     4. ADMINISTRATION OF THE PLAN.

          (a) PROCEDURE.

               (i) MULTIPLE ADMINISTRATIVE BODIES. Different Committees with
respect to different groups of Service Providers may administer the Plan.

               (ii) SECTION 162(m). To the extent that the Administrator
determines it to be desirable to qualify Options granted hereunder as
"performance-based compensation" within the meaning of


                                      -4-
<Page>

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 Options and Stock
Purchase Rights may be granted hereunder;

               (iii) to determine the number of shares of Common Stock to be
covered by each Option and Stock Purchase Right 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 Option or Stock Purchase Right granted hereunder.
Such terms and conditions include, but are not limited to, the exercise price,
the time or times when Options or Stock Purchase Rights may be exercised (which
may be based on performance criteria), any vesting acceleration or waiver of
forfeiture restrictions, and any restriction or limitation regarding any Option
or Stock Purchase Right or the shares of Common Stock relating thereto, based in
each case on such factors as the Administrator, in its sole discretion, shall
determine;

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

               (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 establish, amend and rescind rules and regulations
relating to the Plan, including rules and regulations relating to sub-plans
established for the purpose of satisfying applicable foreign laws;

               (x) to modify or amend each Option or Stock Purchase Right
(subject to Section 16(c) of the Plan), including the discretionary authority to
extend the post-termination exercisability period of Options longer than is
otherwise provided for in the Plan;


                                      -5-
<Page>

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

               (xii) to authorize any person to execute on behalf of the Company
any instrument required to effect the grant of an Option or Stock Purchase Right
previously granted by the Administrator;

               (xiii) to correct any defect, supply any omission, or reconcile
any inconsistency in the Plan, or in any Option Agreement, in a manner and to
the extent it shall deem necessary, all of which determinations and
interpretations made by the Administrator shall be conclusive and binding on all
Optionees, any other holders of Options and on their legal representatives and
beneficiaries; and

               (xiv) except to the extent prohibited by, or impermissible in
order to obtain treatment desired by the Administrator under, applicable law or
rule, to allocate or delegate all or any portion of its powers and
responsibilities to any one or more of its members or to any person(s) selected
by it, subject to revocation or modification by the Administrator of such
allocation or delegation.

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

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

     5. ELIGIBILITY. Nonstatutory Stock Options and Stock Purchase 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 Option or Stock Purchase Right shall
confer upon an Optionee any right with respect to continuing the Optionee's
relationship as a Service Provider with the Company, nor shall they interfere in
any way with the Optionee's right or the Company's right to terminate such
relationship at any time, with or without cause.

          (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 200,000 Shares.


                                      -6-

<Page>

               (ii) In connection with his or her initial service, a Service
Provider may be granted Options to purchase up to an additional [400,000]
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 13.

               (iv) If an Option is cancelled in the same fiscal year of the
Company in which it was granted (other than in connection with a transaction
described in Section 13), the cancelled Option will be counted against the
limits set forth in subsections (i) and (ii) above. For this purpose, if the
exercise price of an Option is reduced, the transaction will be treated as a
cancellation of the Option and the grant of a new Option.

     7. TERM OF PLAN. Subject to Section 20 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 16 of the Plan.

     8. TERM OF OPTION. The term of each Option shall be stated in the Option
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
Option 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 Option Agreement.

     9. OPTION EXERCISE PRICE AND CONSIDERATION.

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

               (i) In the case of an Incentive Stock Option

                    (1) 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.

                    (2) 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 foregoing, Options may be granted with
a per Share exercise price of less than 100% of the Fair Market Value per Share
on the date of grant pursuant to a merger or other corporate transaction.


                                      -7-
<Page>

          (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, provided Shares acquired directly or
indirectly from the Company, (A) have been owned by the Optionee for more than
six (6) months on the date of surrender, and (B) have a Fair Market Value on the
date of surrender equal to the aggregate exercise price of the Shares as to
which said Option shall be exercised;

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

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

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

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

     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 Option Agreement. Unless the Administrator provides otherwise,
vesting of Options granted hereunder shall be suspended 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 Option Agreement and the Plan. Shares issued
upon exercise of an Option shall be issued in the name of the Optionee or, if
requested by the Optionee, in the name of the Optionee and his or her spouse or
in the name of a family trust of which the Optionee is a trustee. 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


                                      -8-
<Page>

Shares promptly after the Option is exercised; provided that if the Company
shall be advised by counsel that certain requirements under the Federal, state
or foreign securities laws must be met before Shares may be issued under this
Plan, the Company shall notify all persons who have been issued Options, and the
Company shall have no liability for failure to issue Shares under any exercise
of Options because of delay while such requirements are being met or the
inability of the Company to comply with such requirements. 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 13 of the Plan.

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

          (b) TERMINATION OF RELATIONSHIP AS A SERVICE PROVIDER. If an Optionee
ceases to be a Service Provider, other than upon the Optionee's death or
Disability, the Optionee may exercise his or her Option within such period of
time as is specified in the Option Agreement to the extent that the Option is
vested on the date of termination (but in no event later than the expiration of
the term of such Option as set forth in the Option Agreement). In the absence of
a specified time in the Option Agreement, the Option shall remain exercisable
for three (3) months following the Optionee's termination. If, on the date of
termination, the Optionee is not vested as to his or her entire Option, the
Shares covered by the unvested portion of the Option shall revert to the Plan.
If, after termination, the Optionee does not exercise his or her Option within
the time specified by the Administrator, the Option shall terminate, and the
Shares covered by such Option shall revert to the Plan.

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

          (d) DEATH OF OPTIONEE. If an Optionee dies while a Service Provider,
the Option may be exercised following the Optionee's death within such period of
time as is specified in the Option Agreement to the extent that the Option is
vested on the date of death (but in no event may the Option be exercised later
than the expiration of the term of such Option as set forth in the Option
Agreement), by the Optionee's designated beneficiary, provided such beneficiary
has been designated prior to the Optionee's death in a form acceptable to the
Administrator. If no such beneficiary has been designated by the Optionee, then
such Option may be exercised by the personal representative of the Optionee's
estate or by the person(s) to whom the Option is transferred pursuant to the
Optionee's will or in accordance with the laws of descent and distribution. In
the absence of a specified time in the Option Agreement, the Option shall remain
exercisable for twelve (12) months following the Optionee's death. If, at the
time of death, the Optionee is not vested as to his or her entire Option, the
Shares covered by the unvested portion of the Option shall immediately revert to
the Plan. 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.

     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
offeree in writing or electronically, by means of a Notice of Grant, of the
terms, conditions and restrictions related to the offer, including the number of
Shares that the offeree shall be entitled to purchase, the price to be paid, and
the time within which the offeree must accept such offer. The offer shall be
accepted by execution of a Restricted Stock Purchase Agreement in the form
determined by the Administrator.

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

          (c) OTHER PROVISIONS. The Restricted Stock Purchase 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.

          (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 13
of the Plan.

     12. TRANSFERABILITY OF OPTIONS AND STOCK PURCHASE RIGHTS. Unless determined
otherwise by the Administrator, an Option or Stock Purchase Right may not be
sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner
other than by will or by the laws of descent or distribution and may be
exercised, during the lifetime of the Optionee, only by the Optionee. If the
Administrator makes an Option or Stock Purchase Right transferable, such Option
or Stock Purchase Right shall contain such additional terms and conditions as
the Administrator deems appropriate.

     13. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, DISSOLUTION, MERGER OR
CHANGE IN CONTROL.

          (a) CHANGES IN CAPITALIZATION. Subject to any required action by the
stockholders of the Company, the number of shares of Common Stock that have been
authorized for issuance under the Plan but as to which no Options or Stock
Purchase Rights have yet been granted or which have been returned to the Plan
upon cancellation or expiration of an Option or Stock Purchase Right, the number
of shares that may be added annually to the shares reserved under the Plan
(pursuant to Section 3(a)(i)), the number of Shares as well as the price per
share of Common Stock covered by each such outstanding Option or Stock Purchase
Right, shall be proportionately adjusted for any increase or decrease in the
number of issued shares of Common Stock resulting from a stock split, reverse
stock split, stock dividend, combination or reclassification of the Common
Stock, or any other increase or decrease in the number of issued shares of
Common Stock effected without receipt of consideration by the Company; provided,
however, that conversion of any convertible securities of the Company shall not
be deemed to have been "effected without receipt of consideration." Such
adjustment shall be made by the Board, whose determination in that respect shall
be final, binding and conclusive. Except as expressly provided herein, no
issuance by the Company of shares of stock of any class, or securities
convertible into shares of stock of any class, shall affect, and no


                                      -10-
<Page>

adjustment by reason thereof shall be made with respect to, the number or price
of shares of Common Stock subject to an Option or Stock Purchase Right.

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

          (c) MERGER OR CHANGE IN CONTROL. In the event of a merger of the
Company with or into another corporation, or a Change in Control, each
outstanding Option and Stock Purchase Right shall be assumed or an equivalent
option or right substituted by the successor corporation or a Parent or
Subsidiary of the successor corporation.

               In the event that the successor corporation refuses to assume or
substitute for the Option or Stock Purchase Right, the Optionee shall fully vest
in and have the right to exercise the Option or Stock Purchase Right as to all
of the Optioned Stock, including Shares as to which it would not otherwise be
vested or exercisable. If an Option or Stock Purchase Right becomes fully vested
and exercisable in lieu of assumption or substitution in the event of a merger
or Change in Control, the Administrator shall notify the Optionee in writing or
electronically that the Option or Stock Purchase Right shall be fully vested and
exercisable for a period of fifteen (15) days from the date of such notice, and
the Option or Stock Purchase Right shall terminate upon the expiration of such
period.

               For the purposes of this subsection (c), the Option or Stock
Purchase Right shall be considered assumed if, following the merger or Change in
Control, the option or right confers the right to purchase or receive, for each
Share of Optioned Stock subject to the Option or Stock Purchase Right
immediately prior to the merger or Change in Control, the consideration (whether
stock, cash, or other securities or property) received in the merger or Change
in Control by holders of Common Stock for each Share held on the effective date
of the transaction (and if holders were offered a choice of consideration, the
type of consideration chosen by the holders of a majority of the outstanding
Shares); provided, however, that if such consideration received in the merger or
Change in Control 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 Option or
Stock Purchase Right, for each Share of Optioned Stock subject to the Option or
Stock Purchase Right, to be solely common stock of the successor corporation or
its Parent equal in fair market value to the per share consideration received by
holders of Common Stock in the merger or Change in Control.

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

     15. 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 Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.
Termination of the Plan shall not affect the Administrator's ability to exercise
the powers granted to it hereunder with respect to Options granted under the
Plan prior to the date of such termination.

     16. CONDITIONS UPON ISSUANCE OF SHARES.

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

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

     17. 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.

     18. 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.

     19. 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.
