                                OCTOBER __, 2004

JERSEY CITY, NEW JERSEY                                            $2,000,000.00

      FOR VALUE RECEIVED, the undersigned, KRONOS ADVANCED TECHNOLOGIES, INC., a
Nevada corporation (the "COMPANY"), promises to pay CORNELL CAPITAL PARTNERS, LP
(the "HOLDER") at 101 Hudson Street,  Suite 3700,  Jersey City, New Jersey 07302
or other  address as the Holder shall  specify in writing,  the principal sum of
TWO  MILLION  (U.S.)  DOLLARS  AND  00/100  ($2,000,000.00)  and will be payable
pursuant to the following terms:

      1. AMOUNT OF NOTE.  The  principal  amount of this  Promissory  Note (this
"NOTE")  shall be funded upon the filing of the  Registration  Statement on Form
SB-2 (the "REGISTRATION STATEMENT"), filed pursuant to the Investor Registration
Statement dated the date hereof,  with the United States Securities and Exchange
Commission  ("SEC").  The face  amount of this Note plus  twelve  percent  (12%)
interest shall be payable in equal weekly installments of Fifty Thousand Dollars
($50,000.00)  plus twelve  percent (12%) interest on the  outstanding  principal
balance  commencing  on the  date  that  is the  earlier  to  occur  of (i)  the
Registration  Statement is declared effective by the SEC (the "EFFECTIVE DATE");
or (ii) twelve (12) weeks from the date hereof.  For purposes of  clarification,
and without limiting the preceding sentence, the repayment of this Note is in no
manner contingent on the Registration  Statement being declared effective by the
SEC, if the Registration Statement is not declared effective by the SEC the face
amount of this Note plus twelve  percent (12%) interest shall be due and payable
three hundred and sixty five  calendar  days (365) from the date hereof.  In the
event the Registration  Statement is declared  effective,  the Company shall use
the net proceeds to be received by the Company under that certain Standby Equity
Distribution  Agreement (the "STANDBY EQUITY  DISTRIBUTION  AGREEMENT") dated as
October _____, 2004 towards the repayment of the obligations due under this Note
in accordance with this Section 1; provided,  however,  and without limiting the
foregoing,  all amounts due under this Note shall be paid in full three  hundred
sixty five (365) calendar days from the Effective  Date,  unless an extension is
mutually agreed to by the parties in writing.  Failure to pay the obligations in
full under this Note within said  applicable  period shall result in an event of
default  and Holder  shall have the right to see any  remedies  available  to it
under  this Note or at law.  The  Company  hereby  agrees to escrow  forty  (40)
requests for advances under the Standby Equity Distribution Agreement, which are
deemed to be advances under such Standby Equity  Distribution  Agreement,  in an
amount not less an FIFTYTHOUSAND  DOLLARS ($50,000.00) PLUS TWELVE PERCENT (12%)
INTEREST  ON THE  OUTSTANDING  PRINCIPAL  BALANCE  (individually  referred to as
"ADVANCE  NOTICE"  collectively  referred  to  "Advance  Notices")  and,  on the
Effective Date,  _______ Million  (_______) shares of the Company's Common Stock
as required under Section 2.2(d) of the Standby  Equity  Distribution  Agreement
(the  "ESCROWED  SHARES").  The Escrowed  Shares are only an  estimation  of the
shares of the Company's common stock necessary to repay the principal amount and
interest  due  hereunder.  In the event  that  during  the life of this Note the
Escrowed Shares are  insufficient to repay all amounts due hereunder the Company
shall   immediately   escrow,   pursuant  to  the  irrevocable   transfer  agent
instructions   dated  the  date  hereof   (the   "IRREVOCABLE   TRANSFER   AGENT



INSTRUCTIONS") such number of shares of the Company's common stock sufficient to
repay all amounts due  hereunder.  The Advance  Notices and the Escrowed  Shares
will be held in escrow by the Holder's general counsel David Gonzalez, Esq., who
shall  release  such  requests  to the  Holder  every  seven (7)  calendar  days
commencing on the Effective Date. The Holder may at its sole  discretion  retain
and apply the net proceeds of each advance (after deducting any fees owed to the
Holder  under the terms of the Standby  Equity  Distribution  Agreement)  to the
outstanding  balance of this Note as existing from time to time. If this Note is
not paid in full when due, the outstanding principal owed hereunder shall be due
and payable in full together with  interest  thereon at the rate of  twenty-four
percent (24%) per annum or the highest  permitted by  applicable  law, if lower.
During  the term of this Note the  Company  shall  have the  option to repay the
amounts due hereunder in  immediately  available  funds and withdraw any Advance
Notices yet to be effected.  At the Holder's  option the interest due  hereunder
shall be paid when due either in Common Stock or cash.

      2. WAIVER AND CONSENT.  To the fullest extent  permitted by law and except
as otherwise provided herein, the Company waives demand,  presentment,  protest,
notice of dishonor,  suit against or joinder of any other person,  and all other
requirements necessary to charge or hold the Company liable with respect to this
Note.

      3. COSTS,  INDEMNITIES AND EXPENSES.  In the event of default as described
herein,  the Company agrees to pay all reasonable fees and costs incurred by the
Holder in  collecting  or securing or attempting to collect or secure this Note,
including  reasonable  attorneys'  fees and  expenses,  whether or not involving
litigation,  collecting  upon  any  judgments  and/or  appellate  or  bankruptcy
proceedings.  The Company agrees to pay any documentary stamp taxes,  intangible
taxes  or other  taxes  which  may now or  hereafter  apply to this  Note or any
payment made in respect of this Note,  and the Company  agrees to indemnify  and
hold the Holder harmless from and against any liability, costs, attorneys' fees,
penalties, interest or expenses relating to any such taxes, as and when the same
may be incurred.

      4. EVENT OF  DEFAULT.  Upon an Event of Default (as  defined  below),  the
entire principal  balance and accrued interest  outstanding under this Note, and
all other  obligations of the Company under this Note,  shall be immediately due
and payable  without any action on the part of the Holder,  and the Holder shall
be entitled  to seek and  institute  any and all  remedies  available  to it. No
remedy  conferred under this Note upon the Holder is intended to be exclusive of
any other remedy available to the Holder,  pursuant to the terms of this Note or
otherwise.  No single or partial  exercise by the Holder of any right,  power or
remedy  hereunder  shall  preclude any other or further  exercise  thereof.  The
failure  of the  Holder  to  exercise  any right or  remedy  under  this Note or
otherwise,  or delay in exercising such right or remedy,  shall not operate as a
waiver thereof.  An "EVENT OF DEFAULT" shall be deemed to have occurred upon the
occurrence of any of the  following:  (i) the Company should fail for any reason
or for no reason to make  payment  of the  outstanding  principal  balance  plus
accrued interest  pursuant to this Note within the time prescribed herein or the
Company  fails to satisfy any other  obligation  or  requirement  of the Company
under this Note; or (ii) any proceedings under any bankruptcy laws of the United
States  of  America  or under  any  insolvency,  not  disclosed  to the  Holder,
reorganization,  receivership, readjustment of debt, dissolution, liquidation or
any  similar law or statute of any  jurisdiction  now or  hereinafter  in effect
(whether  in law or at equity) is filed by or against  the Company or for all or
any part of its property.

                                       2


      Upon an Event of  Default  the  Holder  is  entitled,  at its  option,  to
convert,  and sell on the same  day,  at any time and from  time to time,  until
payment in full of this  Note,  all o any part of the  principal  amount of this
Note,  plus  accrued  interest,  into shay:  (the  "CONVERSION  SHARES")  of the
Company's  common stock, par value US$0.001 per share ("COMMON  STOCK"),  at the
price per share (the  "CONVERSION  PRICE") equal to seventy percent (70%) of the
lowest closing bid price of the Company's  Common Stock, as quoted by Bloomberg,
LP, for the thirty (30) trading days immediately preceding the conversion date.

      5.  MAXIMUM  INTEREST  RATE.  In no event  shall  any  agreed to or actual
interest charged, reserved or taken by the Holder as consideration for this Note
exceed the limits  imposed by New  Jersey  law.  In the event that the  interest
provisions  of this  Note  shall  result  at any  time or for any  reason  in an
effective  rate of interest that exceeds the maximum  interest rate permitted by
applicable  law, then without  further  agreement or notice the obligation to be
fulfilled shall be automatically  reduced to such limit and all sums received by
the Holder in excess of those lawfully  collectible as interest shall be applied
against  the  principal  of this  Note  immediately  upon the  Holder's  receipt
thereof,  with the same force and effect as though the Company had  specifically
designated  such extra sums to be so  applied  to  principal  and the Holder had
agreed  to  accept  such  extra  payment(s)  as  a  premium-free  prepayment  or
prepayments.

      6.  CANCELLATION  OF NOTE. Upon the repayment by the Company of all of its
obligations  hereunder to the Holder,  including,  without limitation,  the face
amount  of this  Note,  plus  accrued  but  unpaid  interest,  the  indebtedness
evidenced hereby shall be deemed canceled and paid in full.  Except as otherwise
required  by law or by the  provisions  of this Note,  payments  received by the
Holder hereunder shall be applied first against  expenses and indemnities,  next
against  interest accrued on this Note, and next in reduction of the outstanding
principal balance of this Note.

      7. SEVERABILITY. If any provision of this Note is, for any reason, invalid
or  unenforceable,  the remaining  provisions of this Note will  nevertheless be
valid and enforceable and will remain in full force and effect. Any provision of
this  Note  that is held  invalid  or  unenforceable  by a  court  of  competent
jurisdiction  will be deemed  modified to the extent  necessary to make it valid
and enforceable and as so modified will remain in full force and effect.

      8.  AMENDMENT  AND WAIVER.  This Note may be amended,  or any provision of
this Note may be waived,  provided  that any such  amendment  or waiver  will be
binding on a party  hereto  only if such  amendment  or waiver is set forth in a
writing executed by the parties hereto. The waiver by any such party hereto of a
breach of any  provision  of this Note shall not  operate or be  construed  as a
waiver of any other breach.

      9. SUCCESSORS.  Except as otherwise provided herein,  this Note shall bind
and inure to the benefit of and be  enforceable  by the parties hereto and their
permitted successors and assigns.

      10. ASSIGNMENT.  This Note shall not be directly or indirectly  assignable
or  delegable  by the  Company.  The Holder may assign this Note as long as such
assignment complies with the Securities Act of 1933, as amended.

                                       3


      11. NO STRICT CONSTRUCTION.  The language used in this Note will be deemed
to be the language  chosen by the parties hereto to express their mutual intent,
and no rule of strict construction will be applied against any party.

      12. FURTHER  ASSURANCES.  Each party hereto will execute all documents and
take such other  actions as the other party may  reasonably  request in order to
consummate the  transactions  provided for herein and to accomplish the purposes
of this Note.

      14.  REMEDIES,  OTHER  OBLIGATIONS,  BREACHES AND INJUNCTIVE  RELIEF.  The
Holder's  remedies  provided in this Note shall be cumulative and in addition to
all other remedies  available to the Holder under this Note, at law or in equity
(including a decree of specific  performance and/or other injunctive relief), no
remedy of the Holder  contained  herein  shall be deemed a waiver of  compliance
with the  provisions  giving rise to such remedy and nothing  herein shall limit
the Holder's  right to pursue  actual  damages for any failure by the Company to
comply with the terms of this Note.  Every right and remedy of the Holder  under
any document  executed in connection with this transaction may be exercised from
time to time and as often as may be deemed expedient by the Holder.  The Company
acknowledges  that  a  breach  by it of its  obligations  hereunder  will  cause
irreparable  harm to the Holder  and that the remedy at law for any such  breach
may be inadequate.  The Company  therefore agrees that, in the event of any such
breach or threatened  breach,  the Holder shall be entitled,  in addition to all
other available remedies, to an injunction  restraining any breach, and specific
performance  without the necessity of showing economic loss and without any bond
or other security being required.

      15.   GOVERNING   LAW;   JURISDICTION.   All  questions   concerning   the
construction,  validity,  enforcement and interpretation of this Agreement shall
be governed by the  internal  laws of the State of New  Jersey,  without  giving
effect to any choice of law or conflict of law provision or rule (whether of the
State of New Jersey or any other jurisdictions) that would cause the application
of the laws of any jurisdictions  other than the State of New Jersey. Each party
hereby  irrevocably  submits  to the  exclusive  jurisdiction  of the  state and
federal courts sitting in Essex County,  New Jersey, for the adjudication of any
dispute  hereunder  or  in  connection  herewith  or  therewith,   or  with  any
transaction  contemplated  hereby or discussed  herein,  and hereby  irrevocably
waives,  and agrees not to assert in any suit,  action or proceeding,  any claim
that it is not personally  subject to the  jurisdiction of any such court,  that
such suit, action or proceeding is brought in an inconvenient  forum or that the
venue of such  suit,  action  or  proceeding  is  improper.  Each  party  hereby
irrevocably  waives  personal  service of process and consents to process  being
served in any such suit,  action or proceeding by mailing a copy thereof to such
party at the address for such notices to it under this Agreement and agrees that
such service shall constitute good and sufficient  service of process and notice
thereof.  Nothing contained herein shall be deemed to limit in any way any right
to serve process in any manner permitted by law.

      16. NO INCONSISTENT AGREEMENTS.  None of the parties hereto will hereafter
enter into any agreement,  which is inconsistent  with the rights granted to the
parties in this Note.

      17.  THIRD  PARTIES.  Nothing  herein  expressed or implied is intended or
shall be  construed  to confer upon or give to any person or entity,  other than
the parties to this Note and their respective  permitted  successor and assigns,
any rights or remedies under or by reason of this Note.

      18. WAIVER OF JURY TRIAL. AS A MATERIAL  INDUCEMENT FOR THE HOLDER TO LOAN
TO THE COMPANY THE MONIES  HEREUNDER,  THE  COMPANY  HEREBY  WAIVES ANY RIGHT TO
TRIAL BY JURY IN ANY LEGAL PROCEEDING RELATED IN ANY WAY TO THIS NOTE AND/OR ANY
AND ALL OF THE OTHER DOCUMENTS ASSOCIATED WITH THIS TRANSACTION.

                                       5


      19. ENTIRE AGREEMENT. This Note (including the recitals hereto) sets forth
the entire  understanding  of the parties  with  respect to the  subject  matter
hereof, and shall not be modified or affected by any offer, proposal,  statement
or representation,  oral or written, made by or for any party in connection with
the  negotiation  of the terms hereof,  and may be modified only by  instruments
signed by all of the parties hereto.
