PROSPECTUS
                                2,100,000 Shares*

                              XYBERNAUT CORPORATION
   
      This Prospectus covers our sale of 2,100,000 shares of our common stock to
HSBC James Capel  Canada,  Inc.,  the Investor,  in  connection  with a proposed
financing arrangement whereby, we, at our option, may issue up to:

      o    $31,200,000  of  Common  Stock to the  Investor  over a twelve  month
           period based on weekly,  monthly or quarterly draw downs.  The number
           of shares to be issued for each  drawdown  will be based on the price
           per share equal to the lesser of (1) the average of the daily  volume
           weighted  average price of the Common Stock on NASDAQ SmallCap Market
           for a certain  number  of  consecutive  trading  days  preceding  the
           funding date of the draw down and (2) $8.00;

      o    $31,200,000  of Common Stock  issuable  upon exercise of an option we
           granted to the  Investor to purchase an  additional  amount of Common
           Stock up to the maximum amount of each draw down; and

      o    approximately  105,000  shares of Common Stock issuable upon exercise
           of  warrants  which we will issue to the  Investor at each draw down.
           The  exercise  price  of such  Warrants  will be equal to 225% of the
           daily volume  weighted  average price of the Common Stock on the date
           we furnish the Investor with a draw down notice.

      The actual  number of Shares of Common Stock which we will sell under this
Prospectus,  in certain cases, will be subject to increase or decrease depending
on the purchase price per share in effect on the actual date of sale.

      We will receive the net proceeds from the  aggregate  number of draw downs
and the call options and warrants  exercised by the  Investor.  We will use such
net proceeds for general corporate purposes.  We will bear all expenses relating
to this registration.


NASDAQ SmallCap Market Symbol: "XYBR"

      This Prospectus contains certain forward-looking  statements which involve
substantial  risks  and  uncertainties.  These  forward-looking  statements  can
generally be identified because the context of the statement includes words such
as "may," "will,"  "except,"  "anticipate,"  "intend,"  "estimate,"  "continue,"
"believe,"  or other  similar  words.  Similarly,  statements  that describe our
future plans,  objectives and goals are also  forward-looking  statements.  Such
forward-looking  statements  are subject to a number of known and unknown  risks
and uncertainties that, in addition to general economic and business conditions,
could  cause  our  actual  results,  performance,  and  achievements  to  differ
materially  from those described or implied in the  forward-looking  statements.

limited to our ability to:

      o profit from the Mobile  Assistant(R)  as  expected  (see  "Products  and
        Product Development"); 
      o meet competition (see "Competition");

      o generate cash flows  and obtain financing to  support our operations and
        growth (see "Management's Discussion and Analysis of Financial Condition
        and Results of Operations."

                               PROSPECTUS SUMMARY

         This summary  highlights some information from this Prospectus.  It may
not contain all of the information important to you. To understand this offering
fully,  you should  read the entire  Prospectus  carefully,  including  the risk
factors.

                         Information About Our Products

         Xybernaut Corporation (the "Company") is a Delaware corporation engaged
in the research,  development and  commercialization  of mobile computer systems
and  related  software  solutions  designed  to enhance  personal  productivity,
especially  in  commercial,  industrial  and military  applications.  Our latest
available  product  is  the  Mobile   Assistant(R)   133P  model,   which  is  a
full-function,  body-worn,  voice-controlled  133 MHZ Pentium(R) computer with a
head-mounted  video display ("133P").  We have also commenced  production of the
next-generation MMX Pentium(R) Mobile Assistant(R) ("MA IV").

         The  Mobile  Assistant(R)  combines  the  speed,  memory,   processing,
multimedia and communication  capabilities of a desktop personal computer ("PC")
in a lightweight unit with hands-free  operation and simultaneous user mobility.
The Mobile Assistant(R) is a combination of hardware and software designed to be
worn  on  the  body  to  perform  complex  and  time  consuming  tasks  such  as
maintenance,  repair and  inspection  of complex  technological  and  mechanical
systems,  retrieval and analysis of medical  information from remote  locations,
and  coordination  of remote  commercial and industrial  activities and military
field operations.  The Mobile  Assistant(R)  Series can utilize  technologically
advanced  features  such as real time  two-way  video  and audio  communications
through radio  frequency  transmissions,  integrated  cellular  linkups,  global
positioning system tracking  capabilities and access to information  through the
Internet and World Wide Web. The new head-mounted  display unit ("HMD") includes
a two-way audio system and optional built-in video camera,  weighs approximately
l5  ounces  and  presents  a  desk-top  quality  full VGA  color  image  that is
approximately  equivalent  to  that  of a  15"  VGA  monitor  at a  distance  of
approximately two feet. We also offer an optional  light-weight,  6.4 inch, full
VGA color, flat panel display ("FPD"), with integrated digitizer,  for users who
do not  desire  an HMD or do not need to be 100%  hands-free  and  feet-free  to
perform their job. The body-worn  computing unit is designed to allow  operation
in environmental  conditions in which conventional  portable computers could not
previously  operate,  weighs  less than two  pounds  and is  capable  of running
software applications  designed for Microsoft(R)  Windows(R) 3.11, Windows(R) 95
and 98, Windows(R) NT(TM), DOS, SCO UNIX(R) and LINUX.

         We   currently   offer  two  novel   software   products  to  get  user
documentation  up and running on the Mobile  Assistant  quickly.  The  following
products  can be used on the  Mobile  Assistant(R)  or  conventional  desktop or
laptop computers:

         o    linkAssist(TM) allows users to link information quickly regardless
              of the format of the data or where it is stored, avoiding the need
              to change,  convert or reenter the existing  information or to use
              the very technical HTML tagging process. An interesting and useful
              feature of this  product is that the linked  words or phrases  can
              then be activated by voice automatically, with no development work
              by the author of the documentation or databases.

         o    webAssist(TM)  allows voice navigation of HTML document links such
              as those  found on web sites on the World Wide Web and  intranets.
              This software  provides the user with hands-free  access to all of
              the information  found on, for example,  manufacturer and supplier
              and company-owned, web sites.

         Our  current  list of  customers  for the  Mobile  Assistant(R)  Series
include AT&T, Lucent,  NTT (Nippon Telegraph and Telephone),  Eaton Corporation,
Fujitsu,   Battelle  Memorial  Institute,   Shell  Oil,   Mitsubishi,   Rockwell
International, Lockheed Martin, and the United States Army and Navy.

                                  RISK FACTORS

         Before  you buy shares of our  Common  Stock,  you should be aware that
there are various risks associated with such purchase, including those described
below.  You should consider  carefully these risk factors,  together with all of
the other information in this Prospectus before you decide to purchase shares of
our Common Stock.

         Some of the information in this Prospectus may contain  forward-looking
statements.  Such  statements  can be identified  by the use of  forward-looking
words  such as "may,"  "will,"  "except,"  "anticipate,"  "intend,"  "estimate,"
"continue,"  "believe," or other similar words.  These statements discuss future
expectations,  contain  projections  of our  future  results  of  operations  or
financial  condition  or  state  other   "forward-looking"   information.   When
considering such statements,  you should keep in mind the risk factors and other
cautionary statements in this Prospectus. The risk factors noted in this section
and other factors  noted in this  Prospectus  could cause our actual  results to
differ materially from those contained in any forward-looking statements.

History and Expectation of Future Losses; Need for Additional Financing

         We were  incorporated  in  October  1990 and  commenced  operations  in
November 1992. We have incurred the following losses since 1994:


         Fiscal year ended:
                 o  March 31, 1994                          $47,352
                 o  March 31, 1995                       $1,303,892
                 o  December 31, 1996                    $5,238,536
                 o  December 31, 1997                    $9,479,966
         Six months ended:
                 o  June 30, 1998                        $3,792,505

         We intend to conduct significant  additional marketing and distribution
of our  products  that,  together  with our existing  research  and  development
programs,  are  expected  to  require  substantial  funding  and  to  result  in
continuing  operating  losses.  In part to subsidize such costs, we have entered
the  Financing  Arrangement  with the  Investor.  We believe that as long as the
Financing  Arrangement is in effect,  we will not need  additional  financing in
order to carry out our programs.  However, we cannot assure you that, regardless
of our  efforts  and the  expenditure  of  substantial  funds,  we will  achieve
substantial sales of any of our products, that our operations will be profitable
or that we will be able to meet the competitive demands of the industry in which
we operate.

Going Concern Qualification

         The  report of our  independent  accountants  contains  an  explanatory
paragraph regarding our ability to continue as a going concern.  The independent
accountants cited several factors as raising substantial doubt as to our ability
to continue as a going concern,  including,  our history of operating losses and
our working  capital  deficit.  We cannot  assure you that we will ever  achieve
significant revenues or that our operations will be profitable.

Liquidity; Working Capital Needs

         Under the terms of the Financing Arrangement, we must have an effective
registration  statement  covering  the  Common  Stock  which is  subject  of the
financing  prior to our first draw down.  Although we have filed a  registration
statement  on Form SB-2  covering  a certain  amount of such  shares,  we cannot
provide  any  assurance  as to if or when such  registration  statement  will be
declared effective. As a result, and in order to
    
                                      - 7 -

<PAGE>
   


meet working capital cash requirements,  we may obtain a working capital line of
credit and/or  complete  additional  financings.  In addition,  if the Financing
Arrangement  is  terminated,  we may exercise a put option to sell shares of our
Common Stock in the aggregate  principal  amount of  $7,000,000  available to us
under an April 1998 Private Equity Line of Credit Agreement.  However, we cannot
assure you that we will be able to raise additional capital, obtain funds from a
working  capital  line of  credit,  or that the sale of Common  Stock  under the
Private Equity Line of Credit  Agreement and the Financing  Arrangement  will be
deemed advisable at such times as funds may be required. We could be required to
curtail  materially,  suspend or cease  operations  if we are unable to raise or
obtain the needed working capital.

Dilution; Impact of the Conversion of Outstanding Convertible Securities

         Our sale of Common Stock to the Investor, on an continuous basis, under
the Financing Arrangement will have an immediate and substantial dilution in the
net tangible value of your Shares of the Company. The net tangible value of your
Shares will be diluted  further  upon the  conversion  of  outstanding  options,
warrants  and the  issuance of Common  Stock under a  repricing  arrangement  we
entered into in  connection  with our exercise of a $3,000,000  Put Option under
the April  1998  Private  Equity  Line of Credit  Agreement  (the  "Initial  Put
Option").  Specifically,  certain options and warrants (other than the Warrants)
are convertible  into Common Stock at discounts from future market prices of the
Common Stock.  Such discounts  could result in substantial  dilution to existing
holders of Common  Stock.  The sale of such Common Stock  acquired at a discount
could have a negative  impact on the trading price of the Common Stock and could
increase the volatility in the trading price of the Common Stock.

         At the  date of this  Prospectus,  we have  reserved  an  aggregate  of
6,827,952  shares of Common Stock for issuance  upon  exercise of the  following
outstanding options and warrants:

         o  options to purchase  1,234,550 shares at an exercise  price  between
            $1.37 and $6.00 per share;
         o  warrants to purchase  590,000 shares at an
            exercise  price  between  $1.76 and  $18.00 per  share;  
         o  warrants to purchase  3,846,429 shares at an exercise price of $9.00
            per share; and
         o  210,000 Units (the  "Units"),  each unit  consisting of one share of
            Common Stock and one Redeemable Warrant (a "Redeemable  Warrant") to
            purchase  one share of Common  Stock,  at a price of $9.075 per Unit
            during  a  period  of four  years  commencing  July  18,  1996.  The
            Redeemable  Warrants included in the Units are exercisable at $12.60
            per share.

         During the terms of the outstanding  options,  Redeemable  Warrants and
the Unit Purchase  Option,  we must give the holders the  opportunity  to profit
from a rise in the  market  price of the  Common  Stock.  The  existence  of the
options,  the  Redeemable  Warrants and the Unit  Purchase  Option may adversely
affect the terms on which we may obtain additional  equity financing.  Moreover,
the holders are likely to exercise  their  rights to acquire  Common  Stock at a
time when we would otherwise be able to obtain capital with more favorable terms
than we could obtain through the exercise of such securities.

         In addition, we agreed to certain repricing  arrangements in connection
with our exercise of the Initial Put Option.  Under that arrangement,  one-sixth
of the 545,454  shares of Common Stock (the "Initial Put Shares") we issued upon
exercise of the Initial Put Option, are subject to monthly repricing  commencing
on September 30, 1998. Under the repricing calculation,  if the closing price of
the Common Stock on the trading date immediately preceding the repricing date is
less than $7.20 per share,  the shares of Common Stock subject to repricing will
be repriced at the lowest  closing bid price of the Common Stock for the 30 days
preceding such repricing date (the "Initial Put Reset Price").  We will issue to
the investors  such number of shares (the "Initial Put Repricing  Shares") equal
to the difference  between (a) the quotient of 500,000 and the Initial Put Reset
Price and (b) the number of shares  subject to repricing.  We will not issue any
shares of Common Stock under the repricing  arrangement if the Initial Put Reset
Price is equal to or greater than $5.50.

Uncertainty of Completion of the Investment

         Our  Financing  Arrangement  with  the  Investor  provides  that if the
purchase  price of the  Common  Stock at the time of the draw  down is less than
$3.00,  the  Investor  will not be required to fund a draw down.  On October 26,
1998,  the closing bid price for a share of Common Stock as quoted on the NASDAQ
SmallCap Market was $5.0625.  However, we cannot assure you that the closing bid
price for a share of Common Stock will equal or exceed $3.00 in the future.  The
decrease of the price of our Common Stock to less than $3.00,  and the resulting
inability to draw down on the Financing  Arrangement,  may materially  adversely
affect our financial condition and results of operations.

Uncertainty of Market Development and Product Acceptance

         The mobile computing market is emerging and relatively undeveloped.  We
sold our first Mobile  Assistant(R) in 1993. From December 31, 1997 through June
30,  1998  have  sold  and  delivered  Mobile  Assistant(R)  systems  valued  at
approximately $357,000. We commenced delivery of the Pentium(R) Mobile Assistant
P-133(TM) in August 1997 and expect to commence delivery of Mobile  Assistant(R)
IV, a Pentium 233 MHZ based system ("MA IV"), in the quarter ending December 31,
1998. In September 1997, we announced the introduction of our linkAssist(TM) and
webAssist(TM) software products.

         The size of the mobile computing market is currently limited by (1) the
high unit prices of mobile  computers as compared to laptops and other  portable
computers,  (2) the  specialized  nature  of each  application  and the need for
custom applications and system  integration,  and (3) the limited supply to date
of components  for completed  systems.  The potential size of the market will be
limited further by the rate at which prospective  customers recognize and accept
the functions and capabilities of integrated mobile computing systems. We cannot
assure you that a significant  market will develop for mobile computing  systems
or, that, if a market develops,  the Mobile  Assistant(R)  Series and any of our
other products will become a significant factor in any market that develops.  In
addition,  we cannot guarantee that we will obtain the working capital needed to
meet the  competitive  demands of the  industry in which we  operate.  See "Risk
Factors - Liquidity; Working Capital Needs; -- Competition."

         In  addition,   we  believe  that  any  product   acceptance   will  be
substantially dependent upon educating the commercial, healthcare, education and
military markets as to the capabilities,  characteristics, benefits and efficacy
of the  Mobile  Assistant(R)  Series  and our  other  products,  of which we can
provide no assurance.

Competition

         The computer industry is intensely  competitive and is characterized by
rapid  technological  advances,  evolving  industry  standards and technological
obsolescence.  Many of our current  competitors have longer operating  histories
and greater financial,  technical,  sales, marketing and other resources than we
do.  Several other  companies,  including  Computing  Devices  International,  a
division of Ceridian Corporation,  ViA Inc., Texas Microsystems,  Telxon, Norand
and Teltronics,  Inc., a subsidiary of Interactive Solutions, Inc., Raytheon and
a consortium of Litton and TRW, are engaged in the  manufacture  and development
of body-mounted or hand-held computing systems that do or could compete with the
Mobile Assistant(R) Series.  Personal digital assistants and laptop and notebook
computers also are products that could compete  against the Mobile  Assistant(R)
in applications  where  hands-free,  voice-activated  operation is not required.
Many of these computers are  manufactured by major domestic and foreign computer
manufacturers  which  possess  far more  resources  than we do and  which can be
expected  to compete  vigorously  with us. We cannot  assure you that we will be
able to compete  successfully  against  our  competitors,  that we will have the
working capital needed to incorporate the constant technological advances in our
products or that  competitive  pressures will not adversely affect our financial
performance.

Dependence upon Suppliers

         We have supplier relationships with Sony Digital Products and Shimadzu,
among  others,  for the  production  of the MA IV system.  We also have  written
agreements with our suppliers for batteries, head-mounted displays and computing
units. Although we believe that we could adapt to any supply interruptions, such
occurrences could necessitate  changes in product design or assembly methods for
the Mobile  Assistant(R)  Series and cause us to experience  temporary delays or
interruptions in supply while we incorporate such changes.  Since the order time
for certain components may range up to approximately three months, we also could
experience  delays or  interruptions  in supply in the event we are  required to
find a new supplier for any of these  components.  Any  disruptions in supply of
necessary  parts and  components  from our key  suppliers  could have a material
adverse  effect on our  results of  operations.  Any future  shortage or limited
allocation  of  components  for the  Mobile  Assistant(R)  could have a material
adverse effect on our organization as a whole.

Currency Fluctuations

         The exchange  rates for some local  currencies  in  countries  where we
operate may fluctuate in relation to the U.S. dollar. Such fluctuations may have
an adverse effect on our expenses,  earnings or assets when local currencies are
translated into U.S. dollars.  We are party to a supplier  arrangement with Sony
Digital  Products for the  production of the MA IV system.  The fees we pay Sony
Digital  Products are paid in Japanese  yen.  Any  weakening of the value of the
U.S.  dollar  against  the  Japanese  yen  could  result in an  increase  in our
production expenses which, if substantial,  could have a material adverse effect
on our financial condition and results of operations.

Substantial Dependence upon Single Product Line;
Possibility of Unsuccessful New Product Development

         Our Mobile Assistant(R) Series currently consists of two products,  the
MA IV,  which is expected to be  available  for sale in late 1998,  and the 133P
model based on a 133 MHZ Intel  Pentium(R)  processor.  The Mobile  Assistant(R)
Series  are our  principal  products,  and our  success  will  depend  upon  its
commercial acceptance, which cannot be assured.

         For single unit purchases,  the Mobile  Assistant(R)  133P currently is
priced from $5,000 to $8,995 depending upon the discount and selected  features.
We also are developing  additional  products for the Mobile  Assistant(R) Series
for  introduction  in the future  and  intend to modify the Mobile  Assistant(R)
Series for use in other  applications  and to develop other  products  using our
core  technologies.  As  technological  developments  cause declines in hardware
costs,   we  expect  that  mobile  computer  sales  will  be  driven  by  system
capabilities  and  integration.  However,  we cannot  assure you that the Mobile
Assistant(R) will offer the performance  capabilities or features that customers
will value or that we will have the capital required to modify the design of the
Mobile  Assistant(R) in order to gain customer  acceptance.  In addition,  while
linkAssist(TM)  and our planned software toolkits are intended for use both with
the Mobile  Assistant(R)  Series and  independently,  we cannot guarantee that a
separate market for our existing and planned  software  products will develop or
that any products, if sold, will generate significant revenues or any profits.

         Additional product development will result in a significant increase in
our  research  and  development   expenses  that  may  be  unrecoverable  should
commercialization  of new products  prove  unsuccessful.  We also could  require
additional  funding if research  and  development  expenses  are greater than we
anticipate.  We  cannot  assure  you that we will be  successful  in our  future
product  development  efforts or in  diversifying  our product  line.  See "Risk
Factors - Liquidity; Working Capital Needs."

Uncertain Protection of Patent and Proprietary Rights;
No Assurance of Enforceability or Significant Competitive Advantage

         We consider our patent, trade secrets, and other intellectual  property
and proprietary  information to be important to our business prospects.  We rely
on a  combination  of patent,  trade secret,  copyright  and trademark  laws and
contractual  restrictions  to establish and protect our proprietary  rights.  We
have implemented a trade secret management  program to protect our trade secrets
and proprietary information.  In addition, we have confidentiality and invention
assignment   agreements   with  our   employees,   and   generally   enter  into
non-disclosure  agreements  with  our  suppliers,  VARs,  OEMs  and  actual  and
potential  customers  to  limit  access  to and  disclosure  of our  proprietary
information.

         We have registered our Mobile Assistant(R) and Xybernaut(R)  trademarks
on the  Principal  Register of the United  States  Patent and  Trademark  Office
("Patent  Office")  and the patent  and  trademark  offices  in several  foreign
countries. In April 1994, we obtained U.S. patent number 5,305,244 ("hands-free,
user- supported portable  computers") (the "Patent") for the Mobile Assistant(R)
Series.  We derived most of our revenue for the twelve months ended December 31,
1997 and 1996 and the six  months  ended  June 30,  1998 and 1997 from  products
included  within  the  scope of the  Patent.  We have  notified  several  of our
competitors of the existence of the Patent,  which our counsel believes may have
been  infringed  on by some of such  competitors.  We intend to take any and all
appropriate measures,  including legal action, necessary to maintain and enforce
our rights under the Patent and other patents held by us.

         We have filed twenty patent  applications  covering  various aspects of
computers in general and wearable  computers in particular  since July 1996. Six
of these  patent  applications  have been  issued,  one patent has been  allowed
pending  issuance and thirteen  patents are pending.  We have also filed most of
these applications in European countries, The People's Republic of China, Japan,
Republic of Korea, Republic of China (Taiwan), Canada and Australia. All patents
issued to our employees under pending and future applications have been and will
be assigned to us under existing invention assignments.

         We cannot assure you that our pending patent applications will issue as
patents,  that any issued  patent will provide us with  significant  competitive
advantages or that  challenges  will not be  instituted  against the validity or
enforceability  of any of our  patents.  The cost of  litigation  to uphold  the
validity and prevent  infringement  of patents can be  substantial.  We also can
provide no assurance that others will not independently  develop similar or more
advanced products,  design patentable  alternatives to our products or duplicate
our trade  secrets,  or that our  employees or  suppliers  will not breach their
confidentiality  agreements.  In addition, we may be required, in some cases, to
obtain licenses from  third-parties  or to redesign our products or processes to
avoid infringement.

Dependence upon and Need for Key Personnel

         Our success depends to a significant  extent upon the efforts of senior
management  personnel  and a  group  of  employees  with  longstanding  industry
relationships and technical  knowledge of our business and operations.  The loss
of certain key members of senior  management  and the  inability to replace such
member could have a material adverse effect on our business and operations.  Our
success also will depend upon our ability to attract and retain highly qualified
and experienced management and technical personnel. We face competition for such
personnel from numerous other entities, many of which have significantly greater
resources  than we do.  We  cannot  assure  you  that we will be  successful  in
recruiting  such personnel or that, if recruited,  such persons would succeed in
establishing profitable operations for our organization.

Rapid Technological Change and Risk of Obsolescence

         The  market  for   computer   products   is   characterized   by  rapid
technological  advances,  evolving  industry  standards,  changes  in  end  user
requirements  and  frequent  new product  introductions  and  enhancements.  The
introduction  of products  embodying new  technologies  and the emergence of new
industry
    
                                     - 11 -

<PAGE>

   

standards  could render our  existing  products  and  products  currently  under
development obsolete and unmarketable.  Our success will depend upon our ability
to enhance our current products and develop and successfully  introduce and sell
new  products  that keep pace with  technological  developments  and  respond to
evolving end user requirements. If we do not anticipate or respond adequately to
technological  developments,  end user  requirements,  or significant  delays in
product development or introduction, our competitive position in the marketplace
could be damaged and we could  experience a decrease in  revenues.  We expect to
increase the use of additional  external and internal resources in the near term
to meet these challenges.  However,  we can provide no assurance that we will be
successful  in hiring,  training and  retaining  qualified  product  development
personnel  to meet our needs or that we will be  successful  in  developing  and
marketing new products or product enhancements on a timely basis. Any failure to
successfully develop and market new products and product enhancements would have
a material adverse effect on our results of operations.

Year 2000 Issues

         The Year 2000 Issue is the result of computer  programs  being  written
using two digits rather than four to define the applicable  year. Any of the our
computer programs that have  date-sensitive  software may recognize a date using
"00" as the year 1900 rather than the year 2000.  This could  result in a system
failure or miscalculations causing disruptions of operations,  including,  among
other things, a temporary inability to process  transactions,  send invoices, or
engage in similar normal business activities.

         Based on a recent assessment, we determined that we will be required to
modify or replace  portions of our  software so that our  computer  systems will
properly utilize dates beyond December 31, 1999. We believe that we can mitigate
the Year 2000 Issue with  modifications to existing  software and conversions to
new software. However, if we fail to make such modifications and conversions, or
if we do not make them on a timely  basis,  the Year  2000  Issue  could  have a
material impact on our operations.

         We have contacted all of our significant  suppliers and large customers
to determine the possible effect on our operations of their inability or failure
to remediate  their own Year 2000 Issue.  Our estimate of the costs to remediate
our Year 2000 issue is based on presently  available  information.  However,  we
cannot  guarantee that the systems of other  companies on which our systems rely
will be timely converted,  or that a failure to convert by another company, or a
conversion  that is  incompatible  with our  systems,  would  not have  material
adverse effect on our operations.  We have no exposure to contingencies  related
to the Year 2000 Issue for the products we have sold.

         We will utilize both internal and external  resources to reprogram,  or
replace, and test the software for Year 2000 modifications.  We plan to complete
the Year 2000 project within six months and estimate the total remaining cost of
the Year 2000 project at $6,000.  Approximately $1,700 of the total project cost
is attributable  to the purchase of new software which will be capitalized.  The
remaining  $4,300,  which will be expensed as incurred over the next six months,
is not expected to have a material effect on our results of operations. To date,
we have  incurred and  expensed  approximately  $1,000  related to our Year 2000
project.

         Our  estimates  of the date of  completion  and  cost of our Year  2000
project are based on our best  estimates,  which we derived  utilizing  numerous
assumptions  of future events  including the continued  availability  of certain
resources,  third  party  modification  plans and other  factors.  The costs and
completion  date of our Year  2000  project  could  differ  materially  from our
estimates due to the lack of availability and cost of personnel  trained in this
area, our ability to locate and correct all relevant computer codes, and similar
uncertainties.

Effect of Possible Non-Cash Future Charge

         As  a  condition  to  our  initial  public  offering,  certain  of  our
stockholders,  primarily  officers  and  directors,  deposited  an  aggregate of
1,800,000 shares of Common Stock into an escrow account (the "Escrowed Shares").
The Escrowed Shares are subject to the following terms and conditions:
    
                                     - 12 -

<PAGE>
   

         o    The  Escrowed  Shares  will  be  released   incrementally  over  a
              three-year  period  only  in the  event  our  gross  revenues  and
              earnings  (loss)  per  share  for  the  12-month   periods  ending
              September  30, 1997,  1998 and 1999 equal or exceed  certain gross
              revenue and earnings (loss) per share targets.

         o    If such  per  share  targets  are  not met in any of the  relevant
              12-month  periods and the price of the Common  Stock does not meet
              or  exceed  agreed  upon  price  levels,  certain  amounts  of the
              Escrowed  Shares  will  be  returned  to us for  each  period  and
              canceled.

         o    All the Escrowed  Shares will be released to the  stockholders  if
              the  closing  price of the Common  Stock as reported on The Nasdaq
              SmallCap  Market  following this offering equals or exceeds $11.00
              for 25  consecutive  trading  days  or 30  out  of 35  consecutive
              trading days during the period ending September 30, 1999.

         The difference  between the initial offering price and the market value
(at the time of release) of any Escrowed Shares released will be deemed to be an
additional compensation expense. Such expense, depending on the price per share,
may have the effect of reducing or eliminating  any earnings per share and could
have a negative effect on the market price for our Common Stock.

         We did not meet the targets for escrow  release for  September 30, 1997
and September 30, 1998. As a result,  300,000 and 750,000 shares,  respectively,
were canceled from the escrow pool  resulting in a reduction of 2.1% and 3.6% of
our outstanding shares of Common Stock.

High Concentration of Common Stock Held by Existing Stockholders

         Following  this  offering,   our  executive  officers,   directors  and
principal  stockholders  will, in the aggregate,  beneficially own approximately
29.3% of our outstanding shares of Common Stock. These  stockholders,  if acting
together, will be able to effectively control most matters requiring approval by
our  stockholders.   The  voting  power  of  these  stockholders  under  certain
circumstances  could  have the  effect of  delaying  or  preventing  a change in
control of the Company.

Limitation of Liability

         Our  Certificate of  Incorporation  provides  that,  subject to limited
exceptions,  our directors will not be personally liable for monetary damages to
us or our  stockholders  for a breach of fiduciary duty as a director.  Although
such  limitation  of  liability  does not affect the  availability  of equitable
remedies  such as  injunctive  relief or  rescission,  these  provisions  of the
Certificate  of  Incorporation  could  prevent the recovery of monetary  damages
against our directors. See "Indemnification for Securities Act Liabilities."

Shares Eligible for Future Sale

         Sales of a  substantial  number of shares  of our  Common  Stock in the
public market following this offering could adversely affect the market price of
the  Common  Stock.  Of the  23,621,583  shares  of  Common  Stock  that will be
outstanding  or  registered  for sale  upon  the  completion  of this  offering,
22,391,426 will be freely tradeable without restriction or further  registration
under the Securities Act. This includes:

         o   19,250,246 shares of Common Stock which are issued and outstanding;
         o   141,700  unissued  shares of Common Stock  registered in connection
             with the Series C Preferred Stock,
         o   899,480  unissued shares of Common  Stock  registered in connection
             with  the April  1998 Equity Line of Credit  Private Placement; and
         o   the  2,100,000  unissued  shares of  Common  Stock  registered  in
             connection with the Financing Arrangement.

<PAGE>
   

         The remaining  1,014,140  shares include 750,000 shares of Common Stock
which are "Escrowed  Shares" (see "Executive  Compensation -- Escrowed  Shares")
and are subject to incremental  release over a one-year  period if certain share
targets  are met,  and  480,157  shares  of the  Common  Stock  are  "restricted
securities" as that term is defined in Rule 144 promulgated under the Securities
Act. The  restricted  shares may be sold  pursuant to an effective  registration
statement under the Securities Act, in compliance with the exemption  provisions
of Rule 144 or pursuant to another  exemption  under the Securities  Act. In the
absence of any  agreement to the contrary,  the  outstanding  restricted  Common
Stock could be sold in accordance  with one or more other  exemptions  under the
Securities  Act  (including  Rule 144).  Rule 144, as amended,  permits sales of
restricted  securities  by any person  (whether or not an  affiliate)  after one
year, at which time sales can be made subject to the Rule's  existing volume and
other limitations and by non-affiliates  without adhering to Rule 144's existing
volume or other limitations after two years. Future sales of substantial amounts
of shares in the public market,  or the perception  that such sales could occur,
could  adversely  affect the price of the shares in any market  that may develop
for the trading of such shares.

No Dividends Anticipated

         We  have  never  paid  any  dividends  on  our  securities  and  do not
anticipate the payment of dividends in the foreseeable future.

Volatility of Stock Price

         The trading price of the Common Stock has been, and may continue to be,
volatile.  Such trading price could be subject to wide  fluctuations in response
to our  announcements  of business and  technical  developments  or those by our
competitors,  quarterly  variations  in operating  results,  and other events or
factors,  including our prospects and  expectations  by investors and securities
analysts.  In addition,  stock markets have experienced extreme price volatility
in recent years.  This  volatility  has had a  substantial  effect on the market
prices of development  stage companies,  at times for reasons unrelated to their
operating  performance.  Such broad market fluctuations may adversely affect the
price of our Common Stock.

Anti-takeover Consideration; Rights of Preferred Stock

         Our  Certificate  of  Incorporation  authorizes  the  issuance of up to
6,000,000 shares of $.01 par value preferred stock (the "Preferred  Stock").  As
of the date of this Prospectus, only the Series C Preferred Stock are issued and
outstanding.  The  authorized  and unissued  Preferred  Stock may be issued with
voting,  conversion or other terms  determined  by the Board of Directors  which
could be used to delay,  discourage  or prevent a change of control.  Such terms
could include,  among other things,  dividend payment  requirements,  redemption
provisions,  preferences  as to dividends  and  distributions  and  preferential
voting rights.  The issuance of Preferred  Stock with such rights could have the
effect of limiting  stockholder  participation in certain  transactions  such as
mergers  or  tender  offers  and  could  discourage  or  prevent a change in our
management.  We have no  present  intention  to issue any  additional  Preferred
Stock. See "Description of Securities -- Preferred Stock."

         We have a classified  or staggered  Board of Directors  which limits an
outsider's  ability  to  effect a rapid  change  of  control  of the  Board.  In
addition, at the 1998 Annual Meeting of Stockholders held on September 24, 1998,
our shareholders approved measures to amend our Certificate of Incorporation and
Bylaws, where applicable, to:

         o    implement  an  advance  notice  procedure  for the  submission  of
              director nominations and other business to be considered at annual
              meetings of stockholders;

         o    permit only the  President,  the Vice  Chairmen of the Board,  the
              Secretary or the Board of  Directors  to call special  meetings of
              stockholders and to limit the business permitted to be

<PAGE>
   


              conducted at such meetings to be brought before the meetings by or
              at the direction of the Board of Directors;

         o    provide  that a  member  of the  Board  of  Directors  may only be
              removed for cause by an affirmative vote of holders of at least 66
              2/3% of the voting power of the then  outstanding  shares entitled
              to vote generally in the election of directors  voting together as
              a single class (the "Voting Stock");

         o    fix the size of the  Board of  Directors  at a  maximum  of twelve
              directors, with the authorized number of directors set at ten, and
              the Board of  Directors  having  the sole power and  authority  to
              increase  or  decrease  the  number  of  directors  acting  by  an
              affirmative  vote of at least a  majority  of the total  number of
              authorized   directors   most  recently  fixed  by  the  Board  of
              Directors;

         o    provide that any vacancy on the Board of  Directors  may be filled
              for  the  unexpired  term  (or for a new  term  in the  case of an
              increase in the size of the board) only by an affirmative  vote of
              at least a majority of the remaining directors then in office even
              if less than a quorum, or by the sole remaining director;

         o    eliminate stockholder action by written consent;

         o    require  the  approval  of holders of 80% of the then  outstanding
              Voting Stock and/or the approval of 66 2/3% of the  directors  for
              certain corporate transactions; and

         o    require  an  affirmative  vote of 66 2/3% of the  Voting  Stock in
              order to amend or repeal any adopted amendments to the Certificate
              of Incorporation and Bylaws adopted at the meeting.

         Such  measures,  combined with the ability of the Board of Directors to
issue "blank check" Preferred Stock and the staggered Board of Directors,  could
have the effect of delaying, deterring or preventing a change in control without
any further  action by the  shareholders.  In  addition,  issuance of  Preferred
Stock, without shareholder approval, on such terms as the Board of Directors may
determine,  could adversely affect the voting power of the holders of the Common
Stock,  including  the loss of voting  control to others.  See  "Description  of
Securities."

                              FINANCING ARRANGEMENT

         Pursuant  to  the  Financing  Arrangement,  immediately  following  the
effective  date of the  Registration  Statement of which this  Prospectus  is an
integral  part,  we, at our  option,  may present  the  Investor  with a weekly,
monthly or  quarterly  draw down  request for the  purchase  of up to  $600,000,
$2,400,000 and $7,200,000, respectively, of the our Common Stock (each request a
"Draw Down Request"). We may present a Draw Down Request during the twelve month
period commencing on the date of the initial draw down.

         The  purchase  price of such shares shall be equal to the lesser of (1)
the average of the daily volume  weighted  average  price of the Common Stock on
NASDAQ  SmallCap  Market  for a  certain  number  of  consecutive  trading  days
preceding the funding date of the draw down and (2) $8.00. However, the Investor
is not obligated to accept any draw down if the purchase  price of the shares is
less than $3.00.

         We will set the lowest  price at which we will  issue our shares  under
the Financing  Arrangement (the "Threshold Price").  The Threshold Price may not
be set below $3.00.  If the average  daily price on a given  trading day is less
than the Threshold Price then the Investor's  payment  obligation under the draw
down will be reduced by 1/5th,  1/20th or an agreed upon  fraction for a weekly,
monthly or quarterly draw down, respectively.

         Upon acceptance of our Draw Down Request, the Investor,  at its option,
may purchase an  additional  amount of Common Stock up to the maximum  amount of
each draw  down.  The  price of such  shares  will be equal to the daily  volume
weighted  average  price of our Common  Stock on the NASDAQ  Small Cap Market as
reported by  Bloomberg  Financial  using the AQR function on the date we present
our Draw Down Request. The Investor's right to purchase additional shares of our
Common Stock may be exercised only with respect to each Draw Down Request and is
waived for the period it remains unexercised.

         The  Investor  will  receive a Warrant to purchase  12,500,  50,000 and
150,000 shares of Common Stock for each weekly, monthly and quarterly draw down,
respectively. Each Warrant will have a three-year exercise period commencing six
months  from the  funding  date of the draw  down.  The  exercise  price of each
Warrant will be 225% of the average  daily price of the Common Stock on the date
we present our Draw Down Request.
    
         The shares  issuable upon acceptance of all Draw Down Requests and upon
exercise of the Warrants are the subject of this Prospectus.

         The term of the  Financing  Arrangement  is for twelve  months from the
initial  Draw Down,  unless  earlier  terminated  by either party or extended by
mutual consent of the parties.

<PAGE>
   

                                 USE OF PROCEEDS

         We will receive proceeds from the draw downs, the Call Options, if any,
and the exercise of the Warrants issued  pursuant to the Financing  Arrangement.
We  expect  to use the net  proceeds  (after  deduction  of  estimated  offering
expenses) from the Financing Arrangement for general corporate purposes.

                                 DIVIDEND POLICY

         We have never declared or paid cash  dividends on our Common Stock.  We
currently  anticipate  that we will  retain all  available  funds for use in the
operation  of our  business.  As  such,  we do not  anticipate  paying  any cash
dividends on our Common Stock in the foreseeable future.

                    MARKET FOR REGISTRANT'S COMMON EQUITY AND
                           RELATED STOCKHOLDER MATTERS

         On July 18, 1996, we successfully completed our initial public offering
and sold  2,415,000  Units at a price of $5.50 per Unit.  Each Unit consisted of
one share of Common  Stock and one  Redeemable  Warrant  to  purchase a share of
Common Stock at $9.00. Units were traded on the NASDAQ SmallCap Market from July
18, 1996 until August 20, 1996,  at which time the Units were  delisted from the
exchange. The Common Stock and the Redeemable Warrants have traded separately on
the NASDAQ  SmallCap  Market  since July 29, 1997 under the  symbols  "XYBR" and
"XYBRW".

         As of September  30, 1998,  we had  approximately  1,200 holders of our
Common Stock.  We have not paid any cash  dividends on our Common Stock to date.
We do not anticipate the payment of dividends in the foreseeable future.

         The table below sets forth by quarter,  for the periods indicated,  the
high  and low  market  prices  of our  Common  Stock  and  Redeemable  Warrants.
Quotations reflect prices between dealers,  without retail mark-up, mark down or

                             SELECTED FINANCIAL DATA

         The following  selected financial data as of December 31, 1997, and for
each of the two years  then  ended,  have  been  derived  from our  consolidated
financial   statements.   Our   financial   statements   have  been  audited  by
PricewaterhouseCoopers  LLP,  independent  accountants,  as set  forth  in their
report dated March 31, 1998, which includes an explanatory paragraph, concerning
our ability to continue as a going concern.

         The selected  financial data as of June 30, 1998 and for the six months
ended June 30, 1998 and 1997, have been derived from our unaudited  consolidated
financial statements,  which, in our opinion contain all adjustments (consisting
only of normal and recurring  adjustments)  necessary for a fair presentation of
such data. The result of the interim periods are not  necessarily  indicative of
the results of a full year.  You should read all of the financial data set forth
below in conjunction  with our consolidated  financial  statements and the notes
thereto included  elsewhere in this  Prospectus.  You should also read carefully
the  information  appearing  under  the  caption  "Management's  Discussion  and
Analysis of Financial Condition and Results of Operations."

</TABLE>

Six Months Ended June 30, 1998 Compared to Six Months Ended June 30, 1997

   
         Revenues.  Total  revenues  for the six months ended June 30, 1998 were
$358,700,  an  increase  of  $108,242,  or 43%,  compared  to  $250,458  for the
corresponding period in 1997. Product revenues for the six months ended June 30,
1998 were $356,861,  an increase of $136,403,  or 62%,  compared to $220,458 for
the corresponding period in 1997. The increase in product revenues for the three
months ended June 30, 1998 was related to the higher number of 133P Systems that
we sold during that period,  compared to the lower number of 486 and 586 Systems
that we sold in the corresponding period in 1997. The decrease in consulting and
license  revenues  was due to the  lack of  sales  activity  under  our  license
agreement with Rockwell  International  that was related to the restructuring of
Rockwell's operations.

         Cost of sales. The cost of goods sold for the six months ended June 30,
1998 was $379,476,  a decrease of $30,314,  or 7%,  compared to $409,790 for the
corresponding  period in 1997. The cost of goods sold  increased  commensurately
with  the  increase  in  sales  but  were  offset  by (1)  charges  in  1997  of
approximately  $97,000 of parts for 586 Systems  that were  replaced and written
off, and (2) a full reserve for obsolescence of  approximately  $225,000 for the
remaining  computing  units used in 486 Systems,  which we believe are saleable,
but whose value is uncertain  given  changes in  technology  and advances in the
market.

         Sales and marketing expenses.  Sales and marketing expenses for the six
months  ended June 30, 1998 were  $1,151,147,  a decrease of  $338,048,  or 23%,
compared to $1,489,195 for the  corresponding  period in 1997. This decrease was
due to (1) a change in compensation structure for sales personnel which
    

                                     - 19 -

<PAGE>



   
resulted in lower base salaries,  (2) a reduction in travel related expenses due
to the  centralization  of sales staff, and (3) a decrease in the use of outside
consultants for sales and marketing programs.
    

         General  and  administrative   expenses.   General  and  administrative
expenses for the six months ended June 30, 1998 were  $1,617,879,  a decrease of
$267,335,  or 14%, compared to $1,885,214 for the corresponding  period in 1997.
This  decrease  resulted  primarily  from a reduction in  personnel  and related
occupancy  expenses,  along  with a  decrease  in travel  expenses.  These  were
partially  offset  by  an  increase  in  activities   related  to  international
operations.

   
         Research and development  expenses.  Research and development  expenses
for the six months ended June 30, 1998 were $1,010,769,  a decrease of $185,550,
or 16%,  compared  to  $1,196,319  for the  corresponding  period in 1997.  This
decrease resulted  primarily from reduced activity and related expense given the
substantial  completion  of  development  for the  head-mounted  display and the
body-worn  computing unit for the 133P, and the sharing of development  expenses
for the  Mobile  Assistant  IV System  with our  development  and  manufacturing
partners.

         Interest income, net. Net interest income for the six months ended June
30, 1998 was $8,066, a decrease of $41,063,  or 84%, compared to $49,129 for the
corresponding  period in 1997.  This decrease is the result of reduced  interest
income from the lower  average  cash  balances in the six months  ended June 30,
1998 than for the  corresponding  period in 1997,  which  reflected the interest
income on proceeds from our July 1996 initial public offering.

         Dividend on preferred  stock. We issued our Series C Preferred Stock on
May 15, 1998. The Series C Preferred Stock accrues  dividends at 5% per annum on
the outstanding  principal  amount.  For the six months ended June 30, 1998, the
amount  of  accrued  dividend  was  $2,344,  with  no  comparable  item  for the
corresponding period in 1997.

         Net loss  attributable  to common  stock.  As a result  of the  factors
described  above,  the net  loss for the six  months  ended  June  30,  1998 was
$3,794,849,  a decrease of  $886,082,  or 19%,  compared to  $4,680,931  for the
corresponding  period in 1997.  Although we were subject to taxation  during the
six months  ended  June 30,  1998 and the six months  ended  June 30,  1997,  we
incurred net losses during these periods and no provision for taxes was made.
    

Year Ended December 31, 1997 Compared to Year Ended December 31, 1996

   
         Revenues.  Revenues for the year ended December 31, 1997 were $812,522,
a decrease  of  $280,819,  or 26%,  compared  to  $1,093,341  for the year ended
December 31, 1996.  Product  revenues for the year ended  December 31, 1997 were
$555,522,  a  decrease  of  $373,210  or  40%,  compared  to  $928,732  for  the
corresponding period in 1996. The reduction in product revenues for the year was
related to the lower number of 133P Systems and Mobile  Assistant(R)  II Systems
that were sold during that period,  compared to the higher number of 486 Systems
that  were sold in the  corresponding  period in 1996.  Consulting  and  license
revenues  for the year ended  December  31, 1997 were  $257,000,  an increase of
$92,391,  or 56%,  compared to $164,609  for the  corresponding  period in 1996.
During the year ended  December 31, 1997,  our licensee  elected to not continue
with its business  activities under our license as a result of the restructuring
of its business operations.  A portion of the consideration we received in March
1996 for granting this license was a $300,000 cash payment, which we recorded as
deferred  license  revenue.  We  amortized  this amount over a five year period.
Given the  licensee's  stated  intent  to not to  continue  conducting  business
operations  under the license,  we recorded  the  remaining  deferred  licensing
revenue of  $220,000 as of June 30,  1997 as revenue in the three  months  ended
September 30, 1997.
    


                                     - 20 -

         Cost of sales.  The cost of sales for the year ended  December 31, 1997
was $1,225,572,  an increase of $144,375, or 13%, compared to $1,081,197 for the
year ended December 31, 1996.  The cost of goods sold  decreased  commensurately
with the  decrease in product  sales but was offset by charges of  approximately
$725,000 to reduce the carrying  value of the computing  unit for the 486 System
and the Mobile  Assistant(R) II to estimated market value and to reduce carrying
values of several  components of our  head-mounted  displays to estimated market
value.

         Research and development  expenses.  Research and development  expenses
for the year ended December 31, 1997 were  $2,350,237,  an increase of $577,222,
or 33%,  compared to  $1,773,015  for the year ended  December  31,  1996.  This
increase  reflects our ongoing research and development  efforts,  including the
addition of new personnel, the operation of the design center in California, the
internal development of a head-mounted display, the development of the body-worn
computing  unit for the  Mobile  Assistant(R)  II,  the 133P and the MA IV,  and
software development.

         Sales and marketing expenses. Sales and marketing expenses for the year
ended December 31, 1997 were  $3,280,356,  an increase of  $1,838,210,  or 128%,
compared to  $1,442,146  for the year ended  December  31, 1996.  This  increase
resulted  mainly from  increases in personnel,  related  travel,  infrastructure
costs to support sales,  VAR training  programs,  customer  service,  additional
marketing  programs  to  support  the  launch of new  products,  and  public and
investor  relations  efforts,   expenses  related  to  the  establishment  of  a
representative  office in Tokyo, Japan and negotiations with potential licensees
in the Far East and Europe, along with charges of approximately $253,000 related
to a receivables whose collectability was deemed to be doubtful and were written
off and an expense of approximately $125,000 related to the issuance of warrants
to a consultant.

         General  and  administrative   expenses.   General  and  administrative
expenses for the year ended  December 31, 1997 were  $3,518,868,  an increase of
$1,360,656, or 63%, compared to $2,158,212 for the year ended December 31, 1996.
This increase resulted primarily from an increase in personnel,  consulting, and
travel  expenses  related to the  expansion  and  continued  development  of our
infrastructure,   and  activities  related  to  discussions   regarding  certain
strategic partnerships and international operations.

         Interest  income,  net. Net interest income for the year ended December
31, 1997 was $82,545,  an decrease of $40,148,  or 33%, compared to net interest
income of  $122,693  for the year ended  December  31,  1996.  This  decrease is
primarily  the result of lower  average  monthly  cash  balances  in fiscal 1997
versus those during fiscal 1996,  when we received cash from our initial  public
offering.

         Dividend on preferred  stock,  deemed  dividend  accretion on preferred
stock.  We issued our Series A Preferred  Stock on June 30,  1997.  The Series A
Preferred Stock accrues  dividends at 5% per annum on the outstanding  principal
amount.  We issued our Series B Preferred Stock on November 11, 1997. The Series
B Preferred Stock accrues dividends at 4% per annum on the outstanding principal
amount. For the year ended December 31,1997,  the amount of accrued dividend was
$82,905,  with no  comparable  item for the  corresponding  period  in 1996.  In
accordance  with the Emerging  Issues Task Force report from the  Securities and
Exchange Commission titled "Accounting for the Issuance of Convertible Preferred
Stock and Debt  Securities with a  Nondetachable  Conversion  Feature," a deemed
dividend was assumed for the Series A and Series B Preferred  Stock,  which will
be  accreted  periodically  as  portions  of the Series A and Series B Preferred
Stock are  convertible  into Common Stock.  The amount of this accretion for the
year ended  December  31, 1997 was  $488,693,  with no  comparable  item for the
corresponding  period in 1996.  Additional  paid in  capital  is  reduced by the
amount of accretion and preferred stock is increased by the amount of accretion,
resulting in no impact on the overall amount of stockholder's equity.

         Net loss  attributable  to holders of common stock.  As a result of the
factors  described above,  the net loss  attributable to holders of Common Stock
for the year ended December 31, 1997 was $10,051,564, an
    
                                     - 21 -

increase  of  $4,813,028,  or 92%  compared  to  $5,238,536  for the year  ended
December  31, 1996.  Although we were subject to taxation  during the year ended
December 31, 1997 and the year ended  December 31, 1996,  we incurred net losses
during these periods and no provision for taxes was made.

Liquidity and Capital Resources

         Since  our  inception  until  the  completion  of  our  initial  public
offering,  we  have  financed  our  operations  from  the  private  sale  of our
securities,   from  vendor  credit  and  from  short-term  loans  received  from
management, stockholders and others.

         From October 1994 to August 1995,  we raised  approximately  $1,243,000
from the private sale of shares of Common Stock at $6.00 per share.  In November
1995,  we  raised  $1,505,000  through  the  private  placement  of  convertible
debentures  and in April 1996,  we raised  $1,000,000  through a second  private
placement of convertible debentures.  We received approximately  $2,140,000 from
these financings net of offering costs. We carried the placement fees in respect
of these financings as interest-bearing  loans which we repaid from the proceeds
of our initial public  offering.  We realized  gross  proceeds of  approximately
$13,280,000  and  net  proceeds  of  approximately   $10,840,000  after  related
expenses.

         On June 30, 1997, we completed a $3 million private  placement of 3,180
shares of  Series A  Preferred  Stock,  par value  $0.01  per share  ("Series  A
Preferred  Stock"),  from which we realized gross proceeds of $3,000,000 and net
proceeds of approximately  $2,762,000 after related expenses. The holders of the
Series A Preferred Stock converted all of such shares  resulting in the issuance
of 1,958,984 shares of Common Stock.

         On November 12, 1997,  we completed a $3 million  private  placement of
3,000 shares of Series B Preferred  Stock,  par value $0.01 per share ("Series B
Preferred  Stock"),  from which we realized gross proceeds of $3,180,000 and net
proceeds of  approximately  $2,950,000 after related  expenses.  On February 23,
1998,  we  completed  a  follow-on  placement  of Series B  Preferred  Stock and
realized gross proceeds of $1,000,000 and net proceeds of approximately $990,000
after related  expenses.  The holders of the Series B Preferred  Stock converted
all of such  shares  resulting  in the  issuance of  3,172,239  shares of Common
Stock.

         In April 1998, we entered into an equity line of credit  agreement from
which we received an initial  gross amount of  $1,000,000 in exchange for Common
Stock. Under this line of equity, we have the right, but not the obligation,  to
obtain up to an additional $10,000,000 in a series of equity draw downs based on
terms and conditions  specified in the line of credit.  In connection  with this
line of equity, we issued five-year  warrants to purchase up to 40,000 shares of
stock at $1.76  and  20,000  shares of stock at $2.81 at any time  starting  six
months after closing.  The placement agent for this transaction  received a cash
fee of 5% and 50,000 shares of unregistered stock.

         In May 1998, we completed a $750,000 private placement of 375 shares of
Series C Preferred Stock, par value $0.01 per share ("Series C Preferred Stock")
and 110,294  shares of Common Stock.  The Series C Preferred  Stock has a stated
value of $1,000 per share. A holder of the Series C Preferred  Stock is entitled
to receive, if and when declared, a dividend equal to 5% of the stated value per
share per annum,  payable  in shares of Common  Stock or in cash,  payable  upon
conversion of the Series C Preferred  Stock.  The  Certificate of Designation of
the Series C Preferred  Stock  provides us with several  redemption  options and
allows for the periodic  conversion of portions of unredeemed Series C Preferred
Stock over a two-year  period ending May 15, 2000. Any Series C Preferred  Stock
outstanding on May 15, 2000 must be converted into Common Stock at that date.

         In June 1998, we completed a $1,000,000  private  placement in which we
issued  153,846  unregistered  shares  of  Common  Stock at a price of $6.50 per
share.

         In June 1998,  we amended and  exercised a put option in the  aggregate
principal  amount of  $3,000,000  under the April 1998  private  equity  line of
credit  agreement  mentioned  above. In connection  with such action,  we issued
545,454  shares of Common  Stock.  Such  shares are subject to  restrictions  on
resale for a period of nine months and to repricing upon  occurrences of certain
conditions.  In addition, we issued five-year warrants to purchase up to 300,000
shares of Common Stock at a price of $5.25.

         We used cash of  $3,366,073  in our  operating  activities  for the six
months ended June 30, 1998. This amount was primarily the result of a $3,792,505
net loss.  The net loss was offset by a net decrease in inventories of $109,731,
depreciation and amortization of $152,185 and non-cash charges for tooling costs
of  $138,682.  We used cash of $198,765  for  investing  activities  for the six
months ended June 30, 1998 which included $91,190 related to patents and $74,060
in  capitalized  tooling  costs.  We received  proceeds of  $6,627,195  from our
financing  activities  for the six months  ended June 30,  1998 which  primarily
consisted of $5,307,048  from our issuance of Common Stock,  net of related fees
and $1,348,496 from our issuance of Series B and Series C Preferred  Stock,  net
of related fees. As a result,  cash and cash  equivalents on hand as of June 30,
1998 were  $4,014,723,  an increase of $3,062,357  from the $952,366 of cash and
cash equivalents on hand as of December 31, 1997.

         We used cash of  $4,986,509  in our  operating  activities  for the six
months ended June 30, 1997. This amount was primarily the result of a $4,680,931
net loss,  an  increase  in  inventories  of  $295,792  largely  related  to the
production  of the 586 System  and our head  mounted  display,  an  increase  in
prepaid  and other  current  assets of  $184,312,  offset  by  depreciation  and
amortization costs of $160,547 and non-cash  compensation costs of $125,488.  We
used cash of $747,144 for investing activities for the six months ended June 30,
1997 which  included  $306,962 for the  acquisition  of property and  equipment,
$284,294 in  capitalized  tooling  costs  related to the  production  of the 586
System  and our head  mounted  display,  and  $155,188  related to  patents.  We
received proceeds of $2,951,076 from our financing activities for the six months
ending June 30, 1997 which  primarily  consisted of $2,785,000 from our issuance
of Series A  Preferred  Stock and  deferred  placement  fees of  $215,000.  As a
result,  cash and cash equivalents on hand as of June 30, 1997, were $3,492,390,
a decrease of $2,782,577  from the  $6,274,967 of cash and cash  equivalents  on
hand as of December 31, 1996.

         We used cash of  $10,062,427  in our operating  activities for the year
ended  December  31, 1997  compared to cash of  $5,133,942  we used for the year
ended  December 31, 1996. The net use of cash during the year ended December 31,
1997 was  primarily  the  result  of a  $9,479,966  net  loss  and cash  used by
inventory  of  $1,930,378,  offset by a net  increase  in  accounts  payable and
accrued expenses of $515,466 and  depreciation and amortization of $277,299.  We
used cash of $866,228 for investing  activities  for the year ended December 31,
1997,  which  included  $364,678 for the  acquisition of property and equipment,
$231,298   related  to  obtaining  and  maintaining   patents  and  $270,252  in
capitalized tooling costs. We received proceeds of $5,606,054 from our financing
activities for the year ended December 31, 1997. This amount primarily consisted
of  $5,710,406  from the  issuance of our Series A Preferred  Stock and Series B
Preferred  Stock,  and  $56,500 of  proceeds  from  notes and  loans,  offset by
payments on notes and loans  totaling  $72,232,  and  $16,667 for the  remaining
payment on the acquisition of Tech Virginia and repayment of loans. As a result,
cash and cash  equivalents  on hand as of  December  31, 1997 were  $952,366,  a
decrease of  $5,322,601  from the  $6,274,967 of cash on hand as of December 31,
1996.

         We used cash of  $5,133,942 in our  operating  activities  for the year
ended  December 31, 1996.  This amount was  primarily the result of a $5,238,536
net loss combined with  $354,871 of cash used by  inventories,  $337,065 used by
accounts  receivable  and  $177,094 for prepaid and other  assets,  offset by an
increase in accounts payable and accrued expenses of $177,619 and an increase in
deferred  licensing  revenue of $250,000.  We used cash of $315,257 in investing
activities in the year ended  December 31, 1996 for the  acquisition of property
and equipment,  $114,618 related to the acquisition of patents,  and $106,738 of
capitalized  tooling and other assets.  We received proceeds of $11,436,856 from
our financing activities in

the year ended December 31, 1996 which consisted primarily of $13,282,500 raised
at our initial public  offering and $1,000,000 from the placement of Convertible
Debentures  prior to our initial public  offering,  offset by fees of $2,561,149
and net loan repayments of $251,161.

         At June 30, 1998, we had no material  capital  commitments  and working
capital of $4,492,263.

         In September 1998, we entered into the Financing  Arrangement  with the
Investor  pursuant to which,  we may, at our option,  sell up to  $31,200,000 of
Common Stock to the  Investor  during a twelve  month  period.  The Investor may
exercise its Call Option for an  additional  $31,200,000.  To fully  utilize the
Financing  Arrangement,  we may need to  register  additional  shares  of Common
Stock. See "Financing Arrangement."

         We have entered into a financing  agreement  with the same  investor on
terms comparable to those of the Financing Arrangement. Under this agreement, we
may sell  between  $2,700,000  and  $5,400,000  of Common  Stock to the investor
during the period from October 8, 1998 to November 15, 1998. At the date of this
Prospectus,  we have issued  216,017 shares of  unregistered  Common Stock under
this financing agreement from which we have received $900,000 in gross proceeds.

         We  anticipate  that our working  capital  requirements  and  operating
expenses  will  increase  as we  expand  production  and  sales  of  the  Mobile
Assistant(R),  and expand our full sales, service and marketing  functions,  and
develop the support structure for these  activities.  The timing of increases in
personnel  and  other  expenses,  the  amount of  working  capital  consumed  by
operations,  marketing  and  rollout  expenses  for the MA IV,  and  competitive
pressures on gross  margins will impact the magnitude and timing of the our cash
requirements.  To meet working  capital  needs,  we entered  into the  Financing
Arrangement  with the  Investor.  In the  event  the  Financing  Arrangement  is
terminated, we may also exercise an existing put option to sell up to $7,000,000
of Common Stock under the April 1998 Private Equity Line of Credit Agreement. In
addition,  we intend  to use funds  from  operations,  and may  obtain a working
capital line of credit and/or complete additional financings,  if necessary.  We
believe that additional funding arrangements are readily available to us and the
execution of any such arrangement will depend on timing,  market  conditions and
the  final  terms  and  conditions  of such  arrangements.  We will  begin  full
production  of the MA IV  model of the  Mobile  Assistant(R)  will  begin in the
quarter ending December 31, 1998 and expect  receivables from sales of the MA IV
to provide  collateral for borrowing  facilities at that point.  Although we can
provide no assurance that such facilities  will be available,  we intend to seek
to establish secured borrowing facilities at such time as appropriate collateral
is available.  We believe that the  combination of cash on hand,  operating cash
flow,  and outside  funding will provide  sufficient  liquidity to meet our cash
requirements  until at least March 1999.  However,  we can provide no  assurance
that we can or will obtain  sufficient  funds from  operations or from a working
capital line of credit or from closing additional financings on terms acceptable
to us.

Possible Impact on Near-Term Revenues

         We have agreements with third-party suppliers to manufacture and supply
the body-worn  computing unit, the HMD and the batteries for the 133P and the MA
IV. We have  substantially  curtailed  production of the computing  unit for the
133P pending the  introduction of the MA IV in the fourth  quarter,  although we
believe that we can restart  production  to meet large orders.  As a result,  we
expect  revenue growth to be modest through the first three quarters of the year
ending  December  31,  1998,  until  the  MA IV  suppliers  commence  full-scale
production  and those units are sold in volume,  which we expect to begin in the
quarter ending December 31, 1998. Delays, for any reason, in the commencement of
full-scale  production of the MA IV units may adversely  affect revenues for the
year ending December 31, 1998.

         Exchange rates for some local  currencies in countries where we operate
may  fluctuate in relation to the U.S.  dollar.  Such  fluctuations  may have an
adverse effect on our earnings when local  currencies  are translated  into U.S.
dollars.

Possible Non-Cash Future Charge

         As a  condition  to  our  initial  public  offering  ,  certain  of our
stockholders,  primarily  officers  and  directors,  deposited  an  aggregate of
1,800,000 shares of Common Stock into an escrow account.  The difference between
the initial  offering price and the market value (at the time of release) of any
Escrowed  Shares  released  will  be  deemed  to be an  additional  compensation
expense. Such expense,  depending on the price per share, may have the effect of
reducing or eliminating  any earnings per share and could have a negative effect
on the market price for our Common Stock. See "Risk Factors - Effect of Possible
Non-Cash Future Charge."

General

Information About Our Products

         We are engaged in the research,  development and  commercialization  of
mobile  computer  systems and  related  software  solutions  designed to enhance
personal  productivity,   especially  in  commercial,  industrial  and  military
applications.  Our latest  available  product is the  Mobile  Assistant(R)  133P
model, which is a full- function, body-worn, voice-controlled 133 MHZ Pentium(R)
computer with a head-mounted video display. We have also commenced production of
the next-generation MMX Pentium(R) Mobile Assistant(R).

         The  Mobile  Assistant(R)  combines  the  speed,  memory,   processing,
multimedia and  communication  capabilities of a desktop personal  computer in a
lightweight unit with hands-free  operation and simultaneous user mobility.  The
Mobile  Assistant(R)  is a combination  of hardware and software  designed to be
worn  on  the  body  to  perform  complex  and  time  consuming  tasks  such  as
maintenance,  repair and  inspection  of complex  technological  and  mechanical
systems,  retrieval and analysis of medical  information from remote  locations,
and  coordination  of remote  commercial and industrial  activities and military
field operations.  The Mobile  Assistant(R)  Series can utilize  technologically
advanced  features  such as real time  two-way  video  and audio  communications
through radio  frequency  transmissions,  integrated  cellular  linkups,  global
positioning system tracking  capabilities and access to information  through the
Internet  and World Wide Web.  The new head-  mounted  display  unit  includes a
two-way audio system and optional built-in video camera, weighs approximately l5
ounces  and   presents  a  desk-top   quality  full  VGA  color  image  that  is
approximately  equivalent  to  that  of a  15"  VGA  monitor  at a  distance  of
approximately two feet. We also offer an optional  light-weight,  6.4 inch, full
VGA color, flat panel display, with integrated  digitizer,  for users who do not
desire an HMD or do not need to be 100%  hands-free  and  feet-free  to  perform
their job.  The  body-worn  computing  unit is  designed to allow  operation  in
environmental  conditions in which  conventional  portable  computers  could not
previously  operate,  weighs  less than two  pounds  and is  capable  of running
software applications  designed for Microsoft(R)  Windows(R) 3.11, Windows(R) 95
and 98, Windows(R) NT(TM), DOS, SCO UNIX(R) and LINUX.

         We   currently   offer  two  novel   software   products  to  get  user
documentation  up and running on the Mobile  Assistant  quickly.  The  following
products  can be used on the  Mobile  Assistant(R)  or  conventional  desktop or
laptop computers:

         o    linkAssist(TM) allows users to link information quickly regardless
              of the format of the data or where it is stored, avoiding the need
              to change,  convert or reenter the existing  information or to use
              the very technical HTML tagging process. An interesting and useful
              feature of this  product is that the linked  words or phrases  can
              then be activated by voice automatically, with no development work
              by the author of the documentation or databases.

         o    webAssist(TM)  allows voice navigation of HTML document links such
              as those  found on web sites on the World Wide Web and  intranets.
              This software  provides the user with hands-free  access to all of
              the information  found on, for example,  manufacturer and supplier
              and company-owned, web sites.

         Additional authoring and inspection toolkits are in development and are
expected to available this calendar year.

Industry Overview

         There has been an ongoing evolution in computer hardware to reduce size
and increase  performance and functionality  since the introduction of the first
large mainframe computers in the 1950's. The
    
                                     - 26 -

<PAGE>
   


commercialization   of  mobile  computing  products  combined  with  significant
increases  in the number and scope of software  applications  has  resulted in a
multi-billion  dollar  market.  We see the next  phase in this  evolution  to be
body-worn, voice-activated computers, which will provide hands-free portability.
We believe the substantial  historic and projected growth in all forms of mobile
and portable  computers  will  translate  into the  development of a substantial
market for our mobile  computing  hardware and software  products.  According to
MarkIntel,  a service  which  compiles  market  research  reports,  the  overall
portable  computer  market (20 pounds or  lighter)  will have an average  annual
growth in revenues  of  approximately  13% to over $23 billion  through the year
2000. MarkIntel also reports that:

        o     notebook  computers (i.e. weighing  from 5  to 8 pounds) currently
              constitute over 70% of portable units sold;

         o    sub-notebook  computers  (3  to  5  pounds)  currently  constitute
              approximately 15% of sales of portable  computers and are expected
              to increase to almost 19% of sales by the year 2000; and

         o    mini-computing  and  communication  devices (3 pounds or less, and
              which still are  considered to be in an  evolutionary  cycle) will
              experience an average annual revenue growth rate of 33%.

         The  computer  software  industry  has  undergone  a similar  evolution
evident in a shift from processing data to providing  information in conjunction
with the changes in computer  hardware.  For example,  mainframe  computers were
initially  used to process vast amounts of data such as  population  statistics,
corporate  accounting  information,  etc. However,  with personal computers came
software to provide information to users in the form of analysis, relationships,
etc. We believe that  providing  "how to" knowledge to users is the next step in
the evolution of the computer  software and one that is well suited for use with
body-worn computers.

Business Strategy

         Our  objective  is to  be  the  leading  provider  of  voice-activated,
hands-free  mobile  computing  systems and  related  software.  To achieve  this
objective, we intend to pursue the following strategies:

         Develop and Strengthen  Strategic Alliances.  We have established,  and
intend  to  continue  to  establish,   strategic   alliances  with   world-class
distribution  partners,  selected  systems  integrators,   independent  software
vendors,  VARs,  OEMs  and  industrial  and  commercial  equipment  and  service
providers.  The benefits we receive from these associations  include access to a
larger  potential  customer base,  complementary  technologies,  reduced capital
investment through utilization of outside resources, and access to manufacturing
expertise and efficiencies of world-class  manufacturers.  We have  distribution
and support  agreements with EnPointe for North American  distribution,  Hewlett
Packard for European, Middle East and African distribution and support, and with
Nissho  Iwai  for Far East  distribution.  All  agreements  have  resulted  in a
worldwide  distribution  network to be operational this calendar year to support
the launch of the MA IV Series.  In addition,  we have already  contracted  with
certain  large   systems   integrators,   such  as  DynCorp,   to  both  provide
implementation  support  for our  customers  worldwide  as well as to place  our
products within their own client bases. We have been pursuing, and will continue
to pursue,  additional  strategic  associations to enhance our product offerings
and expand our marketing activities.

         In addition to marketing and establishing strategic  relationships,  we
have contracted with  organizations  such as the SBS in Europe (over 30 software
companies  serving as a Xybernaut  Center of Excellence  for speech and wearable
applications),  and companies in the USA and Asia for hardware  development  and
field testing of application-specific solutions.

         Provide Custom Software Solutions for Diverse Customer Needs. We intend
to  continue  the  development  or  acquisition  of  software  that  enables our
customers to create  customized  software  applications  for use with the Mobile
Assistant(R)  Series and on  conventional  PCs. We will design this  software to
provide  prepackaged  application  expertise  that  incorporates  the end user's
existing programs, procedures and technical
    
                                     - 27 -

documentation,    thereby   permitting   the   cost-effective   development   of
productivity-enhancing  software  applications  by  customers.  We believe  that
revenue from software will become an important  contributor to operating margins
in the future.

         Penetrate Target Markets Through Licensees,  OEMs, VARs,  Distributors,
and Direct Sales. We believe that our mobile computing  technology is especially
well  suited  for the repair  and  maintenance  of  commercial,  industrial  and
military   equipment   and   facilities.   We  also  believe  that   forms-based
applications,  such as inventory and data collection,  are extremely well-suited
for our flat panel display configuration, requiring the user to carry only a 1 -
1 1/2 pound VGA color  display/digitizer  instead of heavier pen  tablets  which
offer only limited  computing  power.  We intend to penetrate our target markets
through   effective  use  of  OEMs,  VARs  and  distributors   that  demonstrate
comprehensive  market knowledge in their markets. We intend to leverage internal
marketing and sales  resources,  and achieve  rapid foreign and domestic  market
penetration  through  the  use  of  already  approved,  as  well  as  additional
distributors,   systems   integrators,   industrial  and  commercial   equipment
suppliers,  independent  software  suppliers,  OEMs and VARs.  We also intend to
continue  marketing directly to key national accounts in order to build multiple
reference  accounts so that our  distributors may quickly expand their own sales
world-wide. These reference accounts also provide our research,  development and
engineering  organizations with valuable  unfiltered feedback from customers for
future product development.  We expect to have numerous opportunities to license
our intellectual property as large computer and equipment  manufacturers attempt
to enter the wearable or user-supported  computing marketplace.  We believe such
licensing  will  yield  significant   revenue  as  well  as  accelerated  market
penetration.

         Achieve  and  Maintain  Technology  Leadership.  We  are  committed  to
achieving and maintaining  technological  superiority of the Mobile Assistant(R)
Series and our other mobile computing hardware and software products through the
continuous   reassessment  of  product   performance  and  the  utilization  and
integration of state of the art hardware and software  technologies.  We believe
that our  substantial  expenditure  of time and effort in developing  the Mobile
Assistant(R)  Series has resulted in a set of core competencies which provide us
with a solid foundation in the hands-free,  mobile computing industry. We intend
to maintain this advantage through ongoing research and development,  which will
ensure that the Mobile Assistant(R) Series will continue to provide a full range
of PC  capabilities,  including  two-way video  communication  and access to the
Internet,   intranets,   remote  databases  and  other  computerized   reference
resources.  We also  intend  to rely  heavily  on  joint  developments  with our
strategic partners worldwide,  and cross-licensing of our valuable  intellectual
property  to build and  market new  technology.  The  current MA IV Series,  for
example,  is the  result of our  successful  relationships  with  Fujitsu,  Sony
Digital Products, Hitachi, Shimadzu, Toshiba, JAE and Moli Energy, all under the
auspices of our Japanese operations.

         Commitment to Open  Architecture.  We utilize  standard PC hardware and
software  architectures and design our products using open systems technologies,
including   industry  standard   operating  systems  and  open  system  computer
platforms.  We continually  evaluate the feasibility of integrating our software
and hardware  products with new technologies as these are developed and accepted
in the marketplace.  We anticipate upgrading our current products to incorporate
open architectures to allow use with existing and emerging standards in hardware
and software technology.

         Leverage Core  Competencies.  We believe our core  competencies are the
integration  and  adaptation  of  innovative   computer  hardware  and  software
technologies  into hands-free  mobile  computing  products that enhance end-user
productivity.  We will seek to expand  applications  for our technologies and to
capitalize  on the breadth of our  expertise by assisting  our  customers in the
development  of  new  hardware  and  software  products.  Consistent  with  this
strategy,  we will  continue  to  focus  on  integration  of  hands-free  mobile
computing hardware with internally developed, or acquired, software applications
and  hardware  products.  Our goal is to adhere to the model of an  Intellectual
Property-Virtual   Hardware-Communications-Software  Company,  concentrating  on
research,  development and engineering,  and marketing strategies.  We intend to
continue to allow our strategic partners to execute our manufacturing,  service,
sales and  marketing  functions,  under the watchful eye of our  management.  We
intend to remain  small and nimble,  able to react  quickly to market  needs and
world economic changes.

features:

         1.  Compact, lightweight and rugged hardware  specifically designed for
             mobile, body-worn use

         2.  Easy to use human interface

         3.  Voice command control

         4.  Head-worn miniature display

         5.  Flat panel miniature display/digitizer

         Compact  Hardware  for  Mobile,  Body-Worn  Use.  The  MA IV  currently
utilizes  primarily  off-the-  shelf  miniaturized   hardware  components  in  a
body-worn  computing package weighing under two pounds.  Design features for the
MA IV currently include:

          o   Intel Pentium (R)200 or 233 MHZ processor w/ 512 KB L2 cache.

          o   Extended Data Output  ("EDO") RAM (currently ranging from 32 Mb
              to 128 Mb).

          o   Internal hard disk currently ranging from 2 - 4 GB.

          o   Protected  internal  dual PC Card  readers  using  CardBus
              (industry-standard peripheral cards).

          o   Enclosure   to  allow  use  in  a   wide  range  of  environmental
              conditions.

          o   Advanced-technology, hot-swappable lithiumion battery and charger.

          o   HMD/FPD, USB, Power and Replicator ports.

         Voice  Command  Control.   The  Mobile   Assistant(R)  Series  supports
state-of-the-art   voice  recognition  software,   hardware  and  algorithms  to
communicate  digitized  speech as input to the  processor  through an integrated
analog-to-digital/digital-to-analog   circuit.   Generally,   significant   user
training is not required  because the operable  vocabulary is created in advance
to be recognized by a wide range of users or a phonetic engine is utilized.  The
system can also be programmed to "learn" the user, on the fly, during  real-time
field  use.  The  speaker-independent  approach  works  well  for the  menu  and
button-driven  programs used in the Mobile Assistant(R).  System accuracy can be
improved  greatly  since the  words and  phrases  for each  menu  screen  can be
predetermined  and used to limit  recognition  ranges to the screen at hand. The
combination of voice  recognition and head-worn display provides the user of the
Mobile  Assistant(R)  with  hands-free  access to information and the ability to
apply this  information  to operations  and tasks with direct lines of sight and
tactile access. In addition to basic command-and-control speech recognition, the
MA IV also offers dictation features,  and natural language speech processing is
planned for introduction in 1999. Our main speech  development  partners are IBM
and Texas Instruments.

         Head-Worn Miniature Display.  The MA IV uses a lightweight HMD with 640
X 480 pixels (VGA color). It is anticipated that this display will be offered in
color SVGA, 1280 X 1024 pixel  resolution,  and eventually in color  resolutions
exceeding those planned for  High-Definition  TV. All displays are approximately
one square inch in size and use advanced  optics to present an image to the user
that is  equivalent  to a 15" desktop  monitor at a distance of two feet.  These
displays are available in monocular  form, and can be worn on a mounting  device
similar to a runner's  visor,  or on helmets,  hardhats,  soft  baseball caps or
similar headgear. These high quality,  miniature displays present information in
a heads-mounted display format without completely occluding vision.

         Flat Panel Display. The MA IV uses an optional light-weight,  6.4 inch,
full VGA color, flat panel display, with integrated digitizer,  which is offered
for users  who do not  desire  an HMD or do not need to be 100%  hands-free  and
feet-free to perform their job.

         Computer   Software  for  Mobile,   Body-worn  and  Desk-top  Use.  Our
linkAssist(TM)  and  webAssist(TM)  products  are  ready  for  the  market.  See
"--Information About Our Products."

         We also have two other  products under  development  and expect to have
them ready for the market in 1999. All products,  while designed to speed up the
development  of  applications  for our line of wearable  computers,  are equally
applicable to lap-top and desk-top applications. Our two software products under
development are:

         o        Mobile  Inspector(TM) - a toolkit to assist  developers in the
                  creation of inspection  applications regardless of whether the
                  item under  inspection  is a car,  a furnace or a human  body.
                  This toolkit,  already proven  without  speech  navigation and
                  entry  features,  is being updated to  incorporate  our speech
                  recognition software offerings.

         o        The second product, as yet unnamed, is an authoring toolkit to
                  quickly  create  Interactive   Electronic   Technical  Manuals
                  (combinations  of expert  software  and  electronic  books and
                  drawings and charts) and on-the-fly training programs.

Marketing and Sales

Markets

         We design our marketing efforts to increase awareness of and demand for
our products in the commercial,  industrial and military markets.  The following
are examples of selected  horizontal and vertical  markets which we will address
in our continuing marketing efforts:
    

                                     - 30 -

         Commercial Maintenance and Repairs.  Information from the United States
Bureau of Labor  Statistics and Bureau of Census indicates that as of 1996 there
were more than  5,460,000  commercial  mechanics and  technicians  in the United
States; all of which, we believe, are potential users of the Mobile Assistant(R)
Series and our other products.  There are many sources of savings available from
use of the Mobile  Assistant(R) Series and our other products in maintenance and
repair  operations such as: less formal training is required for a similar level
of performance,  the time required for diagnostic and repair tasks is reduced as
"just in time"  refreshers and improved  technical  information can be provided,
and  personnel  can address a wider range of complex  tasks or products with the
same level of basic  training.  While  these  savings  can be  realized  in most
industries, we anticipate that these savings will be most immediate and apparent
in those  industries that require a large investment in equipment and machinery,
including the transportation, automotive, construction, power generation, health
services,  agriculture  and the military.  In industries such as construction or
mining, we believe downtime on critical equipment can cost up to $75,000 or more
per day.  Accordingly,  a reduction  measured in minutes or hours of downtime in
these industries can, in our view, provide ample cost justification for a Mobile
Assistant(R).  The  telecommunications  industry  is  expected  to  be  a  prime
candidate   for  mobile   computing   systems  given  the   industry's   complex
technologies,  increased  competition  and assets spread over a wide  geographic
area. The Mobile Assistant(R) can provide needed knowledge to workers on the top
of a telephone  pole,  at a remote relay  station or in a conduit  tunnel.  Crew
locations  can be  monitored  and  coordinated  in the  field  with  the  Mobile
Assistant(R)  through optional global positioning  system  technology.  Crews at
remote  locations  can consult with  experts  using  two-way  audio and/or video
communications.

         Healthcare.  According to the National Center for Health Statistics, in
the United States spent  approximately 13.6% of the U.S. Gross Domestic Product,
or  approximately  $1 trillion,  on  healthcare,  with an estimated  25% of such
expenses consumed by administrative  expenses.  According to the National Center
for Health  Statistics,  United  States,  1994, the United States has over 6,000
hospitals and over 540 health maintenance organizations. According to the United
States  Department  of  Labor,  in  1994  there  were  approximately   4,714,000
healthcare  workers in the United  States.  We believe  that many of the current
processing and data systems used in healthcare,  both in institutions and in the
field, are not well developed or integrated and that hands-free mobile computing
systems  could reduce  expenses and increase  efficiency in this  industry.  The
Mobile  Assistant(R)  is believed to present  great  potential in field  medical
operations  by  providing  on-board and remote  diagnostics,  audio and/or video
communication  with  doctors  for  emergency  procedures,  and  transmission  of
locations for helicopter pickup through global  positioning  systems  integrated
into the Mobile  Assistant(R).  Another  anticipated  benefit of our  hands-free
mobile computing  technologies is that fewer healthcare personnel will be needed
to perform complex tasks. By providing  remote delivery of medical  information,
our hands-free  mobile computing  systems can become a key component within both
managed  care  and  telemedicine  organizations,  which  are two key  submarkets
developing within the healthcare industry.

         Public Sector.  We have  demonstrated  the ability of our technology to
aid in law  enforcement,  fire  protection,  emergency  services  and control of
national borders. EnPointe, the North American distributor of Xybernaut's MA IV,
has  demonstrated  the success of  establishing  purchasing  schedules  for most
significant  city,  state and  municipal  agencies,  thus making the  technology
readily available.

         Education. We believe that our mobile computing systems are well suited
for educational  applications.  The Mobile Assistant(R) is especially suited for
hands-free applications, such as laboratory work, field research and dissections
and has the potential to serve as a mobile student workstation.  In addition, it
can provide an ideal  computing and control  platform for special  education and
handicapped needs.

         Military.  There are several  potential  military  applications for our
hands-free mobile computing  systems,  including  intelligence,  maintenance and
field  operations.  The military has long been an early user of advanced weapons
technologies  and,  as a result,  was one of the  first  sectors  to  experience
problems  with the ability of  personnel  to  maintain,  diagnose and repair the
advanced technology employed in both weapons and equipment.  These problems have
been  compounded by the  downsizing  of the United  States  military and related
budget  constraints.  As a result, even greater pressure will be placed upon the
military to maintain its equipment and weapons  platforms with fewer  personnel.
We believe that most of the estimated 700,000 military maintenance
    
                                     - 31 -

<PAGE>
   


personnel in the United States could be made more  efficient  and  productive by
our hands-free mobile computing systems.

         The United States military's increasingly  sophisticated weapon systems
require  volumes of  operational  and  technical  manuals and have  dramatically
increased the  importance of  maintenance.  The United States Army has purchased
the Mobile  Assistant(R) and has tested its use in the maintenance and repair of
the AH64 Apache Attack helicopter.  The Apache can send and receive  maintenance
data via an  industry  standard  electrical  interface  which  can be read by an
optional interface for the Mobile  Assistant(R).  Operating and performance data
can be downloaded  directly from the Apache and the Mobile  Assistant(R)  can be
used to diagnose  existing and potential  maintenance  and repair  problems.  We
anticipate  that  manufacturers  of complex  military and  commercial  equipment
increasingly  will  incorporate  integrated  data  collection  and  transmission
capabilities into their technologies to reduce downtime,  repair and maintenance
related costs.

         The  ability  to  deliver  information  to  soldiers  in  combat  field
operations is the focus of several development  programs sponsored by the United
States Army.  The Army has been  conducting  simulated  combat  maneuvers  using
body-worn  computing  components,  including  those  we  provide,  to  determine
effectiveness for use in coordinating troop locations and movements, determining
enemy locations, and using global positioning systems to provide coordinates for
artillery, helicopter pickup and air support.

         We have sold many systems to the US Army and Navy,  and expect that our
sales  partners  will sell heavily into the armed  services  both in the USA and
overseas.

Marketing

         Because our products are  frequently  combined with products from other
manufacturers to form integrated information systems, we believe that it is more
effective  to  sell  principally  through  distributors,   systems  integrators,
industrial and Commercial equipment manufacturers,  independent software vendors
and VARs with defined market niche expertise and presence.

         In preparation  for the  introduction  of the MA IV, we have contracted
with several  specialized  distributors for higher volume distribution of the MA
IV. We believe  that by forming  relationships  with these  partners we can gain
entry to many various sub-markets and types of end users, and serve customers or
have in-place  sales and  distribution  channels that identify new customers and
sales  opportunities.  We can then reach end users more  rapidly in a variety of
industries.

         To ensure outstanding partner  performance,  we offer detailed in-house
training  sessions to prepare and update personnel for field sales and training.
In addition, we are developing  comprehensive sales and operations manuals to be
used by these channels and end-users.

         Our marketing  and sales  employees are  responsible  for  implementing
direct  marketing plans and sales programs,  coordinating  sales activities with
sales and marketing and service  partners.  All fulfillment will be accomplished
through  distribution  partners,  regardless  of which  entity  makes the actual
sales.

License Granted to the Company by Data Disk

         During 1997,  we entered  into a series of  agreements  with  Data-Disk
Technology,  Inc., a Virginia-based company. Data-Disk Technology, Inc. produces
the Data Disk, a memory  product  that  consists of a  non-volatile  memory chip
encapsulated  in a rugged  polymer  casing  slightly  smaller  than a  soldier's
"dogtag" that is highly resistant to temperature and  environmental  conditions.
We believe that the Data Disk  provides an ideal  storage  medium for  body-worn
computer  applications,  especially those that involve a large number of people,
inspection sites or equipment.  These tags can be used to store information such
as medical  history,  repair  history or other data unique to an  individual  or
piece of  equipment.  Such  information  can be read by inserting the tag into a
reader  that fits in the  existing  PC card  slots on all  models of the  Mobile
Assistant(R). The U.S. Department of
    
                                     - 32 -

<PAGE>

   

Defense is evaluating  the Data Disk and competing  technologies  to replace the
current system of stamped metal dogtags for soldiers.  Under the agreements with
Data Disk, we received an exclusive, perpetual worldwide license to use and sell
present and future Data Disk technology for user-supported  (wearable) computing
applications.

Key Suppliers

         We have supplier relationships with Sony Digital Products and Shimadzu,
among others, for the production of the MA IV system. (See  "--Production").  We
have  designed  a  proprietary  HMD  that  is  being  manufactured  by  Greenway
Engineering  using  purchased and fabricated  parts.  We contracted  Greenway to
purchase and manage parts and components inventory, manufacture computer boards,
and assemble and test the HMD of the Mobile  Assistant(R),  as well as to obtain
Federal  Communications  Commission  certification  for the Mobile  Assistant(R)
system.

         We have also  entered  into  design,  production,  supply  and  support
agreements  with many companies,  in the USA and overseas,  in order to complete
our wearable line of computers.  They include  Fujitsu,  Sony Digital  Products,
Hitachi,  Shimadzu, JAE, Toshiba, Moli Energy, IBM, Texas Instruments,  the SBS,
etc.

         We  currently  have  subcontracted  the  manufacture  of the  body-worn
computing unit, headset and battery portions of the 133P to third-party vendors.
These components are assembled and integrated with the software applications for
the Mobile Assistant(R) at our headquarters.

         Although  we  believe  there are  multiple  sources  for many parts and
components, we depend heavily on our current suppliers. While we believe that we
could adapt to any supply  interruptions,  such  occurrences  could  necessitate
changes in product design or assembly methods for the Mobile Assistant(R) Series
and cause us to experience  temporary  delays or  interruptions  in supply while
such  changes  are  incorporated.  Further,  because  the order time for certain
components may range up to approximately  three months, we also could experience
delays or  interruptions  in supply in the event we are  required  to find a new
supplier for any of these  components.  Any  disruptions  in supply of necessary
parts and components from our key suppliers could have a material adverse effect
on our  results of  operations.  Any future  shortage or limited  allocation  of
components for the Mobile  Assistant(R)  could have a material adverse effect on
our operations, cash flows, and financial condition.

Production

         We are party to a manufacturing agreement with Sony Digital Products, a
subsidiary of Sony  Corporation  based in Nagano,  Japan, for the manufacture of
the MA IV,  which is  scheduled to begin  pre-production  in the quarter  ending
December 31, 1998. We have been engaged by Shimadzu  Corporation,  a supplier of
head- mounted displays and other commercial  technology products based in Kyoto,
Japan to develop and manufacture a color HMD for use with the MA IV. Most of the
parts  and  components  for  the  Mobile  Assistant(R)  are  off-the-  shelf  PC
components  that are  available  in high  quantity  from  multiple  vendors.  We
currently use a monochrome  Active Matrix Liquid Crystal Display  ("AMLCD") from
one  supplier  in its HMD.  We have  been  notified  by that  supplier  that the
monochrome  AMLCD has been  discontinued and is being replaced by a color AMLCD.
We believe that there are  sufficient  quantities  available of this  monochrome
AMLCD to meet currently  forecast  requirements for the 133P system until the MA
IV system is  introduced.  If the start of  full-scale  production  of the MA IV
model of the Mobile Assistant(R) is delayed past the quarter ending December 31,
1998,  such delay will have an adverse  effect on revenues for the twelve months
ending December 31, 1998. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."

Warranties

         We  provide  customers  with a parts and labor  warranty  for one year.
Warranty  services for the 133P are provided by Matrix and warranty services for
our HMD are  provided by Greenway  Engineering,  except for the AMLCD,  which is
provided  by its  manufacturer.  Warranty  services  for the MA IV  Series is an

offering by several  vendors.  Our  distribution  partners are  responsible  for
levels  one and two  service.  We  intend  to pass on  Level 3  maintenance  and
call-center support to a 3rd party service firm.

Competition

         We  anticipate  that we will face  widespread  competition  from  other
portable  computing systems  manufacturers.  Several other companies,  including
Computing Devices International,  a division of Ceridian Corporation,  ViA Inc.,
Texas  Microsystems,  Telxon,  Norand and  Teltronics,  Inc.,  a  subsidiary  of
Interactive  Solutions,  Inc.,  Raytheon and a consortium of Litton and TRW, are
engaged  in  the  manufacture  and  development  of  body-mounted  or  hand-held
computing systems that do or could compete with the Mobile Assistant(R)  Series.
Personal digital  assistants and laptop and notebook computers also are products
that  could  compete  against  the Mobile  Assistant(R)  in  applications  where
hands-free,  voice-activated  operation is not required. Many of these computers
are  manufactured  by major domestic and foreign  computer  manufacturers  which
possess  far more  resources  than we do and which can be  expected  to  compete
vigorously  with us.  However,  we consider  entry by reputable,  large computer
manufacturers  to be  healthy  for  the  marketplace  in  that  it  would  bring
legitimacy to the market in a more rapid fashion.

Intellectual Property

         We consider our patent, trade secrets, and other intellectual  property
and proprietary  information to be important to our business prospects.  We rely
on a  combination  of patent,  trade secret,  copyright  and trademark  laws and
contractual  restrictions  to establish and protect our proprietary  rights.  We
have implemented a trade secret management  program to protect our trade secrets
and proprietary information.  In addition, we have confidentiality and invention
assignment   agreements   with  our   employees,   and   generally   enter  into
non-disclosure  agreements  with  our  suppliers,  VARs,  OEMs  and  actual  and
potential  customers  to  limit  access  to and  disclosure  of our  proprietary
information.

         We have registered our Mobile Assistant(R) and Xybernaut(R)  trademarks
on the Principal  Register of the United States Patent and Trademark  Office and
the patent and trademark offices in several foreign countries. In April 1994, we
obtained U.S.  patent number  5,305,244  ("hands-free,  user-supported  portable
computers") for the Mobile  Assistant(R)  Series. We derived most of our revenue
for the twelve months ended  December 31, 1997 and 1996 and the six months ended
June 30, 1998 and 1997 from products included within the scope of the Patent. We
have notified  several of our competitors of the existence of the Patent,  which
our counsel  believes may have been  infringed by some of such  competitors.  We
intend  to take  any and  all  appropriate  measures,  including  legal  action,
necessary to maintain and enforce our rights under the Patent and other  patents
held by us.

         We have filed twenty patent  applications  covering  various aspects of
computers in general and wearable  computers in particular  since July 1996. Six
of these  patent  applications  have been  issued,  one patent has been  allowed
pending  issuance and thirteen  patents are pending.  We have also filed most of
these applications in European countries, The People's Republic of China, Japan,
Republic of Korea, Republic of China (Taiwan), Canada and Australia. All patents
issued to our employees under pending and future applications have been and will
be assigned to us under existing invention assignments.

         We cannot assure you that our pending patent applications will issue as
patents,  that any issued  patent will provide us with  significant  competitive
advantages or that  challenges  will not be  instituted  against the validity or
enforceability  of any of our  patents.  The cost of  litigation  to uphold  the
validity and prevent  infringement  of patents can be  substantial.  We also can
provide no assurance that others will not independently  develop similar or more
advanced products,  design patentable  alternatives to our products or duplicate
our trade  secrets,  or that our  employees or  suppliers  will not breach their
confidentiality  agreements.  In addition, we may be required, in some cases, to

Research and Development

         Our research and development  expenditures for the years ended December
31,  1997  and 1996  and the six  months  ended  June  30,  1998  and 1997  were
$2,350,237,   $1,773,015,   $1,010,769  and  $1,196,319,   respectively.   These
expenditures  consist  primarily of personnel engaged in the research and design
of new  hardware  and  software  products,  test  components,  consulting  fees,
equipment  and  purchase  software  costs  required to conduct  our  development
activities.

Employees and Consultants

         As of June 30, 1998, we had 30 full-time and nine part-time  employees,
and had  consulting  arrangements  with ten  individuals or firms for advice and
assistance on selected  technical and business  issues.  Of our thirty full-time
employees,  two are executive officers,  eleven are technical and administrative
support  employees,  five are  engaged in  research  and  development,  four are
engaged in assembly  and  testing and eight are engaged in sales and  marketing.
None of our employees are  represented by a union. We believe that our relations
with our employees are good.

         We are party to employment  and consulting  agreements  with certain of
our executive officers and directors.  See "Management -- Employment Agreements;
- -- Consulting Agreements."

Properties

         Our office and  development  facility  consists  of 18,642  square feet
located at 12701 Fair Lakes Circle, Fairfax,  Virginia. Our current lease is for
a three-year  term  expiring  September  30, 1998 and  requires  monthly rent of
approximately $26,000.

         To minimize lodging expenses for visiting employees and consultants, we
lease an apartment located at 4401 Sedgehurst  Drive,  #301,  Fairfax,  Virginia
22033 pursuant to a month-to-month lease requiring monthly rent of $975. We must
give at least 45 days prior written notice before  termination of the lease.  We
also lease an apartment at 11842 Federalist Way for a twelve-month period ending
November  30, 1998 with a monthly  rent of $1,099 and an apartment at 4705 Quiet
Woods Lane for a twelve-month  period ending July 6, 1999 with a monthly rent of
$1,016.

         During the year ended  December 31, 1997, we leased  approximately  650
square feet of office space at FM Building  102,  7-39-5  Nishikamata,  Ohta-ku,
Tokyo 144, Japan,  for use as our Far East  representative  office.  The initial
lease term is for two years  ending  April 1999 at a base rent of  approximately
$1,700  per month and is  renewable  at our option  for an  additional  two year
period.  Subsequent to year-end,  we terminated this lease and moved our offices
to Wakadayashi Building, 5-12-6 Kita-Shinagawa, Shinagawa-ku, Tokyo 141, Japan.

Legal Proceedings

         On March 19, 1998, Matrix Corporation,  with whom we had entered into a
June 1997 agreement (the "June  Agreement"),  filed a summons  against us in the
United States District Court, Eastern District of North Carolina, alleging that:

         o        we damaged Matrix by our purported breach of the December 1997
                  Agreement (the "December Agreement");

         o        we  should  return  all goods shipped by Matrix under both the
                  June Agreement and the December Agreement; and

         o        we did not intend to comply with the  December  Agreement  and
                  therefore  the  governing  contract  between the two  entities
                  should revert to the June Agreement.

<PAGE>
   


         In addition,  this summons requests that any damages incurred by Matrix
as a result of this purported breach of contract be trebled.  On August 6, 1998,
the Court rendered an Order  dismissing all of Matrix's  claims,  except for the
breach of contract claim under the December Agreement.  On September 9, 1998, we
filed an answer which  denies the material  allegations  of the  complaint,  and
asserts  a   counterclaim   alleging  that  Matrix  failed  to  perform  to  the
requirements  of the December  Agreement and that  Xybernaut has been damaged by
this failure to perform.  While there can be no assurance of the outcome of this
legal  proceeding,  we believe that the remaining  claim by Matrix is groundless
and that the impact of this legal  proceeding will not be materially  adverse to
our operations. The maximum amount which we would have to pay under the December
Agreement if Matrix  performs  defined tasks is  approximately  $250,000 and the
maximum amount of inventory that we could assume under the December Agreement is
approximately $600,000.

         None  of the  foregoing  options  were  exercisable  within  60 days of
December 31, 1997.

         We do not have a retirement,  pension or profit sharing program for the
benefit of our directors,  officers or other  employees.  The Board of Directors
may recommend one or more such programs for adoption in the future.

Employment Agreements

         We have an  employment  agreement  with Edward G. Newman  which has the
following terms:

         o    a three-year term through December 31, 1998;
         o    initial annual base  compensation of $150,000 subject to a minimum
              annual increase to $198,000 on January 1, 1997 and of at least the
              annual  increase in the United States Consumer Price Index ("CPI")
              plus two percent annually thereafter;
         o    an annual cash bonus in an amount to be determined by the Board of
              Directors;  and o a $2,000,000  life  insurance policy  payable to
              his designated beneficiaries.

         Mr. Newman received  payments in 1997 for accrued salaries and expenses
related to his employment  with Tech Virginia and continues to provide  services
to Tech Virginia  without contract at a fixed payment of $1,000 per month with a
$650 automobile  allowance per month.  The employment  agreement with Mr. Newman
also  entitles  him to  participate  in all  benefits  which we may offer to our
executive  officers and employees,  as a group. We anticipate that such benefits
will include an  automobile,  health  insurance and expense  reimbursement.  The
employment  agreement  automatically  renews for an additional  three-year  term
unless  terminated in writing by either party on or before October 31, 1998. The
employment  agreement also provides for  termination at the option of Mr. Newman
in the event of a change of  control  (which is  defined  as Mr.  Edward  Newman
ceasing to serve as either the Chairman of Board of  Directors or our  President
and Chief  Executive  Officer) and that upon any such  termination Mr. Newman is
entitled  to at least  two  years of annual  compensation  under his  employment
agreement.

         We employ Mr. Toyosato  pursuant to a three-year  Employment  Agreement
with a term expiring on March 3, 2000. The Employment  Agreement provides for an
annual salary of $153,575.23.

Consulting Agreements

         We have a  consulting  agreement  with Dr.  Steven  Newman  dated as of
January  1, 1996,  as  amended  January  1,  1997.  Pursuant  to the  Consulting
Agreement,  Dr. Newman provides consulting services which include the review and
assistance in the  preparation  of our business  strategies,  assisting with the
recruitment and hiring of key executives and provide advice regarding financing,
contracting,  management, overseas operations, strategic alliances and ventures.
The annual consulting fee is $150,000 payable on a monthly basis. The Consulting
Agreement  also  provides for  additional  compensation,  as  determined  by our
Compensation  Committee,  for  services  by Dr.  Newman in  connection  with the
successful completion of financings, mergers, acquisitions,  dispositions, joint
ventures and other material  transactions.  The term of the Consulting Agreement
is four years terminating on December 31, 2000 unless renewed by the parties.

         In 1996, we entered into a two-year consulting agreement with Victor J.
Lombardi  whereby  Mr.  Lombardi  agreed to  provide  business  development  and
marketing  services to us in exchange for warrants which entitle Mr. Lombardi to
purchase  100,000 shares of Common Stock at $6.00 per share through December 31,
1999.  For the year ended  December  31, 1997,  we recorded  $125,489 in expense
connected with the issuance of these warrants.

Compensation of Directors

         We do not  pay  or  accrue  salaries  or  consulting  fees  to  outside
directors  for  each  board  or  committee  meeting  attended.  While  it is our
intention to establish such payments eventually,  we do not currently anticipate
doing so. Any payments  when  implemented  will be  comparable  to those made by
companies  of similar size and stage.  Directors  receive a grant of options for
50,000 shares of Common Stock upon election to the Board of Directors.  They are
also entitled to receive a grant of options to purchase  10,000 shares of Common
Stock  which  vests at the end of such  year of  service  for each  full year of
service. We commenced this practice with those directors who were elected at the
1997 Annual  Meeting,  We adopted an Omnibus Stock  Incentive  Plan and the 1997
Stock  Incentive  Plan in which  directors  are  eligible  to  participate.  See
"Executive  Compensation - Omnibus Stock Incentive Plan; -- 1997 Stock Incentive
Plan." We have a consulting agreement with Steven A. Newman.
See "Executive Compensation --Consulting Agreements."

Omnibus Stock Incentive Plan

         The Board of Directors  adopted the 1996 Omnibus Stock  Incentive  Plan
(the "1996 Incentive Plan")  effective  January 1, 1996. The 1996 Incentive Plan
provides for the granting of incentive stock options ("Incentive Stock Options")
within the  meaning of Section  422 of the  Internal  Revenue  Code of 1986,  as
amended (the "Code"),  nonqualified  stock options,  stock  appreciation  rights
("SARs")  and grants of shares of Common Stock  subject to certain  restrictions
("Restricted  Stock") up to a maximum of 650,000 shares to officers,  directors,
employees  and  others.  Incentive  Stock  Options  can be  awarded  only to our
employees.  No options,  SARs or restricted  stock  ("Restricted  Stock") may be
granted under the 1996 Incentive Plan  subsequent to December 31, 2006. To date,
we have granted  options to purchase  all of the 650,000  shares of Common Stock
reserved for issuance under the 1996 Incentive Plan.

         The Compensation Committee administers the 1996 Incentive Plan (subject
to the  authority  of the  full  Board of  Directors).  The  Board of  Directors
determines  the terms and conditions of the options,  SARs and Restricted  Stock
granted under the 1996 Incentive Plan,  including the exercise price,  number of
shares  subject to the  option and the  exercisability  thereof.  Dr.  Steven A.
Newman,  Lt.  Gen.  Harry E.  Soyster  (Ret.) and  Martin  Eric  Weisberg,  Esq.
currently are the members of the Compensation Committee.

         The exercise  price of all Incentive  Stock  Options  granted under the
1996  Incentive  Plan must  equal at least the fair  market  value of the Common
Stock on the date of grant. In the case of an optionee who owns stock possessing
more than ten percent of the total combined voting power of all classes of stock
("Substantial Stockholders"), the exercise price of Incentive Stock Options must
be at least 110% of the fair  market  value of the  Common  Stock on the date of
grant.  The exercise price of all  nonqualified  stock options granted under the
1996 Incentive Plan shall be determined by the Compensation Committee.  The term
of any Incentive  Stock Option  granted  under 1996 the  Incentive  Plan may not
exceed ten  years,  or,  for  Incentive  Stock  Options  granted to  Substantial
Stockholders,  five years.  The 1996 Incentive Plan may be amended or terminated
by the  Board of  Directors,  but no such  action  may  impair  the  rights of a
participant under a previously granted option.

         The  1996  Incentive  Plan  provides  the  Board  of  Directors  or the
Compensation   Committee  the  discretion  to  determine  when  options  granted
thereunder shall become exercisable and the vesting period of such options. Upon
termination of a participant's employment or relationship, all options terminate
and no longer are exercisable  unless termination is due to death or disability,
in which case the options are exercisable  within one year of  termination.  The
Compensation Committee has granted extensions of the period before which options
may be exercised for certain terminated employees.

         The 1996  Incentive  Plan provides  that upon a change in control,  all
previously granted options and SARs immediately shall become exercisable in full
and all Restricted Stock immediately shall vest and any applicable  restrictions
shall  lapse.  The 1996  Incentive  Plan  defines  a change  of  control  as the
consummation  of a  tender  offer  for  25% or more  of our  outstanding  voting
securities,  our merger or consolidation into another  corporation less than 75%
of the  outstanding  voting  securities  of which are owned in  aggregate by our
stockholders  immediately  prior to the  merger  or  consolidation,  the sale of
substantially all of our assets other than to a wholly-owned subsidiary,  or the
acquisition  by  any  person,  business  or  entity  other  than  by  reason  of
inheritance  of over 25% of our  outstanding  voting  securities.  The change of
control  provisions  of the  1996  Incentive  Plan  may  operate  as a  material
disincentive or impediment to the  consummation  of any transaction  which could
result in a change of control.
    
         The  1996  Incentive  Plan  provides  the  Board  of  Directors  or the
Compensation  Committee discretion to grant SARs in connection with any grant of
options.  Upon the  exercise of a SAR, the holder shall be entitled to receive a
cash payment in an amount equal to the difference between the exercise price per
share of options  then  exercised by him and the fair market value of the Common
Stock as of the  exercise  date.  The holder is  required  to  exercise  options
covering the number of shares,  which are subject to the SAR so exercised.  SARs
are not exercisable during the first six months after the date of grant, and may
be transferred only by will or the laws of descent and distribution.

         The 1996  Incentive  Plan also  provides  the Board of Directors or the
Compensation  Committee  discretion to grant to key persons shares of Restricted
Stock  subject to certain  limitations  on  transfer  and  substantial  risks of
forfeiture.

1997 Stock Incentive Plan

   
         The Board of Directors adopted the 1997 Stock Incentive Plan (the "1997
Incentive  Plan") on April 10, 1997.  The 1997  Incentive  Plan provides for the
granting of  Incentive  Stock  Options  within the meaning of Section 422 of the
Internal  Revenue Code of 1986,  as amended  (the  "Code"),  nonqualified  stock
options,  SARs  and  grants  of  shares  of  Common  stock  subject  to  certain
restrictions  (collectively,  "Awards") up to a maximum of  1,650,000  shares to
officers,  directors,  key employees and others.  Incentive Stock Options can be
awarded only to employees at the time of the grant.  No ISO may be granted under
the 1997 Incentive Plan after April 9, 2007.

         The Compensation Committee administers the 1996 Incentive Plan (subject
to the  authority  of the  full  Board of  Directors).  The  Board of  Directors
determines  the  terms  and  conditions  of the  Awards  granted  under the 1997
Incentive Plan,  including the exercise  price,  number of shares subject to the
option and the exercisability thereof.

<PAGE>



         The exercise  price of all Incentive  Stock  Options  granted under the
1997  Incentive  Plan must  equal at least the fair  market  value of the Common
Stock  on the  date of  grant.  In the  case of  Substantial  Stockholders,  the
exercise  price of  Incentive  Stock  Options  must be at least 110% of the fair
market value of the Common Stock on the date of grant. The exercise price of all
nonqualified  stock  options  granted  under the 1997  Incentive  Plan  shall be
determined by the Compensation Committee. The term of any Incentive Stock Option
granted  under  the 1997  Incentive  Plan may not  exceed  ten  years,  or,  for
Incentive Stock Options  granted to Substantial  Stockholders,  five years.  The
1997 Incentive Plan may be amended or terminated by the Board of Directors,  but
no such action may impair the rights of a participant under a previously granted
option.

   
         The  1997  Incentive  Plan  provides  the  Compensation  Committee  the
discretion to determine when options granted thereunder shall become exercisable
and the vesting  period of such options.  Upon  termination  of a  participant's
employment  or  relationship,  options  may be  exercised  only  to  the  extent
exercisable  on the date of such  termination  (within  three  months),  but not
thereafter,  unless termination is due to death or disability, in which case the
options are exercisable within one year of termination.
    

         The 1997 Incentive Plan provides the Committee discretion to grant SARs
to key employees,  consultants  and directors.  Promptly after exercise of a SAR
the holder  shall be  entitled  to  receive  in chase,  by check or in shares of
Common  Stock,  an amount  equal to the excess of the fair  market  value on the
exercise  date of the  shares of Common  Stock as to which the SAR is  exercised
over the base price of such shares, which shall be determined by the Committee

   
         The 1996  Incentive  Plan  also  provides  the  Compensation  Committee
discretion to grant to key persons shares of restricted stock subject to certain
contingencies and restrictions as the Committee may determine.

         As of December  31, 1997 we had granted a total of  1,627,430  options.
Each of the outstanding options has an exercise price at least equal to the fair
market  value of the  Common  Stock on the date of grant with the  exception  of
80,000 shares which are subject to acquisition by one of our officers and 20,000
shares  which are subject to  acquisition  by one of our  employees at $0.0l per
share over the period 1995 through 1999. As of December 31, 1997, we had no SARs
outstanding  and we had made one grant of  Restricted  Stock of 10,000 shares of
Common Stock to a former officer.
    

Escrowed Shares

   
         As a condition to our initial public offering,  Royce Investment Group,
the Representative of the several underwriters (the "Representative"),  required
certain of our  stockholders  to deposit a total of  1,800,000  shares of Common
Stock in escrow pursuant to an escrow agreement with Continental  Stock Transfer
& Trust  Company,  the escrow  agent and the  Representative.  Of such  Escrowed
Shares,  1,707,210 shares are owned by our officers and directors.  The Escrowed
Shares are subject to incremental  release to the depositing  stockholders based
upon our total revenues and net earnings (loss) for the 12-month  periods ending
September 30, 1997,  1998 and 1999. The Escrowed  Shares will be released in the
amounts  set  forth  below  only  upon the  achievement  by the  Company  of the
following Performance Targets:
    

         o    The  Escrowed  Shares  will  be  released   incrementally  over  a
              three-year  period  only  in the  event  our  gross  revenues  and
              earnings  (loss)  per  share  for  the  12-month   periods  ending
              September  30, 1997,  1998 and 1999 equal or exceed the  following
              gross revenue and earnings (loss) per share targets:

         o    300,000   shares  if  we  achieve  gross   revenues  of  at  least
              $20,000,000  and a net loss, if any, not in excess of $500,000 for
              the 12 months ending September 30, 1997;

         o    750,000   shares  if  we  achieve  gross   revenues  of  at  least
              $45,000,000,  and  earnings per share of at least $1.00 for the 12
              months ending September 30, 1998; and


                                     - 46 -

<PAGE>
   


         o 

              750,000   shares  if  we  achieve  gross   revenues  of  at  least
              $90,000,000  and  earnings  per share of at least $1.25 for the 12
              months ending September 30, 1999.


         o    If such  per  share  targets  are  not met in any of the  relevant
              12-month  periods and the price of the Common  Stock does not meet
              or  exceed  agreed  upon  price  levels,  certain  amounts  of the
              Escrowed  Shares  will  be  returned  to us for  each  period  and
              canceled.

         o    All the Escrowed  Shares will be released to the  stockholders  if
              the  closing  price of the Common  Stock as reported on The Nasdaq
              SmallCap  Market  following this offering equals or exceeds $11.00
              for 25  consecutive  trading  days  or 30  out  of 35  consecutive
              trading days during the period ending September 30, 1999.

         The difference  between the initial offering price and the market value
(at the time of release) of any Escrowed Shares released will be deemed to be an
additional compensation expense. Such expense, depending on the price per share,
may have the effect of reducing or eliminating  any earnings per share and could
have a negative effect on the market price for our Common Stock.

         We did not meet the targets for escrow  release for  September 30, 1997
and September 30, 1998. As a result,  300,000 and 750,000 shares,  respectively,
were canceled from the escrow pool  resulting in a reduction of 2.1% and 3.6% of
our outstanding shares of Common Stock.

         The earnings per share  calculation  will be based on the fully diluted
earnings per share,  but excluding  shares issued  pursuant to the Unit Purchase
Option granted to the Representative,  extraordinary  items, or any compensation
expense  charged  related  to  the  release  of  the  Escrowed  Shares.  We,  in
consultation  with our independent  auditors,  weill make the  determination  of
earnings per share in accordance with generally accepted accounting  principles.
Our  determination  will be based on our financial  statements filed pursuant to
the  Securities  Exchange  Act of 1934,  as  amended.  Escrowed  Shares  are not
transferable or assignable although they may be voted by the holder.

         The Performance Targets and the Nasdaq Price Target were determined the
result of our negotiations with the  Representative  and do not imply or predict
our future performance.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         Please note that we did not secure an independent  determination of the
fairness and  reasonableness  of the  transactions  and  arrangements  described
below. In each instance the disinterested  directors (either at or following the
time of the transaction)  reviewed and approved the fairness and  reasonableness
of the terms of the  transaction.  We believe that each transaction was fair and
reasonable  to us and on terms at least as favorable as could have been obtained
from  non-affiliates.  Transactions between any corporation and its officers and
directors are subject to inherent conflicts of interest.

Tech International and Tech Virginia

         Since December 1992, we have maintained various business  relationships
with Tech  International and since 1994, with Tech Virginia.  Tech International
operates a computer software and consulting  business.  Until December 30, 1994,
Tech  International's  Virginia  operations were conducted  through its Virginia
business unit. In December 30, 1994,  Tech  International  spun-off the Virginia
business unit (the  "Spin-Off") as Tech Virginia.  Edward G. Newman, a principal
stockholder,  director and our Chairman,  President and Chief Executive  Officer
and Steven A. Newman and Eugene J. Amobi, directors, were the stockholders,  and
continue as officers and directors of Tech Virginia. Eugene J. Amobi is the sole
director and stockholder of Tech International.

Management Personnel Agreements with Tech Virginia

         Messrs.  Edward G.  Newman,  Steven A. Newman and Eugene Amobi each had
employment  agreements  with Tech Virginia under which each of them was entitled
to a salary and was eligible to receive  certain  bonuses.  The agreements  with
Messrs.  Edward G. Newman and Steven A. Newman  required  each of them to devote
only reasonable time and attention to Tech Virginia,  provided their  activities
for Tech Virginia did not interfere with their obligations to our company.  Upon
our acquisition of Tech Virginia,  such employment agreements were terminated by
agreement with Messrs.  Newman,  Newman, and Amobi. Messrs.  Newman,  Newman and
Amobi have continued to provide  services to Tech Virginia since the acquisition
without  contract but under  similar terms and  conditions  as their  terminated
agreements.

         During fiscal 1997, we accrued, but did not pay, approximately $97,800,
respectively,  in salaries and automobile  allowances payable to Eugene Amobi, a
director,  for services provided to Tech Virginia.  As of December 31, 1997, the
total  amount  accrued  and owed for such items to Mr.  Amobi was  approximately
$215,000,  which was reduced by $25,000  paid to an entity  affiliated  with Mr.
Amobi after December 31, 1997.

Consulting Agreement

         We have a consulting  agreement  with Steven A. Newman.  See "Executive
Compensation - Consulting Agreements."

Legal Services

         James J.  Ralabate,  Esq.  was paid  $68,031  and  $275,548 in fees and
disbursements for legal services rendered to us during fiscal 1996 and
         fiscal 1997, respectively.

         Parker  Chapin  Flattau & Klimpl,  LLP,  the law firm where Martin Eric
Weisberg,  Esq.  is a  partner,  was paid  $5,179  and  $137,346.15  in fees and
disbursements  for legal  services  rendered to us during fiscal 1996 and fiscal
1997, respectively.

                         SHARES ELIGIBLE FOR FUTURE SALE

         Sales of a  substantial  number of shares  of our  Common  Stock in the
public market following this offering could adversely affect the market price of
the  Common  Stock.  Of the  23,621,583  shares  of  Common  Stock  that will be
outstanding  or  registered  for sale  upon  the  completion  of this  offering,
22,391,426 will be freely tradeable without restriction or further  registration
under the Securities Act. This includes:

         o     19,250,246   shares of  Common   Stock   which   are   issued and
               outstanding;
         o     141,700 unissued shares of Common Stock registered in  connection
               with the Series C Preferred Stock,
         o     899,480 unissued shares of Common Stock registered in  connection
               with  the April 1998 Equity Line of Credit Private Placement; and
         o     the 2,100,000  unissued   shares   of  Common Stock registered in
               connection with the Financing Arrangement.

         The remaining  1,014,140  shares include 750,000 shares of Common Stock
which are "Escrowed  Shares" (see "Executive  Compensation -- Escrowed  Shares")
and are subject to incremental  release over a one-year  period if certain share
targets  are met,  and  480,157  shares  of the  Common  Stock  are  "restricted
securities" as that term is defined in Rule 144 promulgated under the Securities
Act. The  restricted  shares may be sold  pursuant to an effective  registration
statement under the Securities Act, in compliance with the exemption  provisions
of Rule 144 or pursuant to another  exemption  under the Securities  Act. In the
absence of any  agreement to the contrary,  the  outstanding  restricted  Common
Stock could be sold in accordance  with one or more other  exemptions  under the
Securities  Act  (including  Rule 144).  Rule 144, as amended,  permits sales of
restricted  securities  by any person  (whether or not an  affiliate)  after one
year, at which time sales can be made subject to the Rule's  existing volume and
other limitations and by non-affiliates  without adhering to Rule 144's existing
volume or other limitations after two years. Future sales of substantial amounts
of shares in the public market,  or the perception  that such sales could occur,
could  adversely  affect the price of the shares in any market  that may develop
for the trading of such shares.

                            DESCRIPTION OF SECURITIES

General

         Our authorized  capital stock  consists of 40,000,000  shares of Common
Stock,  par value $.01 per share,  and 6,000,000  shares of Preferred Stock, par
value $.01 per share.  As of the date  hereof,  there are  20,752,729  shares of
Common Stock and 281 shares of Series C Preferred Stock issued and  outstanding.
We have  reserved  6,827,952  shares of Common  Stock for  issuance  pursuant to
outstanding options and warrants.

Common Stock

         The holders of our Common Stock are entitled to one vote for each share
held  of  record  on all  matters  submitted  to a  vote  of  stockholders.  Our
Certificate of  Incorporation  and By-Laws do not provide for cumulative  voting
rights in the election of directors.  Accordingly,  holders of a majority of the
shares of Common Stock  entitled to vote in any election of directors  may elect
all of the directors standing for election. Holders of Common Stock are entitled
to receive  ratably such  dividends as may be declared by the Board of Directors
out of funds  legally  available  therefor.  In the  event  of our  liquidation,
dissolution or winding up, holders of Common Stock are entitled to share ratably
in the assets  remaining after payment of  liabilities.  Holders of Common Stock
have no  preemptive,  conversion or redemption  rights.  All of the  outstanding
shares of Common Stock are fully-paid and nonassessable.

Preferred Stock

         The Board of Directors has the authority,  without further  stockholder
approval,  to issue up to 6,000,000  shares of Preferred Stock from time to time
in one or more series,  to establish the number of shares to be included in each
such series, and to fix the designations,  powers, preferences and rights of the
shares of each such series and the  qualifications,  limitations or restrictions
thereof.  The  issuance  of  Preferred  Stock may have the effect of delaying or
preventing a change in control.  The issuance of Preferred  Stock could decrease
the amount of earnings and assets  available for  distribution to the holders of
Common Stock, if any, or could adversely affect the rights and powers, including
voting  rights,  of the holders of the Common Stock.  In certain  circumstances,
such  issuances  could have the  effect of  decreasing  the market  price of the
Common Stock.

         Series C Preferred Stock

         On May 15, 1998,  the Board of Directors  authorized  the issuance of a
series of  Preferred  Stock  consisting  of 375 shares (the  "Series C Preferred
Stock"),  each such  share of  Series C  Preferred  Stock has a stated  value of
$1,000 (the "Liquidation Preference"),  pursuant to a Certificate of Designation
(the "Certificate of Designation").

         Dividends.  The holders of the shares of Series C  Preferred  Stock are
entitled to receive,  when and as declared by the Board of Directors,  dividends
at the rate of five percent of the stated  Liquidation  Preference per share per
annum,  and no more,  payable,  at the discretion of the Board of Directors,  in
Common Stock or cash. Dividends accrue on each share of Series C Preferred Stock
from the date of initial  issuance.  Such  dividends  are in  preference  to any
distributions on any outstanding  shares of our Common Stock or any other of our
equity  securities  that are junior to the Preferred  Stock as to the payment of
dividends.

         Conversion  Rights.  The holders of Series C Preferred Stock shall have
conversion  rights as follows:  (i) no shares of Series C Preferred Stock may be
converted  prior to August  15,  1998;  (ii) at any time after  August 15,  1998
through  November 14, 1998,  up to  twenty-five  (25%)  percent of the shares of
Series C Preferred Stock then outstanding may be converted, at the option of the
holders thereof;  and (iii) thereafter,  on November 15, 1998, February 15, 1999
and May 15,  1999,  an  additional  twenty-five  (25%)  percent of the shares of
Series C Preferred Stock then outstanding may be converted,  on a cumulative and
pro rata basis,  at the option of the holders  thereof.  The number of shares of
fully-paid and nonassessable Common Stock into which each share of
    
                                     - 52 -

<PAGE>
   


Series C Preferred  Stock may be converted  shall be  determined by dividing the
Liquidation Preference by an amount (the "Conversion Price") equal to the lesser
of (A) 100% of the average  closing bid price of the Common Stock as reported on
the Nasdaq SmallCap  Market or any successor  exchange in which the Common Stock
is listed for the five  trading days  preceding  the date on which the holder of
the Series C Preferred  Stock has  telecopied a notice of  conversion to us (the
"Conversion Date") and (B) $4.00.

         On May 15,  2000,  the holders of the Series C Preferred  Stock will be
required to convert all of their outstanding  shares of Series C Preferred Stock
into  shares of Common  Stock.  Until  converted,  we will be entitled to redeem
shares  of  Series C  Preferred  Stock in  accordance  with the  Certificate  of
Designation,  regardless  of whether or not we  received a notice of  conversion
with respect to such shares.

         We will at all times  when any shares of Series C  Preferred  Stock are
outstanding,  reserve and keep  available  out of our  authorized  but  unissued
stock,  such  number of shares of Common  Stock as,  from time to time,  will be
sufficient  to  effect  the  conversion  of all  outstanding  shares of Series C
Preferred Stock.

         Redemption. At any time after May 15, 1998, we may redeem up to 100% of
the  outstanding  shares  of the  Series C  Preferred  Stock  at the  applicable
redemption  price,  provided,  that (x) we have received a notice of conversion,
and (y) the  Conversion  Price is below $3.40.  We will give  written  notice by
telecopy, to the holders of Series C Preferred Stock to be redeemed at least one
business  day  after  receipt  of the  notice  of  conversion  prior to the date
specified for redemption  (the  "Redemption  Date").  Such notice will state the
Redemption  Date, the Redemption Price (as hereinafter  defined),  the number of
shares of Series C Preferred Stock of such holders to be redeemed and shall call
upon  such  holders  to  surrender  to us on the  Redemption  Date at the  place
designated in the notice such holders' redeemed stock.

         We have the option to redeem  all or a portion  of all the  outstanding
shares of Series C Preferred  Sock at a cash price equal to $3.40  multiplied by
the number of shares the Series C Preferred Stock would convert into on the date
of redemption.

         Voting Rights.  Except as otherwise required by law, the holders of the
Series C Preferred Stock are not be entitled to vote upon any matter relating to
our business or affairs or for any other purpose.

         Status.  In case any  outstanding  shares of Series C  Preferred  Stock
shall be  redeemed,  the shares so  redeemed  shall be deemed to be  permanently
canceled and shall not resume the status of  authorized  but unissued  shares of
Series C Preferred Stock.

         Other Designations of Preferred Stock

         As of the date of this Prospectus, we have not designated any shares of
Preferred  Stock  other than the Series A  Preferred  Stock,  Series B Preferred
Stock and Series C Preferred Stock. There are no other shares of Preferred Stock
outstanding, and we have no plans to issue any other shares of Preferred Stock.

                    DELAWARE BUSINESS COMBINATION PROVISIONS

         As a Delaware  corporation,  we are  subject to Section  203  ("Section
203") of the Delaware  General  Corporation  Law (the "DGCL"),  which  regulates
large  accumulations of shares,  including those made by tender offers.  Section
203 may have the  effect of  significantly  delaying  a  purchaser's  ability to
acquire our  organization  if such  acquisition  is not approved by the Board of
Directors.

         In general,  Section 203 prevents an "Interested  Stockholder" (defined
generally  as a person with 15% or more of a  corporation's  outstanding  voting
stock) from engaging in a "Business Combination" (defined below) with a Delaware
corporation  for three years following the date such person became an Interested
Stockholder.  For purposes of Section 203, the term  "Business  Combination"  is
defined broadly to include mergers and certain other transactions with or caused
by the Interested  Stockholder,  sales or other  dispositions  to the Interested
Stockholder (except  proportionately  with the corporation's other stockholders)
of  assets  of the  corporation  or a  subsidiary  equal  to 10% or  more of the
aggregate  market  value  of  the  corporation's   consolidated  assets  or  our
outstanding  stock;  the issuance or transfer by the corporation or a subsidiary
of stock of the  corporation or such  subsidiary to the  Interested  Stockholder
(except for transfers in a conversion or exchange or a pro-rata  distribution or
certain other transactions,  none of which increase the Interested Stockholder's
proportionate  ownership  of any class or series  of the  corporation's  or such
subsidiary's   stock);  or  receipt  by  the  Interested   Stockholder   (except
proportionately  as a  stockholder),  directly  or  indirectly,  of  any  loans,
advances, guarantees, pledges or other financial benefits provided by or through
the corporation or a subsidiary.

         The three-year  moratorium imposed on Business  Combinations by Section
203 does not apply if:

         (a)  prior to the date on which a  stockholder  becomes  an  Interested
              Stockholder,  the Board of Directors  approves either the Business
              Combination  or  the  transaction  that  resulted  in  the  person
              becoming an Interested Stockholder,

         (b)  the Interested  Stockholder owns 85% of the  corporation's  voting
              stock upon consummation of the transaction that made him or her an
              Interested  Stockholder (excluding from the 85% calculation shares
              owned by directors  who are also officers of the  corporation  and
              shares held by employee stock plans which do not permit  employees
              to decide  confidentially  whether to accept a tender or  exchange
              offer); or

         (c)  on or after the date a person  becomes an Interested  Stockholder,
              the Board of Directors approves the Business  Combination,  and it
              is also  approved at a  stockholder  meeting by  two-thirds of the
              voting stock not owned by the Interested Stockholder.

         Under Section 203, the  restrictions  described  above do not apply if,
among other things,  the  corporation's  original  certificate of  incorporation
contains a provision electing not to be governed by Section 203. Our Certificate
of Incorporation does not contain such a provision.  The restrictions  described
above  also  do not  apply  to  certain  Business  Combinations  proposed  by an
Interested  Stockholder  following the  announcement  or  notification of one of
certain  extraordinary  transactions  involving the corporation and a person who
had not been an Interested  Stockholder  during the previous  three years or who
became  an  Interested  Stockholder  with  the  approval  of a  majority  of the
corporation's directors.

                              PLAN OF DISTRIBUTION

         We will issue the shares of Common Stock we are registering directly to
the  Investor in  connection  with the  Financing  Arrangement.  See  "Financing
Arrangement."

         The  subsequent  distribution  of such  Shares by the  Investor  may be
effected from time to time in one or more of the following transactions:

         o on any U.S.  securities  exchange  on which our  Common  Stock may be
           listed at the time of such sale; 
         o in the over-the-counter market;
         o in  transactions  other  than  on  such exchanges or in the over-the-
           counter market; 
         o in connection with short sales; 
         o in a combination of any of the above transactions.


         The  Investor  may may offer its shares of Common  Stock at  prevailing
market prices at the time of sale, at prices related to such  prevailing  market
prices, at negotiated prices or at fixed prices.

         The Investor may use broker-dealers to sell its shares of Common Stock.
If this happens, broker-dealers will either receive discounts or commission from
the  Investor,  or they will receive  commissions  from  purchasers of shares of
Common  Stock for whom they acted as agents.  Such brokers may act as dealers by
purchasing any and all of the Shares covered by this Prospectus either as agents
for others or as principals for their own accounts and reselling such securities
pursuant to this Prospectus.

         The  Investor and any  broker-dealers  or other  persons  acting on the
behalf of parties  that  participate  in the  distribution  of the Shares may be
deemed to be  underwriters.  As such, any commissions or profits they receive on
the  resale  of the  Shares  may be  deemed  to be  underwriting  discounts  and
commissions under the Securities Act.

         As of the date of this  Prospectus,  we are not aware of any agreement,
arrangement or understanding  between any broker or dealer and the Investor with
respect to the offer or sale of the Shares pursuant to this Prospectus.

         To the  extent  required  under  the  Securities  Act,  we will  file a
supplemental prospectus to disclose (a) the name of any such broker-dealers, (b)
the  number of Shares  involved,  (c) the price at which  such  Shares are to be
sold,  (d) the  commissions  paid or  discounts or  concessions  allowed to such
broker-dealers,  where applicable,  (e) that such broker-dealers did not conduct
any  investigation  to verify the  information  set out in this  Prospectus,  as
supplemented, and (f) other facts material to the transaction.

         We will receive proceeds from the draw downs, the Call Options, if any,
and the exercise of the Warrants issued pursuant to the Financing Agreement.  We
will use such proceeds for general corporate purposes.

         The Subscription Agreement for the Financing Arrangement has reciprocal
indemnification  provisions against certain liabilities,  including  liabilities
under the  Securities  Act,  which may be based upon,  among other  things,  any
untrue  statement or alleged untrue statement of a material fact or any omission
or  alleged  omission  of a  material  fact.  We have  agreed to bear  customary
expenses  incident  to the  registration  of the Shares  for the  benefit of the
Investor in accordance with such agreements,  other than underwriting  discounts
and  commissions  directly  attributable to the sale of such securities by or on
behalf of the Investor.

         We have  agreed  to keep the  Registration  Statement  relating  to the
offering  and sale of the Common Stock to the  Investor  continuously  effective
until the earlier of sale of all the Shares or 12 months.

                 INDEMNIFICATION FOR SECURITIES ACT LIABILITIES

         Section  145 of the  DGCL  provides,  in  general,  that a  corporation
incorporated under the laws of the State of Delaware,  such as our company,  may
indemnify  any person who was or is a party or is  threatened to be made a party
to any threatened, pending or completed action, suit or proceeding (other than a
derivative  action by or in the right of the  corporation) by reason of the fact
that  such  person  is or was a  director,  officer,  employee  or  agent of the
corporation,  or is or was  serving  at the  request  of  the  corporation  as a
director,  officer,  employee or agent of another  enterprise,  against expenses
(including  attorneys'  fees),  judgments,  fines and amounts paid in settlement
actually and reasonably  incurred by such person in connection with such action,
suit or  proceeding  if such  person  acted in good  faith and in a manner  such
person reasonably  believed to be in or not opposed to the best interests of the
corporation,  and,  with respect to any criminal  action or  proceeding,  had no
reasonable cause to believe such person's conduct was unlawful. In the case of a
derivative action, a Delaware  corporation may indemnify any such person against
expenses  (including  attorneys' fees) actually and reasonably  incurred by such
person in  connection  with the defense or  settlement of such action or suit if
such person acted in good faith and in a manner such person reasonably  believed
to be in or not opposed to the best interests of the corporation, except that no
indemnification  shall be made in respect  of any  claim,  issue or matter as to
which such  person  shall  have been  adjudged  to be liable to the  corporation
unless  and only to the  extent  that  the  Court of  Chancery  of the  State of
Delaware or any other court in which such  action was  brought  determines  such
person is fairly and reasonably entitled to indemnity for such expenses.

         Our Certificate of  Incorporation  provides that directors shall not be
personally  liable for monetary  damages to us or our stockholders for breach of
fiduciary  duty as a director,  except for liability  resulting from a breach of
the director's duty of loyalty to our  stockholders,  intentional  misconduct or
wilful  violation of law,  actions or inactions  not in good faith,  an unlawful
stock purchase or payment of a dividend under Delaware law, or transactions from
which the  director  derives  improper  personal  benefit.  Such  limitation  of
liability  does not  affect  the  availability  of  equitable  remedies  such as
injunctive  relief  or  rescission.   Our  Certificate  of  Incorporation   also
authorizes us to indemnify our officers,  directors and other agents, by bylaws,
agreements or otherwise,  to the fullest extent permitted under Delaware law. We
have entered into an Indemnification Agreement (the "Indemnification Agreement")
with each of our  directors  and officers  which may, in some cases,  be broader
than the specific  indemnification  provisions  contained in our  Certificate of
Incorporation or as otherwise permitted under Delaware law. Each Indemnification
Agreement  may require us, among other  things,  to indemnify  such officers and
directors  against certain  liabilities that may arise by reason of their status
or service as a director or officer,  against  liabilities  arising from willful
misconduct  of a  culpable  nature,  and  to  obtain  directors'  and  officers'
liability insurance if available on reasonable terms.

         We maintain a directors  and  officers  liability  policy with  Genesis
Insurance  Company that contains a limit of liability of  $3,000,000  per policy
year.

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

                                  LEGAL MATTERS

         Parker Chapin Flattau & Klimpl,  LLP, New York, New York will pass upon
the validity of the securities  offered  hereby.  Martin Eric Weisberg,  Esq., a
member of the firm, is our Secretary and one of our Directors.

                        REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors
of Xybernaut Corporation and Subsidiary

   We have audited the  accompanying  consolidated  balance  sheets of Xybernaut
Corporation  and Subsidiary  (the Company) as of December 31, 1997 and 1996, and
the related  consolidated  statements of operations,  stockholders'  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 the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

   In our opinion, the financial statements referred to above present fairly, in
all  material  respects,   the  consolidated  financial  position  of  Xybernaut
Corporation   and  Subsidiary  as  of  December  31,  1997  and  1996,  and  the
consolidated results of their operations and their cash flows for the years then
ended, in conformity with generally accepted accounting principles.

   The accompanying  financial  statements have been prepared  assuming that the
Company will continue as a going concern.  The Company experienced a net loss of
$9,479,966  in 1997 and as discussed in Note 1 to the financial  statements,  is
currently  negotiating a commitment for an equity placement and a standby equity
line. The Company's  ability to draw upon this line of credit is contingent upon
their ability to file and have the  Securities and Exchange  Commission  declare
effective  a  registration  statement  for  these  securities.  In the event the
Company can draw upon this standby  equity line of credit,  continuation  of the
business  thereafter  is  dependent  on  the  Company's  ability  to  achieve  a
sufficient  cash  flow  to meet  its  cash  requirements.  These  matters  raise
substantial  doubt about the Company's  ability to continue as a going  concern.
Management's  plan in regard to these  matters is also  described in Note 1. The
financial  statements do not include any adjustments  that might result from the
outcome of this uncertainty.

                              XYBERNAUT CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.       Business and Financing:

The Company:

         Xybernaut  Corporation  (the "Company") was originally  incorporated in
Virginia in October 1990 as Contemporary  Products & Services,  Inc. and changed
its name to Computer Products & Services,  Inc. ("CPSI") in 1992. In April 1996,
the Company was merged with Xybernaut Corporation to change the Company name and
reincorporate  in Delaware.  Since the  commencement  of  operations in November
1992, the Company has engaged in the research, development and commercialization
of products  intended to bridge the widening gap between  people and  knowledge.
The  first  product  to be  commercialized  by the  Company  is the  proprietary
portable computer technology and related software  applications  embodied in its
Mobile  Assistant(R)  product.  Additional  software  products  are  planned for
development and use on the Mobile Assistant(R) and other personal computers.

         On July 18, 1996, the Company successfully completed the Initial Public
Offering ("IPO") of its Common Stock and warrants (NASDAQ symbol XYBR and XYBRW)
which are traded on the NASDAQ SmallCap Market.

         The Company was a development stage enterprise  through March 31, 1995.
Subsequently,  the Company has commenced principal operations and,  accordingly,
these  financial  statements  are not presented in compliance  with Statement of
Financial  Accounting Standard No. 7 which describes the financial  presentation
for development stage enterprises.


Financing:

         The Company has  received a  commitment  for an equity  placement of $1
million  and a standby  equity  line of $10  million  and is in the  process  of
finalizing these  arrangements.  The Company's ability to draw upon this line of
credit  is  contingent  upon its  ability  to file and have the  Securities  and
Exchange  Commission  declare  effective  a  registration  statement  for  these
securities.  In the event the Company can draw upon this standby  equity line of
credit,  continuation  of the business  thereafter is dependent on the Company's
ability to achieve a sufficient  cash flow to meet its cash  requirements.  This
commitment  expires  on April  14,  1998.  It is the  opinion  of the  Company's
management that such funding  arrangements are readily  available to the Company
and the  execution of any such  arrangements  is a decision  that will depend on
timing,   market   conditions  and  the  final  terms  and  conditions  of  such
arrangements.  Production  of the MA IV  model  of the  Mobile  Assistant(R)  is
expected to begin in the quarter ending December 31, 1998, and receivables  from
sales of the Mobile Assistant(R) are expected to provide significant  collateral
for borrowing facilities at that point.  Although there can be no assurance that
such  facilities  will be  available,  the Company  intends to seek to establish
secured borrowing facilities as soon as appropriate collateral is available. The
Company's  management  believes that the combination of cash on hand,  operating
cash flows, and additional outside funding will provide sufficient  liquidity to
meet the Company's cash requirements until at least March 1999.


2.       Summary of Significant Accounting Policies

Principles of Consolidation:

          The  consolidated  financial  statements  include the  accounts of the
Company and its wholly owned  subsidiary,  Tech  International  of Virginia Inc.
("TechVirginia"). In connection with the IPO, the Company

                                      F- 7

<PAGE>



exercised  its  option to acquire  all of the  capital  stock of Tech  Virginia.
Financial  statements  prior to the exercise of the option  reflect the combined
financial position and results of operations of the Company and Tech Virginia.
All significant intercompany accounts and transactions have been eliminated.

Use of Estimates in the Preparation of Financial Statements:

         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.


Cash and Cash Equivalents:

         The Company considers all highly liquid  investments  purchased with an
original maturity of three months or less to be cash equivalents.

Inventories:

         Inventories, consisting principally of component parts held for resale,
are stated at the lower of cost or market, with cost determined by the first-in,
first-out  method.  As of December  31, 1997 and 1996,  the  allowance to reduce
inventory   balances  to  net  realizable   value  was  $724,978  and  $202,440,
respectively.  Most of the reserves and write downs in inventory  values  result
from the introduction of new products and technology resulting in a reduction or
loss of value of older  products  or  technology.  The sales  prices of the 133P
model of the Mobile  Assistant(R) will be monitored in light of the introduction
of the MA IV model and reserves will be taken as appropriate if the value of the
133P inventory is determined to have been impaired. At this point, the Company's
management  does  not  believe  that  the  value  of the  133P  model  has  been
significantly impaired by the introduction of the MA IV.

Property, Equipment, Furniture and Fixtures:

         Property, equipment,  furniture and fixtures are stated at cost and are
depreciated  on a  straight-line  basis over the  estimated  useful lives of the
assets, as follows:


Equipment.............................          3-5 years
Furniture and fixtures................            5 years
Demonstrator units....................            2 years
Leasehold improvements................            3 years

         Expenditures  for maintenance  and repairs are charged  directly to the
appropriate operating account at the time the expense is incurred.  Expenditures
determined to represent additions and betterments are capitalized.

Software Development Costs:

         The Company's policy is to capitalize  software  development costs when
technological  feasibility  has been  established,  based on a detailed  program
design  that is  complete,  has  been  confirmed  and  for  which  no  high-risk
development issues remain.

                                      F- 8

<PAGE>



         The   establishment  of  technological   feasibility  and  the  ongoing
assessment of the recovery of capitalized  software costs requires  considerable
judgment by management with respect to certain external factors  including,  but
not limited to,  technological  feasibility,  anticipated future gross revenues,
estimated  economic  life and changes in  software  and  hardware  technologies.
Capitalization  of software  costs will cease when the software is available for
general  release to customers,  at which time  amortization of the costs begins.
These costs will be amortized using the greater of the amount computed using the
straight-line  method over the remaining  estimated economic life of the product
or the ratio of current gross  revenues from the product to the total of current
and  anticipated  future gross  revenues from the product.  Since the Company is
currently in the planning and development phase for software toolkits,  no costs
have been capitalized to date.

Intangible Assets:

         Patent costs consist of legal fees,  filing fees and other direct costs
incurred  in  obtaining  and   maintaining   patents  and  are  amortized  on  a
straight-line basis over a five-year period.

Tooling Costs:

         Tooling costs consist of reimbursed expenses to third-party vendors for
molds to be used exclusively in the  manufacturing of the Company's  proprietary
head-mounted  display  ("HMD") and the computing  unit for the Mobile  Assistant
(R).  Capitalized  tooling costs will be transferred  to inventory  based on the
estimated  total  number of HMDs and  computing  units to be  produced  from the
molds. No costs have been transferred to inventory as of December 31, 1997.

Impairment of Long-Lived Assets:

         Management  of the Company  monitors the carrying  value of  long-lived
assets for potential impairment on an on-going basis. Potential impairment would
be  determined  by  comparing  the  carrying  value of these  assets  with their
related, expected future net cash flows. Should the sum of the related, expected
future  net  cash  flows be less  than  the  carrying  value,  management  would
determine  whether an impairment  loss should be recognized.  An impairment loss
would be measured by the amount by which the carrying value of the asset exceeds
the future discounted cash flows.

Revenue Recognition and Warranties:

         Product  sales are  recorded on shipment  pursuant to a valid  customer
purchase  order.  For  equipment  shipped  under  equipment  rental  or  leasing
agreements,  revenue is recognized on a straight-line basis over the term of the
rental or lease agreement.  Consulting revenue is recognized as the services are
performed pursuant to a written agreement with the client. The Company generally
provides a one-year warranty on parts. The Company's suppliers for the computing
unit and the HMD provide the Company  with  similar  warranties  and as a result
warranty reserves are immaterial.

Research and Development Programs:

         Research and  development  costs are charged to operations as incurred,
including the cost of components  purchased for testing and product  development
that are salable but are intended for development work only.

Income Taxes:

         Deferred income tax assets and  liabilities  are computed  annually for
differences  between the financial  statement and income tax bases of assets and
liabilities  that will  result in taxable or  deductible  amounts in the future.
Such deferred income tax asset and liability  computations  are based on enacted
tax laws and rates  applicable to periods in which the  differences are expected
to affect taxable income. Income tax expense is the

                                      F- 9

<PAGE>



tax payable or  refundable  for the period  plus or minus the change  during the
period in deferred income tax assets and liabilities.

Net Loss Per Share:

         Effective  December  31,  1997,  the  Company  adopted  SFAS  No.  128,
"Earnings  Per Share," which  requires the  presentation  of basic  earnings per
share and diluted earnings per share.  Basic earnings per share are based on the
weighted average number of outstanding shares of Common Stock.  Diluted earnings
per share  adjusts the weighted  average for the  potential  dilution that could
occur if stock options,  warrants or other convertible securities were exercised
or  converted  into  Common  Stock.  For all  periods  presented  herein and for
historical  quarterly earnings per share amounts,  diluted earnings per share is
the same as basic earnings per share for the Company because the effects of such
items were anti-dilutive given the losses incurred in such periods.
Earnings per share for all periods presented conform to SFAS No. 128.

Escrowed Shares:

         Escrowed  shares,  if any, are considered  issued and  outstanding  and
reported as such on the balance  sheet.  For purposes of computing  the net loss
per common and common  equivalent  share,  they are not  considered  outstanding
until the conditions for their release are met.

Fair Value of Financial Instruments:

         The carrying amounts of financial  instruments  including cash and cash
equivalents, accounts receivable and accounts payable approximated fair value as
of December 31, 1997 and 1996, because of the relatively short maturity of these
instruments. The carrying value of the notes and loans payable approximated fair
value as of December 31, 1997 and 1996, based upon market prices for the same or
similar debt issues.

Recent Accounting Pronouncements:

         The Financial  Accounting  Standards Board has issued two new standards
which become effective for reporting  periods beginning after December 15, 1997.
SFAS No. 130, "Reporting  Comprehensive Income," requires additional disclosures
with respect to certain changes in assets and  liabilities  that previously were
not required to be reported as results of operations for the period. The Company
will begin  making the  additional  disclosures  required by SFAS No. 130 in the
first  quarter  of  1998.  SFAS  No.  131,  "Disclosures  about  Segments  of an
Enterprise  and  Related   Information,"   requires  financial  and  descriptive
information  with respect to "operating  segments" of an entity based on the way
management desegregates the entity for making internal operating decisions.  The
Company  will  begin  making  the  disclosures  required  by SFAS  No.  131 with
financial statements for the period ending December 31, 1998.

Interim results (unaudited):

         The  accompanying  consolidated  balance  sheet at June 30,  1998,  the
consolidated  statements of  operations  and cash flows for the six months ended
June 30, 1998 and 1997 and the consolidated  statement of  stockholders'  equity
for the six  months  ended  June  30,  1998 are  unaudited.  In the  opinion  of
management, these statements have been prepared on the same basis as the audited
consolidated  financial  statements and include all  adjustments,  consisting of
only normal  recurring  adjustments  necessary for the fair  presentation of the
results for the interm periods.  The data disclosed in the Notes to Consolidated
Financial Statements for these periods are unaudited.  The results of operations
for such periods are not necessarily  indicative of the results expected for the
full fiscal year or for any future period.

         Depreciation expense for the years ended December 31, 1997 and 1996 was
$186,761 and $80,231, respectively.

4.       Debt:

         Effective  November 17, 1995,  the Company  sold  $1,505,000  principal
amount of 7% Convertible Debentures due in 1997 (the "November 1995 Debentures")
and  paid a  placement  fee of 10% to the  placement  agent  in the  form  of an
interest-bearing  promissory note due at the time of the IPO. On April 16, 1996,
the Company sold $1,000,000 principal amount of 7% Convertible Debentures due in
1997  (the  "April  1996  Debentures")  and paid a  placement  fee of 12% to the
placement  agent in the form of an  interest-bearing  promissory note due at the
time of the IPO.

         Under  the  terms of these  debentures,  the  Company  had the right to
redeem all  debentures,  at a price  equal to 105% of  principal,  plus  accrued
interest,  if the IPO had not occurred  within one year after the closing  date.
The November 1995  Debentures and the April 1996 Debentures were to convert into
Units  upon a  successful  IPO by the  Company  at the rate of one Unit for each
$1.75 in principal.  The November 1995  Debentures and the April 1996 Debentures
were  converted  into  1,431,427  Units on July 18,  1996,  concurrent  with the
Company's IPO.

5.       Stockholders' Equity:

Initial Public Offering

         On July 18,  1996,  the Company  completed  its IPO and sold  2,415,000
Units at a price of $5.50 per Unit.  Each Unit  consisted of one share of Common
Stock and one  warrant to  purchase a share of Common  Stock at $9.00  ("Unit").
Gross  proceeds  from the sale of the Units were  $13,282,500  and net  proceeds
after expenses were $10,842,487.

         At the completion of the offering,  the underwriter  received an option
to purchase  210,000 Units at a price equal to 165% of the unit  offering  price
per unit during a period of four years commencing one year from July 18, 1996.

         In connection with this offering,  the Company's officers and directors
and certain  stockholders  deposited an aggregate of 1,800,000  shares of Common
Stock of the Company in an escrow account ("Escrowed Shares").  The Common Stock
in the escrow account is subject to release to such  stockholders  in increments
over a three year  period only in the event the  Company's  gross  revenues  and
earnings  (loss) per share for the twelve month  periods  ending  September  30,
1997,  1998  and  1999  meet  or  exceed  certain  performance  targets.  If the
performance  targets  are  not met in any of the  twelve  month  periods  ending
September 30, 1997,  1998, or 1999, the Escrowed  Shares will be returned to the
Company. In addition to the foregoing, all Escrowed Shares will be

                                      F- 11

<PAGE>



released to the  stockholders if certain stock price targets are met. The market
value of any Escrowed  Shares held by officers,  employees or consultants at the
time they are released will be deemed to be additional  compensation  expense to
the Company.  The parameters for the September 30, 1997 release were not met and
300,000 shares were canceled from the Escrowed Shares.

Common Stock (unaudited)

          In April  1998,  the  Company  entered  into an equity  line of credit
agreement in which the Company received an initial gross amount of $1,000,000 in
exchange  for  840,124  shares of Common  Stock.  Under  this line of equity the
Company has the right,  but not the  obligation,  to obtain up to an  additional
$10,000,000  in a series  of equity  draw  downs  based on terms and  conditions
specified in the line of equity.  In  connection  with this line of equity,  the
Company  issued  warrants to purchase up to 40,000  shares of stock at $1.76 and
20,000  shares of stock at $2.81 at any time  starting six months after  closing
and ending five years after closing.  The placement  agent for this  transaction
received a cash fee of 5% and 50,000 shares of unregistered stock.

         In May 1998,  the Company  completed a $375,000  private  placement  in
which the Company issued 110,294 shares of Common Stock

         In June 1998, the Company  completed a $1,000,000  private placement in
which the Company issued 153,846 unregistered shares of Common Stock.

         In June 1998,  the Company  amended  and  exercised a put option in the
aggregate  principal  amount  of  $3,000,000  under the  private  line of equity
agreement  mentioned  above. In connection with such action,  the Company issued
545,454 shares of Common Stock.

Preferred Stock (unaudited)

         In January 1998,  the Company placed 1,000 shares of Series B Preferred
Stock and received cash proceeds of  approximately  $974,000 from this issuance.
In connection  with this placement and the placement of 3,000 shares of Series B
Preferred  Stock in November 1997, the placement agent received 50,000 shares of
Common  Stock in lieu of 60 shares of Series B  Preferred,  warrants to purchase
25,000 shares of Common Stock at $2.1313 and warrants to purchase  75,000 shares
of Common  Stock at $3.025.  During the six months  ended June 30,  1998,  2,250
shares of Series A Preferred  Stock and 4,180 shares of Series B Preferred Stock
were converted to 4,878,074 shares of Common Stock, pursuant to their respective
terms.  As of the current  date,  all of the 3,000  shares of Series A Preferred
Stock and 4,180  shares of Series B Preferred  Stock  issued by the Company have
been fully converted resulting in the issuance of 1,958,984 and 3,172,239 shares
of Common Stock, respectively.

         In May 1998, the Company placed 375 shares of Series C Preferred  Stock
and received cash proceeds of $375,000 from this issuance. No shares of Series C
Preferred Stock have been converted as of the date hereof.

         Under the terms of the Company's  Articles of Incorporation,  the Board
of Directors may determine the rights,  preferences,  and terms of the Company's
authorized  but  unissued  shares of  preferred  stock.  During  the year  ended
December  31,  1996,  the Company  issued  100,000  warrants of Common  Stock in
exchange  for  services  provided  by  an  independent  contractor,   for  which
compensation  expense of $125,489 was  recorded for the year ended  December 31,
1997.  On June 30,  1997 and  November  12,  1997,  the  Company  granted to the
underwriters  of the  Series A  Preferred  Stock and  Series B  Preferred  Stock
warrants  to  purchase a total of 97,860  shares of Common  Stock at prices that
range from $3.44 to $4.50 per share.  For the year ended  December 31, 1997, the
Company  recorded  approximately  $96,000 as a reduction of proceeds  from these
preferred stock offerings.

Outstanding Warrants:

         At December 31,  1997,  outstanding  warrants  pursuant to the IPO were
2,415,000 and  outstanding  warrants  pursuant to the conversion of the November
1996 Debentures and the April 1997  Debentures  were 1,431,427.  These 3,846,427
warrants  originally  entitle the holder to purchase one share of the  Company's
Common Stock at an exercise  price of $9.00 and expire on July 17,  1999.  These
warrants  contain  anti-dilution  provisions that, upon issuance of the Series A
Preferred  Stock and the Series B Preferred  Stock,  have adjusted the number of
shares  that can be  purchased  with  one  warrant  to  $1.19,  resulting  in an
effective  exercise  price of $7.55,  and 4,583,402  shares that would be issued
upon full conversion of the warrants.

6.       Stock Options:

         On April 18, 1996, the Board of Directors  approved,  effective January
1, 1996, the Company's 1996 Omnibus Stock Incentive Plan (the "Plan"). Under the
Plan,  the Company has reserved  650,000  shares of Common Stock for issuance of
both  incentive and  non-qualified  options,  restricted  stock awards and stock
appreciation  rights  ("SARs").  The Plan is  administered  by the  Compensation
Committee of the Board of Directors.  At the annual meeting of  stockholders  on
August 28, 1997,  Company  stockholders  approved the 1997 Stock Incentive Plan,
which provides for up to 1,650,000  shares of the Company's  stock.  Under these
plans,  Options generally become exercisable,  beginning one year after the date
granted,  in five  equal  annual  installments.  No option  may be  granted at a
priceless than the stock's fair market value on the date of the grant.

         Prior to the approved Plan, the Company's  Board of Directors  approved
250,000 of non-Plan stock options which become  exercisable,  beginning one year
after the date granted, in five equal annual installments.

         Information on options is as follows:

         At December 31, 1997,  weighted average remaining  contractual life for
options outstanding was 3.69 years. The fair value of the options granted during
the years  ended  December  31,  1997 and 1996 was  $1,246,600  and  $1,504,643,
respectively.

         During the six months ended June 30, 1998, the Company canceled 575,380
(unaudited) stock options with exercise prices ranging from $0.01 (unaudited) to
$6.00 (unaudited) per share.

         In October  1996,  the  Financial  Accounting  Standards  Board  issued
Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation"  ("SFAS No.  123")  effective  for fiscal  years  beginning  after
December 15, 1996. SFAS No. 123 established  financial  accounting and reporting
standards  for  stock-based  compensation  plans.  The  Company  has adopted the
disclosure-only provisions of SFAS No. 123. In accordance with the provisions of
SFAS No. 123, the Company applies APB Opinion 25 and related  interpretations in
accounting  for its  Plan  and,  accordingly,  does not  recognize  compensation
expense.

         Had  compensation  expense for the Company's plan been determined based
on the fair value at the grant date for awards in 1997 and 1996  consistent with
the  provisions  of SFAS No. 123, the Company's net loss and net loss per common
and common equivalent  shares  outstanding would have been the pro forma amounts
indicated below:

Net loss per share - pro forma........   $       (0.79)    $       (0.50)
 
         The fair value of each option  grant is  estimated on the date of grant
using   the   Black-Scholes   option-   pricing   model   with   the   following
weighted-average assumptions used for grants in 1997 and 1996: dividend yield of
0%;  expected  volatility of 60%;  risk-free  interest rate of 6.41% in 1997 and
5.92% in 1996; and expected lives of 3 years.

8.       Licensing Agreement:

         In March  1996,  the Company  entered  into a  non-exclusive  five-year
licensing agreement with Rockwell International. Pursuant to this agreement, the
Company was granted a price reduction of $1,395,000  related to a purchase order
issued in 1996 and  received  an  initial  cash  payment  of  $300,000  that was
recorded as deferred  licensing  revenue and is being recognized as revenue on a
straight-line  basis over the five year term. Revenue of $50,000 related to this
licensing  agreement was recognized for the year ended December 31, 1996. During
the year ended  December 31, 1997, the Company's  licensee  informed the Company
that as a result of the restructuring of its business  operations,  the licensee
had elected to not continue with its business  activities  under the license.  A
portion of the consideration  received by the Company in March 1996 for granting
this license was a $300,000 cash payment, which the Company recorded as deferred
license  revenue and was amortizing  this amount over a five year period.  Given
the licensee's stated intent to not to continue  conducting  business operations
under the license,  the remaining  deferred  licensing revenue of $250,000 as of
December 31, 1996, was recorded as revenue in the year ended December 31, 1997.


9.       Income Taxes:

         For the year ended  December  31,  1997 no income tax  benefit has been
provided  because the losses  could not be carried back and  realization  of the
benefit of the net operating losses carried forward was not assured. At December
31, 1997, the Company has approximately  $16,026,000 of net operating loss carry
forwards for federal  income tax purposes.  These losses expire in 2012. The use
of these carry  forwards may be limited in any one year under  Internal  Revenue
Code Section 382 if  significant  ownership  changes  occurring the future.  Net
deferred tax assets are comprised of the following:

10.      Commitments and Contingencies:

Lease Commitments:

         During  1994  and  1996,   the  Company  began  leasing  its  operating
facilities and certain  equipment  under various  operating  leases  expiring on
various  dates  through  2001.  Future  minimum  payments  under   noncancelable
operating leases at December 31, 1997 are:


Year Ending December 31,

2001.....................................               2,721
2002.....................................                   -

         Total rental expense  charged to operations for the year ended December
31,1997 and December 31, 1996 was $258,071 and $202,812, respectively.

Purchase Agreements

         The  Company  has  agreements   with  certain   suppliers  to  purchase
specialized parts and components  necessary to produce the Mobile  Assistant(R).
Failure  of any of these  parties  to comply  with the terms and  conditions  of
existing agreements could adversely affect the Company's ability to complete and
deliver Mobile  Assistant(R)  units.  The Company is engaged in discussions with
the supplier of the computing unit for its 133P model of the Mobile Assistant(R)
regarding  direct  assumption by the Company of certain  components for the 133P
currently held by this supplier.  While the outcome of these  discussions is not
certain, if the Company were to assume ownership of the maximum amounts of these
components,  approximately  $600,000  would be added to  inventory  and accounts
payable would increase by the same amount.

Patents

         The  Company   considers  its  patents,   trade   secrets,   and  other
intellectual  property  and other  proprietary  information  to be an  important
factor in its business  prospects.  In September  1995,  the Company  received a
notification from the United States Patent and Trademark Office ("PTO") entitled
"office action in  re-examination"  which  indicated  that the Company's  claims
under  its  existing  patent  for  the  Mobile   Assistant(R)  were  subject  to
re-examination and had been preliminary rejected.  During 1996, this preliminary
rejection  was over turned.  In April 1997 a second  re-examination  request was
filed  with the PTO and the  Company  received  a  notification  from the United
States  Patent  and  Trademark   Office  ("PTO")   entitled  "office  action  in
re-examination"  which  indicated  that the Company's  claims under its existing
patent for the Mobile  Assistant(R) were subject to re-examination  and had been
preliminary rejected. During 1997, this preliminary rejection was overturned. In
October  1996,  the  Company  filed a  patent  application  covering  additional
embodiments and extensions of the technologies used in the Mobile  Assistant(R).
In addition,  eight additional patent  applications have been filed with the PTO
since the Company's IPO.

Commitments (unaudited)

         The Company  entered into a Memorandum  of  Understanding  ("MOU") with
Sony Digital  Products  ("SODP") on May 14, 1998.  This agreement  obligates the
Company to reimburse  SODP Yen 100 million  over a ten month  period  commencing
April 1998.  These  payments  are  reimbursements  to SODP for  engineering  and
development of the Company's Mobile Assistant IV(TM). The Company,  through June
1998, has remitted to SODP

                                      F- 15

<PAGE>



Yen 15 million under the  Memorandum  of  Understanding  in accordance  with the
payment  terms.  The  balance of the  payments  and the related  recognition  of
expense will occur as the services are provided by SODP to the Company.

11.      Legal Proceedings:

         On March 19, 1998,  Matrix  Corporation (see "Key  Suppliers")  filed a
summons  against  the  Company  in the United  States  District  Court,  Eastern
District  of  North  Carolina,  alleging  that:  Matrix  has been  damaged  by a
purported  breach of the December  Agreement  by the  Company;  that the Company
should return all goods shipped by Matrix under both the June  Agreement and the
December Agreement;  that the Company did not intend to comply with the December
Agreement and therefore the governing  contract  between the two entities should
revert to the June  Agreement.  In  addition,  this  summons  requests  that any
damages  incurred by Matrix as a result of this purported  breach of contract be
trebled.  The Company and its legal counsel have initiated a thorough  review of
these allegations and intend to file a counterclaim  against Matrix stating that
Matrix failed to perform to the  requirements of both the June Agreement and the
December  Agreement  and that  Xybernaut  has been  damaged  by this  failure to
perform.  While  there  can  be no  assurance  of  the  outcome  of  this  legal
proceeding,  the  Company's  management  believes  that the claims by Matrix are
groundless  and that the impact of this legal  proceeding  will not be adversely
material to the Company's operations.  The maximum amount payable by the Company
under the December  Agreement if Matrix performs  defined tasks is approximately
$250,000  and the  maximum  amount of  inventory  that  could be  assumed by the
Company under the December Agreement is approximately $600,000.


12.      Related Party Transactions:

         The Company  uses a director  of the Company as its patent  counsel and
paid  cash  to  this  director  for  fees  and   reimbursement  of  expenses  of
approximately$276,000  in 1997 and for  reimbursement  of expenses of $93,250 in
1996. An individual  who was a director of the Company  through  August 1997 was
paid$20,750  during 1997 for consulting  services pursuant to a contract between
that director and the Company.  A director of the Company serves as a consultant
to the Company and during 1997 was paid $305,000 in consulting  payments for the
years 1996 and 1997 and $111,000 as reimbursement  for expenses  incurred during
those two  years.  The  Company  accrued,  but did not pay in cash,  $97,800  in
salaries  and  automobile  allowances  payable to a director  of the Company for
services  provided to Tech  Virginia.  The Company paid  $172,000 as advances on
commissions and expenses to an individual consultant who is an uncle by marriage
to the  President of the Company.  During 1997,  the Company paid  approximately
$81,000 for sales and marketing  consulting  fees and expenses to two members of
the SBS software center in Germany and the Company sold  approximately  $135,000
of products to the SBS software center during this period.


13.      Concentration of Credit Risk Arising from Cash Deposits:

         The  Company's  December  31,  1997  cash and cash  equivalent  balance
includes  approximately $1.0 million of cash invested in a pool of United States
Government and Agency Securities.  The amount in excess of insurance provided by
the Federal Deposit Insurance Company is approximately $900,000.

                                    PART II.
                     INFORMATION NOT REQUIRED IN PROSPECTUS

Item 24.  Indemnification of Directors and Officers

         Section  145 of the  General  Corporation  Law of the State of Delaware
(the "DGCL") provides,  in general,  that a corporation  incorporated  under the
laws of the State of Delaware, such as the registrant,  may indemnify any person
who was or is a party or is  threatened  to be made a party  to any  threatened,
pending or completed action,  suit or proceeding (other than a derivative action
by or in the right of the corporation) by reason of the fact that such person is
or was a director,  officer, employee or agent of the corporation,  or is or was
serving at the request of the  corporation as a director,  officer,  employee or
agent of another  enterprise,  against  expenses  (including  attorneys'  fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
by such person in connection with such action, suit or proceeding if such person
acted in good faith and in a manner such person reasonably  believed to be in or
not opposed to the best interests of the  corporation,  and, with respect to any
criminal action or proceeding,  had no reasonable cause to believe such person's
conduct was unlawful. In the case of a derivative action, a Delaware corporation
may indemnify  any such person  against  expenses  (including  attorneys'  fees)
actually and reasonably  incurred by such person in connection  with the defense
or settlement of such action or suit if such person acted in good faith and in a
manner  such  person  reasonably  believed  to be in or not  opposed to the best
interests of the corporation,  except that no  indemnification  shall be made in
respect of any claim,  issue or matter as to which such  person  shall have been
adjudged to be liable to the corporation  unless and only to the extent that the
Court of  Chancery  of the State of  Delaware  or any other  court in which such
action was brought  determines such person is fairly and reasonably  entitled to
indemnity for such expenses.

   
         The Company's  Certificate  of  Incorporation  provides that  directors
shall not be  personally  liable  for  monetary  damages  to the  Company or our
stockholders  for breach of fiduciary  duty as a director,  except for liability
resulting from a breach of the director's  duty of loyalty to the Company or our
stockholders,  intentional  misconduct  or wilful  violation of law,  actions or
inactions not in good faith, an unlawful stock purchase or payment of a dividend
under Delaware law, or  transactions  from which the director  derives  improper
personal benefit.  Such limitation of liability does not affect the availability
of equitable  remedies such as injunctive  relief or  rescission.  The Company's
Certificate  of  Incorporation  also  authorizes  the Company to  indemnify  our
officers, directors and other agents, by bylaws, agreements or otherwise, to the
fullest  extent  permitted  under  Delaware law. The Company has entered into an
Indemnification  Agreement (the  "Indemnification  Agreement")  with each of our
directors  and officers  which may, in some cases,  be broader than the specific
indemnification   provisions   contained  in  the   Company's   Certificate   of
Incorporation or as otherwise permitted under Delaware law. Each Indemnification
Agreement  may require  the  Company,  among other  things,  to  indemnify  such
officers and directors  against certain  liabilities that may arise by reason of
their status or service as a director or officer,  against  liabilities  arising
from willful  misconduct  of a culpable  nature,  and to obtain  directors'  and
officers' liability insurance if available on reasonable terms.
    

         The Company  maintains a directors and officers  liability  policy with
Genesis  Insurance  Company that contains a limit of liability of $3,000,000 per
policy year.

Item 26.  Recent Sales of Unregistered Securities

         The  following  sets  forth  certain  information  regarding  sales  of
securities  of the Company  issued  within the past three years,  which were not
registered  pursuant to the Securities Act of 1933, as amended (the  "Securities
Act").

         In May 1998, the Company  completed a $750,000 private  placement of an
aggregate of 375 shares of the  Company's  Series C Preferred  Stock,  par value
$0.01 per share ("Series C Preferred  Stock") and 110,294 shares of Common Stock
with  institutional  investors  who had formerly  invested in the  Company.  The
110,294  shares of  Common  Stock  issued  under  this  private  placement  were
unregistered,  restricted  shares.  The  shares of Common  Stock  issuable  upon
conversion   of  the  Series  C  Preferred  are  the  subject  of  an  effective
registration statement of the Company.

         In June 1998, the Company completed a $1,000,000 private placement with
an institutional  investor who had formerly invested in the Company in which the
Company issued 153,846  unregistered  shares of Common Stock at a price of $6.50
per share.

   
         In October  1998,  we issued  216,017  shares of Common Stock under the
interim  financing  arrangement  with the Investor  from which we have  received
$900,000   in  gross   proceeds.   The   purchase   price  of  such  shares  was
$4.166.__________________.
    

         In  December  1997,  two  employees  of the Company  exercised  options
granted to them for an aggregate of 150,000  shares of Common  Stock.  No shares
have been issued under the  Company's  1996  Omnibus  Stock Option Plan and 1997
Stock Option Plan.

         The securities  listed above were (i) sold pursuant to exemptions  from
registration  under  Section  4(2) of the  Securities  Act  and/or  (ii) sold to
persons who were neither  nationals nor residents of the U.S., and no facilities
or  instrumentalities  of U.S.  interstate commerce were used in connection with
any offer or sale thereof. No underwriter or underwriting discount or commission
was involved in any of such sales.

Item 28.  Undertakings

       The undersigned registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement;

              (i) To include any prospectus  required by Section 10(a)(3) of the
Securities  Act of 1933;  

              (ii) To  reflect  in the  prospectus  any facts or events  arising
after the  effective  date of the  registration  statement  (or the most  recent
post-effective  amendment  thereof)  which,  individually  or in the  aggregate,
represent a fundamental  change in the information set forth in the registration
statement; and

               (iii)To include any material information with respect to the plan
of distribution not previously  disclosed in the  registration  statement or any
material change to such information in the registration statement;

         (2) That,  for the  purpose  of  determining  any  liability  under the
Securities Act of 1933, each such post-effective  amendment that contains a form
of prospectus shall be deemed to be a new registration statement relating to the
securities  offered  therein,  and the offering of such  securities at that time
shall be deemed to be the initial bona fide offering thereof; and

         (3) To remove from registration by means of a post-effective  amendment
any of the securities being registered which remain unsold at the termination of
the offering.

   
         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 (the "Act") may be permitted to directors,  officers and controlling
persons of the Registrant pursuant to the foregoing provisions,
    

                                      II-3
<PAGE>



   
or  otherwise,  the  Registrant  has been  advised  that in the  opinion  of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the 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
of the  Registrant in  connection  with the  securities  being  registered,  the
Registrant  will,  unless in the  opinion  of our  counsel  the  matter 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 Act and will be  governed  by the final  adjudication  of such
issue.
    

         The  undersigned  Registrant  hereby  undertakes  (i) to provide to the
Underwriter at the closing specified in the Underwriting  Agreement certificates
in  such  denominations  and  registered  in  such  names  as  required  by  the
Underwriter to permit prompt delivery to each purchaser,  (ii) that for purposes
of determining  any liability  under the Securities Act of 1933, the information
omitted from the form of prospectus filed as part of this Registration Statement
in reliance upon Rule 430A and  contained in a form of  prospectus  filed by the
Registrant  pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act
of 1933 shall be deemed to be part of this Registration Statement as of the time
it was  declared  effective,  and (iii) that for  purposes  of  determining  any
liability under the Securities Act of 1933, each  post-effective  amendment that
contains a form of prospectus shall be deemed to be a new Registration Statement
relating to the securities offered therein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

                  conclusive on all parties.

                           (e)  Nothing  contained  in  this  Article  shall  be
                  construed  to  relieve  any  Interested  Stockholder  from any
                  fiduciary obligation imposed by law.

                           (f) The fact that any Business  Combination  complies

                  Notwithstanding  any other  provisions of this  Certificate of
                  Incorporation   or  the   Bylaws  of  the   Corporation   (and
                  notwithstanding  the fact that a lesser percentage or separate
                  class  vote  may be  specified  by law,  this  Certificate  of

understandings  between the stockholder and each nominee and any other person or
persons  (naming  such person or persons)  pursuant to which the  nomination  or
nominations are to be made by the stockholder;

matter of business to be proposed by such stockholder as would be required to be
included  in a  proxy  statement  filed  pursuant  to  the  proxy  rules  of the

to be nominated, or the matter been proposed, or intended to be proposed, by the
Board of Directors, and such other information about the nominee as the Board of
Directors deems appropriate, including, without limitation, the nominee's age,


<PAGE>



business and residence addresses,  principal occupation and the class and number
of shares of Common  Stock or other  capital  stock of the Company  beneficially
owned by the  nominee,  or such  other  information  about  the  business  to be
proposed and about the  stockholder  making such  business  proposal  before the
annual meeting as the Board of Directors deems appropriate,  including,  without
limitation,  the class and  number  of shares of Common  Stock or other  capital
stock beneficially owned by such stockholder; and

                  (e) if  applicable,  the  consent of each  nominee to serve as

business not made in compliance with the foregoing procedure.

otherwise provided in the resolutions of the Board of Directors  designating any
series of Preferred  Stock,  any action required or permitted to be taken by the
stockholders  of the  corporation  must be effected  at a duly called  annual or
special meeting of stockholders  and may not be effected by a consent in writing
by any such stockholders.

defined),  voting  together as a single  class,  and (2) at least 66 2/3% of the
votes entitled to be cast by holders of the Voting Stock, excluding shares owned

shall be required notwithstanding the fact that no vote may be required, or that
a lesser  percentage or separate  class vote may be specified,  by law or in any
agreement with any national securities exchange or otherwise.

applicable to any particular Business Combination, and such Business Combination
shall  require only such  affirmative  vote, if any, as is required by law or by
any other provision of this  Certificate of  Incorporation  or the Bylaws of the
Corporation,  or any agreement  with any national  securities  exchange,  if the
Business  Combination  shall  have been  approved  by a majority  (whether  such
approval  is made  prior  to or  subsequent  to the  acquisition  of  beneficial
ownership  of the  Voting  Stock  that  caused the  Interested  Stockholder  (as
hereinafter  defined) to become an  Interested  Stockholder)  of the  Continuing
Directors (as hereinafter defined).

         of  any  class  of  equity  security  is  beneficially   owned  by  the

         of  Interested  Stockholder,  the term  "Subsidiary"  shall mean only a
         company  of which a  majority  of each  class  of  equity  security  is
         beneficially owned by the Corporation.

                           8.  "Continuing  Director"  means  any  member of the
         Board of Directors of the Corporation, while such person is a member of
         the  Board  of  Directors,  who  is  not  an  Affiliate,  Associate  or
         representative  of the Interested  Stockholder  and was a member of the
         Board of Directors  prior to the time that the  Interested  Stockholder
         became an  Interested  Stockholder,  and any  successor of a Continuing
         Director  while such  successor is a member of the Board of  Directors,
         provided  that  such  successor  is  not  an  Affiliate,  Associate  or
         representative  of the  Interested  Stockholder  and is  recommended or
         elected to succeed the Continuing  Director by a majority of Continuing
         Directors.

                  (d) A  majority  of the  Continuing  Directors  shall have the

Interested  Stockholder,  (ii) the  number of shares of  Capital  Stock or other
securities  beneficially  owned by any person,  and (iii) whether a person is an
Affiliate  or Associate of another.  Any such  determination  made in good faith
shall be binding and conclusive on all parties.

                  (e) Nothing  contained in this  Article  shall be construed to
relieve any Interested Stockholder from any fiduciary obligation imposed by law.

                  (f) The fact that any Business  Combination  complies with the
provisions  of Section (b) of this Article  shall not be construed to impose any
fiduciary duty,  obligation or responsibility on the Board of Directors,  or any
member thereof to approve such Business Combination or recommend its adoption or
approval  to the  stockholders  or the  Corporation,  nor shall such  compliance
limit,  prohibit or otherwise restrict in any manner the Board of Directors,  or
any member  thereof,  with respect to  evaluations  of or actions and  responses
taken  with  respect to such  Business  Combination.  Notwithstanding  any other
provisions of this Certificate of Incorporation or the Bylaws of the Corporation
(and  notwithstanding  the fact that a lesser  percentage or separate class vote
may be specified by law, this  Certificate of Incorporation or the Bylaws of the
Corporation),  the  affirmative  vote of the  holders  of not less  than  eighty
percent (80%) of the votes to be cast by the holders of all the then outstanding
shares of Voting Stock,  voting together as a single class, shall be required to
amend or repeal, or adopt any provisions inconsistent with this Article.

                  Section 2.1 Number and Term of Office. The business, property,
and affairs of the  Corporation  shall be managed by or under the direction of a
Board of Directors.  The Board of Directors  shall consist of not fewer than six
(6) members and not more than twelve (12) members, with the number of authorized
directors being  initially  fixed at ten (10),  which number may be changed from
time  to  time  by a  resolution  of  the  Board  of  Directors  adopted  by the
affirmative  vote of at least a  majority  of the  total  number  of  authorized
directors most recently fixed by the Board of Directors,  except in each case as
may be provided pursuant to


<PAGE>



resolutions of the Board of Directors, adopted pursuant to the provisions of the
Certificate of  Incorporation,  establishing  any series of Preferred  Stock and
granting to holders of shares of such series of Preferred  Stock rights to elect
additional directors under specified circumstances.

         The Board of Directors shall be divided into three classes,  designated
Class I, Class II and Class III. Such classes shall be as nearly equal in number
as the then total number of directors constituting the entire Board permits.

         The  directors  shall be elected by the  holders of shares  entitled to
vote  thereon  at the  annual  meeting of  stockholders,  and each  shall  serve
(subject to the  provisions  of Article IV) until his  respective  successor has
been  elected  and  qualified.   At  the  August  28,  1997  annual  meeting  of
stockholders,  Class I, Class II and Class III  directors  shall be elected  for
initial  terms  expiring  at the next  succeeding  annual  meeting,  the  second
succeeding  annual and the third succeeding  annual meeting,  respectively,  and
until their  respective  successors  are elected and  qualified.  At each annual
meeting of stockholders  after August 28, 1997, the directors  chosen to succeed
those in the class whose terms then expire shall be elected by the  stockholders
for terms expiring at the third  succeeding  annual meeting after their election
and until their respective  successors are elected and qualified.  Newly created
directorships  or any decrease in  directorships  resulting  from  increases and
decreases in the number of directors  shall be so apportioned  among the classes
as to make all the classes as nearly equal in number as possible; provided, that
when the Board increases the number of directors and fills the vacancies created
thereby  such  director  will hold  office for the term  expiring  at the annual
meeting  of  stockholders  for the term of the  class to which  they  have  been
elected expires.

                  Section  2.2  Meetings.  Regular  meetings  of  the  Board  of
Directors  may be held without  notice at such time and place as shall from time
to time be determined by the Board.  Special  meetings of the Board of Directors
shall be held at such time and place as shall be designated in the notice of the
meeting  whenever  called by the  President or by one of the  directors  then in
office.

                  Section 2.3 Notice of Special Meetings.  The Secretary,  or in
his  absence  any other  officer of the  corporation,  shall give each  director
notice of the time and place of  holding  of  special  meetings  of the Board of
Directors  at least  twenty-four  hours  before  the  meeting,  whether by mail,
telegram,  cable, radiogram, or personal service. Unless otherwise stated in the
notice  thereof,  any and all business may be transacted at any meeting  without
specification of such business in the notice.

                  Section 2.4 Quorum and Organization of Meetings. A majority of
the total number of members of the Board of Directors as  constituted  from time
to time shall  constitute a quorum for the  transaction of business,  but, if at
any meeting of the Board of Directors  (whether or not adjourned from a previous
meeting) there shall be less than a quorum present,  a majority of those present

                  10.  Saturdays,   Sundays,  Holidays,  etc.  If  the  last  or
appointed  day for the  taking  of any  action  or the  expiration  of any right

day not a legal holiday.

                  11.      Effect of Certain Events.
                  (a) If at any  time  the  Company  proposes  (i)  to  sell  or
otherwise  convey  all or  substantially  all of its  assets or (ii) to effect a
transaction  (by merger or otherwise) in which more than 50% of the voting power
of the Company is disposed of (collectively, a "Sale or Merger Transaction"), in
which the  consideration  to be  received  by the  Company  or its  shareholders
consists solely of cash, then the Warrant shall terminate if the Warrant has not
been exercised by the effective date of such transaction, the Company shall give
the holder of this Warrant thirty (30) days' notice of such  termination  and of
the proposed effective date of the transaction.

                  (b) In case the  Company  shall  at any time  effect a sale or
merger  transaction in which the  consideration to be received by the Company or
its shareholders  consists in part of consideration  other than cash, the holder
of this Warrant shall have the right thereafter to purchase, by exercise of this
Warrant and payment of the aggregate  Exercise Price in effect immediately prior
to such action,  the kind and amount of shares and other securities and property
which it would have owned or have been  entitled to receive  after the happening
of such transaction had this Warrant been exercised immediately prior thereto.

                  (c) The  Company  agrees  that  the  Warrant  Shares  shall be
included in the registration  statement to be filed in accordance with the terms
of the Agreement.

Warrant and the Exercise Price shall be subject to adjustment  from time to time
upon the happening of any of the following.

shares  of Common  Stock or make a  distribution  in  shares of Common  Stock to
holders of its outstanding  Common Stock, (ii) subdivide its outstanding  shares
of Common  Stock,  (iii) combine its  outstanding  shares of Common Stock into a
smaller number of shares of Common Stock or (iv) issue any shares of its capital
stock in a  reclassification  of the  Common  Stock,  then the number of Warrant
Shares purchasable upon exercise of this Warrant immediately prior thereto shall
be adjusted so that the holder of this Warrant  shall be entitled to receive the
kind and number of Warrant  Shares or other  securities  of the Company which he
would  have  owned or have  been  entitled  to  receive  had such  Warrant  been
exercised in advance  thereof.  Upon each such adjustment of the kind and number
of Warrant  Shares or other  securities  of the  Company  which are  purchasable
hereunder,  the holder of this Warrant shall  thereafter be entitled to purchase
the number of Warrant Shares or other securities  resulting from such adjustment
at an  Exercise  Price per such  Warrant  Share or other  security  obtained  by
multiplying the Exercise Price in effect immediately prior to such adjustment by
the number of Warrant Shares  purchasable  pursuant hereto  immediately prior to
such adjustment and dividing by the number of Warrant Shares or other securities
of the Company  resulting from such  adjustment.  An adjustment made pursuant to
this paragraph shall become  effective  immediately  after the effective date of
such event retroactive to the record date, if any, for such event.

                  13.  Voluntary  Adjustment by the Company.  The Company may at
any time during the term of this Warrant, reduce the then current Exercise Price
to any  amount  and for any period of time  deemed  appropriate  by the Board of
Directors of the Company.

                  14.  Notice of  Adjustment.  Whenever  the  number of  Warrant
Shares or number or kind of securities or other  property  purchasable  upon the
exercise of this Warrant or the Exercise Price is adjusted, as


<PAGE>



herein  provided,  the Company  shall  promptly  mail by registered or certified
mail,  return  receipt  requested,  to the holder of this Warrant notice of such
adjustment or adjustments  setting forth the number of Warrant Shares (and other
securities  or property)  purchasable  upon the exercise of this Warrant and the
Exercise Price of such Warrant Shares (and other  securities or property)  after
such  adjustment,  setting forth a brief  statement of the facts  requiring such
adjustment and setting forth the  computation by which such adjustment was made.
Such notice, in absence of manifest error,  shall be conclusive  evidence of the
correctness of such adjustment.

                  15. Authorized  Shares.  The Company covenants that during the
period the Warrant is  outstanding,  it will  reserve  from its  authorized  and
unissued Common Stock a sufficient  number of shares to provide for the issuance
of the  Warrant  Shares  upon the  exercise of any  purchase  rights  under this
Warrant.  The Company further  covenants that its issuance of this Warrant shall
constitute  full  authority  to its  officers  who are charged  with the duty of
executing stock certificates to execute and issue the necessary certificates for
the Warrant Shares upon the exercise of the purchase  rights under this Warrant.
The Company will take all such  reasonable  action as may be necessary to assure
that such Warrant Shares may be issued as provided  herein without  violation of
any applicable law or regulation, or of any requirements of the NASDAQ Small Cap
Stock Market or any domestic securities exchange upon which the Common Stock may
be listed.
                  16.      Miscellaneous.
                  (a) Issue Date;  Jurisdiction.  The provisions of this Warrant
shall be  construed  and shall be given effect in all respects as if it had been
issued and  delivered by the Company on the date hereof.  This Warrant  shall be
binding  upon any  successors  or assigns of the  Company.  This  Warrant  shall
constitute a contract  under the laws of New York without regard to its conflict
of law, principles or rules, and be subject to arbitration pursuant to the terms
set forth in the Agreement.

                  (b)  Restrictions.  The holder  hereof  acknowledges  that the
Warrant Shares  acquired upon the exercise of this Warrant,  if not  registered,
will have restrictions upon resale imposed by state and federal securities laws.
Each  certificate  representing  the  Warrant  Shares  issued to the Holder upon
exercise will bear the following legend:

                  "THE SECURITIES  EVIDENCED BY THIS  CERTIFICATE  HAVE NOT BEEN
         REGISTERED  UNDER THE U.S.  SECURITIES  ACT OF 1933,  AS  AMENDED  (THE
         "SECURITIES  ACT"),  OR ANY OTHER  APPLICABLE  SECURITIES LAWS AND HAVE
         BEEN  ISSUED  IN  RELIANCE  UPON AN  EXEMPTION  FROM  THE  REGISTRATION
         REQUIREMENTS  OF THE  SECURITIES  ACT AND SUCH OTHER  SECURITIES  LAWS.
         NEITHER THIS SECURITY NOR ANY INTEREST OR  PARTICIPATION  HEREIN MAY BE
         REOFFERED,   SOLD,   ASSIGNED,   TRANSFERRED,    PLEDGED,   ENCUMBERED,
         HYPOTHECATED OR OTHERWISE  DISPOSED OF, EXCEPT PURSUANT TO AN EFFECTIVE
         REGISTRATION  STATEMENT  UNDER  THE  SECURITIES  ACT OR  PURSUANT  TO A
         TRANSACTION THAT IS EXEMPT FROM, OR NOT SUBJECT TO, SUCH REGISTRATION".

                  (c) Modification  and Waiver.  This Warrant and any provisions
hereof may be changed, waived, discharged or terminated only by an instrument in
writing signed by the party against which enforcement of the same is sought.

                                                                   Exhibit 10.12


                            1997 STOCK INCENTIVE PLAN

                                       of

                              XYBERNAUT CORPORATION

                  1.  PURPOSES  OF THE  PLAN.  This  stock  incentive  plan (the
"Plan")  is  designed  to  provide  an  incentive  to key  employees  (including
directors and officers who are key employees)  and to consultants  and directors
who are not  employees of XYBERNAUT  CORPORATION,  a Delaware  corporation  (the
"Company"),  or any of its  Subsidiaries  (as defined in  Paragraph  18), and to
offer an additional  inducement  in obtaining the services of such persons.  The
Plan provides for the grant of "incentive  stock  options"  ("ISOs")  within the
meaning of Section 422 of the  Internal  Revenue  Code of 1986,  as amended (the
"Code"),  nonqualified  stock  options  which do not qualify as ISOs  ("NQSOs"),
stock appreciation rights ("SARs") and stock of the Company which may be subject
to contingencies or restrictions (collectively,  "Awards"). The Company makes no
representation or warranty,  express or implied,  as to the qualification of any
option as an "incentive stock option" under the Code.

                  2. STOCK  SUBJECT TO THE PLAN.  Subject to the  provisions  of
Paragraph 11, the aggregate number of shares of Common Stock, $.01 par value per
share, of the Company ("Common Stock") for which Awards may be granted under the
Plan  shall not  exceed  1,650,000.  Such  shares of Common  Stock  may,  in the
discretion of the Board of Directors of the Company (the "Board of  Directors"),
consist either in whole or in part of authorized  but unissued  shares of Common
Stock or shares of Common Stock held in the treasury of the Company.  Subject to
the  provisions of Paragraph 12, any shares of Common Stock subject to an option
or SAR which for any reason expires, is canceled or is terminated unexercised or
which ceases for any reason to be exercisable or a restricted  stock Award which
for any reason is  forfeited,  shall again become  available for the granting of
Awards  under the Plan.  The Company  shall at all times  during the term of the
Plan reserve and keep available such number of shares of Common Stock as will be
sufficient to satisfy the requirements of the Plan.

                  3.  ADMINISTRATION OF THE PLAN. The Plan shall be administered
by the Board of Directors or a committee of the Board of Directors consisting of
not less than two  directors,  each of whom shall be a  "non-employee  director"
within the meaning of Rule 16b-3 (as defined in Paragraph 18) (collectively, the
"Committee").  Unless  otherwise  provided  in the  By-laws of the Company or by
resolution of the Board of Directors, a majority of the members of the Committee
shall constitute a quorum,  and the acts of a majority of the members present at
any  meeting at which a quorum is present,  and any acts  approved in writing by
all members without a meeting, shall be the acts of the Committee.

                  Subject to the express  provisions of the Plan,  the Committee
shall  have  the  authority,  in its  sole  discretion,  to  determine:  the key
employees,  consultants and directors who shall be granted  Awards;  the type of
Award to be granted;  the times when an Award  shall be  granted;  the number of
shares of Common Stock to be subject to each Award;  the term of each option and
SAR; the date each option and SAR shall become exercisable; whether an option or
SAR shall be exercisable in whole or in  installments  and, if in  installments,
the number of shares of Common Stock to be subject to each installment,  whether
the installments  shall be cumulative,  the date each  installment  shall become
exercisable and the term of each installment; whether to accelerate the date of





<PAGE>



exercise of any option or SAR or installment  thereof;  whether shares of Common
Stock may be issued  upon the  exercise  of an option as partly paid and, if so,
the dates when future  installments  of the exercise  price shall become due and
the amounts of such installments; the exercise price of each option and the base
price of each SAR; the price, if any, to be paid for a share Award;  the form of
payment of the exercise price of an option; the form of payment upon exercise of
an SAR;  whether to restrict the sale or other  disposition  of a stock Award or
the shares of Common Stock  acquired  upon the exercise of an option or SAR and,
if so, to determine  whether such  contingencies  and restrictions have been met
and  whether  and  under  what  conditions  to  waive  any such  contingency  or
restriction;  whether and under what  conditions  to subject all or a portion of
the grant or exercise  of an option or SAR,  the vesting of a stock Award or the
shares acquired  pursuant to the exercise of an option or SAR to the fulfillment
of certain  contingencies or restrictions as specified in the contract  referred
to in  Paragraph  10 hereof  (the  "Contract"),  including  without  limitation,
contingencies  or  restrictions  relating  to  entering  into a covenant  not to
compete with the  Company,  any of its  Subsidiaries  or a Parent (as defined in
Paragraph 18), to financial  objectives for the Company, any of its Subsidiaries
or a  Parent,  a  division  of any of the  foregoing,  a  product  line or other
category,  and/or to the period of continued employment of the Award holder with
the Company,  any of its Subsidiaries or a Parent, and to determine whether such
contingencies or restrictions have been met; whether an Award holder is Disabled
(as defined in  Paragraph  18);  the amount,  if any,  necessary  to satisfy the
obligation  of the Company,  a Subsidiary  or Parent to withhold  taxes or other
amounts; the Fair Market Value (as defined in Paragraph 18) of a share of Common
Stock;  to construe the respective  Contracts and the Plan;  with the consent of
the Award  holder,  to cancel or modify an Award,  provided,  that the  modified
provision is permitted to be included in an Award  granted under the Plan on the
date  of  the  modification,  and  further,  provided,  that  in the  case  of a
modification  (within the meaning of Section 424(h) of the Code) of an ISO, such
Award  as  modified  would  be  permitted  to be  granted  on the  date  of such
modification under the terms of the Plan; to prescribe,  amend and rescind rules
and regulations  relating to the Plan; to approve any provision which under Rule
16b-3  requires  the  approval  of  the  Board  of  Directors,  a  committee  of
non-employee  directors  or the  stockholders  to be  exempt  (unless  otherwise
specifically provided herein); and to make all other determinations necessary or
advisable for administering the Plan. Any controversy or claim arising out of or
relating to the Plan,  any Award granted under the Plan or any Contract shall be
determined   unilaterally  by  the  Committee  in  its  sole   discretion.   The
determinations  of the Committee on the matters  referred to in this Paragraph 3
shall be  conclusive  and binding on the parties.  No member or former member of
the Committee  shall be liable for any action,  failure to act or  determination
made in good faith with respect to the Plan or any Award or Contract hereunder.

                  4.       OPTIONS

                           (a)  GRANT.  The  Committee  may  from  time to time,
consistent  with the purposes of the Plan,  grant  options to such key employees
(including officers and directors who are key employees) of, and consultants to,
the  Company or any of its  Subsidiaries,  and such  Outside  Directors,  as the
Committee may  determine,  in its sole  discretion.  Such options  granted shall
cover such number of shares of Common Stock as the Committee may  determine,  in
its sole discretion, as set forth in the applicable Contract; provided, however,
that the maximum number of shares subject to options or SARs that may be granted
to any employee  during any calendar year under the Plan (the "162(m)  Maximum")
shall be 350,000 shares; and further,  provided,  that the aggregate Fair Market
Value  (determined  at the time the option is  granted)  of the shares of Common
Stock for which any eligible  employee may be granted ISOs under the Plan or any
other plan of the Company, of any of its Subsidiaries or of a Parent,  which are
exercisable  for the first time by such optionee  during any calendar year shall
not exceed  $100,000.  Such ISO limitation  shall be applied by taking ISOs into
account in the order in which





<PAGE>



they were granted.  Any option granted in excess of such ISO  limitation  amount
shall be treated as a NQSO to the extent of such excess.

                           (b) EXERCISE PRICE.  The exercise price of the shares
of Common Stock under each option shall be determined by the  Committee,  in its
sole discretion,  as set forth in the applicable  Contract;  provided,  however,
that the  exercise  price  per  share of an ISO  shall not be less than the Fair
Market  Value of a share of  Common  Stock on the date of  grant;  and  further,
provided,  that if,  at the time an ISO is  granted,  the  optionee  owns (or is
deemed to own under Section 424(d) of the Code) stock  possessing  more than 10%
of the total  combined  voting power of all classes of stock of the Company,  of
any of its Subsidiaries or of a Parent, the exercise price per share of such ISO
shall not be less than 110% of the Fair Market  Value of a share of Common Stock
on the date of grant.

                           (c) TERM. The term of each option granted pursuant to
the Plan shall be determined by the Committee,  in its sole  discretion,  as set
forth in the applicable Contract;  provided,  however, that the term of each ISO
shall not exceed 10 years from the date of grant thereof; and further, provided,
that if, at the time an ISO is granted,  the optionee  owns (or is deemed to own
under Section  424(d) of the Code) stock  possessing  more than 10% of the total
combined  voting  power of all  classes of stock of the  Company,  of any of its
Subsidiaries  or of a Parent,  the term of the ISO shall not  exceed  five years
from the date of grant.  Options  shall be  subject to  earlier  termination  as
hereinafter provided.

                           (d) EXERCISE.  An option (or any part or  installment
thereof),  to the extent then exercisable,  shall be exercised by giving written
notice to the Company at its then principal office stating which option is being
exercised,  specifying  the  number of shares of Common  Stock as to which  such
option is being  exercised and  accompanied  by payment in full of the aggregate
exercise price therefor (or the amount due upon exercise if the Contract permits
installment payments) (a) in cash or by certified check or (b) if the applicable
Contract  permits,  with  previously  acquired  shares of Common Stock having an
aggregate  Fair  Market  Value on the date of  exercise  equal to the  aggregate
exercise price of all options being exercised,  or with any combination of cash,
certified  check or shares of Common Stock having such value.  The Company shall
not be required to issue any shares of Common Stock  pursuant to any such option
until all required payments, including any required withholding, have been made.

                  The Committee may, in its sole  discretion,  permit payment of
all or a portion of the exercise  price of an option by delivery by the optionee
of a  properly  executed  notice,  together  with  a  copy  of  his  irrevocable
instructions to a broker  acceptable to the Committee to deliver promptly to the
Company  the amount of sale or loan  proceeds  sufficient  to pay such  exercise
price.  In  connection  therewith,  the  Company may enter into  agreements  for
coordinated procedures with one or more brokerage firms.

                  An optionee entitled to receive Common Stock upon the exercise
of an option  shall not have the rights of a  stockholder  with  respect to such
shares of Common  Stock until the date of issuance  of a stock  certificate  for
such shares or, in the case of uncertificated  shares, until an entry is made on
the books of the Company's  transfer agent  representing such shares;  provided,
however,  that until such stock certificate is issued or book entry is made, any
optionee  using  previously  acquired  shares of Common  Stock in  payment of an
option  exercise price shall  continue to have the rights of a stockholder  with
respect to such previously acquired shares.

                  In no case  may an  option  be  exercised  with  respect  to a
fraction  of a share of Common  Stock.  In no case may a fraction  of a share of
Common Stock be purchased or issued under the Plan.



<PAGE>



                  (e) RELOAD  OPTIONS.  An  optionee  who,  at a time when he is
eligible to be granted options under the Plan,  uses previously  acquired shares
of Common  Stock to  exercise  an  option  granted  under  the Plan (the  "prior
option"),  shall,  upon such exercise,  be automatically  granted an option (the
"reload  option") to purchase  the same number of shares of Common Stock so used
(or if there is not a sufficient  number of shares available for grant under the
Plan  remaining,  such  number  of shares as are then  available).  Such  reload
options  shall be of the same type and have the same  terms as the prior  option
(except  to the  extent  inconsistent  with the  terms of the  Plan);  provided,
however,  that the exercise  price per share of the reload option shall be equal
to the Fair Market  Value of a share of Common Stock on the date of grant of the
reload option, and further, provided, that if the prior option was an ISO and at
the time the reload  option is granted,  the optionee  owns (or is deemed to own
under Section  424(d) of the Code) stock  possessing  more than 10% of the total
combined  voting  power of all  classes of stock of the  Company,  of any of its
Subsidiaries or of a Parent, the exercise price per share shall be equal to 110%
of the Fair Market Value of a share of Common Stock on the date of grant and the
term of such option shall not exceed five years.

                  5.       STOCK APPRECIATION RIGHTS.

                           (a)  GRANT.  The  Committee  may  from  time to time,
consistent  with the  purposes  of the Plan,  grant  SARs to such key  employees
(including officers and directors who are key employees) of, and consultants to,
the  Company or any of its  Subsidiaries,  and such  Outside  Directors,  as the
Committee may determine in its sole discretion.  An SAR shall entitle the holder
thereof to be paid, promptly after exercise, in cash, by check or with shares of
Common Stock  having an  aggregate  Fair Market Value on the date of exercise or
any combination thereof, as determined by the Committee, in its sole discretion,
an amount equal to the excess,  if any, of the Fair Market Value on the exercise
date of the  shares of Common  Stock as to which the SAR is  exercised  over the
base price of such  shares.  The  Contract  may (but shall not be  required  to)
provide for such amount to be multiplied by a performance factor as set forth in
the Contract;  provided,  however,  that such performance  factor shall meet the
requirements for "qualified  performance-based  compensation" within the meaning
of Section 162(m) of the Code.

                           (b) BASE  PRICE.  The base  price  of the  shares  of
Common Stock  subject to each SAR shall be  determined  by the  Committee in its
sole discretion;  provided,  however, that the base price per share shall not be
less than the Fair Market Value of a share of Common Stock on the date of grant.

                           (c) TERM.  The term of each SAR  granted  pursuant to
the Plan shall be determined by the Committee,  in its sole  discretion,  as set
forth in the applicable Contract;  provided,  however, that the term of each SAR
shall not  exceed 10 years  from the date of grant.  SARs  shall be  subject  to
earlier termination as provided in the Plan.

                           (d)  EXERCISE.  An SAR  (or any  part or  installment
thereof),  to the extent then exercisable,  shall be exercised by giving written
notice to the Company at its then  principle  office  stating which SAR is being
exercised and  specifying  the number of shares of Common Stock as to which such
SAR is being exercised.

                  The holder of an SAR who receives  shares of Common Stock upon
the exercise of an SAR shall not have the rights of a  stockholder  with respect
to such shares of Common Stock until the date of issuance of a stock certificate
for such shares or, in the case of uncertificated shares, until an entry is made
on the books of the Company's transfer agent representing such shares.





<PAGE>



                  In no case may an SAR be exercised  with respect to a fraction
of a share of Common Stock.

                  6. RESTRICTED  STOCK. The Committee may from time,  consistent
with  the  purposes  of the  Plan,  grant  shares  of  Common  Stock to such key
employees  (including  officers  and  directors  who are key  employees)  of, or
consultants  to, the Company or any of its  Subsidiaries,  as the  Committee may
determine, in its sole discretion.  The grant may cover such number of shares as
the  Committee  may  determine,  in its sole  discretion,  and require the Award
holder to pay such  price per  share  therefor,  if any,  as the  Committee  may
determine,  in  its  sole  discretion.  Such  shares  may  be  subject  to  such
contingencies  and restrictions as the Committee may determine,  as set forth in
the Contract.  Upon the issuance of the stock  certificate for a share Award, or
in the case of  uncertificated  shares,  the entry on the books of the Company's
transfer agent  representing such shares,  notwithstanding  any contingencies or
restrictions  to which  the  shares  are  subject,  the  Award  holder  shall be
considered  to  be  the  record  owner  of  the  shares,   and  subject  to  the
contingencies and restrictions set forth in the Award,  shall have all rights of
a stockholder of record with respect to such shares, including the right to vote
and to receive  distributions.  Upon the  occurrence of any such  contingency or
restriction,  the Award  holder may be  required  to forfeit all or a portion of
such shares back to the Company.  The shares shall vest in the Award holder when
all of the restrictions and contingencies lapse. Accordingly,  the Committee may
require  that such shares be held by the  Company,  together  with a stock power
duly endorsed in blank by the Award  holder,  until the shares vest in the Award
holder.

                  7.  TERMINATION  OF  RELATIONSHIP.  Except as may otherwise be
expressly provided in the applicable Contract, if an Award holder's relationship
with the Company, its Subsidiaries and Parent as an employee or a consultant has
terminated  for any reason (other than as a result of his death or  Disability),
the Award holder may exercise the options and SARs granted to him as an employee
of, or  consultant  to, the  Company or any of its  Subsidiaries,  to the extent
exercisable  on the date of such  termination,  at any time within  three months
after the date of termination, but not thereafter and in no event after the date
the  Award  would  otherwise  have  expired;  provided,  however,  that  if such
relationship is terminated either (a) for Cause (as defined in Paragraph 18), or
(b) without the consent of the Company, such option shall terminate immediately.

                  For the purposes of the Plan, an employment relationship shall
be  deemed  to  exist  between  an  individual  and  the  Company,  any  of  its
Subsidiaries  or a Parent if, at the time of the  determination,  the individual
was an employee of such  corporation for purposes of Section 422(a) of the Code.
As a result,  an individual on military,  sick leave or other bona fide leave of
absence  shall  continue to be  considered  an employee for purposes of the Plan
during  such leave if the  period of the leave  does not exceed 90 days,  or, if
longer, so long as the individual's right to reemployment with the Company,  any
of its Subsidiaries or a Parent is guaranteed  either by statute or by contract.
If  the  period  of  leave  exceeds  90  days  and  the  individual's  right  to
reemployment  is not  guaranteed  by  statute  or by  contract,  the  employment
relationship shall be deemed to have terminated on the 91st day of such leave.

                  Except  as  may   otherwise  be  expressly   provided  in  the
applicable  Contract,  options  and SARs  granted  under  the Plan  shall not be
affected by any change in the status of the Award holder so long as he continues
to be  an  employee  of,  or a  consultant  to,  the  Company,  or  any  of  its
Subsidiaries or a Parent  (regardless of having changed from one to the other or
having been transferred from one corporation to another).

                  Except  as  may   otherwise  be  expressly   provided  in  the
applicable  Contract,  if an Award holder's  relationship with the Company as an
Outside  Director  ceases for any reason (other than as a result of his death or
Disability)  then options and SARs granted to such holder as an Outside Director
may be exercised, to the





<PAGE>



extent  exercisable  on the date of such  termination,  at any time within three
months after the date of  termination,  but not thereafter and in no event after
the date the Award would otherwise have expired; provided, however, that if such
relationship is terminated for Cause, such Award shall terminate immediately. An
Award  granted to an Outside  Director,  however,  shall not be  affected by the
Award holder becoming an employee of, or consultant to, the Company,  any of its
Subsidiaries or a Parent.

                  Except as may otherwise be expressly provided in the Contract,
upon the  termination of the  relationship of an Award holder as an employee of,
or consultant to, the Company, and its Subsidiaries and Parent, or as an Outside
Director,  for any reason  (including his death or Disability),  the share Award
shall cease any further vesting and the unvested portion of such Award as of the
date of such termination shall be forfeited to the Company for no consideration.

                  Nothing  in the Plan or in any  Award  granted  under the Plan
shall confer on any Award holder any right to continue in the employ of, or as a
consultant  to,  the  Company,  any of its  Subsidiaries  or a  Parent,  or as a
director of the Company,  or interfere in any way with any right of the Company,
any of its Subsidiaries or a Parent to terminate the Award holder's relationship
at any time for any reason whatsoever  without liability to the Company,  any of
its Subsidiaries or a Parent.

                  8. DEATH OR  DISABILITY.  Except as may otherwise be expressly
provided in the applicable Contract,  if an Award holder dies (a) while he is an
employee of, or consultant to, the Company, any of its Subsidiaries or a Parent,
(b) within three months after the termination of such relationship  (unless such
termination  was for Cause or without the consent of the  Company) or (c) within
one year  following  the  termination  of such  relationship  by  reason  of his
Disability,  the options and SARs that were granted to him as an employee of, or
consultant to, the Company or any of its Subsidiaries,  may be exercised, to the
extent  exercisable on the date of his death,  by his Legal  Representative  (as
defined  in  Paragraph  18) at any time  within one year  after  death,  but not
thereafter  and in no event  after  the date the  option  would  otherwise  have
expired.

                  Except  as  may   otherwise  be  expressly   provided  in  the
applicable  Contract,  if an Award holder's  relationship  as an employee of, or
consultant to, the Company,  any of its  Subsidiaries or a Parent has terminated
by reason of his Disability, the options and SARs that were granted to him as an
employee  of, or  consultant  to the Company or any of its  Subsidiaries  may be
exercised,   to  the  extent   exercisable  upon  the  effective  date  of  such
termination, at any time within one year after such date, but not thereafter and
in no event after the date the option would otherwise have expired.

                  Except  as  may   otherwise  be  expressly   provided  in  the
applicable  Contract,  if an Award holder's  relationship as an Outside Director
terminates as a result of his death or Disability,  the options and SARs granted
to him as an Outside Director may be exercised, to the extent exercisable on the
date of such  termination,  at any  time  within  one  year  after  the  date of
termination,  but not  thereafter and in no event after the date the Award would
otherwise have expired.  In the case of the death of the Award holder, the Award
may be exercised by his Legal Representative.

                  9. COMPLIANCE  WITH SECURITIES  LAWS. It is a condition to the
issuance of any share Award and  exercise of any option or SAR that either (a) a
Registration  Statement  under  the  Securities  Act of 1933,  as  amended  (the
"Securities  Act"), with respect to the shares of Common Stock to be issued upon
such grant or exercise  shall be effective  and current at the time of exercise,
or (b) there is an exemption from registration  under the Securities Act for the
issuance of the shares of Common Stock upon such exercise. Nothing





<PAGE>



herein shall be construed as requiring the Company to register shares subject to
any  Award  under  the  Securities  Act or to keep  any  Registration  Statement
effective or current.

                  The  Committee  may  require,  in its  sole  discretion,  as a
condition  to the receipt of an Award or the  exercise of any option or SAR that
the Award  holder  execute and deliver to the  Company his  representations  and
warranties,  in form,  substance and scope satisfactory to the Committee,  which
the  Committee   determines  are  necessary  or  convenient  to  facilitate  the
perfection of an exemption from the registration  requirements of the Securities
Act,  applicable  state securities laws or other legal  requirement,  including,
without limitation, that (a) the shares of Common Stock to be received under the
Award or issued upon the exercise of the option or SAR are being acquired by the
Award holder for his own account, for investment only and not with a view to the
resale or distribution thereof, and (b) any subsequent resale or distribution of
shares of Common Stock by such Award holder will be made only  pursuant to (i) a
Registration  Statement  under the Securities Act which is effective and current
with  respect  to the  shares of Common  Stock  being  sold,  or (ii) a specific
exemption  from the  registration  requirements  of the  Securities  Act, but in
claiming  such  exemption,  the Award holder shall prior to any offer of sale or
sale of such shares of Common Stock provide the Company with a favorable written
opinion of counsel  satisfactory  to the Company,  in form,  substance and scope
satisfactory to the Company,  as to the  applicability  of such exemption to the
proposed sale or distribution.

                  In addition, if at any time the Committee shall determine,  in
its sole  discretion,  that the listing or qualification of the shares of Common
Stock subject to any Award or option on any securities exchange, Nasdaq or under
any  applicable  law, or the consent or approval of any  governmental  agency or
regulatory  body,  is necessary or desirable as a condition to, or in connection
with,  the  granting  of an Award or the  issuing  of  shares  of  Common  Stock
thereunder,  such  Award may not be  granted  and such  option or SAR may not be
exercised  in whole or in part unless such  listing,  qualification,  consent or
approval  shall  have been  effected  or  obtained  free of any  conditions  not
acceptable to the Committee.

                  10.  AWARD  CONTRACTS.  Each Award  shall be  evidenced  by an
appropriate  Contract  which shall be duly executed by the Company and the Award
holder, and shall contain such terms, provisions and conditions not inconsistent
herewith  as may be  determined  by the  Committee.  The terms of each Award and
Contract need not be identical.

                  11. ADJUSTMENTS UPON CHANGES IN COMMON STOCK.  Notwithstanding
any  other   provision  of  the  Plan,  in  the  event  of  a  stock   dividend,
recapitalization,  merger in which the  Company  is the  surviving  corporation,
spin-off, split-up,  combination or exchange of shares or the like which results
in a change in the number or kind of shares of Common Stock which is outstanding
immediately prior to such event, the aggregate number and kind of shares subject
to the Plan, the aggregate number and kind of shares subject to each outstanding
Award,  the  exercise  price of each  option,  the base  price of each SAR,  any
contingencies  and restrictions  based on the number or kind of shares,  and the
162(m) Maximum shall be appropriately adjusted by the Board of Directors,  whose
determination  shall be conclusive and binding on all parties.  Such  adjustment
may provide for the  elimination of fractional  shares which might  otherwise be
subject to Awards without payment therefor.

                  In the  event of (a) the  liquidation  or  dissolution  of the
Company, (b) a merger in which the Company is not the surviving corporation or a
consolidation,  or (c) any  transaction (or series of related  transactions)  in
which  (i) more  than 50% of the  outstanding  Common  Stock is  transferred  or
exchanged  for other  consideration  or (ii) shares of Common Stock in excess of
the number of shares of Common Stock outstanding





<PAGE>



immediately  preceding the  transaction are issued (other than to stockholder of
the  Company  with  respect  to  their  shares  of  stock  in the  Company,  any
outstanding options, SARs or unvested stock shall terminate upon the earliest of
any such event, unless other provision is made therefor in the transaction.

                  12.  AMENDMENTS  AND  TERMINATION  OF THE  PLAN.  The Plan was
adopted by the Board of Directors on April 10, 1997. No ISO may be granted under
the Plan after April 9, 2007. The Board of Directors,  without further  approval
of the Company's stockholders, may at any time suspend or terminate the Plan, in
whole or in part,  or amend it from time to time in such respects as it may deem
advisable,  including,  without limitation, in order that ISOs granted hereunder
meet the  requirements  for "incentive  stock options" under the Code, to comply
with the provisions of Rule 16b-3,  Section 162(m) of the Code, or any change in
applicable law,  regulations,  rulings or  interpretations  of any  governmental
agency  or  regulatory  body;  provided,  however,  that no  amendment  shall be
effective without the requisite prior or subsequent  stockholder  approval which
would (a) except as contemplated in Paragraph 11, increase the maximum number of
shares of Common  Stock for which  Awards may be  granted  under the Plan or the
162(m)  Maximum,  (b)  change the  eligibility  requirements  to receive  Awards
hereunder,  or (c) make any change for which applicable law, regulation,  ruling
or interpretation by the applicable  governmental agency or regulatory authority
requires stockholder  approval.  No termination,  suspension or amendment of the
Plan  shall  adversely  affect  the  rights of any Award  holder  under an Award
without his prior consent. The power of the Committee to construe and administer
any Awards granted under the Plan prior to the  termination or suspension of the
Plan  nevertheless   shall  continue  after  such  termination  or  during  such
suspension.

                  13.  NON-TRANSFERABILITY.  No option or SAR granted  under the
Plan shall be  transferable  otherwise  than by will or the laws of descent  and
distribution,  and options and SARs may be exercised, during the lifetime of the
Award holder, only by him or his Legal Representatives.  Except as may otherwise
be expressly provided in the Contract,  a stock Award, to the extent not vested,
shall not be  transferable  otherwise  than by will or the laws of  descent  and
distribution.  Except to the extent provided above,  Awards may not be assigned,
transferred,  pledged,  hypothecated  or  disposed  of in any  way  (whether  by
operation of law or otherwise) and shall not be subject to execution, attachment
or  similar  process,  and any  such  attempted  assignment,  transfer,  pledge,
hypothecation or disposition shall be null and void ab initio and of no force or
effect.

                  14. WITHHOLDING TAXES. The Company, a Subsidiary or Parent may
withhold  (a) cash or (b) with the  consent of the  Committee,  shares of Common
Stock to be  issued  under a stock  Award or upon  exercise  of an option or SAR
having an aggregate  Fair Market Value on the relevant date, or a combination of
cash and shares  having such value,  in an amount  equal to the amount which the
Committee  determines is necessary to satisfy the obligation of the Company, any
of its  Subsidiaries or a Parent to withhold  federal,  state and local taxes or
other amounts incurred by reason of the grant, vesting,  exercise or disposition
of an Award,  or the  disposition  of the  underlying  shares  of Common  Stock.
Alternatively,  the Company  may  require the holder to pay to the Company  such
amount, in cash, promptly upon demand.

                  15. LEGENDS; PAYMENT OF EXPENSES. The Company may endorse such
legend or legends upon the  certificates for shares of Common Stock issued under
a stock Award or upon  exercise of an option or SAR under the Plan and may issue
such  "stop  transfer"  instructions  to its  transfer  agent in respect of such
shares as it determines,  in its  discretion,  to be necessary or appropriate to
(a) prevent a violation of, or to perfect an exemption  from,  the  registration
requirements of the Securities Act and any applicable state securities laws, (b)
implement the  provisions  of the Plan or any agreement  between the Company and
the Award holder with respect to such shares of Common Stock,  or (c) permit the
Company to determine the occurrence of a





<PAGE>



"disqualifying  disposition," as described in Section 421(b) of the Code, of the
shares of Common Stock issued or transferred upon the exercise of an ISO granted
under the Plan.

                  The Company  shall pay all issuance  taxes with respect to the
issuance of shares of Common  Stock under a stock Award or upon the  exercise of
an  option or SAR  granted  under  the  Plan,  as well as all fees and  expenses
incurred by the Company in connection with such issuance.

                  16.  USE OF  PROCEEDS.  The cash  proceeds  received  upon the
exercise  of an option,  or grant of a stock Award under the Plan shall be added
to the general funds of the Company and used for such corporate  purposes as the
Board of Directors may determine.

                  17.   SUBSTITUTIONS  AND  ASSUMPTIONS  OF  AWARDS  OF  CERTAIN
CONSTITUENT CORPORATIONS. Anything in this Plan to the contrary notwithstanding,
the Board of  Directors  may,  without  further  approval  by the  stockholders,
substitute  new  Awards  for  prior  options,  SARs  or  restricted  stock  of a
Constituent Corporation (as defined in Paragraph 18) or assume the prior options
or restricted stock of such Constituent Corporation.

                  18. DEFINITIONS. For purposes of the Plan, the following terms
shall be defined as set forth below:

such corporation.

national securities exchange, the average of the highest and lowest sales prices
per share of  Common  Stock on such day as  reported  by such  exchange  or on a
composite tape reflecting  transactions on such exchange,  (ii) if the principal

<PAGE>



or no quotes are  available  for such day,  the Fair Market  Value of a share of

conflict of law provisions that would defer to the  substantive  laws of another
jurisdiction.

                  Neither  the  Plan nor any  Contract  shall  be  construed  or

approval by a majority of the votes  present in person or by proxy and  entitled
to vote hereon at the next duly held meeting of the  Company's  stockholders  at
which a quorum is present.  No Award granted  hereunder may vest or be exercised
prior to such approval;  provided,  however, that the date of grant of any Award
shall  be  determined  as if the Plan had not  been  subject  to such  approval.
Notwithstanding  the  foregoing,  if the Plan is not  approved  by a vote of the
stockholders  of the Company on or before April 9, 1998, the Plan and any Awards
granted hereunder shall terminate.


                                                                   Exhibit 10.22

         4. Draw Down Terms.  Subject to the  satisfaction of the conditions set
forth in Section 3 hereof, the parties agree as follows:



                                      - 2 -

<PAGE>



                  (a)  During the  Exercise  Period  (as  hereinafter  defined),
Xybernaut,  may, in its sole  discretion,  issue and exercise Draw Downs,  which
Draw Downs the Buyer will be obligated to accept.  The initial Draw Down may not
be initiated  before  Thursday,  October 8, 1998.  The next Draw Down shall only
occur after the end of the Draw Down  Pricing  Period for the initial  Draw Down
and successive  Draw Downs may only occur after the end of the Draw Down Pricing
Period for the immediately preceding Draw Down.

                  (b) Only one Draw  Down  shall be  allowed  in each  Draw Down
Pricing Period. The Settlement (as such is hereinafter defined) of the Draw Down
shall occur on the first  trading day following the end of the Draw Down Pricing
Period (the "Draw Down Exercise Date"),  based on the Average Daily Price during
the Draw Down Pricing Period.

                  (c) Subject to all restrictions being satisfied,  the exercise
of each  Draw  Down  will be  automatic  without  any  additional  action  being
required.  The  exercise of each Draw Down will be  "European  Style" ( i.e. the
Draw Down can be exercised only on the Draw Down Exercise Date).

                  (d) Each Draw Down will expire on the calendar day immediately
following the Draw Down Exercise Date.

                  (e) Xybernaut must inform Buyer via facsimile  transmission as
to the amount of the Draw Down  Xybernaut  wishes to exercise  before trading in
the Common Stock the first day of the Draw Down  Pricing  Period (the "Draw Down
Notice").  The closing bid price of the Common Stock on each Draw Down  Exercise
Date must be greater than $3.00 per share as reported by the relevant  market or
exchange.  At no time shall Buyer be required to purchase  more shares of Common
Stock than amount set forth in the Draw Down Notice.  For purposes  hereof,  the
term "Draw Down" shall mean Xybernaut's exercise of the right to commence a Draw
Down Pricing Period with respect to Buyer's  commitment to purchase Common Stock
pursuant to Section 2(a) hereof.

                  (f) On or before  three (3)  trading  days after the Draw Down
Exercise Date, Xybernaut shall deliver the Shares purchased by Buyer to Buyer or
to The Depositary  Trust Company ("DTC") on Buyer's behalf.  Xybernaut and Buyer
shall cause such Shares to be  credited to the DTC account  designated  by Buyer
upon  receipt  by  Xybernaut  of  payment  for the  Draw  Down  into an  account
designated by Xybernaut. The delivery of the shares of Common Stock into Buyer's
DTC account in  exchange  for  payment  therefor  shall be referred to herein as
"Settlement". Buyer shall coordinate with Xybernaut each Settlement through DTC.

         5.  Buyer's  Call  Option.  Buyer  shall have the right to  purchase an
additional  shares of Common  Stock in an amount equal to the amount of the Draw
Down as set forth in the Draw Down Notice (the  "Option").  For each  additional
amount that Buyer  exercises  the Option  pursuant to this Section 5, Buyer must
notify  Xybernaut in writing of such  exercise,  which exercise may be made on a
daily basis throughout the applicable Draw Down Pricing Period; provided that no
exercise  may be made later than 5:00 p.m.  (East coast time) on the last day of
the applicable Draw Down Pricing


                                      - 3 -

<PAGE>



Period.  If Buyer so exercises  its Option to purchase  additional  shares,  the
price for the shares of Common  Stock shall be the VWAP for the Common Stock for
each day during the applicable Draw Down Pricing Period that all or a portion of
the Option was  exercised.  If Buyer does not exercise its right to exercise the
Option by such time on the last day of the applicable  Draw Down Pricing Period,
Buyer's  right to exercise the Option with respect to the  applicable  Draw Down
Pricing Period shall terminate.

         6. Restrictions. The parties further agree as follows:

                  (a) Xybernaut  must remain listed or admitted for trading,  as
applicable,  on the NASDAQ  Small Cap Market  Systems,  NASDAQ  National  Market
Systems,  the New York Stock  Exchange or the  American  Stock  Exchange for the
entire Draw Down Pricing Period.

                  (b) Should there occur a Material  Adverse  Effect or Material
Change in  Ownership of Xybernaut  during any Draw Down  Pricing  Period,  Buyer
shall  not  be  required  to  accept  the  Draw  Down,  unless  Buyer  otherwise
determines, in sole and absolute discretion.

                  (c) All cash payable to  Xybernaut  upon the  Settlement  of a
Draw  Down or the  exercise  of an Option  shall be paid by Buyer to a  mutually
agreed upon escrow account  against the concurrent  delivery to the escrow agent
of the escrow  amount of the shares of Common Stock  subject to the Draw Down or
the exercise of the Option, as applicable.

                  (d) At all times during the term of this Agreement  there must
be a minimum of eight (8) active Market Makers for  Xybernaut's  Common Stock on
the NASDAQ Small Cap Market or NASDAQ National  Market  Systems,  as applicable,
unless  Xybernaut's Common Stock is listed on the New York Stock Exchange or the
American Stock Exchange.

                  (e) The  Settlement  of all Draw Downs shall take place on the
Draw Down Exercise Date.

         7. Registration Statement.  Promptly after the day of the Settlement of
the  second  Draw Down  hereunder,  Xybernaut  shall  cause to be filed with the
Securities and Exchange  Commission (the "Commission") a Registration  Statement
on Form S-3 (or any other  comparable form) to register for resale the shares of
Common Stock purchased by Buyer pursuant to this Agreement.  Xybernaut shall use
its best efforts to take all steps necessary to cause the Registration Statement
to be declared  effective  by the  Commission  as  reasonably  expeditiously  as
possible.

         8. Warrants; Fees, etc. The parties agree as follows:

                  (a)  For  each  Draw  Down,   Buyer  will   receive   warrants
("Warrants") to purchase 12,500 shares of Common Stock. Each Warrant will have a
three (3) year term from its date of issuance.  The Common Stock  underlying the
Warrants will be registered in the Registration Statement referred to in Section
7 hereof.



                                      - 4 -

<PAGE>



                  (b) The  Warrant  Strike  Price  shall be 225% of the  Average
Daily Price of the Common Stock on the date Xybernaut  furnishes  Buyer with the
applicable Draw Down Notice to which the Warrants relate.

                  (c) Settondown Capital International, Ltd. ("Settondown") will
receive a fee of six  percent  (6%) of the total  amount  paid for the shares of
Common Stock by Buyer in accordance with this Agreement.  Xybernaut acknowledges
that  Settondown  may use a  portion  of its  fee to  compensate  other  parties
relative to a particular Draw Down.

                  (d)  Notwithstanding  the foregoing,  should the  Registration
Statement not be filed with the Commission within thirty (30) days following the
day of the Settlement of the second Draw Down hereunder,  the fee due Settondown
shall be increased by one percent (1%) to seven percent (7%);  and therefore the
fee shall be increased  by an  additional  one percent (1%) for each  additional
thirty (30) days that the Registration Statement is not filed, if applicable.

                  (e) Xybernaut will be responsible for the payment of all costs
and  expenses  incurred  by  Buyer  or  Xybernaut  related  to the  transactions
contemplated by this Agreement.

         9. Representations, Warranties and Covenants of Buyer. Buyer represents
and  warrants to  Xybernaut,  and  covenants  for the benefit of  Xybernaut,  as
follows:

                  (a) This Agreement has been duly authorized,  validly executed
and  delivered  by Buyer and  constitutes  a valid  and  binding  agreement  and
obligation of Buyer  enforceable  against  Buyer in  accordance  with its terms,
subject  to  limitations  on  enforcement  by general  principles  of equity and
bankruptcy  or  other  laws  affecting  the  enforcement  of  creditors'  rights
generally;

                  (b) Buyer has received and  carefully  reviewed  copies of the
Public Documents (as hereinafter defined). No representations or warranties have

herein or as set forth in the other  documents  expressly  referred  to  herein.
Buyer understands that no federal,  state, local or foreign governmental body or
regulatory  authority  has made any  finding or  determination  relating  to the
fairness of an investment in the Securities and that no federal, state, local or
foreign  governmental body or regulatory  authority has recommended or endorsed,

representations made by third parties;

                  (c) Buyer  understands  that the  Securities are being offered

securities laws and that Xybernaut is relying upon the truth and accuracy of the

Buyer  set  forth  herein  for  purposes  of  qualifying  for  exemptions   from
registration under the Securities Act, and applicable state securities laws;

501 of Regulation D promulgated under the Securities Act;

                  (e) The Buyer (i) is and will be acquiring the  Securities for

the  Securities,  in whole or in part, in violation of the Securities Act or any
applicable  securities  laws  and  (ii)  has  not  offered  or  sold  any of the
Securities  and has no present  intention or agreement to divide the  Securities

exempt from registration under the Securities Act, by virtue of Section 4(2) and
Regulation D promulgated  under the Securities Act. Buyer  understands  that the
shares of Common Stock  purchased  hereunder  (the  "Shares")  and the shares of
Common Stock underlying the Warrants have not been, and may never be, registered
under the Securities Act; that the Shares cannot be sold, transferred, assigned,
pledged or  subjected  to any lien or  security  interest  unless they are first
registered  under the Securities Act and such state and other securities laws as

registration  under the  Securities Act is available (and then the Shares may be
sold, transferred, assigned, pledged or subjected to a lien or security interest
only in  compliance  with  such  exemption  and all  applicable  state and other
securities  laws);  and that  the  following  legends  will be  placed  upon the
certificate for the Shares:

                         "The Shares  represented by this  certificate

                         Act of  1933,  as  amended  (the  "Securities
                         Act"),  and may not be offered for sale, sold
                         or   otherwise   transferred,    pledged   or
                         subjected  to any lien or security  interest,
                         in the absence of an  effective  registration
                         statement  under  the  Securities  Act  or  a
                         written  opinion of counsel  for the  Company
                         that the  Shares  may be  offered  for  sale,
                         sold, transferred,  pledged or subjected to a
                         lien  or  security  interest  pursuant  to an
                         exemption  under the  Securities Act and such
                         state  and  other  securities  laws as may be

investment in the  Securities by virtue of its experience as an investor and its
knowledge,  experience, and sophistication in financial and business matters and
Buyer is capable of bearing the entire loss of its investment in the Securities.
