,
mortgages or similar documents covering all or any part of the Collateral are on
file or of record in any  government  office in any  jurisdiction  in which such
filing or recording  would be  effective to perfect a security  interest in such
Collateral,  nor is any of the Collateral in the possession of any Person (other
than the Debtor) asserting any claim thereto or security interest therein.

Section 3.03.  Enforceability of Receivables and Other Intangibles.  To the best
knowledge of the Debtor,  each  Receivable  and Other  Intangible is a valid and
binding obligation of the related Account Debtor in respect thereof, enforceable
in accordance with its terms,  except as such  enforceability  may be limited by
applicable bankruptcy,  insolvency,  reorganization,  moratorium or similar laws
affecting  the  enforcement  of  creditors'  rights  generally  and  by  general
provisions of equity (regardless of whether such enforceability is considered in
a  proceeding  in equity or at law),  and  complies  with any  applicable  legal
requirements.

Section 3.04.  Place of Business.  Schedule 3.4  correctly  sets forth the chief
executive  office and principal  place of business of the Debtor and the offices
of the Debtor where records  concerning  Receivables  and Other  Intangibles are
kept.

Section 3.05.  Location of  Collateral.  Schedule 3.5  correctly  sets forth the
location of all Equipment and Inventory,  other than rolling stock, aircraft and
goods in transit.  Except as otherwise  specified in Schedule 3.5, all Inventory
and Equipment  has been located at the address  specified on Schedule 3.5 at all
times during the  four-month  period prior to the date hereof while owned by the
Debtor.  All Inventory has been and will be produced in compliance with the Fair
Labor Standards Act, 29 U.S.C.  ss.ss.  201-219,  except for such non-compliance
which could not reasonably be expected to have a material  adverse effect on the
Debtor. No Inventory is evidenced by a negotiable  document of title,  warehouse
receipt  or bill of  lading.  No  non-negotiable  document  of title,  warehouse
receipt or bill of lading has been  issued to any person  other than the Debtor,
and the Debtor has retained possession of all of such non-negotiable  documents,
warehouse receipts and bills of lading. No amount payable under or in connection
with  any  of  the  Collateral  is  evidenced  by  promissory   notes  or  other
instruments.

Section 3.06.  Trade Names.  Schedule 3.6 correctly sets forth any and all trade
names,  division  names,  assumed  names or other  names  under which the Debtor
currently  transacts  business or has transacted  business within the four-month
period prior to the date hereof.

          Section 3.07.  Patents and  Trademarks.  Schedule 3.7  correctly  sets
          forth all Patents, Patent licenses,  Trademarks and Trademark licenses
          now owned by the Debtor.

ARTICLE IV.

                                                COVENANTS

                  The Debtor covenants and agrees that until all obligations and
liabilities in respect of the Obligations  shall have performed and paid in full
and  until  no  Standby   Letters  of  Credit  are  outstanding  or  fully  cash
collateralized and the Commitments are terminated:

Section 4.01. Perfection of Security Interests. The Debtor will, at its expense,
cause all filings and recordings and other actions  specified on Schedule 4.1 to
have been completed on or prior to the Effective Date.

Section 4.02.     Further Actions.

(a) At all times after the date hereof, the Debtor will, at its expense,  comply
with the following:

(i) as to all Receivables,  Other Intangibles,  Equipment and Inventory, it will
cause UCC financing statements and continuation statements to be filed and to be
on file in all  applicable  jurisdictions  as required  to perfect the  security
interests  granted to the Agent  hereunder,  to the extent that  applicable  law
permits perfection of a security interest by filing under the UCC;

(ii)  as to all  Proceeds,  it  will  cause  all UCC  financing  statements  and
continuation  statements  filed in accordance with clause (i) above to include a
statement or a checked box  indicating  that Proceeds of all items of Collateral
described herein are covered;

(iii) as to any amount payable under or in connection with any of the Collateral
which  shall  be or  shall  become  evidenced  by any  promissory  note or other
instrument,  the  Debtor  will  promptly  (but in no event  later  than ten (10)
Business Days after receipt of such note or instrument), pledge and deliver such
note or other  instrument to the Agent as part of the Collateral,  duly endorsed
in a manner reasonably satisfactory to the Agent;

(iv) at the request of the Agent,  the Debtor shall deliver all other Collateral
consisting  of  certificated  securities,  endorsed  for  transfer  in a  manner
reasonably  satisfactory  to the Agent (or  execute  a  securities  intermediary
account  control  agreement  to the  extent  possession  by the  Agent  of  such
securities is not feasible); and

(v) as to all Patents,  Patent licenses,  Trademarks or Trademark licenses,  the
Debtor will effect the recordation or renewal of the recordation of the security
interests of the Agent therein so as to maintain  valid and  perfected  security
interests therein under all applicable state and federal laws.

(b) Further  Assurances.  The Debtor will, from time to time and at its expense,
execute, deliver, file or record such UCC financing statements, applications for
certificates  of title  and such  other  statements,  assignments,  instruments,
documents,  agreements  or other  papers and take any other  action  that may be
necessary or desirable,  or that the Agent may reasonably  request,  in order to
create,  preserve,  perfect,  confirm or validate the  security  interest of the
Agent in the Collateral, to enable the Agent to obtain the full benefits of this
Security  Agreement  or to enable it to exercise  and enforce any of its rights,
powers and remedies hereunder,  including, without limitation, its right to take
possession of the Collateral.

(c) Signature. To the fullest extent permitted by law, the Debtor authorizes the
Agent to sign and file  financing and  continuation  statements  and  amendments
thereto with respect to the Collateral without its signature thereon.

Section 4.03. Change of Name, Identity or Structure.  The Debtor will not change
its name, identity or corporate structure in any manner and, except as set forth
on  Schedule  3.6,  will not conduct its  business  under any trade,  assumed or
fictitious  name unless it shall have given the Agent at least  forty-five  (45)
days'  prior  written  notice  thereof  and shall have taken all action (or made
arrangements to take such action  substantially  simultaneously with such change
if it is  impossible  to take such action in advance)  necessary  or  reasonably
requested  by the  Agent  to  amend  any  financing  statement  or  continuation
statement relating to the security interests granted hereby in order to preserve
such  security  interests  and to  effectuate  or maintain the priority  thereof
against all Persons.

Section 4.04.  Place of Business and Collateral.  The Debtor will not change the
location of (i) its places of business, (ii) its chief executive office or (iii)
the  office or other  locations  where it keeps or holds any  Collateral  or any
records relating thereto from the applicable  location listed on Schedule 3.4 or
3.5 unless,  prior to such change, it notifies the Agent forty-five (45) days in
advance of such change,  makes all UCC filings required by Section 4.2 and takes
all other action necessary or that the Agent may reasonably request to preserve,
perfect,  confirm and protect the security  interests granted hereby. The Debtor
will in no event  change the  location of any  Collateral  if such change  would
cause the security  interest granted hereby in such Collateral to lapse or cease
to be  perfected.  The Debtor  will at all times  maintain  its chief  executive
office within one of the forty-eight contiguous states in which Article 9 of the
uniform commercial code is in effect.

Section  4.05.  Fixtures.  The Debtor will not permit any  Equipment to become a
fixture  unless it shall  have  given the  Agent at least ten (10)  days'  prior
written  notice  thereof and shall have taken all such action and  delivered  or
caused to be delivered to the Agent all  instruments  and documents,  including,
without  limitation,  waivers and subordination  agreements by any landlords and
mortgagees, and filed all financing statements necessary or reasonably requested
by the Agent, to preserve and protect the security  interest  granted herein and
to effectuate or maintain the priority  thereof  against all Persons;  provided,
however,  that,  so long as no Event of  Default or  Potential  Event of Default
shall have  occurred  and be  continuing,  the Debtor  shall not be obligated to
comply with the provisions of this Section 4.5 with respect to the first $50,000
of Equipment (determined based on the then fair market value thereof).

Section 4.06.  Maintenance of Records.  The Debtor will keep and maintain at its
own cost and expense complete books and records relating to the Collateral which
are satisfactory to the Agent  including,  without  limitation,  a record of all
payments received and all credits granted with respect to the Collateral and all
of its other  dealings with the  Collateral.  The Debtor will mark its books and
records pertaining to the Collateral to evidence this Security Agreement and the
security interests granted hereby.  For the Agent' further security,  the Debtor
agrees  that the Agent  shall  have a special  property  interest  in all of the
Debtor's  books and records  pertaining to the  Collateral  and the Debtor shall
deliver  and  turn  over any  such  books  and  records  to the  Agent or to its
representatives at any time on demand of the Agent.

Section  4.07.  Compliance  with Laws The  Debtor  will  comply in all  material
respects with all acts, rules,  regulations,  orders,  decrees and directions of
any government or any state or local government  applicable to the Collateral or
any part  thereof or to the  operation of the  Debtor's  business  except to the
extent that the failure to comply  would not have a material  adverse  effect on
the  financial or other  condition of the Debtor;  provided,  however,  that the
Debtor may contest any act, rule, regulation,  order, decree or direction in any
reasonable  manner which shall not, in the sole opinion of the Agent,  adversely
affect the Agent's  rights or, in the case of  Collateral  located at a facility
identified on Schedule 3.7 hereto,  the first priority of its security  interest
in the Collateral.

Section 4.08. Payment of Taxes. The Debtor will pay promptly when due all taxes,
assessments and governmental charges or levies imposed upon the Collateral or in
respect of its income or  profits  therefrom,  as well as all claims of any kind
(including claims for labor, materials and supplies), except that no such charge
need be paid if (i) the  validity  thereof is being  contested  in good faith by
appropriate  proceedings and (ii) such charge is adequately  reserved against in
accordance  with  generally  accepted  accounting  principles,  as  consistently
applied.

Section 4.09.  Compliance with Terms of Accounts and Contracts.  The Debtor will
perform and comply in all material  respects with all of its  obligations  under
all agreements  relating to the Collateral to which it is a party or by which it
is bound.

Section  4.10.  Limitation on Liens on  Collateral.  The Debtor will not create,
permit or suffer to exist,  and will  defend  the  Collateral  and the  Debtor's
rights with respect  thereto  against and take such other action as is necessary
to  remove  any  Lien,  security  interest,  encumbrance,  or claim in or to the
Collateral other than the security interests created hereunder and such Liens to
the  extent  permitted  pursuant  to  Section  6.2(a)  of the  Revolving  Credit
Agreement.

Section 4.11. Limitations on Modifications of Receivables and Other Intangibles;
No Waivers or Extensions.  The Debtor will not (i) amend,  modify,  terminate or
waive any  provisions  of any material  Receivable  or Other  Intangible  in any
manner which might, when taken together with all such other Receivables or Other
Intangibles,  respectively,  materially  reduce the value of all  Receivables or
Other  Intangibles,  respectively,  in the  Collateral,  (ii)  fail to  exercise
promptly and  diligently  each and every  material right which it may have under
each  Receivable  and Other  Intangible  or (iii) fail to deliver to the Agent a
copy of each material demand,  notice or document received by it relating in any
way to any Receivable or Other Intangible.

Section  4.12.   Maintenance  of  Insurance.   The  Debtor  will  maintain  with
financially   sound  insurance   companies   licensed  to  do  business  in  the
jurisdictions  in which the  Collateral  is located  insurance  policies  on the
Inventory and Equipment in accordance  with the  provisions of Section 6.1(m) of
the Revolving Credit Agreement.

Section 4.13.  Limitations on  Dispositions  of Collateral.  The Debtor will not
directly or indirectly (through the sale of stock, merger or otherwise), without
the prior  written  consent of the Agent,  sell,  transfer,  lease or  otherwise
dispose of any of the Collateral,  or attempt, offer or contract to do so except
for (i) sales of Inventory in the ordinary course of its business for fair value
in  arm's-length  transactions  and  (ii) so long as no  Event  of  Default  (or
Potential  Event of Default) has occurred and is continuing,  dispositions  in a
commercially reasonable manner of Equipment which has become redundant, worn out
or obsolete or which should be replaced so as to improve  productivity,  so long
as the  proceeds  of any such  disposition  are (x) used to acquire  replacement
equipment  which has comparable or better utility and equivalent or better value
and which is subject to a first priority security interest in favor of the Agent
therein,  except  as  permitted  by  Section  6.2(a)  of  the  Revolving  Credit
Agreement, or (y) applied to repay the Obligations. The inclusion of Proceeds of
the Collateral under the security interests granted hereby shall not be deemed a
consent by the Agent to any sale or disposition of any Collateral  other than as
permitted by this Section 4.13.

Section 4.14. Further  Identification of Collateral.  The Debtor will furnish to
the Agent from time to time  statements and schedules  further  identifying  and
describing  the  Collateral  and  such  other  reports  in  connection  with the

the Agent if the value of the Collateral located at the facilities identified on
Schedule 3.7 hereto is less than 80% of the value of all of the Collateral.

Section  4.15.  Notices.  The  Debtor  will  advise  the Agent  promptly  and in
reasonable detail (i) of any Lien, security interest,  encumbrance or claim made
or  asserted  against  any of the  Collateral,  other  than,  unless  reasonably
requested  by the Agent,  Liens  permitted  by Section  6.2(a) of the  Revolving
Credit  Agreement,  (ii)  of  any  material  change  in the  composition  of the
Collateral,  and (iii) of the  occurrence  of any other event which would have a
material  adverse  effect on the  aggregate  value of the  Collateral  or on the
security interests granted to the Agent in this Security Agreement.

Section 4.16.  Change of Law. The Debtor shall promptly  notify the Agent of any
change in law known to it which (i) adversely  affects or will adversely  affect
the validity,  perfection or priority of the security  interests granted hereby,
(ii)  requires  or will  require a change in the  proceedings  to be followed in
order to maintain and protect such  validity,  perfection  and priority or (iii)
could result in the Agent not having a perfected security interest in any of the
Collateral.

Section 4.17.     Right of Inspection.

(a) Access to Books and Records. The Debtor shall,  following any request by the
Agent and upon reasonable  notice,  permit the Agent or its  representatives  to
have  full  and free  access  during  normal  business  hours to all the  books,
correspondence and records of the Debtor,  and the Agent or its  representatives

such discussions with officers,  employees and public  accountants of the Debtor
as the Agent may deem reasonably  necessary,  and the Debtor agrees to render to
the Agent, at the Debtor's cost and expense,  such clerical and other assistance
as  may  be  reasonably  requested  with  regard  thereto.  The  Agent  and  its
representatives  shall upon  reasonable  notice and during normal business hours
also  have the  right to enter  into  and  upon any  premises  where  any of the
Inventory or the  Equipment is located for the purpose of  inspecting  the same,
observing its use or protecting the interests of the Agent therein.

(b)  Audits.  The  Debtor  shall  permit  the  Lenders,   the  Agent  and  their
representatives  and advisors to review the operations of the Debtor and perform
the audits and  examinations  as  provided  in Section  6.1(l) of the  Revolving
Credit Agreement.

          Section  4.18.  Maintenance  of  Equipment.  The Debtor  will,  at its
          expense, maintain the Equipment in good operating condition,  ordinary
          wear and tear excepted.

Section 4.19.     Covenants Regarding Patent and Trademark Collateral.

(a)  Generally.  At  such  time as the  Debtor  shall  acquire  any  Patents  or
Trademarks,  it will comply with the terms,  covenants  and  warranties  of this
Section 4.19.

(b) Continued Use of Trademark.  The Debtor (either itself or through licensees)
will, unless the Debtor shall reasonably determine,  after consultation with the
Agent,  that a Trademark  is of  negligible  economic  value to the Debtor,  (i)
continue  to use each  Trademark  on each  and  every  Trademark  class of goods
applicable  to its current  products  and  services as  reflected in its current
catalogs,  brochures and price lists in order to maintain each Trademark in full
force and free from any claim of  abandonment  for non-use,  (ii) maintain as in
the past the quality of products  and  services  offered  under each  Trademark,
(iii) employ each Trademark with the appropriate  notice of  registration,  (iv)
not adopt or use any mark which is confusingly  similar to a colorable imitation
of any Trademark and (v) not (and not permit any licensee or sublicensee thereof
to) do any act or knowingly  omit to do any act whereby any Trademark may become
invalidated.

(c) No  Abandonment.  The Debtor will not,  unless the Debtor  shall  reasonably
determine,  after  consultation  with the Agent,  that a Patent is of negligible
economic  value to the  Debtor,  do any act,  or  knowingly  omit to do any act,
whereby any Patent may be abandoned or dedicated.

(d) Notice of Abandonment or Adverse Determinations. The Debtor shall notify the
Agent  immediately if it knows,  or has reason to know,  that any application or
registration  relating  to any  Patent or  Trademark  may  become  abandoned  or
dedicated,  or of any adverse determination or development  (including,  without
limitation,  the institution of, or any such determination or development in any
proceeding  in the United  States  Patent and  Trademark  Office or any court of
tribunal in any  country)  regarding  the  Debtor's  ownership  of any Patent or
Trademark, its right to register the same or keep and maintain the same.

(e) Filings After Notice to Agent.  In no event shall the Debtor,  either itself
or through any agent,  employee,  licensee or designee,  file an application for
registration  of any  Patent or  Trademark  with the  United  States  Patent and
Trademark  Office or any  similar  office or agency in any other  country or any
political  subdivision  thereof,  unless it promptly informs the Agent and, upon
request of the Agent, executes and delivers any and all agreements, instruments,
documents  and papers as the Agent may request to evidence the Agent's  security
interest in such Patent or Trademark and the goodwill and general intangibles of
the  Debtor  relating  thereto or  represented  thereby,  and the Debtor  hereby
constitutes the Agent its attorney-in-fact to execute and file all such writings
for the foregoing purposes, all such acts of such attorney being hereby ratified
and confirmed.

(f) Pursuit of Applications  and Maintenance of  Registrations.  The Debtor will
take all necessary  steps,  including,  without  limitation,  in any  proceeding
before the United States Patent and  Trademark  Office or any similar  office or
agency in any other country or any political  subdivision  thereof,  to maintain
and pursue each  application  (and to obtain the relevant  registration)  and to
maintain each  registration  of the Patents and  Trademarks,  including  without
limitation, filing of applications for renewal, affidavits of use and affidavits
of incontestability;  provided,  however, that no such Patent or Trademark shall
be required to be  maintained  or pursued to the extent such Patent or Trademark
is  determined  by the  Debtor,  after  consultation  with the  Agent,  to be of
negligible economic value to the Debtor.

(g) Notice of  Infringement.  If any of the Patent and  Trademark  Collateral is
infringed,  misappropriated  or  diluted  by a third  party,  the  Debtor  shall
promptly  notify the Agent after it learns thereof and shall,  unless the Debtor
shall reasonably determine,  after consultation with the Agent, that such Patent
and Trademark Collateral is of negligible economic value to the Debtor, promptly
sue for infringement, misappropriation of dilution, seek injunctive relief where
appropriate   and  recover   any  and  all   damages   for  such   infringement,
misappropriation  or  dilution,  or take such other  action as the Debtor  shall
reasonably deem appropriate  under the  circumstances to protect such Patent and
Trademark Collateral.

Section 4.20.  Termination  of Federal  Contracts.  With respect to each Federal
Contract in respect of which the Debtor is required to execute an  Assignment of
Federal  Contract in accordance with Section 4.21 hereof,  the Debtor shall give
prompt written  notice to the Agent if the U.S.  Government  shall  terminate or
threaten to  terminate  (whether  for  convenience  or default) any such Federal
Contract  with the Debtor  having a value  (including  unexercised  options)  of
$100,000 or more. In addition,  the Debtor shall give prompt  written  notice to
the Agent if the U.S.  Government  shall  terminate or threaten to terminate any
contract between the U.S.  Government and any other prime contractor under which
the  Debtor  is a  subcontractor  if the  value of such  subcontract  (including
unexercised  options) is $100,000 or more. Section 4.21. Federal Contracts.  The
Debtor shall  provide to the Agent,  as soon as reasonably  practicable  but not
later than  forty-five  (45) days  following the end of each Fiscal  Quarter,  a
report identifying each Federal Contract to which it is a party, having attached
thereto a copy of the first two pages of such Federal Contract and any amendment
thereto,  to the extent not previously  provided to the Agent. At the request of
the Agent (unless an Event of Default shall have occurred and be continuing,  in
which case no such request  shall be  required),  the Debtor  shall  execute and
deliver to the Agent an Assignment of Federal  Contract,  in  substantially  the
form of Exhibit A hereto (the "Assignment of Federal Contract"), and execute any
other  instruments  or take any other steps  required by the Agent in order that
all moneys due or to become due under such Federal  Contracts  shall be assigned
to the Agent and  notice  thereof  given  under the  Assignment  of Claims  Act,
including without limitation  delivery of Notices of Assignments with respect to
each Federal Contract as contemplated by Appendix A to Exhibit A hereto.

Section 4.22.  Reimbursement  Obligation.  Should the Debtor fail to comply with
the provisions of this Security Agreement, the Revolving Credit Agreement or any
other agreement relating to the Collateral such that the value of any Collateral
or the validity,  perfection,  rank or value of any security interest granted to
the  Agent  hereunder  or  thereunder  is  thereby   diminished  or  potentially
diminished or put at risk (as reasonably  determined by the Agent), the Agent on
behalf of the Debtor may, but shall not be required to,  effect such  compliance
on behalf of the Debtor,  and the Debtor shall  reimburse the Agent for the cost
thereof on demand,  and interest shall accrue on such  reimbursement  obligation
from the date the relevant  costs are incurred  until  reimbursement  thereof in
full at the Default Rate.

ARTICLE V.

                                      REMEDIES; RIGHTS UPON DEFAULT

Section 5.01. UCC Rights.  In the event that any portion of the  Obligations has
been declared or becomes due and payable in accordance with the Revolving Credit
Agreement or other Credit  Documents and such  Obligations have not been paid in
full,  the Agent may in addition to all other rights and remedies  granted to it
in this Security  Agreement and in any other  instrument or agreement  securing,
guarantying,  evidencing or relating to the Obligations, exercise (i) all rights
and  remedies of a secured  party under the UCC (whether or not in effect in the
jurisdiction  where  such  rights  are  exercised)  and  (ii) all  other  rights
available to the Agent at law or in equity.

          Section 5.02.  Payments on Collateral.  Without limiting the rights of
          the Agent under any other provision of this Security Agreement,  if an
          Event of Default shall occur and be continuing:

(i) all payments  received by the Debtor under or in connection  with any of the
Collateral  shall  be held by the  Debtor  in  trust  for the  Agent,  shall  be
segregated  from other funds of the Debtor and shall  forthwith  upon receipt by
the Debtor be turned  over to the  Agent,  in the same form as  received  by the
Debtor  (duly  indorsed  by the  Debtor  to the  Agent,  if  required  to permit
collection thereof by the Agent); and

(ii) all such  payments  received  by the  Agent  (whether  from the  Debtor  or
otherwise)  may, in the sole  discretion  of the Agent,  be held by the Agent as
collateral  security for, and/or then or at any time thereafter applied in whole
or in part by the Agent to the payment of, the expenses and the  Obligations  as
set forth in Section 5.11 hereof.

Section 5.03.  Possession of Collateral.  In  furtherance of the foregoing,  the
Debtor  expressly  agrees  that,  if an  Event of  Default  shall  occur  and be
continuing, the Agent may (i) by judicial powers, or without judicial process if
it can be done without breach of the peace, enter any premises where any of such
Collateral is or may be located and,  without  charge or liability to the Agent,
seize and remove such  Collateral from such premises and (ii) have access to and
use of the Debtor's books and records relating to such Collateral.

Section 5.04.     Sale of Collateral; Notice.

(a) Sale of Collateral.  The Debtor expressly agrees that if an Event of Default
shall occur and be continuing, the Agent, without demand of performance or other
demand or notice of any kind (except the notice  specified below of the time and
place of any public or private  sale) to or upon the Debtor or any other  Person
(all of which  demands  and/or  notices are hereby  waived by the  Debtor),  may
forthwith (i) apply the cash, if any, then held by it as collateral as specified
in Section  5.11 hereof and (ii) if there shall be no cash or such cash shall be
insufficient to pay the Obligations in full, collect,  receive,  appropriate and
realize upon the Collateral,  and/or sell, assign,  give an option or options to
purchase or otherwise  dispose of and deliver the  Collateral (or contract to do
so) or any part thereof in one or more parcels (which need not be in round lots)
at public or  private  sale,  at any  office of the Agent or  elsewhere  in such
manner as is  commercially  reasonable and, as the Agent may deem best, for cash
or on credit or for future delivery  without  assumption of any credit risk. The
Agent shall have the right upon any such public sale,  and, if the Collateral is
of a type customarily  sold in a recognized  market or is of a type which is the
subject of widely distributed  standard price quotations,  upon any such private
sale or sales,  to purchase the whole or any part of the Collateral so sold, and
thereafter to hold the same,  absolutely and free from any right or claim of any
kind. To the extent  permitted by applicable  law, the Debtor waives all claims,
damages  and  demands  against  the  Agent  arising  out  of  the   foreclosure,
repossession, retention or sale of the Collateral.

(b) Notice of Sale. Unless the Collateral threatens to decline speedily in value
or is of a type  customarily sold on a recognized  market,  the Agent shall give
the Debtor  ten (10)  days'  written  notice of its  intention  to make any such
public or private sale or sale at a broker's board or on a securities  exchange.
Such  notice  shall (i) in the case of a public  sale,  state the time and place
fixed  for  such  sale,  (ii) in the  case of sale at a  broker's  board or on a
securities  exchange,  state the board or  exchange  at which such sale is to be
made and the day on which the  Collateral,  or the portion  thereof  being sold,
will first be offered  for sale and (iii) in the case of a private  sale,  state
the day after which such sale may be consummated.  The Agent shall not obligated
to make any such sale  pursuant  to any such  notice.  The Agent may adjourn any
public or private  sale or cause the same to be  adjourned  from time to time by
announcement at the time and place fixed for the sale, and such sale may be made
at any time or place to which the same may be so  adjourned.  In the case of any
sale of all or any part of the Collateral on credit or for future delivery,  the
Collateral  so sold may be retained by the Agent until the selling price is paid
by the purchaser thereof, but the Agent shall not incur any liability in case of
the failure of such purchase to take up and pay for the  Collateral so sold and,
in the case of such failure, such Collateral may again be sold upon like notice.

(c) Special  Provisions  Relating to Sales of Securities.  The Debtor recognizes
that  the  Agent  may be  unable  to  effect  a  public  sale  of any or all the
Collateral  constituting a "security" (as such term is defined in the Securities
Act) by reason of  certain  prohibitions  contained  in the  Securities  Act and
applicable state securities laws or otherwise, and may be compelled to resort to
one or more private sales thereof to a restricted  group of purchasers that will
be obliged to agree,  among other things,  to acquire such  securities for their
own account for  investment  and not with a view to the  distribution  or resale
thereof.  The Debtor  acknowledges  and agrees  that any such  private  sale may
result in prices and other terms less  favorable than if such sale were a public
sale and, notwithstanding such circumstances,  agrees that any such private sale
shall be deemed to have been made in a commercially reasonable manner. The Agent
shall be under no obligation to delay a sale of any of Collateral constituting a
security  for the  period of time  necessary  to permit  the  issuer  thereof to
register  such  securities  for public sale under the  Securities  Act, or under
applicable state securities laws, even if such issuer would agree to do so.

Section 5.05.  Rights of Purchasers.  Upon any sale of the  Collateral  (whether
public or  private),  the Agent  shall  have the right to  deliver,  assign  and
transfer  to the  purchaser  thereof  the  Collateral  so sold.  Each  purchaser
(including  the  Agent)  at any such  sale  shall  hold the  Collateral  so sold
absolutely,  free from any claim or right of whatever kind, including any equity
or right of redemption of the Debtor who, to the extent permitted by law, hereby
specifically waives all rights of redemption, including, without limitation, any
right to redeem the Collateral  under Section 9-506 of the UCC, and any right to
a judicial or other stay or approval  which it has or may have under any law now
existing or hereafter adopted.

Section 5.06.     Additional Rights of the Agent.

(a) Right to Maintain Proceedings.  The Agent (i) shall have the right and power
to institute and maintain such suits and proceedings as it may deem  appropriate
to protect and enforce the rights  vested in it by this  Security  Agreement and
(ii) may proceed by suit or suits at law or in equity to enforce such rights and
to foreclose  upon the  Collateral and to sell all or, from time to time, any of
the   Collateral   under  the  judgment  or  decree  of  a  court  of  competent
jurisdiction.

(b)  Appointment  of  Receiver.  The Agent  shall,  to the extent  permitted  by
applicable law,  without notice to the Debtor to any party claiming  through the
Debtor,  without regard to the solvency or insolvency at such time of any Person
then liable for the  payment of any of the  Obligations,  without  regard to the
then value of the Collateral and without requiring any bond from any complainant
in such  proceedings,  be entitled as a matter of right to the  appointment of a
receiver  or  receivers  (who may be the  Agent) of the  Collateral  or any part
thereof,  pending  such  proceedings,  with such powers as the court making such
appointment  shall  confer,  and to the  entry  of an order  directing  that the
profits, revenues and other income of the property constituting the whole or any
part of the Collateral be segregated,  sequestered and impounded for the benefit
of the Agent,  and the Debtor  irrevocably  consents to the  appointment of such
receiver or receivers and to the entry of such order.

(c) No Duty to  Exercise  Rights.  In no event  shall the Agent have any duty to
exercise any rights or take any steps to preserve the rights of the Agent in the
Collateral,  nor shall the Agent be liable to the Debtor or any other Person for
any loss caused by the Agent's failure to meet any obligation imposed by Section
9-207 of the UCC or any successor provision. Without limiting the foregoing, the
Agent  shall be deemed to have  exercised  reasonable  care in the  custody  and
preservation  of the  Collateral in its possession if the Collateral is accorded
treatment  substantially equal to that which the Agent accords its own property,
it being understood that the Agent shall not have any duty or responsibility for
(i) ascertaining or taking action with respect to calls, conversions, exchanges,
maturities,  tenders or other matters relative to any Collateral, whether or not
the Agent has or is deemed to have knowledge of such matters, or (ii) taking any
necessary  steps to preserve  rights  against any  parties  with  respect to any
Collateral.

Section 5.07.     Remedies Not Exclusive, etc.

(a) Remedies Not Exclusive. No remedy conferred upon or reserved to the Agent in
this  Security  Agreement  is intended to be  exclusive  of any other  remedy or
remedies,  but every such remedy shall be cumulative and shall be in addition to
every other  remedy  conferred  herein or now or  hereafter  existing at law, in
equity or by statute.

(b)  Restoration  of Rights.  If the Agent shall have  proceeded  to enforce any
right,  remedy or power under this Security Agreement and the proceeding for the
enforcement  thereof shall have been discontinued or abandoned for any reason or
shall have been  determined  adversely  to the  Agent,  the Debtor and the Agent
shall,   subject  to  any  determination  in  such  proceeding,   severally  and
respectively  be  restored  to their  former  positions  and  rights  under this
Security Agreement,  and thereafter all rights, remedies and powers of the Agent
shall continue as though no such proceedings had been taken.

(c)  Enforcement.  All rights of action  under this  Security  Agreement  may be
enforced by the Agent without the  possession of any  instrument  evidencing any
Obligation or the production  thereof at any trial or other proceeding  relative
thereto, and any suit or proceeding  instituted by the Agent shall be brought in
its name and any judgment shall be held as part of the Collateral.

Section 5.08.     Waiver and Estoppel.

(d) No Actions to Impede Sale of Collateral. The Debtor agrees, to the extent it
may lawfully do so, that it will not at any time in any manner  whatsoever claim
or take the benefit or advantage of any appraisal,  valuation,  stay, extension,
moratorium,  turnover or redemption  law, or any law permitting it to direct the
order in which the  Collateral  shall be sold,  now or at any time  hereafter in
force  which  may  delay,   prevent  or  otherwise  affect  the  performance  or
enforcement  of this  Security  Agreement,  and  hereby  waives  all  benefit or
advantage of all such laws. The Debtor covenants that it will not hinder,  delay
or impede  the  execution  of any power  granted  to the Agent in this  Security
Agreement, any Assignment of Federal Contract or any other Credit Document.

(e) Collateral Sold As An Entirety. The Debtor, to the extent it may lawfully do
so, on behalf of itself and all who claim through or under it, including without
limitation any and all  subsequent  creditors,  vendees,  assignees and lienors,
waives  and  releases  all  rights to demand or to have any  marshalling  of the
Collateral upon any sale, whether made under any power of sale granted herein or
pursuant to judicial  proceedings or under any foreclosure or any enforcement of
this Security Agreement,  and consents and agrees that all of the Collateral may
at any such sale be offered and sold as an entirety.

(f) Waiver of  Notices.  The Debtor  waives,  to the  extent  permitted  by law,
presentment,  demand,  protest  and any notice of any kind  (except  the notices
expressly required hereunder) in connection with this Security Agreement and any
action taken by the Agent with respect to the Collateral.

Section 5.09.     Power of Attorney; Powers Coupled With An Interest.

(g) Power of Attorney.  Without limiting any other right granted hereunder,  the
Debtor hereby irrevocably constitutes and appoints the Agent, with full power of
substitution,  as its true and  lawful  attorney-in-fact  with full  irrevocable
power and  authority in the place and stead of the Debtor and in the name of the
Debtor  or in its  own  name,  from  time  to  time  in the  Agent's  reasonable
discretion,  for the  purpose  of  carrying  out  the  terms  of  this  Security
Agreement,  to take any and all  appropriate  action and to execute  any and all
documents and instruments  which may be necessary or desirable to accomplish the
purpose of this Security  Agreement and,  without limiting the generality of the
foregoing,  hereby gives the Agent the power and right, on behalf of the Debtor,
without notice to or assent by the Debtor, to do the following:

          (i) to pay or  discharge  taxes,  liens,  security  interests or other
          encumbrances levied or placed on or threatened against the Collateral;

(ii) to effect  any  repairs  or any  insurance  called for by the terms of this
Security  Agreement or any other Credit Document,  and to pay all or any part of
the premiums therefor and the costs thereof;

(iii) upon the occurrence and  continuance of any Event of Default and otherwise
to the  extent  provided  in this  Security  Agreement,  (A) to direct any party
liable for any payment  under any of the  Collateral  to make payment of any and
all moneys due and to come due thereunder  directly to the Agent or as the Agent
shall direct,  (B) to receive  payment of and receipt for, and to demand and sue
for, any and all moneys,  claims and other  amounts due and to become due at any
time in respect of or arising out of the Collateral, (C) to sign and indorse and
receive,  take, assign and deliver, any checks,  notes,  drafts,  negotiable and
non-negotiable  instruments,  any invoices,  freight or express bills,  bills of
lading,  storage or warehouse  receipts,  drafts against  debtors,  assignments,
verifications  and  notices in  connection  with  accounts  and other  documents
relating to the  Collateral,  (D) to  commence,  settle,  compromise,  compound,
prosecute,  defend or adjust any claim,  suit, action or proceeding with respect
to, or in connection  with, the  Collateral,  (E) to sell,  transfer,  assign or
otherwise  deal in or with the  Collateral  or any part  thereof,  as fully  and
effectively  as if the Agent were the absolute  owner  thereof and (F) to do, at
its option,  but at the expense of the Debtor, at any time or from time to time,
all acts and things  which the Agent deems  necessary  to  protect,  preserve or
realize upon the Collateral and the Agent's security interest therein,  in order
to effect the intent of this Security Agreement, all as fully and effectively as
the Debtor might do.

(h) Powers Coupled With an Interest.  All authorizations and agencies granted or
provided  herein with respect to the  Collateral,  including the powers  granted
under clause (a) of this Section 5.9, are irrevocable and powers coupled with an
interest.

Section 5.10. Certain Provisions Relating to Securities.  Solely with respect to
any Collateral  constituting a "security" (as defined in the Securities Act), if
an Event of Default shall have occurred and be continuing,  all such  securities
(as defined in the Securities Act)  constituting a part of the Collateral shall,
at the  request  of the  Agent,  be  registered  in the name of the Agent or its
nominee,  and the Agent or its nominee may  thereafter  exercise (i) all voting,
corporate and other rights,  powers and privileges pertaining to such Collateral
at any meeting of shareholders of the issuer thereof or otherwise,  and (ii) any
and all  rights of  conversion,  exchange,  subscription  and any other  rights,
privileges or options  pertaining to such  Collateral as if it were the absolute
owner  thereof  (including,  without  limitation,  the right to  exchange at its
discretion  any  and  all  such  Collateral  upon  the  merger,   consolidation,
reorganization, recapitalization or other fundamental change in the structure of
any such  issuer,  or upon the exercise by the Debtor or the Agent of any right,
privilege or option pertaining to such Collateral,  and in connection therewith,
the right to deposit and deliver any and all such Collateral with any committee,
depositary, transfer agent, registrar or other designated agency upon such terms
and conditions as it may determine), all without liability except to account for
property  actually  received  by it and except as  provided  in  Section  5.6(c)
hereof,  but the Agent  shall  have no duty to the Debtor to  exercise  any such
right, privilege or option and shall not be responsible for any failure to do so
or delay in so doing.

          Section 5.11.  Application of Monies.  The proceeds of any sale of, or
          other  realization  upon, all or any part of the  Collateral  shall be
          applied by the Agent in the following order of priority:

                  first,  to  payment  of the  expenses  of such  sale or  other
realization,  including reasonable  compensation to the Agent and its agents and
counsel,  and all  expenses,  liabilities  and advances  incurred or made by the
Agent, its agents and counsel in connection  therewith or in connection with the
care, safekeeping or otherwise of any or all of the Collateral;

          second, to payment of the Obligations,  in such order as the Agent may
          elect; and

                  third, any surplus then remaining shall be paid to the Debtor,
or its  successors  or assigns,  or to  whomsoever  may be lawfully  entitled to
receive the same (including  pursuant to Section 9-504(1)(C) of the UCC) or as a
court of competent jurisdiction may direct.

ARTICLE VI.

                                              MISCELLANEOUS

Section 6.01. Notices. All notices, requests and other communications to a party
hereunder  shall be in writing  and shall be given to such party at its  address
set forth on the  signature  page hereof or such other address as such party may
hereafter  specify for that  purpose by notice to the other.  Each such  notice,
request or other  communication shall be effective (i) in the case of telephonic
notice (to the extent  expressly  permitted  hereunder),  when made, (ii) in the
case of notice delivered by overnight  express  courier,  one Business Day after
the Business Day such notice was delivered to such courier, (iii) in the case of
notice  delivered by first class mail, three Business Days after being deposited
in the mail,  postage  prepaid,  return receipt  requested,  (iv) in the case of
notice by hand,  when  delivered,  or (v) in the case of notice by any customary
means of telecommunication, when sent provided confirmation of receipt or answer
back has been  received,  in each  case if  addressed  to any  party  hereto  as
provided  herein.  Rejection or refusal to accept,  or the  inability to deliver
because of a changed address of which no notice was given,  shall not affect the
validity of notice given in accordance with this section.

Section 6.02.  No Waiver;  Cumulative  Remedies.  The Agent shall not by any act
(except by a written  instrument  pursuant  to Section  6.3 hereof) be deemed to
have waived any right or remedy hereunder. No failure to exercise, nor any delay
in exercising,  on the part of the Agent any right, power or privilege hereunder
shall operate as a waiver thereof.  No single or partial  exercise of any right,
power or  privilege  hereunder  shall  preclude  any other or  further  exercise
thereof or the exercise of any other right, power or privilege.  A waiver by the
Agent  of any  right  or  remedy  hereunder  on any one  occasion  shall  not be
construed as a bar to any right or remedy which the Agent would  otherwise  have
on any future occasion.  The rights and remedies herein provided are cumulative,
may be  exercised  singly or  concurrently  and are not  exclusive  of any other
rights or remedies provided by law.

Section 6.03.  Amendments  and Waivers.  None of the terms or provisions of this
Security Agreement may be amended,  supplemented or otherwise modified except by
a written  instrument  executed by the Debtor and the Agent;  provided  that any
provision of this  Security  Agreement may be waived by the Agent in a letter or
agreement  executed by the Agent or by telex or facsimile  transmission from the
Agent.

Section 6.04.  Successors and Assigns. The provisions of this Security Agreement
shall be binding  upon and inure to the benefit of the parties  hereto and their
respective  successors and assigns;  provided,  however, that the Debtor may not
assign or transfer any of its rights or obligations  hereunder without the prior
written consent of the Agent.

          Section 6.05. Governing Law. THIS SECURITY AGREEMENT SHALL BE GOVERNED
          BY AND CONSTRUED IN ACCORDANCE  WITH THE LAWS OF THE  COMMONWEALTH  OF
          VIRGINIA,  OTHER  THAN ITS LAWS  RESPECTING  CHOICE OF LAW OTHER  THAN
          THOSE CONTAINED IN THE UCC.

Section 6.06.     Limitation by Law; Severability.

(i) All rights,  remedies and powers provided in this Security  Agreement may be
exercised  only to the extent  that the  exercise  thereof  does not violate any
applicable  provision of law, and all the provisions of this Security  Agreement
are intended to be subject to all applicable  mandatory  provisions of law which
may be controlling  and to be limited to the extent  necessary so that they will
not render this Security Agreement  invalid,  unenforceable in whole or in part,
or not entitled to be recorded,  registered or filed upon the  provisions of any
applicable law.

(j) If any provision hereof is invalid and  unenforceable  in any  jurisdiction,
then, to the fullest extent  permitted by law, (i) the other  provisions  hereof
shall  remain  in full  force  and  effect  in such  jurisdiction  and  shall be
liberally  construed in favor of the Agent in order to carry out the  intentions
of the parties  hereto as nearly as may be possible and (ii) the  invalidity  or
unenforceability  of any provision hereof in any  jurisdiction  shall not affect
the validity or enforceability of such provision in any other jurisdiction.

Section  6.07.  Counterparts.  This  Security  Agreement  may be executed in any
number of counterparts and by different parties hereto on separate counterparts,
each complete set of which, when so executed and delivered by all parties, shall
be an original,  but all such counterparts shall together constitute but one and
the same instrument.

Section 6.08. Expenses of the Agent. The Debtor shall pay to the Agent from time
to time upon demand,  all of the costs and expenses incurred by the Agent or any
Lender (including,  without limitation, the reasonable fees and disbursements of
counsel  and any  amounts  payable  by the  Agent or any  Lender to any of their
respective   agents)  (i)  arising  in  connection   with  the   administration,
modification, amendment, waiver or termination of this Security Agreement or any
document or agreement  contemplated hereby or any consent or waiver hereunder or
thereunder  or (ii)  incurred  in  connection  with the  administration  of this
Security  Agreement,  or any document or agreement  contemplated  hereby,  or in
connection  with the  administration,  sale or other  disposition  of Collateral
hereunder  or  under  any  document  or  agreement  contemplated  hereby  or the
preservation,  protection or defense of the rights of the Agent or any Lender in
and to the Collateral.

Section  6.09.  Indemnification.   The  Debtor  shall  at  all  times  hereafter
indemnify, hold harmless and, on demand, reimburse the Agent and the Lenders and
their  respective  subsidiaries,   affiliates,  successors,  assigns,  officers,
directors,   employees  and  agents,  and  their  respective  heirs,  executors,
administrators, successors and assigns (all of the foregoing parties, including,
but not limited to, the Agent, being hereinafter collectively referred to as the
"Indemnities" and individually as an "Indemnitee") from, against and for any and
all liabilities,  obligations,  claims, damages, actions,  penalties,  causes of
action, losses, judgments, suits, costs, expenses and disbursements,  including,
without  limitation,  attorney's  fees  (any  and  all  of the  foregoing  being
hereinafter  collectively referred to as the "Liabilities" and individually as a
"Liability")  which  the  Indemnitees,  or  any  of  them,  might  be or  become
subjected, by reason of, or arising out of the preparation, execution, delivery,
modification,  administration  or enforcement  of, or performance of the Agent's
rights  under,  this  Security  Agreement or any other  document,  instrument or
agreement  contemplated  hereby or executed in  connection  herewith;  provided,
however, that the Debtor shall not be liable to any Indemnitee for any Liability
caused solely by the gross negligence or willful  misconduct of such Indemnitee.
In no event shall any  Indemnitee,  as a condition to enforcing its rights under
this Section 6.9 or  otherwise,  be obligated to make a claim  against any other
Person (including,  without  limitation,  the Agent) to enforce its rights under

6 shall survive any such termination.

Eastern  District of Virginia,  and, by execution  and delivery of this Security
Agreement,   the  Debtor  (a)  accepts,   generally  and  unconditionally,   the
nonexclusive  jurisdiction  of such courts and any related  appellate  court and
irrevocably  agrees to be bound by any judgment  rendered  thereby in connection
with any Credit Agreement Related Claim and (b) irrevocably waives any objection
it may now or hereafter have as to the venue of any such  proceeding  brought in
such a court or that such a court is an  inconvenient  forum.  The Debtor hereby
waives personal  service of process and consents that service of process upon it
may be made by certified or registered mail,  return receipt  requested,  at its

requested),  the fifth (5th) Business Day after such service is deposited in the
mail. Nothing herein shall affect the right of the Agent to serve process in any
other  manner  permitted  by law or shall  limit the right of the Agent to bring
proceedings  against  the  Debtor in the courts of any other  jurisdiction.  Any
judicial proceeding by the Debtor against the Agent relating to or involving any
Credit  Agreement  Related Claim hereby shall be brought only in a court located
in the Commonwealth of Virginia,  County of Fairfax, or the Federal court in the
Eastern  District of Virginia.  THE DEBTOR AND THE AGENT HEREBY  UNCONDITIONALLY
WAIVE  TRIAL  BY JURY IN ANY  JUDICIAL  PROCEEDING  TO WHICH  THEY  ARE  PARTIES
INVOLVING ANY CREDIT AGREEMENT RELATED CLAIM.

herein or resulting or arising out of this Security  Agreement shall, as between
the Agent and the Lenders,  be governed by the Revolving Credit Agreement and by
such other  agreements with respect thereto as may exist from time to time among
them, but, as between the Agent and the Debtor,  the Agent shall be conclusively
presumed to be acting as agent for the Lenders with full and valid  authority so
to act or refrain from acting, and the Debtor shall not be under any obligation,
or entitlement, to make any inquiry respecting such authority.

                         ASSIGNMENT OF FEDERAL CONTRACT


                  This  ASSIGNMENT OF FEDERAL  CONTRACT,  dated as of _____,  __
(the  "Agreement"),  is  made  by  FIELDSTON  PUBLICATIONS,   INC.,  a  Maryland
corporation (the "Assignor"), in favor of NATIONSBANK,  N.A., a national banking
association (the "Agent"), in its capacity as Agent for the lenders from time to
time a party to the  Revolving  Credit  Agreement  (as  defined in the  Security
Agreement referred to below).

                                               W I T N E S S E T H:

                  WHEREAS,   the  Assignor  has  secured   certain   obligations
undertaken  by Hagler  Bailly,  Inc.  pursuant to the  provisions  of a Security
Agreement,  dated as of  ___________________,  ____ (as the same may be amended,
supplemented or otherwise modified from time to time, the "Security Agreement"),
by and between the Assignor and the Agent; and

                  WHEREAS,  the  Assignor  is a party to,  and from time to time
will  become  entitled  to  receive  moneys  under and by  virtue  of, a certain
contract  with,  involving or for the benefit of the United States of America or
any department,  agency or  instrumentality  thereof (herein  referred to as the
"Government"),  designated  as  Contract  Number  _______  entered  into  by the
Assignor and the Government on ________ __, 19__ (which contract,  together with
all additions, change orders, supplements, amendments, renewals, extensions, and
modifications  thereto now or hereafter in effect, are hereinafter  collectively
called the "Contract"); and

                  WHEREAS,  pursuant to the Security Agreement, the Assignor has
undertaken to effectuate the  assignment(s)  and other actions  contemplated  by
this Agreement.

                  NOW,  THEREFORE,  in  consideration  of the premises and other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the Assignor covenants and agrees as follows:

         1. Incorporation By Reference. The provisions of the Security Agreement
are  incorporated  herein by  reference,  and the terms  defined in the Security
Agreement are used herein with the same meanings.

         2.  Representations.  The Assignor represents and warrants to the Agent
that (a) the Contract is legal,  valid and binding on the  Assignor  and, to its
knowledge,  the other parties thereto,  is in full force and effect,  and is not
evidenced  by any  chattel  paper or  instrument,  (b) upon due  filing  of this
Agreement,  together  with a Notice of Assignment  substantially  in the form of
Appendix A hereto with the authorized representative, the execution and delivery
of this Agreement does not violate and is not in conflict with the provisions of
the  Contract,  (c) there has been no default on the part of the Assignor or any
other party to the Contract, (d) the Assignor has made no previous assignment of
the  Contract to any person and knows of no fact or defense that will render the
moneys due or to be due  thereunder  uncollectible,  (e) no financing  statement
covering  the  Contract  is on  file  in  any  public  office  except  financing
statements in favor of the Agent,  (f) no set-off or  counterclaim to any moneys
due or to become  due  under the  Contract  exists  on the date  hereof,  and no
agreement  has been made with any person  under which any  deduction or discount
may be claimed,  and (g) the address of the office where the Assignor  keeps its
records concerning the Contract is ____________________.

         3. Collateral. As security and collateral for the payment of all of the
Obligations  (defined in the Security  Agreement)  and for  performance  of, and
compliance  with,  by the  Assignor,  all of the terms,  covenants,  conditions,
stipulations,  and  agreements  contained in this  Agreement and in the Security
Agreement,  the Assignor hereby assigns to the Agent,  and grants to the Agent a
lien on and  security  interest  in,  all  moneys  and claims for moneys now and
hereafter  due and to  become  due to the  Assignor  under or by  reason  of the
Contract,  together  with all  cash and  non-cash  proceeds  thereof;  provided,
however,  that nothing  contained  herein shall impose upon the Agent any of the
obligations or liabilities of the Assignor under the Contract.

         4. Covenants. Until payment and performance in full of the Obligations,
the Assignor covenants as follows:

(k) The  Assignor  shall  place  on any and all  vouchers,  invoices,  or  other
instruments demanding payment under the Contract the direction that such payment
is to be made to the Agent in accordance with Section 5 of this Agreement.

(l) The Assignor shall promptly upon request execute,  acknowledge,  and deliver
any  notice,  financing  statement,   renewal,   affidavit,   deed,  assignment,
continuation statement,  security agreement,  certificate,  or other document as
the  Agent  may  require  in  order to  perfect,  preserve,  maintain,  protect,
continue, and/or extend the assignment, lien, and security interest of the Agent
under this  Agreement and its priority.  The Assignor  shall pay to the Agent on
demand all taxes,  costs, and expenses  incurred by the Agent in connection with
the  preparation,  execution,  recording,  and  filing of any such  document  or
instrument  mentioned  aforesaid,  and such taxes,  costs,  and  expenses  shall
constitute  and become a part of the  Obligations.  A carbon,  photographic,  or
other  reproduction  of  a  security  agreement  or  a  financing  statement  is
sufficient as a financing statement.

(m) The Assignor shall fully,  promptly,  and faithfully comply with and perform
its  obligations  and duties  under the  Contract in  accordance  with the terms
thereof and will make no changes or  amendments  to the Contract or terminate or
cancel the  Contract  without the prior  written  consent of the Agent except as
permitted by the Security  Agreement.  In the event that any change,  amendment,
termination  or  cancellation  of  the  Contract  is  made  or  effected  by the
Government,  the Assignor  will  promptly  notify the Agent thereof and promptly
furnish to the Agent a copy of any  document or  agreement  evidencing  any such
change, amendment, termination, or cancellation.

(n)      The Assignor will promptly

          (i)  furnish to the Agent all  information  received  by the  Assignor
          affecting the moneys due and to become due under the Contract,

          (ii) inform the Agent of any delay in  performance  of, or claims made
          in regard to, the Contract, and

(iii) notify the Agent in writing of the failure of any party to the Contract to
perform any of its  obligations  thereunder and any rejection of any performance
rendered by the Assignor under or in connection with the Contract.

(o) The  Assignor  will at all times  keep  accurate  and  complete  records  of
performance  by the Assignor  under the  Contract,  and the Agent and its agents
shall have the right,  during normal business hours and upon reasonable  advance
notice,  to call at the place or places of business of the Assignor at intervals
to be  determined  by the Agent,  and without  hindrance  or delay,  to inspect,
audit,  check,  and make extracts  from the books,  records,  journals,  orders,
receipts,  correspondence,  and other data  relating  to the  Contract or to any
other transactions between the parties hereto related to the Contract.

         5. Payments. The Assignor hereby authorizes,  empowers, and directs the
Government to draw all checks,  drafts,  or other  instruments  representing the
payments of money due the Assignor under the Contract  (herein called the "Items
of Payment") to the order of  NationsBank,  N.A.,  assignee of Assignor,  and to
send  the  same  (i)  if by  mail,  to ,  (ii)  if by  electronic  transfer,  to
NationsBank, N.A. for the account of ________________, Bank Account #__________,
Agent ABA#_________,  or (iii) if by wire transfer, to NationsBank, N.A. for the
account of  _________________________,  Bank Account #_______,  ABA#___________.
If, despite this  direction,  any  instruments or checks  representing  payments
should be delivered to the Assignor,  the Assignor will immediately  endorse and
deliver such  instruments or checks to the order of the Agent. The Assignor does
hereby  irrevocably  (subject  to  revocation  with the  consent  of the  Agent)
designate and appoint (which appointment is coupled with an interest) the Agent,
and the Agent's  successors in interest by operation of law, the Assignor's true
and  lawful  attorney  with  power  irrevocable  for  the  Assignor  and  in the
Assignor's  name,  place,  and  stead,  but at the sole cost and  expense of the
Assignor,  to receive,  endorse,  and collect all Items of Payment,  and to ask,
demand,  receive,  receipt,  and give acquittances for any and all amounts which
may be payable  or which  become due and  payable  by the  Government  under the
Contract,  and in the Agent's  discretion to file any claim or to take any other
action  or  proceeding,  either  in the  Agent's  own name or in the name of the
Assignor or otherwise,  which to the Agent or any successor in interest  thereof
may seem  necessary  or  desirable in order to collect or endorse the payment of
any and all amounts now due or owing or which may  hereafter be or become due or
owing on account of the  Contract.  All Items of Payment  received  by the Agent
pursuant  hereto  which are  finally  paid in cash or solvent  credits  shall be
applied  against the  Obligations  as provided in the  Security  Agreement.  Any
portion of the Items of Payment  which the Agent elects not to so apply shall be
paid over to the  Assignor  or to  whomsoever  shall be entitled  thereto  under
applicable  law,  including  pursuant  to  Section  9-504(1)(C)  of the  Uniform
Commercial Code of the Commonwealth of Virginia.

         6.  No  Waiver.   Neither  this  Agreement  nor  any  term,  condition,
representation,  warranty, covenant, or agreement hereof may be changed, waived,
discharged,  or terminated  orally,  but only by an instrument in writing by the
party against whom such change, waiver, discharge, or termination is sought.

         7. Governing law. THIS AGREEMENT  SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE  WITH THE LAWS OF THE  COMMONWEALTH  OF VIRGINIA,  WITHOUT  REGARD TO
PRINCIPLES OF CONFLICTS OF LAWS.

         8. Gender.  Whenever used herein, the singular number shall include the
plural,  the plural the singular,  and the use of the  masculine,  feminine,  or
neuter gender shall include all genders.

         9.  Counterparts.  This  Agreement  may be  executed  in any  number of
duplicate  originals,  each of  which  shall  be an  original  but all of  which
together shall constitute one and the same instrument.

         10. Paragraph  Headings.  The paragraph  headings of this Agreement are
for  convenience  only and  shall not limit or  define  the  provisions  of this
Agreement.

                  NOW,  THEREFORE,  in  consideration  of the premises and other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the Assignor covenants and agrees as follows:

         1. Incorporation By Reference. The provisions of the Security Agreement
are  incorporated  herein by  reference,  and the terms  defined in the Security
Agreement are used herein with the same meanings.

         2.  Representations.  The Assignor represents and warrants to the Agent
that (a) the Contract is legal,  valid and binding on the  Assignor  and, to its
knowledge,  the other parties thereto,  is in full force and effect,  and is not
evidenced  by any  chattel  paper or  instrument,  (b) upon due  filing  of this
Agreement,  together  with a Notice of Assignment  substantially  in the form of
Appendix A hereto with the authorized representative, the execution and delivery
of this Agreement does not violate and is not in conflict with the provisions of
the  Contract,  (c) there has been no default on the part of the Assignor or any
other party to the Contract, (d) the Assignor has made no previous assignment of
the  Contract to any person and knows of no fact or defense that will render the
moneys due or to be due  thereunder  uncollectible,  (e) no financing  statement
covering  the  Contract  is on  file  in  any  public  office  except  financing
statements in favor of the Agent,  (f) no set-off or  counterclaim to any moneys
due or to become  due  under the  Contract  exists  on the date  hereof,  and no
agreement  has been made with any person  under which any  deduction or discount
may be claimed,  and (g) the address of the office where the Assignor  keeps its
records concerning the Contract is ____________________.

         3. Collateral. As security and collateral for the payment of all of the
Obligations  (defined in the Security  Agreement)  and for  performance  of, and
compliance  with,  by the  Assignor,  all of the terms,  covenants,  conditions,
stipulations,  and  agreements  contained in this  Agreement and in the Security
Agreement,  the Assignor hereby assigns to the Agent,  and grants to the Agent a
lien on and  security  interest  in,  all  moneys  and claims for moneys now and
hereafter  due and to  become  due to the  Assignor  under or by  reason  of the
Contract,  together  with all  cash and  non-cash  proceeds  thereof;  provided,
however,  that nothing  contained  herein shall impose upon the Agent any of the
obligations or liabilities of the Assignor under the Contract.

         4. Covenants. Until payment and performance in full of the Obligations,
the Assignor covenants as follows:

(p) The  Assignor  shall  place  on any and all  vouchers,  invoices,  or  other
instruments demanding payment under the Contract the direction that such payment
is to be made to the Agent in accordance with Section 5 of this Agreement.

(q) The Assignor shall promptly upon request execute,  acknowledge,  and deliver
any  notice,  financing  statement,   renewal,   affidavit,   deed,  assignment,
continuation statement,  security agreement,  certificate,  or other document as
the  Agent  may  require  in  order to  perfect,  preserve,  maintain,  protect,
continue, and/or extend the assignment, lien, and security interest of the Agent
under this  Agreement and its priority.  The Assignor  shall pay to the Agent on
demand all taxes,  costs, and expenses  incurred by the Agent in connection with
the  preparation,  execution,  recording,  and  filing of any such  document  or
instrument  mentioned  aforesaid,  and such taxes,  costs,  and  expenses  shall
constitute  and become a part of the  Obligations.  A carbon,  photographic,  or
other  reproduction  of  a  security  agreement  or  a  financing  statement  is
sufficient as a financing statement.

(r) The Assignor shall fully,  promptly,  and faithfully comply with and perform
its  obligations  and duties  under the  Contract in  accordance  with the terms
thereof and will make no changes or  amendments  to the Contract or terminate or
cancel the  Contract  without the prior  written  consent of the Agent except as
permitted by the Security  Agreement.  In the event that any change,  amendment,
termination  or  cancellation  of  the  Contract  is  made  or  effected  by the
Government,  the Assignor  will  promptly  notify the Agent thereof and promptly
furnish to the Agent a copy of any  document or  agreement  evidencing  any such
change, amendment, termination, or cancellation.

(s)      The Assignor will promptly

          (i)  furnish to the Agent all  information  received  by the  Assignor
          affecting the moneys due and to become due under the Contract,

          (ii) inform the Agent of any delay in  performance  of, or claims made
          in regard to, the Contract, and

(iii) notify the Agent in writing of the failure of any party to the Contract to
perform any of its  obligations  thereunder and any rejection of any performance
rendered by the Assignor under or in connection with the Contract.

(t) The  Assignor  will at all times  keep  accurate  and  complete  records  of
performance  by the Assignor  under the  Contract,  and the Agent and its agents
shall have the right,  during normal business hours and upon reasonable  advance
notice,  to call at the place or places of business of the Assignor at intervals
to be  determined  by the Agent,  and without  hindrance  or delay,  to inspect,
audit,  check,  and make extracts  from the books,  records,  journals,  orders,
receipts,  correspondence,  and other data  relating  to the  Contract or to any
other transactions between the parties hereto related to the Contract.

         5. Payments. The Assignor hereby authorizes,  empowers, and directs the
Government to draw all checks,  drafts,  or other  instruments  representing the
payments of money due the Assignor under the Contract  (herein called the "Items
of Payment") to the order of  NationsBank,  N.A.,  assignee of Assignor,  and to
send  the  same  (i)  if by  mail,  to ,  (ii)  if by  electronic  transfer,  to
NationsBank, N.A. for the account of ________________, Bank Account #__________,
Agent ABA#_________,  or (iii) if by wire transfer, to NationsBank, N.A. for the
account of  _________________________,  Bank Account #_______,  ABA#___________.
If, despite this  direction,  any  instruments or checks  representing  payments
should be delivered to the Assignor,  the Assignor will immediately  endorse and
deliver such  instruments or checks to the order of the Agent. The Assignor does
hereby  irrevocably  (subject  to  revocation  with the  consent  of the  Agent)
designate and appoint (which appointment is coupled with an interest) the Agent,
and the Agent's  successors in interest by operation of law, the Assignor's true
and  lawful  attorney  with  power  irrevocable  for  the  Assignor  and  in the
Assignor's  name,  place,  and  stead,  but at the sole cost and  expense of the
Assignor,  to receive,  endorse,  and collect all Items of Payment,  and to ask,
demand,  receive,  receipt,  and give acquittances for any and all amounts which
may be payable  or which  become due and  payable  by the  Government  under the
Contract,  and in the Agent's  discretion to file any claim or to take any other
action  or  proceeding,  either  in the  Agent's  own name or in the name of the
Assignor or otherwise,  which to the Agent or any successor in interest  thereof
may seem  necessary  or  desirable in order to collect or endorse the payment of
any and all amounts now due or owing or which may  hereafter be or become due or
owing on account of the  Contract.  All Items of Payment  received  by the Agent
pursuant  hereto  which are  finally  paid in cash or solvent  credits  shall be
applied  against the  Obligations  as provided in the  Security  Agreement.  Any
portion of the Items of Payment  which the Agent elects not to so apply shall be
paid over to the  Assignor  or to  whomsoever  shall be entitled  thereto  under
applicable  law,  including  pursuant  to  Section  9-504(1)(C)  of the  Uniform
Commercial Code of the Commonwealth of Virginia.

         6.  No  Waiver.   Neither  this  Agreement  nor  any  term,  condition,
representation,  warranty, covenant, or agreement hereof may be changed, waived,
discharged,  or terminated  orally,  but only by an instrument in writing by the
party against whom such change, waiver, discharge, or termination is sought.

         7. Governing law. THIS AGREEMENT  SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE  WITH THE LAWS OF THE  COMMONWEALTH  OF VIRGINIA,  WITHOUT  REGARD TO
PRINCIPLES OF CONFLICTS OF LAWS.

         8. Gender.  Whenever used herein, the singular number shall include the
plural,  the plural the singular,  and the use of the  masculine,  feminine,  or
neuter gender shall include all genders.

         9.  Counterparts.  This  Agreement  may be  executed  in any  number of
duplicate  originals,  each of  which  shall  be an  original  but all of  which
together shall constitute one and the same instrument.

         10. Paragraph  Headings.  The paragraph  headings of this Agreement are
for  convenience  only and  shall not limit or  define  the  provisions  of this
Agreement.

                                                 PREMISES AND TERM

         2.1      Premises.

         Landlord  hereby  leases  to  Tenant,  and  Tenant  hereby  hires  from
Landlord,  for the Term,  subject to and with the benefit of the  provisions  of
this Lease,  Tenant's Space in the building (the "Building") located on the land
described in Exhibit A attached  hereto,  excluding  exterior  faces of exterior
walls,  the common  stairways,  stairwells,  elevators and elevator  wells,  and
pipes, ducts, conduits,  wire and appurtenant fixtures serving exclusively or in
common other parts of the Building, and if Tenant's Space includes less than the
entire  rentable  area of any floor,  excluding  the  central  core area of such
floor.  Tenant's Space, with said exclusions,  is hereinafter sometimes referred
to as the "Premises".

         2.2      Common Facilities.

         Tenant shall have, as appurtenant to the Premises,  the right to use in
common with others entitled thereto,  subject to rules of general  applicability
to tenants of the Building from time to time made by Landlord of which Tenant is
given notice:  (a) the common facilities in the Building or on the land on which
it is located (the  "Land"),  including  common  walkways,  driveways,  lobbies,
hallways,  ramps,  stairways,  elevators and loading  platforms;  (b) the common
pipes, ducts,  conduits,  wires and appurtenant  equipment serving the Premises;
and (c) if the Premises include less than the entire rentable area of any floor,
the common toilets and other common facilities.

         2.3      Landlord's Reservations.

Upon reasonable  prior notice (except in the event of emergency  constituting an
imminent threat to persons or property),  Landlord  reserves the right from time
to time,  without  unreasonable  interference  with Tenant's  Permitted Uses, to
install, repair, replace, use, maintain and relocate for service to the Premises
and  to  other  parts  of  the  Building,  pipes,  ducts,  conduits,  wires  and
appurtenant fixtures wherever located in the Building,  and to alter or relocate
any other common facility,  provided that the  substitutions  are  substantially
equivalent or better. Installations, replacements and relocations referred to in
this  Section  2.3 shall be located in the  central  core  area,  above  ceiling
surfaces,  below floor surfaces or within the perimeter walls of the Premises to
the extent  practicable,  and in all events shall not materially reduce rentable
area or floor to ceiling  height.  Except to the extent required by emergencies,
Landlord will use reasonable  efforts to perform all such work at such times and
in such  manner as will  minimize  any  disruption  of the  conduct of  Tenant's
business.

         2.4      Term.

         To have  and to hold the  Premises  for a  period  commencing  with the

         2.5      Additional Terms.

         Provided that Tenant is not then in default after any applicable  grace
periods (a) in the payment of the Annual Fixed Rent, or Additional  Rent, or (b)
of any other obligation of Tenant under this Lease,  pursuant to any outstanding
notice  thereof  referred  to in  Section 9. 1,  Tenant  shall have the right to
extend the Term  hereof for up to two (2)  successive  periods of five (5) years
each,  such  options to extend to be exercised by the giving of notice by Tenant
to Landlord at least  twelve (12)  months  prior to the  expiration  of the then
current  term.  Upon the  giving of each such  notice,  this  Lease and the Term
hereof shall be extended,  for an additional term of five (5) years, without the
necessity for the execution of any additional documents.  Time is of the essence
in the giving of such notice.  In no event shall the Term hereof be extended for
more than ten (10) years after the  expiration  of the Initial  Term,  nor shall
Tenant have the right to exercise  succeeding  extension  options  unless it has
duly and validly  exercised  the extension  option next  preceding the extension
option being currently exercised by Tenant. The Extension Term shall be upon all
the terms,  conditions and provisions of this Lease except that the Annual Fixed
Rent during each of the Extension  Terms shall be ninety-five  percent (95 %) of
the Fair  Rental  Value (as  agreed  between  the  parties or as  determined  by
appraisal  of the Premises for such  Extension  Term,  but in no event less than
$44.00 p.s.f.  for all floors,  which, if not agreed upon by Landlord and Tenant
within three (3) months of the date on which the applicable Extension Term is to
commence,  shall  be  determined  by  appraisal  as  provided  in  Section  2.7.
Notwithstanding  the foregoing,  Tenant may advance said three (3) months period
to a fifteen  (15) month  period upon  written  notice to Landlord  prior to the
commencement  of such fifteen (15) month period to the end that any rental to be
determined  by  appraisal  shall have been  determined  and made known to Tenant
prior to the  last  date on which  Tenant  is  required  to give  notice  of its
intention to exercise its next arising extension option. For purposes of Section
2.7,  the day  following  expiration  of the  Original  Term  or an  immediately
preceding Extension Term shall be deemed the relevant Available Date.

         2.6      Determination of Fair Rental Value.

         In the  event  the  Fair  Rental  Value  of  the  Premises  during  any
Additional  Term must be  determined  by appraisal,  the  determination  of Fair
Rental Value shall be made as provided in Exhibit C hereto.

additions to the Premises in accordance with plans and  specifications  therefor
first approved by Landlord.  Non-structural  changes within the Premises costing
$25,000.00 or less in any one instance and aggregating no more than  $200,000.00
during  the  entire  term  hereof  may be made by  Tenant  without  the need for
Landlord's  approval;  however,  in any such instance  Tenant shall give written
notice  thereof to Landlord  prior to  commencing  any such change and otherwise
shall be bound by the remaining  provisions hereof.  Tenant shall have the right
to make  structural  changes to the  Premises  with the  written  consent of the
Landlord  which shall ,not be  unreasonably  withheld or delayed.  No structural
change of any nature may be made, however, if the same affects the appearance of
the Building aesthetically; is visible from outside the Building; materially and
adversely  affects the  operation of the Building or the rights of other tenants
thereof;  adversely  affects any structural  member of the Building;  and unless
notice  of such  intended  change  together  with a  complete  set of plans  and
specifications  therefor  is  delivered  to the  Landlord at least 30 days prior
commencement of the installation of such change.  Tenant may make non-structural
changes in excess of the above amounts upon receiving  Landlord's  prior written
consent,  which consent shall not be unreasonably  withheld or delayed.  Without
limiting  Landlord's  rights  to  disapprove  any such  changes  and  additions,
Landlord need not approve such plans and  specifications if the proposed changes
and additions will require significant expense to readapt the Premises to normal
office use on lease  termination  (unless Tenant pays such increased  costs), or
will  increase the cost of  insurance or taxes on the Building or of  Landlord's
services  called for by Section 5.1 or will violate any other  provision of this
Lease.   All  fixtures  and  all   paneling,   partitions,   railings  and  like
installations,  installed  in the  Premises at any time,  either by Tenant or by
Landlord  o n  Tenant's  behalf,  shall,  subject  to  Tenant's  right  to  make
alterations,  become the  property  of  Landlord  and shall  remain  upon and be
surrendered  with the Premises,  unless  Landlord  grants its  permission to the
removal of same,  within  twenty (20) days after the  receipt of written  notice
from  Tenant  requesting  such  permission.  Nothing  in this  Section  shall be
construed to prevent Tenant's removal of trade fixtures, but upon removal of any
such trade fixtures from the Premises or upon removal of other  installations as
may be required by Landlord, Tenant shall immediately and at its expense, repair
and restore the Premises to the condition  existing  prior to  installation  and
repair any damage to the  Premises  or the  Building  due to such  removal.  All
property  permitted  or  required to be removed by Tenant at the end of the term
remaining in the Premises after Tenant's  removal shall be deemed  abandoned and
may, at the election of Landlord,  either be retained as Landlord's  property or
may be removed  from the  Premises  by  Landlord  at  Tenant's  expense.  All of
Tenant's  changes  and  additions  shall be  coordinated  with  any  work  being
performed  by  Landlord  and in such  manner  as to  maintain  harmonious  labor
relations  and not to damage the  Building or Land or  interfere  with  Building
operation,  and  shall be  performed  by  Landlord's  general  contractor  or by
contractors  or workmen first  approved by Landlord  which approval shall not be
unreasonably  withheld or delayed.  Except  with  respect to work by  Landlord's
general  contractor,  Tenant,  before  its work is  started,  shall:  secure all
licenses and permits necessary therefor;  deliver to Landlord a statement of the
names of all its  contractors and  subcontractors  and the estimated cost of all

delivered  to  Landlord   certificates  of  all  such  insurance  prior  to  the
commencement  of any work on the  Premises  and shall  provide  upon  Landlord's
request  certified  copies  of the  insurance  policies.  Tenant  agrees  to pay
promptly  when due the entire  cost of any work done on the  Premises  by, or on
behalf of Tenant,  and not to cause or permit  any liens for labor or  materials
performed or furnished in connection  therewith to attach to the  Premises,  the
Building or any interest of Landlord therein. Tenant agrees promptly upon notice
or  knowledge  thereof to  discharge  or bond over any such  liens  which may so
attach in  accordance  with  Section  6.1.13  hereof,  and  agrees to  indemnify
Landlord for, from and against any and all loss, cost or expense (including, but
not limited to, reasonable attorneys'. fees and costs) incurred by Landlord as a
result of Tenant's work. The payment by Landlord of Landlord's  Contribution (as
defined in Section 3.3 below) shall not be construed as a "cost or expense" from
which Tenant must indemnify Landlord pursuant to the preceding sentence.

         Each  contractor  and  subcontractor  must  agree in  their  respective
contracts  to  defend,   save,   indemnify  and  hold  harmless  Landlord,   its
subsidiaries,  officers,  agents and employees from any and all claims, demands,

policies shall contain a waiver of subrogation by endorsement or otherwise,  and

property  insurance  represents the sole recourse for loss or damage to property
and each will have waived rights to recover for property damage from each other.

Contribution  shall be made  available to Tenant on or after January 1, 1998 and

Improvements  have been  constructed in accordance  with Tenant's Plans and upon
the  reasonable  satisfaction  of  Landlord  that no  mechanics  or other  liens
relating to such Tenant Improvements will thereafter arise against the Land, the
Building or the Premises. At Landlord's election, payments under any Requisition
may be made jointly to Tenant and  Tenant's  general  contractor  in such manner
(such as joint payees on a check),  as to require  acknowledgment  of receipt of
the amount of such payment by both parties.

                                                    ARTICLE IV

                                                       RENT

         4.1      Fixed Rent.

         Tenant agrees to pay,  without any offset or deduction  whatever except
only,  to the  extent  applicable,  as  specifically  provided  pursuant  to the
provisions of Articles  III, V and VII hereof,  Annual Fixed Rent to Landlord at
the appropriate rate set forth in Section 1. 1 hereof, in equal  installments of
1/12th of the Annual  Fixed  Rent in  advance on the first day of each  calendar
month included in the Term, commencing on the Rent Commencement Date and for any
portion of a calendar  month at the  beginning or end of the Term,  at that rate
payable in advance for such portion.  Tenant shall pay all rent when due; and no
invoice  for rent due or to  become  due or  notice  of rent  past due  shall be
required.

         4.2      Additional Rent.

                  4.2.1    Taxes.

         Tenant shall pay to Landlord as additional rent a  proportionate  share
(as defined in Section  4.2.4) of all real  estate  taxes (as defined in Section
4.2.2)  imposed  against the  Building and the Land  attributable  to the period
commencing  twelve (12) months after the Term Commencement  Date,  prorated with
respect to any  portion of a fiscal year in which the first  anniversary  of the
Term of this  Lease  occurs or the Tenn  ends.  Such  payments  shall be due and
payable ten (10) days after notice is given to Tenant by Landlord,  which notice
is intended to be given during the period thirty (30) days just prior to the due
date of each half fiscal year's taxes.  If Landlord  shall receive any refund of
real estate taxes of which Tenant has paid a portion  pursuant to this  Section,
then, out of any balance remaining after deducting  Landlord's expenses incurred
in obtaining such refund,  Landlord  shall pay to Tenant the same  proportionate
share of said  balance,  prorated  as set forth  above.  Tenant  shall with each
monthly  installment  of Annual Fixed Rent,  make tax fund payments to Landlord.
The term "tax fund payments refers to such payments as Landlord shall reasonably
determine to be  sufficient  to provide in the aggregate a fund adequate to pay,
when they become due and payable,  all payments  required from Tenant under this
Section.  In the  event  that said tax fund  payments  are not  adequate  to pay
Tenant's  share of such taxes,  Tenant shall pay to Landlord the amount by which
such aggregate of tax fund payments is less than the amount of said share,  such
payment to be due and payable at the time set forth above.  Any surplus tax fund
payment to Landlord  shall be accounted  for to Tenant after payment by Landlord
of the taxes on  account  of which  they were  made,  and shall be  credited  by
Landlord  against future tax fund payments  except that if such surplus tax fund
payment exceeds $1,500.00,  it shall, on Tenant's demand, be refunded to Tenant.
If such surplus  fund  payment  exceeds the amount that should have been paid by
more than ten percent (10 %),  Landlord  shall pay to, or credit  Tenant (as the
case may be) with  interest on such surplus at an annual rate of interest  equal
to two  percent (2 %) greater  than the prime rate of  interest,  so-called,  of
BankBoston,  N.A.  in effect  at the time.  Subject  to the  provisions  of this
Section,  Landlord shall be responsible for payment of all real estate taxes (as
hereinabove  defined)  imposed against the Building and the Land. If the size of
the Building changes, the same shall be equitably reflected hereunder.

         4.2.2    Real Estate Taxes.

         The term "real estate  taxes" as used herein shall mean all real estate
taxes, assessments, and other governmental impositions and charges of every kind
and nature whatsoever not included in Operating Expenses,  extraordinary as well
as ordinary,  foreseen and unforeseen,  and each and every installment  thereof,
which shall or may during the Term as it may be extended be  assessed,  imposed,
become due and payable or be levied by the lawful taxing authorities against the
Land,   the  Building,   and  all  other   improvements   located  on  the  Land
(collectively,  the  "Property") or liens upon or arising in connection with the
use or occupancy or possession of, or becoming due or payable out of or for, the
Property or any part thereof,  including all costs and fees incurred by Landlord
in  contesting  same  or  in  negotiating  with  the  appropriate   governmental
authorities as to the same.  Betterments and other charges payable over a period
in excess of one year  shall  with the  interest  charges  thereon be treated as
being paid over the longest possible period.

         Except to the extent the same are generally considered to be in lieu of
real estate taxes,  nothing herein  contained shall be construed to include as a
real estate tax any inheritance,  estate, succession, transfer, gift, franchise,
corporation, income or profit tax or capital levy that is or may be imposed upon
Landlord;  provided,  however, that, if at any time during the Term as it may be
extended the methods of taxation  prevailing at the Term Commencement Date shall
be  altered so that in lieu of or as a  substitute  for the whole or any part of
the taxes now levied,  assessed or imposed,  there shall be levied,  assessed or
imposed  an income  or other  tax of  whatever  nature,  then the same  shall be
included in the computation of real estate taxes hereunder.

         Real estate  taxes shall  include  any  excise,  transaction,  sales or
privilege tax now or hereafter imposed by any government or governmental  agency
upon Landlord on account of, attributed to, or measured by rent or other charges

on the  Property,  and shall be repaid by Tenant to  Landlord in addition to and
together with the Rent and other charges otherwise payable hereunder;  provided,
that any tax levied by reason of the parking shall be apportioned so that Tenant
shall  reimburse  Landlord for that portion of such parking tax in proportion to
the  number of parking  spaces  provided  to Tenant  under  subparagraph  10. 18
hereof.


         4.2.3 Operating Expenses.

         Tenant shall pay to Landlord as additional rent a  proportionate  share

from  and  after  the  period  commencing  twelve  (12)  months  after  the Tenn
Commencement  Date in the operation and maintenance of the Building and the Land

(h) the cost of repair of damage caused by third
parties if reimbursement is received

such cost shall not be included in this
subsection h, of this Lease;

(i)  expenses related to parking  operations  associated with the Building other
     than after hours security;

(j) the cost of installing, operating and
maintaining any specialty service, such as

newsstand, concession, or athletic or
recreational club;

(k) the cost of correcting defects in base building construction (i.e. excluding
normal maintenance and repair expenses);

(r) Expenditures for capital items other than an

incurred for such period absent the
installation of any such capital item.

         Operating  expenses  shall  be  reduced  by  the  amount  of  insurance
proceeds,  reimbursements,  discounts  or  allowances  received  by  Landlord in
connection with such costs.

As soon as Tenant's  share of  operating  expenses  with respect to any calendar
year can be determined,  a statement of Tenant's share will be sent to Tenant at
which time said amount shall become payable to Landlord  within thirty (30) days
following the date of said  statement,  subject to proration with respect to any
portion  of a  calendar  year in which  the Term of this  Lease  begins or ends.
Landlord's  records of operating  expenses  with respect to each  calendar  year
shall be  available  for  inspection  by  Tenant  for six (6)  months  following
delivery by Landlord of its  statements  of  operating,  expenses for such year.
Tenant  may,  at  reasonable  time and after  notice to  Landlord,  inspect  all
invoices  and other  supporting  material  relevant to the  computation  of said
operating  expenses.  Tenant shall with each monthly installment of Annual Fixed
Rent,  make  operating  fund  payments to  Landlord.  The term  "operating  fund
payments" shall refer to such payments as Landlord shall reasonably determine to
be  sufficient  to provide in the  aggregate a fund  adequate to pay,  when they
become due and payable, all payments required from Tenant under this Section. In
calculating  operating  fund  payments,  Landlord  shall take into  account  the
operating  expenses  incurred  in the  previous  year.  In the  event  that  the
aggregate of said  operating fund payments is not adequate to pay Tenant's share
of  operating  expenses,  Tenant  shall pay to Landlord the amount by which such
aggregate  is less than the  amount of said  share,  such  payment to be due and
payable at the time set forth above.  Any surplus  operating fund payments shall
be accounted for to Tenant after such surplus has been determined,  and shall be
credited by Landlord  against future operating fund payments except that if such
surplus operating fund payment exceeds $1,500.00, it shall on Tenant's demand be
refunded to Tenant.  If such surplus fund payment exceeds the amount that should
have been paid by more than ten percent (10%),  Landlord shall pay to, or credit
Tenant (as the case may be) with  interest on such  surplus at an annual rate of
interest  equal to two percent  (2%)  greater  than the prime rate of  interest,
so-called,  of the  BankBoston,  N.A.,  in effect at the time. In the event of a
dispute between  Landlord and Tenant as to the propriety in the amount or nature
of any operating expense Landlord has requested Tenant to. pay, Tenant shall pay
the same at the time called for  hereunder as if the same were properly due, but
upon  notice  from  Tenant  to  Landlord,  the  matter  shall  be  submitted  to
arbitration in a manner reasonably  consistent with the provisions of Exhibit C,
hereto.

         4.2.4 Tenant's Proportionate Share.

         Tenant's proportionate share of taxes payable pursuant to Section 4.2.1
shall be the excess of real estate taxes allocable to the Premises over Tenant's
Included  Share of Real Estate Taxes,  where real estate taxes  allocable to the
Premises means the real estate taxes for the Property  multiplied by a fraction,
the  numerator  of  which is the  number  of  p.s.f.  of the  Premises,  and the
denominator of which is the number of p.s.f. in the Total Rentable Floor Area of
the  Building.  Tenant's  proportionate  share  of  operating  expenses  payable
pursuant to Section 4.2.3 shall be the excess of operating expenses allocable to
the Premises over Tenant's Included Share of Operating Expenses, where operating
expenses allocable to the Premises means the operating expenses for the Property
multiplied by a fraction,  the numerator of which is the number of p.s.f. of the
Premises  and the  denominator  of which is the  number of  p.s.f.  in the Total
Rentable Floor Area of the Building.

         Reference  is hereby  made to that  portion  of Article I of this Lease
which defines Tenant's Included Share of Real Estate Taxes and Tenant's Included
Share of Operating  Expenses for the purposes of the calculations  called for in
this Paragraph 4.2.4:

                                    (a) For the  period  commencing  January  1,
                  1998 and continuing  through  November 30, 1999, to the extent
                  that the operating  expenses  allocable to the Premises amount
                  to less than $4.50 per p.s.f.,  the amount of such  difference
                  shall be added to the $3.00  per  p.s.f.  figure  of  Tenant's
                  Included   Share  of  Real  Estate  Taxes.   Thus  by  way  of
                  hypothetical  example, if during any period within the Term of
                  this Lease the  operating  expenses  allocable to the Premises
                  are $4.15 per p.s.f., then during the period during which said
                  $4.15 per p.s.f. figure is applicable, Tenant's Included Share
                  of Real Estate  Taxes shall be treated as if it were $3.35 per
                  p.s.f.; and


                                    (b) For the period  commencing  December  1,
                  1999 and continuing  through  November 30, 2009, to the extent
                  that the operating  expenses  allocable to the Premises amount
                  to less than $5.60 per p.s.f.,  the amount of such  difference
                  shall be added to the $5.50  per  p.s.f.  figure  of  Tenant's
                  Included   Share  of  Real  Estate  Taxes.   Thus  by  way  of
                  hypothetical  example, if during any period within the Term of
                  this Lease the  operating  expenses  allocable to the Premises
                  are $5.00 per p.s.f., then during the period during which said
                  $5.00 per p.s.f. figure is applicable, Tenant's Included Share
                  of Real Estate  Taxes shall be treated as if it were $6.10 per
                  p.s.f.; and


                                    (c) For the  period  commencing  January  1,
                  1998 and continuing  through  November 30, 1999, to the extent
                  that the real estate taxes allocable to the Premises amount to
                  less than  $3.00 per  p.s.f.,  the  amount of such  difference
                  shall be added to the $4.50  per  p.s.f.  figure  of  Tenant's
                  Included  Share  of  Operating   Expenses.   Thus  by  way  of
                  hypothetical  example,  if the real estate taxes  allocable to
                  the  Premises  are $2.70 per  p.s.f.,  then  during the period
                  during  which  said  $2.70 per  p.s.f.  figure is  applicable,
                  Tenant's Included Share of Operating Expenses shall be treated
                  as if it were $4.80 per p.s.f., and


                                    (d) For the period  commencing  December  1,
                  1999 and continuing  through  November 30, 2009, to the extent
                  that the real estate taxes allocable to the Premises amount to
                  less than  $5.50 per  p.s.f.,  the  amount of such  difference
                  shall be added to the $5.60  per  p.s.f.  figure  of  Tenant's
                  Included  Share  of  Operating   Expenses.   Thus  by  way  of
                  hypothetical  example,  if the real estate taxes  allocable to
                  the  Premises  are $5.25 per  p.s.f.,  then  during the period
                  during  which  said  $5.25 per  p.s.f.  figure is  applicable,
                  Tenant's Included Share of Operating Expenses shall be treated
                  as if it were $5.85 per p.s.f.


         Notwithstanding the forgoing,  at no time during the term of this Lease
shall Tenant's  Included Share of Real Estate Taxes and Tenant's  Included Share
of Operating Expenses, taken together,  exceed the aggregate figure of $7.50 per
p.s.f. of the Premises for the period commencing  January 1, 1998 and continuing
through  November 30, 1999,  and $11. 10 for the period  commencing  December 1,
1999 and continuing through November 30, 2009.

         4.2.5 Tenant's Electricity Usage.

         Tenant  shall  utilize  metered  electricity  directly  from the public
utility  providing such to Tenant's Space ("Tenant's  Electricity") for Tenant's
use for all  purposes  for which  Tenant uses  electricity  including  lighting,
electrical  outlets  and  "HVAC",  so-called.  Landlord  shall allow its vaults,
wires,  risers and conduits to be used by Tenant,  acting  reasonably,  for such
purposes.  Such  facilities  shall be stubbed to a central  service area on each
floor. Tenant shall pay the cost of the same directly to such utility.  Landlord
shall furnish  electricity  for use in common areas,  Tenant's use of which,  if
consumed  during other than normal Building Hours (as defined in Exhibit G), and
to the extent of what  otherwise  would have been  supplied  (and then only upon
request  of Tenant may be  separately  charged  to  Tenant,  provided  that such
charges  shall be fairly  allocated  among all tenants  using such  electricity.
Tenant shall not,  without  Landlord's  prior consent in each instance,  connect
anything  to  the  Building's  electric  system  which  would  constitute  a use
inconsistent with the electrical system servicing the Premises.  Should Landlord
grant such consent,  all additional risers or other equipment  therefor shall be
provided by Landlord at the Tenant's  expense.  Landlord shall make arrangements
regarding  replacement of lighting tubes, lamps, bulbs and ballasts for Tenant's
Space at  Tenant's  expense,  -but to be billed to  Tenant at  Landlord's  cost,
reasonably calculated.

                                               LANDLORD'S COVENANTS

         5.1      Landlord's Covenants.

         Landlord covenants:

                                    5.  1.  1  to  furnish,  through  Landlord's
                  employees or independent  contractors,  the services listed in
                  Exhibit  G,  all  of  the  same  to  be  equivalent  to  those
                  customarily  supplied to first class  office  buildings in the
                  Boston and Cambridge areas.


                                    5.1.2  except  as  otherwise  provided  with
                  respect to Landlord's  Building  restoration  obligations  set
                  forth in  Article  VII,  to make  such  repairs  to the  roof,
                  structural elements,

foundation,  insulation, caulking, exterior walls and glass, floor slabs and all
parts  of  the  common  areas  and  facilities  of  the  Building,  Garage,  and
landscaping  as may be  necessary  to keep  them  in  condition  suitable  for a
first-class office building.

                  5.1.3 that  Landlord has the right to make this Lease and that
Tenant,  on paying the rent and performing its obligations in this Lease,  shall
peacefully  and quietly have,  hold and enjoy the Premises  throughout the Term,
subject to all terms and provisions hereof.

                  5.1.4  to keep the  Property  free of liens  for  unpaid  real
estate  taxes and to the extent  required by the terms of this Lease to maintain
insurance on the common areas.

         5.2      Interruptions.

         Landlord  shall  not be  liable  to  Tenant  for  any  compensation  or
reduction  of rent by  reason  of  inconvenience  or  annoyance  or for  loss of
business  arising  from  power and  other  utility  losses  and  shortages,  the
necessity  of  Landlord's  entering the Premises for any of the purposes in this
Lease  authorized,  or for repairing the Premises or any portion of the Property
however the necessity  may occur.  In case Landlord is prevented or delayed from
making any repairs,  alterations or improvements,  or furnishing any services or
performing  any other  covenant or duty to be performed on  Landlord's  part, by
reason of any cause reasonably beyond Landlord's control,  Landlord shall not be
liable to Tenant  therefor,  nor,  except as  expressly  otherwise  provided  in
Section 7. 1, shall Tenant be entitled to any  abatement or reduction of rent by
reason  thereof,  nor shall the same give rise to a claim in Tenant's favor that
such failure constitutes actual or constructive, total or partial, eviction from
the Premises.

         Upon  reasonable  prior  notice  (except  in  the  event  of  emergency
constituting an imminent threat to persons or property),  Landlord  reserves the
right to stop any  service  or  utility  system,  when  necessary  by  reason of
accident or emergency, or until necessary repairs have been completed, provided,
however,  that in each  instance  of stoppage or  interruption,  Landlord  shall
exercise reasonable diligence to minimize any inconvenience to Tenant.

         The foregoing provisions hereof to the contrary notwithstanding, in the
event any power or other utility  failure or service  failure (other than office
cleaning) which is an obligation of Landlord under this Lease (including failure
of elevator service and failure to repair any structural element of the Building
which Landlord is obligated to repair hereunder)  results in Tenant's  inability
to conduct its business on the  Premises  substantially  as permitted  hereunder
(herein,  a "Shutdown"),  and in the event such Shutdown continues for more than
fifteen business days or for more than five  consecutive  business days (in each
case) in any calendar year, then the Annual Fixed Rent hereunder shall be abated
for each  additional  business  day in such  calendar  year  during  which  such
Shutdown  continues.  Further,  if a Shutdown  continues for twelve  consecutive
months,  Tenant  shall have the right  thereafter,  by written  notice  given to
Landlord while such Shutdown continues, to terminate this Lease.

                  equipment) regardless to whomever assessed,  and to the extent

                  to  invalidate,  or (unless Tenant pays the same, or if caused
                  by more than one party, its equitable share thereof)  increase

                  others;  not without prior consent of Landlord  (which consent
                  shall not be  unreasonably  withheld or delayed) to permit the
                  painting  or  placing  of  any  signs  or the  placing  of any
                  curtains,  blinds, shades,  awnings,  aerials or flagpoles, or
                  the like,  visible  from outside the  Premises;  and to comply
                  with the Rules and  Regulations set forth in Exhibit H and all
                  other    reasonable   Rules   and   Regulations   of   general
                  applicability to all tenants in the Building hereafter made by
                  Landlord which Landlord shall use reasonable  efforts to apply
                  in a nondiscriminatory  manner, of which Tenant has been given
                  notice. Landlord shall not be liable to Tenant for the failure
                  of other  tenants of the Building to conform to such Rules and
                  Regulations.  In the event of any inconsistency between any of
                  said Rules and  Regulations  and the terms of this Lease,  the
                  terms of this Lease shall prevail;


         6.1.5 to keep the Premises equipped with all safety appliances required
by law or ordinance or any other regulation of any public  authority  because of
any use made by  Tenant  other  than the  Permitted  Uses,  and to  procure  all
licenses  and  permits so  required  because of such use and,  if  requested  by
Landlord,  to do any work so required  because of such use, it being  understood
that the  foregoing  provisions  shall not be  construed  to  broaden in any way
Tenant's Permitted Uses;

         6.1.6

                                    (a) That in the  event  Tenant  proposes  to
                  assign this Lease or sublet the Premises or any part  thereof,
                  Tenant shall give Landlord  written  notice thereof sixty (60)
                  days prior  thereto  which  notice  shall  specify the date on
                  which such  assignment  or subletting is to occur or commence.
                  Landlord  shall  then  have  a  period  of  thirty  (30)  days
                  following receipt of such notice within which to notify Tenant
                  in writing that Landlord elects (1) to terminate this Lease as
                  to the space so affected as of the date so specified by Tenant
                  but only for the term so  specified in which event Tenant will
                  be relieved of all further  obligations  hereunder  as to such
                  space on that date for the term so specified, or (2) to permit
                  Tenant  subject to all the remaining  terms and  provisions of
                  this  Lease  to  assign  this  Lease  or  sublet  such  space,
                  provided,  however, that in the case of such later election by
                  Landlord,  such  subletting or  assignment  shall be permitted
                  only to a party  with a  general  reputation  in the  business
                  community  comparable  to that  of  Tenant  and of  comparable
                  creditworthiness (but, with respect to any subletting,  taking
                  into account the amount of space sublet and the term thereof).
                  If  Landlord  shall  fail to notify  Tenant in writing of such
                  election within said thirty (30) day period, Landlord shall be
                  deemed to have elected option (2) above. If Landlord elects to
                  exercise  option  (2) above,  Tenant  agrees to provide at its
                  expense,  reasonable,  proper and legal direct access from the
                  assignment  or  subleased  space to a public  corridor  of the
                  Building.


                                    (b) If Landlord  consents to any  subletting
                  or  assignment  by  Tenant  as   hereinabove   provided,   and
                  subsequently  any  rents  received  by  Tenant  under any such
                  sublease  are in excess of the rent  payable  by Tenant  under
                  this lease, or any additional  consideration is paid to Tenant
                  by the assignee under any such assignment,  then fifty percent
                  (50%) of the  excess  rents  (after  deduction  for actual and
                  reasonable  "out of  pocket"  cash  expenses)  under  any such
                  sublease  or  the  additional   consideration   for  any  such
                  assignment  shall be due and  payable by Tenant to Landlord as
                  additional  rent  hereunder  when  received by Tenant,  Tenant
                  agreeing to use reasonable efforts to collect the same.


                                    (c) Notwithstanding anything to the contrary
                  contained  herein,  Tenant  shall have the  absolute  right to
                  assign  its  interest  in this  Lease or sublet  the  Premises
                  without  Landlord's  consent (and in such cases the  foregoing
                  subparagraphs  (a) and (b) shall not apply) in connection with
                  any assignment or sublease to any parent, subsidiary, or other
                  entity controlled by or under common control with Tenant;  any
                  assignment or sublease  occurring by operation of law; and any
                  assignment or sublease  occurring in connection with a sale of
                  all or  substantially  all of the  assets or capital or common
                  stock of Tenant or a consolidation or merger of Tenant.


                                    (d) No assignment  shall be deemed permitted
                  hereunder   unless   Tenant  shall   deliver  to  Landlord  an
                  instrument  in  recordable  form which  contains a covenant of
                  assumption by the assignee running to Landlord and all persons
                  claiming  by through  or under  Landlord,  but the  failure or
                  refusal  of  such  assignee  to  execute  such  instrument  of
                  assumption  shall not release or discharge  such assignee from
                  its liability hereunder nor shall execution of such instrument
                  of  assumption  affect the  continuing  primary  liability  of
                  Tenant.


                                    (e)  No  subletting  or  assignment  of  any
                  nature by Tenant shall relieve Tenant of any obligations under
                  this I-ease.


                                    (f)  Tenant  shall  have no right to  assign
                  this Lease or sublet all, or any portion of the Premises while
                  any  default  exists  hereunder  beyond any  applicable  grace
                  period.


                                    (g) No  assignment or sublease of any nature
                  may be made to any party who then is a tenant or  occupant  of
                  the Building unless Landlord, itself, is unable to satisfy the
                  need of such proposed assignee or sublessee.


         In the event of any  subletting  under this Lease pursuant to the terms
hereof,  upon the  request  of  Tenant,  Landlord  will  provide  the  subtenant
thereunder (the "Subtenant")  with an agreement binding upon Landlord  providing
that in the event of  termination  of the Lease by virtue of  Tenant's  default,
Landlord  will continue to recognize and accept the Subtenant as a tenant in the
sublet premises for the term of the Subtenant's  (sub) tenancy  provided (a) the
terms of such  subtenancy  are  identical to the  provisions of the Lease (or at
least no less favorable to Landlord)  other than (i) the rental,  tax escalation
and  operation  expense  payments  and the parking  space  allocation  under the
sublease may be reduced in proportion to the amount of floor space so subleased;
(H) the  Subtenant  shall have no rights to extend the term of the sublease past
the original term of the Lease or have any rights to expand its premises or take
advantage  of any  options  or  first  refusal  on  any  space  in the  Building
(including the space leased under the Lease but not demised under the sublease);
(iii) the term of such sublease shall not commence until after the  Commencement
date under the Lease  with the result  that  Tenant  shall have no  construction
obligations to the Subtenant under paragraph 3.1 of the lease; and (b) the floor
space covered by such  sublease  shall cover the entire amount (and no less than
the  entire  amount)  of one or more  "Sublease  Sections"  of the  Premises  as
referred to on Exhibit I hereto;

         6.1.7  To the  maximum  extent  this  agreement  may be made  effective
according,  damages,  losses, injuries or claims of whatever nature arising from
any act, omission or negligence of Tenant, or Tenant's  contractors,  licensees,
invitees, agents, servants or employees, or arising from any accident, injury or
damage  whatsoever  caused to any person or property,  occurring  after the date
that  possession of the Premises is first  delivered to Tenant and until the end
of the Term and  thereafter,  in or  about  the  Premises  or  arising  from any
accident,  injury or damage  occurring  outside  the  Premises  but  within  the
Building,  on the  Land or  with  respect  to the  parking  facilities  provided
pursuant to the Lease,  in each of the foregoing  instances where such accident,
injury  or  damage  results,  or is  claimed  to have  resulted,  from an act or
omission  on the part of Tenant or  Tenant's  agents  or  employees,  licensees,
invitees,  servants or contractors.  This indemnity and hold harmless  agreement
shall include indemnity against all costs,  expenses and liabilities incurred or
in connection with any such claim or proceeding brought thereon, and the defense
thereof.

         Tenant agrees to maintain in full force from the date upon which Tenant
first enters the Premises for any reason,  throughout the Term, and  thereafter,
so long as  Tenant  is in  occupancy  of any part of the  Premises,  a policy of
liability  insurance  more  particularly  described  below in this Section 6.1.7
under  which  Landlord  (and any ground  lessor and holder of a mortgage  on the
Property of whom Tenant has  knowledge)  and Tenant are named as  insureds,  and
under which the insurer provides a contractual  liability  endorsement  insuring
against all cost, expense and liability arising out of or based upon any and all
claims,  accidents,  injuries  and  damages  described  in  Section 7. 1, in the
broadest form of such coverage,  from time to time  available.  Each such policy
shall be  non-cancelable  and  non-amendable  (to the extent  that any  proposed
amendment  reduces  the limits or the scope of the  insurance  required  in this
Lease) with respect to Landlord and such ground lessors and  mortgagees  without
thirty (30) days' prior written  notice to Landlord and such ground  lessors and
mortgagees  and a duplicate  original  thereof  shall be  delivered to Landlord.
Without limitation of the foregoing,  the scope of such insurance shall include,
and the minimum  limits of liability of such  insurance  for each year shall be:
commercial general liability insurance, including broad form property damage and
contractual liability: general aggregate $2,000,000, each occurrence $1,000,000,
personal & advertising injury $1,000,000 and medical payments $5,000 per person;
employer's liability insurance covering bodily injury by disease with such limit
not less than  $1,000,000 for each person and a 1,000,000  policy limit;  bodily
injury  by  accident   with  limits  of  not  less  than   $1,000,000;   and  an
umbrella/excess  liability  policy  with  minimum  limits of  $5,000,000  in the
aggregate  and  $5,000,000  per  occurrence.  All  policies  shall be written by
companies rated not less than A - VIII by Best's Insurance Reports. Landlord may
from time to time during the Term hereof,  require higher limits, if such higher
limits are carried  customarily  in the  Boston-Cambridge  area with  respect to
similar  premises in similar  properties,  provided such  provision is uniformly
enforced within the Building;

                                    6.1.8 To keep all Tenant's employees working
                  in the Premises covered by workmen's compensation insurance in
                  statutory  amounts and to furnish  Landlord with  certificates
                  thereof;


                  6.1.9 Upon reasonable  prior notice other than in the event of
emergency  constituting  a threat to life or  property  to permit  Landlord  and
Landlord's  agents to examine the Premises and, if Landlord  shall so elect,  to
make  any  repairs  or  replacements  Landlord  may deem  necessary  to avert an
emergency,  to remove,  at Tenant's  expense,  any  changes,  additions,  signs,
curtains,  blinds,  shades,  awnings,  aerials,  flagpoles,  or  the  like,  not
consented to in writing (if such consent is required hereunder), and to show the
Premises to  prospective  tenants during the last twelve (12) months of the Term
or at any time after any notice of termination of this Lease, and to prospective
purchasers and prospective mortgagees at any time during the term of this Lease;


                  6.1.10  Not to place a load  upon the  Premises  exceeding  an
average rate of 50 pounds of live load per square foot of floor area; and not to
move any safe,  vault or other heavy  equipment in, about or out of the Premises
except in such  manner  and at such  times as  Landlord  shall in each  instance
authorize;  Tenant's  business  machines and  mechanical  equipment  which cause
vibration or noise that may be transmitted  to the Building  structure or to any
other leased space in the Building  shall be placed and  maintained by Tenant in
settings  of cork,  rubber,  spring,  or  other  type of  vibration  eliminators
sufficient to eliminate such vibration or noise;


                                    6.1.11   All  the   furnishings,   fixtures,
                  equipment,  effects and  property  of every  kind,  nature and
                  description of Tenant and of all persons  claiming by, through
                  or under Tenant which, during the continuance of this Lease or
                  any  occupancy  of the  Premises by Tenant or anyone  claiming
                  under  Tenant,  may be on the  Premises  or  elsewhere  in the
                  Building,  shall be at the sole risk and hazard of Tenant, and
                  if the whole or any part thereof shall be destroyed or damaged
                  by fire, water or otherwise,  or by the leakage or bursting of
                  water pipes, steam pipes, or other pipes, by theft or from any
                  other  cause,  no part of said loss or damage is to be charged
                  to or to be borne by Landlord  unless caused by the negligence
                  or willful misconduct of Landlord or its agents or employees;


                                    6.1.12  Not to suffer or permit any liens to
                  stand  against  the  Premises  by reason of work  done,  labor
                  services performed or materials provided for or at the request
                  of Tenant.  Tenant shall cause any such liens to be discharged
                  within  thirty (30) days after the date of notice to Tenant or
                  Tenant's  knowledge of the filing thereof,  but nothing herein
                  shall prevent Tenant from  contesting any such lien,  provided
                  that  Tenant  shall  first  provide  a  surety  bond or  other
                  security therefor satisfactory to Landlord;


                                    6.1.13 In case  Landlord  or  Tenant  shall,
                  without any fault on its part, be made party to any litigation
                  commenced by or against the other or by or against any parties
                  in possession  of the Premises or any party  thereof  claiming
                  under  the  other,  to  pay,  all  costs,   including  without
                  limitation,  reasonable  counsel  fees  incurred by or imposed
                  upon the other in connection with such litigation; and also to
                  pay  all  such  costs  and  fees  incurred  by  the  other  in
                  connection with the successful enforcement by the other of any
                  obligations  of the other under this Lease.  Any such payments
                  due from  Tenant  shall be deemed  Additional  Rent under this
                  Lease; and


                                    6.1.14 Upon the  expiration of this Lease or
                  should this Lease terminate for any cause,  and at the time of
                  such expiration or termination, the Tenant or Tenant's agents,
                  subtenants  or any other  person  should leave any property of
                  any kind or character on or in the premises,  the fact of such
                  leaving  of  property  on or in the Leased  Premises  shall be
                  conclusive  evidence of intent by the Tenant,  Tenant's agents
                  or subtenants, to abandon such property so left in or upon the
                  Premises, and such leaving shall constitute abandonment of the
                  property.


         Landlord,  its agents or attorneys,  shall have the right and authority
without  notice to Tenant,  Tenant's  agent or  subtenants,  or anyone else,  to
remove and destroy,  or to sell or authorize  disposal of such property,  or any
part  thereof,  without being in any way liable to the Tenant or any other party
therefore.  The  proceeds  received  therefor  shall  belong to the  Landlord as
compensation for the removal and disposition of said property.


         It is understood and agreed by and between the parties hereto that none
of Landlord's  servants,  agents or employees,  have or shall have the actual or
apparent authority to waive any portion of this paragraph,  and the Tenant shall
have no right to leave any such property  upon the Premises  without the written
consent of Landlord.


                                                    ARTICLE VII

                                                CASUALTY AND TAKING

         .7.1     Casualty and Taking.

                                    (a) If,  during the Term,  the  Building  or
                  Premises  shall be partially  damaged (as  distinguished  from
                  "substantially  damaged," as that term is hereinafter defined)
                  by  fire or  casualty,  Landlord  shall  proceed  promptly  to
                  restore the Building or Premises  (consistent,  however,  with
                  governmental   laws   and   codes   then  in   existence)   to
                  substantially  the  condition  thereof  at the  time  of  such
                  damage,  but Landlord  shall not be  responsible  for delay in
                  such  restoration  which may result from any cause  beyond the
                  reasonable control of Landlord.


                                    (b) If  during  the  Term  the  Building  or
                  Premises  shall be  substantially  damaged  (as  that  term is
                  hereinafter defined) by fire or casualty, the risk of which is
                  covered  by  Landlord's   insurance  and  the  holder  of  any
                  outstanding  mortgage  which  includes the Building as part of
                  the mortgaged  premises  (whose actions  shall,  to the extent
                  Landlord  acting  reasonably  can effect the same,  be in good
                  faith)  allows  the  insurance  proceeds  to be applied to the
                  restoration of the Building,  Landlord  shall,  promptly after
                  such  damage  and  the  determination  of the  net  amount  of
                  insurance  proceeds  available to Landlord,  expend so much as
                  may be  necessary  of such net amount to restore  (consistent,
                  however,  with  governmental laws and codes then in existence)
                  the  Building  and  Premises to  substantially  the  condition
                  thereof at the time of such damage,  but Landlord shall not be
                  responsible  for delay in such  restoration  which may  result
                  from any cause beyond the reasonable  control of Landlord.  If
                  the Building or the Premises shall be substantially damaged by
                  fire or  casualty  (a) as the result of a risk not  covered by
                  the forms of  casualty  insurance  at the time  maintained  by
                  Landlord, or (b) such holder of an outstanding mortgage (whose
                  actions shall, to the extent  Landlord  acting  reasonably can
                  effect  the  same,  be in  good  faith)  will  not  allow  the
                  insurance  proceeds  to be applied to the  restoration  of the
                  Building,   or  (e)  the  net  amount  of  insurance  proceeds
                  available  to Landlord are  insufficient  to cover the cost of
                  restoring the Building in the reasonable estimate of Landlord,
                  then  in any  such  case,  Landlord  may,  but  shall  have no
                  obligation to, restore (consistent, however, with governmental
                  laws  and  codes  then  in  existence)  the  Building  and the
                  Premises to substantially the condition thereof at the time of
                  such damage or  Landlord  may  terminate  this Lease by giving
                  notice  to  Tenant  within  forty-five  (45)  days  after  the
                  occurrence of such fire or casualty, which notice shall recite
                  the reason  among those set forth above for such  termination.
                  Landlord  shall  not  exercise  such  right  of   termination,
                  however,  unless, Landlord terminates all other leases then in
                  effect  in the  Building,  which  Landlord  has the  right  to
                  terminate by virtue of such casualty.

                                    (c) If  Landlord  shall  notify  Tenant that
                  Landlord  does not intend to restore the Building and Premises
                  by reason of the  unavailability or insufficiency of insurance
                  proceeds,  Tenant  shall  have  the  right  to  contribute  to
                  Landlord the amount of such insufficiency, and if Tenant shall
                  promptly notify Landlord of Tenant's desire to contribute such
                  insufficiency  and provide Landlord with security for Tenant's
                  undertaking in this respect satisfactory to Landlord, Landlord
                  shall promptly  commence and thereafter  diligently  pursue to
                  completion the restoration of the Building and Premises unless
                  otherwise excused by some other provision of this Article VII.


                                    (d) If Landlord  does not within  forty-five
                  (45) days after such fire or  casualty,  advise  Tenant of the
                  status   of   Landlord's    obligations    with   respect   to
                  reconstruction,  i.e.,  whether  the net  amount  of  proceeds
                  available to cover the cost of restoration  are sufficient for
                  restoration  which is expected to be completed  within six (6)
                  months; or that Landlord  reasonably expects to restore within
                  six (6) months  regardless of the  sufficiency or availability
                  of proceeds;  or that Landlord  intends to  terminate,  Tenant
                  itself  shall  have  the  right  until  Landlord   intends  to
                  terminate,  Tenant itself shall have the right until  Landlord
                  shall  have  notified  Tenant  of  Landlord's  intentions,  to
                  terminate  this Lease,  such  termination to take effect as of
                  the date of such Tenant's notice.


                                    (e) If the Premises  shall be  substantially
                  damaged  by fire or  casualty  within the last  eighteen  (18)
                  months of the Term (as the same may theretofore  have been, as
                  may  thereafter  be (by written  notice  given within ten (10)
                  days of any such  notice  by  Landlord)  extended  hereunder),
                  either  party  shall have the right,  by giving  notice to the
                  other not later than sixty  (60) days  after such  damage,  to
                  terminate this Lease,  whereupon this Lease shall terminate as
                  of the date of such notice.


                                    (f) The term "substantially  damaged as used
                  in this Article VII, shall refer to damage of such a character
                  that  the same  cannot,  in  ordinary  course,  reasonably  be
                  expected to be repaired  within ninety (90) days from the time
                  that repair work would commence.


                                    (g) Except as hereinafter  provided,  if the
                  Premises, or such portion thereof as to render the balance (if
                  reconstructed  to  the  maximum  extent   practicable  in  the
                  circumstances)  unsuitable  for  Tenant's  purposes,  shall be
                  taken by condemnation or right of eminent domain, Tenant shall
                  have the right to  terminate  this Lease by notice to Landlord
                  of its desire to do so, provided that such notice is given not
                  later than thirty (30) days after the  effective  date of such
                  taking.  If so much of the  Building  shall be so  taken  that
                  continued  operation  of the  Building  would  be  uneconomic,
                  Landlord  shall  have the  right to  terminate  this  Lease by
                  giving  notice  to Tenant  of  Landlord's  desire to do so not
                  later than thirty (30) days after the  effective  date of such
                  taking.


                                    (h)  Should any part of the  Premises  be so
                  taken or condemned during,  the Tenn, and should this Lease be
                  not  terminated in accordance  with the foregoing  provisions,
                  Landlord agrees to use due diligence to put what may remain of
                  the Premises (consistent,  however, with governmental laws and
                  codes  then in  existence)  and common  areas of the  Building
                  servicing  the  Premises  into  proper  condition  for use and
                  occupation as nearly like the condition of the Premises  prior
                  to such taking as shall be practicable.


                                    (i) If the Premises shall be damaged by fire
                  or other  casualty,  the Annual Fixed Rent and Additional Rent
                  shall be justly and equitably abated and reduced  according to
                  the nature and extent of the loss of use  thereof  suffered by
                  Tenant;   and  in  case  of  a  taking  which  temporarily  or
                  permanently   reduces  the  area  of  the  Premises,   a  just
                  proportion of the Annual Fixed Rent and Additional  Rent shall
                  be abated for the applicable portion or remainder, as the case
                  may be, of the Term.  In both cases,  above,  if any space not
                  damaged  or taken  nevertheless  becomes  unusable,  such fact
                  shall be taken into account when  calculating the rent for the
                  remaining space.


                                    (ii) In the event the  Premises  or Building
                  are damaged by fire or casualty and Landlord  either elects or
                  is  obligated  to  restore  the  same  pursuant  to any of the
                  foregoing  provisions of this Article VII, if Landlord has not
                  substantially  completed  (as that term is  defined in Section
                  3.1 hereof) such restoration  within six months of the date of
                  the  occurrence  of the fire or casualty  that has caused such
                  damage,  Tenant may terminate  this lease by written notice to
                  Landlord  given within ten business days after the end of such
                  six-month  period but in all events  prior to the time of such
                  substantial completion.


         7.2      Reservation of Award.

         Landlord  reserves to itself any and all rights to receive  awards made
for damages to the Premises and Building and Property and the  leasehold  hereby
created,  or any one or more of them,  accruing by reason of exercise of eminent
domain or by reason of anything  lawfully  done in  pursuance of public or other
authority. Tenant hereby releases and assigns to Landlord all Tenant's rights to
such awards,  and covenants to deliver such further  assignments  and assurances
thereof as Landlord may from time to time request.  It is agreed and understood,
however, that Landlord does not reserve to itself, and Tenant does not assign to
Landlord, any damages payable for (i) movable trade fixtures installed by Tenant
or  anybody  claiming  under  Tenant at its own  expense or  fixtures,  items or
leasehold  improvements,  whether  deemed realty or not, the removal of which is
required or permitted by any  agreement  given  pursuant to Sections 3.1 or 3.2,
and for which  Tenant  has paid the  entire  cost  thereof,  or (ii)  relocation
expenses recoverable by Tenant from such authority in a separate action.


                                                   ARTICLE VIII

                                                RIGHTS OF MORTGAGEE

         8.1      Superiority of Lease.

         Except as otherwise  provided in Section 8.6 below, this Lease shall be
superior to and shall not be  subordinated  to any  mortgage or other  voluntary
lien or other encumbrance arising after the date hereof on the Land or Building,
or both,  which are  separately  and together  hereinafter  in this Article VIII
referred to as "the mortgaged  premises."  The word  "mortgagee" as used in this
Lease  shall  include  the holder  for the time  being and any ground  lessor or
sublessor whenever the context permits.

         8.2      No Prepayment Payment.

         No fixed rent, additional rent, or any other charge shall be paid prior
to the due dates thereof and payments made in violation of this provision  shall
(except to the extent that such payments are actually received by a mortgagee in
possession  or in the process of  foreclosing  its  mortgage) be void as against
such  mortgagee  and Tenant  shall be liable for the amount of such  payments to
such mortgagee.

         8.3      No Release or Termination.

         No act or failure to act on the part of Landlord  which  would  entitle
Tenant  under the terms of this  Lease,  or by law,  to be  relieved of Tenant's
obligations  hereunder or to terminate this Lease,  shall result in a release or
termination of such obligations or a termination of this Lease unless (i) Tenant
shall have first given  written  notice of  Landlord's  act or failure to act to
Landlord's mortgagees of record, if any, specifying the act or failure to act on
the part of Landlord  which could or would give basis to  Tenant's  rights;  and
(ii) such  mortgagees,  after receipt of such notice,  have failed or refused to
correct or cure the condition complained of within a reasonable time thereafter;
but  nothing  contained  in this  Section  8.3 shall be  deemed  to  impose  any
obligation  on any  such  mortgagee  to  correct  or cure  any  such  condition.
Reasonable  times as used above means and includes a  reasonable  time to obtain
possession of the mortgaged  premises,  if the mortgagee  elects to do so, and a
reasonable  time,  not less  than  thirty  (30)  days,  to  correct  or cure the
condition if such condition is determined to exist.

         Notwithstanding  the  foregoing,   the  period  of  time  during  which
Landlord's  mortgagees shall have to cure the following  defaults or failures of
Landlord (should they occur):

(i) failure to provide power or other utility services or repairs required of
Landlord hereunder for a period in excess of twelve consecutive months as and to
the extent referred to in the last paragraph of subparagraph 5.2 above; and

          (ii) failure to substantially  complete restoration of the Building or
          Premises  after fire or casualty as and within the time  prescribed in
          subparagraph 7. 10) hereof;

          shall not be any longer  than the period of time  allotted to Landlord
          therefor under this Lease provided that (without  derogating  from any
          other  obligations or Tenant under this Lease) Tenant promptly deliver
          to each  such  mortgagee  of  record a copy of all  notices  and other
          communications  received  from and  which it  gives to  Landlord  with
          respect to any of the three foregoing enumerated matters.

         8.4      No Modification, etc.

         No  assignment  of this  Lease and no  agreement  to make or accept any
surrender,  termination or cancellation of this Lease and no agreement to modify
so as to reduce the rent,  change the Term, or otherwise  materially  change the
rights of Landlord under this Lease,  or to relieve Tenant of any obligations or
liability  under this Lease,  shall be valid  unless  consented to in writing by
Landlord's mortgagees of record, if any.


         8.5      Continuing Offer.

         The  covenants and  agreements  contained in this Lease with respect to
the rights, powers and benefits of a mortgagee (particularly, without limitation
thereby,  the covenants and agreement contained in this Article VIII) constitute
a  continuing  offer  to any  person,  corporation  or  other  entity,  which by
accepting or requiring an  assignment  of this Lease or by entry or  foreclosure
assumes the obligations  herein set forth with respect to such  mortgagee;  such
mortgagee is hereby constituted a party to this Lease as an obligee hereunder to
the same  extent  as  though  its name were  written  hereon  as such,  and such
mortgagee shall be entitled to enforce such provisions in its own name.

         8.6      Subordination.

         This Lease shall be subject and  subordinate  to any first  mortgage on
the  Building,  now or at any  time  hereafter  in  effect,  and to any  and all
advances  hereafter made thereunder,  and, in addition,  Landlord shall have the
option to  subordinate  this  Lease to any other  mortgage  which  includes  the
Premises  as part of the  mortgaged  premises,  provided  that the holder of any
mortgage of the nature  referred to in this Section 8.6 enters into an agreement
with  Tenant by the terms of which (a) in the event of  acquisition  of title by
such holder through foreclosure proceedings or otherwise, and provided Tenant is
not in default  hereunder to the extent that Landlord has the right to terminate
this Lease,  the holder will agree to recognize  the rights of Tenant under this
Lease  and to  accept  Tenant  as  tenant  of the  Premises  under the terms and
conditions of this Lease, subject to any rights of the Tenant regarding defaults
of the Landlord of which  Tenant has given  notice  pursuant to Section 8.3, and
(b) Tenant will agree to  recognize  the holder of such  mortgage as Landlord in
such event.  This  agreement  shall be made to  expressly  bind and inure to the
benefit  of the  successors  and  assigns  of Tenant  and of the holder and upon
anyone purchasing said Premises at any foreclosure sale.

         8.7      Implementation.

         Tenant  agrees on request  of  Landlord  to  execute,  acknowledge  and
deliver from time to time any agreement which may reasonably be deemed necessary
to effectuate the provisions of this Article VIII.

                                                    ARTICLE IX

                                                     DEFAULTS

9.1      Events of Default.

Each of the following shall be an Event of Default hereunder:

          (a)  If  Tenant  shall  default  in  the  performance  of  any  of its
          obligations  to pay  the  Annual  Fixed  Rent or any  Additional  Rent
          hereunder (a "monetary  default") and if such  monetary  default shall
          continue for ten (10) days after written  notice thereof (which notice
          for  the  purposes  of  this  paragraph  may  be  given  prior  to the
          expiration of the five (5) day period  referred to in Section 6. 1. 1,
          above);  (b) if within  thirty  (30) days after  written  notice  from
          Landlord to Tenant specifying any other default or defaults Tenant has
          not  commenced  diligently  to  correct  the  default or  defaults  so
          specified or has not thereafter  diligently pursued such correction to
          completion;  in the event (i) more than two written notices of default
          of the same type of obligation  are given in any calendar year or (ii)
          in the event more than five  written  notices of default of any nature
          are given in any  calendar  year,  then in either such  event,  Tenant
          shall pay to Landlord as rent and at the time the next rental  payment
          hereunder is due, the sum of One Thousand Dollars ($1,000.00) for each
          such notice in each such calendar year in excess of either two or five
          such notices as the case may be.

          (c) if any  assignment  shall be made by  tenant or any  guarantor  of
          Tenant for the benefit of creditors;

          (d) if Tenant's leasehold interest shall be taken on execution;

          (e) if a petition is filed by Tenant for  adjudication  as a bankrupt,
          or for  reorganization  or an  arrangement  under any provision of the
          Bankruptcy  Act as then in  force  and  effect,  or if an  involuntary
          petition under any of the  provisions of said  Bankruptcy Act is filed
          against Tenant and such  involuntary  petition is not dismissed within
          ninety (90) days thereafter.

                  Upon the  occurrence  of any Event of Default  then  remaining
uncured,  Landlord may  terminate  this Lease by notice to Tenant,  specifying a
date not less than ten (10) days after the  giving of such  notice on which this
Lease shall  terminate and this Lease shall come to an end on the date specified
therein as fully and completely as if such date were the date herein  originally
fixed for the  expiration of the Term of this Lease (Tenant  hereby  waiving any
rights of redemption  under MGLA c. 186,  ss.11),  and Tenant will then quit and
surrender  the  Premises  to  Landlord,   but  Tenant  shall  remain  liable  as
hereinafter provided.


         9.2      Remedies.

               (a) If this Lease shall have been  terminated as provided in this
               Article,  or if any  execution  or  attachment  shall  be  issued
               against Tenant or any of Tenant's property whereupon the Premises
               shall be taken or occupied  by someone  other than  Tenant,  then
               Landlord may,  without notice,  re-enter the Premises,  either by
               force,  summary proceedings,  ejectment or otherwise,  and remove
               and  dispossess  Tenant  and all  other  persons  and any and all
               property from the same,  as if this Lease had not been made,  and
               Tenant  hereby  waives the  service of notice by  Landlord of its
               intention to re-enter or to institute  legal  proceedings to that
               end.

               (b) In the event of any termination,  Tenant shall pay the Annual
               Fixed Rent,  Additional Rent and all other sums payable hereunder
               up to the time of such termination,  and thereafter Tenant, until
               the end of what  would  have  been the Term of this  Lease in the
               absence of such  termination,  and  whether  or not the  Premises
               shall have been relet, shall be liable to Landlord for, and shall
               pay to Landlord,  as liquidated current damages, the Annual Fixed
               Rent,  Additional  Rent and other  sums  which  would be  payable
               hereunder  if such  termination  had not  occurred,  less the net
               proceeds,  if  any,  of  any  reletting  of the  Premises,  after
               deducting  all  reasonable   expenses  in  connection  with  such
               reletting,   including,   without   limitation,   all  reasonable
               repossession  costs,  brokerage   commissions,   legal  expenses,
               attorneys, fees, advertising,  expenses of employees,  alteration
               costs and  expenses of  preparation  for such  reletting.  Tenant
               shall pay such  current  damages to Landlord  monthly on the days
               which the Annual Fixed Rent, Additional Rent and other sums would
               have  been   payable   hereunder  if  this  Lease  had  not  been
               terminated.

                    (c) At any  time  after  such  termination,  whether  or not
                    Landlord shall have collected any such current  damages,  as
                    liquidated  final  damages  and in lieu of all such  current
                    damages  beyond the date of such demand,  at the election of
                    Landlord  exercisable  at  any  time,  Tenant  shall  pay to
                    Landlord  an  amount  equal to the  excess,  if any,  of the
                    Annual Rent,. Additional Rent and other sums as hereinbefore
                    provided  which would be payable  hereunder from the date of
                    such  demand  (assuming  that,  for  the  purposes  of  this
                    paragraph,  annual  payments  by Tenant on  account  of Real
                    Estate Taxes and operating Expenses would be the same as the
                    payments required for the immediately preceding Operating or
                    Tax Year) for the  remainder  of the Term of this  Lease had
                    the same  remained in effect,  over the then fair net rental
                    value of the Premises for the same period.

                    (d) In case of any Default by Tenant,  re-entry,  expiration
                    and  dispossession  by  summary  proceedings  or  otherwise,
                    Landlord  may (i) acting,  reasonably  relet the Premises or
                    any part or parts thereof,  notwithstanding  that this Lease
                    may not have been terminated,  for a term or terms which may
                    at Landlord's  option be equal to or less than or exceed the
                    period which would otherwise have constituted the balance of
                    the Term of this  Lease  and may grant  concessions  or free
                    rent to the extent that  Landlord  considers  advisable  and
                    necessary   to  relet  the  same  and  (ii)  may  make  such
                    reasonable  alterations,  repairs  and  decorations  in  the
                    Premises  as  Landlord  in  its  sole   judgment   considers
                    advisable  and  necessary  for, the purpose of reletting the
                    Premises;  and the making of such  alterations,  repairs and
                    decorations  shall not  operate or be  construed  to release
                    Tenant from liability hereunder as aforesaid. Landlord shall
                    in no event be liable in any way  whatsoever  for failure to
                    relet the  Premises,  or, in the event that the Premises are
                    relet, for failure to collect the rent under such reletting.
                    Tenant  hereby  expressly  waives  any  and  all  rights  of
                    redemption granted by or under any present or future laws in
                    the event of Tenant being evicted or dispossessed, or in the
                    event of Landlord obtaining  possession of the Premises,  by
                    reason of the  violation  by Tenant of any of the  covenants
                    and conditions of this Lease.

                    (e) Landlord may invoke any remedy  (including the remedy of
                    specific  performance)  allowed  at law or in  equity  as if
                    specific remedies were not herein provided for.

                    (f) Upon the  occurrence  of an Event of Default  which is a
                    monetary  default (as defined in Paragraph 9. 1 (a),  above)
                    and notwithstanding that any other Event of Default which is
                    not a  monetary  default  shall  have  occurred  and  remain
                    uncured at the time; or upon the  termination  of this Lease
                    for  the  occurrence  of an  Event  of  Default  which  is a
                    monetary default,  notwithstanding that such termination may
                    also have  been  effected  because  of the  occurrence  of a
                    default  other than a monetary  default,  then and in either
                    such event,  in  addition to having the rights and  remedies
                    set forth in Paragraph  9.1 hereof and 9.2 hereof,  Landlord
                    may invoke any other  remedy and seek any other  damages not
                    specifically provided for in said Paragraphs 9.1 and 9.2.

                    Upon the  occurrence of one or more Events of Default,  none
                    of which is a monetary default (as defined in Paragraph 9. 1
                    (a) above);  or upon the  termination  of this Lease for the
                    occurrence  of one or more Events of Default,  none of which
                    is a  monetary  default,  then  and in  either  such  event,
                    Landlord's  rights,  remedies and damages on account of such
                    Event of  Default or  termination  shall be limited to those
                    set forth in Paragraph 9.1 and in Subparagraphs 9.2(a), (b),
                    (c), (d) and, to the extent of injunctive relief, (e) above.

                                                   MISCELLANEOUS

         10.1 Intentionally Deleted.

         10.2 Titles.

         The titles of the Articles are for  convenience  only and are not to be
considered in construing this Lease.

         10.3 Notice of Lease.

         Landlord and Tenant  agree that neither  party shall record this Lease.
Upon request of either party, both parties shall execute and deliver a notice of
this Lease in form appropriate for recording or registration,  and if this Lease
is  terminated  before  the  Lease  Term  expires,  an  instrument  in such form
acknowledging the date of termination.

         10.4 Holding Over.

         Any holding  over of the  Premises by Tenant  after the  expiration  or
earlier  termination  of the Term or any  extension  or renewal  thereof  shall,
subject to the  application  of the  provisions  of  Paragraph  10.  16,  below,
constitute  Tenant a trespasser of the Premises  unless prior to such expiration
or termination  Landlord has executed a written  instrument with Tenant in which
Landlord  agrees to an extension of the term of this I-ease.  If Tenant so holds
over,  Landlord by a written notice to Tenant may declare the Tenant a tenant at
will and the  tenancy so  created  may be  terminated  by not less than ten (10)
days,  written notice by either party to the other.  In the event Landlord makes
such  declaration,  the  tenancy  shall  be  subject  to all of  the  terms  and
provisions of this Lease except that it shall be  terminable  as above  provided
and the rent  during such  tenancy  shall be 150% of the total  average  monthly
rental payable by Tenant to Landlord for the  immediately  preceding  lease year
including but not limited to Annual Fixed Rent, and Additional  Rent as provided
in this Lease.

         10.5 Notice.

         Whenever any notice, approval, consent, request or election is given or
made pursuant to this Lease it shall be in writing, notwithstanding that certain
references in this Lease to requirements for notice may not call for the same to
be in writing.  Communications and payments shall be addressed if to Landlord at
Landlord's  Original Address or at such other address as may have been specified
by prior notice to Tenant,  and if to Tenant, at Tenant's Original Address prior
to the commencement date and thereafter at the Premises or at such other address
as may have been  specified by prior notice to Landlord  with a copy sent in the
case of notices to Tenant in the same manner and to the same  address  addressed
to "Corporate Counsel". Any communication or notice so addressed shall be deemed
duly served  when  delivered  in hand or upon  delivery  or  attempted  delivery
following deposit in the U.S. mail, registered mail, return receipt requested.

         10.6 Bind and Inure.

         The  obligations  of this Lease shall run with the land, and this Lease
shall be binding  upon and inure to the benefit of the parties  hereto and their
respective successors and assigns,  except that only the original Landlord named
herein  shall be liable for  obligations  accruing  before the  beginning of the
Term,  and thereafter  the original  Landlord  named herein and each  successive
owner of the Premises shall be liable only for the  obligations  accruing during
the period of its  ownership.  Whenever  the  Premises are owned by a trustee or
trustees,  the  obligations of Landlord shall be binding upon  Landlord's  trust
estate, but not upon any trustee or beneficiary of the trust individually.

         10.7 No Surrender.

         The delivery of keys to any employee of Landlord or to Landlord's agent
or any employee  thereof shall not operate as a  termination  of this Lease or a
surrender of the Premises.

         10.8 No Waiver, Etc.

         The failure of Landlord or of Tenant to seek redress for  violation of,
or to insist upon the strict  performance  of, any covenant or condition of this
Lease or any of the Rules and Regulations referred to in Section 6.1.4 shall not
be deemed a waiver of such  violation nor prevent a subsequent  act, which would
have originally constituted a violation, from having all the force and effect of
an original violation.  The failure of Landlord to enforce any of said Rules and
Regulations  against any tenant in the Building  shall not be deemed a waiver of
any such rules or  regulations,  but  Landlord  shall not enforce such Rules and
Regulations  inconsistently  or adopt  any new  rules or  regulations  which are
unreasonable.  The  receipt by Landlord  of fixed rent or  additional  rent with
knowledge  of the breach of any covenant of this Lease shall not be deemed to be
a waiver of such breach by Landlord,  unless such waiver be in writing signed by
Landlord. No consent or waiver,  express or implied, by Landlord or Tenant to or
of any breach of any agreement or duty shall be construed as a waiver or consent
to or of any other breach of the same or any other agreement or duty.

         10.9 No Accord and Satisfaction.

         No  acceptance  by  Landlord  of a lesser  sum than the fixed  rent and
additional  rent then due shall be deemed  to be other  than on  account  of the
earliest installment of such rent due, nor shall any endorsement or statement on
any check or any letter  accompanying  any check or payment as rent be deemed an
accord and  satisfaction,  and Landlord may accept such check or payment without
prejudice  to  Landlord's  right to recover the balance of such  installment  or
pursue any other remedy provided in this Lease.  Notwithstanding anything to the
contrary herein, in the event of a dispute,  Tenant may make any payment of rent
when due under protest but nothing shall relieve  Tenant of its  obligations  to
punctually and duly perform its obligations hereunder.

         10.10 Cumulative Remedies.

The specific  remedies to which  either  Landlord or Tenant may resort under the
terms of this Lease are  cumulative  and are not intended to be exclusive of any
other remedies or means of redress to which it may be lawfully  entitled in case
of any breach or threatened  breach by the other party of any provisions of this
Lease.  In addition to the other remedies  provided in this Lease,  Landlord and
Tenant shall be entitled to the  restraint  by  injunction  of the  violation or
attempted  or  threatened  violation  of  any of the  covenants,  conditions  or
provisions of this Lease or to a decree compelling  specific  performance of any
such covenants, conditions or provisions.

         10.11 Partial Invalidity and Applicable Law.

         This Lease shall be governed by and  construed in  accordance  with the
laws of The Commonwealth of  Massachusetts  and, if any provisions of this Lease
shall to any  extent  be  invalid,  the  remainder  of this  Lease  shall not be
affected thereby.  There are no oral or written  agreements between Landlord and
Tenant  affecting  this  Lease.  This Lease may be amended,  and the  provisions
hereof nay be waived or modified,  only by instruments  in writing.  executed by
Landlord and Tenant.

         10.12 Landlord's Right to Cure Tenant's Default.

         If  Tenant  shall  at  any  time  default  in  the  performance  of any
obligation  under this Lease,  Landlord  shall have the right,  but shall not be
obligated,   to  enter  upon  the  Premises  and  to  perform  such   obligation
notwithstanding  the fact  that no  specific  provisions  for  such  substituted
performance  by Landlord  are made in this Lease with  respect to such  default.
Except in case of emergency, these rights shall be exercised only after ten (10)
days prior written notice from Landlord to Tenant of Landlord's  intention to do
so. In  performing  such  obligation,  Landlord may make any payment of money or
perform any other act. All sums so paid by Landlord  (together  with interest at
an annual rate equal to the prime rate of interest  announced  from time to time
by  BankBoston,  N.A.,  plus  two  percentage  points  (2%)  and  all  necessary
incidental costs and expenses in connection with the performance of any such act
by Landlord shall be deemed to be additional  rent under this Lease and shall be
payable to Landlord  immediately on demand.  Landlord may exercise the foregoing
rights without  waiving any other of its rights or releasing  Tenant from any of
its obligations under this Lease.

         10.13 Estoppel Certificates.

Tenant shall from time to time, upon request by Landlord,  execute,  acknowledge
and deliver to Landlord or Landlord's designee a statement in writing certifying
that this Lease is  unmodified  and in full force and effect and that Tenant has
no defenses,  offsets or counterclaims  against its obligations to pay the fixed
rent and additional rent and to perform its other covenants under this Lease and
that there are no uncured  defaults of Landlord or Tenant  under this Lease (or,
if there have been any modifications,  that the same is in full force and effect
as  modified  and  stating the  modifications  and,  if there are any  defenses,
offsets,  counterclaims or defaults,  setting them forth in reasonable  detail),
and the dates to which the fixed rent,  additional  rent and other  charges have
been paid. Any such statement  delivered  pursuant to this Section 10. 13 may be
relied  upon by any  prospective  purchaser  or  mortgagee  of the  Building  or
Property.

         Landlord  shall  from time to time upon  request  of  Tenant,  execute,
acknowledge and deliver to Tenant, or Tenant's designee,  a statement in writing
reciting (to the extent  Landlord  acting  reasonably  considers  the same to be
accurate)  that this Lease is unmodified  and in full force and effect;  that no
moneys are due from Tenant to Landlord  hereunder;  that Tenant has not asserted
in writing any offsets  against payment of the rent or other sums due hereunder,
and that no notice of default given by Landlord to Tenant remain outstanding.

         10.14 Waiver of Subrogation.

         Any insurance  carried by either party with respect to the Premises and
property  therein or occurrences  thereon shall,  if the other party so requests
and if it can be so written without  additional  premium,  or with an additional
premium  which the other party  agrees to pay,  include a clause or  endorsement
denying to the  insurer  rights of  subrogation  against  the other party to the
extent  rights have been waived by the insured  prior to occurrence of injury or
loss. Each party,  notwithstanding any provisions of this Lease to the contrary,
hereby waives any rights of recovery against the other for injury or loss due to
hazards covered by insurance containing such clause or endorsement to the extent
of the greater of  indemnification  received  thereunder  or the full  insurable
value of the portion of the Premises so damaged.

         10. 15 Brokerage.

         Tenant warrants and represents  that,  except as hereinafter set forth,
it has not dealt with any real estate  broker or agent in  connection  with this
Lease or its  negotiation.  Tenant  represents that it has employed  Spaulding &
Slye as its broker at its own expense.  Tenant shall indemnify Landlord and hold
Landlord harmless from any cost,  expense or liability  (including costs of suit
and reasonable attorney's fees) for any compensation, commission or fees claimed
by Spaulding & Slye or any other real estate broker or agent in connection  with
this Lease or its negotiation by reason of any act of Tenant.  Landlord warrants

connection with this Lease or its  negotiation,  and shall indemnify  Tenant and
hold Tenant harmless from any costs,  expense or liability  (including  costs of

claimed  by any real  estate  broker or agent  other  than  Spaulding  & Slye in
connection with this Lease or its negotiation by reason of any act of Landlord.

         10.16 Force Majeure.

         Except  to the  extent,  if any,  otherwise  specifically  provided  in
Articles  III,  V and VII,  above,  in any case  where  either  party  hereto is
required to do any act, and is prevented or delayed in its  performance  thereof
by or  resulting,  from an act of  God,  war,  civil  commotion,  fire or  other
casualty,  labor  difficulties,  shortages  of labor,  materials  or  equipment,
governmental  regulations,  act of the other party,  or other causes beyond such
party's reasonable control (other than financial inability),  the period of time
during,  which it is so prevented or delayed shall not be counted in determining
the  time  during  which  such  act is to be  performed,  whether  such  time be

         10. 18 Parking.

         Landlord shall provide Tenant with parking,  as hereinafter  set forth,
upon payment of the then  monthly rate for parking  spaces in the area(s) on the
property  designated  by the  Landlord  for  parking.  The monthly rate for each
parking  space shall be $190.00 per month for the one year period  beginning  on
the Term  Commencement  Date and shall thereafter be the prevailing  market rate
for parking  spaces in garages in  comparable  buildings  located in the area of
Cambridge,  Massachusetts  where the Building is located.  Tenant shall abide by
any and all reasonable parking  regulations and rules established by Landlord or
Landlord's parking operator. Tenant shall be provided with one (1) parking space
for every 1,000  p.s.f.  of the  Premises.  A fraction  of 1/2 or greater  shall
entitle  Tenant to a full  parking  space.  Tenant  shall  specify the number of
spaces  required from time to time, up to its permissible  maximum,  upon thirty
(30) days' advance  written notice to Landlord and shall pay the charge therefor
from and after the date of delivery of such space.  In the event Tenant does not
require the use of all of its  permissible  maximum  number of parking,  spaces,
Landlord may  allocate  unused  parking  spaces to other  users,  provided  such
parking  spaces  shall be made  available to Tenant  within  thirty (30) days of
Tenant's notice that such parking spaces are required.

         10.19 Building Directory.  Tenant shall have the right to not more than
Tenant's then percentage of the rentable area of the Building,  calculated as in
Section 4.2.4,  above,  of the listings on the lobby  directory of the Building.
The  listing  of one or more names of  persons  other than  Tenant on such lobby
directory  shall not be construed as a consent by Landlord to an assignment or a
subletting by Tenant to such person or persons. Landlord agrees while this Lease
is in effect (i) not (of its own  initiative)  to change the present  address of
the Building,  and (ii) not to name the Building after a business  competitor of
Tenant.

         10.20 Tenant's Right to Cure.

         If Landlord  defaults in the  performance  or  observance of any of its
covenants or  obligations  set forth in this Lease,  Tenant shall give  Landlord
notice  specifying in what manner  Landlord has defaulted and if Landlord  shall
not within twenty (20) days of such notice  commence and  thereafter  diligently
pursue to completion the cure of such default (except that if such default shall
render the Premises or any part thereof  exceeding  twenty percent (20%) thereof
unusable for the Permitted Uses or shall  constitute an immediate danger to life
or  property  the initial  twenty (20) day period  described  above  shall,  for
purposes  of this  paragraph,  be  deemed  to be three  (3)  days),  Tenant  may
forthwith cure the same and invoice  Landlord for costs and expenses  (including
reasonable  attorneys'  fees and court  costs)  incurred by Tenant in curing the
same,  together with interest from the date Landlord  receives Tenant's invoice,
at a rate equal to the lesser of two  percent (2 %) over the base rate in effect
from time to time at BankBoston,  N.A. or the maximum rate allowed by law. In no
event,  however,  shall  such right to  reimbursement  give rise to any right of
setoff  or other  reduction  of the rent or any  other  sum due from  Tenant  to
Landlord  hereunder,  Tenant's  sole remedy being the right to bring a separate,
independent suit against Landlord for such reimbursement.

         10.21 Certain Other Matters.

                    (a)  Insofar  as the  same  relate  to the  Premises  or the
                    Building,  Tenant  agrees  to comply at all times at its own
                    expense  with all  Federal,  State and  local  environmental
                    protection laws, so-called,  and all rules,  regulations and
                    ordinances  relating thereto,  including without limitation,
                    Massachusetts General Laws c. 21E, the Federal Comprehensive
                    Environmental  Response  Compensation and Liability Act, the
                    Federal  Resource  Conservation  and  Recovery  Act  and all
                    amendments thereto.

                    (b) Tenant will  neither  permit nor suffer the  presence of
                    any  hazardous  materials (as that term is defined in any of
                    the  foregoing  statutes) on the premises at any time except
                    only for  reasonable  amounts  of  customarily  used  office
                    supplies  and  cleaning   materials  and,  upon  request  of
                    Landlord,  will  deliver  to  Landlord a list  reciting  the
                    identity and quantity of all such hazardous materials on the
                    premises.  Tenant will make no unlawful use of any hazardous
                    materials  and will neither  suffer nor permit any threat of
                    release, release or any other improper discharge thereof. If
                    any  threat  of  release  or  release  occurs,  Tenant  will
                    promptly  remediate  the  same  at its  own  expense  and in
                    accordance  with all  applicable  law.  In the event  Tenant
                    receives any notice from any regulatory agency or other such
                    party  requiring any action with respect to the  remediation
                    of any  threat  of  release  or  release  of  any  hazardous
                    materials,   Tenant  will  promptly  fully  notify  Landlord
                    thereof.  Tenant will  indemnify and save Landlord  harmless
                    from all loss, cost and expense Landlord may suffer or incur
                    in  connection  with the failure of Tenant to perform any of
                    its obligations hereunder,  the provisions of this paragraph
                    to survive and remain  operative  after  termination of this
                    Lease for any reason.

                    (c) Landlord  agrees to indemnify  and save Tenant  harmless
                    from all loss,  cost and expense  Tenant may suffer or incur
                    by virtue of any  violation  by Landlord  of any law,  rule,
                    regulations  or  ordinance  referred  to in (a) above to the
                    extent of any personal  injury or property damage or cost to
                    Tenant of any remediation activity Tenant by law is required
                    to  perform.  In the event  Tenant  suffers any such loss by
                    virtue of the activity of any other tenant in the  Building,
                    Landlord at Tenant  expense  will  enforce such rights as it
                    has  against  such  Tenant,  the  result of which will be to

                                                     EXHIBIT C

                                        DETERMINATION OF FAIR RENTAL VALUE

         In the event the Fair Rental  Value of the  Additional  Premises or the
Premises  during  any  Additional  Term must be  determined  by  appraisal,  the
determination of Fair Rental value shall be made:

                    (i)  by  an  appraiser  chosen  by  agreement   between  the
                         parties; or

                    (ii) if the parties  shall not agree on an appraiser  within
                         thirty (30) days after the period for agreement on Fair
                         Rental  Value has  elapsed,  by taking  the  arithmetic
                         average of the value assigned by three appraisers,  one
                         selected by each of the parties, and the third selected
                         by  agreement  of  the  two   appraisers  so  selected;
                         provided  that, if the appraised  value assigned by any
                         appraiser selected by a party shall be less than ninety
                         percent  (90%),  or more than one  hundred  ten percent
                         (110 %) of the  appraised  value  assigned by the third
                         appraiser, then such first value shall, for purposes of
                         this subparagraph, be increased to ninety percent (90%)
                         or  decreased  to one hundred  ten percent  (110 %), as
                         applicable,  of the  appraised  value  assigned by such
                         third  appraiser.  All  appraisers  referred to in this
                         Exhibit  shall be  M.A.I.  appraisers  with at least 10
                         years of experience  appraising  commercial real estate
                         in the greater Boston area. The costs of each appraiser
                         shall be borne by the party  appointing  him, or in the
                         case of a third  appraiser,  shall be shared equally by
                         the  parties.  In the event that either  party fails to
                         appoint  an  appraiser  pursuant  to this  subparagraph
                         within  thirty (30) days after the period for agreement
                         of Fair Rental Value has elapsed,  then the  appraiser,
                         if any,  appointed by the other parties  shall,  acting
                         singularly,  make  the  determination  of  Fair  Rental
                         Value.  If the two appraisers  appointed by the parties
                         do not within a period of  fifteen  (15) days after the
                         appointment  of the  later  of  them,  appoint  a third
                         appraiser  willing  so to act,  then  either  party may
                         designate instead that the third appraiser be appointed
                         by the American  Arbitration  Association  (pursuant to
                         its then applicable rules) or a successor  organization
                         thereto (unless any party or business associate thereof
                         holds  such a  position,  in  which  event  said  third
                         appraiser  shall be appointed by the person holding the
                         next  highest  position  on  said  Board  who  is not a
                         business  associate of any party) and the individual so
                         appointed shall for all purposes have the same standing
                         and powers as though he had been  seasonably  appointed
                         by the appraisers first appointed. The appraisers shall
                         be  instructed  that  the  foregoing  appraisals  shall
                         reflect any anticipated  increase in the rental payable
                         between  the  date of the  appraisers,  report  and the
                         first day of the extended term and that in  determining
                         the same they may (but need not) take into  account any
                         appropriate nationally recognized consumer Price Index.
                         Such  appraisals  shall also take into account the fact
                         that the  portion  of the rental  subject to  appraisal
                         which is  included  in Tenants  Included  Share of Real
                         Estate  Taxes and  Operating  Expenses  (referred to on
                         page 3  above)  by  their  own  terms  are  subject  to
                         increase. The appraisers shall also considers all other
                         relevant   factor  .  No  rental   increase   shall  be
                         attributable  to the  value of or the  right to use any
                         improvements  paid for by Tenant (and not reimbursed by
                         Landlord) and installed after  commencement of the term
                         of the Prior Lease. Each appraiser  appointed hereunder
                         shall acknowledge in writing an obligation hereunder to
                         reach a  decision  no later  than 30 days  after  their
                         appointment.

                                                   OFFICE LEASE

         THIS LEASE (the "Lease") is made,  entered into and effective as of the
31st day of March,  1997,  between George H. Beuchert,  Jr., Trustee,  Thomas J.
Egan, Trustee,  Oliver T. Carr, Jr., Trustee,  William Joseph H. Smith, Trustee,
and The Kiplinger  Washington  Editors,  Inc.,  Trustee,  acting collectively as
trustees on behalf of the beneficial owner, The Greystone Square 127 Associates,
a District of Columbia  limited  partnership,  (collectively  the  "Lessor") and
Putnam, Hayes & Bartlett, Inc., a Massachusetts corporation, (hereinafter called
"Lessee").

         WITNESSETH,  That,  for  and  in  consideration  of the  rents,  mutual
covenants,  and agreements  hereinafter set forth,  the parties hereto do hereby
mutually agree as follows:

1.        DEMISED PREMISES

         (A) Lessor does hereby  lease to Lessee,  and Lessee does hereby  lease
from Lessor,  for the term and upon the  conditions  hereinafter  provided,  the
following spaces:

                  (i) a space identified as approximately 36,265 rentable square
                  feet on the fifth and sixth  (5th & 6th)  floors of the office
                  building situated at 1776 Eye Street, N.W.,  Washington,  D.C.
                  20006  (such  building  being  hereinafter  referred to as the
                  "Building"),  having been  previously  assigned Suite Nos. 500
                  and  600  respectively   (collectively   referred  to  as  the
                  "Original Premises"); and,

                  (ii) a space identified as approximately 8,851 rentable square
                  feet on the  fifth  (5th)  floor of the  Building,  previously
                  identified  as Suite  No.  575  (hereinafter  the  "Additional
                  Premises").


         (B) The Original  Premises and the Additional  Premises are outlined on
the floor  plans  attached  hereto and made a part  hereof as Exhibit  A-1.  The
Original  Premises  and  the  Additional  Premises  are  hereinafter   sometimes
collectively referred to as the "Demised Premises," and have a combined rentable
area of  approximately  45,116  square feet.  As otherwise  provided for in this
Lease,  the term  "Demised  Premises" may be modified to include other spaces in
the  Building as leased by Lessee from time to time,  in which case the combined
rentable area of the Demised Premises may change.  The Original Premises and the
Additional Premises have been measured in accordance with the Washington,  D.C.,
Association of Realtors Standard Method of Measurement,  1983 Version. As of the
date of this Lease first hereinabove stated the Building contains  approximately
212,582   square  feet  of  rentable  area  of  office  and  retail  spaces  and
approximately  199,552  square feet of rentable  area of office  spaces.  Lessee
recognizes that the statement of rentable area for any space and of the Building
given  above are  approximate,  but that for the  purposes  of this Lease are an
accurate  statement of such areas;  by executing this Lease,  Lessee  recognizes
that it has had the  opportunity  to measure the  Original  Premises and that it
waives any right to challenge  subsequently  this  statement of  measurement  of
rentable  areas of the Original  Premises  and the  Building.  Lessor  agrees to
afford to Lessee the  opportunity to measure the area of the Additional  Demised
Premises prior to Commencement  Date 2 (as hereinafter  defined),  provided that
when Lessee executes and delivers Exhibit D-1 related to the Additional Premises
it shall be deemed Lessee's acceptance of the area of the Additional Premises as
stated  in  that  Exhibit.  As and to the  extent  that  Lessee  can  reasonably
demonstrate  to Lessor that Lessor's  determination  of the rentable area of the
Additional Premises  hereinabove stated is incorrect at that time, Lessor agrees
to modify the Lease.  to reflect the agreed upon rentable area of the Additional
Premises.

         (C) Lessor agrees to deliver and Lessee agrees to accept  possession of
the Demised Premises in its "as is" condition existing on the date possession is
delivered  to  Lessee,  without  requiring  Lessor  to make  any  modifications,
alterations,  repairs,  improvements, or decorations to be made to or demolition
of  existing  improvements  within  the  Demised  Premises,  provided  that  the
Additional  Premises  shall be delivered in broom clean  condition with any base
building  operating  equipment  in  the  Additional  Premises  being  in  normal
operating condition as and when delivered by Lessor to Lessee. Lessor shall have
no obligation to deliver any supplemental air conditioning,  heating ventilation
package units and kitchen  equipment in working order and condition.  Lessor has
agreed to  provide  to Lessee  the  Allowance  for the  Initial  Alterations  as
provided for and identified in the Section of this Lease entitled "ALTERATIONS."

         (D) Subject to the  provisions  of the  Section of this Lease  entitled
"DAMAGE TO THE BUILDING AND/OR THE DEMISED PREMISES," Lessor agrees that it will
deliver and keep from and after the Commencement Date 1 (as hereinafter defined)
all common and public areas of the Building,  the base  building  systems of the
Building and all external and structural  elements  thereof in safe and sanitary
condition,  in good working  order and  condition,  and in  accordance  with the
standards  customarily  employed by other  landlords of  comparable  first-class
office  buildings  located within the central  business  district of Washington,
D.C.,  including,  as  provided  for in  the  Section  of  this  Lease  entitled
"COMPLIANCE WITH THE AMERICANS WITH  DISABILITIES  ACT," ensuring  compliance of
common and public areas of the Building with ADA (as hereinafter defined).

         (E) (i)  Lessor  furthers  agrees  that,  if prior  to the date  Lessee
receives the right to lawfully  occupy the Original  Premises and the Additional
Premises for its regular  business  operations  upon  substantial  completion of
Initial  Alterations  (as  hereinafter  defined),  District  of  Columbia  plans
reviewing  officials  ("Reviewing  Officials"),  District of Columbia inspecting
officials  ("Inspecting  Officials"),  or both, determine that the base building
fire  and  life  safety  systems  of  the  Building  are in  noncompliance  with
applicable  codes of the  District  of  Columbia in effect as of January 1, 1997
(the  "Codes"),  and that such  condition  (a)  prevents  Lessee from  obtaining
permits and approvals  from the District of Columbia  necessary to permit Lessee
to  undertake  Initial  Alterations,   (b)  prevents  Lessee  from  subsequently
occupying the Additional  Premises after  completion of Initial  Alterations for
Lessee's regular business operations,  or (c) prevents Lessee from continuing to
use and occupy the Original  Premises for Lessee's regular  business  operations
from and after the date of  commencement  of Initial  Alterations,  then  Lessor
shall be responsible for those  modifications to the base building fire and life
safety  systems of the Building which are required to bring those systems into a
condition which, in accordance with the Codes, would permit Lessee to obtain the
necessary   permits  and  approvals  so  that  Lessee  may   undertake   Initial
Alterations,  would  lawfully  permit  Lessee to  lawfully  occupy the  Original
Premises for Lessee's regular business operation during  construction of Initial
Alterations,  and would  subsequently  permit  Lessee  to  lawfully  occupy  for
Lessee's  regular  business  operations  the Demised  Premises upon  substantial
completion of Initial Alterations (such necessary and required  modifications to
base building  fire and life safety  systems  being  hereinafter  referred to as
"Fire/Life Safety Modifications").

                  (ii) If at the time Lessee submits to the District of Columbia
applications  for  permits  and  licenses  to  undertake   Initial   Alterations
(collectively  "Permits"),  Reviewing  Officials determine that Fire/Life Safety
Modifications  are required to be made,  then Lessor agrees to use  commercially
reasonable  efforts  to  (a)  complete  the  then  identified  Fire/Life  Safety
Modifications,  or in lieu  thereof  (b)  reach  agreement  with  the  Reviewing
Officials  binding  upon Lessor  regarding  Lessor  undertaking  and  completing
Fire/Life Safety Modifications which permit the issuance of the Permits.  Lessor
shall notify Lessee in writing when Lessor has either  completed those Fire/Life
Safety  Modifications in accordance with the applicable codes of the District of
Columbia and has obtained all necessary  governmental  inspections and approvals
of such Fire/Life Safety Modifications,  or when Lessor has reached an agreement
with the Reviewing  Officials binding upon Lessor permitting the issuance of the
Permits (the "Completion Notice 1").

                  (iii) If after the  commencement  of  construction  of Initial
Alterations,  Inspecting  Officials  determine  that  certain  Fire/Life  Safety
Modifications  are required to be made in order to permit  Lessee to continue to
occupy the Original Premises for Lessee's regular business  operations or permit
Lessee to lawfully occupy the Additional  Premises and/or the Original  Premises
upon substantial  completion of Initial  Alterations,  then Lessor agrees to use
commercially  reasonable  efforts to (a)  complete  those  identified  Fire/Life
Safety  Modifications or in lieu thereof (b) reach agreement with the Inspecting
Officials  binding  upon Lessor  regarding  Lessor  undertaking  and  completing
Fire/Life  Safety  Modifications  so that Lessee can continue to lawfully occupy
the Original Premises or so that Lessee can obtain, upon substantial  completion
of Initial  Alterations.  the right to lawfully occupy the Additional  Premises,
and if applicable the Original  Premises.  Lessor shall notify Lessee in writing
when Lessor has completed in accordance  with the Codes those  Fire/Life  Safety
Modifications  identified  by the  Inspecting  Officials  and has  obtained  all
necessary  governmental  inspections  and  approvals for such  Fire/Life  Safety
Modifications  or when  Lessor has  reached  an  agreement  with the  Inspecting
Officials  binding upon Lessor  permitting  Lessee to lawfully  occupy  Original
Premises,  the  Additional  Premises  or  both  for  Lessee's  regular  business
operations  (the  "Completion  Notice  2").  Completion  Notice 2 shall  only be
required  to be given by Lessor  if  Lessor  has been  advised  by  Lessee  that
Fire/Life  Safety  Modifications  have been required by Inspecting  Officials in
order to permit Lessee to lawfully occupy,  or continue to lawfully occupy,  the
Additional Premises, the Original Premises or both.

         (F) Notwithstanding  Lessor's  obligations to make any Fire/Life Safety
Modifications  identified  by  Reviewing  Officials or  Inspecting  Officials in
connection  with the Initial  Alterations as specified in Subsection (E) of this
Section,  Lessor shall have no  obligation to undertake any fire and life safety
improvements to or within the Demised Premises. If however (i) Lessor undertakes
any fire and life safety  improvements  to or within any premises  leased to any
other  office  tenant(s)  of the  Building  prior to  January  1,  2002 and such
improvements  are of a nature  similar or comparable to the fire and life safety
improvements undertaken by Lessee as part of Initial Alterations,  (ii) the cost
of such  improvements  is not paid for by the tenant in question,  and (iii) the
aggregate  of the  rentable  areas of all  premises in the  Building  leased for
office uses in which Lessor has undertaken  such  improvements,  at other than a
tenant's cost,  exceeds  twenty-five  percent (25 %) of the rentable area of the
Building  dedicated to office uses, Lessor shall reimburse Lessee for the direct
costs actually incurred by Lessee at the time it undertook  Initial  Alterations
to  per-form  its  fire  and life  safety  improvements  which  are  similar  or
comparable  to those  undertaken  by Lessor  for  other  office  tenants  of the
Building thereafter.

         (G) Lessee represents that it has thoroughly  examined the Building and
the Original Premises and is aware of and accepts the existing  condition of the
Original  Premises  and  the  Building,  subject  to  Lessor's  obligations  for
Fire/Life Safety Modifications as specified in Subsection (E) of this Section.

2.       TERM

         (A) Subject to and upon the  covenants,  agreements  and  conditions of
Lessor and Lessee set forth herein,  or in any Exhibit or Addendum  hereto,  the
term of this  Lease  with  regard to the  Demised  Premises  shall  commence  as
follows:

                  (i) With regard to the  Original  Premises,  on the 1st day of
                  January,  1997 (hereinafter called the "Commencement Date I");
                  and,

                  (ii) With regard to the Additional  Premises,  on the later of
                  (a) April 21,  1997,  or (b) the date  thereafter  that Lessor
                  delivers  the  Additional   Premises  to  Lessee  in  Delivery
                  Condition  (either  to occur of (a) or (b)  being  hereinafter
                  called the "Commencement Date 2").

To effect  delivery and trigger the  occurrence of  Commencement  Date 2, Lessor
must  deliver the  Additional  Premises  free and clear of all  occupancies  and
tenancies,  must have  brought  all base  building  operating  equipment  in the
Additional   Premises  (and   specifically.   not  including   supplemental  air
conditioning,  heating and ventilation  package units and kitchen  equipment) to
normal  operating  condition and must deliver the  Additional  Premises in broom
clean condition (the "Delivery Condition").

                           (B) The term of this Lease with regard to the Demised
Premises shall expire on the
31st day of December, 2006.

         (C)  In the  event  Lessor  is  unable  to  deliver  possession  of the
Additional  Premises  to Lessee in the  Delivery  Condition  by April 21,  1997,
Lessor shall not be liable or responsible for any claims, damages or liabilities
arising  in  connection  therewith  or by reason  thereof,  nor shall  Lessee be
excused or released  from this Lease,  because of Lessor's  inability to deliver
the  Additional  Premises to Lessee by such date.  Commencement  Date 2 shall be
extended  to  and  become  the  date  that  Lessor  delivers  possession  of the
Additional Premises to Lessee in the Delivery Condition.  If Commencement Date 2
does not occur  until a date after May 31,  1997 due to  Lessor's  inability  to
deliver  possession  of the  Additional  Premises  to  Lessee  in  the  Delivery
Condition,  then,  as  provided in  Subsection  (F) of the Section of this Lease
entitled  "RENT,  " Lessee shall be entitled to and Lessor shall  recognize as a
credit  to  Monthly  Rent  2  (as  hereinafter   defined)  accruing  after  Rent
Commencement Date 2.

         (D)  Notwithstanding  the provisions of Subsection (C) of this Section,
if Lessor is unable to deliver the Additional Premises to Lessee in the Delivery
Condition by August 31, 1997, Lessee shall have the option to cancel this Lease,
provided  written  notice  thereof is delivered to Lessor prior to the time that
Lessor  delivers the  Additional  Premises to Lessee in the Delivery  Condition.
This  Lease  shall be deemed  canceled  as of the date of  receipt  by Lessor of
Lessee's  notice of cancellation  to Lessor.  If Lessor tenders  delivery of the
Additional  Premises to Lessee in the Delivery  Condition prior to the time that
Lessee delivers a written notice of cancellation to Lessor,  this Subsection (D)
shall be deemed  automatically  null and void and Lessee  shall have no right to
refuse to accept delivery of the Additional Premises or further right to seek to
cancel this Lease.

         (E) (i) In the event that (a) Lessee  cannot  obtain  Permits  from the
Reviewing  Officials due to the failure of Lessor to complete  Fire/Life  Safety
Modifications  or Lessor's  failure to reach agreement with Reviewing  Officials
binding  upon  Lessor  regarding  Lessor's   undertaking  and  completing  those
Fire/Life Safety Modifications, as provided for in Subsection (E) of the Section
of this  Lease,  entitled  "DEMISED  PREMISES,"  (b) Lessee  cannot  continue to
lawfully  occupy and use all or a substantial  portion of the Original  Premises
from and after the date that  construction of Initial  Alterations is commenced,
or (c) Lessee cannot lawfully occupy,  as of the date of substantial  completion
of the Initial  Alterations,.  the  Additional  Premises and, if applicable  the
Original Premises, due to the failure of Lessor to complete the Fire/Life Safety
Modifications  or reach  agreement  with the  District of Columbia  binding upon
Lessee   regarding   Lessor's   undertaking  and  completing   Fire/Life  Safety
Modifications,  as provided for in Subsection  (E) of the Section of this Lease,
entitled  "DEMISED  PREMISES," then in addition to any abatement of certain rent
as provided for in Subsection (G) of the Section of this Lease entitled "MONTHLY
RENT," Lessee shall have the right to cancel this Lease as hereinafter  provided
in this Subsection.

                  (ii) If (a) Lessee is legally  prevented  from  obtaining  the
Permits  solely due to the fact that Lessor has not  previously  undertaken  the
Fire/Life Safety Modifications identified by Reviewing Officials, or that Lessor
has not agreed with Reviewing Officials on Fire/Life Safety  Modifications to be
made, and the delay in issuance of Permits extends for more than sixty (60) days
after the date that Lessee has advised  Lessor that the Reviewing  Officials are
requiring Lessor to undertake  Fire/Life Safety  Modifications as a condition to
issuance  of the  Permits,  (b) Lessee is legally  prevented  by the  Inspecting
Officials  from  lawfully  occupying  the  Additional  Premises  for its regular
business  operations  solely due to the fact that Lessor has not  undertaken the
Fire/Life  Safety  Modifications   identified  by  Reviewing  Officials  or  the
Inspecting  Officials,  or that Lessor has not reached agreement with Inspecting
Officials on Fire/Life Safety Modifications to be made, and thus Lessee's lawful
occupancy  for its regular  business  operations is delayed for a period of more
than sixty (60) days following the date Lessor receives Lessee's notice advising
Lessor that Inspecting  Officials have identified Fire/Life Safety Modifications
that must be  undertaken  as a condition  to the  issuance of a  certificate  of
occupancy for the Additional Premises (or the Demised Premises,  if applicable),
or (c)  Lessee's  lawful  occupancy  of the  Original  Premises  for its regular
business  operations is disrupted by Inspecting  Officials after commencement of
Initial  Alterations  solely due to the fact that Lessor has not undertaken,  as
and when required,  the Fire/Life Safety  Modifications  identified by Reviewing
Officials or the Inspecting Officials,  or that Lessor has not reached agreement
with  Inspecting  Officials on Fire/Life  Safety  Modifications  to be made, and
this-disruption  continues  for a period of more than fifteen  (15)  consecutive
business days following the date that Lessor  receives  Lessee's notice that the
Inspecting  Officials  have  ordered  that  Lessee  cease  to  occupy  all  or a
substantial  portion of the  Original  Premises for  Lessee's  regular  business
operations, then Lessee may elect to cancel this Lease as hereinafter provided.

(iii)Lessee may  exercise  this  right to cancel  only by  delivering  to Lessor
     written notice of such election to cancel this Lease,  which notice must be
     received by Lessor  within  fifteen (15)  business days after the date that
     Lessee is first  entitled to exercise  this right to cancel and in any case
     such notice to be  effective  must be delivered to Lessor prior to the date
     that Lessor delivers to Lessee  Completion Notice 1 or Completion Notice 2,
     as applicable.  If Lessee has not delivered its notice of  cancellation  by
     the  earlier  of (a)  the  time  Lessee  receives  Completion  Notice  1 or
     Completion  Notice 2, as  applicable,  or (b) the expiration of the fifteen
     (15) day period,  then this  option to cancel this Lease shall  become null
     and void. If Lessee timely and properly  exercises its right to cancel this
     Lease as provided  above,  Lessee  shall be entitled  to be  reimbursed  by
     Lessor for all costs,  direct and indirect,  incurred by Lessee  related to
     this  transaction,   including  the  costs  and  expenses  of  the  Initial
     Alterations  incurred by Lessee, less, however, the amount of any Allowance
     paid over by Lessor to Lessee or to  Lessee's  contractors,  suppliers  and
     vendors on Lessee's behalf. As consideration for such payment, Lessee shall
     assign over to Lessor all right,  title and  interest in and to any and all
     of the Initial Alterations, including any furniture, fixtures and equipment
     purchased  by or for Lessee with the  Allowance,  all of which shall become
     Lessor's property as of the effective date of cancellation.


         (F) (i) In the event that Lessee  timely and properly  exercises one of
the its rights to cancel this Lease afforded in Subsection (D) or Subsection (E)
of this Section  above,  and except  where Lessee  cancels this Lease due to the
fact that it is legally prohibited from lawfully occupying the Original Premises
or a  substantial  portion  thereof  (as  such  term  "substantial  portion"  is
hereinafter  defined -in  Subsection  (G) of the Section of this Lease  entitled
"RENT") for its  regular  business  operations  due the lack of  completion,  or
agreement on completion,  of Fire/Life Safety  Modifications,  Lessor and Lessee
shall recognize that certain office lease for the Original Premises,  dated July
8, 1988, by and between Lessor and Lessee, as amended to the date of this Lease,
(the "Original Lease"),  and the Original Lease shall be reinstated as if it had
continued in full force and effect through Commencement Date 1, and Lessee shall
be  permitted  to continue to lease the Original  Premises  through  October 31,
1998, as and to the extent provided for in the Original Lease. Lessee shall have
no rights thereafter to the Additional Premises, nor to any rights arising under
this Lease,  this Lease being  deemed null and void as of the date of receipt by
Lessor of  Lessee's  notice  of  cancellation  to  Lessor.  If this  Lease is so
canceled,  Lessor,  by such  cancellation  action,  shall be  liable  under  the
Original  Lease for all  Monthly  Rent and  additional  rent  arising  under the
Section of the Original  Lease  entitled  "RENTAL  ESCALATION  FOR  INCREASES IN
EXPENSES,"  which would have accrued from and after January 1, 1997, but for the
termination of the Original Lease. Against that accrued liability,  Lessee shall
be given credit for any Monthly  Rent paid by Lessee to Lessor  pursuant to this
Lease. Lessee shall pay any deficiency within thirty (30) days after the date of
receipt of Lessor's  notice to Lessee  advising Lessee of the amount of any such
deficiency.  In the event that this Lease is cancelled  and the  Original  Lease
reinstated due to Lessee's inability to have access to the Additional  Premises,
Lessor agrees  thereafter to cooperate with Lessee to seek to provide Lessee, at
Lessee's sole option, with interim office space in the Building of rentable area
approximately  the rentable  area of the  Additional  Premises to meet  Lessee's
needs as of the applicable cancellation date. If such space is provided,  Lessee
agrees to lease  such  space  upon the  terms of the  Original  Lease,  with the
monthly rent for such area being based upon the effective rental rate per square
foot per  month  then in  effect  under  the  Original  Lease  for the  Original
Premises.  Lessee  will  lease  such  space  in its  "as is"  condition  without
requiring any changes or modifications by Lessor.

          (ii) Where Lessee is prevented  from  lawfully  occupying the Original
Premises for its regular business  purposes due to Lessor's failure to complete,
or in lieu  thereof  failure to reach  agreement  to complete  Fire/Life  Safety
Modifications,  the cancellation of this Lease by Lessee through the exercise of
its rights under  Subsection  (E) of this Section shall also serve to cancel the
Original  Lease.  In that  instance and within thirty (30) days after the timely
delivery to Lessor of the notice of cancellation arising due to Lessee's lose of
its lawful right to occupy the Original  Premises  because of the absence of, or
lack of agreement upon Fire/Life Safety  Modifications,  Lessee shall vacate the
Original  Premises  and the  Additional  Premises as if the Lease had  naturally
expired at the end of its initial term and any ongoing obligations of Lessor and
Lessee shall be governed solely by the provisions of this Lease.

         (G) When Lessee and Lessor have  executed  this Lease and Lessee  holds
possession of the Original  Premises  pursuant to this Lease,  Lessor and Lessee
shall  execute  the  "Declaration  as to  Date of  Delivery  and  Acceptance  of
Possession  of Original  Premises,  " attached  hereto as Exhibit D. When Lessee
accepts possession of the Additional  Premises,  Lessor and Lessee shall execute
the  "Declaration  as to  Date of  Delivery  and  Acceptance  of  Possession  of
Additional  Premises,  " attached  hereto as Exhibit  D-1,  which shall  specify
Commencement  Date 2. Execution of this document shall not be deemed a condition
to the occurrence of Commencement Date 2.

(H)  If Lessee has the right to cancel this Lease  pursuant to Subsection (E) of
     this Section, and if the Codes would permit Lessee to construct the Initial
     Alterations and  subsequently  to lawfully  occupy the Demised  Premises if
     interim  fire  and  life  safety  devices  were  installed  in the  Demised
     Premises,  then Lessee may, in lieu of cancellation of this Lease, and with
     Lessor's prior approval, which approval may not be unreasonably withheld or
     delayed,  modify the Initial  Alterations  to include  installation  of the
     interim fire and life safety devices in the Demised  Premises  permitted by
     the  Codes  so  that  Lessee  can  construct   Initial   Alternations   and
     subsequently  lawfully use and occupy the Demised Premises,  without Lessor
     first having  completed the Fire/Life  Safety  Modifications or alternately
     reached an  agreement  with the  District of Columbia  binding  upon Lessor
     related to Fire/Life Safety Modifications.  By Lessee undertaking such work
     and installing as applicable  such interim  devices,  Lessee  automatically
     waives  its right to cancel  this  Lease as  otherwise  afforded  to Lessee
     pursuant to Subsection (E) above of this Section. If Lessee does modify the
     Initial Alterations to include approved interim devices that will permit it
     to  lawfully  occupy  the  Demised  Premises,  then at such  time as Lessor
     completes  the  Fire/Life  Safety  Modifications,  Lessor shall pay for the
     costs of (i)  connection to base building fire and life safety  systems and
     (ii) any retrofitting of the fire and life safety improvements installed by
     Lessee in the Demised  Premises as part of the Initial  Alterations,  which
     are  necessary  for  Lessee's  continued  lawful  occupancy  of the Demised
     Premises for Lessee's  regular business  operations.  Lessor shall also pay
     for the  reasonable  costs of  patching  and  repairing  damage  to  tenant
     improvements  in the Demised  Premises  including the Initial  Alterations,
     caused  by  removal,  if  necessary,  of the fire and life  safety  interim
     devices.


3.       USE

         Lessee  shall use and occupy the  Demised  Premises  solely for general
office  purposes in  accordance  with the  applicable  zoning  regulations.  The
Demised  Premises  shall not be used for any  other  purpose  without  the prior
written consent of Lessor.  Lessee shall not use or occupy the Demised  Premises
for any  unlawful  purpose,  and will comply  with all present and future  laws,
ordinances,  regulations, and orders of all governments, government agencies and
any other public authority having jurisdiction over the Demised Premises. Lessee
may not use, store or dispose of any hazardous materials on or about the Demised
Premises,  except as  necessary  to the normal  and  ordinary  operation  of its
business in the Demised Premises,  and then such use, storage and disposal shall
only be in accordance with applicable environmental rules and regulations.


4.       RENT

         (A) Lessee  covenants  and agrees to pay to Lessor  rent of any kind or
nature,  including Monthly Rent 1 (as hereinafter  defined),  Monthly Rent 2 (as
hereinafter  defined) and any sums,  charges,  expenses and costs  identified in
this  Lease  as  additional  rent to be  paid  by  Lessee  to  Lessor.  Lessee's
obligation to pay rent for the Original Premises shall begin on the Commencement
Date I (hereinafter the "Rent Commencement Date I "); Lessee's obligation to pay
rent for the  Additional  Premises shall begin on the date that is three hundred

designate  from time to time by  written  notice to Lessee,  without  demand and
without deduction, set-off or counterclaim. If Lessor shall at any time or times
accept rent after it shall become due and  payable,  such  acceptance  shall not
excuse delay upon  subsequent  occasions,  or constitute,  or be construed as, a
waiver of any or all of Lessor's rights hereunder.

         (B) The initial  monthly  rent for the Original  Premises  (hereinafter
referred to as "Monthly  Rent 1") as of Rent  Commencement  Date 1, which Lessee
hereby  agrees to pay in advance to Lessor and Lessor  hereby  agrees to accept,
shall be One Hundred Two Thousand  Seven  Hundred  Fifty and  83/100ths  Dollars
($102,750.83). The initial monthly rent for the Additional Premises (hereinafter

adjustment as provided in the Section of this Lease entitled "ANNUAL  ESCALATION
OF MONTHLY RENT." The term "Monthly Rent" shall mean collectively Monthly Rent 1
and Monthly Rent 2 as specified above and as subsequently  adjusted  pursuant to
the operation of that Section of this Lease or as otherwise modified in response
to Lessee's exercise of any rights to lease other space in the Building pursuant
to this Lease.

         (D) Monthly Rent as specified  above shall be payable in advance on the
first day of each  calendar  month during the term of this Lease  following  the
applicable Rent Commencement Date. Additionally, Lessee shall be credited toward
the  payment  of  Monthly  Rent  first due and owing  under  this Lease with any
payment of Monthly Rent and  additional  rent  arising  under the Section of the
Original Lease entitled  "RENTAL  ESCALATIONS  FOR INCREASES IN EXPENSES" of the
Original  Lease  made by Lessee  for those rent  obligations  arising  under the
Original  Lease from and after January 1, 1997.  Lessee shall also pay to Lessor
with the payment of Monthly Rent such payments of  additional  rent provided for
in the Section of the Lease entitled,  "OPERATING EXPENSES,  OPERATING COSTS AND
REAL ESTATE TAXES."

         (E) If Rent  Commencement  Date 1, and therefore the  obligation  under
this Lease to pay Monthly  Rent 1, begins on a day other than the first day of a
calendar  month,  then  Monthly Rent I from such date until the first day of the
following calendar month shall be prorated at the rate of one-thirtieth (1/30th)
of  Monthly  Rent I for  each day of that  month  from  and  including  the Rent
Commencement   Date  1,  payable  in  advance,   as  specified  above.  If  Rent
Commencement Date 2, and therefore the obligation under the Lease to pay Monthly
Rent 2,  begins on a day other  than the first  day of a  calendar  month,  then
Monthly  Rent 2 from such date  until  the first day of the  following  calendar
month shall be prorated at the rate of one-thirtieth  (1/30th) of Monthly Rent 2
for each day of that  month from and  including  the Rent  Commencement  Date 2,
payable in advance, as specified above.

         (F) If Lessor was unable to deliver the Additional Premises in Delivery
Condition  by May 31,  1997,  and the  Commencement  Date 2 is a date after such
date,  then provided  Lessee has not exercised any right to cancel this Lease as
provided in the Section of this Lease entitled  "TERM," Lessee shall be entitled
to and Lessor  shall  recognize  as a credit to Monthly  Rent 2 (as  hereinafter
defined)  applicable  after  Rent  Commencement  Date 2 an  amount  equal to the
product of (i) the amount of Monthly Rent 2 per calendar  day  (calculated  on a
thirty (30) day month), times (b) the number of calendar days after May 31, 1997
that Lessor is delayed in the delivery of the  Additional  Premises to Lessee in
the Delivery Condition.

         (G) (i) In the event that Lessor has not completed the Fire/Life Safety
Modifications or alternatively  reached  agreement with the District of Columbia
binding upon Lessor  concerning  undertaking the Fire/Life Safety  Modifications
and such failure (a) results in the District of Columbia causing Lessee to cease
use of all or a portion of the Original  Premises for Lessee's  regular business
operations at some point in time after  Commencement Date 1, (b) delays Lessee's
right to lawfully occupy the Additional  Premises for Lessee's  regular business
operations,  or (c) both, then for so long as Lessee is prevented from occupying
some or all of the Demised  Premises for it regular business  operations  Lessee
will be  entitled  to an  abatement  of Monthly  Rent,  but only as  hereinafter
provided in this Subsection.

                  (ii) (a) Where Lessee is notified by the  Reviewing  Officials
that the  issuance of Permits  will be delayed  solely due to the absence of, or
alternatively  the failure of Lessor to agree with the District of Columbia upon
the  completion  of, the Fire/Life  Safety  Modifications  and such delay in the
issuance of Permits  continues  for a period of more than  thirty (30)  calendar
days,  (b)  where  Lessee  is  delayed  in  the  installation,   fabrication  or
construction of Initial  Alterations for more than thirty (30) calendar days and
such delay is due solely to the absence of, or  alternatively  to the failure of
Lessor  to agree  with the  District  of  Columbia  upon the  completion  of the
Fire/Life  Safety  Modifications,  or (c) where Lessee's lawful occupancy of the
Additional  Premises is delayed for more than  thirty (30)  calendar  days after
substantial  completion of Initial  Alterations  and such delay is due solely to
the  absence  of, or  alternatively  the  failure  of  Lessor to agree  with the
District of Columbia upon the completion of, the Fire/Life Safety Modifications,
and in any case Lessee has- not  cancelled  this Lease as provided in Subsection
(E) of the Section of this Lease  entitled  "TERM",  Lessee shall be entitled an
abatement  of Monthly Rent 2. The amount of abatement of Monthly Rent 2 shall be
equal-to  one  thirtieth  (1/30th) of the amount of Monthly  Rent 2 for each day
that Lessee is so delayed after the expiration of the applicable thirty (30) day
period from  occupying  the  Additional  Demised  Premises for Lessee's  regular
business  operations.  Any abatement of Monthly Rent 2 herein  provided shall be
applied to Lessee's  obligation  for Monthly  Rent 2 otherwise  arising from and
after the Rent  Commencement  Date 2. Any accrual of abated Monthly Rent 2 under
this  Subsection  shall  cease as of the  earlier  of (x) the date  that  Lessee
obtains the Permits for Initial  Alterations,  (y) the date that Lessor delivers
to Lessee the last of any required  Completion  Notices  specified in Subsection
(D) of the Section of this Lease  entitled  "DEMISED  PREMISES," or (z) the date
Lessee  completes  installation  of interim fire and life safety  devices  which
permit Lessee to lawfully occupy the Demised Premises.

(iii)Where Lessee's lawful  occupancy of the Original  Premises or a substantial
     portion thereof for Lessee's  regular  business  operations is prevented by
     order  of an  Inspecting  Official  from  and  after  the  commencement  of
     construction of Initial Alterations,  and such interruption in occupancy is
     solely due to the  absence  of, or  alternatively  the failure of Lessor to
     agree with the District of Columbia upon the  completion  of, the Fire/Life
     Safety  Modifications,  then  Monthly  Rent 1 shall be abated from the date
     that Lessee's occupancy of the Original Premises or the substantial portion
     thereof for its regular business  operations is required by the District of
     Columbia to cease.  The amount of Monthly  Rent I to be abated from time to
     time and day for day shall be equal to one-thirtieth  (1/30th) of an amount
     equal to the product of Monthly  Rent 1 times a fraction  the  numerator or
     which is the area of the Original  Premises that Lessee cannot  lawfully be
     occupied  on that day for  Lessee's  regular  business  operations  and the
     denominator of which is the area of the Original Premises. Any abatement of
     Monthly Rent I under this  Subsection  shall cease as of the earlier of (a)
     the date that Lessee  receives notice from the District of Columbia that it
     may lawfully  re-occupy the Original  Premises or the portion thereof,  (b)
     the date that Lessor delivers to Lessee the last of any required Completion
     Notices  specified in Subsection  (D) of the Section of this Lease entitled
     "DEMISED PREMISES",  (c) the date Lessee completes  installation of interim
     fire and life safety  devices  which permit  Lessee to lawfully  occupy the

For  the purposes of this Lease the phrase  "substantial  portion" shall mean in
     excess  of  twenty  percent  (20%)  of the  rentable  area of the  Original
     Premises.  As and to the extent that lawful  occupancy  of less than all of
     the  Original  Premises is  involved  and there is a  disagreement  between
     Lessor  and  Lessee as to whether a  substantial  portion  of the  Original
     Premises is effected,  and the determination by the District of Columbia is
     not  dispositive  on the  matter,  then  Lessor and Lessee  agree that such
     determination shall be made by Lessee's architect,  applying  -professional
     standards to its evaluation of what portion of the Original Premises cannot
     be  lawfully  used for  Lessee's  regular  business  operations  due to the
     District of Columbia's determination.,

sentence  shall be calculated  independently  without  reference to one another.
Lessee shall commence to make its first  Estimated  Payments on the first day of

Operating Expenses, Operating Costs and Real Estate Taxes for each calendar year
shall be those actually incurred,  provided,  however,  that if the Building was
not at least ninety-five  percent (95%) occupied during the entire calendar year
on a monthly weighted average basis, then those components of Operating Expenses
and of  Operating  Costs  identified  below as Variable le  Components  shall be
adjusted to project  those  components  of  Operating  Expenses and of Operating
Costs  would  have been if the  Building  had been  ninety-five  percent  (95 %)
occupied on a monthly  weighted  average basis during that entire calendar year.
The Variable Components of Operating Costs shall be:

                  (i)      the costs related to  consumption  of  electricity to
                           the  extent  standard  levels  of power are not to be
                           consumed in unoccupied tenant areas of the Building;

                  (ii)     the costs of char  services  to the  extent  standard
                           levels of such  services  are not being  provided  to
                           unoccupied   office  areas  and  provided   that  the
                           cleaning  contract  for the  Building  provides for a
                           cost  reduction in direct  proportion to the occupied
                           office areas of the Building being serviced;

                  (iii)    the costs related to consumption of water services to
                           the extent such  utility is not being  consumed  with
                           respect to the unoccupied areas of the Building; and,

                  (iv)     the costs related to consumption of sewer services to
                           the extent such  utility is not being  consumed  with
                           respect to the unoccupied areas of the Building.

The Variable  Component of Operating  Expenses  shall be management  fees to the
extent that rental income is not being received.  by Lessor on unoccupied  areas
of the Building.

         (L) Lessor shall submit to Lessee a statement  setting  forth  Lessor's
determination  of (i) any increases in Operating  Expenses,  Operating Costs and
Real Estate Taxes over the Operating  Expenses,  Operating Costs and Real Estate
Taxes, respectively for the Base Year; (ii) Lessee's proportionate share of such
increases;  and (iii)  Lessee's  net  obligation  for such  Operating  Expenses,
Operating  Costs and Real Estate  Taxes for the  calendar  year  ("Lessee's  Net
Obligation")  which  reflects  the credit of  Lessee's  Estimated  Payments  for
Estimated  Operating  Expenses,  Estimated  Operating  Costs and Estimated  Real
Estate  Taxes  during  the  prior  calendar  year.  In  computing  Lessee's  Net
Obligation,  increases in Operating  Expenses and Operating Costs, and increases
in Real Estate Taxes shall be computed  independently  without  reference to one
another. Within thirty (30) days after the delivery of such statement (including
any statement  delivered  after the  expiration or earlier  termination  of this
Lease),  Lessee  shall  pay  Lessor  the full  stated  amount  of  Lessee's  Net
Obligation.  If the aggregate amount of Lessee's  Estimated  Payments during the
prior calendar year exceeds Lessee's proportionate share of (i) the increases in
Operating  Expenses,  (ii) the  increases  in.  Operating  Costs,  and (iii) the
increases  in Real Estate  Taxes,  the  excess,  at  Lessor's  option,  shall be
refunded to Lessee or credited to Lessee's next arising payment of Monthly Rent,
until such excess is fully  refunded to Lessee or credited to Lessee as provided
above.

         (M) Lessee,  and/or a reputable agent of Lessee retained by Lessee may,
at Lessee's expense,  at reasonable times,  audit Lessor's books and records for
the Building  relating to Lessor's  determination of any increase or decrease in
the Operating  Expenses,  Operating Costs and Real Estate Taxes for the calendar
year for which Lessor's current determination is being made. In conjunction with
that audit of the current  year's  determination,  Lessee or its agent may audit
the two (2) immediately  preceding  calendar years. Any audit must be undertaken
and completed no later than twelve (12) full calendar months after the date that
Lessee receives notice of Lessor's current  determination.  Notwithstanding  the
foregoing Lessee may audit, except for the Base Year, a calendar year only once;
Lessee may audit the Base Year twice  provided  that all audits of the Base Year
must be completed prior to December 31, 2002.

         (N) Lessor shall compute the Operating  Expenses,  Operating  Costs and
Real Estate Taxes on the accrual basis. Any refund of Real Estate Taxes received
by Lessor  with  respect  to any period  during the term of this Lease  shall be
credited  to the year to which the refund  accrued  and not to the year in which
any such refund is received by Lessor;  thereafter the Lessee's  obligations for
additional rent for Real Estate Taxes for that year shall be recalculated  and a
refund made or credit given to Lessee,  provided that if a refund of Real Estate
Taxes  received is applicable to the Base Year,  then  Lessee's  obligation  for
additional rent pertinent to Real Estate Taxes for each year after the Base Year
shall be recalculated and any additional rent obligation arising therefrom shall
be noticed to Lessee and shall  become due and payable by Lessee  within  thirty
(30) days of receipt of Lessor's notice. Such additional amounts shall be deemed
to be for the purposes of this Lease additional rent.

Section of the Lease, subject however to any adjustment as may occur by Lessee's
exercise of its rights to lease other spaces of the Building as provided in this
Lease.

         (B)  Notwithstanding  the  forgoing,  and in lieu of any  adjustment to
Monthly  Rent on  January  1,  2002  pursuant  to  Subsection  (A) above of this
Section,  Monthly  Rent as of January 1, 2002 shall be equal to Monthly  Rent in
effect for the calendar  month of December  2001  adjusted  and  increased by an
amount  equal to  one-twelfth  (1/12th) of the product of (i) the then  rentable
area of the  Demised  Premises,  times  (ii)  Two and  00/ 1 00ths  Dollars  per
rentable square foot of the Demised Premises., This Monthly Rent, subject to any

         (A) In  connection  with  Lessee's  leasing  of the  Original  Premises
pursuant to this Lease,  Lessor guarantees that it shall assure the availability
to Lessee of twenty-two  (22) parking  contracts for the parking  garage serving
the Building.  In connection with Lessee's  leasing of the Additional  Premises,
Lessor  guarantees  that it  shall  assure  the  availability  to  Lessee  of an
allocation of up to five (5) additional  parking contracts in the parking garage
serving the Building.  All of said allocation of said parking contracts shall be
for the use by  Lessee  and its  employees.  The  rights  to  parking  contracts
allocated to the Original  Premises  shall be deemed  vested by the execution of
this Lease by Lessor and Lessee. To vest the rights to parking contracts in that
parking garage related to the Additional Premises,  Lessee must notify Lessor in
writing of the number of parking  contracts  it  desires,  and Lessee must enter
into said  contracts  with the parking  garage  operator or manager within sixty
(60)  days  following  the  Rent  Commencement  Date 2 with  regard  to  parking
contracts  related  to  the  Additional  Premises.   Lessee  shall  be  directly
responsible to the parking  garage  operator for the payment of any and all fees
or  charges  thereunder.  Lessor  shall be under  no  obligation  to pay for any
parking  contracts.  These  parking  contracts  shall contain the same terms and
conditions as are usually contained in such contracts with other monthly parking
customers  of the parking  garage  operator,  and the monthly rate to be paid by
Lessee shall be the  prevailing  monthly rate charged to other  monthly  parking
customers,  said rate to increase and decrease as the prevailing monthly parking
rate for other monthly  parking  customers  increases and decreases from time to
time.

In the event Lessee fails to execute with the parking garage operator or manager
all or a portion of the monthly  parking  contracts  allocated to the Additional
Premises within applicable sixty (60) day period,  or subsequently  relinquishes
in any manner after vesting any parking contract (whether arising with regard to
the Original Premises,  the Additional Premises or any other space leased in the
Building by Lessee pursuant to this Lease),  Lessor shall be under no obligation
to seek restoration of the  relinquished  contracts or waive Lessee's failure to
execute said contracts.

         (B) As  and  when  Lessee  leases  additional  spaces  in the  Building
pursuant to this Lease,  Lessee  shall be entitled to and Lessor shall have made
available to Lessee one (1) additional  parking  contract for the parking spaces
serving the Building for each  seventeen  hundred fifty (1750)  rentable  square
feet of  additional  rentable  area so leased by Lessee.  Lessee must (i) notify
Lessor in writing within sixty (60) days following the commencement date of this
Lease  with  regard to such  space of its  desire  for all or a portion  of such
additional  parking  contracts,  and (ii)  enter  into said  number  of  parking
contracts with the parking garage operator or manager within such sixty (60) day
period.  All other  provisions  of this Section  shall be applicable to Lessee's
rights  to  such  contracts  and  Lessor's  obligation  to have  such  contracts
delivered to Lessee.


8.       OPTION TO TERMINATE

         (A) Lessor  grants to Lessee one (1)  option to  terminate  the term of
this  Lease  with  regard  to  the  entire  Demised  Premises  only,  with  such
termination  to  be  effective  as  of  11:59  p.m.,   December  31,  2003  (the
"Termination  Date"),  provided that Lessee  exercises  such option as set forth
below,  and further  provided that Lessee is not in default under this Lease (i)
due to its failure to timely make any payment of Monthly Rent, of any additional
rent arising  under and pursuant to the  provisions of the Section of this Lease
entitled "OPERATING  EXPENSES,  OPERATING COSTS AND REAL ESTATE TAXES", or both,
in any case after  notice of such  failure has been given to Lessee by Lessor as
hereinafter  provided  in this Lease and Lessee  has not  timely  exercised  its
opportunity to cure such failure as so provided, (ii) due to Lessee's bankruptcy
or insolvency,  (iii) due to Lessee's  assignment of this Lease in contravention
of the  provisions  of the  Section  of  this  Lease  entitled  "ASSIGNMENT  AND
SUBLETTING",  and  Lessee's  failure to timely cure or correct such matter after
notice has been given  thereof by Lessor,  (iv) due to  Lessee's  subleasing  of
areas within the Demised Premises to any party,  other than a Permitted Licensee
(as hereinafter  defined),  in contravention of the provisions of the Section of
this Lease entitled "ASSIGNMENT AND SUBLETTING",  and Lessee's failure to timely
cure or correct such matter after  notice has been given  thereof by Lessor,  or
(v) due to Lessee's having  undertaken  Alterations of the Demised Premises from
and after January 1, 2001 in  contravention  of the provisions of the Section of
this Lease entitled "ALTERATIONS",  the value of which Alterations as reasonably
estimated by Lessor are in excess  Seventy Five Thousand and 00/ 100ths  Dollars
($75,000.00)  and  Lessee's  failure to timely cure or correct such matter after
notice has been given  thereof by Lessor  (collectively  items (i)  through  (v)
being  hereinafter  referred  to as a  "Material  Default"),  either on the date
Lessee  notifies  Lessor of its intent to  exercise  this  option or at any time
thereafter up to and including the  Termination  Date.  Lessee may exercise this
option only by serving on Lessor  written  notice of its intent to exercise this
option no later than 5:00 p.m. on June 30, 2002.

         (B) As  consideration  for Lessor  granting  to Lessee  this  option to
terminate  the term of this Lease with regard to the  Original  Premises and the
Additional  Premises.,  and provided  that Lessee  subsequently  exercises  such
option to  terminate,  Lessee shall pay to Lessor on or before  thirty (30) days
prior to the Termination Date a termination fee in an amount equal to the sum of
(i) Four Hundred Forty-five Thousand and 00/100ths Dollars  ($445,000.00) (being
equal to approximately  thirty percent (30%) of (a) the unamortized value of the
Allowance  using a straight line  amortization  schedule and (b) the unamortized
value of leasing commissions incurred and paid by Lessor to Lessee's real estate
broker in  conjunction  with the  making of this Lease  (using a  straight  line
amortization  schedule  based upon a lease term of ten (10) calendar  years) and
(ii) the  product  of (a) three  (3)  times  (b) the sum of the then  applicable
Monthly Rent for the Original Premises and the Additional Premises, and Lessee's
then current  obligation for Estimated  Payments  (collectively such amounts due
and owing to Lessor under (i) and (ii) above being  defined in the  aggregate as
the "Termination Payment"). The Termination Payment shall be delivered to Lessor
in immediately available funds, United States of America currency.

                                    (C) If Lessee (i) is in Material  Default of
                  this Lease,  (ii) fails to timely and properly  give to Lessor
                  notice of Lessee's  exercise of this  option to  terminate  as
                  hereinabove   provided,   or  (iii)   fails  to  deliver   the
                  Termination  Payment  to  Lessor  no later  than  thirty  (30)
                  calendar days prior to the Termination Date, then Lessee shall
                  be deemed to have waived its rights to exercise this option to
                  terminate  and the  Lease  shall  continue  in full  force and
                  effect.  Lessee shall have no further  option to terminate the
                  term of this Lease before the expiration of its natural term.


         (D) If Lessee  timely,  properly and fully complies with all provisions
of this  Section of the Lease,  then the term of this Lease  shall  expire as of
11:59 p.m. on the  Termination  Date, as if the Lease had  naturally  expired on
such date,  with each party  being  equally  released  and  discharged  from any
obligations to observe the terms and conditions if this Lease accruing after the
Termination  Date.  Lessee shall  continue to be liable for all rent,  including
Monthly Rent and  additional  rent accrued,  including  additional  rent arising
through  application  of the  provisions  of the Section of this Lease  entitled
"OPERATING  EXPENSES,  OPERATING  COSTS AND REAL  ESTATE  TAXES",  and  accruing
through the  Termination  Date.  Lessee shall deliver  possession of the Demised
Premises to Lessor as of the  Termination  Date free of any existing  tenancies,
subtenancies and occupancies,  free and clear of personal property of Lessee and
such  others and in broom  clean  condition,  and with no claims (or  threats of
claims) of liens of any kind.

(E)  The Termination  Penalty  provided for in Section (B) of this Section shall
     apply only with regard to the  termination of this Lease with regard to the
     Original Premises and the Additional Premises.  If Lessee shall have leased
     any spaces in the Building  pursuant to the  provisions of this Lease,  and
     subsequently  gives  its  notice  of  termination  of this  Lease to Lessor
     pursuant to this Section,  Lessee shall be obligated to pay to Lessor, with
     the  Termination  Penalty,  as  additional  consideration  related  to  the
     termination of this Lease with.  regard to such  additional  space(s).  The
     consideration  for  termination  of this Lease with  regard to such  spaces
     shall be  determined  at the time Lessor and Lessee reach  agreement on the
     terms under which  Lessee shall lease such space from Lessor and the amount
     of such  termination  penalty with regard to such space shall be recited in
     any addendum to this Lease  reflecting  such  transaction.  The termination
     penalty fixed for and  applicable to any space so leased by Lessee shall be
     the  sum of (i) the  unamortized  value  of any  tenant  concessions  (e.g.
     buildout allowances, rent abatement, etc.) granted to Lessee in conjunction
     with  the  leasing  of such  space  (using  a  straight  line  amortization
     schedule),  (h) the unamortized value of any leasing  commissions  incurred
     and paid by Lessor in conjunction  with the leasing of such space to Lessee
     (using a  straight  line  amortization  schedule  based  upon a lease  term
     equivalent  to the  remainder of the term of this Lease with regard to such
     space, without consideration of any option to extend available), and

(iii) the  product  of three (3) times  the  applicable  rent for such  space or
spaces (e.g. Expansion Space On Monthly Rent (as hereinafter defined), etc.).


9.       OPTION TO EXTEND

         (A)  Lessor  grants to Lessee  one (1) option to extend the term of the
Lease for a period of five (5) years (the "Extension  Period"),  provided Lessee
exercises  such option as set forth below,  and provided  further that Lessee is
not in Material  Default  under this Lease  either on the date  Lessee  notifies
Lessor of its intent to exercise this option or at any time thereafter up to and
including  the date upon which the Extension  Period is to commence.  Lessee may
exercise this option to extend only by serving on Lessor  written  notice of its
intent to exercise  this option no later than June 30,  2005,  nor earlier  than
January 1, 2005.

         (B) Within  thirty  (30) days after the date Lessor  receives  Lessee's
notice,  if such notice is timely and properly  given,  Lessor shall  deliver to
Lessee Lessor's  determination of what Monthly Rent under the Lease should be as
of the commencement of the Extension Period as well as any escalation formula of
Monthly Rent applicable during the Extension Period;  Lessor's  statement of the
initial Monthly Rent shall be based upon Lessor's  reasonable  determination  of
what the Net Effective Market Rental Rate (as hereinafter defined) will be as of
the  commencement of the Extension  Period as well as its  determination  of the
then applicable Market Escalator (as hereinafter  defined).  For sixty (60) days
following the date Lessor delivers its  determination of these business terms to
Lessee,  Lessor and Lessee will attempt in good faith to reach mutual  agreement
on the these business terms under which Lessor is willing to lease to Lessee and
Lessee is willing to lease from Lessor the Demised  Premises  for the  Extension
Period.  The initial  Monthly Rent for the Extension  Period shall be based upon
one  hundred  percent  (100%) of the Net  Effective  Market  Rental Rate for the
Demised Premises as of the commencement of the Extension Period.

         The  Monthly  Rent during the  Extension  Period  shall  continue to be
subject to annual adjustment and escalation,  but such adjustment and escalation
shall be based upon the then  prevailing  mechanism  for  effectuating  periodic
escalation  of base rent in the market  place for office  leases in the  central
business  district  of  the  District  of  Columbia  (the  "Market  Escalator").
Additional rent for Operating Expenses, Operating Costs and Real Estate Taxes as
set forth in the Section of this Lease entitled,  "OPERATING EXPENSES, OPERATING
COSTS AND REAL ESTATE TAXES,  " shall  continue  uninterrupted  from the initial
term of the I-ease through the Extension  Period,  except that the Base Year (as
such term is defined in that Section) shall become calendar year 2007. All other
terms and  provisions  of the Lease shall remain in full force and effect during
the Extension Period,  except that Lessee shall have no further option to extend
the term of the Lease.

         (C) In the event  Lessor and Lessee  are  unable to agree  within  said
sixty (60) day period upon the Net Effective  Market Rental Rate for the Demised
Premises as of the  commencement  of the Extension  Period in order to determine
the initial  Monthly Rent for the Extension  Period or upon the then  prevailing
Market  Escalator,  then  the  Net  Effective  Market  Rental  Rate  as  of  the
commencement of the Extension Period upon which the initial Monthly Rent for the
Extension  Period  will  be  based,  the  Market  Escalator,  or both  shall  be
determined  by a board of three (3)  licensed  real estate  brokers.  Lessor and
Lessee shall each appoint one (1) broker  within ten (10) days after  expiration
of the sixty (60) day period,  or sooner if  mutually  agreed  upon.  The two so
appointed  shall  select a third  within  fifteen (15) days after they both have
been  appointed.  Each broker on said board shall be licensed in the District of
Columbia  as a Real  Estate  Broker,  specializing  in the  field of  commercial
leasing  in the  central  business  district  having no less than ten (10) years
experience in such field,  and recognized as ethical and reputable within his or
her field.  Each  broker,  within  fifteen  (15) days after the third  broker is
selected,  shall submit his or her  determination  of the Net  Effective  Market
Rental Rate as of the  commencement  of the  Extension  Period.  -Net  Effective
Market  Rental  Rate  shall  be  the  mean  of  the  two  closest   rental  rate
determinations,  and the initial Monthly Rent for the Extension  Period shall be
based upon the Net  Effective  Market Rental Rate. If the three broker method is
used to determine the Market Escalator, then the method identified by a majority
of the brokers as the prevailing method of effectuating  escalation of base rent
in the market  place  shall  become the Market  Escalator  during the  Extension
Period.

         "Net Effective  Market Rental Rate" shall mean the net effective annual
base rental rate,  taking into account  delivery of full building  services by a
landlord,  that would be received by a landlord  renting space of quality,  size
and  location  comparable  to the Demised  Premises in a building of  comparable
size,  age and quality  (taking into  account any  significant  renovation)  and
location to the Building in the central  business  district of Washington,  D.C.
for a comparable  transaction which is to be effective on or about the effective
date of the  transaction  in question  between  Lessor and  Lessee,  adjusted to
reflect that the  provisions  of the Section of the Lease  entitled,  "OPERATING
EXPENSES,  OPERATING COSTS AND REAL ESTATE TAXES" shall remain in full force and
effect (except for any change in the identification of the Base Year as and when
specified by the applicable  Section of this Lease), and that Monthly Rent shall
be subject to annual  adjustment  and  escalation  by a Market  Escalator.  "Net
effective  annual base rental rate" shall mean the stated or quoted  annual base
rental rate, based upon full service delivery by a landlord, adjusted to reflect
and include,  on a present value basis,  the value of landlord  costs,  landlord
savings and tenant concessions,  such as but not limited to, rent abatement, and
cash  allowances  or credits  for  tenant  fitout or  refurbishment,  then being
generally  experienced or offered in the  marketplace by landlords of comparable
buildings for comparable space for comparable lease transactions.

         Lessor and Lessee  shall each pay the fee of the broker  selected by it
and they shall share the payment of the fee of the third broker.

         (D) Lessor shall have  prepared an addendum  setting  forth the term of
the Extension  Period,  the initial Monthly Rent and other appropriate terms and
conditions  upon which the Demised  Premises will be leased during the Extension
Period. Lessor and Lessee agree in good faith to proceed to diligently negotiate
and execute such addendum with intent of having such addendum executed by Lessor
and Lessee  within  sixty (60) days after the date Lessor and Lessee  agree upon
the business terms for the extension of the term of this Lease, or alternatively
if  applicable  the date that the brokers  present their  determinations  of Net
Effective Market Rental Rate for the Extension Period.

         (E) This  Section  of the Lease  shall  become  null and void and of no
force and effect if Lessee  assigns this Lease or has  subleased at any one time
in excess of thirty  percent  (30%) of the area of the Demised  Premises as then
leased by Lessee,  to any party other than to a qualified  party  identified  in
Subsection  (D)  of  the  Section  of  this  Lease  entitled   "ASSIGNMENT   AND
SUBLETTING".

10.      OPTIONS TO EXPAND

         (A)  Lessor  grants to Lessee two (2)  options  to expand  the  Demised
Premises  during the term of this Lease.  The first option to expand the Demised
Premises (the "First Expansion  Option") shall apply at Lessee's election either
to (i) the premises  currently leased by Phillips  Petroleum Company  containing
approximately  8,548 square feet of rentable  area on the seventh (7th) floor of
the Building  (the "Minimum  Area"),  or (ii) the Minimum Area plus the premises
currently leased to Fiat Washington,  Inc. containing approximately 3,347 square
feet of rentable area  contiguous to the Minimum Area on the seventh (7th) floor
of the Building (the Minimum Area and the additional  premises being referred to
as the  "Expanded  Area").  Either  the  Minimum  Area or the  Expanded  Area as
selected by Lessee  shall  hereinafter  be referred to as the  "Expansion  Space
One".  The  Minimum  Area and the  Expanded  Area are  outlined  on Exhibit  A-2
attached hereto and made a part hereof.  The second option to expand the Demised
Premises  (the "Second  Expansion  Option")  shall apply to space on the seventh
(7th)  floor of the  Building,  having a rentable  area of  approximately  2,399
square feet (said area being  hereinafter  referred to as the  "Expansion  Space
Two").  Expansion Space Two is roughly  indicated on Exhibit A-3 attached hereto
and made a part hereof.  Expansion  Space One and the  Expansion  Space Two, are
hereinafter  sometimes,  singularly or  collectively,  referred to as "Expansion
Space. " Lessee's entitlement to each option to expand shall be conditioned upon
Lessee  exercising the applicable option to expand as set forth below. If Lessee
shall be in Material Default under this Lease either on the date Lessee notifies
Lessor of its intent to exercise the applicable  option to expand or at any time
thereafter up to and including the  commencement  date of the term of this Lease
with respect to the applicable  Expansion  Space,  then the option to expand the
Demised Premises with regard to the applicable Expansion Space shall become null
and void and of no further force and effect.

         (B)  (i)  Lessee  may  exercise  the  First  Expansion  Option  only by
delivering  written notice to Lessor,  not later than April 1, 1998, nor earlier
than October 1, 1997, specifying (i) its exercise of the First Expansion Option,
and (ii)  stating  whether the Minimum  Area or the  Expanded  Area is to be the
space defined as Expansion Space One. If Lessee timely and properly gives notice
of its exercise of this First Expansion  Option,  the commencement  date of this
Lease with regard to the Expansion  Space One, and the date Lessor shall deliver
possession  of the  Expansion  Space One to Lessee,  shall be April 1, 1999 (the
"Expansion Space One Lease Commencement Date"). In the event Lessor is unable to
deliver  possession  of the  Expansion  Space One to  Lessee  by April 1,  1999,
Lessor, its agents and employees, shall not be liable or (i) Lessee shall accept
the applicable Expansion Space, as part of the Demised Premises, in its then "as
is" condition,  existing on the date that possession of the applicable Expansion
Space is  delivered  to Lessee by  Lessor,  without  Lessor  being  required  to
undertake any demolition,  removals,  alternations,  improvements,  decorations,
repairs or modifications of that Expansion Space,  except that Lessor shall take
such steps as  reasonably  necessary to ensure that building  standard  services
specified in the Section of this Lease  entitled  "SERVICES AND  UTILITIES"  are
readily  available to that Expansion Space, that that Expansion Space is fit out
to a condition no less than building standard  condition as specified in Exhibit
B to this Lease,  and that base  building  fire and life  safety  systems of the
Building  are  sufficiently  in  compliance  with  applicable  local  codes  and
ordinances  such that Lessee may obtain a  certificate  of occupancy  for use of
that Expansion Space for Lessee's  business  purposes and that Lessee may obtain
all necessary  permits and licenses to permit Lessee to make  Alterations to the
Expansion  Space,  which  Alterations by their nature fall generally  within the
scope and kind of building standard improvements identified in Exhibit B to this
Lease.

                  (ii) The term of the  I-ease  with  respect  to the  Expansion
Space One shall commence on the Expansion Space One Lease Commencement Date, and
said term  shall be  coterminous  with the  initial  term of this  Lease and any
extension  thereof duly exercised by Lessee;  the term of the Lease with respect
to the  Expansion  Space Two shall  commence  on the  Expansion  Space Two Lease
Commencement  Date,  and said term  shall be  coterminous  with the term of this
Lease as duly extended by Lessee.

                  (iii) Lessee shall pay to Lessor,  as the initial monthly rent
for the Expansion Space One (hereinafter "Expansion Space One Monthly Rent"), an
amount equal to one-twelfth (1/12th) of the product of the number of square feet
of rentable  area  attributable  to the  Expansion  Space One  multiplied by one
hundred  percent (100%) of the Net Effective  Market Rental Rate projected to be
in effect as of the  Expansion  Space One  Commencement  Date and further to pay
Expansion  Space One Monthly Rent to Lessor with Monthly Rent;  Lessee shall pay
to Lessor,  as the initial  monthly rent for the Expansion Space Two ("Expansion
Space Two  Monthly  Rent"),  an amount  equal to  one-twelfth  (1 / l2th) of the
product  of the  number of square  feet of  rentable  area  attributable  to the
Expansion  Space  Two,  multiplied  by one  hundred  percent  (100%)  of the Net
Effective Market Rental Rate projected to be in effect as of the Expansion Space
Two  Commencement  Date and further to pay  Expansion  Space Two Monthly Rent to
Lessor with Monthly Rent. If Lessor and Lessee cannot reach agreement on the Net
Effective  Market  Rental  Rate  within  sixty (60) days  after the date  Lessor
receives  Lessee's  notice of  election  to exercise  the  applicable  Expansion
Option,  Net Effective  Market Rental Rate for the  applicable  Expansion  Space
shall be determined in accordance with the procedure set forth in Subsection (C)
of the Section of this Lease entitled  "OPTION TO EXTEND." Net Effective  Market
Rental  Rate  shall  take  into  account  that (i) any such  Monthly  Rent of an
Expansion Space shall be subject to periodic  escalation during the term of this
Lease as provided in Subsection (C)(vii) below of this Section,  and (ii) Lessee
shall be paying to Lessor with regard to such Expansion  Space  additional  rent
arising under the provisions of the Section of this I-ease  entitled  "OPERATING
EXPENSES,  OPERATING  COSTS AND REAL ESTATE  TAXES" and that the  calendar  year
fixed as the Base Year for the calculations under that Section of the Lease with
regard to the applicable Expansion Space shall be the calendar year in which the
appropriate  Commencement Date of this Lease with regard to that Expansion Space
occurs.

                  (iv) Lessee shall commence to pay Expansion  Space One Monthly
Rent, in advance, from and after the Expansion Space One Commencement Date.

                  (v) Lessee shall  commence to pay Expansion  Space Two Monthly
Rent, in advance, from and after the Expansion Space Two Commencement Date.

                  (vi)  Lessee  shall  commence  to  pay,  with  regard  to  the
applicable Expansion Space,  additional rent arising under the provisions of the
Section of this Lease entitled  "OPERATING  EXPENSES,  OPERATING  COSTS AND REAL
ESTATE TAXES" as of the applicable  Expansion Space  Commencement  Date,  except
that the  calendar  year fixed as the Base Year for the  purposes  of making the
calculations  under  that  Section  shall  be,  with  regard  to the  applicable
Expansion  Space, the calendar year in which the appropriate  Commencement  Date
fixed under the  applicable  provisions  of  Subsection  (B) above  occurs.  The
percentages of Lessee's  proportionate  shares of Operating Expenses,  Operating
Costs and Real Estate Taxes with regard to the applicable  Expansion Space shall
be determined by comparing the applicable  rentable area of the Expansion  Space
in question to the stated  rentable area of the office spaces of the Building or
the stated  rentable  area of the office and retail  spaces of the  Building  as
given in that Section of this Lease.

                  (vii) During the initial term of this Lease, each of Expansion
Space One Monthly Rent and Expansion  Space Two Monthly Rent as initially  fixed
shall be subject to adjustment  and increase as and when Monthly Rent is subject
to  adjustment  pursuant  to the  provisions  of Section of this Lease  entitled
"ANNUAL  ESCALATION OF MONTHLY  RENT," and in accordance  with the formula fixed
therein for increase and  escalation  of Monthly  Rent,  provided  that any such
increase in either  Expansion  Space One  Monthly  Rent or  Expansion  Space Two
Monthly  Rent shall be abated  during the period  from the  Expansion  Space One
Commencement  Date or the Expansion Space Two Commencement  Date, as applicable,
through the last day of the  calendar  month that is twelve  (12) full  calendar
months following the applicable  Commencement Date. During the Extension Period,
each of Expansion  Space One Monthly Rent and  Expansion  Space Two Monthly Rent
shall be subject to  adjustment  and increase by the  prevailing  mechanism  for
effectuating an escalation of Monthly Rent agreed upon by Lessor and Lessee,  or
as otherwise  determined  pursuant to the  provisions of  Subsection  (C) of the
Section of this Lease entitled "OPTION TO EXTEND".

                  (viii) All rent  accruing or related to any  Expansion  Space,
including but not limited to Expansion  Space One Monthly Rent,  Expansion Space
Two Monthly Rent and any additional rent attributable thereto,  shall be treated
as part of rent due and owing by Lessee to Lessor under this Lease.

                  (ix) All other terms and  conditions of this Lease shall apply
to each Expansion  Space,  except as the same are  specifically  modified by the
mutual written  agreement of Lessor and Lessee,  with the  applicable  Expansion
Space being deemed to become and be treated as part of the Demised Premises from
and after the applicable Expansion Space Commencement Date.

         (D) If Lessee duly and properly  exercises  the option to terminate the
term of this Lease as provided in the Section of this Lease entitled  "OPTION TO
TERMINATE", then Lessee by giving such notice of its election to terminate shall
be deemed to have waived  thereafter  any  further  rights  under this  Section.
Additionally Lessee shall be obligated to pay to Lessor as consideration for the
right to exercise such right of termination  with regard to any Expansion  Space
leased by Lessee  pursuant to this Section of the Lease,  a termination  payment
calculated as provided in Subsection  (E) of the Section of this Lease  entitled
"OPTION TO  TERMINATE"  Such  termination  payment  shall be due and  payable to
Lessor with the Termination Payment provided for in that Section of this Lease.

         (E) Lessor shall have prepared an addendum  setting forth the terms and
conditions for Lessee's leasing of the applicable  Expansion  Space.  Thereafter
Lessor and Lessee  agree in good faith to proceed to  diligently  negotiate  and
execute such addendum with intent of having such addendum executed by Lessor and
Lessee  within  sixty (60) days after the date Lessor and Lessee  agree upon the
business  terms  for  the  leasing  of  the  applicable   Expansion   Space,  or
alternatively   if   applicable   the  date  that  the  brokers   present  their
determinations  of Net Effective Market Rental Rate applicable to that Expansion
Space.
         (F) As  appropriate,  when Lessor  delivers  possession of an Expansion
Space to Lessee,  Lessor and Lessee shall  execute a document in the form of the
Declaration,  attached  hereto as Exhibit D-2, which shall specify the Expansion
Space One  Commencement  Date,  or a  document  in the form of the  Declaration,
attached  hereto as Exhibit D-3,  which shall  specify the  Expansion  Space Two
Commencement Date.

In each case,  execution of such document shall not be deemed a condition to the
occurrence of the applicable  commencement date of this Lease with regard to the
applicable Expansion Space.

         (G) This  Section  of the Lease  shall  become  null and void and of no
force and effect if Lessee assigns this Lease,  or has subleased at any one time
in excess of thirty  percent  (30%) of the area of the Demised  Premises as then
lease by  Lessee,  to any party  other  than a  qualified  party  identified  in
Subsection  (D)  of  the  Section  of  this.  Lease  entitled   "ASSIGNMENT  AND
SUBLETTING.


11.      FIRST RIGHT TO NEGOTIATE

(A)  Subject to the  conditions  subsequently  set forth in this  Section of the
     Lease,  Lessor  grants to Lessee and Lessee  shall have  during the term of
     this Lease the first right to negotiate to lease  additional  spaces on the
     seventh  (7th)  floor  of the  Building  (each  of such  areas  hereinafter
     referred to as a  "Negotiation  Area"),  provided that (i) Lessee is not in
     Material Default of this Lease either on the date Lessee notifies Lessor of
     its  intent  to  lease  the  applicable  Negotiation  Area or at any time t
     hereafter  up to and  including  the date upon  which the term of the Lease
     with respect to such Negotiation Area is to commence, and (ii) Lessee shall
     not have the benefit of this first right to negotiate (a) within the period
     twenty  four (24)  calendar  months  prior to the  calendar  month in which
     Lessee has the right to terminate the term of this Lease as provided in the
     Section  of this Lease  entitled  "OPTION  TO  TERMINATE"  unless and until
     Lessee waives, in a written document delivered to Lessor, Lessee's right to
     terminate  the term of this  Lease,  (b) within the period  January 1, 2004
     through December 31, 2006,  unless and until Lessee exercises its option to
     extend the term of this Lease  pursuant to the provisions of the Section of
     this Lease entitled  "OPTION TO EXTEND",  and (c) within the period January
     1, 2010 through December 31, 2011.


         (B)  Lessee's  right to  exercise  this first right to  negotiate  with
respect  to  any  specific  Negotiation  Area  granted  to  Lessee  pursuant  to
Subsection  (A) of this Section  shall be  subordinate  to and shall arise -only
upon the  expiration  of (i) the term of the  lease for such  Negotiation  Area,
including any options to extend,  held by the tenant of such Negotiation Area as
of the date first hereinabove stated, (ii) options to expand and first rights to
negotiate for such  Negotiation  Area,  held by any tenant of the Building as of
the date of this Lease first hereinabove stated, including options to extend the
term of any lease  therefor,  and (iii)  options  to expand  applicable  to such
Negotiation  Area,  extend  the  term of any  lease or both  held by any  tenant
leasing spaces on the seventh (7th) floor of the Building after the date of this
Lease first  hereinabove  stated (such  subsequent  tenant of the seventh  (7th)
floor being hereinafter referred to as a "Generic Tenant"), provided that in the
case of item (iii)  either  such space was  offered  to Lessee  pursuant  to the
provisions  of the  Section of this Lease  entitled  "OPTIONS TO EXPAND" or such
space was first  offered  to Lessee  pursuant  to this  Section of the Lease and
Lessee did not elect to  exercise  such  option to  expand,  or did not elect to
exercise  such first right to negotiate,  or if Lessee  elected to exercise such
first  right to  negotiate,  Lessor  and  Lessee  were  unable to agree upon the
business terms under which Lessee would lease the offered  Negotiation Area from
Lessor.  The  failure of Lessee to lease a  Negotiation  Area shall not serve to
permit  Lessor  to grant to any  Generic  Tenant  an option to expand or a first
right to negotiate for such space which would be in conflict with or superior to
Lessee's right to such space under the Section of this Lease  entitled  "OPTIONS
TO EXPAND," including any date of delivery of an Expansion Space as specified in
that Section of this Lease.  Any first right to  negotiate  for any space on the
seventh  (7th)  floor of the  Building  granted to any Generic  Tenant  shall be
inferior to Lessee's rights to such space as Negotiation Area under this Section
of the Lease.  Lessor  advises  Lessee that,  as of the date of this Lease first
hereinabove  stated,  no tenant in the Building as of the date of this Lease has
any rights under paragraphs (i) and (ii) above of this Subsection with regard to
any spaces on the seventh (7th) floor of the Building.

         (C) Provided that all other superior rights for a Negotiation Area have
expired or been  waived,  Lessor  shall  advise  Lessee,  at such time as Lessor
determines  that a Negotiation  Area is or will become  available for leasing to
Lessee, of the availability of such Negotiation Area and the business terms upon
which Lessor is willing to lease that Negotiation Area to Lessee. Lessor may not
give such notice of  availability  more than twelve  (12) full  calendar  months
prior to the scheduled  date of  expiration of any then existing  lease for that
Negotiation  Area.  Within  fifteen (15) business days after receipt of Lessor's
notice,  Lessee shall deliver written notice to Lessor indicating whether Lessee
desires to lease such Negotiation Area or not. If Lessee indicates its desire to
lease an offered Negotiation Area, Lessor and Lessee shall seek to negotiate the
business terms upon which Lessee would lease such  Negotiation Area from Lessor.
The business  terms  offered by Lessor  related to the leasing of a  Negotiation
Area shall provide that (i) the monthly rent  attributable  to such  Negotiation
Area shall be based upon one hundred percent (100%) of the Net Effective  Market
Rental Rate for such  Negotiation  Area  projected  to be  applicable  as of the
commencement  date of this Lease with regard to such Negotiation  Area, such Net
Effective  Market Rental Rate for such  Negotiation  Area being determined based
upon the formula and  procedure  set forth in  Subsection  (C) of the Section of
this Lease entitled  "OPTION TO EXTEND",  substituting  the Negotiation Area for
the  Demised  Premises  as  then  defined,  (ii)  any  such  monthly  rent  of a
Negotiation Area shall be subject to periodic escalation during the term of this
Lease as provided in the Section of this Lease  entitled  "ANNUAL  ESCALATION OF
MONTHLY  RENT",  (iii)  Lessee  shall be paying to  Lessor  with  regard to such
Negotiation  Area additional rent arising under the provisions of the Section of
this Lease entitled "OPERATING EXPENSES,  OPERATING COSTS AND REAL ESTATE TAXES"
and that the  calendar  year fixed as the Base Year for the  calculations  under
that  Section  of the Lease  with  regard to the  Negotiation  Area shall be the
calendar year in which the  commencement  date of this Lease with regard to that
Negotiation  Area occurs,  (iv) Lessee shall accept the  applicable  Negotiation
Area as part of the Demised Premises, in its then "as is" condition, existing on
the date that  possession  of the  Negotiation  Area is  delivered  to Lessee by
Lessor,  without  Lessor being required to undertake any  demolition,  removals,
alternations,  improvements,  decorations,  repairs  or  modifications  of  that
Negotiation  Area,  except  that  Lessor  shall  take  such  steps a  reasonably
necessary to ensure that building 'standard services specified in the Section of
this Lease  entitled  "SERVICES  AND  UTILITIES"  are readily  available to that
Negotiation  Area, that that  Negotiation Area is fit out to a condition no less
than building  standard  condition as specified in Exhibit B to this Lease,  and
that base building fire and life safety systems of the Building are sufficiently
in compliance  with  applicable  local codes and ordinances such that Lessee may
obtain a certificate of occupancy for use of that  Negotiation Area for Lessee's
business  purposes,  and  (v)  the  term  of  this  Lease  with  regard  to such
Negotiation Area shall commence no later than sixty (60) days after the later of
(a) the date that the  Negotiation  Area is  vacated by any  existing  tenant or
tenants,  or (b) the  date  that  agreement  is  reached  on all of the  salient
business terms for the leasing of the  Negotiation  Area by Lessee.  The term of
this  Lease  with  regard to any  Negotiation  Area  leased  by Lessee  shall be
coterminous with the term of this Lease with regard to the Demised Premises.  If
Lessor and  Lessee  are  unable to agree  upon the  amount of the Net  Effective
Market Rental Rate for the leasing of the offered  Negotiation  Area pursuant to
this Lease within  thirty (30) business days after the date of receipt by Lessor
of Lessee's  notice of election to lease a  Negotiation  Area offered by Lessor,
then the  determination of Net Effective Market Rental Rate for that Negotiation
Area shall be made by a three (3) broker panel in accordance  with the procedure
set forth in  Subsection  (C) of the Section of this Lease  entitled  "OPTION TO
EXTEND." Any  determination of Net Effective Market Rental Rate with regard to a
Negotiation   Area  shall  take  into  account  that  Lessee's  leasing  of  the
Negotiation  Area shall be subject to the  provisions  of items (ii) through (v)
above of this Subsection.

      (D) Lessor and Lessee  specifically  recognize that the space described as
Expansion  Space Two became  available for leasing in 1996,  that such space was
offered to Lessee for leasing in  conjunction  with this  transaction as part of
the Demised  Premises,  and that Lessee declined to lease such space.  Lessor is
specifically granted the right to lease such space to a Generic Tenant or to any
existing  tenant of the  Building  provided  that by such  transaction  Lessee's
rights to such space as and when  provided  for under the  Section of this Lease
entitled "OPTIONS TO EXPAND" are preserved without variance.  Furthermore Lessee
confirms that the space on the seventh  (7th) floor of the Building,  containing
approximately 3,063 square feet of rentable area,  currently identified as Suite
725 and previously leased to the Thomas Cook  Partnership,  has become available
to Lessor, that Lessor has offered this space to Lessee in conjunction with this
transaction,  and that Lessee has  elected not to lease such space from  Lessor.
Lessor is specifically granted the right to lease such space to a Generic Tenant
or to  another  tenant of the  Building,  with  rights to extend the term of any
lease or the right to expand  their  respective  leased  premises to include the
space identified as. a Negotiation Area have expired, been earlier terminated or
been waived,  provided  that if and when such space again  becomes  available to
Lessor for  leasing  (after the  expiration  or waiver of all rights  granted to
other  tenants of the Building in accordance  with the  provisions of Subsection
(A) of this  Section)  that Lessee shall be offered such space as a  Negotiation
Area pursuant to this Section of the Lease.

         (E) In the event  Lessee does not deliver a written  notice of exercise
of its rights to such Negotiation Area, or Lessor and Lessee are unable to reach
agreement  upon the  business  terms  and  conditions  for the  leasing  of such
Negotiation  Area(s)  within said thirty (30) day period,  then  Lessee's  first
right to negotiate with respect to such  Negotiation Area shall be null and void
for the remaining term of this Lease.  Furthermore,  in no event shall Lessor be
required to negotiate for the leasing of only a portion of any Negotiation  Area
offered by Lessor.

         (F) If Lessee duly and properly  exercises  the option to terminate the
term of this Lease as provided in the Section of this Lease entitled  "OPTION TO
TERMINATE", then Lessee by giving such notice of its election to terminate shall
be deemed to have waived  thereafter any further rights under this Section,  and
Lessor  shall no longer be  obligated  to  afford to Lessee  the first  right to
negotiate for any Negotiation Areas that subsequently become available after the
date of Lessee's  notice of its election to terminate  this Lease.  Additionally
Lessee  shall be obligated  to pay to Lessor as  consideration  for the right to
exercise such right of termination with regard to any Negotiation Area leased by
Lessee a termination  payment  calculated  as provided in Subsection  (E) of the
Section of this Lease entitled "OPTION TO TERMINATE."  Such termination  payment
shall be due and payable to Lessor with the termination  Payment provided for in
that Section of this Lease.

         (G) Lessor shall have prepared an addendum  setting forth the terms and
conditions for Lessee's  leasing of a Negotiation  Area.  Thereafter  Lessor and
Lessee agree in good faith to proceed to  diligently  negotiate and execute such
addendum  with  intent of having  such  addendum  executed  by Lessor and Lessee
within  sixty (60) days after the date Lessor and Lessee agree upon the business
terms for the leasing of that Negotiation Area.

         (H) At the time Lessor delivers the Negotiation Area to Lessee,  Lessee
and Lessor shall also enter into a document similar in form and substance to the
document  attached to this Lease as Exhibit D-4,  noting the date of delivery of
Negotiation Area to Lessee and related  matters.  Execution of a document in the
form of the document appearing as Exhibit D-4 shall not be deemed a condition to
the  occurrence  of the  commencement  date of this  Lease  with  regard to that
Negotiation Area.

         (I) This  Section  of the Lease  shall  become  null and void and of no
further  force and effect if Lessee  assigns this Lease or has  subleased at any
one time in excess of thirty percent (30%) of the Demised Premises, to any party
other than a qualified party identified in Subsection (D) of the Section of this
Lease entitled "ASSIGNMENT AND SUBLETTING. "


12.    ASSIGNMENT AND SUBLETTING

         (A) Lessee may not assign or otherwise  transfer this Lease,  or sublet
(including  permitting  occupancy or use by another party) the Demised Premises,
or any part thereof,  without first giving Lessor thirty (30) days prior written
notice of Lessee's  intention to assign this Lease or sublet all or a portion of
the Demised Premises and obtaining  Lessor's prior consent to Lessee's intention
to assign or sublet.  Notwithstanding the foregoing, Lessee will not be required
to give  Lessor  prior  notice of any  occupancy  by a  Permitted  Licensee  (as
hereinafter  defined),  unless such  occupancy  when viewed in light of Lessee's
then  current  overall  pattern  of  subleasing  will  cause  Lessee  to be then
occupying  for its  regular  business  operations  (and  exclusive  of any  area
occupied by any Permitted  Licensee) less than seventy percent (70%) of the then
rentable area of the Demised Premises. Where Lessee is required by the foregoing
to give prior notice of Lessee's intention to sublet, Lessee shall also identify
the area of the Demised  Premises  Lessee intends to sublet.  Within thirty (30)
days after  receipt of said notice of intent to assign or sublet,  Lessor  shall
have the option (i) to elect to terminate the Lease, if Lessee desires to assign
this  Lease,  (ii) to  terminate  the Lease with  regard to that  portion of the
Demised  Premises  which  Lessee  intends  to  sublet,  if  Lessee  will then be
subletting  to all parties,  including  all  Permitted  Licensees,  in excess of
thirty  percent  (30%) of the Demised  Premises,  or (iii) to sublet from Lessee
that portion of the Demised  Premises  Lessee  intends to sublet for the term of
years that  Lessee  desires  to sublet,  at the rate and upon the same terms and
conditions as Lessee is leasing the Demised  Premises from Lessor if Lessee will
then be subletting to all parties,  including all Permitted Licensees, in excess
of thirty  percent  (30%) of the  Demised  Premises.  Lessor  may  exercise  the
applicable  option  only by giving  Lessee  written  notice of its  election  to
exercise the option within said thirty (30) day period.

         Where  Lessor  fails  to  timely  exercise  any  applicable  option  to
terminate  or sublet as  provided  above,  or Lessor  affirmatively  consents to
Lessee's  intention  to assign  this Lease or sublet  space  within the  Demised
Premises,  then Lessee may thereafter assign this Lease or sublet the identified
portion of the Demised Premised,  but shall be required to obtain Lessor's prior
written  consent to (i) any  assignee  or any  sublessee  (which  consent to the
proposed assignee or sublessee may not be unreasonably withheld, contingent upon
the proposed assignee or sublessee being similar in kind and character to Lessee
and financially reliable), and (ii) the form of documentation  implementing such
assignment or subletting.

         Lessor  shall have  thirty  (30) days after  receipt of a request  from
Lessee to approve or  disapprove  a proposed  assignee or  sublessee.  If Lessor
shall fail to approve  any  assignee  or  sublessee  within said thirty (30) day
period,  then such  assignee or  sublessee  shall be deemed  approved by Lessor.
Lessor  shall  have  thirty  (30) days after  receipt  of a proposed  assignment
agreement or sublease from Lessee, to approve or disapprove such instrument.  If
Lessor shall fail to approve or disapprove such instrument, then such instrument
shall be deemed approved by Lessor.

         In the event that Lessor has  approved a proposed  assignee or proposed
sublease, and approved the instrument  accomplishing an assignment of this Lease
or a  sublease  of the  identified  space in the  Demised  Premises,  and Lessee
thereafter  fails to present to Lessor any assignment  agreement or any sublease
(including occupancy  agreement),  fully executed by the parties hereto,  within
one  hundred  eighty  (180)  days  after the date that  Lessor is deemed to have
approved  Lessee's  intention  to assign or sublet,  Lessee may not assign  this
Lease or sublet (or permit the  occupancy  of) all or any portion of the Demised
Premises to said party without again affording Lessor the option to terminate or
sublease as afforded in the first paragraph of this subsection (A).

         Notwithstanding the foregoing  concerning the need for Lessee to obtain
Lessor's prior consent to Lessee's intent to sublet (or permit the occupancy of)
a portion of the Demised  Premises,  and  Lessor's  prior  consent to a proposed
sublessee (or occupant), Lessee shall not be required to obtain Lessor's consent
to permit a party identified as a Permitted  Licensee to use and occupy (but not
sublease) any portion of the Demised Premises,  unless Lessee would then at that
time be  subleasing  (including  permitting  occupancy  of) in  excess of thirty
percent (30%) of the then rentable area of the Demised Premises. If Lessee would
be subletting  to such party or would then be subleasing  more than thirty (30%)
of the then  rentable  area of the  Demised  Premises,  the  provisions  of this
subsection  related to the need for Lessee to obtain Lessor's  various  consents
will apply. For the purposes of this Lease, a "Permitted  Licensee" shall mean a
retired  officer  or  employee  of  Lessee,  any  party  that is a  client  or a
consultant of Lessee or an officer or employee thereof,  and any party that is a
client or  consultant  of any client or  consultant  or an  officer or  employee
thereof,  which party uses or occupies,  but does not sublease, a portion of the
Demised  Premises  either in  conjunction  with or to support the carrying on of
Lessee's  regular  business or as a result of an ongoing  business  relationship
between Lessee and any client or consultant of Lessee.

WhereLessor is  permitted to  terminate  or, as  applicable,  sublet,  then,  if
     Lessor  does so  elect  to  terminate  or  sublet,  the  effective  date of
     termination,  or the  effective  date of  commencement  of the  sublease to
     Lessor,  shall be mutually agreed upon by Lessor and Lessee. If the parties
     cannot agree upon a termination date or upon a sublease  commencement date,
     the termination date or sublease  commencement  date shall be the date that
     is sixty (60) days after the date  Lessor  received  the notice that Lessee
     desired  to assign the Lease or sublet  all or any  portion of the  Demised
     Premises. Upon termination, all of the rights and obligations of Lessor and
     Lessee  under the terms of this Lease shall be  terminated,  or  terminated
     with regard to that portion of the Demised  Premises  that Lessee  notified
     Lessor that Lessee desired to sublet,  except that Lessee shall continue to
     be  obligated  to pay rent and all other  charges for the Demised  Premises
     which accrue to the date of termination.


         (B) Lessee shall reimburse to Lessor, as additional rent, all costs and
expenses,  including  reasonable  attorney's fees in an amount not to exceed Two
Thousand and 00/100ths Dollars ($2,000.00),  which Lessor incurs by reason of or
in connection with any assignment,  sublease,  or leasehold mortgage proposed or
granted  by  Lessee  (whether  or not  permitted  under  this  Lease),  and  all
negotiations  and actions with respect  thereto,  such additional rent to be due
and payable within fifteen (15) days of receipt of a statement of such costs and
expenses from Lessor.

(C)  No  assignment  of this Lease shall be  effectuated  by operation of law or
     otherwise without the prior written consent of Lessor.  For the purposes of
     this  Lease,  (i)  the  transfer  of  fifty  percent  (50%)  or more of the
     ownership  interest of Lessee or the transfer  and/or issuance of more than
     fifty percent (50%) of the authorized  voting stock of Lessee, if Lessee is
     not a publicly  held  corporation,  to any persons or entities that are not
     owners or stockholders of Lessee on the date of execution of this Lease, or
     (ii) the sale,  transfer or other conveyance of all or substantially all of
     Lessee's assets, shall be deemed an assignment of this Lease thereby giving
     Lessor  the right to  consent  to such  transaction  and/or  the  option to
     terminate this Lease as provided above.  Notwithstanding the foregoing,  in
     the event of a  transfer  under (i)  above,  or a sale,  transfer  or other
     conveyance under (ii) above, and where Lessee,  in the case of (i) above or
     the new entity or its  controlling  partner in the case of (ii) above,  can
     demonstrate to Lessor to Lessor's reasonable satisfaction that such party's
     ability to fulfill its obligations  under the Lease  immediately after such
     event is substantially  equal to or better than Lessee's ability to fulfill
     those obligations during the full calendar year immediately  preceding such
     event under (i) or (ii),  then,  provided the foregoing  financial test has
     been  satisfied,  Lessor shall not have the right to terminate  this Lease,
     but Lessee shall be obligated to notify  Lessor of such  transfer,  or such
     sale,  transfer or  conveyance  and shall be  required  to obtain  Lessor's
     consent as otherwise  provided for in this Lease with regard to approval of
     parties who may become  assignees of this Lease or  sublessees  of all or a
     portion of the Demised Premises.

         (D)  Notwithstanding the foregoing  provisions of this Section,  Lessee
has the right to assign this Lease or sublet the Demised Premises in whole or in
part to any  subsidiary  or  affiliate  upon  giving  Lessor ten (10) days prior
written notice of such assignment or subleasing.  Such an assignment or sublease
shall not trigger Lessor's right to terminate the Lease or subsequently  require
Lessor's  consent to any assignee or sublessee.  A "subsidiary"  of Lessee shall
mean any  corporation  not less than fifty  percent  (50%) of whose  outstanding
voting stock shall, at the time, be owned, directly or indirectly, by Lessee. An
"affiliate" of Lessee shall mean any corporation which,  directly or indirectly,
controls or is controlled by or is under common control with Lessee. For purpose
of the definition of "affiliate," the word "control" (including  "controlled by"
and "under  common  control  with"),  as used with  respect to any  corporation,
partnership, or association, shall mean the possession,  directly or indirectly,
of the power to direct or cause the direction of the  management and policy of a
particular  corporation,   partnership  or  association,   whether  through  the
ownership of voting securities or by contract or otherwise.



         (E)  Notwithstanding any other provision of this Lease to the contrary,
Lessee shall have no right to transfer,  assign,  sublet,  enter into license or
concession  agreements,  or  mortgage  or  hypothecate  this  Lease or  Lessee's
interest in the Demised Premises or any part thereof to a foreign  government or
to any individual or entity whereby enforcement of the obligations of the Lessee
under this Lease  might be limited by  sovereign  immunity.  Any such  attempted
transfer,  assignment,  subletting, license or concession agreement, mortgage or
hypothecation  shall be void and confer no rights on such foreign  government or
individual or entity.

         (F) The consent by Lessor to any  assignment or subletting to any party
other than Lessor,  including a subsidiary or affiliate,  shall not be construed
as a waiver or release of Lessee from the terms of any  covenant  or  obligation
under this Lease. Lessor's collection or acceptance of rent from any assignee of
Lessee  shall not  constitute  a waiver or release of Lessee of any  covenant or
obligation  contained in this Lease, nor shall any such assignment or subletting
be construed to relieve  Lessee from giving  Lessor said thirty (30) days notice
or from obtaining the consent in writing of Lessor to any further  assignment or
subletting.  In the event that Lessee is in default of any term or  provision of
this Lease,  Lessee hereby  assigns to Lessor the rent due from any subtenant of
Lessee and hereby  authorizes and directs each such subtenant,  upon notice from
Lessor,  to pay said rent  directly to Lessor,  the  collection or acceptance of
rent from any  subtenant in such  instance not to constitute a waiver or release
of Lessee of any covenant or obligation contained in this Lease.

         (G) Lessee may not  mortgage or encumber  this Lease  without the prior
written consent of Lessor.


13.      ALTERATIONS

         (A)  Without  first   obtaining   Lessor's  prior  written  consent  as
hereinafter provided, Lessee shall make no alterations,  installation, additions
or  improvements  in or to the  Demised  Premises or the  Building,  except that
Lessee may make changes of a cosmetic nature to the tenant  improvements  within
the Demised Premises (e.g. painting, installation of wall covering, installation
of carpeting, etc.), but only where such changes by their nature will not impact
the base  building  structure  or base  building  systems or will not be readily
apparent and visible  from the exterior of or the common areas of the  Building,
(hereinafter   collectively  such  alterations,   installations,   additions  or
improvements, other than cosmetic changes, being called "Alterations").  Consent
by Lessor to Alterations shall not be unreasonably withheld,  except that Lessor
may withhold its consent for any reason with regard to requested  Alterations by
Lessee which could, in Lessor's  reasonable  opinion,  (i) adversely  affect the
structure of the Building or the mechanical,  plumbing or electrical  systems of
the Building,  (ii) cause the  imposition of additional  costs or obligations on
Lessor, including but not limited to adversely affecting the insurance rating of
the  Building,  or (iii) affect the quiet  enjoyment  of other  tenant(s) of the
Building.  For all  Alterations,  Lessee,  at its sole cost and  expense,  shall
provide Lessor with a copy of the original or revised full floor  mechanical and
electrical  plans for the floor or  floors  on which the  Alterations  are to be
made,  revised by Lessee's  architect  and Lessor's  engineers to show  Lessee's
proposed Alterations.  In the event Lessor becomes aware of any Alterations that
were made by Lessee  without the written  consent of Lessor,  then Lessor  shall
promptly  inform  Lessee  of such in  writing  and  Lessor  shall  inspect  such
Alterations.  Lessee  shall then have  thirty  (30) days to provide  Lessor with
architectural,  mechanical and electrical plans, as applicable,  supporting such
Alterations and to receive Lessor's  consent to the  Alterations,  which consent
shall not be unreasonably withheld.  However,  Lessor may condition such consent
upon Lessee making certain  corrections or  modifications to such Alterations to
bring the  Alterations  into  compliance  with Building  standards or applicable
codes. If Lessee makes any  Alterations and does not obtain Lessor's  consent to
such   Alterations,   or  if  Lessee  refuses  to  timely  make  corrections  or
modifications  to Alterations  previously  made by Lessee that are  subsequently
discovered by Lessor,  then Lessor shall have the right, but not the obligation,
to require  that such  Alterations  be removed or  modified.  If Lessee fails to
remove or modify the  Alterations  as required by Lessor within thirty (30) days
after Lessee's receipt of Lessor's written request, Lessor may correct or remove
the  same,  and  Lessee  shall be  liable  for any and all  reasonable  expenses
incurred by Lessor in the  performance  of this work. All  Alterations  shall be
made at Lessee's  sole  expense,  at such times and in such manner as Lessor may
designate,  and only by such contractors or mechanics as are approved in writing
by  Lessor.  All  Alterations  and other  work  undertaken  by Lessee and by any
contractor  or  mechanic  shall be in  accordance  with  construction  rules and
regulations  promulgated from time to time by Lessor.  Lessor reserves the right
to require that  Alterations  be  performed  at a time other than during  normal
business hours if Lessor,  in its  reasonable  discretion,  determines  that the
performance  of such  Alterations  is likely to  disturb,  disrupt or  otherwise
inconvenience  other tenant(s) or occupants(s) of the Building (such as, but not
limited to, those Alterations requiring core drilling,  hammering, etc. Approval
of  contractors or mechanics by Lessor,  which approval may not be  unreasonably
withheld,  shall be based  upon the  contractors  or  mechanics  being  properly
licensed, their financial posture, experience and past job performance.

         (B)  Alterations  proposed by Lessee and approved by Lessor  during the
period from the Commencement  Date 1 to Rent Commencement Date 2 are hereinafter
called the  "Initial  Alterations,  ' which  Initial  Alterations  shall also be
deemed  "Alterations"  for all  purposes  under this Lease,  except as otherwise
provided in this Subsection.

                  (i) Subject to the grant and  application of the Allowance (as
hereinafter defined) by Lessor as herein provided, the Initial Alterations shall
be undertaken by Lessee at its sole cost and expense.  Lessee,  at its sole cost
and  expense,  shall cause its  architect  to prepare,  on Lessee's  behalf,  an
initial set of architectural  working drawings for the Initial  Alterations (the
"Architectural  Drawings"),   which  Architectural  Drawings  shall  reflect  in
sufficient  detail  Lessee's  space  plans and  specifications  for the  Initial
Alterations to be made in or to the Demised Premises in connection with Lessee's
initial occupancy of the Demised Premises,  and shall include among other things
dimensioned  partition  plans,  electrical,  data  and  telephone  requirements,
reflected  ceiling plan and lighting  requirements,  ceiling  details,  Lessee's
requirements and  specifications  for additional  HVAC, if any,  interior office
door requirements,  environmental and electrical specifications and requirements
for all of Lessee's  equipment,  fixtures and kitchen  appliances,  its millwork
details  and  other  millwork  requirements,  final  finish  selections  and its
complete and detailed  space plan drawings for the Initial  Alterations  for the
Demised  Premises.  Lessee shall have the  Architectural  Drawings  delivered to
Lessor  for the  review  and  approval  of  Lessor  and  Lessor's  architect  or
supervising  engineer.  Within ten (10) business days following Lessor's receipt
of the  Architectural  Drawings,  Lessor shall review and approve in writing the
Architectural Drawings and finish selections.  In the event that Lessor fails to
review and approve the  Architectural  Drawings within the ten (10) business day
period,  then  Lessor's  approval  of the same shall be deemed  given.  Lessor's
approval may not be unreasonably  withheld or delayed, but may be conditioned in
the  reasonable   discretion  of  Lessor.   Any  changes  or  revisions  to  the
Architectural  Drawings  made at the request of Lessor shall be made by Lessee's
architect at Lessee's sole cost and expense,  which costs and expenses  shall be
paid out of the  Allowance.  Lessee  shall  retain  and  enter  into a  separate
agreement  with  the  engineering  firm  of  General   Engineering,   Inc.  (the
"Engineer") to prepare a set of mechanical,  electrical and plumbing engineering
drawings for Initial  Alterations  for the Demised  Premises  (the  "Engineering
Drawings") at Lessee's sole cost and expense.  All revisions to the  Engineering
Drawings,  including  those caused by Lessee's  revisions  to the  Architectural
Drawings once approved by Lessor, shall be made by the Engineer at Lessee's sole
cost and expense,  which costs and expenses  shall be paid out of the Allowance.
Lessee shall submit the  Engineering  Drawings  (and all  revisions  thereto) to
Lessor for prior  review and  written  approval  by Lessor,  its  architect  and
supervising engineer.  Lessor shall respond to the Engineering Drawings (and any
revisions thereto) within ten (10) business days of its receipt thereof.  In the
event that Lessor fails to review and approve the  Engineering  Drawings  within
the ten (10) business day period,  then  Lessor's  approval of the same shall be
deemed given. Lessor's approval may not be unreasonably withheld or delayed, but
which may be  conditioned  in Lessor's  reasonable  discretion.  Upon receipt of
Lessor's approval of the Engineering Drawings,  Lessee shall cause its architect
to affix its architectural stamp to four (4) sets of the Architectural  Drawings
for  Lessee's  use in filing its  building  permit  application  for the Initial
Alterations.


(ii) Prior to the commencement of  construction,  installation or fabrication of
     the Initial  Alterations,  Lessee shall furnish to Lessor copies of any and
     all building or other construction  permits required for the performance of
     the Initial Alterations. Upon completion of its Initial Alterations, Lessee
     shall also furnish to Lessor a complete set of "as built"  drawings for the
     Demised Premises.  The Initial Alterations shall be performed by one (1) of
     the following  general  contractors to be retained by Lessee  pursuant to a
     separate  agreement  ("Lessee's  General  Contractor"):  Hitt Construction,
     Inc.,  G & F  Associates,  Inc.,  Turner  Construction  Company,  and Clark
     Construction  Company.  Lessee shall manage the construction process of all
     Initial  Alterations  directly  or hire at its  sole  cost  and  expense  a
     construction   manager,   reasonably  acceptable  to  Lessor.  All  Initial
     Alterations  shall be undertaken by Lessee and Lessee's General  Contractor
     in accordance with the  construction  rules and regulations  promulgated by
     Lessor from time to time.  On the Initial  Alterations,  Lessee  recognizes
     that Lessor shall incur substantial oversight obligations,  and thus agrees
     to pay to Lessor a  management  oversight  fee,  billed at an hourly  rate,
     which in the aggregate may not exceed Three Thousand and 00/100ths  Dollars
     ($3,000.00).  Any construction management fees and the management oversight
     fee shall be paid from the Allowance.

(iii)Lessee  hereby  designates  and  authorizes  (the  "Lessee's  Designee") to
     receive all  approvals  from Lessor,  to make all  decisions  and grant all
     approvals  on behalf of Lessee  with  respect to design,  installation  and
     construction  of the Initial  Alterations,  and to furnish to Lessor or its
     architect  such  information  as they may request or require in  connection
     with the review and  approval of each of the  Architectural  Drawings,  the
     finish  selections,  and  the  Engineering  Drawings.  Lessor  may  contact
     Lessee's Designee at the following address and numbers:

individual  or  individuals  to make all  decisions  and grant all  approvals on
behalf of Lessor with respect to design, and installation,  construction  and/or
fabrication of the Initial Alterations.

         (v) In  connection  with Lessee's  leasing of the Demised  Premises and
construction  of the  Initial  Alterations,  Lessor  shall  provide to Lessee an
improvements  allowance  (the  "Allowance")  of One Million Three Hundred Thirty
Thousand Nine Hundred Twenty-Two and 00/100ths Dollars ($1,330,922.00),  for (a)
the hard  construction  costs  incurred by Lessee to  construct  and install its
Initial Alterations in the Demised Premises,  (b) any construction related items
(including but not limited to,  architectural  and other consulting fees, permit
fees,  computer,  telephone  and  communications  facilities,  and  construction
management  fees),  and (c) the costs of office  personal  property  of Lessee,-
including  equipment and furniture.  This  Allowance has been  calculated at the
rate of Twenty-Nine and 50/100ths  Dollars  ($29.50)  multiplied by the rentable
area of the Demised  Premises.  Up to One  Hundred  Thirty-five  Thousand  Three
Hundred Forty-eight and 00/100ths Dollars  ($135,348.00) of the Allowance may be
used for the  acquisition  of furniture  and other office  personal  property of
Lessee. Lessee shall submit to Lessor (but on a monthly basis only) invoices for
the costs  incurred by Lessee in performing  its Initial  Alterations,  together
with signed partial waivers and partial  releases of mechanic's  liens executed,
as applicable, by Lessee's architect, and by Lessee's General Contractor and the
subcontractors  who performed  such work, as reflected on such  invoices.  After
inspection  and  approval  of the  portion(s)  of  the  Initial  Alterations  as
reflected  by  such  invoices  and  verification  of the  invoices  and  waivers
submitted,  Lessor  shall pay to Lessee (or if  directed in writing by Lessee or
Lessee's  architect,  Lessor shall pay to Lessee's  General  Contractor)  or, as
applicable,  Lessor shall reimburse to Lessee, the appropriate amounts requested
by the  invoices  within  thirty  (30) days of  Lessee's  request  therefor.  In
connection  with any final  disbursement of the Allowance and in addition to the
invoices  and partial lien waivers and partial  lien  releases  required  above,
Lessee shall also submit to Lessor final lien releases and final lien waivers of
mechanic's liens executed, as applicable, by Lessee's architect, and by Lessee's
General Contractor and all other contractors and subcontractors  which performed
the Initial Alterations, and such other documentation or information that Lessor
may reasonably  require for any final  disbursement of the Allowance,  such as a
copy of the certificate of occupancy of the Demised Premises or a certificate of
completion  of the Initial  Alterations  from Lessee's  architect.  In no event,
however,  shall Lessor be obligated to reimburse Lessee for any amount in excess
of the total amount of the Allowance.  Lessee shall submit all such invoices and
requests  for  reimbursement  to Lessor  on or before  December  31,  1997.  The
Allowance  shall be used first to reimburse  Lessee for all costs  arising under
item (a) above. After reimbursement for those costs arising under item (a) above
in this  Subsection,  any remaining  portion of the Allowance shall be available
for  reimbursement  of  items  arising  under  items  (b) and (c)  above in this
Subsection.  After the  reimbursement  of all costs arising under items (a), (b)
and (c) above in this  Subsection,  Lessee  may elect to have  Lessor  apply any
unused portion of the remaining  Allowance to Monthly Rent next due and owing by
providing  written  notice of its  election to Lessor on or before  December 31,
1997.

         (vi)  Notwithstanding  the foregoing of this  Subsection,  Lessor shall
have no obligation to credit any unused portion of the Allowance to Monthly Rent
or to reimburse  Lessee for any costs under items (a), (b) and (c) of Subsection
(B)(v)  above of this  Section if (a) Lessee  fails to submit the  invoices  and
requests for  reimbursement to Lessor on or before December 31, 1997, or (b) if,
at the time the unused  portion of the  Allowance  would  otherwise be available
from crediting to such monetary obligation of Lessee or at the time Lessee makes
a request for  reimbursement  or at any time  thereafter up to and including the
date Lessor makes any such  reimbursement  to Lessee or credit to Monthly  Rent,
Lessee is in default,  after the giving notice and the passage of the applicable
period to cure, of its obligation to pay Monthly Rent.

         (C) All Alterations to the Demised Premises,  whether made by Lessor or
Lessee,  and whether at Lessor's or Lessee's  expense,  or the joint  expense of
Lessor and Lessee,  shall be and remain the property of Lessor. Any replacements
of any property or improvements of Lessor,  whether made at Lessee's  expense or
otherwise, shall be and remain the property of Lessor.

         (D) At the expiration or earlier  termination of the term of the Lease,
Lessor may elect to require Lessee to remove all or any part of the  Alterations
made by Lessee subsequent to the Commencement Date, provided that Lessor, at the
time of its  consent  and  approval  of  Alterations,  specifies  to Lessee,  in
writing,  that certain  elements of the Alterations  would have to be removed at
the expiration or earlier termination of the term of this Lease. Notwithstanding
the  foregoing,  if  Lessor  will  require  the  removal  of any of the  Initial
Alternations,  Lessor  shall  note  on the  Architectural  Drawings  and/or  the
Engineering  Drawings any portion or element of Initial Alterations which Lessor
will require  Lessee to remove at the  expiration or earlier  termination of the
term of this Lease. Removal of Alterations, whether at Lessor's determination as
provided  for  above or at  Lessee's  election,  shall be at  Lessee's  cost and
expense,  and Lessee agrees, at Lessor's  election,  (i) to repair any damage to
the  Building  caused by said  removal and to restore the Demised  Premises to a
condition no less than the Building  standard  level as identified in Exhibit B,
or (ii) pay Lessor,  as  additional  rent,  for all costs  incurred by Lessor to
undertake such repairs and restoration.

         (E) Lessee shall remove all of Lessee's  property at the  expiration or
earlier  termination of the Lease.  In the event Lessee does not remove Lessee's
property at the expiration or earlier  termination  of the Lease,  such property
shall become the property of Lessor.

         (F) In the event Lessee fails to remove its property or the Alterations
requested  to be  removed  by Lessor  on or before  the  expiration  or  earlier
termination  of the term of the Lease,  then Lessor may remove such property and
Alterations  from the Demised  Premises at Lessee's  expense,  and Lessee hereby
agrees to pay to Lessor, as additional rent, the reasonable cost of such removal
together  with any and all damages which Lessor may suffer and sustain by reason
of the failure of Lessee to remove the same.  Lessor shall  provide  Lessee with
supporting invoices and related  documentation  reasonably evidencing such costs
of removal and of damages  resulting  from the same.  Said amount of  additional
rent shall be due and payable upon  receipt by Lessee of a written  statement of
costs and damages from Lessor.


14.      LIENS

         (A) If any  mechanic's  or other  lien is  filed  against  the  Demised
Premises,  or the Building of which the Demised  Premises are a part,  for work,
labor,  services, or materials,  done for or supplied to or claimed to have been
done or supplied to Lessee, such lien shall be discharged by Lessee, at its sole
cost and  expense,  within ten (10) days from the date Lessee  receives  written
demand from Lessor to discharge  said lien, by the payment  thereof or by filing
any bond  required  by law.  If Lessee  shall fail to  discharge  any such lien,
Lessor  may,  at its option,  discharge  the same and treat the cost  thereof as
additional  rent, due and payable upon receipt by Lessee of a written  statement
of costs from Lessor.  It is hereby  expressly  covenanted  and agreed that such
discharge of any lien by Lessor  shall not be deemed to waive or release  Lessee
from its default under the Lease for failing to discharge the same.

         (B) Lessee will indemnify and hold harmless Lessor from and against any
and all claims,  damages and expenses incurred by Lessor, arising from any liens
placed  against the Demised  Premises or the Building and the land upon which it
is situated, as a result of Lessee undertaking  construction work in the Demised
Premises at its own cost and under its own control and direction,  or making any
Alterations to the Demised Premises.


15.      MAINTENANCE BY LESSEE

         (A)  Lessee  shall  keep the  Demised  Premises  and the  fixtures  and
equipment  therein in clean, safe and sanitary  condition,  shall take good care
thereof,  and shall  suffer no waste or injury  thereto.  At the  expiration  or
earlier  termination  of the term of this  Lease,  Lessee  shall  surrender  the
Demised  Premises  broom clean and in the same order and condition in which they
were on the  Commencement  Date,  ordinary  wear  and  tear  and  damage  by the
elements, fire and other insured casualty excepted.

         (B) To the extent that Lessee's use or uses of the Demised  Premises or
Lessee's  manner of operation  creates a need or  requirement  under  applicable
statute,  ordinance or  regulation  of any  governmental  authority to modify or
alter the Demised Premises,  supporting  facilities,  or access thereto,  or the
manner of  operation,  maintenance  and repair  thereof,  Lessee  shall be fully
responsible for the costs to undertake such changes, and to obtain approval from
Lessor pursuant to the Section of this Lease entitled "ALTERATIONS" to undertake
such changes.

16.      SIGNS AND ADVERTISEMENTS

         (A) No sign,  advertisement  or  notice  shall be  inscribed,  painted,
affixed or displayed  on any part of the outside or the inside of the  Building,
except with Lessor's prior written consent and then only in such place,  number,
size, color and style (i.e.,  Building  standard  lettering) as is authorized by
Lessor.  If any such sign,  advertisement  or notice is exhibited  without first
obtaining  Lessor's written  consent,  Lessor shall have the right to remove the
same. and Lessee shall be liable for any and all expenses  incurred by Lessor by
said  removal,  as  additional  rent.  Notwithstanding  the  foregoing,   Lessor
recognizes  Lessee's  existing signage in place related to the Original Premises
as acceptable and approved under this Subsection of the Lease.

         (B) Lessor agrees to display Lessee's name on the Building directory in
the size and style of lettering used by Lessor, at Lessee's expense.  Lessee may
display  its name on the main entry door of the  Demised  Premises  in  Building
standard color, size and style of lettering, at Lessee's expense.

         (C) Lessor shall have the right to prohibit any published advertisement
of Lessee which in its opinion tends to impair the reputation of the Building or
its  desirability  as a high quality office  building,  and, upon written notice
from Lessor,  Lessee shall  immediately  refrain from and  discontinue  any such
advertisement.

17.      DELIVERIES AND MOVING OF LESSEE'S PROPERTY

No   furniture,  equipment  or other bulky  matter of any  description  shall be
     received into the Building or carried in the elevators except in the manner
     and during the times  approved  by Lessor.  Lessee  shall  obtain  Lessor's
     determination  prior to moving said property into the Building.  All moving
     of  furniture,  equipment and other  material  within the public and common
     areas in and about the  Building  shall be in and manner  and during  those
     times  reasonably  determined  by  Lessor  and  shall  be  accomplished  in
     accordance  with reasonable  policies and procedures  established by Lessor
     from time to time uniformly applied. Lessor shall have the right to monitor
     compliance by Lessee and its agents with such policies and procedures,  but
     Lessor  who  shall,  however,  not be  responsible  for any  damage to such
     equipment  or other  bulky  matter,  or for the  charges  for  moving  such
     equipment  or other  bulky  matter in  accordance  with such  policies  and
     procedures.  Lessor  shall  have  the  sole  right  to  determine  the load
     capacities  of the  elevators  of the Building and to determine if Lessee's
     property can be safely transported in the elevators,  applying commercially
     reasonable  standards  that would be applied by  landlords  and managers of
     other office buildings  comparable to the Building.  Lessee agrees promptly
     to remove from the  sidewalks  adjacent to the Building any of the Lessee's
     furniture, equipment or other material there delivered or deposited.

18.      LESSEE'S EQUIPMENT

         (A) Lessee  will not  install or operate in the  Demised  Premises  any
electrically operated equipment or other machinery, other than typewriters, word
processing  machines,  personal desk top  computers,  adding  machines,  radios,
televisions,   tape  recorders,   dictaphones,   bookkeeping  machines,  copying
machines,  clocks,  and other business machines and equipment  normally employed
for general  office use which do not require high  electricity  consumption  for
operation,  without first obtaining the prior written consent of Lessor, who may
condition such consent upon payment by Lessee of additional rent as compensation
for additional  consumption of electricity  and/or other utility services.  Such
additional  rent shall be in addition to Lessee's  obligations,  pursuant to the
Section of this Lease entitled.  "OPERATING  EXPENSES,  OPERATING COSTS AND REAL
ESTATE TAXES," to pay its proportionate share of increases in Operating Costs.

         If any or all of Lessee's equipment requires electricity consumption in
excess of the  capacity  of the  electrical  system  installed  by Lessor in the
Demised Premises,  all additional  transformers,  distribution panels and wiring
that may be required to provide the amount of electricity  required for Lessee's
equipment  shall be  installed  by Lessor at the cost and expense of Lessee.  If
Lessee's  equipment  causes  Lessee's  consumption  of  electricity to exceed an
average of five (5) watts per rentable  square foot, or if such  equipment is to
be  consistently  operated beyond the normal Building hours of 8: 00 a. m. to 8:
00 p. in., Monday through Friday, and 9:00 a.m. to 6:00 p.m. on Saturday, Lessor
may install at its option (i) a separate electric meter for the Demised Premises
at Lessee's  sole cost and  expense,  or (ii) a separate  meter for the specific
equipment  that is causing  Lessee's  excessive  consumption  of  electricity at
Lessee's sole cost and expense.  In the event Lessor  installs a separate  meter
for the  Demised  Premises,  Lessee  shall then pay the cost of  electricity  it
consumes as recorded by such meter  directly  to the  electric  company,  and an
appropriate  adjustment  shall  be  made  to  Lessee's  proportionate  share  of
Operating Costs to reflect Lessee's reduced  consumption of electricity  because
of  such  separate  metering  of  the  Demised  Premises.  In the  event  Lessor
separately meters the specific equipment, Lessee shall be billed periodically by
Lessor based upon such  consumption and no adjustment  shall be made to Lessee's
proportionate share of Operating Costs.

(B)  Lessee  shall not install any  equipment  of any kind or nature  whatsoever
     which will or may necessitate any changes, replacements or additions to, or
     in  the  use  of,  the  water  system,  heating  system,  plumbing  system,
     air-conditioning  system,  or electrical  system of the Demised Premises or
     the Building  without first  obtaining the prior written consent of Lessor.
     Business machines and mechanical  equipment belonging to Lessee which cause
     noise or vibration that may be transmitted to the structure of the Building
     or to any space therein to such a degree as to be  objectionable  to Lessor
     or to any tenant in the  Building  shall be  installed  and  maintained  by
     Lessee,  at Lessee's  expense,  on vibration  eliminators  or other devices
     sufficient to eliminate such noise and vibration.

         (C) Lessor shall have the right to prescribe the weight and position of
all heavy equipment and fixtures, including, but not limited to, data processing
equipment, record and file systems, and safes which Lessee intends to install or
locate within the Demised  Premises.  Lessee shall obtain  Lessor's prior review
and approval  before  installing or locating heavy equipment and fixtures in the
Demised Premises, and if installation or location of such equipment or fixtures,
in  Lessor's   reasonable   opinion,   requires   structural   modifications  or
reinforcement  of any portion of the Demised  Premises or the  Building,  Lessee
agrees to reimburse Lessor, as additional rent, for any and all reasonable costs
incurred by Lessor to make such required  modifications or  reinforcements,  and
such  modifications  or  reinforcements  shall  be  completed  prior  to  Lessee
installing  or locating  such  equipment  or  fixtures in the Demised  Premises.
Lessee  shall  reimburse  Lessor  within  thirty  (30)  days of  receipt  of any
statement setting forth those costs.





19.      SERVICES AND UTILITIES

(A)  From  and  after  the  Commencement  Date 1  with  regard  to the  Original
     Premises,  from and after Commencement Date 2 with regard to the Additional
     Premises, and from and after the respective commencement date of this Lease
     with regard to any other space in the Building leased by Lessee pursuant to
     this Lease, Lessor shall provide the following utilities and services:

                  (i) Hot  and  cold  water  and  lavatory  supplies,  it  being
understood  and agreed that hot and cold water shall be furnished by Lessor only

                  (iii) Cleaning and char  services,  as specified in Exhibit E,
after normal business hours,  Monday through Friday of each week,  except on the
holidays  listed in  subparagraph  (iv) below (and with regard to the Additional
Premises, only from after that point in time at which Lessee commences to occupy
the Additional Premises for its business purposes).

                  (iv)  Heat and  air-conditioning  in  season,  Monday  through
Friday from 8:00 a.m. to 8:00 p.m., and on Saturday from 9:00 a.m. to 6:00 p.m.,
except for the following holidays:  New Year's Day, Martin Luther King, Jr. Day,
Presidents' Day, Memorial Day, Fourth of July, Labor Day, Columbus Day, Veterans

preceding  sentence at Lessee's  expense.  provided  Lessee gives Lessor  notice
prior to 1:00 p.m. on a business day in the case of after-hours  service on that
business day and prior to 3:00 p.m. on the immediately preceding business day in
the case of  after-hours  service on a Saturday,  a Sunday or a holiday.  Lessor
shall charge Lessee for said after-hours services the same rate it charges other
tenants, which is $35.00 per hour on the date of execution of this Lease. Lessor
reserves the right,  in its sole  discretion,  to increase the hourly charge for
said  after-hours  service  from  time to time,  with any  such  increase  being
reasonably  related to actual cost increases  incurred by Lessor to deliver such
services,  but in no event shall the rate per hour  charged  Lessee be more than
the rate per hour  charged  other  tenants.  In the event  the same  after-hours
service is also  requested  by other  tenants of the  Building  in  addition  to
Lessee,  the charge therefor to each tenant requesting such after-hours  service
shall be prorated among all requesting  tenants based upon the respective square
footages  of  each  of the  demised  premises  of the  tenants  requesting  such
after-hours service.

                  (v)  Maintenance,  painting and electric  lighting service for
all public areas and special service areas in the Building.

                  (vi) Security comparable to other first-class office buildings

                  (vii) Electricity and proper electrical  facilities to furnish
sufficient electricity for equipment of Lessee installed pursuant to the Section
of this Lease entitled, "LESSEE'S EQUIPMENT."

         (B) In the event any  public  utility  supplying  energy  requires,  or
government  law,  regulation,  executive or  administrative  order  results in a
requirement,  that Lessor or Lessee must reduce, or maintain at a certain level,
the  consumption  of  electricity  for the Demised  Premises or Building,  which
affects the heating,  air-conditioning,  lighting,  or hours of operation of the
Demised  Premises or Building,  Lessor and Lessee shall each adhere to and abide
by said laws, regulations or executive orders without any reduction in rent.

         (C)  Lessor's  inability  to  furnish,  to any  extent,  these  defined
services,  or any cessation  thereof,  resulting  from,  but not limited to, any
causes including entry for inspections,  repairs, alterations,  improvements and
installations by Lessor,  its agents,  employees or contractors  pursuant to the
Section  of  this  Lease   entitled   "ENTRY  FOR   INSPECTIONS,   REPAIRS   AND
INSTALLATION," or from renovation, redecoration or rehabilitation of any area of
the Building,  including the lobby,  or any of the  surrounding  public  spaces,
shall not render Lessor liable for damages to either person or property,  nor be
construed  as an eviction  of Lessee,  nor work an  abatement  of any portion of
rent, nor relieve Lessee from  fulfillment of any covenant or agreement  hereof.
Should any of the Building equipment or machinery cease to function properly for
any cause,  Lessor shall use  reasonable  diligence to repair the same promptly,
but,  except as provided for in  Subsection  (D) below of this  Section,  Lessee
shall  have no claim  for  damages  or for a rebate  of any  portion  of rent on
account of any  interruptions  in any services  occasioned  thereby or resulting
therefrom.

         (D)  Notwithstanding  the  provisions of  Subsection  (C) above of this
Section,  where (i) such  failure to provide  such  services  causes the Demised
Premises to be not reasonably usable for Lessee's business purposes, (ii) Lessee
substantially   ceases   operation  of  its  business  therein  and  (iii)  such
circumstances  continue for at least thirty (30)  consecutive days following the
date on which Lessee  gives Lessor  written  notice of such  circumstances,  or,
where the failure of service is a failure or  electrical  power to the Building,
not caused by a general power failure  affecting the surrounding  area, and such
circumstances continue for fifteen (15) consecutive days, then commencing on the
date which is  thirty-one  (31) days (or sixteen  (16) days in the event of such
power  failure,  as  applicable)  after  Lessor  has  received  such  notice and
continuing  until the earlier of (a) the date Lessee is no longer  substantially
not using the Demised  Premises for the  operation of its  business,  or (b) the
date on which the Demised  Premises  are again  reasonably  usable for  Lessee's
business purposes,  Lessee shall be entitled to an abatement of Monthly Rent and
additional rent arising from increases in Operating  Expenses,  Operating Costs,
and/or Real Estate Tax es. However,  in the event Lessor denies Lessee access to
the Demised Premises during such initial thirty (30) day period (or fifteen (15)
day period,  as applicable),  such abatement shall also apply during such period
in which Lessee has been denied access by Lessor.

subtenants,  licensees,  contractors,  servants,  employees and visitors,  or by
individuals and persons making  deliveries to or from the Demised Premises shall
be repaired by Lessor at the sole expense of Lessee. Payment of the cost of such
repairs by Lessee shall be due as additional  rent with the next  installment of
Monthly  Rent after Lessee  receives a bill for such  repairs from Lessor.  This
provision  shall not be in  limitation  of any other rights and  remedies  which
Lessor has or may have in such circumstances.

21.      ENTRY FOR INSPECTIONS, REPAIRS AND INSTALLATIONS

         (A) Lessee shall permit Lessor, or its agent, employees or contractors,
without notice to Lessee,  to enter the Demised Premises at all reasonable times
and in a reasonable  manner,  without  charge to Lessor or diminution of Monthly
Rent payable by Lessee, to examine,  inspect and protect the Building, and, upon
one (1) day written  notice,  to make such  repairs as in the judgment of Lessor
may be deemed  necessary to maintain or protect the Building,  or to exhibit the
Demised Premises to prospective tenants during the last one hundred twenty (120)
days of the term of this Lease.  Lessor shall use reasonable efforts to minimize
interference to Lessee's  business when making repairs,  but Lessor shall not be
required  to perform  the  repairs at a time other than  during  normal  working
hours.

         (B) In the event of an emergency, Lessor may enter the Demised Premises
without notice and make whatever repairs are necessary to protect the Building.

(C) Lessee shall permit Lessor, or its agents, employees or contractors, upon no
less than ten (10) days prior  written  notice to Lessee,  to enter the  Demised
Premises at  reasonable  times and in a  reasonable  manner,  without  charge to
Lessor or  diminution of Monthly Rent payable by Lessee,  to make  installations
related to the  construction  of  pre-occupancy  tenant work being  performed by
Lessor for other  tenants of the  Building,  to make  repairs,  alterations  and
improvements  arising due to repairs,  alterations and improvements to any areas
adjoining the Demised Premises, to erect, use and maintain pipes and conduits in
and through the Demised  Premises,  or to make  installations,  improvements and
repairs to utility  services  of the  Building  located in or about the  Demised
Premises.  Lessor shall use reasonable  efforts to minimize  interferences  with
Lessee's business operations, and, except in an emergency, will seek to schedule
its activities so as to reasonably accommodate Lessee undertaking its normal and
ordinary business operations.  If, except in the case of an emergency,  Lessee's
business operations cannot be reasonably  accommodated so as to permit Lessor to
undertake such work during Lessee's normal working hours, Monday through Friday,
then Lessor will undertake  such work beyond those normal working hours.  Lessor
shall always be  permitted  to undertake  such work after 8:00 p.m. on weekdays,
after  6:00  p.m.  on  Saturdays  and  all day on  Sundays  and  legal  holidays
recognized under this Lease.


22.      INSURANCE RATING

         Lessee shall not conduct or permit to be  conducted  any  activity,  or
place any  equipment  or  property in or about the  Demised  Premises  that will
increase in any way the rate of All Risk Coverage  insurance or other  insurance
on  the  Building,  unless  consented  to by  Lessor.  Lessor's  consent  may be
conditioned  upon Lessee's  payment of any costs arising  directly or indirectly
from such increase.  If any increase in the rate of All Risk Coverage  insurance
or other insurance on the Building is stated by any insurance  company or by the
applicable Insurance Rating Bureau to be due to Lessee's activity,  equipment or
property in or about the Demised  Premises,  said statement  shall be conclusive
evidence  that the increase in such rate is due to such  activity,  equipment or
property.  In such case,  Lessor shall notify  Lessee of -such fact and,  unless
Lessee's  ceases such  activity  within five (5) business days after the date of
receipt by Lessee of Lessor's notice,  Lessee shall be liable for such increase.
Any such rate  increase  and related  costs  incurred by Lessor  shall be deemed
additional  rent due and payable by Lessee to Lessor upon receipt by Lessee of a
written  statement of the rate  increase and costs.  Lessee may contest,  at its
sole cost and expense,  any  insurance  rate  increase,  provided such action by
Lessee will not adversely affect the insurance coverage of Lessor.

any  and all  liability,  damage,  expense,  cause  of  action,  suits,  claims,

in and on the Demised Premises,  or upon any adjoining sidewalks or public areas
of the  Building,  which arise out of the act,  failure to act or  negligence of
Lessee, its subtenants, licensees, agents or employees.

equipment,  furniture,  and all other personal property in and about the Demised

         (C) Lessor and Lessee  hereby  release  each other and waive any claims
they may have  against  the other for loss or  damage to the  Building,  Demised
Premises,  tenant  improvements,  fixtures,  equipment and/or any other personal
property  arising  from a risk  insured  against  under  the All  Risk  Coverage
insurance  policies to be carried by Lessor and Lessee,  as required above, even
though such loss or damage was caused by the negligence of Lessor, or Lessee, or
their respective  agents or employees (or any combination  thereof),  except for
the amount of the deductible under said policies.

         (D) Lessor and Lessee agree to obtain and maintain  throughout the term
of this  Lease  endorsements  to their  respective  All Risk  Coverage  policies
waiving the right of subrogation of their insurance  companies against the other

herein,  nothing  contained in this Lease shall relieve  Lessor or Lessee of any
liability to each other or to their  insurance  carriers  which Lessor or Lessee
may have under law or the provisions of this Lease in connection with any damage

furniture, and all other personal property, by fire or other casualty.

required to carry and maintain or cause to be carried or maintained  pursuant to

responsible  insurance  company,  licensed  to do  business  in the  District of
Columbia. Lessee's public liability and All Risk Coverage insurance policies and

additional  insured  and shall also  contain a  provision  by which the  insurer
agrees that such  policy  shall not be canceled  except  after  thirty (30) days

failure of Lessee to pay any premium due  thereunder,  in which case the insurer
shall  only be  required  to  provide to Lessor no less than ten (10) days prior
written  notice of  cancellation.  Lessee  agrees to provide to Lessor  prior to

additional rent, payable upon Lessor's demand.

     business invitees, licensees, customers, clients, family members, guests or

     the Demised  Premises and the Building at the sole risk of said parties and
     Lessor  shall not be liable to any such  person or party for any damage to,

29       DAMAGE TO THE BUILDING AND/OR THE DEMISED PREMISES

(A) If the Demised Premises is damaged by fire,  casualty or other event insured
against by Lessor's All Risk Coverage  insurance  policy  covering the Building,
and the Demised Premises can be fully repaired,  in the professional  opinion of
an  independent  registered  architect  licensed to practice in the  District of
Columbia selected by Lessor,  within 180 days from the date of the insured fire,
casualty or other event, Lessor, at Lessor's expense,  shall repair such damage,
provided,  however,  Lessor shall have no obligation to repair any damage to, or
to replace,  (i) tenant  improvements in and about the Demised Premises that are
of a non building  standard  nature  specified in Exhibit B or are of a building
standard  nature,  but in excess of the level or quantity  of building  standard
improvements and fixtures specified in Exhibit B, (H) all of Lessee's equipment,
furniture,  and all other personal  property in and about the Demised  Premises,
and  (iii)  any  other  property  located  in the  Demised  Premises.  Except as
otherwise   provided  herein,   if  the  entire  Demised  Premises  is  rendered
untenantable  by reason of the  insured  fire,  casualty  or other  event,  then
Monthly Rent shall abate for the period from the date of such damage to the date
when Lessor has completed  repairs to the Demised  Premises as specified  above,
and if only a portion of the Demised Premises is so rendered untenantable,  then
Monthly Rent shall abate for such period in the proportion which the area of the
portion of the Demised Premises so rendered untenantable bears to the total area
of the Demised  Premises,  provided,  however,  if,  prior to the date when such
repairs  have been  completed,  any portion of the  Demised  Premises so damaged
shall be  rendered  tenantable  and shall be used or  occupied  by Lessee or any
person  claiming  through or under Lessee,  then the amount by which the Monthly
Rent shall abate shall be equitably  apportioned for the period from the date of
any such use or  occupancy  to the date  when such  repairs  are  completed.  No
compensation  or claim or reduction of rent will be allowed or paid by Lessor by
reason of  inconvenience,  annoyance,  or injury to  business  arising  from the
necessity  of repairing  the Demised  Premises or any portion of the Building of
which they are a part.


         (B)  Notwithstanding  the  foregoing,  if, within sixty (60) days after
such fire or casualty, whether prior to or during the term of this Lease, (i) an
independent  registered  architect  licensed  to  practice  in the  District  of
Columbia selected by Lessor determines in his/her/its  professional opinion that
the Demised  Premises is so damaged  that the Demised  Premises  cannot be fully
repaired  within  180  days  from  the  date  the  damage  occurred,  or (ii) an
independent  registered  architect  licensed  to  practice  in the  District  of
Columbia selected by Lessor determines in his/her/its  professional opinion that
the Building is so damaged by fire or other casualty insured against by Lessor's
All Risk  Coverage  policy  that  substantial  repair or  reconstruction  of the
Building  shall be required  (whether or not the Demised  Premises is damaged or
rendered untenantable), then, in any of such events:

                  (a) Lessor,  at its option,  may give to Lessee,  within sixty
(60) days of a determination made under (i) or (ii) above of this Subsection (B)
as applicable a thirty (30) day notice of  termination of this Lease and, in the
event that such notice is given, this Lease shall terminate  (whether or not the
term shall have commenced) upon the expiration of such thirty (30) days with the
same effect as if the date of  expiration of such thirty (30) days were the date
definitely  fixed  for  the  expiration  of the  term  of  this  Lease,  and the
then-applicable Monthly Rent shall be apportioned as of such date, including any
rent abatement as provided above.

                  (b)  Provided  Lessor,  under  the  terms  of the  instruments
documenting from time to time financing secured by the Building, is not deprived
of the use of  insurance  proceeds as a result of the  granting to a tenant of a
right to terminate its lease in the case of a fire or casualty,  or do not cause
a diminution in the amount of insurance  proceeds as a result of the granting to
a tenant of such right, Lessee shall have the right to terminate this Lease upon
thirty (30) days' prior written notice to Lessor, said notice to be given within
sixty (60) days after the date either  determination  under (i) or (ii) above of
this  Subsection  (B) is rendered.  In the event Lessee gives such notice,  this
Lease shall  terminate  (whether or not the term shall have  commenced) upon the
expiration  of such  thirty  (30)  days  with the same  effect as if the date of
expiration  of such  thirty  (30)  days  were  the  date  definitely  fixed  for
expiration of the term of the Lease, and the then applicable  Monthly Rent shall
be  apportioned  as of such date,  including  any rent  abatement as provided in
Subsection (A) above of this Section.

                  (C) Except where Lessee shall have the right to terminate  the
term of this  Lease  under  Subsection  (B) of this  Section,  if Lessor has not
elected to terminate this Lease, and thus thereafter becomes obligated to repair
and/or  reconstruct  the  Demised  Premises  and the  Building,  then Lessee may
terminate  the term of this  Lease in the event  the  Demised  Premises  are not
substantially  restored to the extent of Lessor's  obligations  under Subsection
(A) of this Section  within two hundred  seventy (270) days from the date of the
fire or casualty.  To exercise this right to  terminate,  Lessee must deliver to
Lessor written notice of Lessee's  election to terminate not later than five (5)
business days after the expiration of the two hundred seventy (270) day period.


         (D)  For  the  purposes  of  this  Section  of  the  Lease,   the  term
"untenantable" means not reasonably usable by Lessee for its business purposes.


30.       DEFAULT OF LESSEE

This Lease shall,  at the,  option of Lessor,  cease and terminate if (i) Lessee
     fails  to pay  rent,  including  any  installment  of  Monthly  Rent or any
     additional rent, although no legal or formal demand has been made, and such
     failure to pay rent  continues  for a period of ten (10) days after written
     notice  addressed  to Lessee has been  delivered  by Lessor to the  Demised
     Premises,  or (ii)  Lessee  violates  or fails to perform  any of the other
     conditions,  covenants or agreements of this Lease made by Lessee,  and any
     violation  or failure  to perform  any of those  conditions,  covenants  or
     agreements  continues for a period of thirty (30) days after written notice
     thereof  has been  delivered  by Lessor to Lessee,  or, in cases  where the
     violation  or failure to perform  cannot be  corrected  within  thirty (30)
     days,  Lessee does not begin to correct the violation or failure to perform
     within  thirty (30) days after  receiving  Lessor's  written  notice and/or
     Lessee  thereafter  does  not  diligently  pursue  the  correction  of  the
     violation or failure to perform.  Any said  violation or failure to perform
     or to pay any rent, if left uncorrected, shall operate as a notice to quit,
     any  further  notice to quit or notice of  Lessor's  intention  to re-enter
     being hereby  expressly  waived.  Lessor may thereafter  proceed to recover
     possession  under  and by  virtue  of the  provisions  of the  laws  of the
     jurisdiction in which the Building is located or by such other proceedings,
     including re-entry and possession,  as may be applicable.  If Lessor elects
     to terminate this Lease,  everything herein contained on the part of Lessor
     to be done and  performed  shall cease  without  prejudice  to the right of
     Lessor to recover from Lessee all rent  accruing up to and through the date
     of  termination  of this Lease or the date of recovery of possession of the
     Demised  Premises  by  Lessor,  whichever  is later.  Should  this Lease be
     terminated  before  the  expiration  of the term of this Lease by reason of
     Lessee's default as hereinabove provided, or if Lessee abandons the Demised
     Premises  before the  expiration or  termination of the term of this Lease,
     the  Demised  Premises  may be relet by Lessor  for such rent and upon such
     terms as are not  unreasonable  under the  circumstances,  and, if the full
     rent hereinabove provided is not realized by Lessor, Lessee shall be liable
     for  all  damages  sustained  by  Lessor,  including,  without  limitation,
     deficiency  in  rent,  reasonable  attorneys'  fees,  brokerage  fees,  and
     expenses of placing the Demised Premises in first-class rentable condition.
     Any damage or loss of rent  sustained by Lessor  (including  any deficiency
     between the rent  reserved  pursuant to the reletting and the rent reserved
     under this Lease, accelerated to the date of reletting) may be recovered by
     Lessor, at Lessor's 'option,  at the time of the reletting,  or in separate
     actions, from time to time. as said damage shall have been made more easily
     ascertainable  by successive  relettings,  or, at Lessor's  option,  may be
     deferred until the expiration of the term of this Lease, in which event the
     cause of  action  shall not be  deemed  to have  accrued  until the date of
     expiration of said term. The provisions  contained in this Section shall be
     in addition to and shall not prevent the  enforcement  of any claim  Lessor
     may have against  Lessee for  anticipatory  breach of the unexpired term of
     this Lease.


31.       REPEATED DEFAULTS

         If Lessee has  committed a Material  Default more than twice during any
twelve  (12) month  period  during the term of this  Lease,  then,  at  Lessor's
election, Lessee shall not have any right to cure such repeated failure default,
the terms and  conditions  of the  Section of this Lease  entitled,  "DEFAULT OF
LESSEE," notwithstanding.  In the event of Lessor's election not to allow a cure
of a repeated default.  Lessor shall have all of the rights provided for in that
Section of this Lease for an uncured default.

32.      WAIVER

If Lessor  institutes legal or administrative  proceedings  against Lessee and a
compromise or settlement thereof is made, the same shall not constitute a waiver
of Lessee's obligations to comply with any covenant, agreement or condition, nor
of any of Lessor's  rights  hereunder.  No waiver by Lessor of any breach of any
covenant,   condition,  or  agreement  specified  herein  shall  operate  as  an
invalidation or as a continual  waiver of such covenant,  condition or agreement
itself, or of any subsequent breach thereof.  No payment by Lessee or receipt by
Lessor (or any party  designated by Lessor to receive any payments of rent) of a
lesser  amount  than the amount of rent due  Lessor  shall be deemed to be other
than  payment  on account of the  earliest  stipulated  rent.  In  addition,  no
endorsement or statement on any check or letter accompanying a check for payment
of such  rent be  deemed  an  accord  and  satisfaction.  Lessor,  or any  party
designated  by Lessor,  may accept such check or payment  without  prejudice  to
Lessor's right to recover the balance of such rent or to pursue any other remedy
provided for in this Lease or in the governing law of the  jurisdiction in which
the Building is located.  No re-entry by Lessor,  and no acceptance by Lessor of
keys from Lessee, shall be considered an acceptance of a surrender of the Lease.


33.      SUBORDINATION

         (A) This Lease is subject  and  subordinate  to the lien of all and any
mortgages (which term "mortgages"  shall include both construction and permanent
financing  and shall include  deeds of trust and similar  security  instruments)
which  may now or  hereafter  encumber  or  otherwise  affect  the  real  estate
(including  the  Building) of which the Demised  Premises is a part, or Lessor's
leasehold   interest  therein,   and  to  all  and  any  renewals,   extensions,
modifications,  recastings or  refinancings  thereof.  In  confirmation  of such
subordination, Lessee shall. at Lessor's request, promptly execute any requisite
or appropriate  certificate or other  document.  Lessee hereby  constitutes  and
appoints Lessor as Lessee's attorney-in-fact to execute any such certificate for
or on behalf of Lessee if Lessee does not execute said  certificate  or document
within ten (10) business days after receipt thereof.

         (B) Lessee agrees that in the event any proceedings are brought for the
foreclosure of any such  mortgage,  Lessee shall attorn to the purchaser at such
foreclosure  sale and recognize such purchaser as the party identified as Lessor
under this  Lease,  provided  that such party shall have no  obligations  for or
responsibility  to  correct  any  past  violations  or  failures  of  the  party
previously  identified as Lessor. Lessee waives the provisions of any statute or
rule of law,  now or  hereafter  in  effect,  which may give or  purport to give
Lessee any right to terminate or otherwise  adversely  affect this Lease and the
obligations  of  Lessee  hereunder  in  the  event  that  any  such  foreclosure
proceeding is prosecuted or completed.

         (C) Notwithstanding Lessee's agreement to subordinate this Lease to any
mortgages as set forth in Subsection  (A) of this Section,  Lessor agrees to the
following:

                   (i) Subject to the provisions of Subsection (C)(iii) below of
this  Section,  Lessor  shall  have  the  affirmative  obligation  to  obtain  a
nondisturbance  agreement for Lessee (a) from the holder of the current mortgage
secured by the  Building  and the Land and (b) from the holder of any  successor
mortgage placed by Lessor in calendar years 1997, 1998 and 1999, provided Lessee
is not, at the time Lessor seeks to place a new mortgage secured by the Building
and/or the Land during the term of this Lease,  in default of any  obligation or
covenant of Lessee  specified  in this Lease after any period to cure or correct
such default specified in this Lease has expired.

         (ii) Lessor  shall use its  commercially  reasonable  efforts to obtain
(but without any  obligation  to pay a premium for) a  nondisturbance  agreement
from any holder of any successive  mortgage  secured by the Building  and/or the
Land placed by Lessor after calendar year 1999.

         (iii) The form of nondisturbance  agreement shall either be in the form
attached  as  Exhibit F, or in the usual and  customary  form of any holder of a
mortgage, upon terms reasonably acceptable to Lessee. The terms of such holder's
form shall be deemed reasonable to Lessee if its terms do not in any substantive
manner alter,  change or modify any of the rights and benefits granted to Lessee
by this  Lease,  and  specifically  do not cause any change or  modification  in
Lessee's rent  obligations as fixed by the provisions of this Lease.  Lessee may
not require as a condition to its acceptance of any form of nondisturbance  that
the  holder  of such  mortgage  (a)  recognize  such  nondisturbance  protection
afforded to Lessee at any time that the holder  becomes  vested with  control of
the Building  and/or the Land by  foreclosure or otherwise and Lessee is then in
default  under  this  Lease  and  notice  thereof  has  been  given  and cure or
correction  of such  noted  default  has not been  made by  Lessee,  (b) cure or
correct any default of Lessor  arising prior to the date that the holder of such
mortgage becomes vested with -control over the Building and/or the Land, whether
by foreclosure or otherwise,  or (c) become  responsible  for any monies paid by
Lessee to Lessor in advance of when  required to be paid pursuant to this Lease,
where such payment  occurs prior to the date that the holder of such mortgage is
vested with control over the Building,  whether by foreclosure or otherwise. Any
nondisturbance  agreement  shall  specifically  provide  that Lessee will not be
disturbed in its possession of the Demised  Premises or of its rights under this
Lease by the holder of such  mortgage  in the event of a  foreclosure,  provided
however  Lessee is then not in default of its  obligations  and covenants  under
this  Lease.  after the  giving  of  applicable  notice  and the  expiration  of
applicable periods to cure or correct without cure or correction being made.

         (D) If the  Building,  the Demised  Premises  or any part  respectively
thereof is at any time subject to a mortgage or a deed of trust or other similar
instrument, and this Lease or the rents are assigned to such mortgagee,  trustee
or beneficiary,  and Lessee is given written notice thereof,  including the post
office  address of such  assignee,  then Lessee may not terminate this Lease for
any  default  on the part of  Lessor  without  first  giving  written  notice by
certified or  registered  mail,  return  receipt  requested,  to such  Assignee,
Attention:  Mortgage  Loan  Department.  The notice shall specify the default in
reasonable  detail,  and afford such assignee a reasonable  opportunity  to make
performance, at its election, for and on behalf of Lessor.


34.      CONDEMNATION

                  (A) If the whole or a substantial part of the Demised Premises
or the  Building  is  condemned  or  acquired  in  lieu of  condemnation  by any
governmental  authority for any public or quasi-public use or purpose,  then the
term of this Lease shall cease and  terminate as of the date when title vests in
such  governmental  authority.  Lessee shall have no claim against Lessor or the
condemning  authority for any portion of the amount of the condemnation award or
settlement that Lessee claims as its damages  arising from such  condemnation or
acquisition,  or for the value of any  unexpired  term of the Lease.  Lessee may
make a separate claim against the condemning  authority for a separate award for
the value of any of Lessee's tangible personal property and trade fixtures,  for
moving  and   relocation   expenses  and  for  such  business   damages   and/or
consequential  damages  as may be allowed  by law,  provided  the same shall not
diminish the amount of Lessor's award.


         (B) If  less  than  a  substantial  part  of the  Demised  Premises  is
condemned or acquired in lieu of condemnation by any governmental  authority for
any public or quasi-public use or purpose,  the rent shall be equitably adjusted
on the date when title vests in such governmental  authority and the Lease shall
otherwise  continue in full force and effect.  For purposes of this  Section,  a
"substantial  part of the Demised  Premises"  shall be  considered  to have been
taken if twenty-five percent (25 %) or more of the Demised Premises is condemned
or acquired in lieu of condemnation,  or if less than twenty-five percent (25 %)
of the Demised  Premises is taken and the portion of the Demised  Premises taken
renders the entire  Demised  Premises  untenantable  for the conduct of Lessee's
business..

(C)  If twenty-five  percent (25%) or more of the Building is condemned (whether
     or not the Demised Premises shall have been condemned) and Lessor elects to

and regulations attached hereto as Exhibit C and such other reasonable rules and
regulations as may be promulgated  from time to time by Lessor for the operation
and maintenance of the Building,  provided a copy thereof is sent to Lessee. Any
failure to comply  with any rule or  regulation  may become a basis  under which
Lessor  may claim a  default  by  Lessee,  after  the  giving of notice  and the
expiration  of the thirty  (30) day period to cure or  correct  afforded  by the
Section of this Lease entitled  "DEFAULT OF LESSEE."  Nothing  contained in this

shall  constitute  additional  rent  hereunder  due and  payable by Lessee  upon
receipt of a written statement of costs from Lessor.  The making of such payment
or the doing of such act by  Lessor  shall  not  operate  as a waiver or cure of
Lessee's default.  nor shall it prevent Lessor from the pursuit of any remedy to
which Lessor would otherwise be entitled.

be paid by Lessee pursuant to this Lease which are not paid by Lessee within ten

equal to two (2)  percentage  points  above the then base rate of  interest  (or
comparable  rate of  interest)  per  annum  as fixed  by a  federally  chartered
financial  institution as reasonably selected by Lessor,  accruing from the date
such  installment  or  payment  became  due and  payable  to the date of payment
thereof by Lessee. As and to the extent that no time for payment is specified in
this Lease with regard to any charge or payment,  such  payment  shall be deemed
due an payable to Lessor within  thirty (30) days of receipt of Lessor's  notice
to Lessee  requesting  payment,  with any late charge rising ten (10) days after
the expiration of such payment period. Such interest shall constitute additional
rent due and  payable  to  Lessor  by  Lessee  upon the date of  payment  of the
delinquent payment referenced above.

Nothing  contained  in this  Lease  shall be  deemed  or  construed  to create a

              CONDITIONAL TERMINATION OF LEASE AGREEMENT

         This  Conditional  Termination of Lease Agreement (the  "Agreement") is
made and entered  into this 31st day of March,  1997,  by and between  George H.
Beuchert,  Jr., Trustee,  Thomas J. Egan, Trustee, Oliver T. Carr, Jr., Trustee,
William Joseph H. Smith,  Trustee, and The Kiplinger  Washington Editors,  Inc.,
Trustee,  acting collectively as trustees on behalf of the beneficial owner, The
Greystone  Square 127 Associates,  a District of Columbia  limited  partnership,
collectively, hereinafter referred to as "Lessor," and Putnam, Hayes & Bartlett,
Inc., a Massachusetts corporation, hereinafter referred to as "Lessee."


                                                    WITNESSETH:

         WHEREAS,  by Lease Agreement dated the 8th day of July, 1988 as amended
by  Addendum  No. 1 to Lease  Agreement  dated  November  3,  1988  (hereinafter
referred to as the "Lease"), Lessor leased to Lessee approximately 36,265 square
feet of rentable  area on the fifth  (5th) and sixth (6th)  floors of the office
building  situated  at 1776 Eye  Street,  N.W.,  Washington,  D.C.  20006  (such
building  hereinafter  referred  to as the  "Building"  and said  rentable  area
hereinafter referred to as the "Demised Premises");

         WHEREAS,  Lessor and Lessee  have  agreed to  provide  for the  earlier
termination of the term of the Lease based upon (i) Lessee's  agreement to enter
into a new lease with Lessor for the  Demised  Premises  and certain  additional
premises  located on the fifth  (5th)  floor of the  Building  (the  "Additional
Premises"), and (ii) the terms and conditions of this Agreement set forth below;

         WHEREAS,  Lessor and Lessee  desire to  formally  reflect the terms and
conditions under which the Lease will be terminated;

         NOW, THEREFORE,  in consideration of mutual covenants contained herein,
and  other  good  and  valuable  consideration,   receipt  of  which  is  hereby
acknowledged, the parties agree as follows:

         1. Lessor and Lessee have as of the date of this Agreement entered into
a lease  dated  the 31st day of  March,  1997 (the  "Successor  Lease")  for the
leasing by Lessee of the Demised Premises and the Additional Premises.

         2. The Lease shall be and is hereby  terminated  effective  as of 11:59
P.M.  on  December  31,  1996,  (such day being  hereinafter  referred to as the
"Termination Date").  Except as otherwise provided in this Agreement,  as of the
Termination Date, the Lease shall be deemed to be of no further force and effect
thereafter,  subject to the  conditions  otherwise set forth herein.  Lessor and
Lessee, as of the Termination Date, shall be and are hereby equally released and
discharged from any obligations to observe the terms and conditions of the Lease
accruing after the Termination  Date;  provided,  however,  that Lessee complies
with the conditions otherwise set forth herein.



<PAGE>


         3. (A) Lessee  shall remain  fully  obligated  for all Monthly Rent (as
defined in the Lease) accruing  through the Termination  Date under the terms of
the Lease. To the extent that Lessee has paid to Lessor,  pursuant to the Lease,
Monthly  Rent (as defined in the Lease) in excess of Monthly  Rent 1 (as defined
in the Successor  Lease) due under the  Successor  Lease for any period from and
after January 1, 1997, then from and after January 1, 1997,  Lessor shall credit
to Lessee an  amount-equal  to the difference  between (i) the amount of Monthly
Rent actually paid by Lessee for the Demised Premises  pursuant to the Lease and
(ii) the amount of Monthly Rent 1 which  otherwise  would have been paid for the
Demised Premises pursuant to the Successor Lease, with such credit being applied
to the Monthly  Rent 1 first due from  Lessee  under the  Successor  Lease until
exhausted.

                  (B) Lessee shall remain  obligated  for the full amount of its
proportionate  share of increases in Operating  Expenses and Operating Costs, as
defined and set forth in the Section of the Lease  entitled  "RENTAL  ESCALATION
FOR  INCREASES IN EXPENSES,"  accruing with respect to the entire  calendar year
1996.

         4. All notices or other  communications to be delivered to Lessee under
the Lease or this Agreement,  after the Termination Date, shall be delivered to:
(A) if to  Lessor,  c/o  Carr  Real  Estate  Services,  Inc.,  Suite  700,  1700
Pennsylvania  Avenue, N.W.,  Washington,  D.C. 20006; and (B) if to Lessee, at 1
Memorial Drive, Cambridge,  Massachusetts 02142,  Attention:  Corporate Counsel,
with a courtesy copy sent to Suite 600, 1776 Eye Street,  N.W.,  Washington,  DC
20006.  Lessor's  failure  to  deliver a  courtesy  copy of any  notice or other
communication  to the  Demised  Premises  shall  not  serve to void or waive the
validity of any notice or  communications,  if such notice or communications was
otherwise  properly delivered to the principal address of Lessor noted alone for
receipt  of notices  and other  communications  by Lessee.  The party to receive
notices and the place  notices are to be sent for either Lessor or Lessee may be
changed by notice given pursuant to the provisions of this Section.

         5.  Lessor  and  Lessee  agree  to waive  trial by jury in any  action,
proceeding  or  counterclaim  brought by either party  against the other or with
respect to any matter  whatsoever  arising out of or in any way  connected  with
this Agreement.

         6. The provisions of this Agreement  shall be binding upon and inure to
the benefit of the parties  hereto and each of their  respective  successors and
assigns.

         7.  Notwithstanding  anything  to the  contrary in this  Agreement,  if
Lessee  cancels  the  Successor  Lease  in  accordance  with the  provisions  of
Subsections  (D) or (E) of the Section of the Successor  Lease entitled  "TERM,"
then this Agreement and the termination of the Lease intended to be accomplished
by this  Agreement  shall be deemed null and void,  and of no further  force and
effect between Lessor and Lessee,  as of the date of  cancellation  by Lessee of
the Successor  Lease,  except that this Agreement shall be deemed to survive for
the limited purpose of confirming Lessee's agreement and recognition that Lessee
shall be liable to Lessor for the payment of any rent  accruing  under the Lease
from and after January 1, 1997,  subject however to the recognition by Lessor of
a credit toward  Lessee's  obligation for the payment of rent under the Lease in
the amount of rent paid to Lessor as "Monthly  Rent" under the Successor  Lease.
The  cancellation  of the Successor Lease shall be deemed without further action
to revive the Lease, as if it had never been  terminated by this Agreement,  and
the Lease shall be deemed to continue in full force and effect. Lessee shall pay
to Lessor any  underpayment  of Monthly Rent,  Operating  Expenses and Operating
Costs or both which are due and owing  under the Lease  within  thirty (30) days
after  receipt of notice  from  Lessor of the amount of rent due and owing under
the Lease,  subject to any credit for  "Monthly  Rent" paid under the  Successor
Lease.

         IN WITNESS  WHEREOF,  the parties  hereto have caused this  Conditional
Termination  of Lease  Agreement to be signed and sealed in their names by their
duly authorized representatives,  intending to be legally bound by its terms and
provisions.

     shall promptly  reimburse to Lessee  appropriate  amounts  requested by the
     invoices.  In no event,  however,  shall  Lessor be  obligated to reimburse
     Lessee  for any  amount if such  amount  individually  or in the  aggregate
     exceeds the total amount of the Alternate Expansion Space One Allowance and
     Mandatory Expansion Premises Allowance.

          (iii)   Lessee must submit all invoices for  reimbursement  no earlier
                  than  December  1, 1999 and no later than the last date of the
                  Fit  Out  Period,  and  Lessor  shall  have no  obligation  to
                  reimburse Lessee for any invoices  submitted prior to December
                  1, 1999 or after the last date of the Fit Out  Period.  In the
                  event that Lessee has not  requested  release of all monies in
                  the  Alternate  Expansion  Space One  Allowance  and Mandatory
                  Expansion  Premises  Allowance by the last date of the Fit Out
                  Period,  then any remaining monies shall be credited by Lessor
                  to rent next due and owing by Lessee under the Lease.

          (iv)    Notwithstanding the foregoing, Lessor shall have no obligation
                  to  reimburse  Lessee or to credit any  unused  portion of the
                  Alternate   Expansion   Space  One   Allowance  and  Mandatory
                  Expansion Premises Allowance to Monthly Rent due and owing, if
                  Lessee fails to comply with the terms and  conditions  of this
                  Section of this  Addendum  No. 1, or if Lessee is in  Material
                  Default  of the  Lease,  whether  at the time  Lessee  makes a
                  request for  reimbursement or at any time thereafter up to and
                  including  the date  Lessor  makes any such  reimbursement  to
                  Lessee.

claims for brokerage or other commission(s) arising from or out of any breach of
the foregoing  representation and warranty by Lessor. Lessee shall indemnify and
hold Lessor harmless from and against all claim or claims for brokerage or other
commission(s)  arising  from  or out  of my  breach  of  any  of  the  foregoing
representations  and warranties by Lessee,  and additionally  from or out or any
conflicting or competing  claims made by Lessee's  Brokers as to any entitlement
and/or  amount of commission  due to either of Lessee's  Brokers and relating to
this transaction.

         (B) Lessor has  designated  as of the date  first  hereinabove  stated,
Hagner Management Corporation,  its manager of operations, as its agent pursuant
to the  provisions of the second (2nd)  paragraph of the Section of the Original
Lease entitled "BROKER AND AGENT."

         8.       PARKING

         (A) As of the Alternate  Expansion Space One Commencement  Date, Lessee
shall be entitled to two (2) additional parking contracts,  under the same terms

"PARKING,"  provided  that the period  for action by Lessee  shall be sixty (60)
days after the Alternate Expansion Space One.

         (B) As of the Mandatory  Expansion  Premises  Commencement Date, Lessee

Mandatory Expansion Premises Commencement Date.

         (C) As of the applicable  Expansion  Space  Commencement  Date,  Lessee

         9.       OTHER TERMS AND PROVISIONS

         All other  provisions of the Original  Lease shall remain in effect and
unchanged  except as modified  herein,  and all terms,  covenants and conditions
shall remain in effect as modified by this  Addendum No. 1. If any  provision of
this Addendum No. 1 agreement  conflicts with the Original Lease, the provisions

to Original  Lease  Agreement  to be signed in their names by  themselves  or by
their  duly  authorized  representatives  and  delivered  as their act and deed,
