                                  RISK FACTORS

     BEFORE YOU BUY SHARES OF OUR COMMON  STOCK,  YOU SHOULD BE AWARE THAT THERE
ARE VARIOUS RISKS  ASSOCIATED  WITH THAT  PURCHASE,  INCLUDING  THOSE  DESCRIBED
BELOW.  YOU SHOULD CONSIDER  CAREFULLY THESE RISK FACTORS,  TOGETHER WITH ALL OF
THE OTHER  INFORMATION IN THIS PROSPECTUS AND THE DOCUMENTS WE HAVE INCORPORATED

BEFORE YOU DECIDE TO PURCHASE SHARES OF OUR COMMON STOCK.

              -----------------------------------------------------
                 RISKS ASSOCIATED WITH OUR HISTORY OF LOSSES AND
                             FUTURE NEED FOR CAPITAL
              -----------------------------------------------------

WE HAVE A HISTORY OF LOSSES AND, IF WE DO NOT ACHIEVE PROFITABILITY,  WE MAY NOT
BE ABLE TO CONTINUE OUR BUSINESS IN THE FUTURE.

     Our research,  development, sales, marketing and general and administrative
expenses  have  resulted in  significant  losses and are expected to continue to
result in significant  losses for the foreseeable  future.  We have incurred the
following losses since 1996:

            Fiscal years ended:
              o  December 31, 1996        $5,298,633
              o  December 31, 1997       $10,051,757
              o  December 31, 1998       $13,001,338
              o  December 31, 1999       $16,697,413
              o  December 31, 2000       $24,185,222

            Fiscal quarters ended:
              o  March 31, 2001          $ 5,936,589
              o  June 30, 2001           $ 8,453,995

WE COULD BE REQUIRED TO CUT BACK OR STOP OPERATIONS IF WE ARE UNABLE TO RAISE OR
OBTAIN NEEDED FINANCING.

     The research, development,  commercialization,  manufacturing and marketing
of our products will likely require financial  resources which are significantly
in  excess of those  presently  available  to us. If we are not able to  arrange
financing  or other third party  arrangements  on  acceptable  terms,  we may be
unable to fully  develop  and  commercialize  any of our  products  and could be
required to cut back or stop operations.


                                       2


                ----------------------------------------------------
                  RISKS ASSOCIATED WITH THE INDUSTRY IN WHICH WE
                                      OPERATE
                ----------------------------------------------------

OUR FUTURE REVENUES AND ABILITY TO PRODUCE NEW PRODUCTS DEPEND  SUBSTANTIALLY ON
THE SUCCESS OF THE MOBILE ASSISTANT(R) SERIES.

     The Mobile Assistant series is our principal product,  and our success will
depend  to a large  extent  upon its  commercial  acceptance,  which  cannot  be
assured. We have signed an agreement with IBM to design, develop and manufacture
the computer portion of Xybernaut's next generation of wearable computer systems
and we  have  recently  begun  shipments  of this  product  and  the  MA(R)  TC.
Additional  product  development  will result in a  significant  increase in our
research   and   development   expenses   that  may  be   unrecoverable   should
commercialization  of new products  prove  unsuccessful.  We also could  require
additional  funding if research  and  development  expenses  are greater than we
anticipate.  As with most high  technology  products,  new  models of the Mobile
Assistant  series  must be  introduced  periodically  for our  company to remain
competitive. There can be no assurance that these new models can be successfully
developed or will be commercially accepted.

WE MAY HAVE TO LOWER PRICES OR SPEND MORE MONEY TO EFFECTIVELY  COMPETE  AGAINST
COMPANIES  WITH GREATER  RESOURCES THAN US, WHICH COULD RESULT IN LOWER REVENUES
AND/OR PROFITS.

     The success of our  products in the  marketplace  depends on many  factors,
including  product  performance,   price,  ease  of  use,  support  of  industry
standards,  competing technologies and customer support and service. Given these
factors we cannot assure you that we will be able to compete  successfully.  For
example,  if our  competitors  offer lower  prices,  we could be forced to lower
prices  which  could  result in reduced or  negative  margins  and a decrease in
revenues.  If we do not lower  prices we could lose sales and market  share.  In
either  case,  if we are unable to compete  against our main  competitors  which
include established companies like Computing Devices  International,  a division
of Ceridian Corporation,  ViA Inc., Texas Microsystems,  Telxon, Symbol, Norand,
Raytheon,  and others, we would not be able to generate  sufficient  revenues to
grow our company or reverse our history of losses.

     In  addition,  we may have to spend more money to  effectively  compete for
market share,  including funds to expand our infrastructure,  which is a capital
and time intensive process.  Further,  if other companies choose to aggressively
compete  against  us, we may have to reduce  our  prices and spend more money on
advertising, promotion, trade shows, product development, marketing and overhead
expenses, hiring and retaining personnel, and developing new technologies. These
lower prices and higher expenses would adversely affect our net income.

CURRENCY  FLUCTUATIONS,  ESPECIALLY  IN THE JAPANESE  YEN AND GERMAN  MARK,  MAY
SIGNIFICANTLY INCREASE OUR EXPENSES AND AFFECT OUR RESULTS OF OPERATIONS.

     The exchange rates for some local  currencies in countries where we operate
may  fluctuate in relation to the U.S.  dollar.  Such  fluctuations  may have an
adverse effect on our  competitive  position as well as our expenses,  revenues,
earnings,  assets or liabilities  when local currencies are translated

                                       3


into U.S. dollars. We have significant  operations in Asia, in particular Japan,
and Europe, in particular Germany.  Also, we are party to supplier  arrangements
with  several  companies  in Japan and Europe for the  production  of the Mobile
Assistant series. Our foreign  operations,  including payments to our suppliers,
are typically  funded in the local  currencies.  Any changes in the value of the
U.S. dollar against these currencies could result in an increase in our reported
expenses or inventory  costs or a decrease in our reported  revenues  which,  if
substantial, could have a material adverse effect on our financial condition and
results of operations.

           ----------------------------------------------------------
                              RISK ASSOCIATED WITH
                      OUR INTERNAL OPERATIONS AND POLICIES
           ----------------------------------------------------------

SINCE WE DO NOT INTEND TO  DECLARE  DIVIDENDS  IN THE  FORESEEABLE  FUTURE,  THE
RETURN ON YOUR INVESTMENT  WILL DEPEND UPON  APPRECIATION OF THE MARKET PRICE OF
YOUR SHARES.

     We have  never  paid  any  dividends  on our  common  stock.  Our  board of
directors  does not intend to declare any dividends in the  foreseeable  future,
but intends to retain all earnings,  if any, for use in our business operations.
As a result,  the return on your  investment  in Xybernaut  will depend upon any
appreciation  in the market  price of the common  stock.  The  holders of common
stock are entitled to receive dividends when, as and if declared by the board of
directors out of funds legally available for dividend  payments.  The payment of
dividends,  if any,  in the  future is  within  the  discretion  of our board of
directors and will depend upon our earnings,  capital requirements and financial
condition, and other relevant factors.

      ---------------------------------------------------------------------
               RISKS WHICH MAY DILUTE THE VALUE OF YOUR XYBERNAUT
                SHARES OR LIMIT THE EFFECT OF THEIR VOTING POWER
      ---------------------------------------------------------------------

THE PRICE OF OUR COMMON STOCK IS HIGHLY VOLATILE.

     The price of our common  stock is highly  volatile.  During the period from
January 1, 2000 to August 27,  2001 the  closing  price of our common  stock has
ranged from a high of $23.75 to a low of $1.22.  Following periods of volatility
in  the  market  price  of  a  company's  securities,  securities  class  action
litigation  has  often  been  instituted  against  such a  company.  If  similar
litigation were instituted  against us, it could result in substantial costs and
a diversion of our  management's  attention and  resources,  which could have an
adverse effect on our business.  The volatile  fluctuations  of the market price
are based on (1) the  number of shares in the  market at the time as well as the
number of shares we may be  required  to issue in the  future,  compared  to the
market demand for our shares;  (2) our performance  and meeting  expectations of
our performance, including the development and commercialization of our products
and proposed  products;  (3) market  conditions for technology  companies in the
small capitalization sector; and (4) general economic and market conditions.

                                       4


OUR EXECUTIVE  OFFICERS,  DIRECTORS AND PRINCIPAL  STOCKHOLDERS,  TOGETHER,  MAY
EXERCISE CONTROL OVER ALL MATTERS SUBMITTED TO A VOTE OF STOCKHOLDERS.

     As of May  18,  2001,  our  executive  officers,  directors  and  principal
stockholders  beneficially  owned, in the aggregate,  approximately 11.7% of our
outstanding shares of common stock. These stockholders,  if acting together, may
be  able  to  effectively   control  most  matters  requiring  approval  by  our
stockholders. The voting power of these stockholders under certain circumstances
could  have the  effect  of  delaying  or  preventing  a change  in  control  of
Xybernaut.

WE HAVE  12,868,762  SHARES OF OUR COMMON STOCK  RESERVED  FOR FUTURE  ISSUANCES
WHICH CAN SUBSTANTIALLY DILUTE THE VALUE OF YOUR XYBERNAUT COMMON STOCK.

     The  issuance  of  reserved  shares  would  dilute the equity  interest  of
existing  stockholders and could have a significant adverse effect on the market
price of our common stock.  As of August 27, 2001, we had  12,868,762  shares of
common stock reserved for possible  future  issuances upon conversion of options
and warrants. These options and warrants are convertible into or exercisable for
shares of common stock at prices that may represent discounts from future market
prices of the common  stock.  The  exercise of these  options or warrants  could
result in substantial  dilution to existing holders of common stock. The sale of
the common  stock  acquired  at a discount  could have a negative  impact on the
trading  price of the common  stock and could  increase  the  volatility  in the
trading price of the common stock.  See the section  entitled  "Dilution"  for a
summary of the number of shares  which  could be issued upon  conversion  of the
outstanding preferred stock at various market prices.

     In  addition,  we may seek  additional  financing  which may  result in the
issuance of  additional  shares of our capital  stock  and/or  rights to acquire
additional  shares of our capital stock.  Those additional  issuances of capital
would result in a reduction of your percentage interest in Xybernaut.

ANTI-TAKEOVER  MEASURES IN OUR  CERTIFICATE  OF  INCORPORATION  COULD  ADVERSELY
AFFECT THE VOTING POWER OF THE HOLDERS OF THE COMMON STOCK.

     Our certificate of incorporation  authorizes anti-takeover measures such as
the authority to issue "blank check"  preferred stock and the staggered terms of
the members of our board of directors.  Those  measures could have the effect of
delaying,  deterring or preventing a change in control without any action by our
stockholders.  In addition,  issuance of preferred  stock,  without  stockholder
approval,  on  those  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.

                INFORMATION REGARDING FORWARD-LOOKING STATEMENTS

     This prospectus contains certain  forward-looking  statements which involve
substantial  risks  and  uncertainties.  These  forward-looking  statements  can
generally be identified because the context of the statement includes words such
as "may," "will,"  "except,"  "anticipate,"  "intend,"  "estimate,"  "continue,"
"believe,"  or other  similar  words.  Similarly,  statements  that describe our
future plans,  objectives  and goals are also  forward-looking

                                       5


statements.  Our factual  results,  performance  or  achievements  could  differ
materially from those expressed or implied in these  forward-looking  statements
as a result of certain  factors,  including  those listed in "Risk  Factors" and
elsewhere in this prospectus.

                  WHERE YOU CAN FIND MORE INFORMATION ABOUT US

     We file annual,  quarterly and special reports,  proxy statements and other
information  with the SEC.  You may  read and copy any  document  we file at the
SEC's  public  reference  rooms in  Washington,  D.C.,  New  York,  New York and
Chicago, Illinois. Please call the SEC at 1-800-SEC-0330 for further information
on the public  reference rooms. Our SEC filings are also available to the public
over the Internet at the SEC's Website at "http://www.sec.gov."

     We have filed with the SEC a registration statement on Form S-3 to register

and, as  permitted  by the SEC's  rules,  does not  contain all the  information
included in the registration statement.  For further information with respect to
us and our common stock, you should refer to the  registration  statement and to
the exhibits and schedules filed as part of the registration  statement, as well
as the documents discussed below.

     The SEC allows us to  "incorporate  by reference"  the  information we file
with them,  which means that we can  disclose  important  information  to you by
referring you to those documents.  The information  incorporated by reference is
an important part of this  prospectus,  and information  that we file later with
the SEC will automatically update or supersede this information.

     This  prospectus  may contain  summaries of  contracts or other  documents.
Because they are summaries,  they will not contain all of the  information  that
may be important to you. If you would like complete information about a contract
or  other  document,  you  should  read  the copy  filed  as an  exhibit  to the
registration   statement  or  incorporated  in  the  registration  statement  by

                                 USE OF PROCEEDS

      The selling stockholders are selling all of the shares covered by this
prospectus for their own accounts. Accordingly, we will not receive any proceeds
from the resale of the shares.

      We will receive proceeds, if any, from the exercise of warrants. We will
use those proceeds, if any, for working capital and general corporate purposes.

     We will  bear  the  expenses  relating  to this  registration,  other  than
discounts and commissions, which will be paid by the selling stockholder.

                                    DILUTION

     As of August 27, 2001, we had issued and outstanding  52,758,624  shares of
common stock. At that date, there were an additional 12,868,762 shares of common
stock reserved for possible future issuances as follows:

     o    options to  purchase  6,071,719  shares at an exercise  price  between
          $1.21 and $23.38 per share.  We have  registered  the shares  issuable
          upon exercise of the options under the Securities Act;

     o    warrants to purchase  5,270,754  shares at a price  between  $2.00 and
          $18.00  per  share.  Of  the  5,270,754  shares,  we  have  previously
          registered a total of 4,332,393 shares issuable upon exercise of these
          warrants.  This  prospectus  covers an  additional  570,861  shares of
          common stock issuable upon exercise of warrants,  which shares will be
          freely tradable without  restriction  (subject to prospectus  delivery
          requirements) on the effective date of the registration statement. The
          remaining 367,500 shares will be deemed to be "restricted  securities"
          when issued; and

     o    1,526,289 shares issuable upon exercise of options under the Company's
          stock  incentive  plans  which have not been  granted as of August 27,
          2001.  We have  registered  the shares  issuable  upon exercise of the
          options.

     The shares which will be deemed  "restricted  securities" may be sold under
Rule 144.  Rule 144  permits  sales of  "restricted  securities"  by any person,
whether or not an affiliate of the issuer,  after a one year holding period.  At
that time, sales can be made subject to the Rule's volume and other  limitations
and after two years by  non-affiliates  without adhering to Rule 144's volume or
other  limitations.  In general,  an  "affiliate"  is a person with the power to
manage and direct our policies.  The SEC has stated that,  generally,  executive
officers and directors of an entity are deemed affiliates of the issuing entity.

     The common stock has the material  rights and  obligations  discussed below
and under the section  entitled  "Description  of Securities." We have filed the
agreements relating to these rights and obligations with the SEC. We urge you to
read them in their entirety.

     Eva  Holdings  Limited  acquired  its  shares of common  stock in a private
placement  transaction  entered  into on July 31,  2001.  Under the terms of the
common stock and warrant purchase agreement between Eva Holdings Limited and us,
we agreed to sell  1,324,503  shares of our common stock at a price of $3.02 per
share,  representing  an  approximate  10% discount to the closing  price of the
shares on the day preceding the finalization of negotiations, for gross proceeds
of $4,000,000.  We also issued warrants to purchase 331,126 shares of our common
stock at $4.53 per share. The warrants are exercisable for a

                                       8


period  of 5 years  from  the  date of  issuance.  We may call up to 100% of the
warrants if the common  stock  trades at a price equal to or greater  than $6.50
per share for 5 consecutive  trading days. In connection with our sale of common
stock pursuant to the common stock and warrant  purchase  agreement,  we entered
into a registration  rights agreement  pursuant to which, among other things, we
agreed to use our best efforts to (i) file a registration  statement to register
for resale  the shares of common  stock,  including  the shares of common  stock
issuable  upon  exercise  of the  warrants,  no later  than sixty days after the
closing date and (ii) cause such  registration  statement to become effective no
later than ninety days after the closing date.

     On July 31, 2001, DaVinci International Limited received cash in the amount
of $120,000 and warrants to purchase  39,735 shares of our common stock at $4.53
per share as a finders fee in connection with the private placement transaction.
The warrants are  exercisable for a period of 5 years from the date of issuance.
We may call up to 100% of the  warrants  if the common  stock  trades at a price
equal to or greater than $6.50 per share for 5 consecutive trading days.

     On April 18, 2001,  Texas  Instruments  Incorporated  received  warrants to
purchase  200,000  shares of our common  stock at $5.00 per share in  connection
with entering into a Speech Recognition  Software License Agreement with us. The
warrants are exercisable for a period of 5 years from the date of issuance.  The
warrant  provides  that we will use our  best  efforts  to cause a  registration
statement  for the shares of common  stock  underlying  such  warrants to become
effective no later then October 18, 2001.

     The  warrants  have  adjustment  provisions  for standard  dilution  events
including stock splits, stock dividends and similar transactions.

     Other than as indicated  above and as investors in private  placements  and
other  financings  for  our  common  stock,  the  selling  stockholders  are not
affiliated with us and has not had any material  relationship with us during the
past three years.

                            DESCRIPTION OF SECURITIES

GENERAL

     Our authorized capital stock consists of 80,000,000 shares of common stock,
par value $0.01 per share,  and 6,000,000  shares of preferred  stock, par value
$0.01 per share.  As of August 27,  2001,  we have  52,758,624  shares of common
stock issued and outstanding. We have reserved 12,868,762 shares of common stock
for issuance upon exercise of options and warrants.

COMMON STOCK

VOTING

     The  holders of our common  stock are  entitled  to one vote for each share
held  of  record  on all  matters  submitted  to a  vote  of  stockholders.  Our
certificate of  incorporation  and by-laws do not provide for cumulative  voting
rights in the election of directors.  Accordingly,  holders of a majority

                                       9


of the shares of common stock  entitled to vote in any election of directors may
elect all of the directors standing for election.

DIVIDENDS

     Holders of common stock are entitled to receive  ratably those dividends as
may be declared by our board of directors  out of funds  legally  available  for
that purpose.

RIGHTS ON LIQUIDATION

     In the event of our  liquidation,  dissolution  or winding  up,  holders of
common stock are entitled to share ratably in the assets remaining after payment
of liabilities.

PRE-EMPTIVE OR REDEMPTION RIGHTS

     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

     Our board of directors has the authority to issue up to 6,000,000 shares of
preferred  stock  from  time to time in one or more  series.  Our  board has the
authority to establish  the number of shares to be included in each series,  and
to fix the  designations,  powers,  preferences and rights of the shares of each
series and the  applicable  qualifications,  limitations  or  restrictions.  The
issuance of  preferred  stock may have the effect of delaying  or  preventing  a
change in control.  The issuance of preferred stock could decrease the amount of
earnings and assets  available for  distribution to the holders of common stock,
if any,  or could  adversely  affect  the rights and  powers,  including  voting
rights,  of the  holders of the common  stock.  In  certain  circumstances,  the
issuances  could have the effect of  decreasing  the market  price of the common
stock.

     As of the date of this  prospectus,  we have not  designated  any shares of
preferred stock other than the series A, B, C, D and E preferred  stock,  all of
which have been fully converted into common stock.

ANTI-TAKEOVER CONSIDERATIONS

     Our certificate of incorporation authorizes the issuance of up to 6,000,000
shares of $0.01 par value preferred  stock. The issuance of preferred stock with
such  rights  could have the effect of  limiting  stockholder  participation  in
certain  transactions  such as mergers or tender offers and could  discourage or
prevent a change in our  management.  We have no present  intention to issue any
additional preferred stock.

     We have a  classified  or  staggered  board of  directors  which  limits an
outsider's  ability  to  effect a rapid  change  of  control  of our  board.  In
addition, at the 1998 Annual Meeting of Stockholders held on September 24, 1998,
our stockholders approved measures to amend our certificate of incorporation and
by-laws, where applicable, to:

                                       10


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

     o    permit  only  the  President,  the Vice  Chairman  of our  board,  the
          Secretary  or our  board of  directors  to call  special  meetings  of
          stockholders  and to limit the  business  permitted to be conducted at
          such meetings to be brought before the meetings by or at the direction
          of our board;

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

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

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

     o    eliminate stockholder action by written consent;

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

     o    require an affirmative vote of 66 2/3% of the voting stock in order to
          amend  or  repeal  any  adopted   amendments  to  the  certificate  of
          incorporation and bylaws adopted at the meeting.

     Those measures combined with the ability of our board of directors to issue
"blank  check"  preferred  stock and the  staggered  terms of the members of our
board of directors, could have the effect of delaying, deterring or preventing a
change in control without any further action by the  stockholders.  In addition,
the issuance of preferred stock, without stockholder  approval, on such terms as
our board may determine,  could adversely affect the voting power of the holders
of the common stock, including the loss of voting control to others.

TRANSFER AGENT AND REGISTRAR

     Continental  Stock  Transfer  & Trust  Company  is our  Transfer  Agent and
Registrar for our common stock.

                                       11


                              PLAN OF DISTRIBUTION

     The selling  stockholder  and its pledgees,  donees,  transferees and other
subsequent  owners,  may offer its shares at various times in one or more of the
following transactions:

     o    on any U.S.  securities  exchange  on which  our  common  stock may be
          listed at the time of sale
     o    in the over-the-counter market
     o    in privately negotiated transactions
     o    in connection with short sales; or
     o    in a combination of any of the above transactions.

     The selling  stockholder may offer its shares of common stock at prevailing
market prices at the time of sale, at prices related to those prevailing  market
prices, at negotiated prices or at fixed prices.

     The selling  stockholder may also sell the shares under Rule 144 instead of
under this prospectus, if Rule 144 is available for those sales.

     The  transactions  in the shares covered by this prospectus may be effected
by one or more of the following methods:

     o    ordinary  brokerage  transactions and transactions in which the broker
          solicits purchasers;
     o    purchases by a broker or dealer as  principal,  and the resale by that
          broker or dealer  for its  account  under this  prospectus,  including
          resale to another broker or dealer;
     o    block  trades in which the broker or dealer  will  attempt to sell the
          shares as agent but may  position and resell a portion of the block as
          principal in order to facilitate the transaction; or
     o    negotiated  transactions  between selling  stockholders and purchasers
          without a broker or dealer.

     The selling  stockholder and any  broker-dealers or other persons acting on
the behalf of parties that  participate in the distribution of the shares may be
deemed to be underwriters. Any commissions or profits they receive on the resale
of the shares may be deemed to be underwriting  discounts and commissions  under
the Securities Act.

     As of the  date of this  prospectus,  we are not  aware  of any  agreement,
arrangement or understanding between any broker or dealer and any of the selling
stockholders  with  respect  to the  offer  or sale  of the  shares  under  this
prospectus.

     We have advised the selling  stockholder that during the time it is engaged
in  distributing  shares  covered by this  prospectus,  it must  comply with the
requirements  of the  Securities  Act and Rule 10b-5 and  Regulation M under the
Exchange Act. Under those rules and regulations, it:

     o    may not engage in any  stabilization  activity in connection  with our
          securities;

                                       12


     o    must furnish each broker  which  offers  common stock  covered by this
          prospectus  with the  number of copies  of this  prospectus  which are
          required by each broker; and
     o    may not bid for or purchase any of our securities or attempt to induce
          any person to purchase any of our  securities  other than as permitted
          under the Exchange Act.

                 INDEMNIFICATION FOR SECURITIES ACT LIABILITIES

     Section 145 of the  Delaware  General  Corporation  Law allows a company to
indemnify its  directors and officers  against  expenses,  judgments,  fines and
amounts paid in settlement under the conditions and limitations described in the
law. Our certificate of  incorporation  authorizes us to indemnify our officers,
directors and other agent to the fullest extent permitted under Delaware law.

     Our certificate of incorporation provides that a director is not personally
liable for monetary  damages to us or our  stockholders for breach of his or her
fiduciary  duties as a director.  A director will be held liable for a breach of
his or her duty of loyalty  to us or our  stockholders,  his or her  intentional
misconduct or willful violation of law, actions or in actions not in good faith,
an unlawful  stock  purchase  or payment of a dividend  under  Delaware  law, or
transactions from which the director derives an improper personal benefit.  This
limitation of liability does not affect the  availability of equitable  remedies
against the director including injunctive relief or rescission.

     We have  purchased a directors  and officers  liability  and  reimbursement
policy that covers  liabilities  of our  directors  and officers  arising out of
claims  based  upon acts or  omissions  in their  capacities  as  directors  and
officers.

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

                                  LEGAL MATTERS

     Jenkens & Gilchrist Parker Chapin LLP, New York, New York, a stockholder of
our  company,  will pass upon the  validity of the  securities  offered  hereby.
Martin Eric Weisberg,  Esq., a member of the firm, is our Secretary,  one of our
Directors, and a stockholder in our 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  will be made in respect of any claim, issue or matter
          as to which such  person  will have been  adjudged to be liable to the
          corporation  unless and only to the extent  that the Court of Chancery
          of the State of  Delaware  or any other court in which such action was
          brought  determines  such person is fairly and reasonably  entitled to
          indemnity for such expenses.

     Our  certificate  of  incorporation  provides  that  directors  will not be
personally  liable for monetary  damages to us or our stockholders for breach of
fiduciary  duty as a director,  except for liability  resulting from a breach of
the director's duty of loyalty to us or our stockholders, intentional



misconduct or willful  violation of law, actions or inactions not in good faith,
an unlawful  stock  purchase  or payment of a dividend  under  Delaware  law, or
transactions  from which the director derives improper  personal  benefit.  Such
limitation of liability does not affect the  availability of equitable  remedies
such as injunctive relief or rescission.  Our certificate of incorporation  also
authorizes us to indemnify our officers,  directors and other agents, by bylaws,
agreements or otherwise,  to the fullest extent permitted under Delaware law. We
have entered into an  indemnification  agreement  with each of our directors and
officers which may, in some cases, be broader than the specific  indemnification
provisions  contained  in  our  certificate  of  incorporation  or as  otherwise
permitted  under  Delaware law. Each  indemnification  agreement may require us,
among other things,  to indemnify  such officers and directors  against  certain
liabilities that may arise by reason of their status or service as a director or
officer,  against  liabilities  arising  from willful  misconduct  of a culpable
nature, and to obtain directors' and officers'  liability insurance if available
on reasonable terms.

     We maintain directors and officers liability policies with SPMI (Lloyd's of
London) and North American Specialty (Swiss Reinsurance) that contain a combined
limit of liability of $5,000,000 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-2


               (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 Securities and Exchange  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  will be  deemed to be a new
registration  statement  relating to the  securities  offered  therein,  and the
offering of such  securities  at that time will 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 may be permitted to directors,  officers and controlling  persons of the
registrant pursuant to the foregoing  provisions,  or otherwise,  the registrant
has been advised that in the opinion of the Securities  and Exchange  Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable.

     In the event  that a claim for  indemnification  against  such  liabilities
(other than the  payment by the  registrant  of  expenses  incurred or paid by a
director,  officer or  controlling  person of the  registrant in the  successful
defense of any action, suit or proceeding) is asserted by such director, officer
or controlling  person in connection with the securities being  registered,  the
registrant  will,  unless in the  opinion  of its  counsel  the  matter 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   registrant  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  will  be  deemed  to  be a new  registration  statement
relating to the securities offered therein,  and the offering of such securities
at that time will be deemed to be the initial bona fide offering thereof.

                                      II-3


                                   SIGNATURES

     Pursuant to the  requirements of the Securities Act of 1933, the registrant
certifies  that it has  reasonable  grounds to believe  that it meets all of the
requirements  for  filing  on Form S-3 and has  duly  caused  this  registration
statement  to be  signed  on its  behalf  by  the  undersigned,  thereunto  duly
authorized, in the City of Fairfax, Commonwealth of Virginia on August 31, 2001.
