the balance and re-engage frog to complete services; and

          WHEREAS,   the  parties  have  reached  agreement  on  the  terms  for
satisfaction of the balance due, for payment over time, and for frog to continue
to provide requested services.

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

          1.  Payment  of  Account:  The total  balance of the  account  owed by
Xybernaut to frog, including but not limited to all services,  goods,  expenses,
and products  provided by frog to Xybernaut  from May 18, 2001 through and up to
the date of this  Agreement  is  $506,498.89  (the  "Balance").  frog  agrees to
receive as payment in full of the Balance,  a cash payment of one-third (1/3) of
the  Balance  in the amount of  $168,832.96  (the "Cash  Payment")  and  receive
compensation  for the  remaining  two-thirds  (2/3) of the Balance,  (a total of
$337,665.93) by way of a grant of Xybernaut common stock,  pursuant to the terms
and conditions contained herein.

          2. Cash Payment:  Xybernaut  will make the Cash Payment of $168,832.96
in  installments  pursuant to the following  schedule:  $50,000 paid at the time
this  Agreement  is  executed  and the  remaining  $118,832.96  shall be paid in
increments  of $20,000,  paid  bi-weekly on December 7 and December 21, 2001 and
January 4,  January 18, and February 1 with the Cash Payment paid in full with a
final  $18,832.96  payment on February  15, 2002 (the  "Final  Payment").  After
receipt  by frog of the  $50,000  payment,  the  remaining  balance  on the Cash
Payment will bear simple  interest at the rate of 10% per annum (computed on the
basis of a year of 365 days). This interest will be paid in a single installment
of $1,891.51 no later than February 15, 2002.

          3. Grant of Stock: The remaining  two-thirds (2/3) of the Balance will
be paid in full by a grant  of  shares  of  Xybernaut  common  stock  of a value
equivalent  to  $337,665.93  discounted

share.

          4.  Registration of Shares:  Xybernaut hereby grants to frog piggyback

under the next  registration  statement  filed by Xybernaut  with respect to its
common stock (other than another registration  statement on Form S-4 or Form S-8
or  any  successor   thereto).   Xybernaut  will  advise  frog  about  any  such
registration  statement  and, if frog requests in writing that the shares are to
be included in such registration  statement,  Xybernaut shall use its reasonable
best efforts to cause the registration statement to be declared effective by the
Securities and Exchange  Commission  (the  "Commission").  If Xybernaut does not
file a registration  statement which includes the shares,  Xybernaut will, prior
to ninety (90) days from the date hereof,  file a  registration  statement  with
respect  to the  shares  and  use its  reasonable  best  efforts  to  cause  the
registration  statement to be declared  effective by the  Commission.  Xybernaut
shall be responsible for the compliance of any such registration  statement with
applicable  securities  laws;  provided that frog shall be  responsible  for any
information about frog specifically  required by applicable securities laws. All
fees and expenses  incident to the  registration of the shares shall be borne by
Xybernaut.  If the frog registration  statement is not declared effective within
fifty (50) days after the filing thereof, Xybernaut will increase or recommence,
whichever  may be  applicable  at the  time,  the  bi-weekly  payments  to  frog
identified  in  paragraph 2 of this  Agreement,  by $40,000 bi- weekly until the
remainder  of the  Balance  is  repaid.  In the  event  bi-weekly  payments  are
increased or commenced under this provision such  installments  will bear simple
interest  at the rate of 10% per annum  (computed  on the basis of a year of 365
days).

          5. frog  Services:  Immediately  upon  receipt of the $50,000  payment
referenced in paragraph 1 herein,  frog will commence work under all outstanding
and new  Xybernaut  work orders  pursuant to the terms and  conditions of the CC
Agreement.  Except for those terms expressly  amended herein,  the parties agree
that the CC  Agreement  remains in full  force and  effect and is not  otherwise
merged or amended by this Agreement.

          6. frog Release:  Provided  Xybernaut is not in breach under the terms
of this Agreement, frog shall forebear and suspend any legal, equitable or other
action against Xybernaut for collection of the Balance.  Upon receipt by frog of
the Final Payment and the grant, registration of shares pursuant to paragraphs 3
and  4  herein,  frog  shall  release  Xybernaut,  its  subsidiaries,  officers,
directors,  employees,  agents,  successors and assigns from any and all claims,
