PROSPECTUS
                        1,285,713 Shares of Common Stock*
                           (par value $.01 per share)

                              XYBERNAUT CORPORATION

           This  Prospectus  pertains to the offer and sale from time to time of
up to 1,285,713  shares (the "Shares") of common stock, par value $.01 per share
(the "Common  Stock"),  of Xybernaut  Corporation  (the "Company") by or for the
account of certain of the  Company's  stockholders  (collectively,  the "Selling
Stockholders"). See "Selling Stockholders."

           The Shares  offered  hereby may be sold by the  Selling  Stockholders
directly or through  agents,  underwriters or dealers as designated from time to
time or through a combination of such methods.  The Company will receive none of
the  proceeds  from any sale of  Shares  by or for the  account  of the  Selling
Stockholders.  The Selling  Stockholders and any broker-dealers that participate
with one or more of the Selling  Stockholders in the  distribution of the Shares
may be deemed to be underwriters and any commissions received or profit realized
by them in  connection  with the  resale  of the  Shares  might be  deemed to be
underwriting  discounts and  commissions  under the  Securities  Act of 1933, as
amended  (the  "Securities  Act").  See  "Selling  Stockholders"  and  "Plan  of
Distribution."  The  Company  has agreed to bear all  expenses  relating to this
registration,  other than underwriting  discounts and commissions.  In addition,
the Company has agreed to indemnify  the Selling  Stockholders  against  certain
liabilities,  including  liabilities  under the  Securities  Act.  See  "Selling
Stockholders" and "Plan of Distribution."

           The Common  Stock is quoted on the NASDAQ  SmallCap  Market under the
symbol "XYBR".  On September 17, 1997, the closing bid price of the Common Stock
as reported by NASDAQ was $2.75.

           *The shares of Common Stock offered hereby include the resale of such
presently  indeterminate  number of shares of Common Stock as shall be issued in
respect of all shares of Common Stock  issuable upon  conversion of 3,000 shares
of the  Company's  Series A  Preferred  Stock,  par value  $.01  (the  "Series A
Preferred  Stock"),  issued in a private  placement  in June 1997 (the  "Private
Placement").  The number of shares of Common  Stock  indicated to be issuable in
connection  with such  transaction  and offered for resale hereby is an estimate
and is,  based on  Registration  Rights  Agreements  (the  "Registration  Rights
Agreements") between the Company and each of the Selling  Stockholders,  150% of
the number of shares that would be issuable upon the  conversion of 3,000 shares
of the Series A Preferred Stock at a price of $3.50 per share, and 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.  If,  however,  all
3,000  shares  of the  Series  A  Preferred  Stock  currently  outstanding  were
converted  at the closing bid price of the Common Stock as reported by NASDAQ on
September 10, 1997, the Company would be obligated to issue a total of 1,285,713
shares of 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  into  which the  Series A  Preferred  Stock  will be
converted.  See "Risk Factors -- Series A Preferred  Stock" and  "Description of
Securities -- Preferred Stock -- Series A Preferred 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.

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  "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 Liquidation  Preference on all their shares of Series A Preferred
Stock plus accrued and unpaid dividends.  The Company has agreed to register the
shares  of  Common  Stock  underlying  the  Series  A  Preferred  Stock  in  the
Registration  Statement  filed with the  Commission.  If the Commission does not
declare the Registration  Statement effective by September 28, 1997, the Company
must pay each  holder  of the  Series A  Preferred  Stock 2% of the  outstanding
Liquidation  Preference of such holder's Series A Preferred Stock for each month
thereafter  that the  Registration  Statement  is not  declared  effective.  See
"Description of Securities -- Series A Preferred Stock."

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 nine months
ended December 31, 1995, the Company  incurred a net loss of $2,141,190.  In the
year ended December 31, 1996, the Company incurred a net loss of $5,238,536.  In
the six  months  ended  June  30,  1997,  the  Company  incurred  a net  loss of
$4,680,931.  At June  30,  1997,  the  Company  had an  accumulated  deficit  of
$13,453,806,   shareholders  equity  of  $5,122,020,   and  working  capital  of
$3,917,397.  The Company has a limited  operating history and 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.  The Company
is  currently  negotiating  with several  placement  agents the final terms of a
financing  of  approximately  $3,000,000  to  $5,000,000  of gross  proceeds and
expects to sign a commitment letter shortly,  and to close such financing within
30 days thereafter.  The Company's management believes that the proceeds of such
a financing,  in combination  with cash from  operations,  will be sufficient to
meet the Company's  operating and working  capital needs into the second quarter
at current levels of cash usage. There can be no assurance that the Company will
be capable of raising additional capital thereafter or that the terms upon which
such capital  would be available to the Company  would be  acceptable,  in which
case the  Company  could be  required  to curtail  materially,  suspend or cease
operations. 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.

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 June 30, 1997
had sold  and  delivered  approximately  $1.5  million  of  Mobile  Assistant(R)
systems.  The  Company  commenced  delivery  of  the  preproduction  586  Mobile
Assistant(R) in March 1997 and delivery of the  preproduction  Pentium(R) Mobile
Assistant  P-133(TM),  in August 1997. In September 1997, the Company  announced
linkAssist(TM),  a development toolkit, which provides speech linking of data in
almost any format,  without  altering the original  data. 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.

           The   commercial   success   of  the  Mobile   Assistant(R)   series,
linkAssist(TM),  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 any
of 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  InterVision,  Phoenix Group,  Computing
Devices  International,  a division of  Ceridian  Corporation,  ViA Inc.,  Texas
Microsystems,  Telxon,  Norand,  Interactive  Solutions,  Inc., a subsidiary  of
Teltronics, Inc. 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 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. The Company is aware of
at least three  competitors  that have introduced  hands-free  mobile  computing
systems  that compete  directly  with the Mobile  Assistant(R).  There can be no
assurance  that the  Company  will be able to compete  successfully  against its
competitors  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)  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


                                       -6-

<PAGE>



purchased from single suppliers. 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 two products:
one based on an AMD 5x86  processor  and the other based on an Intel  Pentium(R)
processor.  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) currently is priced
from  $4,995 to  $8,995,  depending  upon the model 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). 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  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.

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.  In September 1995, the Company received a notification from
the United  States Patent and Trademark  Office (the "Patent  Office")  entitled
"office action in reexamination" which indicated that the Company's claims under
its existing patent for the Mobile  Assistant(R)  were subject to  reexamination
and had been  preliminarily  rejected.  In May 1996, the Patent Officer 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 party that had initiated the prior
reexamination,  and in September 1996 the Company  received a notification  from
the


                                       -7-

<PAGE>



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  ultimate
validity  of the patent  will not be  resolved  until the  second  reexamination
request has been decided.  Most of the Company's  revenue for the 9 months ended
December  31, 1996 and for the six months  ended June 30, 1997 were derived from
products  included  within the scope of the  patent.  A final  rejection  of the
Company's patent could have a material adverse effect on the Company, including,
but not limited to, its  license  agreement  with  Rockwell  International  (the
Company has  granted to Rockwell  International  a  nonexclusive  license to the
patent and related technical  know-how),  although the Company believes that its
rights to  manufacture  and market its product are not dependent on this patent.
In October 1995,  the Company  filed a patent  application  covering  additional
embodiments and extensions of the technologies  used in the Mobile  Assistant(R)
series.  Notwithstanding  the  foregoing,  there  can be no  assurance  that the
Company's  pending patent  application  will issue as a patent,  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") and end users. The Company
is also developing a network of VARs and OEMs and to intends to enter into joint
ventures and licensing or other  collaborative  arrangements  to market and sell
its  mobile  computing  products.  The  Company  currently  is a  party  to  VAR
agreements with six entities.  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


                                       -8-

<PAGE>



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 six  month  period  ended  June  30,  1997,  three  customers
accounted  for  55% 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 size of its product
development  staff and to use outside  resources  in the near term to meet these
challenges.  There can be no assurance  that the Company will be  successful  in
hiring and training 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.

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


                                       -9-

<PAGE>



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 IPO price of $5.50 (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.
Management  expects that the stock and earnings targets for escrow release as of
September  30, 1997 will not be met and that  300,000  shares will be  cancelled
from the escrow pool,  which will result in a reduction of 2.1% of the Company's
currently outstanding shares of Common Stock.

CONTROL BY EXISTING STOCKHOLDERS

           Following this offering, the Company's executive officers,  directors
and  principal   stockholders   will,  in  the   aggregate,   beneficially   own
approximately  47.4% 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  15,544,825  shares of  Common  Stock to be
outstanding  upon the completion of this offering,  the 3,846,429 shares sold in
the IPO and the 1,285,713  additional  shares of Common Stock registered in this
offering will be freely tradeable. The remaining 10,412.683 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 10,205,437 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  5,641,819  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 250,000 shares  granted in September  1994, and $1.37 to
$3.00 for 912,530  shares  granted from April 1, 1995 to  September 1, 1997.  In
order to retain incentives for directors and current employees during this stage
of the Company's  development,  the strike price for certain options was reduced
to $3.00 per share by the  Company's  board of  directors  on August  28,  1997.
Current  control  persons and  board-elected  officers  are not affected by this
change.  The exercise price of the 212,860 warrants granted between July 1, 1996
and September 1, 1997 is between $2.38 and $18.00 per share.  In connection with
the  Company's  IPO,  warrants  to  purchase  3,846,429  shares were issued that
entitle the holder to purchase a share of common  stock for $9.00 until July 19,
1999. At the completion of the IPO, the  Representative  received an option (the
"Unit  Purchase  Option") to purchase  210,000  Units (the  "Units"),  each 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 is
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."

                                 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 June 1997  private  placement  (the  "Private
Placement")  and consist of the Common Stock  issuable  upon  conversion  of the
Series A Preferred Stock. In connection with the Private Placement,  the Company
granted the Selling  Stockholders  certain registration rights pursuant to which
the Company agreed to use its best efforts to keep the  Registration  Statement,
of which this Prospectus is a part,  effective until the earlier of (i) the date
that all the Shares have been sold pursuant to the Registration Statement,  (ii)
the date the Selling  Stockholders receive an opinion of counsel that the Shares
may be sold under the provisions of Rule 144 or (iii) the second  anniversary of

     the 1,285,713  shares of Common Stock  offered  hereby during the effective
     period of the Registration Statement. The actual number of shares of Common
     Stock offered hereby is subject to change and could be materially less than
     the estimated amount indicated,  depending upon (i) the average closing bid
     price of the Common  Stock for the five  trading  days prior to the date of
     conversion,  (ii)  whether  any of the  Series A  Preferred  Stock has been
     redeemed  and (iii)  whether the number of shares of the Series A Preferred
     Stock or the Common Stock outstanding have been adjusted to account for any
     stock dividend,  stock split,  recapitalization,  merger,  consolidation or

     the then issued and outstanding shares of Common Stock.

                            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,  14,259,112
shares of Common Stock are issued and  outstanding and 3,000 shares of Preferred
Stock is issued and outstanding.  The Company  currently has reserved  5,641,819
shares of Common Stock for issuance  pursuant to outstanding  options,  warrants
and the Unit Purchase Option.

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").  As of September 1, 1997,  three different
entities owned all 3,000 shares of the Series A Preferred Stock.

           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 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.


                                      -15-

<PAGE>



           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.


                                      -16-

<PAGE>



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 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


                                      -17-

<PAGE>



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)  shall  rank on a pari passu
basis with 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 agreed to register the shares of
Common  Stock  underlying  the  Series A  Preferred  Stock  in the  Registration
Statement  filed with the  Commission.  If the  Commission  does not declare the
Registration  Statement  effective by September  28, 1997,  the Company must pay
each holder of the Series A Preferred  Stock 2% of the  outstanding  Liquidation
Preference of such holder's Series A Preferred  Stock for each month  thereafter
that the Registration Statement is not declared effective.

           Other Designations of Preferred Stock

           As of the date of this Prospectus, the Company has not designated any
shares of  Preferred  Stock other than the Series A Preferred  Stock  designated
pursuant to the Private Placement.  There are no other shares of Preferred Stock
outstanding, and the Company currently has no plans to issue any other shares of
Preferred Stock.

                    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


                                      -18-

<PAGE>



(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
Common  Stock,  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  one  or  more  of  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 any of 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.

           The  Selling  Stockholders  may from time to time  pledge  the Shares
owned by them to secure margin or other loans made to one or more of the Selling
Stockholders.  Thus,  the  person or entity  receiving  the pledge of any of the
Shares may sell them, in a foreclosure sale or otherwise,  in the same manner as
described above for a 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  use  its  best  efforts  to  keep  the
Registration  Statement of which this  Prospectus is a part effective  until the
earlier  of (i) the date that all the  Shares  have been  sold  pursuant  to the
registration  statement of which this  Prospectus  is a part,  (ii) the date the
Selling  Stockholders  receive an opinion of counsel that the Shares may be sold
under  the  provisions  of Rule  144 or  (iii)  the  second  anniversary  of the
effective date of the  Registration  Statement of which this Prospectus  forms a
part.

                 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   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 Agreements,  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 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


                                      -21-

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.

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


                                     II - 1

<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.

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

ITEM 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;

           (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.


                                     II - 2

<PAGE>



           (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.

           Section 3. General Representations and Warranties of the Company. The
Company  hereby  represents  and warrants to, and covenants  with, the Purchaser
that the  following  are true and  correct  as of the date  hereof and as of the
Closing Date.

           3.1  Organization;  Qualification.  The Company is a corporation duly
organized and validly existing under the laws of the State of Delaware and is in
good standing under such laws. The Company has all requisite corporate power and
authority to own, lease and operate its  properties and assets,  and to carry on
its business as presently conducted.  The Company is qualified to do business as
a  foreign  corporation  in each  jurisdiction  in which  the  ownership  of its
property or the nature of its business requires such qualification, except where
failure to so qualify would not have a material adverse effect on the Company.

           3.2  Capitalization.  The  authorized  capital  stock of the  Company
consists of 30,000,000  shares of Common Stock,  $0.01 par value per share,  and
5,000,000 shares of nonvoting  Preferred Stock, $0.01 par value, which have been
designated  Series A Convertible  Preferred  Stock, no par value. All issued and
outstanding  shares of Common Stock have been duly authorized and validly issued
and are  fully  paid  and  nonassessable.  The  Company  will  reserve  from its
authorized but unissued shares of Common Stock a sufficient  number of shares of
Common Stock to permit the conversion in full of the outstanding  Shares.  As of
the Closing Date, the Company had reserved sufficient shares of Common Stock for
issuance  upon  exercise of the Shares  which are  convertible,  at  Purchaser's
option, at the Conversion Price, as per Section 9 of this Agreement.

           3.3  Authorization.  The Company has all requisite  corporate  right,
power and authority to execute and deliver this  Agreement and to consummate the
transactions  contemplated  hereby.  All  corporate  action  on the  part of the
Company, its directors and stockholders necessary for the

                                        3

authorization,  execution,  delivery and  performance  of this  Agreement by the
Company,  the authorization,  sale,  issuance and delivery of the Shares and the
performance  of  the  Company's  obligations  hereunder  has  been  taken.  This
Agreement has been duly executed and delivered by the Company and  constitutes a
legal,  valid and binding  obligation of the Company  enforceable  in accordance
with its terms,  subject to laws of general application  relating to bankruptcy,
insolvency  and the  relief  of  debtors  and  rules of law  governing  specific
performance,  injunctive relief or other equitable remedies,  and to limitations
of public policy as they may apply to the  indemnification  provisions set forth
in Section 7.3 of this Agreement.  Upon their issuance and delivery  pursuant to
this Agreement,  the Shares will be validly issued, fully paid and nonassessable
and  will be free of any  liens or  encumbrances;  provided,  however,  that the
Shares are subject to  restrictions  on  transfer  under  state  and/or  federal
securities  laws.  The issuance and sale of the Shares will not give rise to any
preemptive  right or right of first refusal or right of  participation on behalf
of any person.

           3.4 No Conflict. The execution and delivery of this Agreement do not,
and the consummation of the transactions  contemplated hereby will not, conflict
with,  or result in any  violation  of, or  default,  or give rise to a right of
termination,  cancellation or  acceleration  of any material  obligation or to a
loss  of  a  material   benefit,   under,  any  provision  of  the  Articles  of
Incorporation,  and any amendments thereto, Bylaws,  Stockholders Agreements and
any amendments thereto of the Company or any material mortgage, indenture, lease
or other  agreement  or  instrument,  permit,  concession,  franchise,  license,
judgment,  order, decree statute, law, ordinance,  rule or regulation applicable
to the Company, its properties or assets and which would have a material adverse
effect on the Company's business and financial condition.

           3.5  Accuracy  of Reports  and  Information.  The  Company is in full
compliance,  to the extent  applicable,  with all  reporting  obligations  under
either Section 12(b), 12 (g) or 15(d) of the Securities Exchange Act of 1934, as
amended  (the  "Exchange  Act").  The Company has  registered  its Common  Stock
pursuant to Section 12 of the  Exchange  Act and the Common  Stock is listed and
trades on the Nasdaq National Small Cap Market.

all reporting  obligations,  under either Section 13(a) or 15(d) of the Exchange
Act for a period of at least twelve (12) months immediately  preceding the offer
to sale of the Shares (or for such  shorter  period  that the  Company  has been
required to file such material).

           3.6 SEC  Filings/Full  Disclosure.  Since completion of the Company's
initial  public  offering in July 1996,  none of the Company's  filings with the
Securities and Exchange  Commission  contain any untrue  statement of a material
fact or omit to state  any  material  fact  required  to be  stated  therein  or
necessary to make the  statements  therein in light of the  circumstances  under
which they were made, not misleading. The Company has timely filed all requisite
forms, reports and exhibits thereto with the Securities and Exchange Commission.

the Company to perform its obligations pursuant to this Agreement.

           3.7 Absence of Undisclosed  Liabilities.  The Company has no material

aggregate),  except as set forth in the  financial  statements or as incurred in
the ordinary course of business after the date of the financial statements.

           3.8 Governmental Consent, etc. No consent,  approval or authorization
of or designation,  declaration or filing with any governmental authority on the
part of the Company is  required  in  connection  with the valid  execution  and
delivery of this Agreement, or the offer, sale or issuance of the Shares, or the
consummation of any other  transaction  contemplated  hereby,  except the filing

conditions,  affairs or operations of the Company. The Company is not a party to
or subject to the provisions of any order, writ, injunction,  judgment or decree
of any court or government agency or instrumentality.

           3.12 Title to Assets. Except as set forth in Reports, the Company has

           3.16 Other Outstanding Securities/Financing  Restrictions. Other than
warrants  and  options to acquire  shares of Common  Stock as  disclosed  in the
Reports,  there are no other  outstanding  securities  debt or equity  presently
convertible into Common Stock. The Company has no outstanding  restricted share,

unrestricted ("free trading") stock.

           3.17 Legal  Opinion.  Purchaser  shall,  upon purchase of the Shares,
receive  an  opinion  letter  from  counsel  to the  Company,  and  the  Company
represents that it will  immediately  obtain such an opinion from counsel to the

                      (vii) The  issuance  of the Shares  will not  violate  the

Purchaser.  The Purchaser  represents  and warrants to, and covenants  with, the

the transactions  contemplated hereby. This Agreement has been duly executed and
delivered by the  Purchaser  and will  constitute  the legal,  valid and binding
obligations of the Purchaser,  enforceable in accordance with its terms, subject
to laws of general application relating to bankruptcy, insolvency and the relief
of debtors and rules of law governing specific performance, injunctive relief or
other equitable remedies,  and to limitations of public policy as they may apply
to the indemnification provisions set forth in Section 7.3 of this Agreement.

           4.2 Investment  Experience.  Purchaser is an "accredited investor" as
defined in Rule  501(a)  under the  Securities  Act.  Purchaser  is aware of the
Company's  business  and  financial  condition  and  has had  access  to and has
acquired  sufficient  information about the Company,  including the Reports,  to
reach an informed and  knowledgeable  decision to acquire the Shares.  Purchaser
has  such  business  and  financial  experience  as is  required  to give it the
capacity to protect its own  interests  in  connection  with the purchase of the
Shares.  Purchaser  has the  ability to bear the  economic  risk of  Purchaser's
investment pursuant to this Purchase Agreement. Purchaser has not been organized
for the purpose of investing in securities of the Company,

                                        7

although such investment is consistent with Purchaser's purpose.

           4.3  Investment  Intent.  Without  limiting its ability to resell the
Shares  and  underlying  Common  Stock  pursuant  to an  effective  registration
statement,  Purchaser  represents  that it is purchasing  the Shares for its own
account as principal for investment  purposes.  Purchaser  understands  that its
acquisition  of the Shares has not been  registered  under the Securities Act or
registered or qualified  under any state  securities law in reliance on specific
exemptions therefrom,  which exemptions may depend upon, among other things, the
bona fide nature of Purchaser's investment intent as expressed herein. Purchaser
will not, directly or indirectly,  offer,  sell,  pledge,  transfer or otherwise
dispose of (or solicit any offers to buy, purchaser or otherwise acquire or take
a pledge of) any of the Shares except in compliance  with the Securities Act and
any applicable state securities laws, and the rules and regulations  promulgated
thereunder.

           4.4  Registration  or  Exemption   Requirements.   Purchaser  further
acknowledges and understands  that the Shares may not be transferred,  resold or
otherwise  disposed of except in a transaction  registered  under the Securities
Act and any applicable  state  securities  laws or unless an exemption from such
registration  is  available.   Purchaser  understands  that  the  certificate(s)
evidencing  the  Shares  will be  imprinted  with a legend  that  prohibits  the
transfer of the Shares unless (i) they are  registered or such  registration  is
not  required,  and  (ii) if the  transfer  is  pursuant  to an  exemption  from
registration  other than Rule 144 under the  Securities  Act and, if the Company
shall so request in writing,  an opinion of counsel  reasonably  satisfactory to
the Company is obtained to the effect that the transaction is so exempt.

           4.5 No Legal, Tax or Investment  Advice.  Purchaser  understands that
nothing in this  Agreement  or any other  materials  presented  to  Purchaser in
connection with the purchase and sale of the Shares  constitutes  legal,  tax or
investment advice.  Purchaser has relied on, and has consulted with, such legal,
tax and investment advisors as it, in its sole discretion,  has deemed necessary
or appropriate in connection with its purchaser of the Shares.

           4.6 Purchaser  Review.  Purchaser hereby represents and warrants that
the Purchaser has  carefully  examined the Reports and the financial  statements
contained  therein.  The  Purchaser  acknowledges  that  the  Company  has  made
available to the Purchaser all documents and  information  that it has requested
relating  to the  Company  and  has  provided  answers  to all of its  questions
concerning  the Company  and the  Shares.  Nothing  stated in the  previous  two
sentences, however, shall be deemed to affect the representations and warranties
of the Company contained in this Agreement.

           4.7  Restrictions  on  Conversion  of Shares.  The  Purchaser  or any
subsequent  holder  of the  shares  (the  "Holder")  shall  be  prohibited  from
converting  any portion of the Shares which would result in the Purchaser or the
Holder being deemed the beneficial  owner,  in accordance with the provisions of
Rule 13d-3 of the  Securities  Exchange Act of 1934,  as amended (the  "Exchange
Act"), of 4.99% or more of the then issued and  outstanding  Common Stock of the
Company.

           Section 5. Conditions to the Purchaser's  Obligation to Purchase. The
Company  understands that the Subscriber's  obligation to purchase the Shares is

           7.1  Registration  Rights  Agreement.  The parties  will enter into a
Registration Rights Agreement, annexed hereto as Attachment II.

           7.2 Underwriter. The Company understands that the Purchaser disclaims
being an "underwriter" (as such term is defined under the Securities Act and the
rules and regulations promulgated thereunder (an "Underwriter")),  but Purchaser
being deemed an  Underwriter  shall not relieve the Company of any obligation it
has hereunder, except as may be required by law.

           7.3 Indemnification.  Each of the Company and the Purchaser agrees to
indemnify the other and to hold the other  harmless from and against any and all
losses,   damages,   liabilities,   costs  and  expenses  (including  reasonable
attorneys'  fees)  which the other may sustain or incur in  connection  with the
breach by the  indemnifying  party of any  representation,  warranty or covenant
made by it in this Agreement.

           7.4 Information  Available.  So long as any registration statement is
effective covering the resale of the Conversion Shares, the Company will furnish
to Purchaser:

Company's Annual Report to  Stockholders,  within 150 days after the end of each

that is generally available to the public.

           7.5  Temporary  Cessation  of  Offers  and  Sales by  Purchaser.  The
Purchaser acknowledges that there may occasionally be times when the Company may
be  required  to  suspend  the  use  of  the  prospectus  forming  part  of  the
Registration  Statement  until  such time as an  amendment  to the  Registration
Statement  has  been  filed  by  the  Company  and  declared  effective  by  the
Commission,  until the prospectus is  supplemented or amended to comply with the
Securities  Act,  or until  such time as the  Company  has files an  appropriate
report with the  Commission  pursuant to the Exchange Act. The Company agrees to
file any necessary  amendments,  supplements  and reports as soon as practicable
under the  circumstances.  Purchaser  hereby covenants that it will not sell any
Common  Stock  pursuant to said  prospectus  during a period of not more than 45
days  commencing at the time at which the Company gives the Purchaser  notice of
the suspension of the use of said  prospectus and ending at the time the Company
gives the  Purchaser  notice that the  Purchaser  may  thereafter  effect  sales
pursuant to said prospectus, as the same may have been supplemented or amended.

           7.6 Transfer of Common  Stock After  Registration.  Purchaser  hereby
covenants  with the  Company  not to make any sale of the  Common  Stock  except
either  (i) in  accordance  with  the  Registration  Statement,  in  which  case
Purchaser  covenants  to comply with the  requirement  of  delivering  a current
prospectus,  or (ii)  such  time as all of the  Common  Stock may be sold in any
three-month period pursuant to Rule 144 under the Securities Act.

           7.7  Termination  of  Obligations.  The  obligations  of the  Company
pursuant to the Registration Rights Agreement shall cease and terminate upon the

month period pursuant to Rule 144 under the Securities Act.

           7.8 Legend.  The certificate or certificates  representing the Shares
and,  upon  conversion,  the  Conversion  Shares  shall be  subject  to a legend

substantially as follows:


                                       10

<PAGE>



           "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES  ACT OF 1933,  AS AMENDED (THE  "ACT").  THESE  SECURITIES  HAVE BEEN
ACQUIRED FOR INVESTMENT,  AND MAY NOT BE TRANSFERRED OR DISPOSED OF UNLESS (1) A
REGISTRATION  STATEMENT UNDER THE ACT IS THEN IN EFFECT WITH RESPECT THERETO AND
SUCH  SALE IS MADE  PURSUANT  TO SUCH  REGISTRATION  STATEMENT  OR (2) A WRITTEN
OPINION FROM COUNSEL  REASONABLY  SATISFACTORY TO THE COMPANY IS OBTAINED TO THE
EFFECT THAT SUCH TRANSFER OR DISPOSITION  WILL NOT VIOLATE THE ACT AND THE RULES
AND REGULATIONS PROMULGATED THEREUNDER."

Such securities  shall also include any legends required by any applicable state
securities laws.

           With respect to the Shares and the Conversion  Shares,  the legend(s)
shall be removed and the Company shall issue a replacement  certificate  without
such legend to the holder of such  certificate  if such  holder  provides to the
Company an  opinion of counsel  reasonably  acceptable  to the  Company,  to the
effect  that a sale,  transfer  or  assignment  of such  securities  may be made
without registration.

           7.10 Permissive  Redemption.  The Company has the right to redeem the
Shares, in whole or in part, in cash or in Common Stock, as follows:

           When a conversion  request is submitted and when the Conversion Price
is at or below $2.625,  the Company has the option to redeem all or a portion of
the first twenty-five  (25%) percent of the outstanding  Shares for a redemption
price  equal to one  hundred  ten (110%)  percent of the  Liquidation  Value (as
defined in the Certificate of  Designation) of the Shares,  or issue shares at a
redemption  price equal to eighty-two  (82%) percent of the average  closing bid
price of the Common  Stock as  reported by NASDAQ or any  successor  exchange in
which the Common  Stock is listed for the five (5) trading  days  preceding  the
Conversion Date. For all or a portion of the second twenty-five (25%) percent of
outstanding Shares for which conversions are submitted,  if the Conversion Price
is at or below  $2.625,  the  Company  has the option to redeem for one  hundred
twenty (120%) percent of the Liquidation Value of the Shares, or issue shares at
a redemption  price equal to eighty-two (82%) percent of the average closing bid
price of the Common Stock as reported by NASDAQ or on other securities exchanges
or  markets in which the Common  Stock is listed  for the five  (5)trading  days
ending on the day before the Closing Date.

           For any  conversions of the remaining  outstanding  principal  amount
submitted at or below a floor price of One ($1.00) Dollar per Conversion  Share,
Shares may be  redeemed  by the  Company at the  time(s)  of  conversion  at one
hundred ten (110%) percent of the Liquidation Value of the Shares.

           The Company shall give written notice by telecopy to the Purchaser of
its  election  to redeem the Shares one (1)  business  day after  receipt of the
Notice of Conversion.  Upon notice of its right to redeem the Shares the Company
shall wire transfer the appropriate amount of funds

                                       11

which shall include  Redemption  Price, as defined in Certificate of Designation
filed June 30, 1997, and any and all penalties and liquidated  damages,  if any,
to Purchaser  within ten (10) days of such notice.  If the Company does not wire
the  appropriate  amounts of funds to  Purchaser,  the Company  shall pay to the
Purchaser  a  penalty  in an  amount in cash  equal to two (2%)  percent  of the
redemption price to be paid for such redemption. If the Company fails to pay the
Redemption  Price on the  Redemption  Date,  as  defined in the  Certificate  of
Designation  filed June 30, 1997, the Purchaser  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  accordance  with  the  terms  of  this  paragraph  in any  subsequent
redemption;  provided,  however, that if the Company fails to pay the Redemption
Price in a subsequent  redemption  within ten (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.

                          REGISTRATION RIGHTS AGREEMENT


           THIS REGISTRATION RIGHTS AGREEMENT,  dated June 30, 1997, between the
person  and/or  entity  whose name and  address  appears on the  signature  page
attached hereto (individually a "Holder" or collectively with the holders of the
other  Securities  issued pursuant to a 5% Convertible  Preferred Stock Purchase
Agreement of even date herewith,  as defined below, the "Holders") and XYBERNAUT
CORPORATION,  a corporation having its principle place of business at 12701 Four
Lakes Circle, Fairfax, VA 22033.

           WHEREAS,  simultaneously  with the  execution  and  delivery  of this
Agreement,  the  Holders  are  purchasing  from the  Company,  pursuant  to a 5%
Convertible  Preferred Stock Securities Purchase Agreement dated the date hereof
(the  "Agreement"),  an aggregate of up to Three  Million  ($3,000,000)  Dollars
principal amount of Convertible Preferred Shares (the "Preferred Shares"); and

           WHEREAS,  the  Preferred  Shares are  convertible  into  shares  (the
"Conversion  Shares") of the Company's  Common Stock,  par value $0.01 per share
(the "Common Stock"); and

           WHEREAS, the Company desires to grant to the Holders the registration
rights set forth herein with respect to the Conversion Shares.

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

           Section  1.   Registrable   Securities.   As  used  herein  the  term
"Registrable Security" means each of the Conversion Shares;  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 "Securities Act") and disposed of pursuant thereto, (ii) registration under
the Securities Act is no longer required for the immediate  public  distribution
of such  security  as a result of the  provisions  of Rule 144,  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  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 Holder  acknowledges  and
understands that prior to the registration of the Conversion  Shares as provided
herein,   the  Preferred  Shares  and  the  Conversion  Shares  are  "restricted
securities"  as  defined  in Rule 144  promulgated  under  the Act.  The  Holder
understands  that  no  disposition  or  transfer  of  the  Preferred  Shares  or
Conversion  Shares  may be made by Holder in the  absence  of (i) an  opinion of
counsel reasonably satisfactory to the Company that such transfer may be made or
(ii) a  registration  statement  under the Securities Act is then in effect with
respect thereto.

           Section 3. Registration Rights.

           (a) The Company shall prepare and file a registration  statement (the
"Registration  Statement") with the Securities and Exchange  Commission ("SEC"),
on one  occasion,  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  non-underwritten  public  offering  and  sale of the  Registrable
Securities under the Act. The number of Registrable  Securities to be registered
shall be one hundred fifty (I 50%) percent of the number of shares that would be
required if all the  Registrable  Securities  were converted at a price of $3.50
per share on the effective date of the Registration Statement.

           (b)  The  Company  will  maintain  any   Registration   Statement  or
post-effective  amendment  filed under this Section 3 hereof  current  under the
Securities  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  the  Registrable
Securities  may be sold  under the  provisions  of Rule 144 or (iii) the  second
anniversary of the effective date of the Registration Statement.

           (c) All fees,  disbursements  and  out-of-pocket  expenses  and costs
incurred by the Company in  connection  with the  preparation  and filing of any
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 use its best efforts to 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 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 such  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 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 purchasers
or transferees  obtaining securities which are not "restricted  securities",  as
defined in Rule 144 under the Securities Act.

           (e) In the  event  the  Registration  Statement  to be  filed  by the
Company  pursuant to Section 3 (a) above is not  declared  effective  by the SEC
within ninety (90) days of the Closing Date, as defined in the Agreement,  then,
unless waived by Holder,  the Company will pay Holder, as liquidated damages for
such failure and not as a penalty, two (2%) percent of the outstanding principal
amount of the  Preferred  Shares for each  month  thereafter  until the  Company
procures  registration of the Common Stock  underlying the Preferred Shares (the
"Conversion Shares").

           If the Company  does not remit the damages to the Holder as set forth
above,  the  Company  will pay the  Holder's  reasonable  costs  of  collection,
including  attorneys fees, in addition to the liquidated  damages.  Such payment
shall be made to the Holder  immediately if the  registration  of the Conversion
Shares are not effected;  provided, however, that the payment of such liquidated
damages  shall not relieve  the Company  from its  obligations  to register  the
Conversion  Shares pursuant to this Section.  The registration of the Conversion
Shares  pursuant  to this  provision  shall not affect or limit  Holder's  other
rights or remedies as set forth in this

                                        2

<PAGE>



Agreement.  Any payment  pursuant to this  Section  3(e) shall be made either in
cash or paid in  additional  shares of  Common  Stock at the  discretion  of the
Company.

           (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.

           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:

           (a) prepare and file with the SEC such  amendments and supplements to
such 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 or
Holders 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 of
the SEC);

           (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) use its best  efforts to  register  and  qualify  the  securities
covered by such  registration  statement under such other securities or blue sky
laws of such jurisdictions as the Holder,  shall reasonably request,  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) use its best  efforts  to list such  securities  on NASDAQ or any
securities  exchange on which any  securities of the Company is then listed,  if
the  listing  of such  securities  is then  permitted  under  the  rules of such
exchange or NASDAQ;

           (e) enter into and  perform  its  obligations  under an  underwriting
agreement,  if the offering is an underwritten  offering, in usual and customary
form,  with  the  managing  underwriter  or  underwriters  of such  underwritten
offering;

           (f) notify  each  Holder of  Registrable  Securities  covered by such
registration  statement,  at any time when a prospectus relating thereto covered
by such 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 such registration  statement, as then in effect, includes
an untrue statement of a material fact or omits to state

                                        3

<PAGE>



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) In the event of the  filing of any  Registration  Statement  with
respect to  Registrable  Securities  pursuant  to Section 3 hereof,  the Company
agrees to  indemnify  and hold  harmless  the  Holder  ("Distributing  Holders")
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
reasonable costs of defense and investigation and all attorneys' fees), to which
the  Distributing  Holders  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 any untrue statement or alleged
untrue  statement  of any  material  fact  contained  in any  such  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 will not be liable (i) 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 such  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 the  Distributing  Holders,  specifically for use in
the  preparation  thereof,  or (ii) to pay any amounts paid in settlement of any
loss,  claim,  damage or liability if such  settlement  is effected  without the
consent of the  Company.  This  indemnity  agreement  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  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,
or director 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 any untrue  statement or alleged untrue statement
of any material fact  contained in a  Registration  Statement  requested by such
Distributing  Holder, 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  such  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 and,
provided further,  that the indemnity  agreement  contained in this Section 6(b)
shall not  inure to the  benefit  of the  Company  with  respect  to any  person
asserting such loss,  claim,  damage or liability who purchased the  Registrable
Securities  which are the subject  thereof if the Company failed to send or give
(in violation of the  Securities  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  to such person of the sale
of such Registrable  Securities,  where the Company was obligated to do so under
the Securities Act or the rules and  regulations  promulgated  thereunder.  This
indemnity  agreement will be in addition to any liability which the Distributing
Holders may otherwise have.


                                        4

           (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
reasonable  out-of-pocket  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  reasonable  out-ofpocket  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
reasonable  fees and  out-of-pocket  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
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 understood,  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  outof-pocket  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.  Notices.  Any notice  pursuant to this  Agreement  by the

                                                              September 22, 1997

Xybernaut Corporation

Fairfax, Virginia  22033

Gentlemen:

           We have  acted  as  counsel  to  Xybernaut  Corporation,  a  Delaware
corporation (the "Company"), in connection with a 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 1,285,713  shares (the "Shares") of Common Stock, par value $.01 per
share (the "Common  Stock"),  issuable upon conversion of the Company's Series A
Preferred Stock (the "Series A Preferred Stock"), par value $.01 per share.

           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 upon conversion of the Series A Preferred Stock, will be
validly issued, fully paid and non-assessable.

           We hereby  consent to the filing of this opinion as an exhibit to the
Registration Statement.


                                         Very truly yours,

                                         /s/ Parker Chapin Flattau & Klimpl, LLP

                                         PARKER CHAPIN FLATTAU & KLIMPL, LLP






                                                                    EXHIBIT 23.1
                                                                    ------------


                       CONSENT OF INDEPENDENT ACCOUNTANTS
                       ----------------------------------


We consent to the  inclusion in this  registration  statement on Form S-3 of our
report  dated  March 31,  1997,  on our audits of the  financial  statements  of

caption "Experts."
