reacquired Common Stock. If an Option expires or becomes unexercisable for any
reason without having been exercised in full, or is surrendered pursuant to an
Option Exchange Program, the unpurchased Shares that were subject thereto shall,
unless the Plan shall have been terminated, become available for future grant
under the Plan. In addition, any Shares of Common Stock that are retained by the
Company upon exercise of an Option or Stock Purchase Right in order to satisfy
the exercise or purchase price for such Option or Stock Purchase Right or any
withholding taxes due with respect to such exercise shall be treated as not
issued and shall continue to be available under the Plan. Shares issued under
the Plan and later repurchased by the Company pursuant to any repurchase right
that the Company may have shall not be available for future grant under the
Plan.

    4. ADMINISTRATION OF THE PLAN.

    (a) GENERAL. The Plan shall be administered by the Board or a Committee, or
a combination thereof, as determined by the Board. The Plan may be administered
by different administrative bodies with respect to different classes of
Optionees and, if permitted by the Applicable Laws, the Board may authorize one
or more officers to grant Options or Stock Purchase Rights under the Plan.

    (b) ADMINISTRATION WITH RESPECT TO REPORTING PERSONS. With respect to
Options granted to Reporting Persons and Named Executives, the Plan may (but
need not) be administered so as to permit such Options to qualify for the
exemption set forth in Rule 16b-3 and to qualify as performance-based
compensation under Section 162(m) of the Code.

    (c) COMMITTEE COMPOSITION. If a Committee has been appointed pursuant to
this Section 4, such Committee shall continue to serve in its designated
capacity until otherwise directed by the Board. From time to time the Board may
increase the size of any Committee and appoint additional members thereof,
remove members (with or without cause) and appoint new members in substitution
therefor, fill vacancies (however caused) and remove all members of a Committee
and thereafter directly administer the Plan, all to the extent permitted by the
Applicable Laws and, in the case of a Committee administering the Plan pursuant
to Section 4(b) above, to the extent permitted or required by Rule 16b-3 and
Section 162(m) of the Code.

    (d) 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, including
the approval, if required, of any Stock Exchange, the Administrator shall have
the authority, in its discretion:

    (i) to determine the Fair Market Value of the Common Stock, in accordance
with Section 2 (p) of the Plan;

    (ii) to select the Consultants and Employees to whom Options and Stock
Purchase Rights or any combination thereof may from time to time be granted;

<PAGE>

    (iii) to determine whether and to what extent Options and Stock Purchase
Rights or any combination thereof are granted;

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

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

    (vi) to determine the terms and conditions, not inconsistent with the terms
of the Plan, of any award granted hereunder, which terms and conditions include
but are not limited to the exercise or purchase 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, Optioned
Stock, Stock Purchase Right or Restricted Stock, based in each case on such
factors as the Administrator, in its sole discretion, shall determine;

    (vii) to determine whether and under what circumstances an Option may be
settled in cash under Section 9(f) instead of Common Stock;

    (viii) 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
shall have declined since the date the Option was granted and to make any other
amendments or adjustments to any Option that the Administrator determines, in
its discretion and under the authority granted to it under the Plan, to be
necessary or advisable, provided however that no amendment or adjustment to an
Option that would materially and adversely affect the rights of any Optionee
shall be made without the prior written consent of the Optionee;

    (ix) to determine the terms and restrictions applicable to Stock Purchase
Rights and the Restricted Stock purchased by exercising such Stock Purchase
Rights;

    (x) to initiate an Option Exchange Program;

    (xi) to construe and interpret the terms of the Plan and awards granted
under the Plan; and

    (xii) in order to fulfill the purposes of the Plan and without amending the
Plan, to modify grants of Options or Stock Purchase Rights to Participants who
are foreign nationals or employed outside of the United States in order to
recognize differences in local law, tax policies or customs.

    (e) EFFECT OF ADMINISTRATOR'S DECISION. All decisions, determinations and
interpretations of the Administrator shall be final and binding on all
Participants.

    5. ELIGIBILITY.

    (a) RECIPIENTS OF GRANTS. Nonstatutory Stock Options and Stock Purchase
Rights may be granted to Employees and Consultants. Incentive Stock Options may
be granted only to Employees; provided however that Employees of Affiliates
shall not be eligible to receive Incentive Stock Options. An Employee or
Consultant who has been granted an Option or Stock Purchase Right may, if he or
she is otherwise eligible, be granted additional Options or Stock Purchase
Rights.

    (b) TYPE OF OPTION. Each Option shall be designated in the Option Agreement
as either an Incentive Stock Option or a Nonstatutory Stock Option. However,
notwithstanding such designations, to the extent that the

<PAGE>

aggregate Fair Market Value of Shares with respect to which Options designated
as Incentive Stock Options are exercisable for the first time by any Optionee
during any calendar year (under all plans of the Company or any Parent or
Subsidiary) exceeds $100,000, such excess 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, and
the Fair Market Value of the Shares subject to an Incentive Stock Option shall
be determined as of the date of grant of such Option.

    (c) AT-WILL RELATIONSHIP. The Plan shall not confer upon any Participant any
right with respect to continuation of employment or consulting relationship with
the Company, nor shall it interfere in any way with such holder's right or the
Company's right to terminate his or her employment or consulting 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 years unless sooner
terminated under Section 15 of the Plan.

    7. TERM OF OPTION. The term of each Option shall be the term stated in the
Option Agreement; provided, however, that the term shall be no more than ten
years from the date of grant thereof or such shorter term as may be provided in
the Option Agreement. However, in the case of an Incentive Stock Option granted
to an Optionee who, at the time the Option is granted, is a Ten Percent Holder,
the term of such Option shall be five years from the date of grant thereof 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 pursuant to
exercise of an Option shall be such price as is determined by the Administrator
and set forth in the Option Agreement, but shall be subject to the following:

    (i) In the case of an Incentive Stock Option that is:

    (A) granted to an Employee who at the time of grant is a Ten Percent Holder,
the per Share 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 that is:

    (A) granted prior to the date, if any, on which the Common Stock becomes a
Listed Security to a person who at the time of grant is a Ten Percent Holder,
the per Share exercise price shall be no less than 110% of the Fair Market Value
per Share on the date of the grant if required by the Applicable Laws and, if
not so required, shall be such price as is determined by the Administrator.

    (B) granted prior to the date, if any, on which the Common Stock becomes a
Listed Security to any other eligible person, the per Share exercise price shall
be no less than 85% of the Fair Market Value per Share on the date of grant if
required by the Applicable Laws and, if not so required, shall be such price as
is determined by the Administrator.

<PAGE>

    (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) and may consist entirely of (1) cash; (2)
check; (3) delivery of Optionee's promissory note with such recourse, interest,
security and redemption provisions as the Administrator determines to be
appropriate (subject to the provisions of Section 153 of the Delaware General
Corporation Law); (4) cancellation of indebtedness; (5) other Shares that (x) in
the case of Shares acquired upon exercise of an Option, either have been owned
by the Optionee for more than six months on the date of surrender or such other
period as may be required to avoid a charge to the Company's earnings or were
not acquired, directly or indirectly, from the Company, 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; (6) authorization for the
Company to retain from the total number of Shares as to which the Option is
exercised that number of Shares having a Fair Market Value on the date of
exercise equal to the exercise price for the total number of Shares as to which
the Option is exercised; (7) delivery of a properly executed exercise notice
together with such other documentation as the Administrator and the broker, if
applicable, shall require to effect exercise of the Option and prompt delivery
to the Company of the sale or loan proceeds required to pay the exercise price
and any applicable withholding taxes; (8) any combination of the foregoing
methods of payment; or (9) such other consideration and method of payment for
the issuance of Shares to the extent permitted under the Applicable Laws. 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, and the Administrator may refuse to
accept a particular form of consideration at the time of any Option exercise if,
in its sole discretion, acceptance of such form of consideration is not in the
best interests of the Company at such time.

    9. EXERCISE OF OPTION.

    (a) PROCEDURE FOR EXERCISE; RIGHTS AS A STOCKHOLDER. Any Option granted
hereunder shall be exercisable at such times and under such conditions as
determined by the Administrator, consistent with the term of the Plan and
reflected in the Option Agreement, including vesting requirements and/or
performance criteria with respect to the Company and/or the Optionee; provided
however, that, if required by the Applicable Laws, any Option granted prior to
the date, if any, upon which the Common Stock becomes a Listed Security shall
become exercisable at the rate of at least 20% per year over five years from the
date the Option is granted. In the event that any of the Shares issued upon
exercise of an Option (which exercise occurs prior to the date, if any, upon
which the Common Stock becomes a Listed Security) should be subject to a right
of repurchase in the Company's favor, such repurchase right shall, if required
by the Applicable Laws, lapse at the rate of at least 20% per year over five
years from the date the Option is granted. Notwithstanding the above, in the
case of an Option granted to an officer, Director or Consultant of the Company
or any Parent, Subsidiary or Affiliate of the Company, the Option may become
fully exercisable, or a repurchase right, if any, in favor of the Company shall
lapse, at any time or during any period established by the Administrator. The
Administrator shall have the discretion to determine whether and to what extent
the vesting of Options shall cease or continue during any unpaid leave of
absence; provided however that in the absence of such determination, vesting of
Options shall cease during any such leave.

    An Option may not be exercised for a fraction of a Share.

    An Option shall be deemed exercised when written notice of such exercise has
been given to the Company in accordance with the terms of the Option by the
person entitled to exercise the Option and the Company has received full payment
for the Shares with respect to which the Option is exercised. Full payment may,
as authorized by the Administrator, consist of any consideration and method of
payment allowable under Section 8(b) of the Plan. Until the issuance (as
evidenced by the appropriate entry on the books of the Company or of a duly
authorized transfer agent of the Company) of the stock certificate evidencing
such Shares, no right to vote or receive dividends or any other rights as a
stockholder shall exist with respect to the Optioned Stock, not withstanding the
exercise of the Option. The Company shall issue (or cause to be issued) such
stock certificate promptly upon exercise of the Option.

<PAGE>

No adjustment will be made for a dividend or other right for which the record
date is prior to the date the stock certificate is 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 that thereafter may be 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 EMPLOYMENT OR CONSULTING RELATIONSHIP. In the event of
termination of an Optionee's Continuous Service Status with the Company, such
Optionee may, but only within three months (or such other period of time, not
less than 30 days, as is determined by the Administrator, with such
determination in the case of an Incentive Stock Option being made at the time of
grant of the Option) after the date of such termination (but in no event later
than the expiration date of the term of such Option as set forth in the Option
Agreement), exercise his or her Option to the extent that the Optionee was
entitled to exercise it at the date of such termination. To the extent that the
Optionee was not entitled to exercise the Option at the date of such
termination, or if the Optionee does not exercise the Option to the extent so
entitled within the time specified above, the Option shall terminate and the
Optioned Stock underlying the unexercised portion of the Option shall revert to
the Plan. Unless otherwise determined by the Administrator, no termination shall
be deemed to occur and this Section 9(b) shall not apply if (i) the Optionee is
a Consultant who becomes an Employee, or (ii) the Optionee is an Employee who
becomes a Consultant.

    (c) DISABILITY OF OPTIONEE.

    (i) Notwithstanding Section 9(b) above, in the event of termination of an
Optionee's Continuous Service Status as a result of his or her total and
permanent disability (within the meaning of Section 22(e)(3) of the Code), such
Optionee may, but only within twelve months (or such other period of time as is
determined by the Administrator, with such determination in the case of an
Incentive Stock Option made at the time of grant of the Option) from the date of
such termination (but in no event later than the expiration date of the term of
such Option as set forth in the Option Agreement), exercise the Option to the
extent otherwise entitled to exercise it at the date of such termination. To the
extent that the Optionee was not entitled to exercise the Option at the date of
termination, or if the Optionee does not exercise such Option to the extent so
entitled within the time specified above, the Option shall terminate and the
Optioned Stock underlying the unexercised portion of the Option shall revert to
the Plan.

    (ii) In the event of termination of an Optionee's Continuous Service Status
as a result of a disability which does not fall within the meaning of total and
permanent disability (as set forth in Section 22(e)(3) of the Code), such
Optionee may, but only within twelve months (or such other period of time as is
determined by the Administrator, with such determination in the case of an
Incentive Stock Option made at the time of grant of the Option) from the date of
such termination (but in no event later than the expiration date of the term of
such Option as set forth in the Option Agreement), exercise the Option to the
extent otherwise entitled to exercise it at the date of such termination.
However, to the extent that such Optionee fails to exercise an Option that is an
Incentive Stock Option (within the meaning of Section 422 of the Code) within
three months of the date of such termination, the Option will not qualify for
Incentive Stock Option treatment under the Code. To the extent that the Optionee
was not entitled to exercise the Option at the date of termination, or if the
Optionee does not exercise such Option to the extent so entitled within the time
period specified above, the Option shall terminate and the Optioned Stock
underlying the unexercised portion of the Option shall revert to the Plan.

    (d) DEATH OF OPTIONEE. In the event of the death of an Optionee during the
period of Continuous Service Status since the date of grant of the Option, or
within 30 days following termination of the Optionee's Continuous Service
Status, the Option may be exercised, at any time within twelve months following
the date of death (but in no event later than the expiration date of the term of
such Option as set forth in the Option Agreement), by such Optionee's estate or
by a person who acquired the right to exercise the Option by bequest or
inheritance, but only to the extent of the right to exercise that had accrued at
the date of death or, if earlier, the date of termination of the Optionee's
Continuous Service Status. To the extent that the Optionee was not entitled to
exercise the Option at the date of

<PAGE>

death or termination, as the case may be, or if the Optionee does not exercise
such Option to the extent so entitled within the time specified above, the
Option shall terminate and the Optioned Stock underlying the unexercised portion
of the Option shall revert to the Plan.

    (e) EXTENSION OF EXERCISE PERIOD. The Administrator shall have full power
and authority to extend the period of time for which an Option is to remain
exercisable following termination of an Optionee's Continuous Status as an
Employee or Consultant from the periods set forth in Sections 9(b), 9(c) and
9(d) above or in the Option Agreement to such greater time as the Board shall
deem appropriate, provided, that in no event shall such Option be exercisable
later than the date of expiration of the term of such Option as set forth in the
Option Agreement.

    (f) BUY-OUT PROVISIONS. The Administrator may at any time offer to buy out
for a payment in cash or Shares an Option previously granted under the Plan
based on such terms and conditions as the Administrator shall establish and
communicate to the Optionee at the time such offer is made.

    10. 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 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, which shall in no event exceed 30 days from the date upon which the
Administrator made the determination to grant the Stock Purchase Right. If
required by the Applicable Laws, the purchase price of Shares subject to Stock
Purchase Rights shall not be less than 85% of the Fair Market Value of the
Shares as of the date of the offer, or, in the case of a person owning stock
representing more than 10% of the total combined voting power of all classes of
stock of the Company or any Parent or Subsidiary, the price shall not be less
than 100% of the Fair Market Value of the Shares as of the date of the offer. If
the Applicable Laws do not impose restrictions on the purchase price, the
purchase price of Shares subject to Stock Purchase Rights shall be as determined
by the Administrator. The offer to purchase Shares subject to Stock Purchase
Rights 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
employment 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 purchase 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;
provided, however, that with respect to a purchaser who is not an officer,
Director or Consultant of the Company or of any Parent or Subsidiary of the
Company, it shall lapse at a minimum rate of 20% per year if required by the
Applicable Laws.

    (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. In addition, the
provisions of Restricted Stock Purchase Agreements need not be the same with
respect to each purchaser.

    (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 12 of the Plan.

<PAGE>

    11. TAXES.

    (a) As a condition of the exercise of an Option or Stock Purchase Right
granted under the Plan, the Participant (or in the case of the Participant's
death, the person exercising the Option) shall make such arrangements as the
Administrator may require for the satisfaction of any applicable federal, state,
local or foreign withholding tax obligations that may arise in connection with
the exercise of an Option or Stock Purchase Right and the issuance of Shares.
The Company shall not be required to issue any Shares under the Plan until such
obligations are satisfied.

    (b) In the case of an Employee and in the absence of any other arrangement,
the Employee shall be deemed to have directed the Company to withhold or collect
from his or her compensation an amount sufficient to satisfy such tax
obligations from the next payroll payment otherwise payable after the date of an
exercise of the Option.

    (c) This Section 11(c) shall apply only after the date, if any, upon which
the Common Stock becomes a Listed Security. In the case of a Participant other
than an Employee (or in the case of an Employee where the next payroll payment
is not sufficient to satisfy such tax obligations, with respect to any remaining
tax obligations), in the absence of any other arrangement and to the extent
permitted under the Applicable Laws, the Participant shall be deemed to have
elected to have the Company withhold from the Shares to be issued upon exercise
of the Option or Stock Purchase Right that number of Shares having a Fair Market
Value determined as of the applicable Tax Date (as defined below) equal to the
amount required to be withheld. For purposes of this Section 11, 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 under the Applicable Laws (the
"Tax Date").

    (d) If permitted by the Administrator, in its discretion, a Participant may
satisfy his or her tax withholding obligations upon exercise of an Option or
Stock Purchase Right by surrendering to the Company Shares that (i) in the case
of Shares previously acquired from the Company, have been owned by the
Participant for more than six months on the date of surrender, and (ii) have a
Fair Market Value determined as of the applicable Tax Date equal to the amount
required to be withheld.

    (e) Any election or deemed election by a Participant to have Shares withheld
to satisfy tax withholding obligations under Section 11(c) or (d) above shall be
irrevocable as to the particular Shares as to which the election is made and
shall be subject to the consent or disapproval of the Administrator. Any
election by a Participant under Section 11(d) above must be made on or prior to
the applicable Tax Date.

    (f) In the event an election to have Shares withheld is made by a
Participant and the Tax Date is deferred under Section 83 of the Code because no
election is filed under Section 83(b) of the Code, the Participant shall receive
the full number of Shares with respect to which the Option or Stock Purchase
Right is exercised but such Participant shall be unconditionally obligated to
tender back to the Company the proper number of Shares on the Tax Date.

    12. NON-TRANSFERABILITY OF OPTIONS AND STOCK PURCHASE RIGHTS. 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; provided however that, after the date, if any, upon
which the Common Stock becomes a Listed Security, the Administrator may in its
discretion grant transferable Nonstatutory Stock Options pursuant to Option
Agreements specifying (i) the manner in which such Nonstatutory Stock Options
are transferable and (ii) that any such transfer shall be subject to the
Applicable Laws. The designation of a beneficiary by an Optionee will not
constitute a transfer. An Option or Stock Purchase Right may be exercised,
during the lifetime of the holder of the Option or Stock Purchase Right, only by
such holder or a transferee permitted by this Section 12.

<PAGE>

    13. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, CORPORATE TRANSACTIONS AND
CERTAIN OTHER TRANSACTIONS.

    (a) CHANGES IN CAPITALIZATION. Subject to any required action by the
stockholders of the Company, the number of shares of Common Stock covered by
each outstanding Option or Stock Purchase Right, and 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 that 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, recapitalization or reclassification of the Common Stock (including
any change in the number of Shares of Common Stock effected in connection with a
change of domicile of the Company), 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
Administrator, 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 dissolution or
liquidation of the Company, each outstanding Option or Stock Purchase Right
shall terminate immediately prior to the consummation of such action, unless
otherwise provided by the Administrator.

    (c) CORPORATE TRANSACTIONS; CHANGE OF CONTROL. In the event of a Corporate
Transaction, each outstanding Option and Stock Purchase Right shall be assumed
or an equivalent option or right shall be substituted by the successor
corporation or a Parent or Subsidiary of such successor corporation, unless such
successor corporation does not agree to assume the outstanding Options or Stock
Purchase Rights or to substitute equivalent options or rights, in which case
such Options or Stock Purchase Rights shall terminate upon the consummation of
the transaction; provided however that in the event of a Change of Control, the
Administrator shall, as to outstanding Options, either (i) provide that such
Options shall be assumed by the successor corporation or a Parent or Subsidiary
of the successor corporation (such entity, the "Successor Corporation") or that
the Successor Corporation shall substitute with respect to such Options
equivalent options; (ii) provide upon notice to Optionees that all Options, to
the extent then exercisable or to be exercisable as a result of the Change of
Control, must be exercised on or before a specified date (which date shall be at
least five (5) days from the date of the notice), after which the Options shall
terminate; or (iii) terminate each Option in its entirety in exchange for a
payment of cash, securities and/or other property equal to the excess of the
Fair Market Value of the portion of the Optioned Stock that is vested and
exercisable immediately prior to the consummation of the transaction over the
aggregate exercise price thereof.

    For purposes of this Section 13(c), an Option or a Stock Purchase Right
shall be considered assumed, without limitation, if, at the time of issuance of
the stock or other consideration upon a Corporate Transaction or a Change of
Control, as the case may be, each holder of an Option or Stock Purchase Right
would be entitled to receive upon exercise of the Option or Stock Purchase Right
the same number and kind of shares of stock or the same amount of property, cash
or securities as such holder would have been entitled to receive upon the
occurrence of the transaction if the holder had been, immediately prior to such
transaction, the holder of the number of Shares of Common Stock covered by the
Option or the Stock Purchase Right at such time (after giving effect to any
adjustments in the number of Shares covered by the Option or Stock Purchase
Right as provided for in this Section 13); provided however that if such
consideration received in the transaction 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
exercise of the Option or Stock Purchase Right to be solely common stock of the
successor corporation or its Parent equal to the Fair Market Value of the per
Share consideration received by holders of Common Stock in the transaction.

<PAGE>

    (d) CERTAIN DISTRIBUTIONS. In the event of any distribution to the Company's
stockholders of securities of any other entity or other assets (other than
dividends payable in cash or stock of the Company) without receipt of
consideration by the Company, the Administrator may, in its discretion,
appropriately adjust the price per Share of Common Stock covered by each
outstanding Option or Stock Purchase Right to reflect the effect of such
distribution.

    14. 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; provided,
however, that in the case of any Incentive Stock Option, the grant date shall be
the later of the date on which the Administrator makes the determination
granting such Incentive Stock Option or the date of commencement of the
Optionee's employment relationship with the Company. Notice of the determination
shall be given to each Employee or Consultant to whom an Option or Stock
Purchase Right is so granted within a reasonable time after the date of such
grant.

    15. AMENDMENT AND TERMINATION OF THE PLAN.

    (a) AUTHORITY TO AMEND OR TERMINATE. The Board may at any time amend, alter,
suspend, discontinue or terminate the Plan, but no amendment, alteration,
suspension, discontinuation or termination (other than an adjustment made
pursuant to Section 13 above) shall be made that would materially and adversely
affect the rights of any Optionee or holder of Stock Purchase Rights under any
outstanding grant, without his or her consent. In addition, to the extent
necessary and desirable to comply with the Applicable Laws, the Company shall
obtain stockholder approval of any Plan amendment in such a manner and to such a
degree as required.

    (b) EFFECT OF AMENDMENT OR TERMINATION. No amendment or termination of the
Plan shall materially and adversely affect Options already granted, unless
mutually agreed otherwise between the Optionee and the Administrator, which
agreement must be in writing and signed by the Optionee and the Company.

    16. CONDITIONS UPON ISSUANCE OF SHARES. Notwithstanding any other provision
of the Plan or any agreement entered into by the Company pursuant to the Plan,
the Company shall not be obligated, and shall have no liability for, failure to
issue or deliver any Shares under the Plan unless such issuance or delivery
would comply with the Applicable Laws, with such compliance determined by the
Company in consultation with its legal counsel.

    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 by law.

    17. 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.

    18. AGREEMENTS. Options and Stock Purchase Rights shall be evidenced by
Option Agreements and Restricted Stock Purchase Agreements, respectively, in
such form(s) as the Administrator shall from time to time approve.

    19. STOCKHOLDER APPROVAL. If required by the Applicable Laws, continuance of
the Plan shall be subject to approval by the stockholders of the Company within
twelve months before or after the date the Plan is adopted. Such stockholder
approval shall be obtained in the degree and manner required under the
Applicable Laws.

    20. INFORMATION AND DOCUMENTS TO OPTIONEES AND PURCHASERS. Prior to the
date, if any, upon which the Common Stock becomes a Listed Security and if
required by the Applicable Laws, the Company shall provide

<PAGE>

financial statements at least annually to each Optionee and to each individual
who acquired Shares pursuant to the Plan, 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 acquired Shares pursuant to the Plan, during the
period such individual owns such Shares. The Company shall not be required to
provide such information if the issuance of Options or Stock Purchase Rights
under the Plan is limited to key employees whose duties in connection with the
Company assure their access to equivalent information. In addition, at the time
of issuance of any securities under the Plan, the Company shall provide to the
Optionee or the purchaser a copy of the Plan and any agreement(s) pursuant to
which securities granted under the Plan are issued.<PAGE>

provisions of Section 13 of the Plan, the maximum aggregate number of Shares
which may be issued upon exercise of such Options or Stock Purchase Rights is

Rights may be authorized but unissued, or reacquired Common Stock. If an Option
or Stock Purchase Right expires or becomes unexercisable without having been
exercised in full, the unpurchased Shares which were subject thereto shall
become available for future grant or sale under the Plan (unless the Plan has
terminated). Shares which are delivered by the Holder or withheld by the Company
upon the exercise of an Option or Stock Purchase Right under the Plan, in
payment of the exercise price thereof or tax withholding thereon, may again be
optioned, granted or awarded hereunder, subject to the limitations of this
Section 3. 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. Notwithstanding the provisions of this Section 3, no Shares may
again be optioned, granted or awarded if such action would cause an Incentive
Stock Option to fail to qualify as an Incentive Stock Option under Code Section
422.

    4. ADMINISTRATION OF THE PLAN.

    (a) Administrator. Unless and until the Board delegates administration to a
Committee as set forth below, the Plan shall be administered by the Board. The
Board may delegate administration of the Plan to a Committee or Committees of
one or more members of the Board, and the term "Committee" shall apply to any
person or persons to whom such authority has been delegated. If administration
is delegated to a Committee, the Committee shall have, in connection with the
administration of the Plan, the powers theretofore possessed by the Board,
including the power to delegate to a subcommittee any of the administrative
powers the Committee is authorized to exercise (and references in this Plan to
the Board shall thereafter be to the Committee or subcommittee), subject,
however, to such resolutions, not inconsistent with the provisions of the Plan,
as may be adopted from time to time by the Board. Notwithstanding the foregoing,
however, from and after the Public Trading Date, a Committee of the Board shall
administer the Plan and the Committee shall consist solely of two or more
Independent Directors each of whom is both an "outside director," within the
meaning of Section 162(m) of the Code, and a "non-employee director" within the
meaning of Rule 16b-3. Within the scope of such authority, the Board or the
Committee may (i) delegate to a committee of one or more members of the Board
who are not Independent Directors the authority to grant awards under the Plan
to eligible persons who are either (1) not then "covered employees," within the
meaning of Section 162(m) of the Code and are not expected to be "covered
employees" at the time of recognition of income resulting from such award or (2)
not persons with respect to whom the Company wishes to comply with Section
162(m) of the Code and/or (ii) delegate to a committee of one or more members of
the Board who are not "non-employee directors," within the meaning of Rule
16b-3, the authority to grant awards under the Plan to eligible persons who are
not then subject to Section 16 of the Exchange Act. The Board may abolish the
Committee at any time and revest in the Board the administration of the Plan.
Appointment of Committee members shall be effective upon acceptance of
appointment. Committee members may resign at any time by delivering written
notice to the Board. Vacancies in the Committee may only be filled by the Board.

    (b) Powers of the Administrator. Subject to the provisions of the Plan and
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 sole discretion:

    (i) to determine the Fair Market Value;

<PAGE>

    (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 vest or 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 to offer to buyout a previously granted Option as
provided in subsection 10(i) and to determine the terms and conditions of such
offer and buyout (including whether payment is to be made in cash or Shares);

    (vii) 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;

    (viii) to allow Holders 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 based on the statutory
withholding rates for federal and state tax purposes that apply to supplemental
taxable income. 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 Holders 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;

    (ix) to amend the Plan or any Option or Stock Purchase Right granted under
the Plan as provided in Section 15; and

    (x) to construe and interpret the terms of the Plan and awards granted
pursuant to the Plan and to exercise such powers and perform such acts as the
Administrator deems necessary or desirable to promote the best interests of the
Company which are not in conflict with the provisions of the Plan.

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

    5. ELIGIBILITY. Non-Qualified Stock Options and Stock Purchase Rights may be
granted to Service Providers. Incentive Stock Options may be granted only to
Employees. If otherwise eligible, an Employee or Consultant who has been granted
an Option or Stock Purchase Right may be granted additional Options or Stock
Purchase Rights.

    6. LIMITATIONS.

    (a) Each Option shall be designated by the Administrator in the Option
Agreement as either an Incentive Stock Option or a Non-Qualified Stock Option.
However, notwithstanding such designations, to the extent that the aggregate
Fair Market Value of Shares subject to a Holder's Incentive Stock Options and
other incentive stock options granted by the Company, any Parent or Subsidiary,
which become exercisable for the first time during any calendar year (under all
plans of the Company or any Parent or Subsidiary) exceeds $100,000, such excess
Options

<PAGE>

or other options shall be treated as Non-Qualified 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, and the Fair Market Value
of the Shares shall be determined as of the time of grant.

    (b) Neither the Plan, any Option nor any Stock Purchase Right shall confer
upon a Holder any right with respect to continuing the Holder's employment or
consulting relationship with the Company, nor shall they interfere in any way
with the Holder's right or the Company's right to terminate such employment or
consulting relationship at any time, with or without cause.

    (c) No Service Provider shall be granted, in any calendar year, Options or
Stock Purchase Rights to purchase more than 10,000,000 Shares; provided,
however, that the foregoing limitation shall not apply prior to the Public
Trading Date and, following the Public Trading Date, the foregoing limitation
shall not apply until the earliest of: (i) the first material modification of
the Plan (including any increase in the number of shares reserved for issuance
under the Plan in accordance with Section 3); (ii) the issuance of all of the
shares of Common Stock reserved for issuance under the Plan; (iii) the
expiration of the Plan; (iv) the first meeting of stockholders at which
Directors of the Company are to be elected that occurs after the close of the
third calendar year following the calendar year in which occurred the first
registration of an equity security of the Company under Section 12 of the
Exchange Act; or (v) such other date required by Section 162(m) of the Code and
the rules and regulations promulgated thereunder. The foregoing limitation shall
be adjusted proportionately in connection with any change in the Company's
capitalization as described in Section 13. For purposes of this Section 6(c), if
an Option is canceled in the same calendar year it was granted (other than in
connection with a transaction described in Section 15), the canceled Option will
be counted against the limit set forth in this Section 6(c). For this purpose,
if the exercise price of an Option is reduced, the transaction shall be treated
as a cancellation of the Option and the grant of a new Option.

    7. TERM OF PLAN. The Plan shall become effective upon its initial adoption
by the Board and shall continue in effect until it is terminated under Section
17 of the Plan. No Options or Stock Purchase Rights may be issued under the Plan
after the tenth (10th) anniversary of the earlier of (i) the date upon which the
Plan is adopted by the Board or (ii) the date the Plan is approved by the
stockholders.

    8. 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 a Holder who, at the time the Option is granted, owns (or is treated as
owning under Code Section 424) 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.

    9. OPTION EXERCISE PRICE AND CONSIDERATION.

    (a) Except as provided in Section 13, 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:

    (i) In the case of an Incentive Stock Option

    (A) granted to an Employee who, at the time of grant of such Option, owns
(or is treated as owning under Code Section 424) 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 one
hundred ten percent (110%) of the Fair Market Value per Share on the date of
grant.

<PAGE>

    (B) granted to any other Employee, the per Share exercise price shall be no
less than one hundred percent (100%) of the Fair Market Value per Share on the
date of grant.

    (ii) In the case of a Non-Qualified 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 one hundred ten percent (110%) of the Fair Market Value
per Share on the date of the grant.

    (B) granted to any other Service Provider, the per Share exercise price
shall be no less than eighty-five percent (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) with the consent of the Administrator, a full recourse promissory
note bearing interest (at a market rate of interest) and payable upon such terms
as may be prescribed by the Administrator, (4) with the consent of the
Administrator, other Shares which (x) in the case of Shares acquired from the
Company, have been owned by the Holder for more than six (6) 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) with the consent of the Administrator, surrendered Shares then
issuable upon exercise of the Option having a Fair Market Value on the date of
exercise equal to the aggregate exercise price of the Option or exercised
portion thereof, (6) property of any kind which constitutes good and valuable
consideration, (7) with the consent of the Administrator, delivery of a notice
that the Holder has placed a market sell order with a broker with respect to
Shares then issuable upon exercise of the Options and that the broker has been
directed to pay a sufficient portion of the net proceeds of the sale to the
Company in satisfaction of the Option exercise price, provided, that payment of
such proceeds is then made to the Company upon settlement of such sale, or (8)
with the consent of the Administrator, any combination of the foregoing methods
of payment.

    10. EXERCISE OF OPTION.

    (a) Vesting; Fractional Exercises. Except as provided in Section 13, Options
granted hereunder shall be vested and 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; provided, however, that, prior to the Public
Trading Date, except with regard to Options granted to Officers, Directors or
Consultants, in no event shall an Option granted hereunder become vested and
exercisable at a rate of less than twenty percent (20%) per year over five (5)
years from the date the Option is granted, subject to reasonable conditions,
such as continuing to be a Service Provider. An Option may not be exercised for
a fraction of a Share.

    (b) Deliveries upon Exercise. All or a portion of an exercisable Option
shall be deemed exercised upon delivery of all of the following to the Secretary
of the Company or his or her office:

<PAGE>

    (i) A written or electronic notice complying with the applicable rules
established by the Administrator stating that the Option, or a portion thereof,
is exercised. The notice shall be signed by the Holder or other person then
entitled to exercise the Option or such portion of the Option;

    (ii) Such representations and documents as the Administrator, in its sole
discretion, deems necessary or advisable to effect compliance with Applicable
Laws. The Administrator may, in its sole discretion, also take whatever
additional actions it deems appropriate to effect such compliance, including,
without limitation, placing legends on share certificates and issuing stop
transfer notices to agents and registrars;

    (iii) Upon the exercise of all or a portion of an unvested Option pursuant
to Section 10(h), a Restricted Stock purchase agreement in a form determined by
the Administrator and signed by the Holder or other person then entitled to
exercise the Option or such portion of the Option; and

    (iv) In the event that the Option shall be exercised pursuant to Section
10(f) by any person or persons other than the Holder, appropriate proof of the
right of such person or persons to exercise the Option.

    (c) Conditions to Delivery of Share Certificates. The Company shall not be
required to issue or deliver any certificate or certificates for Shares
purchased upon the exercise of any Option or portion thereof prior to
fulfillment of all of the following conditions:

    (i) The admission of such Shares to listing on all stock exchanges on which
such class of stock is then listed;

    (ii) The completion of any registration or other qualification of such
Shares under any state or federal law, or under the rulings or regulations of
the Securities and Exchange Commission or any other governmental regulatory body
which the Administrator shall, in its sole discretion, deem necessary or
advisable;

    (iii) The obtaining of any approval or other clearance from any state or
federal governmental agency which the Administrator shall, in its sole
discretion, determine to be necessary or advisable;

    (iv) The lapse of such reasonable period of time following the exercise of
the Option as the Administrator may establish from time to time for reasons of
administrative convenience; and

    (v) The receipt by the Company of full payment for such Shares, including
payment of any applicable withholding tax, which in the sole discretion of the
Administrator may be in the form of consideration used by the Holder to pay for
such Shares under Section 9(b).

    (d) Termination of Relationship as a Service Provider. If a Holder ceases to
be a Service Provider other than by reason of the Holder's disability or death,
such Holder 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; provided, however, that prior to the Public Trading Date,
such period of time shall not be less than thirty (30) days (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 Holder's
termination. If, on the date of termination, the Holder is not vested as to his
or her entire Option, the Shares covered by the unvested portion of the Option
immediately cease to be issuable under the Option and shall again become
available for issuance under the Plan. If, after termination, the Holder does
not exercise his or her Option within the time period specified herein, the
Option shall terminate, and the Shares covered by such Option shall again become
available for issuance under the Plan.

<PAGE>

    (e) Disability of Holder. If a Holder ceases to be a Service Provider as a
result of the Holder's disability, the Holder 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; provided, however, that prior
to the Public Trading Date, such period of time shall not be less than six (6)
months (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 Holder's termination. If such disability is not a "disability" as
such term is defined in Section 22(e)(3) of the Code, in the case of an
Incentive Stock Option such Incentive Stock Option shall automatically cease to
be treated as an Incentive Stock Option and shall be treated for tax purposes as
a Non-Qualified Stock Option from and after the day which is three (3) months
and one (1) day following such termination. If, on the date of termination, the
Holder is not vested as to his or her entire Option, the Shares covered by the
unvested portion of the Option shall immediately cease to be issuable under the
Option and shall again become available for issuance under the Plan. If, after
termination, the Holder does not exercise his or her Option within the time
specified herein, the Option shall terminate, and the Shares covered by such
Option shall again become available for issuance under the Plan.

    (f) Death of Holder. If a Holder dies while a Service Provider, the Option
may be exercised within such period of time as is specified in the Option
Agreement provided, however, that prior to the Public Trading Date, such period
of time shall not be less than six (6) months (but in no event later than the
expiration of the term of such Option as set forth in the Notice of Grant), by
the Holder's estate or by a person who acquires the right to exercise the Option
by bequest or inheritance, but only to the extent that the Option is vested on
the date of death. In the absence of a specified time in the Option Agreement,
the Option shall remain exercisable for twelve (12) months following the
Holder's termination. If, at the time of death, the Holder is not vested as to
his or her entire Option, the Shares covered by the unvested portion of the
Option shall immediately cease to be issuable under the Option and shall again
become available for issuance under the Plan. The Option may be exercised by the
executor or administrator of the Holder's estate or, if none, by the person(s)
entitled to exercise the Option under the Holder's will or the laws of descent
or distribution. If the Option is not so exercised within the time specified
herein, the Option shall terminate, and the Shares covered by such Option shall
again become available for issuance under the Plan.

    (g) Regulatory Extension. A Holder's Option Agreement may provide that if
the exercise of the Option following the termination of the Holder's status as a
Service Provider (other than upon the Holder's death or Disability) would be
prohibited at any time solely because the issuance of shares would violate the
registration requirements under the Securities Act, then the Option shall
terminate on the earlier of (i) the expiration of the term of the Option set
forth in Section 8 or (ii) the expiration of a period of three (3) months after
the termination of the Holder's status as a Service Provider during which the
exercise of the Option would not be in violation of such registration
requirements.

    (h) Early Exercisability. The Administrator may provide in the terms of a
Holder's Option Agreement that the Holder may, at any time before the Holder's
status as a Service Provider terminates, exercise the Option in whole or in part
prior to the full vesting of the Option; provided, however, that subject to
Section 22, Shares acquired upon exercise of an Option which has not fully
vested may be subject to any forfeiture, transfer or other restrictions as the
Administrator may determine in its sole discretion.

    (i) Buyout Provisions. The Administrator may at any time offer to buyout 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
Holder at the time that such offer is made.

    11. NON-TRANSFERABILITY OF OPTIONS AND STOCK PURCHASE RIGHTS. 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 Holder,
only by the Holder.

<PAGE>

    12. STOCK PURCHASE RIGHTS.

    (a) Rights to Purchase. Stock Purchase Rights may be issued either alone, in
addition to, or in tandem with Options 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 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; provided,
however, that to the extent required to comply with applicable securities laws,
the purchase price of such Shares shall not be less than the purchase price
requirements set forth in 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 Right. Unless the Administrator determines otherwise, the
Restricted Stock purchase agreement shall grant the Company the right to
repurchase Shares acquired upon exercise of a Stock Purchase Right upon the
termination of the purchaser's status as a Service Provider for any reason.
Subject to Section 22, the purchase price for Shares repurchased by the Company
pursuant to such repurchase right and the rate at which such repurchase right
shall lapse shall be determined by the Administrator in its sole discretion, and
shall be set forth in the Restricted Stock purchase agreement.

    (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 15 of the Plan.

    13. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, MERGER OR ASSET SALE.

    (a) In the event that the Administrator determines that any dividend or
other distribution (whether in the form of cash, Common Stock, other securities,
or other property), recapitalization, reclassification, stock split, reverse
stock split, reorganization, merger, consolidation, split-up, spin-off,
combination, repurchase, liquidation, dissolution, or sale, transfer, exchange
or other disposition of all or substantially all of the assets of the Company,
or exchange of Common Stock or other securities of the Company, issuance of
warrants or other rights to purchase Common Stock or other securities of the
Company, or other similar corporate transaction or event, in the Administrator's
sole discretion, affects the Common Stock such that an adjustment is determined
by the Administrator to be appropriate in order to prevent dilution or
enlargement of the benefits or potential benefits intended by the Company to be
made available under the Plan or with respect to any Option, Stock Purchase
Right or Restricted Stock, then the Administrator shall, in such manner as it
may deem equitable, adjust any or all of:

    (i) the number and kind of shares of Common Stock (or other securities or
property) with respect to which Options or Stock Purchase Rights may be granted
or awarded (including, but not limited to, adjustments of the limitations in
Section 3 on the maximum number and kind of shares which may be issued and
adjustments of the maximum number of Shares that may be purchased by any Holder
in any calendar year pursuant to Section 6(c));

    (ii) the number and kind of shares of Common Stock (or other securities or
property) subject to outstanding Options, Stock Purchase Rights or Restricted
Stock; and

<PAGE>

    (iii) the grant or exercise price with respect to any Option or Stock
Purchase Right.

    (b) In the event of any transaction or event described in Section 15(a), the
Administrator, in its sole discretion, and on such terms and conditions as it
deems appropriate, either by the terms of the Option, Stock Purchase Right or
Restricted Stock or by action taken prior to the occurrence of such transaction
or event and either automatically or upon the Holder's request, is hereby
authorized to take any one or more of the following actions whenever the
Administrator determines that such action is appropriate in order to prevent
dilution or enlargement of the benefits or potential benefits intended by the
Company to be made available under the Plan or with respect to any Option, Stock
Purchase Right or Restricted Stock granted or issued under the Plan or to
facilitate such transaction or event:

    (i) To provide for either the purchase of any such Option, Stock Purchase
Right or Restricted Stock for an amount of cash equal to the amount that could
have been obtained upon the exercise of such Option or Stock Purchase Right or
realization of the Holder's rights had such Option, Stock Purchase Right or
Restricted Stock been currently exercisable or payable or fully vested or the
replacement of such Option, Stock Purchase Right or Restricted Stock with other
rights or property selected by the Administrator in its sole discretion;

    (ii) To provide that such Option or Stock Purchase Right shall be
exercisable as to all shares covered thereby, notwithstanding anything to the
contrary in the Plan or the provisions of such Option or Stock Purchase Right;

    (iii) To provide that such Option, Stock Purchase Right or Restricted Stock
be assumed by the successor or survivor corporation, or a parent or subsidiary
thereof, or shall be substituted for by similar options, rights or awards
covering the stock of the successor or survivor corporation, or a parent or
subsidiary thereof, with appropriate adjustments as to the number and kind of
shares and prices;

    (iv) To make adjustments in the number and type of shares of Common Stock
(or other securities or property) subject to outstanding Options and Stock
Purchase Rights, and/or in the terms and conditions of (including the grant or
exercise price), and the criteria included in, outstanding Options, Stock
Purchase Rights or Restricted Stock or Options, Stock Purchase Rights or
Restricted Stock which may be granted in the future; and

    (v) To provide that immediately upon the consummation of such event, such
Option or Stock Purchase Right shall not be exercisable and shall terminate;
provided, that for a specified period of time prior to such event, such Option
or Stock Purchase Right shall be exercisable as to all Shares covered thereby,
and the restrictions imposed under an Option Agreement or Restricted Stock
purchase agreement upon some or all Shares may be terminated and, in the case of
Restricted Stock, some or all shares of such Restricted Stock may cease to be
subject to repurchase, notwithstanding anything to the contrary in the Plan or
the provisions of such Option, Stock Purchase Right or Restricted Stock purchase
agreement.

    (c) Subject to Section 3, the Administrator may, in its sole discretion,
include such further provisions and limitations in any Option, Stock Purchase
Right, Restricted Stock agreement or certificate, as it may deem equitable and
in the best interests of the Company.

    (d) If the Company undergoes an Acquisition, then any surviving corporation
or entity or acquiring corporation or entity, or affiliate of such corporation
or entity, may assume any Options, Stock Purchase Rights or Restricted Stock
outstanding under the Plan or may substitute similar stock awards (including an
award to acquire the same consideration paid to the stockholders in the
transaction described in this subsection 15(d)) for those outstanding under the
Plan. In the event any surviving corporation or entity or acquiring corporation
or entity in an Acquisition, or affiliate of such corporation or entity, does
not assume such Options, Stock Purchase Rights or Restricted Stock or does not
substitute similar stock awards for those outstanding under the Plan, then with
respect to (i) Options, Stock Purchase Rights or Restricted Stock held by
participants in the Plan whose status as a Service Provider has not terminated
prior to such event, the vesting of such Options, Stock Purchase Rights or
Restricted Stock (and, if applicable, the time during which such awards may be
exercised) shall be accelerated and made fully exercisable and all restrictions
thereon shall lapse at least ten (10) days prior to the closing of the
Acquisition (and the Options

<PAGE>

or Stock Purchase Rights terminated if not exercised prior to the closing of
such Acquisition), and (ii) any other Options or Stock Purchase Rights
outstanding under the Plan, such Options or Stock Purchase rights shall be
terminated if not exercised prior to the closing of the Acquisition.

    (e) The existence of the Plan, any Option Agreement or Restricted Stock
purchase agreement and the Options or Stock Purchase Rights granted hereunder
shall not affect or restrict in any way the right or power of the Company or the
stockholders of the Company to make or authorize any adjustment,
recapitalization, reorganization or other change in the Company's capital
structure or its business, any merger or consolidation of the Company, any issue
of stock or of options, warrants or rights to purchase stock or of bonds,
debentures, preferred or prior preference stocks whose rights are superior to or
affect the Common Stock or the rights thereof or which are convertible into or
exchangeable for Common Stock, or the dissolution or liquidation of the Company,
or any sale or transfer of all or any part of its assets or business, or any
other corporate act or proceeding, whether of a similar character or otherwise.

    14. 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 Employee or Consultant to whom an Option or
Stock Purchase Right is so granted 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 wholly or partially
amend, alter, suspend or terminate the Plan. However, without approval of the
Company's stockholders given within twelve (12) months before or after the
action by the Board, no action of the Board may, except as provided in Section
15, increase the limits imposed in Section 3 on the maximum number of Shares
which may be issued under the Plan or extend the term of the Plan under Section
7.

    (b) Stockholder Approval. The Board 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 Holder, unless
mutually agreed otherwise between the Holder and the Administrator, which
agreement must be in writing and signed by the Holder 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, Stock Purchase
Rights or Restricted Stock granted or awarded under the Plan prior to the date
of such termination.

    16. STOCKHOLDER APPROVAL. The Plan will be submitted for the approval of the
Company's stockholders within twelve (12) months after the date of the Board's
initial adoption of the Plan. Options, Stock Purchase Rights or Restricted Stock
may be granted or awarded prior to such stockholder approval, provided that such
Options, Stock Purchase Rights and Restricted Stock shall not be exercisable,
shall not vest and the restrictions thereon shall not lapse prior to the time
when the Plan is approved by the stockholders, and provided further that if such
approval has not been obtained at the end of said twelve-month period, all
Options, Stock Purchase Rights and Restricted Stock previously granted or
awarded under the Plan shall thereupon be canceled and become null and void.

    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.

<PAGE>

    18. 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.

    19. INFORMATION TO HOLDERS AND PURCHASERS. Prior to the Public Trading Date
and to the extent required by Section 260.140.46 of Title 10 of the California
Code of Regulations, the Company shall provide to each Holder and to each
individual who acquires Shares pursuant to the Plan, not less frequently than
annually during the period such Holder 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. Notwithstanding the
preceding sentence, 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.

    20. REPURCHASE PROVISIONS. The Administrator in its sole discretion may
provide that the Company may repurchase Shares acquired upon exercise of an
Option or Stock Purchase Right upon the occurrence of certain specified events,
including, without limitation, a Holder's termination as a Service Provider,
divorce, bankruptcy or insolvency; provided, however, that any such repurchase
right shall be set forth in the applicable Option Agreement or Restricted Stock
purchase agreement or in another agreement referred to in such agreement and,
provided further, that to the extent required by Section 260.140.41 and Section
260.140.42 of Title 10 of the California Code of Regulations, any such
repurchase right set forth in an Option or Stock Purchase Right granted prior to
the Public Trading Date to a person who is not an Officer, Director or
Consultant shall be upon the following terms: (i) if the repurchase option gives
the Company the right to repurchase the shares upon termination as a Service
Provider at not less than the Fair Market Value of the shares to be purchased on
the date of termination of status as a Service Provider, then (A) the right to
repurchase shall be exercised for cash or cancellation of purchase money
indebtedness for the shares within ninety (90) days of termination of status as
a Service Provider (or in the case of shares issued upon exercise of Options or
Stock Purchase Rights after such date of termination, within ninety (90) days
after the date of the exercise) or such longer period as may be agreed to by the
Administrator and the Plan participant and (B) the right terminates when the
shares become publicly traded; and (ii) if the repurchase option gives the
Company the right to repurchase the Shares upon termination as a Service
Provider at the original purchase price for such Shares, then (A) the right to
repurchase at the original purchase price shall lapse at the rate of at least
twenty percent (20%) of the shares per year over five (5) years from the date
the Option or Stock Purchase Right is granted (without respect to the date the
Option or Stock Purchase Right was exercised or became exercisable) and (B) the
right to repurchase shall be exercised for cash or cancellation of purchase
money indebtedness for the shares within ninety (90) days of termination of
status as a Service Provider (or, in the case of shares issued upon exercise of
Options or Stock Purchase Rights, after such date of termination, within ninety
(90) days after the date of the exercise) or such longer period as may be agreed
to by the Company and the Plan participant.

    21. INVESTMENT INTENT. The Company may require a Plan participant, as a
condition of exercising or acquiring stock under any Option or Stock Purchase
Right, (i) to give written assurances satisfactory to the Company as to the
participant's knowledge and experience in financial and business matters and/or
to employ a purchaser representative reasonably satisfactory to the Company who
is knowledgeable and experienced in financial and business matters and that he
or she is capable of evaluating, alone or together with the purchaser
representative, the merits and risks of exercising the Option or Stock Purchase
Right; and (ii) to give written assurances satisfactory to the Company stating
that the participant is acquiring the stock subject to the Option or Stock
Purchase Right for the participant's own account and not with any present
intention of selling or otherwise distributing the stock. The foregoing
requirements, and any assurances given pursuant to such requirements, shall be
inoperative if (A) the issuance of the shares upon the exercise or acquisition
of stock under the applicable Option or Stock Purchase Right has been registered
under a then currently effective registration statement under the Securities Act
or (B) as to any particular requirement, a determination is made by counsel for
the Company that such requirement need not be met in the circumstances under the
then applicable securities laws. The Company may, upon advice of counsel to the
Company, place legends on stock certificates issued under the Plan as such
counsel deems necessary or appropriate in order to comply with applicable
securities laws, including, but not limited to, legends restricting the transfer
of the stock.
