                   COMMON STOCK AND WARRANT PURCHASE AGREEMENT


         This COMMON STOCK AND WARRANT PURCHASE AGREEMENT dated as of November
15, 2001 (this "Agreement"), by and between XYBERNAUT CORPORATION, INC., a
Delaware corporation (the "Company"), and each of the Purchasers whose names are
set forth on Exhibit A hereto (individually, a "Purchasers" and collectively,
the "Purchasers").

                                    RECITALS

         WHEREAS, upon the terms and subject to the conditions contained herein,
the Company desires to issue and sell to the Purchasers, and the Purchasers
desire to purchase from the Company in the aggregate 1,323,529 shares of the
Company's common stock, par value $.01 per share (the "Common Stock"), and
warrants to purchase up to in the aggregate 330,883 shares of Common Stock
purchased by the Purchasers, 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  Purchasers  and the  Purchasers  shall  purchase  from  the  Company  an
aggregate of 1,323,529  shares of Common Stock as set forth with respect to each
Purchaser on Exhibit A hereto (collectively,  the "Shares").  Upon the following
terms and subject to the conditions  contained  herein,  the Purchasers shall be
issued Warrants.  The purchase price per share of Common Stock shall be equal to
the  average  of the  closing  bid  price of the  Common  Stock for the prior 15
trading  days,  reduced by a 16%  discount to such average  price,  or $1.70 per
share.

         Section 1.2 The Securities. The Company has authorized and has reserved
and  covenants  to  continue  to reserve,  free of  preemptive  rights and other
similar  contractual  rights  of  stockholders,   a  sufficient  number  of  its
authorized but unissued shares of its Common Stock to effect the issuance of the
Shares and 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
Purchasers and the Purchasers, severally but not jointly, agree to purchase that
number of Shares set forth opposite their  respective  names on Exhibit A for an
aggregate purchase price of $2,250,000,  which purchase price for each Purchaser
is set forth on Exhibit A. The closing under this Agreement  shall take place at
the offices of Jenkens & Gilchrist Parker Chapin LLP, The Chrysler Building, 405
Lexington Avenue,  New York, New York 10174 (the "Closing") at 10:00 a.m. E.S.T.
on (i) the date on 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 Purchasers and the Company may agree upon (the "Closing Date").

         Section 1.4 Warrant.  Concurrently with the issuance of the Shares, the
Company  shall issue to the  Purchasers  Warrants to  purchase an  aggregate  of
441,176  shares of Common Stock,  as set forth on Exhibit A. The Warrants  shall
have an exercise  price equal to the Exercise  Price (as defined in the Warrant)
and shall expire on the fourth (4th)  anniversary  of the issuance  date of such
Warrants.


                                   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  Purchasers,
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  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,  2000 (the
"Form 10-K"), the Company's Quarterly Reports on Form 10-Q for the fiscal period
ended March 31,  2001,  June 30, 2001 and  September  30,  2001,  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,  "Material  Adverse Effect" means any adverse effect on the business,
operations,  properties, prospects, assets or financial condition of the Company
or its  subsidiaries  and which is  material  to such  entity or other  entities
controlling or controlled by such entity or which is likely to


                                       2


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 (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  Purchasers  true and


                                       3


correct 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 Purchasers herein.


                                       4


               (f) Commission Documents,  Financial Statements.  The Company has
provided to the Purchasers  prior to the date hereof copies of the Form 10-K and
Forms  10-Q for the fiscal  periods  ended  March 31,  2001,  June 30,  2001 and
September 30, 2001, respectively. The Company has not provided to the Purchasers
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 Purchasers  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

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

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

the capital stock of any subsidiary.

               (h) No Material  Adverse  Change.  Since  September 30, 2001, 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.

               (j)  No  Undisclosed   Events  or  Circumstances.   No  event  or
circumstance  has  occurred  or  exists  with  respect  to  the  Company  or its
subsidiaries or their respective businesses,  properties,  prospects, operations

requires public disclosure or announcement by the Company but which has not been
so publicly announced or disclosed.

               (k) Title to Assets. Each of the Company and its subsidiaries has
good and marketable title to all of its real and personal property,  free of any
mortgages,  pledges,  charges,  liens, security interests or other encumbrances,
except for those  indicated in the  Commission  Documents or on Schedule  2.1(k)

Adverse Effect on the Company's financial condition or operating results. Except
as described in the Commission  Documents or on Schedule 2.1(k) hereto, all said
leases of the Company and each of its  subsidiaries are valid and subsisting and
in full force and effect.

               (l)  Actions   Pending.   There  is  no  action,   suit,   claim,
investigation  or  proceeding  pending  or,  to the  knowledge  of the  Company,
threatened against the Company or any subsidiary which questions the validity of
this Agreement or the transactions contemplated hereby or any action taken or to
be taken pursuant hereto or thereto.  To the knowledge of the Company,  there is
no action,  suit,  claim,  investigation  or proceeding  pending or  threatened,
against or involving  the Company,  any  subsidiary  or any of their  respective
properties  or  assets,  except  as set  forth in the  Commission  Documents  or
Schedule 2.1(l) hereto. There are no outstanding orders, judgments, injunctions,
awards or decrees of any court,  arbitrator or  governmental  or regulatory body

applicable  federal,  state and local governmental laws, rules,  regulations and
ordinances,  except as set forth in the Commission  Documents or Schedule 2.1(m)
hereto  or  such  that,  individually  or in the  aggregate,  the  noncompliance
therewith would not have a Material Adverse Effect.  The Company and each of its
subsidiaries  have  all  franchises,   permits,  licenses,  consents  and  other
governmental  or  regulatory  authorizations  and  approvals  necessary  for the
conduct of its  business  as now being  conducted  by it unless  the  failure to
possess such franchises,  permits, licenses,  consents and other governmental or
regulatory authorizations and approvals, individually or in the aggregate, could
not reasonably be expected to have a Material Adverse Effect.

               (n) Taxes.  Except as set forth in the  Commission  Documents  or
Schedule 2.1(n) hereto,  the Company and each of the subsidiaries has accurately
prepared and filed all federal,  state and other tax returns  required by law to

                                       6


subject and which are not  currently  due and  payable.  Except as  disclosed on
Schedule 2.1(n) hereto, none of the federal income tax returns of the Company or
any subsidiary have been audited by the Internal  Revenue  Service.  The Company
has no knowledge of any  additional  assessments,  adjustments or contingent tax
liability (whether federal or state) of any nature  whatsoever,  whether pending

basis for any such assessment, adjustment or contingency.

               (o) Certain  Fees.  The Company  has not  employed  any broker or

               (p)   Operation  of  Business.   The  Company  and  each  of  the
subsidiaries owns or possesses all patents, trademarks, domain names (whether or
not registered)  and any patentable  improvements  or  copyrightable  derivative
works thereof,  websites and  intellectual  property  rights  relating  thereto,
service marks,  trade names,  copyrights,  licenses and  authorizations  and all
rights with respect to the foregoing, which are necessary for the conduct of its
business as now conducted  without any conflict with the rights of others except
as disclosed in the Commission Documents or on Schedule 2.1(p).

               (q) Material  Agreements.  Except as set forth in the  Commission
Documents  or on Schedule  2.1(q)  hereto,  or as  previously  disclosed  by the
Company to Purchasers,  neither the Company nor any subsidiary is a party to any
written or oral contract, instrument, agreement, commitment, obligation, plan or
arrangement,  a copy of which would be required to be filed with the  Commission
as an  exhibit  to a  registration  statement  on Form  S-3 or  applicable  form
(collectively,  "Material  Agreements")  if the Company or any  subsidiary  were
registering  securities  under the  Securities  Act.  Except as set forth in the
Commission  Documents or on Schedule 2.1(q) hereto,  the Company and each of its
subsidiaries has in all material respects performed all the obligations required
to be performed by them to date under the foregoing agreements, have received no
notice of default and, to the best of the Company's knowledge are not in default

Material  Adverse Effect.  No written or oral contract,  instrument,  agreement,
commitment,  obligation, plan or arrangement of the Company or of any subsidiary

laws. Assuming the representations set forth in Section 2.2 hereof are true, the
Securities may be issued without  registration under the Securities Act of 1933.
Neither the Company nor any of its  affiliates,  nor any person acting on its or
their  behalf,  has  engaged  in any form of  general  solicitation  or  general
advertising  (within the meaning of  Regulation D under the  Securities  Act) in
connection with any of the Shares.

               (s) Governmental Approvals. Except as set forth in the Commission
Documents or on Schedule 2.1(s) hereto,  and except for the filing of any notice

basis), including, but not limited to, the filing of a registration statement or
statements  pursuant to the Registration  Rights  Agreement,  no  authorization,
consent,  approval,  license exemption of, filing or registration with any court

instrumentality,  domestic  or  foreign,  is or will  be  necessary  for,  or in
connection with, the execution or delivery of the Shares, or for the performance
by the Company of its obligations under the Transaction Documents.

               (t)  Employees.  Neither the Company nor any  subsidiary  has any
collective bargaining  arrangements or agreements covering any of its employees,
except as set forth in the  Commission  Documents or on Schedule  2.1(t) hereto.
Except as set forth in the  Commission  Documents or on Schedule  2.1(t) hereto,

agreement,   confidentiality   agreement,  or  any  other  similar  contract  or
restrictive  covenant,  relating  to the  right  of  any  officer,  employee  or
consultant  to be employed or engaged by the Company or such  subsidiary.  Since
September 30, 2001, no officer, consultant or key employee of the Company or any
subsidiary whose  termination,  either  individually or in the aggregate,  could
have a Material  Adverse  Effect,  has  terminated  or, to the  knowledge of the
Company,  has any present  intention of  terminating  his or her  employment  or
engagement with the Company or any subsidiary.

               (u) Use of Proceeds. The proceeds from the sale of the Shares and
the  Warrants  will be used by the  Company  for  working  capital  and  general
corporate purposes.

               (v) Public Utility Holding Company Act and Investment Company Act
Status.  The Company is not a "holding company" or a "public utility company" as
such terms are defined in the Public  Utility  Holding  Company Act of 1935,  as
amended. The Company is not, and as a result of and immediately upon any Closing

company," within the meaning of the Investment Company Act of 1940, as amended.

               (w)  ERISA.  No  liability  to  the  Pension   Benefit   Guaranty
Corporation  has been incurred with respect to any Plan by the Company or any of
its subsidiaries  which is or would be materially adverse to the Company and its
subsidiaries.  The execution, delivery and performance of this Agreement and the
other  Transaction  Documents  and the  issue  and  sale of the  Shares  and the
Warrants will not involve any transaction  which is subject to the  prohibitions
of  Section  406 of ERISA or in  connection  with  which a tax could be  imposed
pursuant  to Section


                                       8


4975 of the Internal Revenue Code of 1986, as amended,  provided that, if any of
the Purchasers,  or any person or entity that owns a beneficial  interest in any
of the Purchasers,  is an "employee pension benefit plan" (within the meaning of
Section  3(2) of  ERISA)  with  respect  to which  the  Company  is a "party  in
interest"  (within the meaning of Section 3(14) of ERISA),  the  requirements of
Sections 407(d)(5) and 408(e) of ERISA, if applicable,  are met. As used in this

maintained,  or to which  contributions are or have been made, by the Company or
any subsidiary or by any trade or business, whether or not incorporated,  which,
together  with the  Company  or any  subsidiary,  is under  common  control,  as
described in Section 414(b) or (c) of the Code.

               (x)  No  Integrated  Offering.  To  the  best  of  the  Company's
knowledge, 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

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

               (a)  Organization  and  Standing of the  Purchasers.  Each of the
Purchasers 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  each of the
Purchasers was not formed for the specific purpose of acquiring the Securities.

               (b)  Authorization  and  Power.  Each of the  Purchasers  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 Purchasers 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  Purchasers  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 Purchasers 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 each
of the


                                       9


Purchasers  enforceable  against each of the  Purchasers 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  Purchasers 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  Purchasers.  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


                                       10


registration  is  available.  The Purchaser  acknowledges  that the Purchaser is
familiar with Rule 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, and has no knowledge  of the payment of, 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


                                       11


are duly licensed and/or registered to engage in securities offering and selling
activities (or are exempt from such licensing and/or 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

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

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

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

Warrants or the Warrant Shares.


                                       12


          Section 3.5 Other  Agreements.  The  Company  shall not enter into any

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 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
Purchasers'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 a  Purchasers  provides  the Company  with an
opinion of counsel, 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  Purchasers  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
Purchasers 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  Purchasers 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  Purchasers  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.

                            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,
prior to making any  transfer  of any Shares,  Warrants  or Warrant  Shares 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


                                       16


can be sold under Rule 144(k).  Each of the Purchasers  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 an exemption from the registration requirements of
the  Securities  Act or in accordance  with Rule 144(k).  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  Purchasers  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  Purchasers  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 Purchasers (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 Purchasers as a result of any breach of the covenants,  representations  and
warranties made by the Company herein. Each of the Purchasers agrees,  severally
and not jointly,  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 false  representation
or  warranty  or any  breach of the  covenants  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


                                       17


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 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

          Section 7.1 Fees,  Costs and  Expenses.  All fees,  costs and expenses

hereby will be paid by the party incurring such fees, costs and expenses.


                                       18


          Section  7.2  Consent to  Jurisdiction.  Each of the  Company  and the
Purchasers  (i) hereby  irrevocably  submits to the  jurisdiction  of the United
States  District  Court  sitting in the  Southern  District  of New York and the
courts of the State of New York  located in New York county for the  purposes of
any suit,  action or proceeding  arising out of or relating to this Agreement or
any  of  the  other  Transaction  Documents  or  the  transactions  contemplated
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 Purchasers 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.

          Section  7.3  Entire  Agreement;  Amendment.  This  Agreement  and the
exhibits  attached hereto contain the entire  understanding  of the parties with
respect to the matters  covered  hereby,  supersedes all prior  agreements  with
respect to subject matter hereof and, except as  specifically  set forth herein,
in the Shares or in the Warrants,  neither the Company nor any of the Purchasers
makes any  representations,  warranty,  covenant or undertaking  with respect to
such matters. No provision of this Agreement may be waived or amended other than
by a written instrument signed by the party against whom enforcement of any such
amendment or waiver is sought.

          Section 7.4  Notices.  Any notice,  demand,  request,  waiver or other
communication  required or permitted to be given  hereunder  shall be in writing

deemed  to be a  continuing  waiver  in the  future  or a  waiver  of any  other
provisions,  condition or requirement hereof, nor shall any delay or omission of
any party to exercise any right  hereunder in any manner  impair the exercise of
