      1.    PURPOSES.

            (a) ELIGIBLE STOCK AWARD RECIPIENTS. The persons eligible to receive
Stock Awards are the Employees, Directors and Consultants of the Company and its
Affiliates.

            (b) AVAILABLE STOCK AWARDS. The purpose of the Plan is to provide a
means by which eligible recipients of Stock Awards may be given an opportunity
to benefit from increases in value of the Common Stock through the granting of
the following Stock Awards: (i) Incentive Stock Options, (ii) Nonstatutory Stock
Options, (iii) stock bonuses and (iv) rights to acquire restricted stock.

            (c) GENERAL PURPOSE. The Company, by means of the Plan, seeks to
retain the services of the group of persons eligible to receive Stock Awards, to
secure and retain the services of new members of this group and to provide
incentives for such persons to exert maximum efforts for the success of the
Company and its Affiliates.

services or (ii) who is a member of the Board of Directors of an Affiliate.
However, the term "Consultant" shall not include either Directors of the Company
who are not compensated by the Company for their services as Directors or
Directors of the Company who are merely paid a director's fee by the Company for

            (h) "CONTINUOUS SERVICE" means that the Participant's service with
the Company or an Affiliate, whether as an Employee, Director or Consultant, is
not interrupted or terminated. The Participant's Continuous Service shall not be
deemed to have terminated merely because of 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 Continuous Service. For example, a change in status from an
Employee of the Company to a Consultant of an Affiliate or a Director of the
Company will not constitute an interruption of Continuous Service. The Board or
the chief executive officer of the Company, in that party's sole 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.

of the sickness or injury of the person.

            (l) "EMPLOYEE" means any person employed by the Company or an
Affiliate. Mere service as a Director or payment of a director's fee by the
Company or an Affiliate shall not be sufficient to constitute "employment" by
the Company or an Affiliate.

amended.

quoted on such exchange or market (or the exchange or market with the greatest
volume of trading in the Common Stock) on the last market trading day prior to
the day of determination, as reported in The Wall Street Journal or such other
source as the Board deems reliable.

securities exchange or designated (or approved for designation) upon notice of

unless and until the Board delegates administration to a Committee, as provided
in subsection 3(c).

            (b) POWERS OF BOARD. The Board shall have the power, subject to, and
within the limitations of, the express provisions of the Plan:

               (i) To determine from time to time which of the persons eligible
under the Plan shall be granted Stock Awards; when and how each Stock Award
shall be granted; what type or combination of types of Stock Award shall be
granted; the provisions of each Stock Award granted (which need not be

Plan fully effective.

               (iii) To amend the Plan or a Stock Award as provided in Section
12.

               (iv) Generally, to exercise such powers and to perform such acts
as the Board deems necessary or expedient to promote the best interests of the

            (c)   DELEGATION TO COMMITTEE.

               (i) GENERAL. The Board may delegate administration of the Plan to
a Committee or Committees of one or more members of the Board, and the term

have, in connection with the administration of the Plan, the powers theretofore
possessed by the Board, including the power to delegate to a subcommittee any of
the administrative powers the Committee is authorized to exercise (and
references in this Plan to the Board shall thereafter be to the Committee or

Stock Awards shall not exceed in the aggregate six million, five hundred
thousand (6,500,000) shares of Common Stock.

shall for any reason expire or otherwise terminate, in whole or in part, without
having been

                                                                             -5-
<PAGE>
exercised in full (or vested in the case of Restricted Stock), the
stock not acquired under such Stock Award shall revert to and again become
available for issuance under the Plan. If any Common Stock acquired pursuant to
the exercise of an Option shall for any reason be repurchased by the Company
under an unvested share repurchase option provided under the Plan, the stock
repurchased by the Company under such repurchase option shall not revert to and
again become available for issuance under the Plan.

            (c) SOURCE OF SHARES. The stock subject to the Plan may be unissued
shares or reacquired shares, bought on the market or otherwise.

may be granted only to Employees. Stock Awards other than Incentive Stock
Options may be granted to Employees, Directors and Consultants.

            (b) TEN PERCENT SHAREHOLDERS. No Ten Percent Shareholder shall be
eligible for the grant of an 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 at the date of grant and, in the case of an Incentive Stock Option, the
Option is not exercisable after the expiration of five (5) years from the date
of grant.

            No Ten Percent Shareholder shall be eligible for the grant of a
Nonstatutory 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 at
the date of grant.

            No Ten Percent Shareholder shall be eligible for a restricted stock
award unless the purchase price of the restricted stock is at least one hundred
percent (100%) of the Fair Market Value of the Common Stock at the date of
grant.

            (c) SECTION 162(m) LIMITATION. Subject to the provisions of Section
11 relating to adjustments upon changes in stock, no employee shall be eligible
to be granted Options covering more than seven hundred fifty thousand (750,000)
shares of the Common Stock during any calendar year. This subsection 5(c) shall
not apply prior to the Listing Date and, following the Listing Date, this
subsection 5(c) shall not apply until (i) the earliest of: (1) the first

shares reserved for issuance under the Plan in accordance with Section 4); (2)
the issuance of all of the shares of Common Stock reserved for issuance under
the Plan; (3) the expiration of the Plan; or (4) the first meeting of

the rules and regulations promulgated thereunder.

      6.    OPTION PROVISIONS.

            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

                                                                             -6-
<PAGE>
Nonstatutory Stock Options at the time of grant, and a separate certificate or
certificates will be issued for shares 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 the provisions of subsection 5(b) regarding Ten
Percent Shareholders, no Option shall be exercisable after the expiration of ten
(10) years from the date it was granted.

            (b) EXERCISE PRICE OF AN INCENTIVE STOCK OPTION. Subject to the
provisions of subsection 5(b) regarding Ten Percent Shareholders, the exercise
price of each Incentive Stock Option shall be not less than one hundred percent
(100%) of the Fair Market Value of the 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 the
provisions of subsection 5(b) regarding Ten Percent Shareholders, the exercise
price of each Nonstatutory Stock Option granted prior to the Listing Date shall
be not less than one hundred percent (100%) of the Fair Market Value of the
stock subject to the Option on the date the Option is granted. The exercise
price of each Nonstatutory Stock Option granted on or after the Listing Date
shall be not less than eighty-five percent (85%) of the Fair Market Value of the
stock subject to the Option on the date the Option is granted. Notwithstanding
the foregoing, a Nonstatutory 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.

            (d) CONSIDERATION. The purchase price of stock acquired pursuant to
an Option shall be paid, to the extent permitted by applicable statutes and
regulations, 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) by (1) delivery to the
Company of other Common Stock, (2) according to a deferred payment or other
arrangement (which may include, without limiting the generality of the
foregoing, the use of other Common Stock) with the Participant or (3) in any
other form of legal consideration that may be acceptable to the Board; provided,
however, that 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 any deferred payment arrangement, interest shall be
compounded at least annually and shall be charged at the minimum rate of
interest necessary to avoid the treatment as interest, under any applicable
provisions of the Code, of any amounts other than amounts stated to be interest
under the deferred payment arrangement.

            (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

                                                                             -7-
<PAGE>
shall be exercisable during the lifetime of the Optionholder only by the
Optionholder. Notwithstanding the foregoing provisions of this subsection 6(e),
the Optionholder may, by delivering written notice to the Company, in a form
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 granted prior to the Listing Date 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. A Nonstatutory
Stock Option granted on or after the Listing Date 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 provisions of this subsection 6(f), the
Optionholder may, by delivering written notice to the Company, in a form
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, but need not, vest and therefore become exercisable in
periodic installments which may, but need not, 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 subsection 6(g) are subject to any Option provisions
governing the minimum number of shares as to which an Option may be exercised.

            (h) MINIMUM VESTING PRIOR TO THE LISTING DATE. Notwithstanding the
foregoing subsection 6(g), Options shall provide for vesting of the total number
of shares at a rate of at least twenty percent (20%) per year over five (5)
years from the date the Option was granted, subject to reasonable conditions
such as continued employment. However, in the case of such Options granted to
Officers, Directors or Consultants, the Option may become fully exercisable,
subject to reasonable conditions such as continued employment, at any time or
during any period established by the Company; for example, the vesting provision
of the Option may provide for vesting of less than twenty percent (20%) per year
of the total number of shares subject to the Option.

            (i) TERMINATION OF CONTINUOUS SERVICE. In the event an
Optionholder's Continuous Service terminates (other than 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 it 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 Optionholder's
Continuous Service (or such longer or shorter period specified in the Option
Agreement, which shall not be less than thirty (30) days, unless such
termination is for cause), or (ii) the expiration of the term of the Option as
set forth in the Option Agreement. If, after termination, the Optionholder does
not exercise his or her Option within the time specified in the Option
Agreement, the Option shall terminate.

                                                                             -8-
<PAGE>
            (j) EXTENSION OF TERMINATION DATE. An Optionholder's Option
Agreement may also provide that if the exercise of the Option following the
termination of the Optionholder's Continuous Service (other than upon the
Optionholder's death or Disability) would be prohibited at any time solely
because the issuance of shares would violate the registration requirements under
the Securities Act, then the Option shall terminate on the earlier of (i) the
expiration of the term of the Option set forth in subsection 6(a) 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.

            (k) DISABILITY OF OPTIONHOLDER. In the event 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 it as of the date of termination), but only within such
period of time ending on the earlier of (i) the date twelve (12) months
following such termination (or such longer or shorter period specified in the
Option Agreement, which shall not be less than six (6) months) or (ii) the
expiration of the term of the Option as set forth in the Option Agreement. If,
after termination, the Optionholder does not exercise his or her Option within
the time specified herein, the Option shall terminate.

            (l) DEATH OF OPTIONHOLDER. In the event (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 the 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 subsection 6(e) or 6(f), but only within
the period ending on the earlier of (1) the date eighteen (18) months following
the date of death (or such longer or shorter period specified in the Option
Agreement, which shall not be less than six (6) months) or (2) the expiration of
the term of such Option as set forth in the Option Agreement. If, after death,
the Option is not exercised within the time specified herein, the Option shall
terminate.

            (m) EARLY EXERCISE. The Option may, but need not, 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 subject to the Option prior to the full vesting of the
Option. Subject to the "Repurchase Limitation" in subsection 10(h), any unvested
shares so purchased may be subject to an unvested share repurchase option in
favor of the Company or to any other restriction the Board determines to be
appropriate.

            (n) RIGHT OF REPURCHASE. Subject to the "Repurchase Limitation" in
subsection 10(h), the Option may, but need not, include a provision whereby the
Company may elect, prior to the Listing Date, to repurchase all or any part of
the vested shares acquired by the Optionholder pursuant to the exercise of the
Option.

            (o) RIGHT OF FIRST REFUSAL. The Option may, but need not, include a
provision whereby the Company may elect, prior to the Listing Date, to exercise
a right of first

                                                                             -9-

refusal following receipt of notice from the Optionholder of the intent to
transfer all or any part of the shares exercised pursuant to the Option.

      7.    PROVISIONS OF STOCK AWARDS OTHER THAN OPTIONS.

            (a) STOCK BONUS AWARDS. Each stock bonus 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 bonus agreements may change from
time to time, and the terms and conditions of separate stock bonus agreements
need not be identical, but each stock bonus 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 shall be awarded in
consideration for past services actually rendered to the Company for its
benefit.

                (ii) VESTING. Subject to the "Repurchase Limitation" in
subsection 10(h), shares of Common Stock awarded under the stock bonus agreement
may, but need not, be subject to a share repurchase option in favor of the
Company in accordance with a vesting schedule to be determined by the Board.

                (iii) TERMINATION OF PARTICIPANT'S CONTINUOUS SERVICE. Subject
to the "Repurchase Limitation" in subsection 10(h), in the event a Participant's
Continuous Service terminates, the Company may reacquire any or all of the
shares of Common Stock held by the Participant which have not vested as of the
date of termination under the terms of the stock bonus agreement.

                (iv) TRANSFERABILITY. For a stock bonus award made before the
Listing Date, rights to acquire shares under the stock bonus agreement shall not
be transferable except by will or by the laws of descent and distribution and
shall be exercisable during the lifetime of the Participant only by the
Participant. For a stock bonus award made on or after the Listing Date, rights
to acquire shares under the stock bonus agreement shall be transferable by the
Participant only upon such terms and conditions as are set forth in the stock
bonus agreement, as the Board shall determine in its discretion, so long as
stock awarded under the stock bonus agreement remains subject to the terms of
the stock bonus agreement.

            (b) RESTRICTED STOCK AWARDS. Each restricted stock purchase
agreement shall be in such form and shall contain such terms and conditions as
the Board shall deem appropriate. The terms and conditions of the restricted
stock purchase agreements may change from time to time, and the terms and
conditions of separate restricted stock purchase agreements need not be
identical, but each restricted stock purchase agreement shall include (through
incorporation of provisions hereof by reference in the agreement or otherwise)
the substance of each of the following provisions:

                (i) PURCHASE PRICE. Subject to the provisions of subsection 5(b)
regarding Ten Percent Shareholders, the purchase price under each restricted
stock purchase agreement shall be such amount as the Board shall determine and
designate in such restricted stock

                                                                            -10-
<PAGE>
purchase agreement. For restricted stock awards, the purchase price shall not be
less than one hundred percent (100%) of the stock's Fair Market Value on the
date such award is made or at the time the purchase is consummated.

            (ii) CONSIDERATION. The purchase price of stock acquired pursuant to
the restricted stock purchase agreement shall be paid either: (i) in cash at the
time of purchase; (ii) at the discretion of the Board, according to a deferred
payment or other arrangement with the Participant; or (iii) in any other form of
legal consideration that may be acceptable to the Board in its discretion;
provided, however, that at any time that the Company is incorporated in
Delaware, then payment of the Common Stock's "par value," as defined in the
Delaware General Corporation Law, shall not be made by deferred payment.

            (iii) VESTING. Subject to the "Repurchase Limitation" in subsection
10(h), shares of Common Stock acquired under the restricted stock purchase
agreement may, but need not, be subject to a share repurchase 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. Subject to the
"Repurchase Limitation" in subsection 10(h), in the event a Participant's
Continuous Service terminates, the Company may repurchase or otherwise reacquire
any or all of the shares of Common Stock held by the Participant which have not
vested as of the date of termination under the terms of the restricted stock
purchase agreement.

            (v) TRANSFERABILITY. For a restricted stock award made before the
Listing Date, rights to acquire shares under the restricted stock purchase
agreement shall not be transferable except by will or by the laws of descent and
distribution and shall be exercisable during the lifetime of the Participant
only by the Participant. For a restricted stock award made on or after the
Listing Date, rights to acquire shares under the restricted stock purchase
agreement shall be transferable by the Participant only upon such terms and
conditions as are set forth in the restricted stock purchase agreement, as the
Board shall determine in its discretion, so long as stock awarded under the
restricted stock purchase agreement remains subject to the terms of the
restricted stock purchase agreement.

      8.    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 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

                                                                            -11-
<PAGE>
lawful issuance and sale of stock under the Plan, the Company shall be relieved
from any liability for failure to issue and sell stock upon exercise of such
Stock Awards unless and until such authority is obtained.

      9.    USE OF PROCEEDS FROM STOCK.

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

      10.   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.

            (b) SHAREHOLDER 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
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 or
any instrument executed or Stock Award granted pursuant thereto shall confer
upon any Participant or other holder of Stock Awards 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 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 which exceed such limit (according to the order in which they
were granted) shall be treated as Nonstatutory Stock Options.

            (e) INVESTMENT ASSURANCES. The Company may require a Participant, as
a condition of exercising or acquiring 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

                                                                            -12-
<PAGE>
that the Participant is acquiring the stock subject to the Stock Award for the
Participant's own account and not with any present intention of selling or
otherwise distributing the stock. The foregoing requirements, and any assurances
given pursuant to such requirements, shall be inoperative if (iii) the issuance
of the shares upon the exercise or acquisition of stock under the Stock Award
has been registered under a then currently effective registration statement
under the Securities Act or (iv) as to any particular requirement, a
determination is made by counsel for the Company that such requirement need not
be met in the circumstances under the then applicable securities laws. The
Company may, upon advice of counsel to the Company, place legends on stock
certificates issued under the Plan as such counsel deems necessary or
appropriate in order to comply with applicable securities laws, including, but
not limited to, legends restricting the transfer of the stock.

            (f) WITHHOLDING OBLIGATIONS. To the extent provided by the terms of
a Stock Award Agreement, the Participant may satisfy any federal, state or local
tax withholding obligation relating to the exercise or acquisition of stock
under 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) tendering a cash payment; (ii)
authorizing the Company to withhold shares from the shares of the Common Stock
otherwise issuable to the participant as a result of the exercise or acquisition
of stock under the Stock Award; or (iii) delivering to the Company owned and
unencumbered shares of the Common Stock.

            (g) INFORMATION OBLIGATION. To the extent required by Section
260.140.46 of Title 10 of the California Code of Regulations, the Company shall
deliver financial statements to Participants at least annually. This subsection
10(g) shall not apply to key Employees whose duties in connection with the
Company assure them access to equivalent information.

            (h) REPURCHASE LIMITATION. The terms of any repurchase option shall
be specified in the Stock Award and may be either at Fair Market Value at the
time of repurchase or at not less than the original purchase price. To the
extent required by Section 260.140.41 and Section 260.140.42 of Title 10 of the
California Code of Regulations, any repurchase option contained in a Stock Award
shall be upon the terms described below:

            (i) FAIR MARKET VALUE. If the repurchase option gives the Company
the right to repurchase the shares upon termination of employment at not less
than the Fair Market Value of the shares to be purchased on the date of
termination of Continuous Service, then (i) the right to repurchase shall be
exercised for cash or cancellation of purchase money indebtedness for the shares
within ninety (90) days of termination of Continuous Service (or in the case of
shares issued upon exercise of Stock Awards after such date of termination,
within ninety (90) days after the date of the exercise) or such longer period as
may be agreed to by the Company and the Participant (for example, for purposes
of satisfying the requirements of Section 1202(c)(3) of the Code regarding
"qualified small business stock") and (ii) the right terminates when the shares
become publicly traded.

            (ii) ORIGINAL PURCHASE PRICE. If the repurchase option gives the
Company the right to repurchase the shares upon termination of Continuous
Service at the original

                                                                            -13-
<PAGE>
purchase price, then (i) the right to repurchase at the original purchase price
shall lapse at the rate of at least twenty percent (20%) of the shares per year
over five (5) years from the date the Stock Award is granted (without respect to
the date the Stock Award was exercised or became exercisable) and (ii) the right
to repurchase shall be exercised for cash or cancellation of purchase money
indebtedness for the shares within ninety (90) days of termination of Continuous
Service (or in the case of shares issued upon exercise of Options after such
date of termination, within ninety (90) days after the date of the exercise) or
such longer period as may be agreed to by the Company and the Participant (for
example, for purposes of satisfying the requirements of Section 1202(c)(3) of
the Code regarding "qualified small business stock").

      11.   ADJUSTMENTS UPON CHANGES IN STOCK.

            (a) CAPITALIZATION ADJUSTMENTS. If any change is made in the 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), the Plan will be appropriately
adjusted in the class(es) and maximum number of securities subject to the Plan
pursuant to subsection 4(a) and the maximum number of securities subject to
award to any person pursuant to subsection 5(c), and the outstanding Stock
Awards will be appropriately adjusted in the class(es) and number of securities
and price per share of stock subject to such outstanding Stock Awards. The
Board, the determination of which shall be final, binding and conclusive, shall
make such adjustments. (The conversion of any convertible securities of the
Company shall not be treated as a transaction "without receipt of consideration"
by the Company.)

            (b) CHANGE IN CONTROL -- DISSOLUTION OR LIQUIDATION. In the event of
a dissolution or liquidation of the Company, then such Stock Awards shall be
terminated if not exercised (if applicable) prior to such event.

            (c) CHANGE IN CONTROL -- ASSET SALE, MERGER, CONSOLIDATION OR
REVERSE MERGER. In the event of (i) a sale of fifty percent (50%) or more of the
assets of the Company, (ii) a merger or consolidation in which the Company is
not the surviving corporation, or (iii) a reverse merger in which the Company is
the surviving corporation but the shares of Common Stock outstanding immediately
preceding the merger are converted by virtue of the merger into other property,
whether in the form of securities, cash or otherwise, then any surviving
corporation or acquiring corporation shall assume any Stock Awards outstanding
under the Plan or shall substitute similar stock awards for those outstanding
under the Plan (including an award to acquire the same consideration paid to the
shareholders in the transaction described in this subsection 11(c)). In the
event any surviving corporation or acquiring corporation refuses to assume such
Stock Awards or to substitute similar stock awards for those outstanding under
the Plan, then with respect to Stock Awards held by Participants whose
Continuous Service has not terminated, the vesting of such Stock Awards (and, if
applicable, the time during which such Stock Awards may be exercised) shall be
accelerated in full, and the Stock Awards shall terminate if not exercised (if
applicable) at or prior to such event. With respect to any other Stock Awards
outstanding under the Plan, such Stock Awards shall terminate if not exercised
(if applicable) prior to such event.

                                                                            -14-
<PAGE>
            (d) CHANGE IN CONTROL -- SECURITIES ACQUISITION. After the Listing
Date, in the event of an acquisition by any person, entity or group within the
meaning of Section 13(d) or 14(d) of the Exchange Act, or any comparable
successor provisions (excluding any employee benefit plan, or related trust,
sponsored or maintained by the Company or an Affiliate) of the beneficial
ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act,
or comparable successor rule) of securities of the Company representing at least
fifty percent (50%) of the combined voting power entitled to vote in the
election of directors, then any surviving corporation or acquiring corporation
shall assume any Stock Awards outstanding under the Plan or shall substitute
similar stock awards for those outstanding under the Plan. In the event any
surviving or acquiring corporation refuses to assume such Stock Awards or to
substitute similar stock awards for those outstanding under the Plan, then with
respect to Stock Awards held by Participants whose Continuous Service has not
terminated, the vesting of such Stock Awards (and, if applicable, the time
during which such Stock Awards may be exercised) shall be accelerated in full,
and the Stock Awards shall terminate if not exercised (if applicable) at or
prior to such event. With respect to any other Stock Awards outstanding under
the Plan, such Stock Awards shall terminate if not exercised (if applicable)
prior to such event.

      12.   AMENDMENT OF THE PLAN AND STOCK AWARDS.

            (a) AMENDMENT OF PLAN. The Board at any time, and from time to time,
may amend the Plan. However, except as provided in Section 11 relating to
adjustments upon changes in stock, no amendment shall be effective unless
approved by the shareholders of the Company to the extent shareholder approval
is necessary to satisfy the requirements of Section 422 of the Code, Rule 16b-3
or any Nasdaq or securities exchange listing requirements.

            (b) SHAREHOLDER APPROVAL. The Board may, in its sole discretion,
submit any other amendment to the Plan for shareholder 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 certain executive officers.

            (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; 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.

                                                                            -15-
<PAGE>
      13.   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 shareholders 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.

      The Plan shall become effective as determined by the Board, 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 shareholders of the Company,
which approval shall be within twelve (12) months before or after the date the
Plan is adopted by the Board.

                                                                            -16-

            (b) Any provisions of the Plan to the contrary notwithstanding, no
Employee shall be granted an option under the Plan (i) to the extent that,
immediately after the grant, such Employee (or any other person whose stock
would be attributed to such Employee pursuant to Section 424(d) of the Code)

      4. Offering Periods. The Plan shall be implemented by consecutive Offering
Periods with a new Offering Period commencing on the first Trading Day on or

Plan shall commence with the first Trading Day on or after the date on which the
Securities and Exchange Commission declares the Company's Registration Statement

Board shall have the power to change the duration of Offering Periods (including
the commencement dates thereof) with respect to future offerings without
stockholder approval if such change is announced at least five (5) days prior to
the scheduled beginning of the first Offering Period to be affected thereafter.

      5. Participation.

            (a) An eligible Employee may become a participant in the Plan by
completing a subscription agreement authorizing payroll deductions in the form
of Exhibit A to this Plan and filing it with the Company's payroll office prior
to the applicable Enrollment Date.

            (b) Payroll deductions for a participant shall commence on the first
payroll following the Enrollment Date and shall end on the last payroll in the
Offering Period to which such authorization is applicable, unless sooner
terminated by the participant as provided in Section 10 hereof.

      6. Payroll Deductions.

            (a) At the time a participant files his or her subscription
agreement, he or she shall elect to have payroll deductions made on each pay day
during the Offering Period in an amount not exceeding fifteen percent (15%) of
the Compensation which he or she receives on each pay day during the Offering
Period.

                                                                             -3-
<PAGE>
            (b) All payroll deductions made for a participant shall be credited
to his or her account under the Plan and shall be withheld in whole percentages
only. A participant may not make any additional payments into such account.

            (c) A participant may discontinue his or her participation in the
Plan as provided in Section 10 hereof, or may increase or decrease the rate of
his or her payroll deductions during the Offering Period by completing or filing
with the Company a new subscription agreement authorizing a change in payroll
deduction rate. The Board may, in its discretion, limit the number of
participation rate changes during any Offering Period. The change in rate shall
be effective with the first full payroll period following five (5) business days
after the Company's receipt of the new subscription agreement unless the Company
elects to process a given change in participation more quickly. A participant's
subscription agreement shall remain in effect for successive Offering Periods
unless terminated as provided in Section 10 hereof.

            (d) Notwithstanding the foregoing, to the extent necessary to comply
with Section 423(b)(8) of the Code and Section 3(b) hereof, a participant's
payroll deductions may be decreased to zero percent (0%) at any time during an
Offering Period. Payroll deductions shall recommence at the rate provided in
such participant's subscription agreement at the beginning of the first Offering
Period which is scheduled to end in the following calendar year, unless
terminated by the participant as provided in Section 10 hereof.

            (e) At the time the option is exercised, in whole or in part, or at
the time some or all of the Company's Common Stock issued under the Plan is
disposed of, the participant must make adequate provision for the Company's
federal, state, or other tax withholding obligations, if any, which arise upon
the exercise of the option or the disposition of the Common Stock. At any time,
the Company may, but shall not be obligated to, withhold from the participant's
compensation the amount necessary for the Company to meet applicable withholding
obligations, including any withholding required to make available to the Company
any tax deductions or benefits attributable to sale or early disposition of
Common Stock by the Employee.

      7. Grant of Option. On the Enrollment Date of each Offering Period, each
eligible Employee participating in such Offering Period shall be granted an
option to purchase on the Exercise Date of such Offering Period (at the
applicable Purchase Price) up to a number of shares of the Company's Common
Stock determined by dividing such Employee's payroll deductions accumulated
prior to such Exercise Date and retained in the Participant's account as of the
Exercise Date by the applicable Purchase Price; provided that in no event shall
an Employee be permitted to purchase during each Offering Period more than 5,000
shares (subject to any adjustment pursuant to Section 19), and provided further
that such purchase shall be subject to the limitations set forth in Sections
3(b) and 12 hereof. Exercise of the option shall occur as provided in Section 8
hereof, unless the participant has withdrawn pursuant to Section 10 hereof. The
Option shall expire on the last day of the Offering Period.

      8. Exercise of Option. Unless a participant withdraws from the Plan as
provided in Section 10 hereof, his or her option for the purchase of shares
shall be exercised automatically on the Exercise Date, and the maximum number of
full shares subject to option shall be purchased for such participant at the
applicable Purchase Price with the accumulated payroll deductions in his or her

                                                                             -4-
<PAGE>
account. No fractional shares shall be purchased; any payroll deductions
accumulated in a participant's account which are not sufficient to purchase a
full share shall be retained in the participant's account for the subsequent
Offering Period, subject to earlier withdrawal by the participant as provided in
Section 10 hereof. Any other monies left over in a participant's account after
the Exercise Date shall be returned to the participant. During a participant's
lifetime, a participant's option to purchase shares hereunder is exercisable
only by him or her.

      9. Delivery. As promptly as practicable after each Exercise Date on which
a purchase of shares occurs, the Company shall arrange the delivery to each
participant, as appropriate, the shares purchased upon exercise of his or her
option.

      10. Withdrawal.

            (a) A participant may withdraw all but not less than all the payroll
deductions credited to his or her account and not yet used to exercise his or
her option under the Plan at any time by giving written notice to the Company in
the form of Exhibit B to this Plan. All of the participant's payroll deductions
credited to his or her account shall be paid to such participant promptly after
receipt of notice of withdrawal and such participant's option for the Offering
Period shall be automatically terminated, and no further payroll deductions for
the purchase of shares shall be made for such Offering Period. If a participant
withdraws from an Offering Period, payroll deductions shall not resume at the
beginning of the succeeding Offering Period unless the participant delivers to
the Company a new subscription agreement.

            (b) A participant's withdrawal from an Offering Period shall not
have any effect upon his or her eligibility to participate in any similar plan
which may hereafter be adopted by the Company or in succeeding Offering Periods
which commence after the termination of the Offering Period from which the
participant withdraws.

      11. Termination of Employment. Upon a participant's ceasing to be an
Employee for any reason, he or she shall be deemed to have elected to withdraw
from the Plan and the payroll deductions credited to such participant's account
during the Offering Period but not yet used to exercise the option shall be
returned to such participant or, in the case of his or her death, to the person
or persons entitled thereto under Section 15 hereof, and such participant's
option shall be automatically terminated. The preceding sentence
notwithstanding, a participant who receives payment in lieu of notice of
termination of employment shall be treated as continuing to be an Employee for
the participant's customary number of hours per week of employment during the
period in which the participant is subject to such payment in lieu of notice.

      12. Interest. No interest shall accrue on the payroll deductions of a
participant in the Plan.

      13. Stock.

      (a) Subject to adjustment upon changes in capitalization of the Company as
provided in Section 19 hereof, the maximum number of shares of the Company's
Common Stock which shall be made available for sale under the Plan shall be
560,000 shares.

                                                                             -5-
<PAGE>
            (b) The participant shall have no interest or voting right in shares
covered by his option until such option has been exercised.

            (c) Shares to be delivered to a participant under the Plan shall be
registered in the name of the participant or in the name of the participant and
his or her spouse.

      14. Administration. The Plan shall be administered by the Board or a
committee of members of the Board appointed by the Board. The Board or its
committee shall have full and exclusive discretionary authority to construe,
interpret and apply the terms of the Plan, to determine eligibility and to
adjudicate all disputed claims filed under the Plan. Every finding, decision and
determination made by the Board or its committee shall, to the full extent
permitted by law, be final and binding upon all parties.

      15. 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 an
Exercise Date on which the option is exercised but prior to delivery to such
participant 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 exercise of the option. If a participant is married and the designated
beneficiary is not the spouse, spousal consent shall be required for such
designation to be effective.

            (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 and/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 and/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.

      16. Transferability. 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 15 hereof) by the participant. Any such
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Company may treat such act as an election to withdraw
funds from an Offering Period in accordance with Section 10 hereof.

      17. Use of Funds. All payroll deductions received or held by the Company
under the Plan may be used by the Company for any corporate purpose, and the
Company shall not be obligated to segregate such payroll deductions.

      18. Reports. Individual accounts shall be maintained for each participant
in the Plan. Statements of account shall be given to participating Employees at
least annually, which statements

                                                                             -6-
<PAGE>
shall set forth the amounts of payroll deductions, the Purchase Price, the
number of shares purchased and the remaining cash balance, if any.

      19. Adjustments Upon Changes in Capitalization, Dissolution, Liquidation,
Merger or Asset Sale.

            (a) Changes in Capitalization. Subject to any required action by the
stockholders of the Company, the Reserves, the maximum number of shares each
participant may purchase per Offering Period (pursuant to Section 7), as well as
the price per share and the number of shares 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, reverse stock split, stock dividend,
combination or reclassification of 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 Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class,
shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of shares of Common Stock subject to an option.

            (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Offering Period then in progress
shall be shortened by setting a new Exercise Date (the "New Exercise Date"), and
shall terminate immediately prior to the consummation of such proposed
dissolution or liquidation, unless provided otherwise by the Board. The New
Exercise Date shall be before the date of the Company's proposed dissolution or
liquidation. The Board shall notify each participant in writing, at least ten
(10) business days prior to the New Exercise Date, that the Exercise Date for
the participant's option has been changed to the New Exercise Date and that the
participant's option shall be exercised automatically on the New Exercise Date,
unless prior to such date the participant has withdrawn from the Offering Period
as provided in Section 10 hereof.

            (c) Merger or Asset Sale. In the event of a proposed sale of all or
substantially all of the assets of the Company, or the merger of the Company
with or into another corporation, each outstanding option shall be assumed or an
equivalent option substituted by the successor corporation or a Parent or
Subsidiary of the successor corporation. In the event that the successor
corporation refuses to assume or substitute for the option, the Offering Period
then in progress shall be shortened by setting a new Exercise Date (the "New
Exercise Date"). The New Exercise Date shall be before the date of the Company's
proposed sale or merger. The Board shall notify each participant in writing, at
least ten (10) business days prior to the New Exercise Date, that the Exercise
Date for the participant's option has been changed to the New Exercise Date and
that the participant's option shall be exercised automatically on the New
Exercise Date, unless prior to such date the participant has withdrawn from the
Offering Period as provided in Section 10 hereof.

      20. Amendment or Termination.

                                                                             -7-
<PAGE>
            (a) The Board of Directors of the Company may at any time and for
any reason terminate or amend the Plan. Except as provided in Section 19 hereof,
no such termination can affect options previously granted, provided that an
Offering Period may be terminated by the Board of Directors on any Exercise Date
if the Board determines that the termination of the Offering Period or the Plan
is in the best interests of the Company and its stockholders. Except as provided
in Section 19 and Section 20 hereof, no amendment may make any change in any
option theretofore granted which adversely affects the rights of any
participant. To the extent necessary to comply with Section 423 of the Code (or
any other applicable law, regulation or stock exchange rule), the Company shall
obtain shareholder approval in such a manner and to such a degree as required.

            (b) Without stockholder consent and without regard to whether any
participant rights may be considered to have been "adversely affected," the
Board (or its committee) shall be entitled to change the Offering Periods, limit
the frequency and/or number of changes in the amount withheld during an Offering
Period, establish the exchange ratio applicable to amounts withheld in a
currency other than U.S. dollars, permit payroll withholding in excess of the
amount designated by a participant in order to adjust for delays or mistakes in
the Company's processing of properly completed withholding elections, establish
reasonable waiting and adjustment periods and/or accounting and crediting
procedures to ensure that amounts applied toward the purchase of Common Stock
for each participant properly correspond with amounts withheld from the
participant's Compensation, and establish such other limitations or procedures
as the Board (or its committee) determines in its sole discretion advisable
which are consistent with the Plan.

            (c) In the event the Board determines that the ongoing operation of
the Plan may result in unfavorable financial accounting consequences, the Board
may, in its discretion and, to the extent necessary or desirable, modify or
amend the Plan to reduce or eliminate such accounting consequence including, but
not limited to:

               (1) shortening any Offering Period so that Offering Period ends
on a new Exercise Date, including an Offering Period underway at the time of the
Board action; and

               (2) allocating shares.

      Such modifications or amendments shall not require stockholder approval or
the consent of any Plan participants.

      21. 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.

      22. Conditions Upon Issuance 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 Securities Exchange Act of 1934, as
amended, the rules and regulations promulgated thereunder, and the requirements
of any stock

                                                                             -8-
<PAGE>
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.

      As a condition to the exercise of an option, the Company may require the
person exercising such option to represent and warrant at the time of any such
exercise that the shares are being purchased only for investment and without any
present intention to sell or distribute such shares if, in the opinion of
counsel for the Company, such a representation is required by any of the
aforementioned applicable provisions of law.

      23. Term of Plan. The Plan shall become effective upon the earlier to
occur of its adoption by the Board of Directors or its approval by the
stockholders of the Company. It shall continue in effect for a term of ten (10)
years unless sooner terminated under Section 20 hereof.

                                                                             -9-

compensation the amount necessary to meet any applicable withholding obligation
including any withholding necessary to make available to the Company any tax
deductions or benefits attributable to sale or early disposition of Common Stock
by me. If I dispose of such shares at any time after the expiration of the

tax purposes as having received income only at the time of such disposition, and
that such income will be taxed as ordinary income only to the extent of an
amount equal to the lesser of (1) the excess of the fair market value of the
shares at the time of such disposition over the purchase price which I paid for
the shares, or (2) 15% of the fair market value of the shares on the first day
of the Offering Period. The remainder of the gain, if any, recognized on such
disposition will be taxed as capital gain.

      7. I hereby agree to be bound by the terms of the Employee Stock Purchase
Plan. The effectiveness of this Subscription Agreement is dependent upon my
eligibility to participate in the Employee Stock Purchase Plan.

      8. In the event of my death, I hereby designate the following as my
beneficiary(ies) to receive all payments and shares due me under the Employee
