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

     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 $3,500,000 (the "Investment Proceeds") as follows:

            A.    Upon  the  execution  and  delivery  by the  parties  of  this
            Agreement  and the  execution  and delivery by the  Borrowers of the
            Investment  Documents  (defined below) identified in Section 1.2(A),
            1.2(C), 1.2(D), 1.2 (E), 1.2(F) and 1.2(G),  HoMedics shall loan the
            Borrowers  an amount  equal to  $2,400,000,  payable in  immediately
            available funds by wire transfer to an account designated by Kronos.
            HoMedics  shall  deduct from such loan  proceeds  Closing  Costs (as
            defined in Section 2.3 below) in an amount equal to $25,000.

            B.    Provided  that the  Borrowers  are not in  default  under this
            Agreement or under any of the Investment Documents then outstanding,
            upon the execution  and delivery by the Borrowers of the  Investment
            Documents  identified  in Section  1.2(B),  HoMedics  shall loan the
            Borrowers an additional $1,000,000. The loan contemplated under this
            Section  1.1(B) shall be made no later than five (5)  business  days



            following the  Production  Effective Date as such term is defined in
            the Exclusive Licensing  Agreement,  dated October 23, 2002, between
            Kronos and HoMedics ("License Agreement"), an executed copy of which
            is attached as Exhibit 1.1(B),  as the same may be amended from time
            to time, and no earlier than the Production Effective Date. HoMedics
            shall  deduct  from such loan  proceeds  Closing  Costs in an amount
            equal  to  $25,000,  provided,   however,  that  if  the  Production
            Effective  Date does not occur  within  thirty (30) months after the
            Effective  Date of the  License  Agreement,  the  $25,000 in Closing
            Costs shall be immediately payable by the Borrowers to HoMedics.

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

                  A.    $2.4 MILLION SECURED  PROMISSORY.  The $2,400,000 loaned
            by HoMedics to the Borrowers  pursuant to Section 1.1(A) above shall
            be  evidenced  by a Secured  Promissory  Note in the form of EXHIBIT
            1.2(A) (the "$2.4M Note").  Interest shall accrue on the outstanding
            principal  balance of the $2.4M Note at the rate of six (6%) percent
            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 note during the first twelve (12) months thereof. Interest
            accrued  during  such  12  month  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 August 1, 2004 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  $2.4M  Note and then to the
            quarterly  payment due under the $1.0M Note  described in subsection
            (B) below.

                  B.    $1  MILLION  SECURED  PROMISSORY  NOTE.  The  $1,000,000
            loaned by HoMedics to the Borrowers pursuant to Section 1.1(B) above
            shall  be  evidenced  by a  Secured  Promissory  Note in the form of
            EXHIBIT  1.2(B) (the "$1.0M  Note").  Interest  shall  accrue on the
            outstanding  principal  balance of the $1.0M Note at the rate of six
            (6%) percent per annum and shall also mature on the  Maturity  Date.
            If the $1.0M Note is issued prior to the first  anniversary  date of
            this  Agreement,  no payments  of  principal  or  interest  shall be
            required  under the note  until  such  first  anniversary  date (the
            "Accrual Period").  Interest accrued during the Accrual Period shall
            become  part of the  principal  balance  of the  Note  and  shall be
            included  as  principal  in any  amortization  of the note.  In this
            event,  payments of principal and accrued  interest shall be payable
            in equal  quarterly  installments  beginning  on  August 1, 2004 and
            continuing  on the first  day of each  November,  February,  May and
            August until paid in full by the Maturity Date. If the $1.0M Note is
            issued  on or after the first  anniversary  date of this  Agreement,
            payments shall be made in equal quarterly  installments beginning on
            the first day of the first quarter month  immediately  following the
            issue date, and continuing until the Maturity Date.

                  C.    SECURITY AGREEMENT. The Borrowers' obligations under the
            $2.4M Note and the $1.0M Note (collectively,  the "Notes") and under
            Section 4.4 of this  Agreement  (Put  Rights)  shall be secured by a
            first priority lien in all of the Borrowers'  assets,  including but


                                       2


            not limited to the patents and  intellectual  property  owned by the
            Borrowers related to the Licensed Technology as such term is defined
            in the License Agreement (the "Intellectual  Property"),  as well as
            the  royalty  payments  owed  to  Kronos  pursuant  to  the  License
            Agreement  (collectively referred to as the "Collateral"),  pursuant
            to the terms and  conditions of a Security  Agreement in the form of
            Exhibit  1.2(C) (the  "Security  Agreement").  As provided  therein,
            HoMedics shall not foreclose upon the  Intellectual  Property during
            the term of the Notes  (exclusive of any  extensions of the original
            term),  so long as the Borrowers do not grant a Lien (defined below)
            in the Intellectual  Property to any third party. In addition to the
            Security Agreement,  the Borrowers shall deliver all other documents
            reasonably  required by HoMedics to perfect the first  priority lien
            in the  Collateral.  For purposes of this  Agreement,  Lien shall be
            defined as any voluntary or  involuntary  lien,  including,  without
            limitation a lien resulting from a bankruptcy proceeding, but, shall
            exclude  mechanics liens.  Notwithstanding  anything to the contrary
            contained in this Agreement,  HoMedics agrees,  that after the Notes
            have been  repaid in full by  Borrowers,  during  the period of time
            that HoMedics has a first priority lien in all of Borrowers' assets,
            HoMedics  will  subordinate  its first  priority lien as long as the
            contemplated  subordination  is to  Borrowers'  qualified  financial
            institution;  otherwise, HoMedics may withhold its subordination for
            any reason, in its sole discretion, to all other parties, including,
            without limitation: (a) a Competitor (defined in Section 4.4), (b) a
            shareholder of either Borrower, or (c) a venture capital investor or
            venture capital group.

                  D.    Assignment   of   License   Agreements.   Kronos   shall
            collaterally  assign to  HoMedics  the  royalty  payments  under the
            License  Agreement,  pursuant  to the  terms and  conditions  of the
            Security Agreement.

                  E.    STOCK  PURCHASE  WARRANT  NO. 1.  Kronos  shall issue to
            HoMedics a warrant in the form of Exhibit  1.2(E)  ("Warrant No. 1")
            to purchase  6,746,171  shares of Kronos  Common  Stock  (defined in

            that is issued and outstanding as of the date of this Agreement,  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 (the  "Warrant  No. 1 Shares").  Warrant No. 1 shall be
            exercisable  for a period of ten (10)  years from the date of issue.
            The  exercise  price  shall be $0.10 per share.  Warrant No. 1 shall
            contain  the  provisions  described  in Section  1.2(H)  herein.  In
            consideration  for Warrant No. 1 and Warrant No. 2 granted  pursuant
            to this  Agreement,  HoMedics  hereby  delivers  to Kronos  $100,000

            ten (10%) of Kronos Common Stock that is issued and  outstanding  as
            of the date of this Agreement, 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 (the "Warrant No. 2 Shares"). Warrant
            No. 2 shall be  exercisable  for a period of ten (10) years from the


                                       3


            date of issue. The exercise price shall be $0.10 per share.  Warrant
            No. 2 shall  contain  the  provisions  described  in Section  1.2(H)
            herein.  Warrant No. 2 shall be  exercisable by HoMedics only if (1)
            the  Borrowers  do not  prepay the entire  amount of  principal  and
            interest due under the Notes by November 8, 2005;  (2) either of the
            Borrowers are in default under any of the Investment  Documents,  or

            Agreement  but prior to November 8, 2005,  Revenues in an  aggregate

            relationship representing a license or sale of the Kronos technology
            to any third party or parties  (other than proceeds from the License
            Agreement,  without  taking  into  account any  amendment  thereof).
            Revenues shall not include revenues which Kronos earns from research
            and development contracts.

                  G.    REGISTRATION   RIGHTS   AGREEMENT.   Kronos  will  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,  pursuant  to the  terms and  conditions  of a
            Registration  Rights  Agreement,  in the form of Exhibit 1.2(G) (the
            "Registration Rights Agreement").

                  H.    DILUTION.  If Kronos shall issue,  at any time after the
            date  hereof and before the  exercise  by HoMedics of Warrant No. 1,
            Warrant  No. 2 and any  warrants  issued  pursuant  to this  Section
            1.1(H),  any  security  of Kronos  (outright  or  convertible)  in a
            capital  raising  transaction  in which the Kronos  Common  Stock is
            issued at a price  less than  $0.20 per share,  and  following  such
            securities  issuance the shares of Kronos  Common Stock  issuable to
            HoMedics under Warrant No. 1, Warrant No. 2 and any warrants  issued
            pursuant to this Section  1.1(H) in the aggregate,  represents  less
            than fifteen percent (15%) of Kronos 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 Kronos Common Stock,
            Kronos shall issue to HoMedics additional warrants, in the same form
            as  Warrant  No. 1, so that the  number  of shares of Kronos  Common
            Stock that  HoMedics may acquire  pursuant to Warrant No. 1, Warrant
            No. 2 and any warrants issued  pursuant to this Section  1.1(H),  in
            the  aggregate,  shall equal fifteen  percent (15%) of Kronos Common
            Stock,  on a fully  diluted  basis (or seven  and  one-half  percent
            (7.5%) for  Warrant No. 1 or Warrant  No. 2,  individually).  In the
            event  Kronos  shall  issue  any  security  of Kronos  (outright  or
            convertible)  in a capital  raising  transaction in which the Kronos
            Common  Stock is issued at a price  greater  than  $0.20 per  share,
            HoMedics shall not be entitled to any additional  warrants  pursuant
            to this Agreement.

under any such indenture,  note, agreement or other instrument; and (E) will not
result in the creation or imposition of any lien,  charge or  encumbrance of any

      3.3   NO LITIGATION.  Except as set forth in the SEC Documents (as defined
below), there are no actions, suits or proceedings,  at law or in equity, and no
proceedings  before any arbitrator or by or before any governmental  commission,
board,  bureau,  or  other  administrative  agency,  pending,  or,  to the  best
knowledge  of each  Borrower,  threatened  against or affecting it or any of its
properties or rights which, if adversely  determined could materially impair its
right to carry on its business  substantially  as now  conducted,  or could have
material adverse effect upon the financial  condition of either  Borrower.  "SEC
DOCUMENTS" shall mean Annual Reports on Form 10-KSB,  Quarterly  Reports on Form

properties of either  Borrower,  including  without  limitation the Intellectual
Property, are subject to any mortgage,  pledge, lien, security interest or other

the purposes of, or in connection  with,  this  Agreement  and the  transactions

accounting  principles,  consistently  applied  ("GAAP")  (except  as  disclosed
therein),  and do or will fairly present the financial condition of Kronos as of
the dates, and the results of its operations for the periods, for which the same

obligations,  liabilities  for taxes,  long-term  leases or  unusual  forward or
long-term commitments not disclosed by the financial statements set forth in the
SEC Documents that have been issued by either Borrower prior to the date of this
Agreement.

      3.6   TAXES.  Each  Borrower  has filed all  federal,  state and local tax
returns and other reports they are required by law to file,  have paid or caused
to be paid all taxes,  assessments and other governmental charges that are shown
to be due and payable under such returns,  and have made adequate  provision for
the payment of such taxes,  assessments or other governmental charges which have
accrued  but are not yet  payable.  Except  as set  forth in the SEC  Documents,

borrowed or any direct or indirect  obligations under any leases (whether or not
required to be capitalized under GAAP) or any agreements of guarantee or surety.

      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  fifty-four  million  five  hundred
      twenty-seven  thousand  five hundred  sixty-five  (54,527,565)  shares are
      currently issued and outstanding (the "Outstanding  Shares") and as of the
      date  hereof,  certain  persons hold  options  and/or  warrants to acquire
      approximately twelve million nine hundred thirty-four thousand one hundred
      forty-five  (12,934,145)  shares  of  Kronos  Common  Stock  (the  "Option
      Shares"), which, when combined with the Outstanding Shares, constitute the
      total issued and outstanding  capital stock of Kronos,  on a fully diluted
      basis.  The  Outstanding  Shares  and  the  Option  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), 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,  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   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.    Thirteen  million  four  hundred  ninety-two   thousand  three
      hundred  forty-two  (13,492,342)  shares of Kronos  Common Stock have been
      duly  authorized  and reserved for issuance upon exercise of the Warrants.
      Upon  issuance  and  payment  therefor  in  accordance  with the terms and
      conditions  of this  Agreement  and  Warrant No. 1 and Warrant No. 2, 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.

            C.    Kronos owns one hundred  percent (100%) of the common stock of
      Kronos  Air.  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 the
      Kronos Air capital 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,


                                       8


insurance and welfare  agreements)  have,  complied with the  provisions of such
licenses,  contracts  or  commitments  and,  neither  Borrower  is  and,  to its
knowledge,  no other party to such agreements is in default thereunder,  nor has
there  occurred  any event which with  notice or the  passage of time,  or both,
would constitute such a default.

      3.11  ENVIRONMENTAL.
            -------------

            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)  either
      Borrower is required to clean up, remove, or take remedial or other action
      due to the disposal,  depositing,  discharge,  leaking or other release of
      any Hazardous Materials;  or (c) either Borrower is required to pay all or
      a 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.

      3.13  INTELLECTUAL  PROPERTY  RIGHTS.  Each  Borrower  owns  or  possesses
adequate rights or licenses to use all material trademarks, trade names, service
marks,  service mark  registrations,  authorizations,  trade  secrets and rights
necessary to conduct its business as now being conducted. None of the Borrowers'
material  trademarks,  trade names,  service marks,  service mark registrations,


                                       9


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
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  secrets  or  technical  information,  and  there is no  claim,  action or
proceeding being made or brought against, or to each Borrowers knowledge,  being
threatened 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
necessary  action,  if any, in order to render  inapplicable  any control  share
acquisition, business combination, poison pill (including any distribution under
a  rights  agreement)  or  other  similar  anti-takeover   provision  under  the
Certificate of Incorporation or the laws of the state of its incorporation.

      3.16  TRANSACTIONS  WITH  AFFILIATES.  Except  as set  forth  in  the  SEC
Documents,  and other than the grant or exercise of stock  options  disclosed on
Exhibit 3.16, none of the officers,  directors,  or employees of either Borrower
is  presently  a party to any  transaction  with  either  Borrower or any of its
Affiliates  (other than for  services as  employees,  officers  and  directors),
including  any  contract,  agreement  or  other  arrangement  providing  for the
furnishing  of  services  to or by,  providing  for  rental of real or  personal
property to or from,  or  otherwise  requiring  payments to or from any officer,
director  or  such  employee  or,  to  the  knowledge  of  each  Borrower,   any
corporation,  partnership, trust or other entity in which any officer, director,
or any such  employee  has an interest or is an  officer,  director,  trustee or
partner.

                                   ----------
                            COVENANTS AND AGREEMENTS
                            ------------------------

      4.1   AFFIRMATIVE  COVENANTS.  On a continuing basis from the date of this

            A.    Promptly  furnish to HoMedics such  information  regarding its
      operations,  business affairs and financial condition and its subsidiaries
      as HoMedics may reasonably  request from time to time and permit HoMedics,
      its employees, attorneys and agents, to inspect all the books, records and
      properties of each Borrower and their subsidiaries  during normal business

      similar  businesses  to that  of  each  Borrower;  (2)  necessary  workers
      compensation  insurance;   (3)  public  liability  and  product  liability
      insurance  commencing  with  the  sale of  products;  and (4)  such  other
      insurances as may be required by law or as may be  reasonably  required in
      writing by  HoMedics,  all of which  insurance  shall be in such  amounts,
      containing such terms,  in such form, for such purposes,  prepaid for such
      time  period,  and  written  by such  companies  as  shall  be  reasonably
      satisfactory  to HoMedics.  All such  policies  shall contain a provisions
      whereby  they may not be  cancelled  or amended  except upon 30 days prior
      written notice to HoMedics.  Kronos will promptly deliver to HoMedics,  at
      HoMedics' request,  evidence  satisfactory to HoMedics that such insurance
      has been so procured.

            C.    Pay promptly and within the time that they can be paid without
      late  charge,  penalty or  interest  all taxes,  assessments  and  similar
      charges of every kind and nature lawfully levied, assessed or imposed upon
      it and its property,  except to the extent being  contested in good faith.
      If either Borrower shall fail to pay such taxes and assessments within the
      time they can be paid without penalty,  late charge or interest,  HoMedics
      shall have the option to do so and each Borrower  agrees to repay HoMedics
      upon demand,  with interest as provided in the Security  Agreement  and/or
      the Notes, all amounts so expended by HoMedics.

            D.    Do or cause to be done all things  necessary  to preserve  and
      keep in full  force and  effect the  existence,  rights  and  Intellectual

      products utilizing the Licensed Technology, and comply with all applicable
      laws in all material respects,  continue to conduct and operate and at all
      times   maintain,   preserve  and  protect  all  assets   (including   the
      Intellectual  Property),  and from time to time make, or cause to be made,
      all needed and proper improvements,  renewals,  replacements,  and updates
      thereto so that the business  carried on in  connection  therewith  may be
      properly and advantageously conducted at all times.


            E.    Discuss various Kronos  marketing  issues with HoMedics and/or
      Ron Ferber (collectively,  the "Advisors"). In the event the Advisors play
      a  significant  role in the marketing of a Kronos  product,  determined in
      Kronos'  sole  discretion,  the  Advisors  shall be  entitled  to a fee as
      negotiated between Kronos and the Advisors.

                                       11


            F.    The parties  acknowledge  and agree that the  Amended  License
      anticipates  that Kronos and HoMedics will negotiate the details of one or
      more  amendments to the License  Agreement  and/or one or more  additional
      license agreements and that more fully developed amendments to the License
      Agreement and/or additional  license agreements will need to be negotiated
      by the  parties.  Kronos  agrees to use its best  efforts  to,  and commit
      adequate  resources  to  ensure  that  future  amendments  to the  License
      Agreement and/or additional license agreements are executed by the parties
      and delivered within the time frames set forth in the Amended License.

by delivering to Kronos at any time  following a Trigger Event a written  notice
("Put Notice")  specifying  that HoMedics  desires to sell its shares to Kronos.
Upon receipt of the Put Notice, Kronos shall be obligated to purchase all shares
offered  for sale in the Put Notice at a  purchase  price  equal to the  average

rise to the exercise of rights granted hereunder is Trigger Event (A) below, the
Put Per Share Price as  determined  above shall be multiplied by a factor of ten
(10). As used herein, the term "Trigger Event" means:

            A.    Kronos shall have issued or agreed to issue any  securities to
      a Competitor (as defined below) of HoMedics during the term of the License
      Agreement,  the Amended License or any other license  arrangement  between
      HoMedics  and either  Borrower,  provided,  however,  Kronos  shall not be
      precluded  from issuing  securities to an Affiliate  (defined  below) of a
      Competitor if the proper  protections are put into place, as determined by
      HoMedics in its sole discretion, to prevent the Affiliate from selling any
      Products (as defined in the License Agreement) or Additional  Products (as
      defined in the  Amended  License)  in the  Territories  (as defined in the
      License   Agreement,   Amended  License  and  amendments   thereto)  using
      technology substantially similar to the Licensed Technology (as defined in
      the License Agreement); and/or

            B.    Kronos shall have materially breached its obligations under or
      otherwise  defaulted  under the License  Agreement or the Amended  License
      within ten (10) years after the date of this Agreement.

"COMPETITOR"  shall  mean  a  company  manufacturing,  distributing  or  selling
personal care electrical devices under the health and wellness category.

"AFFILIATE"  shall mean: (i) with respect to any individual,  any member of such
individual's immediate family, and any organization (x) in which such individual
and/or his  Affiliate(s)  own,  directly or indirectly,  more than fifty percent
(50%) of any class of equity security or (y) in which such individual and/or his
Affiliate is the sole general  partner,  the managing  general partner or is the
managing  member,   or  which  is  controlled  by  such  individual  and/or  his
Affiliates,  directly or indirectly;  and (ii) with respect to any  corporation,
partnership,  limited liability company, trust, or other organization, any other
corporation,   partnership,   limited   liability   company,   trust,  or  other
organization, which controls, is controlled by, or is under common control with,
the first-referenced corporation, partnership, limited liability company, trust,
or other organization,  and any individual or entity who is the general partner,
managing member,  officer,  director,  trustee of, or who directly or indirectly
controls,  the  first-referenced  corporation,   partnership,  trust,  or  other
organization;  and (iii) any Affiliate of any other  Affiliate.  For purposes of
this  definition,  the term  "controls,"  "is controlled by" or "is under common
control  with" shall mean the  possession,  direct or indirect,  of the power to
direct or cause the  direction  of the  management  and  policies of a person or
entity,  whether  through the  ownership  of voting  securities,  by contract or
otherwise.

      4.5   PREEMPTIVE RIGHTS.
            -----------------

            A.    Kronos hereby grants HoMedics the preemptive  rights described
      in this  Section 4.5 with regard to all  issuances  by Kronos of shares of
      Kronos Common Stock after the date of this  Agreement  (collectively,  the
      "New  Securities");  PROVIDED,  HOWEVER,  that  "New  Securities"  do  not
      include:

                  1.    securities  issued in connection  with any stock splits,
            stock  dividends  or  other  distribution  payable  pro  rata to all
            holders of Kronos Common Stock;

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

                  3.    any Kronos  Common  Stock  issued  upon the  conversion,
            exercise or exchange of any securities  included in the  calculation
            of the Warrant No. 1 Shares and the Warrant No. 2 Shares.

            B.    If Kronos proposes to offer to sell 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


                                       15


      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.

            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.

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

      The following  events are hereby defined as "defaults" for all purposes of
this Agreement,  whatever the reason for the occurrence thereof and whether such
event  shall be  voluntarily  or  involuntarily  or come about or be effected by
operation of law or pursuant to compliance with any judgment, order or decree of
any court or any order,  rule or regulation of any government or  administrative
body:

      5.1.  DEFAULTS.
            --------

            A.    FAILURE TO PAY. The Borrowers shall fail to pay any principal,
      interest or fee under the Notes, any other  Investment  Documents or other
      indebtedness  to HoMedics  thirty (30) days  following  written  notice by
      HoMedics of either Borrower's failure to pay any such amounts when due, by
      maturity, acceleration or otherwise.

            B.    MISREPRESENTATION.   Any   warranty   or   representation   in
      connection with or contained in this Agreement, the License Agreement, the
      Amended License, or any of the Investment  Documents,  or if any financial
      data or other information now or hereafter  furnished to HoMedics by or on
      behalf of the  Borrowers,  is false or misleading in any material  respect
      when made or deemed made.

            C.    DEFAULT UNDER DOCUMENTS.  Either Borrower shall otherwise fail
      to perform any of its  obligations  or covenants  under,  or shall fail to
      comply  with  any of  the  provision  of:  (1)  this  Agreement;  (2)  the
      Investment Documents,  or (3) the License Agreement,  the Amended License,
      or any other license  arrangement  between  HoMedics and either  Borrower,
      which is not cured  within  thirty (3) days  following  written  notice by
      HoMedics of such failure to perform by either Borrower.

                                       16


            D.    INSOLVENCY/BANKRUPTCY.  Either Borrower  voluntarily  suspends
      transacting  business, or either Borrower generally fails to pay its debts
      as they mature or makes a general assignment for the benefit of creditors;
      or commences any  proceedings  in  bankruptcy,  or for  reorganization  or
      liquidation under the Bankruptcy Code or under any other state, federal or
      other applicable law for the relief of debtors,  or has commenced  against
      it any  proceedings in bankruptcy,  or for  reorganization  or liquidation
      under  the  Bankruptcy  Code or under any other  state,  federal  or other
      applicable  law  for the  relief  of  debtors  which  proceedings  are not
      discharged within sixty (60) days of commencement;  or a receiver, trustee
      or  custodian  is  appointed  for either  Borrower or for any  substantial
      portion of its respective properties or assets.

            E.    CHANGE OF  MANAGEMENT  OR CONTROL.  Kronos shall  experience a
      Change in Control. A "CHANGE IN CONTROL" of Kronos will be deemed to occur
      if: (x) any person  (defined for the  purposes of this  Section  5.1(E) to
      mean any person  within the  meaning  of Section  13(d) of the  Securities
      Exchange  Act of 1934 (the  "EXCHANGE  Act")),  other than  Kronos,  or an
      employee  benefit  plan  established  by the Board of Directors of Kronos,
      acquires,  directly or indirectly,  the beneficial  ownership  (determined
      under Rule 13d-3 of the  regulations  promulgated  by the  Securities  and
      Exchange Commission under Section 13(d) of the Exchange Act) of securities
      issued by Kronos having  thirty  percent (30%) or more of the voting power
      of all of the  voting  securities  issued  by Kronos  in the  election  of
      directors  at the meeting of the holders of voting  securities  to be held
      for such  purpose;  or (y) a  majority  of the  directors  elected  at any
      meeting of the holders of voting securities of Kronos are persons who were
      not nominated for such election by the Board of Directors of Kronos having
      authority in such matters;  or (z) Kronos merges or  consolidates  with or
      transfers substantially all of its assets to another person.

      5.2   REMEDIES.  If an Event of Default exists,  HoMedics may exercise any
right,  power or remedy permitted by law or as set forth in any of the documents
and instruments executed and delivered in connection herewith, including without
limitation,  the Investment  Documents.  Without  limiting the generality of the
foregoing,  the Borrowers  agree to reimburse  HoMedics upon demand for all fees
and expenses  incurred by HoMedics (A) in seeking to collect any amounts owed to
it  (whether  through  formal  or  informal  collection  actions,   workouts  or
otherwise),  in defending the validity or priority of its security interest,  or
in pursuing its rights and remedies under this Agreement; (B) in connection with
any   proceeding   (including,    without   limit,    bankruptcy,    insolvency,
administrative,  appellate,  or probate  proceedings  or any  lawsuit)  in which
HoMedics  at any time is involved  as a result of any  lending  relationship  or
involving  HoMedics and either Borrower;  or (C) incurred by HoMedics during the
continuance of an Event of Default,  which fees and expenses  relate to or would
not have been incurred but for any lending  relationship  involving HoMedics and
either  Borrower.  The fees and expenses  include,  without limit,  court costs,
legal expenses, and reasonable attorneys' fees.

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)
