Date of Issuance:  March 13, 2002


     1.  Issuance.  In  consideration  of good and valuable  consideration,  the
receipt of which is hereby  acknowledged  by Xybernaut  Corporation,  a Delaware
corporation (the "Company"),  Cranshire Capital, L.P., 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 March 13,  2006 (the  "Expiration  Date"),  Three
Hundred  Twelve  Thousand Five Hundred  (312,500)  fully paid and  nonassessable
shares (the "Warrant  Shares") of the Company's Common Stock, par value $.01 per
share (the "Common  Stock"),  at an exercise  price (the  "Exercise  Price") per
share equal to $3.00.  The Exercise Price and the number of shares for which the
Warrant is exercisable  shall be subject to adjustment as provided herein.  This
Warrant is being issued in connection with the Common Stock and Warrant Purchase
Agreement  dated as of March 13, 2002 (the  "Agreement"),  and is subject to its
terms and  conditions.  In the event of any  conflict  between the terms of this
Warrant and the Agreement, the Agreement shall control.

     2. Exercise of Warrants. Except as provided in Section 4 below, exercise of
the  purchase  rights  represented  by this  Warrant  may be made at any time or
times, before the close of business on the Expiration Date, or such earlier date
on which  this  Warrant  may  terminate  as  provided  in this  Warrant,  by the
surrender  of this Warrant and the Notice of Exercise  Form annexed  hereto duly
executed,  at the office of the Company  (or such other  office or agency of the
Company as it may designate by notice in writing to the registered holder hereof
at the address of such holder  appearing  on the books of the  Company) and upon
payment of an amount of consideration therefor payable by (i) certified check or
cashier's  check or by wire transfer to an account  designated by the Company in
an amount equal to the Exercise Price multiplied by the number of Warrant Shares
purchased,  (ii) if the



Registration  Statement  (as  defined in the  Agreement)  has not been  declared
effective  by March 12, 2003,  by  "cashless  exercise",  by  surrendering  this
Warrant certificate to the Company to receive a number of shares of Common Stock
equal to (A) the number of Warrant  Shares  with  respect to which the Holder is
exercising this Warrant minus (B) the number of Warrant Shares which is equal to
the quotient  obtained by dividing (x) the product of the Exercise Price and the
number of Warrant  Shares being  purchased upon such exercise by (y) the closing
bid  price  of the  Common  Stock  on the  date of such  exercise  or (iii) by a
combination  of the  foregoing  methods.  In any case  where  the  consideration
payable  upon such  exercise  is being paid in whole or in part  pursuant to the
provisions of clause (ii),  such exercise shall be accompanied by written notice
from the Holder of this  Warrant  specifying  the manner of payment  thereof and
containing a calculation  (in accordance with  clause(ii)(B)  of this Section 2)
showing  the number of Warrant  Shares  with  respect to which  rights are being
surrendered  thereunder (the "Surrendered  Shares") and the net number of shares
of Common Stock to be issued after giving effect to such surrender.  The Company
shall cancel this Warrant with respect to any Surrendered  Shares.  In the event
of an exercise of this  Warrant in  accordance  with this  Section 2, the Holder
shall be  entitled to receive a  certificate  for the number of shares of Common
Stock  so  purchased.  Certificates  for  shares  purchased  hereunder  shall be
delivered to the Holder  hereof within three (3) business days after the date on
which this Warrant shall have been exercised as aforesaid.

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

     4.  No  Fractional   Shares  or  Scrip.  No  fractional   shares  or  scrip
representing  fractional  shares  shall  be  issued  upon the  exercise  of this
Warrant.

     5. Loss, Theft,  Destruction or Mutilation 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.

     6.  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.

     7.  Adjustments of Exercise Price and Number of Warrant Shares.  The number
and kind of  securities  purchasable  upon the  exercise of this Warrant and the
Exercise  Price  shall be  subject  to  adjustment  from  time to time  upon the
happening of any of the following.

     In case the Company shall (i) declare or pay a dividend in shares of Common
Stock or make a  distribution  in  shares  of  Common  Stock to  holders  of its
outstanding Common Stock, (ii) subdivide its outstanding shares of Common Stock,
(iii) combine its  outstanding  shares of Common Stock into a smaller  number of
shares  of Common  Stock or (iv)  issue any  shares  of its  capital  stock in a
reclassification  of the  Common  Stock,  then  the  number  of  Warrant  Shares
purchasable  upon  exercise of this Warrant  immediately  prior thereto shall be
adjusted so that the Holder  shall be entitled to receive the kind and number of
Warrant  Shares or other  securities of the Company which he would have owned or
have been  entitled  to  receive  had such  Warrant  been  exercised  in advance
thereof.


                                       2


Upon each such  adjustment  of the kind and  number of  Warrant  Shares or other
securities  of the Company  which are  purchasable  hereunder,  the Holder shall
thereafter  be  entitled  to  purchase  the  number of  Warrant  Shares or other
securities  resulting from such adjustment at an Exercise Price per such Warrant
Share or other  security  obtained by  multiplying  the Exercise Price in effect
immediately prior to such adjustment by the number of Warrant Shares purchasable
pursuant hereto  immediately prior to such adjustment and dividing by the number
of  Warrant  Shares  or other  securities  of the  Company  resulting  from such
adjustment.

     An  adjustment  made  pursuant  to this  section 7 shall  become  effective
immediately  after the effective  date of such event  retroactive  to the record
date, if any, for such event.

     8. Intentionally Omitted.

     9. Notice of Adjustment. Whenever the number of Warrant Shares or number or
kind of  securities  or other  property  purchasable  upon the  exercise of this
Warrant or the Exercise Price is adjusted as herein provided,  the Company shall
promptly mail by registered or certified mail, return receipt requested,  to the
Holder  notice of such  adjustment  or  adjustments  setting forth the number of
Warrant Shares (and other securities or property)  purchasable upon the exercise
of this  Warrant  and the  Exercise  Price of such  Warrant  Shares  (and  other
securities or property) after such  adjustment,  setting forth a brief statement
of the facts  requiring  such  adjustment  and setting forth the  computation by
which such adjustment was made. Such notice, in absence of manifest error, shall
be conclusive evidence of the correctness of such adjustment.

     10.  Warrant Call. At any time or from time to time after the  Registration
Statement  (as defined in Section 11.2 hereof) has been  declared  effective and
after any  lock-up  period  relating  to the  Warrant  Shares has  expired,  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 volume
weighted  average price for the Common Stock (using the Bloomberg VWAP function)
is equal to or  greater  than $3.50 per share for ten (10)  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 ten (10) 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.
