                                  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
by reference in the section "Where You Can Find More Information About Us,"
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:                            $ 5,298,633
                      o  December 31, 1996                       $10,051,757
                      o  December 31, 1997                       $13,001,338
                      o  December 31, 1998                       $16,697,413
                      o  December 31, 1999                       $24,185,222
                      o  December 31, 2000

                  Fiscal quarters ended:
                      o  March 31, 2001                          $ 5,936,589
                      o  June 30, 2001                           $ 8,453,995
                      o  September 30, 2001                      $ 8,073,236

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 initiated shipments of this product and the MA(R) TC late in our third
fiscal quarter. 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 have significant commitments to purchase inventory and services in the
future.

          We have commitments to purchase inventory, tooling and engineering and
other services from our suppliers and manufacturers related to the design,
manufacture and procurement of our hardware product lines. We are obligated to
purchase certain components of the MA V system from IBM, including approximately
24,000 computing units (the "MA V CPUs"). The MA V CPUs are scheduled for
purchase over an 18 month period following final acceptance by us, which
acceptance is determined by a number of criteria including receipt of
comprehensive product documentation and other customary deliverables. All
criteria for acceptance have not been met, but we expect that all criteria will
be met in the fourth fiscal quarter of 2001. Subsequent to acceptance, we may
cancel our purchase commitments by paying a cancellation fee in an amount not to
exceed approximately $4,000,000, which amount decreases in proportion to the
number of MA V CPUs purchased over the contract period. In addition to the
obligation related to the MA V CPUs, we have commitments to purchase computing
units, flat panel and head mounted displays, miscellaneous computing components
as well as engineering and other services from our various vendors related to
the MA V, MA TC, poma(TM) and future product lines. While the timing and amount
of many of these shipments and services may be adjusted through the payment of
cancellation fees or through contract negotiations, the total amount scheduled
to be paid for such items by us during the fourth fiscal quarter of 2001 and
fiscal year 2002 is estimated at between $45,000,000 and $50,000,000.

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


                                      -3-


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 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.

If our sales and receivables continue to be concentrated among a small number of
our customers, the loss of a customer, a substantial decrease of sales to one of
our customers or a customer's inability to pay amounts owed to us may have a
material adverse effect on our sales, operating results and cash flows

          A significant percentage of our sales has been concentrated among a
relatively small number of customers. For the nine months ended September 30,
2001, we had three (3) customers which each comprised more than 10% of our total
revenues, representing an aggregate of 39% of total revenues. Additionally, at
September 30, 2001, we had two (2) customers which comprised more than 10% of
our accounts receivable, representing an aggregate of 56% of total accounts
receivable. There can be no assurance that this concentration of sales and
receivables among customers will not continue in the future. The loss of a
significant customer or a substantial decrease in sales to such a customer would
have a material adverse effect on our sales and operating results. Our
arrangements with certain of our customers, especially those related to the sale
of our wearable computer hardware products, are based on the receipt of purchase
orders and otherwise are not subject to long-term written contracts and
generally may be terminated upon short notice. In addition, these and other


                                      -4-


customers may demand price concessions from us that could adversely affect
profit margins. Also, our cash flows may be adversely affected if a customer is
unable or unwilling to repay amounts owed to us.

                              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 November 26, 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.


                                      -5-


Our executive officers, directors and principal stockholders, together, may
exercise control over all matters submitted to a vote of stockholders.

          As of October 31, 2001, our executive officers, directors and
principal stockholders beneficially owned, in the aggregate, approximately 10.5%
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 13,130,642 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 November 28, 2001, we had 13,130,642 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

"believe," or other similar words. Similarly, statements that describe our
future plans, objectives and goals are also forward-looking statements. Our
factual results, performance or achievements could differ materially from those
expressed or implied in these forward-looking


                                      -6-


statements as a result of certain factors, including those listed in "Risk

                                 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 November 28, 2001 we had issued and outstanding 59,524,754
shares of common stock. At that date, there were an additional 13,130,642 shares
of common stock reserved for possible future issuances as follows:

          o    options to purchase 5,955,354 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 5,542,814 shares at a price between $2.00
               and $18.00 per share. Of the 5,542,814 shares, we have previously
               registered a total of 3,753,255 shares issuable upon exercise of
               these warrants. This prospectus covers an additional 1,422,059
               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    1,632,474 shares issuable upon exercise of options under the
               Company's stock incentive plans which have not been granted as of
               November 26, 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


                                      -8-


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.

          Holly Investments Limited acquired its shares of common stock in a
private placement transaction entered into on November 15, 2001. Under the terms
of the common stock and warrant purchase agreement between Holly Investments
Limited and us, we agreed to sell 2,352,941 shares of our common stock at a
price of $1.70 per share, representing an approximate 16% discount to the
closing bid price of the shares on the 15 trading days preceding the
finalization of negotiations, for gross proceeds of $4,000,000. We also issued
warrants to purchase shares of our common stock at


                                      -11-


$2.55 per share. 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 $3.25 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 as promptly as practicable after
filing but no later than ninety days after the closing date.

          Cranshire Capital L.P. and Euram Cap Strat. "A" Fund Limited each
acquired its shares of common stock in a private placement transaction entered
into on November 15, 2001. Under the terms of the common stock and warrant
purchase agreement with us, we agreed to sell an aggregate of 1,764,705 shares
of our common stock at a price of $1.70 per share, representing an approximate
16% discount to the closing bid price of the shares on the 15 trading days
preceding the finalization of negotiations, for gross proceeds of $3,000,000. We
also issued warrants to purchase shares of our common stock at $2.55 per share.
The warrants are exercisable for a period of 4 years from the date of issuance.
We may call up to 100% of the warrants if the volume weighted average price of
our common stock (using the Bloomberg VWAP function) is equal to or greater than
$3.25 per share for ten 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 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, within 60 days after the closing
date and have such registration statement declared effective as promptly as
practicable after filing but no later than 120 days after the closing date. If
the registration statement is not declared effective within such 120-day period,
we agreed to pay to each of the holders liquidated damages in an amount equal to
2% of the purchase price paid by that holder for the shares of common stock
purchased pursuant to the common stock and warrant purchase agreement for each
30-day period after the end of such 120-day period until the registration
statement is declared effective. Payment of the liquidated damages will be
either in cash or in shares of common stock at the option of the holder. Under
the registration rights agreement, the shares of common stock cannot be sold or
otherwise transferred for a period of 100 days from the closing date.

          Cleveland Overseas Ltd., ZLP Master Technology Fund, Ltd. and Vertical

either in cash or in shares of common stock at the option of the holder. Under
the registration rights agreement, the shares of common stock cannot be sold or
otherwise transferred for a period of 100 days from the closing date.

          On November 15, 2001, we entered into an agreement with Atlas Capital
Services, LLC whereby we agreed to pay cash in the amount of $157,500 and
warrants to purchase 61,765 shares of our common stock at $2.55 per share as a
fee for certain financial advisory services rendered to us in connection with
the private placement transaction. The warrants are exercisable for a period of
4 years from the date of issuance. We may call up to 100% of the warrants if the
volume weighted average price of our common stock (using the Bloomberg VWAP
function) is equal to or greater than $3.25 per share for ten consecutive
trading days.

          frog werk, Inc. provides certain product development, marketing and
other services to our company. The shares of common stock were issued to frog
werk, Inc. as partial compensation for services rendered to us for the period
ending November 27, 2001. The shares of common stock were issued at $1.93 per
share, representing a 15% discount to the closing market price of our common
stock on November 26, 2001, the day preceding the date of the agreement. The
agreement provides that we will file a registration statement for the shares of
common stock underlying such warrants within 90 days and use our reasonable best
efforts to cause such registration statement to be declared effective.

         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 have 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 November 28, 2001, we have 59,524,754 shares of
common stock issued and outstanding. We have reserved 13,130,642 shares of
common stock for issuance upon exercise of options and warrants.


                                      -13-


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 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


                                      -14-


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:

          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


                                      -15-


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.

                              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.


                                      -16-


          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;
          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) 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.


                                      II-3


          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.

                                   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 November 28,
2001.
