                        AGREEMENT FOR PAYMENT OF ACCOUNT
                        --------------------------------

          AGREEMENT  FOR  PAYMENT  OF  ACCOUNT  dated as of June 4,  2002  (this
"Agreement"),  by and  between  XYBERNAUT  CORPORATION,  a Delaware  corporation
("Xybernaut"), and CARLTON R. TURNER., an individual ("Turner").

          WHEREAS,  Turner  and  Xybernaut  entered  into  a  Master  Consulting
Agreement  dated  February 1, 2002 (the "Master  Agreement"),  pursuant to which
Xybernaut engaged the services of Turner upon the terms and conditions contained
in the Master Agreement; and

          WHEREAS,  Xybernaut  wishes to reach an  agreement  on an  alternative
payment plan to compensate  Turner for balances owing to Turner arising from the
Master Agreement as of June 4, 2002; and

          WHEREAS,  Xybernaut and Turner have reached agreement on the terms and
provisions of such alternative payment plan.

          WHEREAS, Turner became an employee of Xybernaut on May 13, 2002.

          NOW, THEREFORE,  for good and valuable consideration,  the receipt and
legal sufficiency of which is hereby acknowledged, the parties agree as follows:

               1.  Balance:  The total  unpaid  balance of the  account  owed by
          Xybernaut  to Turner,  including,  but not limited  to, all  services,
          goods, expenses, and products provided by Turner to Xybernaut pursuant
          to the Master  Agreement,  through and up to June 4, 2002,  is for all
          purposes  agreed by the parties to be $9,068.18 (the  "Balance").  The
          Balance  excludes any  compensation  that may be owed to Turner in his
          capacity  as an employee of  Xybernaut  beginning  on May 13, 2002 and
          relates soley to balances accrued under the Master Agreement.





               2. Payment of Balance:  Turner will accept as payment in full for
          the Balance the  issuance of shares of  Xybernaut  common  stock,  par
          value $0.01 per share (the  "Common  Stock")  for the full  Balance as
          provided for herein (the "Stock Grant").

               3. Stock  Grant:  The Stock Grant will be  satisfied by Xybernaut
          issuing Ten Thousand Nine Hundred and Ninety Nine  (10,999)  shares of
          Common  Stock (the  "Shares")  to Turner based upon a value of $0.8245
          per share (the "Agreed Upon Value Per Share"), which amount represents
          a fifteen  percent (15%)  discount from the $0.97 closing market price
          of the Common  Stock on June 3, 2002 (the last  trading day  preceding
          the date of this  Agreement).  The issuance of the Stock Grant,  as is
          the case  with all  stock  grants  by  Xybernaut,  is  subject  to the
          approval of Xybernaut's Board of Directors. Promptly after the receipt
          of  such  approval,   Xybernaut   shall  cause  a  stock   certificate
          representing the Shares to be issued in the name of Carlton R. Turner.

               4. Registration of the Shares:  Xybernaut hereby grants to Turner
          "piggyback  registration  rights"  with  respect  to the  Shares to be
          issued to Turner  hereunder  in respect of the Stock Grant in the next
          registration  statement  filed by Xybernaut with respect to its Common
          Stock (other than a registration  statement on Form S-4 or Form S-8 or
          any  successor  thereto)  immediately  following  the  issuance of the
          Shares.  Xybernaut will furnish Turner with written notice  concerning
          any such  registration  statement  reasonably in advance of the filing
          thereof.  If Turner notifies  Xybernaut in writing,  such notice to be
          given  within  seven (7) business  days after  receipt of  Xybernaut's
          written notice,  that Turner desires its Shares to be included in such
          registration  statement  (which  request  shall  specify the number of
          Shares  that  Turner  wishes  to  have  included  in the  registration
          statement),  Xybernaut  shall use its reasonable best efforts to cause
          such Shares to be included in the registration  statement and to cause
          the registration  statement to be declared effective by the Securities
          and  Exchange  Commission  (the  "Commission").   Notwithstanding  the
          foregoing,  Xybernaut  shall have the right to exclude  such number of
          the  Shares  from  the  registration  statement  as  Xybernaut  or




          the managing underwriter(s),  if applicable,  may reasonably determine
          would  have an  adverse  affect  on the  registration  statement,  the
          likelihood  of the  Commission to declare the  registration  statement
          effective  or the  price to be  received  by  Xybernaut  or the  other
          selling  shareholders  for the other shares of Common Stock covered by
          the  registration  statement.  If  Xybernaut  cuts-back  the number of
          Shares  requested  by  Turner  to  be  included  in  the  registration
          statement for which Turner has  exercised  its piggyback  registration
          rights,  as permitted in the immediately  preceding  sentence,  Turner
          shall  continue to have piggyback  registration  rights for succeeding
          registration  statements until all of the Shares have been registered.
          Xybernaut  shall  be  responsible  for  the  compliance  of  any  such
          registration  statement with  applicable  securities laws until all of
          the  Shares  have  been  registered;  provided  that  Turner  shall be
          responsible for any information about Turner specifically  required by
          applicable  securities laws.  Turner shall indemnify and hold harmless
          Xybernaut (and its directors, officers, employees, control persons and
          agents and their  respective  successors and assigns) from and against
          any claim, action, suit, proceeding, damage, liability, loss, penalty,
          cost and expense (including without limitation,  reasonable attorneys'
          fees and  expenses)  incurred  by any of them as a result of, or based
          upon, a misstatement of a material fact or omission of a material fact
          regarding  Turner which is furnished to Xybernaut by Turner or omitted
          to be  furnished  to  Xybernaut  for  inclusion  in  any  registration
          statement  which  includes  any of the Shares.  All fees and  expenses
          incident  to  the  registration  of  the  Shares  shall  be  borne  by
          Xybernaut.  Notwithstanding anything set forth herein, Xybernaut shall
          not be required to include any Shares in a registration  statement, if
          such shares are eligible to be sold  pursuant to Rule 144  promulgated
          under the Securities  Act of 1933, as amended (the "Act"),  based upon
          the holding period for the Shares.

               5. Representations and Warranties: Turner represents and warrants
          to Xybernaut as follows:  (a) Turner is a  sophisticated  investor who
          either (i) has such knowledge and experience in financial and business
          matters  (including  without  limitation,   knowledge  and  experience
          investing in "restricted  securities",  as that term is defined in the
          Regulation D promulgated  under the Act, and the risks




          associated  with  such  an  investment)  such  that it is  capable  of
          evaluating  the merits and risks of its  investment in the Company and
          the  Shares,  (ii) has  obtained  independent  professional  financial
          advice, from a investment advisor, sufficient to enable it to evaluate
          the merits and risks of its  investment  in the  Company  and  Shares,
          and/or (iii) it is an  "accredited  investor,"  which is defined under
          Rule  501(a)(3) of the Act; (b) it is acquiring the Shares for its own
          account and not with a view to their  distribution  within the meaning
          of  Section  2(11)  of the Act;  (c) it has no  present  intention  to
          distribute  any of the Shares  publicly and has no present  agreement,
          understanding or arrangement to subdivide,  sell, assign,  transfer or
          otherwise  dispose of all or any of the Shares to any other  person or
          entity;  and (d) it  understands  that it may be necessary to bear the
          economic risk of the investment in the Shares for an indefinite period
          of time indefinitely because the Shares may not be sold, hypothecated,
          transferred,   pledged,   gifted  or  otherwise   disposed  of  unless
          registered  under the Act and all applicable  state securities laws or
          an exemption from such registration is available and is fully complied
          with by Turner.  Notwithstanding  the above, it is  acknowledged  that
          Turner may  publicly  sell  shares of Common  Stock in the open market
          without  restriction  through its broker if a  registration  statement
          covering the Shares is declared  effective by the Commission  pursuant
          to Section 5 hereof.  Turner  acknowledges  and agrees that  Xybernaut
          will be relying on the  representations  and  warranties of Turner set
          forth in this Section 6 in issuing the Shares which are the subject of
          the Stock Grant to Turner  pursuant to an exemption from  registration
          under the Act and applicable  state  securities  laws. The certificate
          for the Shares issued to Turner shall bear the  following  restrictive
          legend.

               "THESE  SECURITIES HAVE NOT BEEN  REGISTERED  UNDER THE
               SECURITIES  ACT OF 1933,  AS AMENDED  (THE  "ACT"),  OR
               APPLICABLE   STATE   SECURITIES  LAWS.  THE  SECURITIES
               REPRESENTED  BY THIS  CERTIFICATE  MAY NOT BE  OFFERED,
               SOLD,  TRANSFERRED,  HYPOTHECATED,  PLEDGED,  GIFTED OR
               OTHERWISE  DISPOSED OF, IN WHOLE OR IN PART, UNLESS THE
               SHARES ARE REGISTERED  UNDER THE ACT, OR IN THE ABSENCE
               OF A  REGISTRATION  STATEMENT IN EFFECT WITH RESPECT TO
               SUCH  SECURITIES   UNDER  THE  ACT,





               UNLESS   XYBERNAUT   CORPORATION  (THE  "COMPANY")  HAS
               RECEIVED THE WRITTEN  OPINION OF THE COMPANY'S  COUNSEL
               THAT,  AFTER   INVESTIGATION  OF  THE  RELEVANT  FACTS,
               COUNSEL  IS OF THE  OPINION  THAT SUCH  TRANSACTION  IS
               EXEMPT  FROM  REGISTRATION  UNDER  THE  ACT  AND  UNDER
               APPLICABLE STATE SECURITIES LAWS."

          this Agreement  Turner shall forebear and suspend any and all actions,
