                       CODE OF BUSINESS CONDUCT AND ETHICS

          (as approved by the Audit Committee of the Board of Directors
                              on November 18, 2003)


I.       INTRODUCTION

         This Code of Business  Conduct  and Ethics (the  "Code") is intended to
help ensure  compliance  with legal  requirements  and our standards of business
conduct. All officers,  directors and employees of Nanometrics Incorporated (the
"Company") are expected to read and understand this Code, uphold these standards
in day-to-day  activities,  comply with all applicable  policies and procedures,
and ensure that all agents, contractors and consultants are aware of, understand
and adhere to these standards.

         Because the  principles  described  in this Code are general in nature,
you also should review all applicable  Company  policies and procedures for more
specific  instruction  and  contact  the  Human  Resources  Department  or Legal
Department if you have any questions.

         Nothing in this Code,  in any company  policies and  procedures,  or in
other  related   communications  (verbal  or  written)  creates  or  implies  an
employment contract or term of employment.

         We are  committed to  continuously  reviewing and updating our policies
and procedures.  This Code,  therefore,  is subject to  modification.  This Code
supersedes all other such codes, policies, procedures, instructions,  practices,
rules or written or verbal representations to the extent they are inconsistent.

         Please sign the acknowledgment  form at the end of this Code and return
the form to the Human  Resources  Department  indicating that you have received,
read,  understand and agree to comply with the Code.  The signed  acknowledgment
form will be located in your personnel file.

II.      COMPLIANCE IS EVERYONE'S BUSINESS

         Ethical  business  conduct is critical to our business.  As an officer,
director and/or employee,  your responsibility is to respect and adhere to these
practices.  Many of these  practices  reflect legal or regulatory  requirements.
Violations of these laws and  regulations can create  significant  liability for
you, the Company, its officers, directors and employees.

         Part of your job and/or ethical  responsibility is to help enforce this
Code. You should be alert to possible  violations and promptly  report  possible
violations to the Human Resources  Department or the Legal Department.  You must
cooperate in any  internal or external  investigations  of possible  violations.
Reprisal, threats, retribution or retaliation against any person who has in good
faith  reported a violation or a suspected  violation of law, this Code or other
Company policies, or


                                      -2-


against any person who is assisting in any investigation or process with respect
to such a violation, is prohibited.

         Violations of law,  this Code, or other Company  policies or procedures
should be  promptly  reported  to the Human  Resources  Department  or the Legal
Department. Violations of law, this Code or other Company policies or procedures
can lead to disciplinary action, up to and including termination.

         In all cases, if you are unsure about the  appropriateness  of an event
or action,  please seek  assistance in  interpreting  the  requirements of these
practices by contacting the Legal Department.

III.     YOUR RESPONSIBILITIES TO THE COMPANY AND ITS SHAREHOLDERS

         A. General Standards of Conduct

         The  Company  expects  all  officers,  directors,   employees,  agents,
contractors  and  consultants to exercise good judgment to ensure the safety and
welfare of officers, directors,  employees, agents, contractors, and consultants
and to maintain a cooperative,  efficient,  positive,  harmonious and productive
work environment and business organization.  These standards apply while working
on our premises, at offsite locations where our business is being conducted,  at
Company-sponsored  business and social  events,  or at any other place where you
are a representative of the Company.  Officers,  directors,  employees,  agents,
contractors  or  consultants  who engage in misconduct or whose  performance  is
unsatisfactory  may  be  subject  to  corrective  action,  up to  and  including
termination.  You should also be aware of our company policies for more detailed
specific situations.

         B. Applicable Laws

         All Company officers,  directors,  employees,  agents,  contractors and
consultants  must  comply  with all  applicable  laws,  regulations,  rules  and
regulatory  orders.  Company employees located outside of the United States must
comply with laws, regulations, rules and regulatory orders of the United States,
including the Foreign Corrupt  Practices Act and the U.S. Export Control Act, in
addition to applicable  local laws.  Each officer,  director,  employee,  agent,
contractor and consultant must acquire appropriate knowledge of the requirements
relating  to his or her  duties  sufficient  to enable  him or her to  recognize
potential  dangers and to know when to seek advice from the Legal  Department on
specific Company policies and procedures. Violations of laws, regulations, rules
and orders may subject the officer,  director,  employee,  agent,  contractor or
consultant to individual  criminal or civil liability,  as well as to discipline
by the Company. Such individual violations also may subject the Company to civil
or criminal liability or the loss of business.

         C. Conflicts of Interest

         Each of us has a  responsibility  to the Company,  our shareholders and
each  other to avoid any  actual  or  apparent  conflict  of  interest  whenever
possible.  Although  this duty does not  prevent us from  engaging  in  personal
transactions  and  investments,  it does demand that we avoid situations where a
conflict of interest might occur or appear to occur. The Company recognizes that
certain potential  conflicts of interest may arise from time to time that may be
unavoidable.  For this  reason,


                                      -3-


all potential conflicts of interest must be reported to the subject individual's
supervisor and to the Company's Chief Financial Officer for review and approval.

         A conflict of interest  exists  where the  interests or benefits of one
person or entity conflict with the interests or benefits of the Company,  unless
expressly  approved  by the  Company.  While  it is  difficult  to  exhaustively
identify what  constitutes  a conflict of interest,  set forth below are general
examples  of  situations  that could  create a conflict  of  interest.  Examples
include:

                  (i) Employment/Outside  Employment. You are expected to devote
your full attention to the business interests of the Company. You are prohibited
from  engaging  in  any  activity  that  interferes  with  your  performance  or
responsibilities  to the Company or otherwise is in conflict with or prejudicial
to the Company.  Our policies prohibit any employee from accepting  simultaneous
employment with a Company supplier,  customer,  developer or competitor, or from
taking part in any activity that enhances or supports a  competitor's  position.
In addition,  you must  disclose to the Company any interest  that you have that
may  conflict  with the  business  of the  Company.  If you  have any  questions
regarding  this  requirement,  you should  contact your  supervisor or the Human
Resources Department.

                  (ii)  Outside  Directorships.  It is a conflict of interest to
serve as a director of any company that competes with the Company.  Although you
may serve as a director of a Company  supplier,  customer,  developer,  or other
business  partner,  our policy  requires that you first obtain approval from the
Company's Chief Financial Officer before accepting any such  directorship.  Such
approval  may be  conditioned  upon the  completion  of specified  actions.  Any
compensation you receive should be commensurate to your responsibilities.

                  (iii) Business Interests.  If you are considering investing in
a Company customer, supplier, developer or competitor, you first must take great
care to ensure that these investments do not compromise your responsibilities to
the Company. Many factors should be considered in determining whether a conflict
exists,  including  the size and  nature  of the  investment,  your  ability  to
influence the Company's  decisions,  your access to confidential  information of
the Company or of the other company and the nature of the  relationship  between
the Company and the other company.

                  (iv)  Related  Parties.  As a general  rule,  you should avoid
conducting  Company  business with a relative or  significant  other,  or with a
business  in  which  a  relative  or  significant  other  is  associated  in any
significant role. Relatives include spouses, sisters, brothers, daughters, sons,
mothers,  fathers,  grandparents,  aunts, uncles, nieces, nephews, cousins, step
relatives,  and in-laws.  Significant others include persons living in a spousal
(including same sex) or familial fashion with an employee.

         If such a related  party  transaction  is  unavoidable,  you must fully
disclose the nature of the related  party  transaction  to the  Company's  Chief
Financial  Officer.  If  determined  to be  material to the Company by the Chief
Financial  Officer,  the Company's  Audit  Committee  must review and approve in
writing in advance such related party transactions.  Any dealings with a related
party must be conducted in such a way that no preferential treatment is given to
the related party.


                                      -4-


         The Company  discourages  the  employment of relatives and  significant
others in positions or assignments  within the same department and prohibits the
employment of such individuals in positions that have a financial  dependence or
influence (e.g., an auditing or control relationship or a supervisor/subordinate
relationship).  If a question  arises about whether a relationship is covered by
this policy,  the Human  Resources  Department is  responsible  for  determining
whether an applicant's or transferee's  acknowledged  relationship is covered by
this  policy.   Willful  withholding  of  information   regarding  a  prohibited
relationship/reporting  arrangement may be subject to corrective  action,  up to
and  including  termination.  If a  prohibited  relationship  exists or develops
between two employees,  the employee in the senior  position must inform his/her
supervisor.  The Company  retains the prerogative to separate the individuals at
the  earliest  possible  time,  either by  reassignment  or by  termination,  if
necessary.

                  (v)  Interested  Party  Transactions.  In general,  you should
avoid situations that give rise to apparent  conflicts  between your own private
interests and the  interests of the Company.  An  interested  party  transaction
exists  if  an  officer,   employee  or  director  would  benefit,  directly  or
indirectly,  from the payment of monies or other consideration by the Company to
a party or entity  in which  such  person  has a direct  or  indirect  pecuniary
interest.

         If you have any concerns about a proposed  transaction  that may appear
to be such an  interested  party  transaction,  you  should  consult  the  Legal
Department immediately.

         D. Corporate Opportunities

         Employees,  officers  and  directors  may not  exploit  for  their  own
personal gain  opportunities  that are  discovered  through the use of corporate
property,  information or position  unless the opportunity is disclosed fully in
writing to the Company's Board of Directors and the Board of Directors  declines
to pursue such opportunity.

         E. Protecting the Company's Confidential Information

         The  Company's  confidential  information  is  a  valuable  asset.  The
Company's confidential information includes product architectures; source codes;
product  plans  and road  maps;  names  and  lists of  customers,  dealers,  and
employees;  and financial  information.  This information is the property of the
Company and may be protected by patent,  trademark,  copyright  and trade secret
laws. All confidential  information  must be used for Company business  purposes
only. Every officer,  director,  employee,  agent, contractor or consultant must
safeguard it. THIS RESPONSIBILITY  INCLUDES NOT DISCLOSING COMPANY  CONFIDENTIAL
INFORMATION,  SUCH AS INFORMATION  REGARDING THE COMPANY'S  PRODUCTS OR BUSINESS
OVER THE INTERNET.  You also are responsible  for properly  labeling any and all
documentation  shared  with  or  correspondence  sent  to  the  Company's  Legal
Department or outside counsel as  "Attorney-Client  Privileged." This obligation
extends to  confidential  information  of third  parties  that the  Company  has
rightfully received under  Non-Disclosure  Agreements.  See the Company's policy
dealing with Handling  Confidential  Information  of Others set forth in Section
IV.D of this Code.


                                      -5-


                  (i) Proprietary Information and Invention Agreement.  When you
joined the Company, you signed an agreement to protect and hold confidential the
Company's proprietary information.  This agreement remains in effect for as long
as you work for the  Company  and  after  you  leave  the  Company.  Under  this
agreement, you may not disclose the Company's confidential information to anyone
or use it to benefit  anyone  other than the Company  without the prior  written
consent of an authorized Company officer.

                  (ii)  Disclosure  of  Company  Confidential  Information.   To
further the Company's business,  from time to time our confidential  information
may be disclosed to potential business partners. Such confidential  information,
however,  never should be disclosed without carefully  considering its potential
benefits and risks.  If you determine,  in  consultation  with your manager,  if
applicable,  and  other  appropriate  Company  management,  that  disclosure  of
confidential   information  is  necessary,  you  then  must  contact  the  Legal
Department  to ensure that an  appropriate  written  nondisclosure  agreement is
signed  prior  to  the  disclosure.   The  Company  has  standard  nondisclosure
agreements  suitable  for most  disclosures.  You must not sign a third  party's
nondisclosure   agreement   or  accept   changes  to  the   Company's   standard
nondisclosure  agreements  without  review and approval by the  Company's  Legal
Department. In addition, all Company materials that contain Company confidential
information,  including  presentations,  must be  reviewed  and  approved by the
Company's  Legal  Department  prior  to  publication  or use.  Furthermore,  any
employee  publication  or publicly  made  statement  that might be  perceived or
construed as attributable  to the Company,  made outside the scope of his or her
employment with the Company, must be reviewed and approved in writing in advance
by the  Company's  Legal  Department  and must  include the  Company's  standard
disclaimer  that  the  publication  or  statement  represents  the  views of the
specific author and not of the Company.

                  (iii) Requests by Regulatory Authorities.  The Company and its
officers,  directors,   employees,  agents,  contractors  and  consultants  must
cooperate with  appropriate  government  inquiries and  investigations.  In this
context,  however,  it also is  important  to  protect  the legal  rights of the
Company with respect to its confidential  information.  All government  requests
for information,  documents or investigative  interviews must be referred to the
Company's Legal  Department.  No financial  information may be disclosed without
the prior approval of the Chief Financial Officer.

                  (iv)  Company   Spokespeople.   Specific  policies  have  been
established  regarding  who may  communicate  information  to the  press and the
financial analyst community. All inquiries or calls from the press and financial
analysts  should be referred  to the Chief  Financial  Officer.  The Company has
designated its Chief Executive  Officer and Chief Financial  Officer as official
Company spokespeople for financial matters. The Company has designated its Chief
Executive  Officer  or  Marketing  and  Sales  Department  as  official  Company
spokespeople  for  marketing,   technical  and  other  such  information.  These
designees  are the only people who may  communicate  with the press on behalf of
the Company.

         F. Obligations Under Securities Laws-"Insider" Trading

         Obligations  under the U.S.  securities laws apply to everyone.  In the
normal course of business, officers,  directors,  employees, agents, contractors
and  consultants  of the  Company  may  come  into  possession  of  significant,
sensitive  information.  This  information is the property of the


                                      -6-


Company -- you have been entrusted with it. You may not profit from it by buying
or selling  securities  yourself,  or passing  on the  information  to others to
enable them to profit or for them to profit on your behalf.  The purpose of this
policy is both to inform  you of your  legal  responsibilities  and also to make
clear to you that the misuse of  sensitive  information  is  contrary to Company
policy and U.S. securities laws.

         Insider trading is a crime,  penalized by fines of up to $5,000,000 and
20 years in jail for  individuals.  In  addition,  the  Securities  and Exchange
Commission  may seek the  imposition of a civil penalty of up to three times the
profits  made or losses  avoided  from the  trading.  Insider  traders also must
disgorge any profits made.  Finally,  insider  traders may be subjected to civil
liability in private lawsuits.

         Employers  and  other  controlling   persons   (including   supervisory
personnel) also are at risk under U.S. securities laws. Controlling persons may,
among other things,  face  penalties of the greater of $5,000,000 or three times
the profits made or losses avoided by the trader if they recklessly fail to take
preventive steps to control insider trading.

         Thus, it is important both to you and the Company that  insider-trading
violations  do not occur.  You should be aware  that stock  market  surveillance
techniques  are becoming  increasingly  sophisticated,  and the chance that U.S.
federal  or  other  regulatory   authorities  will  detect  and  prosecute  even
small-level trading is significant. Insider trading rules are strictly enforced,
even in instances when the financial transactions seem small. You should contact
the Chief  Financial  Officer  or the Legal  Department  if you are unsure as to
whether or not you are free to trade.

         The  Company  has  imposed a  trading  blackout  period  on  directors,
executive  officers and certain  designated  employees  who, as a consequence of
their  position  with the  Company,  are more  likely to be exposed to  material
nonpublic information about the Company. These directors, executive officers and
employees  generally  may not trade in Company  securities  during the  blackout
period.

         For more details,  and to determine if you are restricted  from trading
during trading blackout  periods,  you should review the Company's Stock Trading
Policy  for  Insiders.  You can  request  a copy of this  policy  from the Legal
Department.

         G. Use of Company's Assets

                  (i)  General.   Protecting  the  Company's  assets  is  a  key
responsibility  of every  officer,  director,  employee,  agent,  contractor and
consultant.  Care should be taken to ensure that assets are not misappropriated,
loaned to others, or sold or donated,  without  appropriate  authorization.  All
Company officers, directors,  employees, agents, contractors and consultants are
responsible  for the proper use of Company assets and must safeguard such assets
against loss,  damage,  misuse or theft.  Company equipment and assets are to be
used for Company business purposes only. Officers, directors, employees, agents,
contractors and consultants may not use Company assets for personal use, nor may
they  allow  any other  person to use  Company  assets.  Employees  who have any
questions  regarding  this  policy  should  bring them to the  attention  of the
Company's Human Resources Department.


                                      -7-


                  (ii)  Physical  Access  Control.  The  Company  has  and  will
continue  to  develop  procedures  covering  physical  access  control to ensure
privacy  of   communications,   maintenance  of  the  security  of  the  Company
communication  equipment,  and safeguard  Company assets from theft,  misuse and
destruction.  You are  personally  responsible  for complying  with the level of
access  control that has been  implemented  in the facility  where you work on a
permanent  or temporary  basis.  You must not defeat or cause to be defeated the
purpose for which the access control was implemented.

                  (iii) Electronic  Usage. The purpose of this policy is to make
certain that officers, directors, employees, agents, contractors and consultants
utilize electronic  communication  devices in a legal,  ethical, and appropriate
manner.  This policy  addresses  the  Company's  responsibilities  and  concerns
regarding  the fair and  proper  use of all  electronic  communications  devices
within  the  organization,  including  computers,  e-mail,  connections  to  the
Internet,  intranet and extranet and any other public or private networks, voice
mail,  video  conferencing,  facsimiles,  and telephones.  Posting or discussing
information  concerning  the  Company's  products or  business  on the  Internet
without the prior written consent of the Company's  Chief  Financial  Officer is
prohibited.  Any  other  form of  electronic  communication  used  by  officers,
directors,  employees,  agents,  contractors and consultants currently or in the
future also is intended to be encompassed  under this policy. It is not possible
to  identify  every  standard  and  rule  applicable  to the  use of  electronic
communications devices. Officers, directors,  employees, agents, contractors and
consultants,  therefore, are encouraged to use sound judgment whenever using any
feature of our communications systems.

         H. Maintaining and Managing Records

         The  purpose of this  policy is to set forth and  convey the  Company's
business and legal  requirements  in managing  records,  including  all recorded
information  regardless  of medium or  characteristics.  Records  include  paper
documents, CDs, computer hard disks, email, floppy disks, microfiche,  microfilm
or all other media. The Company is required by local,  state,  federal,  foreign
and other  applicable  laws, rules and regulations to retain certain records and
to follow  specific  guidelines  in managing  its  records.  Civil and  criminal
penalties for failure to comply with such guidelines can be severe for officers,
directors,  employees,  agents,  contractors,  consultants and the Company,  and
failure  to  comply  with  such  guidelines  may  subject  such  individuals  to
disciplinary  action, up to and including  termination of employment or business
relationship at the Company's sole discretion.

         I. Payment Practices

                  (i) Accounting  Practices.  The Company's  responsibilities to
its shareholders  and the investing  public require that all transactions  fully
and accurately be recorded in the Company's books and records in compliance with
all applicable laws. False or misleading entries, unrecorded funds or assets, or
payments without appropriate supporting  documentation and approval strictly are
prohibited  and  violate   Company  policy  and  the  law.   Additionally,   all
documentation  supporting a transaction fully and accurately should describe the
nature of the transaction and be processed in a timely fashion.


                                      -8-


                  (ii) Political  Contributions.  The Company reserves the right
to communicate its position on important issues to elected  representatives  and
other government officials.  It is the Company's policy fully to comply with all
local, state, federal,  foreign and other applicable laws, rules and regulations
regarding  political  contributions.  Under no  circumstances  may the Company's
funds or assets must not be used for, or be contributed to, political  campaigns
or political practices without the prior written approval of the Company's Chief
Financial Officer and, if required, the Board of Directors.

         J. Foreign Corrupt  Practices  ActThe Company  requires full compliance
with the Foreign  Corrupt  Practices  Act (the  "FCPA") by all of its  officers,
directors, employees, agents, contractors and consultants.

         The  anti-bribery  and  corrupt  payment  provisions  of the FCPA  make
illegal any corrupt offer, payment,  promise to pay, or authorization to pay any
money,  gift,  or  anything  of value to any  foreign  official,  or any foreign
political party,  candidate or official,  for the purpose of influencing any act
or failure to act, in the official capacity of that foreign official or party or
inducing the foreign  official or party to use influence to affect a decision of
a foreign  government  or  agency,  in order to obtain  or retain  business  for
anyone, or direct business to anyone.

         All Company officers,  directors,  employees,  agents,  contractors and
consultants  whether located in the United States or abroad, are responsible for
FCPA compliance and the procedures to ensure FCPA  compliance.  All managers and
supervisory personnel are expected to monitor continued compliance with the FCPA
to ensure compliance with the highest moral, ethical and professional  standards
of the Company.

         K. Export Controls

         A number of countries  maintain  controls on the  destinations to which
products or software may be exported.  Some of the strictest export controls are
maintained  by the United  States  against  countries  that the U.S.  government
considers  unfriendly  or  as  supporting   international  terrorism.  The  U.S.
regulations  are complex and apply both to exports from the United States and to
exports  of  products  from  other   countries,   when  those  products  contain
U.S.-origin  components or technology.  Software created in the United States is
subject to these  regulations  even if duplicated and packaged  abroad.  In some
circumstances,  an oral presentation  containing  technical data made to foreign
nationals in the United  States may  constitute a controlled  export.  The Legal
Department  can provide  you with  guidance on which  countries  are  prohibited
destinations for Company products or whether a proposed  technical  presentation
to foreign nationals may require a U.S. Government license.

         L. Public Disclosure of Information

         The federal  securities  laws  require the Company to disclose  certain
information in various  reports that the Company must file with or submit to the
SEC.  In   addition,   from  time  to  time  the  Company   makes  other  public
communications, such as issuing press releases.

         The  Company  expects  its Chief  Executive  Officer,  Chief  Financial
Officer and all other officers,  directors and employees who are involved in the
preparation  of SEC  reports  or  other  public


                                      -9-


documents to ensure that the  information  disclosed in those documents is full,
fair, accurate, timely and understandable.

         Moreover,  if any officer,  director or employee  becomes  aware of any
material  information  that you believe should be disclosed to the public in the
Company's  reports filed with the SEC, it is your  responsibility  to bring such
information to the attention of the Chief Financial Officer or any member of the
Legal  Department.  To the extent that you reasonably  believe that questionable
accounting or auditing conduct or practices have occurred or are occurring,  you
should  report  those  concerns  to the  Chief  Financial  Officer  or the Legal
Department.

IV.      RESPONSIBILITIES TO OUR CUSTOMERS AND OUR SUPPLIERS

         A. Customer Relationships

         If your  position  puts you in contact  with any Company  customers  or
potential  customers,  it is critical for you to remember that you represent the
Company to the people with whom you are  dealing.  Act in a manner that  creates
value for our customers and helps to build a relationship  based upon trust. The
Company and its employees have provided products and services for many years and
have built up significant  goodwill over that time.  This goodwill is one of our
most important assets and the Company officers,  directors,  employees,  agents,
contractors and consultants must act to preserve and enhance our reputation.

         B. Payments or Gifts from Others

         Under no  circumstances  may officers,  directors,  employees,  agents,
contractors  or  consultants  accept any  offer,  payment,  promise  to pay,  or
authorization  to pay any money,  gift,  or  anything  of value from  customers,
vendors,   consultants,   etc.  that  is  perceived  as  intended,  directly  or
indirectly,  to influence any business decision,  any act or failure to act, any
commitment of fraud, or opportunity for the commission of any fraud. Inexpensive
gifts, infrequent business meals, celebratory events and entertainment, provided
that they are not  excessive  or create an  appearance  of  impropriety,  do not
violate this policy.  Questions  regarding whether a particular  payment or gift
violates  this  policy  are to be  directed  to  Human  Resources  or the  Legal
Department.

         C. Publications of Others

         The  Company  subscribes  to  many  publications  that  help  officers,
employees,  agents, contractors and consultants better perform their jobs. These
publications  include  newsletters,  reference works, online reference services,
magazines,  books, and other digital and printed works.  Copyright law generally
protects these works, and their unauthorized copying and distribution constitute
copyright infringement.  You first must obtain the consent of the publisher of a
publication  before copying  publications or significant  parts of them. When in
doubt about whether you may copy a publication, consult the Legal Department.

         D. Handling the Confidential Information of Others

         The  Company  has  many  kinds  of  business  relationships  with  many
companies and  individuals.  Sometimes  companies or individuals  will volunteer
confidential  information  about their


                                      -10-


products  or  business  plans to induce  the  Company  to enter  into a business
relationship.  At  other  times,  we may  request  that a  third  party  provide
confidential  information to permit the Company to evaluate a potential business
relationship with that party. Whatever the situation,  we must take special care
to handle the  confidential  information of others  responsibly.  We handle such
confidential  information  in  accordance  with our  agreements  with such third
parties.

                  (i)   Appropriate   Nondisclosure   Agreements.   Confidential
information may take many forms. An oral presentation  about a company's product
development  plans may  contain  protected  trade  secrets.  A customer  list or
employee list may be a protected  trade secret.  A demo of an alpha version of a
company's  new  software may contain  information  protected by trade secret and
copyright laws.

         You never should  accept  information  offered by a third party that is
represented as confidential,  or which appears from the context or circumstances
to be  confidential,  unless an  appropriate  nondisclosure  agreement  has been
signed with the party offering the information. THE LEGAL DEPARTMENT CAN PROVIDE
NONDISCLOSURE  AGREEMENTS TO FIT ANY  PARTICULAR  SITUATION AND WILL  COORDINATE
APPROPRIATE  EXECUTION OF SUCH AGREEMENTS ON BEHALF OF THE COMPANY. Even after a
nondisclosure  agreement  is in place,  you only should  accept the  information
necessary  to  accomplish  the  purpose  of  receiving  it,  such as a  decision
regarding  whether  to  proceed  in  negotiating  a deal.  If more  detailed  or
extensive  confidential  information is offered and it is not necessary for your
immediate purposes, it should be refused.

                  (ii)   Need-to-Know.   Once  a  third   party's   confidential
information has been disclosed to the Company, we have an obligation to abide by
the terms of the relevant nondisclosure agreement, limit its use to the specific
purpose for which it was  disclosed  and  disseminate  it only to other  Company
employees  with a  need  to  know  the  information.  Every  officer,  director,
employee,  agent,  contractor  and consultant  involved in a potential  business
relationship  with a third  party  must  understand  and  strictly  observe  the
restrictions on the use and handling of confidential information. When in doubt,
consult the Legal Department.

                  (iii)  Notes and  Reports.  When  reviewing  the  confidential
information of a third party under a nondisclosure  agreement,  it is natural to
take notes or prepare  reports  summarizing the results of the review and, based
partly on those notes or reports, to draw conclusions about the suitability of a
business  relationship.  Notes or reports,  however,  can  include  confidential
information  disclosed  by the other party and so only  should be retained  long
enough to  complete  the  evaluation  of the  potential  business  relationship.
Subsequently,  they  either  should be  destroyed  or  turned  over to the Legal
Department for safekeeping or destruction.  These materials should be treated as
any  other  disclosure  of  confidential   information  is  treated:  marked  as
confidential  and  distributed  only to those the Company  officers,  directors,
employees, agents, contractors or consultants with a need to know.

                  (iv)  Competitive  Information.  You never  should  attempt to
obtain a competitor's confidential information by improper means, and you should
especially never contact a competitor regarding their confidential  information.
While the Company may, and does,  employ  former


                                      -11-


employees of  competitors,  we recognize  and respect the  obligations  of those
employees not to use or disclose the  confidential  information  of their former
employers.

         E. Selecting Suppliers

         The Company's suppliers make significant  contributions to our success.
To create an environment  where our suppliers have an incentive to work with the
Company,  they must be  confident  that they will be treated  lawfully and in an
ethical  manner.  The Company's  policy is to purchase  supplies  based on need,
quality, service, price, terms and conditions. The Company's policy is to select
significant  suppliers or enter into significant  supplier  agreements through a
competitive  bid  process  where  possible.  Under no  circumstances  should any
officer,  director,  employee, agent, contractor or consultant attempt to coerce
suppliers in any way.

         F. Government Relations

         It is the Company's policy to fully comply with all applicable laws and
regulations  governing contact and dealings with government employees and public
officials,  and to adhere to high ethical, moral and legal standards of business
conduct.  This policy includes strict compliance with all local, state, federal,
foreign  and  other  applicable  laws,  rules and  regulations.  If you have any
questions concerning government relations you should contact the Company's Legal
Department.

         G. Lobbying

         Officers,  directors,  employees,  agents,  contractors  or consultants
whose work  requires  lobbying  communication  with any member or  employee of a
legislative body or with any government  official or employee in the formulation
of legislation  must have prior written approval of such activity from the Legal
Department.  Activity covered by this policy includes  meetings with legislators
or  members  of  their  staffs  or  with  senior  executive  branch   officials.
Preparation,  research, and other background activities that are done in support
of  lobbying  communication  also  are  covered  by  this  policy  even  if  the
communication ultimately is not made.

         H. Government Contracts

         It is the Company's policy to fully comply with all applicable laws and
regulations  that  apply to  government  contracting.  It also is  necessary  to
strictly  adhere to all terms and conditions of any contract with local,  state,
federal, foreign or other applicable governments. The Company's Legal Department
must review and approve all contracts with any government entity.

         I. Free and Fair Competition

         Most countries have well-developed  bodies of law designed to encourage
and protect free and fair competition.  The Company is committed to obeying both
the letter and spirit of these  laws.  The  consequences  of not doing so can be
severe for all of us.

         These  laws  often  regulate  the  Company's   relationships  with  its
distributors,  resellers,  dealers,  and customers.  Competition  laws generally
address the following areas: pricing practices (including price discrimination),
discounting,  terms  of  sale,  credit  terms,  promotional  allowances,  secret


                                      -12-


rebates,   exclusive   dealerships  or   distributorships,   product   bundling,
restrictions  on  carrying  competing  products,  termination,  and  many  other
practices.

         Competition  laws also govern,  usually quite  strictly,  relationships
between  the Company  and its  competitors.  As a general  rule,  contacts  with
competitors should be limited and always should avoid subjects such as prices or
other  terms  and  conditions  of  sale,  customers,  and  suppliers.  Officers,
directors,  employees, agents, contractors or consultants of the Company may not
knowingly make false or misleading  statements  regarding its competitors or the
products  of  its  competitors,   customers  or  suppliers.  Participating  with
competitors in a trade association or in a standards creation body is acceptable
when the association has been properly  established,  has a legitimate  purpose,
and has limited its activities to that purpose.

         No officer,  director,  employee, agent, contractor or consultant shall
at any time or under any circumstances enter into an agreement or understanding,
written or oral,  express or implied,  with any  competitor  concerning  prices,
discounts,  other terms or conditions of sale, profits or profit margins, costs,
allocation   of  product  or  geographic   markets,   allocation  of  customers,
limitations  on production,  boycotts of customers or suppliers,  or bids or the
intent to bid or even discuss or exchange information on these subjects. In some
cases, legitimate joint ventures with competitors may permit exceptions to these
rules,   as  may  bona  fide   purchases   from  or  sales  to   competitors  on
non-competitive  products,  but the Company's  Legal  Department must review all
such proposed  ventures in advance.  These  prohibitions are absolute and strict
observance  is  required.   Collusion  among  competitors  is  illegal  and  the
consequences of a violation are severe.

         Although the spirit of these laws, known as "antitrust," "competition,"
or "consumer  protection" or unfair competition laws, is straightforward,  their
application to particular  situations  can be quite complex.  To ensure that the
Company fully complies with these laws, each of us should have a basic knowledge
of them and  should  involve  our Legal  Department  early on when  questionable
situations arise.

         J. Industrial Espionage

         It is the Company's policy to lawfully compete in the marketplace. This
commitment to fairness  includes  respecting the rights of our  competitors  and
abiding by all applicable  laws in the course of competing.  The purpose of this
policy is to maintain the  Company's  reputation as a lawful  competitor  and to
help ensure the integrity of the  competitive  marketplace.  The Company expects
its competitors to respect our rights to lawfully compete in the marketplace and
we  must  equally  respect  their  rights  to do  the  same.  Company  officers,
directors,  employees,  agents,  contractors  and  consultants  may not steal or
unlawfully use the information,  material,  products,  intellectual property, or
proprietary  or  confidential   information  of  anyone   including   suppliers,
customers, business partners or competitors.

V.       WAIVERS

         Any waiver of any  provision of this Code for a member of the Company's
Board of Directors  or an  executive  officer must be approved in writing by the
Company's Board of Directors and promptly disclosed. Any waiver of any provision
of this Code with respect to any other officer,


                                      -13-


employee,  agent,  contractor or  consultant  must be approved in writing by the
Company's Chief Financial Officer.

VI.      DISCIPLINARY ACTIONS

         The matters  covered in this Code are of the utmost  importance  to the
Company,  its shareholders and its business  partners,  and are essential to the
Company's  ability to conduct its business in accordance with its stated values.
We expect all of our officers,  directors,  employees,  agents,  contractors and
consultants  to adhere to these  rules in  carrying  out  their  duties  for the
Company.

         The Company will take appropriate action against any officer, director,
employee,  agent,  contractor or  consultant  whose actions are found to violate
these  policies or any other policies of the Company.  Disciplinary  actions may
include  immediate  termination  of employment or business  relationship  at the
Company's  sole  discretion.  If the  Company has  suffered a loss,  then it may
pursue its remedies  against the  individuals or entities  responsible.  If laws
have been violated,  then the Company will fully  cooperate with the appropriate
authorities.


                                      -14-
