ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

         On April 7, 2000, the  transactions  contemplated  by the Agreement and
Plan of Merger (the "Merger Agreement") among Xybernaut Corporation,  a Delaware
corporation   ("Xybernaut"),   Selfware  Acquisition  Corporation,   a  Virginia
corporation and a wholly owned subsidiary of Xybernaut ("Subsidiary"), Selfware,
Inc., a Virginia corporation ("Selfware"),  and certain shareholders of Selfware
were consummated.

         Pursuant to the Merger Agreement, among other things, Subsidiary merged
with and into Selfware (the "Merger"), with Selfware continuing as the surviving
corporation  and a  wholly-owned  subsidiary  of  Xybernaut.  As a result of the
Merger, the holders of each share of Selfware common stock, par value $0.005 per
share (the "Selfware  Shares"),  outstanding at the effective time of the Merger
(the  "Selfware  Stockholders")  received  0.1323 shares of  Xybernaut's  common
stock,  par value  $0.01 per share  (the  "Common  Stock"),  and cash in lieu of
fractional  shares.  At the  effective  time of the Merger,  3,245,307  Selfware
Shares were issued and outstanding.

         The shares of Common  Stock to be issued to the  Selfware  Stockholders
and payment for fractional  share interest in Common Stock was, or will be, made
as follows:  (i) 60% of the Common  Stock  which each  Selfware  Stockholder  is
entitled to receive,  rounded to the nearest whole share, was issued on April 7,
2000 (the "Effective Date") and (ii) the remaining 40% of the Common Stock which
each  Selfware  Stockholder  is entitled to receive will be issued on a deferred
basis,  with the date of issuance of such shares of Common  Stock being the 90th
day after the Effective Date.

         The terms of the Merger were  determined  in  arms-length  negotiations
between   Xybernaut  and  Selfware  and  a  fairness  opinion  was  provided  to
Xybernaut's  board of directors by Merrill Lynch.  This opinion covered only the
fairness of the exchange  ratio for the  acquisition  from a financial  point of
view and did not  address the merits of the  decision to merge with  Selfware or
the financial  impact of such merger.  Mr. Jacques  Rebibo,  chairman and CEO of
Selfware,  served on Xybernaut's  board of directors from January 1996 to August
1997.

         Concurrently  with the execution and delivery of the Merger  Agreement,
Xybernaut  and the  Selfware  Stockholders  entered into a  registration  rights
agreement  (the  "Registration  Rights  Agreement").  Under  the  terms  of  the
Registration  Rights Agreement,  Xybernaut has agreed to use its best efforts to
file within 90 days after the Effective Date a  registration  statement with the
Securities  and Exchange  Commission for the  registration  of 25% of the Common
Stock  issued  pursuant to the Merger  (the  "Registrable  Securities")  and any
shares  of  Common  Stock  issuable  upon  any  stock  split,   stock  dividend,
recapitalization or similar event with respect to such Registrable Securities.

         The  description of the Merger  Agreement and the  Registration  Rights
Agreement  in Item 2 of this  Current  Report  on Form 8-K is  qualified  in its
entirety by reference to the actual  Merger  Agreement and  Registration  Rights
Agreement,  respectively, which are attached hereto as exhibits and incorporated
herein by reference.


                                     Page 2

         Prior to consummation of the Merger,  neither  Xybernaut nor Subsidiary
beneficially owned,  directly or indirectly,  any voting securities of Selfware,
apart from any  beneficial  ownership  interest  they may have had from entering
into the Merger Agreement.

ITEM 7. FINANCIAL STATEMENTS, PRO FORMA FINANCIAL INFORMATION AND EXHIBITS.

(a)      Financial Statements of Business Acquired.

                      Not applicable.

(b)      Pro Forma Financial Information.

                UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

         The following  unaudited pro forma combined  financial  statements give
effect to the Merger of Xybernaut and Selfware, on a pooling-of-interests basis.
The  unaudited  pro  forma  combined  financial  statements  are  based  on  the
respective  historical  financial  statements and the notes thereto of Xybernaut
and Selfware, which are incorporated by reference in this Current Report on Form
8-K. The unaudited pro forma combined balance sheet assumes that the Merger took
place on December  31, 1999 and combines  Xybernaut's  December 31, 1999 audited
consolidated  balance sheet with  Selfware's  December 31, 1999 audited  balance
sheet. The unaudited pro forma combined statement of operations assumes that the
Merger  took  place as of  January  1,  1999 and  combines  Xybernaut's  audited
consolidated  statement of operations  for the year ended December 31, 1999 with
Selfware's audited statement of operations for the year ended December 31, 1999.

         The unaudited pro forma combined financial  statements are based on the
estimates and  assumptions  set forth in the notes to such  statements.  The pro
forma  adjustments  made in  connection  with the  development  of the pro forma
information are preliminary and have been made solely for purposes of developing
such pro forma  information for illustrative  purposes  necessary to comply with
the  disclosure  requirements  of the Securities  and Exchange  Commission.  The
unaudited  pro  forma  combined  financial  statements  do  not  purport  to  be
indicative  of the  results of  operations  for future  periods or the  combined
financial position or the results that actually would have been realized had the
entities been a single entity during these periods.

         Xybernaut and Selfware estimate that they will incur direct transaction
costs of approximately $350,000 associated with the Merger which will be charged
to operations in the second  quarter of 2000,  which is the quarter in which the
Merger was  consummated.  There can be no assurance  that Xybernaut and Selfware
will not incur  additional  charges in  subsequent  quarters  to  reflect  costs
associated with the Merger.

NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

NOTE 1. PERIODS COMBINED

         The  Xybernaut  consolidated  balance sheet as of December 31, 1999 has
been combined with the Selfware balance sheet as of December 31, 1999.

         The Xybernaut  consolidated  statement of operations for the year ended
December 31, 1999 has been  combined  with the Selfware  statement of operations
for the year ended December 31, 1999.

NOTE 2. MERGER COSTS

         Xybernaut  and Selfware  estimate  they will incur  direct  transaction
costs of approximately  $350,000 associated with the Merger,  consisting of fees
for investment banking, legal, accounting, and other related charges.

NOTE 3. PRO FORMA NET LOSS PER SHARE

         The  unaudited  pro forma  combined  net loss per common share is based
upon the pro forma  weighted  average  number  of shares of common  stock of the
combined Xybernaut and Selfware entity  outstanding  during 1999,  including the
429,327 shares of Xybernaut  Common Stock issued in exchange for the outstanding
common stock of  Selfware.  Pursuant to the terms of the Merger  agreement,  the
shares of Xybernaut  Common  Stock were issued for an effective  price of $18.97
per share based on the average  market  price of  Xybernaut's  stock  during the
thirty calendar days immediately preceding the date of the Merger.

                          AGREEMENT AND PLAN OF MERGER

                              DATED MARCH 30, 2000
                              --------------------

         The parties to this Agreement and Plan of Merger (this "Agreement") are
Selfware Acquisition Corporation, a Virginia corporation ("Acquisition Sub") and
a wholly-owned subsidiary of Xybernaut Corporation, a Delaware corporation
("Xybernaut"), on the one hand, and Selfware, Inc., a Virginia corporation (the
"Company"), and Jacques Rebibo, Vernon Miskowich and Edward Maddox, each an
individual, as shareholders of the Company (the "Principal Shareholders"), on
the other hand.

                                    RECITALS
                                    --------

         This Agreement contemplates a transaction in which Acquisition Sub will
merge with and into the Company with the result that the Company will continue
as the surviving corporation and the separate existence of Acquisition Sub shall
cease. As a result of the Merger, at the Effective Time (as hereinafter
defined), the outstanding shares of the capital stock of the Company shall be
converted into the right to receive the shares of Xybernaut common stock, par
value $.01 per share, described below.

         The Board of Directors of Acquisition Sub and the Board of Directors of
the Company have each determined that the Merger is in the best interests of
their respective shareholders, and have each duly adopted resolutions approving
this Agreement and the transactions contemplated hereby. In accordance with the
foregoing, Acquisition Sub desires to merge with and into the Company and the
Company desires to merge with Acquisition Sub upon and subject to the terms and
conditions set forth below.

         For federal income tax purposes, it is intended that the Merger (as
defined in Section 1.1) shall qualify as a reorganization within the meaning of
Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code") and
the regulations promulgated thereunder, and that this Agreement shall constitute
a "plan of reorganization" for purposes of the Code.

         For accounting purposes, it is intended that the Merger shall be
accounted for as a pooling of interests transaction under United States
generally accepted accounting principles.

         It is therefore agreed as follows:

                                   AGREEMENTS

1.       THE MERGER.

         1.1 The Merger. Subject to the terms and conditions of this Agreement,
at the Effective Time (as defined in Section 1.3), in accordance with the terms
and conditions of this Agreement and in accordance with the Virginia Stock
Corporation Act (the "VSCA"), Xybernaut and the Principal Shareholders shall
cause Acquisition Sub to be merged with and into the Company (the "Merger").

<PAGE>

         1.2 Effect of the Merger. The Merger shall have the effects set forth
in the VSCA. At the Effective Time the separate existence of Acquisition Sub
shall cease, all the assets, properties, rights, privileges, powers and
franchises of Acquisition Sub shall vest in the Company and all debts,
liabilities and duties of Acquisition Sub shall become the debts, liabilities
and duties of the Company.

         1.3 Consummation of the Merger. The Merger shall become effective upon
the filing with the Secretary of State of the Commonwealth of Virginia of
properly executed articles of merger (the "Articles of Merger") on the Closing
Date (as hereinafter defined). The Merger shall be effective when the Articles
of Merger have been filed. The date and time when the Merger is effective is
referred to as the "Effective Time."

         1.4 Charter; Bylaws; Directors and Officers. The articles of
incorporation of the Company from and after the Effective Time shall be the
articles of incorporation of the Company immediately prior to the Effective Time
unless amended pursuant to the Articles of Merger and thereafter amended in
accordance with the provisions thereof and as provided by the VSCA. The bylaws
of the Company from and after the Effective Time shall be the bylaws of
Acquisition Sub as in effect immediately prior to the Effective Time. The
initial directors and officers of the Company on and after the Effective Time
shall be the directors and officers, respectively, of Acquisition Sub
immediately prior to the Effective Time, in each case until their respective
successors are duly elected and qualified.

         1.5 The Closing. Subject to Section 2.3, the consummation of the Merger
and the other transactions contemplated by this Agreement (the "Closing") shall
take place at such location as shall be mutually acceptable to the parties at
10:00 a.m., local time, within three (3) business days of the satisfaction of
all closing conditions contained herein, but in no event later than April 30,

         1.6 Further Assurances. On and after the Effective Time, each of the

the requesting party may reasonably request to vest, perform or confirm, of
record or otherwise, in the Company, its respective rights, title or interest
in, to or under any of the rights, privileges, powers, franchises, properties or
assets of the Acquisition Sub, or otherwise to evidence or implement the
transactions contemplated by this Agreement.

2.       CONVERSION OF SHARES.

         2.1 Conversion of Shares. By virtue of the Merger and without any
action on the part of the respective shareholders of the Company and Acquisition
Sub, at the Effective Time, all of the outstanding shares (the "Company Shares")
of common stock of the Company, par value $.005 per share (the "Company Common
Stock"), of which 3,074,432 Company Shares are issued and outstanding on the
date hereof and an additional 170,875 Company Shares issuable pursuant to the
exercise of outstanding options will be issued and outstanding at the Effective

the names of the persons set forth on Schedule 2.1 (the "Company Shareholders")
of the disclosure statement, of even date herewith, delivered to Xybernaut by
the Company (the "Disclosure Statement"), shall be converted into the right to
receive shares (the "Xybernaut Shares") of Xybernaut common

                                       3
<PAGE>

stock, par value $.01 per share ("Xybernaut Common Stock"), and cash in lieu of
fractional shares of Xybernaut Common Stock, as follows:

            (a) The number of Xybernaut Shares to be issued to the Company's
shareholders pursuant to the Merger shall be based upon (i) an exchange ratio
that values each Xybernaut Share at $14.139, which exchange ratio shall be
adjusted as set forth below if the Average Market Price (as defined below) of
Xybernaut Common Stock is greater than $18.3807 or less than $9.8973, and (ii) a
Company value equal to $6,265,628, or $1.93 per Company Share, representing one
hundred twenty-five percent (125%) of the Company's Net Sales (as defined below)
for its fiscal year ended December 31, 1999, as set forth in the financial
statements of the Company audited by Robinson, Farmer, Cox Associates for the
year then ended, annexed to Schedule 3.5(a) of the Disclosure Statement.

            (b) At the Effective Time, each outstanding Company Share shall
cease to be outstanding and, subject to Section 2.2 hereof, shall be converted
into the right to receive the number of Xybernaut Shares equal to the Exchange
Ratio, together with cash in lieu of fractional shares of Xybernaut Common
Stock, as described below (the "Merger Consideration"). The Exchange Ratio
(based on 3,245,307 Company Shares, which shall be adjusted for any change in
the number of Company Shares issued and outstanding at the Effective Time) shall
be determined as follows:

                  (i) If the Average Market Price of the Xybernaut Common Stock
is equal to a price that is not more than $18.3807 or less than $9.8973, the
Exchange Ratio shall be equal to 0.1365.

                  (ii) If the Average Market Price of the Xybernaut Common Stock
is more than $18.3807, the Exchange Ratio shall be equal to (x) 0. 1365,
multiplied by (y) $18.3807, divided by (z) the Average Market Price.

                  (iii) If the Average Market Price of the Xybernaut Common
Stock is less than $9.8973, the Exchange Ratio shall be equal to (x) 0.1365,
multiplied by (y) $9.8973, divided by (z) the Average Market Price.

            (c) "Average Market Price" shall mean the average of the closing bid
and asked prices for Xybernaut Common Stock on the NASDAQ Small Cap Market for
the trading days within the period of thirty (30) calendar days immediately
preceding the Closing Date.

            (d) "Net Sales" shall mean revenues as reported in the Company's
Financial Statements (as defined in Section 3.5(a)) for the year ended December
31, 1999 in the amount of $5,012,502.

            (e) From and after the Effective Time, holders of a certificate or
certificates that immediately before the Effective Time represented shares of
Company Common Stock (the "Certificates") shall have no rights in respect
thereof other than as expressly provided herein or by law. Until surrendered in
accordance with the provisions of Section 2.3(b), holders of unsurrendered
Certificates shall have no right to vote or consent with respect to shares of
Xybernaut Common Stock exchangeable therefor.

<PAGE>
         2.2 Stock Options, Warrants, Treasury Shares, Etc. At the Effective
Time, each outstanding stock option, warrant or other right to purchase any
capital stock of the Company, whether or not then exercisable or vested, shall
be canceled, and no capital stock of Xybernaut, cash or other consideration
shall be paid or delivered in exchange therefor. Any shares of the Company
Common Stock held in the treasury of the Company shall be canceled and retired
and no cash, securities or other consideration shall be paid in respect of such
shares.

         2.3 Surrender and Exchange of Shares; Payment of Merger Consideration.


            (a) Exchange Agent. Prior to the Effective Time, Xybernaut or
Acquisition Sub shall designate an exchange agent in the Merger, or designate
itself to act in such capacity (the "Exchange Agent"), to distribute the Merger
Consideration after the Effective Time. Xybernaut or Acquisition Sub shall
deposit or cause to be deposited with the Exchange Agent as of the Effective
Time, for the benefit of the holders of shares of Company Common Stock, for
exchange in accordance with this Section 2.3, certificates of Xybernaut Common
Stock ("Xybernaut Certificates") representing the number of whole shares of
Xybernaut Common Stock issuable pursuant to this Section 2 in exchange for
outstanding shares of Company Common Stock. Such shares of Xybernaut Common
Stock, together with any cash payable in lieu of any fractional shares of
Xybernaut Common Stock, are referred to as the "Exchange Fund."

            (b) Exchange Procedures. As soon as practicable after the Effective
Time, the Exchange Agent shall be instructed to mail to each record holder of a
Certificate or Certificates a form of letter of transmittal (which shall specify
that delivery shall be effected, and risk of loss shall pass, only upon proper
delivery of the Certificates to the Exchange Agent) and instructions for use in
effecting the surrender of the Certificates in exchange for the Merger
Consideration. Subject to the provisions of Section 2.3 hereof with respect to
the issuance of Xybernaut Shares in two tranches, upon surrender to the Exchange
Agent of Certificates, together with such letter of transmittal duly executed
and completed in accordance with the instructions thereon, the holders of such
Certificates shall be entitled to receive in exchange therefor (1) Xybernaut
Certificates representing that number of whole shares of Xybernaut Common Stock
which such holders have the right to receive pursuant to the provisions of this
Section 2, and (2) cash in lieu of any fractional share in accordance with
Section 2.3(d), and such Certificates shall forthwith be cancelled. No interest
shall be paid or accrued on the Merger Consideration. All distributions to
holders of Certificates shall be subject to any applicable federal, state, local
and foreign tax withholding, and such withheld amounts shall be treated for all
purposes of this Agreement as having been paid to the holder of Certificates in
respect of which such deduction and withholding was made.

            (c) Distributions with Respect to Unexchanged Shares. No dividends
or other distributions with respect to Xybernaut Common Stock with a record date
after the Effective Time shall be paid to the holder of any unsurrendered
Certificate with respect to the shares of Xybernaut Common Stock represented
thereby, and no cash payment in lieu of fractional shares shall be paid to any
such holder pursuant to Section 2.3(d), and all such dividends, other
distributions and cash in lieu of fractional shares of Xybernaut Common Stock
shall be paid by Xybernaut to the Exchange Agent and shall be included in the
Exchange Fund, in each case until

Stock representing fractional shares of Xybernaut Common Stock or book-entry
credit of the same shall be issued upon the surrender for exchange of
Certificates, no dividend or distribution of Xybernaut shall relate to such
fractional share interests and such fractional share interests will not entitle
the owner thereof to vote or to have any rights as a stockholder of Xybernaut or
a holder of shares of Xybernaut Common Stock.

                  (2) Notwithstanding any other provision of this Agreement,
each holder of Company Shares exchanged pursuant to the Merger who would
otherwise have been entitled to receive a fraction of a share of Xybernaut
Common Stock (after taking into account all Certificates delivered by such
holder pursuant to this Section 2.3) shall receive, in lieu thereof, cash,
without interest, in an amount equal to the product of (i) such fractional part
of a share of Xybernaut Common Stock multiplied by (ii) the value of such
fractional part of a share of Xybernaut Common Stock determined in accordance
with Section 2.1 hereof.

                  (3) As promptly as practicable after the Second Tranche
Closing Date (as defined in Section 2.3(e)(ii) hereof), the Exchange Agent shall
forward payments to such holders of fractional interests of Xybernaut Common
Stock subject to and in accordance with the terms hereof.

            (e) Issuance of Xybernaut Shares in Two Tranches. Notwithstanding
anything in this Agreement to the contrary, the Xybernaut Shares shall be issued
to the Company Shareholders, and payment for fractional share interests in
Xybernaut Common Stock shall be made to Company Shareholders, as follows:

                     (ii) The remaining 40% of the Xybernaut Shares which each
Company Shareholder is entitled to receive in the Merger (the "Second Tranche")
shall be issued on a deferred basis, with the date of issuance of such Xybernaut
Shares (the "Second Tranche Closing Date") to be the ninetieth (90th) day after
the Effective Time.

                     (iii) Subject to the escrow provisions set forth in Section
2.5, (1) upon the surrender for cancellation of the certificates representing
the Company Shares pursuant to this Section 2.3, the Exchange Agent shall
deliver to the Company Shareholders the certificates representing the First
Tranche of the Xybernaut Shares, rounded to the nearest whole share, in the
respective amounts and to the individuals as set forth on Schedule 2.3 of the

Xybernaut Common Stock on the trading day immediately preceding the Closing

Security Act of 1974 ("ERISA")), and all other material employee benefits
(including, without limitation, any non-qualified plans), bonus, deferred

incorporated (an "ERISA Affiliate"), that would be deemed a "single employer"
within the meaning of Section 4001 of ERISA, for the benefit of any employee or
former employee of the Company (the "Plans"). The Principal Shareholders have

each of the Plans, including all amendments to date.

and the applicable provisions of the Internal Revenue Code of 1986, as amended

from the Internal Revenue Service that it is so qualified and neither the
Principal Shareholders nor the Company know of any facts or circumstances that
would materially adversely affect such qualification. None of the Plans is

or medical benefits (whether or not insured), with respect to any employees or
former employees of the Company beyond their retirement or other termination of
service (other than (i) coverage mandated by applicable law, (ii) death benefits
or retirement benefits under any "employee pension plan," as that term is
defined in Section 3(2) of ERISA, or (iii) benefits the full cost of which is
borne by the current or former employee (or his or her beneficiary).

            (d) With respect to each Plan, neither the Company, the Principal
Shareholders nor any ERISA Affiliate has engaged in a "prohibited transaction"
(as such term is defined in Section 4975 or Section 406 of ERISA) that would
subject the Company, Acquisition Sub or Xybernaut to any taxes, penalties or
other liabilities resulting from prohibited transactions under Section 4975 of
the Code or Section 409 or 502(i) of ERISA.

            (e) The Company has complied with the notice and continuation of
coverage requirements of Section 4980B of the Code and the regulations
thereunder with respect to each plan that is, or was during any taxable year of
the Company for which the statute of limitations on the assessment of federal
income taxes remains open, by consent or otherwise, a group health plan within
the meaning of Section 4980B(g) of ERISA.

            (f) No Plan has incurred an "Accumulated Funding Deficiency" (as
defined in Section 302(a) of ERISA or Section 412(a) of the Code), whether or
not waived.

            (g) Neither the Company nor any ERISA Affiliate has incurred or
would incur a "withdrawal" or "partial withdrawal," as defined in Sections 4203

described below, such shares issued hereunder may not be disposed of for a
period of at least one year (and possibly two years) pursuant to Rule 144. The
Principal Shareholders understand that each must bear the economic risk of the
investment indefinitely because, other than pursuant to the Registration Rights

hypothecated or otherwise disposed of unless subsequently registered under the
Securities Act of 1933 and applicable state securities laws or an exemption from
registration is available. Each Principal Shareholder is a sophisticated
investor who either (i) has such knowledge and experience in financial and
business matters such that he is capable of evaluating the merits and risks of
this

Agreement and the Closing hereunder and shall thereafter continue in full force
and effect until the first anniversary of the Closing Date, and the Company's
and the Principal Shareholders' liability in respect of any breach of any such
representation or warranty shall terminate on the first anniversary of the
Closing Date, except for liability with respect to which notice shall have been
given on or prior to such date to the party against which such claim is asserted
pursuant to Section 9.6, which liability shall remain an obligation of the party
against whom such claim is asserted.

         9.2 Survival of Representations and Warranties of Acquisition Sub and
Xybernaut. The Company has the right to rely fully upon the representations and
warranties of Acquisition Sub and Xybernaut contained in this Agreement or in
any other Transaction Document. All such representations and warranties shall
survive the execution and delivery of this Agreement and the

                                       36
<PAGE>

Closing hereunder and shall thereafter continue in full force and effect until
the first anniversary of the Closing Date and the liability of Acquisition Sub
and of Xybernaut in respect of any breach of any such representation or warranty
shall terminate on the first anniversary of the Closing Date, except for
liability with respect to which notice shall have been given on or prior to such
date to the party against which such claim is asserted pursuant to Section 9.6,
which liability shall remain an obligation of the party against whom such claim
is asserted.

         9.3 Determination of Damages Without Regard to "Materiality" or
"Knowledge" Qualifications.

            (a) Certain representations and warranties contained in this
Agreement and in certain Agreements, documents and instruments executed and
delivered in connection with this agreement include either (or both) a
Materiality Qualification (as defined below) or a Knowledge Qualification (as
defined below). Notwithstanding any such qualification, it is the intention of
the parties that the only purpose of the Materiality Qualifications and the
Knowledge Qualifications is to determine whether the representations and
warranties of Article 3 are true and correct for purposes of Acquisition Sub 's
and Xybernaut's condition to consummate the transactions contemplated at the
Closing. Accordingly, Damages recoverable under this Section 9 shall be
determined as though no Materiality Qualification and no Knowledge Qualification
was contained in or applied with respect to any representation or warranty of
Article 3.

            (b) As used herein:

                  (1) the term "Materiality Qualification" means any term,
expression, word or combination thereof that qualifies a representation,
warranty or other statement made with respect to "materiality," "in all material
respects," or insofar as any misstatement of such representation, warranty or
other statement would result in or reflect a "Material Adverse Effect," or words
or terms of similar import, and

                  (2) the term "Knowledge Qualification" means any term,
expression, word or combination thereof that qualifies a representation,
warranty or other statement made with respect to the "knowledge" of the party
making the representation, warranty or other statement.

         9.4 Limited Indemnification by the Principal Shareholders. The
Principal Shareholders shall indemnify and defend Acquisition Sub and Xybernaut
and each of their respective officers, directors, employees, shareholders,
agents, advisors or representatives (each, a "Xybernaut Indemnitee") against,
and hold each Xybernaut Indemnitee harmless from, any loss, liability,
obligation, deficiency, damage, Tax or expense including, without limitation,
interest, penalties, reasonable attorneys' and consultants' fees and
disbursements (collectively, "Damages"), that any Xybernaut Indemnitee may
suffer or incur based upon, arising out of, relating to or in connection with
any of the following (whether or not in connection with any third party claim):

            (a) any breach of any representation or warranty made by the Company
contained in this Agreement or in any other Company Transaction Document or in
respect of any claim made based upon facts that would constitute any such
breach;

                                       37
<PAGE>

            (b) the Principal Shareholders' or the Company's failure to perform
or to comply with any covenant or condition required to be performed or complied
with by the Principal Shareholders or the Company contained in this Agreement or
in any other Company Transaction Document; or

            (c) any claim arising out of the Real Estate Transfer.

         9.5 Indemnification by Acquisition Sub and Xybernaut. Acquisition Sub
and Xybernaut shall indemnify and defend the Principal Shareholders and their
agents, advisors or representatives (each, a "Shareholder Indemnitee") against,
and hold each Shareholder Indemnitee harmless from, any Damages that the
Shareholder Indemnitee may suffer or incur arising from, related to or in
connection with any of the following:

            (a) any breach of any representation or warranty made by Acquisition
Sub or Xybernaut contained in this Agreement or in any other Xybernaut
Transaction Document or in respect of any claim made based upon facts alleged
that would constitute any such breach; or

            (b) the failure of Acquisition Sub or Xybernaut to perform or to
comply with any covenant or condition required to be performed or complied with
by Acquisition Sub or Xybernaut contained in this Agreement or in any other
Xybernaut Transaction Document.

         9.6 Indemnification Procedures.


            (a) Promptly after notice to an indemnified party of any claim or
the commencement of any Proceeding, including any Proceeding by a third party,
involving any Damages, such indemnified party shall, if a claim for
indemnification in respect thereof is to be made against an indemnifying party
pursuant to this Article 9, give written notice to the indemnifying party of the
commencement of such claim or Proceeding, setting forth in reasonable detail the
nature thereof and the basis upon which such party seeks indemnification
hereunder; provided, however, that the failure of any indemnified party to give
such notice shall not relieve the indemnifying party of its obligations under
such section, except to the extent that the indemnifying party is actually
prejudiced by the failure to give such notice.

            (b) (i) In the case of any such Proceeding by a third party against
an indemnified party, the indemnifying party shall, upon notice as provided
above, assume the defense thereof, with counsel reasonably satisfactory to the
indemnified party, and, after notice from the indemnifying party to the
indemnified party of its assumption of the defense thereof, the indemnifying
party shall not be liable to such indemnified party for any legal or other
expenses subsequently incurred by the indemnified party in connection with the
defense thereof (but the indemnified party shall have the right, but not the
obligation, to participate at its own cost and expense in such defense by
counsel of its own choice) or for any amounts paid or foregone by the
indemnified party as a result of the settlement or compromise thereof (without
the written consent of the indemnifying party).

                  (ii) Anything in Section 9.6(b)(i) notwithstanding, if both
the indemnifying party and the indemnified party are named as parties or subject
to such Proceeding and either such party determines with advice of counsel that
there may be one or more legal defenses available to it that are different from
or additional to those available to the other party

                                       38
<PAGE>

or that a material conflict of interest between such parties may exist in
respect of such Proceeding, then the indemnifying party may decline to assume
the defense on behalf of the indemnified party or the indemnified party may
retain the defense on its own behalf, and, in either such case, after notice to
such effect is duly given hereunder to the other party, the indemnifying party
shall be relieved of its obligation to assume the defense on behalf of the
indemnified party, but shall be required to pay any legal or other expenses
including, without limitation, reasonable attorneys' fees and disbursements,
incurred by the indemnified party in such defense.

            (c) If the indemnifying party assumes the defense of any such
Proceeding, the indemnified party shall cooperate fully with the indemnifying
party and shall appear and give testimony, produce documents and other tangible
evidence, allow the indemnifying party access to the books and records of the
indemnified party and otherwise assist the indemnifying party in conducting such
defense. No indemnifying party shall, without the consent of the indemnified
party, consent to entry of any judgment or enter into any settlement or
compromise which does not include as an unconditional term thereof the giving by
the claimant or plaintiff to such indemnified party of a release from all
liability in respect of such claim or Proceeding. Provided that proper notice is
duly given, if the indemnifying party shall fail promptly and diligently to
assume the defense thereof, then the indemnified party may respond to, contest
and defend against such Proceeding (but the indemnifying party shall have the
right to participate at its own cost and expense in such defense by counsel of
its own choice) and may make in good faith any compromise or settlement with
respect thereto, and recover from the indemnifying party the entire cost and
expense thereof including, without limitation, reasonable attorneys' fees and
disbursements and all amounts paid or foregone as a result of such Proceeding,
or the settlement or compromise thereof. The indemnification required hereunder
shall be made by periodic payments of the amount thereof during the course of
the investigation or defense, as and when bills or invoices are received or
loss, liability, obligation, damage or expense is actually suffered or incurred.

         9.7 Limitations on Indemnification.

            (a) The Principal Shareholders shall have indemnification
obligations pursuant to Section 9.4(a) respecting Damages that result from
breaches of representations or warranties set forth in this Agreement only to
the extent set forth in Section 9.7(c).

            (b) Acquisition Sub and Xybernaut shall have indemnification
obligations pursuant to Section 9.5(a) respecting Damages that result from
breaches of representations or warranties set forth in this Agreement only if
and only to the extent that the aggregate of all Damages resulting from such
breaches shall exceed $100,000.

            (c) Notwithstanding anything to the contrary in this Agreement, in
the event a Xybernaut Indemnitee makes a claim for indemnification pursuant to
this Article 9, such claim shall be made solely against the Escrowed Shares
pursuant to the terms of the Escrow Agreement; provided, however, that if a
claim is made by a Xybernaut Indemnitee on account of Damages arising out of the
fraudulent acts or fraudulent omissions of the Company or any Principal
Shareholder with respect to the matters contemplated by this Agreement, and such
claim is upheld by a court of competent jurisdiction in a non-appealable final
judgment, then the

                                       39
<PAGE>

 Principal Shareholders shall be personally liable for the
full amount of such Damages on a joint and several basis, irrespective of the
party responsible for the fraudulent acts or omissions.

full power and authority (including power of

                                       42
<PAGE>

substitution), in the name of and for and on behalf of each of the Principal
Shareholders, or in its own name as Representative, to take all actions required
or permitted under the Escrow Agreement and in connection with the transactions
contemplated thereby, including the giving and receiving of all accountings,
reports, notices and consents and the signing of all certificates, notices,
instructions and other documents and making all determinations hereunder and
thereunder. The authority conferred hereby shall be an agency coupled with an
interest, and all authority conferred hereby is irrevocable and not subject to
termination by the Principal Shareholders (or any of them), or by operation of
law, whether by the death or incapacity of the Principal Shareholders, or the
occurrence of any other event. If any Principal Shareholder should die or become
incapacitated or if any other such event should occur, any action taken by the
Representative shall be as valid as if such death or incapacity, termination or
other event had not occurred, regardless of whether or not the Representative or
any other party hereto or to any other agreement contemplated hereby shall have
received notice of such death, incapacity, termination or other event. Any
notice given to the Representative shall constitute effective notice to each of
the Principal Shareholders, and any other party to the Escrow Agreement or any
other Person may rely on any notice, consent, election or other communication
received from the Representative as if such notice, consent, election or other
communication had been received from each of the Principal Shareholders. With
respect to all matters relating to the Principal Shareholders arising under the
Escrow Agreement, Xybernaut and the escrow agent under the Escrow Agreement
shall be required to deal only with the Representative, and the decision of the
Representative with respect to any matter shall be binding on all of the
Principal Shareholders. The Representative may rely on any notice, instruction,
certificate or other instrument which it believes to be genuine and to have been
signed or presented by a proper person or persons.

         The Principal Shareholders hereby agree to bear the reasonable charges
of the Representative, including reimbursement for out-of-pocket expenses and
other costs, and such attorneys' fees, expenses and other costs as may be
incurred by the Representative in connection with the administration of the
provisions of the Escrow Agreement and the transactions contemplated thereby.

         The Representative shall have no duties or responsibilities except
those expressly set forth in the Escrow Agreement. The Representative shall be
held harmless by the Principal Shareholders from any liability, loss, claim,
demand or expense (including attorney's fees and expenses) arising out of or in
connection with the performance of its obligations in accordance with the Escrow
Agreement, except for any of the foregoing arising out of the gross negligence
or willful misconduct of the Representative. The foregoing provision shall
survive the resignation or substitution of the Representative or the termination
of this Agreement and/or the Escrow Agreement.

herein shall have the meanings respectively assigned to them in the Merger
Agreement. However, no reference to the Merger Agreement or any other instrument
or document shall be deemed to incorporate any term or provision thereof into
this Agreement unless expressly so provided.

         2. Escrow of Xybernaut Shares.

         (a) Pursuant to Section 2.5 of the Merger Agreement, the Principal
Shareholders have contemporaneously herewith delivered to the Escrow Agent an
aggregate of ___________ Xybernaut Shares (the "Escrowed Shares"), as more
particularly set forth on Schedule 1 annexed hereto, together with stock powers
executed in blank by the respective Principal Shareholders, which Schedule sets
forth the number of Xybernaut Shares deposited into escrow by each Principal
Shareholder and the stock certificate numbers of the Xybernaut Shares so
deposited. The Escrowed Shares shall not include any "Registrable Securities,"
as defined in the Registration Rights Agreement. The parties acknowledge and
agree that, for

<PAGE>

purposes of this Agreement, the value of the Escrowed Shares is $____________ in
the aggregate, or $___________ per Share.

         (b) All actions to be taken  hereunder with respect to or on account of
a  Principal   Shareholder  shall  be  taken  exclusively  by  the  Shareholders
Representative,  who  has  been  appointed  to act on  behalf  of the  Principal
Shareholders in accordance with Section 10.14 of the Merger  Agreement.  Each of
Xybernaut and the Escrow Agent shall be entitled to rely on any notice, consent,
certificate,  affidavit,  statement,  paper, document,  writing or communication
provided to it by the Shareholders Representative as having been duly authorized
and approved by the relevant Principal Shareholder(s).  All references herein to
a Principal Shareholder in his capacity as an indemnifying party shall be deemed
to be, solely for purposes of this  Agreement,  references  to the  Shareholders
Representative, acting on behalf of any such indemnifying party.

         (c) All dividends and distributions, if any, and any proceeds thereon
paid by Xybernaut in respect of the Escrowed Shares and delivered to the Escrow
Agent shall be forwarded to the Principal Shareholders, as applicable, and all
voting rights associated with the Escrowed Shares shall remain with the
Principal Shareholders, and the Escrow Agent shall have no right to vote such
Escrowed Shares.

         3. Release of Escrowed Shares.

         (a) In the event that a Xybernaut Indemnitee, (as defined in the Merger
Agreement) determines that there exists a claim for which it is entitled to be
reimbursed or indemnified pursuant to the Merger Agreement, such Xybernaut
Indemnitee shall be entitled to assert a claim in writing (an "Asserted Claim")
against the Escrowed Shares in respect of each such claim and amount, as the
case may be, by notifying the Shareholders Representative (with a copy of the
notification to the Escrow Agent) in reasonable detail of the basis and amount
of such Asserted Claim. If, within twenty (20) days after the sending of such
notice by the Xybernaut Indemnitee, the Escrow Agent shall not have received
from the Shareholders Representative a written statement disputing all or any
part of such Asserted Claim, then the Escrow Agent shall deliver to a Xybernaut
Indemnitee such number of the Escrowed Shares as may be available and as may be
necessary to pay the amount of such Asserted Claim in full. If, within twenty
(20) days after the sending of such notice by the Xybernaut Indemnitee, the
Xybernaut Indemnitee and the Escrow Agent shall have received from the
Shareholders Representative a written statement disputing all or a portion of
such Asserted Claim, then the Xybernaut Indemnitee may order the Escrow Agent to
deliver to the Xybernaut Indemnitee such number of the Escrowed Shares as may be
available and as may be necessary to pay any portion of such Asserted Claim that
is not disputed, and the Escrow Agent shall promptly follow such instructions.
The Xybernaut Indemnitee shall have the right to notify the indemnifying party
of Asserted Claims at any time and from time to time, subject to the provisions
of the Merger Agreement.

         (b) In the event that the Shareholders Representative disputes all or a
portion of any Asserted Claim within the time and in the manner prescribed in
Section 3(a) hereof, the Escrow Agent shall have the right to act in accordance
with Section 5 hereof and shall not release any disputed Escrowed Shares until
(i) receipt by the Escrow Agent of joint written

                                       2

<PAGE>

instructions from the Xybernaut Indemnitee and the Shareholders Representative,
directing the manner in which payment of such amounts is to be made, or (ii) as
directed by final order of a court of competent jurisdiction which is not
subject to further appeal or other appellate review, together with an opinion of
counsel to the party which successfully sought such order (or if no party sought
such order, then of counsel reasonably acceptable to the Escrow Agent) to the
effect that such order is not appealable.

(c) Subject to the foregoing and all of the other provisions hereof, as soon as
reasonably practical following the first anniversary of the Closing Date (as
defined in the Merger Agreement), the Escrow Agent shall release the Escrowed
Shares then held by it to the Shareholders Representative.

         (d) In the event that a Xybernaut Indemnitee is entitled to direct the
Escrow Agent to deliver to it any Escrowed Shares deposited in Escrow hereunder
(the "Indemnity Shares") on account of an Asserted Claim, the parties hereby
authorize the Escrow Agent to complete the stock powers deposited with such
Indemnity Shares so as to effect the assignment of the Indemnity Shares to the
Xybernaut Indemnitee in accordance with the Principal Shareholders' respective
proportionate ownership of the Escrowed Shares, net of any required tax or other
withholding or deduction, whereupon the Escrow Agent shall deliver the Indemnity
Shares and related stock powers to the Company for reissuance to Xybernaut and
the Principal Shareholders in accordance with the foregoing, and Xybernaut
hereby agrees to take all actions as shall be necessary or appropriate to effect
the foregoing.

         4. Further Assurances. Each of the Shareholders Representative, on the
one hand, and Xybernaut, on the other hand (collectively, the "Beneficiaries"),
agrees to do such further acts and things and to execute and deliver such
statements, assignments, agreements, instruments and other documents, and the
Shareholders Representative agrees to cause the Principal Shareholders to do
such further acts and things and to execute and deliver such statements,
assignments, agreements, instruments and other documents, as the Escrow Agent
from time to time reasonably may request in connection with the administration,
maintenance, enforcement or adjudication of this Agreement in order (a) to give
the Escrow Agent confirmation and assurance of the Escrow Agent's rights,
powers, privileges, remedies and interests under this Agreement and applicable
law, (b) to better enable the Escrow Agent to exercise any such right, power,
privilege, remedy or interest, or (c) to otherwise effectuate the purpose and
the terms and provisions of this Agreement, each in such form and substance as
may be reasonably acceptable to the Escrow Agent.

         5. Conflicting Demands. If conflicting or adverse claims or demands are
made or notices served upon the Escrow Agent with respect to the escrow provided
for herein, the parties agree that the Escrow Agent shall be entitled to refuse
to comply with any such claim or demand and to withhold and stop all further
performance of this escrow so long as such disagreement shall continue. In so
doing, the Escrow Agent shall not be or become liable for damages, losses,
costs, expenses or interest to any Beneficiary or to any Principal Shareholder
or any other person for its failure to comply with such conflicting or adverse
demands. The Escrow Agent shall be entitled to continue to so refrain and refuse
to so act until such conflicting claims or demands shall have been finally
determined by a court of competent jurisdiction or shall have

                                       3
<PAGE>

been settled by agreement of the parties to such controversy, in which case the
Escrow Agent shall be notified thereof in a notice signed by such parties. The
Escrow Agent may also elect to commence an interpleader or other action for
declaratory judgment for the purpose of having the respective rights of the
claimants adjudicated, and may deposit with the court all funds held hereunder
pursuant to this Agreement; and if it so commences and deposits, the Escrow
Agent shall be relieved and discharged from any further duties and obligations
under this Agreement. The Shareholders Representative, on behalf of the
Principal Shareholders, on the one hand, and Xybernaut, on the other hand, agree
to pay one-half of any and all costs, expenses and reasonable attorneys' fees
and expenses incurred by the Escrow Agent in seeking any such judgment.

         6. Consent to Jurisdiction, Etc. The Shareholders Representative, on
behalf of the Principal Shareholders, and Xybernaut hereby covenant and agree
that the Supreme Court of the State of New York for the County of New York or
(in a case involving diversity of citizenship) the United States District Court
for the Southern District of New York shall have personal jurisdiction and
proper venue over any dispute with the Escrow Agent; provided that the foregoing
consent to jurisdiction and venue by the other parties shall not deprive the
Escrow Agent of the right in its discretion to voluntarily commence or
participate in any action, suit or proceeding in any other court having
jurisdiction and venue over the Beneficiaries. Each Beneficiary hereby waives
personal service of any summons, complaint or other process, which may be
delivered by any of the means permitted for notices under Section 12 hereof. In
any action or proceeding involving the Escrow Agent in any jurisdiction, each
Beneficiary waives trial by jury.

         7. Expenses of the Escrow Agent. Each of the Shareholders
Representative, on the one hand, and Xybernaut, on the other hand, agrees to pay
one-half of any and all costs and expenses incurred by the Escrow Agent in
connection with all waivers, releases, discharges, satisfactions, modifications
and amendments of this Agreement, the administration and holding of the Escrowed
Shares, and the enforcement, protection and adjudication of the parties' rights
hereunder by the Escrow Agent, including, without limitation, the disbursements,
expenses and fees of the Escrow Agent itself and those of other attorneys it may
retain, if any.

         8. Reliance on Documents and Experts. The Escrow Agent shall be
entitled to rely upon any notice, consent, certificate, affidavit, statement,
paper, document, writing or communication (which to the extent permitted
hereunder may be by telecopier or telephone) reasonably believed by it to be
genuine and to have been signed, sent or made by the proper person or persons,
and upon opinions and advice of legal counsel (including itself or counsel for
any party hereto), independent public accountants and other experts selected by
the Escrow Agent.

         9. Status of the Escrow Agent, Etc. The Escrow Agent is acting under
this Agreement as a stakeholder only and shall be considered an independent
contractor with respect to each Beneficiary. No term or provision of this
Agreement is intended to create, nor shall any such term or provision be deemed
to have created, any principal-agent, trust, joint venture, partnership,
debtor-creditor or attorney-client relationship between or among the Escrow
Agent and any of the Beneficiaries. This Agreement shall not be deemed to
prohibit or in any way


                                       4

<PAGE>


restrict the Escrow Agent's representation of Xybernaut or any affiliate of
Xybernaut, who may be advised by the Escrow Agent on any and all matters
pertaining to this Agreement and the Escrowed Shares. Xybernaut, for itself and
its affiliates (collectively, "Xybernaut"), hereby waives any conflict of
interest and irrevocably authorizes and directs the Escrow Agent to carry out
the terms and provisions of this Agreement fairly as to all parties, without
regard to any such representation and irrespective of the impact upon any
Xybernaut Affiliate. The Escrow Agent's only duties are those expressly set
forth in this Agreement, and each Beneficiary authorizes the Escrow Agent to
perform those duties in accordance with its usual practices in holding funds of
its own or those of other escrows. The Escrow Agent may exercise or otherwise
enforce any of its rights, powers, privileges, remedies and interests under this
Agreement and applicable law or perform any of its duties under this Agreement
by or through its directors, officers, partners, employees, attorneys, agents or
designees.

         10. Exculpation. The Escrow Agent and its designees, and their
respective directors, officers, partners, employees, attorneys and agents, shall
not incur any liability whatsoever for the taking of any action in accordance
with the terms and provisions of this Agreement, for any mistake or error in
judgment, for compliance with any applicable law or any attachment, order or
other directive of any court or other authority (irrespective of any conflicting
term or provision of this Agreement), or for any act or omission of any other
person engaged by the Escrow Agent in connection with this Agreement (other than
for a person's own acts or omissions breaching a duty owed to the claimant and
amounting to gross negligence or willful misconduct as finally determined
pursuant to applicable law by a governmental authority having jurisdiction); and
each Beneficiary hereby waives any and all claims and actions whatsoever against
the Escrow Agent and its designees, and their respective directors, officers,
partners, employees, attorneys and agents, arising out of or related directly or
indirectly to any and all of the foregoing acts, omissions and circumstances.
Furthermore, the Escrow Agent and its designees, and their respective directors,
officers, partners, employees, attorneys and agents, shall not incur any
liability (other than for a person's own acts or omissions breaching a duty owed
to the claimant and amounting to gross negligence or willful misconduct as
finally determined pursuant to applicable law by a governmental authority having
jurisdiction) for other acts and omissions arising out of or related directly or
indirectly to this Agreement or the Escrowed Shares; and each Beneficiary hereby
expressly waives any and all claims and actions (other than those attributable
to a person's own acts or omissions breaching a duty owed to the claimant and
amounting to gross negligence or willful misconduct as finally determined
pursuant to applicable law by a governmental authority having jurisdiction)
against the Escrow Agent and its designees, and their respective directors,
officers, partners, employees, attorneys and agents, arising out of or related
directly or indirectly to any and all of the foregoing acts, omissions and
circumstances.

         11. Indemnification. The Escrow Agent and its designees, and their
respective directors, officers, partners, employees, attorneys and agents, shall
be indemnified, reimbursed, held harmless and, at the request of the Escrow
Agent, defended, by the Beneficiaries, jointly and severally, from and against
any and all claims, liabilities, losses and expenses (including, without
limitation, the disbursements, expenses and fees of their respective attorneys)
that may be imposed upon, incurred by, or asserted against any of them, arising
out of or related directly

                                       5

<PAGE>

or indirectly to this Agreement or the Escrowed Shares, except such as are
occasioned by the indemnified person's own acts and omissions breaching a duty
owed to the claimant and amounting to gross negligence or willful misconduct as
finally determined pursuant to applicable law by a governmental authority having
jurisdiction.

         12. Notices. Any notice or demand hereunder to or upon either party
hereto required or permitted to be given or made shall be deemed to have been
duly given or made for all purposes if (a) in writing and sent by (i) messenger
or an overnight courier service against receipt, or (ii) certified or registered
mail, postage paid, return receipt requested, or (b) sent by telegram, telecopy,

Ladies and Gentlemen:

         Each of the undersigned has been advised that, as of the date of this
letter, he may be deemed to be an affiliate of Selfware, Inc. a Virginia
corporation (the "Company"), as the term "affiliate" is (i) defined for the
purposes of Rule 144 of the rules and regulations promulgated by the Securities
and Exchange Commission (the "Commission") under the Securities Act of 1933, as
amended, or (ii) used in and for the purposes of Accounting Series Releases Nos.
130 and 135, as amended, promulgated by the Commission. Pursuant to the
Agreement and Plan of Merger, dated as of March ___, 2000 ( the "Merger
Agreement"), among Xybernaut Corporation, a Delaware corporation ("Xybernaut"),
the Company and each of the stockholders of the Company parties thereto
(collectively, the "Principal Shareholders"), the Principal Shareholders

published, or (b) take any action that could otherwise prevent Xybernaut from
accounting for the Merger as a "pooling of interests" for financial accounting
purposes.

part of any of the undersigned that he is an "affiliate" of the Company as
described in the first paragraph of this letter, other than for purposes of this
letter.

Revenue Service by the transferee and that any false statement I have made

Business Days prior to the filing of the Registration Statement or any related
Prospectus or any amendment or supplement thereto (including any document that
would be incorporated therein by reference), the Company shall furnish to the
Holders and to any Special Counsel copies of all such documents proposed to be
filed, which documents (other than those incorporated by reference) will be
subject to the review of such Holders and such Special Counsel. The Company
shall not file the Registration Statement or any such Prospectus or any
amendments or supplements thereto to which the

                                      -3-
<PAGE>

Holders of a majority of the Registrable Securities or any Special Counsel shall
reasonably object in writing within two (2) Business Days of their receipt
thereof.

                  (b) (i) Prepare and file with the Commission such amendments,
including post-effective amendments, to the Registration Statement as may be
necessary to keep the Registration Statement continuously effective as to the
applicable Registrable Securities for the Effectiveness Period; (ii) cause the
related Prospectus to be amended or supplemented by any required Prospectus
supplement, and as so supplemented or amended to be filed pursuant to Rule 424
(or any similar provisions then in force) promulgated under the Securities Act;
(iii) respond as promptly as practicable to any comments received from the
Commission with respect to the Registration Statement or any amendment thereto
and as promptly as practicable provide the Holders true and complete copies of
all correspondence from and to the Commission relating to the Registration
Statement; and (iv) comply in all material respects with the provisions of the
Securities Act and the Exchange Act with respect to the disposition of all
Registrable Securities covered by the Registration Statement during the
applicable period in accordance with the intended methods of disposition by the
Holders thereof set forth in the Registration Statement as so amended or in such
Prospectus as so supplemented.

                  (c) Notify the Holders of Registrable Securities to be sold
and any Special Counsel as promptly as practicable (i)(A) when a Prospectus or
any Prospectus supplement or post-effective amendment to the Registration
Statement is proposed to be filed; (B) when the Commission notifies the Company
whether there will be a "review" of such Registration Statement and whenever the
Commission comments in writing on such Registration Statement and (C) with
respect to the Registration Statement or any post-effective amendment, when the
same has become effective; (ii) of any request by the Commission or any other
Federal or state governmental authority for amendments or supplements to the
Registration Statement or Prospectus or for additional information; (iii) of the
issuance by the Commission of any stop order suspending the effectiveness of the
Registration Statement covering any or all of the Registrable Securities or the
initiation of any Proceedings for that purpose; (iv) of the receipt by the
Company of any notification with respect to the suspension of the qualification
or exemption from qualification of any of the Registrable Securities for sale in
any jurisdiction, or the initiation or threatening of any Proceeding for such
purpose; and (v) of the occurrence of any event that makes any statement made in
the Registration Statement or Prospectus or any document incorporated or deemed
to be incorporated therein by reference untrue in any material respect or that
requires any revisions to the Registration Statement, Prospectus or other
documents so that, in the case of the Registration Statement or the Prospectus,
as the case may be, it will not contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.

                  The Company shall promptly furnish to Special Counsel, without
charge, (i) a copy of any correspondence from the Commission or the Commission's
staff to the Company or its representatives relating to any Registration
Statement and (ii) promptly after the same is prepared and filed with the

                                      -4-
<PAGE>

                  (d) Use its best efforts to avoid the issuance of, or, if
issued, obtain the withdrawal of, (i) any order suspending the effectiveness of
the Registration Statement or (ii) any suspension of the qualification (or
exemption from qualification) of any of the Registrable Securities for sale in
any jurisdiction, at the earliest practicable moment.

                  (e) Furnish to each Holder and any Special Counsel, without
charge, at least one conformed copy of each Registration Statement and each
amendment thereto.

                  (f) Promptly deliver to each Holder and any Special Counsel,
without charge, as many copies of the Registration Statement, Prospectus or
Prospectuses (including each form of prospectus) and each amendment or
supplement thereto as such Persons may reasonably request.

                  (g) Prior to any public offering of Registrable Securities,
use its best efforts to register or qualify or cooperate with the selling
Holders and any Special Counsel in connection with the registration or
qualification (or exemption from such registration or qualification) of such
Registrable Securities for offer and sale under the securities or Blue Sky laws
of such jurisdictions within the United States as any Holder requests in
writing, to keep each such registration or qualification (or exemption
therefrom) effective during the Effectiveness Period and to do any and all other
acts or things necessary to enable the disposition in such jurisdictions of the
Registrable Securities covered by a Registration Statement; provided, however,
that the Company shall not be required to qualify generally to do business in
any jurisdiction where it is not then so qualified or to take any action that
would subject it to general service of process in any such jurisdiction where it
is not then so subject or subject the Company to any material tax in any such
jurisdiction where it is not then so subject.

                  (h) Cooperate with the Holders to facilitate the timely
preparation and delivery of certificates representing Registrable Securities to
be sold pursuant to a Registration Statement, which certificates shall be free
of all restrictive legends, and to enable such Registrable Securities to be in
such denominations and registered in such names as any Holder may request at
least two (2) Business Days prior to any sale of Registrable Securities.

                  (i) Upon the occurrence of any event contemplated by Section
3(c)(v), as promptly as practicable, prepare a supplement or amendment,
including a post-effective amendment, to the Registration Statement or a
supplement to the related Prospectus or any document incorporated or deemed to
be incorporated therein by reference, and file any other required document so
that, as thereafter delivered, neither the Registration Statement nor such
Prospectus will contain an untrue statement of a material fact or omit to state
a material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading.

                  (j) Use its best efforts to cause all Registrable Securities
relating to such Registration Statement to be listed on the Nasdaq and any other
securities exchange, quotation system, market or over-the-counter bulletin
board, if any, on which similar securities issued by the Company are then
listed.

                                      -5-
<PAGE>

                  (k) Comply in all material respects with all applicable rules
and regulations of the Commission and make generally available to its security
holders earning statements satisfying the provisions of Section 11(a) of the
Securities Act and Rule 158 not later than forty-five (45) days after the end of
any 12-month period (or ninety (90) days after the end of any 12-month period if
such period is a fiscal year) commencing on the first day of the first fiscal
quarter of the Company after the effective date of the Registration Statement,
which statement shall conform to the requirements of Rule 158.

                  (l) Require each selling Holder to furnish to the Company
information regarding such Holder and the distribution of such Registrable
Securities as is required by law to be disclosed in the Registration Statement,
and the Company may exclude from such registration the Registrable Securities of
any such Holder who fails to furnish such information within a reasonable time
prior to the filing of each Registration Statement, supplemented Prospectus
and/or amended Registration Statement.

                  If the Registration Statement refers to any Holder by name or
otherwise as the holder of any securities of the Company, then such Holder shall
have the right to require (if such reference to such Holder by name or otherwise
is not required by the Securities Act or any similar federal statute then in
force) the deletion of the reference to such Holder in any amendment or
supplement to the Registration Statement filed or prepared subsequent to the
time that such reference ceases to be required.

                  Each Holder covenants and agrees that (i) it will not sell any
Registrable Securities under the Registration Statement until it has received
copies of the Prospectus as then amended or supplemented as contemplated in
Section 3(f) and notice from the Company that such Registration Statement and
any post-effective amendments thereto have become effective as contemplated by
Section 3(c) and (ii) it and its officers, directors or Affiliates, if any, will
comply with the prospectus delivery requirements of the Securities Act as
applicable to them in connection with sales of Registrable Securities pursuant
to the Registration Statement.

                  Each Holder agrees by its acquisition of such Registrable
Securities that, upon receipt of a notice from the Company of the occurrence of
any event of the kind described in Section 3(c)(ii), 3(c)(iii), 3(c)(iv) or
3(c)(v), such Holder will forthwith discontinue disposition of such Registrable
Securities under the Registration Statement until such Holder's receipt of the
copies of the supplemented Prospectus and/or amended Registration Statement
contemplated by Section 3(i), or until it is advised in writing (the "Advice")
by the Company that the use of the applicable Prospectus may be resumed, and, in
either case, has received copies of any additional or supplemental filings that
are incorporated or deemed to be incorporated by reference in such Prospectus or
Registration Statement.

                  (m) If (i) there is material non-public information regarding
the Company which the Company's Board of Directors (the "Board") reasonably
determines not to be in the Company's best interest to disclose and which the
Company is not otherwise required to disclose, or (ii) there is a significant
business opportunity (including, but not limited to, the acquisition or
disposition of assets (other than in the ordinary course of business) or any
merger, consolidation, tender offer or other similar transaction) available to
the Company which the Board reasonably

                                      -6-
<PAGE>

determines not to be in the Company's best interest to disclose and which the
Company would be required to disclose under the Registration Statement, then the
Company may suspend effectiveness of a registration statement and suspend the
sale of Registrable Securities under a Registration Statement for a period that
the Board, in its sole discretion, determines to be reasonable under the
circumstances (a "Blackout Period").

                  (n) Within three (3) business days after the Registration
Statement which includes the Registrable Securities is ordered effective by the
Commission, the Company shall deliver, and shall cause legal counsel for the
Company to deliver, to the transfer agent for such Registrable Securities (with
copies to the Holders whose Registrable Securities are included in such
Registration Statement) confirmation that the Registration Statement has been
declared effective by the Commission substantially in the form attached hereto
as Exhibit A.

<PAGE>

                  (a) Indemnification by the Company. The Company shall,
notwithstanding any termination of this Agreement, indemnify and hold harmless
each Holder, the officers, directors, agents or employees, if any, of such
Holder and each Person who controls any such Holder (within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act) and the
officers, directors, agents and employees of each such controlling Person, and
the respective successors, assigns, estate and personal representatives of each
of the foregoing, to the fullest extent permitted by applicable law, from and
against any and all claims, losses, damages, liabilities, penalties, judgments,
costs (including, without limitation, costs of investigation) and expenses
(including, without limitation, attorneys' fees and expenses) (collectively,
"Losses"), as incurred, arising out of or relating to any untrue or alleged
untrue statement of a material fact contained in the Registration Statement, any
Prospectus or any form of prospectus or in any amendment or supplement thereto
or in any preliminary prospectus, or arising out of or relating to any omission
or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein (in the case of any Prospectus or form
of prospectus or supplement thereto, in the light of the circumstances under
which they were made) not misleading, except to the extent, but only to the
extent, that such untrue statements or omissions are based upon information
regarding such Holder furnished in writing to the Company by such Holder
expressly for use therein, which information was reasonably relied on by the
Company for use therein. The Company shall notify the Holders promptly of the
institution, threat or assertion of any Proceeding of which the Company is aware
in connection with the transactions contemplated by this Agreement. Such
indemnity shall survive the transfer of the Registrable Securities by the
Holders.

                  (b) Indemnification by Holders. Each Holder shall, severally
and not jointly, indemnify and hold harmless the Company, the directors,
officers, agents and employees, each Person who controls the Company (within the
meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act),
and the directors, officers, agents or employees of such controlling Persons,
and the respective successors, assigns, estate and personal representatives of
each of the foregoing, to the fullest extent permitted by applicable law, from
and against all Losses, as incurred, arising solely out of or based solely upon
any untrue statement of a material fact contained in the Registration Statement,
any Prospectus, or any form of prospectus, or arising solely out of or based
solely upon any omission of a material fact required to be stated therein or
necessary to make the statements therein (in the case of any Prospectus or form
of prospectus or supplement thereto, in the light of the circumstances under
which they were made) not misleading, to the extent, but only to the extent,
that such untrue statement or omission is contained in or omitted from any
information so furnished in writing by such Holder to the Company specifically
for inclusion in the Registration Statement or such Prospectus and that such
information was reasonably relied upon by the Company for use in the
Registration Statement, such Prospectus or such form of prospectus.
Notwithstanding anything to the contrary contained herein, the Holder shall be
liable under this Section 5(b) for only that amount as does not exceed the net
proceeds to such Holder as a result of the sale of Registrable Securities
pursuant to such Registration Statement.

                  (c) Conduct of Indemnification Proceedings. If any Proceeding
shall be brought or asserted against any Person entitled to indemnity hereunder
(an "Indemnified Party"), such Indemnified Party promptly shall notify the
Person from whom indemnity is sought (the

                                      -8-
<PAGE>

"Indemnifying Party) in writing, and the Indemnifying Party shall assume the
defense thereof, including the employment of counsel reasonably satisfactory to
the Indemnified Party and the payment of all fees and expenses incurred in
connection with defense thereof; provided that the failure of any Indemnified
Party to give such notice shall not relieve the Indemnifying Party of its
obligations or liabilities pursuant to this Agreement, except (and only) to the
extent that it shall be finally determined by a court of competent jurisdiction
(which determination is not subject to appeal or further review) that such
failure shall have proximately and materially adversely prejudiced the
Indemnifying Party.

                  An Indemnified Party shall have the right to employ separate
counsel in any such Proceeding and to participate in the defense thereof, but
the fees and expenses of such counsel shall be at the expense of such
Indemnified Party or Parties unless: (1) the Indemnifying Party has agreed in
writing to pay such fees and expenses; or (2) the Indemnifying Party shall have
failed promptly to assume the defense of such Proceeding and to employ counsel
reasonably satisfactory to such Indemnified Party in any such Proceeding; or (3)
the named parties to any such Proceeding (including any impleaded parties)
include both such Indemnified Party and the Indemnifying Party, and such
Indemnified Party shall have been advised by counsel that a conflict of interest
is likely to exist if the same counsel were to represent such Indemnified Party
and the Indemnifying Party (in which case, if such Indemnified Party notifies
the Indemnifying Party in writing that it elects to employ separate counsel at
the expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense thereof and such counsel shall be at the expense of
the Indemnifying Party). The Indemnifying Party shall not be liable for any
settlement of any such Proceeding effected without its written consent, which
consent shall not be unreasonably withheld. No Indemnifying Party shall, without
the prior written consent of the Indemnified Party, effect any settlement of any
pending Proceeding in respect of which any Indemnified Party is a party, unless
such settlement includes an unconditional release of such Indemnified Party from
all liability on claims that are the subject matter of such Proceeding.

                  All fees and expenses of the Indemnified Party (including
reasonable fees and expenses to the extent incurred in connection with
investigating or preparing to defend such Proceeding in a manner not
inconsistent with this Section) shall be paid to the Indemnified Party, as
incurred, within ten (10) Business Days of written notice thereof to the
Indemnifying Party, regardless of whether it is ultimately determined that an
Indemnified Party is not entitled to indemnification hereunder; provided that
the Indemnifying Party may require such Indemnified Party to undertake to
reimburse all such fees and expenses to the extent it is finally judicially
determined that such Indemnified Party is not entitled to indemnification
hereunder.

                  (d) Contribution. If a claim for indemnification under Section
5(a) or 5(b) is unavailable to an Indemnified Party because of a failure or
refusal of a governmental authority to enforce such indemnification in
accordance with its terms (by reason of public policy or otherwise), then each
Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall
contribute to the amount paid or payable by such Indemnified Party as a result
of such Losses, in such proportion as is appropriate to reflect the relative
fault of the Indemnifying Party and Indemnified Party in connection with the
actions, statements or omissions that resulted in such Losses, as well as any
other relevant equitable considerations. The relative fault of such Indemnifying
Party and Indemnified Party shall be determined by reference to, among other
things, whether any action in question, including any untrue or alleged untrue
statement of a material fact or omission or alleged omission of a material fact,
has been taken or made by, or relates to information supplied by, such

                                      -9-
<PAGE>


Indemnifying, Party or Indemnified Party, and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
action, statement or omission. The amount paid or payable by a party as a result
of any Losses shall be deemed to include, subject to the limitations set forth
in Section 5(c), any reasonable attorneys' or other reasonable fees or expenses
incurred by such party in connection with any Proceeding to the extent such
party would have been indemnified for such fees or expenses if the
indemnification provided for in this Section was available to such party in
accordance with its terms. Notwithstanding anything to the contrary contained
herein, the Holder shall be liable or required to contribute under this Section
5(d) for only that amount as does not exceed the net proceeds to such Holder as
a result of the sale of Registrable Securities pursuant to such Registration
Statement.

                  The parties hereto agree that it would not be just and
equitable if contribution pursuant to this Section 5(d) were determined by pro
rata allocation or by any other method of allocation that does not take into
account the equitable considerations referred to in the immediately preceding
paragraph. No Person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any Person who was not guilty of such fraudulent misrepresentation.

                  The indemnity and contribution agreements contained in this
Section are in addition to any liability that the Indemnifying Parties may have
to the Indemnified Parties

6.       Rule 144.
         --------

                  As long as any Holder owns Shares, the Company covenants to
use its best efforts to timely file (or obtain extensions in respect thereof and
file within the applicable grace period) all reports required to be filed by the
Company after the date hereof pursuant to Section 13(a) or 15(d) of the Exchange
Act. As long as any Holder owns Shares, if the Company is not required to file
reports pursuant to Section 13(a) or 15(d) of the Exchange Act, it will prepare
and furnish to the Holders and make publicly available in accordance with Rule
144(c) promulgated under the Securities Act annual and quarterly financial
statements, together with a discussion and analysis of such financial statements
in form and substance substantially similar to those that would otherwise be
required to be included in reports required by Section 13(a) or 15(d) of the
Exchange Act, as well as any other information required thereby, in the time
period that such filings would have been required to have been made under the
Exchange Act. The Company further covenants that it will take such further
action as any Holder may reasonably request, all to the extent required from
time to time to enable such Person to sell Shares without registration under the
Securities Act within the limitation of the exemptions provided by Rule 144
promulgated under the Securities Act.

7.       Miscellaneous.
         -------------

(a) Remedies. In the event of a breach by the Company or by a Holder, of any of
their obligations under this Agreement, each Holder or the Company, as the case
may be, in addition to being entitled to exercise all rights granted by law and
under this Agreement, including recovery of damages, will be entitled to
specific performance of its rights under this Agreement. The Company and each
Holder agree that monetary damages would not provide adequate compensation for
any losses incurred by reason of a breach by it of any of the provisions of this
Agreement and hereby further agrees that, in the event of any action for
specific performance in respect of such breach, it shall waive the defense that
a remedy at law would be adequate.

         (b) Specific Enforcement, Consent to Jurisdiction.
             ---------------------------------------------

                    (i) The Company and the Holders acknowledge and agree that
irreparable damage would occur in the event that any of the provisions of this
Agreement were not performed in accordance with their specific terms or were
otherwise breached. It is accordingly agreed that the parties shall be entitled
to an injunction or injunctions to prevent or cure breaches of the provisions of
this Agreement and to enforce specifically the terms and provisions hereof or
thereof, this being in addition to any other remedy to which any of them may be
entitled by law or equity.

                    (ii) Each of the Company and the Holders (i) hereby
irrevocably submits to the jurisdiction of the United States District Court for
the Southern District of New York and the courts of the State of New York
located in New York county for the purposes of any suit, action or proceeding
arising out of or relating to this Agreement and (ii) hereby waives, and agrees
not to assert in any such suit, action or proceeding, any claim that it is not
personally subject to the jurisdiction of such court, that the suit, action or
proceeding is brought in an inconvenient forum or that the venue of the suit,
action or proceeding is improper. Each of the Company and the Holders consents
to process being served in any such suit, action or proceeding by mailing a copy
thereof to such party at the address in effect for notices to it under this
Agreement and agrees that such service shall constitute good and sufficient
service of process and notice thereof. Nothing in this Section shall affect or
limit any right to serve process in any other manner permitted by law.

                  (c) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, unless the same shall be in writing and signed by the Company
and Holders of not less 51% of the Registrable Securities then owned by all
Holders. Notwithstanding the foregoing, a waiver or consent to depart from the
provisions hereof with respect to a matter that relates exclusively to the
rights of Holders and that does not directly or indirectly affect the rights of
other Holders may be given by Holders of at least a majority of the Registrable
Securities to which such waiver or consent relates; provided, however, that the
provisions of this sentence may not be amended, modified, or supplemented except
in accordance with the provisions of the immediately preceding sentence.

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

Ladies and Gentlemen:

         We are counsel to Xybernaut Corporation, a Delaware corporation (the
"COMPANY"), and have represented the Company in connection with that certain
Registration Rights Agreement (the "REGISTRATION RIGHTS AGREEMENT") among the
Company and the shareholders of the Company parties thereto (the "HOLDERS"),
dated as of March __, 2000, pursuant to which the Company agreed, among other
things, to register the Registrable Securities (as defined in the Registration
Rights Agreement) under the Securities Act of 1933, as amended (the "1933 ACT").
In connection with the Company's obligations under the Registration Rights
Agreement, on ________________, 2000, the Company filed a Registration Statement
on Form ___ (File No. ___-________) (the "REGISTRATION STATEMENT") with the
Securities and Exchange Commission (the "SEC") relating to the resale of the
Registrable Securities which names each of the present Holders as a selling
stockholder thereunder.

         In connection with the foregoing, we advise you that a member of the
SEC's staff has advised us by telephone that the SEC has entered an order
declaring the Registration Statement effective under the 1933 Act at [ENTER TIME
OF EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge,
after telephonic inquiry of a member of the SEC's staff, that any stop order
suspending its effectiveness has been issued or that any proceedings for that
purpose are pending before, or threatened by, the SEC and, accordingly, the
Registrable Securities are available for resale under the 1933 Act in the manner
specified in, and pursuant to the terms of the Registration Statement.

                                                              Very truly yours,

Agreement, which shall remain in full force and effect. Since it is the desire
and intent of the parties that the provisions of this Agreement be enforced to

3.       Registration Procedures.

                  In connection with the Company's registration obligations
hereunder, the Company shall:

                  (a) Use its best efforts to prepare and file with the
Commission, on or prior to the Filing Date, a Registration Statement on Form S-3
(or if the Company is not then eligible to register for resale the Registrable
Securities on Form S-3 such registration shall be on another appropriate form in
accordance herewith) in accordance with the method or methods of distribution
thereof as specified by the Holders (except if otherwise directed by the
Holders), and cause the Registration Statement to become effective and remain
effective as provided herein; provided, however, that not less than three (3)
Business Days prior to the filing of the Registration Statement or any related
Prospectus or any amendment or supplement thereto (including any document that
would be incorporated therein by reference), the Company shall furnish to the
Holders and to any Special Counsel copies of all such documents proposed to be
filed, which documents (other than those incorporated by reference) will be
subject to the review of such Holders and such Special Counsel. The Company
shall not file the Registration Statement or any such Prospectus or any
amendments or supplements thereto to which the

                                      -3-
<PAGE>

Holders of a majority of the Registrable Securities or any Special Counsel shall
reasonably object in writing within two (2) Business Days of their receipt
thereof.

                  (b) (i) Prepare and file with the Commission such amendments,
including post-effective amendments, to the Registration Statement as may be
necessary to keep the Registration Statement continuously effective as to the
applicable Registrable Securities for the Effectiveness Period; (ii) cause the
related Prospectus to be amended or supplemented by any required Prospectus
supplement, and as so supplemented or amended to be filed pursuant to Rule 424
(or any similar provisions then in force) promulgated under the Securities Act;
(iii) respond as promptly as practicable to any comments received from the
Commission with respect to the Registration Statement or any amendment thereto
and as promptly as practicable provide the Holders true and complete copies of
all correspondence from and to the Commission relating to the Registration
Statement; and (iv) comply in all material respects with the provisions of the
Securities Act and the Exchange Act with respect to the disposition of all
Registrable Securities covered by the Registration Statement during the
applicable period in accordance with the intended methods of disposition by the
Holders thereof set forth in the Registration Statement as so amended or in such
Prospectus as so supplemented.

                  (c) Notify the Holders of Registrable Securities to be sold
and any Special Counsel as promptly as practicable (i)(A) when a Prospectus or
any Prospectus supplement or post-effective amendment to the Registration
Statement is proposed to be filed; (B) when the Commission notifies the Company
whether there will be a "review" of such Registration Statement and whenever the
Commission comments in writing on such Registration Statement and (C) with
respect to the Registration Statement or any post-effective amendment, when the
same has become effective; (ii) of any request by the Commission or any other
Federal or state governmental authority for amendments or supplements to the
Registration Statement or Prospectus or for additional information; (iii) of the
issuance by the Commission of any stop order suspending the effectiveness of the
Registration Statement covering any or all of the Registrable Securities or the
initiation of any Proceedings for that purpose; (iv) of the receipt by the
Company of any notification with respect to the suspension of the qualification
or exemption from qualification of any of the Registrable Securities for sale in
any jurisdiction, or the initiation or threatening of any Proceeding for such
purpose; and (v) of the occurrence of any event that makes any statement made in
the Registration Statement or Prospectus or any document incorporated or deemed
to be incorporated therein by reference untrue in any material respect or that
requires any revisions to the Registration Statement, Prospectus or other
documents so that, in the case of the Registration Statement or the Prospectus,
as the case may be, it will not contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.

                  The Company shall promptly furnish to Special Counsel, without
charge, (i) a copy of any correspondence from the Commission or the Commission's
staff to the Company or its representatives relating to any Registration
Statement and (ii) promptly after the same is prepared and filed with the
Commission, a copy of any written response to the correspondence received from
the Commission.

                                      -4-
<PAGE>

                  (d) Use its best efforts to avoid the issuance of, or, if
issued, obtain the withdrawal of, (i) any order suspending the effectiveness of
the Registration Statement or (ii) any suspension of the qualification (or
exemption from qualification) of any of the Registrable Securities for sale in
any jurisdiction, at the earliest practicable moment.

                  (e) Furnish to each Holder and any Special Counsel, without
charge, at least one conformed copy of each Registration Statement and each
amendment thereto.

                  (f) Promptly deliver to each Holder and any Special Counsel,
without charge, as many copies of the Registration Statement, Prospectus or
Prospectuses (including each form of prospectus) and each amendment or
supplement thereto as such Persons may reasonably request.

                  (g) Prior to any public offering of Registrable Securities,
use its best efforts to register or qualify or cooperate with the selling
Holders and any Special Counsel in connection with the registration or
qualification (or exemption from such registration or qualification) of such
Registrable Securities for offer and sale under the securities or Blue Sky laws
of such jurisdictions within the United States as any Holder requests in
writing, to keep each such registration or qualification (or exemption
therefrom) effective during the Effectiveness Period and to do any and all other
acts or things necessary to enable the disposition in such jurisdictions of the
Registrable Securities covered by a Registration Statement; provided, however,
that the Company shall not be required to qualify generally to do business in
any jurisdiction where it is not then so qualified or to take any action that
would subject it to general service of process in any such jurisdiction where it
is not then so subject or subject the Company to any material tax in any such
jurisdiction where it is not then so subject.

                  (h) Cooperate with the Holders to facilitate the timely
preparation and delivery of certificates representing Registrable Securities to
be sold pursuant to a Registration Statement, which certificates shall be free
of all restrictive legends, and to enable such Registrable Securities to be in
such denominations and registered in such names as any Holder may request at
least two (2) Business Days prior to any sale of Registrable Securities.

                  (i) Upon the occurrence of any event contemplated by Section
3(c)(v), as promptly as practicable, prepare a supplement or amendment,
including a post-effective amendment, to the Registration Statement or a
supplement to the related Prospectus or any document incorporated or deemed to
be incorporated therein by reference, and file any other required document so
that, as thereafter delivered, neither the Registration Statement nor such
Prospectus will contain an untrue statement of a material fact or omit to state
a material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading.

                  (j) Use its best efforts to cause all Registrable Securities
relating to such Registration Statement to be listed on the Nasdaq and any other
securities exchange, quotation system, market or over-the-counter bulletin
board, if any, on which similar securities issued by the Company are then
listed.

                                      -5-
<PAGE>

                  (k) Comply in all material respects with all applicable rules
and regulations of the Commission and make generally available to its security
holders earning statements satisfying the provisions of Section 11(a) of the
Securities Act and Rule 158 not later than forty-five (45) days after the end of
any 12-month period (or ninety (90) days after the end of any 12-month period if
such period is a fiscal year) commencing on the first day of the first fiscal
quarter of the Company after the effective date of the Registration Statement,
which statement shall conform to the requirements of Rule 158.

                  (l) Require each selling Holder to furnish to the Company
information regarding such Holder and the distribution of such Registrable
Securities as is required by law to be disclosed in the Registration Statement,
and the Company may exclude from such registration the Registrable Securities of
any such Holder who fails to furnish such information within a reasonable time
prior to the filing of each Registration Statement, supplemented Prospectus
and/or amended Registration Statement.

                  If the Registration Statement refers to any Holder by name or
otherwise as the holder of any securities of the Company, then such Holder shall
have the right to require (if such reference to such Holder by name or otherwise
is not required by the Securities Act or any similar federal statute then in
force) the deletion of the reference to such Holder in any amendment or
supplement to the Registration Statement filed or prepared subsequent to the
time that such reference ceases to be required.

                  Each Holder covenants and agrees that (i) it will not sell any
Registrable Securities under the Registration Statement until it has received
copies of the Prospectus as then amended or supplemented as contemplated in
Section 3(f) and notice from the Company that such Registration Statement and
any post-effective amendments thereto have become effective as contemplated by
Section 3(c) and (ii) it and its officers, directors or Affiliates, if any, will
comply with the prospectus delivery requirements of the Securities Act as
applicable to them in connection with sales of Registrable Securities pursuant
to the Registration Statement.

                  Each Holder agrees by its acquisition of such Registrable
Securities that, upon receipt of a notice from the Company of the occurrence of
any event of the kind described in Section 3(c)(ii), 3(c)(iii), 3(c)(iv) or
3(c)(v), such Holder will forthwith discontinue disposition of such Registrable
Securities under the Registration Statement until such Holder's receipt of the
copies of the supplemented Prospectus and/or amended Registration Statement
contemplated by Section 3(i), or until it is advised in writing (the "Advice")
by the Company that the use of the applicable Prospectus may be resumed, and, in
either case, has received copies of any additional or supplemental filings that
are incorporated or deemed to be incorporated by reference in such Prospectus or
Registration Statement.

                  (m) If (i) there is material non-public information regarding
the Company which the Company's Board of Directors (the "Board") reasonably
determines not to be in the Company's best interest to disclose and which the
Company is not otherwise required to disclose, or (ii) there is a significant
business opportunity (including, but not limited to, the acquisition or
disposition of assets (other than in the ordinary course of business) or any
merger, consolidation, tender offer or other similar transaction) available to
the Company which the Board reasonably

                                      -6-
<PAGE>

determines not to be in the Company's best interest to disclose and which the
Company would be required to disclose under the Registration Statement, then the
Company may suspend effectiveness of a registration statement and suspend the
sale of Registrable Securities under a Registration Statement for a period that
the Board, in its sole discretion, determines to be reasonable under the
circumstances (a "Blackout Period").

                  (n) Within three (3) business days after the Registration
Statement which includes the Registrable Securities is ordered effective by the
Commission, the Company shall deliver, and shall cause legal counsel for the
Company to deliver, to the transfer agent for such Registrable Securities (with
copies to the Holders whose Registrable Securities are included in such
Registration Statement) confirmation that the Registration Statement has been
declared effective by the Commission substantially in the form attached hereto
as Exhibit A.

4.       Registration Expenses
         ---------------------

                  All fees and expenses incident to the registration of the
Registrable Securities shall be borne by the Company, other than (x) fees and

Holders in connection with Blue Sky qualifications of the Registrable Securities
and determination of the eligibility of the Registrable Securities for

Securities are required hereunder to be listed, and (B) with respect to filings
required to be made with the Commission; (ii) printing expenses (including,
without limitation, expenses of printing certificates for Registrable Securities
and of printing prospectuses if the printing of prospectuses is requested by the
holders of a majority of the Registrable Securities included in the Registration
Statement), (iii) messenger, telephone and delivery expenses, (iv) fees and
disbursements of counsel for the Company and (v) fees and expenses of all other

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

                                      -7-
<PAGE>

                  (a) Indemnification by the Company. The Company shall,
notwithstanding any termination of this Agreement, indemnify and hold harmless
each Holder, the officers, directors, agents or employees, if any, of such
Holder and each Person who controls any such Holder (within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act) and the
officers, directors, agents and employees of each such controlling Person, and
the respective successors, assigns, estate and personal representatives of each
of the foregoing, to the fullest extent permitted by applicable law, from and
against any and all claims, losses, damages, liabilities, penalties, judgments,
costs (including, without limitation, costs of investigation) and expenses
(including, without limitation, attorneys' fees and expenses) (collectively,
"Losses"), as incurred, arising out of or relating to any untrue or alleged
untrue statement of a material fact contained in the Registration Statement, any
Prospectus or any form of prospectus or in any amendment or supplement thereto
or in any preliminary prospectus, or arising out of or relating to any omission
or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein (in the case of any Prospectus or form
of prospectus or supplement thereto, in the light of the circumstances under
which they were made) not misleading, except to the extent, but only to the
extent, that such untrue statements or omissions are based upon information
regarding such Holder furnished in writing to the Company by such Holder
expressly for use therein, which information was reasonably relied on by the
Company for use therein. The Company shall notify the Holders promptly of the
institution, threat or assertion of any Proceeding of which the Company is aware
in connection with the transactions contemplated by this Agreement. Such
indemnity shall survive the transfer of the Registrable Securities by the
Holders.

                  (b) Indemnification by Holders. Each Holder shall, severally
and not jointly, indemnify and hold harmless the Company, the directors,
officers, agents and employees, each Person who controls the Company (within the
meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act),
and the directors, officers, agents or employees of such controlling Persons,
and the respective successors, assigns, estate and personal representatives of
each of the foregoing, to the fullest extent permitted by applicable law, from
and against all Losses, as incurred, arising solely out of or based solely upon
any untrue statement of a material fact contained in the Registration Statement,
any Prospectus, or any form of prospectus, or arising solely out of or based
solely upon any omission of a material fact required to be stated therein or
necessary to make the statements therein (in the case of any Prospectus or form
of prospectus or supplement thereto, in the light of the circumstances under
which they were made) not misleading, to the extent, but only to the extent,
that such untrue statement or omission is contained in or omitted from any
information so furnished in writing by such Holder to the Company specifically
for inclusion in the Registration Statement or such Prospectus and that such
information was reasonably relied upon by the Company for use in the
Registration Statement, such Prospectus or such form of prospectus.
Notwithstanding anything to the contrary contained herein, the Holder shall be
liable under this Section 5(b) for only that amount as does not exceed the net
proceeds to such Holder as a result of the sale of Registrable Securities
pursuant to such Registration Statement.

                  (c) Conduct of Indemnification Proceedings. If any Proceeding
shall be brought or asserted against any Person entitled to indemnity hereunder
(an "Indemnified Party"), such Indemnified Party promptly shall notify the
Person from whom indemnity is sought (the

                                      -8-
<PAGE>

"Indemnifying Party) in writing, and the Indemnifying Party shall assume the
defense thereof, including the employment of counsel reasonably satisfactory to
the Indemnified Party and the payment of all fees and expenses incurred in
connection with defense thereof; provided that the failure of any Indemnified
Party to give such notice shall not relieve the Indemnifying Party of its
obligations or liabilities pursuant to this Agreement, except (and only) to the
extent that it shall be finally determined by a court of competent jurisdiction
(which determination is not subject to appeal or further review) that such
failure shall have proximately and materially adversely prejudiced the
Indemnifying Party.

                  An Indemnified Party shall have the right to employ separate
counsel in any such Proceeding and to participate in the defense thereof, but
the fees and expenses of such counsel shall be at the expense of such
Indemnified Party or Parties unless: (1) the Indemnifying Party has agreed in
writing to pay such fees and expenses; or (2) the Indemnifying Party shall have
failed promptly to assume the defense of such Proceeding and to employ counsel
reasonably satisfactory to such Indemnified Party in any such Proceeding; or (3)
the named parties to any such Proceeding (including any impleaded parties)
include both such Indemnified Party and the Indemnifying Party, and such
Indemnified Party shall have been advised by counsel that a conflict of interest
is likely to exist if the same counsel were to represent such Indemnified Party
and the Indemnifying Party (in which case, if such Indemnified Party notifies
the Indemnifying Party in writing that it elects to employ separate counsel at
the expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense thereof and such counsel shall be at the expense of
the Indemnifying Party). The Indemnifying Party shall not be liable for any
settlement of any such Proceeding effected without its written consent, which
consent shall not be unreasonably withheld. No Indemnifying Party shall, without
the prior written consent of the Indemnified Party, effect any settlement of any
pending Proceeding in respect of which any Indemnified Party is a party, unless
such settlement includes an unconditional release of such Indemnified Party from
all liability on claims that are the subject matter of such Proceeding.

                  All fees and expenses of the Indemnified Party (including
reasonable fees and expenses to the extent incurred in connection with
investigating or preparing to defend such Proceeding in a manner not
inconsistent with this Section) shall be paid to the Indemnified Party, as
incurred, within ten (10) Business Days of written notice thereof to the
Indemnifying Party, regardless of whether it is ultimately determined that an
Indemnified Party is not entitled to indemnification hereunder; provided that
the Indemnifying Party may require such Indemnified Party to undertake to
reimburse all such fees and expenses to the extent it is finally judicially
determined that such Indemnified Party is not entitled to indemnification
hereunder.

                  (d) Contribution. If a claim for indemnification under Section
5(a) or 5(b) is unavailable to an Indemnified Party because of a failure or
refusal of a governmental authority to enforce such indemnification in
accordance with its terms (by reason of public policy or otherwise), then each
Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall
contribute to the amount paid or payable by such Indemnified Party as a result
of such Losses, in such proportion as is appropriate to reflect the relative
fault of the Indemnifying Party and Indemnified Party in connection with the
actions, statements or omissions that resulted in such Losses, as well as any
other relevant equitable considerations. The relative fault of such Indemnifying
Party and Indemnified Party shall be determined by reference to, among other
things, whether any action in question, including any untrue or alleged untrue
statement of a material fact or omission or alleged omission of a material fact,
has been taken or made by, or relates to information supplied by, such

                                      -9-
<PAGE>


Indemnifying, Party or Indemnified Party, and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
action, statement or omission. The amount paid or payable by a party as a result
of any Losses shall be deemed to include, subject to the limitations set forth
in Section 5(c), any reasonable attorneys' or other reasonable fees or expenses
incurred by such party in connection with any Proceeding to the extent such
party would have been indemnified for such fees or expenses if the
indemnification provided for in this Section was available to such party in
accordance with its terms. Notwithstanding anything to the contrary contained
herein, the Holder shall be liable or required to contribute under this Section
5(d) for only that amount as does not exceed the net proceeds to such Holder as
a result of the sale of Registrable Securities pursuant to such Registration
Statement.

                  The parties hereto agree that it would not be just and
equitable if contribution pursuant to this Section 5(d) were determined by pro
rata allocation or by any other method of allocation that does not take into
account the equitable considerations referred to in the immediately preceding
paragraph. No Person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any Person who was not guilty of such fraudulent misrepresentation.

                  The indemnity and contribution agreements contained in this
Section are in addition to any liability that the Indemnifying Parties may have
to the Indemnified Parties

6.       Rule 144.
         --------

                  As long as any Holder owns Shares, the Company covenants to
use its best efforts to timely file (or obtain extensions in respect thereof and
file within the applicable grace period) all reports required to be filed by the
Company after the date hereof pursuant to Section 13(a) or 15(d) of the Exchange
Act. As long as any Holder owns Shares, if the Company is not required to file
reports pursuant to Section 13(a) or 15(d) of the Exchange Act, it will prepare
and furnish to the Holders and make publicly available in accordance with Rule
144(c) promulgated under the Securities Act annual and quarterly financial
statements, together with a discussion and analysis of such financial statements
in form and substance substantially similar to those that would otherwise be
required to be included in reports required by Section 13(a) or 15(d) of the
Exchange Act, as well as any other information required thereby, in the time
period that such filings would have been required to have been made under the
Exchange Act. The Company further covenants that it will take such further
action as any Holder may reasonably request, all to the extent required from
time to time to enable such Person to sell Shares without registration under the
Securities Act within the limitation of the exemptions provided by Rule 144
promulgated under the Securities Act.

7.       Miscellaneous.
         -------------

(a) Remedies. In the event of a breach by the Company or by a Holder, of any of
their obligations under this Agreement, each Holder or the Company, as the case
may be, in addition to being entitled to exercise all rights granted by law and
under this Agreement, including recovery of damages, will be entitled to
specific performance of its rights under this Agreement. The Company and each
Holder agree that monetary damages would not provide adequate compensation for
any losses incurred by reason of a breach by it of any of the provisions of this
Agreement and hereby further agrees that, in the event of any action for
specific performance in respect of such breach, it shall waive the defense that
a remedy at law would be adequate.

         (b) Specific Enforcement, Consent to Jurisdiction.
             ---------------------------------------------

                    (i) The Company and the Holders acknowledge and agree that
irreparable damage would occur in the event that any of the provisions of this
Agreement were not performed in accordance with their specific terms or were
otherwise breached. It is accordingly agreed that the parties shall be entitled
to an injunction or injunctions to prevent or cure breaches of the provisions of
this Agreement and to enforce specifically the terms and provisions hereof or
thereof, this being in addition to any other remedy to which any of them may be
entitled by law or equity.

                    (ii) Each of the Company and the Holders (i) hereby
irrevocably submits to the jurisdiction of the United States District Court for
the Southern District of New York and the courts of the State of New York
located in New York county for the purposes of any suit, action or proceeding
arising out of or relating to this Agreement and (ii) hereby waives, and agrees
not to assert in any such suit, action or proceeding, any claim that it is not
personally subject to the jurisdiction of such court, that the suit, action or
proceeding is brought in an inconvenient forum or that the venue of the suit,
action or proceeding is improper. Each of the Company and the Holders consents
to process being served in any such suit, action or proceeding by mailing a copy
thereof to such party at the address in effect for notices to it under this
Agreement and agrees that such service shall constitute good and sufficient
service of process and notice thereof. Nothing in this Section shall affect or
limit any right to serve process in any other manner permitted by law.

                  (c) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof

Ladies and Gentlemen:

         We are counsel to Xybernaut Corporation, a Delaware corporation (the
"COMPANY"), and have represented the Company in connection with that certain
Registration Rights Agreement (the "REGISTRATION RIGHTS AGREEMENT") among the
Company and the shareholders of the Company parties thereto (the "HOLDERS"),
dated as of March __, 2000, pursuant to which the Company agreed, among other
things, to register the Registrable Securities (as defined in the Registration
Rights Agreement) under the Securities Act of 1933, as amended (the "1933 ACT").
In connection with the Company's obligations under the Registration Rights
Agreement, on ________________, 2000, the Company filed a Registration Statement
on Form ___ (File No. ___-________) (the "REGISTRATION STATEMENT") with the
Securities and Exchange Commission (the "SEC") relating to the resale of the
Registrable Securities which names each of the present Holders as a selling
stockholder thereunder.

         In connection with the foregoing, we advise you that a member of the
SEC's staff has advised us by telephone that the SEC has entered an order
declaring the Registration Statement effective under the 1933 Act at [ENTER TIME
OF EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge,
after telephonic inquiry of a member of the SEC's staff, that any stop order
suspending its effectiveness has been issued or that any proceedings for that
purpose are pending before, or threatened by, the SEC and, accordingly, the
Registrable Securities are available for resale under the 1933 Act in the manner
specified in, and pursuant to the terms of the Registration Statement.

                                                              Very truly yours,

XYBERNAUT(R) ADDS ENTERPRISE MANAGEMENT SOLUTIONS WITH
ACQUISITION OF SELFWARE, INC.

EXPANDED SOLUTIONS EXPECTED TO RESULT IN INCREASED REVENUES AND MARKET
PENETRATION

FAIRFAX,  Va., March 30 /PRNewswire/ -- Xybernaut  Corporation (Nasdaq:  XYBR ),
the leader in wearable  computing and  communications  systems,  today announced
that as part of an overall program to provide total solutions for its customers,
it had executed a definitive  merger  agreement  with  Selfware  Inc., a leading
provider  of   enterprise   management   services  and  software  for  projects,
maintenance and work flow.

Selfware's proprietary OPMIST asset management system has been installed in over
200 sites  worldwide at  shipyards,  utilities,  manufacturers,  departments  of
transportation, military bases and railroads. Among other alliances, Selfware is
a Microsoft Certified Solutions Provider, an authorized Lotus Notes Provider, an
Oracle Program Member and a Sun Catalyst Partner.

Current and past  customers  for Selfware in the  aerospace,  defense,  utility,
transportation,  manufacturing  and information  technology  industries  include
DuPont,  Mack Trucks,  the  Northrop-Grumman  Joint STARS program,  U.S.  Postal
Service,  Port  Authority  of New  York and  Departments  of  Transportation  in
Louisiana, Maine, Minnesota, New York, and New Mexico.

Selfware provides  programming  capabilities in a variety of advanced  languages
including  Visual  Basic and Visual  C++,  along  with  database  experience  in
Microsoft  SQL server,  Oracle and  Sybase.  Telecommunication  and  information
technology  for asset  management  are also provided by Selfware for  computers,
hubs,  routers and data lines,  along with asset management  software for linear
referenced assets including roads, railways, utility, and pipelines.  Selfware's
solutions  have been  developed for Windows  95/98,  Windows NT, UNIX and Novell
Netware.

Selfware is a  privately-held  company  that was founded in 1983 and has over 30
full-time  employees at its  headquarters  in Vienna,  Virginia and an office in
Seattle, Washington. For the twelve months ended December 31, 1999, revenues for
Selfware were  approximately  $5.0 million,  gross profit was approximately $2.0
million and net income was  approximately  $0.1 million.  Under the terms of the
definitive  agreement,  the value of Selfware is  determined by a formula with a
maximum  valuation of  approximately  $8.1 million.  If the closing were to take
place  today,  such  formula  would result in  approximately  400,000  shares of
Xybernaut  stock to be  exchanged  for the stock of  Selfware,  for an effective
price  of  $20.23  per  share of  Xybernaut  stock.  The  approval  of  Selfware
shareholders  for the  acquisition  is  expected  by the end of next  week.  The
transaction  is  intended  to be  accounted  for as a pooling  of  interests.  A
fairness  opinion for the  acquisition  was  provided to  Xybernaut by a leading
investment bank.

Edward G. Newman,  president and CEO of Xybernaut,  stated, "A central component
of our  long-term  strategy  is to make  our  wearable  and core  computers  the
centerpiece of solutions for our customers and the  acquisition of Selfware is a
key step in executing that strategy.  Selfware  brings revenues and an expanding
customer base in the very markets that Xybernaut has targeted for growth,  along
with the  capabilities to readily  transfer this experience to new customers and
markets.  By utilizing our channel partners to leverage the solutions offered by
Selfware,  we believe that this acquisition will allow Xybernaut to more rapidly
expand our revenues."

Jacques Rebibo,  chairman and CEO of Selfware,  Inc., added that, "In two years,
Selfware  has expanded its  revenues  over 175% as customers  have  embraced our
value-added  solutions.  By combining Xybernaut's products with our software and
services,  I am  confident  that  we can  accelerate  revenues  of the  combined
Xybernaut/Selfware   entity  by  reaching  new  markets.   Our   employees   and
shareholders have enthusiastically aligned themselves with Xybernaut, because we
believe  strongly  in  Xybernaut's  prospects,   market  leadership  and  strong
intellectual property position." Mr. Rebibo was a member of Xybernaut's board of
directors  from  January  1996 to August 1997 and has been  chairman  and CEO of
Selfware since May 1997.
