with the Corporation subsequent to the date the Stock Option Agreement, attached
as Exhibit A and signed by the Participant, is delivered to the Corporation;

                  (ii) as to the other fifty (50%) percent of the shares granted

employment with the Corporation subsequent to the date the Stock Option
Agreement attached as Exhibit A executed by the Participant is delivered to the
Corporation; and

                  (iii) only as to vested Options after termination of

                  Corporation for any reason, including death or disability
                  shall be deemed an offer to the Corporation to sell such
                  vested Options to the Corporation, upon the following terms:

                  (i) the Price shall be the difference between the Option Price
and the "fair market value" per Share as determined in accordance with the
provisions of this Plan;

                                       -3-

<PAGE>

                  (ii) if the Corporation does not, within three (3) months
following Participant's termination of employment, purchase such vested Options,
such Options may be exercised in accordance with the terms of this Plan and the
Option Agreement.

or in part by giving to the Treasurer of the Corporation the Notice of Exercise

         (a)      None of the Shares shall be sold, exchanged, transferred,
                  pledged, hypothecated or otherwise disposed of unless they
                  first, by written notice, have been offered to the Corporation
                  for purchase with appropriate adjustment for any change in the
                  number of Shares due to events described in Section 11 and the
                  Corporation does not, within three (3) months following such
                  offer, purchase the Shares and make payment in full therefor
                  for a price per Share which shall be equal to the "fair market
                  value" per Share determined in accordance with the provisions
                  of this Plan.

         (b)      The termination of a Participant's employment with the
                  Corporation for any reason, including death or disability,
                  shall be deemed an offer to the Corporation to sell such
                  Shares upon the terms set forth in Section 7.7(a) above. The
                  Price shall be the "fair market value" per Share as determined
                  in accordance with the provisions of this Plan.

         (c)      With respect to any Shares which may be transferred by
                  operation of law, Corporation's receipt of notice of any such
                  transfer shall be deemed an offer to sell such shares in the
                  same manner and upon the same terms as if such event was a
                  termination of the Participant's employment.

         (d)      If the Board and the Shareholders of the Corporation approve
                  the acceptance of an offer to purchase all or a majority
                  interest in the outstanding Shares of the Corporation which is
                  not acceptable to a Participant, the Participant's refusal to
                  accept such an offer shall be deemed an offer to the
                  Corporation to sell such Shares for the higher of the offer
                  price or the price that would be payable if the Participant
                  had terminated his employment with the Corporation as of the
                  time of such refusal.

         (e)      The restrictions set forth in this Section 7 shall lapse as to
                  any Shares the Corporation fails to repurchase after they have
                  been offered to the Corporation as described in Section 7.

         (f)      All notices in writing required pursuant to this Section 7
                  will be sufficient only if

                                       -4-

<PAGE>

                  actually delivered or if sent via registered or certified
                  mail, postage pre-paid to the Corporation, attention Treasurer
                  at its principal office within the City of Warrenville and
                  will be deemed conclusively deemed given on the date of
                  delivery, if delivered, or on the third (3rd ) business day
                  following the date of such mailing, if mailed.

         (g)      The restrictions set forth in this Section 7 shall be
                  applicable to all Options granted under this Plan and all
                  Shares issued pursuant to the exercise of any Option under
                  this Plan.

         8.  TERMINATION OF EMPLOYMENT.

         TERMINATION OF OPTIONS - If a Participant ceases to be employed by the
Corporation, his/her non-vested Options shall terminate immediately and his/her
Shares acquired via exercise of Options shall be subject to the option to
purchase as set forth in this Plan. The Committee shall determine in each case
whether a leave of absence shall constitute a termination of employment. Any
such determination of the Committee shall be final and conclusive, unless
overruled by the Board.

         9.  NO OBLIGATION OF EXERCISE OPTION.

         The granting of an Option shall impose no obligation upon the
Participant to exercise such Option.

         10. NONASSIGNABILITY.

         Options shall not be transferable other than by will or by the law of
descent and distribution, and during a Participant's lifetime shall be
exercisable only by such Participant.

         11. EFFECT OF CHANGE IN SHARES SUBJECT TO THE PLAN.

         The aggregate number of Shares available for Options under the Plan,
the shares subject to any Option, and the price per share shall all be
proportionately adjusted for any increase or decrease in the number of issued
Shares subsequent to the effective date of the Plan resulting from (1) a
subdivision or consolidation of shares or any other capital adjustment, (2) the
payment of a stock dividend, or (3) other increase or decrease in such shares
effected without receipt of consideration by the Corporation. If the Corporation
shall be the surviving corporation in any merger or consolidation, the Option
shall pertain, apply and relate to the securities to which a holder of the
number of Shares subject to the Option would have been entitled after the merger
or consolidation. Upon dissolution or liquidation of the Corporation, or upon a
merger or consolidation in which the Corporation is not the surviving
corporation or upon sale of a majority of the then outstanding shares of the
Corporation or substantially all of the assets of the Corporation, all Options
outstanding under the Plan shall terminate; provided, however, that each
Participant shall have the right, immediately prior to such dissolution or
liquidation, or such merger or consolidation, or such sale of a majority of the
shares or assets, to exercise such Participant's vested Options in whole or in
part, but only to the extent that such Options were otherwise exercisable under
the terms of the Plan but had not been exercised at the exercise date.
Non-vested Options shall be exercisable only in the event of the sale or
exchange of (a majority)

                                       -5-

<PAGE>

(fifty one (51%) percent) of the shares or the sale of substantially all of the
assets of the Corporation.

         12. AMENDMENT AND TERMINATION.

         The Board, by resolution, may terminate, amend or revise the Plan with
respect to any shares as to which Options have not been granted. Neither the
Board nor the Committee may, without the consent of the holder of an Option,
alter or impair any Option previously granted under the Plan, except as
authorized herein. Unless sooner terminated, the Plan shall remain in effect for
a period of ten years from the date of the Plan's adoption by the Board.
Termination of the Plan shall not affect any Option previously granted.

         13. AGREEMENT AND REPRESENTATION OF EMPLOYEES.

         As a condition to the exercise of any portion of an Option, the
Corporation may require the person exercising such Option to represent and
warrant at the time of such exercise that any Shares acquired at exercise are
being acquired only for investment and without any present intention to sell or
distribute such shares, if, in the opinion of counsel for the Corporation, such
a representation is required under the Securities Act of 1933 or any other
applicable law, regulation or rule of any governmental agency.

         14. RESERVATION OF SHARES.

         The Corporation, during the term of this Plan, will at all times
reserve and keep available, and will seek or obtain from any regulatory body
having jurisdiction any requisite authority necessary to issue and to sell, the
number of Shares that shall be sufficient to satisfy the requirements of this
Plan. The inability of the Corporation to obtain from any regulatory body having
jurisdiction the authority deemed necessary by counsel for the Corporation for
the lawful issuance and sale of its Shares hereunder shall relieve the
Corporation of any liability in respect of the failure to issue or sell Shares
as to which the requisite authority has not been obtained.

         15. EFFECTIVE DATE OF PLAN.

         The Plan shall be effective from the date that the Plan is approved by
the Board, which was January 2, 1997.

         1. PURPOSE. The purpose of this Plan is to provide incentives to
attract, retain and motivate eligible persons whose present and potential
contributions are important to the success of the Company, its Parent and
Subsidiaries, by offering them an opportunity to participate in the Company's
future performance through awards of Options and Restricted Stock. Capitalized
terms not defined in the text are defined in Section 22 hereof. This Plan is

                  2.1 Number of Shares Available. Subject to Sections 2.2 and 17
hereof, the total number of Shares reserved and available for grant and issuance
pursuant to this Plan will be 3,530,005 Shares (or such lesser number of Shares
as permitted under Section 260.140.45 of Title 10 of the California Code of
Regulations, if applicable, or other comparable or applicable state law, if any)
plus the Shares described in the following two sentences. Subject to Sections
2.2 and 17 hereof, Shares will again be available for grant and issuance in
connection with future Awards under this Plan that: (i) are subject to issuance
upon exercise of an Option but cease to be subject to such Option for any reason
other than exercise of such Option; (ii) are issued pursuant to an Award granted
pursuant to this Plan but are repurchased by the Company at the original issue
price; or (iii) are subject to an Award that otherwise terminates without Shares
being issued.

                  2.2 Adjustment of Shares. In the event that the number of
outstanding shares of the Company's Common Stock is changed by a stock dividend,
recapitalization, stock split, reverse stock split, subdivision, combination,
reclassification or similar change in the capital structure of the Company
without consideration, then (i) the number of Shares reserved for issuance under
this Plan, (ii) the Exercise Prices of and number of Shares subject to
outstanding Options and (iii) the Purchase Prices of and number of Shares
subject to other outstanding Awards will be proportionately adjusted, subject to
any required action by the Board or the shareholders of the Company and
compliance with applicable securities laws; provided, however, that fractions of
a Share will not be issued but will either be paid in cash at the Fair Market
Value of such fraction of a Share or will be rounded down to the nearest whole
Share, as determined by the Committee.

         3. ELIGIBILITY. ISOs (as defined in Section 5 hereof) may be granted
only to employees (including officers and directors who are also employees) of
the Company or of a Parent or Subsidiary of the Company. NQSOs (as defined in

Without limitation, the Committee will have the authority to:

          (a)  construe and interpret this Plan, any Award Agreement and any
               other agreement or document executed pursuant to this Plan;

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

          (f)  determine whether Awards will be granted singly, in combination
               with, in tandem with, in replacement of, or as alternatives to,
               other Awards under this Plan or awards under any other incentive
               or compensation plan of the Company or any Parent or Subsidiary
               of the Company;

          (g)  grant waivers of any conditions of this Plan or any Award;

          (h)  determine the terms of vesting, exercisability and payment of
               Awards;

          (i)  correct any defect, supply any omission, or reconcile any

          (j)  determine whether an Award has been earned; and

          4.2 Committee Discretion. Unless in contravention of any express terms
of this Plan or Award, any determination made by the Committee with respect to
any Award will be made in its sole discretion either (i) at the time of grant of
the Award, or (ii) subject to Section 5.9 hereof, at any later time. Any such
determination will be final and binding on the Company and on all persons having
an interest in any Award under this Plan. The Committee may delegate to one or
more officers of the Company the authority to grant an Award under this Plan,
provided such officer or officers are members of the Board.

                                       -2-

     5. OPTIONS. The Committee may grant Options to eligible persons described
in Section 3 hereof and will determine whether such Options will be Incentive
Stock Options within the meaning of the Code ("ISOs") or Nonqualified Stock
Options ("NQSOs"), the number of Shares subject to the Option, the Exercise
Price of the Option, the period during which the Option may be exercised, and
all other terms and conditions of the Option, subject to the following:

          5.1. Form of Option Grant. Each Option granted under this Plan will be
evidenced by an Award Agreement which will expressly identify the Option as an
ISO or an NQSO ("Stock Option Agreement"), and will be in such form and contain
such provisions (which need not be the same for each Participant) as the
Committee may from time to time approve, and which will comply with and be
subject to the terms and conditions of this Plan.

          5.2. Date of Grant. The date of grant of an Option will be the date on
which the Committee makes the determination to grant such Option, unless a later
date is otherwise specified by the Committee. The Stock Option Agreement and a
copy of this Plan will be delivered to the Participant within a reasonable time
after the granting of the Option.

          5.3. Exercise Period. Options may be exercisable immediately but
subject to repurchase pursuant to Section 11 hereof or may be exercisable within
the times or upon the events determined by the Committee as set forth in the
Stock Option Agreement governing such Option; provided, however, that no Option
will be exercisable after the expiration of ten (10) years from the date the
Option is granted; and provided further that no ISO granted to a person who
directly or by attribution owns more than ten percent (10%) of the total
combined voting power of all classes of stock of the Company or of any Parent or
Subsidiary of the Company ("Ten Percent Shareholder") will be exercisable after
the expiration of five (5) years from the date the ISO is granted. The Committee
also may provide for Options to become exercisable at one time or from time to
time, periodically or otherwise, in such number of Shares or percentage of
Shares as the Committee determines. Subject to earlier termination of the Option
as provided herein, each Participant who is not an officer, director or
consultant of the Company or of a Parent or Subsidiary of the Company shall have
the right to exercise an Option granted hereunder at the rate of no less than
twenty percent (20%) per year over five (5) years from the date such Option is
granted.

          5.4. Exercise Price. The Exercise Price of an Option will be
determined by the Committee when the Option is granted and may not be less than
eighty-five percent (85%) of the Fair Market Value of the Shares on the date of
grant; provided that (i) the Exercise Price of an ISO will not be less than one
hundred percent (100%) of the Fair Market Value of the Shares on the date of
grant and (ii) the Exercise Price of any Option granted to a Ten Percent
Shareholder will not be less than one hundred ten percent (110%) of the Fair
Market Value of the Shares on the date of grant. Payment for the Shares
purchased must be made in accordance with Section 7 hereof.

          5.5. Method of Exercise. Options may be exercised only by delivery to
the Company of a written stock option exercise agreement (the "Exercise
Agreement") in a form approved by the Committee (which need not be the same for
each Participant). The Exercise Agreement will state (i) the number of Shares
being purchased, (ii) the restrictions imposed on the Shares purchased under
such Exercise Agreement, if any, and (iii) such representations and

                                       -3-

<PAGE>

agreements regarding Participant's investment intent and access to information
and other matters, if any, as may be required or desirable by the Company to
comply with applicable securities laws. Participant shall execute and deliver to
the Company the Exercise Agreement together with payment in full of the Exercise
Price, and any applicable taxes, for the number of Shares being purchased.

          5.6. Termination. Subject to earlier termination pursuant to Sections
17 and 18 hereof and notwithstanding the exercise periods set forth in the Stock
Option Agreement, exercise of an Option will always be subject to the following:

          (a)  If the Participant is Terminated for any reason other than death,
               Disability or for Cause, then the Participant may exercise such
               Participant's Options only to the extent that such Options are
               exercisable upon the Termination Date. Such Options must be
               exercised by the Participant, if at all, as to all or some of the
               Vested Shares calculated as of the Termination Date, within three
               (3) months after the Termination Date (or within such shorter
               time period, not less than thirty (30) days, or within such
               longer time period, not exceeding five (5) years, after the
               Termination Date as may be determined by the Committee, with any
               exercise beyond three (3) months after the Termination Date
               deemed to be an NQSO) but in any event, no later than the
               expiration date of the Options.

          (b)  If the Participant is Terminated because of Participant's death
               or Disability (or the Participant dies within three (3) months
               after a Termination other than for Cause), then Participant's
               Options may be exercised only to the extent that such Options are
               exercisable by Participant on the Termination Date. Such options
               must be exercised by Participant (or Participant's legal
               representative or authorized assignee), if at all, as to all or
               some of the Vested Shares calculated as of the Termination Date,
               within twelve (12) months after the Termination Date (or within
               such shorter time period, not less than six (6) months, or within
               such longer time period, not exceeding five (5) years, after the
               Termination Date as may be determined by the Committee, with any
               exercise beyond (i) three (3) months after the Termination Date
               when the Termination is for any reason other than the
               Participant's death or disability, within the meaning of Section
               22(e)(3) of the Code, or (ii) twelve (12) months after the
               Termination Date when the Termination is for Participant's
               disability, within the meaning of Section 22(e)(3) of the Code,
               deemed to be an NQSO) but in any event no later than the
               expiration date of the Options.

          (c)  If the Participant is terminated for Cause, then Participant's
               Options shall expire on such Participant's Termination Date, or
               at such later time and on such conditions as are determined by
               the Committee.

          5.7. Limitations on Exercise. The Committee may specify a reasonable
minimum number of Shares that may be purchased on any exercise of an Option,
provided that such

                                       -4-

<PAGE>

minimum number will not prevent Participant from exercising the Option for the
full number of Shares for which it is then exercisable.

          5.8. Limitations on ISOs. The aggregate Fair Market Value (determined
as of the date of grant) of Shares with respect to which ISOs are exercisable
for the first time by a Participant during any calendar year (under this Plan or
under any other incentive stock option plan of the Company or any Parent or
Subsidiary of the Company) will not exceed One Hundred Thousand Dollars
($100,000). If the Fair Market Value of Shares on the date of grant with respect
to which ISOs are exercisable for the first time by a Participant during any
calendar year exceeds One Hundred Thousand Dollars ($100,000), then the Options
for the first One Hundred Thousand Dollars ($100,000) worth of Shares to become
exercisable in such calendar year will be ISOs and the Options for the amount in
excess of One Hundred Thousand Dollars ($100,000) that become exercisable in
that calendar year will be NQSOs. For this purpose, Options will be taken into
account in the order in which they were granted. In the event that the Code or
the regulations promulgated thereunder are amended after the Effective Date (as
defined in Section 18 hereof) to provide for a different limit on the Fair
Market Value of Shares permitted to be subject to ISOs, then such different
limit will be automatically incorporated herein and will apply to any Options
granted after the effective date of such amendment.

          5.9. Modification, Extension or Renewal. The Committee may modify,
extend or renew outstanding Options and authorize the grant of new Options in
substitution therefor, provided that any such action may not, without the
written consent of a Participant, impair any of such Participant's rights under
any Option previously granted. Any outstanding ISO that is modified, extended,
renewed or otherwise altered will be treated in accordance with Section 424(h)
of the Code. Subject to Section 5.10 hereof, the Committee may reduce the
Exercise Price of outstanding Options without the consent of Participants by a
written notice to them; provided, however, that the Exercise Price may not be
reduced below the minimum Exercise Price that would be permitted under Section
5.4 hereof for Options granted on the date the action is taken to reduce the
Exercise Price.

          5.10. No Disqualification. Notwithstanding any other provision in this
Plan, no term of this Plan relating to ISOs will be interpreted, amended or
altered, nor will any discretion or authority granted under this Plan be
exercised, so as to disqualify this Plan under Section 422 of the Code or,
without the consent of the Participant, to disqualify any Participant's ISO
under Section 422 of the Code.

     6. RESTRICTED STOCK. A Restricted Stock Award is an offer by the Company to
sell to an eligible person Shares that are subject to certain specified
restrictions. The Committee will determine to whom an offer will be made, the
number of Shares the person may purchase, the Purchase Price, the restrictions
to which the Shares will be subject, and all other terms and conditions of the
Restricted Stock Award, subject to the following:

          6.1. Form of Restricted Stock Award. All purchases under a Restricted
Stock Award made pursuant to this Plan will be evidenced by an Award Agreement
("Restricted Stock Purchase Agreement") that will be in such form (which need
not be the same for each Participant) as the Committee will from time to time
approve, and will comply with and be subject to the terms and conditions of this
Plan. The Restricted Stock Award will be accepted by

                                       -5-

<PAGE>

the Participant's execution and delivery of the Restricted Stock Purchase
Agreement and full payment for the Shares to the Company within thirty (30) days
from the date the Restricted Stock Purchase Agreement is delivered to the
person. If such person does not execute and deliver the Restricted Stock
Purchase Agreement along with full payment for the Shares to the Company within
such thirty (30) days, then the offer will terminate, unless otherwise
determined by the Committee.

         6.2. Purchase Price. The Purchase Price of Shares sold pursuant to a
Restricted Stock Award will be determined by the Committee and will be at least
eighty-five percent (85%) of the Fair Market Value of the Shares on the date the
Restricted Stock Award is granted or at the time the purchase is consummated,
except in the case of a sale to a Ten Percent Shareholder, in which case the
Purchase Price will be one hundred percent (100%) of the Fair Market Value on
the date the Restricted Stock Award is granted or at the time the purchase is
consummated. Payment of the Purchase Price must be made in accordance with
Section 7 hereof.

         6.3. Restrictions. Restricted Stock Awards may be subject to the
restrictions set forth in Section 11 hereof or such other restrictions not
inconsistent with Section 25102(o) of the California Corporations Code, if
applicable, or other comparable or applicable state law, if any.

     7. PAYMENT FOR SHARE PURCHASES.

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

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

         (b)  by surrender of shares that: (i) either (A) have been owned by
              Participant for more than six (6) months and have been paid for
              within the meaning of SEC Rule 144 (and, if such shares were
              purchased from the Company by use of a promissory note, such note
              has been fully paid with respect to such shares) or (B) were
              obtained by Participant in the public market and (ii) are clear
              of all liens, claims, encumbrances or security interests;

         (c)  by tender of a full recourse promissory note having such terms as
              may be approved by the Committee and bearing interest at a rate
              sufficient to avoid imputation of income under Sections 483 and
              1274 of the Code; provided, however, that Participants who are
              not employees or directors of the Company will not be entitled to
              purchase Shares with a promissory note unless the note is
              adequately secured by collateral other than the Shares;

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

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

                                       -6-

<PAGE>

                           (i)      through a "same day sale" commitment from
                                    the Participant and a broker-dealer that is
                                    a member of the National Association of
                                    Securities Dealers (an "NASD Dealer")
                                    whereby the Participant irrevocably elects
                                    to exercise the Option and to sell a portion
                                    of the Shares so purchased sufficient to pay
                                    the total Exercise Price, and whereby the
                                    NASD Dealer irrevocably commits upon receipt
                                    of such Shares to forward the total Exercise
                                    Price directly to the Company; or

                           (ii)     through a "margin" commitment from the
                                    Participant and an NASD Dealer whereby the
                                    Participant irrevocably elects to exercise
                                    the Option and to pledge the Shares so
                                    purchased to the NASD Dealer in a margin
                                    account as security for a loan from the NASD
                                    Dealer in the amount of the total Exercise
                                    Price, and whereby the NASD Dealer
                                    irrevocably commits upon receipt of such
                                    Shares to forward the total Exercise Price
                                    directly to the Company; or

                  (f)      by any combination of the foregoing.

                  7.2. Loan Guarantees. The Committee may, in its sole
discretion, elect to assist the Participant in paying for Shares purchased under
this Plan by authorizing a guarantee by the Company of a third-party loan to the
Participant.

         8. WITHHOLDING TAXES.

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

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

         9. PRIVILEGES OF STOCK OWNERSHIP.

                  9.1. Voting and Dividends. No Participant will have any of the
rights of a shareholder with respect to any Shares until the Shares are issued
to the Participant. After Shares

                                       -7-

<PAGE>

are issued to the Participant, the Participant will be a shareholder and have
all the rights of a shareholder with respect to such Shares, including the right
to vote and receive all dividends or other distributions made or paid with
respect to such Shares; provided, that if such Shares are Restricted Stock, then
any new, additional or different securities the Participant may become entitled
to receive with respect to such Shares by virtue of a stock dividend, stock
split or any other change in the corporate or capital structure of the Company
will be subject to the same restrictions as the Restricted Stock. The
Participant will have no right to retain such stock dividends or stock
distributions with respect to Unvested Shares that are repurchased pursuant to
Section 11 hereof. The Company will comply with Section 260.140.1 of Title 10 of
the California Code of Regulations, if applicable, or other comparable or
applicable state law, if any, with respect to the voting rights of Common Stock
or other applicable law.

                  9.2. Financial Statements. The Company will provide financial
statements to each Participant annually during the period such Participant has
Awards outstanding, or as otherwise required under Section 260.140.46 of Title
10 of the California Code of Regulations, if applicable, or other comparable or
applicable state law, if any. Notwithstanding the foregoing, the Company will
not be required to provide such financial statements to Participants when
issuance is limited to key employees whose services in connection with the
Company assure them access to equivalent information.

         10. TRANSFERABILITY. Awards granted under this Plan, and any interest
therein, will not be transferable or assignable by Participant, other than by
will or by the laws of descent and distribution, and may not be made subject to
execution, attachment or similar process. During the lifetime of the Participant
an Award will be exercisable only by the Participant or Participant's legal
representative and any elections with respect to an Award may be made only by
the Participant or Participant's legal representative.

         11. RESTRICTIONS ON SHARES.

                  11.1 Right of First Refusal. At the discretion of the
Committee, the Company may reserve to itself and/or its assignee(s) in the Award
Agreement a right of first refusal to purchase all Shares that a Participant (or
a subsequent transferee) may propose to transfer to a third party, unless
otherwise not permitted by Section 25102(o) of the California Corporations Code,
if applicable, or other comparable or applicable state law, if any, provided
that such right of first refusal terminates upon the Company's initial public
offering of Common Stock pursuant to an effective registration statement filed
under the Securities Act.

                  11.2 Right of Repurchase. At the discretion of the Committee,
the Company may reserve to itself and/or its assignee(s) in the Award Agreement
a right to repurchase Unvested Shares held by a Participant for cash and/or
cancellation of purchase money indebtedness owed to the Company by the
Participant following such Participant's Termination at any time within the
later of ninety (90) days after the Participant's Termination Date and the date
the Participant purchases Shares under the Plan at the Participant's Exercise
Price or Purchase Price, as the case may be, provided that, unless the
Participant is an officer, director or consultant of the Company or of a Parent
or Subsidiary of the Company, such right of repurchase lapses at the rate of no
less than twenty percent (20%) per year over five (5) years from: (a) the date
of grant of the Option or (b) in the case of Restricted Stock, the date the
Participant purchases the Shares.

                                       -8-

<PAGE>

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

         13. ESCROW; PLEDGE OF SHARES. To enforce any restrictions on a
Participant's Shares set forth in Section 11 hereof, the Committee may require
the Participant to deposit all certificates representing Shares, together with
stock powers or other instruments of transfer approved by the Committee,
appropriately endorsed in blank, with the Company or an agent designated by the
Company to hold in escrow until such restrictions have lapsed or terminated. The
Committee may cause a legend or legends referencing such restrictions to be
placed on the certificates. Any Participant who is permitted to execute a
promissory note as partial or full consideration for the purchase of Shares
under this Plan will be required to pledge and deposit with the Company all or
part of the Shares so purchased as collateral to secure the payment of
Participant's obligation to the Company under the promissory note; provided,
however, that the Committee may require or accept other or additional forms of
collateral to secure the payment of such obligation and, in any event, the
Company will have full recourse against the Participant under the promissory
note notwithstanding any pledge of the Participant's Shares or other collateral.
In connection with any pledge of the Shares, Participant will be required to
execute and deliver a written pledge agreement in such form as the Committee
will from time to time approve.

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

         15. SECURITIES LAW AND OTHER REGULATORY COMPLIANCE. This Plan is
intended to comply with Section 25102(o) of the California Corporations Code, if
applicable, or other comparable or applicable state law, if any. Any provision
of this Plan which is inconsistent with Section 25102(o), if applicable, or
other comparable, or applicable state law, if any, without further act or
amendment by the Company or the Board, shall be reformed to comply with such
requirements. An Award will not be effective unless such Award is in compliance
with all applicable federal and state securities laws, rules and regulations of
any governmental body, and the requirements of any stock exchange or automated
quotation system upon which the Shares may then be listed or quoted, as they are
in effect on the date of grant of the Award and also on the date of exercise or
other issuance. Notwithstanding any other provision in this Plan, the Company
will have no obligation to issue or deliver certificates for Shares under this
Plan prior to (i) obtaining any approvals from governmental agencies that the
Company determines are necessary or advisable, and/or (ii) compliance with any
exemption, completion of any registration or other qualification of such Shares
under any state or federal law or ruling of any governmental body that the
Company determines to be necessary or advisable. The Company will be under no
obligation to register the Shares with the SEC or to effect compliance with the

                                       -9-

<PAGE>

exemption, registration, qualification or listing requirements of any state
securities laws, stock exchange or automated quotation system, and the Company
will have no liability for any inability or failure to do so.

         16. NO OBLIGATION TO EMPLOY. Nothing in this Plan or any Award granted
under this Plan will confer or be deemed to confer on any Participant any right
to continue in the employ of, or to continue any other relationship with, the
Company or any Parent or Subsidiary of the Company or limit in any way the right
of the Company or any Parent or Subsidiary of the Company to terminate
Participant's employment or other relationship at any time, with or without
Cause.

         17. CORPORATE TRANSACTIONS.

                  17.1. Assumption or Replacement of Awards by Successor or
Acquiring Corporation. In the event of (i) a merger or consolidation in which
the Company is not the surviving corporation (other than a merger or
consolidation with a wholly owned subsidiary, a reincorporation, or other
transaction in which there is no substantial change in the shareholders of the
corporation and the Options granted under this Plan are assumed by the successor
corporation), (ii) a dissolution or liquidation of the Company, (iii) the sale
of substantially all of the assets of the Company, or (iv) any other transaction
which qualifies as a "corporate transaction" under Section 424(a) of the Code
wherein the shareholders of the Company give up all of their equity interest in
the Company (except for the acquisition of all or substantially all of the
outstanding shares of the Company), any or all outstanding Options and the Plan
may be assumed by the successor corporation, which assumption shall be binding
on all Optionees. In the alternative, the successor corporation may substitute
an equivalent option or provide substantially similar consideration to Optionees
as was provided to shareholders (after taking into account the existing
provisions of Optionee's options, such as the exercise price and the vesting
schedule). The successor corporation may also issue, in place of outstanding
shares of the Company held by Optionee as a result of the exercise of an Option
that is subject to repurchase, substantially similar shares or other property
subject to similar repurchase restrictions no less favorable to Optionee. In the
event such successor corporation, if any, refuses to assume or substitute the
Options, as provided above, or if there is no successor corporation, such
Options shall expire in connection with such transaction at such time and on
such conditions as the Board shall determine.

                  17.2. Other Treatment of Awards. Subject to any greater rights
granted to Participants under the foregoing provisions of this Section 17, in
the event of the occurrence of any transaction described in Section 17.1 hereof,
any outstanding Awards will be treated as provided in the applicable agreement
or plan of merger, consolidation, dissolution, liquidation or sale of assets.

                  17.3. Assumption of Awards by the Company. The Company, from
time to time, also may substitute or assume outstanding awards granted by
another company, whether in connection with an acquisition of such other company
or otherwise, by either (i) granting an Award under this Plan in substitution of
such other company's award or (ii) assuming such award as if it had been granted
under this Plan if the terms of such assumed award could be applied to an Award
granted under this Plan. Such substitution or assumption will be permissible

                                       -10-

<PAGE>

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

     18. ADOPTION AND SHAREHOLDER APPROVAL. This Plan will become effective on
the date that it is adopted by the Board (the "Effective Date"). This Plan will
be approved by the shareholders of the Company consistent with applicable laws,
within twelve (12) months before or after the Effective Date. Upon the Effective
Date, the Board may grant Awards pursuant to this Plan; provided, however, that:
(i) no Option may be exercised prior to initial shareholder approval of this
Plan; (ii) no Option granted pursuant to an increase in the number of Shares
approved by the Board shall be exercised prior to the time such increase has
been approved by the shareholders of the Company; (iii) in the event that
initial shareholder approval is not obtained within the time period provided
herein, all Awards granted hereunder shall be canceled, any Shares issued
pursuant to any Award shall be canceled and any purchase of Shares issued
hereunder shall be rescinded; and (iv) Awards granted pursuant to an increase in
the number of Shares approved by the Board which increase is not timely approved
by shareholders shall be canceled, any Shares issued pursuant to any such Awards
shall be canceled, and any purchase of Shares subject to any such Award shall be
rescinded.

     19. TERM OF PLAN. Unless earlier terminated as provided herein, this Plan
will terminate ten (10) years from the Effective Date or, if earlier, the date
of shareholder approval.

     20. AMENDMENT OR TERMINATION OF PLAN. Subject to Section 5.9 hereof, the
Board may at any time terminate or amend this Plan in any respect, including
without limitation amendment of any form of Award Agreement or instrument to be
executed pursuant to this Plan; provided, however, that the Board will not,
without the approval of the shareholders of the Company, amend this Plan in any
manner that requires such shareholder approval pursuant to Section 25102(o) of
the California Corporations Code, if applicable, or other comparable or
applicable state law, if any, or the Code or the regulations promulgated
thereunder as such provisions apply to ISO plans.

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

             ---------------
(this "Option") to purchase the total number of shares of Common Stock of the
Company set forth above as Total Option Shares (the "Shares") at the Exercise
Price Per Share set forth above (the "Exercise Price"), subject to all of the
terms and conditions of this Agreement and the Plan. If designated as an
Incentive Stock Option above, the Option is intended to qualify as an "incentive
stock option" (the "ISO") within the meaning of Section 422 of the Internal
Revenue Code of 1986, as amended (the "Code").

         2.  Exercise Period.
             ---------------

             2.1   Exercise Period of Option. This Option is immediately
                   -------------------------
exercisable although the Shares issued upon exercise of the Option will be
subject to the restrictions on transfer and Repurchase Options set forth in
Sections 7, 9 and 18 below. Provided Participant continues to provide services
to the Company or any Subsidiary or Parent of the Company, the Option will
become vested as to portions of the Shares as follows: (i) this Option shall not
vest with respect to any of the Shares until September 8, 2000 (the "First
Vesting Date"); (ii) on the First Vesting Date the Option will become vested as
to twelve and one half percent (12.5%) of

                                       -15-

<PAGE>

the Shares; and (iii) thereafter at the end of each full succeeding month the
Option will become vested as to 2.0833% percent of the Shares until the Shares
are vested with respect to one hundred percent (100%) of the Shares. If
application of the vesting percentage causes a fractional share, such share
shall be rounded down to the nearest whole share for each month except for the
last month in such vesting period, at the end of which last month this Option
shall become vested for the full remainder of the Shares.

                  2.2 Vesting of Options. Shares that are vested pursuant to the
                      ------------------
schedule set forth in Section 2.1 are "Vested Shares." Shares that are not
vested pursuant to the schedule set forth in Section 2.1 are "Unvested Shares."

                  2.3 Expiration. The Option shall expire on the Expiration Date
                      ----------
set forth above or earlier as provided in Section 3 below or pursuant to Section
5.6 of the Plan.

         3.       Termination.

                  3.1 Termination for Any Reason Except Death, Disability or
                      -------------------------------------------------------
Cause. If Participant is Terminated for any reason, except death, Disability or
-----
for Cause, the Option, to the extent (and only to the extent) that it would have
been exercisable by Participant on the Termination Date, may be exercised by
Participant no later than three (3) months after the Termination Date, but in
any event no later than the Expiration Date.

                  3.2 Termination Because of Death or Disability. If Participant
                      ------------------------------------------
is Terminated because of death or Disability of Participant (or Participant dies
within three (3) months of Termination when Termination is for any reason other
than Participant's Disability or for Cause), the Option, to the extent that it
is exercisable by Participant on the Termination Date, may be exercised by
Participant (or Participant's legal representative) no later than twelve (12)
months after the Termination Date, but in any event no later than the Expiration
Date. Any exercise beyond (i) three (3) months after the Termination Date when
the Termination is for any reason other than the Participant's death or
disability, within the meaning of Section 22(e)(3) of the Code; or (ii) twelve
(12) months after the Termination Date when the termination is for Participant's
disability, within the meaning of Section 22(e)(3) of the Code, is deemed to be
an NQSO.

                  3.3 Termination for Cause. If Participant is Terminated for
                      ---------------------
Cause, then the Option will expire on Participant's Termination Date, or at such
later time and on such conditions as are determined by the Committee.

                  3.4 No Obligation to Employ. Nothing in the Plan or this
                      -----------------------
Agreement shall confer on Participant any right to continue in the employ of, or
other relationship with, the Company or any Parent or Subsidiary of the Company,
or limit in any way the right of the Company or any Parent or Subsidiary of the
Company to terminate Participant's employment or other relationship at any time,
with or without Cause.

         4.       Manner of Exercise.
                  ------------------

                  4.1 Stock Option Exercise Agreement. To exercise this Option,

purchased, (iii) any restrictions imposed on the Shares and (iv) any
representations, warranties and agreements regarding Participant's investment

Option, then such person must submit documentation reasonably acceptable to the
Company verifying that such person has the legal right to exercise the Option.

                  4.2 Limitations on Exercise. The Option may not be exercised
                      -----------------------
unless such exercise is in compliance with all applicable federal and state
securities laws, as they are in effect on the date of exercise. The Option may
not be exercised as to fewer than one hundred (100) Shares unless it is
exercised as to all Shares as to which the Option is then exercisable.

                  4.3 Payment. The Exercise Agreement shall be accompanied by
                      -------
full payment of the Exercise Price for the shares being purchased in cash (by

                           promissory note, such note has been fully paid with
                           respect to such shares); or (B) were obtained by
                           Participant in the open public market; and (ii) are
                           clear of all liens, claims, encumbrances or security

                           to exercise the Option and to sell a portion of the
                           Shares so purchased sufficient to pay for the total
                           Exercise Price and whereby the NASD Dealer
                           irrevocably commits upon receipt of such Shares to
                           forward the total Exercise Price directly to the
                           Company, or (ii) through a "margin" commitment from
                           Participant and an NASD Dealer whereby Participant
                           irrevocably elects to exercise the Option and to
                           pledge the Shares so purchased to the NASD Dealer in
                           a margin account as security for a loan from the NASD
                           Dealer in the amount of the total Exercise Price, and
                           whereby the NASD Dealer irrevocably commits upon
                           receipt of

                                       -17-

<PAGE>

                            such Shares to forward the total Exercise Price
                            directly to the Company; or

                      (e)   by any combination of the foregoing.

                  4.4 Tax Withholding. Prior to the issuance of the Shares upon
                      ---------------
exercise of the Option, Participant must pay or provide for any applicable
federal, state and local withholding obligations of the Company. If the
Committee permits, Participant may provide for payment of withholding taxes upon
exercise of the Option by requesting that the Company retain Shares with a Fair
Market Value equal to the minimum amount of taxes required to be withheld. In
such case, the Company shall issue the net number of Shares to the Participant
by deducting the Shares retained from the Shares issuable upon exercise.

                  4.5 Issuance of Shares. Provided that the Exercise Agreement
                      ------------------
and payment are in form and substance satisfactory to counsel for the Company,
the Company shall issue the Shares registered in the name of Participant,
Participant's authorized assignee, or Participant's legal representative, and
shall deliver certificates representing the Shares with the appropriate legends
affixed thereto.

         5.       Notice of Disqualifying Disposition of ISO Shares. If the
                  -------------------------------------------------
Option is an ISO, and if Participant sells or otherwise disposes of any of the
Shares acquired pursuant to the ISO on or before the later of (i) the date two
(2) years after the Date of Grant, and (ii) the date one (1) year after transfer
of such Shares to Participant upon exercise of the Option, Participant shall
immediately notify the Company in writing of such disposition. Participant
agrees that Participant may be subject to income tax withholding by the Company
on the compensation income recognized by Participant from the early disposition
by payment in cash or out of the current wages or other compensation payable to
Participant.

         6.       Compliance with Laws and Regulations. The Plan and this
                  ------------------------------------
Agreement are intended to comply with Section 25102(o) of the California
Corporations Code, if applicable, and any regulations relating thereto or other
comparable, applicable state law, if any. Any provision of this Agreement which
is inconsistent with Section 25102(o), if applicable, or other comparable or
applicable state law, if any, or any regulations relating thereto shall, without
further act or amendment by the Company or the Board, be reformed to comply with
the requirements of Section 25102(o) if applicable, or other comparable,
applicable state law, if any, and any regulations relating thereto. The exercise
of the Option and the issuance and transfer of Shares shall be subject to
compliance by the Company and Participant with all applicable requirements of
federal and state securities laws and with all applicable requirements of any
stock exchange on which the Company's Common Stock may be listed at the time of
such issuance or transfer. Participant understands that the Company is under no
obligation to register or qualify the Shares with the SEC, any state securities
commission or any stock exchange to effect such compliance.

         7.       Nontransferability of Option. The Option may not be
                  ----------------------------
transferred in any manner other than by will or by the laws of descent and
distribution and may be exercised during the lifetime of Participant only by
Participant or in the event of Participant's incapacity, by

                                       -18-

<PAGE>

Participant's legal representative. The terms of the Option shall be binding
upon the executors, administrators, successors and assigns of Participant.

         8.     [Reserved]

         9.     Company's Right of First Refusal. Before any Vested Shares held
                --------------------------------
by Participant or any transferee of such Vested Shares may be sold or otherwise
transferred (including without limitation a transfer by gift or operation of
law), the Company and/or its assignee(s) shall have an assignable right of first
refusal to purchase the Vested Shares to be sold or transferred on the terms and
conditions set forth in the Exercise Agreement (the "Right of First Refusal").
The Company's Right of First Refusal will terminate when the Company's
securities become publicly traded.

         10.    Tax Consequences. Set forth below is a brief summary as of the
                ----------------
Effective Date of the Plan of some of the federal and California tax
consequences of exercise of the Option and disposition of the Shares. THIS
SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT
TO CHANGE. PARTICIPANT SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THE OPTION
OR DISPOSING OF THE SHARES.

                10.1  Exercise of ISO. If the Option qualifies as an ISO, there
                      ---------------
will be no regular federal or California income tax liability upon the exercise
of the Option, although the excess, if any, of the Fair Market Value of the
Shares on the date of exercise over the Exercise Price will be treated as a tax
preference item for federal alternative minimum tax purposes and may subject the
Participant to the alternative minimum tax in the year of exercise.

                10.2  Exercise of Nonqualified Stock Option. If the Option does
                      -------------------------------------
not qualify as an ISO, there may be a regular federal and California income tax
liability upon the exercise of the Option. Participant will be treated as having
received compensation income (taxable at ordinary income tax rates) equal to the
excess, if any, of the Fair Market Value of the Shares on the date of exercise
over the Exercise Price. If Participant is a current or former employee of the
Company, the Company may be required to withhold from Participant's compensation
or collect from Participant and pay to the applicable taxing authorities an
amount equal to a percentage of this compensation income at the time of
exercise.

                10.3  Disposition of Shares. The following tax consequences may
                      ---------------------
apply upon disposition of the Shares.

                      (a) Incentive Stock Options. If the Shares are held for
                          -----------------------
more than twelve (12) months after the date of the transfer of the Shares
pursuant to the exercise of an ISO and are disposed of more than two (2) years
after the Date of Grant, any gain realized on disposition of the Shares will be
treated as long term capital gain for federal income tax purposes. If Shares
purchased under an ISO are disposed of within the applicable one (1) year or two
(2) year period, any gain realized on such disposition will be treated as
compensation income (taxable at ordinary income rates) to the extent of the
excess, if any, of the Fair Market Value of the Shares on the date of exercise
over the Exercise Price.

                                       -19-

<PAGE>

                (b) Nonqualified Stock Options. If the Shares are held for more
                    --------------------------
than twelve (12) months after the date of the transfer of the Shares pursuant to
the exercise of an NQSO, any gain realized on disposition of the Shares will be
treated as long term capital gain.

                (c) Withholding. The Company may be required to withhold from
                    -----------
the Participant's compensation or collect from the Participant and pay to the
applicable taxing authorities an amount equal to a percentage of this
compensation income.

         10.4.  Section 83(b) Election for Unvested Shares. With respect to
                ------------------------------------------
Unvested Shares, which are subject to the Repurchase Option, unless an election
is filed by the Participant with the Internal Revenue Service (and, if
necessary, the proper state taxing authorities), within 30 days of the purchase
                                                 --------------
of the Unvested Shares, electing pursuant to Section 83(b) of the Code (and
similar state tax provisions, if applicable) to be taxed currently on any
difference between the Exercise Price of the Unvested Shares and their Fair
Market Value on the date of purchase, there may be a recognition of taxable
income (including, where applicable, alternative minimum taxable income) to the
Participant, measured by the excess, if any, of the Fair Market Value of the
Unvested Shares at the time they cease to be Unvested Shares, over the Exercise
Price of the Unvested Shares.

     11. Privileges of Stock Ownership. Participant shall not have any of the
         -----------------------------
rights of a shareholder with respect to any Shares until the Shares are issued
to Participant.

     12. Interpretation. Any dispute regarding the interpretation of this
         --------------
Agreement shall be submitted by Participant or the Company to the Committee for
review. The resolution of such a dispute by the Committee shall be final and
binding on the Company and Participant.

     13. Entire Agreement. The Plan is incorporated herein by reference. This
         ----------------
Agreement and the Plan constitute the entire agreement of the parties and
supersede all prior undertakings and agreements with respect to the subject
matter hereof.

     14. Notices. Any notice required to be given or delivered to the
         -------
Company under the terms of this Agreement shall be in writing and addressed to
the Corporate Secretary of the Company at its principal corporate offices. Any
notice required to be given or delivered to Participant shall be in writing and
addressed to Participant at the address indicated above or to such other address
as such party may designate in writing from time to time to the Company. All
notices shall be deemed to have been given or delivered upon: (i) personal
delivery; (ii) three (3) days after deposit in the United States mail by
certified or registered mail (return receipt requested); (iii) one (1) business
day after deposit with any return receipt express courier (prepaid); or (iv) one
(1) business day after transmission by facsimile, rapifax or telecopier.

     15. Successors and Assigns. The Company may assign any of its rights
         ----------------------
under this Agreement including its rights to purchase Shares under the
Repurchase Option and the Right of First Refusal. This Agreement shall be
binding upon and inure to the benefit of the successors and assigns of the
Company. Subject to the restrictions on transfer set forth herein, this
Agreement shall be binding upon Participant and Participant's heirs, executors,
administrators, legal representatives, successors and assigns.

                                       -20-

         16. Severability. If any provision of this Agreement is determined by a
             ------------
court of law to be illegal or unenforceable, then such provision will be
enforced to the maximum extent possible and the other provisions will remain
fully effective and enforceable.

         17. Acceptance. Participant hereby acknowledges receipt of a copy of
             ----------
the Plan and this Agreement. Participant has read and understands the terms and
provisions thereof, and accepts the Option subject to all the terms and
conditions of the Plan and this Agreement. Participant acknowledges that there
may be adverse tax consequences upon exercise of the Option or disposition of
the Shares and that Participant should consult a tax adviser prior to such
exercise or disposition.

         18. Company's Repurchase Option for Unvested Shares. The Company, or
             -----------------------------------------------
its assignee, shall have the option to repurchase Participant's Unvested Shares
(as defined in Section 2.2 of this Agreement) on the terms and conditions set
forth in the Exercise Agreement (the "Repurchase Option") if Participant is
Terminated (as defined in the Plan) for any reason, or no reason, including
without limitation Participant's death, Disability (as defined in the Plan),
voluntary resignation or termination by the Company. Notwithstanding the
foregoing, the Company shall retain the Repurchase Option for Unvested Shares
only as to that number of Unvested Shares (whether or not exercised) that
exceeds the number of shares which remain unexercised.

         IN WITNESS WHEREOF, the Company has caused this Agreement to be
executed in triplicate by its duly authorized representative and Participant has
executed this Agreement in triplicate, effective as of the Date of Grant.
