                               FIRST AMENDMENT TO
                      MASTER LOAN AND INVESTMENT AGREEMENT
                      ------------------------------------

     THIS FIRST AMENDMENT TO MASTER LOAN AND INVESTMENT AGREEMENT (together with
all Exhibits hereto,  this "AMENDED  AGREEMENT") is made this 25 day of October,
2004,  by and among KRONOS  ADVANCED  TECHNOLOGIES,  INC.,  F/K/A TSET,  INC., a
Nevada  corporation,  whose principal place of business is located at 464 Common
St., Suite 301, Belmont,  MA 02478 ("KRONOS");  KRONOS AIR TECHNOLOGIES  INC., a
Nevada  corporation,  whose principal place of business is located at 8551 154th
Avenue NE, Redmond,  WA 98052 ("KRONOS  AIR");  and FKA  DISTRIBUTING  CO. D/B/A
HOMEDICS,  INC., a Michigan  corporation,  whose  principal place of business is
located at 3000 Pontiac Trail,  Commerce Township,  Michigan 48390 ("HOMEDICS").
Kronos and Kronos Air are collectively referred to herein as the "BORROWERS" and
individually as a "BORROWER."

                                R E C I T A L S:

A.   The  Borrowers  desired  to  borrow up to  $3,400,000  from  HoMedics,  and
     HoMedics  agreed  to loan  such  funds to the  Borrowers  on the  terms and
     conditions set forth in that certain  Master Loan and Investment  Agreement
     executed  on  May  9,  2003  between   HoMedics  and  the  Borrowers   (the
     "AGREEMENT").

B.   The Borrowers failed to make their August 2004 payment to HoMedics. In July
     of 2004 the Borrowers  began  negotiating  with HoMedics to provide  future
     flexibility for Borrowers to make their required  payments and to secure an
     obligation  from  HoMedics  to fund an  additional  loan in the  amount  of
     $925,000.

C.   On October  15,  2004,  HoMedics  agreed to forbear  from taking any action
     under  the  Agreement  pursuant  to the terms of that  certain  forbearance
     letter  attached  hereto  as  Exhibit  A and  incorporated  herein  by this
     reference

D.   During  negotiations  with HoMedics  concerning the Agreement,  the parties
     executed the Second Amendment to their Exclusive Licensing Agreement, which
     was executed on September 24, 2004 (the "AMENDED LICENSE Agreement").

E.   This Amended  Agreement,  together  with the  execution and delivery of the
     documents referred to herein, should provide the Borrowers with significant
     flexibility without the threat of a potential default in the near future.

F.   The execution of this Amended  Agreement  and all the related  documents is
     occurring  subsequent to Kronos' execution of the following  documents with
     Cornell  Capital  Partners,  LP  ("CORNELL"),  which commit  Cornell to (i)
     purchase $500,000 of Kronos stock (the "$.5M EQUITY INVESTMENT") subject to
     the  execution of this Amended  Agreement;  (ii) loan  $4,000,000 to Kronos
     under two Equity Backed  Promissory Notes  (collectively,  the "$4M NOTE");
     and (iii) perform certain  obligations  under a $20,000,000  Standby Equity
     Distribution  Agreement  (the "SEDA",  which together with the $4M Note and
     the $.5M Equity  Investment  shall hereafter be referred to collectively as
     the "CORNELL INVESTMENT").

G.   All terms not otherwise defined herein shall have the same meaning as those
     terms have in the Agreement.

     NOW,  THEREFORE,  in  consideration of the foregoing and for other valuable
consideration,  the receipt and  adequacy of which is hereby  acknowledged,  the
parties hereto agree as follows:


                                   ARTICLE I
                                   ---------
                  LOAN AND INVESTMENT COMMITMENT AND DOCUMENTS
                  --------------------------------------------

     1.1 LOAN AND INVESTMENT COMMITMENT. Subject to the terms and conditions set
forth herein,  HoMedics hereby agrees to lend the Borrowers and invest in Kronos
up to an additional $925,000 (the "INVESTMENT PROCEEDS") as follows:

         A. Upon the  execution  and  delivery  by the  parties of this  Amended
Agreement  and the  execution  and delivery by the  Borrowers of the  Investment
Documents (defined below) identified in Section 1.2, HoMedics agrees to loan the
Borrowers up to an additional  $925,000 (the "$925,000  LOAN").  The proceeds of
the $925,000 Loan shall be funded when Kronos attains the following milestones:

            (i) First,  $175,000  shall be funded  upon  Flextronics  delivering
    boards/power  supply that can be plugged  into  prototypes  as  delivered by
    Flextronics  and  the  prototype,   with  the  Flextronics  boards  and  the
    components from CP Tech, attains the same or better testing results as those
    achieved in the August 13th and 25th testings (the "FIRST MILESTONE").

            (ii) Second,  $250,000  shall be funded upon  obtaining 1) prototype
    tooling of the current prototype  configuration;  2) testing for performance
    to spec; and 3) performing to spec (the "SECOND MILESTONE").

            (iii)  The  last  $500,000  shall  be  funded  upon  the  Production
    Effective Date, as such term is defined in the Exclusive Licensing Agreement
    dated  October 23, 2002 between  Kronos and HoMedics,  as amended  ("LICENSE
    AGREEMENT"),  as the same  may be  amended  from  time to time  (the  "THIRD
    MILESTONE," which together with the First Milestone and Second Milestone are
    collectively referred to as the "MILESTONES").

     Upon Kronos  attaining each Milestone,  HoMedics shall fund the appropriate
amount of loan  proceeds  into an escrow  account at the Law Offices of Seyburn,
Kahn, Ginn, Bess and Serlin,  P.C. to be disbursed  pursuant to the terms of the
Escrow Agreement attached hereto as Exhibit 1.1A (the "ESCROW AGREEMENT"), which
is incorporated  herein by this reference.  Such loan proceeds shall be released
from the escrow account, as provided in the Escrow Agreement.

                                       2


         B. Upon the  execution  and  delivery  by the  parties of this  Amended
Agreement,  Warrant  No. 3 and the  Amended  and  Restated  Registration  Rights
Agreement,  HoMedics shall acquire  Warrant No. 3 (as defined below) from Kronos
in exchange for $75,000 and  HoMedics'  agreement  herein to loan an  additional
$925,000 as set forth more  specifically  in Section 1.1A above.  HoMedics shall
deduct from such proceeds the Closing Fees (as defined in Section 2.3 below).

     1.2 INVESTMENT DOCUMENTS. The loans made pursuant to this Amended Agreement
shall be evidenced by the following documents and instruments:

         A.  AMENDED AND RESTATED  $2.4 MILLION  SECURED  PROMISSORY  NOTE.  The
$2,400,000 already loaned by HoMedics to the Borrowers pursuant to the Agreement
and the $2.4M Note shall be amended and restated as evidenced by the Amended and
Restated  Secured  Promissory  Note in the form of EXHIBIT  1.2(A) (the "AMENDED
$2.4M NOTE").  Interest shall accrue on the outstanding principal balance of the
$2.4M Note at the rate of 6% per annum  with a  maturity  date of five (5) years
from the date of this  Agreement  (the  "MATURITY  DATE").  No payments shall be
required  under the  Amended  $2.4M  Note until the  earlier of (i) the  quarter
following the Production  Effective Date; or (ii)  twenty-four  (24) months from
the date of this  Amended  Agreement  (the  "REPAYMENT  START  DATE").  Interest
accrued  during such period  shall become part of the  principal  balance of the
note and  shall be  included  as  principal  in any  amortization  of the  note.
Payments of principal and accrued  interest shall be payable in equal  quarterly
installments beginning on the first day of the quarter after the Repayment Start
Date and continuing on the first day of each November,  February, May and August
until paid in full by the  Maturity  Date.  Any payments  made by the  Borrowers
shall first be applied against the quarterly payment due under the Amended $2.4M
Note and then to the quarterly  payment due under the $925,000 Note described in
subsection (B) below.

         B.  $925,000  SECURED  PROMISSORY  NOTE.  The  $925,000 to be loaned by
HoMedics to the Borrowers shall be evidenced by a Secured Promissory Note in the
form of EXHIBIT  1.2(B) (the  "$925,000  NOTE").  Interest  shall  accrue on the
outstanding  principal  balance of the $925,000 Note at the rate of 6% per annum
and shall also mature on the Maturity Date. No payments of principal or interest
shall be required  under the $925,000 Note until the  Repayment  Start Date (the
"ACCRUAL PERIOD").  Interest accrued during the Accrual Period shall become part
of the principal balance of the $925,000 Note and shall be included as principal
in any  amortization  of the $925,000  Note.  Payments of principal  and accrued
interest shall be payable in equal quarterly installments beginning on the first
day of the quarter  after the Repayment  Start Date and  continuing on the first
day of  each  November,  February,  May  and  August  until  paid in full by the
Maturity Date.

         C. STOCK  PURCHASE  WARRANT  NO. 3.  Kronos  shall  issue to HoMedics a
warrant in the form of EXHIBIT  1.2(C)  ("Warrant No 3") to purchase  26,507,658
shares of Kronos  Common Stock  (defined in Section  3.9(A)) (the "WARRANT NO. 3
SHARES").  Warrant No. 3 shall be exercisable  for a period of 10 years from the
date of issue. The exercise price shall be $0.10 per share.  Warrant No. 3 shall
contain the provisions  described in Section 1.2(E) herein. In consideration for
Warrant No. 3 granted  pursuant to this  Amended  Agreement,  HoMedics is hereby
deemed to  deliver  to Kronos  $75,000  by  funding  the  Closing  Fees owed and

                                       3



HoMedics has agreed to amend  Warrant  Nos. 1 and 2 to remove the  anti-dilution
protection  previously  granted as set forth in the Amended and Restated Warrant
No. 1 and the Amended and Restated Warrant No. 2 in the forms attached hereto as
Exhibits  1.2(C)(1) and (C)(2).

         D.  REGISTRATION   RIGHTS   AGREEMENT.   Kronos  shall  grant  HoMedics
piggy-back  registration  rights  and one (1)  demand  registration  right  with
respect to any shares of Kronos  Common Stock that it may acquire  under Warrant
Nos. 1, 2 and 3 pursuant to the terms and  conditions of an Amended and Restated
Registration  Rights  Agreement,  in the form of EXHIBIT  1.2(D)  (the  "AMENDED
REGISTRATION  RIGHTS  AGREEMENT").  HoMedics  agrees not to exercise (i) Warrant
Nos.  1,2 and 3 by means of a "cashless  exercise"  for one year  following  the
effective date of the registration  statement to be filed by Kronos with the SEC
for the Cornell  Investment;  (ii) its demand  registration  rights for one year
following the effective date of the registration statement to be filed by Kronos
with the SEC for the Cornell  Investment,  and (iii) its piggyback  registration
rights with respect to the registration statement the Company plans to file with
the SEC with respect to the Cornell Investment on or about October 24, 2005.

         E. DILUTION.  If Kronos shall issue,  at any time after the date hereof
and before the  exercise by HoMedics  of Warrant No. 3 and any  warrants  issued
pursuant to this Section 1.2(E), any Common Stock, warrants, options, or similar
rights to acquire  Common Stock at an issue price,  exercise price or value less
than $0.20 per share,  and  following  such  securities  issuance  the shares of
Common Stock  issuable to HoMedics  under Warrant No. 3 and any warrants  issued
pursuant to this Section 1.2(E),  in the aggregate,  represents less than thirty
percent (30%) of the Common Stock that is issued and  outstanding as of the date
of such securities issuance, on a fully diluted basis assuming the conversion or
exchange of all outstanding convertible securities of Kronos and the exercise of
all  outstanding  options,  warrants or similar  rights to acquire Common Stock,
then  Kronos  shall  issue  to  HoMedics  (without  the  payment  of  additional
consideration)  additional warrants, in the same form as Warrant No. 3 (and with
the same  expiration  date),  so that the number of shares of Common  Stock that
HoMedics may acquire pursuant to Warrant Nos. 1, 2 and 3 and any warrants issued
pursuant to this Section  1.2(E),  in the aggregate,  shall equal thirty percent
(30%) of the Common Stock, on a fully diluted basis,  assuming the conversion or
exchange  of all  outstanding  options,  warrants  or similar  rights to acquire
Common Stock (except for  unexercised  options  issued to  employees,  officers,
directors and consultants constituting Option Shares as defined in Section 3.9).

     The calculation of the additional warrants to be issued to provide HoMedics
with 30% of Kronos  Common Stock on a fully  diluted  basis (the  "ANTI-DILUTIVE
WARRANTS TO BE ISSUED") shall be calculated pursuant to the following formula:

     Kronos Shares  Outstanding  Post-Dilution  Event (Fully  Diluted  Excluding
     Option Shares) / 70% = Total Shares Outstanding (Fully Diluted)

     Total  Shares  Outstanding  (Fully  Diluted)  - Kronos  Shares  Outstanding
     Post-Dilution Event (Fully Diluted) = Total HoMedics Warrants

     Total  HoMedics  Warrants - HoMedics  Warrants Owned  Pre-Dilution  Event =
     Anti-Dilutive Warrants to be Issued

                                       4



     Notwithstanding  anything to the  contrary  set forth  herein this  Section
1.2(E),  HoMedics hereby waives its right to receive any additional  warrants it
would  otherwise  be entitled to receive  pursuant to this  Section  1.2(E) with
respect to all shares of Common Stock that Kronos  sells to Cornell  pursuant to
the SEDA, the proceeds of which are directly used to repay the $4M Note.

     3.9 ISSUANCE OF SECURITIES.

         A.  CAPITALIZATION.  As more specifically  described in EXHIBIT 3.9(A),
the  authorized  capital  stock  of  Kronos  consists  of five  hundred  million
(500,000,000)  shares of common stock, $.001 par value per share ("KRONOS COMMON
STOCK"),  of which 100,556,884  shares are currently issued and outstanding (the
"OUTSTANDING SHARES"),  including,  as of the date hereof, a reserve for options
to acquire  approximately  12,813,812 shares of Kronos Common Stock (the "OPTION
SHARES")  and a reserve  for  warrants  to acquire  15,792,342  shares of Kronos
Common Stock (the "WARRANT SHARES").  The Outstanding  Shares, the Option Shares
and the Warrant  Shares,  when issued,  constitute or will constitute all of the
issued and outstanding  capital stock of Kronos,  and all of such securities are
validly  issued,  fully paid  (other than the payment of the price to be paid in
connection  with the  exercise  of the Option  Shares and the  Warrant  Shares),
nonassessable,  and have been so issued in full  compliance  with all applicable
federal and state securities laws. Other than Agreements  relating to the Option
Shares,  Warrant  Shares and the Cornell  Investment,  there are no  outstanding
subscriptions,  options,  rights,  warrants,  convertible  securities  or  other
Agreements or commitments providing for the issuance, disposition or acquisition
of any of Kronos' capital stock (other than this Amended  Agreement).  There are
no outstanding or authorized stock appreciation,  phantom stock or similar right
with  respect to Kronos,  and there are no voting  trusts,  proxies or any other
Agreements or understandings  with respect to the voting of the capital stock of
Kronos.  Kronos is not subject to any  obligation  (contingent  or otherwise) to
repurchase or otherwise acquire or retire any of its capital stock.

         B. There are  26,507,658  shares of Kronos  Common Stock that have been
duly  authorized  and reserved for issuance upon exercise of Warrant No. 3. Upon
issuance and payment  therefor in  accordance  with the terms and  conditions of
this Amended  Agreement and Warrant No. 3, such shares shall be validly  issued,
fully paid and non-assessable  and free from all taxes, liens and charges,  with
the holders being  entitled to all rights  accorded to a holder of Kronos Common
Stock.

     3.10  MATERIAL  AGREEMENTS.  Each Borrower has and, to its  knowledge,  all
parties to each of the material  licenses,  contracts or commitments of any kind
(including,  without limitation,  employment  Agreements,  collective bargaining
Agreements,  powers of  attorney,  distribution  contracts,  patent or trademark
licenses,  bonus,  pension  and  retirement  plans,  or  accrued  vacation  pay,
insurance and welfare  Agreements)  have,  complied with the  provisions of such
licenses,  contracts  or  commitments  and,  neither  Borrower  is  and,  to its

         A.  Neither  Borrower is a party to any  litigation  or  administrative
proceeding, nor to the best of the knowledge of each Borrower, is any litigation
or administrative proceeding threatened against it, which in either case asserts
or alleges that (a) either Borrower  violated any federal,  state or local laws,
ordinances,   statute,   rules  or  regulations   governing  the  use,  storage,
transportation,  or disposal of Hazardous Materials  ("ENVIRONMENTAL LAWS"); (b)

portion  of the cost of any past,  present,  or  future  clean  up,  removal  or
remedial  or other  response  action  which  arises  out of or is related to the
disposal,  depositing,  discharge,  leaking or other  release  of any  Hazardous
Materials on any of its properties or with respect to any of its assets.

         B. To the best  knowledge  of each  Borrower,  there are no  conditions
existing which would subject either Borrower to damages,  penalties,  injunctive
relief or clean up costs under any  Environmental  Laws or which  require or are
likely to require clean up,  removal,  remedial  action or other response action
pursuant to Environmental Laws by it.

         C.  Neither  Borrower  is subject  to any  judgment,  decree,  order or
citation related to or arising under the Environmental  Laws and either Borrower
has not received any notice  ("ENVIRONMENTAL  COMPLAINT")  of any  violations of
Environmental  Laws, and to the best of each  Borrowers'  knowledge,  there have
been  no  actions   commenced  or  threatened   against  it  by  any  party  for
noncompliance with any Environmental Laws.

         D.  Each  Borrower  has all  permits,  licenses,  approvals  and  other
authorizations required under the Environmental Laws.

     3.12 MISREPRESENTATION.  No warranty or representation  contained herein or
in any  certificate  or other  document  furnished to HoMedics  pursuant  hereto
contains any untrue statement of material fact or omits to state a material fact
necessary to make such warranty or representation not misleading in light of the
circumstances  under which it was made.  There is no fact which either  Borrower
has not  disclosed to the HoMedics in writing  which  materially  and  adversely
affects  or  is  likely  to  materially  and  adversely   affect  the  business,
operations, properties, prospects, profits or condition (financial or otherwise)
of either  Borrower  or the  ability of either  Borrower  to perform  the Kronos
Agreements.

rights or licenses to use all material  trademarks,  trade names, service marks,
service mark registrations,  authorizations,  trade secrets and rights necessary

trademarks,  trade names,  service marks,  service mark  registrations,  service
names, patents,  patent rights,  copyrights,  inventions,  licenses,  approvals,
government  authorizations,  trade secrets or other intellectual property rights
have  expired or  terminated,  or, by the terms and  conditions  thereof,  could
expire or terminate  within two years from the date of this  Amended  Agreement.
Neither  Borrower  is  infringing,  and  does  not  have  any  knowledge  of any
infringement  of any third party with respect to any material  trademark,  trade
name rights, patents, patent rights, copyrights,  inventions,  licenses, service
names, service marks, service mark registrations,  trade secret or other similar
rights of others,  or of any such  development  of similar  or  identical  trade

against either Borrower regarding trademark, trade name, patents, patent rights,
invention,  copyright,  license,  service  names,  service  marks,  service mark
registrations,  trade secret or other  infringement,  which could  reasonably be
expected  to have a material  adverse  effect on either  Borrower or its assets,
operations or business.

     3.14  INSURANCE.  Each  Borrower  is  insured  by  insurers  of  recognized
financial  responsibility  against  such losses and risks and in such amounts as
management  of  each  Borrower  believes  to be  prudent  and  customary  in the
businesses in which each Borrower is engaged.  Neither Borrower has been refused
any insurance coverage sought or applied for and each Borrower does not have any
reason  to  believe  that it will not be able to renew  its  existing  insurance
coverage as and when such coverage  expires,  or to obtain similar coverage from
similar  insurers as may be  necessary  to continue  its business at a cost that
would not materially and adversely affect its condition, financial or otherwise,
or earnings, business or operations.

     3.15  APPLICATION OF TAKEOVER  PROTECTIONS.  Each Borrower and its Board of
Directors  have taken or will take prior to the  Production  Effective  Date all

a  rights  Agreement)  or  other  similar  anti-takeover   provision  under  the
Certificate of Incorporation or the laws of the state of its incorporation.

furnishing  of  services  to or by,  providing  for  rental of real or  personal

SECURITIES"); PROVIDED, HOWEVER, that "New Securities" do not include:

            1.  Securities  issued in connection  with any stock  splits,  stock

            2.  Any  securities  issued  to  employees,   officers,   directors,
    consultants  or other persons  performing  services for Kronos (if so issued

                                       14



    solely  because  of  any  such  person's  status  as an  officer,  employee,
    director, consultant or other person performing services for Kronos, and not
    as part of any other  offering of Kronos  securities)  pursuant to any stock
    option plan, stock purchase plan or management  incentive plan, Agreement or
    arrangement approved by Kronos' Board of Directors;

            3. Any Kronos Common Stock issued upon the  conversion,  exercise or
    exchange of Warrant Nos. 1, 2 and 3; and

            4.  Shares  issued  to  Cornell  under  the terms of the SEDA to the
    extent that Kronos has issued such shares for the direct purpose of repaying
    the $4M Note to Cornell.

any New Securities, Kronos shall first give HoMedics written notice stating such
intention.  The written  notice  shall  contain a full,  accurate  and  complete
description  of the price and terms of such proposed  sale, and shall contain an
unconditional  offer to sell a Pro Rata  Share (as  defined  in  Subsection  (D)
below) of such New  Securities  to HoMedics on the same terms and  conditions as
set forth in the notice.  HoMedics  shall have ten (10)  business  days from the
date such written  notice is given to elect to purchase all or a portion of such
Pro Rata Share of the New Securities, by giving written notice to Kronos of such
election  and the  quantity  of New  Securities  that  HoMedics  will  purchase,
together with payment for such New Securities.

         C. If HoMedics elects to purchase any of the New Securities  within the
election periods described in subsection (B), Kronos shall deliver to HoMedics a
certificate  or other  instrument  evidencing the New Securities by the close of
business on the  fifteenth  day (or if such day is not a business  day, the next
succeeding  business day) after the receipt of HoMedics'  notice of election and
its payment for the shares acquired.

         D. As used in this  subsection  4.5,  the "PRO  RATA  SHARE" of the New
Securities  that  HoMedics  will be  offered an  opportunity  to  purchase  is a
fraction  of the total New  Securities  proposed  to be  issued,  calculated  as
follows:  (i) the  numerator  of the  fraction  shall be the number of shares of
Kronos  Common  Stock that could be  obtained  by HoMedics  upon  conversion  or
exchange on such date of any securities  convertible  into or  exchangeable  for
Kronos  Common Stock plus the number of shares of Kronos Common Stock that could
be acquired by  HoMedics  on such date upon  exercise of any option,  warrant or
similar right (other than by exercise of preemptive rights hereunder);  and (ii)
the  denominator  of the  fraction  shall be the  aggregate  number of shares of
Kronos Common Stock outstanding on such date calculated on a fully diluted basis
assuming the conversion or exchange of all  outstanding  convertible  securities
and the  exercise of all  outstanding  options,  warrants  or similar  rights to
acquire Kronos Common Stock.

         E. During the sixty (60) day period following the expiration of the ten
(10) business day election  period  described in the last sentence of subsection
(B) hereof,  Kronos may issue the New Securities that HoMedics has not purchased
pursuant to this subsection 4.5, but only on terms and conditions and at a price
no more  favorable  to the  purchasers  thereof  than was  specified in Kronos's
notice to HoMedics.

                                       15



         F. The rights of HoMedics under this  subsection 4.5 may be waived,  in
whole or part,  with respect to any  proposed  issuance of New  Securities  if a
written waiver is executed by HoMedics.  Such waiver may be obtained at any time
prior to,  contemporaneously  with or after the actual issuance by Kronos of the
New Securities.

HoMedics shall also stand as collateral  security for the  indebtedness  and all
obligations  of  either  Borrower  hereunder  to  HoMedics;  (B) all  collateral
hereunder  shall  stand  as  collateral   security  for  all   indebtedness  and
obligations of the Borrowers now or at any time hereafter owed to HoMedics;  (C)
