                                 PROMISSORY NOTE
                                 ---------------

$325,000.00                                                        July 29, 2005

     FOR VALUE RECEIVED, the undersigned, ENVIROCLEAN MANAGEMENT SERVICES, INC.,
a Texas corporation  ("Maker"),  whose address is 17120 N. Dallas Parkway, Suite
235, Dallas, Texas 75248 hereby promises to pay to the order of PARK CITIES BANK
(together  with its  successors  and assigns and any  subsequent  holder of this
Promissory Note, "Payee"), as hereinafter  provided,  the principal sum of THREE
HUNDRED  TWENTY  FIVE  THOUSAND  AND NO/100  DOLLARS  ($325,000.00),  or so much
thereof as may be  advanced by Maker from time to time  hereunder  to or for the
benefit or  account  of Payee,  together  with  interest  thereon at the rate of
interest hereinafter provided, and otherwise in strict accordance with the terms
and provisions hereof.

     1.   Interest.  Interest shall accrue on the principal  balance from day to
day outstanding  hereunder at a rate (the "Applicable Rate") equal to the lesser
of:

          (i)  The Maximum Lawful Rate (as hereinafter defined); or

          (ii) A floating  rate of interest  (the  "Adjustable  Rate") per annum
     equal to the sum of (i) the  Prime  Rate  (defined  below) in effect on the
     date of the  disbursement  of the  initial  advance  under this Note and as
     adjusted  to the Prime Rate in effect on each day  thereafter  and (ii) two
     percent  (2.0%),  commencing on the Advance Date and continuing  thereafter
     until the Maturity Date (defined below).

     The term  "Prime  Rate" as used in this Note and the Loan  Documents  which
secure this Note means the highest  "Prime Rate"  published in the "Money Rates"
section  of The Wall  Street  Journal  from  time to  time.  The  Prime  Rate is
determined  from time to time as a means of  pricing  some  loans and is neither
tied to any external rate of interest or index nor does it  necessarily  reflect
the lowest rate of  interest  actually  charged by the Lender to any  particular
class or category of customers of the Lender.  If the Prime Rate as published in
the "Money  Rates"  section  of The Wall  Street  Journal  ceases to exist or is
discontinued  or no longer  published,  Lender shall have the right,  exercising
reasonable  judgment,  to  substitute  a  comparable  index which is outside the
control  of  Lender.  If  the  Lender  shall  so  substitute  a new  method  for
determining the Prime Rate as aforesaid,  such new method shall become effective
immediately on written  notice to the Borrower.  In the event of an error by The
Wall Street  Journal in publishing  the Prime Rate,  the Prime Rate shall be the
actual Prime Rate, as corrected.

     2.   Payment.  This  Note  shall  be due and  payable,  without  setoff  or
deduction, as follows:

          (i)  Monthly  installments  of accrued but unpaid interest at the then
     applicable  Adjustable Rate, plus principal in an amount necessary to fully
     amortize  the  outstanding  principal  balance  of this Note over a 20 year
     period  commencing  on the  date  hereof  shall be due and  payable  on the
     twenty-ninth  (29th) day of each  month,  beginning  on August 29, 2005 and
     continuing on the same day of each month thereafter (except February,  when
     the payment  shall be due on the 28th)  thereafter  until the Maturity Date
     (as defined below); and

          (ii) The entire  outstanding  principal balance hereof and all accrued
     but unpaid  interest shall be finally due and payable on July 29, 2010 (the
     "Maturity Date").

     All  payments  under  this Note made to Payee at  Payee's  banking  offices
located at 5307 E. Mockingbird Lane, Suite 200, Dallas,  Texas 75206, or at such
other place or manner as the Payee may from time to time  designate  in writing,
without  offset,  in lawful money of the United States of America which shall be
legal  tender in payment of all debts at the time of  payment.  Maker may prepay
all or any  portion of the  principal  of this Note at any time and from time to
time prior to maturity  without premium or penalty,  and interest shall cease to
accrue on any amounts so prepaid,  and any such prepayment of principal shall be
applied in the inverse order of maturity to the last maturing  installment(s) of
principal  under  this  Note.  Any  payment,   whether  a  regularly   scheduled
installment,  a prepayment or  otherwise,  shall be applied first to accrued but
unpaid  interest,  and the  remainder  of such  payment  shall be applied to the
reduction of the outstanding  principal  balance.  Maker hereby agrees to accept
Payee's  calculation of interest payable hereunder absent manifest  mathematical
error. If any payment on this Note shall become due on a Saturday, Sunday or any
other day which is a banking  holiday,  such  payment  shall be made on the next
succeeding  business day which is not a banking  holiday,  and such extension of
time shall in each such case be included in computing interest due hereunder. No
principal amount repaid may be reborrowed.

     3.   Loan   Documents;   Security.   This  Note   evidences,   among  other
indebtedness,  the loan  governed by that  certain  Loan  Agreement of even date
herewith (as modified and amended from time to time, the "Loan  Agreement"),  by
and between  Maker and Payee among others.  Payment  hereof is secured by, among
other  things,  that  certain  Deed of Trust of even date  herewith (as renewed,
extended  and  modified  from time to time,  the "Deed of  Trust"),  executed by
Maker, as grantor,  for the benefit of Payee,  covering certain property located
in Harris  County,  Texas.  Reference is hereby made to said Deed of Trust for a
description  of the  security  and the liens  therein  granted and the rights of
Maker  and  Payee  thereunder.  This  Note,  the Loan  Agreement  and any  other
agreement,   document  or  instrument  governing,   securing,   guaranteeing  or
pertaining  to  the  indebtedness   evidenced  by  this  Note  are  referred  to
collectively herein as the "Loan Documents".

     4.   Default and Remedies.  Upon the occurrence and during the existence of
an "Event of Default"  (herein so  called),  as such term is defined in the Loan
Agreement, Payee shall have the immediate right, at the sole discretion of Payee
and without  notice or demand (i) to declare the entire  unpaid  balance of this
Note and all accrued but unpaid  interest  at once  immediately  due and payable
(and the same shall be at once  immediately  due and payable and the same may be
collected  forthwith),  (ii) to  foreclose  and enforce  all liens and  security
interests  securing  payment hereof,  and (iii) to exercise any of Payee's other
rights, powers,  recourses and remedies under this Note or any of the other Loan
Documents, or at law or in equity.

     5.   Attorney's  Fees and Costs.  If Payee  retains an  attorney-at-law  in
connection with any Event of Default or at maturity or to collect,  enforce,  or
defend this Note or any part hereof, or any of the other Loan Documents,  in any
lawsuit or in any probate, reorganization, bankruptcy or other proceeding, Maker
agrees to pay all costs and expenses of  collection,  including  but not limited
to, Payee's reasonable attorney's fees, whether or not any legal action shall be
instituted.

     6.   Late Charge.  At the option of Payee,  Maker shall pay a "late charge"
in the amount of five (5%) of any installment on this Note when such installment
is not paid within fifteen (15) days following the date such installment is due,
in order to cover  the  additional  expenses  involved  in  handling  delinquent
payments.

     7.   Default Interest Rate. All past due installments of interest shall, if
permitted by applicable law, bear interest at an annual rate equal to the lesser
of the highest lawful rate  permitted by applicable  law or the Applicable  Rate
plus five percent (5%) per annum. During the existence of any default hereunder,
the entire  unpaid  principal  balance  shall bear  interest at the highest rate
permitted by applicable law, including applicable federal or state laws.

     8.   Governing  Law.  This Note  shall be  governed  by, and  construed  in
accordance with, the laws of the State of Texas,  except to the extent such laws
are  preempted by federal  laws,  in which case,  this Note shall be governed by
such  federal  laws,  as  applied  in the  State  of  Texas.  In the  event  the
enforceability  or validity  of any  provision  of this Note or of any  document
evidencing or securing the  indebtedness  represented by this Note is challenged
or questioned,  such  provision  shall be governed by, and shall be construed in
accordance with, whichever applicable federal or Texas law would uphold or would
enforce such challenged or questioned provision.

     9.   General Interest and Usury Provisions.

     (a)  Savings Clause. It is expressly stipulated and agreed to be the intent
of Maker and Payee at all times to comply strictly with the applicable Texas law
governing  the maximum  rate or amount of interest  payable on the  indebtedness
evidenced by this Note and the Related Indebtedness (as hereinafter defined), or
applicable  United  States  federal law to the extent  that it permits  Payee to
contract for, charge, take, reserve or receive a greater amount of interest than
under Texas law. If the applicable law is ever  judicially  interpreted so as to
render  usurious any amount (i)  contracted  for,  charged,  taken,  reserved or
received  pursuant to this Note,  any of the other Loan  Documents  or any other
communication  or  writing  by  or  between  Maker  and  Payee  related  to  the
transaction or  transactions  that are the subject matter of the Loan Documents,
(ii) contracted for, charged,  taken,  reserved or received by reason of Payee's
exercise  of the  option to  accelerate  the  maturity  of this Note  and/or the
Related Indebtedness, o r (iii) Maker will have paid or Payee will have received
by reason of any  voluntary  prepayment by Maker of this Note and/or the Related
Indebtedness,  then it is Maker's  and Payee's  express  intent that all amounts
charged in excess of the Maximum Lawful Rate shall be automatically canceled, ab
initio,  and all  amounts  in  excess of the  Maximum  Lawful  Rate  theretofore
collected  by Payee  shall be  credited  on the  principal  balance of this Note
and/or the Related  Indebtedness (or, if this Note and all Related  Indebtedness
have  been or  would  thereby  be paid in  full,  refunded  to  Maker),  and the
provisions of this Note and the other Loan Documents shall immediately be deemed
reformed  and  the  amounts  thereafter  collectible  hereunder  and  thereunder
reduced,  without the necessity of the  execution of any new document,  so as to

<PAGE>

comply with the applicable laws, but so as to permit the recovery of the fullest
amount otherwise called for hereunder and thereunder; provided, however, if this
Note has been paid in full before the end of the stated term of this Note,  then
Maker and Payee agree that Payee shall,  with reasonable  promptness after Payee
discovers  or is advised by Maker that  interest  was  received  in an amount in
excess of the Maximum Lawful Rate,  either credit such excess  interest  against
this Note and/or any Related  Indebtedness  then owing by Maker to Payee  and/or
refund such excess  interest to Maker.  Maker hereby  agrees that as a condition
precedent to any claim seeking usury penalties against Payee, Maker will provide
written notice to Payee,  advising Payee in reasonable  detail of the nature and
amount of the  violation,  and Payee shall have sixty (60) days after receipt of
such  notice  in which to  correct  such  usury  violation,  if any,  by  either
refunding  such excess  interest  to Maker or  crediting  such  excess  interest
against this Note and/or the Related  Indebtedness then owing by Maker to Payee.
All sums contracted for, charged,  taken,  reserved or received by Payee for the
use,  forbearance  or  detention  of any debt  evidenced by this Note and/or the
Related  Indebtedness  shall,  to the extent  permitted  by  applicable  law, be
amortized, prorated, allocated or spread, using the actuarial method, throughout
the stated term of this Note and/or the Related Indebtedness  (including any and
all renewal and  extension  periods)  until  payment in full so that the rate or
amount of interest on account of this Note and/or the Related  Indebtedness does
not exceed the Maximum Lawful Rate from time to time in effect and applicable to
this Note and/or the Related Indebtedness for so long as debt is outstanding. In
no event shall the  provisions  of Chapter 346 of the Texas  Finance Code (which
regulates  certain  revolving  credit  loan  accounts  and  revolving   triparty
accounts)   apply  to  this  Note  and/or  any  of  the  Related   Indebtedness.
Notwithstanding anything to the contrary contained herein or in any of the other
Loan  Documents,  it is not the intention of Payee to accelerate the maturity of
any interest that has not accrued at the time of such acceleration or to collect
unearned interest at the time of such acceleration.  The terms and provisions of
this  paragraph  shall  control and  supersede  every  other  term,  covenant or
provision contained herein, in any other Loan Document or in any other agreement
between the Maker and Payee.

     (b)  Ceiling  Election.  To the extent that Payee is relying on Chapter 303
of the Texas  Finance Code to determine  the Maximum  Lawful Rate payable on the
Note and/or any other  portion of the Related  Indebtedness,  Payee will utilize
the weekly  ceiling from time to time in effect as provided in such Chapter 303,
as amended.  To the extent United  States  federal law permits Payee to contract
for,  charge,  take,  receive or reserve a greater amount of interest than under
Texas law,  Payee will rely on United States federal law instead of such Chapter
303 for the purpose of determining the Maximum Lawful Rate. Additionally, to the
extent permitted by applicable law now or hereafter in effect, Payee may, at its
option  and from time to time,  utilize  any other  method of  establishing  the
Maximum  Lawful Rate under such  Chapter 303 or under  other  applicable  law by
giving notice,  if required,  to Maker as provided by such applicable law now or
hereafter in effect.

     (c)  Definitions.

          (i)  As used  herein,  the term  "Maximum  Lawful Rate" shall mean the
     maximum  lawful  rate of interest  which may be  contracted  for,  charged,

     of the State of Texas  (or  applicable  United  States  federal  law to the
     extent that such law permits Payee to contract for, charge,  take,  receive
     or reserve a greater amount of interest than under Texas law),  taking into
     account all Charges made in connection  with the  transaction  evidenced by
     this Note and the other Loan Documents.

          (ii) As used herein,  the term "Charges" shall mean all fees,  charges

     under applicable law.

          (iii) As used herein, the term "Related  Indebtedness"  shall mean any
     and all indebtedness paid or payable by Maker to Payee pursuant to the Loan

     Payee  related to the  transaction  or  transactions  that are the  subject
     matter of the Loan Documents,  except such indebtedness which has been paid
     or is payable by Maker to Payee under this Note.

               for each of the Products shall initially be determined as cost of

               COMPANY may modify the Distributor's Cost at any time upon not
               less than ninety (90) days' prior notice to Distributor. All
               prices are F.O.B. COMPANY, Alpharetta, GA. United States of

               transportation costs, handling, set-up costs, customs duties,
               customs surcharges, value added tax (VAT) and any other

               shall be in United States Dollars; shall be made within thirty
               (30) days of the delivery of the Products to the destination in
               the Territory; and shall be sent to COMPANY via wire transfer as
               follows:

                    Wire instructions to be sent under separate cover

          (c)  Minimum Quantity. The Distributor shall be subject to Minimum
               Purchase Requirements (as defined below). During each contract
               year throughout the term of this Agreement, the Distributor shall
               purchase from COMPANY not less than the minimum purchase
               requirements of each of the Products which are agreed to by the
               Parties following the review of the Market Study and Forecast in
               accordance with Section 2.3(e) of this Agreement (the "Minimum
               Purchase Requirements"). If COMPANY discontinues selling any of
               the Products or the Parties otherwise mutually agree to delete
               any of the Products from the Minimum Purchase Requirements, the
               amount of the discontinued or deleted Product that was to be
               distributed shall be deducted from the total Minimum Purchase
               Requirements. The Distributor: (i) acknowledges that the Minimum
               Purchase Requirements are a material inducement for COMPANY to
               enter into this Agreement and that such Minimum Purchase
               Requirements have been determined jointly by COMPANY and
               Distributor; and (ii) hereby represents to COMPANY that it is
               capable of achieving such Minimum Purchase Requirements. If at
               any time Distributor has failed to meet its Minimum Purchase
               Requirements with respect to a Product for the immediately
               preceding calendar year, COMPANY shall have the right at any time
               within ninety (90) days thereafter, to terminate this Agreement
               or, alternatively, to terminate Distributor's right to distribute
               the Product in any country or geographic region (e.g., Hong Kong
               Special Administrative Region of the PRC, the Republic of China
               (Taiwan), or Singapore) within the Territory with respect to
               which Minimum Purchase Requirements have not been met.

          (d)  Arbitration for Determination of Minimum Purchase Requirements.
               In the event the Parties are unable to reach agreement under
               Section 2.3(e) as to Minimum Purchase Requirements, either Party
               shall have the right to notify the other Party in writing

                                       2
<PAGE>

               that it desires such determination to be settled by arbitration
               before one arbitrator mutually agreed upon by the Parties. In the
               event the Parties are unable to agree upon an arbitrator within
               thirty (30) days of such notice, the arbitrator shall be selected
               in accordance with the rules of the American Arbitration
               Association ("AAA"), provided that any arbitrator so selected
               shall have performed at least two arbitrations in the
               biotechnology industry for a state or federal court or a
               financial institution within the last two years. The arbitration
               shall be conducted in English in Los Angeles, California unless
               both Parties consent to a different location. Within thirty (30)
               days after the appointment of the arbitrator, each of the Parties
               shall present to the arbitrator its written proposal setting
               forth what it believes to be appropriate Minimum Purchase
               Requirements, together with its reasoning therefore. After
               receipt of each Party's written presentation, the arbitrator
               shall deliver a copy of each Party's presentation to the other
               Party and to provide the other Party with thirty (30) days to
               submit a written rebuttal to the presentation. The arbitrator
               shall have the right, but shall not be required, to require oral
               testimony. The arbitrator shall reach a final determination of
               Minimum Purchase Requirements by selecting either the proposal
               initially submitted by the Company or the proposal initially
               submitted by Distributor. The arbitrator shall have no authority
               to reach any other determination. The decision of the arbitrator
               shall be final and binding upon all Parties. All fees and
               disbursements of the AAA and the arbitrator shall be borne
               equally between the Parties.

               plan and network for the Product in the Territory and shall use

               price and minimum purchase quantities of comparable medical
               devices sold and purchased in the Territory. If the Parties
               cannot agree on such prices and minimum purchase quantities
               within such period, then the Parties shall submit the matter to
               arbitration to determine such prices and minimum purchase
               quantities in accordance with Section 2.2(d) of this Agreement
               with instructions to the arbitrators to decide the matter within
               ninety (90) days.

          (f)  any information derived from any of the foregoing that is treated
               as confidential.

5A.  Use of Confidential Information.

     (a)  Restricted Party shall:

          (i) retain in confidence all Confidential Information in trust for the
benefit of Disclosing Party, and not for its own benefit or for the benefit of
others without the express written consent of Disclosing Party;

          (ii) use Confidential Information obtained from Disclosing Party only
for the purpose of performing its obligations under this Agreement and for no
other purpose whatsoever; and

          (iii) not disclose, directly or indirectly, to any person or third
party (other than permitted agents and employees under Section 5A(c)) any
Confidential Information obtained from Disclosing Party under this Agreement
unless:

               (1) Restricted Party has obtained the approval in writing of
          Disclosing Party;

                                       8
<PAGE>

               (2) Restricted Party is making the disclosure to a government
          body and the disclosure is required to be made under the laws
          applicable to Restricted Party or Disclosing Party or

               (3) Restricted Party is making the disclosure strictly in
          accordance with an order of a competent court of law.

          (iv) not make use of Confidential Information except for the benefit
of Disclosing Party as solely determined by Disclosing Party; and

          (v) not use the Confidential Information in any manner to the
competitive, economic or other detriment of Disclosing Party.

     (b) Restricted Party shall take all reasonable precautions to preserve the
confidentiality of the Confidential Information including, without limitation,
standards for protection of proprietary and confidential information and
intellectual property that are commonly applied by other comparable companies in
the biotechnology industry as well as such precautions as Restricted Party
usually observes in order to protect its own Confidential Information. Without
limiting the foregoing, in the event that Restricted Party receives a request to
disclose all or any part of the Confidential Information under the terms of a
valid and effective subpoena or other order issued by a court having
jurisdiction or by a governmental body and intends to disclose any Confidential
Information under Section 5A(a)(iii)(2) or (3), then, unless precluded by laws
applicable to Restricted Party, Restricted Party shall (i) immediately provide
written notice of the existence, terms and circumstances surrounding such
request and Restricted Party's intent to disclose, so that Disclosing Party may
seek an appropriate protective order or other remedy and/or waive Restricted
Party's compliance with the provisions of this Agreement, to Disclosing Party,
(ii) exercise reasonable efforts to obtain an order or other reliable assurance
that confidential treatment will be accorded to such of the disclosed
Confidential Information which the Company so designates and (iii) wait the
maximum amount of time permitted by such government body or court of law before
making such disclosure.

     (c) Restricted Party further agrees to exercise appropriate caution to
maintain the secrecy of the Confidential Information, including (i) limiting
disclosure and access to the Confidential Information only to its agents and
employees who require access to the Confidential Information for the purpose of
this Agreement, and who have signed a Declaration With Respect to Confidential
Information in the form attached as Exhibit A to this Agreement (copies of which
shall be made available to Disclosing Party upon request); and only for the
periods of their employment or other relationship with Restricted Party, and
(ii) storage of the Confidential Information in a secure location accessible
only to the individuals to whom access is permitted under subparagraph (i) of
Section 5A(c) of this Agreement.

     (d) At the expiration of the term of this Agreement, including upon its
early termination, Restricted Party shall, at the discretion of Disclosing
Party, destroy or return to Disclosing Party all of the documents containing
Confidential Information that have been supplied to it during the course of this
Agreement. In no case may any copy of documents containing Confidential
Information be preserved by Restricted Party.

     (e) Disclosing Party has developed or purchased, or will develop or
purchase, its Confidential Information at substantial expense in a market in
which they face intense competitive pressure, and Disclosing Party has kept and
will keep secret its Confidential Information. Disclosing Party will suffer
immediate and irreparable harm, loss and damage not adequately compensable by
monetary damages if Restricted Party violates any of the provisions of Section
5A of this Agreement.

     (f) In case of the discovery of unauthorized disclosure or use of any
Confidential Information, Restricted Party shall promptly inform Disclosing
Party and immediately take all appropriate measures to prevent further
unauthorized disclosure or use and use its best efforts, including reasonable
legal means, to stop any further unauthorized use or disclosure of Confidential
Information and to secure the return thereof.

                                       9

     (g) Restricted Party agrees not to reproduce or copy by any means
Confidential Information, except with the prior written consent of Disclosing
Party or for disclosure as permitted under this Agreement. All Confidential
Information, and any copies of extract thereof, shall be returned by Restricted
Party to Disclosing Party either at the end of review by Restricted Party or
upon demand by Disclosing Party.

     (h) Restricted Party represents that it deals with confidential and
proprietary information in its business, and represents and agrees that, with
respect to the Confidential Information disclosed pursuant to this Agreement,
that it will implement and institute the procedure for storing and maintaining
the confidentiality of Confidential Information as set forth in Sections 5A(b)
and 5A (c) of this Agreement. Restricted Party shall not remove any proprietary
rights legend from materials disclosing Confidential Information and shall, upon
the Disclosing Party's reasonable request, add any proprietary rights legend to
materials disclosing or embodying Confidential Information. Any copies of the
Confidential Information that are made shall be marked "confidential" or
"proprietary" by Restricted Party.

     (i) Restricted Party acknowledges that Confidential Information may still
be under development, or may be incomplete, and that such information may relate
to products that are under development or are planned for development. In
disclosing the Confidential Information, Disclosing Party makes no
representation or warranty, either express or implied, as to the adequacy,
accuracy, sufficiency or freedom of the Confidential Information from defect of
any kind, including freedom from patent or trademark infringement. Disclosing
Party accepts no responsibility for any expenses, losses or action undertaken or
not undertaken by Restricted Party as a result of Restricted Party's receipt or
use of Confidential Information.

     (j) Restricted Party agrees to act in good faith so as not to harm the
business or personal reputation of a Disclosing Party or its affiliates, and
shall not defame, disparage or publicly criticize the services, business,
integrity or personal or professional reputation of Disclosing Party or its
affiliates.

     (k) Other than as expressly stated herein, Disclosing Party grants no
license to Restricted Party under any copyrights, patents, trademarks, trade
secrets or other proprietary rights to use or reuse Confidential Information.

5B.  Protection of Proprietary Technology.

(a) Use of Marks or Patents; Limitations with respect to Licensing, if any. To
the extent that Distributor or any of its permitted assigns under Section 2.4 of
this Agreement at any time is explicitly authorized in writing by the COMPANY to
use any means any trademarks, trade names, logos or designs of COMPANY,
including without limitation the names "BIOFIELD", "BIOFIELD(R)" and
"BIOFIELD(R) Breast Cancer Diagnostic System" (the "Marks") or any patents,
whether issued or pending in any jurisdiction, of COMPANY (the "Patents"):

     (i) all rights resulting from Distributor's use of any Mark or Patent shall
inure to the sole and exclusive benefit of COMPANY, its affiliates and/or their
respective licensors (and not Distributor), and Distributor's use of any Mark or
Patent shall be in a form and manner satisfactory to the Company and in
compliance with any applicable country of origin labeling requirements;

     (ii) such authorization shall be deemed a non-exclusive, non-transferable,
restricted "at-will" license to use the Marks or Patents solely in connection
with the performance of Distributor's duties as set forth in this Agreement;

     (iii) Distributor acknowledges that the license of the Marks or Patents
shall be limited to COMPANY's rights to use the Marks or Patents and shall not
in any way be deemed to represent or warrant that any use of the Marks or
Patents shall not infringe or be alleged to infringe upon the rights of other
third parties; and

                                       10
<PAGE>

     (iv) all rights granted hereunder shall terminate immediately in the event
this Agreement is terminated.

(b) Reservation of Rights. At all times, irrespective of whether or not any
Marks or Patents are licensed to Distributor or its permitted assigns under
Section 2.4 of this Agreement, COMPANY retains all rights not expressly granted
by it under this Agreement. Distributor expressly disclaims any right, title or
interest (other than any license that COMPANY may grant to the Distributor at
COMPANY`s sole discretion) in the Marks or Patents or any derivative thereof. No
other rights of Distributor to use the Marks or Patents shall be implied other
than as set forth in this Agreement. Except as expressly set forth herein, no
entities affiliated with Distributor other than Distributor shall have any
rights to use the Marks or Patents and no rights to such Marks or Patents shall
be implied. Distributor shall not use the Marks or Patents in any manner
whatsoever anywhere in the world other than as expressly authorized by this
Agreement. Except as licensed hereunder, Distributor shall not use any Marks,
trademark (including any service mark or trade Marks) confusingly similar to
"BIOFIELD", "BIOFIELD(R)" and "BIOFIELD(R) Breast Cancer Diagnostic System."

(c) Ownership. Distributor shall not anywhere in the world challenge the
validity of the Marks or Patents, the Confidential Information, or COMPANY's
ownership of the Marks, Patents or COMPANY's Confidential Information, or the
enforceability of COMPANY's rights therein, or oppose any registration or
application for registration (made by or under the authorization of COMPANY or
any of its affiliates) of the Marks or Patents or COMPANY's intellectual
property rights with respect to its Confidential Information. All uses of the
Marks or Patents and Confidential Information by Distributor shall inure to the
benefit of COMPANY. In addition, Distributor shall not knowingly take or omit to
take, or authorize the taking or omission of, any action that could reasonably
be expected to dilute or adversely affect the Marks, COMPANY's Confidential
Information, or COMPANY's ownership thereof or the validity, enforceability,
registration or application for registration thereof, or any related goodwill.
Distributor shall do such further acts and things, and to execute and deliver
such additional conveyances, assignments, agreements and instruments, reasonably
required by COMPANY to assure and confirm COMPANY's ownership rights in the
Marks, Patents and COMPANY's Confidential Information and its rights and
remedies relating to the Marks, Patents and COMPANY's Confidential Information
under this Agreement. If requested by COMPANY, Distributor may cause to be
registered the relevant Patents, Marks, and other intellectual property of the
COMPANY with the applicable government intellectual property agencies in the
Territory in COMPANY'S sole name. Any devices or sensors associated with the
Products shall distinctly and visibly bear the name of COMPANY acknowledging the
COMPANY's exclusive ownership of all intellectual property rights associated
with the Products, which shall not be removed by Distributor, its affiliates,
agents or their respective assigns.

5. Press Release and Announcements. The Parties agree that no public release or
announcement concerning the transactions contemplated hereby shall be issued or
made by or on behalf of any Party without the prior consent of the other Party,
except that either Party may, after consultation with counsel, make
announcements that such Party reasonably may determine are necessary to comply
with applicable law. COMPANY acknowledges and agree that Distributor may be
required to announce the terms of this Agreement and make publicly available
this Agreement and that no breach shall be deemed to result there from.
Notwithstanding the foregoing, the Parties cooperate to prepare a joint press
release to be issued in connection with the execution of this Agreement. The
Parties further agree that each shall have the right to display the other logo
on their respective web sites.

6.   Indemnification.

     6.1  Indemnification. Each Party (the "Indemnifying Party") will defend,
          indemnify, and hold the other Party, its officers and directors,
          shareholders, and each of its and their successors and permitted
          assigns (the "Indemnified Parties"), harmless from and against any and
          all liabilities, judgments, losses, actual damages, costs, and
          expenses (including without limitation reasonable attorneys' and
          experts' fees) which any or all of them may hereafter incur themselves
          or pay out to another by reason of any claim, suit or proceeding
          brought by a

                                       11
<PAGE>

          third party, at law or in equity, that arises out of or relates to
          material breach of any representation, warranty, covenant, obligation
          or other provision of this Agreement by the Indemnifying Party, except
          to the extent caused by the gross negligence or willful misconduct of
          an Indemnified Party.

     6.2  Exclusion of Consequential Damages. NOTWITHSTANDING ANYTHING TO THE
          CONTRARY CONTAINED IN THIS AGREEMENT, NEITHER PARTY SHALL, UNDER ANY
          CIRCUMSTANCES, BE LIABLE TO THE OTHER PARTY FOR LOST PROFITS,
          CONSEQUENTIAL, INCIDENTAL, SPECIAL, PUNITIVE, OR INDIRECT DAMAGES
          ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS
          CONTEMPLATED HEREUNDER, EVEN IF THE PARTY HAS BEEN APPRISED OF THE
          LIKELIHOOD OF SUCH DAMAGES, EXCEPT FOR ANY BREACH OF ANY
          REPRESENTATIONS, WARRANTIES OR COVENANTS SET FORTH IN SECTIONS 5, 5A
          and 5B OF THIS AGREEMENT.

7.   Miscellaneous.

          and any purported such assignment without such consent shall be void.
          For purposes of this Section 8.2, a merger involving a Party shall be
          deemed to result in an assignment of this Agreement to the surviving
          entity in the merger, regardless of whether the Party is the surviving
          entity or merging entity to such a merger.

     7.4  Severability. If any term or provision of this Agreement, or the
          application thereof to any person or circumstance, shall to any extent
          be contrary to any applicable law or regulation or otherwise invalid
          or unenforceable, the remainder of this Agreement or the application
          of such term or provision to persons or circumstances other than those
          as to which it is contrary, invalid or unenforceable shall be affected
          thereby and, to the extent consistent with the overall intent of this
          Agreement taken as a whole, shall be enforced to the fullest extent
          permitted by applicable law and regulation.

     7.5  Governing Law. This Agreement and any Project Documents, and any
          dispute relating to the Agreement or any Project Documents, will be
          governed by the laws of Delaware except as specifically provided in
          such documents, without regard to principles of conflict of laws. The
          United Nations Convention on Contracts for the International Sale of
          Goods shall not apply to this Agreement or any other document
          contemplated under the Project.

     7.6  Enforceability; Injunctive Relief. Distributor, on behalf of itself
          and on behalf of any permitted assigns pursuant to Section 2.4, agrees
          that the representations and warranties, covenants and agreements
          contained in this Agreement are of the essence of this Agreement; that
          such covenants are reasonable and necessary to protect and preserve
          the interests and properties of COMPANY and their respective
          businesses; that irreparable loss and damage will be suffered by
          COMPANY and its affiliates should Distributor breach any such
          covenants and agreements; that given the unique nature of COMPANY's
          business, such loss and damage would be suffered by COMPANY,
          regardless of where a breach of such covenants and agreements occurs;
          that each of such covenants and agreements are separate, distinct and
          severable not only from the other of such covenants and agreements but
          also from the other and remaining provisions of this Agreement; that
          the enforceability or breach of any such covenants or agreements shall
          not affect the validity or enforceability of any other such covenants
          or agreements or any other provision or provisions of this Agreement;
          and that, in addition to other remedies available to it, COMPANY shall
          be entitled to both temporary and permanent injunction, without the
          posting of any bond or other security, and any other rights and
          remedies it may have, at law or in equity, to prevent a breach or
          contemplated breach by Distributor of any of such representations and
          warranties, covenants or agreements. Notwithstanding anything to the
          contrary, in the case of a breach of the provisions of Sections 5, 5A
          and 5B hereof, the affected Party or Parties shall have the right to
          seek the remedy of specific performance in any court of competent
          jurisdiction, it being understood that such remedy shall be in
          addition to and not in limitation of any other remedy of such affected
          Party or Parties.

                                       13
<PAGE>

     7.7  Submission to Forum/Jurisdiction. Unless otherwise explicitly set
          forth in this Agreement, the Parties explicitly and irrevocably
          consent and submit to the personal jurisdiction of the United States
          District Court for the Southern District of California (including any
          mediation procedure before a United States Magistrate Judge).

     7.8  Survival. All warranties, representations, obligations and covenants
          of the Parties hereto shall survive the execution and delivery of this
          Agreement and shall, notwithstanding the execution and delivery of
          this Agreement, continue in full force and effect. The provisions of
          Section 5, 5A and 5B of this Agreement shall forever survive the
          expiration or termination of this Agreement.

     7.9  Non-Waiver. Any failure on the part of a Party to enforce at any time
          or for any period of time any of the provisions of this Agreement
          shall not be deemed or construed to be a waiver of such provisions or
          of any right of such Party thereafter to enforce each and every such
          provision on any succeeding occasion or breach thereof. No waiver of
          any provision of this Agreement or any remedy at law or equity will be
          deemed a waiver of any other provisions of this Agreement or any other
          remedy. Nor will any waiver be deemed a continuing waiver for future
          occurrences. Any waiver must be in writing and signed by the Party
          against whom the waiver is sought to be enforced.

     7.10 Force Majeure. Except as otherwise explicitly stated in this
          Agreement, any delays in performance by any Party under this Agreement
          shall not be considered a breach of this Agreement if and to the
          extent caused by occurrences beyond the reasonable control of the
          Party affected, including but not limited to acts of God, embargoes,
          governmental restrictions, fire, flood, explosion, earthquake,
          hurricanes, storms, tornadoes, riots, wars, civil disorder, failure of
          public utilities or common carriers, labor disturbances, rebellion or
          Sabotage, nationalization, or eminent domain. The Party suffering such
          occurrence shall notify the other Party as soon as practicable of such
          inability and of the period for which such inability is expected to
          continue, and any time for performance hereunder shall be extended by
          the actual time of delay caused by the occurrence; provided, that the
          Party suffering such occurrence uses commercially reasonable efforts
          to mitigate any damages incurred by the other Party. Upon cessation of
          the cause or causes for any such failure or delay, performance of this
          Agreement shall be resumed.

     7.11 Cumulative Rights. Except as herein expressly provided, the rights,
          powers and remedies hereunder shall be in addition to, and not in
          limitation of, all rights, powers and remedies provided at applicable
          law or in equity, or under any other agreement between the Parties,
          and all of such rights, powers and remedies shall be cumulative, and
          may be exercised successively or cumulatively.

     7.12 Counterparts. This Agreement may be executed in any one or more
          counterparts, each of which shall constitute an original, no other
          counterpart needing to be produced, and all of which, when taken
          together, shall constitute but one and the same instrument. If this
          Agreement is signed and transmitted by facsimile machine, the
          signature of any party on such Agreement transmitted by facsimile
          machine shall be considered, and have the same force and effect, as an
          original document.
