                   COMMON STOCK AND WARRANT PURCHASE AGREEMENT


     This COMMON STOCK AND WARRANT PURCHASE  AGREEMENT dated as of June 30, 2002
(this "Agreement"), by and between XYBERNAUT CORPORATION, a Delaware corporation
(the  "Company"),  and the Purchaser whose name is set forth on Exhibit A hereto
(the "Purchaser").

                                    RECITALS

     WHEREAS, upon the terms and subject to the conditions contained herein, the
Company desires to issue and sell to the Purchaser, and the Purchaser desires to
purchase  from the Company in the  aggregate  3,333,333  shares of the Company's
common  stock,  par value $.01 per share (the "Common  Stock"),  and warrants to
purchase up to in the aggregate  833,333 shares of Common Stock purchased by the
Purchaser,  the  Warrants  to be in the form  attached  hereto as Exhibit B (the
"Warrants").

     WHEREAS,  such  investments will be made in reliance upon the provisions of
Section  4(2) of the  Securities  Act of 1933,  as  amended,  and the  rules and
regulations  promulgated thereunder (the "Securities Act"), including Regulation
D  ("Regulation  D"),  and/or upon such other  exemption  from the  registration
requirements  of the  Securities  Act as may be available with respect to any or
all of the investments to be made hereunder.

     NOW, THEREFORE, the parties hereto agree as follows:


                                   ARTICLE I

                PURCHASE AND SALE OF THE SHARES AND THE WARRANTS

     Section 1.1 Purchase and Sale of the Shares.  Upon the following  terms and
subject to the conditions  contained herein, the Company shall issue and sell to
the Purchaser and the Purchaser  shall purchase from the Company an aggregate of
3,333,333  shares of Common Stock as set forth with respect to the  Purchaser on
Exhibit A hereto  (collectively,  the  "Shares").  Upon the following  terms and
subject  to the  conditions  contained  herein,  the  Purchaser  shall be issued
Warrants.  The purchase  price per share of Common Stock shall be equal to $0.60

exercise of the Warrants.  Any shares of Common Stock  issuable upon exercise of
the  Warrants  (and such  shares  when  issued)  are herein  referred  to as the
"Warrant Shares".  The Shares, the Warrants and the Warrant Shares are sometimes
collectively referred to herein as the "Securities".






     Section 1.3 Purchase Price and Closing.  In consideration of and in express
reliance upon the representations,  warranties,  covenants, terms and conditions
of this Agreement, the Company agrees to issue and sell to the Purchaser and the
Purchaser  agrees to purchase that number of Shares set forth  opposite its name
on Exhibit A, which  purchase price for the Purchaser is set forth on Exhibit A.
The closing  under this  Agreement  shall take place at the offices of Jenkens &

which the last to be fulfilled or waived of the  conditions set forth in Article
IV  hereof  and  applicable  to the  Closing  shall be  fulfilled  or  waived in
accordance  herewith  or (ii) such  other  time and place or on such date as the
Purchaser and the Company may agree upon (the "Closing  Date").  At the Closing,
the Company shall receive gross proceeds from the Purchaser and other  investors
in an aggregate amount of not less than $4,000,000.

     Section 1.4  Warrants.  Concurrently  with the issuance of the Shares,  the
Company  shall issue to the  Purchaser  Warrants to  purchase  an  aggregate  of
833,333  shares of Common Stock,  as set forth on Exhibit A. The Warrants  shall

                                   ARTICLE II

                         REPRESENTATIONS AND WARRANTIES

     Section 2.1  Representation  and  Warranties  of the  Company.  The Company
hereby makes the following  representations  and  warranties  to the  Purchaser,
except as set forth in the Company's  disclosure  schedules  delivered with this
Agreement:

          (a)   Organization,   Good  Standing  and  Power.  The  Company  is  a
corporation duly  incorporated,  validly existing and in good standing under the
laws of the State of  Delaware  and has the  requisite  corporate  power to own,
lease and operate its properties and assets and to conduct its business as it is
now  being  conducted  and to enter  into  this  Agreement  and to  perform  its
obligations  hereunder.  The Company does not have any  subsidiaries (as defined
hereinafter)  or own  securities of any kind in any other entity,  except as set
forth in the  Company's  Annual  Report on Form 10-K for the  fiscal  year ended
December 31, 2001 (the "Form 10-K"), the Company's Quarterly Report on Form 10-Q
for the fiscal  period  ended March 31,  2002,  and all of the  Company's  other
filings with the  Securities  and Exchange  Commission  (the "SEC") prior to the
date hereof  (collectively,  the "Commission  Documents").  The Company and each
subsidiary is duly  qualified as a foreign  corporation to do business and is in
good  standing  in  every  jurisdiction  in which  the  nature  of the  business
conducted or property owned by it makes such qualification  necessary except for
any  jurisdiction(s)  (alone or in the  aggregate) in which the failure to be so
qualified will not have a Material  Adverse Effect (as defined  hereinafter)  on
the Company's financial condition.  For the purposes of this Agreement, the term
"Material  Adverse  Effect"  shall  mean  any  material  adverse  effect  on the
business,  operations,  properties,  prospects, assets or financial condition of
the  Company  and its  subsidiaries,  taken as a whole or



                                       2


which is likely to  materially  hinder  the  performance  by the  Company of its
obligation  hereunder and under the other  Transaction  Documents (as defined in
Section 2.1(b) hereof).

          (b)  Authorization;   Enforcement.   The  Company  has  the  requisite
corporate  power and authority to enter into and perform its  obligations  under
this Agreement,  the Registration  Rights Agreement attached as Exhibit C hereto
(the  "Registration  Rights  Agreement"),  the Transfer Agent  Instructions  (as
defined in Section 3.7 hereof) and the  Warrants  (sometimes  collectively,  the
"Transaction Documents") and to issue and sell the Shares in accordance with the
terms hereof and the Warrants.  The execution,  delivery and performance of each
of the Transaction  Documents by the Company and the consummation by the Company
of the transactions  contemplated  hereby and thereby have been duly and validly
authorized  by all  necessary  corporate  action,  and  no  further  consent  or
authorization  of the  Company  or  the  Company's  board  of  directors  or its
stockholders is required. This Agreement has been duly executed and delivered by
the Company.  The Registration Rights Agreement will have been duly executed and
delivered by the Company on or before the Closing Date.  Each of the Transaction
Documents constitutes,  or shall constitute when executed and delivered, a valid
and  binding  obligation  of the  Company  enforceable  against  the  Company in
accordance  with its  terms,  except as such  enforceability  may be  limited by
applicable  bankruptcy,  insolvency,  reorganization,  moratorium,  liquidation,
conservatorship,   receivership  or  similar  laws  relating  to,  or  affecting
generally  the  enforcement  of,  creditor's  rights  and  remedies  or by other
equitable principles of general application.

          (c)  Capitalization.  The authorized  capital stock of the Company and
the shares thereof issued and outstanding as of the date hereof are set forth on
Schedule 2.1(c) hereto.  All of the outstanding  shares of the Company's  Common
Stock  have  been  duly and  validly  authorized.  Except  as set  forth in this
Agreement  and  the  Registration  Rights  Agreement  and  as set  forth  in the
Commission  Documents or on Schedule 2.1(c) hereto, no shares of Common Stock or
any other securities issued by the Company are entitled to preemptive rights and
there are no outstanding options,  warrants, scrip, rights to subscribe to, call
or commitments of any character  whatsoever relating to, or securities or rights
convertible  into,  any shares of  capital  stock of the  Company.  Furthermore,
except as set forth in this Agreement and the Registration  Rights Agreement and
as set forth in the  Commission  Documents or on Schedule  2.1(c),  there are no
contracts, commitments,  understandings, or arrangements by which the Company is
or may  become  bound to issue  additional  shares of the  capital  stock of the
Company or  options,  securities  or rights  convertible  into shares of capital
stock of the Company.  Except for customary transfer  restrictions  contained in
agreements entered into by the Company in order to sell restricted securities or
as provided on the Commission  Documents or Schedule 2.1 (c) hereto, the Company
is  not a  party  to  or  bound  by  any  agreement  or  understanding  granting
anti-dilution  rights to any  person  with  respect to any of its equity or debt
securities.  The  Company  is not a party to,  and it has no  knowledge  of, any
agreement or  understanding  restricting the voting or transfer of any shares of
the  capital  stock  of the  Company.  Except  as set  forth  on the  Commission
Documents or Schedule  2.1(c)  hereto,  the offer and sale of all capital stock,
convertible securities, rights, warrants, or options of the Company issued prior
to the Closing  complied with all applicable  federal and state securities laws,
and no holder of such  securities has a right of rescission or claim for damages
with respect thereto which could have a Material Adverse Effect. The Company has
furnished or made  available  to the  Purchaser  true and correct



                                       3


copies  of the  Company's  Articles  of  Incorporation  as in effect on the date
hereof  (the  "Articles"),  and the  Company's  Bylaws  as in effect on the date
hereof (the "Bylaws").

          (d)  Issuance  of  Securities.  The Shares to be issued at the Closing
have been duly authorized by all necessary  corporate  action and, when paid for
or issued in  accordance  with the terms  hereof,  the  Shares  shall be validly
issued and outstanding,  fully paid and nonassessable,  and free from preemptive
rights, taxes upon issuance, liens and similar charges caused by the Company and
entitled to all  applicable  rights and  preferences  set forth in the Articles.
When the  Warrant  Shares  are  issued  in  accordance  with  the  terms of this
Agreement and as set forth in the Warrants,  such shares will be duly authorized
by all necessary corporate action and validly issued and outstanding, fully paid
and non-assessable,  and free from preemptive rights, taxes upon issuance, liens
and other  similar  charges  caused by the  Company,  and the  holders  shall be
entitled to all rights accorded to a holder of Common Stock.

          (e) No Conflicts.  Except as set forth in the Commission  Documents or
Schedule 2.1(e) attached hereto, the execution,  delivery and performance of the
Transaction  Documents by the Company and the consummation by the Company of the
transactions contemplated herein and therein do not and will not (i) violate any
provision of the Company's Articles or Bylaws, (ii) conflict with, or constitute
a default (or an event which with notice or lapse of time or both would become a
default)  under,  or  give to  others  any  rights  of  termination,  amendment,
acceleration  or  cancellation  of,  any  agreement,  mortgage,  deed of  trust,
indenture,  note, bond,  license,  lease agreement,  instrument or obligation to
which the  Company is a party or by which any of its  respective  properties  or
assets are bound,  (iii) create or impose a lien,  mortgage,  security interest,
charge or  encumbrance  of any nature  whatsoever on any property of the Company
under any  agreement  or any  commitment  to which the  Company is a party or by
which the  Company  is bound or by which  any of its  respective  properties  or
assets are bound, or (iv) result in a violation of any federal,  state, local or
foreign statute, rule, regulation,  order, judgment or decree (including federal
and state securities laws and  regulations)  applicable to the Company or any of
its  subsidiaries or by which any property or asset of the Company or any of its
subsidiaries are bound or affected,  except,  in all cases other than violations
pursuant  to clause  (i)  above,  for such  conflicts,  defaults,  terminations,
amendments,   acceleration,   cancellations   and   violations   as  would  not,
individually or in the aggregate,  have a Material Adverse Effect.  The business
of the Company and its  subsidiaries  is not being conducted in violation of any
laws,  ordinances or regulations of any governmental entity, except for possible
violations  which  singularly  or in the  aggregate  do not and  will not have a
Material  Adverse  Effect.  The Company is not required under federal,  state or
local law, rule or regulation to obtain any consent,  authorization or order of,
or make any filing or  registration  with, any court or  governmental  agency in
order for it to  execute,  deliver or perform any of its  obligations  under the
Transaction  Documents,  or issue and sell the Shares and the Warrant  Shares in
accordance with the terms hereof or thereof (other than any filings which may be
required  to be made by the  Company  with the  Commission  or state  securities
administrators subsequent to a Closing, and any registration statement which may
be filed pursuant  hereto);  provided  that, for purposes of the  representation
made in this sentence,  the Company is assuming and relying upon the accuracy of
the relevant representations and agreements of the Purchaser herein.



                                       4


          (f)  Commission  Documents,  Financial  Statements.  The  Company  has
provided to the  Purchaser  prior to the date hereof copies of the Form 10-K and
Form 10-Q for the fiscal  period  ended  March 31,  2002.  The  Company  has not
provided  to  the  Purchaser  any  material  non-public   information  or  other
information which, according to applicable law, rule or regulation,  should have
been  disclosed  publicly by the  Company  but which has not been so  disclosed,
other than with respect to the transactions  contemplated by this Agreement. The
financial statements of the Company furnished to the Purchaser comply as to form
in all  material  respects  with  applicable  accounting  requirements  and  the
published rules and regulations of the Commission or other  applicable rules and
regulations with respect thereto.  Such financial  statements have been prepared
in accordance with generally accepted accounting  principles ("GAAP") applied on
a consistent  basis during the periods  involved (except (i) as may be otherwise
indicated in such financial  statements or the notes thereto or (ii) in the case
of unaudited interim statements, to the extent they may not include footnotes or
may be  condensed  or summary  statements),  and fairly  present in all material
respects the financial  position of the Company and its  subsidiaries  as of the
dates thereof and the results of operations  and cash flows for the periods then
ended (subject,  in the case of unaudited  statements,  to normal year-end audit
adjustments).

          (g) Subsidiaries.  The Commission  Documents or Schedule 2.1(g) hereto
sets forth each  subsidiary  of the  Company  showing  the  jurisdiction  of its
incorporation  or  organization  and showing  the  percentage  of the  Company's
ownership of the outstanding  stock or other interests of such  subsidiary.  For
the purposes of this Agreement, "subsidiary" shall mean any corporation or other
entity  of  which at  least a  majority  of the  securities  or other  ownership
interest  having  ordinary  voting power  (absolutely or  contingently)  for the
election of directors or other persons  performing  similar functions are at the
time  owned  directly  or  indirectly  by the  Company  and/or  any of its other
subsidiaries.  All of the outstanding shares of capital stock of each subsidiary
have  been  duly  authorized  and  validly  issued,   and  are  fully  paid  and
non-assessable.  Except as disclosed on Schedule 2.1(g) there are no outstanding
preemptive,  conversion or other rights, options, warrants or agreements granted
or issued by or binding upon any  subsidiary  for the purchase or acquisition of
any  shares  of  capital  stock  of  any  subsidiary  or  any  other  securities
convertible into, exchangeable for or evidencing the rights to subscribe for any
shares of such capital stock.  Neither the Company nor any subsidiary is subject
to any obligation  (contingent or otherwise) to repurchase or otherwise  acquire
or retire any shares of the capital stock of any  subsidiary or any  convertible
securities,  rights,  warrants or options of the type described in the preceding
sentence.  Neither  the  Company  nor any  subsidiary  is party to,  nor has any
knowledge of, any agreement  restricting the voting or transfer of any shares of
the capital stock of any subsidiary.

          (h) No Material Adverse Change. Since March 31, 2002, the date through
which the most recent report of the Company has been prepared and filed with the
Commission (a copy of which is included in the Commission Documents) the Company
has not experienced or suffered any Material Adverse Effect, except as disclosed
on Schedule 2.1(h) hereto.

          (i) No Undisclosed Liabilities.  Except as disclosed in the Commission
Documents  or on  Schedule  2.1(i)  hereto,  neither  the Company nor any of its
subsidiaries  has  any  liabilities,  obligations,  claims  or  losses  (whether
liquidated or unliquidated,  secured or



                                       5


unsecured, absolute, accrued, contingent or otherwise) other than those incurred
in  the  ordinary  course  of  the  Company's  or  its  subsidiaries  respective
businesses  since  September  30,  2001,  and  which,  individually  or  in  the
aggregate, do not or would not have a Material Adverse Effect.

and  marketable  title  to all of its real and  personal  property,  free of any
mortgages,  pledges,  charges,  liens, security interests or other encumbrances,

not reasonably be expected to have a Material Adverse Effect.

          (n) Taxes. Except as set forth in the Commission Documents or Schedule

neither the Company, nor any of its affiliates,  nor any person acting on its or
their  behalf  has,  directly  or  indirectly,  made any  offers or sales of any
security or solicited any offers to buy any security,  under  circumstances that
would require  registration of any of the Securities under the 1933 Act or cause
this offering of the  Securities to be  integrated  with prior  offerings by the
Company for  purposes  of the 1933 Act or any  applicable  stockholder  approval
provisions,  including,  without limitation,  under the rules and regulations of
any exchange or automated quotation system on which any of the Securities of the
Company  are  listed  or  designated,  nor  will  the  Company  or  any  of  its
subsidiaries take any actions or steps that would require registration of any of
the Securities  under the 1933 Act or cause the offering of the Securities to be
integrated with other offerings.

          (y)  Eligibility.  The Company is  currently  eligible to register the
resale of the Securities on a registration  statement on Form S-3 under the 1933

     Section 2.2 Representations and Warranties of the Purchaser.  The Purchaser
hereby makes the following representations and warranties to the Company:

          (a)  Organization  and Standing of the  Purchaser.  The Purchaser is a
corporation,  limited  liability  company or partnership  duly  incorporated  or
organized,  validly  existing  and  in  good  standing  under  the  laws  of the
jurisdiction of its  incorporation  or  organization,  and the Purchaser was not
formed for the specific purpose of acquiring the Securities.

          (b) Authorization and Power. The Purchaser has the requisite power and
authority to enter into and perform this Agreement and the  Registration  Rights
Agreement  and to  purchase  the  Shares  and  the  Warrants  being  sold  to it
hereunder.  The  execution,  delivery and  performance of this Agreement and the
Registration  Rights  Agreement  and the  documents  contemplated  hereby by the
Purchaser and the consummation by them of the transactions  contemplated  hereby
and thereby have been duly authorized by all necessary  corporate  action and no
further  consent or  authorization  of the  Purchaser or its board of directors,
stockholders,  members,  managers or partners,  as the case may be, is required.
Each of this Agreement and the Registration Rights Agreement will have been duly
executed  and  delivered  by the  Purchaser  on the Closing  Date.  Each of this
Agreement and the Registration Rights Agreement constitutes, or shall constitute
when  executed and  delivered,  a valid and binding  obligation of the Purchaser



                                       9


enforceable  against the Purchaser in accordance with its terms,  except as such
enforceability   may  be   limited   by   applicable   bankruptcy,   insolvency,
reorganization,  moratorium,  liquidation,  conservatorship,   receivership,  or
similar laws relating to, or affecting  generally the enforcement of, creditor's
rights and remedies or by other equitable principles of general application.

          (c) No Conflicts.  The  execution,  delivery and  performance  of this
Agreement and the Registration  Rights Agreement and the documents  contemplated
hereby and thereby and the  consummation  by the  Purchaser of the  transactions
contemplated hereby or thereby or relating hereto or thereto do not and will not
(i)  result  in a  violation  of the  Purchaser's  charter  documents,  by-laws,
partnership agreement, operating agreement or other organizational documents, or
(ii) conflict with, constitute a default (or an event which with notice or lapse
of time or both would become a default)  under,  or give to others any rights of
termination, amendment, acceleration or cancellation of any agreement, indenture
or instrument to which the Purchaser is a party, or result in a violation of any
law,  rule,  or  regulation,  or any order,  judgment  or decree of any court or
governmental  agency  applicable to the Purchaser or its properties,  except for
such  conflicts,  defaults and violations as would not,  individually  or in the
aggregate,  prohibit or otherwise interfere with the ability of the Purchaser to
enter into and perform its  obligations  under this  Agreement  in any  material
respect.  The Purchaser is not required to obtain any consent,  authorization or
order of, or make any filing or  registration  with,  any court or  governmental
agency in order for it to  execute,  deliver or perform  any of its  obligations
under  this  Agreement,  the  Registration  Rights  Agreement  or the  documents
contemplated  hereby and  thereby or to purchase  the Shares or the  Warrants in
accordance   with  the  terms   hereof;   provided  that  for  purposes  of  the
representation made in this sentence, the Purchaser is assuming and relying upon
the  accuracy of the  relevant  representations  and  agreements  of the Company
herein.

          (d) Acquisition for Investment. The Purchaser is purchasing the Shares
and the  Warrants and will be acquiring  the Warrant  Shares  solely for its own
account,  for  investment  only and not with a view  towards  the public sale or
distribution  thereof.  The  Purchaser  agrees not to sell,  assign or otherwise
transfer  any of its  Securities  except in  accordance  with  federal and state
securities laws applicable to such disposition.  The Purchaser acknowledges that
it is able to bear the  financial  risks  associated  with an  investment in the
Securities and that it has been given full access to such records of the Company
and its  subsidiaries and to the officers of the Company and its subsidiaries as
it  has  deemed   necessary  or   appropriate   to  conduct  its  due  diligence
investigation. The Purchaser is capable of evaluating the risks and merits of an
investment in the  Securities by virtue of its experience as an investor and its
knowledge,  experience and  sophistication in financial and business matters and
the  Purchaser  is capable of bearing the entire loss of its  investment  in the
Securities.

          (e) Accredited Investor.  The Purchaser is an "accredited investor" as
defined in Regulation D promulgated under the Securities Act and is incorporated
in the state indicated on Exhibit A hereto.

          (f) Rule 144. The Purchaser  understands  that the Securities  must be
held indefinitely unless such Securities are registered under the Securities Act
or an exemption from registration is available.  The Purchaser acknowledges that
the Purchaser is familiar with Rule



                                       10


144 of the rules and  regulations  promulgated  pursuant to the  Securities  Act
("Rule  144"),  and that the  Purchaser  has been  advised that Rule 144 permits
resales only under certain circumstances.  The Purchaser understands that to the
extent that Rule 144 is not available,  it will be unable to sell any Securities
without either registration under the Securities Act or the existence of another
exemption from such registration requirement.

          (g)  Information.  The Purchaser  and its advisors,  if any, have been
furnished with all materials  relating to the business,  finances and operations
of the Company and  materials  relating to the offer and sale of the  Securities
which have been requested by the Purchaser.  The Purchaser and its advisors,  if
any, have been afforded the  opportunity to ask questions of and receive answers
from, or obtain  additional  information  from,  the  executive  officers of the
Company the financial and other affairs of the Company. The Purchaser has sought
such accounting,  legal and tax advice as it has considered necessary to make an
informed  investment decision with respect to its acquisition of the Securities.
The Purchaser understands that it (and not the Company) shall be responsible for
its own tax  liabilities  that may arise as a result of this  investment  or the
transactions contemplated by this Agreement.  Without limiting the generality of
the  foregoing,  the  Purchaser  has also had the  opportunity  to obtain and to
review the Commission Documents.

          (h) No Solicitation.  The Purchaser  acknowledges  that the Shares and
the Warrants  were not offered to the  Purchaser by means of any form of general
or  public  solicitation  or  general  advertising,   or  publicly  disseminated
advertisements or sales literature,  including (i) any advertisement,  articles,
notice or other communication  published in any newspaper,  magazine, or similar
media,  or broadcast over television or radio, or (ii) any seminar or meeting to
which the Purchaser was invited by any of the foregoing means of communications.

          (i) No Endorsement.  The Purchaser  understands  that no United States
federal  or  state  agency  or  any  other  government  or  governmental  agency
(including,   without   limitation,   the  SEC)  has   passed  on  or  made  any
recommendation or endorsement of the Securities.

          (j)  General.  The  Purchaser  understands  that  the  Shares  and the
Warrants are being offered and sold,  and the Warrant  Shares are being offered,
to the  Purchaser  in  reliance  on specific  exemptions  from the  registration
requirement of federal and state securities laws and that the Company is relying
upon the truth and accuracy of, and the compliance  with,  the  representations,
warranties,  agreements,  acknowledgments and understanding of the Purchaser set
forth herein in order to determine the  applicability of such exemptions and the
eligibility  of the  Purchaser  to acquire  the Shares and the  Warrants  and to
receive an offer of the Warrant Shares.

          (k) No Commissions or Similar Fees. In connection with the purchase of
the Shares and Warrants by the Purchaser, the Purchaser has not and will not pay
any commission or other direct or indirect  remuneration to any person or entity
for soliciting or otherwise coordinating the purchase of such securities, except
as set forth on Schedule  2.2(k) hereto.  All such persons or entities listed on
Schedule  2.2(k)  hereto  are duly  licensed  and/or  registered  to  engage  in
securities  offering and selling  activities  (or are exempt from such licensing
and/or



                                       11


registration  requirements)  under  applicable  federal laws and the laws of the
state(s)  in which such  activities  have  taken  place in  connection  with the
transaction contemplated by this Agreement.


                                  ARTICLE III

                                    COVENANTS

     The Company covenants with the Purchaser,  for so long as the Shares and/or
the Warrants remain outstanding, as follows (which covenants are for the benefit
of the Purchaser and its permitted assignees):

     Section 3.1 Securities Compliance.

          (a) The Company shall notify the  Commission in accordance  with their
rules and regulations of the transactions contemplated by any of the Transaction
Documents,  as may be required,  and shall take all other  necessary  action and
proceedings  as may be  required  and  permitted  by  applicable  law,  rule and
regulation,  for the legal and valid  issuance  of the  Shares  and the  Warrant
Shares to the Purchaser or  subsequent  holders and will take no action to cause
integration under the 1933 Securities Act or the rules of Nasdaq.

          (b) The  Company  is  relying  upon  the  truth  and  accuracy  of the
representations,  warranties, agreements,  acknowledgments and understandings of
the  Purchaser  set forth  herein in order to  determine  the  applicability  of
federal  and  state  securities  laws  exemptions  and  the  suitability  of the
Purchaser to acquire the Shares and the Warrants.

     Section 3.2 Compliance with Laws. The Company shall comply,  and cause each
subsidiary to comply,  with all applicable laws, rules,  regulations and orders,
noncompliance with which could have a Material Adverse Effect.

     Section 3.3 Keeping of Records and Books of Account. The Company shall keep
and cause each  subsidiary  to keep  adequate  records and books of account,  in
which entries will be made in accordance with United States  generally  accepted
accounting principles  consistently  applied,  reflecting all material financial
transactions of the Company and its subsidiaries,  and in which, for each fiscal
year,   all  proper   reserves  for   depreciation,   depletion,   obsolescence,
amortization,  taxes,  bad debts  and  other  purposes  in  connection  with its
business shall be made.

     Section 3.4 Amendments.  The Company shall not amend or waive any provision
of the Articles or Bylaws of the Company,  or the Registration  Rights Agreement
in any way that would adversely  affect the dividend  rights,  exercise  rights,
voting rights or redemption rights of the holders of the Shares, the Warrants or
the Warrant Shares.

     Section  3.5  Other  Agreements.  The  Company  shall  not  enter  into any
agreement  in which the terms of such  agreement  would  restrict  or impair the
right  or  ability  to  perform  of the  Company  or any  subsidiary  under  any
Transaction Document. In addition,  unless and until the



                                       12


registration statement to be filed in connection with the purchase of the Shares
and Warrants by the  Purchaser  hereunder is declared  effective by the SEC, the
Company  shall not enter into an  agreement  to sell  securities  with any other
investor at a purchase price per share less than $0.75 per share.

     Section 3.6  Reservation of Shares.  So long as any of the Warrants  remain
outstanding,  the Company  shall take all action  necessary to at all times have
authorized,  and reserved for the purpose of issuance,  no less than 100% of the
aggregate number of shares of Common Stock needed to provide for the issuance of
the Warrant Shares.

     Section  3.7  Transfer   Agent   Instructions.   The  Company  shall  issue
irrevocable  instructions  to its transfer  agent,  and any subsequent  transfer
agent,  to issue  certificates,  registered  in the name of the Purchaser or its
respective nominee(s),  for the Shares and the Warrant Shares in such amounts as
specified from time to time by the Purchaser to the Company upon issuance of the
Shares or exercise of the Warrants in the form of Exhibit C attached hereto (the
"Irrevocable Transfer Agent Instructions").  Prior to registration of the Shares
and the Warrant Shares under the  Securities  Act, all such  certificates  shall
bear the  restrictive  legend  specified in Section 5.1 of this  Agreement.  The
Company warrants that no instruction  other than the Irrevocable  Transfer Agent
Instructions referred to in this Section 3.7 will be given by the Company to its
transfer  agent with  respect to the Shares and the Warrant  Shares and that the
Shares and the Warrant  Shares  shall  otherwise be freely  transferable  on the
books and records of the Company as and to the extent provided in this Agreement
and the Registration Rights Agreement.  Nothing in this Section 3.7 shall affect
in any way the  Purchaser's  obligations and agreements set forth in Section 5.1
to comply with all applicable  prospectus  delivery  requirements,  if any, upon
resale of the  Shares or the  Warrant  Shares.  If the  Purchaser  provides  the
Company with an opinion of counsel (such counsel to be reasonably  acceptable to
the Company),  in a generally acceptable form, to the effect that a public sale,
assignment  or  transfer  of the  Shares or Warrant  Shares may be made  without
registration  under the Securities  Act or such  Purchaser  provides the Company
with  reasonable  assurances  that the Shares or the Warrant  Shares can be sold
pursuant  to Rule 144  without any  restriction  as to the number of  securities
acquired as of a particular date that can then be immediately  sold, the Company
shall  permit the  transfer,  and,  in the case of the  Shares  and the  Warrant
Shares,  promptly  instruct  its  transfer  agent  to  issue  one  (1)  or  more
certificates  in  such  name  and in such  denominations  as  specified  by such
Purchaser and without any restrictive  legend.  The Company  acknowledges that a
breach by it of its  obligations  under this Section 3.7 will cause  irreparable
harm to the  Purchaser  by vitiating  the intent and purpose of the  transaction
contemplated  hereby.  Accordingly,  the Company acknowledges that the remedy at
law for a breach of its  obligations  under this Section 3.7 will be  inadequate
and agrees,  in the event of a breach or threatened breach by the Company of the
provisions  of this  Section  3.7,  that the  Purchaser  shall be  entitled,  in
addition  to  all  other  available  remedies,  to an  order  and/or  injunction
restraining any breach and requiring  immediate  issuance and transfer,  without
the necessity of showing  economic  loss and without any bond or other  security
being required.

the  representations  and warranties of the Company shall be true and correct in
all  material  respects as of the date when made and as of the Closing as though

escalation of hostilities or other national or international  calamity or crisis

decree,  ruling or injunction shall have been enacted,  entered,  promulgated or

purpose  of  effecting  the  issuance  of the  Shares  and the  exercise  of the

shares of Common Stock which would be issuable  upon  issuance of the Shares and
upon exercise of the Warrants  following the Closing (after giving effect to the
Shares and  Warrants  to be issued on the  Closing  Date and  assuming  all such
Shares and Warrants were fully issuable and exercisable,  as applicable, on such

                                   ARTICLE V

                            STOCK CERTIFICATE LEGEND

     Section 5.1 Legend. Each certificate representing the Shares, the Warrants,
and the securities issued upon exercise thereof,  as applicable and appropriate,
shall be stamped  or  otherwise  imprinted  with a legend in  substantially  the
following  form (in  addition  to any legend  required  by  applicable  federal,
provincial or state securities or "blue sky" laws):

     THE SECURITIES  REPRESENTED BY THIS CERTIFICATE (THE "SECURITIES") HAVE
     NOT BEEN  REGISTERED  UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
     "SECURITIES  ACT")  OR  STATE  SECURITIES  LAWS  AND MAY  NOT BE  SOLD,
     TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED OR OTHERWISE DISPOSED OF
     UNLESS  REGISTERED  UNDER THE SECURITIES ACT AND UNDER APPLICABLE STATE
     SECURITIES LAWS OR XYBERNAUT  CORPORATION  (THE  "COMPANY")  SHALL HAVE
     RECEIVED AN OPINION IN FORM, SCOPE AND SUBSTANCE REASONABLY  ACCEPTABLE
     TO THE COMPANY, OF COUNSEL, WHO IS REASONABLY ACCEPTABLE TO THE COMPANY
     THAT REGISTRATION OF SUCH SECURITIES UNDER THE SECURITIES ACT AND UNDER
     THE PROVISIONS OF APPLICABLE  FEDERAL AND STATE  SECURITIES LAWS IS NOT
     REQUIRED.

     The  Company  agrees  to  reissue  certificates  representing  the  Shares,
Warrants or Warrant Shares,  without the legend set forth above if at such time,
such holder  thereof  shall give written  notice to the Company  describing  the
manner and terms of such  transfer  and removal as the  Company  may  reasonably
request and such holder  otherwise  complies  with the terms of the  Transaction
Documents.  The legend set forth above  shall be removed  and the Company  shall
issue a certificate without such legend to the holder of any Shares, Warrants or
Warrant Shares upon which it is stamped if, unless otherwise required by federal
or state  securities  laws,  (a) the sale of such  Shares,  Warrants  or Warrant
Shares is registered under the Securities Act (including  registration  pursuant
to Rule 416 thereunder) as contemplated by the Registration Rights Agreement (b)
such holder provides the Company with an opinion of counsel, in form,  substance
and scope customary for opinions of counsel in comparable  transactions,  to the
effect that a sale or transfer of such Shares, Warrants or Warrant Shares may be
made without  registration under the Securities Act; or (c) such holder provides
the Company with  reasonable  assurances  that such Shares,  Warrants or Warrant
Shares can be sold under Rule  144(k).  The  Purchaser  agrees that it will only
sell  Shares,  Warrants or Warrant  Shares,  including  those  represented  by a
certificate(s) from which the legend has been removed,  pursuant to an effective
registration statement, under



                                       16


an exemption  from the  registration  requirements  of the  Securities Act or in
accordance  with Rule 144.  In the event the above  legend is  removed  from any
Shares,  Warrant  or  Warrant  Shares and the  effectiveness  of a  registration
statement  covering such Shares,  Warrants or Warrant Shares is suspended or the
Company  determines  that a  supplement  or  amendment  thereto is  required  by
applicable securities laws, then upon reasonable advance notice to the Purchaser
the  Company  may require  that the above  legend be placed on any such  Shares,
Warrants or Warrant  Shares that  cannot then be sold  pursuant to an  effective
registration statement, under an exemption from the registration requirements of
the Securities Act or under Rule 144(k) and the Purchaser shall cooperate in the
replacement  of such legend.  Such legend shall  thereafter be removed when such
Shares,  Warrants or Warrant  Shares may again be sold  pursuant to an effective
registration statement, under an exemption from the registration requirements of
the Securities Act or under Rule 144(k).  The restrictions on transfer contained
in Section 5.1 shall be in  addition  to, and not by way of  limitation  of, any
other restrictions on transfer contained in any other section of this Agreement.


                                   ARTICLE VI

                                 INDEMNIFICATION

     Section 6.1 General  Indemnity.  The Company  agrees to indemnify  and hold
harmless  the  Purchaser  (and  its  directors,  officers,  affiliates,  agents,
successors and assigns) from and against any and all actual losses, liabilities,
deficiencies,   costs,  damages  and  reasonable  expenses  (including,  without
limitation,  reasonable attorney's fees, charges and disbursements)  incurred by
the Purchaser as a result of any breach of any of the covenants, representations
and warranties made by the Company herein. The Purchaser agrees to indemnify and
hold  harmless  the Company and its  directors,  officers,  affiliates,  agents,
successors and assigns from and against any and all actual losses,  liabilities,
deficiencies,   costs,  damages  and  reasonable  expenses  (including,  without
limitation,  reasonable attorneys' fees, charges and disbursements)  incurred by
the Company as a result of any breach of any of the  covenants,  representations
or warranties made by such Purchaser herein; provided, however, such Purchaser's
indemnification obligations shall not exceed the Purchase Price.

     Section   6.2   Indemnification    Procedure.   Any   party   entitled   to
indemnification under this Article VI (an "indemnified party") will give written
notice  to the  indemnifying  party of any  matters  giving  rise to a claim for
indemnification;   provided,   that  the  failure  of  any  party   entitled  to
indemnification  hereunder  to give notice as provided  herein shall not relieve
the indemnifying  party of its obligations under this Article VII, except to the
extent that the  indemnifying  party is actually  materially  prejudiced by such
failure  to give  notice.  In case any  action,  proceeding  or claim is brought
against  an  indemnified  party in respect  of which  indemnification  is sought
hereunder, the indemnifying party shall be entitled to participate in, unless in
the reasonable  judgment of the indemnified party a conflict of interest between
it and the indemnifying  party may exist with respect of such action, an action,
a proceeding or a claim, to assume the defense  thereof with counsel  reasonably
satisfactory to the indemnified  party. In the event that the indemnifying party
advises  an   indemnified   party  that  it  will   contest  such  a  claim  for
indemnification  hereunder,  or fails, within thirty (30) days of receipt of any
indemnification



                                       17


notice to notify, in writing,  such person of its election to defend,  settle or
compromise,  at its sole cost and expense,  any action,  proceeding or claim (or
discontinues its defense at any time after it commences such defense),  then the
indemnified party may, at its option,  defend, settle or otherwise compromise or
pay such action or claim. In any event,  unless and until the indemnifying party
elects in writing to assume  and does so assume the  defense of any such  claim,
proceeding or action, the indemnified  party's costs and expenses arising out of
the defense,  settlement or  compromise of any such action,  claim or proceeding
shall be losses subject to  indemnification  hereunder.  The  indemnified  party
shall  cooperate  fully  with  the  indemnifying  party in  connection  with any
negotiation or defense of any such action or claim by the indemnifying party and
shall furnish to the indemnifying party all information  reasonably available to
the indemnified  party which relates to such action or claim.  The  indemnifying
party shall keep the  indemnified  party  fully  apprised at all times as to the
status of the defense or any settlement  negotiations  with respect thereto.  If
the  indemnifying  party  elects to defend  any such  action or claim,  then the
indemnified  party shall be entitled to participate in such defense with counsel
of its choice at its sole cost and expense, unless in the reasonable judgment of
the  indemnified  party a conflict of interest  between it and the  indemnifying
party may exist with  respect to such action or claim.  The  indemnifying  party
shall  not be liable  for any  settlement  of any  action,  claim or  proceeding
effected  without its prior written  consent.  Notwithstanding  anything in this
Article VI to the  contrary,  the  indemnifying  party  shall not,  without  the
indemnified   party's  prior  written   consent  (which  consent  shall  not  be
unreasonable  withheld),  settle or compromise  any claim or consent to entry of
any  judgment in respect  thereof  which  imposes any future  obligation  on the
indemnified party or which does not include,  as an unconditional  term thereof,
the  giving by the  claimant  or the  plaintiff  to the  indemnified  party of a
release  from all  liability  in  respect  of such  claim.  The  indemnification
required  by this  Article VI shall be made by  periodic  payments of the amount
thereof  during the course of  investigation  or defense,  as and when bills are
received or expense,  loss,  damage or  liability  is  incurred,  so long as the
indemnified party  irrevocably  agrees to refund such moneys if it is ultimately
determined by a court of competent jurisdiction that such party was not entitled
to  indemnification.  The  indemnity  agreements  contained  herein  shall be in
addition to (a) any cause of action or similar rights of the  indemnified  party
against  the   indemnifying   party  or  others  and  (b)  any  liabilities  the
indemnifying party may be subject to pursuant to the law.


                                  ARTICLE VII

                                  MISCELLANEOUS

proceeding  arising  out of or relating  to this  Agreement  or any of the other
Transaction Documents or the transactions  contemplated



                                       18


hereunder or thereunder and (ii) hereby waives,  and agrees not to assert in any
such suit, action or proceeding,  any claim that it is not personally subject to
the jurisdiction of such court,  that the suit,  action or proceeding is brought
in an inconvenient  forum or that the venue of the suit, action or proceeding is
improper.  Each of the Company and Purchaser consents to process being served in
any such suit,  action or  proceeding by mailing a copy thereof to such party at
the  address in effect for  notices to it under this  Agreement  and agrees that
such service shall constitute good and sufficient  service of process and notice
thereof.  Nothing in this  Section 7.2 shall  affect or limit any right to serve
process in any other manner permitted by law.

attached hereto contain the entire  understanding of the parties with respect to
the matters  covered  hereby,  supersedes all prior  agreements  with respect to

Shares or in the  Warrants,  neither  the Company  nor the  Purchaser  makes any
representations, warranty, covenant or undertaking with respect to such matters.

instrument signed by the party against whom enforcement of any such amendment or
waiver is sought.
