                       REGISTRATION STATEMENT ON FORM S-8

                                     PART II

                 INFORMATION REQUIRED IN REGISTRATION STATEMENT

Item  3.  Incorporation of Documents by Reference.

 The following  documents and information  previously  filed with the Securities
and Exchange  Commission (the  "Commission")  by Micro Linear  Corporation  (the
"Company") are hereby incorporated by reference in this Registration Statement:

 (a) The Company's Annual Report on Form 10-K for the fiscal year ended December
31, 1997 filed pursuant to Section 13(a) or 15(d) of the Securities Exchange Act
of 1934, as amended (the "Exchange Act").

 (b) The Company's Quarterly Report on Form 10-Q for the quarter ended March 31,
1998 filed pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of
1934, as amended (the "Exchange Act").

 (c) The  description  of the  Company's  common stock which is contained in the
Company's  Registration Statement on Form 8-A filed with the Commission pursuant
to Section 12 of the Securities  Exchange Act of 1934, as amended (the "Exchange
Act"),  and  any  description  of any  securities  of the  Registrant  which  is
contained  in any  registration  statement  filed  after the date  hereof  under
Section 12 of the Exchange Act,  including any amendment or report filed for the
purpose of updating any such description.

 All documents  subsequently  filed by the Company  pursuant to Sections  13(a),
13(c), 14 and 15(d) of the Exchange Act, prior to the filing of a post-effective
amendment which indicates that all securities registered have been sold or which
deregisters  all  securities  then  remaining  unsold,  shall  be  deemed  to be
incorporated by reference in this  Registration  Statement and to be part hereof
from the date of filing of such documents.

Item 4.   Description of Securities.

 Not applicable.

Item 5.   Interests of Named Experts and Counsel.

 Not applicable.

Item 6.  Indemnification of Directors and Officers.

 The Company's Certificate of Incorporation limits the liability of directors to
the maximum  extent  permitted  by Delaware  law.  Delaware  law  provides  that
directors of a company will not be  personally  liable for monetary  damages for
breach of their fiduciary duties as directors,  except for liability (i) for any
breach of their  duty of loyalty to the  company or its  stockholders,  (ii) for
acts or omissions not in good faith or which involve  intentional  misconduct or
knowing  violation of law, (iii) for unlawful  payments or dividends or unlawful
stock  repurchases or redemptions  as provided  Section 174 of Delaware  General
Corporation  Law or (iv) for  transactions  from which the  director  derived an
improper personal benefit.

 The Company's  Bylaws provide that the Company shall indemnify its officers and
directors and may indemnify its employees and other agents to the fullest extent
provided by Delaware law, including those  circumstances  where  indemnification
would otherwise be  discretionary  under Delaware law. The Company believes that
indemnification  under  its  Bylaws  covers at least  negligence  on the part of
indemnified parties. The Bylaws authorize the use of indemnification  agreements
and the Company has entered into such  agreements with each of its directors and
officers.

 The Company  carries officer and director  liability  insurance with respect to
certain matters, including matters arising under the Securities Act.

 Delaware Law does not permit a  corporation  to eliminate a director's  duty of
care, and the provisions of the Company's  Certificate of Incorporation  have no
effect  on  the  availability  of  equitable  remedies  such  as  injunction  or
rescission,  based  upon a  director's  breach of the duty of care.  Insofar  as
indemnification  for liabilities arising under the Exchange Act may be permitted
to foregoing  provisions and  agreements,  the Company has been informed that in
the  opinion  of the staff of the  Commission  such  indemnification  is against
public policy as expressed in the Exchange Act and is therefore unenforceable.

Item 7.   Exemption from Registration Claimed.

 Not applicable.

 23.3     Consent of Counsel (contained in Exhibit 5.1).

 24.1     Power of Attorney (see page II-4).

Item 9.  Undertakings.

 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 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.

 (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.

 (4)  The  undersigned  Registrant  hereby  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.

 (5) 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 Exchange 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  Exchange  Act and will be  governed  by the final
adjudication of such issue.

exercised in full, or is surrendered pursuant to an Option Exchange Program, the
unpurchased  Shares which were subject thereto shall become available for future
grant or sale under the Plan (unless the Plan has terminated).

        4. Administration of the Plan.

               (a)  Administration.  The Plan shall be  administered  by (i) the
Board or (ii) a  Committee,  which  committee  shall be  constituted  to satisfy
Applicable Laws.

               (b) Powers of the Administrator. Subject to the provisions of the
Plan, and in the case of a Committee,  subject to the specific duties  delegated
by the Board to such Committee,  the Administrator shall have the authority,  in
its discretion:

                       (i)  to determine the Fair Market Value of the Common
                            Stock;

                       (ii) to select the Service  Providers to whom Options may
be granted hereunder;

                       (iii) to determine whether and to what extent Options are
granted hereunder;

                       (iv) to determine the number of shares of Common Stock to
be covered by each Option granted
hereunder;

                       (v) to approve forms of agreement for use under the Plan;

                       (vi)  to  determine   the  terms  and   conditions,   not
inconsistent with the terms of the Plan, of any
award granted hereunder.  Such terms and conditions include, but are not limited
to, the exercise price,  the time or times when Options may be exercised  (which
may be based on performance  criteria),  any vesting  acceleration  or waiver of
forfeiture restrictions,  and any restriction or limitation regarding any Option
or the  shares  of Common  Stock  relating  thereto,  based in each case on such
factors as the Administrator, in its sole discretion, shall determine;
                       (vii) to reduce the  exercise  price of any Option to the
then current Fair Market Value if the
Fair Market Value of the Common Stock covered by such Option shall have declined
since the date the Option was granted;

                       (viii) to institute an Option Exchange Program;

                       (ix) to construe and  interpret the terms of the Plan and
awards granted pursuant to the Plan;

                       (x) to prescribe, amend and rescind rules and regulations
     relating to the Plan, including rules and regulations relating to sub-plans
established  for the purpose of qualifying  for  preferred  tax treatment  under
foreign tax laws;

                       (xi) to modify or amend each  Option  (subject to Section
     14(b) of the Plan),  including  the  discretionary  authority to extend the
post-termination  exercisability  period of  Options  longer  than is  otherwise
provided for in the Plan;

                       (xii) to authorize any person to execute on behalf of the
     Company any instrument required to effect the grant of an Option previously
granted by the Administrator;
                       (xiii) to determine the terms and restrictions applicable
to Options;

                       (xiv) to  allow  Optionees  to  satisfy  withholding  tax
     obligations by electing to have the Company  withhold from the Shares to be
issued upon  exercise  of an Option  that number of Shares  having a Fair Market
Value equal to the amount required to be withheld.  The Fair Market Value of the
Shares to be withheld  shall be determined on the date that the amount of tax to
be withheld is to be  determined.  All  elections  by an Optionee to have Shares
withheld for this purpose  shall be made in such form and under such  conditions
as the Administrator may deem necessary or advisable; and

                       (xv) to make all other determinations deemed necessary or
advisable for administering the Plan.

               (c)  Effect  of  Administrator's  Decision.  The  Administrator's
decisions,  determinations and interpretations shall be final and binding on all
Optionees and any other holders of Options.

        5. Eligibility.  Options may be granted to Service Providers;  provided,
however, that notwithstanding anything to the contrary contained in the Plan, an
Option may only be granted to an Officer as an  inducement  essential  to his or
her initial employment with the Company.

        6.  Limitation.  Neither  the Plan nor any Option  shall  confer upon an
Optionee any right with respect to continuing the Optionee's  relationship  as a
Service Provider with the Company,  nor shall they interfere in any way with the
Optionee's  right or the Company's  right to terminate such  relationship at any
time, with or without cause.

        7. Term of Plan.  The Plan shall become  effective  upon its adoption by
the  Board.  It shall  continue  in effect  for ten (10)  years,  unless  sooner
terminated under Section 14 of the Plan.

        8. Term of Option. The term of each Option shall be stated in the Option
Agreement.

        9.     Option Exercise Price and Consideration.

               (a)     Exercise  Price.  The per share exercise price for the 
Shares to be issued  pursuant to exercise of
an Option shall be determined by the Administrator.

               (b) Waiting Period and Exercise  Dates.  At the time an Option is
granted,  the Administrator  shall fix the period within which the Option may be
exercised and shall determine any conditions  which must be satisfied before the
Option may be exercised.

               (c) Form of Consideration.  The Administrator shall determine the
acceptable form of consideration for exercising an Option,  including the method
of payment. Such consideration may consist entirely of:

                       (i)    cash;

                       (ii)   check;

                       (iii)  promissory note;

                       (iv)  other  Shares  which  (A) in  the  case  of  Shares
     acquired  upon  exercise of an option,  have been owned by the Optionee for
more than six (6) months on the date of  surrender,  and (B) have a Fair  Market
Value on the date of  surrender  equal to the  aggregate  exercise  price of the
Shares as to which said Option shall be exercised;

                       (v)  consideration   received  by  the  Company  under  a
cashless exercise program implemented by the
Company in connection with the Plan;

                       (vi) a reduction  in the amount of any Company  liability
     to the Optionee,  including any liability  attributable  to the  Optionee's
participation  in  any   Company-sponsored   deferred  compensation  program  or
arrangement;
                       (vii) such other  consideration and method of payment for
the issuance of Shares to the extent
permitted by Applicable Laws; or

                       (viii)  any  combination  of  the  foregoing  methods  of
payment.

        10. Exercise of Option.

               (a) Procedure for Exercise;  Rights as a Shareholder.  Any Option
granted hereunder shall be exercisable according to the terms of the Plan and at
such times and under such conditions as determined by the  Administrator and set
forth in the Option Agreement.  An Option may not be exercised for a fraction of
a Share.

                       An Option shall be deemed exercised when the Company
     receives:  (i) written or electronic notice of exercise (in accordance with
the Option Agreement) from the person entitled to exercise the Option,  and (ii)
full payment for the Shares with respect to which the Option is exercised.  Full
payment may consist of any consideration and method of payment authorized by the
Administrator  and permitted by the Option Agreement and the Plan. Shares issued
upon  exercise of an Option  shall be issued in the name of the  Optionee or, if
requested  by the  Optionee,  in the name of the Optionee and his or her spouse.
Until the Shares are issued (as evidenced by the appropriate  entry on the books
of the Company or of a duly authorized transfer agent of the Company),  no right
to vote or receive  dividends or any other rights as a  shareholder  shall exist
with respect to the Optioned Stock,  notwithstanding the exercise of the Option.
The Company shall issue (or cause to be issued) such Shares  promptly  after the
Option is exercised.  No  adjustment  will be made for a dividend or other right
for which the record date is prior to the date the Shares are issued,  except as
provided in Section 12 of the Plan.

                       Exercising an Option in any manner shall decrease the 
     number of Shares  thereafter  available,  both for purposes of the Plan and
for sale  under the  Option,  by the  number of Shares as to which the Option is
exercised.
               (b)  Termination of  Relationship  as a Service  Provider.  If an
Optionee ceases to be a Service  Provider,  other than upon the Optionee's death
or Disability, the Optionee may exercise his or her Option, but only within such
period of time as is specified in the Option  Agreement,  and only to the extent
that the Option is vested on the date of termination (but in no event later than
the expiration of the term of such Option as set forth in the Option Agreement).
In the absence of a specified  time in the Option  Agreement,  the Option  shall
remain  exercisable for three (3) months  following the Optionee's  termination.
If, on the date of  termination,  the  Optionee  is not  vested as to his or her
entire Option,  the Shares  covered by the unvested  portion of the Option shall
revert to the Plan. If, after termination, the Optionee does not exercise his or
her Option  within the time  specified  by the  Administrator,  the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.

               (c) Disability of Optionee. If an Optionee ceases to be a Service
Provider as a result of the Optionee's Disability, the Optionee may exercise his
or her  Option  within  such  period  of  time  as is  specified  in the  Option
Agreement, to the extent the Option is vested on the date of termination (but in
no event  later than the  expiration  of the term of such Option as set forth in
the  Option  Agreement).  In the  absence  of a  specified  time  in the  Option
Agreement,  the Option shall remain exercisable for twelve (12) months following
the Optionee's termination.  If, on the date of termination, the Optionee is not
vested as to his or her  entire  Option,  the  Shares  covered  by the  unvested
portion of the Option  shall  revert to the Plan.  If,  after  termination,  the
Optionee does not exercise his or her Option within the time  specified  herein,
the Option shall  terminate,  and the Shares covered by such Option shall revert
to the Plan.

               (d)  Death of  Optionee.  If an  Optionee  dies  while a  Service
Provider, the Option may be exercised within such period of time as is specified
in the Option  Agreement  (but in no event later than the expiration of the term
of such Option as set forth in the Notice of Grant), by the Optionee's estate or
by a person  who  acquires  the  right to  exercise  the  Option by  bequest  or
inheritance,  but only to the  extent  that the  Option is vested on the date of
death.  In the absence of a specified time in the Option  Agreement,  the Option
shall  remain  exercisable  for twelve  (12)  months  following  the  Optionee's
termination.  If, at the time of death,  the Optionee is not vested as to his or
her entire  Option,  the Shares  covered by the  unvested  portion of the Option
shall  immediately  revert to the  Plan.  The  Option  may be  exercised  by the
executor or administrator of the Optionee's estate or, if none, by the person(s)
entitled to exercise the Option under the Optionee's will or the laws of descent
or  distribution.  If the Option is not so exercised  within the time  specified
herein, the Option shall terminate,  and the Shares covered by such Option shall
revert to the Plan.
               (e) Buyout Provisions. The Administrator may at any time offer to
buy out for a payment in cash or Shares, an Option  previously  granted based on
such terms and conditions as the  Administrator  shall establish and communicate
to the Optionee at the time that such offer is made.

        11.  Non-Transferability of Options . Unless determined otherwise by the
Administrator,  an  Option  may not be sold,  pledged,  assigned,  hypothecated,
transferred,  or disposed of in any manner  other than by will or by the laws of
descent  or  distribution  and may be  exercised,  during  the  lifetime  of the
Optionee,   only  by  the  Optionee.   If  the  Administrator  makes  an  Option
transferable,  such Option shall contain such additional terms and conditions as
the Administrator deems appropriate.

        12. Adjustments Upon Changes in Capitalization,  Dissolution,  Merger or
Asset Sale.

               (a) Changes in Capitalization.  Subject to any required action by
the shareholders of the Company, the number of shares of Common Stock covered by
each  outstanding  Option,  and the number of shares of Common  Stock which have
been  authorized for issuance under the Plan but as to which no Options have yet
been  granted  or which  have been  returned  to the Plan upon  cancellation  or
expiration of an Option,  as well as the price per share of Common Stock covered
by each such  outstanding  Option,  shall be  proportionately  adjusted  for any
increase or decrease in the number of issued  shares of Common  Stock  resulting
from a  stock  split,  reverse  stock  split,  stock  dividend,  combination  or
reclassification  of the Common Stock,  or any other increase or decrease in the
number  of  issued  shares  of  Common  Stock   effected   without   receipt  of
consideration  by  the  Company;  provided,  however,  that  conversion  of  any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of  consideration."  Such adjustment shall be made by the Board,
whose  determination  in that respect  shall be final,  binding and  conclusive.
Except as  expressly  provided  herein,  no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class,
shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of shares of Common Stock subject to an Option.

               (b)  Dissolution  or  Liquidation.  In the event of the  proposed
dissolution or liquidation of the Company,  the Administrator  shall notify each
Optionee as soon as  practicable  prior to the  effective  date of such proposed
transaction.  The Administrator in its discretion may provide for an Optionee to
have the right to exercise  his or her Option  until ten (10) days prior to such
transaction as to all of the Optioned Stock covered thereby, including Shares as
to which the  Option  would not  otherwise  be  exercisable.  In  addition,  the
Administrator  may provide that any Company  repurchase option applicable to any
Shares  purchased  upon exercise of an Option shall lapse as to all such Shares,
provided the proposed  dissolution or liquidation takes place at the time and in
the manner contemplated.  To the extent it has not been previously exercised, an
Option will terminate  immediately  prior to the  consummation  of such proposed
action.

               (c) Change of Control.  Upon or in connection with an acquisition
of the Company in a transaction or series of related transactions  consisting of
a merger, purchase of outstanding stock, sale of all or substantially all of the
Company's  assets,  or other form of business  acquisition or  combination,  and
which  results in a change in control of the Company  (the  "Acquisition"),  all
rights to exercise this Option or to acquire any shares of stock hereunder shall
automatically  terminate except as provided in this Section.  At such time prior
to the  consummation  of the  Acquisition  as the Committee  shall  designate by
written  notice to the  Optionee,  the Optionee or other person then entitled to
exercise  this Option shall have the right to exercise  the vested,  unexercised
portion of this Option which would,  but for this  Section,  otherwise be vested
and exercisable as of the date on which the Acquisition  occurs. If provision is
made in writing in connection  with the  Acquisition  for the assumption of this
Option, or the substitution for this Option of an option covering the stock of a
successor  employer  corporation,  or  a  parent  or  subsidiary  thereof,  with
appropriate adjustments, if any, in accordance with the applicable provisions of
the Plan as to the  number  and kind of  shares  optioned  and  their  exercises
prices,  then the Optionee shall elect in writing,  within time limits as may be
designated in written  notice from the Committee to the Optionee,  to accept the
assumed or substituted option arrangements, or, in lieu thereof, to exercise the
Option to the extent permitted under this Section, but the Optionee shall not be
entitled in any event to accept the  benefits,  in whole or in part,  of both of
those  alternatives.  The  Optionee  agrees  that  failure  to timely  accept or
exercise  rights under this Section by written  confirmation  designated in form
and  substance  by the  Committee  shall  forever  bar and  release  any  rights
otherwise granted to the Optionee under this Section or other provisions of this
Option.  The Optionee shall have no right to require that this Option be assumed
or replaced with a substitute option in connection with any Acquisition.

        13.  Date of  Grant.  The date of grant of an Option  shall be,  for all
purposes,  the date on which the Administrator makes the determination  granting
such Option,  or such other later date as is  determined  by the  Administrator.
Notice  of the  determination  shall  be  provided  to each  Optionee  within  a
reasonable time after the date of such grant.

        14. Amendment and Termination of the Plan.

               (a)     Amendment  and  Termination.  The Board may at any time
     amend, alter, suspend or terminate the Plan.

               (b) Effect of Amendment or Termination. No amendment, alteration,
suspension or  termination  of the Plan shall impair the rights of any Optionee,
unless mutually  agreed  otherwise  between the Optionee and the  Administrator,
which  agreement  must be in writing and signed by the Optionee and the Company.
Termination of the Plan shall not affect the Administrator's ability to exercise
the powers  granted to it hereunder  with respect to options  granted  under the
Plan prior to the date of such termination.

        15. Conditions Upon Issuance of Shares.

               (a) Legal Compliance.  Shares shall not be issued pursuant to the
exercise of an Option  unless the  exercise of such Option and the  issuance and
delivery of such Shares shall comply with  Applicable  Laws and shall be further
subject  to the  approval  of  counsel  for the  Company  with  respect  to such
compliance.

               (b) Investment Representations. As a condition to the exercise of
an Option the Company may require the person exercising such Option to represent
and warrant at the time of any such exercise that the Shares are being purchased
only for investment and without any present intention to sell or distribute such
Shares if, in the opinion of counsel for the Company,  such a representation  is
required.

        16.  Inability  to Obtain  Authority.  The  inability  of the Company to
obtain authority from any regulatory body having  jurisdiction,  which authority
is deemed by the  Company's  counsel to be necessary to the lawful  issuance and
sale of any Shares  hereunder,  shall  relieve the Company of any  liability  in
respect of the failure to issue or sell such  Shares as to which such  requisite
authority shall not have been obtained.
        17.  Reservation of Shares.  The Company,  during the term of this Plan,
will at all times reserve and keep  available  such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

II.     AGREEMENT

        1. Grant of Option.  The Plan Administrator of the Company hereby grants
to the  Optionee  named  in the  Notice  of  Grant  attached  as  Part I of this
Agreement  (the  "Optionee")  an option (the "Option") to purchase the number of
Shares, as set forth in the Notice of Grant, at the exercise price per share set
forth in the Notice of Grant (the  "Exercise  Price"),  subject to the terms and
conditions of the Plan,  which is incorporated  herein by reference.  Subject to
Section  14(b) of the Plan,  in the event of a  conflict  between  the terms and
conditions of the Plan and the terms and  conditions  of this Option  Agreement,
the terms and conditions of the Plan shall prevail.

        2.     Exercise of Option.

               (a) Right to Exercise. This Option is exercisable during its term
in accordance  with the Vesting  Schedule set out in the Notice of Grant and the
applicable provisions of the Plan and this Option Agreement.

               (b) Method of Exercise. This Option is exercisable by delivery of
an exercise notice,  in the form attached as Exhibit A (the "Exercise  Notice"),
which shall state the election to exercise  the Option,  the number of Shares in
respect of which the Option is being  exercised (the  "Exercised  Shares"),  and
such other  representations  and  agreements  as may be  required by the Company
pursuant to the provisions of the Plan.  The Exercise  Notice shall be completed
by the  Optionee  and  delivered  to  [Title].  The  Exercise  Notice  shall  be
accompanied  by  payment of the  aggregate  Exercise  Price as to all  Exercised
Shares.  This Option shall be deemed to be exercised upon receipt by the Company
of such fully executed  Exercise Notice  accompanied by such aggregate  Exercise
Price.

               No Shares shall be issued pursuant to the exercise of this Option
unless such issuance and exercise  complies with Applicable Laws.  Assuming such
compliance,  for income tax purposes the  Exercised  Shares shall be  considered
transferred  to the Optionee on the date the Option is exercised with respect to
such Exercised Shares.

        3. Method of Payment.  Payment of the aggregate  Exercise Price shall be
by any of the  following,  or a  combination  thereof,  at the  election  of the
Optionee:

               (a)     cash;

               (b)     check;

               (c)  consideration  received  by the  Company  under  a  cashless
exercise program implemented by the Company in connection with the Plan; or

               (d)  surrender  of other  Shares  which (i) in the case of Shares
acquired  upon  exercise of an option,  have been owned by the Optionee for more
than six (6) months on the date of surrender,  and (ii) have a Fair Market Value
on the date of surrender equal to the aggregate  Exercise Price of the Exercised
Shares.

        4.  Non-Transferability of Option. This Option may not be transferred in
any manner  otherwise than by will or by the laws of descent or distribution and
may be exercised during the lifetime of Optionee only by the Optionee. The terms
of the Plan and this  Option  Agreement  shall be  binding  upon the  executors,
administrators, heirs, successors and assigns of the Optionee.

        5. Term of Option. This Option may be exercised only within the term set
out in the  Notice  of  Grant,  and may be  exercised  during  such term only in
accordance with the Plan and the terms of this Option Agreement.

        6. Tax  Consequences.  Some of the federal tax consequences  relating to
this Option, as of the date of this Option, are set forth below. THIS SUMMARY IS
NECESSARILY INCOMPLETE,  AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.
THE  OPTIONEE  SHOULD  CONSULT A TAX ADVISER  BEFORE  EXERCISING  THIS OPTION OR
DISPOSING OF THE SHARES.

               (a) Exercising the Option. The Optionee may incur regular federal
income tax  liability  upon  exercise of an NSO. The Optionee will be treated as
having received compensation income (taxable at ordinary income tax rates) equal
to the excess,  if any, of the Fair Market Value of the Exercised  Shares on the
date of exercise  over their  aggregate  Exercise  Price.  If the Optionee is an
Employee or a former Employee, the Company will be required to withhold from his
or her  compensation  or collect from Optionee and pay to the applicable  taxing
authorities an amount in cash equal to a percentage of this compensation  income
at the time of  exercise,  and may  refuse to honor the  exercise  and refuse to
deliver  Shares if such  withholding  amounts are not  delivered  at the time of
exercise.

               (b)  Disposition of Shares.  If the Optionee holds NSO Shares for
at least one year,  any gain  realized  on  disposition  of the  Shares  will be
treated as long-term capital gain for federal income tax purposes.

        7. Entire Agreement;  Governing Law. The Plan is incorporated  herein by
reference. The Plan and this Option Agreement constitute the entire agreement of
the parties with  respect to the subject  matter  hereof and  supersede in their
entirety all prior  undertakings and agreements of the Company and Optionee with
respect to the subject matter hereof,  and may not be modified  adversely to the
Optionee's  interest  except by means of a writing  signed  by the  Company  and
Optionee.  This agreement is governed by the internal  substantive laws, but not
the choice of law rules, of California.

        8. NO GUARANTEE OF CONTINUED SERVICE.  OPTIONEE  ACKNOWLEDGES AND AGREES
THAT THE VESTING OF SHARES  PURSUANT TO THE  VESTING  SCHEDULE  HEREOF IS EARNED
ONLY BY  CONTINUING  AS A SERVICE  PROVIDER AT THE WILL OF THE COMPANY  (AND NOT
THROUGH THE ACT OF BEING HIRED,  BEING  GRANTED AN OPTION OR  PURCHASING  SHARES
HEREUNDER).  OPTIONEE FURTHER  ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT,  THE

                                    1.       Multiple Administrative Bodies. 
     The Plan may be  administered  by  different  Committees  with  respect  to
different groups of Service Providers.

                                    1.       Section 162(m). To the extent that 
     the Administrator  determines it to be desirable to qualify Options granted
hereunder  as  "performance-based  compensation"  within the  meaning of Section
162(m) of the Code, the Plan shall be administered by a Committee of two or more
"outside directors" within the meaning of Section 162(m) of the Code.
                                  
                                    1.       Rule 16b-3.  To the extent 
     desirable to qualify transactions hereunder as exempt under Rule 16b-3, the
transactions   contemplated   hereunder  shall  be  structured  to  satisfy  the
requirements for exemption under Rule 16b-3.

                                    1.       Other Administration.  Other than
     as provided above, the Plan shall be administered by (A) the Board or (B) a
Committee, which committee shall be constituted to satisfy Applicable Laws.

                  (b) Powers of the Administrator.  Subject to the provisions of
the  Plan,  and in the  case of a  Committee,  subject  to the  specific  duties
delegated  by the Board to such  Committee,  the  Administrator  shall  have the
authority, in its discretion:

                                    (a)      to determine the Fair Market Value
     of the Common Stock, in accordance with Section 2(n) of the Plan;

                                    (a)      to select the Consultants and 
     Employees  to  whom  Options  and  Stock  Purchase  Rights  may be  granted
hereunder;

                                    (a)      to determine whether and to what 
     extent Options and Stock Purchase  Rights or any combination  thereof,  are
granted hereunder;

                                    (a)      to determine the number of shares 
     of Common  Stock to be covered  by each  Option  and Stock  Purchase  Right
granted hereunder;

                                    (a)      to approve forms of agreement for 
use under the Plan;

                                    (a)      to determine the terms and 
     conditions,  not  inconsistent  with the  terms of the  Plan,  of any award
granted hereunder.  Such terms and conditions  include,  but are not limited to,
the exercise price,  the time or times when Options or Stock Purchase Rights may
be exercised (which may be based on performance  criteria),  and any restriction
or limitation,  or any waiver of forfeiture restrictions regarding any Option or
Stock Purchase Right or the shares of Common Stock  relating  thereto,  based in
each case on such factors as the  Administrator,  in its sole discretion,  shall
determine;
                           (b)              to reduce the exercise price of any 
     Option or Stock Purchase Right to the then current Fair Market Value if the
Fair Market Value of the Common Stock  covered by such Option or Stock  Purchase
Right shall have declined since the date the Option was granted;

                           (a)              to construe and interpret the terms 
of the Plan;

                           (a)              to prescribe, amend and rescind 
     rules and regulations relating to the Plan, including rules and regulations
relating to sub-plans  established  for the purpose of qualifying  for preferred
tax treatment under foreign tax laws;

                           (a)              to modify or amend each Option or 
     Stock Purchase Right (subject to Section 15(c) of the Plan),  including the
discretionary authority to extend the post-termination  exercisability period of
Options longer than is otherwise provided for in the Plan;

                           (a)              to authorize any person to execute 
     on behalf of the Company any instrument  required to effect the grant of an
Option or Stock Purchase Right previously granted by the Administrator;
                          
                           (a)              to allow Optionees to satisfy 
     withholding tax  obligations by electing to have the Company  withhold from
the Shares to be issued upon exercise of an Option or Stock  Purchase Right that
number of Shares  having a Fair Market Value equal to the amount  required to be
withheld. The Fair Market Value of the Shares to be withheld shall be determined
on the date  that the  amount of tax to be  withheld  is to be  determined.  All
elections by an Optionee to have Shares  withheld for this purpose shall be made
in such form and under such conditions as the  Administrator  may deem necessary
or advisable;
                           (a)      to institute an Option Exchange Program;

                           (a)      to determine the terms and restrictions 
     applicable to Options and Stock Purchase  Rights and any Restricted  Stock;
and

                           (a)      to make all other determinations deemed 
     necessary or advisable for administering the Plan.

                  (c) Effect of Administrator's  Decision.  The  Administrator's
decisions,  determinations and interpretations shall be final and binding on all
Optionees and any other holders of Options or Stock Purchase Rights.

                  I. Eligibility.  Nonstatutory Stock Options and Stock Purchase
Rights may be granted to Employees and Consultants.  Incentive Stock Options may
be granted only to Employees.  If otherwise eligible,  an Employee or Consultant
who has been granted an Option or Stock Purchase Right may be granted additional
Options or Stock Purchase Rights.

         I.           Limitations.

                  (1) Each Option shall be  designated in the Notice of Grant as
either an  Incentive  Stock  Option or a  Nonstatutory  Stock  Option.  However,
notwithstanding such designations,  to the extent that the aggregate Fair Market
Value:

                           (i)      of Shares subject to an Optionee's incentive
     stock options granted by the Company, any Parent or Subsidiary, which

                           (ii) become exercisable for the first time during any
calendar year (under all plans of the
Company or any Parent or Subsidiary)

exceeds  $100,000,  such excess Options shall be treated as  Nonstatutory  Stock
Options.  For purposes of this Section  6(a),  incentive  stock options shall be
taken into account in the order in which they were granted,  and the Fair Market
Value of the Shares shall be determined as of the time of grant.

                           (1)       Neither the Plan nor any Option or Stock 
     Purchase  Right shall  confer upon an  Optionee  any right with  respect to
continuing  the  Optionee's  employment  or  consulting  relationship  with  the
Company,  nor shall they interfere in any way with the  Optionee's  right or the
Company's right to terminate such  employment or consulting  relationship at any
time, with or without cause.

                           (1)       The following limitations shall apply to 
     grants of Options and Stock Purchase Rights to Employees:

                           (i)      No Employee shall be granted, in any fiscal 
     year of the Company,  Options and Stock  Purchase  Rights to purchase  more
than 250,000 Shares.

                           (ii) The  foregoing  limitations  shall  be  adjusted
proportionately in connection with any change in
the Company's capitalization as described in Section 13 hereof.

                           (iii)  If  an  Option  or  Stock  Purchase  Right  is
     canceled  in the same  fiscal  year of the  Company in which it was granted
(other than in connection with a transaction described in Section 13 hereof, the
canceled  Option or Stock Purchase  Right will be counted  against the limit set
forth in Section 6(c)(i) hereof.  For this purpose,  if the exercise price of an
Option or Stock Purchase Right is reduced,  the transaction will be treated as a
cancellation of the Option or Stock Purchase Right and the grant of a new Option
or Stock Purchase Right.

                  I. Term of Plan.  Subject to Section 19 of the Plan,  the Plan
shall become effective upon the earlier to occur of its adoption by the Board or
its  approval by the  shareholders  of the Company as described in Section 19 of
the Plan.  It shall  continue  in  effect  for a term of ten (10)  years  unless
terminated earlier under Section 15 of the Plan.

                  II. Term of Option. The term of each Option shall be stated in
the Notice of Grant;  provided,  however,  that the term shall be ten (10) years
from the date of grant or such  shorter term as may be provided in the Notice of
Grant.  However, in the case of an Incentive Stock Option granted to an Optionee
who, at the time the Incentive Stock Option is granted,  owns stock representing
more than ten percent  (10%) of the voting  power of all classes of stock of the
Company or any Parent or  Subsidiary,  the term of the  Incentive  Stock  Option
shall be five (5) years  from the date of grant or such  shorter  term as may be
provided in the Notice of Grant.

                  I.        Option Exercise Price and Consideration.

                           (1)       Exercise Price.  The per share exercise 
     price for the Shares to be issued  pursuant to exercise of an Option  shall
be determined by the Administrator, subject to the following:

                           (a)         In the case of an Incentive Stock Option

                                    (A)     granted to an Employee who, at the 
     time the Option is granted,  owns stock  representing more than ten percent
(10%) of the voting  power of all  classes of stock of the Company or any Parent
or  Subsidiary,  the per Share  exercise price shall be no less than 110% of the
Fair Market Value per Share on the date of grant.

                                    (B)  granted to any  Employee  other than an
     Employee  described  in  paragraph  (A)immediately  above,  the  per  Share
exercise  price shall be no less than 100% of the Fair Market Value per Share on
the date of grant.
                           (a)         In the case of a Nonstatutory Stock
     Option,   the  per  Share   exercise  price  shall  be  determined  by  the
Administrator. In the case of a Nonstatutory Stock Option intended to qualify as
"performance-based  compensation"  within the  meaning of Section  162(m) of the
Code, the per Share exercise price shall be no less than 100% of the Fair Market
Value per Share on the date of grant.

                           (a)        Notwithstanding the foregoing, Options may
     be granted  with a per Share  exercise  price of less than 100% of the Fair
Market  Value  per  Share  on the date of grant  pursuant  to a merger  or other
corporate transaction.
                           (1)       Waiting Period and Exercise Dates.  At the 
     time an Option is granted,  the  Administrator  shall fix the period within
which the Option may be exercised and shall determine any conditions  which must
be satisfied before the Option may be exercised.  In so doing, the Administrator
may  specify  that an Option  may not be  exercised  until the  completion  of a
service period.

                  (1) Form of Consideration.  The Administrator  shall determine
the acceptable  form of  consideration  for exercising an Option,  including the
method of payment.  In the case of an Incentive Stock Option,  the Administrator
shall determine the acceptable form of consideration at the time of grant.  Such
consideration may consist entirely of:

                           (i) cash,

                           (ii) check,

                           (iii) promissory note,

                           (iv) other Shares which (A) in the case of Shares 
     acquired  upon  exercise of an option,  have been owned by the Optionee for
more than six months on the date of surrender,  and (B) have a Fair Market Value
on the date of surrender equal to the aggregate  exercise price of the Shares as
to which said Option shall be exercised,

                           (v) delivery of a properly executed exercise notice 
     together with  irrevocable  instructions to a broker to promptly deliver to
the Company  the amount of sale or loan  proceeds  required to pay the  exercise
price,
                           (vi)     a reduction in the amount of any Company
     liability to the  Optionee,  including any  liability  attributable  to the
Optionee's participation in any Company-sponsored  deferred compensation program
or arrangement;
                           (vii) any combination of the foregoing methods of 
payment, or

                           (viii) such other consideration and method of payment
for the issuance of Shares to the extent permitted by Applicable Laws.

                  I.        Exercise of Option.

                           (1)       Procedure for Exercise; Rights as a 
     Shareholder. Any Option granted hereunder shall be exercisable according to
the terms of the Plan and at such times and under such  conditions as determined
by the Administrator and set forth in the Option Agreement.

                           An Option may not be  exercised  for a fraction  of a
Share.

                           An Option shall be deemed exercised when the Company 
     receives:  (i) written  notice of exercise (in  accordance  with the Option
Agreement)  from the person  entitled  to  exercise  the  Option,  and (ii) full
payment  for the Shares  with  respect to which the  Option is  exercised.  Full
payment may consist of any consideration and method of payment authorized by the
Administrator  and permitted by the Option Agreement and the Plan. Shares issued
upon  exercise of an Option  shall be issued in the name of the  Optionee or, if
requested  by the  Optionee,  in the name of the Optionee and his or her spouse.
Until the stock  certificate  evidencing  such Shares is issued (as evidenced by
the  appropriate  entry on the  books  of the  Company  or of a duly  authorized
transfer  agent of the  Company),  no right to vote or receive  dividends or any
other rights as a  shareholder  shall exist with respect to the Optioned  Stock,
notwithstanding the exercise of the Option. The Company shall issue (or cause to
be issued) such stock  certificate  promptly  after the Option is exercised.  No
adjustment  will be made for a dividend or other right for which the record date
is prior to the date the stock  certificate  is issued,  except as  provided  in
Section 13 of the Plan.

                           Exercising an Option in any manner shall decrease the
number of Shares  thereafter  available,  both for purposes of the Plan and
for sale  under the  Option,  by the  number of Shares as to which the Option is
exercised.

                           (1)       Termination of Employment or Consulting 
     Relationship.  In the event an Optionee's  Continuous Status as an Employee
or Consultant  terminates  (other than upon the Optionee's death or Disability),
the Optionee may exercise his or her Option, but only within such period of time
as is determined by the Administrator,  and only to the extent that the Optionee
was  entitled to exercise it at the date of  termination  (but in no event later
than the  expiration  of the term of such  Option as set forth in the  Notice of
Grant).  In the case of an  Incentive  Stock  Option,  the  Administrator  shall
determine  such period of time (in no event to exceed  ninety (90) days from the
date of termination) when the Option is granted. If, at the date of termination,
the Optionee is not entitled to exercise  his or her entire  Option,  the Shares
covered by the unexercisable portion of the Option shall revert to the Plan. If,
after  termination,  the Optionee does not exercise his or her Option within the
time specified by the Administrator,  the Option shall terminate, and the Shares
covered by such Option shall revert to the Plan.

                  Notwithstanding  the  above,  in the  event  of an  Optionee's
change in status from Consultant or Director to Employee or Employee or Director
to Consultant, an Optionee's Continuous Status as a Director or Consultant shall
not  automatically  terminate  solely  as a result  of such  change  in  status.
However,  in such event,  an Incentive  Stock Option held by the Optionee  shall
cease to be treated as an  Incentive  Stock  Option and shall be treated for tax
purposes as a Nonstatutory  Stock Option three months and one day following such
change of status from an Employee to a Consultant.

                           (1)       Disability of Optionee.  In the event an 
     Optionee's  Continuous Status as an Employee or Consultant  terminates as a
result of the  Optionee's  Disability,  the  Optionee  may  exercise  his or her
Option,  but only within  twelve (12) months from the date of such  termination,
and only to the extent that the Optionee was entitled to exercise it at the date
of such  termination  (but in no event later than the  expiration of the term of
such  Option  as set  forth  in the  Notice  of  Grant).  If,  at  the  date  of
termination,  the Optionee is not entitled to exercise his or her entire Option,
the Shares  covered by the  unexercisable  portion of the Option shall revert to
the Plan.  If,  after  termination,  the  Optionee  does not exercise his or her
Option within the time specified  herein,  the Option shall  terminate,  and the
Shares covered by such Option shall revert to the Plan.
                           (1)       Death of Optionee.  In the event of the
     death of an  Optionee,  the Option  may be  exercised,  at any time  within
twelve (12) months  following  the date of death (but in no event later than the
expiration  of the term of such Option as set forth in the Notice of Grant),  by
the  Optionee's  estate or by a person who  acquired  the right to exercise  the
Option by  bequest or  inheritance,  but only to the  extent  the  Optionee  was
entitled to exercise the Option at the date of death.  If, at the time of death,
the Optionee was not entitled to exercise his or her entire  Option,  the Shares
covered by the unexercisable portion of the Option shall revert to the Plan. If,
after  death,  the  Optionee's  estate  or a person  who  acquired  the right to
exercise  the Option by  bequest or  inheritance  does not  exercise  the Option
within the time specified  herein,  the Option shall  terminate,  and the Shares
covered by such Option shall revert to the Plan.

                  I.        Stock Purchase Rights.

                  (a) Rights to Purchase.  Stock  Purchase  Rights may be issued
either alone,  in addition to, or in tandem with other awards  granted under the
Plan  and/or  cash  awards  made  outside of the Plan.  After the  Administrator
determines  that it will offer Stock  Purchase  Rights under the Plan,  it shall
advise the  offeree  in  writing,  by means of a Notice of Grant,  of the terms,
conditions and restrictions related to the offer, including the number of Shares
that the offeree  shall be entitled to purchase,  the price to be paid,  and the
time within  which the offeree  must accept such offer,  which shall in no event
exceed  six (6)  months  from the date  upon  which the  Administrator  made the
determination  to grant the Stock Purchase Right. The offer shall be accepted by
execution of a Restricted Stock Purchase Agreement in the form determined by the
Administrator.

                  (b) Repurchase  Option.  Unless the  Administrator  determines
otherwise,  the Restricted  Stock Purchase  Agreement  shall grant the Company a
repurchase option  exercisable upon the voluntary or involuntary  termination of
the purchaser's  employment with the Company for any reason  (including death or
Disability).   The  purchase  price  for  Shares  repurchased  pursuant  to  the
Restricted  Stock  purchase  agreement  shall be the original  price paid by the
purchaser and may be paid by cancellation  of any  indebtedness of the purchaser
to the Company.  The repurchase  option shall lapse at a rate  determined by the
Administrator.

                  (c) Other Provisions.  The Restricted Stock Purchase March 25,
1997  Agreement  shall contain such other terms,  provisions  and conditions not
inconsistent with the Plan as may be determined by the Administrator in its sole
discretion.  In addition, the provisions of Restricted Stock Purchase Agreements
need not be the same with respect to each purchaser.

                  (d) Rights as a Shareholder.  Once the Stock Purchase Right is
exercised,  the  purchaser  shall  have  the  rights  equivalent  to  those of a
shareholder, and shall be a shareholder when his or her purchase is entered upon
the records of the duly authorized  transfer agent of the Company. No adjustment
will be made for a dividend or other right for which the record date is prior to
the date the Stock Purchase Right is exercised, except as provided in Section 13
of the Plan.
                  I.  Non-Transferability  of Options and Stock Purchase Rights.
Unless determined  otherwise by the  Administrator,  an Option or Stock Purchase
Right may not be sold, pledged, assigned, hypothecated, transferred, or disposed
of in any manner  other  than by will or by the laws of descent or  distribution
and may be exercised, during the lifetime of the Optionee, only by the Optionee.
If the Administrator makes an Option or Stock Purchase Right transferable,  such
Option  or  Stock  Purchase  Right  shall  contain  such  additional  terms  and
conditions as the Administrator deems appropriate.

                           I.        Adjustments Upon Changes in Capitalization,
 Dissolution or Merger.

                  (1) Changes in Capitalization.  Subject to any required action
by the shareholders of the Company, the number of shares of Common Stock covered
by each outstanding Option and Stock Purchase Right, and the number of shares of
Common Stock which have been  authorized  for issuance  under the Plan but as to
which no Options or Stock  Purchase  Rights have yet been  granted or which have
been returned to the Plan upon  cancellation or expiration of an Option or Stock
Purchase  Right,  as well as the price per share of Common Stock covered by each
such  outstanding  Option  or Stock  Purchase  Right,  shall be  proportionately
adjusted for any  increase or decrease in the number of issued  shares of Common
Stock  resulting  from a stock  split,  reverse  stock  split,  stock  dividend,
combination or  reclassification  of the Common Stock,  or any other increase or
decrease in the number of issued shares of Common Stock effected without receipt
of  consideration  by the Company;  provided,  however,  that  conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of  consideration."  Such adjustment shall be made by the Board,
whose  determination  in that respect  shall be final,  binding and  conclusive.
Except as  expressly  provided  herein,  no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class,
shall affect, and no adjustment by reason thereof shall be made with respect to,
the  number or price of shares of  Common  Stock  subject  to an Option or Stock
Purchase Right.

                           (1)       Dissolution or Liquidation.  In the event 
of the proposed dissolution or liquidation of the
     Company,  to the extent that an Option or Stock Purchase Right has not been
previously exercised, it will terminate immediately prior to the consummation of
such proposed  action.  The Board may, in the exercise of its sole discretion in
such instances,  declare that any Option or Stock Purchase Right shall terminate
as of a date fixed by the Board and give each Optionee the right to exercise his
or her  Option  or Stock  Purchase  Right as to all or any part of the  Optioned
Stock, including Shares as to which the Option or Stock Purchase Right would not
otherwise be exercisable.

                           (1)       Merger or Asset Sale.  In the event of a 
     merger of the  Company  with or into  another  corporation,  or the sale of
substantially  all of the assets of the  Company,  each  outstanding  Option and
Stock  Purchase  Right may be  assumed or an  equivalent  option or right may be
substituted  by the  successor  corporation  or a Parent  or  Subsidiary  of the
successor corporation. In the event the successor corporation does not assume or
substitute the Options and Stock Purchase Rights,  then the Administrator  shall
provide for the  Optionee  to fully vest in and have the right to  exercise  the
Option or Stock  Purchase  Right as to all or a portion of the  Optioned  Stock,
including Shares as to which it would not otherwise be vested or exercisable. If
the Administrator makes an Option or Stock Purchase Right exercisable in lieu of
assumption  or  substitution  in the  event of a merger or sale of  assets,  the
Administrator  shall notify the Optionee that the Option or Stock Purchase Right
shall be fully vested and exercisable for a period of fifteen (15) days from the
date of such notice,  and the Option or Stock Purchase Right will terminate upon
the expiration of such period. For the purposes of this paragraph, the Option or
Stock  Purchase  Right shall be considered  assumed if,  following the merger or
sale of assets,  the option or right  confers  the right to  purchase,  for each
Share  of  Optioned  Stock  subject  to  the  Option  or  Stock  Purchase  Right
immediately prior to the merger or sale of assets,  the  consideration  (whether
stock,  cash, or other securities or property) received in the merger or sale of
assets by holders of Common Stock for each Share held on the  effective  date of
the transaction (and if holders were offered a choice of consideration, the type
of consideration chosen by the holders of a majority of the outstanding Shares);
provided,  however, that if such consideration received in the merger or sale of
assets was not solely common stock of the successor  corporation  or its Parent,
the Administrator  may, with the consent of the successor  corporation,  provide
for the  consideration  to be received  upon the exercise of the Option or Stock
Purchase Right,  for each Share of Optioned Stock subject to the Option or Stock
Purchase  Right,  to be solely common stock of the successor  corporation or its
Parent  equal in fair market  value to the per share  consideration  received by
holders of Common Stock in the merger or sale of assets.

                  I.  Date of  Grant.  The date of grant of an  Option  or Stock
Purchase Right shall be, for all purposes,  the date on which the  Administrator
makes the  determination  granting such Option or Stock Purchase  Right, or such
other  later  date  as  is  determined  by  the  Administrator.  Notice  of  the
determination  shall be provided to each Optionee within a reasonable time after
the date of such grant.

                  I.        Amendment and Termination of the Plan.

                           (1)       Amendment and Termination.  The Board may
     at any time amend, alter, suspend or terminate the Plan.

                  (1) Shareholder Approval. The Company shall obtain shareholder
approval of any Plan  amendment to the extent  necessary and desirable to comply
with Sections  162(m) and 422 of the Code (or any  successor  rule or statute or
other  applicable  law, rule or regulation,  including the  requirements  of any
exchange  or  quotation  system on which the Common  Stock is listed or quoted).
Such shareholder approval,  if required,  shall be obtained in such a manner and
to such a degree as is required by the applicable law, rule or regulation.

                           (1)       Effect of Amendment or Termination.  No 
     amendment,  alteration,  suspension or termination of the Plan shall impair
the  rights of any  Optionee,  unless  mutually  agreed  otherwise  between  the
Optionee and the Administrator, which agreement must be in writing and signed by
the Optionee and the Company.

                  II.       Conditions Upon Issuance of Shares.

                  (1) Legal  Compliance.  Shares shall not be issued pursuant to
the  exercise of an Option or Stock  Purchase  Right unless the exercise of such
Option or Stock  Purchase  Right and the  issuance  and  delivery of such Shares
shall comply with all relevant provisions of law, including, without limitation,
the  Securities  Act of 1933,  as  amended,  the  Exchange  Act,  the  rules and
regulations promulgated  thereunder,  and the requirements of any stock exchange
or  quotation  system  upon which the  Shares may then be listed or quoted,  and
shall be further subject to the approval of counsel for the Company with respect
to such compliance.

                  (1) Investment Representations. As a condition to the exercise
of an Option or Stock  Purchase  Right,  the  Company  may  require  the  person
exercising  such Option or Stock  Purchase Right to represent and warrant at the
time of any  such  exercise  that  the  Shares  are  being  purchased  only  for
investment and without any present  intention to sell or distribute  such Shares
if,  in the  opinion  of  counsel  for the  Company,  such a  representation  is
required.

         I.          Liability of Company.

                  (1)  Inability  to  Obtain  Authority.  The  inability  of the
Company to obtain authority from any regulatory body having jurisdiction,  which
authority  is deemed by the  Company's  counsel  to be  necessary  to the lawful
issuance  and sale of any Shares  hereunder,  shall  relieve  the Company of any
liability  in  respect of the  failure to issue or sell such  Shares as to which
such requisite authority shall not have been obtained.

                  (1) Grants Exceeding  Allotted  Shares.  If the Optioned Stock
covered by an Option or Stock Purchase  Right exceeds,  as of the date of grant,
the  number of Shares  which may be  issued  under the Plan  without  additional
shareholder  approval,  such Option or Stock Purchase shall be void with respect
to such excess  Optioned  Stock,  unless  shareholder  approval of an  amendment
sufficiently  increasing  the  number  of Shares  subject  to the Plan is timely
obtained in accordance with Section 15(b) of the Plan.

                  I. Reservation of Shares. The Company, during the term of this
Plan,  will at all times  reserve  and keep  available  such number of Shares as
shall be sufficient to satisfy the requirements of the Plan.

                  I.  Shareholder  Approval.  Continuance  of the Plan  shall be
subject to approval by the shareholders of the Company within twelve (12) months
before or after the date the Plan is adopted. Such shareholder approval shall be
obtained in the manner and to the degree required under  applicable  federal and
state law.





                                                                     EXHIBIT 4.3
                            MICRO LINEAR CORPORATION

                        1994 EMPLOYEE STOCK PURCHASE PLAN

                        (as amended through May 28, 1997)

         The following  constitute  the  provisions  of the 1994 Employee  Stock
Purchase Plan of Micro Linear Corporation.

                  I. Purpose. The purpose of the Plan is to provide employees of
the Company and its  Designated  Subsidiaries  with an  opportunity  to purchase
Common Stock of the Company through accumulated  payroll  deductions.  It is the
intention of the Company to have the Plan qualify as an "Employee Stock Purchase
Plan" under Section 423 of the Internal  Revenue Code of 1986,  as amended.  The
provisions  of the Plan,  accordingly,  shall be  construed  so as to extend and
limit participation in a manner consistent with the requirements of that section
of the Code.

                  I.        Definitions.

                           A.        "Board" shall mean the Board of Directors 
of the Company.

                           A.        "Code" shall mean the Internal Revenue Code
 of 1986, as amended.

                           A.        "Common Stock" shall mean the Common Stock
 of the Company.

                           A.        "Company" shall mean Micro Linear
     Corporation,  a California corporation and any Designated Subsidiary of the
Company.

                           A.        "Compensation" shall mean all base straight
     time  gross  earnings  including  payments  for  overtime,  shift  premium,
incentive  compensation,  incentive payments,  commissions or other compensation
but excluding bonuses.

                           A.        "Designated Subsidiaries" shall mean the 
     Subsidiaries  which have been  designated by the Board from time to time in
its sole discretion as eligible to participate in the Plan.

                           A.        "Employee" shall mean any individual who is
     an employee of the Company for tax purposes whose customary employment with
the Company is at least twenty (20) hours per week and more than five (5) months
in any calendar  year.  For purposes of the Plan,  the  employment  relationship
shall be treated as continuing  intact while the  individual is on sick leave or
other  leave of  absence  approved  by the  Company.  Where the  period of leave
exceeds 90 days and the  individual's  right to  reemployment  is not guaranteed
either by statute or by contract, the employment  relationship will be deemed to
have terminated on the 91st day of such leave.
                           B.        "Enrollment Date" shall mean the first day 
of each Offering Period.

                           A.        "Exercise Date" shall mean the last day of 
each Offering Period.

                           A.        "Fair Market Value" shall mean, as of any
     date, the value of Common Stock determined as follows:

                                    1.       If the Common Stock is listed on 
     any  established  stock  exchange or a national  market  system,  including
without  limitation the Nasdaq  National  Market of the National  Association of
Securities Dealers,  Inc. Automated Quotation ("NASDAQ") System, its Fair Market
Value shall be the closing  sale price for the Common  Stock (or the mean of the
closing  bid and asked  prices,  if no sales were  reported),  as quoted on such
exchange (or the exchange  with the greatest  volume of trading in Common Stock)
or system on the date of such  determination,  as  reported  in The Wall  Street
Journal or such other source as the Board deems reliable, or;

                                    1.       If the Common Stock is quoted on 
     the NASDAQ  System (but not on the Nasdaq  National  Market  thereof) or is
regularly  quoted by a recognized  securities  dealer but selling prices are not
reported,  its Fair Market  Value shall be the mean of the closing bid and asked
prices for the Common  Stock on the date of such  determination,  as reported in
The Wall Street Journal or such other source as the Board deems reliable, or;

                                    1.       Notwithstanding paragraphs (1) and 
     (2), in the case of an Offering Period commencing  substantially concurrent
with the  Company's  initial  public  offering,  the Fair  Market  Value  may be
determined by the Board to be equal to the initial price to the public of shares
of Common Stock in such offering; or

                                    1.       In the absence of an established 
     market  for the  Common  Stock,  the Fair  Market  Value  thereof  shall be
determined in good faith by the Board.

                           A.        "Offering Period" shall mean a period of 
     approximately  six (6) months,  commencing  on the first Trading Day of the
Company's  first fiscal  quarter and  terminating on the last Trading Day of the
Company's  second fiscal quarter,  or commencing on the first Trading Day of the
Company's  third fiscal  quarter and  terminating on the last Trading Day of the
Company's fourth fiscal quarter,  during which an option granted pursuant to the
Plan may be exercised.  The duration of Offering Periods may be changed pursuant
to  Section 4 of this  Plan.  Notwithstanding  the  foregoing,  in the event the
Company shall effect an initial public  offering of Common Stock,  the Board may
determine  to commence  an Offering  Period  substantially  concurrent  with the
public offering,  such Offering Period to continue until the next succeeding May
31 or November 30 as the Board may determine.

                           A.        "Plan" shall mean this Employee Stock 
Purchase Plan.

                           A.        "Purchase Price" shall mean an amount 
     equal to 85% of the Fair  Market  Value of a share of  Common  Stock on the
Enrollment Date or on the Exercise Date, whichever is lower.

                           A.        "Reserves" shall mean the number of shares 
     of Common  Stock  covered by each option  under the Plan which have not yet
been  exercised  and the  number  of  shares of  Common  Stock  which  have been
authorized for issuance under the Plan but not yet placed under option.

                           A.        "Subsidiary" shall mean a corporation, 
     domestic  or foreign,  of which not less than 50% of the voting  shares are
held by the Company or a Subsidiary,  whether or not such corporation now exists
or is hereafter organized or acquired by the Company or a Subsidiary.

                  A.          "Trading Day" shall mean a day on which national 
     stock exchanges and The NASDAQ Stock Market are open for trading.

                  I.        Eligibility.

                           A.        Any Employee (as defined in Section 2(g)), 
     who shall be employed by the  Company on a given  Enrollment  Date shall be
eligible to participate in the Plan.

                           A.        Any provisions of the Plan to the contrary 
     notwithstanding,  no Employee shall be granted an option under the Plan (i)
to the extent,  immediately  after the grant, such Employee (or any other person
whose stock would be attributed to such Employee  pursuant to Section  424(d) of
the Code) would own capital stock of the Company and/or hold outstanding options
to  purchase  such  stock  possessing  five  percent  (5%) or more of the  total
combined  voting  power or  value of all  classes  of the  capital  stock of the
Company  or of any  Subsidiary,  or  (ii) to the  extent  his or her  rights  to
purchase  stock under all employee  stock  purchase plans of the Company and its
subsidiaries  to accrue at a rate which  exceeds  Twenty-Five  Thousand  Dollars
($25,000)  worth of stock  (determined at the fair market value of the shares at
the time such option is granted) for each  calendar year in which such option is
outstanding at any time.

                  I.  Offering  Periods.   The  Plan  shall  be  implemented  by
consecutive  Offering Periods with a new Offering Period commencing on the first
Trading Day of the Company's first and third fiscal  quarters,  or on such other
date as the Board shall determine, and continuing thereafter until terminated in
accordance with Section 19 hereof.  The Board shall have the power to change the
duration of Offering  Periods  (including the  commencement  dates thereof) with
respect to future  offerings  without  shareholder  approval  if such  change is
announced  at least  fifteen (15) days prior to the  scheduled  beginning of the
first Offering Period to be affected thereafter.

                  I.        Participation.

                           A.        An eligible Employee may become a 
     participant in the Plan by completing a subscription  agreement authorizing
payroll  deductions in the form of Exhibit A to this Plan and filing it with the
Company's payroll office prior to the applicable Enrollment Date.

                           A.        Payroll deductions for a participant shall 
     commence on the first payroll  following the Enrollment  Date and shall end
on the last  payroll  in the  Offering  Period to which  such  authorization  is
applicable,  unless sooner  terminated by the participant as provided in Section
10.

                  I.        Payroll Deductions.

                  (a) At the time a  participant  files his or her  subscription
agreement, he or she shall elect to have payroll deductions made on each pay day
during the Offering  Period in an amount not  exceeding ten percent (10%) of the
Compensation  which he or she  receives  on each  pay day  during  the  Offering
Period.

                  (b) All payroll  deductions  made for a  participant  shall be
credited  to his or her  account  under the Plan and will be  withheld  in whole
percentages  only. A participant may not make any additional  payments into such
account.

                  (c) A participant may discontinue his or her  participation in
the Plan as provided in Section 10 hereof,  or may increase or decrease the rate
of his or her payroll  deductions  during the Offering  Period by  completing or
filing with the Company a new  subscription  agreement  authorizing  a change in
payroll  deduction rate. The Board may, in its  discretion,  limit the number of
participation  rate changes during any Offering Period. The change in rate shall
be effective with the first full payroll period following five (5) business days
after the Company's receipt of the new subscription agreement unless the Company
elects to process a given change in participation  more quickly. A participant's
subscription  agreement shall remain in effect for successive  Offering  Periods
unless terminated as provided in Section 10 hereof.

                  (d) Notwithstanding the foregoing,  to the extent necessary to
comply  with  Section   423(b)(8)  of  the  Code  and  Section  3(b)  hereof,  a
participant's  payroll deductions may be decreased to 0% at such time during any
Offering Period which is scheduled to end during the current  calendar year (the
"Current  Offering  Period") that the aggregate of all payroll  deductions which
were previously used to purchase stock under the Plan in a prior Offering Period
which ended during that  calendar year plus all payroll  deductions  accumulated
with respect to the Current  Offering Period equal $21,250.  Payroll  deductions
shall  recommence  at the  rate  provided  in  such  participant's  subscription
agreement at the  beginning of the first  Offering  Period which is scheduled to
end in the following  calendar  year,  unless  terminated by the  participant as
provided in Section 10 hereof.

                  (e) At the time the option is exercised,  in whole or in part,
or at the time some or all of the  Company's  Common Stock issued under the Plan
is disposed of, the participant  must make adequate  provision for the Company's
federal, state, or other tax withholding  obligations,  if any, which arise upon
the exercise of the option or the  disposition of the Common Stock. At any time,
the Company may, but will not be obligated to,  withhold from the  participant's
compensation the amount necessary for the Company to meet applicable withholding
obligations, including any withholding required to make available to the Company
any tax  deductions or benefits  attributable  to sale or early  disposition  of
Common Stock by the Employee.

                  I. Grant of Option.  On the  Enrollment  Date of each Offering
Period,  each eligible  Employee  participating in such Offering Period shall be
granted an option to purchase on the Exercise Date of such  Offering  Period (at
the applicable  Purchase Price) up to a number of shares of the Company's Common
Stock  determined by dividing such  Employee's  payroll  deductions  accumulated
prior to such Exercise Date and retained in the Participant's  account as of the
Exercise Date by the applicable Purchase Price;  provided that in no event shall
an Employee be permitted  to purchase  during each  Offering  Period more than a
number of Shares  determined  by dividing  $12,500 by the Fair Market Value of a
share of the Company's Common Stock on the Enrollment Date, and provided further
that such  purchase  shall be subject to the  limitations  set forth in Sections
3(b) and 12 hereof.  Exercise of the option shall occur as provided in Section 8
hereof,  unless the participant has withdrawn pursuant to Section 10 hereof, and
shall expire on the last day of the Offering Period.

                  I. Exercise of Option. Unless a participant withdraws from the
Plan as  provided  in Section 10 below,  his or her option for the  purchase  of
shares shall be exercised  automatically  on the Exercise  Date, and the maximum
number of full shares subject to option shall be purchased for such  participant
at the applicable  Purchase Price with the accumulated payroll deductions in his
or her account. No fractional shares shall be purchased;  any payroll deductions
accumulated  in a  participant's  account which are not sufficient to purchase a
full share shall be retained in the  participant'  s account for the  subsequent
Offering Period, subject to earlier withdrawal by the participant as provided in
Section 10 hereof.  Any other monies left over in a participant's  account after
the Exercise Date shall be returned to the  participant.  During a participant's
lifetime,  a participant's  option to purchase  shares  hereunder is exercisable
only by him or her.

                  I. Delivery.  As promptly as  practicable  after each Exercise
Date on which a  purchase  of shares  occurs,  the  Company  shall  arrange  the
delivery to each participant,  as appropriate, of a certificate representing the
shares purchased upon exercise of his or her option.

                  I.        Withdrawal; Termination of Employment.

                           A.        A participant may withdraw all but not less
     than all the payroll deductions  credited to his or her account and not yet
used to exercise his or her option under the Plan at any time by giving  written
notice  to the  Company  in the  form  of  Exhibit  B to this  Plan.  All of the
participant's  payroll deductions credited to his or her account will be paid to
such  participant  promptly  after  receipt  of  notice of  withdrawal  and such
participant's  option for the Offering Period will be automatically  terminated,
and no further payroll deductions for the purchase of shares will be made during
the Offering Period. If a participant withdraws from an Offering Period, payroll
deductions  will not resume at the beginning of the succeeding  Offering  Period
unless the participant delivers to the Company a new subscription agreement.

                           A.        Upon a participant's ceasing to be an 
     Employee (as defined in Section 2(g) hereof) for any reason, he or she will
be deemed to have elected to withdraw  from the Plan and the payroll  deductions
credited to such  participant's  account during the Offering  Period but not yet
used to exercise the option will be returned to such participant or, in the case
of his or her death, to the person or persons  entitled thereto under Section 14
hereof,  and such  participant's  option will be automatically  terminated.  The
preceding sentence  notwithstanding,  a participant who receives payment in lieu
of notice of termination  of employment  shall be treated as continuing to be an
Employee for the participant's  customary number of hours per week of employment
during the period in which the participant is subject to such payment in lieu of
notice.

                           A.        A participant's withdrawal from an Offering
     Period will not have any effect upon his or her  eligibility to participate
in any  similar  plan  which may  hereafter  be  adopted  by the  Company  or in
succeeding Offering Periods which commence after the termination of the Offering
Period from which the participant withdraws.

                  I.        Interest.  No interest shall accrue on the payroll 
deductions of a participant in the Plan.

                  I.        Stock.

                           A.        The maximum number of shares of the 
     Company's  Common  Stock which shall be made  available  for sale under the
Plan  shall  be  455,000   shares,   subject  to  adjustment   upon  changes  in
capitalization  of the Company as  provided in Section 18 hereof.  If on a given
Exercise  Date the  number of shares  with  respect to which  options  are to be
exercised  exceeds  the  number of shares  then  available  under the Plan,  the
Company shall make a pro rata allocation of the shares  remaining  available for
purchase  in as  uniform  a  manner  as  shall  be  practicable  and as it shall
determine to be equitable.

                           A.        The participant will have no interest or 
     voting  right in shares  covered by his option  until such  option has been
exercised.

                           A.        Shares to be delivered to a participant 
     under the Plan will be registered in the name of the  participant or in the
name of the participant and his or her spouse.

                  I.        Administration.

                           A.        Administrative Body.  The Plan shall be 
     administered  by the Board or a committee of members of the Board appointed
by the  Board.  The  Board  or its  committee  shall  have  full  and  exclusive
discretionary authority to construe,  interpret and apply the terms of the Plan,
to determine  eligibility  and to adjudicate all disputed claims filed under the
Plan.  Every  finding,  decision  and  determination  made by the  Board  or its
committee  shall, to the full extent permitted by law, be final and binding upon
all parties.

                  I.        Designation of Beneficiary.

                           A.        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 an Exercise Date on which the option is exercised but prior
to  delivery  to such  participant  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 exercise of the option.

                           A.        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  and  in  the  absence  of a  beneficiary  validly
designated under the Plan who is living at the time of such participant's death,
the  Company   shall  deliver  such  shares  and/or  cash  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.

                  I.  Transferability.  Neither payroll deductions credited to a
participant's account nor any rights with regard to the exercise of an option or
to  receive  shares  under the Plan may be  assigned,  transferred,  pledged  or
otherwise  disposed of in any way (other  than by will,  the laws of descent and
distribution or as provided in Section 14 hereof) by the  participant.  Any such
attempt at assignment,  transfer,  pledge or other  disposition shall be without
effect,  except  that the  Company may treat such act as an election to withdraw
funds from an Offering Period in accordance with Section 10 hereof.

                  I. 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.

                  I. Reports.  Individual  accounts will be maintained  for each
participant  in the Plan.  Statements of account will be given to  participating
Employees  at least  annually,  which  statements  will set forth the amounts of
payroll  deductions,  the Purchase Price, the number of shares purchased and the
remaining cash balance, if any.

                  I.        Adjustments Upon Changes in Capitalization.

                  (a) Changes in Capitalization.  Subject to any required action
by the shareholders of the Company,  the Reserves as well as the price per share
of Common  Stock  covered by each  option  under the Plan which has not yet been
exercised shall be proportionately  adjusted for any increase or decrease in the
number of issued shares of Common Stock  resulting  from a stock split,  reverse
stock split,  stock  dividend,  combination  or  reclassification  of the Common
Stock, or any other increase or decrease in the number of shares of Common Stock
effected  without receipt of consideration  by the Company;  provided,  however,
that conversion of any convertible securities of the Company shall not be deemed
to have been "effected without receipt of consideration."  Such adjustment shall
be made by the  Board,  whose  determination  in that  respect  shall be  final,
binding and conclusive.  Except as expressly  provided  herein,  no issue by the
Company of shares of stock of any class, or securities  convertible  into shares
of stock of any class,  shall affect,  and no adjustment by reason thereof shall
be made with respect to, the number or price of shares of Common  Stock  subject
to an option.

                  (b) Dissolution or  Liquidation.  In the event of the proposed
dissolution or liquidation  of the Company,  the Offering  Period will terminate
immediately prior to the consummation of such proposed action,  unless otherwise
provided by the Board.

                  (c) Merger or Asset Sale.  In the event of a proposed  sale of
all or  substantially  all of the  assets of the  Company,  or the merger of the
Company  with or into another  corporation,  each option under the Plan shall be
assumed  or  an  equivalent  option  shall  be  substituted  by  such  successor
corporation  or a parent or subsidiary  of such  successor  corporation.  In the
event the successor corporation refuses to assume or substitute for the options,
then the Board shall  shorten the Offering  Period then in progress by setting a
new Exercise Date (the "New Exercise Date").  If the Board shortens the Offering
Period then in progress in lieu of assumption or  substitution in the event of a
merger or sale of assets, the Board shall notify each participant in writing, at
least ten (10) business days prior to the New Exercise  Date,  that the Exercise
Date for his  option  has been  changed  to the New  Exercise  Date and that his
option will be exercised automatically on the New Exercise Date, unless prior to
such date he has  withdrawn  from the Offering  Period as provided in Section 10
hereof.  For purposes of this paragraph,  an option granted under the Plan shall
be deemed to be assumed if,  following the sale of assets or merger,  the option
confers the right to  purchase,  for each share of option  stock  subject to the
option  immediately  prior to the sale of assets or  merger,  the  consideration
(whether stock,  cash or other  securities or property)  received in the sale of
assets or merger by holders of Common  Stock for each share of Common Stock held
on the  effective  date of the  transaction  (and if such holders were offered a
choice of  consideration,  the type of consideration  chosen by the holders of a
majority of the outstanding shares of Common Stock); provided,  however, that if
such  consideration  received  in the sale of assets or  merger  was not  solely
common stock of the successor  corporation  or its parent (as defined in Section
424(e)  of the  Code),  the  Board  may,  with  the  consent  of  the  successor
corporation,  provide for the  consideration to be received upon exercise of the
option to be solely  common  stock of the  successor  corporation  or its parent
equal in fair market value to the per share consideration received by holders of
Common Stock and the sale of assets or merger.

         The  Board  may,  if it so  determines  in the  exercise  of  its  sole
discretion, also make provision for adjusting the Reserves, as well as the price
per share of Common Stock covered by each outstanding  option,  in the event the
Company effects one or more reorganizations, recapitalizations, rights offerings
or other increases or reductions of shares of its outstanding  Common Stock, and
in the event of the  Company  being  consolidated  with or merged into any other
corporation.

                  I.        Amendment or Termination.

                           A.        The Board of Directors of the Company may 
     at any time and for any  reason  terminate  or amend  the  Plan.  Except as
provided  in  Section  18, no such  termination  can affect  options  previously
granted,  provided  that an Offering  Period may be  terminated  by the Board of
Directors on any Exercise Date if the Board  determines  that the termination of
the Plan is in the best interests of the Company and its shareholders. Except as
provided in Section 18 hereof,  no  amendment  may make any change in any option
theretofore  granted which adversely  affects the rights of any participant.  To
the extent  necessary to comply with  Section 423 of the Code (or any  successor
rule or provision or any other applicable law or regulation),  the Company shall
obtain shareholder approval in such a manner and to such a degree as required.

                           A.        Without shareholder consent and without 
     regard to whether any  participant  rights may be  considered  to have been
"adversely  affected," the Board (or its committee)  shall be entitled to change
the Offering Periods, limit the frequency and/or number of changes in the amount
withheld during an Offering  Period,  establish the exchange ratio applicable to
amounts  withheld  in  a  currency  other  than  U.S.  dollars,  permit  payroll
withholding  in excess of the amount  designated  by a  participant  in order to
adjust for delays or mistakes in the Company's  processing of properly completed
withholding  elections,  establish  reasonable  waiting and  adjustment  periods
and/or accounting and crediting procedures to ensure that amounts applied toward
the  purchase of Common  Stock for each  participant  properly  correspond  with
amounts withheld from the participant's  Compensation,  and establish such other
limitations or procedures as the Board (or its committee) determines in its sole
discretion advisable which are consistent with the Plan.

                  I.  Notices.   All  notices  or  other   communications  by  a
participant to the Company under or in connection  with the Plan shall be deemed
to have been duly given when  received in the form  specified  by the Company at
the  location,  or by the  person,  designated  by the  Company  for the receipt
thereof.

                  I.  Conditions  Upon  Issuance of Shares.  Shares shall not be
issued  with  respect to an option  unless the  exercise  of such option and the
issuance  and  delivery of such shares  pursuant  thereto  shall comply with all
applicable   provisions  of  law,  domestic  or  foreign,   including,   without
limitation,  the Securities Act of 1933, as amended, the Exchange Act, the rules
and  regulations  promulgated  thereunder,  and the  requirements  of any  stock
exchange upon which the shares may then be listed,  and shall be further subject
to the approval of counsel for the Company with respect to such compliance.

                  As a condition to the  exercise of an option,  the Company may
require the person  exercising  such option to represent and warrant at the time
of any such exercise that the shares are being purchased only for investment and
without  any  present  intention  to sell or  distribute  such shares if, in the
opinion of counsel for the Company,  such a representation is required by any of
the aforementioned applicable provisions of law.

                  I. Term of Plan.  The Plan  shall  become  effective  upon the
earlier to occur of its  adoption by the Board of  Directors  or its approval by
the  shareholders of the Company.  It shall continue in effect for a term of ten
(10) years unless sooner terminated under Section 19 hereof.

3.       I understand that said payroll  deductions shall be accumulated for the
         purchase of shares of Common  Stock at the  applicable  Purchase  Price
         determined  in  accordance  with the Employee  Stock  Purchase  Plan. I
         understand  that if I do not  withdraw  from an  Offering  Period,  any
         accumulated  payroll deductions will be used to automatically  exercise
         my option.

4.       I have received a copy of the complete  "Employee Stock Purchase Plan."
         I understand that my  participation in the Employee Stock Purchase Plan
         is in all respects  subject to the terms of the Plan. I understand that
         the  grant  of  the  option  by the  Company  under  this  Subscription
         Agreement is subject to obtaining  shareholder approval of the Employee
         Stock Purchase Plan.

5.       Shares purchased for me under the Employee Stock Purchase Plan should 
         be issued in the name(s) of (Employee or Employee and Spouse Only): .

6.       I understand that if I dispose of any shares received by me pursuant 
     to the Plan within 2 years after the Enrollment  Date (the first day of the
Offering  Period during which I purchased  such  shares),  I will be treated for
federal income tax purposes as having  received  ordinary  income at the time of
such  disposition  in an amount  equal to the excess of the fair market value of
the shares at the time such shares were  purchased  by me over the price which I
paid for the shares.  I hereby agree to notify the Company in writing  within 30
days  after  the date of any  disposition  of shares  and I will  make  adequate
provision for Federal, state or other tax withholding obligations, if any, which
arise upon the disposition of the Common Stock. The Company may, but will not be
obligated to,  withhold from my  compensation  the amount  necessary to meet any
applicable  withholding  obligation including any withholding  necessary to make
available to the Company any tax deductions or benefits  attributable to sale or
early disposition of Common Stock by me. If I dispose of such shares at any time
after the expiration of the 2-year holding  period,  I understand that I will be
treated for federal  income tax purposes as having  received  income only at the
time of such disposition,  and that such income will be taxed as ordinary income
only to the  extent of an amount  equal to the  lesser of (1) the  excess of the
fair  market  value  of the  shares  at the  time of such  disposition  over the
purchase price which I paid for the shares,  or (2) 15% of the fair market value
of the shares on the first day of the  Offering  Period.  The  remainder  of the
gain, if any, recognized on such disposition will be taxed as capital gain

7.       I hereby agree to be bound by the terms of the Employee  Stock Purchase
         Plan. The  effectiveness  of this  Subscription  Agreement is dependent
         upon my eligibility to participate in the Employee Stock Purchase Plan.

8.       In the  event of my  death,  I hereby  designate  the  following  as my
         beneficiary(ies)  to receive all  payments  and shares due me under the
         Employee Stock Purchase Plan:
