ITEM 1.     BUSINESS

                                   THE COMPANY

     Exigent International,  Inc. (together with its subsidiaries,  "Exigent" or
the  "Company")  is a holding  company  formed in 1996 to capitalize on emerging
high-technology opportunities.


     The Exigent Family of Companies:

                         Exigent International, Inc.

            [--------------------------------------------------]

    Software Technology, Inc.                            FotoTag, Inc.

     Exigent was formed on March 25, 1996 by Software  Technology,  Inc. ("STI")
to acquire  and hold all of the assets and the issued and  outstanding  stock of
STI. On January 30, 1997, Exigent acquired all of the issued and outstanding STI
stock in exchange for 3,486,600  Exigent Common Shares and 697,320 Exigent Class
A Preferred  Shares.  Exigent also issued  645,270  Warrants in exchange for STI
warrants held by STI shareholders and Joseph Walker & Sons, Inc. ("JWSI").  Upon
the completion of the exchange, STI became a wholly owned subsidiary of Exigent.

     As  reflected in the chart above,  Exigent has two  wholly-owned  operating
subsidiaries,  STI and  FotoTag,  Inc.  ("FTI").  Formed in 1978,  STI  provides
systems and software  engineering services to a range of industry and government
clients.  STI  specializes in software  solutions for the command and control of
spacecraft.  FTI  (formed in 1997)  developed  and  markets  internationally  an
advanced  passenger/baggage  reconciliation  system,  FotoTag(R)1,  for  use  by
airports and airlines.

     Typical  customers for the products and services of Exigent's  subsidiaries
are:

          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,  that
               provide cellular telephone services.

          o    Commercial  and  government  customers  that require 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.   o
               Engineering  firms that require  software  design and development
               services.

          o    Foreign agencies that control airports and airport security.

          o    Foreign and domestic airlines.

                              PRODUCTS AND SERVICES

SYSTEM ENGINEERING AND RELATED SERVICES

     The Company offers a wide range of custom software  applications  and other
software engineering services. The Company provides advanced technical solutions
for defense,  government,  and industry,  including  advanced  embedded software
products.

<PAGE>
     Company  personnel,  working at Company  facilities or at customer's sites,
develop   operational   systems  for  government   and  commercial   space-based
applications.  These  include  ground  station  support,  test  and  integration
systems,  mission  tasking  systems,  operational  simulators,   launch  support
systems,   and  data  analysis  and  MIS  centers.  The  Company  also  provides
space-based flight systems and simulators.

     In addition to developing and providing the  general-purpose and customized
engineering solutions described in the previous paragraph,  the Company provides
engineering support to the users of OS/COMETTM2 products.

     The Company has signed a strategic  agreement to provide software solutions
to a major vendor of fast-food  systems.  Under this agreement,  Exigent has the
right to participate in the  development of future  improvements  to the system.
This initiative  reflects the Company's goal to leverage its core technology and
skills to expand to other markets.

SOFTWARE PRODUCTS

     The  OS/COMET  suite of command and  control  software  products  forms the
Company's  flagship software offering.  Originally  developed for the support of
satellite  ground  stations and for  spacecraft  integration  and testing,  this
software  suite has evolved into a  general-purpose  integrated  tool set.  This
"Commercial-Off-The-Shelf"   ("COTS")  program  provides  a  real-time  command,
control,  and  data  acquisition   environment  for  government  and  commercial
solutions.  Because  of the  flexibility  of its  design  and its  architecture,
OS/COMET  products can be adapted to many  complex  control  situations,  on the
ground  or  in  space.   OS/COMET  executes  on  any  of  several   inexpensive,
POSIX-compliant  UNIX(TM)3 workstations and makes extensive use of the "X Window
System(TM)"4 and the "OSF/Motif(TM)"5 graphical user environment standards.

     OS/COMET is the heart of the satellite  control system for  "IRIDIUM(R)"6 ,
the global  wireless  communication  system built by a world-wide  consortium of
investors to provide the elusive  "world-wide  dial tone".  IRIDIUM offers local
calling,  data  transmission  and  paging,  anywhere  on  the  planet.  It  is a
constellation  of 66 Low Earth  Orbit  ("LEO")  satellites  (plus  six  on-orbit
spares).

     As a result of the use of  OS/COMET  in the  IRIDIUM  and  other  programs,
Exigent  was  selected  by prime  contractor  Motorola,  Inc.  as the  preferred
supplier  of command  and  control  software  for the  Celestri(TM)7  and future
communication  systems.  Celestri,  a mix of LEO and  Geostationary  Earth Orbit
("GEO")  broadband  satellites in a hybrid  constellation  of about 70 units, is
planned to be operational in 2003.

     STI was also  selected  to upgrade  the  ground  station  software  for the
NAVSTAR  Global  Positioning  System  ("GPS").  A U.S.  Air Force  project,  the
24-satellite  GPS  constellation  provides  precise  and  continuous  world-wide
all-weather  positioning,  navigation data and nuclear detonation detection. The
entire constellation is under OS/COMET command and control.  GPS's 24 satellites
provide worldwide navigation data for military and civilian aircraft, spacecraft
and  land  and  marine   applications.   The  new   system   replaces  a  slower
mainframe-based  system with antiquated "legacy" software that is now too costly
to maintain.

     FotoTag is an innovative airport  passenger/baggage  reconciliation system,
developed  in  response  to the  needs  of  international  airport  and  airline
operations.  It is expected to provide enhanced  departure  control  facilities,
improve passenger  servicing,  and reduce airline and airport  management costs.
The  system  uses   IATA-standard   barcode   technology  coupled  with  digital
photography.  FotoTag can interface with currently existing airline networks and
Customer  Reservation Systems ("CRSs").  Exigent expects its FotoTag products to
begin  generating  revenues in the Company's next fiscal year as its airline and
airport passenger/baggage reconciliation system becomes operational.

PRODUCT DEVELOPMENT

     The Company is developing the Active Tracking  Engine(TM)8 ("ATE"), an open
architecture,  middleware  product  for  horizontal  market  applications.  This
object-oriented "network facilitator" enables message-oriented data distribution
in collaborative  computing  environments.  It employs a "publish and subscribe"
information   management  method  that  efficiently  uses  available  bandwidth.
Application-independent  ATE is  being  developed  to  run  under  the  "Windows
95/NT"(R)9 operating system, and can be readily integrated with other platforms.

     The  Company  expects  to market  ATE as a  stand-alone  product  to system
integrators   and  application   developers.   ATE  is  expected  to  provide  a
communication and integration core for a whole family of related products.

     FTI is developing  plans to integrate  ATE in the FotoTag  product to route
messages between distributed servers and workstations in the local installation,
or between any networked  equipment at widely separated  airports.  ATE is being
readied for testing and delivery in the third quarter of 1998.

     The Company plans to develop and offer the  Integrated  Control  Center(TM)
10("ICC"),  a complete  mission control solution based on the OS/COMET family of
products,  but with  added  functionality  provided  by the ATE and  specialized
product  development.  The ICC is expected to deliver a turnkey  ground  station
solution  including  mission  planning,  mission support,  orbit maintenance and
decision-making  capabilities,  all  within  the  context  of a  Graphical  User
Interface.  The  Company  anticipates  that it will find  strategic  partners to
provide certain products to be integrated into the ICC structure.

RESEARCH AND DEVELOPMENT

     Exigent continues to conduct research and development for specific projects
or tasks under contract to customers in government and industry.  The Company is
also now pursuing  diversification into the commercial products business with an
array of  internally  developed  products  planned.  The  Company  funds R&D for
development  or enhancement of certain  products which  management  believes are
commercially marketable.  Generally,  most of the Company's  contract-funded R&D
relates to satellite command and control,  developing systems for the ground and
space  segments  of  the  aerospace/defense   industry,  and  telephone  systems
providers in the telecommunications  industry.  Through these projects,  Exigent
often  identifies   potential  software  product  offerings  for  commonly  used
functions.  These  concepts are  evaluated  and,  based on  estimated  costs and
commercial  sales  potential,  funded and  developed  by the Company as separate
products. The emphasis placed on low cost solutions by customers drives the need
for reusable software components and products.

     Exigent expensed against earnings  $47,854,  $239,986,  and $154,856 in its
fiscal years ended January 31, 1998, 1997 and 1996, respectively,  on internally
sponsored  research  and  development.  These  expenditures  were  made  for the
evaluation of new products and  technologies to expand and enhance the Company's
products and services.

     In addition  to these  expensed  funds,  the  Company  continues  to invest
significantly  in  product  development.  With  respect  to  commercial  product
development,  the Company has capitalized $1,149,685,  $556,167, and $161,785 in
its fiscal years ended  January 31,  1998,  1997 and 1996,  respectively.  These
amounts include  investments  allocated to FotoTag and to the OS/COMET family of
products.  Exigent  continues its commitment to these  products with  sustaining
engineering expenditures in excess of $2,000,000 against earnings for its fiscal
year ended January 31, 1998.

     Of Exigent's  major sites of operation,  the majority are available for R&D
activity.  Details  of the  various  Exigent  locations  can be found  under the
heading  "Properties".  Each  facility has extensive  computer  resources and is
networked to each of the other facilities.

                               MARKETING AND SALES

MARKETING

     The Company distributes its products and services and licenses its products
(a) indirectly through VARs, and (b) directly to end users.

     Many  of  the  Company's  opportunities  to bid on  contracts  for  systems
development,  software engineering,  or support are derived through solicitation
of,  or  by  initiation  from,   existing  customers  and  through  direct  mail
solicitation.   The   Company   also  uses  leads   generated   by   print-media
advertisements,  Internet inquiries,  round-table forums,  speaking engagements,
trade shows, and specialized publications such as the "Commerce Business Daily".
Exigent's  solicitation  efforts are supported by a number of in-house  business
development  representatives,  periodically  augmented by ad hoc technical teams
recruited  internally from the Company's  engineering staff to pursue individual
contract initiatives.

     Prospects  for the  Company's  present and future  commercial  products are
usually generated through similar means.  Exigent regularly advertises in "Space
News Magazine", "Via Satellite" and "Aviation Week", and participates in various
trade shows, including the recent "Satellite98 Conference".

     Exigent has recently used its new demonstration and multi-media facility to
showcase products and services to a number of potential customers.  Through this
and the other related and coordinated  marketing  efforts mentioned above and an
expansion of the Company's  presence on the World-Wide Web, the Company hopes to
increase  product  sales as a  percentage  of total  revenue  while also growing
revenues from services.

REVENUE SOURCES

     The Company's  revenues are dependent on three significant  customers,  the
Naval Research  Laboratory  ("NRL"),  Motorola,  Inc.  ("Motorola") and Lockheed
Martin Corporation ("Lockheed"), the loss of any one or more of which would have
a material adverse effect on the Company's business,  results of operations, and
financial  condition.  Aggregate sales to each of NRL,  Lockheed and Motorola in
the  Company's  fiscal year ended  January 31, 1998 were in excess of 10% of the
Company's  consolidated  revenues.  The loss of NRL,  Motorola  or Lockheed as a
customer  would  have  a  material   adverse  effect  on  the  Company  and  its
subsidiaries taken as a whole.

     The  government  contracts  to which the  Company is a party are subject to
termination at the election of the government entity party thereto.

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

CONTRACTS

     Generally,  the  government  contracts  specify  goals  to be  reached  and
estimate the number of hours of work of various levels of employees  required to
reach the goals. The contract price is based on  pre-approved,  hourly rates for
employees' time with certain pre-approved  overhead costs included. If the goals
are met in fewer hours,  the contract  value is reduced.  If it takes more hours
than  estimated to meet goals,  the resulting fee percentage is reduced on a pro
rata  basis  based on cost of actual  hours  delivered  versus the cost of hours
estimated in the contract.

     Most of the Company's  commercial contracts are "firm fixed price" or "time
and material" agreements. These agreements generally call for a specified set of
requirements to be delivered at a negotiated  price. With respect to fixed price
agreements,  if development  costs yield a result that is less than the estimate
for the fixed price, the Company will make a greater profit on that contract. If
development  costs exceed the estimated  effort for the fixed price, the Company
will have less profit on that  contract.  These types of contracts are typically
broken  down  into a set of  milestones  with  progress  payments  made  at each
milestone.  These are generally  called earned value  milestones and are used to
benchmark  progress,  help the customer track status, and provide trigger points
for payments.

     STI has several  contracts  with the NRL.  Its largest  contract  with NRL,
which  relates to space  systems  applications  and  operations,  was renewed in
January 1995. It provides for services to be initially  performed  over two base
years with three one-year  options,  with a total  estimated cost of $25,186,826
and a fixed fee of $1,896,362.  As of January 31, 1998,  these three options had
been  exercised  and STI had received cost payments and fees in the aggregate of
$23,691,856  under the contract.  The contract  with  Lockheed  relates to a GPS
project with the U.S. Air Force.  It began in August 1995 and continues  through
September 30, 2000 unless modified by Lockheed.  STI received  $3,914,692  under
this contract for the Company's fiscal year ended January 31, 1998 with a funded
backlog at that time of approximately $806,847.

     STI has  various  contracts  with  Motorola,  some of which are fixed price
contracts  and  some of  which  are time  and  material  contracts.  Most of the
revenues from  Motorola in the past four years were received  under an agreement
executed  in  February  1994 under  which STI agreed to  provide  Motorola  with
satellite  and ground  control  software for the system  control  segment of the
IRIDIUM  communications  system.  STI  expects  to  receive  payments  under the
contract  for several  more  years.  As of January 31,  1998,  STI had  received
approximately  $41,886,144  from Motorola  under this and other  contracts.  The
backlog as of January 31, 1998 for Motorola was $1,577,223.

            STI also receives  revenues from Allied  Signal  Technical  Services
Corporation   ("Allied")  under  various   purchase  orders.   It  has  received
approximately $492,633 from Allied during the fiscal year ended January 31, 1998
and approximately $1,041,536 in backlog remains under existing purchase orders.

            Based on the development plans and schedule to incorporate  customer
features  and  functionality,  there were no  revenues  generated  by FTI in the
Company's  fiscal  year ended  January  31,  1998.  Exigent  expects its FotoTag
products to begin generating  revenues in the Company's next fiscal year, as its
airline and airport passenger/baggage reconciliation system becomes operational.
ATE is being readied for testing and delivery in the third  calendar  quarter of
1998.

                                     BACKLOG

     STI estimates that its backlog orders believed to be firm as of January 31,
1998 and 1997 were  $11,334,085  and  $31,571,380,  respectively.  Approximately
$5,101,154  of the backlog in the  Company's  fiscal year ended January 31, 1998
relates to the unfunded portion of government  contracts.  The Company estimates
that  approximately  85% of its backlog on January  31,  1998 will be  completed
before December 31, 1998.  This does not include  potential  additional  revenue
anticipated from this and other new contracts.

                                   COMPETITION

     Exigent  believes it is best known  (through  its  subsidiary  STI) for the
development  of  advanced  command  and  control  technology  for  communication
satellite  systems.  In general,  aerospace/defense  contractors  must obtain or
produce this type of software in  connection  with the  manufacture  and sale of
satellites,  but they often contract with other companies,  such as Exigent,  to
provide the software.

     Exigent   (through  its  subsidiary   STI)  has  two  competitors  who  are
"independent"  providers of command and control systems and software.  There are
few "independent" competitors because of the depth of expertise involved and the
high cost of failure. STI is the largest of this group.

     Exigent   competes   directly  and  indirectly   with  many  of  the  large
aerospace/defense  contractors,  which are also often its  customers.  Companies
within  the  professional  services  sector of the  computer  industry  are also
potential  competitors.  Some professional  computer services  companies service
satellite  ground  stations  with  information  technologies  such as systems to
organize,  archive,  interpret  and analyze  telemetered  data.  These and other
computer  companies  also may  compete in a limited  way with some of  Exigent's
products and services.

     In  addition  to the  independent  competitors,  there  are  seven  leading
aerospace   and/or  defense   contractors  in  the  United  States  that  derive
substantial revenues from space-related sales and who have substantially greater
capital and other resources than Exigent.  Most of them have developed tracking,
telemetry,  and command and control  software  in-house as primary  contractors,
through  sub-contractors  and  through  outsourcing.  Income  derived  from  the
development of such software  represents only a small portion of the revenues of
these companies,  but the software is nevertheless  essential to their contracts
to manufacture satellites.

     FTI builds on the Company's  tracking control  expertise to compete against
the three major systems (developed  outside the USA) that represent  competition
in the airline passenger/baggage reconciliation market.

                        PATENTS, TRADEMARKS, AND LICENSES

     Exigent  received a trademark  registration on the "FotoTag"  product name.
The Company  believes that OS/COMET will also be accorded  registered  status in
the near future.

     Three  provisional  patent  applications  were  filed  in  1997,  including
applications  covering the ATE, and for a software  architecture for a satellite

NAME                             POSITION WITH REGISTRANT

 Bernard R. Smedley               Chairman of the Board, CEO, President, COO,
                                    and Director
 Don F. Riordan, Jr. (1)          Executive Vice-President, Treasurer, CFO,

 William K. Presley               Executive Vice-President, Chief Technology
                                    Officer, and Director

(1)  Mr.  Riordan is the Trustee of the  Company's  three  qualified  retirement
     plans, including its Employee Stock Ownership Plan (the "ESOP").

     Bernard R.  Smedley,  age 61,  became a director  of Exigent on February 7,

     Don F.  Riordan,  Jr.,  age 51, has been a Director of STI since 1980,  and
Secretary/Treasurer  and Chief  Financial  Officer since 1991 as well as holding
the offices of Chairman of the Board, Vice President, Secretary and Treasurer at
various times prior to 1991. Mr. Riordan is currently a Director, Treasurer, and
Chief Financial Officer of Exigent, and is a Director,  and  Secretary/Treasurer
of both STI and FTI.

     William K. Presley, age 51, has been a Director of STI since 1987, Chairman
of the Board until 1997 and Vice President (or President in 1990) since 1987. He
is  currently  serving  as a  Director,  Executive  Vice  President,  and  Chief
Technology  Officer of Exigent.  He has been  employed by the Company since July
1983 as a chief systems engineer.

ITEM 2.     PROPERTIES

     Exigent's corporate  headquarters are located in Melbourne,  Florida on the
"Space  Coast",  near NASA's  Kennedy  Space  Center.  The Company,  through its
subsidiary STI,  currently leases a 29,000 square foot building under a ten-year
lease, which will expire on December 1, 2005. Exigent has the right to renew the
lease for two  additional  five-year  terms,  and has an option to purchase  the
property that may be exercised during certain periods prior to the expiration of
the fifth and tenth years of the lease.  The  purchase  price is the fair market
value of the property  determined  by  appraisal,  but in no event less than the
outstanding balance on the mortgage.

     In  February  1998,  Exigent,  through  its  subsidiary  STI,  occupied  an
additional leased building of approximately 30,000 square feet, located adjacent
to  its  existing   facility.   This  building  houses  the  Exigent   corporate
headquarters,  including the executive, administrative, and marketing staff, FTI
and the  Product  Development  department.  The lease is for a  ten-year  period
expiring in April 2007.

     In addition to the corporate headquarters,  Exigent, through its subsidiary
STI, leases the following space at other sites. Lease expiration dates are shown
parenthetically:

          o    Alexandria,  Virginia - approximately  15,296 square feet (August
               31,  1998);  Exigent  has the right to renew this lease for up to
               two additional one-year terms.

          o    Aurora,  Colorado - approximately  2,494 square feet (October 31,
               1999).

          o    Colorado  Springs,  Colorado -  approximately  1,946  square feet
               (July 1, 2000).

          o    La Plata, Maryland - approximately 1,935 square feet (October 14,
               1998);  Exigent has the right to renew this lease for up to three
               additional one-year terms.
          
          o    Mesa,  Arizona -  approximately  2,971 square feet  (November 20,
               1999).

     Management  believes  that with the new addition to its  headquarters,  its
occupancy  needs will be met through the Company's  next fiscal year. Due to the
nature of the Company's business,  there are no special facility requirements to
consider,  given that software  development  can be conducted in standard office
space and its  manufacturing  requirements  are minimal  and most often  handled
through outsourcing.

ITEM 3.     LEGAL PROCEEDINGS

     There are no material  pending  legal  proceedings  to which Exigent or its
subsidiaries  or their  properties are a party or were a party during the fourth
quarter of the Company's fiscal year ended January 31, 1998.

ITEM 4.     SUBMISSION OF MATTERS TO VOTE OF SECURITY HOLDERS

     No matters were  submitted to a vote of security  holders of Exigent during
the fourth quarter of the Company's fiscal year ended January 31, 1998.

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

LIQUIDITY

     As of January 31, 1998 and 1997,  the Company's  ratio of current assets to
current liabilities was 1.9 and 2.0,  respectively.  As of January 31, 1998, the
Company's  quick liquidity ratio was 1.8, up from 1.7 for the year ended January
31,  1997.  This  increase  is due to the  increase  in  product  sales over the
Company's fiscal year ended January 31, 1997.

     The  Company's  cash  portfolio  (cash  and  cash  equivalents)   increased
$3,211,803  at January  31,  1998.  This  increase  is due to cash  provided  by
operating  activities of $5,239,810 and cash provided by financing activities of
$413,759 less cash in the amount of $2,441,766 used in investing activities. The
cash provided by operating  activities increased primarily due to an increase in
cash paid by  customers.  This increase is the result of the increase in product
sales during the Company's  fiscal year ended  January 31, 1998. By  comparison,
the  Company's  cash  portfolio  increased  $158,621 at January 31,  1997.  This
increase was due to cash provided by operating activities of $1,679,983 and cash
provided  by  financing  activities  of  $428,366  less  cash in the  amount  of
$1,949,728  used  in  investing  activities.  The  cash  provided  by  operating
activities  increased  primarily  due  to an  increase  in  cash  received  from
customers.

     In the  Company's  fiscal  years ended  January 31, 1998 and 1997,  Exigent
acquired  $1,306,693 and  $1,382,163,  respectively,  of capital assets compared
with  $1,122,226 in 1995.  This  expenditure in the Company's  fiscal year ended
January 31, 1998 was due primarily to an investment made in computing  resources
to support the  demonstration  of the Company's  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 Company's
fiscal  year ended  January  31,  1998,  the  Company  made a decision  to lease
resources  for office  computing  needs.  Capital  for  equipment  purchases  is
expected to remain  stable for the next two fiscal  years as the Company has now
modernized,   and  has  acquired  computer   resources  for  expected  near-term
operations. The Company will continue its policy of leasing resources for office
computing needs.

     In the Company's  fiscal years ended January 31, 1998 and 1997, the Company
also spent $1,149,685 and $556,167,  respectively,  in capitalized  research and
development costs to develop new products considered  essential in maintaining a
strong market position in the Satellite  Command and Control Industry as well as
the airport  security  industry.  There was $161,785 of research and development
costs capitalized in fiscal 1995. In the Company's fiscal year ended January 31,
1998,  it  was  determined  that  the   capitalized   research  and  development
expenditures  related to the OS/COMET product incurred prior to such fiscal year
should be expensed  due to a change in  estimated  revenue and  therefore  these
costs were taken against the current fiscal year earnings.

     In addition,  management reviewed the status of the ICC development project
which  had been  accomplished  to date and  determined  that the  asset was more
appropriately classified as property, plant, and equipment, as it was being used
as  demonstration  equipment  during the Company's fiscal year ended January 31,
1998. The first year  depreciation  (20%) was taken against the Company's fiscal
year  ended  January  31,  1998  earnings.  Both of these  management  decisions
resulted in an adjustment in earnings per share from $0.33 to $0.29.

     Cash provided by financing  activities for the Company's  fiscal year ended
January 31,  1998 was  $413,759.  This was  comprised  of  $800,000  borrowed to
purchase  computer  equipment  for product  developments,  offset by $382,108 in
principal  payments on  long-term  debt.  In  addition,  $177,867 of capital was
raised  through  the  exercise  of stock  options  and  warrants.  Cash  used in
financing  activities  for the Company's  fiscal year ended January 31, 1998 was
$428,366.

     In the Company's  fiscal year ended January 31, 1998 the Board of Directors
determined  not to pay any  dividends,  but  instead to use its cash for product
development and operations.  As a private company, the Company paid dividends of
$0.45  and  $0.30  ($.075  and  $.050,  giving  retroactive  effect of the stock
exchange)  per share in the  Company's  fiscal years ended  January 31, 1997 and
1996, respectively, for total dividends of $309,549 and $177,955, respectively.

     Principal  payments on long-term  debt  amounted to $382,108,  $251,335 and
$6,363 in the  Company's  fiscal years ended January 31, 1998,  1997,  and 1996,
respectively. As of January 31, 1998 and 1997, Exigent had a line of credit with
a bank of  $1,800,000.  Draws  against  the line as of January 31, 1998 and 1997
were  $0  and  $182,000,  respectively.  All  accounts  receivable,   equipment,
furniture, and fixtures of STI are pledged as collateral on the line of credit.

     Management  believes  that  capital in addition to that  available  through
operations  and the  available  line of  credit  will be  necessary  to fund the
Company's  plans for expansion and growth during the Company's  next fiscal year
and the growth plans for such fiscal year and beyond.  The Company may seek debt
or equity  financings.  However,  there can be no assurance  that such financing
will be available on acceptable terms, if at all.

PROVISION FOR INCOME TAXES

     The effective rate for the Company's fiscal year ended January 31, 1998 was
38.2%, up 82.7% from the Company's  fiscal year ended January 31, 1997 effective
rate of negative 44.5%. This increase is the result of the public offering costs
incurred  during the Company's  fiscal year ended January 31, 1997 that were not
deductible  for  federal  and state  taxes.  The Notes to  Financial  Statements
describe the  differences  between the U.S.  statutory and effective  income tax
rates.

ANALYSIS OF OPERATIONS

OVERVIEW

     The Company  has  changed  the last day of its fiscal year to December  31.
Hence,  the  Company's  next fiscal year,  which will be an eleven month period,
will end on December 31, 1998.

The current  contract  base  provides  sufficient  backlog to maintain  the
Company  through  the first  four to six  months of its next  fiscal  year.  The
backlog as of January 31,  1998 for  commercial  and  government  contracts  was
$1,626,606  and  $9,707,479,  respectively.  The  Company  invested in excess of
$3,000,000  over the  last two  years in its  software  product  OS/COMET.  This
investment  facilitated the significant contract awards that management believes
would have been  impossible  otherwise.  Commitment to maintain  support for the
product will continue through the Company's next fiscal year and is necessary to
deliver the services under contract.

     The Company  completed  development of a new commercial  software  product,
FotoTag,  during its fiscal year ended  January  31,  1998.  Management  expects
revenue to begin on sales of this product in its next fiscal year.

     The Company  completed  expansion of its corporate  headquarters in January
1998.  The  commercial  satellite  business is projected to continue with strong
sales worldwide and is expected to show moderate increases throughout the end of
the decade, providing additional opportunities for the Company.

     Demand  for  software   engineers  is  expected  to  provide  new  customer
opportunities for the Company, but will place a premium on efforts to retain the
current  workforce.  This risk will put additional  pressure on overall  payroll
costs, but should be an industry-wide  phenomenon.  Management believes that the
benefits  offered by the Company remain above the level of its  competition  and
should help to stabilize  its  workforce.  Overhead  costs for  benefits  should
remain flat and the Company expects to maintain the same percentage of wages for
the Company's  next fiscal year.  Management  believes it is important  that the
Company not reduce  benefits  while the demand for  software  engineers  remains
high.  To do so and hold costs stable has been a management  challenge  and will
continue to be so in the near future.  Maintaining  the Company's  comprehensive
benefit plan will also facilitate its ability to sustain an effective recruiting

</TABLE>


     These sales  reflect a 65% to 35%  government  to  commercial  split in the
Company's  fiscal year ended  January 31, 1998 compared to a 61% to 39% split in
the  Company's  fiscal year ended January 31, 1997 and a 51% to 49% split in the
Company's  fiscal  year ended  January 31,  1996.  Government  contract  revenue
increased in the Company's fiscal year ended January 31, 1998 due to the Company
obtaining  additional work with Lockheed on the GPS contract as well as the sale
of OS/COMET  licenses for use on the GPS contract.  The  Company's  sales in its
fiscal year ended January 31, 1997  increased  from its sales in its fiscal year
ended January 31, 1996 due largely to obtaining the Lockheed contract as well as
additional work on NRL contracts.

     Gross profit increased  significantly  from $5,246,847  (17.5% of sales) to
$9,326,933  (26.1% of sales)  for the years  ended  January  31,  1997 and 1998,
respectively,  primarily due to the Company's increase in product sales over the
previous fiscal year and a decrease in labor costs on programs.  Gross profit as
a percent of sales for the  Company's  fiscal  year ended  January  31, 1996 was
fairly  consistent  with the  Company's  fiscal  year ended  January 31, 1998 at
$5,883,499 (23.3% of sales).

</TABLE>

     General  and  administrative  expenses in the  Company's  fiscal year ended
January 31, 1998 were $7,050,070,  32% or $1,705,859 higher than its fiscal year
ended January 31, 1997 expenses of $5,344,211.  This increase resulted primarily
from $706,139 in administrative labor costs due to the addition of new employees
required to  administer a public  company and to expand the business base of the
company,  $290,151 in additional  costs related to marketing and  recruiting and
$425,000 in severance costs  associated with the unplanned  departure of several
senior level  employees.  General and  administrative  expenses in the Company's
fiscal year ended January 31, 1997 were  $5,344,211,  39% or  $1,503,542  higher
than its expenses of $3,840,669 in its fiscal year ended January 31, 1996.  This
increase resulted  primarily from $1,058,951 in public offering costs,  $364,155
in  additional  costs  related to  marketing  and  recruiting,  and  $387,442 in
administrative  costs due to the hiring of more  employees  during the Company's
fiscal year ended January 31, 1997.

     Net income  increased  significantly  to $1,345,429  (3.8% of sales) in the
Company's fiscal year ended January 31, 1998. Management attributes the increase
to the  increased  OS/COMET  product  sales  from 1.5% of total  revenue  in the
Company's  fiscal year ended  January 31, 1997 to 5.6% in the  Company's  fiscal
year ended January 31, 1998. As was  mentioned  previously in the  discussion on
capitalized research and development,  the decisions to take a more conservative
position on both the  integrated  control  center  asset and the OS/COMET in the
Company's fiscal year ended January 31, 1997 and prior expenditures had a fairly
significant  impact  on the  current  year  earnings.  The  net  income  for the
Company's fiscal year ended January 31, 1998 was decreased for these two actions
by approximately $225,000 or $0.04 per share. Net income dropped from $1,131,741
(4.5% of sales) in the  Company's  fiscal  year ended  January 31, 1996 to a net
loss of $486,238 (1.6% of sales) in the Company's  fiscal year ended January 31,
1997.  Management  attributes this decrease to the  approximately  $1,000,000 of
costs incurred for the public  offering  during the Company's  fiscal year ended
January 31, 1997.

FAS 130 AND 131 DISCLOSURE

     The two new financial Accounting Standards,  130 - Reporting  Comprehensive
Income  and 131 -  Disclosures  about  Segments  of an  Enterprise  and  Related
Information, will not be effective until the Company's next fiscal year. At that
time if there is an impact, the statements will be adjusted  accordingly.  There
appears to be no impact to the  statments as a result of these new standards for
the Company's fiscal year ended January 31, 1998.

YEAR 2000 ISSUES

     Some existing  computer programs will be unable to recognize dates properly
in the Year 2000 ("Y2K") and beyond.  During 1997, Exigent conducted an informal
study  of  its  products,  systems  and  operations,   including  systems  under
development,  to  improve  business  functionality,  to  identify  those  of its
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,  Exigent  recognized that the
OS/COMET  product  required  certain  modifications  to be Y2K compliant.  Those
modifications  have been made to the software  and are  available in the current
release,  Version 3.5.  Exigent has also initiated  communications  with certain
third parties whose computer systems'  functionality  could adversely impact the
Company. These communications will facilitate  coordination of any necessary Y2K
conversions  and will,  additionally,  permit Exigent to determine the extent to
which the Company may be  vulnerable  to the failure of third parties to address
their own Y2K issues.

     The costs of Exigent's  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  Exigent's  overall  results of
operations or cash flows.

     The  assessment of the costs of Exigent's Y2K  compliance  effort,  and the
timetable for the Company's planned completion of its own Y2K modifications, are
management's   best   estimates.   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 the Company's planned schedule. There
can be no guarantee that these estimates will prove accurate, and actual results
could differ from those estimated if these assumptions prove inaccurate.

     Based upon progress to date, however,  Exigent believes that it is unlikely
that the  foregoing  factors will cause actual  results to differ  significantly
from those estimated.  As to the systems of the third parties that are linked to
Exigent's, there can be no guarantee that those of such systems that are not now
Y2K-compliant will be timely converted to compliance. Additionally, there can be
no  guarantee  that  third  parties  of  business  importance  to  Exigent  will
successfully  and  timely  reprogram  or  replace,  and  test,  all of their own
computer hardware, software and process control systems.

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  Factors  Relating  to
Forward-Looking Statements" below.

     DIVERSIFICATION  AND LONG TERM GROWTH. The Company expects to diversify its
business by developing  additional COTS products for sale in both commercial and
government  markets.  The Company currently plans to seek opportunities for long
term  growth  through  acquisitions,  development  of  products  for  commercial
applications, and leveraging the Company's existing technologies and products.

     PRODUCT   DEVELOPMENT.   As  described   above  (see  "Business  -  Product
Development"  and  "Business  -  Research  and  Development"),  the  Company  is
developing  new products and product  offerings,  including the ATE and the ICC.
The Company plans to investigate other new product development  opportunities as
part of its effort to expand its product offerings and market.

OTHER FORWARD-LOOKING STATEMENTS

     Statements  contained in this Form 10-K that are not  historical  facts are
forward-looking  statements  made pursuant to the safe harbor  provisions of the
Private  Securities  Litigation  Reform Act of 1995. In addition,  words such as
"believes,"  "anticipates,"  "expects" and similar  expressions  are intended to
identify  forward-looking  statements.  Such forward-looking  statements involve
known and unknown  risks,  uncertainties,  and other factors which may cause the
actual results,  performance or achievements of the Company or events, or timing
of events, relating to the Company to differ materially from any future results,
performance  or  achievements  of the  Company or  events,  or timing of events,
relating to the Company expressed or implied by such forward-looking statements.
The Company  cannot assure that it will be able to anticipate or respond  timely
to changes which could  adversely  affect its  operating  results in one or more
fiscal  quarters.  Results  of  operations  in any  past  period  should  not be
considered indicative of results to be expected in future periods.  Fluctuations
in operating  results may result in  fluctuations  in the price of the Company's
common stock.

     The more prominent known risks and uncertainties  inherent in the Company's
business  are set forth  below.  However,  this  section  does not  discuss  all
possible risks and uncertainties to which the Company is subject,  nor can it be
assumed  that  there are not other  risks  and  uncertainties  which may be more
significant to the Company.

     Such other  factors  include,  among  others,  those  described  in Item 1.
"Business," and this Item 7. "Management's  Discussion and Analysis of Financial
Condition and Results of Operation " and the following:


          continued  dependence on a small number of  significant  customers for
          substantially  all of the Company's  revenue and the potential loss of
          one or more of the Company's principal customers;

          continued  dependence on government agencies for a significant portion
          of the Company's revenue;

          the shortage of qualified  and  competent  software  engineers and the
          risk that the Company will be unable to retain its key  employees  and
          managers,  especially  in the  event  the  Company  loses  one or more
          contracts or principal customers;

          dependence  on the  satellite  command  and control  industry  and the
          potential  failure to  diversify  the  Company's  product  and service
          offerings and to expand its markets for commercial applications;

          the unanticipated  expense of new product  development,  the potential
          failure by the Company to develop new products under  development  and
          others  to be  developed  in the  future  successfully  or on a timely
          basis, and the failure of such products to achieve  substantial market
          acceptance;

          the  potential  loss of  customers  or  opportunities  because  of the
          Company's  relationship  as a  competitor  to  some  of its  principal
          customers;

          the  potential  loss of other  customer  opportunities  because of the
          Company's  subcontractor  relationship  with  Motorola  SatCom  on the
          IRIDIUM project;

          the possibility  that Motorola will elect not to move forward with the
          Celestri project,  or that Motorola may choose a vendor other than the
          Company; and

          the potential impact of increases in salary rates due to the amount of
          revenue related to services.

                          INDEPENDENT AUDITOR'S REPORT

Board of Directors and Stockholders
Exigent International, Inc.

We  have  audited  the  accompanying  consolidated  balance  sheets  of  Exigent
International,  Inc. (a Delaware corporation) and subsidiaries as of January 31,
1998 and 1997,  and the related  consolidated  statements of income,  changes in
stockholders'  equity, and cash flows for the years ended January 31, 1998, 1997
and 1996. These consolidated  financial statements are the responsibility of the
Company's  management.  Our  responsibility  is to  express  an opinion on these
consolidated financial statements based on our audits.

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

In our opinion, the consolidated  financial statements referred to above present
fairly,   in  all  material   respects,   the  financial   position  of  Exigent
International,  Inc. and  subsidiaries  as of January 31, 1998 and 1997, and the
results of its  operations  and its cash flows for the years  ended  January 31,
1998, 1997 and 1996 in conformity with generally accepted accounting principles.

stock with a cost of $4.25 per share  $(199,690) for accrued  bonuses and 38,600
shares of treasury stock with a cost of $4.25 per share  $(164,050) for the ESOP

were issued.

On May 29, 1996,  the Company  accrued a $260,285 bonus and issued 18,552 shares
of  treasury  stock  with a cost of $4.25  per share or  $78,846,  for bonus and
management  incentive  awards.  The Company's  stock was valued at $14.03 on the
date of the  issuance;  therefore,  the  difference  between  cost and market of
$181,439 was recorded as additional paid in capital.

On January 30, 1997, the following noncash transactions occurred:

The  Company  stockholders   exchanged  100%  of  Software  Technology,   Inc.'s
outstanding  common stock,  697,320  shares,  for 3,486,600  shares of Exigent's
common  stock and 697,320  shares of  Exigent's  Class A  preferred  stock which

The Company  retired  71,080  shares of treasury  stock with a cost of $4.25 per
share ($302,177). The remaining balance of $301,466, representing the difference
between the par value and cost of the treasury  stock issued,  was recorded as a
reduction of paid in capital.

The  Company  issued  300,000  shares of  Exigent  common  stock to  Monogenesis
Corporation in exchange for cash and services  performed related to the business
combination  (See  Note 1).  The  shares  had been  valued  at $2.25  per  share
($675,000)  by  independent  appraisal  for  purposes of  administration  of the
Company's employee stock ownership plan. The Company received $3,000 in cash and
expensed  services  which were  reflected  at a value of  $675,000.  The Company
reported an increase in the par value of its stock of $3,000 and additional paid
in capital of $675,000 as a result of the transaction.

                          NOTES TO FINANCIAL STATEMENTS
               FOR THE YEARS ENDED JANUARY 31, 1998, 1997 AND 1996


NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BUSINESS - Exigent International,  Inc. (Exigent),  a Delaware corporation,  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.  STI,  therefore,  became a wholly owned subsidiary of Exigent
and was the  consolidated  group's  (the  "Company")  only  source  of  business
operations  at January 30, 1997.  In March,  1997  FotoTag,  Inc.  (FotoTag) was
formed  as a wholly  owned  subsidiary  of  Exigent.  Exigent,  from the date of
formation  through  January 30, 1997,  had no material  activity  other than the
issuance of 300,000  shares of the Company's  stock for services  related to the
reorganization.

STI is a systems and software  engineering firm providing  innovative  technical
solutions  for  government  and industry  throughout  the U.S. STI also produces
OS/COMET - a commercially  available command and control development and support
system.  STI provides systems and software  engineering  services and commercial
off the shelf  products for real-time  command,  control,  and data  acquisition
systems.   STI  retains  expertise  in  leading  edge  technologies   supporting
applications  ranging from bit slice  microprocessor  software to large realtime
systems. STI specializes in command and control applications for ground, flight,
test, and process control and has extensive expertise in graphics,  simulations,
and information systems.

FotoTag 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.

Most recently, the FotoTag subsidiary designed Active Tracking Engine(TM) (ATE),
a new system platform for rapid  application  development of tracking objects in
global  domains.  This  subsidiary  has  positioned  ATE for  implementation  in
end-user  applications  as well as horizontal  marketing  middleware  for system
integrators.

POOLING OF  INTERESTS - On January 30, 1997  Exigent  acquired STI in a business
combination  accounted for as a pooling of interests.  STI became a wholly owned
subsidiary of the Company through the exchange of 3,486,600  shares of Exigent's
common stock and 697,320 shares of Exigent's  Class A preferred stock for all of
the outstanding stock and warrants of STI. The accompanying financial statements
for the year  ended  January  31,  1997 are  based  on the  assumption  that the
companies  were combined for the full year,  and  financial  statements of prior
years  have been  restated  to give  effect to the  combination.  There  were no
adjustments  to net assets or net income  during the fiscal  year as a result of
the entities combining.

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.

                          NOTES TO FINANCIAL STATEMENTS
               FOR THE YEARS ENDED JANUARY 31, 1998, 1997 AND 1996


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  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 because 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 United States  Government  procurement
practices  are included in contract  costs  because 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  is also  engaged  as a seller  of a number of  software  products.
Generally,  revenue is recognized upon delivery 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 performed.

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.

CONTRACT  AND OTHER  RECEIVABLES  - The  Company  considers  contract  and other
receivables  to be fully  collectible;  accordingly,  no allowance  for doubtful
accounts is required.

DEPRECIATION - 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.

               FOR THE YEARS ENDED JANUARY 31, 1998, 1997 AND 1996

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

AMORTIZATION  - The costs of  capitalized  research  and  development  costs are
amortized  over their  estimated  useful lives of three years.  Amortization  is
computed  on the  straight-line  method.  The  amortization  method  used is the
greater of the amount  computed  using (a) the ratio that current gross revenues
for a product bear to the total of current and anticipated future gross revenues
for that product or (b) the  straight-line  method over the remaining  estimated
economic life of the product.

INCOME TAXES - Income  taxes are  provided  for the tax effects of  transactions
reported in the  financial  statements  and consist of taxes  currently  due and
deferred taxes related  primarily to  differences  between the basis of vacation
and sick leave and research and  development  costs for financial and income tax
reporting.  The deferred  tax assets and  liabilities  represent  the future tax
return  consequences  of those  differences,  which  will  either be  taxable or
deductible when the assets and liabilities are recovered or settled.

SOFTWARE   DEVELOPMENT  COSTS  -  In  accordance  with  Statement  of  Financial
Accounting Standard 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  release,  and research and  development  performed as
contractual requirements are charged to operations.

BASIC AND DILUTED  EARNINGS  (LOSS) PER SHARE - During fiscal year ended January
31,  1998,  the  Company  adopted  the  provisions  of  Statement  of  Financial
Accounting  (SFAS) No. 128,  "Earnings per Share".  SFAS No. 128  superseded APB
Opinion  No.  15,   "Earnings  Per  Share",   and  specifies  the   computation,
presentation,  and disclosure  requirements  for earnings per share for entities
with publicly held common stock or potential common stock. It also requires that
prior period  earnings per share be restated to conform to the  requirements  of
SFAS No. 128.

Basic earnings  (loss) per share for the years ended January 31, 1998,  1997 and
1996 have been  computed by dividing net income  (loss) by the weighted  average
number of common shares  outstanding.  Diluted  earnings per share for the years
ended January 31, 1998 and 1997 have been computed by dividing net income by the
weighted  average number of common shares and dilutive  potential common shares,
outstanding.  Diluted  earnings  (loss) per share for the year ended January 31,
1996 is the same as basic  earnings  (loss)  per  share  because  there  were no
dilutive potential shares outstanding during this year.

DISCLOSURES  ABOUT FAIR VALUE OF FINANCIAL  INSTRUMENTS  - The  carrying  amount
reported  in  the  balance  sheet  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.

               FOR THE YEARS ENDED JANUARY 31, 1998, 1997 AND 1996

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS (CONTINUED) -
As of January 31, 1998 and 1997 the fair value of indebtedness  approximates its
carrying  value and was  determined  using market  interest  rates for debt with
similar maturities.

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.


NOTE 2 - ACCOUNTS RECEIVABLE

The following is a summary of accounts receivable:

NOTE 7 - CLASS A PREFERRED STOCK

Each share of Class A preferred  stock is convertible to a share of common stock
at the option of the holder.  Each share of Class A preferred stock participates
equally  with each share of common stock upon  declaration  of  dividends.  Upon
liquidation or dissolution,  the Class A preferred  stockholders are entitled to
receive  $2.50 per share prior to any  distribution  to holders of common shares
and Class B common shares.  The Class A preferred shares are not subject to call
or redemption.  The dividends of the Class A preferred stock are  noncumulative.
The issuance of the preferred  stock has been  reflected as a stock dividend and
is given retroactive  recognition in all earnings (loss) and dividends per share
disclosures.


NOTE 8 - STOCK WARRANTS

Common stock  warrants and related  exercise  prices have been  adjusted,  where
applicable,  to reflect  the  effects  of the  aforementioned  common  stock and
warrant exchange.

On March 20, 1996, STI sold 174,996 ten year capital stock purchase  warrants to
its  financial  advisors for one cent each to purchase  174,996  shares of STI's
capital stock,  for a fixed  exercise  price of $3 per share.  The warrants were
issued for services  rendered in connection  with the  registration  offer.  STI
determined the value of these warrants to be $17,497 and recorded this amount in
general and  administrative  expenses in fiscal year 1997. The exercise price of
the  warrants  was  greater  than their fair  market  value on the date  issued,
therefore they were deemed to be valued at the $17,497 purchase price.

On January 30, 1997, the Company  issued common stock  purchase  warrants in the
amount of 229,896,  to participants of the Software  Technology,  Inc.  Restated
Employee  Stock  Ownership  Plan and Trust;  240,378 to other  affiliates of the
Company  and  174,996 to a company  engaged as a  consultant.  In  addition,  on
January 30, 1997, the Company issued 425,000 warrants to Monogenesis Corporation
for $4,250 in cash.  Each  warrant  entitles the holder to purchase one share of
Exigent's  common stock at an exercise price of $3 per share. The terms of these
warrants provide that they may be exercised during the period beginning  January
30, 1997 and ending three years from that date.

     The  exercise  price of some of the  warrants  was greater  than their fair
market value at January 31, 1998.  These  warrants  were included in the diluted
earnings per share  calculation  at Note 19. The exercise  price of all warrants
was greater  than their fair market  value at January 31,  1997.  At January 31,
1998,  1,664 warrants were canceled.  Total warrants  outstanding at January 31,
1998 and 1997 were 1,064,754 and 1,070,270, respectively.

NOTE 9 - EMPLOYEE RETIREMENT PLANS

The Company has a defined  contribution  pension plan that covers  substantially
all  employees  who have met  certain  age and length of  service  requirements.
Contributions  to the plan were 10% of eligible  compensation for 1998 and 5% of
eligible  compensation  for 1997 and 1996.  Eligible  compensation for the years
ended January 31, 1998, 1997 and 1996 was approximately $13,810,000, $12,377,000
and  $10,958,000, respectively.  For the years ended January 31, 1998,  1997 and
1996,  the amount of pension  expense was  $1,381,023,  $618,838,  and $547,894,
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.
The  employer  contributions  made to the plan for the years  ended  January 31,
1998, 1997 and 1996 were $0, $618,838 and $547,894, respectively.


NOTE 10 - EMPLOYEE STOCK OWNERSHIP PLAN

The Company has an employee stock ownership plan (ESOP).  Contributions  to this
plan are at the  discretion of the Board of 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 $552,409, respectively, for the year ending January
31,  1998, $ -0- and  $247,535,  respectively,  for the year ending  January 31,
1997,  and $542,064  and $ -0-,  respectively,  for the year ending  January 31,
1996. The ESOP has 2,056,142, 2,045,316 and 1,676,640 shares of the total issued
and outstanding stock respectively at January 31, 1998, 1997 and 1996.

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.

The plan acquired 62,000, 0 and 137,076 shares during the Company's fiscal years
ended  January 31, 1998,  1997 and 1996,  respectively,  from  shareholders.  In
addition,  in fiscal year 1996,  231,600  shares were  purchased  from  treasury
stock. Shares distributed from the plan as a result of termination of employment
were 51,174,  0, and 0 during the Company's fiscal years ended January 31, 1998,
1997 and 1996. The shares' fair market value was determined based on the trading
value of common  shares of the Company at January  31,  1998 and on  independent
appraisal for January 31, 1997 and 1996.

NOTE 13 - SOFTWARE DEVELOPMENT COSTS (CONTINUED)

During the years ended January 31, 1998, 1997 and 1996, $1,149,685, $556,167 and
$161,785,  respectively,  of software development costs for computer software to
be sold or  otherwise  marketed  were  capitalized.  The  amortization  of costs
related to computer  software  product  development  held for sale was $304,397,
$108,757  and  $84,694  for the years ended  January  31,  1998,  1997 and 1996,
respectively.

In management's  opinion,  the net realizable  value of future sales exceeds the
carrying  value  of  unamortized  software  development  costs,   therefore,  no
adjustment to carrying value is required.

NOTE 15- SIGNIFICANT ESTIMATE

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.

NOTE 16 - RECLASSIFICATION

Deferred  income taxes in the January 31, 1996 statement of cash flows have been
reclassified to be consistent with the January 31, 1997 presentation.

NOTE 17 - CONCENTRATIONS OF CREDIT RISK

Financial  instruments that potentially subject the Company to concentrations of
credit risk consist 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 January 31, 1998 and
1997 was $3,694,629 and $754,282, respectively.

NOTE 18 - STOCK OPTIONS

On June 11, 1997, the Company  reserved 600,000 shares of Exigent's common stock
for its  nonqualified  stock option plan (Plan 1Q).  The terms of these  options
provide that the options are  exercisable  on the date of grant and expire three
years after the date the options were granted.  Plan 1Q is  administered  by the
Company's CEO. Plan 1Q gives broad powers to the CEO to administer and interpret
the plan,  including  the  authority  to select  the  individuals  to be granted
options and the  particular  form and  conditions  of each option  granted.  All
options  are  granted  at an  exercise  price of $2.25.  Awards  may be  granted
pursuant to Plan 1Q through June 11, 2007. Plan 1Q may be terminated  earlier by
the Board of Directors at its sole discretion.

On March 10, 1997, the Company reserved 200,000 shares of Exigent's common stock
for its  qualified  incentive  stock  option plan (Plan 2Q).  The terms of these
options provide that the options are exercisable on the date of grant and expire
three years after the date of grant.  Plan 2Q is  administered  by the Company's
CEO. Plan 2Q gives broad powers to the CEO to administer and interpret the Plan,
including the authority to select the  individuals to be granted options and the
particular form and conditions of each option  granted.  All options are granted
at an exercise price not less than one hundred  percent of the fair market value
at the date of grant.  The  purchase  price will be at least 110  percent of the
fair market value of the Company's  common stock on the date of the grant if the
optionee  owns more than ten percent of the total  combined  voting power of all
the classes of stock of the Company.  Awards may be granted  pursuant to Plan 2Q
through  March  9,  2007.  Plan 2Q may be  terminated  earlier  by the  Board of
Directors at its sole discretion.

On July 30, 1997, the Company  reserved  240,000  shares for a second  qualified
stock  incentive plan (Plan 3Q) under terms similar to the first qualified plan.
The terms of these  options  provide that the options are  exercisable  one year
from the date of grant and expire  three years after the date of grant.  Plan 3Q
is  administered  by the Company's CEO. Plan 3Q gives broad powers to the CEO to
administer  and  interpret  the Plan,  including  the  Authority  to select  the
individuals  to be granted  options and to  prescribe  the  particular  form and
conditions  of each  option  granted.  However,  a  Committee  of the  Board  of
Directors  shall approve each grant of an option  pursuant to Plan 3Q in advance
of issuance.  In addition,  the Plan  stipulates  that the  aggregate  number of
shares of stock for which  options may be granted  shall be allocated 50% to new
hire  employees and the remaining 50% to such  employees as the CEO shall select
at his  discretion.  All options are granted at an exercise  price not less than
100% percent of the fair market value at date of grant.  The purchase price will
be at least 110 percent of the fair market  value of  Exigent's  common stock on
the date of the grant if the  optionee  owns more then ten  percent of the total
combined  voting  power of all  classes of stock of the  Company.  Awards may be
granted  pursuant to Plan 3Q through  July 29, 2007.  Plan 3Q may be  terminated
earlier by the Board of Directors at its sole discretion.

NOTE 18 - STOCK OPTIONS (CONTINUED)

On September 30, 1997, the Company  reserved  120,000 shares of common stock for
its  non-qualified  non-employee  director  stock  option plan (Plan 5NQ).  Each
optionee who is granted options will receive 40,000 shares of common stock.  The
terms of these options  provide that the options are  exercisable on a quarterly
basis  following  grant at the  rate of  2,500  shares  per  quarter  for the 16
quarters  following grant date,  provided the optionee continues to serve on the
Board of  Directors.  Optionees  will be  eligible to receive a grant of options
upon their  initial  election to the Board.  All  options  will expire ten years
after the date of grant.  Plan 5NQ is  administered  by the  Company's  Board of
Directors or a committee  thereof.  All options are granted at an exercise price
equal to the fair market value of the Company's  common stock on the date of the
grant.  Awards may be granted  pursuant to Plan 5NQ through  September 30, 2007.
Plan  5NQ may be  terminated  earlier  by the  Board  of  Directors  at its sole
discretion.

Each plan noted above allows the plan administrator, in his discretion, to grant
stock appreciation  rights with each option granted.  As of January 31, 1998, no
stock appreciation rights had been granted.

At January 31, 1998, there were 25,000,  11,250,  203,600 and 80,000  additional
shares  available  for  grant  under  Plan 1Q,  Plan 2Q,  Plan 3Q and Plan  5NQ,
respectively.  Using  the  Black  Scholes  option-pricing  model,  the per share
weighted-average  fair value of stock options granted during 1998 where exercise
price equals the market price of the stock on the grant date was $0.8261.

The following weighted average assumptions were used:

                                                              1998

NOTE 18 - STOCK OPTIONS (CONTINUED)

The Company  applies APB Opinion No. 25 in accounting  for its option plans and,
accordingly,  no compensation  cost has been recognized for its stock options in
the financial  statements for stock options granted.  Had the Company determined

options  under SFAS No. 123,  the  Company's  net income and  earnings per share
would have been reduced to the pro forma amounts indicated below:

NOTE 20 -SOURCE OF LABOR SUPPLY

The  Company's  business of  providing  computer  services  and custom  software
programming is dependent upon having a supply of computer/engineering employees.
As a result of the  expansion of the number of business  users of computers  and
the expansion in demand for computer  services and custom software  programming,
there is a short supply of computer professionals. The situation is not expected
to improve in the near future. However, with the defense contractors having laid
off many of their  computer/engineering  employees  and the  trend  expected  to
continue,  there is currently a pool of employees who would likely have at least
some of the  expertise  needed by the Company.  In  addition,  the Company has a
competitive  benefit  package  it  believes  will  help to  attract  and  retain
qualified employees.

NOTE 20 - DEPENDENCE ON INDUSTRY

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

                          NOTES TO FINANCIAL STATEMENTS
               FOR THE YEARS ENDED JANUARY 31, 1998, 1997 AND 1996


NOTE 21 - COMMITMENTS AND CONTINGENCIES

The Company has outstanding  purchase  commitments of $145,309 as of January 31,
1998. These represent outstanding purchase orders for which neither the item nor
invoice has been received.

NOTE 22 - RELATED PARTY

STI paid $48,000 in  consulting  fees during the year ended January 31, 1996 and
issued  29,161  warrants  of STI on March 20, 1996 to a company for which one of
the  directors  of STI  provides  consulting  services.  The STI  warrants  were
converted  into  Exigent  warrants on January 30, 1997 (see Note 8).  Consulting
fees paid by STI to this  company  for the year ended  January 31, 1998 and 1997
were $45,485 and $94,620, respectively.

During  fiscal year 1997,  the director  discussed  above was also  Secretary of
Monogenesis  and Chairman and  controlling  shareholder of another  company that
received  shares of the stock of the Company  from  Monogenesis.  On January 31,
1998, this director's services were terminated and on March 23, 1998 he resigned
from the Board.

NOTE 23 - SUBSEQUENT EVENTS

In February,  1998,  the Company  entered  into an  additional  leased  facility
located  adjacent to its existing STI Melbourne  facility.  This new facility is
30,000 square feet and will house the Exigent corporate  headquarters,  FotoTag,
and product  development.  The lease is a 10 year lease with  expiration in
April, 2007.

At April 4, 1998, the Company was in the process of reserving  250,000 shares of
common stock for a qualified non-officers stock option plan (Plan 4Q). The terms
of these options  provide that the options are  exercisable on the date of grant
and expire three years after the options were granted.  Plan 4Q is  administered
by the Company's  CEO.  Plan 4Q gives broad powers to the CEO to administer  and
interpret  the plan,  including the  authority to select the  individuals  to be
granted  options and the particular  form and conditions of each option granted.
Options granted are to be tied to the corporate  financial  performance goals of
the officer's  plan.  All options are granted at an exercise price not less than
one  hundred  percent  of the  fair  market  value  on the date of grant of such
option. The purchase price will be at least 110 percent of the fair market value
of the Company's common stock on the date of the grant if the optionee owns more
than ten percent of the total combined  voting power of all the classes of stock
of the Company.  Awards may be granted within 10 years from the date the plan is
adopted. Plan 4Q may be terminated earlier by the Board of Directors at its sole
discretion.

In February of 1998,  the Company  announced  that it entered into  negotiations
related to an  acquisition.  The terms of the  acquisition,  including price and
acquisition date, have not yet been determined.

ITEM 9.   CHANGE  IN  AND  DISAGREEMENTS  WITH  ACCOUNTANTS  ON  ACCOUNTING  AND
          FINANCIAL DISCLOSURES

     On  March  18,  1998,  the  Board  of  Directors  of  the  Company  adopted
resolutions changing the Company's  certifying  accountant to Ernst & Young LLP.
The  engagement  letter was  executed  on March 20,  1998.  The  change  will be
effective  after the audit for the  fiscal  year ended  January  31,  1998.  The
certifying  accountant  for the previous years and the fiscal year ended January
31, 1998,  Hoyman,  Dobson & Company,  P.A.,  will  continue to provide  various
accounting  services to the Company  and its  subsidiaries.  The change was made
because the new certifying accountant has greater national name recognition.

     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.  The  Company  has not had any  disagreements  with  its
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 its two most recent fiscal years
or since then, the Company has not been advised by its principal accountant: (i)
that the  internal  controls  necessary  for the  Company  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 the Company's filing
on Form 8-K on March 30,  1998,  which  letter is attached as Exhibit 16 to such
Form 8-K.

                                 LEASE AGREEMENT

     THIS AGREEMENT is made the 14th day of May, 1993, by and between  HENDERSON
EVANS, L.C., a Florida limited liability company, and SOFTWARE TECHNOLOGY, INC.,
a Florida corporation ("Tenant").

     1. DEMISED PREMISES.  Landlord does hereby demise and let unto Tenant,  and
Tenant rents from Landlord, all that land ("Land") as shown on the recorded Plat
Plan for  Airport  Corporate  Center  for Lot Nos.  1 and 7,  together  with the
building of  appropriately  22,500 square feet  ("Building")  to be  constructed
thereon on behalf of Landlord in Airport Corporate Center ("Center"), Melbourne,
Brevard County,  Florida.  (Land and Building hereinafter  collectively "Demised
Premises"),  for a term  described  in  Paragraph  2 hereof,  and to be used and
occupied as office,  engineering,  manufacturing  and assembly  space and for no
other purpose.

     2. DEMISED TERM. This Lease shall be for a term of ten (10) years (plus any
partial month if the Commencement Date is other than the first day of the month)
("Demised Term"), unless earlier terminated pursuant to the terms of this Lease,
beginning  the date on which  Landlord  substantially  completes  the  leasehold
improvements,  as evidenced by a certificate of occupancy  issued by the City of
Melbourne,  in  accordance  with  Paragraph  5 hereof and  delivers  the Demised
Premises  to Tenant  ("Commencement  Date"),  and ending the last day of the one
hundred  twentieth (120th) month following the Commencement  Date,  ("Expiration
Date").  Within thirty (30) days following the Commencement  Date,  Landlord and
Tenant shall confirm the Commencement  Date in writing.  The  Commencement  Date
shall be as specified in Paragraph 6b. hereof.

     3. BASIC RENT.

          a. FIRST YEAR OF THE DEMISED TERM.  During the first Lease Year of the
Demised Term, Tenant agrees to pay a net Basic Rent ("Basic Rent") in the sum of
$166,500.00  per annum lawful money of the United States of America,  payable in
advance  during  the First  Year of the  Demised  Term of this  Lease in sums of
$13,875.00  on the first day of each  month,  rent to begin on the  Commencement
Date. Rent due and payable  without demand or offset,  at the office of Landlord
(Attention: Accounting Department).

          b. YEARS  2-10 OF THE  DEMISED  TERM AND  EXTENDED  TERMS.  During the
second through tenth Lease Years and any years during the Extended Term,  Tenant
agrees to pay a net Basic Rent ("Basic Rent") in the sum of: the previous Year's
Basic  Rent,  PLUS the lesser of: (i) an  adjustment  for  Consumer  Price Index
("CPI")  increase,  as defined below, or (ii) three percent (3%) of the previous
Year's Basic Rent.

          ADJUSTMENT FOR CPI INCREASE:  The CPI  adjustment for each  subsequent
          Year's Basic Rent shall be: an amount equal to the  percentage  change
          in the Consumer  Price Index,  as measured  from the Base Index to the
          Comparison  Index,  multiplied by the previous  Year's Basic Rent. For
          the purposes of this paragraph:

          (a) The CPI shall mean the  Consumer  Price Index (Base  Period  1967)
          (U.S.  city average for urban  consumers),  published by the Bureau of
          Labor  Statistics of the United States  Department of Labor;  provided
          that if such  Consumer  Price Index is no longer  published at regular
          periods,  then  any  similar  report  released  by any  other  bureau,
          department  or agency  of the  United  States  Government  at  regular
          periods, for substantially similar purposes, shall be used;

          (b) The Base Index  shall mean the most  recent  Consumer  Price Index
          published sixty (60) days prior to commencement of the Lease Year;

          (c) The  Comparison  Index shall mean the most recent  Consumer  Price
          Index published sixty (60) days prior to the end of the Lease Year.

          (d) Lease Year shall mean the twelve (12) month period starting on the
          Commencement  Date and each  anniversary  thereof  during the  Demised
          Term.

     4. NET LEASE.  It is the intent of the  parties  hereto  that this is a net
lease,  and that all  costs of  ownership,  maintenance  and use of the  Demised
Premises,  shall be paid by Tenant in  addition  to the  payments  of Basic Rent
specified above,  provided  however,  Landlord shall be responsible for property
management  expenses,  if any,  structural  repairs to the exterior  foundation,
roofs, the plumbing in common areas and/or outside of the Building, and exterior
walls (but  excluding the exterior of, and the frames  surrounding  all windows,
doors,  plate glass,  store fronts and signs).  Said repairs by Landlord will be
made within a reasonable  time after notice from Tenant.  Landlord shall provide
all Common  Area  Services  ("Common  Area  Services"  is  defined  as  exterior
janitorial services, grounds maintenance,  landscaping,  parking lot maintenance
and site lighting,  if applicable) to the Demised Premises, at Tenant's expense.
Tenant shall have the right to approve,  in advance,  all  contracts  for Common
Area Services for the Demised Premises.

     5. IMPROVEMENT OF DEMISED PREMISES.

          (a)  CONSTRUCTION  OF THE BUILDING.  After execution of this Lease and
initialing   of  the  final   plans  and   specifications   ("Final   Plans  and
Specifications")  for the  Building,  which Final Plans and  Specifications  are
attached hereto as Exhibit "A" and  incorporated  herein by reference,  Landlord
shall promptly make  application  for all building  permits and  approvals.  Any
changes to the Final  Plans and  Specifications  required  by Tenant  during the
building or fit-up of the Demised  Premises shall be by separate  written change
order  (including  payment  terms),  with an  extension  of time to complete the
building of the Demised Premises, if necessary, signed by both parties.

          (b) FIT-UP WORK.  Utilizing a general contractor selected by Landlord,
Landlord  shall complete and prepare the Demised  Premises for Tenant's  initial
occupancy  in  a  good  and  workmanlike  manner  in  accordance  with  Tenant's
Improvement Plan which has been initialed by both Landlord and Tenant.

          (c) MATERIALS  USED FOR FIT-UP WORK.  Landlord  shall use materials as
outlined on the attached Tenant Scope of Work (Exhibit "A").  Landlord  reserves
the right,  however:  (1) to make  substitutions of material of equivalent grade
and  quality  when  and if any  specified  material  shall  not be  readily  and
reasonably available,  and (2) to make changes necessitated by conditions met in
the course of construction,  provided that Tenant's approval of any change shall
first be obtained (which approval shall not be unreasonably withheld) so long as
there shall be general  conformity with Tenant's  Improvement Plans and Tenant's
intended use of the Demised  Premises and which approval must be given or denied
(with reasons stated in the case of denial) within  forty-eight (48) hours after
request or approval shall be conclusively deemed to have been given.

     6. INABILITY TO GIVE POSSESSION.

          (a) EXCUSABLE  DELAYS.  Landlord shall not be liable to Tenant for any
damages  caused by  Landlord's  inability to deliver  possession  of the Demised
Premises  to  Tenant on the  Commencement  Date,  as a result  of causes  beyond
Landlord's reasonable control,  including,  but not limited to, delays caused by
Tenant's  acts  or by  strikes,  lockouts,  labor  disputes,  inclement  weather
(including the day(s) following  inclement weather when construction work cannot
proceed  due  to  saturation  of  soils  or  other  unsatisfactory  conditions),
inability to procure materials, failure of power, restrictive governmental rules
and regulations, riots, insurrections or war ("Excusable Delays").

          (b) DELIVERY OF DEMISED  PREMISES.  If the Landlord shall be unable to
give possession of the Demised  Premises within nine (9) months of receiving the
building  permit  from the City of  Melbourne,  exclusive  of  Excusable  Delays
("Completion  Date"),  or  because  a  certificate  of  occupancy  has not  been
procured,  Landlord  shall not be subject to any liability for such inability to
give possession under such circumstances. The payment of rent shall not commence
until the  Commencement  Date. The failure to give  possession on the Completion
Date shall not affect the  validity of this Lease or the  obligations  of Tenant
hereunder or extend the Demised Term,  provided,  however, in the event Landlord
is unable to give possession on or before the tenth (10th) month after receiving
the building  permit from the township  (exclusive  of Excusable  Delays),  then
Tenant  shall  have the  option  of  declaring  the Lease  terminated  by giving
Landlord written notification  thereof, by registered mail, within two (2) weeks
of the first day of said tenth (10th) month.

     7. ADDITIONAL RENT.

          (a) BREACH. Tenant agrees to pay as rent in addition to the Basic Rent
any and all sums  which may  become  due by reason of the  failure  of Tenant to
comply with all of the  covenants of this Lease and any and all  damages,  costs
and expenses,  including attorney's fees, which the Landlord may suffer or incur
by reason of such default,  and also any and all damages to the Demised Premises
caused by any act or neglect of the Tenant.

          (b)  TAXES,  ASSESSMENTS,  ETC.  Tenant  will  duly  promptly  pay  as
additional rent to Landlord, as the same shall become due and payable and before
they become  delinquent,  all taxes,  rates,  assessments and other governmental
charges,  and charges of every kind and nature whatsoever,  nonrecurring as well
as  recurring,  special  or  extraordinary  as well as  ordinary,  foreseen  and
unforeseen,  and each and every installment  thereof,  which shall or may during
the term of the Lease be levied,  assessed or imposed, or become due and payable
or  become  liens  upon,  or arise in  connection  with  the use,  occupancy  or
possession  of, or any  interest  in, the Demised  Premises,  or upon the rents,
issues,  income and profits therefrom so as to prevent the same from becoming or
being an  enforceable  lien or claim  against the  property  or the  interest of
Landlord  ("Expenses").  Landlord  shall  apply  such  payment  by Tenant to the
payment of such Expenses, but in no event shall Landlord be required to pay such
Expenses early or during discount periods.  Such Expenses shall include all real
estate taxes,  assessments,  water and sewer charges which may become liens upon
the Demised  Premises or any part thereof.  If Landlord  requests  Tenant to pay
such  Expenses  other  than to  Landlord,  Tenant  will  furnish  or cause to be
furnished to Landlord not less than fifteen (15) days prior to the date on which
payment of the same would become delinquent,  or subject to penalty or interest,
receipts or other evidence  satisfactory  to Landlord of the payment of all such
Expenses.  If Landlord requests in writing,  Tenant shall pay to Landlord, or as
Landlord may direct,  such Expenses in advance in  installments as estimated and
determined by Landlord, and deposited with Landlord, or as directed by Landlord,
for  payment of all such  Expenses  when the same may  become  due and  payable.
Notwithstanding  the  foregoing,  Tenant  shall  not be  responsible  for  gross
receipts or other  income  taxes  incurred  by  Landlord  on the rents  received
hereunder  unless it is imposed in lieu of  another  charge for which  Tenant is
responsible hereunder.

          If the tenant deems  excessive or illegal any such Expenses,  with the
written consent of the Landlord,  the Tenant may make payment under protest. Any
contest,  whether  before  or  after  payment,  may be made  in the  name of the
Landlord or the Tenant or both,  with the written  consent of the  Landlord.  If
requested by Tenant,  Landlord may, but shall not be required to  participate in
any such  contest,  but the Tenant  shall be  entitled to any refund of any such
Expenses,  and any penalty or interest  thereon  which may have been paid by the
Tenant,  but all costs in  connection  with such  contest  shall be borne by the
Tenant.

          In case of  failure of the  Tenant to make any of the  payments  to be
made by Tenant for such  Expenses,  the Landlord  may, but shall not be required
to, pay the amount of same,  with  penalty and  interest  thereon,  if any.  The
amount so paid by the Landlord,  with interest  thereon from the date of payment
thereof  by the  Landlord,  shall  be  added  to and  become  a part of the next
installment of rent.

          If at any time  during the term of this Lease the  methods of taxation
prevailing  at the  commencement  of the term hereof shall be altered so that in
lieu of or as a supplement  to or a substitute  for the whole or any part of the
real estate  taxes or  assessments  now  levied,  assessed or imposed (1) a tax,
assessment, levy, imposition or charge, wholly or partially as a capital levy or
otherwise,  on the  rents  received  therefrom  or (2) a tax,  assessment,  levy
(including but not limited to any municipal,  state or federal levy), imposition
or charge measured by or based in whole or in part upon the premises and imposed
upon the Landlord,  or (3) a license fee measured by the rent payable under this
Lease, then all such taxes,  assessments,  levies or impositions and charges, or
the part  thereof so  measured  or based  shall be deemed to be  included in the
general real estate taxes and assessments  payable by the Tenant pursuant hereto
the extent that such taxes, assessments,  levies,  impositions and charges would
be  payable if the  premises  were the only  property  of the  Landlord  subject
thereto,  and the Tenant shall pay and discharge the same as herein  provided in
respect of the payment of general real estate taxes and assessments.

          (c) INSURANCE.  Landlord shall keep all buildings and improvements now
or hereafter erected upon the Demised Premises,  together with Chattels therein,
insured for the benefit of Landlord  against loss by fire and other  causalities
and hazards usually covered by extended coverage insurance in an amount not less
than the replacement  value of the Demised Premises  (excluding  foundations and
other parts below parts below the surface of the lowest  floor),  as  determined
not more than once  annually by an appraiser or rating  bureau  satisfactory  to
Landlord.  Tenant  agrees that it will,  throughout  the Demised  Term,  pay and
discharge  as  additional  rent,  the cost  incurred by Landlord in insuring the
Demised Premises as above stated. Insurance premiums at the beginning and end of
the term shall be apportioned. It is expressly understood and agreed that if for
any  reason  attributable  to  Tenant  it shall be  impossible  to  obtain  Fire
insurance on the building and  improvements on the Demised Premises in an amount
and in the form and with fire  insurance  companies  acceptable to the Landlord,
the Landlord may, if the Landlord elects,  (a) terminate this Lease and the term
thereof  on giving to the  Tenant  fifteen  (15)  days'  notice  in  writing  of
Landlord's  intention so to do and upon the giving of such notice this lease and
the  terms  thereof,  shall  terminate  and  come to an  end;  (b)  compute  the
additional  costs for such  insurance over and above the standard cost as if the
condition  attributable to Tenant did not exist and Tenant shall be obligated to
pay all of such additional cost.

          Tenant shall also provide at its sole cost and expense,  any insurance
on improvements  made to or inside the Demised  Premises by Tenant.  Such policy
shall name as insured  Landlord and Tenant,  as their  interests  may appear and
shall name  Landlord's  first  mortgagee,  if any, as mortgagee.  A copy of such
policy shall be furnished to Landlord and Landlord's first mortgagee.

          Tenant  at its own cost and  expense  will  provide  and keep in force
during the Demised Term of this Lease  commercial  general  liability  insurance
covering  at  least  the  hazards  of  "premises-operations",   "elevators"  (if
applicable) and "independent  contractors",  in which Landlord shall be included
as a named  insured,  in such other  limits of  liability  as may be required by
landlord   from  time  to  time,   but  not  less  than  One   Million   Dollars
($1,000,000.00)  combined  single  limit,  with a deductible  not to exceed Five
Thousand  Dollars  ($5,000.00).  Such insurance shall cover not only the Demised
Premises but shall also include all elevators,  hoists, hallways,  entranceways,
stairs or any other common areas  (exterior or  interior),  streets,  driveways,
alleys, lawns, parking and loading areas, sidewalks and curbs adjacent thereto.

          All such  policies  shall  contain  provision  for  notice to the said
Landlord not less than ten (10) days in advance of any  cancellation or material
change of such policy. In case of failure of the Tenant to make premium payments
when due,  the Landlord  may pay the amount of any such  premiums,  which amount
with interest thereon from the date of payment by Landlord shall be added to and
become part of the next installment of rent.

          Copies of renewal policies or certificates for any insurance  required
under this  Paragraph  shall be deposited  by Tenant with  Landlord at least ten
(10) days prior to the expiration of existing  policies,  and upon failure so to
do Landlord may immediately  purchase,  for the account of Tenant, the necessary
insurance from any reputable  insurance  company  without notice to Tenant,  and
Tenant shall  reimburse  Landlord  for cost  thereof  within ten (10) days after
demand.

          All insurance required hereunder shall be issued by companies licensed
to do business in Florida and  acceptable  to  Landlord.  Tenant  shall have the
right to carry the insurance provided for in this Paragraph,  or any portions of
such insurance under a blanket or comprehensive all-risks policy.

          (d) UTILITIES.  Tenant  further  agrees to pay as additional  rent all
charges for water, sewer, gas, oil, electricity,  light, heat, power,  telephone
or other utility used by Tenant at the Demised Premises during the Demised Term.
All charges for repair of the utility meter(s) on the Demised Premises,  whether
such repairs are made necessary by ordinary wear and tear, freezing,  hot water,
accident,  or other causes,  shall be payable by Tenant as  additional  rent and
shall be paid immediately when the same become due.

          (e)  MISCELLANEOUS.  Tenant  agrees  to pay  as  Additional  Rent  its
pro-rata share of all Center charges,  as set forth in Paragraph 35 hereof, for:
signage  repairs,   exterior   janitorial   service,   grounds  maintenance  and
landscaping,  parking lot maintenance,  fences and site lighting. Landlord shall
perform,  at Tenant's cost and expense,  the grounds  maintenance,  landscaping,
parking lot  maintenance  and site  lighting  for the Demised  Premises and bill
Tenant the cost for same as Additional Rent.

     8. TIME,  PLACE AND  WITHHOLDING  OF  PAYMENT.  Unless  provided  otherwise
herein,  all Basic Rent and additional  rent shall be payable in advance without
prior  notice or demand and without any set off or deduction  whatsoever  at the
office of Landlord  (or at such other  place as  Landlord  may from time to time
designate by notice in writing) and at the times provided for the payment of the
Basic Rent. Under no circumstances  will Tenant be permitted to withhold for any
reason.

structural  changes  or  requirements  of  whatever  nature,  or to  changes  or
requirements incident thereto, or as the result of the use or occupation thereof
by Tenant,  and the Tenant shall pay all costs and expenses  incidental  to such
compliance, and shall indemnify and save harmless the Landlord from all expense,

against or imposed  upon the Demised  Premises or against the  Landlord as owner
thereof,  because of the  failure of the  Tenant to comply  with this  covenant.
Tenant  further  agrees  to keep the  Demised  Premises  clean and free from all
ashes,  dirt and other refuse matter;  replace all glass windows,  doors,  etc.,

the  Demised  Premises  (except  as  specifically   provided  otherwise  herein)
occasioned by any event  happening on or about the Demised  Premises,  hallways,
entranceways,   stairs  or  any  other  common  areas  (exterior  or  interior),
elevators, hoists, streets, driveways, parking and loading areas, alleys, lawns,
sidewalks and curbs adjacent thereto  including those resulting from any work in
connection with any alterations, changes, new construction or demolition, except

employees.  Tenant is  subrogated  to any rights of  Landlord  against any other
parties  in  connection  therewith.  Tenant  shall  defend,  indemnify  and hold
harmless Landlord from and against any and all claims,  demands, suits, damages,
liability and costs (including  counsel fees and expenses)  arising out of or in

     13. DAMAGE TO DEMISED PREMISES.

          (a) In the event that the Demised Premises is totally  destroyed or so
damaged by fire or other  casualty not occurring  through fault or negligence of
the Tenant or those employed by or acting for him, that, in Landlord's judgment,
the same cannot be repaired or restored  within one hundred  eighty  (180) days,
this Lease shall absolutely cease and determine,  and the rent shall abate as of
the date of casualty  for the balance of the term.  If  Landlord  cannot  locate
alternate  space for  Tenant to  continue  operation  during  the  course of the
repairs,  then Tenant shall have the right to terminate this Lease within thirty
(30) days.

may, at its option,  restore the same (excluding fixtures and improvements owned
by Tenant) with  reasonable  promptness,  reserving  the right to enter upon the
Demised Premises for that purpose. The Landlord also reserves the right to enter
upon the Demised Premises whenever  necessary to repair damage caused by fire or
other  casualty to the  building of which the Demised  Premises is a part,  even
though  the effect of such entry be to render  the  Demised  Premises  or a part
thereof  untenantable.  In  either  event  the  rent  shall be  apportioned  and
suspended during the time the Landlord is in possession, taking into account the
portion of the Demised  Premises  rendered  untenantable and the duration of the
Landlord's  possession.  If a dispute  arises as to the amount of rent due under
this clause,  Tenant agrees to pay the full amount  claimed by Landlord.  Tenant
shall,  however, have the right to proceed by law to recover the excess payment,
if any.

          (c) Landlord  shall make such election to repair the Demised  Premises
or terminate  this Lease by giving  notice  thereof to Tenant within thirty (30)
days from the day Landlord  received  notice that the Demised  Premises had been
destroyed or damaged by fire or other casualty.

          (d)  Notwithstanding the fact that Landlord may have elected to repair
the Demised  Premises  within said  thirty  (30) day  period,  if the  mortgagee
chooses to  accelerate  the mortgage due to damage by fire or other  casualty to
the Demised  Premises or the  building of which the Demised  Premises is a part,
Landlord  shall have the right to rescind  and/or cancel said election to repair
and  shall  have the right to elect not to repair  the  damaged  to the  Demised
Premises or the building of which the Demised Premises is a part,  provided said
notification  of election  not to repair is given to Tenant  within  thirty (30)
days after date of the receipt of said notice of acceleration.

          (e) Landlord shall not be liable for any damage, compensation or claim
by reason of inconvenience or annoyance  arising from the necessity of repairing
any  portion  of  the  building,  the  interruption  in the  use of the  Demised
Premises,  or the  termination of this Lease by reason of the destruction of the
Demised Premises.

     14. MISCELLANEOUS AGREEMENTS AND CONDITIONS.

          (a)  NON-WAIVER BY LANDLORD OR TENANT.  The failure of the Landlord or
Tenant to insist upon strict  performance  of any of the covenants or conditions
to this Lease,  or to exercise  any option  herein  conferred in any one or more
instances,  shall not be construed as a waiver or relinquishment  for the future
of any such covenants or conditions of this Lease or option,  but the same shall
be and remain in full force and effect.

          (b)  ACCORD  AND  SATISFACTION.  No  payment  by Tenant or  receipt by
Landlord of a lesser  amount than the monthly  rent herein  stipulated  shall be
deemed to be other than on account of the earliest  stipulated  rent,  nor shall
any endorsement or statement on any check or any letter  accompanying  any check
or payment as rent be deemed an accord and satisfaction, and Landlord may accept
such check or payment  without  prejudice  to  Landlord's  right to recover  the
balance of such rent or pursue any other remedy herein.

          (c)  JURISDICTION  AND  LAW.  Tenant  hereby  subjects  itself  to the
jurisdiction of the Court of Brevard County,  Florida.  The laws of the State of
Florida shall be applicable to this lease and any interpretations thereof.

Improvements as required by Paragraph 5, and without any  representations on the
part of Landlord, his officers, employees, servants and/or agents.

of the  Tenant by any  governmental  officer  or agency  pursuant  to  statutory
authority for the dissolution, rehabilitation,  reorganization or liquidation of
the  Tenant;  or if there is the making by the Tenant of an  assignment  for the
benefit of creditors;

          Then and in any of said  events,  there shall be deemed to be a breach
of this Lease, and thereupon Landlord shall have the following rights:

          (1) To  accelerate  the  whole  or any  part  of the  Basic  Rent  and
additional rent (sometimes  collectively referred to herein as "Rent") and other
charges, payments, costs and expenses herein agreed to be paid by Tenant for the
entire unexpired balance of the term of this Lease, and any Rent, other charges,
payments, costs and expenses if so accelerated shall, in addition to any and all
installments  of Rent  already due and payable and in arrears,  and/or any other
charge,  expense or cost herein agreed to be paid by Tenant which may be due and
payable  and in  arrears,  be  deemed  due and  payable  as if, by the terms and
provisions of this Lease,  such  accelerated  Rent and other charges,  payments,
costs and expenses were on that date payable in advance, provided, however, that
Landlord agrees it will not exercise this remedy unless Tenant is in arrears for
a total of three (3) monthly installments of Base Rent under the Lease.

          (2) To enter the Demised Premises and without further demand or notice
proceed to distrain and sell the goods,  chattels and  personal  property  there
found,  to  levy  the  Rent  and  Tenant  shall  pay  all  costs  and  officers'
commissions,  including watchmen's wages and sums chargeable to Landlord, and in
such case all costs,  officers'  commissions and other charges shall immediately
attach and become part of the claim of Landlord for Rent, and any tender of rent
without  said costs,  commissions  and  charges  made,  after the  issuance of a
warrant of distress, shall not be sufficient to satisfy the claim of Landlord.

          (3) To re-enter the Demised Premises and remove all persons and all or
any  property  therefrom,  either by summary  dispossess  proceedings  or by any
suitable  action or  proceeding  at law,  without  being  liable to  indictment,
prosecution or damages  therefor,  and repossess and enjoy the Demised Premises,
together  with all  alterations,  fixtures,  signs  and other  installations  of
Tenant. Upon recovering possession of the Demised Premises by reason of or based
upon or  arising  out of a  default  on the part of  Tenant,  Landlord  may,  at
Landlord's  option,  either  terminate this Lease or make such  alterations  and
repairs as may be necessary in order to relet the Demised Premises and relet the
Demised  Premises or any part or parts  thereof,  either in  Landlord's  name or
otherwise,  for a term or terms which may at  Landlord's  option be less than or
exceed the period which would otherwise have constituted the balance of the term
of this Lease and at such rent or rents and upon such other terms and conditions
as in  Landlord's  sole  discretion  may seem  advisable  and to such  person or
persons as may in Landlord's  discretion seem best; upon each such reletting all
rents received by Landlord from such reletting  shall be applied:  first, to the
payment  of any  indebtedness  other  than  rent due  hereunder  from  Tenant to
Landlord;  second,  to the payment of any costs and expenses of such  reletting,
including  brokerage fees and attorney's fees and all costs of such  alterations
and repairs;  third,  to the payment of Rent due and unpaid  hereunder;  and the
residue, if any, shall be held by Landlord and applied in payment of future Rent
as it may become due and payable  hereunder.  If such rentals received from such
reletting  during any month shall be less than that to be paid during that month
by  Tenant  hereunder,  Tenant  shall  pay such  deficiency  to  Landlord.  Such
deficiency  shall be  calculated  and paid  monthly.  No such re-entry or taking
possession  of  the  Demised  Premises  or  the  making  of  alterations  and/or
improvements  thereto or the reletting thereof shall be construed as an election
on the part of Landlord to terminate  this Lease unless  written  notice of such
intention  be given to Tenant.  Landlord  shall in no event be liable in any way
whatsoever  for failure to relet the Demised  Premises or, in the event that the
Demised  Premises or any part or parts thereof are relet, for failure to collect
the rent thereof under such reletting. Tenant, for Tenant and Tenant's successor
and assigns,  hereby  irrevocably  constitutes and appoints Landlord as Tenant's
and  Landlord's  agent to  collect  the rents  due and to  become  due under all
subleases  of the  Demised  Premises  or any parts  thereof  without  in any way
affecting Tenant's obligation to pay any unpaid balance of Rent due or to become
due hereunder.  Notwithstanding any such reletting without termination, Landlord
may at any time  thereafter  elect to  terminate  this  Lease for such  previous
breach.

          (4) To terminate  this Lease and the term hereby  created  without any
right on the part of Tenant to waive the forfeiture by payment of any sum due or
by other  performance  of any  condition,  term or  covenant  broken.  Whereupon
Landlord  shall be  entitled  to  recover,  in  addition to any and all sums and
damages for violation of Tenant's obligations hereunder in existence at the time
of such  termination,  damages for  Tenant's  default in an amount  equal to the
greater of (i) amount of the Rent  reserved for the balance of the Demised Term,
as well as all other charges,  payments,  costs and expenses herein agreed to be
paid by Tenant,  also  discounted  at the rate of nine percent (9%) per annum to
its then present worth or (ii) three (3) months' rent, all of which amount shall
be immediately due and payable from Tenant to Landlord as liquidated damages.

     16.  RIGHT TO  INJUNCTIVE  RELIEF.  In the event of a breach or  threatened
breach by Tenant of any of the covenants or provisions  hereof,  Landlord  shall
have the right of injunction  and the right to invoke any remedy  allowed at law
or in equity,  as if re-entry,  summary  proceedings and other remedies were not
herein provided for.

     17.  RIGHTS NOT  EXCLUSIVE.  No right or remedy  herein  conferred  upon or
reserved to Landlord  is intended to be  exclusive  of any other right or remedy
herein or by law provided but each shall be cumulative  and in addition to every
other right or remedy  given  herein or now or  hereafter  existing at law or in
equity or by statute.

     18. WAIVERS BY TENANT. Tenant expressly waives the right to delay execution
on any real  estate  that may be levied  upon to collect  any  amount  which may
become  due under the terms and  conditions  of this Lease and any right to have
the same appraised. Tenant agrees that said real estate may be sold on a writ of
execution or other process.

     19.  CALCULATIONS  OF  AMOUNTS  DUE.  For the  purpose of  calculating  the
accelerated  Rent payable under paragraph (1) of Paragraph 15(d) of this Article
and the  "Rent  reserved  for the  balance  of the  term" of this  Lease for the
purposes of Paragraph (4) of Paragraph 15(d) of this Article, the amount payable
as Tenant's share of real estate taxes,  Tenant's share of the cost of insurance
on the Demised Premises and Tenant's share of common area  maintenance  expenses
and any other charges for which Tenant is responsible  hereunder for the balance
of the term  hereof  shall be equal  to the sum of the  highest  amount  paid or
payable  by  Tenant  in any  calendar  year  for  each  of the  foregoing  items
multiplied by the number of calendar years  (including  any fractional  calendar
year) remaining in the term of this Lease.

     20. RIGHT OF ASSIGNEE OF LANDLORD.  The right to pursue the remedies herein
provided against Tenant and to enforce all of the other provisions of this Lease
may, at the option of any  assignee of this Lease,  be exercised by any assignee
of the Landlord's  right,  title and interest in this Lease in his, her or their
own name,  any  statute,  rule of  court,  custom or  practice  to the  contrary
notwithstanding.

     21. REMEDIES CUMULATIVE. All of the remedies hereinbefore given to Landlord
and all rights and remedies  given to it by law and equity  shall be  cumulative
and concurrent.  No termination of this Lease or the taking or recovering of the
Demised  Premises  shall  deprive  Landlord  of any of its  remedies  or actions
against  Tenant  for rent or sums  due at the time or  which,  under  the  terms
hereof, would in the future become due as if there has been no termination;  nor
shall the bringing of any action for rent or breach of  covenant,  or the resort
to any other remedy  herein  provided for the recovery of rent be construed as a
waiver of the right to obtain possession of the premises.

     22. CONDEMNATION.  If at any time during the Demised Term or any renewal or
extension  thereof the Demised  Premises,  or any portion  thereof,  be lawfully
condemned or conveyed in lieu or  condemnation,  the Landlord  shall be entitled
to, and shall  receive  the award or  payment  therefor,  and the  Tenant  shall
assign,  and does  hereby  assign and  transfer  to the  Landlord  such award or
payment  as may be made  therefor,  and in no event and  under no  circumstances
shall the  Tenant be  entitled  to receive or retain any award or payment of any
part thereof. This Lease shall, as to the part so taken terminate as of the date
title shall vest in the  condemnor,  and rent shall abate in  proportion  to the
square feet of the leased space taken or condemned.

     23. EXECUTION OF ESTOPPEL CERTIFICATE.  At any time, and from time to time,
upon the  written  request of  Landlord or any first  mortgagee,  Tenant  within
twenty  (20) days of the date of such  written  request  agrees to  execute  and
deliver to Landlord  and/or such first  mortgagee,  without charge and in a form
satisfactory  to  Landlord  and/or  such  mortgagee,  a written  statement:  (a)
ratifying this Lease; (b) confirming the commencement and expiration date of the
term of this Lease and the minimum  annual rental rate payable  during the lease
term; (c) certifying  that Tenant is in occupancy of the Demised  Premises,  and
that the Lease is in full force and effect and has not been modified,  assigned,
supplemented  or  amended  except  by such  writings  as  shall be  stated;  (d)
certifying  that all conditions and agreements  under this Lease to be satisfied
or performed by Landlord have been  satisfied  and performed  except as shall be
stated; (e) certifying that Landlord is not in default under the Lease and there
are no defenses or offsets  against the enforcement of this Lease by Landlord or
stating the defaults and/or defenses claimed by Tenant;  (f) reciting the amount
of advance rent, if any, paid by Tenant and the date to which such rent has been
paid and, if requested by Landlord and/or Mortgagee,  agreeing that Tenant shall
not pay rent to Landlord  more than thirty days in  advance;  (g)  reciting  the
amount of security  deposited with Landlord,  if any; (h) certifying that Tenant
has no option or right of first  refusal to  purchase  the  Demised  Premises or
option to extend  the term of the Lease  (unless  specifically  set forth to the
contrary in the Lease); (i) if requested by Landlord and/or Mortgagee,  agreeing
that the Lease will not be  modified  without the prior  written  consent of the
Mortgagee;  (j)  certifying  that tenant  will not  generate,  store,  handle or
otherwise  deal with any amount of any hazardous  substances or hazardous  waste
(as defined in federal,  state and local law) in or about the Demised  Premises,
in excess of those levels or quantities specified for regulatory  purposes;  (k)
agreeing, if requested by Mortgagee, that Tenant will give Mortgagee such notice
of any default by Landlord and reasonable  opportunity to cure such default, not
in excess of thirty (30) days,  unless the default  cannot be cured  within said
time,  before  exercising  Tenant's  remedies under the Lease; and (l) any other
information which Landlord or the mortgagee shall require.

     24.  FAILURE  TO EXECUTE  ESTOPPEL  CERTIFICATE.  The  failure of Tenant to
execute,  acknowledge  and  deliver to  Landlord  and/or any first  mortgagee  a
statement in  accordance  with the  provisions  of Paragraph 23 above within the
said twenty (20) day period shall constitute  acknowledgment by Tenant which may
be relied  upon by any person  holding or  intending  to  acquire  any  interest
whatsoever  in the  Demised  Premises  that this  Lease  has not been  assigned,
amended,  changed,  or modified,  is in full force and effect and that the Basic
Rent and additional rent have been duly and fully paid not beyond the respective
due dates  immediately  preceding the date of the request for such statement and
shall  constitute as to any persons entitled to rely on such statements a waiver
of any defaults by Landlord or defenses or offsets  against the  enforcement  of
this Lease by Landlord which may exist prior to the date of the written request,
and  Landlord at its option,  may treat such  failure as a  deliberate  event of
default.

     25. SUBORDINATION AND ATTORNMENT. Tenant agrees:

          (a) that,  except as hereinafter  provided,  this Lease is, and all of
Tenant's  rights  hereunder are and shall always be, subject and  subordinate to
any first mortgage ("First Mortgage"); and

          (b) That if the holder of any such First Mortgage  ("Mortgagee") or if
the  purchaser  at any  foreclosure  sale or at any  sale  under a power of sale
contained  in any  Mortgage  shall at its sole  option so  request,  Tenant will
attorn to, and  recognize  such  mortgagee or  purchaser,  as the case may be as
Landlord  under this Lease for the balance  then  remaining  of the term of this
Lease, subject to all terms of this Lease; and

          (c) That the  aforesaid  provisions  shall  be  self-operative  and no
further  instrument or document shall be necessary  unless  required by any such
First Mortgagee or purchaser. Notwithstanding anything to the contrary set forth
above,  any First  Mortgagee  may at any time  subordinate  its Mortgage to this
Lease,  without Tenant's consent,  by notice in writing to Tenant, and thereupon
this  Lease  shall be  deemed  prior to such  Mortgage  without  regard to their
respective dates of execution,  delivery and/or recording and in that event such
First  Mortgagee shall have the same rights with respect to this Lease as though
this Lease had been  executed and a  memorandum  thereof  recorded  prior to the
execution,  delivery and  recording of the Mortgage and as though this Lease had
been assigned to such First Mortgagee. Should Landlord or any First Mortgagee or
purchaser desire  confirmation of either such  subordination or such attornment,
as the case may be,  Tenant upon written  request,  and from time to time,  will
execute and deliver  without charge and in form  satisfactory  to Landlord,  the
First  Mortgagee or the purchaser all instruments  and/or  documents that may be
requested to  acknowledge  such  subordination  and/or  agreement to attorn,  in
recordable form.

          (d) Landlord  agrees that is shall  procure from the mortgagee who has
agreed  to  provide a  commitment  for a  five-year  permanent  mortgage  on the
Property  the  mortgagee's  consent  to a  non-disturbance  agreement,  in  form
reasonably  satisfactory  to Tenant,  which approval  shall not be  unreasonably
withheld.  If Landlord is unable to produce said  agreement  from such mortgagee
prior to the closing of the  construction  mortgage,  then Tenant shall have the
right to terminate  this  Agreement  within five (5) days after  receipt of such
advice from Landlord.

          Landlord further agrees that it shall use reasonable efforts to obtain
a similar agreement from any successor first mortgagee.

     26. FAILURE TO EXECUTE INSTRUMENTS AND DOCUMENTS. In the event Tenant fails
to execute  and  deliver  the  instruments  and  documents  as  provided  for in
Paragraphs  23 and 25 within  twenty  (20) days  after  request  in  writing  by
Landlord or such First  Mortgagee or purchaser,  as the case may be, Tenant does
hereby  make,  constitute  and  appoint  Landlord  or such  First  Mortgagee  or
purchaser,  as the case may be, as  Tenant's  attorney-in-fact  and in its name,
place and stead to do so, or  Landlord  may treat such  failure as a  deliberate
event of default.  The  aforesaid  power of attorney is given as coupled with an
interest and is irrevocable.

     27. QUIET ENJOYMENT;  EVICTION BY FORECLOSURE.  Tenant,  on paying the rent
reserved,  and performing all the covenants and conditions hereof,  shall at all
times during the Demised Term,  peaceably  and quietly have,  hold and enjoy the
Demised  Premises;  provided,  however,  eviction of the Tenant by reason of the
foreclosure of any First Mortgage now or hereafter on the Demised Premises shall
not be  construed as a breach of this  covenant,  nor shall any action by reason
thereof be brought against the Landlord;  and provided further, that no eviction
of the Tenant for any reason whatsoever,  after the Landlord shall have conveyed
the fee of the Demised Premises shall be construed as a breach of this covenant,
and no action therefor shall be brought against the Landlord.

     28. TERMINATION OF LEASE.

     It is hereby  mutually  agreed that either party hereto may terminate  this
Lease at the end of the Demised  Term or at the end of either  option  period by
giving  to the other  party  written  notice  thereof  at least  180 days  prior
thereto,  but in default of such notice, this Lease shall continue upon the same
terms and conditions in force immediately prior to the expiration of the Demised
Term  hereof as are  herein  contained  except  for Basic  Rent  which  shall be
adjusted to reflect the then current  market rates for space  comparable  to the
Demised Premises as determined by Landlord based upon other of Landlord's rental
properties for Melbourne,  Florida,  for a further period of one years and so on
from year to year unless or until termination by either party hereto, giving the
other one hundred  eighty  (180) days  written  notice for  removal  previous to
expiration of the then current term; PROVIDED,  however,  that should this Lease
be continued for a further period under the terms  herein-above  mentioned,  any
allowances  given  Tenant on the Basic Rent during the  original  term shall not
extend beyond such original term. In the event that Tenant shall give notice, as
stipulated in this Lease, of intention to vacate the Demised Premises at the end
of the Demised  Term,  or any renewal or  extension  thereof,  and shall fail or
refuse so to vacate the same on the date  designated by such notice,  then it is
expressly agreed that Landlord shall have the option either:

          (a) To  disregard  the notice so given as having no  effect,  in which
case all the terms and  conditions of this Lease shall continue  thereafter,  as
set forth above, with full force precisely as if such notice has not been given,
or

          (b)  Landlord  may, at any time  within  thirty days after the Demised
Term or any renewal or extension  thereof,  as  aforesaid,  give the said Tenant
fifteen (15) days' written  notice of his intention to terminate the said Lease;
whereupon the Tenant  expressly agrees to vacate said premises at the expiration
of the said fifteen (15) day period.

     All powers  granted to  Landlord  by this  lease may be  exercised  and all
obligations  imposed  upon Tenant by this Lease shall be  performed by Tenant as
well  during  any  extension  of the  Demised  Term of this  Lease as during the
Demised Term itself.

     29.  NOTICES.  All notices  required shall be in writing given by certified
mail, return receipt requested or by a recognized overnight delivery service:

     30. MECHANIC'S LIENS.

          (a)  MECHANIC'S  LIENS   PROHIBITED.   Tenant  shall  not  suffer  any
mechanic's  lien to be filed  against  the  Demised  Premises by reason of work,
labor,  services or materials performed or furnished to Tenant or anyone holding
the  Demised  Premises,  or any part  hereof,  through or under  Tenant.  If any
mechanic's  lien or any notice of intention  to file a mechanic's  lien shall at
any time be filed against the Demised  Premises  Tenant shall at Tenant's  cost,
within  fourteen  (14) days  after  knowledge  or  notice  of the  filing of any
mechanic's lien cause the same to be removed or discharged of record by payment,
bond, order of a court of competent jurisdiction, or otherwise.

          (b)  LANDLORD'S  REMEDY FOR TENANT'S  BREACH.  If Tenant shall fail to
remove or  discharge  any  mechanic's  lien or any notice of intention to file a
mechanic's lien within the prescribed  time, then in addition to any other right
or remedy of  Landlord,  Landlord  may,  at its  option,  procure the removal or
discharge  of the same by  payment  or bond or  otherwise.  Any  amount  paid by
Landlord  for such  purpose,  together  with all  legal and  other  expenses  of
Landlord  in  procuring  the  removal  or  discharge  or such  lien or notice of
intention  and together with interest  thereon at the highest  permissible  rate
shall be and become due and payable by Tenant to Landlord  as  additional  rent,
and in the event of Tenant's  failure to pay therefor  within  fifteen (15) days
after  demand,  the same shall be added to and be due and payable  with the next
month's rent.

          (c) NON-CONSENT OF LANDLORD TO FILING OF LIENS.  Nothing  contained in
this Lease  shall be  construed  as a consent on the part of Landlord to subject
Landlord's  estate in the Demised Premises to any lien or liability  arising out
of Tenant's use or occupancy of the premises.

     31. LEASE CONTAINS ALL AGREEMENTS. It is expressly understood and agreed by
and  between the  parties  hereto  that this Lease sets forth all the  promises,
agreements,  and conditions or understandings  between Landlord or his Agent and

agreements,  conditions or understandings,  either oral or written, between them
other  than are herein set forth.  It is  further  understood  and agreed  that,

Lease may be given by or to any one  thereof,  and shall have the same force and

wherever  stated herein,  shall be deemed to refer to the "Landlord" or "Tenant"
whether  such  Landlord  or Tenant be  singular  or plural and  irrespective  of
gender. No rights, however, shall inure to the benefit of the assignee of Tenant
unless the  assignment to such assignee has been approved by Landlord in writing
as aforesaid.

     33. SECURITY DEPOSIT. INTENTIONALLY OMITTED.

     34.  HEADINGS  NO PART OF LEASE.  Any  headings  preceding  the text of the
several paragraphs and subparagraphs  hereof are inserted solely for convenience
of reference and shall not constitute a part of this Lease nor shall they affect
its meaning, construction or effect.

     35. TENANT'S  PRO-RATA SHARE OF CENTER:  19.2%  (determined by dividing the
acreage of the Center (20.85 acres) by the acreage of the Land  (including  area
covered by the Building) (4.0 acres).

     36. LATE PAYMENT. In the event that any payment of Basic Rent or additional
rent or any other charge  required to be paid by Tenant under the  provisions of
this Lease,  shall not be paid within fifteen (15) days of the due date,  Tenant
shall  pay to  Landlord  a late  charge of five  (5%)  percent  of such past due
payment; and such late charge shall be deemed "rent" for all purposes under this
Lease.

     37.  LANDLORD'S  CONSENT.  Landlord  agrees that it shall not  unreasonably
withhold any consent required of it under this Lease.

     38.  SEVERABILITY.  If a provision of this Lease Agreement is held invalid,
it is  hereby  agreed  that all valid  provisions  that are  severable  from the
invalid  provision  remain in effect.  If a provision in this Lease Agreement is
held invalid in one or more of its applications, the provision remains in effect
in all valid applications.

     39. LANDLORD'S LIABILITY.  Anything to the contrary herein notwithstanding,
Landlord's  liability for any damages or assessments  hereunder shall be limited
solely to  Landlord's  interest in the Demised  Premises or land and building of
which the Demised Premises is part, as the case may be. It is further covenanted
and agreed by the parties  hereto  that in no case shall the  Landlord be liable
for any consequential damages.

     40.  SIGNAGE.  Tenant  shall have the right to place  neat,  professionally
executed  signs at the front entrance  and/or loading areas as shall  adequately
advertise Tenant's occupancy of the Premises and direct visitors, guests and the

ordinances  applicable  thereto.  Tenant shall not place any sign on any part of
the Building  without the written  consent of Landlord,  which consent  Landlord
shall not unreasonably withhold.

     41. LANDLORD'S ENVIRONMENTAL CLAUSE.

          (a) Tenant  shall not cause,  allow or permit the escape,  disposal or
release of toxic or hazardous substances or materials, including those which are
biologically  active or  chemically  active,  which  shall  include,  but not be
limited to, those substances  listed in the Environmental  Statutes,  as defined
below,  polychlorinated  biphenyls ("PCB's"),  asbestos and materials containing
PCG's and asbestos (hereinafter collectively "Hazardous Materials"),  in, around
or from the Demised  Premises.  Tenant shall not store, use or allow the storage
or use of Hazardous  Materials  in or around the Demised  Premises in any manner
not  sanctioned by law or the highest  standards  prevailing in the industry for
handling  and storage of such  Hazardous  Materials.  In the event that any such
Hazardous  Materials are required to be used by Tenant in the ordinary course of
its business,  Tenant shall send at least five (5) days' advance  written notice
to Landlord of the uses of such substances, including any identification of such
substances or materials. Landlord may deny or restrict Tenant's use or manner of
use of such  Hazardous  Materials  in or around the Demised  Premises;  however,
Landlord's failure to deny or restrict Tenant's use of Hazardous Materials or to
advise  Tenant of an  objection  to Tenant's use or manner of use of same in the
Demised Premises does not indicate  Landlord's  approval of such use and, in any
event,  Tenant  shall  remain  strictly  responsible  and liable for any and all
consequences,  direct  or  indirect,  resulting  from the use of such  Hazardous
Materials in or around the Demised Premises.

          (b) Tenant  shall  conduct all of its  operations  at the  Premises in
compliance  with all  federal,  state and  local  statutes  (including,  but not
limited to the Comprehensive Environmental Response, Compensation, and Liability
Act, 42 U.S.C. Section 9601 et. seq., as amended by the Superfund Amendments and
Reauthorization  Act of 1986,  Pub. L. No. 99-499,  100 Stat.  1613 (October 17,
1986) ("CERCLA"); the Resources Conservation and Recovery Act, 42 U.S.C. Section
6901  et.  seq.  ("RCRA"),  Florida  Air and  Water  Pollution  Control  Act and
regulations   enacted   thereunder),   ordinances,   regulations,   orders   and
requirements of common law, regarding, but not limited to, (i) discharges to the
air,  soil,  surface or  groundwater;  and (ii)  handling,  utilizing,  storage,
treatment or disposal of any hazardous substances or toxic substances as defined
therein ("Environmental Statues").  Tenant shall obtain all permits, licenses or

          (d) If,  because of the manner in which Tenant  operates its business,

testing by an environmental  testing entity of its choice,  to ascertain whether
there has been a release of Hazardous Materials by Tenant, its agents, servants,

Premises.

          (e) Tenant  hereby  agrees to indemnify  Landlord and to hold Landlord

     THIS IS A RIDER  MADE THIS 14TH DAY OF MAY,  1993,  TO THE LEASE OF MAY 14,
1993, BETWEEN HENDERSON EVANS,  L.C., a Florida limited liability  company,  and
SOFTWARE TECHNOLOGY, INC., a Florida corporation ("Tenant").

     OPTION TO PURCHASE.

     Landlord  hereby  grants to Tenant the  following  options to purchase  the
Demised Premises. Said options are personal to Tenant and may not be assigned by
Tenant with or without the  assignment of the Lease and are under and subject to
the following terms and conditions:

          a. Said options shall be exercised, if at all:

               (i) at least  ninety  (90) days  prior to the  expiration  of the
          fifth year of the Demised  Term of the Lease,  by written  notice from
          Tenant to Landlord by certified mail at Landlord's  last known address
          ("Option A"); or

               (ii)  at  least  one  hundred  eighty  (180)  days  prior  to the
          expiration  of the tenth year of the Demised  Term of the Lease,  with
          written  notice by Tenant to Landlord by certified  mail at Landlord's
          last known address ("Option B").

               (b) The purchase price for the Demised Premises shall be its fair
          market  value  (but in no event  less  than the  outstanding  mortgage
          balance against said Property) as determined by appraisal conducted in
          the following manner:

               (i)  Tenant  shall  include  with its notice of  exercise  of the
          option its name,  address and qualifications as set forth in paragraph
          b(iv) hereof of its nomination for an appraiser.

               (ii)  Within  ten (10) days  thereafter,  Landlord  shall  advise
          Tenant in writing of the name, address and qualifications as set forth
          in paragraph b(iv) hereof its selected appraiser.

               (iii) The two appraisers  shall select,  within the next ten (10)
          days,  a third  appraiser.  If the  appraisers  selected by Tenant and
          Landlord  are unable to reach an  agreement  as to the identity of the
          third  appraiser  within  said time  period,  the  appraiser  shall be
          determined  in  accordance  with  the  procedures  established  by the
          American  Arbitration  Association for the selection of an arbitrator,
          except that the appraiser selected must meet the qualifications for an
          appraiser as hereinafter set forth in (b)(iv) hereof.

               (iv) In order to qualify as an appraiser in  accordance  with the
          provisions of this paragraph,  the appraiser must qualify as an M.A.I.
          Appraiser,  be licensed as a real estate broker in accordance with the
          laws of the State of Florida,  which  license is in good  standing and
          has not been revoked,  and it must have substantial  experience in the
          sale and leasing of commercial and industrial  real estate in the area
          of Melbourne, Florida.

               (v) The third  appraiser  selected  shall  actually  conduct  the
          appraisal and determine the fair market  value.  In  determining  fair
          market  value,  the  appraiser  shall  appraise  the building as being
          vacant and available for occupancy by a third party.

               (vi) Both  Landlord and Tenant may submit to the  Appraiser  such
          information as they believe  appropriate for the  determination of the
          appraisal  price.  The  appraiser  may or may not  hold a  meeting  of
          Landlord's  and  Tenant's  representatives,  as such  appraiser  deems
          desirable;

               (vii)  Within  twenty  (20)  days  after  his  appointment,   the
          appraiser  shall  make his  determination  of the fair  market  value,
          determined in accordance with the foregoing  standards.  Said decision
          shall be final and binding and not subject to appeal.

               (viii) Unless written objection is made to the other party within
          five (5) days after the  selection of the  identity of the  appraiser,
          the objection to the  qualifications  of the appraiser shall be deemed
          waived.  If objections are made to the selection of an appraiser,  the
          party  whose  nominee it is will have ten (10) days in which to select
          the identity of a new appraiser.

               (ix) Tenant and  Landlord  shall pay the fees and expenses of the
          appraiser each has chosen.  The parties shall equally divide the fees,
          compensation and expenses of the third appraiser.

          c. Tenant shall  purchase the premises "as is" and Landlord  shall not
     be responsible for the condition of the building,  the infrastructure,  the
     land or the necessity for any repairs thereto, whether or not structural.

          d. The Demised Premises shall be conveyed, subject to title exceptions
     appearing  on  Exhibit  "E"  attached  hereto  and  incorporated  herein by
     reference.   Said  title  exceptions  include  a  reference  to  a  certain
     Declaration  of  Covenants,  Conditions  and  Restrictions  by and  between
     Henderson  Holding  Company and Elmer J. Krauss  Organization,  recorded of
     record in the Office of the Clerk of the  Circuit  Court in and for Brevard
     County, Florida, at Book #2652, Page #2739, et. seq., on December 2, 1985.

          e.  Title  shall be free  and  clear of all  liens,  encumbrances  and
     easements,  except those set forth in Exhibit "E" attached hereto. Landlord
     shall have the affirmative obligation to discharge before or at the time of
     settlement  all liens which can be discharged by the payment of money,  the
     total of which shall not be in excess of the net  proceeds of the sale.  If
     Landlord is unable to provide good and  marketable  title and such as would
     be insured by title  insurance  and at regular  rates,  subject only to the
     exceptions  set forth in Exhibit "E", then Tenant's sole remedy shall be to
     terminate its Option or to accept such title as Landlord is able to convey,
     without abatement of the Purchase Price.

          f. Settlement shall be made on said Purchase under subparagraph (a)(1)
     hereof during the last month of the fifth year of the Demised Premise, upon
     ten (10) days'  written  notice from Tenant to Landlord of under  paragraph
     (a)(2),  during the last month of the tenth year of the Demised Term, again
     settlement  being on ten (10) days' written notice from Tenant to Landlord.
     Settlement shall be held at the office of title insurer, and if there is no
     title insurer, at the office of seller.

          g. Time is of the essence of this  Agreement in exercising  the option
     and in consummating closing.

          h. At the time of  closing,  the  purchase  price  shall be payable by
     certified  check,  cashier's  check or wire transfer to Landlord's  account
     pursuant to the written instructions of Landlord.

          i. Documentary stamps on the deed and recording corrective instruments
     shall be paid by Landlord.  Documentary  stamps and  intangible  tax on the
     mortgage,  if any,  shall  be  paid by  Landlord.  Documentary  stamps  and
     intangible  tax on the mortgage,  if any,  shall be paid by Tenant.  Taxes,
     assessments,  rent,  interest,  insurance and other expenses and revenue of
     property  shall be pro rated  through day before  closing.  Cash at closing
     shall be increased or  decreased as may be required by  pro-rations.  Taxes
     shall be pro rated based on the current year's tax, with due allowance made
     for maximum allowance discount,  homestead and other exemptions. If closing
     occurs at a date when the current year's millage is not fixed,  and current
     year's  assessment  is available,  taxes will be pro-rated  based upon such
     assessment in a prior year's millage.  If current year's  assessment is not
     available,  then taxes will be  pro-rated  on the prior year's tax. Any tax
     pro ration  based on an  assessment  may,  at  request of either  Tenant or
     Landlord, be subsequently  readjusted upon receipt of tax bill on condition
     that a statement to that effect is in the closing statement.

          j. The deed shall be a special  warranty  deed which shall be recorded
     upon clearance of funds.

          k. If Tenant  fails or refuses to  consummate  closing on the purchase
     within the time specified,  and at Landlord's  option,  the Tenant shall be
     liable to Landlord for ten percent  (10%) of the  purchase  price as agreed
     upon liquidated  damages,  and in full  settlement of any claims  whereupon
     Tenant and Landlord shall be relieved of all further  obligations under the
     exercised  option to  purchase;  or Landlord,  at  Landlord's  option,  may
     proceed in equity to enforce  Landlord's  rights under this  Agreement  for
     consummation  of the  exercise to  Purchase.  If for any reason  other than
     failure of Landlord to make  Landlord's  title  marketable  after  diligent
     effort, Landlord fails or neglects or refuses to perform this Contract, the
     Tenant may seek specific performance, which shall be Tenant's only remedy.

          l. From the time of exercise of the Option to Purchase  until the time
     of Closing, Tenant on the Lease for the property to be purchased may not be
     in default in any of the  provisions of its Lease.  In the event the Option
     to Purchase is  rescinded  due to Tenant  default in its Lease,  Seller may
     retain the deposit  money as liquidated  damages,  and Tenant shall have no
     further options to purchase the Demised Premises.

     IN WITNESS  WHEREOF,  the parties  hereto have  executed  this Rider to the
Lease the day and year first above written.


                                          LANDLORD:

          Term.

     4. NET LEASE.  It is the intent of the  parties  hereto  that this is a net
lease,  and that all  costs of  ownership,  maintenance  and use of the  Demised

     5. IMPROVEMENT OF DEMISED PREMISES.

          (a)  CONSTRUCTION  OF THE BUILDING.  After execution of this Lease and
initialing   of  the  final   plans  and   specifications   ("Final   Plans  and
Specifications")  for the  Building,  which Final Plans and  Specifications  are

and  quality  when  and if any  specified  material  shall  not be  readily  and
reasonably available,  and (2) to make changes necessitated by conditions met in
the course of construction,  provided that Tenant's approval of any change shall
first be obtained (which approval shall not be unreasonably withheld) so long as
there shall be general  conformity with Tenant's  Improvement Plans and Tenant's
intended use of the Demised  Premises and which approval must be given or denied
(with reasons stated in the case of denial) within  forty-eight (48) hours after
request or approval shall be conclusively deemed to have been given.

     6. INABILITY TO GIVE POSSESSION.

          (a) EXCUSABLE  DELAYS.  Landlord shall not be liable to Tenant for any
damages  caused by  Landlord's  inability to deliver  possession  of the Demised
Premises  to  Tenant on the  Commencement  Date,  as a result  of causes  beyond
Landlord's reasonable control,  including,  but not limited to, delays caused by
Tenant's  acts  or by  strikes,  lockouts,  labor  disputes,  inclement  weather
(including the day(s) following  inclement  weather when contraction work cannot
proceed  due  to  saturation  of  soils  or  other  unsatisfactory  conditions),
inability to procure materials, failure of power, restrictive governmental rules
and regulations, riots, insurrections or war ("Excusable Delays").

          (b) DELIVERY OF DEMISED  PREMISES.  If the Landlord shall be unable to
give possession of the Demised  Premises within nine (9) months of receiving the
building  permit  from the City of  Melbourne,  exclusive  of  Excusable  Delays
("Completion Date") or because a certificate of occupancy has not been procured,
Landlord  shall not be  subject  to any  liability  for such  inability  to give
possession  under such  circumstances.  The  payment of rent shall not  commence
until the  Commencement  Date. The failure to give  possession on the Completion
Date shall not affect the  validity of this Lease or the  obligations  of Tenant
hereunder or extend the Demised Terms, provided,  however, in the event Landlord
is unable to give possession on or before the tenth (10th) month after receiving
the building  permit from the township  (exclusive  of Excusable  Delays),  then
Tenant  shall  have the  option  of  declaring  the Lease  terminated  by giving
Landlord written notification  thereof, by registered mail, within two (2) weeks
of the first day of said tenth (10th) month.

     7. ADDITIONAL RENT.

          (a) BREACH. Tenant agrees to pay as rent in addition to the Basic Rent
any and all sums  which may  become  due by reason of the  failure  of Tenant to
comply with all of the  covenants of this Lease and any and all  damages,  costs
and expenses,  including attorney's fees, which the Landlord may suffer or incur
by reason of such default,  and also any and all damages to the Demised Premises
caused by any act or neglect of the Tenant.

          (b)  TAXES,  ASSESSMENTS,  ETC.  Tenant  will  duly  promptly  pay  as
additional rent to Landlord, as the same shall become due and payable and before
they become  delinquent,  all taxes,  rates,  assessments and other governmental
charges,  and charges of every kind and nature whatsoever;  nonrecurring as well
as  recurring,  special  or  extraordinary  as well as  ordinary,  foreseen  and
unforeseen,  and each and every installment  thereof,  which shall or may during
the term of the Lease be levied,  assessed or imposed, or become due and payable
or  become  liens  upon,  or arise in  connection  with  the use,  occupancy  or
possession  of, or any  interest  in, the Demised  Premises,  or upon the rents,
issues,  income and profits therefrom so as to prevent the same from becoming or
being an  enforceable  lien or claim  against the  property  or the  interest of
Landlord  ("Expenses").  Landlord  shall  apply  such  payment  by Tenant to the
payment of such Expenses, but in no event shall Landlord be required to pay such
Expenses early or during discount periods.  Such Expenses shall include all real
estate taxes,  assessments,  water and sewer charges which may become liens upon
the Demised  Premises or any part thereof.  If Landlord  requests  Tenant to pay
such  Expenses  other  than to  Landlord,  Tenant  will  furnish  or cause to be
furnished to Landlord not less than fifteen (15) days prior to the date on which
payment of the same would become delinquent,  or subject to penalty or interest,
receipts or other evidence  satisfactory  to Landlord of the payment of all such
Expenses.  If Landlord requests in writing,  Tenant shall pay to Landlord, or as
Landlord may direct,  such Expenses in advance in  installments as estimated and
determined by Landlord, and deposited with Landlord, or as directed by Landlord,
for  payment of all such  Expenses  when the same may  become  due and  payable.
Notwithstanding  the  foregoing,  Tenant  shall  not be  responsible  for  gross
receipts or other  income  taxes  incurred  by  Landlord  on the rents  received
hereunder  unless it is imposed in lieu of  another  charge for which  Tenant is
responsible hereunder.

          If the Tenant deems  excessive or illegal any such Expenses,  with the
written consent of the Landlord,  the tenant may make payment under protest. Any
contest,  whether  before  or  after  payment,  may be made  in the  name of the
Landlord or the Tenant or both,  with the written  consent of the  Landlord.  If
requested by Tenant,  Landlord may, but shall not be required to  participate in
any such  contest,  but the Tenant  shall be  entitled to any refund of any such
Expenses,  and any penalty or interest  thereon  which may have been paid by the
Tenant,  but all costs in  connection  with such  contest  shall be borne by the
Tenant.

          In case of  failure of the  Tenant to make any of the  payments  to be
made by Tenant for such  Expenses,  the Landlord  may, but shall not be required
to, pay the amount of same,  with  penalty and  interest  thereon,  if any.  The
amount so paid by the Landlord,  with interest  thereon from the date of payment
thereof  by the  Landlord,  shall  be  added  to and  become  a part of the next
installment of rent.

          If at any time  during the term of this Lease the  methods of taxation
prevailing  at the  commencement  of the term hereof shall be altered so that in
lieu of or as a supplement  to or a substitute  for the whole or any part of the
real estate  taxes or  assessments  now  levied,  assessed or imposed (1) a tax,
assessment, levy, imposition or charge, wholly or partially as a capital levy or
otherwise,  on the  rents  received  therefrom  or (2) a tax,  assessment,  levy
(including but not limited to any municipal,  state or federal levy), imposition
or charge measured by or based in whole or in part upon the premises and imposed
upon the Landlord,  or (3) a license fee measured by the rent payable under this
Lease, then all such taxes,  assessments,  levies or impositions and charges, or
the part  thereof so  measured  or based  shall be deemed to be  included in the
general real estate taxes and assessments  payable by the Tenant pursuant hereto
to the extent  that such taxes,  assessments,  levies,  impositions  and charges
would be payable if the premises were the only property of the Landlord  subject
thereto,  and the Tenant shall pay and discharge the same as herein  provided in
respect of the payment of general real estate taxes and assessments.

          (c) INSURANCE.  Landlord shall keep all buildings and improvements now
or hereafter erected upon the Demised Premises,  together with Chattels therein,
insured for the benefit of Landlord  against  loss by fire and other  casualties
and hazards usually covered by extended coverage insurance in an amount not less
than the replacement  value of the Demised Premises  (excluding  foundations and
other parts below the surface of the lowest floor),  as determined not more than
once annually by an appraiser or rating bureau satisfactory to Landlord.  Tenant
agrees  that  it  will,  throughout  the  Demised  Term,  pay and  discharge  as
additional  rent, the cost incurred by Landlord in insuring the Demised Premises
as above stated.  Insurance  premiums at the beginning and end of the term shall
be  apportioned.  It is expressly  understood  and agreed that if for any reason
attributable  to Tenant it shall be impossible  to obtain Fire  insurance on the
building and  improvements on the Demised  Premises in an amount and in the form
and with fire insurance companies acceptable to the Landlord,  the Landlord may,
if the Landlord elects,  (a) terminate this Lease and the term thereof on giving
to the Tenant fifteen (15) days' notice in writing of Landlord's intention to do
so and upon the giving of such  notice this lease and the terms  thereof,  shall
terminate  and  come to an end;  (b)  compute  the  additional  costs  for  such
insurance over and above the standard cost as if the condition  attributable  to
Tenant did not exist and Tenant shall be obligated to pay all of such additional
cost.

          Tenant shall also provide at its sole cost and expense,  any insurance
on improvements  made to or inside the Demised  Premises by Tenant.  Such policy
shall name as insured  Landlord and Tenant,  as their  interests  may appear and
shall name  Landlord's  first  mortgagee,  if any, as mortgagee.  A copy of such
policy shall be furnished to Landlord and Landlord's first mortgagee.

          Tenant  at its own cost and  expense  will  provide  and keep in force
during the Demised Term of this Lease  commercial  general  liability  insurance
covering  at  lease  the  hazards  of  "premises-operations",   "elevators"  (if
applicable) and "independent contractors" in which Landlord shall be included as
a named  insured,  in such  other  limits of  liability  as may be  required  by
Landlord   from  time  to  time,   but  not  less  than  One   Million   Dollars
($1,000,000.00)  combined  single  limit,  with a deductible  not to exceed Five
Thousand  Dollars  ($5,000.00).  Such insurance shall cover not only the Demised
Premises but shall also include all elevators,  hoists, hallways,  entranceways,
stairs or any other common areas  (exterior or  interior),  streets,  driveways,
alleys, lawns, parking and loading areas, sidewalks and curbs adjacent thereto.

          All such  policies  shall  contain  provision  for  notice to the said
Landlord not less than ten (10) days in advance of any  cancellation or material
change of such policy. In case of failure of the Tenant to make premium payments
when due,  the Landlord  may pay the amount of any such  premiums,  which amount
with interest thereon from the date of payment by Landlord shall be added to and
become part of the next installment of rent.

          Copies of renewal policies or certificates for any insurance  required
under this  Paragraph  shall be deposited  by Tenant with  Landlord at least ten
(10) days prior to the expiration of existing  policies,  and upon failure to do
so Landlord may immediately  purchase,  for the account of Tenant, the necessary
insurance from any reputable  insurance  company  without notice to Tenant,  and
Tenant shall  reimburse  Landlord  for cost  thereof  within ten (10) days after
demand.

          All insurance required hereunder shall be issues by companies licensed
to do business in Florida and  acceptable  to  Landlord.  Tenant  shall have the
right to carry the insurance provided for in this Paragraph,  or any portions of
such insurance under a blanket or comprehensive all-risks policy.

          d.  UTILITIES.  Tenant  further  agrees to pay as additional  rent all
charges for water, sewer, gas, oil, electricity,  light, heat, power,  telephone
or other utility used by Tenant at the Demise  Premises during the Demised Term.
All charges for repair of the utility meter(s) on the Demised Premises,  whether
such repairs are made necessary by ordinary wear and tear, freezing,  hot water,
accident,  or other causes,  shall be payable by Tenant as  additional  rent and
shall be paid immediately when the same become due.

          e. MISCELLANEOUS. Tenant agrees to pay as Additional Rent its pro-rata
share of all Center charges,  as set forth in Paragraph 35 hereof,  for: signage
repairs,  exterior  janitorial  service,  grounds  maintenance and  landscaping,
parking lot maintenance,  fences and site lighting.  Landlord shall perform,  at
Tenant's cost and expense,  the grounds  maintenance,  landscaping,  parking lot
maintenance and site lighting for the Demised  Premises and bill Tenant the cost
for same as Additional Rent.

          8. TIME, PLACE AND WITHHOLDING OF PAYMENT.  Unless provided  otherwise
herein,  all Basic Rent and additional  rent shall be payable in advance without
prior  notice or demand and without any set off or deduction  whatsoever  at the
office of Landlord  (or at such other  place as  Landlord  may from time to time
designate by notice in writing) and at the times provided for the payment of the
Basic Rent. Under no circumstances will Tenant be permitted to withhold rent for
any reason.

them relate to structural  changes or  requirements  of whatever  nature,  or to
changes  or  requirements  incident  thereto,  or as the  result  of the  use or
occupation  thereof by Tenant,  and the Tenant  shall pay all costs and expenses
incidental  to such  compliance,  and  shall  indemnify  and save  harmless  the
Landlord  from all  expense,  and  damages  by  reason of any  notices,  orders,
violations or penalties  filed  against or imposed upon the Demised  Premises or

comply with this covenant.  Tenant  further agrees to keep the Demised  Premises
clean and free from all ashes,  dirt and other refuse matter;  replace all glass

Landlord,  Tenant  shall vacate or decide at any time during the Demised Term to
vacate the herein Demised Premises prior to the expiration of this Lease, or any
renewal  hereof,  Tenant  will not cause or allow any other  agent to  represent
Tenant in any  subletting  or  reletting of the Demised  Premises  other than an
agent  approved by the Landlord,  and that should Tenant do so, or attempt to do
so,  the  Landlord,  may  remove  any  signs  that may be placed on or about the
Demised  Premises by such other agent  without any  liability  to landlord or to
said agent, the Tenant assuming all responsibility for such action.

          10. NEGATIVE COVENANTS OF TENANT.  Tenant covenants and agrees that he
will do none of the following  things without the consent in writing of Landlord
first had and obtained:

of the breach of this  covenant  (in  addition  to all other  remedies  given to
Landlord in case of the breach of any  conditions  or  covenants  of this Lease)
Landlord  shall have the  privilege of removing  said stand,  booth,  show case,

the termination of this Lease,  unless Landlord shall,  prior to the termination
of this Lease,  have given written notice to Tenant to remove the same, in which
event  Tenant will remove such  alterations,  improvements,  and  additions  and

the right to do the  following  things  and  matters  in and  about the  Demised
Premises:

          (a)  INSPECTION.  At all  reasonable  times  by  himself  or his  duly
authorized  agent to go upon and  inspect the  Demised  Premises  and every part
thereof, and/or at his option to make repairs,  alterations and additions to the
Demised  Premises  or the  building  of which the  Demised  Premises  is a part.
Excepting  emergencies,  Landlord  shall give Tenant 24 hours'  prior  notice of
inspection,  and Tenant  shall  have the right to escort  Landlord  during  such
inspection, if Tenant so desires.

          (b) RULES AND REGULATIONS.  At any time or times and from time to time
to make such  reasonable  rules and regulations as in his judgment may from time
to time be  necessary  for the  safety,  care  and  cleanliness  of the  Demised
Premises,  and for the  preservation  of  good  order  herein.  Such  rules  and
regulations  shall, when notice thereof is given to Tenant,  form a part of this
Lease.

          (d)  DISCONTINUANCE  OF  FACILITIES  AND  SERVICES.  The  Landlord may
discontinue all facilities  furnished and services  rendered,  or any of them by
Landlord,  not expressly  covenanted for herein,  it being  understood that they
constitute no part of the consideration for this Lease.

     12.  RESPONSIBILITY  OF  TENANT.   Landlord  shall  not  in  any  event  be
responsible,  and the Tenant hereby specifically assumes  responsibility for any
personal or bodily injury or death of any persons (including employees of Tenant
and Landlord) and damage, destruction, or loss of use of any property, including
the  Demised  Premises  (except  as  specifically   provided  otherwise  herein)
occasioned by any event  happening on or about the Demised  Premises,  hallways,
entranceways,   stairs  or  any  other  common  areas  (exterior  or  interior),
elevators, hoists, streets, driveways, parking and loading areas, alleys, lawns,
sidewalks and curbs adjacent thereto  including those resulting from any work in
connection with any alterations, changes, new construction or demolition, except
if same results solely from the negligence of Landlord, its agents, servants, or
employees.  Tenant is  subrogated  to any rights of  Landlord  against any other
parties  in  connection  therewith.  Tenant  shall  defend,  indemnify  and hold
harmless Landlord from and against any and all claims,  demands, suits, damages,
liability and costs (including  counsel fees and expenses)  arising out of or in
any manner connected with any act or omission, negligent or otherwise of Tenant,
third persons, or any of their agents,  servants or employees which arise out of
or are in any way connected  with the  erection,  maintenance,  use,  operation,
existence or occupation of the Demised Premises, hallways, entranceways,  stairs
or any other common areas (exterior or interior),  elevators,  hoists,  streets,
driveways,  parking  and  loading  areas,  alleys,  lawns,  sidewalks  and curbs
adjacent  thereto unless due solely to the  negligence of Landlord,  its agents,
servants or employees.

          The Landlord  shall  promptly  notify the Tenant of any claim asserted
against the Landlord on account of any such injury or claimed  injury to persons
or party and shall promptly deliver to the Tenant the original or a true copy of
any summons or other  process,  pleading  or notice  issues in any suit or other
proceeding or assert or enforce any such claim.  The Tenant shall have the right
to defend any such suit with  attorneys  of its own  selection  and the Landlord
shall have the right, if it sees fit, to participate in such defense.

          Tenant further shall defend, indemnify and hold harmless Landlord from
claims,  demands,  suits, liability for damages for personal or bodily injury or
death of any persons or damage or destruction of any property (including loss of
use thereof) caused by or in any manner arising out of any breach,  violation of
nonperformance by Tenant of any covenant, term or provision of this Lease.

     13. DAMAGE TO DEMISED PREMISES.

          (a) In the event that the Demised Premises is totally  destroyed or so
damaged by fire or other  casualty not occurring  through fault or negligence of
the Tenant or those employed by or acting for him, that, in Landlord's judgment,
the same cannot be repaired or restored  within one hundred  eighty  (180) days,
this Lease shall absolutely cease and determine,  and the rent shall abate as of
the date of casualty  for the balance of the term.  If  Landlord  cannot  locate
alternate  space for  Tenant to  continue  operation  during  the  course of the
repairs,  then Tenant shall have the right to terminate this Lease within thirty
(30) days.

          (b) If the damage  caused as above be only  partial  and such that the
Demised Premises, in Landlord's judgment, can be restored within the time period
and under the conditions as provided in Subparagraph  13(a) above,  the Landlord
may, at its option,  restore the same (excluding fixtures and improvements owned
by Tenant) with  reasonable  promptness,  reserving  the right to cater upon the
Demised Premises for that purpose. The Landlord also reserves the right to enter
upon the Demised Premises whenever  necessary to repair damage caused by fire or
other  casualty to the  building of which the Demised  Premises is a part,  even
though  the effect of such entry be to render  the  Demised  Premises  or a part
thereof  untenantable.  In  either  event  the  rent  shall be  apportioned  and
suspended during the time the Landlord is in possession, taking into account the
portion of the Demised  Premises  rendered  untenantable and the duration of the
Landlord's possession.  If a dispute arises as the amount of rent due under this
clause, Tenant agrees to pay the full amount claimed by Landlord.  Tenant shall,
however, have the right to proceed by law to recover the excess payment, if any.

          (c) Landlord  shall make such election to repair the Demised  Premises
or terminate  this Lease by giving  notice  thereof to Tenant within thirty (30)
days from the day Landlord  received  notice that the Demised  Premises had been
destroyed or damaged by fire or other casualty.

          (d)  Notwithstanding the fact that Landlord may have elected to repair
the Demised  Premises  within said  thirty  (30) day  period,  if the  mortgagee
chooses to  accelerate  the mortgage due to damage by fire or other  casualty to
the Demised  Premises or the  building of which the Demised  Premises is a part,
Landlord  shall have the right to rescind  and/or cancel said election to repair
and  shall  have the right to elect not to repair  the  damaged  to the  Demised
Premises or the building of which the Demised Premises is a part,  provided said
notification  of election  not to repair is given to Tenant  within  thirty (30)
days after date of the receipt of said notice of acceleration.

          (e) Landlord shall not be liable for any damage, compensation or claim
by reason of inconvenience or annoyance  arising from the necessity of repairing
any  portion  of  the  building,  the  interruption  in the  use of the  Demised
Premises,  or the  termination of this Lease by reason of the destruction of the
Demised Premises.

     14. MISCELLANEOUS AGREEMENTS AND CONDITIONS.

          (a)  NON-WAIVER BY LANDLORD OR TENANT.  The failure of the Landlord or
Tenant to insist upon strict  performance  of any of the covenants or conditions
to this lease,  or to exercise  any option  herein  conferred in any one or more
instances,  shall not be construed as a waiver or relinquishment  for the future
of any such covenants or conditions of this Lease or option,  but the same shall
be and remain in full force and effect.

          (b)  ACCORD  AND  SATISFACTION.  No  payment  by Tenant or  receipt by
Landlord of a lesser  amount than the monthly  rent herein  stipulated  shall be
deemed to be other than on account of the earliest  stipulated  rent,  nor shall
any endorsement or statement on any check or any letter  accompanying  any check
or payment as rent be deemed an accord and satisfaction, and Landlord may accept
such check or payment  without  prejudice  to  Landlord's  right to recover  the
balance of such rent or pursue any other remedy herein.

          (c)  JURISDICTION  AND  LAW.  Tenant  hereby  subjects  itself  to the
jurisdiction of the Court of Brevard County,  Florida.  The laws of the State of
Florida shall be applicable to this lease and any interpretations thereof.

          (d) The Landlord has let the Demised  Premises,  with the Building and
Improvements as required by Paragraph 5, and without any  representations on the
part of Landlord, his officers, employees, servants and/or agents.

     15. REMEDIES OF LANDLORD. If the Tenant:

          (a) Does not pay  within  ten  (10)  days  after it is due any and all
installments  of rent  and/or  any other  charge  or  payment  herein  reserved,
included,  or agreed to be treated or collected as rent and/or any other charge,
expense, or cost herein agreed to be paid by the Landlord; or

          (b) Violates or fails to perform or otherwise  breaks any non-monetary
covenant or agreement  herein  contained  which is not  corrected in  compliance
within thirty (30) days after the notice; or

          (c) Vacates  the Demised  Premises or removes or attempts to remove or
manifests an intention to remove any goods or property therefrom  otherwise than
in the  ordinary  and usual  course of business  without  having  first paid and
satisfied the Landlord in full for all rent and other charges then due; or

          (d) Files or has filed  against it (and if against  not  dismissed  in
thirty (30) days) a petition under Title 11, United States Code, Bankruptcy,  as
now or hereafter  amended or supplemented,  whether under Chapter 7, 11 or 13 of
the aforesaid  Bankruptcy Code; or if there is the commencement of any action or
proceeding  under state or federal law for the dissolution or liquidation of the
Tenant in connection with bankruptcy or other insolvency,  whether instituted by
or against (and if against not  dismissed in thirty (30) days) the Tenant or for
the  appointment  of a receiver  or trustee of all or  substantially  all of the
property of the Tenant;  or if there is the taking of possession of the property
of the  Tenant by any  governmental  officer  or agency  pursuant  to  statutory
authority for the dissolution, rehabilitation,  reorganization or liquidation of
the  Tenant;  or if there is the making by the Tenant of an  assignment  for the
benefit of creditors;

          Then and in any of said  events,  there shall be deemed to be a breach
of this Lease, and thereupon Landlord shall have the following rights:

          1.  To  accelerate  the  whole  or any  part  of the  Basic  Rent  and
additional rent (sometimes  collectively referred to herein as "Rent") and other
charges, payments, costs and expenses herein agreed to be paid by Tenant for the
entire unexpired balance of the term of this Lease, and any Rent, other charges,
payment,  costs and expenses if so accelerated shall, in addition to any and all
installments  of Rent  already due and payable and in arrears,  and/or any other
charge,  expense or cost herein agreed to be paid by Tenant which may be due and
payable  and in  arrears,  be  deemed  due and  payable  as if, by the terms and
provisions of this Lease,  such  accelerated  Rent and other charges,  payments,
costs and expenses were on that date payable in advance, provided, however, that
Landlord agrees it will not exercise this remedy unless Tenant is in arrears for
a total of three (3) monthly installments of Base Rent under the Lease.

          2. To re-enter the Demised Premises and remove all persons  therefrom,
either by summary dispossess proceedings or by any suitable action or proceeding
at law, without being liable to indictment, prosecution or damages therefor, and
repossess  and  enjoy  the  Demised  Premises,  together  with all  alterations,
fixtures and signs. Upon recovering possession of the Demised Premises by reason
of or based  upon or arising  out of a default  on the part of Tenant,  Landlord
may, at Landlord's option,  either terminate this Lease or make such alterations
and repairs as may be necessary in order to relet the Demised Premises and relet
the Demised premises or any part or parts thereof,  either in Landlord's name or
otherwise,  for a term or terms which may at  Landlord's  option be less than or
exceed the period which would otherwise have constituted the balance of the term
of this Lease and at such rent or rents and upon such other terms and conditions
as in  Landlord's  sole  discretion  may seem  advisable  and to such  person or
persons as may in Landlord's  discretion seem best; upon each such reletting all
rents received by Landlord from such reletting  shall be applied:  first, to the
payment  of any  indebtedness  other  than  rent due  hereunder  from  tenant to
Landlord;  second,  to the payment of any costs and expenses of such  reletting,
including  brokerage fees and attorney's fees and all costs of such  alterations
and repairs;  third,  to the payment of Rent due and unpaid  hereunder;  and the
residue, if any, shall be held by Landlord and applied in payment of future Rent
as it may become due and payable  hereunder.  If such rentals received from such
reletting  during any month shall be less than that to be paid during that month
by Tenant  hereunder,  Tenant shall pay any such  deficiency  to Landlord.  Such
deficiency  shall be  calculated  and paid  monthly.  No such re-entry or taking
possession  of  the  Demised  Premises  or  the  making  of  alterations  and/or
improvements  thereto or the reletting thereof shall be construed as an election
on the part of Landlord to terminate  this Lease unless  written  notice of such
intention  be given to Tenant.  Landlord  shall in no event be liable in any way
whatsoever  for failure to relet the Demised  Premises or, in the event that the
Demised  Premises or any part or parts thereof are relet, for failure to collect
the  rent  thereof  under  such  reletting.  Tenant,  for  Tenant  and  Tenant's
successors and assigns,  hereby irrevocably constitutes and appoints Landlord as
Tenant's and  Landlord's  agent to collect the rents due and to become due under
all subleases of the Demised  Premises or any parts  thereof  without in any way
affecting Tenant's obligation to pay any unpaid balance of Rent due or to become
due hereunder.  Notwithstanding any such reletting without termination, Landlord
may at any time  thereafter  elect to  terminate  this  Lease for such  previous
breach.

          (4) To terminate  this Lease and the term hereby  created  without any
right on the part of Tenant to waive the forfeiture by payment of any sum due or
by other  performance  of any  condition,  term or  covenant  broken.  Whereupon
Landlord  shall be  entitled  to  recover,  in  addition to any and all sums and
damages for violation of Tenant's obligations hereunder in existence at the time
of such  termination,  damages for  Tenant's  default in an amount  equal to the
greater of (i) amount of the Rent  reserved for the balance of the Demised Term,
as well as all other charges,  payments,  costs and expenses herein agreed to be
paid by Tenant,  all  discounted  at the rate of nine  percent (9%) per annum to
their then present worth, less the fair rental value of the Demised Premises for
the remainder of said term, also discounted at the rate of nine percent (9%) per
annum to its then  present  worth or (ii) three (3) months'  rent,  all of which
amount  shall  be  immediately  due and  payable  from  Tenant  to  Landlord  as
liquidated damages.

     16.  RIGHT OF  INJUNCTIVE  RELIEF.  In the event of a breach or  threatened
breach by Tenant of any of the covenants or provisions  hereof,  Landlord  shall
have the right of injunction  and the right to invoke any remedy  allowed at law
or in equity,  as if re-entry,  summary  proceedings and other remedies were not
herein provided for.

     17.  RIGHTS NOT  EXCLUSIVE.  No right or remedy  herein  conferred  upon or
reserved to Landlord  is intended to be  exclusive  of any other right or remedy
herein or by law provided but each shall be cumulative  and in addition to every
other right or remedy  given  herein or now or  hereafter  existing at law or in
equity or by statute.

     18. WAIVERS BY TENANT. Tenant expressly waives the right to delay execution
on any real  estate  that may be levied  upon to collect  any  amount  which may
become  due under the terms and  conditions  of this Lease and any right to have
the same appraised. Tenant agrees that said real estate may be sold on a writ of
execution or other process.

     19.  CALCULATIONS  OF  AMOUNTS  DUE.  For the  purpose of  calculating  the
accelerated  Rent payable under paragraph (1) of Paragraph 15(d) of this Article
and the  "Rent  reserved  for the  balance  of the  term" of this  Lease for the
purposes of Paragraph (4) of Paragraph 15(d) of this Article, the amount payable
as Tenant's share of real estate taxes,  Tenant's share of the cost of insurance
on the Demised Premises and Tenant's share of common area  maintenance  expenses
and any other charges for which Tenant is responsible  hereunder for the balance
of the term  hereof  shall be equal  to the sum of the  highest  amount  paid or
payable  by  Tenant  in any  calendar  year  for  each  of the  foregoing  items
multiplied by the number of calendar years  (including  any fractional  calendar
year) remaining in the term of this Lease.

     20. RIGHT OF ASSIGNEE OF LANDLORD.  The right to pursue the remedies herein
provided against Tenant and to enforce all of the other provisions of this Lease
may, at the option of any  assignee of this Lease,  be exercised by any assignee
of the Landlord's  right,  title and interest in this Lease in his, her or their
own name,  any  statute,  rule of court,  custom,  or practice  to the  contrary
notwithstanding.

     21. REMEDIES CUMULATIVE. All of the remedies hereinbefore given to Landlord
and all rights and remedies  given to it by law and equity  shall be  cumulative
and concurrent.  No termination of this Lease or the taking or recovering of the
Demised  Premises  shall  deprive  Landlord  of any of its  remedies  or actions
against  Tenant  for rent or sums  due at the time or  which,  under  the  terms
hereof, would in the future become due as if there has been no termination;  nor
shall the bringing of any action for rent or breach of  covenant,  or the resort
to any other remedy  herein  provided for the recovery of rent be construed as a
waiver of the right to obtain possession of the premises.

     22. CONDEMNATION.  If at any time during the Demised Term or any renewal or
extension  thereof the Demised  Premises,  or any portion  thereof,  be lawfully
condemned or conveyed in lieu of  condemnation,  the Landlord  shall be entitled
to, and shall  receive  the award or  payment  therefor,  and the  Tenant  shall
assign,  and does  hereby  assign and  transfer  to the  Landlord  such award or
payment  as may be made  therefor,  and in no event and  under no  circumstances
shall the  Tenant be  entitled  to receive or retain any award or payment of any
part thereof. This Lease shall, as to the part so taken terminate as of the date
title shall vest in the  condemnor,  and rent shall abate in  proportion  to the
square feet of the leased space taken or condemned.

     23. EXECUTION OF ESTOPPEL CERTIFICATE.  At any time, and from time to time,
upon the  written  request of  Landlord or any first  mortgagee,  Tenant  within
twenty  (20) days of the date of such  written  request  agrees to  execute  and
deliver to Landlord  and/or such first  mortgagee,  without charge and in a form
satisfactory  to  Landlord  and/or  such  mortgagee,  a written  statement:  (a)
ratifying this Lease; (b) confirming the commencement and expiration date of the
term of this Lease and the minimum  annual rental rate payable  during the lease
term; (c) certifying  that Tenant is in occupancy of the Demised  Premises,  and
that the Lease is in full force and effect and has not been modified,  assigned,
supplemented  or  amended  except  by such  writing  as  shall  be  stated;  (d)
certifying  that all conditions and agreements  under this Lease to be satisfied
or performed by Landlord have been  satisfied  and performed  except as shall be
stated; (e) certifying that Landlord is not in default under the Lease and there
are no defenses or offsets  against the enforcement of this Lease by Landlord or
stating the defaults and/or defenses claimed by Tenant;  (f) reciting the amount
of advance rent, if any, paid by Tenant and the date to which such rent has been
paid and, if requested by Landlord and/or Mortgagee,  agreeing that Tenant shall
not pay rent to Landlord  more than thirty days in  advance;  (g)  reciting  the
amount of security  deposited with Landlord,  if any; (h) certifying that Tenant
has no option or right of first  refusal to  purchase  the  Demised  Premises or
option to extend  the term of the Lease  (unless  specifically  set froth to the
contrary in the Lease); (i) if requested by Landlord and/or Mortgagee,  agreeing
that the Lease will not be  modified  without the prior  written  consent of the
Mortgagee;  (j)  certifying  that tenant  will not  generate,  store,  handle or
otherwise deal with any amount of any hazardous substances or hazardous waste(as
defined in federal,  state and local law) in or about the Demised  Premises,  in
excess of those levels or quantities  specified  for  regulatory  purposes;  (k)
agreeing, if requested by Mortgagee, that Tenant will give Mortgagee such notice
of any default by Landlord and reasonable  opportunity to cure such default, not
in excess of thirty (30) days,  unless the default  cannot be cured  within said
time,  before  exercising  Tenant's  remedies under the Lease; and (l) any other
information which Landlord or the mortgagee shall require.

     24.  FAILURE  TO EXECUTE  ESTOPPEL  CERTIFICATE.  The  failure of Tenant to
execute,  acknowledge  and  deliver to  Landlord  and/or any first  mortgagee  a
statement in  accordance  with the  provisions  of Paragraph 23 above within the
said twenty (20) day period shall constitute  acknowledgment by Tenant which may
be relied  upon by any person  holding or  intending  to  acquire  any  interest
whatsoever  in the  Demised  Premises  that this  Lease  has not been  assigned,
amended,  changed,  or modified,  is in full force and effect and that the Basic
Rent and additional rent have been duly and fully paid not beyond the respective
due dates  immediately  preceding the date of the request for such statement and
shall  constitute as to any persons entitled to rely on such statements a waiver
of any defaults by Landlord or defenses or offsets  against the  enforcement  of
this Lease by Landlord which may exist prior to the date of the written request,
and  Landlord at its option,  may treat such  failure as a  deliberate  event of
default.

     25. SUBORDINATION AND ATTORNMENT. Tenant agrees:

          (a) that,  except as hereinafter  provided,  this Lease is, and all of
Tenant's  rights  hereunder are and shall always be, subject and  subordinate to
any first mortgage ("First Mortgage"); and

          (b) That if the holder of any such First Mortgage  ("Mortgagee") or if
the  purchaser  at any  foreclosure  sale or at any  sale  under a power of sale
contained  in any  Mortgage  shall at its sole  option so  request,  Tenant will
attorn to, and  recognize  such  mortgagee or  purchaser,  as the case may be as
Landlord  under this Lease for the balance  then  remaining  of the term of this
Lease, subject to all terms of this Lease; and

          (c) That the  aforesaid  provisions  shall  be  self-operative  and no
further  instrument or document shall be necessary  unless  required by any such
First Mortgagee or purchaser. Notwithstanding anything to the contrary set forth
above,  and First  Mortgagee  may at any time  subordinate  its Mortgage to this
Lease,  without Tenant's consent,  by notice in writing to Tenant, and thereupon
this  Lease  shall be  deemed  prior to such  Mortgage  without  regard to their
respective dates of execution,  delivery and/or recording and in that event such
First  Mortgage  shall have the same rights with respect to this Lease as though
this Lease had been  executed and a  memorandum  thereof  recorded  prior to the
execution,  delivery and  recording of the Mortgage and as though this Lease had
been assigned to such First Mortgagee. Should Landlord or any First Mortgagee or
purchaser desire  confirmation of either such  subordination or such attornment,
as the case may be,  Tenant upon written  request,  and from time to time,  will
execute and deliver  without charge and in form  satisfactory  to Landlord,  the
First  Mortgagee or the purchaser all instruments  and/or  documents that may be
requested to  acknowledge  such  subordination  and/or  agreement to attorn,  in
recordable form.

          (d) Landlord  agrees that it shall  procure from the mortgagee who has
agreed  to  provide a  commitment  for a  five-year  permanent  mortgage  on the
Property  the  mortgagee's  consent  to a  non-disturbance  agreement,  in  form
reasonably  satisfactory  to Tenant,  which approval  shall not be  unreasonably
withheld.  If Landlord is unable to produce said  agreement  from such mortgagee
prior to the closing of the  construction  mortgage,  then Tenant shall have the
right to terminate  this  Agreement  within five (5) days after  receipt of such
advice from Landlord.

          Landlord further agrees that it shall use reasonable efforts to obtain
a similar agreement from any successor first mortgagee.

     26. FAILURE TO EXECUTE INSTRUMENTS AND DOCUMENTS. In the event Tenant fails
to execute  and  deliver  the  instruments  and  documents  as  provided  for in
Paragraphs  23 and 25 within  twenty  (20) days  after  request  in  writing  by
Landlord or such First  Mortgagee or purchaser,  as the case may be, Tenant does
hereby  make,  constitute  and  appoint  Landlord  or such  First  Mortgagee  or
purchaser,  as the case may be, as  Tenant's  attorney-in-fact  and in its name,
place and stead to do so, or  Landlord  may treat such  failure as a  deliberate
event of default.  The  aforesaid  power of attorney is given as coupled with an
interest and is irrevocable.

     27. QUIET ENJOYMENT;  EVICTION BY FORECLOSURE.  Tenant,  on paying the rent
reserved,  and performing all the covenants and conditions hereof,  shall at all
times during the Demised Term,  peaceably  and quietly have,  hold and enjoy the
Demised  Premises;  provided,  however,  eviction of the Tenant by reason of the
foreclosure of any First Mortgage now or hereafter on the Demised Premises shall
not be  construed as a breach of this  covenant,  nor shall any action by reason
thereof be brought against the Landlord;  and provided further, that no eviction
of the Tenant for any reason whatsoever,  after the Landlord shall have conveyed
the fee of the Demised Premises shall be construed as a breach of this covenant,
and no action therefor shall be brought against the Landlord.

     28.  TERMINATION OF LEASE.  It is hereby  mutually agreed that either party
hereto may terminate  this Lease at the end of the Demised Term or at the end of
either  option  period by giving to the other party  written  notice  thereof at
least 180 days prior  thereto,  but in default of such notice,  this Lease shall
continue upon the same terms and  conditions in force  immediately  prior to the
expiration of the Demised Term hereof as are herein  contained  except for Basic
Rent which shall be adjusted to reflect the then current  market rates for space
comparable to the Demised Premises as determined by Landlord based upon other of
Landlord's rental properties for Melbourne, Florida, for a further period of one
year and so on from year to year  unless or until  termination  by either  party
hereto,  giving  the other one  hundred  eighty  (180) days  written  notice for
removal previous to expiration of the then current term; PROVIDED, however, that
should this Lease be continued for a further period under the terms herein-above
mentioned,  any  allowances  given  Tenant on the Basic Rent during the original
term shall not extend beyond such original terms. In the event that Tenant shall
give notice,  as  stipulated  in this Lease,  of intention to vacate the Demised
Premises at the end of the Demised  Term,  or any renewal or extension  thereof,
and shall  fail or refuse so to vacate the same on the date  designated  by such
notice, then it is expressly agreed that Landlord shall have the option either:

          (a) To  disregard  the notice so given as having no  effect,  in which
case all the terms and  conditions of this Lease shall continue  thereafter,  as
set forth above, with full force precisely as if such notice has not been given,
or

          (b)  Landlord  may, at any time  within  thirty days after the Demised
Term or any renewal or extension  thereof,  as  aforesaid,  give the said Tenant
fifteen (15) days' written  notice of his intention to terminate the said Lease;
whereupon the Tenant  expressly agrees to vacate said premises at the expiration
of the said fifteen (15) day period.

          All powers  granted to Landlord by this Lease may be exercised and all
obligations  imposed  upon Tenant by this Lease shall be  performed by Tenant as
well  during  any  extension  of the  Demised  Term of this  Lease as during the
Demised Term itself.

     29.  NOTICES.  All notices  required shall be in writing given by certified
mail, return receipt requested or by a recognized overnight delivery service:

mechanic's  lien to be filed  against  the  Demised  Premises by reason of work,
labor,  services or materials performed or furnished to Tenant or anyone holding
the  Demised  Premises,  or any part  hereof,  through or under  Tenant.  If any
mechanic's  lien or any notice of intention  to file a mechanic's  lien shall at
any time be filed against the Demised  Premises  Tenant shall at Tenant's  cost,
within  fourteen  (14) days  after  knowledge  or  notice  of the  filing of any
mechanic's lien cause the same to be removed or discharged of record by payment,
bond, order of a court of competent jurisdiction, or otherwise.

mechanic's lien within the prescribed  time, then in addition to any other right
or remedy of  Landlord,  Landlord  may,  at its  option,  procure the removal or
discharge  of the same by  payment  or bond or  otherwise.  Any  amount  paid by
Landlord  for such  purpose,  together  with all  legal and  other  expenses  of
Landlord  in  procuring  the  removal  or  discharge  of such  lien or notice of
intention  and together with interest  thereon at the highest  permissible  rate
shall be and become due and payable by Tenant to Landlord  as  additional  rent,
and in the event of Tenant's  failure to pay therefor  within  fifteen (15) days
after  demand,  the same shall be added to and be due and payable  with the next
month's rent.

          (c) NON-CONSENT OF LANDLORD TO FILING OF LIENS.  Nothing  contained in
this Lease  shall be  construed  as a consent on the part of Landlord to subject
Landlord's  estate in the Demised Premises to any lien or liability  arising out
of Tenant's use or occupancy of the premises.

     31. LEASE CONTAINS ALL AGREEMENTS. It is expressly understood and agreed by

Tenant  relative  to the  Demised  Premises,  and that  there  are no  promises,
agreements,  conditions or understandings,  either oral or written, between them
other  than are herein set forth.  It is  further  understood  and agreed  that,

wherever  stated herein,  shall be deemed to refer to the "Landlord" or "Tenant"
whether  such  Landlord  or Tenant be  singular  or plural and  irrespective  of
gender. No rights, however, shall inure to the benefit of any assignee of Tenant
unless the  assignment to such assignee has been approved by Landlord in writing
as aforesaid.

     33. SECURITY DEPOSIT. INTENTIONALLY OMITTED.

     34.  HEADINGS  NOT PART OF LEASE.  Any headings  preceding  the text of the

acreage of the Center (20.85 acres) by the acreage of the Land  (including  area

in all valid applications.

     39. LANDLORD'S LIABILITY.  Anything to the contrary herein notwithstanding,
Landlord's  liability for any damages or assessments  hereunder shall be limited
solely to  Landlord's  interest in the Demised  Premises or land and building of
which the Demised Premises is part, as the case may be. It is further covenanted
and agreed by the parties  hereto  that in no case shall the  Landlord be liable
for any consequential damages.

release of toxic or hazardous substances or materials, including those which are

limited to, those substances  listed in the Environmental  Statutes,  as defined
below,  polychlorinated  biphenyls ("PCB's"),  asbestos and materials containing
PCB's and asbestos (hereinafter  collectively "Hazardous Material"),  in, around
or from the Demised  Premises.  Tenant shall not store, use or allow the storage
or use of Hazardous  Materials  in or around the Demised  Premises in any manner
not  sanctioned by law or the highest  standards  prevailing in the industry for
handling  and storage of such  Hazardous  Materials.  In the event that any such
Hazardous  Materials are required to be used by Tenant in the ordinary course of
its business,  Tenant shall send at least five (5) days' advance  written notice
to Landlord of the uses of such substances, including any identification of such
substances or materials. Landlord may deny or restrict Tenant's use or manner of
use of such  Hazardous  Materials  in or around the Demised  Premises;  however,
Landlord's failure to deny or restrict Tenant's use of Hazardous Materials or to
advise  Tenant of an  objection  to Tenant's use or manner of use of same in the
Demised Premises does not indicate  Landlord's approval for such use and, in any
event,  Tenant  shall  remain  strictly  responsible  and liable for any and all
consequences,  direct  or  indirect,  resulting  from the use of such  Hazardous
Materials in or around the Demised Premises.

          (b) Tenant  shall  conduct all of its  operations  at the  Premises in

Reauthorization  Act of 1986,  Pub. L. No. 99-499,  100 Stat.  1613 (October 17,
1986) ("CERCLA"); the Resources Conservation and Recovery Act, 42 U.S.C. Section
6901  et.  seq.  ("RCRA"),  Florida  Air and  Water  Pollution  Control  Act and
regulations   enacted   thereunder),   ordinances,   regulations,   orders   and
requirements of common law, regarding, but not limited to, (i) discharges to the
air,  soil,  surface or  groundwater;  and (ii)  handling,  utilizing,  storage,
treatment or disposal of any hazardous substances or toxic substances as defined
therein ("Environmental Statutes"). Tenant shall obtain all permits, licenses or
approvals  and  shall  make all  notifications  and  registrations  required  by

any  correspondence  notice of  violation,  summons,  order,  complaint or other
documents  received  by  Tenant  pertaining  to  compliance  with  Environmental
Statutes.

permanent  tanks for the  storage  of any  liquid  or gas above or below  ground
except as in  compliance  with the other  provisions  of this  section and after
obtaining written permission to do so from Landlord.

          (d) If,  because of the manner in which Tenant  operates its business,
the Landlord,  Landlord's mortgage lender or a governmental agency shall require
testing by an environmental  testing entity of its choice,  to ascertain whether
there has been a release of Hazardous Materials by Tenant, its agents, servants,
employees  or  business  invitees,  in  or  around  the  Demised  Premises,  the
reasonable  costs of such testing  shall be  reimbursed by Tenant to Landlord as
Additional  Rent.  Tenant  shall  execute  affidavits  or  representations,   at
Landlord's request,  stating that, to the best of Tenant's knowledge and belief,
since the time that Tenant took possession of the Demised  Premises,  there have
been no and there  presently are no Hazardous  Materials  present in the Demised
Premises.

          (e) Tenant  hereby  agrees to indemnify  Landlord and to hold Landlord
harmless of, from and against any and all expense, loss, cost, fines, penalties,
loss of value or liability  suffered by Landlord by reason of Tenant's breach of
any of the provisions of this section.

          (f) The  provisions of this section shall survive the  termination  of
Tenant's tenancy or of this Lease.

     42. OPTION TO RENEW.

          Tenant  shall  have the right to extend the term of this Lease for two
(2)  additional  terms  of five  (5)  years  each  ("Extend  Terms  #1 and  #2),

either  Extended  Term  shall  commence,  Tenant  shall  not be in breach of the
performance  of any of the terms,  covenants or conditions of this Lease,  which
breach has not been remedied before an event of default has occurred;

          (c) Such  Extended  Term shall be upon the same terms,  covenants  and
conditions  as in this  Lease,  except that (i) there will be no right to extend
this Lease beyond  Extended  Terms #1 and #2, and (ii) the annual Basic Rent for
the Extended  Terms shall be calculated  (with  increases) in the same manner as
set forth in Paragraph 3(b) of the Lease.

          (d) Upon the giving of such notice in writing as aforementioned,  this
Lease shall be deemed extended for the Extended Term,  subject to the provisions
and conditions of this paragraph, without execution of any further instruments.

          (e) This Renewal Option may be assigned to a subtenant.

          IN WITNESS  WHEREOF,  the parties  hereto have executed these presents
the day and year first above written, intending to be legally bound hereby.

                             II. DETAILED PROVISIONS

1.   PREMISES.

     (a)  DESCRIPTION.  Landlord hereby leases to Tenant and Tenants leases from
Landlord, for the term and upon the terms, conditions,  covenants and agreements
hereinafter  provided,  the premises more particularly  described in Exhibit "A"
annexed  hereto  (the  "Premises")  located  in the  building  (the  "Building")
referenced above. The Premises contains 15,296 square feet of Rentable Area, 90%
or 13,766  square feet of which is Usable Area,  which Usable Area is defined by
the Washington Board of Realtors.

     (b)  LANDLORD'S  WORK.  Tenant  may be  entitled  to  certain  improvements
specified on Exhibit "B" attached hereto and  incorporated  herein by reference.
The work which  Landlord  agrees to perform  under the terms and  conditions  of
Exhibit  "B"  hereinafter  shall be  referred  to as  "Landlord's  Work."  It is
understood  and agreed  that  Landlord  is under no  obligation  to perform  any
alterations,  installations (including floor coverings),  decorations (including
painting  and  wall   coverings),   replacements,   additions  or  improvements,
structural  or otherwise,  in or to the Premises  except as set forth in Exhibit
"B".

2.  TERM

     (a) The "Term",  "Lease  Commencement Date" and "Lease Expiration Date" are
specified on page one of this Lease.

     (b) FAILURE TO DELIVER POSSESSION OF PREMISES. Landlord shall put forth its
best efforts to complete the Premises on or before the Lease  Commencement Date.
If Landlord's Work is not  substantially  completed (as defined in paragraph (e)
below) in accordance with Exhibit "B" on or before the Lease  Commencement Date,
or if Landlord shall be unable to give  possession of the Premises on such Lease
Commencement  Date  for  any  other  reason,  this  Lease  shall  not be void or
voidable,  and Landlord,  its agents or  employees,  shall not be subject to any
claim or liability whatsoever for the failure timely to complete such work or to
give possession on such date. If Landlord has not completed the  improvements as
shown on Exhibit "B", the Tenant shall have the right to use its own  contractor
and deduct the cost of construction from the rent.

     (c) DELAYS IN SUBSTANTIAL  COMPLETION CAUSED BY TENANT. If such substantial
completion  of Landlord's  Work in accordance  with Exhibit "B" shall be delayed
because of (i) Tenant's  failure to furnish its  requirements  and/or to approve
drawings, plans, specifications or cost estimates, including those pertaining to
additional or non-standard work and materials, by the dates specified by Exhibit
"B",  (ii)  Tenant's  request for changes in drawings,  plans or  specifications
after the date specified by Exhibit "B",  (iii) Tenant's  request for materials,
finishes or installations other than Landlord's Building Standard, as defined by
Exhibit "B", or (iv) the  performance  of any work by Tenant,  Tenant's  agents,
employees  or  contractors,   Landlord's  Work  shall  be  deemed  substantially
completed for the purpose of determining the Lease Commencement Date on the date
which Landlord reasonably determines, in its sole judgment, that such work would
have been substantially completed had such delay or delays not occurred.

     (d)  SUBSTANTIAL  COMPLETION  DEFINED.  The  Premises  shall  not be deemed
substantially  completed until all the work  undertaken by Landlord  pursuant to
Exhibit  "B" is  substantially  completed,  subject  to a punch  list  of  items
prepared by Tenant and Landlord on the Lease Commencement Date which items shall
not  materially  interfere  with Tenant's use of the  Premises.  Nothing in this
clause shall  effect  Tenant's  termination  right as described in Article 34 or
Tenant's occupancy of the Premises.

     (e) LEASE YEAR DEFINED. As used herein, "Lease Year" shall mean that period
of 365 days (366 in leap years) commencing on the Lease  Commencement  Date, and
each  successive  period  of 365 days (or 366  days in leap  years)  thereafter;
provided,  however, that if the Lease Commencement Date is a date other than the
first  day of a month,  then  the  first  Lease  Year  shall  mean  that  period
commencing on the Lease  Commencement Date and continuing for the balance of the
month in which said date occurs and for a period of 365 or 366 days  thereafter,
and the last  Lease Year shall  terminate  on the date this Lease  expires or is
terminated.

3.  RENT.

     (a) BASE ANNUAL  RENT.  The Base Annual  Rent as  specified  in the Summary
Provisions  of this  Lease  shall be  payable,  in  advance,  in  equal  monthly
installments,  specified as the Monthly Payment in the Summary Provisions hereof
by U.S. mail, courier or otherwise delivered to Landlord at the address provided
in Article 30 hereof or to such other party or to such other address as Landlord
may designate from time to time by written  adjustment as hereinafter  provided.
The first  Monthly  Payment  coming  due shall be made upon the  signing of this
Lease by Tenant, and the second and subsequent Monthly Payments shall be made on
the first day of each and every calendar month as provided  herein.  If the term
of this Lease begins on a date other than on the first day of a month, rent from
such date until the first of the  following  month shall be prorated at the rate
of one thirtieth  (1/30th) of the fixed Monthly Payment for each day, payable in
advance.

     (b)  INCREASE  IN COST  OF  LIVING.  Commencing  on the  first  day of each
calendar year following the calendar year in which this Lease commences,  Tenant
shall pay monthly  one-twelfth of an increase in the Base Annual Rent based upon
thirty  percent  (30%) of any  increase in the index now known as UNITED  STATES
BUREAU OF LABOR  STATISTICS,  CONSUMER  PRICE  INDEX FOR URBAN WAGE  EARNERS AND
CLERICAL WORKERS,  WASHINGTON, D.C. SMSA (1982-84=100).  All Items (the "Index")
over the Base Index (as defined herein). Notwithstanding the preceding sentence,
in no event shall the  adjustment  of Base Annual Rent for any calendar  year be
less than two and one-half  percent  (2.5%) of the Base Annual Rent as increased
from year to year hereby (the "Minimum Base Annual Rent  Adjustment").  In order
to apply such adjustments in a timely and convenient manner, Landlord and Tenant
agree  that  the  Base  Index  shall  be  the  Index  for  the  month  which  is
approximately  three months  prior to the month in which the Lease  Commencement
Date  occurs  and that  adjustments  of Base  Annual  Rent  shall be based  upon
comparison of the Index for the month of September  last  preceding the calendar
year for which an adjustment  is to be made (the "Current  Index") with the Base
Index.  For the purposes of this  paragraph,  Base Annual Rent which is adjusted
pursuant to this paragraph  shall be referred to as "Adjusted Base Annual Rent."
Adjusted Rent Annual Rent shall be computed as follows:  (i) the increase in the
Index shall be  determined  by dividing (A) the  difference of the Current Index
minus the Base Index,  by (B) the Base Index;  (ii) the  increase in Base Annual
Rent due to the increase in the Index shall be  determined  by  multiplying  the
original  Base Annual Rent  payable  hereunder  by thirty  percent  (30%) of the
increase in the Index;  (iii) the Adjusted Base Annual Rent shall be the greater
of (A) the original Base Annual Rent payable  hereunder plus the increase in the
Base Annual Rent due to the  increase  in the Index or (B) the  previous  year's
Adjusted  Base Annual Rent payable  hereunder  plus the Minimum Base Annual Rent
Adjustment.  Landlord promptly shall determine the Adjusted Base Annual Rent for
each  calendar  year,  as  hereinabove  provided,  and shall  submit to Tenant a
statement  setting  forth the amount of such  Adjusted  Base Annual Rent and the
calculation  by  which  it was  determined.  If the  base  year of the  Index is
changed,  the  Index  used to  determine  Adjusted  Base  Annual  Rent  shall be
converted in accordance  with the conversion  factor  published by the Bureau of
Labor  Statistics  of the United  States  Department  of Labor.  If the Index is
discontinued,  then any  successor  consumer  price  index of the United  States
Bureau of Labor  Statistics,  or successor  agency thereto,  for the Washington,
D.C.  Metropolitan  Area,  shall be used. If the Index is  discontinued  with no
comparable  successor  Index,  the parties shall use their best efforts to agree
upon a  substitute  formula,  but if the parties are unable so to agree,  then a
substitute formula shall be determined by arbitration as provided herein.

     (c) SERVICE CHARGE. Notwithstanding any of the other rights of Landlord set
forth in this  Lease,  if during the term of this  Lease,  Monthly  Payments  or
Additional  Rent remains unpaid on the tenth day after the date when the same is
required to be paid,  Landlord at its option,  may make a service charge for the
purpose of defraying the expenses  incidental to handling  delinquent  payments.
Such charge shall be in an initial amount of five percent (5%) of the delinquent
payment. In addition, Monthly Payments or Additional Rent which is not paid when
due shall bear  interest,  computed  from the date such item  becomes due to the
date of payment,  at a rate which shall be the lesser of (i) two percent  higher
than the "prime rate"  charged by Crestar Bank on the date such item becomes due
and fluctuating  thereafter as the "prime rate" charged by said Crestar Bank may
change from time to time or (ii) the maximum  rate of interest  then  allowed by
law.  Late charges  referenced  above shall be  applicable  only after  Landlord
provides  Tenant  notice of  Tenant's  second  event of failure to make a timely
payment of Base Annual Rent, Monthly Payments, or Additional Rent.

4.  ADDITIONAL RENT; OPERATING EXPENSE AND REAL ESTATE TAX INCREASES.

     (a) ANNUAL OPERATING EXPENSE INCREASE. Throughout the Term, Tenant shall be
obligated to pay as  Additional  Rent,  Tenant's pro rata share of the amount by
which  Operating  Expenses  (as  defined in Article  4(b)  hereof)  exceeds  the
Operating  Expense  Amount  specified  in the Summary  Provisions  hereof.  Such
payments shall be made as follows:

          (i) ESTIMATED  MONTHLY  PAYMENTS.  Within the first one hundred twenty
(120) days after the end of each calendar year (or portion  thereof)  during the
Term of Lease, Landlord shall furnish Tenant with Landlord's reasonable estimate
of the  Operating  Expenses  for the  then  current  calendar  year  (Landlord's
Operating Expense Estimate). Until the first day of the calendar month following
the  month in which  Tenant is given  Landlord's  Operating  Expense  Statement,
Tenant shall continue to pay to Landlord on the first day of each calendar month
the monthly sum, if any,  payable by Tenant  under this Article  4(a)(i) for the
month of December of the preceding calendar year.  Landlord shall give notice to
Tenant  stating  whether the Tenant's  monthly  payments  made  pursuant to this
Article 4(a)(i) during the then current  calendar year were greater or less than
the revised monthly payment stated in Landlord's Operating Expense Estimate, and
(i) if there  shall be a  deficiency,  Tenant  shall pay the  amount  thereof to
Landlord  within  thirty (30) days after the giving of Landlord's  estimate,  or
(ii) if there  shall  have been an  overpayment,  Landlord  shall pay the amount
thereof  to Tenant  within  thirty  (30) days  after  the  giving of  Landlord's
estimate,  and (iii) on the first day of the first calendar month  following the
month in which Tenant is given Landlord's estimate, and on the first day of each
calendar  month  thereafter  during the Term  throughout  the  remainder of such
calendar  year,  Tenant shall pay to Landlord an amount equal to  one-twelfth of
Tenant's  pro rata  share of the  amount by which  Operating  Expenses  for such
calendar year are estimated to exceed the Operating Expense Amount.

          (ii) ANNUAL  SETTLEMENT.  Beginning  with the first full calendar year
following the Commencement  Date, within the first one hundred twenty (120) days
after the end of each calendar year or portion  thereof,  Landlord shall furnish
to Tenant a detailed  statement setting forth the actual Operating  Expenses for
the previous  calendar year and Tenant's pro rata share of the increase over the
Operating Expense Amount (hereinafter "Actual Operating Statement").  Landlord's
failure  to  provide  the  Actual  Operating  Statement  within  the time  frame
referenced above shall not relieve Tenant of its obligations  hereunder.  Within
thirty (30) days after the delivery of the Actual  Operating  Statement,  a lump
sum  payment  will be made by  Tenant  equal  to the  amount,  if any,  by which
Tenant's pro rata share of the actual  increase in Operating  Expenses  over the
Operating  Expense  Amount  exceeds that amount,  if any,  which Tenant has paid
toward the estimated increase in Operating Expenses for the prior calendar year.
If  Tenant's  pro rata share of such items is less than the amount  Tenant  paid
toward the estimated  increase in Operating  Expenses,  Landlord shall reimburse
Tenant  in cash for the  difference  within  thrity  (30)  days afer the date of
Landlord's  delivery of its Actual Operating  Statement to Tenant. The effect of
this  adjustment  is that Tenant will pay during each  calendar  year during the
Term  Tenant's  pro rata  share of actual  Operating  Expenses  in excess of the
Operating Expenses Amount.

          (iii) PARTIAL YEARS. If the  Commencement  Date occurs on a date other
than the first day of a  calendar  year of the Term or  expires  on a date other
than  the last day of a  calendar  year,  then  the  actual  Operating  Expenses
incurred during such partial calendar years shall be computed and an appropriate
proration  shall be made in the actual  Operating  Expenses and in the Operating
Expense  Amount so that Tenant pays only that portion of Tenant's pro rata share
of excess Operating  Expenses  incurred during the portion of such calendar year
that includes the beginning of the end of the Term.

     (b) OPERATING  EXPENSES DEFINED.  The term "Operating  Expenses" shall mean
all costs and expenses (and taxes thereon,  if any) paid or incurred by Landlord
with respect to the ownership,  operation, cleaning, repair, safety, management,
security,  and  maintenance  of the  Building  (and  the land  upon  which it is
situated),  including,  but not  limited  to: (a) real  estate  taxes;  (b) gas,

limited to, chillers,  boilers,  controls,  elevators,  windows, security, trash
removal,  and any other Building  service or system;  (g) charges of independent

safety,  security,  and maintenance of the Building;  (h) maintenance and repair
expenses and  supplies;  (i) the cost or rental of all  Building and  management
office cleaning supplies,  materials, tools, and equipment; (j) management fees;
(k) legal, accounting, and other professional fees and disbursements incurred in
connection  with the  operation and  management  of the  Building;  (l) costs of
uniforms,  work clothes,  and dry cleaning;  (m)  depreciation of hand tools and
other  movable  equipment  used  for the  management  of the  Building;  and (n)
business taxes and licenses.  The term "Operating Expenses" shall include, also,
(a) expenditures for capital  improvements  and capital  equipment  purchased or
installed  for the purpose of  decreasing  Operating  Expenses,  but only to the
extent that relevant  decreases are applied in any given year. Such expenditures
for capital  improvements and capital equipment shall be amortized in subsequent
Lease Years on a straight-line  amortized basis over an appropriate  period, not
to exceed ten years,  together with interest on the unamortized cost fluctuating
at the "prime rate" charged by Crestar Bank (as changed from time to time).  The
term  "Operating  Expenses" shall exclude;  (a)  executives'  salaries above the
grade of building manager; (b) expenditures for capital improvements and capital
equipment other than those specified above; (c) principal and interest  payments
on any mortgages,  deeds of trust or other financing  encumbrances;  (d) leasing
commissions payable by Landlord;  (e) deductions for depreciation;  (f) costs of
repairs  or  replacements  incurred  by  reason  of fire or  other  casualty  or
condemnation  to the extent  Landlord is compensated for same; and (g) the costs
of preparing, improving or altering space for any new or renewal tenant.

     (c) REAL ESTATE TAX  COMPONENT  OF  OPERATING  EXPENSES.  As a component of
"Operating  Expenses",  the term "real estate taxes" shall include all taxes and
assessments,  general and  special,  ordinary  and  extraordinary,  foreseen and
unforeseen,  including assessments for public improvements or betterments, which
Landlord reasonably  determines are assessed,  levied or imposed with respect to
the Building,  the land on which it stands or Landlord's  personal property used
in  connection  therewith;  any tax in the nature of a real  estate  tax;  an AD
VALOREM tax on rent;  any tax on income if imposed in lieu of, in addition to or
as a component of real estate taxes and assessments; and all reasonable expenses
incurred by Landlord in  obtaining or  attempting  to obtain a reduction of such
taxes, rates or assessments,  including, reasonable attorney fees. Any REDUCTION
shall be applied in its correct  proportion  to the Tenant's  operating  expense
statements in the year the adjustment is made.

     (d)  TENANT'S  PRO RATA  SHARE.  Tenant's  pro rata share of any  Operating
Expense  increase  shall  be the  percentage  amount  specified  in the  Summary
Provisions of this Lease,  which  represents  the proportion of rentable area of
the Premises divided by the total rentable area of the Building.

     (e) ANNUAL STATEMENTS. Each Actual Operating Statement provided by Landlord
hereunder  shall be conclusive  and binding upon Tenant  unless Tenant  notifies
Landlord  within 30 days after any such  statement is given that it disputes the
correctness of such statement and states with  particularity the items disputed.
Unless  otherwise  mutually  agreed,  any such dispute  shall be  determined  by
arbitration  in  Washington,  D.C.,  pursuant to the rules then obtaining of the
American Arbitration Association, and judgment on the award rendered thereby may
be entered in any court of competent jurisdiction.  Pending determination of any
such dispute,  Tenant shall pay Additional  Rent in accordance with the disputed
statement (and the most recent Estimated Annual Operating Expense Increase given
by Landlord to Tenant), but such payments shall not prejudice Tenant's challenge
of the  disputed  statement.  Upon  notice  given by Tenant to Landlord at least
fifteen (15) days in advance, Tenant shall have reasonable access, during normal
business  hours,  to  appropriate  books and  records of  Landlord  relating  to
Operating Expenses for the purpose of verifying,  at Tenant's sole expense,  any
Actual Operating Expense Statement.

     (f) OTHER  ADDITIONAL  RENT. All other sums of money or charges required to
be paid by Tenant to Landlord under this Lease shall be deemed  Additional  Rent
and shall be due and payable  fifteen days after  Landlord  gives Tenant  notice
thereof.  Tenant's  failure  to pay any sum or  charged  required  to be paid by
Tenant to  Landlord  under  this  Lease  when due shall  carry  with it the same
consequences  as  Tenant's  failure  to  pay  Monthly  Payments  and  any  other
Additional Rent payable hereunder when due.

5. USE.

     (a) PERMITTED USE. Except as provided in paragraph (b) below,  Tenant shall
use and occupy the  Premises  solely  for office  space  during the Term of this
Lease and for no other purpose without the prior written consent of Landlord.

     (b)  COMPLIANCE  WITH  LAW.   Tenant  (and  its  permitted   assignees  and
subtentants)  shall not use or permit the use of the  Building,  the Premises or
any part  thereof for any  disorderly,  unlawful or hazardous  purpose,  or in a
manner  which will  obstruct or  interfere  with the rights of other  tenants or
their  invitees or in any way injure or annoy them, or in any manner which would
tend to lower the  first-class  character of the building.  Tenant,  at its sole
cost and  expense,  shall  comply  promptly  with all present  and future  laws,
ordinances,  rules,  regulations,  orders or  requirements  of all  governments,
departments,  commissions,  boards  and  public  officers  which may  impose any
violation,  order or duty  (including  the duty to perform  alterations to or to
install  equipment in its Premises)  upon Landlord or Tenant with respect to the
Premises  or the  Building  arising out of Tenant's  use or  occupancy  thereof.
Tenant shall pay as Additional  Rent all costs,  expenses,  fines,  penalties or
damages  which may be imposed  upon  Landlord by reason of  Tenant's  failure to
comply with the provision of this  paragraph.  Landlord  assumes no liability or
responsibility  whatsoever  with  respect  to the  conduct or  operation  of the
business  conducted  in the  Premises.  Tenant shall not do or permit any act or
thing to be done to the Premises or to the  Building  which will  invalidate  or
cause an increase in the premium of any public  liability,  fire or other policy
of  insurance  at any time  carried by or for the  benefit of  Landlord or which
might  subject  Landlord to liability  for injury to any person or damage to any
property. If any increase in the premium of any public liability,  fire or other
policy of  insurance  is stated by any  insurance  company or by any  applicable
governmental  ratings  bureau to be due to any  activity  done or  permitted  by
Tenant in or to the Premises or the Building, such statement shall be conclusive
evidence that the increase in such premium is due to such  activity,  the Tenant
shall pay to Landlord the amount of such increase as Additional Rent.

     (c) SUITABILITY OF PREMISES.  Tenant hereby accepts the Premises, which may
be improved  by  Landlord  as  described  in Section  1(b),  in their  condition
existing  as of the  day  Tenant  takes  possession  hereunder,  subject  to all
applicable zoning,  local and State laws,  ordinances and regulations  governing
and regulating the use of the Premises and accepts the Lease subject thereto and
to all matters  disclosed  thereby and by any exhibits  attached hereto.  Tenant
acknowledges   that  neither   Landlord  nor  Landlord's   agent  had  made  any
representations  or  warranties  as to the  suitability  of the Premises for the
conduct of Tenant's business.

6. SECURITY DEPOSIT.

     The  Security  Deposit  shall  be the same  Deposit  which  Tenant  made to
Landlord with its lease dated April 10, 1990 and which Landlord hereby agrees to
transfer as Security  for the Lease (see Exhibit  "F").  Such  security  deposit
shall be  considered  as security for  obligations,  covenants,  conditions  and
agreements  under the Lease and shall be held by Landlord in an interest bearing
account.  Upon the  expiration  of the term hereof (or any renewal or  extension
thereof in accordance with this Lease),  Landlord shall (provided that Tenant is
not in default under the terms hereof) return and pay back such security deposit
along with  interest  accrued to Tenant  less such  portion  thereof as Landlord
shall have  appropriated  to make good any default by Tenant with respect to any
of Tenant's aforesaid obligations,  covenants, conditions and agreements. In the
event of any default by Tenant hereunder during the term of this Lease, Landlord
shall have the right, but shall not be obligated, to apply all or any portion of
the  security  deposit to cure such  default,  in which  event  Tenant  shall be
obligated, promptly to deposit with Landlord the amount necessary to restore the
security deposit to its original amount. In the event of the sale or transfer of
Landlord's  interest in the  Building,  Landlord  shall have the  obligation  to
return  the  security  deposit to the Tenant or  transfer  said  deposit to such
purchaser  or  transferee,  in which  event  Tenant  shall  look only to the new
Landlord for the return of the security deposit, and Landlord shall thereupon be
released from all  liability to Tenant for the return of such security  deposit.
Landlord shall not be required to keep Tenant's  security  deposit in an account
separate from Landlord's own accounts.

7. SERVICES AND UTILITIES.

     Landlord shall furnish to Tenant reasonably adequate electricity,  exterior
window  cleaning  service  (as  required)  in  Landlord's  sole  and  reasonable
judgment,  and, provided the Premises are kept in good order by Tenant, cleaning
and char service in conformance with  specifications  attached hereto as Exhibit
"C" after 5:00 p.m.  on Monday  through  Friday  (exclusive  of New Year's  Day,
President's Day, Memorial Day,  Independence  Day, Labor Day,  Thanksgiving Day,
and Christmas Day).  Landlord shall not be responsible  for cleaning,  repair or
other  maintenance  (except  vacuuming)  of carpets,  rugs or drapes  within the
Premises,  whether provided by Landlord or not, and such items shall be the sole
responsibility  of  Tenant.  Landlord  shall  replace  light  bulbs or tubes for
Building  standard  lighting  fixtures  only.  Landlord  shall furnish rest room
facilities, necessary lavatory supplies and running water for the general use of
the  tenants of the  Building.  Landlord  shall  furnish  automatically-operated
elevator service and at least one elevator will be subject to call at all times.
Landlord shall furnish heat and air conditioning from 8:00 a.m. to 6:00 p.m., on
Monday through Friday  (exclusive of New Year's Day,  President's Day,  Memorial
Day,  Independence Day, Labor Day, Thanksgiving Day, and Christmas Day) and from
9:00 a.m. to 1:00 p.m. on Saturday,  during those  seasons of the year when such
services are normally and usually  furnished in comparable  office  buildings in
the Northern Virginia suburbs of the Washington, DC metropolitan area and within
the temperature ranges and in such amounts normally or usually furnished in such
comparable office buildings.  If Tenant requires heat or air conditioning beyond
the hours  specified by this  paragraph,  Landlord shall furnish such additional
heat or air  conditioning  upon  notice of such  requirement  given to  Landlord
(verbal,  written or by means of automated  system, as required by landlord from
time to time) no later than noon of the last  business day  preceding the day on
which Tenant requires such additional heat or air conditioning. Tenant shall pay
to  Landlord  as  Additional  Rent a  charge  for  such  additional  heat or air
conditioning in accordance  with  Landlord's  then current  schedule of charges,
which may be made and  changed  from  time to time  without  notice  to  Tenant.
Landlord  shall provide a security  system for the Building;  PROVIDED  HOWEVER,
that no  representation  or  warranty is made by  Landlord  with  respect to the
adequacy, completeness or integrity of the security system so provided. Landlord
reserves  the right to change or modify  the  security  system or guard  service
(including  right  to  substitute  one for the  other)  at any  time in its sole
judgment. Landlord shall not be liable in any respect for failure to furnish, or
for  suspension or delays in furnishing,  any of the services  described by this
paragraph as a result of breakdown,  maintenance,  repairs,  strike, riot, civil
commotion,  scarcity of labor or  materials,  acts of God or any cause or reason
whatever beyond the control of Landlord; nor shall any such failure,  suspension
or delay be deemed an  eviction,  actual or  constructive,  entitling  Tenant to
terminate this Lease or to any reduction or adjustment of rent hereunder. If any
public  utility or  governmental  authority  having  jurisdiction  shall require
Landlord  or Tenant to  restrict  consumption  of any  utility  or to reduce any
service for the Premises or the Building,  Landlord and Tenant shall comply with
such requirement without any reduction or adjustment of rent hereunder.

8. RULES AND REGULATIONS.

     Tenant and Tenant's agents, employees,  contractors,  invitees and licenses
shall  observe  faithfully  and comply  strictly with all  reasonable  rules and
regulations  promulgated  by  Landlord at any time and from time to time for the
general  well-being,  safety,  care  and  cleanliness  of the  Premises  and the
Building.  Landlord  shall put forth in best  efforts to enforce such rules upon
all tenants.  Nothing in this Lease shall be  construed to impose upon  Landlord
any duty or  obligation  to enforce any rule or  regulation  or any  covenant or
agreement in any lease as against any other  tenant,  and Landlord  shall not be
liable to Tenant for violation of the same by any other tenant of the Building.

9. ALTERATIONS.

     (a) APPROVAL BY LANDLORD.  Tenant shall not make, or cause to be made,  any
alterations,  installations (including floor coverings),  decorations (including
painting  and  wall   coverings),   replacements,   additions  or  improvements,
structural or otherwise, (hereinafter collectively referred to as "alterations")
in or to the  Premises  or the  Building  without the prior  written  consent of
Landlord  which  consent  shall  not  be  unreasonably  withheld.  Landlord  may
condition  such  consent  upon  Tenant's  written  agreement  to pay the cost of
additional  utility  consumption,  if any,  and to restore the  Premises and the
Building to the  condition  in which they were found  immediately  prior to such
alteration  and upon the  requirement  that  Tenant  post a security  deposit to
secure  performance of such agreement.  Landlord also may condition such consent
upon its  prior  approval  of  plans  and  specifications  and  contractors  and
subcontractors with respect to such alterations,  and such alterations shall not
be  commenced   until  such  plans  and   specifications   and  contractors  and
subcontractors  have been  submitted to and approved by Landlord.  Such approval
shall not be unreasonably withheld or delayed.  Upon such approval,  alterations
shall be  commenced  promptly,  performed  in a good and  workmanlike  manner in
accordance  with the approved plan and  specifications,  and diligently  carried
forward to completion.  Any alterations  performed by Tenant shall be subject to
Landlord's  inspection  and approval after  completion to determine  whether the
same comply with matters approved by Landlord.  It is understood and agreed that
any  alterations  performed  in or to the Premises or the  Building,  other than
Landlord's  Work,  shall be made on  behalf  of  Tenant,  and not on  behalf  of
Landlord,  and that  Tenant  shall be deemed the  "owner" and not the "agent" of
Landlord  with respect to such  alterations.  If any  alteration is performed by
Tenant  without the prior written  consent of Landlord,  Landlord may correct or
remove same and restore the Premises and the Building to the  condition in which
they were found  immediately  prior to such alteration at Tenant's sole cost and
expense,  and Tenant  shall pay to  Landlord  as  Additional  Rent all costs and
expenses incurred by Landlord for such correction or removal.

     (b) PERMITS AND INSURANCE  COVERING TENANT  ALTERATIONS.  Tenant  covenants
that any  alterations  which it shall perform  shall be in  conformity  with all
applicable  laws,  ordinances,  rules,  regulations,  orders or  requirements of
governmental  authorities  having  jurisdiction  and  all  applicable  insurance
requirements. Before commencing any alterations, Tenant shall obtain at its sole
cost  and  expense  all  permits,   approvals  and   certificates   required  by
governmental  authorities  having  jurisdiction  and promptly  shall  deliver to
Landlord  duplicates  of all such permits,  approvals,  and  certificates.  Upon
completion of any alteration  performed by Tenant,  Tenant shall obtain,  at its
sole cost and expense, certificates of final approval thereof and promptly shall
deliver to Landlord duplicates of all such certificates.  In connection with any
Tenant  alterations,  Tenant shall carry,  and shall cause its  contractors  and
subcontractors to carry, workmen's compensation, general liability, and personal
and property  damage  insurance  in such amounts and with such  companies as are
reasonably satisfactory to Landlord.

     (c) MECHANIC'S  LIENS.  Tenant shall obtain and deliver to Landlord written
and  unconditional  waivers  of  mechanics'  and  materialmen's  liens  upon the
Building and the Land for all labor and services  which have been  performed and
materials  which have been  furnished  in the  Premises  or in the  Building  in
connection   with  any   tenant   alterations,   signed   by  all   contractors,
subcontractors, materialmen and laborers. If, notwithstanding the foregoing, any
mechanic's or  materialmen's  lien is filed against the Building or the Land for
labor,  services or materials  claimed to have been  furnished for Tenant,  such
lien shall be discharged by Tenant within ten days after the filing thereof,  at
Tenant's  sole cost and expense,  by the payment  thereof or by posting the bond
required  by law.  If  Tenant  shall  fail so to  discharge  or  bond  any  such
mechanic's or  materialmen's  lien within the time agreed upon,  Landlord may do
so, at Tenant's sole cost and expense,  without  inquiring  into the validity of
such lien,  and Tenant  shall pay to Landlord as  Additional  Rent all costs and
expenses of same (including  reasonable  attorneys  fees).  Tenant's  failure to
discharge or bond any such mechanics' or  materialman's  liens shall be deemed a
default under this Lease,  and the discharge of any such lien by Landlord  shall
not be deemed to waive or release such default.

     (d) REMOVAL BY TENANT.  Unless otherwise agreed by Landlord and Tenant, all
alterations  in or to the  Premises  or the  Building,  whether  with or without
Landlord's  consent and whether  Landlord's  Work or Tenant  alterations,  shall
become the property of Landlord at the  expiration or  termination of this Lease
and shall be in good  working  order.  Unless  otherwise  agreed by Landlord and
Tenant,  Tenant shall not remove any such alterations.  Trade fixtures installed
by Tenant may be removed prior to the expiration or termination of this Lease if
all rents due herein are paid in full,  Tenant is not then  otherwise in default
hereunder, and Tenant restores the Premises to good condition.

     (e) INDEMNIFICATION.  Tenant hereby indemnifies and agrees to save harmless
Landlord and any mortgagee of the Building  against and from any cost,  expense,
lien, damage, claim or liability (including reasonable attorneys fees) which may
arise directly or indirectly by reason of the  performance of any alterations by
Tenant in or to the Premises or the Building.

10. CARE OF PREMISES.

     (a) REPAIRS AND  MAINTENANCE  BY  LANDLORD.  During the term of this Lease,
including  any  extensions  thereof,  and  during  any  period of  holding  over

defects in the  foundation,  floor slab and walls of the  Premises,  upon notice
from Tenant of the necessity for same, and shall keep and maintain in good order
and  repair the  exterior  windows,  exterior  walls,  and  common  areas of the
Building, the fixtures and equipment serving the Building generally,  and sewer,
utility (other than telephone),  and water lines within the Building serving the
Premises.

     (b) REPAIRS AND MAINTENANCE BY TENANT.  Other than those elements for which
Landlord is specifically  responsible,  during the Term of this Lease, including
any extensions thereof, and during any period of holding over hereunder, Tenant,
at its sole cost and  expense,  shall keep and maintain the Premises in a clean,
safe and sanitary condition.

     (c) DAMAGE CAUSED BY TENANT.  Tenant shall be responsible for all damage or
injury to the Premises,  to the alterations and equipment therein or appurtenant
thereto, to alterations and equipment performed or installed by Tenant elsewhere
in the Building,  and to any part of the Building or to the Building's  fixtures
and equipment,  caused by or resulting from carelessness,  omission,  neglect or
improper conduct of Tenant, Tenant's agents, employees, contractors, invitees or
licensees.  Tenant shall repair  property so damaged or injured to a quality and
class equal to the original work or construction. In the event Tenant shall fail
within  thirty (30) days after  notice by Landlord to commence  such repairs and
diligently  pursue same to completion,  Landlord shall commence such repairs and
Tenant  shall pay the  Landlord  as  Additional  Rent an amount  equal to all of
Landlord's  costs and expenses of repairing damage or injury for which Tenant is
responsible hereunder.  In addition, if such repairs are performed by Landlord's
employees  or by more  than one  contractor,  Tenant  shall pay to  Landlord  as
Additional  Rent an amount  equal to 25 percent of  Landlord's  direct costs and
expenses of such repairs,  representing  Landlord' s administrative  costs and a
reasonable mark-up for providing such service. Tenant also shall pay to Landlord
as Additional  Rent the amount of rent payable by other tenants which is lost by
Landlord as a result of damage or injury to property caused by or resulting from
carelessness,  omission, neglect or improper conduct of Tenant, Tenant's agents,
employees,   contractors,  invitees  or  licensees.  The  above  provisions  are
additional  remedies  granted to Landlord and are not in limitation of any other
rights and  remedies  which  Landlord  may have under this Lease or at law or in
equity.  Notwithstanding  the foregoing,  Tenant shall not be liable to Landlord
for any cost,  expense or loss of rent under this  paragraph  to the extent that
Landlord is insured  against such hazards and damages under an insurance  policy
containing a waiver of subrogation clause and to the extent that the proceeds of
such insurance  actually  compensate  Landlord for such cost, expense or loss of
rent.

     (d) NOTICE OF DEFECTIVE CONDITION. Tenant shall give Landlord prompt notice
of any apparent defects to the foundations, floor slab and walls of the Premises
and of any apparent defective  condition in the plumbing,  heating or electrical
systems located in, servicing or passing through the Premises.

11. ACCESS TO PREMISES.

     (a)  TENANT'S  ACCESS.  Tenant  shall  have  access  to the  Premises  on a
full-time 24-hour basis, subject to such reasonable restrictions as Landlord may
impose for security or maintenance reasons.

     (b)  LANDLORD'S  ACCESS.  Landlord  and its agents  with  prior  reasonable
written or verbal  notice to Tenant shall have the right to enter (but shall not
be obligated to enter) the Premises at all reasonable  times to inspect same, to
make such repairs or  alterations  as Landlord may deem necessary and reasonably
desirable or in compliance with laws, ordinances, rules, regulations,  orders or
requirements  of any  governmental  authority  having  jurisdiction.  During the
progress of any repairs or  alterations  performed by Landlord in the  Premises,
Landlord  may take all  necessary  materials  and  equipment  into the  Premises
without the same  constituting an eviction,  actual or  constructive,  entitling
Tenant to terminate  this Lease,  to any reduction or adjustment of rent for the
period during which such work is in progress or to any damages by reason of loss
or interruption  of business or otherwise.  Tenant shall permit Landlord to use,
maintain,  and replace  pipes and  conduits in and through the  Premises  and to
erect new pipes and conduits  therewith.  Landlord shall have the right to enter
the Premises during normal  business  hours,  throughout the term of this Lease,
for the purpose of showing the same to  prospective  purchasers or mortgagees of
the  Building,  and during the last six months of the term,  for the  purpose of
showing  the same to  prospective  tenants  of the  Premises.  No lock  shall be
changed and no  additional  lock shall be placed  upon any door of the  Premises
without Landlord's prior written consent,  which consent may be conditioned upon
Tenant's  furnishing  to Landlord a duplicate  key to such changed or additional
lock.  If Tenant is not  present to open and permit an entry into the  Premises,
Landlord or its agents may enter the same,  whenever such entry may be permitted
by this Lease, by master key, keys provided by Tenant or forcibly, if necessary,
provided reasonable care is exercised to safeguard Tenant's property. All damage
done to the  Premises  by  Landlord's  permitted  forcible  entry as a result of
Tenant's  failure  to  provide a  duplicate  key to any lock  shall be  repaired
promptly by Landlord,  and Tenant shall pay to Landlord as  Additional  Rent the
cost of  expense  of such  repair.  If,  after  giving  or  receiving  notice of
termination or  non-extension  of this Lease,  as above  provided,  Tenant shall
remove all or  substantially  all of its property  from the  Premises.  Landlord
thereupon may enter the Premises and perform  alterations in and to same without
reduction or adjustment of rent and without liability to Tenant.

     (c) EMERGENCY  REPAIRS.  If, in order to prevent  damage to the Premises or
the Building, or to prevent harm to person or property in the Building, it shall
become  necessary  promptly to make any repair  within the  Premises  and Tenant
shall not be immediately available to permit entry, then Landlord may enter (but
shall not be  obligated  to enter) the  Premises  at any time for the purpose of
making such repair.

12. TENANT'S EQUIPMENT.

     (a)  ELECTRICAL  EQUIPMENT.  Tenant  shall not  install  or  operate in the
Premises or in the Building  any  electrically  operated  equipment or machinery
which  operates at a capacity of greater  than 120 volts/12  amps without  first
obtaining the written  consent of Landlord.  Landlord may condition such consent
upon (i) Tenant's agreement to pay the cost for additional wiring and facilities
occasioned  by the  operation of such  equipment or machinery  and (ii) Tenant's
securing  any  necessary  permits  from  governmental  authorities  and  utility
companies.  Tenant  shall not  install  or  operate  in the  Premises  or in the
Building any equipment or machinery which may affect the general use of any such
system  without first  obtaining the written  consent of Landlord.  Landlord may
condition  such  consent  upon  Tenant's  agreement  to pay the cost of  change,
replacements  or additions in Building  systems  necessary  for the operation of
such equipment or machinery.  Tenant shall not operate in the Premises or in the
Building any  equipment or machinery  which causes noises or vibration to such a
degree  as to be  objectionable  to  Landlord  or to  any  other  tenant  of the
Building.

     (b) EXCESS  ELECTRICAL  USAGE.  Tenant shall pay to Landlord as  Additional
Rent the cost of any  electricity  consumed by Tenant in excess of an average of
five watts per square foot of  approximate  rentable area of the Premises.  Upon
determining  Tenant's regular requirement of electricity in excess of an average
of five watts per square foot of  approximate  rentable area of the Premises per
month  Landlord  shall have the right to install a separate  meter  serving  the
Premises to measure Tenant's additional electrical consumption. Such meter shall
be installed,  maintained and read by Landlord.  Tenant shall pay to Landlord as
Additional Rent the cost and expense of installation,  maintenance,  and reading
of such meter.

     (c) HEAVY EQUIPMENT.  Tenant shall not place or install in the Premises any
equipment,  machinery  or  fixture  which  shall  place a load upon any floor in

to carry.  Landlord  shall have the right to  prescribe  the  weight,  method of
installation,  and position of any heavy  equipment,  machinery or fixture which
Tenant  desires  to  place  or  install  in the  Premises.  Notwithstanding  any
prescription by Landlord, Tenant shall be liable to Landlord for any damage done
to the  Premises or the  Building by the  placement,  installation,  presence or
removal  of such heavy  equipment,  machinery  or  fixture  to the  extent  that
Landlord is not insured against such damage under an insurance policy containing
a waiver of  subrogation  clause and to the  extent  that the  proceeds  of such
insurance do not actually compensate Landlord for such damage.

13. SIGNS.

     No sign,  advertisement or notice shall be inscribed,  painted,  affixed or
otherwise  displayed  on any part of the inside or the  outside of the  Building
without the prior written  consent of the  Landlord,  which consent shall not be
unreasonably  withheld or delayed. If any such sign,  advertisement or notice is
nevertheless displayed by Tenant without Landlord's consent, Landlord may remove
such  sign,  advertisement  or  notice,  and  Tenant  shall pay to  Landlord  as
Additional Rent the cost and expense of such removal.

14. INSURANCE.

     (a)  INSURANCE  TO BE  PROCURED  BY  TENANT.  Tenant,  at its sole cost and
expense,  shall  obtain and maintain in effect all times during the term of this
Lease,  including  any renewals  thereof,  and during any period of holding over
hereunder, policies of insurance providing for the following coverages:

          (i) A policy covering Tenant's trade fixtures and equipment  installed
and located  within the Premises;  any  alterations  made by Tenant in or to the
Premises or the Building, whether or not removable by Tenant upon the expiration
or termination of this Lease, and all of the furnishings,  merchandise and other
contents  within the  Premises,  for the full  replacement  value of such items.
Coverage  shall at least insure against any and all perils  included  within the
classification "Fire and Extended Coverage" under insurance industry practice in
the state  wherein the  Building is located,  together  with  insurance  against
vandalism,  malicious  mischief and sprinkler leakage or other sprinkler damage.
Any proceeds of such insurance  insuring  alterations which are not removable by
Tenant upon the  expiration or  termination  of this Lease shall be used only to
repair or replace the items so insured or to compensate Landlord for their loss.

          (ii) A comprehensive  policy of general liability insurance protecting
against liability for bodily injury,  personal injury,  death or property damage
occurring  in or about any part of the  Premises or the Building or arising from
any of the acts set forth in Section 15 to the extend  such acts are  reasonably
insurable  under a  general  liability  policy,  with  such  policy to be in the
minimum amounts providing such coverages as are usual and customary.

     There  shall  be  a  single   occurrence   limit  of  One  Million  Dollars
($1,000,000.00) for all of the above coverages.

     (b) GENERAL PROVISIONS GOVERNING POLICIES. All insurance policies herein to
be  obtained  by  tenant  (i)  shall be  issued  by good and  solvent  insurance
companies licenses to do business in the state in which the Building is located;
(ii) shall be written as primary policy coverage and not contributing with or in
excess of any coverage which  Landlord or its  mortgagees  may carry;  and (iii)
shall insure and name  Landlord and any  mortgagee of the Building as additional
insureds as their  respective  interests  may appear.  Each and every  insurance
policy required to be carried  hereunder by or on behalf of Tenant shall provide

shall certify) that,  unless  Landlord shall first have been given 30 days prior
written notice hereof; (i) such insurance policy shall not be canceled and shall
continue in full force and effect;  and (ii) no material  changes may be made in
such insurance policy. Upon request by Landlord, Tenant shall give to Landlord a
duplicate  original or certified copy of each policy, or renewal of a policy, of
insurance  required  herein to be obtained by Tenant,  together with evidence of
payment of all applicable premiums.  Neither the issuance of any policy required
hereunder  nor the minimum  limits  specified  herein  with  respect to Tenant's
insurance  coverage  shall be deemed to limit or  restrict  in any way  Tenant's
liability  arising under or out of this Lease.  The term  "insurance  policy" as
used  herein  shall be  deemed to  include  any  extension  or  renewal  of such
insurance  policy.  In the event that Tenant shall fail  promptly to furnish any
insurance coverage  hereunder required to be obtained by Tenant,  Landlord shall
have the right to obtain (but shall not obligated to obtain) the same and to pay
the premium for same for a period not to exceed one year in each  instance,  and
Tenant shall pay to Landlord the amount of such premium paid by Landlord.

     (c) WAIVER OF  SUBROGATION.  Landlord and Tenant hereby  release each other
from any claim for damage or loss to the Premises, the Building or any person or
property  caused  by or  resulting  from any  risks  insured  against  under any
insurance policies carried by Landlord or Tenant and in force at the time of any
such  damage or loss,  to the  extent  that  such  damage  or loss  actually  in
compensated by insurance proceeds, regardless of the cause of the damage or loss
(including  the  negligence  of  Landlord  or Tenant).  All  insurance  policies
required to be obtained and  maintained by Tenant under this Lease shall contain
an express wavier of any right of subrogation by the insurance  company  against
Landlord.  Likewise, all insurance policies obtained by Landlord with respect to
the Premises and the Building  shall  contain an express  waiver of any right of
subrogation by the insurance company against Tenant.

of the sole negligence of Landlord.

     (b) LANDLORD'S  INDEMNITY.  Landlord hereby  indemnifies and agrees to save

non-performance of this Lease or any provision therefor by Landlord. Landlord at
its  sole  cost  and  expense,  shall  defend  any and all  actions,  suits  and
proceedings which may be brought against Tenant,  its agents or employees,  with
respect to the foregoing or in which they may be impleaded,  and Landlord  shall
satisfy and  discharge  any and all  judgments,  orders and decrees which may be
recovered  against  Tenants,  its agents or employees,  in  connection  with the
foregoing.  Landlord  shall pay to  Tenant  the  amount  of any cost,  expenses,
damage,  claim or  liability  incurred  by Tenant  against  which  Landlord  has
indemnified Tenant hereunder.  Notwithstanding  any of the foregoing  sentences,
Landlord  shall not be liable for any claims or  liabilities  arising out of the
sole negligence of Tenant.

16. LIABILITY OF LANDLORD.

     Landlord and its agents,  employees and contractors  shall not be liable to
Tenant,  its  agents,  employees,  contractors,  invitees or  licensees  for any
damage, claim or liability arising from: (a) the necessity for making repairs to
the Premises or the Building and any  resultant  interruption  of the use of the
Premises or any part of the Building;  (b) accident or damage in connection with
the use or operation by any person of elevators or heating, cooling,  electrical
or plumbing  equipment in the Building;  (c) fire,  robbery,  theft,  mysterious
disappearance or any other casualty;  (d) leakage of water, steam, rain, snow or
any other  substance into or from any part of the Premises or the Building;  (e)
any failure of any security  system;  (f) any personal injury resulting from the
use, occupancy or condition of the Premises; or (g) termination of this Lease by
reason of the  destruction  of the  Premises;  provided,  however,  that nothing
herein  shall be construed to relieve  Landlord and its agents,  employees,  and
contractors from liability for gross negligence or willful  misconduct.  No such
event or events shall be deemed an eviction, actual or constructive,  and Tenant
shall not be entitled to terminate  this Lease or to any reduction or adjustment
of rent as a result of any such event or events. Any goods, property or personal
effects of Tenant,  its agents,  employees,  contractors,  invitees,  licensees,
customers,  family members or guests stored or place in or about the Premises or
the Building  shall be at the sole risk of the owner of such goods,  property or
personal effects, and Landlord shall not be responsible for same.

17. DAMAGE BY FIRE OR OTHER CASUALTY.

     (a) DUTY TO RESTORE.  If,  during the term of this Lease,  or any  renewals
thereof,  or any period of holding over hereunder,  the Premises or the Building
is damaged or rendered totally or partially  inaccessible or unusable by fire or
other  casualty,  this Lease shall continue in full force and effect,  except as
hereinafter  provided,  and Landlord diligently and as soon as practicable after
such damage  occurs  (taking  into account the time  necessary  to  effectuate a
satisfactory  settlement with any insurer involved with Landlord exercising good
faith  efforts to attain a  settlement  as soon as  reasonably  possible)  shall
restore  and repair the  Premises  and the  Building to  substantially  the same
condition  in  which  they  were  found  prior to such  fire or other  casualty,
exclusive  of  alterations  required  to  be  restored  or  repaired  by  Tenant
hereunder.  If such fire or other  casualty was not caused by the  carelessness,
omission,  neglect or improper conduct of Tenant or Tenant's agents,  employees,
contractors,  invitees or licensees,  Landlord shall bear the costs and expenses
of such  restoration  and repair.  If however  such fire or other  casualty  was
caused by the carelessness,  omission,  neglect or improper conduct of Tenant or
Tenant's agents, employees,  contractors' invitees or licensees, then Tenant, to
the extent such actions  contributed to such fire or other casualty,  shall bear
the cost and  expense  of such  restoration  and  repair.  If this  Lease is not
terminated,  as  hereinafter  provided,  Tenant  shall  restore and  repair,  at
Tenant's  sole cost and  expense,  any  alterations  made by Tenant in or to the
Premises  or the  Building  which  are  damaged  or  destroyed  by fire or other
casualty  during the term of this  Lease or during  any  period of holding  over
hereunder to substantially  the same condition in which they were found prior to
such fire or other  casualty or Tenant shall request  alterations  thereto which
are  subject to  Landlord's  reasonable  consent.  Tenant  shall be bound by the
provisions  of  Article 9 of this  Lease in  making  any  restoration  or repair
required or permitted by this paragraph.

     (b) RIGHT TO TERMINATE.  Landlord shall have the right, at its sole option,
to terminate  this Lease by giving notice of such  termination  to Tenant within
ninety (90) days from the date of such  damage if (a)  settlement  of  insurance
claims and Landlord's  restoration and repair of the Premises damaged by fire or
other casualty  cannot be fully  completed  within 90 days from the date of such
damage of (b) the Building  shall be so damaged by fire or other  casualty  that
substantial  reconstruction  of the  Building  is  required  (whether or not the
Premises have been damaged or rendered untenantable or inaccessible). This Lease
shall terminate immediately upon the giving of such notice.

     Tenant shall have the right, at its sole option, to terminate this Lease by
giving notice of such termination to Landlord within 90 days of the date of such
damage if (a) Landlord's  restoration and repair of the Premises damaged by fire
or other  casualty  cannot  be  completed  within  90 days from the date of such
damage, if an and only if such damage id not arise out of any willful, careless,
negligent, or improper act of Tenant or Tenant's agents, employees, contractors,
invitees  or   licenses.   For  the   purposes   of  this  Lease,   "substantial
reconstruction"  shall mean reconstruction which is reasonably estimated to cost
in excess of 25 percent of the replacement value of the Building.

     (c) RENT  ABATEMENT.  If this Lease is not  terminated in the event of such
fire or the  casualty,  and  provided  that such fire or other  casualty was not
caused by or did not result  from  carelessness,  omission,  neglect or improper
conduct  of Tenant or  Tenant's  agents,  employees,  contractors,  invitees  or
licensees,  until the  restoration  and  repair of the  Premises  (exclusive  of
alterations for which Tenant is responsible  hereunder or which Tenant elects to
perform)  is  completed,  Tenant  shall pay any rent  whether  characterized  as
Monthly  Payments or  Additional  Rent only for that part of the  Premises  that
Tenant is able to use while restoration and repair is made, based upon the ratio
that the amount of area usable by Tenant  compared to the usable  square feet of
the Premises  determined  pursuant to Section 1(a) above.  So long as this Lease
shall  remain  in  effect,  Tenant  shall be  entitled  to a  reduction  of rent
hereunder  only to the extent that such fire or other casualty was not caused by
or was not resulting from carelessness, omission, neglect or improper conduct of
Tenant or Tenant's agents, employees, contractors, invitees or licensees.

18. CONDEMNATION

     If all or a substantial  part of the Premises is taken or condemned for all
public or  quasi-public  use or purpose by any competent  authority,  this Lease
shall  terminate  as the  date of such  taking  or  condemnation,  and the  rent
required otherwise to be paid by Tenant hereunder shall be abated as of the date
of such taking.  If less than a substantial  part of the Premises is so taken or
condemned,  the rent required to be paid by Tenant  hereunder shall be equitably
adjusted  based upon the ratio that the amount of rentable  square feet shall be
equitable  adjusted based upon the ratio that the amount of rentable square feet
remaining  available  for  Tenant's  use and  occupancy  after  such  taking  or
condemnation  bears  to the  rentable  square  feet of the  Premises  determined
pursuant to Section 1(a) above,  and this Lease otherwise shall continue in full
force and effect.  In either event,  Tenant shall have no claim against Landlord
for the value of the unexpired  portion of the term of this Lease.  Tenant shall
have no claim or right to any  portion  of the  amount  that may be  awarded  as
damages or paid as a result of any such taking or  condemnation,  and all rights
of  Tenant  to  damages  therefor,  if any,  are  hereby  assigned  by Tenant to
Landlord.  Tenant, however, shall be entitled to claim, prove and receive in the
condemnation  proceedings  such awards as may be allowed for alterations made by
Tenant in or to the Premises of the Building  which are removable by Tenant upon
the expiration or  termination  of this Lease,  or for any other type of special
damages allowable by law to Tenant, but only if any and all such awards shall be
made by the  condemnation  court in addition to and stated  separately  from the
award  made by it for the  Building  and the land on which  it  stands,  or part
thereof,  so taken. For the purposes of this article,  a substantial part of the
Premises  shall be  deemed to have been  taken if more  than 50  percent  of the
approximate  rentable square feet of the Premises determined pursuant to Section
1(a) above is  unusable  by Tenant as a direct  result of such  taking.  For the
purposes  of  this  Section,  any  purchase  by a  competent  authority,  or its
designee,  of all or part of the  Premises,  in lieu of taking  or  condemnation
thereof under powers of eminent  domain,  shall be deemed to be an actual taking
or condemnation thereof.

19. SURRENDER OF PREMISES

     Upon the  expiration of  termination  of this Lease,  Tenant shall quit and
surrender the Premises broom clean and in good condition, ordinary wear and tear
and damage by fire or other casualty excepted.  Landlord shall have the right to
retain,  at no cost to Landlord,  any Tenant  alterations or improvements to the
Premises constituting Landlord's Work. Tenant shall remove from the Building all
personal  property  (other  than  any  property  constituting  Landlord's  Work)
belonging  to Tenant or Tenant's  agents,  employees,  contractors,  invitees or
licensees,  and if Tenant fails to remove any such  property  from the Building,
such property shall be deemed to have been abandoned,  and Landlord, at its sole
option,  may  retain  possession  thereof or may cause the same to be removed at
Tenant's sole cost and expense. Tenant agrees to reimburse Landlord for the cost
of such removal  together  with any and all damages  which  Landlord may sustain
thereby.  Tenant's obligation to perform the covenants contained in this Section
shall survive the expiration or termination of this Lease.

20. ASSIGNMENT, SUBLETTING

     (a) Tenant (and its permitted  assignees and subtenants)  shall not assign,
mortgage or encumber this Lease, or sublease the Premises, or permit the same or
any part  thereof to be used by others,  without  the prior  written  consent of
Landlord in each instance, nor shall any assignment or transfer of this Lease or
the right to occupancy hereunder be effectuated by operation of law or otherwise
without the prior  written  consent of  Landlord.  Any  attempted  or  purported
assignment,  mortgage  or  encumbering  of this  Lease or of  Tenant's  interest
hereunder and any  attempted or purported  subletting or grant of a right to use
or occupy all or any portion of the Premises  without the prior written  consent
of  Landlord  shall be null and void and shall not confer  any  rights  upon any
purported assignee, mortgagee,  transferee,  sublessee or occupant. Tenant shall
give notice to Landlord of any  proposed  sublease or  assignment  not less than
fifteen  (15) days prior to the  effective  date of such  proposed  sublease  or
assignment,  and such notice shall  include a copy of the  proposed  sublease or
assignment.  Landlord  shall approve or disapprove of such request no later than
ten (10) days after  receipt of such  request.  Landlord's  consent shall not be
unreasonably withheld or delayed.

     (b) Landlord  shall approve of a proposed  sublease in accordance  with the
terms of Paragraph  20(a) hereof if (i) such  sublease is expressly  subject and
subordinate to this Lease;  (ii) such sublease  provides that the subtenant must
abide by all of the terms and  conditions  of this  Lease;  (iii) such  sublease
provides that any expiration or  termination of this Lease shall  extinguish the
sublease as well;  (iv) the rent payable to Tenant  under such  sublease for any
subleased  space be no less than the pro rata rent  payable by Tenant  hereunder
for such space; (v) if the net rent (i.e.,  rental and other  consideration less
all fees,  costs and  related  expenses  incurred by tenant in  completing  said
sublease and delivering the sublease  premises to the new subtenant)  payable to
Tenant under such sublease  space  exceeds the rent payable by Tenant  hereunder
for such space,  the sublease  must provide that Tenant shall pay to Landlord as
Additional  Rent One-half of the amount of any such net excess (and/or other net
consideration in addition to rent) paid by Tenant on the first day of each month
following receipt by Tenant of any such payment; (vi) the proposed subtenant has
a credit rating satisfactory to Landlord, in Landlord's reasonable Judgment; and
(vii) the proposed  subtenant  is engaged in a business or activity  which would
not tend to lower the first-class character of the Building.

     (c) In the event that a proposed  sublease  is not  approved by Landlord in
accordance with the criteria set forth herein, then in that event Landlord shall
have the right to elect,  within ten (10)  additional  days  thereafter,  (a) to
terminate this Lease with respect to that portion of the Premises (including the
whole thereof) for which a sublease is proposed,  (b) to sublet from Tenant that
portion of the  Premises for which a sublease is proposed at the rent then being
paid by Tenant for such portion by a proportionate  reduction or rent payable by
Tenant as  hereinafter  set forth,  or (c) to consent or refuse  consent to such
proposed sublease.  If Landlord shall elect to terminate this Lease with respect
to any portion of the  Premises  for which  Tenant has proposed a sublease or to
sublet such potion of the Premises , Tenant shall  surrender to Landlord for the
term of the sublease  such portion of the Premises on the  commencement  date of
the proposed sublease,  and thereafter the Base Annual Rent, Additional Rent and
all other related financial  matters shall be appropriately  adjusted based upon
the ratio that the rentable area of the Premises remaining after such surrenders
bears to the rentable  area of the Premises  first  herein  recited.  This Lease
otherwise shall continue in full force and effect.

     (d) If this Lease is  assigned,  or if the  Premises or any part thereof is
sublet or occupied by any person,  firm or  corporation  other than Tenant,  and
Landlord,  if permitted,  fails to elect to terminate this Lease with respect to
the applicable portion of the Premises so transferred, Landlord may collect rent
from the assignee,  subtenant or occupant and apply the net amount  collected to
the account of rent  payable by Tenant  under this Lease and any excess shall be
promptly  paid to  Tenant,  but no such  assignment,  subletting,  occupancy  or
collection  shall  be  deemed a waiver  or  release  of  Tenant's  covenants  or
obligations under this Lease.

     (e) Notwithstanding any other section in this Article 20, Tenant shall have
the right to sublet space to XEN, Inc. without  Landlord's  approval and without
sharing any of its "profits" if there are any, with Landlord.

21. DEFAULT OF TENANT

     (a)  DEFAULT  DEFINED.  A default  under this Lease shall be defined as the
occurrence of any one or more of the following events (a "Default").

          (i) Tenant's  failure to pay any installment of the Monthly Payment or
Additional  Rent on or  before  the date on which  such  installment  is due and
payable  under  this  Lease,  although  no legal or formal  demand has been made
therefor;

          (ii)  Tenant's  violation  of, or failure to perform,  any other term,
condition, covenant or agreement under this Lease;

          (iii) The appointment of a receiver or custodian for any or all of the
property or assets of Tenant,  the institution of a foreclosure  action upon any
real or  personal  property of Tenant or the filing of an  involuntary  petition
against  Tenant as the subject  debtor under the  bankruptcy  provisions  of the
United States Code (the "Bankruptcy  Code") or under this insolvency laws of any
State,  District,  Commonwealth  or Territory of the United States  ("Insolvency
Laws") which either is not dismissed  within 30 days of filing or results in the
issuance of an order for relief against the debtor within 30 days of filing;

          (iv) The filing of a voluntary  petition  under the  provisions of the
Bankruptcy Code or Insolvency Law by Tenant; or

          (v) The  making or  consenting  to an  assignment  for the  benefit of
creditors or a common law composition of creditors by Tenant.

     (b) LANDLORD'S REMEDIES.  Should a Default occur under this Lease, Landlord
may pursue any or all of the following remedies:

          (i) TERMINATION OF LEASE.  Landlord may terminate this Lease by giving
notice of such termination to Tenant, (1) if Tenant is in default due to failure
to pay Monthly Payment(s) or Additional Rent when due, or (2) if Tenant fails to
cure any  nonmonetary  default  within ten days after such notice (which ten day
period shall be extended for such additional period of time as reasonably may be
necessary  to cure such  default if by its nature such  default  cannot be cured
within such ten day period,  so long as, however,  Tenant shall commence to cure
such default  within such ten day period and shall  proceed  diligently  to cure
same); PROVIDED, HOWEVER, that this subparagraph may not be invoked while a case
under the  Bankruptcy  Code is pending in which  Tenant is the  subject  debtor,
unless  Tenant or its  Trustee  in  Bankruptcy  is  unable  to  comply  with the
provisions of subparagraph 21 (b)(vi), 21 (b)(vii), and 21 (b)(viii) below. Upon
the giving of notice,  this Lease shall  terminate and Tenant shall be obligated
to quit and  surrender  the  Premises.  Any  other  notice  to quit or notice of
Landlord's  intention  to  re-enter  is hereby  expressly  waived by Tenant.  If
Landlord  elects to terminate this Lease,  all covenants and  agreements  herein
made by  Landlord  shall  cease  without  prejudice  to the right of Landlord to
recover from Tenant all rent accrued to the time of  termination  or recovery of
possession  of the  Premises  by  Landlord,  whichever  is later,  and any other
monetary damages or loss sustained by Landlord,  including,  but not limited to,
loss of rent, costs of advertising,  commissions, physical alterations, and rent
concessions of any kind.

          (ii) SUIT FOR POSSESSION.  Upon  termination of this Lease pursuant to
subparagraph  21(b)(i),  Landlord  may  proceed  to  recover  possession  of the
Premises under and by virtue of the provisions of the laws of the state in which
the Building is located,  or by such other  proceedings,  including re-entry and
possession, as are permitted by law.

          (iii)  RELETTING OF PREMISES.  Should this Lease be terminated  before
the  expiration of the term of this Lease,  including any renewals  thereof,  by
reason of Default of Tenant,  the Premises may be relet by Landlord or such rent
and upon  such  terms as are  reasonable  under the  circumstances.  If the full
amount of rent payable by Tenant under this Lease and costs, expenses or damages
sustained  by  Landlord  as a result of Default of  Tenant,  including,  without
limitation,   additional   administrative  costs,   reasonable  attorneys  fees,
brokerage  fees and  expenses of placing the  Premises in  first-class  rentable
condition,  shall not be realized by landlord  through  such  reletting,  Tenant
shall be liable for any deficiency in such amount. In preparing the Premises for
such reletting,  Landlord,  at its sole option,  may make such  alternations and
repairs in and to the Premises as Landlord considers advisable and necessary for
the purpose of reletting same, and the making of such alterations and/or repairs
shall not operate or be construed to release  Tenant from  liability  hereunder.
Landlord  shall not be liable to Tenant for failure to relet the Premises or, in
the event the  Premises  are  relet,  for  failure  to  collect  rent under such
reletting.  Tenant shall not be entitled to receive any excess o rent  collected
by Landlord  under such reletting over the full amount of rent payable by Tenant
under this Lease and costs,  expenses  or damages  sustained  by  Landlord  as a
result of Default of Tenant.

          (iv) ADDITIONAL  SECURITY.  If, for three months of any period of four
consecutive months,  Tenant shall fail to pay any monthly installment of rent on
or before  the tenth day of the month in which  such  payment  is due under this
Lease,  Landlord  may declare the total amount of monthly  installments  of rent
payable under this Lease for either the six months immediately  following or the
last six  months of the Lease Term to be due and  payable  within ten days after
Landlord  gives  notice  to  Tenant  of such  action.  For the  purpose  of this
subparagraph,  the term  "monthly  installment  of rent" shall mean the total of
monthly installments of Base Annual Rent and Additional Rent payable for a month
under  this  Lease.   Landlord  shall  hold  any  amount   received  under  this
subparagraph  in escrow,  to be applied to satisfaction of Tenant's rent account
for such six-month period (whether such period be for the six months immediately
following or the last six months of the Lease Term) as each  installment of rent
otherwise  shall become due and payable.  This  subparagraph  may not be invoked
while a case under the Bankruptcy Code is pending in which Tenant is the subject
debtor.

          (v) MONETARY DAMAGES. Any damage or loss of rent sustained by Landlord
as a result of Default of Tenant may be  recovered by  Landlord,  at  Landlord's
option, at the time of reletting all or a portion of the Premises or in separate
action,  or from time to time,  as said damage or loss shall have been made more
easily  ascertainable  by partial,  initial or  successive  relettings,  or in a
single  proceedings  deferred until the expiration of the term of this Lease, or
any renewals  thereof,  (in which event Tenant  hereby  agrees that the cause of
action  shall be deemed to accrue upon the  expiration  or  termination  of this
Lease), or in a single  proceedings prior to either the time of reletting or the
expiration of the term of this Lease, or any renewals  thereof,  in any of which
events  Tenant  agrees to pay to Landlord,  as agreed  liquidated  damages,  the
present value,  at ten percent per annum,  of rent which would have been payable
from  the end of the  period  for  which  Tenant  has  paid  rent  to the  Lease
Expiration Date. Upon payment of such agreed liquidated damages, Tenant shall be
under no further  liability  with  respect to such  period.  In the event Tenant
shall  become  the  subject  debtor in a case  under the  Bankruptcy  Code,  the
provisions  of this  subparagraph  may be  limited by the  limitation  of damage
provisions of the Bankruptcy Code.

          (vi)  ASSUMPTION OR  ASSIGNMENT BY TRUSTEE.  In the event Tenant shall
become the subject debtor in a case under the Bankruptcy Code,  Landlord's right
to terminate this Lease pursuant to  subparagraph  21 (b)(i) shall be subject to
the rights of the Trustee in  Bankruptcy  to assume or assign  this  Lease.  The
Trustee  shall not have the right to assume or  assign  this  Lease  unless  the
trustee (a)  promptly  cures all Defaults of Tenant;  (b)  promptly  compensates
Landlord for monetary  damages  incurred as a result of such  Defaults;  and (c)
provides adequate assurance of future performance.

          (vii) ADEQUATE  ASSURANCE OF FUTURE  PERFORMANCE.  Landlord and Tenant
hereby agree in advance that adequate assurance of future  performance,  as used
in subparagraph 21 (b)(vi) above,  shall mean that all of the following  minimum
criteria  must be met:  (a) the Trustee or Tenant must pay to  Landlord,  at the
time the next monthly  installment of rent is due under this Lease,  in addition
to such  monthly  installment  of rent,  an amount  equal to the total amount of
monthly  installments  of rent  payable  under this  Lease for the three  months
immediately  following,  and  Landlord  shall hold said  amount in escrow  until
either the Trustee or Tenant  defaults in its  payments of rent under this Lease
(whereupon  Landlord  shall have the right to apply  funds held in escrow to any
deficiency  in  Tenant's  rent  account) or until the  expiration  of this Lease
(whereupon  such funds shall be  returned  to the  Trustee or  Tenant);  (b) the
Tenant or Trustee  must agree to pay to  Landlord,  at any time the  Landlord is
authorized  to and does apply the funds as  escrowed,  the amount  necessary  to
restore such escrow account to the original level required by this subparagraph;
(c) the  Trustee  must agree that  Tenant's  business  shall be  conducted  in a
first-class   manner  and  that  no   liquidating   sale   auctions,   or  other
non-first-class  business operation shall be conducted in the Premises;  (d) the
trustee  or Tenant  must agree  that the use of the  Premises  as stated in this
Lease will remain unchanged;  and (e) the Trustee must agree that the assumption
or  assignment  of this  Lease  will not  violate  or affect the rights of other
tenants in the Building. For the purpose of this subparagraph, the term "monthly
installment of rent" shall mean the total of monthly installments of Base Annual
Rent and Additional Rent for a month under this Lease.

          (viii) FAILURE TO PROVIDE  ADEQUATE  ASSURANCE.  In the event Tenant's
Trustee is unable (a) to cure Tenant's Defaults,  (b) to compensate Landlord for
Landlord's  monetary  damages,  (c) to pay the rent due under this Lease without
Default  and (d) to meet the  criteria  and  obligations  imposed by 21 (b)(vii)
above,  then Tenant agrees in advance that its Trustee has not met its burden to
provide  adequate  assurance  of  future  performance,  and  this  Lease  may be
terminated by Landlord in accordance with subparagraph 21 (b)(i).

     (c) LANDLORD'S RIGHT TO PERFORM FOR ACCOUNT OF TENANT. If Tenant shall fail
to make any payment or to do any act  required by this Lease,  Landlord may (but
shall not be required to) make such payments or do such act for and on behalf of
Tenant.  Tenant agrees to pay to Landlord the amount of any such payment and the
cost of expense of any such act  (including  without  limitation  attorney fees)
paid or  carried  out by  Landlord  on  Tenant's  behalf and  interest  thereon,
computed from the date of Landlord's payment of such item to the date of payment
to  such  item  by  Tenant,  at a rate  which  shall  be the  lesser  of (i) two
percentage  points in excess of the "prime rate"  charged by Crestar Bank on the
date such item  becomes  due and  fluctuating  thereafter  as the  "prime  rate"
charged by said Bank may change  from time to time or (ii) the  maximum  rate of
interest then allowed by law.

     (d) WAIVER.  If Landlord  shall  institute a proceeding  against  Tenant in
enforcement  of the provisions of this Section and a compromise or settlement of
such proceeding shall be made, the election so to compromise or settle shall not
constitute a waiver of any  condition,  covenant or agreement  set forth by this
Lease or of any other  rights of Landlord  hereunder.  Waiver by Landlord of its
remedy for any breach of any condition,  covenant or agreement set forth by this
Lease shall not operate as a waiver of such condition,  covenant or agreement or
of Landlord's right to remedy for any subsequent breach thereof.  The receipt by
Landlord  of rent with  knowledge  of the breach of any  condition,  covenant or
agreement  of this  Lease  shall not be deemed a waiver  of such  breach  and no
provision  of this Lease shall be deemed to have been waived by Landlord  unless
such waiver is in writing  signed by  Landlord.  Payment by Tenant or receipt by
Landlord of a lesser  amount than the amount or rent then due and payable  shall
be deemed to be on account of the earlier installment of rent due at the time of
such payment.  Landlord's  acceptance of any payment in a lesser amount than the
amount  of rent  then  due  and  payable  shall  not be  deemed  an  accord  and
satisfaction,  and  Landlord  may  accept  such  payment  without  prejudice  to
Landlord's  right to recover  the  balance  due and to pursue  any other  remedy
provided in this Lease.  No act or thing done by landlord or  Landlord's  agents
during the term of this Lease shall be deemed an  acceptance  of a surrender  of
the Premises, and no agreement to accept such surrender shall be valid unless in
writing  signed by  Landlord.  No employee  or agent of Landlord  shall have any
power to accept the keys of the Premises  prior to the expiration or termination
of this Lease,  and the delivery of keys to any such employee or agent shall not
operate as a termination of the Lease or a surrender of the Premises.

     (e) EFFECT OF DEFAULT ON TENANT'S RIGHTS. For so long as a Tenant's Default
exists and  remains  uncured  by Tenant,  Tenant  hereby  forfeits  its right to
exercise any provision hereof or any amendment made hereto.

     (f) ADDITIONAL  REMEDIES.  The rights and remedies of Landlord specified by
this Lease shall be in addition to any other fright and remedy now and hereafter
provided  by law.  All such  rights and  remedies  shall be  cumulative  and not
exclusive of each other,  and Landlord may exercise  such rights and remedies at
such  times,  in such  order,  to such  extent  and as often as  Landlord  deems
advisable,  without  regard  to  whether  the  exercise  of one  right or remedy
precedes, concurs with or succeeds the exercise of another.

22. FORCE MAJEURE

     Except as expressly  provided  otherwise  in this Lease,  in the event that
Landlord  or  Tenant  is in  any  way  delayed  interrupted  or  prevented  from
performing any of its non-monetary  obligations under this Lease and such delay,

hereinafter  contained,  and for  other  good and  valuable  consideration,  the
receipt and adequacy of which is hereby acknowledged, Company and Employee agree
as follows:

1.   Employment.  Company  hereby  employs the Employee and the Employee  hereby
     accepts  employment  upon  the  terms  and  conditions  set  forth  in this
     Agreement.  Employee will serve as Exigent  President  and Chief  Operating
     Officer of Company,  at the  discretion  of the Company's  Chief  Executive

     Agreement  ("Term")  shall  begin on the  business  day this  Agreement  is
     executed  (the  "Commencement  Date"),  and end at  midnight  on the  third
     anniversary of the  commencement  date,  unless  extended.  The Term may be
     extended by mutual written  agreement of the Company and Employee  provided
     the  parties  shall  agree in  writing  at  least  three  months'  prior to
     expiration of the Term.

3.   Compensation.

     (a)  For all services  rendered by the Employee under this  Agreement,  the
          Company  shall pay and Employee  shall accept an annual  salary of ONE
          HUNDRED FORTY-FIVE THOUSAND and NO/100 DOLLARS ($145,000) per annum or
          lesser  amount,  on a pro rata basis,  for any period less than a full
          year.  This  compensation  shall  be  payable  to  Employee  in  equal
          installments in accordance with the Company's normal pay periods,  and
          shall be subject to all appropriate withholding taxes.

          The  annual  salary  payable  to  Employee  will be  subject to upward
          adjustment as determined by Company's  management  and approved by the
          Board of Directors in the event that Company generates annual revenues
          equal to or greater than that specified in an approved three-year plan
          (the "Plan").

     (b)  In addition to the compensation provided for in Section 3(a), Employee
          shall be granted  options  to  purchase  up to  100,000  shares of the
          common  stock,  $.01 par value per  share,  of  Company  (the  "Common
          Stock"),  at an  exercise  price of $2.25 per share of 110% of current
          market  value  whichever  is higher  and on the  terms and  conditions
          described in the  Incentive  Stock Option  Agreement,  which  Employee
          agrees to sign,  attached hereto as Exhibit A and incorporated  herein
          by this reference.

     (c)  Provided that Employee has not been  terminated for due cause (as that
          term is defined  below in Section 8), in addition to the  compensation
          provided for in Section (3)(a) above,  Company shall grant to Employee
          options to purchase an additional  72,500 shares of Common Stock at an
          exercise  price of $2.25 per  share or 110% of  current  market  value
          whichever is higher if Company  shall  receive on or prior to February
          1, 1998. (See annual Executive Incentive Plan), including

          of the options to purchase  such 72,500 shares of Common Stock even if
          none of the foregoing  conditions are achieved on or prior to February
          1, 1998. If and to the extent any such options are awarded pursuant to
          this Section 3(c),  they shall be awarded on the terms and  conditions
          described in the form of the Incentive Stock Option Agreement,  except
          that the amount of Common Stock  subject  thereto shall be adjusted to
          reflect the amount to which Employee is then entitled.

               equal  installments  in  accordance  with  Company's  normal  pay
               periods  for  Employee  (i.e.   weekly,   bi-weekly  or  monthly)
               beginning one pay period after the effective date of termination;

               Employee  as of the  effective  date of  termination,  payable in
               equal  installments  in  accordance  with  Company's  normal  pay
               periods for Employee beginning one pay period after the effective
               date of termination;

          (iii)If Employee is so  terminated  without due cause within the third
               twelve months of the Term ("Third Year"),  an amount equal to six
               (6) months' salary,  based on the then current salary of Employee
               as of  the  effective  date  of  termination,  payable  in  equal
               installments in accordance with Company's  normal pay periods for
               Employee  beginning  one pay period after the  effective  date of
               termination; and

          (iv) If  Employee is still  employed by Company  after the Third Year,
               and (in the absence of any superseding  arrangement with Company,
               whether pursuant to renewal of this Agreement or otherwise) is so
               terminated  without  due  cause,  an  amount  equal to three  (3)
               months'  salary,  based on the then current salary of Employee as
               of  the  effective   date  of   termination,   payable  in  equal
               installments in accordance with Company's  normal pay periods for
               Employee  beginning  one pay period after the  effective  date of
               termination.

     (d)  In the  event  of  termination  by the  Company  pursuant  to  Section
          8(a)(iv) (i.e. without due cause),  Employee shall also be entitled to
          receive,  at his option and upon his written  request,  group  medical
          insurance as described in Section  3(d)(ii) during the period Employee
          is entitled  to receive  severance  pay under  Section  8(d) plus,  if
          applicable,    any    additional    extension   of   the    applicable
          "Non-Competition   Period"  (as  defined  in  the  Non-Disclosure  and
          Non-Competition   Agreement,   pursuant   to  Section   3(g)  of  such
          agreement).

     (e)  In the event of termination  upon  Employee's  disability  pursuant to
          Section 8(a)(ii),  the Company agrees to continue  Employee's  regular
          salary  payments  from the date of  termination  through  the date the
          insurance company commences long term disability insurance payments or
          denies coverage.  In the event long term disability coverage is denied
          due to admitted or proven fraud on behalf of the Employee, the Company
          will have no severance payment obligations to Employee. If coverage is
          denied for any other reason, Employee's termination will be treated as
          termination without due cause under Section 8(a)(iv) and Employee will
          be entitled to  severance  pay under  Section  8(c)  provided any such
          regular salary payments made by Company to Employee under this Section
          8(e) will be credited against Company's severance payment obligations.

     (f)  Notwithstanding  anything to the contrary set forth in this Agreement,
          in the event that Employee  dies during the Term of this  Agreement or
          any extension thereof, this Agreement shall terminate upon the date of
          such death,  provided that in the event of Employee's death during the
          Term of this  Agreement  or any  extension  thereof the Company  shall
          continue  to pay  Employee's  salary for a period of ninety  (90) days
          following  the date of death to the executor or  administrator  of the
          Employee's estate,  except in no event shall the Company be liable for
          the  payment of any such  death  benefit  which  exceeds  the  maximum
          severance payment obligations pursuant to Section 8(e) above.

     interpretive effect whatsoever.

13.  No Conflict. Employee represents and warrants that performance of the terms
     of this  Agreement,  and the terms of any agreement  attached  hereto as an
     Exhibit, to the best of his actual knowledge, will not breach any agreement
     entered into by Employee,  and Employee  agrees that he will not enter into
     any agreement in conflict with this Agreement and the  agreements  attached

     disclose to Company any  proprietary or confidential  information  owned by
     any  third  party  which he is  prohibited  from  disclosing  by  reason of

14.  Injunctive  Relief.  Employee  acknowledges and agrees that a breach of his
     obligations under this Agreement,  and any agreement  attached hereto as an
     Exhibit  or  any  other  exhibit  or  attachment  hereto,  will  result  in
     irreparable and continuing harm to the Company,  for which there will be no
     adequate  remedy at law,  and  agrees  that in the  event of any  breach or
     prospective  breach of this  Agreement,  the Company,  its  successors  and

     necessity  or posting  bond or other  security  therefor  and  without  the
     necessity of proving irreparable harm, and to such other and further relief
     as may be  proper.  Employee  hereby  submits  to the  jurisdiction  of the
     preceding courts for the purposes of any actions or proceedings  instituted
     by the  Company to obtain  such  injunctive  relief,  and  agrees  that the
     process may be served on the Employee by registered mail,  addressed to the
     last  address  of the  Employee  known  to the  Company,  or in any  manner
     authorized by law.

15.  Severability.  If  for  any  reason  whatsoever,  any  one or  more  of the
     provisions  of this  Agreement  shall be held or deemed to be  inoperative,
     unenforceable or invalid as applied to any particular case or in all cases,
     such  circumstances  shall not have the effect of rendering  such provision
     invalid in any other case or of rendering  any of the other  provisions  of
     this Agreement inoperative, unenforceable or invalid.

16.  Assignability.  By reason of the special and unique  nature of the services
     hereunder,  it is agreed that neither party hereto may assign any interest,
     rights  or duties  which it or he may have in this  Agreement  without  the
     prior  written  consent of the other  party,  except  that upon any merger,
     liquidation,  or  sale of all or  substantially  all of the  assets  of the
     Company to another  corporation,  this Agreement shall inure to the benefit
     of and be  binding  upon the  Employee  and the  purchasing,  surviving  or
     resulting  company or corporation in the same manner and to the same extent
     as though such company or corporation were the Company.

17.  Waivers.  The  failure  or delay  of the  Company  at any  time to  require
     performance  by the employee of any  provision of this  Agreement,  even if
     know,  shall not affect the right of the Company to require  performance of
     that provision or to exercise any right, power or remedy hereunder, and any
     waiver by the  Company of any  breach of any  provision  of this  Agreement
     should not be construed as a waiver of any continuing or succeeding  breach
     of such  provision,  a waiver of the provision  itself,  or a waiver of any
     right,  power or remedy  under  this  Agreement.  No notice to or demand on
     Employee in any case  shall,  of itself,  entitle  Employee to any other or
     further notice or demand in similar or other circumstances.

18.  Indemnification. Company agrees to exercise its power to indemnify Employee
     in  the  situations  provided  in  the  Company's  current  Certificate  of
     Incorporation  in its form filed with the  Secretary of State for the State
     of Delaware as of the date of this Agreement.  This  indemnification  shall
     apply even if such Certificate is later amended or deleted.

19.  Covenants  of the  Essence.  The  covenants  of Employee  set forth in this
     Agreement and the other  Exhibits are the essence of this  Agreement;  they
     shall be construed as independent of any other provision in this Agreement;
     and the  existence of any claim or cause of action of the Employee  against
     the  Company,  whether  predicated  on this  Agreement  or not,  shall  not
     constitute a defense to the enforcement by the Company of these covenants.

20.  Survival.  The provisions of this Agreement will survive the termination or
     expiration  of this  Agreement  where the  intent so  indicates  they shall
     survive and all other  obligations  of the Company  and the  Employee  will
     cease on termination or expiration of this Agreement.  Notwithstanding  the
     foregoing,  the Company and the Employee will remain liable for obligations
     which accrued before termination or expiration of this Agreement (including
     the Employee's  rights to be paid or reimbursed  for services  rendered and
     expenses incurred before termination or expiration of this Agreement.)

21.  Entire Agreement. This Agreement,  together with the agreements in the form
     attached as Exhibits hereto and all other exhibits and attachments  hereto,
     constitutes the final written  expression of all of the agreements  between
     the parties  with  respect to the subject  matter  hereof,  supersedes  all
     correspondence, understandings, discussions and negotiations concerning the
     matters specified herein, and specifically supersedes in its entirety other
     agreements between Company and Employee.  No addition to or modification of
     any provision of this Agreement shall be binding upon any party unless made
     in writing and signed by the party to be bound.

IN WITNESS  WHEREOF,  the undersigned have executed and delivered this Agreement
on the date written above.

                              EMPLOYMENT AGREEMENT

This Employment  Agreement (the "Agreement") is dated as of 11 June 1997 between

NOW,  THEREFORE,  in  consideration  of  the  mutual  promises  of  the  parties
hereinafter  contained,  and for  other  good and  valuable  consideration,  the
receipt and adequacy of which is hereby acknowledged, Company and Employee agree
as follows:

1.   EMPLOYMENT.  Company  hereby  employs the Employee and the Employee  hereby
     accepts  employment  upon  the  terms  and  conditions  set  forth  in this
     Agreement.  Employee  will  serve as  Exigent  Chief  Technical  Officer of
     Company,  at  the  discretion  of the  Company's  Chief  Executive  Officer

2.   TERM.  Unless  sooner  terminated  as set  forth  herein,  the term of this
     Agreement  ("Term")  shall  begin on the  business  day this  Agreement  is
     executed  (the  "Commencement  Date"),  and end at  midnight  on the  third
     anniversary of the  commencement  date,  unless  extended.  The Term may be
     extended by mutual written  agreement of the Company and Employee  provided
     the  parties  shall  agree in  writing  at  least  three  months'  prior to
     expiration of the Term.

3.   COMPENSATION.

     (a)  For all services  rendered by the Employee under this  Agreement,  the
          Company  shall pay and Employee  shall accept an annual  salary of ONE
          HUNDRED THIRTY-ONE THOUSAND and NO/100 DOLLARS ($131,000) per annum or
          lesser  amount,  on a pro rata basis,  for any period less than a full
          year.  This  compensation  shall  be  payable  to  Employee  in  equal
          installments in accordance with the Company's normal pay periods,  and
          shall be subject to all appropriate withholding taxes.

          The  annual  salary  payable  to  Employee  will be  subject to upward
          adjustment as determined by Company's  management  and approved by the
          Board of Directors in the event that Company generates annual revenues
          equal to or greater than that specified in an approved three-year plan
          (the "Plan").

     (b)  In addition to the compensation provided for in Section 3(a), Employee
          shall be granted options to purchase up to 50,000 shares of the common
          stock,  $.01 par value per share, of Company (the "Common Stock"),  at
          an exercise  price of $2.25 per share or 110% of current  market value
          whichever is higher and on the terms and  conditions  described in the
          Incentive  Stock  Option  Agreement,  which  Employee  agrees to sign,
          attached  hereto  as  Exhibit  A  and  incorporated   herein  by  this
          reference.

     (c)  Provided that Employee has not been  terminated for due cause (as that
          term is defined  below in Section 8), in addition to the  compensation
          provided for in Section (3) (a) above, Company shall grant to Employee
          options to purchase an additional  65,500 shares of Common Stock at an
          exercise  price of $2.25 per  share or 110% of  current  market  value
          whichever is higher if Company  shall  receive on or prior to February
          1, 1998. (See annual Executive Incentive Plan), including

          (i)  earnings of at least $2.9 million or prorated in accordance  with
               the approved Executive Incentive Plan for 1998; or

          (ii) new funding for Company of at least  $5,000,000,  including  long
               term  (at  least  5  years)  subordinated  debt  or  equity  or a
               combination of both.

          The Board of Directors may, in its sole discretion,  award part or all
          of the options to purchase  such 65,500 shares of Common Stock even if
          none of the foregoing  conditions are achieved on or prior to February
          1, 1998. If and to the extent any such options are awarded pursuant to
          this Section 3(c),  they shall be awarded on the terms and  conditions
          described in the form of the Incentive Stock Option Agreement,  except
          that the amount of Common Stock  subject  thereto shall be adjusted to
          reflect the amount to which Employee is then entitled.

     (d)  In addition to the compensation provided for in Sections 3(a), (b) and
          (c) hereof,  Employee  shall also be entitled to the following  during

               adopted,  provided  that  Employee  will endeavor to schedule his
               vacation to avoid conflicts with his duties hereunder. During the
               term of his  employment  under the  Agreement,  Employee shall be

               66 2/3% of  Employee's  monthly  salary  to a  maximum  of $6,000
               (Company  will  continue to pay  Employee's  full  salary  during
               periods of short-term disability);

          (iv) participation  in  Company's  401(k)  plan,  on  such  terms  and

               all employees of Company;

          (v)  such other benefits, such as pension, profit sharing,  insurance,

               and

          (vi) such other benefits, if any, which the Board of Directors, in its
               sole discretion, may make available to Employee.

4.   DUTIES; AUTHORITY.

     (a)  During the Term,  Employee  shall  perform those  services  reasonably
          requested by his  immediate  manager and the CEO in a manner and to an
          extent  which  will  allow the  Company  to  benefit  from  Employee's
          experience  in and  knowledge  of the industry in which the Company is
          engaged  and as  specified  in  greater  detail in  Exhibit B attached
          hereto and  incorporated  herein by this  reference.  During the Term,
          Employee shall devote his full professional time, attention, skill and
          energy to the  business,  welfare  and affairs of the  Company.  While
          serving as Exigent Chief  Technical  Officer,  Employee shall have the
          authority and  responsibility  to devise and implement  strategies and
          operations  and to  supervise  and  manage  all  employees  in his/her
          business unit as shown on the corporate  organizational chart approved
          by the  Board of  Directors  on June 11,  1997  which is set  forth as
          Attachment 1 to Exhibit B. Such organization  chart may be modified by
          the CEO in his discretion after collaboration from Employee.  Employee
          shall use his best efforts in the performance of his duties  hereunder
          and to promote the interests of the Company and its present and future
          subsidiaries and affiliates. Employee agrees to abide by all rules and
          regulations of Company as established or amended from time to time.

     (b)  The parties  agree that  Employee may not,  without the prior  written
          consent of Company,  be engaged in any other business activity without
          Company's  prior  written  consent,  whether or not such  activity  is
          pursued  for gain,  profit  or other  pecuniary  advantage;  provided,
          however,  that  subject  to  the  Non-Disclosure  and  Non-Competition
          Agreement set forth in Exhibit D.  Employee may  passively  invest his
          personal  assets  in  businesses  where  the  form or  manner  of such
          investment will not require services on the part of Employee.

5.   BUSINESS EXPENSES AND REIMBURSEMENTS. Employee shall further be entitled to
     reimbursement by Company for other ordinary and necessary business expenses
     incurred  by  Employee  in the  performance  of his duties  hereunder,  and
     further provided that:

          (a)  Each such  expenditure  is of a nature  qualifying it as a proper
               deduction  on the  federal  and state  income tax  returns of the
               Company as a business expense and not as deductible  compensation
               to the Employee; and

          (b)  Employee  furnishes the Company with  adequate  records and other
               documentary  evidence  required by federal and state statutes and
               regulations  for  the  substantiation  of  such  expenditures  as
               deductible business expenses of the Company and not as deductible
               compensation to the Employee.

          Employee agrees that if, at any time, any payment made to the Employee
          by the Company as a business  expense  reimbursement  for a particular
          item  shall be  disallowed  in whole as a  deductible  expense  to the
          Company  by  the  appropriate  taxing   authorities,   Employee  shall
          reimburse  Company  to the  full  extent  of such  disallowance  if so
          requested by the Company in writing.

6.   PROPRIETARY  INFORMATION  AND INVENTIONS  AGREEMENT.  As a condition to his
     employment  hereunder,  Employee agrees to execute and deliver to Company a

     employment  hereunder,  Employee  agrees to  execute  and to deliver to the
     Company a Non-Disclosure and Non-Competition Agreement in the form attached
     hereto as Exhibit D and incorporated herein by this reference.

8.   TERMINATION.

     (a)  This  Agreement  may be  terminated at any time prior to expiration of
          the Term (i) by Employee upon sixty (60) days' prior written notice to
          the Company,  (ii) upon the disability  (defined to mean the inability
          of Employee to engage in  substantial  employment  duties by reason of
          any  medically  determinable  physical  or  mental  impairment  for  a
          continuous  period of 60 days) of  Employee,  (iii) by the Company for
          "due cause" at any time (iv) by the Company without "due cause" at any

          8(a)(iii),  the Company  shall not be obligated to make any  severance
          payments or any other further payments hereunder,  except with respect
          to accrued but unpaid  compensation and  reimbursements  owed Employee
          for expenses incurred prior to the effective date of termination.  For
          purposes of Section 8, "due  cause"  shall mean  personal  dishonesty,
          willful  misconduct,  breach of a fiduciary  duty  involving  personal
          profit,  willful violation of any law, rule,  regulation (other than a
          law, rule or regulation relating to offenses or misdemeanors unrelated
          to any of the foregoing or to the  Company's  business) or final cease
          and  desist  order,  or  material  breach  of any  provision  of  this
          Agreement,  including but not limited to Employee's  obligations under

          attached  hereto  as  Exhibit  C  or  under  the   Non-Disclosure  and
          Non-Competition Agreement attached hereto as Exhibit D.

     (c)  In the  event  of  termination  by the  Company  pursuant  to  Section
          8(a)(iv) (i.e., without due cause), then in addition to any amounts to
          which Employee is entitled under Section 8(b),  Employee shall also be
          entitled to receive severance pay as follows:

          (i)  If Employee is so  terminated  without due cause within the first
               twelve  months of the Term  ("First  Year"),  an amount  equal to
               eighteen (18) months' salary, based on the then current salary of
               Employee  as of the  effective  date of  termination,  payable in
               equal  installments  in  accordance  with  Company's  normal  pay
               periods  for  Employee  (i.e.   weekly,   bi-weekly  or  monthly)
               beginning one pay period after the effective date of termination;

          (ii) If Employee is so terminated  without due cause within the second
               twelve  months of the Term  ("Second  Year"),  an amount equal to

               periods for Employee beginning one pay period after the effective
               date of termination;

          (iii)If Employee is so  terminated  without due cause within the third
               twelve months of the Term ("Third Year"),  an amount equal to six
               (6) months' salary,  based on the then current salary of Employee
               as of  the  effective  date  of  termination,  payable  in  equal
               installments in accordance with Company's  normal pay periods for
               Employee  beginning  one pay period after the  effective  date of
               termination; and

          (iv) If  Employee is still  employed by Company  after the Third Year,
               and (in the absence of any superseding  arrangement with Company,
               whether pursuant to renewal of this Agreement or otherwise) is so
               terminated  without  due  cause,  an  amount  equal to three  (3)
               months'  salary,  based on the then current salary of Employee as
               of  the  effective   date  of   termination,   payable  in  equal
               installments in accordance with Company's  normal pay periods for
               Employee  beginning  one pay period after the  effective  date of
               termination.

     (d)  In the  event  of  termination  by the  Company  pursuant  to  Section
          8(a)(iv) (i.e. without due cause),  Employee shall also be entitled to
          receive,  at his option and upon his written  request,  group  medical
          insurance as described in Section  3(d)(ii) during the period Employee
          is entitled  to receive  severance  pay under  Section  8(d) plus,  if
          applicable,    any    additional    extension   of   the    applicable
          "Non-Competition   Period"  (as  defined  in  the  Non-Disclosure  and
          Non-Competition   Agreement,   pursuant   to  Section   3(g)  of  such
          agreement).

     (e)  In the event of termination  upon  Employee's  disability  pursuant to
          Section 8(a)(ii),  the Company agrees to continue  Employee's  regular
          salary  payments  from the date of  termination  through  the date the
          insurance company commences long term disability insurance payments or
          denies coverage.  In the event long term disability coverage is denied
          due to admitted or proven fraud on behalf of the Employee, the Company
          will have no severance payment obligations to Employee. If coverage is
          denied for any other reason, Employee's termination will be treated as
          termination without due cause under Section 8(a)(iv) and Employee will
          be entitled to  severance  pay under  Section  8(c)  provided any such
          regular salary payments made by Company to Employee under this Section
          8(e) will be credited against Company's severance payment obligations.

     (f)  Notwithstanding  anything to the contrary set forth in this Agreement,
          in the event that Employee  dies during the Term of this  Agreement or
          any extension thereof, this Agreement shall terminate upon the date of
          such death,  provided that in the event of Employee's death during the
          Term of this  Agreement  or any  extension  thereof the Company  shall
          continue  to pay  Employee's  salary for a period of ninety  (90) days
          following  the date of death to the executor or  administrator  of the
          Employee's estate,  except in no event shall the Company be liable for
          the  payment of any such  death  benefit  which  exceeds  the  maximum
          severance payment obligations pursuant to Section 8(e) above.

     and assigns, if any.  Notwithstanding  anything contained in this Agreement
     to the  contrary,  nothing in this  Agreement,  expressed  or  implied,  is
     intended  to confer on any person  other than the  parties  hereto or their

     of this  Agreement,  and the terms of any agreement  attached  hereto as an
     Exhibit, to the best of his actual knowledge, will not breach any agreement

     obligations under this Agreement,  and any agreement  attached hereto as an
     Exhibit  or  any  other  exhibit  or  attachment  hereto,  will  result  in

     necessity  of posting  bond or other  security  therefor  and  without  the
     necessity of proving irreparable harm, and to such other and further relief
     as may be  proper.  Employee  hereby  submits  to the  jurisdiction  of the
     preceding courts for the purposes of any actions or proceedings  instituted
     by the  Company to obtain  such  injunctive  relief,  and  agrees  that the
     process may be served on the Employee by registered mail,  addressed to the
     last  address  of the  Employee  known  to the  Company,  or in any  manner
     authorized by law.

15.  SEVERABILITY.  If  for  any  reason  whatsoever,  any  one or  more  of the
     provisions  of this  Agreement  shall be held or deemed to be  inoperative,
     unenforceable or invalid as applied to any particular case or in all cases,
     such  circumstances  shall not have the effect of rendering  such provision
     invalid in any other case or of rendering  any of the other  provisions  of
     this Agreement inoperative, unenforceable or invalid.

16.  ASSIGNABILITY.  By reason of the special and unique  nature of the services
     hereunder,  it is agreed that neither party hereto may assign any interest,
     rights  or duties  which it or he may have in this  Agreement  without  the
     prior  written  consent of the other  party,  except  that upon any merger,
     liquidation,  or  sale of all or  substantially  all of the  assets  of the
     Company to another  corporation,  this Agreement shall inure to the benefit
     of and be  binding  upon the  Employee  and the  purchasing,  surviving  or
     resulting  company or corporation in the same manner and to the same extent
     as though such company or corporation were the Company.

17.  WAIVERS.  The  failure  or delay  of the  Company  at any  time to  require
     performance  by the employee of any  provision of this  Agreement,  even if
     know,  shall not affect the right of the Company to require  performance of
     that provision or to exercise any right, power or remedy hereunder, and any
     waiver by the  Company of any  breach of any  provision  of this  Agreement
     should not be construed as a waiver of any continuing or succeeding  breach
     of such  provision,  a waiver of the provision  itself,  or a waiver of any
     right,  power or remedy  under  this  Agreement.  No notice to or demand on
     Employee in any case  shall,  of itself,  entitle  Employee to any other or
     further notice or demand in similar or other circumstances.

18.  INDEMNIFICATION. Company agrees to exercise its power to indemnify Employee
     in  the  situations  provided  in  the  Company's  current  Certificate  of
     Incorporation  in its form filed with the  Secretary of State for the State
     of Delaware as of the date of this Agreement.  This  indemnification  shall
     apply even if such Certificate is later amended or deleted.

19.  COVENANTS  OF THE  ESSENCE.  The  covenants  of Employee  set forth in this
     Agreement and the other  Exhibits are the essence of this  Agreement;  they
     shall be construed as independent of any other provision in this Agreement;
     and the  existence of any claim or cause of action of the Employee  against
     the  Company,  whether  predicated  on this  Agreement  or not,  shall  not
     constitute a defense to the enforcement by the Company of these covenants.

20.  SURVIVAL.  The provisions of this Agreement will survive the termination or
     expiration  of this  Agreement  where the  intent so  indicates  they shall
     survive and all other  obligations  of the Company  and the  Employee  will
     cease on termination or expiration of this Agreement.  Notwithstanding  the
     foregoing,  the Company and the Employee will remain liable for obligations
     which accrued before termination or expiration of this Agreement (including
     the  Employee's  right to be paid or reimbursed  for services  rendered and
     expenses incurred before termination or expiration of this Agreement.)

21.  ENTIRE AGREEMENT. This Agreement,  together with the agreements in the form
     attached as Exhibits hereto and all other exhibits and attachments  hereto,
     constitutes the final written  expression of all of the agreements  between
     the parties  with  respect to the subject  matter  hereof,  supersedes  all
     correspondence, understandings, discussions and negotiations concerning the
     matters specified herein, and specifically supersedes in its entirety other
     agreements between Company and Employee.  No addition to or modification of
     any provision of this Agreement shall be binding upon any party unless made
     in writing and signed by the party to be bound.


IN WITNESS  WHEREOF,  the undersigned have executed and delivered this Agreement
on the date written above.

                                    Exhibit A
                   INCENTIVE STOCK OPTION AGREEMENT (PLAN 1Q)


     THIS AGREEMENT  dated as of the 11th day of June,  1997, (the "Grant Date")
by and between EXIGENT  INTERNATIONAL,  INC., with its principal  office at 1225
Evans Road,  Melbourne,  Florida 32904 (the  "Company"),  and William K. Presley
("Optionee").

                                   WITNESSETH:

     WHEREAS,  the Company has adopted an Incentive Stock Option Plan (the "Plan
1Q") as defined in Section 422 of the  Internal  Revenue  Code of 1986 to permit
options to purchase shares of the common stock of Exigent International, Inc. to
be granted to certain key employees of the Company or its subsidiaries; and

     WHEREAS,  the  Optionee  is a key  employee  of the  Company  or one of its
subsidiaries  and the  Company  desires  him/her to remain in such  employee  by
providing  him/her  with a means to acquire or to increase  his/her  proprietary
interest in the Company's success;

     NOW,  THEREFORE,  in consideration of the promises and of the covenants and
agreement set forth, the parties hereby mutually covenant and agree as follows:

     1.   Subject to the terms and conditions of the Plan 1Q, a copy of which is
          attached  hereto  as  Exhibit  "A" and  made a part  hereof,  and this
          Agreement,  the Company  grants to the Optionee the option to purchase
          from the  Company  all or any part of an  aggregate  number  of 50,000
          shares of Exigent  International,  Inc.'s  Common  Shares  (30,000,000
          authorized  shares,  par value  $0.01)  (hereinafter  such  shares are
          referred to as the "Optioned Shares").

     2.   The price to be paid for the  Optioned  Shares shall be Two and 25/100
          dollars  ($2.25) per share,  or 110% of current market value whichever
          is higher,  of the Optioned Shares on the Grant Date, as determined in
          good  faith  by the  President  of the  Company  who is in  charge  of
          administering  the  Plan  1Q.  However,  if  it  is  determined  by  a
          subsequent  Internal  Revenue Service audit that the fair market value
          of the stock at the time the option  was  granted  exceeded  the value
          established by the President,  then the option value shall be adjusted
          to comply with the Internal Revenue  Service's  determined fair market
          value,  and such adjusted  value shall apply to any and all subsequent
          exercise of options.

     3.   Subject  to terms and  conditions  of the Plan 1Q and this  Agreement,
          Optioned  Shares may be  purchased  pursuant to this  Agreement at any
          time and from time to time during a period of three (3) years from the
          date  hereof,  in whole or in part.  All options to purchase  Optioned
          Shares  subject to this  Agreement must be exercised on or before June
          11, 2000 at which time all unexercised options will expire.

     4.   An option may be exercised only by written notice, delivered or mailed
          by postpaid registered or certified mail addressed to the Secretary of
          the Company at the corporate  headquarters,  specifying  the number of
          Optioned Shares being purchased in cash or its equivalent. Within five
          (5) business  days  following  the date of exercise,  payment shall be
          made in full or by such  other  payment  means as  shall  be  mutually
          agreeable.  Such  purchased  shares  shall be  forthwith  delivered to
          Optionee.

     5.   (a) If the Optionee's employment with the Company or any subsidiary of
          the  Company  is  terminated  for  due  cause,  this  Agreement  shall
          terminate  simultaneously therewith and Optionee shall have no further
          right  to  exercise  an  option  thereafter.   For  purposes  of  this
          paragraph,  "due cause" shall be the same as defined in the Employment
          Agreement.

          (b)  If the  Optionee  ceases to be an  employee of the Company or any
               subsidiary   of  the  Company  for  any  reason  other  than  (1)
               termination  for due cause as set forth in paragraph  5(a) above,
               or (2) death or  disability,  the term of any option shall expire
               on a date not later than three (3) months after termination.

          (c)  If the  Optionee  ceases to be an  employee of the Company or any
               subsidiary of the Company by reason of disability or death within
               the meaning of Section  22(e)(3) of the Internal  Revenue Code of
               1986,  as amended,  the term of any option shall expire on a date
               which is not later than twelve (12) months  following the date of
               death or disability.

     6.   The options herein granted shall not be  transferable  by the Optionee
          otherwise  than by will or the laws of descent and  distribution,  and
          may be exercised during the life of the Optionee only by the Optionee,
          except as set forth in 5( c) above.

     7.   If any  change  is made in the  shares  subject  to the Plan 1Q or any
          option   granted    thereunder    (through   merger,    consolidation,
          reorganization,  recapitalization,  or change in  capital  structure),
          appropriate  adjustment  shall be made by the Company in the number of
          shares and kind of common  stock for which  options may be or may have
          been  granted  under the Plan 1Q,  to the end that  such  proportional
          interest  shall be  maintained  as before  the  occurrence  of such an
          event.

     8.   (a) Optionee  acknowledges  and  understands  that the Optioned Shares
          have not been registered  with the Securities and Exchange  Commission
          under the  Securities  Act of 1933,  as amended,  in reliance upon the
          exemption from  registration  provided in Regulation D of the Act, nor
          with any  state  securities  regulatory  authority  in  reliance  upon
          particular  statutory  transactional  exemptions.  As such, the shares
          purchased  under  this  Agreement,   if  exercised,   cannot  be  sold
          subsequently or otherwise  transferred  without prior (1) registration
          under the Act and under  applicable  state  law or (2)  receipt  of an
          opinion of counsel  for the  issuer to the effect  that such  proposed
          sale or other  transfer  does not  affect  the  exempt  status  of the
          original  issuance and sale of these shares and is in compliance  with
          all applicable state and federal securities laws.

          (b)  That  Optionee  will be  acquiring  the  stock  for  his/her  own
               investment  and personal  interest in the Company and not for the
               account of any other person, with no intention on his/her part of
               affecting a redistribution of such stock or any part thereof.

          (c)  That  Optionee  has asked  questions  and received all answers to
               information  he/she  considers  pertinent to form a knowledgeable
               opinion about his investment.

          (d)  That the Optionee  understands and acknowledges that he/she shall
               not be deemed for any purpose to be a shareholder  of the Company
               with respect to any of the Optioned Shares,  except to the extent
               that the options  herein  granted shall have been  exercised with
               respect thereto and a stock certified issued therefor.

          (e)  That the existence of the options herein granted shall not affect
               in any way the right or power of Exigent  International,  Inc. to
               make  or  authorize  any or all  adjustments,  recapitalizations,
               reorganizations, or other changes in Exigent International Inc.'s
               capital structure or its business, or any merger or consolidation
               of the Company or Exigent  International,  Inc.,  or any issue of
               bonds,  debentures,  preferred or prior preference stock ahead of
               or affecting the common shares of Exigent International,  Inc. or
               the rights  thereof,  or  dissolution  or  liquidation of Exigent
               International,  Inc.,  or any sale or transfer of all or any part
               of  their  assets  or  business  or any  other  corporate  act or
               proceeding, whether of a similar character or otherwise.

          (f)  That as a  condition  of the  granting  of the  option(s)  herein
               granted,  the Optionee agrees, for  himself/herself,  and his/her
               Personal Representative,  that any dispute or disagreements which
               may arise under or as a result of or  pursuant to this  Agreement
               shall be determined by the President in his sole discretion,  and
               that any  interpretation  by the  President  of the terms of this
               Agreement shall be final, binding and conclusive.

     9.   This  Agreement  shall not  confer  upon the  Optionee  any right with
          respect to  continuance  of  employment  by the Company or its related
          corporations,  nor shall it interfere in any way with the right of the
          Optionee's  employer to terminate  the  Optionee's  employment  at any
          time.

     10.  As used in this  Agreement,  the masculine,  feminine or neuter gender
          and the  singular  or plural  number  shall be deemed to  include  the
          others whenever the context so indicates or requires.

     11.  This  Agreement  shall be governed and  interpreted by the laws of the
          State of Florida.

     12.  This Agreement and any exhibit hereto constitutes the entire agreement
          between the parties with respect to the subject matter hereof,  and no
          change or  modification  shall be valid  unless  made in  writing  and
          signed by the party against whom such change or modification is sought
          to be enforced.

     IN WITNESS  WHEREOF,  the Company has caused this instrument to be executed
by its duly authorized officer and its corporate seal hereunto affixed,  and the
Optionee has hereunto affixed his/her hand the day and year first above written.

                                              EXIGENT INTERNATIONAL, INC.

                                    Exhibit C
                Proprietary Information and Inventions Agreement


In consideration and as a condition of my employment or continued  employment by
Exigent  International Inc. and/or by companies which it owns,  controls,  or is
affiliated with, or their successors in business (the "Company"), I hereby agree
with the Company as follows:

1.   Proprietary  Information.  I  understand  that during my  employment  I may
     produce,  obtain,  make known, or learn about certain information which has
     commercial  value in the business in which the Company is engaged and which
     is treated by the Company as  confidential.  This information may have been
     created,  discovered,  or developed by the Company or otherwise received by
     the  Company  from  third  parties  subject  to  a  duty  to  maintain  the
     confidentiality  of such  information.  All such information is hereinafter
     called "Proprietary Information."

     (a)  Proprietary  Information  Defined.  By way of  illustration,  but  not
          limitation,  "Proprietary  Information" includes trade secrets, ideas,
          processes,  formulas,  source codes,  data,  programs,  other original
          works   of   authorship,    know-how,    improvements,    discoveries,
          developments,   designs,  inventions,   techniques,  marketing  plans,
          strategies, forecasts, new products, unpublished financial statements,
          budgets,  projections,  licenses,  prices,  costs,  and  customers and
          supplier lists.

     (b)  Assignment  and Protection of  Proprietary  Information.  I understand
          that all  Proprietary  Information  shall be the sole  property of the
          Company and its assigns (or, in some cases, its clients, suppliers, or
          customers),  and the Company  and its  assigns (or in some cases,  its
          clients,  suppliers,  or  customers)  shall be the  sole  owner of all
          patents,  copyrights,  and other  rights in  connection  therewith.  I
          hereby  assign to the Company any rights I may have or acquire in such
          Proprietary  Information.  At all times,  both during my employment by
          the  Company  and after  its  termination,  I will  keep in  strictest
          confidence and trust all Proprietary Information,  and I will not use,
          reproduce, or disclose any Proprietary Information without the written
          consent of the  Company,  except as may be  necessary  in the ordinary
          course of performing my duties as an employee of the Company.

     (c)  Maintenance  of Records.  I agree to keep and  maintain  adequate  and
          current records of all proprietary information developed by me (in the
          form of  notes,  sketches,  drawings  and as may be  specified  by the
          Company)  which  records  shall be  available  to and  remain the sole
          property of the Company at all times.

2.   Inventions During and Immediately After My Term of Employment. I understand
     that during my employment or following my employment,  I may make, conceive
     of, or reduce  to  practice  various  discoveries,  developments,  designs,
     improvements,  inventions, formulas, processes, techniques, programs, other
     works of authorship,  know-how, and data (all of which shall be referred to
     as "inventions"  throughout  this  Agreement,  whether or not patentable or
     registrable under copyright, mask work, or similar statutes).

     (a)  Assignment of Inventions.  I hereby assign and transfer to the Company
          my entire right,  title, and interest in and to all inventions made or
          conceived  or reduced to practice by me,  either alone or jointly with
          others,  during the period of my employment  with the Company,  except
          for those  inventions  which I have developed  entirely on my own time
          without using the Company's equipment,  supplies, facilities, or trade
          secret information  excluding those inventions that either: (1) relate
          at the time of conception or reduction to practice of the invention to
          the  business,  or  actual or  demonstrably  anticipated  research  or
          development  of the Company;  or (2) result from any work performed by
          me  for  the  Company.  I  acknowledge  that  all  original  works  of
          authorship which are made by me (solely or jointly with others) within
          the scope of my employment and which are  protectable by copyright are
          "works  made for hire," as that term is defined in the U.S.  Copyright
          Act as in effect as of this date. I will,  at the  Company's  request,
          promptly execute a written  assignment of title to the Company for any
          such invention and I will preserve any such invention as  confidential
          information of the Company.

          Notwithstanding  the foregoing,  I also hereby assign and transfer to,
          or as directed  by, the Company all my right,  title,  and interest in
          and to any and all  inventions,  full title to which is required to be
          in the United States by a contract  between the Company and the United
          States or any of its agencies.

     (b)  Maintenance  of Records.  I agree to keep and  maintain  adequate  and
          current  records of all  inventions  made by me (in the form of notes,
          sketches,  drawings  and as may be  specified  by the  Company)  which
          records  shall be  available  to and remain the sole  property  of the
          Company at all times.

     (c)  Disclosure of Inventions.  I will promptly  disclose in writing to the
          Company all inventions made or conceived or reduced to practice by me,
          either  alone  or  jointly  with  others,  during  the  period  of  my
          employment, and for six months after termination of my employment with
          the Company.

     (d)  Execution of Documents. I further agree as to all inventions to assist
          the  Company in every  proper way (but at the  Company's  expense)  to
          obtain and from time to time enforce patents,  copyrights, mask works,
          and other rights and protections relating to inventions in any and all
          countries,  and to that end I will  execute all  documents  for use in
          applying for and obtaining such patents,  copyrights,  mask works, and
          other  rights  and  protections  on and  enforcing  inventions  as the
          Company  may  desire,  together  with any  assignments  thereof to the
          Company  or  persons  designated  by it. My  obligation  to assist the
          Company in obtaining and enforcing  patents,  copyrights,  mask works,
          and other rights and protections relating to inventions in any and all
          countries shall continue beyond the termination of my employment,  but
          the  Company  shall  compensate  me at a  reasonable  rate  after such
          termination for time actually spent by me at the Company's  request on
          such assistance.  In the event the Company is unable, after reasonable
          effort,  to secure my signature on any document or documents needed to
          obtain or enforce any patent,  copyright, mask work, or other right or
          protection relating to any inventions,  whether because of my physical
          or mental  incapacity  or for any other  reason  whatsoever,  I hereby
          irrevocably  designate and appoint the Company and its duly authorized
          officers and agents as my agent and  attorney-in-fact,  to act for and
          in my  behalf  and  stead  to  execute  and file  any  application  or
          assignment and to do all other lawfully  permitted acts to further the
          prosecution and issuance to the Company of patents,  copyrights,  mask
          works,  or similar  protections  thereon with the same legal force and
          effect as if executed by me.

3.   Prior  Inventions.  I understand that all inventions,  if any,  patented or
     unpatented,  which  I made  prior  to my  employment  by the  Company,  are
     excluded  from the  scope  of this  Agreement.  To  preclude  any  possible
     uncertainty,  I have set forth in Item 1 of Exhibit A  attached  hereto and
     made a part hereof a complete list of all of my prior inventions, including
     numbers of all patents and patent applications,  and a brief description of
     unpatented  inventions which are not the property of a previous employer. I
     represent  and covenant that the list is complete and that, if no items are
     on the list, I have no such prior inventions. I agree to notify the Company
     in writing  before I make any  disclosure  or perform any work on behalf of
     the Company which appears to threaten or conflict with proprietary rights I
     claim in any  invention  or idea.  In the event of my  failure to give such
     notice,  I agree that I will make no claim against the Company with respect
     to any such inventions or ideas.

4.   Conflicting Employment Obligations.

     (a)  Trade Secrets of Others.  I represent that I have not brought and will
          not  bring  with me to the  Company  or use in the  performance  of my
          responsibilities at the Company any devices,  materials,  or documents
          of a former  employer that are not generally  available to the public,
          unless I have obtained express written  authorization  from the former
          employer for their  possession  and use. The only devices,  materials,
          documents of a former employer that are not generally available to the
          public  that I will bring to the Company or use in my  employment  are
          identified on Item 2 of Exhibit A attached hereto, and as to each such
          item, I represent that I have obtained  express written  authorization
          for their  possession and use in employment  with the Company and have
          delivered a copy of such written authorization to the Company.

          (The Confidential  Business  Information and Confidential  Proprietary

Company,  including extended periods under Section 4(f) herein, and (ii) for one
year  thereafter,  reveal  to any  person,  association  or  company  any of the
Company's  Confidential  Business  Information,  so  far  as  such  Confidential
Business  Information  has come or may come to his  knowledge,  except as may be
required in the ordinary  course of  performing  his duties as an officer of the
Company or as may be in the public domain through no fault of Employee or as may
be required by law.

     (c) Employee hereby agrees that he will not at any time,  whether during or
after the  termination of his employment,  reveal to any person,  association or
company any of the Company's Confidential Proprietary Information,  so far as to
his  knowledge,  except as may be required in the ordinary  course of performing
his  duties as an  officer  of the  Company  or as may be in the  public  domain
through no fault of Employee or as may be required by law.

     (d) Employee  agrees to keep in  confidence  and secret all matters of such
nature  entrusted  to him and he  shall  not  use or  attempt  to use  any  such
information in any manner which may injure or cause loss to the Company, whether

     (e) Employee  acknowledges  the  critical  importance  of the  Confidential
Information  to  the  Company's   business   operations   and  plans.   Employee
acknowledges  that  unauthorized  disclosure  or use of any of the  Confidential
Information (in particular trade secrets and technical proprietary  information)
would  cause  significant  and  irreparable  damage  to the  Company  and  would
jeopardize the Company's business and financial condition.

     (f) Nothing  herein shall be construed as granting to Employee any right or
license under any copyrights,  inventions,  or patents now or hereafter owned or
controlled by the Company or any right to employment by the Company.

     (g) In the  event  Employee's  employment  is  terminated  for any  reason,
Employee shall return all Confidential  Information in his possession,  together
with any copies, to the Company.

3.   NON-COMPETITION.  Employee  agrees and  acknowledges  that the products and
     services to be sold and rendered by the Company are  different in character
     and are of particular  significance to the Company, and that the Company is
     in a competitive business. Due to the proprietary and specialized nature of
     the Company's business, Employee agrees to the following:

     (a)  During  his   employment   and   thereafter   during  the   applicable
"Non-Competition  Period"  (as  defined in  Section  3(e))  Employee  shall not,
directly or indirectly,  induce, influence, combine or conspire with, or attempt
to induce, influence,  combine or conspire with, any of the officers,  employees
or consultants of the Company to terminate their employment or relationship with
the Company.

     (b)  During  his   employment   and   thereafter   during  the   applicable
"Non-Competition  Period"  (as  defined in Section  3(e)),  Employee  shall not,
directly or indirectly,  induce,  or attempt to induce,  any of the customers or
suppliers of the Company to terminate their relationship with the Company.

     (c)  During  his   employment   and   thereafter   during  the   applicable
"Non-Competition  Period (as defined in Section 3(e)),  Employee  agrees that he
will not voluntarily or involuntarily,  for any reason  whatsoever,  directly or
indirectly,  individually  or on  behalf  of  persons  not now  parties  to this
Agreement, or as a partner,  stockholder,  director,  officer, principal, agent,
broker, licensor, employee, or in any other capacity or relationship,  engage in
any business or  employment,  or aid or endeavor to assist any business or legal
entity,  which  is in  competition  with the  products  and/or  services  of the
Company;  provided,  however,  this  Section 3(c) shall not be deemed to prevent
Employee from working after termination of the applicable Non-Competition Period
in any areas or  division  within the  applicable  industry.  The  ownership  by
Employee  of not  more  than  five  percent  (5%)  of  shares  of  stock  or any
corporation  having a class or equity  securities  actively traded on a national
securities  exchange or NASDAQ shall not be deemed, in and of itself, to violate
this Section 3(c).

     (d)  Employee  agrees  not to do or say  anything  that  reasonably  may be
expected  to have the  effect of  disparaging  the  Company  or  diminishing  or
impairing  the  goodwill  and  reputation  of the  Company  and the  services it
provides. Likewise, the Company agrees not to do or say anything that reasonably
may be expected to have the effect of disparaging the Employee or diminishing or
impairing the reputation of the Employee.

     (e) If, in any judicial  proceedings a court shall refuse to enforce any of
the  other   separate   covenants  set  forth  in  this  Section  3,  then  such
unenforceable  covenant  shall be  amended  to relate to such  lesser  period or
geographical  areas as shall be  enforceable  or, if deemed  appropriate by such
court,  deemed  eliminated  from  these  provisions  for the  purpose  of  those
proceedings to the extent necessary to permit the remaining  separate  covenants
to be enforced.

     (f) Under the terms of the  Employment  Agreement,  Employee is entitled to
receive  severance pay in the event his  employment is terminated by the Company
without due cause.  In the event  Employee's  employment is  terminated  for any
reason whatsoever,

          (i)  during  the first  year of his  employment,  then the  applicable
     Non-Competition  Period for Section 3(a), (b) and (c) will be eighteen (18)
     months; or

          (ii) during the second  year of his  employment,  then the  applicable
     Non-Competition  Period for Section  3(a),  (b) and (c) will be twelve (12)
     months; or

          (iii)  during the third year of his  employment,  then the  applicable
     Non-Competition  Period  for  Section  3(a),  (b) and  (c)  will be six (6)
     months; or

          (iv) by  expiration  of the Term or  otherwise,  at any time after the
     third  anniversary of his employment,  then the applicable  Non-Competition
     Period for Sections 3(a), (b) and (c) will be three (3) months.

     (g) Notwithstanding the foregoing, the Company may, at its option, elect to
extend the  applicable  Non-Competition  Period by up to twelve (12)  additional
months by payment to Employee of additional severance pay equal to his salary in
effect  at the date of  termination  of his  employment  for such  time  period.
Payments will be made in accordance with the Company's normal pay periods for as
long as the Company  elects to so extend the  Non-Competition  Period.  Employee
hereby agrees to accept such payments as compensation  for such extension of the
applicable Non-Competition Period.

     (h) Company and Employee hereby acknowledge that:

          (i) Company's market for its products is unlimited  geographically and
     the foregoing  noncompetition  and  non-solicitation  requirements shall be
     applied on a worldwide basis;

          (ii) the duration and geographical limitations imposed with respect to
     said noncompetition and non-solicitation requirements are reasonable;

          (iii) the restrictions stated hereinabove are reasonably necessary for
     the protection of Company's legitimate proprietary interests.

     (i)  Employee   represents   and  warrants  that  his/her   experience  and
capabilities  are such that the restrictive  covenants set forth herein will not
prevent him/her from earning his/her  livelihood and that Employee will be fully
able to earn an adequate  livelihood for  himself/herself and his/her dependents
if any such provisions should be specifically enforced against Employee.

     (j) The non-competition and non-solicitation  obligations  contained herein
shall be extended by the length of time during which Employee shall have been in
breach of any said  provisions  and during any time the  Company is  required to
seek compliance by judicial proceeding.

4.   SPECIFIC  REMEDIES.  In addition  to any other  remedy  provided  herein or
     contemplated under law, and not as liquidated damages, in the even Employee
     breaches  any  material  covenant  of  this  Agreement,  such  breach  will
     constitute  "due  cause"  for  termination  of  his  employment  under  the
     Employment  Agreement  and the  Company  shall have the right,  but not the
     obligation,   to  purchase  from  Employee  and  Employee  shall  have  the
     obligation  to sell to the Company any or all of the shares of Common Stock
     of the  Company  at a  purchase  price  equal to  Employee's  cost for such
     shares.  Such right shall be exercised by written notice to Employee within
     sixty  (60)  days  of  establishment  by  consent,   judicial  decision  or
     arbitration  that  Employee so breached this  Agreement.  Any of Employee's
     permitted transferees will be obligated to sell to the Company Common Stock
     shares of the Company held by them in the event the Company  exercises this
     right to purchase.

<PAGE>
                                   Exhibit E
                     CONFIDENTIAL NATURE OF COMPANY AFFAIRS


PURPOSE:

It is the policy of  Exigent  International  Inc.  (Exigent)  that the  internal
business affairs of the organization,  particularly confidential information and
trade secrets,  represent proprietary assets that each employee has a continuing
obligation to protect.

POLICY:

     1.   CONFIDENTIAL INFORMATION. Information designated as confidential is to
          be discussed with no one outside the  organization  and only discussed
          within  the  organization  on a "need to  know"  basis.  In  addition,
          employees have a  responsibility  to avoid  unnecessary  disclosure of
          nonconfidential internal information about Exigent, its customers, and
          its suppliers.  This  responsibility  is not intended to impede normal
          business  communications and  relationships,  but is intended to alert
          employees to their obligations to use discretion to safeguard internal
          Exigent affairs.

     2.   VIOLATION OF UNAUTHORIZED ACCESS.  Employees authorized to have access
          to confidential  information must treat the information as proprietary
          Exigent property for which they are personally responsible.  Employees
          are prohibited from attempting to obtain confidential  information for
          which they have not received  authorization.  Employees violating this

          Board of Directors that  Employee's  employment  should be terminated,
          the Company  agrees that  termination  in such  circumstances  will be
          deemed terminated by the Company without "due cause."

          (iv) If  Employee is still  employed by Company  after the Third Year,
               and (in the absence of any superseding  arrangement with Company,
               whether pursuant to renewal of this Agreement or otherwise) is so
               terminated  without  due  cause,  an  amount  equal to three  (3)

     (e)  In the  event  of  termination  by the  Company  pursuant  to  Section
          8(a)(iv),  or Section 8(c) (i.e.  without due cause),  Employee  shall

          during the period Employee is entitled to receive  severance pay under

          insurance company commences long term disability insurance payments or

          due to admitted or proven fraud on behalf of the Employee, the Company
          will have no severance payment obligations to Employee. If coverage is
          denied for any other reason, Employee's termination will be treated as
          termination without due cause under Section 8(a)(iv) and Employee will
          be entitled to  severance  pay under  Section  8(d)  provided any such
          payments  made by Company to Employee  under this Section 8(f) will be
          credited against Company's severance payment obligations.

     (g)  Notwithstanding  anything to the contrary set forth in this Agreement,
          in the event that Employee  dies during the Term of this  Agreement or
          any extension thereof, this Agreement shall terminate upon the date of
          such death,  provided that in the event of Employee's death during the
          Term of this  Agreement  or any  extension  thereof the Company  shall
          continue  to pay  Employee's  salary for a period of ninety  (90) days
          following  the date of death to the executor or  administrator  of the
          Employee's estate,  except in no event shall the Company be liable for
          the  payment of any such  death  benefit  which  exceeds  the  maximum
          severance payment obligations pursuant to Section 8(e) above.

     inure to the benefit of this parties hereto and their respective successors
     and assigns, if any.  Notwithstanding  anything contained in this Agreement
     to the  contrary,  nothing in this  Agreement,  expressed  or  implied,  is
     intended  to confer on any person  other than the  parties  hereto or their
     respective  heirs,  successors,  executors,  administrators  or assigns any
     rights,  remedies,  obligations or  liabilities  under or by reason of this
     Agreement.

     accordance  with  the  internal  laws  of the  State  of  Florida,  without
     reference to principles of conflict of laws.

12.  Headings.   Headings  of  the  Sections  of  this  Agreement  are  for  the
     convenience  of the  parties  only,  and shall be given no  substantive  or
     interpretive effect whatsoever.

13.  No Conflict. Employee represents and warrants that performance of the terms
     of this  Agreement,  and the terms of any agreement  attached  hereto as an
     Exhibit, to the best of his actual knowledge, will not breach any agreement
     entered into by Employee,  and Employee  agrees that he will not enter into
     any agreement in conflict with this Agreement and the  agreements  attached
     as  Exhibits.  Employee  further  covenants  that (i) he  shall  not in the
     performance  of his duties  hereunder  (and the  performance of such duties
     shall  not  require  him  to)  utilize  any   proprietary  or  confidential
     information  owned by any third party which he is prohibited from utilizing
     by reason of agreement or applicable law, and (ii) he shall not at any time
     disclose to Company any  proprietary or confidential  information  owned by
     any  third  party  which he is  prohibited  from  disclosing  by  reason of

14.  Injunctive  Relief.  Employee  acknowledges and agrees that a breach of his
     obligations under this Agreement,  and any agreement  attached hereto as an
     Exhibit  or  any  other  exhibit  or  attachment  hereto,  will  result  in
     irreparable and continuing harm to the Company,  for which there will be no
     adequate  remedy at law,  and  agrees  that in the  event of any  breach or
     prospective  breach of this  Agreement,  the Company,  its  successors  and
     assigns will be entitled to injunctive relief in any federal or state court
     of  competent  jurisdiction  residing  in the State of Florida  without the
     necessity  of posting  bond or other  security  therefor  and  without  the
     necessity of proving irreparable harm, and to such other and further relief
     as may be  proper.  Employee  hereby  submits  to the  jurisdiction  of the
     preceding courts for the purposes of any actions or proceedings  instituted
     by the  Company to obtain  such  injunctive  relief,  and  agrees  that the
     process may be served on the Employee by registered mail,  addressed to the
     last  address  of the  Employee  known  to the  Company,  or in any  manner
     authorized by law.

15.  Severability.  If  for  any  reason  whatsoever,  any  one or  more  of the
     provisions  of this  Agreement  shall be held or deemed to be  inoperative,
     unenforceable or invalid as applied to any particular case or in all cases,
     such  circumstances  shall not have the effect of rendering  such provision
     invalid in any other case or of rendering  any of the other  provisions  of
     this Agreement inoperative, unenforceable or invalid.

16.  Assignability.  By reason of the special and unique  nature of the services
     hereunder,  it is agreed that neither party hereto may assign any interest,
     rights  or duties  which it or he may have in this  Agreement  without  the
     prior  written  consent of the other  party,  except  that upon any merger,
     liquidation,  or  sale of all or  substantially  all of the  assets  of the
     Company to another  corporation,  this Agreement shall inure to the benefit
     of and be  binding  upon the  Employee  and the  purchasing,  surviving  or
     resulting  company or corporation in the same manner and to the same extent
     as though such company or corporation were the Company.

17.  Waivers.  The  failure  or delay  of the  Company  at any  time to  require
     performance  by the employee of any  provision of this  Agreement,  even if
     know,  shall not affect the right of the Company to require  performance of
     that provision or to exercise any right, power or remedy hereunder, and any
     waiver by the  Company of any  breach of any  provision  of this  Agreement
     should not be construed as a waiver of any continuing or succeeding  breach
     of such  provision,  a waiver of the provision  itself,  or a waiver of any
     right,  power or remedy  under  this  Agreement.  No notice to or demand on
     Employee in any case  shall,  of itself,  entitle  Employee to any other or
     further notice or demand in similar or other circumstances.

18.  Indemnification. Company agrees to exercise its power to indemnify Employee
     in  the  situations  provided  in  the  Company's  current  Certificate  of
     Incorporation  in its form filed with the  Secretary of State for the State
     of Delaware as of the date of this Agreement.  This  indemnification  shall
     apply even if such Certificate is later amended or deleted.

19.  Covenants  of the  Essence.  The  covenants  of Employee  set forth in this
     Agreement and the other  Exhibits are the essence of this  Agreement;  they
     shall be construed as independent of any other provision in this Agreement;
     and the  existence of any claim or cause of action of the Employee  against
     the  Company,  whether  predicated  on this  Agreement  or not,  shall  not
     constitute a defense to the enforcement by the Company of these covenants.

20.  Survival.  The provisions of this Agreement will survive the termination or
     expiration  of this  Agreement  where the  intent so  indicates  they shall
     survive and all other  obligations  of the Company  and the  Employee  will
     cease on termination or expiration of this Agreement.  Notwithstanding  the
     foregoing,  the Company and the Employee will remain liable for obligations
     which accrued before termination or expiration of this Agreement (including
     the  Employee's  right to be paid or reimbursed  for services  rendered and
     expenses incurred before termination or expiration of this Agreement.)

21.  Entire Agreement. This Agreement,  together with the agreements in the form
     attached as Exhibits  hereto,  constitutes the final written  expression of
     all of the  agreements  between  the  parties  with  respect to the subject
     matter hereof, supersedes all correspondence,  understandings,  discussions
     and negotiations  concerning the matters specified herein, and specifically
     supersedes in its entirety other  agreements  between Company and Employee.
     No addition to or  modification of any provision of this Agreement shall be
     binding upon any party unless made in writing and signed by the party to be
     bound.

IN WITNESS  WHEREOF,  the undersigned have executed and delivered this Agreement
on the date written above.

                                    Exhibit A
                   INCENTIVE STOCK OPTION AGREEMENT (PLAN 1Q)


     THIS AGREEMENT  dated as of the 11th day of June,  1997, (the "Grant Date")
by and between EXIGENT  INTERNATIONAL,  INC., with its principal  office at 1225
Evans Road,  Melbourne,  Florida 32904 (the  "Company"),  and Bernard R. Smedley
("Optionee").

                                   WITNESSETH:

     WHEREAS,  the Company has adopted an Incentive Stock Option Plan (the "Plan
1Q") as defined in Section 422 of the  Internal  Revenue  Code of 1986 to permit
options to purchase shares of the common stock of Exigent  International,  Inc.,
to be granted to certain key employees of the Company or its subsidiaries; and

     WHEREAS,  the  Optionee  is a key  employee  of the  Company  or one of its
subsidiaries  and the  Company  desires  him/her to remain in such  employee  by
providing  him/her  with a means to acquire or to increase  his/her  proprietary
interest in the Company's success;

     NOW,  THEREFORE,  in consideration of the promises and of the covenants and
agreement set forth, the parties hereby mutually covenant and agree as follows:

     1.   Subject to the terms and conditions of the Plan 1Q, a copy of which is
          attached  hereto  as  Exhibit  "A" and  made a part  hereof,  and this
          Agreement,  the Company  grants to the Optionee the option to purchase
          from the  Company  all or any part of an  aggregate  number of 125,000
          shares of Exigent  International,  Inc.'s  Common  Shares  (30,000,000
          authorized  shares,  par value  $0.01)  (hereinafter  such  shares are
          referred to as the "Optioned Shares").

     2.   The price to be paid for the  Optioned  Shares shall be Two and 25/100
          dollars  ($2.25) per share,  or 110% of current market value whichever
          is higher,  of the Optioned Shares on the Grant Date, as determined in
          good  faith  by the  President  of the  Company  who is in  charge  of
          administering  the  Plan  1Q.  However,  if  it  is  determined  by  a
          subsequent  Internal  Revenue Service audit that the fair market value
          of the stock at the time the option  was  granted  exceeded  the value
          established by the President,  then the option value shall be adjusted
          to comply with the Internal Revenue  Service's  determined fair market
          value,  and such adjusted  value shall apply to any and all subsequent
          exercise of options.

     3.   Subject  to terms and  conditions  of the Plan 1Q and this  Agreement,
          Optioned  Shares may be  purchased  pursuant to this  Agreement at any
          time and from time to time during a period of three (3) years from the
          date  hereof,  in whole or in part.  All options to purchase  Optioned
          Shares  subject to this  Agreement must be exercised on or before June
          11, 2000 at which time all unexercised options will expire.

     4.   An option may be exercised only by written notice, delivered or mailed
          by postpaid registered or certified mail addressed to the Secretary of
          the Company at the corporate  headquarters,  specifying  the number of
          Optioned  Shares  being  purchased in cash or its  equivalent.  Within
          three (3) business days following the date of exercise,  payment shall
          be made in full or by such other  payment  means as shall be  mutually
          agreeable.  Such  purchased  shares  shall be  forthwith  delivered to
          Optionee.

     5.   (a) If the Optionee's employment with the Company or any subsidiary of
          the  Company  is  terminated  for  due  cause,  this  Agreement  shall
          terminate  simultaneously therewith and Optionee shall have no further
          right  to  exercise  an  option  thereafter.   For  purposes  of  this
          paragraph,  "due cause" shall be the same as defined in the Employment
          Agreement.

          (b)  If the  Optionee  ceases to be an  employee of the Company or any
               subsidiary   of  the  Company  for  any  reason  other  than  (1)
               termination  for due cause as set forth in paragraph  5(a) above,
               or (2) death or  disability,  the term of any option shall expire
               on a date not later than three (3) months after termination.

          (c)  If the  Optionee  ceases to be an  employee of the Company or any
               subsidiary of the Company by reason of disability or death within
               the meaning of Section  22(e)(3) of the Internal  Revenue Code of
               1986,  as amended,  the term of any option shall expire on a date
               which is not later than twelve (12) months  following the date of
               death or disability.

     6.   The options herein granted shall not be  transferable  by the Optionee
          otherwise  than by will or the laws of descent and  distribution,  and
          may be exercised during the life of the Optionee only by the Optionee,
          except as set forth in 5( c) above.

     7.   If any  change  is made in the  shares  subject  to the Plan 1Q or any
          option   granted    thereunder    (through   merger,    consolidation,
          reorganization,  recapitalization,  or change in  capital  structure),
          appropriate  adjustment  shall be made by the Company in the number of
          shares and kind of common  stock for which  options may be or may have
          been  granted  under the Plan 1Q,  to the end that  such  proportional
          interest  shall be  maintained  as before  the  occurrence  of such an
          event.

     8.   (a) Optionee  acknowledges  and  understands  that the Optioned Shares
          have not been registered  with the Securities and Exchange  Commission
          under the  Securities  Act of 1933,  as amended,  in reliance upon the
          exemption from  registration  provided in Regulation D of the Act, nor
          with any  state  securities  regulatory  authority  in  reliance  upon
          particular  statutory  transactional  exemptions.  As such, the shares
          purchased  under  this  Agreement,   if  exercised,   cannot  be  sold
          subsequently or otherwise  transferred  without prior (1) registration
          under the Act and under  applicable  state  law or (2)  receipt  of an
          opinion of counsel  for the  issuer to the effect  that such  proposed
          sale or other  transfer  does not  affect  the  exempt  status  of the
          original  issuance and sale of these shares and is in compliance  with
          all applicable state and federal securities laws.

          (b)  That  Optionee  will be  acquiring  the  stock  for  his/her  own
               investment  and personal  interest in the Company and not for the
               account of any other person, with no intention on his/her part of
               affecting a redistribution of such stock or any part thereof.

          (c)  That  Optionee  has asked  questions  and received all answers to
               information  he/she  considers  pertinent to form a knowledgeable
               opinion about his investment.

          (d)  That the Optionee  understands and acknowledges that he/she shall
               not be deemed for any purpose to be a shareholder  of the Company
               with respect to any of the Optioned Shares,  except to the extent
               that the options  herein  granted shall have been  exercised with
               respect thereto and a stock certified issued therefor.

          (e)  That the existence of the options herein granted shall not affect
               in any way the right or power of Exigent  International,  Inc. to
               make  or  authorize  any or all  adjustments,  recapitalizations,
               reorganizations, or other changes in Exigent International Inc.'s
               capital structure or its business, or any merger or consolidation
               of the Company or Exigent  International,  Inc.,  or any issue of
               bonds,  debentures,  preferred or prior preference stock ahead of
               or affecting the common shares of Exigent International,  Inc. or
               the rights  thereof,  or  dissolution  or  liquidation of Exigent
               International,  Inc.,  or any sale or transfer of all or any part
               of  their  assets  or  business  or any  other  corporate  act or
               proceeding, whether of a similar character or otherwise.

          (f)  That as a  condition  of the  granting  of the  option(s)  herein
               granted,  the Optionee agrees, for  himself/herself,  and his/her
               Personal Representative,  that any dispute or disagreements which
               may arise under or as a result of or  pursuant to this  Agreement
               shall be determined by the President in his sole discretion,  and
               that any  interpretation  by the  President  of the terms of this
               Agreement shall be final, binding and conclusive.

     9.   This  Agreement  shall not  confer  upon the  Optionee  any right with
          respect to  continuance  of  employment  by the Company or its related
          corporations,  nor shall it interfere in any way with the right of the
          Optionee's  employer to terminate  the  Optionee's  employment  at any
          time.

     10.  As used in this  Agreement,  the masculine,  feminine or neuter gender
          and the  singular  or plural  number  shall be deemed to  include  the
          others whenever the context so indicates or requires.

     11.  This  Agreement  shall be governed and  interpreted by the laws of the
          State of Florida.

     12.  This Agreement and any exhibit hereto constitutes the entire agreement
          between the parties with respect to the subject matter hereof,  and no
          change or  modification  shall be valid  unless  made in  writing  and
          signed by the party against whom such change or modification is sought
          to be enforced.

     IN WITNESS  WHEREOF,  the Company has caused this instrument to be executed
by its duly authorized officer and its corporate seal hereunto affixed,  and the
Optionee has hereunto affixed his/her hand the day and year first above written.

                                          EXIGENT INTERNATIONAL, INC.

               PROPRIETARY INFORMATION AND INVENTIONS AGREEMENT


In consideration and as a condition of my employment or continued  employment by
Exigent  International Inc. and/or by companies which it owns,  controls,  or is
affiliated with, or their successors in business (the "Company"), I hereby agree
with the Company as follows:

1.          PROPRIETARY  INFORMATION.  I understand  that during my employment I
            may produce,  obtain, make known, or learn about certain information
            which has  commercial  value in the business in which the Company is
            engaged  and which is treated by the Company as  confidential.  This
            information may have been created,  discovered,  or developed by the
            Company or  otherwise  received  by the Company  from third  parties
            subject  to  a  duty  to  maintain  the   confidentiality   of  such
            information. All such information is hereinafter called "Proprietary
            Information."

          (a)  PROPRIETARY INFORMATION DEFINED. By way of illustration,  but not
               limitation,  "Proprietary  Information"  includes  trade secrets,
               ideas, processes,  formulas,  source codes, data, programs, other
               original   works   of   authorship,    know-how,    improvements,
               discoveries,   developments,   designs,  inventions,  techniques,
               marketing plans, strategies, forecasts, new products, unpublished
               financial statements,  budgets,  projections,  licenses,  prices,
               costs, and customers and supplier lists.

          (b)  ASSIGNMENT   AND  PROTECTION  OF   PROPRIETARY   INFORMATION.   I
               understand  that all  Proprietary  Information  shall be the sole
               property of the Company and its assigns  (or, in some cases,  its
               clients,  suppliers,  or  customers),  and  the  Company  and its
               assigns (or in some cases, its clients,  suppliers, or customers)
               shall be the sole  owner of all  patents,  copyrights,  and other
               rights in  connection  therewith.  I hereby assign to the Company
               any rights I may have or acquire in such Proprietary Information.
               At all times,  both during my employment by the Company and after
               its  termination,  I will keep in strictest  confidence and trust
               all Proprietary  Information,  and I will not use, reproduce,  or
               disclose any Proprietary  Information without the written consent
               of the Company, except as may be necessary in the ordinary course
               of performing my duties as an employee of the Company.

          (c)  MAINTENANCE OF RECORDS. I agree to keep and maintain adequate and
               current  records of all proprietary  information  developed by me
               (in the form of notes, sketches, drawings and as may be specified
               by the Company)  which  records  shall be available to and remain
               the sole property of the Company at all times.

2.          INVENTIONS  DURING AND  IMMEDIATELY  AFTER MY TERM OF EMPLOYMENT.  I
            understand  that during my employment or following my employment,  I
            may make,  conceive of, or reduce to practice  various  discoveries,
            developments,    designs,   improvements,    inventions,   formulas,
            processes,   techniques,   programs,   other  works  of  authorship,
            know-how,   and  data  (all  of  which   shall  be  referred  to  as
            "inventions" throughout this Agreement, whether or not patentable or
            registrable under copyright, mask work, or similar statutes).

          (a)  ASSIGNMENT  OF  INVENTIONS.  I hereby  assign and transfer to the
               Company  my  entire  right,  title,  and  interest  in and to all
               inventions made or conceived or reduced to practice by me, either
               alone or jointly with others,  during the period of my employment
               with  the  Company,  except  for  those  inventions  which I have
               developed  entirely on my own time  without  using the  Company's
               equipment,  supplies,  facilities,  or trade  secret  information
               excluding those inventions that either: (1) relate at the time of
               conception  or  reduction  to  practice of the  invention  to the
               business,  or  actual or  demonstrably  anticipated  research  or
               development of the Company; or (2) result from any work performed
               by me for the Company.  I acknowledge  that all original works of
               authorship  which are made by me (solely or jointly  with others)
               within the scope of my employment  and which are  protectable  by
               copyright  are "works  made for hire," as that term is defined in
               the U.S.  Copyright  Act as in effect as of this date. I will, at
               the Company's  request,  promptly execute a written assignment of
               title to the Company for any such  invention  and I will preserve
               any such invention as confidential information of the Company.

               Notwithstanding the foregoing,  I also hereby assign and transfer
               to, or as  directed  by, the  Company  all my right,  title,  and
               interest in and to any and all inventions, full title to which is
               required  to be in the United  States by a contract  between  the
               Company and the United States or any of its agencies.

          (b)  MAINTENANCE OF RECORDS. I agree to keep and maintain adequate and
               current  records  of all  inventions  made by me (in the  form of
               notes, sketches, drawings and as may be specified by the Company)
               which  records shall be available to and remain the sole property
               of the Company at all times.

          (c)  DISCLOSURE OF INVENTIONS.  I will promptly disclose in writing to
               the  Company  all  inventions  made or  conceived  or  reduced to
               practice by me,  either alone or jointly with others,  during the
               period of my employment,  and for six months after termination of
               my employment with the Company.

          (d)  EXECUTION OF DOCUMENTS.  I further agree as to all  inventions to
               assist  the  Company in every  proper  way (but at the  Company's
               expense)  to  obtain  and  from  time  to time  enforce  patents,
               copyrights, mask works, and other rights and protections relating
               to  inventions in any and all  countries,  and to that end I will
               execute all documents for use in applying for and obtaining  such
               patents, copyrights, mask works, and other rights and protections
               on and enforcing  inventions as the Company may desire,  together
               with any assignments thereof to the Company or persons designated
               by it. My  obligation  to assist  the  Company in  obtaining  and
               enforcing patents,  copyrights,  mask works, and other rights and
               protections relating to inventions in any and all countries shall
               continue beyond the termination of my employment, but the Company
               shall  compensate me at a reasonable rate after such  termination
               for time actually  spent by me at the  Company's  request on such
               assistance.  In the event the Company is unable, after reasonable
               effort,  to secure my  signature  on any  document  or  documents
               needed to obtain or enforce any patent,  copyright, mask work, or
               other right or  protection  relating to any  inventions,  whether
               because  of my  physical  or mental  incapacity  or for any other
               reason whatsoever, I hereby irrevocably designate and appoint the
               Company and its duly  authorized  officers and agents as my agent
               and  attorney-in-fact,  to act for and in my behalf  and stead to
               execute  and file any  application  or  assignment  and to do all
               other  lawfully  permitted  acts to further the  prosecution  and
               issuance to the Company of patents,  copyrights,  mask works,  or
               similar  protections thereon with the same legal force and effect
               as if executed by me.

3.   PRIOR  INVENTIONS.  I understand that all inventions,  if any,  patented or
     unpatented,  which  I made  prior  to my  employment  by the  Company,  are
     excluded  from the  scope  of this  Agreement.  To  preclude  any  possible
     uncertainty,  I have set forth in Item 1 of Exhibit A  attached  hereto and
     made a part hereof a complete list of all of my prior inventions, including
     numbers of all patents and patent applications,  and a brief description of
     unpatented  inventions which are not the property of a previous employer. I
     represent  and covenant that the list is complete and that, if no items are
     on the list, I have no such prior inventions. I agree to notify the Company
     in writing  before I make any  disclosure  or perform any work on behalf of
     the Company which appears to threaten or conflict with proprietary rights I
     claim in any  invention  or idea.  In the event of my  failure to give such
     notice,  I agree that I will make no claim against the Company with respect
     to any such inventions or ideas.

4.   CONFLICTING EMPLOYMENT OBLIGATIONS.

     (a)  TRADE SECRETS OF OTHERS.  I represent that I have not brought and will
          not  bring  with me to the  Company  or use in the  performance  of my
          responsibilities at the Company any devices,  materials,  or documents
          of a former  employer that are not generally  available to the public,
          unless I have obtained express written  authorization  from the former
          employer for their  possession  and use. The only devices,  materials,
          documents of a former employer that are not generally available to the
          public  that I will bring to the Company or use in my  employment  are
          identified on Item 2 of Exhibit A attached hereto, and as to each such
          item, I represent that I have obtained  express written  authorization
          for their  possession and use in employment  with the Company and have
          delivered a copy of such written authorization to the Company.

     (b)  CONFLICTING   CONFIDENTIALITY  AGREEMENTS.  I  agree  that  during  my
          employment  with the  Company,  I will not  breach any  obligation  of
          confidentiality that I have to former employers.  I represent that any
          performance  under the terms of this  Agreement  and as an employee of
          Company  does  not  and  will  not  breach  any  agreement  to keep in
          confidence proprietary  information acquired by me in confidence or in
          trust prior to employment by the Company. I have not entered into, and
          I agree I will not enter into, any agreement either written or oral in
          conflict herewith.

5.   GOVERNMENT CONTRACTS.  I acknowledge that the Company from time to time may
     be involved in government projects of a highly classified nature. I further
     acknowledge  that the Company  from time to time may have  agreements  with
     other  persons  or  governmental   agencies  which  impose  obligations  or
     restrictions on the Company regarding  inventions made during the course of
     work  thereunder  or  regarding  the  confidential  nature  of such work or
     information disclosed in connection  therewith.  I agree to be bound by all
     such  obligations  and  restrictions  and to take all action  necessary  to
     discharge the obligations of the Company thereunder.

6.   TERMINATION OF EMPLOYMENT. In the event of the termination of my employment
     by me or by the Company for any reason,  I will  deliver to the Company all

               Information") including without limitation,  information relating

          pay from the Company,  including  extended  periods under Section 4(f)
          herein,  and (ii)  for one  year  thereafter,  reveal  to any  person,
          association  or company  any of the  Company's  Confidential  Business
          Information, so far as such Confidential Business Information has come
          or may  come  to his  knowledge,  except  as  may be  required  in the

          association or company any of the Company's  Confidential  Proprietary
          Information,  so far as to his knowledge, except as may be required in

          or as may be required by law.

          Confidential  Information  (in particular  trade secrets and technical
          proprietary  information)  would  cause  significant  and  irreparable
          damage to the Company and would jeopardize the Company's  business and
          financial condition.

     (f)  Nothing herein shall be construed as granting to Employee any right or
          license under any copyrights,  inventions, or patents now or hereafter
          owned or  controlled  by the Company or any right to employment by the
          Company.

     (g)  In the event  Employee's  employment  is  terminated  for any  reason,
          Employee shall return all Confidential  Information in his possession,
          together with any copies, to the Company.

3.   Non-Competition.  Employee  agrees and  acknowledges  that the products and
     services to be sold and rendered by the Company are  different in character
     and are of particular  significance to the Company, and that the Company is
     in a competitive business. Due to the proprietary and specialized nature of
     the Company's business, Employee agrees to the following:

     (a)  "Non-Competition  Period" (as defined in Section 3(e))  Employee shall
          not, directly or indirectly,  induce,  influence,  combine or conspire
          with, or attempt to induce,  influence,  combine or conspire with, any
          of the officers,  employees or consultants of the Company to terminate
          their employment or relationship with the Company.

     (b)  During  his   employment   and   thereafter   during  the   applicable
          "Non-Competition  Period" (as defined in Section 3(e)), Employee shall
          not, directly or indirectly,  induce, or attempt to induce, any of the
          customers or suppliers of the Company to terminate their  relationship
          with the Company.

     (c)  During  his   employment   and   thereafter   during  the   applicable
          "Non-Competition  Period (as defined in Section 3(e)), Employee agrees
          that  he  will  not  voluntarily  or  involuntarily,  for  any  reason
          whatsoever,  directly  or  indirectly,  individually  or on  behalf of
          persons  not  now  parties  to  this  Agreement,   or  as  a  partner,
          stockholder,  director,  officer,  principal, agent, broker, licensor,
          employee,  or in any other  capacity  or  relationship,  engage in any
          business or  employment,  or aid or endeavor to assist any business or
          legal  entity,  which  is in  competition  with  the  products  and/or
          services of the Company;  provided,  however,  this Section 3(c) shall
          not be deemed to prevent  Employee from working after  termination  of
          the applicable  Non-Competition Period in any areas or division within
          the  applicable  industry.  The ownership by Employee of not more than
          five percent (5%) of shares of stock of any corporation having a class
          or equity securities actively traded on a national securities exchange
          or NASDAQ  shall not be  deemed,  in and of itself,  to  violate  this
          Section 3(c ) .

     (d)  Employee  agrees  not to do or say  anything  that  reasonably  may be
          expected to have the effect of disparaging  the Company or diminishing
          or  impairing  the  goodwill  and  reputation  of the  Company and the
          services it provides.  Likewise,  the Company  agrees not to do or say
          anything  that  reasonably  may be  expected  to have  the  effect  of
          disparaging the Employee or diminishing or impairing the reputation of
          the Employee.

     (e)  If, in any judicial proceedings a court shall refuse to enforce any of
          the other  separate  covenants  set forth in this Section 3, then such
          unenforceable  covenant  shall be  amended  to relate  to such  lesser
          period or  geographical  areas as shall be  enforceable  or, if deemed
          appropriate by such court, deemed eliminated from these provisions for
          the purpose of those proceedings to the extent necessary to permit the
          remaining separate covenants to be enforced.

     (f)  Under the terms of the Employment  Agreement,  Employee is entitled to
          receive severance pay in the event his employment is terminated by the
          Company  without  due cause.  In the event  Employee's  employment  is
          terminated for any reason whatsoever,

          (i)  during  the first  year of his  employment,  then the  applicable
               Non-Competition  Period  for  Section  3(a),  (b) and (c) will be
               eighteen (18) months; or

          (ii) during the second  year of his  employment,  then the  applicable
               Non-Competition  Period  for  Section  3(a),  (b) and (c) will be
               twelve (12) months; or

          (iii)during  the third  year of his  employment,  then the  applicable
               Non-Competition  Period for Section 3(a), (b) and (c) will be six
               (6) months; or

          (iv) by  expiration  of the Term or  otherwise,  at any time after the
               third   anniversary  of  his  employment,   then  the  applicable
               Non-Competition  Period for  Sections  3(a),  (b) and (c) will be
               three (3) months.

     (g)  Notwithstanding the foregoing,  the Company may, at its option,  elect
          to extend the applicable  Non-Competition  Period by up to twelve (12)
          additional  months by payment to Employee of additional  severance pay
          equal  to his  salary  in  effect  at the date of  termination  of his
          employment  for such time period.  Payments will be made in accordance
          with the  Company's  normal  pay  periods  for as long as the  Company
          elects to so extend the Non-Competition Period. Employee hereby agrees
          to accept such  payments as  compensation  for such  extension  of the
          applicable Non-Competition Period.

     (h)  Company and Employee hereby acknowledge that:

          (i)  Company's market for its products is unlimited geographically and
               the foregoing  noncompetition and  non-solicitation  requirements
               shall be applied on a worldwide basis;

          (ii) the duration and geographical limitations imposed with respect to
               said   noncompetition  and   non-solicitation   requirements  are
               reasonable;

          (iii)the restrictions stated hereinabove are reasonably  necessary for
               the protection of Company's legitimate proprietary interests.

     (i)  Employee   represents   and  warrants  that  his/her   experience  and
          capabilities are such that the restrictive  covenants set forth herein
          will not prevent  him/her from  earning  his/her  livelihood  and that
          Employee  will  be  fully  able to earn  an  adequate  livelihood  for
          himself/herself  and his/her  dependents if any such provisions should
          be specifically enforced against Employee.

     (j)  The non-competition and non-solicitation  obligations contained herein
          shall be extended by the length of time during  which  Employee  shall
          have been in breach of any said  provisions  and  during  any time the
          Company is required to seek compliance by judicial proceeding.

4.   Specific  Remedies.  In addition  to any other  remedy  provided  herein or
     contemplated under law, and not as liquidated damages, in the even Employee
     breaches  any  material  covenant  of  this  Agreement,  such  breach  will

     Employment  Agreement  and the  Company  shall have the right,  but not the
     obligation,   to  purchase  from  Employee  and  Employee  shall  have  the
     obligation  to sell to the Company any or all of the shares of Common Stock

     shares.  Such right shall be exercised by written notice to Employee within
     sixty  (60)  days  of  establishment  by  consent,   judicial  decision  or
     arbitration  that  Employee so breached this  Agreement.  Any of Employee's
     permitted transferees will be obligated to sell to the Company Common Stock
     shares of the Company held by them in the event the Company  exercises this
     right to purchase.

     this Agreement inoperative, unenforceable or invalid.

13.  Assignability.  Employee  may not assign  any of his rights or  obligations

     provision  or to exercise  any right,  power or remedy  hereunder,  and any

                                    EXHIBIT E
                     CONFIDENTIAL NATURE OF COMPANY AFFAIRS


PURPOSE:

It is the policy of  Exigent  International  Inc.  (Exigent)  that the  internal
business affairs of the organization,  particularly confidential information and
trade secrets,  represent proprietary assets that each employee has a continuing
obligation to protect.

POLICY:

     1.   CONFIDENTIAL INFORMATION. Information designated as confidential is to
          be discussed with no one outside the  organization  and only discussed
          within  the  organization  on a "need to  know"  basis.  In  addition,
          employees have a  responsibility  to avoid  unnecessary  disclosure of
          nonconfidential internal information about Exigent, its customers, and
          its suppliers.  This  responsibility  is not intended to impede normal
          business  communications and  relationships,  but is intended to alert
          employees to their obligations to use discretion to safeguard internal
          Exigent affairs.

     2.   VIOLATION OF UNAUTHORIZED ACCESS.  Employees authorized to have access
          to confidential  information must treat the information as proprietary
          Exigent property for which they are personally responsible.  Employees
          are prohibited from attempting to obtain confidential  information for
          which they have not received  authorization.  Employees violating this
          policy will be subject to discipline,  up to and including termination
          and may be subject to legal action.

     3.   MEDIA/INQUIRIES.  All media inquiries and other inquiries of a general
          nature  should be referred to the  President or CEO.  Also,  all press
          releases, publications, speeches, and other official declarations must
          be approved in advance by the President, Inquiries seeking information
          concerning  current  or former  employees  should be  referred  to the
          Personnel Department.

     4.   DISCUSSIONS  WITH  COMPETING  COMPANIES  AND EXIGENT  CONFIDENTIALITY.
          Employees  are  not  to  discuss  with  the  officers,  directors,  or
          employees  of  competing  companies  any topics  which  might give the
          impression of an illegal  agreement in restraint of trade. Such topics
          include pricing agreements, customer allocation, and division of sales
          territories.

     5.   MATERIAL INSIDE INFORMATION.  Employees are prohibited from disclosing
          "material inside"  information,  that could affect the market value of
          Exigent's  financial  securities,  to anyone outside the  organization
          until  such  information  has been  made  available  to the  public by
          management.  Employees are also prohibited from using such information
          for their own personal profit.

I, B. R. SMEDLEY, hereby acknowledge I have read and fully understand the above
         (Print Name)
policy and agree to comply with all terms,  conditions  and/or  requirements  as
stated.

                 twelve  months of the Term ("Third  Year"),  an amount equal to

                 periods  for  Employee  beginning  one  pay  period  after  the
                 effective date of termination; and

           (iv)  If Employee is still  employed by Company after the Third Year,
                 and  (in  the  absence  of  any  superseding  arrangement  with
                 Company,  whether  pursuant  to  renewal of this  Agreement  or
                 otherwise) is so terminated  without due cause, an amount equal

                 of Employee as of the effective date of termination, payable in
                 equal  installments  in accordance  with  Company's  normal pay
                 periods  for  Employee  beginning  one  pay  period  after  the
                 effective date of termination.


     (d)  In the  event  of  termination  by the  Company  pursuant  to  Section
          8(a)(iv) (i.e. without due cause),  Employee shall also be entitled to
          receive,  at his option and upon his written  request,  group  medical
          insurance as described in Section  3(d)(ii) during the period Employee
          is entitled  to receive  severance  pay under  Section  8(d) plus,  if
          applicable,    any    additional    extension   of   the    applicable
          "Non-Competition   Period"  (as  defined  in  the  Non-Disclosure  and
          Non-Competition   Agreement,   pursuant   to  Section   3(g)  of  such
          agreement).

     (e)  In the event of termination  upon  Employee's  disability  pursuant to
          Section 8(a)(ii),  the Company agrees to continue  Employee's  regular
          salary  payments  from the date of  termination  through  the date the
          insurance company commences long term disability insurance payments or
          denies coverage.  In the event long term disability coverage is denied
          due to admitted or proven fraud on behalf of the Employee, the Company
          will have no severance payment obligations to Employee. If coverage is
          denied for any other reason, Employee's termination will be treated as
          termination without due cause under Section 8(a)(iv) and Employee will
          be entitled to  severance  pay under  Section  8(c)  provided any such
          regular salary payments made by Company to Employee under this Section
          8(e) will be credited against Company's severance payment obligations.

     (f)  Notwithstanding  anything to the contrary set forth in this Agreement,
          in the event that Employee  dies during the Term of this  Agreement or
          any extension thereof, this Agreement shall terminate upon the date of
          such death,  provided that in the event of Employee's death during the
          Term of this  Agreement  or any  extension  thereof the Company  shall
          continue  to pay  Employee's  salary for a period of ninety  (90) days
          following  the date of death to the executor or  administrator  of the
          Employee's estate,  except in no event shall the Company be liable for
          the  payment of any such  death  benefit  which  exceeds  the  maximum
          severance payment obligations pursuant to Section 8(e) above.

     as may be  proper.  Employee  hereby  submits  to the  jurisdiction  of the
     preceding courts for the purposes of any actions or proceedings  instituted
     by the  Company to obtain  such  injunctive  relief,  and  agrees  that the
     process may be served on the Employee by registered mail,  addressed to the
     last  address  of the  Employee  known  to the  Company,  or in any  manner
     authorized by law.

15.  SEVERABILITY.  If  for  any  reason  whatsoever,  any  one or  more  of the
     provisions  of this  Agreement  shall be held or deemed to be  inoperative,
     unenforceable or invalid as applied to any particular case or in all cases,
     such  circumstances  shall not have the effect of rendering  such provision
     invalid in any other case or of rendering  any of the other  provisions  of
     this Agreement inoperative, unenforceable or invalid.

16.  ASSIGNABILITY.  By reason of the special and unique  nature of the services
     hereunder,  it is agreed that neither party hereto may assign any interest,
     rights  or duties  which it or he may have in this  Agreement  without  the
     prior  written  consent of the other  party,  except  that upon any merger,
     liquidation,  or  sale of all or  substantially  all of the  assets  of the
     Company to another  corporation,  this Agreement shall inure to the benefit
     of and be  binding  upon the  Employee  and the  purchasing,  surviving  or
     resulting  company or corporation in the same manner and to the same extent
     as though such company or corporation were the Company.

17.  WAIVERS.  The  failure  or delay  of the  Company  at any  time to  require
     performance  by the employee of any  provision of this  Agreement,  even if
     know,  shall not affect the right of the Company to require  performance of
     that provision or to exercise any right, power or remedy hereunder, and any
     waiver by the  Company of any  breach of any  provision  of this  Agreement
     should not be construed as a waiver of any continuing or succeeding  breach
     of such  provision,  a waiver of the provision  itself,  or a waiver of any
     right,  power or remedy  under  this  Agreement.  No notice to or demand on
     Employee in any case  shall,  of itself,  entitle  Employee to any other or
     further notice or demand in similar or other circumstances.

18.  INDEMNIFICATION. Company agrees to exercise its power to indemnify Employee
     in  the  situations  provided  in  the  Company's  current  Certificate  of
     Incorporation  in its form filed with the  Secretary of State for the State
     of Delaware as of the date of this Agreement.  This  indemnification  shall
     apply even if such Certificate is later amended or deleted.

19.  COVENANTS  OF THE  ESSENCE.  The  covenants  of Employee  set forth in this
     Agreement and the other  Exhibits are the essence of this  Agreement;  they
     shall be construed as independent of any other provision in this Agreement;
     and the  existence of any claim or cause of action of the Employee  against
     the  Company,  whether  predicated  on this  Agreement  or not,  shall  not
     constitute a defense to the enforcement by the Company of these covenants.

20.  SURVIVAL.  The provisions of this Agreement will survive the termination or
     expiration  of this  Agreement  where the  intent so  indicates  they shall
     survive and all other  obligations  of the Company  and the  Employee  will
     cease on termination or expiration of this Agreement.  Notwithstanding  the
     foregoing,  the Company and the Employee will remain liable for obligations
     which accrued before termination or expiration of this Agreement (including
     the  Employee's  right to be paid or reimbursed  for services  rendered and
     expenses incurred before termination or expiration of this Agreement.)

21.  ENTIRE AGREEMENT. This Agreement,  together with the agreements in the form
     attached as Exhibits hereto and all other exhibits and attachments  hereto,
     constitutes the final written  expression of all of the agreements  between
     the parties  with  respect to the subject  matter  hereof,  supersedes  all
     correspondence, understandings, discussions and negotiations concerning the
     matters specified herein, and specifically supersedes in its entirety other
     agreements between Company and Employee.  No addition to or modification of
     any provision of this Agreement shall be binding upon any party unless made
     in writing and signed by the party to be bound.

                                   EXHIBIT A
                   INCENTIVE STOCK OPTION AGREEMENT (PLAN 1Q)


     THIS AGREEMENT  dated as of the 11th day of June,  1997, (the "Grant Date")
by and between EXIGENT  INTERNATIONAL,  INC., with its principal  office at 1225
Evans Road,  Melbourne,  Florida 32904 (the "Company"),  and Don F. Riordan, Jr.
("Optionee").

                                   WITNESSETH:

     WHEREAS,  the Company has adopted an Incentive Stock Option Plan (the "Plan
1Q") as defined in Section 422 of the  Internal  Revenue  Code of 1986 to permit
options to purchase shares of the common stock of Exigent International, Inc. to
be granted to certain key employees of the Company or its subsidiaries; and

     WHEREAS,  the  Optionee  is a key  employee  of the  Company  or one of its
subsidiaries  and the  Company  desires  him/her to remain in such  employee  by
providing  him/her  with a means to acquire or to increase  his/her  proprietary
interest in the Company's success;

     NOW,  THEREFORE,  in consideration of the promises and of the covenants and
agreement set forth, the parties hereby mutually covenant and agree as follows:

     1. Subject to the terms and  conditions  of the Plan 1Q, a copy of which is
attached hereto as Exhibit "A" and made a part hereof,  and this Agreement,  the
Company  grants to the Optionee  the option to purchase  from the Company all or
any part of an  aggregate  number of 50,000  shares  of  Exigent  International,
Inc.'s  Common  Shares   (30,000,000   authorized   shares,   par  value  $0.01)
(hereinafter such shares are referred to as the "Optioned Shares").

     2. The price to be paid for the  Optioned  Shares  shall be Two and  25/100
dollars  ($2.25) per share, or 110% of current market value whichever is higher,
of the Optioned  Shares on the Grant Date,  as  determined  in good faith by the
President of the Company who is in charge of administering the Plan 1Q. However,
if it is determined by a subsequent Internal Revenue Service audit that the fair
market value of the stock at the time the option was granted  exceeded the value
established by the President,  then the option value shall be adjusted to comply
with the Internal  Revenue  Service's  determined  fair market  value,  and such
adjusted value shall apply to any and all subsequent exercise of options.

     3.  Subject  to terms  and  conditions  of the Plan 1Q and this  Agreement,
Optioned Shares may be purchased pursuant to this Agreement at any time and from
time to time during a period of three (3) years from the date  hereof,  in whole
or in part.  All options to purchase  Optioned  Shares subject to this Agreement
must be  exercised  on or before  June 11,  2000 at which  time all  unexercised
options will expire.

     4. An option may be exercised only by written  notice,  delivered or mailed
by postpaid  registered  or certified  mail  addressed  to the  Secretary of the
Company at the corporate headquarters,  specifying the number of Optioned Shares
being  purchased  in cash or its  equivalent.  Within  five  (5)  business  days
following  the date of exercise,  payment shall be made in full or by such other
payment means as shall be mutually  agreeable.  Such  purchased  shares shall be
forthwith delivered to Optionee.

     5. (a) If the Optionee's  employment  with the Company or any subsidiary of
the  Company  is  terminated  for due  cause,  this  Agreement  shall  terminate
simultaneously therewith and Optionee shall have no further right to exercise an
option thereafter. For purposes of this paragraph, "due cause" shall be the same
as defined in the Employment Agreement.

          (b) If the  Optionee  ceases to be an  employee  of the Company or any
subsidiary  of the Company  for any reason  other than (1)  termination  for due
cause as set forth in paragraph 5(a) above, or (2) death or disability, the term
of any option  shall  expire on a date not later  than  three (3)  months  after
termination.

          (c) If the  Optionee  ceases to be an  employee  of the Company or any
subsidiary of the Company by reason of disability or death within the meaning of
Section 22(e)(3) of the Internal  Revenue Code of 1986, as amended,  the term of
any option  shall  expire on a date which is not later than  twelve  (12) months
following the date of death or disability.

     6. The options  herein  granted shall not be  transferable  by the Optionee
otherwise  than by will or the  laws of  descent  and  distribution,  and may be
exercised  during the life of the Optionee only by the  Optionee,  except as set
forth in 5( c) above.

     7. If any change is made in the shares subject to the Plan 1Q or any option
granted    thereunder    (through   merger,    consolidation,    reorganization,
recapitalization,  or change in capital structure), appropriate adjustment shall
be made by the  Company  in the  number of shares  and kind of common  stock for
which options may be or may have been granted under the Plan 1Q, to the end that
such proportional  interest shall be maintained as before the occurrence of such
an event.

     8. (a) Optionee  acknowledges and understands that the Optioned Shares have
not been  registered  with the  Securities  and  Exchange  Commission  under the
Securities  Act of  1933,  as  amended,  in  reliance  upon the  exemption  from
registration  provided in Regulation D of the Act, nor with any state securities
regulatory  authority  in  reliance  upon  particular  statutory   transactional
exemptions.  As such, the shares  purchased under this Agreement,  if exercised,
cannot  be  sold  subsequently  or  otherwise   transferred  without  prior  (1)
registration  under the Act and under  applicable state law or (2) receipt of an
opinion of counsel for the issuer to the effect that such proposed sale or other
transfer does not affect the exempt status of the original  issuance and sale of
these  shares  and is in  compliance  with  all  applicable  state  and  federal
securities laws.

          (b)  That  Optionee  will be  acquiring  the  stock  for  his/her  own
investment  and personal  interest in the Company and not for the account of any
other person, with no intention on his/her part of affecting a redistribution of
such stock or any part thereof.

          (c ) That  Optionee  has asked  questions  and received all answers to
information he/she considers pertinent to form a knowledgeable opinion about his
investment.

          (d) That the Optionee  understands and acknowledges  that he/she shall
not be deemed for any purpose to be a shareholder of the Company with respect to
any of the Optioned Shares, except to the extent that the options herein granted
shall have been  exercised  with respect  thereto and a stock  certified  issued
therefor.

          (e) That the existence of the options  herein granted shall not affect
in any  way the  right  or  power  of  Exigent  International,  Inc.  to make or
authorize any or all adjustments,  recapitalizations,  reorganizations, or other
changes in Exigent  International  Inc.'s capital structure or its business,  or
any merger or  consolidation of the Company or Exigent  International,  Inc., or
any issue of bonds, debentures,  preferred or prior preference stock ahead of or
affecting  the  common  shares of  Exigent  International,  Inc.  or the  rights
thereof,  or dissolution or liquidation of Exigent  International,  Inc., or any
sale or  transfer  of all or any part of their  assets or  business or any other
corporate act or proceeding, whether of a similar character or otherwise.

          (f)  That as a  condition  of the  granting  of the  option(s)  herein
granted,  the  Optionee  agrees,  for  himself/herself,   and  his/her  Personal
Representative,  that any dispute or disagreements which may arise under or as a
result of or pursuant to this Agreement  shall be determined by the President in
his sole discretion,  and that any  interpretation by the President of the terms
of this Agreement shall be final, binding and conclusive.

     9. This Agreement shall not confer upon the Optionee any right with respect
to  continuance  of employment by the Company or its related  corporations,  nor
shall it  interfere  in any way with the  right of the  Optionee's  employer  to
terminate the Optionee's employment at any time.

     10. As used in this Agreement, the masculine, feminine or neuter gender and
the singular or plural number shall be deemed to include the others whenever the
context so indicates or requires.

     11.This  Agreement  shall be governed  and  interpreted  by the laws of the
State of Florida.

     12. This Agreement and any exhibit hereto  constitutes the entire agreement
between the parties with respect to the subject matter hereof,  and no change or
modification  shall be valid  unless  made in  writing  and  signed by the party
against whom such change or modification is sought to be enforced.

                                    Exhibit C
                Proprietary Information and Inventions Agreement


In consideration and as a condition of my employment or continued  employment by
Exigent  International Inc. and/or by companies which it owns,  controls,  or is
affiliated with, or their successors in business (the "Company"), I hereby agree
with the Company as follows:

1.   Proprietary  Information.  I  understand  that during my  employment  I may
     produce,  obtain,  make known, or learn about certain information which has
     commercial  value in the business in which the Company is engaged and which
     is treated by the Company as  confidential.  This information may have been
     created,  discovered,  or developed by the Company or otherwise received by
     the  Company  from  third  parties  subject  to  a  duty  to  maintain  the
     confidentiality  of such  information.  All such information is hereinafter
     called "Proprietary Information."

     (a)  Proprietary  Information  Defined.  By way of  illustration,  but  not
          limitation,  "Proprietary  Information" includes trade secrets, ideas,
          processes,  formulas,  source codes,  data,  programs,  other original
          works   of   authorship,    know-how,    improvements,    discoveries,
          developments,   designs,  inventions,   techniques,  marketing  plans,
          strategies, forecasts, new products, unpublished financial statements,
          budgets,  projections,  licenses,  prices,  costs,  and  customers and
          supplier lists.

     (b)  Assignment  and Protection of  Proprietary  Information.  I understand
          that all  Proprietary  Information  shall be the sole  property of the
          Company and its assigns (or, in some cases, its clients, suppliers, or
          customers),  and the Company  and its  assigns (or in some cases,  its
          clients,  suppliers,  or  customers)  shall be the  sole  owner of all
          patents,  copyrights,  and other  rights in  connection  therewith.  I
          hereby  assign to the Company any rights I may have or acquire in such
          Proprietary  Information.  At all times,  both during my employment by
          the  Company  and after  its  termination,  I will  keep in  strictest
          confidence and trust all Proprietary Information,  and I will not use,
          reproduce, or disclose any Proprietary Information without the written
          consent of the  Company,  except as may be  necessary  in the ordinary
          course of performing my duties as an employee of the Company.

     (c)  Maintenance  of Records.  I agree to keep and  maintain  adequate  and
          current records of all proprietary information developed by me (in the
          form of  notes,  sketches,  drawings  and as may be  specified  by the
          Company)  which  records  shall be  available  to and  remain the sole
          property of the Company at all times.

2.   Inventions During and Immediately After My Term of Employment. I understand
     that during my employment or following my employment,  I may make, conceive
     of, or reduce  to  practice  various  discoveries,  developments,  designs,
     improvements,  inventions, formulas, processes, techniques, programs, other
     works of authorship,  know-how, and data (all of which shall be referred to
     as "inventions"  throughout  this  Agreement,  whether or not patentable or
     registrable under copyright, mask work, or similar statutes).

     (a)  Assignment of Inventions.  I hereby assign and transfer to the Company
          my entire right,  title, and interest in and to all inventions made or
          conceived  or reduced to practice by me,  either alone or jointly with
          others,  during the period of my employment  with the Company,  except
          for those  inventions  which I have developed  entirely on my own time
          without using the Company's equipment,  supplies, facilities, or trade
          secret information  excluding those inventions that either: (1) relate
          at the time of conception or reduction to practice of the invention to
          the  business,  or  actual or  demonstrably  anticipated  research  or
          development  of the Company;  or (2) result from any work performed by
          me  for  the  Company.  I  acknowledge  that  all  original  works  of
          authorship which are made by me (solely or jointly with others) within
          the scope of my employment and which are  protectable by copyright are
          "works  made for hire," as that term is defined in the U.S.  Copyright
          Act as in effect as of this date. I will,  at the  Company's  request,
          promptly execute a written  assignment of title to the Company for any
          such invention and I will preserve any such invention as  confidential
          information of the Company.

          Notwithstanding  the foregoing,  I also hereby assign and transfer to,
          or as directed  by, the Company all my right,  title,  and interest in
          and to any and all  inventions,  full title to which is required to be
          in the United States by a contract  between the Company and the United
          States or any of its agencies.

     (b)  Maintenance  of Records.  I agree to keep and  maintain  adequate  and
          current  records of all  inventions  made by me (in the form of notes,
          sketches,  drawings  and as may be  specified  by the  Company)  which
          records  shall be  available  to and remain the sole  property  of the
          Company at all times.

     (c)  Disclosure of Inventions.  I will promptly  disclose in writing to the
          Company all inventions made or conceived or reduced to practice by me,
          either  alone  or  jointly  with  others,  during  the  period  of  my
          employment, and for six months after termination of my employment with
          the Company.

     (d)  Execution of Documents. I further agree as to all inventions to assist
          the  Company in every  proper way (but at the  Company's  expense)  to
          obtain and from time to time enforce patents,  copyrights, mask works,
          and other rights and protections relating to inventions in any and all
          countries,  and to that end I will  execute all  documents  for use in
          applying for and obtaining such patents,  copyrights,  mask works, and
          other  rights  and  protections  on and  enforcing  inventions  as the
          Company  may  desire,  together  with any  assignments  thereof to the
          Company  or  persons  designated  by it. My  obligation  to assist the
          Company in obtaining and enforcing  patents,  copyrights,  mask works,
          and other rights and protections relating to inventions in any and all
          countries shall continue beyond the termination of my employment,  but
          the  Company  shall  compensate  me at a  reasonable  rate  after such
          termination for time actually spent by me at the Company's  request on
          such assistance.  In the event the Company is unable, after reasonable
          effort,  to secure my signature on any document or documents needed to
          obtain or enforce any patent,  copyright, mask work, or other right or
          protection relating to any inventions,  whether because of my physical
          or mental  incapacity  or for any other  reason  whatsoever,  I hereby
          irrevocably  designate and appoint the Company and its duly authorized
          officers and agents as my agent and  attorney-in-fact,  to act for and
          in my  behalf  and  stead  to  execute  and file  any  application  or
          assignment and to do all other lawfully  permitted acts to further the
          prosecution and issuance to the Company of patents,  copyrights,  mask
          works,  or similar  protections  thereon with the same legal force and
          effect as if executed by me.

3.   Prior  Inventions.  I understand that all inventions,  if any,  patented or
     unpatented,  which  I made  prior  to my  employment  by the  Company,  are
     excluded  from the  scope  of this  Agreement.  To  preclude  any  possible
     uncertainty,  I have set forth in Item 1 of Exhibit A  attached  hereto and
     made a part hereof a complete list of all of my prior inventions, including
     numbers of all patents and patent applications,  and a brief description of
     unpatented  inventions which are not the property of a previous employer. I
     represent  and covenant that the list is complete and that, if no items are
     on the list, I have no such prior inventions. I agree to notify the Company
     in writing  before I make any  disclosure  or perform any work on behalf of
     the Company which appears to threaten or conflict with proprietary rights I
     claim in any  invention  or idea.  In the event of my  failure to give such
     notice,  I agree that I will make no claim against the Company with respect
     to any such inventions or ideas.

4.   Conflicting Employment Obligations.

     (a)  Trade Secrets of Others.  I represent that I have not brought and will
          not  bring  with me to the  Company  or use in the  performance  of my
          responsibilities at the Company any devices,  materials,  or documents
          of a former  employer that are not generally  available to the public,
          unless I have obtained express written  authorization  from the former
          employer for their  possession  and use. The only devices,  materials,
          documents of a former employer that are not generally available to the
          public  that I will bring to the Company or use in my  employment  are
          identified on Item 2 of Exhibit A attached hereto, and as to each such
          item, I represent that I have obtained  express written  authorization
          for their  possession and use in employment  with the Company and have
          delivered a copy of such written authorization to the Company.

     (b)  Conflicting   Confidentiality  Agreements.  I  agree  that  during  my
          employment  with the  Company,  I will not  breach any  obligation  of
          confidentiality that I have to former employers.  I represent that any
          performance  under the terms of this  Agreement  and as an employee of
          Company  does  not  and  will  not  breach  any  agreement  to keep in
          confidence proprietary  information acquired by me in confidence or in
          trust prior to employment by the Company. I have not entered into, and
          I agree I will not enter into, any agreement either written or oral in
          conflict herewith.

5.   Government Contracts.  I acknowledge that the Company from time to time may
     be involved in government projects of a highly classified nature. I further
     acknowledge  that the Company  from time to time may have  agreements  with
     other  persons  or  governmental   agencies  which  impose  obligations  or
     restrictions on the Company regarding  inventions made during the course of
     work  thereunder  or  regarding  the  confidential  nature  of such work or
     information disclosed in connection  therewith.  I agree to be bound by all
     such  obligations  and  restrictions  and to take all action  necessary  to
     discharge the obligations of the Company thereunder.

6.   Termination of Employment. In the event of the termination of my employment
     by me or by the Company for any reason,  I will  deliver to the Company all
     documents,  notes, drawings,  specifications,  programs, data, devices, and
     other materials of any nature  pertaining to my work with the Company and I
     will  neither  take  with  me  nor  recreate  any  of  the  foregoing,  any
     reproduction of any of the foregoing,  or any Proprietary  Information that
     is embodied in a tangible medium of expression.

7.   Modification.  This  Agreement  may  not be  changed,  modified,  released,
     discharged, abandoned, or otherwise amended, in whole or part, except by an
     instrument in writing,  signed by myself and the Company.  I agree that any
     subsequent change or changes in my duties,  salary,  or compensation  shall
     not affect the validity or scope of this Agreement.

8.   Entire  Agreement.  I acknowledge  receipt of this Agreement and agree that
     with respect to the subject  matter hereof it is my entire  agreement  with
     the  Company,  superseding  any  previous  oral or written  communications,
     representations,  understandings,  or  agreements  with the  Company or any
     officer or representative.

9.   Severability.  In the  event  that  any  paragraph  or  provision  of  this
     Agreement shall be held to be illegal or  unenforceable,  such paragraph or
     provision  shall be severed from this  Agreement  and the entire  Agreement
     shall not fail on account thereof, but shall otherwise remain in full force
     and effect.

10.  Successor  and  Assigns.  This  Agreement  shall be binding  upon my heirs,
     executors,  administrators,  or other legal  representatives and is for the
     benefit of the Company, its successors, and assigns.

11.  Governing  Law.  This  Agreement  shall be  governed  by and  construed  in
     accordance with the laws of the State of Delaware.

12.  Counterparts.  This  Agreement may be signed in two  counterparts,  each of
     which  shall  be  deemed  an  original  and both of  which  shall  together
     constitute one agreement.

13.  I agree  that  the  Company  may make  known to  others  either  during  or
     subsequent  to my  employment  the  existence  of  this  Agreement  and the
     provisions of all or any part thereof.

IN WITNESS  WHEREOF,  THIS  AGREEMENT  has been  executed as of this 11th day of
June, 1997 and is effective from February 7, 1997.

               Confidential  Business  Information  has  come or may come to his
               knowledge,  except as may be required in the  ordinary  course of
               performing  his duties as an officer of the  Company or as may be
               in the public  domain  through no fault of  Employee or as may be
               required by law.

               of the Confidential  Information (in particular trade secrets and
               technical  proprietary  information)  would cause significant and

               employment by the Company.

          and services to be sold and  rendered by the Company are  different in
          character and are of particular  significance to the Company, and that
          the Company is in a competitive  business.  Due to the proprietary and
          specialized nature of the Company's  business,  Employee agrees to the
          following:

          (a)  During  his  employment  and  thereafter  during  the  applicable
               "Non-Competition  Period" (as defined in Section  3(e))  Employee
               shall not, directly or indirectly,  induce, influence, combine or
               conspire  with,  or  attempt  to  induce,  influence,  combine or
               conspire with,  any of the officers,  employees or consultants of
               the Company to terminate their  employment or  relationship  with
               the Company.

          (b)  During  his  employment  and  thereafter  during  the  applicable
               "Non-Competition  Period" (as defined in Section 3(e)),  Employee

               any of the  customers  or  suppliers  of the Company to terminate
               their relationship with the Company.

          (c)  During  his  employment  and  thereafter  during  the  applicable
               "Non-Competition  Period (as defined in Section  3(e)),  Employee
               agrees that he will not  voluntarily  or  involuntarily,  for any
               reason  whatsoever,  directly or indirectly,  individually  or on
               behalf of  persons  not now  parties to this  Agreement,  or as a
               partner,   stockholder,   director,  officer,  principal,  agent,
               broker,   licensor,   employee,  or  in  any  other  capacity  or
               relationship,  engage in any  business or  employment,  or aid or
               endeavor  to assist any  business  or legal  entity,  which is in
               competition  with the  products  and/or  services of the Company;
               provided,  however,  this  Section  3(c)  shall  not be deemed to
               prevent Employee from working after termination of the applicable
               Non-Competition  Period  in any  areas  or  division  within  the
               applicable  industry.  The ownership by Employee of not more than
               five percent (5%) of shares of stock of any corporation  having a
               class  or  equity  securities   actively  traded  on  a  national
               securities  exchange  or NASDAQ  shall not be  deemed,  in and of
               itself, to violate this Section 3(c ) .

          (d)  Employee  agrees not to do or say anything that reasonably may be
               expected  to have  the  effect  of  disparaging  the  Company  or
               diminishing  or  impairing  the goodwill  and  reputation  of the
               Company  and the  services  it  provides.  Likewise,  the Company
               agrees not to do or say anything that  reasonably may be expected
               to have the effect of disparaging  the Employee or diminishing or
               impairing the reputation of the Employee.

          (e)  If, in any judicial  proceedings  a court shall refuse to enforce
               any of the other separate  covenants set forth in this Section 3,
               then such  unenforceable  covenant  shall be amended to relate to
               such lesser period or geographical  areas as shall be enforceable
               or, if deemed  appropriate by such court,  deemed eliminated from
               these  provisions  for the  purpose of those  proceedings  to the
               extent necessary to permit the remaining separate covenants to be
               enforced.

          (f)  Under the terms of the Employment Agreement, Employee is entitled
               to  receive   severance  pay  in  the  event  his  employment  is
               terminated  by the  Company  without  due  cause.  In  the  event
               Employee's employment is terminated for any reason whatsoever,

               (i)  during the first year of his employment, then the applicable
                    Non-Competition Period for Section 3(a), (b) and (c) will be
                    eighteen (18) months; or

               (ii) during  the  second  year  of  his   employment,   then  the
                    applicable  Non-Competition Period for Section 3(a), (b) and
                    (c) will be twelve (12) months; or

               (iii)during   the  third  year  of  his   employment,   then  the
                    applicable  Non-Competition Period for Section 3(a), (b) and
                    (c) will be six (6) months; or

               (iv) by expiration  of the Term or  otherwise,  at any time after
                    the third anniversary of his employment, then the applicable
                    Non-Competition  Period for Sections  3(a), (b) and (c) will
                    be three (3) months.

          (g)  Notwithstanding  the  foregoing,  the Company may, at its option,
               elect to extend the  applicable  Non-Competition  Period by up to
               twelve  (12)   additional   months  by  payment  to  Employee  of
               additional  severance  pay  equal to his  salary in effect at the
               date of  termination  of his  employment  for such  time  period.
               Payments will be made in accordance with the Company's normal pay
               periods  for as long  as the  Company  elects  to so  extend  the
               Non-Competition  Period.  Employee  hereby  agrees to accept such
               payments as  compensation  for such  extension of the  applicable
               Non-Competition Period.

          (h)  Company and Employee hereby acknowledge that:

               (i)  Company's    market   for   its    products   is   unlimited
                    geographically   and  the   foregoing   noncompetition   and
                    non-solicitation   requirements   shall  be   applied  on  a
                    worldwide basis;

               (ii) the  duration  and  geographical  limitations  imposed  with
                    respect   to  said   noncompetition   and   non-solicitation
                    requirements are reasonable;

               (iii)the   restrictions   stated   hereinabove   are   reasonably
                    necessary  for  the   protection  of  Company's   legitimate
                    proprietary interests.

          (i)  Employee  represents  and warrants  that his/her  experience  and
               capabilities  are such that the  restrictive  covenants set forth
               herein will not prevent him/her from earning  his/her  livelihood
               and  that  Employee  will be  fully  able  to  earn  an  adequate
               livelihood for himself/herself and his/her dependents if any such
               provisions should be specifically enforced against Employee.

          (j)  The non-competition and  non-solicitation  obligations  contained
               herein  shall be  extended  by the  length of time  during  which

     contemplated under law, and not as liquidated damages, in the even Employee

     obligation,   to  purchase  from  Employee  and  Employee  shall  have  the

<PAGE>
                                                                      Exhibit E

                     CONFIDENTIAL NATURE OF COMPANY AFFAIRS

PURPOSE:

It is the policy of  Exigent  International  Inc.  (Exigent)  that the  internal
business affairs of the organization,  particularly confidential information and
trade secrets,  represent proprietary assets that each employee has a continuing
obligation to protect.

POLICY:

1.   CONFIDENTIAL  INFORMATION.  Information designated as confidential is to be
     discussed with no one outside the  organization  and only discussed  within
     the  organization on a "need to know" basis. In addition,  employees have a
     responsibility to avoid unnecessary disclosure of nonconfidential  internal
     information  about  Exigent,  its  customers,   and  its  suppliers.   This
     responsibility is not intended to impede normal business communications and
     relationships,  but is intended to alert employees to their  obligations to
     use discretion to safeguard internal Exigent affairs.

2.   VIOLATION OF UNAUTHORIZED  ACCESS.  Employees  authorized to have access to
     confidential  information must treat the information as proprietary Exigent
     property  for  which  they  are  personally   responsible.   Employees  are
     prohibited  from  attempting to obtain  confidential  information for which
     they have not received authorization.  Employees violating this policy will

     customer allocation, and division of sales territories.

5.   MATERIAL  INSIDE  INFORMATION.  Employees are  prohibited  from  disclosing
     "material  inside"  information,  that could  affect  the  market  value of

     Employees are also  prohibited  from using such  information  for their own
     personal profit.
