SECTION 2. ADMINISTRATION.

     The Plan shall be administered in accordance with the requirements of
Section 162(m) of the Code (but only to the extent necessary and desirable to
maintain qualification of awards under the Plan under Section 162(m) of the
Code) and, to the extent applicable, Rule 16b-3, by the Board or, at the Board's
sole discretion, by the Committee, which shall be appointed by the Board, and
which shall serve at the pleasure of the Board.

     Pursuant to the terms of the Plan, the Administrator shall have the power
and authority to grant Stock Options to Eligible Recipients pursuant to the
terms of the Plan. The Administrator may delegate to officers of the Company the
authority to grant Stock Options under this Plan to Eligible Recipients who are
not officers or directors of the Company whose transactions in the Company's
Common Stock are subject to Section 16(b) of the Exchange Act.

     Additionally, subject to the terms and provisions of the Plan, the
Administrator's powers shall include, without limitation, the authority to:

          (1) select those Eligible Recipients who shall be Optionees;

          (2) determine whether and to what extent Stock Options are to be
     granted hereunder to Optionees including whether a Stock Option is to be an
     Incentive Stock Option or a Non-Qualified Stock Option;

          (3) determine the number of Shares to be covered by each such Stock
     Option granted hereunder, the exercise price of a Stock Option and the
     period during which the Stock Option may be exercised;

          (4) determine other terms and conditions, not inconsistent with the
     terms of the Plan, of each Stock Option granted hereunder;

          (5) determine whether an Optionee has ceased to be employed or
     retained by the Company or any Parent, Subsidiary or Affiliate of the
     Company and the effective date on which such employment terminated and
     whether an Optionee who is a director, consultant, independent contractor
     or advisor is employed or retained by the Company or any Parent, Subsidiary
     or Affiliate of the Company;

          (6) adopt, alter and repeal such administrative rules, guidelines and
     practices governing the Plan as it shall from time to time deem advisable;
<PAGE>

          (7) interpret the terms and provisions of the Plan and any award
     issued under the Plan (and any agreements relating thereto); and

          (8) otherwise supervise the administration of the Plan.

     All decisions and interpretations made by the Administrator pursuant to the
provisions of the Plan shall be final, conclusive and binding on the Company and
all persons having an interest in any Stock Option or any Shares purchased
pursuant to a Stock Option.

SECTION 3. STOCK SUBJECT TO PLAN.

     The total number of Shares reserved and available for issuance under the
Plan shall be 2,500,000. Such Shares may consist, in whole or in part, of
authorized and unissued shares or treasury shares. No one Optionee shall be
eligible to receive more than 500,000 Shares during any single calendar year
during the term of this Plan pursuant to the grant of Stock Options hereunder.
Upon shareholder approval of the Plan, (1) the Company's 1995 Stock Option Plan
(the "1995 Plan") shall be merged and incorporated into the Plan, effective
immediately prior to the 2001 annual meeting of the shareholders of the Company,
(2) all outstanding options under the 1995 Plan shall be treated as outstanding
under the Plan; provided however, that each outstanding option so incorporated
shall be governed solely by the express terms and conditions of the 1995 Plan
and all other instruments evidencing the grant of such options, and (3) all
available shares for grant under the 1995 Plan as of such date shall be
available for grant hereunder, and any and all shares that would otherwise be
returned to the 1995 Plan by reason of expiration of its term or cancellation
upon termination of employment or service shall be available again for grant
hereunder as of such date of cancellation or termination. Effective immediately
prior to the 2001 annual meeting of the shareholders of the Company, and subject
to shareholder approval of the Plan at such meeting, the 1995 Plan shall
terminate and no further option grants shall be made therefrom.

     Consistent with the provisions of Section 162(m) of the Code, as from time
to time applicable, to the extent that a Stock Option expires or is otherwise
terminated without being exercised, such Shares shall again be available for
issuance in connection with future awards granted under the Plan. If any Shares
have been pledged as collateral for indebtedness incurred by an Optionee in
connection with the exercise of a Stock Option and such Shares are returned to
the Company in satisfaction of such indebtedness, such Shares shall again be
available for issuance in connection with future awards granted under the Plan.

     In the event of any merger, reorganization, consolidation,
recapitalization, stock dividend, stock split, combination or other change in
the capital structure of the Company, as may be determined by the Administrator,
in its sole discretion and subject to any required action by the Board or
shareholders of the Company and compliance with applicable securities laws, a
substitution or adjustment shall be made in (i) the aggregate number of Shares
reserved for issuance under the Plan and (ii) the kind, number and option price
of Shares subject to outstanding Stock Options granted under the Plan; provided,
however, that the number of shares subject to any award shall always be a whole
number; and provided further, that the exercise price may not be decreased to
below the par value, if any, for the Shares. Such other substitutions or
adjustments shall be made as may be determined by the Administrator, in its sole
discretion. In connection with any event described in this paragraph, the
Administrator may provide, in its sole discretion, for the cancellation of any
outstanding awards and payment in cash or other property therefor.

SECTION 4. ELIGIBILITY.

     Non-Qualified Stock Options may be granted to employees, directors,
consultants, officers, independent contractors and advisors (provided such
consultants, independent contractors and advisors render bona fide services not
in connection with the offer or sale of securities in a capital-raising
transaction) of the Company or any Parent, Subsidiary or Affiliate of the
Company. Incentive Stock Options may be granted only to employees (including
officers and directors who are also employees) of the Company or a Parent or
Subsidiary of the Company.
<PAGE>

SECTION 5. STOCK OPTIONS.

     The Stock Options granted under the Plan may be of two types: (i) Incentive
Stock Options and (ii) Non-Qualified Stock Options. The Administrator shall have
the authority to grant to any Eligible Recipient Incentive Stock Options,
Non-Qualified Stock Options, or both types of Stock Options. To the extent that
any Stock Option does not qualify as an Incentive Stock Option, it shall
constitute a separate Non-Qualified Stock Option. More than one Stock Option may
be granted to the same Optionee and be outstanding concurrently hereunder.

     Any Stock Option granted under the Plan shall be in such form as the
Administrator may from time to time approve, and the provisions of Stock Option
awards need not be the same with respect to each Optionee. Stock Options granted
under the Plan shall be subject to the following terms and conditions and shall
contain such additional terms and conditions, not inconsistent with the terms of
the Plan, as the Administrator shall deem desirable:

          (1) Form of Stock Option Grant. Optionees who are granted Stock
     Options shall enter into a stock option agreement with the Company, in such
     form (which need not be the same for each Optionee) as the Administrator
     shall from time to time approve, which stock option agreement shall comply
     with and be subject to the terms and conditions of this Plan.

          (2) Date of Grant. The date of grant of a Stock Option shall be the
     date on which the Administrator makes the determination to grant such Stock
     Option unless otherwise specified by the Administrator. The stock option
     agreement representing the Stock Option will be delivered to the Optionee
     with a copy of this Plan within a reasonable time after the granting of the
     Stock Option.

          (3) Exercise Price. The option price per Share purchasable under a
     Stock Option shall be determined by the Administrator, in its sole
     discretion, on the date the Stock Option is granted; provided that (i) the
     exercise price of a Non-Qualified Stock Option shall not be less than 85%
     of the Fair Market Value of the Shares on the date the Stock Option is
     granted; (ii) the exercise price of an Incentive Stock Option shall be not
     less than 100% of the Fair Market Value of the Shares on the date the Stock
     Option is granted; and (iii) if an Incentive Stock Option is granted to a
     Ten Percent Shareholder, the exercise price of such Incentive Stock Option,
     to the extent required at the time of grant by the Code, shall be no less
     than 110% of the Fair Market Value of the Common Stock on the date such
     Incentive Stock Option is granted.

          (4) Exercise Period. Subject to this Section 5 and Section 10 herein,
     Stock Options shall be exercisable within the times or upon the events
     determined by the Administrator as set forth in the respective stock option
     agreement; provided, however, that no Stock Option shall be exercisable
     after the expiration of ten (10) years from the date the Stock Option is
     granted and provided, further, that no Incentive Stock Option granted to a
     Ten Percent Shareholder shall be exercisable after the expiration of five
     (5) years from the date the Stock Option is granted.

          (5) Limitations on Incentive Stock Options. The aggregate Fair Market
     Value (determined as of the time the Incentive Stock Option is granted) of
     Shares with respect to which Incentive Stock Options are exercisable for
     the first time by an Optionee during any calendar year (under this Plan or
     under any other incentive stock option plan of the Company or of any Parent
     or Subsidiary) shall not exceed $100,000. If the Fair Market Value of
     Shares with respect to which Incentive Stock Options are exercisable for
     the first time by an Optionee during any calendar year exceeds $100,000,
     the Stock Options for the first $100,000 worth of Shares to become
     exercisable in such year shall be Incentive Stock Options and the Stock
     Options for the amount in excess of $100,000 that become exercisable in
     that year shall be Non-Qualified Stock Options. In the event that the Code
     or the regulations promulgated thereunder are amended after the effective
     date of this Plan to provide for a different limit on the Fair Market Value
     of Shares permitted to be subject to Incentive Stock Options, such
     different limit shall be incorporated herein and shall apply to any Stock
     Options granted after the effective date of such amendment.
<PAGE>

          (6) Stock Options Non-Transferable. Stock Options granted under this
     Plan, and any interest therein, shall not be transferable or assignable by
     an Optionee, and may not be made subject to execution, attachment or
     similar process, otherwise than by will or by the laws of descent and
     distribution, and shall be exercisable during the lifetime of the Optionee
     only by such Optionee; provided, however, that Non-Qualified Stock Options
     may be transferred to such family members, trusts and charitable
     institutions as the Administrator, in its sole discretion, shall approve at
     the time of the grant of such Stock Option.

          (7) Assumed Stock Options. In the event the Company assumes a stock
     option granted by another company unless otherwise determined by the
     Administrator, the terms and conditions of such option shall remain
     unchanged (except the exercise price and the number and nature of shares
     issuable upon exercise, which will be adjusted appropriately pursuant to
     Section 424(a) of the Code). In the event the Company elects to grant a new
     stock option rather than assuming an existing option, such new option may
     be granted with a similarly adjusted exercise price.

          (8) Exercise of Stock Options.

             (a) Notice. Stock Options may be exercised only by delivery
        (including electronic delivery or other delivery method approved by the
        Administrator) to the Company of a written stock option exercise
        agreement in a form approved by the Administrator (which need not be the
        same for each Optionee), stating the number of Shares being purchased,
        the restrictions imposed on the Shares, if any, and such representations
        and agreements regarding the Optionee's investment intent and access to
        information, if any, as may be required by the Company to comply with
        applicable securities laws, together with payment in full of the
        exercise price for the number of Shares being purchased.

             (b) Payment. Payment for the Shares may be made in cash (by check)
        or, where approved by the Administrator in its sole discretion at the
        time of grant and where permitted by law: (i) by cancellation of
        indebtedness of the Company to the Optionee; (ii) by surrender of Shares
        having a Fair Market Value equal to the applicable exercise price of the
        Stock Options that have been owned by the Optionee for more than six (6)
        months (and which have been paid for within the meaning of SEC Rule 144
        and, if such Shares were purchased from the Company by use of a
        promissory note, such note has been fully paid with respect to such
        shares), or were obtained by the Optionee in the open public market;
        (iii) by tender of a full recourse promissory note having such terms as
        may be approved by the Administrator and bearing interest at the market
        rate on the date such promissory note is executed; provided, however,
        that such rate is sufficient to avoid imputation of income under
        Sections 483 and 1274 of the Code; (iv) by waiver of compensation due or
        accrued to the Optionee for services rendered; (v) provided that a
        public market for the Company's stock exists, through a "same day sale"
        commitment from the Optionee and a broker-dealer that is a member of the
        National Association of Securities Dealers (an "NASD Dealer") whereby
        the Optionee irrevocably elects to exercise the Stock Option and to sell
        a portion of the Shares so purchased to pay for the exercise price and
        whereby the NASD Dealer irrevocably commits upon receipt of such Shares
        to forward the exercise price directly to the Company; (vi) provided
        that a public market for the Company's stock exists, through a "margin"
        commitment from the Optionee and an NASD Dealer whereby the Optionee
        irrevocably elects to exercise the Stock Option and to pledge the Shares
        so purchased to the NASD Dealer in a margin account as security for a
        loan from the NASD Dealer in the amount of the exercise price, and
        whereby the NASD Dealer irrevocably commits upon receipt of such Shares
        to forward the exercise price directly to the Company; (vii) by any
        combination of the foregoing; or (viii) by any other method approved by
        the Administrator. Optionees who are not employees of the Company shall
        not be entitled to purchase Shares with a promissory note unless the
        note is adequately secured by collateral other than the Shares.

             (c) Loans. The Company may make loans available to Optionees in
        connection with the exercise of outstanding Stock Options, as the
        Administrator, in its sole discretion, may determine. Such loans shall
        (i) be evidenced by a full recourse promissory note entered into by the
        Optionee in favor of the Company, (ii) be subject to the terms and
        conditions set forth in this Section 5 and such other terms and
        conditions, not inconsistent with the Plan, as the Administrator shall
        determine,
<PAGE>

        (iii) bear interest at such rate as the Administrator shall determine
        but in no event less than the market rate on the date such promissory
        note is executed; provided, however, that such rate is sufficient to
        avoid imputation of income under Sections 483 and 1274 of the Code and
        (iv) be subject to Board approval (or to approval by the Administrator
        to the extent the Board may delegate such authority). In no event may
        the principal amount of any such loan exceed the sum of (x) the exercise
        price less the par value of the Shares covered by the Stock Option, or
        portion thereof, exercised by the Optionee, and (y) any Federal, state,
        and local income tax attributable to such exercise. The initial term of
        the loan, the schedule of payments of principal and interest under the
        loan and the conditions upon which the loan will become payable in the
        event of the holder's termination of employment or service to the
        Company or to any Subsidiary shall be determined by the Administrator,
        provided, however, that the term of the loan, including extensions,
        shall not exceed seven years. Unless the Administrator determines
        otherwise, when a loan is made, Shares having a Fair Market Value at
        least equal to the principal amount of the loan shall be pledged by the
        Optionee to the Company as security for payment of the unpaid balance of
        the loan, and such pledge shall be evidenced by a pledge agreement, the
        terms of which shall be determined by the Administrator, in its sole
        discretion; provided, however, that each loan shall comply with all
        applicable laws, regulations and rules of the Board of Governors of the
        Federal Reserve System and any other governmental agency having
        jurisdiction.

             (d) Withholding Taxes. Prior to issuance of the Shares upon
        exercise of a Stock Option, the Optionee shall pay to the Company, or
        make arrangements satisfactory to the Administrator regarding payment
        of, any Federal, state, or local taxes of any kind required by law to be
        withheld with respect to such Stock Option. The obligations of the
        Company under the Plan shall be conditional on the making of such
        payments or arrangements, and the Company shall, to the extent permitted
        by law, have the right to deduct any such taxes from any payment of any
        kind otherwise due to the Optionee.

             (e) Limitations on Exercise. The exercisability of a Stock Option
        shall be subject to the following:

                (i) The Administrator may specify a reasonable minimum number of
           Shares that may be purchased on any exercise of a Stock Option,
           provided that such minimum number will not prevent an Optionee from
           exercising the full number of Shares as to which the Stock Option is
           then exercisable.

                (ii) A Stock Option shall not be exercisable unless such
           exercise is in compliance with the Securities Act, all applicable
           state securities laws and the requirements of any stock exchange or
           national market system upon which the Shares may then be listed, as
           they are in effect on the date of exercise. The Company shall be
           under no obligation to register the Shares with the SEC or to effect
           compliance with the registration, qualification or listing
           requirements of any state securities laws, stock exchange or national
           market system, and the Company shall have no liability for any
           inability or failure to do so.

          (9) Termination of Employment or Service Other Than Due to Death or
     Disability. Unless otherwise provided in the applicable stock option
     agreement, if an Optionee ceases to be employed or retained by the Company
     or any Parent, Subsidiary or Affiliate of the Company for any reason except
     death or Disability, the Optionee may exercise such Optionee's Incentive
     Stock Options or Non-Qualified Stock Options, to the extent that they are
     exercisable on the date of termination, within three (3) months after the
     date of termination or such other time period as may be specified in the
     applicable stock option agreement (but in no event later than the
     expiration date of the term of such Stock Option as set forth in Section
     5(4) above). To the extent an Optionee was not entitled to exercise a Stock
     Option at the date of termination, or if an Optionee does not exercise such
     Stock Option to the extent so entitled within the time specified herein,
     the Stock Option shall terminate unless as otherwise provided in the
     applicable stock option agreement.
<PAGE>

          (10) Termination of Employment or Service Due to Death or
     Disability. Unless otherwise provided in the applicable stock option
     agreement, if an Optionee's employment or retention with the Company or any
     Parent, Subsidiary or Affiliate of the Company is terminated because of the
     Optionee's death or Disability, the Optionee may exercise such Optionee's
     Incentive Stock Options or Non-Qualified Stock Options, to the extent that
     they are exercisable on the date of termination, by the Optionee (or the
     Optionee's legal representative) within twelve (12) months after the date
     of termination or such other time period as may be specified in the
     applicable stock option agreement (but in no event later than the
     expiration date of the term of such Stock Option as set forth in Section
     5(4) above). To the extent an Optionee was not entitled to exercise a Stock
     Option at the date of termination, or if an Optionee does not exercise such
     Stock Option to the extent so entitled within the time specified herein,
     the Stock Option shall terminate unless as otherwise provided in the
     applicable stock option agreement.

SECTION 6. OPTION GRANTS FOR NON-EMPLOYEE DIRECTORS.

     (1) Eligibility Generally. Non-employee directors of the Company or any
Parent, Subsidiary or Affiliate of the Company shall be granted automatic Stock

each such director will be granted an additional Stock Option to purchase 15,000
Shares.

     (3) Terms and Conditions of Automatic Stock Options. The terms and
conditions of the automatic Stock Option grants to non-employee directors of the
Company or any Parent, Subsidiary or Affiliate of the Company pursuant to

     agreement representing the Stock Option will be delivered to the Optionee
     within a reasonable time after the granting of the Stock Option.

          (b) Exercise Price. The exercise price of the automatic Stock Option
     shall be the Fair Market Value of the Shares at the time that the Stock

          (c) Vesting and Exercise Period. The automatic Stock Options shall be
     fully vested and exercisable in their entirety immediately upon grant for
     the term set forth in the applicable stock option agreement; provided,

     ten (10) years from the date the Stock Option is granted.

          (d) Limitation on Exercise. If the Optionee ceases to be a director
     for any reason except death, the Optionee may exercise his or her Stock
     Options, to the extent (and only to the extent) that they are exercisable
     on the date of termination until the expiration dates of the Stock Options,
     which shall be ten (10) years from the dates the Stock Options are granted.

     legal representative may exercise his or her Stock Options to the extent
     (and only to the extent) that they are exercisable on the date of
     termination, within twelve (12) months after the date of termination, but
     not after the expiration of ten (10) years from the date the Stock Options

     representative was not entitled to exercise a Stock Option at the date of
     termination, or if an Optionee or an Optionee's legal representative does
     not exercise such Stock Option to the extent so entitled within the time
     specified herein, the Stock Option shall terminate unless as otherwise
     provided in the applicable stock option agreement.
<PAGE>

SECTION 7. MODIFICATION, EXTENSION AND RENEWAL OF STOCK OPTIONS.

     The Administrator shall have the power to modify, extend or renew
outstanding Stock Options and to authorize the grant of new Stock Options in
substitution therefor, provided that any such action may not, without the
written consent of an Optionee, impair any rights under any Stock Option
previously granted except as provided in Section 3 hereof. Any outstanding
Incentive Stock Option that is modified, extended, renewed or otherwise altered
shall be treated in accordance with Section 424(h) of the Code. The
Administrator shall not have the power to reduce the exercise price of
outstanding Stock Options.

SECTION 8. PRIVILEGES OF STOCK OWNERSHIP.

     No Optionee shall have any of the rights of a shareholder with respect to
any Shares subject to a Stock Option until such Stock Option is properly
exercised. No adjustment shall be made for dividends or distributions or other
rights for which the record date is prior to such date, except as provided in
this Plan. Upon written request, the Company shall provide to each Optionee a
copy of the annual financial statements of the Company at such time after the
close of each fiscal year of the Company as such statements are released by the
Company to its common shareholders generally.

SECTION 9. NO OBLIGATION TO EMPLOY.

     Nothing in this Plan nor any Stock Option granted under this Plan shall
confer on any Optionee any right to continue in the employ of, as a director of,
or other relationship with, the Company or any Parent, Subsidiary or Affiliate
of the Company or limit in any way the right of the Company or any Parent,
Subsidiary or Affiliate of the Company to terminate Optionee's employment or
other relationship at any time, with or without cause.

SECTION 10. CHANGE IN CONTROL; ASSUMPTION OF STOCK OPTIONS BY SUCCESSORS.

     In the event of a Change in Control, any or all outstanding Stock Options
shall, unless otherwise provided in an applicable stock option agreement or
other agreement, accelerate and become exercisable in full upon the occurrence
of the Change in Control and shall expire immediately following the occurrence
of the Change in Control. To the extent required by applicable law, the
aggregate Fair Market Value of Incentive Stock Options which first become
exercisable in the year of such Change in Control cannot exceed $100,000, and
any remaining accelerated options shall be treated as Non-Qualified Stock
Options.

SECTION 11. ADOPTION AND SHAREHOLDER APPROVAL.

     This Plan shall become effective on April 23, 2001, the date the Plan was
adopted by the Board (the "Effective Date"). This Plan shall be approved by the
shareholders of the Company, in any manner permitted by applicable corporate
law, within twelve months before or after the date this Plan was adopted by the
Board. Upon the Effective Date, the Board may grant Stock Options pursuant to
this Plan; provided that, in the event that shareholder approval is not obtained
within the time period provided herein, all Stock Options granted hereunder
shall terminate. No Stock Option that is issued as a result of any increase in
the number of shares authorized to be issued under this Plan shall be exercised
prior to the time such increase has been approved by the shareholders of the
Company and all such Stock Options granted pursuant to such increase shall
similarly terminate if such shareholder approval is not obtained.

SECTION 12. TERM OF PLAN.

     Stock Options may be granted pursuant to this Plan from time to time within
a period of ten (10) years from the Effective Date.

SECTION 13. AMENDMENT OR TERMINATION OF PLAN.

     Subject to Section 7 above, the Administrator may at any time terminate or
amend this Plan in any respect, including but not limited to, amendment of any
form of grant, exercise agreement or instrument to be
<PAGE>

executed pursuant to this Plan; provided, however, that the Administrator shall
not, without the approval of the shareholders of the Company, amend this Plan in
any manner that requires such shareholder approval pursuant to the Code or the
regulations promulgated thereunder or pursuant to the Exchange Act or Rule 16b-3
(or its successor) promulgated thereunder, to the extent the Administrator
intends the Plan to comply with such foregoing requirement or law.

SECTION 14. UNFUNDED STATUS OF PLAN.

     The Plan is intended to constitute an "unfunded" plan for incentive
compensation. With respect to any payments not yet made to an Optionee by the
Company, nothing contained herein shall give any Optionee or persons any rights
that are greater than those of a general creditor of the Company.<PAGE>
                                                                   EXHIBIT 10.08

                          GENELABS TECHNOLOGIES, INC.

                       2001 EMPLOYEE STOCK PURCHASE PLAN
              ADOPTED BY THE BOARD OF DIRECTORS ON APRIL 23, 2001

 1. ESTABLISHMENT OF PLAN

     The purpose of the Genelabs Technologies, Inc. 2001 Employee Stock Purchase
Plan (the "Plan") is to grant options for purchase of common stock, no par value
(the "Common Stock") of Genelabs Technologies, Inc. (the "Company") to eligible
employees of the Company and its Subsidiaries (as hereinafter defined). For
purposes of this Plan, "Parent Corporation" and "Subsidiary" (collectively,
"Subsidiaries") shall have the same meanings as "parent corporation" and
"subsidiary corporation" in Sections 424(e) and 424(f), respectively, of the
Internal Revenue Code of 1986, as amended (the "Code"). The Company intends the
Plan to qualify as an "employee stock purchase plan" under Section 423 of the
Code (including any amendments to or replacements of such Section), and the Plan
shall be so construed. Any term not expressly defined in the Plan but defined
for purposes of Section 423 of the Code shall have the same definition herein. A
total of 2,000,000 shares of the Company's Common Stock are reserved for
issuance under the Plan subject to certain adjustments as provided under Section
14 of the Plan.

 2. PURPOSE

     The purpose of the Plan is to provide employees of the Company and
Subsidiaries designated by the Board of Directors of the Company (the "Board")
as eligible to participate in the Plan with a convenient means of acquiring an
equity interest in the Company through payroll deductions, to enhance such
employees' sense of participation in the affairs of the Company and
Subsidiaries, and to provide an incentive for continued employment.

 3. ADMINISTRATION

     This Plan shall be administered by the Administrator. For purposes of this
plan, the "Administrator" shall mean the Board, or if and to the extent the
Board does not administer the Plan, a committee appointed by the Board (the
"Committee"). If the Committee is not comprised of "disinterested persons"
("Disinterested Persons") as defined in Rule 16b-3(d) promulgated under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), at the time
the Company is registered under the Exchange Act, unless otherwise determined by
the Administrator, the Administrator shall appoint a Committee consisting of not
less than three (3) persons (who need not be members of the Board), each of whom
is a Disinterested Person. After registration of the Company under the Exchange
Act, unless otherwise determined by the Administrator or the Board, Committee
members who are not Disinterested Persons may not vote on any matters affecting
the administration of this Plan, but any such member may be counted for
determining the existence of a quorum at any meeting of the Committee. Subject
to the provisions of the Plan and the limitations of Section 423 of the Code or
any successor provision in the Code, all questions of interpretation or
application of the Plan shall be determined by the Administrator and its
decisions shall be final and binding upon all participants. Members of the Board
shall receive no compensation for their services in connection with the
administration of the Plan, other than standard fees as established from time to
time by the Board for services rendered by Board members serving on Board
committees. All expenses incurred in connection with the administration of the
Plan shall be paid by the Company.

 4. ELIGIBILITY

     Any employee of the Company or the Subsidiaries is eligible to participate
in the Plan except the following:

          (a) employees who are not employed by the Company or Subsidiaries on
     the day before the Offering Date (as hereinafter defined);
<PAGE>

          (b) employees who are customarily employed for less than twenty (20)
     hours per week;

          (c) employees who are customarily employed for less than five (5)
     months in a calendar year; or

          (d) employees who, together with any other person whose stock would be
     attributed to such employee pursuant to Section 424(d) of the Code, own
     stock or hold options to purchase stock or who, as a result of being
     granted an option under the Plan with respect to such Offering Period,
     would own stock or hold options to purchase stock possessing five percent
     (5%) or more of the total combined voting power or value of all classes of
     stock of the Company or any of its Subsidiaries.

 5. OFFERING DATES

     The offering periods of the Plan (each, an "Offering Period") shall be of
twenty-four (24) months duration commencing on January 1 and July 1 of each year
and ending on June 30 and December 31 of each year. Each Offering Period shall
consist of four (4) six-month purchase periods (individually, a "Purchase
Period") during which payroll deductions of the participants are accumulated
under the Plan. The first business day of each Offering Period is referred to as
the "Offering Date." The last business day of each Offering Period is referred
to as the "Purchase Date." Notwithstanding the foregoing, if the fair market
value of the Company's Common Stock on any Purchase Date is equal to or is less
than such fair market value on an Offering Date, then the Offering Period(s) for
such Offering Date(s) shall immediately terminate and a new Offering Period
shall commence for those employees participating in such terminated Offering
Period(s) (See also Section 11(c) hereof). The Administrator shall have the
power to change the duration of Offering Periods or Purchase Periods with
respect to offerings without shareholder approval if such change is announced at
least fifteen (15) days prior to the scheduled beginning of the first Offering
Period or Purchase Period to be affected.

 6. PARTICIPATION IN THE PLAN

     Eligible employees may become participants in an Offering Period under the
Plan upon the commencement of the next Purchase Period after satisfying the
eligibility requirements by delivering a subscription agreement to the Company's
or Subsidiary's (whichever employs such employee) Treasury Department (the
"Treasury Department") not later than the business day before such Offering
Period begins unless an earlier time for filing the subscription agreement
authorizing payroll deductions is set by the Administrator for all eligible
employees with respect to a given Offering Period. An eligible employee who does
not deliver a subscription agreement to the Treasury Department by such date
after becoming eligible to participate in such Offering Period shall not
participate in that Offering Period or any subsequent Offering Period unless
such employee enrolls in the Plan by filing a subscription agreement with the
Treasury Department not later than the business day preceding the beginning of a
subsequent Offering Period. Once an employee becomes a participant in an
Offering Period, such employee will automatically participate in the next
Offering Period unless the employee withdraws from the Plan or terminates
further participation in a Purchase Period as set forth in Section 11 hereof.
Such participant is not required to file any additional subscription agreement
in order to continue participation in the Plan.

 7. GRANT OF OPTION ON ENROLLMENT

     Enrollment by an eligible employee in the Plan with respect to an Offering
Period will constitute the grant (as of the Offering Date) by the Company to
such employee of an option to purchase on the Purchase Date up to that number of
shares of Common Stock of the Company determined by dividing the amount
accumulated in such employee's payroll deduction account during such Purchase
Period by the lesser of (i) eighty-five percent (85%) of the fair market value
of a share of the Company's Common Stock on the Offering Date or (ii)
eighty-five percent (85%) of the fair market value of a share of the Company's
Common Stock on the Purchase Date; provided, however, that the number of shares
of the Company's Common Stock subject to any option granted pursuant to this
Plan shall not exceed the limitations provided under Sections 10(a) and 10(b)
below. Fair market value of a share of the Company's Common Stock shall be
determined as provided in Section 8 hereof.
<PAGE>

 8. PURCHASE PRICE

     The purchase price per share at which a share of Common Stock will be sold
during any Offering Period shall be eighty-five percent (85%) of the lesser of:

          (a) The fair market value on the Offering Date; or

          (b) The fair market value on the Purchase Date.

     For purposes of the Plan, the term "fair market value" on a given date
shall mean the closing price from the previous day's trading of a share of the
Company's Common Stock as reported on the National Association of Securities
Dealers Automated Quotation ("Nasdaq") System or such other system or exchange
to which the shares of the Company's Common Stock are admitted to trading or
quotation, as determined by the Administrator.

 9. PAYMENT OF PURCHASE PRICE; CHANGES IN PAYROLL DEDUCTIONS; ISSUANCE OF SHARES

     (a) The purchase price of the shares is accumulated by regular payroll
deductions made during each Purchase Period. The deductions are made as a
percentage of the participant's compensation in one percent (1%) increments not
less than one percent (1%) nor greater than fifteen percent (15%), not to exceed
$25,000 per year or such other limit set by the Administrator. Compensation
shall mean all cash compensation including, but not limited to, base salary,
wages, commissions, overtime, shift premiums and bonuses, plus draws against
commissions; provided, however, that for purposes of determining a participant's
compensation, any election by such participant to reduce his or her regular cash
remuneration under Sections 125 or 401(k) of the Code shall be treated as if the
participant did not make such election. Payroll deductions shall commence on the
first payday following the Offering Date and shall continue to the end of the
Purchase Period unless sooner altered or terminated as provided in the Plan.

     (b) A participant may decrease (but not increase) the rate of payroll
deductions during a Purchase Period by filing with the Treasury Department a new
authorization for payroll deductions, in which case the new rate shall become
effective for the next payroll period commencing more than fifteen (15) days
after the Treasury Department's receipt of the authorization and shall continue
for the remainder of the Purchase Period unless changed as described below. Such
change in the rate of payroll deductions may be made at any time during a
Purchase Period, but not more than one change may be made effective during any
Purchase Period. A participant may increase or decrease the rate of payroll
deductions for any subsequent Purchase Period by filing with the Treasury
Department a new authorization for payroll deductions not later than the
business day before the beginning of such Purchase Period. An increase or
decrease in a participant's payroll deduction does not start a new Offering
Period.

     (c) All payroll deductions made for a participant are credited to his or
her account under the Plan and are deposited with the general funds of the
Company. No interest accrues on the payroll deductions. All payroll deductions
received or held by the Company or a Subsidiary, respectively, may be used by
the Company or a Subsidiary, respectively, for any corporate purposes, and
neither the Company nor a Subsidiary shall be obligated to segregate such
payroll deductions.

     (d) On each Purchase Date, so long as the Plan remains in effect and
provided that the participant has not submitted a signed and completed
withdrawal form before that date which notifies the Company or a Subsidiary,
respectively, that the participant wishes to withdraw from that Purchase Period
under the Plan and have all payroll deductions accumulated in the account
maintained on behalf of the participant as of that date returned to the
participant, the Company shall apply the funds then in the participant's account
to the purchase of whole shares of Common Stock reserved under the option
granted to such participant with respect to the Purchase Period to the extent
that such option is exercisable on the Purchase Date. The purchase price per
share shall be as specified in Section 8 of the Plan. Any cash remaining in a
participant's account after such purchase of shares shall be refunded to such
participant in cash, without interest; provided, however, that any amount
remaining in such participant's account on a Purchase Date which is less than
the amount necessary to purchase a full share of Common Stock of the Company
shall be carried forward, without interest, into the next Purchase Period. In
the event that the Plan has been oversubscribed, all funds not used
<PAGE>

to purchase shares on the Purchase Date shall be returned to the participant,
without interest. No Common Stock shall be purchased on a Purchase Date on
behalf of any employee whose participation in the Plan has terminated prior to
such Purchase Date.

     (e) As promptly as practicable after the Purchase Date, the Company shall
arrange the delivery to each participant of a certificate representing the
shares purchased upon exercise of his or her option; provided, however, that the
Administrator may deliver certificates to a broker or brokers that hold such
certificate in a street name for the benefit of each such participant.

     (f) During a participant's lifetime, such participant's option to purchase
shares hereunder is exercisable only by him or her. The participant will have no
interest or voting right in shares covered by his or her option until such
option has been exercised. Shares to be delivered to a participant under the
Plan will be registered in the name of the participant or in the name of the
participant and his or her spouse.

10. LIMITATIONS ON SHARES TO BE PURCHASED

     (a) No employee shall be entitled to purchase stock under the Plan at a
rate which, when aggregated with his or her rights to purchase stock under all
other employee stock purchase plans of the Company or any Subsidiary, exceeds
$25,000 in fair market value, determined as of the Offering Date (or such other
limit as may be imposed by the Code) for each calendar year in which the
employee participates in the Plan.

     (b) No employee shall be entitled to purchase more than the Maximum Share
Amount (as defined below) on any single Purchase Date. Not less than thirty (30)
days prior to the commencement of any Purchase Period, the Administrator may, in
its sole discretion, set a maximum number of shares which may be purchased by
any employee at any single Purchase Date (hereinafter the "Maximum Share
Amount"). If a new Maximum Share Amount is set, then all participants must be
notified of such Maximum Share Amount not less than fifteen (15) days prior to
the commencement of the next Purchase Period. Once the Maximum Share Amount is
set, it shall continue to apply with respect to all succeeding Purchase Dates
and Purchase Periods unless revised by the Administrator as set forth above.

     (c) If the number of shares to be purchased on a Purchase Date by all
employees participating in the Plan exceeds the number of shares then available
for issuance under the Plan, the Company will make a pro rata allocation of the
remaining shares in as uniform a manner as shall be practicable and as the
Administrator shall determine to be equitable. In such event, the Company shall
give written notice of such reduction of the number of shares to be purchased
under a participant's option to each participant affected thereby.

     (d) Subject to the provisions of Section 9(d) hereof, any payroll
deductions accumulated in a participant's account which are not used to purchase
stock due to the limitations in this Section 10 shall be returned to the
participant as soon as practicable after the end of the Purchase Period, without
interest.

11. WITHDRAWAL

     (a) Each participant may withdraw from a Purchase Period under the Plan by
signing and delivering to the Treasury Department notice on a form provided for
such purpose. Such withdrawal may be elected at any time at least fifteen (15)
days prior to the end of a Purchase Period.

     (b) Upon withdrawal from the Plan, the accumulated payroll deductions shall
be returned to the withdrawn participant, without interest, and his or her
interest in the Plan shall terminate. In the event a participant voluntarily
elects to withdraw from the Plan, he or she may not resume his or her
participation in the Plan during the same Purchase Period, but he or she may
participate in any Purchase Period under the Plan which commences on a date
subsequent to such withdrawal by filing a new authorization for payroll
deductions in the same manner as set forth above for initial participation in
the Plan.

     (c) For an Offering Period in which a participant is enrolled, if the fair
market value of the Company's Common Stock on the Purchase Date is less than it
was on the Offering Date, the Company will automatically enroll such participant
in the subsequent Offering Period. A participant does not need to file any forms
with the Company to automatically be enrolled in the subsequent Offering Period.
<PAGE>

12. TERMINATION OF EMPLOYMENT

     Termination of a participant's employment for any reason, including
retirement, death or the failure of a participant to remain an eligible
employee, immediately terminates his or her participation in the Plan. In such
event, the payroll deductions credited to the participant's account will be
returned to him or her or, in the case of his or her death, to his or her legal
representative, without interest. For purposes of this Section 12, an employee
will not be deemed to have terminated employment or failed to remain in the
continuous employ of the Company in the case of sick leave, military leave, or
any other leave of absence approved by the Administrator; provided, however,
that such leave is for a period of not more than ninety (90) days or
reemployment upon the expiration of such leave is guaranteed by contract or
statute.

13. RETURN OF PAYROLL DEDUCTIONS

     In the event a participant's interest in the Plan is terminated by
withdrawal, termination of employment or otherwise, or in the event the Plan is
terminated by the Administrator, the Company shall promptly deliver to the
participant all payroll deductions credited to his or her account. No interest
shall accrue on the payroll deductions of a participant in the Plan.

14. CAPITAL CHANGES; CHANGE IN CONTROL

     Subject to any required action by the shareholders of the Company, the
number of shares of Common Stock covered by each option under the Plan which has
not yet been exercised and the number of shares of Common Stock which have been
authorized for issuance under the Plan but have not yet been placed under option
(collectively, the "Reserves"), as well as the price per share of Common Stock
covered by each option under the Plan which has not yet been exercised, shall be
proportionately adjusted for any increase or decrease in the number of issued
shares of Common Stock resulting from a stock split or the payment of a stock
dividend (but only on the Common Stock) or any other increase or decrease in the
number of 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 shall be final, binding and conclusive. Except as expressly
provided herein, no issue 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.

     In the event of a Change in Control of the Company, the Offering Periods
shall terminate on such date as determined by the Administrator and all payroll
deductions on such date shall be used to purchase such number of applicable
shares of Common Stock unless otherwise provided by the Administrator. For
purposes of this Plan, "Change in Control" means a change in the ownership or
control of the Company, effected through any of the following events:

          (a) any "person," as such term is used in Sections 13(d) and 14(d) of
     the Exchange Act (other than the Company; any trustee or other fiduciary
     holding securities under an employee benefit plan of the Company; or any
     company owned, directly or indirectly, by the shareholders of the Company
     in substantially the same proportions as their ownership of Common Stock of
     the Company) is or becomes, after the Effective Date (as defined in Section
     25 hereof), the "beneficial owner" (as defined in Rule 13d-3 under the
     Exchange Act), directly or indirectly, of securities of the Company (not
     including in the securities beneficially owned by such person any
     securities acquired directly from the Company or its affiliates)
     representing twenty-five percent (25%) or more of the combined voting power
     of the Company's then outstanding securities;

          (b) during any period of two consecutive years (not including any
     period prior to the Effective Date), individuals who at the beginning of
     such period constitute the Board, and any new director (other than a
     director designated by a person who has entered into an agreement with the
     Company to effect a transaction described in clause (a), (c) or (d) of this
     definition) whose election by the Board or nomination for election by the
     Company's shareholders was approved by a vote of at least two thirds ( 2/3)
     of the directors then still in office who either were directors at the
     beginning of the period or whose
<PAGE>

     election or nomination for election was previously so approved, cease for
     any reason to constitute at least a majority thereof;

          (c) the shareholders of the Company approve a merger or consolidation
     of the Company with any other corporation, other than (A) a merger or
     consolidation which would result in the voting securities of the Company
     outstanding immediately prior thereto continuing to represent (either by
     remaining outstanding or by being converted into voting securities of the
     surviving entity), in combination with the ownership of any trustee or
     other fiduciary holding securities under an employee benefit plan of the
     Company, at least sixty percent (60%) of the combined voting power of the
     voting securities of the Company or such surviving entity outstanding
     immediately after such merger or consolidation or (B) a merger or
     consolidation effected to implement a recapitalization of the Company (or
     similar transaction) in which no person acquires more than fifty percent
     (50%) of the combined voting power of the Company's then outstanding
     securities; or

          (d) the shareholders of the Company approve a plan of complete
     liquidation of the Company or an agreement for the sale or disposition by
     the Company of all or substantially all of the Company's assets.

     The Administrator may, if it so determines in the exercise of its sole
discretion, also make provision for adjusting the Reserves, as well as the price
per share of Common Stock covered by each outstanding option, in the event that
the Company effects one or more reorganizations, recapitalizations, rights
offerings or other increases or reductions of shares of its outstanding Common
Stock, or in the event of the Company being consolidated with or merged into any
other corporation.

15. NONASSIGNABILITY

     Neither payroll deductions credited to a participant's account nor any
rights with regard to the exercise of an option or to receive shares under the
Plan may be assigned, transferred, pledged or otherwise disposed of in any way
(other than by will, the laws of descent and distribution or as provided in
Section 22 hereof) by the participant. Any such attempt at assignment, transfer,
pledge or other disposition shall be without effect.

16. REPORTS

     Individual accounts will be maintained for each participant in the Plan.
Each participant shall receive promptly after the end of each Purchase Period a
report of his or her account setting forth the total payroll deductions
accumulated, the number of shares purchased, the per share price thereof and the
remaining cash balance, if any, carried forward to the next Purchase Period.

17. NOTICE OF DISPOSITION

     Each participant shall notify the Company if the participant disposes of
any of the shares of Common Stock purchased in any Purchase Period pursuant to
this Plan if such disposition occurs within two years from the Offering Date or
within one year from the Purchase Date on which such shares were purchased (the
"Notice Period"). Unless such participant is disposing of any of such shares
during the Notice Period, such participant shall keep the certificates
representing such shares in his or her name (and not in the name of a nominee)
during the Notice Period. The Company may, at any time during the Notice Period,
place a legend or legends on any certificate representing shares acquired
pursuant to the Plan requesting the Company's transfer agent to notify the
Company of any transfer of the shares. The obligation of the participant to
provide such notice shall continue notwithstanding the placement of any such
legend on the certificates.

18. NO RIGHTS TO CONTINUED EMPLOYMENT

     Neither this Plan nor the grant of any option hereunder shall confer any
right on any employee to remain in the employ of the Company or any Subsidiary,
or restrict the right of the Company or any Subsidiary to terminate such
employee's employment.
<PAGE>

19. EQUAL RIGHTS AND PRIVILEGES

     All eligible employees shall have equal rights and privileges with respect
to the Plan so that the Plan qualifies as an "employee stock purchase plan"
within the meaning of Section 423 or any successor provision of the Code and the
related regulations. Any provision of the Plan which is inconsistent with
Section 423 or any successor provision of the Code shall, without further act or
amendment by the Company or the Administrator, be reformed to comply with the
requirements of Section 423. This Section 19 shall take precedence over all
other provisions in the Plan.

20. NOTICES

     All notices or other communications by a participant to the Company under
or in connection with the Plan shall be deemed to have been duly given when
received in the form specified by the Company at the location, or by the person,
designated by the Company for the receipt thereof.

21. SHAREHOLDER APPROVAL OF AMENDMENTS

     Any required approval by the shareholders of the Company shall be solicited
substantially in accordance with Section 14(a) of the Exchange Act, and the
rules and regulations promulgated thereunder. Such approval of an amendment
shall be solicited at or prior to the first annual meeting of shareholders held
subsequent to the grant of an option under the Plan to an employee of the
Company. If such shareholder approval is obtained at a duly held shareholders'
meeting, it must be obtained by a majority of all of the outstanding shares of
the Company, or if such shareholder approval is obtained by written consent, it
must be obtained by a majority of all shareholders of the Company; provided,
however, that approval at a meeting or by written consent may be obtained by a
lesser degree of shareholder approval if the Administrator determines, in its
discretion after consultation with the Company's legal counsel, that such lesser
degree of shareholder approval will comply with all applicable laws and will not
adversely affect the qualification of the Plan under Section 423 of the Code or
Rule 16b-3 promulgated under the Exchange Act ("Rule 16b-3").

22. DESIGNATION OF BENEFICIARY

     (a) A participant may file a written designation of a beneficiary who is to
receive any shares and cash, if any, from the participant's account under the
Plan in the event of such participant's death subsequent to the end of a
Purchase Period but prior to delivery to him or her of such shares and cash. In
addition, a participant may file a written designation of a beneficiary who is
to receive any cash from the participant's account under the Plan in the event
of such participant's death prior to a Purchase Date.

     (b) Such designation of beneficiary may be changed by the participant at
any time by written notice. In the event of the death of a participant and in
the absence of a beneficiary validly designated under the Plan who is living at
the time of such participant's death, the Company shall deliver such shares or
cash to the executor or administrator of the estate of the participant, or if no
such executor or administrator has been appointed (to the knowledge of the
Company), the Company, in its discretion, may deliver such shares or cash to the
spouse or to any one or more dependents or relatives of the participant, or if
no spouse, dependent or relative is known to the Company, then to such other
person as the Company may designate.

23. CONDITIONS UPON ISSUANCE OF SHARES; LIMITATION ON SALE OF SHARES

     Shares shall not be issued with respect to an option unless the exercise of
such option and the issuance and delivery of such shares pursuant thereto shall
comply with all applicable provisions of law, domestic or foreign, including,
without limitation, the Securities Act of 1933, as amended, the Exchange Act,
the rules and regulations promulgated thereunder, and the requirements of any
stock exchange upon which the shares may then be listed, and shall be further
subject to the approval of counsel for the Company with respect to such
compliance.
<PAGE>

24. APPLICABLE LAW

     The Plan shall be governed by the substantive laws (excluding the conflict
of laws rules) of the State of California.

25. AMENDMENT OR TERMINATION OF THE PLAN

     This Plan shall be effective April 23, 2001 (the "Effective Date"), subject
to approval by the shareholders of the Company within twelve (12) months after
the date the Plan is adopted by the Board and the Plan shall continue until the
earlier to occur of termination by the Administrator, issuance of all of the
shares of Common Stock reserved for issuance under the Plan, or ten (10) years
from the adoption of the Plan by the Board. No purchase of shares of Common
Stock pursuant to the Plan shall occur prior to such shareholder approval. The
Administrator may at any time amend or terminate the Plan, except that any such
termination cannot affect options previously granted under the Plan, nor may any
amendment make any change in an option previously granted which would adversely
affect the right of any participant without such participant's consent, nor may
any amendment be made without approval of the shareholders of the Company
obtained in accordance with Section 21 hereof within 12 months of the adoption
of such amendment (or earlier if required by Section 21) if such amendment
would:

          (a) increase the number of shares that may be issued under the Plan;

          (b) change the designation of the employees (or class of employees)
     eligible for participation in the Plan; or

          (c) constitute an amendment for which shareholder approval is required
     in order to comply with Rule 16b-3 (or any successor rule) of the Exchange
     Act.
