     This COMMON STOCK AND WARRANT PURCHASE AGREEMENT dated as of March 13, 2002
(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  1,875,000 shares of the Company's
common  stock,  par value $.01 per share (the "Common  Stock"),  and warrants to
purchase up to in the aggregate  468,750 shares of Common Stock purchased by the
Purchasers,  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 Purchasers  and the Purchasers  shall purchase from the Company an aggregate
of 1,875,000  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 $1.60

covenants to continue to reserve,  free of  preemptive  rights and other similar

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

Shares set forth  opposite their  respective  names on Exhibit A, 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

Company  shall issue to the  Purchasers  Warrants to  purchase an  aggregate  of
468,750  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  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 (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, 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,  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 which is likely to materially  hinder


                                       2


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  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
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  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 or financial condition,
which,  under applicable law, rule or regulation,  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)

subsidiaries  have  all  franchises,   permits,  licenses,  consents  and  other

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 be filed

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

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

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.

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 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

     The  Company  covenants  with  each of the  Purchasers,  for so long as the
Shares and/or the Warrants remain  outstanding,  as follows (which covenants are
for the benefit of the Purchasers 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 Purchasers 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  Purchasers  set forth herein in order to  determine  the  applicability  of
federal  and  state  securities  laws  exemptions  and  the  suitability  of the
Purchasers 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.



                                       12


     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.

     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 each of the Purchasers
or its  respective  nominee(s),  for the Shares and the  Warrant  Shares in such
amounts as  specified  from time to time by each  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 tot he 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 a 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
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.

decree,  ruling or injunction shall have been enacted,  entered,  promulgated or
endorsed by any court or governmental  authority of competent jurisdiction which
prohibits  the  consummation  of any of the  transactions  contemplated  by this
Agreement.

     Section 4.2  Conditions  Precedent to the  Obligation of the  Purchasers to
Purchase the Shares at the Closing.  The obligation  hereunder of each Purchaser
to acquire and pay for the Shares and Warrants is subject to the satisfaction or
waiver,  at or before the Closing,  of each of the  conditions  set forth below.
These conditions are for each Purchaser's sole benefit and may be waived by such
Purchaser at any time in its sole discretion.

          (a) Accuracy of the Company's Representations and Warranties.  Each of
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
made at that time (except for  representations and warranties that speak as of a
particular date), which shall be true and correct in all material respects as of
such date.

          (b)  Performance  by the Company.  The Company  shall have  performed,
satisfied and complied in all material  respects with all covenants,  agreements
and conditions required by this Agreement to be performed, satisfied or complied
with by the Company at or prior to the Closing.

          (c) No  Suspension,  Etc.  From the date hereof to the  Closing  Date,
trading in the  Company's  Common  Stock  shall not have been  suspended  by the
Commission,  and, at any



                                       14


time prior to the Closing Date,  trading in securities  generally as reported by
Bloomberg  Financial  Markets  ("Bloomberg")  shall not have been  suspended  or
limited,  or minimum prices shall not have been  established on securities whose
trades are reported by Bloomberg, or on the New York Stock Exchange, nor shall a
banking  moratorium have been declared either by the United States,  or New York
State  authorities,  nor shall  there have  occurred  any  material  outbreak or
escalation of hostilities or other national or international  calamity or crisis
of such magnitude in its effect on, or any material adverse change in the United
States financial market which, in each case, in the judgment of such Purchasers,
makes it impracticable or inadvisable to acquire the Shares and the Warrants.

          (d) No Injunction.  No statute,  rule,  regulation,  executive  order,
decree,  ruling or injunction shall have been enacted,  entered,  promulgated or
endorsed by any court or governmental  authority of competent jurisdiction which
prohibits  the  consummation  of any of the  transactions  contemplated  by this
Agreement.

          (e) No Proceedings or Litigation. No action, suit or proceeding before
any arbitrator or any governmental  authority shall have been commenced,  and no
investigation by any governmental authority shall have been threatened,  against
the Company,  or any of the  officers,  directors or  affiliates  of the Company
seeking to restrain,  prevent or change the  transactions  contemplated  by this
Agreement, or seeking damages in connection with such transactions.

          (f) Opinion of Counsel, Etc. At the Closing, the Purchasers shall have
received an opinion of counsel to the Company,  dated the date of such  Closing,
in the form of Exhibit D hereto.

deliver  to the  Purchasers,  the  certificates  (in such  denominations  as the
Purchasers  shall  request) for the Shares and the Warrants  being  purchased by
such Purchasers as soon as practicable following the Closing.

          (i) Resolutions.  Prior to the Closing,  the Board of Directors of the
Company shall have adopted resolutions consistent with Section 2.1(b) above in a
form reasonably acceptable to the Purchasers (the "Resolutions").

          (j)  Reservation of Shares.  As of the Closing Date, the Company shall
have reserved out of its  authorized and unissued  Common Stock,  solely for the
purpose  of  effecting  the  issuance  of the  Shares  and the  exercise  of the
Warrants,  a number  of shares of  Common  Stock  equal to at least  100% 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
date  regardless of any  limitation on the timing or amount of such issuances or
exercises).



                                       15


          (k)  Transfer  Agent  Instructions.   As  of  the  Closing  Date,  the

                                   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,
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 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



                                       16


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  any  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 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


                                       17


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 7.2 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



                                       18


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.

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.
