or the  Company  does  not  wish to  extend  the  term of  employment  for  such
additional one-year period.

3.     Compensation.

         3.1  Salary.  As full  compensation  for all  services  to be  rendered

subsidiary),  during the term, a salary at the fixed rate of One Hundred  Eighty
Thousand  Dollars  ($180,000)  per  annum  or such  greater  amount  as shall be

services  under this  Agreement,  upon  presentation  of expense  statements  or

qualifies.  Employee understands such benefit plans may be modified from time to
time under guidelines established by the Board of Directors.

         3.6 Company Automobile.  During the term, Employee may be entitled to a
car allowance or use of a Company automobile  consistent with the guidelines for
employees as set forth in the Company's Policies and Procedures. Employee agrees

         3.8  Limitations  Imposed  by Law.  The  provisions  of this  Agreement
relating to the  compensation to be paid to the Employee shall be subject to any
limitations  provided by law or regulation  that may from time to time limit the
compensation payable to the Employee.

4.     Termination.

         4.1 Termination  Upon Death. If the Employee shall die during the term,
this Agreement shall terminate except that the Employee's beneficiaries shall be
entitled  to receive the  Employee's  Base Salary for a period of six (6) months
following the last day of the month in which his death occurs.

         4.2  Termination  Upon  Disability.  If, during the term,  the Employee
shall become physically or mentally disabled,  whether totally or partially,  so
that he is unable  substantially  to perform his  services  hereunder  for (i) a
period of six (6) consecutive  months,  or (ii) for shorter periods  aggregating
six months  during any twelve (12) month  period,  the Company  may, at any time
after the last day of the six (6) consecutive  months of disability,  or the day
on which the shorter  periods of  disability  shall have equaled an aggregate of
six (6) months,  by written notice to the Employee,  but before the Employee has
recovered from such disability,  terminate the term of the Employee's employment
hereunder.  Notwithstanding  such disability,  the Company shall continue to pay
the Employee  sixty  percent  (60%) of his Base Salary  through the date of such
termination,  and following the end of the fiscal year in which such termination
occurs,  the amount of incentive or other bonuses,  if any, that would otherwise
have been payable to Employee  under Section 3.2 and which have accrued  through
the end of the fiscal year in which such  termination  occurs as if the Employee
had been employed by the Company for the entire fiscal year.

         4.3 Termination Without Cause. If at any time during the term, Employee
shall be  terminated  by the Company for reasons other than cause (as defined in
Paragraph  4.4),  Employee or  Employee's  estate will be entitled to receive as
severance the continuation of Base Salary, at its then current rate, through and
until  the  later of (i) one  third of the  remaining  period  to the end of the
Initial  Term,  or (ii) a period of six (6) months  from the  effective  date of
termination,  but shall not be  entitled to any  incentive  bonus for the fiscal
year during which the effective  date of termination  occurs,  or any subsequent
year.  In  addition  to  continuation  of Base  Salary,  one third of  remaining
un-vested  stock options granted in conjunction  with this employment  agreement
shall vest on the effective date of termination.

                  If  Employee's  employment  shall  be  terminated  during  any
Extended  Term,  for any reason other than cause,  Employee shall be entitled to
receive as severance the  continuation  of Base Salary for a period of three (3)
months from the effective date of termination,  but shall not be entitled to any
incentive  bonus  for  the  fiscal  year  during  which  the  effective  date of
termination occurs, or any subsequent year.

                  Notwithstanding  the  foregoing,   any  payments  to  Employee
hereunder,  whether  during the  Initial  Term or any  Extended  Term,  shall be
reduced by any  compensation  (in any form) received for services from any other
source for or during the period which  Employee  receives  any  post-termination
compensation hereunder.  These severance payments shall be in full settlement of
any claim Employee may have to compensation in any form.

         4.4 Termination by the Company for Cause.  The Company may, at any time
during the term,  terminate for cause (as  hereinafter  defined) the  Employee's
employment  hereunder,  in which event the Employee shall be entitled to receive
his Base Salary  accrued  through the effective  date of such  termination.  The
Employee  shall  have no right to  receive  any other  compensation  or  benefit
hereunder after the effective date of such termination;  provided, however, that
the foregoing shall not affect the Employee's  right to receive any compensation
or benefit under the profit  sharing/401(k)  plans. As used herein, the term for
"cause"  shall be deemed to mean and include  with  respect to the  Employee (i)
conduct of the  Employee at any time,  which has involved  criminal  dishonesty,
conviction  of the  Employee  of any felony,  or of any lesser  crime or offense
involving the property of the Company or any of its  subsidiaries or affiliates,
significant conflict of interest,  serious  impropriety,  or breach of corporate
duty, misappropriation of any money or other assets or properties of the Company
or its  subsidiaries,  (ii) willful  violation of specific and lawful directions
from  the  Board of  Directors  of the  Company  (which  directions  must not be
inconsistent  with the  provisions  of this  Agreement),  failure  or refusal to
perform the services  customarily  performed  by an executive  officer (and such
failure  or  refusal  continues  after a  written  direction  from the  Board of
Directors),  or expressly  required by the terms of this  Agreement,  or willful
misconduct  or  gross   negligence  by  the  Employee  in  connection  with  the
performance of his duties hereunder, (iii) chronic alcoholism or drug addiction,
and (iv) any other acts or conduct  inconsistent with the Company's Policies and

                                     Page 4

Procedures or the standards of loyalty, integrity or care reasonably required by
the Company of its executives.

5.     Protection of Confidential Information:  Non-Competition.

         5.1 Confidential  Information.  In view of the fact that the Employee's
work for the Company will bring him into close  contact  with many  confidential
affairs of the Company not readily available to the public, and plans for future
developments, the Employee agrees:

                  5.1.1 To keep  and  retain  in the  strictest  confidence  all
confidential matters of the Company,  including,  without limitation,  all trade
"know how",  secrets,  customer lists,  pricing policies,  operational  methods,
technical  processes,  formulae,  inventions  and research  projects,  and other
business affairs of the Company, learned by him heretofore or hereafter, and not
to disclose  them to anyone  outside of the Company,  either during or after his
employment  with the  Company,  except in the  course of  performing  his duties
hereunder or with the Company's express written consent;

                  5.1.2 To execute and fully comply with a  confidentiality  and
rights  agreement or such other similar  agreement  which may be required by the
Company from time to time, consistent with its Policies and Procedures; and

                  5.1.3 To deliver promptly to the Company on termination of his
employment  by the  Company,  or at any time the  Company  may so  request,  all
memoranda,  notes, records,  reports,  manuals,  drawings,  blueprints and other
documents  (and all copies  thereof) to the Company's  business and all property
associated therewith, which he may then possess or have under his control.

         5.2 Non-Competition.  During the term and for a period of not less than
six (6) months  following the  termination of such period,  or for any period in
which  Employee  would have been  eligible to receive Base Salary,  the Employee
shall not in any state of the United  States,  or any other  foreign  country in
which the Company shall then be doing  business,  directly or indirectly,  enter
the employ of, or render  any  services  to,  any  person,  firm or  corporation
engaged in any business  competitive  with the business of the Company or of any
of its  subsidiaries or affiliates;  he shall not engage in such business on his
own account;  and he shall not become interested in any such business,  directly
or  indirectly;  as an  individual,  partner,  shareholder,  director,  officer,
principal,   agent,  lender,  employee,   trustee,   consultant,  or  any  other
relationship  or capacity;  provided,  however,  that nothing  contained in this
Paragraph 5.2 shall be deemed to prohibit the Employee from acquiring, solely as
an  investment,  not more than 1% of the shares of  capital  stock of any public
corporation.

         In  addition,  Employee  agrees  that he shall not during  such  period
solicit,  induce or attempt to solicit or induce any  employee of the Company to
terminate  such

                                     Page 5

Employment Agreement                                                Thomas Koshy

employee's  employment with the Company in order to become employed by any other
person or entity,  without the consent of a majority of the  Company's  Board of
Directors.

         5.3  Remedies of the Company  Upon  Employee  Breach.  If the  Employee
commits a breach,  or threatens to commit a breach,  of any of the provisions of
Paragraphs  5.1 or 5.2 hereof,  the Company shall have the following  rights and
remedies:

                  5.3.1  The right and  remedy  to have the  provisions  of this
Agreement  specifically  enforced by any court having  equity  jurisdiction,  it
being  acknowledged  and agreed that any such breach or  threatened  breach will
cause  irreparable  injury to the Company and that money damages may not provide
an adequate remedy to the Company; and

                  5.3.2 The right and remedy to require the  Employee to account
for and pay over to the Company all  compensation,  profits,  monies,  accruals,
increments or other benefits  (collectively,  "Benefits") derived or received by
the Employee as the result of any  transactions  constituting a breach of any of
the provisions of the  Paragraphs 5.1 or 5.2, and the Employee  hereby agrees to
account for and pay over such Benefits to the Company.

          Each of the rights and remedies of the company shall be independent of
the  other,  and shall be  severally  enforceable,  and all of such  rights  and
remedies  shall be in  addition  to,  and not in lieu of,  any other  rights and
remedies available to the Company under the law or in equity.

         5.4      Construction and Enforceability.

                  5.4.1 If any of the covenants contained in Section 5.1 or 5.2,
or any part thereof, is hereafter construed to be invalid or unenforceable,  the
same shall not affect the remainder of the covenant or covenants, which shall be
given full effect, without regard to the invalid portions.

                  5.4.2 If any of the covenants contained in Section 5.1 or 5.2,
or any part thereof, is held to be unenforceable because of the duration of such
provision or the area covered  thereby,  the parties agree that the court making
such  determination  shall have the power to reduce the duration  and/or area of
such  provision  and,  in  its  reduced  form,  said  provision  shall  then  be
enforceable.

         5.5  Enforceability in Jurisdictions.  The parties hereto intend to and
hereby confer  jurisdiction  to enforce the covenants  contained in Sections 5.1
and 5.2 upon federal or state  courts or the courts of any foreign  jurisdiction
within the geographical scope of such covenants. In the event that the courts of
any one or more of such state, federal or foreign  jurisdictions shall hold such
covenants  wholly  unenforceable  by  reason  of the  breadth  of such  scope or
otherwise, it is the intention of the parties hereto that such determination not
bar or in any way affect the Company's right to the relief

                                     Page 6

Employment Agreement                                                Thomas Koshy

provided   above  in  the  courts  of  any  other  state,   federal  or  foreign
jurisdictions within the geographical scope of such covenants, as to breaches of
such covenants in such other  respective  jurisdictions,  the above covenants as
they relate to each state and foreign country being for this purpose,  severable
into diverse and independent covenants.

          5.6 Customer  Lists.  The Employee  recognizes and agrees (i) that all
existing  lists of customers  of the Company,  and all lists of customers of the
Company developed during the course of the Employee's employment by the Company,
are and  shall be the  sole  exclusive  property  of the  Company,  and that the
Employee neither has nor shall have any right,  title or interest therein;  (ii)
that such lists of customers  are and must  continue to be  confidential;  (iii)
that such lists are not readily  accessible to competitors of the Company;  (iv)
that the Company's  present and future  business is and will continue to be of a
type that customers will normally  patronize  principally  one concern;  and (v)
that the Company's  present and future business  relationship with its customers
is and will continue to be of a type which normally  continues unless interfered
with by others.

6.     Inventions and Patents.

         6.1  The  Employee  agrees  that  all  processes,   computer  software,
technologies  and  inventions   ("Inventions"),   including  new  contributions,
improvements,  ideas and  discoveries,  whether  patentable  or not,  conceived,
developed,  invented  or made by him  during  the term,  shall be the  exclusive
property  of the  Company and shall  belong to the  Company  provided  that such
Inventions  grew  out of the  Employee's  work  with the  Company  or any of its
subsidiaries  or  affiliates,   are  related  in  any  manner  to  the  business
(commercial  or  experimental)  of the  Company  or any of its  subsidiaries  or
affiliates or are conceived or made on the Company's time or with the use of the
Company's  facilities or materials.  The Employee  shall  further:  (i) promptly
disclose  such  Inventions to the Company;  (ii) assign to the Company,  without
additional  compensation,  all patent and other rights to such Inventions in the
United States and foreign  countries;  (iii) sign all papers  necessary to carry
out the foregoing; and (iv) give testimony in support of his inventorship.

         6.2 If  any  Invention  is  described  in a  patent  application  or is
disclosed to third parties,  directly or indirectly,  by the Employee within two
years  after the  termination  of his  employment  by the  Company,  it is to be
presumed  that the  Invention  was  conceived  or made  during the period of the
Employee's employment by the Company.

         6.3 The  Employee  agrees  that he will not  assert  any  rights to any
Invention  as  having  been  made or  acquired  by him prior to the date of this
Agreement, except for Inventions, if any, disclosed to the Company in Exhibit A.
All  Inventions,  Patents and ideas set forth in Exhibit A shall remain the sole
property of Employee.

7.  Intellectual  Property.  The  Company  shall  be the  sole  owner of all the
products and proceeds of the Employee's services hereunder,  including,  but not
limited to, all  materials,  ideas,  concepts,  formats,  suggestions,  computer
software, developments,

arrangements,  packages,  programs and other  intellectual  properties  that the
Employee may acquire,  obtain,  develop or create in connection  with and during
the term of the Employee's employment hereunder, free and clear of any claims by
the Employee (or anyone  claiming  under the  Employee) of any kind or character
whatsoever (other than the Employee's right to receive payments hereunder).  The
Employee  shall,  at the  request  of the  Company,  execute  such  assignments,
certificates  or other  instruments  as the  Company  may from time to time deem
necessary  or  desirable to evidence,  establish,  maintain,  perfect,  protect,
enforce or defend its right, or title and interest in or to any such properties.

8. Indemnification.  Where, in the determination of the Board of Directors,  the
Employee has acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interests of the Company,  the Company will indemnify
the Employee to the maximum  extent  permitted by  applicable  law,  against all
costs,  charges and expenses incurred or sustained by him in connection with any
action,  suit or  proceeding  to which he may be made a party by  reason  of his
being an  employee  of the  Company or an  officer,  director or employee of any
subsidiary  or affiliate of the Company or any other  corporation  for which the
Employee serves as an officer, director or employee, at the Company's request.

9.  Arbitration.  Any  controversy  or claim  arising out of or relating to this
Agreement,  or the breach thereof, shall be settled by arbitration in accordance
with the Rules of the American Arbitration  Association then pertaining,  in the
County  of San  Francisco,  State of  California,  and  judgment  upon the award
rendered  by the  Arbitrator  may be  entered in any court  having  jurisdiction
thereof.  The Arbitrator shall be deemed to possess the power to issue mandatory
orders and  restraining  orders in connection with such  arbitration;  provided,
however,  that  nothing in this  Article 9 shall be  construed so as to deny the
Company the right and power to seek and obtain  injunctive  relief in a court of
equity  for any  breach  or  threatened  breach  by the  Employee  of any of his
covenants contained in Articles 5, 6 and 7 hereof.

10. Attorneys Fees. In the event either party hereto commences any action,  suit
or other  proceeding  in law or in equity,  or any  arbitration,  to enforce the
provisions of this Agreement or for any remedy for breach of this Agreement, the
non-prevailing  party in such action shall pay the prevailing  party's costs and
expenses,  including  reasonable  attorneys'  fees  incurred  in such  action or
arbitration proceeding.
