      issued  upon  exercise  by the  Company of Put  Options  in the  aggregate
      principal  amount of  $3,000,000.  The  number  of shares of Common  Stock
      indicated  to be  issuable  in  connection  with the  exercise of such Put
      Options  and  included  in the total  shares of Common  Stock  offered for
      resale hereby is an estimate and  represents  100% of the number of shares
      that would be issuable  upon the exercise of Put Options in the  aggregate
      principal amount of $3,000,000 at a price of $2.87 per share, which is 90%
      of  $3.18750,  the  closing  bid price of the Common  Stock as reported by
      NASDAQ on May 6, 1998.  Such number of shares is subject to adjustment and
      could be materially less than such estimated amount depending upon factors
      that cannot be  predicted  by the Company at this time,  including,  among
      others,  the future market price of the Common Stock. This presentation is
      not intended to  constitute a prediction  as to the future market price of
      the Common  Stock or as to the number of shares of Common  Stock  issuable
      upon  exercise  of  Put  Options  in the  aggregate  principal  amount  of
      $3,000,000.  See "Risk Factors -- Dilution; Impact of Sale of Common Stock

                               PROSPECTUS SUMMARY

           The following  summary is qualified in its entirety by, and should be
read in conjunction with, the more detailed information and financial statements
and notes  thereto  appearing  elsewhere  or  incorporated  by reference in this
Prospectus.

           To inform  investors of the  Company's  future plans and  objectives,
this Prospectus (and other reports and statements  issued by the Company and its
officers from time to time) contain certain statements  concerning the Company's
future  results,   future  performance,   intentions,   objectives,   plans  and
expectations that are or may be deemed to be  "forward-looking  statements." The
Company's  ability  to do this  has  been  fostered  by the  Private  Securities
Litigation Reform Act of 1995 (the "Reform Act"), which provides a "safe harbor"
for  forward-looking  statements to encourage  companies to provide  prospective
information so long as those statements are accompanied by meaningful cautionary
statements  identifying  important  factors that could cause  actual  results to
differ materially from those discussed in the statement. The Company believes it
is in the best  interest of  investors to take  advantage  of the "safe  harbor"
provisions of the Reform Act. 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  and those  described in "Risk  Factors" could
cause the Company's  actual  results,  performance  and  achievements  to differ
materially from those described or implied in the forward-looking statements.

                                  RISK FACTORS

           An investment in the shares of Common Stock offered hereby involves a
high  degree  of risk.  Prospective  investors  should  carefully  consider  the
following risk factors,  in addition to the other  information set forth in this
Prospectus,  in  connection  with an  investment  in the shares of Common  Stock
offered hereby.

HISTORY AND EXPECTATION OF FUTURE LOSSES; NEED FOR ADDITIONAL FINANCING

           The Company was incorporated in October 1990 and commenced operations
in November 1992. In the fiscal years ended March 31, 1994 and 1995, the Company
incurred a net loss of $47,352 and $1,303,892,  respectively. In the years ended
December 31, 1996 and 1997,  the Company  incurred a net loss of $5,238,536  and
$9,479,966,  respectively.  The Company expects to incur a substantial  loss for
the quarter ended March 31, 1998. The consolidated balance sheets as of December
31,  1997  and 1996  and the  related  consolidated  statements  of  operations,
stockholders'  equity, and cash flows for the years then ended,  incorporated by
reference in this Prospectus,  have been incorporated  herein in reliance on the
report dated March 31, 1998, which includes an explanatory paragraph, concerning
the  Company's  ability to  continue  as a going  concern,  of Coopers & Lybrand
L.L.P.,  independent  accountants,  given  on  their  authority  as  experts  in
accounting and auditing.  The Company intends to conduct significant  additional
research, development and testing that, together with establishment of marketing
and distribution  capabilities,  are expected to require substantial funding and
to result in continuing  operating  losses until such time as  sufficient  gross
margins from revenues are generated to cover  operating  costs.  There can be no
assurance that, notwithstanding these efforts and the expenditure of substantial
funds, the Company ever will achieve substantial sales of any of its products or
profitable operations or that it will be able to meet the competitive demands of
the industry in which it  operates.  The success of the Company will be affected
by expenses,  operational  difficulties and other factors frequently encountered
in the development of a business enterprise in a competitive  environment,  many
of which may be beyond the Company's control.
See "Risk Factors - Competition."

LIQUIDITY; WORKING CAPITAL NEEDS

           To meet working capital cash requirements, the Company intends obtain
a working capital line of credit and/or complete additional financings including
the exercise of its Put Option under the Private Placement.  However,  there can
be no assurance that the Company can or will obtain sufficient funds to meet, in
whole or in part, its working  capital needs from  collections of product sales.
There can be no assurance that the Company will be capable of raising additional
capital thereafter or of establishing and obtaining funds from a working capital
line of credit,  or that the terms  upon  which  such  capital or line of credit
would be available to the Company would be acceptable, in which case the Company
could be required to curtail materially, suspend or cease operations.

DILUTION; IMPACT OF SALE OF COMMON STOCK UPON CONVERSION OF SERIES A
AND SERIES B PREFERRED STOCK, AND THE EXERCISE OF THE PUT OPTIONS AND WARRANTS

           The purchasers of the Shares offered hereby will experience immediate
and substantial  dilution in the net tangible value of their Shares in the event
of  conversion of  outstanding  Series A and Series B Preferred  Stock,  and the
exercise of the Put Options and Warrants.  Specifically, the Series A and Series
B Preferred Stock are convertible into Common Stock and the Company may exercise
the Put Options  resulting in the  issuance of Common  Stock at  discounts  from
future  market  prices of the Common  Stock,  which could result in  substantial
dilution  to existing  holders of Common  Stock.  The sale of such Common  Stock
acquired at a discount could have


                                       -4-

<PAGE>



a negative  impact on the trading  price of the Common Stock and could  increase
the volatility in the trading price of the Common Stock.

           In addition,  the Company has agreed to reserve and keep available at
all times, free of preemptive rights,  shares of Common Stock for the purpose of
enabling  the Company to satisfy  any  obligation  to issue the Put Shares,  the
Warrant A Shares and the Warrant B Shares; such amount of shares of Common Stock
to be  reserved  shall be  calculated  based  upon the  minimum  purchase  price
therefor under the terms of the Private Equity Line of Credit Agreement, Warrant
A and Warrant B. The Put Options are exercisable  into Common Stock at discounts
from future  market prices of the Common  Stock,  and shares issued  pursuant to
Warrant A and Warrant B may be issued at a discount to the future  market  price
of the Common  Stock,  which 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.  See
"Description of Securities."

SERIES A PREFERRED STOCK

           In June 1997, the Company sold 3,000 shares of the Series A Preferred
Stock,  each  share  with a  liquidation  preference  of $1,000  (the  "Series A
Liquidation Preference"), for an aggregate of $3 million. The Series A Preferred
Stock is convertible into Common Stock at discounts from future market prices of
the Common Stock, which could result in substantial dilution to existing holders
of  Common  Stock.  The  Company  must  reserve  and keep  available  out of its
authorized  but  unissued  shares of Common  Stock,  solely  for the  purpose of
effecting the conversion of the Series A Preferred  Stock,  at least such number
of its  Common  Stock  that  is  sufficient  to  effect  the  conversion  of all
outstanding  shares  of  the  Series  A  Preferred  Stock.  The  sale  or  other
disposition (for cash, shares of stock,  securities or other consideration),  of
all or substantially  all of the assets of the Company would entitle the holders
of the Series A Preferred  Stock to receive the Series A Liquidation  Preference
on all  their  shares  of Series A  Preferred  Stock  plus  accrued  and  unpaid
dividends.  The Company has  registered  a total of  1,960,713  shares of Common
Stock underlying the Series A Preferred  Stock, of which,  1,285,713 shares were
registered in a  registration  statement  filed with the Commission on September
22, 1997 and an  additional  675,000  shares were  registered in an amendment to
such registration  statement filed with the Commission on May 8, 1998. As of May
8,  1998,  1,503,217  shares  of  Common  Stock  had  been  issued  pursuant  to
conversions  of Series A Preferred  Stock.  See  "Description  of  Securities --
Series A Preferred Stock."

SERIES B PREFERRED STOCK

           In November 1997 and January 1998, the Company placed 4,000 shares of
the Series B Preferred Stock, each share with a liquidation preference of $1,000
(the "Series B Liquidation Preference"), for an aggregate of $4,000,000 and paid
the  placement  agent for this sale with 180  shares of the  Series B  Preferred
Stock.  In February  1998, the Company placed 1,000 shares of Series B Preferred
Stock and paid the  placement for this sale with 60 shares of Series B Preferred
Stock.  The  Series  B  Preferred  Stock is  convertible  into  Common  Stock at
discounts  from future market prices of the Common Stock,  which could result in
substantial  dilution  to existing  holders of Common  Stock.  The Company  must
reserve and keep available out of its  authorized but unissued  shares of Common
Stock,  solely  for the  purpose of  effecting  the  conversion  of the Series B
Preferred  Stock, at least such number of its Common Stock that is sufficient to
effect the conversion of all outstanding shares of the Series B Preferred Stock.
The sale or other  disposition (for cash,  shares of stock,  securities or other
consideration),  of all or substantially  all of the assets of the Company would
entitle  the  holders of the Series B  Preferred  Stock to receive  the Series B
Liquidation  Preference  on all their  shares of Series B  Preferred  Stock plus
accrued and unpaid  dividends.  The Company has  registered a total of 3,327,663
shares of Common Stock


                                       -5-

underlying the Series B Preferred Stock, of which,  2,622,663 were registered in
a  registration  statement  filed  with the  Commission  on  January 2, 1998 and
amended on January 22, 1998, and 705,000 were registered in a further  amendment
to such  registration  statement filed with the Commission on May 8, 1998. As of
May 8,  1998,  3,172,239  shares of Common  Stock had been  issued  pursuant  to
conversions  of Series B Preferred  Stock.  See  "Description  of  Securities --
Series B Preferred Stock."

UNCERTAINTY OF MARKET DEVELOPMENT AND PRODUCT ACCEPTANCE

           The mobile computing  market is emerging and relatively  undeveloped.
The Company  sold its first Mobile  Assistant(R)  in 1993 and as of December 31,
1997 had sold and delivered  approximately  $1.8 million of Mobile  Assistant(R)
systems.  The Company  commenced  delivery of the  Pentium(R)  Mobile  Assistant
P-133(TM) in August 1997 and has announced that it expects to commence  delivery
of Mobile  Assistant(R)  IV, a Pentium 266 MHz based  system  ("MA IV"),  in the
quarter  ending  December 31, 1998.  In September  1997,  the Company  announced
linkAssist(TM), a software development toolkit, which provides speech linking of
data in almost any format,  without altering the original data and webAssist(TM)
software  that allows voice  navigation  of HTML links found on the Internet and
intranet.  The size of the mobile computing  market is currently  limited by the
high unit prices of mobile  computers as compared to laptops and other  portable
computers,  the specialized  nature of each  application and the need for custom
applications and system integration and the limited supply to date of components
for completed  systems.  The potential size of the market will be limited by the
rate at which  prospective  customers  recognize  and accept the  functions  and
capabilities of integrated mobile computing  systems.  There can be no assurance
that a  significant  market will develop for mobile  computing  systems or, if a
market develops,  that the Mobile  Assistant(R)  series and any of the Company's
other products will become a significant factor in any market that develops.  In
addition, there is no assurance that the Company will obtain the working capital
needed to meet the competitive demands of the industry in which it operates. See
"Risk Factors - Liquidity; Working Capital Needs; -- Competition."

           The   commercial   success   of  the  Mobile   Assistant(R)   series,
linkAssist(TM),  webAssist(TM)  and software  toolkits  enabling  the  Company's
customers  to  more  rapidly  create  customized  software   applications  on  a
stand-alone basis or for use with the Mobile Assistant(R)  series, and any other
product  that the  Company  may  develop  will  depend  upon  acceptance  by the
commercial, healthcare, education and military markets, of which there can be no
assurance.

           The   Company   believes   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 the Company's other  products,  of which
there can be no assurance.

COMPETITION

           The computer  industry is intensely  competitive and is characterized
by rapid technological  advances,  evolving industry standards and technological
obsolescence.  Many of the Company's  current  competitors have longer operating
histories and greater financial, technical, sales, marketing and other resources
than the Company.  Several other  companies are engaged in the  manufacture  and
development of body-mounted or hand-held computing systems that compete with the
Mobile  Assistant(R)  series,  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.  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


                                       -6-

<PAGE>



are  manufactured  by major domestic and foreign  computer  manufacturers  which
possess  far more  resources  than the  Company  and can be  expected to compete
vigorously  with the Company for the market at which the Mobile  Assistant(R) is
directed.  In addition,  new and competing  technologies  are being developed in
hands-free mobile computing systems.  There can be no assurance that the Company
will be able to compete successfully against its competitors,  that it will have
the working capital needed to incorporate the constant technological advances in
its  products or that the  competitive  pressures  faced by the Company will not
adversely affect its financial performance.

DEPENDENCE UPON SUPPLIERS

           To prepare the Mobile  Assistant(R)  P-133 for delivery to customers,
the Company purchases system components from several suppliers, who manufacture,
assemble,  integrate and test these components.  The Company then combines those
components and performs system tests prior to shipping.  Certain  components are
currently  purchased from single  suppliers.  The Company expects that the MA IV
will be assembled, integrated and tested by third party. The Company has entered
into written agreements with its suppliers for batteries,  head-mounted displays
and computing  units.  Although the Company  believes there are multiple sources
for many parts and  components,  the Company  currently  depends  heavily on its
current suppliers.  Although management believes that the Company 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 the
Company 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,  the Company also could experience
delays or interruptions in supply in the event the Company is required to find a
new supplier for any of these components. Any disruptions in supply of necessary
parts and  components  from the Company's  key  suppliers  could have a material
adverse effect on the Company's  results of operations.  Any future  shortage or
limited  allocation  of  components  for the  Mobile  Assistant(R)  could have a
material adverse effect on the Company.

SUBSTANTIAL DEPENDENCE UPON SINGLE PRODUCT LINE;
POSSIBILITY OF UNSUCCESSFUL NEW PRODUCT DEVELOPMENT

           The Mobile  Assistant(R) series currently consists of the P-133 model
based on a 133 MHz Intel  Pentium(R)  processor and the MA IV, which is expected
to be available in late 1998. The Mobile  Assistant(R)  series are the Company's
principal products,  and its success will depend upon its commercial acceptance,
which  cannot be assured.  For single unit  purchases,  the Mobile  Assistant(R)
P-133  currently  is priced  from  $7,196 to $8,995 and up,  depending  upon the
discount and selected features. As technological  developments cause declines in
hardware costs, the Company expects that mobile computer sales will be driven by
system  capabilities  and  integration.  There is no  assurance  that the Mobile
Assistant(R) will offer the performance  capabilities or features that customers
will value and, if not,  the  Company  could be required to modify the design of
the Mobile  Assistant(R) which may require the expenditure of additional capital
currently  unavailable to the Company.  While  linkAssist(TM)  and the Company's
planned software toolkits are intended for use both with the Mobile Assistant(R)
series and  independently,  there can be no assurance that a separate market for
the Company's existing and planned software products will develop.  There can be
no assurance that any products,  if sold, will generate  significant revenues or
any profits.  The Company is also developing  additional products for the Mobile
Assistant(R)  series for  introduction  in the future and  intends to modify the
Mobile  Assistant(R)  series for use in other  applications and to develop other
products using its core technologies. Additional product development will result
in the Company incurring  significant research and development expenses that may
be unrecoverable  should  commercialization  of new products prove unsuccessful.
The Company also could require additional funding if research and


                                       -7-

<PAGE>



development  expenses  are greater than  anticipated.  There can be no assurance
that the Company will be successful in its future product development efforts or
in diversifying its product line. See "Risk Factors - Liquidity; Working Capital
Needs."

UNCERTAIN PROTECTION OF PATENT AND PROPRIETARY RIGHTS;
NO ASSURANCE OF ENFORCEABILITY OR SIGNIFICANT COMPETITIVE ADVANTAGE

           The  Company   considers  its  patent,   trade  secrets,   and  other
intellectual  property  and  proprietary  information  to be  important  to  its
business prospects. The Company relies on a combination of patent, trade secret,
copyright  and  trademark  laws and  contractual  restrictions  to establish and
protect its proprietary rights. The Company has entered into confidentiality and
invention   assignment   agreements   with  its   employees,   and  enters  into
non-disclosure  agreements  with  its  suppliers,  VARs,  OEMs  and  actual  and
potential  customers  to  limit  access  to and  disclosure  of its  proprietary
information. The Company has registered its Mobile Assistant(R) and Xybernaut(R)
trademarks on the  Principal  Register of the United States Patent and Trademark
Office ("Patent Office").

           In  April  1994,   U.S.   patent   number   5,305,244   ("hands-free,
user-supported  portable  computers") (the "Patent") for the Mobile Assistant(R)
Series was granted to the Company.  This patent was  previously  assigned to the
Company by several  employees of the Company.  In  September  1995,  the Company
received  a  notification  from the Patent  Office  entitled  "office  action in
reexamination,"  which  indicated  that  certain  claims  under the Patent  were
subject to reexamination and were preliminarily  rejected.  The reexamination of
the  Patent was  initiated  as a result of a request  from one of the  Company's
competitors.  In May 1996, the Company was successful in the  reexamination  and
the Patent Office issued a Notice of Intent to Issue  Reexamination  Certificate
and  Reexamination  Reasons for  Patentability/Confirmation  with respect to the
issues raised by the request for  reexamination,  wherein it concluded  that the
Company's claims are patentable with respect to the issues raised by the request
for  reexamination.  In April 1996,  the Company  received  notification  that a
second  reexamination  request had been filed with the Patent Office by the same
competitor that had initiated the prior reexamination, and in September 1996 the
Company  received a notification  from the Patent Office entitled "office action
in  reexamination,"  which  indicates  that certain claims under the patent were
subject to reexamination and were preliminarily  rejected. In November 1996, the
Company  filed  a  written  response  to  the  request  for   reexamination  and
preliminary  rejection.  The second  re-examination  has been  concluded and the
Patent Office indicated that the Company was successful in the reexamination and
sent the  Company  a  "Notice  of  Intent  to Issue  Reexamination  Certificate"
indicating that the Patent Office ruled in the Company's favor.  Subsequently on
September 23, 1997,  the Patent Office issued the  Reexamination  Certificate to
the  Company  indicating  successful  results  for  the  Company  in the  second
re-examination.  Most of the  Company's  revenue  for the  twelve  months  ended
December 31, 1997 and 1996 were derived from products  included within the scope
of the patent.  The  Company  has  notified  several of its  competitors  of the
existence  of the Patent,  which the  Company's  counsel  believes may have been
infringed by some of such  competitors.  The Company intends to take any and all
appropriate measures,  including legal action, necessary to maintain and enforce
its rights  under the Patent and to recover any damages  suffered as a result of
any alleged infringement.

           Since July 1996,  the Company has filed fifteen  patent  applications
covering  various  aspects of  computers  in general and  wearable  computers in
particular.  Of these fifteen  applications,  five additional  patents have been
issued,  one patent has been  allowed  pending  issuance  and nine  patents  are
pending.  Most of these applications have also been filed in European countries,
The  People's  Republic of China,  Japan,  Republic of Korea,  Republic of China
(Taiwan),  Canada and Australia. All patents obtained by Company employees under
pending  and future  applications  have been and will be assigned to the Company
under existing invention assignments.

<PAGE>



           Notwithstanding  the  foregoing,  there can be no assurance  that the
Company's  pending patent  applications  will issue as patents,  that any issued
patent will provide the Company with significant  competitive advantages or that
challenges will not be instituted  against the validity or enforceability of any
patent held by the Company.  The cost of  litigation  to uphold the validity and
prevent  infringement  of  patents  can be  substantial.  There  also  can be no
assurance that others will not  independently  develop  similar or more advanced
products,  design patentable alternatives to the Company's products or duplicate
the Company's trade secrets. The Company may in some cases be required to obtain
licenses  from  third-parties  or to redesign its products or processes to avoid
infringement.   The  Company  also  relies  on  trade  secrets  and  proprietary
technology  and enters into  confidentiality  agreements  with its employees and
consultants.  There can be no  assurance  that the  obligation  to maintain  the
confidentiality  of such trade secrets or  proprietary  information  will not be
breached by employees or  consultants  or that the  Company's  trade  secrets or
proprietary  technology  will not  otherwise  become  known or be  independently
developed  by  competitors  in such a manner that the  Company has no  practical
recourse.

LIMITED MARKETING AND DIRECT SALES EXPERIENCE;
DEPENDENCE ON OTHERS FOR MARKETING AND SALES.

           The Company intends to continue  development of a sales  organization
to market  and sell its  mobile  computing  products  to  value-added  resellers
("VARs"), original equipment manufacturers ("OEMs"), distributors and end users.
The  Company is also  developing  a network of VARs,  distributors  and OEMs and
intends  to enter into  joint  ventures  and  licensing  or other  collaborative
arrangements to market and sell its mobile computing products. Such arrangements
may result in a loss of control by the Company  over the  marketing  and sale of
its products.  There can be no assurance  that the Company will be successful in
entering into such additional  arrangements or be able effectively to manage and
maintain its relationships  with others, or that any marketing and sales efforts
undertaken  for the  Company by others  will be  successful.  The  Company  also
markets  its  products  outside  of the  United  States.  A number  of risks are
inherent in international  transactions,  such as the imposition of governmental
controls  including  restrictions on the exporting of currency,  fluctuations in
foreign  currency  exchange rates,  export license  requirements,  political and
economic  instability,  trade restrictions,  changes in tariffs and difficulties
and  expenses  in managing  international  operations.  These and other  factors
beyond the  Company's  control may  adversely  affect the  Company's  ability to
achieve significant sales.

DEPENDENCE UPON AND NEED FOR KEY PERSONNEL; LIMITED MANAGEMENT TEAM

           The Company's  success  depends to a significant  extent on Edward G.
Newman,  its  President,  Chief  Executive  Officer and Chairman of its Board of
Directors.  The loss of Mr. Newman would have a material  adverse  effect on the
Company's  progress and ultimate  likelihood of success.  Because the Company is
substantially  dependent on Mr.  Newman's  services and there are currently only
two other board-elected  officers of the Company,  the Company may be considered
to have limited  management.  Although the Company has entered into a three-year
employment  agreement with Mr. Newman, this agreement may not assure the Company
the continued services of Mr. Newman. The Company has obtained a key-person life
insurance  policy on the life of Mr.  Newman in the  amount of  $2,000,000.  The
Company's success also will depend upon its ability to attract and retain highly
qualified and experienced management and technical personnel.  The Company faces
competition for such personnel from numerous other entities,  many of which have
significantly greater resources than the Company. There can be no assurance that
the  Company  will be  successful  in  recruiting  such  personnel  or that,  if
recruited,  such persons would succeed in establishing profitable operations for
the Company.

CUSTOMER CONCENTRATION

           For the twelve  month period  ended  December  31,  1996,  two of the
Company's  customers accounted for 64% and 24%,  respectively,  of the Company's
revenues.  For the fiscal year ended December 30, 1997, two customers  accounted
for 34% and  10%,  respectively  of the  Company's  revenues.  Accordingly,  the
Company is significantly  dependent on revenues derived from a limited number of
customers.  The loss of one or more  significant  customers  may have a material
adverse  effect on the ability of the Company to achieve  profitability.  To the
extent the Company's  dependence  increases on large corporate  customers in the
future,  the Company will be subject to an  increased  risk that the loss of any
such customers will have a material  adverse effect on the Company's  results of
operations.  The Company may remain  dependent  in the  immediate  future upon a
limited number of customers (the identity of which may be subject to change) for
a material percentage of its annual operating revenue.

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  standards  could render the Company's  existing  products and products
currently under  development  obsolete and  unmarketable.  The Company's success
will depend upon its  ability to enhance  its current  products  and develop and
successfully  introduce and sell new products that keep pace with  technological
developments and respond to evolving end user  requirements.  Any failure by the
Company to anticipate or respond adequately to technological developments or end
user  requirements,   or  any  significant  delays  in  product  development  or
introduction, could damage the Company's competitive position in the marketplace
and reduce  revenues.  The  Company  expects to increase  the use of  additional
external and internal resources in the near term to meet these challenges. There
can be no assurance that the Company will be successful in hiring,  training and
retaining qualified product  development  personnel to meet its needs. There can
be no assurance  that the Company 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 the Company's results of operations.

YEAR 2000 ISSUES

            The Company is aware of the  computing  issues  associated  with the
coming of the millennium (year 2000), most notably whether computer systems will
properly  recognize  date sensitive  information  when the year changes to 2000.
Systems that do not properly recognize such information could generate erroneous
data or cause a system  to fail.  Based on  preliminary  investigations  and the
representations of several of its suppliers, the Company currently believes that
computers and software used in its  operations  and sold by the Company are year
2000  compliant.  The Company is working  with its  suppliers  and  customers to
either verify year 2000 compliance or identify and execute  appropriate  changes
to make such systems year 2000 compliant.  The Company believes that the cost of
completing  any  modifications  for year 2000  compliance to the systems used or
sold by the Company  will not be  material.  However,  there can be no assurance
that the  Company's  suppliers  will be correct in their  assertions  that their
products are year 2000  compliant or that the Company's  estimate of the cost of
systems  modifications  for year 2000  compliance  will prove  ultimately  to be
correct.

INDUSTRY CYCLICALITY

           The  computer  industry  historically  has been  affected by periodic
downturns,  which  have had an  adverse  economic  effect  on  manufacturers  of
computer  hardware  and  software  as well as upon end  users of  computers.  In
addition, the life cycle of existing computer products and timing of new product
development  and  introduction  can affect  demand for  computer  products.  The
Company's  results of  operations  for any  particular  period may be  adversely
affected by numerous  factors,  such as the loss of key  suppliers or customers,
price competition,  problems encountered in managing inventories or receivables,
the timing or  cancellation  of purchase orders with suppliers and the timing of
expenditures in anticipation  of increased sales and customer  product  delivery
requirements,  if any. Price  competition in the computer  industry in which the
Company  competes is intense and could  result in gross  margin  declines  which
could have an adverse impact on the Company's financial performance.

EFFECT OF POSSIBLE NON-CASH FUTURE CHARGE

           As a condition to the Company's  initial public offering (the "IPO"),
certain of the Company's  stockholders,  primarily officers and directors,  have
been  required to deposit an aggregate of 1,800,000  shares of Common Stock into
an escrow account (the "Escrowed  Shares").  The Escrowed  Shares are subject to
incremental  release  over a three-year  period only in the event the  Company's
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.  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 the price described below),  the Escrowed Shares will be returned
to the Company in amounts which have been agreed upon between the Representative
and the Company for each period and canceled. In addition to the foregoing,  all
the then  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. In
the event any Escrowed  Shares held by officers,  employees and  consultants are
released, the difference between the initial offering price and the market value
of  such  shares  at the  time  of  release  will  be  deemed  to be  additional
compensation expense to the Company. Assuming the price of Common Stock is equal
to or greater than the initial offering price of the shares at the Company's IPO
(of which there can be no assurance),  the release of the Escrowed  Shares would
result  in an  earnings  charge  that  would  have the  effect  of  reducing  or
eliminating  any  earnings  per share and could  have a  negative  effect on the
market price for the Common  Stock.  The  earnings per share target  calculation
will be based on the average number of shares issued and outstanding during each
period but excludes  shares issued  pursuant to a unit purchase  option  granted
pursuant to the IPO,  extraordinary items or compensation expense charged to the
Company  related to the release of the Escrowed  Shares.  The stock and earnings
targets for escrow  release for September 30, 1997 were not achieved and 300,000
shares were canceled from the escrow pool, which resulted in a reduction of 2.1%
of the Company's outstanding shares of Common Stock. Given the expected start of
full-scale  production of the MA IV in the quarter ending December 31, 1998, the
Company's  management  believes  that it is  likely  that  the  Company's  gross
revenues  and  allowable  losses will not meet the  Performance  Targets for the
12-month  period  ending  September  30, 1998.  Accordingly,  the release of the
escrow  shares  for this  period is only  likely if the  stock  price  equals or
exceeds  $11.00  for 25  consecutive  trading  days or 30 out of 35  consecutive
trading days prior to September 30, 1998. If conditions  are not met for release
from  escrow,  then  750,000  shares of stock will be returned to the Company on
September  30,  1998  and  canceled,  resulting  in  no  earnings  impact  and a
commensurately lower number of outstanding shares.

CONTROL BY EXISTING STOCKHOLDERS

           Following this offering, the Company's executive officers,  directors
and  principal   stockholders   will,  in  the   aggregate,   beneficially   own
approximately  31.2% of the Company's  outstanding shares of Common Stock. These
stockholders,  if acting  together,  will be able  effectively  to control  most
matters  requiring  approval by the  stockholders of the Company,  including the
election of  directors.  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

           The Company's Certificate of Incorporation provides that directors of
the Company shall not be personally  liable for monetary  damages to the Company
or its  stockholders  for a breach of fiduciary  duty as a director,  subject to
limited  exceptions.  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 directors of the Company.  See  "Indemnification for
Securities Act Liabilities."

SHARES ELIGIBLE FOR FUTURE SALE

           Sales of a substantial number of shares of the Company's Common Stock
in the public market  following this offering could adversely  affect the market
price of the Common Stock. Of the 21,736,680 shares of Common Stock that will be
outstanding or registered  for sale upon the  completion of this  offering,  the
3,846,429  shares  distributed in the IPO, the 4,675,456  shares of Common Stock
issued in connection  with the conversion of Series A Preferred Stock and Series
B Preferred  Stock,  the 457,496  unissued shares of Common Stock  registered in
connection  with the Series A Preferred  Stock,  the 155,424  unissued shares of
Common Stock  registered in connection with the Series B Preferred Stock and the
2,340,938  additional shares of Common Stock registered in this offering will be
freely  tradeable.  The  remaining  10,260,937  shares of the  Common  Stock are
"restricted  securities" as that term is defined in Rule 144  promulgated  under
the Securities  Act, and in the future may only 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 Rule 144 commencing 90
days from the date of this  Prospectus and at various times  thereafter  through
November  1997.  However,  pursuant  to the  terms of  agreements  entered  into
pursuant to the IPO,  the holders of  9,905,437  shares of Common  Stock may not
sell or dispose of their  shares of Common  Stock  until July 18,  1998  without
prior written consent of the  representative  of the underwriter in the IPO (the
"Representative").

SECURITIES ISSUABLE PURSUANT TO OPTIONS, WARRANTS AND THE UNIT PURCHASE OPTION

           At the date of this Prospectus, the Company has reserved an aggregate
of  6,546,692  shares of Common  Stock for  issuance on exercise of  outstanding
options and warrants.  The exercise prices of the options presently  outstanding
are $0.01 per share for 100,000 shares  granted in September  1994, and $1.37 to
$6.00 for  1,290,430  shares  granted  from  April 1, 1995 to May 8,  1998.  The
exercise price of the 287,860 warrants  outstanding as of May 8, 1998 is between
$1.76 and $18.00 per share.  In connection  with the Company's IPO,  warrants to
purchase  3,846,429  shares were  originally  issued that  entitle the holder to
purchase a share of common stock for $9.00 until July 19, 1999.  These  warrants
contain  anti-dilution  provisions that have resulted in the number of shares to
be issued upon a complete  warrant  exercise  increasing  to  4,583,402.  At the
completion of the IPO, the Representative received an option (the "Unit Purchase
Option") to purchase 210,000 Units (the "Units"), each


                                      -12-

<PAGE>



unit  consisting  of one share of Common  Stock and one  Redeemable  Warrant  (a
"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, 1997. The Warrants included in
the Unit Purchase Option are  exercisable at $12.60 per share.  During the terms
of the outstanding  options,  warrants and the Unit Purchase Option, the holders
are  given the  opportunity  to profit  from a rise in the  market  price of the
Common Stock,  and their exercise may dilute the ownership  interest of existing
stockholders,  including  investors  in  this  offering.  The  existence  of the
options,  the warrants and the Unit  Purchase  Option may  adversely  affect the
terms on which the Company may obtain additional equity financing. Moreover, the
holders are likely to exercise  their  rights to acquire  Common Stock at a time
when the  Company  would  otherwise  be able to  obtain  capital  on terms  more
favorable than could be obtained through the exercise of such securities.

NO DIVIDENDS ANTICIPATED

           The Company has never paid any dividends on its  securities  and does
not anticipate the payment of dividends in the foreseeable future.

VOLATILITY OF STOCK PRICE

           The trading price of the Common Stock has been  volatile,  and it may
continue to be so. Such trading price could be subject to wide  fluctuations  in
response to announcements of business and technical  developments by the Company
or its competitors,  quarterly variations in operating results, and other events
or factors,  including expectations by investors and securities analysts and the
Company's prospects.  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 the Common Stock.

ANTI-TAKEOVER CONSIDERATION; RIGHTS OF PREFERRED STOCK

           The Company's 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 A Preferred Stock
and the Series B 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 of the  Company.  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  management of the Company.
The Company has no present  intention to issue any additional  Preferred  Stock.
See "Description of Securities -- Preferred Stock."

           In addition,  the Board of Directors of the Company  recently adopted
resolutions which implemented a classified or staggered Board of Directors which
would  limit an  outsider's  ability to effect a rapid  change of control of the
Board.

           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 of the Company without any
further action by the  shareholders.  In addition,  issuance of Preferred Stock,
without shareholder approval,


                                      -13-

<PAGE>



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."


                                 USE OF PROCEEDS

           The Shares being offered hereby are being  registered for the account
of the Selling Stockholders,  and, accordingly, the Company will not receive any
of the proceeds from the sale of the Shares.


                              SELLING STOCKHOLDERS

           The Shares being offered for resale by the Selling  Stockholders were
acquired in  connection  with the April 1998 Private  Placement  and the January
1998  Private  Placement.  Pursuant to the terms and  conditions  of the Private
Equity  Line of Credit  Agreement,  certain  of the  Selling  Stockholders  will
purchase up to an additional  $10,000,000  of the Company's  Common Stock during
the  Commitment  Period,  as  defined  in the  agreement.  See  "Description  of
Securities."

           The  following  table sets forth  certain  information  regarding the
ownership  of shares of Common  Stock by the Selling  Stockholders  as of May 8,
1998, and as adjusted to reflect the sale of the Shares.  The information in the
table  concerning the Selling  Stockholders  who may offer Shares hereunder from
time  to  time  is  based  on  information  provided  to  the  Company  by  such
stockholder,  except for the assumed  exercise of the Warrant A and Warrant B by
the holders thereof and the exercise by the Company of the Put Option,  which is
based solely on the assumptions  referenced in footnotes (1), (2) and (3) to the
table.  Information  concerning the Selling Stockholders may change from time to
time and any  changes of which the  Company  is  advised  will be set forth in a
Prospectus Supplement to the extent required. See "Plan of Distribution."

                            DESCRIPTION OF SECURITIES

GENERAL

           The  authorized  capital stock of the Company  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,  19,622,946
shares of Common  Stock  are  issued  and  outstanding,  750  shares of Series A
Preferred  Stock are issued and  outstanding and no shares of Series B Preferred
Stock are issued and outstanding.  The Company currently has reserved  6,546,692
shares  of  Common  Stock for  issuance  pursuant  to  outstanding  options  and
warrants.

THE PRIVATE PLACEMENT

           On April 13, 1998 (the "Subscription  Date"), the Company consummated
a Private  Placement  which  contemplates  the sale of up to  $11,000,000 of the
Company's  Common Stock over a period of up to two years from the effective date
of  the  Registration  Statement  of  which  this  Prospectus  is  a  part  (the
"Commitment Period").

           Pursuant to the terms of a Private  Equity  Line of Credit  Agreement
(the   "Agreement"),   Balmore  Funds  S.A.  and  Austost  Anstalt  Schaan  (the
"Investors")  purchased  Common Stock in the principal amount of $1,000,000 (the
"Initial Shares") at an initial purchase price of $1.2656 per share. The Company
also  issued  to each  Investor  a Warrant  A and a  Warrant  B to  purchase  an
aggregate of 20,000  shares of Common Stock (the "Warrant A Shares" and "Warrant
B  Shares",  respectively).  The  Company  also  issued  to  Settondown  Capital
International  Ltd. (the "Placement  Agent") 50,000 shares of Common Stock and a
Warrant A to purchase an additional 20,000 shares (collectively,  the "Placement
Shares").

           The Put Option
           --------------

           During the  Commitment  Period,  the Company may,  from time to time,
exercise a "put"  right (the "Put  Option")  by  delivery of a put notice to the
Investors  pursuant to which the Investors must purchase the allotted  number of
shares indicated therein;  provided,  however,  that, unless the Company obtains
Stockholder  approval pursuant to the applicable  corporate  governance rules of
the Nasdaq  Stock  Market,  the Company may not compel the  Investors  to make a
purchase  which  results in the issuance to an Investor,  individually,  of more
than 19.99%


                                      -15-

<PAGE>



of the shares of Common Stock of the Company  including the Initial Shares.  The
maximum  number of shares  for which the  Company  may  deliver a put  notice is
subject to certain  limitations  based on the  trading  volume of the  Company's
Common Stock and the closing  price of the Common  Stock.  The Put Shares may be
purchased  at a 10%  discount  off the average of the three  lowest  closing bid
prices of the Common  Stock  during  the  Valuation  Period  (as  defined in the
Agreement).  The obligation of the Investors to purchase shares upon exercise by
the  Company  of a Put Option is subject to  limitations  and  termination  upon
occurrence of certain conditions set forth in the Agreement.

           The Initial Shares,  Warrant A and Warrant B were issued, and the Put
Shares,  the Warrant A Shares and the  Warrant B Shares  will be issued,  by the
Company in reliance upon the  provisions of Section 4(2) and Regulation D of the
Securities Act.

           Warrant A
           ---------

           The  Warrant A issued to the  Investors  and the  Placement  Agent in
connection with the Private Placement may be exercised, subject to the terms and
subject to the conditions set forth therein, at any time on or after October 15,
1998 and on or prior to October 15, 2003, to subscribe  for and purchase  shares
of Common Stock of the Company at an exercise price of $1.76. The exercise price
and the number of shares for which the  Warrant A is  exercisable  is subject to
adjustment as provided  therein,  including,  but not limited to,  anti-dilution
provisions  pertaining  to the  declaration  of stock  dividends and the merger,
consolidation or liquidation of the Company.

           Warrant B
           ---------

           The Warrant B issued to the Investors in connection  with the Private
Placement may be exercised,  subject to the terms and subject to the  conditions
set forth  therein,  at any time on or after October 15, 1998 and on or prior to
October 15, 2003,  to subscribe  for and purchase  shares of Common Stock of the
Company at an  exercise  price of $2.81.  The  exercise  price and the number of
shares  for which the  Warrant A is  exercisable  is subject  to  adjustment  as
provided  therein,  including,  but not  limited  to,  anti-dilution  provisions
pertaining to the declaration of stock  dividends and the merger,  consolidation
or liquidation of the Company.  The Company, at its option, may redeem Warrant A
for $0.01 per Warrant A Share by giving the holder  thereof  written notice (the
"Call  Notice")  at any  time  after  the  Registration  Statement  is  declared
effective,  and the  closing  bid price of the  Common  Stock of the  Company is
greater than one hundred fifty (150%)  percent of the exercise  price for twenty
(20) consecutive trading days.

           Placement Shares; Compensation to Placement Agent.
           --------------------------------------------------

           As compensation for services  rendered in connection with the Private
Placement,  the Company  issued to the  Placement  Agent 50,000 shares of Common
Stock (which are subject to a one year lock-up from the Subscription  Date), and
a Warrant A to purchase 20,000 shares of Common Stock.  The Company also paid to
the Placement Agent five (5%) percent of the Initial Shares  investment  amount.
The Company also agreed to pay to the Placement Agent, following the closing for
each Put Option,  five (5%) percent of the gross proceeds in cash, and five (5%)
percent  of the  number  of  shares of  Common  Stock  issuable  in total to the
Investors for each Put.

COMMON STOCK

           The  holders of the Common  Stock are  entitled  to one vote for each
share held of record on all matters  submitted  to a vote of  stockholders.  The
Company's 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  a
liquidation,  dissolution or winding up of the Company,  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 of the Company.  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 A PREFERRED STOCK

           On June 30, 1997, the Board of Directors authorized the issuance of a
series of Preferred  Stock  consisting  of 3,000 shares (the "Series A Preferred
Stock"),  each such  share of  Series A  Preferred  Stock has a stated  value of
$1,000 (the "Liquidation Preference"),  pursuant to a Certificate of Designation
(the "Certificate of Designation").  From September 29, 1997 to May 8, 1998, the
holders of the Series A Preferred  Stock  converted a portion of their  holdings
and as of May 8, 1998,  three different  entities owned the remaining 750 shares
of the Series A Preferred Stock. The Company has registered a total of 1,960,713
shares of Common  Stock  underlying  the  Series A  Preferred  Stock,  of which,
1,285,713  shares were  registered in a  registration  statement  filed with the
Commission  on  September  22,  1997  and  an  additional  675,000  shares  were
registered  in an  amendment  to such  registration  statement  filed  with  the
Commission on May 8, 1998. As of May 8, 1998,  1,503,217  shares of Common Stock
were issued in connection  with  conversions of Series A Preferred Stock and 750
shares of Series A Preferred Stock were outstanding.

           Dividends.  The holders of the shares of Series A Preferred Stock are
entitled to  receive,  when and as  declared  by the Board of  Directors  of the
Company,  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 A Preferred Stock from the date of initial  issuance.  Such dividends are
in preference to any distributions on any outstanding  shares of Common Stock or
any other  equity  securities  of the Company  that are junior to the  Preferred
Stock as to the payment of dividends.

           Preferences  on  Liquidation.  In  the  event  of  any  voluntary  or
involuntary  liquidation,  dissolution or winding up of the Company, the holders
of shares of the Series A Preferred Stock then outstanding  shall be entitled to
be paid,  out of the assets of the Company  available  for  distribution  to its
stockholders, an amount equal


                                      -17-

<PAGE>



to the  Liquidation  Preference for each share of Series A Preferred Stock owned
by such  holder,  plus all accrued and unpaid  dividends  thereon to the date of
payment.  If upon liquidation,  dissolution,  or winding up of the Company,  the
assets of the Company  available for distribution to its  stockholders  shall be
insufficient  to pay the  holders  of the  Series  A  Preferred  Stock  the full
Liquidation   Preference  plus  accrued  and  unpaid  dividends  to  which  they
respectively  shall be  entitled,  the holders of the Series A  Preferred  Stock
together  with the holders of any other series of Preferred  Stock  ranking on a
parity with the Series A  Preferred  Stock as to the  payments  of amounts  upon
liquidation,  dissolution or winding up shall share ratably in any  distribution
of assets according to the respective  amounts which would be payable in respect
of all  such  shares  held by the  respective  stockholders.  The  sale or other
disposition (for cash, shares of stock,  securities or other consideration),  of
all or  substantially  all of the assets of the Company  shall be deemed to be a
liquidation,  dissolution  or  winding  up of the  Company  but  the  merger  or
consolidation  of the Company into or with another  corporation  or into or with
the Company, shall not be deemed to be a liquidation,  winding up or dissolution
of the Company.  The holders of Series A Preferred  Stock shall have no priority
or preference  with respect to  distributions  made by the Company in connection
with the  repurchase  of shares of Common Stock issued to or held by  employees,
directors  or  consultants  upon  termination  of their  employment  or services
pursuant to agreements  providing for the right of said  repurchase  between the
Company and such persons.

           Conversion Rights. The holders of Series A Preferred Stock shall have
conversion  rights as follows:  (i) no shares of Series A Preferred Stock may be
converted prior to September 28, 1997; (ii) at any time after September 28, 1997
through  December 31, 1997,  up to  twenty-five  (25%)  percent of the shares of
Series A Preferred Stock then outstanding may be converted, at the option of the
holders  thereof;  and (iii)  thereafter,  on January 1, 1998, April 1, 1998 and
July 1, 1998, an additional  twenty-five (25%) percent of the shares of Series A
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 Series A 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) 82% 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 A Preferred
Stock has  telecopied a notice of  conversion  to the Company  (the  "Conversion
Date") and (B) $3.50.

           In the event the shares of Series A Preferred Stock are not converted
within  ten  business  days of  receipt  by the  Company  of a valid  notice  of
conversion, the Company shall pay to the holder, by wire transfer, as liquidated
damages  for such  failure  and not as a penalty,  an amount in cash equal to 1%
percent per day of the purchase price of the shares of Series A Preferred  Stock
to be converted which shall run from the initial  Conversion Date and the holder
has the option to withdraw the notice of conversion  previously sent;  provided,
that the Company shall not be responsible for or required to pay such liquidated
damages if such failure to convert was not caused by any actions or omissions of
the Company.

           No fractional  shares of Common Stock shall be issued upon conversion
of the Series A Preferred  Stock. In lieu of any fractional  shares to which the
holder would  otherwise be  entitled,  the Company  shall pay cash equal to such
fraction  multiplied  by the  fair  market  value  of the  Common  Stock  on the
Conversion Date, as determined by the Company's Board of Directors.  The Company
shall not be obligated  to issue  certificates  evidencing  the shares of Common
Stock issuable upon conversion  unless either the  certificates  evidencing such
shares of Series A Preferred  Stock are delivered to the Company or its transfer
agent as provided  above,  or the holder  notifies  the Company or its  transfer
agent that such certificates have been lost, stolen or destroyed and executes an
agreement  satisfactory  to the Company to  indemnify  the Company from any loss
incurred by it in connection with such certificates.

           Upon any conversion of Series A Preferred Stock, the shares of Series
A Preferred  Stock that are  converted  shall not be  reissued  and shall not be
considered  outstanding  for any  purposes.  Upon  conversion of all of the then
outstanding  Series A Preferred Stock,  shares of Series A Preferred Stock shall
not be deemed  outstanding for any purpose  whatsoever and all such shares shall
be retired and canceled and shall not be reissued.

           On June 30, 1999,  the holders of the Series A Preferred  Stock shall
be  required to convert  all of their  outstanding  shares of Series A Preferred
Stock  into  shares of Common  Stock.  Until  converted,  the  Company  shall be
entitled to redeem  shares of Series A Preferred  Stock in  accordance  with the
Certificate of Designation,  regardless of whether or not a notice of conversion
has been received by the Company with respect to such shares.

           The Company  shall at all times when any shares of Series A Preferred
Stock shall be outstanding, reserve and keep available out of its authorized but
unissued stock, such number of shares of Common Stock as shall from time to time
be sufficient to effect the  conversion  of all  outstanding  shares of Series A
Preferred Stock.

           Redemption. At any time after September 28, 1997, the Company may, at
the option of the Board of Directors, redeem up to 50% of the outstanding shares
of the Series A Preferred Stock at the applicable  redemption  price,  provided,
that (x) the Company  shall have  received a notice of  conversion,  and (y) the
Conversion  Price is at or below $2.625.  At any time after  September 28, 1997,
the  Company  may,  at the  option of the Board of  Directors,  redeem  all or a
portion of the remaining 50% of the outstanding shares of the Series A Preferred
Stock at the applicable redemption price,  provided,  that (x) the Company shall
have  received a notice of  conversion,  and (y) the  Conversion  Price is at or
below $1.00. The Company shall give written notice by telecopy, to the holder of
Series A 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 shall state the Redemption Date, the Redemption
Price (as hereinafter defined), the number of shares of Series A Preferred Stock
of such  holders to be redeemed and shall call upon such holders to surrender to
the Company on the  Redemption  Date at the place  designated in the notice such
holders'  redeemed stock.  If fewer than all the outstanding  shares of Series A
Preferred Stock are to be redeemed,  the redemption  shall be pro rata among the
holders of Series A Preferred Stock and subject to such other  provisions as may
be determined by the Board of Directors.  The  Redemption  Date shall be no more
than 10 days after  receipt of written  notice from the Company.  If the Company
fails to pay the Redemption  Price on the Redemption Date, the Company shall pay
to the  holder  a  penalty  in an  amount  in cash  equal to 2%  percent  of the
Redemption Price to be paid on such Redemption Date. If the Company fails to pay
the Redemption  Price on the Redemption Date, the holder shall have the right to
convert the Series A Preferred Stock previously presented to the Company and not
redeemed.  The  Company  shall have the right to redeem  the Series A  Preferred
Stock in any subsequent redemption; provided, however, that if the Company fails
to pay the  Redemption  Price in a  subsequent  redemption  within 10 days,  the
Company shall have the right to redeem the Series A Preferred  Stock  thereafter
only upon wiring the Redemption Price to the holders simultaneously with sending
the notice of redemption. On or after the Redemption Date, the holders of shares
of  Series  A  Preferred  Stock  called  for  redemption   shall  surrender  the
certificates  evidencing  the shares called for redemption to the Company at the
place  designated  in such  notice and shall  thereupon  be  entitled to receive
payment of the Redemption Price.

           The  Company  shall have the option to redeem the Series A  Preferred
Stock at a price  determined as follows  (each, a "Redemption  Price"):  (i) any
portion of the first 25% of the  outstanding  shares of Series A Preferred Stock
at a cash price equal to 110% percent of the  Liquidation  Preference per share,
together  with all unpaid  dividends to and including  the  Redemption  Date, or
issue shares of Common Stock at a conversion rate equal to (x) $1,000 divided by
(y) 82% percent 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


                                      -19-

<PAGE>



trading days preceding the Conversion  Date;  (ii) any portion of the second 25%
percent  of the  outstanding  shares of the Series A  Preferred  Stock at a cash
price equal to 120% of the Liquidation  Preference per share,  together with all
unpaid dividends to and including the Redemption Date, or issue shares of Common
Stock at a conversion rate equal to (x) $1,000 divided by (y) 82% 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  Conversion  Date;  and (iii) any  portion  of the
remaining  50% of the  outstanding  shares of Series A Preferred  Stock,  if the
Company receives a Notice of Conversion and the Conversion Price of the Series A
Preferred Stock is below $1.00, at a cash price equal to 110% of the Liquidation
Preference  per share,  together  with all accrued and unpaid  dividends  to and
including the Redemption Date; provided, however, that payment of the Redemption
Price shall be made from any funds of the Company legally available therefor.

           From and after the Redemption  Date (unless  default shall be made by
the Company in duly paying the Redemption  Price in which case all the rights of
the holders of such  shares  shall  continue),  the holders of the shares of the
Series A Preferred Stock called for redemption shall cease to have any rights as
stockholders of the Company, except the right to receive,  without interest, the
Redemption Price thereof upon surrender of certificates  representing the shares
of Series A Preferred Stock, and such shares shall not thereafter be transferred
(except  with the consent of the  Company) on the books of the Company and shall
not be deemed outstanding for any purpose whatsoever.

           There  shall be no  redemption  of any  shares of Series A  Preferred
Stock of the Company where such action would be in violation of applicable law.

           Call Option.  In the event the Company  closes on an offering for its
Common Stock at a price per share under  $6.00,  the Company may, at its option,
call all outstanding shares of Series A Preferred Stock at a call price equal to
200% of the Liquidation Preference.

           In the event the Company has an  offering  for its Common  Stock at a
price per share equal to or greater than $6.00, then the holders of the Series A
Preferred Stock shall be required to convert all outstanding  shares of Series A
Preferred  Stock into  shares of Common  Stock five  business  days prior to the
scheduled closing of such offering and each holder may, at its option,  sell its
shares of Common Stock as part of such offering.

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

           Status.  In case any  outstanding  shares of Series A 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 A Preferred Stock.

           Ranking;  Changes  Affecting  Series A Preferred  Stock. The Series A
Preferred   Stock  shall,   with  respect  to  dividend  rights  and  rights  on
liquidation, winding up and dissolution, (i) rank senior to any of the Company's
Common Stock and any other class or series of stock of the Company  which by its
terms shall rank junior to the Series A Preferred Stock, and (ii) rank junior to
any other class or series of stock of the Company  which by its terms shall rank
senior to the Series A Preferred Stock and (iii) rank on a pari passu basis with
the Series B  Preferred  Stock and any other  series of  Preferred  Stock of the
Company.

           So long as any shares of Series A  Preferred  Stock are  outstanding,
the  Company  shall  not (i)  alter or  change  any of the  powers  preferences,
privileges,  or  rights  of the  Series A  Preferred  Stock;  or (ii)  amend the
provisions of the Certificate of Designation affecting the ranking of the Series
A Preferred  Stock,  without  first  obtaining  the  approval by vote or written
consent, in the manner provided by law, of the holders of at least a majority of
the outstanding  shares of Series A Preferred Stock, as to changes affecting the
Series A Preferred Stock.

           Registration  Rights. The Company has registered the shares of Common
Stock underlying the Series A Preferred Stock in a registration  statement filed
with the Commission.

           SERIES B PREFERRED STOCK

           On November 12, 1997, the Board of Directors  authorized the issuance
of a series  of  Preferred  Stock  consisting  of 4,180  shares  (the  "Series B
Preferred  Stock"),  each such  share of Series B  Preferred  Stock has a stated
value of $1,000 (the  "Liquidation  Preference"),  pursuant to a Certificate  of
Designation  (the  "Certificate  of  Designation").  On November 12,  1997,  the
Company placed 3,180 shares of Series B Preferred Stock and on January 22, 1998,
placed the  remaining  1,000  shares.  The  Company  has  registered  a total of
3,327,663  shares of Common Stock  underlying the Series B Preferred  Stock,  of
which,  2,622,663  were  registered in a registration  statement  filed with the
Commission on January 2, 1998 and amended on January 22, 1998,  and 705,000 were
registered in a further amendment to such registration  statement filed with the
Commission  on May 8,  1998.  As of May 8, 1998,  all of the Series B  Preferred
Stock had been converted to Common Stock  resulting in the issuance of 3,172,239
shares of Common Stock.

           Dividends.  The holders of the shares of Series B Preferred Stock are
entitled to  receive,  when and as  declared  by the Board of  Directors  of the
Company,  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 B Preferred Stock from the date of initial  issuance.  Such dividends are
in preference to any distributions on any outstanding  shares of Common Stock or
any other  equity  securities  of the Company  that are junior to the  Preferred
Stock as to the payment of dividends.

           Preferences  on  Liquidation.  In  the  event  of  any  voluntary  or
involuntary  liquidation,  dissolution or winding up of the Company, the holders
of shares of the Series B Preferred Stock then outstanding  shall be entitled to
be paid,  out of the assets of the Company  available  for  distribution  to its
stockholders,  an amount equal to the  Liquidation  Preference for each share of
Series B  Preferred  Stock  owned by such  holder,  plus all  accrued and unpaid
dividends thereon to the date of payment. If upon liquidation,  dissolution,  or
winding up of the Company,  the assets of the Company available for distribution
to its  stockholders  shall be  insufficient  to pay the holders of the Series B
Preferred  Stock  the  full  Liquidation  Preference  plus  accrued  and  unpaid
dividends  to which they  respectively  shall be  entitled,  the  holders of the
Series B  Preferred  Stock  together  with the  holders  of any other  series of
Preferred  Stock ranking on a parity with the Series B Preferred Stock as to the
payments  of amounts  upon  liquidation,  dissolution  or winding up shall share
ratably in any distribution of assets according to the respective  amounts which
would  be  payable  in  respect  of all  such  shares  held  by  the  respective
stockholders.  The  sale or  other  disposition  (for  cash,  shares  of  stock,
securities or other consideration), of all or substantially all of the assets of
the Company shall be deemed to be a  liquidation,  dissolution  or winding up of
the Company but the merger or  consolidation of the Company into or with another
corporation  or  into  or  with  the  Company,  shall  not  be  deemed  to  be a
liquidation,  winding up or dissolution of the Company.  The holders of Series B
Preferred   Stock  shall  have  no  priority  or  preference   with  respect  to
distributions made by the Company in connection with the repurchase of shares of
Common Stock issued to or held by employees, directors


                                      -21-

<PAGE>



or  consultants  upon  termination of their  employment or services  pursuant to
agreements  providing for the right of said  repurchase  between the Company and
such persons.

           Conversion Rights. The holders of Series B Preferred Stock shall have
conversion  rights as follows:  (i) no shares of Series B Preferred Stock may be
converted  prior to the earlier of (x) the  effective  date of the  Registration
Statement  covering the Shares and (y) February 10, 1998 (the "First  Conversion
Date"); (ii) during the thirty-day period after the First Conversion Date, up to
twenty-five  (25%)  percent  of the  shares of  Series B  Preferred  Stock  then
outstanding may be converted,  at the option of the holders  thereof;  and (iii)
during each  thirty-day  period  thereafter,  an  additional  twenty-five  (25%)
percent  of the  shares of Series B  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  Series  B  Preferred  Stock  may be  converted  shall be
determined  by  dividing  the  Liquidation  Preference  and at the option of the
Company,  accrued and unpaid  dividends,  by an amount (the "Conversion  Price")
equal  to the 85% of the  average  closing  bid  price  of the  Common  Stock as
reported  on the Nasdaq  SmallCap  Market or any  successor  exchange or trading
market  in which  the  Common  Stock is listed  for the five  trading  days (the
"Average Trading Price")  preceding the date on which the holder of the Series B
Preferred  Stock has  telecopied  a notice of  conversion  to the  Company  (the
"Conversion  Date").  The Conversion Price shall not be greater than 120% of the
Average  Trading  Price on the date of  issuance  or less than an initial  floor
price of 50% of the Conversion Price on the date of issuance.  Commencing thirty
days after the First  Conversion Date and at the end of each  thirty-day  period
thereafter, the initial floor price will be reduced by 10%.

           In the event the shares of Series B Preferred Stock are not converted
within  ten  business  days of  receipt  by the  Company  of a valid  notice  of
conversion, the Company shall pay to the holder, by wire transfer, as liquidated
damages  for such  failure  and not as a penalty,  an amount in cash equal to 1%
percent per day of the purchase price of the shares of Series B Preferred  Stock
to be converted which shall run from the initial  Conversion Date and the holder
has the option to withdraw the notice of conversion  previously sent;  provided,
that the Company shall not be responsible for or required to pay such liquidated
damages if such failure to convert was not caused by any actions or omissions of
the Company.

           No fractional  shares of Common Stock shall be issued upon conversion
of the Series B Preferred  Stock. In lieu of any fractional  shares to which the
holder would  otherwise be  entitled,  the Company  shall pay cash equal to such
fraction  multiplied  by the  fair  market  value  of the  Common  Stock  on the
Conversion Date, as determined by the Company's Board of Directors.  The Company
shall not be obligated  to issue  certificates  evidencing  the shares of Common
Stock issuable upon conversion  unless either the  certificates  evidencing such
shares of Series B Preferred  Stock are delivered to the Company or its transfer
agent as provided  above,  or the holder  notifies  the Company or its  transfer
agent that such certificates have been lost, stolen or destroyed and executes an
agreement  satisfactory  to the Company to  indemnify  the Company from any loss
incurred by it in connection with such certificates.

           Upon any conversion of Series B Preferred Stock, the shares of Series
B Preferred  Stock that are  converted  shall not be  reissued  and shall not be
considered  outstanding  for any  purposes.  Upon  conversion of all of the then
outstanding  Series B Preferred Stock,  shares of Series B Preferred Stock shall
not be deemed  outstanding for any purpose  whatsoever and all such shares shall
be retired and canceled and shall not be reissued.

           On November  12,  1999,  the holders of the Series B Preferred  Stock
shall be  required  to  convert  all of their  outstanding  shares  of  Series B
Preferred Stock into shares of Common Stock. Until converted, the Company


                                      -22-

<PAGE>



shall be entitled to redeem  shares of Series B  Preferred  Stock in  accordance
with the  Certificate of  Designation,  regardless of whether or not a notice of
conversion has been received by the Company with respect to such shares.

           The Company  shall at all times when any shares of Series B Preferred
Stock shall be outstanding, reserve and keep available out of its authorized but
unissued stock, such number of shares of Common Stock as shall from time to time
be sufficient to effect the  conversion  of all  outstanding  shares of Series B
Preferred Stock.

           Redemption.  At any time after the date of  issuance  of the Series B
Preferred  Stock,  the  Company  may,  at the option of the Board of  Directors,
redeem any or all of the  outstanding  shares of the Series B Preferred Stock at
the applicable redemption price, provided,  that the holder shall have the right
to convert shares of Series B Preferred  Stock which are eligible for conversion
in the first five (5) days after  receiving a notice of  redemption up to 20% of
the Series B Preferred Stock in the aggregate owned by such holder.  The Company
shall give written notice by telecopy, to the holder of Series B Preferred Stock
to be redeemed,  which notice shall specify the date for redemption,  which date
shall be no later than five (5) business days after the date on which the notice
is delivered to the holder (the  "Redemption  Date"),  the Redemption  Price (as
hereinafter  defined),  the number of shares of Series B Preferred Stock of such
holders to be  redeemed  and shall call upon such  holders to  surrender  to the
Company  on the  Redemption  Date at the place  designated  in the  notice  such
holders'  redeemed stock.  If fewer than all the outstanding  shares of Series B
Preferred Stock are to be redeemed,  the redemption  shall be pro rata among the
holders of Series B Preferred Stock and subject to such other  provisions as may
be determined by the Board of Directors.  The  Redemption  Date shall be no more
than five (5) business days after receipt of written notice from the Company. If
the  Company  fails to pay the  Redemption  Price on the  Redemption  Date,  the
Company  shall  pay to the  holder  a  penalty  in an  amount  in cash  equal to
$100,000.  If the Company fails to pay the  Redemption  Price on the  Redemption
Date,  the Company  shall have the right to redeem the Series B Preferred  Stock
thereafter only upon wiring the Redemption  Price to the holders  simultaneously
with sending the notice of  redemption.  On or after the  Redemption  Date,  the
holders  of shares of Series B  Preferred  Stock  called  for  redemption  shall
surrender the  certificates  evidencing  the shares called for redemption to the
Company at the place  designated in such notice and shall  thereupon be entitled
to receive payment of the Redemption Price.

           The  Company  shall have the option to redeem all or a portion of the
outstanding  shares of Series B  Preferred  Stock at a cash price  equal to 122%
percent  of the  Liquidation  Preference  per  share,  together  with all unpaid
dividends  to and  including  the  Redemption  Date  (the  "Redemption  Price");
provided,  however,  that payment of the Redemption Price shall be made from any
funds of the Company legally available therefor.

           From and after the Redemption  Date (unless  default shall be made by
the Company in duly paying the Redemption  Price in which case all the rights of
the holders of such  shares  shall  continue),  the holders of the shares of the
Series B Preferred Stock called for redemption shall cease to have any rights as
stockholders of the Company, except the right to receive,  without interest, the
Redemption Price thereof upon surrender of certificates  representing the shares
of Series B Preferred Stock, and such shares shall not thereafter be transferred
(except  with the consent of the  Company) on the books of the Company and shall
not be deemed outstanding for any purpose whatsoever.

           There  shall be no  redemption  of any  shares of Series B  Preferred
Stock of the Company where such action would be in violation of applicable law.

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

           Ranking;  Changes  Affecting  Series B Preferred  Stock. The Series B
Preferred   Stock  shall,   with  respect  to  dividend  rights  and  rights  on

                    DELAWARE BUSINESS COMBINATION PROVISIONS

           As a Delaware  corporation,  the  Company  is 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  the  entire  interest  in the  Company  if such  acquisition  is not
approved by the Company's 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 its 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 Company's  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  Company's  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. The  Company's
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

           The  distribution  of the Shares by the Selling  Stockholders  may be
effected from time to time in one or more transactions  (which may involve block
transactions),  in special offerings,  exchange  distributions  and/or secondary
distributions,  in  negotiated  transactions,  in  settlement  of short sales of
Shares, or a combination or such methods of sale, at market prices prevailing at
the time of sale,  at prices  related  to such  prevailing  market  prices or at
negotiated prices. Such transactions may be effected on a stock exchange, on the
over-the-counter  market or privately.  The Selling Stockholders may effect such
transactions  by  selling  the  Shares to or  through  broker-dealers,  and such
broker-dealers may receive  compensation in the form of underwriting  discounts,
concessions or commissions  from the Selling  Stockholders for whom they may act
as agent (which compensation may be in excess of customary commissions). Without
limiting the  foregoing,  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 Selling  Stockholders and any  broker-dealers  or other persons
acting on the behalf of parties that participate with such Selling  Stockholders
in the  distribution  of the  Shares  may be deemed to be  underwriters  and any
commissions  received or profit realized by them 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,  the Company is not aware of any  agreement,
arrangement  or  understanding  between  any  broker or dealer  and the  Selling
Stockholders  with  respect to the offer or sale of the Shares  pursuant to this
Prospectus.

           At the time that any  particular  offering of Shares is made,  to the
extent  required  by  the  Securities  Act,  a  prospectus  supplement  will  be
distributed,  setting forth the terms of the  offering,  including the aggregate
number of  Shares  being  offered,  the names of any  underwriters,  dealers  or
agents,  any discounts,  commissions and other items  constituting  compensation
from the Selling  Stockholders  and any  discounts,  commissions  or concessions
allowed or reallowed or paid to dealers.

           Each of the  Selling  Stockholders  may from time to time  pledge the
Shares  owned  by it to  secure  margin  or  other  loans  made to such  Selling
Stockholder. Thus, the person or entity receiving the pledge of any of the


                                      -25-

<PAGE>



Shares may sell them, in a foreclosure sale or otherwise,  in the same manner as
described above for such Selling Stockholder.

           The Company will not receive any of the proceeds from any sale of the
Shares by the Selling Stockholders offered hereby.

           Pursuant to the Registration  Rights Agreements,  the Company and the
Selling  Stockholders  have  agreed to  indemnify  each  other  against  certain
liabilities,  including  liabilities under the Securities Act. The Company shall
bear  customary  expenses  incident  to the  registration  of the Shares for the
benefit of the Selling  Stockholders 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 Selling Stockholders.

           The Company has agreed to maintain  the  Registration  Statement,  of
which this  Prospectus  is a part,  effective  until the earlier of (i) the date
that all of the Shares  registered under such  Registration  Statement have been
sold; (ii) the date the holders of the Shares receive an opinion of counsel that
all of the Shares may be sold under the provisions of Rule 144 or (iii) five and
one-half years after the completion of the Private Placement.

                 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 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 its
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 its
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  its
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 its
directors  and officers  which may, in some cases,  be broader than the specific
indemnification provisions


                                      -26-

<PAGE>



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.

           Pursuant to the Registration  Rights  Agreement,  the Company and the
Selling  Stockholders  have  agreed to  indemnify  each  other  against  certain
liabilities, including liabilities under the Securities Act.

           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.

           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

           The validity of the securities offered hereby will be passed upon for
the Company by Parker Chapin Flattau & Klimpl,  LLP, New York, New York.  Martin
Eric  Weisberg,  Esq., a member of the firm,  is a Director and the Secretary of
the Company.

                                     EXPERTS

           The consolidated  balance sheets as of December 31, 1997 and 1996 and
the related consolidated statements of operations, stockholders' equity and cash
flows for the years then ended,  incorporated  by reference in this  Prospectus,
have been  incorporated  herein in reliance on the report  dated March 31, 1998,
which includes an  explanatory  paragraph,  concerning the Company's  ability to

accountants, given on their authority as experts in accounting and auditing.

ITEM 15.  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 its
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 its
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  its
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 its
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

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.

Genesis  Insurance  Company that contains a limit of liability of $3,000,000 per

ITEM 17.  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.  Notwithstanding the foregoing,
            any  increase or decrease  in volume of  securities  offered (if the
            total dollar value of securities offered would not exceed that which
            was  registered)  and any deviation  from the low or high and of the
            estimated  maximum  offering  range may be  reflected in the form of
            prospectus filed with the Commission  pursuant to Rule 424(b) if, in
            the  aggregate,  the changes in volume and price  represent  no more
            than 20 percent change in the maximum  aggregate  offering price set
            forth  in  the  "Calculation  of  Registration  Fee"  table  in  the
            effective registration statement.

                  (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;



                                     II - 2

<PAGE>



            (2)   That, for the purpose of determining  any liability  under the
            Securities Act of 1933, each such post-effective  amendment 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.

            (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  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.

            In  the  event  that  a  claim  for  indemnification   against  such
liabilities  (other  than the payment by the small  business  issuer of expenses
incurred  or paid by a  director,  officer  or  controlling  person of the small
business issuer in the successful defense of any action,  suit or proceeding) is
asserted by such director,  officer or controlling person in connection with the
securities  being  registered,  the small  business  issuer will,  unless in the
opinion of its 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  Securities
Act and will be governed by the final adjudication of the issue.

            The undersigned  small business issuer hereby  undertakes  that, for
purposes of determining  any liability  under the  Securities Act of 1933,  each
filing of the  registrant's  annual report  pursuant to section 13(a) or section
15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing
of an employee  benefit  plan's annual  report  pursuant to section 15(d) of the
Securities  Exchange  Act of 1934)  that is  incorporated  by  reference  in the
registration  statement  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.

           Pursuant  to the  requirements  of the  Securities  Act of 1933,  the
registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-3 and has duly caused this registration
statement  to be  signed  on its  behalf  by  the  undersigned,  thereunto  duly

(including,  without  limitation,  the provisions of Article VII hereof), on any
Put Date the Company may make a Put by the delivery of a Put Notice/  Compliance
Certificate  in the form attached  hereto as Exhibit D. The number of Put Shares

on such date.

obtains  Shareholder  approval pursuant to the applicable  corporate  governance
rules of the Nasdaq  Stock  Market,  the Investor may not be compelled to make a

the shares of Common Stock (measured from the Subscription  Date) as a result of
the transactions contemplated by this Agreement.

           Section 2.2   Mechanics.

than $100,000 nor more than the Maximum Put Amount.

           (b)        Date of  Delivery  of Put  Notice.  A Put Notice  shall be
deemed delivered on (i) the Trading Day it is received by facsimile or otherwise
by the Investor if such notice is received  prior to 2:00 p.m.  Eastern Time, or
(ii) the  immediately  succeeding  Trading Day if it is received by facsimile or
otherwise after 2:00 p.m.  Eastern Time on a Trading Day or at any time on a day
which is not a Trading Day. No Put Notice may be deemed delivered, on a day that
is not a Trading Day.

           Section 2.3 Closings.  On each Closing Date for a Put (i) the Company
shall  deliver (a) to the Escrow  Agent for the benefit of the  Investor  one or
more certificates,  at the Investor's option,  representing the Put Shares to be
purchased by the Investor pursuant to Section 2.1 herein, registered in the name
of the Investor or, at the Investor's option,  deposit such  certificate(s) into
such account or accounts previously  designated by the Investor,  and (b) to the
Escrow Agent for the  Placement  Agent that number of shares of Common Stock set
forth in  Section  13.7;  and (ii) the  Investor  shall  deliver  to escrow  the
Investment  Amount  specified in the Put Notice by wire transfer of  immediately
available  funds to the Escrow Agent on or before the Closing Date. In addition,
on or prior to the Closing Date, each of the Company,  the Placement  Agent, and
the Investor  shall deliver to the Escrow Agent all documents,  instruments  and
writings  required to be  delivered  or  reasonably  requested by either of them
pursuant to this  Agreement  in order to implement  and effect the  transactions

Date out of  escrow in  accordance  with the  escrow  agreement  referred  to in
Section 7.2 (m); provided,  however, that to the extent the Company has not paid
the fees,  expenses,  and disbursements of the Investor's counsel, and Placement
Agent in accordance  with Section 13.7, the amount of such fees,  expenses,  and
disbursements shall be paid in immediately  available funds, at the direction of
the  Investor,  to  Investor's  counsel  with no  reduction in the number of Put
Shares issuable to the Investor on such Closing Date.

event  that  (i)  there  shall  occur  any  stop  order  or  suspension  of  the
effectiveness  of the  Registration  Statement  for an  aggregate of twenty (20)
Trading Days during the Commitment  Period,  for any reason other than deferrals

at the New Bid Price pursuant to an effective  Registration  Statement,  and the
Company shall issue to the Investor a number of  additional  shares equal to the
difference between (y) the product of the number of Registrable  Securities held
by the Investor  during such  "blackout  period" that are not  otherwise  freely
tradeable and the Old Bid Price, divided by the New Bid Price and (z) the number
of Registrable  Securities  held by the Investor  during such "blackout  period"
that are not otherwise freely tradeable.

           Section 2.7  Liquidated  Damages.  In the event that the Company does
not deliver  unlegended  Common Stock in connection with the sale of such Common
Stock by the Investor as set forth in Article IX below,  within five (5) Trading
Days of  surrender by the  Investor of the Common  Stock  certificate  as is set
forth in Article IX below (such date of receipt is  referred to as the  "Receipt
Date"), the Company shall pay to the Investor,  in immediately  available funds,
upon demand,  as liquidated  damages for such failure and not as a penalty,  one

Investor's original Purchase Price of the Common Stock (the "Repurchase Price").
Upon receipt by Investor of notice by the Company (the  "Repurchase  Notice") of
its right to repurchase  the  aforementioned  shares of Common Stock held by the
Investor  (the  "Repurchase   Date"),   the  Company  shall  wire  transfer  the
appropriate  amount of funds into an escrow account mutually agreed upon by both
the Company and Investor within three (3) business days of the Repurchase  Date.
Additionally,  if the Company has not deposited into escrow the Repurchase Price
for the  benefit  of the  Investor,  within  three (3)  business  days after the
Repurchase  Date,  the Company  shall have waived its right to repurchase at any
time, and shall pay to the Investors, in immediately available funds, liquidated
damages in the amount of ten (10%) percent of the Repurchase Price.  However, in
no event shall the Company:  (i) be allowed to send a  Repurchase  Notice to the
Investor within five (5) days of a Repricing Date, or within five (5) days after
any Repricing Date, or (ii) be entitled to repurchase any Put Shares.

obligations under said Act.

prospectus or any document  incorporated or deemed to be incorporated therein by
reference  untrue in any  material  respect or that  requires  the making of any
changes in the Registration Statement,  related prospectus or documents so that,
in the case of the  Registration  Statement,  it will  not  contain  any  untrue
statement of a material  fact or omit to state any material  fact required to be

<PAGE>



           (a)        Accuracy of the Investor's  Representation and Warranties.
The  representations and warranties of the Investor shall be true and correct in
all  material  respects as of the date of this  Agreement  and as of the date of
each such Closing as though made at each such time.

           (b)        Performance  by the  Investor.  The  Investor  shall  have
performed, satisfied and complied in all respects with all covenants, agreements
and conditions required by this Agreement to be performed, satisfied or complied
with by the Investor at or prior to such Closing.

           Section  7.2  Conditions  Precedent  to the Right of the  Company  to
Deliver a Put Notice and the  Obligation of the Investor to Purchase Put Shares.
The right of the  Company  to deliver a Put  Notice  and the  obligation  of the
Investor  hereunder to acquire and pay for the Put Shares  incident to a Closing
is subject to the  satisfaction,  on (i) the date of delivery of such Put Notice
and (ii) the applicable Closing Date (each a "Condition  Satisfaction Date"), of
each of the following conditions:

           (a)        Registration of the Common Stock with the SEC. The Company
shall have  filed  with the SEC a  Registration  Statement  with  respect to the
resale  of the  Registrable  Securities  in  accordance  with  the  terms of the
Registration  Rights  Agreement.   As  set  forth  in  the  Registration  Rights
Agreement,  the Registration Statement (which includes all Put Shares in the Put
Notice) shall have  previously  become  effective and shall remain  effective on
each  Condition  Satisfaction  Date and (i) neither the Company nor the Investor
shall have  received  notice  that the SEC has issued or intends to issue a stop
order with respect to the  Registration  Statement or that the SEC otherwise has
suspended or withdrawn the effectiveness of the Registration  Statement,  either
temporarily  or  permanently,  or intends or has threatened to do so (unless the
SEC's concerns have been addressed and the Investor is reasonably satisfied that
the SEC no longer is  considering  or intends to take such action),  and (ii) no
other  suspension  of  the  use  or  withdrawal  of  the  effectiveness  of  the
Registration  Statement  or related  prospectus  shall exist.  The  Registration
Statement  must have been  declared  effective by the SEC prior to the first Put
Date.

           (b)        Authority. The Company shall have obtained all permits and
qualifications  required  by any state for the offer and sale of the Put Shares,
or shall have the availability of exemptions therefrom. The sale and issuance of
the Put Shares shall be legally  permitted by all laws and  regulations to which
the Company is subject.


           (c)        Accuracy of the Company's  Representations and Warranties.
The  representations  and warranties of the Company shall be true and correct in
all material  respects as of each Condition  Satisfaction Date as though made at
each such time (except for representations  and warranties  specifically made as
of a  particular  date) with  respect to all  periods,  and as to all events and
circumstances occurring or existing to and including each Condition Satisfaction
Date,   except   for  any   conditions   which  have   temporarily   caused  any
representations  or  warranties  herein  to be  incorrect  and  which  have been
corrected with no continuing impairment to the Company or the Investor.

           (d)        Performance  by  the  Company.   The  Company  shall  have
performed,  satisfied and complied in all material  respects with all covenants,
agreements and conditions  required by this Agreement,  the Registration  Rights
Agreement  and Warrants A and B to be  performed,  satisfied or complied with by
the Company at or prior to each Condition Satisfaction Date.

           (e)        No Injunction.  No statute,  rule,  regulation,  executive
order,  decree,   ruling  or  injunction  shall  have  been  enacted,   entered,
promulgated  or endorsed by any court or  governmental  authority  of  competent
jurisdiction  that  prohibits  or  directly  and  adversely  affects  any of the
transactions contemplated by this Agreement, and no


                                       17
<PAGE>



proceeding  shall have been commenced that may have the effect of prohibiting or
adversely affecting any of the transactions contemplated by this Agreement.

           (f)        Adverse Changes. Since the date of filing of the Company's
most recent SEC Document,  no event that had or is  reasonably  likely to have a
Material Adverse Effect has occurred.

           (g)        No  Suspension of Trading In or Delisting of Common Stock.
The trading of the Common Stock (including,  without limitation, the Put Shares)
is not  suspended  by the SEC or the  Principal  Market,  and the  Common  Stock
(including,  without  limitation,  the Put Shares)  shall have been approved for
listing or  quotation  on and shall not have been  delisted  from the  Principal
Market.  The issuance of shares of Common  Stock with respect to the  applicable
Closing, if any, shall not violate the shareholder approval  requirements of the
Principal Market. The Company shall not have received any notice threatening the
listing of the Common Stock on the Principal Market.

           (h)        4.99% Percent Limitation. On each Closing Date, the number
of Put Shares then to be purchased by the Investor  exceeding the number of such
shares which,  when  aggregated with all other shares of Common Stock then owned
by the Investor beneficially or deemed beneficially owned by the Investor, would
result in the Investor  owning no more than 4.99% of all of such Common Stock as
would be outstanding on such Closing Date, as determined in accordance with Rule
13d-3  of the  Exchange  Act and the  regulations  promulgated  thereunder.  For
purposes of this  Section  7.2(i),  in the event that the amount of Common Stock
outstanding as determined in accordance  with Rule 13d-3 of the Exchange Act and
the regulations  promulgated thereunder is greater on a Closing Date than on the
date upon which the Put Notice  associated with such Closing Date is given,  the
amount of Common  Stock  outstanding  on such  Closing  Date  shall  govern  for
purposes of determining whether the Investor,  when aggregating all purchases of
Common Stock made pursuant to this Agreement and, if any, Warrant Shares,  would
own more than 4.99% of the Common Stock following such Closing.

           (i)        Minimum Average Trading Volume. The average trading volume
for the Common  Stock over the previous  thirty (30) Trading Days exceeds  5,000
shares per Trading Day.

           (j)        No  Knowledge.  The Company has no  knowledge of any event
more likely than not to have the effect of causing such  Registration  Statement
to be suspended or otherwise ineffective (which event is more likely than not to
occur within the ten Trading Days following the Trading Day on which such Notice
is deemed delivered).

           (k)        Trading  Cushion.  The Trading  Cushion shall have elapsed
since the next preceding Put Date.

           (l)        Escrow  Agreement.  The parties  hereto shall have entered
into a mutually acceptable escrow agreement.

           (m)        Legal Opinion.  On the first Closing of the Put Shares the
Investor shall receive an opinion from counsel to the Company  substantially  in
the form of Exhibit F annexed  hereto.  The  Investor  shall only be entitled to
receive such an opinion of counsel on one  occasion  during each ninety (90) day
period  following  the Closing Date of the first Put. For example,  the Investor
shall not be entitled to receive an opinion of Company  counsel in the event the
Closing Date for a subsequent  Put is within  ninety (90) days after the Closing
Date for the preceding Put.  However,  the Investor is entitled to an opinion of
Company  counsel in the event the  Closing  Date for the second Put is more than
ninety (90) days after the first Put.

           (n)        Other. On each Condition  Satisfaction  Date, the Investor
shall have received and been reasonably  satisfied with such other  certificates
and documents as shall have been reasonably requested by the Investor in


                                       18
<PAGE>



order for the Investor to confirm the Company's  satisfaction  of the conditions
set forth in this Section 7.2, including,  without limitation,  a certificate in
substantially  the form and  substance  of Exhibit D hereto,  executed in either
case by an  executive  officer of the  Company  and to the  effect  that all the
conditions to such Closing shall have been satisfied as at the date of each such
certificate.

           Section 8.1 Due Diligence  Review.  The Company shall make  available
for inspection and review by the Investor,  advisors to and  representatives  of
the  Investor  (who may or may not be  affiliated  with the Investor and who are
reasonably  acceptable to the Company),  any  underwriter  participating  in any
disposition of the Registrable  Securities on behalf of the Investor pursuant to
the  Registration  Statement,  any such  registration  statement or amendment or
supplement  thereto or any blue sky,  NASD or other  filing,  all  financial and
other  records,  all SEC Documents and other filings with the SEC, and all other
corporate documents and properties of the Company as may be reasonably necessary
for the purpose of such review, and cause the Company's officers,  directors and
employees to supply all such information reasonably requested by the Investor or
any  such  representative,  advisor  or  underwriter  in  connection  with  such
Registration  Statement  (including,  without  limitation,  in  response  to all
questions  and other  inquiries  reasonably  made or  submitted by any of them),
prior to and  from  time to time  after  the  filing  and  effectiveness  of the
Registration  Statement  for the sole  purpose of enabling the Investor and such
representatives,  advisors and underwriters and their respective accountants and
attorneys  to conduct  initial  and ongoing due  diligence  with  respect to the
Company and the accuracy of the Registration Statement.

           Section 8.2         Non-Disclosure of Non-Public Information

           (a)        The Company shall not disclose  non-public  information to
the Investor,  advisors to or  representatives  of the Investor  unless prior to
disclosure of such information the Company  identifies such information as being
non-public   information   and  provides  the   Investor,   such   advisors  and
representatives  with the  opportunity  to  accept  or  refuse  to  accept  such
non-public information for review. The Company may, as a condition to disclosing
any  non-public  information  hereunder,  require the  Investor's  advisors  and
representatives  to enter into a  confidentiality  agreement in form  reasonably
satisfactory to the Company and the Investor.

           (b)        Nothing  herein  shall  require  the  Company to  disclose
non-public  information to the Investor or its advisors or representatives,  and
the Company  represents that it does not disseminate  non-public  information to
any investors who purchase stock in the Company in a public  offering,  to money
managers or to securities  analysts,  provided,  however,  that  notwithstanding
anything  herein to the contrary,  the Company will,  as  hereinabove  provided,
immediately notify the advisors and representatives of the Investor and, if any,
underwriters,  of any event or the  existence of any  circumstance  (without any
obligation to disclose the specific event or  circumstance)  of which it becomes
aware,  constituting  non-public  information  (whether or not  requested of the
Company  specifically  or generally  during the course of due  diligence by such
persons or entities),  which, if not disclosed in the prospectus included in the
Registration  Statement  would  cause  such  prospectus  to  include a  material
misstatement  or to omit a material fact required to be stated  therein in order
to make the statements,  therein,  in light of the  circumstances  in which they
were made,  not  misleading.  Nothing  contained  in this  Section  8.2 shall be
construed to mean that such persons or entities other than the Investor (without
the written consent of the Investor prior to disclosure of such information) may
not obtain  non-public  information in the course of conducting due diligence in
accordance with the terms of this Agreement and nothing herein shall prevent any


                                       19
<PAGE>



such persons or entities from  notifying the Company of their opinion that based
on such due  diligence  by such  persons  or  entities,  that  the  Registration
Statement  contains an untrue  statement of a material  fact or omits a material
fact  required to be stated in the  Registration  Statement or necessary to make
the statements  contained  therein,  in light of the circumstances in which they
were made, not misleading.

                                     Legends

           Section  9.1  Legends.   Unless   otherwise   provided  below,   each
certificate  representing  Registrable Securities will bear the following legend
(the "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.  THE HOLDER OF
           THIS  CERTIFICATE IS THE  BENEFICIARY  OF CERTAIN  OBLIGATIONS OF THE
           COMPANY SET FORTH IN A PRIVATE EQUITY LINE OF CREDIT  AGREEMENT DATED
           AS OF  APRIL  13,  1998.  A COPY  OF  THE  PORTION  OF THE  AFORESAID
           AGREEMENT  EVIDENCING  SUCH  OBLIGATIONS  MAY BE  OBTAINED  FROM  THE
           COMPANY'S EXECUTIVE OFFICES.

           Upon the execution and delivery hereof, the Company is issuing to the
transfer  agent for its  Common  Stock  (and to any  substitute  or  replacement
transfer  agent for its Common Stock upon the Company's  appointment of any such
substitute or replacement transfer agent) instructions in substantially the form
of Exhibit G hereto.  Such instructions shall be irrevocable by the Company from
and after the date  hereof or from and after the  issuance  thereof  to any such
substitute  or  replacement  transfer  agent,  as the  case  may be,  except  as
otherwise  expressly  provided in the Registration  Rights Agreement.  It is the
intent and purpose of such  instructions,  as provided  therein,  to require the
transfer  agent  for  the  Common  Stock  from  time to time  upon  transfer  of
Registrable  Securities by the Investor to issue  certificates  evidencing  such
Registrable Securities free of the Legend during the following periods and under
the following  circumstances and without consultation by the transfer agent with
the  Company or its  counsel  and  without  the need for any  further  advice or
instruction or documentation to the transfer agent by or from the Company or its
counsel or the Investor:

           (a)        at any time after the Effective  Date,  upon  surrender of
one or more  certificates  evidencing  Common Stock that bear the Legend, to the
extent  accompanied by a notice requesting the issuance of new certificates free
of the Legend to replace those  surrendered;  provided that (i) the Registration
Statement  shall then be effective;  (ii) the Investor  confirms to the transfer
agent that it has sold,  pledged  or  otherwise  transferred  or agreed to sell,
pledge or otherwise  transfer such Common Stock in a bona fide  transaction to a
third party that is not an  affiliate  of the  Company;  and (iii) the  Investor
confirms  to the  transfer  agent  that  the  Investor  has  complied  with  the
prospectus  delivery  requirement.  The  requirements  set  forth in  subsection
9.1(a)(ii) and 9.1(a)(iii)  shall only apply in the event the Company  registers
the Common Stock pursuant to a Form S-3


                                       20
<PAGE>



registration  statement  pursuant to the Registration  Rights Agreement.  In the
event  the  Company  registers  the  Common  Stock by  means  of a  registration
statement other then a Form S-3 registration statement,  than only the condition
in subsection 9.1(a)(i) herein shall apply.

           (b)        at any time upon any surrender of one or more certificates
evidencing   Registrable   Securities  that  bear  the  Legend,  to  the  extent
accompanied by a notice  requesting the issuance of new certificates free of the
Legend to replace those surrendered and containing  representations that (i) the
Investor  is  permitted  to  dispose  of  such  Registrable  Securities  without
limitation  as to amount or manner of sale  pursuant  to Rule  144(k)  under the
Securities Act or (ii) the Investor has sold,  pledged or otherwise  transferred
or agreed to sell, pledge or otherwise transfer such Registrable Securities in a
manner  other  than  pursuant  to  an  effective  registration  statement,  to a
transferee  who  will  upon  such  transfer  be  entitled  to  freely  tradeable
securities.

           Any of the notices  referred to above in this Section 9.1 may be sent
by facsimile to the Company's transfer agent.

           Section 9.2 No Other Legend or Stock Transfer Restrictions. No legend
other than the one  specified  in Section 9.1 has been or shall be placed on the
share  certificates  representing  the Common Stock and no instructions or "stop
transfer   orders,"  so  called,   "stock  transfer   restrictions,"   or  other
restrictions  have been or shall be given to the Company's  transfer  agent with
respect thereto other than as expressly set forth in this Article IX.

           Section 9.3  Investor's  Compliance.  Nothing in this  Article  shall
affect in any way the Investor's  obligations under any agreement to comply with
all applicable securities laws upon resale of the Common Stock.

                                    ARTICLE X

                                  CHOICE OF LAW

           Section 10.1 Choice of Law; Venue; Jurisdiction.  This Agreement will
be  construed  and enforced in  accordance  with and governed by the laws of the
State of New York,  except for matters arising under the Act, without  reference
to  principles  of  conflicts  of  law.  Each  of the  parties  consents  to the
jurisdiction of the U.S.  District Court sitting in the Southern District of the
State of New York or the  state  courts  of the  State  of New York  sitting  in
Manhattan in connection with any dispute arising under this Agreement and hereby
waives,  to the maximum extent  permitted by law, any  objection,  including any
objection based on forum non conveniens,  to the bringing of any such proceeding
in such  jurisdictions.  Each party hereby  agrees that if another party to this
Agreement  obtains a judgment  against it in such a proceeding,  the party which
obtained such judgment may enforce same by summary judgment in the courts of any
country  having  jurisdiction  over the party  against  whom such  judgment  was
obtained,  and each party hereby waives any defenses available to it under local
law and  agrees  to the  enforcement  of such a  judgment.  Each  party  to this
Agreement  irrevocably consents to the service of process in any such proceeding
by the  mailing of copies  thereof by  registered  or  certified  mail,  postage
prepaid,  to such party at its address set forth  herein.  Nothing  herein shall
affect the right of any party to serve process in any other manner  permitted by
law.

                                   ARTICLE XI

              ASSIGNMENT; ENTIRE AGREEMENT, AMENDMENT; TERMINATION

           Section 11.1 Assignment. Neither this Agreement nor any rights of the
Investor or the Company  hereunder  may be assigned by either party to any other

                                       21
<PAGE>



of this  Agreement  shall inure to the benefit  of, and be  enforceable  by, any
transferee  of any of the Common  Stock  purchased  or acquired by the  Investor
hereunder with respect to the Common Stock held by such person, and (b) upon the
prior written  consent of the Company,  which consent shall not  unreasonably be
withheld, the Investor's interest in this Agreement may be assigned at any time,
in whole or in part,  to any  affiliate  of the  Investor who agrees to make the
representations  and  warranties  contained  in Article III and who agrees to be
bound by the covenants of Article V.

           Section 11.2  Termination.  This Agreement  shall  terminate upon the
earliest of (i) the date that all the  Registrable  Securities have been sold by
the  Investors  pursuant  to the  Registration  Statement;  (ii)  the  date  the

the provisions of Articles III, IV, V, VI, VII, VIII, IX, X, XI, and XII, herein

           Either  party  hereto  may from time to time  change  its  address or
facsimile number for notices under this Section 12.1 by giving at least ten (10)
days' prior written  notice of such changed  address or facsimile  number to the
other party hereto.

           Section 12.2  Indemnification.  The Company  agrees to indemnify  and
hold  harmless the  Investor and each person,  if any, who controls the Investor
within the meaning of the Securities Act against any losses,  claims, damages or
liabilities,  joint or several (which shall, for all purposes of this Agreement,
include,  but not be limited to, all costs of defense and  investigation and all
attorneys' fees), to which the Investor may become subject, under the Securities
Act or otherwise,  insofar as such losses,  claims,  damages or liabilities  (or
actions  in  respect  thereof)  arise out of or are based upon the breach of any
term of this  Agreement.  This  indemnity  agreement  will be in addition to any
liability which the Company may otherwise have.

           Each  Investor  agrees that it will  indemnify  and hold harmless the
Company,  and each  officer,  director  of the  Company or person,  if any,  who
controls  the Company  within the  meaning of the  Securities  Act,  against any
losses,  claims,  damages or liabilities  (which shall, for all purposes of this
Agreement,   include,   but  not  be  limited  to,  all  costs  of  defense  and
investigation and all attorneys' fees) to which the Company or any such officer,
director or  controlling  person may become  subject under the Securities Act or
otherwise,  insofar as such losses claims, damages or liabilities (or actions in
respect  thereof)  arise out of or are based upon the breach of any term of this
Agreement.  This indemnity  agreement will be in addition to any liability which
the Investor or any subsequent assignee may otherwise have.

           Promptly after receipt by an indemnified  party under this Section 12
of notice of the commencement of any action,  such indemnified  party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section,  notify the  indemnifying  party of the commencement  thereof;  but the
omission so to notify the  indemnifying  party will not relieve the indemnifying
party from any liability  which it may have to any  indemnified  party otherwise
than as to the particular item as to which  indemnification is then being sought
solely pursuant to this Section.  In case any such action is brought against any
indemnified  party, and it notifies the  indemnifying  party of the commencement
thereof,  the indemnifying party will be entitled to participate in, and, to the
extent that it may wish,  jointly with any other  indemnifying  party  similarly
notified,  assume the defense thereof,  subject to the provisions  herein stated
and after notice from the indemnifying party to such indemnified party of its


                                       23
<PAGE>



election so to assume the defense thereof,  the  indemnifying  party will not be
liable to such  indemnified  party  under  this  Section  for any legal or other
expenses  subsequently incurred by such indemnified party in connection with the
defense  thereof  other  than  reasonable  costs of  investigation,  unless  the
indemnifying  party  shall not pursue the  action to its final  conclusion.  The
indemnified  party shall have the right to employ  separate  counsel in any such
action and to participate in the defense  thereof,  but the fees and expenses of
such  counsel  shall  not be at the  expense  of the  indemnifying  party if the
indemnifying party has assumed the defense of the action with counsel reasonably
satisfactory to the indemnified party; provided that if the indemnified party is
the  Investor,  the fees and expenses of such counsel shall be at the expense of
the  indemnifying  party  if  (i)  the  employment  of  such  counsel  has  been
specifically  authorized in writing by the indemnifying party, or (ii) the named
parties to any such action  (including any impleaded  parties)  include both the
Investor and the indemnifying  party and the Investor shall have been advised by
such  counsel  that there may be one or more  legal  defenses  available  to the
indemnifying  party  different from or in conflict with any legal defenses which
may be available to the Investor (in which case the indemnifying party shall not
have the right to assume the defense of such  action on behalf of the  Investor,
it being understood,  however,  that the indemnifying  party shall, in connetion
with any one such  action or  separate  but  substantially  similar  or  related
actions in the same jurisdiction  arising out of the same general allegations or
circumstances,  be  liable  only for the  reasonable  fees and  expenses  of one
separate firm of attorneys  for the Investor,  which firm shall be designated in
writing by the  Investor).  No settlement of any action  against an  indemnified
party shall be made without the prior written consent of the indemnified  party,
which consent shall not be unreasonably withheld.

           Section 12.3 Contribution. In order to provide for just and equitable
contribution  under the Securities Act in any case in which (i) the  indemnified
party makes a claim for  indemnification  pursuant to Section 12.2 hereof but is
judicially  determined (by the entry of a final judgment or decree by a court of
competent jurisdiction and the expiration of time to appeal or the denial of the
last right of appeal) that such indemnification may not be enforced in such case
notwithstanding  the fact that the  express  provisions  of Section  12.2 hereof
provide  for  indemnification  in such  case,  or (ii)  contribution  under  the
Securities Act may be required on the part of any  indemnified  party,  then the
Company and the applicable  Investor shall  contribute to the aggregate  losses,
claims,  damages or liabilities  to which they may be subject (which shall,  for
all  purposes of this  Agreement,  include,  but not be limited to, all costs of
defense and  investigation  and all attorneys' fees), in either such case (after
contribution  from  others) on the basis of relative  fault as well as any other
relevant equitable considerations.  The amount paid or payable by an indemnified
party as a result of the losses,  claims,  damages or liabilities (or actions in
respect  thereof)  referred to above in Section  12.2 shall be deemed to include
any legal or other expenses  reasonably  incurred by such  indemnified  party in
connection with  investigating  or defending any such action or claim. No person
guilty of fraudulent  misrepresentation  (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to  contributions  from any person who was
not guilty of such fraudulent misrepresentation.


                                  ARTICLE XIII

                                  MISCELLANEOUS

           Section 13.1 Counterparts;  Facsimile; Amendments. This Agreement may
be executed in multiple counterparts, each of which may be executed by less than
all of the parties and shall be deemed to be an original  instrument which shall
be enforceable  against the parties actually executing such counterparts and all
of which  together  shall  constitute  one and the same  instrument.  Except  as
otherwise  stated  herein,  in  lieu  of the  original  documents,  a  facsimile
transmission  or  copy of the  original  documents  shall  be as  effective  and
enforceable  as the  original.  This  Agreement may be amended only by a writing
executed by all parties.

Attachments hereto,  which include,  but are not limited to Warrant A and B, the
Escrow  Agreement,  and the  Registration  Rights Agreement set forth the entire

subject matter hereof.  The terms and conditions of all Exhibits and Attachments
to this Agreement are incorporated herein by this reference and shall constitute
part of this Agreement as is fully set forth herein.

           Section 13.3 Survival; Severability. The representations, warranties,
covenants  and  agreements  of the parties  hereto  shall  survive  each Closing
hereunder.  In the event  that any  provision  of this  Agreement  becomes or is
declared by a court of competent  jurisdiction to be illegal,  unenforceable  or
void,  this  Agreement  shall  continue  in full force and effect  without  said
provision; provided that such severability shall be ineffective if it materially
changes the economic benefit of this Agreement to any party.

           Section 13.4 Title and  Subtitles.  The titles and subtitles  used in
this  Agreement  are used for  convenience  only and are not to be considered in
construing or interpreting this Agreement.

           Section 13.5  Reporting  Entity for the Common  Stock.  The reporting
entity relied upon for the  determination of the trading price or trading volume
of the Common Stock on any given Trading Day for the purposes of this  Agreement
shall be Bloomberg, L.P. or any successor thereto. The written mutual consent of
the  Investor  and the Company  shall be required to employ any other  reporting
entity.

           Section  13.6  Replacement  of  Certificates.  Upon  (i)  receipt  of
evidence reasonably satisfactory to the Company of the loss, theft,  destruction
or mutilation of a certificate  representing the Put Shares and (ii) in the case
of any such loss, theft or destruction of such certificate,  upon delivery of an
indemnity  agreement or security  reasonably  satisfactory in form and amount to
the  Company  or  (iii) in the case of any such  mutilation,  on  surrender  and
cancellation  of such  certificate,  the Company at its expense will execute and
deliver, in lieu thereof, a new certificate of like tenor.

                  To Purchase ______ Shares of Common Stock of

                              XYBERNAUT CORPORATION


           THIS CERTIFIES that, for value received,  _____________________  (the
"Investor"),  is  entitled,  upon  the  terms  and  subject  to  the  conditions
hereinafter  set forth, at any time on or after October 15, 1998 and on or prior
to October 15, 2003 (the  "Termination  Date") but not thereafter,  to subscribe
for and purchase from XYBERNAUT CORPORATION,  a corporation  incorporated in the
State of Delaware (the  "Company"),  ____________  ____________  (______) shares
(the  "Warrant  Shares")  of Common  Stock,  par value US $0.01 per share of the
Company (the "Common  Stock").  The purchase  price of one share of Common Stock
(the  "Exercise  Price") under this Warrant shall be equal to $1.76 The Exercise
Price and the number of shares for which the  Warrant  is  exercisable  shall be
subject to  adjustment  as  provided  herein.  This  Warrant is being  issued in
connection  with the Private Equity Line Of Credit  Agreement  dated on or about
April 13, 1998 (the "Agreement"), and is subject to its terms and conditions. In
the event of any conflict  between the terms of this Warrant and the  Agreement,
the Agreement shall control.


<PAGE>



           1.         Title of  Warrant.  Prior  to the  expiration  hereof  and
subject  to  compliance  with  applicable  laws,  this  Warrant  and all  rights
hereunder are transferable,  in whole or in part, at the office or agency of the
Company  by the holder  hereof in person or by duly  authorized  attorney,  upon
surrender of this  Warrant  together  with the  Assignment  Form annexed  hereto
properly endorsed.

           2.         Authorization  of Shares.  The Company  covenants that all
shares  of  Common  Stock  which  may be  issued  upon the  exercise  of  rights
represented  by this Warrant will,  upon exercise of the rights  represented  by
this Warrant, be duly authorized,  validly issued,  fully paid and nonassessable
and free from all taxes,  liens and  charges  in  respect  of the issue  thereof
(other than taxes in respect of any transfer  occurring  contemporaneously  with
such issue).

                      Exercise  of  Warrant.  Except as  provided  in  Section 4
below,  exercise of the purchase rights  represented by this Warrant may be made
at any time or times,  before the close of business on the Termination  Date, or
such  earlier  date on which this  Warrant  may  terminate  as  provided in this
Warrant,  by the  surrender  of this  Warrant  and the Notice of  Exercise  Form
annexed hereto duly executed, at the office of the Company (or such other office
or agency of the  Company  as it may  designate  by  notice  in  writing  to the
registered holder hereof at the address of such holder appearing on the books of
the  Company)  and upon  payment of the  Exercise  Price of the  shares  thereby
purchased;  whereupon  the holder of this Warrant shall be entitled to receive a
certificate for the number of shares of Common Stock so purchased.  Certificates
for shares  purchased  hereunder  shall be delivered to the holder hereof within
three (3)  business  days after the date on which this  Warrant  shall have been
exercised as  aforesaid.  Payment of the Exercise  Price of the shares may be by
certified check or cashier's check or by wire transfer to an account  designated
by the Company in an amount equal to the Exercise Price multiplied by the number
of Warrant Shares.

           4.         No Fractional  Shares or Scrip.  No  fractional  shares or
scrip  representing  fractional shares shall be issued upon the exercise of this
Warrant.

           5.         Charges, Taxes and Expenses.  Issuance of certificates for
shares of Common Stock upon the  exercise of this Warrant  shall be made without
charge to the holder  hereof for any issue or transfer  tax or other  incidental
expense in respect of the issuance of such  certificate,  all of which taxes and
expenses shall be paid by the Company,  and such certificates shall be issued in
the  name of the  holder  of this  Warrant  or in such  name or  names as may be
directed by the holder of this  Warrant;  provided,  however,  that in the event
certificates  for  shares of Common  Stock are to be issued in a name other than
the name of the  holder of this  Warrant,  this  Warrant  when  surrendered  for
exercise  shall be  accompanied  by the  Assignment  Form  attached  hereto duly
executed by the holder  hereof;  and  provided  further,  that upon any transfer
involved in the  issuance or delivery of any  certificates  for shares of Common
Stock,  the Company may require,  as a condition  thereto,  the payment of a sum
sufficient to reimburse it for any transfer tax incidental thereto.


                                       2
<PAGE>



           6.         Closing  of  Books.   The  Company   will  not  close  its
shareholder books or records in any manner which prevents the timely exercise of
this Warrant for a period of time in excess of five (5) trading days per year.

           7.         No Rights as Shareholder until Exercise. This Warrant does
not  entitle  the  holder  hereof  to any  voting  rights  or other  rights as a
shareholder of the Company prior to the exercise thereof.  Upon the surrender of
this Warrant and the payment of the aggregate Exercise Price, the Warrant Shares
so  purchased  shall be and be deemed to be issued to such  holder as the record
owner of such  shares  as of the close of  business  on the later of the date of
such surrender or payment.

           8.         Assignment  and  Transfer of Warrant.  This Warrant may be
assigned by the surrender of this Warrant and the Assignment Form annexed hereto
duly  executed at the office of the  Company (or such other  office or agency of
the Company as it may  designate by notice in writing to the  registered  holder
hereof at the address of such holder appearing on the books of the Company).

           9.         Loss,  Theft,  Destruction  or Mutilation of Warrant.  The
Company  represents  and  warrants  that upon receipt by the Company of evidence
reasonably  satisfactory to it of the loss, theft,  destruction or mutilation of
this  Warrant  certificate  or any stock  certificate  relating  to the  Warrant
Shares,  and in case of loss,  theft or  destruction,  of  indemnity or security
reasonably  satisfactory  to it, and upon  surrender  and  cancellation  of such
Warrant or stock certificate,  if mutilated, the Company will make and deliver a
new  Warrant  or  stock   certificate  of  like  tenor  and  dated  as  of  such
cancellation, in lieu of such Warrant or stock certificate.

           10.        Saturdays,   Sundays,   Holidays,  etc.  If  the  last  or
appointed  day for the  taking  of any  action  or the  expiration  of any right
required or granted herein shall be a Saturday,  Sunday or a legal holiday, then
such action may be taken or such right may be exercised  on the next  succeeding
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.

           The Company  agrees that the Warrant  Shares shall be included in the
Registration Statement to be filed by the Company pursuant to the Private Equity
Line Of Credit Agreement dated as of April 13, 1998.



                                       3
<PAGE>



           12.        Adjustments  of  Exercise  Price  and  Number  of  Warrant
Shares. The number and kind of securities  purchasable upon the exercise of this
Warrant and the Exercise Price shall be subject to adjustment  from time to time
upon the happening of any of the following.

           In case the Company  shall (i) declare or pay a dividend in 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 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.        Call/Forced  Exercise.  The  Company,  at its option,  may
redeem this  Warrant for $0.01 per  Warrant  Share by giving the Holder  written
notice  (the "Call  Notice")  at any time after the  Registration  Statement  is
declared effective, and the closing Bid Price of the Common Stock of the Company
is greater than


                                       4
<PAGE>



one  hundred  fifty  (150%)  percent  of the  Exercise  Price  for  twenty  (20)
consecutive Trading Days. To be effective,  the Call Notice must be given within
three (3) Trading Days after the  aforementioned  twenty day period.  The rights
and privileges granted pursuant to this Warrant shall terminate thirty (30) days
after the Call  Notice is sent to the  Holder if the  warrant  is not  exercised
during that  period.  In the event the Warrants  are not  exercised  during this
period the Company  will remit to the Holder  $0.01 per  Warrant  Share upon the
Holder tendering to the Company the expired Warrant certificate.

           17.        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

      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.

           (d)        Notices. Any notice, request or other document required or
permitted to be given or delivered to the holders hereof by the Company shall be
delivered or shall be sent by certified or registered mail, postage prepaid,  to
each such  holder at its  address as shown on the books of the Company or to the
Company at the address set forth in the Agreement.

           IN  WITNESS  WHEREOF,  the  Company  has  caused  this  Warrant to be
executed by its officer thereunto duly authorized.

            1.    Title of Warrant.  Prior to the expiration  hereof and subject
to compliance  with applicable  laws, this Warrant and all rights  hereunder are
transferable, in whole or in part, at the office or agency of the Company by the
holder hereof in person or by duly authorized  attorney,  upon surrender of this
Warrant together with the Assignment Form annexed hereto properly endorsed.

            2.    Authorization of Shares. The Company covenants that all shares
of Common Stock which may be issued upon the exercise of rights  represented  by
this Warrant will, upon exercise of the rights  represented by this Warrant,  be
duly authorized,  validly issued, fully paid and nonassessable and free from all
taxes,  liens and charges in respect of the issue  thereof  (other than taxes in
respect of any transfer occurring contemporaneously with such issue).

            Exercise of Warrant. Except as provided in Section 4 below, exercise
of the purchase  rights  represented  by this Warrant may be made at any time or
times,  before the close of business on the  Termination  Date,  or such earlier
date on which this  Warrant may  terminate as provided in this  Warrant,  by the
surrender  of this Warrant and the Notice of Exercise  Form annexed  hereto duly
executed,  at the office of the Company  (or such other  office or agency of the
Company as it may designate by notice in writing to the registered holder hereof
at the address of such holder  appearing  on the books of the  Company) and upon
payment of the Exercise  Price of the shares  thereby  purchased;  whereupon the
holder of this Warrant shall be entitled to receive a certificate for the number
of  shares of Common  Stock so  purchased.  Certificates  for  shares  purchased
hereunder shall be delivered to the holder hereof within three (3) business days
after the date on which this Warrant  shall have been  exercised  as  aforesaid.
Payment  of the  Exercise  Price  of the  shares  may be by  certified  check or
cashier's  check or by wire transfer to an account  designated by the Company in
an amount  equal to the  Exercise  Price  multiplied  by the  number of  Warrant
Shares.

            4.    No Fractional  Shares or Scrip. No fractional  shares or scrip
representing  fractional  shares  shall  be  issued  upon the  exercise  of this
Warrant.

            5.    Charges,  Taxes and  Expenses.  Issuance of  certificates  for
shares of Common Stock upon the  exercise of this Warrant  shall be made without
charge to the holder  hereof for any issue or transfer  tax or other  incidental
expense in respect of the issuance of such  certificate,  all of which taxes and
expenses shall be paid by the Company,  and such certificates shall be issued in
the  name of the  holder  of this  Warrant  or in such  name or  names as may be
directed by the holder of this  Warrant;  provided,  however,  that in the event
certificates  for  shares of Common  Stock are to be issued in a name other than
the name of the  holder of this  Warrant,  this  Warrant  when  surrendered  for
exercise  shall be  accompanied  by the  Assignment  Form  attached  hereto duly
executed by the holder  hereof;  and  provided  further,  that upon any transfer
involved in the  issuance or delivery of any  certificates  for shares of Common
Stock,  the Company may require,  as a condition  thereto,  the payment of a sum
sufficient to reimburse it for any transfer tax incidental thereto.

            6.    Closing of Books.  The Company will not close its  shareholder
books or records in any  manner  which  prevents  the  timely  exercise  of this
Warrant for a period of time in excess of five (5) trading days per year.

            7.    No Rights as Shareholder until Exercise. This Warrant does not
entitle the holder  hereof to any voting rights or other rights as a shareholder
of the Company prior to the exercise thereof. Upon the surrender of this Warrant
and the payment of the aggregate Exercise Price, the Warrant Shares so purchased
shall be and be deemed to be issued to such  holder as the record  owner of such
shares as of the close of business on the later of the date of such surrender or
payment.

            8.    Assignment  and  Transfer  of  Warrant.  This  Warrant  may be
assigned by the surrender of this Warrant and the Assignment Form annexed hereto
duly  executed at the office of the  Company (or such other  office or agency of
the Company as it may  designate by notice in writing to the  registered  holder
hereof at the address of such holder appearing on the books of the Company).

            9.    Loss, Theft, Destruction or Mutilation of Warrant. The Company
represents and warrants that upon receipt by the Company of evidence  reasonably
satisfactory to it of the loss, theft, destruction or mutilation of this Warrant
certificate or any stock certificate relating to the Warrant Shares, and in case
of loss, theft or destruction,  of indemnity or security reasonably satisfactory
to it, and upon surrender and cancellation of such Warrant or stock certificate,
if  mutilated,  the  Company  will  make  and  deliver  a new  Warrant  or stock
certificate  of like  tenor and dated as of such  cancellation,  in lieu of such
Warrant or stock certificate.

            10.   Saturdays,  Sundays,  Holidays,  etc. If the last or appointed
day for the  taking of any action or the  expiration  of any right  required  or
granted herein shall be a Saturday,  Sunday or a legal holiday, then such action
may be taken or such right may be  exercised  on the next  succeeding  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.

                  The Company  agrees that the Warrant  Shares shall be included
in the Registration Statement to be filed by the Company pursuant to the Private
Equity Line Of Credit Agreement dated on or about April 13, 1998.

            12.   Adjustments  of Exercise  Price and Number of Warrant  Shares.
The number and kind of securities  purchasable upon the exercise of this Warrant
and the Exercise Price shall be subject to adjustment from time to time upon the
happening of any of the following.

            In case the Company shall (i) declare or pay a dividend in 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 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.   Call/Forced  Exercise.  The Company, at its option, may redeem
this  Warrant for $0.01 per Warrant  Share by giving the Holder  written  notice
(the "Call  Notice") at any time after the  Registration  Statement  is declared
effective,  and the  closing  bid price of the  Common  Stock of the  Company is
greater than one hundred fifty (150%)  percent of the Exercise  Price for twenty
(20)  consecutive  Trading Days. To be effective,  the Call Notice must be given
within three (3) days after the aforementioned twenty day period. The rights and
privileges  granted  pursuant to this Warrant shall  terminate  thirty (30) days
after the Call  Notice is sent to the  Holder if the  warrant  is not  exercised
during that  period.  In the event the Warrants  are not  exercised  during this
period the Company  will remit to the Holder  $0.01 per  Warrant  Share upon the
Holder tendering to the Company the expired Warrant certificate.

            17.   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.

            (d)   Notices.  Any notice,  request or other  document  required or
permitted to be given or delivered to the holders hereof by the Company shall be
delivered or shall be sent by certified or registered mail, postage prepaid,  to
each such  holder at its  address as shown on the books of the Company or to the
Company at the address set forth in the Agreement.

            IN  WITNESS  WHEREOF,  the  Company  has caused  this  Warrant to be
executed by its officer thereunto duly authorized.

Xybernaut Corporation

Fairfax, Virginia 22033

Gentlemen:

            We have  acted as  counsel  to  Xybernaut  Corporation,  a  Delaware
corporation  (the "Company"),  in connection with the Registration  Statement on
Form S-3 (the  "Registration  Statement")  being filed with the  Securities  and
Exchange  Commission  under the Securities Act of 1933, as amended,  relating to
the offering of 2,340,938  shares (the "Shares") of Common Stock, par value $.01
per share (the "Common Stock") of the Company.

            Capitalized  terms  used  herein  and not  defined  shall  have  the
meanings given to them in the Registration Statement.

            In connection  with the  foregoing,  we have  examined  originals or
copies,  satisfactory to us, of the Company's (i) Certificate of  Incorporation,
(ii) By-laws and (iii) resolutions of the Company's board of directors.  We have
also  reviewed  such other  matters of law and examined and relied upon all such
corporate  records,  agreements,  certificates  and other  documents  as we have
deemed relevant and necessary as a basis for the opinion hereinafter  expressed.
In such  examination,  we have assumed the  genuineness of all  signatures,  the
authenticity  of all documents  submitted to us as originals and the  conformity
with the  original  documents  of all  documents  submitted  to us as  copies or
facsimiles.  As to any facts  material to such  opinion,  we have, to the extent
that  relevant  facts  were  not  independently  established  by us,  relied  on
certificates  of  public   officials  and  certificates  of  officers  or  other
representatives of the Company.

            Based upon and subject to the foregoing,  we are of the opinion that
the Shares,  when issued  pursuant  to the terms and  conditions  of the Private
Equity Line Credit  Agreement,  Warrant A, Warrant B and the Put Options will be
validly issued, fully paid and non-assessable.

                          REGISTRATION RIGHTS AGREEMENT

            THIS  REGISTRATION  RIGHTS  AGREEMENT,  dated  as of the 13th day of
April,  1998, among the entities listed on Schedule A (collectively  referred to
as the  "Investors"),  Settondown  Capital  International  Ltd. (the  "Placement
Agent",  along with the Investor also referred to as the  "Holders")  located at
Charlotte  House,  Charlotte  Street,  P.O. Box N. 9204,  Nassau,  Bahamas,  and
XYBERNAUT CORPORATION, a corporation incorporated under the laws of the state of
Delaware, and having its principle place of business at 12701 Fair Lakes Circle,
Suite 550, Fairfax, Virginia 22033 (the "Company").

            WHEREAS, the Investors are purchasing from the Company,  pursuant to
a Private  Equity Line of Credit  Agreement  dated the date hereof (the  "Equity
Line  Agreement"),  an aggregate of up to Eleven Million  ($11,000,000)  Dollars
principal  amount  of shares of Common  Stock  $0.01 par  value,  a Warrant A to
purchase  20,000  shares  of the  Company's  Common  Stock,  and a  Warrant B to
purchase  20,000  shares of the  Company's  Common  Stock (plus such  additional
shares of Common Stock as set forth in the Equity Line Agreement); and

            WHEREAS,  the Company shall issue to the Placement  Agent, in return
for services rendered,  the following  securities:  (a) upon the Closing for the
Initial Shares, (i) up to 50,000 shares of Common Stock (restricted as set forth
in  Section  13.7 (i) of the  Equity  Line  Agreement),  and (ii) a Warrant A to
purchase  20,000 shares of Common  Stock;  and (b) upon the Closing of each Put,
five (5%) percent of that number of Put Shares issued on the Closing of each Put
(which shall not be included in the definition of Registrable Securities below);
and

            WHEREAS,   the   Company   desires  to  grant  to  the  Holders  the
registration  rights set forth herein with respect to the shares of Common Stock
and  shares  of  Common  Stock  underlying  both  Warrants  A and B  (plus  such
additional  shares of Common Stock issuable  pursuant to the terms of the Equity
Line  Agreement,   collectively  hereinafter  referred  to  as  the  "Stock"  or
"Securities"  of the Company).  All  capitalized  terms not defined herein shall
have that meaning as set forth in the Equity Line Agreement.

            NOW, THEREFORE, the parties hereto mutually agree as follows:

            Section  1.  Registrable   Securities.   As  used  herein  the  term
"Registrable  Security"  means  the  Securities;  provided,  however,  that with
respect to any particular Registrable Security,  such security shall cease to be
a Registrable  Security when, as of the date of  determination,  (i) it has been
effectively  registered  under the Securities Act of 1933, as amended (the "1933
Act") and disposed of pursuant thereto,  (ii) registration under the 1933 Act is
no longer required for the immediate  public  distribution of such security as a
result of the provisions of Rule 144 promulgated under the 1933 Act, or (iii) it
has ceased to be outstanding. The term "Registrable Securities" means any and/or
all of the securities falling within the foregoing  definition of a "Registrable
Security."   In  the  event  of  any  merger,   reorganization,   consolidation,
recapitalization  or other change in corporate  structure  affecting  the Common
Stock, such adjustment shall be made in the definition of "Registrable Security"
as is  appropriate in order to prevent any dilution or enlargement of the rights
granted pursuant to this Section 1.

            Section 2.  Restrictions  on Transfer.  The Holders  acknowledge and
understand that prior to the  registration of the Securities as provided herein,
the Securities are "restricted securities" as defined in Rule 144




<PAGE>



promulgated  under  the Act.  The  Holders  understand  that no  disposition  or
transfer of the  Securities  may be made by the Holders in the absence of (i) an
opinion  of  counsel  to the  Holders  that such  transfer  may be made  without
registration under the 1933 Act or (ii) such  registration.  The Placement Agent
agrees that the shares of Common Stock it shall receive on the Subscription Date
shall be subject to a one-year lock up following the Subscription Date.

            Section 3. Registration Rights.

                        (a)   The Company  agrees that it will  prepare and file
with the Securities and Exchange Commission  ("Commission"),  within thirty (30)
days after the Subscription  Date, a registration  statement (on Form S-3) under
the 1933 Act (the "Registration Statement"),  at the sole expense of the Company
(except  as  provided  in Section  3(c)  hereof),  in respect of all  holders of
Registrable  Securities,  so as to permit a resale of the Registrable Securities
under the Act.

                        The  Company  shall  use its best  efforts  to cause the
Registration  Statement  to become  effective  within  ninety (90) days from the
Subscription Date. The number of shares designated in the Registration Statement
to be registered  shall be the total of: (i) one hundred fifty (150%) percent of
the number of Initial  Shares;  (ii) one hundred (100%) percent of the number of
Warrant  Shares  if  they  were  issued  on the day  before  the  filing  of the
Registration  Statement;  and (iii) such additional  number of Put Shares deemed
reasonably necessary by the Company.

                        (b)   The Company will  maintain the  effectiveness  the
Registration  Statement or  post-effective  amendment filed under this Section 3
hereof  current under the 1933 Act until the earlier of (i) the date that all of
the  Registrable   Securities  have  been  sold  pursuant  to  the  Registration
Statement,  (ii) the date the holders thereof receive an opinion of counsel that
all of the  Registrable  Securities may be sold under the provisions of Rule 144
or (iii) five and one half years after the Subscription Date.

                        (c)   All fees, disbursements and out-of-pocket expenses
and costs incurred by the Company in connection  with the preparation and filing
of the  Registration  Statement  under  subparagraph  3(a) and in complying with
applicable  securities and Blue Sky laws  (including,  without  limitation,  all
attorneys'  fees) shall be borne by the Company.  The Holder shall bear the cost
of underwriting discounts and commissions, if any, applicable to the Registrable
Securities  being  registered  and the fees and  expenses  of its  counsel.  The
Company  shall  qualify  any of the  securities  for sale in such states as such
Holder  reasonably  designates and shall furnish  indemnification  in the manner
provided  in Section 6 hereof.  However,  the  Company  shall not be required to
qualify any of the securities for sale in any state which will require an escrow
or other restriction  relating to the Company and/or the sellers. The Company at
its expense will supply the Holder with copies of the Registration Statement and
the prospectus or offering circular included therein and other related documents
in such quantities as may be reasonably requested by the Holder.

                        (d)   The Company  shall not be required by this Section
3 to include a Holder's  Registrable  Securities in any  Registration  Statement
which is to be filed if, in the  opinion of counsel for both the Holders and the
Company  (or,  should  they  not  agree,  in  the  opinion  of  another  counsel
experienced in securities law matters  acceptable to counsel for the Holders and
the  Company)  the  proposed  offering  or  other  transfer  as  to  which  such
registration is requested is exempt from applicable federal and state securities
laws and would result in all Investors or transferees obtaining securities which
are not "restricted securities", as defined in Rule 144 under the 1933 Act.

                        (e)   In the  event  the  Registration  Statement  to be
filed by the  Company  pursuant  to  Section  3(a)  above is not filed  with the
Commission  within  thirty  (30)  days from the  Subscription  Date  and/or  the
Registration Statement is not declared effective by the Commission within ninety
(90) days from the  Subscription  Date,  then the  Company  will pay Holder (pro
rated on a daily  basis),  as  liquidated  damages for such failure and not as a
penalty,  two  (2%)  percent  of the  Purchase  Price  of the  then  outstanding
Securities for every thirty (30) day period  thereafter  until the  Registration
Statement  has  been  filed  and/or  declared  effective.  Such  payment  of the
liquidated  damages  shall  be made to the  Holders  in cash,  immediately  upon
demand, provided, however, that the payment of such liquidated damages shall not
relieve the Company from its obligations to register the Securities  pursuant to
this Section.

                        If the Company does not remit the damages to the Holders
as set forth  above,  the  Company  will pay the  Holders'  reasonable  costs of
collection, including attorneys fees, in addition to the liquidated damages. The
registration  of the Securities  pursuant to this provision  shall not affect or
limit Holders' other rights or remedies as set forth in this Agreement.

                        (f)   No provision  contained  herein shall preclude the
Company from selling securities pursuant to any Registration  Statement in which
it is required to include Registrable Securities pursuant to this Section 3.

                        (g)   If at any  time or from  time  to time  after  the
effective date of the Registration  Statement,  the Company notifies the Holders
in writing of the existence of a Potential Material Event (as defined in Section
3(h) below),  the Holders shall not offer or sell any Registrable  Securities or
engage in any other transaction involving or relating to Registrable Securities,
from the time of the giving of notice with respect to a Potential Material Event
until such Holder  receives  written notice from the Company that such Potential
Material Event either has been disclosed to the public or no longer  constitutes
a  Potential  Material  Event;  provided,  however,  that the Company may not so
suspend  the right to such  holders of  Securities  for more than one (1) twenty
(20) day period in the  aggregate  during any twelve  month  period,  during the
periods the Registration  Statement is required to be in effect.  If a Potential
Material  Event  shall  occur prior to the date the  Registration  Statement  is
filed, then the Company's obligation to file the Registration Statement shall be
delayed  without  penalty for not more than twenty (20) days.  The Company  must
give each Holder  notice in writing at least two (2) business  days prior to the
first day of the blackout period.

                        (h)   "Potential   Material  Event"  means  any  of  the
following:  (a) the possession by the Company of material  information  not ripe
for disclosure in a registration  statement;  or (b) any material  engagement or
activity by the Company  which would be adversely  affected by  disclosure  in a
registration  statement at such time, that the  Registration  Statement would be
materially misleading absent the inclusion of such information.

            Section 4. Cooperation with Company. Holders will cooperate with the
Company in all respects in  connection  with this  Agreement,  including  timely
supplying all information  reasonably requested by the Company and executing and
returning all documents reasonably requested in connection with the registration
and sale of the Registrable Securities.

            Section 5. Registration  Procedures.  If and whenever the Company is
required by any of the provisions of this  Agreement to effect the  registration
of any of the Registrable Securities under the Act, the Company shall (except as
otherwise provided in this Agreement), as expeditiously as possible:




                                       3
<PAGE>



                        (a)   prepare   and  file  with  the   Commission   such
amendments and supplements to the Registration Statement and the prospectus used
in connection therewith as may be necessary to keep such registration  statement
effective and to comply with the  provisions of the Act with respect to the sale
or other disposition of all securities  covered by such  registration  statement
whenever the Holder of such securities shall desire to sell or otherwise dispose
of the same  (including  prospectus  supplements  with  respect  to the sales of
securities  from  time to  time  in  connection  with a  registration  statement
pursuant to Rule 415 promulgated under the Act);

                        (b)   furnish to each Holder such numbers of copies of a
summary  prospectus or other prospectus,  including a preliminary  prospectus or
any  amendment  or  supplement  to  any  prospectus,   in  conformity  with  the
requirements of the Act, and such other documents, as such Holder may reasonably
request in order to  facilitate  the  public  sale or other  disposition  of the
securities owned by such Holder;

                        (c)   register and qualify the securities covered by the
Registration  Statement  under  such other  securities  or blue sky laws of such
jurisdictions  as  the  Holders  shall   reasonably   request  (subject  to  the
limitations set forth in Section 3(d) above),  and do any and all other acts and
things which may be  necessary or advisable to enable each Holder to  consummate
the public sale or other  disposition  in such  jurisdiction  of the  securities
owned by such Holder,  except that the Company shall not for any such purpose be
required to qualify to do business as a foreign  corporation in any jurisdiction
wherein it is not so qualified or to file therein any general consent to service
of process;

                        (d)   list such securities on the NASDAQ Small Cap Stock
Market or other  national  securities  exchange on which any  securities  of the
Company are then listed,  if the listing of such  securities  is then  permitted
under the rules of such exchange or NASDAQ;

                        (e)   notify  each  Holder  of  Registrable   Securities
covered by the Registration  Statement,  at any time when a prospectus  relating
thereto covered by the Registration  Statement is required to be delivered under
the Act, of the  happening of any event of which it has knowledge as a result of
which the prospectus included in the Registration  Statement, as then in effect,
includes  an untrue  statement  of a material  fact or omits to state a material
fact required to be stated therein or necessary to make the  statements  therein
not misleading in the light of the circumstances then existing.

            Section 6. Indemnification.

                        (a)   The Company  agrees to indemnify and hold harmless
the Holders and each person, if any, who controls each Holder within the meaning
of the 1933 Act ("Distributing  Holder") against any losses,  claims, damages or
liabilities,  joint or several (which shall, for all purposes of this Agreement,
include,  but not be limited to, all costs of defense and  investigation and all
attorneys' fees), to which the Distributing Holder may become subject, under the
1933 Act or otherwise,  insofar as such losses,  claims,  damages or liabilities
(or  actions  in  respect  thereof)  arise out of or are based  upon any  untrue
statement or alleged  untrue  statement of any  material  fact  contained in the
Registration Statement, or any related preliminary prospectus, final prospectus,
offering circular, notification or amendment or supplement thereto, or arise out
of or are  based  upon the  omission  or  alleged  omission  to state  therein a
material fact required to be stated  therein or necessary to make the statements
therein  not  misleading;  provided,  however,  that the Company (i) will not be
liable in any such  case to the  extent  that any such  loss,  claim,  damage or
liability  arises out of or is based upon an untrue  statement or alleged untrue
statement or omission or alleged  omission made in the  Registration  Statement,
preliminary




                                       4
<PAGE>



prospectus,  final prospectus,  offering circular,  notification or amendment or
supplement thereto in reliance upon, and in conformity with, written information
furnished to the Company by the Distributing Holder, specifically for use in the
preparation  thereof,  or (ii) cannot pay any amounts paid in  settlement of any
loss,  claim,  damage or liability if such  settlement  is effected  without the
consent of the Company, which consent shall not be unreasonably  withheld.  This
Section  6(a) shall not inure to the  benefit of any  Distributing  Holder  with
respect to any  person  asserting  such loss,  claim,  damage or  liability  who
purchased  the  Registrable  Securities  which are the  subject  thereof  if the
Distributing  Holder  failed to send orgive (in violation of the 1933 Act or the
rules and regulations promulgated thereunder) a copy of the prospectus contained
in such  Registration  Statement  to such  person  at or  prior  to the  written
confirmation of such person of the sale of such  Registrable  Securities,  where
the  Distributing  Holder was obligated to do so under the 1933 Act or the rules
and  regulations  promulgated  thereunder.  This indemnity  provision will be in
addition to any liability which the Company may otherwise have.

                        (b)   Each  Distributing  Holder  agrees  that  it  will
indemnify  and hold  harmless the  Company,  and each  officer,  director of the
Company or person,  if any, who  controls the Company  within the meaning of the
1933 Act, against any losses,  claims,  damages or liabilities (which shall, for
all  purposes of this  Agreement,  include,  but not be limited to, all costs of
defense and  investigation  and all attorneys' fees) to which the Company or any
such officer,  director or controlling  person may become subject under the 1933
Act or otherwise,  insofar as such losses  claims,  damages or  liabilities  (or
actions in respect thereof); arise out of or are based upon any untrue statement
or alleged untrue  statement of any material fact contained in the  Registration
Statement,  or any related preliminary  prospectus,  final prospectus,  offering
circular,  notification or amendment or supplement  thereto,  or arise out of or
are based upon the omission or the alleged  omission to state therein a material
fact required to be stated therein or necessary to make the  statements  therein
not misleading,  but in each case only to the extent that such untrue  statement
or alleged  untrue  statement  or omission or alleged  omission  was made in the
Registration  Statement,  preliminary  prospectus,  final  prospectus,  offering
circular,  notification or amendment or supplement thereto in reliance upon, and
in  conformity  with,  written  information  furnished  to the  Company  by such
Distributing  Holder,  specifically  for use in the  preparation  thereof.  This
indemnity  provision will be in addition to any liability which the Distributing
Holder may otherwise have.

                        (c)   Promptly  after  receipt by an  indemnified  party
under  this  Section  6 of  notice  of  the  commencement  of any  action,  such
indemnified  party will, if a claim in respect thereof is to be made against the
indemnifying  party under this Section 6, notify the  indemnifying  party of the
commencement  thereof; but the omission so to notify the indemnifying party will
not relieve the  indemnifying  party from any liability which it may have to any
indemnified  party  otherwise  than  as to  the  particular  item  as  to  which
indemnification  is then being sought solely pursuant to this Section 6. In case
any such action is brought  against any indemnified  party,  and it notifies the
indemnifying party of the commencement  thereof,  the indemnifying party will be
entitled to  participate  in, and, to the extent that it may wish,  jointly with
any other  indemnifying  party similarly  notified,  assume the defense thereof,
subject to the provisions  herein stated and after notice from the  indemnifying
party to such  indemnified  party  of its  election  so to  assume  the  defense
thereof,  the indemnifying  party will not be liable to such  indemnified  party
under this Section 6 for any legal or other  expenses  subsequently  incurred by
such  indemnified  party in  connection  with the  defense  thereof  other  than
reasonable  costs of  investigation,  unless the  indemnifying  party  shall not
pursue the action to its final conclusion.  The indemnified party shall have the
right to employ  separate  counsel in any such action and to  participate in the
defense  thereof,  but the fees and expenses of such counsel shall not be at the
expense of the  indemnifying  party if the  indemnifying  party has  assumed the
defense of the action with counsel  reasonably  satisfactory  to the indemnified
party;  provided that if the indemnified party is the Distributing  Holder,  the
fees and  expenses of such counsel  shall be at the expense of the  indemnifying
party if (i) the employment of such counsel has been specifically  authorized in
writing by the



                                       5
<PAGE>



indemnifying  party, or (ii) the named parties to any such action (including any
impleaded  parties)  include both the  Distributing  Holder and the indemnifying
party and the  Distributing  Holder shall have been advised by such counsel that
there may be one or more legal  defenses  available  to the  indemnifying  party
different  from or in conflict with any legal defenses which may be available to
the Distributing Holder (in which case the indemnifying party shall not have the
right to assume the defense of such action on behalf of the Distributing Holder,
it being undertood,  however,  that the indemnifying  party shall, in connection
with any one such  action or  separate  but  substantially  similar  or  related
actions in the same jurisdiction  arising out of the same general allegations or
circumstances,  be  liable  only for the  reasonable  fees and  expenses  of one
separate  firm of attorneys  for the  Distributing  Holder,  which firm shall be
designated in writing by the Distributing  Holder).  No settlement of any action
against an indemnified  party shall be made without the prior written consent of
the indemnified party, which consent shall not be unreasonably withheld.

            Section 7. Contribution.  In order to provide for just and equitable
contribution  under the 1933 Act in any case in which (i) the indemnified  party
makes a claim for indemnification pursuant to Section 6 hereof but is judicially
determined  (by the entry of a final  judgment or decree by a court of competent
jurisdiction  and the  expiration  of time to appeal  or the  denial of the last
right of appeal)  that such  indemnification  may not be  enforced  in such case
notwithstanding the fact that the express provisions of Section 6 hereof provide
for indemnification in such case, or (ii) contribution under the 1933 Act may be
required  on the  part  of any  indemnified  party,  then  the  Company  and the
applicable Distributing Holder shall contribute to the aggregate losses, claims,
damages  or  liabilities  to which  they may be subject  (which  shall,  for all
purposes of this Agreement, include, but not be limited to, all costs of defense
and  investigation  and  all  attorneys'  fees),  in  either  such  case  (after
contribution  from  others) on the basis of relative  fault as well as any other
relevant  equitable  considerations.  The relative  fault shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged  omission to state a material fact
relates to information supplied by the Company on the one hand or the applicable
Distributing  Holder  on the  other  hand,  and the  parties'  relative  intent,
knowledge,  access to  information  and  opportunity  to correct or prevent such
statement or  omission.  The Company and the  Distributing  Holder agree that it
would not be just and equitable if contribution  pursuant to this Section 7 were
determined by pro rata  allocation  or by any other method of  allocation  which
does  not take  account  of the  equitable  considerations  referred  to in this
Section 7. The amount paid or payable by an indemnified party as a result of the
losses,  claims, damages or liabilities (or actions in respect thereof) referred
to above in this Section 7 shall be deemed to inclue any legal or other expenses
reasonably  incurred by such indemnified party in connection with  investigating
or  defending  any  such  action  or  claim.  No  person  guilty  of  fraudulent
misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be
entitled to  contribution  from any person who was not guilty of such fraudulent
misrepresentation.

            Section  8.  Notices.  All  notices,  demands,  requests,  consents,
approvals,  and other communications required or permitted hereunder shall be in
writing and, unless otherwise specified herein,  shall be (i) personally served,
(ii) deposited in the mail,  registered or certified,  return receipt requested,
postage  prepaid,  (iii) delivered by reputable air courier service with charges
prepaid, or (iv) transmitted by hand delivery, telegram, or facsimile, addressed
as set forth below or to such other  address as such party shall have  specified
most recently by written notice. Any notice or other  communication  required or

transmitting  facsimile  machine,  at the address or number designated below (if
delivered on a business day during normal business hours where such notice is to

the benefit of the parties  hereto and their  respective  heirs,  successors and
permitted assigns.  The rights granted the Holder under this Agreement shall not
be assigned without the written consent of the Company,  which consent shall not
be  unnecessarily  withheld.  In the event of a transfer  of the rights  granted

            Section 10. Counterparts;  Facsimile; Amendments. This Agreement may
be executed in multiple counterparts, each of which may be executed by less than
all of the parties and shall be deemed to be an original  instrument which shall
be enforceable  against the parties actually executing such counterparts and all
of which  together  shall  constitute  one and the same  instrument.  Except  as
otherwise  stated  herein,  in  lieu  of the  original  documents,  a  facsimile
transmission  or  copy of the  original  documents  shall  be as  effective  and
enforceable  as the  original.  This  Agreement may be amended only by a writing
executed by all parties.

            Section 11.  Termination of Registration  Rights. The rights granted
pursuant to this  Agreement  shall  terminate  as to each Holder (and  permitted
transferees or assignees) upon the occurrence of any of the following:

            (a)   all Holder's  Securities  subject to this  Agreement have been
registered;

            (b)   all of such Holder's  Securities subject to this Agreement may
be sold without such  registration  pursuant to Rule 144  promulgated by the SEC
pursuant to the Securities Act;

            (c)   all of such Holder's  Securities subject to this Agreement can
be sold pursuant to Rule 144(k).

            Section  12.  Headings.  The  headings  in  this  Agreement  are for
reference  purposes  only  and  shall  not  affect  in any  way the  meaning  or
interpretation of this Agreement.

            Section 13. Governing Law: Venue; Jurisdiction.  This Agreement will
be  construed  and enforced in  accordance  with and governed by the laws of the
State of New York,  except for matters arising under the Act, without  reference
to  principles  of  conflicts  of  law.  Each  of the  parties  consents  to the
jurisdiction of the U.S.  District Court sitting in the Southern District of the
State of New York or the  state  courts  of the  State  of New York  sitting  in
Manhattan in connection with any dispute arising under this Agreement and hereby
waives,  to the maximum extent  permitted by law, any  objection,  including any
objection based on forum non conveniens,  to the bringing of any such proceeding
in such  jurisdictions.  Each party hereby  agrees that if another party to this
Agreement  obtains a judgment  against it in such a proceeding,  the party which
obtained such judgment may enforce same by summary judgment in the courts of any
country  having  jurisdiction  over the party  against  whom such  judgment  was

            3.3   This  Agreement  shall be binding  upon and shall inure to the
benefit of the permitted successors and assigns of the parties hereto.

            3.4   This  Agreement is the final  expression  of, and contains the
entire Agreement between,  the parties with respect to the subject matter hereof
and supersedes all prior understandings with respect thereto. This Agreement may
not be modified,  changed,  supplemented or terminated,  nor may any obligations
hereunder be waived,  except by written  instrument  signed by the parties to be
charged or by its agent duly  authorized  in writing or as  otherwise  expressly
permitted herein.

            3.5   Whenever  required  by the  context  of  this  Agreement,  the
singular shall include the plural and masculine shall include the feminine. This
Agreement  shall  not be  construed  as if it had  been  prepared  by one of the
parties,  but rather as if both parties had prepared the same.  Unless otherwise
indicated, all references to Articles are to this Agreement.

            3.6   The Company  acknowledges  and  confirms  that it is not being
represented in a legal  capacity by Goldstein,  Goldstein & Reis, LLP and it has

be governed by,  interpreted under and construed and enforced in accordance with
the laws of the State of New York . Any action to enforce,  existing  out of, or
relating in any way to, any provisions of this Agreement  shall brought  through
the American  Arbitration  Association at the designated locale of New York, New

            3.8   This Agreement may be altered or amended only with the consent
of all of the parties hereto.  Should the Company or Investor  attempt to change
this  Agreement in a manner which,  in the Escrow Agent's  discretion,  shall be
undesirable,  the  Escrow  Agent may  resign as Escrow  Agent by  notifying  the
Company  and  the  Investor  in  writing.  In the  case  of the  Escrow  Agent's
resignation or removal  pursuant to the foregoing,  its only duty, until receipt
of notice from the Company and the Investor or its agent that a successor escrow
agent shall have been appointed,  shall be to hold and preserve the funds.  Upon
receipt by the Escrow  Agent of said notice from the Company and the Investor of
the appointment of a successor escrow agent, the name of a

successor escrow account and a direction to transfer the funds, the Escrow Agent
shall  promptly  thereafter  transfer  all of the  funds  held in escrow to said
successor escrow agent.  Immediately after said transfer, the Escrow Agent shall
furnish the Company and the  Investor  with proof of such  transfer.  The Escrow
Agent is authorized to disregard any notices, requests,  instructions or demands
received by it from the Company or the Investor  after notice of  resignation or
removal  shall have been  given,  unless  the same  shall be the  aforementioned
notice from the Company  and the  Investor to transfer  the funds to a successor
escrow agent or to return same to the respective parties.

            3.9   The Escrow  Agent shall be  reimbursed  by the Company and the
Investor for any reasonable  expenses  incurred in the event there is a conflict
between  the  parties and the Escrow  Agent  shall deem it  necessary  to retain
counsel.

            3.10  The Escrow  Agent shall not be liable for any action  taken or
omitted by it in good faith in accordance  with the advice of the Escrow Agent's
counsel;  and in no event shall the Escrow Agent be liable or responsible except
for the Escrow Agent's own gross negligence or willful misconduct.

            3.11  The  Company and the  Investors  warrant to and agree with the
Escrow Agent that, unless otherwise expressly set forth in this Agreement:

                  (i) there is no  security  interest in the  Securities  or any
                  part thereof;

                  (ii) no financing  statement under the Uniform Commercial Code
                  is on file in any jurisdiction claiming a security interest or
                  in  describing   (whether   specifically   or  generally)  the
                  Securities or any part thereof; and

                  (iii) the Escrow  Agent  shall have no  responsibility  at any
                  time to ascertain  whether or not any security interest exists
                  in the Securities or any part thereof or to file any financing
                  statement  under the Uniform  Commercial  Code with respect to
                  the Securities or any part thereof.

            3.12  The  Escrow  Agent in its  capacity  as such has no  liability
hereunder to either party other than to hold the funds and the Securities and to
deliver them under the terms  hereof.  Each party hereto agrees to indemnify and
hold  harmless the Escrow Agent in its capacity as such from and with respect to
any  suits,  claims,  actions  or  liabilities  arising  in any  way out of this
transaction including the obligation to defend any legal action brought which in
any way arises out of or is related to this Escrow.
