FOR VALUE  RECEIVED,  the  undersigned,  Kronos Advanced  Technologies,  Inc., a
Nevada  corporation,  and Kronos Air Technologies,  Inc., a Nevada  corporation,
promise to pay to the order of FKA  Distributing  Co.  d/b/a  HoMedics,  Inc., a
Michigan  corporation  ("Lender"),  at the  office of the Lender in the State of
Michigan, Two Million Four Hundred and 00/100 ($2,400,000.00)  Dollars (U.S.) as
set forth herein. Interest on the unpaid principal balance from the date of this
Note  shall  accrue  at the rate of 6% per  annum  until  maturity,  whether  by
acceleration or otherwise, or until Default, as later defined, and after that at
a default  rate equal to the rate of interest  otherwise  prevailing  under this
Note plus 3% per annum (but in no event in excess of the maximum rate  permitted
by  law).  Interest  shall  be  calculated  for the  actual  number  of days the
principal is  outstanding  on the basis of a 365/366 day year. No payments shall
be required  under this Note during the first twelve (12)  months,  but interest
shall  accrue  during  such  twelve  (12) month  period  and become  part of the
principal  balance of the Note and be  included  as  principal  for  purposes of
calculating  amortization.  Payments of principal and accrued interest due under
this  Note  shall be  payable  in  sixteen  (16)  equal  quarterly  installments
beginning on August 1, 2004 and  continuing  on the first day of each  November,
February,  May and August.  The entire remaining unpaid balance of principal and
accrued interest shall be payable on the fifth (5th) anniversary of this Note. A
late  installment  charge equal to 5% of each late installment may be charged on
any installment payment not received by the Lender within 10 calendar days after
the  installment  due date,  but  acceptance of payment of this charge shall not
waive any Default under this Note.

This  Note  and  any  other  indebtedness  and  liabilities  of any  kind of the
undersigned to the Lender, and any and all modifications, renewals or extensions
of it, whether joint or several,  contingent or absolute,  now existing or later
arising, and however evidenced (collectively  "Indebtedness") are secured by and
the Lender is granted a security  interest in all  property  of the  undersigned
from time to time in the  possession of the Lender and by any other  collateral,
rights and properties described in each and every mortgage,  security agreement,
pledge, assignment and other security or collateral agreement which has been, or
will at any time(s) later be,  executed by the undersigned to or for the benefit
of the Lender (collectively "Collateral").

(the "Master Loan Agreement")),  by maturity,  acceleration or otherwise; or (b)
fail to comply (after the  expiration of the 30 day grace period as set forth in

with this Note or any of the  Indebtedness  shall be  discovered  to be false or
misleading in any material respect;  (e) or if there is any termination,  notice
of  termination,  or breach of any guaranty,  pledge,  collateral  assignment or
subordination agreement relating to all or any part of the Indebtedness;  or (f)
if there is any failure by the undersigned to pay when due (after the expiration
of the 30 day grace period as set forth in the Master Loan Agreement) any of its
indebtedness  in  excess  of  $25,000  (other  than  to  the  Lender)  or in the
observance  or  performance  of any term,  covenant or condition in any document
evidencing,  securing or relating to such indebtedness; or (g) if there is filed
or issued a levy or writ of  attachment  or  garnishment  or other like judicial
process upon the undersigned or any of the Collateral, then the Lender, upon the
occurrence of any of these events (each a "Default"),  may at its option declare
any or all of the  Indebtedness  to be  immediately  due  and  payable,  sell or
liquidate all or any portion of the Collateral, set off against the Indebtedness
any  amounts  owing by the Lender to the  undersigned,  charge  interest  at the
default rate provided in the document  evidencing the relevant  Indebtedness and
exercise any one or more of the rights and remedies granted to the Lender by any
agreement with the undersigned or given to it under applicable law. All payments
