hereto mutually agree as follows:

                                    AGREEMENT

     1.  Employment.  Employee shall be employed by Employer as Vice  President,
Sales  and  Marketing,   reporting   directly  to  the   President.   Employee's
responsibilities  are  expected  to  generally  include  but not be  limited  to
Direction and  Management  of all Sales  Functions  and, as required,  marketing
functions of the Company.

     2.  Term.  The term of  employment  of  Employee  by  Employer  under  this
Agreement  shall begin as of the Agreement  Date and be for a period of Four (4)
calendar years thereafter,  unless terminated pursuant to Paragraphs 11, 12, 13,
14, or 15 of this Agreement.  Employee hereby accepts employment subject to this
Agreement's ratification by the Company's Board of Directors.

     3.  Best  Efforts  of  Employee.  Employee  agrees to  perform  faithfully,
industriously,  and to the best of Employee's ability,  experience, and talents,
all of the duties that may be required by the express and implicit terms of this
Agreement,  to the  reasonable  satisfaction  of Employer.  Such duties shall be
provided  at such  place(s)  as the needs,  business,  or  opportunities  of the
Employer may require from time to time.

     4. Performance.  During Employee's  employment  Employee will not engage in
any  activity  that  conflicts  with  Employer's  business  interests  so  as to
interfere  with the proper and efficient  performance  of  Employee's  duties at
Employer.

     5.  Compensation.  As  compensation  for the services  provided by Employee
under this  Agreement,  Employer  will pay Employee an annual base salary ("Base

                                                         1

<PAGE>

          Dates                         Amount
       -------------                 ---------------
       First Year                    $ 93,500.00
       Second Year                   $100,045.00
       Third Year                    $107,048.00
       Fourth Year                   $114,541.00

Employee's  starting Base Salary is Ninety Three  Thousand Five Hundred  dollars
($93,500.00). It is expected that no salary can or will be paid during the first
Four (4) Months of  employment.  No salary will be accrued during the First Four
(4) Months of employment in which no salary can be paid.  Employee  acknowledges
that the  Employer's  ability to pay any  salary is  dependent  solely  upon the
Company's ability to secure and maintain working capital  throughout the term of
this Agreement  sufficient to maintain full operational  status of the Employer.
If the Employer  does not pay the  Employee's  Base Salary during the First Four
(4) Months of  employment,  the  Employer  will  compensate  the Employee in the
amount of Five Thousand (5,000) shares of the Company's  restricted Common Stock
for each pay  period in which no salary is paid.  In the event  that a salary is
not paid in any months  following the first Four (4) months of  employment,  the
Employer will  compensate the Employee by the accrual of the Employee's  monthly
Base Salary plus Five Hundred  (500) shares of the Company's  restricted  Common
Stock  for  each pay  period  in which a salary  is not  paid.  All  stock to be
received in lieu of salary for the year 2000 will be issued not later than March
31, 2001 when  authorized  by the  Company's  Board of  Directors.  In the event
Employee  voluntarily quits prior to any Base Salary being paid,  Employer shall
not be obligated to accrue any further compensation beyond the Termination Date.

         6. Additional  Compensation.  In addition to Base Salary,  the Employer
will make quarterly  commission  payments to the Employee of a One-Half  percent
(0.5%)  override  commission  based  on  gross  sales  of the  Company  products
exclusive of taxes,  freight and fees.  In addition to the override  commission,
the Employer will make a commission  payment of One-Half  percent  (0.5%) to the
Employee for all direct sales by the Employee.  All commission  payments will be
paid on the  Fifteenth  day of the  month  with  Fifty  percent  (50%) of direct
commissions paid in the month following  shipment and Fifty percent (50%) or the
adjusted  balance  of these  commissions  paid upon  close of the  project.  The
project  will be  considered  closed when the final  billing to the  customer is
placed on the books of the  Employer.  Employee  will not receive any portion of
pooled commissions shared by other employees of Employer whose payment amount is
determined  by  Employee.  If the budget  plan is met,  the  employee  will also
receive such additional compensation as may be determined by the Company's Board
of Directors or by a compensation committee of the Board of Directors.

         7. Stock  Options.  Employee is hereby granted the right to purchase up
to  One  Hundred  Thousand  (100,000)  shares  of  the  Company's  Common  Stock

Common Stock.  Employee  must  exercise each vested option by written  notice to
Employer. The Options shall become vested according to the following formula and
subject to the  following  terms:  a)  Twenty-Five  percent (25%) of the Options

(i) directly to the business of Employer,  or (ii) to the  Employer's  actual or
demonstrably  anticipated  research or development,  or b) the invention results
from any work  performed by the Employee  for the  Employer,  in which cases the
above assignment  shall apply.  This is a continuing  assignment,  which becomes
automatically  effective  immediately  upon the creation of each such  invention
(each an "Assigned Invention").

               22.3  Identification of Prior  Inventions.  Employee has attached
hereto a list  describing all Inventions  belonging to him and made by him prior
to his  employment  with  Employer  that he  wishes to have  excluded  from this
Agreement.  If no such list is attached,  Employee  represents that there are no
such  Inventions.  If in the  course of his  employment  at  Employer,  Employee
incorporates into an Employer product, process, or machine, or otherwise uses in
an Employer  product,  an invention owned by him or in which he has an interest,
Employer  is  hereby   granted  and  shall  have  an   exclusive   royalty-free,
irrevocable,  worldwide license to make, have made, use, and sell that invention
without restriction as to the extent of Employee's ownership or interest.

               22.4 Disclose and Assist.  Employee shall  promptly  disclose all
Assigned  Inventions in writing to Employer,  shall assist Employer in preparing
patent  or  copyright   applications  for  Assigned  Inventions,   execute  said
applications  and all other  documents  required to obtain patents or copyrights
for Assigned Inventions, and execute all documents Employer deems appropriate to
vest title  thereto in Employer,  at Employer's  expense,  but for no additional
consideration  or  compensation  to  Employee.  In the event  Employer  requires
assistance  under this  paragraph  after  Employee's  termination of Employment,
Employee shall provide such assistance with mutually agreed upon compensation.

               22.5 Execute  Agreements.  During the term of employment or after
termination, on request of Employer, Employee shall execute specific assignments
in  favor  of  Employer  of any of  the  Assigned  Inventions  covered  by  this
Agreement,  as well as  execute  all  papers and  perform  all lawful  acts that
Employer  considers  necessary or advisable  for the  preparation,  prosecution,
issuance,  procurement and maintenance of patent or copyright  applications  and
patents and  copyrights  of the United  States and foreign  countries  for these
Assigned  Inventions,  and for transfer of any interest  Employee may have,  and
Employee shall execute all documents  Employer deems  necessary to vest title in
Employer  in and to the  Assigned  Invention.  Notwithstanding  the  above,  the
absence of  Employer  request  for a  specific  assignment  hereunder  shall not
negate,  affect,  defeat or limit in any way Employer's  title to, and exclusive
property  interest in the Assigned  Invention  under  Paragraph 22.2 above which
assignment is a continuing and choate  conveyance  specifically  enforceable and
effective for all purposes.

         23.  Right to  Possession  of  Information,  Documents  and  Materials.
Employee agrees that upon request by Employer, and in any event upon termination
of  employment,  Employee  shall turn over to  Employer  all  documents,  notes,
papers,  data files,  office  supplies  or other  materials  or work  product in
Employee's  possession or under  Employee's  control which were created pursuant
to, are connected with or derived from Employee's services to Employer, or which
are related in any manner to  Employer's  business  activities  or research  and
development  efforts,  or which  constitute  or relate to  Assigned  Inventions,
whether or not such  material are at the date of this  Agreement  in  Employee's
possession. Employee agrees that all such documents, notes, papers, data, files,
office supplies,  materials,  work product and Assigned  Inventions are the sole
property of Employer.

         24. Non-Competition. Employee recognizes and acknowledges that, because
of the confidential  and sensitive  nature of the  Confidential  Information and
because  the use of,  or even the  appearance  of the use of,  the  Confidential
Information by Employee in certain  circumstances  will cause irreparable damage
to Employer and its reputation,  Employer would not offer employment to Employee
unless Employer were assured that such misuse would not occur.  Employee further
recognizes and acknowledges that because the goodwill of Employer's  business is
a valuable  asset,  and because the  solicitation  of  Employer's  customers  or
clients by Employee,  after  Employee has ceased to be employed by or associated
with Employer, will cause irreparable harm to the goodwill of Employer, Employer
would not offer or continue to offer such employment to Employee unless Employer
were assured that such solicitation  would not occur.  Employee therefore agrees
and covenants that during Employee's  employment by Employer and for a period of
Two (2) years  following  the  termination  of such  employment  for any reason,
Employee will not directly or indirectly engage in any of the following:

                  24.1  Anywhere  in the  United  States or  worldwide,  design,
develop,  manufacture,  produce, sell or market any product, service, concept or
business  line on which  Employee  worked,  learned  of, or had access to during
Employee's  employment  which is  competitive  with any aspect the  business  of
Employer as presently  conducted or as said business may evolve between the date
of this Agreement and the date of Employee's termination of employment.

                  24.2 Have any direct or indirect business dealings or contacts
with any  customer  or client of  Employer  or any person or firm which has been
contracted  or  identified  by  Employer  as a  potential  customer or client of
Employer as of the date of Employee's  termination of  employment,  except those
dealings or contacts  which  demonstrably  do not  conflict or compete  with the
business interests, products or service of Employer.

                  24.3  Employee agrees that this non-compete provision will not
adversely affect the Employee's livelihood.

         25. Saving  Provision.  Employer and Employee  agree and stipulate that
the agreements contained in the preceding Paragraph,  including the scope of the
restricted  activities  described  therein and the duration  and the  geographic
extent  of  such  restrictions,  are  fair  and  reasonably  necessary  for  the
protection  of  Employer's   Confidential   Information,   goodwill,  and  other
protectable  interests,  in light of all of the facts and  circumstances  of the
relationship  between  Employee and Employer.  In the event a court of competent
jurisdiction  should  decline to enforce any  provision  of  Paragraph  24, such
Paragraph shall be deemed to be modified to restrict Employee's competition

                                        8

<PAGE>

with Employer to maximum  extent,  in both time and  geography,  which the court
shall find enforceable.

         26. Effect of  Termination.  Upon  termination of this  Agreement,  for
whatever reason, whether by the Employer or Employee, all rights and obligations
pursuant to: a) Paragraphs 5, 6, and 7 of this Agreement to the extent  Employee
has not  received  Compensation  incurred  prior  to the  Termination  Date;  b)
Paragraphs  19,  20,  21,  22  and 25 of  this  Agreement  regarding  Employee's
obligations  of  Nondisclosure,  Intellectual  Property  and Remedy;  and c) any
remedial provisions of this Agreement or miscellaneous provisions related to the
interpretation  or  enforcement  of the  above  paragraphs,  shall  survive  the
termination  of  this  Agreement.  All  other  rights  and  obligations  of this
Agreement shall cease as of the Termination Date.

         27. Survival of Certain Provisions.  Notwithstanding any termination of
this  Agreement  by  reason  of the  discharge  of  Employee  or  his  voluntary
termination of  employment,  the following  provisions of this  Agreement  shall
survive and continue:  Paragraphs 19, 20, 21, 22, and 25. This Agreement and all
rights  hereunder shall inure to the benefit of the Company,  its successors and
assigns.

         28. Injunctive Relief. The Employee acknowledges that disclosure of any
Confidential   Information  or  breach  or  threatened  breach  of  any  of  the
non-competition  and  non-disclosure  covenants  or other  agreements  contained
herein would give rise to irreparable injury to Employer or clients of Employer,
which  injury  would  be  inadequately   compensable  in  money  damages  alone.
Accordingly,  Employer or, where appropriate,  a client of Employer, may seek to
obtain  injunctive relief from the breach or threatened breach of any provision,
requirement or covenant of this Agreement,  in addition to and not in limitation
of any  other  legal  remedies  which may be  available.  The  Employee  further
acknowledges,  agrees and  stipulates  that, in the event of the  termination of
employment with the Employer,  the Employee's  experience and  capabilities  are
such that the Employee can obtain employment in business activities which are of
a different and non-competing nature with his other activities as an employee of
Employer;  and that the  enforcement of a remedy  hereunder by way of injunction
shall not  prevent  the  Employee  from  earning a  reasonable  livelihood.  The
Employee further acknowledges and agrees that the covenants contained herein are
necessary for the protection of the Company's  legitimate business interests and
are reasonable in scope and content.

          29. Enforcement. The provisions of this Agreement shall be enforceable
notwithstanding  the existence of any claim or cause of action against  Employer
by Employee,  whether predicated on this Agreement or otherwise.  The provisions
of this  Agreement  shall survive the  termination  for any reason of Employee's
employment by Employer.

          30.  Disclosure  of Existence of  Agreement.  In order to preserve the
Company's rights under this Agreement,  Employer may advise any third party with
whom  Employee  may  consider,  establish  or  contract  a  relationship  of the
existence of this Agreement and of its terms pursuant only to Paragraphs 19, 20,
21, 22 and 25 of this  Agreement  and Employer  shall have no  liability  for so
doing.

          31. Governing Law. The Agreement shall be construed in accordance with
the  internal  laws of the State of  Washington,  without  giving  effect to the
principles and provisions thereof

                                        9

relating  to  conflict  or choice of laws.  Employee's  obligations  under  this
Agreement supplement and do not supersede the obligations imposed on Employee by
the laws of the State of Washington and the United States of America,  including
without limitation  obligations  imposed upon Employee by the Washington Uniform
Trade  Secrets  Act and  common  law.  The venue of any action  relating  to, or
arising from the breach or  enforcement  of any term of this  Agreement,  or the
determination  of the rights of  Employer or  Employee  hereunder,  shall be the
Superior Court of Washington for King County.

         32. Legal  Expense.  In any suit,  proceeding  or action to enforce any
term,  condition or covenant of this Agreement or to procure an  adjudication or
determination of the rights of Employer or Employee,  the prevailing party shall
be entitled to recover  from the other party a  reasonable  attorney fee and all
costs and expenses incurred in connection with such suit,  proceeding or action,
including appeal, which sums shall be included in any judgment or decree entered
therein.

          33.  Waiver of Breach.  The waiver of any breach of any  provision  of
this  Agreement or failure to enforce any provision  hereof shall not operate or
be construed as a waiver of any subsequent breach by any party.

          34.  Severability.  If one or more of the provisions of this Agreement
or any application  thereof shall be invalid,  illegal or  unenforceable  in any
respect,  the validity,  legality and enforceability of the remaining provisions
or any other application thereof shall in no way be affected or impaired.

         35.  Entire  Agreement.  Employee  acknowledges  that he has read  this
Agreement,  understands  it, has had the opportunity to consult with an attorney
of  Employee's  choosing,  and agrees to be bound by its terms.  This  Agreement
constitutes  the entire  agreement of the Parties hereto  respecting the subject
matter contained herein and supersedes all prior or  contemporaneous  written or
oral  agreements.  This  Agreement  may not be modified  or amended  except by a
writing signed by all parties hereto.

         36.  Binding Effect. This Agreement and each of its provisions shall be
binding on and endure to the benefit of the Parties  and their  heirs,  personal
representatives, successors and assigns.

         IN WITNESS  WHEREOF,  the undersigned have hereunto set their hands and
seals as of the date first above written.
