                           1997 EQUITY INCENTIVE PLAN

                          As Adopted May 15, 1997 and
                              Amended May 13, 1998


         1.   PURPOSE.  The purpose of this Plan is to provide incentives to
              -------                                                       
attract, retain and motivate eligible persons whose present and potential
contributions are important to the success of the Company, its Parent and
Subsidiaries, by offering them an opportunity to participate in the Company's
future performance through awards of Options, Restricted Stock and Stock
Bonuses.  Capitalized terms not defined in the text are defined in Section 23.

         2.   SHARES SUBJECT TO THE PLAN.
              -------------------------- 

              2.1  Number of Shares Available. Subject to Sections 2.2 and 18,
                   --------------------------            
the total number of Shares reserved and available for grant and issuance
pursuant to this Plan will be 25,175,000 Shares, less: (a) the total number of
Shares issued by the Company under (i) restricted stock purchase agreements
entered into prior to the Effective Date of this Plan with employees, officers,
directors, consultants, independent contractors or advisors of the Company and
(ii) the Company's 1996 Incentive Stock Option Plan or 1996 Incentive Stock
Option Plan No. 2 (the "PRIOR PLANS") pursuant to the exercise of options
granted on or before the Effective Date; (b) Shares that are issuable as of the
Effective Date upon exercise of options granted under the Prior Plans; and (c)
Shares issued as of any date under the Company's 1997 Employee Stock Purchase
Plan adopted contemporaneously with this Plan.

          Subject to Sections 2.2 and 18 hereof, Shares that: (a) are subject to
issuance upon exercise of an option granted under the Prior Plans or under this
Plan that cease to be subject to such option for any reason other than exercise
of such option; (b) are subject to an award granted under restricted stock
purchase agreements entered into prior to the Effective Date of this Plan with
employees, officers, directors, consultants, independent contractors or advisors
of the Company, the Prior Plans, or this Plan, that are forfeited or are
repurchased by the Company at the original issue price; or (c) are subject to
any other award granted under the Prior Plans or under this Plan that otherwise
terminates without Shares being issued, will again be available for grant and
issuance in connection with future Awards under this Plan.

          At all times the Company shall reserve and keep available a sufficient
number of Shares as shall be required to satisfy the requirements of all
outstanding Options granted under this Plan and all other outstanding but
unvested Awards granted under this Plan.

          The sum of (a) Restricted Stock Awards, (b) Stock Bonus Awards, or (c)
Options with a Purchase Price or Exercise Price, as the case may be, below Fair
Market Value issued under this Plan may not exceed 20% of the total number of
Shares reserved for grant and issuance pursuant to this Plan as of any date.

              2.2  Adjustment of Shares.  In the event that the number of
                   --------------------                                  
outstanding Shares is changed by a stock dividend, recapitalization, stock
split, reverse stock split, subdivision, combination, reclassification or
similar change in the capital structure of the Company without consideration,
then (a) the number of Shares reserved for issuance under this Plan, (b) the
Exercise Prices of and number of Shares subject to outstanding Options, and (c)
the number of Shares subject to other outstanding Awards will be proportionately
adjusted, subject to any required action by the Board or the stockholders of the
Company and compliance with applicable securities laws; provided, however, that
                                                        --------  -------      
fractions of a Share will not be issued but will either be replaced by a cash
payment equal to the Fair Market Value of such fraction of a Share or will be
rounded up to the nearest whole Share, as determined by the Committee.
<PAGE>
 
         3.   ELIGIBILITY.  ISOs (as defined in Section 5 below) may be granted
              -----------                                                      
only to employees (including officers and directors who are also employees) of
the Company or of a Parent or Subsidiary of the Company.  All other Awards may
be granted to employees, officers, directors, consultants, independent
contractors and advisors of the Company or any Parent or Subsidiary of the
Company; provided such consultants, contractors and advisors render bona fide
         --------                                                            
services not in connection with the offer and sale of securities in a capital-
raising transaction.  No person will be eligible to receive more than 1,000,000
Shares in any calendar year under this Plan pursuant to the grant of Awards
hereunder, other than new employees of the Company or of a Parent or Subsidiary
of the Company (including new employees who are also officers and directors of
the Company or any Parent or Subsidiary of the Company) who are eligible to
receive up to a maximum of 2,000,000 Shares in the calendar year in which they
commence their employment.  A person may be granted more than one Award under
this Plan.

              compensation plan of the Company or any Parent or Subsidiary of
              the Company;

         (g)  grant waivers of Plan or Award conditions;

         (h)  determine the vesting, exercisability and payment of Awards;

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

         (j)  determine whether an Award has been earned; and

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

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

         5.   OPTIONS. The Committee may grant Options to eligible persons
              -------
and will determine whether such Options will be Incentive Stock Options within
the meaning of the Code ("ISO") or Nonqualified Stock Options ("NQSOS"), the
number of Shares subject to the Option, the Exercise Price of the Option, the
period 

                                       2
<PAGE>
 
during which the Option may be exercised, and all other terms and conditions of
the Option, subject to the following:

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

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

          5.3      Exercise Period.  Options may be exercisable within the times
                   ---------------                                              
or upon the events determined by the Committee as set forth in the Stock Option
Agreement governing such Option; provided, however, that no Option will be
                                 --------  -------                        
exercisable after the expiration of ten (10) years from the date the Option is
granted; and provided further that no ISO granted to a person who directly or by
             ----------------                                                   
attribution owns more than ten percent (10%) of the total combined voting power
of all classes of stock of the Company or of any Parent or Subsidiary of the
Company ("TEN PERCENT STOCKHOLDER") will be exercisable after the expiration of
five (5) years from the date the ISO is granted.  The Committee also may provide
for Options to become exercisable at one time or from time to time, periodically
or otherwise, in such number of Shares or percentage of Shares as the Committee
determines.

          5.4      Exercise Price.  The Exercise Price of an Option will be
                   --------------                                          
determined by the Committee when the Option is granted and may be not less than
85% of the Fair Market Value of the Shares on the date of grant; provided that:
(i) the Exercise Price of an ISO will be not less than 100% of the Fair Market
Value of the Shares on the date of grant; and (ii) the Exercise Price of any ISO
granted to a Ten Percent Stockholder will not be less than 110% of the Fair
Market Value of the Shares on the date of grant.  Payment for the Shares
purchased may be made in accordance with Section 8 of this Plan.

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

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

         (a)  If the Participant is Terminated for any reason except death or
              Disability, then the Participant may exercise such Participant's
              Options only to the extent that such Options would have been
              exercisable upon the Termination Date no later than three (3)
              months after the Termination Date (or such shorter or longer time
              period not exceeding five (5) years as may be determined by the
              Committee, with any exercise beyond three (3) months after the
              Termination Date deemed to be an NQSO), but in any event, no later
              than the expiration date of the Options.

         (b)  If the Participant is Terminated because of Participant's death or
              Disability (or the Participant dies within three (3) months after
              a Termination other than because of Participant's death or
              disability), then Participant's Options may be exercised only to
              the extent that such Options would have been exercisable by
              Participant on the Termination Date and must be exercised by
              Participant (or Participant's legal representative or 

                                       3
<PAGE>
 
              authorized assignee) no later than twelve (12) months after the
              Termination Date (or such shorter or longer time period not
              exceeding five (5) years as may be determined by the Committee,
              with any such exercise beyond (a) three (3) months after the
              Termination Date when the Termination is for any reason other than
              the Participant's death or Disability, or (b) twelve (12) months
              after the Termination Date when the Termination is for
              Participant's death or Disability, deemed to be an NQSO), but in
              any event no later than the expiration date of the Options.

         (c)  If a Participant is terminated for Cause, then the Participant may
              exercise such Participant Options only to the extent that such
              Options would have been exercisable upon the Termination Date no
              later than one (1) month after the Termination Date (or such
              shorter period as may be determined by the Committee), but in any
              event, no later than the expiration date of the Options.  In
              making such determination, the Board shall give the Participant an
              opportunity to present to the Board evidence on his behalf.  For
              the purpose of this paragraph, termination of service shall be
              deemed to occur on the date when the Company dispatches notice or
              advice to the Participant that his service is terminated.

              5.7      Limitations on Exercise.  The Committee may specify a
                       -----------------------                              
reasonable minimum number of Shares that may be purchased on any exercise of an
Option, provided that such minimum number will not prevent Participant from
exercising the Option for the full number of Shares for which it is then
exercisable.

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

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

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

         6.   RESTRICTED STOCK.  A Restricted Stock Award is an offer by the
              ----------------                                              
Company to sell to an eligible person Shares that are subject to restrictions.
The Committee will determine to whom an offer will be made, the number of Shares
the person may purchase, the price to be paid (the "PURCHASE PRICE"), the
restrictions to which the Shares will be subject, and all other terms and
conditions of the Restricted Stock Award, subject to the following:

              6.1      Form of Restricted Stock Award.  All purchases under a
                       ------------------------------                        
Restricted Stock Award made pursuant to this Plan will be evidenced by an Award
Agreement ("RESTRICTED STOCK PURCHASE AGREEMENT") that will be in such form
(which need not be the same for each Participant) as the Committee will from
time to time 

                                       4
<PAGE>
 
approve, and will comply with and be subject to the terms and conditions of this
Plan. The offer of Restricted Stock will be accepted by the Participant's
execution and delivery of the Restricted Stock Purchase Agreement and full
payment for the Shares to the Company within thirty (30) days from the date the
Restricted Stock Purchase Agreement is delivered to the person. If such person
does not execute and deliver the Restricted Stock Purchase Agreement along with
full payment for the Shares to the Company within thirty (30) days, then the
offer will terminate, unless otherwise determined by the Committee.

          6.2      Purchase Price.  The Purchase Price of Shares sold pursuant
                   --------------                                             
to a Restricted Stock Award will be determined by the Committee on the date the
Restricted Stock Award is granted, except in the case of a sale to a Ten Percent
Stockholder, in which case the Purchase Price will be 100% of the Fair Market
Value.  Payment of the Purchase Price may be made in accordance with Section 8
of this Plan.

          6.3      Terms of Restricted Stock Awards.  Restricted Stock Awards
                   --------------------------------                          
shall be subject to such restrictions as the Committee may impose.  These
restrictions may be based upon completion of a specified number of years of
service with the Company or upon completion of the performance goals as set out
in advance in the Participant's individual Restricted Stock Purchase Agreement.
Restricted Stock Awards may vary from Participant to Participant and between
groups of Participants.  Prior to the grant of a Restricted Stock Award, the
Committee shall:  (a) determine the nature, length and starting date of any
Performance Period for the Restricted Stock Award; (b) select from among the
Performance Factors to be used to measure performance goals, if any; and (c)
determine the number of Shares that may be awarded to the Participant.  Prior to
the payment of any Restricted Stock Award, the Committee shall determine the
extent to which such Restricted Stock Award has been earned.  Performance
Periods may overlap and Participants may participate simultaneously with respect
to Restricted Stock Awards that are subject to different Performance Periods and
having different performance goals and other criteria.

          6.4      Termination During Performance Period.  If a Participant is
                   -------------------------------------                      
Terminated during a Performance Period for any reason, then such Participant
will be entitled to payment (whether in Shares, cash or otherwise) with respect
to the Restricted Stock Award only to the extent earned as of the date of
Termination in accordance with the Restricted Stock Purchase Agreement, unless
the Committee will determine otherwise.

         7.   STOCK BONUSES.
              ------------- 

          7.1      Awards of Stock Bonuses. A Stock Bonus is an award of Shares
                   -----------------------
(which may consist of Restricted Stock) for services rendered to the Company or
any Parent or Subsidiary of the Company. A Stock Bonus may be awarded for past
services already rendered to the Company, or any Parent or Subsidiary of the
Company pursuant to an Award Agreement (the "STOCK BONUS AGREEMENT") that will
be in such form (which need not be the same for each Participant) as the
Committee will from time to time approve, and will comply with and be subject to
the terms and conditions of this Plan. A Stock Bonus may be awarded upon
satisfaction of such performance goals as are set out in advance in the
Participant's individual Award Agreement (the "PERFORMANCE STOCK BONUS
AGREEMENT") that will be in such form (which need not be the same for each
Participant) as the Committee will from time to time approve, and will comply
with and be subject to the terms and conditions of this Plan. Stock Bonuses may
vary from Participant to Participant and between groups of Participants, and may
be based upon the achievement of the Company, Parent or Subsidiary and/or
individual performance factors or upon such other criteria as the Committee may
determine.

          7.2      Terms of Stock Bonuses.  The Committee will determine the
                   ----------------------                                   
number of Shares to be awarded to the Participant.  If the Stock Bonus is being
earned upon the satisfaction of performance goals pursuant to a Performance
Stock Bonus Agreement, then the Committee will: (a)  determine the nature,
length and starting date of any Performance Period for each Stock Bonus; (b)
select from among the Performance Factors to be used to measure the performance,
if any; and (c) determine the number of Shares that may be awarded to the
Participant.  Prior to the payment of any Stock Bonus, the Committee shall
determine the extent to which such Stock Bonuses have been earned.  Performance
Periods may overlap and Participants may participate simultaneously with respect
to Stock Bonuses that are subject to different Performance Periods and different
performance goals and other criteria.  The number of Shares may be fixed or may
vary in accordance with such performance goals and criteria as may be determined
by the Committee.  The Committee may adjust the performance goals applicable to
the Stock Bonuses to take into account changes in law and accounting or tax
rules and to make such adjustments as 

                                       5
<PAGE>
 
the Committee deems necessary or appropriate to reflect the impact of
extraordinary or unusual items, events or circumstances to avoid windfalls or
hardships.

               7.3       Form of Payment. The earned portion of a Stock Bonus
                         ---------------
may be paid currently or on a deferred basis with such interest or dividend
equivalent, if any, as the Committee may determine. Payment may be made in the
form of cash or whole Shares or a combination thereof, either in a lump sum
payment or in installments, all as the Committee will determine.

          8.   PAYMENT FOR SHARE PURCHASES.
               --------------------------- 

               8.1       Payment. Payment for Shares purchased pursuant to this
                         -------
Plan may be made in cash (by check) or, where expressly approved for the
Participant by the Committee and where permitted by law:

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

          (c)  by tender of a full recourse promissory note having such terms as
               may be approved by the Committee and bearing interest at a rate
               sufficient to avoid imputation of income under Sections 483 and
               1274 of the Code; provided, however, that Participants who are
                                 --------  -------                  
               not employees or directors of the Company will not be entitled to
               purchase Shares with a promissory note unless the note is
               adequately secured by collateral other than the Shares;

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

          (e)  with respect only to purchases upon exercise of an Option, and
               provided that a public market for the Company's stock exists:

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

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

          (f)  by any combination of the foregoing.

                8.2      Loan Guarantees. The Committee may help the Participant
                         ---------------
pay for Shares purchased under this Plan by authorizing a guarantee by the
Company of a third-party loan to the Participant.

           9.   WITHHOLDING TAXES.
                ----------------- 

                9.1      Withholding Generally. Whenever Shares are to be issued
                         ---------------------
in satisfaction of Awards granted under this Plan, the Company may require the
Participant to remit to the Company an amount 

                                       6
<PAGE>
 
sufficient to satisfy federal, state and local withholding tax requirements
prior to the delivery of any certificate or certificates for such Shares.
Whenever, under this Plan, payments in satisfaction of Awards are to be made in
cash, such payment will be net of an amount sufficient to satisfy federal,
state, and local withholding tax requirements.

              9.2      Stock Withholding.  When, under applicable tax laws, a
                       -----------------                                     
Participant incurs tax liability in connection with the exercise or vesting of
any Award that is subject to tax withholding and the Participant is obligated to
pay the Company the amount required to be withheld, the Committee may in its
sole discretion allow the Participant to satisfy the minimum withholding tax
obligation by electing to have the Company withhold from the Shares to be issued
that number of Shares having a Fair Market Value equal to the minimum amount
required to be withheld, determined on the date that the amount of tax to be
withheld is to be determined.  All elections by a Participant to have Shares
withheld for this purpose will be made in accordance with the requirements
established by the Committee and be in writing in a form acceptable to the
Committee.


         10.  PRIVILEGES OF STOCK OWNERSHIP.
              ----------------------------- 

              10.1      Voting and Dividends. No Participant will have any of
                        --------------------
the rights of a stockholder with respect to any Shares until the Shares are
issued to the Participant. After Shares are issued to the Participant, the
Participant will be a stockholder and have all the rights of a stockholder with
respect to such Shares, including the right to vote and receive all dividends or
other distributions made or paid with respect to such Shares; provided, that if
                                                              -------- 
such Shares are Restricted Stock, then any new, additional or different
securities the Participant may become entitled to receive with respect to such
Shares by virtue of a stock dividend, stock split or any other change in the

Price pursuant to Section 12.

              10.2      Financial Statements. The Company will provide financial

right to repurchase a portion of or all Unvested Shares held by a Participant
following such Participant's Termination at any time within ninety (90) days
after the later of Participant's Termination Date and the date Participant
purchases Shares under this Plan, for cash and/or cancellation of purchase money
indebtedness, at the Participant's Exercise Price or Purchase Price, as the case
may be.

         13.  CERTIFICATES.  All certificates for Shares or other securities
              ------------

and other restrictions as the Committee may deem necessary or advisable,
including restrictions under any applicable federal, state or foreign securities
law, or any rules, regulations and other requirements of the SEC or any stock
exchange or automated quotation system upon which the Shares may be listed or
quoted.

         14.  ESCROW; PLEDGE OF SHARES.  To enforce any restrictions on a
              ------------------------                                   
Participant's Shares, the Committee may require the Participant to deposit all
certificates representing Shares, together with stock

<PAGE>
 
powers or other instruments of transfer approved by the Committee, appropriately
endorsed in blank, with the Company or an agent designated by the Company to
hold in escrow until such restrictions have lapsed or terminated, and the
Committee may cause a legend or legends referencing such restrictions to be
placed on the certificates. Any Participant who is permitted to execute a
promissory note as partial or full consideration for the purchase of Shares
under this Plan will be required to pledge and deposit with the Company all or
part of the Shares so purchased as collateral to secure the payment of
Participant's obligation to the Company under the promissory note; provided,
                                                                   --------
however, that the Committee may require or accept other or additional forms of
- -------
collateral to secure the payment of such obligation and, in any event, the
Company will have full recourse against the Participant under the promissory
note notwithstanding any pledge of the Participant's Shares or other collateral.
In connection with any pledge of the Shares, Participant will be required to
execute and deliver a written pledge agreement in such form as the Committee
will from time to time approve. The Shares purchased with the promissory note
may be released from the pledge on a pro rata basis as the promissory note is
paid.

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

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

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

         18.  CORPORATE TRANSACTIONS.
              ---------------------- 

              18.1   Assumption or Replacement of Awards by Successor. In the
                     ------------------------------------------------  
event of (a) a dissolution or liquidation of the Company, (b) a merger or
consolidation in which the Company is not the surviving corporation (other than
a merger or consolidation with a wholly-owned subsidiary, a reincorporation of
the Company in a different jurisdiction, or other transaction in which there is
no substantial change in the stockholders of the Company or their relative stock
holdings and the Awards granted under this Plan are assumed, converted or
replaced by the successor corporation, which assumption will be binding on all
Participants), (c) a merger in which the Company is the surviving corporation
but after which the stockholders of the Company immediately prior to such merger
(other than any stockholder that merges, or which owns or controls another
corporation that merges, with the Company in such merger) cease to own their
shares or other equity interest in the Company, (d) the sale of substantially
all of the assets of the Company, or (e) the acquisition, sale, or transfer of
more than 50% of the outstanding shares of the Company by tender offer or
similar transaction, any or all outstanding Awards may be assumed, converted or
replaced by the successor corporation (if any), which assumption, conversion or
replacement will be binding on all Participants. In the alternative, the
successor corporation may substitute equivalent Awards or provide substantially
similar consideration to Participants as was provided to stockholders (after
taking into account the existing provisions of the Awards). The successor
corporation may also issue, in place of outstanding Shares of 

                                       8
<PAGE>
 
the Company held by the Participant, substantially similar shares or other
property subject to repurchase restrictions no less favorable to the
Participant. In the event such successor corporation (if any) refuses to assume
or substitute Awards, as provided above, pursuant to a transaction described in
this Subsection 18.1, the vesting of all Awards will accelerate and the Options
will become exercisable in full prior to the consummation of such event at such
times and on such conditions as the Committee determines, and if such Options
are not exercised prior to the consummation of the corporate transaction, they
shall terminate in accordance with the provisions of this Plan.

          18.2      Other Treatment of Awards.  Subject to any greater rights
                    -------------------------                                
granted to Participants under the foregoing provisions of this Section 18, in
the event of the occurrence of any transaction described in Section 18.1, any
outstanding Awards will be treated as provided in the applicable agreement or
plan of merger, consolidation, dissolution, liquidation, or sale of assets.

          18.3      Assumption of Awards by the Company.  The Company, from time
                    -----------------------------------                         
to time, also may substitute or assume outstanding awards granted by another
company, whether in connection with an acquisition of such other company or
otherwise, by either; (a) granting an Award under this Plan in substitution of
such other company's award; or (b) assuming such award as if it had been granted
under this Plan if the terms of such assumed award could be applied to an Award
granted under this Plan.  Such substitution or assumption will be permissible if
the holder of the substituted or assumed award would have been eligible to be
granted an Award under this Plan if the other company had applied the rules of
this Plan to such grant.  In the event the Company assumes an award granted by
another company, the terms and conditions of such award will remain unchanged
(except that the exercise price and the number and nature of Shares issuable
- -------                                                                     
upon exercise of any such option will be adjusted appropriately pursuant to
Section 424(a) of the Code).  In the event the Company elects to grant a new
Option rather than assuming an existing option, such new Option may be granted
with a similarly adjusted Exercise Price.

         19.  ADOPTION AND STOCKHOLDER APPROVAL.  This Plan will become
              ---------------------------------                        
effective on the date on which the registration statement filed by the Company
with the SEC under the Securities Act registering the initial public offering of
the Company's Series A Common Stock is declared effective by the SEC (the
"EFFECTIVE DATE").  This Plan shall be approved by the stockholders of the
Company (excluding Shares issued pursuant to this Plan), consistent with
applicable laws, within twelve (12) months before or after the date this Plan is
adopted by the Board.  Upon the Effective Date, the Committee may grant Awards
pursuant to this Plan; provided, however, that: (a) no Option may be exercised
                       --------  -------                                      
prior to initial stockholder approval of this Plan; (b) no Option granted
pursuant to an increase in the number of Shares subject to this Plan approved by
the Board will be exercised prior to the time such increase has been approved by
the stockholders of the Company; and (c) in the event that stockholder approval
of such increase is not obtained within the time period provided herein, all
Awards granted hereunder will be canceled, any Shares issued pursuant to any
Award will be canceled, and any purchase of Shares hereunder will be rescinded.

         20.  TERM OF PLAN/GOVERNING LAW.  Unless earlier terminated as provided
              --------------------------                                        
herein, this Plan will terminate ten (10) years from the date this Plan is
adopted by the Board or, if earlier, the date of stockholder approval.  This
Plan and all agreements thereunder shall be governed by and construed in
accordance with the laws of the State of California.

         21.  AMENDMENT OR TERMINATION OF PLAN.  The Board may at any time
              --------------------------------                            
terminate or amend this Plan in any respect, including without limitation
amendment of any form of Award Agreement or instrument to be executed pursuant
to this Plan; provided, however, that the Board will not, without the approval
              --------  -------                                               
of the stockholders of the Company, amend this Plan in any manner that requires
such stockholder approval.

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

                             Amended May 13, 1998

grant options for purchase of the Company's Series A Common Stock to eligible
employees of the Company and its Participating Subsidiaries (as hereinafter
defined) pursuant to this Employee Stock Purchase Plan (this "PLAN").  For
purposes of this Plan, "PARENT CORPORATION" and "SUBSIDIARY" (collectively,
"PARTICIPATING SUBSIDIARIES") shall have the same meanings as "parent
corporation" and "subsidiary corporation" in Sections 424(e) and 424(f),
respectively, of the Internal Revenue Code of 1986, as amended (the "CODE").
"PARTICIPATING SUBSIDIARIES" are Parent Corporations or Subsidiaries that the
Board of Directors of the Company (the "BOARD") designates from time to time as
corporations that shall participate in this Plan.  The Company intends this Plan
to qualify as an "employee stock purchase plan" under Section 423 of the Code
(including any amendments to or replacements of such Section), and this Plan
shall be so construed.  Any term not expressly defined in this Plan but defined
for purposes of Section 423 of the Code shall have the same definition herein.
A total of 1,000,000 shares of the Company's Series A Common Stock is reserved
for issuance under this Plan.  Such number shall be subject to adjustments
effected in accordance with Section 14 of this Plan.

     2.  PURPOSE.  The purpose of this Plan is to provide eligible employees of
the Company and Participating Subsidiaries with a convenient means of acquiring
an equity interest in the Company through payroll deductions, to enhance such
employees' sense of participation in the affairs of the Company and
Participating Subsidiaries, and to provide an incentive for continued
employment.

     3.  ADMINISTRATION.  This Plan shall be administered by the Compensation
Committee of the Board (the "COMMITTEE").  Subject to the provisions of this
Plan and the limitations of Section 423 of the Code or any successor provision
in the Code, all questions of interpretation or application of this Plan shall
be determined by the Committee and its decisions shall be final and binding upon
all participants.  Members of the Committee shall receive no compensation for
their services in connection with the administration of this Plan, other than
standard fees as established from time to time by the Board for services
rendered by Board members serving on Board committees.  All expenses incurred in
connection with the administration of this Plan shall be paid by the Company.

     4.  ELIGIBILITY.  Any employee of the Company or the Participating
Subsidiaries is eligible to participate in an Offering Period (as hereinafter
defined) under this Plan except the following:

       (a)  employees who are not employed by the Company or Participating
Subsidiaries fifteen (15) days before the beginning of such Offering Period,
except that employees who are employed on the effective date of the registration
statement filed by the Company with the Securities and Exchange Commission
("SEC") under the Securities Act of 1933, as amended (the "SECURITIES ACT")

       (b)  employees who are customarily employed for twenty (20) hours or less
per week;

       (c)  employees who are customarily employed for five (5) months or less
in a calendar year;

       (d)  employees who, together with any other person whose stock would be
attributed to such employee pursuant to Section 424(d) of the Code, own stock or
hold options to purchase stock possessing five percent (5%) or more of the total
combined voting power or value of all classes of stock of the Company or any of

<PAGE>
 
own stock or hold options to purchase stock possessing five percent (5%) or more
of the total combined voting power or value of all classes of stock of the
Company or any of its Participating Subsidiaries; and

       (e)  individuals who provide services to the Company or any of its
Participating Subsidiaries as independent contractors whether or not
reclassified as common law employees, unless the Company or a Participating
Subsidiary withholds or is required to withhold U.S. Federal employment taxes
for such individuals pursuant to Section 3402 of the Code.

     5.  OFFERING DATES.  The offering periods of this Plan (each, an "OFFERING
PERIOD") shall be of twenty-four (24) months duration commencing on February 15
and August 15 of each year and ending on August 14 and February 14 of each year;
provided, however, that notwithstanding the foregoing, the first such Offering
- -----------------                                               
Period shall commence on the first business day on which price quotations for
the Company's Series A Common Stock are available on the Nasdaq National Market
(the "FIRST OFFERING DATE") and shall end on August 14, 1999. Except for the
first Offering Period, each Offering Period shall consist of four (4) six-month
purchase periods (individually, a "PURCHASE PERIOD") during which payroll
deductions of the participants are accumulated under this Plan. The first
Offering Period shall consist of no fewer than three Purchase Periods, any of
which may be greater or less than six months as determined by the Committee. The
first business day of each Offering Period is referred to as the "OFFERING
DATE". The last business day of each Purchase Period is referred to as the
"PURCHASE DATE". The Committee shall have the power to change the duration of
Offering Periods or Purchase Periods with respect to offerings without
stockholder approval if such change is announced at least fifteen (15) days
prior to the scheduled beginning of the first Offering Period or Purchase Period
to be affected.

     6.  PARTICIPATION IN THIS PLAN.  Eligible employees may become participants
in an Offering Period under this Plan on the first Offering Date after
satisfying the eligibility requirements by delivering a subscription agreement
to the Company's treasury department (the "TREASURY DEPARTMENT") not later than
fifteen (15) days before such Offering Date unless a later time for filing the
subscription agreement authorizing payroll deductions is set by the Committee
for all eligible employees with respect to a given Offering Period.  An eligible
employee who does not deliver a subscription agreement to the Treasury
Department by such date after becoming eligible to participate in such Offering
Period shall not participate in that Offering Period or any subsequent Offering
Period unless such employee enrolls in this Plan by filing a subscription
agreement with the Treasury Department not later than fifteen (15) days
preceding a subsequent Offering Date.  Once an employee becomes a participant in
an Offering Period, such employee will automatically participate in the Offering
Period commencing immediately following the last day of the prior Offering
Period unless the employee withdraws or is deemed to withdraw from this Plan or
terminates further participation in the Offering Period as set forth in Section
11 below.  Such participant is not required to file any additional subscription
agreement in order to continue participation in this Plan.

     7.  GRANT OF OPTION ON ENROLLMENT.  Enrollment by an eligible employee in
this Plan with respect to an Offering Period will constitute the grant (as of
the Offering Date) by the Company to such employee of an option to purchase on
the Purchase Date up to that number of shares of Series A Common Stock of the
Company determined by dividing (a) the amount accumulated in such employee's
payroll deduction account during such Purchase Period by (b) the lower of (i)
eighty-five percent (85%) of the fair market value of a share of the Company's
Series A Common Stock on the Offering Date (but in no event less than the par
value of a share of the Company's Series A Common Stock), or (ii) eighty-five
percent (85%) of the fair market value of a share of the Company's Series A
Common Stock on the Purchase Date (but in no event less than the par value of a
share of the Company's Series A Common Stock), provided, however, that the
                                               -----------------          
number of shares of the Company's Series A Common Stock subject to any option
granted pursuant to this Plan shall not exceed the lesser of (a) the maximum
number of shares set by the Committee pursuant to Section 10(c) below with
respect to the applicable Purchase Date, or (b) the maximum number of shares
which may be purchased pursuant to Section 10(b) below with respect to the
applicable Purchase Date.  The fair market value of a share of the Company's
Series A Common Stock shall be determined as provided in Section 8 hereof.

     8.  PURCHASE PRICE.  The purchase price per share at which a share of
Series A Common Stock will be sold in any Offering Period shall be eighty-five
percent (85%) of the lesser of:

                                       2
<PAGE>
 
       (a)  The fair market value on the Offering Date; or

       (b)  The fair market value on the Purchase Date.

       For purposes of this Plan, the term "FAIR MARKET VALUE" means, as of any
date, the value of a share of the Company's Series A Common Stock determined as
follows:

         (a)  if such Series A Common Stock is then quoted on the Nasdaq
              National Market, its closing price on the Nasdaq National Market
              on the date of determination as reported in The Wall Street
                                                          ---------------
              Journal;
              ------- 

         (b)  if such Series A Common Stock is publicly traded and is then
              listed on a national securities exchange, its closing price on the
              date of determination on the principal national securities
              exchange on which the Series A Common Stock is listed or admitted
              to trading as reported in The Wall Street Journal;
                                        ----------------------- 

         (c)  if such Series A Common Stock is publicly traded but is not quoted
              on the Nasdaq National Market nor listed or admitted to trading on
              a national securities exchange, the average of the closing bid and
              asked prices on the date of determination as reported in The Wall
                                                                       --------
              Street Journal; or
              --------------    

         (d)  if none of the foregoing is applicable, by the Board in good
              faith, which in the case of the First Offering Date will be the
              price per share at which shares of the Company's Series A Common
              Stock are initially offered for sale to the public by the
              Company's underwriters in the initial public offering of the
              Company's Series A Common Stock pursuant to a registration
              statement filed with the SEC under the Securities Act.

     9.  PAYMENT OF PURCHASE PRICE; CHANGES IN PAYROLL DEDUCTIONS; ISSUANCE OF
SHARES.

       (a)  The purchase price of the shares is accumulated by regular payroll
deductions made during each Offering Period.  The deductions are made as a
percentage of the participant's compensation in one percent (1%) increments not
less than two percent (2%), nor greater than ten percent (10%) or such lower
limit set by the Committee.  Compensation shall mean base salary, commissions,
bonuses, and shift premiums not to exceed  $250,000 per calendar year, provided
however, that for purposes of determining a participant's compensation, any
election by such participant to reduce his or her regular cash remuneration
under Sections 125 or 401(k) of the Code shall be treated as if the participant
did not make such election.  Except for the first Offering Period, payroll
deductions shall commence on the first payday of the Offering Period and shall
continue to the end of the Offering Period unless sooner altered or terminated
as provided in this Plan.  Payroll deductions for the first Offering Period
shall commence at the end of the first full pay period following the First
Offering Date.

       (b)  A participant may lower (but not increase) the rate of payroll
deductions during an Offering Period by filing with the Treasury Department a
new authorization for payroll deductions, in which case the new rate shall
become effective for the next payroll period commencing more than fifteen (15)
days after the Treasury Department's receipt of the authorization and shall
continue for the remainder of the Offering Period unless changed as described
below.  Such change in the rate of payroll deductions may be made at any time
during an Offering Period, but not more than one (1) change may be made
effective during any Offering Period.  A participant may increase or decrease
the rate of payroll deductions for any subsequent Offering Period by filing with
the Treasury Department a new authorization for payroll deductions not later
than fifteen (15) days before the beginning of such Offering Period.

       (c)  All payroll deductions made for a participant are credited to his or
her account under this Plan and are deposited with the general funds of the
Company.  No interest accrues on the payroll deductions.  All payroll deductions
received or held by the Company may be used by the Company for any corporate
purpose, and the Company shall not be obligated to segregate such payroll
deductions.

       (d)  On each Purchase Date, so long as this Plan remains in effect and
provided that the participant has not submitted a signed and completed
withdrawal form before that date which notifies the Company that the participant

                                       3
<PAGE>
 
wishes to withdraw from that Offering Period under this Plan and have all
payroll deductions accumulated in the account maintained on behalf of the
participant as of that date returned to the participant, the Company shall apply
the funds then in the participant's account to the purchase of whole shares of
Series A Common Stock reserved under the option granted to such participant with
respect to the Offering Period to the extent that such option is exercisable on
the Purchase Date.  The purchase price per share shall be as specified in
Section 8 of this Plan.  Any cash remaining in a participant's account after
such purchase of shares shall be refunded to such participant in cash, without
interest; provided, however that any amount remaining in such participant's
account on a Purchase Date which is less than the amount necessary to purchase a
full share of Series A Common Stock of the Company shall be carried forward,
without interest, into the next Purchase Period or Offering Period, as the case
may be.  In the event that this Plan has been oversubscribed, all funds not used
to purchase shares on the Purchase Date shall be returned to the participant,
without interest.  No Series A Common Stock shall be purchased on a Purchase
Date on behalf of any employee whose participation in this Plan has terminated
prior to such Purchase Date.

       (e)  As promptly as practicable after the Purchase Date, the Company
shall issue shares for the participant's benefit representing the shares
purchased upon exercise of his or her option.

       (f)  During a participant's lifetime, such participant's option to
purchase shares hereunder is exercisable only by him or her.  The participant
will have no interest or voting right in shares covered by his or her option
until such option has been exercised.

     10.  LIMITATIONS ON SHARES TO BE PURCHASED.

       (a)  No participant shall be entitled to purchase stock under this Plan
at a rate which, when aggregated with his or her rights to purchase stock under
all other employee stock purchase plans of the Company or any Subsidiary,
exceeds $25,000 in fair market value, determined as of the Offering Date (or
such other limit as may be imposed by the Code) for each calendar year in which
the employee participates in this Plan.

       (b)  No more than two hundred percent (200%) of the number of shares
determined by using eighty-five percent (85%) of the fair market value of a
share of the Company's Series A Common Stock on the Offering Date as the
denominator may be purchased by a participant on any single Purchase Date.

       (c)  No participant shall be entitled to purchase more than the Maximum
Share Amount (as defined below) on any single Purchase Date.  Not less than
thirty (30) days prior to the commencement of any Offering Period, the Committee
may, in its sole discretion, set a maximum number of shares which may be
purchased by any employee at any single Purchase Date (hereinafter the "MAXIMUM
SHARE AMOUNT").  Until otherwise determined by the Committee, there shall be no
Maximum Share Amount.  In no event shall the Maximum Share Amount exceed the
amounts permitted under Section 10(b) above.  If a new Maximum Share Amount is
set, then all participants must be notified of such Maximum Share Amount prior
to the commencement of the next Offering Period.  Once the Maximum Share Amount
is set, it shall continue to apply with respect to all succeeding Purchase Dates
and Offering Periods unless revised by the Committee as set forth above.

       (d)  If the number of shares to be purchased on a Purchase Date by all
employees participating in this Plan exceeds the number of shares then available
for issuance under this Plan, then the Company will make a pro rata allocation
of the remaining shares in as uniform a manner as shall be reasonably
practicable and as the Committee shall determine to be equitable.  In such
event, the Company shall give written notice of such reduction of the number of
shares to be purchased under a participant's option to each participant affected
thereby.

       (e)  Any payroll deductions accumulated in a participant's account which
are not used to purchase stock due to the limitations in this Section 10 shall
be returned to the participant as soon as practicable after the end of the
applicable Purchase Period, without interest.

     11.  WITHDRAWAL.

       (a)  Each participant may withdraw from an Offering Period under this
Plan by signing and delivering to the Treasury Department a written notice to
that effect on a form provided for such purpose.  Such withdrawal may be elected
at any time at least fifteen (15) days prior to the end of an Offering Period.

                                       4
<PAGE>
 
       (b)  Upon withdrawal from this Plan, the accumulated payroll deductions
shall be returned to the withdrawn participant, without interest, and his or her
interest in this Plan shall terminate.  In the event a participant voluntarily
elects to withdraw from this Plan, he or she may not resume his or her
participation in this Plan during the same Offering Period, but he or she may
participate in any Offering Period under this Plan which commences on a date
subsequent to such withdrawal by filing a new authorization for payroll
deductions in the same manner as set forth above for initial participation in
this Plan.

       (c)  If the purchase price on the first day of any current Offering
Period in which a participant is enrolled is higher than the purchase price on
the first day of any subsequent Offering Period, the Company will automatically
enroll such participant in the subsequent Offering Period.  Any funds
accumulated in a participant's account prior to the first day of such subsequent
Offering Period will be applied to the purchase of shares on the Purchase Date
immediately prior to the first day of such subsequent Offering Period.  A
participant does not need to file any forms with the Company to automatically be
enrolled in the subsequent Offering Period

     12.  TERMINATION OF EMPLOYMENT.  Termination of a participant's employment
for any reason, including retirement, death or the failure of a participant to
remain an eligible employee of the Company or of a Participating Subsidiary,
immediately terminates his or her participation in this Plan.  In such event,
the payroll deductions credited to the participant's account will be returned to
him or her or, in the case of his or her death, to his or her legal
representative, without interest.  For purposes of this Section 12, an employee
will not be deemed to have terminated employment or failed to remain in the
continuous employ of the Company or of a Participating Subsidiary in the case of
sick leave, military leave, or any other leave of absence approved by the Board;
provided that such leave is for a period of not more than ninety (90) days or
- --------                                                                     
reemployment upon the expiration of such leave is guaranteed by contract or
statute.

     13.  RETURN OF PAYROLL DEDUCTIONS.  In the event a participant's interest
in this Plan is terminated by withdrawal, termination of employment or
otherwise, or in the event this Plan is terminated by the Board, the Company
shall promptly deliver to the participant all payroll deductions credited to
such participant's account.  No interest shall accrue on the payroll deductions
of a participant in this Plan.

     14.  CAPITAL CHANGES.  Subject to any required action by the stockholders
of the Company, the number of shares of Series A Common Stock covered by each
option under this Plan which has not yet been exercised and the number of shares
of Series A Common Stock which have been authorized for issuance under this Plan
but have not yet been placed under option (collectively, the "RESERVES"), as
well as the price per share of Series A Common Stock covered by each option
under this Plan which has not yet been exercised, shall be proportionately
adjusted for any increase or decrease in the number of issued and outstanding
shares of Series A Common Stock of the Company resulting from a stock split or
the payment of a stock dividend (but only on the Series A Common Stock) or any
other increase or decrease in the number of issued and outstanding shares of
Common Stock effected without receipt of any 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 Committee, whose determination 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 Series A Common
Stock subject to an option.

    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 Committee.  The Committee may,
in the exercise of its sole discretion in such instances, declare that the
options under this Plan shall terminate as of a date fixed by the Committee and
give each participant the right to exercise his or her option as to all of the
optioned stock, including shares which would not otherwise be exercisable.  In
the event of (i) a merger or consolidation in which the Company is not the
surviving corporation (other than a merger or consolidation with a wholly-owned
subsidiary, a reincorporation of the Company in a different jurisdiction, or
other transaction in which there is no substantial change in the stockholders of
the Company or their relative stock holdings and the options under this Plan are
assumed, converted or replaced by the successor corporation, which assumption
will be binding on all participants), (ii) a merger in which the Company is the
surviving corporation but after which the stockholders of the Company
immediately prior to such merger (other than any stockholder that merges, or
which owns or controls another 

                                       5
<PAGE>
 
corporation that merges, with the Company in such merger) cease to own their
shares or other equity interest in the Company, (iii) the sale of substantially
all of the assets of the Company or (iv) the acquisition, sale, or transfer of
more than 50% of the outstanding shares of the Company by tender offer or
similar transaction, each option under this Plan may be assumed or an equivalent
option may be substituted by such successor corporation or a parent or
subsidiary of such successor corporation. In the event such surviving
corporation refuses to assume or substitute options under this Plan, (i) this
Plan will terminate upon the consummation of such transaction, unless otherwise
provided by the Committee and (ii) the Committee may declare that the options
under this Plan shall terminate as of a date fixed by the Committee and give
each participant the right to exercise his or her option as to all of the
optioned stock. If the Committee makes an option fully exercisable in the event
of a merger, consolidation or sale of assets, the Committee shall notify the
participant that the option shall be fully exercisable for a certain period, and
the option and this Plan will terminate upon the expiration of such period.

    The Committee 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 Series A Common Stock covered by each outstanding option, in the
event that the Company effects one or more reorganizations, recapitalizations,
rights offerings or other increases or reductions of shares of its outstanding
Series A Common Stock, or in the event of the Company being consolidated with or
merged into any other corporation.

     15.  NONASSIGNABILITY.  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 this 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 22 hereof) by the participant.  Any such
attempt at assignment, transfer, pledge or other disposition shall be void and
without effect.

     16.  REPORTS.  Individual accounts will be maintained for each participant
in this Plan.  Each participant shall receive promptly after the end of each
Purchase Period a report of his or her account setting forth the total payroll
deductions accumulated, the number of shares purchased, the per share price
thereof and the remaining cash balance, if any, carried forward to the next
Purchase Period or Offering Period, as the case may be.

     17.  NOTICE OF DISPOSITION.  Each participant shall notify the Company if
the participant disposes of any of the shares purchased in any Offering Period
pursuant to this Plan if such disposition occurs within two (2) years from the
Offering Date or within one (1) year from the Purchase Date on which such shares
were purchased (the "NOTICE PERIOD").  Unless such participant is disposing of
any of such shares during the Notice Period, such participant shall keep the
certificates representing such shares in his or her name (and not in the name of
a nominee) during the Notice Period.  The Company may, at any time during the
Notice Period, place a legend or legends on any certificate representing shares
acquired pursuant to this Plan requesting the Company's transfer agent to notify
the Company of any transfer of the shares.  The obligation of the participant to
provide such notice shall continue notwithstanding the placement of any such
legend on the certificates.

     18.  NO RIGHTS TO CONTINUED EMPLOYMENT.  Neither this Plan nor the grant of
any option hereunder shall confer any right on any employee to remain in the
employ of the Company or any Participating Subsidiary, or restrict the right of
the Company or any Participating Subsidiary to terminate such employee's
employment.

     19.  EQUAL RIGHTS AND PRIVILEGES.  All eligible employees shall have equal
rights and privileges with respect to this Plan so that this Plan qualifies as
an "employee stock purchase plan" within the meaning of Section 423 or any
successor provision of the Code and the related regulations.  Any provision of
this Plan which is inconsistent with Section 423 or any successor provision of
the Code shall, without further act or amendment by the Company, the Committee
or the Board, be reformed to comply with the requirements of Section 423.  This
Section 19 shall take precedence over all other provisions in this Plan.

     20.  NOTICES.  All notices or other communications by a participant to the
Company under or in connection with this 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.

     21.  TERM; STOCKHOLDER APPROVAL.  After this Plan is adopted by the Board,
this Plan will become effective on the date that is the First Offering Date (as
defined above).  This Plan shall be approved by the stockholders of the 

                                       6
<PAGE>
 
Company, in any manner permitted by applicable corporate law, within twelve (12)
months before or after the date this Plan is adopted by the Board. No purchase
of shares pursuant to this Plan shall occur prior to such stockholder approval.
This Plan shall continue until the earlier to occur of (a) termination of this
Plan by the Board (which termination may be effected by the Board at any time),
(b) issuance of all of the shares of Series A Common Stock reserved for issuance
under this Plan, or (c) ten (10) years from the adoption of this Plan by the
Board.

     22.  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
this Plan in the event of such participant's death subsequent to the end of an
Purchase Period but prior to delivery to him of such shares and cash.  In
addition, a participant may file a written designation of a beneficiary who is
to receive any cash from the participant's account under this Plan in the event
of such participant's death prior to a Purchase Date.

         (b)  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 this Plan who is living
at the time of such participant's death, the Company shall deliver such shares
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 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.

     23.  CONDITIONS UPON ISSUANCE OF SHARES; LIMITATION ON SALE 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, the Securities Exchange Act of 1934, the
rules and regulations promulgated thereunder, and the requirements of any stock
exchange or automated quotation system 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.

     24.  APPLICABLE LAW.  The Plan shall be governed by the substantive laws
(excluding the conflict of laws rules) of the State of California.

     25.  AMENDMENT OR TERMINATION OF THIS PLAN.  The Board may at any time
amend, terminate or extend the term of this Plan, except that any such
termination cannot affect options previously granted under this Plan, nor may
any amendment make any change in an option previously granted which would
adversely affect the right of any participant, nor may any amendment be made
without approval of the stockholders of the Company obtained in accordance with
Section 21 hereof within twelve (12) months of the adoption of such amendment
(or earlier if required by Section 21) if such amendment would:

         (a)  increase the number of shares that may be issued under this Plan;
or

         (b)  change the designation of the employees (or class of employees)
eligible for participation in this Plan.
