As amended through December 17, 2002 and adjusted for stock splits in April and
October 2000

           MILLENNIUM PHARMACEUTICALS, INC. 2000 STOCK INCENTIVE PLAN

1.  PURPOSE

        The purpose of this 2000 Stock Incentive Plan (the "Plan") of Millennium
Pharmaceuticals, Inc., a Delaware corporation (the "Company"), is to advance the
interests of the Company's stockholders by enhancing the Company's ability to
attract, retain and motivate persons who make (or are expected to make)
important contributions to the Company by providing such persons with equity
ownership opportunities and performance-based incentives and thereby better
aligning the interests of such persons with those of the Company's stockholders.
Except where the context otherwise requires, the term "Company" shall include
any of the Company's present or future subsidiary corporations as defined in
Section 424(f) of the Internal Revenue Code of 1986, as amended, and any
regulations promulgated thereunder (the "Code").

2.  ELIGIBILITY

        All of the Company's employees, officers, directors, consultants and
advisors (and any individuals who have accepted an offer for employment) are
eligible to be granted options, restricted stock awards, or other stock-based
awards (each, an "Award") under the Plan. Each person who has been granted an
Award under the Plan shall be deemed a "Participant."

3.  ADMINISTRATION, DELEGATION

        (a) ADMINISTRATION BY BOARD OF DIRECTORS. The Plan will be administered
by the Board of Directors of the Company (the "Board"). The Board shall have
authority to grant Awards and to adopt, amend and repeal such administrative
rules, guidelines and practices relating to the Plan as it shall deem advisable.
The Board may correct any defect, supply any omission or reconcile any
inconsistency in the Plan or any Award in the manner and to the extent it shall
deem expedient to carry the Plan into effect and it shall be the sole and final
judge of such expediency. All decisions by the Board shall be made in the
Board's sole discretion and shall be final and binding on all persons having or
claiming any interest in the Plan or in any Award. No director or person acting
pursuant to the authority delegated by the Board shall be liable for any action
or determination relating to or under the Plan made in good faith.

        (b) DELEGATION TO EXECUTIVE OFFICERS. To the extent permitted by
applicable law, the Board may delegate to one or more executive officers of the
Company the power to make Awards and exercise such other powers under the Plan
as the Board may determine, provided that the Board shall fix the maximum number
of shares subject to Awards and the maximum number of shares for any one
Participant to be made by such executive officers.

        (c) APPOINTMENT OF COMMITTEES. To the extent permitted by applicable
law, the Board may delegate any or all of its powers under the Plan to one or
more committees or subcommittees of the Board (a "Committee"). All references in
the Plan to the "Board" shall mean the Board or a Committee of the Board or the
executive officer referred to in Section 3(b) to the extent that the Board's
powers or authority under the Plan have been delegated to such Committee or
executive officer.

4.  STOCK AVAILABLE FOR AWARDS

        (a) NUMBER OF SHARES. Subject to adjustment under Section 8, Awards may
be made under the Plan for (i) up to five percent (5%) of the number of shares
of the Company's common stock, $.001 par

<Page>

value per share ("Common Stock") which are issued and outstanding on April 12,
2000, the date of the Company's 2000 Annual Meeting of Stockholders, plus (ii)
an annual increase in the number of shares available for Awards on the first day
of each of January 1, 2001, 2002 and 2003 equal to the lesser of (A) 5% of the
number of shares of Common Stock outstanding on the last business day preceding
each of January 1, 2001, 2002 and 2003, respectively or (B) a lesser number of
shares determined by the Board of Directors. The aggregate number of shares
available for grants of incentive stock options under the Plan is the lesser of
40,000,000 shares or the total number of shares authorized under the Plan.

        If any Award expires or is terminated, surrendered or canceled without
having been fully exercised or is forfeited in whole or in part or results in
any Common Stock not being issued, the unused Common Stock covered by such Award
shall again be available for the grant of Awards under the Plan, subject,
however, in the case of Incentive Stock Options (as hereinafter defined), to any
limitation required under the Code. Shares issued under the Plan may consist in
whole or in part of authorized but unissued shares or treasury shares.

        (b) PER-PARTICIPANT LIMIT. Subject to adjustment under Section 8, the
maximum number of shares of Common Stock with respect to which an Award may be
granted to any Participant under the Plan shall be 2,000,000 per calendar year.
The per-Participant limit described in this Section 4(b) shall be construed and
applied consistently with Section 162(m) of the Code ("Section 162(m)").

5.  STOCK OPTIONS

        (a) GENERAL. The Board may grant options to purchase Common Stock (each,
an "Option") and determine the number of shares of Common Stock to be covered by
each Option, the exercise price of each Option and the conditions and
limitations applicable to the exercise of each Option, including conditions
relating to applicable federal or state securities laws, as it considers
necessary or advisable. An Option which is not intended to be an Incentive Stock
Option (as hereinafter defined) shall be designated a "Nonstatutory Stock
Option."

        (b) INCENTIVE STOCK OPTIONS. An Option that the Board intends to be an
"incentive stock option" as defined in Section 422 of the Code (an "Incentive
Stock Option") shall only be granted to employees of the Company and shall be
subject to and shall be construed consistently with the requirements of Section
422 of the Code. The Company shall have no liability to a Participant, or any
other party, if an Option (or any part thereof) which is intended to be an
Incentive Stock Option is not an Incentive Stock Option.

        (c) EXERCISE PRICE. The Board shall establish the exercise price at the
time each Option is granted and specify it in the applicable option agreement;
provided, however, that the exercise price shall be not less than 100% of the
fair market value of the Common Stock, as determined by the Board, at the time
the Option is granted.

        (d) DURATION OF OPTIONS. Each Option shall be exercisable at such times
and subject to such terms and conditions as the Board may specify in the
applicable option agreement; PROVIDED, HOWEVER, that no Option will be granted
for a term in excess of 10 years.

        (e) EXERCISE OF OPTION. Options may be exercised by delivery to the
Company of a written notice of exercise signed by the proper person or by any
other form of notice (including electronic notice) approved by the Board
together with payment in full as specified in Section 5(f) for the number of
shares for which the Option is exercised.

        (f) PAYMENT UPON EXERCISE. Common Stock purchased upon the exercise of
an Option granted under the Plan shall be paid for as follows:

                                        2
<Page>

            (1) in cash or by check, payable to the order of the Company;

            (2) except as the Board may, in its sole discretion, otherwise
        provide in an option agreement, by (i) delivery of an irrevocable and
        unconditional undertaking by a creditworthy broker to deliver promptly
        to the Company sufficient funds to pay the exercise price or (ii)
        delivery by the Participant to the Company of a copy of irrevocable and
        unconditional instructions to a creditworthy broker to deliver promptly
        to the Company cash or a check sufficient to pay the exercise price;

            (3) when the Common Stock is registered under the Securities
        Exchange Act of 1934 (the "Exchange Act"), by delivery of shares of
        Common Stock owned by the Participant valued at their fair market value
        as determined by (or in a manner approved by) the Board in good faith
        ("Fair Market Value"), provided (i) such method of payment is then
        permitted under applicable law and (ii) such Common Stock was owned by
        the Participant at least six months prior to such delivery;

            (4) to the extent permitted by the Board, in its sole discretion by
        (i) delivery of a promissory note of the Participant to the Company on
        terms determined by the Board, or (ii) payment of such other lawful
        consideration as the Board may determine; or

            (5) by any combination of the above permitted forms of payment.

        (g) SUBSTITUTE OPTIONS. In connection with a merger or consolidation of
an entity with the Company or the acquisition by the Company of property or
stock of an entity, the Board may grant Options in substitution for any options
or other stock or stock-based awards granted by such entity or an affiliate
thereof. Substitute Options may be granted on such terms as the Board deems
appropriate in the circumstances, notwithstanding any limitations on Options
contained in the other sections of this Section 5.

6.  RESTRICTED STOCK

        (a) GRANTS. The Board may grant Awards entitling recipients to acquire
shares of Common Stock, subject to the right of the Company to repurchase all or
part of such shares at their issue price or other stated or formula price (or to
require forfeiture of such shares if issued at no cost) from the recipient in
the event that conditions specified by the Board in the applicable Award are not
satisfied prior to the end of the applicable restriction period or periods
established by the Board for such Award (each, a "Restricted Stock Award");
PROVIDED THAT, Restricted Stock Awards and other Awards issued pursuant to
Section 7 below shall be made for no more than 5% of the maximum cumulative
number of shares reserved for issuance under the Plan.

        (b) TERMS AND CONDITIONS. The Board shall determine the terms and
conditions of any such Restricted Stock Award, including the conditions for
repurchase (or forfeiture) and the issue price, if any. Any stock certificates
issued in respect of a Restricted Stock Award shall be registered in the name of
the Participant and, unless otherwise determined by the Board, deposited by the
Participant, together with a stock power endorsed in blank, with the Company (or
its designee). At the expiration of the applicable restriction periods, the
Company (or such designee) shall deliver the certificates no longer subject to
such restrictions to the Participant or if the Participant has died, to the
beneficiary designated, in a manner determined by the Board, by a Participant to
receive amounts due or exercise rights of the Participant in the event of the
Participant's death (the "Designated Beneficiary"). In the absence of an
effective designation by a Participant, Designated Beneficiary shall mean the
Participant's estate.

                                        3

7.  OTHER STOCK-BASED AWARDS

        The Board shall have the right to grant other Awards based upon the
Common Stock having such terms and conditions as the Board may determine,
including the grant of shares based upon certain conditions, the grant of
securities convertible into Common Stock and the grant of stock appreciation
rights.

8.  ADJUSTMENTS FOR CHANGES IN COMMON STOCK AND CERTAIN OTHER EVENTS

        (a) CHANGES IN CAPITALIZATION. In the event of any stock split, reverse
stock split, stock dividend, recapitalization, combination of shares,
reclassification of shares, spin-off or other similar change in capitalization
or event, or any distribution to holders of Common Stock other than a normal
cash dividend, (i) the number and class of securities available under this Plan,
(ii) the per-Participant limit set forth in Section 4(b), (iii) the number and
class of securities and exercise price per share subject to each outstanding
Option, (iv) the repurchase price per share subject to each outstanding
Restricted Stock Award, and (v) the terms of each other outstanding Award shall
be appropriately adjusted by the Company (or substituted Awards may be made, if
applicable) to the extent the Board shall determine, in good faith, that such an
adjustment (or substitution) is necessary and appropriate. If this Section 8(a)
applies and Section 8(c) also applies to any event, Section 8(c) shall be
applicable to such event, and this Section 8(a) shall not be applicable.

        (b) LIQUIDATION OR DISSOLUTION. In the event of a proposed liquidation
or dissolution of the Company, the Board shall upon written notice to the
Participants provide that all then unexercised Options will (i) become
exercisable in full as of a specified time at least 10 business days prior to
the effective date of such liquidation or dissolution and (ii) terminate
effective upon such liquidation or dissolution, except to the extent exercised
before such effective date. The Board may specify the effect of a liquidation or
dissolution on any Restricted Stock Award or other Award granted under the Plan
at the time of the grant of such Award.

        (c) ACQUISITION EVENTS

            (1) Definition. An "Acquisition Event" shall mean: (a) any merger or
        consolidation of the Company with or into another entity as a result of
        which the Common Stock is converted into or exchanged for the right to
        receive cash, securities or other property or (b) any exchange of shares
        of the Company for cash, securities or other property pursuant to a
        statutory share exchange transaction.

            (2) Consequences of an Acquisition Event on Options. Upon the
        occurrence of an Acquisition Event, or the execution by the Company of
        any agreement with respect to an Acquisition Event, the Board shall
        provide that all outstanding Options shall be assumed, or equivalent
        options shall be substituted, by the acquiring or succeeding corporation
        (or an affiliate thereof). For purposes hereof, an Option shall be
        considered to be assumed if, following consummation of the Acquisition
        Event, the Option confers the right to purchase, for each share of
        Common Stock subject to the Option immediately prior to the consummation
        of the Acquisition Event, the consideration (whether cash, securities or
        other property) received as a result of the Acquisition Event by holders
        of Common Stock for each share of Common Stock held immediately prior to
        the consummation of the Acquisition Event (and if holders were offered a
        choice of consideration, the type of consideration chosen by the holders
        of a majority of the outstanding shares of Common Stock); provided,
        however, that if the consideration received as a result of the
        Acquisition Event is not solely common stock of the acquiring or
        succeeding

                                        4
<Page>

        corporation (or an affiliate thereof), the Company may, with the consent
        of the acquiring or succeeding corporation, provide for the
        consideration to be received upon the exercise of Options to consist
        solely of common stock of the acquiring or succeeding corporation (or an
        affiliate thereof) equivalent in fair market value to the per share
        consideration received by holders of outstanding shares of Common Stock
        as a result of the Acquisition Event.

        Notwithstanding the foregoing, if the acquiring or succeeding
        corporation (or an affiliate thereof) does not agree to assume, or
        substitute for, such Options, then the Board shall, upon written notice
        to the Participants, provide that all then unexercised Options will
        become exercisable in full as of a specified time prior to the
        Acquisition Event and will terminate immediately prior to the
        consummation of such Acquisition Event, except to the extent exercised
        by the Participants before the consummation of such Acquisition Event;
        provided, however, that in the event of an Acquisition Event under the
        terms of which holders of Common Stock will receive upon consummation
        thereof a cash payment for each share of Common Stock surrendered
        pursuant to such Acquisition Event (the "Acquisition Price"), then the
        Board may instead provide that all outstanding Options shall terminate
        upon consummation of such Acquisition Event and that each Participant
        shall receive, in exchange therefor, a cash payment equal to the amount
        (if any) by which (A) the Acquisition Price multiplied by the number of
        shares of Common Stock subject to such outstanding Options (whether or
        not then exercisable), exceeds (B) the aggregate exercise price of such
        Options.

            (3) Consequences of an Acquisition Event on Restricted Stock Awards.
        Upon the occurrence of an Acquisition Event, the repurchase and other
        rights of the Company under each outstanding Restricted Stock Award
        shall inure to the benefit of the Company's successor and shall apply to
        the cash, securities or other property which the Common Stock was
        converted into or exchanged for pursuant to such Acquisition Event in
        the same manner and to the same extent as they applied to the Common
        Stock subject to such Restricted Stock Award.

            (4) Consequences of an Acquisition Event on Other Awards. The Board
        shall specify the effect of an Acquisition Event on any other Award
        granted under the Plan at the time of the grant of such Award.

        (d) CHANGE OF CONTROL.

        (1) Definition. A "Change of Control" occurs:

        (a) when a person, entity or group (within the meaning of Section
13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934) acquires beneficial
ownership of the Company's capital stock equal to 50% or more of either (i) the
then-outstanding shares of the Company's common stock or (ii) the combined
voting power of the Company's then-outstanding securities to vote generally in
the election of directors;

        (b) upon the consummation by the Company of (i) a reorganization, merger
or consolidation, provided that, in each case, the persons who were the
Company's stockholders immediately prior to the reorganization, merger or
consolidation do not, immediately after, own more than 50% of the combined
voting power entitled to vote generally in the election of directors of the
reorganized, merged or consolidated company's then outstanding voting
securities, or (ii) a liquidation or dissolution of the Company or the sale of
all or substantially all of the Company's assets; or

        (c) when the Continuing Directors (as defined below) do not constitute a
majority of the Board of Directors (or, if applicable, the Board of Directors of
a successor corporation to the Company), where the

                                        5
<Page>

term "Continuing Director" means at any date a member of the Board of Directors
(x) who was a member of the Board of Directors on the date of the initial
adoption of this provision by the Board of Directors or (y) who was nominated or
elected subsequent to such date by at least a majority of the directors who were
Continuing Directors at the time of such nomination or election or whose
election to the Board of Directors was recommended or endorsed by at least a
majority of the directors who were Continuing Directors at the time of such
nomination or election. But, any individual whose initial assumption of office
occurred as a result of an actual or threatened election contest with respect to
the election or removal of directors or other actual or threatened solicitation
of proxies or consents, by or on behalf of a person other than the Board of
Directors, is excluded from clause (c)(y) above.

        (2) Termination. Notwithstanding any provision to the contrary in this
Plan, if a Participant voluntarily terminates his or her employment with the
Company for Good Reason or if the Company terminates the Participant's
employment without Cause during the period one month before through twelve
months after the date of a Change in Control, then, on the Participant's
termination date:

        (a) all of the Participant's outstanding Awards will immediately vest in
full and will remain exercisable until the earlier of (i) the first anniversary
of the Participant's termination of employment or (ii) the end of the term of
the Award; and

        (b) any reacquisition or repurchase rights held by the Company with
respect to any of the Participant's Awards will lapse.

        (3) For purposes of this Section 8(d) only:

        (a) CAUSE means (i) the Participant's willful and continued failure to
substantially perform the Participant's material responsibilities to the Company
(except if the failure results from the Participant's incapacity caused by
physical or mental illness or disability); (ii) the Participant's conviction of
a felony involving moral turpitude; or (iii) the Participant's willful conduct
which materially injures the business of the Company, monetarily or otherwise.
If a Participant acts, or fails to act, in good faith and with the reasonable
belief that his or her act, or failure to act, was in the best interests of the
Company, then the act, or failure to act, will not be deemed willful for
purposes of this definition.

        (b) COMPANY includes any successor entity.

        (c) GOOD REASON means the occurrence, without the Participant's express
written consent, of:

        (i) a reduction in the Participant's title, annual base salary or a
significant reduction in responsibilities as in effect immediately prior to, or
as increased after, the effective date of the Change of Control; or

        (ii) the relocation of the Participant's principal place of employment
to a location more than fifty miles from the Participant's principal place of
employment prior to the effective date of the Change of Control or a relocation
that increases the Participant's commuting distance to and from the relocated
place of employment to more than fifty miles.

        (4) If the benefits to the Participant resulting from Section 8(d)(2)(a)
and 8(d)(2)(b) and any other benefits otherwise payable to a Participant
constitute a parachute payment ("Payment") within the meaning of Section 280G
(as amended or replaced) of the Code, and, except for this Section 8(d)(4),
would be subject to the excise tax imposed by Section 4999 (as amended or
replaced) of the Code (the "Excise Tax"), then the Payment will be the full
amount or a lesser amount (with cash payments reduced before Award
compensation), whichever results in the Participant's receipt, on an after tax
basis, of the

                                        6
<Page>

greater amount of the Payment whether or not all or some portion of the Payment
may be subject to the Excise Tax.

        Accountants selected by the Company will make, in writing and in good
faith, any determination required under this Section 8(d)(4) unless the Company
and the Participant otherwise agree in writing. The accountants may make
reasonable assumptions and approximations in applying the Code to make their
determination. The Company and the Participants will furnish to the accountants
any information and documents that the accountants may reasonably request. The
Company will pay all reasonable costs the accountants may incur in providing
this determination.

9.  GENERAL PROVISIONS APPLICABLE TO AWARDS

        (a) TRANSFERABILITY OF AWARDS. Except as the Board may otherwise
determine or provide in an Award, Awards shall not be sold, assigned,
transferred, pledged or otherwise encumbered by the person to whom they are
granted, either voluntarily or by operation of law, except by will or the laws
of descent and distribution, and, during the life of the Participant, shall be
exercisable only by the Participant. References to a Participant, to the extent
relevant in the context, shall include references to authorized transferees.

        (b) DOCUMENTATION. Each Award shall be evidenced by a written instrument
in such form as the Board shall determine. Each Award may contain terms and
conditions in addition to those set forth in the Plan.

        (c) BOARD DISCRETION. Except as otherwise provided by the Plan, each
Award may be made alone or in addition or in relation to any other Award. The
terms of each Award need not be identical, and the Board need not treat
Participants uniformly.

        (d) TERMINATION OF STATUS. The Board shall determine the effect on an
Award of the disability, death, retirement, authorized leave of absence or other
change in the employment or other status of a Participant and the extent to
which, and the period during which, the Participant, the Participant's legal
representative, conservator, guardian or Designated Beneficiary may exercise
rights under the Award.

        (e) WITHHOLDING. Each Participant shall pay to the Company, or make
provision satisfactory to the Board for payment of, any taxes required by law to
be withheld in connection with Awards to such Participant no later than the date
of the event creating the tax liability. Except as the Board may otherwise
provide in an Award, when the Common Stock is registered under the Exchange Act,
Participants may, to the extent then permitted under applicable law, satisfy
such tax obligations in whole or in part by delivery of shares of Common Stock,
including shares retained from the Award creating the tax obligation, valued at
their Fair Market Value. The Company may, to the extent permitted by law, deduct
any such tax obligations from any payment of any kind otherwise due to a
Participant.

        (f) AMENDMENT OF AWARD; PROHIBITION ON REPRICING. The Board may amend,
modify or terminate any outstanding Award, including but not limited to,
substituting therefor another Award of the same or a different type, changing
the date of exercise or realization, and converting an Incentive Stock Option to
a Nonstatutory Stock Option, PROVIDED THAT the Participant's consent to such
action shall be required unless the Board determines that the action, taking
into account any related action, would not materially and adversely affect the
Participant, and FURTHER PROVIDED, that the Board may not amend, modify,
substitute or otherwise change any outstanding Award in order to effect a
decrease in the exercise price thereof.

        (g) CONDITIONS ON DELIVERY OF STOCK. The Company will not be obligated
to deliver any shares of Common Stock pursuant to the Plan or to remove
restrictions from shares previously delivered under the

                                        7
<Page>

Plan until (i) all conditions of the Award have been met or removed to the
satisfaction of the Company, (ii) in the opinion of the Company's counsel, all
other legal matters in connection with the issuance and delivery of such shares
have been satisfied, including any applicable securities laws and any applicable
stock exchange or stock market rules and regulations, and (iii) the Participant
has executed and delivered to the Company such representations or agreements as
the Company may consider appropriate to satisfy the requirements of any
applicable laws, rules or regulations.

        (h) ACCELERATION. The Board may at any time provide that any Options
shall become immediately exercisable in full or in part, that any Restricted
Stock Awards shall be free of restrictions in full or in part or that any other
Awards may become exercisable in full or in part or free of some or all
restrictions or conditions, or otherwise realizable in full or in part, as the
case may be.

10. MISCELLANEOUS

        (a) NO RIGHT TO EMPLOYMENT OR OTHER STATUS. No person shall have any
claim or right to be granted an Award, and the grant of an Award shall not be
construed as giving a Participant the right to continued employment or any other
relationship with the Company. The Company expressly reserves the right at any
time to dismiss or otherwise terminate its relationship with a Participant free
from any liability or claim under the Plan, except as expressly provided in the
applicable Award.

        (b) NO RIGHTS AS STOCKHOLDER. Subject to the provisions of the
applicable Award, no Participant or Designated Beneficiary shall have any rights
as a stockholder with respect to any shares of Common Stock to be distributed
with respect to an Award until becoming the record holder of such shares.
Notwithstanding the foregoing, in the event the Company effects a split of the
Common Stock by means of a stock dividend and the exercise price of and the
number of shares subject to such Option are adjusted as of the date of the
distribution of the dividend (rather than as of the record date for such
dividend), then an optionee who exercises an Option between the record date and
the distribution date for such stock dividend shall be entitled to receive, on
the distribution date, the stock dividend with respect to the shares of Common
Stock acquired upon such Option exercise, notwithstanding the fact that such
shares were not outstanding as of the close of business on the record date for
such stock dividend.

        (c) EFFECTIVE DATE AND TERM OF PLAN. The Plan shall become effective on
the date on which it is adopted by the Board, but no Award granted to a
Participant that is intended to comply with Section 162(m) shall become
exercisable, vested or realizable, as applicable to such Award, unless and until
the Plan has been approved by the Company's stockholders to the extent
stockholder approval is required by Section 162(m) in the manner required under
Section 162(m) (including the vote required under Section 162(m)). No Awards
shall be granted under the Plan after the completion of ten years from the
earlier of (i) the date on which the Plan was adopted by the Board or (ii) the
date the Plan was approved by the Company's stockholders, but Awards previously
granted may extend beyond that date.

        (d) AMENDMENT OF PLAN. The Board may amend, suspend or terminate the
Plan or any portion thereof at any time, provided that to the extent required by
Section 162(m), no Award granted to a Participant that is intended to comply
with Section 162(m) after the date of such amendment shall become exercisable,

As amended through December 17, 2002 and adjusted for stock splits in April and

                        MILLENNIUM PHARMACEUTICALS, INC.

                           1997 EQUITY INCENTIVE PLAN

1.   PURPOSE.

     The purpose of this plan (the "Plan") is to secure for Millennium
Pharmaceuticals, Inc. (the "Company") and its shareholders the benefits arising
from capital stock ownership by employees (excluding executive officers and
employees who serve as directors) of, and consultants or advisors to, the
Company and its parent and subsidiary corporations who are expected to
contribute to the Company's future growth and success. Except where the context
otherwise requires, the term "Company" shall include the parent and all present
and future subsidiaries of the Company as defined in Sections 424(e) and 424(f)
of the Internal Revenue Code of 1986, as amended or replaced from time to time
(the "Code").

2.   TYPES OF OPTIONS AND AWARDS; ADMINISTRATION.

     (a) TYPES OF OPTIONS AND AWARDS. Options granted pursuant to the Plan shall
be authorized by action of the Board of Directors of the Company (or a Committee
designated by the Board of Directors) and may be either incentive stock options
("Incentive Stock Options") meeting the requirements of Section 422 of the Code
or non-statutory options which are not intended to meet the requirements of
Section 422 of the Code. Awards granted pursuant to the Plan shall be authorized
by action of the Board of Directors of the Company (or a Committee designated by
the Board of Directors) and shall meet the requirements of Section 13 of the
Plan.

     (b) ADMINISTRATION. The Plan will be administered by the Board of Directors
of the Company, whose construction and interpretation of the terms and
provisions of the Plan shall be final and conclusive. The Board of Directors may
in its sole discretion (i) grant options to purchase shares of the Company's
Common Stock (as defined in Section 4 of the Plan), and issue shares upon
exercise of such options as provided in the Plan and (ii) make awards for the
purchase of shares of Common Stock pursuant to Section 13 of the Plan. The Board
shall have authority, subject to the express provisions of the Plan, to construe
the respective option agreements, awards and the Plan, to prescribe, amend and
rescind rules and regulations relating to the Plan, to determine the terms and
provisions of the respective option agreements and awards, which need not be
identical, and to make all other determinations in the judgment of the Board of
Directors necessary or desirable for the administration of the Plan. The Board
of Directors may correct any defect or supply any omission or reconcile any
inconsistency in the Plan or in any option agreement or award in the manner and
to the extent it shall deem expedient to carry the Plan into effect and it shall
be the sole and final judge of such expediency. No director or person acting
pursuant to authority delegated by the Board of Directors shall be liable for
any action or determination made in good faith. The Board of Directors may, to
the full

<Page>

extent permitted by or consistent with applicable laws or regulations
(including, without limitation, applicable state law), delegate any or all of
its powers under the Plan to a committee (the "Committee") appointed by the
Board of Directors, and if the Committee is so appointed all references to the
Board of Directors in the Plan shall mean and relate to such Committee to the
extent authority is so delegated to such Committee.

3.   ELIGIBILITY. Options and awards may be granted or made to persons who are,
at the time of grant, employees (excluding executive officers and employees who
serve as directors) of, or consultants or advisors to, the Company; PROVIDED,
that the class of individuals to whom Incentive Stock Options may be granted
shall be limited to all employees (excluding executive officers and employees
who serve as directors) of the Company. A person who has been granted an option
or award may, if he or she is otherwise eligible, be granted additional options
or awards if the Board of Directors shall so determine. Subject to adjustment as
provided in Section 16 below, the maximum number of shares with respect to which
options or restricted stock awards may be granted to any person under the Plan
shall not exceed 1,200,000 shares of Common Stock during any calendar year
during the term of the Plan. For the purpose of calculating such maximum number,
(a) an option or award shall continue to be treated as outstanding
notwithstanding its repricing, cancellation or expiration and (b) the repricing
of an outstanding option or award or the issuance of a new option or award in
substitution for a cancelled option or award shall be deemed to constitute the
grant of a new additional option or award, as the case may be, separate from the
original grant that is repriced or cancelled.

4.   STOCK SUBJECT TO PLAN.

     Subject to adjustment as provided in Section 16 below, the total number of
shares which may be issued and sold under the Plan is 16,000,000 shares of
Common Stock, $.001 par value per share ("Common Stock"). If an option granted
under the Plan shall expire or terminate for any reason without having been
exercised in full, the unpurchased shares subject to such option shall again be
available for subsequent option grants or awards under the Plan.

5.   FORMS OF OPTION AGREEMENTS.

     As a condition to the grant of an option under the Plan, each recipient of
an option shall execute an option agreement in such form not inconsistent with
the Plan as may be approved by the Board of Directors. Such option agreements
may differ among recipients.

6.   PURCHASE PRICE UPON EXERCISE OF OPTIONS.

     (a) GENERAL. The purchase price per share of Common Stock deliverable upon
the exercise of an option shall be determined by the Board of Directors,
PROVIDED, HOWEVER, that in the case of an Incentive Stock Option, the exercise
price shall not be less than 100% of the fair market value of such stock, as
determined by the Board of

                                       -2-
<Page>

Directors, at the time of grant of such option, or less than 110% of such fair
market value in the case of options described in Section 11(b).

     (b) PAYMENT OF PURCHASE PRICE. Options granted under the Plan may provide
for the payment of the exercise price by delivery of cash or a check to the
order of the Company in an amount equal to the exercise price of such options,
or, to the extent provided in the applicable option agreement, (i) by delivery
to the Company of shares of Common Stock of the Company already owned by the
optionee having a fair market value equal in amount to the exercise price of the
options being exercised, (ii) by any other means (including without limitation
by delivery of a promissory note of the optionee payable on such terms as are
specified by the Board of Directors) which the Board of Directors determines are
consistent with the purpose of the Plan and with applicable laws and regulations
(including, without limitation, the provisions of Regulation T promulgated by
the Federal Reserve Board) or (iii) by any combination of such methods of
payment. The fair market value of any shares of the Company's Common Stock or
other non-cash consideration which may be delivered upon exercise of an option
shall be determined in such manner as may be prescribed by the Board of
Directors.

7.   OPTION PERIOD.

     Each option and all rights thereunder shall expire on such date as shall be
set forth in the applicable option agreement, except that such date, in the case
of an Incentive Stock Option, shall in no case be later than ten years after the
date on which the option is granted.

8.   EXERCISE OF OPTIONS.

     Each option granted under the Plan shall be exercisable either in full or
in installments at such time or times and during such period as shall be set
forth in the agreement evidencing such option, subject to the provisions of the
Plan.

9.   NONTRANSFERABILITY OF OPTIONS.

     Incentive Stock Options shall not be assignable or transferable by the
person to whom it is granted, either voluntarily or by operation of law, except
by will or the laws of descent and distribution, and, during the life of the
optionee, shall be exercisable only by the optionee.

10.  EFFECT OF TERMINATION OF EMPLOYMENT OR OTHER RELATIONSHIP.

     The Board of Directors shall determine the period of time during which an
optionee may exercise an option following (i) the termination of the optionee's
employment or other relationship with the Company or (ii) the death or
disability of the optionee. Such periods shall be set forth in the agreement
evidencing such option.

                                       -3-
<Page>

11.  INCENTIVE STOCK OPTIONS.

     Options granted under the Plan which are intended to be Incentive Stock
Options shall be subject to the following additional terms and conditions:

     (a) EXPRESS DESIGNATION. All Incentive Stock Options granted under the Plan
shall, at the time of grant, be specifically designated as such in the option
agreement covering such Incentive Stock Options.

     (b) 10% SHAREHOLDER. If any employee to whom an Incentive Stock Option is
to be granted under the Plan is, at the time of the grant of such option, the
owner of stock possessing more than 10% of the total combined voting power of
all classes of stock of the Company (after taking into account the attribution
of stock ownership rules of Section 424(d) of the Code), then the following
special provisions shall be applicable to the Incentive Stock Option granted to
such individual:

         (i)   The purchase price per share of the Common Stock subject to such
Incentive Stock Option shall not be less than 110% of the fair market value of
one share of Common Stock at the time of grant; and

         (ii)  The option exercise period shall not exceed five years from the
date of grant.

     (c) DOLLAR LIMITATION. For so long as the Code shall so provide, options
granted to any employee under the Plan (and any other incentive stock option
plans of the Company) which are intended to constitute Incentive Stock Options
shall not constitute Incentive Stock Options to the extent that such options, in
the aggregate, become exercisable for the first time in any one calendar year
for shares of Common Stock with an aggregate fair market value (determined as of
the respective date or dates of grant) of more than $100,000.

     (d) TERMINATION OF EMPLOYMENT DEATH OR DISABILITY. No Incentive Stock
Option may be exercised unless, at the time of such exercise, the optionee is,
and has been continuously since the date of grant of his or her option, employed
by the Company, except that:

         (i)   an Incentive Stock Option may be exercised within the period of
three months after the date the optionee ceases to be an employee of the Company
(or within such lesser period as may be specified in the applicable option
agreement), PROVIDED, that the agreement with respect to such option may
designate a longer exercise period and that the exercise after such three-month
period shall be treated as the exercise of a non-statutory option under the
Plan;

         (ii)  if the optionee dies while in the employ of the Company, or
within three months after the optionee ceases to be such an employee, the
Incentive Stock Option may be exercised, by the person to whom it is transferred
by will or the laws of

                                       -4-
<Page>

descent and distribution, within the period of one year after the date of death
(or within such lesser period as may be specified in the applicable option
agreement); and

         (iii) if the optionee becomes disabled (within the meaning of Section
22(e)(3) of the Code or any successor provision thereto) while in the employ of
the Company, the Incentive Stock Option may be exercised within the period of
one year after the date the optionee ceases to be such an employee because of
such disability (or within such lesser period as may be specified in the
applicable option agreement).

For all purposes of the Plan and any option or award granted hereunder,
"employment" shall be defined in accordance with the provisions of
Section 1.421-7(h) of the Income Tax Regulations (or any successor regulations).
Notwithstanding the foregoing provisions, no stock option may be exercised after
its expiration date.

12.  ADDITIONAL PROVISIONS.

     (a) ADDITIONAL OPTION PROVISIONS. The Board of Directors may, in its sole
discretion, include additional provisions in any option granted under the Plan,
including without limitation restrictions on transfer, repurchase rights,
commitments to pay cash bonuses, to make, arrange for or guaranty loans or to
transfer other property to optionees upon exercise of options, or such other
provisions as shall be determined by the Board of Directors; PROVIDED THAT such
additional provisions shall not be inconsistent with any other term or condition
of the Plan.

     (b) ACCELERATION, EXTENSION, ETC. The Board of Directors may, in its sole
discretion, (i) accelerate the date or dates on which all or any particular
option or options granted under the Plan may be exercised or (ii) extend the
dates during which all or any particular option or options granted under the
Plan may be exercised; provided, however, that no such extension shall be
permitted if it would cause the Plan to fail to comply with Section 422 of the
Code.

13.  AWARDS.

     A restricted stock award (an "award") shall consist of the sale and
issuance by the Company of shares of Common Stock, and the purchase by the
recipient of such shares, subject to the terms, conditions and restrictions
described in the document evidencing the award and in this Section 13 and
elsewhere in the Plan.

     (a) EXECUTION OF RESTRICTED STOCK AWARD AGREEMENT. As a condition to an
award under the Plan, each recipient of an award shall execute an agreement in
such form, which may differ among recipients, as shall be specified by the Board
of Directors at the time of such award.

     (b) PRICE. The Board of Directors shall determine the price at which shares
of Common Stock shall be sold to recipients of awards under the Plan. The Board
of Directors may, in its discretion, issue shares pursuant to awards without the
payment of

                                       -5-
<Page>

any cash purchase price by the recipients or issue shares pursuant to awards at
a purchase price below the then fair market value of the Common Stock. If a
purchase price is required to be paid, it shall be paid in cash or by check
payable to the order of the Company at the time that the award is accepted by
the recipient, or by such other means as may be approved by the Board of
Directors.

     (c) NUMBER OF SHARES. The award shall specify the number of shares of
Common Stock granted thereunder.

     (d) RESTRICTIONS ON TRANSFER. In addition to such other terms, conditions
and restrictions upon awards as shall be imposed by the Board of Directors, all
shares issued pursuant to an award shall be subject to the following
restrictions:

         (1)   All shares of Common Stock subject to an award (including any
shares issued pursuant to paragraph (e) of this Section) shall be subject to
certain restrictions on disposition and obligations of resale to the Company as
provided in subparagraph (2) below for the period specified in the document
evidencing the award, and shall not be sold, assigned, transferred, pledged,
hypothecated or otherwise disposed of until such restrictions lapse. The period
during which such restrictions are applicable is referred to as the "Restricted
Period."

         (2)   In the event that a recipient's employment with the Company (or
consultancy or advisory relationship, as the case may be) is terminated within
the Restricted Period, whether such termination is voluntary or involuntary,
with or without cause, or because of the death or disability of the recipient,
the Company shall have the right and option for a period of three months
following such termination to buy for cash that number of the shares of Common
Stock purchased under the award as to which the restrictions on transfer and the
forfeiture provisions contained in the award have not then lapsed, at a price
equal to the price per share originally paid by the recipient. If such
termination occurs within the last three months of the applicable restrictions,
the restrictions and repurchase rights of the Company shall continue to apply
until the expiration of the Company's three month option period.

         (3)   Notwithstanding subparagraphs (1) and (2) above, the Board of
Directors may, in its discretion, either at the time that an award is made or at
any time thereafter, waive its right to repurchase shares of Common Stock upon
the occurrence of any of the events described in this paragraph (d) or remove or
modify any part or all of the restrictions. In addition, the Board of Directors
may, in its discretion, impose upon the recipient of an award at the time of
such award such other restrictions on any shares of Common Stock issued pursuant
to such award as the Board of Directors may deem advisable.

     (e) ADDITIONAL SHARES. Any shares received by a recipient of an award as a
stock dividend on, or as a result of stock splits, combinations, exchanges of
shares, reorganizations, mergers, consolidations or otherwise with respect to,
shares of Common Stock received pursuant to such award shall have the same
status and shall bear the same

                                       -6-
<Page>

restrictions, all on a proportionate basis, as the shares initially purchased
pursuant to such award.

     (f) TRANSFERS IN BREACH OF AWARD. If any transfer of shares purchased
pursuant to an award is made or attempted contrary to the terms of the Plan and
of such award, the Board of Directors shall have the right to purchase for the
account of the Company those shares from the owner thereof or his or her
transferee at any time before or after the transfer at the price paid for such
shares by the person to whom they were awarded under the Plan. In addition to
any other legal or equitable remedies which it may have, the Company may enforce
its rights by specific performance to the extent permitted by law. The Company
may refuse for any purpose to recognize as a shareholder of the Company any
transferee who receives any shares contrary to the provisions of the Plan and
the applicable award or any recipient of an award who breaches his or her
obligation to resell shares as required by the provisions of the Plan and the
applicable award, and the Company may retain and/or recover all dividends on
such shares which were paid or payable subsequent to the date on which the
prohibited transfer or breach was made or attempted.

     (g) ADDITIONAL AWARD PROVISIONS. The Board of Directors may, in its sole
discretion, include additional provisions in any award granted under the Plan,
including without limitation commitments to pay cash bonuses, make, arrange for
or guarantee loans or transfer other property to recipients upon the grant of
awards, or such other provisions as shall be determined by the Board of
Directors.

14.  GENERAL RESTRICTIONS.

     (a) INVESTMENT REPRESENTATIONS. The Company may require any person to whom
an option or award is granted, as a condition of exercising such option or
purchasing the shares subject to the award, to give written assurances in
substance and form satisfactory to the Company to the effect that such person is
acquiring the Common Stock subject to the option or award for his or her own
account for investment and not with any present intention of selling or
otherwise distributing the same, and to such other effects as the Company deems
necessary or appropriate in order to comply with federal and applicable state
securities laws.

     (b) COMPLIANCE WITH SECURITIES LAWS. Each option and award shall be subject
to the requirement that if, at any time, counsel to the Company shall determine
that the listing, registration or qualification of the shares subject to such
option or award upon any securities exchange or under any state or federal law,
or the consent or approval of any governmental or regulatory body, or that the
disclosure of non-public information or the satisfaction of any other condition
is necessary as a condition of, or in connection with, the issuance or purchase
of shares thereunder, such option or award may not be exercised, in whole or in
part, unless such listing, registration, qualification, consent or approval, or
satisfaction of such condition shall have been effected or obtained on
conditions acceptable to the Board of Directors. Nothing herein shall be deemed
to

                                       -7-
<Page>

require the Company to apply for or to obtain such listing, registration or
qualification, or to satisfy such condition.

15.  RIGHTS AS A SHAREHOLDER.

     The holder of an option or recipient of an award shall have no rights as a
shareholder with respect to any shares covered by the option or award
(including, without limitation, any rights to receive dividends or non-cash
distributions with respect to such shares) until the date of issue of a stock
certificate to him or her for such shares. No adjustment shall be made for
dividends or other rights for which the record date is prior to the date such
stock certificate is issued.

16.  ADJUSTMENT PROVISIONS FOR RECAPITALIZATIONS AND RELATED TRANSACTIONS.

     (a) GENERAL. If, through or as a result of any merger, consolidation, sale
of all or substantially all of the assets of the Company, reorganization,
recapitalization, reclassification, stock dividend, stock split, reverse stock
split or other similar transaction, (i) the outstanding shares of Common Stock
are increased or decreased or are exchanged for a different number or kind of
shares or other securities of the Company, or (ii) additional shares or new or
different shares or other securities of the Company or other non-cash assets are
distributed with respect to such shares of Common Stock or other securities, an
appropriate and proportionate adjustment shall be made in (x) the maximum number
and kind of shares reserved for issuance under the Plan, (y) the number and kind
of shares or other securities subject to then outstanding options under the
Plan, and (z) the price for each share subject to any then outstanding options
under the Plan or repurchase rights of the Company, without changing the
aggregate purchase price as to which such options remain exercisable, provided
that no adjustment shall be made pursuant to this Section 16 if such adjustment
would cause the Plan to fail to comply with Section 422 of the Code.

     (b) BOARD AUTHORITY TO MAKE ADJUSTMENTS. Any adjustments under this Section
16 will be made by the Board of Directors, whose determination as to what
adjustments, if any, will be made and the extent thereof will be final, binding
and conclusive. No fractional shares will be issued under the Plan on account of
any such adjustments.

17.  MERGER CONSOLIDATION ASSET SALE, LIQUIDATION ETC.

     (a) GENERAL. In the event of a consolidation or merger m which outstanding
shares of Common Stock are exchanged for securities, cash or other property of
any other corporation or business entity or in the event of a liquidation of the
Company or sale of all or substantially all of the assets of the Company, the
Board of Directors of the Company, or the board of directors of any corporation
assuming the obligations of the Company, may, in its discretion, take any one or
more of the following actions, as to outstanding options and awards: (i) provide
that such options shall be assumed, or equivalent options shall be substituted,
by the acquiring or succeeding corporation (or an

                                       -8-
<Page>

affiliate thereof), PROVIDED that any such options substituted for Incentive
Stock Options shall meet the requirements of Section 424(a) of the Code, (ii)
upon written notice to the optionees, provide that all unexercised options will
terminate immediately prior to the consummation of such transaction unless
exercised by the optionee within a specified period following the date of such
notice, (iii) in the event of a merger under the terms of which holders of the
Common Stock of the Company will receive upon consummation thereof a cash
payment for each share surrendered in the merger (the "Merger Price"), make or
provide for a cash payment to the optionees equal to the difference between (A)
the Merger Price times the number of shares of Common Stock subject to such
outstanding options (to the extent then exercisable at prices not in excess of
the Merger Price) and (B) the aggregate exercise price of all such outstanding
options in exchange for the termination of such options, and (iv) provide that
all or any outstanding options shall become exercisable in full, any
restrictions on exercising outstanding options issued pursuant to the Plan prior
to any given date shall terminate and any restrictions on and rights of the
Company to repurchase shares covered by outstanding awards issued pursuant to
the Plan shall terminate.

     (b) SUBSTITUTE OPTIONS. The Company may grant options under the Plan in
substitution for options held by employees of another corporation who become
employees of the Company, or a subsidiary of the Company, as the result of a
merger or consolidation of the employing corporation with the Company or a
subsidiary of the Company, or as a result of the acquisition by the Company, or
one of its subsidiaries, of property or stock of the employing corporation. The
Company may direct that substitute options be granted on such terms and
conditions as the Board of Directors considers appropriate in the circumstances.

17A. CHANGE OF CONTROL.

     (a) Change of Control occurs:

         (i)   when a person, entity or group (within the meaning of Section
13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934) acquires beneficial
ownership of the Company's capital stock equal to 50% or more of either (i) the
then-outstanding shares of the Company's common stock or (ii) the combined
voting power of the Company's then-outstanding securities to vote generally in
the election of directors;

         (ii)  upon the consummation by the Company of (i) a reorganization,
merger or consolidation, provided that, in each case, the persons who were the
Company's stockholders immediately prior to the reorganization, merger or
consolidation do not, immediately after, own more than 50% of the combined
voting power entitled to vote generally in the election of directors of the
reorganized, merged or consolidated company's then outstanding voting
securities, or (ii) a liquidation or dissolution of the Company or the sale of
all or substantially all of the Company's assets; or

         (iii) when the Continuing Directors (as defined below) do not
constitute a majority of the Board of Directors (or, if applicable, the Board of
Directors of a

                                       -9-
<Page>

successor corporation to the Company), where the term "Continuing Director"
means at any date a member of the Board of Directors (x) who was a member of the
Board of Directors on the date of the initial adoption of this provision by the
Board of Directors or (y) who was nominated or elected subsequent to such date
by at least a majority of the directors who were Continuing Directors at the
time of such nomination or election or whose election to the Board of Directors
was recommended or endorsed by at least a majority of the directors who were
Continuing Directors at the time of such nomination or election. But, any
individual whose initial assumption of office occurred as a result of an actual
or threatened election contest with respect to the election or removal of
directors or other actual or threatened solicitation of proxies or consents, by
or on behalf of a person other than the Board of Directors, is excluded from
clause (iii)(y) above.

     (b) Notwithstanding any provision to the contrary in this Plan, if an
optionee or a recipient of an award (a "Participant") voluntarily terminates his
or her employment with the Company for Good Reason or if the Company terminates
the Participant's employment without Cause during the period one month before
through twelve months after the date of a Change in Control, then, on the
Participant's termination date:

         (i)   all of the Participant's outstanding options and awards will
immediately vest in full and will remain exercisable until the earlier of (a)
the first anniversary of the Participant's termination of employment or (b) the
end of the term of the option or award; and

         (ii)  any reacquisition or repurchase rights held by the Company with
respect to any of the Participant's options and awards will lapse.

     (c) For purposes of this Section only:

         CAUSE means (1) the Participant's willful and continued failure to
substantially perform the Participant's material responsibilities to the Company
(except if the failure results from the Participant's incapacity caused by
physical or mental illness or disability); (2) the Participant's conviction of a
felony involving moral turpitude; or (3) the Participant's willful conduct which
materially injures the business of the Company, monetarily or otherwise. If a
Participant acts, or fails to act, in good faith and with the reasonable belief
that his or her act, or failure to act, was in the best interests of the
Company, then the act, or failure to act, will not be deemed willful for
purposes of this definition.

         COMPANY includes any successor entity.

         GOOD REASON means the occurrence, without the Participant's express
written consent, of:

         (1)   a reduction in the Participant's title, annual base salary or a
significant reduction in responsibilities as in effect immediately prior to, or
as increased after, the effective date of the Change of Control; or

                                      -10-
<Page>

         (2)   the relocation of the Participant's principal place of employment
to a location more than fifty miles from the Participant's principal place of
employment prior to the effective date of the Change of Control or a relocation
that increases the Participant's commuting distance to and from the relocated
place of employment to more than fifty miles.

     (d) If the benefits to the Participant resulting from Section 17A(b)(i) and
17A(b)(ii) and any other benefits otherwise payable to a Participant constitute
a parachute payment ("Payment") within the meaning of Section 280G (as amended
or replaced) of the Code, and, except for this Section 17A(d), would be subject
to the excise tax imposed by Section 4999 (as amended or replaced) of the Code
(the "Excise Tax"), then the Payment will be the full amount or a lesser amount
(with cash payments reduced before option and award compensation), whichever
results in the Participant's receipt, on an after tax basis, of the greater
amount of the Payment whether or not all or some portion of the Payment may be
subject to the Excise Tax.

     Accountants selected by the Company will make, in writing and in good
faith, any determination required under this Section 17A(d) unless the Company
and the Participant otherwise agree in writing. The accountants may make
reasonable assumptions and approximations in applying the Code to make their
determination. The Company and the Participants will furnish to the accountants
any information and documents that the accountants may reasonably request. The
Company will pay all reasonable costs the accountants may incur in providing
this determination.

18.  NO SPECIAL EMPLOYMENT RIGHTS.

     Nothing contained in the Plan or in any option or award shall confer upon
any recipient of an award or optionee any right with respect to the continuation
of his or her employment by the Company or interfere in any way with the right
of the Company at any time to terminate such employment or to increase or
decrease the compensation of the optionee.

19.  OTHER EMPLOYEE BENEFITS.

     Except as to plans which by their terms include such amounts as
compensation, neither the amount of any compensation deemed to be received by an
employee as a result of the exercise of an option or the sale of shares received
upon such exercise nor the value of an award granted to an employee will
constitute compensation with respect to which any other employee benefits of
such employee are determined, including, without limitation, benefits under any
bonus, pension, profit-sharing, life insurance or salary continuation plan,
except as otherwise specifically determined by the Board of Directors.

20.  AMENDMENT OF THE PLAN.

     (a) The Board of Directors may at any time, and from time to time, modify
or amend the Plan in any respect, except that if at any time the approval of the
shareholders of the Company is required as to such modification or amendment
under Section 422 of the Code or any successor provision with respect to
Incentive Stock Options, the Board of Directors may not effect such modification
or amendment without such approval.

     (b) The termination or any modification or amendment of the Plan shall not,
without the consent of an optionee or recipient of an award, affect his or her
rights under an option or award previously granted to him or her. With the
consent of the optionee or recipient of the award affected, the Board of
Directors may amend outstanding option agreements or awards in a manner not
inconsistent with the Plan. The Board of Directors shall have the right to amend
or modify the terms and provisions of the Plan and of any outstanding Incentive
Stock Options granted under the Plan to the extent necessary to qualify any or
all such options for such favorable federal income tax treatment (including
deferral of taxation upon exercise) as may be afforded incentive stock options
under Section 422 of the Code.

21.  WITHHOLDING.

     (a) The Company shall have the right to deduct from payments of any kind
otherwise due to the optionee or recipient of an award any federal, state or
local taxes of any kind required by law to be withheld with respect to any
shares issued upon exercise of options under the Plan or the purchase of shares
subject to the award. Subject to the prior approval of the Company, which may be
withheld by the Company in its sole discretion, the optionee or recipient of an
award may elect to satisfy such obligations, in whole or in part, (i) by causing
the Company to withhold shares of Common Stock otherwise issuable pursuant to
the exercise of an option or the purchase of shares subject to an award or (ii)
by delivering to the Company shares of Common Stock already owned by the
optionee or award recipient. The shares so delivered or withheld shall have a
fair market value equal to such withholding obligation. The fair market value of
the shares used to satisfy such withholding obligation shall be determined by
the Company as of the date that the amount of tax to be withheld is to be
determined. An optionee or award recipient who has made an election pursuant to
this Section 21(a) may only satisfy his or her withholding obligation with
shares of Common Stock which are not subject to any repurchase, forfeiture,
unfulfilled vesting or other similar requirements.

     (b) If the recipient of an award under the Plan elects, in accordance with
Section 83(b) of the Code, to recognize ordinary income in the year of
acquisition of any shares awarded under the Plan, the Company will require at
the time of such election an additional payment for withholding tax purposes
based on the difference, if any, between the purchase price of such shares and
the fair market value of such shares as of the date immediately preceding the
date of the award.

22.  CANCELLATION AND NEW GRANT OF OPTIONS ETC.

     The Board of Directors shall have the authority to effect, at any time and
from time to time, with the consent of the affected optionees, (i) the
cancellation of any or all outstanding options under the Plan and the grant in
substitution therefor of new options under the Plan covering the same or
different numbers of shares of Common Stock and having an option exercise price
per share which may be lower or higher than the exercise price per share of the
cancelled options or (ii) the amendment of the terms of any and all outstanding
options under the Plan to provide an option exercise price per share which is
higher or lower than the then-current exercise price per share of such
outstanding options.

23.  EFFECTIVE DATE AND DURATION OF THE PLAN.

     (a) EFFECTIVE DATE. The Plan shall become effective when adopted by the
Board of Directors, but no Incentive Stock Option granted under the Plan shall
become exercisable unless and until the Plan shall have been approved by the
Company's shareholders. If such shareholder approval is not obtained within
twelve months after the date of the Board's adoption of the Plan, no options
previously granted under the Plan shall be deemed to be Incentive Stock Options
and no Incentive Stock Options shall be granted thereafter. Amendments to the
Plan not requiring shareholder approval shall become effective when adopted by
the Board of Directors; amendments requiring shareholder approval (as provided
in Section 20) shall become effective when adopted by the Board of Directors,
but no Incentive Stock Option issued after the date of such amendment shall
become exercisable (to the extent that such amendment to the Plan was required
to enable the Company to grant such Incentive Stock Option to a particular
optionee) unless and until such amendment shall have been approved by the
Company's shareholders. If such shareholder approval is not obtained within
twelve months of the Board's adoption of such amendment, any Incentive Stock
Options granted on or after the date of such amendment shall terminate to the
extent that such amendment to the Plan was required to enable the Company to
grant such option to a particular optionee. Subject to this limitation, options
and awards may be granted under the Plan at any time after the effective date
and before the date fixed for termination of the Plan.

     (b) TERMINATION. Unless sooner terminated in accordance with Section 17,
the Plan shall terminate, with respect to Incentive Stock Options, upon the
earlier of (i) the close of business on the day next preceding the tenth
anniversary of the date of its adoption by the Board of Directors, or (ii) the
date on which all shares available for issuance under the Plan shall have been
issued pursuant to the exercise or cancellation of options or the final vesting
of awards granted under the Plan. Unless sooner terminated in accordance with
Section 17, the Plan shall terminate with respect to options which are not
Incentive Stock Options and awards on the date specified in (ii) above. If the
date of termination is determined under (i) above, then options outstanding on
such date shall continue to have force and effect in accordance with the
provisions of the instruments evidencing such options.

24.  PROVISION FOR FOREIGN PARTICIPANTS.

     The Board of Directors may, without amending the Plan, modify awards or
options granted to participants who are foreign nationals or employed outside
the United States to recognize differences in laws, rules, regulations or
customs of such foreign jurisdictions with respect to tax, securities, currency,
employee benefit or other matters.
