1.     PURPOSES.  


        (a)    Amendment and Restatement.    The Plan amends and restates the Senomyx, Inc. 1999 Equity Incentive Plan
(the "Prior Plan") as in effect immediately prior to the effective date of this Plan. All outstanding awards granted under the Prior Plan shall remain
subject to the terms of the Prior Plan. All options granted subsequent to the effective date of this Plan shall be subject to the terms of this Plan. All share numbers in this Plan have been adjusted
to give affect to a 4-for-7 reverse stock split of the Company's Common Stock to be effected prior to IPO Date (the "Reverse
Split"). In the event that the Reverse Split is not effected, or is not effected at a 4-for-7 ratio, all share numbers in this Plan shall be adjusted
accordingly. 


        (b)    Eligible Stock Award Recipients.    The persons eligible to receive Stock Awards are Employees, Directors and
Consultants. Only Non-Employee Directors are eligible to receive Options under Section 8. 



        (c)    Available Stock Awards.    The Plan provides for the grant of the following Stock Awards: (i) Incentive
Stock Options, (ii) Nonstatutory Stock Options, (iii) Stock Purchase Awards, (iv) Stock Bonus Awards, (v) Stock Appreciation Rights, (vi) Stock Unit Awards and
(vii) Other Stock Awards. 


        (d)    General Purpose.    The Company, by means of the Plan, seeks to secure and retain the services of the group of
persons eligible to receive Stock Awards, to provide incentives for such persons to exert maximum efforts for the success of the Company and its Affiliates and to provide a means by which eligible
recipients of Stock Awards may be given an opportunity to benefit from increases in the value of the Common Stock.

fifty percent (50%) of the combined voting power of the Company's then outstanding securities other than by virtue of a merger, consolidation or similar transaction. Notwithstanding the foregoing, a
Change in Control shall not be deemed to occur (A) on account of the acquisition of securities of the Company by an investor, any affiliate thereof or any other Exchange Act Person from the
Company in a transaction or series of related transactions the primary purpose of which is to obtain financing for the Company through the issuance of equity securities or (B) solely because
the level of Ownership held by any Exchange Act Person (the "Subject Person") exceeds the designated percentage threshold of the outstanding voting
securities as a result of a repurchase or other acquisition of voting securities by the Company reducing the number of shares outstanding, provided that if a Change in Control would occur (but for the
operation of this sentence) as a result of the acquisition of voting securities by the Company, and after such share acquisition, the Subject Person becomes the Owner of any additional voting
securities that, assuming the repurchase or other acquisition had not occurred, increases the percentage of the then outstanding voting securities Owned by the Subject Person over the designated
percentage threshold, then a Change in Control shall be deemed to occur;

transaction or (B) more than fifty percent (50%) of the combined outstanding voting power of the parent of the surviving Entity in such merger, consolidation or similar transaction, in each
case in substantially the same proportions as their Ownership of the outstanding voting securities of the Company immediately prior to such transaction;

2







 




Incumbent
Board then still in office, such new member shall, for purposes of this Plan, be considered as a member of the Incumbent Board. 




        Notwithstanding
the foregoing or any other provision of this Plan, the definition of Change in Control (or any analogous term) in an individual written agreement between the Company or
any Affiliate and the Participant shall supersede the foregoing definition with respect to Stock Awards subject to such agreement (it being understood, however, that if no definition of Change in

Company or an Affiliate, whether as an Employee, Director or Consultant, is not interrupted or terminated. A change in the capacity in which the Participant renders service to the Company or an
Affiliate as an Employee, Consultant or Director or a change in the entity for which the Participant renders such service, provided that there is no interruption or termination of the Participant's
service with the Company or an Affiliate, shall not terminate a Participant's Continuous Service. For example, a change in status from an Employee of the Company to a Consultant of an Affiliate or to
a Director shall not constitute an interruption of Continuous Service. The Board or the chief executive officer of the Company, in that party's discretion, may determine whether Continuous Service
shall be considered interrupted in the case of any leave of absence approved by that party, including sick leave, military leave or any other personal leave. Notwithstanding the foregoing, a leave of
absence shall be treated as Continuous Service for purposes of vesting in a Stock Award only to such extent as may be provided in the Company's leave of absence policy or in the written terms of the
Participant's leave of absence.

4.     SHARES SUBJECT TO THE PLAN.  



        (a)    Share Reserve.    Subject to the provisions of Section 12(a) relating to Capitalization Adjustments, the
shares of Common Stock that may be issued pursuant to Stock Awards shall not exceed in the aggregate four million nine hundred sixty-five thousand (4,965,000) shares of Common Stock plus
an automatic annual increase to be added on the first day of each Company fiscal year, beginning in 2005 and ending in (and including) 2013, equal to the least of the following amounts:
(i) five percent (5%) of the Company's outstanding shares of Common Stock on the day preceding the first day of the applicable Company fiscal year (rounded to the nearest whole share),

        (b)    Reversion of Shares to the Share Reserve.    If any Stock Award shall for any reason expire or otherwise
terminate, in whole or in part, without having been exercised in full, or if any shares of Common Stock issued to a Participant pursuant to a Stock Award are forfeited to or repurchased by the
Company, including, but not limited to, any repurchase or forfeiture caused by the failure to meet a contingency or condition required for the vesting of such shares, then the shares of Common Stock
not issued under such Stock Award, or forfeited to or repurchased by the Company, shall revert to and again become available for issuance under the Plan. If any shares subject to a Stock Award are not
delivered to a Participant because such shares are withheld for the payment of taxes or the Stock Award is exercised through a reduction of shares subject to the Stock Award
(i.e., "net exercised"), the number of shares that are not delivered to the Participant shall remain available for issuance under the Plan. If the
exercise price of any Stock Award is satisfied by tendering shares of Common Stock held by the Participant (either by actual delivery or attestation), then the number of shares so tendered shall
remain available for issuance under the Plan. For purposes of qualification under Section 422 of the Code, notwithstanding anything to the contrary in this Section 4(b) and subject to
the provisions of Section 12(a) relating to Capitalization Adjustments, the aggregate maximum number of shares of Common Stock that may be issued as Incentive Stock Options shall be

shares, bought on the market or otherwise.

Sections 1(b) and 8, Stock Awards other than Incentive Stock Options may be granted to Employees, Directors and Consultants. 


        (b)    Ten Percent Stockholders.    A Ten Percent Stockholder shall not be granted an Incentive Stock Option unless
the exercise price of such Option is at least one hundred ten percent (110%) of the Fair Market
Value of the Common Stock on the date of grant and the Option is not exercisable after the expiration of five (5) years from the date of grant. 


        (c)    Section 162(m) Limitation on Annual Grants.    Subject to the provisions of Section 12(a)
relating to Capitalization Adjustments, at such time as the Company may be subject to the applicable provisions of Section 162(m) of the Code, no Employee shall be eligible to be granted
Options or Stock Appreciation Rights covering more than one million (1,000,000) shares of Common Stock during any calendar year. 


8









           (d)    Consultants.    A Consultant shall not be eligible for the grant of a Stock
Award if, at the time of grant, a
Form S-8 Registration Statement under the Securities Act ("Form S-8") is not available to register either the
offer or the sale of the Company's securities to such Consultant because of the nature of the services that the Consultant is providing to the Company, because the Consultant is not a natural person,
or because of any other rule governing the use of Form S-8. 


6.     OPTION PROVISIONS.  


        Subject to Section 8, each Option shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. All Options shall
be separately designated Incentive Stock Options or Nonstatutory Stock Options at the time of grant, and, if certificates are issued, a separate certificate or certificates shall be issued for shares
of Common Stock purchased on exercise of each type of Option. The provisions of separate Options need not be identical, but each Option shall include (through incorporation of provisions hereof by
reference in the Option or otherwise) the substance of each of the following provisions: 


        (a)    Term.    Subject to Section 8, the Board shall determine the term of an Option;  provided however that, subject to the provisions of Section 5(b) regarding Ten Percent Stockholders, no Incentive Stock Option shall be
exercisable after the expiration of ten (10) years from the date on which it was granted. 



        (b)    Exercise Price of an Incentive Stock Option.    Subject to the provisions of Section 5(b) regarding Ten
Percent Stockholders, the exercise price of each Incentive Stock Option shall be not less than one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the Option on the date
the Option is granted. Notwithstanding the foregoing, an Incentive Stock Option may be granted with an exercise price lower than that set forth in the preceding sentence if such Option is granted
pursuant to an assumption or substitution for another option in a manner satisfying the provisions of Section 424(a) of the Code. 



        (c)    Exercise Price of a Nonstatutory Stock Option.    Subject to Section 8, the Board, in its discretion,
shall determine the exercise price of each Nonstatutory Stock Option. 


        (d)    Consideration.    The purchase price of Common Stock acquired pursuant to an Option shall be paid, to the
extent permitted by applicable law, either (i) in cash at the time the Option is exercised or (ii) at the discretion of the Board at the time of the grant of the Option (or subsequently
in the case of a Nonstatutory Stock Option) (1) by delivery to the Company (either by actual delivery or attestation) of other Common Stock at the time the Option is exercised, (2) by a
"net exercise" of the Option (as further described below), (3) pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance
of Common Stock, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company from the sales proceeds
or (4) in any other form of legal consideration that may be acceptable to the Board. Unless otherwise specifically provided in the Option, the purchase price of Common Stock acquired pursuant
to an Option that is paid by delivery to the Company of other Common Stock acquired, directly or indirectly from the Company, shall be paid only by shares of the Common Stock of the Company that have
been held for more than six (6) months (or such longer or shorter period of time required to avoid a charge to earnings for financial accounting purposes). At any time that the Company is
incorporated in Delaware, payment of the Common Stock's "par value," as defined in the Delaware General Corporation Law, shall not be made by deferred payment. 


        In
the case of a "net exercise" of an Option, the Company will not require a payment of the exercise price of the Option from the Participant but will reduce the number of shares of
Common Stock issued upon the exercise by the largest number of whole shares that has a Fair Market Value that does not exceed the aggregate exercise price. With respect to any remaining balance of the
aggregate 


9







 



exercise
price, the Company shall accept a cash payment from the Participant. Shares of Common Stock will no longer be outstanding under an Option (and will therefore not thereafter be exercisable)
following the exercise of such Option to the extent of (i) shares used to pay the exercise price of an Option under the "net exercise", (ii) shares actually delivered to the Participant
as a result of such exercise and (iii) shares withheld for purposes of tax withholding. 


        (e)    Transferability of an Incentive Stock Option.    An Incentive Stock Option shall not be transferable except by
will or by the laws of descent and distribution and shall be exercisable during the lifetime of the Optionholder only by the Optionholder. Notwithstanding the foregoing, the Optionholder may, by
delivering written notice to the Company, in a form provided by or otherwise satisfactory to the Company, designate a third party who, in the event of the death of the Optionholder, shall thereafter
be entitled to exercise the Option. 


        (f)    Transferability of a Nonstatutory Stock Option.    A Nonstatutory Stock Option shall be transferable to the
extent provided in the Option Agreement. If the Nonstatutory Stock Option does not provide for transferability, then the Nonstatutory Stock Option shall not be transferable except by will or by the
laws of descent and distribution and shall be exercisable during the lifetime of the Optionholder only by the Optionholder. Notwithstanding the foregoing, the Optionholder may, by delivering written
notice to the Company, in a form provided by or otherwise satisfactory to the Company, designate a third party who, in the event of the death of the Optionholder, shall thereafter be entitled to
exercise the Option. 


        (g)    Vesting Generally.    The total number of shares of Common Stock subject to an Option may vest and therefore
become exercisable in periodic installments that may be equal. The Option may be subject to such other terms and conditions on the time or times when it may be exercised (which may be based on
performance or other criteria) as the Board may deem appropriate. The vesting provisions of individual Options may vary. The provisions of this Section 6(g) are subject to the provisions of
Section 8 and to any Option provisions governing the minimum number of shares of Common Stock as to which an Option may be exercised. 


        (h)    Termination of Continuous Service.    In the event that an Optionholder's Continuous Service terminates (for
reasons other than Cause or upon the Optionholder's death or Disability), the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to exercise such Option as
of the date of termination of Continuous Service) but only within such period of time ending on the earlier of (i) the expiration of the term of the Option as set forth in the Option Agreement
or (ii) the date three (3) months following the termination of the Optionholder's Continuous Service (or such longer or shorter period specified in the Option Agreement). If, after
termination of Continuous Service, the Optionholder does not exercise his or her Option within the time specified herein or in the Option Agreement (as applicable), the Option shall terminate. 


        (i)    Extension of Termination Date.    An Optionholder's Option Agreement may provide that if the exercise of the
Option following the termination of the Optionholder's Continuous Service (for reasons other than Cause or upon the Optionholder's death or Disability) would be prohibited at any time solely because
the issuance of shares of Common Stock 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 the Option Agreement or (ii) the expiration of a period of three (3) months after the termination of the Optionholder's Continuous Service during which the
exercise of the Option would not be in violation of such registration requirements. 


        (j)    Disability of Optionholder.    In the event that an Optionholder's Continuous Service terminates as a result of
the Optionholder's Disability, the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to exercise such Option as of the date of termination of Continuous
Service), but only within such period of time ending on the earlier of (i) the expiration of the term of the Option as set forth in the Option Agreement or (ii) the date twelve
(12) months 


10







 



following
such termination of Continuous Service (or such longer or shorter period specified in the Option Agreement). If, after termination of Continuous Service, the Optionholder does not exercise
his or her Option within the time specified herein or in the Option Agreement (as applicable), the Option shall terminate. 


        (k)    Death of Optionholder.    In the event that (i) an Optionholder's Continuous Service terminates as a
result of the Optionholder's death or (ii) the Optionholder dies within the period (if any) specified in the Option Agreement after the termination of the Optionholder's Continuous Service for
a reason
other than death, then the Option may be exercised (to the extent the Optionholder was entitled to exercise such Option as of the date of death) by the Optionholder's estate, by a person who acquired
the right to exercise the Option by bequest or inheritance or by a person designated to exercise the option upon the Optionholder's death pursuant to Section 6(e) or 6(f), but only within the
period ending on the earlier of (i) the expiration of the term of such Option as set forth in the Option Agreement or (ii) the date eighteen (18) months following the date of
death (or such longer or shorter period specified in the Option Agreement). If, after the Optionholder's death, the Option is not exercised within the time specified herein or in the Option Agreement
(as applicable), the Option shall terminate. 


        (l)    Termination for Cause.    In the event that an Optionholder's Continuous Service is terminated for Cause, the
Option shall terminate upon the termination date of such Optionholder's Continuous Service, and the Optionholder shall be prohibited from exercising his or her Option from and after the time of such
termination of Continuous Service. 


        (m)    Early Exercise.    The Option may include a provision whereby the Optionholder may elect at any time before the
Optionholder's Continuous Service terminates to exercise the Option as to any part or all of the shares of Common Stock subject to the Option prior to the full vesting of the Option. Any unvested
shares of Common Stock so purchased may be subject to a repurchase option in favor of the Company or to any other restriction the Board determines to be appropriate. The Company shall not be required
to exercise its repurchase option until at least six (6) months (or such longer or shorter period of time required to avoid a charge to earnings for financial accounting purposes) have elapsed
following exercise of the Option unless the Board otherwise specifically provides in the Option. 


7.     PROVISIONS OF STOCK AWARDS OTHER THAN OPTIONS.  


        (a)    Stock Purchase Awards.    Each Stock Purchase Award Agreement shall be in such form and shall contain such
terms and conditions as the Board shall deem appropriate. At the Board's election, shares of Common Stock may be (i) held in book entry form subject to the Company's instructions until any
restrictions relating to the Stock Purchase Award lapse; or (ii) evidenced by a certificate, which certificate shall be held in such form and manner as determined by the Board. The terms and
conditions of Stock Purchase Award Agreements may change from time to time, and the terms and conditions of separate Stock Purchase Award Agreements need not be identical,  provided, however, that each
Stock Purchase Award Agreement shall include (through incorporation of the provisions hereof by reference in the agreement
or otherwise) the substance of each of the following provisions: 



        (i)    Purchase Price.    At the time of the grant of a Stock Purchase
Award, the Board will determine the price to be paid by the Participant for each share subject to the Stock Purchase Award. To the extent required by applicable law, the price to be paid by the
Participant for each share of the Stock Purchase Award will not be less than the par value of a share of Common Stock. 


        (ii)    Consideration.    At the time of the grant of a Stock Purchase
Award, the Board will determine the consideration permissible for the payment of the purchase price of the Stock Purchase Award. The purchase price of Common Stock acquired pursuant to the Stock
Purchase Award shall be paid either: (i) in cash at the time of purchase or (ii) in any other form of legal 



11







 




consideration
that may be acceptable to the Board and permissible under the Delaware General Corporation Law. 


        (iii)    Vesting.    Shares of Common Stock acquired under a Stock
Purchase Award may be subject to a share repurchase right or option in favor of the Company in accordance with a vesting schedule to be determined by the Board. 


        (iv)    Termination of Participant's Continuous Service.    In the
event that a Participant's Continuous Service terminates, the Company shall have the right, but not the obligation, to repurchase or otherwise reacquire, any or all of the shares of Common Stock held
by the Participant that have not vested as of the date of termination under the terms of the Stock Purchase Award Agreement. At the Board's election, the repurchase right may be at the least of:
(i) the Fair Market Value on the relevant date or (ii) the Participant's original cost. The Company shall not be required to exercise its repurchase option until at least six
(6) months (or such longer or shorter period of time required to avoid a charge to earnings for financial accounting purposes) have elapsed following the purchase of the restricted stock unless
otherwise determined by the Board or provided in the Stock Purchase Award Agreement. 


        (v)    Transferability.    Rights to purchase or receive shares of
Common Stock granted under a Stock Purchase Award shall be transferable by the Participant only upon such terms and conditions as are set forth in the Stock Purchase Award Agreement, as the Board
shall determine in its discretion, and so long as Common Stock awarded under the Stock Purchase Award remains subject to the terms of the Stock Purchase Award Agreement. 




        (b)    Stock Bonus Awards.    Each Stock Bonus Award Agreement shall be in such form and shall contain such terms and
conditions as the Board shall deem appropriate. At the Board's election, shares of Common Stock may be (i) held in book entry form subject to the Company's instructions until any restrictions
relating to the Stock Bonus Award lapse; or (ii) evidenced by a certificate, which certificate shall be held in such form and manner as determined by the Board. The terms and conditions of
Stock Bonus Award Agreements may change from time to time, and the terms and conditions of separate Stock Bonus Award Agreements need not be identical, but each Stock Bonus Award Agreement shall
include (through incorporation of provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions: 



        (i)    Consideration.    A Stock Bonus Award may be awarded in
consideration for past services actually rendered to the Company or an Affiliate. 



        (ii)    Vesting.    Shares of Common Stock awarded under the Stock
Bonus Award Agreement may be subject to forfeiture to the Company in accordance with a vesting schedule to be determined by the Board. 


        (iii)    Termination of Participant's Continuous Service.    In the
event a Participant's Continuous Service terminates, the Company may receive via a forfeiture condition, any or all of the shares of Common Stock held by the Participant which have not vested as of
the date of termination of Continuous Service under the terms of the Stock Bonus Award Agreement. 



        (iv)    Transferability.    Rights to acquire shares of Common Stock
under the Stock Bonus Award Agreement shall be transferable by the Participant only upon such terms and conditions as are set forth in the Stock Bonus Award Agreement, as the Board shall determine in
its discretion, so long as Common Stock awarded under the Stock Bonus Award Agreement remains subject to the terms of the Stock Bonus Award Agreement. 




        (c)    Stock Unit Awards.    Each Stock Unit Award Agreement shall be in such form and shall contain such terms and
conditions as the Board shall deem appropriate. The terms and conditions of Stock Unit Award Agreements may change from time to time, and the terms and conditions of 


12







 

separate
Stock Unit Award Agreements need not be identical, provided, however, that each Stock Unit Award Agreement shall include (through incorporation
of the provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions: 



        (i)    Consideration.    At the time of grant of a Stock Unit Award,
the Board will determine the consideration, if any, to be paid by the Participant upon delivery of each share of Common Stock subject to the Stock Unit Award. To the extent required by applicable law,
the consideration to be paid by the Participant for each share of Common Stock subject to a Stock Unit Award will not be less than the par value of a share of Common Stock. The consideration may be
paid in any form permitted under applicable law. 


        (ii)    Vesting.    At the time of the grant of a Stock Unit Award,
the Board may impose such restrictions or conditions to the vesting of the Stock Unit Award as it, in its discretion, deems appropriate. 


        (iii)    Payment.    A Stock Unit Award may be settled by the delivery
of shares of Common Stock, their cash equivalent, any combination thereof or in any other form of consideration as determined by the Board and contained in the Stock Unit Award Agreement. 



        (iv)    Additional Restrictions.    At the time of the grant of a
Stock Unit Award, the Board, as it deems appropriate, may impose such restrictions or conditions that delay the delivery of the shares of Common Stock (or their cash equivalent) subject to a Stock
Unit Award after the vesting of such Stock Unit Award. 


        (v)    Dividend Equivalents.    Dividend equivalents may be credited
in respect of shares of Common Stock covered by a Stock Unit Award, as determined by the Board and contained in the Stock Unit Award Agreement. At the discretion of the Board, such dividend
equivalents may be converted into additional shares of Common Stock covered by the Stock Unit Award in such manner as determined by the Board. Any additional shares covered by the Stock Unit Award
credited by reason of such dividend equivalents will be subject to all the terms and conditions of the underlying Stock Unit Award Agreement to which they relate. 


        (vi)    Termination of Participant's Continuous Service.    Except as
otherwise provided in the applicable Stock Unit Award Agreement, such portion of the Stock Unit Award that has not vested will be forfeited upon the Participant's termination of Continuous Service for
any reason. 




        (d)    Stock Appreciation Rights.    Each Stock Appreciation Right Agreement shall be in such form and shall contain
such terms and conditions as the Board shall deem appropriate. The terms and conditions of Stock Appreciation Right Agreements may change from time to time, and the terms and conditions of separate
Stock Appreciation Right Agreements need not be identical, provided, however, that each Stock Appreciation Right Agreement shall include (through
incorporation of the provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions: 



        (i)    Strike Price and Calculation of Appreciation.    Each Stock
Appreciation Right will be denominated in share of Common Stock equivalents. The appreciation distribution payable on the exercise of a Stock Appreciation Right will be not greater than an amount
equal to the excess of (A) the aggregate Fair Market Value (on the date of the exercise of the Stock Appreciation Right) of a number of shares of Common Stock equal to the number of share of
Common Stock equivalents in which the Participant is vested under such Stock Appreciation Right, and with respect to which the Participant is exercising the Stock Appreciation Right on such date, over
(B) an amount (the strike price) that will be determined by the Board at the time of grant of the Stock Appreciation Right. 



13







 

        (ii)    Vesting.    At the time of the grant of a Stock Appreciation
Right, the Board may impose such restrictions or conditions to the vesting of such Stock Appreciation Right as it, in its discretion, deems appropriate. 



        (iii)    Exercise.    To exercise any outstanding Stock Appreciation
Right, the Participant must provide written notice of exercise to the Company in compliance with the provisions of the Stock Appreciation Right Agreement evidencing such Stock Appreciation Right. 


        (iv)    Payment.    The appreciation distribution in respect to a
Stock Appreciation Right may be paid in Common Stock, in cash, in any combination of the two or in any other form of consideration as determined by the Board and contained in the Stock Appreciation
Right Agreement evidencing such Stock Appreciation Right. 


        (v)    Termination of Continuous Service.    In the event that a
Participant's Continuous Service terminates, the Participant may exercise his or her Stock Appreciation Right (to the extent that the Participant was entitled to exercise such Stock Appreciation Right
as of the date of termination) but only within such period of time ending on the earlier of (i) the date three (3) months following the termination of the Participant's Continuous
Service (or such longer or shorter period specified in the Stock Appreciation Right Agreement) or (ii) the expiration of the term of the Stock Appreciation Right as set forth in the Stock
Appreciation Right Agreement. If, after termination, the Participant does not exercise his or her Stock Appreciation Right within the time specified herein or in the Stock Appreciation Right Agreement
(as applicable), the Stock Appreciation Right shall terminate. 




        (e)    Other Stock Awards.    Other forms of Stock Awards valued in whole or in part by reference to, or otherwise
based on, Common Stock may be granted either alone or in addition to Stock Awards provided for under Section 6 and the preceding provisions of this Section 7. Subject to the provisions
of the Plan, the Board shall have sole and complete authority to determine the persons to whom and the time or times at which such Other Stock Awards will be granted, the number of shares of Common
Stock (or the cash equivalent thereof) to be granted pursuant to such Other Stock Awards and all other terms and conditions of such Other Stock Awards. 


8.     NON-EMPLOYEE DIRECTORS' NONSTATUTORY STOCK OPTION PROGRAM.  


        Without any further action by the Board, automatic Option grants shall be made under the Plan in accordance with this Section 8 to Non-Employee
Directors who meet the criteria specified in Section 8(a). All Options granted under this Section 8 shall be Nonstatutory Stock Options and shall be in such form as may be approved by
the Board, subject to the provisions of the Plan and Section 8. 


        (a)    Non-Discretionary Grants.    



        (i)    IPO Date Grants.    Without any further action of the Board,
each person who is serving as a Non-Employee Director on the IPO Date (except for individuals appointed to such position by the Board in 2004) shall, upon the IPO Date, be automatically
granted an Initial Grant to purchase twenty-eight thousand six hundred (28,600) shares of Common Stock (except that the Chairman of the Board shall instead be granted an Initial Grant covering
forty-two thousand nine hundred (42,900) shares of Common Stock) on the terms and conditions set forth herein. 


        (ii)    Initial Grants.    Without any further action of the Board,
each person who after the IPO Date is elected or appointed for the first time to be a Non-Employee Director (other than the Chairman of the Board) shall, upon the date of such election or
appointment, be automatically granted an Initial Grant to purchase twenty-eight thousand six hundred (28,600) shares of Common Stock on the terms and conditions set forth herein. Each person who after
the IPO Date is elected or appointed for the first time to serve as the Chairman of the Board shall, upon the date of such election or appointment, be automatically granted an Initial Grant on the
terms and 



14







 




conditions
set forth herein to purchase forty-two thousand nine hundred (42,900) shares of Common Stock to the extent that such individual was not already serving on the Board or fourteen
thousand three hundred (14,300) shares of Common Stock to the extent that such individual was already serving on the Board. 


        (iii)    Annual Grants.    Without any further action of the Board, on
the date of each Annual Meeting, commencing with the Annual Meeting in 2005, each person who is then a Non-Employee Director and who is re-elected to serve on the Board at such
Annual Meeting, shall be automatically granted, effective immediately following such re-election, an Annual Grant to purchase eleven thousand four hundred forty (11,440) shares of Common
Stock (except that a person who is re-elected to serve as Chairman of the Board shall instead be granted an Annual Grant covering seventeen thousand one hundred sixty (17,160) shares of
Common Stock) on the terms and conditions set forth herein; provided, however, that if such person did not serve as a Non-Employee Director
for the full period since the preceding Annual Meeting, then the number of shares subject to such Annual Grant shall be reduced to the number obtained by multiplying the number that would otherwise be
subject to such Annual Grant by a fraction, the numerator of which is the number of full one-month periods between the date of such person's initial appointment or election to the Board
and the date of such Annual Meeting and the denominator of which is twelve (12). 




        (b)    Option Provisions.    Each Option granted under this Section 8 shall include (through incorporation by
reference in the Option or otherwise) the substance of each of the provisions of Section 6, except that no Option granted under this Section 8 shall be exercisable after the expiration
of ten (10) years after the date on which it was granted and the exercise price of each Option granted under this Section 8
shall be one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the Option on the date the Option is granted. 


9.     COVENANTS OF THE COMPANY.  


        (a)    Availability of Shares.    During the terms of the Stock
Awards, the Company shall keep available at all times the number of shares of Common Stock required to satisfy such Stock Awards. 


        (b)    Securities Law Compliance.    The Company shall seek to obtain from each regulatory commission or agency having
jurisdiction over the Plan such authority as may be required to grant Stock Awards and to issue and sell shares of Common Stock upon exercise of the Stock Awards; provided,
however, that this undertaking shall not require the Company to register under the Securities Act the Plan, any Stock Award or any Common Stock issued or issuable pursuant to
any such Stock Award. If, after reasonable efforts, the Company is unable to obtain from any such regulatory commission or agency the authority which counsel for the Company deems necessary for the
lawful issuance and sale of Common Stock under the Plan, the Company shall be relieved from any liability for failure to issue and sell Common Stock upon exercise of such Stock Awards unless and until
such authority is obtained. 


10.   USE OF PROCEEDS FROM STOCK.  



        Proceeds from the sale of Common Stock pursuant to Stock Awards shall constitute general funds of the Company. 


11.   MISCELLANEOUS.  


        (a)    Acceleration of Exercisability and Vesting.    The Board shall
have the power to accelerate the time at which a Stock Award may first be exercised or the time during which a Stock Award or any part thereof will vest in accordance with the Plan, notwithstanding
the provisions in the Stock Award stating the time at which it may first be exercised or the time during which it will vest. 


15







 

        (b)    Stockholder Rights.    No Participant shall be deemed to be the holder of, or to have any of the rights of a
holder with respect to, any shares of Common Stock subject to such Stock Award unless and until such Participant has satisfied all requirements for exercise of the Stock Award pursuant to its terms. 



        (c)    No Employment or other Service Rights.    Nothing in the Plan, any Stock Award Agreement or other instrument
executed thereunder or any Stock Award granted pursuant thereto shall confer upon any Participant any right to continue to serve the Company or an Affiliate in the capacity in effect at the time the
Stock Award was granted or shall affect the right of the Company or an Affiliate to terminate (i) the employment of an Employee with or without notice and with or without cause, (ii) the
service of a Consultant pursuant to the terms of such Consultant's agreement with the Company or an Affiliate or (iii) the service of a Director pursuant to the Bylaws of the Company or an
Affiliate, and any applicable provisions of the corporate law of the state in which the Company or the Affiliate is incorporated, as the case may be. 


        (d)    Incentive Stock Option $100,000 Limitation.    To the extent that the aggregate Fair Market Value (determined
at the time of grant) of Common Stock with respect to which Incentive Stock Options are exercisable for the first time by any Optionholder during any calendar year (under all plans of the Company and
its Affiliates) exceeds one hundred thousand dollars ($100,000), the Options or portions thereof that exceed such limit (according to the order in which they were granted) shall be treated as
Nonstatutory Stock Options, notwithstanding any contrary provision of the applicable Option Agreement(s). 



        (e)    Investment Assurances.    The Company may require a Participant, as a condition of exercising or acquiring
Common Stock under any Stock Award, (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 Stock Award; and (ii) to give written assurances satisfactory to the Company stating that the Participant is
acquiring Common Stock subject to the Stock Award for the Participant's own account and not with any present intention of selling or otherwise distributing the Common Stock. The foregoing
requirements, and any assurances given pursuant to such requirements, shall be inoperative if (1) the issuance of the shares of Common Stock upon the exercise or acquisition of Common Stock
under the Stock Award has been registered under a then currently effective registration statement under the Securities Act or (2) 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 Common Stock. 


        (f)    Withholding Obligations.    To the extent provided by the terms of a Stock Award Agreement, the Company may in
its discretion, satisfy any federal, state or local tax withholding obligation relating to a Stock Award by any of the following means (in addition to the Company's right to withhold from any
compensation paid to the Participant by the Company) or by a combination of such means: (i) causing the Participant to tender a cash payment; (ii) withholding shares of Common Stock from
the shares of Common Stock issued or otherwise issuable to the Participant in connection with the Stock Award; or (iii) by such other method as may be set forth in the Stock Award Agreement. 


16







 



12.   ADJUSTMENTS UPON CHANGES IN STOCK.  


        (a)    Capitalization Adjustments.    If any change is made in, or
other event occurs with respect to, the Common Stock subject to the Plan or subject to any Stock Award without the receipt of consideration by the Company (through merger, consolidation,
reorganization, recapitalization, reincorporation, stock dividend, dividend in property other than cash, stock split, liquidating dividend, combination of shares, exchange of shares, change in
corporate structure or other transaction not involving the receipt of consideration by the Company (each a "Capitalization Adjustment"), then
(i) the Plan will be appropriately adjusted in the class(es) and maximum number of securities subject to the Plan pursuant to Sections 4(a) and 4(b), the maximum number of securities
subject to award to any person pursuant to Section 5(c) and the number of securities subject to the automatic Option grants under Section 8 and (ii) the outstanding Stock Awards
will be appropriately adjusted in the class(es) and number of securities and price per share of Common Stock subject to such outstanding Stock Awards. The Board shall make such adjustments, and its
determination shall be final, binding and conclusive. (Notwithstanding the foregoing, the conversion of any convertible securities of the Company shall not be treated as a transaction "without receipt
of consideration" by the Company.) 


        (b)    Dissolution or Liquidation.    In the event of a dissolution or liquidation of the Company, all outstanding
Stock Awards (other than Stock Awards consisting of vested Common Stock not subject to the Company's right of repurchase) shall terminate immediately prior to the completion of such dissolution or
liquidation, and Common Stock subject to the Company's repurchase option may be repurchased by the Company notwithstanding the fact that the holder of such stock is still in Continuous Service;  provided however that,
 the Board may, in its discretion, cause some or all Stock Awards to be fully vested, exercisable and/or no longer subject to
repurchase (to the extent such Stock
Awards have not previously expired or terminated) before the dissolution or liquidation is completed but contingent on its completion. 


        (c)    Corporate Transaction.    In the event of a Corporate Transaction, any surviving corporation or acquiring
corporation may assume or continue any or all Stock Awards outstanding under the Plan or may substitute similar stock awards for Stock Awards outstanding under the Plan (including but not limited to,
awards to acquire the same consideration paid to the stockholders of the Company, as the case may be, pursuant to the Corporate Transaction), and any reacquisition or repurchase rights held by the
Company in respect of Common Stock issued pursuant to Stock Awards may be assigned by the Company to the successor of the Company (or the successor's parent company), if any, in connection with such
Corporate Transaction. In the event that any surviving corporation or acquiring corporation does not assume or continue all such outstanding Stock Awards or substitute similar stock awards for all
such outstanding Stock Awards, then with respect to Stock Awards that have been not assumed, continued or substituted and that are held by Participants whose Continuous Service has not terminated
prior to the effective time of the Corporate Transaction, the vesting of such Stock Awards (and, if applicable, the time at which such Stock Awards may be exercised) shall (contingent upon the
effectiveness of the Corporate Transaction) be accelerated in full to a date prior to the effective time of such Corporate Transaction as the Board shall determine (or, if the Board shall not
determine such a date, to the date that is five (5) days prior to the effective time of the Corporate Transaction), and such Stock Awards shall terminate if not exercised (if applicable) at or
prior to such effective time and any reacquisition or repurchase rights held by the Company with respect to such Stock Awards shall (contingent upon the effectiveness of the Corporate Transaction)
lapse. With respect to any other Stock Awards outstanding under the Plan that have not been assumed, continued or substituted, the vesting of such Stock Awards (and, if applicable, the time at which
such Stock Award may be exercised) shall not be accelerated, unless otherwise provided in a written agreement between the Company or any Affiliate and the holder of such Stock Award, and such Stock
Awards shall terminate if not exercised (if applicable) prior to the effective time of the Corporate Transaction.

        (d)    Change in Control.    A Stock Award may be subject to additional acceleration of vesting and exercisability
upon or after a Change in Control as may be provided in the Stock Award Agreement for such Stock Award or as may be provided in any other written agreement between the Company or any Affiliate and the
Participant, but in the absence of such provision, no such acceleration shall occur. 


13.   AMENDMENT OF THE PLAN AND STOCK AWARDS.  


        (a)    Amendment of Plan.    Subject to the limitations, if any, of
applicable law, the Board at any time, and from time to time, may amend the Plan. However, except as provided in Section 12(a) relating to
Capitalization Adjustments, no amendment shall be effective unless approved by the stockholders of the Company to the extent stockholder approval is necessary to satisfy applicable law. 


        (b)    Stockholder Approval.    The Board, in its discretion, may submit any other amendment to the Plan for
stockholder approval, including, but not limited to, amendments to the Plan intended to satisfy the requirements of Section 162(m) of the Code and the regulations thereunder regarding the
exclusion of performance-based compensation from the limit on corporate deductibility of compensation paid to Covered Employees. 



        (c)    Contemplated Amendments.    It is expressly contemplated that the Board may amend the Plan in any respect the
Board deems necessary or advisable to provide eligible Employees with the maximum benefits provided or to be provided under the provisions of the Code and the regulations promulgated thereunder
relating to Incentive Stock Options and/or to bring the Plan and/or Incentive Stock Options granted under it into compliance therewith. 


        (d)    No Impairment of Rights.    Rights under any Stock Award granted before amendment of the Plan shall not be
impaired by any amendment of the Plan unless (i) the Company requests the consent of the Participant and (ii) the Participant consents in writing. 


        (e)    Amendment of Stock Awards.    The Board at any time, and from time to time, may amend the terms of any one or
more Stock Awards, including, but not limited to, amendments to provide terms more favorable than previously provided in the agreement evidencing a Stock Award, subject to any specified limits in the
Plan that are not subject to Board discretion; provided, however, that the rights under any Stock Award shall not be impaired by any such amendment
unless (i) the Company requests the consent of the Participant and (ii) the Participant consents in writing. 


14.   TERMINATION OR SUSPENSION OF THE PLAN.  


        (a)    Plan Term.    The Board may suspend or terminate the Plan at
any time. Unless sooner terminated, the Plan shall terminate on the day before the tenth (10th) anniversary of the date the Plan is adopted by the Board or approved by the stockholders of the Company,
whichever is earlier. No Stock Awards may be granted under the Plan while the Plan is suspended or after it is terminated. 



        (b)    No Impairment of Rights.    Suspension or termination of the Plan shall not impair rights and obligations under
any Stock Award granted while the Plan is in effect except with the written consent of the Participant. 


15.   EFFECTIVE DATE OF PLAN.  


        The Plan shall become effective on the IPO Date, but no Stock Award shall be exercised (or, in the case of a stock bonus, shall be granted) unless and until the
Plan has been approved by the stockholders of the Company, which approval shall be within twelve (12) months before or after the date the Plan is adopted by the Board.

16.   CHOICE OF LAW.  


        The law of the State of California shall govern all questions concerning the construction, validity and interpretation of this Plan, without regard to such
state's conflict of laws rules.
