                          COMMON STOCK PURCHASE WARRANT

                              XYBERNAUT CORPORATION

                            EXPIRES NOVEMBER 13, 2005

No.:  W-N02-3                                        Number of Shares: 2,135,417
Date of Issuance:  November 13, 2002


         1. Issuance. For good and valuable consideration,  the receipt of which
is hereby  acknowledged by Xybernaut  Corporation,  a Delaware  corporation (the
"Company"),  State Street Corporation,  or its registered assigns (the "Holder")
is hereby  granted the right to  purchase at any time until 5:00 P.M.,  New York
City time, on November 13, 2005 (the "Expiration Date"), Two Million One Hundred
Thirty-Five Thousand Four Hundred Seventeen  (2,135,417) shares of the Company's
Common  Stock,  par value  $.01 per share  (the  "Common  Stock")  at an initial
exercise  price of $1.25 per share (the  "Exercise  Price"),  subject to further
adjustment as set forth in Section 6 hereof.

         2.  Exercise of Warrants.  This Warrant is  exercisable  in whole or in
part at the Exercise Price per share of Common Stock payable hereunder,  payable
in cash or by certified or official bank check.  Upon  surrender of this Warrant
Certificate  with the annexed  Notice of Exercise Form duly  executed,  together
with payment of the Exercise Price for the shares of Common Stock purchased, the
Holder shall be entitled to receive a certificate or certificates for the shares
of Common Stock so purchased.

         3.  Reservation of Shares.  The Company hereby agrees that at all times
during the term of this  Warrant  there  shall be  reserved  for  issuance  upon
exercise of this  Warrant  such number of shares of its Common Stock as shall be
required for issuance upon exercise of this Warrant (the "Warrant Shares").

         4.  Mutilation  or Loss of  Warrant.  Upon  receipt  by the  Company of
evidence  satisfactory  to it of the loss,  theft,  destruction or mutilation of
this  Warrant,  and (in the  case of  loss,  theft or  destruction)  receipt  of
reasonably  satisfactory  indemnification,  and (in the case of



mutilation)  upon surrender and  cancellation of this Warrant,  the Company will
execute  and  deliver a new  Warrant  of like  tenor and date and any such lost,
stolen, destroyed or mutilated Warrant shall thereupon become void.

         5. Rights of the Holder.  The Holder  shall not, by virtue  hereof,  be
entitled to any rights of a stockholder in the Company, either at law or equity,
and the rights of the Holder are limited to those  expressed in this Warrant and
are not enforceable against the Company except to the extent set forth herein.

         6. Protection Against Dilution.
            ---------------------------

            (a) Adjustment Mechanism.  If an adjustment of the Exercise Price is
required  pursuant to this  Section 6, the Holder  shall be entitled to purchase
such  number of  additional  shares of Common  Stock as will cause (i) the total
number of shares of Common Stock Holder is entitled to purchase pursuant to this
Warrant,  multiplied  by (ii) the adjusted  purchase  price per share,  to equal
(iii) the dollar  amount of the total number of shares of Common Stock Holder is
entitled to purchase  before  adjustment  multiplied by the total purchase price
before adjustment.

            (b) Capital Adjustments. In case of any stock split or reverse stock
split, stock dividend,  reclassification of the Common Stock,  recapitalization,
merger or consolidation,  or like capital adjustment  affecting the Common Stock
of the  Company,  the  provisions  of this Section 6 shall be applied as if such
capital  adjustment  event had  occurred  immediately  prior to the date of this
Warrant and the original  purchase price had been fairly  allocated to the stock
resulting from such capital adjustment;  and in other respects the provisions of
this Section 6 shall be applied in a fair, equitable and reasonable manner so as
to give effect,  as nearly as may be, to the purposes  hereof. A rights offering
to stockholders of the Company shall be deemed a stock dividend to the extent of
the bargain purchase element of the rights.

         7.  Warrant  Call.  At  any  time  or  from  time  to  time  after  the
Registration  Statement  (as defined in Section 9(b)  hereof) has been  declared
effective,  the Company,  at its option,  may, upon written notice to the Holder
(the "Call  Notice"),  call up to one hundred  percent (100%) of this Warrant if
the Common  Stock trades at a price equal to or greater than $2.50 per share for
five (5)  consecutive  trading  days  prior to the date the  Company  calls  the
Warrant.  To be  effective,  the Call Notice must be given  within ten (10) days
after the aforementioned  five (5) day period. The rights and privileges granted
pursuant to this Warrant with respect to such Warrant Shares subject to the Call
Notice shall  terminate if this  Warrant is not  exercised  with respect to such
Warrant  Shares by the  Holder  within  ten (10) days  after the Call  Notice is
received by the Holder.  In the event that this Warrant is not  exercised by the
Holder  with  respect to the Warrant  Shares  subject to the Call  Notice,  this
Warrant shall expire at 5:00 p.m.  eastern time on the call date and the Company
will remit to the Holder $0.01 per Warrant  Share and a new Warrant  certificate
representing  the number of Warrant  Shares,  if any, with respect to which this
Warrant  has not been  exercised  or subject to a Call  Notice  upon such Holder
tendering to the Company the expired Warrant certificate.

         8. Limitation on Exercise. Notwithstanding anything to the contrary set
forth in this Warrant or the Common Stock and Warrant Purchase Agreement of even
date herewith



(the  "Purchase  Agreement"),  the Holder shall not be entitled to exercise this
Warrant and the Company shall have no obligation to issue shares of Common Stock
upon such  exercise  of all or any portion of this  Warrant to the extent  that,
following such exercise,  the Beneficial  Ownership Number (as defined below) is
equal to or  greater  than  4.99% of the  outstanding  shares  of  Common  Stock
(including  the  shares  to  be  issued  to  the  Holder  upon  such  exercise).
Notwithstanding  the  foregoing,  this Section 8 shall have no further force and
effect if there is an  outstanding  tender offer for any or all of the shares of
the Company's  Common  Stock,  or the Holder,  at its option,  provides at least
sixty-five (65) days' advance written notice from the Holder that this Section 8
shall  have  no  further  force  and  effect.  For  purposes  of  this  Section,
"Beneficial Ownership Number" shall equal the sum of (i) the number of shares of
Common Stock owned by the Holder and its affiliates (other than shares of Common
Stock  which may be deemed  beneficially  owned  through  the  ownership  of the
unexercised  portion of the Warrant or other rights to purchase  Common Stock or
through the ownership of convertible securities),  and (ii) the number of shares
of Common Stock issuable upon the exercise of the Warrant.  For purposes of this
Section,  "beneficial  ownership" shall be determined in accordance with Section
13(d) of the  Securities  Exchange Act of 1934, as amended.  The Holder,  by its
acceptance  of this  Warrant,  further  agrees that if the Holder  transfers  or
assigns any of the Warrants to any party,  such assignment shall be made subject
to  the  transferee's  or  assignee's  specific  agreement  to be  bound  by the
provisions of this Section 8 as if such transferee or assignee were the original
Holder hereof.

         9. Transfer to Comply with the Securities Act; Registration Rights.
            ---------------------------------------------------------------

            (a) This Warrant has not been registered under the Securities Act of
1933, as amended (the "Act"),  or any applicable  state securities laws, and has
been issued to the Holder for investment and not with a view to the distribution
of either the Warrant or the Warrant Shares. Neither this Warrant nor any of the
Warrant  Shares or any other  security  issued or issuable upon exercise of this
Warrant may be sold,  transferred,  pledged or hypothecated in the absence of an
effective  registration  statement under the Act relating to such security or an
opinion of counsel satisfactory to the Company that registration is not required
under the Act.  Each  certificate  for the Warrant,  the Warrant  Shares and any
other security  issued or issuable upon exercise of this Warrant shall contain a
legend on the face thereof,  in form and substance  satisfactory  to counsel for
the  Company,  setting  forth the  restrictions  on transfer  contained  in this
Section.

            (b) The Company agrees to file a registration statement, which shall
include  the  Warrant  Shares,  on  Form  S-3 or  another  available  form  (the
"Registration Statement"), pursuant to the Registration Rights Agreement between
the Company  and the Holder  dated as of  November  13, 2002 (the  "Registration
Rights Agreement").
