restrictions imposed by Company, and without any liability to Company therefore.
The  Independent  Consultants  are intended as third-party beneficiaries of this
provision  as  to  their  ability  to freely enter into an agreement with Buyer.

3.     PURCHASE  PRICE  -  PAYMENT

     3.1.     Purchase  Price.
              ---------------

          The  purchase  price  (the  "Purchase Price") for the Purchased Assets
shall be the payment by Buyer to Loch of the shares of Buyer's Common Stock, par
value  $0.001 per share, in the amount set forth below and payable in accordance
herewith:

     3.2.     Payment  of  Purchase  Price.
              ----------------------------

          At  the  Closing  (as  that  term is hereinafter defined), Buyer shall
deliver to Loch 35,000,000 shares of Buyer's Restricted Common Stock.  Buyer had
previously  delivered  to  Loch  13,000,000  shares of Buyer's Restricted Common
Stock,  which  is  affirmed  by  Buyer and Company to be included in the overall
consideration  received  by  Company.  The  35,000,000  and 13,000,000 shares of
Buyer's  Restricted  Common  Stock  are  collectively  referred  to  as  the
"Shareholders  Shares".  In addition at the Closing, Buyer shall deliver to Loch
13,000,000  shares  of  Buyer's  Restricted Common Stock ("Loch's Shares").  The
61,000,000  shares being collectively called the "Loch and Shareholders Shares".

          The  Shareholders Shares shall be made available to the transfer agent
for  distribution  to  the  Loch  shareholders  on  a one for ten pro-rata basis
described below as soon as practical.  If the delivery to the transfer agent has
not  occurred  by  October  1,  2001,  the voting rights of these shares, unless
waived  by  Buyer  at  its  discretion from time to time, shall be assigned in a
proxy to the Board of Directors of Buyer until such shares have been distributed
to  shareholders of Loch on a one for ten pro-rata basis described below.  After
October  1,  2001,  if  the Shareholders Shares have not been distributed to the
Loch  shareholders  and  it  is  determined  that  it  is  legally impossible or
economically  impractical  to  do  so,  the  voting proxy for those shares shall
remain  with  the  Board  of  Directors  of  CDEX  until  those shares are sold,
transferred  or assigned to parties not controlled in any fashion by Loch or its
Officers  or  Directors.  If  the number of shares of Shareholder Shares are not
sufficient  to  accomplish a distribution of one share of Buyer's stock for each
ten  shares  of  Loch  stock, then shares shall be taken from the Loch Shares to
accomplish  that  objective.  If  the  number  of  shares of Shareholders Shares
exceeds  the number of shares required to accomplish a one for ten distribution,
such  excess  shall  be  added  to  the  Loch  Shares.


                                        3

          In  addition, Buyer shall provide a combined total of 8,325,000 shares
of Buyer's Restricted Common Stock to those listed in Exhibit B (the "Obligation
Stock"),  as  directed  by  the  Company  as part of the compensation for assets
transferred under this Agreement.  The Obligation Stock is provided to discharge
certain  loans  and other obligations of the Company related to the Business and
Purchased Assets, to obtain a release of any lien or claim of whatever nature to
the  technology  by such persons who had provided funds, property or services in
connection with the development of the technology, Business and Purchased Asset,
and  to  acquire  the  entire  interest,  if  any  (including but not limited to
ownership  percentage  and  royalty  rights) in the Business or Purchased Assets
originally acquired by Coldwater Capital, LLC and its affiliates.  Buyer did not
and was not required to review the underlying bases for these payments of stock,
other  than  to understand that Company warrants that the payments are necessary
and  adequate  to  secure  clear  and  unencumbered  title  (including  complete
ownership interest with no royalty rights) to the Business and Purchased Assets.
Company  shall  indemnify  Buyer  against  all  claims  to  the  contrary.

          Buyer  and  Loch  shall  make  every  effort  to  complete  the prompt
registration  of  these  shares  (the  Loch  and  Shareholders  Shares  and  the
Obligation  Stock) as soon as practical and pursuant to appropriate filings with
the  Securities and Exchange Commission (the "SEC").  The Loch  Shares are to be
used  by Loch Harris for the benefit of Loch Harris as it sees fit.  However, it
is agreed that as long as Loch owns these Loch Shares the voting rights of these
shares  shall  be  assigned  in  a  proxy  to  the  Board of Directors of Buyer.
Further,  the voting rights of all stock provided to any of the current Board of
Directors  of  Loch  or  persons or parties under their control pursuant to this
Agreement  shall be assigned in a proxy to the Board of Directors of Buyer until
the  stock  is sold, transferred, assigned or conveyed to persons or parties not
controlled  by  such  Board  Member.  Applicable restrictions shall be placed on
these  stock  certificates  to this effect.  Loch agrees to comply strictly with
all  applicable  federal  and  state laws, rules and regulations relating to the
Shares. Loch shall provide and deliver to Buyer all information, certifications,
and  other  documentation  as  may  be  requested  by  Buyer  as part of Buyer's
compliance  with  any  applicable  laws and regulations relating to the issuance
and/or  registration  of  any of the Shares. All certificates for shares of CDEX
prior  to  registration  by the SEC shall  bear an appropriate legend indicating
the  restriction. Filing Costs.  Company shall reimburse Buyer for all costs and
                  -------------
expenses  relating  to the preparation, filing and processing of a statements to
secure  registration  of  the Registered Shares, as may be applicable, including
but not limited to filing fees, attorneys' fees, accountants' fees, and printing
expenses,  except  that  Buyer  shall  be  responsible  for  providing financial
auditing  of  Buyer.

     3.3.   Prorations.  The  parties  shall  make  such  prorations, if any, as
            ----------
of  the Closing Date hereunder as shall be normally adjusted in connections with
similar transactions, with Company liable to the extent such items relate to any
time  period up to and including the Closing Date and Buyer liable to the extent

other  form  of  business  organization  which  is  so  engaged;

               (ii)     consult  with,  advise  or assist in any way, whether or
not  for  consideration,  any  corporation,  partnership, firm or other business
organization  which  is  now or becomes a competitor of Buyer in any aspect with
respect  to the Business or Purchased Assets which Buyer is acquiring hereunder,
including,  but  not limited to, advertising or otherwise endorsing the products
of  any  such  competitor;  soliciting  customers  or  otherwise  serving  as an
intermediary  for any such competitor; loaning money or rendering any other form
of  financial  assistance  to or engaging in any form of business transaction on
other  than  an  arms'  length  basis  with  any  such  competitor;

               (iii)     offer  employment  to  any  employee  of  the Business,
without  the  prior  written  consent  of  Buyer;  or

               (iv)     engage  in any practice the purpose of which is to evade
the  provisions  of  this  covenant  not  to  compete or to commit any act which
adversely  affects  the  Business,  Purchased  Assets  or  Assumed  Liabilities;

     provided,  however,  that  except  as  provided  for  in this Agreement the
foregoing  shall  not prohibit the Company's ownership of securities of Buyer or
of any corporations which are listed on a national securities exchange or traded
in  the  national over-the-counter market in an amount which shall not exceed 5%
of  the  outstanding shares of any such corporation.  The parties agree that the
geographic  scope  of  this covenant not to compete shall extend worldwide.  The
parties  agree  that  Buyer may sell, assign or otherwise transfer this covenant
not  to compete, in whole or in part, to any person, corporation, firm or entity
that  purchases  all  or  part  of the Business or the Purchased Assets.  In the
event  a  court of competent jurisdiction determines that the provisions of this
covenant not to compete are excessively broad as to duration, geographical scope
or  activity,  it is expressly agreed that this covenant not to compete shall be
construed  so  that  the  remaining  provisions shall not be affected, but shall
remain  in  full  force  and effect, and any such over broad provisions shall be
deemed,  without  further  action  on  the  part  of any person, to be modified,
amended  and/or  limited,  but  only  to the extent necessary to render the same
valid  and  enforceable  in  such  jurisdiction.

          6.2.2.     Covenant of Confidentiality.  Company shall not at any time
                     ---------------------------
subsequent  to the Closing, except as explicitly requested by Buyer, (i) use for
any  purpose,  (ii) disclose to any person, expressly including any of the Blair
Affiliates  or  to  any  Independent Contractor, or (iii) keep or make copies of
documents,  tapes,  discs  or programs containing, any Confidential Information.
For  purposes hereof, "Confidential Information" shall mean and include, without
limitation, all Trade Rights, trade secrets, confidential business or commercial
information, business plans, marketing strategies, customer lists, vendor lists,
technical  information,  know-how,  inventions, patents, discoveries (whether or
not  patentable),  copyrights,  trademarks,  service  marks,  techniques,  data,


                                        8

systems,  methods,  processes,  improvements,  developments,  enhancements,  and
modifications,  and  other  proprietary  rights,  whether oral or written, or in
recorded  form,  tangible or intangible, that relate in any way or manner to, or
arise  out  of,  the  Business  and  the  Purchased  Assets.  The  Confidential
Information  shall  also  include  (i)  all  right,  title  and  interest to the
Confidential  Information  arising  under  any laws of any country, and (ii) all
right,  title  and interest in all causes of action relating to the Confidential
Information  arising under the patent, copyright, trademark, service mark, trade
secret,  or other laws of any jurisdiction, which causes of action have not been
asserted  as  of  the Effective Date, that have not previously been disclosed to
the  public directly by Company. The obligations of Company with respect to this
Section  6.2.2  shall  not  apply  to  Confidential  Information:

               (i)     which  at  the  time  of  disclosure  is,  or  thereafter
becomes,  available  to  the  trade or the public without restriction other than
through  the  fault,  negligence,  or  other  acts  of  Company;  or

               (ii)     which  is lawfully and in good faith obtained by Company
from  an  independent  third party without breach of this Agreement, as shown by
documentation  sufficient  to  establish  the  third  party  as  a source of the
Confidential  Information,  and not obtained by the third party from Buyer or by
unlawful  or  improper  means;  or

          Notwithstanding  the  above,  however, Company and Buyer further agree
that  individual  elements  of  the  Confidential  Information  may be or become
available  to  the  general public or a third party through no fault of Company,
but  that  such availability of individual elements of knowledge may not produce
cognizant  appreciation of the value of elements of knowledge and may not render
known  an  integrated  package  of  information  having  the  value  of  Buyer's
integrated  package  of  know-how with its various parameters already reconciled
and  optimized in substantial part. Accordingly, Company understands that public
availability, or the availability from a third party, of the individual parts of
the  Confidential  Information does not release its obligation of confidence for
Confidential  Information  that  is  not  already  publicly  available. Further,
Company  will  not  be  permitted  to  justify  disregard  of the obligations of
confidence  by  use  of the Confidential Information or parts thereof to guide a
search  to  piece  together  a  series  of  items  of knowledge from unconnected
sources,  fitting  them  together  by  use  of  Buyer's  package of Confidential
Information  to  make a showing of nonsecrecy of such information. The foregoing
provisions  of  this  Section  6.2.3  notwithstanding, Company shall not be more
burdened  against  use of information from public sources or third party sources
than a third party competitor would be, had it not received disclosure of either
the Confidential Information or the value of the Confidential Information or any
of  its parts, and had it not had its interest therein sponsored or initiated by
knowledge  of  the  Confidential  Information  or any part thereof or its value.
Accordingly,  subject to the restrictions set forth herein, Company remains free
to  act on and use available information from public sources or from third party
sources  when  and to the extent a competitor of Buyer, otherwise disinterested,
would  in  the natural course of business learn of, appreciate the value of, and
use  such  public  source  or  third  party  source  information  without having
responded  to  initiative or interest suggested by knowledge of the Confidential
Information,  its  parts  or  the  value  thereof.

          6.2.3.     Equitable  Relief  for Violations.  Company agrees that the
                     ---------------------------------
provisions and restrictions contained in this Article 6 are necessary to protect
the  legitimate continuing interests of Buyer in acquiring the Purchased Assets,


                                        9

and  that any violation or breach of these provisions will result in irreparable
injury  to  Buyer  for  which  a  remedy at law would be inadequate and that, in
addition to any relief at law which may be available to Buyer for such violation
or  breach  and  regardless  of any other provision contained in this Agreement,
Buyer  shall be entitled to injunctive and other equitable relief as a court may
grant  after  considering the intent of this Article 6, without the necessity of
posting  bond.

     6.3.     Use  of  Name.  Following  the  Closing,  neither  Company nor any
              -------------
Affiliate shall, without the prior written consent of Buyer, make any use of the
names  "Chemical  Detection  Technology,"  "Chemical  Detection  Technology
Excellence",  "CDEX", "ChemTech" or any other names confusingly similar thereto,
except  as  may  be  necessary  for  Company to pay its liabilities, prepare tax
returns  and  other reports, and to otherwise wind up and conclude its operation
of  the  Business.

7.     INDEMNIFICATION

     7.1.     By  Company.  Subject  to the terms and conditions of this Article
              -----------
7,  Company  hereby  agrees  to  indemnify,  defend  and hold harmless Buyer and
Buyer's  affiliates  from and against all Claims asserted against, resulting to,
imposed upon, or incurred by Buyer, Buyer's affiliates, or the Purchased Assets,
directly  or  indirectly, by reason of, arising out of or resulting from (a) the
inaccuracy  or  breach of any representation or warranty of Company contained in
or  made pursuant to this Agreement (regardless of whether such breach is deemed
"material");  (b)  the  breach  of  any  covenant  of  Company contained in this
Agreement  (regardless  of whether such breach is deemed "material"); or (c) any
Claim of or against Company, the Purchased Assets or the Business resulting from
actions  prior  to  closing.  As  used in this Agreement, the term "Claim" shall
include  (i)  all  Liabilities;  (ii)  all  losses,  damages (including, without
limitation,  consequential  damages),  judgments, awards, settlements, costs and
expenses  (including,  without  limitation,  interest  (including  prejudgment
interest in any litigated matter), penalties, court costs and attorneys fees and
expenses),  whether  arising  from  or  related  to a Liability or Litigation or
otherwise;  and  (iii)  all  demands,  claims,  actions, costs of investigation,
causes  of  action,  proceedings  and  assessments,  whether  or  not ultimately
determined  to  be  valid, and whether arising from or related to a Liability or
Litigation  or  otherwise.

     7.2.     By  Buyer.  Subject to the terms and conditions of this Article 7,
              ---------
Buyer  hereby  agrees  to  indemnify,  defend  and  hold  harmless  Company, its
directors,  officers,  employees  and  controlling persons, from and against all
Claims  asserted  against,  resulting  to,  imposed upon or incurred by any such
person,  directly  or  indirectly,  by  reason  of  or  resulting  from  (a) the
inaccuracy  or breach of any representation or warranty of Buyer contained in or
made  pursuant  to  this  Agreement (regardless of whether such breach is deemed
"material"); (b) the breach of any covenant of Buyer contained in this Agreement
(regardless of whether such breach is deemed "material") and (c) claims relating
to  use  or  operations  of  the  Purchased  Assets  or Business after Closing .

     7.3.     Limitation  on  Indemnification  and Liability.  Except for claims
              ----------------------------------------------
based  on  intentional  fraud,  the  period of liability of Company to Buyer and
Buyer  to  Company  for  any loss or claim, by way of indemnification or for any
other  loss,  claim  or  remedy  in  connection  with any matter related to this
Agreement  shall begin on the Closing Date and terminate on the earlier to occur


                                       10

of  the  expiration  of the applicable statute of limitations or three (3) years
following  the  Closing.  For a claim based on intentional fraud, the three-year
period  shall be extended pursuant to the applicable tolling provisions, if any,
in  effect  in  Maryland  (all  the  foregoing  in the previous two sentences is
referred  to  as  the  "Survival Period").  The parties agree that any claim for
indemnification  or liability of whatever nature shall be pursued exclusively as
provided  in  Section  7.4  or 7.5.  The parties agree that the representations,
warranties  and covenants contained in this Section 7.3 between the parties is a
significant  inducement  for  them  to  approve  and  consummate this Agreement.

     7.4.     Notice  and  Arbitration  of  Claims for Indemnification Among the
              ------------------------------------------------------------------
Parties.

          7.4.1     Notice.  The Person or Persons seeking indemnification under
                    ------
this  Article7 (the "Indemnified Party") shall notify the Person or Persons from
whom  indemnification  is  sought  (the  "Indemnifying Party") in writing of its
claim  for  indemnification (including the amount thereof) within the applicable
Survival  Period.  Notices  shall  be  sent  as  provided for in this Agreement.

          7.4.2     Objection  to  Notice.  The  Indemnifying  Party  shall have
                    ---------------------
thirty  (30)  Business Days (the "Arbitration Review Period") after receipt of a
notice  under  this  section  within which to accept such claim or to reasonably
object  thereto  in  writing.  Failure of the Indemnifying Party to so object in
writing  within  the  Arbitration Review Period shall conclusively be deemed its
approval  to  the  claim for indemnification submitted by the Indemnified Party.
In  the event the Indemnifying party timely objects in writing, the Indemnifying
Party  and  the  Indemnified  Party  shall attempt to agree upon the appropriate
amount,  if  any,  of such claim for indemnification using their best good faith
efforts.  If  the  parties  fail to reach agreement within fifteen (15) Business
Days following the Arbitration Review Period (the "Outside Agreement Date") then
the  parties  shall  submit  the  dispute  to  arbitration  as  provided herein.

7.5     Indemnification  for  Matters  Involving  Third  Parties.
        --------------------------------------------------------

          7.5.1     Each  of the parties shall promptly notify the other parties
of  any  matter  asserted  by any Person other than a party to this Agreement (a
"Third  Party")  which  may  give rise to a claim for indemnification under this
Article  7  (a  "Third Party Claim"); provided that any delay by the Indemnified
Party  in  providing notice shall not affect the right of indemnification unless
the Indemnifying Party's interests have been materially prejudiced by the delay,
and  any  such  notice  shall  comply  with  Section  7.4.1.

          7.5.2     An  Indemnifying  Party  may  defend  an  Indemnified  Party
against  any  Third  Party Claim giving rise to a right of indemnification under
this  Article  7  provided  (i)  the Indemnifying Party notifies the Indemnified
Party  in  writing within fifteen (15) days after receipt of the notice required
in  Section  7.5.1  that  the  Indemnifying Party will indemnify the Indemnified
Party  as  required  by this Agreement, (ii) the Indemnifying Party provides the
Indemnified Party with reasonable evidence that the Indemnifying Party will have
the  financial  resources  to  both  undertake  the  defense  and  fulfill  its
indemnification  obligations,  (iii)  the  Third Party Claim involves only money
damages  and  does  not  seek  equitable  relief,  (iv) the settlement of, or an
adverse  judgment  with  respect  to,  the Third Party Claim is not, in the good
faith  judgment  of  the  Indemnified  Party, likely to establish a precedential
custom  or  practice  materially adverse to the continuing business interests of


                                       11

the  Indemnified  Party,  and (v) the Indemnifying Party conducts the defense of
the  Third Party Claim actively and diligently.  The Indemnifying Party's choice
of  legal  counsel  for  a  defense under this Section 7.5.2 shall be reasonably
satisfactory  to  the  Indemnified  Party.

          7.5.3     At  any time an Indemnifying Party is conducting the defense
of  a  Third Party Claim in accordance with Section 7.5.2, the Indemnified Party
may  retain  separate  co-counsel  at its own expense and participate in its own
defense.  If  both  the  Indemnifying  Party  and  the  Indemnified  Party  are
participating  in the defense, neither will consent to the entry of any judgment
or  enter  into any settlement with respect to the Third Party Claim without the
other's  prior  written  consent,  which  shall  not  be  withheld unreasonably.

          7.5.4     If, however, at any time an Indemnifying Party is conducting
the  defense  of the Third Party Claim but not in accordance with Section 7.5.2,
the  Indemnified  Party may conduct its own defense and may consent to the entry
of  any  judgment  or  enter into any settlement with respect to the Third Party
Claim  in  any  manner  it  may reasonably determine without consulting with the
Indemnifying  Party  or  obtaining  its approval, in which case the Indemnifying
Party  shall  promptly  and  at  reasonable intervals periodically reimburse the
Indemnified  Party  for  the  costs  of  its  defense.

9.     TERMINATION

     9.1.     Right  of  Termination  Without  Breach.
              ---------------------------------------

               This Agreement may be terminated without further liability of any
party  at  any  time  prior  to  the  Closing:

          9.1.1.     by  mutual  written  agreement  of  Buyer  and  Company; or

          9.1.2.     by  either  Buyer  or Company if the Closing shall not have

any way terminate, limit or restrict the rights and remedies of any party hereto
against any other party which has violated, breached or failed to satisfy any of

provision  for  which  survivorship  is  expressly  provided,  shall  survive
termination.

10.   MISCELLANEOUS

Any  failure to perform, controversy or claim arising out of or relating to this

exclusively by arbitration in accordance with the provisions of this Section and
in  accordance  with  the  rules  of  the  American  Arbitration Association for
arbitrating  commercial  matters.  The  arbitration shall be held in Washington,
D.C.,  the  surrounding metropolitan area of Maryland, or such other location as
the  parties  shall  mutually  agree.  The arbitrators shall base their award on
applicable  Maryland law and judicial precedent, and shall accompany their award
with  written  findings  of  fact  and  conclusions  of law. The decision of the
arbitrators  shall  be  binding on the parties, except that any party may appeal
the  arbitrators' decision by filing an action to reconsider the decision of the
arbitrators  in  a  court  having jurisdiction hereunder. In any such action the
arbitrators'  findings  of  fact shall be conclusive and binding on both parties
and the sole questions to be determined by the court shall be (i) whether or not
the  arbitrators'  decision was contrary to Maryland law and judicial precedent,
and  (ii) if the court determines that the arbitrators' decision was contrary to
Maryland  law  and  judicial  precedent,  then how the dispute shall be resolved
based  on  the  arbitrators'  findings  of  facts  and Maryland law and judicial
precedent.  The  decision of the court as to the resolution of the dispute under
Maryland  law  and judicial precedent shall supercede the arbitrators' decision.
Judgment  upon  the award rendered by the arbitrators, as modified by the court,
if  applicable,  may  be  entered in any court having jurisdiction in accordance
herewith.

another  arbitrator  to  serve with them so that there shall be an odd number of
arbitrators.  Alternatively, the parties may agree to accept a single arbitrator
to  be mutually agreed upon by the parties. Each person serving as an arbitrator
hereunder  shall  be  a  professional  with  excellent academic and professional
credentials  who  has  had  experience  as  an arbitrator and at least ten years
experience  in  the  field  of  resolving  commercial disputes in the Washington
Metropolitan  area.

     11.2     Discovery.   Each  party  shall,  upon  the written request of the
              ---------
other  party,  provide the other with copies of documents relevant to the issues
raised thereby.  Other discovery may be ordered by the arbitrators to the extent
the arbitrators deem additional discovery appropriate, and any dispute regarding
discovery,  including disputes as to the need therefor or the relevance or scope
thereof,  shall  be  determined by the arbitrators, which determination shall be
conclusive.

     11.3     Expenses.  Each  party  shall pay its own expenses incurred in any
              --------
arbitration  proceeding, except as may be otherwise provided by the rules of the
