                           CERTIFICATE OF DESIGNATION
                                       OF
                              XYBERNAUT CORPORATION

                     Pursuant to Section 151 of the General
                    Corporation Law of the State of Delaware

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

                            SERIES E 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 2,000 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 E Preferred Stock" and the authorized number of
         shares constituting such series shall be 2,000. The par value of the
         Series E Preferred Stock shall be $0.01 per share. The Series E
         Preferred Stock shall have a stated value of $1,000 per share.

2.       DIVIDENDS.

                  a. The holders of shares of Series E 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 E Preferred
         Stock shall be payable only at conversion of the Series E Preferred
         Stock into shares of Common Stock. Such dividends on the Series E
         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 Series E Preferred Stock as to the
         payment of dividends. Such dividends shall accrue on each share of
         Series E 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 E Preferred Stock at the time outstanding,
         the

                                      E-13





         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 Series E 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 Series E 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
         Corporation, 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 E 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 E 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 E Preferred Stock the full Liquidation Preference plus accrued
         and unpaid dividends to which they respectively shall be entitled, the
         holders of the Series E Preferred Stock together with the holders of
         any other series of Preferred Stock ranking on a parity with the Series
         E 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.

                  d. The holders of Series E 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 E Preferred Stock shall have conversion
rights as follows:

                  a. No shares of Series E Preferred Stock may be converted
         prior to the earlier of (i) the effective date of the registration
         statement covering the shares of Common Stock issuable upon conversion
         of the Series E Preferred Stock, and (ii) on the one hundred
         twenty-first (121st) day after the Closing Date (as hereinafter
         defined) (the "First Conversion Date"). During the thirty-day period
         following the First Conversion Date, up to twenty-five (25%) percent of
         the shares of Series E Preferred Stock then outstanding may be
         converted, at the option of the holders thereof, and during each
         thirty-day period thereafter, an additional twenty-five (25%) percent
         of the shares of Series E Preferred Stock issued on the Closing Date
         may be converted, on a cumulative (by taking into account the number of
         unconverted shares of Preferred Stock which were permitted to be
         converted during the prior thirty-day periods) and pro rata basis, at
         the option of the holders thereof. Notwithstanding the foregoing, if
         the trading volume of the Common Stock for the two weeks prior to the
         First Conversion Date equals or exceeds 150,000, during each thirty day
         period following the First Conversion Date up to thirty-three percent
         (33%) of the Series E Preferred Stock 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 E 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 (as hereinafter
         defined).

                  b. For purposes of this Paragraph 4, (i) "Conversion Price"
         means an amount equal to the lesser of (a) one hundred percent (100%)
         of the closing bid price of the Common Stock as reported by Bloomberg
         L.P. on the trading day immediately preceding the Closing Date (as such
         term is defined in the Securities Purchase Agreement dated as of May
         11, 1999 (the "Securities Purchase Agreement")), or (b) ninety-four
         percent (94%) of the "Market Price," where "Market Price" is defined as
         the average of the three (3) lowest closing bid prices, not necessarily
         consecutive, of the Common Stock during the twenty (20) day trading
         period immediately preceding the Conversion Date; and (ii) "Conversion
         Date" means the date on which the holder of the Series E Preferred
         Stock has telecopied the Notice of Conversion (as hereinafter defined)
         to the Corporation, which date shall not be prior to the earlier of:
         (a) the effective date of the registration statement or (b) on the one
         hundred twenty-first (121st) day after the Closing Date.

                  c. A holder may convert in whole or in part, the Series E
         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 (at Fax
         Number 703-222-7660 Attention: Steven Newman and Jeffrey Pagano) to the
         Corporation and delivering the original Notice of Conversion and the
         certificate representing the shares of Series E 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 E Preferred Stock (together with the certificate representing
         portions of the shares of Series E Preferred Stock not so converted) to
         the holder via express courier within five (5) business days after the
         Corporation has received the original Notice


                                      E-15





         of Conversion and shares certificate being so converted. The Notice of
         Conversion and certificate representing the portion of the shares of
         Series E 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.

                  d. No fractional shares of Common Stock shall be issued upon
         conversion of the Series E 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 E 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 (c) above, the Corporation shall
         issue and deliver at such office to such holder of Series E 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 E
         Preferred Stock, and a certificate for any shares of Series E Preferred
         Stock not so converted.

                  f. Upon any conversion of Series E Preferred Stock pursuant to
         this Paragraph 4 the shares of Series E 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
         E 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 E 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 Paragraphs 4 and 5(a) to be given to the holders of
         shares of Series E Preferred Stock shall be deemed effectively given
         (i) on the date delivered, if transmitted by facsimile (with a machine
         generated confirmation) or (ii) five business days after deposit in the
         United States mail, first class, postage prepaid and addressed to each
         holder of record at its address, on the next business day, if sent by a
         recognized international courier (with all costs prepaid), in the
         manner set forth in the Securities Purchase Agreement, with all
         required copies set forth therein.

                  h. Subject to the Exchange Cap (as defined below), each share
         of Series E Preferred Stock which remains outstanding on the second
         anniversary of the Closing Date shall automatically be converted on
         such date into shares of Common Stock.

                  i. The Corporation shall at all times when any shares of
         Series E 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 E Preferred
         Stock.

                                      E-16





                  j. The Corporation shall not be obligated to issue upon
         conversion of the Series E Preferred Stock, in the aggregate, shares of
         Common Stock equal to more than 19.99% of the Common Stock outstanding
         on the date of issuance of the Series E Preferred Stock (such amount to
         be proportionately and equitably adjusted from time to time in the
         event of stock splits, stock dividends, combinations, reverse stock
         splits, reclassification, capital reorganizations and similar events
         relating to the Common Stock) (the "Exchange Cap") if issuance of a
         larger number of shares of Common Stock would constitute a breach of
         the Corporation's obligations under the rules or regulations of The
         Nasdaq Stock Market, Inc. ("Nasdaq") or any other principal securities
         exchange or market upon which the Common Stock is or becomes traded. If
         the conversion of any shares of Series E Preferred Stock would result
         in the issuance of shares of Common Stock which in the aggregate will
         equal or exceed the Exchange Cap, the Corporation shall within sixty
         (60) days from the Closing Date file a proxy statement in order to seek
         approval of the stockholders of the Corporation as required by the
         applicable rules or regulations of Nasdaq for issuances of Common Stock
         in excess of the Exchange Cap. The Corporation shall comply with all
         applicable rules and regulation of the Securities Act of 1933, as
         amended (the "Securities Act"), the Securities Exchange Act of 1934, as
         amended (the "Exchange Act"), and Nasdaq, as applicable, at the expense
         of the Corporation. If the Corporation obtains the approval of
         stockholders as required under the rules or regulations of Nasdaq, the
         Corporation shall be obligated to issue upon conversion of the Series E
         Preferred Stock, in the aggregate, shares of Common Stock in excess of
         the Exchange Cap. If the Corporation does not obtain the approval of
         stockholders as required under the rules or regulations of Nasdaq or
         fails to call the stockholders meeting within the time herein, each
         holder of Series E Preferred Stock shall have the right, at such
         holder's option, to require the Corporation to redeem, subject to the
         terms of Paragraph 4(k) below, all or a portion of such holder's shares
         of Series E Preferred Stock which the Corporation is unable to convert
         (the "Mandatory Redemption"), at a price per share equal to 115% of the
         Liquidation Preference, plus any accrued but unpaid dividends
         ("Mandatory Redemption Price").

                  k. Upon receipt of a Notice of Conversion from a holder of
         Series E Preferred Stock which cannot be fully satisfied, the
         Corporation shall immediately notify via facsimile to such holder of
         Series E Preferred Stock of the Corporation's inability to fully
         satisfy such holder's Notice of Conversion (the "Inability to Fully
         Convert Notice"). The Inability to Fully Convert Notice shall indicate
         the number of shares of Series E Preferred Stock which cannot be
         converted and the Mandatory Redemption Price. Such holder shall notify
         the Corporation within five (5) business days of receipt of the
         Inability to Fully Convert Notice of its election to cause a Mandatory
         Redemption by delivering written notice via facsimile to the
         Corporation ("Notice in Response to Inability to Convert"). If such
         holder shall elect to have its shares redeemed pursuant to Paragraph
         4(j) above, the Corporation shall pay the Mandatory Redemption Price in
         cash to such holder within five (5) business days after the
         Corporation's receipt of the holders Notice in Response to Inability to
         Convert, provided that prior to the Corporation's receipt of the
         holder's Notice in Response to Inability to Convert, the Corporation
         has not delivered a notice to such holder stating that the event or
         condition triggering the Mandatory Redemption has been cured. From and
         after the date of the Mandatory Redemption (unless the Corporation
         shall default 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 E Preferred Stock so redeemed shall cease to
         have any rights as stockholders of the Corporation, except the right to
         receive, without interest, the Mandatory Redemption Price thereof upon
         surrender of certificates representing the shares of Series E Preferred
         Stock, and such shares shall not thereafter be transferred (except with
         the consent of the


                                      E-17





         Corporation) on the books of the Corporation and shall not be deemed
         outstanding for any purpose whatsoever.

                  l. Notwithstanding the foregoing provisions, in no event
         (except with respect to an automatic conversion of the Series E
         Preferred Stock as provided in Paragraph 4(h) above) shall holders of
         Series E Preferred Stock be entitled to convert any shares of Preferred
         Stock to the extent after such conversion, the sum of (1) the number of
         shares of Common Stock beneficially owned by the holders of Series E
         Preferred Stock and their affiliates (other than shares of Common Stock
         which may be deemed beneficially owned through the ownership of the
         unconverted portion of the Series E Preferred Stock and the unexercised
         portion of any Warrants), and (2) the number of shares of Common Stock
         issuable upon the conversion of the Series E Preferred Stock and
         exercise of the Warrants with respect to which the determination of
         this proviso is being made, would result in beneficial ownership by the
         holders and their affiliates of more than 4.99% of the outstanding
         shares of Common Stock. For purposes of the proviso to the immediately
         preceding sentence, beneficial ownership shall be determined in
         accordance with Section 13(d) of the Exchange Act, except as otherwise
         provided in clause (1) of such proviso. The preceding shall not
         interfere with any Series E Preferred Stock holder's right to convert
         the Series E Preferred Stock or exercise the Warrants which in the
         aggregate total more than 4.99% of the outstanding shares of Common
         Stock, over time, as long as no single holder of Series E Preferred
         Stock owns more than 4.99% of the outstanding Common Stock at any given
         time.

5.       REDEMPTION.

                  a. The Corporation may, at the option of the Board of
         Directors, redeem all or a portion of the outstanding shares of the
         Series E Preferred Stock upon five (5) business days prior written
         notice to the holders of the Series E Preferred Stock (the "Redemption
         Notice") at the redemption price set forth in subparagraph (b) below,
         provided, that the closing bid price of the Common Stock is greater
         than $5.00 per share. The Corporation may not serve a Redemption Notice
         unless it has immediately available funds for a minimum of the amount
         it intends to redeem in a bank account controlled by the Corporation.
         The Redemption Notice shall be given in accordance with Paragraph 4(g)
         above. Such notice shall state the date of redemption (the "Redemption
         Date"), the Redemption Price (as hereinafter defined), the number of
         shares of Series E Preferred Stock of such holders to be redeemed (the
         "Redemption Amount") 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. The Redemption Date shall be no
         more than five (5) business days after receipt of written notice from
         the Corporation. If the Corporation fails to pay the Redemption Price
         by the sixth trading day following the Redemption Date, the redemption
         will be declared null and void and the Corporation shall lose its right
         to serve a Redemption Notice in the future. On or after the Redemption
         Date, the holders of shares of Series E Preferred Stock called for
         redemption shall surrender the certificates evidencing the shares

         any purpose whatsoever.

                  d. There shall be no redemption of any shares of Series E

         purpose.

7.       STATUS.

                  In case any outstanding shares of Series E Preferred Stock
         shall be redeemed, the shares so redeemed shall be deemed to be
         permanently canceled and shall not resume the status of authorized but
         unissued shares of Series E Preferred Stock.

8.       RANKING; CHANGES AFFECTING SERIES E.

         any other class or series of stock of the Corporation

         outstanding, the Corporation shall not (i) alter or change any of the
         powers preferences, privileges, or rights of the Series E Preferred
         Stock; or (ii) amend the provisions of this Paragraph 8, in each case,

         the Series E Preferred Stock.
