                               MICRUS CORPORATION

                                 1998 STOCK PLAN

     1.   Purposes of the Plan. The purposes of this Stock Plan are to attract
and retain the best available personnel for positions of substantial
responsibility, to provide additional incentive to Employees, Directors and
Consultants and to promote the success of the Company's business. Options
granted under the Plan may be Incentive Stock Options or Nonstatutory Stock
Options, as determined by the Administrator at the time of grant. Stock Purchase
Rights may also be granted under the Plan.

THE WALL STREET JOURNAL or such other source as the Administrator deems
reliable;

               (ii) If the Common Stock is regularly quoted by a recognized

without having been exercised in full, or is surrendered pursuant to an Option
Exchange Program, the unpurchased Shares which were subject thereto shall become
available for future grant or sale under the Plan (unless the Plan has
terminated). However, Shares that have actually been issued under the Plan, upon
exercise of either an Option or Stock Purchase Right, shall not be returned to
the Plan and shall not become available for future distribution under the Plan,
except that if Shares of Restricted Stock are repurchased by the Company at
their original purchase price, such Shares shall become available for future
grant under the Plan.

     4.   Administration of the Plan.

          (a)  Administrator. The Plan shall be administered by the Board or a
Committee appointed by the Board, which Committee shall be constituted to comply
with Applicable Laws.

          (b)  Powers of the Administrator. Subject to the provisions of the
Plan and, in the case of a Committee, the specific duties delegated by the Board
to such Committee, and subject to the approval of any relevant authorities, 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 from time to time be granted hereunder;

              (iii) to determine the number of Shares to be covered by each
such award granted hereunder;

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

               (v)  to determine the terms and conditions, 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
Common Stock relating thereto, based in each case on such factors as the
Administrator, in its sole discretion, shall determine;

               (vi) to determine whether and under what circumstances an Option
may be settled in cash under subsection 9(e) instead of Common Stock;

              (vii) to reduce the exercise price of any Option to the then
current Fair Market Value if the Fair Market Value of the Common Stock covered
by such Option has declined since the date the Option was granted;

             (viii) to initiate an Option Exchange Program;

               (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 allow Optionees to satisfy withholding tax obligations by
electing to have the Company withhold from the Shares to be issued upon exercise
of an Option or Stock Purchase Right that number of Shares having a Fair Market
Value equal to the amount required to be withheld. The Fair Market Value of the
Shares to be withheld shall be determined on the date that the amount of tax to
be withheld is to be determined. All elections by Optionees to have Shares

                                      -4-
<PAGE>

withheld for this purpose shall be made in such form and under such conditions
as the Administrator may deem necessary or advisable; and

               (xi) to construe and interpret the terms of the Plan and awards
granted pursuant to the Plan.

          (c)  Effect of Administrator's Decision. All decisions, determinations
and interpretations of the Administrator shall be final and binding on all
Optionees.

     5.   Eligibility.

          (a)  Nonstatutory Stock Options and Stock Purchase Rights may be
granted to Service Providers. Incentive Stock Options may be granted only to
Employees.

          (b)  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 5(b), 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.

          (c)  Neither the Plan nor any Option or Stock Purchase Right shall
confer upon any Optionee any right with respect to continuing the Optionee's
relationship as a Service Provider with the Company, nor shall it interfere in
any way with his or her right or the Company's right to terminate such
relationship at any time, with or without cause.

     6.   Term of 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 sooner
terminated under Section 14 of the Plan.

     7.   Term of Option. The term of each Option shall be stated in the Option
Agreement; provided, however, that the term shall be no more than ten (10) years
from the date of grant thereof. In the case of an Incentive Stock Option granted
to an Optionee who, at the time the Option is granted, owns stock representing
more than ten percent (10%) of the voting power of all classes of stock of the
Company or any Parent or Subsidiary, the term of the Option shall be five (5)
years from the date of grant or such shorter term as may be provided in the
Option Agreement.

     8.   Option Exercise Price and Consideration.

          (a)  The per share exercise price for the Shares to be issued upon
exercise of an Option shall be such price as is determined by the Administrator,
but shall be subject to the following:

                                      -5-
<PAGE>
               (i)  In the case of an Incentive Stock Option

                    (A)  granted to an Employee who, at the time of grant of
such Option, 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
exercise price shall be no less than 110% of the Fair Market Value per Share on
the date of grant.

                    (B)  granted to any other Employee, 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

                    (A)  granted to a Service Provider who, at the time of grant
of such Option, 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 exercise price shall be no less than 110% of the Fair Market Value per Share
on the date of grant.

                    (B)  granted to any other Service Provider, the per Share
exercise price shall be no less than 85% 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 other than as required above pursuant to a merger or
other corporate transaction.

          (b)  The consideration to be paid for the Shares to be issued upon
exercise of an Option, including the method of payment, shall be determined by
the Administrator (and, in the case of an Incentive Stock Option, shall be
determined at the time of grant). Such consideration may consist of (1) cash,
(2) check, (3) promissory note, (4) other Shares which (x) in the case of Shares
acquired upon exercise of an Option, have been owned by the Optionee for more
than six months on the date of surrender, and (y) have a Fair Market Value on
the date of surrender equal to the aggregate exercise price of the Shares as to
which such Option shall be exercised, (5) consideration received by the Company
under a cashless exercise program implemented by the Company in connection with
the Plan, or (6) any combination of the foregoing methods of payment. In making
its determination as to the type of consideration to accept, the Administrator
shall consider if acceptance of such consideration may be reasonably expected to
benefit the Company.

     9.   Exercise of Option.

          (a)  Procedure for Exercise; Rights as a Shareholder. Any Option
granted hereunder shall be exercisable according to the terms hereof at such
times and under such conditions as determined by the Administrator and set forth
in the Option Agreement. Except in the case of Options granted to Officers,
Directors and Consultants, Options shall become exercisable at a rate of no less
than 20% per year over five (5) years from the date the Options are granted.
Unless the

                                      -6-
<PAGE>

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 Option Agreement and the Plan. Shares issued
upon exercise of an Option shall be issued in the name of the Optionee or, if
requested by the Optionee, in the name of the Optionee and his or her spouse.
Until the Shares are issued (as evidenced by the appropriate entry on the books
of the Company or of a duly authorized transfer agent of the Company), no right
to vote or receive dividends or any other rights as a shareholder shall exist
with respect to the Shares, notwithstanding the exercise of the Option. The
Company shall issue (or cause to be issued) such Shares promptly after the
Option is exercised. No adjustment will be made for a dividend or other right
for which the record date is prior to the date the Shares are issued, except as
provided in Section 12 of the Plan.

               Exercise of an Option in any manner shall result in a decrease in
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, such Optionee may exercise his or her Option
within such period of time as is specified in the Option Agreement (of at least
thirty (30) days) 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 the 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
(of at least six (6) months) 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.

                                      -7-
<PAGE>

          (d)  Death of Optionee. If an Optionee dies while a Service Provider,
the Option may be exercised within such period of time as is specified in the
Option Agreement (of at least six (6) months) to the extent that the Option is
vested on the date of death (but in no event later than the expiration of the
term of such Option as set forth in the Option Agreement) by the Optionee's
estate or by a person who acquires the right to exercise the Option by bequest
or inheritance. In the absence of a specified time in the Option Agreement, the
Option shall remain exercisable for twelve (12) months following the Optionee's
termination. If, at the time of death, the Optionee is not vested as to the
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.

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

     10.  Non-Transferability of Options and Stock Purchase Rights. The Options
and Stock Purchase Rights 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.

     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 of the terms, conditions and restrictions
related to the offer, including the number of Shares that such person shall be
entitled to purchase, the price to be paid, and the time within which such
person must accept such offer. The terms of the offer shall comply in all
respects with Section 260.140.42 of Title 10 of the California Code of
Regulations. 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 such rate as the
Administrator may determine. Except with respect to Shares purchased by
Officers, Directors and Consultants, the repurchase option shall in no case
lapse at a rate of less than 20% per year over five (5) years from the date of
purchase.

                                      -8-
<PAGE>

          (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 Shareholder. Once the Stock Purchase Right is
exercised, the purchaser shall have rights equivalent to those of a shareholder
and shall be a shareholder when his or her purchase is entered upon the records
of the duly authorized transfer agent of the Company. No adjustment shall 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 12 of
the Plan.

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

          (a)  Changes in Capitalization. Subject to any required action by the
shareholders of the Company, the number of shares of Common Stock covered by
each outstanding Option or Stock Purchase Right, and the number of shares of
Common Stock which have been authorized for issuance under the Plan but as to
which no Options or Stock Purchase Rights have yet been granted or which have
been returned to the Plan upon cancellation or expiration of an Option or Stock
Purchase Right, as well as the price per share of Common Stock covered by each
such outstanding Option or Stock Purchase Right, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of issued shares of Common Stock effected without receipt
of consideration by the Company. 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 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 or Stock Purchase Right until
fifteen (15) days prior to such transaction as to all of the Optioned Stock
covered thereby, including Shares as to which the Option or Stock Purchase Right
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.

                                      -9-
<PAGE>

          (c)  Merger or Asset Sale. In the event of a merger of the Company
with or into another corporation, or the sale of substantially all of the assets
of the Company, each outstanding Option and Stock Purchase Right 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 sale of assets, the
Administrator shall notify the Optionee in writing or electronically that the
Option or Stock Purchase Right shall be fully 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 paragraph, the Option or Stock Purchase Right shall be considered assumed
if, following the merger or sale of assets, the option or right confers the
right to purchase or receive, for each Share of Optioned Stock subject to the
Option or Stock Purchase Right immediately prior to the merger or sale of
assets, the consideration (whether stock, cash, or other securities or property)
received in the merger or sale of assets by holders of Common Stock for each
Share held on the effective date of the transaction (and if holders were offered
a choice of consideration, the type of consideration chosen by the holders of a
majority of the outstanding Shares); provided, however, that if such
consideration received in the merger or sale of assets 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 sale of assets.

     13.  Time of Granting Options and Stock Purchase Rights. The date of grant
of an Option or Stock Purchase Right shall, for all purposes, be the date on
which the Administrator makes the determination granting such Option or Stock
Purchase Right, or such other date as is determined by the Administrator. Notice
of the determination shall be given to each Service Provider to whom an Option
or Stock Purchase Right is so granted within a reasonable time after the date of
such grant.

     14.  Amendment and Termination of the Plan.

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

          (b)  Shareholder Approval. The Board shall obtain shareholder 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

                                      -10-
<PAGE>

exercise the powers granted to it hereunder with respect to Options granted
under the Plan prior to the date of such termination.

     15.  Conditions Upon Issuance of Shares.

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

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

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

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

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

     19.  Information to Optionees and Purchasers. The Company shall provide to
each Optionee and to each individual who acquires Shares pursuant to the Plan,
not less frequently than annually during the period such Optionee or purchaser
has one or more Options or Stock Purchase Rights outstanding, and, in the case
of an individual who acquires Shares pursuant to the Plan, during the period
such individual owns such Shares, copies of annual financial statements. The
Company shall not be required to provide such statements to key employees whose
duties in connection with the Company assure their access to equivalent
information.

behalf of an Optionee (a "CASHLESS EXERCISE PROCEDURE"), provided that if the
Company extends or arranges for the extension of credit to an Optionee under any
Cashless Exercise Procedure, no Officer or Director may participate in that
Cashless Exercise Procedure;

                  (iii) cancellation of any debt owed by the Company or any
Affiliate to the Optionee by the Company including without limitation waiver of
compensation due or accrued for services previously rendered to the Company; and

                  (iv) any combination of the methods of payment permitted by
any paragraph of this Section 6.4.

            (d) The Administrator may also permit any other form or method of
payment for Option Shares permitted by Applicable Law.

      6.5 NONASSIGNABILITY OF OPTIONS.

      Except as determined by the Administrator, no Option shall be assignable
or otherwise transferable by the Optionee except by will or by the laws of
descent and distribution. However, Options may be transferred and exercised in
accordance with a Domestic Relations Order and may be exercised by a guardian or
conservator appointed to act for the Optionee. Incentive Stock Options may only
be assigned in compliance with Section 7(h).

      6.6 SUBSTITUTE OPTIONS.

      The Board may cause the Company to grant Substitute Options in connection
with the acquisition by the Company or an Affiliate of equity securities of any
entity (including by

                                       10
<PAGE>
merger, tender offer, or other similar transaction) or of all or a portion of
the assets of any entity. Any such substitution shall be effective on the
effective date of the acquisition. Substitute Options may be Nonstatutory
Options or Incentive Stock Options. Unless and to the extent specified otherwise
by the Board, Substitute Options shall have the same terms and conditions as the
options they replace, except that (subject to the provisions of Section 10)
Substitute Options shall be Options to purchase Shares rather than equity
securities of the granting entity and shall have an Option Price determined by
the Board.

      6.7 REPRICINGS.

      In furtherance of, and not in limitation of the provisions of Section 10,
Options may be repriced, replaced or regranted through cancellation or
modification without stockholder approval.

7.    INCENTIVE STOCK OPTIONS.

      The following rules apply only to Incentive Stock Options and only to the
extent these rules are more restrictive than the rules that would otherwise
apply under this Plan. With the consent of the Optionee, or where this Plan
provides that an action may be taken notwithstanding any other provision of this
Plan, the Administrator may deviate from the requirements of this Section,
notwithstanding that any Incentive Stock Option modified by the Administrator
will thereafter be treated as a Nonstatutory Option.

            (a) The Expiration Date of an Incentive Stock Option shall not be
later than ten years from its Grant Date, with the result that no Incentive
Stock Option may be exercised after the expiration of ten years from its Grant
Date.

            (b) Any Incentive Stock Option granted to a Ten Percent Stockholder,
must have an Expiration Date that is not later than five years from its Grant
Date, with the result that no such Option may be exercised after the expiration
of five years from the Grant Date. A "TEN PERCENT STOCKHOLDER" is any person
who, directly or by attribution under Section 424(d) of the Code, owns stock
possessing more than ten percent of the total combined voting power of all
classes of stock of the Company or of any Affiliate on the Grant Date.

            (c) No Incentive Stock Option may be granted more than ten years
from the date this Plan was approved by the Board.

            (d) Options intended to be incentive stock options under Section 422
of the Code that are granted to any single Optionee under all incentive stock
option plans of the Company and its Affiliates, including incentive stock
options granted under this Plan, may not vest at a rate of more than $100,000 in
Fair Market Value of stock (measured on the grant dates of the options) during
any calendar year. For this purpose, an option vests with respect to a given
share of stock the first time its holder may purchase that share,
notwithstanding any right of the Company to repurchase that share. Unless the
administrator of that option plan specifies otherwise in the related agreement
governing the option, this vesting limitation shall be applied by, to the extent
necessary to satisfy this $ 100,000 rule, treating certain stock options that
were intended to be incentive stock options under Section 422 of the Code as
Nonstatutory Options.

                                       11
<PAGE>
The stock options or portions of stock options to be reclassified as
Nonstatutory Options are those with the highest option prices, whether granted
under this Plan or any other equity compensation plan of the Company or any
Affiliate that permits that treatment. This Section 7(c) shall not cause an
Incentive Stock Option to vest before its original vesting date or cause an
Incentive Stock Option that has already vested to cease to be vested.

            (e) In order for an Incentive Stock Option to be exercised for any
form of payment other than those described in Section 6.4(b), that right must be
stated at the time of grant in the Option Agreement relating to that Incentive
Stock Option.

            (f) The Option Price of an Incentive Stock Option shall never be
less than the Fair Market Value of the Shares at the Grant Date. The Option
Price for the Shares covered by an Incentive Stock Option granted to a Ten
Percent Stockholder shall never be less than 110% of the Fair Market Value of
the Shares at the Grant Date.

            (g) Incentive Stock Options may be granted only to Employees. If an
Optionee changes status from an Employee to a Consultant, that Optionee's
Incentive Stock Options become Nonstatutory Options if not exercised within the
time period described in Section 7(i) (determined by treating that change in
status as a Termination solely for purposes of this Section 7(g)).

            (h) No rights under an Incentive Stock Option may be transferred by
the Optionee, other than by will or the laws of descent and distribution. During
the life of the Optionee, an Incentive Stock Option may be exercised only by the
Optionee. The Company's compliance with a Domestic Relations Order, or the
exercise of an Incentive Stock Option by a guardian or conservator appointed to
act for the Optionee, shall not violate this Section 7(h).

            (i) An Incentive Stock Option shall be treated as a Nonstatutory
Option if it remains exercisable after, and is not exercised within, the
three-month period beginning with the Optionee's Termination for any reason
other than the Optionee's death or disability (as defined in Section 22(e) of
the Code). In the case of Termination due to death, an Incentive Stock Option
shall continue to be treated as an Incentive Stock Option if it remains
exercisable after, and is not exercised within, the three month period after the
Optionee's Termination provided it is exercised before the Expiration Date. In
the case of Termination due to disability, an Incentive Stock Option shall be
treated as a Nonstatutory Option if it remains exercisable after, and is not
exercised within, one year after the Optionee's Termination.

            (j) An Incentive Stock Option may only be modified by the Board.

8.    STOCK APPRECIATION RIGHTS, STOCK AWARDS AND CASH AWARDS

      8.1   STOCK APPRECIATION RIGHTS.

      The following rules apply to SARs:

            (a) GENERAL. SARs may be granted either alone, in addition to, or in
tandem with other Awards granted under this Plan. The Administrator may grant
SARs to eligible

                                       12
<PAGE>
participants subject to terms and conditions not inconsistent with this Plan and
determined by the Administrator. The specific terms and conditions applicable to
the Awardee shall be provided for in the Award Agreement. SARs shall be
exercisable, in whole or in part, at such times as the Administrator shall
specify in the Award Agreement. The grant or vesting of a SAR may be made
contingent on the achievement of Objectively Determinable Performance
Conditions.

            (b) EXERCISE OF SARS. Upon the exercise of an SAR, in whole or in
part, an Awardee shall be entitled to a payment in an amount equal to the excess
of the Fair Market Value of a fixed number of Shares covered by the exercised
portion of the SAR on the date of exercise, over the Fair Market Value of the
Shares covered by the exercised portion of the SAR on the Grant Date. The amount
due to the Awardee upon the exercise of a SAR shall be paid in cash, Shares or a
combination thereof, over the period or periods specified in the Award
Agreement. An Award Agreement may place limits on the amount that may be paid
over any specified period or periods upon the exercise of a SAR, on an aggregate
basis or as to any Awardee. A SAR shall be considered exercised when the Company
receives written notice of exercise in accordance with the terms of the Award
Agreement from the person entitled to exercise the SAR. If a SAR has been
granted in tandem with an Option, upon the exercise of the SAR, the number of
shares that may be purchased pursuant to the Option shall be reduced by the
number of shares with respect to which the SAR is exercised.

            (c) NONASSIGNABILITY OF SARS. Except as determined by the
Administrator, no SAR shall be assignable or otherwise transferable by the
Awardee except by will or by the laws of descent and distribution.
Notwithstanding anything herein to the contrary, SARs may be transferred and
exercised in accordance with a Domestic Relations Order.

            (d) SUBSTITUTE SARS. The Board may cause the Company to grant
Substitute SARs in connection with the acquisition by the Company or an
Affiliate of equity securities of any entity (including by merger) or all or a
portion of the assets of any entity. Any such substitution shall be effective on
the effective date of the acquisition. Unless and to the extent specified
otherwise by the Board, Substitute SARs shall have the same terms and conditions
as the options they replace, except that (subject to the provisions of Section
9) Substitute SARs shall be exercisable with respect to the Fair Market Value of
Shares rather than equity securities of the granting entity and shall be on
terms that, as determined by the Board in its sole and absolute discretion,
properly reflects the substitution.

            (e) REPRICINGS. A SAR may not be repriced, replaced or regranted,
through cancellation or modification without stockholder approval.

      8.2   STOCK AWARDS.

      The following rules apply to all Stock Awards:

            (a) GENERAL. The specific terms and conditions of a Stock Award
applicable to the Awardee shall be provided for in the Award Agreement. The
Award Agreement shall state the number of Shares that the Awardee shall be
entitled to receive or purchase, the terms and conditions on which the Shares
shall vest, the price to be paid, whether Shares are to be delivered at the time
of grant or at some deferred date specified in the Award Agreement (e.g. a
restricted

                                       13
<PAGE>
stock unit award agreement), whether the Award is payable solely in Shares, cash
or either and, if applicable, the time within which the Awardee must accept such
offer. The offer shall be accepted by execution of the Award Agreement. The
Administrator may require that all Shares subject to a right of repurchase or
risk of forfeiture be held in escrow until such repurchase right or risk of
forfeiture lapses. The grant or vesting of a Stock Award may be made contingent
on the achievement of Objectively Determinable Performance Conditions.

            (b) RIGHT OF REPURCHASE. If so provided in the Award Agreement,
Award Shares acquired pursuant to a Stock Award may be subject to repurchase by
the Company or an Affiliate if not vested in accordance with the Award
Agreement.

            (c) FORM OF PAYMENT. The Administrator shall determine the
acceptable form and method of payment for exercising a Stock Award. Acceptable
forms of payment for all Award Shares are cash, check or wire transfer,
denominated in U.S. dollars except as specified by the Administrator for
non-U.S. sub-plans. In addition, the Administrator may permit payment to be made
by any of the methods permitted with respect to the exercise of Options pursuant
to Section 6.4.

            (d) NONASSIGNABILITY OF STOCK AWARDS. Except as determined by the
Administrator, no Stock Award shall be assignable or otherwise transferable by
the Awardee except by will or by the laws of descent and distribution.
Notwithstanding anything to the contrary herein, Stock Awards may be transferred
and exercised in accordance with a Domestic Relations Order.

            (e) SUBSTITUTE STOCK AWARD. The Board may cause the Company to grant
Substitute Stock Awards in connection with the acquisition by the Company or an
Affiliate of equity securities of any entity (including by merger) or all or a
portion of the assets of any entity. Unless and to the extent specified
otherwise by the Board, Substitute Stock Awards shall have the same terms and
conditions as the stock awards they replace, except that (subject to the
provisions of Section 10) Substitute Stock Awards shall be Stock Awards to
purchase Shares rather than equity securities of the granting entity and shall
have a Purchase Price that, as determined by the Board in its sole and absolute
discretion, properly reflects the substitution. Any such Substituted Stock Award
shall be effective on the effective date of the acquisition.

      8.3   CASH AWARDS.

      The following rules apply to all Cash Awards:

      Cash Awards may be granted either alone, in addition to, or in tandem with
other Awards granted under this Plan. After the Administrator determines that it
will offer a Cash Award, it shall advise the Awardee, by means of an Award
Agreement, of the terms, conditions and restrictions related to the Cash Award.

9.    EXERCISE OF AWARDS

      9.1   IN GENERAL.

                                       14
<PAGE>
      An Award shall be exercisable in accordance with this Plan and the Award
Agreement under which it is granted.

      9.2   TIME OF EXERCISE.

      Options and Stock Awards shall be considered exercised when the Company
receives: (a) written notice of exercise from the person entitled to exercise
the Option or Stock Award, (b) full payment, or provision for payment, in a form
and method approved by the Administrator, for the Shares for which the Option or
Stock Award is being exercised, and (c) with respect to Nonstatutory Options,
payment, or provision for payment, in a form approved by the Administrator, of
all applicable withholding taxes due upon exercise. An Award may not be
exercised for a fraction of a Share. SARs shall be considered exercised when the
Company receives written notice of the exercise from the person entitled to
exercise the SAR.

      9.3   ISSUANCE OF AWARD SHARES.

      The Company shall issue Award Shares in the name of the person properly
exercising the Award. If the Awardee is that person and so requests, the Award
Shares shall be issued in the name of the Awardee and the Awardee's spouse. The
Company shall endeavor to issue Award Shares promptly after an Award is
exercised or after the Grant Date of a Stock Award, as applicable. Until Award
Shares are actually issued, as evidenced by the appropriate entry on the stock
register of the Company or its transfer agent, the Awardee will not have the
rights of a stockholder with respect to those Award Shares, even though the
Awardee has completed all the steps necessary to exercise the Award. No
adjustment shall be made for any dividend, distribution, or other right for
which the record date precedes the date the Award Shares are issued, except as
provided in Section 10.

      9.4   TERMINATION

            (a) IN GENERAL. Except as provided in an Award Agreement or in
writing by the Administrator, including in an Award Agreement, and as otherwise
provided in Sections 9.4(b), (c), (d) and (e) after an Awardee's Termination,
the Awardee's Awards shall be exercisable to the extent (but only to the extent)
they are vested on the date of that Termination and only during the ninety (90)
days after the Termination, but in no event after the Expiration Date. To the
extent the Awardee does not exercise an Award within the time specified for
exercise, the Award shall automatically terminate.

            (b) LEAVES OF ABSENCE. Unless otherwise provided in the Award
Agreement, no Award may be exercised more than three months after the beginning
of a leave of absence, other than a personal or medical leave approved by an
authorized representative of the Company with employment guaranteed upon return.
Awards shall not continue to vest during a leave of absence, unless otherwise
determined by the Administrator with respect to an approved personal or medical
leave with employment guaranteed upon return.

            (c) DEATH OR DISABILITY. Unless otherwise provided by the
Administrator, if an Awardee's Termination is due to death or disability (as
determined by the Administrator with respect to all Awards other than Incentive
Stock Options and as defined by Section 22(e) of the

                                       15
<PAGE>
Code with respect to Incentive Stock Options), all Awards of that Awardee to the
extent exercisable at the date of that Termination may be exercised for one year
after that Termination, but in no event after the Expiration Date. In the case
of Termination due to death, an Award may be exercised as provided in Section
17. In the case of Termination due to disability, if a guardian or conservator
has been appointed to act for the Awardee and been granted this authority as
part of that appointment, that guardian or conservator may exercise the Award on
behalf of the Awardee. Death or disability occurring after an Awardee's
Termination shall not cause the Termination to be treated as having occurred due
to death or disability. To the extent an Award is not so exercised within the
time specified for its exercise, the Award shall automatically terminate.

            (d) DIVESTITURE. If an Awardee's Termination is due to a
Divestiture, the Board may take any one or more of the actions described in
Section 10.3 or 10.4 with respect to the Awardee's Awards.

            (e) ADMINISTRATOR DISCRETION. Notwithstanding the provisions of
Section 9.4 (a)-(e), the Plan Administrator shall have complete discretion,
exercisable either at the time an Award is granted or at any time while the
Award remains outstanding, to:

                  (i) Extend the period of time for which the Award is to remain
exercisable, following the Awardee's Termination, from the limited exercise
period otherwise in effect for that Award to such greater period of time as the
Administrator shall deem appropriate, but in no event beyond the Expiration
Date; and/or

                  (ii) Permit the Award to be exercised, during the applicable
post-Termination exercise period, not only with respect to the number of vested
Shares for which such Award may be exercisable at the time of the Awardee's
Termination but also with respect to one or more additional installments in
which the Awardee would have vested had the Awardee not been subject to
Termination.

            (f) CONSULTING OR EMPLOYMENT RELATIONSHIP. Nothing in this Plan or
in any Award Agreement, and no Award or the fact that Award Shares remain
subject to repurchase rights, shall: (A) interfere with or limit the right of
the Company or any Affiliate to terminate the employment or consultancy of any
Awardee at any time, whether with or without cause or reason, and with or
without the payment of severance or any other compensation or payment, or (B)
interfere with the application of any provision in any of the Company's or any
Affiliate's charter documents or Applicable Law relating to the election,
appointment, term of office, or removal of a Director.

10.   CERTAIN TRANSACTIONS AND EVENTS

      10.1  IN GENERAL.

      Except as provided in this Section 10, no change in the capital structure
of the Company, merger, sale or other disposition of assets or a subsidiary,
change in control, issuance by the Company of shares of any class of securities
or securities convertible into shares of any class of securities, exchange or
conversion of securities, or other transaction or event shall require or be

                                       16
<PAGE>
the occasion for any adjustments of the type described in this Section 10.
Additional provisions with respect to the foregoing transactions are set forth
in Section 14.3.

      10.2  CHANGES IN CAPITAL STRUCTURE.

      In the event of any stock split, reverse stock split, recapitalization,
combination or reclassification of stock, stock dividend, spin-off, or similar
change to the capital structure of the Company (not including a Corporate
Transaction or Change in Control), the Board shall make whatever adjustments it
concludes are appropriate to: (a) the number and type of Awards that may be
granted under this Plan, (b) the number and type of Options that may be granted
to any individual under this Plan, (c) the terms of any SAR, (d) the Purchase
Price of any Stock Award, (e) the Option Price and number and class of
securities issuable under each outstanding Option, and (f) the repurchase price
of any securities substituted for Award Shares that are subject to repurchase
rights. The specific adjustments shall be determined by the Board. Unless the
Board specifies otherwise, any securities issuable as a result of any such
adjustment shall be rounded down to the next lower whole security. The Board
need not adopt the same rules for each Award or each Awardee.

      10.3  CORPORATE TRANSACTIONS.

      Except for grants to Non-Employee Directors pursuant to Section 11 herein,
in the event of (a) 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 shall be binding on all Participants), (b) 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, (c) the sale of all or substantially all of the assets of the
Company, or (d) the acquisition, sale, or transfer of more than 50% of the
outstanding shares of the Company by tender offer or similar transaction (each,
a "CORPORATE TRANSACTION"), any or all outstanding Awards may be assumed,
converted or replaced by the successor corporation (if any), which assumption,
conversion or replacement shall be binding on all participants under this Plan.
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 held by the participants, substantially similar shares or other property
subject to repurchase restrictions no less favorable to the participant. In the
event such successor corporation (if any) does not assume or substitute Awards,
as provided above, pursuant to a transaction described in this Subsection 10.3,
the vesting with respect to such Awards shall fully and immediately accelerate
or the repurchase rights of the Company shall fully and immediately terminate,
as the case may be, so that the Awards may be exercised or the repurchase rights
shall terminate before, or otherwise in connection with the closing or
completion of the Corporate Transaction or event, but then terminate.
Notwithstanding anything in this Plan to the contrary, the Committee may, in its
sole discretion, provide that the vesting of

                                       17
<PAGE>
any or all Award Shares subject to vesting or right of repurchase shall
accelerate or lapse, as the case may be, upon a transaction described in this
Section 10.3. If the Committee exercises such discretion with respect to
Options, such Options shall 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.
Subject to any greater rights granted to participants under the foregoing
provisions of this Section 10.3, in the event of the occurrence of any Corporate
Transaction, any outstanding Awards shall be treated as provided in the
applicable agreement or plan of merger, consolidation, dissolution, liquidation,
or sale of assets.

      10.4  CHANGES IN CONTROL.

      The Board may also, but need not, specify that other transactions or
events constitute a "CHANGE IN CONTROL". The Board may do that either before or
after the transaction or event occurs. Examples of transactions or events that
the Board may treat as Changes in Control are: (a) any person or entity,
including a "group" as contemplated by Section 13(d)(3) of the Exchange Act,
acquires securities holding 30% or more of the total combined voting power or
value of the Company, or (b) as a result of or in connection with a contested
election of Company Directors, the persons who were Company Directors
immediately before the election cease to constitute a majority of the Board. In
connection with a Change in Control, notwithstanding any other provision of this
Plan, the Board may, but need not, take any one or more of the actions described
in Section 10.3. In addition, the Board may extend the date for the exercise of
Awards (but not beyond their original Expiration Date). The Board need not adopt
the same rules for each Award or each Awardee.

      10.5  DIVESTITURE.

      If the Company or an Affiliate sells or otherwise transfers equity
securities of an Affiliate to a person or entity other than the Company or an
Affiliate, or leases, exchanges or transfers all or any portion of its assets to
such a person or entity, then the Board may specify that such transaction or
event constitutes a "DIVESTITURE". In connection with a Divestiture,
notwithstanding any other provision of this Plan, the Board may, but need not,
take one or more of the actions described in Section 10.3 or 10.4 with respect
to Awards of Award Shares held by, for example, Employees, Directors or
Consultants for whom that transaction or event results in a Termination. The
Board need not adopt the same rules for each Award or Awardee.

      10.6  DISSOLUTION.

      If the Company adopts a plan of dissolution, the Board may cause Awards to
be fully vested and exercisable (but not after their Expiration Date) before the
dissolution is completed but contingent on its completion and may cause the
Company's repurchase rights on Award Shares to lapse upon completion of the
dissolution. The Board need not adopt the same rules for each Award or each
Awardee. Notwithstanding anything herein to the contrary, in the event of a
dissolution of the Company, to the extent not exercised before the earlier of
the completion of the dissolution or their Expiration Date, Awards shall
terminate immediately prior to the dissolution.

                                       18
<PAGE>
      10.7  CUT-BACK TO PRESERVE BENEFITS.

      If the Administrator determines that the net after-tax amount to be
realized by any Awardee, taking into account any accelerated vesting,
termination of repurchase rights, or cash payments to that Awardee in connection
with any transaction or event set forth in this Section 10 would be greater if
one or more of those steps were not taken or payments were not made with respect
to that Awardee's Awards or Award Shares, then, at the election of the Awardee,
to such extent, one or more of those steps shall not be taken and payments shall
not be made.

11.   AUTOMATIC OPTION GRANTS TO NON-EMPLOYEE DIRECTORS

      11.1  AUTOMATIC OPTION GRANTS TO NON-EMPLOYEE DIRECTORS

            (a) GRANT DATES. Option grants to Non-Employee Directors shall be
made on the dates specified below:

                  (i) Each Non-Employee Director who is first elected or
appointed to the Board at any time after the Effective Date of this Plan shall
automatically be granted, on the date of such initial election or appointment,
an Option to purchase 40,000 Shares (the "INITIAL GRANT").

                  (ii) Commencing in 2005, on the date of each annual
stockholders meeting, each individual who is to continue to serve as a
Non-Employee Director shall automatically be granted an Option to purchase
20,000 Shares (the "ANNUAL GRANT"), provided, however, that such individual has
served as a Non-Employee Director for at least six (6) months.

            (b) EXERCISE PRICE.

                  (i) The Option Price shall be equal to one hundred percent
(100%) of the Fair Market Value of the Shares on the Option grant date.

                  (ii) The Option Price shall be payable in one or more of the
alternative forms authorized pursuant to Section 6.4. Except to the extent the
sale and remittance procedure specified thereunder is utilized, payment of the
Option Price must be made on the date of exercise.

            (c) OPTION TERM. Each Option shall have a term of ten (10) years
measured from the Option grant date.

            (d) EXERCISE AND VESTING OF OPTIONS. Except as otherwise determined
by the whole Board, the Shares underlying each Option granted pursuant to
Section 11.1 shall vest and be exercisable as set forth below.

                  (i) INITIAL GRANT. The Shares underlying each Option issued
pursuant to the Initial Grant shall vest and be exercisable as to 2.0833% of the
Shares at the end of each full succeeding month from the date of grant, rounded
down to the nearest whole Share, for so

                                       19
<PAGE>
long as the Non-Employee Director continuously remains a Director of, or a
Consultant to, the Company.

                  (ii) ANNUAL GRANT. The Shares underlying each Option issued
pursuant to the Annual Grant shall vest and be exercisable as to 8.3333% of the
Shares at the end of each full succeeding month from the date of grant, rounded
down to the nearest whole Share, for so long as the Non-Employee Director
continuously remains a Director of, or a Consultant to, the Company.

            (e) TERMINATION OF SERVICE. The following provisions shall govern
the exercise of any Options held by the Awardee at the time the Awardee ceases
to serve as a Non-Employee Director, Employee or Consultant:

                  (i) IN GENERAL. Except as otherwise provided in Section 10.3,
after cessation of service (the "CESSATION DATE"), the Awardee's Options shall
be exercisable to the extent (but only to the extent) they are vested on the
Cessation Date and only during the three months after such Cessation Date, but
in no event after the Expiration Date. To the extent the Awardee does not
exercise an Option within the time specified for exercise, the Option shall
automatically terminate.

                  (ii) DEATH OR DISABILITY. If an Awardee's cessation of service
is due to death or disability (as determined by the Board), all Options of that
Awardee, to the extent exercisable upon such Cessation Date, may be exercised
for one year after the Cessation Date, but in no event after the Expiration
Date. In the case of a cessation of service due to death, an Option may be
exercised as provided in Section 16. In the case of a cessation of service due
to disability, if a guardian or conservator has been appointed to act for the
Awardee and been granted this authority as part of that appointment, that
guardian or conservator may exercise the Option on behalf of the Awardee. Death
or disability occurring after an Awardee's cessation of service shall not cause
the cessation of service to be treated as having occurred due to death or
disability. To the extent an Option is not so exercised within the time
specified for its exercise, the Option shall automatically terminate.

            (f) BOARD DISCRETION. The Awards under this Section 11.1 are not
intended as the exclusive Awards that may be made to Non-Employee Directors
under this Plan. The Board may, in its discretion, amend the Plan with respect
to the terms of the Awards herein, may add or substitute other types of Awards
or may temporarily or permanently suspend Awards hereunder, all without approval
of the Company's stockholders.

      11.2  CERTAIN TRANSACTIONS AND EVENTS

            (a) In the event of a Corporate Transaction while the Awardee
remains a Non-Employee Director, the Shares at the time subject to each
outstanding Option held by such Awardee pursuant to Section 11, but not
otherwise vested, shall automatically vest in full so that each such Option
shall, immediately prior to the effective date of the Corporate Transaction,
become exercisable for all the Shares as fully vested Shares and may be
exercised for any or all of those vested Shares. Immediately following the
consummation of the Corporate Transaction, each Option shall terminate and cease
to be outstanding, except to the extent assumed by the successor corporation (or
Affiliate thereof).

            (b) In the event of a Change in Control while the Awardee remains a
Non-Employee Director, the Shares at the time subject to each outstanding Option
held by such Awardee pursuant to Section 11, but not otherwise vested, shall
automatically vest in full so that each such Option shall, immediately prior to
the effective date of the Change in Control, become exercisable for all the
Shares as fully vested Shares and may be exercised for any or all of those
vested Shares. Each such Option shall remain exercisable for such fully vested
Shares until the expiration or sooner termination of the Option term in
connection with a Change in Control.

            (c) Each Option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Awardee in consummation of such Corporate Transaction had
the Option been exercised immediately prior to such Corporate Transaction.
Appropriate adjustments shall also be made to the Option Price payable per share
under each outstanding Option, provided the aggregate Option Price payable for
such securities shall remain the same. To the extent the actual holders of the
Company's outstanding Common Stock receive cash consideration for their Common
Stock in consummation of the Corporate Transaction, the successor corporation
may, in connection with the assumption of the outstanding Options granted
pursuant to Section 11, substitute one or more shares of its own common stock
with a fair market value equivalent to the cash consideration paid per share of
Common Stock in such Corporate Transaction.

            (d) The grant of Options pursuant to Section 11 shall in no way
affect the right of the Company to adjust, reclassify, reorganize or otherwise
change its capital or business structure or to merge, consolidate, dissolve,
liquidate or sell or transfer all or any part of its business or assets.

            (e) The remaining terms of each Option granted pursuant to Section
11 shall, as applicable, be the same as terms in effect for Awards granted under
this Plan. Notwithstanding the foregoing, the provisions of Section 9.4 and
Section 10 shall not apply to Options granted pursuant to Section 11.

      11.3  LIMITED TRANSFERABILITY OF OPTIONS.

      Each Option granted pursuant to Section 11 may be assigned in whole or in
part during the Awardee's lifetime to one or more members of the Awardee's
family or to a trust established exclusively for one or more such family members
or to an entity in which the Awardee is

                                       21
<PAGE>
majority owner or to the Awardee's former spouse, to the extent such assignment
is in connection with the Awardee 's estate or financial plan or pursuant to a
Domestic Relations Order. The assigned portion may only be exercised by the
person or persons who acquire a proprietary interest in the Option pursuant to
the assignment. The terms applicable to the assigned portion shall be the same
as those in effect for the Option immediately prior to such assignment and shall
be set forth in such documents issued to the assignee as the Administrator may
deem appropriate. The Awardee may also designate one or more persons as the
beneficiary or beneficiaries of his or her outstanding Options under Section 11,
and those Options shall, in accordance with such designation, automatically be
transferred to such beneficiary or beneficiaries upon the Awardee's death while
holding those Options. Such beneficiary or beneficiaries shall take the
transferred Options subject to all the terms and conditions of the applicable
Award Agreement evidencing each such transferred Option, including (without
limitation) the limited time period during which the Option may be exercised
following the Awardee's death.

12.   WITHHOLDING AND TAX REPORTING

      12.1  TAX WITHHOLDING ALTERNATIVES.

            (a) GENERAL. Whenever Award Shares are issued or become free of
restrictions, the Company may require the Awardee to remit to the Company an
amount sufficient to satisfy any applicable tax withholding requirement, whether
the related tax is imposed on the Awardee or the Company. The Company shall have
no obligation to deliver Award Shares or release Award Shares from an escrow or
permit a transfer of Award Shares until the Awardee has satisfied those tax
withholding obligations. Whenever payment in satisfaction of Awards is made in
cash, the payment will be reduced by an amount sufficient to satisfy all tax
withholding requirements.

            (b) METHOD OF PAYMENT. The Awardee shall pay any required
withholding using the forms of consideration described in Section 6.4(b), except
that, in the discretion of the Administrator, the Company may also permit the
Awardee to use any of the forms of payment described in Section 6.4(c). The
Administrator, in its sole discretion, may also permit Award Shares to be
withheld to pay required withholding. If the Administrator permits Award Shares
to be withheld, the Fair Market Value of the Award Shares withheld, as
determined as of the date of withholding, shall not exceed the amount determined
by the applicable minimum statutory withholding rates.

      12.2  REPORTING OF DISPOSITIONS.

      Any holder of Option Shares acquired under an Incentive Stock Option shall
promptly notify the Administrator, following such procedures as the
Administrator may require, of the sale or other disposition of any of those
Option Shares if the disposition occurs during: (a) the longer of two years
after the Grant Date of the Incentive Stock Option and one year after the date
the Incentive Stock Option was exercised, or (b) such other period as the
Administrator has established.

                                       22
<PAGE>
13.   COMPLIANCE WITH LAW

      The grant of Awards and the issuance and subsequent transfer of Award
Shares shall be subject to compliance with all Applicable Law, including all
applicable securities laws. Awards may not be exercised, and Award Shares may
not be transferred, in violation of Applicable Law. Thus, for example, Awards
may not be exercised unless: (a) a registration statement under the Securities
Act is then in effect with respect to the related Award Shares, or (b) in the
opinion of legal counsel to the Company, those Award Shares may be issued in
accordance with an applicable exemption from the registration requirements of
the Securities Act and any other applicable securities laws. The failure or
inability of the Company to obtain from any regulatory body the authority
considered by the Company's legal counsel to be necessary or useful for the
lawful issuance of any Award Shares or their subsequent transfer shall relieve
the Company of any liability for failing to issue those Award Shares or
permitting their transfer. As a condition to the exercise of any Award or the
transfer of any Award Shares, the Company may require the Awardee to satisfy any
requirements or qualifications that may be necessary or appropriate to comply
with or evidence compliance with any Applicable Law.

14.   AMENDMENT OR TERMINATION OF THIS PLAN OR OUTSTANDING AWARDS

      14.1  AMENDMENT AND TERMINATION.

      The Board may at any time amend, suspend, or terminate this Plan.

      14.2  STOCKHOLDER APPROVAL.

      The Company shall obtain the approval of the Company's stockholders for
any amendment to this Plan if stockholder approval is necessary or desirable to
comply with any Applicable Law or with the requirements applicable to the grant
of Awards intended to be Incentive Stock Options. The Board may also, but need
not, require that the Company's stockholders approve any other amendments to
this Plan.

      14.3  EFFECT.

      No amendment, suspension, or termination of this Plan, and no modification
of any Award even in the absence of an amendment, suspension, or termination of
this Plan, shall impair any existing contractual rights of any Awardee unless
the affected Awardee consents to the amendment, suspension, termination, or
modification. Notwithstanding anything herein to the contrary, no such consent
shall be required if the Board determines, in its sole and absolute discretion,
that the amendment, suspension, termination, or modification: (a) is required or
advisable in order for the Company, this Plan or the Award to satisfy Applicable
Law, to meet the requirements of any accounting standard or to avoid any adverse
accounting treatment, or (b) in connection with any transaction or event
described in Section 10, is in the best interests of the Company or its
stockholders. The Board may, but need not, take the tax or accounting
consequences to affected Awardees into consideration in acting under the
preceding sentence. Those decisions shall be final, binding and conclusive.
Termination of this Plan shall not affect the Administrator's ability to
exercise the powers granted to it under this Plan with respect to

                                       23
<PAGE>
Awards granted before the termination of Award Shares issued under such Awards
even if those Award Shares are issued after the termination.

15.   RESERVED RIGHTS

      15.1  NONEXCLUSIVITY OF THIS PLAN.

      This Plan shall not limit the power of the Company or any Affiliate to
adopt other incentive arrangements including, for example, the grant or issuance
of stock options, stock, or other equity-based rights under other plans.

      15.2  UNFUNDED PLAN.

      This Plan shall be unfunded. Although bookkeeping accounts may be
established with respect to Awardees, any such accounts will be used merely as a
convenience. The Company shall not be required to segregate any assets on
account of this Plan, the grant of Awards, or the issuance of Award Shares. The
Company and the Administrator shall not be deemed to be a trustee of stock or
cash to be awarded under this Plan. Any obligations of the Company to any
Awardee shall be based solely upon contracts entered into under this Plan, such
as Award Agreements. No such obligations shall be deemed to be secured by any
pledge or other encumbrance on any assets of the Company. Neither the Company
nor the Administrator shall be required to give any security or bond for the
performance of any such obligations.

16.   SPECIAL ARRANGEMENTS REGARDING AWARD SHARES

      16.1  ESCROW OF STOCK CERTIFICATES.

      To enforce any restrictions on Award Shares, the Administrator may require
their holder to deposit the certificates representing Award Shares, with stock
powers or other transfer instruments approved by the Administrator endorsed in
blank, with the Company or an agent of the Company to hold in escrow until the
restrictions have lapsed or terminated. The Administrator may also cause a
legend or legends referencing the restrictions to be placed on the certificates.

      16.2  REPURCHASE RIGHTS.

            (a) GENERAL. If a Stock Award is subject to vesting conditions, the
Company shall have the right, during the seven months after the Awardee's
Termination, to repurchase any or all of the Award Shares that were unvested as
of the date of that Termination. The repurchase price shall be determined by the
Administrator in accordance with this Section 16.2 which shall be either (i) the
Purchase Price for the Award Shares (minus the amount of any cash dividends paid
or payable with respect to the Award Shares for which the record date precedes
the repurchase) or (ii) the lower of (A) the Purchase Price for the Shares or
(B) the Fair Market Value of those Award Shares as of the date of the
Termination. The repurchase price shall be paid in cash. The Company may assign
this right of repurchase.

                                       24
<PAGE>
            (b) PROCEDURE. The Company or its assignee may choose to give the
Awardee a written notice of exercise of its repurchase rights under this Section
16.2. However, the Company's failure to give such a notice shall not affect its
rights to repurchase Award Shares. The Company must, however, tender the
repurchase price during the period specified in this Section 16.2 for exercising
its repurchase rights in order to exercise such rights.

17.   BENEFICIARIES

      An Awardee may file a written designation of one or more beneficiaries who
are to receive the Awardee's rights under the Awardee's Awards after the
Awardee's death. An Awardee may change such a designation at any time by written
notice. If an Awardee designates a beneficiary, the beneficiary may exercise the
Awardee's Awards after the Awardee's death. If an Awardee dies when the Awardee
has no living beneficiary designated under this Plan, the Company shall allow
the executor or administrator of the Awardee's estate to exercise the Award or,
if there is none, the person entitled to exercise the Option under the Awardee's
will or the laws of descent and distribution. In any case, no Award may be
exercised after its Expiration Date.

18.   MISCELLANEOUS

      18.1  GOVERNING LAW.

      This Plan, the Award Agreements and all other agreements entered into
under this Plan, and all actions taken under this Plan or in connection with
Awards or Award Shares, shall be governed by the laws of the State of Delaware.

      18.2  DETERMINATION OF VALUE.

      Fair Market Value shall be determined as follows:

            (a) LISTED STOCK. If the Shares are traded on any established stock
exchange or quoted on a national market system, Fair Market Value shall be the
closing sales price for the Shares as quoted on that stock exchange or system
for the date the value is to be determined (the "VALUE DATE") as reported in The
Wall Street Journal or a similar publication. If no sales are reported as having
occurred on the Value Date, Fair Market Value shall be that closing sales price
for the last preceding trading day on which sales of Shares are reported as
having occurred. If no sales are reported as having occurred during the five
trading days before the Value Date, Fair Market Value shall be the closing bid
for Shares on the Value Date. If Shares are listed on multiple exchanges or
systems, Fair Market Value shall be based on sales or bid prices on the primary
exchange or system on which Shares are traded or quoted.

            (b) STOCK QUOTED BY SECURITIES DEALER. If Shares are regularly
quoted by a recognized securities dealer but selling prices are not reported on
any established stock exchange or quoted on a national market system, Fair
Market Value shall be the mean between the high bid and low asked prices on the
Value Date. If no prices are quoted for the Value Date, Fair Market Value shall
be the mean between the high bid and low asked prices on the last preceding
trading day on which any bid and asked prices were quoted.

                                       25
<PAGE>
            (c) NO ESTABLISHED MARKET. If Shares are not traded on any
established stock exchange or quoted on a national market system and are not
quoted by a recognized securities dealer, the Administrator (following
guidelines established by the Board or Committee) will determine Fair Market
Value in good faith. The Administrator will consider the following factors, and
any others it considers significant, in determining Fair Market Value: (i) the
price at which other securities of the Company have been issued to purchasers
other than Employees, Directors, or Consultants, (ii) the Company's
stockholder's equity, prospective earning power, dividend-paying capacity, and
non-operating assets, if any, and (iii) any other relevant factors, including
the economic outlook for the Company and the Company's industry, the Company's
position in that industry, the Company's goodwill and other intellectual
property, and the values of securities of other businesses in the same industry.

      18.3  RESERVATION OF SHARES.

      During the term of this Plan, the Company shall at all times reserve and
keep available such number of Shares as are still issuable under this Plan.

      18.4  ELECTRONIC COMMUNICATIONS.

      Any Award Agreement, notice of exercise of an Award, or other document
required or permitted by this Plan may be delivered in writing or, to the extent
determined by the Administrator, electronically. Signatures may also be
electronic if permitted by the Administrator.

      18.5  NOTICES.

      Unless the Administrator specifies otherwise, any notice to the Company
under any Option Agreement or with respect to any Awards or Award Shares shall
be in writing (or, if so authorized by Section 18.4, communicated
electronically), shall be addressed to the Secretary of the Company, and shall
only be effective when received by the Secretary of the Company.
