                  (2)  The  Company's  Quarterly  Report  on Form  10-Q  for the
         quarter  ended  June 29,  1997  filed  pursuant  to  Section  13 of the

                  (3)  The  description  of the  Company's  Common  Stock  to be
         offered hereby which is contained in its Registration Statement on Form
         8-B filed  September 24, 1987, as amended by the Company's Form 8 dated

Item 5.       Interests of Named Experts and Counsel.

              None.

Item 6.       Indemnification of Directors and Officers.

              Section  145 of the  Delaware  General  Corporation  Law permits a
corporation to grant indemnification to directors,  officers and other agents in
terms sufficiently broad to permit  indemnification  under certain circumstances
for liabilities,  including expenses,  arising in connection with the Securities
Act of 1933,  as amended.  Pursuant to the Bylaws of the Company,  directors and
officers of the Company are  indemnified to the fullest extent  permitted by law
against all expenses (including attorneys' fees), judgments, fines or settlement
amounts  incurred  or paid by them in any action or  proceeding,  including  any
action by or on behalf of the Company, on account of their service as an officer
or director of the Company. The Bylaws further provide that the rights conferred
under such Bylaws shall not be deemed exclusive of any other right to which such
persons may be entitled under Delaware  General  Corporation  Law, the Company's
Certificate of  Incorporation,  any bylaw,  agreement,  vote of  stockholders or
disinterested directors or otherwise.  The Restated Certificate of Incorporation
of the Company, as amended,  precludes, with certain exceptions, the Company and
its  stockholders  from recovering  monetary damages from directors for business
decisions that breach such directors' fiduciary duty.

              The  Company  also  maintains  directors  and  officers  insurance
policies which insure directors and officers against losses arising from certain
wrongful acts in their  official  capacities and reimburses the Company for such
loss for which the Company has lawfully  indemnified the directors and officers.
In addition, the Company has entered into an Indemnification Agreement with each
of its directors and officers  whereby the Company has agreed to indemnify  each
director  and officer  from and against any and all  expenses,  losses,  claims,
damages and liabilities incurred by such director or officer while acting in his
or her official capacity.

              The Underwriting  Agreement among the Company and the underwriters
of the Company's May 1995 public offering contains certain  provisions  pursuant
to which the  underwriters  may,  under  certain  circumstances,  indemnify  the
directors and officers of the Company. Directors and officers of the Company may
also  be  indemnified  in  certain   circumstances  under  the  terms  of  other
underwriting  agreements  entered into by the Company in  connection  with prior
public offerings.

Item 7.       Exemption from Registration Claimed.

              Not applicable.

Item 8.       Exhibits.

              See Index to Exhibits.

Item 9.       Undertakings.

              (a) The undersigned Registrant hereby undertakes:

                  (1)      To file,  during any period in which  offers or sales
                           are being made,  a  post-effective  amendment to this
                           Registration Statement:

                           (i)      to  include  any   prospectus   required  by
                                    Section 10(a)(3) of the Securities Act;

                           (ii)     to  reflect in the  prospectus  any facts or
                                    events  arising after the effective  date of
                                    the  Registration  Statement  (or  the  most
                                    recent  post-effective   amendment  thereof)
                                    which,  individually  or in  the  aggregate,
                                    represent  a   fundamental   change  in  the
                                    information  set  forth in the  Registration
                                    Statement.  Notwithstanding  the  foregoing,
                                    any   increase  or  decrease  in  volume  of
                                    securities  offered  (if  the  total  dollar
                                    value of securities offered would not exceed
                                    that which was registered) and any deviation
                                    from  the low or high  end of the  estimated
                                    maximum  offering  range may be reflected in
                                    the  form  of  prospectus   filed  with  the
                                    Securities and Exchange  Commission pursuant
                                    to Rule  424(b)  if, in the  aggregate,  the
                                    changes  in volume  and price  represent  no
                                    more than a 20 percent change in the maximum
                                    aggregate  offering  price  set forth in the
                                    "Calculation of  Registration  Fee" table in
                                    the effective Registration Statement;

                           (iii)    to include  any  material  information  with
                                    respect  to the  plan  of  distribution  not
                                    previously  disclosed  in  the  Registration
                                    Statement  or any  material  change  to such
                                    information in the Registration Statement;

                           provided,  however,  that  paragraphs  (a)(1)(i)  and
                           (a)(1)(ii) do not apply if the Registration Statement
                           is on  Form  S-3,  Form  S-8 or  Form  F-3,  and  the
                           information    required   to   be   included   in   a
                           post-effective   amendment  by  those  paragraphs  is
                           contained in periodic reports filed by the Registrant
                           pursuant  to  Section  13 or  Section  15(d)  of  the
                           Exchange  Act that are  incorporated  by reference in
                           the Registration Statement.

                  (2)      That,  for the purpose of  determining  any liability
                           under the  Securities  Act, each such  post-effective
                           amendment  shall be deemed  to be a new  registration
                           statement relating to the securities offered therein,
                           and the  offering  of such  securities  at that  time
                           shall be deemed to be the initial bona fide  offering
                           thereof.

                  (3)      To   remove   from   registration   by   means  of  a
                           post-effective  amendment any of the securities being
                           registered  which remain unsold at the termination of
                           the offering.

              (b) The undersigned Registrant hereby further undertakes that, for
                  purposes of  determining  any liability  under the  Securities
                  Act, each filing of the Registrant's annual report pursuant to
                  Section 13(a) or Section 15(d) of the Exchange Act (and, where
                  applicable,  each filing of an employee  benefit plan's annual
                  report  pursuant to Section 15(d) of the Exchange Act) that is
                  incorporated by reference in the Registration  Statement shall
                  be deemed to be a new registration  statement  relating to the
                  securities   offered   therein,   and  the  offering  of  such
                  securities at that time shall be deemed to be the initial bona
                  fide offering thereof.

              (c) Insofar as indemnification  for liabilities  arising under the
                  Securities  Act may be  permitted to  directors,  officers and
                  controlling   persons  of  the  Registrant   pursuant  to  the
                  foregoing  provisions,  or otherwise,  the Registrant has been
                  advised  that in the opinion of the  Securities  and  Exchange
                  Commission  such  indemnification  is against public policy as
                  expressed   in  the   Securities   Act  and   is,   therefore,
                  unenforceable.  In the event that a claim for  indemnification
                  against  such  liabilities  (other  than  the  payment  by the
                  Registrant of expenses incurred or paid by a director, officer
                  or  controlling  person of the  Registrant  in

                  the successful  defense of any action,  suit or proceeding) is
                  asserted by such director,  officer or  controlling  person in
                  connection   with  the  securities   being   registered,   the
                  Registrant  will,  unless in the  opinion of its  counsel  the
                  matter has been settled by controlling precedent,  submit to a
                  court of appropriate  jurisdiction  the question  whether such
                  indemnification by it is against public policy as expressed in
                  the   Securities  Act  and  will  be  governed  by  the  final
                  adjudication of such issue.

                       INTEGRATED DEVICE TECHNOLOGY, INC.

                             1994 STOCK OPTION PLAN

                             As Adopted May 3, 1994
                      and as Amended through April 29, 1997



                1. PURPOSE.  The purpose of the Plan is to provide incentives to
attract,  retain and  motivate  eligible  persons  whose  present and  potential
contributions  are  important  to  the  success  of  the  Company,  its  Parent,
Subsidiaries  and Affiliates,  by offering them an opportunity to participate in
the Company's future  performance  through awards of stock options.  Capitalized
terms not defined in the text are defined in Section 19.

                2.       SHARES SUBJECT TO THE PLAN.

                         2.1 Number of Shares Available. Subject to Sections 2.2
and 14, the total number of Shares reserved and available for grant and issuance
pursuant  to Awards  under  the Plan  shall be  Thirteen  Million  Five  Hundred
Thousand  (13,500,000)  Shares.  Shares  issuable upon exercise of stock options
granted pursuant to the Company's 1985 Incentive and  Nonqualified  Stock Option
Plan (the  "Prior  Plan")  that  expire or become  unexercisable  for any reason
without having been exercised in full, shall no longer be available for exercise
under the Prior Plan,  but shall be available for  distribution  under this Plan
(not to exceed Ten Million (10,000,000) Shares). Subject to Sections 2.2 and 14,
Shares shall again be available for grant and issuance in connection with future
Awards under the Plan if such Shares cease to be subject to an Award.

                         2.2 Adjustment of Shares.  In the event that the number
of outstanding  Shares is changed by a stock dividend,  recapitalization,  stock
split,  reverse  stock  split,  subdivision,  combination,  reclassification  or
similar change in the capital structure of the Company without consideration, or
by a Corporate Transaction (as defined in Section 14.1) then, unless such change
results  in the  termination  of  all  outstanding  Awards  as a  result  of the
Corporate Transaction,  (a) the number of Shares reserved for issuance under the
Plan and (b) the Exercise  Prices of and number of Shares subject to outstanding
Awards shall be  proportionately  c adjusted,  subject to any required action by
the Board or the  stockholders  of the Company and  compliance  with  applicable
securities  laws;  provided,  however,  that  fractions  of a Share shall not be
issued but shall either be paid in cash at Fair Market Value or shall be rounded
up to the nearest Share, as determined by the Committee; and provided,  further,
that the Exercise Price of any Award may not be decreased to below the par value
of the Shares.

<PAGE>

                3.  ELIGIBILITY.  ISOs (as  defined  in  Section 5 below) may be
granted  only to  employees  (including  officers  and  directors  who are  also
employees) of the Company or of a Parent or Subsidiary of the Company. NQSOs (as
defined in Section 5 below) may be granted to  employees,  officers,  directors,
consultants,  independent contractors and advisors of the Company or any Parent,
Subsidiary or Affiliate of the Company;  provided such consultants,  contractors
and advisors render bona fide services not in connection with the offer and sale
of securities  in a  capital-raising  transaction.  A person may be granted more
than one Award  under the Plan.  Each  person is  eligible  to  receive up to an
aggregate maximum of One Million (1,000,000) Shares per fiscal year.

                4.       ADMINISTRATION.

                         4.1 Committee Authority. The Plan shall be administered
by the Committee.  Subject to the general purposes,  terms and conditions of the
Plan,  the Committee  shall have full power to implement and carry out the Plan.
The Committee shall have the authority to:

                (a)      construe  and  interpret  the Plan,  any  Stock  Option
                         Agreement and any other agreement or document  executed
                         pursuant to the Plan;

                (b)      prescribe,  amend and  rescind  rules  and  regulations
                         relating to the Plan;

                (c)      select persons to receive Awards;

                (d)      determine the form and terms of Awards;

                (e)      determine the number of Shares subject to Awards;

                (f)      determine whether Awards will be granted in replacement
                         of, or as alternatives  to, other Awards under the Plan
                         or any  other  incentive  or  compensation  plan of the
                         Company or any Parent,  Subsidiary  or Affiliate of the
                         Company;

                (g)      grant waivers of Plan or Award conditions;

                (h)      determine the vesting and exercisability of Awards;

                (i)      correct any defect,  supply any omission,  or reconcile
                         any  inconsistency  in the Plan, any Award or any Stock
                         Option Agreement;

                (j)      determine the  disposition  of Awards in the event of a
                         Participant's divorce or dissolution of marriage; and

                (k)      make all other  determinations  necessary  or advisable
                         for the administration of the Plan.

<PAGE>

                         4.2 Committee Discretion. Any determination made by the
Committee with respect to any Award shall be made in its sole  discretion at the
time of grant of the Award or,  unless in  contravention  of any express term of
the Plan or Award, at any later time, and such determination  shall be final and
binding on the Company and all persons having an interest in any Award under the
Plan.  The  Committee  may  delegate to one or more  officers of the Company the
authority to grant an Award under the Plan to Participants  who are not Insiders
of the Company.

                         4.3 Exchange Act  Requirements.  If two or more members
of the Board are Outside Directors, the Committee shall be comprised of at least
two members of the Board,  all of whom are Outside  Directors and  Disinterested
Persons.   The  Company  will  take   appropriate   steps  to  comply  with  the
disinterested  director  requirements  of  Section  16(b) of the  Exchange  Act,
including  but not  limited  to,  the  appointment  by the Board of a  Committee
consisting of not less than two persons (who are members of the Board),  each of
whom is a  Disinterested  Person.  It is the intent of the Company that the Plan
and Awards hereunder  satisfy and be interpreted in a manner,  that, in the case
of  Participants   who  are  or  may  be  Insiders,   satisfies  the  applicable
requirements  of Rule  16b-3 (or its  successor)  of the  Exchange  Act.  If any
provision of the Plan or of any Award would  otherwise  conflict with the intent
expressed in this Section 4.3, that  provision to the extent  possible  shall be
interpreted and deemed amended so as to avoid such conflict.

                5. STOCK  OPTIONS.  The  Committee  may grant Awards to eligible
persons and shall determine whether such Awards shall be Incentive Stock Options
within the meaning of the Code ("ISOs") or Nonqualified Stock Options ("NQSOs"),
the number of Shares subject to the Award,  the Exercise Price of the Award, the
period  during  which  the  Award  may be  exercised,  and all  other  terms and
conditions of the Award, subject to the following:

                         5.1 Form of Option Grant.  Each Award granted under the
Plan shall be  evidenced  by an Stock  Option  Agreement  which shall  expressly
identify  the  Award as an ISO or NQSO,  and be in such  form and  contain  such
provisions  (which need not be the same for each  Participant)  as the Committee
shall from time to time  approve,  and which shall comply with and be subject to
the terms and conditions of the Plan.

                         5.2 Date of Grant.  The date of grant of an Award shall
be the date on which the Committee makes the  determination to grant such Award,
unless  otherwise  specified by the Committee.  The Stock Option Agreement and a
copy of the Plan will be delivered to the  Participant  within a reasonable time
after the granting of the Award.

                         5.3 Exercise Period. Awards shall be exercisable within
the times or upon the events  determined  by the  Committee  as set forth in the
Stock Option Agreement;  provided,  however,  that no Award shall be exercisable
after the  expiration of ten (10) years from the date the Award is granted;  and
provided  further that no ISO granted to a person who directly or by attribution
owns  more than ten  percent  (10%) of the total  combined  voting  power of all
classes of stock of the Company or any Parent or Subsidiary of the Company ("Ten
Percent 


                                      -3-
<PAGE>

Stockholder")  shall be exercisable  after the expiration of five (5) years from
the date the Award is granted.  The Committee  also may provide for the exercise
of Awards to become  exercisable at one time or from time to time,  periodically
or otherwise, in such number or percentage as the Committee determines.

                         5.4  Exercise  Price.   The  Exercise  Price  shall  be
determined by the Committee when the Award is granted and shall be not less than
100% of the Fair Market Value of the Shares on the date of grant; provided, that
the Exercise Price of any ISO granted to a Ten Percent  Stockholder shall not be
less  than  110% of the Fair  Market  Value of the  Shares on the date of grant.
Payment for the Shares purchased may be made in accordance with Section 6 of the
Plan.

                         5.5 Method of Exercise. Awards may be exercised only by
delivery  to  the  Company  of  a  written  exercise  agreement  (the  "Exercise
Agreement") in a form approved by the Committee  (which need not be the same for
each   Participant),   stating  the  number  of  Shares  being  purchased,   the
restrictions  imposed  on the  Shares,  if any,  and  such  representations  and
agreements regarding  Participant's  investment intent and access to information
and other  matters,  if any, as may be required or  desirable  by the Company to
comply with  applicable  securities  laws,  together with payment in full of the
Exercise Price for the number of Shares being purchased.

                         5.6 Termination.  Notwithstanding  the exercise periods
set forth in the Stock  Option  Agreement,  exercise of an Award shall always be
subject to the following:

                (a)      If the  Participant is Terminated for any reason except
                         death or Disability, then Participant may exercise such
                         Participant's  Awards  only  to the  extent  that  such
                         Awards would have been exercisable upon the Termination
                         Date  no  later  than   three  (3)  months   after  the
                         Termination  Date  (or  such  longer  time  period  not
                         exceeding  five  years  as  may  be  determined  by the
                         Committee),  but  in  any  event,  no  later  than  the
                         expiration date of the Awards.

                (b)      If the  Participant  is terminated  because of death or
                         Disability (or the Participant dies within three months
                         of such termination),  then Participant's  Awards would
                         have been exercisable by Participant on the Termination
                         Date  and  must  be   exercised  by   Participant   (or
                         Participant's   legal   representative   or  authorized
                         assignee)  no later than (i) twelve (12)  months  after
                         the Termination  Date in the case of disability or (ii)
                         eighteen (18) months after the Termination  Date in the
                         case of death (or such longer time period not exceeding
                         five years as may be determined by the Committee),  but
                         in any event no later than the  expiration  date of the
                         Awards.

                         5.7 Limitations on Exercise.  The Committee may specify
a reasonable  minimum  number of Shares that may be purchased on any exercise of
an Award;  provided that 

                                      -4-
<PAGE>


such minimum number will not prevent  Participant  from exercising the Award for
the full number of Shares for which it is then exercisable.

                         5.8  Limitations  on ISOs.  The  aggregate  Fair Market
Value  (determined as of the date of grant) of Shares with respect to which ISOs
are  exercisable  for the first time by a  Participant  during any calendar year
(under the Plan or under any other incentive stock option plan of the Company or
any Affiliate,  Parent or Subsidiary of the Company) shall not exceed  $100,000.
If the Fair  Market  Value of Shares on the date of grant with  respect to which
ISOs are  exercisable  for the first time by a  Participant  during any calendar
year  exceeds  $100,000,  the Awards for the first  $100,000  worth of Shares to
become  exercisable  in such  calendar year shall be ISOs and the Awards for the
amount in excess of $100,000 that become exercisable in that calendar year shall
be NQSOs. In the event that the Code or the regulations  promulgated  thereunder
are  amended  after the  Effective  Date of the Plan to provide  for a different
limit on the Fair Market Value of Shares  permitted to be subject to ISOs,  such
different limit shall be  automatically  incorporated  herein and shall apply to
any Awards granted after the effective date of such amendment.

                         5.9 Modification,  Extension or Renewal.  The Committee
may modify,  extend or renew  outstanding  Awards and authorize the grant of new
Awards in substitution therefor;  provided that any such action may not, without
the written consent of Participant, impair any of Participant's rights under any
Award  previously  granted.  Any  outstanding  ISO that is  modified,  extended,
renewed or otherwise  altered shall be treated in accordance with Section 424(h)
of the Code. The Committee may reduce the Exercise  Price of outstanding  Awards
without  the  consent  of  Participants  affected  by a written  notice to them;
provided,  however, that the Exercise Price may not be reduced below the minimum
Exercise Price that would be permitted  under Section 5.4 of the Plan for Awards
granted  on the date the  action  is taken to reduce  the  Exercise  Price;  and
provided,  further,  that the Exercise  Price shall not be reduced below the par
value of the Shares, if any.

                         5.10 No  Disqualification.  Notwithstanding  any  other
provision  in  the  Plan,  no  term  of the  Plan  relating  to  ISOs  shall  be
interpreted,  amended or altered,  nor shall any discretion or authority granted
under the Plan be exercised,  so as to disqualify  the Plan under Section 422 of
the Code or, without the consent of the Participant  affected, to disqualify any
ISO under Section 422 of the Code.

                6.  PAYMENT FOR SHARE  PURCHASES.  Payment for Shares  purchased
pursuant to the Plan may be made in cash (by check) or, where expressly approved
for the Participant by the Committee and where permitted by law:

                (a)      by surrender of Shares that either: (1) have been owned
                         by  Participant  for more than six (6)  months and have
                         been paid for within the  meaning of SEC Rule 144 (and,
                         if such shares were  purchased  from the Company by use
                         of a  promissory  note,  such note has been  fully paid
                         with respect to such  Shares);  or (2) were obtained by
                         Participant in the public market;


                                      -5-
<PAGE>

                (b)      by waiver of compensation due or accrued to Participant
                         for services rendered;

                (c)      provided  that  a public market for the Company's stock
                         exists:

                         (1)      through  a "same  day  sale"  commitment  from
                                  Participant  and  a  broker-dealer  that  is a
                                  member   of  the   National   Association   of
                                  Securities  Dealers (a "NASD Dealer")  whereby
                                  the Participant irrevocably elects to exercise
                                  the Award and to sell a portion  of the Shares
                                  so  purchased in order to pay for the Exercise
                                  Price, and whereby the NASD Dealer irrevocably
                                  commits upon receipt of such Shares to forward
                                  the Exercise Price directly to the Company; or

                         (2)      through a "margin" commitment from Participant
                                  and  a   NASD   Dealer   whereby   Participant
                                  irrevocably  elects to exercise  the Award and
                                  to pledge the Shares so  purchased to the NASD
                                  Dealer in a margin  account as security  for a
                                  loan from the NASD Dealer in the amount of the
                                  Exercise  Price,  and  whereby the NASD Dealer
                                  irrevocably   commits  upon  receipt  of  such
                                  Shares to forward the exercise  price directly
                                  to the Company; or

                (d)      by any combination of the foregoing.

                7.       WITHHOLDING TAXES.

                         7.1  Withholding  Generally.  Whenever Shares are to be
issued in satisfaction of Awards granted under the Plan, the Company may require
the Participant to remit to the Company an amount sufficient to satisfy federal,
state  and local  withholding  tax  requirements  prior to the  delivery  of any
certificate or certificates for such Shares.  Whenever, under the Plan, payments
in  satisfaction  of Awards are to be made in cash, such payment shall be net of
an amount  sufficient  to satisfy  federal,  state,  and local  withholding  tax
requirements.

                         7.2 Stock Withholding. When, under applicable tax laws,
a Participant  incurs tax liability in connection with the exercise of any Award
that is subject to tax  withholding  and the Participant is obligated to pay the
Company  the  amount  required  to be  withheld,  the  Committee  may  allow the
Participant  to satisfy the minimum  withholding  tax  obligation by electing to
have the  Company  withhold  from the Shares to be issued  that number of Shares
having a Fair Market Value equal to the minimum amount  required to be withheld,
determined on the date that the amount of tax to be withheld is to be determined
(the "Tax Date").  All  elections by a Participant  to have Shares  withheld for
this purpose shall be made in writing in a form  acceptable to the Committee and
shall be subject to the following restrictions:

                (a)      the election must be made on or prior to the applicable
                         Tax Date;

                                      -6-

<PAGE>

                (b)      once made, then except as provided below,  the election
                         shall be irrevocable as to the particular  Shares as to
                         which the election is made;

                (c)      all  elections  shall  be  subject  to the  consent  or
                         disapproval of the Committee;

                (d)      if the  Participant is an Insider and if the Company is
                         subject to Section  16(b) of the Exchange  Act: (1) the
                         election  may not be made  within six (6) months of the
                         date  of  grant  of  the  Award,  except  as  otherwise
                         permitted by SEC Rule 16b-3(e)  under the Exchange Act,
                         and  (2)   either  (A)  the   election   to  use  stock
                         withholding  must be irrevocably  made at least six (6)
                         months prior to the Tax Date  (although  such  election
                         may be  revoked  at any  time at least  six (6)  months
                         prior to the Tax Date) or (B) the exercise of the Award
                         or  election to use stock  withholding  must be made in
                         the ten (10) day  period  beginning  on the  third  day
                         following  the release of the  Company's  quarterly  or
                         annual summary statement of sales or earnings; and

                (e)      in the event  that the Tax Date is  deferred  until six
                         (6) months after the  delivery of Shares under  Section
                         83(b) of the Code,  the  Participant  shall receive the
                         full  number  of  Shares  with  respect  to  which  the
                         exercise  occurs,   but  such   Participant   shall  be
                         unconditionally obligated to tender back to the Company
                         the proper number of Shares on the Tax Date.

                8.       PRIVILEGES OF STOCK OWNERSHIP.

                         8.1 Voting and Dividends. No Participant shall have any
of the rights of a  stockholder  with respect to any Shares until the Shares are
issued to the  Participant.  After  Shares  are issued to the  Participant,  the
Participant shall be a stockholder and have all the rights of a stockholder with
respect to such Shares, including the right to vote and receive all dividends or
other distributions made or paid with respect to such Shares.

                         8.2  Financial  Statements.  The Company  shall provide
financial statements to each Participant prior to such Participant's purchase of
Shares under the Plan, and to each  Participant  annually during the period such
Participant has Awards outstanding;  provided, however, the Company shall not be
required to provide such financial  statements to Participants whose services in
connection with the Company assure them access to equivalent information.

                9.  TRANSFERABILITY.  Subject to Section 4.1(j),  Awards granted
under the Plan,  and any interest  therein,  shall not: (a) be  transferable  or
assignable by the Participant,  (b) be made subject to execution,  attachment or
similar  process,  otherwise  than  by  will  or by  the  laws  of  descent  and
distribution or as consistent with the specific Plan and Stock Option  Agreement
provisions  relating thereto or (c) during the lifetime of the  Participant,  be
exercisable by anyone other than the Participant, and any elections with respect
to an Award, may be made only by the Participant.


                                      -7-
<PAGE>


                10.   CERTIFICATES.   All   certificates  for  Shares  or  other
securities  delivered  under the Plan shall be  subject  to such stock  transfer
orders,  legends and other  restrictions  as the Committee may deem necessary or
advisable, including restrictions under any applicable federal, state or foreign
securities law, or any rules,  regulations and other  requirements of the SEC or
any stock  exchange or automated  quotation  system upon which the Shares may be
listed.

                11.  SECURITIES LAW AND OTHER  REGULATORY  COMPLIANCE.  An Award
shall not be effective  unless such Award is in compliance  with all  applicable
federal and state  securities  laws,  rules and regulations of any  governmental
body, and the  requirements of any stock exchange or automated  quotation system
upon which the  Shares may then be listed,  as they are in effect on the date of
grant  of the  Award  and  also  on the  date of  exercise  or  other  issuance.
Notwithstanding  any other  provision  in the Plan,  the  Company  shall have no
obligation to issue or deliver  certificates  for Shares under the Plan prior to
(a)  obtaining  any  approvals  from  governmental  agencies  that  the  Company
determines are necessary or advisable, and/or (b) completion of any registration
or other  qualification  of such shares under any state or federal law or ruling
of any  governmental  body  that  the  Company  determines  to be  necessary  or
advisable.  The Company shall be under no obligation to register the Shares with
the SEC or to effect compliance with the registration,  qualification or listing
requirements of any state securities laws, stock exchange or automated quotation
system,  and the Company shall have no liability for any inability or failure to
do so.

                12. NO  OBLIGATION  TO EMPLOY.  Nothing in the Plan or any Award
granted  under the Plan shall  confer or be deemed to confer on any  Participant
any right to continue in the employ of, or to  continue  any other  relationship
with, the Company or any Parent, Subsidiary or Affiliate of the Company or limit
in any way the right of the Company or any Parent,  Subsidiary  or  Affiliate of
the Company to terminate  Participant's  employment or other relationship at any
time, with or without cause.

                13.  EXCHANGE AND BUYOUT OF AWARDS.  The  Committee  may, at any
time or from  time to time,  authorize  the  Company,  with the  consent  of the
respective  Participants,  to issue new Awards in exchange for the surrender and
cancellation of any or all outstanding Awards. The Committee may at any time buy
from a Participant an Award previously  granted with payment in cash,  Shares or
other consideration, based on such terms and conditions as the Committee and the
Participant shall agree.

                14.      CORPORATE TRANSACTIONS.

                         14.1  Corporate   Transactions.   In  the  event  of  a
Corporate  Transaction (as defined in this Section 14.1), the  exercisability of
each  Award  shall  be  automatically  accelerated  so that  each  Award  shall,
immediately before the specified  effective date for the Corporate  Transaction,
become fully  exercisable  with respect to the total number of Shares and may be
exercised for all or any portion of such Shares;  provided,  that an Award shall
not be accelerated  if and to the extent that such Award is, in connection  with
the Corporate Transaction,  either to be assumed by the successor corporation or
parent thereof or to be replaced with a 

                                      -9-
<PAGE>


comparable  option to  purchase  shares of the  capital  stock of the  successor
corporation or parent thereof.  The determination of comparability shall be made
by the Committee, and the Committee's  determination shall be final, binding and
conclusive.  Upon the consummation of a Corporate  Transaction,  all outstanding
Awards shall, to the extent not previously exercised or assumed by the successor
corporation or its parent, terminate and cease to be exercisable.

                                    "Corporate  Transaction"  means (a) a merger
or  acquisition  in which the Company is not the surviving  entity (except for a
transaction  the principal  purpose of which is to change the State in which the
Company is incorporated),  (b) the sale, transfer or other disposition of all or
substantially  all of the  assets  of the  Company  or (c) any  other  corporate
reorganization or business  combination that is not approved by the Board and in
which  the  beneficial  ownership  of 50% or more of the  Company's  outstanding
voting stock is transferred.

                         14.2 Change in Control.  Notwithstanding  any provision
in Section 14.1 to the contrary, in the event of a Change in Control (as defined
in this  Section  14.2),  each Award shall  automatically  accelerate  effective
fifteen (15) days following the effective date of the Change in Control, so that
each Award shall  become fully  exercisable  with respect to the total number of
Shares and may be exercised for all or any portion of such Shares. Upon a Change
in Control,  all outstanding  Awards  accelerated shall remain fully exercisable
until the  expiration or sooner  termination  of the Award term specified in the
Stock Option Agreement.

                                    A  "Change  in  Control"  shall be deemed to
occur:  (a) should a person or related group of persons,  other than the Company
or a person that directly or indirectly  controls,  is controlled by or is under
common  control  with the  Company,  becomes the  beneficial  owner  (within the
meaning of Rule 13d-3 of the General  Rules and  Regulations  under the Exchange
Act) of 25% or more of the  Company's  outstanding  voting  stock  pursuant to a
tender  or  exchange  offer  that  the  Board  does not  recommend  and that the
stockholders of the Company  accept;  or (b) on the first date within any period
of  twenty-four  (24)  consecutive  months or less on which  there is effected a
change in the  composition  of the Board by reason of a contested  election such
that a majority of the Board  members cease to be comprised of  individuals  who
either (i) have been members of the Board  continuously  since the  beginning of
such period or (ii) have been elected or nominated for election as Board members
during  such  period by at least a majority of the Board  members  described  in
clause (i) who were still in office at the time such election or nomination  was
approved by the Board.

                         14.3   Dissolution.   In  the  event  of  the  proposed
dissolution  or  liquidation  of  the  Company,   the  Board  shall  notify  the
Participant  at least  fifteen (15) days prior to such proposed  action.  To the
extent  that  Awards  have not  been  previously  exercised,  such  Awards  will
terminate immediately prior to the consummation of such proposed action.

                         14.4 Assumption of Awards by the Company.  The Company,
from time to time, also may substitute or assume  outstanding  awards granted by
another company, whether in connection with an acquisition of such other company
or otherwise,  by either (a) granting an Award under the Plan in substitution of
such other company's award, or (b) assuming such award as if it had been granted
under the Plan if the terms of such  assumed  award could be applied to an

                                      -9-
<PAGE>

Award  granted  under  the  Plan.  Such  substitution  or  assumption  shall  be
permissible  if the holder of the  substituted  or assumed award would have been
eligible to be granted an Award under the Plan if the other  company had applied
the rules of the Plan to such grant.  In the event the Company  assumes an award
granted by another company,  the terms and conditions of such award shall remain
unchanged  (except that the  exercise  price and the number and nature of Shares
issuable  upon  exercise  of any  such  option  will be  adjusted  appropriately
pursuant  to Section  424(a) of the Code).  In the event the  Company  elects to
grant a new Award rather than assuming an existing option, such new Award may be
granted with a similarly adjusted Exercise Price.

                15.  ADOPTION AND  STOCKHOLDER  APPROVAL.  The Plan shall become
effective  on the date that it is adopted by the Board (the  "Effective  Date").
The Plan shall be approved by the stockholders of the Company  (excluding Shares
issued pursuant to this Plan),  consistent with applicable  laws,  within twelve
months before or after the Effective  Date.  Upon the Effective  Date, the Board
may grant Awards pursuant to the Plan; provided, however, that: (a) no Award may
be exercised prior to initial stockholder  approval of the Plan and (b) no Award
granted  pursuant to an  increase in the number of Shares  approved by the Board
shall be  exercised  prior to the time such  increase  has been  approved by the
stockholders of the Company.  For so long as and whenever the Company is subject
to  Section  16(b)  of the  Exchange  Act,  the  Company  will  comply  with the
requirements  of Rule 16b-3 (or its  successor),  as  amended,  with  respect to
stockholder approval.

                16. TERM OF PLAN.  The Plan will  terminate  ten (10) years from
the Effective Date or, if earlier, the date of stockholder approval.

                17.  AMENDMENT OR TERMINATION OF PLAN. The Board may at any time
terminate  or  amend  the  Plan in any  respect,  including  without  limitation
amendment of any form of Stock Option  Agreement  or  instrument  to be executed
pursuant to the Plan; provided,  however,  that the Board shall not, without the
approval of the  stockholders of the Company,  amend the Plan in any manner that
requires  such  stockholder  approval  pursuant  to the Code or the  regulations
promulgated  thereunder as such provisions apply to ISO plans or pursuant to the
Exchange Act or Rule 16b-3 (or its successor), as amended, thereunder; provided,
further, that no amendment may be made to outstanding Awards without the consent
of the Participant.

                18. NONEXCLUSIVITY OF THE PLAN. Neither the adoption of the Plan
by the Board,  the submission of the Plan to the stockholders of the Company for
approval,  nor any  provision  of the Plan shall be  construed  as creating  any
limitations  on the power of the  Board to adopt  such  additional  compensation
arrangements  as it may  deem  desirable,  including,  without  limitation,  the
granting of stock options  otherwise than under the Plan, and such  arrangements
may be either generally applicable or applicable only in specific cases.

                19. DEFINITIONS.  As used in the Plan, the following terms shall
have the following meanings:

                         "Affiliate"  means any  corporation  that directly,  or
indirectly through one or more intermediaries,  controls or is controlled by, or

                        1984 EMPLOYEE STOCK PURCHASE PLAN

             (Amended and Restated Effective as of August 25, 1993)
                         (Amended as of April 29, 1997)





         Section 1.        Establishment of the Plan.

         The  Integrated  Device  Technology,   Inc.  qualified  Employee  Stock
Purchase  Plan (the  "Plan") is amended  and  restated  to  increase  the shares
available  for purchase  under the Plan and to comply with the  requirements  of
Section 16 of the Securities  Exchange Act of 1934.  The Plan provides  Eligible
Employees  with an  opportunity  to purchase the Company's  common stock so that
they may increase their proprietary  interest in the success of the Company. The
Plan, which provides for the purchase of stock through payroll  withholding,  is
intended to qualify under Section 423 of the Code.

         Section 2.        Definitions.

                  (a)  "Board  of  Directors"  or  "Board"  means  the  Board of
Directors of the Company.

                  (b)  "Code"  means  the  Internal  Revenue  Code of  1986,  as
amended.

                  (c) "Company"  means  Integrated  Device  Technology,  Inc., a
Delaware corporation.

                  (d)  "Compensation"  means  the  base  compensation  paid to a
Participant during a Participation  Period in cash or in kind including overtime
and shift differential.  Incentive  compensation,  commissions and other bonuses
and other forms of  compensation  for work outside the regular work schedule are
excluded.

                  (e)  "Date  of  Participation"   means  the  first  day  of  a
Participation Period.

                  (f) "Eligible  Employee" means any Employee of a Participating
Company (i) who has been continuously  employed by the Participating Company for
at least three (3) months prior to the  commencement of a Participation  Period,
(ii) who is customarily employed for more than twenty (20) hours per week, (iii)
who is customarily employed for more than five (5) months per calendar year, and
(iv) who is an Employee at the  Commencement  of a Participation  Period.  If an
Employee has been  employed less than three months and is granted a formal leave
of absence,  service,  prior to and after the leave, will count toward the three
months waiting period for  eligibility.  Rehired  Employees with less than a six
month break in service  will  receive  



<PAGE>


full  credit  for past  service to  determine  eligibility;  otherwise,  rehired
Employees will be treated as new Employees for purposes of eligibility.

                  In the  event an  Eligible  Employee  fails to  remain  in the
continuous  employ of a  Participating  Company  customarily for at least twenty
(20) hours per week  during a  Participation  Period,  he will be deemed to have
elected to  withdraw  from the Plan and the payroll  deductions  credited to his
account  will be returned to him;  provided  that a  Participant  who goes on an
unpaid leave of absence shall be permitted to remain in the Plan with respect to
a Participation  Period which commenced prior to such leave of absence.  If such
Participant is not guaranteed  reemployment by contract or statute and the leave
of absence extends beyond ninety (90) days, such Participant  shall be deemed to
have  terminated  employment  on the  ninety-first  (91st)  day of such leave of
absence. Payroll deductions for a Participant who has been on an unpaid leave of
absence  will  resume  at the same rate as in effect  prior to such  leave  upon
return to work unless changed by such  Participant or unless the Participant has
been on an unpaid leave of absence  either  throughout  an entire  Participation
Period  or for more than 90 days,  in which  case the  Participant  shall not be
permitted  to re-enter  the Plan until a  participation  agreement is filed with
respect  to  a  subsequent  Participation  Period  which  commences  after  such
Participant has returned to work from the unpaid leave of absence.

                  (g)   "Employee"   means   any   common-law   employee   of  a

quoted by the National  Association of Securities  Dealers,  Inc. ("Nasdaq") for
such date; (ii) if the Stock is traded  over-the-counter on the date in question
and was classified as a national market issue,  then the Fair Market Value shall
be equal to the  last-transaction  price  quoted by the  Nasdaq  system for such
date;  (iii) if the  Stock  is  traded  on a  national  exchange  on the date in
question,  then the Fair Market  Value  shall be the  highest  closing bid price
reported on such  exchange for such date. If the Stock is not traded on the date
as of which the Fair Market Value is to be  determined,  Fair Market Value shall
be determined as of the first  preceding date on which Stock was traded.  In all
cases the  determination of Fair Market Value by the Board of Directors shall be
conclusive and binding on all persons.

                  (i)  "Participant"  means an Eligible  Employee  who elects to
participate in the Plan, as provided in Section 5 hereof.

                  (j) "Participating Company" means the Company and such present
or future  Subsidiaries of the Company as the Board of Directors shall from time
to time designate.

                  (k)  "Participation   Period"  means  a  period  during  which

                  (n)  "Stock"  means the common  stock,  no par  value,  of the
Company.

                  (o) "Subsidiary" means a subsidiary  corporation as defined in

         Section 3.        Duration; Shares Authorized.

         The Plan shall  terminate  on the last day of the  Company's  2008-2009
fiscal year,  unless terminated  earlier by the Board of Directors.  The maximum
aggregate  number  of  shares  which  may be  offered  under  the Plan  shall be
5,050,000  shares of Stock,  subject to  adjustment  as  provided  in Section 13
hereof.

         Section 4.        Administration.

                  (a) The Plan  shall be  administered  by a Plan  Administrator
appointed by the Board of Directors.  The interpretation and construction by the
Plan  Administrator  of any  provision  of the Plan or of any right to  purchase
stock qualified hereunder shall be conclusive and binding on all persons.

                  (b) No member of the Board or the Plan Administrator  shall be
liable for any action or  determination  made in good faith with  respect to the
Plan or the right to purchase Stock hereunder.  The Plan Administrator  shall be
indemnified by the Company against the reasonable expenses, including attorney's
fees actually and  necessarily  incurred in  connection  with the defense of any
action,  suit or proceeding,  or in connection with any appeal therein, to which
it may be a party by reason of any  action  taken or  failure to act under or in
connection  with the Plan or any stock  purchased  thereunder,  and  against all
amounts paid by it in settlement  thereof  (provided such settlement is approved
by  independent  legal  counsel  selected  by  the  Company)  or  paid  by it in
satisfaction  of a judgment in any such action,  suit or  proceeding,  except in
relation  to matters as to which it shall be adjudged  in such  action,  suit or
proceeding that the Plan Administrator is liable for negligence or misconduct in
the  performance  of its  duties;  provided  that  within  sixty (60) days after
institution of any such action, suit or proceeding, the Plan Administrator shall
in writing offer the Company the opportunity,  at its own expense, to handle and
defend the same.

                  (c) All costs and expenses  incurred in administering the Plan
shall be paid by the Company.  The Board or the Plan  Administrator  may request
advice for  assistance  or employ such other persons as are necessary for proper
administration of the Plan.

         Section 5.        Eligibility and Participation.

                  (a) Any person who  qualifies  or will  qualify as an Eligible
Employee on the Date of Participation with respect to a Participation Period may
elect to  participate  in the Plan for such  Participation  Period.  An Eligible
Employee may elect to  participate  by  executing  the  participation  agreement
prescribed  for  such  purpose  by the  Plan  Administrator.  The  participation

                                       3

<PAGE>


agreement shall be filed with the Plan  Administrator no later than the deadline
stated on the participation agreement, and if none is stated, then no later than
the first day of the Participation Period. The Eligible Employee shall designate
on the participation  agreement the percentage of his or her Compensation  which
he or she elects to have  withheld for the  purchase of Stock,  which may be any
whole percentage from 2 to 10% of the Participant's Compensation.

                  (b) By enrolling in the Plan, a Participant shall be deemed to
have elected to purchase  the maximum  number of whole shares of Stock which can
be purchased with the amount of the Participant's Compensation which is withheld
during the  Participation  Period.  However,  with respect to any  Participation
Period, no Participant shall be eligible to purchase more than two thousand five
hundred  (2,500) shares of Stock  (appropriately  adjusted if the  Participation
Period is longer than a fiscal quarter and for events  described in Section 13),
provided  that such  amount  shall not  result in the  limitations  set forth in
Section 14 being exceeded.

                  (c) Once enrolled,  a Participant will continue to participate
in the Plan for each succeeding  Participation Period until he or she terminates
participation  or ceases to qualify as an Eligible  Employee.  A Participant who
withdraws  from  the Plan in  accordance  with  Section  10 may  again  become a
Participant,  if he or she  then  is an  Eligible  Employee,  by  following  the
procedure described in Section 5(a).

         Section 6.        Participation Periods.

         The Plan shall be implemented by one or more  Participation  Periods of
not more than  twenty-seven  (27) months  each.  (The  current  duration of each
Participation  Period  is  each  of  the  Company's  fiscal  quarters,  and  the
Participation Periods commence on the first day of each such quarter.) The Board
of Directors  may determine  the duration of each  Participation  Period and the
commencement  dates,   provided  that  no  Participation  Period  shall  have  a
commencement date after January 1, 2009.

         Section 7.        Purchase Price.

         The  Purchase  Price for each share of Stock shall be the lesser of (i)
eighty-five  percent (85%) of the Fair Market Value of such share on the Date of
Participation or (ii) eighty-five percent (85%) of the Fair Market Value of such
share on the last trading day during the Participation Period.

         Section 8.        Employee Contributions.

         A Participant  may purchase  shares of Stock solely by means of payroll
deductions.  Payroll  deductions,  as designated by the Participant  pursuant to
Section  5(a),  shall  commence  with  the  first  paycheck  issued  during  the
Participation  Period  and  shall be  deducted  from  each  subsequent  paycheck
throughout the Participation  Period.  If a Participant  desires to decrease the
rate of payroll  withholding  during the Participation  Period, he or she may do
so, if  permitted  by the Plan  Administrator,  one time during a  Participation
Period by filing a new participation agreement with the Plan Administrator. Such
decrease  will be  effective  as of the first day of the second  payroll  period
which begins  following  the receipt of the new  participation  agreement.  If

                                       4
<PAGE>

a Participant  desires to increase or decrease the rate of payroll  withholding,
he or she may do so effective for the next Participation  Period by filing a new
participation  agreement  with  the Plan  Administrator  on or  before  the date
specified by the Plan  Administrator,  and if none is stated, then no later than
the  first  day of the  Participation  Period  for  which  such  change is to be
effective.

         Section 9.        Plan Accounts; Purchase of Shares.

                  (a) The Company  will  maintain a Plan Account on its books in
the  name of each  Participant.  At the  close of each pay  period,  the  amount
deducted  from  the   Participant's   Compensation   will  be  credited  to  the
Participant's Plan Account.

                  (b) As of the  last  day of  each  Participation  Period,  the
amount then in the  Participant's  Plan  Account will be divided by the Purchase
Price,  and the number of whole shares which results (subject to the limitations
described in Section 5(b), 9(c) and 14) shall be purchased from the Company with
the funds in the Participant's Plan Account. Share certificates representing the
number of shares of Stock so purchased shall be delivered to a brokerage account
designated  by the Plan  Administrator  and kept in such  account  pursuant to a
participation  agreement  (which shall be uniform)  between each Participant and
the Company and subject to the conditions described therein.

                  (c) In the event that the aggregate number of shares which all
Participants  elect to purchase during a  Participation  Period shall exceed the
number of shares  remaining  available  for  issuance  under the Plan,  then the
number  of shares to which  each  Participant  shall  become  entitled  shall be
determined  by  multiplying  the number of shares  available  for  issuance by a
fraction  the  numerator  of  which  is the  sum of the  number  of  shares  the
Participant  has elected to purchase  pursuant to Section 5, and the denominator
of which is the sum of the number of shares which all employees  have elected to
purchase  pursuant to Section 5. Any cash amount remaining in the  Participant's
Plan Account under these circumstances shall be refunded to the Participant.

                  (d) Any amount  remaining  in the  Participant's  Plan Account
caused by a surplus due to fractional  shares after  deducting the amount of the
Purchase Price for the number of whole shares issued to the Participant shall be
carried over in the Participant's Plan Account for the succeeding  Participation
Period, without interest. Any amount remaining in the Participant's Plan Account
caused by  anything  other  than a surplus  due to  fractional  shares  shall be
refunded to the Participant in cash, without interest.

                  (e)  As  soon  as  practicable   following  the  end  of  each
Participation  Period,  the Company  shall  deliver to each  Participant  a Plan
Account statement setting forth the amount of payroll  deductions,  the purchase
price, the number of shares purchased and the remaining cash balance, if any.

         Section 10.       Withdrawal From the Plan.

         A Participant may elect to withdraw from  participation  under the Plan
at any  time  up to the  last  day  of a  Participation  Period  by  filing  the
prescribed  form with the Plan  Administrator. 

                                       5

<PAGE>


As soon as practicable  after a withdrawal,  payroll  deductions shall cease and
all amounts credited to the Participant's Plan Account will be refunded in cash,
without  interest.  A Participant who has withdrawn from the Plan shall not be a
Participant in future Participation  Periods,  unless he or she again enrolls in
accordance with the provisions of Section 5.

         Section 11.       Effect of Termination of Employment or Death.

                  (a) Termination of employment as an Eligible  Employee for any
reason,  including death,  shall be treated as an automatic  withdrawal from the
Plan under  Section  10. A transfer  from one  Participating  Company to another
shall not be treated as a termination of employment.

                  (b)  A  Participant  may  file  a  written  designation  of  a
beneficiary   who  is  to  receive  any  shares  and  cash,  if  any,  from  the
Participant's  Account under the Plan in the event of such  Participant's  death
subsequent to the purchase of shares but prior to delivery to him of such shares
and  cash.  In  addition,  a  Participant  may file a written  designation  of a
beneficiary who is to receive any cash from the Participant's  Account under the
Plan in the  event  of such  Participant's  death  prior  to the  last  day of a
Participation Period.

                  (c) Such  designation  of  beneficiary  may be  changed by the
Participant  at any time by  written  notice.  In the  event  of the  death of a
Participant in the absence of a valid designation of a beneficiary who is living
at the time of such  Participant's  death, the Company shall deliver such shares
and/or cash in accordance with the  Participant's  designation of  beneficiaries
under the Integrated  Device  Technology,  Inc. Long Term Incentive Plan; or, in
the absence of such designation,  to the executor or administrator of the estate
of the Participant;  or if no such executor or administrator  has been appointed
(to the knowledge of the Company),  the Company, in its discretion,  may deliver
such  shares  and/or  cash to the  spouse  or to any one or more  dependents  or
relatives of the Participant; or if no spouse, dependent or relative is known to
the Company, then to such other person as the Company may designate.

         Section 12.       Rights Not Transferable.

         The rights or interests of any Participant in the Plan, or in any Stock
or  moneys  to which he or she may be  entitled  under  the  Plan,  shall not be
transferable  by voluntary or involuntary  assignment or by operation of law, or
by any other  manner  other than as permitted by the Code or by will or the laws
of  descent  and  distribution.  If a  Participant  in any  manner  attempts  to
transfer,  assign or otherwise  encumber his or her rights or interest under the
Plan,  other than as permitted by the Code or by will or the laws of descent and
distribution, such act shall be treated as an automatic withdrawal under Section
10.

         Section 13.       Recapitalization, Etc.

                  (a) The aggregate  number of shares of Stock offered under the
Plan,  the  number  and price of shares  which any  Participant  has  elected to
purchase  pursuant  to  Section  5 and the  maximum  number  of  shares  which a
Participant  may elect to purchase  under the Plan in any  Participation  Period
shall be proportionately  adjusted for any increase or decrease in the number of
issued shares of Stock resulting from a subdivision or  consolidation  of shares
or any 

                                       6

other capital adjustment,  the payment of a stock dividend, or other increase or
decrease  in such  shares  effected  without  receipt  of  consideration  by the
Company.

                  (b)  In the  event  of a  dissolution  or  liquidation  of the
Company,  or a merger or  consolidation  to which the  Company is a  constituent
corporation, this Plan shall terminate, unless the plan of merger, consolidation
or reorganization provides otherwise, and all amounts which each Participant has
paid towards the Purchase Price of Stock  hereunder  shall be refunded,  without
interest.

                  (c) The Plan shall in no event be construed to restrict in any
way the  Company's  right  to  undertake  a  dissolution,  liquidation,  merger,
consolidation or other reorganization.

         Section 14.       Limitation on Stock Ownership.

         Notwithstanding  any provision  herein to the contrary,  no Participant
shall be permitted to elect to participate in the Plan (i) if such  Participant,
immediately after his or her election to participate, would own stock possessing
five  percent  (5%) or more of the total  combined  voting power or value of all
classes of stock of the Company or any parent or Subsidiary  of the Company,  or
(ii) if under the terms of the Plan the rights of the Employee to purchase Stock
under this Plan and all other  qualified  employee  stock  purchase plans of the
Company or its  Subsidiaries  would accrue at a rate which  exceeds  twenty-five
thousand dollars ($25,000) of the Fair Market Value of such Stock (determined at
the time such right is granted) for each  calendar  year for which such right is
outstanding  at any time.  For purposes of this  Section 14,  ownership of stock
shall be determined by the attribution  rules of Section 425(d) of the Code, and
Participants  shall be  considered  to own any stock  which they have a right to
purchase under this or any other stock plan.

         Section 15.       No Rights as an Employee.

         Nothing in the Plan shall be  construed to give any person the right to
remain in the employ of a  Participating  Company.  Each  Participating  Company
reserves the right to terminate the employment of any person at any time and for
any reason.

         Section 16.       Rights as a Stockholder.

         A Participant shall have no rights as a stockholder with respect to any
shares he or she may have a right to  purchase  under the Plan until the date of
issuance of a stock certificate to the brokerage account  designated by the Plan
Administrator for shares of Stock issued pursuant to the Plan.

         Section 17.       Use of Funds.

         All payroll  deductions  received or held by the Company under the Plan
may be used by the Company for any corporate purpose,  and the Company shall not
be obligated to segregate such payroll deductions in separate accounts.

         Section 18.       Amendment or Termination of the Plan.

         The  Board of  Directors  shall  have the  right to  amend,  modify  or
terminate the Plan at any time without notice. An amendment of the Plan shall be
subject to shareholder  approval only to the extent required by applicable laws,
regulations or rules.

         Section 19.       Governing Law.

         The Plan  shall be  governed  by,  and  construed  and  interpreted  in
accordance with, the laws of the State of Delaware.
