                     Pursuant to Section 151 of the General

                    Corporation Law of the State of Delaware



                     ---------------------------------------

                            SERIES C PREFERRED STOCK

            Xybernaut  Corporation,  a Delaware corporation (the "Corporation"),
hereby  certifies  that the  following  resolution  has been duly adopted by the
Board of Directors of the Corporation:

                  RESOLVED,  that pursuant to the authority expressly granted to
            and  vested  in the Board of  Directors  of the  Corporation  by the
            provisions of the  Certificate of  Incorporation  of the Corporation
            (the "Certificate of Incorporation"),  there hereby is created,  out
            of the  6,000,000  shares of  Preferred  Stock,  par value $0.01 per
            share,  of the  Corporation  authorized  in  Article  Fourth  of the
            Certificate of Incorporation  (the "Preferred  Stock"),  a series of
            the  Preferred  Stock of the  Corporation  consisting of 375 shares,
            which  series  shall  have  the  following   powers,   designations,
            preferences and relative, participating,  optional and other rights,
            and the following qualifications, limitations and restrictions:

1.          Designation  and  Amount.  This series of  Preferred  Stock shall be
            designated  "Series C Preferred Stock" and the authorized  number of
            shares  constituting  such series shall be 375. The par value of the
            Series C  Preferred  Stock  shall be $0.01 per  share.  The Series C
            Preferred Stock shall have a stated value of $1,000 per share.

2.          Dividends.

                  (a) The holders of shares of Series C Preferred Stock shall be
            entitled to receive, out of any assets at the time legally available
            therefor  and  when  and as  declared  by the  Board  of  Directors,
            dividends at the rate of five percent (5%) of the stated Liquidation
            Preference  (as  defined  below) per share per  annum,  and no more,
            payable,  in  the  discretion  of  the  Board  of  Directors  of the
            Corporation  in shares of the common stock of the  Corporation,  par
            value  $0.01  per  share  (the  "Common  Stock"),  or in cash.  Such
            dividends  on the Series C Preferred  Stock shall be payable only at
            conversion of the Series






            C Preferred Stock into shares of Common Stock. Such dividends on the
            Series  C  Preferred  Stock  are  prior  and  in  preference  to any
            declaration or payment of any distribution (as defined below) on any
            outstanding shares of Common Stock or any other equity securities of
            the  Corporation  ranking  junior to the  Preferred  Stock as to the
            payment of dividends.  Such dividends  shall accrue on each share of
            Series C  Preferred  Stock  from day to day from the date of initial
            issuance  thereof  whether or not earned or declared so that if such
            dividends with respect to any previous  dividend  period at the rate
            provided for herein have not been paid on, or declared and set apart
            for, all shares of Series C Preferred Stock at the time outstanding,
            the  deficiency  shall be fully paid on, or  declared  and set apart
            for,  such  shares  on a  pro  rata  basis  with  all  other  equity
            securities of the Corporation ranking on a parity with the Preferred
            Stock as to the payment of dividends before any  distribution  shall
            be paid on, or declared  and set apart for Common Stock or any other
            equity securities of the Corporation ranking junior to the Preferred
            Stock as to the payment of dividends.

                  (b)  For  purposes  hereof,   unless  the  context   otherwise
            requires, "distribution" shall mean the transfer of cash or property
            without  consideration,  whether by way of  dividend  or  otherwise,
            payable  other  than in  shares  of  Common  Stock or  other  equity
            securities  of the Company,  or the purchase or redemption of shares
            of the Corporation  (other than redemptions set forth in Paragraph 5
            below  or   repurchases   of  Common  Stock  held  by  employees  or
            consultants of the Corporation  upon termination of their employment
            or services  pursuant to agreements  providing for such  repurchase)
            for cash or property.

3.          Preferences on Liquidation.

                  (a) In the event of any voluntary or involuntary  liquidation,
            dissolution, or winding up of the Corporation, the holders of shares
            of the Series C Preferred Stock then outstanding,  shall be entitled
            to be paid,  out of the  assets  of the  Corporation  available  for
            distribution to its stockholders,  whether from capital,  surplus or
            earnings,  before  any  payment  shall  be  made in  respect  of the
            Corporation's  Common  Stock,  an  amount  equal  to the  sum of one
            thousand  dollars  ($1,000.00) per share of Series C Preferred Stock
            (the  "Liquidation   Preference"),   plus  all  accrued  and  unpaid
            dividends thereon to the date of payment.

                  (b) If upon  liquidation,  dissolution,  or  winding up of the
            Corporation,   the   assets  of  the   Corporation   available   for
            distribution  to its  stockholders  shall be insufficient to pay the
            holders  of the  Series  C  Preferred  Stock  the  full  Liquidation
            Preference   plus  accrued  and  unpaid   dividends  to  which  they
            respectively  shall  be  entitled,  the  holders  of  the  Series  C
            Preferred  Stock  together  with the holders of any other  series of
            Preferred  Stock  ranking on a parity  with the  Series C  Preferred
            Stock as to the payments of amounts upon liquidation, dissolution or
            winding  up  shall  share  ratably  in any  distribution  of  assets
            according  to the  respective  amounts  which  would be  payable  in
            respect  of all  such  shares  held by the  respective  stockholders
            thereof  upon such  distribution  if all amounts  payable on or with
            respect to said shares were paid in full.

                  (c) For  purposes  of this  Paragraph  2,  the  sale or  other
            disposition  (for  cash,  shares  of  stock,   securities  or  other
            consideration),  of all or  substantially  all of the  assets of the
            Corporation  shall be deemed  to be a  liquidation,  dissolution  or
            winding up of the Corporation but the merger or consolidation of the
            Corporation  into  or with  another  corporation  into  or with  the
            Corporation, shall not be deemed to be a liquidation,  winding up or
            dissolution of the Corporation.


                                       2




                  (d) The  holders  of Series C  Preferred  Stock  shall have no
            priority or  preference  with respect to  distributions  made by the
            Corporation  in connection  with the  repurchase of shares of Common
            Stock issued to or held by employees,  directors or consultants upon
            termination of their  employment or services  pursuant to agreements
            providing for the right of said  repurchase  between the Corporation
            and such persons.

4.          Conversion Rights.

                  The holders of Series C Preferred  Stock shall have conversion
rights as follows:

                  (a) No  shares of Series C  Preferred  Stock may be  converted
            prior to August 15, 1998.  At any time after August 15, 1998 through
            November 14, 1998, up to twenty-five  (25%) percent of the shares of
            Series C Preferred Stock then  outstanding may be converted,  at the
            option of the holders thereof,  and thereafter on November 15, 1998,
            February 15, 1999 and May 15, 1999, an additional  twenty-five (25%)
            percent of the shares of Series C Preferred  Stock then  outstanding
            may be converted,  on a cumulative and pro rata basis, at the option
            of the  holders  thereof.  The  number of  shares of fully  paid and
            nonassessable  Common  Stock  into  which  each  share  of  Series C
            Preferred Stock may be converted shall be determined by dividing the
            Liquidation  Preference  by the  Conversion  Price  (as  hereinafter
            defined) in effect on the Conversion Date.

                  (b) For purposes of this Paragraph 4, (i)  "Conversion  Price"
            means an amount equal to the lesser of (a) 100 percent (100%) of the
            average  closing bid price of the Common Stock as reported by Nasdaq
            Small Cap Market or any successor exchange in which the Common Stock
            is listed for the five (5) trading  days  preceding  the  Conversion
            Date, or (b) Four ($4.00) Dollars;  and (ii) "Conversion Date" means
            the date on which the  holder of the  Series C  Preferred  Stock has
            telecopied the Notice of Conversion (as hereinafter  defined) to the
            Corporation.

                  (c) A holder  may  convert  in whole or in part,  the Series C
            Preferred Stock into Common Stock held by such holder by telecopying
            an executed and  completed  Notice of Conversion in the form annexed
            hereto as Exhibit A (a "Notice of  Conversion")  to the  Corporation
            and delivering the original Notice of Conversion and the certificate
            representing   the  shares  of  Series  C  Preferred  Stock  to  the
            Corporation  by express  courier within five (5) business days after
            the date of the Notice of Conversion. Each date on which a Notice of
            Conversion  is  telecopied  to and  received by the  Corporation  in
            accordance  with the provisions  hereof shall be deemed a Conversion
            Date. The Corporation  will transmit the  certificates  representing
            the Common Stock issuable upon  conversion of all or any part of the
            shares of Series C Preferred  Stock  (together with the  certificate
            representing  portions of the shares of Series C Preferred Stock not
            so  converted)  to the holder via  express  courier  within five (5)
            business days after the Corporation has received the original Notice
            of Conversion and shares certificate being so converted.  The Notice
            of Conversion and certificate representing the portion of the shares
            of Series C Preferred  Stock  converted  shall be  delivered  to the
            Corporation  at its  principal  executive  offices  or to such other
            person at such  other  place as the  Corporation  designates  to the
            holder in  writing.  In the event the  shares of Series C  Preferred
            Stock are not converted  within ten (10) business days of receipt by
            the  Corporation  of a valid Notice of Conversion  and  certificates
            representing the shares of Series C Preferred Stock to be converted,
            the  Corporation  shall  pay to the  holder,  by wire  transfer,  as
            liquidated damages for such failure and not as a penalty,  an amount
            in cash equal to one (1%) percent per day of the  purchase  price of
            the shares of Series C Preferred  Stock to be converted  which shall
            run from the initial  Conversion  Date and the holder has the option
            to withdraw the Notice of Conversion previously sent;


                                       3




            provided,  that the  Corporation  shall  not be  responsible  for or
            required to pay such  liquidated  damages if such failure to convert
            was not caused by any actions or omissions of the Corporation.

                  (d) No fractional  shares of Common Stock shall be issued upon
            conversion  of  the  Series  C  Preferred  Stock.  In  lieu  of  any
            fractional  shares to which the holder would  otherwise be entitled,
            the Corporation shall pay cash equal to such fraction  multiplied by
            the fair market value of the Common Stock on the Conversion Date, as
            determined by the Corporation's Board of Directors.  The Corporation
            shall not be obligated to issue  certificates  evidencing the shares
            of  Common  Stock  issuable  upon   conversion   unless  either  the
            certificates  evidencing such shares of Series C Preferred Stock are
            delivered  to the  Corporation  or its  transfer  agent as  provided
            above,  or the holder notifies the Corporation or its transfer agent
            that such  certificates  have been  lost,  stolen or  destroyed  and
            executes an agreement  satisfactory  to the Corporation to indemnify
            the Corporation from any loss incurred by it in connection with such
            certificates.

                  (e) Subject to subparagraph (b) above, the Corporation  shall,
            as soon as practicable after such delivery,  or after such agreement
            and indemnification, issue and deliver at such office to such holder
            of Series C Preferred  Stock, a certificate or certificates  for the
            number  of  shares of  Common  Stock to which  the  holder  shall be
            entitled as aforesaid and a check  payable to the holder,  or order,
            in the  amount  of any  cash  amounts  payable  as the  result  of a
            conversion into fractional  shares of Common Stock, plus any accrued
            and unpaid  dividends on the converted Series C Preferred Stock, and
            a  certificate  for any  shares of Series C  Preferred  Stock not so
            converted.

                  (f) Upon any  conversion of Series C Preferred  Stock pursuant
            to this Paragraph 4 the shares of Series C Preferred Stock which are
            converted  shall  not  be  reissued  and  shall  not  be  considered
            outstanding  for any  purposes.  Upon  conversion of all of the then
            outstanding  Series C Preferred  Stock  pursuant to this Paragraph 4
            and upon the taking of any action  required by law,  all matters set
            forth in this  Certificate of Designation  shall be eliminated  from
            the Certificate of Incorporation, shares of Series C Preferred Stock
            shall not be deemed  outstanding for any purpose  whatsoever and all
            such shares shall be retired and canceled and shall not be reissued.

                  (g) Any  transmittal or other  communications  required by the
            provisions of this  Paragraph 4 to be given to the holders of shares
            of Series C Preferred  Stock shall be deemed  given if  deposited in
            the United States mail,  first class,  postage prepaid and addressed
            to each  holder of record at its address  appearing  on the books of
            the Corporation.

                  (h) On May 15,  2000,  the holder shall be required to convert
            all of its  outstanding  shares of  Series C  Preferred  Stock  into
            shares of Common Stock. Until converted in accordance with the terms
            of this  Paragraph 4, the Company shall be entitled to redeem shares
            of Series C Preferred  Stock in accordance  with Paragraph 5 hereof,
            regardless  of  whether  or not a  Notice  of  Conversion  has  been
            received by the Corporation with respect to such shares.

                  (i) The  Corporation  shall at all  times  when any  shares of
            Series C  Preferred  Stock  shall be  outstanding,  reserve and keep
            available out of its authorized but unissued  stock,  such number of
            shares of Common Stock as shall from time to time be  sufficient  to
            effect  the  conversion  of  all  outstanding  shares  of  Series  C
            Preferred Stock.

5.          Redemption.

                  (a) At any time after May 15, 1998,  the  Corporation  may, at
            the  option  of the  Board of  Directors,  redeem  up to 100% of the
            outstanding shares of the Series C Preferred Stock at the redemption
            price set forth in subparagraph  (b) below,  provided,  that (x) the
            Corporation shall have received a Notice of Conversion,  and (y) the
            Conversion Price is below $3.40. The Corporation  shall give written
            notice by telecopy,  to the holder of Series C Preferred Stock to be
            redeemed at least one (1) business  day after  receipt of the Notice
            of  Conversion  prior  to the date  specified  for  redemption  (the
            "Redemption  Date").  Such notice  shall be  addressed  to each such
            stockholder at the address of such holder  appearing on the books of
            the  Corporation or given by such holder to the  Corporation for the
            purpose of notice,  or if no such address appears or is so given, at
            the place where the principal  office of the Corporation is located.
            Such notice shall state the Redemption  Date,  the Redemption  Price
            (as hereinafter defined), the number of shares of Series C Preferred
            Stock of such  holders  to be  redeemed  and  shall  call  upon such
            holders to surrender to the  Corporation on the  Redemption  Date at
            the place designated in the notice such holders'  redeemed stock. If
            fewer than all the  outstanding  shares of Series C Preferred  Stock
            are to be  redeemed,  the  redemption  shall be pro rata  among  the
            holders  of Series C  Preferred  Stock  and  subject  to such  other
            provisions  as may be  determined  by the  Board of  Directors.  The
            Redemption Date shall be no more than ten (10) days after receipt of
            written notice from the Corporation. If the Corporation fails to pay
            the Redemption Price on the Redemption  Date, the Corporation  shall
            pay to the  holder a penalty  in an amount in cash equal to two (2%)
            percent of the Redemption  Price to be paid on such Redemption Date.
            If  the  Corporation  fails  to  pay  the  Redemption  Price  on the
            Redemption  Date,  the holder  shall  have the right to convert  the
            Series C Preferred Stock previously presented to the Corporation and
            not  redeemed.  The  Corporation  shall have the right to redeem the
            Series C  Preferred  Stock  in  accordance  with  the  terms of this
            subparagraph (a) in any subsequent  redemption;  provided,  however,
            that if the  Corporation  fails  to pay the  Redemption  Price  in a
            subsequent  redemption  within ten (10) days, the Corporation  shall
            have the right to redeem the Series C  Preferred  Stock  thereafter,
            only upon wiring the Redemption Price to the holders  simultaneously
            with sending the notice of  redemption.  On or after the  Redemption
            Date,  the holders of shares of Series C Preferred  Stock called for
            redemption  shall surrender the  certificates  evidencing the shares
            called for redemption to the Corporation at the place  designated in
            such notice and shall  thereupon  be entitled to receive  payment of
            the Redemption Price.

                  (b) Subject to the terms of Paragraph 5(a) above,  the Company
            shall  have  the  option  to  redeem  all or a  portion  of all  the
            outstanding shares of Series C Preferred Stock at a cash price equal
            to  $3.40  multiplied  by  the  number  of  shares  the  Convertible
            Preferred  Stock would convert into on the date of  redemption  (the
            "Redemption Price").

                  (c) From and after the Redemption  Date (unless  default shall
            be made by the  Corporation in duly paying the  Redemption  Price in
            which  case all the  rights  of the  holders  of such  shares  shall
            continue), the holders of the shares of the Series C Preferred Stock
            called for redemption shall cease to have any rights as stockholders
            of the Corporation,  except the right to receive,  without interest,
            the  Redemption   Price  thereof  upon  surrender  of   certificates
            representing the shares of Series C Preferred Stock, and such shares
            shall not thereafter be transferred  (except with the consent of the
            Corporation) on the books of the Corporation and shall not be deemed
