issuance upon exercise of an Option but cease to be subject to such Option for
any reason other than exercise of such Option; (b) an Award granted hereunder

                           combination with, in tandem with, in replacement of,
                           or as alternatives to, other Awards under this Plan
                           or any other incentive or compensation plan of the
                           Company or any Parent or Subsidiary of the Company;

                  (g)      grant waivers of Plan or Award conditions;

                  (h)      determine the vesting, ability to exercise and

                  (i)      correct any defect, supply any omission or reconcile
                           any inconsistency in this Plan, any Award or any

         5.2 BOARD DISCRETION. Any determination made by the Board with respect
to any Award will be made at the time of grant of the Award or, unless in
contravention of any express term of this Plan or Award, at any later time, and
such determination will be final and binding on the Company and on all persons
having an interest in any Award under this Plan. The Board may delegate to one
or more officers of the Company the authority to grant an Award under this Plan
to Participants who are not Insiders of the Company.

6.       OPTIONS.

         The Board may grant Options to eligible persons and will determine
whether such Options will be Incentive Stock Options within the meaning of the
Code ("ISO") or Nonqualified Stock Options ("NQSO"), the number of Shares
subject to the Option, the Exercise Price of the Option, the period during which
the Option may be exercised, and all other terms and conditions of the Option,
subject to the following:

         6.1 FORM OF OPTION GRANT. Each Option granted under this Plan will be
evidenced by an Award Agreement that will expressly identify the Option as an
ISO or an NQSO (hereinafter referred to as the "STOCK OPTION AGREEMENT"), and
will be in such form and contain such provisions (which need not be the same for
each Participant) as the Board may from time to time approve, and which will
comply with and be subject to the terms and conditions of this Plan.

         6.2 DATE OF GRANT. The date of grant of an Option will be the date on
which the Board makes the determination to grant such Option, unless otherwise
specified by the Board. The Stock Option Agreement and a copy of this Plan will
be delivered to the Participant within a reasonable time after the granting of
the Option.

         6.3 EXERCISE PERIOD. Options may be exercisable within the times or
upon the events determined by the Board as set forth in the Stock Option
Agreement governing such Option; provided, however, that no Option will be
exercisable after the expiration of ten (10) years from the date the Option is

<PAGE>

granted; and provided further that no ISO granted to a person who directly or by
attribution owns more than ten percent (10%) of the total combined voting power
of all classes of stock of the Company or of any Parent or Subsidiary of the
Company ("TEN PERCENT STOCKHOLDER") will be exercisable after the expiration of
five (5) years from the date the ISO is granted. The Board also may provide for
Options to become exercisable at one time or from time to time, periodically or
otherwise, in such number of Shares or percentage of Shares as the Board
determines.

         6.4 EXERCISE PRICE. The Exercise Price of an Option will be determined
by the Board when the Option is granted and may be not less than 85% of the Fair
Market Value of the Shares on the date of grant; provided that: (a) the Exercise
Price of an ISO will be not less than 100% of the Fair Market Value of the
Shares on the date of grant; and (b) the Exercise Price of any ISO granted to a
Ten Percent Stockholder will not be less than 110% of the Fair Market Value of
the Shares on the date of grant. Payment for the Shares purchased may be made in
accordance with Section 9 of this Plan.

         6.5 METHOD OF EXERCISE. Options may be exercised only by delivery to
the Company of a written stock option exercise agreement (the "EXERCISE
AGREEMENT") in a form approved by the Board, (which need not be the same for
each Participant), stating the number of Shares being purchased, the
restrictions imposed on the Shares purchased under such Exercise Agreement, if
any, and such representations and agreements regarding Participant's investment
intent and access to information and other matters, if any, as may be required
or desirable 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.

         6.6 TERMINATION. Notwithstanding the exercise periods set forth in the
Stock Option Agreement, exercise of an Option will always be subject to the
following:

                 (a) If the Participant's service is Terminated for any reason
except death or Disability, then the Participant may exercise such Participant's
Options only to the extent that such Options would have been exercisable upon
the Termination Date no later than three (3) months after the Termination Date
(or such shorter or longer time period not exceeding five (5) years as may be
determined by the Board, with any exercise beyond three (3) months after the
Termination Date deemed to be an NQSO), but in any event, no later than the
expiration date of the Options.

                 (b) If the Participant's service is Terminated because of
Participant's death or Disability (or the Participant dies within three (3)
months after a Termination other than for Cause or because of Participant's
Disability), then Participant's Options may be exercised only to the extent that
such Options would have been exercisable by Participant on the Termination Date
and must be exercised by Participant (or Participant's legal representative or
authorized assignee) no later than twelve (12) months after the Termination Date
(or such shorter or longer time period not exceeding five (5) years as may be
determined by the Board, with any such exercise beyond (i) three (3) months
after the Termination Date when the Termination is for any reason other than the
Participant's death or Disability, or (ii) twelve (12) months after the
Termination Date when the Termination is for Participant's death or Disability,
deemed to be an NQSO), but in any event no later than the expiration date of the
Options.

                  (c) Notwithstanding the provisions in paragraph 6.6(a) above,
if a Participant's service is Terminated for Cause, neither the Participant, the
Participant's estate nor such other person who may then hold the Option shall be
entitled to exercise any Option with respect to any Shares whatsoever, after

<PAGE>

Termination, whether or not after Termination the Participant may receive
payment from the Company or Subsidiary for vacation pay, for services rendered
prior to Termination, for services rendered for the day on which Termination
occurs, for salary in lieu of notice, or for any other benefits. For the purpose
of this paragraph, Termination shall be deemed to occur on the date when the
Company dispatches notice or advice to the Participant that his service is
Terminated.

         6.7 LIMITATIONS ON EXERCISE. The Board may specify a reasonable minimum
number of Shares that may be purchased on any exercise of an Option, provided
that such minimum number will not prevent Participant from exercising the Option
for the full number of Shares for which it is then exercisable.

         6.8 LIMITATIONS ON ISO. The aggregate Fair Market Value (determined as
of the date of grant) of Shares with respect to which ISO are exercisable for
the first time by a Participant during any calendar year (under this Plan or
under any other incentive stock option plan of the Company, Parent or Subsidiary
of the Company) will not exceed $100,000. If the Fair Market Value of Shares on
the date of grant with respect to which ISO are exercisable for the first time
by a Participant during any calendar year exceeds $100,000, then the Options for
the first $100,000 worth of Shares to become exercisable in such calendar year
will be ISO and the Options for the amount in excess of $100,000 that become
exercisable in that calendar year will be NQSOs. 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 ISO, such different limit will be automatically
incorporated herein and will apply to any Options granted after the effective
date of such amendment.

         6.9 MODIFICATION, EXTENSION OR RENEWAL. The Board may modify, extend or
renew outstanding Options and authorize the grant of new Options in substitution
therefor, provided that any such action may not, without the written consent of
a Participant, impair any of such Participant's rights under any Option
previously granted. Any outstanding ISO that is modified, extended, renewed or
otherwise altered will be treated in accordance with Section 424(h) of the Code.
The Board may reduce the Exercise Price of outstanding Options without the
consent of Participants affected by a written notice to them; provided, however,
that the Exercise Price may not be reduced below the minimum Exercise Price that
would be permitted under Section 6.4 of this Plan for Options granted on the
date the action is taken to reduce the Exercise Price.

         6.10 NO DISQUALIFICATION. Notwithstanding any other provision in this
Plan, no term of this Plan relating to ISO will be interpreted, amended or
altered, nor will any discretion or authority granted under this Plan be
exercised, so as to disqualify this Plan under Section 422 of the Code or,
without the consent of the Participant affected, to disqualify any ISO under
Section 422 of the Code.

7.       STOCK AWARD.

                  A Stock Award is an offer by the Company to sell to an
eligible person Shares that may or may not be subject to restrictions. The Board
will determine to whom an offer will be made, the number of Shares the person
may purchase, the price to be paid (the "PURCHASE PRICE"), the restrictions to
which the Shares will be subject, and all other terms and conditions of the
Stock Award, subject to the following:

         7.1 FORM OF STOCK AWARD. All purchases under a Stock Award made
pursuant to this Plan will be evidenced by an Award Agreement (the "STOCK
PURCHASE AGREEMENT") that will be in such form (which need not be the same for

<PAGE>

each Participant) as the Board will from time to time approve, and will comply
with and be subject to the terms and conditions of this Plan. The offer of Stock
will be accepted by the Participant's execution and delivery of the Stock
Purchase Agreement and full payment for the Shares to the Company within thirty
(30) days from the date the Stock Purchase Agreement is delivered to the person.
If such person does not execute and deliver the Stock Purchase Agreement along
with full payment for the Shares to the Company within thirty (30) days, then
the offer will terminate, unless otherwise extended by the Board.

         7.2 PURCHASE PRICE. The Purchase Price of Shares sold pursuant to a
Stock Award will be determined by the Board on the date the Stock Award is
granted, except in the case of a sale to a Ten Percent Stockholder, in which
case the Purchase Price will be 100% of the Fair Market Value. Payment of the
Purchase Price must be made in accordance with Section 9 of this Plan.

         7.3 TERMS OF STOCK AWARDS. Stock Awards shall be subject to such
restrictions as the Board may impose. These restrictions may be based upon
completion of a specified number of years of service with the Company or upon
completion of the performance goals as set out in advance in the Participant's
individual Stock Purchase Agreement. Stock Awards may vary from Participant to
Participant and between groups of Participants. Prior to the grant of a Stock
Award, the Board shall: (a) determine the nature, length and starting date of
any Performance Period for the Stock Award; (b) select from among the
Performance Factors to be used to measure performance goals, if any; and (c)
determine the number of Shares that may be awarded to the Participant. Prior to
the payment of any Stock Award, the Board shall determine the extent to which
such Stock Award has been earned. Performance Periods may overlap and
Participants may participate simultaneously with respect to Stock Awards that
are subject to different Performance Periods and have different performance
goals and other criteria.

         7.4 TERMINATION DURING PERFORMANCE PERIOD. If a Participant is
Terminated during a Performance Period for any reason, then such Participant
will be entitled to payment (whether in Shares, cash or otherwise) with respect
to the Stock Award only to the extent earned as of the date of Termination in
accordance with the Stock Purchase Agreement, unless the Board determines
otherwise.

<PAGE>

8.       STOCK BONUSES.

         8.1 AWARDS OF STOCK BONUSES. A Stock Bonus is an award of Shares (which
may consist of Restricted Stock) for extraordinary services rendered to the
Company or any Parent or Subsidiary of the Company. A Stock Bonus will be
awarded pursuant to an Award Agreement (the "STOCK BONUS AGREEMENT") that will
be in such form (which need not be the same for each Participant) as the Board
will from time to time approve, and will comply with and be subject to the terms
and conditions of this Plan. A Stock Bonus may be awarded upon satisfaction of
such performance goals as are set out in advance in the Participant's individual
Award Agreement (the "PERFORMANCE STOCK BONUS AGREEMENT") that will be in such
form (which need not be the same for each Participant) as the Board will from
time to time approve, and will comply with and be subject to the terms and
conditions of this Plan. Stock Bonuses may vary from Participant to Participant
and between groups of Participants, and may be based upon the achievement of the
Company, Parent or Subsidiary and/or individual performance factors or upon such
other criteria as the Board may determine.

         8.2 TERMS OF STOCK BONUSES. The Board will determine the number of
Shares to be awarded to the Participant. If the Stock Bonus is being earned upon
the satisfaction of performance goals pursuant to a Performance Stock Bonus
Agreement, then the Board will: (a) determine the nature, length and starting
date of any Performance Period for each Stock Bonus; (b) select from among the
Performance Factors to be used to measure the performance, if any; and (c)
determine the number of Shares that may be awarded to the Participant. Prior to
the payment of any Stock Bonus, the Board shall determine the extent to which
such Stock Bonuses have been earned. Performance Periods may overlap and
Participants may participate simultaneously with respect to Stock Bonuses that
are subject to different Performance Periods and different performance goals and
other criteria. The number of Shares may be fixed or may vary in accordance with
such performance goals and criteria as may be determined by the Board. The Board
may adjust the performance goals applicable to the Stock Bonuses to take into
account changes in law and accounting or tax rules and to make such adjustments
as the Board deems necessary or appropriate to reflect the impact of
extraordinary or unusual items, events or circumstances to avoid windfalls or
hardships.

         8.3 FORM OF PAYMENT. The earned portion of a Stock Bonus may be paid to
the Participant by the Company either currently or on a deferred basis, with
such interest or dividend equivalent, if any, as the Board may determine.
Payment may be made in the form of cash or whole Shares or a combination
thereof, either in a lump sum payment or in installments, all as the Board will
determine.

9.       PAYMENT FOR SHARE PURCHASES.

         9.1 PAYMENT. Payment for Shares purchased pursuant to this Plan may be
made in cash (by check) or, where expressly approved for the Participant by the
Board and where permitted by law:

                  (a)      by cancellation of indebtedness of the Company to the
                           Participant;

                  (b)      by surrender of shares that either: (1) have been
                           owned by Participant for more than one year and have
                           been paid for within the meaning of Rule 144 of the
                           Securities Act of 1933 (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 (2) were obtained by Participant in
                           the public market;

<PAGE>

                  (c)      by waiver of compensation due or accrued to the
                           Participant for services rendered;

                  (d)      with respect only to purchases upon exercise of an
                           Option, and provided that a public market for the
                           Company's stock exists:

                           (1)      through a "same day sale" commitment from
                                    the Participant and a broker-dealer that is
                                    a member of the National Association of
                                    Securities Dealers (an "NASD DEALER")
                                    whereby the Participant irrevocably elects
                                    to exercise the 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; or

                           (2)      through a "margin" commitment from the
                                    Participant and a NASD Dealer whereby the
                                    Participant irrevocably elects to exercise
                                    the 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; or

                  (e)      by any combination of the foregoing.


10.      WITHHOLDING TAXES.

         10.1 WITHHOLDING GENERALLY. Whenever Shares are to be issued in
satisfaction of Awards granted under this Plan, the Company may require the
Participant to remit to the Company an amount sufficient to satisfy federal,
state and local withholding tax requirements prior to the delivery of any
certificate or certificates for such Shares. Whenever, under this Plan, payments
in satisfaction of Awards are to be made in cash, such payment will be net of an
amount sufficient to satisfy federal, state, and local withholding tax
requirements.

         10.2 STOCK WITHHOLDING. When, under applicable tax laws, a participant
incurs tax liability in connection with the exercise or vesting of any Award
that is subject to tax withholding and the Participant is obligated to pay the
Company the amount required to be withheld, the Board may allow the Participant
to satisfy the minimum withholding tax obligation by electing to have the
Company withhold from the Shares to be issued that number of Shares having a
Fair Market Value equal to the minimum amount required to be withheld,
determined on the date that the amount of tax to be withheld is to be
determined. All elections by a Participant to have Shares withheld for this
purpose will be made in accordance with the requirements established by the
Board and be in writing in a form acceptable to the Board.

<PAGE>

11.      PRIVILEGES OF STOCK OWNERSHIP.

         11.1 VOTING AND DIVIDENDS. No Participant will have any of the rights
of a stockholder with respect to any Shares until the Shares are issued to the
Participant. After Shares are issued to the Participant, the Participant will be
a stockholder and will have all the rights of a stockholder with respect to such
Shares, including the right to vote and receive all dividends or other
distributions made or paid with respect to such Shares; provided, that if such
Shares are Restricted Stock, then any new, additional or different securities
the Participant may become entitled to receive with respect to such Shares by
virtue of a stock dividend, stock split or any other change in the corporate or
capital structure of the Company will be subject to the same restrictions as the
Restricted Stock; provided, further, that the Participant will have no right to
retain such stock dividends or stock distributions with respect to Shares that
are repurchased at the Participant's Purchase Price or Exercise Price pursuant
to Section 12.

         11.2 FINANCIAL STATEMENTS. Pursuant to regulation 260.140.46 of the
Rules of the California Corporations Commissioner, the Company will provide
financial statements to each Participant prior to such Participant's purchase of
Shares under this Plan, and to each Participant annually during the period such
Participant has Awards outstanding; provided, however, the Company will not be
required to provide such financial statements to Participants whose services in
connection with the Company assure them access to equivalent information.

12.      TRANSFERABILITY.

         Awards granted under this Plan, and any interest therein, will not be
transferable or assignable by Participant, and may not be made subject to
execution, attachment or similar process, other than by will or by the laws of
descent and distribution. During the lifetime of the Participant an Award will
be exercisable only by the Participant. During the lifetime of the Participant,
any elections with respect to an Award may be made only by the Participant
unless otherwise determined by the Board and set forth in the Award Agreement
with respect to Awards that are not ISOs.

13.      RESTRICTIONS ON SHARES.

         At the discretion of the Board, the Company may reserve to itself
and/or its assignee(s) in the Award Agreement a right to repurchase a portion of
or all Unvested Shares held by a Participant following such Participant's
Termination at any time within ninety (90) days after the later of (a)
Participant's Termination Date, or (b) the date Participant purchases Shares
under this Plan. Such repurchase by the Company shall be for cash and/or
cancellation of purchase money indebtedness, and the price per share shall be
the Participant's Exercise Price or the Purchase Price, as applicable.

<PAGE>

14.      CERTIFICATES.

         All certificates for Shares or other securities delivered under this
Plan will be subject to such stock transfer orders, legends and other
restrictions as the Board may deem necessary or advisable, including
restrictions under any applicable federal, state or foreign securities law, or
any rules, regulations and other requirements of the SEC or any stock exchange
or automated quotation system upon which the Shares may be listed or quoted.

15.      ESCROW; PLEDGE OF SHARES.

         To enforce any restrictions on a Participant's Shares, the Board may
require the Participant to deposit all certificates representing Shares,
together with stock powers or other instruments of transfer approved by the
Board appropriately endorsed in blank, with the Company or an agent designated
by the Company to hold in escrow until such restrictions have lapsed or
terminated, and the Board may cause a legend or legends referencing such
restrictions to be placed on the certificates. Any Participant who is permitted
to execute a promissory note as partial or full consideration for the purchase
of Shares under this Plan will be required to pledge and deposit with the
Company all or part of the Shares so purchased as collateral to secure the
payment of Participant's obligation to the Company under the promissory note;
provided, however, that the Board may require or accept other or additional
forms of collateral to secure the payment of such obligation and, in any event,
the Company will have full recourse against the Participant under the promissory
note notwithstanding any pledge of the Participant's Shares or other collateral.
In connection with any pledge of the Shares, Participant will be required to
execute and deliver a written pledge agreement in such form as the Board will
from time to time approve. The Shares purchased with the promissory note may be
released from the pledge on a pro rata basis as the promissory note is paid.

16.      EXCHANGE AND BUYOUT OF AWARDS.

         The Board may, at any time or from time to time, authorize the Company,
with the consent of the respective Participants, to issue new Awards in exchange
for the surrender and cancellation of any or all outstanding Awards. The Board
may at any time buy from a Participant an Award previously granted with payment
in cash, Shares (including Restricted Stock) or other consideration, based on
such terms and conditions as the Board and the Participant may agree.

17.      SECURITIES LAW AND OTHER REGULATORY COMPLIANCE.

         An Award will not be effective unless such Award is in compliance with
all applicable federal and state securities laws, rules and regulations of any
governmental body, and the requirements of any stock exchange or automated
quotation system upon which the Shares may then be listed or quoted, as they are
in effect on the date of grant of the Award and also on the date of exercise or
other issuance. Notwithstanding any other provision in this Plan, the Company
will have no obligation to issue or deliver certificates for Shares under this
Plan prior to: (a) obtaining any approvals from governmental agencies that the
Company determines are necessary or advisable; and/or (b) completion of any
registration or other qualification of such Shares under any state or federal
law or ruling of any governmental body that the Company determines to be
necessary or advisable. The Company will 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
automated quotation system, and the Company will have no liability for any
inability or failure to do so.

<PAGE>

18.      NO OBLIGATION TO EMPLOY.

         Nothing in this Plan or any Award granted under this Plan will confer
or be deemed to confer on any Participant any right to continue in the employ
of, or to continue any other relationship with, the Company or any Parent or
Subsidiary of the Company or limit in any way the right of the Company or any
Parent or Subsidiary of the Company to terminate Participant's employment or
other relationship at any time, with or without cause.

19.      CORPORATE TRANSACTIONS.

         19.1 ASSUMPTION OR REPLACEMENT OF AWARDS BY SUCCESSOR. In the event of
(a) a dissolution or liquidation of the Company, (b) a merger or consolidation
in which the Company is not the surviving corporation (other than a merger or
consolidation with a wholly-owned subsidiary, a reincorporation of the Company
in a different jurisdiction, or other transaction in which there is no
substantial change in the stockholders of the Company or their relative stock
holdings and the Awards granted under this Plan are assumed, converted or
replaced by the successor corporation, which assumption will be binding on all
Participants), (c) a merger in which the Company is the surviving corporation
but after which the stockholders of the Company immediately prior to such merger
(other than any stockholder that merges, or which owns or controls another
corporation that merges, with the Company in such merger) cease to own their
shares or other equity interest in the Company, (d) the sale of substantially
all of the assets of the Company, or (e) the acquisition, sale, or transfer of
more than 50% of the outstanding shares of the Company by tender offer or
similar transaction, any or all outstanding Awards may be assumed, converted or
replaced by the successor corporation (if any), which assumption, conversion or
replacement will be binding on all Participants. In the alternative, the
successor corporation may substitute equivalent Awards or provide substantially
similar consideration to Participants as was provided to stockholders (after
taking into account the existing provisions of the Awards). The successor
corporation may also issue, in place of outstanding Shares of the Company held
by the Participant, substantially similar shares or other property subject to
repurchase restrictions no less favorable to the Participant. In the event such
successor corporation (if any) refuses to assume or substitute Awards, as
provided above, pursuant to a transaction described in this Subsection 19.1,
such Awards will expire on such transaction at such time and on such conditions
as the Board will determine. Notwithstanding anything in this Plan to the
contrary, the Board may provide that the vesting of any or all Awards granted
pursuant to this Plan will accelerate upon a transaction described in this
Section 19. If the Board exercises such discretion with respect to Options, such
Options will become exercisable in full prior to the consummation of such event
at such time and on such conditions as the Board determines, and if such Options
are not exercised prior to the consummation of the corporate transaction, they
shall terminate at such time as determined by the Board.

         19.2 OTHER TREATMENT OF AWARDS. Subject to any greater rights granted
to Participants under the foregoing provisions of this Section 19, in the event
of the occurrence of any transaction described in Section 19.1, any outstanding
Awards will be treated as provided in the applicable agreement or plan of
merger, consolidation, dissolution, liquidation, or sale of assets.

         19.3 ASSUMPTION OF AWARDS BY THE COMPANY. The Company, from time to
time, also may substitute or assume outstanding awards granted by another
company, whether in connection with an acquisition of such other company or
otherwise, by either: (a) granting an Award under this Plan in substitution of
such other company's award; or (b) assuming such award as if it had been granted
under this Plan if the terms of such assumed award could be applied to an Award
granted under this Plan. Such substitution or assumption will be permissible if
the holder of the substituted or assumed award would have been eligible to be

<PAGE>

granted an Award under this Plan if the other company had applied the rules of
this Plan to such grant. In the event the Company assumes an award granted by
another company, the terms and conditions of such award will remain unchanged
(except that the exercise price and the number and nature of Shares issuable
upon exercise of any such option will be adjusted appropriately pursuant to
Section 424(a) of the Code). In the event the Company elects to grant a new
Option rather than assuming an existing option, such new Option may be granted
with a similarly adjusted Exercise Price.

20.      ADOPTION AND STOCKHOLDER APPROVAL.

         This Plan will become effective on the date on which it is adopted by
the Board (the "EFFECTIVE DATE"). This Plan shall be approved by the
stockholders of the Company within twelve (12) months before or after the date
this Plan is adopted by the Board. Upon the Effective Date, the Board may grant
Awards pursuant to this Plan. In the event that stockholder approval of this
Plan is not obtained within the time period provided herein, all Awards granted
hereunder shall be cancelled, any Shares issued pursuant to any Awards shall be
cancelled and any purchase of Shares issued hereunder shall be rescinded.

21.      TERM OF PLAN/GOVERNING LAW.

         Unless earlier terminated as provided herein, this Plan will terminate
ten (10) years from the date this Plan is adopted by the Board or, if earlier,
the date of stockholder approval. This Plan and all agreements thereunder shall
be governed by and construed in accordance with the laws of the State of
California.

22.      AMENDMENT OR TERMINATION OF PLAN.

         The Board may at any time terminate or amend this Plan in any respect,
including without limitation amendment of any form of Award Agreement or
instrument to be executed pursuant to this Plan; provided, however, that the
Board will not, without the approval of the stockholders of the Company, amend
this Plan in any manner that requires such stockholder approval.

23.      NONEXCLUSIVITY OF THE PLAN.

         Neither the adoption of this Plan by the Board, the submission of this
Plan to the stockholders of the Company for approval, nor any provision of this
Plan will be construed as creating any limitations on the power of the Board to
adopt such additional compensation arrangements as it may deem desirable,
including, without limitation, the granting of stock options and bonuses
otherwise than under this Plan, and such arrangements may be either generally
applicable or applicable only in specific cases.

24.      ACTION BY BOARD.

         Any action permitted or required to be taken by the Board or any
decision or determination permitted or required to be made by the Board pursuant
to this Plan shall be taken or made in the Board's sole and absolute discretion.
