negatives  thereof or other variations  thereon or comparable  terminology,  and
include statements as to the intent,  belief or current  expectations of Exigent
International,  Inc.,  a Delaware  corporation,  and its  subsidiaries,  and its
directors,  officers  and  management,  with  respect to its future  operations,
performance or position.  These forward-looking  statements are predictions.  No
assurances can be given that the future results  indicated,  whether  express or
implied, will be achieved.  All references to "Exigent" or "we" or "our" or "us"
refer to Exigent International, Inc. or its subsidiaries.

The Company

         Exigent  is a  holding  company,  incorporated  on  March  25,  1996 to
capitalize  on  emerging  high-technology  opportunities.  Exigent was formed by
Software  Technology,  Inc., a Florida corporation  ("STI"), to acquire and hold
all of its issued and outstanding  stock. On January 30, 1997,  Exigent acquired
all of the issued and  outstanding  STI stock in exchange for 3,486,600  Exigent
Common  Shares,  par value  $0.01 per share (the  "Common  Shares")  and 697,320
Exigent  Class A Preferred  Shares,  par value  $0.01 per share (the  "Preferred
Shares") (the "Exchange"). In the Exchange, Exigent also issued 1,070,270 Common
Share  Purchase  Warrants (the  "Warrants")  expiring on January 30, 2000.  Each
Warrant was convertible into one Common Share at $3.00 per Warrant. Prior to the
expiration date, the holders of Warrants  converted 798,560 Warrants into a like
number of Common Shares thereby raising $2,395,680 in additional capital.

         As shown in the following  chart,  Exigent  presently  operates through
three wholly owned subsidiaries. These are STI, a Florida corporation,  FotoTag,
Inc., a Delaware corporation  ("FotoTag"),  and Exigent Solutions Group, Inc., a
Nevada corporation ("ESG"):

                           Exigent International, Inc.
          |-----------------------------|-------------------------------|
          |                             |                               |
Software Technology, Inc.    Exigent Solutions Group, Inc.        FotoTag, Inc.


         Exigent,  through STI, has designed and deployed  satellite command and
control  and  telecommunications  systems for more than  twenty  years.  We have
provided  ground  control  solutions  for dozens of  commercial  and  government
projects,   ranging   from   single   spacecraft   to  the   largest   satellite
constellations.   As  worldwide  demand  for  satellite-based  applications  has
increased,  we have responded by developing a suite of  commercial-off-the-shelf
("COTS")  products  based  on our  experience  in  building  such  systems.  Our
engineers also provide system integration  support for customers  throughout the
United States.

Recent Developments

         In June 1999,  we suspended  system  engineering  work on the Teledesic
satellite program in response to the decreased  activity in the commercial space
industry   during  the  fiscal  year  ended  December  31,  1999.  We  had  been
participating  in a Strategic  Alliance  Agreement  with Motorola since February
1998 under which we supplied system design and command and control  architecture
services for Motorola's  future  satellite  constellations  which included their
activities in support of the Teledesic  program.  The  subsequent  financial and
financing difficulties  experienced by other satellite  constellation  operators
and  developers  resulted  in Exigent  taking a series of actions to  reposition
itself:

o    To enhance our focus on developing and supporting our leading  products and
     technical services in the three distinct  marketplaces in which we operate,
     Exigent  was  reorganized  into three  business  units:  space and  defense
     services (STI); information technology ("IT")(ESG);  and airport operations
     (FotoTag);

o    To strengthen our management  team, we hired Larry  Whitfield  (formally of
     Lockheed,  Tektronix  and Harris  Corporation)  as  President of STI and we
     expanded  STI's sales and marketing team to position us to grow revenues at
     a faster pace;
<PAGE>

o    As a  result  of our  strategy  to place  more  emphasis  on  international
     markets, we recently received our first overseas contracts in Australia and
     Korea;

o    As a result of our  software-defined  radio (SDR)  Domain  Manager Tool Kit
     being  selected  by  a   Raytheon-lead   consortium  as  the  backbone  for
     development of a new  generation of digital radio for the U.S.  military in
     the 21st century, we set up a special business unit to pursue opportunities
     in this technology; and

o    Finally,  in order to  expand  our reach  into the  commercial  sector  and
     develop new vertical market opportunities for our products and services, we
     acquired GEC North America  Corporation  ("GEC"),  a systems  integrator of
     Oracle(R)  -based   solutions.   This  marked  an  important  step  in  the
     implementation of our IT initiative, resulting in the combination of our IT
     business  units  with  GEC  to  form  ESG.  GEC  complements  our  existing
     government   IT   business,    our   enterprise    engineering    and   our
     command-and-control software IT.

Software Technology Inc.

         Since its formation in 1978, STI has provided custom and COTS software,
systems  engineering,  and  software  engineering  services  to a wide  range of
industrial and government entities, including:

o    agencies and  departments  of the U.S.  government  that use satellites for
     research, communication, or in defense programs;

o    commercial  telecommunication  companies,  particularly  those  focused  on
     low-earth-orbit  ("LEO")  satellite systems  providing  wireless  telephone
     services and paging;

o    commercial and government  customers  that require  Management  Information
     Systems ("MIS") and data base development services;

o    commercial launch facilities and contractors that provide commercial launch
     services;

o    aerospace and defense  contractors that develop  computerized  weaponry and
     defense  systems  employing  satellite   technology,   especially  embedded
     software systems;

o    Value Added Resellers  ("VARs") and strategic  partners that develop custom
     or specialized computer applications;  and

o    engineering  firms  that  require software design and development services.

         In addition to providing  general-purpose  and  customized  engineering
solutions,  we have developed the OS/COMET(TM) family of products. This suite of
COTS command and control software  products is our flagship  software  offering.
This  related  group of software  products was  originally  developed to support
satellite ground stations and to integrate and test spacecraft systems. Over the
years, however,  OS/COMET has evolved into a multi-dimensional  general purpose,
integrated tool set. These COTS programs provide a real-time  command,  control,
and data  acquisition  environment  for  government  and  commercial  solutions.
OS/COMET products can be further adapted for use in many complex ground or space
control situations. OS/COMET executes on POSIX-compliant UNIXTM workstations and
makes extensive use of the "X Window System" and the "OSF/Motif"  graphical user
environment  standards.  OS/COMET  currently  includes the  following  family of
products:

         OS/COMET  is  currently  used in two of the world's  largest  satellite
constellations,  Iridium(R) and Global Positioning System ("GPS").  Iridium is a
global wireless  communication system built by a consortium of investors lead by
Motorola.  Iridium offers  customers  local voice calling and paging anywhere on
the planet  through a  constellation  of 66 LEO  satellites  (plus six  on-orbit
spares).  We were also selected by Motorola to become its preferred  supplier of
command  and  control  software  for  its  Celestri  project  and  other  future
communication  systems  projects  (including   Teledesic,   a  constellation  of
broadband  satellites  conceived to be the "Internet in the Sky") because of our
long standing relationship with them.

         Our OS/COMET  products were also selected to upgrade the ground station
software  for the  U.S.  Air  Force's  NAVSTAR  GPS  project.  NAVSTAR  GPS is a
24-satellite GPS constellation which provides worldwide all-weather positioning,
and navigation data.  NAVSTAR GPS's 24 satellites  provide worldwide  navigation
data for  military  and  civilian  aircraft,  spacecraft  and  land  and  marine
applications.

         We also produce OS/COMET Solo,  which is specifically  designed for the
user  who  requires  just  one  satellite,  one test  fixture,  or some  similar
single-use application.  It offers a straightforward migration path to OS/COMET,
ensuring simple and easy future expansion of the system.

         OS/ICC ("Integrated  Control Center") is a versatile,  extensible,  and
scaleable  suite  of  services  and  equipment  that  combines  industry-leading
hardware and software products into an integrated  solution.  OS/ICC may be used

<PAGE>

"out of the box" in its standard form, or may be customized for special customer
use  applications.  OS/ICC is intended to provide seamless software and hardware
reuse and automation across a satellite's entire mission life-cycle,  from early
mission planning and modeling,  through vehicle testing and on-orbit  spacecraft
management. OS/ICC is designed to handle projects ranging from single satellites
to large constellations.

         Calypso and Calypso Pro products are telemetry data  decommutation  and
distribution  tools;  the "Pro" suffix  indicates an  extensible  version of the
basic product.  These products are cost-effective,  easy-to-use and are designed
for  single-node  applications  and test beds that do not  require  the  complex
functionality of the more advanced products such as OS/COMET or OS/COMET Solo.

         The  Pluto   Satellite  Tool  Kit  ("Pluto")   deploys   complex  model
architecture   and  numerous  core  components  for  the  creation  of  "virtual
satellites." The satellite models generated by Pluto can be crafted so that they
are identical to actual spacecraft.  Pluto's object-oriented architecture breaks
a   satellite   into  a  set  of   user-defined   sub-systems   using   standard
object-oriented programming techniques.

Exigent Solutions Group

         In  1999,  we  formed  ESG as an  information  technology  service  and
products  company.  In December  1999, ESG began  offering  Enterprise  Resource
Planning ("ERP") implementation  services following its acquisition of GEC. GEC,
a Charlotte,  NC-based consulting and systems integration firm, is recognized as
an  implementor  of ERP  solutions  using  Oracle  Applications.  ESG  currently
provides the following services:  integrated management  consulting;  design and
development of Internet commerce  solutions;  implementation  and integration of
packaged  software   solutions;   design  and  development  of  custom  software
solutions;  and implementation of ERP systems and production support.  (See Risk
Factors - Risk specific to ESG and Industry Related Risks Specific to ESG).

         ESG also carries the products developed by MiddleWare  Solutions,  Inc.
("Mware").   Mware  develops  inexpensive,   high-performance   message-oriented
products and  distributes  them directly to the end-user over the Internet or on
compact disks ("CD's") through the mail. MWare's first product was ActiveMTM for
Windows.   ActiveM  is  a   publishing   subscribing   tool  that   provides  an
application-transparent  messaging  facility  for ActiveX  environments  such as
Microsoft(R) Visual C++ and Inprise's C++ Builder 3. ActiveM makes sophisticated
cost-effective  networking  available to millions of application  developers who
currently work in the Windows  world.  ActiveM's  target  customer base includes
computer  programmers  who  develop  software  for  the  high-volume  commercial
marketplace (business  applications,  games, etc.), as well as those programmers
producing various scales of in-house  applications.  ActiveM supports  virtually
all network types and topologies,  whether local-area networks (LAN),  wide-area
network  (WAN),  or the  WorldWide  Web.  ActiveM is included in the ESG product
offering.

FotoTag

         FotoTag was formed in 1997 to provide improved  efficiency and security
in the  public  transportation  environment.  FotoTag  develops  and  markets  a
passenger/baggage  reconciliation  system,  "FotoTag(R)",  for use by  airlines,
airports,  and other commercial  transportation systems such as cruise lines and
railroads.  FotoTag  products  and  services may be sold to foreign and domestic
airlines,  as well as foreign and domestic  agencies  that control  airports and
airport   security.   The  FotoTag  system  is  primarily  used  as  an  airport
passenger/baggage reconciliation system.

         In the future,  we expect that FotoTag will provide enhanced  departure
control facilities to improve passenger servicing and reduce airline and airport
management  costs.  The current system utilizes  IATA-standard  barcode,  "smart
card"  technology,   radio-frequency   identification  (RFID)  technology,   and
compressed digital photography. The FotoTag system captures passenger images and
reconciles this visual  information with a traveler's  itinerary,  baggage,  and
travel related documents.

SOFTWARE DEVELOPMENT

         During the last three years, we have invested substantial  resources to
develop and  enhance the  software  products  which we believe are  commercially
marketable.  Generally,  most of our software  development  relates to tracking,
command and control systems,  "horizontal products", which our STI subsidiary is
developing for the ground and space segments of the aerospace/defense  industry.

<PAGE>

Currently  our  "horizontal"  product  suite is applied  only in one  "vertical"
market. We believe that other "vertical" market applications,  such as utilities
and   inventory   intensive   applications,   as  well  as   providers   in  the
telecommunications industry, can utilize these products. (See Risk Factors - Our
Products may not be accepted by the market).

         We  capitalized  $2,144,253,  $3,905,349,  and  $1,149,685  of  product
development in our fiscal years ended  December 31, 1999,  December 31, 1998 and
January 31, 1998,  respectively.  These amounts include investments allocated to
each of: the OS/COMET family of products, ActiveM, and FotoTag.

         We expensed $271,576,  $180,671,  and $47,854, on internally  sponsored
research  and  development  during our fiscal  years ended  December  31,  1999,
December 31, 1998, and January 31, 1998,  respectively.  These expenditures were
made so that we could  evaluate  new products and services as well as update and
expand our current technologies.

         In  addition  to the funds we  invested  in  software  development,  we
invested  more than  $1,500,000  during the past two years to  develop  advanced
systems  engineering  for future  constellations  in accordance with a Strategic
Alliance Agreement with Motorola. (See Risk Factors - Length of Sales Cycle).

MARKETING AND SALES

         We rely upon our  senior  corporate  management,  sales  and  marketing
personnel,  project  managers  and  senior  technical  staff  to  carry  out our
marketing program.  Our marketing program includes the development and execution
of marketing  plans,  proposal  presentations  and the  performance of marketing
related tasks.  These  individuals are  responsible  for collecting  information
concerning  requirements  of current and  potential  customers  in the course of
contract   performance  and  formal  and  informal  briefings,   from  published
literature and through participation in professional and industry organizations.
Our senior  management  then evaluates this  information,  identifies  potential
business  opportunities and coordinates  proposal efforts. The primary source of
business  in our  existing  markets is  referred  to us by  existing  customers.
Additionally,  we advertise  extensively in various  industry  publications  and
participate in numerous trade shows.

         We  distribute  our  products  and  services  and license our  products
indirectly,  through  VARs,  and  directly  to  end-users.  (See Risk  Factors -
Proprietary Rights).

REVENUE SOURCES

         Our revenues are currently dependent on four significant customers, the
Naval  Research  Laboratory  (the  "NRL"),   Allied  Signal  Technical  Services
("Allied"),   Lockheed  Martin   Corporation   ("Lockheed")  and  a  proprietary
government organization.  Three of which, individually,  accounted for more than
10%,  and in the  aggregate,  accounted  for more  than 73% of our  consolidated
revenues for the fiscal year ended  December 31, 1999.  The loss of any of these
customers  would have a materially  adverse  affect on our business,  results of
operations  and financial  condition.  (See Risk Factors -  Significant  Revenue
Derived from Government Contracts).

         During  1998,  we  entered  into a contract  with a fourth  proprietary
government  customer,  for a period which may extend  through  October 2003. The
initial estimated value of this contract was $7,500,000. We are currently in the
second full year of the contract and our relationship with this client continues
to be  good.  Under  the  contract  we  primarily  provide  applications  system
engineering  related to the client's  MIS.  (See Risk Factors -  Performance  of
Government Contracts may require Security Clearance).

         STI has several  contracts with the NRL. Our largest  contract with the
NRL relates to space systems applications and operations, and was renewed in May
1998 for five years. In addition to space  applications and operation  services,
STI  provides  the NRL  with IT  development  and  maintenance  services.  STI's
principal IT assignment has been replacing NRL's Job Cost Accounting system. STI
has developed a  state-of-the-art  Oracle-based  information system running on a
cluster of UNIX database  servers,  employing  multiple NT and LINUX Web servers
with user  interfaces  implemented  on Web-centric  technologies.  Our principal
contract with the NRL provides for us to perform  services  during the next five
years, with a total estimated cost of $57,167,518 and a fixed fee of $4,370,901.
As of December 31, 1999, STI received cost payments and fees in the aggregate of
$27,049,161   under  the   contract.   Fees  on  this  contract  are  billed  at
approximately 7.5% of costs.

         STI also receives  revenues from Allied under various  purchase orders.
For the fiscal  year ended  December  31,  1999,  Allied  paid us  approximately
$3,952,065,  while  approximately  $1,686,553  remains in backlog under existing
purchase  orders.  The contract with Lockheed  relates to a GPS project with the
U.S. Air Force for which Lockheed serves as one of the subcontractors and Boeing
serves  as  the  prime  contractor.  The  contract  commenced  August  1995  and
terminates  September  30,  2000,  unless  modified by  Lockheed.  STI  received
$2,848,465  under this contract for the fiscal year ended December 31, 1999 with
a funded  backlog at that time of  approximately  $404,986.  (See Risk Factors -
Risks Specific to STI).
<PAGE>

         ESG  currently  has two revenue  sources,  an IT "task  order" that was
appended to the STI contract with the NRL and GEC's IT business. The performance
of IT services for the NRL resulted in  approximately  $5,000,000 in revenue for
the fiscal year ended  December 31, 1999.  The GEC portion,  for the fiscal year
ended  December 31, 1999,  was nominal due to the  mid-December  closing of that
acquisition.  GEC  revenues  for the entire  year ended  December  31, 1999 were
approximately $5,400,000.

         See  "Item  7.  Management's   Discussion  and  Analysis  of  Financial
Condition and Results of Operations" and Note 12 to the Financial Statements for
additional information on our dependence on certain customers.

CONTRACTS

         A  substantial  portion of our revenues are derived from  contracts and
subcontracts  with the United States Department of Defense (the "DOD") and other
federal  government  agencies.  Many of our contracts are  competitively bid and
awarded on the basis of technical merit,  personnel  qualifications,  experience
and price. Recently, the Federal Acquisition Streamlining Act of 1994 encouraged
the use of "commercial"  type pricing on dual use products.  Our future revenues
and income could be materially  affected by changes in procurement  policies,  a
reduction in government  expenditures  for our products and services,  and other
risks generally associated with federal government contracts. (See the following
Risk  Factors -  "Contracts  Subject to  Termination"  and  "Funding  Subject to
Government Regulation").

         Our contracts with the federal government range from one to five years.
Such contracts may be conditioned  upon continued  availability of congressional
appropriations. Any variance between anticipated budget and actual congressional
appropriations  may  result  in  a  delay,  reduction  or  termination  of  such
contracts.  Until  differences  between budget requests and  appropriations  are
resolved,  contractors often experience  revenue  uncertainties  with respect to
available  contract funding during the first quarter of the government's  fiscal
year beginning October 1.

         Our   federal    government    contracts   may   be   structured    as:
cost-reimbursement  contracts,  time and  materials  contracts  and fixed  price
contracts.  Cost-reimbursement  contracts provide for reimbursement of costs (to
the  extent  allowable,  allocable  and  reasonable  under  Federal  Acquisition
Regulations)  and the  payment  of a fee.  The fee may  either  be  fixed by the
contract  (cost plus fixed fee) or variable,  based upon cost control,  quality,
delivery and the customer's  subjective  evaluation of the work (cost-plus-award
fee).  Under time and  materials  contracts,  we receive a fixed amount by labor
category for services  performed and are reimbursed  (generally without fee) for
the cost of  materials  purchased to perform the  contract.  Under a fixed price
contract,  we agree to perform certain work for a fixed price and,  accordingly,
realize  the  benefit  or  detriment  to the  extent  that  the  actual  cost of
performing  the work differs from the contract  price.  Revenues  generated from
contracts with the federal  government or its prime  contractors  for the fiscal
year ended December 31, 1999, were approximately  73.7% from  cost-reimbursement
contracts,   approximately   20.2%  from  time  and   materials   contracts  and
approximately  6.1% from fixed  price  contracts  of total  revenues.  (See Risk
Factors - Contracts Subject to U.S. Government Regulation).

         Our allowable federal government contract costs and fees are subject to
audit  by  the   Defense   Contract   Audit   Agency.   Audits   may  result  in
non-reimbursement of some contract costs and fees. While the government reserves
the right to conduct further  audits,  we have not experienced any material cost
recovery disallowances for audits conducted through fiscal 1997.

         Our federal  government  contracts  may be  terminated,  in whole or in
part, at the  convenience of the  government.  If a termination  for convenience
occurs,  the  government  is  generally  obligated  to pay our  costs  under the
contract plus a pro rata fee based upon the work completed.  When we participate
as a subcontractor,  we risk termination of the contract if the prime contractor
does  not  perform  its  contract  duties.  Similarly,  when  we act as a  prime
contractor,  or employ subcontractors,  we risk termination of the contract if a
subcontractor  does not perform its subcontracting  duties.  (See Risk Factors -
Contracts Subject to Termination without Cause).

         Some of our contracts with the federal  government contain options that
are  exercisable  at  its  discretion.  An  option  may  extend  the  period  of
performance  for one or more  years for  additional  consideration  on terms and
conditions  similar to those contained in the original  contract.  An option may
also increase our duties and assign us new tasks. In our experience, options are
commonly exercised by the government.

         Our federal  government  contracts  require  that we maintain  adequate
security measures.  We have implemented  security procedures that we believe are
adequate to satisfy the requirements of our federal government contracts.


<PAGE>

         All of our  commercial  contracts are either time and material or fixed
price  agreements.  These  agreements  generally  call  for a  specified  set of
requirements  to be delivered at a negotiated  price.  Under time and  materials
contracts,  we receive a fixed amount by labor  category for services  performed
and we are  reimbursed  (generally  without  fee)  for  the  cost  of  materials
purchased to perform the  contract.  Under a fixed price  contract,  we agree to
perform certain work for a fixed price and, accordingly,  realize the benefit or
detriment to the extent that the actual cost of performing the work differs from
the  contract  price.  These  contract  types  are  typically  broken  down into
milestones with payments made at each milestone.  These milestones are generally
referred  to as earned  value  milestones  and are  commonly  used to  benchmark
progress, help a customer track status, and provide trigger points for payments.
(See Risk Factors - Industry Related Risks of STI).

         Over the past  five  years,  STI has  entered  several  contracts  with
Motorola.  Some of the contracts  were fixed price  contracts and some were time
and material  contracts.  Most of the revenues  generated by Motorola  contracts
during the past five years were received under an agreement executed in February
1994,  pursuant to which,  STI agreed to provide  Motorola  with  satellite  and
ground  control   software  for  the  system  control  segment  of  the  Iridium
Communications  System.  As of December  31, 1999,  STI  received  approximately
$45,447,645  from Motorola under this and other  contracts.  The  development on
Iridium was  completed  during the eleven  months ended  December 31, 1998.  STI
continued to be covered  under a  maintenance  agreement  and through a time and
material  contract for the year ended  December 31, 1999 with  Motorola.  We are
unable to accurately  predict the  continuance  of coverage  under a maintenance
agreement  with Motorola  because of the  uncertain  situation  surrounding  the
Iridium reorganization.  In addition to STI's business with Motorola, we entered
into a strategic  alliance  agreement with Motorola in the pursuit of developing
space program technology,  particularly the Teledesic project.  Over a period of
eighteen  months  we  invested  more than  $1,500,000  in  connection  with this
agreement.   After  thoroughly  reviewing  the  circumstances   related  to  our
investment as well as discussing  the matter with  Motorola,  we determined  the
investment was impaired.  As a result,  we chose to write down $1,000,000 in the
fourth  quarter of the fiscal year ended  December 31, 1999, to account for such
impairment.

         FotoTag  generated  limited  revenues in the fiscal year ended December
31, 1999,  based on the development  plans and schedule to incorporate  customer
features  and  functionality.  The  revenues  generated  were through a contract
testing the FotoTag product with the Federal Aviation Administration (the "FAA")
and an  international  airline.  We  completed  testing  with  the  FAA  and are
currently  discussing an ongoing relationship with them. Because we view this as
a limited  opportunity  we have  adjusted  the carrying  value by  approximately
$380,000 during the fourth quarter ended December 31, 1999.

Backlog

         As of December 31, 1999,  and December 31, 1998,  we estimate  that our
firm   backlog   orders  were   $19,011,492   and   $14,040,033,   respectively.
Approximately  $13,188,846  of our backlog in the fiscal year ended December 31,
1999 relates to the unfunded portion of awarded government  contracts.  Over the
next two to three years we expect that $27,370,117 in unawarded task orders will
be funded and awarded in connection  with our direct contract with the NRL. (See
Risk Factors - Estimated Backlog under Government Contracts).

Regulatory Environment

         Pluto and OS/COMET are subject to export control  regulations  pursuant
to the  International  Trafficking and Arms Regulation  administered by the U.S.
Department of State.  Regulatory  changes could materially  adversely affect our
operations  by  restricting  sales and  marketing  efforts.  Changes  in, or our
failure to distribute products in compliance with, applicable export regulations
could have a material  adverse effect on our business,  financial  condition and
results of operations. The delays inherent in this governmental approval process
have  in the  past  caused,  and  may  in the  future  cause  the  cancellation,
postponement or  rescheduling of the  installation of ground station systems for
our  customers.  This  may have a  material  adverse  effect  on the sale of our
products to such customers. (See Risk Factors - Planned International Operations
May Not Succeed).

         We believe that our business operations are in material compliance with
applicable governmental regulations. We are not aware of any pending legislation
that if enacted could have a material adverse effect on our business,  financial
condition and results of operations.

Employees

         As of December 31, 1999,  we had 307  employees.  None of our employees
are represented by a union and we consider our relationship with employees to be
good.

RISK FACTORS

A significant  portion of our revenue is derived from contracts or  subcontracts
funded by the U.S. government.

         The following table lists the approximate  revenues, as a percentage of

</TABLE>

         We expect  that U.S.  government  contracts  are likely to  continue to
account  for  a  significant  portion  of  our  revenues  in  the  near  future.
Accordingly,  our financial  performance  may be adversely  affected by changing
U.S.  government  procurement  practices  and  policies  as well as  declines in
defense agency  spending.  The factors that could have a material adverse effect
on our ability to win new contracts with the U.S. government, or retain existing
contracts, include the following:  budgetary constraints;  changes in government
funding levels, programs, policies or requirements;  technological developments;
the adoption of new laws or regulations; and general economic conditions.

         In  addition,   some  of  our  contracts   individually   contribute  a
significant  percentage of our revenues.  Two of our largest contracts generated
approximately  66.5% of our  revenues  for fiscal year  1998(B) and 62.6% of our
revenues for the fiscal year 1999.  This  includes one contract  that  generated
approximately  47.3% of our  revenues  for fiscal year  1998(B) and 49.1% of our
revenues  for  fiscal  year  1999.  A  relatively  small  number  of large  U.S.
government  contracts  are  likely to  continue  to  account  for a  significant
percentage of our revenues in the future.  Termination of any of these contracts
or our inability to renew or replace  these  contracts  when they expire,  could
have a material adverse effect on our business,  financial condition, or results
of operations.

Our  contracts  and  subcontracts  that are  funded by the U.S.  government  are
subject to termination without cause by the government.

         All of our  contracts  and  subcontracts  that are  funded  by the U.S.
government are subject to termination  for  "convenience,"  meaning  termination
without  cause.  Should a contract  be  terminated  without  cause,  we would be
reimbursed  for allowable  costs incurred  through the date of  termination  and
would  be  paid  a  proportionate  amount  of the  stipulated  profits  or  fees
attributable  to  work  actually  performed.  Termination  of any  of our  large
government  contracts  could have a  material  adverse  effect on our  business,
financial condition, or results of operations.
<PAGE>

Our  contracts  and  subcontracts  that are  funded by the U.S.  government  are
subject to government regulations.

         Government   contracts   require   compliance  with  various   contract
provisions  and  procurement  regulations.  The  adoption  of  new  or  modified
procurement  regulations  could have a material  adverse effect on our business,
financial  condition,  and  results  of  operations  or  increase  the  costs of
competing  for or  performing  government  contracts.  Any  violation  of  these
regulations  could result in the  termination  of the  contracts,  imposition of
fines and/or  exclusion  from  government  contracting  and  government-approved
subcontracting  for some specific  time period.  Most  government  contracts are
subject to modification  or termination in the event of changes in funding,  and
our contract  costs and revenues are subject to adjustment as a result of audits
by the Defense Contract Audit Agency and other government  auditors.  We reflect
any adjustments required by such audits in our financial statements. Although we
have not yet been required to make any material audit  adjustments,  there is no
assurance that such adjustments will not be required in the future. The award of
government contracts also is subject to protest by competitors, which can result
in the  re-opening of the bidding  process,  unanticipated  legal costs,  or the
award of a contract to a competitor.

Our  contracts  and  subcontracts  that are  funded by the U.S.  government  are
subject to a competitive bidding process.

         Government  contracts  generally  are  awarded  to us  through a formal
competitive  process  in which we may have many  competitors.  Upon  expiration,
government contracts may be subject,  once again, to the competitive process. We
cannot  assure  you that we will be  successful  in winning  contract  awards or
renewals in the future.  Our failure to renew or replace  these  contracts  when
they expire  could have a material  adverse  effect on our  business,  financial
condition, or results of operations.

         Our contracts and  subcontracts  with federal  government  agencies are
subject  to  competition  and are  awarded  on the  basis  of  technical  merit,
personnel  qualifications,   experience,  and  price.  Our  business,  financial
condition and results of operations  could be materially  affected by changes in
procurement  policies,  a reduction in funds  available for the services that we
provide, and other risks generally associated with federal government contracts.
New government contract awards are also subject to protest by competitors at the
time  of  award.  This  can  result  in the  re-opening  of the  competition  or
evaluation  process or the award of a contract to a competitor.  We consider bid
protests  to be a  customary  element  in the  process of  procuring  government
contracts.

Our  contracts  and  subcontracts  that are  funded by the U.S.  government  are
subject to the budget and funding process of the U.S. government.

         Many of the U.S.  government  programs  in which  we  participate  as a
contractor or subcontractor  extend for several years, but are funded only on an
annual  basis.  Accordingly,  our  contracts  and  subcontracts  are  subject to
termination,  reduction,  or  modification  in  the  event  of  changes  in  the
government's  requirements  or  budgetary  constraints.  Additionally,  when  we
participate in a project as a  subcontractor,  we are subject to the risk that a
prime contractor may fail or be unable to perform the prime contract.

         In  addition  to the  right  to  terminate,  government  contracts  are
conditioned upon the continuing availability of Congressional funding.  Congress
usually allocates funds on a fiscal-year basis even though contract  performance
may take several  years.  Consequently,  at the outset of a major  program,  the
contract is usually  incrementally  funded,  and  additional  funds are normally
committed to the contract by the procuring agency as funds are made available by
Congress for future  fiscal years.  In addition,  contractors  often  experience
revenue  uncertainties during the first quarter of the U.S.  government's fiscal
year,  which begins October 1, until  differences  between  budget  requests and
appropriations  are  resolved.  To date,  Congress  has  funded all years of the
multi-year major program  contracts for which we have served as prime contractor
or  subcontractor,  although there is no assurance that this will be the case in
the future.

The  estimated  backlog  under  our  government  contracts  is  not  necessarily
indicative of revenues that will actually be realized under the contracts.

         Many of our government contracts are multi-year contracts and contracts
with option years,  and portions of these contracts are carried forward from one
year to the next as part of our contract backlog.  Backlog means the total value
of all contracts less the revenues earned on those same contracts. The estimated
backlog under a government  contract is not  necessarily  indicative of revenues
that  will  actually  be  realized  under  that  contract.   Congress   normally
appropriates  funds for a given  program on a  fiscal-year  basis,  even  though
actual  contract  performance  may  take  many  years.  As a  result,  contracts

<PAGE>

ordinarily are only partially funded at the time of award, and additional monies
are normally  committed to the  contract by the  contracting  agency as Congress
makes  appropriations in subsequent fiscal years. There can be no assurance that
Congress will appropriate funds or that procuring  agencies will commit funds to
our government  contracts for their anticipated terms. In addition,  most of our
government  contracts  have an initial  term of one year plus a number of option
years. We cannot assure that the government  will extend a contract  through its
option years.  Certain of our large  contracts  provide that we will not receive
payment until the services  under those  contracts are requested and  performed.
There is no assurance  that  cancellations  or adjustments in the terms of these
contracts might not occur.  In addition,  our services under these contracts may
not be requested at the anticipated levels in the future.

Performance of some of our government contracts may require security clearance.

         Some of our contracts with government agencies require that some of our
employees and procedures meet security clearance requirements. If problems, such
as delays or denials,  develop in  connection  with meeting  security  clearance
requirements, the government could materially limit our ability to perform these
contracts.

Our  commercial  contracts  are subject to  competition  and strict  performance
requirements.

         Although a significant  portion of our revenues are generated  from the
sale of our services and products in commercial  markets,  there is no assurance
that we will  continue to compete  successfully  in these  markets.  Many of our
commercial  contracts  are  for a  fixed  price.  We are  therefore  subject  to
substantial  risks  relating to  unexpected  cost  increases  and other  factors
outside of our control. We may fail to anticipate  technical problems,  estimate
costs accurately, or control costs during performance of a fixed price contract.
Any of these failures may reduce our profit or cause a loss under our commercial
contracts.  In addition, our revenues on fixed price contracts are recognized on
a percentage-of-completion basis. This means that the company calculates a ratio
of costs  incurred to costs expected to be incurred for each fixed price job and
then  multiplies  that same ratio by the fixed price contract value to determine
total  revenue for each fixed price job.  As a result,  contract  price and cost
estimates  on  fixed  price  contracts  are  reviewed  periodically  as the work
progresses,  and  adjustments  are  reflected  in income in the period  when the
estimates are revised.  To the extent that these  adjustments  result in a loss,
reduction,  or elimination of previously  reported profits, we would recognize a
charge  against  current  earnings,  which could be material and have a material
adverse effect on our business, financial condition, or results of operations.

         In connection with certain commercial contracts,  we may be required to
obtain bonds,  letters of credit, and similar guarantees.  There is no assurance
that we will be  successful  in obtaining  these types of guarantees or that the
guarantees available will be affordable in the future.

         We  typically  must agree to meet strict  performance  obligations  and
project  milestones,  which we may not be able to  satisfy.  Our failure to meet
these  performance  obligations  and  milestones  may permit the other  party to
terminate the contract  and,  under certain  circumstances,  recover  liquidated
damages or other penalties from us.

Intense  competition  in the  satellite  ground system  industry  could harm our
financial performance.

         We experience significant competition.  We believe that we are one of a
few companies in the United  States,  which derive the majority of their revenue
from  the  development  of  satellite  ground  systems.  In  addition  to  these
companies,   approximately  twelve  large  aerospace/defense   contractors  have
developed  satellite  control systems either in-house as primary  contractors or
through subcontractors. As a result, some of our competitors are also current or
potential customers. Our competitors, which in many cases are customers as well,
include the following:

o        Lockheed Martin Corporation;
o        Integral Systems;
o        Hughes Space Company;
o        Loral Space & Communications Ltd.;
o        Orbital Sciences Corporation;
o        AlliedSignal;
o        Computer Sciences Corporation;
o        Alcatel Espace;
o        Matra Marconi Space; and
o        Aerospatiale.
<PAGE>

          Many of our  competitors  are  significantly  larger and have  greater
financial resources.  Some of these competitors are divisions or subsidiaries of
large,  diversified  companies  that have access to the  financial  resources of
their parent  companies.  We may not be able to compete  effectively  with these
companies  or maintain  them as  customers  while  competing  with them on other
projects. In addition,  several smaller companies have specialized  capabilities
in similar areas. Our products also face competition from certain  off-the-shelf
products  developed by the  government  for  satellite  command and control.  We
cannot  accurately  predict  how our  competitive  position  may be  affected by
changing  economic  or  competitive   conditions,   customer  requirements,   or
technological  developments.  We principally  obtain  contracts and subcontracts
through  competitive  procurements  offered by the U.S. government or commercial
enterprises. We cannot assure you that we will be able to compete successfully.

Our major products may not be accepted by the market.

         Our earnings  growth  depends upon market  acceptance of our commercial
off-the-shelf  satellite  telemetry,  command  and  control  software  products,
including our base  product,  OS/COMET and related  products.  Because the space
industry has historically used customized software  solutions,  we cannot assure
you that our potential customers will be interested in licensing these products.
Whether  potential  customers  will  license  our  software  depends  on several
factors, including:

     o    how well our products perform;

     o    how well our products can be integrated  into our customers'  existing
          technologies; and

     o    whether  our  customers  can  achieve  cost  savings  and become  more
          efficient by using our software.

The failure of potential customers to license our products would have a material
adverse effect on our business, financial condition and results of operations.

The length of our sales  cycle  increases  our costs and  hinders our ability to
procure contracts.

          We believe that the period of time between  initial  customer  contact
and the sale of software to the customer is  typically  between 12 to 18 months,
and may  sometimes  take as long as 24  months.  The  reason  for this is that a
potential  customer will conduct  extensive  and lengthy  tests before  deciding
whether to  purchase or license our  product.  While the  customer is making its
decision,  our sales and  marketing  expenses may be  significant.  In addition,
during this time period, there is a risk that space missions or projects will be
cut  back or  terminated,  that  customer  budgets  will be  reduced,  or that a
customer will decide that it no longer wants to purchase or license our product.
If  this  occurs  unexpectedly,   particularly  if  the  potential  contract  is
significant,  our business,  financial condition and results of operations could
be adversely effected.

We may not be able to protect our  proprietary  rights.  We may  infringe on the
proprietary rights of other persons.

         Our success and ability to compete are dependent,  in large part,  upon
our  proprietary  rights.  To  protect  those  rights,  we rely  primarily  on a
combination  of copyrights,  trade secret laws,  trademarks,  patents,  employee
confidentiality,    non-competition   and   invention   assignment   agreements,
third-party  non-disclosure  agreements and other methods. The steps taken by us
may not be  adequate  and third  parties  may  infringe  or  misappropriate  our
copyrights,  patents  and  other  proprietary  rights.  In  addition,  effective
trademark, patent, copyright and trade secret protection may not be available in
every country in which our products  will be sold or licensed.  We may be forced
to bring lawsuits to enforce our rights, which could result in substantial costs
and take time and attention away from our business.

         We  also  may  be  accused  of  infringing  or   misappropriating   the
intellectual  property  rights of other  persons.  In our  licenses and software
development and distribution  agreements with our resellers,  we generally agree
to indemnify  those third  parties for any expenses  and  liabilities  that they
incur  from  claims  of  infringement  or  misappropriation.  The  amount of our
indemnity  obligation  may be greater  than the  revenues  we receive  under the
contract.  If we are sued for possible  infringement or  misappropriation of the
rights of other  persons,  even if the claims are not valid,  the lawsuit  could
result in  substantial  costs,  take time and attention  away from our business,
cause us to delay  shipments  of  products  or require  us to enter into  costly
royalty  or  licensing  agreements.  If a  royalty  or  licensing  agreement  is
required,  and we cannot  enter into a  satisfactory  agreement,  our  business,
financial condition and results of operations could be adversely affected.
<PAGE>

         We also license certain  technologies and software  products from third
party   developers.   The  agreements   with  these   developers  are  generally
non-exclusive  and may be  terminated  at any time by either  party upon written
notice.  If the developers  terminate these  agreements,  develop other products
that compete with our products or provide  their  products and  expertise to our
competitors, our business, financial condition or results of operations could be
adversely affected. Further, we may be accused of infringing or misappropriating
the  intellectual  property  rights of other  persons  by using  these  licensed
products.  If we are sued for possible  infringement or  misappropriation of the
rights of other  persons,  even if the claims are  invalid,  the  lawsuit  could
result in  substantial  costs,  take time and attention  away from our business,
cause us to delay shipments of products or require us to enter into a new costly
royalty or  licensing  agreements.  If a new royalty or  licensing  agreement is
required,  and we cannot  enter into a  satisfactory  agreement,  our  business,
financial condition and results of operations could be adversely affected.

         Any one of these  consequences  could have a material adverse effect on
our business, financial condition or results of operations.

         Under some government contracts,  we have developed software that i) we
are  commercializing,  or ii) in the future we may decide to  commercialize.  In
order to  commercialize  that  software,  we  might  need to  invest  additional
research  and  development  funds to  re-market  the  software  as a  commercial
product. If the product was developed using any government  funding,  government
regulations  and contract  provisions  may prevent us from selling the resulting
product to any  government  agencies.  If the  primary  market  for a  potential
product is government  agencies,  we may not be able to recover  invested  funds
through sale of the product.  In addition,  the government  may acquire  certain
rights to those software programs developed by us under government  contracts or
subcontracts.  Information relating to the programs or products may be disclosed
to third parties, including our competitors.

We depend upon attracting and retaining a highly skilled professional staff.

         Our success depends in part upon our ability to attract, retain, train,
and motivate highly skilled  employees,  particularly in the area of information
technology.  We face significant competition for employees with the computer and
technology  skills required to perform our services and create our products.  In
addition,  we must often comply with provisions in government  contracts,  which
require our employees to have specified  levels of education,  work  experience,
and security  clearances.  We cannot  guarantee  that we will be  successful  in
attracting a sufficient number of highly skilled and qualified  employees in the
future. The loss of our key technical personnel,  or our inability in the future
to attract key  employees or to relocate  them as required by  customers,  could
have a material adverse effect on our business,  financial condition, or results
of operations.

We  may  not  be  able  to  accurately  predict  the  success  of  our  wireless
communications systems.

         A  number  of  our   commercial   product   markets  in  the   wireless
communications  area,  including our SDR products,  have only recently  begun to
develop.  Because these markets are  relatively  new, it is difficult to predict
the rate at which  these  markets  will grow,  if at all.  If the market for our
products in the  commercial  wireless  communications  area fails to grow, or it
grows more  slowly than  anticipated,  our  business,  financial  condition  and
results of operations could be materially adversely affected. Conversely, to the
extent  that growth in these  markets  results in  capacity  limitations  in the
wireless  communications area, our business,  financial condition and results of
operations could also be materially adversely affected.

Industry Related Risks Specific to STI

Our success is dependent on the continued growth of the space industry.

         Since our customers are primarily  concentrated  in the space industry,
our success will depend on the continued  growth in the space industry  software
market.  The space  industry has grown rapidly in the past few years as a result
of technological advancements.  These advancements have lead to lower launch and
satellite production costs and the decreased safety risks related to satellites.
Further,   the  increased   demand  for  advanced   wireless  and  "broad  band"
communication  services has caused  growth in the space  industry.  If the space
industry  ceases to grow,  the demand for our products will  decrease.  This may
have a material adverse effect on our business,  financial condition and results
of  operations.  Further,  we cannot  accurately  predict  the space  industry's
potential  size or future growth rate. We are also unable to accurately  predict
the future needs for satellite command software and related services.


<PAGE>


We may be exposed to product  liability  or related  claims with  respect to our
products.

         Our products are mission-critical  parts of sophisticated and extremely
expensive  satellite  systems.  Should a satellite  mission  fail, or should the
system's  service  become  unavailable,  due to a failure or  malfunction in the
ground system,  we could be sued for product  liability or related  claims.  Any
products  liability or related claim could have a material adverse effect on our
business, financial condition, or results of operations. We have found obtaining
insurance to cover products liability claims to be impractical.

Our  products  may  become  obsolete  due to rapid  technological  change in the
satellite industry.

         Any of our products could become  obsolete at any time due to the rapid
technological  changes in the satellite  industry.  We may not be able to update
our  products  quickly  enough  to  remain   competitive.   The  rapid  pace  of
technological  change  in our  industry  exposes  us to risk of loss  due to the
development of superior  technologies by our competitors.  We are also dependent
upon technologies  developed by third parties for integrating our ground systems
with a variety of satellite systems. As land-based  telecommunications  services
expand, demand for certain types of satellite-based services may be reduced. New
technology used by our competitors  could render  satellite-based  services less
competitive by satisfying  consumer  demand in alternative  ways,  such as fiber
optic and wire-based versus wireless,  or through the use of  telecommunications
standards that are incompatible with existing  satellite  systems.  In addition,
our  success  depends  upon our ability to  introduce  innovative  products  and
services to the market on a cost-effective and timely basis.

Our planned international operations may be expensive and may not succeed.

         We have limited  experience in marketing,  selling and  supporting  our
services in foreign countries.  Development of such skills may be more difficult
or take longer than we anticipate, especially due to language barriers, currency
exchange  risks  and the  fact  that  the  Internet  infrastructure  in  foreign
countries may be less advanced than the United States' Internet  infrastructure.
To date,  we have not  generated  significant  revenues  from  engagements  with
international clients. We recently opened offices in London and Singapore and we
intend to expand our  operations  internationally  in future  periods by opening
other  international  offices and hiring  international  management,  strategic,
technical, design, sales, marketing and support personnel.

         We may be unable to successfully  market, sell, deliver and support our
services  internationally.   If  we  are  unable  to  expand  our  international
operations  successfully  and  in  a  timely  manner,  our  business,  financial
condition  and  operating  results  could be seriously  harmed.  We will need to
devote  significant  management  and  financial  resources to our  international
expansion.  In  particular,  we will  have to  attract  and  retain  experienced
management,   strategic,   technical,  design,  sales,  marketing,  and  support
personnel  for our  international  offices.  Competition  for such  personnel is
intense, and we may be unable to attract and retain qualified staff.

         Moreover,   international  operations  are  subject  to  a  variety  of
additional risks that could seriously harm our financial condition and operating
results. These risks include the following:

o   problems in collecting accounts receivable;
o   the impact of recessions in economies outside the United States;
o   longer payment cycles;
o   fluctuations in currency exchange rates;
o   political instability;
o   unfamiliar governmental structures and laws;
o   restrictions  on  the import and export of certain  sensitive  technologies,
    including ground control  systems for satellite  communications (see below);
    and
o   seasonal reductions in business activity in certain parts of the world, such
    as during the summer months in Europe.

         Various  agencies and departments of the U.S.  government  regulate our
ability to pursue business  opportunities outside the United States.  Exports of
space-related  products,  services,  and technical  information require licenses
granted by the U.S. government.  We do not currently have blanket  authorization
to export our products and services  internationally.  We cannot assure you that
we will be able  to  obtain  blanket  export  authorization  in the  future.  In
addition, we cannot assure you that we will be able to obtain necessary licenses
or approvals on a per-  transaction  basis,  and our  inability to do so, or our
failure to comply with the terms of the authorization when granted, could have a
material  adverse  effect on our business,  financial  condition,  or results of
operations.

Risks Specific to ESG

We may not be able to adjust our fixed operating costs if our revenues decline.

         A high percentage of our operating expenses, particularly personnel and
rent, are fixed in advance of any particular quarter. As a result, unanticipated
variations  in the number or  progress  of our  projects  may cause  significant
variations in operating  results in any  particular  quarter and could result in
quarterly losses.

         An unanticipated  termination of a major project,  a client's  decision
not to proceed with a project we anticipated, or the completion during a quarter
of several  major client  projects  could  require us to maintain  underutilized
employees which could have a material adverse effect on our business,  financial
condition  and  results  of  operations.  Our  revenues  and  earnings  may also
fluctuate from quarter to quarter based on such factors as:

o   the contractual terms and timing of completion of projects;
o   delays incurred in connection with projects;
o   the adequacy of provisions for losses;
o   the  accuracy  of  our  estimates  of resources required to complete ongoing
    projects; and
o   general economic conditions.

Our  reputation  and business may be damaged if we are unable to satisfy  client
expectations  as a result of the increased  size and  complexity of the software
solutions that we implement.

         The average dollar size of our solutions has grown significantly, while
the timeframe for delivering  solutions has generally  decreased.  As our client
engagements become larger, more complex, and more time sensitive the development
process  becomes  more  difficult to manage.  As a result,  the  likelihood  and
consequences  of mistakes  increase.  Any  inability  by us to  complete  client
solutions in a timely manner,  any defects contained in the solutions we deliver
and any  other  failure  by us to  achieve  client  expectations,  would  have a
material adverse effect on our reputation with the affected client and generally
within our industry.  This could have a material adverse effect on our business,
and our results of operations and our financial condition may suffer.

Our  operating  results  may suffer as a result of our  dependence  on a limited
number of client projects.

         We  currently  derive and expect to  continue in the future to derive a
significant  portion of our annual and quarterly  revenues from a limited number
of clients for whom we perform  large  projects.  Consequently,  the loss of any
principal client could have a material adverse effect on our business, financial
condition and results of operations.

Competition from bigger, more established competitors who have greater financial
resources could result in price  reductions,  reduced  profitability and loss of
market share.

         Competition in the eBusiness services market is intense.  If we fail to
compete  successfully  against our current or future competitors,  our business,
financial  condition and operating  results may be seriously  harmed. We compete
against companies selling electronic commerce software and services,  as well as
against corporate in-house  development  efforts seeking to engage in electronic
commerce.  We expect competition to persist and intensify in the future. We also
cannot be certain that we will be able to compete  successfully with existing or
new competitors.

         Because  relatively low barriers  exist for companies  seeking to enter
our market,  we expect many new companies to enter without much  difficulty.  We
expect that  competition  will continue to intensify and increase in the future.
Some large IT consulting firms have recently announced that they intend to focus
more resources on eBusiness engagements. We are unable to guarantee that we will
be retained by our existing or our future clients for later stages of work.

         The vast  majority of our  current  competitors  have longer  operating
histories,  a larger  client base,  larger  professional  staffs,  greater brand
recognition and greater financial, technical, marketing and other resources than
we do. This may place us at a  disadvantage  in responding  to our  competitors'
pricing strategies,  technological  advances,  advertising campaigns,  strategic
partnerships and other  initiatives.  In addition,  many of our competitors have
well-established  relationships  with our current and potential clients and have
extensive knowledge of our industry. As a result, our competitors may be able to

<PAGE>

respond  more  quickly  to new or  emerging  technologies  as well as changes in
customer requirements. Our competitors may also be able to devote more resources
to the  development,  promotion and sale of their  services  than we can.  Those
competitors who offer more  standardized or less customized  services than we do
may have a substantial cost advantage,  which could force us to lower our prices
thereby adversely affecting our operating margins.

         Some of our current and potential  competitors also have established or
may in the future establish  cooperative  relationships among themselves or with
third parties to increase their ability to address customer needs.  Accordingly,
it is possible that new  competitors or alliances  among  competitors may emerge
and  rapidly  acquire  significant  market  share.  In  addition,  some  of  our
competitors  may develop  services that are superior to, or have greater  market
acceptance than ours.

Our revenues may decline as a result of our client  agreements  which prevent us
from providing services to their competitors.

         We  sometimes  agree not to perform  services  for  competitors  of our
clients for limited periods of time, which have been as long as two years. These
non-compete  agreements reduce the number of our prospective  clients as well as
the number of  potential  sources of  revenue.  In  addition,  these  agreements
increase the  significance of our client  selection  process because many of our
clients  compete  in  markets  where  only a  limited  number of  entities  gain
meaningful  market share.  If we agree not to perform  services for a particular
client's  competitors  and our client fails to capture a significant  portion of
its market,  we are  unlikely  to receive  future  revenues  in that  particular
market.

Our efforts to develop brand awareness of our services may not be successful.

         An  important  element  of our  business  strategy  is to  develop  and
maintain widespread  awareness of the ESG brand name. To promote our brand name,
we plan to increase our advertising and marketing expenditures,  which may cause
our operating margins to decline.  Moreover, our brand may be closely associated
with the business success or failure of some of our high-profile  clients,  many
of whom are pursuing  unproven  business  models in  competitive  markets.  As a
result, if one of our high-profile  clients  experiences  great  difficulties or
fails, our brand may be damaged.  Our operating  margins and our growth rate may
decline if we fail to  successfully  promote and maintain our brand name as well
as if we incur significant expenses related to our brand.

If  businesses  do not  increase  their  use  of the  Internet  as a  means  for
conducting commerce, our revenues will be adversely affected.

         Our future success  depends on the increased  acceptance and use of the
Internet as a means for conducting  commerce.  In the future, we intend to focus
our services on the development and  implementation  of Internet  strategies and
solutions.  If Internet commerce does not continue to grow, or grows more slowly
than we  expect,  our  revenue  growth  may slow or  decline.  As a result,  our
business,  financial  condition  and  results of  operations  may be  materially
adversely  affected.  Consumers and businesses may also reject the Internet as a
viable medium for commerce for a number of reasons, including:

o    inadequate network infrastructure;
o    delays in the development of Internet enabling technologies and performance
     improvements;
o    delays in  the  development  or  adoption of new  standards  and  protocols
     required  to handle  increased  levels of Internet activity;
o    delays  in  the  development  of  security  and  authentication  technology
     necessary to effect secure  transmission of confidential information;
o    changes in, or insufficient  availability of,  telecommunications  services
     to support  the  Internet;  and
o    failure of  companies  to meet  their customers' expectations in delivering
     goods and services over the Internet.

We may not be able to effectively manage any continued growth.

         Our revenues have  increased  significantly  over the past three fiscal
years.  Continued  growth  could  place  a  significant  strain  on our  limited
personnel,  management,  financial  controls,  and other  resources.  Any future
expansion will require us to attract,  retain, train,  motivate,  and manage new
employees  successfully.  We would also need to  integrate  new  management  and
employees into our overall operations,  and continue to improve our operational,
financial,  and management  systems and controls and facilities.  Our failure to
manage any expansion  effectively  could have a material  adverse  effect on our
business, financial condition, or results of operations.

Industry related risks specific to ESG

Our  business  is  dependent  upon our  ability  to keep  pace  with the  latest
technological changes.

         Our market and the technologies  used by our clients are  characterized
by  rapid  technological  change.  Failure  to  respond  successfully  to  these
technological developments, or to respond in a timely or cost-effective way, may
result in serious  harm to our  business  and  operating  results.  We currently
derive,  and  expect to derive  in the  future,  a  substantial  portion  of our
revenues from  creating  eBusiness  systems that are based upon today's  leading
technologies  and that are  capable of  adapting  to future  technologies.  As a
result,  our success will depend, in part, on our ability to offer services that
keep pace with continuing changes in technology, evolving industry standards and
changing  client  preferences.  In  addition,  we must  hire,  train and  retain
technologically  adept  professionals  so that we can  continue  to fulfill  the
sophisticated needs of our clients.

The  professional  computer  services  industry  is  highly  competitive  and is
characterized by low barriers to entry. If we cannot  effectively  compete,  our
revenues may decline.

         The professional computer services market is intensely competitive.  We
expect competition to intensify as this market evolves.  Many of our competitors
have longer operating histories,  more clients,  longer relationships with their
clients,  greater brand or name recognition and significantly greater financial,
technical, marketing and public relations resources than we do. As a result, our
competitors may be in a stronger  position to respond quickly to new or emerging
technologies  and  changes in client  requirements.  They may also  develop  and
promote their products and services more effectively than we do.

         There  are  relatively  low  barriers  to entry  into the  professional
computer  services  market.  As a result,  we anticipate many new competitors to
pose a  threat  to our  existing  operations.  In  addition,  we do not  own any
patented  technology  that may prevent our competitors  from providing  services
similar to ours. As a result,  new and unknown market  entrants pose a threat to
our business.  Current or future  competitors may also develop or offer services
that  are  comparable  or  superior  to  ours  at  a  lower  price.  This  could
significantly decrease our revenues and the value of your investment.

The demand for our  services may diminish if  government  regulation  interferes
with the acceptance of the Internet and electronic commerce.

         Any new laws and regulations  applicable to the Internet and electronic
commerce  which may be adopted by federal,  state or foreign  governments  could
hinder  the growth of the  Internet  and  decrease  its  acceptance  as a viable
commercial  medium.  If this occurs,  companies  may decide in the future not to
pursue  Internet  initiatives,  thereby  decreasing  demand for our services.  A
decrease in the demand for our services would have a material  adverse effect on
our business, financial condition and results of operations.

We face significant competition in relatively new and changing markets.

         The markets for the  services  we provide  are highly  competitive.  We
believe that we  principally  compete with "Big 5"  consulting  firms,  Internet
professional  services firms, systems integration firms,  technology vendors and
internal information systems groups. Many of the companies that provide services
in our markets have  significantly  greater  financial,  technical and marketing
resources  than  we do and  generate  greater  revenues  and  have  better  name
recognition.  In addition,  because of the relatively low barriers to entry into
our markets we expect to face competition from new entrants. We believe that the
principal competitive factors in our markets include:

o    ability to integrate  strategy,  experience  modeling,  creative design and
     technology services;
o    quality of service, speed of delivery and price;
o    industry knowledge;
o    sophisticated project and program management capability; and
o    Internet technology expertise and talent.

We  believe  that our  ability to  compete  also  depends in part on a number of
competitive factors outside our control, including:

o    the ability of our  competitors to hire,  retain and motivate  professional
     staff;
o    the development by others of services or software that is competitive  with
     our solutions; and
o    the extent of our competitors' responsiveness to client needs.
<PAGE>

There can be no assurance  that we will be able to compete  successfully  in our
markets.

We may not have the right to resell or reuse  solutions  that we  developed  for
specific clients.

         A portion  of our  business  involves  the  development  of  technology
solutions or specific  client  engagements.  Ownership of these solutions is the
subject of negotiation and is frequently  assigned to the client.  Under certain
circumstances,  however,  we may be  permitted  to retain a license  for certain
uses. Some clients have prohibited us from marketing the applications  developed
for them for specified  periods of time or to specified  third parties and there
can be no assurance that clients will not demand similar or other  restrictions.
Issues  relating  to  the  ownership  of and  rights  to  use  solutions  can be
complicated  and there can be no  assurance  that  disputes  will not arise that
affect our ability to resell or reuse these  solutions.  Any  limitation  on our
ability  to resell or reuse a  solution  could  require  us to incur  additional
expenses to develop new solutions for future projects.

Our Risks and the Market for our Publicly Traded Securities

We depend on the services of our key personnel.

         Our  success  depends  to a  significant  degree on the  following  key
members of management:

o    B.R. "Bernie" Smedley, Chairman and Chief Executive Officer; and
o    Larry W. Whitfield, President, Software Technology, Inc.

         The loss of either one of these  members of our  management  team could
have a material adverse effect on our business,  financial condition, or results
of  operations.  We have an  employment,  non-competition,  and  confidentiality
agreement with Mr. Smedley. We also maintain a key man life insurance policy for
Mr. Smedley.

Shares held by our current  shareholders  may adversely  effect our Common Share
price.

         As of March 1, 2000, we had 5,715,411 Common Shares outstanding.  As of
March  1,  2000,  the  following  Common  Shares  are  freely  tradable  without
restriction or limitation  under the Securities Act of 1933 (the "Act"),  except
for the Common Shares purchased by "affiliates," as that term is defined in Rule
144 as promulgated under the Act:

o    the  2,346,272  Common  Shares  granted but not yet issued  under our stock
     option plans;
o    the 5,861 Common Shares issued under the employee stock purchase plan; and

         Our remaining  Common Shares may be sold in the public market,  subject
in some cases to the restrictions set forth in Rule 144 as promulgated under the
Act. We have  reserved  4,410,000  Common  Shares for  issuance  under our stock
option  plans.  We have issued  options to purchase a total of 2,763,822  Common
Shares  under  our  stock  option  plans,  of  which  2,346,272  have  yet to be
exercised.  Sales of  substantial  amounts  of our  Common  Shares in the public
markets,  pursuant to Rule 144 or otherwise,  or the  availability of our Common
Shares for sale could  adversely  affect the  prevailing  market  prices for our
Common  Shares and impair our ability to raise  additional  capital  through the
sale of equity  securities  in the future.  In the past,  our Common Shares have
traded at low volumes.  Future sale of our Common  Shares into the public market
could  have an  adverse  effect on the  prevailing  market  price of our  Common
Shares.

The market price of our Common Shares may be volatile.

         The  market  price  for   securities   of   technology   companies  has
historically  faced significant  volatility.  Like technology stocks in general,
the trading  price of our Common  Shares is  volatile.  In  addition,  the stock
market in recent years has experienced significant price and volume fluctuations
that often have been unrelated or disproportionate to the operating  performance
of  particular  companies.  The  following  factors may  influence our quarterly
common share trading price:

o    actual or anticipated operating results;
o    growth rates;
o    changes in estimates by analysts;
o    market conditions in the industry;
o    announcements by competitors;
o    regulatory actions; and
o    general economic conditions.
<PAGE>

Adverse changes in any of these items would likely result in a material  adverse
effect on the market price of our Common Shares.

Our quarterly operating results may vary significantly from quarter to quarter.

         Our  quarterly  revenues and earnings may  fluctuate as a result of the
following factors:

o    the number, size, and scope of our projects;
o    equipment purchases and other expenditures required for our business;
o    bid and proposal efforts undertaken;
o    delays in the award of projects;
o    employee productivity;
o    adequacy of provisions for losses;
o    accuracy  of  estimates of resources required to complete ongoing projects;
     and
o    general economic conditions.

         Demand for our  products  and  services in each of the markets we serve
can vary  significantly  from  quarter to quarter due to  revisions  in customer
budgets or schedules as well as other factors  beyond our control.  As a result,
our results of operations may fall below the expectations of securities analysts
and  investors in a particular  period.  Consequently,  the trading price of our
Common Shares may be materially adversely affected.

Future acquisitions may cause our management to encounter numerous problems.

         Our  management  tasks may be complicated  by future  acquisitions.  An
acquisition  may  require  us to  integrate  widely  dispersed  operations  with
distinct  corporate  cultures.  Such integration  efforts may not succeed or may
distract our management from satisfactorily  servicing our existing clients. Our
failure to manage  future  acquisitions  successfully  could harm our  operating
results.  Acquisition costs could also cause our quarterly  operating results to
vary significantly. Further, our shareholders would become diluted if we finance
future acquisitions by incurring debt or issuing additional equity securities.

Our anti-takeover provisions may hinder a potential change of control.

         Our Second  Amended  and  Restated  Certificate  of  Incorporation  and
Amended  and  Restated  ByLaws  contain  certain   provisions  that  reduce  the
probability of any change of control or acquisition:

o        our board of directors can issue blank check  preferred stock with such
         rights,  obligations and preferences as they may determine  without any
         further vote or action by the shareholders;

o        beginning  with the election of directors at our 1999 Annual Meeting of
         Shareholders,  our  board  was   classified  into  three  classes, each
         class of directors  serving for a period of three years, thus requiring
         at least two years for any change of control of our board; and

o        directors  may only be removed by holders of at least 60% of our Common
         Shares,  with  cause.

         Further,  in October  1998,  our board of  directors  adopted a "poison
pill"  shareholder  rights plan which may tend to  discourage a third party from
making an  unsolicited  proposal to acquire us which our board of directors does
not  approve,  even if such  acquisition  proposal  would be  beneficial  to our
shareholders.  As a  result,  shareholders  who  wish to  participate  in such a
transaction  may not have an  opportunity.  Under our  shareholder  rights plan,
preferred share purchase rights, which are attached to our Common Shares, may be
triggered upon an acquisition, or actions that result in the acquisition, of 15%
or more of our Common Shares by any person or group.  If triggered,  these share
purchase rights entitle our shareholders,  other than the acquiror, to purchase,
for the exercise price, our Common Shares having a market value of two times the
exercise price. In addition,  if a company acquires us in a business combination
transaction,  or if we sell more than 50% of our consolidated  assets or earning
power, these share purchase rights will entitle our shareholders, other than the
acquiror,  to purchase for the exercise  price,  the  acquiror's  Common  Shares
having a market value of two times the exercise  price.  Thus,  our  shareholder
rights plan, if triggered,  will cause substantial dilution to a person or group
attempting to acquire us on terms not approved by our board of directors.
<PAGE>

          In addition,  Section 203 of the Delaware General  Corporation Law and
our  stock  option  plans  may also  discourage,  delay or  prevent  a change in
control.

We may require additional capital resources to develop additional  technologies,
and these resources may not be available.

         We may need to raise additional funds, and we cannot be certain that we
will be able to obtain additional funds on favorable terms or at all. If we need
additional  capital and cannot raise it on acceptable  terms, we may not be able
to:

o    open  new  offices  in the  United  States  or  abroad;
o    create  additional market-specific  business  units;
o    enhance our  infrastructure  and leveragable assets;
o    hire, train and retain employees;
o    respond to competitive  pressures or unanticipated requirements; or
o    pursue acquisition opportunities.

Failure  to  obtain  additional  capital  resources  may  adversely  impact  our
long-term financial condition.

Our Common Shares are illiquid.

         Our Common Shares are thinly traded on the NASDAQ SmallCap Market. They
should  only be  purchased  by  investors  that can afford to lose their  entire
investment.  Our Common  Share  trading  price is highly  volatile and may trade
significantly  below the book value per Common  Share.  Until an orderly  market
develops,  if at all,  the  trading  price of our Common  Shares  may  fluctuate
significantly.   Prices  for  our  Common  Shares  will  be  determined  in  the
marketplace  and may be  influenced  by many  factors,  including  the depth and
liquidity of the market,  investor  perception of our business and our industry,
and general economic and market conditions.

We may encounter Year 2000 risks.

         Historically,  installed  computer  systems and software  products were
coded to accept only  two-digit  entries in the date code field.  To distinguish
21st century dates from 20th century dates,  these date code fields must be able
to accept  four-digit  entries.  We have  evaluated our  information  technology
infrastructure for Year 2000 compliance and made certain modifications.  To this
date, we have not  experienced any material  systems  disruptions as a result of
Year 2000 issues and we do not anticipate  such material  disruption.  We cannot
assure you,  however,  that  unanticipated or undiscovered  Year 2000 compliance
problems  would not have a material  adverse  effect on our business,  financial
condition,  or results of operations.  In addition,  we have limited information
concerning  the compliance  status of our customers and suppliers.  In the event
that any of our significant customers or third-party suppliers are not Year 2000
compliant,  our financial condition or results of operations could be materially
adversely affected.

Item 2.  Properties

           Our corporate  headquarters are located in Melbourne,  Florida.  This
area is commonly  referred to as the "Space  Coast"  because of its proximity to
NASA's Kennedy Space Center. Exigent,  through STI, entered into a 10 year lease
expiring  on  February  28,  2007 to occupy a 30,000  square  foot  building  in
Melbourne,  FL. This  building  houses our corporate  headquarters,  our product
development facility and FotoTag. STI also leases an adjacent 29,000 square foot
building under a ten-year lease expiring  December 1, 2005. This facility houses
many of our technical employees.

         We also have three offices in the greater Washington,  D.C. area. These
offices are predominantly  staffed with technical  employees.  Exigent,  through
STI,  renewed our existing  lease of 15,296 square feet,  located in Alexandria,
Virginia, for five years expiring on August 31, 2003. In December 1998, Exigent,
through STI,  occupied an additional  leased  building of  approximately  11,188
square feet, located in Chantilly, Virginia, under a five-year lease expiring on
November  30, 2003.  We have  entered  into a lease for an expanded  facility in
Chantilly, Virginia to meet the growth requirements for our anticipated business
in this area.

         We also lease  office  space in LaPlata,  Maryland;  Colorado  Springs,
Colorado; Aurora, Colorado;  Boulder,  Colorado;  Charlotte, North Carolina; and
Mesa, Arizona.

         We believe that our occupancy needs will be met through our next fiscal
year.  Due to the  nature  of  our  business,  there  are  no  special  facility
requirements to consider,  other than security requirements placed on certain of
our  facilities,  given that software  development  can be conducted in standard
office  space and we incur  minimal  manufacturing  requirements  because  it is
mostly outsourced.

Item 3.  Legal Proceedings

         We may, from time to time, be involved in litigation  incidental to the
conduct of our  business.  We are not  currently a party to any  material  legal
proceedings.

Item 4.  Submission of Matters to a Vote of Security Holders

         During the fourth quarter of the fiscal year covered by this report, we
did  not  submit  any  matters  to a  vote  of  security  holders,  through  the
solicitation of proxies or otherwise.

PART II

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

          Until  February 26, 1999 our Common  Shares and Warrants were reported
on the NASDAQ  Electronic  Bulletin Board  ("Bulletin  Board") under the symbols
XGNT and XGNTW.  On March 1, 1999,  our Common Shares and Warrants began trading
on the Nasdaq Small Cap Market.  Our Common  Shares and Warrants are also traded
on the Chicago Stock Exchange under the symbols XNT and XNTW, respectively.  The
Warrants  traded as specified on both  Exchanges  until  expiring on January 30,
2000. There is no established trading market for the Company's Class A Preferred
Shares. (See Risk Factors - Risks Specific to the Company and the Market for its
Publicly Traded Securities).

         The  following  table  represents  the high and low bid  prices for our
Common  Shares and Warrants  for each quarter of our fiscal year ended  December
31, 1999, and each of the second,  third and fourth  quarters of the fiscal year
ended December 31, 1998, as reported in the Nasdaq daily report:

    1st Quarter              $4.00      $2.94        $1.5625    $0.6875


         As of March 1, 2000, we have approximately  1,110 holders of our Common
Shares  (based  upon  the  number  of  record  holders).  This  number  excludes
shareholders  whose Common Shares are held in nominee or street name by brokers.
Our Warrants  expired on January 30,  2000.  Prior to  expiration,  798,560 were
exercised at a price of $3.00 per share,  and we raised a total of $2,395,680 in
capital. As of March 1, 2000 we have no Warrant holders.

         Our  Board of  Directors  determined  during  our  fiscal  years  ended
December 31, 1998, and 1999 that dividends  would not be paid in the foreseeable
future.  The Board  determined  that our resources  should be devoted to funding
acquisitions, product development and operations.

Item 7.  Management's Discussion and Analysis of Financial Condition and Results
of Operations

         We had a challenging  year with respect to revenue and earnings growth.
At the beginning of the year, we expected  record-breaking  commercial satellite
business from STI due to our support of the Teledesic program.  Our expectations
changed,  however,  when Teledesic  experienced numerous delays. As a result, we
ceased working on the Motorola Strategic Agreement. We decided that we could not
recover  our  complete  investment  in  Teledesic  and  that  it was  no  longer
financially prudent to continue to carry that asset on our books.  Consequently,
we  wrote  off  approximately  $1,000,000  and  decided  to close  our  facility
supporting  the  project  in  Mesa,  Arizona.  Further,  Iridium,  our  flagship
constellation and revenue-producing  project, filed for reorganization under the
U.S.  Bankruptcy Laws during the third quarter.  As a result of these facts, our
commercial  satellite business declined  significantly.  Based on the decreasing
STI  government  space  services  business,  and  our  projections  of  revenues
therefrom,  we decided to  replace  our  decreasing  commercial  and  government
satellite  service  revenue with IT and  Enterprise  Engineering  (EE)  business
thereby utilizing our core tracking and control engineering resources.

         We were able to continue to grow our overall revenues in 1999 year over
year,  continue to invest in new product  development,  maintain  positive  cash
flows and  initiate an  acquisition  program for a commercial  IT business.  Our
first  acquisition was successfully  completed in December 1999 when we acquired
GEC, an Oracle services provider.

         We developed a tracking and control COTS product family (OS/COMET) that
was designed to manage a single  Geostationery  Earth Orbit ("GEO") satellite or
several  hundred  satellites  in a  constellation.  No company  has ever  before
demonstrated that capability.

         Our management  believes that these financial  changes  position us for
greater revenues and earnings growth in the future.

         We have  changed  the last day of our  fiscal  year from  January 31 to
December 31. Hence,  our fiscal year 1998B was an eleven-month  period ending on
December 31, 1998.

Liquidity

         As of December 31, 1999 and  December  31,  1998,  our ratio of current
assets to current  liabilities was 1.2 and 1.7,  respectively.  This decrease is
due to our  December  9,  1999  acquisition  of GEC.  Current  liabilities  were
increased by approximately $1,700,000 in connection with this acquisition.

         Our cash portfolio (cash and cash equivalents)  increased  $144,398 for
the fiscal year ended  December 31, 1999.  This increase was due to cash used in
investing  activities  of  $4,176,873  offset  by  cash  provided  by  operating
activities  of  $2,388,710   and  cash  provided  by  financing   activities  of
$1,932,561.  By  comparison,  our cash  portfolio  decreased  $3,210,538 for the
eleven  months ended  December 31, 1998.  This  decrease was due to cash used in
investing  activities  of  $4,900,806  and by operating  activities of $204,878,
offset by cash provided by financing activities of $1,895,146.  The cash used in
investing activities was due to a $2,144,253 investment in software development,
a $35,020  investment in our facilities and capital  equipment and net cash paid
for GEC of  $1,912,484.  The  acquisition  of GEC was booked  using the purchase
method  of  accounting  resulting  in  goodwill  of  $2,861,416,  which  will be
amortized  over ten years.  The cash used in investing  activities in the eleven
months ended  December 31, 1998 was  attributable  to an  investment in software
development  of $3,905,349  and an investment in Company  facilities and capital
equipment of $1,002,041.

         In our fiscal  years ended  December  31,  1999,  December 31, 1998 and
January 31, 1998, we invested  $35,020,  $1,002,041,  and  $1,306,693 in capital
assets,  respectively.  The  expenditure in the eleven months ended December 31,
1998  was due  largely  to the  completion  of  remodeling  and  furnishing  our
facilities as well as the installation of a wide area network serving all of our
principal facilities.  The expenditure in the fiscal year ended January 31, 1998
was due  primarily to an investment  made in computing  resources to support the
demonstration of our products and capabilities in an integrated  control center.
The expenditures in prior fiscal years were made to support programs and for the
modernization of office equipment. In the fiscal year ended January 31, 1998, we
decided to lease new computer  equipment and furnishings for our facilities.  We
continued  to lease new items  through the fiscal year ended  December 31, 1999.
Capital for  equipment  purchases is expected to remain  stable for the next two
fiscal  years  because  of our recent  computer  acquisition  and  modernization
efforts.  We will continue our policy of leasing  resources for office computing
needs and furnishings.
<PAGE>

         During our fiscal years ended December 31, 1999,  December 31, 1998 and
January 31, 1998, we spent $2,144,253, $3,905,349 and $1,149,685,  respectively,
in capitalized  software  development  costs to develop new products  considered
essential in maintaining a strong market  position in the satellite  command and
control industry as well as to test the market for enhanced airport security.

         Cash  provided  by  financing  activities  for the fiscal  years  ended
December 31,  1999,  December  31,  1998,  and January 31, 1998 was  $1,932,561,
$1,895,146, and $413,759,  respectively. This was comprised of $575,641 borrowed
against a line of credit to finance  operations,  $203,504  borrowed through two
capital  lease lines with  Oliver-Allen  Corporation,  and  $1,000,000  borrowed
through Huntington Bank to finance the acquisition of GEC, offset by $325,939 in
principal  payments on long-term debt. In addition,  $479,355 was raised through
the exercise of stock options and Warrants.

         For the fiscal  years ended  December 31, 1999 and 1998 and January 31,
1998, our Board of Directors  determined not to pay any  shareholder  dividends,
but instead to use cash for acquisitions, product development and operations.

         In our fiscal  years ended  December  31,  1999,  December 31, 1998 and
January 31, 1998  principal  payments on  long-term  debt  amounted to $325,939,
$345,506  and  $382,108,  respectively.  On August  12,  1999,  we  obtained  an
additional  $2,000,000 to our existing line of credit with  Huntington  National
Bank.  As of December 31, 1999 and  December  31, 1998,  we had a line of credit
with Huntington National Bank of $5,000,000 and $3,000,000,  respectively. As of
December 31, 1999 and 1998, draws against the line of credit were $2,386,734 and
$1,811,093,  respectively.  All accounts receivable,  equipment,  furniture, and
fixtures of STI are pledged as collateral  against  amounts  borrowed  under the
line of credit.

         Our  management  believes  that  capital in addition to that  available
through  operations  and the available  line of credit will be necessary to fund
our plans for expansion  and growth  during our next fiscal year and beyond.  We
may seek debt or equity financing.  However, there can be no assurance that such
financing  will be available on  acceptable  terms,  if at all, or that adequate
amounts of financing will be obtained.

Analysis of Operations

Overview

         Our current contract base provides  sufficient  backlog to maintain our
operations  through June,  2000. As of December 31, 1999, our funded backlog for
commercial and government contracts  respectively was $2,607,352 and $3,215,294.
We invested in excess of  $9,000,000  during the last two years in our  software
product  OS/COMET.  We believe this investment  facilitated many of our contract
awards.  We are  committed  to  maintain  OS/COMET  during  fiscal year 2000 and
beyond.

         The commercial  constellation  business has been stationary through the
year ended December 31, 1999, as commercial  projects worked to finance both the
development and the deployment of their satellites.

         In the fourth  quarter ended  December 31, 1999,  Exigent,  through its
acquisition of GEC, began expanding its range of business activities into the IT
business and formed ESG for this purpose.  This expansion is expected to provide
new customer  opportunities  in both the  government  as well as the  commercial
sectors.

         We expect  demand  for  software  engineers  to  provide  new  customer
opportunities, but this demand places a premium on efforts to retain our current
workforce. (See Risk Factors - Highly Competitive Market for Computer Services).
As with all companies in our industry,  this places  additional  pressure on our
overall  payroll  costs.  We believe  that our benefits  package is  competitive
within our  industry  and this  should  help to recruit  workers  and retain our
current workforce. As our indirect costs funding benefits increase,  pressure is
placed on our indirect rates. We believe that maintaining  superior  benefits is
critical while the demand for software engineers remains high. We are constantly
struggling with the need to minimize costs while  maintaining  superior employee
benefits.

Comparison of Years Ended  December 31, 1999,  December 31, 1998 and January 31,
1998

         As of  the  fiscal  year  ended  December  31,  1999,  our  sales  were
$36,151,278, up 16.1% from sales of $31,139,083 for the eleven-month fiscal year
ended  December 31, 1998.  Sales were up 6.0% after  adjusting for the fact that
the period ended December 31, 1998  consisted of only eleven  months.  Our sales
for the eleven-month  fiscal year ended December 31, 1998,  decreased 12.9% from
sales of  $35,748,719  for our fiscal year ended January 31, 1998. The breakdown
between government and commercial sales for these periods is as follows:

               Year ended           Eleven months             Year ended
                12/31/99            ended 12/31/98              1/31/98
             ---------------        ---------------        --------------
Government   $  31,498,070     87%  $  24,698,289     79%  $  23,113,510     65%
Commercial       4,653,208     13%      6,440,794     21%     12,635,209     35%
             --------------- -----  ---------------  ----  --------------   ----
             $  36,151,278    100%  $  31,139,083    100%   $ 35,748,719    100%
             =============== =====  ===============  ====  ==============   ====

         These sales reflect a 87% to 13% government to commercial  split in our
fiscal  year ended  December  31,  1999,  compared  to a 79% to 21% split in our
fiscal  year ended  December  31, 1998 and a 65% to 35% split in our fiscal year
ended January 31, 1998. Government contract revenue increased in our fiscal year
ended December 31, 1999 due to our obtaining  additional  from the NRL and other
government entities,  while we completed a major commercial sector contract. Our
sales in its fiscal year ended December 31, 1998 increased from our sales in the
fiscal year ended  January 31, 1998 due largely to  obtaining a contract  with a
new government agency as well as sales of OS/Comet.

         Gross profit as a percentage of sales  decreased to 22.0%  ($7,963,175)
for the fiscal  year ended  December  31, 1999 from 24.9%  ($7,738,362)  for the
fiscal year ended  December  31,  1998.  This  decrease  was due  primarily to a
write-down of work  performed with respect to the Strategic  Alliance  Agreement
with Motorola. Upon complete review of the circumstances, this was determined to
be an impaired asset and we wrote down approximately  $1,000,000. In addition, a
complete  review of the FotoTag asset  resulted in an adjustment in the carrying
value of the asset of  approximately  $380,000.  Gross profit as a percentage of
sales  for  our  fiscal  year  ended   January  31,  1998  was  26.1%  of  sales
($9,326,933).  As a  result  of the  aforementioned  writeoffs,  we were  not in
compliance  with  certain  financial  covenants  under our credit  agreement  at
December 31, 1999. Huntington Bank has waived this event of default.

</TABLE>

     General  and  administrative  expenses  ("G&A")  for the fiscal  year ended
December 31, 1999 were $8,617,157,  26.3% or $1,793,959  higher than expenses of
$6,823,198  for the eleven  months ended  December  31,  1998.  After taking the
shortened  fiscal year into account,  our expenses were 4.4% or $360,799  higher
than for the eleven  months  ended  December 31, 1998.  This  increase  resulted
primarily from staffing a Chief  Technical  Officer  ($450,000),  staffing other
positions  which  had not  previously  been  staffed  such as a Chief  Financial
Office,  expenses  associated  with financial  advisory  services,  and expenses
associated with the acquisition of GEC ($550,000),  in addition to the increased
marketing effort  associated with the new products  introduced during the fiscal
year ended December 31, 1999 ($180,000). General and administrative expenses for
the eleven  months  ended  December 31, 1998 were  $6,823,198,  3.2% or $226,872
lower than our  expenses of  $7,050,070  for the fiscal  year ended  January 31,
1998.  Again,  taking into  consideration  the eleven-month  year, versus a full
twelve-month  year, G&A expenses were 17.1% or $1,206,288  higher than those for
the fiscal year ended January 31, 1998.  This increase  resulted  primarily from
$250,000 in costs associated with a potential  acquisition,  an increase in rent
expense  of  $200,000,  and the  complete  staffing  of  corporate  officers  of
approximately $500,000.

         We incurred a net loss of  $478,665  (1.3% of sales) in the fiscal year
ended  December  31,  1999,  which was down  significantly  from a net income of
$418,160 in the eleven months ended December 31, 1998. We attribute this loss to
a one-time charge for two impaired assets equal to approximately  $1,400,000. In
addition, there was a significant reduction in commercial revenue as development
on a major  commercial  effort was completed in the eleven months ended December
31, 1998. We continued  maintenance  on the Iridium  contract,  but at a greatly
reduced rate from our previous  rate. We also  attribute our loss to a reduction
in  commercial  constellation  projects as a result of financing  and  marketing
issues.  The net income in the eleven months ended  December 31, 1998  decreased
significantly  from the fiscal year ended January 31, 1998 of  $1,345,429.  This
decrease  was  due  primarily  to  the  reduction  in  commercial  constellation
projects.

Outlook

         This section captioned  "Outlook" and other parts of this Annual Report
on Form 10-K include certain  forward-looking  statements  within the meaning of
the federal  securities  laws.  Actual  results and the  occurrence or timing of
certain  events  could  differ  materially  from those  projected in any of such
forward-looking statements due to a number of factors, including those set forth
below and elsewhere in this Form 10-K. See "Other Forward-Looking Statements."

         Diversification  and Long  Term  Growth.  We expect  to  diversify  our
business  through  sales of COTS  products  in both  commercial  and  government
markets and expand our information  technology  offerings in both the commercial
as well as the  government  markets.  Our first  step in this  strategy  was the
acquisition of GEC.  Additionally,  we currently plan to seek  opportunities for
long  term  growth  through  additional  acquisitions,  sales  of  products  for
commercial applications, and leveraging our existing technologies and products.


<PAGE>


         Product  Development.  We  are  developing  new  products  and  product
offerings, including the next generation of OS/COMET, the Active Tracking Engine
("ATE") and the OS/ICC.  We plan to  investigate  other new product  development
opportunities as part of its effort to expand its product offerings and market.

Year 2000 Issues

         Some  existing  computer  programs  will be unable to  recognize  dates
properly in the Year 2000  ("Y2K") and beyond.  During  1997,  we  conducted  an
informal study of our products, systems and operations, including products under
development,  to improve our business  functionality,  to identify  those of our
computer  hardware,  software and process  control  systems that do not properly
recognize  dates after  December  31,  1999,  and those that are linked to third
parties' systems.  Based on this informal study, we recognized that the OS/COMET
product   required  certain   modifications  to  become  Y2K  compliant.   Those
modifications  have been made to the software  and are  available in the current
release,  Version 3.5.  Communications  with these  certain  third parties whose
computer  systems'  functionality  could  adversely  impact our  operation  were
completed during the third quarter of 1999. These communications will facilitate
coordination of any necessary Y2K conversions and will, additionally,  permit us
to determine  the extent to which we may be  vulnerable  to the failure of third
parties  to  address  their  own Y2K  issues.  We  completed  our  review of all
desktop-computing  resources  during the third quarter of 1999.  Due to the fact
that we believe we have secured  sufficient  resources to address the Y2K issue,
as it relates to our own  computer  systems  and  certain  third  parties  whose
computer  systems'  functionality  could adversely  impact us, we do not believe
that  contingency  planning is warranted at this time.  We believe that Y2K will
not have a material and adverse impact on our desktop-computing resources.

         The costs of our Y2K  compliance  efforts  are being  funded  with cash
flows from operations.  Some of these costs relate solely to the modification of
existing  systems,  while others are for new systems that will improve  business
functionality.  In total,  these  costs  are not  expected  to be  substantially
different  from the  normal,  recurring  costs  that are  incurred  for  systems
development  and  implementation,  in part due to the  reallocation  of internal
resources and the deferral of other projects.  As a result,  these costs are not
expected to have a material  adverse effect on our overall results of operations
or cash flows.

         The  assessment  of our  Y2K  compliance  costs  constitutes  our  best
estimate.  These estimates were based upon numerous assumptions regarding future
events,  including  assumptions  as to the  continued  availability  of  certain
resources, and, in particular,  personnel with expertise in this area, and as to
the ability of such  personnel to locate and either  re-program or replace,  and
test, all affected  computer  hardware,  software and process control systems in
accordance with our planned schedule.  We cannot therefore  guarantee that these
estimates will prove  accurate,  and actual  results could differ  significantly
from those estimated if these assumptions prove inaccurate.

         Based upon  progress to date,  however,  we believe that it is unlikely
that the  foregoing  factors will cause actual  results to differ  significantly
from those  estimated.  As to our  systems  linked to third  parties,  we cannot
guarantee  that such systems are  Y2K-compliant  and will be compliant  within a
timely manner. Additionally,  there can be no guarantee that our important third
party vendors will successfully and timely test,  reprogram and/or replace,  and
test, all of their computer hardware, software and process control systems.

Report of Independent Auditors

Board of Directors and Stockholders
Exigent International, Inc.

We  have  audited  the  accompanying  consolidated  balance  sheets  of  Exigent
International,  Inc.  as  of  December  31,  1999  and  1998,  and  the  related
consolidated  statements of operations,  stockholders' equity and cash flows for
the year ended  December 31, 1999 and the eleven months 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 auditing standards generally accepted
in the United States. 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 financial  statements  referred to above present fairly, in
all  material   respects,   the  consolidated   financial  position  of  Exigent
International,  Inc. at December 31, 1999 and 1998, and the consolidated results
of its  operations  and its cash flows for the year ended  December 31, 1999 and
the eleven  months ended  December  31,  1998,  in  conformity  with  accounting
principles generally accepted in the United States.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BUSINESS - Exigent  International,  Inc.  (Exigent or the Company) was formed on
March 25, 1996 as a holding company. On January 30, 1997, it acquired all of the
outstanding  stock of Software  Technology,  Inc. (STI) in exchange for stock of
Exigent,  the "Exchange".  STI,  therefore,  became a wholly owned subsidiary of
Exigent.  STI,  formed  in  1978  in  Florida,  provides  systems  and  software
engineering  services  and  commercial  off the  shelf  products  for  real-time
command,  control,  and data  acquisition  systems for  government  and industry
throughout  the U.S.  STI also  produces  OS/COMET  - a  commercially  available
command and control development and support system. In March 1997, FotoTag, Inc.
(FotoTag) was formed as a wholly owned  subsidiary  of Exigent.  FotoTag Inc., a
Delaware corporation,  was created as a subsidiary of Exigent in 1997 to provide
the structure for  concentration  on tracking and control  system  solutions for
international high technology applications. The subsidiary's first product, also
called FotoTag(R), is used for tracking airport and airline passengers and their
checked bags.

In 1999, Exigent Solutions Group ("ESG") was formed as a wholly owned subsidiary
to provide integrated management consulting,  design and development of Internet
commerce   solutions,   implementation  and  integration  of  packaged  software
solutions,  design and development of custom software solutions,  implementation
of ERP systems and production  support.  ESG began offering  Enterprise Resource
Planning   (ERP)   implementation   services  in  December  1999  following  its
acquisition of all of the  outstanding  shares of GEC North America  Corporation
("GEC"),  a  Charlotte,   NC-based   consulting  and  systems  integration  firm
recognized as a leader in implementing ERP solutions using Oracle  Applications.
ESG's  services  now  include  integrated  management  consulting,   design  and
development of Internet commerce  solutions,  implementation  and integration of
packaged  software   solutions,   design  and  development  of  custom  software
solutions,  implementation  of ERP  systems  and  production  support.  ESG also
includes the products  developed by  MiddleWare  Solutions,  Inc., a corporation
formed in 1998 which  develops  inexpensive,  high-performance  message-oriented
middleware  products,  and  distributes  them  directly to the end-user over the
Internet or on CD through the mail.

CONSOLIDATION  POLICY  -  The  accompanying  consolidated  financial  statements
include  the  accounts  of  the  Company  and  its  wholly  owned  subsidiaries.
Intercompany transactions and balances have been eliminated in consolidation.

FISCAL  YEAR - The  financial  statements  for 1999 and 1998  include the twelve
months of operations ended December 31, 1999,  (fiscal "1999"),  and January 31,
1998, (fiscal "1998"), respectively.  During 1998 the Company changed its fiscal
year end from January 31 to December 31. Accordingly,  the financial  statements
for the period  ended  December 31, 1998  (fiscal  "1998B")  include only eleven

                           EXIGENT INTERNATIONAL, INC.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

REVENUE  AND COST  RECOGNITION  - The  Company  recognizes  revenues on time and
material  and cost plus fixed fee  contracts  as time is expended  and costs are
incurred.  The fee on cost plus fixed fee and award fee  contracts is recognized
ratably  over total costs as they are  incurred.  Revenues  and costs from fixed
price contracts are recognized on the percentage-of-completion  method, measured
by the percentage of total costs incurred to date to total  estimated  costs for
each contract. This method is used, as management considers total expended costs
to be the best available measure of progress on these contracts.

Contract  costs include all direct  material and labor costs and those  indirect
costs related to contract performance such as indirect labor, supplies, repairs,
and depreciation costs.

Certain  general  and  administrative   expenses  (including  bid  and  proposal
expenses) allowable in accordance with U.S. Government procurement practices are
included in contract costs where they are identifiable with contract revenue.

Adjustments to cost estimates are made  periodically,  and losses expected to be
incurred on contracts in progress are charged to  operations  in the period such
losses are determined.  The aggregate of costs incurred and income recognized on
uncompleted contracts in excess of related billings is shown as a current asset,
and the  aggregate  of billings on  uncompleted  contracts  in excess of related
costs incurred and income recognized is shown as a current liability.

The  Company  sells  a  number  of  software  products.  Generally,  revenue  is
recognized  upon  shipment  of the  software.  After  the sale,  if  significant
obligations remain or significant  uncertainties exist about customer acceptance
of the software,  revenue is deferred until the obligations are satisfied or the
uncertainties are resolved.  When  collectibility of the receivable is in doubt,
revenue is recognized  under the  installment  method or cost  recovery  method.
Revenue from  software  services is  recognized  as the  services are  provided.
Revenue from software  maintenance  contracts is  recognized on a  straight-line
basis over the life of the contract.

CASH EQUIVALENTS - For purposes of the statement of cash flows, cash equivalents
include  time  deposits,  certificates  of deposit,  and all highly  liquid debt
instruments with original maturities of three months or less.

PROPERTY  AND  EQUIPMENT  -  The  cost  of  property,  plant  and  equipment  is
depreciated over the estimated useful lives of the related assets.  Depreciation
is computed on the  straight-line  method;  accelerated cost recovery system and
the modified accelerated cost recovery system as appropriate.

GOODWILL - Goodwill  represents  the excess of the purchase  price over the fair
value  of  the   identifiable   net  assets  acquired  and  is  amortized  on  a
straight-line   basis  over  the  expected  period  of  benefit  of  ten  years.
Accumulated  amortization  was $13,196 at December  31, 1999.  Periodically  the
Company   evaluates  the  goodwill  for  impairment  and  estimates  the  future
undiscounted  cash flows of the  acquired  business to ensure that the  carrying
value has not been impaired,

ADVERTISING COSTS - The costs of advertising are expensed as incurred. For 1999,
1998B,  and 1998,  advertising  costs  included  in general  and  administrative
expenses were $188,795, $196,036, and $223,142, respectively.

PATENTS - Legal  costs  incurred  related to  obtaining  patents on  proprietary
products and technology are  capitalized  and amortized over the estimated lives
of the patents. Accumulated amortization was $0 at December 31, 1999.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

SOFTWARE DEVELOPMENT COSTS - In accordance with SFAS No. 86, "Accounting for the
Costs of  Computer  Software  to be Sold,  Leased or  Otherwise  Marketed,"  the
Company  capitalizes the direct costs and allocated indirect expenses associated
with the  development  of  software  products.  Initial  costs  are  charged  to
operations as research prior to the development of a detailed  program design or
a working  model.  Costs  incurred  subsequent  to the  product's  release,  and
research and development  performed as contractual  requirements  are charged to
operations.

AMORTIZATION - The costs of capitalized  software development are amortized over
their  estimated  useful  lives of two years.  Amortization  is  computed on the
straight-line  method. The Company periodically reviews the capitalized software
development cost to ensure that future anticipated gross revenues related to the
products exceeds the unamortized cost.

EARNINGS  (LOSS) PER SHARE - Earnings (loss) per share is computed and presented
in accordance with SFAS No. 128, "Earnings per Share".

COMPREHENSIVE  INCOME - There is no  difference  between  net income  (loss) and
comprehensive income (loss) for any of the periods presented.

NEW  ACCOUNTING  PRONOUNCEMENTS  -  SFAS  No.  133,  Accounting  for  Derivative
Instruments  and Hedging  Activities is effective for financial  statements  for
fiscal years beginning after June 15, 2000. SFAS 133 requires the recognition of
all  derivatives  in  the  consolidated   balance  sheet  as  either  assets  or
liabilities  measured as fair value.  The Company does not  anticipate  that the
adoption  of this  Statement  will have a  significant  effect on its results of
operations or financial position.

DISCLOSURE  ABOUT FAIR VALUE OF  FINANCIAL  INSTRUMENTS  - The  carrying  amount
reported  in  the  balance  sheets  for  cash  and  cash  equivalents,  accounts
receivable,  accounts  payable  and  accrued  expenses  approximates  fair value
because of the immediate or short-term  maturity of these instruments.  The fair
value of indebtedness  approximates  its carrying value as interest rates on the
debt are market rates.

CONCENTRATIONS OF CREDIT RISK - Financial  instruments that potentially  subject
the Company to  concentrations  of credit risk  consists  primarily of temporary
cash  investments.  The Company  places its temporary  cash  investments  with a
financial  institution.  The amount of credit  exposure  in excess of  federally
insured  limits  at  December  31,  1999  and 1998 was  $596,000  and  $766,000,
respectively.

Most of the Company's  revenues are derived primarily from products and services
related to satellite  command and control.  Should the demand for such  services
take a substantial  downturn and the number of satellites deployed is materially
reduced, the Company's business opportunities would be limited significantly.

USE OF ESTIMATES - The  preparation of financial  statements in conformity  with
generally accepted  accounting  principles requires management to make estimates
and assumptions  that affect certain  reported amounts of assets and liabilities
and disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.

The   Company    recognizes    revenue   on   certain    contracts   using   the
percentage-of-completion  method,  which is based upon total estimated costs for
each contract.  The estimate is subject to change as the work progresses on each
contract.

STOCK BASED  COMPENSATION  - The Company  follows APB 25  "Accounting  for Stock
Issued to Employees",  and related  interpretations  in accounting for its stock
based  compensation  rather than the alternative fair value accounting  provided
under SFAS No. 123, "Accounting for Stock-Based Compensation".

IMPAIRMENT  OF  LONG-LIVED  ASSETS - In the event that  facts and  circumstances
indicate  that the cost of assets may be  impaired,  an  evaluation  of recovery
would  be  performed.  If  an  evaluation  is  required,  the  estimated  future
undiscounted  cash flows  associated  with the asset  would be  compared  to the
asset's  carrying  amount  to  determine  if a write  down to  market  value  or
discounted cash flow value is required.

NOTE 4 - LINE OF CREDIT

On August 12, 1999,  STI  completed a $2,000,000  increase in its line of credit
with a bank supplementing the existing  $3,000,000 line. As of December 31, 1999
and  1998,  the  outstanding   draws  against  the  lines  were  $2,386,734  and
$1,811,093, respectively. The outstanding balances accrue interest at LIBOR plus
2.5%. The interest rate at December 31, 1999 and December 31, 1998 was 8.97% and
7.56%,  respectively.  The line of credit  requires  that the  Company  maintain
various financial covenants including leverage,  working capital,  current ratio
and debt coverage requirements. Advances under the line of credit are based on a
borrowing base computation.  All accounts receivable,  equipment,  furniture and
fixtures of STI are pledged as collateral on the line of credit.

The Company was not in  compliance  with the working  capital and current  ratio
covenants at December  31, 1999.  The Bank has waived these events of default at
December 31, 1999 and the Company expects that it is reasonably possible it will
be in compliance with these covenants at measurement dates during 2000.

The weighted average interest rate on short-term  borrowings during 1999, 1998B,
and 1998 were 8.19%, 7.56% and 8.25%, respectively.

1998B and 1998. For fiscal 1999,  1998B, and 1998, the amount of pension expense
was $1,970,364, $1,763,632, and $1,381,023, respectively.

The Company also sponsors a profit-sharing  plan which allows  substantially all
full-time  employees to defer  compensation under Section 401(k) of the Internal
Revenue Code and the employer to  electively  contribute  to the plan.  Employer
contributions  to the plan are made at the discretion of the Board of Directors.

Directors.  Full-time employees who have attained the age of twenty-one (21) are
eligible to  participate  in the plan.  Contributions  to the plan are allocated
annually  to  eligible  employees  proportionate  to  their  compensation,   not
including  overtime and bonuses.  Employee stock  ownership  plan  contributions
charged to  operations  and  applied to  overhead  amounted to $0 and $ 405,343,

of the total issued and outstanding  stock,  respectively,  at December 31, 1999
and December 31, 1998.

Dividends paid on the ESOP shares,  as well as other shares are considered to be
reductions in retained earnings.  The shares owned by the ESOP are considered to
be  outstanding  shares  and  therefore  included  in  the  earnings  per  share
calculation.

1999,  1998B,  and  1998,  respectively.  The  shares'  fair  market  value  was
determined  based on the  trading  value of  Common  Shares  of the  Company  at
December 31, 1999 and 1998.

the Board of Directors at quarterly  vesting date. The Committee may at any time
discontinue  granting  awards under the Plan (except to Independent  Directors).
The Board of Directors may at any time,  prospectively or  retroactively,  amend
the Plan,  including  the  provisions  with  respect  to  grants to  Independent
Directors,  or for any purpose  that may at the time be permitted by law, or may

NOTE 19 - ACQUISITION

On December 9, 1999, Exigent completed the acquisition of GEC by exchanging cash
and subordinated promissory notes for all of the voting and non-voting shares of
GEC common stock.  The  acquisition of the assets and  liabilities was accounted
for using the purchase method of accounting  whereby the  consideration  paid of
$3,525,694 was allocated  based on the fair values of the assets and liabilities
acquired with the excess  consideration  over the fair value of tangible  assets
recorded as intangible assets (goodwill).  The purchase price, the allocation of
the  purchase  price and the  amortization  period of the  goodwill are detailed

The operating  results of GEC have been included in the consolidated  results of
operations from the date of the acquisition.  On a pro forma basis as if the GEC
acquisition had taken place at the beginning of 1999,  consolidated net revenue,
net income (loss),  and earnings  (loss) per share would have been  $41,280,289,
($331,135), and ($0.07),  respectively, for the year ended December 31, 1999. On
a pro forma  basis as if the  acquisition  had taken place at the  beginning  of
1998,  consolidated net revenue,  net income,  and earnings per share would have
been $35,940,476,  $651,232, and $0.13 per share,  respectively,  for the period
ended December 31, 1998. Such pro forma amounts are not  necessarily  indicative
of what the actual results would have been if the acquisition had been effective
at the beginning of the 1998 and 1999 fiscal years and are not audited.

years and the fiscal year ended  January  31,  1998,  Hoyman,  Dobson & Company,
P.A.,  continues to provide us with various accounting  services.  The directors
determined a change was  warranted  because the new  certifying  accountant  has
greater national resources to serve our growing needs.

         The principal  accountant's report on the financial  statements for the
previous two years has not contained an adverse opinion or disclaimer of opinion
nor were such reports  qualified or modified as to  uncertainty,  audit scope or
accounting  principles.  We have not had any  disagreements  with our  principle
accountants  on any matter of  accounting  principles  or  practices,  financial
statement  disclosure or auditing scope or procedure  during its two most recent
fiscal  years or since then.  During our two most recent  fiscal  years or since
then,  we have  not  been  advised  by our  principal  accountant:  (i) that the
internal controls necessary for us to develop reliable financial  information do
not exist; (ii) that information has come to the accountant's attention that has
led the accountant to no longer be able to rely on management's  representations
or that have made the accountant  unwilling to be associated  with the financial
statements prepared by management; (iii) of the need to expand significantly the
scope of its audit, or that information has come to the  accountant's  attention
that if further  investigated may materially  impact the fairness or reliability
of  either  a  previously  issued  audit  report  or  the  underlying  financial
statements, or the financial statements covering a period subsequent to the date
of the most recent financial  statements covered by an audit report or cause the
accountant  to be  unwilling  to  rely  on  management's  representations  or be
associated with the Company's financial statements; or (iv) that information has
come to the accountant's  attention that the accountant has concluded materially
impacts the fairness or reliability  of either a previously  issued audit report
or the underlying financial statements, or the financial statements issued or to
be issued covering the fiscal periods  subsequent to the date of the most recent
financial statements covered by an audit report.

         By  letter  dated  March  27,  1998,  Hoyman,  Dobson &  Company,  P.A.
confirmed  its  agreement  with the  foregoing,  as  disclosed  in Item 4 of our
Current  Report on Form 8-K filed with the  Securities  and Exchange  Commission
(the "Commission") on March 30, 1998.
This letter is attached as Exhibit 16 to the March 30, 1998, Current Report Form

                                      TERM

4.1   Lease Term. The Term shall commence on the Commencement Date and expire at
midnight on the Expiration  Date. If Substantial  Completion of the Premises has
not occurred on the date set forth in Article 1 as the  Commencement  Date, then
the  Commencement  Date shall be the date of Substantial  Completion;  provided,
that if Tenant uses or accepts the Premises before Substantial Completion or the
date set forth in Article 1 as the Commencement Date, then the Commencement Date
shall be the date upon which Tenant uses or accepts the Premises (i.e., the date
on which Tenant begins to move furniture,  furnishings,  inventory, equipment or
trade fixtures into the Premises).  In such event,  the Expiration Date shall be
adjusted accordingly so that the period of the Term is not changed. If requested
by  Landlord,  Tenant  shall  within  fifteen  (15) days of such  request sign a
declaration  acknowledging  the Commencement Date and the Expiration Date in the
form attached  hereto and made a part hereof as Exhibit C. If Landlord,  for any
reason  other  than  Tenant  Delay (as  defined in the Work  Agreement),  cannot
deliver  the  Premises  in  condition  for  occupancy  by Tenant to conduct  its
business therein on the Commencement  Date specified in Article 1 of this Lease,
rent shall abate for the period between said Commencement Date and the time when
Landlord  can deliver  such  possession.  In the event the  Premises  are not in
condition for occupancy ninety (90) days after the  Commencement  Date specified
in  Article 1 hereof for any reason  other than Force  Majeure  events or Tenant
Delay,  the Tenant shall have the sole right to cancel or terminate  this Lease,
without any further  obligation on its part,  upon giving  written notice of its
intention  to do so (which  notice shall  specify  that it is given  pursuant to
Section 4.1 of this Lease),  provided  Tenant's  option to cancel and  terminate
this Lease must be exercised by written notice to Landlord, served no later than
thirty  (30) days after such right to cancel  and  terminate  arises.  If Tenant
shall give such notice,  then this Lease and the Term and estate hereby  granted
shall terminate on the date of the giving of such notice with the same effect as
if such date were the date herein  before  specified  for the  expiration of the
Term of this Lease and  neither  party  shall  have any  further  obligation  to
perform hereunder.

equal monthly  installments,  in advance,  without  demand,  notice,  deduction,
offset or counterclaim except as and to the extent expressly provided herein, on
or  before  the  first day of each and every  calendar  month  during  the Term;
provided,  however,  that the installment of the Base Rent payable for the first
full calendar month of the Term (and, if the Commencement  Date occurs on a date
other than on the first day of a calendar  month,  Base Rent  prorated from such
date until the first day of the following month) shall be due and payable on the
full  execution  and delivery of this Lease.  Tenant shall pay the Base Rent and

other  manner as  Landlord  from time to time  specifies  by  written  notice to
Tenant.  Any  payment  made by Tenant to Landlord on account of Base Rent may be
credited by Landlord to the payment of any Base Rent then past due before  being
credited to Base Rent currently due.

5.3   Additional  Rent.  All sums payable by Tenant under this Lease, other than
Base Rent,  shall be deemed  "Additional  Rent," and, unless otherwise set forth
herein, shall be payable in the same manner as set forth above for Base Rent.

5.4   Late Payment. If during any period of twelve consecutive months during the
Term  Tenant  shall fail on more than two  occasions  to pay any Rent within ten
(10) days after such Rent  becomes due and  payable,  then on the third and each
subsequent  occasion  (a) Tenant  shall pay to  Landlord  a late  charge of five
percent  (5%) of the  amount of such  overdue  Rent,  and (b) any such late Rent
payment  shall bear  interest  from the date such Rent became due and payable to
the date of payment thereof by Tenant at the Interest Rate. Such late charge and
interest  shall be due and payable  within five (5) business  days after written
demand from Landlord is received by Tenant.

5.5   Advance Rent.Simultaneously with the execution of this Lease, Tenant shall
deposit with Landlord the Advance Rent in cash, as payment,  in advance, of Base
Rent due under this Lease. The Advance Rent shall serve Landlord as security for
Tenant's  performance of its obligations under this Lease until such time as the
first  monthly  installment  of Base Rent  becomes due.  When the first  monthly
installment  of Base Rent  becomes  due,  Landlord  shall apply the Advance Rent
against  such  installment,  and  thereafter  against  each  additional  monthly
installment  of Base Rent due under this  Lease,  until such time as the Advance
Rent is exhausted.

                                   ARTICLE 6
                               SECURITY DEPOSIT

deposit   with  Landlord   the  Security   Deposit  in   cash,  which  shall  be
held by Landlord,  with interest for the account of Tenant, as security, for the
performance of Tenant's obligations and covenants under this Lease. All interest
accrued on the Security  Deposit  shall be added to and be  considered a part of
the Security  Deposit,  for  disposition  as set forth  herein.  For purposes of
reporting  interest  income,  Tenant's  Federal  tax  identification  number  is
59-1826343.  The Security  Deposit is not an advance rental deposit or a measure
of  Landlord's  damages in case of an Event of  Default.  If an Event of Default
shall occur beyond any  applicable  notice and cure period or if Tenant fails to
surrender  the Premises in the condition  required by this Lease,  Landlord may,
and without  prejudice to any other  remedy  which  Landlord may have on account
thereof,  to apply  all or any  portion  of the  Security  Deposit  to cure such
default or to remedy the condition of the  Premises.  If Landlord so applies the
Security  Deposit or any portion  thereof before the Expiration  Date or earlier
termination of this Lease, Tenant shall deposit with Landlord,  upon demand, the
amount  necessary to restore the Security  Deposit to its  original  amount.  If
Landlord shall sell or transfer its interest in the Building or the Complex,  or
in the event of a foreclosure,  Landlord shall transfer the Security  Deposit to

<PAGE>

such purchaser or transferee, in which event Tenant shall look solely to the new
landlord for the return of the Security  Deposit,  Landlord  thereupon  shall be
released  from all  liability to Tenant for the return of the Security  Deposit,
and the new owner shall be liable for Tenant's  Security  Deposit.  Although the
Security Deposit shall be deemed the property of Landlord, any remaining balance
of the  Security.  Deposit  shall be  returned  to Tenant at such time after the
Expiration  Date or  earlier  termination  of this  Lease  that all of  Tenant's
obligations under this Lease have been fulfilled. Landlord shall conduct a "Post
Move-Out  Inspection"  of the  Premises  within  fifteen  (15)  days  after  the
Expiration Date or earlier termination of this Lease.

Term, Tenant shall pay to Landlord,  as Additional Rent, Tenant's  Proportionate
Share of the amount by which the  Operating  Expenses  during each calendar year
exceed the  Operating  Expenses  during  the Base Year.  If the first day of the
second  Lease  Year or the  Expiration  Date are  other  than the first day of a
calendar year, then Tenant's  Proportionate Share of Operating Expenses shall be
adjusted to reflect the actual period of occupancy during such calendar year.

7.2   Operating Expenses Defined.

Expenses);

          (9)    Accounting,  consulting  and  legal fees (whether  attributable
to Landlord's in-house attorneys or paralegals);

          (10)    Any  additional  services  not provided to the Building at the
Commencement Date but thereafter provided by Landlord  as  Landlord  shall  deem
necessary or desirable;

          (11)    All condominium dues and related  charges and all assessments,
whether general, special or otherwise, levied  against Landlord, the Building or
Complex  pursuant to any condominium regime or any declaration or other  instru-
ment affecting the Building or any part or component thereof;

          (12)    All computer rentals for energy management or  security  moni-
toring systems, if any;

          (13)    Any   capital  improvements  made  to  the  Building after the
Commencement  Date  (other than those made for the  addition of rentable  square
footage to the Building or for the sole benefit or a Building tenant pursuant to
its lease),  the  cost  of which shall be  amortized  over  the  useful  life of
such  expenditure  according  to  generally  acceptable  accounting   principles
("GAAP"),  together with interest on the unamortized balance of such cost at the
Interest Rate or such higher rate as may  have  been  paid  by Landlord on funds
borrowed  for  the  purposes of constructing said capital  improvements but only
to  the  extent  that  such  capital  improvement is (i) intended by Landlord to
result in the reduction of Operating Expenses but only to  the  extent  that the

<PAGE>

same results in an actual reduction of Tenant's costs,  (ii) necessary or advis-
able to comply with  Legal  Requirements. or (iii)  necessary  or  advisable  to
comply  with  insurance  requirements  or  recommendations of Landlord's insurer
or Mortgagee;

          (14)    The cost of any transportation  program fees, mass transporta-
tion  fees  or  similar  fees  charged  or  assessed  by  any   governmental  or
quasi-governmental entity or pursuant to any Legal Requirements; and

          (15)    Any  payments  made  by  the  Landlord  under  any easement or
license agreement, declaration, restrictive covenant or instrument pertaining to
the payment of sharing of costs among property owners.

      (b) If during any calendar year  (including  the Base Year), the average
occupancy rate for the Building is less than ninety-five percent (95%) or Land-
lord is not supplying services to 95% of the rentable  area of the  Building at
any time during any such  calendar year,  Operating  Expenses for such calendar
year shall be deemed to include all additional costs and  expenses of ownership,
maintenance,  management and operation of the Building which Landlord determines
that  it  would  have  paid  or  incurred  during any such calendar year if such
average  occupancy  rate  for  the Building had been 95% and had  Landlord  been
supplying services to 95% of the rentable square feet of the Building throughout
such  calendar  year.  In  the event  that after the Base Year Landlord provides
services,  the cost of which would be included in Operating  Expenses, that were
not provided during the Base Year, then the cost of such services shall be added
to the Base Year "gross-up" as if such services existed and were provided on the
Commencement Date. If any amounts comprising Operating Expenses are incurred not
just with respect to the office area of the  Building,  but also with respect to
the retail area of the Building, if any, then Landlord  shall  endeavor  in good
faith and  use its  reasonable  efforts to allocate  such  amounts  between  the
office and retail areas of the Building. Such allocation shall be made on a fair
and  equitable  basis,  based  on  the  usage of  or  benefits received from the
service, utility or item in question.  It is not  the intent of this  provision,
commonly  referred  to as a "gross up" clause,  to  permit  Landlord  to  charge
Tenant  for  any Operating Expenses attributable to unoccupied space, or to seek
reimbursement  from Tenant for costs the Landlord never  incurred.  Rather,  the
intent of this provision is to allow Landlord  to  recover  only those increases
in  Operating  Expenses  properly  attributable  to  the occupied  space in  the
Building,  and  is  thus  designed  to calculate  the  actual cost of  providing
variable Operating Expense services (i.e.,  Operating Expenses that are affected
by variations in occupancy levels, such as char  service)  to the  rentable area
of the  Building  receiving  such service.

7.3   Exclusions from Operating Expenses.

      (a)     Operating Expenses shall not include the following:

              (1) Legal fees, space planners' fees, real estate brokers' leasing
commissions,   advertising    expenses   and   all  other   costs   incurred  in
connection with the original or future leasing of space in the Building;

              (2) Costs  and  expenses  of  alterations or  improvements  of the
Premises or the leasehold premises of other individual tenants in the Building;
<PAGE>

              (3)   Costs of  correcting  defects  in, or   inadequacy  of,  the
design or construction of the Building or the materials used in the construction
of  the  Building  or the  equipment  or  appurtenances  thereto  to  the extent
covered by  warranties  and recovered by Landlord;

              (4)  Depreciation,  interest  and  principal payments on mortgages

other than  amortization  of  and  the interest factor attributable to permitted
capital improvements;

              (5) Costs  and  expenses  associated  with  the  operation  of the

and  legal  matters,  costs  of  defending   any  lawsuits  with  any  Mortgagee
(except to the extent the actions of Tenant or any other tenant may be in issue)
costs of selling or financing  any of Landlord's  interest  in  the Building and
outside fees paid in connection with disputes with other tenants;

              (6) Costs  and   expenses   directly   resulting  from  the  gross
negligence  or  willful  misconduct  of  Landlord  or  its  Agents to the extent
provable by Tenant;

              (8)     Landlord's income taxes;

              (9) Landlord's costs of any service sold or provided to any tenant
or occupant of the Building for which  Landlord is  reimbursed  as an additional
charge or rental over and above the base rent and escalations  payable under the
lease or  occupancy  agreement  with that  tenant or other  occupant  (including
after-hours HVAC costs or over-standard electrical consumption costs incurred by
other  tenants or occupants or excess  insurance  costs  arising from a tenant's
specific use or equipment) and costs of services  provided to some tenants,  but
not to Tenant;

              (10) The initial cost of construction of the Building;

              (11) Expenses   for  repairs or  replacements  to the extent  such
expenses are covered by and reimbursed to Landlord by virtue of warranties  from
contractors or suppliers;

              (12) The cost of any  item of  service  or  repair  to the  extent
covered by and reimbursed to Landlord under any warranty,  guaranty or insurance
policy maintained or held by Landlord;

failure to make timely  payments  of its  obligations,  unless  such  failure is
caused by Tenant's conduct;

existing as of the Commencement Date;

              (18)  Compensation of officers or executives of Landlord above the
level of property manager;

              (20) Costs  arising from the presence of Hazardous  Materials  (as
defined in Article 26) in, about or below the Building or Complex; and

              (21) Reserves for repairs, maintenance and replacements.

                   Landlord  shall not  collect  more  than one  hundred
percent (100%) of the Operating Expenses actually incurred
by Landlord and shall not recover any items of cost more than once.

      (b) All Operating Expenses  shall be reduced by the amount of insurance or
other  reimbursement,  recoupment,  payment,  discount or allowance  received by
Landlord.  Landlord  shall, at all times during the entire term and its options,
operate,  manage,  maintain and repair the Building in a lawful,  efficient  and
businesslike  manner in  accordance  with sound  property  management  practices
consistent with comparable first class office buildings in the northern Virginia
metropolitan  area. Tenant shall only be liable for Operating Expenses which are
attributable to term of this Lease or such time as Tenant occupies the Premises,
whichever is greater.

7.4 Estimated Payments. Landlord shall submit to Tenant, before the beginning of
each calendar year, a statement of Landlord's estimate of the Operating Expenses
payable by Tenant  during  such  calendar  year.  In  addition to the Base Rent,
Tenant  shall pay to  Landlord  on or before the first day of each month  during
such  calendar  year an amount  equal to  one-twelfth  (1/12)  of the  estimated
Operating  Expenses  payable  by Tenant for such  calendar  year as set forth in
Landlord's  statement.  If Landlord fails to give Tenant notice of its estimated
payments  due under this  Article  for any  calendar  year,  then  Tenant  shall
continue making monthly  estimated  payments in accordance with the estimate for
the previous  calendar  year until a new  estimate is provided by  Landlord.  If
Landlord determines that, because of unexpected  increases in Operating Expenses
or other  reasons,  Landlord's  estimate of the Operating  Expenses was too low,

<PAGE>

then  Landlord  shall have the right to give a new  statement  of the  estimated
Operating Expenses due from Tenant for such calendar year or the balance thereof
and to bill  Tenant  for any  deficiency  which  may have  accrued  during  such
calendar year, and Tenant shall thereafter pay monthly estimated  payments based
on such new statement.

7.5 Actual  Operating  Expenses.  Within one hundred twenty (120) days after the
end of each calendar year, Landlord shall submit a reasonably detailed statement
to Tenant  showing the actual  Operating  Expenses  for such  calendar  year and
Tenant's  Proportionate  Share of the  amount by which such  Operating  Expenses
exceed the  Operating  Expenses  during the Base Year;  provided that failure by
Landlord to deliver such  statement  within the time  specified  above shall not
relieve Tenant of any of its  obligations  hereunder.  If for any calendar year,
Tenant's estimated monthly payments exceed Tenant's  Proportionate  Share of the
amount by which the actual Operating  Expenses for such calendar year exceed the
Operating  Expenses  during the Base Year,  then  Landlord  shall give  Tenant a
credit in the amount of the overpayment toward Tenant's next monthly payments of
estimated  Operating  Expenses.  If for any  calendar  year  Tenant's  estimated
monthly  payments are less than  Tenant's  Proportionate  Share of the amount by
which the actual Operating  Expenses for such calendar year exceed the Operating
Expenses  during the Base Year,  then Tenant  shall pay the total amount of such
deficiency  to Landlord  within  thirty (30) days after receipt of the statement
from  Landlord.   Landlord's  and  Tenant's  obligations  with  respect  to  any
overpayment or underpayment  of Operating  Expenses shall survive the expiration
or earlier termination of this Lease.

7.6 Tenant's Right to Audit.  In the event of any good faith dispute  concerning
the  charges or  computation  of the  amounts  payable to  Landlord  pursuant to
Articles 7.4 and 7.5 herein,  Tenant shall pay into escrow, in an escrow account
and with an escrow agent both reasonably acceptable to Landlord,  the portion of
the amount in dispute  pending the  resolution of the dispute,  and such payment
shall be without  prejudice  to  Tenant's  right to continue  to  challenge  the
disputed  charges or computation.  All fees,  charges and expenses of the escrow
agent shall be paid by Tenant at it's sole cost and  expense.  In no event shall
Tenant be permitted to make  payments of Base Rent, as specified in Article 1.7,
into such escrow account. In the event Tenant shall dispute the amount set forth
in  Landlord's  statement as described in Article 7.5 herein and Tenant pays the
full amount set forth in Landlord's  reconciliation  statement with any disputed
amount paid into such escrow  account  then,  Tenant  shall have the right,  not
later  than  ninety  (90) days  following  receipt of such  statement,  to cause
Landlord's  books and records with respect to the preceding  calendar year to be
audited and/or  inspected by Tenant itself or with the assistance of accountants
or other  consultants,  and who shall not be compensated on a contingency basis.
Such audit shall occur upon not less than twenty (20) days prior written  notice
to  Landlord,  at  Landlord's  place  of  business  or the  actual  location  of
Landlord's  books and records if different  from  Landlord's  place of business,
during Landlord's normal business hours.  Subject to Landlord's right to dispute
the results of Tenant's  audit as  hereinafter  described,  the amounts  payable
under this Article by Landlord to Tenant or by Tenant to  Landlord,  as the case
may be,  shall be  appropriately  adjusted on the basis of such  audit.  If such
audit  discloses a liability for further  refund by Landlord to Tenant in excess
of five percent (5%) of the payments previously made by Tenant for such calendar
year, then, subject to Landlord's right to dispute the results of Tenant's audit
as  hereinafter  described,  (a) the  actual  out-of-pocket  cost of such  audit
incurred by Tenant shall be borne by Landlord  and paid within  thirty (30) days

<PAGE>

of demand from Tenant and (b) Tenant and/or its  representatives  shall have the
right to  audit/inspect  Landlords  books and records  for the year  immediately
preceding  the prior  audit year for any  potential  excess  payments by Tenant;
otherwise, the cost of such audit shall be borne by Tenant.  Notwithstanding the
foregoing,  in no event shall  Landlord's cost for such audit (not including any
excess payment by Tenant) exceed Three Thousand  Dollars  ($3,000).  If Tenant's
audit  discloses  a liability  for  further  refund by Landlord to Tenant of one
percent (1%) or less or a liability for further payment by Tenant,  then in that
event the actual  out-of-pocket  cost to respond to Tenant's  audit  incurred by
Landlord (including reasonable  consultants' and attorneys' fees), not to exceed
Three Thousand Dollars ($3,000), shall be borne by Tenant and paid within thirty
(30) days of demand from Landlord.  In the event that the Landlord  disputes the
results of the Tenant's  audit,  Landlord shall notify Tenant within thirty (30)
days of delivery of the results of the Tenant's audit  together with  reasonably
detailed documentation related thereto. If Landlord disputes the Tenant's audit,
Landlord  shall within said 30-day period,  designate an  independent  Certified
Public Accounting firm from one of the "Big-Six" (i.e., Arthur Anderson & Co. or
similar  company)  and said  firm  shall  review  the  Tenant's  audit  and,  if
necessary,  shall  re-audit the  Landlord's  books and records and issue a final
report within ninety (90) days of the expiration of said 30-day  period.  Tenant
shall fully  cooperate  and  instruct  its auditor to fully  cooperate  with the
review  conducted by the Big-Six firm. The findings of the Big-Six firm shall be
conclusive  and binding on the parties  hereto as it relates to the statement at
issue.  In the event that the Big-Six firm's report  confirms the Tenant's audit
then the  Landlord  shall pay the cost of the  Big-Six  audit  which shall be in
addition  to any  obligation  Landlord  may  have to pay  Tenant's  expenses  as
aforesaid.  In the event that the report  discloses a  liability  by Landlord to
Tenant of less than the amount indicated in Landlord's  statement,  then in that
event the  Tenant  shall pay the cost of the  Big-Six  audit  which  shall be in
addition  to any  obligation  Tenant  may  have to pay  Landlord's  expenses  as
aforesaid.  If  Tenant  shall  not  request  an  audit  in  accordance  with the
provisions  of this  Article  within  ninety (90) days of receipt of  Landlord's
reconciliation  statement of actual Operating Expenses,  such statement shall be
conclusive and binding upon Landlord and Tenant.

                                   ARTICLE 8
                                     TAXES

8.1 Tenant's  Proportionate Share of Real Estate Taxes.  Commencing on the first
day of the second  Lease Year and  continuing  throughout  the  remainder of the
Term, Tenant shall pay to Landlord,  as Additional Rent, Tenant's  Proportionate
Share of the amount by which Real Estate Taxes during each  calendar year exceed
Real Estate  Taxes  during the Base Year.  If the first day of the second  Lease
Year or the  Expiration  Date are other than the first day of a  calendar  year,
then  Tenant's  Proportionate  Share of Real  Estate  Taxes shall be adjusted to
reflect the actual period of occupancy during such calendar year.

8.2  Definition  of Real Estate  Taxes.  As used  herein,  the term "Real Estate
Taxes"  shall mean all taxes and  assessments,  general or special,  ordinary or
extraordinary,  foreseen  or  unforeseen,  assessed,  levied or  imposed  by any
governmental  authority  upon the  Complex  and upon  the  fixtures,  machinery,
equipment or systems in, upon or used in connection  with any of the  foregoing,
and the rental, revenue or receipts derived therefrom,  under the current or any
future  taxation or assessment  system or  modification  of,  supplement  to, or
substitute  for such  system.  Real  Estate  Taxes  also  shall  include-special

<PAGE>

assessments which are in the nature of or in substitution for real estate taxes,
including road improvement  assessments,  special use area  assessments,  school
district  assessment,  vault space  rentals and any business,  professional  and
occupational license tax payable by Landlord in connection with the Building. If
at any time the  method  of  taxation  prevailing  on the date  hereof  shall be
altered so that in lieu of, as a  substitute  for or in addition to the whole or
any part of the taxes now levied or assessed,  there shall be levied or assessed
any of the  following,  then the same  shall be  included  within the term "Real
Estate Taxes" hereunder:  a tax, assessment,  levy fee or other charge (i) on or
measured by the rents  received from the Building or the Complex,  (ii) measured
by or based in whole or in part upon the  Building  or the  Complex  and imposed
upon Landlord, or (iii) measured by the rent payable by Tenant under this Lease.
Except to the extent provided in the preceding sentence, Real Estate Taxes shall
not include any franchise, corporation, income or profit tax calculated upon the
Landlord's net income.  In no event shall any inheritance,  estate,  succession,
transfer,  gift tax, or capital levy be included in Real Estate Taxes.  Further,
for the purposes of this Article, Real Estate Taxes shall include the reasonable
expenses  (including  attorneys'  fees)  incurred by Landlord in  challenging or
obtaining  or  attempting  to  obtain a  reduction  of such Real  Estate  Taxes,
regardless  of the outcome of such  challenge.  Notwithstanding  the  foregoing,
Landlord  shall  have no  obligation  to  challenge  Real  Estate  Taxes  unless
requested by tenants in the Building representing fifty percent (50%) or more of
the rentable space in the Building. If as a result of any such challenge,  a tax
refund is made to Landlord,  then the amount of such refund less the expenses of
the  challenge  shall be deducted  from Real Estate  Taxes due in the Lease Year
such refund applies,  and if any portion of such refund applied to a tax year in
which  Tenant has paid Real Estate  Taxes,  Landlord  shall  refund to Tenant an
amount equal to Tenant's  pro-rata  share of such reduction of Real Estate Taxes
as has  actually  been paid by Tenant to  Landlord  in the tax year to which the
reduction applies.  Landlord's obligation to refund to Tenant its pro-rata share
of such reduction shall survive the expiration or termination of this Lease. The
Real Estate Taxes  Statement shall  reasonably  detail the Real Estate Taxes for
such calendar year. Landlord further covenants and agrees to pay all Real Estate
Taxes no later than the date on which such taxes are due and payable.

8.3  Estimated  and  Actual  Payments.  Landlord  shall  charge  Tenant  for its
Proportionate  Share of Real Estate  Taxes and Tenant  shall pay such charges in
accordance  with  the  procedures  established  under  Articles  7.4 and 7.5 for
payment of Operating Expenses.

                                    PARKING

9.1 Parking  Spaces..  During the Term, and at no additional  fee,  Tenant shall
have the exclusive right to use the Reserved Spaces and the non-exclusive  right
to use the  unreserved  portion  of the  Parking  Facilities  to the  extent  of
Tenant's unreserved Parking Space Allotment.

9.2 Reserved  Spaces.  Landlord,  at its cost,  shall keep the  Reserved  Spaces
marked with the words "Reserved,  Software Technology" to designate the Reserved
Spaces.  Landlord  shall have no  obligation  to police the use of the  Reserved
Spaces by persons other than Tenant and its Agents.
<PAGE>

9.3 Rules and  Regulations  for Parking.  Tenant  shall abide by any  reasonable
rules or regulations for the use of the Parking  Facilities which may be adopted
by the  Landlord  for the general  safety,  care,  cleanliness  and order of the
Parking Facilities,  the Building and the users thereof.  Upon notice to Tenant,
such  rules  and  regulations  may be  changed  from  time to  time as  Landlord
reasonably deems necessary. Landlord may assign and reassign, from time to time,
particular  parking spaces  (except for the Reserved  Spaces) for use by persons
selected by Landlord.

9.4 Changes to Parking  Facilities.  Landlord shall have the right, from time to
time,  with Tenant's  consent not to be  unreasonably  withheld,  conditioned or
delayed,  to change,  alter, add to,  temporarily  close or otherwise affect the
Parking Facilities;  provided,  that Landlord endeavor in good faith and use its
reasonable   efforts  to  minimize  any  material   interference  with  Tenant's
beneficial  use of the Premises.  Tenant shall not use more parking  spaces than
the Parking Space Allotment.

                                   ARTICLE 10
                                       USE

10.1 General. Tenant shall occupy the Premises solely for the Permitted Use. The
Premises  shall  not be used for any other  purpose  without  the prior  written
consent  of  Landlord  which  consent  shall  not  be   unreasonably   withheld,
conditioned or delayed.  Tenant shall comply, at Tenant's expense,  with (i) all
Legal  Requirements,  and (ii)  any  reasonable  requests  of  Mortgagee  or any
insurance company providing coverage with respect to the Premises.  Tenant shall
not use or occupy the  Premises in any manner that is unlawful or  dangerous  or
that shall constitute an unreasonable annoyance or a violation of the Covenants.

10.2  Tenant's  Personal  Property.  Tenant  shall pay  before  delinquency  any
business,  rent or other tax or fee that is now or hereafter assessed or imposed
upon Tenant's use or occupancy of the Premises, the conduct of Tenant's business
in the  Premises  or  Tenant's  Property.  If any such tax or fee is  enacted or
altered so that such tax or fee is imposed upon  Landlord or so that Landlord is
responsible for collection or payment thereof,  then Tenant shall pay the amount
of such tax or fee as Additional Rent.

                            ASSIGNMENT AND SUBLETTING

11.1 Consent. Tenant shall not assign, transfer,  mortgage or otherwise encumber
this  Lease or sublet or rent (or  permit a third  party,  to occupy or use) the
Premises,  or any part  thereof,  nor shall any  assignment  or transfer of this
Lease or the right of  occupancy  hereunder  be effected by  operation of law or
otherwise,  without the prior written  consent of Landlord,  which consent shall
not be unreasonably withheld or delayed (any such valid assignment,  sublease or
any of the other  foregoing  shall  sometimes  be  hereinafter  referred to as a
"transfer").  For purposes of the foregoing prohibitions,  a transfer at any one
time or from  time to time of twenty  percent  (20%) or more of an  interest  in
Tenant  (whether  stock,  partnership  interest  or other form of  ownership  or
control) by any  person(s) or entity  (ties)  having an interest in ownership or
control of Tenant on the date hereof shall be deemed to be an assignment of this

Lease.  Any assignment,  encumbrance,  or sublease  without  Landlord's  written
consent shall be voidable by Landlord and, at Landlord's election, constitute an
Event of Default hereunder.  Notwithstanding the foregoing, in any event, Tenant
shall be strictly  prohibited  from  assigning or subletting  its interest in or
rights under this Lease in any way during the final Lease Year of the Term. This
Article 11.1 is subject to Article 11.6.

11.2  Landlord's  Options.  If at any time or from time to time during the Term,
Tenant  desires to effect a transfer,  Tenant shall deliver to Landlord  written
notice  ("Transfer  Notice")  setting  forth  the terms  and  provisions  of the
proposed transfer and the identity of the proposed assignee,  sublessee or other
transferee  (sometimes referred to hereinafter as a "Transferee").  Tenant shall
also deliver to Landlord with the Transfer Notice, a current financial statement
for the  Transferee  and such  other  information  as  Landlord  may  reasonably
request. Landlord shall have the option, exercisable by written notice delivered
to Tenant within ten (10) days after Landlord's  receipt of the Transfer Notice,
such financial statements and other information, either to:

      (a)      approve or disapprove such transfer; or

      (b)  terminate this Lease with respect to the entire  Premises (or, in the
case of a proposed sublease,  only that portion of the Premises which the Tenant
has requested to Sublease),  which  termination  shall be effective  thirty (30)
days after Tenant's receipt of Landlord's notice;  provided,  however, that this
clause (b) shall not apply  unless the  proposed  transfer  (either by itself or
when taken  together  with all prior  transfers  hereunder)  would result in the
transfer of 50% or more of the  Premises.  Should  Landlord  attempt to exercise
such right to  terminate  this Lease  provided for under this clause then Tenant
shall have the right,  exercisable  within five (5) business  days of receipt of
landlords intent to terminate this Lease, to withdraw the transfer  request,  in
which event Landlord's exercise of its termination right under this clause shall
be null and void.

In the event that  Landlord  refuses to consent  to a  sublease,  assignment  or
transfer,  then Landlord shall  simultaneously  provide Tenant with a reasonably
detailed  written  explanation  for  such  refusal.  Landlord  will  provide  to
subtenants and assignees all rights and services provided for in this Lease.

11.3  Assignment  or Sublet  Premium.  If  Landlord  approves an  assignment  or
subletting of all or any portion of the  Premises,  Tenant shall pay to Landlord
as Additional  Rent,  as and when  received by Tenant,  an amount equal to fifty
percent  (50%) of the  difference  between  (i) all sums paid by or on behalf of
such  assignee or  subtenant  under the  assignment  or  sublease,  and (ii) the
Monthly  Base  Rent and  Additional  Rent paid by Tenant  under  this  Lease and
attributable  to the portion of the Premises  assigned or sublet;  provided that
Tenant  shall be entitled to deduct from such  premium  prior to such payment to
Landlord  all  reasonable  costs and  expenses  actually  incurred  by Tenant in
procuring such assignee or subtenant, such as but not limited to brokerage fees,
advertising,  legal  expenses  incurred in  connection  with such  assignment or
sublease,  other economic concessions granted to such assignee or subtenant, and
expenses of such  improvements  constructed in such assigned or subleased  space
and actually  paid for by Tenant (such costs and expenses are referred to herein
as "Tenant Transfer Costs").
<PAGE>

11.4 Release.  No transfer  shall release Tenant of Tenant's  obligations  under
this  Lease or alter  the  primary  liability  of  Tenant to pay the rent and to
perform all other obligations to be performed by Tenant  hereunder.  In the case
of a transfer  consisting  of an  assignment  and not a  sublease,  if  Landlord
consents to the proposed  assignment,  Landlord may require that any  Transferee
remit  directly  to  Landlord  on a monthly  basis all monies due Tenant by said
Transferee;  provided  that, in the event that (a) all sums paid by or on behalf
of such assignee under the assignment shall exceed (b) the Monthly Base Rent and
Additional Rent paid by Tenant under this Lease and  attributable to the portion
of the Premises  assigned  (such excess,  if any, of (a) over (b) is referred to
herein as the "Excess Amount"),  then to the extent that such Excess Amounts are
received  by  Landlord,  (i)  Landlord  shall pay to Tenant  all of such  Excess
Amounts until and to the extent the such  aggregate  amount of all such payments
so made by Landlord  to Tenant  shall be equal to all of Tenant  Transfer  Costs
incurred in connection with such assignment, and (ii) thereafter, Landlord shall
pay to Tenant fifty percent (50%) of all such Excess Amounts.  The acceptance of
rent by  Landlord  from any other  person  shall not be deemed to be a waiver by
Landlord of any provision hereof.  Consent by Landlord to one transfer shall not
be deemed consent to any subsequent  transfer.  If an Event of Default occurs by
any Transferee of Tenant or any successor of Tenant in the performance of any of
the terms  hereof,  Landlord may proceed  directly  against  Tenant  without the
necessity of exhausting  remedies against such Transferee or successor.  In such
event (but only in the case of a Transferee constituting an assignee of, but not
a sublessee under,  this Lease,  Landlord shall not exercise any right or remedy
which it holds under any  provision of this Lease or  applicable  law unless and
until:  (1) the Landlord  has given  written  notice to the Tenant;  and (2) the
Tenant has failed  (i) if such  Event of  Default  consists  of a failure to pay
money,  within five (5) business days after written  notice is received,  to pay
such  sums  due to  Landlord,  or (ii) if such  Event  of  Default  consists  of
something other than a failure to pay money,  within thirty (30) days thereafter
actively,  diligently  and in good  faith to begin to cure such Event of Default
and to  continue  thereafter  to do so  until it is fully  cured.  Landlord  may
consent to subsequent  assignments  of the Lease or sublettings or amendments or
modifications to the Lease with assignees of Tenant,  without  notifying Tenant,
or any successor of Tenant,  and without  obtaining its or their consent thereto
and any such actions shall not relieve Tenant of liability, under this Lease.

11.5  Administrative  and  Attorneys'  Fees.  If Tenant  effects a  transfer  as
provided  for under  Section 11.6 herein or Landlord  consents to any  transfer,
then Tenant shall,  upon demand,  pay Landlord a non- refundable  administrative
fee of Five Hundred Dollars  ($500.00),  plus any  consultants',  engineers' and
reasonable  attorneys'  fees,  not to exceed  Five  Hundred  Dollars  ($500.00),
incurred  by Landlord in  connection  with such  transfer or request for consent
(whether   attributable  to  Landlord's  in-house  attorneys  or  paralegals  or
otherwise).  Acceptance of the $500.00  administrative  fee and reimbursement of
Landlord's  attorneys' and paralegal fees shall in no event obligate Landlord to
consent to any proposed transfer.

11.6  Assignment  or sublease  with an  Affiliate.  Tenant,  without  Landlord's
consent,  may enter into a transfer  with an  "Affiliate"  (as  defined  below);
provided that (i) Tenant remains  liable under this Lease,  and (ii) the parties
execute an assignment  of lease on a form  approved by Landlord.  In this Lease,
the term  "Affiliate"  means an  entity  at least  50% of which is under  common
ownership or control with Tenant.

12.1  Landlord's  Obligation.  Landlord  shall  not be  responsible  to make any
repairs,  renovations  or  maintenance  to any part of the  Premises  except  as
expressly  provided  herein.  Except for repairs that Tenant is required to make

and working order the Building and roof area (excluding Tenant's Property),  (b)
make all repairs and  replacement  to all  exterior  structural  portions of the
Building,  including, but not limited to, the exterior Building walls (including
doors), roof and foundations,  adjoining sidewalks, driveways, service areas and
curbs  (irrespective of any duty on the part of any governmental  agency to make
or order such  repairs  and  replacements),  and all  repairs  and  replacements
necessary  to put and  maintain  the  exterior of the  Building and parking area
(including,  but not limited to,  filling holes and resealing as necessary,  but
subject to normal wear and tear),  including all  improvements  now or hereafter
thereon,  and all appurtenances  thereto (including sewer and sewer connections,
water and gas pipes and connections, electrical wires and connections) in a safe
and tenantable condition and in good order and repair,  except for those repairs
made  necessary by the negligent acts or default of the Tenant or its employees,
and (c) provide for lawn,  landscaping and shrubbery care and snow removal.  The
cost of all of the  foregoing  shall be included in the  Operating  Expenses and
paid by Tenant on a pro rata  basis as and to the extent  provided  in Article 7
herein.  Tenant shall  immediately give Landlord written notice of any defect or
need for repairs of which the Tenant becomes aware. After such notice,  Landlord
shall have a reasonable  opportunity  to repair or cure such defect.  Landlord's
liability with respect to any defects, repairs or maintenance for which Landlord
is responsible under any of the provisions of this Lease shall be limited to the
cost of such repairs or  maintenance  or the curing of such  defect.  Landlord's
liability with respect to any defects, repairs or maintenance for which Landlord
is responsible under any of the provisions of this Lease shall be limited to the
cost of such repairs or maintenance or the curing of such defect.

12.2 Tenant's Obligation.  Tenant shall, at its own expense,  maintain all parts
of the Premises and Tenant's Property (except those for which Landlord is either
expressly responsible or elects to undertake pursuant to Article 12.1 or 12.3 of
this  Lease) in good  condition,  promptly  making all  necessary,  repairs  and
replacements,  including  interior,  windows,  glass  and  plate  glass,  doors,
interior  walls and  finish  work,  floors  and  floor  covering,  lighting  and
electrical  systems,  and HVAC and mechanical  systems  (including  fixtures and
equipment).  Tenant,  at its expense,  shall install and maintain any additional
fire  extinguishers  and other fire  protection  devices as may be required from
time to time by any Legal Requirement or agency having  jurisdiction over, or by
the underwriters  issuing  insurance for, the Building.  During the Term of this
Lease and any extension thereof,  Tenant shall provide, at its expense,  proper,
periodic  and  normal  maintenance  and  inspection  for  such  heating  and air
conditioning  equipment as exists upon the Premises at the Commencement Date. If
such equipment  requires repairs or replacement of parts, or both, of a major or

<PAGE>

substantial  nature (i.e., in excess of proper,  periodic and normal maintenance
and  inspection),  such  repairs  or  replacements,  or  both,  shall be made by
Landlord at its expense (such  expense to be included in Operating  Expenses and
paid for by Tenant on a pro rata basis as provided in Article 7 hereof),  unless
Tenant's  misuse or abuse of same  necessitates  the repair or  replacement,  or
both.  Examples of "parts of a major or  substantial  nature"  are  compressors,
boilers  and fan  units.  If any  heating  and  air  conditioning  equipment  is
installed  as part of the  Tenant  Improvements,  Landlord  shall (to the extent
transferable) transfer to Tenant all warranties received from the manufacturers,
dealers  and/or  installers  of such  heating  and air  conditioning  and  other
mechanical  equipment,  and agrees to assist Tenant, to a reasonable  degree, in
enforcing  any such  warranty,  except  enforcement  shall be at  Tenant's  sole
expense.

12.3  Landlord's  Right to Pay,  Maintain  or Repair.  If,  within ten (10) days
following  receipt of written  notice to Tenant,  Tenant fails to pay any amount
Tenant has agreed to pay hereunder or fails to commence to repair or replace any
item which is Tenant's  obligation  to perform,  and  diligently  pursue  timely
completion of such repair and  replacement,  Landlord may. at its option,  cause
all such payments,  required  maintenance,  repairs or  replacements to be made.
Tenant shall pay Landlord all costs incurred in connection  therewith (including
reasonable  attorneys' fees and costs of collection,  if any) within thirty (30)
days of the receipt by the Tenant of an invoice from  Landlord.  Interest  shall
accrue  thereon at the Interest  Rate if not paid within said 30-day period from
the due date until paid.

                        INITIAL CONSTRUCTION; ALTERATIONS

13.1 Initial  Construction.  Landlord and Tenant agree that the  construction of
the Landlord  Work and other initial  construction  with respect to the Premises
shall be  performed  in  accordance  with  Exhibit B (Work  Agreement)  attached
hereto.

13.2 Alterations. Except with regard to decorative or non-structural Alterations
which  do not  exceed  One  Dollar  ($1.00)  per  rentable  square  foot  in the
aggregate,  Tenant  shall not make or permit any  Alterations  without the prior
written consent of Landlord which consent shall not be unreasonably  withheld or
delayed. Landlord may impose any reasonable conditions to its consent, including
(i) delivery to Landlord of written and unconditional  waivers of mechanic's and
materialmen's liens as to the Premises,  the Building,  the Complex and the Land
for all work,  labor and services to be performed and materials to be furnished,
signed   by  all   contractors,   subcontractors,   materialmen   and   laborers
participating  in  the  Alterations,  (ii)  prior  approval  of  the  plans  and
specifications and Tenant's contractor(s) with respect to the Alterations, (iii)
supervision  by  Landlord's   representative   at  Landlord's   expense  of  the
Alterations  and (iv)  delivery to Landlord  of payment  and  performance  bonds
naming Landlord and Mortgagee as obligees.  The Alterations shall conform to the
requirements of Landlord's and Tenant's  insurers and of any Legal  Requirements
applicable to the Premises,  shall be performed in accordance with the terms and
provisions  of this Lease in a good and  workmanlike  manner  befitting  a first
class  office/industrial  building  and shall not  adversely  affect  the value,
utility or character of the Premises.  If the  Alterations  are not performed as
herein required,  Landlord shall have the right, at Landlord's  option,  to halt
any further  Alterations,  or to require  Tenant to perform the  Alterations  as
herein  required or to require  Tenant to return the  Premises to its  condition
before such  Alterations.  Notwithstanding  the foregoing,  if any mechanic's or
materialmen's  lien is filed against the Premises,  the Building or the Land for
work claimed to have been done for, or materials  claimed to have been furnished

<PAGE>

to or for the benefit of,  Tenant,  such lien shall be  discharged  of record by
Tenant within ten (10) business days by the payment thereof or the filing of any
bond required by law. If Tenant shall fail to discharge any such lien,  Landlord
may (but shall not be obligated to) discharge the same,  the cost of which shall
be paid by  Tenant  within  three  (3)  business  days of  receipt  of demand by
Landlord. Such discharge by Landlord shall not be deemed to waive or release the
default of Tenant in not discharging the same. Neither Landlord's consent to the
Alterations  nor  anything  contained  in this  Lease  shall be deemed to be the
agreement or consent of Landlord to subject Landlord's interest in the Premises,
the Building,  the Complex or the Land to any mechanic's or materialmen's  liens
which may be filed in respect of the Alterations.

13.3 Removal of  Alterations.  Except to the extent Tenant requests and Landlord
designates otherwise at the time Landlord approves such Alterations,  all or any
part  of the  Alterations  made  after  the  Commencement  Date  of  this  Lease
(including  wall-to-wall  carpet),  whether  made with or without the consent of
Landlord, shall, at the election of Landlord, either be removed by Tenant at its
expense  before the expiration of the Term or shall remain upon the Premises and
be surrendered  therewith at the Expiration Date or earlier  termination of this
Lease as the property of Landlord  without  disturbance,  molestation or injury.
Notwithstanding  the previous  sentence,  Tenant shall in all cases,  remove all
Cabling installed at any time during the Lease Term and any applicable extension
or  renewal  term.  If  Landlord  requires  the  removal  of all or  part of the
Alterations,  Tenant, at its expense, shall repair any damage to the Premises or
the Building  caused by such removal.  If Tenant fails to remove the Alterations
upon  Landlord's  request,  then  Landlord may (but shall not be  obligated  to)
remove the same and the cost of such removal and repair of any damage  caused by
the same,  together  with any and all  damages  which  Landlord  may  suffer and
sustain by reason of the failure of Tenant to remove the same,  shall be charged
to Tenant and paid upon demand.

13.4 Landlord Alterations. Subject to Article 12.1, 13.1 and Exhibit B, Landlord
shall have no obligation to make any  Alterations in or to the Premises.  Except
as  expressly  provided  in the  preceding  sentence,  Tenant  shall  accept the
Premises in its "AS-IS" condition.

advertisement  or  notice  shall  be  inscribed,  painted,  affixed,  placed  or
otherwise  displayed by Tenant or such  subtenant on any part of the Land or the
outside or the inside  (including  windows) of the Complex,  the Building or the
Premises without the Landlord's prior written approval, which approval shall not
be  unreasonably  withheld,  conditioned  or delayed.  If any  prohibited  sign,
advertisement or notice is nevertheless exhibited by Tenant, Landlord shall have
the right to remove the same, and Tenant shall pay any and all expenses incurred
by Landlord in such  removal,  together  with  interest  thereon at the Interest

<PAGE>

Rate. as Additional  Rent.  Landlord  shall have the right to prohibit any sign,
advertisement,  notice or  statement  to the  public  by  Tenant  in  Landlord's
reasonable discretion.

14.2 Exterior Sign. Subject to all Legal Requirements,  Tenant, at its cost, may
install  a sign  with its name and logo  ("Tenant's  Exterior  Sign") on the top
signage band of the Building facing Lafayette Center Drive. The design, size and
location of Tenant's  Exterior Sign shall be approved by Landlord.  Tenant shall
maintain Tenant's Exterior Sign in good condition at all times,  shall remove it
at the end of the Term,  and shall  repair  any damage  caused by this  removal.
Tenant shall comply with all Legal Requirements  pertaining to Tenant's Exterior
Sign.

operate  in the  Premises  (i) any  electrically  operated  equipment  or  other
machinery,  other than normal and customary equipment  reasonably  necessary for
Tenant's Permitted Use of the Premises and that does not require wiring, cooling
or other service in excess of existing Building  systems,  (ii) any equipment of
any kind or nature  whatsoever  which will require any changes,  replacements or
additions  to, or  changes  in the use of, any  water,  heating,  plumbing,  air
conditioning or electrical system of the Premises or the Building,  or (iii) any
equipment  which causes the floor load to exceed the load limits set by Landlord
for the Building. Machines and equipment which cause noise or vibration that may
be transmitted to the structure of the Building or to any space therein so as to
be objectionable to Landlord shall be installed and maintained by Tenant, at its
expense, on vibration  eliminators or other devices sufficient to eliminate such
noise and vibration.

16.1 General.  Tenant shall permit Landlord or its Agents, with reasonable prior
notice,  during normal  business hours and  accompanied by a  representative  of
Tenant  (except  in the case of an  emergency),  to enter  the  Premises  (i) to
examine,  inspect and protect the Premises,  (ii) to make such  alterations  and
repairs or perform such  maintenance  which in the sole judgment of Landlord may
be deemed  necessary  or  desirable,  or (iii) to exhibit the same to present or
future Mortgagee; provided that all such non-emergency access by Landlord or its
agents  shall be subject  to all  governmental  laws,  rules,  regulations,  and
requirements regarding secret,  confidential,  or other sensitive items, work or
material;  provided,  further,  in the event the nature of  Tenant's  work in or
about the Premises  precludes any access by Landlord to a particular area of the
Premises at any given inspection time, Landlord and Tenant agree to cooperate in
mutual good faith to arrange an alternative  inspection  arrangement or time. In
exercising its rights pursuant to this Section or during any other access to the
Premises,  Landlord  shall use  reasonable  efforts to  minimize  disruption  or

<PAGE>

inconvenience  to Tenant in connection  with  Landlord's  entry to the Premises.
Notwithstanding anything herein to the contrary, if Tenant shall fail to provide
Landlord  with means  for,  or  otherwise  take any  action  that would  prevent
Landlord from,  obtaining emergency access to the Premises  (including,  without
limitation,  placing  additional  locks or bolts of any kind  upon any  doors or
windows, changing existing locks or the mechanism thereof, or failure to key all
locks to a master  key and to deliver a copy of said  master  key to  Landlord),
Landlord may obtain such emergency access by forcible entry,  without  liability

deprivation  by any third party,  provided that Landlord shall have no liability
to Tenant, nor shall Tenant have any right to abatement or rent or other remedy,
by reason of such third  party  acts.  Additionally,  The  Landlord  shall grant
Tenant  access  to the  telephone  rooms  and  electric  rooms  of the  Building

any equipment or material, in or about the Premises,  the Building,  the Complex
or the Common Area which will  increase  the rate of fire or other  insurance on

stated by any insurance company or by the applicable  insurance rating bureau to
be due to any  activity,  equipment  or  material  of  Tenant  in or  about  the
Premises,  the Building, the Complex or the Common Area, such statement shall be
conclusive  evidence that the increase in such rate is due to the same and, as a
result thereof,  Tenant shall pay such increase to Landlord upon demand but only
for so long as the acts or omissions of Tenant is the basis for such increase.

17.2 Liability  Insurance.  Tenant shall, at its sole cost and expense,  procure
and maintain  throughout the Term a commercial general liability policy insuring

Premises;  (ii) the condition of the Premises;  (iii)  Tenant's  operations  in,
maintenance and use of the Premises, Building and Common Area, and (iv) Tenant's

event  less than One  Million  Dollars  ($1,000,000.00)  per  occurrence,  on an
occurrence basis, and shall be primary over any insurance carried by Landlord.
Endorsements shall be obtained for cross-liability and contractual liability.
<PAGE>

17.3  Insurance  for  Tenant's  Property.  Tenant  shall,  at its sole  cost and
expense,  procure and maintain  throughout the Term a property  insurance policy
(written on an "All Risk" basis) insuring all of Tenant's Property, for not less
than the full replacement cost of said property.  All proceeds of such insurance
shall  be used to  repair  or  replace  Tenant's  Property.  If  this  Lease  is

time upon the reasonable request of the Landlord or its Mortgagee.

      (b) Tenant shall,  at all times during the term hereof, maintain in effect
workers' compensation insurance as required by applicable Legal Requirements.

17.5  Requirements  of Insurance  Coverage.  All such  insurance  required to be
carried by Tenant  herein  shall be with an  insurance  company  licensed  to do
business in the  Commonwealth  of Virginia and rated not lower than A-XII in the
A.M. Best Rating Guide.  Such  insurance (i) shall contain an  endorsement  that
such  policy  shall  remain in full  force and effect  notwithstanding  that the
insured has released its right of action against any party before the occurrence
of a loss;  (ii) shall name  Landlord as an  additional  insured  party and loss
payee; and (iii) shall provide that the policy shall not be canceled,  failed to
be renewed  or  materially  amended  without at least  thirty  (30) days'  prior
written notice to Landlord and, at Landlord's reasonable request, any Mortgagee.
On or before the Commencement  Date and,  thereafter,  not less than thirty (30)
days before the  expiration  date of the  insurance  policy,  an original of the
policy  (including  any  renewal  or  replacement  policy) or a  certified  copy
thereof.,  together with evidence satisfactory to Landlord of the payment of all
premiums for such policy, shall be delivered to Landlord. Any insurance required
by the terms of this Lease to be carried by Tenant may be under a blanket policy
(or policies)  covering  other leases of Tenant and/or its related or affiliated
corporations.  If such insurance is maintained  under a blanket  policy,  Tenant
shall  procure and  deliver to Landlord a statement  from the insurer or general
agent of the  insurer  setting  forth the  coverage  maintained  and the amounts
thereof allocated to the risks intended to be insured hereunder.

from  liability,  for any loss or damage to any building,  structure or tangible
personal  property,,  or any resulting loss of income,  or losses under worker's
compensation  laws and  benefits,  notwithstanding  that  such  loss,  damage or
liability  may arise  out of the  negligent  or  intentionally  tortious  act or
omission of the other party or its Agents,  if such loss or damage is covered by

<PAGE>

insurance benefiting the party, suffering such loss or damage or was required to
be covered by  insurance  pursuant to this Lease.  Each party,  hereto shall use
reasonable  efforts to have a waiver of subrogation  clause (providing that such
waiver of right of  recovery,  against  the other  party  shall not  impair  the
effectiveness of such policy or the insured's  ability,  to recover  thereunder)
included in its said policies, and shall promptly notify the other in writing if
such clause cannot be included in any such policy; if such waiver of subrogation
clause shall not be available,  then the  foregoing  waiver of right of recovery
shall be void.

17.7  Security . Tenant  shall enter into a contract to maintain  the  security,
system for the Premises.  Such  engagement  shall in no way increase  Landlord's
liability,  for occurrences and/or  consequences which such a system is designed
to detect or avert and Tenant  shall look solely to its insurer as set out above
for claims for damages or injury to any person or property.

17.8 Landlord's Insurance.  Beginning on the date of this Lease and at all times
thereafter during the term of this Lease, Landlord shall maintain:

      (a) standard  all-risk fire (boiler and  machinery  coverage) and casualty
insurance,  covering the  Building in amounts at least equal to the  replacement
cost of the  Building  at the time in  question,  but in no event less than such
coverage as is required to avoid coinsurance provisions;

      (b)  commercial liability  insurance with minimum limits of $5,000,000 for
injury to or death of one or more persons in any one  occurrence  and for damage
to or destruction of property in any one occurrence;

      (c) employer's liability insurance for bodily injury;

      (d) excess liability insurance;

      (e) worker's compensation insurance in statutory limits; and

      (f) such other insurance coverage as is customarily  carried in respect of
Comparable Buildings.

The limits shall be  increased by Landlord  from time to time during the term of
this Lease to at least such minimum limits as shall then be customary in respect
of  Comparable  Buildings.  All  policies of  insurance  required  hereby  shall
provide, to the extent available, that they will not be cancelled upon less than
thirty  (30) days'  prior  notice to Tenant.  Landlord  shall  furnish  Tenant a
certificate or certificate of insurance  certifying that the insurance  coverage
required hereby is in force.  Any insurance  required by the terms of this Lease
to be carried by Landlord may be under a blanket  policy (or policies)  covering
other properties of Landlord and/or its related or affiliated  corporations.  If
such insurance is maintained under a blanket policy,  Landlord shall procure and
deliver to Tenant a statement  from the insurer or general  agent of the insurer
setting forth the coverage  maintained and the amounts thereof  allocated to the
risks intended to be insured hereunder.

                         LANDLORD SERVICES AND UTILITIES

18.1 Ordinary  Services to the Premises.  As long as no Event of Default  beyond
any applicable notice and cure period has occurred and is continuing and subject
to Legal  Requirements  and Force Majeure events,  Landlord shall furnish to the
Premises  throughout the Term (i) electricity  appropriate for the Permitted Use
(but not less  than  six (6)  watts of  electrical  energy  per  square  foot of
rentable  area,  connected  load,  to  the  Premises),   (ii)  heating  and  air
conditioning  appropriate  for the  Permitted  Use  during the  following  hours
(collectively,  the "Building  Hours"):  8:00 a.m. to 6:00 p.m.,  Monday through
Friday,  and 8:00 a.m. to 1:00 p.m. on Saturday,  exclusive  of Holidays,  (iii)
janitorial  service  (including  regular  trash removal from the  Premises),  in
accordance with the cleaning  specifications  attached hereto as Exhibit G, (iv)
hot and cold water from points of supply,  (v) adequate  supplies for  restrooms
located in the Common Area, (vi) elevator service,  provided that, as long as at
least one (1) elevator is in service at all times, Landlord shall have the right
to remove such elevators from service as may be required for moving,  freight or
for  maintaining  the elevators or the Building or for security  reasons,  (vii)
replacement  of building  standard  light bulbs,  (viii) a  reasonable  security
system for the Building  (which,  as of the date hereof,  requires use of access
cards to enter the Building during non-Building Hours), and (ix) maintenance and
repair of HVAC  systems.  As long as no Event of Default  beyond any  applicable
notice and cure  period has  occurred  and is  continuing  and  subject to Legal
Requirements and Force Majeure events,  Tenant shall have access to the Premises
seven (7) days per week,  twenty-four (24) hours per day, every day of the year.
The cost of all services provided by Landlord hereunder shall be included within
Operating  Expenses,  unless  charged  directly  (and  not as part of  Operating
Expenses) to Tenant or another  tenant of the Building.  The foregoing  services
shall be  furnished by Landlord  and  reimbursed  by Tenant as part of Operating
Expenses;  provided,  however, that Landlord shall be under no responsibility or
liability for failure,  defect or  interruption in such services caused by Force
Majeure, breakage,  accident,  strikes, repairs or for any other cause or causes
beyond  the  control  of  Landlord,  nor  in  any  event  for  any  indirect  or
consequential  damages;  and  failure or  omission  on the part of  Landlord  to
furnish such service  shall not be construed as an eviction of Tenant,  nor work
an abatement of Rent, nor render Landlord liable in damages,  nor release Tenant
from prompt  fulfillment of any of the covenants under this Lease.  Landlord may
comply with voluntary controls or guidelines  promulgated  pursuant to any Legal
Requirements  relating to the use or conservation of energy,  water, gas, light,
or  electricity  or the  reduction  of  automobile  or other  emissions  without
creating any  liability of Landlord to Tenant under this Lease.  Landlord  shall
not be  responsible  if the normal  operation of the  Building  air-conditioning
system shall fail to provide  conditioned  air within  comfortable  temperatures
levels (A) in any  portions of the  Premises  which have a connected  electrical
load for all  purposes  (including  lighting  and  power) or which  have a human
occupancy in excess of the average  electrical load and human occupancy  factors
for which the  Building  air-conditioning  system is  designed,  (B)  because of
Alterations made by or on behalf of Tenant,  (C) in any portions of the Premises
exposed to direct  sunlight in which Tenant fails to keep the window  treatments
closed,  or (D)  because of the  failure by Tenant or its Agents to use the HVAC
system  in the  manner in which it was  designed  to be used.  Tenant  agrees to
observe and comply with all  reasonable  rules from time to time  prescribed  by
Landlord for the proper  functioning  and  protection of the HVAC systems in the

<PAGE>

Building. Except in the case of an emergency, Landlord will give Tenant at least
two (2) days prior notice if Landlord intends to interrupt any services required
to be furnished by Landlord.

18.2 After-Hours  Services to the Premises.  If Tenant requires or requests that
the services to be furnished by Landlord (except building  standard  electricity
and  elevator  service) be provided  during  periods in addition to the Building
Hours, then Tenant shall obtain Landlord's  consent thereto and, if such consent
is  granted,  shall  pay  as  Additional  Rent  Landlord's  additional  expenses
resulting therefrom.  Landlord may, from time to time during the Term, set a per
hour charge for  after-hours  service  (which  hourly charge on the date of this
Lease is $35 per hour) which shall include the cost of utility,  service,  labor
costs, administrative costs and a cost for depreciation of the equipment used to
provide such after-hours service.

18.3 Excess Utility Charges. If Tenant's  consumption of electricity exceeds six
(6) watts of electrical energy per square foot of rentable area, connected load,
or if Tenant's electrical consumption consistently occurs beyond Building Hours,
Landlord, in its reasonable discretion,  acting in good faith, may (i) install a
separate  electric  meter or submeter for the Premises at Tenant's cost, or (ii)
bill Tenant for any usage of electric power (a) consistently  occurring  outside
of Building  Hours,  or (b) that exceeds six (6) watts of electrical  energy per
square foot of rentable area,  connected load, at the same cost paid by Landlord
for power usage. In addition,  Landlord shall, upon Tenant's written request and
at  Tenant's  expense,  install a separate  submeter  for the  Premises to meter
Tenant's after-hours electrical consumption (including HVAC, heating and lights)
outside of Building Hours. If Landlord installs a meter for the Premises, Tenant
shall then pay the cost of  electricity  it consumes  directly  to the  electric
company,  and  Landlord  shall  make an  appropriate  good faith  adjustment  to
Tenant's  Proportionate  Share of Operating  Expenses to reflect  such  separate
metering.  If  Landlord  elects to  install  and  installs  a  submeter  for the
Premises,  Tenant  shall be billed  periodically  by  Landlord  based  upon such
consumption,  and Landlord  shall make an appropriate  good faith  adjustment to
Tenant's  Proportionate Share of Operating Expenses to reflect such submetering.
If Landlord  installs a submeter for the  Premises at Tenant's  request to meter
Tenant's  electrical  consumption  outside of Building  Hours,  Tenant  shall be
billed  periodically by Landlord based upon such  consumption.  Tenant shall pay
each invoice that it receives from Landlord under this subarticle within 10 days
after receipt.

18.4 Year 2000  Compliance.  Landlord  warrants  to Tenant  that the  Building's
customary  systems and services are designed to be operational  during and after
the calendar year 2000, and that the Building's  customary  systems and services
will  operate  during those time periods  without any  interruption  of critical
services relating to year 2000 incompatibility.  Notwithstanding anything to the
contrary in this Lease,  if (i) Landlord  breaches the foregoing  warranty,  and
(ii) as a result of this breach,  services to the Premises are  interrupted  and
Tenant is unable to use the  Premises in whole or in part for more than five (5)
continuous days,  then,  starting with the sixth (6thh) day and continuing until
Tenant is again able to use the Premises,  Monthly Base Rent and Additional Rent
shall be  proportionately  abated to the extent that the Premises are  unusable.
Any additional  remedies against Landlord for Landlord's  breach of the warranty
provided in this Article 18.4 shall be limited to those  provided  under Article
22.6 hereof.

                             LIABILITY OF LANDLORD

19.1  No  Liability.  Except  where  due to  Landlord's  negligence  or  willful
misconduct  provable  by Tenant,  Landlord  shall not be liable to Tenant or its
Agents for, and Tenant, for itself and its Agents,  does hereby release Landlord
and its Agents from  liability,  for, any damage,  compensation or claim arising
from (i) the  necessity  of  repairing  any  portion of the  Premises,  (ii) any
interruption  in the use of the  Premises  or the  Common  Area  for any  reason
including any interruption or suspension of utility service, (iii) fire or other
casualty or personal or property  injury,  damage or loss resulting from the use
or  operation  (by  Landlord,  Tenant,  or any other person  whomsoever)  of the
Premises, (iv) the termination of this Lease, (v) robbery,  assault or theft, or
(vi)  any  leakage  in the  Premises  from  water,  rain,  snow or  other  cause
whatsoever.  No such  occurrence  shall give rise to  diminution or abatement of
Rent  or  constructive  eviction.  Notwithstanding  the  foregoing,  any  goods,
automobiles,  property  or  personal  effects  stored or placed by Tenant or its
Agents in or about the  Premises,  shall be at the sole risk of  Tenant;  Tenant
hereby  expressly  waives its right to recover  against  Landlord and its Agents
therefor.  Tenant hereby waives any claim it might have against  Landlord or its
Agents for any  consequential  damages or business  losses  sustained  by Tenant
arising out of the loss or damage to any person or  property  of Tenant,  or any
interruption in the use of the Premises, for any reason. Tenant acknowledges its
obligation to insure against such losses and damages.

19.2 Indemnity.  Tenant shall indemnify,  defend,  protect and hold Landlord and
its Agents harmless from and against any and all damage, claim, liability,  cost
or expense (including attorneys' or other professionals' fees) of every kind and
nature  (including  those  arising  from any  injury or  damage  to any  person,
property or  business)  incurred by or claimed  against  Landlord or its Agents,
directly or indirectly,  as a result of, arising from or in connection  with (i)
Tenant's or its Agents' use and occupancy of the Premises;  (ii) Tenant's breach
of this Lease; or (iii) any act, omission or negligence of Tenant or its Agents;
provided that Tenant shall not be required to indemnify Landlord for any damage,
injury, loss or expense arising as a result of act(s), omission(s) or negligence
of Landlord or its Agents.  Tenant's  obligation  to indemnify and hold Landlord
harmless  shall be  limited  to the sum that  exceeds  the  amount of  insurance
proceeds, if any, received by the Landlord.

19.3 Limitation on Recourse. Notwithstanding anything contained in this Lease to
the contrary, the obligations of Landlord under this Lease (including any actual
or alleged breach or default by Landlord) do not constitute personal obligations
of  the  individual  partners,  directors,  officers,  shareholders,   trustees,
advisors or agents of Landlord or Landlord's partners, and Tenant shall not seek
recourse against the individual partners,  directors,  officers or shareholders,
trustees, advisors or agents of Landlord or Landlord's partners, or any of their
personal assets for satisfaction of any liability with respect to this Lease. In
addition,  in  consideration  of the benefits  accruing  hereunder to Tenant and
notwithstanding anything contained in this Lease to the contrary,  Tenant hereby
covenants and agrees for itself and all of its  successors  and assigns that the
liability  of  Landlord  for its  obligations  under this Lease  (including  any
liability  as a result  of any  actual or  alleged  failure,  breach or  default
hereunder  by  Landlord),  shall be  limited  solely to,  and  Tenant's  and its
successors' and assigns' sole and exclusive  remedy shall be against  Landlord's
interest  in  the  Building,   the  Complex  and  Land  and/or  such  respective

<PAGE>

partnership  interests or assets and proceeds therefrom,  and no other assets of
Landlord.  In the event that the original Landlord  hereunder,  or any successor
owner of the Building,  shall sell or convey the Building,  all  liabilities and
obligations on the part of the original Landlord, or such successor owner, under
this Lease occurring  thereafter shall terminate as of the day of such sale, and
thereupon  all such  liabilities  and  obligations  shall be  binding on the new
owner.

                             RULES AND REGULATIONS

20.1 General.  Tenant and its Agents shall at all times abide by and observe the
Rules  and  Regulations  and  any  amendments  thereto  that  may be  reasonably
promulgated  from time to time by Landlord for the operation and  maintenance of
the  Building,  the Complex  and the Common  Area and the Rules and  Regulations
shall be deemed to be covenants of the Lease to be performed  and/or observed by
Tenant.  Nothing  contained  in this Lease  shall be  construed  to impose  upon
Landlord any duty or  obligation  to enforce the Rules and  Regulations,  or the
terms or  provisions  contained in any other lease,  against any other tenant of
the Building or the Complex; provided,  however, that Landlord shall enforce the
Rules and  Regulations  in a  nondiscriminatory  manner.  Landlord  shall not be
liable to Tenant for any violation by any party of the Rules and  Regulations or
the terms of any  other  Building  lease.  Landlord  shall (a) not  unreasonably
withhold,  condition or delay its consent from Tenant for any approval  required
under the Rules and Regulations; and (b) exercise its judgement in good faith in
any  instance  providing  for the  exercise  of its  judgement  in the Rules and
Regulations.  Landlord  shall  use  commercially  reasonable  efforts  to secure
compliance by all tenants and other  occupants  with the Rules and  Regulations,
provided  that (i)  Landlord  shall  have no  liability  to  Tenant by reason of
non-compliance  by other tenant or other  occupant and (ii)  Landlord may permit
reasonable  waivers with respect to other parties so long as such waivers do not
materially and  unreasonably  adversely  affect Tenant's use or occupancy of the
Premises.  If there is any  inconsistency  between  this Lease and the Rules and
Regulations,  this Lease shall govern.  Landlord reserves the right to amend and
modify the Rules and Regulations as it deems necessary, provided such changes do
not materially  and  unreasonably  adversely  affect  Tenant's  normal course of
business or increase  Tenant's  costs.  The current  Rules and  Regulations  are
attached hereto as Exhibit D and made a part hereof.

                            DAMAGE AND CONDEMNATION

21.1 Minor  Destruction  of Premises.  In the event of damage to the Premises by
fire or any other cause which  renders fifty percent (50%) or less of the entire
area of the Premises  untenantable,  then  provided that such damage was not the
consequence  of the fault or negligence  of Tenant or its Agents,  the Base Rent
and Tenant's  Proportionate share shall be reduced,  for the period beginning on
the date of such damage and ending on the date that such damage  shall have been
repaired,  by the ratio that the rentable square footage of the Premises that is
rendered  so  untenantable  and is  unoccupied  by  Tenant  bears to the  entire
rentable square footage of the Premises before such damage.
<PAGE>

21.2  Substantial  Destruction  of  Premises.  In  the  event  of  damage  to or
destruction  of the  Premises by fire or any other cause which  renders the more
than fifty  percent (50%) of the entire area of the Premises  untenantable,  the
Rent shall wholly abate and be apportioned from the date the damage occurs until
the damage shall have been repaired.

21.3 Time For Repairs.  In the event of any damage or  destruction  described in
Section 21.2 hereof,  unless this Lease is terminated as hereinafter provided in
Section 21.5 or Section 21.6 hereof, as soon as practicable (taking into account
the time  necessary  to  effect a  satisfactory  settlement  with any  insurance
company  involved and any delays  beyond the direct  control of Landlord)  after
receipt of Tenant's notice to renew this Lease delivered under and in accordance
with Section 28.1 hereof (if such notice is given),  Landlord  shall commence to
repair and restore the Premises to the condition in which they were  immediately
prior to such damage, and Landlord shall substantially  complete such repair and
restoration with such due diligence and dispatch.  If the damage is not repaired
and restored  within a reasonable  time or in any event within two hundred (200)
days after the date the damage  occurs (such two hundred  (200) day period to be
extended by the period of any delay outside the direct  control of Landlord plus
a reasonable  period for a satisfactory  settlement  with any insurance  company
involved),  Tenant,  within  thirty  (30) days from the  expiration  of such two
hundred (200) day period (as the same may be extended), may terminate this Lease
by written notice to Landlord. Substantial completion of such repairs (exclusive
of punchlist items) shall be evidenced by a certificate of Landlord's architect,
which certificate shall include a list of punchlist items to be completed before
final completion.  All rent abatement and apportionment  shall cease on the date
such  certificate is delivered.  Punchlist items  specified in such  architect's
certificate be completed as soon as practicable. The Tenant shall have seven (7)
days after receipt of the  architect's  certificate  to inspect the premises and
notify the Landlord in writing as to any additional  punchlist  items not listed
in architect's  certificate and Landlord shall have thirty (30) days in which to
have such items which constitute defects completed.

21.4 General  Provisions  Regarding  Repairs.  Notwithstanding  anything in this
Lease to the contrary,  (a) in making any repairs  contemplated  by this Article
21,  (i)  Landlord's  obligation  to repair  such  damage  shall not  exceed the
proceeds of insurance  available to Landlord  (reduced by any proceeds  retained
pursuant to the rights of Mortgagee), and (ii) Landlord shall not be required to
rebuild,  replace or repair of the  Tenant's  Property,  and (b) Tenant shall be
required to repair or replace the Tenant's Property.

21.5 Right Of Termination.

      (a) In the event the Premises  are  damaged  to the  extent  described  in
Section  21.2  hereof at any time  during the eighth  (8th) Lease Year or at any
time  thereafter  during  the  initial  Term of this  Lease by fire or any other
cause,  then subject to paragraph (b) below, this Lease may be terminated at the
election  of either  Landlord  or Tenant by  giving  notice in  writing  of such
election  to the other party  within  thirty (30) days after the date the damage
occurs.  Upon such  termination,  any unearned  Rent or other  payments  paid in
advance beyond the date of damage shall immediately be refunded to Tenant.
<PAGE>

      (b) If Landlord elects to terminate this Lease under paragraph (a) of this
Section,  Tenant may by written notice to Landlord  exercise its option to renew
under  Article 28 hereof  within  twenty (20) days after  receipt of  Landlord's
notice of termination, and in such event, Landlord's notice of termination shall
be  void,   and  Landlord   shall  repair  the  Premises  as  herein   provided.
Notwithstanding  the  foregoing,  Landlord  shall have no obligation to commence
such repair unless and until such time as the parties have executed an amendment
to this Lease  establishing  the rent and other terms for the Renewal Period (as
defined  below) as  contemplated  by  Article  28. In the event  that  Tenant so
exercises  such renewal  option but such an amendment is not so executed  within
the time required by Article 28, then Landlord's termination of this Lease shall
be reinstated and,  notwithstanding anything herein to the contrary, there shall
be no rental abatement by reason of such damage.

      (c) In the event the Term of this Lease shall be extended  for the Renewal
Period  pursuant to Article 28 hereof and the Premises are damaged to the extent
described in Section 21.2 hereof at any time during the thirteenth (13th ) Lease
Year or at any time  thereafter  during the  Renewal  Period,  this Lease may be
terminated  at the  election of either  Landlord  or Tenant by giving  notice in
writing of such  election to the other party  within  thirty (30) days after the
date the  damage  occurs.  Upon such  termination,  any  unearned  Rent or other
payments paid in advance beyond the date of damage shall immediately be refunded
to Tenant.

21.6 Total Destruction.  Notwithstanding anything herein to the contrary, in the
event  that the  Building  is  totally  destroyed  or  damaged  by fire or other
casualty,  then  Landlord may terminate  this Lease by written  notice to Tenant
delivered within thirty (30) days after the date of such damage or destruction.

21.7  Condemnation.  If the whole or a  Substantial  Part of the Premises or the
Building shall be taken or condemned by any  governmental or  quasi-governmental
authority for any public or quasi-public  use or purpose  (including sale trader
threat of such a taking), then the Term shall cease and terminate as of the date
when title vests in such governmental or quasi-governmental  authority, and Rent
shall  be  prorated  to the  date  when  title  vests  in such  governmental  or
quasi-governmental  authority.  If (a)  less  than  a  Substantial  Part  of the
Premises  is  taken  or  condemned  by any  governmental  or  quasi-governmental
authority for any public or  quasi-public  use or purpose  (including sale under
threat of such a taking),  or (b) such  condemnation is not extensive  enough to
render the  Premises  unusable  for the  purposes  for which the  premises  were
leased,  and this Lease  shall not be  terminated  under the  provisions  of the
immediately  proceeding  sentence,  then (i) Landlord shall promptly restore the
Premises to a condition  comparable to its condition  immediately  prior to such
condemnation,  less the portion  thereof taken in such  condemnation,  (ii) Base
Rent and  Tenant's  Proportionate  Share  shall be reduced by the ratio that the
portion so taken bears to the rentable  square  footage of the  Premises  before
such taking,  effective as of the date when title vests in such  governmental or
quasi-governmental  authority,  and (iii) this Lease shall otherwise continue in
full  force  and  effect.  Tenant  shall  have no  claim  against  Landlord  (or
otherwise) as a result of such taking, and Tenant hereby agrees to make no claim
against  the  condemning  authority,  for any  portion of the amount that may be
awarded  as  compensation  or  damages  as a result  of such  taking;  provided,
however,  that  Tenant  may,  to the extent  allowed by law,  claim an award for
moving  expenses and for the taking of any of Tenant's  Property (other than its
leasehold  interest  in the  Premises)  which does not,  under the terms of this

<PAGE>

Lease.  become the property of Landlord at the  termination  hereof,  as long as
such claim is separate  and  distinct  from any claim of  Landlord  and does not
diminish  Landlord's  award.  Tenant  hereby  assigns to Landlord  any right and
interest it may have in any award for its leasehold interest in the Premises.

                                   ARTICLE 22
                                    DEFAULT

22.1 Events of  Default.  Each of the  following  shall  constitute  an Event of
Default:  (i) Tenant fails to pay Rent within five (5) days after written notice
from Landlord is received by Tenant; (ii) Tenant fails to observe or perform any
other term,  condition  or covenant  herein  binding upon or  obligating  Tenant
within  thirty  (30) days after  notice  from  Landlord  is  received by Tenant;
provided,  however,  that if such  failure is not able to be cured  within  said
30-day  period,  Tenant shall have a reasonable  period of time not to exceed an
additional ninety (90) days in which to satisfy or cure said breach  conditioned
upon Tenant promptly  commencing to cure such breach and diligently pursuing the
cure to completion,  (iii) Tenant  abandons the Premises  (other than the Sublet
Space);  (iv) Tenant or any Guarantor makes or consents to a general  assignment
for the benefit of  creditors or a common law  composition  of  creditors,  or a
receiver of the Premises or all or substantially  all of Tenant's or Guarantor's
assets is appointed; or (v) a transfer in violation of Article 11 herein.

22.2 Landlord's Remedies. Upon the occurrence of an Event of Default,  Landlord,
at its option,  without  further notice or demand to Tenant,  may in addition to
all other rights and remedies provided in this Lease, at law or in equity:

              (i) Terminate  this Lease and Tenant's  right of possession of the
Premises,  and  recover all  damages to which  Landlord  is entitled  under law,
specifically  including  all of  Landlord's  reasonable  expenses  of  reletting
(including market rental concessions to new tenants, repairs, Alterations, legal
fees and brokerage  commissions).  If Landlord  elects to terminate  this Lease,
every obligation of the parties shall cease as of the date of such  termination,
except that Tenant shall remain  liable for payment of Rent and  performance  of
all other terms and conditions of this Lease to the date of termination.

              (ii)  Terminate  Tenant's  right  of  possession  of the  Premises
without  terminating  this Lease, in which event Landlord shall use commercially
reasonable efforts to relet the Premises,  or any part thereof,  for the account
of  Tenant,  for  such  rent and term and  upon  such  other  conditions  as are
acceptable to Landlord.  For purposes of such reletting,  Landlord is authorized
to redecorate, repair, alter and improve the Premises to the extent commercially
reasonable. Until Landlord relets the Premises, Tenant shall remain obligated to
pay Rent to Landlord as provided  in this Lease.  If and when the  Premises  are
relet and if a sufficient sum is not realized from such reletting  after payment
of all Landlord's reasonable expenses of reletting (including rental concessions
to new tenants, repairs.  Alterations.  legal fees and brokerage commissions) to
satisfy the payment of Rent due under this Lease for any month. Tenant shall pay
Landlord any such deficiency  upon demand.  Tenant agrees that Landlord may file
suit to recover any sums due  Landlord  under this Article from time to time and

<PAGE>

that such suit or recovery of any amount due  Landlord  shall not be any defense
to any  subsequent  action  brought  for any  amount not  previously  reduced to
judgment in favor of Landlord.

              (iii) Terminate this Lease and Tenant's right of possession of the
Premises,  and recover from Tenant the net present  value (using a discount rate
of 6% per  annum)  of the  excess,  if any,  of all  Rent  due  from the date of
termination  until the Expiration  Date over the reasonable  rental value of the
Premises for that period;

              (iv)  Re-enter and  repossess  the Premises and remove all persons
and effects therefrom, by summary, proceeding,  ejectment or other legal action.
Landlord shall have no liability by reason of any such re-entry, repossession or
removal.

              (v) Recover from Tenant, to the extent permitted under the laws of
the  Commonwealth  of  Virginia,  the  value  and/or  cost  of  all  unamortized
concessions to Tenant under this Lease.

22.3  Rights Upon  Possession.  If Landlord  takes  possession  pursuant to this

compromise or settlement  thereof shall be made, the same shall not constitute a
waiver of any other covenant,  condition or agreement herein  contained,  nor of

23.1  Subordination.  This  Lease and  Tenant's  interest  hereunder  shall have
priority over, and be senior to, the lien of any Mortgage made by Landlord after
the date of this Lease.  However, if at any time or from time to time during the
Term, a mortgagee or  prospective  mortgagee  ("Mortgagee")  requests  that this
Lease be subject  and  subordinate  to its  mortgage or deed or trust or similar
lien ("Mortgage"),  and if Landlord consents to such  subordination,  this Lease
and Tenant's interest  hereunder shall be subject and subordinate to the lien of
such Mortgage and to all renewals, modifications,  replacements,  consolidations
and  extensions  thereof and to any and all  advances  made  thereunder  and the
interest  thereon.  Tenant  agrees  that,  within ten (10)  business  days after
receipt of a written request therefor from Landlord, it will, from time to time,
execute and deliver any reasonable  instrument or other document required by any
such Mortgagee to subordinate this Lease and its interest in the Premises to the
lien of such  Mortgage.  If, at any time or from time to time during the Term, a
Mortgagee of a Mortgage  made prior to the date of this Lease shall request that
this  Lease  have  priority  over the  lien of such  Mortgage,  and if  Landlord

and all renewals,  modifications,  replacements,  consolidations  and extensions
thereof and all advances made  thereunder and the interest  thereon,  and Tenant

<PAGE>

shall,  within ten (10) business  days after receipt of a request  therefor from
Landlord, execute,  acknowledge and deliver any and all reasonable documents and
instruments  confirming the priority of this Lease.  In any event,  however,  if
this Lease shall have  priority  over the lien of a first  Mortgage,  this Lease
shall not become subject or subordinate to the lien of any subordinate Mortgage,
and Tenant shall not execute any subordination  documents or instruments for any
subordinate Mortgagee, without the written consent of the first Mortgagee.

              This Lease and Tenant's  interest  hereunder  shall be subject and
subordinate to each and every,  ground or underlying lease hereafter made of the
Building,  the  Complex  or  the  Land,  and  to  all  renewals,  modifications,
consolidations,  replacements and extensions thereof. Tenant agrees that, within
ten (10) business days after receipt of request therefor from Landlord, it will,
from time to time,  execute,  acknowledge  and deliver any  instrument  or other
document  required by any such lessor to subordinate this Lease and its interest
in the Premises to such ground or underlying lease.

23.2  Mortgagee  Protection.  Tenant  agrees to give any  Mortgagee by certified
mail.  return  receipt  requested,  a copy of any notice of default  served upon
Landlord,  provided  that before such notice Tenant has been notified in writing
of the address of such  Mortgagee.  Tenant further agrees that if Landlord shall
have failed to cure such  default  within the time  provided  for in this Lease,
then the Mortgagee  shall have an additional ten (10) business days within which
to  cure  such  default;  provided,  however,  that if such  default  cannot  be
reasonably  cured  within  that  time.  then  such  Mortgagee  shall  have  such
additional  time as may be  necessary  to cure such default so long as Mortgagee
has commenced and is diligently  pursuing the remedies  necessary,  to cure such
default (including the commencement of foreclosure  proceedings,  if necessary),
in which event Tenant  shall not  exercise  any remedies for default  while such
remedies are being so diligently  pursued. In the event of the sale of the Land.
the  Complex  or the  Building,  by  foreclosure  or deed in lieu  thereof,  the
Mortgagee or purchaser at such sale shall be  responsible  for the return of the
Security  Deposit only to the extent that such  Mortgagee or purchaser  actually
received the Security Deposit.

23.3   Modification   Due  to  Financing.   If,  in  connection  with  obtaining
construction or permanent financing for the Premises,  the Building, the Complex
or the Land, any lender (or Mortgagee) shall request reasonable modifications of
this Lease as a condition to such  financing,  Tenant shall  promptly  execute a
modification  of this  Lease,  provided  such  modifications  do not  materially
increase the financial  obligations of Tenant hereunder or materially  adversely
affect the leasehold  interest  hereby  created or Tenant's  reasonable  use and
enjoyment  of the  Premises.  Tenant  and any  Guarantor  shall  each,  prior to
execution and annually' throughout the Term upon request, provide such financial
information  and  documentation  about itself to Landlord or Mortgagee as may be
requested.

Premises, (ii) the termination of any ground or underlying lease of the Complex,
the Building or the Land, or (iii) the purchase of the Complex,  the Building or
Landlord's  interest  therein  in a  foreclosure  sale  or by  deed  in  lieu of

<PAGE>

foreclosure  under any Mortgage or pursuant to a power of sale  contained in any
Mortgage, then in any of such events Tenant shall, at the request of Landlord or
Landlord's  successor in interest,  attorn to and  recognize  the  transferee or
purchaser of Landlord's  interest or the lessor under the  terminated  ground or
underlying  lease,  as the case may be, as  Landlord  under  this  Lease for the
balance then remaining of the Term, and thereafter  this Lease shall continue as
a direct lease between such lessor,  transferee or purchaser, as "Landlord," and
Tenant, as "Tenant," except that such lessor,  transferee or purchaser shall not
be liable for any act or omission of Landlord prior to such lease termination or
prior to its  succession  to title,  nor be  subject to any  offset,  defense or
counterclaim  accruing  prior  to  such  lease  termination  or  prior  to  such
succession to title, nor be bound by any payment of Base Rent or Additional Rent
prior to such lease  termination  or prior to such  succession to title for more
than one month in  advance.  Tenant  shall,  upon  request  by  Landlord  or the
transferee  or  purchaser  of  Landlord's  interest  or  the  lessor  under  the
termination  ground or underlying lease, as the case may be, execute and deliver
an  instrument  or  instruments  confirming  the  foregoing  provisions  of this
Article.  Tenant  hereby  waives the  provisions of any present or future law or
regulation  which gives or purports  to give  Tenant any right to  terminate  or
otherwise  adversely affect this Lease, or the obligations of Tenant  hereunder,
upon or as a result of the termination of any such ground or underlying lease or
the completion of any such foreclosure and sale.

23.5 Non-Disturbance Agreement. Notwithstanding anything to the contrary in this
Article,   Landlord   shall  (i)   obtain  a   subordination,   attornment   and
non-disturbance  agreement (an "SNDA") for the benefit of Tenant from Landlord's
existing  mortgagee,  which shall be executed at the time this Lease is executed
and shall be  substantially  in the form attached  hereto as Exhibit H, and (ii)
use  reasonable  efforts  to obtain a SNDA for the  benefit  of Tenant  from any
future  mortgagees of Landlord (each SNDA from any future  mortgagee shall be on
such mortgagee's standard form).

                                   ARTICLE 28
                                 OPTION TO RENEW

28.1 Exercise of Option.  Tenant shall have the right (the "Renewal  Option") to
extend the Term for one (1) period of five (5) Lease Years (a "Renewal  Period")
provided (i) Tenant gives written notice to Landlord of its election to exercise
its Renewal Option at least 270 days prior to the Expiration  Date,  (ii) Tenant
specifies in such notice all  amendments to the provisions of this Lease for the
Renewal  Period  ("Proposed  Amendments"),  other than the amount of Base Rental
which  shall be  determined  pursuant  to  Sections  28.2  through  28.4  below,
inclusive),  and (iii) no Event of Default exists beyond any  applicable  notice
and cure period at the time Tenant  exercises its Renewal  Option.  Tenant shall
not make any Proposed  Amendments  except those that would conform this Lease to
market based  conditions  then  prevailing for buildings of comparable  type and
quality in the northern  Virginia  metropolitan  area.  Within ten (10) business
days after Landlord's receipt of Tenant's renewal notice,  Landlord shall notify
Tenant of those Proposed Amendments, if any, acceptable to Landlord and of those
Proposed Amendments that Landlord has rejected.  If Landlord shall so reject any
Proposed Amendments, Tenant shall have the right, by written notice delivered to
Landlord  within five (5) business  days after  Tenant's  receipt of  Landlord's

<PAGE>

notice contemplated by the next preceding sentence,  to withdraw its exercise of
the Renewal  Legend.  If Landlord and Tenant shall mutually  agree on which,  if
any, Proposed  Amendments shall be included in this Lease for the Renewal Period
(such Proposed Amendments mutually agreed on are referred to herein as "Approved
Amendments"),  then the parties shall promptly commence to negotiate, and within
30 days  thereafter  reach agreement on, the final form of, an Amendment to this
Lease providing for such Approved Amendments.

28.2 Current Market Rent. Except for Approved Amendments,  if any, all terms and
conditions  of this  Lease  shall  remain in full  force and  effect  during the
Renewal Period, except that (i) annual Base Rent for the first Lease Year of the
Renewal Period and annual  escalations  thereof for each  subsequent  Lease Year
shall be  adjusted  so that  annual  Base Rent for each such Lease  Year  equals
ninety-five  percent (95%) of the "Current Market Rent" (as defined below), (ii)
the Base Year shall be 2010, and (iii) there shall be no further Renewal Option.
The "Current  Market Rent" for purposes of this Lease shall mean the  prevailing
market  rent as of the date such  market  rent is to go into  effect for renewal
leases of other  comparable  office space of the same quality,  size,  location,
level of finish,  and lease term in the Building and in other comparable  office
buildings  located in the northern Virginia  metropolitan  area, for a tenant of
credit-worthiness comparable to that of Tenant, taking into account all relevant
factors,  including the building's age and condition, any significant renovation
of the Building or the leased  space,  all  components of rent,  including  base
rent, the number, type and base year for various rent escalations, base year and
pass-throughs   for  operating   expenses  and  real  estate   taxes,   and  any
"Concessions" (as defined below). The determination of Current Market Rent shall
include  establishing  new Lease terms consistent with market terms at such time
relating to base rent,  base year, rent  escalations,  and pass throughs of real
estate taxes and operating  expenses,  to modify or replace as  appropriate  the
then existing  terms  contained in this Lease  relating to such items.  The term
"Concessions" means any free or reduced rent periods, construction allowances or
other concessions.

28.3 Initial  Negotiation  Period.Within ten (10) days after receipt of Tenant's
notice of its election to exercise the Renewal  Option,  Landlord  shall provide
Tenant with  Landlord's  good faith  determination  of the Current  Market Rent.
Tenant may accept or reject  such  determination  by Landlord  and shall  notify
Landlord in writing of it's  acceptance  or refection  within  fifteen (15) days
after Tenant's  receipt of Landlord's  determination of the Current Market Rent.
If Tenant so accepts  Landlord's  determination of the Current Market Rent, then
Tenant shall be bound to lease the  Premises  from  Landlord  during the Renewal
Period at the Current  Market  Rental so  determined  and,  within  fifteen (15)
business days after Landlord's receipt of Tenant written acceptance, the parties
shall execute a Lease amendment  reflecting such renewal, the new economic terms
and the Approved  Amendments,  but failure to execute such  amendment  shall not
affect the commencement of the Renewal Period or Tenant's obligation to pay rent
during the Renewal Period at the rate established pursuant to this Article.

28.4  Determination  of Rent by  Brokers  (i) If  Tenant  fails  to  agree  with
Landlord's  determination of the Current Market Rent within the fifteen (15) day
period set forth in Section 28.3, the Current Market Rent shall be determined by

<PAGE>

a panel of three (3) licensed real estate brokers, one of whom shall be named by
Landlord,  one by Tenant,  and the third selected by the two so appointed.  Each
member of the board of brokers  shall be licensed in Virginia as an  independent
real estate broker,  specializing  in the field of commercial  office leasing in
the northern  Virginia  metropolitan  area,  having no less than ten (10) years'
experience in such field,  and  recognized  as ethical and reputable  within the
field.  Landlord and Tenant shall each make its appointment within five (5) days
after the expiration of the fifteen (15) day period,  and shall notify the other
of its choice  within such time. If either party fails to select a broker within
such time,  the broker  selected by the other party shall  establish the Current
Market Rent. The two (2) brokers selected by Landlord and Tenant shall determine
the Current  Market Rent valuation  within ten (10) days after their  selection.
Should the two (2) brokers agree on a valuation then that valuation shall be the
Current  Market Rent.  In the event the two brokers  cannot agree on a valuation
within such ten (10) day period, then they shall promptly select a third broker.
If the brokers  selected by the parties  fail to select a third  broker five (5)
days after such ten (10) day valuation period, the parties may select such third
broker or either party may request such  appointment by the U.S.  District Court
for the Eastern  District of Virginia.  Within fifteen (15) days after the third
broker is selected,  the third broker shall determine the Current Market Rent in
accordance with the provisions above, and shall submit to the parties in writing
his or her  determination  of the Current  Market Rent.  The Current Market Rent
shall be (i) the third broker's  valuation,  if such valuation falls between the
valuations of the first two brokers;  or (ii) if the third brokers  valuation is
higher than the highest  valuation of the first two valuations  then the Current
Market Rent shall be the higher  valuation of the first two  brokers;  or if the
third  brokers  valuation  is lower than the lowest  valuation  of the first two
valuations  then the  Current  Market Rent shall be the lower  valuation  of the
first two  brokers,  and within ten (10) days  after such  determination  of the
Current  Market Rent,  Tenant shall notify  Landlord in writing  whether  Tenant
accepts such determination. If so accepted by Tenant, the parties shall be bound
by such decision.  If Tenant does not accept this  determination with the 10-day
period,  Tenant's exercise of the Renewal Option shall be revoked  automatically
and the Term shall expire on the Expiration  Date. In either case,  Landlord and
Tenant  shall each pay the fee of the broker  selected by it, and shall  equally
share the payment of the fee of the third broker.

              (ii) If Tenant  accepts the  determination  of Current Market Rent
pursuant to this Section 28.4,  then Tenant shall be bound to lease the Premises
from  Landlord  during  the  Renewal  Period  at the  Current  Market  Rental so
determined  and, within fifteen (15) business days after  Landlord's  receipt of
Tenant  written  acceptance,   the  parties  shall  execute  a  Lease  amendment
reflecting such renewal, the new economic terms and the Approved Amendments, but
failure to execute  such  amendment  shall not  affect the  commencement  of the
Renewal  Period or Tenant's  obligation to pay rent during the Renewal Period at
the rate established pursuant to this Article.

28.5 Paint and Carpet. As soon as practicable after  commencement of the Renewal
Period,  Landlord,  at its cost, will repaint the Premises with two (2) coats of
paint and will retile and recarpet the Premises.  The paint,  tile and carpet to
be used by Landlord  will be of  comparable  quality to those used in connection
with the construction of the Premises pursuant to the Work Agreement.

29.1 Option to Terminate  Lease. At any time during the seventh (7th) Lease Year
or thereafter, Tenant shall have the option to terminate this Lease with respect
to the entire  Premises in accordance  with the  provisions of this Article 4.3.
(the  "Termination  Option").  Tenant  shall  have  the  right to  exercise  the
Termination Option upon delivery to Landlord of (i) a written termination notice
from Tenant to Landlord (the  "Termination  Notice") given on or after the first
day of the seventh  (7th) Lease Year,  which notice shall  specify the effective
date of termination (the "Termination  Date"),  which date shall be at least two
hundred  seventy  (270) days  following  the date the  Termination  Notice is so
delivered to Landlord, and (ii) on the Termination Date so specified, cash in an
amount,  determined as of the Termination Date (the "Termination Fee"), equal to
all unamortized  Landlord costs relating to this Lease (including brokerage fees
and commissions,  tenant improvement allowances, and legal expenses), calculated
on a straight-line basis over the initial Term. If Tenant leases any other space
in the  Building  (including  Expansion  Space or First Offer  Space)  while the
Termination  Option  remains  in  effect,  then  the  Termination  Fee  shall be
calculated  on the basis such  unamortized  Landlord  costs not only related not
only to the original Premises hereunder but for all such other space as well. If
exercised by Tenant in accordance  with this  Article,  the  Termination  Option
shall  terminate  this  Lease  effective  as of the  close  of  business  on the
Termination Date specified in Tenant's Termination Notice.

29.2 Payment of all Rent  Through  Termination  Date.  If Tenant  exercises  its
Termination  Option,  Tenant shall pay, in addition to the Termination  Fee, all
Rent as and  when it  becomes  due  under  this  Lease up to and  including  the
Termination Date.

29.3 Inapplicable  during Renewal Period. The Termination Option shall lapse and
shall be of no further force and effect during any Renewal Period.

29.4 Tenant may not be in  Default.  If the  Termination  Option has been timely
exercised  but on the  Termination  Date there is an uncured Event of Default by
Tenant for which the  applicable  notice and cure  period,  if any, has not then
expired,  then if such Event of Default  shall be cured  within such  applicable
notice and cure period,  the Termination Date shall occur on the day immediately
following the date that Tenant  effects such cure.  Should such Event of Default
continue  beyond  such  notice  and cure  period,  then at  Landlord's  election
Tenant's  right to terminate this Lease under this Article shall lapse and be of
no further force and effect.

29.5 Time  is of the Essence.  Time shall be of  the essence with respect to all
of the time periods set forth in this Article.

"Expansion Space.")

30.2 Exercise of Expansion  Option;  Determination of Expansion Space. If Tenant
desires to exercise its expansion option, Tenant shall so notify Landlord within
the Expansion  Period.  Tenant's notice shall identify the approximate  size and
location of the space that  Tenant  desires to lease.  Upon  receipt of Tenant's
notice,  Landlord  shall work with  Tenant in good faith to agree upon the exact
size and location of the Expansion Space,  taking into account the space that is
available at that time and Landlord's reasonable marketing  requirements for the
remaining  vacant  space.  If the  parties are unable to agree upon the size and
location of the Expansion Space within ten (10) days after Landlord's receipt of
Tenant's notice, Tenant's expansion option shall expire.

30.3 Terms for Expansion  Space. The Expansion Space shall be leased on the same
terms and conditions as the Premises as though it had been leased along with the
Premises  as of the  Commencement  Date,  except that (i) the lease term for the
Expansion Space shall commence on the date that the space is delivered to Tenant
(the  "Expansion  Space  Commencement   Date"),  (ii)  if  the  Expansion  Space
Commencement Date falls within the first Lease Year, Base Rent for the Expansion
Space shall be calculated at the rate of $19.00 per rentable  square foot,  with

procedure  as is  provided  in the  Work  Agreement,  except  that  the  date of
substantial  completion  of  the  Expansion  Space  shall  be on or  before  the
Expansion Space  Commencement  Date, and (vi) Landlord may increase the Security
Deposit as it deems appropriate, in its reasonable judgment.

30.4 No Extension of Term. If Tenant leases the Expansion Space  hereunder,  the
Term of this Lease shall  remain  unchanged  from that  specified in Section 1.3
hereof.

30.5  Execution of Lease  Amendment.  The parties  shall execute an Amendment to
Lease  reflecting the lease of the Expansion Space within ten (10) business days
after Tenant  receives the Amendment from Landlord,  but failure to execute such
Amendment shall not affect the  commencement of the term for the Expansion Space
or Tenant's  obligation to pay rent for the Expansion  Space in accordance  with
this Article.

31.1 Grant of Right of First Offer. Subject to the terms of this Article, Tenant
shall have a right of first offer (the "First Offer Right") to negotiate for the
lease of any space in the Building  that becomes  available  for lease after the
expiration of the first Lease Year (each of such spaces being referred to as the
"First Offer Space").

31.2  Exercise  of Right of First  Offer.  If all or any part of the First Offer
Space  becomes  available  for lease at a time when the First  Offer Right is in
effect ("Available First Offer Space"), Landlord shall offer the Available First
Offer Space to Tenant  before  offering it to any other  party.  Landlord  shall
offer the Available First Offer Space to Tenant by submitting to Tenant a letter
of intent with respect  thereto,  identifying the date on which Landlord expects
the  Available  First Offer Space to be available  for  occupancy by Tenant (the
"First Offer Space Commencement Date"), and containing such terms and conditions
as are determined by Landlord,  in Landlord's reasonable  discretion,  acting in
good faith,  to be the market rate for  available  space in the  Building and in
other comparable  office buildings in the northern Virginia  metropolitan  area.
Tenant shall have the right within  thirty (30) days after Tenant  receives such
proposed  letter of intent to negotiate  the terms and  conditions  of a binding
letter of intent for such Available  First Offer Space (both Landlord and Tenant
acting in good faith) providing for a commencement date not later that the First
Offer Space Commencement Date specified in Landlord's proposed letter of intent;
provided  that if Landlord and Tenant fail to execute  such a binding  letter of
intent within such thirty (30) day period, then such Available First Offer Space
shall constitute "Rejected First Offer Space" within the meaning of Section 31.4
hereof.  The term for the First  Offer  Space  shall end on the same date as the
Term  for the  Premises;  provided,  however,  that  if the  First  Offer  Space
Commencement  Date will occur  within the last  three  Lease  Years of the Term,
Landlord may condition  the lease of the  Available  First Offer Space to Tenant
upon the extension of the  Expiration  Date for the entire  Premises to be three
(3) years  from the First  Offer  Space  Commencement  Date,  with Rent for such
additional  period being agreed to by Landlord and Tenant in the  negotiation of
the binding letter of intent.

31.3 Execution of Lease AmendmentThe parties shall execute an Amendment to Lease
reflecting  the lease of the  Available  First Offer Space  within ten (10) days
after Landlord and Tenant executes the binding letter of intent,  but failure to

<PAGE>

execute such  Amendment  shall not affect the  commencement  of the term for the
Available First Offer Space or Tenant's obligation to pay rent for the Available
First Offer Space in accordance with the letter of intent.

31.4 Rejected  First Offer Space.  Any  Available  First Offer Space that Tenant
fails to lease in accordance with this Article shall thereafter become "Rejected
First  Offer  Space."  Landlord  shall be free to  lease  all or any part of any
Rejected  First Offer Space to any other party without first offering all or any
part of the  Rejected  First Offer  Space to Tenant.  However,  if any  "Special
Rejected  First  Offer  Space" is so leased by  Landlord  to any other party and
later becomes  available  for lease during the Term,  then  notwithstanding  the
foregoing,  such Special  Rejected First Offer Space shall become and considered
as  Available  First Offer Space at the time such Special  Rejected  First Offer
Space so becomes  available for lease. As used herein,  "Special  Rejected First
Offer Space" means Available First Offer Space that becomes Rejected First Offer
Space during the first eighteen (18) full calendar months of the Term.

31.5 Subordinate to Existing Rights of Other Tenants.  Notwithstanding  anything
to the  contrary in this  Article,  no First  Offer  Space  shall be  considered
available for lease if (i) the tenant then  occupying the space desires to renew
its lease, whether pursuant to a renewal option or otherwise,  or (ii) the space
is subject to any other right of first offer,  first refusal or similar right of
another  tenant  (including  Crosswalk)  existing as of the  Commencement  Date.
Accordingly,  any such First  Offer  Space not  considered  available  for lease
pursuant to the  preceding  sentence  may be leased by Landlord to the  existing
tenant or party holding such other right without first offering it to Tenant.

31.6 Tenant may not be in Default. This Article shall apply only as long as this
Lease is in full  force and effect  and there is no  uncured  monetary  Event of
Default hereunder.

31.7  Time is of the Essence.  Time  shall be of the essence with respect to all
of the time periods set forth in this Article.

thereof,  shall comply with all Legal  Requirements.  If, at any time during the
Term,  the Antenna  does not comply with all Legal  Requirements,  Tenant  shall

Antenna  to  bring it into  compliance  with all  Legal  Requirements.  Tenant's
failure to obtain any permit required in order to initially install the Antenna,
or a subsequent  inability to maintain the Antenna for any reason, shall have no
effect on this  Lease  other than to  nullify  the right to install  and use the
Antenna.

32.4  Maintenance.  Landlord shall have the right to regulate and control access
to the roof by Tenant,  its  employees,  agents and  contractors.  At all times,

reasonable attorneys' fees) incurred as a result of permitting the placement and
operation of the Antenna on the roof and allowing access thereto.

workmanlike manner substantially in accordance with the Construction  Documents.

Law for Tenant to occupy the Premises.  Tenant will  cooperate  with Landlord as
necessary to obtain any such certificate of occupancy. Landlord will give Tenant
at least thirty (30) days' notice of the date upon which  Landlord  will deliver
possession of the Premises to Tenant.

delivering  possession of the Premises to Tenant in  accordance  with  this Work
Agreement  because  of a Tenant  Delay,  then, notwithstanding  Section 3 of the
Lease, the Commencement Date shall  be  the date (as  reasonably  determined  by
Landlord)  that Landlord would have delivered the Premises  to  Tenant  but  for
the  Tenant  Delay.

5.  Payment  for the  Tenant Improvements.

      5.1 Landlord shall provide Tenant with the Tenant  Allowance,  which shall
be used to pay for the cost of  completing  the Tenant  Improvements,  including
design  fees,  construction  costs,  and the  cost  of  obtaining  building  and
occupancy permits.  If there is an Excess Cost, Landlord shall so notify Tenant,
and Tenant  shall pay the  Excess  Cost to  Landlord  within ten (10) days after
Landlord's  notice  is  received.  Landlord  shall  make  all  payments  to  the
Contractors  and/or  Subcontractors  within ten (10) days of receipt of invoices

substance reasonably satisfactory to Landlord.

      5.2 In addition to the Tenant  Allowance,  Landlord shall pay for the cost
of any improvements to the base building (e.g.,  the bathrooms)  required by the
Americans with Disabilities Act or any regulations  promulgated  thereunder (the
"ADA"). All other ADA-related  improvements to the Premises shall be paid for by
Tenant, subject to the Tenant Allowance.

6.  Punchlist.  Before the Premises are delivered  to  Tenant,  Landlord, Tenant
and  Contractor  shall  make a  final inspection of the Premises to  ensure that
the Tenant Improvements have been made substantially in accordance with the Con-
struction Documents, at which time the Punchlist shall  be  prepared. Contractor
shall  complete  the  items  on the Punchlist  as  soon as practicable after the
Commencement Date.Within thirty (30) days after the Commencement Date the Tenant
shall have the right to submit to Landlord  a revised  Punchlist  setting  forth
any  deviation  from the  Plans  and  Specifications  and any work that does not
function properly.  The  Landlord shall cure all defects within thirty (30) days
of receipt of the revised Punchlist.

7.  Early Entry by Tenant; Coordination of Work.

      7.1 During the 30-day period before the Commencement Date,  Landlord shall
grant  Tenant  access to the  Premises  solely  for the  purpose  of  installing
telephone and computer cable and wiring,  fixtures,  furniture and related items
within the Premises.  During the 10-day period before the Commencement Date, the
Premises shall be  substantially  free of Landlord's  contractors.  Landlord may
exercise its  reasonable  discretion as to the timing of Tenant's early entry as
such timing  relates to the  completion of the Tenant  Improvements.  During any
periods of such early entry,  Tenant shall abide by all terms and  conditions of
this Lease  (including  all  insurance  requirements),  but Tenant  shall not be
required to pay Rent before the Commencement Date.

      8.1 Landlord will provide Tenant's  consultants with reasonable  access to
the Premises to inspect the progress of construction  and to install any Cabling
that needs to be installed before walls are closed.

lien against the property  and was  recorded  December 16, 1988,  in the Clerk's
Office of the Circuit Court of Fairfax County,  Virginia in Deed Book 7223, Page
1478 (the "Mortgage");

         AND WHEREAS,  it is a condition  of the loan  secured by said  Mortgage
that the  Mortgage  shall  unconditionally  be and remain at all times a lien or
charge upon the  Property,  prior and superior to the Lease and to the leasehold
estate created thereby;

         AND WHEREAS,  the parties hereto desire to assure  Tenant's  possession
and  control  of the  Demised  Premises  under  the  Lease  upon the  terms  and
conditions therein contained;

         NOW,  THEREFORE,  for and in  consideration of the mutual covenants and
premises  herein and other good and  valuable  consideration,  the  receipt  and
sufficiency of which is hereby acknowledged and agreed to by the parties hereto,
the parties hereto do hereby agree as follows:

                               A G R E E M E N T:

         1. The Lease is and shall be subject and  subordinate  to the Mortgage,
and to all renewals, modifications,  consolidations, replacements and extensions
thereof,  and  to all  future  advances  made  thereunder.  Notwithstanding  the
foregoing,  Tenant  agrees that at the option of the Lender,  upon notice to the
Tenant at any time and from time to time,  the Lease  shall be  superior  to the
Mortgage.  Such option of the Lender may be  exercised  an  unlimited  number of
times.

         2. Tenant  covenants and agrees with Lender that the Lease is presently
in good standing and in full force and effect and unmodified and that the Tenant
has  accepted  possession  of the  Demised  Premises  and that any  improvements
required  by the Lease to be made by the  Landlord  have been  completed  to the
satisfaction of the Tenant.
<PAGE>

         3.  Should  Lender  become  the owner of the  Property,  or should  the
Property  be sold by reason of  foreclosure,  or other  proceedings  brought  to
enforce the Mortgage,  or should the Property be  transferred by deed in lieu of
foreclosure,  or should any portion of the Property be sold under a trustee's or
judicial  sale or power of sale,  the Lease  shall  continue  in full  force and
effect as a direct  lease  between  the then owner of the  Property  and Tenant,
upon,  and subject to, all of the terms,  covenants and  conditions of the Lease
for the balance of the term thereof remaining,  including any extensions therein
provided.  Tenant does hereby  agree to attorn to Lender or to any such owner as
its landlord, and Lender hereby agrees that it will accept such attornment.

         4. Notwithstanding any other provision of this Agreement,  Lender shall
not be (a) liable for any  default of any  landlord  under the Lease  (including
Landlord),  accruing prior to the Lender  acquiring  title to the Property;  (b)
subject  to any  offsets or  defenses  which  have  accrued  prior to the Lender
acquiring  title to the Property , unless Tenant shall have  delivered to Lender
written  notice of the  default  which gave rise to such  offset or defense  and
permitted Lender the same right to cure such default as permitted Landlord under
the Lease;  (c) bound by any Rent that Tenant may have paid under the Lease more
than one month in advance;  (d) bound by any  amendment or  modification  of the
Lease hereafter made without Lender's prior written consent; (e) responsible for
the return of any security deposit delivered to Landlord under the Lease and not
subsequently received by Lender.

         5.  Tenant  shall give  written  notice to the Lender of any default of
Landlord  which would entitle  Tenant to cancel the Lease or reduce,  set-off or
abate the rent payable thereunder, and agrees that notwithstanding any provision
of the Lease, no notice of cancellation  thereof shall be effective and no right
of  set-off  shall be  exercised  unless  the  Lender  has  received  the notice
aforesaid  and has failed  within  thirty (30) days of the date  thereof to cure
same or, if the default cannot be cured within said thirty (30) days, has failed
to commence and to diligently  prosecute  the cure of  Landlord's  default which
gave rise to such right of cancellation or set-off.

         6. Should the Lender  acquire  possession of the Property,  it shall be
under no personal  liability with respect to any of the provisions of the Lease,
and if the Lender is in breach or default  with respect to its  obligations,  if
any,  under the Lease,  Tenant shall look solely to the equity of the Lender in,
and the income  arising  from,  the  Property for the  satisfaction  of Tenant's
remedies and in no event shall Tenant  attempt to secure or enforce any personal
judgment  against the Lender or against  any  employee or agent of the Lender by
reason of such default by the Lender.

         7. If Lender sends written notice to Tenant to direct its Rent payments
under the Lease to Lender instead of Landlord,  then Tenant agrees to follow the
instructions set forth in such written instructions and deliver Rent payments to
Lender,  whether  or not  Lender  takes  possession  of the  Property;  however,
Landlord and Lender agree that Tenant shall be credited  under the Lease for any
Rent payments received by Lender pursuant to such written notice.
<PAGE>

         8. In the  event  the  Lease  contains  a right of first  refusal  with
respect  to a sale  of the  Premises  or an  option  to  purchase  the  Premises
(collectively,  an "RFR/Option Proviso") such RFR/Option Proviso shall not apply
to any  foreclosure or  deed-in-lieu  of  foreclosure  relating to the Premises.
Moreover,  from and after any foreclosure or  deed-in-lieu of foreclosure,  said
RFR/Option Proviso shall automatically  terminate and be of no further force and
effect as if the RFR/Option Proviso had never been included in the Lease.

         9.  All  notices  which  may or are  required  to be  sent  under  this
Agreement shall be in writing and shall be sent by over-night messenger delivery
or first-class registered mail, postage prepaid,  return receipt requested,  and
sent to the party at the address  appearing  below or such other  address as any
party  shall  hereafter  inform the other party by written  notice  given as set

hereby.

                  C.  No  written  approval  of  any  federal,  state  or  local
governmental  authority  is  necessary  to  carry  out  the  terms  of the  Loan
Agreement,  the Security  Agreement or the Note and no consents or approvals are
required  in the  making or  performance  of the Loan  Agreement,  the  Security
Agreement or the Notes.

                  D. Except as  previously  disclosed to Lender in writing,  the
audited  consolidated  balance  sheet  of the  Borrower  and  Guarantors,  as of
December 31, 1998,  is true and correct and the  consolidated  balance  sheet of
Borrower and Guarantors,  dated as of September 30, 1999, and related  statement
of income for the quarter then ended,  a copy of which has been  provided to the
Lender, is true and correct,  subject to normal, year end adjustments and fairly
presents  the  financial  condition  of  the  Borrower  and  Guarantors,  all in
accordance with Generally Accepted Accounting  Principles ("GAAP")  consistently
applied and since  September 30, 1999, no material  adverse change in Borrower's
and  Guarantors'   financial  condition  or  business  operation  has  occurred.
Provided,  however,  that  Lender  acknowledges  that  Acquisition  was  not  in
existence  until after  September 30, 1999 and that GEC's  financial  statements
previously have not been prepared in accordance with GAAP.

                  E. Except as previously disclosed to Lender in writing,  there
are no pending or threatened actions or proceedings before any court, arbitrator
or governmental or administrative body or agency which may materially  adversely
affect the  properties,  business  or  condition,  financial  or  otherwise,  of
Borrower or Guarantors or in any way adversely  affect or call into question the
power and the  authority of Borrower or  Guarantors to enter into or perform the
Loan Agreement, the Notes or the Security Agreement.

                  F. No part of the  proceeds of advances  made  pursuant to the
Loan Agreement  will be or have been used to purchase or carry,  or to reduce or
retire any loan  incurred to purchase or carry,  any margin  stocks  (within the
meaning of Regulation U of the Board of Governors of the Federal Reserve System)
or to extend credit to others for the purpose of purchasing or carrying any such
margin stocks.  Borrower is not engaged in the business of extending  credit for
the purpose of purchasing or carrying  such margin  stocks.  If requested by the
Lender,  Borrower shall furnish to the Lender,  in connection with the loan made
hereunder,  a statement in conformance  with the requirements of Federal Reserve
Form U-l referred to in said Regulation. In addition, no part of the proceeds of
the loan  made  hereunder  will be used for the  purchase  of  commodity  future
contracts  (or margins  therefor for short sales) for any commodity not required
for the normal raw material inventory of the Borrower.

                  G. Borrower and  Guarantors as a  consolidated  entity are now
solvent and able to pay their debts as they mature and Borrower  and  Guarantors
collectively  now own  property  whose fair  salable  value is greater  than the
amount required to pay their Indebtedness.

                  H.  Borrower  has not  incurred  any  material or  accumulated
funding deficiency within the meaning of the Employee Retirement Income Security
Act of  1974 or any  liability  to the  Pension  Benefit  Guarantee  Corporation
established  under  such  Act (or  any  successor  thereto  under  such  Act) in
connection  with any employee  benefit plan  established  or  maintained  by the
Borrower.

                  I. Each of the  representations and warranties of the Borrower
contained in the Security  Agreement are hereby reaffirmed in all respects as of
the date hereof.

                  J.  Neither  this  Loan  Agreement  nor any  other  Agreements
contain any  misrepresentation or untrue statement of fact or omits to state any
material  fact  necessary to make any of such  agreements,  reports,  schedules,
certificates or instruments not misleading.

                  K. Borrower has good,  indefeasible and merchantable  title to
the  Collateral,  free and clear of all liens,  claims,  security  interests and
encumbrances  except as included on the balance sheet or otherwise  disclosed to
Lender in writing.

                  L. Borrower have good and  marketable  title to its properties
and assets,  including the properties and assets  reflected in the balance sheet
described above,  except for such assets as have been disposed of since the date
of said  financial  statements as no longer used or useful in the conduct of its
business or as have been disposed of in the ordinary course of business, and all
such properties and assets are free and clear of all liens, mortgages,  pledges,
encumbrances  or charges  except as included on the balance  sheet or  otherwise
disclosed to Lender in writing.

                  M. Except as disclosed to Lender in writing,  neither Borrower
nor Guarantors are parties to nor are they bound by any contract or agreement or
subject to any charter or other corporate  restrictions  which adversely  affect
the business,  properties or condition,  financial or otherwise,  of Borrower or
Guarantors except as disclosed in the financial statements  referenced above and
notes thereto.

                  N. Borrower and Guarantors  own,  possess or have the right to
use all necessary patents, licenses, trademarks,  trademark rights, trade names,
trade name rights and  copyrights  material to the conduct of its businesses now
conducted,  without known conflict with any patent,  license,  trademark,  trade
name or copyright of any other Person.

                  The  effectiveness  of this Loan Agreement shall be subject to
the continuing  accuracy of all  representations  and warranties of the Borrower
and Guarantors contained herein.  Borrower and Guarantors covenant,  warrant and
represent to the Lender that all  representations and warranties of Borrower and
Guarantors  contained  in this  Loan  Agreement  shall  be  true at the  time of
execution of the Loan  Agreement and the Other  Agreements and shall survive the
execution,  delivery  and  acceptance  thereof by the  parties  thereto  and the
closing of the transactions described therein or related thereto.

                                   ARTICLE IV
                              AFFIRMATIVE COVENANTS


                  The Borrower and each  Guarantor  further agrees that, so long
as any  Liabilities  remain unpaid to Lender,  it will comply with the following
requirements:

                  A. As soon as practicable, in any event within forty-five (45)
days after the end of each calendar  quarter of each calendar  year,  deliver or
cause to be delivered to the Lender a consolidated balance sheet of Borrower and
Guarantors as at the last day of such quarter and related consolidated statement
of  income  for  such  quarter  and  cumulative  year to date for  Borrower  and

<PAGE>


                  B. As soon as practicable  and in any event within ninety (90)
days after the end of each Fiscal Year, deliver to the Lender (i) a consolidated
balance sheet of Borrower and  Guarantors as at the end of such Fiscal Year, and
related  consolidated  statements of income and retained earnings and changes in
financial  position for such Fiscal Year, setting forth in each case comparative
form figures for the  corresponding  period in the preceding Fiscal Year, all in
reasonable  detail and  satisfactory in scope to the Lender and certified by and
containing an unqualified opinion of a nationally recognized firm of independent
certified public accountants,  and (ii) management letters, if any, delivered to
the Borrower by such  independent  certified public  accountants,  in connection
with their examination of such financial statements.

                  C.  Together  with each  delivery of those  items  required by
Paragraphs A. and B., above,  Borrower  shall deliver to the Lender an officer's
certificate setting forth: (i) to the best of his knowledge,  Borrower has kept,
observed,  performed  and  fulfilled  each and every  agreement  binding  on and
contained  in this  Loan  Agreement  and is not at the  time in  default  of the
keeping, observance,  performance or fulfillment of any of the terms, provisions
and conditions hereof, and (ii) that no Default or Event of Default, as has been
specified  below,  has  occurred or  specifying  all such  Defaults or Events of
Default which they may have knowledge.

                  D.  With  reasonable   promptness,   deliver  such  additional
financial  or other  date as the Lender may  reasonably  request.  The Lender is
hereby  authorized  to deliver a copy of any  financial  statements or any other
information  relating to the business  operations or financial  condition of the
Borrower and  Guarantors  which may be furnished to it or come to its  attention
pursuant to this Loan Agreement or otherwise,  to any regulatory  body or agency
having  jurisdiction over the Lender or to any Person which shall, or shall have
the right or obligation,  to succeed to all or any part of the Lender's interest
in the Notes or Other Agreements.

                  E. Promptly pay or cause to be paid all taxes, assessments and
other  governmental  charges  that may  lawfully be levied or assessed  upon the
income or profits of Borrower; provided, however, Borrower shall not be required
to pay any such tax,  assessment,  charge, levy or claim so long as the validity
thereof  shall be actively  contested in good faith by proper  proceedings;  but
provided further that any such tax,  assessment,  charge, levy or claim shall be
paid,  stayed  or bonded  forthwith  upon the  commencement  of  proceedings  to
foreclose any lien securing the same.

                  F. Do or cause to be done all things necessary to preserve and
to keep in full force and effect its corporate existence and rights.



<PAGE>


                  G. At its  sole  cost  and  expense,  keep  and  maintain  the
Collateral  insured for its full insurable  value against loss or damage,  fire,
theft,  explosion and all other hazards and risk  ordinarily  insured against by
other owners or users of such  properties  in similar  businesses,  and maintain
adequate workers' compensation insurance,  and notify the Lender promptly of any
event or  occurrence  causing a  material  loss or  decline  in the value of the
Collateral  and the estimated (or actual,  if available)  amount of such loss or
decline. All policies of insurance shall be in form and with insurers recognized
as adequate by prudent  business  persons and all such policies shall be in such
amounts as may be satisfactory to the Lender. Upon request,  the Lender shall be
delivered  the original  (or  certified  copy) of each policy of  insurance  and
evidence of payment of all premiums  therefor.  Such policies of insurance shall
contain an endorsement,  in form and substance acceptable to the Lender, showing
loss  payable to the Lender.  Such  endorsement,  or an  independent  instrument
furnished to the Lender,  shall provide that the insurance  companies  will give
the Lender at least thirty (30) days prior written notice before any such policy
or policies of insurance shall be altered or canceled and that no act or default
of Borrower or any other  person  shall affect the right of the Borrower to loss
or  damage.  Borrower  and  Guarantors  hereby  direct all  insurers  under such
policies of insurance where loss or damage exceeds $25,000 under any such policy
of insurance to pay all proceeds payable  hereunder  directly to the Lender.  So
long as no Default or Event of Default  exists  hereunder,  at the option of the
Borrower,  in the case of insurance  proceeds arising from the loss or damage of
building and  equipment,  the  proceeds may be used to replace or restore  same.
Should the  Borrower  elect not to replace or  restore  the lost  property,  any
insurance  proceeds  shall be applied  first to any accrued  interest due to the
Lender,  then to the principal  balance of the  liabilities in such order as the
Borrower may direct.  Borrower  irrevocably makes,  constitutes and appoints the
Lender (and all officers,  employees or agents designated by the Lender) as such
Borrower's  true and lawful  attorney (and  agent-in-fact),  effective  from and
after the  occurrence  of a Default  or Event of  Default,  for the  purpose  of
making,  settling  and  adjusting  such claim under the  policies  of  insurance
(providing  that the Lender shall consult with Borrower prior to finally making,
settling or adjusting  claims under such policies of  insurance),  endorsing the
name of Borrower on any check,  draft or instrument or other item or payment for
the proceeds of such policies of insurance and for making all determinations and
decisions with respect to such policies of insurance.  In the event Borrower, at
any time or times  hereafter,  shall fail to  maintain  any of the  policies  of
insurance  required  above or to pay any  premium  in  whole or in part  related
thereto, then the Lender, without waiving or releasing any obligation or default
by Borrower  hereunder,  may (but shall be under no  obligation to do so) at any
time or times  hereafter  obtain and take any other action with respect  thereto
which the Bank deems advisable.  All sums so disbursed by the Lender,  including
reasonably  attorneys'  fees,  court costs,  expenses and other charges relating
thereto,  shall be  payable,  on demand  by  Borrower  and  shall be  additional
Liabilities  hereunder  secured by the  Collateral.  The  Lender  agrees to give
Borrower  notice  of  payment  of each and every  premium  paid by  Borrower  to
insurers as required hereunder.

                  H.  Maintain  its  property  in good order and repair and from
time to time  make all  needful  and  proper  repairs,  renewals,  replacements,
additions and improvements thereto.

                  I. Keep true books of record and account in which  full,  true
and correct entries will be made of all of its dealings and transactions and set
up on its  books  such  reserves  as  may  be  required  by  Generally  Accepted
Accounting Principles.

                  J. Conform to and duly observe all laws, regulations and other
valid  requirements  of any regulatory  authority with respect to the conduct of
its business.

                  K. Upon any officer of the  Borrower or  Guarantors  obtaining
knowledge  of a  Default  or Event of  Default  hereunder  or  under  any  other
obligation of Borrower or Guarantors,  cause such officer or individual,  as the
case may be, to  properly  deliver to the Lender a  certificate  certifying  the
nature  thereof,  the  period of  existence  thereof,  and  whatever  action the
Borrower proposes to take with respect thereto.

                  L. Upon any officer of the  Borrower or  Guarantors  obtaining
knowledge of a material  litigation,  dispute or proceedings being instituted or
threatened against Borrower or Guarantors, or any attachment, levy, execution or
other process  being  instituted  against any assets of Borrower or  Guarantors,
cause such officer or individual,  as the case may be, to promptly give the Bank
written notice of such litigation, dispute, proceeding, levy, execution or other
process.

                  M. Use it best efforts to comply with all of the  requirements
of the Employee  Retirement Income Security Act of 1974 (ERISA) applicable to it
and  furnished to the Lender a statement of the principal  financial  officer of
Borrower  describing in reasonable  detail any  Reportable  Event (as defined in
ERISA).

                               NEGATIVE COVENANTS

1999).

                  B.  Incur,  create,  assume or  permit to exist any  mortgage,

                               SPECIFIC PROVISIONS


                  A.  Revolving  Loan  Amount.   The  maximum  principal  amount
outstanding  under the Revolving Loan at any time shall not exceed the lesser of
the  Borrowing  Base (as  defined in Exhibit 1 below) or Three  Million  Dollars
($3,000,000.00).  On or before the first  business day of each  calendar  month,
Borrower  and the Other  Subsidiaries  shall  furnish to the  Lender,  in a form
satisfactory  to the  Lender,  a current  Borrowing  Base  Certificate  with all
calculations and documentation necessary to determine the current Borrowing Base
and the Borrowing  Base set forth  therein  shall be deemed the  Borrowing  Base
until receipt and approval by Lender of a new Borrowing Base Certificate.

                  B. Revolving  Loan and Term Loan Interest Rate.  Except upon a
Default,  the interest rate for the Revolving Loan and Term Loan may be adjusted
from time to time as follows:

                           1. If Exigent's most recent Form 10Q report furnished
to Lender indicates the following  ratios:  Total Liabilities to Total Net Worth
less than  1.50:1.0  and Working  Capital in excess of  $2,500,000.00,  then the
interest rate  otherwise  stated for the Revolving  Loan (but not the Term Loan)

                           2. If Exigent's most recent Form 10Q report furnished
to Lender indicates the following
ratios:  Total  Liabilities  to Total Net Worth less than  1.00:1.0  and Working
Capital in excess of $3,500,000.00,  then the interest rate otherwise stated for
the  Revolving  Loan (but not the Term  Loan)  shall be reduced by 0.75% for the

the applicable interest rate under
both the  Revolving  Loan and Term Loan for such  calendar  quarter  will be the
Prime  Rate or the Daily  Fluctuating  LIBO Rate plus  2.50% (as such  terms are
defined in the Notes) by providing  written notice of such election to Lender at
least  fifteen  (l5) days prior to the end of the  preceding  calendar  quarter;

stay such judgment shall not have been discharged,  then at any time thereafter,
the Lender may, at its option, declare the Notes and all other Liabilities owing

are expressly  waived,  anything  contained herein or in the Other Agreements to
the contrary notwithstanding, and in addition the Lender may immediately proceed

                                  ARTICLE VIII
                               GENERAL PROVISIONS


                  A. The Borrower further agrees to reimburse the Lender for all
costs  and  out-of-pocket  expenses,  including  fees  of the  Lender's  special
counsel,  incurred in  connection  with the  preparation,  execution,  delivery,
modification,  waiver and amendments of this Loan  Agreement,  the Notes and the
related  documentation,  and also all reasonable expenses incurred by the Lender
(including  reasonable  attorneys'  fees) in the collection of any  Indebtedness
incurred hereunder in the event of default by Borrower.

                  B. Borrower agrees to pay any and all documentary,  intangible
stamp or excise  taxes now or after  payable in  respect of the Loan,  this Loan
Agreement or Other Agreements or any  modifications  thereof and hold the Lender
harmless with respect  thereto.  The Borrower further agrees that the Lender may
deduct from any advance the amount of any such  documentary or intangible  stamp
tax payable with respect to such  advance,  the decision of the Lender as to the
amount  thereof to be  conclusive,  absent  manifest  error.  Borrower gives the
Lender the  authority to debit its accounts  maintained  with the Lender for any
principal, interest, fees or other Liabilities becoming due hereunder.

                  C. This Loan Agreement sets forth the entire understanding and
agreement  of the parties  hereto in relation to the subject  matter  hereof and
supersedes any prior  negotiations  and agreements among the parties relative to
such subject matter. No promise, condition,  representation or warranty, express
or implied,  not herein set forth shall bind any party hereto,  and none of them
has relied on any such promise,  condition,  representation or warranty. Each of
the parties hereto acknowledges that, except as in this Loan Agreement otherwise
expressly  stated,  no  representations,  warranties or commitments,  express or
implied,  have been made by any other  party to the other.  None of the terms or
conditions of this Loan Agreement may be changed,  modified,  waived or canceled
orally or  otherwise,  except by  writing,  signed  by all the  parties  hereto,
specifying  such change,  modification,  waiver or cancellation of such terms or
conditions, or of any preceding or succeeding breach thereof.

                  D.  Notwithstanding  any other provision herein, the aggregate
interest  rate  charged  under  the  Notes,  including  all  charges  or fees in
connection  therewith  deemed in the nature of interest under Florida law, shall
not exceed the maximum  rate  allowed by law.  In the event the stated  interest
rate on the Notes  together with any other charge or fee deemed in the nature of
interest exceeds the maximum legal rate, then the Lender shall have the right to
make such adjustments as are necessary to reduce the aggregate  interest rate to
the maximum  legal rate.  The Borrower  waives any right to prior notice of such
adjustment  and further  agrees that such  adjustment  may be made by the Lender
subsequent to  notification  from Borrower that the aggregate  interest  charged
exceeds the maximum legal rate.



<PAGE>


                  E. This Loan Agreement,  the Security  Agreement and the Notes
issued hereunder shall be governed in all respects by the laws of Florida.

                  F.  Should  any  one or more of the  provisions  of this  Loan
Agreement be determined to be illegal or  unenforceable as to one or more of the
parties, all other provisions nevertheless shall remain effective and binding on
the parties hereto.

                  G. Borrower and Lender  hereby  consent and agree that, in any
actions  predicated  upon this  Agreement,  venue is  properly  laid in  Brevard
County,  Florida,  and that the Circuit Court for Brevard County,  Florida shall
have full  jurisdiction  to determine all issues arising out of or in connection
with the execution and  enforcement of this  Agreement.  Borrower  waives to the
fullest  extent  permitted  under the laws of the State of  Florida,  any right,
power or  privilege  to demand a jury trial  with  respect to any and all issues
arising out of or in connection  with the execution  and/or  enforcement of this
Agreement.

                  H. Borrower  warrants to Lender that, on and after the date of
this  Agreement,  so long as any of the  indebtedness  under the  Notes  remains
unpaid, Borrower and any material subsidiaries of Borrower (hereinafter referred
to as the  "Organization") are Year 2000 Compliant.  As used herein,  "Year 2000
Compliant"  shall  mean  that  all  software,   embedded  microchips  and  other
processing  capabilities  utilized by the Organization or the Organization's key
suppliers,  vendors  and  customers  the  failure of which would have a material
adverse effect on the Organization or the key supplier, vendor or customer, will
correctly process, sequence, and calculate,  without interruption,  all date and
date related data for all dates to, through and after January 1, 2000, including
leap year calculations,  and shall recognize,  store and transmit date data in a
format which clearly  indicates the correct  century.  Borrower shall deliver to
Lender, upon Lender's reasonable request, all periodic internally and externally
prepared  evaluations and progress reports  concerning the  Organization's  Year
2000 plan and Year 2000 readiness and such other information,  documentation and
materials as Lender may reasonably request from time to time in order to confirm
that the  Organization  is Year 2000  Compliant  and the  method(s)  used by the
Organization to become Year 2000 Compliant.

                  IN WITNESS  WHEREOF,  Borrower and Lender have hereunto caused
these presents to be executed on the date first above written.

and Guarantors make the following representations and warranties:

                  A. Borrower is a corporation  duly organized,  existing and in
good  standing  under the laws of the State of  Florida,  and has the  corporate
power to own property and to carry out its businesses now being  conducted,  and
is duly qualified as a foreign  corporation to do business in every jurisdiction

of law to execute and  deliver the Note and to execute,  deliver and perform the
Loan  Agreement and the Security  Agreement,  all  corporate  action on its part
required for the lawful  execution,  delivery and  performance  thereof has been
duly taken and the Loan Agreement, the Security Agreement and the Note, upon the
due  execution  and  delivery  thereof,   will  be  the  valid  and  enforceable
instruments and obligations of Borrower in accordance with their terms.  Neither
the execution of the Loan Agreement,  the Security Agreement nor the creation or
issuance of the Note, nor the fulfillment of or compliance with their provisions
and terms will conflict with, or result in a breach of the terms,  conditions or
provisions of, or constitute a violation of or default under any applicable law,
regulation,  order,  writ or decree of the charter or bylaws of the  Borrower or
any agreement or instrument to which Borrower is now a party or create any lien,
charge or encumbrance upon any of the property or assets of Borrower pursuant to
the terms of any  agreement  or  instrument  to which  Borrower is a party or by
which it is bound other than the security interest contemplated hereby.

governmental  authority  is  necessary  to  carry  out  the  terms  of the  Loan
Agreement,  the Security  Agreement or the Note and no consents or approvals are
required  in the  making or  performance  of the Loan  Agreement,  the  Security
Agreement or the Note.

                  D. Except as  previously  disclosed to Lender in writing,  the
audited  consolidated  balance  sheet  of the  Borrower  and  Guarantors,  as of
December 31, 1998,  is true and correct and the  consolidated  balance  sheet of
Borrower and Guarantors,  dated as of September 30, 1999, and related  statement
of income for the quarter then ended,  a copy of which has been  provided to the
Lender, is true and correct,  subject to normal, year end adjustments and fairly
presents  the  financial  condition  of  the  Borrower  and  Guarantors,  all in
accordance with Generally Accepted Accounting  Principles ("GAAP")  consistently
applied and since  September 30, 1999, no material  adverse change in Borrower's
and  Guarantors'   financial  condition  or  business  operation  has  occurred.
Provided,  however,  that  Lender  acknowledges  that  Acquisition  was  not  in
existence  until after  September 30, 1999 and that GEC's  financial  statements
previously have not been prepared in accordance with GAAP.

                  E. Except as previously disclosed to Lender in writing,  there
are no pending or threatened actions or proceedings before any court, arbitrator
or governmental or administrative body or agency which may materially  adversely
affect the  properties,  business  or  condition,  financial  or  otherwise,  of
Borrower or Guarantors or in any way adversely  affect or call into question the
power and the  authority of Borrower or  Guarantors to enter into or perform the
Loan Agreement, the Note or the Security Agreement.

                  F. No part of the  proceeds of advances  made  pursuant to the
Loan Agreement  will be or have been used to purchase or carry,  or to reduce or
retire any loan  incurred to purchase or carry,  any margin  stocks  (within the
meaning of Regulation U of the Board of Governors of the Federal Reserve System)
or to extend credit to others for the purpose of purchasing or carrying any such
margin stocks.  Borrower is not engaged in the business of extending  credit for
the purpose of purchasing or carrying  such margin  stocks.  If requested by the
Lender,  Borrower shall furnish to the Lender,  in connection with the loan made
hereunder,  a statement in conformance  with the requirements of Federal Reserve
Form U-l referred to in said Regulation. In addition, no part of the proceeds of
the loan  made  hereunder  will be used for the  purchase  of  commodity  future
contracts  (or margins  therefor for short sales) for any commodity not required
for the normal raw material inventory of the Borrower.

                  G. Borrower and  Guarantors as a  consolidated  entity are now
solvent and able to pay their debts as they mature and Borrower  and  Guarantors
collectively  now own  property  whose fair  salable  value is treater  than the
amount required to pay their Indebtedness.

                  H.  Borrower  has not  incurred  any  material or  accumulated
funding deficiency within the meaning of the Employee Retirement Income Security
Act of  1974 or any  liability  to the  Pension  Benefit  Guarantee  Corporation
established  under  such  Act (or  any  successor  thereto  under  such  Act) in
connection  with any employee  benefit plan  established  or  maintained  by the
Borrower.

                  I. Each of the  representations and warranties of the Borrower
contained in the Security  Agreement are hereby reaffirmed in all respects as of
the date hereof.

                  J.  Neither  this  Loan  Agreement  nor any  other  Agreements
contains any misrepresentation or untrue statement of fact or omits to state any
material  fact  necessary to make any of such  agreements,  reports,  schedules,
certificates or instruments not misleading.

                  K. Borrower has good,  indefeasible and merchantable  title to
the  Collateral,  free and clear of all liens,  claims,  security  interests and
encumbrances  except as included on the balance sheet or otherwise  disclosed to
Lender in writing.

                  L. Borrower has good and  marketable  title to its  properties
and assets,  including the properties and assets  reflected in the balance sheet
described above,  except for such assets as have been disposed of since the date
of said  financial  statements as no longer used or useful in the conduct of its
business or as have been disposed of in the ordinary course of business, and all
such properties and assets are free and clear of all liens, mortgages,  pledges,
encumbrances  or charges  except as included on the balance  sheet or  otherwise
disclosed to Lender in writing.



<PAGE>


                  M. Except as disclosed to Lender in writing,  neither Borrower
nor Guarantors are parties to nor are they bound by any contract or agreement or
subject to any charter or other corporate  restrictions  which adversely  affect
the business,  properties or condition,  financial or otherwise,  of Borrower or
Guarantors except as disclosed in the financial statements  referenced above and
notes thereto.

                  N. Borrower and Guarantors  own,  possess or have the right to
use all necessary patents, licenses, trademarks,  trademark rights, trade names,
trade name rights and  copyrights  material to the conduct of its businesses now
conducted,  without known conflict with any patent,  license,  trademark,  trade
name or copyright of any other Person.

represent to the Lender that all  representations and warranties of Borrower and

                                   ARTICLE IV
                              AFFIRMATIVE COVENANTS


                  The Borrower and each  Guarantor  further agrees that, so long
as any  Liabilities  remain unpaid to Lender,  it will comply with the following
requirements:

                  A. As soon as practicable, in any event within forty-five (45)
days after the end of each calendar  quarter of each calendar  year,  deliver or
cause to be delivered to the Lender a consolidated balance sheet of Borrower and
Guarantors as at the last day of such quarter and related consolidated statement
of  income  for  such  quarter  and  cumulative  year to date for  Borrower  and

certified  by an  authorized  officer  of  Borrower  to have  been  prepared  in

days after the end of each Fiscal Year, deliver to the Lender (i) a consolidated
balance sheet of Borrower and  Guarantors as at the end of such Fiscal Year, and

containing an unqualified opinion of a nationally recognized firm of independent
certified public accountants,  and (ii) management letters, if any, delivered to
the Borrower by such  independent  certified public  accountants,  in connection
with their examination of such financial statements.

                  C.  Together  with each  delivery of those  items  required by
Paragraphs A. and B., above,  Borrower  shall deliver to the Lender an officer's
certificate setting forth: (i) to the best of his knowledge,  Borrower has kept,
observed,  performed  and  fulfilled  each and every  agreement  binding  on and
contained  in this  Loan  Agreement  and is not at the  time in  default  of the
keeping, observance,  performance or fulfillment of any of the terms, provisions
and conditions hereof, and (ii) that no Default or Event of Default, as has been
specified  below,  has  occurred or  specifying  all such  Defaults or Events of
Default which they may have knowledge.

                  D.  With  reasonable   promptness,   deliver  such  additional
financial  or other  date as the Lender may  reasonably  request.  The Lender is
hereby  authorized  to deliver a copy of any  financial  statements or any other
information  relating to the business  operations or financial  condition of the
Borrower and  Guarantors  which may be furnished to it or come to its  attention
pursuant to this Loan Agreement or otherwise,  to any regulatory  body or agency

other  governmental  charges  that may  lawfully be levied or assessed  upon the
income or profits of Borrower; provided, however, Borrower shall not be required
to pay any such tax,  assessment,  charge, levy or claim so long as the validity
thereof  shall be actively  contested in good faith by proper  proceedings;  but
provided further that any such tax,  assessment,  charge, levy or claim shall be
paid,  stayed  or bonded  forthwith  upon the  commencement  of  proceedings  to
foreclose any lien securing the same.

                  F. Do or cause to be done all things necessary to preserve and
to keep in full force and effect its  corporate existence and rights.



<PAGE>


                  G. At its  sole  cost  and  expense,  keep  and  maintain  the
Collateral  insured for its full insurable  value against loss or damage,  fire,
theft,  explosion and all other hazards and risk  ordinarily  insured against by
other owners or users of such  properties  in similar  businesses,  and maintain
adequate workers' compensation insurance,  and notify the Lender promptly of any
event or  occurrence  causing a  material  loss or  decline  in the value of the
Collateral  and the estimated (or actual,  if available)  amount of such loss or
decline. All policies of insurance shall be in form and with insurers recognized
as adequate by prudent  business  persons and all such policies shall be in such
amounts as may be satisfactory to the Lender. Upon request,  the Lender shall be
delivered  the original  (or  certified  copy) of each policy of  insurance  and
evidence of payment of all premiums  therefor.  Such policies of insurance shall
contain an endorsement,  in form and substance acceptable to the Lender, showing
loss  payable to the Lender.  Such  endorsement,  or an  independent  instrument
furnished to the Lender,  shall provide that the insurance  companies  will give
the Lender at least thirty (30) days prior written notice before any such policy
or policies of insurance shall be altered or canceled and that no act or default
of Borrower or any other  person  shall affect the right of the Borrower to loss
or  damage.  Borrower  and  Guarantors  hereby  direct all  insurers  under such
policies of insurance where loss or damage exceeds $25,000 under any such policy
of insurance to pay all proceeds payable  hereunder  directly to the Lender.  So
long as no Default or Event of Default  exists  hereunder,  at the option of the
Borrower,  in the case of insurance  proceeds arising from the loss or damage of
building and  equipment,  the  proceeds may be used to replace or restore  same.
Should the  Borrower  elect not to replace or  restore  the lost  property,  any
insurance  proceeds  shall be applied  first to any accrued  interest due to the
Lender,  then to the principal  balance of the  liabilities in such order as the
Borrower may direct.  Borrower  irrevocably makes,  constitutes and appoints the
Lender (and all officers,  employees or agents designated by the Lender) as such

                                  ARTICLE VIII
                               GENERAL PROVISIONS


                  A. The Borrower further agrees to reimburse the Lender for all

incurred hereunder in the event of default by Borrower.

                  B. Borrower agrees to pay any and all documentary,  intangible
stamp or excise  taxes now or after  payable in  respect of the Loan,  this Loan
Agreement or Other Agreements or any  modifications  thereof and hold the Lender
harmless with respect  thereto.  The Borrower further agrees that the Lender may
deduct from any advance the amount of any such  documentary or intangible  stamp
tax payable with respect to such  advance,  the decision of the Lender as to the
amount  thereof to be  conclusive,  absent  manifest  error.  Borrower gives the
Lender the  authority to debit its accounts  maintained  with the Lender for any
principal, interest, fees or other Liabilities becoming due hereunder.



<PAGE>


                  C. This Loan Agreement sets forth the entire understanding and
agreement  of the parties  hereto in relation to the subject  matter  hereof and
supersedes any prior  negotiations  and agreements among the parties relative to
such subject matter. No promise, condition,  representation or warranty, express
or implied,  not herein set forth shall bind any party hereto,  and none of them
has relied on any such promise,  condition,  representation or warranty. Each of
the parties hereto acknowledges that, except as in this Loan Agreement otherwise
expressly  stated,  no  representations,  warranties or commitments,  express or
implied,  have been made by any other  party to the other.  None of the terms or
conditions of this Loan Agreement may be changed,  modified,  waived or canceled
orally or  otherwise,  except by  writing,  signed  by all the  parties  hereto,
specifying  such change,  modification,  waiver or cancellation of such terms or
conditions, or of any preceding or succeeding breach thereof.

                  D.  Notwithstanding  any other provision herein, the aggregate
interest  rate  charged  under  the  Note,  including  all  charges  or  fees in
connection  therewith  deemed in the nature of interest under Florida law, shall
not exceed the maximum  rate  allowed by law.  In the event the stated  interest
rate on the Note  together  with any other charge or fee deemed in the nature of
interest exceeds the maximum legal rate, then the Lender shall have the right to
make such adjustments as are necessary to reduce the aggregate  interest rate to
the maximum  legal rate.  The Borrower  waives any right to prior notice of such
adjustment  and further  agrees that such  adjustment  may be made by the Lender
subsequent to  notification  from Borrower that the aggregate  interest  charged
exceeds the maximum legal rate.

                  E. This Loan  Agreement,  the Security  Agreement and the Note
issued hereunder shall be governed in all respects by the laws of Florida.

                  F.  Should  any  one or more of the  provisions  of this  Loan
Agreement be determined to be illegal or  unenforceable as to one or more of the
parties, all other provisions nevertheless shall remain effective and binding on
the parties hereto.

                  G. Borrower and Lender  hereby  consent and agree that, in any
actions  predicated  upon this  Agreement,  venue is  properly  laid in  Brevard
County,  Florida,  and that the Circuit Court for Brevard County,  Florida shall
have full  jurisdiction  to determine all issues arising out of or in connection
with the execution and  enforcement of this  Agreement.  Borrower  waives to the
fullest  extent  permitted  under the laws of the State of  Florida,  any right,
power or  privilege  to demand a jury trial  with  respect to any and all issues
arising out of or in connection  with the execution  and/or  enforcement of this
Agreement.

                  H. Borrower  warrants to Lender that, on and after the date of
this  Agreement,  so long as any of the  indebtedness  under the  Notes  remains
unpaid, Borrower and any material subsidiaries of Borrower (hereinafter referred
to as the  "Organization") are Year 2000 Compliant.  As used herein,  "Year 2000
Compliant"  shall  mean  that  all  software,   embedded  microchips  and  other
processing  capabilities  utilized by the Organization or the Organization's key
suppliers,  vendors  and  customers  the  failure of which would have a material
adverse effect on the Organization or the key supplier, vendor or customer, will
correctly process, sequence, and calculate,  without interruption,  all date and
date related data for all dates to, through and after January 1, 2000, including
leap year calculations,  and shall recognize,  store and transmit date data in a
format which clearly  indicates the correct  century.  Borrower shall deliver to
Lender, upon Lender's reasonable request, all periodic internally and externally
prepared  evaluations and progress reports  concerning the  Organization's  Year
2000 plan and Year 2000 readiness and such other information,  documentation and
materials as Lender may reasonably request from time to time in order to confirm
that the  Organization  is Year 2000  Compliant  and the  method(s)  used by the
Organization to become Year 2000 Compliant.
