      ISOs (as defined in Section 6 below) may be granted only to employees

employees, officers, directors, consultants, independent contractors and

such consultants, independent contractors and advisors render bona-fide services
not in connection with the offer and sale of securities in a capital-raising
transaction or promotion of the Company's securities. A person may be granted
more than one Award under this Plan.

      5. ADMINISTRATION.

<PAGE>

         5.1      Committee.

other actions under the Certificate of Incorporation and bylaws of the Company
generally.

      5.2 Committee Authority. Without limitation, the Committee will have the

<PAGE>

            (e) determine the number of Shares or other consideration subject to
Awards;

            (f) determine whether Awards will be granted singly, in combination

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 Committee 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. No member
of the Committee shall be personally liable for any action taken or decision
made in good faith relating to this Plan, and all members of the Committee shall
be fully protected and indemnified to the fullest extent permitted under
applicable law by the Company in respect to any such action, determination, or
interpretation.

      6. OPTIONS.

      The Committee 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 ("NQSOs"), 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:

<PAGE>

      6.1 Form of Option Grant. Each Option granted under this Plan will be
evidenced by an Award Agreement which 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 Committee 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 Committee makes the determination to grant such Option, unless
otherwise specified by the Committee. 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 Committee 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
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 Committee 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 Committee
determines, provided, however, that in all events a Participant will be entitled
to exercise an Option at the rate of at least 20% per year over five years from
the date of grant, subject to reasonable conditions such as continued
employment; and further provided that an Option granted to a Participant who is
an officer or director may become fully exercisable, subject to reasonable
conditions such as continued employment, at any time or during any period
established by the Company.

<PAGE>

      6.4 Exercise Price. The Exercise Price of an Option will be determined by
the Committee 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 Option
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 Committee, (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 the 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 longer
time period not exceeding five (5) years as may be determined by the Committee,
with any exercise beyond three (3) months after the Termination Date deemed to
be an NQSO).

<PAGE>

      (b) If the Participant's service is Terminated because of the
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 the Participant's Options may be exercised only to the extent
that such Options would have been exercisable by the Participant on the
Termination Date and must be exercised by the Participant (or the Participant's
legal representative) no later than twelve (12) months after the Termination
Date (or such longer time period not exceeding five (5) years as may be
determined by the Committee, 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).

      (c) Notwithstanding the provisions in paragraph 6.6(a) above, if the
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
Termination, whether or not after Termination the Participant may receive
payment from the Company or a 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 Committee 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 the 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.

<PAGE>

      6.9 Modification, Extension or Renewal. The Committee may modify, extend
or renew outstanding Options and authorize the grant of new Options in
substitution therefore, 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 Committee 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.

<PAGE>

      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 Committee 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, if any, 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 each
Participant) as the Committee will from time to time approve, and will comply
with and be subject to the terms and conditions of this Plan. The offer of a
Stock Award will be accepted by the Participant's execution and delivery of the
Stock Purchase Agreement (or similar agreement) and payment for the Shares to
the Company in accordance with the Stock Purchase Agreement.

      7.2 Purchase Price. The Purchase Price of Shares sold pursuant to a Stock
Award will be determined by the Committee on the date the Stock Award is granted
and may not be less than 85% of the Fair Market Value of the Shares on the grant
date, 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 may be subject to such
restrictions as the Committee 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 subject to restrictions, the Committee 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 transfer of any Stock Award, the Committee 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.

<PAGE>

      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 Committee determines
otherwise.

      8. STOCK BONUSES.

      8.1 Awards of Stock Bonuses. A Stock Bonus is an award of Shares 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 Committee 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 Committee 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 Committee may determine.

      8.2 Terms of Stock Bonuses. The Committee 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 Committee 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 Committee 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 Committee. The
Committee 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 Committee deems necessary or appropriate to reflect the
impact of extraordinary or unusual items, events or circumstances to avoid
windfalls or hardships.

<PAGE>

      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 Committee may determine.
Payment of an interest or dividend equivalent (if any) 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 Committee will determine.

      9. PAYMENT FOR SHARE PURCHASES.

      Payment for Shares purchased pursuant to this Plan may be made in cash (by
check) or, where expressly approved for the Participant by the Committee 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 the
Participant for more than six (6) months and have been paid for within the
meaning of SEC Rule 144; or (2) were obtained by the 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.

<PAGE>

      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 Committee 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
Committee and will be in writing in a form acceptable to the Committee.

      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 issued pursuant to a Stock Award with restrictions, 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 Stock Award; 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 13.

      11.2 Financial Statements. 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. NON-TRANSFERABILITY.

      Awards of Shares granted under this Plan, and any interest therein, will
not be transferable or assignable by the 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. Awards of Options granted under this Plan,
and any interest therein, will not be transferable or assignable by the
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, by
instrument to an inter vivos or testamentary trust in which the options are to
be passed to beneficiaries upon the death of the trustor, or by gift to
"immediate family" as that term is defined in 17 C.F.R. 240.16a-1(e). 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 Committee and set forth in the Award Agreement with respect to Awards that
are not ISOs.

      13. REPURCHASE RIGHTS.

      At the discretion of the Committee, the Company may reserve to itself
and/or its assignee(s) in the Award Agreement a right to repurchase a portion of
or all of the unvested Shares held by a Participant following such Participant's
Termination Date. 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 Purchase Price, as applicable.

      14. CERTIFICATES.

      All certificates for Shares or other securities delivered under this Plan
will be subject to such stop transfer orders, legends and other restrictions as
the Committee 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.

<PAGE>

      15. ESCROW; PLEDGE OF SHARES.

      To enforce any restrictions on a Participant's Shares, the Committee may
require the Participant to deposit all certificates representing Shares,
together with stock powers or other instruments of transfer approved by the
Committee 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 Committee may cause a legend or legends referencing such
restrictions to be placed on the certificates.

      16. EXCHANGE AND BUYOUT OF AWARDS.

      The Committee 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 Committee may at any time buy from a Participant an Award previously granted
with payment in cash, Shares or other consideration, based on such terms and
conditions as the Committee 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, (i)
the vesting of any or all Awards granted pursuant to this Plan will accelerate
upon a transaction described in this Section 19 and (ii) any or all Options
granted pursuant to this Plan will become exercisable in full prior to the
consummation of such event at such time and on such conditions as the Committee
determines. If such Options are not exercised prior to the consummation of the
corporate transaction, they shall terminate at such time as determined by the
Committee.

<PAGE>

      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
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"). Upon the Effective Date, the Committee may grant
Awards pursuant to this Plan. The Company intends to seek stockholder approval
of the Plan within twelve (12) months after the date this Plan is adopted by the
Board; provided, however, if the Company fails to obtain stockholder approval of
the Plan during such 12-month period, pursuant to Section 422 of the Code, any
Option granted as an ISO at any time under the Plan will not qualify as an ISO
within the meaning of the Code and will be deemed to be an NQSO.

      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.

<PAGE>

      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 COMMITTEE.

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