                          EXODUS COMMUNICATIONS, INC.

                          1998 EQUITY INCENTIVE PLAN

                        As Adopted January 15, 1998 and
                  Amended June 2, 1999 and February 29, 2000

          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 29,000,000 Shares plus (a) any authorized shares
not issued or subject to outstanding grants under the Company's 1997 Equity
Incentive Plan the ("Prior Plan") on the Effective Date (as defined in Section
19 below); (b) shares that are subject to issuance upon exercise of an option
granted under the Prior Plan but cease to be subject to such option for any
reason other than exercise of such option; and (c) shares that were issued under
the Prior Plan which are repurchased by the Company at the original issue price
or forfeited. Subject to Sections 2.2 and 18, Shares that are subject to: (x)
issuance upon exercise of an Option but cease to be subject to such Option for
any reason other than exercise of such Option; (y) an Award granted hereunder
but are forfeited or are repurchased by the Company at the original issue price;
and (z) an Award 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.

                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.

          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 750,000
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 1,250,000 Shares in the calendar year in which they
commence their employment.  A person may be granted more than one Award under
this Plan.

          4.   ADMINISTRATION.

               4.1    Committee Authority. This Plan will be administered by the
Committee or by the Board acting as the Committee. Subject to the general
purposes, terms and conditions of this Plan, and to the direction of the Board,
the Committee will have full power to implement and carry out this Plan. Without
limitation, the Committee will have the authority to:

          (a)  construe and interpret this Plan, any Award Agreement and any
               other agreement or document executed pursuant to this Plan;

          (b)  prescribe, amend and rescind rules and regulations relating to
               this Plan or any Award;

          (c)  select persons to receive Awards;

          (d)  determine the form and terms of Awards;

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

          (f)  determine whether Awards will be granted singly, in combination
               with, in tandem with, in replacement of, or as alternatives to,
               other Awards under this Plan or any other incentive or
               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
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
<PAGE>

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 for Cause or because of
               Participant's 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 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)  Notwithstanding the provisions in paragraph 5.6(a) above, if a
               Participant is terminated for Cause, neither the Participant, the
               Participant's estate nor such other person who may then hold the
               Option shall be entitled to exercise any Option with respect to
               any Shares whatso-
<PAGE>

               ever, after termination of service, whether or not after
               termination of service the Participant may receive payment from
               the Company or Subsidiary for vacation pay, for services rendered
               prior to termination, for services rendered for the day on which
               termination occurs, for salary in lieu of notice, or for any
               other benefits. 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 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.
<PAGE>

               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 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
<PAGE>

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 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 Partici-
<PAGE>

pant 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 corporate or
capital structure of the Company will be subject to the same restrictions as the
Restricted Stock; provided, further, that the Participant will have no right to
retain such stock dividends or stock distributions with respect to Shares that
are repurchased at the Participant's Purchase Price or Exercise Price pursuant
to Section 12.

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

          11.  TRANSFERABILITY.  Awards granted under this Plan, and any
interest therein, will not be transferable or assignable by Participant, and may
not be made subject to execution, attachment or similar process, otherwise than
by will or by the laws of descent and distribution or as determined by the
Committee and set forth in the Award Agreement with respect to Awards that are
not ISOs. During the lifetime of the Participant an Award will be exercisable
only by the Participant, and any elections with respect to an Award may be made
only by the Participant unless otherwise determined by the Committee and set
forth in the Award Agreement with respect to Awards that are not ISOs.

          12.  RESTRICTIONS ON SHARES.  At the discretion of the Committee, the
Company may reserve to itself and/or its assignee(s) in the Award Agreement a
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
delivered under this Plan will be subject to such stock transfer orders, legends
and other restrictions as the Committee may deem necessary or advisable,
including restrictions under any applicable federal, state or foreign securities
law, or any rules, regulations and other requirements of the SEC or any stock
exchange or automated quotation system upon which the Shares may be listed 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 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
<PAGE>

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 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,
such Awards will expire on such transaction at such time and on such conditions
as the Committee will determine; provided, however, that the
<PAGE>

Committee may, in its sole discretion, provide that the vesting of any or all
Awards granted pursuant to this Plan will accelerate. If the Committee exercises
such discretion with respect to Options, such Options will become exercisable in
full prior to the consummation of such event at such time 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 at such time as
determined by the Committee.

               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 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 pursuant to such increase will be canceled, any Shares issued pursuant
to any Award granted pursuant to such increase will be canceled, and any
purchase of Shares pursuant to such increase 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.

                          EXODUS COMMUNICATIONS, INC.

                       1998 EMPLOYEE STOCK PURCHASE PLAN

                        As Adopted January 15, 1998 and
                Amended January 27, 1998 and February 29, 2000

     1.   Establishment of Plan.  Exodus Communications, Inc. (the "Company")
proposes to grant options for purchase of the Company's  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 6,600,000 shares of the Company's Common Stock is reserved for
issuance under this Plan.  In addition, on each January 1, the aggregate number
of shares of the Company's Common Stock reserved for issuance under this Plan
shall be increased automatically by a number of shares equal to one percent (1%)
of the total outstanding shares of the Company as of the immediately preceding
December 31; provided, however, that such annual evergreen increases shall in no
event cause the number of shares issuable under this Plan to exceed 20,000,000
shares. 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 customarily employed for twenty (20) hours or
less per week;

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

          (c)  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 its Participating Subsidiaries or who, as a result of being granted an
option under this Plan with respect to such Offering Period, would 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
<PAGE>

          (d)  individuals who provide services to the Company or any of its
Participating Subsidiaries as independent contractors who are reclassified as
common law employees for any reason except for federal income and employment tax
purposes.

     5.   Offering Dates.  The offering periods of this Plan (each, an "Offering
Period") shall be of twenty-four (24) months duration commencing on May 1 and
November 1 of each year and ending on April 30 and October 31 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 Common Stock are available on the Nasdaq National Market (the
"First Offering Date") and shall end on April 30, 2000.  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 more than five
and 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 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
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 five (5) days before such Offering Date. Notwithstanding the
foregoing, the Committee may set a later time for filing the subscription
agreement authorizing payroll deductions 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 five (5) 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  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  Common
Stock on the Offering Date (but in no event less than the par value of a share
of the Company's  Common Stock), or (ii) eighty-five percent (85%) of the fair
market value of a share of the Company's  Common Stock on the Purchase Date (but
in no event less than the par value of a share of the Company's  Common Stock),
provided, however, that the number of shares of the Company's  Common Stock
subject to any option granted pursuant to this Plan shall not exceed the lesser
of (x) the maximum number of shares set by the Committee pursuant to Section
10(c) below with respect to the applicable Purchase Date, or (y) 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  Common Stock shall be determined as provided in Section 8 below.

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

          (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
<PAGE>

the Company's Common Stock determined as follows:

          (a)  if such 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 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 Common Stock is listed or admitted to trading as
               reported in The Wall Street Journal;

          (c)  if such 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 Common Stock are
               initially offered for sale to the public by the Company's
               underwriters in the initial public offering of the Company's
               Common Stock pursuant to a registration statement filed with the
               Securities and Exchange Commission (the "SEC") under the
               Securities Act of 1933, as amended (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 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. 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.

          (b)  A participant may decrease or 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 Purchase 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)  A participant may reduce his or her payroll deduction percentage
to zero during an Offering Period by filing with the Treasury Department a
request for cessation of payroll deductions. Such reduction shall be effective
beginning with the next payroll period commencing more than fifteen (15) days
after the Treasury Department's receipt of the request and no further payroll
deductions will be made for the duration of the Offering Period. Payroll
deductions credited to the participant's account prior to the effective date of
the request shall be used to purchase shares of Common Stock of the Company in
accordance with Section (e) below. A participant may not resume making payroll
deductions during the Offering Period in which he or she reduced his or her
payroll deductions to zero.

          (d)  All payroll deductions made for a participant are credited to his
or her account under this Plan and
<PAGE>

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.

          (e)  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
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
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 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
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.

          (f)  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.

          (g)  During a participant's lifetime, his or her 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. The Company shall automatically suspend
the payroll deductions of any participant as necessary to enforce such limit
provided that when the Company automatically resumes such payroll deductions,
the Company must apply the rate in effect immediately prior to such suspension.

          (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  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. The maximum
number of shares which may be purchased by any employee at any single Purchase
Date (hereinafter the "Maximum Share Amount") shall be 8,000, until otherwise
determined by the Committee not less than thirty (30) days prior to the
commencement of any Offering Period. 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. The Maximum Share
Amount 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.
<PAGE>

          (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.

          (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 in Section 6 above for initial
participation in this Plan.

          (c)  If the Fair Market Value on the first day of the current Offering
Period in which a participant is enrolled is higher than the Fair Market Value
on the first day of any subsequent Offering Period, the Company will
automatically enroll such participant in the subsequent Offering Period.  Except
with respect to the first 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.  In the event that the Fair
Market Value on the First Offering Date is higher than the Fair Market Value on
the first day of the second Offering Period, any funds accumulated in a
participant's account prior to the first day of the second Offering Period will
be applied to the purchase of shares on the Purchase Date next following the
first day of such second 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 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  Common Stock covered by each option
under this Plan which has not yet been exercised and the number of shares of
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 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 Common Stock of the
Company resulting from a stock split or the payment of a stock dividend (but
only on the 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
<PAGE>

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.

     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 this Plan
shall terminate as of a date fixed by the Committee and give each participant
the right to purchase shares under this Plan prior to such termination.  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 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 all or 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, the Plan will terminate
immediately prior to the consummation of such transaction, unless otherwise
provided by the Committee.

     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 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 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 below) 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 in
writing 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").  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
<PAGE>

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 First Offering Date (as defined above).
This Plan shall be approved by the stockholders of the 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  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, as
amended, 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 above 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.
