==========================================================================================


(1)   Represents the  registration for resale of 150% of the number of shares of
      the Company's common stock that would be issuable upon conversion by three
      holders of 375 shares of the Company's Series C Preferred Stock at a price
      of $3.40 per share of common stock.

(2)   Estimated  solely for the  purpose of  calculating  the  registration  fee
      pursuant to Rule 457(c) and (g);  based on the average  ($4.734375) of the
      bid ($4.718750) and asked  ($4.750000) price on the Nasdaq SmallCap Market
      on July 9, 1998.

(3)   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 375 shares of the Company's  Series C Preferred  Stock,  par value $.01
      (the  "Series C Preferred  Stock"),  issued in a private  placement in May
      1998 (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 a  Registration  Rights
      Agreement (the "Registration  Rights Agreement") among the Company and the
      Selling Stockholders,  150% of the number of shares that would be issuable
      upon  conversion of 375 shares of the Series C Preferred  Stock at a price
      of $3.40 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 375 shares of the Series
      C Preferred Stock currently  outstanding were converted at the closing bid
      price of the  Common  Stock as  reported  by NASDAQ on July 9,  1998,  the
      Company  would be  obligated  to issue a total of 79,470  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 C Preferred Stock will be converted.

      Securities -- Preferred Stock -- Series C Preferred Stock."

            This  Prospectus  pertains to the offer and sale, from time to time,
by or for the account of certain  stockholders  (the "Selling  Stockholders") of
Xybernaut Corporation (the "Company"), of up to 165,441 shares (the "Shares") of
common stock, par value $.01 per share (the "Common Stock"), of the Company. See
"Description of Securities."

            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 not receive any
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 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

            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 375 shares of
the Company's  Series C Preferred Stock, par value $.01 (the "Series C Preferred
Stock"),  issued in a private  placement in May 1998 (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 a
Registration  Rights Agreement (the  "Registration  Rights Agreement") among the
Company and the Selling Stockholders, 150% of the number of shares that would be
issuable  upon  conversion  of 375 shares of the Series C  Preferred  Stock at a
price of $3.40 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 375 shares of the Series C Preferred  Stock
currently  outstanding  were  converted  at the  closing bid price of the Common
Stock as reported by NASDAQ on July 9, 1998,  the Company  would be obligated to
issue a total of  79,470  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 C
Preferred  Stock will be  converted.  See "Risk  Factors  -- Series C  Preferred
Stock" and  "Description  of Securities -- Preferred Stock -- Series C Preferred

                               PROSPECTUS SUMMARY

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

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

                                  RISK FACTORS

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

HISTORY AND EXPECTATION OF FUTURE LOSSES; NEED FOR ADDITIONAL FINANCING

           The Company was incorporated in October 1990 and commenced operations
in November 1992. In the fiscal years ended March 31, 1994 and 1995, the Company
incurred a net loss of $47,352 and $1,303,892,  respectively. In the years ended
December 31, 1996 and 1997,  the Company  incurred a net loss of $5,238,536  and
$9,479,966,  respectively. The Company incurred a net loss of $1,489,321 for the
quarter  ended March 31, 1998 and  expects to incur a  substantial  loss for the
quarter ended June 20, 1998. The consolidated  balance sheets as of December 31,
1997  and  1996  and  the  related   consolidated   statements  of   operations,
stockholders'  equity, and cash flows for the years then ended,  incorporated by
reference in this Prospectus,  have been incorporated  herein in reliance on the
report dated March 31, 1998, which includes an explanatory paragraph, concerning
the Company's ability to continue as a going concern, of  PricewaterhouseCoopers
LLP, independent accountants,  given on their authority as experts in accounting
and auditing.  The Company intends to conduct significant  additional  research,
development  and testing  that,  together  with  establishment  of marketing and
distribution  capabilities,  are expected to require  substantial funding and to
result in  continuing  operating  losses  until  such time as  sufficient  gross
margins from revenues are generated to cover  operating  costs.  There can be no
assurance that, notwithstanding these efforts and the expenditure of substantial
funds, the Company ever will achieve substantial sales of any of its products or
profitable operations or that it will be able to meet the competitive demands of
the industry in which it  operates.  The success of the Company will be affected
by expenses,  operational  difficulties and other factors frequently encountered
in the development of a business enterprise in a competitive  environment,  many
of which may be beyond the Company's control. See "Risk Factors - Competition."

LIQUIDITY; WORKING CAPITAL NEEDS

           To meet working  capital cash  requirements,  the Company  intends to
obtain a working  capital line of credit and/or complete  additional  financings
including  the exercise of its put option  under the April 1998  Private  Equity
Line of Credit Private Placement (the "Put Option") which  contemplates the sale
of up to  $11,000,000  of the Company's  Common Stock over a period of up to two
years. To date, the Company has sold $1,000,000  worth of shares of Common Stock
and exercised a put option in the aggregate  principal amount of $3,000,000 (the
"Initial Put Option"),  each under the April 1998 Private  Equity Line of Credit
Private  Placement.  However,  there can be no assurance that the Company can or
will obtain  sufficient  funds to meet, in whole or in part, its working capital
needs from  collections  of product  sales.  There can be no assurance  that the
Company  will  be  capable  of  raising  additional  capital  thereafter  or  of
establishing and obtaining funds from a working capital line of credit, that the
exercise of a put option will be  accepted  by the  particular  investor or that
such exercise  will be deemed  advisable at such times as funds may be required,
or that the terms upon which such  capital or line of credit  would be available
to the Company would be acceptable,  in which case the Company could be required
to curtail materially, suspend or cease operations.

DILUTION; IMPACT OF SALE OF COMMON STOCK UPON CONVERSION OF OUTSTANDING
OPTIONS, WARRANTS, THE UNIT PURCHASE OPTION AND CERTAIN REPRICING OPTIONS



                                       -4-





           The purchasers of the Shares offered hereby will experience immediate
and substantial  dilution in the net tangible value of their Shares in the event
of conversion  of  outstanding  options,  warrants and the issuance of shares of
Common  Stock  pursuant to certain  repricing  arrangements  entered into by the
Company in connection with its exercise of the Initial Put Option. Specifically,
certain options and warrants are 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 sale of such Common  Stock
acquired at a discount could have a negative  impact on the trading price of the
Common  Stock and could  increase  the  volatility  in the trading  price of the
Common Stock.

           At the date of this Prospectus, the Company has reserved an aggregate
of  6,983,832  shares of Common  Stock for  issuance on exercise of  outstanding
options and warrants. The exercise price of the options presently outstanding is
between $1.37 and $6.00 for 1,290,430  shares granted from April 1, 1995 to July
9, 1998.  The exercise price of the 287,860  warrants  outstanding as of July 9,
1998 is between  $1.76 and $18.00 per share.  In  connection  with the Company's
IPO,  warrants to purchase  3,846,429 shares were originally issued that entitle
the holder to purchase a share of common  stock for $9.00  until July 19,  1999.
These warrants contain anti-dilution provisions that have resulted in the number
of shares to be issued upon a complete warrant exercise increasing to 4,583,402.
At the completion of the IPO, the  Representative  received an option (the "Unit
Purchase Option") to purchase 210,000 Units (the "Units"),  each 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.

           In addition,  the Company agreed to certain repricing arrangements in
connection  with its  exercise  of the  Initial  Put  Option.  Pursuant  to such
arrangement,  one-sixth of the 545,454  shares of Common Stock (the "Initial Put
Shares") issued upon exercise of the Initial Put Option,  are subject to monthly
repricing commencing on September 30, 1998. Under the repricing calculation,  if
the closing price of the Common Stock on the trading date immediately  preceding
the  repricing  date is less than  $7.20 per share,  the shares of Common  Stock
subject to  repricing  shall be repriced at the lowest  closing bid price of the
Common Stock for the 30 days  preceding  such  repricing  date (the "Initial Put
Reset  Price").  The Company shall issue to the investors  such number of shares
(the "Initial Put Repricing  Shares")  equal to the  difference  between (a) the
quotient of 500,000 and the Initial Put Reset Price and (b) the number of shares
subject to repricing.  No  additional  shares of Common Stock shall be issued if
the Initial Put Reset Price is equal to or greater than $5.50.

UNCERTAINTY OF MARKET DEVELOPMENT AND PRODUCT ACCEPTANCE

           The mobile computing  market is emerging and relatively  undeveloped.
The Company  sold its first Mobile  Assistant(R)  in 1993 and as of December 31,
1997 had sold and delivered  approximately  $1.8 million of Mobile  Assistant(R)
systems.  The Company  commenced  delivery of the  Pentium(R)  Mobile  Assistant
P-133(TM) in August 1997 and has announced that it expects to commence  delivery
of Mobile  Assistant(R)  IV, a Pentium 266 MHZ based  system  ("MA IV"),  in the
quarter  ending  December 31, 1998.  In September  1997,  the Company  announced
linkAssist(TM), a software development toolkit, which provides speech linking of
data in almost any format, without


                                       -5-





altering  the  original  data  and  webAssist(TM)  software  that  allows  voice
navigation  of HTML links found on the  Internet and  intranet.  The size of the
mobile computing  market is currently  limited by the high unit prices of mobile
computers as compared to laptops and other portable  computers,  the specialized
nature of each  application  and the need for  custom  applications  and  system
integration and the limited supply to date of components for completed  systems.
The  potential  size  of the  market  will  be  limited  by the  rate  at  which
prospective  customers  recognize and accept the functions and  capabilities  of
integrated  mobile  computing  systems.   There  can  be  no  assurance  that  a
significant  market will  develop for mobile  computing  systems or, if a market
develops,  that the Mobile  Assistant(R)  series and any of the Company's  other
products  will  become a  significant  factor in any market  that  develops.  In
addition, there is no assurance that the Company will obtain the working capital
needed to meet the competitive demands of the industry in which it operates. See
"Risk Factors - Liquidity; Working Capital Needs; -- Competition."

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

           The   Company   believes   that  any  product   acceptance   will  be
substantially dependent upon educating the commercial, healthcare, education and
military markets as to the capabilities,  characteristics, benefits and efficacy
of the Mobile  Assistant(R)  series and the Company's other  products,  of which
there can be no assurance.

COMPETITION

           The computer  industry is intensely  competitive and is characterized
by rapid technological  advances,  evolving industry standards and technological
obsolescence.  Many of the Company's  current  competitors have longer operating
histories and greater financial, technical, sales, marketing and other resources
than the Company.  Several other  companies are engaged in the  manufacture  and
development of body-mounted or hand-held computing systems that compete with the
Mobile  Assistant(R)  series,  including  Computing  Devices  International,   a
division of Ceridian Corporation,  ViA Inc., Texas Microsystems,  Telxon, Norand
and Teltronics,  Inc., a subsidiary of Interactive Solutions, Inc., Raytheon and
a  consortium  of Litton and TRW.  Personal  digital  assistants  and laptop and
notebook  computers  also are  products  that could  compete  against the Mobile
Assistant(R) in applications where hands-free,  voice-activated operation is not
required. Many of these computers are manufactured by major domestic and foreign
computer manufacturers which possess far more resources than the Company and can
be expected to compete  vigorously  with the Company for the market at which the
Mobile Assistant(R) is directed. In addition, new and competing technologies are
being  developed  in  hands-free  mobile  computing  systems.  There  can  be no
assurance  that the  Company  will be able to compete  successfully  against its
competitors,  that it will have the working  capital needed to  incorporate  the
constant  technological  advances  in  its  products  or  that  the  competitive
pressures  faced  by  the  Company  will  not  adversely  affect  its  financial
performance.

DEPENDENCE UPON SUPPLIERS

           To prepare the Mobile  Assistant(R)  P-133 for delivery to customers,
the Company purchases system components from several suppliers, who manufacture,
assemble,  integrate and test these components.  The Company then combines those
components and performs system tests prior to shipping.  Certain  components are
currently  purchased from single  suppliers.  The Company expects that the MA IV
will be assembled,


                                       -6-





integrated  and tested by third  party.  The Company has  entered  into  written
agreements with its suppliers for batteries, head-mounted displays and computing
units.  Although the Company  believes there are multiple sources for many parts
and components,  the Company currently depends heavily on its current suppliers.
Although  management  believes  that  the  Company  could  adapt  to any  supply
interruptions,  such occurrences could necessitate  changes in product design or
assembly  methods  for the Mobile  Assistant(R)  series and cause the Company to
experience  temporary  delays or  interruptions in supply while such changes are
incorporated.  Further,  because the order time for certain components may range
up to approximately  three months,  the Company also could experience  delays or
interruptions  in  supply in the event the  Company  is  required  to find a new
supplier for any of these  components.  Any  disruptions  in supply of necessary
parts and  components  from the Company's  key  suppliers  could have a material
adverse effect on the Company's  results of operations.  Any future  shortage or
limited  allocation  of  components  for the  Mobile  Assistant(R)  could have a
material adverse effect on the Company.

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

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

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

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


                                       -7-





Xybernaut(R)  trademarks on the  Principal  Register of the United States Patent
and Trademark Office ("Patent Office").

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

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

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


                                       -8-





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

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

DEPENDENCE UPON AND NEED FOR KEY PERSONNEL; LIMITED MANAGEMENT TEAM

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



                                       -9-





CUSTOMER CONCENTRATION

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

RAPID TECHNOLOGICAL CHANGE AND RISK OF OBSOLESCENCE

           The  market  for  computer   products  is   characterized   by  rapid
technological  advances,  evolving  industry  standards,  changes  in  end  user
requirements  and  frequent  new product  introductions  and  enhancements.  The
introduction  of products  embodying new  technologies  and the emergence of new
industry  standards  could render the Company's  existing  products and products
currently under  development  obsolete and  unmarketable.  The Company's success
will depend upon its  ability to enhance  its current  products  and develop and
successfully  introduce and sell new products that keep pace with  technological
developments and respond to evolving end user  requirements.  Any failure by the
Company to anticipate or respond adequately to technological developments or end
user  requirements,   or  any  significant  delays  in  product  development  or
introduction, could damage the Company's competitive position in the marketplace
and reduce  revenues.  The  Company  expects to increase  the use of  additional
external and internal resources in the near term to meet these challenges. There
can be no assurance that the Company will be successful in hiring,  training and
retaining qualified product  development  personnel to meet its needs. There can
be no assurance  that the Company will be successful in developing and marketing
new  products  or  product  enhancements  on a  timely  basis.  Any  failure  to
successfully develop and market new products and product enhancements would have
a material adverse effect on the Company's results of operations.

YEAR 2000 ISSUES

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



                                      -10-





INDUSTRY CYCLICALITY

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

EFFECT OF POSSIBLE NON-CASH FUTURE CHARGE

           As a condition to the Company's  initial public offering (the "IPO"),
certain of the Company's  stockholders,  primarily officers and directors,  have
been  required to deposit an aggregate of 1,800,000  shares of Common Stock into
an escrow account (the "Escrowed  Shares").  The Escrowed  Shares are subject to
incremental  release  over a three-year  period only in the event the  Company's
gross  revenues and earnings  (loss) per share for the 12-month  periods  ending
September  30, 1997,  1998 and 1999 equal or exceed  certain  gross  revenue and
earnings (loss) per share targets.  If such per share targets are not met in any
of the  relevant  12-month  periods  (and the price of the Common Stock does not
meet or exceed the price described below),  the Escrowed Shares will be returned
to the Company in amounts which have been agreed upon between the Representative
and the Company for each period and canceled. In addition to the foregoing,  all
the then  Escrowed  Shares will be released to the  stockholders  if the closing
price of the Common Stock as reported on The Nasdaq  SmallCap  Market  following
this offering equals or exceeds $11.00 for 25 consecutive trading days or 30 out
of 35 consecutive  trading days during the period ending  September 30, 1999. In
the event any Escrowed  Shares held by officers,  employees and  consultants are
released, the difference between the initial offering price and the market value
of  such  shares  at the  time  of  release  will  be  deemed  to be  additional
compensation expense to the Company. Assuming the price of Common Stock is equal
to or greater than the initial offering price of the shares at the Company's IPO
(of which there can be no assurance),  the release of the Escrowed  Shares would
result  in an  earnings  charge  that  would  have the  effect  of  reducing  or
eliminating  any  earnings  per share and could  have a  negative  effect on the
market price for the Common  Stock.  The  earnings per share target  calculation
will be based on the average number of shares issued and outstanding during each
period but excludes  shares issued  pursuant to a unit purchase  option  granted
pursuant to the IPO,  extraordinary items or compensation expense charged to the
Company  related to the release of the Escrowed  Shares.  The stock and earnings
targets for escrow  release for September 30, 1997 were not achieved and 300,000
shares were canceled from the escrow pool, which resulted in a reduction of 2.1%
of the Company's outstanding shares of Common Stock. Given the expected start of
full-scale  production of the MA IV in the quarter ending December 31, 1998, the
Company's  management  believes  that it is  likely  that  the  Company's  gross
revenues  and  allowable  losses will not meet the  Performance  Targets for the
12-month  period  ending  September  30, 1998.  Accordingly,  the release of the
escrow  shares  for this  period is only  likely if the  stock  price  equals or
exceeds  $11.00  for 25  consecutive  trading  days or 30 out of 35  consecutive
trading days prior to September 30, 1998. If conditions  are not met for release
from  escrow,  then  750,000  shares of stock will be returned to the Company on
September  30,  1998  and  canceled,  resulting  in  no  earnings  impact  and a
commensurately lower number of outstanding shares.

CONTROL BY EXISTING STOCKHOLDERS

           Following this offering, the Company's executive officers,  directors
and  principal   stockholders   will,  in  the   aggregate,   beneficially   own
approximately  29.3% of the Company's  outstanding shares of Common Stock. These
stockholders,  if acting  together,  will be able to  effectively  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 22,009,108 shares of Common Stock that will be
outstanding  or  registered  for sale  upon  the  completion  of this  offering,
11,484,031 will be freely tradeable without restriction or further  registration
under the Securities Act. Such number includes  3,846,429 shares of Common Stock
distributed in the IPO,  1,958,984  shares of Common Stock registered and issued
upon  conversion  of the Series A Preferred  Stock,  3,172,239  shares of Common
Stock  registered  and issued upon  conversion of the Series B Preferred  Stock,
2,340,938  shares of Common Stock  registered in connection  with the April 1998
Private  Equity Line of Credit  Private  Placement,  and the 165,441  additional
shares of Common Stock  registered in this  offering.  The remaining  10,525,077
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 one or more other exemptions under the Securities Act (including Rule 144).
Rule 144, as  amended,  permits  sales of  restricted  securities  by any person
(whether or not an  affiliate)  after one year,  at which time sales can be made
subject  to  the  Rule's   existing   volume  and  other   limitations   and  by
non-affiliates   without  adhering  to  Rule  144's  existing  volume  or  other
limitations  after two years.  Future sales of substantial  amounts of shares in
the  public  market,  or the  perception  that such  sales  could  occur,  could
adversely  affect the price of the shares in any market that may develop for the
trading of such shares. In addition, pursuant to the terms of agreements entered
into  pursuant to the IPO, the holders of  9,905,437  shares of Common Stock may
not sell or dispose of their  shares of Common Stock until July 18, 1998 without
prior written consent of the  representative  of the underwriter in the IPO (the
"Representative").

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.


                                      -12-





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 C Preferred Stock
are issued and outstanding.  The authorized and unissued  Preferred Stock may be
issued  with  voting,  conversion  or other  terms  determined  by the  Board of
Directors  which  could be used to  delay,  discourage  or  prevent  a change of
control of the Company. Such terms could include,  among other things,  dividend
payment  requirements,  redemption  provisions,  preferences as to dividends and
distributions  and preferential  voting rights.  The issuance of Preferred Stock
with such rights could have the effect of limiting stockholder  participation in
certain  transactions  such as mergers or tender offers and could  discourage or
prevent a change in  management  of the  Company.  The  Company  has no  present
intention  to  issue  any  additional   Preferred  Stock.  See  "Description  of
Securities -- Preferred Stock."

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

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

                            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,  there are
20,887,915  shares of Common  Stock and 375 shares of Series C  Preferred  Stock
issued and outstanding.  The Company currently has reserved  6,546,692 shares of
Common Stock for issuance pursuant to outstanding options and warrants.

THE PRIVATE PLACEMENT

           On May 22,  1998 (the  "Closing  Date"),  the Company  consummated  a
private  placement  of  110,294  shares of Common  Stock at a price of $3.40 per
share and 375 shares of Series C Preferred  Stock at a price of $1,000 per share
for an aggregate purchase price of $750,000.  The shares of Common Stock and the
shares of Series C Preferred  Stock were issued by the Company in reliance  upon
the provisions of Section 4(2) and Regulation D of the Securities Act.

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 C PREFERRED STOCK

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


                                      -15-





           Dividends.  The holders of the shares of Series C 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 C 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 C 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 C  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 C
Preferred  Stock  the  full  Liquidation  Preference  plus  accrued  and  unpaid
dividends  to which they  respectively  shall be  entitled,  the  holders of the
Series C  Preferred  Stock  together  with the  holders  of any other  series of
Preferred  Stock ranking on a parity with the Series C 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 C
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 C Preferred Stock shall have
conversion  rights as follows:  (i) no shares of Series C Preferred Stock may be
converted  prior to August  15,  1998;  (ii) at any time after  August 15,  1998
through  November 14, 1998,  up to  twenty-five  (25%)  percent of the shares of
Series C Preferred Stock then outstanding may be converted, at the option of the
holders thereof;  and (iii) thereafter,  on November 15, 1998, February 15, 1999
and May 15,  1999,  an  additional  twenty-five  (25%)  percent of the shares of
Series C Preferred Stock then outstanding may be converted,  on a cumulative and
pro rata basis,  at the option of the holders  thereof.  The number of shares of
fully-paid  and  nonassessable  Common  Stock  into which each share of Series C
Preferred Stock may be converted shall be determined by dividing the Liquidation
Preference by an amount (the "Conversion Price") equal to the lesser of (A) 100%
of the average  closing bid price of the Common  Stock as reported on the Nasdaq
SmallCap  Market or any  successor  exchange in which the Common Stock is listed
for the five trading days preceding the date on which the holder of the Series C
Preferred  Stock has  telecopied  a notice of  conversion  to the  Company  (the
"Conversion Date") and (B) $4.00.

           In the event the shares of Series C 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 C 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.


                                      -16-





           No fractional  shares of Common Stock shall be issued upon conversion
of the Series C 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 C 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 C Preferred Stock, the shares of Series
C 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 C Preferred Stock,  shares of Series C 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 May 15, 2000, the holders of the Series C Preferred Stock shall be
required to convert all of their outstanding  shares of Series C Preferred Stock
into shares of Common Stock.  Until converted,  the Company shall be entitled to
redeem shares of Series C 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 C 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 C
Preferred Stock.

           Redemption.  At any time after May 15, 1998,  the Company may, at the
option of the Board of Directors, redeem up to 100% of the outstanding shares of
the Series C 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 below  $3.40.  The  Company  shall give  written  notice by
telecopy,  to the holder of Series C Preferred Stock to be redeemed at least one
business  day  after  receipt  of the  notice  of  conversion  prior to the date
specified for redemption (the  "Redemption  Date").  Such notice shall state the
Redemption  Date, the Redemption Price (as hereinafter  defined),  the number of
shares of Series C Preferred Stock of such holders to be redeemed and shall call
upon such  holders to  surrender  to 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 C  Preferred  Stock are to be  redeemed,  the
redemption  shall be pro rata among the holders of Series C Preferred  Stock and
subject to such other provisions as may be determined by the Board of Directors.
The  Redemption  Date  shall be no more than 10 days  after  receipt  of written
notice from the Company. If the Company fails to pay the Redemption Price on the
Redemption  Date,  the Company shall pay to the holder a penalty in an amount in
cash equal to 2% percent of the Redemption  Price to be paid on such  Redemption
Date. If the Company fails to pay the Redemption  Price on the Redemption  Date,
the  holder  shall  have the  right to  convert  the  Series C  Preferred  Stock
previously presented to the Company and not redeemed. The Company shall have the
right to redeem  the  Series C  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 C 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 C 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.


                                      -17-





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

           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 C 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 C 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 C  Preferred
Stock of the Company where such action would be in violation of applicable law.

           Voting  Rights.  Except as otherwise  required by law, the holders of
the  Series C  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 C Preferred Stock
shall be  redeemed,  the shares so  redeemed  shall be deemed to be  permanently
canceled and shall not resume the status of  authorized  but unissued  shares of
Series C Preferred Stock.

           Ranking;  Changes  Affecting  Series C Preferred  Stock. The Series C
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 C 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 C Preferred Stock and (iii) rank on a pari passu basis with
the Series C and any other series of Preferred Stock of the Company.

           So long as any shares of Series C  Preferred  Stock are  outstanding,
the  Company  shall  not (i)  alter or  change  any of the  powers  preferences,
privileges,  or  rights  of the  Series C  Preferred  Stock;  or (ii)  amend the
provisions of the Certificate of Designation affecting the ranking of the Series
C 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 C Preferred Stock, as to changes affecting the
Series C Preferred Stock.

           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,  Series B
Preferred  Stock and  Series C  Preferred  Stock.  There are no other  shares of
Preferred Stock outstanding, and the Company currently has no plans to issue any

                    DELAWARE BUSINESS COMBINATION PROVISIONS

           As a Delaware  corporation,  the  Company  is subject to Section  203
("Section  203") of the Delaware  General  Corporation  Law (the "DGCL"),  which
regulates large accumulations of shares,  including those made by tender offers.
Section 203 may have the effect of significantly  delaying a purchaser's ability
to acquire  the  entire  interest  in the  Company  if such  acquisition  is not
approved by the Company's Board of Directors.  In general,  Section 203 prevents
an "Interested Stockholder" (defined generally as a person with 15% or more of a
corporation's   outstanding   voting   stock)  from   engaging  in  a  "Business
Combination"  (defined  below)  with a  Delaware  corporation  for  three  years
following the date such person became an Interested Stockholder. For purposes of
Section  203,  the term  "Business  Combination"  is defined  broadly to include
mergers  and  certain  other  transactions  with  or  caused  by the  Interested
Stockholder,  sales or other dispositions to the Interested  Stockholder (except
proportionately  with the  corporation's  other  stockholders)  of assets of the
corporation or a subsidiary  equal to 10% or more of the aggregate  market value
of the corporation's  consolidated assets or its outstanding stock; the issuance
or transfer by the  corporation  or a subsidiary of stock of the  corporation or
such  subsidiary  to the  Interested  Stockholder  (except  for  transfers  in a
conversion or exchange or a pro-rata distribution or certain other transactions,
none of which increase the Interested  Stockholder's  proportionate ownership of
any class or series of the corporation's or such subsidiary's stock); or receipt
by  the  Interested  Stockholder  (except  proportionately  as  a  stockholder),
directly or indirectly,  of any loans,  advances,  guarantees,  pledges or other
financial benefits provided by or through the corporation or a subsidiary.

           The three-year moratorium imposed on Business Combinations by Section
203 does not apply if: (a) prior to the date on which a  stockholder  becomes an
Interested  Stockholder,  the Company's  Board of Directors  approves either the
Business  Combination or the transaction that resulted in the person becoming an
Interested  Stockholder,   (b)  the  Interested  Stockholder  owns  85%  of  the
corporation's voting stock upon consummation of the transaction that made him or
her an Interested  Stockholder  (excluding from the 85% calculation shares owned
by  directors  who are also  officers  of the  corporation  and  shares  held by
employee  stock plans  which do not permit  employees  to decide  confidentially
whether  to accept a tender or  exchange  offer);  or (c) on or after the date a
person  becomes an  Interested  Stockholder,  the  Company's  Board of Directors
approves  the Business  Combination,  and it is also  approved at a  stockholder
meeting  by  two-thirds  of  the  voting  stock  not  owned  by  the  Interested
Stockholder.

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

                              PLAN OF DISTRIBUTION

           The  distribution  of the Shares by the Selling  Stockholders  may be
effected from time to time in one or more transactions  (which may involve block
transactions),  in special offerings,  exchange  distributions  and/or secondary
distributions,  in  negotiated  transactions,  in  settlement  of short sales of
Shares, or a combination or such methods of sale, at market prices prevailing at
the time of sale,  at prices  related  to such  prevailing  market  prices or at
negotiated prices. Such transactions may be effected on a stock exchange, on the
over-the-counter  market or privately.  The Selling Stockholders may effect such
transactions by selling the Shares to or through


                                      -19-





broker-dealers,  and such broker-dealers may receive compensation in the form of
underwriting discounts, concessions or commissions from the Selling Stockholders
for whom they may act as agent (which compensation may be in excess of customary
commissions). Without limiting the foregoing, such brokers may act as dealers by
purchasing any and all of the Shares covered by this Prospectus either as agents
for others or as principals for their own accounts and reselling such securities
pursuant to this Prospectus.  The Selling Stockholders and any broker-dealers or
other persons acting on the behalf of parties that participate with such Selling
Stockholders in the  distribution of the Shares may be deemed to be underwriters
and any  commissions  received  or profit  realized by them on the resale of the
Shares may be deemed to be  underwriting  discounts  and  commissions  under the
Securities Act. As of the date of this  Prospectus,  the Company is not aware of
any agreement, arrangement or understanding between any broker or dealer and the
Selling Stockholders with respect to the offer or sale of the Shares pursuant to
this Prospectus.

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

           Each of the  Selling  Stockholders  may from time to time  pledge the
Shares  owned  by it to  secure  margin  or  other  loans  made to such  Selling
Stockholder.  Thus,  the  person or entity  receiving  the  pledge of any of the
Shares may sell them, in a foreclosure sale or otherwise,  in the same manner as
described above for such Selling Stockholder.

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

           Pursuant to the Registration  Rights Agreements,  the Company and the
Selling  Stockholders  have  agreed to  indemnify  each  other  against  certain
liabilities,  including  liabilities under the Securities Act. The Company shall
bear  customary  expenses  incident  to the  registration  of the Shares for the
benefit of the Selling  Stockholders in accordance with such  agreements,  other
than underwriting discounts and commissions directly attributable to the sale of
such securities by or on behalf of the Selling Stockholders.

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

                 INDEMNIFICATION FOR SECURITIES ACT LIABILITIES

           Section  145 of the DGCL  provides,  in general,  that a  corporation
incorporated  under the laws of the State of Delaware,  such as the  registrant,
may  indemnify  any person who was or is a party or is  threatened  to be made a
party to any threatened,  pending or completed action, suit or proceeding (other
than a derivative action by or in the right of the corporation) by reason of the
fact that such  person is or was a director,  officer,  employee or agent of the
corporation,  or is or was  serving  at the  request  of  the  corporation  as a
director,  officer,  employee or agent of another  enterprise,  against expenses
(including  attorneys'  fees),  judgments,  fines and amounts paid in settlement
actually and reasonably  incurred by such person in connection with such action,
suit or  proceeding  if such  person  acted in good  faith and in a manner  such
person reasonably believed to be in or not opposed to the


                                      -20-





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

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

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

                                  LEGAL MATTERS

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

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

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

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


                                     II - 1





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;



                                     II - 2





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

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

            Insofar  as  indemnification   for  liabilities  arising  under  the
Securities  Act of 1933 (the "Act") may be permitted to directors,  officers and
controlling  persons of the small  business  issuer  pursuant  to the  foregoing
provisions, or otherwise, the small business issuer has been advised that in the
opinion of the  Securities  and  Exchange  Commission  such  indemnification  is
against public policy as expressed in the Act and is, therefore, unenforceable.

            In  the  event  that  a  claim  for  indemnification   against  such
liabilities  (other  than the payment by the small  business  issuer of expenses
incurred  or paid by a  director,  officer  or  controlling  person of the small
business issuer in the successful defense of any action,  suit or proceeding) is
asserted by such director,  officer or controlling person in connection with the
securities  being  registered,  the small  business  issuer will,  unless in the
opinion of its counsel  the matter has been  settled by  controlling  precedent,
submit  to a  court  of  appropriate  jurisdiction  the  question  whether  such
indemnification  by it is against  public policy as expressed in the  Securities
Act and will be governed by the final adjudication of the issue.

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