information and Consolidated Financial Statements,  including the Notes thereto,
appearing  elsewhere in this  Prospectus,  including the  information  set forth
under "Risk Factors." Each prospective investor is urged to read this Prospectus
in its  entirety.  Certain  statements  contained in this  Prospectus  regarding
matters  that are not  historical  facts such as  statement  regarding  expected
future  sales cycles for the  Company's  products  and  expected  revenues  from
licensing  arrangements are forward-looking  statements (as such term is defined
in the  Securities  Act).  Since  forward-looking  statements  include risks and
uncertainties,  actual  results may differ  materially  from those  expressed or
implied by such  statements.  Factors that could cause actual  results to differ
materially  include,  but are not limited to, those discussed herein under "Risk
Factors,"  "Management's  Discussion  and  Analysis of Financial  Condition  and
Results of Operations" and  "Business," as well as those discussed  elsewhere in
this Prospectus.

         Unless otherwise  indicated,  all share  information in this Prospectus
gives  effect  to:  (i) a  two-for-one  stock  split in the form of a 100% share
distribution on the Company's  Common Stock effected in August 1996; (ii) a one-
for-six  Common Stock dividend paid in May 1996; and (iii) the conversion of all
outstanding  shares of Preferred Stock and all accrued unpaid dividends  thereon
into  199,883  shares of Common  Stock  effected  in 1996.  Except as  otherwise
specified,  the  information in this Prospectus does not give effect to exercise
of the  Underwriters'  over-allotment  option or the  Representatives'  Purchase
Option.  Unless  the  context  otherwise  requires,  references  herein  to  the
"Company" or "Infodata" refer to Infodata Systems Inc. and its subsidiaries.

                                   THE COMPANY

         Infodata provides  electronic  document management software and systems
to corporate and government workgroups, departments and enterprises.  Infodata's
newest  product,  Virtual File  Cabinet(TM)  ("VFC(TM)"),  has been  designed to
address what  DataPrOpinion has called one of the biggest problems facing global
organizations:  the fact that  their  critical  assets  are often  contained  in
documents   stored  in  disparate  and   incompatible   systems.   According  to
DataPrOpinion,   "accessing  and  sharing  that   information   among  different
departments across the enterprise has been a nightmare."

         VFC is a family of  intranet-based  software  products that,  together,
will  enable  users  to  easily  retrieve,  organize  and  share  desktop  files
irrespective of the location or type of document management system in which they
are  stored  with  virtually  no  integration  effort  and  without  the need to
replicate documents. The VFC family of products consists of the VFC Document Web
Server,  extensions  and  enablers.  The VFC Document Web Server is the heart of
VFC, and is required in order to utilize all other  components of VFC. This core
package  consists of software  installed on a server that  establishes  links to
documents,  organizes  access to stored  information  and acts as an independent
document  sharing  system.  The Company has been  shipping  the VFC Document Web
Server since the second quarter of 1997. Extensions are software components that
are installed on an individual  user's computer to add  functionality to the VFC
Document  Web Server.  In October  1997,  the Company  began  shipping its first
extension  and expects to introduce  other  extensions  in the future.  Enablers
provide  the  capability  to bridge  multiple  document  management  systems  or
repositories.  The first  enablers are expected to be available  for shipment in
the second quarter of 1998.

         The Company's  VFC  technology  has been  endorsed by leading  industry
vendors,  including Lotus Development  Corporation ("Lotus"), PC DOCS, Inc. ("PC
DOCS"), Verity, Inc. ("Verity"),  and NovaSoft Systems, Inc.  ("NovaSoft"),  and
has received numerous favorable industry trade analyst and press reviews. At the
April 1997  Association for Information  and Imaging  Management  ("AIIM") trade
show, with more than 35,000 attendees and 325 exhibitors, Imaging World Magazine
identified VFC as "#1 TO WATCH".  VFC has been sold to large  organizations with
significant document processing requirements,  such as the Department of Energy,
AT&T Corp.  ("AT&T"),  State Street Bank and Trust Company ("State Street Bank")
and the U.S. Army Signal Corps.

         In December 1997, the Company and Adobe Systems Incorporated ("Adobe"),
a major  software  company  with  reported  1996  revenues of greater  than $750
million,  entered  into  an  agreement  to  cross  license  and  market  certain
technologies. Adobe has a significant presence in the Internet marketplace with,
according to Adobe,  more than 20 million  downloads of its Adobe Acrobat Reader
viewing product.  Under the agreement,  the Company expects to receive more than
$700,000 in consulting  fees for  modifications  to certain of its technology so
that  it may be  incorporated  into  certain  Adobe  products.  Upon  successful
completion  of these  modifications,  the  Company  will earn a  license  fee of
$1,000,000.  Certain  components  of VFC that will be  licensed to Adobe will be
incorporated in future Adobe products. In addition,  certain Adobe products will
display  a "VFC  button"  that  will  provide  a  direct  


                                      - 3 -

<PAGE>

link to VFC or to VFC marketing information if the user does not have VFC. Adobe
will  receive  royalties  based on sales of VFC  arising  out of this  marketing
arrangement,  and will also receive  commissions for any VFC sales that it makes
directly.

         The Company's other products include Re:mark(R),  a plug-in product for
Adobe  Acrobat(TM)  software that enables users to mark up and review  documents
electronically in a workgroup setting;  Compose(R), a suite of plug-in tools for
Adobe  Acrobat  Exchange  that  automate  and  streamline  a variety of document
production tasks;  Aerial(TM), a plug-in that enables Adobe Acrobat to print any
document that needs to be magnified by  formatting  the document for printing on
multiple pages that are then pieced  together to form one page,  such as a large
spreadsheet or a CAD drawing;  Signet(TM), a security solution for Web or CD-ROM
publishers  who want to permit only  authorized  users to read their  documents;
INQUIRE(R)/Text,  a full-text  retrieval  product  used for  storing,  indexing,
retrieving and managing large collections of documents on IBM and IBM-compatible
mainframes;  and WebINQUIRE(TM),  an extension product that provides Web browser
access to  INQUIRE/Text  collections.  In addition,  the Company offers document
systems consulting services,  training and customer support for its own products
and those of other vendors,  including  Adobe,  Verity,  PC DOCS and Documentum,
Inc. ("Documentum"), for each of whom it is a value-added reseller ("VAR").

         For nearly  thirty  years,  the Company has  developed and sold its own
products  and acted as a VAR of  client/server  and  Internet/intranet  document
systems  products.  Recently,  the Company made two  acquisitions to broaden its
product and service offerings: Merex, Inc. ("Merex"),  acquired in October 1995,
and AMBIA Corporation  ("AMBIA"),  acquired in July 1997. Merex provided a staff
experienced  in Internet  and  client-server  document  technologies,  and AMBIA
provided both an experienced  technical staff and products  focusing on document
creation, collaboration, and presentation.

         The  Company  targets  both  commercial  and  government  markets.  The
Company's  products and  consulting  services are used by many major  companies,
including  Ford  Motor  Company  ("Ford"),   Allen-Bradley   Co.,  Inc.  ("Allen
Bradley"), The Boeing Company ("Boeing"),  RJR Nabisco, Inc. ("Nabisco"),  AT&T,
Chase  Manhattan Bank  ("Chase"),  State Street Bank and The Riggs National Bank
("Riggs"),  and by government  organizations,  including NASA, the Department of
Energy, the U.S. Army Signal Corps, the Government Accounting Office and various
agencies  within  the  intelligence  community.  Sales to  government  customers
represented  approximately 45% of revenues in 1996 and approximately 39% for the
first nine months of 1997;  however, no one customer accounted for more than 10%
of the Company's revenues in either period. The Company has repeat business from
a number of its customers,  and management  believes that there is a high degree
of  customer  satisfaction  with  its  products,  services  and  solutions.  The
Company's existing services,  training,  and products provide a base of business
that  complements VFC product sales.  Developing  custom solutions for customers
keeps  the   Company's   technical   professionals   abreast  of  client  needs,
facilitating  the conception and  development of new products,  such as VFC, and
the improvement of existing products.

         The Company  conducts its sales and marketing  efforts  through several
channels, including a network of VARs, its own sales force, marketing alliances,
marketing communications and training programs. The Company's VARs and its sales
force receive  direct  support from the Company's  technical  staff.  Consulting
services  leads are also provided to the Company by the vendors for whom it acts
as a VAR. The Company  believes this  diversity of sales and marketing  channels
permits it to distribute  its products and sell its services in an efficient and
effective manner, while reducing reliance on any one sales channel.

         The Company's  objectives are to establish VFC as the de facto industry
standard  for  document  access and to become a leading  provider of  electronic
document  information  management  software and  systems.  To  accomplish  these
objectives,  the Company intends to (i) maintain its  technological  leadership,
(ii)  add  strategic   relationships   (iii)  expand  its  sales  and  marketing
capabilities,   and  (iv)  pursue   acquisitions  of  businesses,   products  or
technologies that complement the Company's existing business.  As of the date of
this Prospectus, the Company has no agreement, arrangement or understanding with
respect to any acquisition.

         In 1996,  the  Company's  revenues were  $9,560,000  with net income of
$503,000.  For the first nine  months of 1997,  revenues  were  $7,033,000.  The
Company  incurred  losses of $2,579,000  for the first nine months of 1997,  due
primarily to the  continuing  investment in VFC  technology  and the expenses of
building the infrastructure to market VFC.

         The Company was  incorporated  in the State of New York in May 1968 and
reincorporated  in the State of Virginia in March 1995. The Company's  principal
offices  are located at 12150  Monument  Drive,  Fairfax,  Virginia  22033.  Its
telephone number is (703) 934-5205 and its fax number is (703) 934-7154.

                                  RISK FACTORS

         The   securities   offered  hereby  involve  a  high  degree  of  risk.
Accordingly,  in  analyzing  an  investment  in  these  securities,  prospective
investors  should carefully  consider,  along with the other matters referred to
herein,  the following  risk factors.  No investor  should  participate  in this
Offering unless such investor can afford a complete loss of his investment.

CONTINUED  LOSSES;  ACCUMULATED  AND WORKING  CAPITAL  DEFICITS;  UNCERTAINTY OF
FUTURE OPERATING RESULTS; FLUCTUATIONS IN QUARTERLY OPERATING RESULTS

         For the nine months  ended  September  30, 1997,  due  primarily to the
continuing  investment  in VFC  technology  and the  expenses  of  building  the
infrastructure to market VFC, the Company reported a net loss of $2,579,000.  In
addition,  as of September 30, 1997, the Company had an  accumulated  deficit of
$9,246,000 and a working  capital  deficit of $892,000.  The Company  expects to
continue to incur net losses through at least the end of 1998.  Future operating
results will depend upon many  factors,  including  the demand for the Company's
products,  the  effectiveness  of the  Company's  efforts to  integrate  various
products it has developed or acquired and to achieve the desired levels of sales
from such product integration,  the level of product and price competition,  the
length of the Company's sales cycle,  seasonality of individual  customer buying
patterns, the size and timing of individual transactions,  the delay or deferral
of customer  purchases and  implementations,  the budget cycles of the Company's
customers,  the timing of new product  introductions and product enhancements by
the Company and its  competitors,  the mix of sales by  products,  services  and
distribution channels,  acquisitions by competitors,  the ability of the Company
to develop and market new  products  and  control  costs,  and general  domestic
economic and political  conditions.  As a result of these factors,  revenues and
operating  results  for  any  quarter  are  subject  to  variation  and  are not
predictable  with  any  significant   degree  of  accuracy.   See  "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

CHANGE IN MIX OF PRODUCTS; DECLINE IN INQUIRE/TEXT SALES; RELIANCE ON VFC

         The Company's  historical  consolidated  financial  statements  include
results  of  operations  relating  to sales  of its  INQUIRE/Text  products  and
maintenance services related to INQUIRE/Text.  INQUIRE/Text maintenance revenues
represented 25% of the Company's  revenues in 1996 and approximately 23% for the
first nine months of 1997.  INQUIRE/Text-related revenues decreased 14% in 1996,
as compared to 1995,  and a similar  decline is expected in 1997.  Declines  are
expected  each year as the market  matures  and  customers  either  migrate  off
mainframe  platforms  or opt not to renew  maintenance  contracts.  The  Company
expects  the VFC family of products  to account  for a  substantial  part of its
future  revenues.  As a result,  factors  adversely  affecting the pricing of or
demand for VFC products, such as competition or technological change, could have
a material  adverse  effect on the  Company's  business,  operating  results and
financial   condition.   The  Company's  future   performance  will  depend,  in
significant  part,  on  the  successful  development,  introduction  and  market
acceptance  of new and  enhanced  versions of VFC  products.  The success of the
Company's VFC family of products,  the first release of which was shipped in the
second  quarter  of 1997,  will  depend  upon the  acceptance  of  intranet  and
Web-based  technologies.  As the  commercial  market  for  products  for  use on
corporate  intranets  has  only  recently  begun  to  develop,  there  can be no
assurance  that the  Company's new products or  enhancements  will meet customer
requirements or be compatible with emerging standards. There can be no assurance
that the Company will be  successful  in  developing  and  marketing VFC and its
related  products.  As a result of the  changing  mix of products  and  services
offered  by  the  Company,  the  Company's  historical   consolidated  financial
statements may not be indicative of future operating results.  See "Management's
Discussion  and  Analysis of  Financial  Condition  and Results of  Operations,"
"Business--Products  and Services,"  "--Sales and  Marketing,"  "--Research  and
Development" and "--Competition."

LENGTHY SALES AND IMPLEMENTATION CYCLES

         The  license  of the  Company's  software  products  and the use of the
Company's systems solutions  services generally require the Company to provide a
significant  level of education to prospective  customers  regarding the use and
benefits  of  the  Company's  products,  resulting  in  a  lengthy  sales  cycle
(typically between three and six


                                      - 7 -


<PAGE>

months). Additionally, the implementation by customers of the Company's products
may involve a  significant  commitment  of resources by such  customers  over an
extended  period of time.  For these and other  reasons,  the sales and customer
implementation  cycles are subject to a number of significant  delays over which
the  Company  has  little  or  no  control.   Delay  in  the  sale  or  customer
implementation  of the  Company's  products and  services  could have a material
adverse effect on the Company's  business and operations and cause the Company's
operating results to vary significantly from quarter to quarter.  Therefore, the
Company believes that its quarterly  operating results are likely to vary in the
future.  See  "Management's  Discussion and Analysis of Financial  Condition and
Results of Operations" and "Business--Sales and Marketing."

RAPID TECHNOLOGICAL CHANGE; PRODUCT OBSOLESCENCE

         The  document  management  software  market is  characterized  by rapid
technological  developments,  evolving industry  standards,  changes in customer
requirements  and frequent new product  introductions  and  enhancements,  which
often lead to product  obsolescence.  There can be no assurance that the Company
will be  successful in developing  and  marketing  enhancements  to its existing
products,  or new  products,  on a  timely  basis  or that  any new or  enhanced
products will adequately  address the changing needs of the marketplace.  If the
Company is unable to develop  and  introduce  new  products or  enhancements  to
existing products in a timely manner in response to changing market  conditions,
technological  changes or customer  requirements,  the  Company's  business  and
operating results could be adversely affected. See "Management's  Discussion and
Analysis    of    Financial    Condition    and    Results    of    Operations,"
"Business--Competition" and "--Research & Development."

COMPETITION

         The  market  for the  Company's  products  and  services  is  intensely
competitive and subject to rapid change caused by new product  introductions and
other  market  activities  of  industry  participants.   The  Company  currently
encounters  direct and indirect  competition from a number of public and private
companies  involved  in  groupware,   document  management,   and  collaboration
software,  including Xerox Corporation  ("Xerox"),  Open Text Corporation ("Open
Text"),   Net-it   Software   Corporation   ("Net-it   Software"),   Hummingbird
Communications  Ltd.  ("Hummingbird") and Fulcrum  Technologies,  Inc. ("Fulcrum
Technologies").  The  Company  is aware  that  other  companies  have  announced
products  with some features  similar to VFC. In addition,  the Company may face
competition  from new market  entrants.  Competitors  may have longer  operating
histories,   significantly  greater  financial,   marketing,  service,  support,
technical  and other  resources  and name  recognition,  and a larger  installed
customer base than the Company.  As a result,  such  competitors  may be able to
respond  more  quickly to new or emerging  technologies  and changes in customer
requirements or to devote greater  resources to the  development,  promotion and
sale of their products than the Company. See "Business--Competition."

RISKS ASSOCIATED WITH SALES CHANNELS

         The  Company's  ability to achieve  significant  revenue  growth in the
future will depend,  in large part,  upon its ability to establish  and maintain
relationships  with VARs and strategic  alliances with systems  integrators  and
computer  software and hardware  distributors,  its ability to attract qualified
sales personnel and the success of its direct sales campaigns and  telemarketing
efforts. Furthermore, the Company's ability to market its products successfully,
including  its new  products  under  development,  will depend on its ability to
adapt its sales channels to address the evolving markets for such products.  The
failure  of the  Company  to expand its VAR  network,  enter into new  strategic
alliances and recruit and train its own sales personnel,  and the failure of the
Company to adapt its  marketing  methods and sales  channels  to address  market
needs, could have a material adverse effect on the Company's business, operating
results  and  financial  condition.  In  addition,  the gross  profit  margin on
indirect  sales will be lower than gross  profit  margins on direct  sales.  See
"Business--Strategy" and "--Sales and Marketing."

         Even if the Company is  successful  in  expanding  its sales  channels,
there  can be no  assurance  that  its  sales  channels  will be  successful  in
increasing the Company's  revenue to a sufficient  extent to cover the increased
expenses associated with such expansion. Moreover, the Company's agreements with
its VARs generally are nonexclusive and may be terminated by either party at any
time without cause. The Company's VARs are not


                                      - 8 -


<PAGE>

within the control of the Company,  are not obligated to purchase  products from
the Company  and may also  represent  or refer  product  lines of the  Company's
competitors.  VARs'  sales  tend to  fluctuate  based  on  their  implementation
schedules and internal  resources,  which are beyond the control of the Company.
There can be no assurance  that VARs will continue  their current  relationships
with the  Company  or that they  will not give  higher  priority  to the sale or
referral of other  products,  which  could  include  products  of the  Company's
competitors.  A  reduction  in  sales  efforts  or  discontinuance  of  sales or
referrals of the Company's  products by its VARs could lead to reduced sales and
could materially adversely affect the Company's business,  operating results and
financial condition. See "Business--Sales and Marketing."

DEPENDENCE ON GOVERNMENT CONTRACTS; SECURITY CLEARANCES

         Sales  to  agencies  of the  United  States  Government  account  for a
significant  portion of the Company's  revenues.  The Company  believes that the
success and  development  of its business  will  continue to be dependent on its
ability  to  participate  in  government  contract  programs.  Accordingly,  the
Company's  financial   performance  may  be  directly  affected  by  changes  in
government  contracting  policies.  Among  the  factors  that  could  materially
adversely  affect the Company's  government  contracting  business are budgetary
constraints,  budget cycles,  changes in fiscal  policies or available  funding,
changes in government  programs or  requirements,  including  curtailment of the
government's  use of  technology  service  firms,  the  adoption  of new laws or
regulations, technological developments and general economic conditions.

         The Company's government contracts contain standard termination clauses
that permit the  government  to terminate  the  contracts  at any time,  without
cause, for the convenience of the government. In addition,  government contracts
require compliance with various procurement regulations.  The adoption of new or
modified  procurement  regulations could materially adversely affect the Company
or increase its costs of competing for or performing government  contracts.  Any
violation of these regulations could result in the termination of the contracts,
imposition  of  fines,   damages  and/or  debarment  from  award  of  additional
government  contracts.  The termination of the Company's government contracts or
the imposition of fines,  damages or suspension and/or debarment from bidding on
additional  government  contracts  could have a material  adverse  effect on the
Company.   Most  government  contracts  are  also  subject  to  modification  or
termination  in the event of changes in funding,  and the Company's  contractual
costs and revenue are subject to adjustment as a result of audits by the Defense
Contract  Audit  Agency  ("DCAA")  and  other  government   auditors.   Further,
government contract awards may be subject to protest by competitors.

         Many of the  Company's  government  contracts  require  the Company and
certain of its  employees to maintain  security  clearances  complying  with the
requirements of various  government  agencies.  If these clearances are lost, it
could have a material adverse effect on the Company. See "Business--Customers."

DEPENDENCE ON PROPRIETARY RIGHTS

         The  Company   relies   primarily  on  a  combination   of  copyrights,
trademarks, trade secrets, confidentiality procedures and contractual provisions
to protect its proprietary rights. For example, the Company licenses rather than
sells its software.  The licenses impose certain  restrictions on the licensees'
ability to  utilize  the  software.  In  addition,  the  Company  seeks to avoid
disclosure of its trade  secrets,  including,  but not limited to, (i) requiring
those persons with access to the Company's  proprietary  information  to execute
confidentiality  agreements with the Company and (ii) restricting  access to the
Company's  source  codes.  Trade secret and  copyright  laws afford only limited
protection.  Although  the  Company may apply for certain  design  patents,  the
Company  presently has no patents or patent  applications  pending.  Despite the
Company's efforts to protect its proprietary  rights,  unauthorized  parties may
attempt to copy the Company's products or to obtain and use information that the
Company  regards as  proprietary.  Policing  unauthorized  use of the  Company's
products is  difficult,  and while the Company  may be unable to  determine  the
extent to which piracy of its software  products exists,  software piracy can be
expected to be a  persistent  problem.  In  addition,  the laws of some  foreign
countries do not protect the Company's  proprietary rights to as great an extent
as the laws of the United  States.  There can be no assurance that the Company's
means  of  protecting  its  proprietary  rights  will be  adequate  or that  the
Company's competitors will not develop similar technology  independently.  There
can be no  assurance,  that third  parties  will not claim  infringement  by the
Company


                                      - 9 -


<PAGE>

with respect to current or future products. The Company expects software product
developers  increasingly to be subject to  infringement  claims as the number of
products  and  competitors  in the  Company's  industry  segment  grows  and the
functionality  of products in different  industry  segments  overlaps.  Any such
claims,  with or  without  merit,  could be  time-consuming,  result  in  costly
litigation,  cause product  shipment delays or require the Company to enter into
royalty or  licensing  agreements.  Such  royalty or  licensing  agreements,  if
required,  may not be  available on terms  acceptable  to the Company or at all,
which  could  have a  material  adverse  effect  upon  the  Company's  business,
operating results and financial condition.  In addition, the Company also relies
on certain software that it licenses from third parties, including software that
is  integrated  with  internally  developed  software and used in the  Company's
products to perform key  functions.  There can be no assurances  that such firms
will remain in business,  that they will continue to support  their  products or
that their  products  otherwise  will continue to be available to the Company on
commercially reasonable terms. See "Business--Proprietary Rights."

DEPENDENCE ON KEY PERSONNEL

         The Company's success depends,  in significant part, upon the continued
services  of its key  technical,  marketing,  sales  and  management  personnel,
including James Ungerleider,  its President and Chief Executive Officer, Richard
Tworek,  its Chief  Technology  Officer and Executive Vice  President,  and Razi
Mohiuddin,  its Vice  President,  and on its  ability to  continue  to  attract,
motivate and retain highly qualified employees.  The loss of key personnel could
have a material adverse effect on the Company's business,  operating results and
financial condition.  Competition for technical, marketing, sales and management
employees is intense and the process of locating  personnel with the combination
of skills and  attributes  required to execute  the  Company's  strategy  can be
difficult,  time-consuming  and  expensive.  There can be no assurance  that the
Company will be  successful  in  attracting,  assimilating  or retaining  highly
skilled technical,  management,  sales and marketing  personnel.  The failure to
attract, hire, assimilate or retain such personnel could have a material adverse
effect on the Company's business, operating results and financial condition. See
"Management."

CONCENTRATION OF STOCK OWNERSHIP

         Upon  completion of this  Offering,  the present  directors,  executive
officers and principal  shareholders  of the Company and their  affiliates  will
beneficially own approximately 33.5% of the Company's Common Stock. As a result,
these  shareholders  will be able to  exercise  significant  influence  over all
matters requiring shareholder approval,  including the election of directors and
approval of significant corporate transactions.  Such concentration of ownership
may have the  effect  of  delaying  or  preventing  a change in  control  of the
Company. See "Principal Shareholders."

PRODUCT DEFECTS

         Due to the  complexity  and  sophistication  of the Company's  software
products,  the Company's  products  from time to time contain  defects or "bugs"
that can be  difficult  to correct.  Furthermore,  as the Company  continues  to
develop and enhance its  products,  there can be no  assurance  that the Company
will be able to identify and correct defects in such a manner as will permit the
timely  introduction  of such products.  Moreover,  the Company may from time to
time discover  defects only after its systems have been used by many  customers.
There can be no assurance that, in the future,  software  defects will not cause
delays in  product  introductions  and  shipments,  result in  increased  costs,
require design modifications, or impair customer satisfaction with the Company's
products.  Any such event could have a material  adverse effect on the Company's
business, operating results and financial condition. See "Business--Research and
Development."


PRODUCT LIABILITY

         The Company's license  agreements with its customers  typically contain
provisions  designed  to limit  the  Company's  exposure  to  potential  product
liability  claims.  However,  it is possible  that the  limitation  of liability
provisions  contained in the Company's  license  agreements may not be effective
under  the  laws  of  certain  jurisdictions.   Although  the  Company  has  not
experienced any product liability claims to date, the sale and support


                                     - 10 -


<PAGE>

of products by the Company may entail the risk of such claims,  and there can be
no assurance  that the Company will not be subject to such claims in the future.
A successful  product  liability  claim brought against the Company could have a
material  adverse  effect upon the  Company's  business,  operating  results and
financial condition. See "Business--Customers."

ACQUISITIONS

         The Company may, from time to time, pursue  acquisitions of businesses,
products or technologies that complement or expand its existing business and, in
fact,  acquired Merex in 1995 and AMBIA in 1997. The Company evaluates potential
acquisition  opportunities  from time to time,  including  those  that  could be
material in size and scope.  Acquisitions  involve a number of risks,  including
the  diversion of  management's  attention  from  day-to-day  operations  to the
assimilation  of the operations and personnel of the acquired  companies and the
incorporation of acquired operations,  customer bases, products or technologies.
Such acquisitions  could also have adverse  short-term  effects on the Company's
operating results and could result in dilutive  issuances of equity  securities,
the incurrence of debt and the loss of key employees. In addition, many business
acquisitions   must  be   accounted   for  as   purchases   and,   because  most
software-related  acquisitions  involve the purchase of  significant  intangible
assets, these acquisitions typically result in substantial  amortization charges
and charges for acquired research and development  projects,  which could have a
material  adverse  effect on the Company's  operating  results.  There can be no
assurance that any such acquisitions will occur or that, if such acquisitions do
occur, the acquired  businesses,  customer bases,  products or technologies will
generate  sufficient  revenue to offset the  associated  costs or  effects.  See
"Business--Strategy."

BROAD  DISCRETION IN  ALLOCATION  OF NET PROCEEDS;  USE OF NET PROCEEDS TO REPAY
DEBT

         Approximately  $___,  or ___%  (assuming  a $_____  per share  offering
price),  of the  estimated  net proceeds of the  Offering has been  allocated to
working  capital and general  corporate  purposes.  Accordingly,  the  Company's
management will have broad discretion as to the application of these proceeds. A
portion of the proceeds  allocated to working capital may be used by the Company
to  pay  salaries,  including  salaries  of  its  executive  officers,  and  for
acquisitions.  Although the Company  currently has no agreement,  arrangement or
understanding with respect to any acquisition, should an acquisition opportunity
be  identified  by the  Company,  the Board may have the  ability to approve the
acquisition without seeking shareholder  approval.  Approximately  $1,000,000 of
the  estimated  net proceeds of the Offering has been  allocated to repayment of
institutional debt and will not be available to be used for other purposes.  See
"Use of Proceeds."

DILUTION

         The public offering price is substantially higher than the net tangible
book  value per  share of the  currently  outstanding  Common  Stock.  Investors
purchasing  shares of Common Stock in the  Offering  will  therefore  experience
immediate dilution in net tangible book value of $ ___ per share  (approximately
__%), assuming a public offering price of $______ per share. See "Dilution."

LACK OF DIVIDENDS

         The Company has never declared or paid any cash dividends on its Common
Stock and does not anticipate  paying any dividends in the  foreseeable  future.
See "Dividend Policy."

LOW TRADING VOLUME; POSSIBLE VOLATILITY OF STOCK PRICE

         For the nine months ended September 30, 1997, the average daily trading
volume of the Common  Stock was  approximately  8,892  shares.  This low trading
volume may have had a significant effect on the market price of the Common Stock
and, accordingly,  historical prices may not necessarily be indicative of market
prices in a more liquid market.  The trading price of the Company's Common Stock
is subject to  significant  fluctuations  in response to variations in quarterly
operating  results,  the gain or loss of significant  orders,  announcements  of
technological  innovations  or new  products by the Company or its  competitors,
general conditions in the software


                                     - 11 -


<PAGE>

and computer  industries and other events or factors,  including factors outside
the Company's control. In addition,  the stock market in general has experienced
extreme price and volume  fluctuations  which have affected the market price for
many companies in industries similar or related to that of the Company and which
have been  unrelated to the  operating  performance  of these  companies.  These
market  fluctuations  may  adversely  affect the market  price of the  Company's
Common Stock. See "Price Range of Common Stock."

ANTI-TAKEOVER  EFFECT  OF  CERTAIN  CHARTER,  BYLAW  AND  STATUTORY  PROVISIONS;
POSSIBLE ISSUANCE OF PREFERRED STOCK

         The Company's  Articles of Incorporation  ("Articles")  and Bylaws,  as
well as Virginia  corporate law, contain certain  provisions that could have the
effect of making it more difficult for a third party to acquire, or discouraging
a third  party  from  attempting  to  acquire,  control  of the  Company.  These
provisions could limit the price that certain  investors might be willing to pay
in the  future  for  shares of the  Company's  Common  Stock.  Certain  of these
provisions allow the Company to issue, without shareholder  approval,  preferred
stock having rights senior to those of the Common Stock. Other provisions impose
various  procedural and other requirements that could make it more difficult for
shareholders  to  effect  certain   corporate   actions.   See  "Description  of
Securities--Virginia   Anti-Takeover   Law  and   Certain   Charter   and  Bylaw
Provisions."

SHARES ELIGIBLE FOR FUTURE SALE; POTENTIAL EXERCISE OF OPTIONS AND WARRANTS

         Sales of the  Company's  Common  Stock in the public  market after this
Offering  could  adversely  affect  the  market  price  of the  Common  Stock or
outstanding warrants. See "Shares Eligible for Future Sale."

EFFECT OF OUTSTANDING OPTIONS AND WARRANTS

         As of the date of this  Prospectus,  there are  outstanding  options to
purchase  1,350,366 shares of Common Stock and outstanding  warrants to purchase
4,666 shares of Common Stock. In addition, in connection with this Offering, the
Company will issue the  Representatives'  Purchase Option.  The exercise of such
outstanding  options and warrants would dilute the  then-existing  shareholders'
percentage  ownership of the Company's stock, and any sales in the public market
of Common Stock  underlying such securities  could adversely  affect  prevailing
market prices for the Common Stock.  Moreover,  the terms upon which the Company
would be able to obtain  additional  equity capital could be adversely  affected
since the holders of such  securities can be expected to exercise them at a time
when the Company would, in all likelihood,  be able to obtain any needed capital
on terms more favorable to the Company than those  provided by such  securities.
See "Description of Securities" and "Underwriting."

POSSIBLE DELISTING OF SECURITIES FROM NASDAQ SYSTEM

         The  Company's  Common  Stock is listed on The Nasdaq  SmallCap  Market
("Nasdaq").  In August 1997,  the Company  received a notice from Nasdaq that it
was not in compliance with Nasdaq's  requirement  that listed issuers maintain a
minimum of  $1,000,000  in capital and surplus.  In November  1997,  the Company
appeared  at  a  hearing  before  a  Nasdaq  Listing   Qualifications  Panel  to
demonstrate  compliance with the minimum capital and surplus  requirement and to
request  continued  listing on Nasdaq.  The panel agreed to allow the Company to
continue to be listed if (i) on or before February 16, 1998, the Company makes a
public  filing with the  Commission  and Nasdaq  evidencing  the closing of this
Offering and a minimum of $5,500,000 in net tangible assets and (ii) the Company
is able to  evidence  compliance  with  Nasdaq's  new  standards  for  continued
listing,  which go into  effect  in  February  1998.  Such  public  filing  is a
condition to the closing of this Offering. Thereafter, the Company must continue
to meet  Nasdaq's  standards for  continued  listing.  The failure to meet these
standards may result in the delisting of the  Company's  securities  from Nasdaq
and trading,  if any, in the Company's  securities would thereafter be conducted
on the OTC Bulletin  Board.  If such delisting  occurs,  an investor may find it
more difficult to dispose of, or to obtain accurate  quotations as to the market
value of, the  Company's  securities.  In addition,  if the Common Stock were to
become delisted from trading on Nasdaq and the trading price of the Common Stock
were to fall below  $5.00 per share,  trading in the Common  Stock also would be
subject to the requirements of certain rules  promulgated under the Exchange Act
that require  additional  disclosure by  broker-dealers  in connection  with any
trades  involving a stock defined as a penny stock  (generally,  any  non-Nasdaq
equity security that has a market price


                                     - 12 -


<PAGE>

of less than $5.00 per share, subject to certain exceptions). Such rules require
the delivery,  prior to any penny stock  transaction,  of a disclosure  schedule
explaining the penny stock market and the risks associated therewith, and impose
various sales practice  requirements on broker-dealers  who sell penny stocks to
persons other than  established  customers and accredited  investors  (generally
institutions).  For these types of transactions,  the broker-dealer  must make a
special  suitability  determination  for the  purchaser  and have  received  the
purchaser's  written  consent to the  transaction  prior to sale. The additional
burdens imposed upon  broker-dealers  by such  requirements  may discourage them
from effecting  transactions in the Company's  securities,  which could severely
limit the liquidity of the Company's securities and the ability of purchasers in
this Offering to sell such securities in the secondary market.

         The net proceeds to the Company from the sale of shares of Common Stock
offered hereby are estimated to be approximately $[ ] ($[ ] if the Underwriters'
over-allotment option is exercised in full), assuming a public offering price of
$[ ] per share, and after deducting the  underwriting  discounts and commissions
and estimated  offering expenses payable by the Company.  The Company intends to

</TABLE>




         Approximately  $2,250,000  of the net  proceeds  of this  Offering  are
expected to be used to expand the Company's  sales and  marketing  activities by
hiring  additional  sales  and  marketing  personnel,   increasing  advertising,
participating  in trade  shows  and  other  promotional  activities,  developing
indirect   sales   channels  and  enhancing  the  Company's   customer   service
capabilities. See "Business--Sales and Marketing."

         Approximately  $2,000,000  of the net  proceeds  of this  Offering  are
expected to be used for  research  and  development,  including  enhancement  of
existing  features  and  development  of new  functions  for the VFC  family  of
products  and the  salaries  and  related  payroll  costs  for new and  existing
research and development personnel. See "Business--Research and Development."

         Approximately  $1,000,000  of the net  proceeds  of this  Offering  are
expected to be used to repay  institutional  debt owed to Merrill Lynch Business
Financial Services,  Inc. pursuant to a line of credit maintained by the Company
for up to $1,000,000 based upon eligible  receivables.  Interest on this debt is
calculated  at a per  annum  rate  equal  to the sum of  2.9%  plus  the  30-day
commercial paper rate.  Currently,  this per annum rate approximates  prime. The
facility expires in December 1997, and management  expects that the line will be
renewed  through July 1998.  The line of credit is  contingent  upon the Company
continuing  to meet certain  financial  covenants.  At November  28,  1997,  the
Company had outstanding borrowings of approximately $986,000,  including accrued
interest,  under this line of credit. See "Management's  Discussion and Analysis
of  Financial  Condition  and  Results  of  Operations--Liquidity   and  Capital
Resources."

         The balance of the net  proceeds of this  Offering  are  expected to be
allocated to working capital and general corporate  purposes,  including payment
of salaries, including salaries of its executive officers, and acquisitions.  As
of the date of this  Prospectus,  the Company has no agreement,  arrangement  or
understanding with respect to any acquisition.  If the Underwriters exercise the
over-allotment  option in full, the Company will realize additional net proceeds
of $____________,  which will be added to working capital.  Management will have
significant discretion regarding how and when such proceeds will be applied.

         The  allocation  of the net  proceeds of the  Offering  set forth above
represents the Company's best estimates based upon its current plans and certain
assumptions regarding industry and general economic conditions and the Company's
future revenues and  expenditures.  If any of these factors change,  the Company
may find it necessary or advisable to reallocate some of the proceeds within the
above-described categories.

         Proceeds not immediately required for the purposes described above will
be invested  temporarily,  pending  their  application  as described  above,  in
short-term United States government securities,  short-term bank certificates of
deposit,   money   market   funds  or  other   investment   grade,   short-term,
interest-bearing instruments.

         The  Company  anticipates,   based  on  currently  proposed  plans  and
assumptions relating to its operations  (including the costs associated with its
growth strategy), that the proceeds of the Offering,  together with its existing
financial  resources  and cash flow from  operations,  should be  sufficient  to
satisfy  its  anticipated  cash  requirements  through the end of the year 2000;
however,  there can be no assurance  that this will be the case.  The  Company's
actual cash  requirements  may vary  materially  from those now planned and will
depend upon numerous  factors,  including the general  market  acceptance of the
Company's new and existing  products and  services,  the growth of the Company's
distribution  channels,  technological  advances,  activities of competitors and
other factors. See "Management's  Discussion and Analysis of Financial Condition
and Results of Operations."


                                 DIVIDEND POLICY

         The Company has never  declared  or paid cash  dividends  on its Common
Stock.  The Company  expects to retain all available  earnings  generated by its
operations  for  the  development  and  growth  of its  business  and  does  not
anticipate  paying any cash  dividends  on its Common  Stock in the  foreseeable
future.


                           PRICE RANGE OF COMMON STOCK

                                    DILUTION

         As of September  30, 1997,  the  Company's  net tangible book value was
approximately  $(357,000),  or $(0.13) per share.  Net  tangible  book value per
share represents the amount of tangible assets less total  liabilities,  divided
by the number of shares of Common Stock outstanding.  After giving effect to the
consummation  of the  Offering  at an  assumed  price of $[ ] per  share  (after
deducting the  underwriting  discounts and  commissions  and estimated  offering
expenses payable by the Company),  the net tangible book value of the Company as
of September 30, 1997 would have been $[ ], or $[ ] per share.  This  represents
an immediate  increase in net tangible  book value of $[ ] per share to existing
shareholders  and an  immediate  dilution  of $[ ] per  share  to new  investors
purchasing  the  Common  Stock  in this  Offering.  Dilution  is  determined  by
subtracting net tangible book value per share after the Offering from the amount
of cash paid by a new investor for a share of Common Stock.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

         The discussion  and analysis  below should be read in conjunction  with
the  Consolidated  Financial  Statements  of the  Company,  including  the Notes
thereto, included elsewhere in this Prospectus.

COMPANY OVERVIEW

         The  Company  provides  electronic  document  management  software  and
systems to corporate and government  workgroups,  departments  and  enterprises.
Prior to 1994,  substantially all of the Company's business was derived from the
sale,  support,  and maintenance of INQUIRE/Text,  a full-text retrieval product
used for  storing,  indexing,  retrieving  and  managing  large  collections  of
documents on IBM and IBM-compatible mainframes. The Company expects INQUIRE/Text
revenues  to  decrease  over  time due to the  decreasing  reliance  of users on
mainframe  hardware and the maturity of the market. In 1994, the Company shifted
its focus to providing a broader  range of document and  information  management
solutions  deliverable  through  client/server  and  intranet  technology.  As a
result,  client/server,  intranet consulting  revenues and third-party  software
product revenues  increased from 23% of the Company's revenues in 1995 to 51% in
1996 and to 55% for the first three quarters of 1997.

         In January 1997, the Company introduced VFC, and began to market VFC in
the second quarter of 1997. The Company  anticipates that VFC will constitute an
increasing  percentage of the Company's  revenue for the foreseeable  future. In
December 1997, the Company entered into an agreement with Adobe to cross-license
and market  certain  technologies.  The  Company  expects  to receive  more than
$700,000 in consulting  fees for  modifications  to certain of its technology so
that  it can  be  incorporated  into  future  Adobe  products.  Upon  successful
completion  of these  modifications,  the  Company  will earn a  license  fee of
$1,000,000. Although the Company has received approximately 50% of the licensing
fees under this  agreement,  any  licensing  fees  received  by the  Company are
subject to refund if the Company fails to deliver an acceptable final product to
Adobe.  The Company  will not  recognize  any revenue with respect to these fees
until the product has been accepted and the fees are no longer refundable, which
is  expected to occur in 1998.  The  Company  will  recognize  revenue  from its
product  development  services in both 1997 and 1998 on a percent of  completion
basis.  Certain  components  of VFC  that  will be  licensed  to  Adobe  will be
incorporated in future Adobe products. In addition,  certain Adobe products will
display  a "VFC  Button"  that  will  provide  a  direct  link  to VFC or to VFC
marketing  information  if the user  does  not  have  VFC.  Adobe  will  receive
royalties  based on any sales of VFC arising out of this marketing  arrangement,
and will also receive commissions for any VFC sales that it makes directly.

         As of the  date  of  this  Prospectus,  VFC  has  been  sold  to  large
organizations with significant  document  processing  requirements,  such as the
Department  of Energy,  AT&T,  State Street Bank and the U.S. Army Signal Corps.
Due to limited sales and support  resources and the recent  introduction of VFC,
the  Company  has  focused  on  selling  VFC to  customers  that  have  multiple
applications that can utilize VFC. The Company expects that these customers will
help it in the future both as  references  and through  further sales within the
customers' organizations.  Evaluation copies of VFC software have been installed
at a number of large organizations. Most of these installations have resulted in
orders,  although a few customers have returned the evaluation  software without
placing an order. The sales cycle for initial sales of VFC has ranged from three
to six months.  The Company  believes  that the sales cycle for repeat  sales to
customers  may be shorter.  VFC is  licensed  at a price of $4,995.  The Company
plans to  increase  the  price of VFC with its next  release,  which  will  have
additional  features.  The Company also provides  support packages and extension
products at an additional  price. The Company offers annual  maintenance for VFC
at a cost of 20% of the purchase price.

         On October 11, 1995, the Company purchased substantially all the assets
and assumed certain  liabilities of Merex in  consideration of 210,000 shares of
the Company's common stock with a fair value estimated by the Company's Board of
Directors  at $1.125 per share.  The total  acquisition  cost was  approximately
$361,000,  including the direct costs of acquisition.  Approximately $60,000 was
allocated to identified acquired  intangibles,  $312,000 to goodwill,  including
purchase accounting adjustments of approximately $25,000 relating to termination
of the  Merex  office  lease,  and  $35,000  relating  to costs the  Company  is
obligated to pay in connection  with the  registration of securities held by the
former  shareholders of Merex.  For the year ended December 31, 1994,  Merex had
revenues of $2,174,000 and net income of $185,000.


                                     - 19 -


<PAGE>

         On July 22, 1997, the Company acquired all of the common stock of AMBIA
in  consideration  for 400,000 shares of the Company's  Common Stock with a fair
value as determined by the Company's Board of Directors of $5.425 per share. The
total acquisition cost was approximately $2,300,000,  including the direct costs
of the  acquisition.  Approximately  $25,000 was allocated to acquired  tangible
assets,  $60,000 to acquired intangible assets, and $2,213,000 to goodwill.  The
acquisition  was treated as a purchase.  For the eight months ended December 31,
1996 (AMBIA was  incorporated on May 1, 1996),  AMBIA's  revenues were $558,000,
and its net loss was $3,000.
AMBIA is now a subsidiary of the Company.

         At December  31,  1996,  the Company had a net  operating  loss ("NOL")
aggregating  approximately $5,347,000 available to effect future taxable income.
Under  Section 382 of the Internal  Revenue Code of 1986,  as amended  ("Code"),
utilization  of prior NOLs is limited after an ownership  change,  as defined in
Section  382,  to an  amount  equal  to  the  value  of the  loss  corporation's
outstanding stock immediately before the date of the ownership change multiplied
by the federal  long-term  tax-exempt  rate in effect  during the month that the
ownership change occurred. As a result of the AMBIA acquisition,  the Company is
subject to  limitations  on the use of its NOL as provided  under  Section  382.
Accordingly, there can be no assurance that a significant amount of NOLs will be
utilized by the Company.

         Future operating  results will depend upon many factors,  including the
demand for the Company's products, the effectiveness of the Company's efforts to
integrate  various  products it has  developed  or  acquired  and to achieve the
desired levels of sales from such product integration,  the level of product and
price  competition,  the length of the  Company's  sales cycle,  seasonality  of
individual  customer  buying  patterns,   the  size  and  timing  of  individual
transactions,  the delay or deferral of customer purchases and  implementations,
the  budget  cycles  of the  Company's  customers,  the  timing  of new  product
introductions and product  enhancements by the Company and its competitors,  the
mix of sales by products,  services and distribution  channels,  acquisitions by
competitors,  the ability of the Company to develop and market new  products and
control costs, and general domestic economic and political conditions.

RESULTS OF OPERATIONS

THREE MONTHS ENDED  SEPTEMBER 30, 1997 COMPARED TO THREE MONTHS ENDED  SEPTEMBER
30, 1996

         Revenues  increased by $535,000,  or 21%, from $2,502,000 for the three
months  ended  September  30,  1996 to  $3,037,000  for the three  months  ended
September 30, 1997. The Company derived revenues from consulting services, sales
of third party products, sales of INQUIRE/Text-related products and services and
maintenance  related  thereto,  and sales of the  Company's  software  products.
During the quarter,  VFC sales were minimal.  Revenues from consulting  services
and third party products,  as well as training,  increased by $261,000,  or 28%,
from $933,000 for the three months ended  September 30, 1996, to $1,194,000  for
the three months ended  September 30, 1997, due to an increase in product sales,
and, to a lesser extent, related consulting services. AMBIA contributed $253,000
to the Company's revenues for the quarter ended September 30, 1997.

         Gross profit  increased by $247,000,  or 21%, from  $1,168,000  for the
three months ended  September 30, 1996, to $1,415,000 for the three months ended
September  30,  1997.  The  increase  was due to the increase in revenue for the
quarter and the  acquisition  of AMBIA.  Gross  profit as a percent of sales was
consistent  for the three months ended  September  30, 1997 compared to the same
period in 1996.

         The Company continues to invest heavily in the development of VFC. This
resulted in an increase  of  $470,000,  or 167%,  in  research  and  development
expenditures  from  $281,000 for the three months ended  September  30, 1996, to
$751,000 for the three months ended September 30, 1997. The Company expects this
investment to increase  throughout  1998 and for the  foreseeable  future as VFC
product enhancements and capabilities are added.

         Selling,  general and administrative expenses increased by $679,000, or
92%, from $739,000 for the three months ended  September 30, 1996, to $1,418,000
for the three months ended  September 30, 1997. The increase is due primarily to
the  expansion  of the sales and  marketing  staff and an increase in  marketing
expenses  associated  with VFC. The Company  expects these  expenses to increase
throughout  1998 as new  versions of VFC are  released,  new sales  channels are
established and potential markets are explored.

         Interest income decreased by $9,000, or 39%, from $23,000 for the three
months ended  September 30, 1996 to $14,000 for the three months ended September
30, 1997. The decrease was due to lower balances of cash, cash equivalents,  and
short term  investments  during  the three  months  ended  September  30,  1997,
compared  to the  three  months  ended  September  30,  1996.  Interest  expense
increased  by $9,000,  or 450%,  from  $2,000 for the three month  period  ended
September  30, 1996 to $11,000 for the three  months ended  September  30, 1997.
This was due to the increased  utilization  of a line of credit during the third
quarter.

         As a  result  of the  foregoing,  the  Company  reported  a net loss of
$754,000 for the three months ended  September 30, 1997,  compared to net income
of $169,000 for the same period in 1996.

NINE MONTHS ENDED SEPTEMBER 30, 1997 COMPARED TO NINE MONTHS ENDED SEPTEMBER 30,
1996

         Revenues  decreased by $322,000,  or 4%, from  $7,355,000  for the nine
months  ended  September  30,  1996 to  $7,033,000  for the  nine  months  ended
September 30, 1997. The primary cause of this decrease was a decline in revenues
from consulting services and third party product sales of $735,000, or 26%, from
$2,867,000  for the nine months ended  September 30, 1996 to $2,132,000  for the
nine months ended September 30, 1997, resulting from the shift of certain of the
Company's  engineering  personnel to research and  development to accelerate the
development  of VFC. In  addition,  INQUIRE/Text-related  revenue  decreased  by
$118,000, or 5%, from $2,362,000 for the nine months ended September 30, 1996 to
$2,244,000 for the nine months ended  September 30, 1997. Due to the maturity of
the product and the market, the Company expects  INQUIRE/Text-related revenue to
continue to decline.  The  decrease in revenues  was  partially  offset by AMBIA
revenues of $253,000 from July 22, the date of its acquisition, to September 30,
1997 and by an increase in  intelligence-related  revenues of $278,000,  or 13%,
from  $2,127,000 for the nine months ended September 30, 1996, to $2,405,000 for
the nine months ended September 30, 1997.

         Gross profit increased by $53,000,  or 2%, from $2,943,000 for the nine
months  ended  September  30,  1996,  to  $2,996,000  for the nine months  ended
September 30, 1997. The slight increase was due to the acquisition of AMBIA.

         Research and development expenditures increased by $1,159,000, or 216%,
from $537,000 for the nine months ended  September  30, 1996, to $1,696,000  for
the nine months ended September 30, 1997. The Company continues to spend heavily
on the development of its VFC products.

         Selling,  general and administrative  expenses increased by $1,913,000,
or 95%,  from  $2,007,000  for the nine months  ended  September  30,  1996,  to
$3,920,000  for the nine months ended  September 30, 1997.  The increase was due
primarily to the expansion of the sales and  marketing  staff and an increase in
marketing expenses associated with VFC.

         As a  result  of the  foregoing,  the  Company  reported  a net loss of
$2,579,000 for the nine months ended September 30, 1997,  compared to net income
of $453,000 for the same period in 1996.

YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995

         Total revenues increased by $2,511,000, or 36%, from $7,049,000 for the
year ended December 31, 1995 to $9,560,000 for the year ended December 31, 1996.
Client/server related revenues increased by $3,270,000, or 204%, from $1,603,000
for the year ended  December 31, 1995, to $4,874,000 for the year ended December
31, 1996, in part  reflecting a full year of revenues from Merex.  Revenues from
third party client/server  related product sales increased by $898,000, or 357%,
from $251,000 for the year ended  December 31, 1995 to  $1,150,000  for the year
ended December 31, 1996. INQUIRE/Text-related revenues decreased by $773,000, or
14%, from $5,446,000 for the year ended December 31, 1995, to $4,672,000 for the
year ended  December 31, 1996.  The decrease was primarily  attributable  to the
decline in maintenance contracts.

         Gross profit increased by $1,220,000, from $2,883,000, a 42% margin, at
December 31,  1995,  to  $4,103,000  for the year ended  December 31, 1996.  The
increase in the gross profit margin was due primarily to


                                     - 21 -


<PAGE>

increased commercial client/server consulting during 1996, offset in part by the
decline in high margin INQUIRE/Text maintenance revenues.

         Research and development  expense increased by $629,000,  or 336%, from
$187,000 for the year ended  December  31, 1995,  to $816,000 for the year ended
December 31, 1996.  The principal  cause of the increase was the  development of
VFC software products.

         Selling,  general and administrative expenses increased by $212,000, or
8%, from  $2,657,000  for the year ended December 31, 1995 to $2,869,000 for the
year ended  December 31, 1996.  The increase was due primarily to an increase in
the sales staff for the planned release of VFC.

         Interest  income  decreased by $23,000,  or 19%,  from $119,000 for the
year ended  December 31, 1995, to $96,000 for the year ended  December 31, 1996.
The decrease was primarily due to a lower average  market yield on cash and cash
equivalents in 1996 compared to 1995.  The Company  invested only in short-term,
highly liquid money market instruments.

         Interest  expense  decreased by $13,000,  or 54%,  from $24,000 for the
year ended  December  31, 1995 to $11,000 for the year ended  December 31, 1996.
The expense was related  primarily  to capital  equipment  leases  which  expire
through 1998.

         Net income increased by $372,000, or 284%, from $131,000 for the year
ended December 31, 1995, to $503,000 for the year ended December 31, 1996. The
increase in net income was due to the factors discussed above. As a result of
preferred stock dividends of $120,000 and $58,000 paid in 1995 and 1996,
respectively, net income available to holders of common stock amounted to
$11,000, or $.01 per share, and $445,000, or $.20 per share ($.18 fully
diluted), respectively. During 1996, all of the outstanding preferred stock was
converted into common stock and, therefore, no preferred stock dividends will be
paid in 1997.

YEAR ENDED DECEMBER 31, 1995 COMPARED TO DECEMBER 31, 1994

          Total revenues  decreased by $453,000,  or 6%, from $7,502,000 for the
year ended December 31, 1994 to $7,049,000 for the year ended December 31, 1995.
The primary cause was a $971,000  decline in  INQUIRE/Text  related revenue from
the prior year,  primarily  reflecting  reduced product license fees,  offset by
client/server related consulting revenue, which increased 79% to $1,364,000 from
$763,000 in the prior year. The acquisition of Merex in October 1995 resulted in
approximately  $550,000 in  client/server  consulting  revenue during the fourth
quarter of 1995,  which  represents  most of the increase.  Total fourth quarter
revenues increased from $1,837,000 in 1994 to $2,156,000 in 1995.

         Gross  profit   decreased  by  $532,000,   or  16%,   from   $3,415,000
(representing  a 46%  gross  margin)  to  $2,883,000  (representing  a 41% gross
margin) for the year ended  December 31,  1994.  The decrease was due in part to
the effect of a 6% decline in revenues and also certain lower margin  government
contracts  acquired from Merex. The Company changed its methodology for overhead
allocation in 1995 to more accurately reflect certain indirect costs of revenues
which resulted in a reclassification  of the 1994 statement of operations from a
gross profit of 40% to a revised 45% but had no effect on operating income.

         Research and development  expense  decreased by $221,000,  or 54%, from
$408,000  for the year ended  December  31, 1994 to $187,000  for the year ended
December 31, 1995. The principal cause of the decrease was cost reduction due to
outsourcing  of  mainframe-related  computer costs in the fourth quarter of 1994
which had a full year impact on 1995.  The Company  believes that  substantially
all of the impact of cost reduction has been realized.

         Selling,  general and administrative expenses increased by $175,000, or
7%, from  $2,482,000 for the year ended December 31, 1994, to $2,657,000 for the
year ended  December  31,  1995.  The  increase  was due in part to the costs of
building a marketing and sales force, an increase in consulting fees relating to
execution of the Company's  strategic  plan to expand into  client/server  based
consulting, and the impact of integration costs arising


                                     - 22 -

<PAGE>

from the Merex  acquisition.  The decline in revenues  and  increase in expenses
resulted in an increase in expenses to 38% from 33% in the prior year.

         Interest  income  increased by $73,000,  or 159%,  from $46,000 for the
year ended  December 31, 1994, to $119,000 for the year ended December 31, 1995.
respectively. The increase was primarily due to a higher average balance of cash
and cash equivalents in 1995 over 1994. The Company invested only in short-term,
highly liquid money market instruments. Interest expense decreased to $24,000 in
1995 from $42,000 in the prior year. The expense is primarily related to certain
capital equipment leases which expire through 1998.

         Net income  decreased by $387,000,  or 75%,  from $518,000 for the year
ended  December 31, 1994 to $131,000 for the year ended  December 31, 1995.  The
decrease was due to the factors  discussed  above. The Company expects the Merex
acquisition to favorably impact net income in 1996.

LIQUIDITY AND CAPITAL RESOURCES

         At September 30, 1997, the Company had cash, cash equivalents and short
term  investments  of $703,000 and a working  capital  deficit of $892,000.  The
Company  maintains  a line of  credit  with  Merrill  Lynch  Business  Financial
Services, Inc. for up to $1,000,000 based upon eligible receivables. Interest on
this debt is  calculated  at a per annum  rate equal to the sum of 2.9% plus the
30-day commercial paper rate. Currently, this per annum rate approximates prime.
The facility expires on December 31, 1997, and management  expects that the line
will be renewed  through July 1998.  The line of credit is  contingent  upon the
Company  continuing to meet certain financial  covenants.  At November 28, 1997,
the Company had  outstanding  borrowings of  approximately  $986,000,  including
accrued interest, under this line of credit.

         Net  cash  used in  operating  activities  for the  nine  months  ended
September  30,  1997 of  $2,293,000  was due to the  Company's  net loss for the
period of $2,579,000, and an increase in accounts receivable, offset by non-cash
expenses such as depreciation and  amortization,  and a significant  increase in
accounts payable.  Accounts  receivable are derived from sales made to customers
on 30-day (or less) terms. Net cash provided by investing activities of $182,000
for the nine months  ended  September  30, 1997 was derived  primarily  from the
maturity  of short  term  investments,  offset  by  purchases  of  property  and
equipment.  Net cash provided by financing of  $1,123,000  came from proceeds of
short-term borrowing for the nine months ended September 30, 1997.

         Net cash provided by operating  activities  for the year ended December
31, 1996 of $1,140,000 was primarily due to the Company's net income, a decrease
in accounts  receivable,  significant non-cash expenses such as depreciation and
amortization,  and an  increase  in  accrued  expenses,  partially  offset  by a
decrease in deferred revenue. Net cash used in investing activities for the year
ended  December  31, 1996 of  $1,396,000  was due to the  purchase of short term
investments  and property and equipment.  Net cash provided by financing for the
year ended December 31, 1996 of $46,000 was due to the issuance of stock, offset
by payments on capital lease  obligations  and  preferred  stock  dividends.  At
December  31,  1996,  the Company had cash,  cash  equivalents,  and  short-term
investments of $2,213,000.

         The Company incurred net losses of $2,579,000 for the nine months ended
September 30, 1997 and was in a negative working capital position of $892,000 at
September 30, 1997. Since  September,  the Company has continued to incur losses
and management's projections indicate that the Company will continue to generate
operating  losses and  negative  cash flow,  although at a declining  rate.  The
Company anticipates,  based on currently proposed plans and assumptions relating
to its operations  (including the costs  associated  with its growth  strategy),
that  the  proceeds  of the  Offering,  together  with  its  existing  financial
resources  and cash flow from  operations,  should be  sufficient to satisfy its
anticipated cash requirements  through the end of the year 2000. However,  there
can be no  assurance  that this  will be the case.  The  Company's  actual  cash
requirements  may vary  materially  from those now  planned and will depend upon
numerous  factors,  including the general market acceptance of the Company's new
and existing  products and services,  the growth of the  Company's  distribution
channels,  the technological  advances and activities of competitors,  and other
factors.

                                    BUSINESS

         The  Company  provides  electronic  document  management  software  and
systems to corporate and government workgroups, departments and enterprises. The
Company's newest product,  VFC, has been designed to address what  DataPrOpinion
has called one of the biggest  problems  facing global  organizations:  the fact
that their critical assets are often contained in documents  stored in disparate
and incompatible  systems.  According to  DataPrOpinion,  "accessing and sharing
that information  among different  departments  across the enterprise has been a
nightmare."

          VFC is a family of intranet-based  software  products that,  together,
will  enable  users  to  easily  retrieve,  organize  and  share  desktop  files
irrespective of the location or type of document management system in which they
are  stored  with  virtually  no  integration  effort  and  without  the need to
replicate documents. The VFC family of products consists of the VFC Document Web
Server,  extensions  and  enablers.  The VFC Document Web Server is the heart of
VFC, and is required in order to utilize all other  components of VFC. This core
package  consists of software  installed on a server that  establishes  links to
documents,  organizes  access to stored  information  and acts as an independent
document  sharing  system.  The Company has been  shipping  the VFC Document Web
Server since the second quarter of 1997. Extensions are software components that
are installed on an individual  user's computer to add  functionality to the VFC
Document  Web Server.  In October  1997,  the Company  began  shipping its first
extension  and expects to introduce  other  extensions  in the future.  Enablers
provide  the  capability  to bridge  multiple  document  management  systems  or
repositories.  The first  enablers are expected to be available  for shipment in
the second quarter of 1998.

         The Company's  VFC  technology  has been  endorsed by leading  industry
vendors,  including  Lotus,  PC DOCS,  Verity,  and  NovaSoft,  and has received
numerous favorable  industry trade analyst and press reviews.  At the April 1997
AIIM trade show,  with more than 35,000  attendees and 325  exhibitors,  Imaging
World  Magazine  identified  VFC as "#1 TO  WATCH".  VFC has been  sold to large
organizations  with significant  document  processing  requirements  such as the
Department of Energy, AT&T, State Street Bank and the U.S. Army Signal Corps.

         In December 1997, the Company and Adobe, a major software  company with
reported 1996  revenues of greater than $750 million,  entered into an agreement
to cross  license  and  market  certain  technologies.  Adobe  is a  significant
presence in the Internet  marketplace  with,  according  to Adobe,  more than 20
million  downloads  of its  Adobe  Acrobat  Reader  viewing  product.  Under the
agreement,  the Company expects to receive more than $700,000 in consulting fees
for  modifications  to certain of its technology so that it may be  incorporated
into certain Adobe products.  Upon successful completion of these modifications,
the Company will earn a license fee of  $1,000,000.  Certain  components  of VFC
that will be licensed to Adobe will be incorporated in future Adobe products. In
addition, certain Adobe products will display a "VFC Button" that will provide a
direct  link to VFC or to VFC  marketing  information  if the user does not have
VFC.  Adobe will receive  royalties  based on any VFC sales  arising out of this
marketing arrangement,  and will also receive commissions for any VFC sales that
it makes directly.

         For nearly  thirty  years,  the Company has  developed and sold its own
products  and acted as a VAR of  client/server  and  Internet/intranet  document
systems  products.  Recently,  the Company made two  acquisitions to broaden its
product and service  offerings:  Merex,  acquired  in October  1995,  and AMBIA,
acquired  in July 1997.  Merex  provided a staff  experienced  in  Internet  and
client-server  document  technologies,  and AMBIA  provided both an  experienced
technical staff and products focusing on document creation,  collaboration,  and
presentation.  The Company now provides a range of services, including training,
customer  support,  and  consulting  to ensure that  customers  achieve the full
benefits of the Company's products. See "Certain Transactions."

INDUSTRY BACKGROUND

         Document  management  products  were  originally  introduced  to  solve
problems  associated  with  the  production  of  complex  and   mission-critical
documentation,  such as new drug  applications  or aircraft  operating  manuals.
These documents are characterized not only by complex content such as graphs and
images as well as text, but also by a heavily controlled or regulated process by
which documents are written and reviewed. These document management systems have
been  expensive to procure and difficult to install and  implement  because they


                                     - 25 -

<PAGE>

require  unique user  interfaces  for which  specialized  training is necessary.
Their usage is controlled centrally, with little flexibility for the end user.

         Many  people  who work in office  environments  are  familiar  with the
difficulties  of filing and retrieving  documents from their hard drives or from
network file systems.  Individuals are forced to remember  artificial file names
and folder or  directory  locations  because  the  documents  generally  are not
organized in an intuitive manner.  Naming and storage  requirements  might apply
only to an individual's own workgroup or department,  or they might apply across
the enterprise. Systems to address the needs of these users need to be simple to
deploy and easy to  administer.  They also need to be  scalable  to  accommodate
wider deployment of applications and additional users.

         With the increasing departmental, as opposed to enterprise-wide, use of
document management systems, it is not uncommon for different departments within
an  enterprise  to  use  different  document  management  systems  or  to  store
electronic documents in separate  repositories that are tailored to the needs of
the individual  department.  For example, an organization's legal department may
use one document management system specialized for legal applications, while the
engineering  department uses another for engineering drawings.  Without a bridge
to link the two systems,  the two  departments  are unable to share  information
electronically.

Attempts to address these issues have included:

         Developing  Web Browser  Access to Document  Management  Systems.  Some
vendors of  document  management  systems  have  introduced  add-on Web  browser
products  that allow users to access files stored on that vendor's  system.  The
Web-based  user  interface is familiar to the user,  but this  solution does not
permit information to be shared across different document management systems.

         Posting  Documents on the Company's Web Site.  Many  organizations  are
using their  internal  Web sites for  electronic  publication  of commonly  used
documents such as human resource  policy manuals.  The primary  drawback is that
"posting"   documents  to  the   organization's   Web  site  typically  requires
intervention of a "Webmaster," whose responsibility is to maintain the Web site.
The  Webmaster may become a bottleneck  as the Web site grows.  Also,  documents
posted to the Web site are usually not updated  concurrently  with the  original
document.  For example,  when the human resources  department updates its policy
manual,  there is  typically a delay  before the new version is converted to the
appropriate format and approved for posting on the Web site.

         Using  Groupware  Products.  Groupware  products are designed to foster
collaboration among members of workgroups.  Examples include Lotus Notes, Novell
Groupwise 5, Netscape SuiteSpot and Microsoft  Exchange.  Although some of these
products incorporate some document management  functionality,  they still create
"islands" of  information  since users are able to access only that  information
residing within the groupware product's own proprietary databases.

         The  Company  created  VFC to  provide  a  reasonably  priced,  easy to
implement solution to the problems  associated with the exchange and bridging of
information  between  parties that can benefit from access to that  information,
irrespective of where it is stored.

VIRTUAL FILE CABINET

         VFC is a family of  intranet-based  software  products that,  together,
will  enable  users  to  easily  retrieve,  organize  and  share  desktop  files
regardless of the location or type of document  management  system in which they
are stored with  virtually no  integration  effort and without the  necessity of
replicating documents.

     The  VFC family of products consists of:

     o    The VFC Document Web Server. This is the heart of VFC, and is required
          in order to utilize all other  components  of VFC.  This core  package
          consists of software  installed on a server that establishes  links to
          documents,  organizes  access  to  stored  information  and acts as an
          independent  document  sharing  system.  The VFC  Document  Web Server
          interacts  with the user's  desktop via 

                                     - 26 -


<PAGE>

          a browser such as Netscape or Microsoft Internet Explorer. The Company
          has been shipping the VFC Document Web Server since the second quarter
          of 1997.

     o    Extensions.  Extensions are software  components that are installed on
          an individual user's computer. Extensions add functionality to the VFC
          Document  Web Server.  In October  1997,  the Company  began  shipping
          Re:mark as an extension to enable  seamless  electronic  annotation of
          Adobe  Acrobat  Portable  Document  Format  ("PDF")  documents.  Other
          extensions are expected to be introduced in the future.

     o    Enablers.  Enablers provide the capability to bridge multiple document
          management systems or repositories. The first enablers are expected to
          be available for shipment in the second quarter of 1998.

     VFC  combines the following features:

     o    Adaptability to Individual Users and Groups.  Using VFC, an individual
          can  search  all  of  the  servers  of an  enterprise  for  electronic
          documents or containers without leaving his or her office,  then place
          the  documents  into a  private  virtual  office,  where  they  can be
          organized according to personal style and preferences.  Departments or
          workgroups can organize a space that is optimal for the group.

     o    Instant Updates of Documents. If the original document is updated, all
          of the  "virtual  documents"  residing in every  virtual  location are
          updated at the same time.  Thus,  every user  always has access to the
          most current version of a document.

     o    Eliminates  Webmaster  Bottleneck.  Since  users can  easily  post new
          documents to the VFC Document Web Server  without  converting  them to
          special  formats,  such as HTML,  intervention  by a Webmaster  is not
          required and the delays  typically  associated with such  intervention
          are avoided.

     o    Optimizes Use of System Resources. Each document that is placed in the
          virtual  office  is linked to the  original.  Each link in the  user's
          virtual  office  behaves and looks just like the original.  No copy of
          the  document  is made.  This  saves  significant  network  and client
          resources  because  only a  single  copy  of a  document  needs  to be
          maintained for it to be available to everyone who needs it.

     o    Minimal  Implementation  Costs.  VFC is delivered ready to plug into a
          user's network. No programmers or developers are needed, and users can
          capture and share  documents  immediately.  VFC is designed  for rapid
          implementation,  requiring  low  overhead  and  a  minimal  amount  of
          training.

     o    Universal  Desktop  Access.  The  intranet  infrastructure  behind VFC
          provides  the  interface  for the  information-sharing  functionality.
          Essentially  a private  Web site,  VFC is an  intranet  solution  that
          provides all the benefits of Web access,  including  hypertext linking
          and cross-platform  connection via a Web browser,  and allows users to
          "jump" to any  location  at the  click of a mouse  and view  documents
          regardless of their original format or where they are stored.

     o    Easy-to-Understand  Organizational  Scheme.  Under  the  VFC  document
          management  format,  documents  are  stored  in a  hierarchy  of icons
          depicted as buildings,  offices, file cabinets, folders and documents.
          This  hierarchy is  meaningful  to anyone  familiar with a traditional
          office and filing system.

     o    Easy-to-Use  Search  Tools.  In  addition  to  navigating  through the
          virtual  office  hierarchy to locate a document,  users can employ the
          VFC  search  tool  to  locate  any  document  easily  and  quickly  by


                                     - 27 -

<PAGE>

          specifying  simple  search  criteria such as the  document's  title or
          author or by  searching  the  document's  content for words or phrases
          specified by the user.

     o    Effective,  Flexible Security Mechanisms. VFC can be managed centrally
          by a single system  administrator who can restrict access via password
          protection and group  permission.  The  administrator  can also assign
          administrative  rights to certain individuals such as department heads
          or  workgroup  leaders,  who in turn can grant or  restrict  access to
          individuals  within  their  groups.  An  individual  who has not  been
          granted  read  access  to a  particular  document  will  not  only  be
          prevented from opening and viewing the document,  but also will not be
          informed of its  existence  since it will not appear on a results list
          generated from a search command.

     o    Easily  Expandable  Functionality.  Extensions  will allow VFC to take
          advantage of functionality in other software or systems.  For example,
          using the  Company's  Re:mark  extension,  users can  collaborate  and
          simultaneously  annotate  documents  viewed  with  the  Adobe  Acrobat
          Reader.

     o    Ability to Link Diverse  Document  Systems.  The VFC enabler  bridging
          technology,  when  introduced,  will permit users to access  documents
          stored in  multiple  and  disparate  document  management  systems  or
          repositories from their personal VFC desktop as if all of the separate
          systems and repositories were one.

OTHER PRODUCTS

     Re:mark.  Re:mark is a plug-in  product  for Adobe  Acrobat  software  that
     enables users to mark up, redline and review documents  electronically in a
     workgroup setting. By annotating any document in PDF, Re:mark enables users
     to type text on the document page, draw on the document,  indicate approval
     of the document  itself or specific  sections,  attach any file anywhere in
     the  document,  consolidate  comments from  multiple  reviews,  personalize
     comments  and  set  annotation   security.   Redlining   features   include
     highlighting,  strike-through and "sticky notes." Annotations may be shared
     among users.

     Compose.  Compose is a suite of plug-in  tools for Adobe  Acrobat  Exchange
     that automate and streamline a variety of document  production  tasks, such
     as the creation of tables of contents,  hyperlinks,  document indexes,  and
     other document navigation features.

     Aerial. Aerial enables Adobe Acrobat to print any document that needs to be
     magnified by formatting  the document for printing on multiple  pages which
     are then pieced together to form one page, such as a large spreadsheet or a
     CAD  drawing.  Aerial  also  enables  Adobe  Acrobat to format  tables into
     spreadsheets,  and  converts  PDF to a text  format that can be edited with
     Microsoft Word or other word processors.

     Signet. Signet is a security solution for Web or CD-ROM publishers who want
     to permit only  authorized  users to read their  documents.  Signet  allows
     publishers  to control  the time and  circumstances  of the  expiration  of
     users' privileges.

     INQUIRE/Text.  INQUIRE/Text  is a  full-text  retrieval  product  used  for
     storing, indexing,  retrieving, and managing large collections of documents
     on IBM and IBM-compatible mainframes.  INQUIRE/Text software is widely used
     by major  companies,  utilities,  hospitals,  and  government  agencies for
     automating   document-centered   applications   such  as  on-line  manuals,
     legislative  tracking  and  regulatory   compliance,   library  management,
     litigation   support,   medical   records,   and  government  and  military
     intelligence. The system has been installed at over 350 sites.

     WebINQUIRE.  WebINQUIRE  is an extension  product that provides Web browser
     access to  INQUIRE/Text  collections.  It enables  users to  utilize  their
     mainframe as an intranet  superserver  with all the search  capabilities of
     INQUIRE/Text.  WebINQUIRE  permits users to store  documents  created using
     desktop  software  on a mainframe  computer,  retrieve  documents  from the
     mainframe and edit them on their desktop using desktop  applications,  such
     as Microsoft  Excel and Microsoft  Word. In addition,  


                                     - 28 -

<PAGE>

     WebINQUIRE's  search formats and views can be easily  customized.  Although
     WebINQUIRE and other INQUIRE/Text  options carry a high gross margin,  they
     are not expected to amount to a  significant  percentage  of the  Company's
     future revenues.

         In addition to its proprietary  products  described above, the Company,
acting as a VAR,  also sells third party  products  such as Verity's  Search '97
Information  Server, PC DOCS software and Documentum  software.  This allows the
Company to provide  document  management  solutions  that are  tailored  to each
customer's needs.

         In  conjunction  with product  sales,  the Company  provides  training,
maintenance  and  technical  support  services,   including  business  analysis,
requirements  definition,   design  and  development.  In  some  instances,  the
Company's  services are provided in  connection  with the sale of the  Company's
products  and  those  of  third  parties  for  whom it acts as a VAR.  In  other
instances,  product sales are made in connection with the solutions  provided by
the Company's consulting services.

STRATEGY

         The Company's  objectives are to establish VFC as the de facto industry
standard  for  document  access and to become a leading  provider of  electronic
document management  software and systems.  To accomplish these objectives,  the
Company intends to:

         Maintain  Technological  Leadership.  The Company's  technology enables
organizations  to effectively  manage,  share and store  critical  documents and
information  across the  enterprise.  The Company intends to continue to develop
what it  believes  are  innovative  technologies  and  features  to address  the
specific  document  management  needs of  organizations.  The  Company  plans to
continue  to develop new  products  and to improve its  existing  products.  The
Company  intends to continue to invest in its technology and to use a portion of
the proceeds of this Offering for research and development.

         Add Strategic Relationships.  To facilitate the adoption of VFC as a de
facto  industry  standard,  the  Company  plans to  continue  to form  strategic
relationships with providers of document management software applications, tools
and services.  The Company believes that strategic  relationships,  such as that
formed with Adobe, enhance the visibility of the Company's products and leverage
the Company's sales and marketing efforts by expanding the number of salespeople
marketing the Company's  products without burdening the Company with the need to
identify and hire a large sales force. The Company believes that the development
of these relationships will enable the Company to devote additional resources to
product development and marketing activities.

         Expand Sales and Marketing Capabilities.  The Company intends to expand
its sales and marketing  capabilities  by creating  additional  VAR and original
equipment manufacturer relationships, expanding its direct sales force, offering
training, and participating in trade shows. The Company intends to use a portion
of  the  proceeds  from  this  Offering  to  enhance  its  sales  and  marketing
capabilities.

         Acquisitions.  In October  1995,  the  Company  acquired  Merex,  which
provided  electronic  document  management  solutions to business and government
customers,  and in July 1997, the Company acquired AMBIA, a leading developer of
Adobe Acrobat add-on products and services.  The  acquisitions of both AMBIA and
Merex brought  experienced  management  and staff,  a diverse client base and an
established  market reputation to the Company.  The Company plans to continue to
pursue acquisitions of businesses, products and technologies that complement the
Company's existing business. As of the date of this Prospectus,  the Company has
no agreement, arrangement, or understanding with respect to any acquisition. See
"Certain Transactions."

SALES AND MARKETING

         The Company  conducts its sales and marketing  efforts  through several
channels, including a network of VARs, its own sales force, marketing alliances,
marketing communications and training programs. The Company's VARs and its sales
force receive  direct  support from the Company's  technical  staff.  Consulting
services  leads are provided to the Company by those vendors for whom it acts as
a VAR.  The Company  believes  this  diversity of 


                                     - 29 -

<PAGE>

sales and marketing  channels permits it to distribute its products and sell its
services in an efficient and effective  manner,  while reducing  reliance on any
one sales channel.

     Value-added Resellers. The Company's primary sales channel for its products
     is its VARs.  The Company's  VARs market and resell the Company's  products
     and offer training, installation, implementation

     and  customization  services  to  their  own  contacts  and to  prospective
     customers identified by the Company. The Company manages a program to train
     and certify all of its VARs. It also conducts  joint  marketing  campaigns,
     including  direct  mail and trade show  appearances,  with its VARs.  As of
     December  1997,  the  Company had  relationships  with VARs,  including  GE
     Capital IT Solutions and BTG Inc. VARs buy VFC and other  products from the
     Company at a discount from the suggested retail price.

     Company Sales Force. The Company has a sales force of 15 people,  including
     field sales,  telemarketing,  channel liaisons,  and sales management.  The
     channel   liaisons  work   specifically   with  the  Company's   VARs.  The
     telemarketing  staff qualifies  prospective  customers,  schedules  product
     demonstrations,  and refers prospective  customers to a VAR or, if a VAR is
     not in place in the particular territory, to the Company's sales force. The
     Company's sales force also sells upgrades and add-on  products,  and refers
     leads  for  services  opportunities  to VARs or to the  Company's  services
     divisions.

     Marketing  Alliances.  The Company  itself is a VAR of products  from other
     software companies,  including Adobe, Verity,  Documentum, and PC DOCS. The
     Company incorporates these products into its document management solutions.
     The Company earns a reseller commission ranging from 10% to 40% on sales of
     these products.

     Marketing Communications.  The Company generates awareness of, and interest
     in,  its  products  and  consulting   services  through  public  relations,
     telemarketing,  periodic direct mail campaigns,  seminars,  trade shows and
     other marketing efforts. In 1997, the Company conducted joint seminars with
     Adobe,  cooperative direct mail campaigns with several of its VFC VARs, and
     exhibited at trade shows including Lotusphere,  AIIM, Documation,  Seybold,
     and Internet World West.

     Training.  The Company  believes  that  training  is an integral  part of a
     complete customer  solution,  and that students in each class are potential
     customers for the Company's other products and services.  Consequently,  in
     1996,  the  Company  established  a  training  division  to offer  customer
     training  in the Adobe  Acrobat and Verity  Topic  products.  In 1997,  the
     Company  added  training  for the  Company's  own products  including  VFC,
     Re:mark, Compose,  INQUIRE/Text, as well as Adobe's Framemaker,  Framemaker
     SGML,  and Photoshop  products.  The Company  employs a full-time  training
     staff  and  maintains  a  state-of-   the-art  training   facility  at  its
     headquarters office in Fairfax, Virginia. The training division also offers
     courses at customer  locations.  The Company is  currently  the  authorized
     Verity East Coast Training Center.

         The  Company   sells  its   products   under  a  variety  of  licensing
arrangements.  For domestic sales of VFC, Re:mark, Compose, Aerial and Signet, a
shrink-wrap  license is used to protect  the  Company's  proprietary  rights and
limit  liability.  For all other  products,  the  Company  enters  into  written
agreements with its customers  containing similar  provisions.  The Company also
employs  evaluation and beta test  agreements that provide for the protection of
the Company's intellectual property. For consulting services, the Company enters
into written agreements with its customers,  which provide for  indemnification,
limits on liability,  payment terms, period of performance,  and other terms and
conditions.

         The  license  of the  Company's  software  products  and the use of the
Company's systems solutions  services generally require the Company to provide a
significant  level of education to prospective  customers  regarding the use and
benefits  of  the  Company's  products,  resulting  in  a  lengthy  sales  cycle
(typically  between three and six months).  Additionally,  the implementation by
customers of the  Company's  products may involve a  significant  commitment  of
resources by such customers over an extended period of time. For these and other
reasons, the sales and customer implementation cycles are subject to a number of
significant delays over which the Company has little or no control. Delay in the
sale or customer  implementation  of the Company's  products and services  could
have a material  adverse  effect on the Company's  business and  operations  and
cause the  Company's  operating  results to 


                                     - 30 -


<PAGE>

vary significantly from quarter to quarter. Therefore, the Company believes that
its quarterly operating results are likely to vary in the future.

         The sales cycle for  initial  sales of VFC has ranged from three to six
months.  The  Company  believes  that the sales  cycle for  repeat  sales may be
shorter. VFC is licensed at a price of $4,995. The Company plans to increase the
price of VFC with its next release,  which will have  additional  features.  The
Company also provides support  packages and extension  products at an additional
price.  The Company  offers annual  maintenance  for VFC at a cost of 20% of the
purchase price.

CUSTOMERS

         The  Company  targets  both  commercial  and  government  markets.  The
Company's  products and  consulting  services are used by many major  companies,
including Ford,  Allen-Bradley,  Boeing, Nabisco, AT&T, Chase, State Street Bank
and Riggs Bank, and by government organizations,  including NASA, the Department
of Energy,  the U.S. Army Signal Corps,  the  Government  Accounting  Office and
various  agencies  within  the  intelligence  community.   Sales  to  government
customers  represented  approximately  45% of revenues in 1996 and approximately
39% for the first nine months of 1997;  however,  no one customer  accounted for
more than 10% of the Company's revenues in either period.

         The Company has repeat  business  from a number of its  customers,  and
management  believes that there is a high degree of customer  satisfaction  with
its products, services and solutions. The Company's existing services, training,
and products provide a base of business that the Company expects will complement
VFC product sales. Developing custom solutions for customers keeps the Company's
technical   professionals   abreast  of  client  needs,  which  facilitates  the
conception and development of new products,  such as VFC, and the improvement of
existing products.

         Certain of the Company's  contracts with government  organizations  are
competitively  awarded  after  a  formal  bid  and  proposal  competition  among
qualified bidders.  These government contracts may be either  cost-reimbursement
contracts (both cost-plus-fixed-fee and cost-plus-award-fee), time and materials
contracts, and fixed price contracts.  Cost-plus-fixed-fee contracts provide for
the reimbursement of incurred costs during contract  performance,  to the extent
that such costs are allowable and allocable, and the payment of a fixed fee. The
size of the fee is limited  by federal  guidelines  to a set  proportion  of the
contract  value.   Cost-plus-award-fee   contracts  typically  provide  for  the
reimbursement  of costs with a base fee and an additional fee that is based upon
a periodic  evaluation of the Company's  performance against specified criteria.
Under time and  materials  contracts,  the  Company  agrees to  provide  certain
categories  of  labor  that  satisfy   established   education  and   experience
qualifications  at a fixed hourly rate.  In these cases,  the Company  bears the
risk that costs may differ from the fixed hourly rate, and the Company  realizes
all of the benefits or detriment  resulting  from  decreases or increases in the
cost of performing the work. Under fixed-price contracts,  the Company agrees to
perform  certain  work for a fixed  price  and,  accordingly,  realizes  all the
benefit or  detriment  resulting  from  decreases  or  increases  in the cost of
performing the work.

         The Company's government contracts contain standard termination clauses
that permit the  government  to terminate  the  contracts  at any time,  without
cause,  for the  convenience  of the  government.  The  Company  has not had any
contracts terminated for convenience. In addition,  government contracts require
compliance with various procurement regulations. The adoption of new or modified
procurement  regulations  could  materially  adversely  affect  the  Company  or
increase its costs of competing  for or  performing  government  contracts.  Any
violation of these regulations could result in the termination of the contracts,
imposition  of fines,  and/or  debarment  from  award of  additional  government
contracts.  Most  government  contracts  are also  subject  to  modification  or
termination  in the event of changes in funding,  and the Company's  contractual
costs and revenue are  subject to  adjustment  as a result of audits by the DCAA
and other  government  auditors.  The DCAA routinely  audits  cost-reimbursement
contracts  to verify that costs have been  properly  charged to the  government.
Further, government contract awards may be subject to protest by competitors.

         Many of the  Company's  government  contracts  require  the Company and
certain of its  employees to maintain  security  clearances  complying  with the
requirements of various government agencies.

RESEARCH AND DEVELOPMENT

         The  Company's  research  and  development  programs  are  intended  to
anticipate and take advantage of new technologies, and to anticipate and respond
to market requirements. The Company believes that its future success will depend
in large part on its ability to maintain and enhance its  leadership in document
management  and related  technologies  and to develop new products  that meet an
expanding range of customer requirements.

         The  market  for the  Company's  products  is  characterized  by  rapid
technological  developments,  evolving industry  standards,  changes in customer
requirements,  and frequent new product  introductions and  enhancements,  which
often lead to  product  obsolescence.  The  Company  believes  that the speed of
technological  advancement in its industry requires a significant  investment in
research and development in order to maintain its competitive  product position.
The Company will continue to invest  substantially in product  development as it
believes  that its future  success  will  depend upon its ability to develop and
market new products and  enhancements to existing  products on a  cost-effective
and timely basis.  Software development expenses increased from $187,000 in 1995
to $816,000 in 1996.  For the nine months ended  September 30, 1997, the Company
expended $1,696,000 on software development.

         Due to the  complexity  and  sophistication  of the Company's  software
products,  the Company's  products  from time to time contain  defects or "bugs"
that can be  difficult  to correct.  Furthermore,  as the Company  continues  to
develop and enhance its  products,  there can be no  assurance  that the Company
will be able to identify and correct defects in such a manner as will permit the
timely  introduction  of such products.  Moreover,  the Company may from time to
time discover  defects only after its systems have been used by many  customers.
There can be no assurance that, in the future,  software  defects will not cause
delays in  product  introductions  and  shipments,  result in  increased  costs,
require design modifications, or impair customer satisfaction with the Company's
products.  Any such event could have a material  adverse effect on the Company's
business, operating results and financial conditions.

COMPETITION

         The  market  for the  Company's  products  and  services  is  intensely
competitive and subject to rapid change caused by new product  introductions and
other  market  activities  of  industry  participants.   The  Company  currently
encounters  direct and indirect  competition from a number of public and private
companies  involved  in  groupware,   document  management,   and  collaboration
software,  including Xerox, Open Text, Net-It Software,  Hummingbird and Fulcrum
Technologies.  The Company is aware that other companies have announced products
with some features similar to VFC. In addition, the Company may face competition
from new market  entrants.  Competitors  may have  longer  operating  histories,
significantly  greater financial,  marketing,  service,  support,  technical and
other resources and name recognition and a larger  installed  customer base than
the Company.  As a result,  such competitors may be able to respond more quickly
to new or  emerging  technologies  and changes in  customer  requirements  or to
devote  greater  resources  to the  development,  promotion  and  sale of  their
products than the Company.

         The Company also faces indirect  competition  from system  integrators.
The Company relies on a number of system  integration  firms for  implementation
and other services,  as well as for  recommendations  of its products during the
evaluation  stage of the  purchasing  process.  Although  the  Company  seeks to
maintain close  relationships with these service providers,  many of these third
parties have similar, and often more established, relationships with some of the
Company's  competitors.  It is also possible that new  competitors  or alliances
among  competitors may emerge and rapidly acquire  significant  market share. In
addition,  the Company  expects  competition to increase as a result of software
industry consolidation.

         The Company believes that the competitive  factors affecting the market
for its products and services include vendor and product reputation,  ability to
attract and retain quality  personnel,  product quality,  performance and price,
the availability of products on multiple platforms, product salability,  product
integration  with  other  enterprise  applications,  product  functionality  and
features, product ease-of-use,  and the quality of customer support services and
training.  The relative  importance  of each of these  factors  depends upon the
specific customer involved.  While the Company believes it competes favorably in
each of these areas,  there can be no assurance  that it will continue 


                                     - 32 -

<PAGE>

to do so. Moreover,  the Company's present or future  competitors may be able to
develop products  comparable or superior to those offered by the Company,  offer
lower priced products or adapt more quickly than the Company to new technologies
or evolving customer requirements.  In order to be successful,  the Company must
respond to technological change,  customer requirements and competitors' current
products and  innovations.  There can be no  assurance  that the Company will be
able to compete  effectively in its market or that  competition  will not have a
material  adverse  effect  on its  business,  operating  results  and  financial
condition.

PROPRIETARY RIGHTS

         The Company has registered  copyrights,  trademarks and servicemarks to
protect its proprietary  rights in the names Infodata and INQUIRE.  In addition,
the Company has submitted  trademark  applications  in order to protect its VFC,
WebINQUIRE, Aerial, Compose and Re:mark names.

         The  Company  relies  primarily  on a  combination  of  copyrights  and
trademarks, trade secrets, confidentiality procedures and contractual provisions
to protect its proprietary rights. For example, the Company licenses rather than
sells its software.  The licenses impose certain  restrictions on the licensees'
ability to  utilize  the  software.  In  addition,  the  Company  seeks to avoid
disclosure of its trade  secrets,  including,  but not limited to, (i) requiring
those persons with access to the Company's  proprietary  information  to execute
confidentiality  agreements with the Company and (ii) restricting  access to the
Company's  source  codes.  Trade secret and  copyright  laws afford only limited
protection.  Despite the Company's  efforts to protect its  proprietary  rights,
unauthorized parties may attempt to copy the Company's products or to obtain and
use information  that the Company  regards as proprietary.  Although the Company
may apply for certain design  patents,  the Company  presently has no patents or
patent applications pending. Policing unauthorized use of the Company's products
is  difficult,  and while the Company may be unable to  determine  the extent to
which piracy of its software products exists, software piracy can be expected to
be a persistent problem. In addition,  the laws of some foreign countries do not
protect the  Company's  proprietary  rights to as great an extent as the laws of
the  United  States.  There  can be no  assurance  that the  Company's  means of
protecting  its  proprietary  rights  will be  adequate  or that  the  Company's
competitors will not develop similar technology  independently.  There can be no
assurance  that third  parties will not claim  infringement  by the Company with
respect to current or future  products.  The Company  expects  software  product
developers  increasingly to be subject to  infringement  claims as the number of
products  and  competitors  in the  Company's  industry  segment  grows  and the
functionality  of products in different  industry  segments  overlaps.  Any such
claims,  with or  without  merit,  could be  time-consuming,  result  in  costly
litigation,  cause product  shipment delays or require the Company to enter into
royalty or  licensing  agreements.  Such  royalty or  licensing  agreements,  if
required,  may not be  available on terms  acceptable  to the Company or at all,
which  could  have a  material  adverse  effect  upon  the  Company's  business,
operating results and financial condition.  In addition, the Company also relies
on certain software that it licenses from third parties, including software that
is  integrated  with  internally  developed  software and used in the  Company's
products to perform key  functions.  There can be no assurances  that such firms
will remain in business,  that they will continue to support  their  products or
that their  products will  otherwise  continue to be available to the Company on
commercially reasonable terms.

EMPLOYEES

         As of December 12, 1997, the Company had a total of 116  employees,  of
which 74 were  technical  professionals,  15  comprise  the sales and  marketing
staff,  and the  remainder  were  involved in  management,  administration,  and
accounting.

MANUFACTURING

         The  Company   contracts  for  the  manufacture  of  its  software  and
packaging.  The Company  believes that there are adequate  sources of supply and
manufacturing capacity to address the Company's requirements.

PROPERTY

         The Company leases  professional  office space for its headquarters and
operations in Fairfax, Virginia and recently expanded its space and extended the
term of its lease  through July 31,  2003,  pending  execution by the  


                                     - 33 -

landlord.  Leased space now totals 25,950 square feet.  Payments under the lease
were  approximately  $368,316 in 1997,  are expected to be $462,000 in 1998, and
will increase to $599,124 by 2003.

         The Company also maintains an office of approximately 3,400 square feet
in  Mountain  View,  California.  Payments  under the lease  were  approximately
$72,968 in 1997.  The lease  expires May 31, 1998 and the Company is  discussing
the possibility of extending the lease with the landlord.

LEGAL PROCEEDINGS

         The Company is presently not a party to any material legal proceedings.

(1)  The  value of  unexercised  in-the-money  options  at  fiscal  year end was
     calculated  by obtaining the product of the last sale price on December 31,
     1996 (which was $7.00 per share)  multiplied by the number of  in-the-money
     exercisable options or the number of in-the-money unexercisable options, as
     the case may be.


AGREEMENTS WITH EXECUTIVES

         The Company has entered into Executive  Separation  Agreements with Mr.
Kaplowitz  and Dr.  Loane.  In the event that  either  officer's  employment  is
terminated  involuntarily,  without cause,  following a change in control of the
Company,  as defined,  that officer is entitled to  separation  pay equal to two
years' base salary and  continuation of life and health  insurance  coverage for
two years. Additionally,  any type of pension or profit-sharing credited service
will be extended for two years.  There were no  separation  payments  accrued or
paid under the Executive Separation Agreements in 1996.

         As part of the acquisition of Merex by the Company in October 1995, the
Company  entered  into an  Employment  and  Non-Compete  Agreement  ("Employment
Agreement"), dated October 11, 1995, with Richard M.


                                     - 39 -


<PAGE>

Tworek. Pursuant to the Employment Agreement, Mr. Tworek is serving as Executive
Vice  President of the Company  until  October 11, 1999,  and receives a minimum
base  salary  of  $125,000  per  year,  plus any  bonus  compensation  as may be
determined by the Company's  Board of Directors.  The Employment  Agreement also
provides  that Mr.  Tworek may not  compete  with the Company for two years with
respect  to any then  existing  client,  customer  or  supplier  of the  Company
following  the  expiration or  termination  of the  Employment  Agreement or his
earlier resignation.

         The  Company  entered  into  a  letter  employment  agreement  ("Letter
Agreement") with James  Ungerleider on November 5, 1997.  Pursuant to the Letter
Agreement,  Mr.  Ungerleider  is serving as the  Company's  President  and Chief
Executive  Officer and receives an annual base salary of $200,000 plus an annual
incentive  bonus based on the achievement of certain  management  objectives and
financial performance measures. In addition, Mr. Ungerleider received options to
acquire  250,000  shares of the  Company's  Common Stock at a price of $9.50 per
share, vesting over a three year period from the date of the Letter Agreement, a
$50,000  hiring bonus to be paid on January 2, 1998,  health  insurance and life
insurance. Mr. Ungerleider's employment at the Company is terminable at will and
is not for a definite  term.  However,  if Mr.  Ungerleider is terminated by the
Company,  other than "for  cause," as defined in the Letter  Agreement,  he will
continue  to be paid his base  salary in monthly  increments  for a period of 18
months,  and he will continue to receive various insurance  benefits during such
period.  These insurance and salary  benefits will cease should Mr.  Ungerleider
begin employment  elsewhere with a new employer during such 18 month period. The
Letter Agreement also provides that, if during Mr. Ungerleider's first 12 months
of employment with the Company,  Mr. Bueschel is no longer Chairman of the Board
and during that same 12 month period Mr.  Ungerleider  is terminated  other than
for cause, the  aforementioned  salary and benefit provision will apply for a 24
month period.

         As part of the  acquisition of AMBIA,  on July 22, 1997 the Company and
AMBIA  entered  into  a  two-year  employment   agreement  with  Razi  Mohiuddin
("Mohiuddin  Employment  Agreement").   Pursuant  to  the  Mohiuddin  Employment
Agreement,  Mr.  Mohiuddin  is serving as a Vice  President  of the  Company and
manager of the Company's West Coast  facilities for a term of 24 months,  unless
extended by the mutual agreement of the Company and Mr.  Mohiuddin,  with a base
salary of $110,000 per year, subject to adjustment based on performance reviews.
The  Mohiuddin  Employment  Agreement  also  provides  that if Mr.  Mohiuddin is
terminated  for  cause,  Mr.  Mohiuddin  will  be  subject  to a  noncompetition
provision for a period of two years and a nonsolicitation provision for a period
of one year following the date of termination.

DIRECTOR COMPENSATION

         During 1996,  non-employee  directors  received an annual fee of $3,000
plus $500 per Board  meeting or meeting of a  committee  of the Board  (fees for
committee  meetings  held on the same day as Board  meetings  are $100).  During
1996,  no  Executive  Committee  meeting  fees were accrued or paid to Executive
Committee members.  During 1996, Laurence C. Glazer, Isaac M. Pollak and Millard
H.  Pryor,  Jr.,  members of the  Compensation  Committee,  were each  granted a
non-qualified  option  under the  Company's  1995 Stock  Option Plan to purchase
4,666 shares of Common Stock at an exercise  price of $5.0313 per share.  During
1997,  non-employee  directors  will receive an annual fee amounting to $10,000,
payable quarterly in shares of the Company's Common Stock, plus $1,000 per board
meeting  attended.  Any director  who is an employee of the Company  receives no
additional compensation for serving as a director.

1995 STOCK OPTION PLAN

         In 1995, the Board of Directors adopted, and the Company's shareholders
approved,  the 1995 Stock Option Plan ("1995 Plan"),  which (i) consolidated the
Company's 1991 Incentive Stock Option Plan and 1992  Non-Qualified  Stock Option
Plan and (ii) provided for the  automatic  grant of stock options to the members
of the Compensation Committee of the Company's Board of Directors ("Compensation
Committee").  The  purpose of the 1995 Plan is to attract,  retain and  motivate
directors,  officers, selected employees and consultants of the Company, as well
as officers and selected employees of any subsidiary  thereof, by affording them
an opportunity  to acquire a proprietary  interest in the Company and to thereby
create in such  persons an  increased  interest  and a greater  concern  for the
welfare  of the  Company.  The 1995  Plan is  administered  by the  Compensation
Committee, which consists of not less


                                     - 40 -


<PAGE>

than two  members  of the  Board  of  Directors  who  qualify  as  "non-employee
directors"  of the Company  within the meaning of Rule 16b-3 under the  Exchange
Act.

         Subject  to  possible  adjustment  in the event of a  recapitalization,
stock split or similar transaction,  a total of 1,511,000 shares of Common Stock
may be issued upon the exercise of options granted under the 1995 Plan.  Options
to purchase an aggregate of 1,439,381 shares of Common Stock under the 1995 Plan
have been issued in the past, of which options to purchase  287,234  shares have
been exercised and options to purchase  49,625 shares have either  terminated or
lapsed. As of December 12, 1997, options to purchase a total of 1,350,366 shares
of Common Stock under the 1995 Plan, at prices ranging from $1.085 to $11.00 per
share,  were  outstanding.  Of the currently  outstanding  options,  options for
620,114 shares are currently vested and exercisable. The 1995 Plan also provides
that if any  shares  underlying  outstanding  options  cease  to be  subject  to
purchase thereunder due to expiration or termination of the options, such shares
thereafter  will be available to underlie  newly granted  options under the 1995
Plan.

         The Compensation Committee may grant options under the 1995 Plan to (i)
certain selected employees and officers of the Company or any subsidiary thereof
who are regularly  employed on a salaried basis;  (ii) directors of the Company,
other than  members  of the  Compensation  Committee,  who are not  officers  or
employees  of the  Company;  and (iii)  consultants  or advisors to the Company,
provided that the services  rendered by such persons are not in connection  with
the offer or sale of securities in a capital-raising transaction. Members of the
Compensation Committee receive awards of options pursuant to a formula set forth
in the 1995 Plan.

         The  1995  Plan  provides   that  upon  the   occurrence  of  an  event
constituting  a "change of  control,"  all options  granted  under the 1995 Plan
immediately  become fully  exercisable.  A "change of control" will be deemed to
have  occurred  under the 1995 Plan if any person or  organization  becomes  the
beneficial  owner,  directly  or  indirectly,  of either (i) a  majority  of the
Company's  outstanding  shares of Common Stock or (ii) securities of the Company
representing  a majority of the  combined  voting  power of the  Company's  then
outstanding voting securities.

         As a result of the Company's acquisition of AMBIA,  outstanding options
to purchase  390,000  shares of AMBIA common stock were  converted  into options
("Replacement  Options") to acquire  approximately 35,000 shares of Common Stock
of the Company at an exercise price of $1.69 per share. The Replacement  Options
are  subject to the terms of the 1995  Plan.  The  Company  has agreed to file a
registration  statement  on Form  S-8 to  register  the  shares  underlying  the
Replacement Options by January 5, 1998.

STOCK PURCHASE PLAN

         On April 23, 1997,  the Board of Directors of the Company  approved the
adoption of the Company's 1997 Employee Stock Purchase Plan ("SPP"),  and on May
28,  1997,  the holders of a majority  of the  Company's  outstanding  shares of
Common Stock present or  represented at the Annual Meeting duly adopted the SPP.
The  purpose of the SPP is to provide  eligible  employees  the  opportunity  to
purchase  Common Stock  through  payroll  deductions.  The SPP is intended as an
employment  incentive and to encourage stock  ownership such that  participating
employees can share in the Company's progress.

         The SPP is administered  by the Board of Directors of the Company.  Any
employee of the Company is eligible to participate, on a voluntary basis, in the
SPP,  except  that  persons who own or hold stock,  including  stock  underlying
options,  or as a result of participation in the SPP would own stock,  including
stock underlying  options,  amounting to 5% or more of the total combined voting
power or value of all  classes  of stock  of the  Company  are not  entitled  to
participate  in the SPP.  Currently,  approximately  115 persons are eligible to
participate in the SPP.  200,000  shares of the  authorized but unissued  Common
Stock of the Company have been reserved for issuance under the SPP.

         The  purchase  price per share at which  shares of the Common Stock are
sold  in an  offering  under  the SPP is set by the  Board;  provided  that  the
purchase  price may not be less than 85% of the lesser of the fair market  value
of the Common Stock on the first or the last day of the offering period. Subject
to certain  limitations,  the number of shares of the Common Stock a participant
purchases in an offering period is determined by dividing the total


                                     - 41 -


<PAGE>

amount of payroll deductions withheld from the participant's compensation during
the offering period by the purchase price per share.

EMPLOYEE BENEFIT PLAN

         In 1988,  the Company  established  an employee  benefit plan ("Benefit
Plan"),  which  qualifies  under  Section  401(k) of the Code.  The Benefit Plan
allows  salaried  employees to  contribute a part of their  compensation  toward
their retirement on a tax deferred basis.  Required Company contributions equate
to  10%  of  the  employee's  contribution  to  the  Benefit  Plan  and  totaled
approximately  $32,000  in 1996  and  $23,000  in  1995.  In  addition  to these
contributions,  the Company,  at the sole  discretion of its Board of Directors,
may make profit-sharing contributions to the Benefit Plan; no such contributions
were made in 1996 or 1995.


                              CERTAIN TRANSACTIONS

         For the period beginning January 1, 1996 through November 30, 1997, the
Company made business  management  consulting fee payments  totaling $230,000 to
Bermuda  Capital for the  services of Mr.  Richard T.  Bueschel,  the  Company's
Chairman, for his services as acting Chief Executive Officer of the Company from
1996 to 1997.  The Company  does not have a written  consulting  agreement  with
Bermuda Capital or Mr. Bueschel.

         For the period beginning January 1, 1996 through November 30, 1997, the
Company made payments  totaling  $160,500 to Huguenot  Associates,  Inc. for the
consulting  services  of its  President,  Robert M.  Leopold,  a director of the
Company.  The  Company  is  currently  making  payments  of $7,500  per month to
Huguenot Associates,  Inc. for financial  consulting services.  In January 1996,
the Company  issued 8,000 shares of its Common Stock to Mr. Leopold for services
rendered by him to the Company in  connection  with the  acquisition  of certain
assets and liabilities of Merex on October 11, 1995.

         On October 3, 1996, the Company extended a loan to Richard M. Tworek, a
director  and  executive  officer of the  Company,  in the  principal  amount of
$70,000.  The loan bears annual  interest of prime plus 1% and is payable by him
on or before  October 2, 1999. As of the date of the  Prospectus,  the principal
amount of the loan was $70,000.

         In October 1995, the Company purchased  substantially all of the assets
and assumed certain  liabilities of Merex in  consideration  for the issuance of
210,000  shares of Common Stock to Richard M. Tworek,  Mary  Margaret  Styer and
Andrew M.  Fregly  (collectively,  "Merex  Shareholders"),  with a fair value as
determined by the Company's  Board of Directors of $1.125 per share.  158,754 of
such shares were issued to Richard M. Tworek. The purchase was effected pursuant
to an Asset  and  Purchase  Agreement  and Plan of  Reorganization,  dated as of
October 6, 1995  ("Merex  Agreement"),  among the  Company,  Merex and the Merex
Shareholders. Pursuant to the Merex Agreement, the Company agreed, until October
11, 1998, to register the shares issued to the Merex Shareholders within 30 days
of  their  written  request  to do so.  Mr.  Tworek  has  agreed  to  waive  his
registration rights for a period of six months following the Effective Date. The
total acquisition cost was approximately $361,000, including the direct costs of
the acquisition.  As part of the Merex  Agreement,  the Company entered into the
Employment Agreement with Mr. Tworek, pursuant to which Mr. Tworek is serving as
Executive  Vice  President of the Company until October 11, 1999, and receives a
minimum  base  salary  of  $125,000,  plus  any  bonus  compensation  as  may be
determined by the Company's Board of Directors.

                   On July 22, 1997, the Company acquired 100% of the issued and
outstanding  capital  stock of AMBIA  through the issuance of 400,000  shares of
Common  Stock  to  AMBIA's   shareholders,   Alan  Fisher  and  Razi   Mohiuddin
(collectively,  "AMBIA  Shareholders"),  with a fair value as  determined by the
Company's  Board of  Directors of $5.425 per share.  Pursuant to a  registration
rights  agreement  by and among the  Company  and the  AMBIA  Shareholders,  the
Company  granted the AMBIA  Shareholders a one-time demand  registration  right,
exercisable until July 22, 2000 at the request of both AMBIA  Shareholders.  The
agreement also entitles the AMBIA Shareholders to piggyback  registration rights
until  July 22,  2000.  The  AMBIA  Shareholders  have  agreed  to  waive  their
registration rights for a period of six months following the Effective Date. The
acquisition  was  accomplished  by  means  of  a  merger  of  AMBIA  Acquisition
Corporation, a Delaware corporation ("Acquisition") and wholly-


                                     - 42 -


<PAGE>

owned subsidiary of the Company,  with and into AMBIA,  pursuant to the terms of
the  Agreement of Merger and Plan of  Reorganization,  dated as of July 22, 1997
("AMBIA  Agreement"),  by and among the Company,  AMBIA, the AMBIA Shareholders,
Software Partners,  Inc., a Delaware corporation ("SPI"), and Acquisition.  As a
result of the  Merger,  all of the issued and  outstanding  shares of AMBIA were
exchanged for and converted into 400,000  shares of the Company's  Common Stock,
339,999  shares were  delivered to the AMBIA  Shareholders,  60,000  shares were
delivered  to an  escrow  agent  and  one  share  was  delivered  to  the  AMBIA
Shareholders  in cash in  lieu  of a  fractional  share.  The  escrow  is  being
maintained to secure the Company against breaches of representations, warranties
and covenants made under the AMBIA Agreement by the AMBIA Shareholders,  SPI and
AMBIA. The total  acquisition cost was approximately  $2,300,000,  including the
direct costs of the  acquisition.  As a part of the  acquisition  of AMBIA,  the
Company  and  AMBIA  entered  into a  two-year  employment  agreement  with  Mr.
Mohiuddin, pursuant to which Mr. Mohiuddin is serving as a Vice President of the
Company and manager of the Company's  West Coast  facilities at a base salary of
$110,000 per year. In addition, as part of the acquisition of AMBIA, the Company
agreed to  appoint  Alan  Fisher to its Board of  Directors,  subject to certain
provisions in the AMBIA Agreement.

                            DESCRIPTION OF SECURITIES

GENERAL

         The  authorized  capital  stock of the  Company  is  7,006,666  shares,
consisting of 6,666,666  shares of Common Stock,  par value $0.03 per share, and
340,000 shares of Preferred Stock, par value $1.00 per share. As of December 12,
1997,  there were  2,749,791  shares of Common Stock  outstanding.  No shares of
Preferred  Stock are currently  outstanding.  Upon  completion of this Offering,
there  will be  approximately  3,749,791  shares  of  Common  Stock  outstanding
(3,899,791 if the Underwriters'  over-allotment option is exercised in full) and
no shares of Preferred Stock outstanding.


COMMON STOCK

         The holders of shares of Common Stock are entitled to one vote for each
share held of record on all matters to be voted on by shareholders.  There is no
cumulative  voting with  respect to the election of  directors,  with the result
that the  holders  of more  than 50% of the  shares  voted  can elect all of the
directors  then being  elected.  The  holders of Common  Stock are  entitled  to
receive  dividends  when,  as and if declared by the Board of  Directors  out of
funds legally available  therefor.  In the event of liquidation,  dissolution or
winding up of the  Company,  the holders of Common  Stock are  entitled to share
ratably in all assets remaining available for distribution to them after payment
of  liabilities  and after  provision has been made for each class of stock,  if
any, having preference over the Common Stock. Holders of shares of Common Stock,
as such, have no redemption,  preemptive or other subscription rights, and there
are  no  conversion  provisions  applicable  to  the  Common  Stock.  All of the
outstanding  shares of Common Stock are, and the shares of Common Stock  offered
hereby, when issued and paid for as set forth in this Prospectus, will be, fully
paid and nonassessable.

PREFERRED STOCK

         The Company's authorized shares of Preferred Stock may be issued in one
or more series. The Board of Directors is expressly vested with the authority to
fix  by  resolution  the  designations,  powers,  preferences,   qualifications,
limitations  or  restrictions  of and upon  shares  of each  series,  including,
without limitation,  voting,  dividend,  conversion,  redemption and liquidation
rights.  In  addition,  the  Board of  Directors  may fix the  number  of shares
constituting  any such series and  increase or decrease  the number of shares in
any such series.

          The Company believes that the availability of Preferred Stock issuable
in series will provide  increased  flexibility for  structuring  possible future
financings and acquisitions, if any, and in meeting other corporate needs. It is
not possible to state the actual effect of the authorization and issuance of any
series of  Preferred  Stock upon the rights of holders of Common Stock until the
Board of Directors  determines the specific  terms,  rights and preferences of a
series of Preferred  Stock.  However,  such effects might  include,  among other
things,  restricting dividends on the Common Stock, diluting the voting power of
the Common Stock, or impairing liquidation rights of such shares without further
action by holders of the Common Stock. In addition, under various circumstances,
the issuance of Preferred Stock may have the effect of facilitating,  as well as
impeding or discouraging,  a merger, tender offer, proxy contest, the assumption
of  control  by a holder of a large  block of the  Company's  securities  or the
removal of incumbent  management.  The  issuance of  Preferred  Stock could also
adversely affect the market price of the Common Stock.

LIMITATION OF LIABILITY OF OFFICERS AND DIRECTORS

         As permitted by the  Virginia  Stock  Corporations  Act  ("VSCA"),  the
Company's  Articles  and Bylaws  limit the  personal  liability of a director or
officer to the Company for monetary damages for breach of fiduciary duty of care
as a director. Liability is not eliminated if the officer or director engaged in
willful  misconduct or a knowing violation of the criminal law or of any federal
or state securities law, including,  without  limitation,  any claim of unlawful
insider trading or manipulation of the market for any security.  Furthermore,  a
director who votes for or


                                     - 45 -


<PAGE>

assents to distributions made in violation of the VSCA or the Company's Articles
will be personally liable to the Company and its creditors for the amount of the
distribution that exceeds what could have been distributed without violating the
VSCA or the Company's Articles, pursuant to Section 13.1-692 of the VSCA.

INDEMNIFICATION OF OFFICERS AND DIRECTORS

         The Company's  Articles and Bylaws require the Company to indemnify any
director or officer of the  Company,  or any person who is or was serving at the
request  of the  Company  as a  director  or  officer  of  another  corporation,
partnership,  joint venture,  trust or other  enterprise,  to the fullest extent
permitted by law. The Company has obtained  officers' and  directors'  liability
insurance  of  $1,000,000  for members of its Board of Directors  and  executive
officers.  In addition to the indemnification  provided in the Company's Bylaws,
the Company  intends to enter into  agreements  to indemnify  its  directors and
officers.

         Insofar as indemnification for liabilities arising under the Securities
Act, as amended, may be permitted to directors,  officers or persons controlling
the Company pursuant to the foregoing provisions,  or otherwise, the Company has
been  informed that in the opinion of the  Commission  such  indemnification  is
against  public  policy as  expressed  in the  Securities  Act and is  therefore
unenforceable.

VIRGINIA ANTI-TAKEOVER LAW AND CERTAIN CHARTER AND BYLAW PROVISIONS

         The Company is subject to the  provisions of Section  13.1-725.1 of the
VSCA.  Subject  to  certain  exceptions,  these  provisions  apply  to  Virginia
corporations  having more than 300  shareholders  of record and provide that for
three years following the time that a shareholder becomes an owner of 10% of the
outstanding voting shares (an "Interested Shareholder"),  a Virginia corporation
cannot engage in any "Affiliated  Transaction" with such Interested  Shareholder
without the approval of  two-thirds of the voting shares other than those shares
beneficially owned by the Interested Shareholder, and the approval of a majority
of the  disinterested  directors  (as defined in Section  13.1-725 of the VSCA).
After the expiration of the three-year period, the statute requires,  subject to
certain  exceptions,  approval of Affiliated  Transactions  by two-thirds of the
voting shares other than those beneficially owned by the Interested Shareholder.
Affiliated  Transactions  subject to this approval  requirement include mergers,
share exchanges,  material  dispositions of corporate assets not in the ordinary
course of business,  any guarantee by the  corporation  of a material  amount of
indebtedness  of  any  Interested   Shareholder,   certain  dispositions  to  an
Interested  Shareholder of voting shares of the corporation,  any dissolution of
the corporation  proposed by or on behalf of an Interested  Shareholder,  or any
reclassification,  including reverse stock splits, recapitalization or merger of
the corporation with its subsidiaries,  which increases the percentage of voting
shares owned beneficially by an Interested Shareholder by more than 5%. Virginia
law also provides that, with respect to Virginia corporations having 300 or more
shareholders of record,  shares acquired in a transaction  that would cause such
holder's voting strength to meet or exceed any of three thresholds (20%, 33 1/3%
or 50%) have no voting  rights with respect to such shares  unless  granted by a
majority  vote of shares  not owned by the  acquiring  person or any  officer or
employee-director  of the  corporation.  This provision  empowers such holder to
require the Virginia  corporation to hold a special  meeting of  shareholders to
consider the matter within 50 days of its request.

         Article  3 of  the  Company's  Articles  provides  that  the  Board  of
Directors, without action by the shareholders,  may issue and fix the rights and
preferences  of shares of Preferred  Stock.  Article 2 of the  Company's  Bylaws
further  provides that a director may only be removed upon the affirmative  vote
of a majority  of the voting  power of the  shareholders  of record  entitled to
elect a successor and present in person or by proxy at a special meeting of such
shareholders for which express notice of the intention to transact such business
was given and at which a quorum is present. These provisions may have the effect
of delaying,  deferring or preventing a change of control of the Company without
further action by the shareholders,  may discourage bids for the Common Stock at
a premium  over the market  price of,  and the  voting  and other  rights of the
holders of, Common Stock.

          The  provisions  of Virginia law and the  provisions  contained in the
Company's Articles and Bylaws,  discussed above, could prohibit or delay mergers
or other takeover or change in control attempts with respect to the Company and,
accordingly, may discourage attempts to acquire the Company.

         The transfer agent and registrar for the Common Stock is American Stock

agreements.  Additionally,  as of the date of this  Prospectus,  the Company has
reserved an  aggregate of  1,646,000  shares of Common  Stock for issuance  upon
exercise of outstanding  options and the  Representatives'  Purchase Option. All
but 635,000 of the shares of Common Stock  underlying  such securities have been
registered under the Securities Act.

         Pursuant to the asset  purchase  agreement by and among the Company and
the Merex Shareholders,  the Company agreed, until October 11, 1998, to register
the 210,000 shares issued to the Merex Shareholders,  158,754 of which have been
issued to Richard M. Tworek,  within 30 days of their written  request to do so.
Mr.  Tworek  has  agreed to waive his  registration  rights  for a period of six
months following the Effective Date.

         Pursuant to a  registration  rights  agreement by and among the Company
and the AMBIA  Shareholders,  executed in  connection  with the  acquisition  of
AMBIA, the Company granted the AMBIA Shareholders a one-time demand registration
right with  respect to the  400,000  shares  (including  60,000  held in escrow)
issued to them. The demand registration right is exercisable until July 22, 2000
at the request of both Razi Mohiuddin and Alan Fisher.  The registration  rights
agreement also provides,  subject to certain exceptions, for unlimited piggyback
registration  rights until July 22, 2000. The AMBIA  Shareholders have agreed to
waive their   registration  rights for a period of six months following the
Effective  Date.


                                  UNDERWRITING

         The Underwriters  named herein,  for whom Southeast  Research Partners,

          Total                                                    1,000,000
                                                            ================



         The  Underwriting  Agreement  provides  that  the  obligations  of  the
Underwriters  are subject to approval of certain legal matters by counsel to the
Underwriters and various other conditions  precedent,  and that the Underwriters
are obligated to purchase all the shares of Common Stock  offered  hereby (other
than the shares of Common Stock covered by the  over-allotment  option described
below) if any are purchased.

         The  Representatives  have  advised the Company  that the  Underwriters
propose to offer the shares of Common Stock to the public at the price set forth
on the cover page of this Prospectus and to certain dealers at those prices less
a concession not in excess of $ per share.  The Underwriters may allow, and such
dealers may reallow,  a concession not in excess of $ per share to certain other
dealers.  After the Offering, the offering prices and other terms may be changed
by the Representatives.

         The  Company  has granted to the  Underwriters  an option,  exercisable
during the 45-day period after the date of this Prospectus, to purchase from the
Company at the  offering  price set forth on the cover page of this  Prospectus,
less  underwriting  discounts and  commissions,  up to 150,000  shares of Common
Stock.

         The Company has agreed to indemnify the  Underwriters  against  certain
liabilities,  including  liabilities  under the Securities Act. The Company also
has agreed to pay the  Representatives  an expense allowance on a nonaccountable
basis equal to 2% of the gross  proceeds  derived from the sale of the shares of
Common  Stock  underwritten  (including  the sale of any shares of Common  Stock
subject to the Underwriters'  over-allotment option),  $50,000 of which has been
paid to date.

         In connection with the Offering,  the Company has agreed to sell to the
Representatives,  for an  aggregate  of $100,  an  option to  purchase  up to an
aggregate  of  100,000  shares  of  Common  Stock  ("Representatives'   Purchase
Option").  The  Representatives'  Purchase  Option is exercisable at $ per share
(120% of the offering price) for a period of four years commencing one year from
the date of this Prospectus.  The Representatives' Purchase Option grants to the
holders thereof  certain  "piggyback" and demand rights for periods of seven and
five years,  respectively,  from the date of this Prospectus with respect to the
registration  under the Securities  Act of the shares  issuable upon exercise of
the  Representatives'  Purchase  Option.  The  Representatives'  Purchase Option
cannot be transferred, sold, assigned or hypothecated during the one year period
following the date of this Prospectus, except to officers of the Representatives
and to Underwriters and selected dealers and their officers or partners.

         Pursuant to the  Underwriting  Agreement,  the  directors and executive
officers  and certain  shareholders  of the Company  (collectively,  "Insiders")
holding,  in the  aggregate,  962,510  shares of Common  Stock  and  options  to
purchase an aggregate of 730,526 shares of Common Stock, have agreed not to sell
or otherwise  dispose of any of such shares for a period of 12 months  following
the Effective Date without  obtaining the prior written consent of GKN; provided
however, that (a) at any time beginning six months after the Effective Date each
of the Insiders may sell,  without GKN's consent,  up to 20% of the shares owned
by him, if (i) the last sales  price of the Common  Stock has been at least 125%
of the per share public offering price for at least 10 consecutive  trading days
ending the day prior to the proposed sale and (ii) the sales price of the shares
to be sold is no less than 125% of the per share public offering  price,  (b) at
any time  beginning  three  months  after the  Effective  Date,  (i)  Richard T.
Bueschel may sell up to an aggregate of 7,500 shares,  (ii) Harry  Kaplowitz may
sell up to an aggregate of 12,500 shares,  (iii) Dr. Robert J. Loane may sell up
to an  aggregate  of 2,500  shares and (iv) Robert M.  Leopold may sell up to an
aggregate of 7,500 shares,  in each case without GKN's  consent,  and (c) at any
time after the Effective Date,  Richard M. Tworek may sell up to an aggregate of
15,000 shares without GKN's consent.  GKN may, in its sole discretion and at any
time without  notice,  release all or any portion of the  securities  subject to
lock-up agreements.

         The   Underwriters   may   engage   in   over-allotment,    stabilizing
transactions,   syndicate  short  covering  transactions  and  penalty  bids  in
accordance  with  Regulation M under the Exchange Act.  Over-allotment  involves
sales by the  underwriting  syndicate  in excess  of the  offering  size,  which
creates a syndicate  short  position.  Stabilizing  transactions  permit bids to
purchase  the  shares of  Common  Stock so long as the  stabilizing  bids do not
exceed a  specified  maximum.  Syndicate  short  covering  transactions  involve
purchases  of  the  shares  of  Common  Stock  in  the  open  market  after  the
distribution  has been completed in order to cover  syndicate  short  positions.
Penalty  bids permit the  Underwriters  to reclaim a selling  concession  from a
selling  group  member when the shares of Common Stock  originally  sold by such
selling  group member are  repurchased  in the open market by the  Underwriters.
Such stabilizing transactions, syndicate short covering transactions and penalty
bids may  cause the price of the  shares  of Common  Stock to be higher  than it
would otherwise be in the absence of such  transactions.  These transactions may
be effected on the Nasdaq SmallCap Market or otherwise and, if commenced, may be
discontinued at any time.

         In general,  the rules of the Commission will prohibit the Underwriters
from making a market in the Common Stock during a "restricted period" commencing
up to five days prior to the  pricing of the  offering of Common  Stock  offered
hereby and  extending  until  completion of the Offering.  The  Commission  has,
however,  adopted  exceptions from these rules that permit passive market making
under certain conditions.  These rules permit an underwriter to continue to make
a market subject to the  conditions,  among others,  that its bid not exceed the
highest bid by a market maker not  connected  with the Offering and that its net
purchases on any one trading day not exceed prescribed limits. Pursuant to these
exemptions, the Underwriters, selling group members (if any) or their respective

                    Report of Independent Public Accountants

To Infodata Systems Inc.:

We have audited the accompanying consolidated balance sheets of Infodata Systems
Inc. (a Virginia corporation) and subsidiaries as of December 31, 1995 and 1996,
and the related consolidated statements of operations, changes in shareholders'
equity, and cash flows for the years then ended. These financial statements are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audits.

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

As discussed in Note 1, the Company has incurred accumulated and working capital
deficits. While the Company has developed a plan to obtain additional financing
to mitigate its liquidity risk, there can be no assurance that such funds will
be secured.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Infodata Systems Inc. and
subsidiaries as of December 31, 1995 and 1996, and the results of its operations
and its cash flows for the years then ended in conformity with generally
accepted accounting principles.

                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
                    (INFORMATION AS OF SEPTEMBER 30, 1997 AND
       FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1996 AND 1997 IS UNAUDITED)

1. ORGANIZATION AND OPERATIONS:

THE COMPANY

Infodata Systems Inc. (the "Company" or "Infodata") provides electronic document
systems to corporate and government workgroups, departments and enterprises.
Prior to 1994, substantially all of the Company's business was derived from the
sale, support and maintenance of INQUIRE/Text, which was the leading independent
full-text retrieval product in the IBM and IBM-compatible mainframe market. In
1994, the Company shifted its focus to providing a broader range of document and
information management solutions deliverable through client/server and intranet
technology. The Company created the Virtual File Cabinet ("VFC") to address
these markets in the current electronic document management systems landscape.
The Company provides consulting services, third party software products, its own
software products, maintenance and integration services to both corporate and
government customers.

The Company's operations are subject to certain risks and uncertainties,
including uncertainty of future operating results, fluctuations in quarterly
results, change in mix of products, decline in INQUIRE/Text sales and reliance
on VFC, lengthy sales and implementation cycles, rapid technological changes and
product obsolescence, competition, risks associated with sales channels, and
dependence on government contracts and security clearances. As of September 30,
1997, the Company had incurred a net loss and accumulated and working capital
deficits. Management has developed a plan to obtain additional financing to
mitigate the Company's liquidity risk through a public offering and sale of
1,000,000 shares of common stock pursuant to a registration statement to be
filed in December 1997 with the Securities and Exchange Commission ("SEC").
However, there can be no assurance that such funds will be secured. The lack of
such funds could have a material adverse impact on the Company's financial
condition.

BASIS OF PRESENTATION

The accompanying consolidated financial statements include the accounts of
Infodata and its wholly-owned subsidiaries, Infodata Systems International Inc.
and Infodata Research and Development Corporation. These entities are
collectively referred to herein as the "Company". All significant intercompany
accounts and transactions have been eliminated in consolidation.

2. ACQUISITION:

On July 22, 1997, the Company acquired all of the common stock of AMBIA
Corporation ("AMBIA") in consideration for 400,000 shares of the Company's
common stock (restricted as to sale) with a fair value as determined by the
Company's Board of Directors of $5.425 per share. The total acquisition cost was
approximately $2,300,000 including the direct costs of the acquisition.
Approximately $25,000 was allocated to acquired tangible assets, $60,000 to
acquired intangible assets, and $2,213,000 to goodwill. The acquisition was
treated as a purchase and was accomplished by means of a merger of a
wholly-owned subsidiary of the Company into AMBIA. AMBIA develops, markets and
sells software products and consulting services, which are complementary to
those being developed, marketed and sold by the Company.

The unaudited pro forma financial information presented below reflects the
acquisition of AMBIA as if the acquisition had occurred on January 1, 1996.
These results are not necessarily indicative of future operating results or of
what would have occurred had the acquisition been consummated at that time.

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

INTERIM REPORTING

The financial information as of September 30, 1997, and for the nine months
ended September 30, 1996 and 1997, has been prepared by the Company, without
audit, and includes, in the opinion of management, all adjustments, consisting
of normal recurring adjustments, necessary for a fair presentation of the
interim period results. Operating results for any interim period are not
necessarily indicative of the results for any other period or for an entire
year.


                                      F-8
<PAGE>

REVENUE RECOGNITION

The Company recognizes revenue from software licenses upon delivery of the
software product to the customer or upon customer acceptance if a trial period
exists. Revenues from post contract support, including revenue bundled with the
initial license fee, are recognized ratably over the period that customer
support services are provided. Software service revenue is recognized as
performed.

Revenues from consulting and professional services contracts are recognized on
the percentage-of-completion method for fixed price contracts and on the basis
of hours incurred at contract rates for time and materials contracts. Revenues
from cost reimbursement contracts are recognized as costs are incurred.

The American Institute of Certified Public Accountants has issued Statement of
Position ("SOP") 97-2, Software Revenue Recognition, that supersedes SOP 91-1.
SOP 97-2 provides additional guidance with respect to multiple elements,
returns, exchanges, and platform transfer rights; resellers; services; funded
software-development arrangements; and contract accounting. SOP 97-2 is to be
implemented for fiscal years beginning after December 15, 1997. The Company
believes that the adoption of SOP 97-2 will not have a material impact on the
Company's financial statements.

CASH EQUIVALENTS AND SHORT TERM INVESTMENTS

All highly liquid investments with an original maturity of 90 days or less at
the time of purchase are considered to be cash equivalents. At December 31, 1995
and 1996, and September 30, 1997, the Company had $1,269,000, $768,000 and $0,
respectively, of cash equivalents invested in commercial paper. 

Short term investments include certificates of deposit and securities available
for sale. Securities available for sale at December 31, 1995 and 1996, and
September 30, 1997, totaled approximately $0, $943,000 and $425,000,
respectively. At December 31, 1995 and 1996, the securities available for sale
consisted of commercial paper and U.S. Treasury Bills with maturities greater
than 90 days for which the carrying value approximated market value. 

At September 30, 1997, the securities available for sale consisted of U.S.
Treasury Bills. Available for sale securities are carried at fair value, with
unrealized gains and losses reported as a separate component of shareholders'
equity. No unrealized gains or losses were recorded for the years ended December
31, 1995 and 1996, nor for the nine month period ended September 30, 1997.
Realized gains and losses and declines in value judged to be other than
temporary on available for sale securities are included in other income.

SUPPLEMENTAL DISCLOSURES OF CASH FLOW INFORMATION

Cash payments for interest totaled $22,000 and $11,000 for the years ended
December 31, 1995 and 1996, respectively. Cash payments for interest totaled
$9,000 and $18,000 for the nine months ended September 30, 1996 and 1997,
respectively. Cash payments for income taxes totaled $7,000 and $4,000 for the
years ended December 31, 1995 and 1996, 


                                      F-9
<PAGE>

respectively. The Company did not make any cash payments for income taxes during
the nine month periods ended September 30, 1996 and 1997.

PROPERTY AND EQUIPMENT

Property and equipment is depreciated using the straight-line method. Computers
and related equipment are depreciated over three years and furniture and
equipment are depreciated over five to six years. Leasehold improvements are
amortized over the shorter of the useful life of the asset or the lease term.

GOODWILL

Goodwill created by the Merex, Inc. acquisition is amortized using the
straight-line method over ten years. Goodwill created by the AMBIA acquisition
is amortized using the straight-line method over seven years. The amount of
goodwill impairment, if any, would be measured based on the projected discounted
cash flows using a discount rate reflecting the Company's average cost of funds.
As of September 30, 1997, the Company does not believe there has been an
impairment of goodwill.

RESEARCH AND DEVELOPMENT

Research and development costs are expensed as incurred.

NET INCOME PER COMMON SHARE

For the years ended December 31, 1995 and 1996, the weighted average number of
common shares used in the calculation of primary net income per share was
approximately 1,694,000 and 2,162,000, respectively. On a fully diluted basis
for December 31, 1995 and 1996, the weighted average number of common and common
equivalent shares was approximately 1,465,000 and 2,718,000, respectively. The
weighted average number of common shares used in calculation of primary net
income per share was 2,796,000 for the nine months ended September 30, 1997. Due
to the anti-dilutive impact of common equivalent shares on net loss per share
for the nine month period ended September 30, 1997, common equivalent shares are
excluded from the weighted average number of shares on a fully diluted basis.

Net income for the years ended December 31, 1995 and 1996, and the nine months
ended September 30, 1996, have been decreased for preferred stock dividends of
$120,000, $58,000 and $58,000, respectively, to arrive at net income available
to common shareholders. The Company's preferred stock was converted into common
stock during 1996, thus no preferred stock dividends were declared in 1997 (see
Note 7).

SUPPLEMENTAL PRO FORMA NET LOSS PER SHARE

The Company anticipates repaying approximately $1 million in certain notes
payable with proceeds from the offering contemplated by a registration statement
to be filed in December 1997, with the SEC (See Note 1). Assuming such
repayment, supplemental pro forma net loss per share, adjusted to give effect
for the elimination of interest associated with such debt, would have been
$(.85)


                                      F-10
<PAGE>

for the nine month period ended September 30, 1997. For purposes of this
supplemental pro forma presentation, weighted average shares outstanding have
been adjusted for the estimated number of shares that the Company would need to
issue to repay the note payable discussed above, using the midpoint of the
anticipated offering range.

SIGNIFICANT CUSTOMERS

Sales to U.S. government agencies totaled approximately $2,586,000 and
$4,255,000 for the years ended December 31, 1995 and 1996, respectively,
representing 37% and 45% of revenues. As of December 31, 1995 and 1996, accounts
receivable due from U. S. government agencies approximated $678,000 and
$655,000, respectively. Sales to U.S. government agencies totaled approximately
$2,901,000 and $2,773,000 for the nine months ended September 30, 1996 and 1997,
respectively, representing 39% of revenues for each of the years then ended. At
September 30, 1997, accounts receivable from U.S. government agencies
approximated $568,000.

SOFTWARE DEVELOPMENT COSTS

Capitalization of software development costs begins upon the establishment of
technological feasibility. Capitalization ceases when the products are available
for general release to customers. The establishment of technological feasibility
and the continuing assessment of recoverability of capitalized software
development costs require considerable judgment by management with respect to
certain external factors, including, but not limited to, anticipated future
gross revenue, estimated economic life and changes in software and hardware
technologies. Amortization expense is determined on an individual product basis
and is computed as the greater of the amount calculated on a revenue basis or
straight-line basis over the economic life of the product, generally three to
five years. Amortization of software development costs is included in cost of
revenue in the accompanying consolidated statements of operations.

Periodically, the Company reviews the estimated lives and amounts assigned to
software development costs. In light of changing technology, the Company makes
revisions to estimated lives and adjusts amounts assigned as appropriate. On
December 31, 1995, the Company extended the remaining amortization period to
expire in 1998 to reflect the continued life of the INQUIRE product as reflected
by the substantial revenue stream associated with maintenance renewals. The
impact of such revision in estimated remaining useful life increased net income
by approximately $22,000 in 1996.

RECENT AUTHORITATIVE PRONOUNCEMENTS

Statement of Financial Accounting Standards ("SFAS") No. 128, "Earnings per
Share", changes the reporting requirements for earnings per share ("EPS") for
publicly-traded companies by replacing primary EPS with basic EPS and changing
the disclosures associated with this change. The Company is required to adopt
this standard for its December 31, 1997 year-end. The Company does not expect
that this pronouncement will have a material impact on its financial statements.


                                      F-11
<PAGE>

SFAS No. 129, "Disclosure of Information about Capital Structure," establishes
standards for disclosing information about an entity's capital structure. The
Company is required to adopt this standard for its December 31, 1997 year-end.
The Company does not expect that this pronouncement will have a material impact
on its financial statements.

SFAS No. 130, "Reporting Comprehensive Income," establishes standards for the
reporting and display of comprehensive income in a full set of general purpose
financial statements. The Company is required to adopt this standard for its
December 31, 1998 year-end and is currently evaluating the impact of the
standard.

SFAS No. 131, "Disclosures about Segments of an Enterprise and Related
Information," requires that public business enterprises report certain
information about operating segments. The Company is required to adopt this
standard for its December 31, 1998 year-end and is currently evaluating the
impact of the standard.

4. INCOME TAXES:

At December 31, 1996 and September 30, 1997, the Company had approximately
$5,347,000 and $7,643,000, respectively, in net operating loss carryforwards for
income tax reporting purposes.  The operating loss carryforwards expire in
varying amounts from 1998 through 2012. The acquisition of AMBIA during 1997
(see Note 2) could limit the extent to which the Company may utilize these
carryforwards in any one year. In addition, at December 31, 1996 and September
30, 1997, the Company had $70,000 in research and development tax credit
carryforwards expiring in 1997 and $55,000 in investment tax credit
carryforwards expiring in 1997 through 2000.

The actual income tax expense for the years ended December 31, 1995 and 1996,
differed from the amount computed by applying the Federal statutory rate of 34
percent as a result of the following:

                                        Year Ended    Year Ended    Nine Months

fully reserved due to the uncertainty of future taxable income. The
carryforwards will be benefited for financial reporting purposes when utilized
to offset future taxable income.

5. DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS:

Financial instruments are defined as cash, evidence of an ownership interest in
an entity or a contract that imposes an obligation to deliver cash or other
financial instruments to a second party. The carrying amounts of current assets
and current liabilities approximate fair value due to the short maturity of
these instruments.

6. NOTE PAYABLE:

In November 1996, the Company entered into a working capital line of credit with
Merrill Lynch Business Financial Services Inc. This loan facility provides the
Company with up to a $1,000,000 line of credit at a per annum rate equal to the
sum of 2.9 percent plus the 30 day commercial paper rate. This per annum rate
was 8.4% as of September 30, 1997. The weighted average interest rate for the
nine months ended September 30, 1997 was 8.4%. The advances on the facility are
based on eligible billed accounts receivable fewer than 90 days old, which
constitute collateral for the line of credit. The facility expires on December
31, 1997. As of December 31, 1996, the Company had no 


                                      F-13

borrowings under this line of credit. As of September 30, 1997, the Company had
borrowed $958,000 under this line of credit.

7. SHAREHOLDERS' EQUITY:

PREFERRED STOCK

During 1996, all the outstanding shares of preferred stock were converted into
common stock, and all dividends in arrears were satisfied through the issuance
of an equivalent number of common shares.

At December 31, 1995, 131,500 shares of convertible preferred stock were
outstanding. The preferred shares had the following provisions:

o     Cumulative, preferential dividends paid quarterly if declared by the Board
      of Directors at an annual rate of 9 percent ($.90 per share).

o     The option to convert one share of preferred stock for 1.111 common
      shares.

o     Full voting rights, to the extent of common shares that would be held upon
      conversion.

o     Pre-emptive rights relating to future stock offerings.

o     Preference in the distribution of corporate assets up to $10.00 per share
      plus cumulative unpaid dividends.

o     All the preferred stock was redeemable at the option of the Company at a
      price of $10.00 per share.

Dividends on preferred stock were paid upon declaration by the Board of
Directors. Cash dividends of $120,000 ($0.90 per preferred share) and $58,000
($0.45 per preferred share) were declared during 1995 and 1996, respectively.

OPTIONS AND WARRANTS

In April 1995, the Company's shareholders approved the adoption of the 1995
Stock Option Plan (the "1995 Plan") which consolidates and is the successor to
the Company's Incentive Stock Option Plan approved by shareholders in 1991 and
the Non-Qualified Stock Option Plan approved in 1992 (together, the "Predecessor
Plans"). Options have been granted to employees as well as to members of the
Board of Directors. The 1995 Plan also provides for the automatic granting of a
fixed number of options each year to members of the Compensation Committee of
the Company's Board of Directors and increases the total number of shares
authorized for issuance upon the exercise of options from the 777,779 shares
previously authorized to l,011,000 shares. In August 1997, an additional 500,000
shares were authorized for issuance.

Under the 1995 Plan, options may be granted at prices not less than 100 percent
of the fair market value of the common stock at the date of grant. Options vest
over varying years of service. Vested options are exercisable until the earlier
of ten years from the date of grant or three months after termination of
employment for options granted 


                                      F-14
<PAGE>

under the Predecessor Plans, five years from the date of grant or one month
after termination of employment for options issued under the 1995 Plan.

As of September 30, 1997, warrants remained outstanding for the right to
purchase 15,556 shares of common stock issued to certain former members of the
Board of Directors and to certain non-affiliated parties. All of the outstanding
warrants were issued over the years ended December 31, 1990 and 1991. These
warrants, which are exercisable for seven years from date of grant, are
exercisable upon grant. Warrants to purchase an additional 7,777 shares of
common stock are authorized for future issuance.

A summary of option and warrant activity under the 1995 Plan and the Predecessor
Plans is presented below:

</TABLE>

In November 1997, the Company granted 250,000 stock options to the Company's
President and Chief Executive Officer pursuant to an employment agreement. The
options may be exercised at $9.50 per share and vest over a three year period.
The fair value of the options on the date of grant was $9.75 per share. The
difference will be recognized as compensation expense ratably as the options
vest.

The Company adopted the disclosure requirements of SFAS No. 123, "Accounting for
Stock-Based Compensation," effective for the Company's December 31, 1996,
financial statements. The Company applies APB Opinion No. 25 and related
interpretations in accounting for its plans. Accordingly, compensation cost has
been recognized for its stock plans based on the intrinsic value of the stock
option at date of grant (i.e., the difference between the exercise price and the
fair value of the Company's stock).  Had compensation cost for the Company's
stock-based compensation plans been determined 


                                      F-15
<PAGE>

based on the fair value at the grant dates for awards under those plans
consistent with the method of SFAS No. 123, the Company's net income and
earnings per share would have been reduced to the pro forma amounts indicated
below:

  Fully diluted, pro forma          $.01         $.13         $.14       $(1.01)

The weighted average fair value of options granted in 1995 and 1996 was $1.61
and $4.31, respectively. The fair value of each option is estimated on the date
of grant using the Black-Scholes option-pricing model with the following
assumptions used for grants in 1995 and 1996: no dividend yield, expected
volatility of 63.0 percent, risk-free interest rate of 6.21 percent and expected
life of five years.  At September 30, 1997, the weighted average exercise price
for outstanding options was $4.66 per share.

Because SFAS No. 123 has not been applied to options granted prior to January 1,
1995, the resulting pro forma compensation cost may not be representative of
that to be expected in future years.

On March 15, 1996, the Board of Directors declared a one for six common stock
dividend payable to shareholders of record as of April 17, 1996, and distributed
on May 17, 1996. Accordingly, the fair market value (based upon quoted market
prices, as adjusted) of the additional 241,063 shares issuable, which totaled
$643,000, was charged to accumulated deficit and the respective amount was
credited to common stock and additional paid-in capital.

On July 30, 1996, the Company's Board of Directors approved a two-for-one common
stock split in the form of a 100 percent stock distribution. The distribution
was made on August 26, 1996, to common shareholders of record as of August 12,
1996. The stated par value per share of common stock was not changed from $.03
and the number of authorized shares of common stock increased from 3,333,333 to
6,666,666 shares. 


                                      F-16
<PAGE>

Accordingly, the par value of the additional shares issued was transferred from
additional paid-in capital to common stock, and all share and per share amounts
have been restated to retroactively reflect the stock split.

The Company leases certain fixed assets under long-term capital lease
agreements. These assets are included in the accompanying consolidated balance
sheets as follows:

Depreciation and amortization of these assets is computed using the
straight-line method over the shorter of the useful lives of the assets or the
term of the lease obligation.

The future maturities of capital lease obligations as of December 31, 1996, are
as follows:

OPERATING LEASES

Effective August 1, 1993, the Company entered into a lease for its corporate
headquarters facility in Fairfax, Virginia. This lease expires July 31, 1998.
The minimum commitment under this agreement amounts to $307,000. Under the terms
of the lease, the landlord provided various incentives, which have been deferred
and classified as deferred rent in the accompanying consolidated balance sheets.
These amounts are being amortized over the life of the lease.

For the years ended December 31, 1995 and 1996, and the nine months ended
September 30, 1996 and 1997, rent expense was $297,000, $290,000, $212,000 and
$258,000. During 1996, the Company incurred $53,000 of rent expense related to
space and equipment for an off-site training facility under a month-to-month
lease. During the first nine months of 1997, the Company incurred $81,000 of
rent expense related to the off-site training facility.

Effective September 1997, the Company entered into a one-year agreement with a
third party to procure outside mainframe-related data processing services. The
minimum commitment under this agreement amounts to $60,000 until termination in
August 1998.

EMPLOYEE BENEFIT PLAN

In 1988, the Company established an employee benefit plan (the "Benefit Plan")
which qualifies under Section 401(k) of the Internal Revenue Code. The Benefit
Plan allows salaried employees to contribute a portion of their compensation
toward their retirement on a tax deferred basis. The Company is required to make
contributions equal to 10 percent of the employee's contribution to the Benefit
Plan and totaled approximately $23,000 and $32,000 for the years ended December
31, 1995 and 1996, respectively, and $26,000 and $33,000 for the nine months
ended September 30, 1996 and 1997, respectively. In addition to the
aforementioned contributions, the Company, at the sole discretion of its Board
of Directors, may make profit-sharing contributions to the Benefit Plan. No
contributions were made in 1995, 1996 or 1997.


                                      F-18
<PAGE>

CONTINGENCIES

A customer has asserted that the Company did not perform on a contract and seeks
a $90,000 refund. The Company vigorously denies the assertion and management
believes that based upon the current facts it is not probable that a loss will
occur. Accordingly, no accrual has been made for this claim at December 31,
1996, or September 30, 1997.

Costs charged to cost-type U.S. Government contracts are subject to annual audit
by the Defense Contract Audit Agency or other duly authorized representatives of
the Federal government. No audits have been completed for any periods commencing
after September 30, 1991, and in the opinion of management, adjustments
resulting from the completion of such audits are not expected to have a material
impact on the Company's financial position or results of future operations.

RELATED-PARTY TRANSACTIONS

The Company incurred management consulting fees of approximately $168,000 and
$195,000 for the years ended December 31, 1995 and 1996, respectively, and
$143,000 and $158,000 for the nine months ended September 30, 1996 and 1997,
respectively, for services rendered by certain Directors of the Company. Amounts
payable for these services to companies employing these Directors were $15,000
and $12,500 at December 31, 1995 and 1996, respectively, and $0 at September 30,
1997. Amounts receivable from a company employing a director was $13,000 at
December 31, 1996.

In October 1996, the Company executed a note receivable from an officer and
shareholder for $70,000 due in full on September 30, 1999 with quarterly
interest payments at an annual rate of 1 percent over prime (approximately 9.25
percent at December 31, 1996 and 9.50% at September 30, 1997) adjusted
quarterly.

The Company issued 8,000 shares of restricted common stock to a Director for a
total compensation expense of $9,000 in consideration for services rendered
during 1995.

AMBIA

                          Independent Auditors' Report
                          ----------------------------

            We have audited the accompanying combined balance sheets of Ambia
Corporation and Software Partners, Inc. - AMBIA Division, hereafter referred to
as AMBIA as of December 31, 1995 and 1996 and the related statements of loss and
accumulated deficit and cash flows for the years then ended. The financial
statements are the responsibility of AMBIA's management. Our responsibility is
to express an opinion on the financial statements based on our audits.

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

            In our opinion, the financial statements referred to above present
fairly, in all material respects, the financial position of AMBIA as of December
31, 1995 and 1996, and the results of its operations and its cash flows for the
years then ended in conformity with generally accepted accounting principles.

            We have reviewed the balance sheet of AMBIA as of June 30, 1997 and
the related statements of income (loss) and accumulated deficit and cash flows
for the six months then ended, in accordance with Statements on Standards for
Accounting and Review Services issued by the American Institute of Certified
Public Accountants. All information included in these financial statements is
the representation of the management of AMBIA.

            A review consists principally of inquires of Company personnel and
analytical procedures applied to financial data. It is substantially less in
scope than an audit in accordance with generally accepted auditing standards,
the objective of which is the expression of an opinion regarding the financial
statements taken as a whole. Accordingly, we do not express such an opinion.


                                      F-20
<PAGE>

            Based on our review, we are not aware of any material modifications
that should be made to the financial statements as of June 30, 1997 and for the
six months then ended in order for them to be in conformity with generally
accepted accounting principles.

NOTE 1 - ACCOUNTING POLICIES

A. Nature of Business

Software Partners, Inc. - Ambia Division and Ambia Corporation, hereafter
referred to as AMBIA, develops and markets Acrobat add-on products for the
electronic publishing market in North America and Europe. Acrobat is a product
from Adobe Systems, Inc. that helps organizations publish documents on multiple
platforms from any software product.

In May 1996, Software Partners, Inc., a Delaware corporation, located in
Mountain View, California, spun-off its Ambia Division into a separate
corporation, Ambia Corporation. As a result of the spin-off, all intellectual
property was transferred, at cost, into Ambia Corporation in exchange for common
stock. Amounts due to Software Partners' other divisions were recorded as
additional paid-in capital.

The operations were carried on as Software Partners, Inc. - Ambia Division from
January 1, 1995 to April 30, 1996, and as Ambia Corporation since May 1, 1996.

The accompanying financial statements include the results of operations of
Software Partners, Inc. - Ambia Division and Ambia Corporation.

B. Use of Estimates

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

C. INTANGIBLE ASSETS AND DEFERRED CHARGES

Trademarks and patents, stated at cost less accumulated amortization, are being
amortized on the straight-line method over a three year period.

Product design costs, stated at costs less accumulated amortization, are being
amortized on a straight-line method over a two year period.

grant options for up to 500,000 shares of common stock. The exercise price of
each option is equal to the market price of the Company's stock on the date of
grant. The maximum term of the options is ten years, and they vest at the end of
four years.

The Company applies APB Opinion 25 in accounting for its fixed stock-based
compensation plan. Accordingly, no compensation costs has been recognized for
the plan. Had compensation cost been determined on the basis of fair value
pursuant to Financial Accounting Standards No. 123, net loss would have been
increased as follows:

                       1995           1996           1997

Loss proforma           171,672        693,180        86,599

The fair value of each option granted is estimated on the grant date using the
Black-Scholes model. The following assumptions were made in estimating fair
value:

                                   (UNAUDITED)

      On July 22, 1997, Infodata Systems Inc. (the "Company") acquired all of
the outstanding common stock of AMBIA Corporation ("AMBIA") in consideration for
400,000 shares of the Company's common stock (restricted as to sale) with a fair
value as determined by the Company's Board of Directors at $5.425 per share. The
total acquisition cost was approximately $2,300,000 including the direct costs
of the acquisition. Approximately $25,000 was allocated to acquired tangible
assets, $60,000 to acquired intangible assets, and $2,213,000 to goodwill. The
acquisition is being accounted for in accordance with the purchase method of
accounting and was accomplished by means of a merger of a wholly owned
subsidiary of the Company into AMBIA.

      The following unaudited Pro Forma Condensed Consolidated Statements of
Income give effect to the acquisition of AMBIA by the Company as if the
acquisition had occurred on January 1, 1996 and 1997, respectively. These pro
forma statements of income give effect, for the periods presented to the
following pro forma adjustments: (a) the increase in amortization associated
with goodwill resulting from the acquisition; and (b) the change in weighted
average common shares outstanding resulting from the issuance of 400,000 shares
of common stock in connection with the acquisition.

      The following unaudited Pro Forma Condensed Consolidated Statements of
Income should be read in conjunction with the notes thereto included herewith,
with the Company's audited and unaudited consolidated financial statements and
notes thereto for the periods presented and with AMBIA's audited and unaudited
financial statements and notes thereto for the periods presented. The unaudited
Pro Forma Condensed Consolidated Statements of Income are not necessarily
indicative of future operating results or of what would have occurred had the
acquisition been consummated at the time specified. The pro forma adjustments
are based on available information and certain adjustments that management
believes to be reasonable. In the opinion of management, all material
adjustments have been made that are necessary to present fairly the pro forma
information.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 24.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    Article 10 ("Article  10") of Chapter 9 of Title 13.1 of the Virginia  Stock
Corporation  Act ("VSCA")  authorizes a Virginia  corporation  to indemnify  its
officers,  directors,  employees and agents under certain  circumstances against
expenses and liabilities  incurred in legal  proceedings  involving such persons
because of their holding or having held such positions with the  corporation and
to purchase and  maintain  insurance  for such  indemnification.  The  Company's
Bylaws and  Paragraph  10 of its  Articles  of  Incorporation  provide  that the
Company  shall  indemnify  its  officers  and  directors  to the fullest  extent
permitted by Article 10 of the VSCA.

    Section  13.1-692.1 of the VSCA limits the personal  liability of an officer
or  director to the  corporation  for  damages  arising  out of certain  alleged
breaches of the  director's  duties to the  corporation.  No such  limitation of
liability  is  available  if the  officer or  director  engaged  in: (i) willful
misconduct or (ii) a knowing  violation of the criminal law or of any federal or
state  securities  law,  including,  without  limitation,  any claim of unlawful
insider trading or  manipulation of the market for any security.  Paragraph 9 of
the Company's Articles of Incorporation eliminates the personal liability of the
directors and officers of the Company to the fullest extent permitted by Section
13.1-692.1 of the VSCA.

ITEM 25.  OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION.

         The  Registrant  estimates  that expenses  payable by the Registrant in

ITEM 26.  RECENT SALES OF UNREGISTERED SECURITIES.

         On July 22, 1997,  the Company issued an aggregate of 400,000 shares of
Common  Stock to Alan  Fisher and Razi  Mohiuddin,  the former  shareholders  of
AMBIA, as  consideration  for the purchase of all of the  outstanding  shares of
capital  stock  of  AMBIA,  pursuant  to an  Agreement  of  Merger  and  Plan of
Reorganization. The Company relied on Section 4(2) of the Securities Act, as the
basis for an  exemption  from  registration,  because  the  transaction  did not
involve any public offering.

         On October 11, 1995,  the Company issued an aggregate of 210,000 shares
to Richard Tworek,  Mary Margaret Styer and Andrew Fregly,  the  shareholders of
Merex,  as  consideration  for the  acquisition  of Merex  pursuant  to an Asset
Purchase  Agreement and Plan of  Reorganization.  The Company  relied on Section
4(2) of the  Securities  Act as the basis for an  exemption  from  registration,
because  the  transaction did not involve any public offering.


                                      II-1


<PAGE>

         The Company has agreed to issue  shares of Common  Stock on a quarterly
basis to each of Richard  Bueschel,  Lawrence  Glazer,  Robert Leopold,  Millard
Pryor,  Jr.,  Isaac Pollak and Alan Fisher,  the  non-employee  directors of the
Company  as  payment of  consulting  fees for 1997 in the amount of $10,000  per
non-employee  director.  Through September 30, 1997, each non-employee  director
was entitled to 872 shares of Common Stock.  Certificates evidencing such shares
and the number of shares to which the  non-employee  directors  will be entitled
for the last  quarter of 1997 will be issued in  January,  1998.  The Company is
relying on Section 4(2) of the Securities Act as the basis for an exemption from
registration,  because these shares will be issued by the Company  solely to its
non-employee directors, and thus will not involve any public offering.

ITEM 28.  UNDERTAKINGS.

(a)      The undersigned Registrant hereby undertakes:

                  (1) To file,  during  any  period  in which it offers or sells
securities, a post-effective amendment to this Registration Statement to;

                        (i)     Include  any  prospectus   required  by  Section
                                10(a)(3) of the Securities Act;

                        (ii)    Reflect  in the  prospectus  any facts or events
                                which,  individually  or  together,  represent a
                                fundamental  change  in the  information  in the
                                Registration Statement;

                        (iii)   Include  any  additional  or  changed   material
                                information on the plan of distribution.

                  (2) For determining  liability under the Securities Act, treat
each  post-effective  amendment as a new registration of the securities offered,
and the  offering of such  securities  at that time to be the initial  bona fide
offering.

                  (3)  File  a   post-effective   amendment   to   remove   from
registration  any  of the  securities  that  remain  unsold  at  the  end of the
offering.

         (b)  Insofar  as  indemnification  for  liabilities  arising  under the
Securities Act may be permitted to directors,  officers and controlling  persons
of the  Registrant  pursuant to the  foregoing  provisions,  or  otherwise,  the
Registrant  has  been  advised  that  in  the  opinion  of the  Commission  such
indemnification  is against public policy as expressed in the Securities Act and
is, therefore, unenforceable.

                    In the event that a claim for  indemnification  against such
liabilities  (other than the payment by the  Registrant of expenses  incurred or
paid by a  director,  officer or  controlling  person of the  Registrant  in the
successful  defense of any  action,  suit or  proceeding)  is  asserted  by such
director,  officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter


                                      II-4

<PAGE>
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as  expressed  in the  Securities  Act and will be  governed by the final
adjudication of such issue.

subsidiaries (the "Company") as of and for the years ended December 31, 1995 and
1996, included in this registration statement and have issued our report thereon
dated  December  18,  1997.  Our audits  were made for the purpose of forming an
opinion on the basic financial  statements taken as a whole. The schedule listed

                                   ARTICLE II
                         TERMS AND CONDITIONS OF MERGER

        The terms and  conditions  of the merger (in addition to those set forth
elsewhere in the Plan) are as follows;

(a) Upon and following the Effective Time of the merger:

     (1) The Constituent Corporations shall be merged into a single corporation,
which shall be  Infodata  Virginia,  the  corporation  designated  herein as the
Surviving Corporation.

     (2) The separate existence of Infodata shall cease.

     (3) The Surviving  Corporation  shall thereupon and thereafter  possess all
the rights,  privileges,  powers, immunities and franchises, of a public as well
as of a private nature, and be subject to all the restrictions, disabilities and
duties of each Constituent Corporation;  and the rights, privileges,  powers and
franchises of each Constituent Corporation, and all property, real, personal and
mixed, and all debts due to either Constituent  Corporation on whatever account,
including  subscriptions  for stock,  and all other choses in action and all and
every other interest, of or belonging to each Constituent Corporation,  shall be
taken and deemed to be  transferred  to and vested in the Surviving  Corporation
without further act or deed; and all property,  rights,  privileges,  powers and
franchises,  and all and every other interest shall be thereafter as effectually
the  property  of the  Surviving  Corporation  as they  were  of the  respective
Constituent  Corporations,  and the title to any real  estate  vested by deed or
otherwise in either  Constituent  Corporation  shall not revert or be in any way
impaired by reason of the merger, but all rights of creditors and all liens upon
any property of either  Constituent  Corporation shall be preserved  unimpaired,
and all debts, liabilities and duties of the respective Constituent Corporations
shall  thenceforth  attach  to the  Surviving  Corporation  and may be  enforced
against it to the same extent as if said debts,  liabilities and duties had been
incurred or contracted by it.  Specifically,  but not by way of limitation,  the
Surviving Corporation shall be responsible and liable to dissenting shareholders
of  Infodata  and  any  action  or  proceeding   whether   civil,   criminal  or
administrative,  pending by or against either  Constituent  Corporation shall be
prosecuted as if the merger had not taken place,  or the  Surviving  Corporation
may be substituted in such action or proceeding.

     (4)  All  corporate  acts,  plans,  policies,   contracts,   approvals  and
authorizations of Infodata and its shareholders,  Board of Directors, committees
elected or appointed by the Board of Directors,  officers and agents, which were
valid and effective  immediately prior to the Effective Time of the merger shall
be taken for all purposes as the acts, plans, policies, contracts, approvals and
authorizations  of the  Surviving  Corporation  and  shall be as  effective  and
binding  thereon as the same were with  respect to  Infodata.  The  employees of
Infodata shall become the employees of the Surviving Corporation and continue to
be entitled to the same rights and  benefits  which they enjoyed as employees of
Infodata.

     (5) The assets,  liabilities,  reserves  and  accounts of each  Constituent
Corporation  shall be recorded on the books of the Surviving  Corporation at the
amounts at which they, respectively,  shall then be carried on the books of such
Constituent   Corporation   subject  to  such  adjustments  or  eliminations  of
intercompany items as may be appropriate in giving effect to the merger.

     (6) All obligations of Infodata under any and all employee benefit plans in
effect as of the Effective Time of the merger, or with respect to which employee
rights or  accrued  benefits  are  outstanding  as of such time,  including  the
assumption of all  outstanding  stock options  issued under the Incentive  Stock
Option Plan and the  Non-Qualified  Stock Option Plan of Infodata,  the proposed
1995 Stock  Option Plan of  Infodata,  if adopted,  and any  warrants  issued by
Infodata  pursuant  to its Stock  Warrant  Purchase  Plan,  shall be  assumed by
Infodata  Virginia as of the Effective  Time of the merger;  provided,  however,
that the common stock of Infodata Virginia shall be substituted for common stock
of Infodata thereunder, without any action on the part 


                                       A-2

<PAGE>

        
of the holder  thereof.  As of the Effective Time of the merger,  Infodata shall
adopt and  continue in effect all such  employee  benefit  and warrant  purchase
plans, upon the same terms and conditions as were in effect immediately prior to
the merger and Infodata Virginia shall reserve that number of shares of Infodata
Virginia  common stock which is equal to the number of shares of common stock of
Infodata  that is  reserved  under  any and all  employee  benefit  and  warrant
purchase plans of Infodata as of the Effective Time of the merger.

     (b) The Board of Directors,  and the members thereof, the committees of the
Board of  Directors,  and the  members  thereof,  and the  officers  of Infodata
immediately  prior to the Effective  Time of the merger shall be and  constitute
the Board of Directors,  and the members thereof, the committees of the Board of
Directors,   and  the  members  thereof,  and  the  officers  of  the  Surviving
Corporation,  respectively,  to  serve in  accordance  with  the  Bylaws  of the
Surviving  Corporation  until their  respective  successors shall have been duly
elected and qualified.

                                   ARTICLE III
                     CAPITALIZATION OF SURVIVING CORPORATION
                    AND MANNER AND BASIS OF CONVERTING SHARES

        The total authorized capital stock of the Surviving Corporation shall be
as set forth in the Articles of Incorporation of the Surviving Corporation, that
is 3,333,333 shares of common stock, $.03 par value per share (the "Common Stock
of Surviving  Corporation"),  and 500,000 shares of preferred  stock,  $1.00 par
value per share (the "Preferred Stock of Surviving Corporation").

        The  manner  and  basis  of  converting   shares  of  each   Constituent
Corporation  into shares of the Surviving  Corporation  and the mode of carrying
the merger into effect are as follows:

        (a) The 1,000 shares of common stock of Infodata Virginia owned and held
by Infodata  immediately prior to the Effective Time of the merger shall, at the
Effective Time of the merger, be deemed to have been cancelled immediately prior
thereto  and no stock of the  Surviving  Corporation  shall be issued on account
thereof.

        (b) At the Effective  Time of the merger,  each share of common stock of
Infodata outstanding at the Effective Time of the merger shall be converted into
one  fully  paid and  nonassessable  share  of  Common  Stock  of the  Surviving
Corporation,  without  any action on the part of the holder  thereof.  After the
Effective Time of the merger,  each holder of an outstanding  certificate  which
prior thereto  represented shares of common stock of Infodata shall be entitled,
upon  surrender  thereof  to any  transfer  agent  for the  Common  Stock of the
Surviving  Corporation,  to  receive  in  exchange  therefor  a  certificate  or
certificates  representing the number of shares of Common Stock of the Surviving
Corporation into which the shares of the common stock of Infodata so surrendered
shall have been converted as aforesaid of such  denominations  and registered in
such  names  as such  holder  may  request.  Until  so  surrendered,  each  such
outstanding  certificate  which,  prior  to the  Effective  Time  of the  merger
represented  shares of common stock of Infodata shall for all purposes  evidence
the  ownership of the shares of Common Stock of the Surviving  Corporation  into
which such shares shall have been so converted.

     (c) At the Effective Time of the merger,  each share of preferred  stock of
Infodata outstanding at the Effective Time of the merger shall be converted into
one  fully-paid  and  nonassessable  share of Preferred  Stock of the  Surviving
Corporation,  without  any action on the part of the holder  thereof.  After the
Effective Time of the merger,  each holder of an outstanding  certificate  which
prior  thereto  represented  shares  of  preferred  stock of  Infodata  shall be
entitled upon surrender thereof to any transfer agent for the Preferred Stock of
the Surviving  Corporation,  to receive in exchange  therefore a certificate  or
certificates  representing  the  number  of  shares  of  Preferred  Stock of the
Surviving  Corporation  into which the shares of preferred  stock of Infodata so
surrendered  shall have been converted as aforesaid,  of such  denominations and
registered in such names as such holder may request. Until so surrendered,  each
such outstanding  certificate  which, prior to the Effective Time of the merger,
represented  shares  of  preferred  stock of  Infodata  shall  for all  purposes
evidence the ownership of shares of Preferred Stock of the Surviving Corporation
into which such shares shall have been so converted.


                                      A-3

<PAGE>

        (d) All  shares of Common  Stock and  Preferred  Stock of the  Surviving
Corporation  into which shares of common stock and  preferred  stock of Infodata
shall have been  converted  pursuant to this ARTICLE III shall be issued in full
satisfaction of all rights pertaining to such converted shares.

        (e) If any  certificate of shares of Common Stock or Preferred  Stock of
the Surviving Corporation is to be issued in a name other than that in which the
certificate  surrendered  in exchange  therefore  is  registered,  it shall be a
condition of the issuance  thereof that the certificate so surrendered  shall be
properly  endorsed and otherwise in proper form for transfer and that the person
requesting  such  exchange  pay  to  the  Surviving  Corporation  or  any  agent
designated by it any transfer or other taxes  required by reason of the issuance
of a certificate  for shares of Common Stock or Preferred Stock of the Surviving
Corporation  in any  name  other  than  that  of the  registered  holder  of the
certificate  surrendered,  or establish  to the  satisfaction  of the  Surviving
Corporation or any agent  designated by it that such tax has been paid or is not
payable.

        (f)  Notwithstanding the provisions of this ARTICLE III, any outstanding
shares of common stock or preferred stock of Infodata held by  shareholders  who
shall have elected to dissent from the merger and who shall have  exercised  and
perfected  appraisal  rights  with  respect to such  shares in  accordance  with
Section 623 of the New York Business Corporation Law ("Dissenting Shareholders")
shall not be converted  into shares of Common  Stock or  Preferred  Stock of the
Surviving  Corporation but shall be entitled to receive only such  consideration
as shall be provided in said Section 623, except that common stock and preferred
stock of Infodata  outstanding at the Effective Time of the merger and held by a
Dissenting  Shareholder  who shall  thereafter  withdraw his election to dissent
from the merger or lose his right to dissent from the merger as provided in said
Section 623,  shall be deemed  converted as of the Effective Time of the merger,
into such number of shares of Common Stock or Preferred  Stock of the  Surviving
Corporation  as such holder  otherwise  would have been entitled to receive as a
result of the merger.

                                   ARTICLE IV
                      ARTICLES OF INCORPORATION AND BYLAWS

                                    ARTICLE V
                     OTHER PROVISIONS WITH RESPECT TO MERGER

the  requirements  of the laws of the  States of New York and  Virginia  and the
obtaining of all necessary regulatory approvals, all required documents shall be
executed,  filed and recorded  and all  required  acts shall be done in order to
accomplish  the merger under the  provisions of the  applicable  statutes of the
States of New York and Virginia.

        (b) The Plan may be terminated  at any time prior to the Effective  Time
of the merger, whether before or after action thereon by the shareholders of the

<PAGE>

elect to exercise the right to dissent under  applicable  provisions of New York
law in connection with the merger contemplated hereby, or (iii) by action of the
Board of Directors of either of the Constituent  Corporations if there shall not
have been  received  an opinion of counsel to the effect  that (A) the merger of

Virginia,  (C) the tax basis of the shares of stock of the Surviving Corporation
received by the  shareholders  of Infodata  will be the same as the tax basis of

will  include  the  holding  period of the shares of capital  stock of  Infodata
exchanged therefor,  provided that such shares of capital stock of Infodata were
held as capital assets at the Effective Time of merger, (E) no gain or loss will
be recognized  by Infodata  Virginia or Infodata as the result of the receipt by
Infodata  Virginia  of all the  assets of  Infodata  in  exchange  for shares of

all the  liabilities of Infodata and (F) the tax basis of the assets of Infodata

        (c) If the merger is consummated,  the Surviving  Corporation shall bear
and pay all costs and expenses incurred by each of the Constituent Corporations.

Shareholder  of  Infodata  against  the  Surviving  Corporation.  The  Surviving
Corporation  irrevocably  appoints the Secretary of the State of New York as its
agent to  accept  service  of  process  in any such  proceeding.  The  Surviving
Corporation  will promptly pay to the  Dissenting  Shareholders  of Infodata the
amounts,  if any,  to which they shall be entitled  under the New York  Business
Corporation Law with respect to the rights of Dissenting Shareholders,  provided
such Dissenting Shareholders act in strict compliance with the provisions of the
New York Business Corporation Law governing rights of Dissenting Shareholders in
the case of a merger.

        (e) Infodata shall duly convene the 1995 Annual Meeting of  Shareholders

                                     between

                             LANDMARK BUILDING LEASE



1. PARTIES. This Lease dated, for reference purposes only, July 20, 1993, by and
between LANDMARK INVESTMENTS,  LIMITED ("Landlord") and SOFTWARE PARTNERS,  INC.
("Tenant"), who agree as follows:

2.  PREMISES.  Landlord  leases to Tenant,  and Tenant  leases from Landlord the
office space  located in Mountain  View,  California,  94043,  described as 2013
Landings L\Drive, outlined in Exhibit "A" ("Premises").  Premises have an agreed
area o  approximately  One Thousand One Hundred and One (1,101)  rentable square
feet.

3. TERM.  The term of this Lease  shall be for three (3)  years,  commencing  on
September 1, 1993 and ending on August 31, 1996.

4. RENT.

4.1 Tenant  shall pay to  Landlord  as rent for the  Premises,  without  demand,
deduction,  or off-set,  the sum of One  Thousand  Seven  Hundred Six and 55/100
Dollars  ($1,706.55)  on or before the first day of each and every  month of the
term of this Lease, the first monthly payment to be made  concurrently  with the
execution hereof. If the commencement date is not the first day of a month or if
the  Lease  termination  date is not the last day of a month,  the rent  payable
hereunder shall be prorated,  based upon a thirty day month, at the current rate
for the fractional  month during which this Lease commences  and/or  terminates.
Any rent payable for a partial month directly  following the  commencement  date
shall be payable on the first day of the first full calendar  month of the term.
Rent shall be paid to Landmark  Investments,  limited,  at 2093 Landings  Drive,
Mountain View, CA 94043.

4.2 Rent  provided  for in 4.1 above  shall not be  subject  to  consumer  price
adjustments.

4.3 Late  Charges.  Tenant  hereby  acknowledges  that late payment by Tenant to
Landlord of rent or other sums due hereunder  will cause Landlord to incur costs
not  contemplated  by this Lease,  the exact  amount of which will be  extremely
difficult to ascertain.  Such costs include,  


                                        1
<PAGE>


but are not limited to,  processing  and  accounting  charges,  and late charges
which may be  imposed  upon  Landlord  by terms of any  mortgage  or trust  deed
covering the Premises.  Accordingly,  if any installment of rent or of a sum due
from Tenant shall not be received by Landlord or  Landlord's  designees by 12:00
noon on the fifth (5th) day of each month of the term hereof,  then Tenant shall
pay to Landlord a late charge equal to five percent (5%) of such overdue amount.
The parties hereby agree that such late charges  represent a fair and reasonable
estimate of the cost that  Landlord  will incur by reason of the late payment by
Tenant.  Acceptance  of such  late  charges  by the  Landlord  shall in no event
constitute a waiver of

Tenant's default with respect to such overdue amount,  nor prevent Landlord from
exercising any of the other rights and remedies granted hereunder.

5.  SECURITY  DEPOSIT.  On  execution of this Lease,  Tenant shall  deposit with
Landlord  $1,706.55 as a security  deposit for the  performance by Tenant of the
provisions of this Lease. If Tenant is in default, Landlord can use the security
deposit, or any portion of it, to cure the default or to compensate Landlord for
all damage sustained by Landlord  resulting from Tenant's default.  Tenant shall
immediately on demand pay to Landlord a sum equal to the portion of the security
deposit  expended or applied by Landlord as provided in this  paragraph so as to
maintain the security deposit in the sum initially  deposited with Landlord.  If
Tenant  is not in  default  at the  expiration  or  termination  of this  Lease,
Landlord  shall,  no later than  fourteen  (14) days after lease  expiration  or
termination,  return to Tenant (or at Landlord's option, to the last assignee of
Tenant's  interest  hereunder),  the balance of the security  deposit.  Landlord
shall not be required to keep this  security  deposit  separate from its general
funds, and Tenant shall not be entitled to interest on such deposit.

6. POSSESSION.

6.1 If Landlord,  for any reason  cannot  deliver  possession of the Premises on
Tenant at the  commencement of the term hereof,  this Lease shall not be void or
voidable nor shall Landlord be liable to Tenant for any loss or damage resulting
therefrom,  nor shall the expiration date of the above term be extended, but, in
that event,  all rent shall be abated during the period between the commencement
of said term and the time when Landlord delivers possession.

6.2 In the event that Landlord  shall permit Tenant to occupy the Premises prior
to the commencement  date of the term, such occupancy shall be subject to all of
the  provisions  of this Lease and said early  possession  shall not advance the
termination  date hereinabove  provided.  Rent shall be prorated and prepaid for
early occupancy at the current rate.



                                        2

Landlord.

7.2 Uses Prohibited.

nor bring or keep  anything  therein  which will  increase the existing  rate or
affect any fire or other insurance upon the building or any of its contents,  or
cause a cancellation of any insurance  policy covering said building or any part
thereof or any of its contents,  nor shall Tenant sell or permit to be kept used
or sold in or about said  Premises any articles or  substances,  inflammable  or
otherwise, which may be prohibited by a standard form policy of fire insurance.

which will in any way obstruct or interfere  with the rights of other tenants of
the building or injure or annoy them or use or allow the Premises to be used for
any unlawful or objectionable purpose.

c. Tenant shall not use the  Premises or permit  anything to be done in or about
the Premises  which will in any way conflict  with any law now in force or which

board  of  fire   underwriters  or  other  similar  body  relating  to  Tenant's
improvements or acts.

8.  ALTERATIONS  AND ADDITION.  Tenant shall not make or allow any  alterations,
additions or improvements of or to the Premises without Landlord's prior written
consent.  Any such alterations,  additions or improvements,  including,  but not
limited to,  wallcovering,  paneling and built-in  cabinet  work,  but excepting
movable furniture and trade fixtures,  shall become a part of the realty,  shall
belong to the Landlord and shall be surrendered  with the Premises at expiration
or  termination  of the Lease.  If Landlord  consents  to any such  alterations,
additions or  improvements  by Tenant,  they shall be made by Tenant at Tenant's
cost, and any contractor or person  selected by Tenant to perform the work shall
first be approved  of, in  writing,  by  Landlord.  Upon  expiration,  or sooner
termination  of the term hereof,  Tenant shall,  upon written demand by Landlord
promptly remove any  alterations,  additions or improvements  made by Tenant and
designated  by Landlord to be removed.  Such removal and repair of any damage to
the premises caused by such removal shall be at Tenant's cost.

<PAGE>

9. LIENS.  Tenant shall keep the Premises and the property in which the Premises
are situated  free from any liens arising out of any work  performed,  materials
furnished or  obligations  incurred by Tenant.  Landlord  may require  Tenant to
provide  Landlord,  at Tenant's  cost, a lien and  completion  bond in an amount
equal to one and one-half (1-1/2) times the estimated cost of any  improvements,
additions,  or alterations by Tenant,  to insure Landlord against  liability for
mechanic's and materialmen's liens and to insure completion for the work.

10. REPAIRS AND MAINTENANCE.  By taking possession of the Premises, Tenant shall
be  deemed  to have  accepted  the  Premises  as being in good  sanitary  order,
condition and repair. Tenant shall at Tenant's cost, keep the premises and every
part thereof in good  condition and repair except for damages from causes beyond
the  control  of Tenant  and  ordinary  wear and  tear.  Tenant  shall  upon the
expiration  or sooner  termination  of this Lease  surrender the Premises to the
Landlord in good condition, ordinary wear and tear and damage from causes beyond
the reasonable control of the Tenant excepted.  Unless specifically  provided in
an addendum to this Lease,  Landlord shall have no obligation to alter, remodel,
improve  repair,  decorate  or paint the  Premises  or any part  thereof and the
parties  hereto  affirm that  Landlords  has made no  representations  to Tenant
respecting the condition of the premises or the building  except as specifically
herein set forth.  Notwithstanding  the above provisions,  Landlord shall repair
and maintain the  structural  portions of the  building,  including the standard
plumbing,  air  conditioning,   heating  and  electrical  systems  furnished  by
Landlord,  unless such maintenance and repairs are caused in part or in whole by
the act,  neglect,  fault or  omission  of any duty by the  Tenant,  its agents,
employees or invitees, in which case Tenant shall pay to Landlord the reasonable
cost of such maintenance and repairs.  Tenant shall give Landlord written notice
of any required  repairs or  maintenance.  Landlord  shall not be liable for any
failure  to repair or to perform  any  maintenance  unless  such  failure  shall
persist  for  an  unreasonable  time  after  written  notice.   Any  repairs  or
maintenance to  supplemental  cooling  equipment  required for Tenant's  special
needs are the responsibility of Tenant. Except as specifically herein set forth,
there shall be no  abatement  of rent or  liability of Landlord by reason of any
injury to or interference  with Tenant's business arising from the making of any
repairs,  alterations  or  improvements  to any  portion of the  building or the
Premises or to fixtures,  appurtenances and equipment therein. Tenant waives the
right to make repairs at Landlord's  expense under any law, statute or ordinance
now or hereafter in effect.

11. ASSIGNMENTS AND SUBLETTING. Tenant shall not, 


                                      4
<PAGE>

voluntarily or by operation of law, assign,  transfer,  or encumber its interest
under this Lease or in the Premises nor sublease all or any part of the premises
or allow any other  person or entity  (except  Tenant's  employees,  agents  and
invitees)  to occupy or use all or any part of the  premises  without  the prior
written  consent  of  Landlord.  Landlord's  consent  shall not be  unreasonably
withheld.  Any such consent shall not release Tenant from  liability  hereunder,
and a consent  to one  assignment,  subletting,  occupation  or use shall not be
deemed a consent to any subsequent  assignment,  subletting,  occupation or use.
Any such  purported  assignment,  subletting,  or  permission  to  occupy or use
without  such consent from  Landlord  shall be void and shall,  at the option of
Landlord,  constitute  a  default  under  this  Lease.  Tenant  immediately  and
irrevocably assigns to Landlord, as security for Tenant's obligations under this
Lease,  all  rent  from  any  subletting  of all or a part  of the  Premises  as
permitted by this Lease, and Landlord,  as assignee and as attorney-in-fact  for
Tenant,  or a receiver  for Tenant  appointed  on  Landlord's  application,  may
collect  such rent and apply it toward  Tenant's  obligations  under this Lease;
except that,  until the occurrence of an act of default by Tenant,  Tenant shall
have the right to collect such rent.

12. HOLD HARMLESS.  Except as to claims based on the sole  negligence or willful
misconduct  of Landlord,  its agents or  employees,  Tenant shall hold  Landlord
harmless  from any claims  arising from Tenant's use of the premises or from any
activity  permitted by Tenant in or about the Premises,  and any claims  arising
from any breach or default in Tenant's  performance of any obligation  under the
terms of this  Lease.  If any action or  proceeding  is brought by reason of any
such claim in which Landlord is named as a party,  Tenant shall defend  Landlord
therein at Tenant's  expense by counsel  reasonably  satisfactory  to  Landlord.
Landlord and its agents shall not be liable for any damage to property entrusted
to employees of the building, nor for loss or damage to any property by theft or
otherwise,  nor from any injury to or damage to persons  or  property  resulting
from any cause  whatsoever,  unless  caused by or due to the sole  negligence or
willful misconduct of Landlord, its agents, or employees.  Landlord shall not be
liable for any latent  defect in the  Premises or in the  building of which they
are a part.  Tenant  shall give  prompt  notice to  Landlord  in case of fire or
accidents  in the  Premises  or in the  building  or of  alleged  defects in the
building, fixtures or equipment.

13. INSURANCE.

13.1  Coverage.  Tenant shall assume the risk of damage to any fixtures,  goods,
inventory,  merchandise,  equipment,  furniture and leasehold improvements,  and
Landlord  shall not be liable for  injury to  Tenant's  business  or any loss of


                                       5
<PAGE>

income therefrom relative to such damage.  Tenant shall, at all times during the
term of this  Lease,  and at its own cost,  procure  and  continue  in force the
following insurance coverage.

a.  Comprehensive  public  liability  insurance,  insuring  Landlord  and Tenant
against  any  liability  arising  out  of  the  ownership,   use,  occupancy  or
maintenance of the Premises and all areas appurtenant thereto.

13.2  Insurance  Policies.  The  limits of said  insurance  policies  shall not,
however,  limit the  liability  of the Tenant  hereunder.  Tenant may carry said
insurance under a blanket policy,  providing,  however, said insurance by Tenant
shall name  Landlord as an additional  insured.  If Tenant shall fail to procure
and maintain said insurance, Landlord may, but shall not be required to, procure
and maintain same, but at the expense of Tenant.  Insurance  required  hereunder
shall be in companies that rate B+ or better in "Best's Insurance Guide". Tenant
shall deliver to Landlord prior to occupancy of the premises  copies of policies
of insurance  required  herein or  certificates  evidencing  the  existence  and
amounts of such insurance with loss payable  clauses,  satisfactory to Landlord.
No policy shall be cancelable  or subject to reduction of coverage  except after
fifteen  (15) days prior  written  notice to  Landlord.  The minimum  acceptable
amount of comprehensive  liability insurance is $1,000,000 against claims in any
occurrence, and property damage insurance in an amount of not less than $100,000
per occurrence,  or combined single limit of $1,000,000  comprehensive liability
and property damage insurance.

13.3  Waiver of  Subrogation.  As long as their  respective  insurers so permit,
Landlord and Tenant each hereby waive any and all rights of recovery against the
other for any loss or damage occasioned to such waiving party or its property of
others  under its  control  to the  extent  that such loss or damage is  insured
against under any fire or extended  coverage  insurance  policy which either may
have in force at the time of such loss or damage.  Each party  shall  obtain any
special  endorsement,  if required by their insurer, to evidence compliance with
the aforementioned waiver.

14. SERVICE AND UTILITIES.

14.1 Landlord's  Obligations.  Landlord agrees to furnish to the Premises during
reasonable  hours of generally  recognized  business  days to be  determined  by
Landlord, and subject to the Rules and Regulations of the building,  electricity

conditioning  required  in  Landlord's  judgment  for  the  comfortable  use and
occupancy of the  Premises,  janitorial,  window  washing and elevator  service.

<PAGE>

shall  also  maintain  the common  areas and keep  lighted  the  common  stairs,
gallerias,  entries and toilet room and the  parking  areas until late  evening.
Landlord  shall not be  liable  for and  Tenant  shall  not be  entitled  to any
reduction  of rental  by reason of  Landlord's  failure  to  furnish  any of the
foregoing when such failure is caused by accident,  breakage,  repairs, strikes,
lockouts or other labor  disturbances or labor disputes of any character,  or by
any other  cause,  similar  or  dissimilar,  beyond  the  reasonable  control of
Landlord.

14.2  Tenant's  Obligation.  Tenant  shall pay for,  prior to  delinquency,  all
telephone and all other  materials and  services,  not expressly  required to be
paid by Landlord, which may be furnished to or used in, on or about the Premises
during  the term of this  Lease.  Tenant  will not,  without  the prior  written
consent of Landlord and subject to any conditions which Landlord may impose, use
any  apparatus  or device in the  Premises  which will in any way  increase  the
amount of  electricity  or water  usually  furnished  for use of the Premises as
general office space If Tenant shall require water or electric current in excess
of that usually  furnished or supplied for use of the Premises as general office
space,  Tenant  shall  first  procure  the consent of  Landlord.  Wherever  heat
generating  machines or  equipment  are used in the  Premises  which  affect the
temperature  otherwise  maintained  by the  air  conditioning  system,  Landlord
reserves  the  right to  install  supplementary  air  conditioning  units in the
Premises and the cost thereof,  including the cost  installation,  operation and
maintenance  thereof,  shall  be paid by  Tenant  to  Landlord  upon  demand  by
Landlord.  Landlord shall not be liable for Landlord's failure to furnish any of
the  foregoing  when such failure is caused by any cause  beyond the  reasonable
control of Landlord.  Landlord shall not be liable under any  circumstances  for
loss of or injury to property,  however occurring, in connection with failure to
furnish any of the foregoing.

15. PROPERTY TAXES. Tenant shall pay before  delinquency,  all personal property
taxes levied or assessed and which  become  payable  during the term hereof upon
all Tenant's equipment, furniture, fixtures and personal property located in the
Premise.  Landlord shall pay all property taxes on the land and building, except
should the California  Constitution be changed in a way that results in a higher
or lower tax on the Premises than the annual  increases now a matter of law, any
such increase or decrease  shall be passed through to tenant on a prorated basis
as an item separate from any CPI  adjustments.  Tenant shall pay to Landlord its
share of such taxes,  if any,  within  thirty  days after  delivery to Tenant by
Landlord of a statement in writing setting forth the amount of such taxes.

16. RULES AND REGULATIONS.  Tenant shall faithfully  observe 


                                       7
<PAGE>

and comply with the rules and regulations attached as Exhibit "B" to this Lease,
as well as such  rules and  regulations  that  Landlord  shall from time to time
promulgate. Landlord reserves the right from time to time to make all reasonable
modifications to those rules which shall be binding to Tenant upon delivery of a
copy of them to  Tenant.  Landlord  shall not be  responsible  to Tenant for the
nonperformance of any of said rules by any other tenant.

17. HOLDING OVER. If Tenant remains in possession  without  Landlord's  consent,
after termination of the Lease, by lapse of time or otherwise,  Tenant shall pay
Landlord for each day of such retention  one-fifteenth (1/15th) of the amount of
the monthly rental for the last month prior to such termination and Tenant shall
also pay all costs, expenses and damages sustained by Landlord by reason of such
retention,  including,  without  limitation,  claims made by a succeeding tenant
resulting from Tenant's failure to surrender the Premises.

18. ENTRY BY LANDLORD.  Landlord reserves the right to enter the premises at any
time to inspect the  Premises,  to provide  any  service  for which  landlord is
obligated  hereunder,  to submit  the  Premises  to  prospective  purchasers  or
tenants, to post notices of nonresponsibility,  and to alter, improve,  maintain
or repair the  Premises or any portion of the building of which the Premises are
a part that  Landlord  deems  necessary or desirable,  all without  abatement of
rent.  Landlord  may erect  scaffolding  and other  necessary  structures  where
reasonably required by the character of the work to be performed,  but shall not
block entrance to the Premises and not interfere with tenant's business,  except
as reasonably required for the particular  activity by Landlord.  Landlord shall
not be  liable  in any  manner  for  any  inconvenience,  disturbance,  loss  of
business,  nuisance,  interference with quiet enjoyment, or other damage arising
out of Landlord's  entry on the Premises as provided in this  paragraph,  except
damage,  if any,  resulting from the negligence or wilful misconduct of Landlord
of its  authorized  representative.  Landlord  shall  retain a key with which to
unlock all doors into, within and about the Premises, excluding Tenant's vaults,
safes and files. In an emergency  Landlord shall have the right to use any means
which  Landlord  deems  reasonably  necessary to obtain  entry to the  Premises,
without  liability  to Tenant,  except for any failure to exercise  due care for
Tenant's  property.  Any such entry to the  Premises  by  Landlord  shall not be
construed  or deemed to be forcible or unlawful  entry into or a detainer of the
Premises or an eviction of Tenant from the Premises or any portion thereof.

19. RECONSTRUCTION.  If the Premises or the building of which the Premises are a
part are damaged by fire or other peril covered by extended coverage  insurance,
Landlord agrees to make repairs and restorations to the extent and in the manner
possible  at a cost not  exceeding  the  proceeds of the  


                                       8
<PAGE>

insurance  received by Landlord.  If the cost of repair and restoration  exceeds
the amount of proceeds received from insurance,  Landlord may elect to terminate
this Lease by giving notice to Tenant within twenty (20) days after  determining
that the cost will exceed such  proceeds.  If Landlord  proceeds with repair and
restoration,  this Lease  shall  remain in full force and  effect,  except  that
Tenant shall be entitled to a proportionate reduction of rent while such repairs
are being  made.  The rent  reduction  shall be based  upon the  extent to which
repair and restoration activity materially  interferes with Tenant's business at
the Premises,  provided, however, that if the damage was occasioned by the fault
or neglect of Tenant,  its agents or employees,  there shall not be an abatement
of rent.

20.      DEFAULT; REMEDIES.

20.1 Default.  The occurrence of any of the following shall constitute a default
by Tenant:

a.  Failure  by Tenant to pay the rent or other  monies  when  due,  where  such
failure continues or three (3) business days after written notice by Landlord to
Tenant.

b. Abandonment of the Premises by Tenant.

c.  Failure by Tenant to perform  any other  provision  of this Lease where such
failure to perform is not cured  within  thirty (30) days after  notice has been
given to Tenant;  provided,  however,  that if the nature of the default is such
that the same  cannot  reasonably  be cured  within said thirty (30) day period,
Tenant  shall not be deemed to be in default if Tenant  shall within such period
commence such cure and thereafter diligently prosecute the same to completion.

d. The making by Tenant of any general assignment or general arrangement for the
benefit of  creditors;  the filing by or  against  Tenant of a petition  to have
Tenant  adjudged a bankrupt or of a petitio for  reorganization  or  arrangement
under any law relating to bankruptcy  (unless,  in the case of a petition  filed
against Tenant,  same is dismissed  within sixty (60) days; the appointment of a
trustee or receiver to take possession of  substantially  all of Tenant's assets
located at the Premises or of Tenant's interest in this Lease,  where possession
is not restored to Tenant within thirty (30) days; or the attachment,  execution
or other judicial seizure of substantially all of Tenant's assets located at the
Premises  or of  Tenant's  interest  in this  Lease,  where such  seizure is not
discharged within thirty (30) days.

20.2     Remedies.  In the event of any such default Landlord may:


                                       9
<PAGE>

Maintain  this Lease in full force and  effect  and  recover  the rent and other
monetary  charges as they  become due,  without  terminating  Tenant's  right to
possession  irrespective of whether Tenant shall have abandoned the Premises. In
the event  Landlord  elects not to terminate the Lease,  Landlord shall have the
right to attempt to re-let the Premises at such rent and upon such condition and
for such a term,  and to do all acts  necessary  to  maintain  or  preserve  the
Premises as Landlord deems reasonable and necessary without being deemed to have
elected to terminate  the Lease,  including  removal of all persons and property
from the Premises. Such property may be removed and stored in a public warehouse
or elsewhere at the cost of and for the account of Tenant. In the event any such
reletting occurs,  this Lease shall terminate  automatically upon the new tenant
taking possession of the Premises.  Notwithstanding that Landlord fails to elect
to terminate the Lease  initially,  Landlord at any time during the term of this
Lease may elect to terminate  this Lease by virtue of such  previous  default of
Tenant.

Terminate  Tenant's right to possession by any lawful means,  in which case this
Lease shall terminate and Tenant shall immediately  surrender  possession of the
Premises to Landlord.  In such event  Landlord shall be entitled to recover from
Tenant all damages incurred by Landlord by reason of Tenant's default, including
without limitation thereto, the following: (1) the worth at the time of award of
any unpaid rent which  would have been  earned at the time of such  termination;
plus (2) the worth at the time of award of the amount by which the  unpaid  rent
which would have been earned after  termination  until the time of award exceeds
the amount of such rental  loss that is proved  could have  reasonably  avoided;
plus (3) the worth at the time of award of the amount by which  unpaid  rent for
the  balance  of the term  after the time of award  exceeds  the  amount of such
rental  loss  that is proved  could be  reasonably  avoided;  plus (4) any other
amount necessary to compensate Landlord for all the detriment proximately caused
by Tenant's failure to perform his obligations  under this Lease or which in the
ordinary  course of events  would be  likely  to result  therefrom;  plus (5) at
Landlord's  election,  such  other  amounts  in  addition  to or in  lieu of the
foregoing as may be permitted from tie to time by applicable  law. Upon any such
re-entry  Landlord  shall  have  the  right  to  make  any  reasonable  repairs,
alterations  or  modifications  to the  Premises,  which  Landlord  in its  sole
discretion deems  reasonable and necessary.  As used in (1) above, the "worth at
the time of award" is computed  by allowing  interest at the rate of ten percent
(10%) per annum  from the date of  default.  As used in (2) and (3)  above,  the
"worth at the time of award"  is  computed  by  discounting  such  amount at the
discount  rate of the U.S.  Federal  Reserve  Bank at the time of award plus one
percent (1%).

Remedies of Landlord  contained in this Lease shall be 


                                       10
<PAGE>

construed and held to be cumulative, and Landlord shall have the right to pursue
any one or all of such  remedies  or any other  remedy  or  relief  which may be
provided by law. No waiver of any default of Tenant  hereunder  shall be implied
from any  acceptance by Landlord of any rent or other  payments due hereunder or
any  omission by Landlord to take any action on account of such  default if such
default  persists or is repeated,  and no express  waiver shall affect  defaults
other than as specified  in said waiver.  The consent or approval of Landlord to
or of any act by Tenant  requiring  Landlord's  consent or approval shall not be
deemed to waive or render  unnecessary  Landlord's  consent or approval to or of
any subsequent similar acts by Tenant.

21. EMINENT DOMAIN.  If more than  twenty-five  percent (25%) of the Premises is
taken or appropriated  by any public or  quasi-public  authority under powers of
eminent  domain,  either  party  hereto  shall have the right at its option,  to
terminate this Lease. If less than twenty-five  percent (25%) of the Premises is
taken (or neither  party  elects to  terminate  as above,  provided if more than
twenty-five  percent (25%) is taken),  the Lease shall continue,  but the rental
thereafter to be paid shall be equitably reduced. If any part of the building of
which the Premises are a party is so taken or  appropriated,  whether or not any
part of the Premises is involved, Landlord shall be entitled to the entire award
and  compensation  for the  taking  which  is paid  or  made  by the  public  or
quasi-public agency, and Tenant shall have no claim against said award.

22.  STATEMENT TO LENDER.  Tenant shall at any time and from time to time,  upon
not less  than ten (10)  days  prior  written  notice  from  Landlord,  execute,
acknowledge, and deliver to Landlord a statement in writing, (a) certifying that
this Lease is unmodified and in full force and effect (or, if modified,  stating
the nature of such  modifications and certifying that this Lease as so modified,
is in full force and effect), and the date to which the rental and other charges
are paid in  advance,  if any,  and (b)  acknowledging  that  there are not,  to
Tenant's knowledge,  any uncured defaults on the part of the Landlord hereunder,
or specifying such defaults if any are claimed. Any such statement may be relied
upon by any  prospective  purchaser or encumbrancer of all or any portion of the
real property of which the Premises are a part.

23. PARKING. Tenant shall have the right to use, in common with other tenants or
occupants of the building, parking facilities,  provided by Landlord for Tenants
of The Landmark,  subject to the rules and regulations  established by Landlord.
Said parking  shall be at no expense to the Tenant  unless a tax, fee or levy is
imposed  directly  or  indirectly  by  a  Federal,  State  or  local  agency  or
jurisdiction for parking. If such a tax, fee or levy is imposed tenant agrees to
pay 

                                       11
<PAGE>

its portion of said fee as reasonably determined by the Landlord.

by Tenant of any  provision of this Lease,  other than the failure of the Tenant
to pay the particular rental so accepted,  regardless of Landlord's knowledge of
such preceding breach at the time of the acceptance of such rent.

25.3  Notices.  All notices and demands which may or are required to be given by

removed or cleaned up without  regard to whether  the party  required to pay for
the  "clean up" caused the  contamination,  owned the  property  at the time the
contamination occurred or even knew about the contamination. Some items, such as

     the  cost of  installation  and  repair  shall  be  divided  among  tenants
     currently being served by said cables.

     29.5 Not all  existing  telephone  rooms/punchdown  boards  are  permanent.
     Tenant and his contractor must verify  location of termination  points with
     the Landlord prior to installation.

Except as herein  modified all the terms and  conditions  set forth in the Lease
shall remain unchanged.

                       EMPLOYMENT & NON-COMPETE AGREEMENT


         This Agreement is made as of July 22, 1997,  between  Infodata  Systems
Inc., a Virginia  Corporation (the "Company"),  AMBIA Corporation,  a California
corporation ("AMBIA"), and Razi Mohiuddin ("Employee"). The Company and Employee
agree as follows:

         1.  Employment.  The  Company and AMBIA  agree to employ  Employee  and
Employee  accepts such  employment by the Company upon the terms and  conditions
set  forth  in this  Agreement,  for the  period  beginning  on the date of this
agreement and ending upon  termination  pursuant to paragraph 4 (the "Employment
Period"). During the Employment Period, employee shall serve: (a) the Company as
Vice President, West Coast Operations, and shall be responsible for (i) vertical
integration of the Company's Business into the pharmaceutical industry, and (ii)
the Company's  United States  consulting and integration  activities west of the
Mississippi River; and (b) AMBIA as Executive Vice President,  provided that and
for so long as AMBIA remains a subsidiary of the Company. Employee shall perform
his  duties  in  California,  unless  the  parties  mutually  agree  in  writing
otherwise.

         2.  Compensation  and  Benefits.  In  consideration  for  the  valuable
services to be rendered by Employee and for his agreement not to compete against
the Company as described in paragraph 5, the Company  hereby  agrees that during
the two years of the  Employment  Period,  the Company will pay employee a gross
salary at the annual rate of $110,000 per annum (the "Base Salary").  Employee's
Base  Salary may be  adjusted  annually  based on an annual  performance  salary
review as determined in the  reasonable  discretion of the Board of Directors of
the Company (the "Board");  provided,  however,  that employee's Base Salary may
not be adjusted to an amount which is less than the initial  Base Salary  amount
stated above.  Employee will also be eligible for participation in the Company's
incentive  compensation  program, 1995 Stock Option Plan, as amended, 1997 Stock
Purchase Plan and other employee  benefit and welfare benefit plans and programs
provided to other  employees of the Company from time to time. The Company shall
reimburse (or pay on his behalf) reasonable expenses incurred by Employee at the
request of, or on behalf of, the Company in the performance of Employee's duties
pursuant to this  Agreement  and in  accordance  with the  Company's  employment
policies.

         3. Services.  During the Employment  Period,  Employee agrees to devote
his best efforts and substantially all of his business time and attention to the
business affairs of the Company (except for reasonable  vacation periods subject
to the  reasonable  approval  of the Board of  reasonable  periods of illness or
other incapacity).  During the Employment Period, Employee agrees to render such
services  as the Board  may from  time to time  direct.  During  the  Employment
Period,  Employee agrees that he will not, except with the prior written consent
of the Board or President of the Company,  become engaged in or render  services
for any business other than the Business of the Company; provided, however, that
Employee  may  purchase  or  otherwise  acquire  up to (but not more  than) five
percent (5%) of any class of securities of any enterprise (but without otherwise
actively  participating in the activities of such enterprise) and up to (but not
more than one percent (1%) of any class of  securities  of any  enterprise  (but
without otherwise  actively  participating in the activities of such enterprise)
if such securities are listed on any national or regional securities exchange or
have been registered under Section 12(g) of the Securities Exchange Act of 1934,
as amended.  Notwithstanding  anything to the  contrary in this  Agreement,  the
Board and the  President of the Company  hereby  agree that  Employee may render
services for the  businesses  listed on Exhibit "A" hereto so long as Employee's
services  to such  other  businesses  does not  unreasonably  interfere,  in the
opinion  of  the  Board  of  the  President  of  the  Company,  with  Employee's
performance of his duties to the Company or the Company's Business.


<PAGE>

         4.  Termination.  The Employment  Period will continue from the date of
this Agreement for a period of twenty-four  (24) months,  unless extended by the
mutual agreement of the Company and Employee or unless terminated earlier by (a)
Employee's  death or permanent  disability  which renders the Employee unable to
perform his duties  hereunder  (as  determined  by the provider of the Company's
disability  insurance  under the  terms of the  Company's  disability  insurance
policy), (b) by Employee's  resignation upon prior written notice to the Company
of sixty (60) days or (c) the Board for  Cause.  For  purpose of this  paragraph
"Cause"  shall mean (i) the  failure or refusal of Employee to follow the lawful
directives  of the  Board or a  designee  (except  due to  sickness,  injury  or
disabilities),  which  directives are  substantially  consistent with Employee's
employment  responsibilities  hereunder,  (ii) gross  inattention to duty or any
other  willful,  reckless  or  grossly  negligent  act (or  omission  to act) by
Employee, which, in the good faith judgment of the Board, materially injures the
Company,  including  the failure to follow the  policies and  procedures  of the
Company,  (iii) a material  breach of this  Agreement by  Employee,  or (iv) the
commission by Employee of a felony or other crime  involving  moral turpitude or
the  commission  by  Employee  of an act of  financial  dishonesty  against  the
Company.

         5.       Noncompetition.

                  (a) The non-compete  provisions of this paragraph 5 will apply
to  Employee  during  the  Employment  Period  and  upon the  expiration  of the
Employment  Period or the earlier  termination  of the  Employment  Period under
paragraphs  4(b) or 4(c) above.  In the event the  Employment  Period is earlier
terminated  without  Cause,  then  no part of this  paragraph  5 will  apply  to
Employee.

                  (b) Employee  recognizes  and  acknowledges  that by virtue of
accepting  employment  hereunder,  Employee  will  acquire  valuable  knowledge,
enhance his  professional  skills and experience,  and learn  proprietary  trade
secrets and Confidential  Information (as hereinafter defined in Paragraph 6) of
the Company.  In  consideration  of the foregoing and this employment  contract,
Employee  agrees  that  during  the  Employment  Period  and for  two (2)  years
thereafter (the "Non-Compete Period"), Employee will not directly or indirectly:

                           (i)  except  in  connection  with  any  duties  as an
         employee of the  Company,  divert or attempt to divert any party who is
         or was an existing or prospective client, customer or supplier of AMBIA
         and/or  the  Company  within  the last 28  months  prior to the date of
         termination  from  engaging in business  with the Company or any of its
         Affiliates,  or provide  any  services  or products to or engage in any
         business that is competitive with Infodata's or AMBIA's Business;

                           (ii) during the one-year period immediately following
         the date of termination of employment under this Agreement, solicit for
         employment or encourage to leave their employment, in each case, either
         as an employee, agent or representative,  any person who was during the
         two-year period prior to such  solicitation or  encouragement  or is an
         officer, employee, agent or representative of AMBIA or the Company;

                           (iii)  disturb,  or attempt to disturb,  any business
         relationship between any third party and AMBIA or the Company; or


                                      - 2 -


<PAGE>

                           (iv) make any statement to any third party, including
         the press or media, which is false or defamatory regarding either AMBIA
         or the Company.

Employee  and the  Company  each agree that the  restraints  imposed  under this
paragraph 5 are reasonable and not unduly harsh or oppressive.

                  (c)  If,  at the  time  of  enforcement  of any  provision  of
paragraph  5(b)  above,  any of the  provisions  of this  paragraph  5 shall  be
determined  to  be  invalid  or  unenforceable  by  reason  of  being  vague  or
unreasonable  as to duration,  area,  scope of activity or otherwise,  then this
paragraph shall be considered  divisible (with the other provisions to remain in
full force and effect) and the invalid or unenforceable  provisions shall become
and be deemed to be immediately  amended to include only such time,  area, scope
of activity and other restrictions,  as shall be determined to be reasonable and
enforceable by the court or other body having  jurisdiction over the matter, and
Employee expressly agrees that this Agreement, as so amended, shall be valid and
binding as though any invalid or  unenforceable  provision had not been included
herein.

                  (d) Since a material  purpose of this  Agreement is to protect
the Company's and AMBIA's  investment in the Employee and to secure the benefits
of his  background  and general  experience in the industry,  the parties hereto
agree and  acknowledge  that money damages may not be an adequate remedy for any
breach of the  provisions  of this  paragraph  5.  Therefore,  in the event of a
breach by Employee of any of the  provisions  of this  paragraph 5, the Company,
AMBIA or their  successors  or assigns  may,  in  addition  to other  rights and
remedies  existing  in their  favor  apply  to any  court  of law or  equity  of
competent  jurisdiction  for specific  performance  and/or  injunctive  or other
relief in order to enforce or prevent any  violations of the  provisions of this
Agreement.

         6.   Confidential   Information.   Employee   acknowledges   that   the
information,  observations, data and trade secrets (collectively,  "Confidential
Information")  obtained by him during the course of his  performance  under this
Agreement  concerning AMBIA's and the Company's Business are the property of the
AMBIA and/or the Company.  For purposes of this Agreement,  "trade secret" means
any method,  program or compilation  of information  which is used in AMBIA's or
the Company's Business,  including but not limited to: (a) techniques, plans and
materials  used by either  AMBIA or the  Company,  (b)  business  and  marketing
methods and strategies employed by either AMBIA or the Company, (c) all computer
hardware  and  software  developed or utilized by either AMBIA or the company in
its  Business  and (d) all  lists  of  past,  present  or  prospective  clients,
customers and suppliers of either AMBIA or the Company; provided,  however, that
such term  shall not  include  any such items  Employee  lawfully  used,  owned,
possessed  or  developed  prior to the  formation  of AMBIA  and was  using  for
purposes  unrelated  to AMBIA's  Business  at any time prior to the date of this
Agreement.  Employee agrees that he will not disclose to any unauthorized Person
or use for his own  account  any of such  Confidential  Information  without the
Board's  written  consent,  unless  and to the  extent  that the  aforementioned
matters  becoming  generally  known to and available for use by the public other
than as a result of  Employee's  acts or  omissions  to act or  become  known to
Employee  lawfully  outside the scope of his  employment  under this  Agreement.
Employee  agrees to deliver to the Company at the termination of his employment,
or at any other time the Company  may  request,  all  memoranda,  notes,  plans,
records,  reports  and other  documents  (and  copies  thereof)  relating to the
Business of either AMBIA or the Company  which he may then possess or have under
his control.

         7.  Notices.  Any notice  provided  for in this  Agreement  shall be in
writing and shall be either

                       EMPLOYMENT & NON-COMPETE AGREEMENT

This Agreement is made as of October 11, 1995 between  Infodata  Systems Inc., a

Company and Employee agree as follows:

1.  Employment.  The Company agrees to employ Employee and Employee accepts such
employment  by the  Company  upon the  terms  and  conditions  set forth in this
Agreement,  for the period  beginning on the date of this  Agreement  and ending
upon termination pursuant to paragraph 4 (the "Employment Period").

2.  Compensation.  In consideration  for the valuable services to be rendered by
Employee and for his agreement  not to compete  against the Company as described
in  paragraph  5, the  Company  hereby  agrees  that during the two years of the
Employment  Period,  the Company  will pay Employee a gross salary at the annual
rate of $125,000 per annum (the "Base  Salary").  Employee's  Base Salary may be
adjusted annually based on an annual  performance salary review as determined in
the  reasonable  discretion  of the  Board  of  Directors  of the  Company  (the
"Board");  provided, however, that Employee's Base Salary may not be adjusted to
an amount  which is less than the  initial  base  salary  amount  stated  above.
Employee  will also be eligible for  participation  in the  Company's  incentive

Management  Committee,  all for such time as may be determined in the reasonable
discretion of the Board.

3. Services.  During the Employment  Period,  Employee agrees to devote his best
efforts and substantially all of his business time and attention to the business
affairs of the Company  (except for reasonable  vacation  periods subject to the
reasonable  approval  of the Board or  reasonable  periods  of  illness or other
incapacity).  During  the  Employment  Period,  Employee  agrees to render  such
services  as the Board  may from  time to time  direct.  During  the  Employment

Mr. James Ungerleider
7210 Marlin Drive
Alexandria, VA 22307

Dear Jim,

We are  pleased  to offer you the  position  of  President  and Chief  Executive
Officer of Infodata Systems Inc. In this position,  you will report to the Board
of Directors and its Chairman, Richard T. Bueschel.

As the  Company's  Chief  Executive  Officer,  your  annual  base salary will be
$200,000,  payable  monthly.  You will  participate in an annual incentive bonus
plan with a target bonus  potential of up to fifty percent of base salary.  This
bonus will be based upon mutually agreed performance  achievements  against both
personal  management  objectives  for the year and  selected  company  financial
performance  measures.  We will agree on these measures  during your first sixty
days of employment. In recognition of your leadership role at Infodata, you will
be awarded  options to acquire  250,000  shares of stock at a price of $9.50 per
share,  which will vest to you as follows:  75,000 options upon employment,  two
increments of 50,000 on the first and second  anniversaries  of employment,  and
the remaining 75,000 options on the third  anniversary of your employment.  This
vesting is contingent  only on your  continued  employment  on those  respective
dates.

The level of your salary and bonus will be reviewed  annually by the Board.  You
will, of course,  be eligible to participate in the Company's Stock Option grant
program  going  forward.  The amounts of any such  future  grants are subject to
approval of the Board of  Directors.  In  addition,  you will  receive a $50,000
hiring  bonus  to be paid on  January  2,  1998.  You  will  participate  in the
Company's  benefit  plans  available to our other senior  executives,  including
health insurance, life insurance, and other programs.  Infodata will provide you
with a life  insurance  policy with a death benefit equal to two times your base
salary, and disability coverage equal to sixty (60) percent of your base salary.

It is understood that your employment at Infodata is  terminable-at-will  and is
not for any definite term. However,  Infodata agrees that in the event that your
employment is terminated by the Company, other than for cause, you will continue
to be paid  your base  salary in  monthly  increments  for a period of  eighteen
months, along with your various insurance benefits. A termination for cause will
be defined as a termination  by the Company of your  employment  due to (a) your
willful  disregard  and  failure to perform the duties for which  employed  (not
including

Mr. James Ungerleider

failure to perform due to a disability
entitling  you to  disability  benefits) so as to result in material harm to the
Company,  or (b) your  indictment for a crime  constituting  a felony  involving
moral turpitude and resulting in material harm to the Company.

Should  you  begin  employment   elsewhere  with  a  new  employer  during  this
eighteen-month  period,  these Infodata  benefits (but not Salary  Continuation)
will  cease  upon your  eligibility  for the new  employer's  similar  programs.
Further, if during your first twelve months of employment at Infodata,  I am not
Chairman  of the  Board,  and  during  that same  twelve  month  period  you are
terminated  other than for cause,  the above salary and benefit  provisions will
apply to a twenty-four month period following your departure.

Please confirm your  acceptance of this offer and its terms by signing below and
returning a signed copy of this agreement to me.

As I am sure  you know  already  from the  time we have  been  together,  we are
excited  about your coming to Infodata  and leading the next steps in our growth
and  business  performance.  On behalf of our entire  board,  we look forward to
working together in the years ahead.

Sincerely,


/s/ Richard T. Bueschel

3. WCMA LOANS

(a) ACTIVATION DATE. Provided that: (i) the Commitment Expiration Date shall not
then have occurred,  and (ii) Customer shall have subscribed to the WCMA Program
and its subscription to the WCMA Program shall then be in effect, the Activation
Date shall occur on or promptly after the date, following the acceptance of this
Loan Agreement by MLBFS at its office in Chicago,  Illinois,  upon which each of
the  General  Funding  Conditions  shall  have  been  met  or  satisfied  to the
reasonable  satisfaction  of MLBFS.  No  activation by MLBFS of the WCMA Line of
Credit for a nominal amount shall be deemed evidence of the  satisfaction of any
of the  conditions  herein  set  forth,  or a  waiver  of any  of the  terms  or
conditions hereof.  Customer hereby authorizes MLBFS to pay out of and charge to
Customer's  WCMA Account on the Activation  Date all amounts  necessary to fully
pay off any bank or other  financial  institution  having a lien upon any of the
Collateral other than a Permitted Lien.

(b) WCMA LOANS.  Subject to the terms and conditions  hereof,  during the period
from and after the  Activation  Date to the Maturity  Date:  (i) MLBFS will make
WCMA Loans to Customer in such amounts as Customer may from time to time request
in accordance with the terms hereof, up to an aggregate  outstanding  amount not
to exceed the Maximum WCMA Line of Credit,  and (ii) Customer may repay any WCMA
Loans in whole or in part at any time without premium or penalty,  and request a
reborrowing  of amounts repaid on a revolving  basis.  Customer may request WCMA
Loans by use of WCMA Checks, FTS, Visa(R) charges, wire transfers, or such other
means of access to the WCMA Line of  Credit as may be  permitted  by MLBFS  from
time to time; it being  understood that so long as the WCMA Line of Credit shall
be in  effect,  any charge or debit to the WCMA  Account  which but for the WCMA
Line of  Credit  would  under  the  terms of the  WCMA  Agreement  result  in an
overdraft, shall be deemed a request by Customer for a WCMA Loan.

(c) CONDITIONS OF WCMA LOANS.  Notwithstanding the foregoing, MLBFS shall not be
obligated to make any WCMA Loan, and may without notice refuse to honor any such
request by Customer,  if at the time of receipt by MLBFS of Customer's  request:
(i) the making of such WCMA Loan would cause the Maximum  WCMA Line of Credit to
be exceeded;  or (ii) the Maturity Date shall have occurred, or the WCMA Line of
Credit shall have otherwise been terminated in accordance with the terms hereof;
or (iii) Customer's subscription to the WCMA Program shall have been terminated;
or (iv) an event shall have occurred and is  continuing  which shall have caused
any of the General  Funding  Conditions  to not then be met or  satisfied to the
reasonable satisfaction of MLBFS. The making by MLBFS of any WCMA Loan at a time
when any one or more of said conditions shall not have been met shall not in any
event be construed as a waiver of said  condition or  conditions or of any Event
of  Default,  and  shall  not  prevent  MLBFS at any time  thereafter  while any
conditions  shall  not have  been met from  refusing  to honor  any  request  by
Customer for a WCMA Loan.

God or other  cause  beyond the  reasonable  control of MLBFS,  MLPF&S or any of
their  affiliates  unless  directly  arising out of the willful  wrongful act or
active gross  negligence of MLBFS. In no event shall MLBFS be liable to Customer
or any other party for any incidental or consequential  damages arising from any
act or omission by MLBFS,  MLPF&S or any of their  affiliates in connection with
the WCMA Line of Credit or this Loan Agreement.

(e) INTEREST.  The WCMA Loan Balance  shall bear interest at the Interest  Rate.
Interest shall be computed for the actual number of days elapsed on the basis of
a year consisting of 360 days.  Notwithstanding any provision to the contrary in
this  Agreement  or any of the  Additional  Agreements,  no  provision  of  this
Agreement  or any of the  Additional  Agreements  should  require the payment or
permit the  collection of any amount in excess of the maximum amount of interest
permitted to be charged by law ("Excess  Interest").  If any Excess  Interest is
provided for, or is  adjudicated as being provided for, in this Agreement or any
of the Additional  Agreements,  then: (a) Customer shall not be obligated to pay
any Excess  Interest;  and (b) any Excess  Interest that MLBFS may have received
hereunder  or under any of the  Additional  Agreements  shall,  at the option of
MLBFS,  be: (i) applied as a credit  against the then unpaid balance of the WCMA
Line of Credit,  (iii) any  combination  of the  foregoing.  Except as otherwise
provided  herein,  accrued and unpaid interest on the WCMA Loan Balance shall be
payable monthly on the last Business Day of each calendar month, commencing with
the last Business Day of the calendar month in which the  Activation  Date shall
occur.  Customer hereby  irrevocably  authorizes and directs MLPF&S to pay MLBFS
such  accrued  interest  from any  available  free  credit  balances in the WCMA
Account,  and if such available free credit balances are insufficient to satisfy
any interest  payment due, to liquidate any  investments  in the Money  Accounts
(other than any  investments  constituting  any Minimum Money  Accounts  Balance
under the WCMA Directed  Reserve program) in an amount up to the balance of such
accrued interest, and pay to MLBFS the available proceeds on account thereof. If
available free credit balances in the WCMA Account and available proceeds of the
Money Accounts are  insufficient to pay the entire balance of accrued  interest,
and Customer  otherwise  fails to make such payment when due,  MLBFS may, in its
sole  discretion,  make a WCMA Loan in an amount  equal to the  balance  of such
accrued  interest and pay the proceeds of such WCMA Loan to itself on account of
such  interest.  The amount of any such WCMA Loan will be added to the WCMA Loan
Balance.  If MLBFS  declines  to  extend a WCMA  Loan to  Customer  under  these
circumstances,  Customer  hereby  authorizes and directs MLPF&S to make all such
interest payments to MLBFS from any Minimum Money Accounts Balance.  If there is
no Minimum  Accounts  Balance,  or it is  insufficient to pay all such interest,
MLBFS will invoice Customer for payment of the balance of the accrued  interest,
and Customer shall pay such interest as directed by MLBFS within 5 Business Days
of receipt of such invoice.

(f)  PAYMENTS.  All payments  required or permitted to be made  pursuant to this
Loan  Agreement  shall be made in  lawful  money of the  United  States.  Unless
otherwise directed by MLBFS, payments on account of the WCMA Loan Balance may be
made by the delivery of checks (other than WCMA  Checks),  or by means of FTS or
wire transfer of funds (other than funds from the WCMA Line of Credit) to MLPF&S
for credit to  Customer's  WCMA  Account.  Notwithstanding  anything in the WCMA
Agreement to the contrary,  Customer hereby  irrevocably  authorizes and directs
MLPF&S to apply  available  free  credit  balances  in the WCMA  Account  to the
repayment of the WCMA Loan Balance prior to  application  for any other purpose.
Payments to MLBFS from funds in the WCMA  Account  shall be deemed to be made by
Customer  upon the same  basis  and  schedule  as funds are made  available  for
investment  in the  Money  Accounts  in  accordance  with the  terms of the WCMA
Agreement.  All funds  received by MLBFS from MLPF&S  pursuant to the  aforesaid
authorization  shall be applied by MLBFS to repayment of the WCMA Loan  Balance.
The acceptance by or on behalf of MLBFS of a check or other payment for a lesser
amount  than  shall be due  from  Customer,  regardless  of any  endorsement  or
statement  thereon or transmitted  therewith,  shall not be deemed an accord and
satisfaction  or anything  other than a payment on account,  and MLBFS or anyone
acting on  behalf  of MLBFS  may  accept  such  check or other  payment  without
prejudice  to the  rights of MLBFS to recover  the  balance  actually  due or to
pursue any other remedy under this Loan  Agreement  or  applicable  law for such
balance.  All checks  accepted by or on behalf of MLBFS in  connection  with the
WCMA Line of Credit are subject to final collection.


                                      - 4 -

(g) EXCEEDING  THE MAXIMUM WCMA LINE OF CREDIT.  In the event that the WCMA Loan
Balance shall at any time exceed the Maximum WCMA Line of Credit, Customer shall
within 1  Business  Day of the  first to occur of (i) any  request  or demand of
MLBFS,  or (ii)  receipt by Customer of a statement  from MLPF&S  showing a WCMA
Loan  Balance in excess of the Maximum WCMA Line of Credit,  deposit  sufficient
funds into the WCMA  Account to reduce the WCMA Loan  Balance  below the Maximum
WCMA Line of Credit.

(h) LINE FEE; EXTENSIONS. (i) In consideration of the extension of the WCMA Line
of Credit by MLBFS to Customer during the period from the Activation Date to the
Maturity Date, Customer has paid or shall pay the Line Fee to MLBFS. If such fee
has not heretofore been paid by Customer,  Customer hereby  authorizes MLBFS, at
its option,  to either cause said fee to be paid with a WCMA Loan which is added
to the WCMA Loan  Balance,  or  invoice  Customer  for said fee (in which  event
Customer  shall  pay said fee  within 5  Business  Days  after  receipt  of such
invoice).  No delay in the  Activation  Date,  howsoever  caused,  shall entitle
Customer to any rebate or reduction in the Line Fee or extension of the Maturity
Date.

(ii) In the event MLBFS and Customer,  in their respective sole discretion agree
to renew the WCMA Line of Credit  beyond the  current  Maturity  Date,  Customer
agrees to pay a renewal Line Fee or Line Fees (if the Maturity  Date is extended
for more than one 12-month  period),  in the amount per 12-month period or other
applicable  period then set forth in the writing  signed by MLBFS which  extends
the Maturity Date; it being  understood  that any request by Customer for a WCMA
Loan or failure of  Customer  to pay any WCMA Loan  Balance  outstanding  on the
immediately  prior  Maturity  Date,  after the  receipt by Customer of a writing
signed by MLBFS  extending  the  Maturity  Date,  shall be  deemed a consent  by
Customer to both the renewal Line Fees and the new Maturity  Date. If no renewal
Line Fees are set forth in the writing  signed by MLBFS  extending  the Maturity
Date,  the renewal Line Fee for each  12-month  period shall be deemed to be the
same as the immediately  preceding periodic Line Fee. Each such renewal Line Fee
may,  at the option of MLBFS,  either be paid with a WCMA Loan which is added to
the WCMA Loan Balance or invoiced to Customer,  as aforesaid,  on or at any time
after the first Business Day of the first Business Day of the first month of the
12-month period for which such fee is due.

(i)  STATEMENTS.  MLPF&S will include in each monthly  statement it issues under
the WCMA  Program  information  with  respect  to WCMA  Loans  and the WCMA Loan
Balance.  Any questions that Customer may have with respect to such  information
should be directed to MLBFS;  and any questions with respect to any other matter
in such  statements or about or affecting the WCMA Program should be directed to
MLPF&S.

(j) USE OF LOAN PROCEEDS;  SECURITIES  TRANSACTIONS.  On the Activation  Date, a
WCMA will be made to pay any  indebtedness  of Customer to a third party secured
by all or any part of the Collateral.  The proceeds of each subsequent WCMA Loan
shall be used by Customer  solely for working  capital in the ordinary course of
its  business,  or, with the prior  written  consent of MLBFS,  for other lawful
business purposes of Customer not prohibited hereby.  Customer agrees that under
no circumstances  will funds borrowed from MLBFS through the WCMA Line of Credit
be  used:  (i)  for  personal,  family  or  household  purposes  of  any  person
whatsoever, (ii) to purchase, carry or trade in securities,  including shares of
the Money Accounts, or (iii) to repay debt incurred to purchase,  carry or trade
in securities;  nor will any such funds be remitted,  directly or indirectly, to
an account of Customer with MLPF&S or any other broker or dealer in  securities,
by WCMA Check, check, FTS, wire transfer, or otherwise.

4. REPRESENTATIONS AND WARRANTIES

periods  then ended;  and since the most recent date  covered by such  financial
statements,  there has been no  material  adverse  change in any such  financial
condition or operation.

(g)  LITIGATION.  No litigation,  arbitration,  administrative  or  governmental

Additional  Agreements,  the  financial  condition of Customer or the  continued
operations of Customer.

(h) TAX  RETURNS.  All  federal,  state  and  local  tax  returns,  reports  and
statements required to be filed by Customer have been filed with the appropriate
governmental agencies and all taxes due and payable by Customer have been timely

Customer, or the continued operations of Customer).

(i) COLLATERAL LOCATION. All of the tangible Collateral is located at a Location

Each of the foregoing representations and warranties are continuing and shall be
deemed remade by Customer concurrently with each request for a WCMA Loan.

                                     - 7 -
<PAGE>

(c)  PERFORMANCE OF  OBLIGATIONS.  Customer shall perform all of its obligations
owing on account of or with respect to the Collateral;  it being understood that
nothing herein, and no action or inaction by MLBFS, under this Loan Agreement or
otherwise,  shall be deemed an  assumption  by MLBFS of any of  Customer's  said
obligations.

(d) SALES AND  COLLECTIONS.  So long as no Event of Default  shall have occurred
and is continuing, Customer may in the ordinary course of its business: (i) sell
any  inventory  normally  held by  Customer  for sale,  (ii) use or consume  any
materials  and supplies  normally held by Customer for use or  consumption,  and
(iii) collect all of its Accounts.  Customer shall take such action with respect
to protection of its inventory and other  Collateral  and the  collection of its
Accounts as MLBFS may from time to time reasonably request.

(e) ACCOUNT SCHEDULES.  Upon the request of MLBFS, made now or at any reasonable
time or times  hereafter,  Customer  shall deliver to MLBFS,  in addition to the
other information required hereunder,  a schedule identifying,  for each Account
and all Chattel  Paper  subject to MLBFS'  security  interests  hereunder,  each
Account  Debtor by name and address and amount,  invoice or contract  number and
date of  each  invoice  or  contract.  Customer  shall  furnish  to  MLBFS  such
additional  information with respect to the Collateral,  and amounts received by
Customer as proceeds  of any of the  Collateral,  as MLBFS may from time to time
reasonably request.

(f) ALTERATIONS AND MAINTENANCE. Except upon the prior written consent of MLBFS,
Customer  shall  make  or  permit  any  material  alterations  to  any  tangible
Collateral which might materially  reduce or impair its market value or utility.
Customer  shall at all times keep the tangible  Collateral in good condition and
repair and shall pay or cause to be paid all obligations arising from the repair
and maintenance of such Collateral,  as well as all obligations  being contested
by Customer in good faith by appropriate proceedings.

(g) LOCATION. Except for movements required in the ordinary course of Customer's
business, Customer shall give MLBFS 30 days' prior written notice of the placing
at or movement of any tangible  Collateral to any location other than a Location
of Tangible Collateral.  In no event shall Customer cause or permit any material
tangible  Collateral  to be removed from the United  States  without the express
prior written consent of MLBFS.

(h)  INSURANCE.  Customer  shall insure all of the tangible  Collateral  under a
policy or policies of physical  damage  insurance  providing that losses will be
payable to MLBFS as its interests may appear pursuant to a Lender's Loss Payable
Endorsement and containing such other  provisions as may be reasonably  required
by MLBFS.  Customer  shall further  provide and maintain a policy or policies of
comprehensive  public  liability  insurance  naming MLBFS as an additional party
insured.  Customer shall maintain such other insurance as may be required by law
or is  customarily  maintained  by companies in a similar  business or otherwise
reasonably  required by MLBFS.  All such insurance shall provide that MLBFS will
receive  not less than 10 days prior  written  notice of any  cancellation,  and
shall otherwise be in form and amount and with an insurer or insurers reasonably
acceptable to MLBFS.  Customer shall furnish MLBFS with a copy or certificate of
each such policy or policies and, prior to any expiration or cancellation,  each
renewal or replacement thereof.

(i) EVENT OF LOSS.  Customer shall at its expense promptly repair all repairable
damage to any tangible Collateral.  In the event that any tangible Collateral is
damaged  beyond repair,  lost,  totally  destroyed or confiscated  (an "Event of
Loss") and such Collateral had a value prior to such Event of Loss of $25,000.00
or more,  then,  on or  before  the  first to  occur  of (i) 90 days  after  the
occurrence  of such Event of Loss,  or (ii) 10  Business  Days after the date on
which either  Customer or MLBFS shall receive any proceeds of either Customer or
MLBFS that it  disclaims  liability  in respect of such Event of Loss,  Customer
shall, at Customer's option, either replace the Collateral subject to such Event
of Loss with comparable  Collateral free of all liens other than Permitted Liens
(in which event  Customer shall be entitled to utilize the proceeds of insurance
on  account of such  Event of Loss for such  purpose,  and may retain any excess
proceeds of such  insurance),  or consent to a reduction the WCMA Line of Credit
in an amount equal to the actual cash value of such  Collateral as determined by
either  the  applicable   insurance   company's  payment  (plus  any  applicable
deductible)  or,  in  absence  of  insurance  company  payment,   as  reasonably
determined by 


                                     - 8 -

<PAGE>

MLBFS. Notwithstanding the foregoing, if at the time of occurrence of such Event
of Loss or any  time  thereafter  prior to  replacement  or line  reduction,  as
aforesaid, an Event of Default shall occur hereunder, then MLBFS may at its sole
option, exercisable at any time while such Event of Default shall be continuing,
require  Customer to either replace such  Collateral or, on its own volition and
without the consent of Customer, reduce the WCMA Line of Credit, as aforesaid.

(j) NOTICE OF CERTAIN EVENTS.  Customer shall give MLBFS immediate notice of any
attachment,  lien, judicial process, encumbrance or claim affecting or involving
$25,000.00 or more of the Collateral.

(k)  INDEMNIFICATION.  Customer shall indemnify,  defend and save MLBFS harmless
from and against any and all claims,  liabilities,  losses,  costs and  expenses
(including, without limitation,  reasonable attorneys' fees and expenses) of any
nature whatsoever which may be asserted against or incurred by MLBFS arising out
of or in any manner occasioned by (i) the ownership, collection, possession, use
or operation of any  Collateral,  or (ii) any failure by Customer to perform any
of its obligations hereunder;  excluding,  however, from said indemnity any such
claims,  liabilities,  etc.  arising directly out of the willful wrongful act or
active gross negligence of MLBFS. This indemnity shall survive the expiration or
termination of this Loan  Agreement as to all matters  arising or accruing prior
to such expiration or termination.

8. EVENTS OF DEFAULT

The  occurrence  of any of the  following  events shall  constitute an "Event of
Default" under this Loan Agreement:

(a) FAILURE TO PAY. Customer shall fail to pay to MLBFS or deposit into the WCMA
Account when due any amount owing or required to be deposited by Customer  under
this Loan Agreement,  or shall fail to pay when due any other  Obligations,  and
any such  failure  shall  continue for more than 5 Business  Days after  written
notice thereof shall have been given by MLBFS to Customer.

(b) FAILURE TO PERFORM.  Customer shall default in the performance or observance
of any covenant or  agreement on its part to be performed or observed  under the
Loan Agreement or any of the Additional Agreements (not constituting an Event of
Default under any other clause of this Section), and such default shall continue
unremedied  for 10 Business  Days after written  notice  thereof shall have been
given by MLBFS to Customer.

contained in this Loan  Agreement or any of the Additional  Agreements  shall at
any time prove to have been incorrect in any material respect when made.

shall occur under the terms of any other agreement,  instrument or document with
or intended for the benefit of MLBFS, MLPF&S or any of their affiliates, and any
required  notice shall have been given and  required  passage of time shall have
elapsed.

(e)  BANKRUPTCY,  ETC.  A  proceeding  under  any  bankruptcy,   reorganization,
arrangement,  insolvency,  readjustment of debt or  receivership  law or statute
shall be filed  by  Customer,  or any  such  proceeding  shall be filed  against
Customer and shall not be dismissed or withdrawn within 60 days after filing, or
Customer  shall make an  assignment  for the benefit of  creditors,  or Customer
shall  become  insolvent  or  generally  fail to pay,  or admit in  writing  its
inability to pay, its debts as they become due.

(f)  MATERIAL  IMPAIRMENT.  Any event shall occur which shall  reasonably  cause
MLBFS to in good faith  believe that the prospect of payment or  performance  by
Customer has been materially impaired.

(g) ACCELERATION OF DEBT TO OTHER CREDITORS. Any event shall occur which results
in the  acceleration of the maturity of any  indebtedness of $100,000.00 or more
of Customer to another creditor under any indenture, agreement,  undertaking, or
otherwise.

<PAGE>

(h)  SEIZURE  OR ABUSE OF  COLLATERAL.  The  Collateral,  or any  material  part
thereof,  shall be or become  subject to any material  abuse or misuses,  or any

Business Days.

9.      REMEDIES

(a) REMEDIES UPON DEFAULT. Upon the occurrence and during the continuance of any
Event of Default,  MLBFS may at its sole option do any one or more or all of the
following,  at such time and in such  order as MLBFS may in its sole  discretion
choose:

(i) TERMINATION.  MLBFS may without notice terminate the WCMA Line of Credit and
all  obligations  to  provide  the WCMA Line of Credit or  otherwise  extend any
credit to or for the benefit of Customer;  and upon any such  termination  MLBFS
shall be relieved of all such obligations.

(ii)  ACCELERATION.  MLBFS may declare the principal of and interest on the WCMA
Loan  Balance,  and all  other  Obligations  to be  forthwith  due and  payable,
whereupon  all  such  amounts  shall be  immediately  due and  payable,  without
presentment,  demand  for  payment,  protest  and notice of  protest,  notice of
dishonor, notice of acceleration, notice of intent to accelerate or other notice
or formality of any kind, all of which are hereby expressly waived.

(iii)  EXERCISE  RIGHTS OF SECURED  PARTY.  MLBFS may exercise any or all of the
remedies of a secured party under applicable law, including, but not limited to,
the UCC,  and any or all of its  other  rights  and  remedies  under  this  Loan
Agreement and the Additional Agreements.

(iv)  POSSESSION.  MLBFS may  require  Customer to make the  Collateral  and the
records pertaining to the Collateral available to MLBFS at a place designated by
MLBFS which is reasonably  convenient,  or may take possession of the Collateral
and the records  pertaining  to the  Collateral  without the use of any judicial
process and without any prior notice to Customer.

(v) SALE.  MLBFS may sell any or all of the Collateral at public or private sale
upon such terms and  conditions as MLBFS may reasonably  deem proper.  MLBFS may
purchase any  Collateral  at any such public sale.  The net proceeds of any such
public or private sale and all other amounts  actually  collected or received by
MLBFS pursuant  hereto,  after deducting all costs and expenses  incurred at any
time in the collection of the Obligations and in the protection,  collection and
sale of the Collateral, will be applied to the payment of the Obligations,  with
any remaining liable for any amount remaining unpaid after such application.

(vi) DELIVERY OF CASH, CHECKS, ETC. MLBFS may require Customer to forthwith upon
receipt,  transmit and deliver to MLBFS in the form received,  all cash, checks,
drafts and other instruments for the payment of money (properly endorsed,  where
required, so that such items may be collected by MLBFS) which may be received by
Customer at any time in full or partial payment of any  Collateral,  and require
that  Customer not commingle any such items which may be so received by Customer
with any other of its funds or property but instead hold them separate and apart
and in trust for MLBFS until delivery is made to MLBFS.

(vii) NOTIFICATION OF ACCOUNT DEBTORS.  MLBFS may notify any Account Debtor that
its Account or Chattel  Paper has been assigned to MLBFS and direct such Account

10.     MISCELLANEOUS

(a)  NON-WAIVER.  No  failure  or delay on the part of MLBFS is  exercising  any
right,  power or remedy pursuant to this Loan Agreement or any of the Additional
Agreements shall operate as a waiver thereof,  and no single or partial exercise
of any such right,  power or remedy shall preclude any other or further exercise
thereof, or the exercise of any other right, power or remedy. Neither any waiver
of any provision of this Loan Agreement or any of the Additional Agreements, nor
any consent to any departure by Customer  therefrom,  shall be effective  unless
the same shall be in writing and signed by MLBFS. Any waiver of any provision of
this Loan Agreement or any of the  Additional  Agreements and any consent to any
departure  by  Customer  from the  terms of this  Loan  Agreement  or any of the
Additional  Agreements shall be effective only in the specific  instance and for
the specific  purpose for which given.  Except as otherwise  expressly  provided
herein, no notice to or demand on Customer shall in any case entitle Customer to
any other or further notice or demand in similar or other circumstances.

(b)  DISCLOSURE.  Customer  hereby  irrevocably  authorize MLBFS and each of its
affiliates,  including without limitation MLPF&S, to at any time (whether or not
an Event of Default shall have occurred)  obtain from and disclose to each other
any and all financial and other information about Customer.

(c) COMMUNICATIONS.  All notices and other communications  required or permitted
hereunder shall be in writing, and shall be either delivered personally,  mailed
by postage  prepaid  certified mail or sent by express  overnight  courier or by
facsimile.  Such notices and  communications  shall be deemed to be given on the
date  of  personal  delivery,  facsimile  transmission  or  actual  delivery  of
certified  mail,  or one  Business  Day after  delivery to an express  overnight
courier.  Unless otherwise specified in a notice sent or delivered in accordance
with the terms  hereof,  notices and other  communications  in writing  shall be
given to the  parties  hereto  at their  respective  addresses  set forth at the
beginning of this Loan Agreement, or, in the case of facsimile transmission,  to
the parties at their respective regular facsimile telephone number.

(d) COSTS, EXPENSES AND TAXES. Customer shall upon demand pay or reimburse MLBFS
for:  (i) all  Uniform  Commercial  Code  filing  and search  fees and  expenses
incurred  by  MLBFS  in  connection   with  the   verification,   perfection  or
preservation  of  MLBFS'  rights  hereunder  or in the  Collateral  or any other
collateral for the Obligations; (ii) any and all stamp, transfer and other taxes
and fees payable or determined to be payable in connection  with the  execution,
delivery  and/or  recording  of this  Loan  Agreement  or any of the  Additional
Agreements; and (iii) all reasonable fees and out-of-pocket expenses (including,
but not limited to, reasonable fees and expenses of outside counsel) incurred by
MLBFS in connection with the 


                                     - 11 -

<PAGE>

enforcement of this Loan  Agreement or any of the  Additional  Agreements or the
protection  of  MLBFS'  rights  hereunder  or  thereunder,  excluding,  however,
salaries and expenses of MLBFS'  employees.  The  obligations  of Customer under
this  paragraph  shall  survive  the  expiration  or  termination  of this  Loan
Agreement and the discharge of the other Obligations.

(e) RIGHT TO PERFORM OBLIGATIONS.  If Customer shall fail to do any act or thing
which it has covenanted to do under this Loan Agreement or any representation or
warranty  on the part of  Customer  contained  in this Loan  Agreement  shall be
breached, MLBFS may, in its sole discretion, after 5 days written notice is sent
to Customer (or such lesser notice,  including no notice, as is reasonable under
the circumstances) do the same or cause it to be done or remedy any such breach,
and may expend its funds for such  purpose.  Any and all  reasonable  amounts so
expended by MLBFS shall be  repayable  to MLBFS by Customer  upon  demand,  with
interest at the  Interest  Rate during the period  from and  including  the date
funds are so expended by MLBFS to the date of  repayment,  and all such  amounts
shall be additional  Obligations.  The payment or performance by MLBFS of any of
Customer's  obligations hereunder shall not relieve Customer of said obligations
or of the  consequences  of having failed to pay or perform the same,  and shall
not waive or be deemed a cure of any Event of Default.

(f) LATE CHARGE.  Any payment  required to be made by Customer  pursuant to this
Loan  Agreement  not paid  within 10 days of the  applicable  due date  shall be
subject  to a late  charge in an amount  equal to the  lesser  of: (i) 5% of the
overdue  amount,  or (ii) the maximum amount  permitted by applicable  law. Such
late charge  shall be payable on demand,  or,  without  demand,  may in the sole
discretion of MLBFS be paid by a WCMA Loan and added to the WCMA Loan Balance in
the same manner as provided herein for accrued interest.

(g) FURTHER  ASSURANCES.  Customer agrees to do such further acts and things and
to execute  and deliver to MLBFS such  additional  agreements,  instruments  and
documents as MLBFS may  reasonably  require or deem  advisable to effectuate the
purposes  of  this  Loan  Agreement  or any  the  Additional  Agreements,  or to
establish,  perfect and maintain  MLBFS'  security  interests and liens upon the
Collateral, including, but not limited to: (i) executing financing statements or
amendments thereto when and as reasonably requested by MLBFS; and (ii) if in the
reasonable  judgment of MLBFS it is  required  by local law,  causing the owners
and/or mortgagees of the real property on which any Collateral may be located to
execute and deliver to MLBFS waivers or subordinations  reasonably  satisfactory
to MLBFS with respect to any rights in such Collateral.

(h) BINDING EFFECT.  This Loan Agreement and the Additional  Agreements shall be
binding  upon,  and shall  inure to the  benefit  of MLBFS,  Customer  and their
respective  successors and assigns.  Customer shall not assign any of its rights
or  delegate  any of its  obligations  under this Loan  Agreement  or any of the
Additional  Agreements  without  the prior  written  consent  of  MLBFS.  Unless
otherwise  expressly  agreed to in a writing  signed by MLBFS,  no such  consent
shall in any event relieve  Customer of any of its  obligations  under this Loan
Agreement or the Additional Agreements.

(i) HEADINGS. Captions and section and paragraph headings in this Loan Agreement
are  inserted  only as a  matter  of  convenience,  and  shall  not  affect  the
interpretation hereof.

(j) GOVERNING LAW. This Loan Agreement, and, unless otherwise expressly provided
therein, each of the Additional Agreements, shall be governed in all respects by
the laws of the State of Illinois.

(k) SEVERABILITY OF PROVISIONS.  Whenever possible,  each provision of this Loan
Agreement and the Additional  Agreements  shall be interpreted in such manner as
to be  effective  and valid under  applicable  law.  Any  provision of this Loan
Agreement  or  any  of  the  Additional   Agreements   which  is  prohibited  or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
only to the extent of such prohibition or unenforceability  without invalidating
the remaining provisions of this Loan Agreement and the Additional Agreements or
affecting  the  validity  or  enforceability  of  such  provision  in any  other
jurisdiction.

(l) TERM.  This Loan  Agreement  shall become  effective on the date accepted by
MLBFS at its office in Chicago, Illinois, and, subject to the terms hereof,shall
continue  in effect so long  thereafter  as the WCMA Line of Credit  shall be in

(m) INTEGRATION.  THIS LOAN AGREEMENT,  TOGETHER WITH THE ADDITIONAL AGREEMENTS,
CONSTITUTES THE ENTIRE UNDERSTANDING AND REPRESENTS THE FULL AND FINAL AGREEMENT
BETWEEN THE PARTIES WITH RESPECT TO THE SUBJECT  MATTER  HEREOF,  AND MAY NOT BE

OR  SUBSEQUENT  ORAL  AGREEMENTS  OF THE PARTIES.  THERE ARE NO  UNWRITTEN  ORAL

supersedes  and replaces any and all  proposals,  letters of intent and approval
and commitment letters from MLBFS to Customer, none of which shall be considered

of the  Additional  Agreements  to which  Customer is a party shall be effective
unless in a writing signed by both MLBFS and Customer.

(n)  JURISDICTION;  WAIVER.  CUSTOMER  ACKNOWLEDGES  THAT THIS LOAN AGREEMENT IS
BEING ACCEPTED BY MLBFS IN PARTIAL  CONSIDERATION OF MLBFS' RIGHT AND OPTION, IN
ITS  SOLE  DISCRETION,  TO  ENFORCE  THIS  LOAN  AGREEMENT  AND  THE  ADDITIONAL
AGREEMENTS  IN EITHER THE STATE OF ILLINOIS OR IN ANY OTHER  JURISDICTION  WHERE

TO JURISDICTION IN THE STATE OF ILLINOIS AND VENUE IN ANY STATE OR FEDERAL COURT
IN THE COUNTY OF COOK FOR SUCH PURPOSES,  AND CUSTOMER  WAIVES ANY ALL RIGHTS TO
