     4.   Administration of the Plan.
          --------------------------

          (a)  Procedure.
               ---------

               (i)    Multiple Administrative Bodies. The Plan may be
                      ------------------------------
administered by different Committees with respect to different groups of Service
Providers.

               (ii)   Section 162(m). To the extent that the Administrator
                      --------------
determines it to be desirable to qualify Awards granted hereunder as
"performance-based compensation" within the meaning of Section 162(m) of the
Code, the Plan shall be administered by a Committee of two or more "outside
directors" within the meaning of Section 162(m) of the Code.

               (iii)  Rule 16b-3.  To the extent desirable to qualify
                      ----------
transactions hereunder as exempt under Rule 16b-3, the transactions contemplated
hereunder shall be structured to satisfy the requirements for exemption under
Rule 16b-3.

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

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

               (i)    to determine the Fair Market Value;

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

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

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

               (v)    to determine the terms and conditions, not inconsistent
with the terms of the Plan, of any Award granted hereunder. Such terms and
conditions include, but are not limited to, the exercise price, the time or
times when Awards may be exercised (which may be based on performance criteria),
any vesting acceleration or waiver of forfeiture restrictions, and any
restriction or limitation regarding any Award or the shares of Common Stock
relating thereto, based in each case on such factors as the Administrator, in
its sole discretion, shall determine;

               (vi)   to reduce the exercise price of any Award to the then
current Fair Market Value if the Fair Market Value of the Common Stock covered
by such Award shall have declined since the date the Award was granted;

                                      -5-
<PAGE>

               (vii)  to institute an Option Exchange Program;

               (viii) to construe and interpret the terms of the Plan and Awards
granted pursuant to the Plan;

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

               (x)    to modify or amend each Award (subject to Section 17(c) of
the Plan), including the discretionary authority to extend the post-termination
exercisability period of Awards longer than is otherwise provided for in the
Plan;

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

               (xii)  to authorize any person to execute on behalf of the
Company any instrument required to effect the grant of an Award previously
granted by the Administrator;

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

          (c)  Effect of Administrator's Decision. The Administrator's
               ----------------------------------
decisions, determinations and interpretations shall be final and binding on all
Participants.

     5.   Eligibility.  Nonstatutory Stock Options, Stock Purchase Rights  and
          -----------
Stock Appreciation Rights may be granted to Service Providers.  Incentive Stock
Options may be granted only to Employees.

     6.   Limitations.
          -----------

          (a)  Each Option shall be designated in the Option Agreement as either
an Incentive Stock Option or a Nonstatutory Stock Option. However,
notwithstanding such designation, to the extent that the aggregate Fair Market
Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Optionee during any calendar year (under
all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such
Options shall be treated as Nonstatutory Stock Options. For purposes of this
Section 6(a), Incentive Stock Options shall be taken into account in the order
in which they were granted. The Fair Market Value of the Shares shall be
determined as of the time the Option with respect to such Shares is granted.

          (b)  Neither the Plan nor any Award shall confer upon a Participant
any right with respect to continuing the Participant's relationship as a Service
Provider with the Company, nor shall

                                      -6-
<PAGE>

they interfere in any way with the Participant's right or the Company's right to
terminate such relationship at any time, with or without Cause.

          (c)  The following limitations shall apply to grants of Options:

               (i)    No Service Provider shall be granted, in any fiscal year
of the Company, Options to purchase more than 1,000,000 Shares.

               (ii)   In connection with his or her initial service, a Service
Provider may be granted Options to purchase up to an additional 2,000,000
Shares, which shall not count against the limit, set forth in subsection (i)
above.

               (iii)  The foregoing limitations shall be adjusted
proportionately in connection with any change in the Company's capitalization as
described in Section 14.

               (iv)   In applying the limits of subsections (i) and (ii), the
Administrator, to the extent required to qualify Options as "performance-based
compensation" within the meaning of Section 162(m) of the Code, shall apply the
rules of Section 162(m) as necessary or appropriate to reflect an Option that is
cancelled or the exercise price of which is reduced.

     7.   Term of Plan. Subject to Section 21 of the Plan, the Plan shall become
          ------------
effective upon its adoption by the Board. It shall continue in effect for a term
of ten (10) years unless terminated earlier under Section 17 of the Plan.

     8.   Term of Option.  The term of each Option shall be stated in the Award
          --------------
Agreement. In the case of an Incentive Stock Option, the term shall be ten (10)
years from the date of grant or such shorter term as may be provided in the
Award Agreement. Moreover, in the case of an Incentive Stock Option granted to
an Optionee who, at the time the Incentive Stock Option is granted, owns stock
representing more than ten percent (10%) of the total combined voting power of
all classes of stock of the Company or any Parent or Subsidiary, the term of the
Incentive Stock Option shall be five (5) years from the date of grant or such
shorter term as may be provided in the Award Agreement.

     9.   Option Exercise Price and Consideration.
          ---------------------------------------

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

               (i)    In the case of an Incentive Stock Option

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

                                      -7-
<PAGE>

                      (B)  granted to any Employee other than an Employee
described in paragraph (A) immediately above, the per Share exercise price shall
be no less than 100% of the Fair Market Value per Share on the date of grant.

               (ii)   In the case of a Nonstatutory Stock Option, the per Share
exercise price shall be determined by the Administrator.  In the case of a
Nonstatutory Stock Option intended to qualify as "performance-based
compensation" within the meaning of Section 162(m) of the Code, the per Share
exercise price shall be no less than 100% of the Fair Market Value per Share on
the date of grant.

               (iii)  Notwithstanding the preceding, in the event that the
Company or a Subsidiary consummates a transaction described in section 424(a) of
the Code (e.g., the acquisition of property or stock from an unrelated
corporation), persons who become Employees, Directors or Consultants on account
of such transaction may be granted Options in substitution for options granted
by their former employer. If such substitute Options are granted, the
Administrator, in its sole discretion and consistent with section 424(a) of the
Code, shall determine the exercise price of such substitute Options.

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

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

               (i)    cash;

               (ii)   check;

               (iii)  promissory note;

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

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

               (vi)   a reduction in the amount of any Company liability to the
Participant, including any liability attributable to the Participant's
participation in any Company-sponsored deferred compensation program or
arrangement;

               (vii)  any combination of the foregoing methods of payment; or

                                      -8-
<PAGE>

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

     10.  Exercise of Option.
          ------------------

          (a)  Procedure for Exercise; Rights as a Stockholder. Any Option
               -----------------------------------------------
granted hereunder shall be exercisable according to the terms of the Plan and at
such times and under such conditions as determined by the Administrator and set
forth in the Award Agreement. Unless the Administrator provides otherwise,
vesting of Options granted hereunder shall be tolled during any unpaid leave of
absence. An Option may not be exercised for a fraction of a Share.

               An Option shall be deemed exercised when the Company receives:
(i) written or electronic notice of exercise (in accordance with the Option
Agreement) from the person entitled to exercise the Option, and (ii) full
payment for the Shares with respect to which the Option is exercised. Full
payment may consist of any consideration and method of payment authorized by the
Administrator and permitted by the Award Agreement and the Plan. Shares issued
upon exercise of an Option shall be issued in the name of the Participant or, if
requested by the Participant, in the name of the Participant and his or her
spouse. Until the Shares are issued (as evidenced by the appropriate entry on
the books of the Company or of a duly authorized transfer agent of the Company),
no right to vote or receive dividends or any other rights as a Stockholder shall
exist with respect to the Optioned Stock, notwithstanding the exercise of the
Option. The Company shall issue (or cause to be issued) such Shares promptly
after the Option is exercised. No adjustment will be made for a dividend or
other right for which the record date is prior to the date the Shares are
issued, except as provided in Section 14 of the Plan.

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

          (b)  Termination of Relationship as a Service Provider. Subject to
               -------------------------------------------------
Section 14, if a Participant ceases to be a Service Provider (but not in the
event of a Participant's change of status from Employee to Consultant (in which
case an Employee's Incentive Stock Option shall automatically convert to a
Nonstatutory Stock Option on the ninety-first (91/st/) day following such change
of status) or from Consultant to Employee), such Participant may, but only
within such period of time as is specified in the Award Agreement (but in no
event later than the expiration date of the term of such Option as set forth in
the Award Agreement), exercise his or her Option to the extent that the
Participant was entitled to exercise it at the date of such termination. In the
absence of a specified time in the Award Agreement, the Option shall remain
exercisable for three (3) months following the Participant's termination. If, on
the date of termination, the Participant is not vested as to his or her entire
Option, the Shares covered by the unvested portion of the Option shall revert to
the Plan. If, after termination, the Participant does not exercise his or her
Option within the time specified by the Administrator, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.

          (c)  Disability of Optionee.  If a Participant ceases to be a Service
               ----------------------
Provider as a result of the Participant's Disability, the Participant may, but
only within twelve (12) months from

                                      -9-
<PAGE>

the date of such termination (and in no event later than the expiration date of
the term of such Option as set forth in the Award Agreement), exercise his or
her Option to the extent that the Option is vested on the date of termination.
If, on the date of termination, the Participant is not vested as to his or her
entire Option, the Shares covered by the unvested portion of the Option shall
revert to the Plan. If, after termination, the Participant does not exercise his
or her Option within the time specified herein, the Option shall terminate, and
the Shares covered by such Option shall revert to the Plan.

          (d)  Death of Optionee. If a Participant dies while a Service
               -----------------
Provider, the Option may be exercised at any time within twelve (12) months
following the date of death (but in no event later than the expiration of the
term of such Option as set forth in the Award Agreement), by the Participant's
estate or by a person who acquires the right to exercise the Option by bequest
or inheritance, but only to the extent that the Option is vested on the date of
death. If, at the time of death, the Participant is not vested as to his or her
entire Option, the Shares covered by the unvested portion of the Option shall
immediately revert to the Plan. The Option may be exercised by the executor or
administrator of the Participant's estate or, if none, by the person(s) entitled
to exercise the Option under the Participant's will or the laws of descent or
distribution. If the Option is not so exercised within the time specified
herein, the Option shall terminate, and the Shares covered by such Option shall
revert to the Plan.

          (e)  Buyout Provisions. The Administrator may at any time offer to buy
               -----------------
out for a payment in cash or Shares an Option previously granted based on such
terms and conditions as the Administrator shall establish and communicate to the
Participant at the time that such offer is made.

     11.  Stock Purchase Rights.
          ---------------------

          (a)  Rights to Purchase. Stock Purchase Rights may be issued either
               ------------------
alone, in addition to, or in tandem with other Awards granted under the Plan
and/or cash awards made outside of the Plan. After the Administrator determines
that it will offer Stock Purchase Rights under the Plan, it shall advise the
Participant in writing or electronically, of the terms, conditions and
restrictions related to the offer, including the number of Shares that the
offeree shall be entitled to purchase, the price to be paid, and the time within
which the offeree must accept such offer. The offer shall be accepted by
execution of an Award Agreement in the form determined by the Administrator.

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

          (c)  Other Provisions. The Award Agreement shall contain such other
               ----------------
terms, provisions and conditions not inconsistent with the Plan as may be
determined by the Administrator in its sole discretion.

                                      -10-
<PAGE>

          (d)  Rights as a Stockholder. Once the Stock Purchase Right is
               -----------------------
exercised, the purchaser shall have the rights equivalent to those of a
Stockholder, and shall be a Stockholder when his or her purchase is entered upon
the records of the duly authorized transfer agent of the Company. No adjustment
will be made for a dividend or other right for which the record date is prior to
the date the Stock Purchase Right is exercised, except as provided in Section 14
of the Plan.

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

     13.  Formula Option Grants to Outside Directors. Outside Directors shall be
          ------------------------------------------
granted Options in accordance with the following provisions:

          (a)  All Options granted pursuant to this Section shall be

the "First Option").

               (iii) Notwithstanding (i) and (ii) above, an Inside Director who
ceases to be an Inside Director but who remains a Director shall not receive a
First Option.

          (c)  Except as provided in subsection (d) below, each Outside Director

Company occurring after the end of the Company's fiscal year 2001, if
immediately after such meeting, he or she shall continue to serve on the Board
and shall have served on the Board for at least the preceding six (6) months.

          (d)  Notwithstanding the provisions of subsections (b) and (c) hereof,

upon obtaining such stockholder approval of the Plan in accordance with Section
21 hereof.

     14.  Stock Appreciation Rights.
          -------------------------

          (a)  Grant of SARs. Subject to the terms and conditions of the Plan,
               -------------
SARs may be granted to Service Providers at any time and from time to time as
shall be determined by the Administrator, in its sole discretion. The
Administrator shall have complete discretion to determine the number of SARs
granted to any Participant.

          (b)  Exercise Price and Other Terms. The Administrator, subject to the
               ------------------------------
provisions of the Plan, shall have complete discretion to determine the terms
and conditions of SARs granted under the Plan. However, the exercise price of an
SAR shall be not less than one hundred percent (100%) of the Fair Market Value
of a Share on the Grant Date.

          (c)  SAR Agreement. Each SAR grant shall be evidenced by an Award
               -------------
Agreement that shall specify the exercise price, the term of the SAR, the
conditions of exercise, and such other terms and conditions as the
Administrator, in its sole discretion, shall determine.

          (d)  Expiration of SARs. A SAR granted under the Plan shall expire
               ------------------
upon the date determined by the Administrator, in its sole discretion, and set
forth in the Award Agreement. Notwithstanding the foregoing, the rules of
Section 10(b), 10(c) and 10(d) also shall apply to SARs.

          (e)  Payment of SAR Amount. Upon exercise of a SAR, a Participant

                                      -12-
<PAGE>

               (i)   The difference between the Fair Market Value of a Share on
the date of exercise over the exercise price; times

               (ii)  The number of Shares with respect to which the SAR is
exercised.

          (f)  Payment Upon Exercise of SAR. At the discretion of the
               ----------------------------
Administrator, payment for a SAR may be in cash, Shares or a combination
thereof.

     15.  Adjustments Upon Changes in Capitalization, Merger or Asset Sale.
          ----------------------------------------------------------------

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

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

          (c)  Merger or Asset Sale. In the event of a merger of the Company
               --------------------
with or into another corporation, or the sale of all or substantially all of the
assets of the Company (a "Merger"), each outstanding Award shall be assumed or
an equivalent award substituted by the successor corporation or a Parent or
Subsidiary of the successor corporation (the "Successor Corporation"). In the
event that the Successor Corporation refuses to assume or substitute for the
Award, the Optionee shall fully vest in and have the right to exercise the Award
as to all of the Optioned Stock, including Shares as to which it would not
otherwise be vested or exercisable. If an Award becomes fully vested and
exercisable in lieu of assumption or substitution in the event of a Merger, the

                                      -13-
<PAGE>

Administrator shall notify the Optionee in writing or electronically that the
Award shall be fully vested and exercisable for a period of time (determined by
the Administrator in its sole discretion) from the date of such notice, and the
Award shall terminate upon the expiration of such period. For the purposes of
this Section 14(c), the Award shall be considered assumed if, following the
Merger, the award confers the right to purchase or receive, for each Share of
Optioned Stock subject to the Award immediately prior to the Merger, the
consideration (whether stock, cash, or other securities or property) received in
the Merger by holders of Common Stock for each Share held on the effective date
of the transaction (and if holders were offered a choice of consideration, the
type of consideration chosen by the holders of a majority of the outstanding
Shares); provided, however, that if such consideration received in the Merger is
not solely common stock of the Successor Corporation or its Parent, the
Administrator may, with the consent of the Successor Corporation, provide for
the consideration to be received upon the exercise of the Award, for each Share
of Optioned Stock subject to the Award, to be solely common stock of the
Successor Corporation or its Parent equal in fair market value to the per share
consideration received by holders of Common Stock in the Merger.

     16.  Change of Control. In the event of a Change of Control, each
          -----------------
outstanding Option held by an Outside Director shall vest and become exercisable
in full as to all of the Optioned Stock, including Shares as to which the
Outside Director would not otherwise be vested or exercisable. If an Option
becomes fully vested and exercisable as provided in this paragraph, the
Administrator shall notify the Optionee in writing or electronically that the
Option shall be fully vested and exercisable for a period of time (determined by
the Administrator in its sole discretion) from the date of such notice, and the
Option shall terminate upon the expiration of such period.

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

     18.  Amendment and Termination of the Plan.
          -------------------------------------

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

          (b)  Stockholder Approval. The Company shall obtain Stockholder
               --------------------
approval of any Plan amendment to the extent necessary and desirable to comply
with Applicable Laws .

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

                                      -14-
<PAGE>

     19.  Conditions Upon Issuance of Shares.
          ----------------------------------

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

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

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

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

     22.  Stockholder Approval.  The Plan shall be subject to approval by the
          --------------------
Stockholders of the Company within twelve (12) months after the date the Plan is
adopted.  Such Stockholder approval shall be obtained in the manner and to the
degree required under Applicable Laws.

                                      -15-
