Section 2.1 - Shares Subject to Plan

                                       6
<PAGE>

            (a)   The shares of stock subject to Options shall be shares of
Common Stock. The aggregate number of such shares of Common Stock which may be
issued upon exercise of Options shall not exceed 3,000,000. The shares of Common
Stock issuable upon exercise of such Options may be either previously authorized
but unissued shares or treasury shares.

            (b)   Notwithstanding the foregoing, if the offer or sale of shares
of stock under the Plan is subject to Section 260.140.45 of Title 10 of the
California Code of Regulations (or other applicable law limiting the offers or
sales of shares of stock under the Plan), the aggregate number of shares of
stock issuable upon the exercise of all outstanding Options (together with
options and similar awards outstanding under any other stock option plan of the
Company) and the total number of shares provided for under any stock bonus or
similar plan of the Company shall not exceed thirty percent (30%) (or such other
higher percentage limitation as may be approved by the stockholders of the
Company pursuant to Section 260.140.45) of the then outstanding shares of stock,
as calculated in accordance with the conditions and exclusions of Section
260.140.45 (or such other limitation under applicable law).

            (c)   No person shall be granted, in any calendar year, Options to
purchase more than 300,000 shares of Common Stock; provided, however, that the
foregoing limitation shall not apply prior to the Public Trading Date and,
following the Public Trading Date, the foregoing limitation shall not apply
until the earliest of: (i) the first material modification of the Plan
(including any increase in the number of shares reserved for issuance under the
Plan in accordance with Section 2.1); (ii) the issuance of all of the shares of
Common Stock reserved for issuance under the Plan; (iii) the expiration of the
Plan; (iv) the first meeting of stockholders at which Directors of the Company
are to be elected that occurs after the close of the third calendar year
following the calendar year in which the first registration of an equity
security of the Company under Section 12 of the Exchange Act occurred; or (v)
such other date required by Section 162(m) of the Code and the rules and
regulations promulgated thereunder. The foregoing limitation shall be adjusted
proportionately in connection with any change in the Company's capitalization as
described in Section 7.3. For purposes of this Section 2.1(c), to the extent
required by applicable law, if an Option is canceled in the same fiscal year of
the Company it was granted (other than in connection with a transaction
described in Section 7.3), the canceled Option will be counted against the limit
set forth in this Section 2.1(c). For this purpose, if the exercise price of an
Option is reduced, the transaction shall be treated as a cancellation of the
Option and the grant of a new Option.

Section 2.2 - Unexercised Options; Repurchased Restricted Stock

            If any Option expires or is cancelled without having been fully
exercised, the number of shares subject to such Option but as to which such
Option was not exercised prior to its expiration or cancellation may again be
optioned hereunder, subject to the limitations of Section 2.1. Furthermore, any
shares subject to Options which are adjusted pursuant to Section 7.3 and become
exercisable with respect to shares of stock of another corporation shall be
considered cancelled and may again be optioned hereunder, subject to the
limitations of Section 2.1. Shares of Common Stock which are delivered by the
Optionee or withheld by the Company upon the exercise of any Option under the
Plan, in payment of the exercise price thereof or tax withholding thereon, may
again be optioned hereunder, subject to the limitations of Section 2.1. If
shares of Restricted Stock are repurchased by the Company at their original
purchase price, the number of

                                       7
<PAGE>

such repurchased shares may again be optioned hereunder, subject to the
limitations of Section 2.1. Notwithstanding the provisions of this Section 2.2,
no shares of Common Stock may again be optioned if such action would cause an
Incentive Option to fail to qualify as an "incentive stock option" under Section
422 of the Code.

                                    ARTICLE 3

      granted Options;

                        (ii)  Determine the number of shares to be subject to

            (b)   Upon the selection of an executive or other key Employee or
      Consultant to be granted an Option, the Administrator shall instruct the

      of such Option as it deems appropriate.

            In consideration of the granting of an Option under the Plan, the
Optionee shall agree, in the Option Agreement, to remain in the employ of or to

Option) after the Option is granted.

subject to any additional limitations set forth in any applicable exemptive rule
under Section 16 of the Exchange Act (including any amendment to Rule 16b-3 of
the Exchange Act) that are requirements for the application of such exemptive
rule. To the extent permitted by applicable law, the Plan and Options granted or
awarded hereunder shall be deemed amended to the extent necessary to conform to
such applicable exemptive rule.

                                       10
<PAGE>

any Subsidiary or any Non-Corporate Affiliate or Consultants, in no event shall
an Option granted hereunder become vested and exercisable at a rate of less than
twenty percent (20%) per year of the shares of Common Stock subject thereto over
five (5) years from the date the Option is granted, subject to the continued
employment of the Optionee with the Company or the Subsidiaries or other
reasonable conditions established by the Administrator. At any time after grant
of an Option, the Administrator may, in its sole and absolute discretion and
subject to whatever terms and conditions it selects, accelerate the period
during which an Option granted to an Employee or Consultant vests.

            (b)   No portion of an Option which is unexercisable at Termination
of Employment or Termination of Consultancy, as the case may be, shall
thereafter become exercisable, except as may be otherwise provided by the
Administrator either in the Option Agreement or by action of the Administrator
following the grant of the Option.

            (c)   To the extent that the aggregate Fair Market Value of Common
Stock (and fair market value of other stock) with respect to which "incentive
stock options" (within the meaning of Section 422 of the Code, but without
regard to Section 422(d) of the Code) are exercisable for the first time by an
Optionee during any calendar year (under the Plan and all other incentive stock
option plans of the Company and any Subsidiary or Parent Corporation, within the
meaning of Section 422 of the Code), exceeds $100,000, such options shall be
treated as Non-Qualified Options to the extent required by Section 422 of the
Code. The rule set forth in the preceding sentence shall be applied by taking
options into account in the order in which they were granted. For purposes of
this Section, the Fair Market Value of Common Stock (or fair market value of
other stock) shall be determined as of the time the option with respect to such
Common Stock or other stock is granted.

            (d)   The Administrator may provide in the terms of an Option
Agreement that the Optionee may exercise the Option, at any time before the
termination of the Optionee's status as an Employee or Consultant, as
applicable, in whole or in part prior to the full vesting of the Option;
provided, however, that, subject to Section 7.12, shares of Common Stock
acquired upon exercise of an Option which has not fully vested may be subject to
any forfeiture, transfer or other restrictions as the Administrator may
determine in its sole discretion.

Section 4.5 - Expiration of Options

            (a)   Except as otherwise provided by the Administrator, no Option
may be exercised to any extent by anyone after the first to occur of the
following events:

                  (i)   The expiration of the term of the Option; or

                  (ii)  Except in the case of any Optionee who is disabled
      (within the meaning of Section 22(e)(3) of the Code), the expiration of
      three months from the date of the Optionee's Termination of Consultancy or
      Termination of Employment, as the case may be, for any reason other than
      such Optionee's death unless the Optionee dies within said three-month
      period; or

                  (iii) In the case of an Optionee who is disabled (within the
      meaning of Section 22(e)(3) of the Code), the expiration of one year from
      the date of the Optionee's

                                       11
<PAGE>

      Termination of Employment or Termination of Consultancy, as the case may
      be, for any reason other than such Optionee's death unless the Optionee
      dies within said one-year period; or

                  (iv)  The expiration of one year from the date of the
      Optionee's death.

            (b)   Subject to the provisions of Section 4.5(a), the Administrator
shall provide, in the terms of each individual Option, when such Option expires
and becomes unexercisable; and, without limiting the generality of the
foregoing, the Administrator may provide in the terms of individual Options that
said Options expire immediately upon a Termination of Employment or Termination
of Consultancy, as the case may be, for any reason; provided, however, that,
prior to the Public Trading Date, to the extent required by Section 25102(o) of
the California Corporations Code and Section 260.140.41 of Title 10 of the
California Code of Regulations (or other applicable law), the terms of an Option
shall provide that such Option may be exercised in the event of Termination of
Consultancy or Termination of Employment (other than for cause as defined by
applicable law, the Option Agreement or a contract of employment with the
Optionee), to the extent that such Option is exercisable on the date of such
Termination: (i) for a period of at least six months (or such longer period as
is required by applicable law) from the date of such termination if such
termination was caused by death or disability, and (ii) for a period of at least
30 days (or such longer period as is required by applicable law) from the date
of such termination if such termination was caused by reason other than the
death or disability of the Optionee.

            (c)   Except as limited by the requirements of Section 422 of the
Code and regulations and rulings thereunder applicable to Incentive Options, the
Administrator may extend the term of any outstanding Option in connection with
any Termination of Employment or Termination of Consultancy of the Optionee, or
amend any other term or condition of such Option relating to such a termination.

Section 4.6 - Substitute Awards

            Notwithstanding the foregoing provisions of this Article IV to the
contrary, in the case of an Option that is a Substitute Award, the price per
share of the shares subject to such Option may be less than the Fair Market
Value per share on the date of grant, provided, that:

                  (a)   the aggregate Fair Market Value (as of the date such
      Substitute Award is granted) of the shares subject to the Substitute
      Award, less the aggregate exercise price thereof, does not exceed;

                  (b)   the aggregate fair market value (as of the time
      immediately preceding the transaction giving rise to the Substitute Award,
      such fair market value to be determined by the Administrator) of the
      shares of the predecessor entity that were subject to the grant assumed or
      substituted for by the Company, less the aggregate exercise price of such
      shares.

Section 4.7 - Restrictions on Common Stock

                                       12
<PAGE>

            The Administrator may, in its sole discretion, provide under the
terms of an Option that shares of Common Stock purchased upon exercise of such
Option shall be subject to repurchase from the Optionee by the Company, or shall
be subject to such restrictions as the Administrator shall provide, which
restrictions may include, without limitation, restrictions concerning voting
rights and transferability and restrictions based on duration of employment with
the Company and the Subsidiaries, Company performance and individual
performance; provided, however, that, by action taken after the Common Stock is
purchased upon exercise of the Option, the Administrator may, on such terms and
conditions as it may determine to be appropriate, terminate the Company's
repurchase right or remove any or all of the restrictions imposed by the terms
of the Option Agreement; provided, further, that any restrictions shall be
subject to the requirements of Section 7.12 hereof. The Company's right to
repurchase the Common Stock from the Optionee then subject to the right may
provide that immediately upon a Termination of Employment or a Termination of
Consultancy, as applicable, and for such period as the Administrator shall
determine, the Company shall have the right to purchase the Common Stock at such
price per share as is determined by the Administrator and as provided under the
terms of an Option. Shares of Common Stock purchased upon the exercise of an
Option may not be sold, transferred or encumbered until any repurchase right and
any and all restrictions are terminated or expire. The Secretary of the Company
or such other escrow agent as the Administrator may appoint shall retain
physical custody of each certificate representing such shares of Common Stock
until the repurchase right and any and all of the restrictions imposed under the
Option Agreement with respect to the shares evidenced by such certificate
terminate, expire or shall have been removed. In order to enforce the
restrictions imposed upon shares of Common Stock hereunder, the Administrator
shall cause a legend or legends to be placed on certificates representing all
shares of Common Stock that are still subject to any repurchase right or
restrictions under Option Agreements, which legend or legends shall make
appropriate reference to the conditions imposed thereby. If an Optionee makes an
election under Section 83(b) of the Code, or any successor Section thereto, to
be taxed with respect to the Common Stock as of the date of transfer of the
Common Stock rather than as of the date or dates upon which the Optionee would
otherwise be taxable under Section 83(a) of the Code, the Optionee shall deliver
a copy of such election to the Company immediately after filing such election
with the Internal Revenue Service.

Section 4.8 - No Right to Employment

            Nothing in this Plan or in any Option Agreement hereunder shall
confer upon any Optionee any right to continue in the employ of or in a business
relationship with the Company, any Parent Corporation, any Subsidiary or any
Non-Corporate Affiliate or shall interfere with or restrict in any way the
rights of the Company, its Parent Corporations and its Subsidiaries, which are
hereby expressly reserved, to discharge or to terminate the business
relationship with, any Optionee at any time for any reason whatsoever, with or
without cause.

                               EXERCISE OF OPTIONS

Section 5.1 - Person Eligible to Exercise

            During the lifetime of the Optionee, only the Optionee may exercise
an Option (or any portion thereof) granted to the Optionee. After the death of
the Optionee, any exercisable portion of an Option may, prior to the time when
such portion becomes unexercisable under the Plan or the applicable Option
Agreement, be exercised by the Optionee's personal representative or by any
person empowered to do so under the deceased Optionee's will or under the then
applicable laws of descent and distribution.

Section 5.2 - Partial Exercise

            At any time and from time to time prior to the time when any
exercisable Option or exercisable portion thereof becomes unexercisable under
the Plan or the applicable Option Agreement, such Option or portion thereof may
be exercised in whole or in part; provided, however, that the Company shall not
be required to issue fractional shares and the Administrator may, by the terms
of the Option, require any partial exercise to be with respect to a specified
minimum number of shares.

Section 5.3 - Manner of Exercise

            An exercisable Option, or any exercisable portion thereof, may be
exercised solely by delivery to the Secretary or his office of all of the
following prior to the time when such Option or such portion becomes
unexercisable under the Plan or the applicable Option Agreement:

            (a)   Notice in writing signed by the Optionee or other person then
entitled to exercise such Option or portion thereof, stating that such Option or
portion thereof is exercised, such notice complying with all applicable rules
established by the Administrator.

            (b)   Full cash payment to the Secretary of the Company for the
shares with respect to which the Option, or portion thereof, is exercised.
However, the Administrator may, in its discretion (i) allow payment, in whole or
in part, through the delivery of shares of Common Stock which have been owned by
the Optionee for at least six months, duly endorsed for transfer to the Company
with a Fair Market Value on the date of delivery equal to the aggregate exercise
price of the Option or exercised portion thereof; (ii) allow payment, in whole
or in part, through the delivery of property of any kind which constitutes good
and valuable consideration; (iii) allow payment, in whole or in part, through
the delivery of a notice that the Optionee has placed a market sell order with a
broker with respect to shares of Common Stock then issuable upon exercise of the
Option, and that the broker has been directed to pay a sufficient portion of the
net proceeds of the sale to the Company in satisfaction of the Option exercise
price, provided that payment of such proceeds is then made to the Company upon
settlement of such sale; or (iv) allow payment through any combination of the
consideration provided in the foregoing paragraphs (i), (ii) and (iii);
provided, however, that the payment in the manner prescribed in the preceding
paragraphs shall not be permitted to the extent that the Administrator
determines that payment in such manner shall result in an extension or
maintenance of credit, an arrangement for

                                       14
<PAGE>

the extension of credit, or a renewal of an extension of credit in the form of a
personal loan to or for any executive officer of the Company that is prohibited
by Section 13(k) of the Exchange Act or other applicable law.

            (c)   The payment to the Company (or other employer corporation) of
the amounts which it is required to withhold under federal, state or local law
in connection with the exercise of the Option; with the consent of the
Administrator, (i) shares of the Company's Common Stock owned by the Optionee
duly endorsed for transfer or (ii) shares of the Company's Common Stock issuable
to the Optionee upon exercise of the Option, valued at Fair Market Value at the
date of Option exercise, may be used to make all or part of such payment;
provided, however, that the number of shares of Common Stock used in order to
satisfy the Optionee's federal and state income and payroll tax liabilities
shall be limited to the number of shares that have a Fair Market Value on the
date of withholding equal to the aggregate amount of such liabilities based on
the minimum statutory withholding rates for federal and state tax income and
payroll tax purposes that are applicable to such supplemental taxable income.

            (d)   Such representations and documents as the Administrator, in
its absolute discretion, deems necessary or advisable to effect compliance with
all applicable provisions of the Securities Act and any other federal or state
securities laws or regulations. The Administrator may, in its absolute
discretion, also take whatever additional actions it deems appropriate to effect
such compliance including, without limitation, placing legends on share
certificates and issuing stop-transfer orders to transfer agents and registrars.

            (e)   Upon the exercise of all or a portion of an unvested Option
pursuant to Section 4.4(d), a restricted stock purchase agreement, an escrow
agreement and such other agreements as are required by the Administrator in
forms determined by the Administrator and signed by the Optionee or other person
then entitled to exercise the Option or such portion of the Option.

            (f)   In the event that the Option or portion thereof shall be
exercised pursuant to Section 5.1 by any person or persons other than the
Optionee, appropriate proof of the right of such person or persons to exercise
the Option or portion thereof.

Section 5.4 - Additional Limitations on Exercise of Options

            In addition to any other limitations on the settlement or exercise
of an Option, the Optionee may be required to comply with any timing or other
restrictions with respect to the settlement or exercise of an Option, including
a window-period limitation, as may be imposed in the discretion of the
Administrator relating to compliance with the Exchange Act and the rules and
regulations thereunder and other applicable law.

Section 5.5 - Conditions to Issuance of Stock Certificates

            The shares of stock issuable and deliverable upon the exercise of an
Option, or any portion thereof, may be either previously authorized but unissued
shares or issued shares which have then been reacquired by the Company. The
Company shall not be required to issue or deliver any certificate or
certificates for shares of stock purchased upon the exercise of any Option or
portion thereof prior to fulfillment of all of the following conditions:

                                       15
<PAGE>

            (a)   The admission of such shares to listing on all stock exchanges
on which such class of stock is then listed; and

            (b)   The completion of any registration or other qualification of
such shares under any state or federal law or under the rulings or regulations
of the Securities and Exchange Commission or any other governmental regulatory
body, which the Administrator shall, in its absolute discretion, deem necessary
or advisable; and

            (c)   The obtaining of any approval or other clearance from any
state or federal governmental agency which the Administrator shall, in its
absolute discretion, determine to be necessary or advisable; and

            (d)   The payment to the Company (or other employer corporation) of
all amounts which it is required to withhold under federal, state or local law
in connection with the exercise of the Option; and

            (e)   The lapse of such reasonable period of time following the
exercise of the Option as the Administrator may establish from time to time for
reasons of administrative convenience.

Section 5.6 - Rights as Stockholders

            Optionees shall not be, nor have any of the rights or privileges of,
stockholders of the Company in respect of any shares purchasable upon the
exercise of any part of an Option unless and until certificates representing
such shares have been issued by the Company to such Optionees.

Section 5.7 - Notice of Transfer of Common Stock

            The Optionee shall give the Company prompt notice of any disposition
of shares of Common Stock acquired by exercise of an Incentive Option within (a)
two years from the date of granting (including the date the Option is modified,
extended or renewed for purposes of Section 424(h) of the Code) such Option to
such Optionee or (b) one year after the transfer of such shares to such
Optionee.

                                    ARTICLE 6

                                 ADMINISTRATION

Section 6.1 - Administration of the Plan

            (a)   The Plan shall be administered by the Administrator.

            (b)   Prior to the Effective Time, the Administrator shall be Dr.
Joseph A. Sorge. Should Dr. Sorge resign as Administrator or cease to be a
Director, a successor Director shall be elected by majority vote of the Board.
Such Director shall serve until such time as such person ceases to be a
Director. Notwithstanding the foregoing, however, from and after the Effective
Time, a Committee of the Board shall administer the Plan and the Committee shall
consist solely of two or more Independent Directors each of whom is both an
"outside director," within the

                                       16
<PAGE>

meaning of Section 162(m) of the Code, and a "non-employee director" within the
meaning of Rule 16b-3. The Board may abolish the Committee at any time and
revest in the Board the administration of the Plan. Appointment of Committee
members shall be effective upon acceptance of appointment. Committee members may
resign at any time by delivering written notice to the Board. Vacancies in the
Committee may be filled by the Board.

Section 6.2 - Duties and Powers of Administrator

            It shall be the duty of the Administrator to conduct the general
administration of the Plan in accordance with its provisions. The Administrator
shall have the power to interpret the Plan and the Options and to adopt such
rules for the administration, interpretation and application of the Plan as are
consistent therewith and to interpret, amend or revoke any such rules and to
amend any Option Agreement, provided that the rights or obligations of the
Optionee of the Option that is the subject of any such Option Agreement are not
affected adversely thereby. Any such Option Agreement under the Plan need not be
the same with respect to each Optionee. Any such interpretations and rules with
respect to Incentive Options shall be consistent with the provisions of Section
422 of the Code.

Section 6.3 - Majority Rule

            The Administrator shall act (a) individually, if Dr. Sorge or a
Director who is a successor, is appointed in accordance with Section 6.1(b) is
the Administrator, (b) by a majority of the members of the Committee, if the
Committee is the Administrator, or (c) by a majority of the members of the
Board, if the Board is the Administrator. The Committee or Board may act either
by vote at a meeting or by a memorandum or other written instrument signed by a
majority of the Committee or the Board, as applicable.

Section 6.4 - Compensation; Professional Assistance; Good Faith Actions

            Members of the Administrator shall receive compensation for their
services as members as determined by the Board. All expenses and liabilities
incurred by members of the Administrator in connection with the administration
of the Plan shall be borne by the Company. The Administrator may employ
attorneys, consultants, accountants, appraisers, brokers or other persons. The
Administrator, the Company and its officers and Directors shall be entitled to
rely upon the advice, opinions or valuations of any such persons. All actions
taken and all interpretations and determinations made by the Administrator in
good faith shall be final and binding upon all Optionees, the Company and all
other interested persons. No member of the Administrator shall be personally
liable for any action, determination or interpretation made in good faith with
respect to the Plan or the Options, and all members of the Administrator shall
be fully protected by the Company in respect of any such action, determination
or interpretation.

Section 6.5 - Delegation of Authority to Grant Options

            Prior to the Public Trading Date, the Administrator may, but need
not, delegate from time to time some or all of its authority to grant Options
under the Plan to a subcommittee consisting of one or more members of the Board
or of one or more officers of the Company;

                                       17
<PAGE>

provided, further, that after the Public Trading Date, the Administrator may,
but need not, delegate from time to time some or all of its authority to grant
awards under the Plan to a committee consisting of one or more members of the
Administrator or of one or more officers of the Company; provided, however, that
after the Public Trading Date, the Administrator may not delegate its authority
to grant awards to individuals (a) who are subject on the date of the grant to
the reporting rules under Section 16(a) of the Exchange Act, (b) whose
compensation may be subject to the limit on deductible compensation imposed by
Section 162(m) of the Code, or (c) who are officers of the Company who are
delegated authority by the Administrator hereunder. Any delegation hereunder
shall be subject to the restrictions and limits that the Administrator specifies
at the time of such delegation of authority and may be rescinded at any time by
the Administrator. At all times, any subcommittee appointed under this Section
6.5 shall serve in such capacity at the pleasure of the Administrator.

Section 6.6 - Repricing of Options

            Subject to Section 7.3, the Administrator shall not, without the
approval of the stockholders of the Company, authorize the amendment of any
outstanding Option to reduce its price per share. Furthermore, no Option shall
be canceled and replaced with the grant of an Option having a lesser price per
share without the further approval of stockholders of the Company.

                                    ARTICLE 7

                                OTHER PROVISIONS

Section 7.1 - Options Not Transferable

            No Option or interest or right therein or part thereof shall be
liable for the debts, contracts or engagements of the Optionee or his successors
in interest or shall be subject to disposition by transfer, alienation,
anticipation, pledge, encumbrance, assignment or any other means whether such
disposition be voluntary or involuntary or by operation of law by judgment,
levy, attachment, garnishment or any other legal or equitable proceedings
(including bankruptcy), and any attempted disposition thereof shall be null and
void and of no effect; provided, however, that nothing in this Section 7.1 shall
prevent transfers by will or by the applicable laws of descent and distribution.
In addition, in the case of a Non-Qualified Option, nothing in this Section 7.1
shall, to the extent permitted by applicable law, prevent transfers 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 (settlor), or by gift
to "immediate family" as that term is defined in 17 C.F.R. 240.16a-1(e).

Section 7.2 - Amendment, Suspension or Termination of the Plan

            The Plan may be wholly or partially amended or otherwise modified,
suspended or terminated at any time or from time to time by the Administrator.
However, without approval of the Company's stockholders given within 12 months
before or after the action by the Administrator, no action of the Administrator
may, except as provided in Section 7.3, increase any limit imposed in Section
2.1 on the maximum number of shares which may be issued on exercise of Options
or amend the Plan in any other manner that would otherwise require approval by
the Company's stockholders as a matter of applicable law, regulation or rule.
Neither the amendment, suspension nor termination of the Plan shall, without the
consent of the Optionee of

                                       18
<PAGE>

the Option, impair any rights or obligations under any Option theretofore
granted. No Option may be granted during any period of suspension nor after
termination of the Plan, and in no event may any Option be granted under this
Plan after May 31, 2014.

Section 7.3 - Changes in Common Stock or Assets of the Company,
            Acquisition or Liquidation of the Company and Other Corporate Events

            (a)   In the event that the Administrator determines that any
dividend or other distribution (whether in the form of cash, Common Stock, other
securities, or other property), recapitalization, reclassification, stock split,
reverse stock split, reorganization, merger, consolidation, split-up, spin-off,
combination, repurchase, liquidation, dissolution, or sale, transfer, exchange
or other disposition of all or substantially all of the assets of the Company,
or exchange of Common Stock or other securities of the Company, issuance of
warrants or other rights to purchase Common Stock or other securities of the
Company, or other similar corporate transaction or event, in the Administrator's
sole and absolute discretion, affects the Common Stock such that an adjustment
is determined by the Administrator to be appropriate in order to prevent
dilution or enlargement of the benefits or potential benefits intended to be
made available under the Plan or with respect to an Option or Restricted Stock,
then the Administrator shall, in such manner as it may deem equitable, adjust
any or all of

                  (i)   the number and kind of shares of Common Stock (or other
      securities or property) with respect to which Options may be granted or
      awarded (including, but not limited to, adjustments of the limitations in
      Section 2.1 on the maximum number and kind of shares which may be issued),

                  (ii)  the number and kind of shares of Common Stock (or other
      securities or property) subject to outstanding Options or Restricted
      Stock, and

                  (iii) the grant or exercise price with respect to any Option.

Any such adjustment made by the Administrator shall be final and binding upon
the Optionees, the Company and all other interested persons.

            (b)   In the event of any transaction or event described in 7.3(a)
or any unusual or nonrecurring transactions or events affecting the Company, any
affiliate of the Company, or the financial statements of the Company or any
affiliate, or of changes in applicable laws, regulations, or accounting
principles, the Administrator, in its sole and absolute discretion, and on such
terms and conditions as it deems appropriate, either by the terms of the Option
or Restricted Stock or by action taken prior to the occurrence of such
transaction or event and either automatically or upon the Optionee's request, is
hereby authorized to take any one or more of the following actions whenever the
Administrator determines that such action is appropriate in order to prevent
dilution or enlargement of the benefits or potential benefits intended to be
made available under the Plan or with respect to any Option or Restricted Stock
under the Plan, to facilitate such transactions or events or to give effect to
such changes in laws, regulations or principles:

                  (i)   To provide for either the purchase of any such Option or
      Restricted Stock for an amount of cash equal to the amount that could have
      been attained upon the exercise of such Option or realization of the
      Optionee's rights had such Option

                                       19
<PAGE>

      or Restricted Stock been currently exercisable or payable or fully vested
      or the replacement of such Option or Restricted Stock with other rights or
      property selected by the Administrator in its sole discretion;

                  (ii)  To provide that the Option cannot vest, be exercised or
      become payable after such event;

                  (iii) To provide that such Option shall be exercisable as to
      all shares covered thereby, notwithstanding anything to the contrary in
      Section 4.4 or 4.6 or the provisions of such Option;

                  (iv)  To provide that such Option or Restricted Stock be
      assumed by the successor or survivor corporation, or a parent or
      subsidiary thereof, or shall be substituted for by similar options, rights
      or awards covering the stock of the successor or survivor corporation, or
      a parent or subsidiary thereof, with appropriate adjustments as to the
      number and kind of shares and prices; and

                  (v)   To make adjustments in the number and type of shares of
      Common Stock (or other securities or property) subject to outstanding
      Options, and in the number and kind and conditions of (including the grant
      or exercise price), and the criteria included in, outstanding options,
      rights and awards and options, rights and awards which may be granted in
      the future.

            (c)   With respect to Options which are intended to qualify as
performance-based compensation under Section 162(m)(4)(C), no adjustment or
action described in this Section 7.3 or in any other provision of the Plan shall
be authorized to the extent that such adjustment or action would cause such
Option to fail to so qualify under Section 162(m)(4)(C), or any successor
provisions thereto. No adjustment or action described in this Section 7.3 or in
any other provision of the Plan shall be authorized to the extent that such
adjustment or action would cause the Plan to violate Section 422(b)(1) of the
Code. Furthermore, no such adjustment or action shall be authorized to the
extent such adjustment or action would result in short-swing profits liability
under Section 16 or violate the exemptive conditions of Rule 16b-3 unless the
Administrator determines that the Option is not to comply with such exemptive
conditions. The number of shares of Common Stock subject to any Option shall
always be rounded up to the next whole number.

            (d)   Subject to the provisions of the Plan, the Administrator may,
in its discretion, include such further provisions and limitations in any
Option, agreement or certificate, as it may deem equitable and in the best
interests of the Company.

            (e)   The existence of the Plan, any Option Agreement or Restricted
Stock purchase agreement and the Options granted hereunder shall not affect or
restrict in any way the right or power of the Company or the stockholders of the
Company to make or authorize any adjustment, recapitalization, reorganization or
other change in the Company's capital structure or its business, any merger or
consolidation of the Company, any issue of stock or of options, warrants or
rights to purchase stock or of bonds, debentures, preferred or prior preference
stocks whose rights are superior to or affect the Common Stock or the rights
thereof or which are convertible into or exchangeable for Common Stock, or the
dissolution or liquidation of the

                                       20

otherwise.

            This Plan shall be submitted for the approval of the Company's
stockholders within 12 months after the date of the Board's adoption of the
Plan. Options may be granted prior to such stockholder approval; provided,
however, that such Options shall not be exercisable prior to the time when the
Plan is approved by the stockholders; provided, further, that if such approval
has not been obtained at the end of said 12-month period, all Options previously
granted under the Plan shall thereupon be cancelled and become null and void.

Section 7.5 - Effect of Plan upon Other Option and Compensation Plans

construed to limit the right of the Company, any Parent Corporation, any
Subsidiary or any Non-Corporate Affiliate (a) to establish any other forms of
incentives or compensation for employees of the Company, any Parent Corporation,
any Subsidiary or any Non-Corporate Affiliate or (b) to grant or assume options
otherwise than under this Plan in connection with any proper corporate purpose,

deduction from other compensation payable to each Optionee of any sums required
by federal, state or local tax law to be withheld with respect to the issuance,
vesting, exercise or payment of any Option. The Administrator may in its
discretion and in satisfaction of the foregoing requirement allow such Optionee
to elect to have the Company withhold shares of Common Stock otherwise issuable
under such Option (or allow the return of shares of Common Stock) having a fair
market value equal to the minimum sums required to be withheld. Notwithstanding
any other provision of the Plan, the number of shares of Common Stock which may
be withheld with respect to the issuance, vesting, exercise or payment of any
Option (or which may be repurchased from the Optionee within six months after
such shares of Common Stock were acquired by the Optionee from the Company) in
order to satisfy the Optionee's federal and state income and payroll tax
liabilities with respect to the issuance, vesting, exercise or payment of the
Option shall be limited to the number of shares which have a Fair Market Value
on the date of withholding or repurchase equal to the aggregate amount of such
liabilities based on the minimum statutory withholding rates for federal and
state income tax and payroll tax purposes that are applicable to such
supplemental taxable income.

<PAGE>

Options made under the Plan, or to require an Optionee to agree by separate
written instrument, that (a) (i) any proceeds, gains or other economic benefit
actually or constructively received by the Optionee upon any receipt or exercise
of the Option, or upon the receipt or resale of any Common Stock underlying the
Option, must be paid to the Company, and (ii) the Option shall terminate and any
unexercised portion of the Option (whether or not vested) shall be forfeited, if
(b)(i) a Termination of Consultancy or Termination of Employment occurs prior to
a specified date, or within a specified time period following receipt or
exercise of the Option, or (ii) the Optionee at any time, or during a specified
time period, engages in any activity in competition with the Company, or which
is inimical, contrary or harmful to the interests of the Company, as further
defined by the Administrator or (iii) the Optionee incurs a Termination of
Consultancy or Termination of Employment for cause.

during the period such Optionee holds an Option, and, in the case of an Optionee
or other person who acquires shares of Common Stock pursuant to the Plan, during
the period such Optionee or person owns such shares, copies of the Company's
annual financial statements. Notwithstanding the preceding sentence, the Company
shall not be required to provide such statements to Employees and Consultants
whose duties in connection with the Company assure their access to equivalent
information.

Section 7.9 - Investment Intent

            The Company may require an Optionee or other person purchasing
shares of Common Stock, as a condition of exercising or acquiring Common Stock
under any Option, to give written assurances satisfactory to the Company as to
the Optionee's or other person's knowledge and experience in financial and
business matters and/or to employ a representative reasonably satisfactory to
the Company who is knowledgeable and experienced in financial and business
matters and that such Optionee or person is capable of evaluating, alone or
together with the representative, the merits and risks of exercising the Option;
and to give written assurances satisfactory to the Company stating that the
person is acquiring the stock subject to the Option for such Optionee or
person's own account and not with any present intention of selling or otherwise
distributing the Common Stock. The foregoing requirements, and any assurances
given pursuant to such requirements, shall be inoperative if the issuance of the
shares upon the exercise or acquisition of Common Stock under the applicable
Option has been registered under a then currently effective registration
statement under the Securities Act, or as to any particular requirement, a
determination is made by counsel for the Company that such requirement need not
be met in the circumstances under the then applicable securities laws. The
Company may, upon advice of counsel to the Company, place legends on stock
certificates issued under the Plan as such counsel deems necessary or
appropriate in order to comply with applicable securities laws, including, but
not limited to, legends restricting the transfer of the stock.

number of shares of Common Stock (subject to adjustment as provided in Section

which may be adopted by the Administrator from time to time.

                  (a)   The price per share of the shares subject to each Option
      granted to an Independent Director pursuant to Section 3.2 of the Plan
      shall equal 100% of the Fair Market Value of a share of Common Stock on
      the date the Option is granted. Options granted to Independent Directors
      pursuant to Section 3.2 of the Plan shall become

      granted to an Independent Director pursuant to Section 3.3 of the Plan
      shall be set by the Administrator; provided, however, that such price
      shall be no less than 85% of the Fair Market Value of a share of Common
      Stock on the date the Option is granted. The period during which the right
      to exercise, in whole or in part, an Option granted to an Independent
      Director pursuant to Section 3.3 of the Plan shall be set by the
      Administrator.

                  (c)   At any time after grant of an Option, the Administrator
      may, in its sole and absolute discretion and subject to whatever terms and
      conditions it selects, accelerate the period during which an Option
      granted to an Independent Director vests.

                  (d)   Subject to Section 4.6, the term of each Option granted
      to an Independent Director shall be 10 years from the date the Option is
      granted. No portion of an Option which is unexercisable at Termination of
      Directorship shall thereafter become exercisable.

            4.1.  Partial Exercise. An exercisable Option may be exercised in
whole or in part. However, an Option shall not be exercisable with respect to

                  (b)   Such representations and documents as the Administrator,
      in its absolute discretion, deems necessary or advisable to effect
      compliance with all applicable provisions of the Securities Act and any
      other federal or state securities laws or regulations. The Administrator
      may, in its absolute discretion, also take whatever additional actions it
      deems appropriate to effect such compliance including, without

                                       5

      limitation, placing legends on share certificates and issuing
      stop-transfer notices to agents and registrars;

                  (c)   In the event that the Option shall be exercised pursuant

                  (d)   Full cash payment to the Secretary of the Company for
      the shares with respect to which the Option, or portion thereof, is
      exercised. However, the Administrator may, in its discretion, (i) allow

      Stock which have been owned by the Holder for at least six months, duly
      endorsed for transfer to the Company with a Fair Market Value on the date
      of delivery equal to the aggregate exercise price of the Option or
      exercised portion thereof; (ii) allow payment, in whole or in part,
      through the delivery of property of any kind which constitutes good and
      valuable consideration; (iii) allow payment, in whole or in part, through
      the delivery of a notice that the Holder has placed a market sell order
      with a broker with respect to shares of Common Stock then issuable upon
      exercise of the Option, and that the broker has been directed to pay a
      sufficient portion of the net proceeds of the sale to the Company in
      satisfaction of the Option exercise price, provided that payment of such
      proceeds is then made to the Company upon settlement of such sale; or (iv)
      allow payment through any combination of the consideration provided in the
      foregoing subparagraphs (i), (ii) and (iii).

            4.3.  Conditions to Issuance of Stock Certificates. The Company

shares of stock purchased upon the exercise of any Option or portion thereof
prior to fulfillment of all of the following conditions:

      qualification of such shares under any state or federal law, or under the
      rulings or regulations of the Securities and Exchange Commission or any
      other governmental regulatory body which the Administrator shall, in its
      absolute discretion, deem necessary or advisable;

                  (c)   The obtaining of any approval or other clearance from
      any state or federal governmental agency which the Administrator shall, in
      its absolute discretion, determine to be necessary or advisable;

                  (d)   The lapse of such reasonable period of time following
      the exercise of the Option as the Administrator may establish from time to
      time for reasons of administrative convenience; and

                  (e)   The receipt by the Company of full payment for such
      shares, including payment of any applicable withholding tax, which in the
      discretion of the

<PAGE>

      Administrator may be in the form of consideration used by the Holder to
      pay for such shares under Section 4.2(d).

            4.4.  Rights as Stockholders. Holders shall not be, nor have any of
the rights or privileges of, stockholders of the Company in respect of any
shares purchasable upon the exercise of any part of an Option unless and until
certificates representing such shares have been issued by the Company to such
Holders.

            4.5.  Exercise, Ownership and Transfer Restrictions. The
Administrator, in its absolute discretion, may impose such restrictions on the
exercise of an Option and the ownership and transferability of the shares
purchasable upon the exercise of an Option as it deems appropriate. Any such
restriction shall be set forth in the respective Option Agreement and may be
referred to on the certificates evidencing such shares.

            4.6.  Limitations on Exercise of Options Granted to Independent
Directors. No Option granted to an Independent Director may be exercised to any
extent by anyone after the first to occur of the following events:

                  (a)   The expiration of 12 months from the date of the
      Holder's death;

                  (b)   The expiration of 12 months from the date of the
      Holder's Termination of Directorship by reason of his or her permanent and
      total disability (within the meaning of Section 22(e)(3) of the Code);

                  (c)   The expiration of three months from the date of the
      Holder's Termination of Directorship for any reason other than such
      Holder's death or his or her permanent and total disability, unless the
      Holder dies within said three-month period; or

                  (d)   The expiration of 10 years from the date the Option was
      granted.

            4.7.  Additional Limitations on Exercise of Options. Holders may be
required to comply with any timing or other restrictions with respect to the
settlement or exercise of an Option, including a window-period limitation, as
may be imposed in the discretion of the Administrator.

                                  ARTICLE VII.

                                 ADMINISTRATION

            5.1.  Duties and Powers of Administrator. It shall be the duty of
the Board to conduct the general administration of the Plan in accordance with
its provisions. The Board shall have the power to interpret the Plan and the
Option Agreements, and to adopt such rules for the administration,
interpretation and application of the Plan as are consistent therewith, and to
interpret, amend or revoke any such rules. The Board shall also have the power
to amend any Option Agreement provided that the rights or obligations of the
Holder of the Option that is the subject of any such Option Agreement are not
affected adversely thereby; provided, however,

                                       7
<PAGE>

that without the approval of the stockholders of the Company, the Board shall
not authorize the amendment of any outstanding Option to reduce its exercise
price. Notwithstanding anything contained herein, no Option shall be canceled
and replaced with the grant of an Option having a lower exercise price without
the approval of the stockholders of the Company. Grants under the Plan need not
be the same with respect to each Holder.

            5.2.  Professional Assistance; Good Faith Actions. All expenses and
liabilities which members of the Board incur in connection with the
administration of the Plan shall be borne by the Company. The Board may employ
attorneys, consultants, accountants, appraisers, brokers or other persons. The
Board, the Company and the Company's officers and Directors shall be entitled to
rely upon the advice, opinions or valuations of any such persons. All actions
taken and all interpretations and determinations made by the Board in good faith
shall be final and binding upon all Holders, the Company and all other
interested persons. No members of the Board shall be personally liable for any
action, determination or interpretation made in good faith with respect to the
Plan or Options, and all members of the Board shall be fully protected by the
Company in respect of any such action, determination or interpretation.

                                   ARTICLE XI.

                            MISCELLANEOUS PROVISIONS

            6.1.  Not Transferable.

                  (a)   No Option under the Plan may be sold, pledged, assigned
      or transferred in any manner other than by will or the laws of descent and
      distribution or, subject to the consent of the Administrator, pursuant to
      a DRO, unless and until such Option has been exercised, or the shares
      underlying such Option have been issued, and all restrictions applicable
      to such shares have lapsed. No Option or interest or right therein shall
      be liable for the debts, contracts or engagements of the Holder or his or
      her successors in interest or shall be subject to disposition by transfer,
      alienation, anticipation, pledge, encumbrance, assignment or any other
      means whether such disposition be voluntary or involuntary or by operation
      of law by judgment, levy, attachment, garnishment or any other legal or
      equitable proceedings (including bankruptcy), and any attempted
      disposition thereof shall be null and void and of no effect, except to the
      extent that such disposition is permitted by the preceding sentence.

                  (b)   During the lifetime of the Holder, only he or she may
      exercise an Option (or any portion thereof) granted to him or her under
      the Plan, unless it has been disposed of with the consent of the
      Administrator pursuant to a DRO. After the death of the Holder, any
      exercisable portion of an Option may, prior to the time when such portion
      becomes unexercisable under the Plan or the applicable Option Agreement,
      be exercised by his or her personal representative or by any person
      empowered to do so under the deceased Holder's will or under the then
      applicable laws of descent and distribution.

                                       8

            6.2.  Amendment, Suspension or Termination of the Plan. Except as
otherwise provided in this Section 6.2, the Plan may be wholly or partially
amended or otherwise modified, suspended or terminated at any time or from time
to time by the Administrator. However, without approval of the Company's
stockholders before or after the action by the Administrator, no action of the
Administrator may, except as provided in Section 6.3, increase the limits
imposed in Section 2.1 on the maximum number of shares which may be issued under
the Plan, and no action of the Administrator may be taken that would otherwise
require approval by the Company's stockholders as a matter of applicable law,
regulation or rule. No amendment, suspension or termination of the Plan shall,
without the consent of the Holder, alter or impair any rights or obligations
under any Option theretofore granted, unless the Option itself otherwise
expressly so provides. No Options may be granted during any period of suspension
or after termination of the Plan. Unless sooner terminated in accordance with
this Section 6.2, the Plan shall terminate on May 31, 2014.

            6.3.  Changes in Common Stock or Assets of the Company, Acquisition
or Liquidation of the Company and Other Corporate Events.

                  (a)   In the event that the Administrator determines that any
      dividend or other distribution (whether in the form of cash, Common Stock,
      other securities or other property), recapitalization, reclassification,
      stock split, reverse stock split, reorganization, merger, consolidation,
      split-up, spin-off, combination, repurchase, liquidation, dissolution, or
      sale, transfer, exchange or other disposition of all or substantially all
      of the assets of the Company, or exchange of Common Stock or other
      securities of the Company, issuance of warrants or other rights to
      purchase Common Stock or other securities of the Company, or other similar
      corporate transaction or event, in the Administrator's sole discretion,
      affects the Common Stock such that an adjustment is determined by the
      Administrator to be appropriate in order to prevent dilution or
      enlargement of the benefits or potential benefits intended to be made
      available under the Plan or with respect to an Option, then the
      Administrator shall, in such manner as it may deem equitable, adjust any
      or all of:

                        (i)   The number and kind of shares of Common Stock (or
            other securities or property) with respect to which Options may be
            granted;

                        (ii)  The number and kind of shares of Common Stock (or
            other securities or property) subject to outstanding Options; and

                        (iii) The grant or exercise price with respect to any
            Options.

                  (b)   Subject to Section 6.3(c), in the event of any
      transaction or event described in Section 6.3(a) or any unusual or
      nonrecurring transactions or events affecting the Company, any affiliate
      of the Company, or the financial statements of the Company or any
      affiliate, or of changes in applicable laws, regulations or accounting

                                       9
<PAGE>

      principles, the Administrator, in its sole and absolute discretion, and on
      such terms and conditions as it deems appropriate, either by the terms of
      the Option or by action taken prior to the occurrence of such transaction
      or event and either automatically or upon the Holder's request, is hereby
      authorized to take any one or more of the following actions whenever the
      Administrator determines that such action is appropriate in order to
      prevent dilution or enlargement of the benefits or potential benefits
      intended to be made available under the Plan or with respect to any Option
      under the Plan, to facilitate such transactions or events or to give
      effect to such changes in laws, regulations or principles:

                        (i)   To provide for either the purchase of any such
            Option for an amount of cash equal to the amount that could have
            been attained upon the exercise of such Option or realization of the
            Holder's rights had such Option been currently exercisable or
            payable or fully vested or the replacement of such Option with other
            rights or property selected by the Administrator in its sole
            discretion;

                        (ii)  To provide that the Option cannot vest, be
            exercised or become payable after such event;

                        (iii) To provide that such Option shall be exercisable
            as to all shares covered thereby, notwithstanding anything to the
            contrary in Section 3.4 or the provisions of such Option;

                        (iv)  To provide that such Option be assumed by the
            successor or survivor corporation, or a parent or subsidiary
            thereof, or shall be substituted for by similar options or rights
            covering the stock of the successor or survivor corporation, or a
            parent or subsidiary thereof, with appropriate adjustments as to the
            number and kind of shares and prices; and

                        (v)   To make adjustments in the number and type of
            shares of Common Stock (or other securities or property) subject to
            outstanding Options.

                  (c)   The Administrator may, in its discretion, include such
      further provisions and limitations in any Option, agreement or
      certificate, as it may deem equitable and in the best interests of the
      Company.

                  (d)   The existence of the Plan, the Option Agreement and the
      Options granted hereunder shall not affect or restrict in any way the
      right or power of the Company or the stockholders of the Company to make
      or authorize any adjustment, recapitalization, reorganization or other
      change in the Company's capital structure or its business, any merger or
      consolidation of the Company, any issue of stock or of options, warrants
      or rights to purchase stock or of bonds, debentures, preferred or prior
      preference stocks whose rights are superior to or affect the Common Stock
      or the rights thereof or which are convertible into or exchangeable for
      Common Stock, or the dissolution or

                                       10
<PAGE>

      liquidation of the Company, or any sale or transfer of all or any part of
      its assets or business, or any other corporate act or proceeding, whether
      of a similar character or otherwise.

            6.4.  Approval of Plan by Stockholders. The Plan will be submitted
for the approval of the Company's stockholders after the date of the Board's
initial adoption of the Plan, and any amendment to the Plan increasing the
aggregate number of shares of Common Stock issuable under the Plan will be
submitted for the approval of the Company's stockholders after the date of the
Board's adoption of such amendment. Options may be granted prior to such
stockholder approval, provided that such Options shall not be exercisable nor
shall such Options vest prior to the time when the Plan is approved by the
stockholders, and provided further that if such approval is not obtained, all
Options previously granted under the Plan shall thereupon be canceled and become
null and void.

            6.5.  Forfeiture Provisions. Pursuant to its general authority to
determine the terms and conditions applicable to Options under the Plan, the
Administrator shall, to the extent permitted by applicable law, have the right
to provide, in the terms of Options made under the Plan, or to require a Holder
to agree by separate written instrument, that (a)(i) any proceeds, gains or
other economic benefit actually or constructively received by the Holder upon
any receipt or exercise of the Option, or upon the receipt or resale of any
Common Stock underlying the Option, must be paid to the Company, and (ii) the
Option shall terminate and any unexercised portion of the Option (whether or not
vested) shall be forfeited, if (b)(i) a Termination of Directorship occurs prior
to a specified date, or within a specified time period following receipt or
exercise of the Option, or (ii) the Holder at any time, or during a specified
time period, engages in any activity in competition with the Company, or which
is inimical, contrary or harmful to the interests of the Company, as further
defined by the Administrator, or (iii) the Holder incurs a Termination of
Directorship for cause.

            6.6.  Effect of Plan Upon Options and Compensation Plans. The
adoption of the Plan shall not affect any other compensation or incentive plans
in effect for the Company, any Subsidiary or any Noncorporate Affiliate. Nothing
in the Plan shall be construed to limit the right of the Company (a) to
establish any other forms of incentives or compensation for Directors of the
Company, any Subsidiary or any Noncorporate Affiliate, or (b) to grant or assume
options or other rights or awards otherwise than under the Plan in connection
with any proper corporate purpose including but not by way of limitation, the
grant or assumption of options in connection with the acquisition by purchase,
lease, merger, consolidation or otherwise, of the business, stock or assets of
any corporation, partnership, limited liability company, firm or association.

            6.7.  Compliance with Laws. The Plan, the granting and vesting of
Options under the Plan and the issuance and delivery of shares of Common Stock
and the payment of money under the Plan or under Options granted hereunder are
subject to compliance with all applicable federal and state laws, rules and
regulations (including but not limited to state and federal securities law and
federal margin requirements) and to such approvals by any listing, regulatory or
governmental authority as may, in the opinion of counsel for the Company, be
necessary or advisable in connection therewith. Any securities delivered under
the Plan shall be

                                       11
<PAGE>

subject to such restrictions, and the person acquiring such securities shall, if
requested by the Company, provide such assurances and representations to the
Company as the Company may deem necessary or desirable to assure compliance with
all applicable legal requirements. To the extent permitted by applicable law,
the Plan and Options granted hereunder shall be deemed amended to the extent
necessary to conform to such laws, rules and regulations.

            6.8.  Tax Withholding. The Company shall be entitled to require
payment in cash or deduction from other compensation payable to each Holder of
any sums required by federal, state or local tax law to be withheld with respect
to the issuance, vesting, exercise or payment of any Options. The Administrator
may in its discretion and in satisfaction of the foregoing requirement allow
such Holder to elect to have the Company withhold shares of Common Stock
otherwise issuable under such Options (or allow the return of shares of Common
Stock) having a Fair Market Value equal to the sums required to be withheld.
Notwithstanding any other provision of the Plan, the number of shares of Common
Stock which may be withheld with respect to the issuance, vesting, exercise or
payment of any Options (or which may be repurchased from the Holder of such
Option within six months after such shares of Common Stock were acquired by the
Holder from the Company) in order to satisfy the Holder's federal and state
income and payroll tax liabilities with respect to the issuance, vesting,
exercise or payment of the Option shall be limited to the number of shares which
have a Fair Market Value on the date of withholding or repurchase equal to the
aggregate amount of such liabilities based on the minimum statutory withholding
rates for federal and state income tax and payroll tax purposes that are
applicable to such supplemental taxable income.

            6.9.  Titles. Titles are provided herein for convenience only and
are not to serve as a basis for interpretation or construction of the Plan.

            6.10. Governing Law. The Plan and any agreements hereunder shall be
administered, interpreted and enforced under the internal laws of the State of
Delaware without regard to conflicts of laws thereof.
