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"), Alpha Capital Aktiengesellschaft, 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"),  Four
Hundred  Sixty-Eight  Thousand  Seven  Hundred  Fifty  (468,750)  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



                                       2


have owned or have been  entitled to receive had such Warrant been  exercised in
advance  thereof.  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.

          11. Transfer to Comply with the Securities Act; Registration Rights.

              11.1 This Warrant has not been registered under the Securities Act
