                                    AGREEMENT
                                    ---------

         NOW,  THEREFORE,  in  consideration  of the foregoing  recitals and the
mutual covenants set forth in this Agreement, the parties agree as follows:

                  1.  Employment.  Employer hereby employs Employee and Employee
hereby accepts such  employment,  to perform such duties and services for and on
behalf of  Employer as may,  from time to time,  be  determined  by the Board of
Directors or  President of Employer,  as  applicable,  and are  consistent  with
Sections 1(a),  1(b) and 1(c) hereof.  Subject to Sections  1(a),  1(b) and 1(c)
hereof,  Employee  shall devote  Employee's  full and undivided  business  time,
attention  and  efforts  to  Employer's  business  and  to  the  performance  of
Employee's duties under this Agreement,  and shall fully and faithfully  perform
all duties assigned to Employee under this Agreement, consistent with Employee's
position hereunder, to the best of Employee's abilities.

                           (a)  Initially.  Following the execution and delivery
of this Agreement,  for a period of time not to exceed six (6) months,  Employee
shall (i) serve as  President  of  Employer  and shall  perform  such duties and
responsibilities  as are consistent with that of President,  and consistent with
the duties and responsibilities performed by Employee while President of Silicon
Valley Test & Repair, Inc., a California corporation;  (ii) assist Employer with
finding,  hiring and  educating a new  President of  Employer;  and (iii) work a
minimum of forty (40) hours per week, at least  twenty-four  (24) hours of which

                           (b)  Thereafter.  Once a new President has been hired
and educated,  Employee shall (i) have the title of, and perform such duties and
responsibilities  as are  consistent  with that of, Vice  President of Strategic
Technology  Development;  and (ii) work full time, only (24) hours of which must
be at Employer's  principal  place of business,  and the remaining time Employee
shall be on call.

                           (c) Santa Clara County. Employer agrees that Employee
will be  based  in Santa  Clara  County,  California,  and  that a  majority  of
Employee's  work  may be  done  in  Santa  Clara  County,  California.  Employee
understands and agrees, however, that Employee's duties and responsibilities may
require Employee to travel from time to time, and Employee agrees to do so.

                  2.  Compensation.  Employee shall be entitled to receive a per
annum  salary of Two Hundred  Thousand  Dollars  ($200,000)  ("Salary")  as full
compensation  for all the  services  rendered  by  Employee  during  the term of
Employee's  employment  hereunder.  Employee  shall be  entitled  to receive the
Salary in 26 equal  payments;  payments  to be made  every  two weeks  (less all
applicable  deductions  for all  taxes,  including  federal,  state,  and  FICA;
insurance; pension plans; etc.).

                  3. Other Benefits.  In addition to Employee's  Salary,  during
the term of Employee's employment  hereunder,  Employee shall be entitled to the
benefits  set  forth  below  in this  Section  3.  As  used  in this  Agreement,
"Comparable Level Employees" means the principal officers of Employer.

                           (a) Pension  Plans.  Participation  in such  pension,
profit sharing and deferred  compensation plans and programs,  if any, as may be
provided from time to time to other Comparable Level Employees.

                           (b) Medical  and Dental  Benefits.  Participation  in
such group medical,  accident and dental plans,  if any, as may be provided from
time to time to other Comparable Level Employees.

                           (c)  Life   and   Disability   Insurance.   Life  and
disability  insurance,  if any,  as may be  provided  from time to time to other
Comparable Level Employees.  Employer will pay the disability  insurance premium
for Employee.

                           (d)  Vacation.  Receive three (3) weeks paid vacation
during each calendar  year.  Vacation shall be taken at such times as determined
by Employee and approved by Employer. Up to two (2) weeks' vacation time that is
not used in a  particular  year may be carried  forward  into the next  calendar
year,  and only five (5) weeks'  vacation may be taken in any one calendar year.
Employee must take any vacation  time that is not allowed to be carried  forward
or the unused vacation time will be lost,  unless Employer  otherwise  agrees or
Employer did not approve the vacation time requested by Employee.

                           (e)  Reimbursement.  Reimbursement  within 30 days of
the  submittal of an approved  expense  report,  for all ordinary and  necessary
out-of-pocket  business  expenses  incurred by Employee in  connection  with the
business  of Employer  and  Employee's  duties  under this  Agreement.  The term
"business  expenses"  shall  include  any item of  expense  that is  reasonable,
ordinary or  necessary in relation to  Employee's  duties  hereunder.  To obtain
reimbursement,  Employee shall submit to Employer receipts, bills or sales slips
for the expenses incurred.

                           (f) Other  Benefits.  Such other  fringe  benefits as
Employer may make generally available on a nondiscriminatory  basis to all other
employees of Employer.

                  4. Term of Employment.

                           (a)   Employment   Term.   The  term  of   Employee's
employment  hereunder shall commence on the date hereof,  and shall terminate on
December 31, 1999,  unless  earlier  terminated in accordance  with the terms of
this Agreement.
                                        2

                           (b) Termination.  Notwithstanding  anything contained
in this Agreement to the contrary,  Employee's  employment hereunder is entirely
at will, and may be terminated by Employer with or without  cause,  subject only
to the payment obligations of Employer as hereafter set forth.

                                    (i)  In  the   event   Employer   terminates
Employee's  employment  hereunder for Cause (as hereafter  defined),  Employee's
employment  hereunder shall immediately  terminate on the effective date of such
termination as  established by Employer,  and Employee shall only receive Salary
and any other benefits under this Agreement  prorated through the effective date
of Employee's termination.

                                    (ii)  In  the  event   Employer   terminates
Employee's  employment  hereunder  without Cause, then for the remaining term of
this Agreement,  as severance pay and as total  compensation and restitution for
such  termination,  Employee  shall  receive  for  the  remaining  term  of this
Agreement:  (A)  Employee's  Salary which shall be paid at the times it would be
paid if Employee was still employed by Employer under this Agreement, subject to
the same deductions and withholdings,  and (B) either, at Employer's discretion,
(1) the same  medical  benefits  as  Employee  would be  entitled  to receive if
Employee was still  employed by Employer  under this  Agreement or (2) the COBRA
amount  necessary  for  Employee to maintain  such medical  benefits;  provided,
however,  that if Employee accepts  employment  during the remaining term of the
Agreement and as part of that  employment  Employee  receives  medical  benefits
similar to those Employee received  immediately prior to such termination,  then
Employer's  obligations under this Section  4(b)(ii)(B) shall terminate early on
the date Employee begins receiving such medical benefits from his new employer.

                           (c) Cause.  For purposes of this  Agreement,  "Cause"
means:  (i)  "Total  and  Permanent  Incapacity"  (as  hereinafter  defined)  of
Employee;  (ii) the failure or inability  (not as a consequence  of any illness,
accident or other  disability,  as confirmed by competent  medical  evidence) of
Employee  to  perform   Employee's  duties  hereunder  in  a  manner  reasonably
satisfactory  to  Employer's  Board of  Directors,  provided the decision of the
Board of Directors is not arbitrary or capricious,  and is not made in bad faith
and  further  that the  failure  or  inability  is not as a  consequence  of any
illness,  accident  or  other  disability  as  confirmed  by  competent  medical
evidence;  (iii) "Serious Misconduct" (as hereinafter  defined) of Employee;  or
(iv) the breach of any of the terms or conditions contained in this Agreement.

                           For purposes of this Agreement,  "Total and Permanent
Incapacity"  means such  physical or mental  condition  of  Employee,  including
alcoholism,  which renders Employee  incapable of performing  Employee's  duties
hereunder for more than 90 days. In the event Employee is a Qualified Individual
with a Disability,  as defined in the American with  Disabilities  Act, Employer
shall not  terminate  Employee's  employment  hereunder  if  Employee is able to
perform the  essential  functions of Employee's  job with or without  reasonable
accommodation from Employer.

                           For purposes of this Agreement,  "Serious Misconduct"
means embezzlement or misappropriation of corporate funds; the furnishing of any
information,  reports,  documents or  certificates by Employee to Employer which
Employee knew or believed to be false or  misleading;  dishonesty of any kind in
relations with Employer or its customers; activities harmful to the
                                        3

reputation of Employer (other than as a consequence of good faith decisions made
by Employee in the normal  performance  of  Employee's  duties  hereunder);  the
conviction  of or the plea by Employee  to any  criminal  felony  offense or any
criminal  offense  regarding  dishonesty or moral  turpitude;  or the refusal to
perform the duties assigned to Employee  pursuant to this Agreement (unless such
duties shall be unlawful).

                           Employer  agrees to act in a commercially  reasonable
fashion in terminating for Cause,  and shall give Employee notice of any failure
by Employee to conform his conduct to the  requirements of this Agreement and an
appropriate amount of time to cure such failure,  the exact amount of time to be
determined by Employer in a commercially reasonable fashion, based upon the type
of failure  involved.  Employer  and  Employee  acknowledge  and agree that some
failures  (which  failures  Employer and Employee are not defining other than as
those failures  Employer  determines,  in a "commercially  reasonable  fashion,"
qualify) will not require any notice to be given, and Employee may be terminated
immediately for "Cause" in those situations.

                           Notwithstanding  anything contained in this Agreement
to the  contrary,  Employee  may  resign  and  terminate  Employee's  employment
hereunder, with or without cause, subject to the requirement that Employee shall
provide  Employer  with not less than 45 days'  prior  written  notice.  In such
event,  Employee  shall not receive any Salary or any other  benefits under this
Agreement after the effective date of Employee's resignation.

                           (d)  Death.  In the  event of the  death of  Employee
during the term of this  Agreement,  this  Agreement and  Employee's  employment
hereunder  shall  terminate  as of  the  date  of the  death  of  Employee,  and
Employee's estate or personal representative shall be entitled to receive Salary
and other fringe  benefits  prorated for the period of Employee's  employment to
the date of death, payable within 60 days after the date of death.

                           (e)  Suspension.  Employer  shall  have the  right to
suspend  Employee with full pay and benefits for any period of time the Board of
Directors of Employer deems, in its sole discretion, necessary or appropriate to
investigate Employee's conduct in connection with Section 4(c) hereof.

                  5. Noncompetition.  During the period of Employee's employment
hereunder,  and for a period of eighteen  (18) months from and after the date of
expiration or earlier  termination of Employee's  employment  hereunder (or such
lesser  period to the maximum  extent  permitted  by  applicable  law),  neither
Employee  nor any  person or  entity  controlled  (directly  or  indirectly)  by
Employee, whether as employer, employee, proprietor, partner, stockholder (other
than the holder of less than 5% of the stock of a corporation  the securities of
which are traded on a national  securities  exchange or in the  over-the-counter
market),  director,  officer,  consultant,  agent or otherwise, shall within the
Restricted  Territory (as defined below) engage or cause others to engage in the
Business unless first authorized in writing by Employer, which authorization may
be withheld in the sole and absolute  discretion  of  Employer.  For purposes of
this Agreement,  the term "Restricted Territory" shall mean the United States of
America,  and all other countries in which Employer conducts the Business on the
date  hereof.  If Employee  violates  Employee's  obligations  contained in this
Section 5, then the time  periods  hereunder  shall be extended by the period of
time  equal to that  period  beginning  when the  activities  constituting  such
violation  commenced and ending when the activities  constituting such violation
terminated.
                                        4

                  6. Nonsolicitation. During the period of Employee's employment
hereunder,  and for a period of eighteen  (18) months from and after the date of
expiration or earlier  termination of Employee's  employment  hereunder (or such
lesser  period to the maximum  extent  permitted  by  applicable  law),  neither
Employee  nor any  person or  entity  controlled  (directly  or  indirectly)  by
Employee whether as employer, employee, proprietor,  partner, stockholder (other
than the holder of less than 5% of the stock of a corporation  the securities of
which are traded on a national  securities  exchange or in the  over-the-counter
market), director, officer, consultant, agent or otherwise, shall solicit (a) in
respect of the  Business,  any person or other entity that is, or was within the
previous 12 month period  immediately prior to the date of expiration or earlier
termination  of  Employee's  employment  hereunder,  a customer  or  supplier of
Employer,  or (b) any person who, on such date, is an employee of Employer,  for
employment,  or as an independent  contractor with any person or entity,  unless
first authorized in writing by Employer,  which authorization may be withheld in
Employer's  sole  and  absolute  discretion.  If  Employee  violates  Employee's
obligations  contained in this Section 6, then the time periods  hereunder shall
be  extended  by a  period  of time  equal  to that  period  beginning  when the
activities  constituting such violation commenced and ending when the activities
constituting such violation terminated.

                  7. Trade Secrets and Other Confidential Information.  From and
after the date hereof,  Employee shall not communicate or divulge to, or use for
the benefit of, any  person,  firm or  corporation  other than  Employer  and/or
Employer's subsidiaries, and its or their agents and representatives, any of the
trade secrets, methods, formulas,  business and/or marketing plans, processes or
any other  proprietary  or  confidential  information  with  respect to Employer
and/or  Employer's  subsidiaries,  its or their business,  financial  condition,
business operations or methods,  or business  prospects.  The preceding sentence
shall not apply to information  which (a) is, was or becomes  generally known or
available to the public or the  industry  other than as a result of a disclosure
by Employee in violation of this  Agreement,  or (b) is required to be disclosed
by law. Employee shall advise Employer, in writing, of any request,  including a
subpoena  or  similar  legal   inquiry,   to  disclose  any  such   confidential
information,   such  that  Employer  and/or  Employer's  subsidiaries  can  seek
appropriate legal relief.

                  8.  Return  of  Employer   Property.   Immediately   upon  the
expiration or earlier termination of this Agreement and if Employee is no longer
employed by Employer,  Employee shall return to Employer any and all property of
Employer, including, but not limited to, all documents,  agreements,  schedules,
statements, customer lists, supplier lists, plans, designs, parts and equipment,
that is in the possession or control (direct or indirect) of Employee.

                  9.   Survival/Remedies/Severability.   Employee   specifically
acknowledges that (a) Employer currently has operating facilities located in the
Restricted  Territory;  (b)  Employer  receives  much of its  business  from and
throughout  the  Restricted  Territory;  (c)  Employer  has plans to expand  its
operations  throughout  the  Restricted   Territory;   and  (d)  the  geographic
restrictions  contained in Section 5 hereof, and the length of time restrictions
in  Sections  5, 6 and 7  hereof  are each  necessary  and  reasonable  and were
negotiated with Employer. The restrictions and obligations set forth in Sections
5, 6, 7 and 8 hereof shall survive the expiration or earlier termination of this
Agreement.  The parties hereby  acknowledge and agree that the  restrictions and
obligations  set  forth in  Sections  5, 6, 7 and 8 hereof  are  reasonable  and
necessary,  and that any  violation  thereof  would  result in  substantial  and
irreparable  injury to  Employer,  and that  Employer  may not have an  adequate
remedy at law with respect to any such violation.  Accordingly,  Employee agrees
that, in
                                        5

the event of any actual or threatened violation thereof, Employer shall have the
right and  privilege to obtain,  in addition to any other  remedies  that may be
available,  equitable  relief,  including  temporary  and  permanent  injunctive
relief, to cease or prevent any actual or threatened  violation of any provision
hereof.  Each and every  provision set forth in Sections 5, 6, 7 and 8 hereof is
independent and severable from the others,  and no restriction  will be rendered
unenforceable by virtue of the fact that, for any reason, any other or others of
them may be  unenforceable  in whole or in part. If any provision in Sections 5,
6, 7 or 8 hereof is unenforceable for any reason whatsoever, that provision will
be  appropriately  limited  and  reformed  to the  maximum  extent  provided  by
applicable law. If the scope of any restriction contained herein is too broad to
permit  enforcement to its full extent,  then such restriction shall be enforced
to  the  maximum  extent  permitted  by law so as to be  judged  reasonable  and
enforceable,  and the  parties  agree  that  such  scope may be  modified  by an
arbitrator or judge in any proceeding to enforce this Agreement.  This includes,
without  limitation,  altering  or  enforcing  only  portions  of the  limits on
activity   restrictions,   the  geographic   scope,  and  the  duration  of  the
restrictions unless to do so would be contrary to law or public policy.

                  10. Inventions.

                           (a)  Assignment.  Employee  agrees  that  any and all
inventions,   including   any   improvements,    innovations   and   discoveries
(collectively  "Inventions")  that  Employee  conceives,  develops or reduces to
practice, and all copyrightable materials and trademarks  (collectively "Works")
that Employee prepares alone or with others during Employee's term of employment
under  this  Agreement:   (i)  that  relate  to  Employer's   and/or  Employer's
subsidiaries actual or foreseeable business;  (ii) that Employee works on during
Employee's working hours for Employer and/or Employer's  subsidiaries;  or (iii)
for which Employee uses Employer facilities or materials, will be and remain the
sole and exclusive  property of Employer.  Employee hereby  irrevocably  assigns
Employee's  entire  right,  title  and  interest  in and to each  of  Employee's
Inventions and Works to Employer  and/or  Employer's  subsidiaries,  free of any
compensation beyond Employee's compensation as an employee of Employer. Employee
agrees to assist in the  preparation of  applications  for patent or other legal
protection  of  Inventions  and Works in all  countries  of the world,  and will
reasonably  cooperate with Employer in defending the validity or  enforceability
of such protection.  Employee  further agrees to execute all documents  Employer
may from time to time request to perfect the  assignment  of the  Inventions  or
Works throughout the world.

                           (b)  Assignment   after  Expiration  or  Termination.
Employee  agrees  that  any  Inventions  or  Works  that  Employee  asserts  are
conceived,  developed or reduced to practice by Employee,  alone or with others,
within six months immediately following the expiration or earlier termination of
Employee's  employment  hereunder  that  relate  to the  actual  or  foreseeable
business of Employer and/or  Employer's  subsidiaries,  will be presumed to have
been made during the term of Employee's employment and will be the sole property
of  Employer,  unless  Employee  presents  sufficient  evidence  to  Employer to
satisfactorily rebut the presumption.

                  11. Miscellaneous.

                           (a) Notices.  All notices required or permitted to be
given  hereunder shall be in writing and shall be deemed given when delivered in

                           (c)  Non-Waiver.  The  failure  in any  one  or  more
instances of a party to insist upon  performance of any of the terms,  covenants
or  conditions  of this  Agreement,  to exercise  any right or privilege in this
Agreement  conferred,  or the  waiver by said  party of any breach of any of the
terms,  covenants or conditions of this  Agreement,  shall not be construed as a
subsequent  waiver  of  any  such  terms,  covenants,   conditions,   rights  or
privileges,  but the same shall  continue and remain in full force and effect as
if no such  forbearance  or waiver had  occurred.  No waiver  shall be effective
unless it is in  writing  and  signed  by an  authorized  representative  of the
waiving party. A breach of any representation, warranty or covenant shall not be
affected  by the  fact  that a more  general  or more  specific  representation,
warranty or covenant was not also breached.

                           (d)  Attorneys'  Fees.  If any  action is  brought to
enforce this Agreement or to collect  damages as a result of a breach of any its
provisions,  the  prevailing  party  shall  also  be  entitled  to  collect  its
reasonable  attorneys'  fees and costs incurred in such action,  which costs can
include the reasonable costs of investigation, expert witnesses and the costs in
enforcing or collecting any judgment rendered,  all as determined and awarded by
the Court.

                           (e)  Counterparts.  This Agreement may be executed in
multiple  count- erparts,  each of which shall be deemed to be an original,  and
all such counterparts shall constitute but one instrument.

                           (f) APPLICABLE  LAW. THIS AGREEMENT SHALL BE GOVERNED
AND CONTROLLED AS TO VALIDITY, ENFORCEMENT, INTERPRETATION, CONSTRUCTION, EFFECT
AND IN ALL  OTHER  RESPECTS  BY THE  INTERNAL  LAWS OF THE  STATE OF  CALIFORNIA
APPLICABLE TO CONTRACTS MADE IN THAT STATE.

                           (g) Construction.  The parties hereto acknowledge and
agree that each party has  participated  in the drafting of this  Agreement  and
that this  document has been  reviewed by the  respective  legal counsel for the
parties hereto and that the normal rule of  construction  to the effect that any
ambiguities  are to be resolved  against the drafting party shall not be applied
to the  interpretation of this Agreement.  No inference in favor of, or against,
any party  shall be drawn from the fact that one party has  drafted  any portion
hereof.
